Abstract

Hyper-Kamiokande consists of two identical water-Cherenkov detectors of total 520~kt with the first one in Japan at 295~km from the J-PARC neutrino beam with 2.5$^{\textrm{o}}$ Off-Axis Angles (OAAs), and the second one possibly in Korea in a later stage. Having the second detector in Korea would benefit almost all areas of neutrino oscillation physics mainly due to longer baselines. There are several candidate sites in Korea with baselines of 1,000$\sim$1,300~km and OAAs of 1$^{\textrm{o}}$$\sim$3$^{\textrm{o}}$. We conducted sensitivity studies on neutrino oscillation physics for a second detector, either in Japan (JD $\times$ 2) or Korea (JD + KD) and compared the results with a single detector in Japan. Leptonic CP violation sensitivity is improved especially when the CP is non-maximally violated. The larger matter effect at Korean candidate sites significantly enhances sensitivities to non-standard interactions of neutrinos and mass ordering determination. Current studies indicate the best sensitivity is obtained at Mt. Bisul (1,088~km baseline, $1.3^\circ$ OAA). Thanks to a larger (1,000~m) overburden than the first detector site, clear improvements to sensitivities for solar and supernova relic neutrino searches are expected., Comment: 102 pages, 49 figures.

Abstract

Hyper-Kamiokande consists of two identical water-Cherenkov detectors of total 520 kt, with the first one in Japan at 295 km from the J-PARC neutrino beam with 2.5 off-axis angles (OAAs), and the second one possibly in Korea at a later stage. Having the second detector in Korea would benefit almost all areas of neutrino oscillation physics, mainly due to longer baselines. There are several candidate sites in Korea with baselines of 1000–1300 km and OAAs of 1–3. We conducted sensitivity studies on neutrino oscillation physics for a second detector, either in Japan (JD 2) or Korea (JD + KD), and compared the results with a single detector in Japan. Leptonic charge–parity (CP) symmetry violation sensitivity is improved, especially when the CP is non-maximally violated. The larger matter effect at Korean candidate sites significantly enhances sensitivities to non-standard interactions of neutrinos and mass ordering determination. Current studies indicate the best sensitivity is obtained at Mt. Bisul (1088 km baseline, OAA). Thanks to a larger (1000 m) overburden than the first detector site, clear improvements to sensitivities for solar and supernova relic neutrino searches are expected.

Abstract

Hyper-Kamiokande consists of two identical water-Cherenkov detectors of total 520 kt, with the first one in Japan at 295 km from the J-PARC neutrino beam with 2.5∘ off-axis angles (OAAs), and the second one possibly in Korea at a later stage. Having the second detector in Korea would benefit almost all areas of neutrino oscillation physics, mainly due to longer baselines. There are several candidate sites in Korea with baselines of 1000–1300 km and OAAs of 1∘–3∘⁠. We conducted sensitivity studies on neutrino oscillation physics for a second detector, either in Japan (JD × 2) or Korea (JD + KD), and compared the results with a single detector in Japan. Leptonic charge–parity (CP) symmetry violation sensitivity is improved, especially when the CP is non-maximally violated. The larger matter effect at Korean candidate sites significantly enhances sensitivities to non-standard interactions of neutrinos and mass ordering determination. Current studies indicate the best sensitivity is obtained at Mt. Bisul (1088 km baseline, 1.3∘ OAA). Thanks to a larger (1000 m) overburden than the first detector site, clear improvements to sensitivities for solar and supernova relic neutrino searches are expected.

Abstract

This study was undertaken to determine the effects of occupation, lifestyle and the genetic polymorphisms of cytochrome P450 1A1 (CYP1A1), cytochrome P450 2E1 (CYP2E1) and glutathione S-transferases micro1 (GSTM1) and 1 (GSTT1) on the concentrations of urinary 1-hydroxypyrene (1-OHP) and 2-naphthol among Korean coke oven workers and university students. The study subjects included 90 coke oven workers and 128 university students. A questionnaire was used to obtain detailed data about the work area, smoking habits and food intake of subjects. Associations between urinary polycyclic aromatic hydrocarbon (PAH) concentrations and occupation, smoking status, total airborne PAH level and genetic polymorphisms were tested. Urinary 1-OHP and 2-naphthol concentrations were higher in coke oven workers than in students and correlated significantly with work area. Urinary 2-naphthol concentrations increased with an increase in the level of cigarette smoking in students. Total airborne PAH level correlated with urinary 1-OHP concentration in coke oven workers. Urinary 1-OHP and 2-naphthol concentrations were higher in coke oven workers with the c1/c2 or c2/c2 genotype of CYP2E1 than in those with the c1/c1 genotype. Urinary 2-naphthol concentrations were higher in GSTM1-null workers than in GSTM1-positive workers. In multiple regression analysis CYP2E1 was a significant factor determining urinary 1-OHP concentrations in coke oven workers. CYP2E1 and GSTM1 were significant determinants for urinary 2-naphthol concentrations in coke oven workers and GSTM1 and smoking were prognosticators among university students. Urinary 1-OHP is a better indicator of occupational exposure to PAH in coke oven workers than 2-naphthol, whereas urinary 2-naphthol may be more sensitive for non-occupational inhalation exposure to PAH. In occupationally exposed populations CYP2E1 and GSTM1 appear to play an important role in the metabolism of pyrene and naphthalene. In individuals not occupationally exposed to PAHs GSTM1 and smoking seem to influence the urinary concentration of 2-naphthol.

