This study investigates and analyzes the diversity of menu in military meal services that are recognized by the soldiers who are familar with meal services, and suggests the implications on the results of the analysis. For the ranks of respondents in terms of demographic features, the sergeants and corporals were 43.2%(186) and 29.7%(128) apiece. It was identified that the diversity of menu and significant influences as 57.5%. Thus, it is necessary to diversity the menus more than the present menus to increase the satisfaction of new generation on military meal services. The most influential factor on the diversity of menu was the hard-boiled food as 29.9% among 15 items. Therefore, the first measure to intensify the satisfaction of soldiers on meal services is to diversity the hard-boiled food. Accordingly, this measure will contribute to relieve the most biggest complaints on the diversity of menu in military meal services. For this purpose, it is recommended to replace the kitchen work system consisted of kitchen polices with the non-officer system enabling the long-term service. The kitchen polices are transferred to the first reserve list when they are accustomed to their duties because the period of service is limited under the present kitchen police system. Therefore, the present kitchen police system has the problem that it can't overcome the limit in terms of the quality of meal service.

Objectives: This study was to develop a reliable and valid instrument measuring the reproductive health promoting behavior of undergraduates. Methods: The initial questionnaires were made of 106 items from four domains through literature review. All questionnaire items were revised by an expert group and a pilot test. Data were collected using the revised initial questionnaire of men's 58 items and female's 64 items from 634 male and 685 female undergraduate students. The collected questionnaires were analyzed by factor analysis using varimax rotation to evaluate the construct validity. Results: According to the gender, two measurement were invented and analysed separately. Four common factors consisting of 'safe sex', 'sexual responsibility', 'genital health management' and 'STD prevention' were discovered in both groups. The 'genital hygiene' factor was added as a female factor. Male students' scale was made up 4 factors 16 items and female students' scale was made up 5 factors 18 items. Cronbach's alpha for male scale was estimated to be .892 and female scale to be .882. Conclusions: This scale will make it possible to measure the level of reproductive health among Korean university students. This scale may be useful for developing effective methods of education as well as policy programs for improving the reproductive health of Korean university students.

Multiperiod portfolio selection problem attracts more and more attentions because it is in accordance with the practical investment decision-making problem. However, the existing literature on this field is almost undertaken by regarding security returns as random variables in the framework of probability theory. Different from these works, we assume that security returns are uncertain variables which may be given by the experts, and take absolute deviation as a risk measure in the framework of uncertainty theory. In this paper, a new multiperiod mean absolute deviation uncertain portfolio selection models is presented by taking transaction costs, borrowing constraints and threshold constraints into account, which an optimal investment policy can be generated to help investors not only achieve an optimal return, but also have a good risk control. Threshold constraints limit the amount of capital to be invested in each stock and prevent very small investments in any stock. Based on uncertain theories, the model is converted to a dynamic optimization problem. Because of the transaction costs, the model is a dynamic optimization problem with path dependence. To solve the new model in general cases, the forward dynamic programming method is presented. In addition, a numerical example is also presented to illustrate the modeling idea and the effectiveness of the designed algorithm.

Fueled by international efforts towards AI standardization, including those by the European Commission, the United States, and international organizations, this study introduces a AI-driven framework for analyzing advancements in drone technology. Utilizing project data retrieved from the NTIS DB via the "drone" keyword, the framework employs a diverse toolkit of supervised learning methods (Keras MLP, XGboost, LightGBM, and CatBoost) enhanced by BERTopic (natural language analysis tool). This multifaceted approach ensures both comprehensive data quality evaluation and in-depth structural analysis of documents. Furthermore, a 6T-based classification method refines non-applicable data for year-on-year AI analysis, demonstrably improving accuracy as measured by accuracy metric. Utilizing AI's power, including GPT-4, this research unveils year-on-year trends in emerging keywords and employs them to generate detailed summaries, enabling efficient processing of large text datasets and offering an AI analysis system applicable to policy domains. Notably, this study not only advances methodologies aligned with AI Act standards but also lays the groundwork for responsible AI implementation through analysis of government research and development investments.

