The purpose of this study is to measure the cost-benefit of a road construction project in Vietnam through international development cooperation, which includes private grants and Official Development Assistance(ODA). In developing countries, it is difficult and costly to use data on markets, the CVM(Contingent Valuation Method) to measure the WTP(Willingness-to-Pay) as the benefits of road construction are used. A total of 232 villagers in 16 villages of Lao Cai Province in Northern Vietnam have been surveyed. It is found that the Benefit-Cost Ratio(B/C) in all 3 models are found to be well over 1.0, ranging from 2.8 to 3.64 with the discount rate of 0.06. These BC ratios imply the road construction project in Lao Cai can be justified. Also, it is found that the shortened travel time is the most relevant factor for WTP among direct benefits and the enhanced academic achievement of the children is the most relevant factor among indirect benefits, due to easier and faster access to schools, which in turn increase the school attendance rate. The result of this study can be used to justify other similar projects in Vietnam, even though the benefits may have to be reassessed in other countries.

During the last ten years, there have been many studies related with settlement and reinvigoration of CM. These researches have shown that the application of CM has been not reinvigorated in Korean construction industry yet, because of some problems such as the insufficient application of the public sector, the policy matters and the CM fee estimates. But the present condition data of the Korean CM Market shown in these studies was insufficient for the standpoint of Market itself. Also, some of these studies compared the Korean CM Market with The America CM Market, to study the foreign CM markets. However, because the Korea CM Market only has the CM for Fee Market but the American CM Market has the CM for Fee and the CM at Risk, the Korea CM Market must be not only compared with the America CM Market but also compared with the America CM for Fee Market. Therefore, the purpose of this study is to determine the present condition of the Korea CM Market through the compare and contrast of the Korean CM Market, American CM Market and American CM for Fee Market, by the Market Growth rate and Market Share. This study further aims to verify whether Korean CM market was implemented.

Although traditionally perceived as being a visualization and asset management resource, the relatively rapid rate of improvement of computing power, coupled with the proliferation of cloud and edge computing and the IoT has seen the expanded functionality of modern Digital Twins (DTs). These technologies, when applied to buildings, are now providing users with the ability to analyse and predict their energy consumption, implement building controls and identify faults quickly and efficiently, while preserving acceptable comfort and well-being levels. Furthermore, when these building DTs are linked together to form a community DT, entirely new and novel energy management techniques, such as demand side management, demand response, flexibility and local energy markets can be unlocked and analysed in detail, creating circularity in the economy and making ordinary building occupants active participants in the energy market. Through the EU Horizon 2020 funded TwinERGY project, three different levels of DT (consumer - building - community) are being created to support the creation of local energy markets while optimising building performance for real-time occupant preferences and requirements for their building and community. The aim of this research work is to demonstrate the development of this new, interrelated, multi-level DT that can be used as a decision-making tool, helping to determine optimal scenarios simultaneously at consumer, building and community level, while enhancing and successfully supporting the community's management plan implementation.

The housing market is divided into several sub-markets that operate independently. One of them is the distinction between rental and sales markets. Simultaneously, since the housing is a commodity as well as an asset, it has a close relationship between the rental market and the sales market. Due to the unique structure of Korea, it is difficult to apply the general method to analyze the housing market. This means there is a great deal of concern about side effects from the policy. Actually, the government's subsequent regulation of speculative demand in the future may be necessary to prevent market overheating, but at the same time, there is a fear that the rent will rise. Although changes in policy direction may be inevitable due to changes in market conditions, frequent and sudden changes in policy cause confusion in market participants, causing unrest in the housing market. This study aims to derive main factors and correlation with other housing market factor. These factors will be a base of qualitative housing market model to analyze the market effect of the demand-supply shift. Modeling is based on the system dynamics methodology, which is useful for identifying interactions between variables reflecting various variables in the housing market. The model discussed in this study is expected to provide integrated insight into the key variables of the housing market, away from the monopolistic thinking. It can also be useful as a means of assessing the effectiveness of policies.

