Purpose : The purpose of this study was to identify the effect of clinical nurse's locus of control of personality on job stress and job satisfaction and organizational commitment out of organizational effectiveness. Methods : The subjects were 463 staff nurses, who were employed in four university hospitals located in Seoul, Pusan and Kyungki-do. Data was collected from October 4th to October 14th in 2000 by a self-report questionnaire. Data was analyzed by the SAS for the general characteristics of the subjects, descriptive statistics, test for reliability and correlations. The effect of variables were tested using the Lisrel 8.12(a) program. Results : With the findings from this study, the internal-external locus of control affects job stress directly. Also it affects job satisfaction directly and via job stress indirectly. But it affects organizational commitment only via job stress and job satisfaction indirectly. Direct effect of locus of control to organizational commitment is not significant. Job stress affects job satisfaction and organizational commitment out of organizational effectiveness directly. Finally, job satisfaction was direct predictor of organizational commitment. Conclusion : Therefore, nursing managers ought to develop social learning programs to change the perception of individual personality and job stress management programs in order to improve organizational effectiveness.

The purpose of this study was to investigate the factors influencing health perception in the elderly, to provide the basic data for health behavior program and nursing intervention. The subjects of this study were 240 elderly person over the age 60, living in Seoul and Kangnung. They were conveniently sampled for this study and the data was collected from June 1999 to September 1999. The instruments for this study were the Health Perception Questionaire developed by Ware(1979), the OARS Functional Assessment Questionaire (Duke University 1978), and Multidimensional Health Locus of Control by Wallston, Wallston, and De Vills(1978). The data were analyzed by using SPSS Win computer Program. The results are as follows; 1. The total mean score of the health perception was 52.02(S.D=${\pm}$7.07) in a range of 33 to 69, and the mean score of the functional status was 27.02 (SD=${\pm}$2.75) in a range of zero to 28 and the mean score of the health locus of control was 65.66(S.D=${\pm}$8.68) in a range of 43 to 90. And The mean scores on the HLOC subscales were HLOC-I: 23.73${\pm}$4.56 (range: 6-30), HLOC-P: 23.07${\pm}$4.74 (range: 6-30), HLOC-C: 18.55${\pm}$4.03 (range: 11-30). 2. There was a significant positive correlation between health perception and functional status(r=.216, p=.001), and health perception and the health locus of control(HLOC) were not correlated at the level of statistical significance. However, the HLOC-I and health perception were correlated positively(r=.328, p=.000), and the HLOC-P were correlated negatively (r=-.129, p=.046). 3. There was a significant difference statistically in the degree of health perception according to the age(F=3.351, p=.002), spouse(t=2.232, p=.021), education level(F=7.373, p=.001), disease(t=3.639, p=.000), group activity (t=2.458, p=.015). drink(t=2.327, p=.021). 4. Stepwise multiple regression analysis revealed that the most powerful predictor of health perception was internal health locus of control. A combination of HOLC-I, functional status, HLOC-P, group activity explained 17.9% of the variance for health perception in the elderly. In conclusion, the results of this study show that internal health locus of control factor is very important in explaining the health perception for the elderly. Therefore, it will be considered internal health locus of control factor in nursing intervention and program in order to enforce the health behavior for elderly people .

To investigate the influence of the prolactin receptor 3 (PRLR3) gene and the retinol-binding protein 4 (RBP4) gene on the production traits of swine, genotyping was performed on 156 and 141 Berkshire pigs, respectively, that were carefully selected for economic traits. The frequencies of allele A in the PRLR3 locus and allele B in the RBP4 locus were 0.50 and 0.42, respectively. Neither locus was in the Hardy-Weinberg equilibrium. After a genotype was assigned to the individuals whose parents had the homozygous genotype, a statistical analysis was conducted for 291 pigs. The animals with the PRLR3 and RBP4 genotypes included 182 and 227 head, respectively. Even though the genotypic effects of PRLR3 (p<0.05) and RBP4 (p<0.01) had a significant influence on the pigs' back fat thickness, the interaction of both genes was not highly significant in terms of the back fat thickness (p = 0.1235). While the estimated epistasis effects of aaBB and aaBb decreased the back fat thickness and reduced the growth rate, the effects of AAbb and aabb increased the growth rate. Despite the insignificant difference in the PRLR genotypes in terms of the days to 90 kg and the average daily gain, the back fat thickness showed a significant difference (p<0.05), and the additive effect of allele A and the dominant effect of the hetero-genotype were -0.377 and 1.206 mm, respectively. The RBP4 genotypes had a very significant effect (p<0.01) on the back fat thickness, the days to 90 kg, and the average daily gain. The additive effects of allele B of the RBP4 locus on the back fat thickness, the days to 90 kg, and the average daily gain were 0.70 mm, -1.3 days and 6.2 g, respectively. Moreover, the dominant effects of the heterozygote for those traits were 0.63 mm, 9.9 days and -45.0 g, respectively. Allele A of the PRLR3 locus favorably influenced the back fat thickness, the days to 90 kg of the body weight, and the average daily gain and its dominant effect unfavorably influenced those traits. Allele B of RBP4 showed an incremental growth rate and back fat thickness, which could lower the lean meat percentage in the carcass. The RBP4 hetero-genotype negatively affected the pork production. These results strongly imply that the selection of allele A of PRLR3 and allele B of RBP4 would produce highly productive pigs in the Berkshire breed. Careful selection of allele B of RBP4 is required because of the increase in the back fat thickness.

