This research targeted discussions on re-utilization of Korean creative economic innovation center. It is meaningless to simply discuss its re-organization. The focus of this study was to find a way that transforms it into totally new one. The study followed several steps. First, it delineated criteria from existing literature for comparing creative eco-system of Silicon valley, Kyoto eco-system and eco-system based on Korean creative economic innovation center. Second, it compared the three eco-systems in details. Third, it discussed a direction for transforming eco-system based on Korean creative economic innovation center. It was suggested that the Kyoto eco-system can be a role model. It was also suggested that governmental role should be changed from controller to facilitatior which stimulates regulation relaxations and helps to establish market formation.

The purpose of this study was to investigate the effects of lime fertilization and light intensity on beech regeneration strategy in a mature beech forest(ca. 150 years old) gaps, which was located in the soiling areas Germany, where the soil is an acid brown earth. For the experiment canopy gaps of 30m diameter were cut, and one canopy gap remained as untreated while the other was limed(3t dolomite h $a^{-1}$). Soil chemistry, soil water potential, light intensity(PAR), ground vegetation, beech seedlings and mycorrhiza were investigated along transect from the stands into gaps to the north. The results of this study are followings: 1) In the limed gap, soil chemistry was greatly improved and a vigorous herb layer developed as compared to the unlimed gap. 2) Development and growth of the beech seedlings in the unlimed gap were generally deficient. Specially, developments of lateral roots were very lack. 3) Through the lime fertilization, the minerals contents of beech leaves such as calcium(Ca) and magnesium(Mg) were increased, while manganese(Mn) was decreased. There was antagonism between potassium(K) and calcium(Ca) or magnesium(Mg). 4) The relative mycorrhiza frequency(RM) in beech seedlings of the southern edge was very higher than that of the middle part, and through the lime fertilization extension of the species Laccaria amethystina appeared clearly. The results of this study showed that lime fertilize in forest, where the soil is acid, will be necessary..

Based on the case study methods, the study analyzes that the countless UCC Cloud cloud is the niche creation by the lead users make process. This research show as follows. First, The Drama lovers and fan fiction writers are not only drama consumers but UCC creators/producers. By the process that the UCC and fan fiction is tailored to meet the needs of their users create fan fiction in fandom community, they create an entirely different niche from original drama. Second, the flow(drama consumption/evaluation, viewers needs/adaption, the user's creation/production) which community's creative users make sequentially coevolutes with the flow(drama information offer, intentionally supply/diffusion, derivatives production) of media companies. Third, the drama fandom community activities which is non-commercial activities form the drama ecosystem with a new paradigm, as well as form a virtuous cycle inked to the market continuously beyond fun, play, empathy.

본 논문은 북제주군 협제리 해안가 근처에 소재한 건지굴을 대상으로 화산지역의 용암동굴에서 특이하게 진행되고 있는 용암석회질화 현상에 대하여 동굴내부와 주변 상황에 근거한 분석과 고찰을 통하여 석회질화의 발생 원인을 규명하는데 기여하고자 하였으며, 특히 동굴내부의 생태계와 연관된 분석을 병행 시도하였다. 용암동굴(화산동굴)은 생성이후 퇴화한다. 그러나 용암동굴에서 용암석회질화(lava-calcification) 현상이 발생하면 용암의 기공과 균열부분 또는 용암석간의 틈새에 석회질 성분이 지하수에 녹아 침투하여 고화되면서 구조적 보강효과가 발생하여 견고하게 진행된다. 이러한 현상은 마치 콘크리트 건축구조물에서 구조재료들을 물리적으로 연결하여 결합시키는 시멘트의 역할과 같으며, 따라서 용암동굴의 경우, 동굴이 형성된 이후에 전반적으로 퇴화가 진행된다고 알려진 일반적 경향에 반하여 용암석회질화 현상에 의해 오히려 구조적 보강현상이 이루어지고, 용암석회질화 현상이 진행될수록 용암동굴의 일반적 경향으로 나타나는 동굴퇴화현상 보다는 구조적 견고함의 진행성을 나타내는 특이현상을 갖는다. 이와 같은 진행성 용암석회질화 현상이 북제주군 협제리에 소재한 건지굴에서 진행되고 있음이 국내에서 최초로 확인되었다.

