This study proposes a new answering mechanism of deciding whether to purchase or not under uncertainty-real risk answering mechanism (R-RAM) for real transaction and hypothetical risk answering mechanism (H-RAM). It IS also. shown that the traditional answering mechanism (TAM) assumed in most of existing contingent valuation methods should be applied in a real transaction without uncertainty. While the willingness to pay (WTP) being simply compared with the bidding price m TAM, the mean of WTP should be greater than the bidding pnce at least by the risk premium for a purchase decision m R-RAM and H-RAM. Only difference between R-RAM and H-RAM is risk premium. The H-RAM takes a smaller risk premium than the R-RAM. This study proposes the contingent valuation method (CVM) with H-RAM could be an alternative to reducing the under-or over-estimation of WTP by comparing the WTP estimates obtained from three different CVMs with TAM, R-RAM and H-RAM.

In a buyer-seller transaction process, 'value for money,' a measure of quality-price-ratio, is one of the most important criteria for buyers' purchasing decisions. The purpose of this paper is to suggest a method which helps online shoppers choose the best of several sellers offering homogeneous goods. We suggest FDH (free disposal hull) model, an applied model of data envelopment analysis (DEA), for online buyer-seller transactions and verify it with the data from an Internet comparison shopping site. For this purpose, we analyze consumer choice behaviors by examining how consumers respond to different sale conditions such as price, brand, or delivery time. Then, we implement a seller recommendation system to support buyers' purchasing decisions. We expect our FDH model to provide valuable information for rational buyers who want to pay the least price for high quality products/services and to be used in implementing automated evaluation processes in micro transactions. Moreover, we expect that our results can be utilized for sellers' benchmarking strategies which help sellers be more competitive by showing them how to attract buyers.

구매 의사 결정 과정에서 구매자는 상품 정보와 가격 정보를 필요로 한다. 웹상의 판매자 위주의 시장으로부터 필요한 정보를 수집하려면, 구매자는 매번 구매 때마다 판매자의 사이트를 검색해야 한다. 심지어 구매자가 거래하고 있는 판매자로부터 과거에 구매한 경험이 있는 아이템을 구매하는 경우에도 마찬가지이다. 현재의 전자상거래 환경에서는, 이렇게 기억을 활용하지 않고(memory-less) 검색에만 의존하는 구매자의 행태가 일반적이다. 이 현상을 조직의 구매 경험이 구성원들에게 공유되어야 하는 기업 구매자의 경우에 있어서는 대단히 낭비적인 요소로 작용될 것이다. 구매자 에이전트에게 기억 능력을 부여하려면, 구매자 에이전트와 판매자 에이전트가 갖고 있는 정보간의 일관성을 유지해 주어야 할 필요가 있다. 최소의 노력으로 일관성을 유지하려면, 구매자 에이전트와 판매자 에이전트간에 체계적인 갱신 프로토콜이 필요하다. 본 연구에서는 6가지의 프로토콜(Instantaneous Pull, Periodic Pull, Instantaneous Push, Periodic Push, Instantaneous Solicited Push, Periodic Solicited Push)을 비교하고, 에이전트의 아키텍처와 KQML/XML에 기반 한 메시지 구조를 제시한다. 이들 프로토콜의 상황에 따른 수행 성능 평가가 진행 중이며, 이러한 상황에 적응할 수 있는 에이전트의 프로토타입이 현재 개발 중이다.

웹이라는 환경은 다양한 정보원천을 생성해냈고, 온라인 소비자는 시간과 노력의 비용을 줄여 보다 합리적인 의사결정을 하기 위하여 웹 정보탐색을 한다. 특히 인터넷 환경은 정보를 획득하는 비용을 낮춤으로써 유용한 정보원천의 역할을 수행하고 있다(Bakos, 1997; Bar-Ilan, 2001). 그러나 너무 많은 정보는 오히려 소비자들의 의사결정을 방해할 수 있는데, 이때 소비자들은 정보원천에 대한 인지경향, 즉 신념수준을 가지고 자신에게 필요한 정보를 취사선택하게 된다(Schuman and Johnson, 1976). 이러한 관점에서 온라인상에서의 구매의사결정과 관련해서 주요하게 참조되는 정보원천을 파악하는 것은 의미있는 일이라 할 수 있다. 이에 본 연구에서는 사전조사를 통해 온라인 주요 정보원천으로 온라인 구매경험, 온라인 구전정보, 판매자 정보를 도출하였다. 그리고 이러한 정보원천이 제품만족, 정보만족에 미치는 영향관계를 알아보고, 이어서 정보만족과 제품만족이 인터넷 쇼핑몰에 대한 소비자의 전반적인 만족에 미치는 영향을 살펴보았다. 분석결과, 온라인 정보원천의 모든 변수들이 정보만족에 유의한 영향관계를 갖는 것으로 나타났으며, 제품만족과의 관계에서는 판매자 제공정보가 유의하지 않게 나타났다. 또한 정보만족과 제품만족 모두 소비자의 전반적인 만족에 유의한 영향을 미치는 것으로 나타났다. 이와 같은 결과는 온라인상에서의 정보의 중요성을 입증하는 것으로, 온라인 소비자의 정보원천에 대한 이용과 평가를 이해하는데 새로운 시각을 제공해주고, 정보원천에 대한 관리와 활용에 관한 실무적 시사점을 제시해 줄 것으로 기대된다.

