With rapid technological and market change, new product development (NPD) complexity is a significant issue that organizations continually face in their development projects. There are numerous factors, which cause development projects to become increasingly costly & complex. A product is more likely to be successfully developed and marketed when the complexity inherent in NPD projects is clearly understood and carefully managed. Based upon the previous studies, this study examines the nature and importance of complexity in developing new products and then identifies several issues in managing complexity. Issues considered include: definition of complexity : consequences of complexity; and methods for managing complexity in NPD projects. To achieve high performance in managing complexity in development projects, these issues need to be addressed, for example: A. Complexity inherent in NPD projects is multi-faceted and multidimensional. What factors need to be considered in defining and/or measuring complexity in a development project? For example, is it sufficient if complexity is defined only from a technological perspective, or is it more desirable to consider the entire array of complexity sources which NPD teams with different functions (e.g., marketing, R&D, manufacturing, etc.) face in the development process? Moreover, is it sufficient if complexity is measured only once during a development project, or is it more effective and useful to trace complexity changes over the entire development life cycle? B. Complexity inherent in a project can have negative as well as positive influences on NPD performance. Thus, which complexity impacts are usually considered negative and which are positive? Project complexity also can affect the entire organization. Any complexity could be better assessed in broader and longer perspective. What are some ways in which the long-term impact of complexity on an organization can be assessed and managed? C. Based upon previous studies, several approaches for managing complexity are derived. What are the weaknesses & strengths of each approach? Is there a desirable hierarchy or order among these approaches when more than one approach is used? Are there differences in the outcomes according to industry and product types (incremental or radical)? Answers to these and other questions can help organizations effectively manage the complexity inherent in most development projects. Complexity is worthy of additional attention from researchers and practitioners alike. Large-scale empirical investigations, jointly conducted by researchers and practitioners, will help gain useful insights into understanding and managing complexity. Those organizations that can accurately identify, assess, and manage the complexity inherent in projects are likely to gain important competitive advantages.

This paper examined the settlement and evolution of the Namdo Food Festival holding in Nakan folk village since 1994. The Namdo Food Festival is a representative event tourism in Chonnam which beautifully displays Nakan eup-sung's folk landscape and Namdo's traditional food, a prime tourist resource. Since 1994, the Namdo Food Festival has steadily evoloved in the scale aspects of the program budget, and the number of visitors participating in festiva. In addition, the period of the food festival was fixed for a week, early in October. The majority of visitors to the festival was from Kwangju. Moreover, visitors from other provinces have steadily increased, in particular visitors from Yeongnam province such as Pusas and Kyeongnam provinces have increased since 1996. In order to settle down and develop the Namdo Food Festival, the followings should be done change of the ownership from public to private sector, training of professional entertainers, development of programs which can reinforce historical aspects and placeness of Nakan folk village, adoption of management technoques for the local economic activities, and extension of linkage with tourists places around Nakan folk village, reflection of tourists interests and needs through a continuoua tourist's behaviour analysis.

Industry-University cooperation for pioneering overseas market contributes to improve the quality of manpower and the export performance. However, performance is showing that without exporting experience, exploring overseas market is not promising. Without systematic training and preparation, pioneering overseas market can be a waste of time and budget. I have conducted interviews with 30 participants in Industry-University cooperation for pioneering overseas market. As a result, I have derived a model for each phase of Industry-University cooperation. 8 stages of this model are student selection, cooperation company networking, student education, overseas market research, selection of trade fair, preparation of trade fair, dispatch of trade fair and follow-up management. Opinions of experts have been reflected and compiled to each suggested stage. Specific details can be applied directly to those affiliated who want to start the first or foremost pioneering overseas markets.

Monitoring of groundwater Quality is essential for the preservation of groundwater resources. In practice. however, groundwater monitoring network is designed based on the experience and intuition of experts or on the convenience. This study proposes a simulation-optimization approach for the optimal design of monitoring networks. In it, the predicted three-dimensional concentration data are used as the input of an optimization problem. Various design objectives and constraints are considered and the problem is formulatcu as the 0-1 integer programming. The methodology was applied to a sanitary landfill site. The results show that the monitoring network configuration changes as the monitoring goal, operation time and constraints vary. The proposed method turns out to be an efficient tool for the wide range of groundwater Quality monitoring network design problems.oblems.

