This study describes optimization methods for adjustment of helicopter main rotor tracking and balancing (RTB). RTB is a essential process for helicopter operation and maintenance. Linear and non-linear models were developed with past RTB test results for estimation of RTB adjustment. Then global and sequential optimization methods were applied to the each of models. Utilization of the individual optimization method with each model is hard to fulfill the RTB requirements because of different characteristics of each blade. Therefore an ensemble model was used to integrate every estimated adjustment result, and an adaptive method was also applied to adjustment values of the linear model to update for next estimations. The goal of this developed RTB adjustment optimization program is to achieve the requirements within 2 run. Additional tests for comparison of weight factor of the ensemble model are however necessary.

This study examined the direct and indirect influences of parental behavioral control on adolescents' school related adjustment by exploring pathways between parental behavioral control, adolescents' anxiety, and school related adjustment. Participants were composed of 319 high school 1st graders (153 male and 165 female students) from the Seoul area. They completed questionnaires on parental behavioral control, adolescents' anxiety, and adolescents' school related adjustment. The collected data were analyzed using Pearson's correlation coefficients, Factor Analysis, and Structural Equation Modeling. It was adapted to SPSS version 19.0 and Amos version 21.0 for Windows. The results indicated that adolescents' anxiety partially mediated the association of parental behavioral control and adolescents' school related adjustment. More concretely, direct effect of adolescents' anxiety on adolescents' school related adjustment were slightly greater than the direct/indirect effects of parental behavioral control on adolescents' school related adjustment. The effect of adolescents' anxiety on adolescents' school related adjustment was the greatest among all associations between research variables. The findings of this study have implications for research and practice that highlights the important considerations for proper parental behavioral control and reducing adolescents' anxiety that should be emphasized to improve adolescents' school related adjustment. We believe that improved parental behavioral control needs to be emphasized when designing prevention and parent intervention education programs for adolescents' psychological problem and school related adjustment.

Purpose: This study intends to clarify the relative importance and character of the college student's attachment to their parents. We examined the effect that the father and mother attachments have en their self-efficacy and adjustment to their college life. Method: The subjects were 271 students who attendee a university. For this study, we used the inventory of the Parent Attachment-Revised version by Armsden and Greenberg, a self-efficacy test by Sherer et al. and the investigation far adjustment to college life by Barker & Siryk. The data were analyzed by t-test, ANOVA, Duncan test and simple multiple regression analysis on an SPSS WIN 10.0 program. Results: There was a significant differences in the attachment to the father according to their grades and in the attachment to the mother according to their type of residence. There was a significant difference in the adjustment to their college life according to their grades. Regression analysis on attachment and self-efficacy suggested that attachment has an influence on self-efficacy. Regression analysis on attachment and adjustment to college life suggested that attachment has influence on the adjustment to college life. Attachment also has an influence on academic adjustment, social adjustment, personal-emotional adjustment and institutional adjustment on the subscale of adjustment to college life. Regression analysis on self-efficacy and adjustment to college life suggested that self-efficacy has an influence on adjustment to college life. Further, self-efficacy has an influence on academic adjustment, social adjustment, personal-emotional adjustment and institutional adjustment on the subscale of adjustment to college life. Conclusion: This study shows that there are relationships among attachment, self-efficacy and adjustment to college life. Especially, self-efficacy is a very important factor influencing the adjustment to college life. So, a plan designed to increase students' self-efficacy should be created based on the results of this study.

This research is performed to estimate quality of trial pavement for construction and analyze effect of fatigue life by using the pay factor. Specially, asphalt content which is difficult to control the pavement quality, is selected by pay adjustment standard factors and pay factor is calculated by asphalt content. This research is also analyzed to present relation of fatigue life according to asphalt content, to evaluate quality of the road pavement by calculating pay factor of sampling trial field mixture 2 times. This research confirms that it is different quality of road pavement according to pay factor changes. To analyze the fatigue life of pavement by using asphalt mixture for trial field. As a result, it is conformed that high pay factor could be high fatigue life of trial field. This means that pay factor using probability theory reflects road pavement fatigue life. Also, this study is included that beam fatigue test manufacturing specimen such as mixing type of plant which purvey asphalt mixture to trial field, compared with fatigue life of trial field. As a result, the fatigue life of specimen that is manufactured by mix type is higher than trial field specimen. This means that performance of road pavement can be reduced by gradation or other effects. Therefore, to exactly evaluate the quality of road pavement, pay factor should be calculated appling various pay adjustment standard factors such as gradation, air-void in U.S. states which is adopted pay adjustment.

The purpose of this study is to define the paths through which academic burnout and self-efficacy of middle school students affect school adjustment, verify the path model of each factor, and examine the mediator effects of self-efficacy. In line with this objective, the study conducted a survey on 713 third year students of 3 different middle schools in city G. The first finding of this study confirmed that the path coefficient and suitablility index were significant, indicating that the path model was also significant. Second, academic burnout had direct negative effects on self-efficacy and school adjustment, while self-efficacy has positive effects on school adjustment. Third, self-efficacy was confirmed to have meaningful mediator effects on academic burnout and school adjustment. Based on these findings, academic burnout caused by excessive demand for academic success on korean students has negative effects on school adjustment, but if self-efficacy is well developed as an individual factor, school maladjustment can be reduced. Thus this study confirmed that psychological factors, such as self-efficacy, are necessary in school adjustment. Future studies were suggested on the basis of this study's findings.

The focus of this study was finding out the relations among resilience of children separated from parents, child rearing factors and socio-emotional adjustment in Korean and Yanbian Korean-Chinese regions. Subjects were elementary school $5{\sim}6$ graders separated from their parents(184 in Korea and 81 in Yanbian). Data analysis was by Pearson's r, F-test and t-test. Resilience of Korean-Chinese children was higher than that of Korean children. Caregivers' child rearing behavioral factor than other child rearing factors was significant for children's resilience, and especially for Korean children, caregivers' child rearing psychological factor -efficacy and stress variables- were meaningful. Socio-emotional adjustment was significantly different between resilience high and low groups in both regions. Implications are that regional differences, caregivers' psychological and behavioral child rearing factors should be considered in supporting the development of children's resilience and socio-emotional adjustment.

This study was designed to identify the relation between the perceived family support and social adjustment of discharged patients with chronic mental illnesses. The subjects for this study were 50 patients with chronic mental illnesses receiving out-patient treatment at one general hospital and one private hospital in Seoul. The data were collected during the period from April 25, 1991 to May 27, 1991. The perceived family support was measured by the Family Support Scale developed by Hyun Sook Kang. A questionnaire which was developed by Weissman was modified by the author of this study to measure the Social Adjustment. The data were analyzed by descriptive statistics and Pearson Correlation Coefficients, using the SPSS program. The results of this study can be summarized as following ; 1) For the perceived family support, the mean was 2.63 points and the source of family support was almost always the mother. 2) For the social adjustment level, the mean was 2.62 points, and the results showed the best social adjustment was in the area of parental role and family adjustment, and the poorer adjustment was in the area of work and leisure. 3) The relationship between the perceived family support and social adjustment revealed a significant correlation.(r＝.38, p＜.05) Therefore the hypothesis “the higher the level of perceived family support, the higher the social adjustment level” was accepted. In conclusion, the study revealed that family support is an important factor related to the social adjustment level in patients with chronic mental illnesses.
