The purpose of this study was to investigate the influences of children's perception of maternal acceptance-rejection and self-evaluation on learned helplessness. The Subjects were 371 fifth and sixth grade children. The helplessness scale, PAQ, PARQ were used. The data was analyzed by factor analysis, MANOVA, ANOVA and path analysis which was made through multiple regression analysis. The results were as follows: 1. The children's perceived maternal acceptance was significantly different depending on their parent's education level. In children's perceived parental rejection, there were gender differences. 2. In the children's self-evaluation, there were an interaction effect determined by the child's sex and the mother's education level, and a main effect of mother's education level. 3. Children's learned helplessness was significantly different depending on their mother's education level. 4. Children's perceived maternal acceptance(β=-0.36, p<.01) and rejection (β=0.17, p<.01) had a direct impact on their self-evaluation. Their self-evaluation(β=0.54, p<.01) and perceived maternal rejection(β=0.16, p<.01) had a direct impact on learned helplessness, but perceived maternal acceptance didn't have a direct impact on learned helplessness.

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.

This study analyzes child variables (child's temperament and child's depression) and parent variables (spouse support, social support, and job satisfaction) associated with married nurse parenting stress and provides data that can assist institutional support mechanisms. The research targeted 232 nurses at five general hospitals in Seoul, Gyeonggi-do, Jeolla-do, Chungcheong-do with elementary children. Data were analyzed using t-test, Pearson correlation analysis, and hierarchical regression analysis. The results of the study were as follows. First, there were significant correlations in parenting age, child number and parenting stress for mothers. Second, married nurses with high sociality of temperament, low sensitivity of temperament, and high activity of temperament child as well as married nurses with spouse support, social support, job satisfaction saw a reduction in high levels of parenting stress. Third, the results of this study showed that child depression, sensitivity of temperament, spouse support, and job satisfaction were factors to understand married nurses parenting stress. Child depression was an important factor to understand married nurses parenting stress. The results indicated variables affecting parenting stress of married nurses and suggested directions for the social welfare system.

Objective : In the cerebral aneurysm surgery, the goal is complete circulatory exclusion of the aneurysm without compromise of normal vessels. In an operating room, an operator should confirm the completeness and precision of the surgical result, before closing the wound. Object of this study was to determine which cases require intraoperative angiography. Methods : We reported our experience with 48 intraoperative angiographic studies performed during the surgical treatment of cerebral aneurysm of these 48 cases. There were 5 giant(10.4%), 15 globular(1.5-2.5cm)(31.25%) and 28 saccular(58.3%) aneurysm. We recorded the incidence of unexpected findings, such as residual aneurysms, major vessel occlusions. Using Fischer's exact test, we assessed whether unexpected angiographic findings showed any correlation with aneurysm site, size and clinical findings. Results : In 5 cases(10.4%), we detected unexpected angiographic findings which resulted in clip adjustment. By means of clip adjustment, an operator could restore the flow of two major arterial occlusion(4.2%) and also obliterate three persistent filling aneurysms(6.3%). Globular aneurysm was the only factor to predict unexpected angiographic findings(p<0.05). The subgroup of globular and giant aneurysm has a high risk of occlusion of the parent artery and its branches and/or residual aneurysm. There were two minor complications related to this procedure. Conclusion : Intraoperative assessment makes it possible to recognize and correct the technical defect. Particularly in globular aneurysm, we were able to prevent both the chance for another operation and the risk of postoperative complications.

Objectives: This study was designed to construct and test the structural equation model for the alcohol-related problem of alcohol use disorders. Methods: Data were collected by structured self-questionnaires from 229 male subjects who received > 8 (greater than 8) score on Alcohol Use Disorder Identification Test (AUDIT). The Data were analyzed by SPSS 21.0 and AMOS 21.0. Results: The model fit indices for the modified hypothetical model showed Q = 2.50, GFI = 0.90, and CFI = 0.94. As a result, Life position, parent's drinking problem, and alcohol expectancy had significantly direct effect on alcohol-related problem. Alcohol expectancy also had mediator effect between life position and alcohol-related problem. Conclusions: Consequently, the more positive life position, the less alcohol-related problem occurred. It is necessary to change their life position, which is individual factor, to prevent or reduce the alcohol related problem of alcohol use disorders.

