허성일,오신범,이채욱 대구대학교 과학기술연구소 2001 科學技術硏究 Vol.8 No.1

This paper identifies aircraft operations of Ulsan airport, analyzes factors for cause through weather elements, and explores the application of weather minima according to the directions of runway. Directions of the runway at Ulsan Airport consist of one, 18-36. The wind distribution is characterized by a northerly (N) wind direction that coincides with the runway direction (head and tail winds) while a southwesterly (SW) wind direction acts as a cross wind with the runway direction as a reference, requiring caution when an aircraft lands and takes off. The least visibility is prominent from May to June. In addition, due to topographical characteristics of the area, visibility obstruction from dense fog is frequent with the occurrence of radiation fog. But the effects of sea fog are almost non-existent. The analysis of weather elements at Ulsan according to aircraft operations is based on a fact that lowest weather minima have been set for run%vay, along with landing and take-off methods.

연구목적 : 우리나라에서 산업 재해로 신체적 손상을 입고 입원해 있는 일부 근로자들을 대상으로 PTSD 발병여부를 조사하고, 산업 재해와 관련된 위험 인자를 파악하여 산업재해 이후 근로자들이 겪게 될 신체적 건강문제 뿐만 아니라 정신적 건장 문제 회복에 도움을 주고자 하였다. 방 법 : 2000년 7월에서 2000년 9월 사이에 산업 재해로 인해 신체적인 부상을 입고 입원 중인 인천 소재 산재병원의 남성 입원환자 47명을 대상으로 PTSD 발병여부와 관련 인자를 연구하기 위하여 구조화된 설문 조사와 CAPS를 이용한 진단적 면담을 시행하였다. 결 과 : CAPS를 이용한 면접조사 결과 최종 연구 대상자 47명중 12명(25.5%)이 PTSD로 나타났으며, 모두 증상의 지속 기간이 3개월 이상인 만성 외상후 스트레스장애로 분류되었다. PTSD군 12명과 non-PTSD군 45명을 비교한 결과 BDI, STAI-I, STAI-II, IES 점수는 PTSD 군에서 유의하게 높게 나타났다. 또한 SCR-90-R의 세부항목 중 편집 사고를 나타내는 PAR 점수가 유일하게 두 군 사이에 유의한 차이를 보이지 않았고 그 외의 항목들은 PTSD 군에서 유의하게 높았다. 산재 관련 위험 인자의 비교에서 환자가 주관적으로 보고한 의식의 상실 경험만이 PTSD군에서 유의하게 높게 나타나 이전의 다른 연구자와 일치된 소견을 보였다. 결 론 : 이상의 결과는 산재 사고 이후에 PTSD가 발생하고, 증상이 장기간 지속되어 만성화를 겪을 가능성이 있다는 것을 보여준다. 위험 인자 중에서 사고 관련 위험 인자로 의식의 상실에 대한 주관적인 보고만이 관련성이 있는 것으로 나타났으나, 그 외의 다른 인자들은 관련서이 없는 것으로 나타났다. 그러나 여러 가지 연구의 제한점이 많으므로 연구 시점을 달리하고 많은 대상자를 포함한 후속 연구를 시행해야 산업재해와 PTSD에 대한 이해를 높일 수 있을 것으로 사료된다. Objectives : This study was conducted to assess the development of posttraumatic stress disorder(PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. Methods : Forty-seven occupational accident patients with physical injuries were administered BDI. STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). Results : 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident related factors(<0.05). Conclusion : The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only significant risk factor for PTSD in occupational accident patients.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

The future society is expected to be rapidly change in all areas, that is, the length of change time is becoming much smaller than that of generation time. It is very important to prepare the citizens who possess scientific literacy which actively cope with the rapid changes and specialization of society. The sources of rapid changes may be due to the developments in science and technology. Therefore, the importance of science education will be increasingly high. Scientific literacy should be improved basically and systematically from the early stages of formal education. Teachers who are responsible to educate children should be able to research in the areas of science education as well as science itself, and to have capacity to transmit them to the classroom. To do this, the graduate course and the science education within the system beyond the level of college education are essential parts of teacher education. In the graduate course, it is important that science itself and pedagogy of science should be balanced.

