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.

Purpose : The purpose of this study is to investigate the effect of strengthening program for improving the muscle strength and body function in rehabilitation of patients with stroke Methods : We found the 15 precedent studies at online portal site of "Korea education and Research information service" and found 5 precedent studies at "Pubmed". We analyzed and describe the total 19 studies involving national and international research. Results : The strengthening exercise was adapted to lower extremities and trunk muscle of participants and the isokinetic (concentric and eccentric) exercise was most of exercise type and then manual isometric exercise, functional activities, progressive task oriented resistance exercise, PNF pattern exercise was following. The studies reported that the strengthening program increased target muscle strength and improved balance capacity and walking function for the participants positively. Conclusion : Conclusionally the several strengthening program can be the intervention to increase the muscle strength without increasing spasticity for patients with stroke. We think that the strengthening of lower extremities an improve balance capacity and walking ability and it can use the intervention to change the quality of life in patients with stroke. More than 3weeks strength program might be effectiveness, in case of acute patients with stroke, the improving of muscle strength is available but need to study for improving balance and walking capacity more in the future.

이 연구에서는 2009 개정 교육과정에 의한 중학교 과학 교과서 27권에 제시된 삽화에 나타난 성역할 고정관념을 분석하고, 2007년 개정 교육과정에서의 과학 교과서 분석 결과와 비교하였다. 2009 개정 교육과정에 의한 교과서에서는 모든 학년에서 남학생의 등장 빈도가 여학생보다 높았으며, 이전 교육과정에 의한 교과서에 비해 삽화에 제시된 학생의 성별 등장 빈도 차이가 약간 증가하였다. 특히, 학습외 활동에서는 이전 교육과정에 의한 교과서와 마찬가지로 출판사에 관계없이 성별 등장 빈도의 차이가 컸다. 성인이 제시된 삽화의 경우, 남성의 등장 비율이 여성보다 높았으며 학생 등장 삽화에 비해 성별 간의 차이가 매우 큰 것으로 나타나, 이전 교육과정에 의한 교과서에 비해 별다른 개선이 이루어지지 않았다. 모든 출판사의 교과서에서 가정 활동에서는 여성이, 가정외 활동에서는 남성이 많이 등장하였고, 가정외 활동에서의 차이는 이전 교육과정에 의한 교과서보다 증가하였다. 또한, 대부분의 직업에서 남성의 비율이 높았으며, 교과서에 제시된 과학자는 대부분 남성이었다.

The present study is aimed to reconsider the time of installation and the purpose of the square footstone located at the center of the wooden pagoda in Hwangnyongsa Temple, based on related precedent studies. Precedent studies are divided into two streams of assertions: one is that the square footstone was to support the major pillars at the time of building and the other is that it was installed to store Buddhist reliquaries inside the central foundation stone after the wood pagoda burnt down in the Invasion of Mongol. Summarizing the grounds with which the precedent studies support their assertions, they are the relation with Gaseopbul Yeonjwaseok, the emerging time of the square footstone, repairing work at the level of reconstruction, additional enshrinement of general Buddhist reliquaries and so on. The present study reviewed the key grounds suggested in the previous studies regarding the square footstone. First, it was determined that the square footstone has nothing to do with Gaseopbul Yeonjwaseok, after looking into the timings of appearance, condition and shape in literatures. Rather, it was assumed that Gaseopbul Yeonjwaseok resembles a stone column. Next, the square footstone is assumed to be installed after the 4th year of King Kwangjong's rule because the wood pagoda was lost in fire in the 4th year of Kwangjong's rule and it had been left alone for 68 years until the repair work finished in the 13th year of King Hyunjong. It is assumed that repair works at the level of reconstruction had been twice in total, say, once during King Kyungmun and Hyunjong, respectively. Next, looking into the establishment of the general Buddhist reliquaries and the repair work during King Kyungmun, it was not common then to enshrine additional Buddhist reliquaries when repair work progressed and so there was not an additional enshrinement of Buddhist reliquaries after King Kyungmun. However, it is hard to decide that there was no repair work at the level of reconstruction at that time. Last, we can find a similar case to the square footstone of the wood pagoda in Hwangnyongsa Temple in the copper pagoda in Japanese Yaksasa Temple. In conclusion, it is assumed that the wooden pagoda in Hwangnyongsa Temple was lost to the fire in the 4th year of King Kwangjong's rule and thus the square footstone had been used as Jinho stone to protect Buddhist reliquaries and used as a propping stone for the major pillars after King Hyungjong.

본 연구는 공기업을 중심으로 다면평가제도의 선행요인이 평가효용성에 미치는 영향과 평가효용성이 조직성과에 미치는 영향을 파악하고 평가제도의 사전교육정도에 따라 평가효용성에 미치는 영향에 차이가 있는지를 알아보고 궁극적으로 피평가자가 인식하는 평가효용성이 조직성과에 어떠한 영향을 미치는지 4가지 관점에서 연구하였다. 연구 결과 선행요인인 평가자 신뢰성, 최고경영자의 지지는 평가효용성에 유의한 영향을 미치고 있으나 평가준거는 유의적이지 못하였다. 사전교육의 정도에 따라 선행요인과 평가효용성 간에 조절효과가 있는지를 검증한 결과 평가자 신뢰성은 조절효과가 있는 것으로 판명되었다. 그러나 평가준거, 최고경영자의 지지는 조절효과가 없는 것으로 나타났다. 결과적으로 본 연구의 평가효용성이 선행요인의 영향을 받아서 조직의 성과 즉, 조직몰입도, 직무만족도, 자기계발기회, 조직활성화에 직접 또는 간접적으로 영향을 미치며, 사전교육이 부분적으로 조절효과가 있는 것으로 확인할 수 있었다.

The purpose of this study was to identify the constructing factors and the hierarchy of the female clothing image evaluation made by male university students. 'rho instruments developed by the precedent study of In Hee Chung(1992) was used compare the female clothing image evaluation made by male university students with that by (emale students. The results were 1. 5 factor - modernity, grace, activeness, uniqueness, masculinity were found out as constructors of female clothing image evaluation made by male university student. 2. Eleven clusters were determinted to exist. The clusters classified as the main groups were 'modem and romantic image' and 'classic and straight image.'

This bridge was planed to be located in Geuk-rak river at south of Kwangju city. And it is very important to emphasis the beauty of bridge appearance. So Ive adopted unbraced tube arch type those linear beauty is elegance and simple. Actually, foreign bridges similar to this won various prizes for excellence of design. But there is no similar precedent in domestic highway bridge. therefore we intended to certify the security of this bridge through computational analysis. In this paper, approximate introduction of this bridge, design procedure and principal examination item is mentioned.

This paper presents a new 3-D ray tracing technique based on the image theory with newly defined ray tubes. The proposed method can be applied to indoor environments with arbitrary building layouts and has high computational efficiency compared to the precedent methods resorting to the ray launching scheme. It predictions are in good agreement with the measurements.
