The present study grasped the operation characteristics and operation management of forest museums in Korea and analyzed satisfaction with the foregoing. In the results of a survey of forest museums' operation characteristics, with regard to groups to which exhibits were helpful, over half of respondents answered that the exhibits were helpful to students and many respondents had an opinion that all age groups should be equally considered as targets of exhibition. Among matters that were considered with regards to forest museums, accessibility showed the highest rate of answers followed by museum programs. The curator was needed for the majority of respondents were exhibits prior to the survey had the highest expectations for the medium. With regard to the operation management of forest museums, the expected value of periodic and extraordinary exhibitions was shown to be high and high and satisfaction was shown by the professionalism of staff. As for matters of forest museums that must be improved, attention should be paid to the development of programs in which users can participate, diverse exhibition media should be developed, and exhibition should be planned to fit the composition of exhibits. As for operation management, since exhibits were repeated every year, environments should be changed by exhibiting new exhibits or otherwise and active methods of improvement should be devised such as the utilization of broadcasting media for public relations.

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.

Current Korean innovation system is facing a new turning point while the growth-oriented and S&T provide-oriented development strategy. Accordingly, there are needs for not only system transition in various area, such as sustainable energy, agriculture, and rural area but also STI policy paradigm shift to create a new innovative pathway. Living lab is being discussed in European country as a new innovative model based on user participation and as a niche experiments for sustainable system transition. This study attempts to analyze the living lab cases which are for the purpose of energy transition, agriculture rural areas system transition, and STI policy paradigm shift. Based on this analysis, the implications were derived in Korea. European Suslab project, C@R project, and Taiwan living lab, promoted diverse transitional experiments successfully by collecting users' background and experiences from pre-planning stage and by maintaining the user-driven innovative actions within the whole development process. This result provides various suggestions to current Korean situation that central government and local governments are considering the introduction of living lab. Living lab can also be utilized as a strategic niche experiments for socio-technical system transition in region or country, as a mean of policy integration, and as a new regional innovation model. In addition, it can be an important platform to realize the policy integration reflecting the user and demand-side which are highlighted in recent innovative policy paradigm.

DNA 컴퓨팅은 분자 수준(molecular level)에서 연산을 수행한다. 따라서 일반적인 실리콘 기반의 컴퓨터에서와는 달리, 순차적인 연산 제어를 보장하기 어렵다는 특징이 있다. 그러나 DNA 컴퓨팅은 화학반응에 기초한 연산이기 때문에, 실험자가 의도한 연산을 많은 수의 분자에 동시에 적용할 수 있으므로 실리콘 기반의 컴퓨터와는 비교할 수 없는 병렬 연산을 구현할 수 있다. 병렬 연산을 구현하고자 할 때, 일반적으로 연산에 사용하는 모든 DNA 분자들을 대상으로 연산을 구현할 수도 있다. 그러나 전체가 아닌 일부의 분자들을 상대로 연산을 수행하는 것 역시 가능하며 이 때 자연스러운 방법으로 사용할 수 있는 방법이 배깅(Bagging)이나 부스팅(Boosting)과 같은 앙상블(ensemble) 계열의 학습 방법이다. 일반적인 부스팅과 달리 가중치를 부여하는 것이 아니라 특정 학습자(learner)를 나타내는 분자들을 증폭한다면 가중치를 분자의 양으로 표현하는 것이 가능하므로 분자 수준에서 앙상블 계열의 학습을 구현하는 것이 가능하다. 본 논문에서는 앙상블 계열의 학습 방법 중 특히 부스팅의 효과를 DNA 컴퓨팅에 응용하고자 할 때, 어떤 방법이 가능하며, 표현 과정에서 고려해야 할 사항은 어떠한 것들이 있는지 고려하고자 한다. 본 논문에서는 규모를 사전에 한정할 수 없는 진화 가능한 그래프 구조(evolutionary graph structure)를 학습할 수 있는 방법을 찾아보고자 한다. 진화 가능한 그래프 구조는 기존의 DNA 컴퓨팅 방법으로는 학습할 수 없는 문제이다. 그러나 조합 가능한 수를 사전에 정의할 수 없기 때문에 분자의 수에 상관없이 동일한 연산 시간에 문제를 해결할 수 있는 DNA 컴퓨팅의 장정을 가장 잘 발휘할 수 있는 문제이기도 하다.개별 태스크의 특성에 따른 성능 조절과 태스크의 변화에 따른 빠른 반응을 자랑으로 한다. 본 논문에선 TIB 알고리즘을 리눅스 커널에 구현하여 성능을 평가하였고 그 결과 리눅스에서 사용되는 기존 인터벌 기반의 알고리즘들에 비해 좋은 전력 절감 효과를 얻을 수 있었다.과는 한식 외식업체들이 고객들의 재구매 의도를 높이기 위해서는 한식 외식업체의 서비스요인, 식음료요인, 이벤트 요인 등을 강화함으로써 전반적인 종사원 서비스 품질과 식음료품질을 높이는 전략을 취해야 한다는 것을 시사해주고 있다. 본 연구는 대구 경북소재 한식 외식업체만을 대상으로 하여 연구를 실시하여 연구의 일반화와 한식 외식업체를 이용하는 이용 고객들이 한식 외식업체를 재방문하는 재구매 의도가 발생하는데 있어 발생하는 과정을 설명하는 종단적 연구를 실시하지 못한 한계점을 가지고 있다.아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자인 기술개발 및 디자인 교육지원의 강화를 통하여 각각 디자인 경쟁력$\righta

