This study was conducted to identify the attitude of ethical dilemmas in hospital nurses. Ethical dilemmas were categorized into four areas : human life area, clients area, nursing practice area, and nurses-co-worker area. 354 nurses working in clinical settings were selected in Seoul and Kangwon area. Data were gathered from 26, June to 10, July, 1994 by structured guestionnaires. Descriptive statistics were employed to analyze the data. The results obtained from data were as follows : 1) In human life area mean score was 3.03. This area showed remarkabale individual differences between utilitarian and deontological position. 2) In clients area mean score was 3.94. It means that nurses tend to take a deontological position. 3) In nursing practice area mean score was 3.41. It means that nurses tend to take a slightly deontological position. 4) In nurses-co-worker area mean score was 3.88. It means that nurses tend to take a deontological position. To conclude, clinents area, nursing practice area, and nurses-co-worker area taken deontological position. Most nurse's primary concern was the 'welfare of the patients' which is to fundamental ethical professional practice. But nurses experienced more ethical dilemmas in human life area than others. Therefore, nurses should be prepared to make in-dependent decision that based on bio-ethics and professional ethics.

The purpose of this study is to suggest a guideline for outdoor play settings in child care centers. From March to July, 2005, data were collected from 223 directors at child care centers through a structured questionnaire, field measurement survey and non-participatory observation in seventeen child care centers in Seoul and Daejeon. The statistical methods for analysing data were frequency, percentage, mean, $X^2$ and F-test. The results showed as follows: 1)the existing outdoor playground area in child care centers should be expanded more than $4\;m^2$ per child. 2) Outdoor play facilities should be equipped with two structured play sets, a play facility for unstructured play and an adventure facility to make child's various activities possible and to promote child development. 3)flooring materials for outdoor playground should be required to use more than three kinds such as solid coverings (cf. asphalt, standard concrete), wood, lawn, soil or sands. 4)to let children enjoy various activities, outdoor playground area should be composed of various play facilities like indoor play gyms and should be independent but have good connections between play facilities depending on characteristics of play activities. 5)Play spaces of outdoor playground should be composed of physical play space, unstructured and dramatized play space, rest space, space for nature and adventure space. In addition, appropriate play equipments should be provided in respective play space.

NDVI (Normalized Difference Vegetation Index) plays an important role in surface land cover classification and LST (Land Surface Temperature Extraction). Its characteristics do not full carry the information of the surface cover typically in urban areas even though it is widely used in analyses in urban areas as well as in vegetation. However, abnormal NDVI values are frequently found in urban areas. We, therefore, examined NDVI values on whether NDVI is appropriate for LST and whether there are considerations in NDVI analysis typically in urban areas because NDVI is strongly related to the surface emissivity calculation. For the study, we observed the influence of the surface settings (i.e., geometric shape and color) on NDVI values in urban area and transition features between three land cover types, vegetation, urban materials, and water. Interestingly, there were many abnormal NDVI values systematically derived by the surface settings and they might influence on NDVI and eventually LST. Also, there were distinguishable transitions based on the mixture of three surface materials. A transition scenario was described that there are three transition types of mixture (urban material-vegetation, urban material-water, and vegetation-water) based on the relationship of NDVI and LST even though they are widely distributed.

The changes of rural landscape are currently spread everywhere and are rapidily being processed both in quality and in quantities of changes From such aspects, it is urgent to control the land scape change, and is required to know what is valued or preferred in rural landscape, This study was conducted to investigate preferences and differences of the responses between urban and rural residents to rural scenery. As a method, color-slide surrogates for rural landscape settings are shown to urban and rural residents, For a given 52 scenes of rural landscapes the respondents judged the familiarity, orality, and preference along a ten point scale. The following facts are found: 1) Refponses to certain types of landscape settings are influenced by the place of residence of the respondents. The urban residents highly rated natural components of the rural landscape. In contrast rural residents preferred the scenes with visible sign of development 2) The relations among the estimation of preference, familiarity and rurality in rural landscape were deeply correlated. When the rural lands(:ape is adequately ref resented as 'familiarity' or 'rurality' well the landscape is more preferred 3) It is found what is valued or preferred in rural landscape : Readjusted agricultural land, big tree, grassland hi dominated visually were preferred in rural landscape. The implication of this study is that successful planning of development or management in rural area will occur only when these different needs and values are acknowledged and accommodated.

