In order to evaluate the role of macrophytes as refuge of zooplankton on physical distribution (i.e. summer rainfall), we investigated the environmental factors, macrophytes, and zooplankton in waterside zones (macrophytes zones) and open water zones of 17 wetlands from May and August, 2011. In this study, a total of 51 zooplankton species were identified, and Polyarthra sp. and Diaphanosoma brachyurum were found to be the most dominant species. Waterside area of each wetland were occupied by a total of 10 macrophyte species, species composition and biomass (dry weight) were different in the survey sites. Zooplankton was more abundant in waterside zone than open water zones lacking macrophytes (One-way ANOVA, df=2, F=27.1, P<0.05), in particular, waterside zone of 1, 8, 9, 10, and 11 wetland were supported by high zooplankton density after summer rainfall. This wetlands were developed by various macrophyte species than other wetland, and submerged plant commonly presented. Waterside zones with various macrophyte species provides complexity to the habitat structure, should be utilized as refuge to avoid disturbance such as summer rainfall. The results indicate that macrophytes are the key components to enhance bio-diversity include zooplankton, and the inclusion of diverse plant species in wetland construction or restoration schemes will result in ecologically healthy food webs.

This study was performed to evaluate the effectiveness of biological critical control points using the genetic profile of Escherichia coli isolates from pork cutting plants. Samples were collected from carcasses, equipment (knife, table, glove, transport belt, boning and skinning machine), the environment (wall and floor), and meat cuts during the cutting process from two plants. Pulsed-field gel electrophoresis (PFGE) was used to characterize the E. coli isolates. An identical genotype was detected from the carcasses, equipment, environment, and final meat cuts, and showed that the incoming carcasses, which were contaminated during transportation from slaughterhouses, were a major source of E. coli that was spread throughout processing. Also, consistent cross-contamination due to improper cleaning and disinfection procedures was another possibility. As a result, incoming carcasses and cleaning procedures should be considered critical control points in pork cutting plants, since a heating step is not used to inactivate microorganisms. Furthermore, the high rate (59.6%) of E. coli isolation indicates E. coli can be a good indicator in livestock processing plants even though it has genetic diversity.

The objective of this study was to monitor vegetation development process after timber harvesting at (Mt.) Baekwoonsan Seoul National University Forests, Korea. Two monitoring plots were established in 1994 and woody plant were monitored from 1994 to 1999. Vegetation development pattern during last six years(1994-1999) after timber harvesting were as follows; Styrax obassia, Styrax japonica and Lindera erythrocarpa as of the existing tree were competitive species in the first year after clearcut, and Styrax japonica and Lindera erythrocarpa as of sprout tree) and Aralia elata as of seedling were dominant species in the sixth years after clearcut. Species diversity indices of harvested forest interior was decreased at the southwestern slope and increased at the northeastern slope. According to DBH distribution pattern, No. of individuals of Lindera erythrocarpa and Aralia elata showed vigorous growth in the sub-canopy layer and then Styrax japonica, Quercus serrata, Maackia amurensis, Lespedeza maximowixzii, Lindera obtusiloba, Staphylea bumalda, Clero-dendrum trichotomum, Weigela subsessilis, in order showed good growth in the sixth year after clearcut. Lindera erythrocarpa with a reversed J-shaped curve pattern by DBH class will be increased while Aralia elata with a J-shaped curve pattern will be decreased.

