Purpose: The purpose of this study is to create a checklist for each type of disaster and to suggest a method for establishing an appropriate response system and making accurate and rapid decision-making. Method: In order to derive checklist factors, previous case analyses (Tropical Storm Rusa (2002), Typhoon Maemi (2003), and Typhoon Chaba (2016) were conducted for typhoon disaster. Grouping was conducted to derive checklist factors by analyzing general status (climate and weather) information and characteristics by case. Result: The case study was divided into national level and county level. In terms of national unit, eight forecasts were included: weather forecast, typhoon landing status, typhoon intensity, typhoon radius, central pressure, heavy rain conditions, movement speed, and route. Local governments should reflect regional characteristics, focusing on the presence or absence of similar typhoons (paths) in the past, typhoon landing time, regional characteristics, population density, prior disaster recovery, recent disaster occurrence history, secondary damage, forecast warning system. A total of eight items were derived. Conclusion: In the event of a disaster, decision making will be faster if the checklist proposed in this study is used and applied. In addition, it can be used as the basic data for disaster planners' response plans in case of disasters, and it is expected to be a more clear and quick disaster preparedness and response because it reflects local characteristics.

오늘날 인터넷은 사용자에게 수많은 정보와 다양한 선택의 기회를 제공하지만, 사용자는 급속하게 늘어난 수 많은 정보 중에서 자신에게 유용한 정보를 찾는데 더 많은 시간을 투자해야만 한다. 이러한 문제점을 극복하고 좀 더 효율적인 인터페이스를 제공하기 위해서는 사용자들이 원하는 정보를 획득하기까지, 어떠한 탐색 과정을 거쳐 의사 결정을 내리는지에 관한 이해가 선행되어야 할 것이다. 따라서 본 연구는 웹 검색 결과를 소비하는 사용자의 정보 탐색 패턴과 이에 수반되는 인지 과정을 시선의 움직임을 통하여 분석하였다. 실험 결과 일반적인 글읽기 형태와는 차별된 시선의 움직임을 관찰할 수 있었는데, 대부분의 시선 이동 궤적은 직선이 아닌 도처에 걸쳐 흩어진 의미 단위로 드문드문 이동함을 알 수 있었다. 또한 각 의미 단위를 중심으로 진행성(forward) 도약과 역행성(regressive) 도약이 관찰되었고, 제목 ${\rightarrow}$ 내용 순의 세밀한 응시가 이루어진 이후 Click 여부가 결정되었다. 하지만 평균 Scan path 는 타이틀과 내용의 구분 없이 전체 화면 길이/너비의 50%를 넘지 못하여 축소된 Golden Triangle 형태를 보였다. 본 연구 결과는 웹 검색 결과에 대한 사용자 소비 경향의 특성을 파악하여 향후 좀 더 효율적인 소비를 이끌어내기 위한 인터페이스 설계 방향의 기초 연구로 그 의의가 있다.

본 연구는 소비자의 일상생활 행동을 다각적이며 심층적으로 파악하기 위한 하나의 방법으로 다양한 조사방법론을 활용하였다. 본 연구는 디지털 제품 선도 소비자(lead consumer)를 대상으로 구조화된 설문조사법 이외에 심층면접(In Depth-Interview), 쉐도우 서베이(Shadow Survey), 홈비지팅(Home-Visiting) 등의 방법론을 사용하였다. 즉, 일반 소비자와 선도 소비자의 일반적 특성을 파악하기 위해 질문지를 이용한 설문조사방법과 선도 소비자의 일상생활 행동, 행동의 원인, 행동의 결과 등을 심층면접, 쉐도우(Shadow) 관찰조사 방법, 가정 생활을 관찰하기 위한 홈비지팅(Home-visiting) 조사를 실시하였다. 그 결과 의사소통관련 행동은 가족 및 친구를 위한 활동, 정보처리관련 행동은 사회(3차집단)을 위한 활동, 엔터테이먼트 관련 행동은 개인을 위한 활동 목적이 많은 것으로 나타났다. 추후 연구는 상황(Situation)-차이(Gap)-사용(Use)이라는 Sense-Making Theory로 활용되어지며, 이러한 결과는 신상품 컨셉 개발을 위해 활용되어질 것이다. 그러나 본 연구는 견고한 이론적 틀 보다는 목적 지향적이며 실천 지향적 성격이 강하다. 따라서 추후 연구들은 체계적이며, 다학제적인 연구를 통해 조사방법의 체계를 다져야 할 것이다.

