Defense R&D is an essential investment for the national security. Recently our nation has also begun to initiate a number of defense R&D projects. As a lot of fund and resources are allocated to these projects, we need to identify which projects to initiate and then how to manage these projects well. Though there have been a number of studies on R&D projects in commercial sector, there are only a few studies in defense R&D sector. Moreover, these existing defense R&D studies mainly deal with the former issues, which are occurring at the stage of project planing. We are more concerned with project management issues, such as how to manage projects that had already been evaluated to undertake at the planning stage. Specifically our study aims to identify project management factors leading to the success of defense R&D projects. Results of the empirical analysis indicate that management support, user-driven requirements management, and project planning capability are key elements for project performance.

One of the most fundamental problems in education in Korea up to yet is that teaching-learning activities in the classroom are carried out without considering each student\\`s interest, ability aptitude and other attributes. In 1995, National committee on Educational Reform of Korea recommended big changes on various aspects of the education system of the nation. In 1997, just before so-called the \\\"International Monetary Fund (IMF) crisis \\\" in Korea, Ministry of Education announced the seventh amendment of national curriculum. The foundation of new national curriculum is the implementation of a \\\"differentiated\\\" curriculum. Also, the new curriculum strongly suggests \\\"performance assessment\\\", which was introduced to the nation in mid 1990\\`s. However, most mathematics teachers have reluctant to both new curriculum and performance assessment.

Up to these days, hotels are assumed to compete each other. Due to the spread of high quality the hotel restaurants have begun to face an intensive competition. Hotel food at Beverage have become the more competitive along with fund, good price, service, quality food, and management know-how. It causes the hotel restaurants confront with management difficulties. In order to overcome the management difficulties, hotel restaurants have to improve their marketing abilities and especially to improve their service quality. For this, it is necessary fur hotel restaurants to investigate how their service providers and receivers recognize their service quality. In this research, we examined the cognitive three types of cognitive gaps among customers, service providers, and managers both on the service quality and on the positioning of hotel restaurants. Their cognitive gaps proved negatively correlated with hotel's performance. This research suggests the following findings. Firstly, the competitiveness of hotel restaurant depends on the accurate communication and consensus among managers, service providers, and customers. Secondly, using the information about cognitive gaps recognized, each hotel restaurant should develop concrete marketing plans and strategies with a careful consideration about its current competitive position and management condition.

Firm innovativeness and financing capacity are critical signals to stakeholders as they are key drivers of firm performance and competitiveness and indicate the firm's ability to fund its operations and growth initiatives. Based on signaling theory, this study investigates the signaling effect of a firm's innovativeness and creditworthiness and examines its signaling effectiveness. Using Korean innovation data and Korea Investors Service financial data for nine years, the findings indicate that a firm's technological innovation has a negative impact on its credit ratings, while non-technological innovation has a positive impact. Furthermore, a firm's credit ratings positively impact its performance. The current study contributes to the literature on signaling theory by exploring the signaling effect of a firm's innovativeness and creditworthiness. The findings provide insights for managers on how to send and monitor signals to stakeholders.

The purpose of this study is to analyze the efficiency of the policy direction to see if the government's purpose of relocating public institutions was achieved by analyzing the case of the Korea Housing Finance Corporation, which moved to Busan Metropolitan City in 2014. Based on the Korea Housing Finance Corporation's settlement management disclosure and public institution performance evaluation report from 2009 to 2019, efficiency was compared and analyzed using DEA analysis, work efficiency in management performance evaluation report, and financial ratio. The analysis results are as follows. First, in the case of DEA analysis, the difference in efficiency before and after fat transfer was not noticeable. Second, the efficiency analysis using the performance evaluation report and the financial ratio showed that the efficiency decreased after local relocation. Taken together, in the case of the Korea Housing Finance Corporation, efficiency decreased after local relocation, which can be attributed to sluggish business performance and inefficiency related to financial ratios. However, this study has limitations because it conducted an analysis on the Korea Housing Finance Corporation. To compensate for this, it is necessary to diversify the scope of research targeting all fund-managed quasi-governmental institutions in Korea. Nevertheless, this study is the first study to analyze before and after the relocation of fund-managed quasi-governmental institutions, and is expected to provide significant implications for future policies to be discussed.

Under complete information, introducing additional constraints to a portfolio will have a negative impact on performance. However, real-life investments inevitably involve use of error-prone estimations, such as expected stock returns. In addition to the reality of incomplete data, investments of most Korean domestic equity funds are regulated externally by the government, as well as internally, resulting in limited maximum investment allocation to single stocks and risk free assets. This paper presents an investment framework, which takes such real-life situations into account, based on a newly developed portfolio selection model considering realistic constraints under incomplete information. Additionally, we examined the effects of additional constraints on portfolio's performance under incomplete information, taking the well-known Samsung and SK group stocks as performance benchmarks during the period beginning from the launch of each commercial fund, 2005 and 2007 respectively, up to 2013. The empirical study shows that an investment model, built under incomplete information with additional constraints, outperformed a model built without any constraints, and benchmarks, in terms of rate of return, standard deviation of returns, and Sharpe ratio.