In the modern society in which globalization and localization proceed simultaneously, diversified and rapid migration of diaspora makes a new from of boundary off the frame of the state and the nation. This new border accompanies cultural change and racial mixture; retains ethnic conflict, the gap between rich and poor, alienation and discrimination, as well as power conflict; and extends its influence. Nowadays, the countries all over the world including Korea face problem of Diaspora in numerous forms. And each country takes an approach to the problem of the diaspora in the aspects of their society, culture and political technology. This implies that most countries, without understanding the new form of border which is alive and dynamic, define and conceptualize the diaspora in the frame of one state and one nation to carry forward the policies accordingly, resulting in inequal, incomplete and awkward homogenization. This study aimed to explore the identity of the diaspora, the core for the problem solving. Of course, studies about the identity of the diaspora have been continued until today and many great outcomes have been achieved. Nevertheless, this study aimed to explore the identity of the diaspora and the national policies which have a close interrelationship with it. It is because the study ultimately aimed to highlight the interrelationship between the destination countries, Russia and China, and the diaspora, through the definition and the classification of Russian diaspora and Chinese diaspora and the analysis of the national policies about that. However, the intention was not to distinguish superiority through the comparison of the polices about the diaspora between two countries, but to focus on the diversity of the identity of the diaspora through defining each different diaspora and paralleling the policies. Second, the reason for looking into the diaspora policies of these two countries is because it is judged the changes in the diaspora policies of each country is one of the active factors for the changes in the identify of the diaspora of each country and it is the basic research for the study on the identity of the diaspora. New migration of diaspora changes the identity of the state, and the state makes the policies and enforce the policies, resulting in the influence on the diaspora. This interaction acts as the growth factor for the new boundary. The causes of Russian diaspora and Chinese diaspora show apparent 'differences'. In parallel with this, the policies about the diaspora in Russia and China arouse 'differences' to the diaspora. The variation of the identity of the diaspora made by these differences will suggest other viewpoints on the diaspora, and these viewpoints will become the foundation for solving the problem of the diaspora in the present times.

This paper pay attention to silent puppets which appear in the traditional puppet performance. Not only movement of silent puppets which are involved with expression of body of the mime, but also various methods overcome limits of the silent are studied in this paper. Through the study of performance method and historic unfolding aspects, I confirm two main points. First point is that overcome limits of the silent, through the diversity of performance aspects. Second point is that silent puppets have been existed since the early stage of history, and show typical unfolding aspects on their way. Combining two main points, We can say that silent puppets go through continuous unfolding aspects on their way and have meaning of existence. The meaning of existence are that silent puppets seek deviant desire which deviate from everyday life and transcendental desire which seek a freedom through an imagination or an idea. It is interesting that the reasons of existence are associated with the emphasis of necessity which is encouragement of audience's desire and imagination that are necessary of accomplish of mime. After all, silent puppets say that diverse attempts which overcome limits of the silent are accomplished with the performance aspects and historic unfolding aspects, and through that sought unusual communication. Through the performance methods and signification aspects, silent puppets say that diverse groping for which maximize of audience's imagination, stimulation of imagination for audience's spontaneousness, and diverse groping for audience mind performance have been performanced as well. I think that those are the voice of silent puppets for activity of mime in the korea.

Recently, as cultural projects are being carried out in various ways, the interest in the space where culture and arts can be provided is also increasing. Therefore, this study selected and analyzed F1963 in Busan. The purpose of this study is to examine the effects of brand asset factors of brand image, brand awareness, brand asset awareness, and loyalty on customer satisfaction and community development of brand asset in complex cultural space and to examine whether customer satisfaction has a mediating effect on the relationship between brand asset in complex cultural space and community development. As a result of the analysis, brand asset of complex cultural space had a positive effect on the satisfaction of users. Also, brand asset of complex cultural space has a positive effect on community development. The satisfaction that users get from the complex cultural space has a mediating effect on the influence of brand asset of the complex cultural space itself on the community development. The implications of this study suggest that complex cultural space plays an important role in the region, and it is necessary for local communities and local governments to brand complex cultural space through diversity of cultural and artistic activities.

This study focuses on analyzing the key success factors of the traditional market by analyzing the impact on the business performance of merchants in the traditional market. Based on the existing research on entrepreneurship, psychological characteristics, capabilities, and physical characteristics of the market were considered as merchant characteristics. As a result, the risk characteristics and merchant pride, which are internal characteristics of merchants, have a significant effect on business performance. Among the competencies of merchants, product competency, customer management competency, and price competency were found to have a significant impact on business performance. Among the physical characteristics of the market, reputation and product diversity were found to have a significant effect on business performance. The results of this study are meaningful to empirically prove the relevance of the merchant's internal characteristics and capabilities, and the market's physical characteristics to the business performance of market merchants. Could be utilized. However, the limitation of this study is that there may be differences in each industry in the case of market merchant products. In future studies, empirical studies on the trader's relevance to business capability and business performance should be continued.

