This study is a descriptive paper addressing the relationship between test anxiety, self-esteem and the mental health levels of freshmen and third year students of Dental Hygienics. In late 2011, we received a total of 298 questionnaires from freshmen and third year Dental Hygienics students of three South Korean universities, located specifically in Seoul and Gyeonggi-do. The timing of this questionnaire was significant because it was one week prior to midterm examinations. The results were as follows:1. There was a statistically significant relationship between age (t=3.017, p<.001) and grade(t=2.665, p<0.05), subjective health status(t=27.513, p<.001). 2. The lower the participants' reported mental health in general, the higher their level of test anxiety (r=.565, p<.001), broken down into two subdivisions: cognitive text anxiety (r=526, p<.001) and emotional test anxiety (r=.534, p<.001). 3. When considering the factors that influence the general mental health of participants, there were age differences. For first year students, their subjeetive health status (${\ss}$=-.300, p<.001) and test anxiety (${\ss}$=.530, p<.001) were significant. For third year students, this was also true (subjective mental condition: ${\ss}$=-.242, p<.001 and test anxiety: ${\ss}$=.350, p<.001) but self-worth was also significant (${\ss}$=.377, p<.001). The results of this study suggest that the key factors that influence the mental health level of students Dental Hygienics are test anxiety, subjective appraisal of health level, and general self-worth. A systematic approach is therefore needed to improve students' mental health and reduce test anxiety. Health management programs which address and test students' physical health will also be important in improving student performance and welfare.

Purpose: This study examined the correlations among family support, morale, and quality of life in the elderly. Methods: Descriptive correlational study design was used. The subjects were 131 elderly people 65 and older who have lived in Seoul and other three cities. The data were analyzed with mean, SD, t-test, ANOVA, and pearson's correlation by using the SPSS 11.0 program. Results: First, the mean of family support was 3.71, morale 3.25, and quality of life 3.02 respectively. Second, the correlation between quality of life and family support was statistically significant(r=.264, p=.00), the correlation between quality of life and morale was also statistically significant(r=.484, p=.00), and the correlation between family support and morale was also statistically significant(r=.430, p=.00). Conclusion: Family support for the elderly in the study was confirmed as the primary important concept which can positively maintain and promote the quality of their life. Also, the correlation between morale and family support was verified as significant. Further study is needed to develop a nursing intervention program for morale improvement with a network of family support with their children, ultimately for quality of life among the elderly.

Purpose: This study was done to compare clinical nurses' knowledge and visual differentiation diagnostic ability for the pressure ulcer classification system (PUCS) and incontinence-associated dermatitis (IAD). Methods: A convenience sample of 602 nurses took the pressure ulcer classification system and incontinence-associated dermatitis knowledge test (PUCS & IAD KT) and completed the visual differentiation tool (VDT), consisting of 21 photographs with clinical information. Results: The overall mean score for correct answers was 14.5 (${\pm}3.2$) in PUCS & IAD KT and 11.15 (${\pm}4.9$) in PUCS & IAD VDT. Incorrect responses were most common for statements related to stage III, IAD for PUCS & IAD KT, and suspected deep tissue injury (SDTI), unstageable, and stage III for PUCS & IAD VDT. Significant correlations were found between PUCS & IAD KT and VDT (r=.48, p<.001). Factors affecting scores for PUCS & IAD VDT were PUCS & IAD KT, frequency of pressure ulcer, IAD management and participation in wound care education programs. Conclusion: Results indicate that nurses have an overall understanding of PUCS & IAD, but low visual differentiation ability regarding stage III, SDTI, and unstageable ulcers. Continuing education is needed to further improve knowledge and visual differentiation ability for PUCS & IAD.

