With the entry into the aging society, we are increasingly interested in wellness, and personalized medical services through artificial intelligence are expanding. In order to provide personalized medical services, it is difficult to provide accurate medical analysis services only with the existing hospital system components PM / PA, OCS, EMR, PACS, and LIS. Therefore, it is necessary to present the hospital system model and the construction plan suitable for personalized medical service. Currently, some medical cloud services and artificial intelligence diagnosis services using Watson are being introduced in domestic. However, there are not many examples of systematic hospital system construction. Therefore, this paper proposes a hospital system model suitable for personalized medical service. To do this, we design a model that integrates medical big data construction and AI medical analysis system into the existing hospital system components, and suggest development plan of each module. The proposed model is meaningful as a basic research that provides guidelines for the construction of new hospital system in the future.

In this paper, we discuss a service to give alarm in the case of emergency for the old and the weak by human behavior recognition in Intelligent Space. Our Intelligent Space consists of mobile robots, sensors and agents. And these components are connected to network framework. Agent analyzes data acquired from networked sensors and determines task of robots and a space to provide a service for humans. In our emergency alarm service, human behavior recognition service module analyzes accelerometer data obtained from body-attached human behavior sensing platform, and classifies into four basic human behavior such as walking, running, sitting and falling-down. For the old and the weak, falling-down behavior may bring about dangerous situations. On such an occasion, agent executes emergency alarm service immediately. And then a selected mobile robot approaches fallen person and sends images of the person to guardians. In this paper, we set up a scenario to verify the emergency alarm service in Intelligent Space, and show feasibility of the service from our simulation experiments.

Service-oriented computing offers efficient solutions for executing complex applications in an acceptable amount of time. These solutions provide important computing and storage resources, but they are too difficult for individual users to handle. In fact, Service-oriented architectures are usually sophisticated in terms of design, specifications, and deployment. On the other hand, workflow management systems provide frameworks that help users to manage cooperative and interdependent processes in a convivial manner. In this paper, we propose a workflow-based approach to fully take advantage of new service-oriented architectures that take the users' skills and the internal complexity of their applications into account. To get to this point, we defined a novel framework named JASMIN, which is responsible for managing service-oriented workflows on distributed systems. JASMIN has two main components: unified modeling language (UML) to specify workflow models and business process execution language (BPEL) to generate and compose Web services. In order to cover both workflow and service concepts, we describe in this paper a refinement of UML activity diagrams and present a set of rules for mapping UML activity diagrams into BPEL specifications.

In this study, we investigated the characteristics of the PCK components of pre-service chemistry teachers considered in the processes of developing performance assessment. Eight pre-service teachers participated in this study. After the workshop for performance assessment, they developed performance assessment through the planning, embodying and small group discussion step. Their activities were recorded and videotaped. Semi-structured interviews were also conducted. It was found that the PCK component considered in developing performance assessment individually was mainly the knowledge of assessment in science. The proportions of knowledge of curriculum, instructional strategies and students were found to be relatively low. The feedback on students' performance was not considered at all. The orientation to traditional assessment which emphasized on the objectivity of assessment, was stronger in the embodying step rather than in the planning step. During the planning step, the integrations among the PCK components mainly appeared with the knowledge of instructional strategies. However, they hardly appeared in the embodying and discussion steps. The main characteristics of the PCK in small group discussion were similar with those in the embodying step. Some PCK components were considered more in small group discussion, but most discussions were in the traditional perspectives.

This study investigated contents of mission statements for Strategic Management of hospitals in Korea and Japan. For the study, 44 tertiary care hospitals in korea, which were accredited by the Ministry of Health and Welfare, were selected. And 83 special functioning hospitals in Japan, which were approved by the Minister of Health, Labour and Welfare, were included. Both quantitative and qualitative analyses were conducted by classifying 5 components of the mission statement; market, service, philosophy, image, contribution. Findings from this study are as follow. First, hospitals in Korea emphasized image(93.2%) and philosophy(81.8%) components in their mission statements, whereas hospitals in Japan highlighted components of service(89.2%) and market(72.3%). In detail, mission statements of Korean tertiary care hospitals describe the components of hospital's image (93.2%), philosophy(81.8%), contribution(56.8%), market(22.7%) and service (18.2%) in order. On the other hand, mission statements of Japanese special functioning hospitals describe hospital's service(89.2%), market(72.3%), contribution(61.4%), image (49.4%) and philosophy(34.9%), respectively. Second, as results of Content analysis, there were some differences in mission statements of hospitals between two countries, and it is mainly from the divergences of standards for recognition of medical institutions, environmental factors, and different ways of mission statement description. For strategic hospital management, carrying out innovative restructuring organization or promoting of research and training for medical development is considered as a desirable approach. However, clear description of mission statement is more important and it is required for effective control and managing organization. And then the mission should be communicated within an organization so all internal members understand it and put their efforts to achieve the mission of organization. In conclusion, it is recommended that a leader and senior managers should re-evaluate its mission statement whether it reflects characteristics of an organization. In addition, a mission statement should be created or improved based on critical decision, as well as it should be clearly shared within an organization in order to become a future oriented organizations.

