There is a lack of survey standard for cross-to-nature small stream. In this research, we analyzed cross sectional survey data of Sanggachun stream, calculated variant quantity of soil, and suggested a survey interval. Descriptive analysis of cross sectional survey data shows the trend of stabilization; mean interval of survey is 14.91m(min: 7.0m, max: 39m), mean cross sectional variances are $0.82m^2$(min: $-3.80m^2$, max: $8.11m^2$) in 2004, $0.24m^2$ (min: $-5.25m^2$, max: $8.55m^2$) in 2005. Calculating results of variance quantity based on data of 65 cross sections show similar trends in 15m, 30m, 45m, 60m but different with results of 75m, 90m with Post-Hoc Test in statistical verification. We suggested standard cross sectional survey length of cross section for natural style small stream as 50m based on fitting results of standard variation of erosion and cumulation quantity by survey interval.

In a previous proteomic study, heat shock protein beta 1 (HSPB1) was detected as differentially expressed protein in longissimus thoracis between low (grade 3) and high (grade 1++) meat quality groups by 2DE gel electrophoresis. The present study investigated an association of HSPB1 expression at the level of gene and protein with Warner-Bratzler shear force (WBS) measured in 20 Hanwoo steers. An analysis of variance (ANOVA) between expression values and WBS showed that WBS was affected by HSPB1 expression (p<0.05). The expression (at both gene and protein level) of the HSPB1 was 2 times higher in the low WBS group than that in the high WBS group (p<0.01). This result suggests that the HSPB1 gene may be a candidate gene associated with tenderness in longissimus thoracis of Korean cattle.

Atopic dermatitis is the fastest growing skin disorder among children from infancy to adolescence in Korea. The side-effects of atopic dermatitis not only include physical discomfort, but also psychological trauma which ultimately affects the developmental growth of children. This study was conducted in order to investigate the behavioral characteristics of an atopic dermatitis sufferer. As part of this research, the relative influence of behavioral problems and, self-perceived competence were analyzed in relation to the social competence of an atopic child. In total, 301 atopic and non-atopic children, between 2 and 6 years of age, and their mothers and teachers participated in the study. From this number, 109 children had atopic dermatitis, while 192 children did not. Mothers were asked to complete a parent-report questionnaire that required information on parental stress, according to the scale parenting methodology of Abbdin(1990) and Cho(1999). Teachers were subjected to teacher-report questionnaires which included topics on social competence, socia-emotional assessment and behavioral problems of an atopic child. Furthermore, children also completed questionnaires on self-perceived competence. According to analysis on K-CBCL, ITSEA, social competence, self-perceived competence and parental stress, children with atopic dermatitis showed higher scores in depression/anxiety and depression/withdrawal, compared to children in the normal control group. In relation to parental stress, daily stress, parental role stress, and stress related disease, mothers with atopic dermatitis children exhibited higher scores. In establishing relationships among the related variables, atopic children who demonstrated more social competence were more likely to suffer less from withdrawal, attention problems, and depression/anxiety. Stress related disease in mothers with atopic children was positively related to attention problems of the child. In terms of relative influences, behavioral problems was the most significant variable, accounting for 23% of variance. Lower behavioral problems was positively related to more social competence. In summation, this study investigated the general characteristics of atopic children. In conclusion, atopic children and their mothers had difficulty in dealing with this disease. It is our belief that an atopic child would not only require physical treatment, but also need appropriate psychological care.

Overexcitaility (OE) as a concept that is related to developmental potential, has been shown to differ by intelligence, gender, involvement in school programs and artistic interest in American populations of students. Overexitability, used to describe the five ways that people might experience developmental potential for emotional growth, are emotional, intellectual, imaginational, sensual, and psychomotor. Little is known about the profiles of groups of gifted learners outside of studies conducted in the United States. In order to better understand the emotional needs of Korean students, the purpose of this study was to determine the overexcitability profiles of students enrolled in four high schools, each with a different domain focus: math and sciences, visual and performing arts, and foreign languages. 341 subjects of this study completed the Overexcitability Questionnaire II. Multivariate Analysis of Variance (MANOVA) was conducted to determine statistical differences. The results showed that Mean scores of psychomotor, sensual and imaginational are highest in the Art High School, intellectual is highest in the Science High School and emotional is highest in the Foreign Language High School. There were significant differences among the schools. Each major also showed significant difference. The results showed that mean score of psychomotor is highest in the Dance major, sensual, imaginational and emotional are highest in the Drama majore and intellectual is highest in the Science major. The results showed that the mean scores of psychomotor, imaginational and intellectual are higher in the male students than female students. On the other hand the mean scores of sensual and emotional are higher in the female students than in the male students.

The purpose of this study was to examine the impact of the Sport Talent Development Environment on the Achievement Goal in Sport of college athletes. The Sport Talent Development Environment (Martindale et al., 2010) had seven factors, but only four factors (long-term development, lack of quality preparation, communication, lack of understanding) were used after exploratory factor analysis. The Achievement Goals in Sport (Wang et al., 2007) was composed of four factors (mastery approach, mastery avoidance, performance mastery, performance avoidance). The results showed that 1)long-term development factor and communication factor of male athletes were significantly higher than female athletes while lack of understanding factor of female athletes were significantly higher than male athletes, 2)mastery avoidance factor of female athletes was significantly higher than male athletes, and 3)factors of development environment accounted for 27.8% to 34.5%-male athletes and for 13.2% to 22.7%-female athletes variance in the four achievement goals. Therefore, it is important for coaches and sport administrators to take these results into consideration when designing an effective talent development program.

