Regarding to the Domestic housing politics to improve residing environment and effective use of country land, apartment buildings have been constructed since early of 1970s. Now apartment is taking over 50% out of entire housing in Korea. In the view point of PV application to the apartment, PV has amny advantages because of the wideness of out-walls and high floors building in APT. Therefore, if APT could use the electricity produced by BIPV, we can solve more easily environment and energy problems caused by housing. The research conclusion by analysing conditions and application method to introduce BIPV application to APT in near future is as below. -The out look of APT has been developed periodically and recently gable roof or canopy is popular which PV installation is more favorable. -For Balcony part with double skin facade sassy window, It has a preferable condition to install on the wall depending on the window direction. -In case of shorter distance between buildings due to high ratio of outside measurement, it is more desirable to install PV on the roof than on the wall of Apartment by considering low solar altitude. -Also depending on the direction of APT building, it is more effective and productive in electricity in the broad surface of side wall of APT. -In case of superhigh floor APT where facade system is mostly double skin facade of curtain wall system, PV module can replace the traditional curtain wall and will reduce architectural materials and obtain various out look design thereof.

This study was conducted to investigate the influence that it has on the application pre and post balance index using method with spiral and reaction point balance taping application against 20 stroke patients. The taping application pre and post static eye opening balance index was statistically no significant difference in the Mean X Speed, and the Extent in X Dirction but in the Mean Y Speed, the Velocity Moment, and Extent in Y Direction, there were statistically significant difference(p<0.05). The taping application pre and post static eye closing balance inde was statistically no significant difference in the Mean X Speed, in Y Direction, there were statistically significant difference(p<0.05). From above results, the method of the applied taping was the equilibrium stability performance of the Y-axis than the stability of the balance of the X-axis, therefore it is considered to study the taping application method in the balance of detail stroke patients.

Objective: The aim of this study is to suggest the standard of the direction sign on the pendant switch of overhead cranes which can reduce human errors in control. Background: A great number of crane accidents occur in industries. One of the major causes of the accidents is the mistake in the control of cranes by confusing the orientation of crane movements. Nevertheless, three different direction sign styles, 'East, West, South, North (EWSN)', 'Forward, Backward, Left, Right (FBLR)', and arrows for four directions are used without standardization. Method: An overhead crane simulator was installed for a laboratory experiment. It could move along six directions by the control of a pendant switch. 90 participants were evenly assigned to the three different conditions of direction sign styles. The participants were asked to control the pendant switch according to the continuously appearing 16 direction signs on a monitor ahead. The participants were allowed to refer an orientation sign board on the ceiling representing correct movement directions of the overhead crane simulator. Results: The direction sign style, 'EWSN', showed statistically significant better performance in task completion time and number of errors than the other sign styles. The direction sign style, 'EWSN', adopting the cardinal direction system, made the participants clear in direction controls after customizing to the crane movements. However, the direction sign styles, 'FBLR' and the arrows adopting the relative direction system made conflicts in direction controls due to the egocentric view of human. Conclusion: The direction sign style, 'EWSN', is the most appropriate for the standardization of the direction sign on the pendant switch of overhead cranes. Application: The results of this study can be applied to the standardization of direction sign in the legal notification on the safety certifications of crane manufacturing.

Pixel classification is one of basic image processing issues. The general characteristics of the pixels belonging to various classes are discussed and the radical principles of pixel classification are given. At the same time. a pixel classification scheme based on image direction measure is proposed. As a typical application instance of pixel classification, an adaptive multi-level median filter is presented. An image can be classified into two types of areas by using the direction information measure, that is. smooth area and edge area. Single direction multi-level median filter is used in smooth area. and multi-direction multi-level median filter is taken in the other type of area. What's more. an adaptive mechanism is proposed to adjust the type of the filters and the size of filter window. As a result. we get a better trade-off between preserving details and noise filtering.

With the development of multimedia and optical technologies, application systems with facial features hare been increased the interests of researchers, recently. The previous research efforts in face processing mainly use the frontal images in order to recognize human face visually and to extract the facial expression. However, applications, such as image database systems which support queries based on the facial direction and image arrangement systems which place facial images automatically on digital albums, deal with the directional characteristics of a face. In this paper, we propose a method to detect facial directions by using facial features. In the proposed method, the facial trapezoid is defined by detecting points for eyes and a lower lip. Then, the facial direction formula, which calculates the right and left facial direction, is defined by the statistical data about the ratio of the right and left area in facial trapezoids. The proposed method can give an accurate estimate of horizontal rotation of a face within an error tolerance of $\pm1.31$ degree and takes an average execution time of 3.16 sec.

스마트폰과 같은 무선랜이 내장된 포터블 디바이스의 보급으로 누구나 무선랜을 사용하고 있다. 하지만 이러한 무선랜서비스는 인터넷의 접속과 위치 측위에 한정되어 있어 양질의 무선랜 서비스를 제공하는데는 한계가 있다. 따라서 무선랜의 센서화를 통해 적외선 센서방식과 같은 다른 대체방식으로 무선랜의 기능을 응용하여 자동적으로 위치를 인식할 수 있는 대체 인식 센서로서의 응용 방안을 제안하고자 한다. 센서화에는 무선랜과 엑세스포인트간의 신호감도를 사용하며, 무선랜 안테나 무지향성 신호출력으로의 조작을 가하고 이를 인식센서로 가정하여 방향을 인식하는 본 논문에서 제안한 알고리즘을 통하여 포토 커플러 등의 직접적인 센서가 없이도 인식센서와 같은 기능을 무선랜과 엑세스 포인트 간의 연결감도를 활용하여 그 기능을 수행할 수 있었다.