대기부품은 대기기간 중에 우발적 고장이 발생할 수 있으며(type I failure), 해당상황이 장기간 방치되는 것을 방지하기 위해 주기적인 검사를 하는 것이 일반적이다. 그러나 검사가 대기기간 중 발생한 고장을 확인할 수 있게 하는 반면, 검사를 시작할 때 대기하던 부품에 부하를 가하는 과정에서 고장을 유발할 가능성이 존재하며(type II failure), 검사시간동안 대기부품을 작동시킴으로써 열화에 의한 고장발생(type III failure)의 가능성을 증가시키는 효과도 존재한다. 이에 본 논문은 주기적 검사정책을 갖는 대기부품을 대상으로 세 종류의 고장 가능성을 확률적으로 고려하여 성능분석을 실시하였으며, 성능을 평가하는 척도로 극한가용성을 사용하였다. 특히 type III failure를 고려하는 것은 기존에 연구되지 않은 부분으로 본 논문의 기여점이라 할 수 있겠다. 또한 수치해석을 통해 가용성의 관점에서 전술한 세 가지 유형의 고장특성과 검사주기와의 관계를 파악할 수 있도록 하였으며, 그 결과를 통해 높은 수준의 신뢰성 확보가 목적인 대기시스템의 효율적인 운영을 위한 의사결정시 도움이 될 수 있도록 하였다.

The purpose of this study aimed to find the effect of self-esteem and communication competence on clinical practice stress of the Korean nursing students. A total of 198 nursing students participated in this study. Data collection was conducted through the use of questionnaires constructed to include the Rosenberg Self-esteem Scale, Global Interpersonal Communication Competence, and the Clinical Competence Scale. As a result, self-esteem, communication competence, and clinical practice stress of the Korean nursing students were found to be(Self-esteem: $3.4{\pm}0.57$; Communication competence: $3.5{\pm}0.42$; Clinical practice stress: $3.6{\pm}0.58$). Also, the nursing students with female(85.4%), experience of simulation on clinical training(72.2%) were found to have significantly higher clinical practice stress. Moreover, there were significant correlations between self-esteem and undesirable role model(r=.156, p=.029), communication competence and clinical practice stress(r=-.329, p<.001). The factors affecting clinical practice stress were communication competence, gender, satisfaction of clinical practice, and experience of simulation on clinical training. They amounted to 27.8% in clinical practice stress. The results indicate a need to develop effective teaching methods and learning strategies to decrease clinical practice stress of the nursing students.

LNG plant projects tend to be implemented in overseas owing to its characteristics, so their project management scheme is somewhat different from those of general projects. Value chain in a LNG plant project includes exploration/production of gases, physical liquefaction/chemical conversion processes, transportation and storage. Key factors in the chain include liquefaction process (including ultra-low temperature liquefaction) to convert natural gas into liquid materials or fuel, and Front End Engineering Design (FEED) package, as well as Engineering, Procurement and Construction (EPC) technology comprising control, operation and construction. Success of a complex LNG plant project implemented in overseas depends on decision-making process in project management. Accordingly, to develop a decision-making model in of plant construction, the study extracted none factors in project management by EPC stage and assessed importance of each factor. The result showed that items in both project management and project risk management are important. Especially, the study developed a decision-making model in the construction stage of a LNG plant project based on the project management factors and importance assessment. The developed decision-making model would lay groundwork in building a decision-making system in construction stage of project management.

Therefore the job satisfaction of organizational members should be raised to cut down on their turnover rate. The purpose of this study was to examine the relationship of the general characteristics of radiological technologist-turned hospital managers to their job satisfaction and turnover intention in a bid to identify factors affecting their job satisfaction and turnover intention. The major findings of the study were as follows: First, as for job satisfaction and turnover intention, the radiological technologist-turned hospital managers investigated got a mean of 3.00 and 2.79 respectively on overall job satisfaction and turnover intention out of five points. Their job satisfaction was slightly above the average (2.5), which indicated that they weren't gratified with their job. Their turnover intention was a little above the average as well, which implied that there was a tendency for them to seek another job. The findings of the study seem to suggest that the radiological technologist-turned hospital managers should make a new investment in their own future as their identity was thrown into confusion with age. They are expected to make a preparation for their future to open up a new chapter for themselves instead of being merely contented with their present position.

This study examines the effects of ethical education using CEDA discussion learning, on nursing professional self-concept, ethical dilemma and ethical decision-making confidence of nursing students. The participants were 57 third year nursing students from a nursing college in C city, and the data were collected from March 4 to May 13, 2019. Ethics education using CEDA discussion learning was conducted for 9 weeks, including 3 weeks of theoretical education and 6 weeks of CEDA discussion. Collected data were analyzed by t-test, one-way ANOVA and paired t-test using the SPSS WIN / 21.0. The results indicate that ethical education using CEDA discussion learning positively affects nursing professional self-concept (t=13.816, p<0.001), ethical dilemma (t=6.205, p<0.001) and ethical decision-making confidence (t=11.950, p<0.001). In addition, the self-concept of nursing professional, ethical dilemma, and ethical decision-making self-confidence are correlated, and nursing professional self-concept differs according to major satisfaction. Our results indicate a necessity to strengthen the ethics education of nursing college students, to help develop positive nursing professional self-concept and confident ethical decision-making in an ethical dilemma.
