Objective: The purpose of this study is to present a detailed view of the self-regulation of 5-year-old children based on parental attitudes and consistency. Methods: The research was conducted among 144 pairs of parents (288 people) of 5-year-old children residing in Seoul. Results: The resultsare as follows. First, with regards to self-regulation based on a child'sgenderand mother's parental attitudes, sub-factors such as parental attitudes and parental interaction were found to have significant effects on self-determination. Also,parental attitudes and parental interaction were found to have significant effects on the sub-factors of self-monitoring, such as self-evaluation and self-determination and the sub-factors of self-regulation, such as behavioral inhibition and emotionality. Second, the percentage of parents whose parental attitude was consistent at 58.3%, which is higher than the percentage of parents whose parenting attitude was inconsistent at 41.7%. The results of self-regulation were significantly higher when parental attitudes were consistent than when they were inconsistent. Conclusion/Implications: This research is significant in that it offered a concrete view of parental attitudes and consistency status that affect child's self-regulation.

Since Michael Porter (1991) has proposed that environmental regulation can help a firm increase its competitiveness by encouraging it to engage in more innovative activities to meet the environmental regulation, a number of researchers have empirically investigated the "Porter Hypothesis." However, the empirical results still remain mixed. Combining the perspectives of the behavioral theory of the firm and firm heterogeneity, we argue that the levels of regulation stringency and time-pressure would differentially influence a firm's innovative behavior depending on the firm's aspiration level, performance feedback and technological capabilities. Using the U.S. Corporate Average Fuel Efficiency (CAFE) regulation context, we empirically demonstrate that lagging firms that do not meet the new regulation standard announced by the government tend to search for more distant knowledge and that the impact of the patents they file for decreases as the regulation becomes more stringent. In addition, we also find that as time-pressure increases, lagging firms stand to apply for more patents than do leading firms whereas the overall impact of the patents decreases. These results help us advance our understanding of the nuanced causal relationship between regulation and innovation and provide practical implications for policymakers.

Methamphetamine is a powerful stimulant that appears to produce locomotor activity and behavioral sensitization. Previous study has indicated that dopaminergic receptors are implicated in the behavioral responses of methamphetamine. Recently, it has been reported that other receptors, especially, M1 muscarinic acetylcholine receptor (M1R) plays an important role in the regulation of behavioral responses, and this receptor is abundantly expressed in brain regions, including the cerebral cortex, striatum, and the hippocampus of the animal.

As Online Behavioral Advertising is dramatically growing with usefulness of information and user convenience in recent years, there are privacy issues caused by collecting user's behavioral information without their consent. To tackle the problem, the need of Do Not Track regulations is getting much higher. In Korea, however, it has never existed. So, this study is examining the case of the major countries have been enforcing the law and regulations of DNT. After that, it is classified with four domain (law/regulation, corporation, individual, society) to include all stakeholders of OBA. Furthermore, this study may have academic significance by suggesting DNT framework through analysis of them. Providing DNT mechanism consisted of three type (behavioral information, control, DNT system), it can be useful guidelines for companies to support decision making as introduced DNT. As analyzed between DNT and stakeholders based on the study of OBA market, it will be useful basic material of OBA study later.

This study was conducted to understand the relationships among adolescents' academic personality types (APT), learning behavioral types (LBT) and self-determinative learning motivations (SDLM). Regarding the measuring tools, the U&I APT test developed by Man-kwon KIM and Jong-cheol HAN (2002) and the learning motivation test translated by Kyeong-jin MIN (2006) were used. The study collected data from a total of 237 adolescents. First, gender did not influence the APT and LBT, and in terms of the introjected regulation as in the SDLM, female students were observed to have greater than the male students. Second, the normative type as in the APT was understood to have an identified regulation, an integrated regulation and an internal motivation as in the SDLM higher than those of the behavioral type or ideal type. Third, the normative type would be less rebellious and work harder to achieve a goal compared to the other types. Fourth, when adolescents have this motivation more voluntary and internal, they pursue greater goals for themselves, trying harder to fulfill their goals. The SDLM appeared to be related to most of the LBT.

