In recent years, national R&D programs tend to become larger and more complicated, which necessitates strengthening the overall coordination of national R&D programs at the inter-ministerial level from the program planning stage. This paper looks into the status and problems of Korea's national R&D programs and proffers ways to improve the current system It highlights the problems shown in the process of the 2004 overall coordination and their rectification. First, various ad-hoc private-led committee brought about inefficiency in decision making process. Therefore, it is necessary to streamline such committees and strengthen the function of the Office of Science and Technology Innovation, Second, in view of the implementation of the overall coordination system, it is necessary to identify the problems in full detail that were raised in the course of the previous year's overall coordination so that new projects can be allotted minimal grades and follow-up activities can be efficiently put into execution. Third, it is necessary to establish standing committees for constant review and efficient utilization that will be devoted to reviewing programs overlapped and their linkage. Fourth, priority of investment regarding the nation's strategic policy direction should be reflected. Fifth, given the lack of performance-based evaluation system, it is necessary to develop macro and micro evaluation indices in conjunction with enacting the tentatively named "Performance-based Law." The overall coordination system of national R&D programs should be supplemented and further developed in relation to the aforementioned problems and their rectification in order to enhance the expertise, fairness, and efficiency of the nation's R&D coordination system.

By complementary integration of WLAN and UMTS, a Beyond third Generation(B3G) mobile network can be constructed to establish the fastest global roaming environments, There are 2 types of B3G networks: loosely-coupled and tightly-coupled, A tightly-coupled network demands lots of investment and considerable amount of time to construct. On the other hand a loosely-coupled network is more scalable and easier to implement than a tightly-coupled one, But it has critical drawbacks of packet loss and blocking of services due to handover delay, To alleviate these drawbacks this thesis proposes a vertical handover procedure between WLAN and UMTS, which is based on MAP of HMIPv6, Performance of the proposal is evaluated in terms of blocking probabilities, The proposed procedure based on HMIPv6 shows better performance than those based on MIP.

FRN (Full range Naphtha) is distilled from crude oil in a Naphtha Splitter Unit and is separated into the Light Straight Naphtha, Heavy Naphtha, and kerosene according to the boiling point in sequence. This separation is conducted using a series of binary-like columns. In this separation method, the energy consumed in the reboiler is used to separate the heaviest components and most of this energy is discarded as vapor condensation in the overhead cooler. In this study, the first two columns of the separation process are replaced with the Petlyuk column. A structural design was exercised by a stage to stage computation with an ideal tray efficiency in the equilibrium condition. Compared to the performance of a conventional system of 3-column model, the design outcome indicates that the procedure is simple and efficient because the composition of the liquid component in the column tray was designed to be similar to the equilibrium distillation curve. An analysis of the performance of the new process indicated an energy saving of 12.3% under same total number of trays and with a saving of the initial investment cost.

The Continuous Risk Profile (CRP) has been well known to be the most accurate and efficient among existing network screening methods. However, the classical CRP uses safety performance functions (SPFs) which require a huge investment to construct a database system. This study aims to suggest a new CRP method using average crash frequencies of homogeneous groups, instead of SPFs, as rescaling factors. Hierarchical clustering analysis is performed to classify freeway segments into homogeneous groups based on the data of AADT and number of lanes. Using the data from I-880 in California, the proposed method is compared to other several network screening methods. The results show that the proposed method decrease false positive rates while it does not produce any false negatives. The method developed in this study can be easily applied to screen freeway networks without any additional complex database systems, and contribute to the improvement of freeway safety management systems.

This study measures the efficiency of intellectual capital of Korea's banks, financial investment companies, and insurance companies using the Value Added Intellectual Coefficient (VAICTM) model, which was developed by A. Pulic and investigates into the relationship of each of VAIC's elements - efficiency of human, structural, and material capital -with business performance of the institution. we found, first, average VAIC and human capital efficiency(HCE) of Korean financial institutions during 2001 - 2012 were highest among banks, followed by insurance companies and securities firm. Secondly, in general, banks in advanced countries tend to have higher HCE and VAIC compared with the banks of developing countries. Thirdly, Korean financial institutions' HCE and VAIC are lower than those of Australia and even Taiwan and Thailand and have been on the decrease in recent years. This suggests that Korean financial institutions should enhance VAIC and HCE to build-up the international competitiveness.

