Place based intervention has become an important strategy for the ubiquitous city initiative. However, the role of the ubiquitous built environment in determining urban quality of life has not investigated fully. Using place as a relational space where people access u-infrastructure, u-health and u-services, this paper examines the relationship between spatial variations in the provision of ICTs and the spatial reconfiguration of quality of life operating at different geographical scales across Australia. Based on a case study of the state of Queensland in Australia, we emphasize the need for a place based approach to ubiquitous technologies and infrastructure provision in different socio economic hierarchies of space and place.

For the comfortable housing life, an urban environment should give comfort and pleasantness to people living in house and in city. There are lots of environmental conditions in city affecting house and life and most of all the noise pollution have been become factor that makes people's life hard without need to say. Recently researches have been performed to create comfortable urban environment and a study on the evaluation of urban environmental sounds is now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out evaluation method for urban environmental sounds. Vocabularies applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time.

Animal and clinical studies as well as epidemiological data have provided convincing evidence that n-3 polyunsaturated fatty acids can protect against atherosclerosis. However, the effects of the fatty acids on atherogenesis are contradictory. This discrepancy could derive from great susceptibility of the fatty acids to oxidation. We investigated the effect of eicosapentaenoic aced(EPA) on cellular atherogenesis via the scavenger receptor of THP-1 derived macrophages. THP-1 cells were fully differentiated into macrophages by incubating with phorbol 12-myristate 13-acetate for seven days. Atherogenic features of EPA were compared by subsitituting for linoleic acid (LA). Macrophages were also incubated without treatment of the fatty acids as controls. EPA (5-50 nmol/mL) was not cytotoxic and did not measurably induce cellular oxidation compared to bovine serum albumin (BSA) vehicle or identical doses of LA. EPA increased macrophage uptake and degradation of acetylated LDL(AcLDL) up to 14% and 88%, respectively. EPA increased markedly total cellular sterol synthesis and heparin-releasable lipoprotein lipase activity of macrophages, indicating that EPA may enhance accumulation of cellular cholesteryl ester and possibly facilitate formation of foam cells. These results demonstrate that EPA promotes the modified LDL-triggered atherosclerotic process by the modulation of the scavenger receptor and the activation of LPL in macrophages.

The purpose of this study is to survey the learner’s need achievement, interest and practical level of the learning objectives according to the teacher’s teaching method in home economics of middle school(Dietary Life Unit), to examine the differences according to the local situation, and to get some information to improve the teaching method. This study surveyed the eight units of dietary life with 459 students in the rural community (224 students) and Seoul(235 Students). The collected data were analyzed by T-test, F-test. To sum up this study are as follows: 1. When the need, achievement, interest and practical level of unit “food”are compared the students of seoul with those of rural community, the student of Seoul show high in “The use of Processed Foodstuffs” and low in “Cooking the Processed Foodstuffs.”The student of rural community show in “A kind of Cooking Method”and low in “Environment and Food Life”. 2. The need, achievement, interest, practical level of the whole unit in rural community is higher than those is Seoul. 3. According to teaching method, comparison Seoul with rural community is revealed as follows. Seoul region is revealed significance to discovery learning in “Cooking Foodstuffs(The achievement and interest level) and ”Environment and Food Life”(interest level). Rural community is revealed significance to discussion learning in “The constituent and Food Life”(The need level, interest level). Rural community is revealed significance to explanation learning in “Environment and Food Life”(The achievement level).

This study investigated the general trends and differences in the working life of overseas Korean women. The subjects were 872 working Korean women over 20 years of age living abroad in America, China, and Russia Central Asia. The subjects completed a questionnaire on working life and the data were analyzed using SPSS. The working environment of Korean-American women was not stable. Many Korean-American women worked to help the home economy. They were paid by the hour, day and week. On the other hand, many Korean-Chinese women worked for self-achievement and usually for 8 hours a day. The working life of Korean women in Russia Central Asia was not good. They had a small income and worked to help the home economy. The first variables for changing their occupation were income and bonus. Despite their unstable working environment, overseas Korean women estimated their working life positively. They rated scores higher than the median on job satisfaction, business importance, duty ability, duty adaptation and family support. Job stress showed lower scores than the median. Korean women in Russia Central Asia showed lower scores on job satisfaction, family support, and work time flexibility than the other two groups.

Purpose: This study evaluated of quality of life (QOL) and physical therapy satisfaction (PTS) in caregivers of cerebral palsy children. Methods: Eighty six caregivers in Gwang-ju were examined. The caregivers' QOL was assessed through self-reports using the WHO Quality of Life-BREF (WHOQOL-BREF), and the data was analyzed separately for each of its 5 domains. Physical therapy satisfaction was assessed using a self-reported questionnaire and the data was analyzed separately for the 2 domains. The results were processed by the mean and standard deviation and then verified by ANOVA and a t-test to determine the significant differences in the QOL and PTS. The factors affecting the QOL were processed by logistic regression. Results: Life environment domain of the QOL across the caregivers factors showed a statistically significant difference in age at natal, monthly income and education. The birth order in the cerebral palsy child factor showed a significant difference in the general, physical and emotional domain of the QOL. The PTS showed a significant difference in the delivery of therapy domain and in the birth order and walking condition of the environment domain. Caregivers education was found to be associated independently with the life environment domain of QOL. Conclusion: Because the QOL of caregivers is an important treatment goal for children with cerebral palsy, early family intervention should be considered.

It is well-documented that the major deterioration of coastal RC structures is chloride-induced corrosion. Therefore, regional investigations are necessary for durability based design and evaluation of the proposed service life prdiction models. In this paper, four reinforced concrete jetties exposed to severe marine environment were monitored to assess the long term chloride penetration at 6 months to 96 months. Also, some accelerated durability tests were performed on standard samples in laboratory. As a result, two time-dependent equations are proposed for basic parameters of chloride diffusion into concrete and then the corrosion initiation time is estimated by a developed probabilistic service life model Also, two famous service life prediction models are compared using chloride profiles obtained from structures after about 40 years in the tidal exposure conditions. The results confirm that the influence of concrete quality on diffusion coefficients is related to the concrete pore structure and the time dependence is due to chemical reactions of sea water ions with hydration products which lead a reduction in pore structure. Also, proper attention to the durability properties of concrete may extend the service life of marine structures greater than fifty years, even in harsh environments.

The purpose of this study is to explore the formation process of housing notion for later life of the elderly which is based on one's lifetime housing experiences. Qualitative data was collected through in-depth interviews with 6 highincome, highly educated aged women, who could select their housing and move voluntarily in old age and explain their housing experiences logically. The findings of this study showed that housing notion for later life was formed through a complex process of individual personality, lifestyle, housing experiences, housing values, housing market and period background as well as socio-demographic characteristics. This qualitative study has a significance as a holistic approach to reveal the lifelong experience of elderly individuals which had not been to deal in the quantitative research of housing for the elderly in the meantime.

The chlorinated dioxins and furans have attracted considerable scientific and public concern because of their environmental persistence and super-toxicity through the foodchain. Recent dioxin scandals in several military bases have also contributed to a higher awareness on the side of food consumers as well as foodwaste combustion. However, there is continuing uncertainty over the relative importance of different sources of dioxins and furans to the soil environment. In difference to those awareness there is a main influence of potential soil contamination on the dioxin contents in groundwater. It is, therefore, important to provide a sound scientific framework and basis by which to evaluate the significance of the presence of dioxin in soils. Consequently, we have to identify the characteristics and nature of dioxin released into the soil environment, especially in agricultural aspect.
