  • Reaction by neighbours to odours is increasingly affecting operations of existing animal farming operations and may adversely constrain the further development of the animal production industry in some parts of Australia. It is critical that the scale of such odour impact on the rural-urban interface be estimated to provide useful information both for environmental protection and animal farming operations. Furthermore, the information can be used to modify odour reduction strategies as economic conditions change. The Centre for Water and Waste Technology at The University of New South Wales has developed a comprehensive set of odour control techniques in the course of its research and development effort over the past eight years. Techniques have been developed for odour sampling at point, area and volume sources, monitoring environmental parameters such as ventilation rate, shed temperature, shed humidity, litter water content and ambient meteorological condition, olfactometry and odour dispersion modelling. The work has paved the way for the establishment of odour reduction strategies based on best environmental management practice and advanced odour abatement technologies.

  • To select fruit trees suitable for shaded urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Malus domestica 'Fujii', Prunus mume, Prunus persica for. persica, Rubus fructicosus, and Vaccinium corymbosum 'Reka', leaf growth in response to different light was investigated two years after 35% shade treatment. Leaf area of E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, P. persica for. persica, and V. corymbosum 'Reka' increased in shading. Fresh weight of leaves make inconsistent response to shading in every species but dry weight of E. umbellata var. coreana and P. persica for. persica showed the highest 150% and 148%, increment, respectively. Althought leaf water content of E. umbellata var. coreana decreased in shading, there is no difference in P. persica for. persica. Chlorophyll value of E. umbellata var. coreana and P. persica for. persica that showed higher than any other species is correlated with dark leaf green. Compared to specific leaf weight of E. umbellata var. coreana, P. persica for. persica, and V. corymbosum 'Reka' showed lower than any other species in shading, that of M. domestica 'Fujii', and R. fructicosus increased in reverse. These results indicate that E. umbellata var. coreana and P. persica for. persica that showed high value in several invesetigaton items are suitable for shady urban condition considering leaf growth in response to shading.

  • In this study, the effect of void formation resulting from gas hydrate dissociation or loss of some particles within soil structure on the strength of soil is examined. Beag-ma river sands with uniform gradation were used to simulate a gas hydrate bearing or washable soil structure. Empty capsules for medicine are used to mimic large voids, which are bigger than soil particle. Beag-ma river sand was miced with 8% cement ratio and 14% water content and compacted into a shear box. The number and direction embedded into a specimen. After 4 hours curing, a series of direct shear test is performed on the capsule embedded cemented sands. Shear strength of cemented sands with capsules depends on the volume and direction. The volume and direction formed by voids are most important factors in strength. A shear strength of a specimen with large voids decreases up to 39% of a specimen without void. The results of this study can be used to predict the strength degradation of gas hydrate bearing sediments after dissociation and loss of fine particles within soil structure.

  • 216 groundwater samples for inorganic constituents and 168 samples for VOCs in the Ulsan urban ares and analyzed to relate groundwater chemistry to four land use zones, residence․commercial, industrial, agricultural, and forestry. In general, Na and Cl concentrations in groundwater were high in residence․commercial zone near Taehwa river due to residual saline. Although NO3 contents is high in agricultural zone and VOCs content is high in industrial zone, it seems difficult to relate groundwater pollution to land use zone. Even though groundwater pollution of the area is still low, continuous monitoring is necessary because the city is expanding.

  • The new paradigm of urban regeneration, would promote the comprehensive communal view. Therefore, the community role has become an important and necessary for regeneration of communities. It is necessary for urban regeneration which should be matched with the regional characteristics, to develop an evaluation framework that can objectively and accurately diagnose the status of community; so it can be an integrated prescription. A new alternative, asset-based approach may be an alternative to build the community based on opportunities and strengths, which focuses on community inside and things that community have. In this study, a community asset is defined as the tangible and intangible components in the community. A community asset evaluation system is developed through the content analysis related to previous studies of several researchers who investigated the asset-based approaches. Community assets are classified into seven types: human, social, cultural, natural, physical, economic, and political property. Each type is classified into components and establish as a framework with 3 levels in order to set the indicators which can be measured concretely.

  • Infiltration facilities are effective instruments to mitigate flood and can increase base runoff in urban watersheds. In order to analyze effects of infiltration trenches physical model experiments were conducted. The physical model facility consists of two soil tanks, artificial rainfall generators, tensiometers, and piezometers. The experiment was conducted by nine times and each case differed in rainfall intensity, rainfall duration and the type of ground surface. Measured quantities in the experiments are as follows: surface runoff, subsurface runoff, trench pipe runoff, groundwater level, water content, etc. The following resulted from the model experiment: The volume of subsurface runoff at trench watershed was maximum 78.3% compared with rainfall. This value is bigger than that of ordinary rate of subsurface runoff, and shows a groundwater recharge effect of trench. The time of runoff passing through the trench became earlier and the volume of runoff became larger with the increase of inflow into the trench, while trench exfiltration into ground became relatively smaller. The results of this study presented above show that infiltration trenches are effective instruments to increase base runoff during dry periods.

  • The purpose of this study is to investigate the family values and the factors of satisfying family life. Throughout the study the changes of family values and marital satisfaction were examined. The results of the study are as follows; 1) Whereas the family values of people living in urban community were modernized to a great extent- in position of wife, role of husband and wife, preference between son and daughter, view on filial piety- the family values of people living in rural community were remained its traditional form. Form both areas modernization of family values was found in support of old parent. 2) Both Seoul and Andong showed the significant difference on family values according to subjects' education and age. In Seoul, the socio-economic level was influential factor in determining subjects' family values. 3) Marital satisfaction was found higher among people living in rural community than in people living in urban community. Since its very important not only to the individual but also to the society for a human being to be content in his surrounding , the reestablishment of the housewives family values should be followed so that other family members may approach the modernized family values.

  • Purpose: This study was conducted to explore the experiences of women with osteoarthritis in the community-based aquatic exercise program. Methods: A total of 13 women who lived urban-rural complex areas participated in 8 weeks of aquatic exercise. Data were collected from two focused group interviews of those who signed informed consent. Results: Four categories emerged from the contents analysis: 1) assisting a remedial program (participant-centered education, alleviation of physical symptoms, and relieving stress), 2) Pleasure of being together (group exercise, feeling of pleasure and joy, and strong and confident supporter), 3) burden of participation (economic burden, low accessibility and unaccustomed swimming pool), 4) organizing and activating a self-help group(acquired confidence over exercise, hoping for continue exercise, and Needs of self-help meeting). Conclusion: Aquatic exercise was good for women living urban-rural area as it gave not only reliving arthritic symptoms but also improving social relationships. It is optimal to assist in making of a self-supporting group and continuing activities through it.
