The purpose of this study was to identify the effect of providing toothbrushing by professionals as part of oral hygiene education for the elderly. We randomly visited 12 centers in the metropolitan city and analyzed the data of 114 participants among 310 early registrants aged >65 years, who participated in the study at all 3 time points. The subjects were categorized into an experimental group (odd-numbered visits) and a control group (even-numbered visits). Oral hygiene practices were provided for both experimental and control groups, but professional toothbrushing was performed in a different manner in the experimental group. Differences in plaque index (PI) according to the subjects' general characteristics and oral health status were assessed using the t-test, and the effect of PI difference between the experimental and control groups was assessed by repeated measure two-way analysis of variance. A stepwise multiple regression analysis was used to analyze factors affecting the PI. At baseline, the mean overall PI was 61.82. In both experimental and control groups, the PI significantly reduced from the baseline (p<0.01). At 5 weeks, the experimental group showed a decrease of 27.16 points from the baseline, and the 10-week PI was similar to the 5-week PI. The control group showed a decrease of 14.87 points from the baseline, and the PI increased by 5.74 points at 10 weeks. PI-related factors were gender and self-xerostomia. The PI was lower in the female group and the group with self- xerostomia (p<0.01). It is important to select an appropriate method to educate elderly subjects on proper removal of dental plaque and to habituate correct behavior, which requires inclusion of a direct toothbrushing intervention by a specialist.

Objectives : To develop a Korean version of VSSS-82 for measuring the multi-dimensional satisfaction with community-based mental health services in psychiatric patients and to investigate both the reliability and validity of the Korean version. Methods : The VSSS-82 English version was translated and back-translated with some modification. Data from 68 psychosis patients using community-based mental health services in three Community Mental Health Centers (CMHCs) was collected through a personal interview survey regarding the satisfaction and suitability of service. Variability of satisfaction and internal consistency, discriminant validity, and concurrent validity of the VSSS-82 Korean version were evaluated. Results : A higher number of dissatisfied subjects and significant pairwise differences for the dimensions were found. The Crohnbach's alpha coefficient, a measure of internal consistency, ranged from 0.56(overall satisfaction) to 0.90(skills and behavior) and significant differences in satisfaction was found in patients by the self-rated suitability of service. Conclusions : The VSSS-82 Korean version is a reliable and valid instrument for measuring multi-dimensional satisfaction with community-based mental health service.

Background. Although there have been a great number of research studies based on the model of uncertainty in illness, few studies have considered the appraisal portion of model. Purpose. The purpose of this study was to test the mediating effect of appraisal in the model of uncertainty in illness. Additionally, this study aimed to examine the relationships among uncertainty, symptom severity, appraisal, and anxiety in patients newly diagnosed with atrial fibrillation. Methods. This study employed a descriptive correlational and cross-sectional survey design using a face-to-face interview method. Patients diagnosed with atrial fibrillation within the previous 6 months prior to data collection were interviewed by Mishel Uncertainty in Illness Scale-Community Form, appraisal scale, Symptom Checklist-Severity V.3, and State Anxiety Inventory. Results. A total of 81 patients with atrial fibrillation were recruited from two large urban medical centers in Cleveland, Ohio, U.S.A.. Symptom severity was the significant variable in explaining uncertainty ($\beta$=0.34). Individuals with greater symptom severity perceived more uncertainty. Uncertainty was appraised as a danger rather than opportunity, and those with greater uncertainty appraised a greater danger (p<.0l). While the appraisal of opportunity had the negative relationship with anxiety (r=-0.25), the appraisal of danger was positively associated with anxiety (r=0.78). The measure of goodness of fit (Q) of the model was .7863, and the significant test (X$^2$) for the Q was statistically significant (df =3, p<.00l). Accordingly, the overall mediating model of uncertainty in illness was proven not to be fit to the empirical data of patients with atrial fibrillation. Consequently, the mediating effect of appraisal was not supported by the empirical data of this study. Conclusion. The findings of this study were discussed in terms of their relevance compared with those of previous studies or theoretical framework and the plausible explanations on study findings. Lastly, in order to expand the present body of knowledge on uncertainty in illness model, recommendations for the future nursing studies were included.

