  • This study is to enhance the provincial leisure plans through various programs and infrastructure facilities and to establish a network of natural leisure areas in Gyeonggi-do. According to the result, first, in terms of analyzing the locations of natural leisure areas by types, the rest of urban parks is formed in the Capital area outside Seoul as centering around the central area. Moreover, with regard to the rest of forest and the rest of natural ecology learning, the area of the detention exceeds the total area of Gyeonggi-do. The rest of valleys and swamps showed a dotted pattern of the detention area while the rest of tideland and fishing village experience indicated a distribution of the detention area along the West Coast as an axis. Second, according to result of analyzing the accessibility of natural leisure areas by types, the rest of valleys and swamps showed the highest accessibility among the natural leisure areas : the rest of natural ecology learning had the medium level of accessibility; the rest of forest indicated the lowest accessibility. Therefore, it is necessary to create more leisure areas concerning the futures demands. In addition, they should be constructed in the places adjacent to the urban district area exhibiting higher usability and accessibility. In the places where there are many natural leisure area with higher utility, management plans should be deliberated as well. Based on the result of analyzing the rest of valleys and swamps and the rest of tideland and fishing village experience, it was found that the natural leisure area should improve the quality of water intensively and hydrophile property and create hydrophilic spaces. The development of natural leisure areas need to be carried out under the principle of environmental protection while considering historic sites and nearby rivers and lakes. Moreover, water leisure programs should be developed actively as well with further utilization of water resources in order to enhance the usability of natural leisure.

  • The Korean Ministry of Environment and Daegu Metropolitan City are establishing the Korea Water Cluster, which will focus on promoting and escalating Korean water industries. The water industry, a future-oriented and promising business sector, is continuously growing each year worldwide, so the project is very timely. In reality, however, challenges still need to be addressed, such as accessibility, logistics systems, social infrastructures, and attracting good companies. For the Korea Water Cluster to be successful, those issues should be solved, but it is difficult to untangle the matters only with efforts of the Korean Ministry of Environment and Daegu Metropolitan City since some issues will require a great deal of both money and time. Therefore, it is important for the Korean federal government to administer support and finances for certain parts of the project, and for the Korean Ministry of Environment and Daegu Metropolitan City to take on other issues to ensure the Korea Water Cluster is successful long-term. The success of the Korea Water Cluster project will result in the Korea Water Cluster becoming a global hub for the future water industries.

  • In terms of the indicators by the type for the landscape plan per the district nit, geographic ecology indicators were the items such as water, water system, topography and climate, while biological ecology indicators were the items such as green zone size, green zone ratio, biotope size and distribution. The sensory and visual indicators were the items such as view point, view axis and skyline, and the accessibility indicator items for the green zone were applied as the socially used indicators. As for the application method according to each indicator, the water or water system was expressed and applied through the slopes and elevation topographic analysis drawings, the climate was expressed and applied through the main direction of the wind and the cold wind pass alley drawings. As for the green zone size and green zone ratio, the land use according to the status and housing area development was compared to present the measured figures. In case of the biotop size and the distribution item, the range was limited to the preparation of the biotope drawings for the focused preservation. As for the view point and view axis, the view point was selected according to the view point to prepare and apply the view analysis drawing in which the view area to be preserved is analyzed. As for the skyline, its landscape photo was composed with the housing area shape, and then skyline photography was applied as the plan in order to propose and consider the various shapes of the skyline. As for the accessibility to the peen zone, the network drawing was drawn to reflect the users' accessibility and continuity of the green zone formed and preserved according to the land use plan and then the drawing was prepared and proposed as the applicable plan.

  • Recent denaturation experiments of bacteriorhodopsin (bR) in the dark and under illumination at high temperatures revealed that irreversible thermal bleaching occurs above ~ 70°C and the preceding reversible structural changes in the dark above 60°C are closely related to irreversible photobleaching observed in the same temperature range (Yokoyama et al. (2002). J Biochem. 131,785). In this study, structural properties of bacteriorhodopsin (bR) at high temperatures were extensively probed by hydroxylamine reactivity with the Schiff base in the dark and hydrogen-deuterium (H-D) exchange in the peptide groups. In the Arrhenius plot from kinetics measurements of the hydroxylamine reaction, a good linear relationship between the reaction time constant and the inverse of the absolute temperature was observed below 60°C, while significant increase started above 60°C, suggesting that remarkable increase in water accessibility of the Schiff base in the temperature region. FT-IR spectroscopic studies on the H-D exchange suggested increase in the deuterium exchanges rate of the peptide hydrogen in the same temperature region.

