People tend to perceive their loved others (e.g., children, spouse, romantic partner) as their extended selves and then control over the loved others' fashion style corresponding to their self-concept. The study conceptually suggested that people's perceptions on legitimacy to interfere the others and their own fashionability would separately or interactively influence their control over the loved others' fashion style. To investigate the suggestions, an experiment with female participants in their 20's was conducted by using a scenario. The results indicated that participants' perception of legitimacy to interfere their boyfriends or their own fashionability did not have a separate effect on control over their boyfriends' fashion style. However, the legitimacy and the fashionability did have an interactive effect on the control. In particular, for high legitimacy groups, there was no difference in the control between low and high fashionability groups. For low legitimacy groups, the control was stronger in high fashionability group than in low fashionability group.

Low cost motor drives are being sought for high volume energy efficient home appliances. Key to the realization of such low cost motor drives is to reduce the power electronic converter in terms of its components, particularly the active devices, finding the motor with least complexity for manufacturing and a controller that could extract the desired performance from the machine and converter combination. These and other factors such as self-starting, speed control over a wide range and most of all the crowning aspect of a four quadrant operation with bare minimum number of controllable switch (or switches) remain as formidable challenges for low cost motor drive realization. In this paper, a four quadrant switched reluctance motor (SRM) drive with only one controllable switch is realized by using a two-phase machine. The theory and operation of the proposed four-quadrant SRM drive with the proposed control algorithm for its realization are described. The motor drive is modeled, simulated and analyzed to verify its feasibility for self-starting, speed control and for four quadrant operation and the simulation results are presented. Experimental results confirm the validity of the proposed control algorithm for four quadrant control of the SRM drive. The focus of the paper is mainly directed toward the control algorithm for realizing the four-quadrant operation of the two-phase SRM drive with a single controllable switch converter.

Purpose: This study is a descriptive correlation study to identify how factors such as motivation to learn, school adaptation, self-control, and self-esteem influence the degree of Internet game addiction and to provide basic data for nursing interventions for male middle school students. Methods: The subjects of this study were 418 male students in lst, 2nd and 3rd grade at three middle schools located in Ulsan. Data were collected from May 1, 2011 to May 31, 2011 and analyzed through descriptive statistical methods, such as the t-test, ANOVA, Sheffe's test, Pearson correlation coefficient and multiple regression analysis, via SPSS 18.0 program. The study's structured questionnaire was composed of 25 items of 'the Motivation to Learn Scale', 41 items of 'the School Adaptation Scale', 20 items of 'the Self-Control Scale', 10 items of 'the Self-esteem Scale', and 20 items of 'the Internet Game Addiction Scale'. Results: 163 students (39.0%) belonged to the non-addiction group while 255 students (61.0%) fell into the addiction risk group. The addiction risk group showed a higher degree of addiction than ones in the non-addiction group. The addiction risk group's average scores for motivation to learn, school adaptation, self-control, and self-esteem were lower than those of the non-addiction group. The statistically significant factors (p<.05) that increase the chance of addiction were grade, family atmosphere, self-control, trading of online game items, and the amount of time playing online games. Conclusion: On the basis of the findings of this study, it is suggested that; qualitative research on the routes of addiction be conducted to find out ways to prevent and nurse addicted students; considering the fact that the average age of Internet users is getting lower and lower, a study targeting primary school students be implemented; since the influences of the variables covered in this study turned out to be relatively low, other factors, especially environmental factors, should also be investigated.

In this paper, Asynchronous Self-Power Gating technique (ASPG) is used to reduce consumption power in asynchronous digital watch application. The power gating control signal is automatically generated by internal system operation characteristics instead of using replica circuit delay or four-phase handshaking protocol. Isolation cell is designed to insert it between power gating domain and normal operation domain. By using self-power gating circuit, asynchronous digital watch application consumes very low power and maintains data during sleep mode. The comparison results show the proposed ASPG technique saves leakage power up to 40.47% and delay time is reduced to 71% compared to the conventional circuit.

This study aimed to demonstrate 'moderated mediation' effect of self-control on the relationship of neuroticism-smart phone addiction-school adaptation. For this purpose, we carried out a survey targeting middle school students who were vulnerable to smart phone addiction, and 1,400 middle school students responded to questionnaire. The results showed that the moderated mediation effect of self-control was statistically significant. In detail, school satisfaction and school performance, the sub-factors of school adaptation, showed significant results but social relation non-significant. Concerning moderating effect of self-control, results supported significantly moderating effect, demonstrating that high level of self-control showed consistently lower level of smart phone addiction than low level of self-control regardless of level of neuroticism. We can find the meanings of this study in having demonstrated, on the one hand, the causal process of smart phone addiction, and on the other, moderating effect and moderated mediation effect on this causal process through interaction between neuroticism and self-control. Finally, limitations and suggestions for future research were discussed.

A 32-b self-timed parallel carry look-ahead adder (PCLA) designed for 0.5.mum. single threshold low power CMOS technology is demonstrated to operate with 2.7nsec delay at 8mW under 1V power supply. Compared to static PCLA and DPL adder, the self-timed PCLA designed with NORA logic provides the best performance at the power consumption comparable to other adder structures. The wave pipelined clock control play a crucial role in achieving the low power, high performance of this adder by eliminating the unnecessary power consumption due to the short-circuit current during the precharge phase. Th enoise margin has been improved by adopting the physical design of staic CMOS logic structure with controlled transistor sizes.

The purpose of this investigation was to examine the mediating effects of delinquent peers between attachment to parents, low self-control and adolescent deviant behaviors. After specifying a research model based on Gottfredson and Hirschi's general theory of crime and Hirschi's control theory of delinquency, the study analysed the model using structural equation modeling. The data for this investigation came from a sample of 2,448 Korean adolescents. The results showed the both measurement model and structural model had a good fit to the data and all paths of structural model were statistically significant. The main findings were the attachment to parents and low self-control had direct and indirect effects on adolescent deviant behaviors through delinquent peers. The implications for practical intervention and further research in the field of delinquency were discussed.
