Although online search engine service provide a convenient means to search for information on the World Wide Web, it also poses a risk of disclosing privacy. Regardless of such risk, most of users are neither aware of their personal information being exposed on search results nor how to redress the issue by requesting removal of information. According to the 2015 parliamentary inspection of government offices, many government agencies were criticized for mishandling of personal information and its leakage on online search engine such as Google. Considering the fact that the personal information leakage via online search engine has drawn the attention at the government level, the online search engine and privacy issue needs to be rectified. This paper, by examining current online search engines, studies the degree of personal information exposure on online search results and its underlying issues. Lastly, based on research result, the paper provides a sound policy and direction to the removal of exposed personal information with respect to search engine service provider and user respectively.

In this paper, the security behaviors and attitudes related with the personal information of teenagers were investigated using empirical data based on rational behavior theory and protection motivation theory. An experiment for teenagers was conducted on Excel and the statistical packages (i.e., SPSS 21.0 and SmartPLS2.0.M3) to see how self-efficiency, security attitude, security intention and individual innovation affect their security behaviors. The experimental results showed that the security behaviors and attitudes of teenagers between internet and information devices are closely related, and the social influences can affect personal self-efficacy and security attitudes. Finally, we can know that teenagers should recognize the importance of security and protect their personal information safely through continuous education and training so that they can be linked to security behaviors.

This study focused on university students' risk perception of cybercrime through media exposure. For this purpose, I tried to figure out the results of risk perception on cybercrime with 8 factors. As a result, the lowest type of cybercrime was internet fraud, and it was caused by media type and degree of exposure, where university students get information about cybercrime. There's a difference of students' risk perception by media type, news media was the best. Depending on the media of the environment, even in the area of cyber crime there is a difference of perception of risk for each individual. And it can be confirmed that the risk perception in response to the exposure of the media has changed.

Internet web pages can be classified by three major types such as texts only, images with texts and videos with texts. The purpose of this paper is to analyze how customers recognize and respond perspective of perceived risk and media richness with regard to design patterns of internet web pages. Additionally, we will examine the extent to which aforementioned factors affect customer satisfaction. Analyses with perceived risks revealed that customers feel less personal risks including performance, psychology and time/convenience when used web pages of text-images and text-videos, compared to text only based web pages. However, customers feel that web pages consisting of image-text or video-text have higher points in terms of symbolism and social presence in media richness, compared to text only based web pages. Finally, we showed that personal risk and text-based Web page negatively affect but symbolism and social presence positively impact on customer satisfaction. Therefore, this study suggests a clue that why video-based Web content did not grow different from many people's expectation.

The purpose of this study was to find whether ego-resilience shows mediating effects between risk factors and Juvenile Delinquency. The data was conducted by using the multiple regression analysis. The results of the study were as follows: First, correlations among variables of risk factors and ego-resilience on subordinate variable of Juvenile Delinquency were significant. Second, the personal risk factors and ego-resilience have a significant influence on Juvenile Delinquency, and ego-resilience showed mediating effects between the personal risk factors and Juvenile Delinquency. Third, school related risk factors and ego-resilience have a significant influence on Juvenile Delinquency, and ego-resilience showed mediating effects between school related factors and Juvenile Delinquency.

This study performed a quantitative risk assessment for hydrogen-CNG complex refueling stations. Individual and societal risks were calculated by deriving accident scenarios that could occur at hydrogen and CNG refueling stations and by considering the frequency of accidents occurring for each scenario. As a result of the risk assessment, societal risk levels were within the acceptable range. However, individual risk has occurred outside the allowable range in some areas. To identify and manage risk components, high risk components were discovered through risk contribution analysis. High risks at the hydrogen-CNG complex refueling station were large leakage from CNG storage containers, compressors, and control panels. The sum of these risks contributed to approximately 88% of the overall risk of the fueling station. Therefore, periodic and intensive safety management should be performed for these high-risk elements.

전자의무기록(Electronic Medical Record, EMR) 시스템은 기존에 수기로 작성하던 의무기록을 디지털화 한 것이다. 이는 다양한 장점이 있지만 의료인이 관리 도메인을 통해 환자의 정보를 세밀하게 수집할 수 있는 환자 개인의 프라이버시 침해 문제가 발생하게 된다. 즉, 관계자에 의해 의도적인 유출이 발생하거나 의료정보의 거래, 복제 등 위험성이 존재한다. 특히 일부 의료정보는 고용 차별이나 사회적 차별 등 환자에게 정신적 고통을 안겨줄 수 있다. 이러한 프라이버시 침해는 유전성 질환 유전자를 가진 사람에게 유전적 요인에 근거하는 고용 차별이 발생할 수 있다. 관련연구에서는 환자의 임상적(Clinical) 또는 유전적(Genomic) 정보가 자신의 신원과 연계되어 있다면 프라이버시 침해가 발생할 수 있음을 나타낸다. 이러한 프라이버시 문제로 인해 EMR 시스템에 기반을 둔 전자건강기록(Electronic Health Record, EHR) 시스템 또한 개인 프라이버시 침해의 위험이 존재하게 된다. 따라서 의료정보의 프라이버시 보호를 위해 부당한 고용 차별 보험 차별 사회적 차별로 연결될 수 있는 개인 의료정보의 유출방지, 타인에게 알려지고 싶지 않은 개인 의료정보가 무단으로 거래되지 않는 것을 보장해야 한다. 이를 위해 본 논문에서는 의무기록의 익명화를 통해 환자와 의무기록 간의 관계를 제거하는 여러 방법들을 소개한다.

본 논문에서는 현재 국내·외에서 개발되고 있고 이미 상용화가 되어 있는 PKI 기반인증 시스템에서 개인키의 로밍을 구현하고 특정 개인 컴퓨터에 개인키가 보관 되어있을 경우 발생할 수 있는 개인키의 불법 유출의 위험을 방지 할 수 있는 Roaming Key Management System의 개발 및 방안 연구를 목적으로 한다. RKMS 는 사용자의 인증서와 개인키를 개인 컴퓨터에 보관하지 않고 신뢰 할 수 있는 키서버에 저장함으로써 개인키 불법 유출을 막을 수 있고 개인키 로밍을 가능하게 한다. RKMS는 현재 발생되어 지고 앞으로 발생될 것으로 예상되어지는 인증서 및 개인키 해킹의 대안의 방법으로 사용되어 질 수 있다. 이를 이용하여 PKI 기반 인증 시스템의 향상된 안정성과 편리성을 구현하고 개인키 누출을 방지할 수 있다.

The current radiation risk assessment for occupational exposure is based on the measured exposure dose and health checkups of workers. This people-centered risk assessment may occur errors because absence of using personal dosimeter or unrelated health symptoms of individuals lead to difficulties in obtaining accurate data from workers. In addition, although the established legal upper dose limit was used as a reference for the assessment, it does not imply that this limit is the optimal dose of radiation workers should get; ALARA principle should always be appreciated. Therefore, a new risk assessment model that can take account of all the important factors and implement optimization of radiation protection is required at the national level. In this paper, based on the KOSHA Risk Assessment, we studied on the workplace-centered risk assessment model for radiation field rather than the people-centered. The result of the study derived a right model for radiation field through the analysis of the risk assessment methods in various fields and also found data acquisition methods and procedures for applying to the model. Multidimensional model centering on the workplace will enables more accurate radiation risk assessment by using a risk index and radar plot, and consequently contribute to the efficient worker management, preemptive worker protection and implementation of optimization of radiation protection.