The present research is based upon the numerical analysis of a car windshield in order to represent the optimum design guide to improve the overall defrosting performance of the system. First, the control factors that highly affect the defrosting performance of a car windshield are chosen and afterwards, the optimum variables of each control factor are extracted out to analyze its performance. The main control factors for this research are respectively, the air injection angle of a defroster nozzle, the height of a nozzle outlet, and the ratio of the width to the height of a nozzle outlet. For such case when the air inlet angle is relatively small, the flow near the vicinity of the inner face of a windshield tends to expand. As a consequence, the heat transfer rate through the windshield decreases. Also, the height of a nozzle outlet is recommended to maintain its size to minimum. However, when the ratio mentioned before is designed less than unity, the defrosting performance decreases.

Purpose - The present study aims to examine the relationship between small enterprise start-up preparatory factors and increases in sales and operating profits, which are business performances utilizing the National Survey of Actual Conditions of Small Enterprises conducted by the Small Enterprise, Market Service. Research design, data, and methodology - Start-up preparatory factors were divided into six types; business type, start-up history, start-up motives, preparatory periods, and start-up funds to figure out the relationship between sales and operating profits with regression analyses. Regression analyses were conducted based on the foregoing with a view to identifying the effects of start-up preparatory factors on business performance. Results - Since start-up preparatory factors generally affect business performance, it was identified that start-up preparatory factors importantly affect operating profits and sales, which are business performances. However, start-up preparatory periods and the implementation of education among preparatory activities were shown to have no effect on business performances, and the effect of the ratio of start-up fund provided by the founder on operating profits was shown to be not significant. Conclusions - The present study comprehensively examined those start-up preparatory factors that have positive effects on business performances after start-up. The present study is meaningful in that it can provide positive implications for efficient start-up of small enterprises hereafter.

In this study, the effect of damping and elastic nature on the control performance of a safety budget-industrial accident rate model in Korea is examined first. The effectiveness of such dynamic model in establishing safety policies is shown with a simple proportional-integral(PI) feedback control mechanism. Control performance of the safety system model is explained in view of maximizing the effect of IAPF and minimizing the absolute amount of IAFP. Control performance is then evaluated and proved to be effective to prevent and reduce the industrial accidents. Implications in feedback control of a safety system model suggested to optimization of safety policies are also explored. Without proper restructuring of the safety system, it would not be possible to hit the target industrial accident rate. Even if the control objective is met, the amount of industrial accident prevention fund required to reduce the industrial accident rate from the current level to the target level would be far beyond the social consensus.

It is essential that the evaluation of official development assistance (ODA) projects is conducted based on empirical research for the performance and improvement of the project. This study intended to quantitatively figure out the actual status and performance of ODA projects. The performance of the Rumpin Seed Source and Nursery Center project implemented by the KOICA was evaluated in items of relevance, efficiency, effectiveness, impact, sustainability, which are OECD Development Assistance Committee(DAC) evaluation criteria. From August 26, 2019 to August 29, 2019, a survey was conducted on 50 visitors and 54 stakeholders of the Rumpin Seed Source and Nursery Center. Through on-site survey, problems in the donation project and operation in Indonesia were identified and measures for improvement was grasped. As a result of the study, the value scored by OECD DAC evaluation criteria of the Rumpin Seed Source and Nursery Center project based on the Economic Development Cooperation Fund(EDCF) evaluation grade was evaluated as a very successful class in all items. The average score of the recognition question was 4.08 points for visitors and 4.08 points for stakeholders, and the average score for the satisfaction question was 4.37 points for visitors and 4.11 points for stakeholders, which were high overall in both groups. The main factor that affects the project awareness of the visitors was the fact that the Rumpin Seed Source and Nursery Center was created based on Korean technology, and it was confirmed that Indonesia's own items related to similar projects had a great influence on the project satisfaction. In the case of stakeholders, project support in Korea affected their recognition, and it was found that relevance, efficiency, effectiveness items had the greatest impact on the level of project satisfaction of stakeholders derived from the DAC individual evaluation results. Efforts are required to increase the main factors by reflecting the results of each item and to preserve and maintain the project. This study is significant in determining the performance of the ODA project based on empirical data, and it is believed that it can be used as basic data for supplementing and strengthening the project in the future.
