This paper provides basic data for product developers by investigating the consumption status, consumer perception, and consumer demand on products using Aster Yomena. Two hundred ninety-five people over 20 years of age were analyzed according to gender and age. In the purchase of Aster Yomena products, men were the higher purchasers except for powder. In age, noodles, wild vegetables, jangajji, tteok, and powder were consumed by those older than 30 years. In an analysis of purchase when developing Aster Yomena products, the male purchase intention was higher in all items except for kalguksu in the staple, and male purchase intention was higher in only bibimbapseasoning among aster powder addition sauce and all items in dessert. The purchase intention of those older than 30 years was higher in all items of staples, aster powder addition sause and sause The purchase intention of those older than 30 yearse was higher in green vegetables juice and milk tea among drink, and all items except ice cream among dessert. An analysis of the popularization of Aster Yomena revealed higher perceptions of men in the medium (TV, internet, online cafe, agro-fishery market), experience program (area tourism, exposition), and product development (convenience food, recipe development). The medium (agro-fishery market), experience program, and product development were more recognized in their 30s or more. The products with aster yomana require the most effective marketing to men 30 years and older, and require a strategy that will interest those in their 20s. [ABSTRACT FROM AUTHOR]

Purpose: Ankle fractures with dislocations and pilon fractures at the distal tibia are usually associated with soft tissue damage caused by high-energy damage. Recently, a two-stage operation to perform internal fixation after the application of external fixation devices for stabilizing soft tissues has been accepted as the treatment of choice. This paper reports the clinical result of these injuries treated with threaded trans-calcaneal pin external fixation devices. Materials and Methods: Thirty-three patients diagnosed with ankle fractures with dislocations or tibial pilon fractures without open wounds. They underwent surgical treatment with threaded trans-calcaneal pin external fixation from January 2008 to February were enrolled in this study. This study evaluated the visual analogue scale (VAS), foot function index (FFI), and Olerud & Molander score as well as whether complications occurred. Results: The average VAS showed a meaningful decrease (p<0.001) from 7.4 before surgery to 2.6 after application of the external fixation device, and 1.4 at 12 months after surgery. The FFI also decreased significantly from 84.3 preoperatively to 20.3 at 12 months postoperatively (p<0.001). The Olerud & Molander score averaged 71.4 points, showing good clinical results. Complete bone union was observed in all patients. One patient each underwent debridement due to wound necrosis and infection in the pin insertion site. At the final follow-up, seven patients had posttraumatic ankle joint arthritis, according to a radiological examination. Conclusion: Manual reduction and external fixation using a threaded trans-calcaneal pin is a suitable surgical technique that is easy to perform and shows good clinical outcomes in stabilizing soft tissue damage in fractures and dislocations of ankle fracture or tibia pilon fractures in foot and ankle injury.

A postoperative hallux varus deformity is a dreaded complication of hallux valgus surgery. Several surgical options have been introduced to overcome this problem. This paper reports an uncommon case of a 68-year-old female patient who presented with a postoperative hallux varus deformity combined with a rupture of the flexor hallucis longus (FHL) tendon. She was treated successfully by a minimally invasive correctional osteotomy with open tenorrhaphy. With experience in treating this complicated case, it was noted that FHL could be transected during the trans-articular adductor tenotomy. Hence, extra caution is needed when the degree of hallux valgus deformity is excessive. To the best of the author's knowledge, correctional valgization osteotomy for a postoperative hallux varus deformity in a minimally invasive manner has not been reported. This case report is expected to benefit surgeons and their patients with severe hallux valgus deformity. [ABSTRACT FROM AUTHOR]

The musculoskeletal system can be damaged by massive contractions of the muscles in the case of systemic attacks by epilepsy. Several studies or case reports of multiple thoracic vertebrae fractures following generalized seizures without underlying diseases or falls have been reported, but there are few domestic studies or case reports. This paper reports the case of a 42-year-old male patient without any specific underlying disease, who was diagnosed with multiple fractures of the thoracic vertebrae caused by generalized myoclonic epilepsy during sleep.

Purpose: Soft tissue defects of the distal lower extremity are commonly accompanied by a fracture of the lower extremities. Theses defects are caused by the injury itself or by complications associated with surgical treatment of the fracture, which poses challenging problem. The reverse superficial sural artery flap (RSSAF) is a popular option for these difficult wounds. This paper reviews these cases and reports the clinical results. Materials and Methods: Between August 2003 and April 2018, patients who were treated with RSSAF for soft tissue defects of the lower third of the leg and ankle related to a fracture were reviewed. A total of 16 patients were involved and the mean follow-up period was 18 months. Eight cases (50.0%) of the defects were due to an open fracture, whereas the other eight cases (50.0%) were postoperative complication after closed fracture. The largest flap measured 10×15 cm2 and the mean size of the donor sites was 51.9 cm2. The flap survival and postoperative complications were evaluated. Results: All flaps survived without complete necrosis or failure. One case with partial necrosis of the flap was encountered, but the wound healed after debridement and repair. One case had a hematoma with a pseudoaneurysmal rupture of the distal tibial artery. On the other hand, the flap was intact and the wound healed after arterial ligation and flap advancement. A debulking operation was performed on three cases for cosmetic reasons and implant removal through the flap was performed in three cases. No flap necrosis was encountered after these additional operations. Conclusion: RSSAF is a relatively simple and safe procedure for reconstructing soft tissue defects following a fracture of the lower extremity that does not require microsurgical anastomosis. This can be a useful treatment option for soft tissue defects on the distal leg, ankle, and foot. [ABSTRACT FROM AUTHOR]

