고해상도 전자기후도 기반의 농가맞춤 조기경보서비스를 구현하기 위해서는 실측기상자료가 없는 곳의 평년기후를 복원해야 한다. 일별 기상자료 복원에 드는 시간과 노력을 절약하기 위해 간이산출방식이 널리 사용되어 왔는데, 본 연구에서는 이렇게 간소화된 방식을 통해 제작된 평년 기후값이 어느 정도의 오차를 수반하는지를 분석하기 위하여, 평년기간(1981-2010)에 대한 일별 기상 값을 모두 복원하고, 이를 '시간적', '공간적' 간소화를 진행한 평년기후값과의 비교를 통해 기상위험의 예측 결과의 차이에 대해 분석하였다. 이를 위해 여러 재해관련 지수 중에서 많은 종류의 기상자료를 필요로 하는 농업가뭄지수를 이용하였으며, 섬진강 유역 일대의 10개 시군을 선정하였다. '시간'규모를 간소화한 평년 값은 30개년(1981-2010)에 대해 일별로 평균한 값을 이용하여 고해상도 분포를 제작하였으며, '공간'규모를 간소화 평년 값은 실험지역에 대하여 집수역 단위로 제작한 평년 값을 이용하였다. 먼저 '잔여수분지수'의 경우 '시간'규모 간소화 평년 값의 경우 과대 추정되었으며, '공간'규모 간소화 평년 값의 경우 과소 추정되는 경향을 나타냈다. 또한 2017년 1월부터 7월까지의 가뭄지수를 제작한 결과, 평년 자료 별로 가뭄의 정도를 모의한 결과에 차이가 있었으며, 지역적인 편차 또한 확인 되었다. 본 연구를 통하여 '간소화'된 제작방식을 통한 평년 기후 값이, 이를 이용해 재해위험을 산출한 결과에 영향을 미칠 수 있음을 확인하였다.

Objectives: Firefighters and police officers are exposed to various occupational hazards. No studies in Korea have investigated the occurrence of cancer by type of cancer for the two occupations. This study aims to investigate the risk of occurrences associated with types of cancers in firefighters and police officers. Methods: Utilizing National Health Insurance(NHI) Claims data from 2006-2015, the study included 8,871,468 general workers, 25,001 firefighters, and 102,274 police officers. Using general workers as a control group, we calculated the standardized incidence ratios(SIR) by types of cancer for firefighters and police officers. After calculating the SIR for all subjects, the SIR was calculated by stratifying according to gender. Results: SIR of colon cancer 1.38(95% CI, 1.11-1.69), cancer of the liver and intrahepatic bile ducts 1.27(95% CI, 1.04-1.54), and 1.88(95% CI, 1.28-2.65) bladder cancer were higher firefighters than general workers. SIR of Lip, oral cavity, and pharynx 1.26(95% CI, 1.07-1.47), Stomach 1.14(95% CI, 1.06-1.23), colon 1.33(95% CI, 1.21-1.46), liver and intrahepatic bile ducts 1.21(95% CI, 1.10-1.32), pancreas 1.24(95% CI, 1.02-1.49), other skin 1.60(95% CI, 1.26-2.00), bladder 1.27(95% CI, 1.04-1.54), other urinary tract 1.46(95% CI, 1.27-1.68), other parts of central nervous system 1.68(95% CI, 1.10-2.46) were higher police officers than general workers. Conclusions: Both firefighters and police officers are exposed to various cancer occurrence risks, necessitating the development of occupational medical protection measures to reduce risk exposure factors.

