This study investigated the population densities and diversity of heterotrophic bacteria, and the rhizosphere-to-soil ratios (R/S) in the rhizosphere soil of halophyte Phragmites communis at the western coastal mudflats of Korea. The population densities of aerobic heterotrophic bacteria on the rhizosphere soil of P. communis were in the range of $3.3\;{\pm}\;0.9\;{\times}\;10^7\;{\sim}\;1.2\;{\pm}\;0.5\;{\times}\;10^8\;cfu\;g^{-1}$ dry weight (d. wt.). Population densities of amylolytic bacteria ranged from $1.1\;{\pm}\;0.2\;{\times}\;10^6$ to $3.0\;{\pm}\;1.2\;{\times}\;10^6\;cfu\;g^{-1}\;d.\;wt.$, while those of cellulolytic bacteria and proteolytic bacteria ranged from $5.6\;{\pm}\;2.3\;{\times}\;10^6$ to $1.5\;{\pm}\;0.3\;{\times}\;10^7\;cfu\;g^{-1}\;d.\;wt.$ and from $1.4\;{\pm}\;0.3\;{\times}\;10^6$ to $3.5\;{\pm}\;2.3\;{\times}\;10^7 \;cfu\;g^{-1}\;d.\;wt.$, respectively. The R/S ratios ranged from 2.26 to 6.89. Genetic (16S DNA) analysis of fifty-one isolates from the roots of P. communis suggested that the dominant species were closely related to the ${\gamma}$-proteobacteria group (18 clones) and the ${\alpha}$-proteobacteria group (14 clones). We found that halophyte species and mudflat environment both affected the rhizosphere bacterial communities.

Iriai an Indigenous forest management system in Japan from the viewpoint of "common pool resources" was a success resilient institution and resulted with sustainable production system and environmental conservation. This study was conducted in Osawa of the Nagano prefecture through group discussions, field observations and an in-depth field survey. Osawa Property Ward Forest is managed under the concept very much similarly to traditional "Iriai". This study firstly examined the changes of collective forest management system in terms of awareness and interest in forest management; forest management activities; role of forest; and collection of forest products. Then it analyzed the current threats for collective forest management have been identified as: land abandonment due to loss of benefits and lack of active community participation; deterioration of forest environment particularly the micro-climate and aesthetic values; conflict with local government authorities restraining the use of money in property ward forest and conflict with outsiders on damping of the garbage. Community cantered forestry management rules; livelihood contribution; protection of environment; local initiatives for protection and economic activities are the prevailing opportunities for collective forest management. The main requirements for revitalization of collective forest management are explained as local reciprocity; imposition of community based forest rules; encouraging local innovations; and building partnerships with stakeholders. Collective forest management system addresses the limitations of conventional forestry models, which had invalidated traditional 'iriai' institutions, and key to restoring sustainable use of forest and environmental resources. Cross-institutional collaborations together with responsibilities of local communities would ensure the revitalization of forest resources.

To investigate the effects of pipe materials on biofilm accumulation and water quality, an annular reactor with the sample coupons of four pipe materials (steel, copper, stainless steel, and polyvinyl chloride) was operated under hydraulic conditions similar to a real plumbing system for 15 months. The bacterial concentrations were substantially increased in the steel and copper reactors with progression of corrosion, whereas those in stainless steel (STS) and polyvinyl chloride (PVC) reactors were affected mainly by water temperature. The heterotrophic plate count (HPC) of biofilms was about 100 times higher on steel pipe than other pipes throughout the experiment, with the STS pipe showing the lowest bacterial number at the end of the operation. Analysis of the 16S rDNA sequences of 176 cultivated isolates revealed that 66.5% was Proteobacteria and the others included unclassified bacteria, Actinobacteria, and Bacilli. Regardless of the pipe materials, Sphingomonas was the predominant species in all biofilms. PCR-DGGE analysis showed that steel pipe exhibited the highest bacterial diversity among the metallic pipes, and the DGGE profile of biofilm on PVC showed three additional bands not detected from the profiles of the metallic materials. Environmental scanning electron microscopy showed that corrosion level and biofilm accumulation were the least in the STS coupon. These results suggest that the STS pipe is the best material for plumbing systems in terms of the microbiological aspects of water quality.

