With wide distribution of smart phones and development of mobile network, social network service (SNS) is displaying remarkable growth rates. Users build new social relations by sharing their interests, which brings surging growth to the SNS based on the combination between the strength of expanding the place for communication and distribution of smart phones featured with easy portability. This study is designed to understand impact factors of SNS on users in Korea and to conduct empirical research on casual relationship between the factors above and the factors affecting personal information behavior through the privacy protection and self-efficacy. In order to accomplish the objective above, the study presented a research model applied with key variables of the Health Belief Model (HBM) predicting behaviors capable of recognizing and preventing individual diseases in the field of health communication. To perform empirical verification on the research model of this study, a survey was conducted upon college students at N university located in Chungcheongnam-do and K university in rural area, who have experiences using the SNS. Through this survey, a total of 186 samples were collected, and path analysis was performed in order to analyze the relationship between the factors. Based on the findings from the survey, first, variables Perceived probability, Perceived severity, Perceived impairment of the HBM, key factors of personal information protection behavior on the SNS, were found to exhibit negative relationship with self-efficacy, and Perceived probability, Perceived benefit, Perceived impairment were found to exhibit negative relationship with privacy protection. But the above, Perceived severity showed positive relationship with privacy protection, and Perceived benefit and self-efficacy also displayed positive relationship. Second, although self-efficacy, a parameter, showed positive relationship with privacy protection, it demonstrated negative relationship with personal information protection behavior. Lastly, privacy protection exhibited positive relationship with personal information protection behavior. By presenting theoretical model reflected with characteristics of prevention based on these findings above unlike previous studies on personal information protection using technologies threatening personal information, this study is to provide theoretical and operational foundation capable of offering explanations how to predict personal information protection behavior on the SNS in the future.

In a broad term, health and medical data means all patient information that has been generated or circulated in government health and medical policies, such as medical research and public health, and all sorts of health and medical fields as well as patients' personal data, referred as medical data (filled out as medical record forms) by medical institutions. The kinds of health and medical data in medical records are prescribed by Articles on required medical data and the terms of recordkeeping in the Enforcement Decree of the Medical Service Act. As EMR, OCS, LIS, telemedicine and u-health emerges, sharing and protecting digital health and medical data is at issue in these days. At medical institutions, health and medical data, such as medical records, is classified as "sensitive information" and thus is protected strictly. However, due to the circulative property of information, health and medical data can be public as well as being private. The legal grounds of health and medical data as such are based on the right to informational self-determination, which is one of the fundamental rights derived from the Constitution. In there, patients' rights to refuse the collection of information, to control recordkeeping (to demand access, correction or deletion) and to control using and sharing of information are rooted. In any processing of health and medical data, such as generating, recording, storing, using or disposing, privacy can be violated in many ways, including the leakage, forgery, falsification or abuse of information. That is why laws, such as the Medical Service Act and the Personal Data Protection Law, and the Guideline for Protection of Personal Data at Medical Institutions (by the Ministry of Health and Welfare) provide for technical, physical, administrative and legal safeguards on those who handle personal data (health and medical information-processing personnel and medical institutions). The Personal Data Protection Law provides for the collection, use and sharing of personal data, and the regulation thereon, the disposal of information, the means of receiving consent, and the regulation of processing of personal data. On the contrary, health and medical data can be inspected or delivered of the copies, based on the principle of restriction on fundamental rights prescribed by the Constitution. For instance, Article 21(Access to Record) of the Medical Service Act, and the Personal Data Protection Law prescribe self-disclosure, the release of information by family members or by laws, the exchange of medical data due to patient transfer, the secondary use of medical data, such as medical research, and the release of information and the release of information required by the Personal Data Protection Law.

Industrial facilities are becoming bigger and more up to date, And a kind of the hazardous material used in the industrial filed is diversified. Therefore, serious accidents such as leakage of toxic materials, fire and explosion, is continuously occurred. There is Process Safety Management (PSM) system of the several preventive systems, but it is supposed to be a limitation to ensure safety or huge PSM industrial sites where have potential to catastrophically invisible and unexpected risks because it is still being managed by instruction and inspection of authority having jurisdiction other than self-regulating management differing from the primarily aim of PSM system. To verify safety management system of work-place, supplementation of existing system is urgently required. In this study, it suggests that PSM self-audit be emphasized significantly analyzing problems of the current systems for enhancing self-audit be emphasized significantly analyzing problems of the current systems for enhancing self-control safety through efficient self-audit management and improving the existing system and improving the existing as verifying the system there of, as well as studying methods which can support institutionally.

A test tool for self-leveling and flowing characters of coating materials used to semiconductors and electronic parts, especially for protection of LCD and PDP connectors, was designed, and the test tool was evaluated using polymeric siloxane coating materials which have various viscosities. The test results showed that the designed test tool was effective to measure self-leveling and flowing properties of coating materials. Therefore, considering that the viscosity is not directly correlated with self-leveling and flowing properties, we believe that this test tool will be a very useful tool for measurement instead of classical method using viscosities of coating materials. Particularly, the measurement of self-leveling and flowing properties using the test tool would be expected to be used in the area of selecting suitable protective coating materials for LCD (Liquid Crystal Display), PDP (Plasma Display Panel) and semiconductor connection parts.

This paper studied the effects of risk cognition of personal information and self-expression information on conation of privacy protection. In the first study, 88 college students who volunteered for this research were surveyed about risk cognition of personal information and conation to protect it. In the second study, after an information-seeking expert collected and organized the self-expression information that 88 volunteers had expressed on SNS, and then showed the organized self-expression information to 88 volunteers, and then 88 volunteers were surveyed about risk cognition of self-expression information and conation to protect it. As results of the first data analysis, the risk cognition of personal information had the greatest influence on non-disclosure of personal information, followed by reduction of the disclosure scope and law institutionalization requirement. As results of the second data analysis, SNS users openly expressed their opinion or life-style, but when they realized that self-expression information can be accumulated and become sensitive information, they had conation to protect their self-expression information such as non-disclosure, reduction of disclosure scope, and law institutionalization requirement. The implication of this study is that we have overcome the limitations of existing researches that can not explain information protection behavior on SNS.

The purpose of this research is to understand users' information protection behavior on personal information security from health psychology theory perspectives. Empirical results indicate that users' information protection behavior on personal information is predicted by perceived threat and perceived responsiveness. Perceived threat is determined by perceived susceptibility and perceived severity. Perceived responsiveness is determined by response efficacy and self-efficacy, but response cost is not significant. These findings provide an enriched understanding about users' information protection behavior on personal information security.

A self-regulating heating cable is an electrical heating element by flowing an electric current between parallel conductors filled with an extruded semi-conductive polymer. Self-regulating heating cables are used mainly for frost protection purposes because the construction is convenient and the price is low. On the other hand, structural problems with imperfections of the insulation can cause a fire despite their usefulness. This paper deduced a direct method to derive the cause by investigating the scene of a fire due to a self-regulating heating cable and analyzed the basic problem using fault tree analysis. In this paper, the actual fire scene was a cold storage warehouse, and fire investigation was conducted. After investigating the fire scene and fault tree analysis, the cause of the fire could be attributed to dielectric breakdown of the self-regulating heating cable. This paper could be utilized in the fire safety activities and similar fire investigations.
