In 2010, the number of registered vehicles reached almost at 17.48 millions in Korea. This dramatic increase of vehicles influenced to increase the number of traffic accidents which is one of the serious social problems and also to soar the personal and economic losses in Korea. Through this research, an enhanced intersection hazard prediction model by combining Genetic Algorithm and Artificial Neural Network will be developed in order to obtain the important data for developing the countermeasures of traffic accidents and eventually to reduce the traffic accidents in Korea. Firstly, this research has investigated the influencing factors of road geometric features on the traffic volume of each approaching for the intersections where traffic accidents and congestions frequently take place and, a linear regression model of traffic accidents and traffic conflicts were developed by examining the relationship between traffic accidents and traffic conflicts through the statistical significance tests. Secondly, this research also developed an intersection hazard prediction model by combining Genetic Algorithm and Artificial Neural Network through applying the intersection traffic volume, the road geometric features and the specific variables of traffic conflicts. Lastly, this research found out that the developed model is better than the existed forecasting models in terms of the reliability and accuracy by comparing the actual number of traffic accidents and the predicted number of accidents from the developed model. In conclusion, it is expect that the cost/effectiveness of any traffic safety improvement projects can be maximized if this developed intersection hazard prediction model by combining Genetic Algorithm and Artificial Neural Network use practically at field in the future.

The construction project is a complex undertaking involving multiple participants. Conflicts are inherently natural in the construction projects and subsequently, a success of projects mainly depends on how well to cope with the conflicts. In the past, courts usually took the position that the professional's exposure in damages for negligent performance of any of his/her duties would not extend to strangers to the contractual arrangement. However, courts today generally reject that rationale which was earlier in vogue and protect architects, engineers, and contractors from being liable to third parties. It means that the lack of privity of contract could rarely protect a profession in a suit alleging the negligence or professional malpractice in preparing plans or specifications. The main goal of this paper is to enhance the understanding of the legal aspect of privity and to provide the trend of no-privity disputes through the analysis of lawsuit cases during the last 40 years. On the base of the analysis, importance of the third relationship and the liability in construction disputes is presented.

Purpose - Recently actively growing franchise systems distribution channel system in which franchise headquarter compared with franchise occupies an important place in distribution channel. Due to this, franchise and franchise headquarter are interdependent on task and in this situation the goal they go after, motivation and objective are probably inconsistent. If so, possibility to participate goal setting process or operating activity of opposite side is becoming bigger and in the end conflict may generate. The purpose of this study is to examine the role of the supervisor's attitude and expertise as moderating factors in the relationship between goal-incongruity/coercive power/role-incongruity and the conflict perceived by franchisee. Research design, data and methodology - This study was intended to verify how the supervisor's attitude and expertise as moderating factors in the relationship between goal-incongruity/coercive power/role-incongruity and the conflict perceived by franchisee. In order to achieve the purpose of this study, some study models and hypotheses have been established through theoretical examinations. Then, using these scales, the researcher completed the questionnaire survey. To test our hypotheses, the survey was conducted from March 9, 2016 for 20 days by random sampling, The study was implemented through a descriptive survey method using a self-administered questionnaire. A survey of 124 restaurant franchisee across Seoul and Gyeonggi Province was performed. A total of 124 completed responses were analyzed. In this study, I used SPSS 22.0 to analyze data and did frequency analysis to see demographic, and general features of the respondents; also did exploratory factor analysis to examine the validity of the items of measurement. Factor analysis was first calculated at a minimum, the number of factors, principal component analysis used when variables are committed to maximising the information with (principle component analysis) and the rotation of factors were angry about the great variable factors than 1.0 by applying Varimax rotation. In addition, I used the value of Cronbach's (Alpha) to examine the reliance of questionnaire items, final analysis the reliability factor can be found both high reliability hayeoteumeuro exceeds over 0.6 and did Multiple regression analysis to test hypothesis and also did hierarchical regression analysis to examine moderating effect. Results - To analyze the proposed model, according to the analysis result, it was found that the influence of goal-incongruity, coercive power, and role-incongruity on the perceived conflict of franchisee is moderated by the supervisor's attitude and expertise. That is, the more the supervisor's attitude and expertise were positive, the more the conflicts of the goal-incongruity, coercive power, and role-incongruity were decreased. It also confirmed previous research's finding that goal-incongruity, coercive power, and role-incongruity positively influence on the conflict. Conclusions - According to the results of this research which reduces the conflict of franchise from the in consistent goal; coercive power, and inconsistent role of superiors, it provides very important implications for franchise headquarter which has franchise system and also give them some suggestion about how to recruit superiors and what kind of training may be fit for the superiors.

