Objectives : The objectives of this study were to examine the difference in attitude toward health-specific locus-of-control and medical care among western medical students, oriental Medical students, and non-medical school students. Methods : The subjects of this study were 667 students who agreed to respond the questionnaire :212 western medical school students, 190 oriental medical school students, and 205 non-medical school students. The health-specific locus of control was measured by the structured questionnaire developed by Lau and Ware. The attitude toward western and oriental medicine was also measured by the questionnaire. Results : Western medical students and non-medical school students were more likely than oriental medical students to place high value on 'the provider control over health' and 'the general threat to health' scales (F=20.47, F=19.98). But oriental medical school students ranked 'the self control of health' scale as more important than any other locus of control scale (F=19.34). The health specific locus of control was also different from the grade. When trte grade was increased, 'the provider control over health' scale was slowly decreased, especially in western medical students and non medical school students. However, the 'general threat to health' scale was increased in oriental medical students. Western medical school students expressed more positive attitude toward western medicine. Oriental medical school students put a higher score on oriental medicine. Nevertheless, as the grade was increased, the positive attitude toward oriental medicine slightly decreased in oriental medical school students. Conclusions : There is a difference in health-specific locus of control and attitude toward medicine among western medical students, oriental medical students, and non-medical students. The locus of control and attitude of medical students towards medicine may affect both how they behave towards patients and how they help shape future public policy. Therefore, interdisciplinary educational initiatives may be the best way to handle this issue.

The purpose of the present study was to determine whether in vivo noradrenergic neural activity in the locus coeruleus is related to the development of hypertension. Two groups of animals were prepared, 1) young spontaneously hypertensive rats (SHR) and 2) age-matched normotensive wistar kyoto rats (WKY). At il weeks of age, the release of norepinephrine (NE) and 3,4-dihydroxyphenylglycol (DOPEG) from locus coeruleus of young SHR and WKY as an index of neural activity were determined by in vivo microdialysis along with blood pressure (BP) at three conditions : 1) normal; 2) elevated BP by systemic injection of phenylephrine and 3) alpha-1 adrenoceptor stimulated by perfusion of phenylephrine into the locus coeruleus through microdialysis probe. Basal releases of NE and DOPEG from the iocus coeruleus were 0.415+/-0.089pg/20min, 1.311+/-0.293 pg/20min in SHR and 0.204+/-0.078 pg/20min, 1.492+/-0.365 pg/20min in WKY respectively. Basal release of NE from the locus coeruleus of SHR was significantly greater than that of WKY. Phenylephrine systemic injection caused elevation of BP in both SHR and WKY in a dose related manner. Following phenyephrine injection, the releases of NE and DOPEG from the locus coeruleus of SHR were significantly decreased, whereas there were no significant changes in the releases of NE and DOPEG In young WKY. Alpha-1 adrenoceptor stimulation in the locus coeruleus by perfused phenylephrine through microdialysis probe caused pressor responses in both SHR and WKY, but the magnitude of pressor response in SHR was larger compared with that in WKY. The result from the present study suggests that noradrenergic neural activity in locus coeruleus may contribute as one of triggering factors for the expression of hypertension in young SHR.

Leaflet number of soybean controlled by Lf2 locus is the important trait in photosynthesis and plant type. The objective of this research was to identity molecular markers linked to the lf2 locus. A total of $115F_2$ plants were derived from a cross between normal three-leaflet type Sinpaldalkong (Lf2Lf2) and seven-leaflet mutant type T255 (lf2lf2). All leaflet counts of parents and $F_2$ individual plants were made in the field on fully expanded leaves on the main stem when terminal growth of the main stem had ceased. One-thousand 10-mer oligonucleotide RAPD primers and 664 SSR primers were used. The segregation ratios of 3 : 1 were observed in the $F_2$ population and the Chi-square values strongly suggested that the seven-leaflet was controlled by a single recessive gene. A genetic map was constructed from the 15 segregating markers (9 RAPDs, 5 SSRs, 1 lf2 locus). OPAD03 and OPAI13 RAPD markers were linked to the lf2 locus that controlled seven-leaflet type at a distance of 20.5 and 23.5 cM, respectively. Molecular markers identified in this study linked with lf2 locus will be helpful to locate lf2 locus on the public soybean molecular linkage map and would be useful for tagging the lf2 locus that controls seven-leaflet trait.

