The emergence of the Internet shopping agent enabled consumers to enjoy Internet shopping more easily and quickly. Especially, the role of Internet shopping agent is becoming more important following the information overload trend on the Internet in that the consumers can promptly obtain information about a certain product and its price among countless items on the Internet. As a result, consumers can now enjoy shopping more easily, compared to the offline shopping which requires a lot of efforts in comparing the products and purchasing them. Since the Internet shopping agents collect extensive information about the products' price, delivery period, detailed characteristics, etc., and present a comparison table containing the information to the consumers, the consumers can shop more quickly at lower price using such shopping agents. However, it has not been sufficiently studied about how the various functions of shopping agents actually support consumers' purchase decision making procedure in everyday life, and if they do, in which stages they play a supporting role in consumers' purchase decision making system. Therefore, this study conducts an empirical analysis on the role of the Internet shopping agents in the purchase decision making process of the consumers, considering the Internet shopping agent as a decision making supporting system. Moreover, it analyzes how the effects of the Internet shopping agent differs according to the consumers' knowledge level about the products.

의사결정에 있어 정보란 의사결정자가 의사결정을 하는데 사용하도록 의미 있고 유용한 형태로 처리된 데이터이다. 이러한 정보들에 있어서 불필요한 속성들을 제거하여 처리함으로써 의사결정의 효율을 높일 수 있다. 러프 집합 이론은 불필요한 속성을 제거하고 분류화 하는데 뛰어난 능력을 가지고 있으나 속성 감축시 속성 수와 튜플 수에 따라 복잡한 계산을 요구한다. 따라서 속성들 사이의 상호연관성을 나타내는 척도로서, 두 변수간의 독립성에 관한 검정방법인 $\chi$2와 러프 집합의 종속성을 이용하여 속성들을 감축하고 이를 신경망의 입력 유니트로 사용하므로써 기존의 모든 속성을 입력으로 하여 신경망을 구성하는 것보다 간단하며 학습효율의 향상 및 정확한 의사결정을 지원할 수 있다.

The purpose of this study is to understand and verify the incentives as an important market environment and to help consumers use them effectively, and consequently to improve the consumer welfare. This study examined the representative incentive, the sales promotions which can effect on the consumer decision making process and current issues of them. For the purpose, a coffee specialty store was hypothesized and the subjects were 20∼30 years old, since the sales promotions can be more effective toward the younger consumers making their decisions low-involvement goods and services. The conclusions can be summarized as follows; Consumers understand the advantages and disadvantages of sales promotion very well, and use them rationally and usefully to maximize their satisfaction. the sales promotions act as incentives in the all steps of decision making processes. Generally, consumers prefer to get things at a good price, so in this survey, the discount coupons and the point accumulative membership had more effect than others. Consumers pointed out controversial issues of the sales promotions as follows: the sales promotions could bring about cost rising and unnecessary and/or impulse buying, and stir up speculative motivation. These are common serious problems in the sales promotions. The sales promotions are very useful tools in promoting sales but not fundamental in the long run. Marketers and manufacturers should keep it in mind that the best way to satisfy the consumers is to keep all things in good quality and moderate price.

This dissertation are studying the conceptual structure of decision making situation in libraries, by analyzing the library function, decision makings of library and then seeking economic and efficient alternative decision making by programming the· decision making situations, and finally, introducing how to apply management information system or decision making support system. For this purpose, in order to analyzing necessary factors for the decision making system, the questionnaire used Lickert method were distributed to 400 librarians of 36 universities in Seoul by means of mail. 193 librarians, $48\%$ of the questionnaire, are returned are studied by using 'SYSTAT' statistical software to figure out the factors of the decision making system. This dissertation was put six hypotheses and tested with the returned questionnaire. The following five result can be asserted. First, to the higher degree of the librarians' participation in the important library decision makings, the quality of formal library services are improved regardless of seniority of the work. Secondly, the t-test results show that all of t-test scores of seniority of the work, educational background, and responsibilities of the work are exceeding significant level and perception of decision making was proved to be different depending on seniority of the work, educational background, and responsibilities of the work in libraries. Thirdly, as the results of factor af factor analysis, the encouragement on participation in the library academic activities, the extent to get useful information about performances of library and the improvements of library works were grouped by similar posibilities of distribution and therfore the academic activities, the collection of information and the improvement of library performances is proved to be interrelational each other. Fourthly, the fifth hypothesis of the close relationship between the decision making situation and types of advisor by it was more or less interrelational, but their relationship was not seen some significancies. Lastly, as the dynamic organization of library management forming a special commitee or a project team with librarian can improve the extent and quality of the librarian's participation in the decision making of library works, and thus library will become to performance more rational and effective library management.

This study is designed to review the methods of duplicate copies decision making in the academic library. In this thesis, I surveyed queueing & markov model, statistical model, and simulation model. The contents of the study can be summarized as follows: 1) Queueing and markov model is used for one of duplicate copies decision-making methods. This model was suggested by Leimkuler, Morse, and Chen, etc. Leimkuler proposed growth model, storage model, and availability model through using system analysis method. Queueing theory is a n.0, pplied to Leimkuler's availability model. Morse ad Chen a n.0, pplied queueing and markov model to their theory. They used queueing theory for measuring satisfaction level and Markov model for predicting user demand. 2) Another model of duplicate copies decision-making methods is statistical model. This model is suggested by Grant and Sohn, Jung Pyo. Grant suggested a model with a formula to satisfy the user demand more than 95%, Sohn, Jung Pyo suggested a model with two formulars: one for duplicate copies decision-making by using standard deviation and the other for duplicate copies predicting by using coefficient of variation. 3) Simulation model is used for one of duplicate copies decision-making methods. This model is suggested by Buckland and Arms. Buckland considered both loan period and duplicate copies simultaneously in his simulation model. Arms suggested computer-simulation model as one of duplicate copies decision-making methods. These methods can help improve the efficiency of collection development and solve some problems (space, staff, budget, etc, ) of Korean academic libraries today.