Studies on forest tree breeding (FTB) in South Korea started in the 1950s and have achieved remarkable outcomes through various techniques and methods such as selective breeding, cross breeding, introduction breeding, and biotechnology. Despite these outstanding achievements, no attempt has been made to objectively and quantitatively evaluate the results of domestic FTB research. Here, we quantitatively analyzed past research trends using keywords of published journal papers and compared the current domestic research level of FTB with the international level. Using various keywords in this field, we searched for research articles published in the Journal of Korean Society of Forest Science, the Korean Journal of Breeding Science, and the journals listed on the Science Citation Index from 1962 to present. The analysis of these studies showed that the research on FTB has grown quantitatively in Korea, and has been conducted on various subjects. Research topics from Korea, in terms of purpose and species, are not significantly different from those of foreign countries. The genus Pinus has been the major subject of FTB studies both domestically and internationally. However, in foreign FTB research, the trees used for research have diversified each year, while they were not diverse in Korea. The FTB research capacity of Korean national institutions, such as the National Institute of Forest Science, continues to dramatically increase, while the research capacity of universities is relatively low. Based on the results of this analysis, it is necessary to establish a concrete and effective policy for future research and development of FTB. [ABSTRACT FROM AUTHOR]

This study identifies the success factors of the Cuban health care system centered on the relationship between the clinic and the community, in terms of the primary health care system which is community-based health care. It has been recognized that the primary health care system could be a practical approach to develop a better structure and a more functional health care system through building the community capacity. In community-based health care, the responsibility and the direct participation of people is crucial because the community empowerment leads to better health care for the people of the community, since they can take more control of local issues like health care. In this paper, we describe and define the characteristics of the relationship between the family doctors-nurses and the community members, using the method of participant observation, which is an anthropological approach. Given that Cuban health care has so far been analyzed mainly from the macro-policy perspective, the understanding of Cuba’s health care system at the community level, where the family doctor and nurse are closely connected to the local people, is a meaningful task.

The Republic of Korea is rapidly entering an aging society. With the aging of society, the overseas travel of the elderly is increasing rapidly. According to the Korea Tourism Organization, the number of overseas tourists aged 61 or older last year exceeded 2.5 million, of which over 80 were over 200,000. Age is no longer a limiting factor for traveling abroad, but traveling to unfamiliar places is certainly a challenge. Old people may experience a variety of problems, so special care should be taken. In particular, the aircraft cabin environment is different from the ground, so elderly travelers with respiratory or heart disease require special attention. In this paper, we want to know the precautions and how to prepare for the safe air travel for the elderly. [ABSTRACT FROM AUTHOR]

Obesity increases the risk of diabetes, hypertension, and cardiovascular diseases, ultimately contributing to mortality. The Korean Society for the Study of Obesity (KSSO) was established to improve the management of obesity through research and education; to that end, the Committee of Clinical Practice Guidelines of the KSSO reviews systemic evidence using expert panels to develop clinical guidelines. Weight-loss medications are effective adjuncts to diet, physical activity, and behavioral counseling for select Korean patients with type 2 diabetes and body mass index ≥ 25 kg/m². Potential benefits must be weighed against the potential risks of these medications. If a patient's response to weight-loss medications is < 5% weight loss after 3 months or if there are significant safety or tolerability issues at any time, the medication should be discontinued and alternative medications or treatment approaches should be considered. Long-term medications for enduring obesity have traditionally fallen into two major categories, centrally-acting anorexiant medications and peripherally acting medications, such as orlistat. In this paper, I provide the definition of obesity in Korea and describe anti-obesity medications currently available for long-term treatment in diabetes. [ABSTRACT FROM AUTHOR]

This paper introduces SNUDM, an analysis program for Ratcliff's diffusion model, which has been one of the most important models in cognitive psychology over the past 35 years and which has come to occupy an important place in cognitive neuroscience in recent years. The analysis tool is designed with the basic principles of easy comprehension and simplicity in use. A diffusion process was programmed as the limit of a simple random walk in a manner resembling Ratcliff & Tuerlinckx(2002). The response time distribution of the model was constructed by simulating the time taken by a random walk until it reaches a threshold with small steps. The optimal parameter values in the model are found to be the smallest value of the chi-square values obtained by comparing the resulting distribution and the experimental data using Simplex method. For simplicity and ease of use, the input file used here is created as a file containing the quantile of the reaction time, the trials and other information. The number of participants and the number of conditions required for such work programs are given in a way that answers the question. Using this analysis tool, the experimental data of Ratcliff, Gomez, & McKoon(2004) were analyzed. We found the very similar pattern of parameter values to Ratcliff et al.(2004) found. When comparing DMAT, fast-dm and SNUDM with the generated data, we found that when the number of trials is small, SNUDM estimates the boundary parameter to a value similar to fast-dm and less than the DMAT. In addition, when the number of trials was large, it was confirmed that all three tools estimate parameters similarly. [ABSTRACT FROM AUTHOR]