The purpose of this study was to investigate the effect of applying whole body vibration exercise at 30 Hz on the thickness and mechanical properties of the erector spinae. The study population included 24 adults (11 male and 13 female) in the N region. The subjects were divided into two groups, a 30Hz whole body vibration exercise(WG, n=12) and an LSG(12 subjects). Changes in the thickness and mechanical properties of the erector spinae were analyzed before the exercises and after four and eight weeks of exercises using a two-way repeated analysis of variance with a statistical significance level of α=0.05. When there was an interaction between the groups and measurement times, post hoc analyses were conducted at a statistical significance level of α=0.01. The thickness, frequency, stiffness and strain of the erector spinae muscles were significantly different in each time period and in the interaction between time period and the group (P<0.05), and recovery was significantly different only in each time period (P<0.05). Thus, 30Hz whole body vibration exercise had a positive effect on the thickness and mechanical properties of the erector spinae. The results of this preliminary study suggest that whole body vibration exercise may find a place as a lumbar stabilization exercise in clinical practice in the future.

Background: The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O₂-O₃) injection in patients with chronic supraspinatus tendinopathy. Methods: Participants were randomly assigned to the corticosteroid group (n = 22) or ozone group (n = 22). Injections in both groups were administered into subacromial bursa with an US-guided in-plane posterolateral approach. Primary outcome measure was the change in the Western Ontario Rotator Cuff Index (WORC) score between baseline and 12-weeks post-injection. Secondary outcome measures included visual analog scale and Shoulder Pain and Disability Index scores. Assessments were recorded at baseline, and 4-weeks and 12-weeks post-injection. Results: Forty participants completed this study. Based on repeated measurement analysis of variance, a significant effect of time was found for all outcome measures in both groups. Both the groups showed clinically significant improvements in shoulder pain, quality of life, and function. Baseline, 4-week post-injection, and 12-week post-injection WORC scores (mean ± standard deviation) were 57.91 ± 18.97, 39.10 ± 20.50 and 37.22 ± 27.31 in the corticosteroid group, respectively and 69.03 ± 15.89, 39.11 ± 24.36, and 32.26 ± 24.58 in the ozone group, respectively. However, no significant group × time interaction was identified regarding all outcome measures. Conclusions: Three-time ozone injection was not superior to a one-time corticosteroid injection in patients with chronic supraspinatus tendinopathy. It might be as effective as corticosteroid injection at 4-weeks and 12-weeks post-injection in terms of relieving pain and improving quality of life and function.

Cervical cytology has been widely used as a screening tool for cervical cancer. However, Human papillomavirus (HPV) detection and subtype testing are suggested to overcome the high false-negative rate associated with cytology. We aimed to investigate the clinical usefulness and infection rate in the HPV polymerase chain reaction (PCR) test performed in hospitals. HPV PCR data from 217 patients were analyzed. Analysis of variance revealed a significant difference in the infection rate among different age groups (P=0.015). The biopsy results showed that epithelial cell abnormalities and high HPV-positivity rate was observed in 1 (100%) subject aged <29 years, in 4 out of 5 (80%) patients in their 30s, and in 3 out of 4 (75%) patients aged ≥70 years. The prevalence of HPV infection was very high (46.1%). The highest prevalence (87.5%) was observed among patients in their <29, followed by those in their 30s (67.7%) and those in their 40s (31.9%).A high rate of epithelial cell abnormalities (≥ cervical intraepithelial neoplasia type 1, mild dysplasia) was observed in HPV-infected women aged<30 years. Therefore, extensive research and prevention activities are needed in this age group. HPV PCR testing is recommended to complement cervical cytology

Objectives: The purposes of this study were to investigate CHPs' knowledge, attitude, and practice regarding UI, and to identify predictors of their UI related practice. Methods: A descriptive-correlational study using self-administered questionnaire was conducted. A total of 330 members of the local Korean Association of CHPs were included in this study. A mailed survey was conducted to collect data. Findings: Of CHPs surveyed, 170(51.5%) returned completed questionnaire. Educational preparation of CHPs regarding UI was limited. The mean correct score of knowledge scale was 68.96%. Overall, CHPs exhibited positive attitudes toward UI. CHPs in this study were not actively participate UI related practice. Contrary to expectation, knowledge was not significantly related to CHPs' practice regarding UI. In the final analysis, CHPs' practice regarding UI was predicted by attitude toward the care of UI clients and educational needs for UI and these two variables explained 9% of variance of UI related practice. Conclusion: The results of this study suggest the importance of attitude and educational needs in shaping UI related practice among CHPs. To facilitate UI related practice among CHPs, efforts for attitudinal change related to UI among CHPs are needed. Moreover, continuing educational program for UI management should be developed, applied and evaluated.

This study aims to develop a scale to measure the elderly's intention on home renovation and to verify its validity. As a methodological study based on the theory of planned behavior, this study provides 26 preliminary items in the pre-test. The first main test, performed to verify the content validity of the developed items, was followed by a second test of construct validity and reliability. As the result of the content validity test targeting experts, some of the original 26 items were excluded, while others were combined for a total of 22. As the result of the construct validity test of the scale, targeting the elderly aged 65 and over, the 22 items were narrowed down to 14 items, excluding the items that were unsuitable for communality and Eigen value. After once more conducting a factor analysis, the items were classified into five factors with a total cumulative variance of 72.5% and a Cronbach's α of 0.75. This study will contribute to the discussion of housing for the elderly by giving force to environmental regeneration activities through facilitating the identification of the home owners' intentions to renovate in order to improve the physical environment in decayed areas at a public level.
