The Japan Medical Association, a lobby of physicians, went on strike in July 1971 because of the medical reforms by the government. Although these physicians resigned as health insurance doctors, they continued to provide medical care and even health insurance treatment in some areas. This study uses the regional differences in resignation rates as a natural experiment to examine how the payment method of health insurance affects medical service utilization and health outcomes. Our estimation results indicate that if the participation rate of the strike increased by 1 percentage point and proxy claims were refused completely, the number of cases of insurance benefits and total amount of insurance benefits would decrease by 0.78% and 0.58%, respectively compared with the same month in the previous year. Moreover, the average amount of insurance benefits per claim increased since patients with relatively less serious diseases might have sought healthcare less often. Finally, our results suggest that the strike did not affect death rates in Japan.
Long noncoding RNA involvement in cancer
( Reo Maruyama ),( Hiromu Suzuki ) 생화학분자생물학회(구 한국생화학분자생물학회) 2012 BMB Reports Vol.45 No.11
Recent advances in genome and transcriptome analysis have enabled identification of numerous members of a new class of noncoding RNA, long noncoding RNA (lncRNA). lncRNAs are broadly defined as RNA molecules greater than 200 nt in length and lacking an open reading frame. Recent studies provide evidence that lncRNAs play central roles in a wide range of cellular processes through interaction with key component proteins in the gene regulatory system, and that alteration of their cell- or tissue-specific expression and/or their primary or secondary structures is thought to promote cell proliferation, invasion and metastasis. The biological and molecular characteristics of the large majority of lncRNAs remains unknown, and it is anticipated that improved understanding of the roles played by lncRNAs in cancer will lead to the development of novel biomarkers and effective therapeutic strategies.
Study on removal of microplastics using magnetic separation

In recent years, the impact of microplastics (MPs) on ecosystems is a serious problem. Since MPs are difficult to recover oncethey are dispersed into the environment, it is important to remove them at the source. We proposed a magnetic separation of primaryMPs (plastics manufactured in minute sizes) sized 10-100 μm that has not been removed in the sewage process, based on themagnetic seeding process. In this study, we used magnetite as a magnetic seeding agent, and conducted magnetic separationexperiments in the continuous process using a superconducting solenoidal magnet to investigate the feasibility of practical magneticseparation system of MPs. As a result, 85% separation rate was obtained by continuous separation using high gradient magneticseparation (HGMS) with hydrophobically treated magnetite as a magnetic seeding agent.

Background: The use of computed tomography (CT) device has increased in the past few decades in Japan. Dose optimization is strongly required in pediatric CT examinations, since there is concern that an unreasonably excessive medical radiation exposure might increase the risk of brain cancer and leukemia. To accelerate the process of dose optimization, continual assessment of the dose levels in actual hospitals and medical facilities is necessary. This study presents organ dose estimation using pediatric cerebral CT scans in the Kyushu region, Japan in 2012 and the web-based calculator, WAZA-ARI (https://waza-ari.nirs.qst.go.jp). Materials and Methods: We collected actual patient information and CT scan parameters from hospitals and medical facilities with more than 200 beds that perform pediatric CT in the Kyushu region, Japan through a questionnaire survey. To estimate the actual organ dose (brain dose, bone marrow dose, thyroid dose, lens dose), we divided the pediatric population into five age groups (0, 1, 5, 10, 15) based on body size, and inputted CT scan parameters into WAZA-ARI. Results and Discussion: Organ doses for each age group were obtained using WAZA-ARI. The brain dose, thyroid dose, and lens dose were the highest in the Age 0 group among the age groups, and the bone marrow and thyroid doses tended to decrease with increasing age groups. All organ doses showed differences among facilities, and this tendency was remarkable in the young group, especially in the Age 0 group. This study confirmed a difference of more than 10-fold in organ doses depending on the facility and CT scan parameters, even when the same CT device was used in the same age group. Conclusion: This study indicated that organ doses varied widely by age group, and also suggested that CT scan parameters are not optimized for children in some hospitals and medical facilities.

Currently in Japan, there are two difficulties in public facilities, plenty of facilities are becoming superannuated, and it will be difficult to renew them due to financial difficulties of municipalities. Under such circumstances, a lot of municipalities focus on compounding public facilities as a method for providing sustainable administrative services by increasing operational efficiency of them. In this paper, we clarified the actual situation and issues of composite public facilities from documentary and interview surveys to the five cases. From these surveys, it became clear that municipalities cannot obtain the operational efficiency of compounding unless they combine the facility functions across barriers and centralize operation by Public-Private Partnerships. Through these, we propose a management system for complex facilities that contributes to municipality finances.

Legal positivism and analytical jurisprudence projected law into a spere quite removed from living social reality; far above this reality soared the state, a metaphysical entity rather than a real fact. For legal positivism, of course, all sociology of law appeared as a crime towards the state and its order. The jurist in his ivory tower turned with contempt from all that had to do with the social reality of law. He was proud to argue in the formalistic vacuum of the sanctuary of the state, legislative texts and decisions of official tribunals which barred the road to all contact with the life of society. But the efficiency of law cannot be established by a simple interpretation and systematization of legislative texts and decisions of tribunals. Legal rules may remain entirely impotent, that is to say, with no application whatsoever, while decisions, may contradict each other. Tf the jurist took no account of the living law, of the spontaneous law inaction, of the flexible and dynamic law, of the behaviour, practices, of the institutions, of the beliefs related to law, be would run the danger of constructing an edifice entirely disconnected from the law really efficient in a given social milieu. A jurist in order really to concern himself with positive law rather than with formal logic. cannot detach his constructions from sociological research into the efficient law. Where an ever-widening gulf yawns between imported jural formulas and the traditional jural life, the sociology of law becomes a burning actuality. This is the case in Korea. Thus the democratization and modernization of the Korean jural life can no longer make a singl step without doing the work of a sociologist, without calling in the sociology of law. This article is a primary study of the sociology of law for the democratization of the Korean jurai life.