The purposes of the present study are to describe the design of mobile learning scenarios based on learning sciences theories, and to discuss implications for the future research in this area. To move beyond mere speculations about the abundant possibilities of mobile learning and to make real impact in K-12 school settings, it is critical to conduct school-based research grounded on the learning sciences theories. Towards this end, this paper describes school-based mobile learning projects conducted by a research team at the Learning Sciences Lab in Singapore, and then discusses the possibilities and challenges of mobile learning to further inform future research. Specifically, this paper explores the affordances of mobile technology, such as portability, connectivity and context-sensitivity, to design seamless learning scenarios that bridge formal and informal learning experiences. The authors present a framework for re-conceptualizing different types of learning based on physical settings and intentionality, and then describe two seamless learning scenarios, namely 3Rs and Chinatown Trail, which were implemented in one primary school in Singapore. In conclusion, the authors discuss the affordances of seamless mobile learning for enhancing one's lived experiences to build a living ecological relationship between the person and the environment, and how mobile technology can play a critical role for enabling such lived experiences.

The Qualitative improvements of outdoor spaces are unsatisfactory in comparison with that of indoor environment in existing apartments. Lately construction companies are differentiating the outdoor spaces of apartment complexes to meet needs of residents. However, high-rise buildings inherently have limitations on providing exposure to the outdoor settings and inappropriate lightings could have serious impacts on physical and psychological health of residents. Therefore, the purpose of this study is to provide useful information for the luminous environment of outdoor spaces through the analysis of current apartment complexes' lighting plans. Outdoor space of branded apartment complexes in Seoul, built after the year 2003, were researched. Through site visits, illumination level and lighting plans were investigated classified into entry area, passage area, plaza, rest area, exercise area, and play area. With the result, illumination level of apartment complexes researched was lower than KS illumination standard in all areas and the lighting plans were mostly shown in different condition of first intended lighting plan because of insufficiency of maintenance in lighting system. Therefore, it is need to provide better luminous environment to make outdoor space more lively and energetic at the night time.

In order to facilitate the electricity market operation and trade in the restructured environment, ample transmission capability should be provided to satisfy the demand of increasing power transactions. The conflict of this requirement and the restrictions on the transmission expansion in the restructured electricity market has motivated the development of methodologies to enhance the available transfer capability (ATC) of existing transmission grids. The insertion of flexible AC transmission System (FACTS) devices in electrical systems seems to be a promising strategy to enhance single area ATC and multi-area ATC. In this paper, the viability and technical merits of boosting single area ATC and multi-area ATC using Thyristor controlled series compensator (TCSC), static VAR compensator (SVC) and unified power flow controller (UPFC) in single device and multi-type three similar and different device combinations are analyzed. Particle swarm optimization (PSO) algorithm is employed to obtain the optimal settings of FACTS devices. The installation cost is also calculated. The study has been carried out on IEEE 30 bus and IEEE 118 bus systems for the selected bilateral, multilateral and area wise transactions.

In San Francisco, two new museums were recently built in 1995 and 2005. The one is San Francisco Museum of Modern Art designed by Mario Botta and the other is De Young Museum designed by Jacques Herzog & Pierre de Meuron. The urban settings for the museums are compared with each other and theories of the architects are evolved on different branches in the modernist trends. The theories and settings are followed by the representation in the forms, facades, interior spaces and towers. SFMOMA is located on the SoMa area, which was recently developed into a cultural urban core with Moscone Center and Buena Yerba Garden. De Young Museum was rebuilt in the old museum site in the Golden Gate Park. The one is on the context of urban artefacts and the other on the context of natural artefacts. To Botta, the museum in today's city plays a role analogous to that of the cathedral of yesterday. It is a place of common encounter and confrontation. The volume of SFMOMA which is geometrical and symmetric with double pylons. The frontality on the street and public green open space and the axiality of SFMOMA runs through the Buena Yerba Garden over Buena Yerba Center for the Arts are reminded us of an urban core with a religious monument and a city square. The staircase with grandiose design in the atrium seems to work as an altar with lighting from skylight above enhancing the liturgical ambiance. De Young Museum is shaped in a rectangle with long narrow courtyards. Three bands of volumes are juxtaposed and the nature flows into the museum corridors and galleries. The tower is distorted so as to be aligned to the street grids of the surrounding area. The copper panel of De Young Museum and natural context evoke modern concept of "machine in the garden". The two museums from different pedigrees of Modern Architecture are now major landmarks of SF and urban expressions for the 21st century.
