Considering to the geochemical behaviors and environmental changes of bottom sediments in streams, Gwangju metropolitan city, this study focuses to analyses on grain sizes, metal elements and organic carbons in sediment samples from Yeongsan and Hwangryong rivers, and Gwangju stream. In the sediments, contents of Cu, Zn, Pb, P and TOC were highly variable, in the case of Gwangju stream particularly. Yenogsan and Hwangryong rivers are influenced by grain sizes and surrounding geological settings and Gwangju stream is connected to organic matters related to life fouls and so forth, with respect to the geochemical behaviorof bottom sediments. Li, Zn, Pb and Cu were enriched in Yeongsan and Hwangryong rivers and Li, Cu, Zn, Pb and P enriched in Gwangju stream, respectively. In the heavy metal contamination of above drainages, the site mutually connected Seobang(GJ 4) with Donggye(GJ 7) streams shows the highest values, in peculiar. It is inferred that those contamination values are mainly related with urban foul waters in the city.

This study is aimed to find out distribution status of online-market livestock products by purchasing and examining 120 cases of livestock products (seasoned meat: 17, 33 cases of packaged meat, 23 cases of ground meat, 19 cases of ham, 11 cases of sausage, 4 cases of bacon, 1 case of meat processing, 8 cases of Meat extract processed, and 4 cased of Dry storage of meat) at 17 On-line markets from April to August. 2015. We checked the weight of them first, and carried out ingredients test for each of processed meats. And we performed gene screening test on the products which were labelled 'Hanwoo' to investigate that the products were made of Korean native cattle. we also carried out test of identifying domestic animal species on ham, sausage and ground processed products. After weighing all products, we could know that all of them were delivered more than labelled weight or in allowable error. The result values of test which measured level of preservatives, Nitrite, Volatile Basic Nitrite (VBN), and tar Color by the type of processed meat products were in permissible range or not detected. Also, 17 beefs inspected Korean native cattle gene test were confirmed that they were made by real korean native cattle. But 2 cases of Ham, sausage, and ground processed products had difference between label and goods. In this study, we could make a decision that livestock products, distributed in On-line markets, were safe and expect to make higher degrees of hygiene for livestock products seller. Futhermore, we hoped result of this study could be used by basic data for progressive national policy decisions.

Citizen participation or resident participation is perceived as an effective way to correspond to the diverse urban problems, especially in the area of residential environment improvement projects and community activities. As the leading city of the Honam region and a core middle city leading the development of the southwestern region, Gwangju city is planning and under-developing new Housing Complexes and Urban Renewal Projects. The purpose of this study is to identify the perception of Gwangju citizens on resident participation in community activities to suggest diverse strategies for improving quality of citizen's life and making better living environment. For the research purpose, 1,380 questionnaires were distributed to the Gwangju citizens who live in 5 autonomous districts -Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu- and 601 were used in data analysis. Although citizens in Dong-gu showed the lowest settlement consciousness, they required the highest level of need for resident self-help activities. Contrastingly, Seo-gu showed the highest level of settlement consciousness and the lowest need for resident self-help activities. Based on the results, high quality community facility should be provided to promote residential satisfaction and consciousness of residential participation and self-help activity must be improved. And also, diverse strategies for resident participation including development of resident education programs and search for regional resources should be covered in further research.

The present study was carried out to investigate the incidence of Campylobacter spp. from the chicken carcasses in slaughterhouse. A total of 9 strains were primarily isolated from enrichment culture and selective culture of the sample with candle and microaerophilic chamber method. Nine of Gram-negative, catalase-positive and oxidase-positive strains were further isolated by the determination of biochemical characteristics and finally identified as Campylobacter jejuni with HIP 400F and HIP l134R primers. Therefore, this PCR method proved to be useful as a routine diagnostic test for the Campylobacter detection and confirmation of C. jejuni and C. coli in naturally contaminated poultry samples.

