  • Cutaneous injuries stung by jellyfish are not uncommon in human exposed to marine environments. Most of the cases occur to scuba divers, fishermen, and travelers swimming at the beach. The symptoms vary from mild dermatosis to fatal systemic reaction. Some group of jellyfish like Atlantic Portuguese man-of-war (Physalia physalis) provokes acute severe skin injuries with systemic symptoms of nausea, bradycardia, and rarely anaphylaxis. But it is unusual case that allergic dermatitis caused by Scyphistoma which is polyp stage of jellyfish (Aurelia aurita) happened to zoo keepers working at indoor dolphin pool. This case report is about dermatosis with symptoms such as painful, irritant, itching, and erupted skin lesions on the neck and face of zoo keepers working at dolphinarium in Seoul zoo, Korea.

  • Seat belt is an important means to protect drivers and passengers from the damages by car accidents. Many ways to increase the seat belt wearing rate have been proposed through human factors researches. The primary ways to increase seat belt use rate have emphasized the intention-behavior cycle. This study focused on the gap between intention and behavior. The gap may be bridged by the habit for seat belt use behavior. Divers following a desirable car starting sequence, from sitting on the chair, fastening seat belt, starting engine to moving a car, reported that higher belt wearing rate and unconscious behavior (automated response). That is, the habitualized procedure knowledge prevented drivers from forgetting to fasten their seat belt. The reminder systems such as warning light and warning sound could not significantly give an influence in remembering to fasten seat belt. In order to increase the seat belt use rate, the desirable car starting procedure should be included in the driving education program.

  • This study was aimed to identify a study on risk perception and safety knowledge and awareness of scuba diver. In order to achieve this purpose, a total of 310 customers over the age of 20 were selected as study participants form diving pools and dive resort in Seoul, Gyeonggi, Gangwon, Gyeongsang area using the convenience sampling method. However, only data from 295 customers were used after screening the data for reliability. The instrument for data collection was a questionnaire, and descriptive statistics, inter-item consistency reliability, t-test, ANOVA, post hoc test, correlation analysis, pearson chi-square test were conducted on the data using the SPSS 21.0 version statistical package program. The followings are the results: First, risk perception differs significantly according to age, education level, occupation and participation period. Second, participation period and safety knowledge have positive correlation.

  • 최근 군사 분야에서 사용하는 기존 판독시스템을 개선하기 위해 판독보고서를 기반으로 문장을 추천해주는 시스템이 연구되었다. 제안한 시스템에서 문장을 추천하기 위해 Beam Search 알고리즘을 사용하는데, Beam Search 알고리즘은 추천해 주는 문장의 다양성이 떨어진다는 문제가 있었고, 이를 해결하기 위해 Divers Beam Search 알고리즘을 응용하여 적용하였다. 이는 판독관들의 업무효율을 높임으로써 업무 과 부화를 해결할 수 있을 것이다.

  • This is the first Korea study to evaluate the effects od the safety of ambulance driving and the occurrence of ambulance traffic accidents and to provide basic informaion for the description of various factors to reduce the ambulance traffic accidents. The major insturment of this study were Krean Self-Analysis Driver Opinionnaire. Questionnaire contains 8 items which measure driver's opinions or attitudes : driving courtesy, emotion, traffic law, speed, vehicle conditions, the use of drugs, high-risk behaviors, and human factors. To take the analysis of data, the total of 350 divers were investigated ambulance divers and others in Taejon City and others (6 City) from 1996. 1. July to 1996. 31. July. The data were analyzed by the descriptive statistics and the logistic regression - path analysis - with SPSS and SAS package program. The result are as follows : 1. There was desirable attitude group(16.2%) and undesirable attitude group(17.6%) on safety ambulance driving. 2. It have suggested that risk factors of ambulance traffic accidents much affected with emotion and speed control on safety ambulance driving < Y(Accdient) = -2.64 + 0.57 $X_1$ (Emotion Control) + 0.30 $X_2$(Seed control) + E > and motor traffic acident much affected with emotion control and high-risk behavior on safety driving < Y(Accident) = -1.11 + 0.33 $X_1$(Emotion Control) + 0.29 $X_2$(High-risk Behvior) + E > 4. The primary emphassis of ambulance drivers was make us realized that improthatnt factors on safety ambulance driving were 1)making way for emergent ambulance, 2)driver's career, 3)The ability of emergency medical technics, and the knowledge or under standing of ambulance way difficut(or easy) of accdess. 5. Almost 96.6% of respondents have agreed to necessity of emergency medical technics for ambulance drivers. 6. Almost 94.6% of respondents have consented to necessity of emergtency medical technicians for ambulance driving. 7. It have suggested that the proportion of traffic accident proportion by desitable attitude group(16.7%) was much less than that of undesirable attitude group(30.8%) on safety ambulance driving(P < 0.05)/Ps) Accidents are unplanned, unforesen incidents which can lead to harmful or unfortunate outcomes, Collisons are not accidents, since the basic cause of the majority of collisons invovles high-risk human behavior. Although there are many factors which contribute to accident causation, four basic factors seem to predominate in most traffic related situations. These four factors include: the human factor, the vehicle factor, the environmental factors and destination factor(Peto G. et al. 1995).

  • 성과 관련된 다양한 물음들에 생물학적으로 접근하여 해명하려고 시도하는 입장에서는 인간의 성적 욕구 및 성향과 본성 그리고 성역할 등에 대한 설명을 사회나 문화와 같은 인간의 인위적 제도들에 의존하여 제시하기보다는 진화론적 입장에 기대어 인간 본성과 성 심리의 생래적 측면을 강조하고자 한다. 이러한 입장은 성과 관련된 인간의 모든 특성이 생물학적으로 결정된다는 입장을 강하게 표명하고 있으므로, 생물학적으로 모든 것을 설명할 수 있는가의 물음에 직면하게 되면 강한 주장을 유보할 수밖에 없으리라 생각된다. 그러나 인간의 본성이 역사적으로 변화를 겪는다는 사실이 인간이 역사적으로 진화하고 있음을 함축하는 것은 아니다. 그러므로 진화론의 입장이나 생물학적 결정론을 무조건 수용하기는 어렵다. 따라서 이러한 입장에 비판을 가하고 새로운 주장을 하는 푸코의 입장을 대치시키는 작업은 기존이론의 난점과 문제점을 명확히 할 수 있을 뿐만 아니라 새로운 관점이 가져올 수 있는 이해의 지평에 쉽게 다가갈 수 있게 해준다. 또한 푸코의 기본적인 철학적 입장이 성 담론과 관련하여 어떻게 응용, 적용될 수 있는지를 고찰하고 분석함으로써 푸코의 해석과 관점의 특색 및 난점을 드러낼 뿐만 아니라 성 담론에 대한 새로운 관점이 가져올 수 있는 다양한 이해의 지평에 접근할 수 있는 기회를 제공할 수 있게 되었다.
