Purpose: This study aimed to identify nursing competencies of outpatient nurses, to develop a tool to assess the same, and to verify the validity and reliability of the tool. Method: Preliminary items of the scale were developed based on a literature review and nurses' interviews. The tool's content validity was verified by an expert panel and by conducting a pilot study. Subsequently, to verify the validity and reliability of the scale, data were collected from 233 outpatient nurses from 7 certified tertiary hospitals. Data were analyzed using exploratory factor analysis, independent t-test, and internal consistency and correlation analysis. Result: The factor analysis revealed the following 9 factors for the 48 items of the scale: organizational management, customer orientation, personality and ethics, problem solving, nursing practice, interpersonal relationships, communication, crisis management, and professionalism. The Cronbach's α coefficient of the final instrument was .97. Conclusion: The tool developed in this study exhibited adequate validity and reliability. It was effective in reflecting the changing roles of outpatient nurses. Therefore, in future, this tool is expected to help improve outpatient nurses' competencies and nursing quality.

Korean construction industry has developed with national economy growth for a couple of decades. However, because of slump of real estate, the domestic construction industry was intimidated. In this situation, many construction company has no choice but to go abroad to find construction projects. However, almost small or medium-sized construction companies are very hard to operate their business because they have small funding ability and weak labor power. Therefore, this study aims to propose an assessment tool through analyzing risk factors of overseas construction projects for small or medium-sized companies by examining preceding research and interviewing industry experts. Weights of the risk factors are determined through the surveys of the industry practitioners. All of the data is configured into the assessment tool and this converts the quantitative information which leads to the optimal of strategies choice. This paper provides a quantitative measurement of possible performance and detailed assessment of each itemized risk factors. This assessment tool is qualified for industry experts so that it can safely be applied to the future projects. Ultimately, many small or medium sized construction companies will benefit from the tool proposed in this study to examine the potential of the overseas market expansion.

Interests on Service Level Agreement(SLA), an immanence operating tool for managing the level of the information system service objectively and qualitatively, were raised among IT outsourcing service providers, outsourcers, and operating departments. Yet, only a few domestic conglomerates adopted the SLA, and exact usage of the SLA is currently unknown. Because of the importance of the SLA between a service recipient and a service provider, the agreement is treated with high confidentiality. This raised the problems to organizations which are considering the SLA but lack in the concrete guide line to internalize SLA management process. This study provides the process model of implementation for SLA by conducting multiple case research. The sampled companies are currently implementing the SLA over 1 year of usage period. Factors were used to provide the managerial contribution for implementing the SLA. To analyse the case samples, in-depth interview method was conducted for each sampled company. As a result, if SLA can be used as an immanence managerial tool and can be actively implemented, it will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.

오늘날 웹은 가장 폭넓게 사용되는 기술이고 과거 몇 년 동안 웹은 여러 단계를 통해 진화되고 성숙된 기술이다. 특히 폭소노미, 태깅, RSS 등의 웹 인터페이스 기술이 사용자 중심적으로 발전, 변화하고 있다. 본 논문에서는 POI 정보 관리를 일반적인 구조적 관리 방법 뿐만 아니라, 태깅 기술을 적용하여 POI 정보관리를 위한 POIM(POI Management tool)를 개발한다. 사용자 중심의 POI 서비스를 위하여 사용자가 직접 POIM를 이용하여 특정 POI 객체들에 XML 기반 태깅 정의, 수정, 삭제 등을 수행하면 각 POI 객체들이 GML로 저장된다.

Most of existing expert systems developed for Web use CGI-based techniques and this frequently makes them suffer from the overburden of commercial Web servers, which deal with large-scale services. However, since HTML-based inference technique represents expert's knowledge by hyperlinks among HTML documents, the hypertext function of the Web can perform the inference efficiently in terms of time and space without the help of additional inference engines. In spite of such benefits, when the expert's knowledge is relatively large and/or complicated, the HTML-based inference technique has usually become to have a hard time of dealing with a lot of HTML documents because generation and management tasks of the numerous HTML documents would cause big trouble to the knowledge engineer. To resolve this problem, we developed an automatic generation and management tool for Web-based inference sites, called WeBIS. With this tool, a knowledge engineer can input and edit expert's knowledge using Expert's Diagram on the GUI(Graphical User Interface) environment and automatically generate hyper-linked HTML documents for Web-based inference from the Expert's Diagram.

Land-use change has an important role in the hydrologic characteristics of watersheds because it alters various hydrologic components such as interception, infiltration, and evapotranspiration. For example, rapid urbanization in a watershed reduces infiltration rates and increases peak flow which lead to changes in the hydrologic responses. In this study, a physical hydrologic model the soil and water assessment tool (SWAT) was used to assess long-term continuous daily streamflow corresponding to land-use changes that occurred in the Naesungchun river watershed. For a 30-year model simulation, 3 different land-use maps of the 1990s, 2000s, and 2010s were used to identify the impacts of the land-use changes. Using SWAT-CUP (calibration and uncertainty program), an automated parameter calibration tool, 23 parameters were selected, optimized and compared with the daily streamflow data observed at the upstream, midstream and downstream locations of the watershed. The statistical indexes used for the model calibration and validation show that the model performance is improved at the downstream location of the Naesungchun river. The simulated streamflow in the mainstream considering land-use change increases up to -2 - 30 cm compared with the results simulated with the single land-use map. However, the difference was not significant in the tributaries with or without the impact of land-use change.

The Korean halibut farming industry suffer from price instability and demand decrease due to various environmental and social issues. It is urgent to predict the appropriate amount of halibut production. However, it is not easy for employments working in the halibut farming industry to handle statistical tools in order to perform the prediction. In this paper, we implemented a Excel-based regression analysis tool that allows users to get a regression analysis result by just entering historical data in a sheet. Our tool will reduce workloads of employments working in the halibut farming industry by enabling them to perform a regression analysis with Excel on-the-fly. This study expect that by using the tool the halibut farming industry cope actively with the real-time change in the industry.

We address the problem of determining the optimal processing times and pallet/fixture allocation in Flexible Manufacturing systems in order to minimize tool cost while meeting throughput targets of multiple part types. The problem is formulated as a nonlinear program superimposed on a closed queueing network of the FMSs under consideration. A numerical example reveals the potential of our approach for significant cost saving. We argue that our model can be Integrated Into the process planning system of an FMS to generate efficient process plans quickly.
