To promote information service and to encourage active participation from the group categorized as the alienated class(group of people) this study suggests the basic concepts and strategy for the information services to alienated class who does not have full public library services. The paper classifies three separate groups of alienated groups, handicapped. poor(economically unfortunate group) and elderly group. The service shall consider their needs from their own Point of concern and interests. There are three distinctive considerations, infra structure(facility building, space. place). administrative consideration, and equipments. Infra-structure includes the planning of the space to facilitate the equipments and reference materials which will be control)ed and moderated by a librarian. Administrative service includes the development for the educational system between the end users and external experts. It also includes the individualized education system for each group Material and equipment consideration should include the each group's specific needs such as the infra-structures which is provided for the handicapped person.

This study was to investigate the user's effects on the avifauna in Sokri Mountain National Park. The survey was carried over 4 districts which were divided with main trail(valley, ridge), subtrail(ridge), un-used trail (valley) by line transect method from December 1989 to October 1990. The observed birds were 36 species and 570 individuals, these consist of 23 species for residents. 7 species for summer visitor. 2 species for winter visitor, 4 species for passage migrant. The average density of birds was 2.35 ea/ha., and main dominant species were Parus major minor, Porus palustris hellmayri, Parus varius varius and Sitta europaea amurensis in order. The observed frequency of wild birds was 3.4 times/km in average. No. of species, species diversity and observed frequency of summer and autumn were lower than winter and spring in 4 survey routes. Therefore, from now, in Sokri Mountain National Park manegement, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods of wild birds protection, especially in summer.

Because computer system is complex gradually from fast growth of the Internet and sudden increase of Internet user and scale is growing, and dependence for computer system is rising gradually, data damage by mistake or disaster is big enough to can not imagine. Usually is continuous if wish to inform through internet and must update data stably, we should manage so that precious data is not erased from sudden problem through periodic backup. Plan to protect data safely for this should be readied. This paper proposes system that can make effective backup environment because consider environment and achievement method in these data management side. That is, implements system that achieve data backup and restore selectively in internet. Backup and restore about data had stored through browser even if disconnect directly to server because it is possible connect in internet by advantage of proposing system are available. Also, This system can manage data stored to server more efficiently by using selectively both backup and restore two methods.

This study investigates the relationship between controllability, severity, unrealistic optimism and risk perception of risk factors related to location - based SNS services for smartphone users. For this purpose, I surveyed university students who had experience using location - based SNS service. The main results are as follows. First, controllability has a statistically significant effect on unrealistic optimism. Second, Severity had a statistically significant negative impact on unrealistic optimism. Third, Controllability did not have a statistically significant effect on risk perception, Fourth, Severity did not have a statistically significant effect on perceived risk. Fifth, Unrealistic optimism had a statistically significant negative impact on perception of risk. The results of this study will contribute to the prevention of privacy incidents and the protection of smartphone users by using location - based SNS service. On the one hand, future research will need to look at the relationship between unrealistic optimism and risk prevention or coping behavior.

According to the enforcement of the Cloud Computing Development and User Protection Act, a new paradigm called as Cloud Computing is coming to the fore among public and private domestic enterprises. Therefore, domestic companies should develop SaaS products specialized for the domestic market and try to preempt the IaaS market ahead of global companies. Now we are facing a necessity to combine all the cloud systems in Korean government to operate seamlessly in a harmony. In this paper, we will look at the prospect of future development of related industry through cloud computing concept and G-cloud's cloud management system (G-CMS). G-CMS can be seen as the first system to comprehensively manage heterogeneous Unix virtualization systems. G-CMS can also save costs by managing heterogeneous virtualization systems in data centers.

As society develops, the dissemination of microdata has increased to respond to diverse analytical needs of users. Analysis of microdata for policy making, academic purposes, etc. is highly desirable in terms of value creation. However, the provision of microdata, whose usefulness is guaranteed, has a risk of exposure of personal information. Several methods have been considered to ensure the protection of personal information while ensuring the usefulness of the data. One of these methods has been studied to generate and utilize synthetic data. This paper aims to understand the synthetic data by exploring methodologies and precautions related to synthetic data. To this end, we first explain muptiple imputation, Bayesian predictive model, and Bayesian bootstrap, which are basic foundations for synthetic data. And then, we link these concepts to the construction of fully/partially synthetic data. To understand the creation of synthetic data, we review a real longitudinal synthetic data example which is based on sequential regression multivariate imputation.

With the proliferation of information technology communication and smart device, the environment where contents are produced and distributed is changing. People can use the contents quickly and easily, and the content industry is attracting attention and creating newly added value by converging with other industries. Accordingly, there is a need for content-related companies to understand the quality of content perceived by users in order to succeed in content, and to use it strategically. Therefore, this study aims to examine the relationship between content quality factors, user satisfaction, and recommendation intention through empirical analysis based on an IS success model. The analysis was conducted using smartPLS3.0 based on a total of 301 survey responses. As a result of the study, it was found that content usefulness, accessible system quality, convenient system quality, service provider trust, and interaction had a significant effect on user's satisfaction. Perceived privacy protection had a significant effect on user satisfaction and recommendation intention. Lastly, it was found that user satisfaction had a significant effect on recommendation intention. The results of this study are expected to provide useful information and therefore content companies can understand about the quality perceived by users.

As the status of public certificates expired due to the recent revision of the Electronic Signature Act, electronic signature-based public certificates were also lost in the means of replacing resident registration numbers(RRN). As a result, public certification institutions have recently been designated by the Korea Communications Commission as identity verification service providers through a review of the designation of personal identity proofing agency based on alternative means of RRN. However, unlike existing RRN replacements such as i-PIN, mobile phones, and credit cards, the personal identity proofing process for applicants for certificates is different from existing alternatives. The proposed method shows that it is possible to protect users' personal information and provide universal, reasonable, and safe identification services by applying improvements to electronic signature-based personal identity proofing services.

Despite the fact that Internet users around the world watch YouTube every day, very few users accurately recognize the recommendation algorithm for search results, and Google and YouTube are not disclosing it. Researchers tried to explore the undisclosed algorithm of YouTube in a reverse engineering design method, find key factors, and check the logical structure in which media platform operators recommend keyword search results and arrange them on the screen. Therefore, researchers studied the basic content priority factors through several months of discussion and data collection, and tried to reverse engineer the influencing factors based on the recommendation results according to male and female gender among the collected keyword search results. Although researchers' design only analyzed some of the almost infinite level of data uploaded and viewed for more than hundreds of hours every hour, these exploratory attempts will study media platform algorithms in the future, understand the intentions of operators, and protect users. thought it could be done.
