The aim of this study was to determine the effect of a non-elastic fixation belt on the balance ability and fall prevention in elderly women. Elderly women experience reduced balance ability and an increased risk of falls due to a weakening of the surrounding sacroiliac joint and pelvic muscles during childbirth and menopause. On the other hand, specific studies are still needed. The subjects were allocated randomly to two groups: control (n=20) and experimental (n=20). The experimental group used a non-elastic fixation belt, whereas the control group had no fixation belt. The balance ability and the fall index were measured in all subjects using a balance measurement device, and the low abdominal muscle thickness was determined in the experimental group using ultrasound imaging for the exact application of the non-elastic fixation belt. The following statistical analysis was performed: an independent t-test for the general characteristics of the subjects, $2{\times}2$ analysis of variance with repeated measures for the balance and fall index score, and a paired t-test for the abdominal muscle thickness. The group ${\times}$ time interaction effect showed significant improvement in the General Stability Index (F1,38=47.24, p=0.001), Fourier Harmony Index (F1,38=88.83, p=0.001), Weight Distribution Index (F1,38=50.21, p=0.001), and Fall Index (F1,38=21.59, p=0.001). The thicknesses of the transverse abdominal (p=0.001) and internal oblique (p=0.001) muscles were increased significantly in the experimental group after using the non-elastic fixation belt. Overall, the application of a non-elastic fixation belt could be effective in improving the balance ability and fall prevention in elderly women.

The purpose of this study is to investigate the effect of product selection of hospital workers cosmeceutical cosmetics on marketing communication among hospital workers who use cosmeceutical cosmetics that have emerged in line with the recent growing medical skin care field.Coping with complaints from consumers who buy cosmeceutical cosmetics in hospitals where cosmeceutical cosmetics are mainly used and sold, and minimizing the influence of negative issues will potentially strengthen consumer relationships. The study was conducted on 520 hospital workers who use cosmeceutical cosmetics in hospitals (dermatology, plastic surgery, women's clinic, and other hospitals) in Seoul, Gyeonggi and Incheon. A total of 502 questionnaires were used for the final analysis. The data analysis consisted of Cronbach's alpha, one-way ANOVA, exploratory factor analysis and Duncan test. Correlation analysis was performed to investigate the correlation between variables, and regression analysis was conducted to test hypotheses. The study results revealed that when choosing cosmetic cosmetics, marketing communication is influential. Especially, product value, quality, and price factors strongly affect marketing communication. This shows that we value the product and quality the most and we want a reasonable price. Considering this, we will pursue differentiated products only from cosmeceutical cosmetics and provide them as basic data necessary for securing potential customers and increasing the sales of cosmeceutical cosmetics in accordance with the changing trends.

BACKGROUND/OBJECTIVES: Korea is quickly becoming an aged society. Dementia is also becoming a vital public health problem in Korea. Cognitive impairment as a pre-stage of dementia shares most risk factors for dementia. The aim of the present study was to determine associations of serum levels of vitamins A, C, and E with the risk of cognitive impairment among elderly Koreans. SUBJECTS/METHODS: In this cross-sectional study, a total of 230 participants aged 60-79 years from Yangpyeong cohort were included. Cognitive function was assessed by the Korean version of the Mini-Mental State Examination for Dementia Screening. The logistic multivariable regression model was applied to determine the effect of serum vitamins A, C, and E on the risk of cognitive impairment. RESULTS: There was no significant association between the risk of cognitive impairment and serum levels of vitamin A and vitamin C. There was a significant odd ratio when the second tertile group of beta-gamma tocopherol level was compared to the first tertile group [odds ratio (OR) = 0.37, 95% confidence interval (CI) = 0.14-0.98, P for trend = 0.051]. In subgroup analyses, there were significant negative associations between beta-gamma tocopherol level and the risk of cognitive impairment in men (OR = 0.17, 95% CI = 0.03-0.87, P for trend = 0.028), non-drinkers or former drinkers (OR = 0.13, 95% CI = 0.02-0.66, P for trend = 0.025), and non-smokers or former smokers (OR = 0.27, 95% CI = 0.09-0.82, P for trend = 0.017). CONCLUSION: Serum beta-gamma tocopherol levels tended to be inversely associated with the risk of cognitive impairment. Further prospective large-scaled studies are needed to examine this association.

The purpose of this study was to investigated the effects of alcohol intake on blood pressure, serum lipids, liver function tests and obesity indices in middle-aged male workers. The 2,175 male workers aged 30-59 years who examined health checkup were recruited as the study subjects during the period between January to December, 2013. We observed the relationships between the amount of alcohol intake and blood pressure, serum lipids, liver function tests and obesity indices. As a result, the mean score of SBP, DBP, LDL-C and TG were significantly higher increasing with amount of alcohol increased, but HDL-C were significantly lower increasing with amount of alcohol increased. AST, ALT, ALP and ${\gamma}$-GTP were significantly higher increasing with amount of alcohol increased, but obesity indices were not significant. Age adjusted odds ratios(ORs) increasing with abnormal levels of SBP, DBP, HDL-C, LDL-C, TG, AST and ALT were significantly increased in heavy drinking group than light drinking group. Above results suggested that the heavy drink related with blood, serum lipid levels and liver function test levels, but not find out with obesity indices.