The purpose of this study is to explore the relationships between hope, health locus of control and general health of nursing students. The subjects of this study were 161 female students of National Nursing School in Seoul. Data was collected through a questionnaire from May 11 to May 23, 1998. The tools used for this study were Hope scale developed by Miller and Power, Multidimensional Health Locus of Control Scale developed by Wallston and Wallston and General Health Scale(Modified Conel Medical Index) developed by Nam Ho Chang. Data were analysed in an the $SPSS/pc^+$ program using frequency for the demographic characteristics, 1-test and ANOVA for relationship between the variables and demographic characteristics and for it's differences of hope and general health control. Peason correlation coefficient for relationship between the 3 variables, hope, health locus of control, and general health. The results of this study were as follows ; The 1st hypothesis : that 'Between hope, health locus of control (HLC) and general health of nursing students will have positive relationship', was supported(=.2883, p=.000). The 2nd hypothesis; that 'The hope score of nursing students in HLC-internal group will be higher than others' was supported(F=5.22, p=.0063). The 3rd hypothesis ; that 'The general health of nursing students in HLC -internal group will be higher than others' was accepted(F=2.94, p=.0554). The 4th hypothesis ; that 'Hope, HLC and general health of nursing students according to demographic characteristics will be different ' was accepted in part. o In hope the more age, the higher score. o In HLC the group of non religious have higher score(t=-2.02, p=.045). o No experienced addmission was revealed HLC-internal group(t=-1.91, p=.058). o Non religious group has a tendency to dependent upon on powerful other person(t=-1.99, p=.049). o The hope score of nursing students was very high(4.49/6point). o The general health status of nursing students was vert good(92.88/114point). o Most of nursing students was in HLC-internal group(81.4%). o The most frequent complaints of nursing students was dizziness suddenly developed(68.4/114point), very nervous in small thing(67.83/114) and very nervous to others critics(68.4/114) in turn. In conclusion, the students who have high score of hope, in HLC-internal group have good general health. Hope inspiring not only makes one's good health but also makes others good health and powering hope. For good health person who are in HLC-internal group have powerful hope, keeping good health would be a good stretegy to change the student's HLC and make them good health and hope powering then it would be a good method to change the HLC to HLC-internal group.

This study was designed to explore the effectiveness of education to improve self-care of stroke patients with three types of charactor health locus of control and constitution. A total of 56 patients were selected by convenience sampling at one oriental hospital. The teaching of self-care was conducted by the researcher. The self-care performance was measured for 10 days. The data were analyzed using t-test, ANOVA and Scheffe method as post hoc test. The results of this study are as follows : 1. The self-care performance by patients' characteristics : Age and education had impact on the self-care performance. The level of self-care performance of young and high educated patients was high, gender, religion, occupation, monthly income, and the paralyzed side, however, didn't have influence on the self-care performance. 2. The self-care performance of patients with three types of constitution : There was no statistical significance on the self-care performance of patients group by constitution. However, average score of self-care performance of patients with So-Um was high. 3. The self-care performance of patients with three types of health locus of control : There was no statistical significance on self-care performance of patient group by health locus of control. 4. The correlation between the constitution and the health locus of control : There was no statistical significance on the introverted and chance health locus of control of patients with three types of constitution. However, there was a statistically significant relationship between the powerful others health locus of control and So-Yang. Even though there was no statistically significant self-care performance of patients with So-Um, there was a clinical significance on the high score of self-care performance of patients with So-Um as compared with the self-care performance of the patients. The health locus of control didn't have influence on the self-care performance of patients. There was a statistically significant relationship between the powerful others health locus of control and So-Yang. Therefore, this study suggest the need to develop the nursing intervention to improve the self-care of stroke patients with the powerful others health locus of control and So-Yang, Furthermore, the longitudinal research is needed to determine the effectiveness of training to imp

