Many companies have implemented ERP systems to enhance their process competitiveness. Since most ERP systems down to date are implemented and managed on each separated business-unit or company level, such systems run short of the consideration about global business processes and global system managements. In order to integrate a successful global ERP, it is essential to apply the well-systematic implementation methodology which considers global standardization and global IT requirements. It is, however, the actual circumstance that such well-structured methodologies for global ERP implementation are hardly shown not only from domestic site but from foreign one. This paper indicates the global ERP implementation guideline with integrated approach including; the standard process design for efficient execution of global business; the ERP implementation method considering global IT requirements; and, the management method for global system operation. GSI ERP methodology is composed of 3 Phase：Global Strategy Planning, Global Template Construction and Global Roll-Out. Phase1; Global Strategy Planning contains Environment Analysis, GSI direction and Implementation Plan. Phase2; Global Template Construction contains Business blueprint, GSI operation design and Global template implementation. Phase3; Global Roll-out contains local business analysis, local ERP implementation and Global ERP Operation.

The purpose of the present study is to build a model to determine the structure of long-term quasi-optimal rates of local and toll telephone services. The outline of this study is as follows : Telephone business, providing social goods, is capital-intensive industry which needs huge fixed cost to operate exchanges and telephone networks nationwide. The nature of above industry justifies the market structure of telephone business to be natural monopoly and makes a good reason for government's direct regulation, that is, price regulation. Three is a gap between the present rates and the quasi-optimal ones because some administrative processes intervene in rate making process before execution. On the above diagnostic basis, the present study made an empirical test for the optimality of present rates structure in connection with Ramsey-Boiteux model to maximize the sum of producer's and consumer's surplus and also the current study proposed a qusasi-optimal rates structure for better market performance. From the empirical analysis, we can deduce a policy recommendation the local price should be increased to 47% whereas toll price decreased to 24% in order to improve the net welfare worth of 32.6 billion won.

The purpose of this study was to investigate and evaluate the state of School Forest Movement by the School Forest Committee of the ‘Forest for Life’, and to provide schools and social communities with alternative, for activation through foreign and domestic case studies. School Forest Movement is very important and has great effect on many aspects, such as the improvement of school environment, the expansion of environmental education in school, the enhancement of local membership and increasing participation of school community. School Forest Movement has expanded from 10 schools in 1999 for pilot implementation to 20 in 2000. Now, it Is broadly recognized that the movement should be expended nationally A few problems were observed through pilot implementation. School community has little consensus away member and hardly participates in the movement, and the process is often underestimated, comparing to the result. For activation of School Forest Movement, school community should be cooperate to local community. Especially, the stepwise execution of School Forest Movement should be well organized and School Forest Movement should be changed into a process-oriented movement for more participation of school community including students, teachers, parents and.

This study analysed the influencing factors involved in deciding the policy through the analysis of procedure in the policy on the natural resources in local governments. To evaluate the political consensus of decision making in policy determination as political rationality in natural resources policy, we analyzed the degree of the satisfaction from the residents. Among the analysis factors of the satisfaction of natural resources policy, the most significant independent factors were the goal and the method of the policy, the institutional conditions and interested groups, the appropriateness of the content of decision making, supervising and controlling, cooperating relations, the effect of policy, and the consistency. From the analysis of the effect and the goal of policy, we found $70.5\%$ of residents was against the policy and only $27.8\%$ consented. Considering the appropriateness of supervising and controlling in accordance with the process of the policy decision and its execution, the influence of local governments and institutions concerned enjoying comparatively more economic benefits was strong, however, the involvement of the residents and supervising and monitoring institutions were found negligible.

