Today, the phase of modem war is very different from past war. That is, the winning of war depends on the ability to obtain information and high technology. The purposes of this research are to propose an effective R&D governance model in national defense sector and to present R&D strategy for obtaining core national defense technology. As a part of collaborative innovation, the strategy to exchange R&D results actively between the defense sector and the private sector will be discussed. The main contribution of this research is dearly defining the concept of R&D governance in national defense sector and applying it to an actual case. The national defense R&D governance model proposed in this paper is based on the characteristics of national defense R&D which are different from other industries. The analysis of business success factors for national defense R&D through the T-50 case study is presented in detail. The T-50 case study reveals the importance of strategic intent, core technology knowledge base, organizational structure, and project management.

This paper tests Van Home's hypothesis, a negative correlation between degrees of operating leverage(DOL) and financial leverage(DFL). For an empirical analysis, we extract information from financial statements of manufacturing companies listed in the Korea Stock Exchange. Data extend from 1980 to 2001. The DOL continued to increase until 1997, but decreased dramatically after the IMF financial crisis. However, the DOL has been at a higher level than companies of other countries such as USA and Japan. The DFL has been maintained at a much higher level, as expected. The empirical results indicate a positive correlation between the DOL and the DFL, which is inconsistent with the VanHorne's hypothesis. To further investigate, we divide the whole sample into subgroups according to such management elements as asset size, level of leverages, earnings and cash flow. The results for sub-samples are different from those of whole sample. This indicates we need to incorporate specific managerial factors in order to correctly explain financial decision processes.

The objective of this paper presents the application of an "integrated urban flood modeling-runoff model, urban flood model and sewer system model-" in a highly urbanized area of Samcheok where is seriously inundated in 2002 and 2003. For this, we demonstrate how couple a 1-D hydrodynamic model of the river, a 2-D hydrodynamic model of the overland (surface) flow, and a sewer network model including each boundary conditions. In order to make data file for the model, topographic information like elevation and share rate of buildings are directly extracted from DEM or topographical source data without data exchange to avoid uncertainty errors. Furthermore, the research is to assess the impacts of Manning n and buildings influences to inundated depth by changing its share ratio from 10 % to 30 % in low-land urban area. As a results, we found out that the urban inundated depth was decreased by Manning n but increased by buildings ratio. The calculated results of inundation was similar with observed one in 2002 and 2003 flooding. Furthermore, the area was also inundated under not riverbank break case in 2002 flooding.

The subway is the transportation means most commonly used by the citizens of the metropolitan area along with the buses in the metropolitan area and major metropolitan municipalities. However, satisfaction with the signboards is low and the signboards need to be improved. In this study, we investigated the problem of guide signs of city hall and exchange area with L - shaped history structure for guide signs affecting route finding. As a result, it is necessary to confirm whether the moving distance is long and moving accurately to the desired destination due to the L - shaped historical structure in both the station and the alternate area. In both stations, the number of the guide signs, Problems such as installation position, height, other. In this study, the movement within the subway station is classified according to the space. The type of guide sign installation was defined, and the specific principles for guiding the movement route were proposed. This research is expected to be useful as an important basic data for the types and layout of subway stations.

The purposes of this study were to understand how franchisor's influence strategies influenced franchisee's boundary spanning behaviors and how franchisor's entrepreneurship influenced franchisee's boundary spanning behaviors. This study also analyzed whether franchisor's entrepreneurship played a moderating role in the causal relationship between franchisor's influence strategies and franchisee's boundary spanning behaviors. Based on a total of 698 self-administered questionnaires obtained from franchisees(food-service unit owners or managers) in Korea, frequency analysis, exploratory factor analysis, reliability analysis and hierarchical regression analysis were conducted. The research findings showed results that firstly, promise (${\beta}$=0.292), threat (${\beta}$=-0.256), recommendation (${\beta}$=0.200), information exchange (${\beta}$=0.359), request(${\beta}$=-0.097) and legalistic plea(${\beta}$=-0.137) had a significant effect on franchisee's boundary spanning behaviors and secondly, franchisor's entrepreneurship had a significant positive effect on franchsee's boundary spanning behavior. In addition, the effects of franchisor's promise(${\beta}$=0.168) and threat(${\beta}$=-0.075) on franchisee's boundary spanning behaviors were found to be partially moderated by franchisor's entrepreneurship. Franchisees wanted franchisors to execute a high level of entrepreneurship and deliver a promise in an influence strategy. Limitations and future research directions were also discussed.