Data on 63 patients who had had motorcycle accidents and who were admitted to four general hospitals in the Chung Chung Nam Do area from July / 1993 to August 1993 were analyzed. The tool used for this study was a structured questionnaire which consisted of ten items on self- esteem, 18 items on health locus of control and 37 items profiling health prometion lifestyle. Injury severity scores were calculated bated based on data from the patients’ medical records. The collected data were analyzed using the SPSS, yielding descriptive statistics, t-test, ANOVA, Pearson’s Product Moment Correlation. The findings of this study are as follows. 1) Of the 63 injured motorcyclists, 35(55.6%) were helmeted and 28(44.4%) were nonhelmeted, and the nonhelmeted motorcyclists were predominantly young and male. The demographic variables for the helmeted and nonhelmeted groups were heterogeneous for age and occupation. 2) The results of the comparison between the two groups showed a statistically significant difference in the injury severity score(t=-4.70, p=0.000). The helmeted group had lower scores on injury severity score (9.00±3.93) than the nonhelmeted group(14.32土5.05). More than 60% of the nonhelmeted motorcyclists had brain injuries compared to only a third of the helmeted cyclists. 3) There .was a statistically significant difference between the two groups on self esteem(t=4.5, 000). The helmeted group had a higher mean score (31.27±2.72) than the nonhelmeted group(27.46±3.80). 4) The means for Internal health locus of control (IHLC), Powerful others health locus of control (PHLC), and Chance health locus of control (CHLC) in the two groups were similar to instrument norms reported in other literature. The mean scores on the IHLC in the two groups were higher than scores on the PHLC or the CHLC. However, there was a significant difference between the mean scores for the two groups on the PHLC (t=2.85, P=0.006). 5) The mean score for the helmeted group on the health promotion lifestyle profile was higher than the mean score for the nonhelmeted group(107.30±11.10, 96.57土 15.54 respectively), and there was a significant difference between the mean scores (t=3.64, p=0.001) . The highest score for helmeted group on the health promotion lifestyle profile was in the health care domain. However, for the nonhelmeted group the highest score was in the exercise domain and the lowest score was in the health care domain. 6) With regard to the relationship between health promotion lifestyle, health locus of control and self esteem in the two groups, the correlation coefficient between health promotion lifestyle and internal health locus of control for the helmeted group was 50(p〈0.01). For the nonhelmeted group, there was no correlation between health promotion lifestyle and internal health locus of control. However, there were significant correlation between health pro-motion lifestyle and external locus of control(r=0. 46, p〈0.01), and self esteem(r=0.495, p〈0.01). 7) Among the demographic variables, age and education had an impact on individual’s self-esteem The modifying factors of age made a contribution to explaining health - promoting lifestyle. In the present study, more than 40% rf the motorcyclists were riding without a helmet. The incidence of brain injury for patients riding without a helmet was nearly twice as high in the nonhelmeted rider as compared to the helmeted rider. The nonhelmeted motorcyclists in this study had lower self-esteem, obtained a higher score on the IHLC, and were not strongly engaged in performing health promotion activities as compared to the helmeted riders. However, some of the nonhelmeted riders who had a strong belief in PHLC were positively associated with engaging in health promotion activities. Based on the results obtained from this study, strategies to promote helmet usage for motorcyclists have to be developed.

Allelic frequency and genotype distribution of short tandem repeat(STR) F13A01 locus was analysed by polymerase chain reaction, polyacrylamide gel electrophoresis and silver staining from human genomic deoxyribonucleic acid(DNA) was extracted from 205 unrelated Korean to be applied to forensic identification and parentage testing as a database. The results were as follows : 1. 5 alleles and 11 genotypes of F13A01 locus were detected and heterozygosity value was 62.0% and the observed each alleles and allelic frequency was 3.2(0.363), 4(0.105), 5(0.063), 6(0.466), 16(0.002). 2. The allelic diversity value was 0.639 and the power of discrimination was 0.804.3. Compared with observed number of alleles and allele frequency in ethnic difference, result was appeared to be similar to that of Japanese and Asians, while was appeared to be much different to that of Blacks and Caucasians in the observed number of alleles and frequency of allele 3.2, 5, 7. From the above result of this investigation, the allelic frequency of STR F13A01 locus in the Korean was considerd to be useful for individual identification and parentage testing as a database.