Purpose: The purpose of this study was to identify the effects of health status and health management on activities of daily living (ADL) in older, urban-dwelling Koreans. Methods: A total of 206 subjects were recruited from one senior welfare center, six senior citizen centers, and subjects' home in two cities. Data was collected with self-reported questionnaires in order to measure health management, health status, and ADL. Data was analyzed by t-test, ANOVA, and stepwise multiple linear regression using SPSS/WIN 22.0. Results: ADL in this subject were different depending on their age, education, marital status, type of family, and average monthly living expenses. Multivariate analysis showed that age (${\beta}=-0.35$, p<.001), exercise ability (${\beta}=0.20$, p<.001), diabetes (${\beta}=-0.17$, p<.001), osteoarthritis (${\beta}=-0.15$, p<.001), caregiver (${\beta}=0.14$, p=.005), frequency of health management (${\beta}=-0.13$, p=.006), smoking (${\beta}=-0.11$, p=.019), hypertension (${\beta}=-0.10$, p=.027), and type of family (${\beta}=-0.10$, p=.036) were significantly associated with ADL. Overall, approximately 60.2% of total variability in ADL could be explained by the 11 variables in this model ($R^2=0.602$, F=32.06, p<.001). Conclusion: This study suggests that individualized health care should be continued for older, community-dwelling Koreans in order to improve their ADL. Moreover, we need to develop self-care programs and encourage them to participate in those programs.

Purpose: To examine the levels of the disease-related knowledge and educational demands of pre-dialysis, chronic renal failure patients at different GFRs and stages. Methods: This study used a cross-sectional survey and aimed at 116 pre-dialysis, chronic renal failure patients, who were registered and received regular treatment from December 1 to December 31, 2009 at the nephrology departments of tertiary medical centers in Seoul. Stages were classified into Stage 3, 4 and 5 depending on GFR ranges. To measure the levels of knowledge and educational demands, the tool, which were first invented by Young Ae Lim (1996) and then modified by Hyo Sun Lim (2005) to adjust the knowledge and educational demands measuring tool for hemodialysis patients to pre-dialysis patients with chronic renal failure, was used. Collected data was analyzed with the SPSS WIN 12.0 program (average, standard deviation, Pearson's correlation coefficient, t-test and ANOVA). Results: There was a significant difference in the disease-related knowledge levels of the subjects at each stage (F=24.41, p=.000). The Scheffe post hoc test confirmed that patients at higher stages had higher levels of knowledge of their disease. Also, although the results showed that patients at higher stages had higher educational demands, there was no significant difference among the groups (F=1.259, p=.288). Conclusion: As patients have different levels of knowledge of the disease and educational demands depending on their stages, it is important to develop and use a systematic education program that reflects the demands and levels of patients at each stage in order to help pre-dialysis patients with chronic renal failure with self-management and improve their quality of life.

Objectives: The aim of this study was to measure secular trends in health risk behaviors among middle and high school students in Korea between 2005 and 2009 by using data from the Korea Youth Risk Behavior Web-based Survey(KYRBS). Methods: The analyses were performed using data from the 2005, 2006, 2007, 2008, and 2009 KYRBS, which included a nationally representative sample of middle and high school students. A total of 34 health behavior indices were used for the assessment of secular trends in health risk behaviors. Logistic regression models were used to identify statistically significant secular trends in health risk behaviors, after adjusting for gender and grade. Linear and higher-order time variables were simultaneously entered into the statistical models. Results: There was evidence of small, but statistically significant increasing or decreasing trends in certain health risk behaviors. Secular trends in health risk behaviors varied by gender. Conclusions: This study indicates that between 2005 and 2009, changes in health risk behaviors among Korean adolescents were generally small, but represented statistically significant increases or decreases. Further research should explore why certain health risk behaviors are increasing or decreasing and what types of interventions are most effective.

