This study surveyed purchase behavior of users who purchased goods within the last year to analyze the relationship of search intention to purchase behavior according to SNS channel attributes. Based on these findings, it is analyzed that the information provision and interrelationships in SNS channel attributes affect search intent. In order to enhance the purchase behavior through the users of NS Channel, reliability and information availability are also cited as major issues, but more importantly, SNS channel search index is more important. It is also important to increase search indexes by simply increasing the attributes of SNS channels by improving the reliability of information and information availability, and by enhancing information delivery performance and interaction.

Current electronic voting systems are not sufficient to satisfy trustworthy elections as they do not provide any proof or confirming evidence of their honesty. This lack of trustworthiness is the main reason why e-voting is not widespread even though e-voting is expected to be more efficient than the current plain paper voting. Many experts believe that the only way to assure voters that their intended votes are casted is to use paper receipts. In this paper, we propose an efficient scheme for issuing receipts to voters in an e-voting environment using the well-known cut-and-choose method. Our scheme does not require any special printers or scanners, nor frequent observations of voting machines. In addition, our scheme is more secure than the previous schemes.

The purpose of this study is to focus on developing the performance indicators for the distribution of scholarly information based on BSC and to analyze the importance of the performance indicators against the specialists. From the case studies on performance indicators both at home and abroad four viewpoints(information resource, information service, user, and economy) were derived. In addition. the core success factors(CSF) and key performance indicators(KPI) were extracted from the viewpoints. Four viewpoints are composed of 12 CSF items and 31 KPI items. In order to analyze the weight of the performance indicators. questions were thrown to the specialists in universities and research institutes. For the method of analysis, analytic hierarchy process(AHP) was adopted. As a result, the analysis showed that the user viewpoint, information service viewpoint, information resource viewpoint and economic viewpoint are in the order of their importance.

Cryptographic applications, such as data confidentiality and authentication, must be used for secure data communications. PRNG(Pseudo-Random Number Generator) is a basic cryptographic component which is supposed to be satisfied by criteria that we provable security and randomness properties. PRNG it used for generating an initial value or key value of cipher and security of whole cryptographic module depends on the security of PRNG. In this paper, we introduce an PRNG based on a block cipher and prove their security.

Although an insurance criterion for reliance is unified, the difference in evaluation mechanism in every country is already ambiguity. In other words, the aspect of objectivity would be a little because it is true that the vulnerability evaluation include evaluator, scenario and tools (TSVES) applying in test, depth and scope of evaluation. But evaluation results can be difference in accordance with each evaluation elements. By using TSVES to evaluating network security vulnerability, first, we expected the evaluation results is impartiality, objectivity, repeatability, reproducibility, appropriateness and soundness of results. Second, it could be transferred manual ways into automation ways, and then expected easiness and safety of extension and modification in a quality of products as well as a dramatical reduction of waste of time and energy.

This study is to analyze the effect of compatibility of information characteristics and information technology structure on AIS performance. This used financial and non-financial factors as the characteristics of management accounting information and used information technology structure as centralization and decentralization classified by Ahtuv et.(1989) and Fiedler et.(1996). 425 sampling companies are selected randomly and 137 of them were used in this study. The results of this study are as follows. First, In compatibility analysis between the characteristics of management accounting information and information technology structure, in case of companies which have centralized data process system, AIS performance of companies which use financial information is higher than that of companies which use non-financial information. However, no meaningful results show statistically. in case of companies which have decentralized data process system, AIS performance of companies which use non-financial information is higher than that of companies which use financial information. Also the statistical results show the meaning at the p. < 0.01.

The purpose of this study is to investigate the impact of leader-member exchange(LMX) on employees' creativity, and task performance focusing on the mediating effect of information sharing and job involvement. Based on the review of related references, we suggested our research model and hypothesis and then tested empirically. From these analyses, we can find some significant findings. First, LMX has a positive impact on information sharing. Second, information sharing has a positive impact on job involvement, creativity, and task performance. Third, information sharing has significant mediating effects on the relationship between LMX and job involvement, creativity, and task performance. Fourth, job involvement also has significant mediating effects on the relationship between information sharing and creativity and task performance. These results showed that information sharing and job involvement played their role as a meaningful mediator.

For the education information system, evaluation of the performance have to incorporate the special characteristics od education. This paper is to develop some measures to assess the performance of Korean National Education Information System (NEIS). Performance measures are classified those into three detailed areas as the flow of value chain. which include end-users area, education process area and performance area. Research results show that the users's concern to the information system have an affirmative influence on the satisfaction of users, and attitude change of users have also a positive influence on the administration area of the information system such as task productivity, task innovation, satisfaction of the education users, activity of control process. Also, user's satisfaction for NEIS, that comes from the communication, have an affirmative influence on the better performance of education,

This study aims to demonstrate the importance of information literacy instructions by showing effects of information literacy skills on critical thinking dispositions among high school students. We collected 761 survey responses from high school students and conducted multiple regression analysis to examine the relationships between the two variables. The findings show that (1) students' information search skills affect their pursuit of truth, openness, inquiring mind, and objectivity, (2) the information analytic skills influence the levels of pursuit of truth, openness, and objectivity, (3) the information presentation and delivery skills affect the levels of inquiring mind, organization, and self-trust, and, (4) the information evaluation skills influence the levels of pursuit of truth, openness, inquiring mind, organization, objectivity, and self-trust. However, students' synthesis and application skills of students did not affect their critical thinking dispositions. To sum up, we observed the influence of information literacy skills on critical thinking dispositions. The results of this study provide foundations for maintaining and developing information literacy instructions in school libraries.
