This study investigated the relationship between maternal facilitative communication perceived by children and the social adjustment which was measured as pro-social behaviors and aggressive behaviors in children. Special attention was given to the mediating effect of the child's self-regulation on the relationship. The subjects, selected by convenience sampling method, were 193 fourth and fifth grade elementary school students. Data was analyzed through Pearson's correlation, reliability analysis, and multiple regression using the SPSS 12.0. The findings of the study were as follows. First, the mother's facilitative communication perceived by the child was positively associated with the pro-social behavior, while, it was negatively correlated with the aggressive behavior of the child. Second, the mother's facilitative communication had direct effect on the prosocial behavior and the aggressive behavior of the child. Third, the direct impact of facilitative communication on social adjustment was mediated by the self-regulation variable. Based on these findings, this study proposes strategies for the improvement of children's adjustment during late childhood.

The objective of this study was to investigate differences in clothing behavior and individual characteristics of female college students by their body cathexis and clothing attitude. The college students selected by random sampling were classified into four groups by their body cathexis and clothing attitude: positive congruity(positive body cathexis and clothing attitude, G1), positive incongruity(negative body cathexis and positive clothing attitude, G2), negative congruity(negative body cathexis and clothing attitude, G3), negative incongruity(positive body cathexis and negative clothing attitude, G4). The results were as follows: G1 was high in both public and personal self-esteem and self-image, extroverted, refined and impulsive. G2 were fashion opinion leaders, highly uneasy about society, highly impulsive, modem, peculiar, creative and introspective. G3 was highly uneasy about society, low in self-esteem, and less impulsive. G4 was low in both public self-esteem and fashion innovation, and avoided impulsive buying.

The purpose of this paper was to present the proximity of clothing to self(PCS) which is a subjective measure developed by Sontag and Lee(2004). PCS is the scale to examine the relationship between self and clothing. Since PCS scale was prepared for American consumers, it is necessary to verify the validity as a measure to Korean consumers. Consumers' quality of life are functionally related to satisfaction with all of life's domain and subdomains. Clothing in life facilitates the creativity and expressiveness to the wearer, especially to adolescent. The concept of bottom-up spillover effect developed by Lee et al.(2002) was adopted as research model. Data were gathered by surveying university students using convenient sampling, 419 questionnaires were used in the statistical analysis. It was proved that PCS scale was effective measure to Korean consumers. And also PCS scale could be a proxy indicator in view of the fact that clothing was deeply related to consumers' quality of life.

This study aims at examining how male college students' extent of mass media exposure affects their sociocultural attitude toward appearance and appearance orientation. It also investigates how these variables show difference depending on the individual's self-efficacy. For the study, data were collected from 397 male students by means of stratified random sampling. The results are as follows: 1. Male college students 'sociocultural attitude toward appearance was shown in two factors of appearance internalization and appearance awareness. Appearance orientation was shown in two factors of interest in appearance and interest in body weight. 2. Male college students were exposed to mass media in order of videos, movies, TV entertainment shows, music and movie magazines. The influence of video media was strong. 3. Male college students' extent of mass media exposure exerted indirect influence through sociocultural attitude toward appearance rather than exerting direct influence on appearance orientation. 4. Male college students' appearance orientation varied depending on the extent of self-efficacy, and higher self-efficacy showed higher appearance orientation and appearance attitude. Especially the group with higher self-efficacy showed higher appearance attitude when the extent of exposure to mass media increased.

The global ultrasonic system for the self-localization of a mobile robot consists of several ultrasonic transmitters fixed at some reference positions in the global coordinates of robot environment. By activating the ultrasonic transmitters, the mobile robot is able to get the distance to the ultrasonic transmitters and compute its own position in the global coordinate. Due to the limitation on the ultrasonic signal strength and beam width as well as the environmental obstacles however, the ultrasonic signals from some generator may not be transmitted to the robot. Thus, instead of activating the all ultrasonic transmitters, it is necessary to select some ultrasonic generators to activate based on the current robot position. In this paper, we propose a selective activation algorithm for self-localization with the global ultrasonic system. The selective activation algorithm gets the meaningful ultrasonic data at every sampling instants, which results in the faster and more accurate response of the self-localization than the conventional sequential activation. Through the self-localization and path following control, we verify the effectiveness of the proposed selective activation algorithm.

The control of the SRM(Switched Reluctance Motor) is usually based on the non-linear inductance profiles with positions. So determination of optimal switching angle is very different. This paper proposed that the determination method of turn-on/off angle in the SRM drives is to maintain the high torque, which is realized by using self-tuning control method. During the sampling time, a number of pulses from the encoder are checked by using micro-controller. And compared with pre-checked a number of pulses. After calculating difference between two data, turn-on/off angle moves forward or backward direction by using self-tuning method. The optimal turn-on/off angle is determined by iterating such a process and the maximum torque is maintained. Experimental results are provided to demonstrate the validity of the self-tuning controller.
