This study was conducted to investigate the thermoregulatory responses and wearing behavior of the cold-sensitive men when exposed to the mild cold of 14$^{\circ}C$. Two sessions of experiment were carried out and five healthy young men for the cold-sensitive group(CSG) and four healthy young for the cold-insensitive group(CIG) participated in the study as subjects CSG maintained rectal temperature lower than CIG due to their thicker clothing resulted in larger decrease of rectal temperature. CSG maintained skin temperatures higher than CIG. CSG felt cooler than CIG but wore thicker clothing for thermal comfort and this made keep their sensation warmer. These results were discussed in terms of autonomic and behavioral temperature regulation.

The response of the adolescents toward school uniform regulations according to personal character and clothing needs was studied. To carry out this experiment, questionnaires were administered to 514 students in middle and high schools in Seoul and Gyeonggi-do. The collected data were analyzed with Factor analysis(Varimax rotation), Cronbach's ${\alpha}$, Frequencies Statistics, t-test, ANOVA, and multiple regression analysis using the SPSS WIN 15.0. By surveying on actual condition of uniform regulation in school, it was found that the existing uniform regulation was unnecessarily strict and caused stress leading a negative educational effect. Based on the relationship among the degree of regulation, stress, and student attitude toward school uniform regulation, stress and negative attitude to uniform regulation increased as the degree of regulation increased, resulting in an decrease in observance behavior of students. Since the stress from the school uniform regulation can be reduced by establishing rational law, which induced voluntary conduct of student to obey, it is important for student to participate in establishment of adoptable and reasonable school uniform regulation law.

In the restructured electricity market, Performance-Based Regulation (PBR) regime has been introduced to the distribution network. To ensure the network stability, this regime is used along with quality regulations. Quality regulation impose new financial risks on distribution system operators (DSOs). The poor quality of the network will result in reduced revenues for DSOs. The mentioned financial risks depend on the quality indices of the system. Based on annual variation of these indices, the cost of quality regulation will also vary. In this paper with regard to reclosing fault in distribution network, we develop a risk-based method to assess the financial risks caused by quality regulation for DSOs. Furthermore, in order to take the stochastic behavior of the distribution network and quality indices variations into account, time-sequential Monte Carlo simulation method is used. Using the proposed risk method, the effect of taking reclosing time into account will be examined on system quality indicators and the cost of quality regulation in Swedish rural reliability test system (SRRTS). The results show that taking reclosing fault into consideration, affects the system quality indicators, particularly annual average interruption frequency index of the system (SAIFI). Moreover taking reclosing fault into consideration also affects the quality regulations cost. Therefore, considering reclosing time provides a more realistic viewpoint about the financial risks arising from quality regulation for DSOs.

This study investigated the effects of maternal parenting behaviors and preschooler's emotional regulation on their internet-game addictive inclination. The participants were 129 mothers of 5 and 6 year-old preschoolers and their teachers from two day dare centers and one kindergarten in Seoul and Kyung-gi province. Data were analyzed by descriptive statistics and hierarchical regressions by SPSS program (12.0 version). The major findings were as follows: (1) Boys showed higher score of internet-game addictive inclination than that of girls. (2) mother's consistent parenting behaviors and preschooler's other-regulation behaviors significantly explained preschooler's internet-game addictive inclination. In conclusion, maternal parenting behaviors and preschooler's emotional regulation have influenced on preschooler's internet-game addictive inclination.

Relations of regulation, negative emotionality and problem behaviors to school adjustment were examined for 1,105 elementary school children from 558 2nd grade and 547 5th grade. Children reported their regulation and negative emotionality and teachers rated children's problem behaviors such as hyperactive and withdrawal behaviors and school adjustment including school life, grades, social competence with peers and teacher. Measures of problem behaviors were highly contributed to the prediction of children's school adjustment, especially hyperactive to school life and grades and withdrawal to social competence with peers and teacher. Behavioral regulation was associated with school adjustment including school life and social functioning with teacher and was able to modulate the influence of hyperactive. It was found that depression had both direct and indirect effects via withdrawal behavior on school adjustment.

