Purpose: The aim of this study was to research caregiver trainees, and to understand the degree of subjective quality of life and internal and external locus control, and to examine the relationships between these variables. Method: The subjects of the research were 348 trainees at a Jeonju city caregiver training center. The subjective quality of life and the characteristics of locus control were used as measuring tools. The collected data was analyzed by the SAS 9.1 program. Result: The degree of subjective quality of life was significantly different according to the general characteristics of age (F=2.83, p=0.02), marital status (F=3.34, p=0.01), and willingness to work (F=3.94, p=0.05). The degree of internal locus control was significantly different according to the general characteristic of marital status (F=3.0 p=0.01). External locus control was significantly different according to the general characteristics of age (F=9.77, p=0.00), occupation (F=2.91, p=0.01), educational level (F=9.65, p=0.00), monthly income (F=3.81, p=0.00), educational institution (F=2.06, p=0.04), educational experience (F=4.15, p=0.00), and subjects willingness to work (t=8.71, p=0.00). A significant correlation was identified between the subjective quality of life and internal locus control (r=0.23, p=0.0001). Conclusion: A significant correlation was shown between subjective quality of life and internal locus control of the caregiver trainees.

This study examined the mediating effect of internal locus of control in the relationship between family and friend support and acculturative stress of North Korean adolescent refugees. Participants consisted of 101 North Korean adolescent refugees (40 males and 61 females) aged 13 to 24, who live in Seoul, Gyeonggi Province, and Busan. SPSS 25.0 and Mplus 5.12 were used to analyze data. Descriptive statistics and Pearson's correlation coefficients were calculated and structural equation modeling (SEM) examined the mediating effect. The results of this study are as follows. First, a higher level of family support and friend support were associated with a higher level of internal locus of control. A higher level of internal locus of control was associated with a lower level of acculturative stress among North Korean adolescent refugees. Second, the level of internal locus of control mediated the relationship between friend support and acculturative stress. This study is meaningful in that it examines the specific paths affecting acculturative stress of North Korean adolescent by examining family and friend support, which are environmental factors, and internal locus of control, which is internal factor of individuals. The study results suggest that improving friend support as well as increasing the level of internal locus of control for North Korean adolescent refugees can be an effective way to prevent or intervene acculturative stress.

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.

Prolactin (PRL) plays an important role in promoting mammalian mammary gland development, and milk production during lactation. Therefore the PRL gene was chosen as a candidate gene for milk traits in Holstein dairy cows. PCR-SSCP and PCR-RFLP were used to analyze genetic variations in the 5' regulation region of the PRL gene. In this part of the gene, two new polymorphic sites were detected in the Chinese Holstein dairy cows. One was a XbaI-RFLP locus, and the other was an SSCP locus. Statistical analysis showed that the XbaI-RFLP locus and the SSCP locus had a significant positive effect on milk traits.

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.

Soybean cyst nematode (Heterodera glycines Ichinohe; SCN) is an important soybean pest and the use of resistant cultivars is the effective method to reduce or eliminate SCN damage. However, breeding for SCN resistance is difficult and expensive by the oligogenic nature of the resistance and genetic variability in the pathogen. Fortunately, SCN resistance loci, rhg1 and Rhg4 are generally accepted as a necessity for the development of resistant genotypes using any source of resistance. In this study, resistance of 44 Korean soybean cultivars to SCN was tested using two molecular markers. Seonheukkong and Pokwangkong were the homozygous to rhg1 locus. Seven cultivars were susceptible to SCN based on Satt309 marker linked rhg1 locus. All Korean cultivars estimated in this study were recessive homozygous to Rhg4 locus and were susceptible in the PCR reaction using primer 548/563 linked to the Rhg4 locus conferring resistance to SCN race 3. Among 44 cultivars estimated, seven cultivars were susceptible to SCN in both Satt309 and primer 548/563 markers. Based on both Satt309 and primer 548/563 markers, there is no resistant cultivar to SCN in Korea. Therefore, SCN resistant cultivars need to be developed in the future. These two markers can be used for improving SCN resistant cultivars.

The DNA profiling of short tandem repeat (STR) markers is a powerful tool for forensic identification and forensic paternity testing. However, STR loci are susceptible to mutation that cause mismatches between parents and children when paternity is tested. Herein, we examined paternity disputes with 23 autosomal STR loci using two commercial human identification kits and revealed successive mismatches at the D13S317 locus across three generations of a Korean family. Additionally, we investigated 12 X-chromosomal STRs and discovered an inconsistency at the DXS10148 locus between the father and daughter of the same Korean family. Furthermore, we confirmed STR genotypes at the D13S317 and DXS10148 loci of the family using sequencing analysis. Consequently, we identified a successive single-step mutation at the D13S317 locus and one single-step mutation at the DXS10148 locus in three generations of the Korean family. Therefore, this case study may be useful for interpreting and understanding forensic paternity tests.

Purpose: To investigate the factors influencing health promoting behavior in college students and to provide a basic data for developing an effective health promotion program. Method: The subjects were 711 college students living in Jecheon city and were selected using a convenience sampling method. The instruments used in this study included the Health Promoting Lifestyle Profile developed by Walker et al.(987). Perceived Health Status developed by Lawston et al. (1982). Self-Esteem scale developed by Rosenberg(1965), Self-Efficacy scale developed by Becker et al. (1993), and Health Locus of Control developed by Wallston et a1.(1978). The data were analyzed by descriptive statistics, pearson correlation coefficient, and stepwise multiple regression using SPSS/WIN program. Results: I) The mean score of health promoting behavior was 2.39 point out of 4. In terms of sub-domains of health promoting behavior, self-actualization(2.78) showed the highest mean score, followed by interpersonal support(2.75), stress management(2.38), nutrition(2.11), exercise(2.04), and health responsibility (1.97). 2) The health promoting behavior had significantly positive correlations with self-efficacy, powerful others health locus of control, internal health locus of control, chance health locus of control, and perceived health status. 3) In the relationship between general characteristics and health promoting behavior, health promoting behavior was significantly different by gender(t=2.17, p=.03), and financial status of parents (F=10.79. p= .00). 4) The most powerful predictor of health promoting behavior was self-efficacy. A combination of self-efficacy, self-esteem, powerful others health locus of control, and sex accounted for 40.4% of the total variance in health promoting behavior. Conclusion: The findings of this study showed that health responsibility and exercise were the domains where the college student showed relatively lower scores than other domains, self-efficacy was the most important predictor of health promoting behavior. Therefore, it is suggested that health promoting programs should focus on health responsibility, and exercise. Nursing strategies that can enhance self-efficacy should also be developed in order to promote healthy lifestyles in college students.
