  • This study reports on the motivational use of special libraries from a user's perspective that investigated four motivational components: attention, relevance, confidence, and satisfaction (ARCS) of the library users. Even though special libraries received relatively little attention compared to public libraries, special libraries could fill the niche of public libraries for the special and specific needs of the community in the current library environments in South Korea. Qualitative data were collected through individual interviews and forty people participated in the project. The findings of this study show the four themes (ARCS) that users need motivation as a way to start using a special library, thereby staying focused and revisiting the library. It is possible that the ARCS model will contribute to the implementation, application, and practice of both special libraries and their services in the library environment. The results are expected to expand our knowledge on the motivational ARCS use of special libraries and to serve as basic data when designing motivational strategies and plans of the systems for special libraries.

  • Since risks occurring in construction projects can have a significant impact on schedules and costs, there have been many studies on this topic. However, risk analysis is often limited to only certain construction situations,and experience-dependent decision-making is therefore mainly performed. Data-based analyses have only been partially applied to safety and contract documents. Therefore, in this study, cluster analysis and a Word2Vec algorithm were applied to formal documents that contain important elements for contractors or clients. An initial classification of document content into six types was performed through cluster analysis, and 157 occurrence types were subdivided through application of the Word2Vec algorithm. The derived terms were re-classified into five categories and reviewed as to whether the terms could develop into potential construction risk factors. Identifying potential construction risk factors will be helpful as basic data for process management in the construction industry.

  • Considering that earlier stage of construction project has a great influence on the possibility of lowering of environmental load, it is important to build and utilize system that can support effective decision making at the initial stage of the project. In this study, we constructed an environmental load estimation model that can be used at the early stage of the project using basic design factors. The model was constructed by using the artificial neural network to estimate environmental load by applying to planning stage (ANN-1), basic design stage (ANN-2). The result of test, shows that average of absolute measuring efficiency and standard deviation of ANN-1 and ANN-2 were 11.19% / 5.30% and 9.59% / 3.09% each. This result indicates that the model using the input variables extended with the project progress has high reliability and it is considered to be effective in decision support at the initial design stage of the project.

  • As contemporary society becomes information-oriented, major construction companies have recently invested in information management, but small and medium ones have not. Though the small and medium companies recognize the information management is necessary and important, they don't have an ability to possess technical expertises. The purpose of this study is to develop a Schedule Risk Control System based on blogs using IT and web technologies for construction managers in small and medium construction companies. The system makes a chance to identify risk factors and prepare for responses to settle risks happened in preconstruction phases, and enables the managers and headquarters to predict and handle schedule risks by sharing information about risks on the blogs.

  • In China, the enhancement of water services has become the most crucial issue confronted with the rapid urbanization and industrialization process. A huge financial gap to meet the demand for water infrastructure and need for adopting advanced operation technology precipitated the rapid growth of PPP over the last 10 years. Diverse schemes of PPP such as TOT, Divestiture, and Management Contract and Lease have been practiced. Local governments and private investors/operator have adjusted their objectives and strategies to avoid potential pitfalls behind BOT projects in China. However, current academic research outcomes do not properly reflect important issues of BOT projects or related case studies in China. This limitation has brought in the lack of assessment of important risks and success factors required for the improvement of the body of risk management. In this regard, this study uses the market analysis method to identify major schemes of PPP water projects and conducts case studies on five PPP projects to identify key risk and success factors in association with each different scheme. It is expected that the risk and success factors identified from the cases will be used as reference to Korean companies which plan to enter the Chinese water market.

  • The current remodeling cost estimation process is not only dependent on the historical data of new building construction, but it also has a poor linkage with risk-based estimation approach. As such, there is a high risk of falling short of initial budget. To overcome this, a risk-based estimation approach is necessary by providing a probabilistic estimation in consideration of the potential risk factors in conducting the remodeling projects. In addition, the decision-making process should be linked with the risk-based estimation results in stead of intuitive and/or experience-based estimation. This study provides a probabilistic estimation process for residential remodeling projects by developing a detailed methodology in which a step-by-step approach can be achieved. The new proposed estimation approach can help in decision-making for remodeling projects in terms of whether to proceed or not, by effectively reflecting the potential risk factors in the early stage of the project. In addition, the study can enhance the reliability of the estimation results by developing a sustainable estimation process model where a risk-based evaluation can be accomplished by setting up the cost-risk relationship database structure.

