  • 오늘날 정보화 사회에서 경쟁하는 기업들에 있어서 데이터품질 저하는 기업경쟁력 하락과 새로운 비용창출이라는 부정적인 영향요인으로써 작용하고 있다. 이러한 데이터품질 저하의 문제를 해결하기 위해 데이터품질에 대한 많은 선행연구들이 진행되어 왔으며, 데이터품질의 측면 중 결과적 이고 현상적인 품질개념인 데이터 값의 품질과 데이터서비스의 품질에 대해 주로 연구되어 왔다. 이에 반해 본 연구에서는 원인적인 데이터품질 개념인 데이터의 구조적 품질을 메타데이터 관리의 관점에서 연구하였으며, 이를 통해 평가와 개선을 위한 관리의 관점이 적용된 데이터품질관리 성숙도모델을 제시하였다. 또한 본 연구에서 제시한 데이터품질관리 성숙도모델의 타당성 검증을 위해 데이터품질 관리단계가 성숙될수록 데이터품질수준이 높아지게 된다는 것을 실증적으로 검증하였다.

  • The purpose of this research is to study the effect of service qualify improvement strategy and its practices on firms' competitive advantage, and identify their influence on customer satisfaction and loyalty. According to this purpose. this paper hypothesized that high service qualify will satisfy customers' needs and result in improved customers' loyalty. Thus, empirical study was conducted to identify the relationships among factors which were identified through literature review. Data were collected from the customers of 3 luxurious japanese restaurants in Seoul. The result of data analyses shows (1) Serve quality factors such as customer service, qualify of meal, location and facility, and types of restaurants make significant difference among three restaurants in terms of customers' perception about service quality; (2) There is statistically significant difference among three restaurants in terms of customers' satisfaction, but there is no significant difference among them in terms of customers' loyalty; and (3) Not only the result from analysis on japanese restaurants inside hotels but also that on the independent japanese restaurant in Kangnam area, shows that service quality factors have significant effect on both customers' satisfaction and loyalty.

  • Purpose: This study was to identify the relations of rural elderly people' self-esteem and social support to their qualify of life. Methods: Data were collected from 228 rural elderly. The instruments used in this study were the self-esteem scale developed by Rogenberg(1965), the MOS-SSS(1991) and the qualify of life scale by Choi(1986). Data were analyzed by SPSS 12.0 using t-test. ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: Self-esteem and social support were in a positive correlation with each other(r=.467, p=.000). Social support and quality of life were in a positive correlation with each other(r=.512, p=.000). Self-esteem and quality of life were in a positive correlation with each other(r=.555, p=.000). The significant predictors of quality of life were self esteem, social support, and economic status, and the three factors accounted for 42.5% of variances in rural elderly people's quality of life. Conclusion: These results suggest that self-esteem, social support, economic status can be important factors for the qualify of life in the rural elderly. It proposes the basis for program development to improve rural elderly people's qualify of life.

  • Mathematical basis of interpretation of data from nondestructive evaluation (NDE) methods in bridge inspection is presented. In bridge inspection with NDE methods, NDE data are not assessments. NDE data must be interpreted as condition of element. Interpretation is then assessment. Correct assessments of conditions of bridge elements depend on the accuracy and variability in test data as well as on the uncertainty of correlations between attributes (what is measured) and conditions (what is sought in the inspection). Inaccuracy and variability in test data defines the qualify or NDE test. The qualify or test itself is important, but in view of condition assessment, the significance of uncertainty in correlations of attributes and conditions must be combined. NDE methods that are accurate in their measurements may still be found to be poor methods if attributes are uncertain indicators of condition of bridge elements. This paper reports mathematical presentation of inaccuracy and variability in test data and of uncertainty in correlation of attributes to element conditions with three examples of NDE methods.

  • 기업에서 관리하여야 하는 데이터의 양이 급속히 증대함에 따라 데이터의 품질관리 문제가 대두되고 있다. 또한 데이터의 통합이 이루어지지 않아 중복관리, 저품질의 정보제공, 특정 데이터의 누락 등의 문제가 발생하고 있어 본 연구에서는 메타데이터를 활용한 데이터 품질관리 방안을 모색한다. 이를 위해 메타데이터의 의의 및 다양한 메타데이터 관리 현황을 분석하고, 실무자와의 인터뷰를 통해 컨테이너터미널을 대상으로 메타데이터 관리 방안을 제시하였다. 주요 연구 내용은 A사의 메타데이터 관리를 위해 데이터 표준화 과정을 수행하였으며, 제약 조건 및 조정 사항 등을 메타데이터 레파지토리에 반영하였다. 본 연구의 공헌도는 제시된 관리 방안을 통해 A사의 데이터 품질 문제를 개선할 수 있다는 것과 해당 도메인을 대상으로 메타데이터 관리 방안을 적용하였다는데 있다. 본 연구의 한계점은 관리 방안이 일부분의 업무에만 적용되었다는 점이며, 향후 기업과 기업간의 통합을 위한 메타데이터 관리 방안에 대한 연구가 필요하다.

  • The Data quality management system(DQMS) organizes and helps manage and process time sequence data usually collected in monitoring networks and programs. DQMS places particular emphasis on data qualify while maintaining a highly organized and convenient structure for data. It operates with in a flexible and powerful commercial relational data base environment which can readily link to other software platforms from local spreadsheets to network server. The Korea Institute of Energy Research(KIER) has been solar radiation data since May, 1991 for 16 different locations. KIER's new data is expected to be extensively used by designer and researchers of solar systems in lieu of unreliable old ones. Unfortunately, the quality of the data has not always been properly mentioned. The purpose of this study is to systematically identify errors in such data set using DQMS in an effort to rehabilitate error-ridden old data. DET successfully uncovered solar radiation data that had questionable quality.

  • This study was designed towards female college students to find out how increasing promotional marketing means are affecting the evaluation of clothing products; qualify perception, value perception, and purchase intention. 704 female college students participated in this study and SPSS package was used to analyze gathered data. The results of this study were as follows: First, the use of sales promotional means and preference had a significant difference among students demographic factors(residence, whole Income of the family, allowance, and clothing expenses). Second, qualify perception, value perception, and purchasing intention were the three factors of clothing product evaluation. Third, normal price and $30\%$ sale price clothing was perceived as high quality product and $50\%$ sale price clothing was perceived as high valued product. Purchasing intention was high when low price was suggested or promotional gift was given. Fourth, when considering product price as the factor of product evaluation, there were significant difference between the prices of product. And also, considering the product price, there were significant difference among factors of product evaluation and sales promotional means. Fifth, there was significant correlation between qualify perception, value perception, purchasing intention, usage and preference of promotional means. Further more, value perception was main factor that affected purchasing intention.

  • This study deals with the laser cutting of stencil for the PCB. The most important aim of this study is to determine optimal conditions which make good-qualify stencil in Nd:YAG laser cutting. We made an experiment according to various variables (power. type of mask. gas pressure, cutting speed, and pulse width) and analyzed the cutting characteristics (surface roughness, kerf width. dross) . Each variable has optimal value for good-qualify cut edge under fixed condition. And neural network after learning experimental data with a million time iteration could predict surface roughness of cut edge under arbitrary condition approximately.
