The purpose of the present study was to verify the structural relationship among task commitment, self regulation learning ability, parent support, satisfaction and achievement in gifted education. In this study, factors affecting the performance of gifted education are based on Differentiated Model of Gifted and Talent($Gagn{\acute{e}}$, 2004). Participants attended a 182 student in institutes for the gifted education in the city office of education in Korea. A hypothetical model was proposed, which was composed of task commitment, self regulation learning ability and parent support as exogenous variables; and satisfaction and achievement as endogenous variables. The results of this study are as follows: First, task commitment, self regulation learning ability and parent support had significant effects on gifted education's satisfaction. Second, task commitment and parent support had significant effects on gifted education's achievement.

This study examined the effects of maternal parenting behaviors, children's social information processing, daily hassles, and emotional regulation on school-age children's aggressive behaviors using Structural Equation Modeling(SEM) analysis. Subjects were 589 children in 4, 5, 6th grade and their mothers from three elementary schools in Seoul, Korea. Data were analyzed with descriptive statistics and SEM analysis by SPSS 12.0 and AMOS 4.0. The SEM shows differences between overtly aggressive and relationally aggressive children. Maternal parenting behaviors affected their children's overt aggression through children's emotional regulation. Additionally, maternal parenting behaviors affected children's overt aggression through children's daily hassles and social information processing. Maternal parenting behaviors influenced children's relational aggression through children's daily hassles and children's social information processing.

This study created a structural model of the influence of paternal and maternal meta-emotion philosophy and children's emotion regulation in terms of their social competence and confirmed the nature of the relationship among the variables. For the purpose of this study, data was collected, targeting 363 children in the $5^{th}$ and $6^{th}$ elementary school grades from schools located in Seoul. The main results of this study were as follows: First, both paternal and maternal meta-emotion philosophy had an influence on children's emotion regulation and emotion dysregulation. Next, paternal and maternal meta-emotion philosophy did not appear to have a significant influence on children's social competence in a direct manner. The complete mediation effect of emotion regulation in regards to the influence of paternal and maternal meta-emotion philosophy upon children's social competence was confirmed. It was also found that parental meta-emotion philosophy had an influence upon children's social competence in an indirect manner through children's emotion regulation in the period of middle childhood.

Overload vehicles have demoralizing influence upon the social overhead capital, economics of nation, traffic flow and road safe as various components. Accordingly, this study established a ubiquitous sensor network system to develop an intelligent regulation system to monitor overloaded vehicles in motion. and Unlike WIM, after detecting the axle of driving vehicles by measuring deformation of roads, this system calculates the weights of vehicles by using signals from the strain sensors installed under the road and an analysis method. Also the study conducted an simulation test for vehicle load analysis using genetic algorithm. and tested wireless sensor for USN system.

Structural acceleration regulation is a means of managing structural response energy and enhancing the performance of civil structures undergoing large seismic events. A quadratic output regulator that minimizes a measure including the total structural acceleration energy is developed and tested on a realistic non-linear, semi-active structural control case study. Suites of large scaled earthquakes are used to statistically quantify the impact of this type of control in terms of changes in the statistical distribution of controlled structural response. This approach includes the impulses due to control inputs and is shown to be more effective than a typical displacement focused control approach, by providing equivalent or better performance in terms of displacement and hysteretic energy reductions, while also significantly reducing peak story accelerations and the associated damage and occupant injury. For earthquake engineers faced with the dilemma of balancing displacement and acceleration demands this control approach can significantly reduce that concern, reducing structural damage and improving occupant safety.

Structural qualification plan (SQP) for aerospace vehicle is based on material certification methodology, which must be approved by certification authority. It is internationally required to use of statistically based material allowables to design aerospace vehicles with aerospace materials. In order to comply with this regulation, it is necessary to establish relatively large amount of database, which increases test costs and time. Recently NASA/FAA develop the new methodology which results in cost, time, and risk reduction, and satisfies the regulation at the same time. This paper summarizes the certification methodology of materials system as a part of structural qualification plan (SQP) of aerospace vehicles and also thermal management of the vehicle system, like thermal protection materials system and thermally conductive material system. Materials design allowable was determined using this method for a carbon/epoxy composite material.

Recently, US NRC revised fracture toughness requirements as 10CFR50.61a to reduce the conservatism of 10CFR50.61. However, unlike previous studies relating to the initial regulation, structural integrity evaluations based on the alternative regulation are not sufficient. In the present study, PTS and P-T limit curve evaluations were carried out by using both regulations and resulting data were compared. With regard to the PTS evaluation, the results obtained from the alternative requirements were satisfied with the criterion whereas those obtained from the initial requirements did not meet the criterion. Also, with regard to the P-T limit curve evaluation, operating margin by 10CFR50.61a was greater than that by 10CFR50.61.

Neuromedin U receptor 1 is a GPCR protein which binds with the neuropeptide, neuromedin. It is involved in the regulation of feeding and energy homeostasis and related with immune mediated inflammatory diseases like asthma. It plays an important role in maintaining the biological clock and in the regulation of smooth muscle contraction in the gastrointestinal and genitourinary tract. Analysing the structural features of the receptor is crucial in studying the pathophysiology of the diseases related to the receptor important. As the three dimensional structure of the protein is not available, in this study, we have performed the homology modelling of the receptor using 5 different templates. The models were subjected to model validation and two models were selected as optimal. These models could be helpful in analysing the structural features of neuromedin U receptor 1 and their role in disorders related to them.

The main aim of the current study is to examine the effects of mothers' parental beliefs and mother-child attachment on school-aged children's time management and life management skills through the mediation effects of children's self-regulation. Study participants included a total of 317 fifth- and sixth-grade children at elementary schools located in Seoul and Gyeong-gi area, and their 317 mothers. Children and mothers completed questionnaires and Structural Equation Modeling was adapted as the main analysis technique. The findings were the following: First, mothers' parental beliefs that emphasize the child's independence were significantly related to greater self-regulation ability in children, indicated by cognitive, motivational, and behavior regulation. Second, better quality of mother-child attachment perceived by children was also found to predict greater self-regulation in children. Third, children's self-regulation was strongly related to time and life management skills. When the child is better at self control, the child showed greater management skills, both in time and everyday life. Finally, as hypnotized, the test yielded a significant mediation effect of self-regulation in the association from mothers' parental beliefs and mother-child attachment to children's time and life management skills. The findings suggested the important role of parental beliefs about child rearing and attachment between mother and child in developing self-regulation and management skills of school-aged children.