Acute ankle sprain is the most common injury in the lower extremities, and approximately 10% to 40% of acute lateral ankle ligament injury causes chronic pain or instability. For chronic symptoms lasting after an acute sprain, the possibility of joint damage, such as bony structures, ligaments, cartilage, and nerves around the ankle joint, should be considered. Patients with chronic lateral ankle instability usually complain of repeated sprains or giving way sensations. There has been steady progress in the treatment options until recently, however new treatments are still being attempted. This paper describes the causes, diagnosis, and recent trends in the conservative and operative treatment of chronic lateral ankle instability. [ABSTRACT FROM AUTHOR]

Non-spousal assisted reproductive technology(hereafter, ART) using donor's germ cells is being carried out. And there are some legal provisions related to ART. In reality, these provisions are not designed to perfectly respond to all possible problems surrounding it. Not long ago, the Supreme Court decided on a case about parent-child relationship between birth using third party sperm and father. In this case, there was a debate on whether to obtain "father's consent" on the formal side and to obtain "informed consent" on the practical side. Therefore, in this paper, I tried to analyze the problem centered on 'consent' among the various problems faced by ART using donor's sperm. So, I identified the important point of decision and the legal principles on the first, second and third decision of the case above-mentioned, and examined the contents and limitations of the ART related provisions on the 「Bioethics and Safety Act」. At least, if everyone agree, it is necessary to make it clear legally, and in particular, there should be legal clarity on the areas that should never be a problem. Under these judgements, I proposed the way to amend the informed consent related provisions on the 「Bioethics and Safety Act」 such as to expand legal scope of consent holders to all parties involved in ART, to modify the legal list to obtain consent to include the responsibilities and duties of consent holders, to obligate to provide the explanation of consent form to consent holders and to produce the guidelines by regulatory authorities to support the preparation of it and to help the IRB review about it, to clarify when it is possible and impossible to withdraw the consent during the ART process and to restrict the withdrawal of consent after the child's pregnancy and childbirth, to expend retention period of consent form written by consent holders to the time the child becomes an adult.

Bow hunter’s syndrome is a rare disease that shows the symptoms of vertebrobasilar insufficiency resulting from a dynamic obstruction or stenosis of the vertebral arteries during neck movement. This paper reports a case of a 59-year-old male who visited the emergency room with diplopia, tinnitus, and gait disturbance. Magnetic resonance imaging and angiography revealed a multiple cerebellar infarct, total obstruction of the right vertebral artery, and dynamic obstruction of the left vertebral artery during neck extension. As the infarction worsened, a thrombectomy was done. Posterior decompression and fusion at C5-6 were performed for the left vertebral artery. The left vertebral arterial patency was confirmed by intraoperative and postoperative angiography. No recurrence of the symptoms was observed for six months after surgery. Physicians need to pay attention to the diagnosis of vertebrobasilar insufficiency caused by an obstruction of the vertebral arteries during neck extension in cervical instability patients.

Manual therapy has undergone parallel development throughout many parts of the world dating back to ancient times for at least 2,500 years. The earliest historical reference to the practice of manual therapy in Greece, dates back to 400 B.C. Over the centuries, manual medicines have fallen in and out of favor with the medical profession. To truly understand the principle, it is important to know that manual therapy was initially the mainstay of the three leading alternative health care systems, osteopathy, chiropractic, and most notably physical therapy. These were all founded in the latter part of the 19th century in response to the shortcomings in allopathic medicine. Although it has been around for a long time and has been used all over the world, there are a few reports on manual therapy treatment, and most papers provided a low level of evidence. Despite the controversies over manual therapy, its use appears to be increasing gradually. This article reviews the history of manual therapy from ancient times to the present including Korean history, discusses the current state of knowledge on manual therapy, and informs physicians who manage musculoskeletal pain.

Purpose: This paper compares the clinical outcomes of patients who were treated with a cervical nerve block by ultrasound and C-arm and reports the complication. Materials and Methods: A total of 97 patients were treated with an ultrasound-guided nerve root block from May 1, 2015 to February 8, 2018. On the other hand, 94 patients were treated with a C-arm guided nerve root block. The consequences of the cervical pain and the radiating pain before and after the procedures were reviewed using the verbal numeric rating scale (VNRS). In addition, the complications related to the procedures from the daily notes from the chart were inspected. Results: Sixty-six cases out of 97 cases of ultrasound-guided nerve root block were enrolled in the study. The average age of the patients was 57 years, including 41 males and 25 females. Seventy seven out of 94 cases by a C-arm guided root block were included in the study. The average age of the patients was 55 years, including 40 males and 37 females. Before the nerve root block, the mean numeric rating pain scale (NRS) of the cervical pain in ultrasound-guided block decreased from 5.4 points to 2.7 points at three weeks and 1.4 points at six weeks (p=0.0023, p<0.001), and 3.1 points in the C-arm (p<0.001, p<0.001) at three weeks and 1.5 points at six weeks (p<0.001, p<0.001). In the case of radiating pain, the mean NRS in the ultrasound-guided nerve root block group improved from 6.3 points after the procedure to 2.8 points at three weeks and 1.5 points at six weeks (p<0.001, p<0.001). In the C-arm guided nerve root block group, the NRS improved from 7.4 points after the procedure to 3.3 points at three weeks and 1.9 points at six weeks. In the case of complications, Horner's syndrome and propriospinal myoclonus were observed in one case of C-arm guided block group. Conclusion: The clinical results of the patients who underwent ultrasound-guided cervical nerve root block were not significantly different from those who underwent a C-arm guided cervical nerve root block.