The purpose of this study is to identify the factors influencing conflict transition through the conflict transition process experienced by college graduates with early careers. The participants of this study were in-depth interviews with a total of 8 young people aged 25-34 who graduated from college and found their common subjects in all cases. As a result, the topics such as 'lack of recognition and compensation', 'unfairness of supervisor', 'characteristics of job (interdependence, autonomy)' were derived. 'Lack of recognition and compensation' brought about a sense of skepticism about the idea that even though they worked hard, they could not be recognized. And it caused a conflict transition. When the participants felt the 'unfairness of the supervisor', the task conflicts were further amplified and it transfer to relationship conflict. Among the characteristics of 'job characteristics', when highly interdependent occupations were carried out, conflict transition was shown and conflict levels were high. On the other hand, the work environment with job autonomy showed job satisfaction and did not show conflict transition. This study has an academic significance in that it revealed the types of conflicts and conflict transfer factors experienced in early career status of college graduates. In addition, this research have the practical implications to improves the participants' understanding of the conflict transfer through actual scene in the workplace.

The topic of school community is considered very important in Christian education because the Christian religion is based on relationships. However, the studies on school community in Christian education are insufficient. Therefore, this study intends to explore the characteristics of school communities in Christian elementary school through descriptive approach. For this, data was collected through a ten-week participant observations and ten-time interview with the teachers, students, and parents, and artifacts collection. The result of the analysis, students were growing up with experiencing inner conflicts when they have a good relationship with their friends as a member of one community. This study gives suggestions to Christian school and public school communities as follows. First, studies on Christian schools' community have to be based on the Christian worldview. Second, The community of justice needs to be included in Christian school communities. Third, Christian school students experience continuous inner conflicts when practicing Christian values, thus the classroom community needs to be a place where students can talk about it openly. Fourth, public schools only consider the abilities to cultivate community competence, but it needs to apply the Christian school community where it is comfortable and acceptable to reveal weakness. In this way, the community will become a more humanistic environment.

Since death is an extremely subjective and unique experience, if we take into account the lack of understanding about death due to the difficulty in methodology, it is very important to try to understand the subjectivity of death. In this respect, Q-methodology that explains and shows the respondent's subjectivity by objectifying his subjectivity is employed as a solution to the questions in this study. Therefore, the purpose of this study was to provide data on how medical personnel should treat their patients, when it comes to death : by finding out the opinions of those who are being treated, namely the patients, and those who are providing the treatment, namely the medical personnel. It also by examined the characteristics and relationships between these two groups on attitudes to death. The results of this study show that medical per sonnel have two(fate-receipient, reality-oriented) types of response and patients have three (religion-dependent, science-adherent, sardonist) types. Medical personnel saw patients as having three (life-attached. traditionalist, death-rejector) types of response and to patients saw medical personnel as having two (rationalist, humanist)types. The relationship between the above-mentioned types will be examined in a coorientation model, the subjectivity of the medical personnel and the patient toward death indicates a relatively high understanding between the two groups under the great proposition of 'death'. Therefore, in their relationship with people who are facing death, the provider of care, namely the medical personnel, should identify the subjectivity of the patient before approaching them. By doing this, they can minimize the conflicts they might experience in establishing a therapeutic relationship, reduce suffering, and help the patient in greeting a more comfortable death. Throughout the study, Q-methodology expands our understanding of coorientation model that has only been approached with R-methodology. This study confirmed Q's potentiality and its validity in human subjective matters.

