정부정책은 시장과 기업에 많은 영향력을 행사하기 때문에 정부정책에 대한 평가는 중요한 현안이다. 현재 우리나라에서 CM정책을 제시하는 대표적인 자료는 건설산업기본계획과 건설기술진흥기본계획으로 이를 통해 정부의 CM정책을 이해할 수 있다. 본 연구의 목적은 제3차 건설산업기본계획과 제4차 건설기술진흥기본계획에 제시된 CM정책항목을 중심으로 CM정책에 대한 CM기업의 인식과 평가를 Gap 분석기법을 활용하여 중요도와 실행도의 관점에서 분석하고 주요 특징 및 시사점을 도출하는데 있다. 본 연구를 통해 나타난 주요 결과는 정부가 제시한 CM정책항목에 대해서는 전반적으로 중요하다고 CM기업이 인식하고 있는 반면 실행도에 대해서는 낮은 평가를 내리고 있다는 것이다. 향후 정부는 새로운 CM정책항목의 발굴보다는 이미 발굴되어 있는 CM정책항목의 이행전략과 성과점검에 보다 노력을 경주할 필요가 있는 것으로 나타났다.

본 연구는 혁신체제 전환의 의미와 동인, 그리고 혁신체제 전환과 관련하여 정부의 역할을 살펴보고, 구체적으로 추격에서 탈추격단계로의 전환에 따른 정책 및 행정체제의 변화에 대해 살펴보았다. 연구결과 선진국의 재빠르게 모방하던 추격단계에서 새롭게 경로를 창출하고 독자적인 발전경로를 만들어 나가야 하는 탈추격단계에 접어들면서 그동안 형성되어 온 정책 기제와 행정체제는 수정 변화되고 있다는 점을 알 수 있었다. 추격의 대상이 명확하게 주어지는 추격단계에서는 정부가 민간보다 우월적인 지위에서 직접 연구를 지원하거나 구체적인 정책방향을 제시하는 등 적극적인 개입이 이루어져 왔다. 반면 탈추격단계에서는 경로의 탐지 및 해결책 모색을 위해 정부와 민간간 파트너십이 더욱 강조되었으며 장기적 비전 창출과 광범위한 정책조정을 이끌어내는 전환가적 리더십이 요구되어 왔다. 행정체제 또한 주어진 문제를 효율적으로 해결하는 수단적 기제에서 벗어나 환경에 탄력적으로 대응할 수 있고 변화하는 수요에 민첩하게 반응할 수 있도록 분권적 다원주의 체제, 부처간 유기적 협조와 네트워크 강화, 정부민간의 상호교류와 협력을 강화하는 등 유기적인 구조와 관계를 강조해 왔다.

Recently, the demand of LED(light-emitting diode) lighting is gradually enlarged by governmental saveenergy policy, which the LED lighting has been established compulsorily in new buildings, public institutions, and residential installations etc.. The LED lighting is driven by SMPS (switching mode power supply). The SMPS requires high efficiency because the SMPS changes a commercial ac power source to low voltage dc power source. Harmonic components that occur in the conversion process of SMPS decrease system power factor and deal great damage in electric power system. To improve such problems, this paper proposes a SMPS of high efficiency. The switching devices in the proposed SMPS are operated by soft switching technique using a new quasi-resonant circuit. The input ac current waveform in the proposed SMPS becomes a quasi-sinusoidal waveform proportional to the magnitude of input ac voltage under constant switching frequency. As a result, the proposed SMPS obtains low switching power loss and high efficiency, and its input power factor is nearly in unity.

In this study, we tried to build a model which can deal with the efficient and effective operation of electric power industry, especially focused on the nuclear industry. Here, SD(system Dynamics) approach is used to visualize the underlying phenomenon of the nuclear power industry. SD is a methodology for studying and managing complex feedback systems, such as one finds in business and other social systems, The span of SD applications has grown extensively and now encompasses work in corporate planning and policy design, public management and policy, biological and medical modeling, energy and the environment. Recently, according to the report from KEPCO(Korea Electric Power Corporation), they are considering delaying a new power plant construction. It may be based upon business fluctuation downsized from Korean economic crisis in 1997 and freezing of construction funds due to unstable foreign exchange rate. At this point, we need desperately a kind of strategic model that would contribute to cope with the current business situation, energy generation, Production, and resulting Pollution. Specifically, this model, using SD approach, starts with the detailed drawing of influence diagram, which describes those relevant key points on nuclear power generation systems in electric power industry of Korea. These include such (actors as the operation of nuclear industry and parameters related to the decision making for business policy. Based upon the above-mentioned influence diagram drawn, we developed SD simulation model to evaluate and analyze strategic management of KBPCO. Based on our analysis, we could demonstrate how simulation model can be applied to the real electric power generation in Korea.

