The psychiatry features of narcissism are molded by the outcome of a mismatch or lack of tension between the realistic self and the ideal self, and it is related to the problems of alienation. That is, the problems of alienation lead to the outcome of a mismatch between the realistic self and the ideal self by the unindividuality which lose a senses of the reality in all every things, and it make man to even more to give up the realistic self and to be alive powerlessness living. In this views, this study examined the relationship between narcissism and alienations or subfactors, and the concrete subscale of the Narcissistic Personality Scale which had a influence on the alienations to experientially investigate the relation between narcissism and alienations. Juveniles were administered both the Narcissistic Personality Scale and the Alienations Scale. The results showed a positive relationship between narcissism and alienations, and the alienations was influenced of the self-centeredness and the exploitation/Privilege subscale of the Narcissistic Personality Scale. Therefore, narcissists feel alienations too much, and the more a person has self-centeredness and exploitation/Privilege of narcissistic traits, the higher alienations is.

Mathematics Teaching Efficacy Beliefs Inventory (MTEBI) was translated into Korean and conducted among Korean pre-service mathematics teachers. The Korean-translated MTEBI consists of two subscales with 16 items. Personal Mathematics Teaching Efficacy (PMTE) subscale has 10 items and Mathematics Teaching Outcome Expectancy (MTOE) subscale has 6 items. The purpose of this study is to investigate the internal reliability and the construct validity of the Korean-translated MTEBI. The Cronbach alpha coefficient of Korean-translated MTEBI and its two subscales are respectively .87, .83, and .74 which imply that the instrument is reliable. The construct validity was achieved by performing factor analysis. Principal component solution with varimax rotation for the Korean-translated MTEBI was used in factor analysis and thus the best fit simple structure was obtained by two factors which correspond to the self-efficacy dimension and the outcome expectancy dimension of Bandura's self-efficacy theory.

The hot-firing tests of a subscale gas generator were successfully performed to investigate the effect of injector shape variation on discharge coefficients. The test results showed that discharge coefficients of fuel and liquid oxygen injectors remained nearly constant irrespective of variations of a mixture ratio and a chamber pressure. Especially, the discharge coefficient of the liquid oxygen injector was largely increased compared to the previous works.

Purpose: The purpose of this study was to examine the predicting factors of nursing work performance. Methods: The participants in this study were 148 nurses working in S university hospital in P city. The scales included social support, health promoting lifestyle profile-II (HPLP-II), and nursing work performance. A descriptive analysis and stepwise multiple regression were used for data analysis. Results: Significant correlations were found among social support, health promotion behaviors and nursing work performance. The significant predictive factors of nursing work performance were the emotional support subscale of social support (β=.31, p<.001) and the interpersonal relations subscale of health promotion behaviors (β=.32, p<.001). These two subscales explained 27% of nursing work performance. Conclusion: Nursing education programs should include an emphasis on developing methods of emotional support and interpersonal relations in order to improve nursing work performance among clinical nurses.

Objectives: In order to investigate the efficacy and safety of the newly developed herbal medicine Jetongdan, a placebo­controlled, randomized clinical trial of patients with osteoarthritis of the knee was undertaken. Methods: Data were obtained from 80 patients with OA of the knee. After enrollment, they were asked to answer a disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index) and analyzed with the erythrocyte sedimentation rate (ESR) in order to evaluate the efficacy of Jetongdan, and analyzed for aspartate transaminase (AST) level, alanine transaminase (ALT) level, blood mea nitrogen (BUN) level, and creatinine (Cr) level in order to evaluate the safety of Jetongdan. Results: The liver function and renal function did not deteriorate after treatment with Jetongdan. Composite WOMAC score and physical function subscale was improved, but pain subscale, stiffness subscale, and ESR were not improved by. This was possibly because the baseline characteristics of the two groups were not homogenized after randomization. Conclusions: Jetongdan could be a promising treatment option for osteoarthritis of the knee. Further study in a larger population with appropriate severity grades is recommended.

