A Study On Comparison of Excellence between SERVQUAL and SERVPERV AL Scale
Cho, Yoon-Shik ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 1~10
The purpose of this research is to compare whether SERVQUAL or SERVPERV AL scale is more excellent when explaining customer satisfaction and repurchase intention. The value of R2 which shows explaining power is used to test the excellence of the scale. As a result of comparison and analysis, SERVPERV AL scale showed better explaining power of customer satisfaction and repurchase intention than SERVQUAL. This result is because SERVPERV AL scale predicates overall estimation on utility of product/service.
Mobile Computing Algorithm on IEEE 802.11b for Ubiquitous Computing
Kim, Wu-Woan ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 11~24
In this paper, the patterns of movement used in the mobile communication systems are adopted in the mobile computing environment to reduce handover delay and to support seamless handover for MIPv6 based on IEEE 802.11 networks. That is, RtSolPr message and PrRtAdv message can be treated before handover. As the result, it is possible to assign NCoA to MN and Next Access Router(NAR) before handover starts. This can minimize handover delay and reduce the total handover delay.
Data-Adaptive ECOC for Multicategory Classification
Seok, Kyung-Ha ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 25~36
Error Correcting Output Codes (ECOC) can improve generalization performance when applied to multicategory classification problem. In this study we propose a new criterion to select hyperparameters included in ECOC scheme. Instead of margins of a data we propose to use the probability of misclassification error since it makes the criterion simple. Using this we obtain an upper bound of leave-one-out error of OVA(one vs all) method. Our experiments from real and synthetic data indicate that the bound leads to good estimates of parameters.
A Study on Survey Questionnaire to Measure the Knowledge Level of the Foodborne Disease
Bae, Wha-Soo ; Kim, Jung-In ; Choi, Kook-Lyeol ; Kim, Byung-Soo ; Cho, Young-Joon ; Oh, Dong-Kwan ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 37~51
In this article, the aim is at evaluating the knowledge level of the foodbome disease by developing a reasonable survey questionnaire model. Each questions of the questionnaire is made up to check the knowledge covering the several fields of materials related to the foodbome disease. The pilot survey is implemented to evaluate the validity of questionnaire. Each question in questionnaire is scored to get the quantitative measure of the foodbome disease knowledge by converting the total score into 100 points.
A Study on the Causes of Stagnancy in Six Sigma Implementation
Ahn, Byoung-Jin ; Kim, Sang-Ik ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 53~69
Six Sigma is a proven management philosophy that can be employed to improve productivity dramatically in various fields of industries. However some companies where Six Sigma is adopted confront stagnancy due to many kinds of causes of impediment. In this paper, the causes of stagnancy in the diverse stages of Six Sigma implementation are studied. Moreover in this paper results of such causes are also discussed.
A Study on the Satisfaction Level of Local Government Public Service
Ko, Je-Suk ;
Journal of the Korean Data and Information Science Society, volume 19, issue 1, 2008, Pages 71~83
Assessing local government performance has become a crucial issue in recent years. This paper addresses the satisfaction level of local government public service, which is defined as a degree of the results or the impacts of the local government public service delivery on the citizen's needs, demands and expectations. The satisfaction level of local government public service can improve decisions made by local government managers, and enhance accountability of local government to the citizens they serve. This study focuses especially on the various aspects of administrative systems in a local government and developed a systematic survey for their performance. Explanations for the evaluation items and the analysis of survey are discussed throughout the paper.
