Active surface adjustment of cable net structures is becoming significant when large-size cable net structures are widely applied in various fields, especially in satellite antennas. A general-duty adjustment method based on active cables is proposed to achieve active surface adjustment or surface profile reconfiguration of cable net structures. Piezoelectric actuators and voice coil actuators are selected for constructing active cable structures and their simplified mechanical models are proposed. A bilevel optimization model of active surface adjustment is proposed based on the nonlinear static model established by the direct stiffness method. A pattern search algorithm combined with the trust region method is developed to solve this optimization problem. Numerical examples of a parabolic cable net reflector are analyzed and different distribution types of active cables are compared.

The purpose of this study was to investigate the gender difference in adolescent's problem behavior and depression, and to analyze the effects of marital conflict, parenting behavior, parent's monitoring on adolescents' problem behavior and depression. Data obtained from 453 students in middle school was used for final analysis. This study found that female adolescents showed higher level of depression than male adolescents. Male adolescents reported higher level of marital conflict than female adolescents. On the other hand, female adolescents showed more mother's monitoring than male adolescents. Path analysis revealed that parenting behavior and parent's monitoring were negatively influenced by marital conflict. Adolescents' depression was negatively influenced by parenting behavior, but problem behavior was not influenced by parenting behavior. Father's monitoring had an impact on problem behavior of male and female adolescents. Depression was influenced directly by marital conflict, but problem behaviors were not directly influenced by marital conflict.

Based upon the ABC-X model and family systems theory, this study examined (1) problem-solving and behavioral strategies utilized by children in divorced families, and (2) factors related to children's post-divorce adjustment. Date were collected from 158 elementary school aged children and adolescents of divorced families in an urban area (56 male and 102 female). Results of this study indicated that there were significant age differences in problem-solving and behavioral strategies utilized by difficult family situations. Factors that are useful in predicting adjustment of divorced children are the following variables: sex, visitation frequency of noncustodial parent, quality of custodial parent-child communication, and length of divorce. Implications for knowledge as well as recommendations for future research are discussed.

Recruited from Korean-Chinese elementary schools in Shenyang and Harbin, China, 100 children living apart from their parents and experiencing non-maternal care provided information about the separation (reason and duration of parent-child separation, present location of parents, etc.), their adjustment to separation, and their perception of attachment with their caregivers. Results showed that although the separated children adjusted positively to parent-child separation in general, over 55% of them reported loneliness. Attachment with caregiver was the most significant influential variable on children's behavior problems. Duration of separation from father was related to children's hostility/aggression and hyperactivity/attention deficit problem, while duration of separation from mother influenced children's anxiety.

The resulting rapid urbanization in Korea in several decades caused the problem of housing shortage and the various residential stressors. In spite of the seriousness of the problem. there have been very few studies that analyses systematically the effects of residential stressors on the housing adjustment attitudes and housing management behavior. The purpose of this study is to analyse such effects by identifying, on the basis of a comprehensive theoretical model. For this purpose, 822 housewives were sampled form the household in Seoul and Chonju-City. The main results obtained are as follows. 1) Higher tendency to housing adaptation tan housing adjustment attitudes. The lower level of stress is observed in housing adjustment than housing adaptation. 2) The higher level of housing management behavior is observed in the loser level of residential stress, the smaller level of living space, the higher level of family adaptation ability and social support.

For the questions asked for LMS-based online evaluation the professor directly set exam questions, or use the automatic question-taking method according to the level of difficulty using the question bank divided by category. Among them, it is important to manage the difficulty of questions in an objective and efficient way, above all, in the automatic question-taking method according to difficulty. Because the questions presented to the evaluators may be different. In this paper, we propose an difficulty re-adjustment algorithm that considers not only the correct rate of a problem but also the time taken to solve the problem. For this, a logistic regression classification algorithm was used of machine learning, and a reference threshold was set based on the predicted probability value of the learning model and used to readjust the difficulty of each item. As a result, it was confirmed that there were many changes in the difficulty of each item that depended only on the existing correct rate. Also, as a result of performing group evaluation using the adjustment difficulty problem, it was confirmed that the average score improved in most groups compared to the difficulty problem based on the percentage of correct answers.

The purpose of this study was to investigate the relationship between the adjustment to life(school life, personal relations, home life, economic problem and time management), the clothing attitudes(status symbolism, fashionability, aesthetics, modesty, conformity, comfort aspect) and the clothing satisfaction. The questionnaires were administered to 456 university students in Chongju city to measure the demographic information, the adjustment to life and the clothing attitudes. As statistical analysis, frequencies, t-test, ANOVA, and correlation were used. The results were as follows: 1. The university students showed average state on the adjustment to their life. The adjustment to their home life and family was showed higher than other aspects, otherwise that to school life was showed lower than the others. 2. There were partially significant differences according to demographic variables of students on each aspect of the adjustment to life. 3. The university students showed moderate interest toward clothing attitudes. In the clothing attitudes, the interest toward comfort aspect was showed higher than other aspects, otherwise that toward conformity aspect was showed lower than the others. 4. There were partially significant differences according to demographic variables of students on each variable of the clothing attitudes. 5. There were partially significant correlations between each aspect of the adjustment and the clothing attitudes aspects.

In the network function virtualization environment, dynamic changes in network traffic will lead to the dynamic changes of service function chain resource demand, which entails timely dynamic adjustment of service function chain resource configuration. At present, most researches solve this problem through virtual network function migration and link rerouting, and there exist some problems such as long service interruption time, excessive network operation cost and high penalty. This paper proposes a dynamic adjustment method of service function chain resource configuration for the dynamic changes of network traffic. First, a dynamic adjustment request of service function chain is generated according to the prediction of network traffic. Second, a dynamic adjustment strategy of service function chain resource configuration is determined according to substrate network resources. Finally, the resource configuration of a service function chain is pre-adjusted according to the dynamic adjustment strategy. Virtual network functions combination and virtual machine reusing are fully considered in this process. The experimental results show that this method can reduce the influence of service function chain resource configuration dynamic adjustment on quality of service, reduce network operation cost and improve the revenue of service providers.

This longitudinal study investigated developmental changes in temperament and examined social adjustment problems by early temperamental characteristics and developmental patterns of temperamental change during infancy. Subjects were 153 six-month-old infants and their mothers. Infant temperament and toddler's problem behavior were measured by the Infant Behavior Questionnaire-Revised (Garstein & Rothbart, 2003) and the Toddler Behavior Checklist (Larzelere et al., 1989), respectively. Results showed that distress to limitations, high pleasure, perceptual sensitivity, and approach increased with age, while activity level, cuddliness, and vocal reactivity decreased. Infants with high scores in activity level, fear, sadness, and approach at 6 months showed more problem behaviors at 18 months. Infants showing abrupt developmental change of high pleasure and perceptual sensitivity developed more negative behavior.
