Malaria remains a global health threat. Approximately 97% of the population is at risk in sub-Saharan countries, particularly Nigeria. This study compared the performance of 2 diagnostic methods in assessing malaria endemicity in the rural communities of Ebonyi State, Nigeria. A total of 1,140 study participants were screened for malaria parasite using Rapid Diagnostic Test kits (RDT) in the field, while thick and thin films for microscopy were examined in the laboratory. Our result showed that malaria prevalence was 56.8 by RDT and 38.6% by microscopic test. Age group under 10 years had the highest prevalence of 28.9% (RDT) and 23.6% (microscopy), respectively. The highest prevalence of 19.5% by RDT was recorded in Onicha Local Government Area, while the highest prevalence of 13.4% with microscopy was recorded in Ezza North Local Government Area. The sensitivity and specificity of microscopic examination were both 100%, while those of RDT were 95.5% and 75.9%, respectively.

개항 후 1883년에 원산학사가 설립되고, 1894년에는 갑오개혁으로 여러 가지 교육개혁이 시행되었다. 1895년 한성사범학교 관제를 시작으로 각종학교 관제의 교육과정에 과학 교과가 등장하면서 과학 교과서의 필요성이 대두되었다. 정부는 필요한 교과서률 편찬하는 한편 여러 가지 학교관련 법령을 통하여 교과서의 사용에 관한 규정을 정하였다. 1895년 소학교령에서는 "교과용서(敎科用書)는 학부(學部)의 편집(編輯)한 외(外)에도 혹학부대신(或學部大臣)의 검정(檢定)을 경(經)한 자(者)를 용(用)함"으로 규정하였고, 1906년 보통학교령에서는 "교과서(敎科書)는 학부(學部)에서 편찬(編贊)한 것과 밋 학부대신(學部大臣)의 인가(認可)를 경(經)한 것으로 함"으로 규정하였다. 이에 따르면 각급 학교에서 사용할 수 있는 교과서는 학부에서 편찬한 것이거나 학부대신의 검정을 받은 것 또는 인가를 받은 것으로 제한되었다. 교과서에 관한 정책은 1906년 일본인이 학부에 참여하면서 1908년부터 본격적으로 수행되었고, 이것은 1910년 한일합방을 위한 식민지 교육정책과 밀접하게 수행되었다고 볼 수 있다. 특히 1908년의 사립 학교령과 교과용도서검정규정, 그리고 1909년의 출판법은 교과서를 통제하는 주요 수단이었다. 한국에서 발행된 62종의 과학 교과서 중 사용금지를 당한 것은 18종인데 2종은 불인가, 13종온 검정무효 그리고 3종은 검정 무효 및 검정불허가 처분을 중복으로 받았다. 이는 과학 교과가 학부나 총독부의 검열로부터 다른 교과에 비해 상대적으로 자유로운 편이었지만 일제가 점차 교과서 통제를 강화하면서 과학 교과서에도 통제를 가하고 있었음을 나타내는 것이다.

