After reformation of 'the law of private investment on social infrastructure' on January 2005, BTL of educational facilities can improve the education circumstance at early stage, however there are trial and error, problems of execution as well. The key of this problem is not only related to whether BTL project is more reasonable, but it also leads to the proper performance of eligibility analysis on BTL. Therefore, it lead to the proper carryout of eligibility analysis on BTL. In order to promote effective BTL project of educational facilities, this study analyzes problems of existing model and creates the evaluation model for solving this problem. In this study, the evaluation model of investment on BTL has more quick ,accuracy and useful effect than previous one, if it is applied on eligibility stage. Moreover, this method could be applied to public building, SOC facilities effectively based on being modified as each characteristics of structure suitably.

As energy industry is undergoing a rapid structural changes, economic feasibility analysis based on the conventional discounted cash flow (DCF) method has limitations to incorporate management's flexibilities. We present a real options pricing method (ROPM) which can be applied to an energy sector as an alternative. In order to examine the usefulness of ROPM, this study compares the result of DCF method applied to the investment of cogeneration power plant with that based on the ROPM incorporating the value of real of options inherent in the project. The simulation results show that the value of investment opportunities improves using ROPM compared to that with the conventional DCF methods. Therefore, a specific project which appears to be unprofitable from the conventional point of view could be, actually, an economically feasible one based on ROPM method, when properly incorporating the management's flexibilities inherent in the project.

This study examined the effects of cultural factors and demographic factors on the perceived appropriateness and likelihood of using five categories of inappropriate negotiation strategies. Five categories of inappropriate negotiation strategies consist of traditional competitive bargaining, attacking opponent's network, false promises, misrepresentation of information and inappropriate information gathering. Two kinds of cultural variables, Hofstede's cultural dimensions and 'Chemyon' dimensions were used as universal, etic variables versus indigenous, emic variables. Survey result shows age and gender had significant effects only for traditional competitive bargaining, but gender and personal negotiation style did not have any effects for the inappropriate strategies. Hofstede's dimensions as well as Chemyon dimensions had significant effect for perceived inappropriateness and likelihood of using inappropriate strategies. While both Chemyon and Hofstede's dimensions were significant, Chemyon accounted for more variance than Hofstede dimensions in most cases. This suggests Chemyon's vital role in explaining Korean negotiators' perception and attitude towards inappropriate negotiation strategies. Implications of the results and future research are discussed.

This study attempts to investigate effects of service conveniences on perceived value and customer voluntary behavioral intention in family restaurants. We categorized service conveniences in five dimensions (i.e, decision, access, transaction, benefit, and post-benefit). We considered perceived value as having three parts, namely functional, emotional, and social. We also specified three segments of customer voluntary behavioral intention as participation, cooperation, and loyalty. The results showed that service conveniences such as transaction convenience, post-benefit convenience, and benefit convenience have an influence on functional value as a perceived value, but no effect from decision convenience and acceptability[this is a new variable to me]. In addition, access and benefit conveniences affect social value. When it comes to the effects of perceived value on customer voluntary behavioral intention, social value was found to affect participation and loyalty, while functional value appeared to influence cooperation.

The choice of appropriate methodologies has always been a challenge. It is time to find obstacles when Extreme programming(XP) is adopted. In this paper, we invest status of adoption of XP methodology which is more popularized. We survey how the Values and the Practices of XP can be adopted to developer in terms of the usefulness and the easy of use of XP. As a result, it is regarded as a successful one in improving quality and timeliness through software development process. The Values and Practices, a basis of XP philosophy and its adoption, could be easily accomplished, but other elements - communication, feedback. collective ownership, pair programming, simple design and customer participation - which do not depend on technology could not be accomplished easily. To introduce XP easily in the creative and labor intensive software development fields, the managers and the educators have to make efforts to apply these Values and Practices based on humane characteristics as well as technical elements.

This study is to suggest a new method of analyzing personality types of characters in narrative. First, we examined the history of the taxonomy of character types that existed in narrative theories so far. Until now, the classification of character types in narrative theory consisted largely of a formal classification based on roles in narrative, a content classification based on human internal qualities, and a complementary classification in which the two classification criteria are united. The problem with the existing character classification type is difficult to categorize it in spite of the usefulness of the content classification based on human internal qualities. On the other hand, the classification based on the role of the character in the narrative does not help as much as a practical analysis methodology because the classification is formal. In this study, we try to solve this problem by introducing Shalom Schwartz's human value type, and to make human character's value type and human role correlated with each other as a new character analysis methodology. Schwartz's study of value type is a very effective method to grasp the motivation of human behavior, and it seems to be very meaningful in analyzing the directivity of characters.

