Since most information is readily available these days, the shear volume of the information simply overwhelms people, rather than helping them as a form of useful knowledge. Thus, the quantity of information someone owns doesn't possess much significance. The possibility to well-utilize the quality information is much more important these days. Electronic culture map service is being provided these days to introduce various cultural information to people around the world. But its service is limited to 'visualization, collection, and integration of the data.' Which means, electronic culture maps are no more than a simple data collector. The main purpose of this thesis is to develop a new kind of knowledge/information service method which overcomes these shortcomings. To achieve this goal, at first, the thesis will take a close look at the characteristics and functions of Chosunjock culture maps, and then, it will clarify the definition of data, information, knowledge of cultural resources. And secondly, nd thirdly, the thesis will look up the Wayfinding contents, User Experience Design, User Context, and Organic design for knowledge/information service. And lastly, the thesis will develop the knowledge/information service, specifically based on Chosunjock cultural resources.

The purpose of this study is to evaluate the opinion survey data quality used in theses and to suggest the data quality evaluation model. We used 16 items which were suggested by KASR(Korean Association for Survey Research) as a standard of survey data quality evaluation in thesis. According to the result, the data quality used in the theses is very poor level not to be accepted. And we tried difference tests between two proportions in order to find there were significant differences among stochastical variables. The result showed that there were some significant differences in sampling error and number of analyzing method between doctor and master. we suggested a model that was weighted by 9 special items for a survey data quality evaluation in a thesis by observing them from KASR's principles.

The purpose of this thesis is to contribute to the activation of e-contract service for one stop e-trade by analyzing the problems and its solutions in e-contract service at home and abroad. In order to achieve the purpose of this thesis, case studies are done on e-contract service providers such as CECTRUST service of NTT DATA in Japan and HanCM.com of Haansoft in Korea and user companies such as Taisei Corporation using CECTRUST service and Hyundai Card using HanCM.com. The problems in the e-contract service are the lack of e-contract service providers, rare publicity of e-contract service, limited use of e-contract service at only home, higher pricing for e-contract service, short time management of e-contract documents by service providers, no application of newly developed security technology to e-contract service, unsatisfaction of requirements of e-contract service provider as trusted third party, absence of lower pricing e-contract service by service provider, authorizing key error in electronic signature under recognized authentication system in case of fail in renewal of digital certificate and reproduction of digital certificate. The solutions of these problems are the upbringing of e-contract service providers, broad publicity of e-contract service, development of e-contract service on a global basis, establishment of lower pricing for e-contract service, long time management of e-contract documents by service providers, application of newly developed security technology such as bio technology to e-contract service, satisfaction of requirements of e-contract service provider as trusted third party by designation of recognized e-document repository, development of lower e-contract service by way of application service provider(ASP), introduction of time stamping of e-contract document and signature key value. The limitation of this thesis is that the problems and its solutions could not meet with the broad recognition as they are conferred by intuition because of few e-contract service provider.

Objectives : First, to restore reliability of oriental prescriptions that are effective against incurable diseases, Second, in the short term, to secure the validity of traditional remedies with the help of accumulated data and in the long term, develop new therapeutic methods and prescriptions in order to broaden its aspect in the field of medicine. Third, to maintain predominance on oriental therapeutic methods and put it into practical use based upon the results obtained by this paper. Methods : In the primary sub-thesis(herbalogical analytic methods applied on unknown oriental prescriptions), models of analytic method and in gathering information that could be put into practice are being revised In the secondary sub-thesis(method in gathering and analysing in dealing with oriental prescription), several statistical approaches and analysis on data that has been gathered are being revised. In the tertiary sub-thesis(research on legal guarantee of the offerer rights), an alternative scheme that covers the limitations of the legislative content in dealing with offerer rights is being revised Results : This research has revealed several problems, including those which were foreseen, in proceeding with the project. The prospect of the involvement of the medical personnel engaging in the field of oriental medicine was remarkably bright. Given the condition that the project will proceed as it follows, unknown oriental prescriptions and remedies which have been particularly ignored will eventually play an important role in clinical practice. Conclusions : It is clear to everyone that these oriental remedies will remain ignored by the public unless they gain popularity. Strict verifications on these oriental remedies are definitely needed in order to overcome this limitation. Finally, it should provide a momentum in the field of medicine in gaining popularity to the public.

In order to produce the variety of UCC, the recommendation service is required which considers the copyright of UCC producer discriminated from one for UCC consumers and the purpose of its production. The recommender system designed in this thesis enables UCC which is much similar to one UCC producer utilizes to be used with custom-made when recommending and producing based on UCC view history and production list, etc. of its producer. The recommender system is largely divided into filtering based on the preferred tag, UCC filtering used when producing the preferred UCC and creating process of recommended UCC using the Pearson formula. The recommender system in this thesis requires the data which were used when producing UCC. For that, we added the reference factor so that the data of UCC which were utilized when producing UCC into the existing metadata can be recorded. If the recommender system suggested in this thesis is used, the more effective and convenient UCC recommendation services with custom-made for producers can be provided.

This thesis will study the determinants of consumer satisfaction based on the disconfirmation theory. The proposed questions are first, to find out if desire and expectation are conceptually distinct. Second, to study the effects of desire, expectation, perceived performance, desire congruency, and expectation congruency on clothing satisfaction. The data used in this thesis were obtained from a two stage longitudinal survey. SPSS WIN 8.0 was used for the analysis and the following method such as mean, correlation, t-test, hierarchical regression were applied. The results indicate that first, according to the correlation analysis and crosstab analysis, satisfaction and desire were perceived as two different concepts. Second, using the hierarchical regression analysis to compare the effects of determinants of consumer satisfaction, the model of desire, expectation, performance, desires congruency, expectations congruency best explain the clothing satisfaction. Among them, effects of performance had the strongest impact. Expectation did not influence satisfaction but desire did.

Lubrication has an important role to reduce frictional forces and temperature between cutting chips and the face of a tool. However, it has harmful effects to workers' health and working environment. The purpose of this thesis is to find cutting conditions through the quality analysis in boring for SM45C steel using MQL(Minimum Quantity Lubrication). Machining process is super drill, tip drill, end mill and boring in order. Experimental factors of boring and the quantity of mist air are properly selected. With the analysis of experimental data, this thesis shows that boring with MQL improves the surface roughness when spindle speed is 934rpm or feeding speed is 74mm/min.
