With the rapid advancement and sophistication of defense weapon systems, the government, military, and the defense industry have conducted various innovative attempts to improve the efficiency of post-logistics support(PLS). The Ministry of Defense has mandated RAM-C(Reliability, Availability, and Maintainability-Cost) analysis as a requirement according to revised Total Life Cycle System Management Code of Practice in May 2022. Especially, for the project budget forecast of new PBL(Performance Based Logistics) business contacts, RAM-C is recognized as an obligatory factor. However, relevant entities have not officially provided guidelines or manuals for RAM-C analysis, and each defense contractor conducts RAM-C analysis with different standards and methods to win PBL-related business contract. Hence, this study aims to contribute to the generalization of the analysis procedure by presenting a cost analysis case based on RAM-C for the supply of military depot maintenance PBL project. This study presents formulas and procedures to determine requirements of military depot maintenance PBL project for repair parts supply. Moreover, a sensitivity analysis was conducted to find the optimal cost/utilization ratio. During the process, a correlation was found between supply delay and total cost of ownership as well as between cost variability and utilization rate. The analysis results are expected to provide an important basis for the conceptualization of the cost analysis for the supply of military depot maintenance PBL project and are capable of proposing the optimal utilization rate in relation to cost.

In recent years, demand for examination of bone mineral density (BMD) is increasing in Korea according aging society. Therefore, it is required to develop an efficient management program that can increase the safety and reliability of Dual Energy X-ray Absorptiometry (DXA) that can be applied to the criteria of the World Health Organization. It is necessary to develop a management program that can design a program to improve the accuracy and precision of the results of the analysis and to improve the accuracy of diagnosis of osteoporosis by development a high quality DXA report. It is recommended to prepare the examination manuals and to establish procedures of standard operating including the program to prevent the pitfalls during the examination, the compatibility evaluation of the examination data, and the contents of the radiation safety. In addition, relevant regulations on the production of high-quality DXA reports are required and government and related agencies should introduce individual and facility recognition programs through DXA measurement and education programs and training. It is considered that efforts should be made to prepare high quality DXA report by guidelines on all aspects of BMD for preparation about aging society.

This research aims to propose the necessity of conducting safety education to undergraduates majoring in social welfare studies and suggest a curriculum developing plan founded on social concern over safety along with its importance in the middle of changing welfare environment. I surveyed 12 experts with Delphi method conducted descriptive statistical analysis, and then verified reliability of the irresponses and validity of contents. As a result of the research, the curriculum was named as "Social Welfare and Safety" and proposed to be operated as "a regular course (3credits/3hours․2credits/ 2hours)". In terms of objectives and goals of the curriculum, 9 themes were proposed including "Establishment of safety awareness and necessity of safety management" and "Studying safety management methods depending on different types of facilities". For the curriculum contents, 20 themes were proposed including "Safety management by social workers" and "Countermeasures for safety accidents in social welfare facilities". In order for the new curriculum to be successfully conducted, follow-up studies should be conducted on details regarding operation of the curriculum such as curriculum operation manuals, curriculum guidelines, etc.

Objectives : The purposes of this study were to develop a mental health screening questionnaire and the practical intervention programs or guidelines which can be used in middle and high schools by students and teachers. Methods : The Adolescent Mental health & Problem behavior Screening Questionnaire II (AMPQ-II) was developed and was tested for reliability and validity using nationwide data from 2,180 middle and high school students and 2,145 teachers. Results : The AMPQ-II was measured by both students and teachers. The correlation coefficient of the test-retest test was 0.567 and internal consistency was high (Cronbach's alpha=0.878). Five factors such as worry and thought, mood and suicide, academic and Internet-related problems, peer problems, and rule violations were proposed. We also developed a practical guideline and manuals which can be easily used by secondary school teachers to screen for and manage mental health problems at school. Conclusion : The AMPQ-II can be a useful and reliable tool to screen for mental health problems in middle and high schools in South Korea.

Leading waste disposal countries, such as Sweden, Switzerland, and the United Kingdom, conduct safety assessments across all stages of High-Level Radioactive Waste Deep Geological Disposal Facilities-from planning and site selection to construction, operation, closure, and post-closure management. As safety assessments are repeatedly performed at each stage, generating vast amounts of diverse data over extended periods, it is essential to construct a database for safety assessment and establish a data management system. In this study, the safety assessment data management systems of leading countries, were analyzed, categorizing them into 1) input and reference data for safety assessments, 2) guidelines for data management, 3) organizational structures for data management, and 4) computer systems for data management. While each country exhibited differences in specific aspects, commonalities included the classification of safety assessment input data based on disposal system components, the establishment of organizations to supply, use, and manage this data, and the implementation of quality management systems guided by instructions and manuals. These cases highlight the importance of data management systems and document management systems for securing the safety and enhancing the reliability of High-Level Radioactive Waste Disposal Facilities. To achieve this, the classification of input data that can be flexibly and effectively utilized, ensuring the consistency and traceability of input data, and establishing a quality management system for input data and document management are necessary.
