This paper describes trajectory generation of a riobot arm by self-organizing neural networks. These neural networks are based on competitive learning without a teacher and this algorithm which is suitable for problems in which solutions as teaching signal cannot be defined-e.g. inverse dynamics analysis-is adopted to the trajectory generation problem of a robot arm. Utility of unsupervised learning algorithm is confirmed by applying the approximated solution of each joint calculated through learning to an actual robot arm in giving the experiment of tracking for reference trajectory.

The purpose of this study was to analyze the effective variables which influence family strengths. In particular, influencing variables were analyzed according to sex, generation, and family pattern. There were 703 participants aged over 20 years in Gwangju and Seoul. All participants completed a questionnaire and the data were analyzed using SPSS. The results were as follows: 1. The average scores of family strengths were higher than the median. Regarding subdimensions, 'value system sharing' had the lowest score. 2. Family strengths were related to its subdimension and some variables. 3. Family strengths were influenced by living condition, self-esteem, depression, the cognition of family function, and family value orientations. However, the influencing variables were different according to sex, generation, and family patterns. In conclusion, in order to improve family strengths, it is necessary to develop 'value system sharing', enhance self-esteem, and reduce depression. Further, when we deal with family strengths, it is necessary to vary methodology.

In this study, we investigate the multi-carrier spread spectrum (MCSS) communication system which adopts the self-encoded spread spectrum in a downlink synchronous channel. It is very difficult to completely eliminate the frequency offset in practical channel scenarios. We demonstrate that the self-encoded MCSS (SE-MCSS) with iterative despreading manifests a remarkable immunity to residual frequency offset. The SE-MCSS can be an excellent candidate for the future generation of wireless services.

Background and objectives: One-person households are the fastest growing family type in Korea. They bring social concerns such as weakened social integration, increasing poverty and social isolation. They are not homogeneous but heterogeneous groups depending on their socio-demographic characteristics including generation. This study compared the life satisfaction level as well as factors affecting it among the three one-person household generations Methods: The 13th wave of the Korea Welfare Panel dataset with 1,187 respondents was utilized. For data analysis Chi-square test, analysis of variance and hierarchical regression analysis were employed. Generations are divided into three, namely young adult (20-39), the middle-aged (40-64) and the elderly (65 and over). Result: The life satisfaction level was highest among the young adult one-person household generation, followed by the middle-aged and the elderly generation. The common factors affecting life satisfaction of the three generations were physical as well as mental health, including self-esteem and depression. However, there were more factors different from generation to generation. As for the young adult, age, religion, and smoking were significant. As for the middle aged and the elderly, gender (male) and income were significant. Additionally, age, home-ownership and drinking were significant to the elderly generation. Conclusions: As there are differences as well as similarities among the three generations, policies for one-person households need to be devised considering these findings. For all generations, both physical and mental health policies are needed. For young adult strengthening social relations, providing decent jobs, and promoting anti-smoking policy are major agenda, and for the middle-aged and the elderly, assisting in social capital accumulation (for male), providing stable jobs and diverse leisure activities, and securing income. Additionally, for the elderly, expanding the social security system and housing support are needed.

This study explored the relationship between Generation MZ female consumers' participation in sports activity, consumption of body-exposing sportswear, body-esteem, and appearance management behavior. In-depth interviews were conducted with twenty Generation MZ female consumers who regularly participate in sports activity and consume body-exposing sportswear. Based on transcriptions of in-depth interviews conducted with research subjects, the researcher and two assistant researchers collectively categorized and compared common characteristics found in their responses, categorized according to themes using units of words/terms and paragraphs. The main finding were as follows. Firstly, Generation MZ female consumers participated in various sports activities for an average of approximately one hour, three times per week. The effects of such participation were improvements in physical and psychological health. Secondly, Generation MZ female consumers considered aesthetical, functional, and economical factors when they consumed body-exposing sportswear, regardless of the activity in which they participated. This sportswear served to increase the efficiency of exercise and also played a motivational role. Thirdly, the overall body-esteem of Generation MZ female consumers who participated in sports activity regularly and consumed body-exposing sportswear was high. Fourthly, Generation MZ female consumers who regularly participated in sports activity and consumed body-exposing sportswear were practicing active appearance management behavior in order to show how their body had been shaped by sports activity. In addition, they were pursuing four self-images: "polished image pursue", "self-care image pursue", "natural image pursue", and "trustworthy image pursue".