Two molecular epidemiologic methods, IS6110 restriction fragment length polymorphism (IS6110-RFLP) and 24-locus mycobacterial interspersed repetitive unit-variable-number tandem repeat (MIRU-VNTR), are used worldwide in studies of Mycobacterium tuberculosis (MTB). Conversely, because of its poor resolution, pulsed-field gel electrophoresis (PFGE) is not widely used for MTB. In this study, we improved the 24-locus MIRU-VNTR and PFGE protocols and compared the effectiveness of these approaches for the molecular typing of MTB using 75 clinical isolates obtained from a cohort investigation of high-risk populations infected with MTB. The 24-locus MIRU-VNTR method demonstrated superior discriminatory ability, followed by PFGE and IS6110-RFLP. Next, we analyzed six isolates with clear epidemiologic connections; that is, isolates from patients who attended the same school. IS6110-RFLP and PFGE identified these samples as the same type. By contrast, according to MIRU-VNTR, two isolates differed from four other isolates at one locus each; one isolate was identified as Mtub29 and the other as QUB-26. In summary, the 24-locus MIRU-VNTR assay was the most useful molecular typing method among the three methods investigated due to its discriminatory power, short time required, and availability as an epidemiologic investigation tool. PFGE was the second-best method. Compared with the other loci assessed in the 24-locus MIRU-VNTR assay, the Mtub29 and QUB-26 loci appeared to exhibit greater variability during transmission.

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.

The purpose of this study were l) to provide information useful in developing an individualized health promotion program, 2) to test the correlations among the level of locus of control, health promotion activities and value placed on self. 3) to assess the factors of health promotion activities and value placed on self. The level of locus of control was measured by Walston/Walston's scales. The levels of health promotion activities and value placed on self were measured by Pender/Pender's scales. The sample consist of 122 female students in a University in Seoul. Their mean ages were 21. The results are summarized as follows; 1. Hypothesis 1 : The higher the score of internal health locus of control, the higher the score of health promotion activities was supported. 2. Hypothesis 2 : The higher the score of value placed on self, the higher the score of health promotion activites was supported. 3. Hypothesis 3 : The higher the score of value placed on self, the higher the score of internal health locus of control was supported. 4. The highest score of the factors of health promotion activities is nutritional practice$(14.976\pm.907)$ and the lowest score is self care$(1l.930\pm1.169).$ In conclusion, several implications for nursing emerge from the theory and research behind the locus of control concept. First, scales to measure locus of control may be useful in evaluating health education programs. Second, it may be adventageous to screen individuals using a health locus of control scale before placement into a treatment program that matches their needs. Third, health professionals may want to train individuals to become more internals appear more likely to engage in positive health behaviors.

Purpose: The aim of this study was to identify the status of performance on standard precautions among nursing students and to examine the mediating effects of internal health locus of control on the relationship between awareness and performance on standard precautions of hospital-acquired infection control. Methods: The participants in this study were 134 nursing students. The measurements included a standard precautions awareness and performance scale, and a multidimensional health locus of control scale. Data were analyzed using independent t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient, and simple and multiple regression techniques. Mediation analysis was performed by the Baron and Kenny's method and Sobel test. Results: The mean score of standard awareness, standard performance, and internal health locus of control about standard precaution were $174.30{\pm}9.08$; $169.48{\pm}12.04$; and $20.43{\pm}2.82$; respectively. There was a positive correlation between standard awareness and performance (r=.414, p<.001). Also, standard awareness was significantly correlated with internal health locus of control (r=.413, p=.014). Internal health locus of control showed partial mediating effects in the relationship between awareness and performance. Conclusion: The results indicate a need to improve the internal health locus of control of nursing students. Therefore, an internal health locus of control improvement program should improve performance on standard precautions for patients and themselves.
