Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

This study intends to develop an evaluation model which could be used as an effective tool for criticizing the model house of multi-family housing. The evaluation model has been developed based on the theoretical framework suggested by previous results of research related on hosing design, which comprises the following four components: 1) the paradigm of future home and life-style, 2) marketing effects of housing developer, 3) goals and principles of housing design, and 4) results of user-preference study. In this study, an evaluation model was suggested as a preliminary form which would be modified in detail after series of tests in the field. The evaluation model will be used provide standardized criteria for the quality of model houses, and eventually help to improve the quality of multi-family housing design by balanced information from theorist, user and developer.

Purpose: The purpose of this study was to develop a tool that measures the quality of nursing service, to measure the quality of nursing service perceived by consumers, and to identify the gaps between ideal and actual nursing services. Method: A questionnaire was developed and distributed to 300 people who had been hospitalized in one of six general hospitals with quality of nursing services in five provincial cities in Korea. For data analysis, the SPSS/WIN(ver 10.0) program was used. Result: The 20 attributes included in the instrument of quality of nursing service is abstracted into 2 factors: tangibility and intangibility. In quality analysis, 15 of 20 attributes are minus scores, meaning that those nursing services are perceived as generally low. However among the minus scores' attributes, only two attributes are significant statistically. Gaps between importance and performance of the nursing service exists in 19 among 20 attributes. Conclusion: Nursing service quality (performance-expectation) needs to be improved, and Gaps (importance-performance) reduced. In addition, a tool measuring nursing service quality has to be developed so nurses can deal successfully with the quality and gaps of nursing service perceived by consumers.

엔진 내구성시험(AMT : Accelerated Mission Test : 또는 임무 가속시험) 기법을 이용한 엔진 부품의 국산화에 따른 품질 보증 시험이 수행되었다. 엔진 내구성시험 기법은 엔진의 개발/구성품 개량, 부품의 기술변경에 따른 인정시험이나, 입증시험을 위한 시험방법으로 1976년부터 적용되기 시작하였다. 본 논문은 국내에서 수행되었던 시험경험을 바탕으로 아직 국내에서 생소한 내구성시험에 대한 개념, 시험수행 절차와 방법 그리고 시험평가 수행 방안을 제시하였으며, 이를 통하여 엔진 부품의 국내 개발/생산시 품질인증을 위한 시험/평가 가능성을 제시하였다.

A cutting fluid can improve machining quality and tool life by maintaining the tool toughness and by providing a lubrication effect to reduce the friction between the chip and tool interface. Although liquid nitrogen as an environmentally safe coolant has been widely recognized in cryogenic machining, its function as a lubricant is plausible due to its chemical inertness, physical volatility and low viscosity. Since a reduced friction is a direct witness of the lubrication effect from a tribological viewpoint, this paper presents an evaluation of the apparent friction coefficient on the tool-chip interface in cryogenic cutting operations to prove and characterize the lubricity of LN2 in cryogenic machining. The mathematical approaches have been formulated to derive the normal and frictional forces on the tool-chip interface for the oblique cutting tests.

Service quality is, unlike goods quality, an abstract and elusive term. However, quality is very important to marketers and consumers in that it has many strategic benefits in contributing to profitability of marketing activities and consumers' problem-solving activities. The main purpose of this study is 1) to explore the differences of perception between consumers and providers about nursing service quality. 2) to identify the useful tool between two tools measuring nursing service quality. To achieve these purposes of the study, the questionnaire was developed and distributed to 210 nurses who worked at seven subjected hospitals in Seoul. Also, 280 people who had a direct experience with the subjected hospital nursing services at the time of screening were involved. They were randomly selected at the seven subjected hospitals during August to September of 1998. Among them, 165 responses from nurses and 229 responses from others resulted in worthy finds. The measurement instrument for a nursing services quality evaluation was modified from the SERVQUAL model originated from Parasuraman, Zeithaml, and Berry (1988). The reliability coefficient of the scale was calculated and showed high degree of internal consistency (Cronbachs' Alpha = .9353). For data analysis, SPSS/PC was used for descriptive statistics, t-test, ANOVA and regression analysis. The results were as follows : 1) In the perception about nursing services quality, there were gap between consumers and providers. Especially the critical attributes in point of perception nursing services quality, naming satisfy, hygiene and performance factors, are very different contents. 2) In the comparison analysis of the usefulness tools it was turned out that SEVPERF model is more appropriate than SERVQUAL model. And in the analysis to identify the construct validity of the tool, it is turned out that the relationship between the constructing factors of the tool and the general satisfaction is significant.

Objectives: The aim of this study was to assess the quality of the information and characteristics associated with information packaging, and develop suggestions for how this web site might be improved. Methods: The 50 sites were selected for evaluation. Inclusion criteria for evaluation were the purpose and the popularity of the sites. Two kinds of evaluation tool were employed for the analysis: one that evaluate the quality of information and the design of the web sites, and another that evaluate the covered contents. A scoring system allowed the sites point on yes/no basis on the evaluation items. The association between quality of the web sites on sexuality education and their site characteristics were assessed using ANOVA. Conclusions: Major conclusions were as follows. First, the scope and currency of the selected web sites were found to be appropriate. Second, the authority of the information was found to be the most serious problem of the selected sites. Third, the category of sexual behavior found to be the most frequently mentioned and sexual health was the second. The least mentioned category was personal skills. Finally, sites operated by private organization were found to have more accurate information and better design feature than those operated by public organization and/or individual.
