IT projects need engineers with various backgrounds to cooperate to build an IT system that satisfy the requirements of users given a limited expense and time. Such diversity of team members and the complexity of task naturally involve considerable amount of conflict among team members. High level of conflict among team members is known to be detrimental to the performance of the team. The purpose of this study is to examine the reasons for conflicts among team members in IT projects and to check how the level of conflict affects the performance of a project and the satisfaction of the members of the project team. To test the relationship, a survey on 166 participants in IT projects was conducted. The reasons for conflicts in IT projects were categorized into five types. The level of ambiguity was found to have a significant correlation with the level of conflict. And the level of conflict, in turn, is found to have a significant effect on the degree of satisfaction among team members and the project results. Based on the research results, it is suggested that a clear definition of tasks and their boundaries is required to reduce ambiguity and thus, the level of conflict and improve the level of satisfaction of IT project team members.

The purpose of this study was to identify factors that have impact on taking care of dementia elderly people by careworkers. 212 careworkers participated in the survey. The data was analyzed by SPSS/WIN 18.0 program. The mean score of knowledge of dementia was 16.19, and attitude was 34.42, and the level of care performance for elders with dementia was 102.18. It was shown that the more positive attitude the careworkers had, the higher level of care performance occurred(r=.41, p<.001). As a result of analyzing the main factors affecting the level of care performance for dementia elderly people, attitude toward dementia(${\beta}$=.41, p<.001) and the level of education(${\beta}$=.27, p<.001) appeared to be significant explanatory variables, and this model's explanatory power was 27%. To settle a long-term care insurance successfully, the qualifications for careworkers are needed to be reinforced, and the ways to improve a positive attitude towards dementia elderly are also required to be come up with.

Two experiments were conducted to investigate into the effects of replacing maize with a mixture of cassava root and leaf meal (CRLM) on the performance of broiler chickens. In experiment 1, CRLM replaced 50 or 100 percent of maize in the control diet. In experiment 2, the 100 percent CRLM based-diet was fortified at a further 3 percent level with coconut oil. A total of 180, one-day old Shaver Starbro chicks, raised up to 49 days of age, were used. There were no significant (p<0.05) differences in final body weights, feed intake and feed efficiency between the control group and the group fed the diet in which 50 percent of the maize was replaced with CRLM. At the 100 percent level of replacement of maize with CRLM, however, final body weights, feed efficiency and carcass yields, were significantly (p<0.05) reduced. Dressing percentage and feed intake were not affected (p>0.05) by level of substitution of maize with CRLM. In experiment 2, when the diet in which all of the maize was replaced with CRLM was fortified with coconut oil at an additional 3 percent level, broiler performance improved and equaled (p=0.05) that obtained on the control maize diet. It was concluded the CRLM can replace 50 percent of maize in broiler diet without adversely affecting performance. However, for the complete replacement of maize with CRLM, it is necessary to further supplement such a diet with a high energy density ingredient if broiler performance is to be maintained.

In this paper, we arrange the concept of 'Green' in SCM after literature study of Green SCM and investigate causal relationships between influencing factors, practice level and environmental performance focused on Korean firms empirically and conduct path analysis for hypothesis test using partial least squares regression with bootstrap. Firstly, we divide influencing factors of Green SCM into environmental and organizational factors through the previous studies of innovation diffusion theory and environmental management theory, and then we selected 'uncertainty', 'competitiveness' as the environmental factors and 'top management support', 'perceived benefit', 'training' as the organizational factors. Secondly, we classify practice level of Green SCM into 'internal environmental management', 'green purchasing', 'eco-design'. Finally, we selected 'financial performance', 'environmental performance' as the organizational performance. We conducted a survey on the middle manager of manufacturing companies implementing SCM and an empirical analysis. The results of analysis show that there exist causal relationships between influencing factors, practice level, and environmental performance of Green SCM. We expect that the result of this study will suggest useful information to managers who are responsible for SCM to design and execute Green SCM in strategic perspectives.

Open loop geothermal heat pumps have great potential where the groundwater resources are sufficient. Performance of open loop geothermal heat pump systems is considered higher than that of ground source heat pumps. Head and power calculation of submersible pumps, heat pump units, and piping are numerically based on regression data. Results shows that the system performance drops as the water level drops, and the lowest flow rates generally achieve the highest system COPs. The highest achievable cooling system COPs become 6.34, 6.12, and 5.95 as the groundwater levels are 5m, 15m, and 25m. The highest heating system COPs also become 4.59, 4.37, and 4.20. Groundwater level and submersible pump selection greatly influence the system performance of open loop geothermal heat pumps. It needs to be analysed during the design process of open loop geothermal heat pump system, possibly with analysis tools that include wide range of pump product data.

The purpose of this study is to examine the dispute over creativity domain at schools in Korea. In other words, this study is to examine the creativity domain among all subjects, a group of high level performance, and a group of low level performance in creativity. Based on ability-differentiation hypothesis, correlation among 4 domains, correlation between divergent thinking variables of domain-generality and 4 domains of domain-speciality, and multiple linear regression have been computed. The results are opposed to the hypothesis. The group of low level performance is related to domain-speciality. The group of high level performance, however, has relationships neither domain-generality nor domain-speciality. Instead of differentiation between domain-generality and domain-speciality, the results support the domain-complementarity.
