The aim of this study is to describe degree of fatigue and factors related to fatigue in patients with rheumatoid arthritis. The subjects of the study consist of one hundred fifty-eight outpatients with rheumatoid arthritis at three university hospitals in Taegu between July 10 and August 30, 1999. The instrument used in this study was the Multidimensional Assessment of Fatigue developed by Belza et al.(1995) and revised by Jung, Bok Hee. Kim, Myung Ae(1998). Analysis of data was done by using the descriptive statistics, t-test, ANOVA and Duncan with SPSS program. The major findings can be summarized as follows: 1. Degree of fatigue in patient with Rheumatoid Arthritis was shown the average 22.91 out of the total scores 40. Four subscales of fatigue scores are common fatigue degree 6.37, fatigue timing at the last week 5.92, distress due to fatigue 5.40 and degree of daily activity fatigue 5.22. Among the realms of daily activity fatigue, outdoor activity(6.00), sexual life(5.84), doing the household(5.66), shopping(5.61), other exercise except stroll(5.54) were shown the high degree of fatigue and cooking(4.97), a stroll(4.48), recreation(4.35) showed the low degree of fatigue. 2. There were no significant differences on the total degree of fatigue according to demographic variables. But there were some significant differences on the subscale fatigue scores according to demographic variables. Degree of daily activity fatigue according to sex was shown significant difference (t=-2.358, p=.020), and according to education level was shown significant difference(F=3.938, p=.005) and common fatigue degree according to age was shown significant difference(F=2.853, p=.026). Conclusively fatigue is one of difficult problems for patients with rheumatoid arthritis. Therefore it is necessary to develop some nursing intervention for reducing fatigue of rheumatoid arthritis patients.

Purpose : This study was undertaken to evaluate the effects of the different administration duration of Ginseng Radix Alba extract solution on the spermatogenic abilities. Methods : We used the 2-month-old mice and administered Ginseng Radix Alba extract solution 0.3mg/g/day for 30, 60, 90 and 120 days. The control group was administered the normal saline in the same way. We examined the number of total, motile and normal sperm from the cauda epididymis, the activities of sperm hyaluronidase. Also we observed changes of isolated testis before and after administration of Ginseng Radix Alba extract solutions in the mice. And we compared to the testicular tissue especially seminiferous tubules between control and treated group by histochemical methods. Results : The significant differences were observed in the concentration of total sperm and normality of spermatozoa of the Ginseng Radix Alba extract solution administered groups compared to the control group in 60, 90 and 120days groups. The significant differences were observed the motility of the Ginseng Radix Alba extract solution administered groups compared to the control group in 90 days group respectively. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Ginseng Radix Alba extract solution administered groups compared to the control group, respectively. but the activity of hyaluronidase was not significantly increased in the Ginseng Radix Alba extract solution administered groups Conclusion : This study shows that Ginseng Radix Alba has the beneficial effect on the concentration, morphology and motility of sperm especially in 90 days administration group. We can suggest that Ginseng Radix Alba extract solution be useful for the treatment of male sexual dysfunctions and infertility.

Objective: The aims of this study were to investigate a simple method for assessing anterior-posterior jaw relationships via cone-beam computed tomography (CBCT) images taken in the natural head position (NHP) relative to the nasion true vertical plane (NTVP), and measure normative data in Korean adults with normal profiles. Methods: Subjects were selected from patients presenting for third molar extraction and evaluated as having normal profiles by three examiners. The CBCT images of 80 subjects (39 males, 41 females) were taken in the NHP according to Solow and Tallgren's method. Linear measurements of the A-point, B-point, and Pog were calculated relative to the NTVP. Student's t -test was used to assess sexual differences in these measurements. Results: The mean linear measurements of the A-point, B-point, and Pog relative to the NTVP were 0.18 mm (standard deviation [SD], 4.77 mm), -4.00 mm (SD, 6.62 mm), and -2.49 mm (SD, 7.14 mm) respectively in Korean males, and 1.48 mm (SD, 4.21 mm), -4.07 mm (SD, 6.70 mm) and -2.91 mm (SD, 7.25 mm) in Korean females respectively. There were no statistically significant differences between Korean males and females (p < 0.05). Conclusions: Three-dimensional CBCT analysis using the NTVP is a simple and reliable method for assessing anterior-posterior skeletal relationships.