During our on-going studies to identify bioactive compounds in medicinal herbs, we found that saucerneol F (SF), a naturally occurring sesquilignan isolated from Saururus chinensis (S. chinensis), showed in vitro anti-inflammatory activity. In this study, we examined the effects of SF on the generation of 5-lipoxygenase (5-LO) dependent leukotriene $C_4$ ($LTC_4$), cyclooxygenase-2 (COX-2) dependent prostaglandin $D_2$ ($PGD_2$), and on phospholipase $C{\gamma}1$ ($PLC{\gamma}1$)-mediated degranulation in SCF-induced mouse bone marrow-derived mast cells (BMMCs). SF inhibited eicosanoid ($PGD_2$ and $LTC_4$) generation and degranulation dose-dependently. To identify the molecular mechanisms underlying the inhibition of eicosanoid generation and degranulation by SF, we examined the effects of SF on the phosphorylation of $PLC{\gamma}1$, intracellular $Ca^{2+}$ influx, the translocation of cytosolic phospholipase $A_2$ ($cPLA_2$) and 5-LO, and on the phosphorylation of MAP kinases (MAPKs). SF was found to reduce intracellular $Ca^{2+}$ influx by inhibiting $PLC{\gamma}1$ phosphorylation and suppressing the nuclear translocations of $cPLA_2$ and 5-LO via the phosphorylations of MAPKs, including extracellular signal-regulated protein kinase-1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38. Taken together, these results suggest that SF may be useful for regulating mast cell-mediated inflammatory responses by inhibiting degranulation and eicosanoid generation.

Objective: The purpose of this study was to compare muscle activities of stroke patients and healthy participants during bimanual tasks. Design: A cross sectional study. Methods: A total of 25 participants (13 hemiparetic stroke patients and 12 healthy participants) were recruited. The muscle activities using electromyogram (EMG) during bimanual tasks were collected from the following muscles: extensor carpi radialis longus (ECRL), biceps brachii (BB), and triceps brachii (TB). The bimanual tasks included eight tasks consisted of (1) raising the wrists up and down, (2) supinating and pronating the palms, (3) touching the shoulder with fingertips, (4) drawing vertical dot, (5) reaching for a cup and bring it in to drink, (6) drawing a circle outward and (7) inward, and (8) grasping the fingers. The EMG data collected from the muscles of paretic and non-paretic sides of stroke patients and the average from both sides of healthy subjects were normalized and compared after calculating the percentage of maximal isometric voluntary contraction. Results: The ECRL, BB and TB of the paretic side of the stroke patients showed relatively greater muscle activity compared to the non-paretic side as well asaverage of the healthy subject duringall tasks (p<0.05). In addition, the ECRL showed the highest muscle activity during most of the tasks. All of the non-paretic side musclesfrom stroke patients showed higher muscle activity compared to those of healthy subjects. Conclusions: The current study showed that muscle activities of upper extremity varied between paretic and non-paretic sides of stroke patients during bimanual tasks. Interestingly, the non-paretic side muscle activities were also different from those of normal participants.

BACKGROUND/OBJECTIVES: While many obesity studies have pointed out the importance of meal regularity, few have conducted empirical analyses using data from food diaries. We examined the association between meal regularity (i.e., meal time regularity [MTR] and calorie intake regularity [CIR]) and weight loss. SUBJECTS/METHODS: We collected food diary data from 637 women who had participated in commercial weight loss programs for 28-168 days (4-24 weeks). This study defined "meal regularity" in terms of two concepts: MTR and CIR. MTR refers to how regularly people eat their meals (i.e., at certain times each day), whereas CIR refers to how regularly people consume a certain amount of calories at each meal. We conducted multiple regression analyses. RESULTS: MTR (model 1: β = -2,576.526, P < 0.001; model 2: β = -1511.447, P < 0.05; model 3: β = -1,721.428, P < 0.05) and CIR (model 1: β = -1,231.551, P < 0.01; model 2: β = -2,082.353, P < 0.001; model 3: β = -1,343.490, P < 0.01) turned out to be significant determinants of the amount of weight loss in breakfast, lunch, and dinner contexts. While meal regularity (i.e., MTR and CIR) was significantly associated with weight loss, daily calorie intake from meals was not significantly associated with the amount of weight loss (model 1: β = 0.13, P > 0.05; model 2: β = 0.11, P > 0.05; model 3: β = 0.14, P > 0.05). Subjects who consumed an equal amount of calories per meal throughout the day lost more weight than those who did not (model 4: β = -3,675.51, P < 0.001). CONCLUSIONS: Eating each meal (i.e., breakfast, lunch, and dinner) at a certain time every day may increase weight loss success. Also, consuming the same amount of calories at each meal may help weight loss success.

