This paper describes the development of 3-D web graphic library for dynamic web graphic design. The 3-D web graphic library developed in this per supports creation of 3-D objects like cube and sphere objects, elimination of hidden line and surface, and the shading of diffuse and specular reflections. It provides, in drawing, perspective projection of an object depth first sort of multiple objects, and wire frame and solid models. It also supports texture mapping function for realistic and dynamic web application in application software. Each created 3-D object gives functions for the scaling, translation, and rotation of itself. It can be used for the development of dynamic web application software and the advertisement of information for business and tourism as a 3-D web graphic library engine. It is written in 'Java' language and runs on web browsers with Java virtual machine without any dependancy of client computer system.

Even though the success of the information system (IS) protect becomes a critical issue to an enterprise and there has been a lot of research about finding critical success factors of IS projects, the scope management for the success of IS protect has received little attention in the literature. The purpose of this research is to investigate the effects of the project scope management activities defined by PMI (Project Management Institute) on the performance of the information system project. The focus of this paper is on the project supplier's point of view. This study shows the priority of the scope management activities during the IS Project. The results show the different results depending on the types of the project clients and the project scale. This research reveals that the scope verification is important for the project supplier from the project process view, and that the scope planning/definition is important for the protect client from the project result view. It also shows different results comparing to the conventional recognition about project success. The research results show that the positive relationships between the project scale and the importance of scope management activities, and between the familiarity of suppliers and clients and the importance of the scope management activities. Through this research, we expect that the importance of the scope management in a project will be considered as an important issue, and that this research will lead to various detailed research about this issue.

This study investigated the relation between social worker's beliefs on the nature of scientific knowledge which has been classified objectivism and constructivism and social work practice. As an epistemological position, constructivism is based on a view of knowledge that differs from that of objectivism, which holds that knowledge exists "out there" as objective truth. The focus of this paper is a examination on epistemological beliefs of social worker and social work practice. This paper proves that social work's epistemological beliefs have an effect on the practice modes. This research indicates that social works have a higher constructivist veiws than objectivist veiws on the nature of scientific knowledge. And social worker who have a high level of objectivism show a positive determinative mode. It has suggested that the constructive theory offers useful epistemology to the social worker who should deal with the clients in uncertain situations. In conclusion, a social worker with a high level of constructivism use an approach that creats a more equitable relationship between social worker and client. This perspective will allows cliens to participate in the formulation of theories in practice.

Wireless sensor network (WSN) technology has been implemented using commercial off-the-shelf microcontrollers (MCUs), In this paper, we propose a simulation environment to realize the physical evaluation of FPGA-based node by considering vertically cross-layered WSN in terms of physical node device and network interconnection perspective. The proposed simulation framework emulates the physical FPGA-based sensor nodes to interoperate with the NS3 through the runtime infrastructure (RTI). For the emulation and interoperation of FPGA-based nodes, we extend a vendor-providing FPGA design tool from the host computer and a script to execute the interoperation procedures. The standalone NS-3 is also revised to perform interoperation through the RTI. To resolve the different time-advance mechanisms between the FPGA emulation and event-driven NS3 simulation, the pre-simulation technique is applied to the proposed environment. The proposed environment is applied to IEEE 802.15.4-based low-rate, wireless personal area network communication.

Objectives: We analyzed the reports of philosophical counseling and derived the characteristics of the questions that were administered in philosophical counseling. We also wanted to discuss if philosophical questions are necessary and applicable in Oriental medicine counseling. Methods: A systematic search of three Korean databases were performed. Case reports or case series that apply philosophical counseling to clients were included in this study (through June 27, 2019). We extracted questions and answers from the dialogue of each case. Extracted conversations between counselor and client were analyzed qualitatively. Results: Seven published articles with 17 cases were included and were analyzed for philosophical counseling. Philosophical questions have the following characteristics to help clients: (1) To clarify the phenomenon, (2) To identify subject and object, (3) To consider other people's perspective, (4) To review the premise, (5) To review the association relationship (6) To allow opportunities to think differently, and (7) To think of identity and values. Philosophical counseling and Korean medical counseling have commonalities in improving patients' resilience through logical conversation. The use of philosophical counseling in Korean medical counseling will maximize clients' philosophical resilience and the reparative power of nature. Thus, it is desirable to apply philosophical counseling to the practice of Korean medicine (KM). Conclusions: Through the qualitative analysis, we analyzed and categorized major characteristics of philosophical counseling. In the future, the possibility of using philosophical counseling should be explored in the KM practice.