The purpose of this study is to discuss new entrants' role in a business ecosystem and to analyze growth strategies of a new entrant in the movie industry. When participants of a business ecosystem complement one another with their own unique capabilities, they can coevolve and develop the business ecosystem. Especially, new entrants armed with competitive advantages are the key success factor for improving robustness of business ecosystem. Korean movie industry is dominated by a few large enterprises and thereby threatening fair trade. In an effort to encourage new entrants in the industry, this study analyzed success factors of a film distributor, Next Entertainment World(NEW). The success factors include unique criteria in selecting scenarios, quality management, rapid decision making process, and competent management team. Implications for the results and the future study are discussed.

The olfactory organ of a Korean endemic species, Pseudobagrus koreanus, was investigated to describe its morphology and histology and analyze correlation between habitat environment and its ecological habits and characters, using a stereo microscope, a light microscope, and a scanning electron microscope. Its external morphology showed tubular anterior nostril at the tip of the snout and slit posterior nostril at the base of the nasal barbel. The olfactory chamber showed the rosette structure consisting of numerous lamellae radial and parallel to the medium raphe. The olfactory lamella has the sensory epithelium with olfactory receptor nuerons, supporting cells, basal cells, lymphatic cells, plasma cells and the non-sensory epithelium with stratified epithelial cells, mucous cells, lymphatic cells. In particular, 1) 41~43 (n=20) lamellae, 2) lymphatic cells and plasma cells, 3) mucous cells including neutral polysaccharid may be olfactory characteristics relevant to a stagnant or a standing habitat environment, nocturnal habit dependent on olfaction, and taxonomic characters compared at least to other catfish species.

The purpose of this research is to evaluate an accurate biotope area ratio model with efficiency and convenience of database management through promoting sustainable development to provide people amenities in a new town. In particular, the biotope area ratio is used not only in the environment impact assessment but Green building certification criteria. But now there is no any index map of biotope. So it is very hard to implement with data for supplement results. In this research, we suggest the model of integrated attributable information. The evaluation of biotope area ratio is to include a basic land use planning map and a building coverage area which is a wall of greening surface and roof. In case of non building coverage area, the evaluation of biotope area ratio is to include water space, artificial ground, natural ground and pervious gap-pave. A weighted value on the spatial information is combined into the information. And then the merged one is given a land use planning information in a block. In the weighted value on the space type information, it is possible to in its circumstances. Therefore, it can be substituted a correspondence of numerical change for various values elastically in this model.

This study aims to classify the biotope types based on the vegetation community in built-up areas by different land use and to map the plant communities. By classifying biotopes according to a taxonomic system, the characteristics of a biological community can be well-represented. The biotope classification indexes for the target area include human behavioral factors such as land use intensity, land-use patterns and land-cover types. The type classification was divided into four hierarchic ranks starting with Biotope Class, next by Biotope Group and Biotope Type and lastly by Biotope Sub-Type. The Biotope Class was first divided into two areas: the areas improved by humans and the areas unimproved by humans. The improved areas were again divided into permeable and non-permeable regions on the Biotope Group level. In the Biotope Type level, permeable paving areas were divided into areas with wide gap pavers and those with narrow gap pavers. The differential species of each biotope type are Lindera glauca, Conyza canadensis, Mazus pumilus, Vicia tetrasperma, Crepidiastrum sonchifolium, Zoysis japonica, Potentilla supina and Festuca arundinacea. The results of this study suggest that the biotope classification methodology, using a subjective phytosociological approach, is a useful and valuable tool and the results also suggest the possibility of applying more objective and scientific methods in mapping and classifying various environments.

The Indie Game market is emerging as a niche for game startups. We analyzed policy cases related to indie games in local governments, and the private sector to suggest ways to improve the Indie Game market. As a result, the problems of Indie Game-related policies resulted in lack of market research and success case analysis, lack of manpower training program, accelerator program, and public-private cooperation project. To build an Indie Game ecosystem, we proposed the necessity of establishing an effective promotion system through cooperation between the local government and the state.
