Scientific evidence on all aspects of smoking amongst youth is very important for designing appropriate interventions to reduce smoking among this vulnerable population. This paper describes current access to anti-smoking information among school children aged 13 to 15 years in Vietnam in 2014 and examines its potential impact on preventing smoking initiation. The data used in this paper were obtained from the 2014 Global Youth Tobacco Survey (GYTS) in Vietnam. Students were asked questions about their level of awareness of anti-smoking information from various sources in the past 30 days and about lessons in school regarding the dangers of tobacco use during the last 12 months. Those who have never smoked were asked "whether or not they thought about avoiding cigarettes because of health warnings on cigarette packages" and answers were analyzed in combination with data on access to anti-smoking information from other sources. The prevalence of exposure to antismoking campaigns was high among school children in Viet Nam: 55.3% of current smokers reported thoughts of smoking cessation because of health warnings on cigarette packages; 60.5% of never smokers avoided initiating smoking because of the same health warnings. The potential impact of graphic health warnings to prevent school-aged children from smoking initiation would be stronger if there was concurrent access to anti-smoking programs on the dangers of tobacco use in schools. However, school education for tobacco prevention and control has not been as strong as expected. A more comprehensive school curriculum on tobacco prevention and control is recommended to reinforce antismoking messages among school children.

With recent development in information technology, IT convergence has been achieved ubiquitously in all areas of industry. In particular, there have been a lot of changes in medical IT conversion sector in terms of user service. In this regard, this paper attempts to propose an environment in which the existing paper prescription can be transferred in the form of QR codes using mobile handsets as one of practices from the perspective of user service. QR codes can minimize the burden resulting from the process of the output, delivery and storage of paper prescriptions. In addition, they can utilize the representation of the information in a wide variety of ways, and they are considered to be media that can minimize the risk of personal information exposure and falsification due to the restoration and encryption of the information. Accordingly, the application of QR codes to the medical field is expected to improve confidentiality ad storage capability of the information, along with users' convenience.

Many child actors have appeared in various movies as the Korean film industry continues to evolve. As more children appear in violent and raunchy scenes, there are more concerns about the movie's effect on child actors. In some Western countries, many strategies have been developed for child actors, but for the Korean movie industry, the conditions are still poor for them. Although children who enter the concrete operational period are able to think logically and systematically, they are yet limited by their experiences. Adolescents in the formal operational period try to deal with all of the possibilities and assumptions logically and systematically with freedom from realistic contents and experiences. This period is very important because adolescents become more sensitive to others' feelings and they should develop their ego identity. Several studies have reported the indirect experiences through media including how the movie affected children and adolescents negatively. Depending on the individual's morality, judgment and emotional status, these effects were variable and inconsistent and could be relieved by several interventions. We could anticipate much bigger emotional effect on child actors who are acting directly and then are confronting themselves in the scene. Therefore, we suggest that the emotional effects of the movies on child actors can be managed properly by considering children's cognitive ability and emotional status, and establishing protective strategies before they are exposed to problematic scenes. Of course, it should be followed by evaluating them after the exposure and with follow-up management, if necessary.

Effects of hydrogen peroxide $(H_2O_2)-induced$ neurotoxicity were investigated in cultured newborn rat spinal dorsal root ganglion (DRG) neurons after DRG neurons were treated in the media containning various concentrations of $H_2O_2$. In addition, the protective effect of Herba Epimedii (HE) extract against $H_2O_2-induced$ neurotoxicity was examined. Cytotoxic values were determined by the cell viability of living cells using 3-(4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide (MTT) assay. In the present study, exposure of neurons to $H_2O_2$ resulted in a significant cell death in a dose- and time-dependent manners in cultured DRG neurons. The decrement of cell viability by $H_2O_2$ was blocked by HE. These results suggest that the neuroprotective effect of HE against $H_2O_2-induced$ cytotoxicity may result from the prevention of injury induced by $H_2O_2$.

Woman leadership has been remarkably highlighted with women's accelerating entry into society. Domestic and overseas interests about political leaders began with the age of media and they are rapidly spreading worldwide with the development of internet, SNS and blog. Along with this phenomenon, exposure of images has been remarkably increasing and fashion has been also used as a political strategy. However, the research on woman political leaders has been insufficient so this study selected Geunhye Park, Michelle Obama and Hillary Clinton as representative woman leaders for the research. 149 pictures of Geunhye Park, 171 pictures of Michelle Obama and 124 pictures of Hillary Clinton from the articles containing their pictures from Jan. 2002 to Dec. 2013 were analyzed, focusing on their gender. The three woman political leaders' typical images of femininity, masculinity and androgyny were categorized respectively and the period and works in which those images had been expressed were reviewed. Also, fashion styles of the images pursued by each gender were analyzed through their color, material, silhouette, design point, items and accessories. As a result, Geunhye Park had femininity image at the beginning and had masculinity image when she did election campaigns, which led to her current image of androgyny. Michelle Obama uses the image of femininity, masculinity and androgyny simultaneously. It was found that Hillary Clinton emphasized the image of masculinity and androgyny but she emphasizes femininity image these days.