Unlike existing social platforms that seek openness, an audio-based social platform is characterized by its limitations. This study uses the Value-Based Acceptance Model(VAM) to analyze the role that such limitations play in the user's acceptance of audio-based social media. In this study, restrictive properties are defined as access-limitation, communication-limitation, and content-limitation. This study aims to analyze the effect of each variable on the perceived value and usage of audio-based social media. The hypothesis test was conducted based on the survey responses total of 207 users and potential users. The results was analyzed that three limiting variables affect perceived benefit factors, usefulness and playfulness, and the user's acceptance intention. This study is significant in that it presents a model based on the VAM and provides guidance for new forms of social media growth.

Measuring the intangible asset has been vigorously studied for its importance. Especially, the value of character in media industry is difficult to quantitatively evaluate in spite of the industry's rapid growth. Recently, the Social Network Analysis (i.e., SNA) has been actively applied to understand human usage patterns in a media field. By using SNA methodology, this study attempts to investigate how the character network characteristics of media works are linked to human search behaviors. Our analysis reveals the positive correlation and causality between character network centralities and character search data. This result implies that the character network can be used as a clue for the valuation of character assets.

본 학술기사의 목적은 구조설계를 위한 강력하고도 유용한 도구로서의 최적화기법을 소개하는 것이고 현재의 기술현황을 보여주는 것이다. 최적화의 발전은 유한요소법과 컴퓨터기법 그리고 최적화알고리즘 및 소프트웨어의 동시적인 발전으로부터 이루어진다. 이렇게 됨으로써 사용자가 꼭 최적화 이론가가 될 필요성은 없어질 것이고 모든 공학자는 설계의 질과 생산성을 증진시키기 위해 최적화를 훌륭한 설계기술로서 이용할 수가 있게 될 것이다. 최적화를 위한 두가지 접근방안이 제안되었다. 하나는 최적화 과정중 직접적으로 사용되는 민감도 정보를 제공하기 위해 유한요소해석 프로그램을 수정하는 것이고, 다른 하나는 설계변수와 구조응답들로 구성된 목적함수, 제약조건으로된 최적화문제에 최적화기법을 연결하는 것이다. 가장 좋은 방법은 이 두 접근방법의 조합된 방법인 것 같지만 서로 모순된 것 같기 때문에 분명하지가 않다. 따라서 이 부분은 앞으로 주목을 받을 충분한 가치가 있는 내용이 될 것이다. 원료 부족에 대한 인식의 증대와 부존에너지자원의 빠른 고갈은 경량이면서 효율적이고 경제적인 구조물에 대한 욕구를 증폭시켰다. 따라서 오늘날의 유용하고, 거대한 계산능력을 고려한다면, 최적화기법을 사용하고자 하는 동기는 충분한 것이고 숙련된 공학설계자들에 의해 응용됨으로써 최적화는 경쟁적인 우위를 제공하는 강력한 도구가 될 수 있을 것이다.

선박에서 AIS 탑재가 확대는 해상에서의 전산 시스템 기술 발전에 큰 영향을 미치고 있다. AIS는 VTS가 선박의 식별, 트랙킹, 모니터링과 같은 일반적으로 알려진 기능을 제공하는 것뿐만 아니라 해상 교통 연구, 통계 분석, 학술 연구에 유용한 실시간 정보를 제공하기도 한다. 그러나 AIS 관측 자료의 신속한 축적은 이루어지고 있지만 VTS 플랫폼 측면에서 선박 위치 자료를 수집하고 분석하는데 한계가 있다. 이러한 관점에서 본 연구는 데이터 마이닝 기술과 GIS기술을 적용하여 AIS 자료를 분석하고자 한다. 이것은 해상 교통 관리 분야에 GIS 분석, 데이터베이스 관리 체계, 데이터 웨어하우징, 데이터 마이닝과 같은 잠재된 가치 정보를 도출하는 기술과 통합하는 시도이다. 현재 몇가지 제약사항이 있지만, 향후 VTS 관제 업무에 유용한 자원을 제공하는 새로운 방안이 될 것이다.