Purpose: Matrix metalloproteinases (MMPs) have been implicated in atherosclerosis, and therefore, are considered risk factors for metabolic dysfunction in adults. However, there is little data on circulating levels of MMPs and tissue inhibitors of MMPs (TIMPs) with regard to obesity-related biomarkers in the general adolescent population. In the present study, we determined the associations of MMP-8, MMP-9, and TIMP-1 levels and MMP-8/TIMP-1 and MMP-9/TIMP-1 ratios with obesity-related biomarkers in apparently healthy adolescent boys. Methods: We measured MMP and TIMP concentrations in plasma samples using the enzyme-linked immunosorbent assay and analyzed their associations with obesity-related biomarkers, such as liver enzymes and lipid profiles, in a sample of 91 Korean boys aged 13-14 years who participated in a general health check-up. Results: The mean age of the boys was $13.8{\pm}0.3years$; 72 boys were normal weight and 19 were overweight/obese. The Pearson correlation coefficients revealed a significant correlation between MMP-8 and aspartate aminotransferase (r=0.217, P=0.039) and alanine aminotransferase (r=0.250, P=0.017) and between TIMP-1 and aspartate aminotransferase (r=0.267, P=0.011). In a multivariate linear regression analysis, serum alanine aminotransferase was positively associated with the MMP-8 level. There were no significant differences in the MMP-8, MMP-9, and TIMP-1 levels or MMP-8/TIMP-1 and MMP-9/TIMP-1 ratios between control and overweight/obese subjects. Conclusion: We found a significant association between the MMP-8 level and alanine aminotransferase in the apparently healthy adolescent boys. These findings indicate that there may be a pathophysiological mechanism underlying the relationship between MMP-8 and liver enzymes in young adolescents.

Purpose: To determine the effect of marketed multipurpose contact lens solutions (MPSs) on human corneal epithelial cells (HCEpiCs) toxicity by using image analysis. Methods: HCEpiCs were exposed six MPSs (product A-F) at 0.05~50% for 2h, 12h, 24h, and 48h respectively. HCEpiCs were fixed and stained with Draq5 after exposure with MPSs, and the cell viability and apoptosis were evaluated by using confocal microscope and ImageXpress UltraTM. Results: Viabilities of HCEpiCs exposed to MPS A-F for a 2h were not affected, while reductions (52~75%) in cell viability over a 12h exposure of MPS B, MPS C, MPS D and MPS F, and significant more reductions (29~73%) over a 24h and 48h-exposure. Apoptosis of HCEpiC was not affect over a 12h MPS exposure, however was significantly increased (199~526%) over 24h and 48h MPS exposure. Among the products MPS D, E and F reduced viability of HCEpiCs and apoptosis increased more than MPS A (p<0.05). Conclusions: Lower concentration of MPSs have not an cytotoxic effect on HCEpiCs, however higher concentration of MPSs induce apoptosis and reduce viability of HCEpiCs. Therefore, it need to develop MPS having antimicrobial effectiveness with low cytotoxicity.

Purpose: The purpose of the study was to identify women's osteoporosis knowledge, concerns about osteoporosis factors, and health behavior as well as to examine the relationship between these variables. Methods: The participants were 394 women in the Jeonbuk area. The data were analyzed using a t-test, ANOVA, Duncan test, and hierarchical regression analysis with SPSS v. 24.0. Results: The score for osteoporosis knowledge was 6.21 points out of a possible 12, the score for concern about osteoporosis factors was 26.50 points out of a possible 40. The score for the health behavior was 57.26 points out of a possible 85. The knowledge showed significant differences according age (p < 0.01), income (p < 0.05), education level (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.05), and osteoporosis information (p < 0.01). The concern showed significant differences according to age (p < 0.001), income (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.001), family history of osteoporosis (p < 0.05), and calcium medications (p < 0.001). The health behavior showed significant differences according to age (p < 0.001), income (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.01), and calcium medications (p < 0.01). Regression analysis showed that the concern about osteoporosis factors was the most influential variable on health behavior, followed by health interest of the subjects, age, and the osteoporosis knowledge. Conclusion: Therefore, it is necessary to consider educational programs on increasing interest in osteoporosis according to the age and health for improving the health behavior to prevent osteoporosis.
