Rationality only based on human experience and visuals takes huge toll on nation at the time of disasters. Accordingly, it is required to convert its system into national disaster-managing system based on governmental departments effective cooperation against catastrophic emergencies. Thus, this manuscript rejects empirical model of calamity measures and provides substituting prototype based on u-Gov which utilizes UT service from the developed countries' cases. Moreover, in order to provide nation's administrative services, the paper suggests alternative for politic issues which realizes a new incorporated control towel reflecting policies.

우리 삶에 있어 물은 필수적인 자원 요소이다. 우리나라의 경우 대부분의 강수량이 여름철에 집중되어 있어 원활한 용수공급 등의 문제를 해결하기 위해서는 댐 건설이 필요하다. 하지만 지구온난화에 따른 기후변화로 인해 국지성 호우 등 이상기후의 발생이 증가함에 따라 예상치 못한 자연현상으로 인해 댐이 붕괴될 가능성이 있으며, 붕괴시 댐에 저수되어있던 물은 하류 지역에 홍수를 일으키고 엄청난 피해를 발생시킬 수 있다. 본 연구에서는 김천부항댐을 대상으로 가상의 홍수발생에 의한 댐 붕괴 상황을 가정하였으며, 댐붕괴를 모의하기 위해서 요구되는 댐붕괴 매개변수 산정을 위한 경험공식인 Froehlich, Macdonal-Langridege-Monopolis 등 다양한 경험식을 적용하여 산정되는 댐붕괴에 따른 첨듀유출량의 변화 및 홍수파의 시공간적 변화과정을 분석하고자 한다. 댐붕괴 모의를 위한 기본모형은 HEC-HMS 모형을 적용하였으며, 댐붕괴에 따른 하류부 홍수범람 모의는 HEC-RAS 및 Geo-RAS의 범람도 작성기능을 활용하였다. 추가적으로 HEC-RAS에서 제공되는 2D 모델링을 통해 댐 붕괴로 인한 침수 지도를 생성한다면, 홍수 위험 위험 수준에 대한 통찰력을 제공하고 비상 조치 계획 개발에 기여할 수 있을 것으로 기대된다.

The Korean national curriculum for secondary school emphasizes scientific problem solving. In line with the national curriculum, many educational studies have been conducted in relation to science education. The objects of these studies were well-defined and well-structured problems. The studies were criticized for overlooking ill-defined and ill-structured problems. Some research has dealt with problem finding in ill-structured problems, which is related to creativity. There is a need for a study of scientific problem finding process in an ill-structured problem situation, because this study will help teachers wanting to teach scientific problem-finding in an ill-structured problem situation. The objective of this study was to conduct an empirical study on the scientific problem finding process in an ill-structured problem situation. One task of scientific problem finding in an ill-structured problem situation was assigned to 92 university students; thereafter, 32 of them participated in the research through interviews. Results indicated that the scientific problem finding process depended on initial clues and tentative solutions. Initial clues were affected by students' experiences, such as major classes, films, and novels. Tentative solutions were influenced by background knowledge of the tasks. Students screened information browsed on the Internet. They applied some standards for selection, particularly emphasized reliability standards, which are supposed to be studied in other contexts. All the students used assumptions to make their problems appear probable, which could be a useful tool to articulate.

This study investigated the ethical attitudes towards Do Not Resuscitate (DNR) among nursing college students. Data were collected from September to November 2022, involving 209 students in Jeonbuk Province. Analysis was done using SPSS WIN 25.0 with descriptive statistics and the χ²-test. Students generally agreed with respecting patient wishes, providing accurate information, and adhering to DNR guidelines. They supported treatment upon guardian request and maintaining aseptic principles for DNR patients. They showed neutral attitudes towards discontinuing mechanical ventilation upon family request, using all means to prolong life for patients with no chance of survival, the primary physician's DNR decision, etc. There was often opposition to the decline in medical team interest after DNR declaration. Significant differences based on DNR education experience were found regarding the use of all treatments for terminally ill patients (p=.028) and the need to advise if a co-worker treats a DNR patient without aseptic procedures (p=.014). Education on DNR situations and procedures is essential for accurate knowledge and high ethical competence.

Power plant engineering industry obtains EPC plan project and delivers results about electricity, measurement, machinery, and piping and so on. Its works are taken by projects. Although power plant engineering composes 2~5% of whole EPC project cost, it's one of the fundamentals because it affects process after planning step a lot. However, domestic power plant engineering companies' project performance ability is insufficient and there's a need for systematic performance. Thus, this study defined related factors of successful performance and analyzed the priority among them through analytical hierarchy process. All respondents recognized experience, knowledge, and communication as important factors. Administrators considered knowledge, experience, and communication. But hands-on workers considered experience, knowledge, human resources. Those who have experience in oversea project considered process, experience, human resources. However those who don't have experience in oversea project considered knowledge, experience, and communication. Recognition of important factors varies by the position and work experience of members.

Professional TBM Operator is in short supply worldwide, and insufficient construction experience of new personnel using TBM can lead to a decline in response capabilities when various construction risks occur. The fact that the TBM construction quality greatly depends on the skill and experience of the TBM operator, and the decrease in productivity due to insufficient skilled manpower, and the decrease in safety due to the decrease in skill level are frequently discussed problems in the TBM industry. To this end, several overseas companies and organizations have developed simulators, and a simulator is being developed in Korea. The International Tunneling Association is planning a comprehensive training, including classroom training, e-learning, simulator training and field training. Given the progress at home and abroad, TBM driver training and formal recognition of training through certification or licensing is expected to become the norm in the near future.

This analysis has been projected as a preliminary analysis to develop the therapy program for people who is suffering from stress disorder after car accident such as sense of fear or anxiety using virtual reality. The analysis verified the effect of driving scenario which is core technology of stress disorder program and of anxiety reduction training such as relaxation training through clients. The relaxation training has been tested to 8 people; 7 normal and 1 sufferer from car accident presenting them 3 different types of driving scenarios. As a result, relaxation training was effective but, it was not statistically good enough although it showed incensement of uneasiness by each different driving scenario. In spite of normal clients, it is interesting that anxiety lever after relaxation training using VR is lowered, but this result need to verify to client suffering real car accident.

The algebra is an important tool influencing on a mathematics in general. To make good use of the algebra, it is necessary to transfer from a given situation to a proper algebraic representation. But some research in related to algebraic word problems have reported the difficulty changing to a proper algebraic representation. Our study have focused on transformation and elaboration of algebraic representation. We investigated in detail the responses and perceptions of 29 Grade 7 students while transforming to algebraic representation, only concentrating on the literature expression form the problematic situations given. Most of students showed difficulties in transforming both descriptive and geometric problems to algebraic representation. 10% of them responded wrong answers except only a problem. Four of them were interviewed individually to show their thinking and find the factor influencing on a positive elaboration. As results, we could find some characteristics of their thinking including the misconception that regard the problem finding a functional formula because there are the variables x and y in the problematic situation. In addition, we could find the their fixation which student have to set up the equation. Furthermore we could check that making student explain own algebraic representation was able to become the factor influencing on a positive elaboration. From these, we also discussed about several didactical implications.