Workers' periodic health examination is the main tools used to manage the health problems of most workers in Korea. The most common health problem found in workers' periodic health examination is liver disorder. Liver disorder is also one of the most common health problems in general population and one of the leading causes of mortality in adult population. Regulation proposed by government (No. 207, Ministry of Labor, 1992) defines the criteria for selection of workers with the liver dysfunction for further evaluative examination and the examination items used for diagnosis of the workers with liver dysfunction. This study was designed to evaluate the proficiency of each examination items presently defined in Regulation and propose the optimal examination items for detection of the liver disorders found by workers' periodic health examination. Study subjects are 186 workers with abnormal liver function tests in screening examination of workers' periodic health examination. Questionnaire survey including past history of liver disorder, drinking history, height and weight was done. Physical examination by physician, routine test items defined by Regulation (SGOT, SGPT, $\gamma$-GTP, protein, albumin, total and direct bilirubin, alkaline phosphatase, $\alpha$-feto protein, HBsAg and anti-HBs), anti-HCV antibody test and liver ultrasonography were done. Results are as follows; 1. Result of evaluative examination utilizing only the items defined in Regulation was; There were 75 workers with suspected live. disorder(40.3%), 63 with no liver dysfunction (33.9%), 13 with suspected hepatitis B(7.0%), 10 workers with hepatitis B(5.4%), 10 workers with hepatitis B carrier state(5.4%), 10 with alcoholic liver disorders(5.4%), 5 with fatty liver(2.7%). When alternative diagnostic criteria applying additional examination items (drinking history, body mass index, anti-HCV antibody and ultrasonography) diagnosability of liver disorder was increased. When all four items were included, final results were; 23 workers (17.8%) with hepatitis B (10 carriers, 13 suspects and 10 hepatitis B), 10 (5.4%) with hepatitis C(4 carriers, 5 suspects and 1 hepatitis C), 13(7.0%) with alcoholic liver disorder, 45(24.2%) with fatty liver (40 suspects, 5 fatty liver), 410%) with suspected liver disorders and 44 (23.7%) with normal liver. 2. Of examination items defined by Regulation, only SGOT, SGPT, $\gamma$-GTP and HBsAg were significantly different in abnormal rate and mean value, and all other laboratory findings did not showed significant difference between two groups. Drinking history, body mass index and anti-HCV antibody test which are the items that authors included in this study, also showed significant difference between two groups. Utilization of body mass index (BMI) for abnormal liver function group in diagnosis of fatty liver had high specificity (97.6%) but sensitivity (22.3%) was low. Therefore we suggest that SGOT, SGPT, $\gamma$-GTP, HBsAg, alcohol drinking history, BMI and anti-HCV Ab were useful for diagnosis of liver disorders among worker's periodic health examination.

Occupational Dentistry was introduced in Korea about 70 years ago. During the colonial period occupied by Japan till 1945, there were few documents about industrial dentistry, furthermore most cases of occupational diseases and accidents might have been concealed intentionally by the colonial government. After being an independent country, several dentists made efforts to set up 'Preventive Dentistry for Workers' performing specific oral health surveys, even though which were stopped by Korean War. In 1960s' and 1970s', some investigations of oral status were carried out intermittently for specific small groups;white-collar workers, mentally retarded person, buddhist monks and crews of ocean liners. At the same time there was important study in Korean history of occupational dentistry, which was 'a comparison of the oral hygiene conditions in the female workers of a spinning factory at intervals of 30 years.' In 1980s', young researchers began to give attention to erosion of the teeth due to sulphuric acid in the acid-related industry and dental caries due to sugar and flour in the sweets industry. After being democratic labor union movement activated in 1987, hidden and suppressed occupational diseases under the military dictatorship were exposed and flushed in the newspapers. It was shocking for all people that 15-year old boy had been dead due to mercury intoxication after 3-month employment in 1988. In 1990s', the activity for studying oral status of workers in their workplaces was launched and 'Occupational Accidents and Diseases in Oral and Maxillofacial Field' was published. And also The Korean Association of Occupationl Dentistry was established. Oral health examination of workers at the time of employment and of workers exposed to 5 special chemicals at the time of routine special health examination was adopted in 1992, and epocally oral health examination was also included in periodic routine examination of workers' health in 1995. So, occupational dentistry in Korea should cope with the changing needs of working environment and the altering scheme of health examination.

The purpose of this study was to determine the status of dental hygienists in Japan. The study explicated the history, core curriculum, National Examination for Dental Hygienists, work roles of dental hygienists, and workplaces of dental hygienists. This study was based on the government policy report on dental hygienists and the information published by each public institution. The latest statistics presented by the institutions were collected through official websites. The employment information of graduates from Hiroshima University was analyzed based on actual field study. The results of the study revealed that social demand for dental hygienists has steadily increased and policies and education have been revised accordingly. The work roles of dental hygienists have expanded to meet the needs of the treatment and those of public health fields. In line with major policy changes, the educational period has been extended from 1 year to 3 or 4 years, while the mandatory credits for graduation have been established. Licensing examinations were being performed by the local governments since 1948 due to the different situations of dental hygienists in different areas. In 1992, they were converted into a single national examination. The work roles have expanded from assisting dental treatments to health guidance, home care, and perioperative care. Consequently, the number of dental hygienists has increased, especially in healthcare facilities for the elderly. Dental hygienists perform various roles. However, the most essential role is to provide the best oral care services to the patient. The expected role of dental hygienists has expanded in alignment with public healthcare needs and support for the elderly. The government and universities are expected to bring about improvements such as diversifying the channels of education and establishing policies to respond to growing patient needs by cultivating excellent dental hygiene professionals.
