The “Industrial Internet of things” (IIoT) has rapidly become a popular concept. However, the IIoT concept has caused problems in managing consistent identifiers. To solve these problems in control system management, we propose Structured ID, which can define the complicated structure of control systems using IDs on a tree structure, and relational links, which can describe meaning for subsets of structured IDs. Furthermore, in use cases that utilize consistently managed information, a method of distributing appropriate information to each stakeholder is required. To address this requirement, we propose an orthogonal information retrieval technique for Structured ID. Finally, we evaluate that the proposed techniques can be implemented using web technology and confirmed that those can solve problems in the Industrial Internet of things use case.

This report details business development by Nakagawa Jyuken Corp, which targets the renovation of Kominka in the Kameoka and Nantan city areas of Kyoto Prefecture. Its aim is focused on the growth and revitalization of the regional economy. The company has created a systematic business model, based on experience and know-how, for real estate companies and home builders nationwide. If this program is successful, it could lead to the utilization of vacant houses, as vacant housing is forecasted to dramatically increase in the future. I would like to introduce Nakagawa Jyuken’s business model from a viewpoint that allows it to be seen as the first step toward resolving the vacant housing problem in Japan.

This paper takes Utsunomiya City, Tochigi Prefecture, as a case study and, using the exhaustive investigation of vacant housing in the city, describes the distribution of vacant housing within the city and explains its causes. As a result, it has been confirmed that the number and percentage of vacant houses in Utsunomiya City is increasing. This is because along with the widespread use of private cars, the suburbs are becoming centres for living and employment in local cities. Conversely, the city centre is losing its appeal as a place to live and work in. People living in the city centre use cars to drive to the suburbs in order to buy groceries. As the suburbs prosper, the city centre loses its charm, accelerating the increase in vacant housing in built-up areas. The increase of vacant housing in built-up areas is hollowing the city centre and its surrounds. The city is decaying from its core. This is the problem of local city vacant housing.

本稿は，1960年代・1970年代にスプロールを伴って形成された小規模開発住宅地に着目し，住民の転出入から，これらの住宅地が郊外に立地する住宅地の中でどのような位置づけにあったのか，どのような役割を果たしていたのかを，戦後日本の住宅事情や社会・経済情勢から明らかにした．対象地域の埼玉県富士見市関沢地区は，1970年前後を中心とした中小ディベロッパーによる小規模開発・狭小敷地の建売住宅開発が連担し形成された住宅地である．関沢地区では，開発が始まる1960年代中頃から1980年代前半まで20代・30代を中心とする若年ファミリーが多く居住し，活発な転出入がみられた．居住者の多くは東京区部から転入し，数年で比較的近隣のより敷地規模の広い戸建住宅へ転出していった．しかし1980年代中頃から，関沢地区の戸建住宅では建替えが進み，活発な転出入がみられなくなり滞留傾向が強まる．このことから1960年代後半から1980年代前半における関沢地区の狭小な戸建住宅は若年層の仮の住まいとしてその役割を果たしていたと考えられる．そして関沢地区の戸建住宅において居住者の活発な入替えがあった背景は，第1にバブル崩壊までの持続的な地価や賃金の上昇，第2に家族向け賃貸住宅の不足，そして第3に分譲マンションが一般化していなかったことがあげられる．このことから，当地域にみられた狭小な戸建住宅は，当時の社会・経済情勢が投影された時代の産物であったといえる．

Increasing synchronization performance is one of the most important factors for improving Java performance. We present the concept of quasi-immutable objects and its application to implement fast synchronization primitives. Quasi-immutable objects are usually used for read accesses, but they are rarely used for write accesses. Using these characteristics, we describe the optimization for a synchronized read sequence of quasi-immutable objects. Our described method dynamically detects objects that are not written from critical sections of other threads, and applies the fast read sequence. The optimized read sequence enables the simultaneous execution of critical sections by multiple threads and reduces synchronization overhead. We implemented the described optimization on HotSpot Java VM. The experimental evaluations indicated that the optimization improved the performance of a micro-benchmark up to a factor of 16 and SPEC benchmarks up to 31%.

We experienced an operated case of pseudocyst of the pancreas which arised in the stump after resection of tail of the pancreas. A 74-year-old man, who had undergone resection of tail of the pancreas for a cancer of it 2 years before, visited our hospital with the chief complaints of an abdominal tumor, nausea and vomiting. The patient had mild inflammatory findings such as CRP of 4.0 and WBC of around 10, 000. From abdominal ultrasonography and abdominal CT findings, the patient was diagnosed as having a 6×6 cm pseudocyst of the pancreas. Anastomosis, stomach to cyst by transgastric approach, was carried out. On the 40th day after surgery the cyst disappeared.

This paper describes a parallel associative processor, lXM2, developed mainly for semantic network processing. IXM2 consists of 64 associative processors and 9 network processors, having a total of 256K words of associative memory. The large associative memory enables 65,536 semantic network nodes to be processed in parallel and reduces the order of algorithmic complexity to O( 1) in,basic semantic net operations. It is shown that IXM2 has computing power comparable to that of a Connection Machine. Programming for lXM2 is performed with the knowledge representation language IXL, a superset of Prolog, so that IXM2 can be utilized as a back-end to AI workstations.

In a nationwide study conducted in 11 surgical institutions of C-425, a newly developed human native immunoglobulin liquid preparation for intravenous injection, was combined with conventional antibiotic treatment to investigate the efficacy and safety. A total of 47 patients with severe infections which had not symptomatically responded to 3-day or longer treatment with any antibiotics was included. Doctors in charge judged the efficacy of C-425 to be "excellent" in 3 patients, "good" in 13, "fair" in 15, and "poor" in 4. Thus, a total of 16 patients (45.7%) was judged to have responded to C-425 when the "excellent" and "good" responses were combined. The number responding was 31 (88.6%) when the "fair" cases were also included. Excluding 31 patients who did not meet the Committee's criteria, the Committee judged the efficacy of C-425 in a total of 16 patients; the efficacy was "excellent" in 2 patients, "good" in 4, "fair" in 9, and "poor" in 1. The number of responding patients was 6 (37.5%) of the 16 when the "excellent" and "good" cases were combined, and 15 (93.8%) when the "fair" cases were added. Bacteriological assessment was conducted in a total of 9 patients. Causative bacteria were eradicated in 3 patients, decreased in number in 1, replaced in 2, and persisted in 3. Thus, bacteriological efficacy was observed in 6 of the 9 patients (66.7%). Neither adverse reactions nor drug-related laboratory abnormalities were observed in the 47 patients.

The patient, a 25-year-old man, had received a stab wound to the left anterior chest with a kitchen knife and was transported to our center. As plane chest roentgenography showed left hemothorax and his blood pressure was decreased, thoracotomy was urgently carried out. An approximatoly 3cm stab wound was recognized on the left side of the anterior descending branch of the left coronary artery, and hemostasis was performed by 4-acus interrupted suture using 3-0 Ticron® thread. Although the postoperative blood circulation was stable, ECG and enzymological examination showed suspicion of myocardial infarction and coronary arteriography showed occlusion of the anterior descending branch of the left coronary artery. Furthermore, left ventricular arteriography showed anteroseptal dyskinesis and ventricular aneurysmal changes. The patient is uneventfully under observation of the course. In the present case, the thrombotic occlusion and so on, which were caused by direct ligation of the coronary artery with suture thread or distortion or flexion of the coronary artery with ligature were considered to be the cause of ventricular aneurysm formation. With regard to the indication for surgery, the procedure for ventricular aneurysm after myocardial infarction is though to be applied to this case.
