  • This paper deals with performance measures for recoverable item control where the demand process is time-dependent. The performance measure is essential for modelling a multi-echelon inventory problem for repairable items. Most repairable items are expensive and have a great influence on the performance of equipments. Thus the information on these items is very useful to the decision maker. The purpose of this paper is to derive the system performance measure and the part(component) performance measure considering a cannibalization policy under the dynamic environment.

  • DMSMS (Diminishing Manufacturing Sources and Material Shortage) is increased by developing the scientific technique and downsizing the military part market. DMSMS affects the increase in total life cycle costs and serviceability. Therefore, advance control for parts is important to reduce the cost, and a database is needed to share information on the DMSMS. A task needs to be performed continuously by setting the major control item to management more efficiently. The purpose of this study was to deduce the major control item for the DMSMS management system. Thus, the pre-control item basis of the DAPA (Defense Acquisition Program Administration) Manual and the SD-22 Manual were first selected, and the results of the survey were analyzed by AHP (Analytic Hierarchy Process) method. Fifteen of the detailed items were stratified into three criteria (Impact, Probability, and cost of the DMSMS), and each weight for the items was calculated using a nine-point scale survey. The AHP survey was executed with 25 specialists in the DMSMS management field, and the score of consistency ratio over 0.1 was excluded. The model explained the results and suggested future directions for development.

  • Purpose: To examine the effect of menstrual self-management education program on knowledge and behavior of menstrual self-management in high school girls. Methods: With a randomized controlled trial, 100 high school girl students were randomly assigned into experimental group and control group. Menstruation self-management program was consisted of a total of four sessions of education program (1 hour of education per session). Control group only received the first class of education. Measurement tools were 20-item menstrual knowledge scale and 12-item women's genito-urinary hygiene scale. Pretest and post-test questionnaires were administered. Results: There were significant differences in menstrual knowledge as well as menstrual self-management behavior between the two groups. The experimental group showed significant improvement in both menstrual knowledge score (t=13.37, p<.001) and menstrual self-management behavior score (t=8.38, p<.001) than the control group. Conclusion: Results of this study suggest that the monthly self-management education program is effective in increasing the knowledge of menstruation of female high school students and enhancing their performance. This program needs to be implemented as a part of high school's standard sex education. Further study is needed to analyze follow-up effects of the program on self-management behavior of students after at least one menstrual cycle.

  • There are over 20 administrative rules related to Korea Foreign Trade Act including Export and Import Notification, Consolidated Notification, Notification for Strategic Materials and so on. The purpose of this research proposes to reform some administrative rules related to Korea Foreign Trade Act. First, the administrative rules are a little many and hidden in part, so the effort need for simplification and publication. Especially Export and Import Notification is no need more, and some articles can be transfer to the similar notification. Second, the prohibited or regulated items are only 135, and the reason is cooperation to world trade policy and Korea trade purpose. The item number of trade limitation are decreased sharply compare to several decades, but we still effort to decrease. Third, There are 2 tracks trade regulation both Korea Foreign Trade Act and 57 specific acts. The number of trade limitation item is over 5,000, so it is impossible to control by Consolidated Notification. The role of Consolidated Notification is the just guides for Export and Import, so trader has to use the specific trade-related law.

  • The aim is to find cyber measures in consideration of physical CPTED in order to prepare countermeasures for cybercrime prevention. For this, the six applied principles of CPTED were used as the standard. A new control item was created in connection with the control items of ISO27001. A survey was conducted on former and current investigators and security experts. As a result of the reliability analysis, the Kronbar alpha coefficient value was 0.947, indicating the reliability of the statistical value. As a result of factor analysis, it was reduced to six factors. The following are six factors and countermeasures. Nature monitoring blocks opportunities and strengthens business continuity. Access control is based on management system compliance, personnel security. Reinforcement of territoriality is reinforcement of each wife and ethics. Establishment of security policy to enhance readability, security system maintenance. Increasing usability is seeking ways to utilize, periodic incentives. For maintenance, security education is strength and security-related collective cooperation is conducted. The differentiation of this study was to find countermeasures against cybercrime in the psychological part of the past. However, they approached to find in cyber measures. The limitation of the study is to bring the concept of physical CPTED to the cyber concept.
