From 1998, Oriental Medical Physicians(OMP) is distributed in Public Health Sector. but long term plan for Oriental Medicine in Public Health is not existed. So, this study is designed for the activation of OMP Subjects in this study were comprised 3 groups of oriental medicine related persons, the group of which are Students of 11 Oriental Medical Schools, Oriental Medical Physicians in Public Health Sector, Specialist Croup of Oriental medicine Policy(total 1,458 persons). Data were collected from July 1st to November 30, 1999. Direct interview with key persons, systematic interview by using of interview protocol, e-mail and facsimile have been conducted. The results of survey were coded by Excel 5.0, and analysed with SAS 6.12 statistical package. Inter-group difference determined by T-test, and descriptive statistics have been examined. Major findings can be epitomized as follows. 1) OMP disposition to multifarious organizations and institutes such as Public Health Centers, Public Health Sub-centers, Public Hospitals, Private Hospitals in Remote-Vulnerable Area, Community Social Welfare Centers, Institutes for Heath Policy Research, etc, will promise an effective use of Oriental Medical Physician. 2) Average number of patients treated by OMP was 22.8, average budget for oriental medical department, in which OMP were affiliated, was 39.6 million Won per year. Direct cost per every patient visit was 7,210.9 Won, which is considered expensive for public health service. Therefore, development and transformation for Oriental Medical Service in Public Health Sector is desirable in economic and political aspects. 3) It is recommended that ${\ulcorner}Advisory\;Committee{\lrcorner},{\ulcorner}Planning\;Commission\;for\; Public\;Health\;in\;Oriental\;Medicine{\lrcorner}$ should be established for the activation and for the support of Oriental Medical Physician in Public Health Sector, 4) Most effective programmes for oriental public health doctor are health service programmes for the elderly, Home health visit, chronic degenerative disease control services(p<0.001). 5) Standard guideline for facilities and equipments of Oriental Medicine Department in Public Health Center is needed for optimal supply of resources and activation of public health activity.

Objectives: This study was carried out to provide safe seafood to the public through simultaneous analysis rapid inspections for residual veterinary drugs in 150 fishery products in 2016. Methods: Quinolones (9), Sulfonamides (14), Penicillins (2), Cephalosporins (3), Tetracyclines (4), Macrolides (4), Lincosamides (2), Pleuromutilin (1), Phenicols (4), benzylpyrimidines (2), Others (1) Malachite green (2), and Melamine (1) were analyzed for 49 species using by HPLC and HPLC-MSMS. Results: There were six unsuitable samples, five among fish and one for crustaceans. Within the standard detection were five fish. The antibiotics found were Quinolones (50%), Tetracyclines (33%) and Penicillins (17%). Conclusions: As a result of the experiment, there were six unsuitable samples, five for fish and one for crustaceans. The most prevalent antibiotics were Quinolones. The quinolone antibiotics are highly persistent in fish tissues, so they require more time than the withdrawal period for other common veterinary drugs. Careful attention is required when they are used in fish farms.

The study on school indoor air quality was carried out at classrooms, computer-rooms, laboratories and play- grounds for carbonyl compounds including formaldehyde during the winter time from November to December 2004 and during the summer time from June to July 2005. The sampling was conducted under the general school condition without any artificial intervention such as the sealing, ventilating or heating at indoor environments. The concentrations of formaldehyde at all types of indoor environments were lower than air quality standard of $120{\mu}g/m^3$ for public facilities. The mean concentrations of formaldehyde at indoors were $4.5{\sim}6.1$ times higher than those at outdoors. From the comparison between two year and one year old schools after construction, the concentrations of formaldehyde in two year old school were $30{\sim}38%$ lower than those in one year old school measured at classrooms and laboratories.

The aim of this study was to screen the contamination by ochratoxin A of mycotoxins in various medicinal herbs. We conducted a survey of ochratoxin A in medicinal herb on the retail market in Incheon in 2016. 116 medicinal herb samples were evaluated for the ochratoxin A contamination. They were analyzed for ochratoxin A using immunoaffinity column and high-performance liquid chromatography(HPLC)-fluorescence detection and the positive samples were confirmed using HPLC-tandem mass spectrometry. Ochratoxin A was detected in 4 medicinal herb samples; the concentrations of ochratoxin A were containing between 20.11 and $372.90{\mu}g/kg$. This study shows that in general, this kind of commodity may be contaminated by mycotoxins. Also this contamination is not limited to only aflatoxin of mycotoxins.