Frequent design changes or unnecessary project executions due to illogical practice, lack of feasibility study and, hasty drive have raised problems of budget waste in Korean construction projects. Since the MOCT (Ministry of Construction & Transportation) published Master Plan for budget efficiency for government projects, there have been a lot of policy efforts for budget saving. However, it has been pointed out that cost management at the pre-construction phase, which greatly influences the cost still remains imperfect. The target cost for government clients is not being estimated reasonably, and cost controlling at the pre-construction phase is not yet being carried out properly for keeping the budget. Therefore, improved construction cost management at the pre-construction phase was proposed in this paper. The cost management systems of advanced countries were investigated for it, and the issues were drawn from the cost management systems of these countries. On the basis of the issues, the present conditions and problems of domestic construction cost management at the pre-construction phase were analyzed for suggestion.

Recently, companies seek a way to overcome their financial crisis by reducing costs in the field of IT. In such a circumstance, cloud computing is rapidly emerging as an optimal solution to the crisis. Even in a digital forensic investigation, whether users of an investigated system have used a cloud service is a very important factor in selecting additional investigated subjects. When a user has used cloud services, such as Daum Cloud and Google Docs, it is possible to connect to the could service from a remote place by acquiring the user's log-in information. In such a case, evidence data should be collected from the remote place for an efficient digital forensic investigation, and it is needed to conduct research on the collection and analysis of data from various kinds of cloud services. Thus, this study suggested a digital forensic framework considering cloud environments by investigating collection and analysis techniques for each cloud service.

Serials subscription prices continue to escalate but university library budgets of those have not grown concurrently at the same rate. In fact, library budgets of serials subscription have decreased as a percentage of total library expenditure. Also titles with little or no use should be cancelled to make room for new serials that might be needed to reflect new research interests or changes in curriculum. This study includes overview of the serials cancellation and substitute solutions for subscriptions in university library. Taking into account costs and coverages, availability of cancelled serials through interlibrary loan is high in general. There is a potential for considerable savings by providing access to low-use titles, and that is a combination of commercial document delivery and pay per view based on e-business could be a viable alternative to subscription in many cases.

The growing socio-economic effect caused by science and technology requires public to participate in policy-making process, which makes government to boost public understanding of science(PUS). Government has also exerted to construct infra for PUS. However results are not so meaningful. The government-funded science museum has mainly provided the program for students. Besides, science broadcasting channel has recorded the worst viewing rate. Meanwhile, some of the private sector-manufactured contents have attracted public attention in recent years, which is realized by considering elements such as an interesting topic selection, use of outside experts, two-way communication system, level adjusting for public through flexible running system. This study analyze podcast based program, face to face lectures, display contents by private industry, fab lab etc. on the base of the reciprocal PUS model to sort out the reason they have successful results. Futhermore, it argues that government should intensify support for private sector and create synergy effect by cultivate collaboration system between government and private sector to enhance the efficiency of PUS and offers public policy to realize the plan.

Data Envelopment Analysis(DEA) model is a linear programing based technique for measuring the relative performance of organizational units where the presence of multiple inputs and outputs makes comparison difficult. DEA model allows each unit to adopt a set of weight that shows it in the most favorable light in comparison to the other units. The purpose of this study was to evaluate the performance of the libraries of national university in terms of relative efficiency, measured by the method of DEA. Twenty six libraries of national universities in Korea were used to analyze. The number of employees, size of library, budget, and number of books were used for input data, and the number of visitors, number of loan books, and number of books for lending and borrowing were used for output data. We found out that number of libraries with 100% relative efficiency among 26 libraries from 2005 to 2007 were only 9, 9 and 10, respectively. Moreover most of the libraries need to increase outputs and decrease inputs in order to improve efficiency.