In the past 20 years, passenger and cargo transportation performance at the international passenger ports in Korea have increased by 8.6% on the compound annual growth rate, respectively. The Korean government had expected to continue expanding the market of car ferries and the government included plans for the development of additional routes and lanes with neighboring countries such as China, J apan, and Russia as a part of the Plan of the Korean Ministry of Oceans and Fisheries in 2019. However, compared to the development of routes, the management and operation of passenger terminals are inefficient. The purpose of this paper was to introduce the overall improvement of the passenger terminal operating system that reflects the recent changes in the supply and demand of international passenger vessels and the needs of the government and private sector passengers. To this end, a basic survey was conducted on the status of operations and facilities at the Busan International P assenger Terminal and a questionnaire survey was administered on the subject of use. The results of the survey were analyzed using the IPA model. As a result of the analysis, three items in the operation sector, three items in the facility sector, and four items in the system sector of the Busan International Passenger Terminal were identified as in need of improvement. Based on the results, the need for investment to improve the international passenger terminal operating system is suggested.

The purpose of this study was to inves-tigate the economic performance of the textile industry for the Korean traditional clothes. The content of this paper had two pars; The first part was for the macroeconomic aspects such as location production employments and the produc-tion facilities of the textile industries. The second part was for the microeconomic aspects such as business type branding method fabric type R&D efforts sourc-ing and the distributional channel The major results were as follows: 1.) Most textile firms for the korean traditional clothes were located in Gongju for man-made fibers and in Jinju for silk fabrics. 2) The size of the textile industry in terms of the number of business produc-tion amount the number of employee de-creased during 1994 and 1995 due to the decreasing demand. 3) Over the half of the textile firms produced raw fabric products while only 20% of them were involved in additional dyeing and /or printing finish which re-sulted in low value added production 4) The R&D effort of the textile indus-try for the Korean traditional clothes was very low due to the market uncertainty lack of technological knowledge and most of all small size of the firms 5) Most raw materials for the textile in -dustry were imported with high(25%) tariff rates resulting in price increase and thus low competitiveness in the market. 6) The textile producers sole about the 70% of their products to the wholesalers while selling the rest to the retailers di-rectly. This showed the dual structure of the distribution channel in the textile products. These results suggested some implica-tions for the firms the policy makers and the researchers. The firms should develop new and improved products to increase and create consumer demand by intensive R&D efforts. The government policy ma-kers should give financial supports the firms with R&D investment and legal help such as lowing tariff rate for the raw ma-terials. The researchers from the academy could help the textile industry with the advanced technological knowledge and up-date information for the consumer fashion demand.

Purpose: Most of all studies regarding corporate social responsibility have been dealing with its direct performance. Many previous studies provided the evidence that corporate social responsibility activities directly affect firms' competitiveness or corporate reputation. However, there are no studies regarding the role of social capital between corporate social responsibility and firms' competitiveness. The present study aims to examine a mediating role of social capital between corporate social responsibility and corporate reputation. Research design, data and methodology: The structural equation model integrating corporate social responsibility, social capital, and corporate reputation was proposed with three hypotheses. Questionnaire including 15 question items for three concepts was designed. Data for testing hypotheses were collected from students and staff who had experienced the social responsibility activities of Korea Hydro & Nuclear Co. Ltd. SPSS and SmartPLS were used to analyze data. Results: All three hypotheses were supported at the significance level of 0.01. Corporate social responsibility have a significant influence on social capital as well as corporate reputation. Social capital plays a mediating role in the relationship between corporate social responsibility and corporate reputation. Conclusions: The present paper identified a missing link between corporate social responsibility and corporate reputation by validating an indirect effect of corporate social responsibility on corporate reputation through social capital. The present study contributes to finding the indirect link between corporate social responsibility and corporate reputation. Implications for academics and practitioners. The research model can be extended to analyze the relationship between corporate social responsibility and its performance. The present study sheds light on identification of a new role of social capital. Managers of firms have the opportunity to recognize the fact that investment recovery of corporate social responsibility results from social capital and corporate reputation in long-term rather than short-term. The results of this study offers an insight that managers can enhance customer loyalty. The process linking corporate social responsibility to corporate reputation through social capital implies that firms can realize spiritual marketing delivering authentic storytelling through corporate social responsibility. The present study has a limitation for generalizing of research results because the sampling came from a case of firm.

On January 27, 2005, the central government of the Republic of Korea designated Jeju Island as an Island of World Peace based on Article 12 of the Special Act for the Jeju Free International City, and the WHO designated Safe Community Jeju in July, 2007. Whenever an industrial accident occurs on Jeju Island, reports in the media raise the question of whether Jeju is a safe city or not. But due to the characteristics of construction sites in Jeju, it is very difficult to employ workers of a certain level. For the safety of workers, it is also thought that owners should make a decisive investment to introduce an education and reward system in order to improve the consciousness level of workers. This research focuses on first-aid on construction sites. It then surveys the level of construction safety management, and suggests improvements in construction safety control and first-aid.
