The purpose of the present study was to address whether the in vivo noradrenergic neural activities in the locus coeruleus are involved in the regulation of blood pressure. Two groups of the animals were prepared, 1) SHR and 2) age-matched normotensive control, WKY. At the age of 6 and 16 weeks, blood pressure and the releases of NE from the locus coeruleus in SHR and KWY were measured by in vivo microdialysis at three different conditions: 1) normal, 2) elevated state of blood pressure by systemic injected phenylephrine and 3) increased state of neural activity by perfused phenylephrine into the locus coeruleus. The basal release of NE of SHR were significantly higher than that of WKY, Phenylephrine treatment caused elevation of blood pressure in both SHR and WKY in dose-dependent manner. Following phenylephrine injection, the releases of NE from the locus coeruleus of SHR were significantly decreased, whereas the significant change of NE in WKY was observed in the highest dose of phenylephrine. Phenylephrine perfusion into the locus coeruleus through microdialysis probe caused pressor responses and the pressor response in SHR was greater compared with that in WKY. The results from the present study suggests that the noradrenergic nervous system in the locus coeruleus may contribute as one of the development and maintenance factors for hypertension in SHR.

The purpose of this study was to identify relationship between Health Locus of Control and Health Promoting Behavior. The subjects of the study were 333 college women at D University in Seoul. The tools used for this study were Health Locus of Control developed Wallston et al(1978) (by modified Lee, 1994), Health Promoting Behavior Scale developed by Walker et al(1987) were modified by researcher. The descriptive-correlational study were analyzed by descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, Stepwise Multiple Regression using SPSS/PC+ program. The results were as follows : 1. Hypotheses 1 that higher the score of internal health locus of control, the higher the score of the level of health promoting behavior was supported(r=.4951, p<.001). Hypotheses 2 that the higher the score of chance health locus of control, the lower the score of the level of health promoting behavior was supported(r=-.3383, p<.001). 2. By means of multiple regression analysis, health locus of control provided explained 24.5% of health promoting behavior. 3. General Characteristic variables significantly related to the health promoting behavior were a major field of study, experience in learning health education.

This study was designed to examine the relations of home environment, locus of control, social support and behavior problems of fourth-grade Korean-Chinese children in Yanbian in China. The subjects were 190 children who completed the locus of control and social support scale and their parents who completed the Child Behavior Checklist. T-test, correlation analysis, and multiple regression analyses were conducted. Mother's education level, and psychological and physical environment at home were negatively related to children's behavior problems. The scores of internal locus of control and support from the teacher were negatively related to children's behavioral disturbances. The factors with the greatest contribution to explaining behavior problems of Korean-Chinese children in Yanbian were found to be physical environment at home, internal locus of control, and teacher's social support.

Meta-cognition is the knowledge and cognition of cognitive phenomena, including the control of ones own memory, comprehension, and thought processes. Meta-cognition is similar to self-awareness, which is the understanding of oneself, and affects people's attitudes and behaviors. This study demonstrated the mediating effect of meta-cognition between internal locus of control and self-efficacy. Internal locus of control refers to the steady faith that any outcome is related to one's own efforts. Self-efficacy is a collection of personal strong belief that one individual can achieve his or her own goals. In this study, if a person has a tendency to adopt an internal locus of control, meta-cognition is improved, and self-efficacy can in turn be increased if meta-cognition is improved. This study conducted an empirical analysis through questionnaires conducted on 260 university students. The results of the research demonstrated that there is a highly positive correlation between meta-cognition, control position, and self-efficacy. In addition, this study emphasized that positive meta-cognition with internal locus of control can lead to positive attitudes and behaviors, and positive results.

This study aims to document empirically the individual factors that influence the intention to do whistleblowing. This study uses several variables, including internal locus of control, external locus of control, and whistleblowing intention. The use of the theory of Planned Behavior in this study is to explain and analyze the perception of behavior control as a determinant of whistleblowing intention. A quantitative research approach is used. The type of data in this study is primary data in the form of a questionnaire. The data collection method in this research is using the survey method. The sampling technique used a nonprobability sampling method, namely, the census method. The census method is the entire population sampled. The population in this study was all employees of the Pratama tax office in West Semarang. The research was conducted by distributing 111 questionnaires. Ninety-one valid questionnaires were returned appropriate for analysis. The data were processed using Partial Least Square-Structural Equation Modeling ((PLS-SEM) using the Warp PLS 7.0 program. WarpPLS 7.0 was used to test hypotheses and the relationship between variables. The study results showed that both internal locus of control and external locus of control affect whistleblowing intention.

This study was conducted to investigate the relationship between self efficacy and a health locus of control. We conveniently sampled 204 university students who smoke. We invastigated by using questionaries and collected data that were analyzed using a t - test, an analysis of variance, a Pearson product-moment correlation. The results are as follows: 1. The average score of self efficacy was 66.16 (out of a total score of 100.00) in university students who smoke. In relation to the health locus of control, the internality score was highest at 25.22, the influence of others was 20.39, and the effect of chance was 15.86. 2. In a significant test of the general character other and aspect related to the smoking of the subjects and in the score of the health locus of control, the internality score of subjects who had been never been asked to quit smoking was higher than that of subjects who had been. There are significant differences in the scores concerning the influence of powerful others, especially religion. In chance occurrences, the score of subjects in medical school was higher than in other schools. The lower the age one beginns smoking, the higher the score of chance. 3. In a significant test of the general character and other aspects related to smoking and the score of self efficacy, there was no significant relationship. 4. Considering the relation of self efficacy to a health locus of control, a positive relationship between self efficacy and internality, and the influence of others, but not between self efficacy and the effect of chance. With these results, we can conclude that the higher the level of self efficacy, the higher the internality, the higher the influence of powerful others. Consequently, it is necessary to identify the relationships clearly among self efficacy the health locus of control by repeated research. It can be used to support, revise and develop health behavior theory.