The accident of the midair collision, passengers' falling or goods' dropping occurs or supersonic aircraft make a sonic boom during their conveying passengers or goods to the destination. The accident in transmit damages the their parties on the surface or their properties. In these cases, the third parties who were harmed to their lives or properties have the right to claim damages against the air carrier who caused them. These matters have become one of the important things since aircraft conveyed passengers and goods. Therefore, it is a great concern to settle these matters by law. But the Safety of the present aircraft has been much increased and the aircraft have become larger in size. Its flight altitude became higher than before. So the relationship of the aircraft to the third parties is much different from that of the earlier aircraft. The air transport is now indispensable to our life. It is not so easy to control these matters. In the early part of 20th century, when the third parties suffered the damage, many European countries made laws on the basis of the principle of liability without fault. But each country had a variety of its own law, and different kinds of difficulties have been brought about. Accordingly, the Rome Convention on Surface Damage (1933, 1952, 1978) has been made and revised. In spite of being revised, it contains many problems, and is not carried into effect world-wide. On the other hand, there are no regulations about the compensation of the third parties damaged in Korean existing laws. In case the damage is brought about to them, it is obviously true that the settlement of the liability of compensation for damage should be made by the general principle on the tort in domestic laws. At this point, it is urgent that we make a special law though the domestic legislation as a preliminary measure before we sign the international convention to save third damaged. It is desirable that we should, for the responsibility of the air carriage for the demage of the third parties on the surface, bring in the theory of the absolute liability in view of the legislation of many conutries. As the aircraft fly in the sky, their flight always contains some danger. It is very difficult to prove the fault, and the operator should suffer the principle of liability without fault or the similiar one. In case the liability without fault will be imposed upon the operator for the damage of the third parties, it is necessary to bring in the liability protection system for the protection and up upbringing of the air carriage. The Burden of danger of the air carriage will be reduced by introducing the system. A domestic legislation measure should be necessarily taken as soon as possible as a legal security measure on these matters.

The purpose of this study was to examine how married women with a child perceived the low-fertility issue in order to increase the success of policy decisions for increasing the fertility rate and to present alternatives. The study subjects were 327 married women with a child who resided in Dongjak-gu, Seoul. After the survey was conducted, the collected data were analyzed with SPSS 11.5 program. The findings of the study were as follows. First, the married women who already had one child found it ideal to have two children. In fact, however, 36.4% had determined not to have another child, and only one parent wanted to have a second child in 26.9%. Second, they took a dismal view of the government's fertility encouragement policies, and they considered it necessary for the government to pursue a more down-to-earth measure. Third, economic aid for child rearing and education was identified as the most critical way to boost the childbirth rate. In conclusion, current national policies aimed at increasing the low-fertility rate are redundant if they are only designed to publicize government action. Actions need to be taken to assist married women in taking better advantage of the existing policies.

Reducing fishing capacity is one of current issues in the international fisheries. This is because that increased fishing capacity has caused not only fish stocks to be depleted, but also additional fishing costs to be incurred, which resulted in reduction of economically viability of fisheries. For this reason, FAO adopted the International Plan of Action for the Management of Fishing Capacity' in 1999 and recommended member countries to estimate fishing capacity and to implement the policy to reduce fishing capacity. This study is aimed to measure fishing capacity of the Large Purse Seines Fishery that is one of offshore fisheries in Korea using both Peak - to - Peak Analysis and Data Envelopment Analysis in order to provide a policy information for preparation of domestic plan of action for the management of fishing capacity. The results of PTP Analysis were almost similar to those of DEA Analysis. The DEA results showed that the capacity utilization in 2004 was about 75%, it was obvious the capacity did not utilize enough. The sensitivity analysis on DEA results indicated that 24% of the number of ships, 26% of the tonnages, or 29% of the horse powers should be reduced if the present catch remained. In addition, if the catch remains at the MSY base level of large purse seines, the analysis suggested that the number of ships, tonnages and horse powers should be reduced by 15%, 18%, and 21% respectively.

The hospital standardized mortality ratio (HSMR) is a widely used generic measure for assessing quality of hospital care in many countries. However, the validity of HSMR as a quality indicator is still controversial. We critically reviewed characteristics of HSMR and suggested how to use HSMR as a quality indicator in the Korean setting. The association between HSMR and other quality measures of hospital care is inconclusive. In addition current HSMR model has shortcomings in risk adjustment because of the lack of clinical data, accuracy of disease coding, coding variation among hospitals, end-of-life care issues, and so on. Therefore, HSMR should be used as an indicator for improvement, not for judgement such as public reporting and pay-for-performance. More efforts will be needed to tackle practical and methodological weaknesses of HSMR in the Korean setting.

There is often confliction between conservation for protected ecosystem assets and development for various stakeholders at wetland protection areas. The concept of Ecosystem Services can be an alternative solution for the conflicts. This paper attempted to measure and evaluate cultural ecosystem services according to the index evaluation approach. For the evaluation, the paper suggested five indicators of ecosystem cultural services including: inspiration, landscape aesthetics, education, eco-tourism, and heritage. The developed indices of cultural services in this study can be also utilized as a policy support tool for conservation of the wetland protected areas. The result illustrates the ranking and correlation of each indicator of ecosystem cultural services and suggestions for useful means of management policy in wetland protected areas.