Evolutionary research on mental disorders is relatively difficult compared to other medical studies. It is because the cause of mental disorder is unclear relative to other medical diseases, various proximate causations are involved. And it is difficult to distinguish cause and effect and to carry out experimental research. Despite these methodological difficulties, it is possible to establish an evolutionary hypothesis on mental disorders based on constructive reductionism, and to demonstrate actual data on the model based on this hypothesis. In this paper, I will discuss some conceptual definitions needed for applying ecological approaches to evolutionary psychiatric research. We will first discuss the appropriate level of explanations and the scope of the study subjects, then discuss the conceptual definition of behaviour and function, dysfunction and the appropriate level of selection.

Osteochondroma is a common benign bone tumor, but relatively rare in the spine. Spinal osteochondroma originates mainly from the posterior column and sometimes invades the spinal canal causing cord compression and myelopathy. A 36-year-old man was admitted to the authors’ institution with a two-year history of neck pain. A radiology examination revealed osteochondroma, arising from the left superior articular process of the T1 vertebra with significant central canal narrowing. Most cases of the spinal osteochondroma originate in the cervical vertebra, but there are few reports of an origin of the cervicothoracic junction. This paper reports a case of osteochondroma at the cervicothoracic junction with a review of the relevant literature. [ABSTRACT FROM AUTHOR]

For the treatment of a bony Bankart lesion accompanied by an acute traumatic shoulder dislocation, anatomical reduction and stable fixation of the bone fragment and glenohumeral ligament are essential to avoid chronic instability or degenerative changes. If the Bankart lesion has large bony pieces or comminuted fragments, it can be difficult to perform precise and secure fixation of the big intraarticular fragment to the fracture site because of the limited visualization of the arthroscopic procedure. In addition, in the case of the open procedure, it requires an extensive surgical dissection to access the fractured fragment, which may cause surgical approach-related morbidity, such as neurovascular complications, delayed subscapularis healing, and increased risk of stiffness. This paper describes an alternative open suture anchor technique for a large bony Bankart lesion, which was secured anatomically with squared knots after a shuttle relay through bony tunnels and adjacent soft tissue and labrum. This technique can achieve anatomical and firm fixation under direct vision, and reduce the number of surgery related morbidities. [ABSTRACT FROM AUTHOR]

Slipped capital femoral epiphysis (SCFE) is a rare disorder of the proximal femur in adolescents. The pathogenesis of SCFE is unclear, but it is believed to be the result of a mechanical insufficiency of the proximal femur physis. SCFE appears to caused by mechanical, endocrinal, and immunological abnormalities. Few cases have reported the SCFE associated with endocrine disorder in the domestic literature, particularly in patients over 20 years old. This paper reports two cases of SCFE associated with hypopituitarism in adults over 20 years old. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper was to identify blood pressure, interdialytic weight gain, thirst and intradialytic discomfort in subjects after applying individual low-sodium dialysis fluid (1,2,3 mEq/L) to hemodialysis patients for 12 weeks. Methods: This study was a non-equivalent pre-post design. For 12 weeks, dialysate concentration was maintained at 1 mEq/L or 2 mEq/L or 3 mEq/L based on average sodium concentration of each individual, and the difference was compared after applying individually. Results: Change in blood pressure significantly decreased in the group where in pre-hemodialysis systolic pressure decreased the gradient of sodium concentration in serum sodium and dialysis solution by 2mEq/L. Interdialytic weight gain, and thirst showed significant decrease in all three groups. But in all three groups, intradialytic discomfort among dialysis showed no significant changes. Conclusion: Although application of low sodium dialysis fluid showed no change in intradialytic discomfort, lowered blood pressure, thirst, and interdialytic weight gain, which could be used for individual showing increased interdialytic weight gain and increased blood pressure. There is need for continued study on this. [ABSTRACT FROM AUTHOR]