The purpose of this study was to analyze a change in Post-traumatic Stress Disorder (PTSD) level and the continuity of the effects in music therapy by applying short-term music therapy program in fire fighters with Post-traumatic Stress (PTS). Forty two fire fighters in 3 districts were randomly assigned to experimental group (21 subjects) and control group (21 subjects). Music therapy was applied in totally 10 sessions by two sessions (120 minutes) a day for 5 days. PTS level was measured immediately after the end of program, after 4 weeks, and after 12 weeks. As a result, PTS level has significantly decreased into $8.90{\pm}4.55$ from $26.52{\pm}2.32$ right after the music therapy program(p<0.05). And the effect was shown to be continued significantly up to after 4 weeks($11.95{\pm}4.57$) and after 12 weeks($13.76{\pm}5.62$)(p<0.05). As a result of research, it is considered that the music therapy is effective approach for reduction in PTS as for fire fighters who belong to the group with high risk of PTSD. Accordingly, the application of regular program for managing fire fighters' mental health is understood to likely to contribute to enhancing the field service competence.

Vanilloid receptor, TRPV1 (transient receptor potential vanilloid 1) is a non-selective cation channel that responds to a variety of pain-eliciting material including capsaicin, pH, heat. Although, membrane trafficking of TRPV1 was not much known so far, TRPV1 was reported to interact with FIP3 (family of Rab11 interacting protein 3). FIP3 was identified as one of Rab11 interacting proteins that is recently reported important in membrane trafficking of several channel proteins directly or indirectly. Therefore, in this study, we examined the role of Rab11 in the membrane trafficking of TRPV1 using cell biological and biochemical techniques. Rab11 was found really colocalized with TRPV1 based on the result of confocal microscopy. However, GST-pulldown assay, one of biochemical technique, found that Rab11 did not interact with TRPV1. Although Rab11 does not interact with TRPV1 directly, we hypothesized that Rab11 is indeed involved in the membrane trafficking of TRPV1. In order to examine further the role of Rab11 in the membrane trafficking of TRPV1, the expression of TRPV1 on the membrane was examined when the expression of Rab11 was decreased down to about 50% by siRNA technique and found decreased significantly. From this result, we can conclude that Rab11 is involved in the membrane trafficking of TRPV1 in a way of including FIP3.

The present study was to elucidate such a relationship by comparing the coronary risk factors with and without fatty liver adjusted for age and/or BMI. Study subjects were 665 women of 30 years and over, who underwent health package check-up at the health promotion center of an university hospital from July, 2009 to June, 2010. As a results, the prevalence rates of fatty liver of study subjects were 11.6%, and the rates were significantly higher in older age group, in the group of higher level of BMI. The group of subjects with fatty liver had significantly lower mean HDL-cholesterol and higher levels of body fat rate, TG, TC, LDL-cholesterol, FBS and ALT, then those parameters in subjects without fatty liver, even after adjustment for age and/or BMI. In age and BMI adjusted logistic regressions, The odds ratio of fatty liver was increased significantly as there is an increase in the abnormal group with TG, TC, LDL-C and ALT.

This study was conducted to determine the quality of sleep, and its association with the sociodemographic characteristics, health-related characteristics, and job-related characteristics among male workers in small-scale manufacturing industries with fewer than 50 members. A self-administered questionnaire was distributed to 856 male workers from April $1^{st}$ to June $30^{th}$, 2011. The survey items included the variables of sociodemographic, health-related, job-related, and quality of sleep. As a result, the quality of sleep according to the PSQI of the study subjects revealed 32.0% to be good and 68.0% to be poor. The quality of sleep assessed by hierarchical multiple regression analysis was significantly lower in the married group, those with lower BMI, and those with a lower level of subjective health status, non-smoking, alcohol drinking, without regular exercise, coffee drinking, blue color, had a longer of working hours, subjective health status, had a visiting out-patient department, and had a history of hospitalization. With the above model, the job characteristics had 13.1% explanatory power. This suggests that the quality of sleep (PSQI) has more power when combined with the job characteristics.

This study attempted to examine the relationship between pygmalion leadership and the organizational commitment among hospital employees, and the mediating effect of the leader-member exchange (LMX) on their relationship. For this purpose, we designed structured self-response survey questionnaires, and collected data from 349 employees working at 9 hospitals and ambulatory clinics in Busan area. Frequency analysis, correlation analysis, factor analysis, and reliability analysis were performed using SPSS ver.18.0 program, and the path analysis was performed using AMOS ver.18.0 program. Major findings are as follows. First, some factors of pygmalion leadership were found to directly influence the quality of LMX, while some had both direct and indirect influences on organizational commitment. Second, the quality of LMX was found to partly mediate the relationship between pygmalion leadership and the organizational commitment in hospital organizations. This is the first in kind which was conducted in the hospital setting.

The present study was intended to reveal the relationships between serum lipid levels and various factors of obesity and blood pressure. The study subjects were 1,838 adult women measured at a mass health screening during the period from January through December, 2011. TC, TG, HDL-C, LDL-C, SBP, DBP, degree of obesity, body fat rate were measured and the relation between these obesity and blood pressure measurements to serum lipid levels were studied. As a results, TC, TG, LDL-C, body fat rate and degree of obesity increased linearly with advancing age. TC, TG and LDL-C increased linearly with increasing blood pressure, and these values were higher in hypertension group than that of normal group. TC, TG and SBP increased linearly with increasing degree of obesity, and these values were higher in obesity group than that of normal group. HDL-C decreased linearly with increasing degree of obesity, and these values were lower in obesity group than that of normal group. TC, TG, HDL-C, degree of obesity, body fat rate was positive correlation with each others, but these values negatively correlated to HDL-C. Principal component analysis, showed that subjects could be divided into the group having the hypertensive group(1st principal component), the obesity group(2nd principal component), the hyperlipidemia group(3rd principal component), and HDL-C(4th principal component). In multiple regression analysis, age, TC, TG and body fat rate were affected to HDL-C. Above results suggest that higher the degree of obesity and blood pressure, the higher the serum lipid levels.
