The construction industry is an industry in which skilled construction workers should be secured and trained because of the quality and productivity of buildings, but the negative image makes it difficult to supply and demand skilled construction workers. In response, this study derived the factors influencing the intention of transferring construction workers to other occupations and investigated ways to improve the prevention of leaving other occupations by age of construction workers. The factors influencing the turnover of construction workers have also been derived, and work overload, salary, workplace stability, and employment competitiveness have a significant impact on the intention of new employees to change jobs. According to a survey on ways to improve the prevention of leaving other jobs, those in their 20s and 30s are "improving working conditions, such as providing holidays, paying overtime, compliance with working hours," and those in their 50s and 60s.

This study was conducted to assess the bone mineral density (BMD) and the anthropometric measurements, life style, and other environmental factors affecting BMD in Korean adolescents. Subjects were 167 high school students (83 male students, 84 female students) in Seoul. BMD was measured in the lumbar spine (LS), femoral neck (FN), femoral trochanter (FT), and Ward's triangle (WT) by dual energy x-ray absorptiometry (DEXA). The questionnaire was used to assess the anthropometric measurements, life style, and other environmental factors. Bone mineral density of LS, FN, FT and WT were 0.967, 0.960, 0.795, $0.761 g/{\cal}cm^2$. The BMD of LS was not different by sex but the male students's BMD of FN, FT and WT were higher significantly than the female students (LS: 0.976 vs. 0.958, FN: 1.040 vs. 0.880, FT: 0.842 vs. 0.749, WT: 0.827 vs. $0.695 g/{\cal}cm^2$) Female students's BMD of LS, FN, WT, and FT was positively correlated with weight but male students's BMD of WT was not correlated with weight. The factors such as the life style, activity and exercise have significant influence on BMD. This study confirms that the major factor affecting BMD was body weight and the factors such as the life style, activity and exercise is related to accumulation of BMD. The classification of sexual characteristics is needed for further studies on BMD of adolescents.

The purpose of this study was to illuminate the ways to im-prove the level of life satisfaction of the elderly who chose or happened to live at paid facilities by examining some of factors such as individual family social support and facility related el-ements that would influence their life satisfaction. The interview outcomes came out in three main discussions. First the general characteristics of the participating elderly appeared to be that most of them were ver7y elderly relatively highly educated females and religions and the rate of being ill was high. And a half of them considered themselves as heal- thy people and the other half as unhealthy. Secondly in view of statisticsal results the level of their life satisfaction was influnced by their individual family and facillity related factors. As far as their individual related factor are concerned the level of one party's life satisfaction was relative-ely higher than that of other's when the person is female had religio presumed oneself as in healthy and good physical condition. And when participating member keeps good relation-ship with his or her own children the level of the person's life satisfaction was only slightly higher than other elderly group who did not have good relationship with their children. There were no other significant statistical differences on the level of their life satisfaction related to the social support factors between those two group. Thirdly the level of the elderly's life satisfaction was influe- nced in the order of folldwing factors: (1) the quality of facility living condition 2) the commitment of ownership of the organization (3) the elderly residents' own education level (4) the elderly's own subjectivel health condition and (5) the sex of the individuals.

Social media is an emerging issue in content services and in current business environment. YouTube is the most representative social media service in the world. YouTube is different from other conventional content services in its open user participation and contents creation methods. To promote a content in YouTube, it is important to understand the diffusion phenomena of contents and the network structural characteristics. Most previous studies analyzed impact factors of contents diffusion from the view point of general behavioral factors. Currently some researchers use network structure factors. However, these two approaches have been used separately. However this study tries to analyze the general impact factors on the view count and content based network structures all together. In addition, when building a content based network, this study forms the network structure by analyzing user comments on 22,370 contents of YouTube not based on the individual user based network. From this study, we re-proved statistically the causal relations between view count and not only general factors but also network factors. Moreover by analyzing this integrated research model, we found that these factors affect the view count of YouTube according to the following order; Uploader Followers, Video Age, Betweenness Centrality, Comments, Closeness Centrality, Clustering Coefficient and Rating. However Degree Centrality and Eigenvector Centrality affect the view count negatively. From this research some strategic points for the utilizing of contents diffusion are as followings. First, it is needed to manage general factors such as the number of uploader followers or subscribers, the video age, the number of comments, average rating points, and etc. The impact of average rating points is not so much important as we thought before. However, it is needed to increase the number of uploader followers strategically and sustain the contents in the service as long as possible. Second, we need to pay attention to the impacts of betweenness centrality and closeness centrality among other network factors. Users seems to search the related subject or similar contents after watching a content. It is needed to shorten the distance between other popular contents in the service. Namely, this study showed that it is beneficial for increasing view counts by decreasing the number of search attempts and increasing similarity with many other contents. This is consistent with the result of the clustering coefficient impact analysis. Third, it is important to notice the negative impact of degree centrality and eigenvector centrality on the view count. If the number of connections with other contents is too much increased it means there are many similar contents and eventually it might distribute the view counts. Moreover, too high eigenvector centrality means that there are connections with popular contents around the content, and it might lose the view count because of the impact of the popular contents. It would be better to avoid connections with too powerful popular contents. From this study we analyzed the phenomenon and verified diffusion factors of Youtube contents by using an integrated model consisting of general factors and network structure factors. From the viewpoints of social contribution, this study might provide useful information to music or movie industry or other contents vendors for their effective contents services. This research provides basic schemes that can be applied strategically in online contents marketing. One of the limitations of this study is that this study formed a contents based network for the network structure analysis. It might be an indirect method to see the content network structure. We can use more various methods to establish direct content network. Further researches include more detailed researches like an analysis according to the types of contents or domains or characteristics of the contents or users, and etc.