Establishment of efficient cooperative ecosystem of research institutes is important for the efficiency of national innovation system, especially in the era of technology convergence. Performance of institutes inside the ecosystem is dependent on the position of the institutes in the system. This study investigates the relationship between network structure and research performance, and determines significant factors on the research performance. The results of 5 year panel data analysis of SCI journal papers of Korean government research institutes indicate that four network centralities -degree, betweenness, closeness, and eigenvector- and structural holes have significant effect on the research performance of the institutes. Among the four centralities, closeness and eigenvectors are more significant than others. Implications of the results of this study for policy of establishing efficient cooperative system are that increasing the cooperative activities of less active institutes is more effective for research performance than increasing the magnitude of cooperative activities of all institutes. Also, when an institute starts a new cooperative relationship, it is better to have relationship with an active institute first.

우리나라의 경우 1조원 이상 피해를 입힌 자연재해가 '98년 이후 집중적으로 발생하는 등 최근 급격한 도시화 산업화 및 범지구적인 이상기후 현상으로 자연재해로 인한 피해가 점차 대형화 다양화되는 추세이다. 그에 따른 국내 재해관리 및 사전예방의 중요성은 그 동안 여러 차례 기획사업 및 재정계획을 통해 제시된 바 있으나, 대부분 추진계획 수립에 그치고 실질적인 예산 편성시에는 충분히 반연되지 못한 실정이다. 따라서 본 연구에서는 우리나라의 재해예방투자사업의 규모와 구체적 계획에 대하여 살펴보고자 한다. 재해사전예방 분야의 기존 투자계획으로는 "제1차 국가안전관리 5개년 기본계획"과 "2005-2009 국가재정운용계획", "수해방지대책 백서" 등이 있었으며 그 중 "제1차 국가안전관리 5개년 기본계획"은 정부역사상 처음으로 시행하는 중 장기 국가재난관리정책으로, 풍수해대책, 설해대책 등의 자연재해를 비롯하여 총 17개의 재난유형별 재난관리대책을 포괄하고 있으며, 11개 부처 및 시도에 대해 27개 사업, 36조 8천억원을 투자하는 계획을 제시하였다. 가장 최근에는 2010년 8월에 국무총리실 주도 재난관리 개선 민관합동 TF팀을 구성하여 기후변화 및 기상이변에 선제적 대응 및 기존 방재체계에 대한 근본 패러다임 전환을 통한 선진적 방재시스템 구축을 추진하기 위하여 기후변화대응 재난관리 개선 종합대책을 마련하였다. 일선 경험이 많은 민간전문가 주도로 철저히 현장 중심의 문제점과 대안을 검토하고 대책을 준비함으로서 기존의 재난관리대책 구축방법과 차별성을 띄었다고 할 수 있다. 이번 재난관리 개선 종합대책에서는 5개 시 도의 현장조사와 기존대책을 분석하고, 전문가 의견 등을 검토하여 도시유역종합치수계획, 소하천 및 사방댐 정비, 소규모 시설 정비 등 26건을 포함한 '99년부터 3회에 걸쳐 추진한 재해관련 범정부 종합대책을 검토하여 필요성이 있으나 추진이 미흡했던 과제는 포함시켰다. 또한 기후변화 대응에 필요한 신규과제 및 재해취약요인이 드러난 도시방재를 위한 개선과제를 집중 검토하도록 하였다. 다수부처 관련 쟁점과제에 대해서는 주관부처를 정하거나 민간 전문가가 참여하는 조정회의 및 세미나, 공청회를 통해 보완 검토하였다. 그 결과로서 2011년 전년대비 재해예방 관련 사업에 대한 국고 투자규모는 도시침수방지 17%, 수자원 관리 25%, 항만 정비 17%, 산사태 예방 24%, 농업기반시설 정비 20%, 위험지 정비 19%, 재난 예측 및 대응시스템 개선 16% 증가하여 투자계획이 수립되었으며 전체적으로는 약 21% 증가된 투자계획이 수립되었다.

