The purpose of this study was to examine whether senior simulation would bring any positive change to the attitude of dental hygiene students toward the elderly. The experimental group consisted of 58 dental hygiene students at a college. The experimental procedure was to do activities for 40 minutes wearing aging simulation suit. Self administered questionnaires were used to ask the attitude toward the elderly after senior simulation. The data were analyzed with SPSS program. General and aging related characteristics of subjects were analyzed through descriptive statistics. To testify the differences of the attitude after senior simulation, paired t-test was used. An experiment was conducted from May 27 to June 14, 2012, and the findings of the study were as follows: 1. There wasn't any perfect positive change in the overall attitude of the students toward elderly people after senior simulation, but their attitude got a little more positive whereas they took a neutral attitude in the past; 2. The students who had ever lived with elderly people under the same roof and who had ever received education related to the elderly underwent a more positive change in their attitude toward the elderly; 3. To what extent senior simulation was helpful for the understanding of the elderly was checked, and the majority replied that it was very useful or useful for the understanding of their physical aspects. The findings of the study confirmed that senior simulation didn't change the overall attitude of the students toward the elderly in a positive way yet brought about some positive changes in part. Therefore senior simulation is expected to be one of significant educational programs that could encourage students to have a better physical understanding of the elderly, to take a more positive attitude to them and to provide them with quality dental service.

Background: Hepatic steatosis measured with controlled attenuation parameter (CAP) using transient elastography predicts metabolic syndrome in the general population. We investigated whether CAP predicted metabolic syndrome in chronic kidney disease patients. Methods: CAP was measured with transient elastography in 465 predialysis chronic kidney disease patients (mean age, 57.5 years). Results: The median CAP value was 239 (202-274) dB/m. In 195 (41.9%) patients with metabolic syndrome, diabetes mellitus was more prevalent (105 [53.8%] vs. 71 [26.3%], P < 0.001), with significantly increased urine albumin-to-creatinine ratio (184 [38-706] vs. 56 [16-408] mg/g Cr, P = 0.003), high sensitivity C-reactive protein levels (5.4 [1.4-28.2] vs. 1.7 [0.6-9.9] mg/L, P < 0.001), and CAP (248 [210-302] vs. 226 [196-259] dB/m, P < 0.001). In multiple linear regression analysis, CAP was independently related to body mass index (${\beta}=0.742$, P < 0.001), triglyceride levels (${\beta}=2.034$, P < 0.001), estimated glomerular filtration rate (${\beta}=0.316$, P = 0.001), serum albumin (${\beta}=1.386$, P < 0.001), alanine aminotransferase (${\beta}=0.064$, P = 0.029), and total bilirubin (${\beta}=-0.881$, P = 0.009). In multiple logistic regression analysis, increased CAP was independently associated with increased metabolic syndrome risk (per 10 dB/m increase; odds ratio, 1.093; 95% confidence interval, 1.009-1.183; P = 0.029) even after adjusting for multiple confounding factors. Conclusion: Increased CAP measured with transient elastography significantly correlated with and could predict increased metabolic syndrome risk in chronic kidney disease patients.

Purpose: Obesity and headache are two highly prevalent diseases both in childhood and adolescent. In this study, we assessed the prevalence of obesity in pediatric headaches patients in a single institution in Korea, and differences according to age, sex, headache type, frequency, intensity, and disability. Methods: We retrospectively reviewed the medical records of 340 subjects (6-18 years of age) who visited the Pediatric Headache Clinic of Bucheon St. Mary's Hospital during the period from January 2015 through March 2018. Data on age, sex, height and weight, as well as headache type, frequency, intensity and disability, were collected. Body Mass Index (BMI) percentile was calculated based on the 2017 Korean Children Adolescence Growth Chart. Results: 17.6% of the pediatric headache patients were obese. The prevalence of obesity in male patients was higher than females (Male 23.8% VS Female 11.6%, P=0.002). There were no significant differences in obesity rate according to age, headache type, frequency, intensity, and disability. Conclusion: The prevalence of obesity in the pediatric headache population was 17.6% which is higher than 10.1% in general population (Korea National Health and Nutrition Examination Survey, KNHANES, 2013).

