Watermelons, Citrullus species(Cucurbitaceae), are native to Africa and have been cultivated since ancient times. T he fruit flesh of wild watermelon is watery, but typically hard-textured, pale-colored and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well colored flesh, have a narrow genetic base, suggesting that they are originated from a series of selection events in a single ancestral population. In this study, considered as sweet dissert watermelon, genetic resources, C. lanatus, comprising of traditional cultivars and local accessions were collected from 18 different countries in four continents. A total of 60 accessions were characterized morphologically according to RDA genebank descriptors combined with Japan and China, list for 11 qualitative characteristics, leaf length, leaf width, petiole length, petiole diameter-source, stalk end length, stalk diameter, fruit length, fruit diameter, rind thickness, flesh sugar content($^{\circ}brix$), fruit weight-sink, and 6 sink related characters, leaf margin incision-source, fruit shape, fruit skin ground color, fruit skin stain color, fruit skin stain pattern and flesh color-sink, were also investigated. Even though the relatedness between some morphological traits and fruit weight or fruit sweetness showed no significance, the accessions investigated have a great deal of variation for most of the morphological traits. Additionally, the accessions which showed good performance in flesh color and fruit shape (IT271048) and high sugar content of flesh (IT274119, IT290118) above 14brix, were investigated in this experiment. The accessions, which have the information on specific traits including the selected accessions could be introduced, distributed and investigated for further use.

The number of multi-cultural members, such as immigrant labors, international marriage women are gradually increasing in Japan society. Now it might be said that Japan has become a multi-cultural society. Recently in Japanese kindergartens and nursery schools the numbers of foreign and bi-cultural children are increasing. The aim of this paper is to review the researches on the cultural diversity in the Japan, especially in childcare. Methodology proceeds from a review of related literature to internet-based data and to the statistics issued by the government. Through reviewing them, the problems of teachers' assumptions and the importance of discussions about teachers' competencies to educate minority children and to communicate with their parents were suggested. As a switch over to multi-cultural society is occurring in Japan, the attitude of assimilationism is weakening, and the local community is now beginning to tolerate the multi-cultural childcare. Consequently, It was over to age that is distinguish identity from only nationality.

This study was carried out with an objective to prepare the framework of conformity for the 21st century modern fashion, which is interactive with mankind, based on a position that the 21st century contemporary fashion with its amalgamating trend of diversified artistic forms may not be elucidated on a standpoint centering on one certain modality. The hybrid fashion trend of historical modality which provides freedom and satisfaction in creation of an individuals expressive power in expressing true desire of mans inside through man-centered thought of the times has made multifarious motives of the past and present fragmentary. It thus extracts inner divisions and the concept of consolidation through three-dimensional form. Modern fashion is newly interpreted by the material and details of high technologies. and is harmonized by mix and match with various expressions. By having it, it is being expressed together with many types of dresses and ornaments. Modern fashion is being expressed together with many types of dresses and ornaments by new interpretations with the material and details of high technologies and by being harmonized with mix and match with various expressions. The hybrid fashion design trend of regional elements formed by stimuli and contacts of diverse local culture by globalization of network that was achieved by scientific technologies of the contemporary information society has disintegrated varied boundaries in the conventional culture by the latest communication technology-new media on the basis of newly created culture. The fact that regional elements could be expressed as if they were interrelated without each being deprived of originality may be explained with an interpretation on pluralism. The hybrid fashion design trend of cultural aspect, which manifests in the background of scientific technological culture as it transcends the societal-cultural boundaries based on the de-centralization theory of Frederic Jameson, has supplemented the imperfect meanings through conversional correlation with other forms and internal program changes. The middle stratal and polyhedral characteristics are seen as each cultural element is dismantled and reassembled by application of 'multiple-time point expression'. Design forming method is not to bring destruction from outside, but to embrace instability and chaos through radical dismantling of the inside. and to pursue diversity and openness. Thus. it is implemented by an approach that takes the role of design process. In communication of discontinuity, continuity was dismantled through forms of mixing, overlap, perversion, insertion and coincidence.