The purpose of this research is to analyze the psychological dynamics of the characters in the novel 'vegetarian' of the Han Gang and the relationship patterns in the system by applying object relation theory. 'Vegetarianism' has already been analyzed and reinterpreted in various angles, but if you look at it from the object relationship theory and the systematic perspective, you can understand the inevitable history of the generation through psychological analysis and relation dynamics of the person. First, we will analyze the psychological dynamics of the characters by analyzing the meanings and exploring the meaning with the object relation theory and concept. The psychological analysis and the search process of the characters based on the theory are enough evidence for the counselor to reinterpret the life story of the client in the future clinical scene. In addition, in order to realize ethical but practical clinical education, the field of clinical practice will be extended when analyzing the characters using art. It is suggested that the meaning search through various character analysis needs to be accumulated culturally.

The purpose of this study is to explore the process for the elderly with palsy to solve conflicts with the elderly with dementia in day care center through the narrative therapy group work. For this, the researcher enacted the Narrative therapy group work on the 12 elderly with palsy for seven sessions, and analysed these data through qualitative case study method. The results of this study are as follows. First, the elderly with palsy became to recognize the elderly with dementia as 'the people suffering from dementia' rather than 'the problem', and tried to care them rather than to blame. Second, they became to recognize themselves as 'component people' rather than 'the victim'. Third, they grew intimate and collaborated with themselves. Fourth, they participated actively in day care center. It was discussed connection between these changes and narrative therapy skills, such as to separate problem from people, to respect client as expert for one's problem, to seek unique outcome. The recommendation is suggested that it is important to enlarge choice to participate for long-term care service consumer and to apply narrative therapy on the elderly.

IT outsourcing (ITO) is an integration of two firms-external vendor(s) and a client firm-IT resources by contract. According to resource-based view(RBV), three different resources-ITO vendor's resource, client firm's resource, and the relationship resource between two firms- may have an impact on ITO performance. However, there have been few previous studies considering all three IT resources simultaneously. There have been also few empirical studies in ITO context, which test Bharadwaj (2000)'s findings: 1) IT resources can be divided into tangible IT asset and intangible IT capability, and 2) only IT capability has an impact on the IT performance. Therefore we examined whether, in ITO context, all three different resources have a significant impact on ITO performance. Adopting the findings of previous IT studies, we also divided IT resource into IT asset and IT capability. To achieve this research objective, we analyzed 62 ITO cases of 45 companies being listed in Korean top 100 companies for recent 3 years. Also, we analyzed the data with the Partial Least Squares method. The results of this research lead to the following conclusions: First, only when partnership is high, ITO vendors' resource can have an influence on ITO performance. Second, only client firm's IT capability, not IT asset, is directly related to the ITO success. Third, a firm's IT capability can increase the partnership. Therefore, we concluded that 1) RBV is also an useful theory in ITO context, 2) Bharadwaj(2000)'s suggestion is valid in ITO context as well, and 3) the relationship resource is also important in ITO.

End-User Computing(EUC) is a rapidly growing phenomenon in organizations As EUC gets to be a major segment of information systems, it becomes more important to manage EUC effectively. This paper focuses on developing an integrative framework of EUC management in the contingent perspective. The characterstic of task for which EUC is implemented was considered as a contingent variable. Based on systematic review of previous research on success factors of EUC implementation, three generic variables for EUC management were identified theoretically, which were support, promotion and control. The contingent relationships between these three EUC management variables and EUC performance were reasoned and four hypotheses concerning these relationships were derived. A field study was undertaken to test the hypotheses. Data were collected from 83 End-Users belonging to Korean business organizations. Correlation analyses and Fisher's Z tests were employed to test the hypotheses. The results supported the hypotheses for the most part and gave implications and future research directions for the management for EUC.

In the Internet of Things (IoT), resource-constrained devices such as sensors are capable of communicating and exchanging data over the Internet. The IETF standard group has specified an application protocol CoAP, which uses UDP as a transport protocol, allows such a lightweight device to transmit data. Also, the IETF recommended the DTLS binding for securing CoAP. However, additional features should be added to the DTLS protocol to resolve several problems such as packet loss, reordering, fragmentation and replay attack. Consequently, performance of DTLS is worse than TLS. It is highly required for lightweight devices powered by small battery to design and implement a security protocol in an energy efficient manner. This paper thus discusses about DTLS performance in the perspective of energy consumption. To analyze the performance, we implemented IEEE 802.15.4 based test network consisting of constrained sensor devices in the Cooja simulator. We measured energy consumptions required for each of DTLS client and server in the test network. This paper compares the energy consumption and amount of transmitted data of each flight of DTLS handshake, and the processing and receiving time. We present the analyzed results with regard to code size, cipher primitive and fragmentation as well.