This study investigated the consumption status, focusing on the factors related to book loans and purchases of reading consumers. Library experience, reading purpose, book genre, book price, and new books are the decision-making factors regarding consumers' book loans and purchases. As a result of a survey of reading consumers focusing on these factors, the more experience they have in using the library, the more they consume books. As for the book genre, the higher the loan consumption, the higher the purchase consumption. Consumers for reading purposes for liberal arts, hobbies, and leisure activities showed higher loan and purchase consumption than consumers for reading purposes for information acquisition, learning, and research. In terms of book price (cost), loan consumption was higher than purchase consumption. In the case of new books, both loan and purchase consumption were high. In general, reading consumers considered book loan consumption first when it was a library-owned book, and cases that led to book purchase consumption in the book market were confirmed. Based on this, it was proposed that win-win cooperation between the library and the book industry could be achieved.

The information processing capabilities of contemporary people have reached its limit as the daily life in an information society calls for prompt judgment and decisions while being overwhelmed with information. We no longer make optimal decisions after analyzing all necessary data and information and instead make automatic decisions based on just a handful of important information. Such a phenomenon can be observed not just in daily life but also on the internet. People believe they are making a rational choice when selecting and purchasing a product online, but in fact subconscious thoughts and behavior triggered immediately by certain parts of the brain without our knowing are what makes the decision. Therefore, this study seeks to investigate the cases of various UX designs where the persuasion method based on Cialdini's psychology of persuasion is applied and to suggest a direction for a more effective user interface design based on the findings.

단일 기업의 내부적인 공급 사슬 환경이 아닌 정보의 공유가 없는 일정한 수의 생산자들과 수요자들로 이루어진 경쟁적인 공급 사슬환경에서는 각각의 생산자와 수요자들은 상대방의 가격에 대한 정보만을 가지고 의사결정을 하는 것이 일반적이다. 이러한 공급 사슬 환경에서 자신의 이익을 최대화시키며, 경쟁적인 상대방과의 협상을 효율적으로 하기 위해서는 자신의 시스템에 대한 정확한 수리적인 모델이 필요하다. 수요자의 경우, 시장 판매 가격은 제품의 구매 원가와 관련이 있으며 제품의 구매원가는 제품의 수요에 커다란 영향을 미친다. 이러한 제품 수요의 변화는 수요자가 생산자에게 요구하는 경제적인 주문량과 밀접한 관련성을 지닌다. 또한 생산자의 경우, 생산 공정의 변화가 생산 원가에 영향을 미치기 때문에 수요자가 주문하는 경제적인 주문량의 변화에 따른 정확한 생산 원가의 산출이 필요하다. 본 논문에서는 생산자와 수요자의 측면에서 각각의 이익을 최대화할 수 있는 수리적인 모델을 제시한다. 수요자 측면에서는 경쟁 시장환경 기반의 수요량과 시장 가격을 바탕으로 한 최적의 주문량 및 가격을 결정하는 모델을 제시하고, 생산자 측면에서는 수요자의 주문량을 만족시켜주기 위해 생산시스템의 성능 요소를 반영산 생산 원가 산출 모델을 이용하여 납기일 내데 수요자의 주문량을 만족시키기 위한 최적 생산 원가를 산출하는 모델을 제시한다. 제시한 두 가지 모델을 이용하여 생산자와 수요자는 제품에 대한 가격 협상을 통해 각각의 이익을 증진시킬 수 있는 의사결절이 가능하다.

Publication Industry of scientific technology is showing tendency of decreasing in sales, which clearly draws down curve since 2000. The printing culture is declining whether it is because of trend avoiding pure science or technological science and engineering, advancement of mass media or increasing frequency of using internet. Nevertheless, researcher considered car industry in publication industry as a life-long purpose for study. For this reason, the researcher tried to find the variables of the marketing which give impact on the customers such as student group and consumer who buys cars, when buying professional books. The found variables are expected to have a huge impact on the publication industry of professional books. As a result of research, in the area of the vision and motive, most said that they have "chosen a major in car because they liked car in usual base." In the stage of recognizing the problem, they buy the books when it is inevitably necessary. In the stage of searching for the information, they get information from advertisements, friends, professors, internet or sales clerk in book stores. In the stage of evaluation, they look for the title and the publication date of the books. In addition, in the stage of deciding purchase, "buy immediately" was the most frequent answer while impulsive purchase is the least frequent answer. In the stage of evaluating after purchase, many of them mostly are satisfied with their purchase.

Supplier relationship management (SRM) is an important contributor to a company's efficiency and credibility. Although several ways are used to provide SRM functionality, these are often not easily integrated with existing procurement systems. We designed and implemented a practical SRM system called BestChoice SRM and present its design and architecture. It has the core functionality of SRM with the simple adaptability of BestChoice which is a decision support system for evaluating suppliers with the aid of visualized analysis It allows seamless integration with existing systems and permits flexible strategy changes as market conditions shift. The key to this flexibility is template-based segmentation. Ease of integration was demonstrated through the installation of BestChoice SRM at a major Korean commercial e-procurement agency.

Consumers of web novels read online reviews in order to decrease uncertainty when purchasing a web novel. This study examines the types of messages (factual or evaluative) that consumers find more useful and verifies the moderating effect of individual analytical decision-making style levels on differences in usefulness evaluation. Based on the tendency to acquire objective information, the usefulness of factual online reviews was expected to be higher in the context of buying experience goods, such as a web novel. Levels of analytical decision-making styles, which were classified based on individual perception, are also expected to affect the usefulness evaluation of reviews. Experiments 1 and 2 were repeatedly conducted to examine whether consumers think factual reviews are more useful than evaluative reviews. In particular, Experiment 2 was conducted to simulate the circumstance of selecting a romance web novel and demonstrated that reviews have a significant effect on messages and decision-making styles. The interaction effect between analytical decision-making style levels and review message types was also confirmed in Experiment 2. The results of this study can help researchers and marketers comprehend the behavioral patterns of web novel readers when evaluating reviews and consuming experience goods.
