Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

Objectives: The purpose of this study is to standardize the process code of the work environment measurement database (WEMD) for the construction of a job-exposure matrix (JEM). Methods: The standard process code (SPC) was reclassified based on process similarity and drawing upon the code used in the existing K2B. It was supplemented through review by industrial hygiene experts. In addition, an index word database related to SPC was created and used for SPC search. A pilot evaluation project was conducted by experts to evaluate the validity of the newly reclassified standard process code. Results: A total of 70 final SPCs were developed, including 31 processes related to the construction industry. Using the Shiny program, we developed a standard code finder that can be used on the web (https://kscf.shinyapps.io/scf_app/). As a result of the pilot evaluation, it was determined that it was easier to search for standard codes than previous codes, so it was highly utilized. Conclusions: It is expected that JEM construction using industry-process information drawing on WEMD data will be possible using the 70 newly standardized process codes.

Objectives : This study is retrospective chart review research on the combined-prescription of Western and Korean medicine in Public Health Center in rural area. Methods : Researchers reviewed medical records of patients who was prescribed Korean medicine and Western medicine from 1st, Jan, 2019 to 31st, Dec, 2019 in Public Health Center. 50 patients' medical records were included. Results : Total number of treatment is 3,808 cases and 1.3% of them is prescribed Korean medicine and Western medicine simultaneously. Prescription of Korean medicine is 153 cases and Western medicine is 160. Jowiseunggi-tang and Diroba tablet were the most frequently prescribed Korean medicine and Western medicine. Furthermore, Korean Medicine Doctors of Public Health Center use muscular skeletal disease system code(M code among KCD code) for prescription and Western Medicine Doctors use diseases of the circulatory system(I code among KCD code) frequently. Conclusions : We analyze 50 patients who were prescribed both Korean medicine and Western medicine. Mostly, patients were prescribed medicine for different diseases in each clinic. In western medicine clinic, drugs about circulatory or endocrine disease were prescribed frequently and in Korean Medicine clinic, drugs about muscular skeletal disease were most frequently prescribed. This result imply the real world's combination of prescription status that was different from result of National health insurance corporation database. Senior patients in rural area take medicine long period and have various underlying disease. We call for some attention about senior and rural area patients' prescription status in interaction studies of Korean medicine and Western medicine.

Wire codes, introduced by Wertheimer and Leeper, are interesting largely because several case-control studies have reported associations between them and certain types of cancers, including childhood leukemia. This paper is concerned with the reliability of wire codes as a surrogate for residential electric and magnetic field, divided into four categories based on the electrical wiring within 40m of homes. To examine the correlation between spot measurements and wire codes, EMF was measured by using HI-3604 and classified by wire codes. The correlation between long-transformed RMS of magnetic field and wire codes was 0.81. But the correlation between log-transformed RMS of electric field and wire codes was 0.27. The results led us to determine a four category from of the Wertheimer and Leeper code that 1) may be useful in domestic epidemiological studies and 2) is not suitable for electric field exposure. Thus, the critical point of exposure assessment in residential magnetic field is to classify a wire code precisely.

Objectives: The purpose of this study is to evaluate the input status of exposure-related information in the working environment monitoring database (WEMD) and special health examination database (SHED) for the construction of a national exposure surveillance system. Methods: The industrial and process code input status of WEMD and SHED for 21 carcinogens from 2014 to 2016 was compared. Data from workers who performed both work environment monitoring and special health examinations in 2019 and 2020 were extracted and the actual status of input of industrial and process codes was analyzed. We also investigated the cause of input errors through a focus group interview with 12 data input specialists. Results: As a result of analyzing WMED and SHED for 21 carcinogens, the five-digit industrial code matching rate was low at 53.5% and the process code matching rate was 19% or less. Among the data that simultaneously conducted work environment monitoring and special health examination in 2019 and 2020, the process code matching rate was very low at 18.1% and 5.2%, respectively. The main causes of exposure-related data input errors were the difference between the WEMD and SHED process code input systems from 2020, the number of standard process and job codes being too large, and the inefficiency of the standard code search system. Conclusions: In order to use WEMD and SHED as a national surveillance system, it is necessary to simplify the number of standard code input codes and improve the search system efficiency.

