This study was to investigate whether there are any differences in social competence by the frequency of young children's video and computer game use. Social development was categorized as peer popularity and social competence. The subjects were 215 children(118 boys, 97 girls) aged 4-6 years(M= 63.6 months, SD=6.8) from 3 kindergartens in Chung-Cheong Nam Do. The frequency of children's video and computer game use was reported by their parents. Peer popularity was rated by their classmates and social competence by their teachers with Kohn Social Competence Scale(KSCS). No significant relationship was found between game use and peer popularity. The children who played video and computer games once or twice a week got the highest score on the‘social interest and participation’But social cooperation dimension was not related with the frequency of video and computer game use but with the sex of children.

Purpose: Breast cancer is known to be more vulnerable to bone metastasis and lymph node metastasis than other types of cancer, and nuclear examinations whole body bone scan and lymphoscintigraphy are performed commonly before and after breast cancer operation. In case whole body bone scan is performed on the day before lymphoscintigraphy, the radiopharmaceutical taken into and remaining in the bones provides anatomical information for tracking and locating sentinel lymph nodes. Thus, this study purposed to examine how much bone density affects in locating sentinel lymph nodes. Materials and Methods: The subjects of this study were 22 patients (average age $52{\pm}7.2$) who had whole body bone scan and lymphoscintigraphy over two days in our hospital during the period from January to December, 2009. In the blind test, 22 patients (average age $57{\pm}6.5$) who had lymphoscintigraphy using $^{57}Co$ flood phantom were used as a control group. In quantitative analysis, the relative ratio of the background to sentinel lymph nodes was measured by drawing ROIs on sentinel lymph nodes and the background, and in gross examination, each of a nuclear physician and a radiological technologist with five years' or longer field experience examined images through blind test in a five-point scale. Results: In the results of quantitative analysis, the relative ratio of the background to sentinel lymph nodes was 14.2:1 maximum and 8.5:1 ($SD{\pm}3.48$) on the average on the front, and 14.7:1 maximum and 8.5:1 ($SD{\pm}3.42$) on the average on the side. In the results of gross examination, when $^{57}Co$ flood phantom images were compared with images containing bones, the score was relative high as 3.86 ($SD{\pm}0.35$) point for $^{57}Co$ flood phantom images and 4.09 ($SD{\pm}0.42$) for bone images. Conclusion: When whole body bone scan was performed on the day before lymphoscintigraphy, the ratio of the background to sentinel lymph nodes was over 10:1, so there was no problem in locating lymph nodes. In addition, we expect to reduce examination procedures and improve the quality of images by indicating the location of sentinel lymph nodes using bone images as body contour without the use of a source.

Young black men(YBM) have the most severs levels of high blood pressure(HBP) and, in all reports but one, the lowest of HBP control of any age /sex /race group. To increase entry into care, remaining in care, and BP control for young(18-49 years) Black men, It is needed to review socio-demographic, medical characteristics, and behaviors(importance of and difficulty with HBP control behaviors, or worry about mdication) for experimental intervention study(educational- behavior strategies) of hypertensive urban young black men. The 204 participants had an average age of 38.8+7.0 years and an average educational level of $11.0{\pm}2.4$ years; only 23.1% were employed full- or part-time while 26% were on disability ; and 6% were married. Only 35.3% had an MD for HBP care and 37.3% had some form of health insurance. The average BP of those men currently being in care on medication(35.3%) was $148.2/95.1{\pm}19.5/11.3$ compared to those men not taking HBP care $153.7/99.1{\pm}14.0/9.8(p<.05)$. The average creatinine level was 1.3(excluding 3 marked elevations of 15.9, 9.6, and 7.7) for the 163 men consenting to have their blood drawn. Self-reported co-morbidity induded heart disease 7.8%, diabetes 8.9%, high cholesterol 18.2%, CVA 3.4%, alcohol and drug related problems 27.9% and 22.5% respectively. The kidney disease of those men currently being in care & on medication was 9.7 compared to those men not taking HBP care 0.8(p<.05). The problems of with sex life, physicl activity and dearly thinking of those men currently being in care & on medication was higher compared to those men not taking HBP care(p<.05). Questions of 'during the past month, on how many days did you have 5 or more drinks (bottles) of any alcoholic beverag?' and smoking of those men currently being in care & on medication was 18.1% and 72.2% compared to those men not taking HBP care 27.3 and 82.6%, respectively. HBP control behaviors was assessed with 1-5 point Likert subscales(5=extreme, 1-none at all), In general, th men reportd low levels of perceived psychological barrier to HBP care and control behaviors; importance of and difficulty with HBP control behaviors, or worry about mdication. For example, on a five point scale(1=none at all, 5=extreme), average ratings for perceived important and difficulty with BP care and behaviors were 2.8(SD=1.2) and 2.5(SD=1.1). Average ratings for perceived benefit with BP care and behaviors worry about medication of those men currently being in care on medication was 4.0(SD=0.9) and 2.2(SD=1.1) compared to those men not taking HBP care 3.6(SD=0.8), 2.8 (SD=1.6) respectively(p<.05). These data support the need for educational-behavioral strategies of community health nurse to improve high blood pressure control in this high risk group through perceived barriers to treatment, health care skills and use of resources, and social support.