Under the influence of nuclear radiation, the reliability of steam generators (SGs) is an important factor in the efficiency and safety of nuclear power plant (NPP) reactors. Motion planning that remotely manipulates an SG mobile tube-inspection robot to inspect SG heat transfer tubes is the mainstream trend of NPP robot development. To achieve motion planning, conditional traversal is usually used for base position optimization, and then the A^* algorithm is used for path planning. However, the proposed approach requires considerable processing time and has a single expansion during path planning and plan paths with many turns, which decreases the working speed of the robot. Therefore, to reduce the calculation time and improve the efficiency of motion planning, modifications such as the matrix method, improved parent node, turning cost, and improved expanded node were proposed in this study. We also present a comprehensive evaluation index to evaluate the performance of the improved algorithm. We validated the efficiency of the proposed method by planning on a tube sheet with square-type tube arrays and experimenting with Model SG.

Grit or perseverance as a factor for student success and life has gained increasing attention. Statistical methods have been the norm in analyzing various aspects of grit, but they do not address the transient and dynamic behavior well. We, for the first time, developed two linear dynamical models that specifically address the feedback structure of a child's desire to achieve a high grade point average (GPA) and the necessary effort that will increase stress between parents and a child. We call the dynamical model as GSES (Goal, Status, Effort & Stress). The two dynamical models incorporate the positive (i.e., achieving a high GPA) and the negative sides (i.e., effort and elevated stress and thus unhappiness) for being gritty or perseverant. Different types of parenting style and a child's characteristics were simulated whether parents and a child are empathetic or stubborn to their expectations and stress (i.e., willing or unwilling to change). Simulations show that when both parents and a child are empathetic to each other's expectation and stress, the most stable situations with minimal stress and effort occur. When a stubborn parent's and a stubborn child were studied together, this resulted in the highest elevation of stress and effort. Stubborn parents and a complying or empathetic child resulted in considerably high stress to a child. Interference from parents may unexpectedly result in a situation in which a child's stress is seriously elevated. The GSES model shows the U-shaped happiness curve (i.e., reciprocal of stress) caused by the increasing and then decreasing goal

The objective of this study is to understand disordered parent-child relationships of Reactive Attachment Disorder(RAD) systematically through the mother’ internal working model of child. In this study, RAD mothers’internal representations of the child were compared with mothers’of control group and association between mothers’ representation classifications and children’ attachment classifications was examined. Also individual differences in mother-child interaction by mothers’representation classifications was observed. The subjects of this study were 40 2-5 year-old children and their mothers, 20 attachment disordered dyads and 20 normal dyads of control group. Mothers were interviewed using the Working Model of the Child(Zeanah, Benoit & Barton 1986) to classify internal representations of child. Children’ attachment patterns were assessed by the Strange Situation Procedure. For observation of motherchild interaction, Each dyad was seen in DPICS devised by Eyberg and Robinson(1983). The results of the study were as follows：1) Among RAD group, 55% of mothers were classified as disengaged and 45% classified as distorted, while all mothers of control group were classified as balanced. In rating scales, there were significant differences in all 3 representation classifications in Intensity of involvement and Coherence. In Intensity of involvement disengaged representations had the lowest score and distorted representations had the lowest score in Coherence. 2) Mothers’representation classifications were related to children’ attachment classifications. All mothers of control group whose children were classified as secure were classified as balanced. Among RAD’ mothers, by contrast, 82% of mothers classified as disengaged had children classified as anxious-avoidant, 56% of mothers classified as distorted had children classified as disorganized / disoriented and 33% of mothers classified as distorted had children classified as anxious-resistant. 3) There were individual differences in mother-child interactions by mothers’representation classifications. In the child-centered play, mothers classified as disengaged used discriptive statement, reflective statement and discriptive-reflective question less than balanced mothers. Mothers classified as distorted used direct command and indirect command more than balanced mothers. In the clean-up task, mothers classified as disengaged and distorted used direct command and indirect command more than balanced mothers. The results of this study suggest that parents’working model of the child is an important factor to understand parent-child attachment relationships and their interactions. The understanding of parents’ working model of the child is thought to enrich our understanding of disordered parent-child relationships and to provide useful informations for specific and successful treatments.
