The purpose of this study is to develop the Internet vulnerability index of adolescents. To do this, we used the original data of long - term follow - up survey for the internet overdependency cause analysis conducted by NIA in 2018, and analyzed the correlation between alternatives of internet vulnerability index and personal psychology by using linear regression analysis. Factor analysis showed that the relationship with the surroundings was indexed by adding 9 items to positive factors such as family acceptance, peer attachment, and teacher favorability. The relationship between the surroundings and self - stigmatization is confirmed, and the relationship between the surroundings and the Internet fragility is predicted to be negatively related, and the digital capacity is also assumed to be negatively correlated with the Internet vulnerability. In order to develop the specific form of the Internet vulnerability index, personal psychology and linear regression analysis were conducted. As a result, positive factors and R value of personal psychology were increased when considering the relationship with the environment and the digital capacity rather than the Internet overdependency model. Based on these implications, we discussed the implications and limitations of this study.

In archival science studies, personal archives is a relatively unexplored field. In particular, it is difficult to find a way for ordinary individuals to organize an archive for themselves. This study suggests how individuals organize archives for themselves and suggests life memory composition as a way to utilize them. For the structure and metadata design of life-time narratives archives, this study refers to Narratologie studies and memory studies of psychology, which are combined with the concept of hierarchy and collectivity of archives. In addition, the plot concept of the narrative was proposed to form a life narrative, which was used as a tool to construct one's own life narrative. Research into the composition and utilization of these life-time narrative archives may be helpful when individuals want to create archives for themselves in the future.

In this study, as part of the development of an autonomous flying personal aircraft, an equivalent model of the main wing assembly of an Optionally Piloted Personal Air Vehicle (OPPAV) was developed. Reliability of the developed equivalent model was verified by eigenvalue analysis. The main wing assembly consisted of a main wing, an inboard pod, and an outboard pod. First, for developing an equivalent model of each component, components to produce the equivalent model were divided into several sections. Nodes were then created on the axis of the equivalent model at both ends of each section. In addition, static analysis with unit force and unit moment was performed to calculate the deformation or the amount of rotation at the node to be used in the equivalent model. Equivalent axial, bending, and torsional stiffness of each section were calculated by applying the beam theory. Once the equivalent stiffness of each section was calculated, information of a mass and moment of inertia for each section was entered by creating a lumped mass in the center of each section. An equivalent model was developed using beam element. Finally, the reliability of the developed equivalent model was verified by comparison with results of mode analysis of the fine model.

With the rapid evolution of mobile devices and the development of wireless networks, users of mobile social network service on smartphone have been increasing. Also the security of personal information as a result of real-time communication and information-sharing are becoming a serious social issue. In this paper, a framework that can be linked with a social network services platform is designed using OpenAPI. In addition, we propose an authentication and detection mechanism to enhance the level of personal information security. The authentication scheme is based on an user ID and password, while the detection scheme analyzes user-designated input patterns to verify in advance whether personal information protection guidelines are met, enhancing the level of personal information security in a social network service environment. The effectiveness and validity of this study were confirmed through performance evaluations at the end.

The purpose of this study is to analyze and interpret the current situation of private security companies·guards for the past three years, security companies by size, general·special (new education), and qualification system provided by the Police Agency, Security Association, etc. It provides a theoretical foundation for private security and provides a new perspective for interpreting private security. As a result, through the current situation, this private security has a concentration of metropolitan area and facility security, an abnormal personal protection company contrast, the number of personal protection institutes, there is a special security shift to regular jobs, and the current continuous education On the other hand, the education of special security guards has been shown to be limited. In the qualification system, the utilization of security instructor qualifications and the utilization and public relations of personal probation officer qualifications will appear. The current state of typical private security is as follows. The first is the balanced development of private security and the clarity of business divisions. Second, the quality of private security education and educational institutions must be high. Third is the recognition of the qualification system and active public relations.

As the delivery industry grew around the restaurant industry along with the COVID-19 situation, the number of delivery workers increased significantly. Along with that, new forms of delivery using personal mobility (PM) also emerged and two-wheeled or PM-related accidents are steadily increasing. This study manufactures a PM's driving analysis device to establish a safe delivery monitoring environment. This system was constructed to process data collected from the driving analysis device and through a cloud server, which would recognize and record special situations (acceleration/deceleration, speed bump) that could occur during the PM's driving situation. As a result, the angular speed, acceleration, and geomagnetic values collected from the IMU in the device were able to determine whether to drive, drive on the sidewalk, and drive on the speed bump. This technology was able to achieve approximately 1600 times more driving information storage efficiency than conventional image-based recording devices.