Exploring the effect of the human brand on consumers' decision quality in online shopping: An eye-tracking approach

Chae, Seong Wook,Lee, Kun Chang Emerald Group Publishing Limited 2013 ONLINE INFORMATION REVIEW Vol.37 No.1

<B>Purpose</B> - The purpose of this paper is to investigate how employing human brands affects consumers' decision quality in an online shopping environment by analysing visual attention using an eye-tracking technique. <B>Design/methodology/approach</B> - The experimental design used to examine the effect of human brands in an online shopping environment was a two-factor repeated measure with two levels for each factor. The first factor of the design was a within-factor measure of the product type, and the second was a between-factor measure of the level of perceived decision quality. For this experiment 38 healthy participants were recruited at a university in South Korea. <B>Findings</B> - First employing human brands in an online shop influences consumers' perceived decision quality. Second the results support a significant difference in perceived product trust between the two perceived decision quality levels. Finally the product type influences consumers' perceived trust towards the product. <B>Research limitations/implications</B> - This research has the limitations of a relatively small sample size and the use of a sample of university students, which may not be representative of the general population. Future researchers could utilise experiments to analyse the message area of the screen for detailed product descriptions and include various samples, which could result in additional insights and generalised experimental results. <B>Practical implications</B> - Employing human brands can improve consumers' decision making processes and enhance the quality of their decisions by reducing cognitive effort and appealing to consumers emotionally through heuristic choices. In addition it can increase trust towards products and, furthermore, lead consumers to think positively about the quality of the decisions they make. The paper suggests that companies apply human brands in online shops to improve consumers' decision quality and obtain competitive advantage. <B>Originality/value</B> - One of this paper's contributions is employing a multi-method approach, a self-reported questionnaire and eye-movement data, to gain a deeper understanding of the data when observing a complex phenomenon, as consumers themselves may not be aware of their reactions in such situations.

소셜네트워크서비스에서 집합적 효능감이 이용자들의 자기노출에 미치는 영향

채성욱 ( Seong Wook Chae ) 한국지식경영학회 2018 지식경영연구 Vol.19 No.1

With the development of information technology, social network services (SNS) such as Facebook and Twitter became popular and many users disclose their personal and sensitive information like private story, photographs and location information through posting and sharing. Despite the privacy concerns in SNSs, individuals continue to disclose their identity online. This phenomenon is called 'privacy paradox'. The purpose of this study is to examine the role of collective efficacy on self-disclosure in SNS context and to explain privacy paradox phenomenon. Drawing upon the communication privacy management theory, research model was developed and empirically tested with cross-sectional data from 306 individuals. Results revealed that collective efficacy has a direct positive effect on self-disclosure while privacy risk is negatively related to self-disclosure. However, privacy concern is not directly related to self-disclosure. The relationship between privacy concern and self-disclosure was moderated by collective efficacy.

모바일 소셜 네트워크 게임 사용자의 이타주의적 행위가 게임 지속성에 미치는 영향: 사회 관계적 자본의 매개효과를 중심으로

채성욱 ( Seong Wook Chae ),강윤정 ( Youn Jung Kang ) 한국정보시스템학회 2016 情報시스템硏究 Vol.25 No.1

Purpose As social network games (SNG) enjoy rapid growth in the market and become a major sector of the gaming industry, it is of great interest to examine the how users continuously use SNG. In SNG, the users’ social interaction is the most prominent advantage of the social network, as well as the entertainment afforded by the game. This study explores the relationship between altruism, which is considered the most prominent characteristic of SNS, and the continuance usage intention, as well as the moderating role of social capital. Based on social capital theory and organizational citizenship behavior, this research model considers social bonding and bridging that are divided by social capital. Design/methodology/approach An AMOS analysis based on survey data from 223 SNG users indicated that SNG with greater altruism enhance social capital (social bonding, social bridging), which is related to the user’s satisfaction and the continuance intention of SNG. Findings Social bonding is positively related to the user’s satisfaction with SNG. In other words, social bridging positively affects the continuous usage intention of SNG. These findings help managers in developing and implementing altruistic relationships and social capital for continuous usage of SNG.
