The purpose of this study is to examine how adolescent children's exposure experience of domestic violence influences their psycho-social maladjustment. The SPSS 10.0 for Windows was used to analyze data obtained through 589 adolescents who attend middle school in Gwangju area. Major findings are as follows: 1. Domestic violence exposure in adolescent children was considerably serious; 84.4% child abuse by parents, 66.0% witness of father-to-mother abuse. 2. Child abuse and wife abuse had close relation in occurrence and severity. 3. Internalizing problems, externalizing problems, and social competence of adolescents were different by the victim of child abuse, the witness of wife abuse, and the style of domestic violence exposure. 4. Domestic violence exposure had a positive impact on the adolescent children's psycho-social maladjustment.

There is something valuable in Korean traditional architecture that does not change even after more than a number of years. Each design element of traditional houses has its own role to embody natural, healthy, and environment-friendly architectural planning. With traditional already-built examples located in the northern area of Gyeongbuk province, this study attempts to untangle some of the daylighting control issues in opening design. By looking at more than just photometric materials, at some threshold level, the whole of daylighting control characteristics of their openings is being surveyed from the viewpoint of geometric relationship between their roof structures and windows. As a glazing material, in addition, Korean traditional window covering paper, Changhoji, is evaluated for its transmittal performance under artificial and real skies as well.

Linearly graded profiles on the field area oxide are frequently used in power integrated circuits to reduce the surface electric field when power devices are operated in forward or reverse blocking modes. It is shown here that tapered windows can be made using the difference of etch rates between the bottom and the top layer of TEOS film. Annealed TEOS films are etched at a lower rate than the TEOS film without annealing Process. The fast etching layer results in window walls having slopes in the range of 25$^{\circ}$∼ 80$^{\circ}$ with respect to the wafer surface. Taper etching technique by annealing the TEOS film applies to high voltage LDMOS, which is compatible with CMOS process, due to the minimum changes in both of design rules and thermal budget.

Bluetooth is the most promising network paradigm which ca open the new area in the information technology. Especially, bluetooth can link all the electrical products and PCs(Personal Computer) to cellular phone or PDA. In this paper, the data from ECU which are gathered by scanner are communicated between tow PCs using the bluethooth modules. The acquired data are ECU's self diagnosis signal and sensor output signal. Self diagnosis signals are very important to check the ECU's state and sensor output signals. Using these data, the possibility of wireless communication with ECU is developed and verified. Protocol stack of bluetooth is L2CAP through HCI and wireless communication software of ECU's signal is developed using VC++ in Windows 98 environment.

This paper presents an 125MHz, 128-phase phase-locked loop using interpolation technique for digital timing recovery. To reduce the power consumption and chip area, phase interpolation was performed over only selected windows, instead of overall period. Four clocks were used for phase interpolation to avoid the output jitter increase due to the interpolation clock (clock used for phase interpolation) switching. Also, the output clock was fed back to finite-state machine (FSM) where the multiplexer selection signals are generated to eliminate the possible output glitches. The PLL implemented in a $0.25\mu\textrm{m}$ CMOS process and dissipates 80mW at 2.5V supply and occupies $0.84\textrm{mm}^2.

In this paper we proposed multi-directional matching windows combined by multi-dimensional feature vector matching, which uses not only intensity values but also multiple feature values, such as variance, first and second derivative of pixels. Multi-dimensional feature vector matching has the advantage of compensating the drawbacks of area-based stereo matching using one feature value, such as intensity. We define matching cost of a pixel by the minimum value among eight multi-dimensional feature vector distances of the pixels expanded in eight directions having the interval of 45 degrees. As best stereo matches, we determine the two points with the minimum matching cost within the disparity range. In the experiment we used aerial imagery and IKONOS satellite imagery and obtained more accurate matching results than that of conventional matching method.

Salesperson Monitoring System (SMS) is geographic based information system that supports business auditing, sales area coordinating and customer management for each salesperson. Conventional SMSs focus mainly on the monitoring or logging functions, i.e., a salesperson locating or moving trail tracking. However, the schedules have been planned by human planner, and they have rarely been managed with a software system like SMS. In this paper, a mixed integer programming model for a salesperson routing schedule is provided. Then, 2-phase Genetic Algorithm (GA) is proposed to make salesperson routing schedule. Experimental results show a validity of the proposed method.

Purpose: The purpose of this study was to identify influential factors on compassion fatigue in hospital nurses. Methods: A cross-sectional descriptive design was conducted with a survey of 358 general hospital nurses in Busan Gyeongnam area. For data analysis, descriptive statistics, Pearson's correlation coefficients, and multiple regression were performed using SPSS/WIN 18.0 for Windows. Results: The mean score was 28.53 in compassion fatigue. As a result of multiple regression analysis, empathic ability, stress coping strategy, current workplace, and academic background were statistically significant predictors explained 26.0% of the variance of compassion fatigue. Conclusion: It was suggested to consider emphatic ability, stress coping strategy, workplace, and academic background when developing a program available for preventing and easing nurses' compassion fatigue.

Passive House represents energy-saving technologies. It aims to save energy and provide comfort to the dwellers. The design and construction began in Germany, where it is commonly observed. In South Korea, implementation of the Passive House concept is difficult because of high construction costs and technological problems. This study performed a POE analysis to analyze the extents of satisfaction and knowledge about Passive House among those who live in them in Germany. The results found high satisfaction with functional aspects, such as ventilation, windows, doors, and the thermal bridge. These research results will provide application criteria for Passive House construction in South Korea.

An electrochromic(EC) cell was constructed using $WO_3$ as a electrochromic material and NiO as a counter electrode, deposited onto ITO-coated glass by the implementation of electron beam evaporation. The electrolytic media were both lithium and proton conducting polymers such as poly-acrylonitrile(PAN)-$LiClO_4$, poly-ethylene oxide(PEO)-$LiClO_4$, poly-vinyl butyral(PVB)-LiCl and PVB-H$_3$$PO_4$. Potentiodynamic cycling of the cells using PAN-$LiClO_4$, or PVB-$H_3$$PO_4$ electrolyte yielded a transmission variation of more than 40% at the wavelength of 632.8 nm within less than 10 sec response time at room temperature. These results indicate that these electrolytes, transparent in gel type, are premising for the application in large area electrochromic windows.