A brand community refers to a group of people who have a passion and loyalty for the brand, and is attracting attention as an effective marketing strategy to increase brand equity because it actively tends to support and promote the brand without expecting compensation. The objective of this study is to identify factors that are needed for sustainable brand community management. Existing studies on brand community management have mainly been conducted by quantitative methods measuring consumer satisfaction and dissatisfaction towards brand community activities, however, this study applied qualitative methods using means-end chains and laddering approaches in order to deeply identify a consumer's desired value on brand community activities. An in-depth interview of 41 members of BTS ARMY, a representative example of brand community, has been conducted and analyzed. The result of this study is as follows. In order to encourage active brand community activities, it is important to provide brand community members with a variety of high-quality brand-related content for a unique aesthetic experience, and a forum where all members can interact and exchange information and ideas to enhance brand value and experience. Finally, to nurture a strong brand community as a partner to co-create brand equity, rather than just a fan community, it is needed to build an environment that fosters opportunities for brand community members to increase self-respect and fulfillment through their brand community activities.

The OSGi service platform has several characteristics as in the followings. First, the service is deployed in the form of self-installable component called service bundle. Second, the service is dynamic according to its life-cycle and has interactions with other services. Third, the system resources of a home gateway are restricted. Due to these characteristics of a home gateway, there are a lot of rooms for malicious services can be Installed, and further, the nature of service can be changed. It is possible for those service bundles to influence badly on service gateways and users. However, there is no service bundle authentication mechanism considering those characteristics for the home gateway In this paper, we propose a service bundle authentication mechanism considering those characteristics for the home gateway environment. We design the mechanism for sharing a key which transports a service bundle safely in bootstrapping step that recognize and initialize equipments. And we propose the service bundle authentication mechanism based on MAC that use a shared secret created in bootstrapping step. Also we verify the safety of key sharing mechanism and service bundle authentication mechanism using a BAN Logic. This service bundle authentication mechanism Is more efficient than PKI-based service bundle authentication mechanism or RSH protocol in the service platform which has restricted resources such as storage spaces and operations.

Financial Accounting Standards Board (FASB) Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes: An interpretation of FASB Statement No. 109, requires firms to evaluate uncertain tax positions and disclose information on their liabilities for these positions, unrecognized tax benefits (UTBs). We analyze the FIN 48 disclosures for calendar-year-end Korean companies listed on NYSE and NASDAQ and examine the Korean firms' tax aggressiveness utilizing the UTBs. The results suggest that stock exchange and firm size do not play a role in the Korean firms' tax aggressiveness, contrary to the matched U.S. firms and that the Korean firm in the miscellaneous retail industry is more tax aggressive than the firms in the communications, depository institutions and business services. In addition, we find evidence that the Korean firms are less tax aggressive than the matched U.S. firms. We also examine the Korean firms' tax avoidance tendencies using other measures of avoidance, leading to mixed results. Finally, we examine the association between the UTBs and other measures of tax avoidance and find a significant and negative association between the UTBs and the long-run cash effective tax rate.

This research analyzes the 4P(Police-Press-Politics-Public) model for establish an ideal relationship between press and police and suggests some practical policies. Through the examination of the relations among 4Ps(Police-Press-Politics-Public), Jean-Louis Loubet Del Bayle proposes 3 models from three aspets : exchange of information, relation of power, relation of legitimacy. The analysis of his models shows that politics and public give social and political legitimacy to police and press which, based on the legitimacy, thereby obtain necessary informations from external entities to fulfil their original functions. On the other hand, the inevitable relation of press and police with politics and public caused from their social functions, in turn, makes the relationship between press and police more complicated and delicate. This research concludes, the relationship between police and press should be well balanced for their successful social functions and benefits of the public. To this end, this study suggests that a specific press guideline which is imposed on press and police, must be prepared and that a specialized press office must be established in the police.

Local assemblers of agricultural products perform important distribution functions such as providing sales outlets, labor forces, market information, and financing, forward contracting, farming, physical distribution, and etc. However, their business activities are not transparent and producers are not effectively protected from unfair practices done by local assemblers. In order to enhance transparency and to increase effectiveness of governmental policies, local assemblers, which are mostly private management, should be organized as corporations. In order to organize corporations, the government should emphasize the importance of education and should provide corporations with governmental funds for improvement of agricultural distribution. Corporations should be developed to marketing cooperatives in the long run, and are requested to form their federations. It is also necessary to have transparent forward contracting system by local assemblers. In order to have transparent system, producers and local assemblers are guided to use standard contract forms and to operate offices handling unfair trade practices by local assemblers. We also need a place to exchange forward contracts, which can be developed to a futures market in the long run. In summary, local assemblers of agricultural products, which are mostly private management, should be developed to corporations and be operated by a transparent manner in order to protect agricultural producers and increase efficiency of trading.