Objectives: The aim of this study was to evaluate the effect of body weight status and sleep duration on the discrete-time hazard of menarche in Korean schoolgirls using multiple-point prospective panel data. Methods: The study included 914 girls in the 2010 Korean Children and Youth Panel Study who were in the elementary first-grader panel from 2010 until 2016. We used a Gompertz regression model to estimate the effects of weight status based on age-specific and sex-specific body mass index (BMI) percentile and sleep duration on an early schoolchild's conditional probability of menarche during a given time interval using general health condition and annual household income as covariates. Results: Gompertz regression of time to menarche data collected from the Korean Children and Youth Panel Study 2010 suggested that being overweight or sleeping less than the recommended duration was related to an increased hazard of menarche compared to being average weight and sleeping 9 hours to 11 hours, by 1.63 times and 1.38 times, respectively, while other covariates were fixed. In contrast, being underweight was associated with a 66% lower discrete-time hazard of menarche. Conclusions: Weight status based on BMI percentiles and sleep duration in the early school years affect the hazard of menarche.

본 연구에서는 치과 CAD/CAM 시스템을 이용하여 SM 가공 방식으로 코핑을 제작 후 주조한 금속 코핑과, AM 가공 방식으로 코핑을 제작 후 주조한 금속 코핑과의 변연 및 내면 적합도를 비교 평가하여 다음과 같은 결과를 얻었다. SM 가공 방식과 AM 가공 방식의 변연 적합도 부분에서는 $120{\mu}m$ 임상적 허용 범위에 존재하였다. SM 가공 방식과 AM 가공 방식의 변연 적합도 및 내면 적합도는 통계적으로 유의한 차이가 있는 것으로 나타났다(p<0.05). SM 가공 방식과 AM 가공 방식으로 제작된 두 그룹의 전체 적합도와 4부분 부위별 적합도 측정은 SM 가공 방식보다 AM 가공 방식이 우수하였다. 결론적으로 금속 코핑의 변연 및 내면 적합도는 SM 가공 방식보다 AM 가공 방식이 우수하였고, 그 결과 값들은 임상적 허용범위 안에 존재하였다. 앞으로 치과분야에서 AM 가공 방식에 관한 연구는 계속되어야 하며, 보다 완성도 높은 금속 코핑 제작이 가능하다고 생각된다.

Objectives: The genus Legionella is common in aquatic environments. Some species of Legionella are recognized as potential opportunistic pathogens for human, notably Legionella pneumophila that causes, Legionellosis. Thus, we investigated the contamination of Legionella pneumophila on water supply systems in Seoul, including cooling towers, public baths, hospitals and fountains. Methods: The existence of 16S rRNA and mip gene of L. pneumophila was confirmed in the genome of the isolated strains by PCR. Results: During the summer season of 2010 and 2011, Legionella pneumophila were detected from 163 samples (21.1%) out of 772 samples collected. Among the 163 strains of L. pneumophila, eighty one isolates belonged to serogroup 1 (57.4%), 23 isolates were serogroup 5 (16.3%), 21 isolates were serogroup 6 (14.9%), 8 isolates were serogroup 2 (5.79%), and 8 isolates were identified in serogroup 3 (5.7%). Through PFGE (pulsed-field gel electrophoresis) analysis using Sfi I, genetic types of L. pneumophila were classified into five (A to E) patterns by the band similarity with excess of 70% from public baths. Conclusions: The PFGE patterns of the serotypes showed a tendency for diversity of L. pneumophila. Our results suggest the existence of serological and genetic diversity among the L. pneumophila isolates.

Field epidemiology involves the implementation of quick and targeted public health interventions with the aid of epidemiological methods. In this article, we share our practical experiences in outbreak management and in safeguarding the population against novel diseases. Given that cities represent the financial nexuses of the global economy, global health security necessitates the safeguard of cities against epidemic diseases. Singapore's public health landscape has undergone a systemic and irreversible shift with global connectivity, rapid urbanization, ecological change, increased affluence, as well as shifting demographic patterns over the past two decades. Concomitantly, the threat of epidemics, ranging from severe acute respiratory syndrome and influenza A (H1N1) to the resurgence of vector-borne diseases as well as the rise of modern lifestyle-related outbreaks, have worsened difficulties in safeguarding public health amidst much elusiveness and unpredictability. One critical factor that has helped the country overcome these innate and man-made public health vulnerabilities is the development of a resilient field epidemiology service, which includes our enhancement of surveillance and response capacities for outbreak management, and investment in public health leadership. We offer herein the Singapore story as a case study in meeting the challenges of disease control in our modern built environment.