A total of 352 specimens of congeneric species of Agkistrodon was collected and morphometric analysis and starch-gel electrophoresis were carried out in order to investigate the taxonomic status of this genus. The results obtained in this study are as follows: Morphometric analysis 1. Three species are recognized based on Gloyd's criteria. There was no specimen that was doubtful to classify correctly. Therefore, it seems that Gloyd's morphological characters are good criteria to identify each species. 2. All three species are sympatric at two localities (Mt. Seolag, Gangwon-do, and Mt. Deogyu, Jeonra-bugdo) and A. caligino년 and A. b. brevicaudus are sympatric at Gwangneung and Mt. Yongmun, Gyonggi-do. No hybrids were found in these sympatric localities. 3. Notable sexual dimorphism was found in meristic characters. 4. A. saxatilis has signicantly more number of ventrals and shorter tail ratio than other two species. 5. There were no significant meristic character differences between A. caligino년 and A. b. brevicaudus. Genetic analysis 1. Among 26 loci investigated, 12 loci (46.1%) were identical in their mobility, 4 loci (15.4%) were nearly identical with minor frequency differences, and 10 loci (38.5%) showed interspecific mobility difference. 2. The average proportion of polymorphic loci was 9.03%. This is considerably less than that of other vertebrates. 3. The average S and D values between species are .695 and .342 respectively. These values indicate that three taxa are distinct species. 4. A. caliginosus is genetically more related to A. saxatilis than to Agkistrodon, namely A. b. brevicaudus, A. caligino년 and A. saxatilis, as proposed by Gloyd. Far from being mere morphological variants, as suggested by Kang and Yoon (1975), they are highly distinctive evolutionary units.

Objective: The growth and development of the mandible strongly depend on modeling changes occurring at its ramus. Here, we investigated covariance patterns between the morphology of the ramus and the rest of the face. Methods: Lateral cephalograms of 159 adults (55 males and 104 females) with no history of orthodontic treatment were collected. Geometric morphometrics with sliding semi-landmarks was used. The covariance between the ramus and face was investigated using a two-block partial least squares analysis (PLS). Sexual dimorphism and allometry were also assessed. Results: Differences in the divergence of the face and anteroposterior relationship of the jaws accounted for 24.1% and 21.6% of shape variation in the sample, respectively. Shape variation was greater in the sagittal plane for males than for females (30.7% vs. 17.4%), whereas variation in the vertical plane was similar for both sexes (23.7% for males and 25.4% for females). Size-related allometric differences between the sexes accounted for the shape variation to a maximum of 6% regarding the face. Regarding the covariation between the shapes of the ramus and the rest of the face, wider and shorter rami were associated with a decreased lower anterior facial height as well as a prognathic mandible and maxilla (PLS 1, 45.5% of the covariance). Additionally, a more posteriorly inclined ramus in the lower region was correlated with a Class II pattern and flat mandibular plane. Conclusions: The width, height, and inclination of the ramus were correlated with facial shape changes in the vertical and sagittal planes.

Three species, Gymnogobius urotaenia, G. sp. 1 and G. sp. 2, collected at Hosan-river, Hosan-ri, Samcheock-si, Gangwon-do, Korea, were examined for the study of sexual dimorphism. The three species have peculiar nuptial pigmentation during the breeding season: all females of the three species showed an intense black coloration on the ventral part of the head, the pelvic fin, the anal fin and the margin of the first dorsal fin. There was a difference between G. sp. 1 and the other two species in 1/3 from margin of first dorsal fin. Namely, G. sp. 1 showed an intense black coloration, whereas the other two species had an intense yellow coloration. All females of the three species showed the same, intensely yellow coloration in the ventral part of the body. Males of G. urotaenia and G. sp. 2 had almost the same nuptial pigmentation, however the former showed diffuse black coloration in the anal fin, whereas the latter had an intensely black anal fin. Males of G. sp. 1 differed from those of the other two species in their yellow color on the ventral part of the head, the pelvic f ins, the anal fin, in contrast to the diffuse black coloration in those parts in the other species. The genital papilla of males was triangle-shaped, but that of females was heart-shaped. Significant differences between sexes include: G. urotaenia, 7 characters (body depth, head length, snout length, upper jaw length, head depth, pectoral fin ray length, eye diameter); G. sp. 1, 11 characters (body depth, head length, caudal peduncle length, caudal peduncle depth, snout length, upper jaw length, head width, head depth, anal fin ray length, pectoral fin ray length and caudal fin ray length); G. sp. 2, 10 characters (body depth, head length, caudal peduncle depth, snout length, upper jaw length, head width, anal fin ray length, pectoral f in ray length, caudal fin ray length and eye diameter). Of the 5 characters which showed differences in all three species (body depth, head length, snout length, upper jaw length and pectoral fin ray length), females had higher values than males only in body depth, whereas males values in all other characters. The upper jaw length was the most distinctive sexually dimorphic feature, the upper jaw extended beyond the posterior margin of the eyes (p<0.001) in males but not in females.