The year 2010 has been regarded as a year of China's assertive diplomacy. A series of China's behavior--including China's critical reaction to the U.S. for its sales of weapons to Taiwan, the Dalai Lama's visit to President Obama, China's arbitrary designation of 'core interests' over the South China Sea, China's inordinate reactions to the sinking of the Cheonan and Yeonpyeong bombardment, and China's activities in the Senkaku/Diaoyu island areas--has served as the witnesses to China's assertive diplomacy in 2010. The major causes of China's assertive diplomacy can be summed up by three factors: potential power transition from U.S. to China; emerging China's nationalism; and the recession of the Tao Guang Yang Hui as a diplomatic principle. But a majority of Western sinologists claim that China's assertive diplomacy is defensive in terms of its character. China's neighboring states, however, perceive its assertive diplomacy as diplomatic threat. Due to these states' geographical proximity and capability gaps with China, these neighbors experience difficulties in coping with China's behavior. In particular, China's coercive economic diplomacy, in which China tends to manipulate the neighbors' economic dependency on China for its diplomatic leverage, is a case in point for China's assertive diplomacy. China's assertiveness seems to be continued even after the inauguration of Xi Jinping government. Although the Xi government's diplomatic rhetorics in "New Type of Great Power Relationship" and the "Convention for Neighboring States Policy" sound friendly and cooperative, its subsequent behavior, like unilateral announcement of Chinese Air Defense Identification Zone (CADIZ), does not conform with its rhetoric. Overall, China's assertiveness has been consolidated as a fashion of its diplomacy, and it is likely to continue in its relations with neighbors. As a neighboring state, the ROK should approach to it with more balanced attitude. In addition, it needs to find out a new diplomatic leverage to deal with China in accordance with its security environment, in which China plays a growing role.

With the current global financial crisis, Korea's economic situation involves a great deal of uncertainty. As the construction industry in Korea has traditionally been one of the country's strongest engines of economic development, it is crucial to understand its current status when establishing government policy or corporate goals. Utilizing a variety of statistical data related to construction that has been published in Korea, this study analyzes the current status and performance of the industry in terms of technological development. Although it was found that the construction industry in Korea is currently unstable due to the influence of the global financial crisis, it is now expected to recover quickly thanks to the increase in the number of construction contracts in foreign countries. In addition, when the performance of national research and development is realized, it is expected that new construction technologies will contribute to the recovery of the Korean construction industry. Despite the benefits of construction contracts in foreign countries, there are harmful practices in the industry that need to be addressed, including the excessively fierce competition among domestic construction companies.

This paper deals with system thinking in the resilience of the SES (Social-Ecological Systems) around Mt. Gariwang, located in Jeongseon County, Gangwon Province, in particular with the disturbance that a new ski slope is planned to be built for the PyeongChang 2018 Winter Olympic. It first performs a literature survey and newspaper article search to summarize the controversy with regards to credible environmental and socio-economical impacts of the plan, and then elaborates a series of CLDs (Causal Loop Diagrams) to infer the dynamics of the impacts. The results imply that the natural restoration seems to be hard because the development activities can cause a great deal of damage to the ecosystem mainly due to soil degradation and the mitigation of icy valley effects with water exploitation for making artificial snow and so on. Moreover most of the households near the planned site seem to leave with land compensation, thus more policy efforts are needed to enhance the resilience of the ecosystem and the nearby society based on ecotourism.

Supply chain management (SCM) is an area that has recently received a great deal of attention in the business community. While SCM is relatively new, the idea of coordinated planning is not. During the last decades, many researchers have investigated multi-stage inventory problems. However, only a few papers address the problem of cost-optimal coordination of multi-stage inventory control with respect to service measures. Even published approaches have a shortcoming in dealing with a delivery lead time consisted of a shipping time and a waiting time. Assumed that there is no waiting time, or that the delivery lead time is implicitly compounded of a shipping time and a waiting time, the problem is often simplified into a multi-stage buffer allocation and a single-stage stochastic buffer sizing problem at all installations. This paper presents a simulation-based heuristic algorithm and a comparison with others for the problem that cannot be decomposed into a multi-stage buffer allocation and a single-stage stochastic buffer sizing problem because the waiting time ties together all stages. The comparison shows that the simulation-based heuristic algorithm performs better than other approaches in saving average inventory cost for both Poisson and Normal demands.
