The article discusses the study which aims to determine the shear bond strength for ceramic abutment CerAdapt treated by tribochemical coating of ROCATEC system and alumina sandblasting. In the process, the surface of CerAdapt was sandblasted by ROCATEC to clean the surface for 10 seconds and another 15 seconds with special silica and silica coating alumina. Thus, the study found that tribochemical coating of the ROCATEC system dominated against alumina sandblasting in shear bond strength.

The health and welfare of the Japanese people were of a lower standard compared to other developed countries at the end of the World War II in 1945. Crawford F. Sams, Chief, the Public Health and Welfare Section of the Supreme Commander for the Allied Powers thought that medical care in a wartom country could be improved not by building new hospitals and providing more medical equipment, but through professional education and training. He founded the Council on Medical Education to reform the Japanese medical education. The Council shaped Japanese medical education by establishing the standards for medical school education and initiating internship and a national medical licensure examination. In the early 1950s, the Unitarian Service Committee Medical Mission was invited to teach to medical school professors and students American medicine. This medical mission was also a contribution of the Public Health and Welfare Section to Japanese medical education. This article explores how Public Health and Welfare Section played vital roles in transforming Japanese medical education and postgraduate training during the occupation.

In early 1946, immediately after World War II, there was a smallpox epidemic in Japan. In this paper we investigated trends in the occurrence of smallpox by week and region using official documents of the General Headquarters, Supreme Commander for the Allied Powers (GHQ/SCAP), which are stored in the National Diet Library Modern Japanese Political History Materials Room, and summarized the measures taken against this epidemic. The following two points were clarified: 1) The 1946 smallpox epidemic peaked in Week 13 (March 24-30; 1,405 new patients), and the highest morbidity during this epidemic was seen in Hyogo Prefecture, followed by Osaka Prefecture, Aichi Prefecture, Tokyo Prefecture, and Hokkaido Prefecture. 2) Measures taken against this epidemic were classified into the following three stages: 1. "Vaccine shortage/Manufacture acceleration stage," 2. "Vaccine sufficiency/Smallpox vaccination program implementation stage," and 3. "Detection of defects in vaccination technique/Reimplementation of the smallpox vaccination program stage".

Immediately after World War II, malaria became one of the major infectious disease threats in Japan. The prevalence of malaria was high in all regions in the summer of 1946. In most prefectures, the prevalence decreased with time thereafter and virtually no epidemics occurred after 1947. Shiga Prefecture, however, was an exception to this pattern. The epidemics in the prefecture occurred repeatedly until 1949, and the prevalence rapidly decreased in 1950. While the epidemics in most prefectures were caused by "imported malaria," those in Shiga Prefecture were caused by "indigenous malaria." This paper focuses on the eradication campaign of "endemic" malaria in Hikone City, Shiga prefecture after WWII. The city government began the campaign in April 1949. They established a malaria research institute for developing and implementing plans. The widespread spraying of insecticides such as DDT was implemented throughout the city and the moat around Hikone Castle was filled in, in order to reduce the mosquito population. Residents also cooperated extensively with programs for sanitation and health education. As a result of these efforts, malaria was completely eliminated in the city within six years. Malaria is still a life-threatening illness for many people in tropical areas of the world. Hikone's postwar experience could provide important lessons for malaria control programs in many places.

Objectives: The objective of this study was to elucidate the condition of malaria epidemics during the postwar Occupation period in Japan., Methods: The statistical records listed in the appendices of the "Weekly Bulletin", an official document of the General Headquarters, Supreme Commander for the Allied Powers (GHQ/SCAP) that is currently kept in the National Diet Library Modern Japanese Political History Materials Room, were converted into electronic files. On the basis of these records, the monthly prevalence of malaria was plotted in graphs to analyze the course of epidemics with respect to time and place., Results: The prevalence was high in all regions in the summer of 1946, when the present records were initiated. As a general trend, the prevalence was high in western Japan and low in eastern Japan. In all regions except the Kinki region, the prevalence decreased with time thereafter and virtually no epidemics occurred after 1948. In the Kinki region, epidemics with a prevalence of over 70 cases per 100,000 individuals repeatedly occurred until 1949, but the prevalence rapidly decreased in 1950. By prefecture, Saga Prefecture showed the highest prevalence in the nation in July 1946. While the prevalence in most prefectures decreased with time, Shiga Prefecture was the only prefecture with recurring epidemics with a prevalence of over 800 cases per 100,000 individuals until 1949., Conclusions: Malaria epidemics during the Occupation were classified into epidemics caused by "imported malaria", which was observed in many prefectures, and those caused by "indigenous malaria", which was observed only in Shiga Prefecture.

Japan's health statistics system, considered among the best in the world today, continually complies and organizes information about various infectious diseases. However, systematic surveillance was not conducted by the Ministry of Health and Welfare between World War II and the postwar period, creating a gap in health data. In contrast, the GHQ/SCAP/PHW. which was closely involved in health and medical reform during the Occupation, thoroughly investigated the health conditions of the Japanese people during this period. This article describes the trends in acute infectious diseases in Occupied Japan by using statistical records listed in the appendices of the "Weekly Bulletin", an official document of the GHQ/SCAP that is currently kept in the National Diet Library Modern Japanese Political History Materials Room.
