The purpose of this study is to evaluate the creation techniques of artificial wetland, one of biotopes developed to promote biodiversity in urban areas, and to look for improvement steps. Specifically, artificial wetland creation techniques were categorized into living environment and living creature classification. Being living conditions for creations, habitat environment was reviewed with a focus on water and soil environments. Living creatures were classified into plants, insects, fish, and birds. The evaluation of creation techniques was done in post-construction evaluation while considering the creation of habitats for living creatures. Intervention by users, changes in living environment and living species, and relevance of creation techniques were reviewed. Key results of this study are as follows. (1) Water environment for the living environment of creatures provides a suitable environment conditions for the living of creatures through a process easing the use of piped water. Various water depths and embankment appear to have a positive impact on the living of aquatic life. In particular, embankment covered in soil naturally played an important role as a place for the activities of aquatic insects and young fish as well as the growth of aquatic plants. (2) Various aquatic and ground plants to promote insect-diversity, shallow water, and old-tree logs had contributed greatly in increasing the types and number of insects. Aquatic insects. Aquatic insects were seen much particularly in areas where aquatic plants are rich but water is shallow than any other areas. (3) A space piled with stone to provide habitats for fish was not much used. However, it was observed that fish used embankment built with natural stones and embankment using logs in areas where water is deep. In addition, it was confirmed that 1,500 fish that had been released propagated using various depths and places for birth. (4) It was analyzed that techniques (creation of island, log setting, and creation of man-made bird nests) to provide habitats and to attract birds are not serving their roles. In such a case, it is believed that species had not increased due to the smallness as well as isolated features of the area. Based on theoretical review, they are judged to be areas that are likely to be used when a greater variety of birds is introduced. It is judged that attracting and keeping more birds at the site, such spaces need to be linked systematically in the future in terms of building eco-network while ensuring an adequate living areas. (5) In the study areas, users intervened greatly. As a result, a blockage was created preventing the normal growth of plants and non-indigenous plants were introduced. In order to limit the intervention by users, setting enough buffer zones, and environment education programs were urgently required. D/H=1>Hyangkyo> houses on the river>temples>lecture halls.

The microinjection of retroviral vectors into the perivitelline spaces of MII-stage oocytes increased production of transgenic bovine embryos. However, oocytes have various sizes of perivitelline space, and there is the tendency that the oocyte membranes are damageable by micropipettes during the injection of retroviral vectors into perivitelline spaces or oocytes. Thus, it was not always possible to stably inject retroviral vector into perivitelline spaces of oocytes. Here we used sucrose to minimize the damage of the oocyte membrane. When the oocytes were suspended in 0.5% sucrose, poor quality oocytes showed rough cytoplasmic membranes, while good quality oocytes maintained smooth membranes. However, when the tatters were subjected to in vitro fertilization, no significant differences were observed in cleavage rates (82% of control Vs. 84% of sucrose treated oocytes). The Same trends were obtained from the oocytes fertilized after microinjection of LN$\beta$-EGFP and LNC-hGH genes into the perivitelline spares. The rates of cleavage and blastocyst from microinjection of LN$\beta$-EGFP genes were 81 and 25%, and from microinjection of LNC-hGM genes were 53 and 30%, respectively. The result indicated that microinjected oocytes could develop to the blastocyst stages after in vitro fertilization with no significant difference from control group. Moreover, the integration of hGH-gene (by PCR analysis) was detected in 52% of infected cleaved embryos and the expression of EGFP-gene (under a fluoresrence microscope) was also observed in 34% of infected blastocyst. These results indicated that 0.5% sucrose treatment could be an efficient method not only to select good quality embryos but also to inject retroviral vectors into perivitelline spares without any harm and hence improving developmental rates.

This study says that giving a life through the mixed power of motions which can not be fixed. It is a fundamental activity of the art of dance. In the fact, the art of dance is defined as the most instinctive and intuitive arts show that dance is a harmony of emotion on the body, thus, this view wants to discuss the relations between "sense and body". This view doesn't focus on the mere motions of dancing form, but characterizes dance as an art of another vitality through the mixture and combination of these motions. In other words, this study emphasizes that dance transcends time and space on stages, and that dance, as an expression of identity, is an art which shows a sense from inside of human. Therefore, when we want to understand the true meaning of the art of dance, we should attend what attributes of dance define it as an art and show its creative. This study, thus, seeing those attributes as the life-giving function of dance, aims to help understand the principle meaning of the art of dance that realizes creation as well as the attitudes of audience who appreciate the art of dance. And by doing so, this study contemplates how we should see the creative idea of choreography, forming sympathy and the art of dance.

