This paper summarizes the genealogy of post-war Zainichi magazines in Japan until 1959 and examines their meaning in the context of magazine history in Japan. The purpose of this paper is to prepare the framework to view characteristics of Zainichi magazines in Japan after the war until the present from a continuous and comprehensive perspective. Zainichi, who were left behind in Japan after the war began to project diverse aspects of their lives onto magazines. Despite the poor publishing environment, censorship of GHQ, shortage of writers and financial limitations, the Zainichi society did not give up the public sphere of magazines. The confusion in this time period acted as an element to expose limitations of Zainichi magazines in Japan. Most of magazines published in 1940s and 50s had to focus on political propaganda within the political frame, and many of such magazines were only published for a short term. In other words, it is ambiguous to define the majority of them as 'magazines' and a considerable number of them cannot even confirm the existence, making it difficult to examine the whole picture of magazines from this period. However, recently excavated materials indicate that most of Zainichi magazines in Japan attempted to reflect the reality of the Zainichi society in various ways, though they were confined in the political frame. The process in which language of magazines was changed from Korean language to Japanese and then again to Korean language suggests that Zainichi magazines in Japan tried to consistently express their existence in 'ethnicity,' 'homeland' and beyond, mediated by 'politics' and 'culture.' Moreover, the experience of seeking for the possibility of Zainichi culture in Japan from the flow of cultural movements in Japan during 1950s is an experience of seeking for a popular 'expression' that overcomes the political conflict of homeland. This reveals the diversity the Zainichi society to occur afterwards. A more precise study on individual magazines published during this period would be necessary in the future.

This review paper provides a detailed analysis of PET (polyethylene terephthalate) bottle recycling in Japan. Japan is a global leader in PET bottle recycling due to its advanced regulatory framework and proactive industry initiatives. Japan's success attributes to the widespread adoption of bottle-to-bottle recycling, driven by the beverage industry's commitment to sustainability. By utilizing post-consumer PET bottle recovery and food-grade mechanical recycling technologies, Japan has achieved significant milestones in PET bottle recycling. This paper examines regulatory frameworks, collection systems, reprocessing facilities, and food safety assessments to highlight Japan's innovative approaches to PET bottle recycling and their impact on global sustainability efforts. Drawing parallels with Korea's early stages of PET recycling, it suggests involving major beverage companies and re-evaluating regulations to promote bottle-to-bottle recycling. The focus is on the implications for Korea to promote circular economy principles in plastic recycling.

본고는 일본 제국의 식민지 지배와 '전후보상'처리와 관련하여, 일본 제국주의와 조선 식민지, GHQ와 점령지 일본에서 이루어진 결재 과정과 이 과정에서 생산된 기록 원본의 출처를 밝히는 것을 목적으로 한다. 1910년부터 1952년까지를 대상으로 역사학과 기록학의 관점에서 분석하였다. 이 연구에서는 식민지 지배와 그 처리문제를 시공간적으로 연속선상에서 파악함으로써 제국과 식민지 점령지 기록에 대한 인식의 지평을 확대할 수 있는 기반을 마련하고자 하였다. 1910년부터 1945년까지 일제의 식민지 조선에 대한 강점지배에 대한 기록과 1945년부터 1952년까지 GHQ 점령기의 '전후보상'처리에 대한 결재원본은 한국, 일본, 미국 등에 분산 보존되어 있다. 가장 큰 원인은 일본제국정부와 조선총독부, GHQ와 일본종속정부의 결재구조에 있다. 즉, 중요정책, 인사, 예산에 대한 결재는 제국 본국에서 처리되고, 그 시행에 관한 결재는 식민지 및 종속국에서 처리되는, 상명하달식 이중결재구조 때문이다. 이에 따라 결재 원본도 일국에 완결적으로 보존되는 게 아니라 제국과 식민지 종속국가에 각각 분산 보존되어 상호 보완적 관계를 갖고 있다. 특히 최근 한일간 외교문제로 부각되고 있는 강제 동원된 조선인 미불금 문제는 GHQ의 정책결정과 일본정부의 정령 시행으로 공탁처리되어, '채무'에서 '경제협력'으로 둔갑해 버렸다. GHQ-일본의 상명하달식 결재시스템에 의해, '전후보상'을 위한 기본적인 원본기록 역시 미국과 일본에 각각 분산 보존 되게 되었다. 그러므로 1910년부터 1952년까지, 일제에 의한 식민지지배와 '전후보상'을 둘러싼 문제는 의사결정 프로세스와 기록의 출처 분석 등을 통해 시간적 공간적 측면에서 구조적 종합적으로 재인식될 필요성이 있다.

An appropriate post-polypectomy surveillance program requires the effectiveness of reducing colorectal cancer and safety. In addition, the post-polypectomy surveillance program should consider the burden of limited medical resource capacity, cost-effectiveness, and patient adherence. In this sense, a risk-stratified surveillance program based on baseline colonoscopy results is ideal. Major international guidelines for post-polypectomy surveillance, such as those from the European Union and the United States, have recommended risk-stratified surveillance programs. Both guidelines have recently been updated to better differentiate between high- and low-risk individuals. In both updated guidelines, more individuals have been downgraded to lower-risk groups that require less frequent or no surveillance. Furthermore, increased attention has been paid to the surveillance of patients who undergo serrated polyp removal. Previous guidelines in Japan did not clearly outline the risk stratification in post-polypectomy surveillance. However, the new colonoscopy screening and surveillance guidelines presented by the Japan Gastroenterological Endoscopy Society include a risk-stratified post-polectomy surveillance program. Further discussion and analysis of unresolved issues in this field, such as the optimal follow-up after the first surveillance, the upper age limit for surveillance, and the ideal method for improving adherence to surveillance guidelines, are warranted.