This paper intended to address the issue of the protection of the donor's rights in the collection of residual human materials by medical institutions and the provision of them to the biobank under the ˹Bioethics & Safety Act˼ as amended in October 2019. In particular, we examined the procedural content issues regarding the adoption of the optout system, and also argued that the opt-in system was more appropriate. Of course, we agree that the medical institutions, which are intended to be amended by the law, will use the residual human materials for treatment and diagnosis purposes to lay the foundation for more efficient and active disease research for research purposes. In addition, the CIOMS guidelines stipulate that residual human materials can be stored and used in research, unless explicitly stated by the person who is the source of the residual human materials, and the conditions are set forth. That is opt-out system. However, the relevant details of the revised legislation suggest that the opt-out system, in which the residual human materials is donated to the biobank, unless the objector rejects it, will make it difficult for the informed consent to make integrated autonomous decisions. Because it is necessary to express the objection of rejection through the information received in writing, it is difficult for the patient to acknowledge that he has obtained enough information and understood and agreed to it. And, due to the subordinate hierarchical difficulties arising from the doctor-patient relationship, it is difficult to guarantee voluntary rejection of the donor. In addition, within three days after the human materials is collected, it is necessary to clarify the rejection of the offer, which is cumbersome and inconvenient to express the objection. Finally, privacy issues related to residual human materials may arise. Therefore, it is appropriate to adopt an opt-in system for protecting the donor's rights, which is more important than the effective progress of disease research and the result of excellent scientific results. First of all, we argued that sufficient training and information were required for the Institutional Review Board Member under consideration according to the revised law to work in consideration of this problems.

Skin plays important roles in protecting the internal organs from the chemical-biological risk factors and ultraviolet light. Exposure to the chemical and biological stimuli has a detrimental effect on skin's structure and physiological regulation. Therefore, much attention has been paid to natural products that show biological activities such as anti-oxidation, anti-aging and anti-bacterial activities. In this study, we investigated the skin-related biological activities of Oenothera lamarckiana aerial part extract. The extract contained 229.35 mg TAE (tannic acid equivalents)/g total polyphenolic compounds and the extract showed relative high antioxidant activity (SC50 value: 8.52 μg/mL). The IC50 value against tyrosinase and elastase were 307.94 and 181.51 μg/mL, respectively. This suggested that O. lamarckiana can be applied to whiten skin and slow the aging of skin. O. lamarckiana extract showed a growth inhibitory effect on Staphylococcu epidermidis (minimum inhibitory concentration: 250 μg/mL). Interestingly, O. lamarckiana extract showed no inhibitory effect on Pseudomonas aeruginosa on the paper disc assay. Yet the extract inhibited the growth of Pseudomonas aeruginosa on the broth dilution assay in a dose-dependent manners. Taken together, O. lamarckiana could have good potential for development as an additive in the cosmetic industry. [ABSTRACT FROM AUTHOR]

This paper provides data for product development and improvement of grape varieties by analyzing the satisfactionimportance of the grape selection attributes from a consumer's perspective. A survey was conducted on consumers aged 19- 59 living in Seoul, Gyeonggi and Incheon on their fruit consumption level, preferences according to the grape quality characteristics, importance, and satisfaction with the grape selection attributes. Three hundred and eighty two valid samples were collected and analyzed statistically using SPSS 23. In the preference according to the grape quality characteristics, consumers tended to prefer a sweet taste, black color, and seedless grapes. Regarding the importance of the grape selection attributes according to the level of grape consumption, the high consumption group considers texture, size, shape, color, ease of removing seeds, country of origin, area of production, certification, and brand to be more important. In satisfaction, the high consumption group rated satisfaction highly in texture, odor, size, shape, color, ease of removing peelings, ease of removing seeds, price, country of origin, area of production, certification, and brand. An analysis of the IPA of the grape selection attributes showed that improvement of price and shape attributes will be prioritized, and the development and management of properties, such as seeds, peelings, certification, and brand will be required. These results can be used to help improve the grape varieties and develop products that meet the consumer needs, secure the competitiveness of grape farmers, and revitalize the local economy.

This paper reviews the structural diagnosis of personality pathology based on Kernberg's object relations theory. It examines levels of integration of the five psychological structures such as 1) identity (sense of self and others), 2) major defense mechanisms (level of defensive operations), 3) reality testing, 4) quality of object relations, and 5) moral functioning. It is a diagnostic model that is especially valuable in identifying and differentiating the borderline personality organization (BPO). Patients organized at a low BPO level show severe identity pathology, splitting-based defenses, and unstable, highly affectively charged, polarized transferences, which significantly interfere with self-reflective capacity. For these reasons, it is suggested that psychoanalytic treatment should be modified to secure the therapeutic relationship and facilitate the integration of dissociated internal object relations in the here and now transference contexts..

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving the synovial membranes. Complete excision with a total synovectomy is important for diffuse type PVNS because of its high recurrence rate. In the ankle, complete excision of diffuse type PVNS is difficult due to the anatomical structure of the ankle joint. This paper reports the author's experience of surgical treatment with combined open and arthroscopic synovectomy. In this manner, it is expected that the complications of the open procedure and the recurrence rate of arthroscopic procedure can be reduced. [ABSTRACT FROM AUTHOR]

Carpal tunnel syndrome is rare in children. When it does occur in children, the most common causes reported are mucopolysaccharidosis and mucolipidosis. The median artery is a transitory vessel that develops from the axillary artery in early embryonic life and does not normally survive until postfetal life. In a small percentage of individuals, however, it persists into adulthood and is frequently accompanied by a bifid median nerve. A persistent median artery can be a cause of carpal tunnel syndrome in adults, but it is extremely rare in children and adolescents. This paper reports a case of a carpal tunnel syndrome caused by a persistent median artery and bifid median nerve in a 13-year-old girl. [ABSTRACT FROM AUTHOR]

The biomechanics study of the hip is aims to understand and explore the dynamic principles of weight transfer through the hip joint. This basic science knowledge can be applied in a variety of areas, including degenerative joint diseases and hip replacement arthroplasty. In particular, understanding of the biomechanics of the hip has led to the development of materials, design and fixation of implants, and it can be applied in various areas, such as the selection of surgical methods and the location of the implant. Moreover, it is essential to have good knowledge of the biomechanics of the hip to achieve better clinical results for patients. Therefore, this paper introduces the basic knowledge and biomechanical characteristics of a normal hip and hip replacement arthroplasty, which are needed to approach the biomechanics of the hip.