Purpose: The purpose of this study was to identify the effects of leader's emotional intelligence and nurse's own emotional intelligence on organizational commitment and organizational citizenship behavior. Methods: Data were collected by self-administered questionnaires from 346 clinical nurses, and analysed by the SPSS 18.0 program. Results: The Factors which influence organizational commitment were use of emotion of nurse (${\beta}$=.28), other's emotional appraisal of leader(${\beta}$=.25), regulation of emotion of leader(${\beta}$=.16), other's emotional appraisal of nurse(${\beta}$=14). These factors explained 36.7% of organizational commitment. The Factors which influence organizational citizenship behavior were other's emotional appraisal of nurse(${\beta}$=.25), use of emotion of nurse(${\beta}$=.24), regulation of emotion of nurse(${\beta}$=.23), use of emotion of leader(${\beta}$=.20). These factors explained 43.6% of organizational citizenship behavior. Conclusion: The results of this study can be used to develop hospitals' management strategies for enhancement of nurses' organizational commitment and organizational citizenship behavior.

The main purpose of this study was to develop a new method for evaluation of stream naturalness in order to appraise and prescribe for streams effectively in the process of ecological restoration of stream corridors. The results are as follows : 1) For this purpose six factors were selected on considering the spatial axes of stream corridor variation and total 20 descriptors about the physical structure were selected. 2) The calculation of S.N.I. for each segment was consisted of three steps, such as calculation of S.N.I.s of the individual descriptors, averaging all the descriptors's for each factor, and finally averaging the factors's for the Total S.N.I. 3) The evaluation unit was decided to be 100m size. The score system ranging 1~5 was adopted. Weighting parameters of factors were unified with each other. 4) A GIS model was adopted for classification, calculation, querying, analysing, and presenting S.N.I. information. And the format of S.N.I. maps including statistical graphs and other spatial watershed information was designed for the GIS odel. The naturalness of stream corridor was was investigated by the naturalness of habitat, and assessed by the descriptors focused on physical structure, therefore the S.N.I. can manifest prescriptions for restoration of the stream corridor. On the other hand because some evaluation factors such as water quality, water volume, fauna, flora, functions of stream exosystem has been excluded, S.N.I. could have some limits on representing the full aspects of stream naturalness. This evaluation method is hypothetical one, so it would be investigated through iterative applicatons.

The subjects for this study consisted of 301 Korean-American students in grades 6 to 12. Findings of this study showed that most of the risk factors in all domains demonstrated a strong relationship to the use of alcohol, tobacco, and other illicit drugs. In the community domain the most common risk factor was "laws favorable toward drug use"(60.2%); this risk factor increased the odds of substance use by approximately 3 times. The protective factor, "opportunity for positive involvement" in school domain reported by 82% of the sample decreased the probability of substance use by 3 times. The percentage of students "resilient" on all protective factors in the family domain was much lower than that of protective factors in other domains. The strongest predictors of substance use were shown in the peer-individual domain.

This study compared institutionalized children with at home children regarding characteristics of emotional intelligence and self-esteem, and the relationship between the two. The participants of this study were 62 institutionalized children and 98 children reared at home, residing in an undisclosed city. Major findings of this study were as follows. First, the institutionalized children had a lower level of self-esteem and emotional intelligence than children at home. Second, the relationship between self-esteem and emotional intelligence was significantly different between institutionalized and at-home children. Third, in case of institutionalized children, ‘other-regulation and self-expression’ among the emotional intelligence factors was the strongest predictor of ‘scholastic competence’ among self-esteem factors. In contrast, for the at-home children, ‘other-regulation and self-expression’ among the emotional intelligence factors was the strongest predictor of ‘social acceptance’ among self-esteem factors.

Coating performance of various coating systems including chlorinated rubber and epoxy/urethane used most for steel structures of highway in Korea, was evaluated by exposing test specimen to complex deterioration factors such as ultraviolet ray, moisture, freeze-thaw cycle and salt. Deteriorated specimens were evaluated by chalking and rust grades according to ASTM, and measurement of color differences and adhesion. In overall coating performances such as corrosion resistance, photochemical stability, and adhesion, ceramic/ urethane, moisture-curable urethane/ urethane, etc. were superior. As for other coating materials tested in this study, superior materials against certain deterioration factors may be inferior against other factors. Accordingly, in order to select suitable maintenance coating materials for the use, it is thought that investigation of suitability through experiment should precede selection of materials, especially for unusual coatings or paints.