Gwangju Metropolitan Government & Ministry of Environment have signed a model city in response to Climate Change agreement. The agreement calls for Gwangju to cut greenhouse gas emissions 10% below 2005 levels by 2015. Gwangju has seen this agreement as an opportunity to cut pollution and conserve the environment as well as to reinvigorate local economy. According to policy of Gwangju, Gwangju held design competition for Gwangju City Arboretum on march, 2009. The purpose of design competition was to give a wide publicity to Gwangju as Hub City of Asian Culture and construct carbon-neutral arboretum in accordance with the policy of 'Low-Carbon and Green Growth'. First of all, a design concept of arboretum is 'winding, round, overlay 'to reflect the landscape of Nam-do which is surrounded by mountains and river flows through the village. Second, the arboretum has five different places with these themes - Forest of Festivals, Health, Nature, Nostalgia, Education and Future. Each place has a symbolic theme park and different flow planning respectively. Third, the most critical point is that the arboretum is a carbon-neutral park. Gwangju arboretum will soon be developed in metropolitan sanitary landfill and constructed as the O2 arboretum based on low carbon strategy. Fourth, the O2 arboretum suggests specialized issue : 'Energy Saving', 'Recycling System', 'Green Network', 'Water System(rainwater maintenance and wetland development)'. Besides, main buildings(greenhouse, visitor center, Nam-do experience exhibition hall, and forest museum) is designed in consideration of harmony with topography character, surroundings. Also, planting will be a multilayer plant based on native landscape trees in consideration of function and the growth characteristics.

The purpose of this study is to address the progress of the heat island phenomenon and the scheme to decrease in heat island phenomenon through analysis of micro-climates according to land use and make a plan to construct wind ways. The result is: 1) Analysis of temperature and humidity at 6 spots for 24 hours showed that heat island phenomenon was considerably intense around center road of Gwangju and can be mild through making lakes and green zones. 2) Analysis of the direction and velocity of the wind at 2 spots for 24 hours showed that the direction of the wind at the center of Gwangju was SSW(South-South-West) and average velocity of the it was $1.2{\sim}1.5\;m/s$. To make the inflow of the low-temperature air current from Mt. Mudeung into the city through Gwangju river, efficient management of Gwangju riverside parks should be considered for Gwangju river itself to be wind way. 3) Analysis of mobile temperature measurement on 3 courses for 24 hours showed that the low-temperature air current of Mt. Mudeung and a micro-climate of Gwangju river can lighten thermal storage phenomena of the city in that the temperature was lowest at Gwangju riverside. These outcome is from a day term measurement. So, to figure out accurate condition of heat island phenomenon in Gwangju City, it is needed to have long term measurements and accumulation of those information.

Ptaquiloside는 고사리에 들어 있는 발암성 물질이다. 본 연구는 다양한 조리법에 따라 고사리에 함유된 ptaquiloside을 측정해 보고자 하였다. 조리법은 가열, 물에 침지, 물교환 횟수 등이었다. 알칼리 가수분해와 용매분획은 ptaquiloside를 화학적으로 안정한 물질인 pterosin B로 전환시켜 주었다. Pterosin B 함량은 이동상용매로 3 mM ammonium과 메탄올 용매를 사용하여 UPLC-MS/MS로 분석하였다. 조리과정이 없는 생고사리의 $H_2O$추출물에 함유된 pterosin B함량은 81 mg/kg으로 검출되어 독성물질 ptaquiloside는 46.4 mg/kg이었다. 5분의 가열 시간 후 고사리의 pterosin B 함량은 약 60%정도 제거시켜주며, 이 중 2/3는 ptaquiloside에서 전환된 pterosin B가 아닌 고사리 고유의 ptersoin B 함량이었다. 12시간 침지를 추가한 고사리는 처리하지 않은 고사리에 비해 약 88%, 또한 매시간 물교환 작업을 추가시 99.5%까지 제거됨을 알 수 있었다. 따라서 독성물질 ptaquiloside의 제거는 가열시간과 더불어 침지와 물 교환 횟수도 동시에 이루어져야 함을 알 수 있었다.
