Biodiversity is a key element of ecosystem of which function provides essential product and service in human life. In the course since development projects often causes damages to biodiversity, environmental impact assessment technique must be capable of accurately assessing potential impact from flora and fauna and to entire ecosystem. Korea needs improvement of its assessment technique that is compatible with Korean environmental regulatory standard that is generally stricter than that of most countries. This study attempts to explore both domestic and overseas biodiversity assessment techniques and analyze each stage of environmental impact assessment. The data is collected from numbers of literatures selected by navigating both domestic and overseas literature database with certain keywords. Among the 44 selected papers, overseas publications outnumber those of domestics, and there are more researches on assessment methodology of biodiversity than assessment tool and model. In terms of environmental impact assessment, the number of papers on environmental impact forecast exceeds the numbers of papers on current state of environment and the impact minimizing solution. Therefore, contents and trends of those researches in the different stages of environmental impact assessment discussed in this paper not only suggest potential impact on biodiversity and minimization solutions in detail, but is also a valuable resource particularly for biodiversity relevant environmental assessment technique improvement in Korea. Proposing of a new direction of improvement in biodiversity assessment techniques makes this study significant, and further research for preservation of biodiversity should follow up to provide an improvement scheme for biodiversity assessment techniques in the future.

The number of users of SNS such as Twitter and Facebook increases due to the development of internet and the spread of supply of mobile devices such as smart phone. Moreover, there are also an increasing number of content pollution problems that pollute SNS by posting a product advertisement, defamatory comment and adult contents, and so on. This paper proposes an improved method of extracting the feature of content polluter for detecting a content polluter in SNS. In particular, this paper presents a method of extracting the feature of content polluter on the basis of incremental approach that considers only increment in data, not batch processing system of entire data in order to efficiently extract the feature value of new user data at the stage of predicting and classifying a content polluter. And it comparatively assesses whether the proposed method maintains classification accuracy and improves time efficiency in comparison with batch processing method through experiment.

Gangneung Danoje does not only have the longest history but also is the largest folk festival in Korea. However, during its long history Gangneung Danoje has not always been the way as it is today. As records reveal, since the Chosun dynasty and through Japanese rule, it has gone through numerous variations and registration processes in order to become a national designated major intangible cultural asset. Especially after it has been appointed as a national major intangible cultural asset Gangneung Danoje has under gone through variety of transformations. First of the few changes is the citizen-lead characteristic. As Gangneung Cultulral Center took charge of Danoje this trait has become prominent. Hereby Chosun dynasty's government lead system has transformed into a civilian lead festival. Second alteration is the enormous scale of expansion and the variations of the characteristic of the festival because of it. Dano event has increased annually from 12 events in 1974 to 58 events by 1999. As the scale of Danoje enlarged the promoters found solutions by providing diversified events in order to satisfy peoples' various aspirations from the festival. However this solution lead to a diversion - from participating festival to a spectating festival. And the last change that occurred is the awareness of the need to develop Danoje into an international festival. This is rather a desire from the government than of the people. In 1994, Korea visiting year as an opportunity this consciousness grew active. For instance, the invitation of mass foreign folk performance in 1999 seems to conform to this policy. The intention to make Gangneung Danoje not only to represent Gangneung but also to represent Korea's folk event can be witnessed. As we enter 21st Century this inclination for international festival has strengthened. Gangneung government has shown enthusiasm to find the future of Danoje by inviting external service corps to assess Danoje. The current inclination appears to be increase its value as an international festival through UNESCO cultural property registration and having this as a foundation make Danoje become an international cultural tourist product. The judgment of this will be made after Gangneung International Folklore Festival 2004.

Recently, with the development of technologies for the fourth industrial revolution, convergence and complex technology are being applied to aircraft, electronic home appliances and mobile devices, and the number of parts used is increasing. Increasing the number of parts and the application of convergence technologies such as HW (hardware) and SW (software) are increasing the No Defect Found (NDF) phenomenon in which the defect is not reproduced or the cause of the defect cannot be identified in the subsequent investigation systems after the discovery of the defect in the product. The NDF phenomenon is a major problem when dealing with complex technical systems, and its consequences may be manifested in decreased safety and dependability and increased life cycle costs. Until now, NDF-related prior studies have been mainly focused on the NDF cost estimation, the cause and impact analysis of NDF in qualitative terms. And there have been no specific methodologies or examples of a working-level perspective to reduce NDF. The purpose of this study is to present a practical methodology for reducing NDF phenomena through data mining methods using quantitative data accumulated in the enterprise. In this study, we performed a cluster analysis using market defects and design-related variables of mobile devices. And then, by analyzing the characteristics of groups with high NDF ratios, we presented improvement directions in terms of design and after service policies. This is significant in solving NDF problems from a practical perspective in the company.
