To elucidate demersal organism community structure, abundance, and biomass by period and region in the Uljin marine ranching area, otter trawl surveys were conducted at six stations from February 2008 to December 2009. During the survey period, a total of 118 species was collected in the Uljin marine ranching area, including 76 pisces, 27 mollusca and 15 crustaceans. The average abundance of individuals was 806 ind./$m^2$ and average biomass was 31,853 g/m2. The numbers of species, species richness, individuals per area and biomass per area were higher in 2009 than in 2008. Cluster and MDS analysis, based on a Bray-Curtis similarity matrix of fourth root transformed data of number of species and individuals per area, showed division into two different groups of demersal organisms in 2008 (Group 1) and one demersal organism community in 2009 (Group 2). From cluster and MDS analysis using the similarity of the demersal community among six stations, the Uljin marine ranching area was divided into Group A (St. 2, St. 4, St. 5 and St. 6) and Group B (St. 1 and St. 3).

Livestock wastes are considered as major environmental pollutants because they contain high concentration of organic materials. In 2001, The Environmental Department reported that stock farmers were increasing as 5.1%/year, which resulted in a gradual increase in livestock wastes generation. The direct disposal of livestock wastes create several environmental problems. Thus, several countries banned the disposal of livestock wastes in environment including aquatic systems. Recently, aeration-based liquid fertilization was considered as potential way for the disposal of livestock wastes. In this study, next generation sequencing (NGS) analysis was used to understand the microbial community changes during liquid fertilization of livestock wastes. Microbial community was compared with liquid fertilizer physicochemical analysis such as $BOD_5$, $COD_{Mn}$ pH, N (Nitrogen), P (Phosphorus), K (Potassium) etc. The physicochemical parameters and bacterial community results pave the way for producing effective livestock-based fertilizer. By comparing the physical characteristics of the manure with microbial community changes, it is possible to optimize the conditions for producing effective fertilizer.

In the COVID-19 crisis, the elderly over 60 have various psychological health problems such as depression, anxiety, and fear, and the community has become the only space for senior activities. To this end, this study presented a therapeutic aging-friendly community environmental design evaluation system using theoretical review, FGI interview, and hierarchical analysis AHP. The evaluation system is a three-dimensional space, with 10 upper layers and 68 lower layers. In addition, the weight of each index of the evaluation system was distributed through expert survey and SPSS program analysis. First, the material space environment design must satisfy the comfort and health of the elderly when they are active in a common space for their daily life. Second, the design of social space environment is designed to promote exchange and social connection among the elderly. Third, the operating space environment design considers the operating system of the community operating company as important. Through this, it is expected to improve the psychological health of the elderly by providing systematic technical basis and action guidelines for the development of the residential environment of the elderly.

The purpose of this study is to provide suggestion for the establishment of a living information environment for a family-friendly living environment. The survey data on a sample of three hundred and eighty-four married respondents with at least one child in elementary school that were collected for 15 days from April 16 to April 30 of 2010 were analyzed. The results are as follows: It is important to establish a family-friendly living information environment as one of the important elements for a family-friendly living environment. Two aspects ought to be considered in establishing a family-friendly living information environment. One is the supply aspect of the family-friendly living information: this encompasses the usage of facilities in the community, the residents in the community as leaders and the user-friendly living information. The other is the user aspect of the living information, which involves the education on living information for the residents in the community.

To investigate the plant community structure in Gunpo Experimental Forest of Mt. Suri, Kyonggi-do, sixty-four plots were set up and surveyed. By DCA ordination technique, sixty-four plots were divided into seven groups. The dividing groups were * Pinus rigitaeda community, P. densiflora community, P. densiflora-Quercus mongolica community, Q. variabilis community, Q. aliena comunity, Q. serrata community, Carpinus laxiflora community. Though the successional trend of seven communities by DCA ordination technique and DBH class distribution analysis was not clearly inferred, * Pinus rigitaeda community and P. densiflora-Q: mongolica community seems to be trended from present state to Q. spp. community. P. densiflora community, Q. variabilis community, Q. aliena community and Q. serrata community seems to be maintained preaent state and C. laxiflora community will be maintainde stable state. Shannon's diversity was 0.7430~1.3025(unit area: 300m$^{2}$) and soil acidity was pH 4.16~5.13 in surveyed areas.

A drastic development of modern cities and transportation means as part of a rapid industrialization and urbanization for the past half-century has consistently broaden the boundaries of urban dwellers while, at the same time, raising issues as to establishing relationships among them throughout the society following the materialization of modern urban planning. Within the framework of the postmodern concept, there have been consistent efforts to create a community space in appropriate size and, in particular, the concept of New Urbanism and Urban Village that emerged in mid 1800s along with the effort to build a community by building an ideal city provides an important meaning today when people are seeking to restore a healthy community. Against this backdrop, this study aims to explore the concept of community and to determine its optimal scope of implementation in the sense of healing environment under the premise that organizing a healthy city is based on building a solid urban community. The study findings and conclusions are as follows. First, a community is a subject of constant consideration in the process of historical development of the city and has required us to take a variety of strategic approaches and to determine the scope of implementation. Second, the activities of a healthy community have been conducted under various types of environments, including churches, commercial facilities, urban plazas, parks, and streets in various scales, reflecting their unique characteristics. Third, in the process of designing a healthy and sustainable city, determination of location carries significant implications along with building a community of appropriate size, which requires multidisciplinary considerations in addition to functional approaches. Fourth, the composition and design of a modern urban community need to seek practical ways of its implementation within the concept of healing environment.

We monitored antibiotic resistance of Escherichia coli isolates from healthy volunteers of community and chicken butchers from February to July in 2006. From disc diffusion test on 473 E coli isolates from healthy volunteers of the community, the resistance rates of tetracycline, ampicillin, and ticarcillin were 44.8%, 40.8%, and 37.4%, respectively. In the disc diffusion test on 18 E coli isolates from chicken butchers, the resistance rates of tetracycline, nalidixic, streptomycin, and ampicillin were 94.4%, 61.1%, 55.6%, and 50.0%, respectively.