The purpose of this study were 1) to identify the differences between homosexual and heterosexual men in clothing behaviors(fashion leadership, preference for up-to-date style and sexual attractiveness), lifestyle and sex-role attitudes, and 2) to investigate the relation- ships between clothing behaviors and lifestyle and sex-role attitudes. The data was collected via self-administered questionnaires from 183 adult men(88 homosexual, 95 heterosexual men) living in Seoul, and was analyzed by factor analysis, t-test, correlations and multiple regressions. The result of this study were as follows: 1. Two factors of fashion leadership. were identified: fashion opinion leadership and fashion innovativeness. Four factors of lifestyle were identified: appearance awareness, self-confidence, authoritativeness, and achievement. 2. The result of t-test between homosexual and heterosexual men in clothing behaviors and psychological characteristics, homosexual men showed higher scores in fashion innovativeness, fashion opinion leadership, preference for up-to-date style, and appearance awareness of lifestyle characteristics. 3. From the result of analyzing the effects of psychological characteristics on 4 variables of clothing behaviors, appearance awareness of lifestyle characteristics was found to be the most influential factor for all the clothing behavior variables in both groups.

The purposes of this study were to identify the relationship between children's personality traits and self-esteem, and to find out if there were any differences in the relationship patterns in terms of children's sex. The questionnaire were collected from 984 subjects in 5th grade of elementary schools located in cities of Seoul, Suwon, Daejeon, and Daegu. Results showed that personality factors such as stability, sociability, responsibility, and superiority had stronger correlations with self-esteem factors whereas masculinity, activity level, and reflectivity did so to a less degree. Children's personality factors such as superiority, sociability and responsibility were better predictors of their self-esteem factors such as scholastic competence, social acceptance and general self-worth. Girls showed higher level of stability, sociability, responsibility and superiority, however there was no sex difference in the self-esteem such as scholastic competence, social acceptance and general self-worth. Children's behavioral conduct were mainly explained by masculinity, activity level, and responsibility. Responsibility turned out to be the strongest predictor of behavioral conduct among boys, while the activity level did among girls.

The purpose of this study was to examine health promotion level and related of patients hospitalized. The participants for this study 225 of oriental medicine hospital inpatients. Health promotion, sleep, anxiety and discomfort are measured structured questionnaires each. Data were collected using structured questionnaires and analyzed using t-test, ANOVA and multiple regression. The general health promotion score is 98.12, mortality health promotion 20.31, mental health promotion 12.89, dietary health promotion 15.28, activity and rest health promotion 12.84, exercise health promotion 7.23, sleepy health promotion 15.42, seasonal health promotion 7.60 and sexual health promotion 9.31. There were significant differences in health promotion level according to spouse (p=0.003), sleep (p<0.001), anxiety (p<0.001) and discomfort (p<0.001). The significant predictors of health promotion were spouse (p<0.001), religious (p<0.001), drinking (p=0.036), sleep (p<0.001) and discomfort (p<0.001), explaining 33.7% of the variance in health promotion. Health promotion influenced not only the physical condition but also the psychological condition. The result suggest the health promotion level and predictors of health promotion is a useful index for improvement of health and prevention of disease in oriental medicine.