In Cheongsong area, very rare spherulitic rhyolites both in Korea and foreign countries occur as dykes showing various types. The spherulites in them represent an undercooling caused by very fast cooling of the dykes in a shallow depth near to the surface and the variety of types were resulted from the difference of relative cooling rate. Cheongsong spherulitic rhyolites can be classified into five types; radiated simple spherulite, layered simple spherulite, layered multiple spherulite, radiated-layered multiple spherulite, radiating layered multiple spherulite. Radiated simple and radiating layered multiple spherulites formed by diffusion current caused by undercooling related to very fast cooling. On the other hand, layered multiple spherulites formed by relatively slow diffusion as a Liesegang ring during relatively slow cooling. If the cooling rate is between the two cases, layered simple spherulites formed. This interpretation indicates that Chrysanthemum, Dandelion, Dahlia and Sunflower types which are included in radiated simple or radiating layered multiple spherulites formed in the dykes with the fastest cooling rate in Cheongsong area while Peony, Rose and Innominate types classified as layered multiple spherulite formed in the dykes with the relatively slowest cooling rate. At the cooling rate between them, Apricot type spherulite formed. The K-Ar age-dating for Cheongsong spherulitic rhyolites indicate them to be formed between 48 and 50 Ma. The Cheongsong rhyolites are very valuable for research and preservation because of their rarity, beauty and diversity.

As a commemorative joint survey for the 20th anniversary of the Korean Society of Systematic Zoology, molluscan fauna of Jindo Island was investigated from the materials collected from 3 localities of Jindo Island from 29th to 30th of June, 2004. A total of 77 species of 37 families were identified. Among them, 26 species of 18 families are reported for the first time in this area, including Onchidella kurodai (Taki, 1935) that is new to Korean fauna. For O. kurodai, external morphologies were described in detail with illustrations. Combining the present data with those of the previous works revealed that a total of 115 species from 43 families have been recorded in Jindo Island and its adjacent areas thus far. From a biogeographic point of view, some gastropod species (Bittium craticulatum, Mocroschisma dilatatum, Cantharidus japonicus, C. callichroa, Homalopoma sangarense, and Crepidula onyx) encountered from Jindo Island were the species previously recorded in the southern and/or eastern offshores of Korean peninsula, including Jeju Island (Choe, 1992). Along with the fact that Jindo Island contains a large number of molluscan species ranging over the Yellow Sea coast, this finding is another line of evidence supporting the Kim and Kwon (1983)'s idea that this area is an overtopping zone of marine organisms which dwell in both the Yellow sea and southern part of Korean sea waters. No comprehensive faunistic survey was not made in the present study. We expect that further supplementary study would generate more biogeographic and faunistic knowledges than what we understand through the present study.

The crab, Macrophthalmus (Mareotis ) japonicus , collected in 1983 from CHojijin tidal flat, southeastern part of Kangwha Island , Korea, was studied. Its caraace breadth, the carapace length , and body height were checked , and the measured raw data were analysed for the growth ratios by the mode subtraction method from the frequency distribution compared with the probability graphs. The growth rate of the crab rose more in summer than in fall and exceeded 10% during the same period on Chojijin tidal flat in Kangwha Island , Korea. Four size groups of the crab appeared in June, 1983 , but they were put together into only on emixed group by autumn. The rapid growth of the crab in summer in middle latitude comes from the seasonal bio-rhythm and the best conditions for food. But the physiological activities of the crab are reduced from autumn and the growth rate reaches the upper limits in many individuals on this tidal flat. The more the crabs grow, the more the breadth ratios to the carapac length become larger and the slopes of correlation curve get smaller. The measured values from the carapace breadth of the crab are more useful for morphological studies than those values from the carapace length or body height.
