The contractor management for the effective defense project is essential factor in the modern defense acquisition project. The occurrence of Improper Businessman causes the reason in which defense acquisition project is unable to be reasonably fulfilled and setback to the deployment of defense weapon system. In this paper, we develop a prediction model for the effective defense project by using the Discriminant Analysis, the Logistic Regression & Artificial Neural Network and analyse the core variables that determine the Improper Businessman in many variables. It is expected that our model can be used to improve the project management capability of defense acquisition and contribute to the establishment of efficient procurement procedure through entry of the reliable domestic manufacturer.

When developers conduct a systems engineering approach the first problems that they will be faced are how to define and analyze the operational concept. In case of practical use project of MAGLEV train, those problems are also important since end products of practical use project must be assured for commercial service level. Lack of domestic developer's experience on systems engineering activity can cause a confusion a progress of the project. This study will propose a guide to establish an operational concept of project to develop or construct urban transit system.

According to the dynamic changes in the business environment, the structural transformation of firms has had an observable trend. An increasingly large number of firms have been transforming into either project-based organizations or project expert groups. This study aims to investigate the antecedents required for the optimal level of empowerment with consideration of the project-based team environmental nature and job characteristic. Three factors are applied to measure the significant effects on psychological empowerment as the result variables. To determine the antecedents and consequent factors of psychological empowerment, employees' interviews and precedent studies are used. For the empirical study, four determinants of empowerment variables are modeled into a second-order reflective construct. This study finds that psychological empowerment significantly affects performance. Therefore, this study can serve as a guideline for development and operating methods for project success.

There are many occasions on which the critical decisions should be made in software projects. Those decisions are basically related to estimating and predicting project parameters such as costs, efforts, and duration. The project managers are looking for methods to make better decisions. The decisions about project parameters are recommended to be performed based on historical data of Similar projects. The measures of the tasks in past projects may have different shapes of distributions. we need to add those measures to get a predicted project measures. To add measures with different shapes of distribution, we need to use Monte Carlo Simulation. In this paper, we suggest applying Monte Carlo Simulation for supporting decision makings in software project. We implemented best-fit case and scheduling estimations with Cristal Ball, a commercial product of Monte Carlo simulation and showed how the suggested approach supports those critical decision makings.

This paper attempts to analyse the financial validity of the Eco-therapy project which 'J' city in 'C' province has been eagerly trying to implement for its regional economic development and also to estimate the potential economic impact of the project on its regional economy. In doing so, it employs system dynamics which is a methodology for studying and managing complex systems, such as one finds in business and other social systems. Analytic framework for this study is constructed, based on the existing theoretical studies. This study concludes that the Eco-therapy Project concerned is economically and financially valid and it is also expected that the regional economic impacts arising from the construction and operation of the facilities concerned are greater than any other project which 'J' city has been pursuing.

Today, government is no longer considered the sole provider of public works or services. Public-Private Partnership (PPP) has been recognized as an important approach to solving problems for governments in providing public works and services. However, the joint ownership of public works/services complicates the administration of PPP projects. Particularly, the fact that government may rescue a distressed project and renegotiate with the developer causes serious problems in project procurement and management. This paper aims to study when and how government will rescue a distressed project and what impacts government's rescue behavior has on project procurement and contract management. A game-theory based model for government rescue will be developed. This pilot study, the author hopes, may provide theoretic foundations to practitioners/policy makers for prescribing creative PPP procurement and management policies and for examining the effectiveness of PPP policies.

The Korean Veterans' Pension Fund has previously pre-purchased Gibril Tower on Business Complex in Dubai, UAE, via a project-financed construction investment. Although the property is near completion, the investor syndicate's attempt to debt-finance due arrears was foiled in Dubai central bank's credit control of real estaterelated loans. Accordingly, the investment coordinator offered an additional capital injection, a collateralized leverage, and a maturity extension to the syndicate. If the syndicate rejects the offer, they may risk a nearcomplete capital loss and a possible default of the main contractor. Otherwise, the syndicate may still face uncertainties regarding interest receivables, principal re-payment, foreclosure, economic recession in Dubai, and the Islamic bond bill in the Korean Parliament. A possible exercise of the latter option may be due to the agency-prone nature of pension fund managers. Given these qualitative risk factors as at April 1, 2011, a real options approach-implied optimal decision suggests an extended and complete cash augmentation into the project finance deal.