This study was done to develop indicators for cities that can be used in the long term and in a sustainable manner. Activation indicators were developed to improve the resilience in the downtown area of Seo-gu, Incheon. Preliminary indicators were derived from prior studies on similar indicators of resilience for urban regeneration, and an expert opinion survey was conducted to analyze the suitability and importance of the indicators. Activation indicators were established for improving urban resilience in six areas: population stability, social inclusion, industrial diversity, local productivity, environmental sustainability, and social-based convenience. From 60 preliminary indicators, 42 indicators were selected through the expert opinion surveys for securing an economically active population, establishing a living infrastructure, improving the settlement environment, and upgrading industry to reflect the characteristics of the West, including industrial complexes. It was found that diversification is necessary. Further study is still necessary to improve the objectivity of the indicators and calculate a resilience index. The significance of this study is that it looks at quantitative indicators, complements other studies on regional decline diagnosis, and presents realistic alternatives suitable for domestic situations based on the concept of resilience.

In this thesis we have examined the concrete forms and periodic tendency changes of eup-settlements, local administrative town, locations within 91 districts in 71 counties of Gyeongsang province. First of all, we have analyzed the overall conditions of eup-settlement locations in Joseon Dynasty under the criterion of topography, feng-shui, and scenery image of the mountains at the back. Then we looked into alterations of location forms mainly of the eup-settlement in which the exact time of migration can be identified and cities which have the evident dates of construction. To sum up, the result is as follows. Firstly, the concrete form of eup-settlement locations in Joseon Dynasty are usually built up in traditional ways, however, quite a few unconventional ones also existed. Secondly, the town castles constructed at the end of Goryeo Dynasty period and before 1430's are hardly related to the traditional location format of Joseon Dynasty, yet the ones constructed after 1430's were mostly in the typical location format. Thirdly, the old eup-settlements established before 1425 are scarcely in the typical location form of Joseon dynasty, but the new eup-settlement established after 1425 were mostly in the typical location forms.

The purpose of this study is to explore the suitable creative class in korea as the core capital of creative urban growth under creative economy era. We are test to find it for two types of creative class. One is Richard Florida(2002)'s creative class, the other is Mcgranahan & Wojan(2007)'s recasting creative class. Data on 2010 for this paper are generated from Statistics Korea. As a result, we find that the economic geography of creative class is highly concentrated. Furthermore, the geography of creative class is strongly associated with innovation index and high-technology industry location. And Mcgranahan & Wojan(2007)'s creative class is more strong relationship between all dependent variables than Florida's. We also find that it has better power of explanation than Florida's with all of them in regression analysis. According to the results, this study suggests some solutions. First, this study can be provided to government and local policy makers as basis data and practical policy guide to attract creative class. Second, this paper presents standard about a diversity of definitions for creative class in Korea. Third, this research also facilitates follow-up studies about regional economic growth and creative climates.

This study analyzed the spatial change of urban green spaces in Daegu from 1989 to 2009 using cell based spatial metrics. To do so, the conversion process of land covers during the past 20 years was explored using a land cover change detection matrix. The synoptic analysis with a moving window sampling strategy was conducted to quantify cell based spatial metrics related to size, shape, cohesion, and diversity and to explain the spatial change at the local level. Difference maps were then generated by subtracting the 1989 maps of spatial metrics from the 1998 maps and the 1998 maps from the 2009 maps. The gradient analysis was performed to identify the directional change of spatial metrics along an urban development axis in Daegu. The results from this study show that urban green spaces in Daegu during the past 20 years have been gradually fragmented around the new town housing development districts such as Dalseong-gun, Seongseo, and Ansim. Forests were most prominently fragmented in the Hwawon area while most rapidly in the Chilgok area. Grasslands were largely fragmented in many areas due to the decrease in size and cohesion indices and most fragmented in the Ansim area. The spatial pattern of the decreased and fragmented urban green spaces identified by this study can be used as a base data for establishing the environment-friendly urban development strategy in Daegu.