  • The purpose of this study was to explore the prevalence of hypertension in Haiti and to describe regional characteristics, and thus to speculate Haitian specific regional risk factors. This is a descriptive and comparative study. Subjects were 145 male/female Haitians, who aged between 30 and 59 and have lived in rural areas, had their hypertension indicators being screened. Data were analyzed with descriptive statistics, t-test and ANOVA. More than four fifth of the subjects (82.8%) showed pre-hypertensive or moderate to severe hypertensive condition. 65.5% of the total had abnormal pulse pressure ($PP{\geq}50$) and 13.8% of the sample showed tachycardia (Heart $Rate{\geq}100$). Female Haitian tended to have higher diastolic blood pressure and faster heart rate than male Haitian. The residents who lived in Part 5-1 area with less accessibility to drinking water tended to have higher systolic and diastolic pressure. Hydration status of Haitians was highly considered as an affecting factor on the distribution of hypertension as evidenced by different level of accessibility to drinking water.

  • In this study, we derived seven customer value factors to evaluate the levels of service in wastewater utilities required by customers. Levels of service according to the customer value were categorized into environmental amenity, accessibility of wastewater service, affordability of wastewater charge, quality of wastewater service, health and safety of wastewater service provision, reliability and responsiveness of wastewater service provision, and satisfaction of customer service. To investigate the levels of wastewater service, questionnaires were prepared according to the customer value factors, and the questionnaire survey was performed with 800 adults in all over Korea including male and female samples. The comprehensive satisfaction score for the wastewater service was 57.5 points, indicating a slightly good satisfaction level. The detailed analysis of the result showed that the satisfaction level was high in the wastewater service accessibility and call center service provision but it was relatively low in the river water quality and nasty smell of wastewater. It was concluded that the quality of wastewater service and customer service satisfaction need to be elevated primarily in order to improve levels of wastewater service required by the customers.

  • 2007년 10월 11일, 한강일대를 오가는 관광 및 출퇴근 용도의 수상택시가 운항을 시작하였다. 그러나 서울의 교통난을 해결할 수 있을 것이라는 기대와는 달리 경제성, 접근성과 관련된 문제로 인해 이용이 활성화 되지 못하고 있는 실정이다. 따라서 본 연구에서는 대중교통관련 선행연구고찰을 토대로 수상택시 서비스 평가 항목을 개발한 후, 이용자 만족도 설문조사, 중요도-만족도 분석(IPA: Importance Performance Analysis)을 통하여 현재 제공되고 있는 수상택시 서비스에 대한 이용자 측면의 서비스 특성을 분석하고, 이에 대한 시사점을 제시한다. 종합적인 서비스 측면의 IPA 결과, 첫째, 중점개선항목으로 경제성에 대한 부분이 나타났다. 둘째, 개선요망항목으로 접근성, 정보성, 편리성, 현상유지 항목으로 나타났으며, 안전성과 정시성은 노력지속 항목으로 평가되었다. 셋째, 현상유지 항목으로는 친절성과 쾌적성으로 나타났다. 이러한 종합적인 측면의 결과를 바탕으로 수상택시 이용자의 서비스특성을 판단해 보면, 이용자의 경제적 부담에 대한 부분이 가장 시급한 것으로 나타났다. 접근성 즉, 연계교통수단에 대한 부분과 수상택시를 이용할 수 있는 표지판 및 편리성에 대한 부분이 개선되어야 하는 것으로 나타났다. 분석결과를 종합하여 투자우선순위 선정시 한정된 예산을 바탕으로 경제성, 접근성, 정보성, 편리성을 시급히 개선해 준다면 이용활성화에 어느 정도 기여가 가능할 것이라 판단된다.
