This study was carried out in order to establish the estimation equation for school power consumption using regression analysis based on collected power consumption for two years of weather data and schools are located in Central Changwon and Masan district in Changwon city. (1) The power consumption estimation equation for Heating and cooling is calculated using power consumption per unit volume, the difference between actual power consumption and results of estimation equations is 4.1%. (2) The power consumption estimation equation for heating load is showed 2.6% difference compared to actual power consumption in Central Changwon and is expressed 2.9% difference compared to that in Masan district. Therefore, the power consumption prediction for each school using the power consumption estimation equation is possible. (3) The power consumption estimation equation for cooling load is showed 8.0% difference compared to actual power consumption in Central Changwon and is expressed 2.9% compared to that in Masan district. As the power consumption estimation equation for cooling load is expressed difference compared to heating load, it needs to investigate influence for cooling load.

초저속 동영상 부호화에서 블록화 현상을 해결하기 위해 affine 변환을 이용한 움직임 보상 방법이 제안되었고 움직임 추정에서 정밀한 움직임 추정하기 위해 육각형 정합 알고리듬이 제안되었다. Affine 변환에서 영상을 삼각형 조각들로 나눌 때 삼각형 형태와 물체가 불일치할수록 보상 영상의 예측 에러가 증가하고 일그러짐 현상이 나타난다. 본 논문에서는 이러한 문제점을 해결하기 위해 영상의 윤곽 정보에 따라 다른 형태의 삼각형 조각들로 나누고, 또한 윤곽 정보가 복잡한 부분은 삼각형을 세분화하는 알고리듬을 제안한다. 제안한 방법에서 정밀한 움직밍 벡터를 추정할 때 이웃하는 삼각형 조각 형태 차이로 인하여 다각형 정합 알고리듬을 제안하고 H.263과 성능르 비교한다. Motion compensation by affine transform has been proposed as a solution to the artifact problems in very low bit rate video coding and a HMA(Hexagoanl Matching Algorithm) has been proposed for refine motions estimation. When dividing images with an affine transform, as image objects do not necessarily conform to triangle patterns. In this paper we propose a method that first divides an image into triangular patches according to its edge information and then further divides the image into more detailed triangular patches where more complicated edge information occurs. We image propose a PMA(Polygona Matching Algorithm) for refine motion estimation because of the different triangle pattern types of neighboring blocks and its performance is compared with H.263.

As the recognition of the society about an eco-friendly system gradually become growing, the green building certification has been started from 2006 and an improvement of applying the standard of certification has been pointed out constantly. Comparing with the revised standard of July 2010, the reliability of the certification is raised and an appraisal standard of the field of the energy is tightened. The acquired average score in the energy field concerning the appraisal article analysis of a reference school become low relatively. But the acquired score of the EPI has large difference between the appraisal articles. Therefore, research on decreasing of these differences should continue.

박효석(Park, Hyo-seok),오규식(Oh, Kyushik),이상헌(Lee, Sangheon) 한국도시행정학회 2014 도시 행정 학보 Vol.27 No.4

기후변화의 근본 원인인 온실가스 발생을 저감하기 위한 노력이 국제적으로 이루어지고 있다. 대표적인 예로 대체에너지의 개발 및 사용, 에너지 사용효율을 높이거나 에너지 사용을 최소화하는 것과 같이, 인간생활에 직접적인 변화를 주는 대안들이 주로 거론되고 적용하기 위한 노력이 진행되고 있다. 이에 반해, 그린인프라를 통한 이산화탄소의 저감은 인간활동에 대한 변화가 수반되지 않으면서 동시에 이산화탄소의 흡수가 가능한 방법으로, 기후변화에 대응할 수 있을 뿐만 아니라 녹지를 통한 어메니티의 증진까지 함께 꾀할 수 있다. 이에 본 연구에서는 서울시를 대상으로 신규로 도입이 가능한 그린인프라 유형을 선정하고, 그린인프라를 확충했을 시 이산화탄소의 흡수량이 얼마나 증진될지에 대해 연구를 진행하였다. 기존 그린인프라와 신규로 추가된 그린인프라 요소를 모두 포함하여 분석한 결과, 그린인프라를 통한 이산화탄소의 흡수량은 약 2.2% 증가하였으며, 지역적으로는 주로 넓은 면적의 산림이 포함되는 서울 외곽의 자치구들이 높은 이산화탄소 흡수량을 보인 반면, 도시 내부에 위치한 자치구들은 그린인프라를 통한 이산화탄소의 흡수량이 현저히 낮게 나타남을 알 수 있었다. 따라서 이산화탄소 흡수량이 낮게 나타나는 자치구들에서는 새로운 유형의 그린인프라를 도입을 통해 그린인프라를 확충함과 동시에, 수목밀도의 증가, 수종의 변경 등과 같이 기존 그린인프라의 질적인 구성을 향상시키려는 노력이 필요하다. There have been a number of efforts to reduce the emission of GHGs(Green House Gases) which is the fundamental cause of climate change. However, there are limitation to adopt the representative measures including alternative energy sources development, the energy efficiency improvement of products and energy use minimization, because those change and regulate the human life style. On the other hand, the absorption of CO₂ by green infrastructure can not only cope with the climate change but also enhance the amenity without the change of life style. Therefore, the effect of green infrastructure on CO₂ absorption is analysed in this study. The CO₂ absorption of newly adopted green infrastructure increases 2.2%, and the outskirt areas where are huge mountains show remarkable CO₂ absorption than the areas inside of Seoul. It means that the areas inside of Seoul need to introduce new type of green infrastructure and improve the quality by changing the species and increasing the density of trees to respond to the climate change more efficiently.