Users who want to experience the metaverse for tourism are exposed to strategic planning in space for the purpose of cultural content. In addition, users learn integrated cultural content in the process of proceeding according to the virtual environment. and Along with the meaning of time and space, users will experience space-telling. It is important to induce interest from the beginning of the experience to continue the experience. However, obstacles arise in this process. This is because developers should promote connections with new information to users who do not have sufficient prior knowledge and only have keywords of interest. Therefore, efficient design methods to enhance interest should be studied in advance. But so far, there has been no research on how to systematically design prior organizers to induce interest in virtual space. This study is an interest-inducing design method that occurs in the process of developing the meaning of virtual space and storytelling of cultural content, and can be seen as a basic study using conceptual guidance-based prior organizer education and learning techniques. First, virtual space elements and human behavior theories were considered. Subsequently, five representative examples of previous organizers currently used were explored, and redesigned and proposed based on a conceptual map for information access and delivery purposes. Through this research process, it was possible to confirm that spatial attributes and cognitive interest elements were effectively transmitted to meaningful learning leading to storytelling learning and elements of service design design method through conceptual guidance.

Public construction projects are implemented by government or public agencies using public resources to enhance the welfare of the people. Therefore, this paper investigates the impact factors for public construction performance. Then, the weights for impact factors are assigned using AHP. The impact factors are categorized into construction policies, project management efforts, and project environment. Further, 16 detail impact factors are listed in each category. The results show that weights are ordered in appropriate budget, reasonable project implementation process, and pre-project planning. These impact factors are related with pre-construction management activities. However, construction related impact like procurement, work difficulty, and construction environment show relatively low weights. The results can be useful to improve construction performance with managing impact factors showed high weights.

Recently, the convergence of genre-mixed collaboration and technology-mixed collaboration in performance art strategically fuses different goals and different properties, satisfying anticipated demand, and developing into experimental forms that bring out convergence contents of new value. To supplement problems of convergence attempts and heighten levels of completion, the effective collaborative processes of media experts must be studied and improved. This thesis attempts to study effective collaborative production plans of convergence performance that correspond to the demands of the times through multimedia convergence performance prototypes(Live performance play + Pre-made digital animation). It categorizes performance production processes into pre-production and production and researches the effective collaborative production processes of convergence performances that utilize these two forms of media through work selection, production direction establishment, human resource constituents, production schedule plan establishment, visualization processes, and performance practices and rehearsals. Continuous research must be conducted based on convergence performance contents planning, changes in production methods, and an understanding of distinct characteristics among convergence contents for the industrial development systemization and vitalization of convergence contents to be made possible.

Demand forecasting is essential in establishing national and corporate strategy as well as the management of their resource. We forecast demand for multi-generation product using discrete choice model combining diffusion model The discrete choice model generally captures consumers'valuation of the product's qualify in the framework of a cross-sectional analysis. We incorporate diffusion effects into a discrete choice model in order to capture the dynamics of demand for multi-generation products. As an empirical application, we forecast demand for worldwide DRAM (dynamic random access memory) and each of its generations from 1999 to 2005. In so doing, we use the method of 'Technological Forecasting'for DRAM Density and Price of the generations based on the Moore's law and learning by doing, respectively. Since we perform our analysis at the market level, we adopt the inversion routine in using the discrete choice model and find that our model performs well in explaining the current market situation, and also in forecasting new product diffusion in multi-generation product markets.
