Among various joint ventures, International Construction Joint Ventures (ICJVs) have emerged as a popular approach worldwide to developing large scale projects through international participation. A model, based on economic analysis and represented by several hypotheses obtained from the analysis, will be developed. Furthermore, we will empirically test the hypotheses/model using Structural Equation Model (SEM). This research is expected to explain why there exist different organizational forms for ICJVs, and to develop a framework for choosing appropriate forms with respect to various characteristics of ICJVs.

The paper presents a novel DC grid connection topology and control strategy for doubly-fed induction generator (DFIG) based wind power generation system. In order to achieve the wind power conversion, the stator side converter and the rotor side converter is used to implement the DFIG control based on the indirect air-gap flux orientation, and a DC/DC converter is used for the DFIG system to DC grid connection. The maximum power point tracking and DC voltage droop control can also be implemented for the proposed DFIG system. Finally, a 4-terminal DFIG-based multi-terminal DC grid system is developed by Matlab to validate the availability of the proposed system and control strategy.

The dies & molds are a very economical production tool and a high value-added product because of its mass production capability compared to other production methods. Due to the very stiff international competitiveness, the industries meet many obstacles. At this moment, measured the status, the international trends and try to find the vision and strategy to promotion of the industry. In Korea, large portion of dies and molds are still low value-added and make large number of tools. In order to advance this industry to the high-tech area and gain competitiveness in the golbal marketplaces, effective means of resource investment and strategy should be properly provided.

The mathematical model of a three-phase voltage source pulse-width modulation (PWM) DC/AC inverter is non-linear, and in view of the traditional linear control strategy it can not meet the requirements of designing a high-performance inverter. What's more, when the loads are not pure resistive loads, the inverter further requires that the controller possess high-performance. This paper proposes a nonlinear control strategy for the inverter called Passivity-based Control. We can alter the inverter model in three-phase abc coordinate to two-phase synchronous rotating dq coordinate for establishing the port-control Hamiltonian (PCH) model for this system. We can control the distribution of energy in the system to achieve the control aim. Simulation results show that the passivity-based control method can make this system possess a level of high-performance that is both robust and dynamic.

In this study, the aim is to understand the strategy of video content production with the case of the baby shark development process of Pink Fong Company, the content is described about the successful planning and strategy of baby shark which has become a global content, and the main point describes the planning of the production process and marketing strategies for each country. The findings of the conclusions resulted in the application of the standards of globalization and the local understanding of culture as the main factors for content success. If the Pink Pong Company's method is applied through this, it is possible to apply what is the main issue of creative content production Reproduction in the future.

This paper is to explore that there are structural problems in the Korea-U.S. Free Trade Agrement negotiation by examining the Korean FTA policy and to introduce some alternatives to overcome them. The structural problem stems in part from the inefficient system in FTA policy making and its implementation. Most importantly, there is a lack of ex-ante consensus building among stake-holders. As an alternative to the current FTA policy, we suggest two things. First, we argue that an FTA negotiation strategy should correspond to Korea's overall industrial development strategy. Second, the National Assembly should play an important part for enforce of trade policies as a tool for advancing a comprehensive strategic measures.

The firms aim to acquire services and costs advantage from logistics outsourcing strategy. But it is very important to select optimum service provider. A checklist of the criteria for the evaluation of service providers follows : service quality, low cost, logistics information system, service network, financial stability, investments in plant and equipment, management attitude and lookout for the future strategic fit, cultural and psychological barriers etc. Also, a 8-step implement of logistics outsourcing strategy will be of help for maximizing benefits of logistics outsourcing. It follows : 1-step : logistics environment analysis, 2-step : check service provider availability, 3-step : logistics outsourcing determinant analysis, 4-step : select of optimum service provider, 5-step : contract with optimum service provider, 6-step : identify of remaining barriers, 7-step : performance of logistics outsourcing, 8-step : evaluation.

In these days the global software market is experiencing diastrophism due to globalization, convergence, and the spread of web 2.0. In particular, today"s global economy has entered the so-called "Globalization 3.0" era, and the world is evolving into a flat world where labor, capital, and resources are moving freely. In this rapidly changing global economy, the growth of the Korean economy is in a state of continuous decline. Particularly software industry is also suffering continuously slow growth due to market saturation and low service earning, which require urgent countermeasures. Therefore, the purpose of this study is: 1) to analyze the current industrial condition of the software industry, which have special characteristics differ from manufacturing industry; and 2) to analyze the major obstacles of local companies working in the software industry in order to cope with the recent changes in the global market environment and 3) to draw out the strategy for the domestic software industry in gangwon province in order to promote local software industry and to achieve globalization.

In conventional direct torque control (DTC) using space-vector modulation (SVM) of induction machine (IM) drives, at least three current sensors are needed. In this paper, a low-cost SVM-DTC strategy is proposed, in which only a single current sensor is used. The position of the voltage space vector is divided into two areas: effective and non-effective area. If it is located in the non-effective area, the voltage space vector will be shifted into the effective area with minimum distortion. Further, the switching frequency remains constant. The simulation is carried out on a MATLAB/Simulink platform and the simulated results verify the effectiveness of the proposed strategy.

There is no overdoing of enforcement of the importance of strategical mind which indicates future direction when management environment around organizations are variously changing. This document describers preceding and comparison research about competition strategy, competitive advantage and IT centered on organizations' common issue "Guarantee of Continuous Competitive Advantage" and researched various factors to determined if Information Technology is functioning properly through the cases of excellent organizations operating continuous competitive advantage Continuous competitive advantage's source is evaluating positively about resource based view which is described by innovation of business process. However, reality of operating continuous competitive advantage with difficult imitation of business process' "Time" "Complexity" is insufficient. Confirm how continuous competitive advantage is operated in reality by accepting easy application of "Simple Concise" business process. Confirm existence of information technology capability creating difficult imitation is functioning as a source of continuous competitive advantage, not Information Technology resource supporting business process.
