Different from traditional development methodologies like waterfall model, the CBD (component based development) methodology relies on a building block approach in the design and development of information system. The audit procedure and checklist for the traditional IS development methodology are required to be modified to be suitable for CBD. This research reviewed IS audit guidelines for the existing development process and analyzed multiple projects that employed the by component based development process. For the purpose of this study, we chose a governmental project and a next-generation IS project of a financial agency as sample cases. By comparing existing IS audit checklists and items actually reviewed in audit projects, this study identified appropriate check items for the CBD-centric audit program. New items were proposed as additional items such as project control in management phase, usage case and conceptual model establishment, component evaluation and design, in implementation phase, and so forth. The result of the research provides new guidelines for the audit CBD projects for the purposed of increased efficiency and qualify of application development projects.

Outage areas can be transferred to adjacent feeders to restore power supply in case of the fault on the distribution system. Feeders in the small island or mountain area may not have backup feeders due to the low density of load. In this weakly meshed open loop system, BESS can be used as a backup feeder to improve reliability of power supply. This paper proposes a new network reconfiguration method for BESS based service restoration. Fuzzy decision making technique is adopted to deal with fuzziness of service restoration planning rules. Case studies using KEPCO real distribution system have been performed to verify feasibility of the proposed method.

One of the difficulties in using the current Boolean-based information retrieval systems is that it is hard for a user, especially a novice, to formulate an effective Boolean query. One solution to this problem is to let the system formulate a query for a user from his relevance feedback documents in this research, an intelligent query reformulation mechanism based on ID3 is proposed and the sensitivity of its retrieval effectiveness, i.e., recall, precision, and E-measure, to various input settings is analyzed. The parameters in the input settings is the number of relevant documents. Experiments conducted on the test set of Medlars revealed that the effectiveness of the proposed system is in fact sensitive to the number of the initial relevant documents. The case with two or more initial relevant documents outperformed the case with one initial relevant document with statistical significances. It is our conclusion that formulation of an effective query in the proposed system requires at least two relevant documents in its initial input set.

Objective : This case report show the effect of Dahuanghuanglianxiexin-tang on VulvoVaginal Candidiasis. Methods : According to disease pattern identification diagnostic system based on shanghanlun provisions, The author diagnosed Taeyang-byung kyeolhyung. The symptoms of VulvoVaginal Candidiasis were worsen when the patient had long sitting position and digestive problems. Therefore the patient treated with Dahuanghuanglianxiexin-tang for 3 months. The severity of Candida Vaginitis was evaluated by patient's subjective statements(Vaginal pruritus, Vaginal secretion, Burning sensation). Results : After the treatment, Level of syptoms decreased from Severe to Trace and Eliminated. Conclusions : Dahuanghuanglianxiexin-tang improved the symptoms of VulvoVaginal Candidiasis on this study. Although Dahuanghuanglianxiexin-tang is not an usual treatment for VulvoVaginal Candidiasis, the author could prescribe the medicine due to shanghanlun six meridian patterns diagnostic system.

Objective : This case report show the effect of Yonggyechulgam-tang on Panic disorder. Methods : The patient was diagnosed Panic disorder based on DSM-5. According to Shanghanlun six meridian patterns diagnostic system, the patient treated with Yonggyechulgam-tang for 4 months. The level of panic disorder was evaluated by VAS and BAI. Results : After the treatment, VAS and BAI decreased $10{\rightarrow}2$, $42{\rightarrow}4$ each. Conclusions : Yonggyechulgam-tang improved the symptoms of Panic disorder on this study. Although Yonggyechulgam-tang is not an usual treatment for Panic disorder, we could prescribe the medicine due to Shanghanlun six meridian patterns diagnostic system.

It is very important to allocate valuable resources efficiently when reconstructing buildings after earthquake damage. This paper proposes the use of a simple seismic retrofitting system to make buildings more resilient than the stiffer systems such as the shear walls implemented in Chile after the earthquake in 2010. The proposal is based on the use of steel chevron-type braces in RC buildings as a dual system to improve the seismic performance of multistory buildings. A case study was carried out to compare the proposal with the shear wall solution for the typical seismic Chilean RC building from the structural and economic perspectives. The results show that it is more resilient than other stiffer seismic solutions, such as shear walls, reduces the demand, minimizes seismic damage, gives reliable earthquake protection and facilitates future upgrades and repairs while achieving the level of immediate occupancy without the costs of the shear walls system.

While information technology has been advanced impressively, the issue of system underutilization has continued. Although TAM provides a theoretical and empirical model for explaining information technology acceptance, there exist some issues: lack of focusing task and organization. The present study examines the motivational factors influencing the beliefs about the system, in terms or the extended TTF (task-technology fit) model, to address the issues. For this purpose, an exploratory case study was conducted based on the data gathered from a Web-based survey. The present research proposes five propositions, based on the results of the case study and prior study findings, which can be used as a starting point fur future research.

In architectural planning, previous cases of similar spatial program provide important data for architectural design. Case-based reasoning (CBR) paradigm in the field of architectural design is closely related to the designing behavior of a planner who makes use of similar architectural designs and spatial programs in the past. In CBR, spatial graph can be constituted with most fundamental data, which can provide a method of searching spatial program by using visual graphs. This study developed a system for CBR that can analyze the similarity through graph comparison and search for buildings. This is an integrated system that is able to compare space similarity of different buildings and analyze their types, in addition to the analysis on a space within a single structure.