The purpose of this research is to discover the structural relationship between self-esteem, exercise commitment, and psychological happiness in order to provide fundamental data for the study using psychological variables, to improve the efficiency of Taekwondo training program, and to contribute on the enhancement of Taekwondo players" satisfaction and their performance. The subject of this study is 366 Taekwondo players participated in University Taekwondo Championship in April and May of 2012, hosted by Korea University Taekwondo Federation. Data has been analyzed with SPSS(17.0 version) and AMOS(18.0 version) program. The following discoveries have been found through this research. First, positive self-esteem had positive and meaningful influence on both cognitive commitment and behavioral commitment of exercise commitment while negative self-esteem gave negative and meaningful effect on cognitive commitment of exercise commitment. Second, positive self-esteem showed positive and meaningful effect on self-confidence and commitment while it did not affect on self-realization and pleasure. However, negative self-esteem gave negative and meaningful influence on self-realization and commitment while it did not affect on self-confidence and pleasure. Third, both cognitive commitment and behavioral commitment of exercise commitment showed positive and meaningful correlation with all the aspect of psychological happiness. Fourth, in terms of the relationship between self-esteem, exercise commitment, and psychological happiness, positive self-esteem had positive correlation with all the aspect of psychological happiness through exercise commitment. Such results present that Taekwondo players tend to concentrate more on the exercise and be more psychologically happy if they had greater and more positive self-esteem. Thus, Taekwondo instructors in the university team should not only put their effort on the way to improve players" Taekwondo skills. They should also endeavor to discover the way to enhance players" positive self-esteem in order for them to be more concentrated on their exercise.

대학 태권도 선수의 운동스트레스가 중도탈락의도 및 운동지속수행력에 미치는 영향

박효석(Park, Hyo-Seok),김공(Kim, Kong) 한국체육과학회 2012 한국체육과학회지 Vol.21 No.1

The purpose of this study is to analyze how the sport stress of university Taekwondo players influences their dropout intention and exercise adherence. A total of 201 Taekwondo players participated National Taekwondo Championship in June 2011 and ational Athletes Selection Competition for 26th Summer Universiad. We used questionnaires in this study comprised of questions identifying demographic characteristics of players, their sport stress, dropout intention, and exercise adherence in scale. We have selected samples with random sampling method, and used elf-administration method to fill out questionnaires. We have conducted frequency analysis, exploratory factor analysis, Pearson’s correlation analysis, and multiple regression analysis on collected data with SPSS Will Ver. 17.0 program. This study has shown the following results. First, we have discovered meaningful positive relationship between sport stress factors and dropout intention factors. It was not much different between sport stress factors and exercise adherence factors. However, we could see the considerable negative relationship between one of sport stress factors called as the restriction of time, and predisposing and enabling, components of exercise adherence. We have also found out meaningful negative relationship between dropout intention factors and exercise adherence. Second, statistics implied that the restriction of time has proportionally affected to causal and environmental factors of dropout intention, and inversely affected to predisposing factor. Functional instability, a component of sports stress, gives a meaningful and negative impact on the environmental factor of dropout intention. Third, environmental factors of dropout intention were negatively related with predisposing, enabling, and reinforcing, factors of exercise adherence. Causal factors of dropout intention was also inversely affected the reinforcing factor of exercise adherence. These results show that we must control sports-related stress factors to prevent dropouts of university Taekwondo players and help them to exercise continuously. They also deliver messages to us that we should help in finding ways for athletes to appropriately deal with environmental factors such as academic achievements, financial difficulties, anxiety about the uncertain future, and excessive training.

2003년 대구지하철화재를 보면 각종 대형 화재사고에서 법정 피난유도(유도등, 조명등)만으로는 화재 시 발생하는 연기 및 정전에 의하여 피난방향을 유도할 수 없음이 증명되었으며, 건축 계획적 측면에서의 안전을 확보하였다 하더라도 비상시 유도 설비들이 유도성능을 제대로 발휘하지 못 할 경우에 화재 상황으로부터 피난의 위험성을 가지고 있다고 할 수 있다. 따라서 소방 설비의 의존이 필요치 않은 자체적인 발광이 가능한 축광 안전용품이 필요시 하게 되었으며, 이에 현재 사용하고 있는 기존의 축광제품은 휘도가 떨어져 사실상 그 효과가 미미하며, 이 문제점을 해결하고자 지속발광 가능한 축광소재를 개발 하고자 한다.
