Since 2003, the National Institute of Environmental Research (NIER) of Korea has been conducting "The monitoring study on exposure level and biomarkers of environmental pollutants" in the Ulsan industrial complex with the goals to establish a surveillance system for residents, to evaluate the health effects associated with chronic exposure to environmental pollutants and to develop the environmental health indicators in Ulsan industrial complex. This program consists of three phases an initial or foundation phase in which the program is developed, made operational and extended to the community, followed by an evaluation and accountability assessment of the surveillance system and finally an improvement in the quality of life and the maintenance of good health for Ulsan residents. In the period 2003 to 2008, the study program developed the surveillance system which will be used for the full-length survey. All participants in this study were contacted at a presentation meeting for residents, introduced to the objectives and protocols of the survey, and asked to participate. Informed consent was obtained from each participant. The study is now underway and includes questionnaires, health examinations and the analysis/collection/banking of bio-sample such as blood and urine. To date 828 subjects have participated and already 588 subjects have been followed up. We are committed to complete health examinations and to arrange storage of biosample for all participants. During the current year, we will analyze metals (Pb in blood and Cd, inorganic As and Hg in urine) in 1,972 samples and VOCs (11 species) and PARs (18 species) in 300 samples (blood sample). Moreover, the summary of the first step and the further preparation of the second step are currently underway. In this article, we introduce the study and its protocols and the distribution and size of the study participants. In conclusion, this survey will be continuously conducted on the established cohort and will enable the identification of relationship between environmental pollutant exposures and the health status of residents in Ulsan industrial complex.

This paper focuses on the outcome-based curriculum of Inje University College of Medicine to describe our curriculum development process and results. Starting in 2006, we have revised the curriculum based on the competency-based clinical presentation curriculum. We stated clearly the learning outcomes from the social needs and educational goal of our university. We defined 8 exit outcomes and specified phase outcomes, course outcomes, lesson outcomes, and outcome objectives. By 2012, we identified 128 clinical presentations and 149 basic scientific concepts. Various evaluation and assessment methods and teaching-learning strategies were assigned to each outcome. Problem-based learning, standardized patient practice, and learning portfolios are the main strategies of our curriculum. We have performed a progress test to assess the level of achievement of students' outcomes. We have also collected feedback from students and faculty members about the curriculum, including every lesson, course, and the overall curriculum. To maintain this change of the curriculum, we reorganized the curriculum committee, educational faculty and teams, and administrative support system. To fine tune this curriculum, we have held three 3-day workshops on curriculum development and weekly meetings. We believe this is just the beginning of developing the curriculum of Inje University. Further upgrades will be necessary to continue to improve medical education.

Objectives : I used a case-crossover design to investigate the association between air pollution, and hospital admissions for asthmatic children under the age of 15 years in Seoul, Korea Methods : I estimated the changes in the levels of hospitalization risk from theinterquartile (IQR) increase in each pollutant concentrations, using conditional logistic regression analyses, with controls for weather information. Results : Using bidirectional control sampling, the results from a conditional logistic regression model, with controls for weather conditions, showed the estimated relative risk of hospitalization for asthma among children to be 1.04 (95% confidence interval (CI), 1.01-1.08) for particulate matter with an aerodynamic diameter less than or equal to 10m (IQR=40.4ug/m3); 1.05 (95% CI, 1.00- 1.09) for nitrogen dioxide (IQR=14.6ppb): 1.02 (95% CI,0.97-1.06) for sulfur dioxide (IQR=4.4ppb): 1.03 (95% CI, 0.99-1.08) for ozone (IQR=21.7ppb): and 1.03 (95% CI, 0.99-1.08) for carbon monoxide f10R=1.0ppm). Conclusions : This empirical analysis indicates the bidirectional control sampling methods, by design, would successfully control the confounding factors due to the long-term time trends of air pollution. These findings also support the hypothesis that air pollution at levels below the current ambient air quality standards of Korea is harmful to sensitive subjects, such as asthmatic children.

The types of dam-break have been classified as instantaneous and gradual failure. Equations for estimating the peak outflow have been derived respectively as a metric unit. New dimensionless routing curves have been deveoloped based on the distance parameter which has been used in SMPDBK and hydro-geometric characteristics of dams and reservoirs in Korea. These suggested curves can be used for any case of the flow of supercritical or subcritical. The computed peak flowrate shows the trend of decreasing dependence on the Froude numbers as it increases. These curves are applied to Hyogi dam. and the results have good agreements with the data observed in the peak discharges, peak elevations and flood travel time. The simplified dam-break model in this study would contribute effectively to forecast the dam-break flood in this country with minimum informations in a short time. 댐 붕괴의 유형을 순간적 붕괴와 점진적 붕괴로 구분하였고 각 경우에 대하여 첨두유량의 산정식을 Metric 단위로 환산하여 유도하였다. 기존의 SMPDBK 모형에서 사용된 거리 매개변수의 개념을 도입하고 국내 댐 및 저수지의 자료를 기초로 한 새로운 무차원 홍수추적곡선을 유도하였다. 새로운 추적곡선은 기존의 모형에서 다루지 않은 사류(射流)상태의 경우도 포함하고 있으므로, 산지하천이 많은 국내유역에 적용시킬 수 있도록 하였다. 본 연구에서 유도된 무차원 홍수추적곡선은 Froude 수가 증가됨에 따라 유량감쇠비(流量減衰比)도 증가하고 있는 경향을 보여주었으며, 그 증가율은 Froude 수가 증가함에 따라 감소하고 있었다. 특히, 사류의 경우에서는 Froude 수가 커짐에 따라 그 증가율이 비교적 작게 나타나는 특성을 보이고 있었다. 효기(孝基) 댐 붕괴의 경우에 대하여 본 연구에서 유도한 무차원 홍수추적곡선을 적용한 결과를 실측치 및 동역학적 모형에 의한 계산결과치와 비교할 때, 댐 붕괴 지점에서의 첨두유량, 최고수위 및 홍수파의 도달시간 등에 있어 비교적 잘 일치되었다. 본 연구결과는 국내의 중소 댐에 경제적으로 활용될 수 있을 것으로 기대된다.