기후변화는 농업에 막대한 영향을 미치며, 특히 지구 온난화로 인해 미래로 갈수록 기온과 습도가 현재와는 다른 양상으로 변화될 것으로 예측된다. 현재와 다른 기후 환경하에서는 농작물과 더불어 가축들은 환경변화에 따른 스트레스에 노출될 위험성이 높아질 수 있다. 특히 미래 기후는 평균기온 상승으로 설명할 수 있는데, 고온 스트레스에 대한 위험도는 기온과 상대습도를 통해 계산되는 온습도지수를 통해 평가할 수 있다. 본 연구에서는 기상청 종관 관측 10개 지점에서 1961년부터 2020년까지 60년간 수집된 기온과 상대습도 자료를 활용하여 지점별 온습도지수를 기간에 따라 비교하고, 1981년부터 2020년까지 고해상도 분포도로 제작된 기온과 상대습도 분포도 자료를 통해 온습도지수를 분포도 형태로 제작하여 시간의 흐름에 따른 공간적인 변화량을 분석하였다. 또한, 온습도지수를 활용해 산출할 수 있는 고온 스트레스 발생 일수를 기간에 따라 비교하였다. 온습도지수는 과거에서 현재로 이어지는 동안 평균적으로 상승하는 양상을 나타냈으나 지점별로 상승 패턴은 차이가 있었다. 또한 온습도지수가 상승함에 따라 고온 스트레스 일수 또한 증가하는 양상을 나타냈으며, 이는 향후 열로 인한 축산업 분야의 비용증가를 예상할 수 있다. 본 연구의 결과는 온습도지수를 통해 가축의 고온 스트레스 위험성을 평가할 수 있음을 시사하며 향후 기후 변화 시나리오 자료를 통한 미래 기간에 대한 온습도지수 분석에 대한 연구가 필요할 것이다.

Along with the development of digital technologies, the information obtained during the medical procedures was working as a source of valuable assets. Especially, the secondary use of personal health information gives the ordeal to privacy protection problems. In korea, the usage of personal medical information is basically regulated by the several laws in view of general and administrative Act like Medicine Act, Public institutions' personal information protection Act, Information-Network Act etc. There is no specific health information protection Act. Health information exchange program for the blood donor referral related with teratogenic drugs and contagious disease and medical treatment reporting system for income tax convenience are the two examples of recently occurred secondary use of health information in Korea. Basically the secondary use of protected health information is depend on the risk-benefit analysis. But to accomplish the minimal invasion to privacy, we need to consider collection limitation principle first. If the expected results were attained with alternative method which is less privacy invasive, we could consider the present method is unconstitutional due to the violation of proportionality rule.

In the past, when the credit card was delivered to the customer, the postal agreement and receipt were signed by customer. The repossessed documents were sent back to the card company through the reorganization process. The card company checks the error by scanning and keeps it in the document storage room. This process is inefficient in cost and personnel due to delivery time, document print out, document sorting, image scanning, inspection work, and storage. Also, the risk of personal data spill is very high in the process of providing personal information. The proposed system is a service that receives a postal agreement and a receipt to a recipient when signing a credit card, signing the mobile image instead of paper, and automatically sending it to the card company server. We have designed a system that can protect the cost of paper documents, complicated work procedures, delivery times and personal information. In this study, we developed 'u-paperless' and secure credit card delivery system applying electronic document and security system.

A decision support system, Watershed Analysis Risk Management Framework(WARMF), was applied to the Kyungan Stream watershed, a tributary of Lake Paldang, for calculation of total maximum daily loads(TMDL). The WARMF system was developed by Systech Engineering, USA, and has been successfully used in several watersheds, for TMDL studies. The study area was divided into 14 sub-basins, based on digital elevation model(DEM). The integrated watershed and stream model of WARMF was validated by flow and BOD data measured during the year of 1999. There were reasonable agreements between model results and field data, both in water flow and BOD. The validated Kyungan WARMF was extensively utilized to study the quantitative relationship between waste loads and receiving water quality. Based on TMDL guideline at Paldang Lake and Kyungan Stream, the water quality criterion were set to be 3.0mg/L, 3.5mg/L, and 4.0mg/L at the watershed outlet. The allowable waste loads of BOD, both from point and non-point sources, were determined at each water quality criterion. From this study, it was concluded that the WARMF provided several advantages over the conventional application of watershed and stream models for TMDL study, such as time variable simulations, multiple possible soutions, and reduction loads for goal water quality, etc.