The purpose of this study was to investigate the effect of mother's smartphone dependency and maternal guilty feelings on early childhood emotion regulation. The subjects were 326 mothers of 2 to 5 year olds. Mothers' smartphone dependency was assessed by the Korea Agency for Digital Opportunity & Promotion(2006), guilty feelings by the Maternal Guilt Scale(Sung 2011), and early childhood emotion regulation assessed by the ERC(Park 2012). The results of the study were as follows. First, mother's dependency on smartphones was highly related with early childhood emotion regulation. Maternal guilty feelingswere weakly related with child's emotion regulation. Relationship between mother's dependency on smartphones and maternal guilty feelingswasmoderate. Second, mother's positive expectations towardssmartphones and maternal guilty feelings from negative parenting behavior explained early childhood emotion regulation as much as 69%.

This paper describes the use of a discrete mathematical model to represent the basic mechanisms of regulation of the bacteria E. coli in batch fermentation. The specific phenomena studied were the changes in metabolism and genetic regulation when the bacteria use three different carbon substrates (glucose, glycerol, and acetate). The model correctly predicts the behavior of E. coli vis-a-vis substrate mixtures. In a mixture of glucose, glycerol, and acetate, it prefers glucose, then glycerol, and finally acetate. The model included 67 nodes; 28 were genes, 20 enzymes, and 19 regulators/biochemical compounds. The model represents both the genetic regulation and metabolic networks in an integrated form, which is how they function biologically. This is one of the first attempts to include both of these networks in one model. Previously, discrete mathematical models were used only to describe genetic regulation networks. The study of the network dynamics generated 8 $(2^3)$ fixed points, one for each nutrient configuration (substrate mixture) in the medium. The fixed points of the discrete model reflect the phenotypes described. Gene expression and the patterns of the metabolic fluxes generated are described accurately. The activation of the gene regulation network depends basically on the presence of glucose and glycerol. The model predicts the behavior when mixed carbon sources are utilized as well as when there is no carbon source present. Fictitious jokers (Joker1, Joker2, and Repressor SdhC) had to be created to control 12 genes whose regulation mechanism is unknown, since glycerol and glucose do not act directly on the genes. The approach presented in this paper is particularly useful to investigate potential unknown gene regulation mechanisms; such a novel approach can also be used to describe other gene regulation situations such as the comparison between non-recombinant and recombinant yeast strain, producing recombinant proteins, presently under investigation in our group.

This study examines the effects of consumer socialization on Korean adolescent impulsive buying behavior. The current study used the third and sixth waves from the Korean Education and Employment Panel (KEEP) survey that has been administered by the Korea Research Institute for Vocational Education and Training since 2004. The subjects were high school juniors and university sophomores in 2006 and 2009, respectively. The final sample for panel regression analysis included 1,718 individuals. Two major agents of socialization (school and parents) were utilized in our model. Parent financial behavior (if the parents had savings) and the effectiveness/helpfulness of economics education in middle or high school were included in our estimation model. Two categories were included as individual factors: (1) psychological aspects and personal traits covering variables such as stress from self-image, academic stress, self-regulation, and a tendency of risky behavior and (2) financial behavior and attitudes, which include work experience, amount of money in hand, shopping habits, and if parental financial support is expected after high school graduation. The results from a random effects model revealed that the effects of consumer socialization through school was marginally significant, while through parents was not. Stress from self-image and the level of self-regulation were found to be significant. Neither risky behavior nor academic stress were a significant factor for impulsive buying behavior. The amount of money available in hand and shopping habits showed a significant influence. Implications for educators, parents and policy makers are identified.

Bus manufacturers have tested and studied the dynamic collapse behavior of a bus body structure in rollover since UN ECE established ECE Regulation 66 to provide the requirement for the strength of bus structure. In spite of the costly cycles of practical tests, however, it is still a hard task to meet the rollover regulation by means of local reinforcements in the bus structure. Therefore it is necessary to develop a well designed strategy for the rollover strength implemented in the early stage of vehicle development. In this study, the suitable development method for each design stage from a component to complete body structure was considered to make a well-established development process of a bus body structure for rollover safety. For the efficient approach of the concept design stage, a numerical model based on the plastic hinge theory was used instead of detailed shell models. After setting up the concept design for the component size and geometry, the shell model was used to confirm and optimize the whole structure composition. The process developed in this study was practically used as an effective method to predict the rollover behavior of a new bus body structure.
