This study aims to suggest the ways to reinforce academic library's research support services for professors and researchers in Korea. For this purpose, this study collected the development plans of academic libraries in Korea, and analysed the plans for supporting research activities, and also analysed each library's homepage. And this research classified the research support services of academic libraries into eight types for further analysis. The types are 'subject guide', 'academic information literacy', 'research analysis service', 'research consulting', 'research ethics education', 'thesis writing guide', 'bibliography management program', 'interlibrary loan·original text copy'. As a result, it is shown that the most libraries emphasized 'custom-tailored user education' and marked it on development plan. As subsequent plans, libraries provided the action plans of 'expansion of scholarly DB instruction on each subject', 'expansion of custom-tailored research support services', 'construction of research support service system' one after another. This study suggests 'activation of subject guide service', 'expansion of academic information literacy programs for supporting research', 'introduction of research performance analysis services', and 'support for establishment of research ethics' as ways to strengthen academic libraries' research support services.

The age of big data has not only opened new opportunities for economic growth in various industries, but it has also created new problems related to personal information protection and privacy invasion. Given this situation, Korea's communications commission has proposed a big data guideline that specifies how companies should collect and utilize personal information in the big data environment. However, this guideline is more focused on industrial development than personal information protection, and it contains many features that conflict with personal information protection law as it currently exists. As a result, civic groups strongly oppose the guideline, as it may create serious privacy issues for subjects of information gathering. Thus, this paper analyses the limitations of the guideline by comparing it with domestic and foreign laws about personal information protection and privacy. We also discuss the direction of legalization and institutionalization with respect to the secure use of big data.

In this paper, 1-axis tracking mechanism of solar-cell panel, which is able to rotate from -90 degree to +90 degree for maintaining always perpendicular between solar-cell panel and sun, was analyzed. This paper propose the non-linear shaped guidance and analyze mathematical formulation of non-linear shape. This analysis shows that it is able to identify the non-linear shaped guidance. Especially, even though the length of rotating link have changed, the non-linear shaped guidance could be confirm with proper size. As effectiveness of this result, 10% efficiency rising is estimated compared to the conventional 1-axis tracking mechanism and also optimal non-linear shaped guidance can be suggested for various size of solar-cell panel. Therefore the flexible mass-production is possible for various size of non-linear shaped guidance.

Contrary to past critical infrastructure network, current critical infrastructure network is adopting IoT devices and efficient management system using the external networks. Using this system, productivity and management efficiency could be enhanced compared to past critical infrastructure network. But cybersecurity issue could be occurred at external network connection, so cybersecurity guideline is necessary. However, critical infrastructure organizations tend to use the cybersecurity guideline issued by government because it is hard to develop cybersecurity guideline on their own. But the government's cybersecurity guideline isn't suitable for the critical infrastructure network because it doesn't include critical infrastructure's specific characteristics. Therefor, we suggested the development method of cybersecurity guideline for the critical infrastructure network based on analysing cybersecurity guideline standards and critical infrastructure networks.

There are various cyber attacks on business PCs. In order to reduce the threat of PC security, we are preventing the vulnerability from being diagnosed beforehand. However, this guideline is difficult to cope with because the domestic vulnerability guide does not update the diagnostic items. In this paper, we examine the cyber infringement cases of PCs and the diagnostic items of foreign technical vulnerabilities in order to cope with security threats. In addition, an improved guide is provided by comparing the differences in the diagnostic items of technical vulnerability from abroad and domestic. Through 41 proposed technical vulnerability improvement items, it was found that various security threats can be coped with. Currently, it is mainly able to respond to only known vulnerabilities, but we hope that applying this guideline will reduce unknown security threats.