Background: The current lack of the number of nurses and high nurse turnover rate leads to major problems for the health-care system in terms of cost, patient care ability, and quality of care. Theoretically, burnout may help link emotional labor with turnover intention. The purpose of this study was to investigate the mediating effect of burnout in the association between emotional labor and turnover intention in Korean clinical nurses. Methods: Using data collected from a sample of 606 nurses from six Korean hospitals, we conducted a multiple regression analysis to determine the relationships among clinical nurses' emotional labor, burnout, and turnover intention, looking at burnout as a mediator. Results: The results fully and partially support the mediating role of burnout in the relationship between the subfactors of emotional labor and turnover intention. In particular, burnout partially mediated the relationship between emotional disharmony and hurt, organizational surveillance and monitoring, and lack of a supportive and protective system in the organization. In addition, we found that burnout has a significant full mediation effect on the relationship between overload and conflicts in customer service and turnover intention. Although the mediating effect of burnout was significantly associated with the demands and regulation of emotions, no significant effects on turnover intention were found. Conclusion: To reduce nurses' turnover, we recommend developing strategies that target both burnout and emotional labor, given that burnout fully and partially mediated the effects of emotional labor on turnover intention, and emotional labor was directly associated with turnover intention.

The purpose of this study was to investigate the convergence relationship between the clinical practice stress and professional identity of 171 dental hygiene students from 3 university in Jeollanam-do area. The data were analyzed using SPSS WIN 18.0 program. Professional identity was negatively correlated with clinical practice training environment(r=-0.352, p<0.01), clinical practice work burden(r=-0.185, p<0.05) and conflicts with patients(r=-0.181, p<0.05). The convergence factors influencing professional identity were clinical practice training environment(${\beta}=-0.261$), aptitude(${\beta}=0.238$), advice from others(${\beta}=-0.186$) and clinical practice unsatisfied(${\beta}=-0.176$). The regression model explained 23.7% of professional identity. Therefore, it is necessary to develop a program for the smooth labor supply by understanding the relationship between clinical practice stress and professional identity in dental hygiene students.

Governance can be defined as a concept that encompasses a series of processes including partner selection as well as control and coordination of collaboration to achieve common goals. The study examined efforts to mitigate the risks of opportunistic behaviors into partner selection, partner relationship, control mechanism, and conflict management. For cases that have achieved commercialization outputs with the participation of SMEs, data was collected and analyzed such as interviews with project managers and case records for seven months from October 2016. According to the analysis result, as the complexity increases, such as multilateral cooperation for the development of finished products, cooperation with a trusted partner rather than a partner who can perform a task well was preferred, and the process control was put ahead of the output control. Regarding the partner relationship, the relationship between the owner and the agent differed according to the point of view, and there was a lack of clear allocation of authority and responsibility as well as a reward for the result. In terms of the conflict management, most emphasis was on resolving conflicts or difficulties, and no attempt was made to utilize the positive aspects of the conflict. The structure of most industry-university-institute cooperation organizations is simply composed of the host and participating organizations, and the management regulations should be amended for companies, that put actual funds and use the outputs, to have the authority and responsibility as the owners, and be allowed to use the governance elements appropriately to take the lead as consumers.

Purpose - The study analyzed 90 online firms worldwise and observed them for ten years to investigate their investments and firm performance variabilities. This study attemped to verify the existence of agency problems in online firms. Through this, the paper intends to expand the scope of research in the fields of investment and firm value both empirically and in theory. This study also attempted to supplement the insufficient logic of previous studies by analyzing the relationship between investment and profitability. Design/methodology - In this study, the investment is subdivided into over-, under-, and neutral investments, and an empirical analysis of the firm performance was conducted. As investment generally has long-term effects, the impact of a firm's investment on future firm performance and variabilities in firm performance was considered over the short-and medium-term period. Findings - It was found that there was a negative relationship between firms with an overinvestment and future firm performance. Underinvestment has no clear statistically significant results on firm performance. This implies that overinvestment causes more reduction in future firm performance than underinvestment. It was also found that underinvestment and overinvestment significantly increased the variability of firm performance. A positive significance was found between under- and over- investment with a variability of 3 years and overinvestment with a variability of 4 years in the future. A negative relationship was found between neutral investment propensity and future performance variabilities. Neutral investment has less effect on the future performance variability of a firm than a firm's overinvestment and underinvestment. For online firms, underinvestment and overinvestment have a greater effect on the firm's future performance variability than neutral investment. Originality/value - The agency theory predicts that information asymmetry and adverse selection problems exacerbate conflicts of interest among stakeholders, thus firm performance. The study contributed to accumulating research on online firms that are currently underexplored by analyzing the investment behavior of major firms in the online industry.