본 논문은 한국건설 주가의 동태적 특성 -장단기 국내외 연계성-을 파악하기 위하여 작성되었다. 이를 위해 우선 한. 미. 일 증시 및 건설지수간의 상호 가격전이 메카니즘을 분석하여 국내 건설업 주가가 해외로부터 받는 영향을 추정하였다. 또한, 국내 주요 건설기업과 해외건설 지수와의 연계성을 살펴보고, 건설기업간의 주가변화의 상호작용을 실증적으로 분석하였다. 이와 관련하여 장기적 관계의 존재 및 미국과 현대건설의 리더십을 중심으로 한 일곱 가지 가설을 선정하였다. 장기적 균형가설 검정을 위해서는 Johansen and Juselius(1990)의 다변량 공적 분기법을 사용하고, 단기적 인과관계 추론을 위해서는 VAR 모형의 오차분산분해, 충격반응함수, 그랜저 인과관계검정을 일별 자료에 적용하였다. 분석결과는 다음의 네 가지로 요약된다. 첫째, 한. 미. 일 증시, 건설업지수, 국내 5대 건설사 간에는 각각 공적분 관계가 존재하지 않는 것으로 나타나 장기적 균형관계가설이 기각되었다. 둘째, 미국증시는 한. 일증시를 선행하는 것으로 나타났으나 건설업지수를 선행하지 않아 미국의 시장리더십을 건설업에는 파악할 수 없었다. 셋째, 현대건설주가도 국내 타 건설주가를 선행하는 것으로 나타나 현대건설의 시장리더십을 확인할 수 있었다. 이러한 실증적 분석 결과를 통해 한. 미. 일 증시, 건설업지수, 국내 건설주가는 단기적으로는 특정 국가 및 기업의 리더십이 발휘되지만 장기적으로는 상호 연관성 없이 독립적으로 움직인다는 사실을 알 수 있다.

An investigation was conducted to know a prospect of woody toy in Korea for physical, psychological and intellectual development. It was told that toys that stimulate cognitive development are appropriate for the child's capabilities, responsive to the child's movements, provide feedback when manipulated, and require imagination or fantasy. Toys particularly useful in the development of these abilities include dolls, figures, cuddly toys, puppets, costumes, and construction toys. Therefore, a toy is a wonderful object, indispensable to physical, psychological and intellectual development, both for those who have the capacity to integrate into society and for those who encounter difficulties. If we can replace a plastic toys by a environmental wooden toys, we can contribute to child development that is especially to promote creativity, artistic, problem-solving, language and social skills. In addition, we can support the ability of wood toy manufacturers to market their products in a responsible way and contribute to strengthen the competitiveness of our commodities on international markets.

최근 해외건설시장은 정체된 국내시장에 대한 대안으로서 국내 건설업체의 관심과 신규 진출이 지속적으로 증가하고 있다. 하지만 해외건설시장은 국내 시장에 비해 상대적으로 건설업체가 직면하게 되는 리스크 부담이 크기 때문에 시장 진출에 대해서 신중하고 합리적인 의사결정이 요구되고 있다. 이에 따라 기존의 많은 연구들이 관심이 증가하고 있는 개별 시장의 리스크에 대해 분석하고 있으며, 이를 고려한 시장 진출 의사결정 모델에 관한 연구도 이루어져 왔다. 본 연구에서는 건설기업의 입장에서 신규시장 진출을 재무적인 측면에서 고려하기 위한 모델을 제시하였다. 이를 위해 시장진출 시의 경쟁 상황을 고려한 실물옵션 게임 (real options game)을 통해 시장 모형을 도출하고, 이를 통해 해당 시장진출에 대한 투자 여부를 판단하기 위한 모델을 제시하였다. 본 연구를 통해서 도출된 시장진출모형은 가정을 통해 제약된 조건 상황 속에서의 특수 모델로서, 추후 연구를 통해 정보의 불균형성, 경쟁 기업 수의 일반화 등을 고려하여 보다 현실성 있는 모델을 제시하고자 한다.

For four decades now KEPCO has experienced an incredible growth rate of over 10% per year in each year. This growth led to the fast development of new facilities, especially in the transmission systems field, and we also managed to gain an enormous amount of experience and technology in the construction and design. With this experience and technology we curbed the electricity demand. Experts now predict that we will enter a new phase in which our growth rate will stagnate and eventually level off. This isn't what KEPCO or any company wants. We are looking for continued growth. In the last decade KEPCO began selling its technology in the generation sector of the electricity business to overseas markets. Sales in the generation sector have been a great success. This decade marks another milestone for KEPCO as overseas sales in the transmission sector began. Our first project, "Myanmar Power System Development Study" and its subsequent successful completion gave us the ammunition necessary to expand in this line of business. This success has also given birth to this paper. KEPCO is still the People's company, but with a new vision. It now hopes to not only sustain a high growth level but to also increase the growth of domestic companies by sharing with them a piece of the proverbial pie, as it ventures forth to be a Global player on the international stage.