  • The main roots of CM service contracts include existing customer repurchases and those made by new customers by existing ones. The study on customers and loyalty can be factors to strengthen CM's competitiveness. However, there have been little attempt to study customer satisfaction and customer loyalty. Construction Management (CM), the advanced construction management method, was introduced 15 years ago in the mid 1990's in the domestic market. The aim of this research is to build a model that can predict customer loyalty based on how much customers are satisfied with CM service. To measure customer satisfaction and loyalty, this research surveyed 135 decision-makers who have experienced CM services. Customer satisfaction was tested and analyzed according to different phases: planning, designing, procurement, construction, and post construction. Referral intention was tested based on NPS theory. Customer types were divided into detractors, passively satisfied and promoters according to the tested measurement and multinomial logistic regression between the satisfaction by construction phases and customer types. This research resulted to a model that can predict customer types: detractors, passively satisfied and promoters, which were determined according to satisfaction level. The initial planning phase also revealed which factor is most influential for a customer to become promoter. These results can be used to acquire customer loyalty by managing the satisfaction of customers through a project under an Internet-based environment. Such can provide the needed information in quickly exploring positive and negative word-of-mouth feedbacks.

  • Recently, a few major construction companies in Korea have a growing interests to the risk management system, and they are trying to apply it to their construction projects. However, the existing methodologies to be applied to the foreign public projects are not proper to the construction environments due to its adaptabilities, that has one time process and heavily depends on personal judgement. The purpose of this paper is to propose a risk response process in consideration of the residual risks, which would be more adaptable and practical in the construction environment, overcoming the current obstacles to be mentioned above. This process has systematic repeat process until the residual risks go down to the risk thresholds based on the efficiency of specific response strategy.

  • 러시아와 한국간의 공식적인 접촉은 1990년 6월 샌프란시스코에서 개최된 정상회담이다. 동년 9월 뉴욕에서 개최된 양국의 외무장관 회담에서 러시아와 한국의 외교관계가 수립되었다. 그간 양국간에는 협정을 통한 협력의 법적기반이 조성되었는데 주요 분야를 보면 무역, 투자보장, 어업, 이중과세방지, 군사기술분야, 원자력의 평화적 이용, 문화교류에 관한 협정들이 있다. 역시 양국간의 주요 관심사항은 무역과 경제협력 분야이다. 2007년도 러시아와 한국의 무역액은 150억 달러를 초과함으로써 전년도에 비해 55.5% 증가하였다. 러시아의 한국으로의 수출은 약 70억 달러로서 전년도에 비해 52.6% 증가했고 한국으로부터의 수입은 80억 달러를 초과함으로써 전년도에 비해 56.1% 증가하였다. 그리하여 러시아는 한국의 10대 교역국으로 성장하였다. 가스와 오일 프로젝트 추진과 관련하여 사할린지역에서 사용하기 위해 한국으로부터 수입하는 드릴기계장비, 탱커, 자동차, 휴대전화는 한국과 러시아 양국간 경제성장의 주요요인이 되고 있다. 2008년 1/4 분기 양국간 무역액은 42억 달러를 초과했는데 이는 전년도 동기와 비교해서 72.1% 증가한 것이다. 이 중 한국에의 수출은 17억 달러를 초과했는데 이는 전년도 1/4분기에 비해 91.7% 성장한 것이다. 한국으로부터의 수입은 약 25억 달러로서 전년도 1/4 분기와 대비해서 60.6% 성장했다. 러시아와 한국간의 경제교류가 크게 증대하게 된 배경에는 러-한경제과학기술협력공동위원회가 큰 역할을 담당했다. 이 논문에서 필자는 무역과 투자측면에서 본 양국간 경제협력의 특징을 고찰하는 한편 러시아의 동부지역(러시아 극동 및 바이칼횡단지역)과 한국과의 협력과 관련된 역동성과 과제를 제시하는데 연구의 목적을 두었다. 한국은 외국기업과 함께 러시아 극동지역의 무역과 경제협력 증진에 상당한 공헌을 함으로써 러시아 극동경제권에서 주요 무역파트너가 되고 있다. 또한 본 연구에서는 한국과 러시아간의 주요 협력프로젝트에 관하여 고찰하는 한편 앞으로의 전망을 제시하였다. 이 문제는 무엇보다도 한-러간의 공동 에너지프로젝트 및 에너지자원의 무역과 관련되어 있다. 한국과 러시아는 이미 많은 분야에서 상당한 정도로 상호 협력관계를 발전시켜왔다. 여기에는 정책, 에너지, 경제, 문화, 과학기술 분야가 포함되어 있다. 현재 러시아와 한국간에는 에너지 분야에서의 전략적 대화채널 구축에 관한 문제와 함께 연료 및 에너지공단 건설과 관련하여 협력문제가 논의되고 있다. 에너지 분야에서의 전략적 대화개념 구축을 위해서는 전략, 예측 및 투자환경의 문제가 양국간에 집중논의 되어야 하고 법제상의 조화문제도 논의되어야 한다.