The purpose of this study was to establish unified standards on the scope of protection of choreographic works and to suggest methods for the protection of choreography copyright. 20 experts was selected among dance experts or copyright experts and depth interview method, Delphi method and AHP analysis were used. The result was summarized as follows : First, 50 percents of the experts thought pure dance works and popular dance works should be protected by same standard, while 45 percents of the experts suggested different standard. Second, 55 percents of the experts claimed required fixation on certain medium, while 40 percents did not claim required fixation but only expression. Requirement of originality was to independently create choreography and to reflect creative characteristic(65%). 70 percents of experts were positive on defining dance choreography as independent work, while 25 percents were negative. Elements of the choreography protection scope were in following order of importance: pattern of movement, creative and concrete plot, combination of movements and steps, and movement pattern with specific space. Third, methods for the protection of dance copyright in hierarchical classification were in following order of importance : 'copyright education', 'activation of organization of dance copyright trust management', 'choreography registration' and 'inducement of social concern. Fourth, 'Active participation of dance copyright trust management organization' was thought as the most important development plan. 'Improvement of dancers' awareness of copyright', 'inducement of choreography registration', and 'reinforcement of copyright education' followed in order.

This study is a basic study to develop standards and foundations for the establishment of traditional Korean gardens and aims to understand the current status of their components and expression methods and identify problems by investigating Korean gardens developed overseas. Nine sites were selected for field surveys and monitoring assessments. The results suggest: Overall, there is a lack of popular generality and temporal characteristics among these gardens, as they are mere reproductions of historical elements. There have also been errors of traditional and experimental interpretations. In terms of design aspects, traditional gardens are primarily compilations of landscape elements and certain ornamental features. In terms of landscape, they tend to be insufficient in parlaying appropriate spatial scales and experiential hierarchies; they also lack considerations of the context of neighbouring landscapes. In terms of guidance and information delivery, there is a worldwide lack, in general, of recognition of Korean gardens, given the broad variety of names attached to them; therefore, name standardization is recommended. In terms of development, management, and use, it is essential that designers suggest plant types, as well as alternatives, that match the characteristics of a given space; a receptive attitude vis-$\grave{a}$-vis the characteristics of their use is required.

In this study, scenarios based on the leakage of highly compressed air and fire occurrence turned out to be high risks in an operation stage of CAES facility were constructed and estimated. By combining Bernoulli equation with momentum equation, an expression to calculate an impact force of a jet flow of compressed air was derived. An impact force was found to be proportional to the square of diameter of fracture and the pressure of compressed air. Four types of fire scenarios were composed to evaluate an effects that seasonal change and location of fire source have on the spread behavior of smoke. Smoke from the fire ignited in the vicinity of CAES opening descended more quickly below the limit line of breathing than one from the fire occurred 10 m away from CAES opening, which is expected to occur due to a propagation of wave front of smoke. It was shown that a rate of smoke spread of the winter fire is faster than one of the summer fire and smoke from the winter fire spreads farther than one of the summer fire, which are dependent on the direction of air flow into access opening. Evacuation simulation indicated that the required safe evacuation time(RSET) of the summer and winter fires are 262, 670 s each.

Objective : This animal model aimed to compare the rat group that received brain irradiation and did not receive additional treatment (only saline) and the rat group that underwent brain irradiation and received Granulocyte colony stimulating factor (G-CSF) treatment. In addition, the effects of G-CSF on brain functions were examined by magnetic resonance (MR) imaging and histopathologically. Methods : This study used 24 female Wistar albino rats. Drug administration (saline or G-CSF) was started at the beginning of the study and continued for 15 days after whole-brain radiotherapy (WBRT). WBRT was given on day 7 of the start of the study. At the end of 15 days, the behavioral tests, including the three-chamber sociability test, open field test, and passive avoidance learning test, were done. After the behavioral test, the animals performed the MR spectroscopy procedure. At the end of the study, cervical dislocation was applied to all animals. Results : G-CSF treatment positively affected the results of the three-chamber sociability test, open-space test and passive avoidance learning test, cornu Ammonis (CA) 1, CA3, and Purkinje neuron counts, and the brain levels of brain-derived neurotrophic factor and postsynaptic density protein-95. However, G-CSF treatment reduced the glial fibrillary acidic protein immunostaining index and brain levels of malondialdehyde, tumor necrosis factor-alpha, nuclear factor kappa-B, and lactate. In addition, on MR spectroscopy, G-CSF had a reversible effect on brain lactate levels. Conclusion : In this first designed brain irradiation animal model, which evaluated G-CSF effects, we observed that G-CSF had reparative, neuroprotective and anti-neurodegenerative effects and had increased neurotrophic factor expression, neuronal counts, and morphology changes. In addition, G-CSF had a proven lactate-lowering effect in MR spectroscopy and brain materials.