Abstract

Background: There is a dearth of literature evaluating the accuracy of Air Displacement Plethysmography (ADP) compared to Dual-energy X-ray Absorptiometry (DXA) for assessing body composition in individuals with lower limb amputations. Validity of ADP in persons with lower limb amputations must be established., Objective: The objective of this study was to compare body composition in persons with lower limb amputations using the BOD POD ® and DXA., Methodology: Body composition was performed on eleven lower limb prosthesis users (age 53.2±14.3 years, weight 81.9±22.3kg) using ADP and DXA with and without prosthesis., Findings: Repeated measures ANOVA indicated no significant difference in body composition among and between trials, F(3,8)= 3.36, p= 0.075. There were no significant differences in Body Fat (BF) percentage with and without prostheses on the BOD POD (28.5±15.7% and 33.7±12.1%, respectively) nor the DXA (32.9±10.6% and 32.0±9.9%, respectively). Association between the BOD POD and DXA were greatest when prostheses were not worn compared to when they were worn. Bland-Altman plots indicate agreement between BOD POD ® and DXA was greatest while wearing the prosthesis., Conclusion: This study is a first to compare total body fat percent between the BOD POD ® and DXA in lower limb prosthesis users. BOD POD ® report valid indices of BF%. Future work will utilize the BOD POD ® in intervention studies for monitoring body composition changes across the continuum of rehabilitation., Competing Interests: The authors declare no financial and personal relationships with organizations or individuals that might have influenced their research., (Copyright (c) 2023 Smith JD, Guerra G, Symons TB, Kwon EH, Yoon EJ.)

Abstract

Food samples are collected nationwide from January 2016 to February 2017 and their contents of artificial radionuclides are measured to address the growing concerns regarding the radioactive contamination of food products in Korea. Specifically, 900 food samples are collected for this study and their contents of representative artificial radionuclides 134 Cs, 137 Cs, 239,240 Pu, and 90 Sr are analyzed. The analysis shows that the activity concentrations of 137 Cs in fish range from minimum detectable activity (MDA) to 340 mBq/kg of fresh weight. The concentration factor (CF) determined for 137 Cs as a measure of its bioavailability is calculated to be ca. 74 and found to be very similar to that (100) recommended by the International Atomic Energy Agency. With an MDA of <0.221 mBq/kg, the results reveal that 239,240 Pu values in fish are below the MDA. The activity concentrations of 137 Cs and 90 Sr are lower than the MDA in both shellfish and seaweed, while the activity concentrations of 239,240 Pu in shellfish range from 0.26 to 2.18 mBq/kg, and for seaweed samples range from 2.07 to 3.38 mBq/kg. The atom ratios of 240 Pu/ 239 Pu in shellfish caught at the Korean coast vary from 0.209 to 0.237, with a mean of 0.227. The higher 240 Pu/ 239 Pu atom ratio determined in shellfish is thought to be caused by the plutonium transported from the Pacific Proving Grounds rather than other sources such as the Fukushima nuclear power plant accident. The activity concentrations of 137 Cs in mushrooms are found to vary from 1.0 to 21.4 Bq/kg, with the highest concentrations observed in the Oak (shiitake) and Sarcodon asparatus. 134 Cs is detected in three mushroom specimens collected from Jeju Island and about 3-3.6% of 137 Cs present in the wild mushrooms native to the Jeju Island are introduced as a result of the Fukushima nuclear plant accident. The annual effective doses of 137 Cs received through consumption of mushrooms and fish are 2.0 × 10 -4  mSv yr -1 and 3.9 × 10 -5 mSv yr -1 , and those values are negligible compared to the annual effective doses limit of 1 mSv yr -1 ., (Copyright © 2018 Elsevier Ltd.

Abstract

Plasminogen activators (PAs), commonly found on the membrane of spermatozoa, convert plasminogen into plasmin and may participate in mammalian fertilization. Correlations have been reported between reactive oxygen species (ROS) and spermatozoa function, although the relationship between PA activity and ROS is unknown. We investigated the effects of ROS on PA activity. We used an in vitro model of free radical generation whereby boar spermatozoa were preincubated in xanthine and xanthine oxidase (X-XO) and PA activity was then measured. The acrosome reaction of boar spermatozoa was significantly promoted by 100 mU/mL plasmin (P<0.01), similar to levels achieved when stimulated with the positive calcium (2 mM) control. The addition of plasminogen to the fertilization medium significantly promoted both spermatozoa binding (157.5+/-14.0 spermatozoa/oocyte) and the percentage of oocytes with a male pronucleus (74.5+/-6.4%) compared with control (98.4+/-21.8 spermatozoa/oocyte and 51.4+/-5.3%, respectively; P<0.05). The acrosome reactions of spermatozoa were significantly higher when incubated with calcium (2 mM; 60.2+/-2.7%), calcium (2 mM)+EDTA (6 mM; 29.4+/-4.2%), sodium nitroprusside (0.1 microM; 38.0+/-4.2%), H(2)O(2) (100 microM; 56.0+/-3.0%), and X-XO (0.5 mM and 0.05 U/mL, respectively; 31.8+/-3.7%) compared with non-capacitation medium as control (19.0+/-2.7%; P<0.05). However, when spermatozoa were incubated with only X-XO, PA activity was significantly higher than with other treatments (P<0.05). Moreover, the addition of the antioxidant superoxide dismutase to the X-XO system significantly blocked the PA activity of spermatozoa (P<0.05). The PA activity of spermatozoa treated with X-XO was significantly reduced by the addition of MEK inhibitor (55.2+/-5.6 ng/mL) and p38 inhibitor (57.4+/-2.7 ng/mL), but not PI3K inhibitor, compared to the control (X-XO; 68.0+/-5.8 ng/mL; P<0.05). The induction of PA activity in boar spermatozoa by free radical generation suggests the PA/plasmin system plays a role in mammalian fertilization.
