  • The process of political and economic transformation of Germany following reunification has been well documented, but the question of psychological reunification is addressed by the present study. In order to analyze how East German adolescents adapted to the changing socialization context following reunification, questionnaires on values orientation, self-efficacy, subjective well being, coping, attitude toward violence and toward reunified German society were administered to 149 high school students. Results indicated that subjects had high scores on value orientation in private life and used active coping strategies. They had high scores in self-efficacy and subjective well being. Their political attitudes were complex and diverse. There were group differences by gender and type of school attended.

  • Globalization, unpredictable markets, increased products customization and frequent changes in products, production technologies and machining systems have become a complexity in today's manufacturing environment. One key strategy for coping with the evolution of this situation is to develop or apply an enable technology such as intelligent manufacturing. Intelligent manufacturing system (IMS) is characterized by decentralized, distributed, networked compositions of heterogeneous and autonomous systems. The model of IMS is inherited from the organization of the living systems in biology and nature so that the manufacturing system has the advanced characteristics inspired from biology such as self-adaptation, self-diagnosis, and selfhealing. To prove this concept, an innovative system with applying the advanced information and communication technology such as internet of things, cognitive agent are proposed to integrate, organize and allocate the machining resources. Innovative system is essential for modern machining system to flexibly and quickly adapt to new challenges of manufacturing environment.

  • In this paper, we propose a method of cooperative control(T-cell modeling) and selection of group behavior strategy(B-cell modeling) based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-call respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based of clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.

  • By introducing the notion of constraint-oriented fuzzy inference, we will show that it provides us ways of fuzzy control methods that has abilities of adaptation, learning and self-organization. The basic supporting techniques behind these abilities are“hard”processing by Artificial Intelligence or traditional computational framework and“soft”processing by Neural Network or Genetic Algorithm techniques. The reason that these techniques can be incorporated to fuzzy control systems is that the notion of“constraint”itself has two fundamental properties, that is, the“modularity”property due to its declarativeness and the“logicality”property due to its two-valuedness. From the former property, the modularity property, decomposing and integrating constraints can be done easily and efficiently, which enables us to carry out the above“soft”processing. From the latter property, the logicality property, Qualitative Reasoning and Instance Generalization by Symbolic Reasoning an be carried out, thus enabling the“hard”processing.

  • This paper describes a neural network based fuzzy PID control scheme. The PID controller is being widely used in industrial applications. However, it is difficult to determine the appropriated PID gains in nonlinear systems and systems with long time delay and so on. In this paper, we re-analyzed the fuzzy controller as conventional PID controller structure, and proposed a neural network based self tuning fuzzy PID controller of which output gains were adjusted automatically. The tuning parameters of the proposed controller were determined on the basis of the conventional PID controller parameters tuning methods. Then they were adjusted by using proposed neural network learning algorithm. Proposed controller was simple in structure and computational burden was small so that on-line adaptation was easy to apply to. The experiment on the magnetic levitation system, which is known to be heavily nonlinear, showed the proposed controller's excellent performance.

  • In this paper, a fuzzy sliding mode control that combines with a adaptive self-regulating technique is proposed for manipulators with uncertainties. Especially the system uncertainties is approximated using fuzzy rule adaptation technique. The proposed controller is composed of the equivalent control that includes the approximation of the system uncertainties and the hitting control that is used to constrain the states of the system to maintain on the sliding surfaces and used to guarantee the system robustness. Simulation results are presented to show the effectiveness of the proposed controller