The PRODUCE 101 (Chinese version《创造101》) program is an "Idol Nurture" reality show bought by China's Tencent Video from the copyright of the Korean PRODUCE 101 program. The program's "Idol Nurture" pattern is concentrated in the four aspects of the "Semi-finished" training objects, the complementary nurturing goals, the key points of storytelling, and the extreme empowerment of training subjects. The "Idol Nurture" process is fully presented through the programming of the training processes inside entertainment companies, and the foregrounding of the back stages of the recording, trainees and entertainment companies. The "Idol Nurture" pattern of the program has attracted great attention and has been applauded by many because it better satisfies audiences' diversion utility, personal relation utility, and personal identity utility. This pattern of "Idol Nurture" program can provide insightful reference and valuable experience to the development of other reality talent shows.

The Personal Information Protection Commission has been promoting the adoption of co-regulation to replace/improve the existing self-regulation programs since 2022. While the Commission's co-regulation framework has received positive feedback for its contribution to address the regulatory issues, it has also faced criticism for being seen as "co-regulation in appearance only without any real differentiation from existing self-regulation." This study aims to examine the case of industry-specific co-regulation proposed by the Personal Information Protection Commission, with the objectives of 1) determining whether their approach can be categorized as a type of co-regulation with differentiation from the existing self-regulation programs, and 2) proposing improvements for successful regulation. The 'co-regulation' of the Commission can be classified as a form of co-regulation that differs with traditional self-regulation, as it involves government and private organizations collaborating to establish self regulatory codes reflecting industry-specific characteristics as well as provides interest groups with incentives to comply with the codes. The co-regulation framework is evaluated to some extent as successful, but there is still room for improvement in three major aspects. (1) When selecting the areas for co-regulation, a focus should be placed on areas where technological changes are rapid, and government regulations should be applied in areas where they are not. (2) It is necessary to enhance the expertise of regulatory agencies, and (3) ensuring the democratic nature of regulation, such as encouraging the participation of civil organizations, is necessary.

Background: Assessment of the radiation doses to which workers are exposed can differ depending on the placement of dosimeters on the body. In addition, it is affected by whether the placement is under or over a shielding apron. This study aimed to evaluate the actual positioning of personal dosimeters on the body, with or without shielding aprons, among radiation workers in Korea. Materials and Methods: We analyzed the survey data, which included demographic characteristics, such as sex, age, occupation, work history, and placement of the personal dosimeter being worn, from a cohort study of Korean radiation workers. We assessed the use of personal dosimeters among workers, stratified by sex, age, working period, starting year of work, and occupation. Results and Discussion: Overall, high compliance (89.1% to 99.0%) with the wearing of dosimeters on the chest was observed regardless of workers' characteristics, such as age, sex, occupation, and work history. However, the placement of dosimeters, either under or over the shielding aprons, was inconsistent. Overall, 40.1% of workers wore dosimeters under their aprons, while the others wore dosimeters over their aprons. This inconsistency indicates that radiation doses are possibly measured differently under the same exposure conditions solely owing to variations in the placement of worn dosimeters. Conclusion: Although a lack of uniformity in dosimeter placement when wearing a shielding apron may not cause serious harm in radiation dose management for workers, the development of detailed guidelines for dosimeter placement may improve the accuracy of dose assessment.

The purpose of this study was to analyze and identify the higher-grade primary school children's needs for sexual education. We got the data with open question from 481 children from March to July 1999. We analyzed them according to the framework suggested by the Sex Information and Education Council of USA. The framework involves the six domains such as human development, relationship, personal skills, sexual behavior, sexual health, and society & culture. In the analysis of need for sexual education according to domain, need for human development was highest (79.2 ％), after that followed society & culture (8.3 ％), sexual health (5.8％), sexual behavior (3.6％), and relationships (3.1％). There was no need for personal skills. By topics, there were needs for puberty (38.0％), reproduction (32.5％), gender roles (6.0％), body image (4.9％), sexual abuse (2.4％) and reproductive health (2.4％). Girls and boys all mostly wanted to know human development 41.0 ％ and 38.2 ％ each. Society & culture (3.4 ％), sexual behaviour (2.7％), sexual health (2.6％), relationship (2.4％) were domains selected by boys. Girls wanted to know society & culture (4.9％) and 'sexual health (3.2％). Comparing by grade, fourth, fifth and sixth grade children are commonly interested in development, society & culture. Fourth grade children scarcely show attention on the relationship, sexual behaviour and sexual health; meanwhile sixth grade children would like to know sexual behaviour and sexual health. When their grade became higher, they would like to know more precise, concrete and deep information. We suggest that the textbook/guidebook for sexual health for the higher-grade primary school children should be developed considering the sex and grade.
