It is show that increasing of aged and handicapped people requires development of Ubiquitous computing technique to offer the specialized service for handicapped-people. For this, we need a development of Context Awareness and Service Reasoning Technique that the technique is supplied interaction between user and U-environment instead of the old unilateral relation. The old research of context awareness needed probabilistic presentation model like a Bayesian Network based on expert Systems for recognize given circumstance by a domain of uncertain real world. In this article, we define a domain of disorder activity assistant service application and context model based on ontology in diversified environment and minimized intervention of user and developer. By use this context model, we apply the structure learning of Bayesian Network and decide the service and activity to development of application service for handicapped people. Finally, we define the proper Conditional Probability Table of the structured Bayesian Network and if random situation is given to user, then present state variable of Activity and Service by given Causal relation of Bayesian Network based on Conditional Probability Table and it can be result of context awareness.

This study analyzed the effect of individualism-collectivism propensity and social capital on participation activity as well as the effect of participation activity on fashion brands relationship orientation of social network service users. Also, this study investigated the difference in participation activity and fashion brands relationship orientation by participation level of social network service. A survey was conducted from October 1 to November 31, 2015, and 476 responses were used in the analysis. As results, the individualism-collectivism propensity was composed of vertical-horizontal individualism and vertical-horizontal collectivism. The social capital was composed of trust, norm, and network. Also, the participation activity was composed of personal interaction, consumer rights, information pursuit, interest pursuit, and economic pursuit. Vertical individualism positively affected information pursuit and economic pursuit, and horizontal individualism positively affected personal interaction, consumer rights, and information pursuit; in addition, vertical collectivism positively affected personal interaction, consumer rights, and interest pursuit. Horizontal collectivism positively affected information pursuit, but it negatively affected consumer rights. Consumer rights, information pursuit, interest pursuit, and economic pursuit of participation activity positively affected fashion brands relationship orientation. Also, there were significant differences in the participation activity and fashion brands relationship orientation by participation level. The study results provide useful information to the marketing strategies using social network service of fashion brands.

The paper investigates the determinants of firm's standardization activity in the Korean service industry. Standardization variables as dependent ones are standardization management at the firm level, domestic standardization activity, and international standardization activity. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, network, and firm's organization characteristics. We estimated the logistic regression model, using the data from 102 Korean service firms. The empirical findings are as follows. First, R&D intensity has a positive effect on international standardization activity, but not on the standardization management at the firm level and domestic standardization activity. Second, patent application has a negative effect on the standardization management at the firm level. Third, firm size doesn't have any influence on firms' standardization activities in the service sector. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.

The purpose of the study is to enhance the teaching competence for pre-service elementary teacher by using DGE in order to enhance SMK and PCK for them. To do this, we investigated the initial SMK and PCK for 23 pre-service elementary teachers, the reality of implementation activity of DGE and the change of SMK and PCK after quest activity by DGE. As results, 3 pre-service elementary teachers made errors which are misunderstanding a general angle as special angle, an excessive jump of logic and a circulation logic in the aspect of an initial SMK. In the aspect of contents of PCK, most of pre-service elementary teachers proposed teaching focused on the character using in the problem solving. And most of pre-service elementary teachers proposed teaching methods which are based on explanation, measurement and material manipulation. The reality of implementation activity of DGE was classified 4 cases which are a difficulty in understanding the concept of dynamics and embodying in DGE, an obsession about construction of $75^{\circ}$ and generalization, a difficulty in interpreting 'folding activity' mathematically and a good implementation activity. After quest activity by DGE, the case which is misunderstanding a general angle as special angle could be improved, but the others are not. And after quest activity by DGE, most of pre-service elementary teachers still proposed teaching focused on the character using in the problem solving in the aspect of contents of PCK, and some of pre-service elementary teachers added only teaching methods which are involving visual confirmation by GSP. From these results, we could extract some pedagogical implications helping pre-service teachers to reinforce SMK and PCK by DGE.

