It shows that a variety of side effects result from the housing-supply policy focused in quantity. In a rental apartment for the low-income group, a shortage of maintenance cost in facilities become aggravated. The rapid progress of obsolete leads the lessor to the economic loss as well as a baneful influence to national economy. Also, the maintenance skill brings inadequacy by reason of technique development focused on new construction. As a result, the cost which needs for maintenance should get accomplished to application toward economy analysis and attempt considered management and financial affairs. Simultaneously, it should keep and administer a lot of data of maintenance affairs during life cycle in apartment and set up the way for aiding the situation of maintenance process.

Purpose: This descriptive study was done to identify the rate of repeated falls in hospitalized elders and characteristics related to the falls, as well as characteristics of fractures resulting from falls. Method: Using a check list designed by the researchers, data were collected from October 15 to October 25. 2007 in a hospital in Seoul by examining the medical records of all elders. 65 years or older who sustained fractures from falls and were admitted to the hospital during the period from July, 1, 2006 to June 30. 2007. Frequency, percentage, mean, and x² with the SPSS 12 were used to analyze the data. Result : Of the demographic characteristic, economic status, and of the physical characteristics, vision and hearing showed highly significant relationships to repeated falls (p<.05). But the other demographic, physical, and environmental characteristics were less significant. The rate of repeated fall for the elders was 37.5% and the rate of fractures as a result of falls was 61.9%. Conclusion : To prevent falls in elders and thus improve the quality of their lives, nurses should focus on physical and economic status of elders.

패턴의 선폭이 100nm이하로 작아짐에 따라 패턴이 부러지고, 휘고, 떨어져 나가는 현상이 발생하는데 이러한 현상을 패턴 붕괴 현상이라고 하며, 반도체 생산과 수율에 많은 영향을 미친다. 패턴 붕괴 현상은 리소그래피 과정 중 현상 후 세척액을 건조하는 과정에서 주로 발생하며 세척액의 표면장력에 의한 모세관 현상이 주된 원인으로 알려져 있다. 패턴 붕괴 현상을 시뮬레이션하기 위하여 패턴이 세척액에 의해서 균일한 압력을 받을 때와 집중 압력을 받을 때의 역학적 모델을 세우기 각각의 모델을 통하여 선폭과 패턴간의 거리에 따른 임계 높이/선폭비 (aspect ratio) 를 계산하여 실제 실험 결과와 일치하는 모델을 선정하였다. 또한 패턴 내부에 생기는 stress 에 의한 부러짐 현상과 패턴 과 레지스트 패턴 하부 층 사이의 접착력 부족으로 발생하는 떨어짐 현상을 해석하였다. High aspect ratio resist patterns with dimensions below 100 nm often bend, break or tear. These phenomena are generically called "resist pattern collapse". Pattern collapse is a very serious problem in fine patterning of less than 100 nm critical dimension (CD), so that it decreases the yield. In order to mechanically analyze this phenomenon and create its simulator, two models have been made and compared. In this paper, various approaches with various analyses are made to understand pattern collapse. Also, the critical aspect ratio for 100 nm node, that determines whether pattern collapse happens or not, can be calculated with these approaches. Finally, tear type caused by insufficiency of adhesion strength between the substrate and the resist is analyzed with a point of view of the surface free energy.

The purpose of this research is to compare and analyze the physical self-efficiency and physical education satisfaction due to existence of new sports physical education class, and school life adaptation. Also by systematically analyzing the relationship of cause factors, we will understand the primary affecting cause due to attending physical education. Moreover by effectiveness proof close examination of new sports in physical education, we wish to help in creating healthy leisure culture for teenagers to develop mentality and provide foundation for life-time physical education activities. In order to achieve this goal, this research tested one middle school which practices new sports physical education program and two middle schools which practices regular physical education. 3 classes from each school, total of 9 classes have been tested and 302 questionnaire papers were passed out. Out of these papers, 294 papers were valid after material arrangement, and have been final analyzed. With above research purpose and method as basis, hypothesis about the affect physical self-efficiency and physical education satisfaction of middle school students adjustmenting new sports has on school life adjustment has been verified. After doing so, the below results has been induced. First, physical self-efficacy had meaningful difference according to physical exercise experience. Second, physical education satisfaction had no meaningful difference according to physical exercise experience, but showed to have influential power. Third, School life adaptation had meaningful difference according to physical exercise experience. On the other hand, school surrounding adaptation had no meaningful difference according to physical exercise experience, thus it shows that it is not related. Fourth, physical self-efficacy showed to have difference according to recognized health status. Fifth, Physical self-efficacy of students participating in new sports education and general physical education did not have meaningful difference. Sixth, Physical education satisfaction of students participating in new sports education and general physical education did have partial differences. Seventh, School life adaptation of students participating in new sports education and general physical education did have partial affective power. Eighth, Physical self-efficacy did showed to have partial positive affect on the physical education satisfaction. Ninth, Physical education satisfaction did showed to have positive affect on school life adaptation. Lastly, in school regulation adaptation, when physical education guidance material satisfaction and physical education environment satisfaction has co-relationship, physical education guidance material satisfaction showed to have negative co-relationship, thus as physical education guidance material satisfaction increases the school regulation adaptation decreases. In addition, physical education environment adaptation has positive relationship, thus as physical education environment adaptation increases, school regulation adaptation increases. As shown, in school physical education non experienced new sports is having direct and indirect affect on student’s physical self-efficacy, physical education satisfaction, and school life adaptation. Moreover physical self-efficacy has partial affect on physical education, and physical education satisfaction has direct relationship has school life. Thus we found out that these three causes are co-related.

We extract hand region by using color information, because it is an important feature for human vision to distinguish objects. Because pixel values in images are changed according to the luminance and lighting source, it is difficult to extract hand region exactly without previous knowledge. We generate a hand skin model at leaning stage, and extract hand region from images by using the model. We also use Kalman filter to consider the change of pixel values in hand skin model. Kalman filter restricts the search area for extracting hand region at next frame also.
