  • The purpose of this study is to analyze the moderating effect of health privacy information on the relationship between the factors that affect the behavioral intention of the usage of u-health system have. Therefore, as a research hypothesis in TRA (Theory of Reasoned Action), self-efficacy and perceived usefulness will have a positive effect on the behavioral intention of the u-health system, and in the path, that personal information factors have an effect on each path. This study used the PLS-SEM methodology to verify the proposed research model. As a result of the analysis, this study showed that the moderating effect of health personal information in the presented model affects to some extent by the increase of R2 explanatory power. However, it was found that it was more consistent with the role of the independent variable rather than the moderating influence on the perceived usefulness.

There have been numerous studies to explore the problems and solutions, but these lack considering broader set of research variables. Therefore, this research investigated how i) internet users' self characteristics and ii) cognitive characteristics toward internet influence iii) internet addiction and iv) information ethics respectively. Especially, this study focused on college students, more mature beings than elementary, middle and high school students with whom most other researches have dealt so far. Major findings of this study are as follows: (1) Willingness to develop relationships over internet, usefulness of internet use, a degree to perceive the cyber space as real, and a degree to express self over internet have significant effects on disabled life style. Self respect willingness to develop relationships over internet, usefulness of internet use, a degree to perceive the cyber space as real, and capability of using internet have significant effects on the lack of control over internet. Willingness to develop relationships over internet, self control, and a degree to express self over internet have significant effects on the lack of control over internet. 2) Regarding the effects of independent variables(self characteristics and cognitive characteristics) on information ethics through internet addiction factors, self respect self control, a degree to perceive the cyber space as real, and capability of using internet have directly and indirectly significant effects on information ethics through internet addiction. Then we suggested four approaches to reduce the internet addiction and improve the information ethics based on the findings.

  • The current study extends previous research by investigating the role of shopping experience and product type within the direction of online reviews and information reliability and product attitude. To test the hypotheses, this study conducted experimental designs. Direction of online reviews and product type were manipulated as between-subject factors. Then participants were classified into high or low group based on their shopping frequency. Dependent variable was information reliability and product attitude. The results indicate that direction of online reviews have a significant effect on both information reliability and product attitude. In addition, consumers' shopping experience also shows a moderating effect between the direction of online reviews and the dependent variables. Furthermore, product type also shows a moderating effect on the information reliability, yet not on the product attitude. The results of this study contribute to the literature as a new attempt to examine the direction of online reviews in the online shopping area. We also indicated the limitations of this study, and suggested the future research directions.

  • SWF(Shock Wave Flash) file is a format file for vector graphics produced by Adobe. It is widely used for a variety of contents such as advertising at websites, widgets, games, education, and videos and it contains various types of data such as sound sources, script, API and images. Many SWF files contain URL information on action script for communication in the network and they can be used as important research data as well as PC users' Web Browser history in terms of forensic investigation. And a decompiler for analyzing SWF files exists by which SWF files can be analysed and URL information can be verified. However, it takes a long time to verify the URL information on action scripts of multiple SWF files by the decompiler. In this paper, analysis of URL information on action scripts and extraction of URL information from multiple SWF files by designing analysis tools for URL information in SWF files is studied.

  • To study the relationship between various information sources and first-to-market product innovation, this research examined how the internal and external information sources relate to first-to-market product innovation and how government regulations (economic, social and administrative) affect first-to-market product innovations, applying the perspective of Institutional Theory. For the analysis, variables used were first-to-market product innovation, internal and external information sources, and economic, social, and administrative regulations. This study was conducted based on survey data from the Korean Innovation Survey 2020 by the Science and Technology Policy Institute of Korea (STEPI). The data analyzed included small and medium-sized enterprises (SMEs) in the manufacturing industry, and a total of 586 firms were used from 2017 to 2019. By analyzing the internal and external information source and government regulations that have been relatively underexplored in previous research, this study suggests new directions and provides practical and managerial implications based on the results.

  • Augmented Reality (AR) is a mix of the real world that is enhanced by virtual objects from computer-generated information. AR is currently used in a variety of information systems and library services. AR technologies are also being developed for today's children, who are digital natives and are exposed to various technologies even earlier. To assist librarians who need to accurately understand users' information needs and perceptions of the technology being used in their libraries, we conducted a study of AR perceptions among children. We conducted two online co-design sessions using "Would you rather?", a co-design technique that facilitates research into children's opinions. Through the co-design sessions, we found that children were psychologically wary about AR technology due to a lack of trust in the technology, and realism had a significant impact on these judgments. We also identified that children considered AR technology environments as an extension of the real world. Their real-world values directly influenced their perceptions of AR. This research provides insights into the wariness that libraries need to be aware of when developing AR content for children in the future, and how libraries can use AR as an educational tool.

  • Recently, the amount of genome sequence is increasing rapidly due to advanced computational techniques and experimental tools in the biological area. Sequence comparisons are very useful operations to predict the functions of the genes or proteins. However, it takes too much time to compare long sequence data and there are many research results for fast sequence comparisons. In this paper, we propose a hybrid grid system to improve the performance of the sequence comparisons based on the LanLinux system. Compared with conventional approaches, hybrid grid is easy to construct, maintain, and manage because there is no need to install SWs for every node. As a real experiment, we constructed an orthologous database for 89 prokaryotes just in a week under hybrid grid; note that it requires 33 weeks on a single computer.