During the decades after the Fukushima Daiichi Nuclear Power Station (FDNPS) accident, ambient dose rates have markedly decreased when compared to those at the early state of the accident. Government projects have been continuously conducted by surveying the ambient dose rate and radiocesium distributions. Airborne surveys using crewed helicopters and unmanned aerial vehicles (UAVs) are the best methods for obtaining an overall picture of the distribution. However, ground-based surveys are required for accurate measurements near the population. The differences between these methods include the knowledge of the post depositional behavior of radionuclides in land use. The survey results form the basis for policy decisions such as lifting evacuation zones, decontamination, and other countermeasures. These surveys contain crucial findings regarding post-accident responses. This paper reviews the survey methods of government projects and current situation around the FDNPS. The visualization methods and databases of ambient dose rates are also reviewed to provide information to the population.

The liberated korea has the estimated population 16 million in 1945, and added 2.5 million just after an year. The korean repatriates returned by way of 2 main routes. The returnees, Wol-Nam-Min(former residents in north korea), and repatriates from Manchuria came into south korea over the 38th division line. The other repatriates from japanese islands and pacific areas came into Busan port and the vicinity. The repatriates who returned from the China and the Japanese islands made up about 80% of the total added population. However, the influx of overseas repatriates who explosively increased between 1945 and 1946, declined abruptly in April of 1946, and at last illegal re-emigration group to Manchuria and Japan Appeared, who had repatriated from those areas. This study deals with the "re-migration phenomenon of 1946" in korea, mainly focuses on 1) the motivation for those who decided to remigrate, their prospects of resettlement in Manchuria and post war japan after re-migration, 2) the structural problems of the Korean society in 1946-1947, and 3) the social recognition for the people who letf for Manchuria and Japan. This study proved the cause and background of re-migration phenomenon. The Manchuria case, the local authorities wanted farmers and peasants who could cultivate the abandoned land which had been originally pioneered and reclaimed by korean poor peasants, who repatriated to korean peninsula. On the other hand, the korean repatriates had a hard time in tenanting farmland, and so much difficulty in getting farming tools including fertilizer. That's why they left korea for Manchuria again. The Japanese case, the korean repatriates had a tough life owing to the restriction of properties left in japan, while the inflation and food shortage in korea got worse and worst. Accordingly, many koreans tried illegal entrance into post war japan. This study is a part of clarifying the universality and specificity of post war repatriation and migration issues developed in the south Korea. Through this study, we can find how difficult it is for newly liberated areas to accommodate repatriates and make them ordinary nationals in harmonic way with successful social integration. and we can observe the social aspect and administrative ability of newly liberated south korea in detail, Because the present korea has faced with so many problems connected with immigration workers and re-setting with korean communities abroad, we should introspect these historical experience of our own.

Background: Postoperative pain management is crucial for patients undergoing total knee arthroplasty (TKA). There have been many recent clinical trials on post-TKA peripheral nerve block; however, they have reported inconsistent findings. In this meta-analysis, we aimed to comprehensively analyze studies on post-TKA analgesia to provide evidence-based clinical suggestions. Methods: We performed a computer-based query of PubMed, Embase, the Cochrane Library, and the Web of Science to retrieve related articles using neurothe following search terms: nerve block, nerve blockade, chemodenervation, chemical neurolysis, peridural block, epidural anesthesia, extradural anesthesia, total knee arthroplasty, total knee replacement, partial knee replacement, and others. After quality evaluation and data extraction, we analyzed the complications, visual analogue scale (VAS) score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Evidence was rated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Results: We included 16 randomized controlled trials involving 981 patients (511 receiving peripheral nerve block and 470 receiving epidural block) in the final analysis. Compared with an epidural block, a peripheral nerve block significantly reduced complications. There were no significant between-group differences in the postoperative VAS score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Conclusions: Our findings demonstrate that the peripheral nerve block is superior to the epidural block in reducing complications without compromising the analgesic effect and patient satisfaction. Therefore, a peripheral nerve block is a safe and effective postoperative analgesic method with encouraging clinical prospects.

The purpose of this study was to evaluate the effects of method for construction of cast post and type of dental cement on the retention of cast post. The wax patterns or Duralay resin patterns were used for construction of cast post. The dental cements used in this study were zinc phosphate cement(Fleck's zinc cement, Mizzy INc., U.S.A.), glass ionomer cement(Fuji I, G-C Co., Japan), and resin cement(Panavia-EX, Kuraray Co., Japan) and the retention of cast post was measured with Instron Universal Test Machine(Instron Engineering Co., U.S.A.). The obtained results were as follows : 1. The tensile bond strength of cast posts made by Duralay resin patterns revealed 39.13(kg) with Panavia-EX, 46.40(kg) with phosphate cement, and 37.78(kg) with glass ionomer cement. 2. The tensile bond strength of cast posts made by wax patterns revealed 39.25(kg) with Panavia, EX, 44.12(kg) with phosphate cement, and 40.23(kg) with glass ionomer cement. 3. The tensile bond strength of cast posts made by Duralay resin patterns or wax patterns were not affected by the type of dental cements(P>0.05).

The purpose of this study was to analyze the changes and characteristics of street fashion in Japan of the 1980s. The data were collected from the Mainichi Newspaper published in Japan from 1950 to 1990. The results were as follows: 1. After world war II, the street fashion had changed through the styles of the Panpan, Apres, Miyuki, Hippie & Hooten, Bikers in Japan. 2. The 1980s was characterized as an era of post industrial society and the appearance of Shinjinrui which means new human. In street fashion, these changes led to greater focus on unique style in Japan. In the 1980s, the street fashion had developed within four styles : traditional casual wear style, American sports wear style, performance.oriented style, and Japanese DC brand style in Japan.
