Doping effects and semiconductor behaviors of the dispersed p- and n-Si, p- and n- GaAs particles in the aqueous electrolyte have been studied using microelectrophoretic, voltammetric and chronoamperometric techniques. The cations (K$^{+}$) are adsorbed on both the p- and n- Si particle surfaces regardless of the sign of space charges in the depletion layers, i.e. doping profiles. The surface states are negatively charged acceptor states. On the other hand, the anions (CI$^{-}$) are adsorbed on both the p- and n- GaAs particle surfaces regardless of the sign of space charges in the depletion layers, i.e. doping profiles. The surface states are positively charged donor states. Under the same conditions, electrophoretic mobilities, electrochemical processes, doping effects and related semiconductor behaviors of the Si and the GaAs particles are similar regardless of the doping profiles, i. e. dopants and doping concentrations. The doping effects and related semiconductor behaviors of the dispersed p- and n- type semiconductor particles are gradually lost with decreasing dimensions.

The goal of this research was to clarify how a child's maladjustment affects the teacher-child relationship and leads to teaching stress. Subjects were 178 teacher-child pairs in kindergartens or day care centers. The child was 3 to 5-years-old and perceived by its teacher as having maladjusted behavior. Teachers responded to the Index of Teaching Stress(Greene, Abidin, & Kmetz, 1997) and the Student-Teacher Relationships Scale(Pianta 1991). The maladjusted behaviors observed by teachers were correlated with each other. ADHD was the biggest problem perceived by teachers. Most fields of maladjusted children's behaviors caused stress to teachers except those of intellectual deficit and academic Problems. Frustration peaked during the teaching process. More severely maladjusted behaviors resulted in greater conflict in teacher-child relationships.

Information about the mating behaviors of an endangered species is critical for the understanding of the natural history of the species as well as in situ and ex situ breeding programs designed to rehabilitate field populations. We describe the mating behaviors of the Mongolian racerunner (Eremias argus), an endangered species in South Korea. The mating of this species consists of precopulatory, copulatory, and postcopulatory stages and is composed of 12 different mating behaviors. During the postcopulatory stage, other males or females not involved in mating show more interference behaviors than during the precopulatory and copulatory stages. The male E. argus has an extraordinarily long postcopulatory bite, which may function as a type of mate-guarding behavior. This study is the first report on the mating behavior of a South Korean reptile.

Customer misbehavior can affect dissatisfaction and negative behavioral responses of other customers at the service encounter. This study explored other customer and retail employee reponses to customer anger and aggressive behaviors at the service encounter by examining the perceived wrongness of such behaviors under different situations and comparing the two perspectives of retail employees and consumers. Three scenarios were developed representing different situations including firm's responsibility, both of customer and employee responsibilities, and uncontrollable one. Data were collected from individual interviews with 222 retail employees and 149 consumers. The results showed that the consumers' perceived wrongness of customer aggressions were higher comparing to that of employees. The reasons of perceived wrongness were different by three situations implying that responsibility and controllability affected the perceived wrongness. The study further discusses implications.

Mobile social network can be seen as a specific application of the DTN (Delay Tolerant Network), in which the information propagation can be impacted by many social behaviors of the nodes. For a specific node, its social behaviors are various. For example, the node may not be interested in the information before receiving it and may also discard the information after getting it. On the other hand, people are more willing to forward the message to his friends. These interactive behaviors between nodes can be seen as social behaviors. It is easy to see that the impact of the social behaviors is related to the social ties, which can be manifested by the structure of the social network. State of the art works often simply assumes that the social networks can be divided into some communities. At present, some works find that the structure of some social networks is scale-free. To overcome this problem, this paper proposes a theoretical model to evaluate the impact of above social behaviors in the DTN-like scale-free network. Simulation shows the accuracy of the model. Numerical results show that both social behaviors and scale-free character have significant impact on information propagation. Moreover, the impact of social behaviors is related to the scale-free character of the networks.

The purpose of this study was to examine the level of concern and the level of knowledge of endocrine disruptors, and the level of dietary behaviors to decrease exposure to endocrine disruptors, to determine the factors affecting the level of knowledge and behaviors, and to assess the causal relationship between them. The data were collected from 579 adults in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju provinces. Frequencies, t tests, analysis of variance, Cronbach's alpha, Pearson's correlation coefficient analysis, multiple regression analyses, and path analysis were carried out by SPSS for Win V.18.0. The results of this study were as follows: The level of concern about endocrine disruptors was higher than the medium level. The respondents were most concerned about a container of cup ramen among products related to foods. The levels of both knowledge and behaviors in order to decrease exposure to endocrine disruptors in dietary life were not high. The factors affecting the level of knowledge of endocrine disruptors were educational level, attendance in education for endocrine disruptors, and concern about endocrine disruptors. On the other hand, sex, age, concern about endocrine disruptors, and the level of knowledge of endocrine disruptors affected the level of behaviors to decrease exposure toward endocrine disruptors. The results of the path analysis showed that educational level and education of endocrine disruptors had an indirect influence on the level of behaviors in order to decrease exposure to endocrine disruptors in dietary life. The concern about endocrine disruptors had both a direct and an indirect effect on the level of behaviors to decrease exposure to endocrine disruptors in dietary life. In addition, sex, age and the level of knowledge of endocrine disruptors directly affected the level of behaviors to decrease exposure to endocrine disruptors in dietary life.