Lung cancer is the leading cause of death from cancer worldwide. The most effective way to reduce lung cancer mortality is early detection and treatment. Two large randomized controlled trials (RCTs), the National Lung Screening Trial and the Dutch-Belgian Randomized Lung Cancer Screening Trial, showed that low-dose CT (LDCT) can reduce the chances of lung cancer death. This paper reviews the two aforementioned RCTs and the current situations of implementing LDCT screening in several counties. Although nationwide programs of lung cancer screening are rare, they would increase in the near future. Using the two aforementioned RCTs and accumulating data from many counties, including the East Asian countries, a more effective way of LDCT screening in Korea can be devised and implemented.

Purpose: The purpose of this paper was to identify blood pressure, interdialytic weight gain, thirst and intradialytic discomfort in subjects after applying individual low-sodium dialysis fluid (1,2,3 mEq/L) to hemodialysis patients for 12 weeks. Methods: This study was a non-equivalent pre-post design. For 12 weeks, dialysate concentration was maintained at 1 mEq/L or 2 mEq/L or 3 mEq/L based on average sodium concentration of each individual, and the difference was compared after applying individually. Results: Change in blood pressure significantly decreased in the group where in pre-hemodialysis systolic pressure decreased the gradient of sodium concentration in serum sodium and dialysis solution by 2mEq/L. Interdialytic weight gain, and thirst showed significant decrease in all three groups. But in all three groups, intradialytic discomfort among dialysis showed no significant changes. Conclusion: Although application of low sodium dialysis fluid showed no change in intradialytic discomfort, lowered blood pressure, thirst, and interdialytic weight gain, which could be used for individual showing increased interdialytic weight gain and increased blood pressure. There is need for continued study on this. [ABSTRACT FROM AUTHOR]

Carpal tunnel syndrome (CTS) caused by pseudogout is an uncommon disease. The authors report a 65-year-old female who complained of sudden pain and neurological symptoms on her left hand. Surgical decompression was performed. In the histologic study, a calcium pyrophosphate dihydrate crystal deposit was confirmed. Her pain and neurological symptoms were relieved. Because CTS caused by pseudogout is rare, it is difficult to differentiate it from other diseases. This paper reports an uncommon case of CTS caused by pseudogout. [ABSTRACT FROM AUTHOR]

Purpose: In the treatment of Dupuytren’s contracture, the aim of optical treatment is to lower the recurrence rate and reduce complications. This paper reports the results of subtotal fasciectomy in Dupuytren’s contracture, extending the excision of palmar fascial structures from the diseased to normal appearing adjacent fascial structure. Materials and Methods: From 2007 to 2017, 45 patients with Dupuytren’s contracture treated by subtotal fasciectomy were reviewed retrospectively. The mean follow-up period was 45.9 months. Ninety-two digits were involved (index: 2, middle: 10, ring: 44, little: 36). The predisposing factors and affected joint were reviewed and the preoperative and postoperative contracture was measured. For clinical results, quick disabilities of the arm, shoulder, and hand (quick DASH) were used. Complications, including wound or skin problems, nerve injuries, hematoma, and complex regional pain syndrome, were assessed. Results: Preoperative flexion contracture was 43.2° in the proximal interphalangeal joint and 32.9° in the metacarpophalangeal joint. In nine cases, patients had residual contracture of 9.7° (range, 5°–20°) on average and if the total number of cases were included, the mean residual contracture was 2.3° on average. The quick DASH score at the 12 months follow-up was 12.4. The overall complication rate was 26.6%. Conclusion: Subtotal fasciectomy can be a good surgical treatment option for Dupuytren’s contracture with a low recurrence and low complication rate compared to other open procedures.

Artificial Intelligence (Al) born in 1956 is a general term that implies the use of a computer to make intelligent machines with minimal human intervention. Al is a topic dominating diverse discussions on the future of professional employment, change in the social standard and economic performance. In this paper, I describe fundamental concepts underlying Al and their significance to various fields including aviation and medicine. I highlight issues involved and describe the potential impacts and challenges to the industrial fields. While many benefits are expected in human life with Al integration, problems are needed to be identified and discussed with respect to ethical issues and the future roles of professionals and specialists for their wider application of Al.