The purpose of this study was to examine the application of the Activity-based Costing(ABC) system to analyze the cost of nursing services in the delivery room in a major medical center.The results of this study are as follows;1. In order to calculate the cost of nursing activities, 67 activities of staff nurses on a delivery room were identified and classified as direct nursing activities(45.2%), the indirect activities(32.1%), general management activities(13.9%) and others(8.8%).2. Nursing cost in the delivery room was classified into activity cost(29.9%) and common cost(70.1%). Activity cost involved direct activity cost of staff nurses. The common costs were categorized into indirect activity & general management cost of staff nurses, management cost of the head nurse and activity cost of assistants.3. The final cost objects of nursing services in the delivery room were nursing service for women who had normal vaginal deliveries and nursing service for women who had preterm labor.The total cost of nursing service for a woman who had a normal vaginal delivery was 165,710 won (100.0%). The cost incurred through direct activity cost of staff nurses(58,242 won, 35.1%), indirect activity & general management cost of staff nurses (55,643 won, 33.6%), management cost of head nurse (16,211 won, 9.8%), activity cost of assistants (35,614 won, 21.5%).If the number of days of hospitalization was presumed to be 14 days, the total cost of nursing service for woman who had preterm labor would be 1,845,901 won (100.0%). The cost incurred by direct activity cost of staff nurses in the activity cost (341,349 won, 18.5%), indirect activity & general management cost of staff nurses in the common cost(779,002 won, 42.2%), management cost of head nurse(226,954won, 12.3%), activity cost of assistants in the common cost(498,596 won, 27.0%).In this study, the cost of the nursing services in the delivery room was calculated based on the ABC system. The results of this study showed that resources are assigned to the nursing activities in the delivery room and the mechanisms for assigning the cost of activities for nursing services.

The propose of this study was to investigate the influences of adolescent’s volunteer service activity on perception toward the elderly. The subjects of this study were 556 students who were selected at random from the second grade of high school in the city of Daegu. A questionnaire was used as survey method. Factor analysis and ANOVA were employed for data analysis and Scheffe test for post-hoc analysis. The main findings were as follow: First Adolescent’s perception toward the elderly was hardly different according to the adolescent’s overall volunteer service activity. The participation attitude, the whole participation time, and the voluntary participation time of the adolescent’s overall volunteer service activity had no effect on the adolescent’s perception toward the elderly. But adolescents who were high in the degree of the participation satisfaction with overall volunteer service activities had a more positive perception on social aspect of the elderly than those who were low in it. Second, adolescent’s who participated in volunteer service activities for the elderly showed a noticeable difference in their perception toward the elderly. adolescents who participated in volunteer service activities for the elderly, those who had a enthusiastic participation attitude over volunteer service activities for the elderly had a more positive perception of the family-relationship and social aspects of the elderly than those who had a passive participation attitude in it. Futhermore, adolescents who were high in the degree of the participation satisfaction over volunteer service activities for the elderly had a more positive perception of the family-relational and social aspect of the elderly that those who were low in it. Also adolescents, who spent a lot of time in whole and voluntary participation over volunteer service activities for the elderly, had a more positive perception of the social aspect of the elderly than those who spentless time.

This paper discussed about creativity and knowledge management variables as for effect factors on the management performance of IT service firms. Specially the mediation effects of knowledge management variables between the creativity and management performance were examined. To prove empirically the related hypothesis, the statistical analysis were based on the response from the 160 Korean IT Service firms. As an analysis results, it was found that the creativity of organizations was not the direct effector on the management performance. But the virtue of knowledge which are accumulated from knowledge management activity and shared in organizations was the direct effector. Also, the knowledge management activity is mediator on the in the relationship between the creativity and management performance. So this paper suggests that knowledge management activity and knowledge's virtue in the related the creativity in organizations are the important mediate factors for enhancement of IT service firm's performance.

The purpose of this study is to understand the characteristics of the mathematical modeling tasks and lesson designs developed by pre-service teachers based on the inherent awareness of mathematical modeling, considering the importance of creating a task to perform mathematical modeling activity and designing a lesson. As a result, the mathematical modeling tasks developed by pre-service teachers mainly presents an appropriate amount of information using real life contexts for the purpose of learning using concepts, and it showed a tendency to develop to the level of cognitive demand that required procedures with connections to understanding, meaning, or concepts. And most of the developed modeling task-based lessons showed a tendency to design warm-up activity, model-eliciting activity, and model-exploration activity. This result is due to the lack of experience of pre-service teachers in creating mathematical modeling tasks. Therefore, it is necessary to continuously provide opportunities for pre-service teachers to learn concepts or create mathematical modeling tasks intended for exploration according to various mathematical contents, thereby actively cultivating their ability to create modeling tasks in the course of training pre-service teachers. Furthermore, it is necessary to strengthen the expertise in mathematical modeling teaching and learning by providing opportunities to actually perform the mathematical modeling-based classes designed by pre-service teachers and to experience the process of reflecting on the lessons.