The purpose of this study was to analyze the social perceptions toward the society from the new generation undergraduate students. The questionnaire consisted of the general backgrounds to respondents, the satisfaction on their living domain, the characteristics of new generation students, the attitude for the life and the occupation, the perspectives of life achievement, the viewpoint of the society, and the attitude toward the religion, the selected self, and 7 items for the social common opinion. The validity and the reliability of questionnaire were accepted to considerable extent through pre-test. The data obtained from the students of the selected universities were analyzed by SPSSWIN 6.0, and the statistical techniques used for this study were ANOVA, $Crosstabs(x^2\;test)$, t-test, frequencies, and percentage. The results were as follows : 1) The new generation undergraduate students had the higher satisfaction on the family and the relationship of friends than on the campus life, the self, and the society. 2) There was some negative image on the old generations and the new generations by the respondents. 3) Their objectives of the life were not obtaining the reputation and the higher positions but get the economic wealth for enjoying their life.

Purpose: This study examined factors influencing subjective quality of life in baby boom generation men. Methods: This was a descriptive survey study. Data were collected from 279 baby boom generation men from September to October 2012. The instruments used included a subjective quality of lifescale, a self-esteem scale, a spiritual well-being scale, a communication with spouse scale, a social support scale, and a job satisfaction scale. Data were analyzed using descriptive statistics, t-test, one-way ANOVA and Scheff$\acute{e}$ test, Pearson's correlation coefficients, and Hierarchical multiple regression. Results: All variables were positively correlated with subjective quality of life. As a result, factors influencing subjective life of quality were self-esteem (${\beta}$=.21, p<.000), social support (${\beta}$=.20, p<.002), job satisfaction (${\beta}$=.19, p<.001), communication with spouse (${\beta}$=.15, p<.004), spiritual well-being( ${\beta}$=.16, p<.004), and family income (${\beta}$=.15. p<.023). These factors accounted for 61% of the total variances. Conclusion: The findings indicate a need to develop nursing intervention programs for community health nurses in consideration of these variables to improve the subjective quality of life for baby boom generation men.

We investigate the effect of rise time of a pulse bias voltage on atmospheric plasma generation. With the faster rise time of the pulse bias, the glow discharge appears to be more uniformly generated along the electrodes. I-V measurement confirms that higher loading power can be obtained using the faster rise time. A new understanding for atmospheric plasma generation at a micro-gap electrode is suggested.

워라밸(Work Life Balance)을 중시하는 MZ세대가 조직 구성원이 되면서 목표 달성과 회사 이익 중심의 리더 지향 리더십은 중장기적으로 조직에서 좋은 성과를 내기 힘들어졌다. 회사는 조직 구성원들이 스스로 움직이는 셀프리더십과 구성원들의 직무만족과 조직몰입을 제고할 수 있는 리더십을 강화해야 한다. 하지만 선행연구에서는 팀장, 팀원, 경영자의 리더십을 한꺼번에 연구한 논문이 많지 않았다. 이에 본 연구는 팀장의 서번트리더십이 팀원의 셀프리더십과 조직효과성에 미치는 영향을 분석하였다. 또한 경영자의 감성리더십이 팀장의 서번트리더십과 상호작용을 하여 팀원의 셀프리더십에 조절효과가 있는지를 연구하였다. 또한 MZ세대와 비 MZ세대간의 경로계수에 대한 차이를 검증하였다. 이를 위해 PLS(Partial Least Square) 구조방정식을 이용하여 연구모형을 통계적으로 검증하였다. 온라인으로 직장인 중 357명의 팀원을 대상으로 설문을 수집하였다. 분석 결과 팀장의 서번트리더십은 조직효과성과 팀원의 셀프리더십에 유의한 영향을 미쳤으며, 팀원의 셀프리더십은 조직효과성에 유의한 영향을 끼쳤고 팀장의 서번트리더십과 조직효과성 간에 유의한 매개효과를 나타냈다. 또한 팀장의 서번트리더십과 팀원의 셀프리더십 간의 관계에서 경영자의 감성리더십이 정(+)의 조절 효과가 있었다. MZ세대는 팀장의 서번트리더십이 팀원의 셀프리더십에 긍정적 영향을 주는 경로와 팀원의 셀프리더십이 팀장의 서번트리더십과 조직효과성 사이에서 매개효과가 있는 경로에서 비 MZ세대와 차이가 있었다. 이러한 연구의 결과는 회사 내 경영자, 팀장, 팀원이 각자의 위치에서 조직효과성을 높이는 리더십을 개발할 수 있도록 다양한 이론적, 실무적 시사점을 제시할 것이다.