Objectives: This study was conducted to evaluate the nutrition quotient (NQ) by gender and understand which factors influence NQ in preschool children. Methods: Subjects were 245 children (110 boys, 135 girls) aged 4-6 years and their parents. The questionnaire composed of demographic characteristics, eating behavior factors and the NQ questions. The NQ consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Inbody J05, a measurement device that measures individual's body composition was used to measure children's anthropometric data. All data were statistically analyzed by SPSS program (Ver. 20) and the statistical differences in variables were evaluated by Student t-test, ${\chi}^2-test$, One-way ANOVA and Duncan's multiple range test. Results: The total NQ score of the subjects was 65.3. The NQ score of girls (67.0) was significantly higher than that of the boys (63.2) (p<0.01). The girls' average scores of NQ factors including diversity (p<0.01) and practice (p<0.05) were higher than those of the boys. The analysis of related-factors influencing NQ scores showed that there was a significant difference among the groups according to feeding methods during infancy (p<0.05), breast feeding group being the highest. Furthermore, the NQ score showed a significant difference depending on how to correct children's unbalanced diet as well as parents' nutrition knowledge. The NQ score of obesity group tended to be lower than that of underweight group although there was no significant difference. Conclusions: Overall results indicated that the girls had better quality of diet and eating habits than the boys. Children and their parents need proper nutrition education and counseling to correct children's eating habits and to improve diet quality in kindergartens and in children care centers.

PURPOSE: This study was aimed at investigating the types of gender roles and the relationship between gender roles and job satisfaction among neurological physical therapists. METHODS: The study subjects were 169 (male 74, female 95) neurological physical therapists working at general hospitals or rehabilitation centers in the Daejeon Metropolitan City area, South Korea. To identify job satisfaction scores, the subjects completed a questionnaire, and a vernier caliper was used by a trained examiner to measure the lengths of the subjects' index and ring fingers (i.e., digitus secundus manus and digitus annularis, respectively) to examine gender roles. The index to ring finger length ratio (i.e., 2D:4D ratio) was calculated using a personal computer. An independent t-test was performed to compare the finger length ratio and job satisfaction of male group with that of the female group and a correlation analysis was performed to examine job satisfaction by gender roles. RESULTS: Finger length ratio is lower in males than in females. However, there was no significant difference statistically (p>.05). Regarding job satisfaction by gender, males were more satisfied with their jobs than females (p<.05). However, there were no significant correlations between job satisfaction and gender roles (p>.05). CONCLUSION: It cannot be concluded that bias against gender roles is a contributing factor for neurological physical therapists being satisfied with their job, and thus bias against gender roles among neurological physical therapists should be removed.

The most satisfactory split-beam transducer for fish sizing maintains a wide bearing angle region for correct fish tracking without interference from side lobes and lower sensitivity to fish echoes outside of the main lobe region to correctly measure the angular location of free-swimming fishes in the sound beam. To evaluate the performance of an experimentally developed 50 kHz split-beam transducer, the angular location of a target was derived from the electrical phase difference between the resultant signals for the pair of transducer quadrants in the horizontal and vertical planes consisting of 32 transducer elements. The electrical phase difference was calculated by cross-spectral density analysis for the signals from the pair of receiving transducer quadrants, and the directivity correction factor for a developed split-beam transducer was estimated as the fourth-order polynomial of the off-axis beam angle for the angular location of the target. The experimental results demonstrate that the distance between the acoustic centers for the pair of receiving transducer quadrants can be controlled to less than one wavelength by optimization with amplitude-weighting transformers, and a smaller center spacing provides a range of greater angular location for tracking of a fish target. In particular, a side lobe level of -25.2 dB and an intercenter spacing of $0.96\lambda$($\lambda$= wavelength) obtained in this study suggest that the angular location of fish targets distributing within a range of approximately ${\pm}28^{\circ}$ without interference from side lobes can be measured.

Purpose: The purpose of this study was to develop a parents education program for early childhood health care and to measure its effects. Methods: This study was a quasi experimental study following a pretest-posttest design model. The subjects were 264 parents who had children aged 0-5 years in 7 rural districts or in the city. The content of this program was child development and management, and the management for health and disease for and emergency care. Parent education was performed by 7 nursing professors in each area, including 2 education sessions. Data were twice collected using a questionnaire, i.e. before the first session and after the second session. Data were analyzed by using the SAS software version 9.1. Result: The hypothesis of this study was that "the parents' score will improve after education". Our hypothesis was supported (t=7.30, p=<.0001). We found corelation in occupation and past experience of similar education. The contentment of education was higher than 90%. Conclusion: The systematic parents education program was very useful and effective, in raising the level of contentment of subjects. There is the needed for the social opportunity of parents' education program to be extended and emphasised by public support.
