In recent years, concerns have been growing globally regarding greenhouse gases. Open burning of biomass causes emission of a number of greenhouse and other gases and substances. This paper studied an analysis on the characteristics of four types of biomass using duel type cone calorimeter. Cone calorimeter is widely used for assessing combustibility of materials in Europe. As a result, we evaluated several characteristics of biomass, such as heat released rate, smoke production rate, CO, $CO_2$ production and mass loss rate, and so on. $CO_2$ is currently responsible for over $60\%$ of the enhanced greenhouse effect, and may be the most important contributor to future. $CO_2$ production for biomass in the range of $1.74\~1.99kg/kg$ is similar to previous research conducted by Bhattacharya et al. (2002a).

Nonpoint source pollution characteristics of recreation park was investigated. Runoff ratio of recreation park ranged 23-57%, which was lower than other urban area since impervious area was less than 37%. The average BOD, COD, TOC, SS, T-N, T-P, were 14.09, 32.86, 12.19, 121.51, 7.78 and 0.72 mg/L, respectively. First flush of recreation park was analyzed by normalized cumulative load - volume curve and mass first flush ratio(MFFn), MFF10 for BOD, COD, SS, T-P, T-N, TOC were 2.90, 1.59, 2.15, 2.74, 2.60, and 1.59, respectively. Observed data showed that 62% of pollutant could be removed by storaging 5 mm rainfall-runoff and even 3 mm depth could store up to 50% of pollutant in runoff.

The Uminonakamichi Seaside Park is located in Fukuoka and extends over an area of 540 ha. This Park is directly developed and managed mainly by the national government for its use for recreational facilities serving a wide area. It is planned and developed as an urban resort-type park, exploiting the rich natural environment of the area, to serve urban residents in northern Kyushu. The management of the Park is jointly conducted by nine bodies, including the national government and private enterprises. The Park has several functions, ranging form an urban resort to conservation of the natural environment and education. The Park has so far been positively evaluated by its visitors. However, the social background for the Park is changing and the park is now facing changing needs for this type of park, necessitating coordination with the development around the Park and a need to respond to the recent fiscal structural reform. Further improvement of the visitor services and the reconfirmation of the government's role in the development work are essential for the maintenance and enhancement of that attractions of this Park in the coming years.

As sustainable development and environment-friendly efforts in large-scale development projects emerge as major interests at home and abroad, man-made wetlands and eco-park facilities have been newly planned or created when developing reclamation districts recently. In this study, based on findings from a comprehensive review of relevant studies and planning cases, the basic direction and objectives of the plan were developed. A comprehensive analysis on the status of ecological environment and demographic and social environment showed that the planned site is in a process of migrating from early stages of reclamation to middle stages. It was planned for the eco-park to function as a major base along an ecological network consisting a freshwater lake and rivers and streams flowing into the lake in Hwaong District. Through a master plan and sectoral plans were planned according to desalination levels after reclamation. Then, habitats for livings organisms were also planned. The eco-park, the planned site, is also in a process of migrating from the early stages to middles stages. By creating an eco-park that considers post-reclamation ecological environment changes, natural succession processes will be preserved, which is expected to help local ecosystems to restore their functions on their own over a relatively long period of time and enable to observe the restoration process.

The purposes of this study were to understand visitors' park use characteristics and provide effective directions fur managing facilities and programs of ecological interpretation in Incheon Grand Park, Korea. To accomplish the purposes of study, a questionnaire survey with 376 samples was carried on the park. As for the results, most respondents were pointed relaxation with natural environment as a main visiting purpose. Visitors highly interested in programs of ecological interpretation and also respondents' intension of participation to those programs showed far more positive. Based on the results, there was a need fer introducing facilities and programs of ecological interpretation as a park management strategy in order to induce nature-friendly park use and connect to environment education in the school system. In addition, some suggestions which should be developed a base facilities and various programs were made.

There has been a conflict over the use of private forest in Mt. Jiri National Park among the stakeholders. Therefore, the purpose of this study is to define each stakeholders' recognition difference about value and conflict of Mt. Jiri National Park and find the possibility of creating agreement point for solving conflict. For the purpose, the study performs factor analysis on the value of national park and conflict factor and abbreviates them to 4 factors respectively. The study classifies and compares the recognition difference among the stakeholders with t-test and Duncan multiple comparison. The result of this study is that village residents, Korea Forest Service and local autonomy share the same recognition about the value of national park but National Park has different recognition. Regarding the conflict, National Park, Korea Forest Service and local autonomy share the same recognition but village residents have different recognition. Regarding the organization of conference as a direction to solve conflict and its reason, all of the stakeholders share the same recognition. It is necessary to adopt clear standard for the use of forest and apply the different execution of regulation to each area.

This study was carried out to investigate the prevalence of fascioliasis of slaughtered and farmed cattle in Gwangju area from February to November in 2007. A total of 1,000 cattle fecal samples were collected from slaughter houses (n=805) and farms (n=185). Twelve (1.2%) were found as positive cases with excretion of the egg of Fasciola spp in the fecal specimens, and 128 (12.8%) were positive in intestinal parasitism using the flotation and sedimentation procedures. The infection rate of fluke larvae from the slaughtered cattle at abattoirs in Gwangju was 0.75% (6 out of 805 heads). In histopathology, there were several liver lesions such as inflammation with infiltration of eosinophil, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissue, calcification and abscess formation.
