The purpose of this research examined the relationship between the level of news usage on Influenza A(H1N1) and media users' behavioral intention toward health protection. Specifically, the study investigated causal relationships among exposure of media information on Influenza A(H1N1) as an independent variable, psychological protection motivation factors such as perceived severity, vulnerability, response efficacy, & self-efficacy as mediated variables and behavioral intention on personal and public health protection as dependent variables using structure equation model analysis. Self-reported questionnaires were administrated to 460 college students. The result indicated the followings. First, the level of news usage on Influenza A(H1N1) was not statistically significant on influencing behavioral intention toward personal and public health protection. Second, perceived severity, vulnerability, and self-efficacy were significant variables on behavioral intention toward personal health protection whereas perceived vulnerability and response efficacy were significant on public health protection. The function among factors in protection motivation theory is dependent upon whom protected from illness.

The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.

The amount of personal information has increased dramatically due to the prevalent use of smartphones and the rapid growth of social networking services. Under these circumstances, there has been a lot of efforts to obtain new information based on the overflowing personal data. The conventional character analysis method, which heavily relies on personal surveys, had some limitations in that it was difficult for psychologist to have a complete access to the surveyed results. When it comes to celebrities, however, it is relatively easy to access to their information through various media. Therefore there has been various researches that examined celebrities' personalities. On the contrary, not many studies have focused on analyzing the characteristics of the general public whose information is not so accessible. In this research, we suggest a method to analyze ordinary people's characteristics based on information available via their social networking services. This research focuses on developing a Facebook-native application, which examines the user's character type based on the posts shared in the user's Facebook page.

Recently, industrial values of big data as an important force of future society have been vastly paid attention. At the same time, more concerns about their private informations' disclosure online still echo around us, especially for them who have experiences of their personal information open online. This study aims to examine the questions; how people think about their personal information revealed online?; how much they have 'psychological reactance'?; what attitudes they have toward a certain governmental regulations on this? The findings of this study indicate that we should have more attentions to protect 'privacy' in the age of big-data and still need to make a lot of efforts to prepare a feasible regulation guide on this issue.

Guidelines for protecting personal information are already in progress in USA, UK and other countries and announced many guideline like HIPPA. However In Our national environment, we does not have specialized guideline in national medical industries. This thesis suggest De-indentification method in South Korea by referring 'bigdata De-identification Guideline by Ministry of Science, ICT and Future Planning (2015)', ICO in U. K and IHE, NIST, HIPPA in U. S. A. We suggest also correlation between Guidelines. Corelation means common techniques in three guidelines (IHE, NIST, HIPPA in U. S. A). As Point becomes closer five points, We recommend that technique to national medical institute for De-Identification. We hope this thesis makes the best use of personal information's development in National medical institute.

This study explores how the digital divide caused by personal SES(Socio-Economic Status) eventually affect personal life satisfaction. The study also investigates the differences between living in urban and rural areas, as well as the differences among generations, with respect to the digital divide and personal life satisfaction. Based on the Korean Media Panel data produced by KISDI, this study used 9,647 national samples to obtain variables such as digital divide, and life satisfaction. Results show that personal SES is a key factor that significantly influences digital divide and life satisfaction in various degrees. Also, the study finds that the degree of the digital divide have an effect on people's life satisfaction. The findings imply that people living in urban areas are more highly used to digital media than those in rural areas regardless of their SES. The study has an implication, in terms of digital equity among generations as well as urban and rural residents.

Utilization of unmanned aerial vehicles (UAVs) are rapidly expanding to various fields ranging from defense, industry, entertainment and personal hobbies. Due to the increased activities of unmanned airplanes, many security problems have emerged, including flight path errors to undesired destinations, secondary threats due to exposed securities caused by the capture of unmanned airplanes in hostile countries. In this paper, we find security vulnerabilities in UAVs such as GPS spoofing, hacking captured video information, malfunction due to signal attenuation through jamming, and exposure of personal information due to image shooting. In order to solve this problem, the stability of the unstructured data is secured by setting the encryption of the video shooting information section using the virtual private network (VPN) to prevent the GPS spoofing attack. In addition, data integrity was ensured by applying personal information encryption and masking techniques to minimize the secondary damage caused by exposure of the UAV and to secure safety. It is expected that it will contribute to the safe use and stimulation of industry in the application field of UAV currently growing.

Electrocardiogram (ECG) signals cannot be counterfeited and can easily acquire signals from both wrists. In this paper, we propose a method of generating a coupling image using direction information of ECG signals as well as its usage in a personal recognition method. The proposed coupling image is generated by using forward ECG signal and rotated inverse ECG signal based on R-peak, and the generated coupling image shows a unique pattern and brightness. In addition, R-peak data is increased through the ECG signal calculation of the same beat, and it is thus possible to improve the recognition performance of the individual. The generated coupling image extracts characteristics of pattern and brightness by using the proposed convolutional neural network and reduces data size by using multiple pooling layers to improve network speed. The experiment uses public ECG data of 47 people and conducts comparative experiments using five networks with top 5 performance data among the public and the proposed networks. Experimental results show that the recognition performance of the proposed network is the highest with 99.28%, confirming potential of the personal recognition.

The authentication process is a key step that should be used to verify that a user is legitimate, and it should be used to verify that a user is a legitimate user and grant access only to that user. Recently, two-factor authentication and OTP schemes are used by most applications to add a layer of security to the login process and to address the vulnerability of using only one factor for authentication, but this method also allows access to user accounts without permission. This is a known security vulnerability. In this paper, we propose a Zero Knowledge Proofs (ZKP) personal information authentication scheme based on a Smart Contract of a block chain that authenticates users with minimal personal information exposure conditions. This has the advantage of providing many security technologies to the authentication process based on blockchain technology, and that personal information authentication can be performed more safely than the existing authentication method.
