Currently, the energy consumption of electric lighting in an office building is accounted for more than 30% of the total energy consumption. In order to reduce the energy consumed by the indoor lighting, the daylight as a natural energy resource can play an important role in energy savings. The daylight can have positive impacts on improvement of work; efficiency and productivity, and also make people feel more psychologically stable. Moreover, by using the daylight, we can definitely reduce the energy consumption in office buildings. Thus, the purpose of this study is to determine the LED dimming ratio depending on the ratio by calculating the amount of artificial illumination required according to the change of daylight by using the light simulation software that can quantify and visualize the performance of daylight. As a result, the energy savings could be obtained up to 30%.

In the normal office building, the energy consumption to maintain the reasonable intensity of illumination for the work by using the artificial illumination occupies 30% or greater of the whole building electricen ergy consumption. If the depend ability of the artificial illumination is dropt by positively using the natural lighting from the outside, the large amount of electrical energy can be saved, in addition the more nice visual environment for work can be created. Daylight is lighting source that most closely match visual response of the human, because sunlight and skylight achieve the harmony. For this reason, the daylight of small amount than amount of the artificial lighting source also can give the same effect in work activities of human. In addition, if there is daylight at the window of the building, the energy can be saved by controlling the artificial lighting. In this paper, in the building using the photovoltaic power generation analyze the correlation between the amount of energy generated by photo voltaicand indoor illumination and this was proved through the simulation with Relux 2010. In addition, the amount of daylight inflow in the room and distribution was drawn by the equation and the ratio for the sectional dimming control of each lighting equipment was predicted and the energy saving amount according to this was calculated. As are sult, the indoor illumination was satisfied with recommended illumination value of the office and consumption power could be reduced approximately with 20∼70%.

본 연구에서는 Rogers의 이론 및 기존 선행연구결과를 바탕으로, 성인애착 불안과 이성관계 만족 간의 관계에서 관계진솔성과 보살핌의 다중매개효과와 성인애착 회피와 이성관계만족 간의 관계에서 관계진솔성과 보살핌의 다중매개효과를 검증하였다. 연구를 위해 제주도를 제외한 전국의 연애경험이 있는 20대 미혼 성인 남녀 305명을 대상으로 한국문화에 맞게 타당화된 성인애착 척도, 관계진솔성 척도, 보살핌 척도, 이성관계만족 척도를 사용하여 설문조사를 실시하였다. SPSS 21.0과 Process Macro v 3.4를 사용하여 자료를 분석하고, 간접효과 검증을 위한 부트스트래핑을 실시하였다. 분석 결과 성인애착 불안과 이성관계만족 간 관계에서 관계진솔성과 보살핌의 부분매개효과가 유의하였고, 성인애착 회피와 이성관계만족 간 관계에서 관계진솔성과 보살핌의 부분매개효과가 유의하였다. 또한 성인애착 불안과 성인애착 회피 모두 관계진솔성과 보살핌을 순차적으로 매개하여 이성관계만족에 영향을 미치는 것으로 나타나 관계진솔성과 보살핌의 다중매개효과가 입증되었다. 본 연구 결과를 바탕으로 살펴본 논의, 이론적 및 실제적 시사점과 의의, 연구의 제한점과 후속연구에 대한 제언을 기술하였다. The present study examined the multi-mediating effects of relationship authenticity and caregiving on the link between adult anxiety attachment and heterosexual relationship and between adult avoidant attachment and heterosexual relationship satisfaction by analyzing responses from 305 people in their 20s nationwide using Process Macro v 3.4. As a result of the analysis, the partial mediating effect of relationship authenticity and caring was significant in the relationship between attachment anxiety and heterosexual satisfaction, and the partial mediating effect of relationship honesty and caring in the relationship between attachment avoidance and heterosexual satisfaction was significant. In addition, both attachment anxiety and attachment avoidance sequentially mediate relationship authenticity and caring to influence heterosexual satisfaction, proving the multi-mediating effect of relationship authenticity and caring. Implications, limitations, and suggestions for further research are discussed.