This study investigated the muscular dystrophin levels in freely moving Australian cattle mainly fed grass, freely moving Korean cattle fed mainly a grain diet, and Korean cattle fed a grain diet but housed in a relatively limited space of a cow house. The total skeletal muscle specimens of 244 cattle were collected and immediately fixed in 10% neutral formalin. The same area was biopsied from the cattle in both countries. The findings showed that fatty infiltration is highly correlated with membrane-associated protein degradation in skeletal muscle, and that among several membrane-associated proteins, dystrophin showed the most significant reduction in expression in the cattle with fatty infiltration. Similarly, CD36 was more highly expressed in the cattle with fatty infiltration of skeletal muscle. Various breeding factors, such as oxidative stress; the presence of oxidized lipids in the diet; and environmental factors such as exercise, temperature and amount of time spent, may have critical effects on the degradation of normal cytoskeleton proteins, which are required for maintaining normal skeletal muscle architecture. Among the sarcolemma membrane-associated proteins, dystrophin is the most sensitive membrane protein that is involved muscular dystrophy and muscular degeneration. Thus, the present findings may be useful for studies on muscular dystrophy in humans or the pathogenesis of muscular diseases in animal models.

This study examined how the tradition and culture based on the historical experience of the region are regenerated on the making regional identity and symbolic representation in Kurim-ri, Youngam. Kurim has represented the most typical community of the aristocratic class through Daedong-gae of 400 years. But, since 1970's Kurim has undergone a rapid change in regional identity in Kurim ; from the beginning of the spot of Wangin festival to the village of earthenware, the village of pottery culture heritage most recently. The process of history-making around Wangin in Kurim was connected with the strategy of the pottery culture village-making centering around the Youngam Pottery Culture Center. These projects ultimately were resulted in expression the regional identity, 'Kurim of Wang-in'. The regional tradition of Daedong-gae and Wangin in Kurim was linked together solidly through the Wangin festival procedures. And the excavation of a kiln site in Kurim which was going on with the process of history-making at the same time around Wangin in Kurim provided the cultural episode on related 'earthenware' with an archeological foundation. As a consequence of these, the cultural space, the Young-am Pottery Culture Center has came to establish in Kurim finally. However, recently the Kurim of Wangin and Daedong-gae which was representative of regional identity in Kurim is bringing Dosun who was distorted and estranged during the history-making focused on Wangin in Kurim. Now, there are some cultural issues in Kurim ; an authentical settlement of the Youngam Pottery Culture Center in Kurim and how Wangin and Dosun is linked together into the cultural strategy of 'the traditional village, Kurim'.

In this study, we introduce a design of Fuzzy RBFNNs-based digit recognition system using the incremental-PCA in order to recognize the handwritten digits. The Principal Component Analysis (PCA) is a widely-adopted dimensional reduction algorithm, but it needs high computing overhead for feature extraction in case of using high dimensional images or a large amount of training data. To alleviate such problem, the incremental-PCA is proposed for the computationally efficient processing as well as the incremental learning of high dimensional data in the feature extraction stage. The architecture of Fuzzy Radial Basis Function Neural Networks (RBFNN) consists of three functional modules such as condition, conclusion, and inference part. In the condition part, the input space is partitioned with the use of fuzzy clustering realized by means of the Fuzzy C-Means (FCM) algorithm. Also, it is used instead of gaussian function to consider the characteristic of input data. In the conclusion part, connection weights are used as the extended diverse types in polynomial expression such as constant, linear, quadratic and modified quadratic. Experimental results conducted on the benchmarking MNIST handwritten digit database demonstrate the effectiveness and efficiency of the proposed digit recognition system when compared with other studies.