The wind field measurement of severe winds such as hurricanes (or typhoons), thunderstorm downbursts and other gales is important issue in wind engineering community, both for the construction and health monitoring of the wind-sensitive structures. Although several wireless data transmission systems have been available for the wind field measurement, most of them are not specially designed for the wind data measurement in structural wind engineering. Therefore, the field collection is still dominant in the field of structural wind engineering at present, especially for the measurement of the long-term and high-frequency wind speed data. In this study, for remote wind field measurement, a novel wireless long-term and high-frequency wind data acquisition system with the functions such as remote control and data compression is developed. The system structure and the collector are firstly presented. Subsequently, main functions of the collector are introduced. Also novel functions of the system and the comparison with existing systems are presented. Furthermore, the performance of this system is evaluated. In addition to as the wireless transmission for wind data and hardware integration for the collector, the developed system possesses a few novel features, such as the modification of wind data collection parameters by the remote control, the remarkable data compression before the data wireless transmission and monitoring the data collection by the cell phone application. It can be expected that this system would have wide applications in wind, meteorological and other communities.

The purpose of this study is to investigate how the hollowization in rural villages which causes marginal villages appears in Korean rural villages and whether the hollowization has relation with decrease and aging of population or not. For achieving the research objective, survey was carried out focused on Geumsan-gun. As a result, it confirmed that rural out-migration and rural decline especially in 'people', 'land(economic situation)' and 'community' have being progressed. Also variance analysis and regression analysis were executed with using the number of population and the ratio of people over 65 as dependent variables and using each survey contents(variables) as independent variables. The results of analysis showed that the ratio of people over 65(+), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), programs for urban-rural interchange(+), and the implementing public projects(+), etc. have a relation with the number of population(-) and the number of population(-), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), activities of communities(+), and the implementing public projects(+), etc. have a relation with the ratio of people over 65(+) (+: increase, -: decrease). So the hollowization in people', 'land(economic situation)' and 'community' has direct relation with decrease and aging of population in rural areas.

This study examined the recognition differences between local residents and national park managers on the adjustment of national parks which are conducted every ten years for the purpose of providing basic information for the park management, according to the Natural Parks Act. Both local residents and national park managers positively perceived the adjustment of national parks, but park managers showed concern towards the damage of natural resources resulting from the cancellation and adjustment of restricted development districts in Korean national parks. Local residents are more likely than park managers to recommend boundary adjustment in other national parks regarding the influence of parks adjustment on local change. While local residents recognized that the boundary adjustment of national parks improves the level of community management, park managers focused on damages on the local environment and the park landscape adjacent to the areas. The result shows the recognition differences of local residents and park managers. Further research into adjustment of national parks is necessary to diminish perception gaps among stakeholders and develop prediction indicators of cancellation effect in response to the future cancellation areas of national parks through the characteristics of cancellation communities, revitalization of local economy, and environmental change of local community.

Low back pain is generally defined as a complex symptom rather than a specific diseases entity, especially when musculoskeletal lesions of the low back, neurogenic, vasculogenic and discogenic lesions are present. Sixty to eighty percent of all human being have experienced low back pain once or more times during in their lifetime. Low back pain is a one of the commonest cause of physical impairment and induces disability the activities of everyday living or the activities of work. Today, low back pain plays important part for the loss of working capability from social, industrial field and individual daily life. But there are no study about incidence and prevention program of low back pain in rural peoples. This study was conducted to find out current status and characteristics related to low back pain in rural peoples(especially engaged in agriculture), so that could provide basic data to establish prevention program for them. The data were gathered from 301 rural adults(female 62.1%, male 37.9%) with low back pain by the structured interview in the 4 communities(south and north Gyeong-sang Do and Chung-cheong Do), and sampled at local hospital, local clinic, and health clinic center in May, 2000. The results were as followed. About one third of cases(35.5%) were aged from 60 to 69, 34.6% were smoker, and 91.4% not used to regular exercise. Low back pain frequently due to intervertebral articulopathy(42.5%), follewed by herniated intervertebral disk(19.9%), sprain(17.3%), vertebral dislocation(4.0%), and etc(16.2%). Above half of cases(56.5%) were a eight-hour workday, and 61.8% complained of low back pain during work. Mostly, period of agricultural experience was more than 20 years, and cultivated more than 2 crops. Low back pain is common to rural adults, therefore adequate resting time from work and lumbar strengthening exercise program needed to prevent low back pain in rural peoples.
