The purpose of this study is analysis of 52 dissertations on assertiveness training which presented from 1982 to 1997 in Korea. It was diversified the research purpose to by 1) time of publication or presentation 2) research design, characteristics of subjects used in each study 3) related concepts, the effects of nursing interventions according to related concepts 4) the effects of nursing interventions according to the subjects 5) the effects of nursing interventions according to the frequency and the period of assertiveness training 6) the effects of nursing interventions according to the group size. 7) the effects of nursing interventions according to the necessary time per round. Findings obtained in the study were as follows : 1. At the point of the numbers of studies presented by year, the number of the studies tend to increase, especially the most plentiful papers were presented during five years from 1991 to 1995. 2. Research design of the studies belong to experimental research. The subjects of research consists of 5 Nursing related subjects and 47 Non-nursing related subjects so that Non-nursing related subjects contain much large proportion. 3. When studies were classified by the related concepts, they were classified that 17 studies were by assertiveness & assertive behaviour, 15 ones anxiety, 9 ones self & ego, 7 ones depression. It can be inferred that studies related to assertive behaviour, self & ego, sociality and power of learning were increasing. Otherwise, studies related to anxiety, depression, aggression, shyness and anguish were decreasing. 4. At the point of the nursing intervention effect by the subjects, the concepts of assertive behavior, feeling of self-respect and sociality were increasing, but the concepts of conflict and interpersonal stress were decreasing and the concepts of anxiety and sociality were ineffective in the subjects related Nursing. On the contrary, the concepts of assertive behavior, sociality and personalty were increasing, but the concepts of anxiety, depression, aggression, shyness, self-estranged feeling were decreasing and the concepts of assertive behavior, aggression, personalty, power of learning, anxiety, self-concepts and self-expression were ineffective in the subjects related Non-Nursing. 5. 18 studies can be found, which investigated 10 times for 5 weeks from the point of the nursing intervention effect by the times and the period of assertiveness training. In case of over 5 times of assertiveness training, assertiveness, assertive behavior and personality(tranquility, depression) increased. In 6 times, feeling of self-respect & egorespect increased but depression, interpersonal stress and anxiety decreased. In over 10 times, shyness, shame and feeling of self-estrangement decreased. In over 12 times, interpersonal anxiety decreased. 6. In the event of nursing intervention effect by the size of the group, it was greatest within 10 persons in 21 studies. In case of within 10 to 20, only feeling of self-expression were ineffective. Particularly, in case of over 31 persons, there were no ineffective concepts. 7. At the viewpoint of nursing intervention effect by the necessary time of one time, it was greatest within 1 to 2 hours in 32 studies. In case of within 1hour, aggression, power of learning and assertiveness were ineffective. In case of within 1 to 2 hours, assertive behavior, self-expression, personality and anxiety were ineffective. Particularly, in case of within 2 to 3 hours, there were no ineffective concepts.

The purpose of this study was to develop a standardized scale to measure consumers' motivation to purchase based on a self-determination theory. A preliminary 27-item scale was developed through literature review, diary analysis, and FGI. A questionnaire survey was conducted among 1,000consumers on internet using the preliminary scale. Then a series of tests, such as test-retest, item analysis, item-to-total correlation, Cronbach's reliability coefficient, and factor analysis, were conducted using the survey data. The final scale with21 items was constructed in the end. The Purchase Motivation Scale for Consumers consisted of five factors: (1) external motivation, (2) introjected motivation, (3) identified motivation I: self-respect, (4) identified motivation II: pursuit of harmony, and (5) internal motivation.

The purpose of the study was to examine the effects of the reciprocal peer tutoring in high school students' affective characteristics with respect to mathematics. The study was conducted with 111 first graders in one high school located in Gyeonggi-do, and the study lasted for 1 year in regular mathematics classrooms. According to the results, reciprocal peer tutoring was very effective in improving students' interest and self-efficacy toward mathematics and reducing mathematics anxiety. Especially, in high and low performing student groups, there were statistically significant improvements in affective factors such as interest, self-efficacy toward mathematics, and mathematics anxiety after reciprocal peer tutoring. However, average performing student group showed statistically significant improvements in affective factors of interest and self-efficacy toward mathematics.

A self-sensing magnetic suspension system utilizing a LC resonant circuit is proposed by using the characteristic that the inductance of the magnetic system is varied with respect to the air gap displacement. An external capacitor is added into the electric system to make the levitation system be statically stable system, which much relieves the control effort required to stabilize the magnetic suspension system of haying an intrinsic unstable nature. For the realization of the self- sensing magnetically levitated system, an amplitude modulation / demodulation method is used with a positive position feedback controller Experimental results are presented to validate the proposed method.