The health of licence holders (flight crew members and air traffic controllers) is recognized as an important element of aviation safety. The medical emergency symptoms that occur during the flight duty period without prior notice can interfere with human performance capabilities and threaten aviation safety. To prevent this, ICAO has been required to conduct a periodic medical assessment process of licence holders including routine analysis of in-flight incapacitation events and medical findings during medical to identify areas of increased medical risk and continuous reevaluation of the medical assessment process to concentrate on identified areas of increased medical risk. The supply and demand of licence holders have become a major issue due to the increase in air traffic around the world, and the pilot retirement age has been extended to 65 years. But, there is no significant change in the aviation medical assessments process. The follow up of the result of medical examination discovered through aviation medical examination is a very important part, but it has not been properly implemented, and the sick leaves and medical inflight incapacitation reporting system should be improved. The management of health risk factors for licence holders must be implemented to prevent aircraft accidents or aviation safety problems caused by health problems. In this paper, we propose the development plan and concrete improvement plan of the health risk management system of licence holders in Korea in terms of aviation safety. [ABSTRACT FROM AUTHOR]

This paper interprets the work of Hans Bellmer, who took pictures after making a doll and distorting its form, and Diane Arbus, who took documentary photographs of unusual and marginalized people, as uncanny anxiety referred to by Freud. Through these two photographers' works, this paper examined how anxiety was used as an aesthetic strategy, and discussed the uncanny as an aesthetic experience. Uncanny refers to the phenomenon of familiar things being repressed and returning to their original place, or the phenomenon of familiarity being alienated due to repression. The aesthetic strategy of uncanny is used to bring a blind spot in reality that can be easily missed with an ordinary vision into the fore, by allowing for the slight shock to an appreciator. The ultimate goal of uncanny aesthetics is to promote both inner and external changes as well as to expand the scope of imagination, through freely crossing the borders between consciousness and unconsciousness, sympathy and antipathy, and reality and fiction.

Wheat is one of major crop and wheat flour is used to various end-use products such as bread, cookies and noodles due to its unique characteristic of it as elasticity and viscosity. Wheat consumption has been generally increasing in not only US and Europe but also Korea. Nevertheless, gluten proteins in wheat endosperm are cause of allergy by food ingestion. Hence, studies on the allergy have been conducting and have been attracting public attention. Herein, we report studies on research trend of the issue with research papers over the last decade for suggestion of future research direction. Since 2012, studies on allergy of gluten proteins have been dramatically increased based on the number of published papers related to the issue. As results of research activities by country, the Europe accounted for 60% corresponding to the number of papers. Next US (13%), Japan (9%), China (5%), and Korea (2%) came. In Korea, studies on allergy of gluten protein are less studied. In the field of studying of gluten allergy, there are two major technologies as preclinical technology and genome research accounted for 58% and 26%, respectively. In Korea, the study on glutenin proteins which is closely related to wheat allergy is actively performed. Therefore, it can be expected that research will be become more active.

An extremely rare accessory bone of the foot located in the distal portion of the navicular that articulates with the medial cuneiform was observed. Os paracuneiforme is usually located medial to the medial cuneiform or the naviculocuneiform joint. Although os paracuneiforme is often referred to as an accessory bone around the foot, few cases of this type of accessory bone have been reported. This paper reports a patient with a painful Os paracuneiform who underwent surgical excision of the accessory bone. [ABSTRACT FROM AUTHOR]

Causal reasoning is actively studied not only by psychologists but, in recent years, also by cognitive scientists taking the Bayesian approach. This paper seeks to provide an overview of the recent trends in causal reasoning research with a focus on the power probabilistic contrast theory of causality, a major psychological theory on causal inference. The power probabilistic contrast theory (PPCT) assumes that a cause is a power that initiates or inhibits the result. This power is purported be understood through statistical correlation under certain conditions. The paper examines the supporting empirical evidence in the development of PPCT. Also, introduced are the theoretical dispute between the PPCT and the model based on Bayesian approach, and the current developments and implications of research on causal invariance hypothesis, which states that cause operates identically regardless of the context. Recent studies have produced experimental results that cannot be readily explained by existing empirical approach. Therefore, these results call for serious examination of the power theory of causality by researchers in neighboring fields such as philosophy, statistics, and artificial intelligence.

This paper investigated monthly meal composition and type of foods prepared for Dalye (ancestor rituals) over a period of 1 year based on the records in Sakmangdalye-deungnok and reviewed the ingredients for Dalye foods. From the results of our survey, 19 to 20 dishes were served in Sakmangdalye. 24 to 25 different foods were served in Sakdalye. Foods for Sakdalye consisted of Silkwa, Jogwa-Gwapyun, Jeongkwa or Suksilkwa, Hwachae-Sujeonggwa, Tteok, Cho, Jeonyueo, Sugyuk, Jjim, Hwe, Po, Sikhye, Tang, main dish-Guksu or Mandu, and Jang. Ingredients used in Sakmangdalye were recorded in a very integrated and simple manner in Sakmangdalye-deungnok. All ingredients were categorized into three groups: Kwasil (Fruits), Byeongmisikseung (Rice cakes etc.), and Muyeok (purchases). Sakmangdalye-deungnok was helpful in consulting dishes and ordering ingredients when a table for Dalye was set. Moreover, it was written simply enough so those who were in charge of preparing food could easily understand. This paper establishes Sakmangdalye-deungnok as one of the key materials for Royal Cuisine. [ABSTRACT FROM AUTHOR]

