This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics integration. And this research analyzes the case study(Business of Strategy Group Unit) Survey involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each side to feel vulnerable to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the quantity of available supplies. As a result, We propose that a firm's e-logistics safe strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

Today, the management environments of intelligence firm are changing the way of production planning and logistics management, and are changing the process of supply chain management system. This paper shows the development of information system software for intelligence enterprises is used in supply chain management for robot engineering industry. Specifically, supply chain management system in this paper has been developed to analyze the impact of multi plant and multi distribution environment, showing the process analysis and system development of hierarchical assembly manufacturing industry. In this paper we consider a production planning and distribution management system of intelligence firm in the supply chain. We focus on a capacitated production resource and distribution volume allocation problem, develop a mixed integer programming model, and propose an efficient heuristic procedure using a genetic algorithm to solve it efficiently. This method makes it possible for the population to reach the feasible approximate solution easily. The proposed regeneration procedures, which evaluate each infeasible chromosome, makes the solution converge to the feasible approximate solution quickly.

Korea's main manufacturing industries, which have led its economy for the past three decades, are faced with a serious downturn and loss of competitive advantages due to the current economic depression, China's rise, and the drop of oil prices. Korean business firms must adopt the paradigm shift in their value strategies, along with a government-led industrial restructuring in order to gain sustainable competitive advantages. Business firms allocate their limited resources between value creation and value appropriation, however, what effect does strategic emphasis on value creation versus value appropriation have on a business firm's financial performance? This paper empirically addresses this issue by examining the effect of shifts in strategic emphasis on stock return. Furthermore, this study examines appropriate choices of strategic emphasis to gain differential financial performance. The data set used in this regression analysis comes from the KISLINE database of NICE Information Service. The variables that form the basis of this analysis are stock return, ROA, and Strategic Emphasis [(advertising expenditures-R&D expenditures)/assets]. The interactive effect with situational factors regarding the firm and the type of technological environment in which the firm is operating was also analyzed. Our results show that investors acknowledge a shift of strategic emphasis as a sign of stock valuation. In comparison to US, Korean business firms have weak value creation capabilities in high-technology industries, and weak value appropriation capabilities in low-technology industries. This proves Korean firms are fast followers in the global market. Our findings suggest that Korean firms have to adopt a balanced value strategy, nurturing value creation and developing value appropriation for overcoming the current economic downturn and becoming a first mover in the dawn of "Industry 4.0."

우리나라 기업들은 허근 경제 위기를 겪으면서 대외적으로 커다란 환경변화의 요구에 직면해 왔다. 사실 이러한 변화요구는 굳이 경제 위기가 아니라 할지라도 치열한 생존경쟁에 있는 현대의 기업들에게 있어서는 필수요소라 할 수 있다. 이에 대응하여 기업들은 구조조정, 혁신, 조직개선 등의 이름으로 다양한 변화노력을 기울이고 있지만 이와 같은 변화의 노력에 대해 그 진행과정이나 결과에 대해서는 현명한 검토가 있어야 할 것이다. 즉, 기업의 성장에 도움이 되지 않는 조직 구조는 오히려 기업에 역효과로 작용하게 되므로 기업은 가치를 높일 수 있는 조직구조를 갖추어야 한다. 이차 같은 현상은 일부 기업에게만 국한되는 것이 아니라 건설기업에도 마찬가지로 적용됨 수 있다. 따라서 본 연구에서는 효율적인 조직구조를 갖추기에 앞서서 건설 기업의 조직구조를 전략 및 경영성과와 비교${\cdot}$분석하여 조직의 특성을 파악하고자 한다.

선진국에서는 1980년대부터 MVNO가 도입되었고 우리나라 학계에서도 2000년대 초반 이미 도입 필요성이 제기되었다. 그런데 2000년대 후반 통신비 인하가 주요 정책이슈로 등장하면서 이동통신사업이 개시된지 27년만인 2011년이 되어서야 MVNO가 도입되게 되었다. 2015년 4월에는 MVNO의 가입자수가 504만명으로 이동통신시장 점유율이 9%에 이르고 있으나 아직 많은 문제점을 노출하고 있다. 급속한 성장의 이면에는 저렴한 통신서비스를 바라는 소비자들의 욕구와 때늦은 MVNO의 도입이 자리하고 있다. 그리고 이통사들은 우월적 지위를 누리고 있는 한편 자회사를 앞세워 알뜰폰시장의 확보에 나서고 있어 중소기업의 입지를 약화시키고 있다. 정부의 적절한 개입이 지속되어야 할 필요가 상존하고 있다. 정부당국은 세계적인 MVNO 흐름을 조기에 인식하고 신속하게 도입할 필요가 있었으며 향후 이통시장의 경쟁환경조성에도 충분한 노력을 기울여야 할 것이다.

It is no news that Nigeria's infrastructure challenge is enormous. In the global ranking, Nigeria ranked low in quantity and quality of its infrastructural provision which has a great impact on the ease of business transaction. Low investments in transportation have brought about the current infrastructural deficit. Recently, the Nigerian government has made effort to address at least to some extent the infrastructural deficit through Public-Private Partnership, but this has not yielded the desired result. Moreover, the sustainability issues relating to railway projects such as, emissions, noise pollution, ecosystem, and other environmental issues calls for urgent attention. Hence, this necessitated consideration on sustainability appraisal for the Chinese rail project in Nigeria. This study reviews sustainability of railway projects built by the Chinese firm in Nigeria with particular emphasis on the environmental and social impact of these projects. The study further identified issues and challenges in project implementation with a particular focus on civil dialogue and community engagements. A detailed literature search was conducted on railway projects and infrastructure by systematically reviewing selected published articles.The analysis of the selected articles identified sustainability issues and potential for improvement of Chinese railway projects and how they contribute to or inhibit competitiveness in the Nigerian railway market. From the literature searched, some of the projects constructed by Chinese firm revealed that there is economic and social impact of railway projects delivered by the Chinese firm in terms of capacity development and knowledge transfer potentiality. For instance, in the just concluded Lagos-Ibadan railway projects, the study gathered that the project brought about 5000 jobs and local staff were trained by the Chinese company, this will boost man power and local content capability. Also, it will significantly improve Nigeria's infrastructure and boost its economic development. The study suggests that Nigerian government should ensure and provide an enabling environment that is conducive for investment on the continent. Peace, improved security, and decent governance are the best conditions for sustainable transportation growth.

This study aims at proposing a direction of improving the efficiency in Korean information technology(IT) industry. In the face of re-engineering which has been done in most industries, it is very important to assess the validity of their restructuring or M&A based on the future efficiency. At first, by using the DEA/WINDOW, we will evaluate how the 30 firms are efficient for outputting their performance with respect to the profit realization and market ability. Then, in order to propose the direction of the efficiency improvement and suitable restructuring strategy, we will clarify how the efficiency of IT firms depends on their firm size. Finally, we will analyze their 'economy of scale' and also reveal how their economy of scale depends on the firm size based on return-to-scale(RTS).

The influencing factors of large-scale IT investment decisions are rarely investigated in an empirical perspective. We find out different behaviors in IT investment decisions according to the size of organization. Large scale IT-investment decisions (e.g. system downsizing) can be the outcome of decision-makers' motivation to adopt and control new IT systems- However, this phenomenon is salient in the large-sized organization rather than small-sized ones. Based on our investigation, we predict general IT decision-making behaviors in organizations when making IT investment decisions.
