교량은 지속적인 규모의 증가와 노후화의 확대로 인해 전산화된 관리 체계가 요구되었다. 국내외 교량관리시스템(Bridge Management System; BMS) 개발 동향 및 기능의 비교, 고찰을 통해 생애주기 관리가 가능한 ICT (Information and Communication Technology) 기반 교량 관리 체계를 제안하였다. BMS는 인터넷과 모바일이 결합된 운영 체계에 GIS 기능과 객체 기반 정보 관리 체계를 바탕으로 개발되었다. BMS는 교량의 생애주기 동안 발생되는 모든 정보의 객체 기반 정보화를 수행하여, 생애주기 성능 변화와 소요 예산의 추정을 바탕으로 중장기 관리 전략과 단기 관리 계획의 수립을 지원한다. 실제 공용중인 교량 약 6천 개소에 대한 생애주기 관리 전략 수립을 통해 의사 결정 지원을 위한 유용한 지식 정보를 도출하였다. 전국의 모든 도로교량에 적용 가능하도록 개발된 BMS는 정확한 이력 관리를 통한 성능 유지, 합리적인 예산 관리를 통한 비용 절감, 현장 정보 수집의 편의성 및 신뢰성 증진을 위해 실제적, 실용적으로 활용될 수 있을 것으로 판단된다.

90년대 이후 전 세계적으로 지식경영(Knowledge Management : KM)에 대한 관심이 고조되고 있다. 특히 기업의 시장가치 중 지식자산이 차지하는 비중이 높아짐에 따라 한국의 건설 분야도 90년대 중반부터 대기업을 중심으론 지식경영을 도입하고 있다. 그러나, 중소${\cdot}$전문건설업체의 경우에는 기업의 재무 및 조직적인 이유로 지식경영에 대한 이해와 정보화에 뒤쳐지고 있는 실정이다. 더욱이, 건설 분야에서 중소${\cdot}$전문건설업체가 차지하는 비중이 매우 높게 나타나기 때문에 이들의 기술 수준이 건설공사의 품질과 직결된다고 해도 과언이 아니다. 따라서, 본 논문에서는 회사의 가치와 경쟁력 향상을 위해서 중소${\cdot}$전문건설업체들의 여건에 적합한 지식경영 전략 즉, 지식경영 도입 방안을 제시하고자 한다.

PURPOSES : This study evaluates the efficiency of snow removal operation resources using data envelopment analysis (DEA). The results of this study can help decision-making strategies, especially for resource allocation for snow removal works on national highways. METHODS : First, regional road management offices (DMUs) for efficiency evaluation were set up, and a database (for years 2012-2016) for analysis was formed. Second, DEA was carried out by selecting input and output variables based on the constructed database. Lastly, based on the results of the DEA, the efficiency of each regional road management office was evaluated. In addition, the potential for future improvement was determined. RESULTS : The results showed that there was a large variation in efficiency of snow removal operation resources by regional offices. CONCLUSIONS : The results of this study imply that the evaluation of efficiency for snow removal operation resources is important when decisions related to snow-removal strategies are made by road management offices.

To invigorate and develop marketing strategies in public performance, this thesis reviewed the literatures such as papers, academic materials and internet information on marketing in public performance. We performed surveys for specialists and non-specialists of public performance from on-line or off-line for questionnaire which is classified as demographic characteristics, tendency for seeing public performance and for knowledge of NFC and LBS, and analyzed the questionnaires for knowing the effects of NFC and LBS marketing in public performance. This thesis revealed generally a higher level of satisfaction with NFC than LBS, especially for specialists as compared with non-specilists. The reason of a lower level of satisfaction with LBS than NFC is that LBS technique has privacy problem about personal information by exposing the user location information. The reason of a lower level of satisfaction with NFC to non-specialists is that there are insufficiency of promotion for NFC technique and contents utilizing NFC. A total average score for a level of satisfaction of NFC and LBS service was revealed high as more than 3.50 out of 5.00. Through this thesis we suggest the public performance marketing strategies.