본 연구에서는 경기도내 유통되는 수산물 42품목 670건에 대한 총수은 노출량평가를 수행하고, 총수은이 0.1 mg/kg 이상 검출된 시료를 대상으로 기존의 식품공전법과 개발시험방법을 적용하여 비교하였다. 유통 수산물에 대한 총수은 모니터링 결과 총수은에 대한 주간추정섭취량(Estimated weekly intake)은 $0.0742{\mu}g/kg$ bw/week인 것으로 조사되었으며, 이는 JECFA에서 제시한 PTWI $4{\mu}g/kg$ bw/week 대비 1.9% 미만으로 수산물 섭취로 인한 수은 위해성은 안전한 수준으로 평가되었다. 전처리 방법 개선에 따른 메틸수은 분석법 개발을 위해 추출, 정제 부분을 기존 식품공전방법과 다르게 진행하였다. Microwave 추출조건은 용액, 시간, 온도 3가지 조건을 고려하였다. Microwave 추출용액은 10% NaCl, 5 N HCl 용액, 11 N HCl 및 0.1 N NaOH를 선정하여 비교한 결과 회수율이 89.8%로 가장 높고 유화현상도 발생하지 않은 10% NaCl 용액으로 선정하였다. Microwave 추출시간은 10~20분 동안 추출시간을 달리하여 회수율을 비교하였으며, 10분 이상 추출 시 회수율은 100% 이상을 나타냈으나 15분 이상 추출 시에는 유기용매와의 층분리가 어려워 추출시간을 15분으로 선정하였다. Microwave 추출온도에 따른 회수율을 알아보기 위해 $40{\sim}60^{\circ}C$에서 추출 후 회수율을 비교하였다. 추출온도가 증가함에 따라 회수율이 증가하였으나 $50^{\circ}C$ 이상의 온도에서는 회수율이 감소하여 $50^{\circ}C$로 최적화 하였다. 식품공전에서 정제과정에 사용되는 L-cystein은 매 실험마다 제조해야하는 번거로움이 있어 이를 대체하기 위해 0.05~5 N NaOH를 이용하였다. NaOH용액의 농도가 높아질수록 회수율이 증가하는 경향을 보였지만 2 N NaOH 이상의 농도에서는 재현성이 떨어지고 거품발생량이 증가하여 2 N NaOH용액을 정제용액으로 선정하였다. 이 실험들을 바탕으로 수산물 중 메틸수은 시료 전처리 방법을 제안하였다. 제안된 시료전처리 방법은 기존 시험방법에 비해 검출효율이 높고 전처리 시간을 절약할 수 있는 것으로 나타났다. 따라서 수산물 전반에 대한 모니터링 수행 시 스크리닝 분석법으로 유용하게 활용할 수 있을 것으로 생각된다. 우리나라의 수산물 섭취량이 세계에서 가장 많은 것으로 알려진 만큼 비의도적 유해물질인 메틸수은에 대한 종합적이고 체계적인 관리가 이루어져야 될 것으로 판단된다.

Objectives : The objective of this paper is to discuss the importance of obtaining informed consent for conducting epidemiological studies and public health activities, based on the Report of the UNESCO's Working Group on Informed Consent. Methods : The Report of the UNESCO's Working Group on Informed Consent was reviewed and discussed in connection with the ethical considerations of public health activities and epidemiological research. Results : It was at the Nuremberg Trial for the German war criminals of the Second World War that the principle of 'consent' was first stated as a consequence of the medical abuses carried out during the War. As a result of the Trial, the Nuremberg Code came out in 1947. Since then, various international declarations or ethical principles on 'informed consent' have been developed and published. These ethical principles on 'informed consent' have mostly to do with the clinical research that involves human subjects, and not with epidemiological studies and public health activities. However, UNESCO recently issued a comprehensive Report on Informed Consent based on the Universal Declaration on Bioethics and Human Rights adopted in 2005, and this included detailed guidelines on informed consent in epidemiological studies and public health activities. Conclusions : Universal Declaration on Bioethics and Human Rights emphasizes the principle of autonomy to protect the human rights of the human subjects involved in any public health activities and epidemiological research. As a practical guideline, obtaining informed consent is strongly recommended.

토착 미생물은 친환경적 정화에 중요한 역할을 한다. 원유(crude oil)를 분해하는 80균주를 인천 연안에서 분리하고 oil film collapsing방법을 이용하여 유화능이 있는 12균주를 선별하였다. 이들 균주에 대해 ${\rho}$-nitrophenyl butylrate를 기질로 이용하여 리파아제(lipase)활성과 n-hexanedecane을 기질로 이용하여 유화(emulsification)활성을 측정하여 원유 분해 활성이 좋은 Incheon9를 선별하고 gas chromatography (FID)로 paraffine계 탄화수소를 감소시키는 것을 확인하였다. 이 균주의 16s rRNA유전자 분석을 통해 Acinetobacter sp.로 동정하고 NCBI에 등록하여 accession code (KF548540)를 부여 받았다. Acinetobacter sp. Incheon9의 성장과 유화능이 최적 배양 조건은 $20^{\circ}C$, pH 7, 1% NaCl였으며 대수증식기 기간에 가장 높은 유화능을 보였으며 탄화수소가 짧은 trybutyrin에서 분해능력이 좋았다. 이번 연구결과는 환경오염에 활용 가능한 미생물자원군의 확보를 위한 연구였으며 추후 활용을 위해서는 실제 환경에서 동일한 활성을 가지는지 여부에 대한 연구가 추가로 진행되어야 할 것이다.
