Based on characteristics of victims, the parent education program focused on building a new concept of personal respect toward their children and on changing overprotective and coercive parenting styles into democratic parenting. The social skills training program focused on building self-acceptance, self-esteem and interpersonal capabilities in victimized children. Three groups, each composed of 6 victims and their mothers, were compared to examine the effectiveness of the programs. Children in experimental group I showed marked increase in self-esteem. They also reported that their mothers' overprotective parenting decreased after participation in the parent education program, indicating the effectiveness of the intervention program.

This paper presents the characteristics analysis of Interior Permanent Magnet Synchronous Motors(IPMSMs). The development of this program is based on Matlab. In oder to achieve the development of the program, basis algorithm for IPMSMs analysis took advantage of equivalent magnetic circuit analysis technique. The equivalent magnetic circuit analysis for IPMSMs are based on a rotate synchronous d-q reference frame. The mathematical model of the d-q frame voltage equations is used frequently for the analysis of IPMSMs. This program can consider a cross saturation effect and a iron loss and mechanical loss, and provide fast analysis results of IPMSMs characteristics.

Because linear motor directly drives linear motion, it does not need conversion equipment such as belt and gear. Especially linear pulse motor provide more precise positioning and large force of linear pulse motors. As current manufacture technic of linear pulse motor is much to be desired at home. This motor lay out to make use of computer aided design program, In this paper the experimental motor is 2-phases 4-poles hybrid pulse motor which has teeth per pole Simulation program is divided its function into 4 parts - air gap permeance analysis, permanent magnet & non-linear core operating point determine, winding configuration, leakage flux analysis. It is possible to make motor static and magnetic characteristics for this simulation program. Also, by varying input parameters of the program, experimental motor is to be compared to motor characteristics.

When an escalator is developed or modified for improved performance, estimation of dynamic characteristics of the escalator is required. But modeling of the escalator for a design purpose is very difficult and time consuming process. Especially, it is very difficult for the designer to use the simulation model during design process because it takes time and also the designer needs to know how to use the simulation program. In order to solve these problems, a graphic user interface program that can predict dynamic characteristics of an escalator is developed for the designer. Since this program has the necessary complicated escalator model inside, the designer does not have to know how to use the simulation program and design parameters can be obtained while design is in progress. The developed designer oriented interface program is explained and an example is shown.

Including 425 Program, which is Korean military surveillance and reconnaissance satellite, there were mostly civil-driven space programs in Korea. However, there are increasing numbers of military demand-driven space program in nowadays. Furthermore, it is positive effects on launch vehicle development in Korea that the termination of Korea-U.S. missile guideline. In this paper, it emphasizes the needs of system engineering(SE) management method which meets both defense system's characteristics and space's characteristics. These characteristics are such as non-fixable after the launch, the security issue in defense system. And it also introduces SE tool, methodology and its philosophy. There are several functions that data management, issue management, risk management, and technical requirement management. Also describing its implications and direction of improvement.

The present study employed a pretest-posttest quasi-experimental design model in order to evaluate the effectiveness of the Respected Parents & Respected Children (RPRC) parent education program for mothers of early school-age children. Ninety mothers were randomly assigned to an intervention (n=45) group or a control group (n=45). Mothers in the intervention group participated in 8 weekly sessions of the parent education program. After the termination of the program, the differences between pretest and posttest were analyzed in terms of both maternal parenting characteristics (i.e., parenting behavior, parenting efficacy, parenting stress, and co-parenting) and children's social competence. The results indicated that only in the intervention group, self-reported positive parenting characteristics were significantly improved and negative parenting characteristics were significantly decreased. There were no significant effects of the program on children's social competence as rated by the mothers. These findings suggest that the RPRC parent education program is effective in changing parenting characteristics known as crucial predictors of child outcomes.

자활사업은 국민기초생활보장제도가 도입된 이래로 우리나라 빈곤정책의 주요한 변화를 가져왔다. 자활사업 참여자의 특성은 성별, 연령, 학력과 같이 시간에 따라 크게 변하지 않는 속성을 지닌다. 자활성과와 관련한 수급자의 특성을 연구함으로써 주요 대상 집단을 설정하고 이에 따라 자활사업의 효과적인 제공도 가능하다. 이 연구는 GLM분석을 통해 자활사업 참여자의 특성이 자활성과에 미치는 영향을 주효과와 상호작용효과에 의해 분석하였다. 분석결과, 학력, 자활사업유형, 지역, 소득, 연령, 보호아동유무, 성별 변인이 정서적 자활성과와 경제적 자활성과에 대해 영향을 미친 것으로 드러났다. 자활사업 참여자의 특성에 따라 자활성과에서 차이가 있으므로 자활사업의 프로그램을 참여자의 특성에 맞게 세분화하여 제공할 필요가 있다.

Purpose: The purposes of this study were to assess the efficacy and usefulness of the career ladder program in a hospital and to evaluate nurses' satisfaction with the program. Methods: The study was conducted using a survey consisting of 14 questions on the appropriateness, necessity and usefulness of the career ladder program. The data were gathered from 403 nurses in a hospital. We assessed differences in responses according to the participants' workplace, age, educational background, marital status, experience (total years and years at current working place). We analyzed the data using SPSS/WIN 12.0. Results: Nurses acknowledged that the career ladder program is necessary and profitable within the nursing field, but they worried about the appropriateness of the nurse's role at each career level and rationality of the portfolio. The study also identified nurses' characteristics that were significant factors in explaining nurses' satisfaction with the career ladder program. Finally, we identified complaints and improvements for the program. Conclusion: We assessed differences in attitude towards the career ladder program according to nurses' characteristics.

Intumescent system is a highly effective flame retardant technology that takes advantage of the mechanism of foaming and carbonization. In order to materialize Intumescent system, it is necessary to use reinforcement material to improve the strength of the material. In this study, we used kenaf as a natural fiber to manufacture intumescent/EVA (ethylene vinyl acetate) composites to improve mechanical and flame retardant performance. Finally two materials with different particle shape are applied to one system. Therefore, the influence factors of the particles with different shapes on the composite material were analyzed based on the tensile test. For this purpose, we have used the tensile strength analysis model and confirmed that it can only act as a partial strength reinforcement due to weak binding force between the matrix and particles. In the combustion characteristics analysis using cone calorimeter and UL 94, the combustion characteristics were enhanced as the content of Intuemscent was increased. As the content of kenaf increased, combustion characteristics were strengthened and carbonization characteristics were weakened. Through the application of kenaf, it can be confirmed that elastic modulus improvement and combustion characteristics can be strengthened, which confirmed the possibility of development of environmentally friendly flame retardant materials.
