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.

In this study, the illustrations in the 27 middle school science textbooks developed under the 2009 Revised National Curriculum were analyzed in the aspect of gender-role stereotype, and the results were compared with those of the 2007 Revised National Curriculum. The results of the analyses revealed that male pupils in the illustrations appeared more frequently than female pupils at all grades, and that the gender gap of pupils appeared in the illustrations slightly increased in comparison with those of the precedent curriculum. Similar to those of the precedent curriculum, the gender gap in other activities were particularly large regardless of publishers. In the illustrations of adults, the frequencies of male outnumbered female, and highly gender biased compared with those of pupils to mean that gender bias in the illustrations of adults were not improved at all. While the ratio of female was high in house works, that of male was high in outdoor activities regardless of publishers. The gender gap in outdoor activities increased in comparison with that of the precedent curriculum. Most occupations illustrated were male-dominated, and the majority of scientists were portrayed as male.

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.

This study, centering on public enterprises, has been conducted from 4 different perspectives such as grasping the effects that the factor precedent of the multi-rater feedback affects on the usefulness of evaluation and the effects that the usefulness of evaluation affects on the organizational achievement, checking on whether there is any discrepancy among the effects affecting on the usefulness of evaluation in accordance with the degree of advance training on the evaluation system, and being what kind of effects the usefulness of valuation that the appraised eventually understand affects on the organizational achievement. As result of the study, the factor precedent that are confidence of the appraisers and the support from CEO reasonably affected on the usefulness of evaluation, but the standard referred to evaluation was not reasonable. It became resultantly clear that the confidence of the appraisers held the effect of control from the verification of whether there is the effect of control between the factor precedent and the usefulness of evaluation in accordance with the degree of advance training. However, it turned out that the standard referred to evaluation and the support from CEO held no effect of control. As result, It was possible to confirm that the usefulness of evaluation in this study affects directly or indirectly to the organizational achievement such as organizational immersion, job satisfaction, self development opportunity, and organizational revitalization as influenced by the prior factors, and the advance training was partially effective on the adjusting effect.