The purpose of this study is to examine the policy direction and execution plans of the Japanese central and local governments for the use of vacant houses after the enactment of the "Special Act on Vacant Houses." It also seeks to provide suggestions for establishing vacant house policies in Korea by identifying the characteristics of the Japanese policies, and to suggest policy alternatives that can contribute to environmental improvement and regional revitalization through the use of vacant houses. For this purpose, we examined Japan's "Special Act on Vacant Houses," the process of establishing vacant house policies in the Japanese central and local governments, and the contents and direction of these policies. Below are the results of this study. First, the Japanese government revised mid to long-term policies related to housing after the enactment of the "Special Act on Vacant Houses", thereby providing ground for local governments to establish vacant house policies. Second, the government actively supported the operation and funding of related associations so that the private sector rather than the public sector could address vacant house problems. Third, the government subsidized administrative expenses such as cost of finding vacant house owners to prevent neglect of vacant houses, and showed its will to address vacant house problems by revising taxes such as property taxes and transfer income taxes. Fourth, the government has enacted distinct ordinances for each local government and made it possible to perform customized policies such as allowing residents and local stakeholders to participate in the establishment of vacant house policies. Fifth, the government made it possible to manage vacant houses efficiently by allowing the vacant house bank to provide all information related to the use of vacant houses. It is necessary for Korea's central and local governments to refer to these precedent cases and create efforts to reduce trial and error when establishing vacant house policies.

This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.

본 논문에서는 영상의 밝기 정보로부터 물체의 표면 형상을 재구성하는 새로운 접근 방법을 제시한다. 표면 재구성 문제를 최적화 문제로 정의하고 국지 해(local minima)에 빠지기 쉬운 기존의 경사법(gradient method) 대신 유전자 알고리즘(genetic algorithm)을 사용한다. 이를 위해 2차원 이미지에 적절한 유전자 표현 및 유전자 연산을 제시한다. 또한 입력 이미지를 단계별로 축소하고, 축소된 이미지에 유전자 알고리즘을 적용하여 큰 형상을 먼저 결정한 후 미세한 형상을 찾아내는 계층적 방법을 적용함으로써 유전자 알고리즘의 수렴 속도를 개선한다. 반사 모델로 기존의 람버션 반사 모델(Lambertian illumination model)에 거리 요소를 포함시켜 보다 현실과 비슷한 제약 조건을 주었으며 실험을 통해 제시된 방법의 타당성을 보인다.

The severe frontal crash tests are NCAP with belted occupant at 35mph and FMVSS 208 with unbelted occupant at 25mph, This paper describes the design process of occupant protection systems, airbag and seat belt, under the two tests. In this study, NCAP simulations are performed by Monte Carlo search method and cluster analysis. The Monte Carlo search method is a global optimization technique and requires execution of a series of deterministic analyses, The procedure is as follows. 1) Define the region of interest 2) Perform Monte Carlo simulation with uniform distribution 3) Transform output to obtain points grouped around the local minima 4) Perform cluster analysis to obtain groups that are close to each other 5) Define the several feasible design ranges. The several feasible designs are acquired and checked under FMVSS 208 simulation with unbelted occupant at 25mph.

Recently, multi-access edge computing (MEC) has emerged as a promising technology to alleviate the computing burden of vehicular terminals and efficiently facilitate vehicular applications. The vehicle can improve the quality of experience of applications by offloading their tasks to MEC servers. However, channel conditions are time-varying due to channel interference among vehicles, and path loss is time-varying due to the mobility of vehicles. The task arrival of vehicles is also stochastic. Therefore, it is difficult to determine an optimal offloading with resource allocation decision in the dynamic MEC system because offloading is affected by wireless data transmission. In this paper, we study computation offloading with resource allocation in the dynamic MEC system. The objective is to minimize power consumption and maximize throughput while meeting the delay constraints of tasks. Therefore, it allocates resources for local execution and transmission power for offloading. We define the problem as a Markov decision process, and propose an offloading method using deep reinforcement learning named deep deterministic policy gradient. Simulation shows that, compared with existing methods, the proposed method outperforms in terms of throughput and satisfaction of delay constraints.