To investigate the average meat production ability of meat hogs and the quality of perk produced primarily for export, the carcass data and cutting yield data were obtained from 7,689 heads of meat hogs and were analysed by production areas. The chemical analysis of muscles and the physical properties of fat were made. The results obtained were summarized as follows. 1. The average postnatal days of the meat hogs was 191 days, and the average live weight of hogs that were fasted for 10∼12 hours was 88.48㎏. From these the market weights was estimated to be about 90㎏. 2. The average dressing percentage was 75.40%, and the average backfat thickness was 2.91㎝ that, this is supposed to be No.2 grade according to the carcass grading standard of Japanese. 3. The average four lean cuts yield was 68.75% and the five primal cuts was 82.31% on the carcass weight basis. 4. The total fresh pork including tender loin was 59.66% on the carcass weight basis and this was 49.98% on the live weight basis. 5. The total abnormality was 9.59% and 36.9% of the total abnormalities was found in the gastro-intestinal tract.

장주기파(長週期波)에 의한 항내(港內)의 반응(反應)을 예측(豫測)하기 위하여 비선형(非線型) 편미분방정식(偏微分方程式)으로 표현(表現)되는 2차원(二次元) 부정류(不定流)의 운동방정식(運動方程式)과 연속방정식(連續方程式)을 확정(確定)하고, 이 식(式)들에 Abbott의 Implicit 형(型) 차분형(差分型)을 적용(適用)하여 유한(有限) 차분방정식(差分方程式)의 형태(形態)로 유도(誘導)한 후(後), double sweep 알고리즘에 의하여 해석(解析)하는 수학적(數學的) 모형(模型)을 개발(開發)하였다. 본(本) 모형(模型)은 임의(任意)의 파형(波形), 풍속(風速)과 수심(水深), 위도(緯度) 등(等)을 입력자료(入力資料)로 하여 임의(任意)의 지형(地形)을 가진 항내(港內)에서의 반응(反應)을 해석(解析)할 수 있도록 설계(設計)되었다. 특(特)히 파향(波向), 이송항(移送項), 항입구(港入口)로 되돌아 나오는 에너지의 방사현상(放射現象) 등(等)을 수치해석적(數値解析的)으로 처리(處理)하는 수법(手法)의 개발(開發)에 관(關)하여 연구(硏究)하였다. 본(本) 모형(模型)에 의한 해석결과치(解析結果値)는 1차원(次元) 및 2 차원(次元) 정진동(靜振動)(seiche) 수치실험(數値實驗)을 통(通)하여 검정(檢定)하였으며, Ippen과 Goda의 이론해석치(理論解析値) 및 실험결과치(實驗結果値)와 비교(比較)하였다. A mathematical model for the two-dimensional unsteady flow was developed by introducing Abbott's implicit finite difference operator and double sweep algorithm, which could be applied to simulate the respose of a harbor against the intrusion of long waves through the entrance connected to open sea. In order to improve its accuracy corresponding to the field phenomena, bottom resistance, Coriolis force, wind effect terms were included and wave direction and radiating effect was considered. The result of seiche test was always stable and the amplitude was accurate. Some phase shift was occured, but it could be reduced by using small values of Courant number and many points per a wave length as well. A comparision with the Ippen and Goda's theoritical and hydraulic experimental works was fulfilled.

이종태,Lee, Jong-Tae 한국환경보건학회 2014 한국환경보건학회지 Vol.40 No.2

Objectives: The main purpose of this review is to introduce the current status of environmental health indicators of Korea and to share our experience of the developmental process of Korean version of environmental health indicators. Methods: This paper describes 1) the background of environmental health indicators; 2) the ways how we developed environmental health indicators of Korea; 3) the current status of selected indicators; and 4) suggestions for the further policy development. Results: The 6-year long project for the development of environmental health indicator systems in Korea could provide outputs on three major distinct aspects on the indicator issues. Firstly, we have developed the rational process/manual so that the government can select and advocate the potential indicators with a relatively objective manner. Secondly, we have suggested the potential candidate indicators which can be implemented immediately. We also pooled all indicators in order to evaluate the summary index which we expect to tell the status of environmental health. Third, we provided suggestions on the further utilization of this indicator system. Conclusion: The mission of environmental health policy is to resolve the public health problems occurring because of hazardous environment. In order to identify the environmental determinants of the community health problems and to evaluate the effectiveness of the policy implemented, these environmental indicators can be used. Therefore, the government should implement this ready-prepared system of environmental health indicators.
