Formal Safety Assessment (FSA) has been mostly implemented on the hardware aspects of vessels. Although there are guidelines regarding human error FSAs, there have not been many assessments in such areas. To this end, this study seeks to use precedent studies for the safe operation of DP vessels, conducting an FSA regarding human error of DP LOP (Loss of Position) incidents. For this, the study referred to precedent studies for the frequency of DP LOP incidents caused by human errors, adding the severity of LOP incidents, and then applying them to the Bayesian network. As a result, the study was able to confirm that among DP LOP incidents caused by human errors, the drive-off from skill-based errors was 74.3% and the drive-off from unsafe supervision was 50.5%. Based on such results, RCOs (Risk Control Options) were devised through a brainstorming session with experts coming up with proposals including providing mandatory DPO training, installing DP simulator on the vessels, drawing up measures to understanding the procedures for safe operation of DP vessels. Moreover, it was found that mandatory DPO training is reasonable in terms of cost benefits and that while installing a DP simulator is not suitable in terms of cost benefits, it can significantly reduce risks when operating DP vessels.

건설공사비지수는 과거의 공사데이터를 바탕으로 신규공사의 공사비를 추정할 수 있을 뿐 아니라, 공사 수행 중 원가를 구성하는 비목의 가격이 상승 또는 하락할 경우 계약금액을 조정하는데도 활용된다. 국내의 경우 건설공사비지수는 주로 계약금액 조정을 위해 활용되고 있지만 계약금액 조정에 활용되는 지수의 경우 비목별 지수 산정시 건설원가의 변동을 적절하게 반영하지 못하는 문제점이 지적되어 왔다. 본 연구에서는 기존의 공사비지수 산정에 관한 선행 연구들을 비교 분석하고, 도로 건설공사 내역서의 분석을 통해 노무, 재료, 기계경비를 구성하는 주요 항목들을 중심으로 도로 건설공사비지수를 산정하는 방법론을 제안한다. 본 연구에서 제안하는 각 비목별 주요 항목의 투입 구성비를 활용한 지수산정 방법론의 적용을 통해서 건설원가의 변동을 적절히 반영하지 못한다는 기존의 문제점이 보완될 수 있을 것으로 기대된다.

In accordance with the aged society, oral health care for the elderly is considered important to maintain general health. Although the role of dental hygienists is essential for proper health management of the oral cavity, research on the care system for the elderly people's oral health and on the role of dental hygienists in the field of elderly welfare is still insufficient. Hence, the aim of this study is to investigate the status of Korean elderly welfare system and dental hygienists by comparing them with those in Japan, a precedent of aged society. First, we compared and investigated the Japanese long-term insurance system, which provides an institutional basis for a long-term care system for the elderly in Korea. Second, the elderly welfare law and care system, focusing on oral care, were examined. Lastly, in elderly care, we analyzed the distinctions between Korea and Japan regarding dental hygienists' role and scope of work. Taken together, as a precedent of aged society, Japan has shown well-specialized and systematic welfare for the elderly compared with Korea. With the development of the welfare system for the elderly in Japan, the role and the work scope of dental hygienists have been expanded to improve quality of life of elderly people, as a key professional for elderly oral care. Therefore, we should perceive the need for improvement of long-term care insurance and the expansion of dental hygienists' work in Korea. In conclusion, these results could be used as basic data for improving the elderly welfare system and developing dental hygienists in Korea.

In Korea, although the damage from disaster (flood and storm) is increasing, the early stage warning and countermeasure are not in operation rapidly. The research areas of transportation engineering arenot diverse, so once the road is flooded and interrupted, drivers, the system operators and managers are in panic, and nearby roads are in terrible traffic congestion. In case of Korea, the research of evacuation is highly needed, because it is very necessary and easy to apply in real field. In this paper, we establish the concept of transportation disaster prevention system and suggest the directions of it. In addition, based on this research, we choose one example of disasters and establish an example of the transportation disaster prevention system. Our goal is to make steps; prevention, preparation, countermeasure and restoration in the view of minimizing on social chaos and damages emphasizing aspect of transportation countermeasure. This research will be the good precedent of approach, analysis and countermeasure when the disasters are occurred, and a basis of transportation disaster prevention system and manual in Korea.

The purpose of this paper is on employees as internal customers and the critical role this group plays in the delivery of quality results. The set up of research model for verification was as follows. The research model was drawn as internal service quality level $\Rightarrow$ internal customer satisfaction $\Rightarrow$ enterprise outcome. Then, two hypotheses were established to the research model. Through the factor analysis and multiple regression analysis, the results are as follows. First, internal service quality level turned out to be affected indirectly through internal customers' satisfaction rather than a direct factor to affect the enterprise outcome. Second, internal customers' satisfaction was proved to be the most important factor for the enterprise outcome as ti was the intimate factor precedent to the enterprise outcome. However, there could be a variation of response according to the personal circumstances of respondents since the respondents were from different enterprises and consisted various job positions and age group. Namely it included a limitation of rather unaccurate resulting values because the transverse methods were performed for convenience though it needed a longitudinal research to accomplish the general purpose of this study.
