화학사고 현장에서 운용하도록 개발된 휴대용 GC/MS의 적정 시료 주입방식 연구 및 장비의 분석방식별 성능평가를 실시하였다. 사고대비물질 69종 중 4종(methyl chloride, vinyl chloride, benzene, toluene)의 대상물질을 선정하였고, 성능평가용 표준시료는 한국표준과학원에서 제조한 인증표준물질(CRM)을 사용하였다. 연구 결과, 1) 3가지(실린더, 백, 캐니스터)의 시료주입방식 중 백(bag) 주입방법이 가장 적합한 주입방법으로 판단되었다. 백(bag)의 재질이나 용량은 결과에 큰 영향을 미치지는 않았다. 도입 시료의 적절한 purge time은 Loop method와 Tenax method 모두 2분에서 가장 좋은 재현성을 보였다. 2) 휴대용 GC/MS에서 채택하고 있는 3가지 분석방식(sample loop, tenax concentration, carbopack concentration method)에 대한 대상물질의 재현성, 검출한계, 직선성 등의 성능평가 실시 결과 benzene, toluene과 같이 비교적 분자량이 큰 화합물은 Tenax 흡착관에, methyl chloride, vinyl chloride와 같이 분자량이 작고 휘발성이 큰 화합물은 carbopack 흡착관에 농축 분석하는 것이 더욱 재현성 있는 결과를 얻을 수 있었다.

아동의 사회적 성공과 실패에 따른 귀인성향과 사회적 능력과의 관계
박연신 한국아동교육학회 1998 아동교육 Vol.7 No.1
The purpose of this study was to examine the relationship between social attribution variables and social competence variables of children. Subject of the study were 239 children belonging to public elementary school in Dageu city, The tool of the study used was student Social Attribution Scale(SSAS) Bell & McCallum(1995). The data was processed according to the Pearson correlation analysis performed with the ability, effort, luck and task difficulty as social attribution variables and responsiblity, sociality, openness and leadership as social competence variables. The following results were obtained from this study: First, children attributing the causes of their social success to the internal forces{effort and ability) were high positivity correlated with social compentince(leadership). Boy students attributing their social success to internal forces were high positivity correlated with social competence(responsiblity, sociality and leadership), but girl student's attributions were high positivity colrrelated with social competence(openness), Children attributing their social success to the internal forces were low negatively correlated with social competence(sociality and~leadership) Second, children attributing their social failure to the internal forces(ability) were low negativity correlated with social competence(responsiblity, sociality and openness), but children attributing social failure to the internal forces(effort) were low negativity correlated with social competence(sociality). Boy students attributing their social failure to internal forces(luck) were high correlated with social competence(leadship), but girl students's attributions were high positivity correlated with social competence (responsiblity), Third, in case of including social success and failure, chidren attributing the cause of their attribution to luck were high positivity correlated with social competence (responsiblity and openness).

박연신(Yuon Shin Park),황만식(Man Sik Hwang),노혜란(Hye Ran Noh),천광수(Kwang Soo Chun),김성범(Sung Bum Kim) 한국위험물학회 2013 한국위험물학회지 Vol.1 No.1
As the continuous growth of chemical use and chemical industry, the probability of chemical-accident and human exposure also increases. Owing to recent successive chemical accidents, public anxiety and concern about chemicals is increasing. If a chemical accident occurs, it is important to rapid and appropriate first respond based on accurate substances information. The Ministry of Environment as the lead agency managing chemicals need to set systematic management strategies to prevent chemical accidents and to minimize injuries caused by accidents. Thus, 6,770 substances in the domestic legal system of chemical safety management DB has built. Web-based information system was developed to enhance the accessibility and usability of DB. In this article, we discussed and introduced development of chemical database and information system for safety management(KISChem; Korea Information System for Chemical safety management). This product may be useful for enhancing our capability of preparedness and prevention for chemical accidents.

We analyzed the demand of competent authorities requiring adequate technical information for initial investigation of chemical accidents. Reflecting technical reports on chemical accident response by environmental agencies in the U.S. and Canada, we presented information on environmental diffusion and toxic effects available for the first chemical accident response. Hydrogen fluoride may have the risk potential to corrode metals and cause serious burns and eye damages. In case of inhalation or intake, it could have severe health effects. The substance itself is inflammable, but once heated, it decomposes producing corrosive and toxic fume. In case of contact with water, it can produce toxic, corrosive, flammable or explosive gases and its solution, a strong acid, may react fiercely with a base. In case of hydrogen fluoride leak, the preventive measures are to decrease steam generation in exposed sites, prevent the transfer of vapor cloud and promptly respond using inflammable substances including calcium carbonate, sodium bicarbonate, ground limestone, dried soil, dry sand, vermiculite, fly ash and powder cement. The method for fire fighting is to suppress fire with manless hose stanchions or monitor nozzles by wearing the whole body protective clothing equipped with over-pressure self-contained breathing apparatus from distance. In case of transport accident accompanied with fire, evacuation distance is 1,600m radius. In cae of fire, fire suppression needs to be performed using dry chemicals, CO2, water spray, water fog, and alcohol-resistance foam, etc. The major symptoms by exposure route are dyspnoea, bronchitis, chemical pneumonia and pulmonary edema for respiration, skin laceration, dermatitis, burn, frostbite and erythema for eyes, and nausea, diarrhea, stomachache, and tissue destruction for digestive organs. In atmosphere, its persistency is low, and its bioaccumulation in aquatic organism is also low.