The purpose of the study was to test the reliability and validity of the Korean version of Children's Health Locus of Control Scale (CHLC), an instrument designed to measure health locus of control in children aged 7 to 12. The scale was administered to 467 children in grades 4 to 6, enrolled in 2 elementary schools located in city. The mean age of the subject was 10.03 (SD=1.33). The findings were as follows: 1. Cronbach alpha coefficient for internal consistency was .69 for the total, and .67, .65, and .56 on the respective subscales. 2. Construct validity was supported through factorial isolation of three theory consistent subscales : internal, chance, and powerful others. Two items did not fit well with the originally developed subscale. The total percent of varience explained by 3 factors was 34.5%. The result of the factor analysis according to Kaiser's criterion revealed that the scale was consisted of 5 factors. But, The items of the subscales were rather inconsistent with the dimensions of the locus of control concept. 3. There were significant differences according to parent's educational level and occupation, and birth order on the scores of the CHLC. There were no significant differences according to grade level and sex. 4. The score of the CHLC was significantly correlated with the self concept of the children(r=.14, p<.001). The result indicated that the Korean version of Children's Health Locus of Control Scale was valid and reliable in measuring health locus of control concept in children, even though luther research is required to reconfirm and increase the reliability of the instrument. CHLC could be used for study explaining the health related behavior of the children and research project related to health education program.

This descriptive-correlational study was undertaken in order to examine if there was relationship between health locus of control and health behavior of 122 residents in Choong Nam Province. The sampling method was non-probability, conventent sampling technique. Questionnaire survey was conducted from March 2 to March 11, 1988. Each participant completed the Multidimensional Health Locus of control(MHLC) scale (Wallsten & Wallston, 1978) and Health Behavior scale (developed by Dr. cho) The collected data were analyzed using Peason Correlation coefficient, t-test and Analusis of Variance. The results were as follows : 1. Hypothesis 1, stating that the higer the score of internal health locus of control, the higher the Score of level of actual implementation of health behavior was supported(r＝.1344, p＜.05). 2. Hypothesis 2, stating that the higher the score of chance health locus of control, the lower the score of level of actual implementation of health behavior was not supported (r＝-.1344, p＞.05). 3. Hypothesis 3, stating that the higher the score of internal health locus of control, the higher the score of the level of perceived importance of health behavior was supported (r＝.3373, p＜.001). 4. Hypothesis 4, stating that the higher the score of chance health locus of control, the lower the score of level of perceived importance of health behavior was not supported (r＝-.0810, p＞.05). 5. The mean score of internal was 23.36, powerful others was 19.04 and chance 15.36 out of maximum range of 6-30 respectively. The mean score of level of actual implementation of health behavior was 112.84 and level of perceived importance of health behavior 143.60 our of maximum range of 32-160 respectively. 6. The variances which were related with the level of actual implementation of health behavior, were education level, occupation, economic status, referred method of primary health, management and resicent's place. And the variance which were related with the level of perceived importance of health behavior were sex, economic status and occupation.

The purpose of this study was to investigate between locus of control, body cathexis and four aspects of clothing behavior. Locus of control was measured by Rotter's The Internal-External Scale and body cathexis by Secord and Jourard's Body Cathexis Scale. Two aspects of clothing behavior were assessed with Lee's questionnaires dealing with status symbol and clothing satisfaction. Clothing Acceptance I was determined with questionnaires designed to measure the acceptance of color and casual wear and Clothing Acceptance II by line drawings of clothing representing formal type, informal type, and new mode type designed to measure the acceptance of business suits. The questionnaires in this study were administered to a sample of men (between 20 to more than 60 years of age) in Seoul. The data from 303 respondents were analyzed. The results were: 1) Locus of control was not related to Clothing Acceptance I(acceptance of color and casual wear), but positively related to Clothing Acceptance II(acceptance of business suit), that is, the persons having wider latitudes of acceptance in business suits were internally controlled in locus of control. 2) Locus of control was negatively related to status symbol, that is, the persons having higher concepts in status symbol were externally controlled in locus of control. 3) Body cathexis was positively related to clothing satisfaction, that is, the persons having higher satisfaction toward their clothing were more satisfied with their body.

The purpose of the present study was to address whether the in vivo noradrenergic neural activities in the locus coeruleus are related to the development of hypertension. Two groups of the animals were prepared, 1) young SHR and 2) age-matched normotensive control, WKY. At the age of 6 weeks, blood pressure and the releases of NE and DOPEG from the locus coeruleus in young SHR and WKY were measured by in vivo microdialysis at two different conditions; 1) normal and 2) elevated state of blood pressure by systemically injected phenylephrine. Basal releases of NE and OOPEG from the locus coeruleus were $0.415 \pm$0.089 pg/20 min and $1.311 \pm0.293$ pg/20 min in SHR and $0.204\pm0.078$ pg/20 min and $1.472\pm 0.365$ pg/20 min in WKY The basal release of NE of SHR was significantly greater than that of WKY. Phenylephrine treatment caused elevation of blood pressure in both SHR and WKY in dose-dependent manner. Following phenylephrine injection, the releases of NE and DOPEG from the locus coeruleus of SHR were significantly decreased, whereas there was no significant changes of NE in WKY. The results from the present study suggests that the noradrenergic nervous system in the locus coeruleus may contribute as one of the triggering factors for the expression of hypertension in young SHR.
