Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

Purpose: This study questioned the efficiency of daylight factor as a daylight adequacy and investigated a method of how to complement its weakness by considering a direct sunlight component under a clear sky condition. Method: The Snowdon visitor centre cafe was chosen as a case study building and various techniques such as BRE formula, BRE sky protractor, Pilkington dot diagram and mock-upscale model under the artificial sky simulator were used to analyse and compare daylight factor values. An analysis of direct sunlight component under the clear sky condition was carried out by Climate Consultant 5.5, sun path diagram, and the artificial sky simulator. Result: The result of daylight factor analysis differed by the adopted techniques and it was also contradictory to the results on a direct sunlight penetration. The result not only showed the limitation of daylight factor as a metric but also suggested an improvement by combining it with direct sunlight analysis. The techniques used in this study had a merit of being applied in the early design stage and thus be beneficial to many design professions in order for early daylight performance analysis.

Owing to a landslide or embankment damage be caused by a localized torrential downpour and heavy snowfall resulted from recent abnormal climate, a slope stability is very important. This study is investigate a general slope reinforcement method and applicability improvement of soil nailing method utilized prototype loading test for the facing stiffness effect confirmation. A prototype loading test supplements general slope stability study by numerical analysis or laboratory test with a resonable analysis of slope structure.

본 연구에서는 미래 기후변화로 인한 미래 홍수의 불확실성을 고려하여 영산강유역 종합치수계획 보고서(MLTM, 2005)에서 제시한 4가지 홍수방어대안들을 재평가하였다. 불확실성을 반영하기 위해 미래 RCP 기후 시나리오에 따른 확률강우량 값의 변화, 홍수의 시간적 분포, 그리고 공간적 분포 등 세가지 불확실성 요소를 고려하였다. 이 요소들의 조합을 통해 각기 다른 특성을 갖는 216개의 홍수 시나리오가 생성되었으며 생성된 홍수 시나리오 하에서 대안들의 수행능력이 평가되었다. 평가 결과를 통해 4개의 대안들 중 가장 로버스트한(혹은 강건한) 대안이 선별되었다. 또한, 불확실성 요소 평가를 통해 대안들이 좋지 못한 수행능력을 보이게 하는 주 원인 요소를 파악하였다. 이러한 정보는 의사결정자에게 대안들에 대한 더 상세한 통찰력을 제공하며 이후 선정한 대안의 로버스트함을 증대시키는데 있어 중요한 단서로 활용될 수 있다.

The objective of this study is to analyze the characteristic of radiation environment in the urban and rural through the field observation in the summer. The radiation balance was compared through the measurement of the shortwave radiation and long-wave radiation in the urban, sub-urban, and rural. The following conclusion could be obtained from this research. (1) In the results of observation including the rain-day, it was found that the short wave radiance in the urban is lower about 10% than the rural. (2) The upper part of atmosphere layers in the urban area absorb much short wave radiation energies compared with the rural relatively. It can increase the temperature of the upper part of atmosphere layers and the emittance of long wave radiation. (3) The ratio of the downward short wave radiation to the downward long wave radiation was 1.24 for the urban, 1.28 for sub-urban and1.35 for rural. It can be estimated that the atmosphere condition of the rural is better than that of other areas.

The study aims to investigates and explore the quality of work life (QWL) and also to find out which QWL factors are considered as primary factors among employees of PT. Duta Transformasi Insani, a consulting service management in Indonesia. The factors of QWL in this study consist of nine components, which are: work environment, organizational culture and climate, relation and cooperation, training and development, reward and compensation, facilities, job satisfaction and job security, work autonomy, and resource adequacy. This study conducted a survey of every employee who works for PT. Duta Insani, which consists of various sample characteristics, such as gender, education level, and length of employment. The descriptive analysis also analyzes how the QWL condition in this company. The method in this research using quantitative descriptive and factor analysis, together with validity and reliability tests, to fulfill the study objectives.

기후변화로 인해 물의 증발량이 많은 지역의 지반에서는 자연적인 소금의 고결화 현상이 발생한다. 이러한 소금의 고결화 분포는 모래지반에서 모세관력에 영향을 받는다. 이 연구의 목적은 콘 관입시험, 전기전도율 측정, 사진 이미지 촬영, 비파괴 이미지 분석 그리고 탄성파에 의한 프로세스 모니터링을 이용하여 소금의 고결화 현상에 대한 모세관력의 효과를 관찰하는 것이다. 실험은 입상재료를 모형화한 글라스비즈를 소금물에 포화시킨 후, 오븐에 넣어 시료를 건조시킴으로써 고결화를 발생시켰다. 실험결과, 고결된 소금의 농도는 시료입경이 작은 경우 최상부에서 높았고, 시료입경이 큰 경우 중간 또는 하부에서 높았다. 고결된 시료에서 높은 소금농도의 위치는 해석적 방법으로 산정된 모세관 높이와 유사하였다. 본 연구에서 수행한 5가지 실험은 모세관력이 소금이 고결된 흙과 같은 입상재료의 거동에 중요한 영향을 끼치는 것을 보여준다.