Climate changes have become the major issue for the sustainable society and the various regulation has been established for promoting low carbon and green growth in Korea. The paper industry as a large comsumer of energy is forced to cope with these regulation. In this study, the various examples were investigated for providing the basic schemes to develop environmental management strategies of Korean paper industry. The various cases to follow carbon economic were introduced and were categorized into five ways, for example, the carbon capture projects such as reforestation, the increasing the process efficiency, the resource recovery form process waste, the cogeneration systems, the application of non-woody biomass.

Fuel Cell Hybrid Vehicles (FCHVs) have already become the subject of major interest among automotive industry as well as power management strategies of FCHVs, as the fuel economy of FCHVs depends on them. There are several types of power management strategies of FCHVs that have been developed to improve the fuel economy of FCHVs. Among them, optimal control theory is applied to this study. A problem is defined and its objective is to minimize the energy consumption of an FCHV and to find the optimal trajectories of powertrain parameters during driving. Necessary conditions for the optimal control are introduced and the simulation results of constant costate are compared to that of variable costate in order to prove that the variable costate can be replaced with the constant costate.

The overall performance of multiuser systems significantly depends on how effectively and fairly manage resources shared by them. The efficient resource management strategies are even more important for multimedia users since multimedia data is delay-sensitive and massive. In this paper, we focus on resource allocation based on a game-theoretic approach, referred to as Nash bargaining solution (NBS), to provide a quality of service (QoS) guarantee for each user. While the NBS has been known as a fair and optimal resource management strategy, it is challenging to find the NBS efficiently due to the computationally-intensive task. In order to reduce the computation requirements for NBS, we propose an approach that requires significantly low complexity even when networks consist of a large number of users and a large amount of resources. The proposed approach linearizes utility functions of each user and formulates the problem of finding NBS as a convex optimization, leading to nearly-optimal solution with significantly reduced computation complexity. Simulation results confirm the effectiveness of the proposed approach.

Vietnam is gaining much attention as an attractive emerging market that can replace BRICs for the corporations who are destined to always look for a new market in order to secure competitive powers in the global market. The reason for Vietnam's becoming an attractive place for production is that much uncertainty has been found in China, which has been the traditional country that absorbed the most amount of capital investment. Also, the favorable conditions of Vietnam market itself and the environmental changes such as the open-door policy of Vietnam government attract the investment of Korean companies, and Korea currently holds the most amount of cumulative investments in Vietnam. However, it is necessary to remember that Vietnam is still a socialist nation, and many required components for corporate activities are not sufficiently provided in Vietnam market. Also, many unstable environmental factors exist such as the lack of infrastructure, the lack of many required institutions, the prevalent corruption, the excessive processing time and cost for adjusting the investment, the lack of advanced work force, and the underdevelopment of part and material industry. Therefore, those companies who are planning to invest in Vietnam should take a long-term perspective in planning the investment strategies, carry out a detailed market investigation and analysis in advance, diversify the investment areas and investment sectors, carefully make a joint venture and management, carefully determine the factory location, establish a local agency, make co-investments with the part suppliers, etc.

Purpose: By foreshadowing the historical background and cultural influence of Korean food and economic development in China, this paper demonstrates Chinese market entry strategies taken by TheBorn with its company history and CEO's background. Research design, data and methodology: The eclectic paradigm was utilized to analyze ownership, localization, and internalization advantages for TheBorn's first entry into the Chinese market. The research answers how TheBorn could expand its business in the early 2000s while most were skeptical about the globalization of Korean food. Results: First, possessing various restaurant franchises, food patents, and developments, and media use enabled to achieve a strong ownership advantage. Second, the Chinese market is conveniently located in South Korea. Thus, TheBorn could exercise direct management to its overseas restaurant to maintain the food quality and service. Lastly, establishing a sauce manufacturing plant and its branch company accelerated further expansions to other Chinese cities. Conclusions: Based on those success factors, TheBorn extended its business into different cities in China and emerged as a franchisor giant in the Korean restaurant franchise industry.
