Recently, new concept and paradigm of 'Environmentally-Friendless' is taking a growing interest in environmental planning and design. This study is to develop the new approach of sustainable development, and to establish the indicators for environmentally-friendliness of "Tourism Farms" in rural areas. A questionnaire survey was conducted for deputy manager group and expert group. The environmentally-friendliness of tourism farms is composed of three categories, conservation of global environment(Low Impact), friendliness to surrounding nature(High Contact), and environmental health and amenities (Health '||'&'||' Amenity). Four indicators, such as saving of energy and water resource, reduction and reuse of garbage, natural purification of sewage disposal, and utilization of natural energy, were affecting the first category, i.e., conservation of global environment(Low Impact). And, friendliness to surrounding nature (High Contact) is affected by 3 indicators, such as contact to nature and diverse green areas, water intimate '||'&'||' contact areas, and natural ecology observation by biotope. Finally, the dimension of environmental health and amenity is affected by 3 indicators, such as nature affinity by farming experience, environmental-friendliness of soil '||'&'||' crops by organic farming, campaign and education programs of environmentally-friendliness. From the result of Importance-Performance Analysis(IPA) for 10 indicators, environmentally-friendliness was recommended as 'Concentrate Here'. And, the content validity of 10 indicators for 3 categories was examined by factor analysis. The result showed as the same as hypothetical model, which proved the validity of hypothetical model.

Purpose: This study was to identify the level of job stress and turnover intention and to explore the impact of job stress on turnover intention among emergency room (ER) nurses. Methods: With a correlational survey design, 155 emergency room nurses were recruited in D metropolitan city. Data were collected using a structured questionnaire including ER-related job stress, turnover intention, and subjects' characteristics from March 18 to March 26, 2013. Results: Overall mean score of job stress was $284.34{\pm}40.60$, indicating higher level of job stress. The highest job stress category was conflict related inside the hospital and transportation team, and followed by matters related the patient and the guardian, conflicts with doctors, and heavy workload. The average score of turnover intention was $15.41{\pm}3.68$, indicating higher intention to quit their jobs. There was a moderate level of positive correlation between job stress and turnover intention (r=.44, p<.001). Turnover intention was high when ER nurses had higher job stress (${\beta}$=.38), were female (${\beta}$=.22), and wished to move to another department (${\beta}$=.17). Conclusion: The most important factor of turnover intention was job stress among ER nurses. Strategies to lower turnover rate for ER nurses should be focused on seeking ways to reduce their job stress.

Purpose: Retention and infiltration of small and frequently-occurring rainfall by LID facilities account for a large proportion of the annual precipitation volume. Based on 4 standard facilities such as Porous Pavement, Infiltration Trench, Cylindrical Infiltration Well, Rectangular Infiltration Well by Seoul Metropolitan Handbook of the Prior Consultation for LID. The total retention volume of each facility was calculated according to the type and size. The Purpose of this study is to find out the quantitative relationship between Percentile Rainfall Event and Design Volume of Infiltration Facilities. Methode: For the estimation of Percentile Rainfall Event, Daily Precipitation of Seoul from 2005 to 2014 was sorted ascending and the distribution of percentile was estimated by PERCENTILE spreadsheet function. The managed Rainfall Depth and Percentile of each facility was calculated at the several sizes. In response to the rainwater charge volume of 5.5mm/hr by the Category "Private large site", the 3 types of facilities were planned for example. The calculated Rainfall Depth and Percentile were 54.4mm and 90% by the use of developed Calculation-Module based on the Spreadsheet program. Result: With this Module the existing Designed Infiltration volume which was introduced from Japan was simply converted to the Percentile-Rainfall-Event used in USA.

Future climate according to land-use change was simulated by regional climate model. The goal of study was to predict the distribution of meteorological elements using the Weather Research & Forecasting Model (WRF). The KME (Korea Ministry of Environment) medium-category land-use classification was used as dominant vegetation types. Meteorological modeling requires higher and more sophisticated land-use and initialization data. The WRF model simulations with HyTAG land-use indicated certain change in potential vegetation distribution in the future (2086-2088). Compared to the past (1986-1988) distribution, coniferous forest area was decreased in metropolitan and areas with complex terrain. The research shows a possibility to simulate regional climate with high resolution. As a result, the future climate was predicted to $4.5^{\circ}$ which was $0.5^{\circ}$ higher than prediction by Meteorological Administration. To improve future prediction of regional area, regional climate model with HyTAG as well as high resolution initial values such as urban growth and CO2 flux simulation would be desirable.

Sleep is an essential physiological process, especially for proper brain function through the formation of new pathways and processing information and cognition. Therefore, when sleep is insufficient, this can result in pathophysiologic conditions. Sleep deficiency is a risk factor for various conditions, including dementia, diabetes, and obesity. Recent studies have shown that there are differences in the prevalence of sleep disorders between genders. Insomnia, the most common type of sleep disorder, has been reported to have a higher incidence in females than in males. However, sex/gender differences in other sleep disorder subtypes are not thoroughly understood. Currently, increasing evidence suggests that gender issues should be considered important when prescribing medicine. Therefore, an investigation of the gender-dependent differences in sleep disorders is required. In this review, we first describe sex/gender differences not only in the prevalence of sleep disorders by category but in the efficacy of sleep medications. In addition, we summarize sex/gender differences in the impact of sleep disorders on incident dementia. This may help understand gender-dependent pathogenesis of sleep disorders and develop therapeutic strategies in men and women.

환경문제에 대한 인식의 확산과 함께 건설산업에서도 건축물로 인한 환경영향을 저감하고자 하는 연구가 수행되었으나, 대부분의 연구는 이산화탄소에 집중되어 왔다. 하지만, 이산화탄소로 대표되는 지구온난화 뿐만 아니라 다양한 환경영향이 존재하며, 해외에서는 이러한 환경영향에 대한 포괄적인 분석이 적극적으로 시행되고 있다. 이에 따라, 본 연구에서는 건축물로 인한 환경영향을 보다 포괄적으로 평가할 수 있도록, 6가지의 환경영향 범주를 정의하였다. 즉, 지구온난화, 오존층파괴, 자원고갈, 산성화, 부영양화, 광화학산화를 환경영향 범주로 정의하고, 평가 기준들을 제시하였다. 그리고 본 연구에서 제시한 환경영향 범주에 대한 평가의 필요성을 검토하기 위하여 2가지 비교 설계안을 대상으로 사례분석을 시행한 결과, 지구온난화만을 평가한 것과는 상이한 결과가 도출되었다. 즉, 이산화탄소로 대표되는 지구온난화 지수를 기준으로 비교하면 2안이 우수한 것으로 판단되었지만, 6가지 영향범주 모두를 평가한 결과에서는 1안이 우수하다는 결과가 도출되었다. 이는 지구온난화 뿐만 아니라 다양한 환경영향을 포함하여 평가하는 것이 보다 타당한 결과 도출을 유도할 수 있다는 것을 의미한다. 따라서 건축물에 대한 환경영향을 평가하기 위하여, 본 연구에서 제시한 6가지 환경영향 범주를 사용한다면, 보다 타당한 결과의 도출이 가능할 것이라 판단된다.