The EJB 3.0 specifications, which were improved in terms of performance and ease of development, were recently announced. Accordingly, for the EJB 3.0 application environment, developers generally prefer the gradual transformation of components whose performance must be improved to the complete transformation of all the EJB 2.1 components into EJB 3.0 components. Previous studies, however, did not consider the service of the application and did not ensure the compatibility and reusability of the components in the full replacement of EJB 3.0 due to the transformation using different specifications. This study proposed three transformation techniques that consider the service supported in the existing application, wherein the compatibility and reusability of the components are ensured in the case of the full replacement of EJB 3.0. The proposed transformation techniques are techniques for gradual transformation, such as direct transformation that directly connects components, indirect transformation that uses the EJB connector, and indirect template transformation wherein the template pattern is applied to the indirect transformation. The proposed transformation techniques were verified by comparing the reusability and processing capability of the components per second, and the standards for selecting a technique were provided based on the characteristics of the transformation into EJB 3.0 that were found in this study.

This study investigates the current features of social service provision system focusing on the core institutional traits of the system and community environment. Specifically, the study analyzes the differences in the contents and characteristics of social service provision, according to the community types, such as metropolitan area, medium size cities, and rural area. Also, the study explores the relationships among the three major subsystems in the social service provision system based on the types of financial provisions. Furthermore, the interaction effects between the community factors and financial traits on the relationships among sub- components in the service provision system are investigated. In this study other organizations, service users and public sector are regarded as three major sub-components in the provision system. The study utilizes the raw data from '2015 Social Service Demand and Provision Survey', which interviewed 4,100 social service organizations. Results from analyses show that the gap among metropolitan area, medium cites, and rural area is not so much bigger in the diverse provision features(e.g. the competition level, the major focus on the users, and policy demands on public sector) of provider-provision-organizations than in those of both of user-provision-organization and of market-way-organizations. User-provision organizations show the distinct differences in terms of the focus points on the users, while marketed organizations do in terms of the policy demands to the public sector. In rural area, user-provision organizations act like provider-provision-organizations whereas they do market-way-organizations in the urban area. Research findings show that the social service provision types utilizing market mechanism(such as user-provision, and market-way) are not so well fit into the characteristics of rural area.

In this research, a habitat model for Chinemys reevesii is suggested based on the components and variables of the Habitat Suitability Index which was determined through a series of literature researches, site surveys, and behavioral analysis. After reviewing the general habitat requirements, the site surveys(9 reservoirs) from July to December 2010, and the behavioral analysis of five Chinemys reevesii, the relationship between the behavioral and habitat use pattern was evaluated. According to the site surveys and behavioral analysis, the ecological core area(FK 50%) was about 0.96ha on average, the influence area(FK 90%) 4.22ha, and the home range was about $37.75{\pm}17.26m$ on average. As for the habitat use pattern of Chinemys reevesii, it travels through canals, and is influenced by the surrounding land uses. Also when there is a lack of food, the home range increases, and during hibernation, Chinemys reevesii prefers to be in an area within 1~2m range of water shores of fine textured soil and aquatic plants. After analyzing the information, the HSI standard was set and its components were determined as food, sunbathing and cover, aquatic environment, and spatial relationships. And the variables and the ranges of the components was determined as aquatic plant cover(0~49.81%), sandy area($3{\sim}13m^2$) and water velocity(0~60cm/s) etc. Lastly, plans and sections of the habitat model is provided designed according to the information from the researches, and problems to consider during habitat restoration was suggested in order to help understand about Chinemys reevesii habitat.