현행 민간 시행사에 의한 주택 개발사업의 토지비 차입 구조는 사업자체의 타당성에 의한 진정한 의미의 프로젝트 파이낸싱(project financing)이라기보다는 담보능력이 약한 민간 시행사에 대하여 건설사의 지급보증을 필요로 하는(corporated financing)구도이다. 따라서 정확하지 못한 타당성 분석에 의한 사업진행은 사업 주체에 큰 타격을 줄 수 있으며, 더욱이 건설사의 경우 도급업체로서의 건설대금에 대한 리스크 외에 지급보증에 의한 리스크를 이중으로 부담하게 되어 치명적인 타격을 줄 수 있다 또한, 최근의 $8{\cdot}31$부동산 정책이후 분양시장의 환경 변화로 인해 정밀한 타당성 분석이 요구되어 지고 있다. 따라서 본 연구는, 이러한 상황인식 하에서 타당성 분석의 정밀도와 수지분석 항목과 관련된 사항에 대한 의사결정의 우선순위를 위하여, 지가에 따른 몬테칼로 시뮬레이션을 이용한 주택 개발사업의 사례분석을 통하여, 사업이익에 대한 수지분석 항목의 민감도 분석을 목적으로 한다.

In the 1960s, polluted urban streams were covered and paved in concrete. Rivers became sewers buried under road. As a result, wildlife habitat was lost and the open stream space was gone. In the 1990s, there was a movement for restoring urban streams to enhance the quality of life of inhabitants. Chungkye Stream, whose covering began from early 1950s and ended in 1977, is now in the process of restoration together with the Central Business District (CBD) Redevelopment Plan. However, as the construction proceeds, several problems were raised, and serious controversies resulted. Therefore, this study aims to investigate the validity of the approach of the Chungkye Stream Restoration Project through a literature survey and a site survey, and to present the improved alternative. Ultimately, the study aims to contribute to present references or guidelines for similar urban stream restoration projects. The Chungkye Stream Restoration Project has some of the following problems. First, the construction should be done based on the long-term urban redevelopment plan. Second, the construction period should be extended to restore urban streams. Third, the cultural asset conservation plan should be implemented. In order to fulfill the anticipated purpose, the above mentioned problems need to be solved.

China's Belt and Road Initiative infrastructure connectivity and other projects are presented in much of the discourse as a grand strategy to trap developing nations in debt, to exert asymmetric power and construct a new world economic order. The asymmetric relationship between China and Myanmar might therefore be expected to generate a range of political risks for stakeholders. Myanmar itself presents a "perfect storm" of problems, with dysfunctional governance, civil conflict, under-development and growing economic dependence on China. The Kyaukphyu port project and associated Special Economic Zone in Myanmar's troubled Rakhine state is investigated as a case study of risks on the Belt and Road. While worst case fears China might seize military control of the port appear unlikely, at least in current conditions, empirical observation indicates the complexity on the ground generates an array of other risks - as well as opportunities, should conditions allow. Further, despite challenges and constrained capacity, Myanmar governments have demonstrated agency, including by re-negotiating control and costs of the Kyaukphyu project. The case underlines that conditions are more complicated than simply China's asymmetric power. A sceptical approach is taken to normative discourses in order to build inductive understanding of how stakeholders and local experts perceive dynamics underway. A political risk approach is deployed to develop a framework to identify, analyse and assess risks for actors in relation to the Kyaukphyu project. The research findings are presented on an interim basis, given current constraints on field interviews due to the current crisis.
