This study is to empirically analyze the effects on job performance of Accounting Information Systems, Analysis methods were used to Cronbach's Alpha analysis, Factor analysis, analysis of variance(ANOVA) and regression in odor by the contingency grouping method. The results of this study are as follows : First, The regression analysis had effects on AIS utility and job performance. Second, The Analysis of variance(ANOVA) had non-effects on systems operating degree and systems satisfaction. Third, The input variables of information accuracy and systems satisfaction had additional effect about IT capability.

The purpose of this study is to investigate whether Google Scholar (GS) can substitute Web of Science (WoS) for those who don't have access to the subscription-based indexing service and if users feel GS is useful for scholarly information. To achieve the research purpose, the study evaluates both quantitative and qualitative aspects of the two databases. The major results through statistical analysis show that GS indexes much more records and citations for LIS journals than WoS(p < .01), but users' feedback about GS is not better than those about WoS.

The purpose of this study intends to evaluate the usefulness of the automated cataloging systems. For the purpose. this study investigated theoretical methods for the quality criteria and developed 4 evaluation criteria. Also developed were indicators to measure the value of each criteria And the catalogers of academic libraries using three major LAS were carefully chosen to conduct the usefulness tests. The proposed model was verified reliability and validity. This study is suggested guidelines to evaluate and improve the automated cataloging systems.

본 논문에서는 유비쿼터스 환경에서 인간의 행동패턴을 인식하고 이 결과를 활용하여 사용자의 의도를 추론하는 방법론에 관해 기술한다. 인간행동의 예측에 관한 지식표현으로부터의 추론기능과 예제패턴 기반의 학습기능을 동시에 지원하는 모델을 제시하고 이론의 타당성과 유용성을 고찰한다. 의도 추론 문제에서 지식기반 기법이 갖는 불완전성을 극복하기 위하여 예제기반 학습능력의 필요성을 도출하는 한편, 다양한 변이가 존재하는 응용에서 학습데이터 선정의 어려움을 보완하기 위한 방법론을 제시한다. 세부적으로 인간행동에 관한 특징표현과 행동패턴 클래스를 정의하고 이들간의 관계를 고유한 지식표현 규칙으로 정형화 한다. 또한 제안된 지식표현을 수용하는 추론 메커니즘을 제시하며, 제시한 모델의 부수적 특징으로 학습과정을 통한 지식 정련기능의 유용성을 고찰한다.

This study set out to analyze the impacts of convergence products(cell phones, PDAs, IPTV, and portable game consoles) on the consumers' purchase intention and satisfaction. These results of the research model show that usefulness, perceived risk, and communication had significant influences on purchase intention, and usefulness, innovation, perceived risk, and communication on satisfaction. But there were differences according to the product kinds. The results indicate that usefulness, convenience, perceived risk, and communication are the major factors affecting the satisfaction and purchase intention of convergence products and that innovation didn't have much influence on them. And there were small differences among the influential factors according to the kinds of convergence products.

The internet has the capabilities of supporting and facilitating several forms of consumer interaction including one-to-one, one to many, or many-to-many interactions. Especially, previous studies revealed that the Online Word-of-Mouth communication is widely used as a source of customer's information seeking and purchase decision making. Even with this importance of the Online Word-of-Mouth communication on internet, few research has systematically addressed the issue. This study investigates the effect of interpersonal communication on consumers' information search activities and develops a model that depicts the key antecedents and mediating variables of interpersonal communication in internet shopping environment. The results are as follows: First, choice uncertainty, perceived risk, and knowledge uncertainty play an important role for perceived usefulness. Second, perceived usefulness has directly affected interactive communication of consumers' communication style. Thus, it is essential for internet companies to find ways to encourage their customers to engage in word-of-mouth communication.

A study herein is carried out for acceptance procedure of innovative products in the aspect which usage intention is formed by usefulness expectation and rejection factors for innovative products during acceptance procedure of users when information technology innovative products are launched in the market. Empirical study was carried out for non-smart phone users within mobile phone users. As a result of study, firstly, usefulness expectation of users for information technology innovative products is positively (+) affecting to usage intention, while usefulness expectation was shown to be negatively (-) affecting to rejection. Secondly, social factors were found which positively (+) affect to usefulness expectation for innovative products, and satisfaction for conventional products negatively (-) affects to usefulness expectation. Thirdly, there were satisfaction and consuming effort for conventional products from consumers for the factors which affects to innovative products rejection of consumers. Based on the result of study herein, there is a specific strategy needed for information technology innovative products although consumers have expectation usefulness for the products as well as rejection which brings out to remove the intention to use the products.

The purpose of this study is to search information attributes suitable for SNS and to identify the influence of individuals or groups who contribute to the creation and diffusion of information in the SNS. The researchers extracted the accuracy, two-sided information, novelty, diversity, and experiential factors that influence the acceptance and diffusion of information in the SNS, and identified the relationships among the variables, the usefulness of information and the degree of information diffusion intention. And researchers studied market maven who play the key role in creating and diffusing SNS information. A total of 600 questionnaires were collected and 549 questionnaires were used to test the research hypothesis. The results of the study are as follows. Consumers considered information, which had accuracy, two-sided, and experiential attributes, as useful. But novelty or diversity information were regarded as unuseful because of motive to avoid ambiguity. In the Market Maven Group who have the ability to acquire and edit SNS information, however, there were weak or negative causality between experience and accuracy and information usability factors. but positive causality between novelty and diversity factors of information and usability.