Neural regulation of phenylethanolamine N-meth-yltransferase (PNMT) was studied with reserpine as a neuronal agent in rat adrenal medulla. The enzyme activity assay and northern blot analysis were performed to determine whether the induction of PNMT activity after reserpine treatment was associated with elevation of mRNA coding for PNMT. The i.p. administration of reserpine (2.5 mg/kg) on alternate days fot 4 injections to rats brought about 30% increase of adrenal medullary PNMT activity and approximately 60% stimulation of the PNMT mRNA level in rat adrenal gland. A dose of 10 mg/kg of reserpine was chosen to perform optimum induction of PNMT activity in the rat adrenal gland based on the results of dose response curve of reserpine. Time course reserpine (10 mg/kg) effects on the rat adrenal medullary PNMT were as follows: 1. Peripheral PNMT activity reached maximum level after 7 days of drug treatment on alternate days. 2. Trans-synaptic stimulation by reserpine increased pretranslational activity of rat adrenal PNMT, but not translational activity. 3. Immunotitration of PNMT molecule after reserpine treatment indicated that reserpine produced an enzyme with greater antibody affinity than endogenous molecule in the rat adrenal gland.

A comprehensive program for children's leadership improvement by enhancing their self-esteem, empathy, communication competence and emotion regulation utilized core concepts and techniques or the Solution-Focused Model of Chung et al. (2005), Satir's Experiential Model(Chung, 2003), Cognitive-Behavioral Model (Kim, 2002) and problem-solving games (Chung & Kim, 2005). Twenty-six $3^{rd}$, $4^{th}$, and $5^{th}$ graders from public schools in Seoul participated in six 2.5 hour sessions and their mothers participated in two 2.5 hour sessions. All subjects received pre-, post- and follow-up tests. The results showed that children's self-esteem, empathy, communication competence, and emotion regulation increased as a result of this program and the effects lasted for at least three months after the termination of the program.

Most living organisms synchronize their physiological and behavioral activities with the daily changes in the environment using intrinsic time-keeping systems called circadian clocks. In mammals, the key molecular features of the internal clock are transcription- and translational-based negative feedback loops, in which clock-specific transcription factors activate the periodic expression of their own repressors, thereby generating the circadian rhythms. CLOCK and BMAL1, the basic helix-loop-helix (bHLH)/PAS transcription factors, constitute the positive limb of the molecular clock oscillator. Recent investigations have shown that various levels of posttranslational regulation work in concert with CLOCK/BMAL1 in mediating circadian and cellular stimuli to control and reset the circadian rhythmicity. Here we review how the CLOCK and BMAL1 activities are regulated by intracellular distribution, posttranslational modification, and the recruitment of various epigenetic regulators in response to circadian and cellular signaling pathways.

Objective: This study analyzed mother-child interactions in a stressful situation each second by mother's emotional regulation level. Methods: The study was conducted with 16 mothers and their 5-year-old children playing a teaching task for 15 min. During the interactions, the participants were videotaped and examined. Furthermore, qualitative analysis was used for analyzing mother-child interactions in detail by creating a situation that maximizes the stress and frustration of the mother and child. Results: The results showed that maternal humor and affection were significantly related to child positive emotion and that maternal coaching closely correlated with the child pride, pleasure, and whining. Additionally, maternal intrusive behavior showed a positive correlation with child anger. Lastly, mothers with higher levels of emotional regulation more often expressed affection to their children. They were more actively involved in the tasks and used fewer positive or negative directive expressions. Therefore, children of this group expressed more positive emotions. Conclusion: These findings suggests that programs improving parental emotional reaction and emotion regulation should be developed.

The purposes of this study were to explore the gender differences in children's behavior problems, emotional regulation and social support, and to investigate differences between boys and girls in the interrelationships between these kinds of variables. The participants were 189 children in 4 to 6 grades and their teachers from one elementary school in Seoul. The data were analyzed using descriptive statistics, t-test, Pearson's correlation, and multiple regression. The results were as follows: (1) There were statistically significant gender differences in the children's behavior problems, emotional regulation and social support. (2) Children's negative emotion explained boys and girls acting out problems and learning problems. Children's positive emotion regulation explained boys' and girls' shy-anxious and learning problems. Boys, who perceived less support from parents, displayed more acting out behavior, boys who perceived less supports from friends showed more shy-anxious behavior, and boys who perceived less supports from teachers exhibited more learning problems.