This research examined the psychological characteristics of children, such as children's attachment to their mothers, self-concept, daily stress, and depression, in both multicultural and typical Korean families. Elementary school children in 3rd to 6th grade were surveyed in Chunnam province. 158 cases of multicultural families and 181 cases of typical Korean families were analyzed by the methods of Cronbach's a coefficient and independent t-test using SPSS program. Children from multicultural families had less attachment to their mothers and self respect than those from typical Korean families. Regarding daily stress, children from multicultural families highly recognize the economic and physical environments, whereas children from typical Korean families highly recognize the academic achievements and the relationships with their teachers. Children from multicultural families were highly prone to depression compared to the children from typical Korean families.

Predicting fracture properties requires an understanding of structural failure behaviour in relation to specimen type, dimension, and notch length. Facture properties are evaluated using various testing methods, wedge splitting test being one of them. The wedge splitting test was numerically modelled three dimensionally using the finite element method on self compacting concrete specimens with varied specimen and notch depths in the current work. The load - Crack mouth opening displacement curves and the angle of rotation with respect to notch opening till failure are used to assess the fracture properties. Furthermore, based on the simulation results, failure curve was built to forecast the fracture behaviour of self-compacting concrete. The fracture failure curve revealed that the failure was quasi-brittle in character, conforming to non-linear elastic properties for all specimen depth and notch depth combinations.

Objective: The adhesion capabilities of different types of self-ligating brackets were measured with respect to Streptococcus mutans and Streptococcus sobrinus. Methods: Five types of self-ligating brackets (Clippy-C; Mini Clippy; Clarity-SL; Speed; Damon 3) were used for the experiment group and composite resin brackets (Spirit-MB), metal brackets (Victory) and polycrystalline alumina brackets (Clarity) were used for the control group. In order to assess adhesion of bacteria to the brackets, the brackets were cultured for 3, 6 and 24 hours in media containing bacteria and 20% sucrose. Results: There was no statistic difference in adhesion amount of Streptococcus mutans and Streptococcus sobrinus according to the types of brackets. A total adhesion amount according to bracket type was different. An extended incubation time increased adhesion amount. Observation under scanning electron microscope showed that Streptococcus sobrinus adhered more to Clippy-C and Victory rather than to Clarity-SL. Conclusions: Clarity-SL, a self-ligating esthetic bracket was confirmed to show lower bacterial adhesion to cariogenic bacteria, Streptococcus mutans and Streptococcus sobrinus group than other self-ligating brackets or conventional brackets, which suggests that proper use of self-ligating esthetic brackets might even be better in preventing tooth surface decalcification.

This study investigated the self-related and parental factors that influence depression in 204 adolescents from a low social economic status background. The self-related factors were self-trust and emotional regulation, and the parental factors were parental concern and domestic violence. The results showed that girls were more likely to be depressive, but had better emotional regulations and a closer relationship with their parents than boys. There was no significant difference between age groups with respect to parental concern, self-trust and emotion regulation. It was also found by regression analyses that girls' depression was predicted by both emotional regulation and parental concern while boys' depression was predicted only by self-trust. The finding suggested that intervention for boys' depression has to focus more on intrapersonal factors, but should emphasize interpersonal factors for girls.

This study aimed to establish and validate the path models among faculty-student interaction, self-directed learning, and institutional commitment which impacted on the academic achievement of the university students. To achieve these goals, the survey results from 488 university students in North Gyungsang Province were analyzed. Descriptive analysis, correlation analysis, t-test, and path model analysis were performed to understand the relationship among variables. First, all the variables showed positive correlations except academic achievement and institutional commitment upon the study results. Second with respect to the differences by groups, faculty-student interaction and institutional commitment demonstrated the significant differences by sex while self-directed learning and academic achievement did not. Third on the path analyses, self-directed learning influenced to academic achievement directly, while faculty-student interaction did to it by mediating with self-directed learning and institutional commitment. The results of this study suggest that faculty-student interaction, self-directed learning, and institutional commitment perceived by the university students were significant elements on their academic achievements.

Purpose: This study investigates the controlling effect of self-efficacy in the relationship between the happiness and loneliness of hospice volunteers. Methods: The subjects of this study were 120 hospice volunteers in G City. This study uses the happiness scale that Lee and Yu developed, the loneliness scale that Russell revised and Park translated, and Bandura's self-efficacy scale. The collected data were analyzed with frequency, ANOVA, and hierarchal regression by using SPSS 12.0. Results: The happiness scale of the subjects, based on general traits, was significant in occupation and image. The loneliness scale was significant in monthly income. The self-efficacy of the subjects was significant in monthly income, occupation, and hobby. The happiness of the volunteers affected loneliness. With respect to the relationship between the happiness and loneliness of the volunteers, self-efficacy did not have controlling influences. Conclusions: The results suggest that happiness can affect loneliness without the controlling influence of self-efficacy. As such, it would be beneficial to develop programs that can improve the happiness of hospice volunteers.