Purpose: The purpose of this study was to identify the degree of Job stress and Coping of the nurses in ICU and Cancer ward, and to compare the Job stress and Coping between two groups, and finally to get the basic information about the adequate method to promote Coping about Job stress of the nurses in ICU and Cancer ward. Method: The subjects of this study were 131; 62 nurses in ICU and 69 nurses in Cancer ward. Data were collected from 27th August to 14th September in 2007. The instruments for this study were Job stress scale(55 items) developed by Kim(1989), and Coping scale(32 items) developed by Lazarus and Folkman(1984) and revised by Han and Oh(1990). For the data analysis, SPSS PC/win 12.0 program was utilized for descriptive statistics, $X^2$-test, t-test, Pearson correlation. Result: The results of this study were the followings; The mean score of Job stress(range 1-5) was 2.93 in ICU nurse and 2.58 in Cancer ward nurse. There was a significant difference (t=4.453, p<.01)between them. There were significant differences in subscale of Job stress between the two groups, such as Nursing job(t=3.717, p<.01), Job circumstances(t=4.558, p<.01), Personal relations(t=3.425, p<.01), Hospital administration and ward management(t=2.94, p<.01). The mean score of Coping(range 1-4) was 2.55 in ICU nurse, and 2.54 in Cancer ward nurse; there was no significant difference. But one subscale of the Coping(Search of social support) showed significant difference(t=-2.865, p<.01). There was no significant correlation between Job stress and Coping of ICU nurse vs Cancer ward nurse except one subscale in cancer ward(correlation between Nursing Job and Coping). Conclusion: The ICU nurse is higher than the Cancer ward nurse in the Job stress score significantly and lower than the Cancer unit nurse in the Coping. Based on the study results, it is needed the program development using the Coping methods in accordance with ward speciality to relieve Job stress.

This study investigated the relationships between the husband's support, depression, parenting self-efficacy, and parenting behavior of Korean American mothers and their children's self-esteem. The participants were 113 Korean American child-mother dyads (grades 3-8) from Southern California, USA. The data, including the mothers' parenting behavior as assessed by their children, were collected from self-report questionnaires. A path analysis indicated that the effects of the above mentioned variables on the children's self-esteem depended on the subscale model of the parenting behavior. In every subscale model of parenting behavior, the husband's support was positively related to the parenting self-efficacy and the mother's depression was negatively related to the parenting self-efficacy. Further, in the warmth-acceptance model, the husband's support was positively related to the parenting behavior, the mother's depression was negatively related to the parenting behavior, parenting self-efficacy was positively related to both the parenting behavior and the children's self-esteem, and the parenting behavior was positively related to the children's self-esteem. In the rejection-restriction model, the husband's support was negatively related to the parenting behavior, the mother's depression was positively related to the parenting behavior, the parenting self-efficacy was negatively related to the parenting behavior and was positively related to the children's self-esteem, and the parenting behavior was negatively related to the children's self-esteem. In the permissiveness-nonintervention model, the parenting behavior was negatively related to the children's self-esteem. These results, particularly the dependence on the subscale model of parenting behavior, will be helpful in understanding the effects of parenting on Korean American children's self-esteem.

Objectives : This study was conducted in order to investigate the influence of sexual trauma on the psychopathology and quality of life of children and adolescents in Korea. Methods : Twenty-seven children and adolescents and their caretakers who visited the Kangwon Sunflower Center participated in a cross-sectional study. Participants completed the Korean version of Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version, Child Behavior Checklist (CBCL), and Child Health Questionnaire-Parent Form-50 (CHQ-PF-50). Their scores were compared with those of a age and sex-matched control group of 27 healthy children and adolescents. Results : Victims of sexual violence showed higher t score in Withdrawn, Social problems, Delinquent behavior, Externalizing problems, and Total problems in CBCL, compared with control group. In CHQ-PF-50, there were lower scores on Bodily pain/discomfort, Behavior, Mental health, Time impact in parents, and Family activities subscales in victims of sexual violence. While Behavior and Family activities subscale showed negative correlations with Delinquent behavior, Externalizing problems, and Total problems in CBCL. Mental health subscale showed negative correlations with Social problems, Delinquent behavior, Externalizing problems, and Total problems. In addition, Time impact on parent subscale showed a negative association with Delinquent behavior in CBCL. Conclusion : The current study provided evidence suggesting that victims of sexual violence had a higher level of psychopathology and lower level of quality of life.

The performance characteristics of a subscale diffuser under non-reacting conditions for high-altitude simulation were numerically investigated with respect to different lengths of the secondary throat diffuser. The ratio of the length of the diffuser entrance to the nozzle exit diameter was set to 0, 50, and 100%. In addition, flow characteristics were studied for a range of length-to-diameter ratios of the secondary throat diffuser. An insufficient diffuser entrance length caused contraction of the plume immediately after the nozzle exit. When the length-to-diameter ratio was less than 8, a strong Mach disk was formed inside the diffuser, resulting in a sharp increase in pressure. In addition, flow characteristics in the diverging part of the diffuser were investigated for a range of diverging part lengths. A short diverging part may lead to abrupt pressure recovery, resulting in the possible application of mechanical load to the diffuser.
