Traditionally R&D evaluation has been performed by experts who can understand the contents of the study area very well. Recently extensive application of quantitative evaluation methods have been attempted for introducing the administrative management system that poses greater importance on records and results. More objective reviews on the R&D outcomes are called for gaining public supports. In this paper a bibliometrical analysis is to be performed to evaluate satellite communication and broadcasting public R&D outcomes for last 7 years. Data envelopment analysis method is selected for evaluating the efficiencies of multiple outputs (papers, patents, royalties, technology transfers) where multiple inputs (number of researchers and R&D expenses) are given. R&D outcomes from 22 research institutes are being compared and satellite communication and broadcasting R&D efforts turn out to be highly efficient.

HAPS(High Altitude Platform Station) which is defined as a station located on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the earth is promising technology capable of providing broadband multimedia services. In this study, economical aspects of HAPS service are analyzed by estimating the revenue and costs incurred by the service. To evaluate the profitability of HAPS service, the number of subscribers is estimated and then the net present value (NPV), payback period, and the rate of return on investment (ROI) are calculated under various scenarios

Judgment of alcohol blackout claims must be based on scientific, psychiatric, and psychological grounds, as because it is counterintuitive in that the action is performed but the memory is damaged. Nevertheless, the court does not specify the basis for the blackout judgment or gives reasons that seem somewhat unrelated, making it difficult to judge the validity of the judgment. Since the effects of alcohol on memory and behavior vary in cause and type, judgments on this should take into account clear concepts and the effects on decision-making ability and cognitive function. In this study, the author examined the Supreme Court's case that judged the blackout phenomenon in the Quasi-Indecent Act by Compulsion, and examined the problems and limitations of the debate in the case. Futhermor, the author overviewed the concept and types of alcohol blackout, the method of correctly interpreting the blackout phenomenon, and further research and practical work to be recognized as scientific evidence. The legal and theoretical implications for the justice system are discussed.

This study aimed to classify different types of child abuse perpetrators through the research titled "Study on the Current Status of Child Abuse and Research on Legislation for the Protection of Abused Children." The study analyzed data from 671 subjects and employed latent class analysis. The analysis used 11 variables related to the characteristics of the perpetrators (e.g. stability of residence, physical and mental disabilities, gender, and educational level) and characteristics of the incidents (e.g. repeat offenses, involvement of different types of abuse, and co-perpetrators). The results revealed three distinct types of child abuse perpetrators: organized, low-risk, and chronic/repetitive. The organized type predominantly consisted of female perpetrators who engaged in abuse collectively, while the low-risk type had a higher level of education and displayed a more proactive approach towards resolving incidents. The chronic/ repetitive type exhibited a greater risk due to more frequent mental health problems among perpetrators and a higher likelihood of reoffending. Based on these findings, practical interventions should take into consideration the specific types of perpetrators, and further academic research should focus on identifying risk factors associated with child abuse.