The purpose of this study is to provide the basic data for developing a social policy program and group counseling program that will help matriarchs adapt successfully by investigating the level of depression and perceived health status in them. The data was collected from the period February to July, 2000 which included 155 matriarchs who registered at the 'YWCA', 'Working Women Center' located in Busan. The matriarche's depression was measured through a questionnaire composed of 13 selected items which correspond to depression of SCL-90-R scale and the tool for perceived health status measured by Ware(1976) translated by Yoo Ji Soo, Kim Jo Ja and Park Ji Won (1985). The data was then analyzed using descriptive statistics, t-test, ANOVA and pearson correlation coefficient. The result of which are, as follow: 1. The mean score of depression was 30.8 (SD=${\pm}5.1$) from a range of 13 to 52, and perceived health states was 28.3 (SD=${\pm}4.4$) from a range of 11 to 44. 2.83.3% of the matriarchs have experienced mild depression and above and 3.9% of them experienced high level of depression. 9.0% of the matriarchs perceived their health status low and 78.6% of them have percieved their health status moderately. 3. There was a significant difference statistically in the degree of depression according to the religion(t=2.852, p=.005) and income(t=4.25, p=.000). 4.There was also a negative correlation between depression and perceived health status (r=-.499, p=.000) In conclusion, the majority of matriarchs have experienced depression and perceived their health status below moderately, and there was a significant correlation between depression and preceived health status. Considering these facts therefore, We recommend that this data be used in developing nursing intervention program and in understanding matriarchs. Finally, it is suggested that the nursing assistance for matriarchs should not be limited only to physical support but also psychological and systematic support as well.

An experimental study was performed to evaluate the seismic performance of beam-column connections using 600 MPa re-bars for beam flexural reinforcement. Three full scale specimens of interior beam-column connection and two specimens of exterior beam-column connection were tested under cyclic loading. The specimens were designed to satisfy the requirements of Special Moment Frame according to current design code. The structural performance of the specimens with 600 MPa re-bar were compared with that of the specimen with 400 MPa re-bars. The test results showed that bond-slip increased in the beam-column joint. However, the load-carrying capacity, deformation capacity, and energy dissipation capacity of the specimens with 600 MPa re-bar were comparable to those of the specimens with 400 MPa re-bars.

This study analyzed faculties' perceptions on the importance and performance of effective teaching behaviors. The effective teaching behaviors scale consisted of 40 items belonging to 8 factors. A survey was conducted with 86 faculties from 2 universities. It was found that the differences between the importance and performance levels of all items except for 'applying emphasis on important contents' were statistically significant. The scores of importance were higher than those of performance. The results of the IPA showed that 'keep up the good work' area included 19 items that those were high the scores of importance and performance. The 'concentrate here' area included 5 items that need to be improved for effective teaching. The first priority items needing to be improved were 1) Establishing instructional methods and strategies suitable for the objectives, 2) establishing clear objectives, appropriate examples and systematic classes, 3) providing questions, opportunities and appropriate feedback. We suggested that a faculty development program needs to be developed for effective teaching.