In Vol. 31, No. 1, our journal prepared four review articles and two original papers. First, in commemoration of the 30th anniversary of our journal, the first review article described the history, development, and recent efforts for the qualitative improvement of the journal. For aviation workers, dizziness is an important disease that can interfere with their work. So, in the second review, we introduced guidelines that aviation medical examiners should be aware of in evaluating aviation workers who complain of dizziness. In the era of coronavirus disease 19 (COVID-19) pandemic, it is very important for aviation workers to get the vaccination safely and return to their work. So, Kwon introduced the latest updated guidelines for vaccination for aviation workers. In addition, Kim described the relationship between COVID-19 infection and respiratory allergic disease, and appropriate treatment guidelines. Lim investigated the recent trend of human papillomavirus vaccination for foreigners during the COVID-19 period, and investigated its implications. Finally, Ra developed various programs to strengthen students' global competencies and analyzed their satisfaction. [ABSTRACT FROM AUTHOR]

Anti-extractivist movements in Peru have been characterized as limited in scope and space, occurring mostly around high altitude Andes villages near the mining sites and in the middle of the rainforest. Though the extractive disputes have been numerous and persistent since 2000, numerous anti-extractivist movements could not expand beyond local boundaries, which is basically for two reasons. First, anti-mining movements could not build a nation-wide alliance network due to their lack of economic or environmental interests in common with other sectors and areas. Second, the political opportunity structure has been unfavourable to the small voices of the peasants from the remote and isolated mountain areas. While there could be many explanations for the weakness of anti-extractivist movements in Peru, this paper focuses on the political opportunity structure as the most relevant approach. I pay special attention to the reason anti-mining movement, it being the most prominent source of social conflict in Peru, and which proved to be unable to achieve any real change in the mining policy of the government. I focus on three main sources of political opportunity structure which were unfavourable to the anti-mining movement: 1) the authoritarian elite control of the state, 2) weak political institutions that disempower formal democracy, and 3) a weak civil society. More specifically, authoritarian exercise of the power by the state, the class nature of the neoliberal state, the fragmented party politics, an ineffective and weak democracy, a weak civil society, and the resulting lack of indigenous/peasant voices in Peru have resulted in closed opportunity for the required reform of the extractive sector. It would be necessary to develop a more democratic and responsive state and a more effective political party system with a more autonomous and mature civil society, in order to contribute to more effective policy reform, reduced socio-environmental conflicts and a more dynamic and stable economy in Peru.

Equine influenza (EI) is the main cause of respiratory illness in equines across the globe and is caused by equine influenza A virus (EIV-A), which has impacted the equine industry internationally because of the marginal mortality and high morbidity. In the present study, the immune responses after equine influenza vaccination were evaluated in 4,144 horses in Korea using the hemagglutination inhibition (HI) assay. The equine influenza virus (EIV), A/equine/South Africa/4/03 (H3N8), was used as the antigen in the HI assay. The mean seropositive rates were 89.2% (97.4% in 2016, 77.6% in 2017, and 92.4% in 2018). This paper highlights the advances in understanding the effects of vaccines and control strategies for mitigating the emerging menace by EIV [ABSTRACT FROM AUTHOR]

Urinary tract injuries occur in up to 10% of patients with abdominal trauma, and the kidney is the most commonly injured structure of the urinary system. The kidney is the third most common abdominal organ to be injured by trauma, following the spleen and liver, in that order. The American Association for the Surgery of Trauma kidney injury scale is the most commonly used classification system for blunt renal injuries, which grades renal injury based on the size of laceration and its proximity to the renal hilum on CT. CT aids in delineating the most important features of urological injury that affect the diagnosis and management, including interventions. The major renal injuries are usually surgical emergencies. The current trend toward a more conservative management of renal trauma and advances in interventional radiology in the field of trauma may increase the use of interventional procedures for patients with renal injury. Urethral injuries can be anterior or posterior depending on the injury site, and interventional urethral realignment plays an important role in the treatment of urethral injury and surgical repair or endoscopic urethral realignment. Therefore, in this paper, we provide a literature review and discuss the efficacy and clinical significance of intervention for urologic trauma. [ABSTRACT FROM AUTHOR]

In accordance with Article 15 of the Medical Service Act , medical personnel or a founder 「 」 of a medical institution may not, upon receiving a request for medical treatment or assistance in childbirth, refuse to render his/her service without ‘any justifiable ground’ in Korea. However, conscientious objection to abortion became a hot topic, as gynecologists who were unable to perform abortion in accordance with their religious and conscientious beliefs asked to recognize their right to veto after the Constitutional Court ruling on the punishment for abortion. It is forbidden to arbitrarily deny a medical provider a medical act. but conscientious and religious freedom of all people should be guaranteed. So it is also necessary to discuss the appropriateness of the range of conscientious objection for specific medical practices. As a based from the data, this paper summarizes the current status of the United States, Ireland, Italy, France, Germany, the United Kingdom and Canada, which guarantee the conscientious objection of medical providers to abortion in the form of medical law, special law and guidelines. And through this work, we have drawn up issues that require social consensus for domestic legalization. We hope that the discussion on conscientious objection to the realization of the rights of both the patient and the health care provider will be initiated through social consensus on these issues.