This study attempts to explain how depression among community elderly relate to suicidal ideation and whether or not the psycho-social characteristics of elderly persons moderate the relationship between these two variables. This study was conducted in Seoul, Busan, and Daegu and included 273 persons 65 years and above who were using senior welfare centers in the communities. For the questionnaire and analysis, this research uses the Health Care, Life Event, Self-esteem, Family Assessment scales. This research utilizes a wide range of statistical analyses, such as descriptive analysis, Pearson's correlation, reliability analysis, multiple regression, and general linear modeling. The calculations employed the use of SPSS/PC+ 12.0. This research indicates, among other things, that elderly persons with a high level of depression and psycho-social characteristics show a tendency toward higher suicidal ideation and that the level of self-esteem, life event, and family communication plays a moderating role in the relationship between depression and suicidal ideation among community elderly. In conclusion, elderly persons who experienced with a high level of psycho-social characteristics shows a relatively greater tendency toward suicidal ideation when compared to elderly persons having a low level of psycho-social characteristics. The intervention's effectiveness in reducing suicidal ideation can reinforce self-esteem, and cope with stressful life events and family discord as prevention strategy to reduce risk factors for suicide in late life.

This study focuses on adolescent prosocial behavior as one of the necessary elements for youth to grow as a healthy member of the society. The purpose of this study is to examine the effects of peer group on adolescent prosocial behavior by comparing the peer influence model and the individual characteristics model. For the study, we conducted hierarchical multiple regression analyses using the data from the Korean Youth General Survey 2008, administered by the Ministry of Health and Welfare. Results show that friends' prosocial behavior had a positive impact, but friends' antisocial behavior had a negative impact on adolescent prosocial behavior. When individual characteristics including self-esteem and empathy were analyzed simultaneously, empathy, self-esteem, friends' prosocial behavior, and friends' antisocial behavior were found to be statistically significant. The strength of association between individual characteristics and adolescent prosocial behavior was greater than that of friends' behaviors. Also, significant moderating effects of individual characteristics on the relationships between adolescent prosocial behavior and friends' behaviors were found. For example, the positive effect of friends' prosocial behavior on adolescent prosocial behavior increased as adolescent's level of self-esteem increased. On the other hand, the negative effect of friends' antisocial behavior on adolescent prosocial behavior decreased as adolescent's level of empathy increased. Based on the findings, both the peer influence model and the individual characteristics model were considered valid in explaining prosocial behavior of Korean adolescents. Finally, implications of this study for positive youth development were discussed.

This study is about the cosmeceutical products using enzyme induced bio-conversion system. In general, ascorbic acid (AA) has the higher reducing activity and can be used for various purpose in the cosmetics. But it is very unstable in the aqueous system and difficult to maintain its stability in the cosmetics product. 2-O-$\alpha$-D-Glucopyranosyl-L-ascorbic acid (AA2G) is the stabilized form of AA and showed the less whitening activity than AA. In this study, we developed bio-conversion system improving the stability and efficacy of AA2G and AA, respectively. In this system, AA2G (over $80\%$) can be converted to AA and glucose within 30 min. The converted product showed higher anti-tyrosinase activity like AA (AA2G showed no anti tyrosinase activity) and depigmenting activity in the artificial tanning test. From these results, we could conclude this system is a brand new method to increase the activity of AA and maintain its stability.

At the current situation of continuous utilization of heavy metal contaminated upland for agricultural purpose in Korea, minimizing transport of heavy metals from soil to crops is important for securing safety of human health. The present study (in field scale) examined the efficiency of several soil amendments (dolomite, steel slag, lime, zeolite, and compost) on reduction of phytoavailable heavy metals (Cd, Cu, Pb, and Zn) in soil through comparison with no amendment treatment and clean soil cover treatment. For determination of the phytoavailability, 1 M $NH_4NO_3$ extraction and red pepper cultivation were introduced. Among the amendments, in general, dolomite and steel slag were the most effective in reduction of metal (Cd, Pb, and Zn) phytoavailability resulting in less accumulation of these metals in shoot and fruit of red pepper. However, dolomite and steel slag treatment was not as effective as clean soil cover treatment which showed the least metal accumulation in red pepper fruit. Nevertheless, with taking into account the cost, treatment of dolomite or steel slag can be competitive method because the current study showed that dolomite or steel slag treatment reduced accumulated heavy metal concentration effectively in both shoot and fruit of red pepper compared to those from control soil and the concentration in fruit was within the standard value (<0.2 mg $kg^{-1}$ for both Cd and Pb).