The aim of this article is to analyze the relationship between the change of the diversity of the industrial structure, and regional employmentability and the intensification of regional competitiveness, and consequently, is to present policy implications. As a result of the analysis of the whole industry such as the primary, secondary and tertiary industry in Chungnam Province, the existing strategic implementation on the employmentability and regional competitiveness throughout the policy on the existing specialized industries can be regarded as appropriate. However, under the condition that danger and stability in each industry are fluctuated and the internal and external circumstances are varied, the detailed analysis and rapid policy prescription on the primary and tertiary industry are required. Along with these results, policy implications are as follows; Firstly, in terms of effectiveness, regional policy are simultaneously conducted along with industrial, technological and regional development's policies while consider ing complex and comprehensive characteristics of the regional industry and rapid changing the global market conditions. Secondly, with respect to equity, regional policy is needed to implement by reducing the socio-economic gap across regions and mixing regional and sectoral policies along with regional and local uniqueness.

We reviewed and compared nationwide surveys conducted in advanced countries (i.e., Japan, Germany, USA, and UK) with those in Korea, including the third Nationwide Survey of Natural Environments, which began in 2006 and will proceed until 2010. Based on this comparative analysis, we suggest alternatives to the nationwide survey of natural environments that are suited to Korea. Given the focus on species abundances and distributions in previous nationwide surveys in Korea, surveys of habitats, ecosystems, and ecoregions are required to more effectively protect biological resources in Korea. Furthermore, their spatial distributions should be mapped using periodical satellite images and aerial photographs. In particular, satellite images can be used to survey species, habitats, and ecosystems. Natural resources monitoring and management specialists are needed to collect various data and improve survey results. The participation of community volunteers is also important to develop an awareness in local residents of natural environment conservation. Independent survey institute (i.e., a 'National Ecosystem Institute') should be established to develop a database and survey scheme for species, habitats, and ecosystems throughout Korea. Moreover, the survey institute could develop natural environmental policy through the data analysis to meet the objectives of the Convention on Biological Diversity. The establishment of a survey institute will allow the completion of a natural environment survey that considers various factors, including physical habitat conditions. This will allow us to detect subtle changes in species abundance and spatial distributions and provide accurate and timely information on natural environments.

Spatio-temporal variation in fruit set in orchids would affect long-term population viability and will influence genetic diversity over many generations. The aim of this study was to examine the breeding system of the nectariferous terrestrial orchid Epipactis thunbergii, to specifically determine levels of fruit set in terms of time and space under natural conditions. We examined pollination under natural conditions and conducted hand pollination experiments during a 2-year survey in four populations located along 1.5 km of coastal line in Jinguiri (rual village) [Jeollanam-do (province), southern Korea]. We found that, over a 2-year period, levels of percentage of fruit set were similar within patches of the four populations. By contrast, we detected significant differences in the percentage of fruit set among patches. We also found that plants with larger inflorescence size produced significantly more fruits than plants with fewer flowers. Over a 2-year period, the percentage of fruit set for E. thunbergii was similar but low (14.1%) compared to that averaged for eighty-four rewarding species (37.1%). However, an increase in fruit set was achieved by hand-pollinations: artificial self-pollination (90.5-95.2%), artificial geitonogamy (94.7-95.0%), and cross-pollination (artificial xenogamy, 91.3-91.4%). No emasculated flowers produced fruits and no automatic pollination was found in E. thunbergii. Our findings suggest that E. thunbergii is a self-compatible terrestrial orchid that depends on pollinators (insects) to achieve fruit set in natural habitats, and that local environmental conditions were similar over a period of 2 years in the study area. Our results also highlight the cryptic variation of fruit production in time, but more pronounced variability in space.