It is very important to understand system behaviors in collective pattern for each knowledge domain. However, there are structural limitations to represent collective behaviors because of the size of system components and the complexity of their interactions, causing the state explosion problem. Further composition with other systems is mostly impractical because of exponential growth of their size and complexity. This paper presents a practical method to model the collective behaviors, based on a new concept of domain engineering: behavior ontology. Firstly, the ontology defines each collective behavior of a system from active ontology. Secondly, the behaviors are formed in a quantifiably abstract lattice, called common regular expression. Thirdly, a lattice can be composed with other lattices based on quantifiably common elements. The method can be one of the most innovative approaches in representing system behaviors in collective pattern, as well as in minimization of system states to reduce system complexity. For implementation, a prototype tool, called PRISM, has been developed on ADOxx Meta-Modelling Platform.

This study was undertaken as a useful material not only to understand the clothing behaviors and the personal variables (age, education, occupation, yearly clothing expenses, weight, and persons who influence on one's choice of clothes) of the middle-aged women in Seoul, Korea but to lend itself to other uses concerning attitudes toward clothing. For the measurement of the attitudes toward specified activities related to clothing use, attitude method by Mary F. Pasnak (1968) was reworded and modified for use with the sample for this study. Analysis of the data revealed that the clothing behaviors of 450 women 30 to 59 years of age made a significant difference according to the personal variables. First, women in thirties showed the most positive clothing attitude of the three age groups. The younger age groups were positively related to relief from boredom through clothing, intensity, sureness, and involvement of attitude among eight attitudes related to clothing. Second, the positiveness of relief from boredom through clothing, intensity, sureness, and involvement of attitude increased in proportion to the education level. On the other hand, dressing for self was negatively related to the level of education. Third, a significant relationship was found between the amount of the clothing expenses and dressing for others, tactual pleasure through clothing, intensity, sureness, and involvement of attitude. Among the personal variables of the middle-aged women, age, the educational level, and the clothing expenses have a relationship with the clothing behaviors, while job, weight, and the persons who influence on one's choice of clothes have no relationship. The extensive interpretation on the result of this study will have to be taken with deliberation. For the more practical material researches on the clothing behaviors of the middle-aged women should be continued steadily in every possible way.

The purpose of this study was to investigate the appearance management behaviors and motives differentiated by the body image of college men. A questionnaire was designed for the survey and the subjects were 228 college in Pusan and the Kyongnam province, Korea. The statistical analyses were carried out in the forms of frequency, factor analysis, cluster analysis, ANOVA and Duncan's multiple range test. The findings throughout the research are as follows; First, according to the multidimensional body image of the subjects, the college men were classified into three groups, i.e. the appearance concerning and satisfied group, the weight concerning group, and the appearance indifferent group. The appearance management behaviors of the college men consist of innovative appearance management, weight reduction, appearance management through apparel and fashion products, body shape care, skin care, hair care and health care. Second, the weight concerning group showed a higher BMI than those of the other groups. The means of the monthly income and the expenses for the appearance management of the appearance indifferent group were lower than those of the other groups. Third, the college men were generally shown to pursue the motive improving sociality. The appearance concerning and satisfied group and the weight concerning group indicated higher pursuing motives than the appearance indifferent group in the appearance management motives. Finally, there were significant differences in the appearance management behaviors among the three groups. While the weight concerning group showed the more concerning appearance management behaviors, the appearance indifferent group had the least appearance concerning tendency.

The purpose of this study was to examine beliefs, self-efficacy and eating behaviors by the stages of change in vegetable consumption among college students (n = 297). A survey was conducted to examine study variables, and subjects were categorized into three groups based on the stages of change: precontemplation/contemplation stage (PC/C), preparation stage (P), action/maintenance stage (A/M). Subjects had 3.7 servings of vegetables a day, and vegetable consumption was significantly different by stages of change (p < 0.001). The A/M group showed higher score on beliefs regarding vegetable consumption (p < 0.001) than the other groups, and perceived benefits of vegetable consumption (e.g. cancer prevention) more strongly (p < 0.05). The PC/C group felt more barriers than the A/M group, such as disliking cooking methods, texture of vegetables (p < 0.001), bad taste and bad experience of eating vegetables (p < 0.05). Self-efficacy score was 27.2, with decreasing self-efficacy from A/M to P, PC/C (p < 0.001). The A/M group showed more confidence in nine behaviors such as "eating vegetables during meals" and "replacing menu at home with more vegetable dishes" (p < 0.001) than the other groups. The A/M group had more desirable eating behaviors (e.g, having a variety of foods, eating regularly, consumption of food groups). This study suggests that target population for education and educational strategies be different based on the stages of change. For those in the PC/C stage, education might focus on reducing barriers and increasing self-efficacy. For those in the A/M stage, it is necessary to use strategies to maintain and reinforce behaviors for enough vegetable consumption.