  • 본 연구의 첫 번째 목적은 불완전고용에 영향을 미치는 선행요인에 대해 살펴보는 것이고, 두 번째 목적은 불완전고용이 조직 적응에 미치는 영향을 살펴보는 것이다. 연구는 종단으로 설계되어 2회의 설문조사를 통해 자료가 수집되었으며, 1차 조사 시점에서 미취업 상태에 있었으나 2차 조사 시점에서는 재취업한 153명으로부터 자료를 얻었다. 불완전고용의 측정치는 임금, 사회적 지위, 기술활용도 및 고용형태변화의 차원에서 여섯 개의 측정치-'임금변화비(현재 임금/실직 전 임금)', '지위변화비(현재 직업지위/실직 전 직업지위)', '학력격차비(요구학력/실제학력)', '정규직에서 비정규직으로 고용형태가 변화했는지의 여부' 및 자기보고방식의 지각된 과잉자격 척도의 '성장가능성부재'와 '자격불일치' 요인-로 측정되었다. 먼저 불완전고용에 영향을 미치는 선행요인의 효과를 살펴보고자, 선행요인으로 인구통계변인(성별, 연령, 학력 및 실업기간), 상황변인(경제적 곤란도와 부양가족 수), 개인특성변인(구직효능감, 우울·불안, 잠재적 기능)을 설정하였다. 주요 결과로는 연령이 높을수록 임금과 지위는 하향 변화하였고, 경제적 곤란도가 높을수록 자신의 학력보다 낮은 학력이 요구되는 직업에 재취업하였으며, 부양가족 수가 많을수록 직업지위가 하향 변화하였다. 개인특성변인 중 실업기간 동안 취업의 잠재적 기능을 유지할수록, 성장가능성부재로 측정된 불완전고용의 가능성을 낮추었고, 구직효능감이 높은 경우에도 마찬가지 결과를 보였다. 실업기간 동안 우울·불안 수준이 높을수록 자신의 학력보다 낮은 학력이 요구되는 직업에 재취업할 가능성이 높아지는 것으로 나타났다. 다음으로 불완전고용이 직무-조직 적합도 지각, 조직몰입, 직무만족 및 이직의도로 측정된 조직 적응에 미치는 영향을 살펴본 결과 학력격차비 측면에서 불완전고용의 정도가 높을수록 개인-조직 적합도, 정서몰입 및 직무만족을 낮게 지각하였다. 또한 정규직에서 비정규직으로 변화할수록 정서몰입과 직무만족을 낮게 지각하였다. 그리고 성장가능성부재와 자격불일치는 조직 적응 전반에 걸쳐 유의한 영향을 미치는 것으로 나타났다.

  • This study was focused on the relationships between menstrual history and psychological variables in middle school girls. The study included 165 students. Self image, optimism and self-efficacy are measured structured questionnaires each. Statistical analysis was performed using t-test, ANOVA and Scheffe's test. The proportion of the students with bleeding period less than 7 days was higher in the group with high self image(p=.002). The self image was higher in the group who take analgesics occasionally than the group who take daily(p=.009) and in the group with irregular menstruation(p=.024). Emotional tone was higher in the group with irregular menstruation(p=.008), and psychopathology was higher in the group who take analgesics occasionally(p=.008). Family relationship was higher in the group with bleeding period less than 7 days(p=.004), in the group who take analgesics occasionally(p=.007) and in the group with irregular menstruation(p=.015). Mastery and coping was higher in the group with bleeding period less than 7 days(p=.026). Adaptation was higher in the group with irregular menstruation(p=.034). Also optimism was higher in the group with bleeding period less than 7 days(p=.005), in the group who experienced menorrhalgia a few years after menarche(p=.014) and the group with irregular menstruation(p=.027). Self-efficacy was higher in the group of polymenorrhea(p=.029). Because menstruation is related with psychiatric factors, it is necessary to ask menstruation history and psychiatric status. This study can be used in the development of the questionnaire for the oriental medical examination.

  • The purpose of this study was to examine the effects of MMTIC group counseling program on self-esteem of elementary school students. The hypothesis was that the self-esteem test scores of experimental group would be significantly higher than those of control group. The subjects were the twenty 5th graders sampled from the 66 5th graders of D Elementary School in Boryeong City based on self-esteem test scores. The 10 subjects were randomly assigned experiment group and others were assigned control group. The self-esteem test by Mun, Yong Woo (2002) modified from the measurement of Kim, Heui Hwa (1989) was administrated as pre and post test. The experimental group has experienced MMTIC group counseling program. On the other hand, the control group has not been given any advice during the counseling periods. The counseling was once a week at two o'clock in the afternoon for ten weeks from the eleventh of May to sixteenth of July in 2003. Each counseling session lasted sixty to eighty minutes. The group counseling program, which has been used in this research, has been adapted to the level of elementary students with the consideration of MBTI and MMTIC Workshop in reference to a few theses related to MMTIC development program (Jung, Gyeong Yeon, 2001: Gang, Jae Jeong, 2002; Lee, Jae Mo 2002). The results were analysed by t-test. These statistics with a quantitative result has been supplemented with a qualitative analysis by a questionnaire and the descriptions of impression of subjects of experimental group. The results of this research was that the analyses of the questionnaire and a description of their impression have shown that the counseling has had an significantly impact on their understanding themselves and others. In particular, this program has been positively conducive to receptive relationships to others. In conclusion, the MMTIC group counseling program has helped elementary students I understand themselves and others, increase receptive competence, encourage their confidence, improve personal relationships and enhance their adaptation to their school life. It suggests that this program has a feasible effect on children's sense of self-esteem.