The purpose of this study was to survey the general characteristics, lifestyle include health habits, subjective health problems include physical, psychological and overall health complaints that occurring among Korean and Japanese nursing students. Data collected with the self-administered Okayama Medical Index Health Questionnaire(devised Cornell Medical Index) from 466 Korean and 688 Japanese Nursing Students were analyzed. The subjects were 18 to 24 years old in their 1st, 2nd, 3rd and 4th year-class of nursing department. The total O.M.I. score(section A-R) ranged from 1 to 110 with an average of 22.3(SD=11.5) in Korean nursing students and 18.3(SD=10.1) in Japanese nursing students. A statistically significant inverse correlation was observed between Korean nursing student and Japanese nursing students for the overall health complaints. Korean nursing students have more health problems than Japanese nursing students in terms of physical and overall health complaints excluding psychological problems. About $4\%$ of Korean nursing students were current smokers and $64.2\%$ of Korean nursing students were drinker. Korean nursing students in the drinker's group were more likely to eat fatty foods(p<.001), and take worst lifestyle and have more subjective health problems than non drinker's group of Korean nursing students. Korean nursing students were more likely to perform bad health behaviors than Japanese nursing students. The drink habit is one of the biggest problems among the nursing student, and then we have to have the mobilizing for 'Change on Alcohol' in our universities. This conclusion should provide grounds for future studies of strategies for health promotion and of prevention measures for psychological ill-health of nursing students.

Purpose: To search the salivary factors that objectively indicate an pain in myalgia patients with temporomandibular joint disorder (TMD) and determine the possibility of the factors as pain-biomarkers. Methods: Participants consisted of pain-free 15 persons (male 7, female 8, mean age±standard deviation (SD); 26.8±16.04 years) and 45 myalgia patients with TMD (male 21, female 24, mean age±SD; 27.98±13.01 years). They were divided into a pain-free group (numerical rating scale [NRS] score 0), a mild pain group (NRS 1-4), a moderate pain group (NRS 5-6), and a severe pain group (NRS 7-10) and members of all groups were age, sex matched. Interleukin-8 (IL-8) and matrix metalloprotease 9 (MMP-9) were selected as pain biomarkers, by searching the Gene Expression Omnibus database and analyzing pain-related genes. Enzyme-linked immunosorbent assays were used to measure the concentration of IL-8 and MMP-9 in the patients' saliva. Results: IL-8 and MMP-9 levels were statistically significantly higher in pain groups than in the pain-free group. Greater differences were observed in patients with acute pain (with painful duration under 3 months) than in the control group and in female patients than in male. Conclusions: Salivary IL-8 and MMP-9 may play a role as biomarkers of myalgia in patients with TMD.

Purpose: The purpose of this study were to describe the level of activities of daily living (ADLs) and fatigue of stroke patients and to identify related factors of ADLs and fatigue. Method: A sample of 132 were used who were recovering from stroke. The face-to-face interviews were conducted to collect data. The levels of ADLs and fatigue were evaluated using the Modified Barthel Index and Kim's fatigue scale respectively. A series of t-test and analysis of variance analyses were conducted to examine study purposes using SPSS 15.0. Results: The levels of fatigue and ADLs were 65.6 (SD=16.52) and 74.6 (SD=22.32) respectively. Significantly poorer ADLs were found: women (t=2.05, p=.001), older people aged ${\geq}$ 70 years (F=2.74, p=.046), the duration of onset (F=4.34, p=.006), the use of assist devices (F=35.64, p<.001), the parts of paralysis (F=4.25, p=.007), the time to attack (F=3.34, p=.039), and accompanying symptoms (F=15.23, p<.001). There was a significant difference in fatigue with patients with lower accompanying symptoms having lower fatigue (F=11.08, p<.001). Conclusion: These findings suggest gender, the duration from onset, the use of assist device, the parts of paralysis, the time to attack and accompanying symptoms were significant factors of the ADLs and fatigue post stroke. These factors should be considered when developing and testing nursing intervention programs for stroke survivors.