Background: The rise in consumption of tobacco products among youth is a public health concern in India. Several studies have shown that advertisements promoting tobacco products influence decisions and behaviour of youth towards smoking. Objective: To ascertain which method of Tobacco Advertising, Promotion and Sponsorship (TAPS) was more influential for initiating tobacco use in youth in India. Materials and Methods: The secondary data of youth (15-24 years) from nationally representative Global Adult Tobacco Survey (GATS) conducted in 2009-2010 was analyzed. Odds ratio and p-value were used to know the association between TAPS and initiation of use of tobacco products among youth. Logistic regression was used to determine the most significant means of TAPS altering the youth's behaviour towards tobacco products. Results: Out of 13,383 youths, 1,982 (14.7%) used smokeless forms of tobacco and 860 (6.38%) used smoke forms. Logistic regression reveals that promotional activities mainly through cinemas (p<0.05) and providing free samples of tobacco products (p < = .001) were most influential means of initiating consumption of tobacco products among youth. Conclusions: The smoking in youth is associated with watching advertisements particularly in cinema and promotional activities like distribution of free samples, coupons and sales on the price of tobacco products. Stronger legislative measures should be enforced to curb promotional advertisements in cinemas and distribution of free samples.

To study the effects of Ramulus et Uncus Uncariae (REUU) on oxygen free radical-mediated damage by hydrogen peroxide $(H_{2}O_{2})$ on cultured spinal sensory neurons, in vitro assays such as MTT assay, NR assay, neurofilament enzymeimmuno assay (EIA), sulforhodamine B (SRB) assay, assay for lactate dehydrogenase (LDH) activity and assay for lipid peroxidation were used in cultured spinal dorsal root ganglion neurons derived from mice, Spinal dorsal root ganglion neurons were cultured in media containing various concentrations of $H_{2}O_{2}$ for 5 hours, after which the neurotoxic effect of $H_{2}O_{2}$ was measured by in vitro assay. The protective effect of the herb extract, Ramulus et Uncus Uncariae (REUU) against H2O2-induced neurotoxicity was also examined. The results are as follows. 1. In NR assay and MTT assay, $H_{2}O_{2}$ significantly decreased the cell viability of cultured mouse spinal dorsal root ganglion neurons according to exposure concentration in these cultures. An additional time course study was done on these cultures. 2. Cultured spinal dorsal root ganglion neurons which were exposed to various concentrations of $H_{2}O_{2}$ showed a quantitative decrease of neuronal cells by EIA and of total protein by sulforhodamine B (SRB) assay, while they showed an increase of both lipid peroxidation and LDH activity. 3. The effect of Ramulus et Uncus Uncariae (REUU) on $H_{2}O_{2}$ induced neurotoxicity showed a quantitative increase in both neurofilament and total protein, but showed a decrease of lipid peroxidation and LDH activity. These results suggest that $H_{2}O_{2}$ has a neurotoxic effect on cultured spinal dorsal root ganglion neurons from mice and that the herb extract, Ramulus et Uncus Uncariae (REUU), was very effective in protecting $H_{2}O_{2}$ induced neurotoxicity by decreasing lipid peroxidation and LDH activity.

Purpose : This study are the secondary data of Global Youth Tobacco Survey(GYTS) developed by the WHO and United State Center for Disease Control(CDC) and Prevention to trace tobacco use among youth in youth in countries across the world. This study was carried out to serve for a basis for antismoking campaigns and to prevent adolescents from smoking by analyzing the smoking by analyzing the smoking realities factors. Methods : This study is a cross-sectional school-based survey, which employed a two-stage cluster sample design to produce a nationally representative sample of middle school students aged 13 to 15 years olds. Seventy-five schools were selected. All schools containing grade 1, 2 and 3 that contained 40 or students were included in the sampling frame. Results : The results of this study were as follows ; 1. The proportion of smoking students in middle school was 6.4% and the rate of smoking in male students(7.4%) was higher than it of in female students(5.5%). 2. 26.5% of all respondent had a experience to try smoke and the results showed that the rate of trying smoking in male students was increased by grade more than female students. 3. According to test of significance in regression analysis, the independent variables such as sex, school grade, smoking parents, friends distinction, pocket money and others showed statistical significance. 4. There was a statistical significance between smokers and nonsmokers in proportion to the completing the preventive education for nonsmoking(p=0.0023) and the acquirement of knowledge on smoking(p<.0001). 5. Finally there was a statistical significance between the exposure to anti-smoking campaign(p=0.0053) and tobacco advertisement in the mass media and the smoking(p=0.0036). Conclusion : All things considered, the health education for tobacco control in school need to be developed from an elementary school. I suggest that prevent smoking program in school need to be revitalized and be made more accessible for everyone who wish to quit. And the government should develop the regulation on total banning promoting cigarette advertising and smoking scene in the movie for young people.

Sulfur dioxide discharged from the factories in Yeochun industrial complex severely damaged to the growth of oyster mushrooms. The continuous monitoring indicated that high concentration of sulfur dioxide was repeatedly detected in Kwang-Yang and Seung-Ju. The first injury symptoms on the mushroom fruit bodies were observed a day later when sulfur dioxide was detected over 300 ppb. Under the high concentration of sulfur dioxide exposure, the young fruit bodies showed blight and sudden death and the mature fruit bodies turned to blue-brown and frequently progressed to blight. The symptoms at Spring cropping were more severe than those at Autumn cropping. The severity was associated with the frequency of sulfur dioxide monitored. However, sulfur content in the mushroom fruit bodies and culture media did not show clear differences between the injured mushroom from Yeochun industrial complex areas and normal ones from no damaged areas.

Enzymes in organic media afford many advantages such as chiral synthesis and resolution, modification of fats and oils and production of biodegradable polymers. However, the nature of solvents influences the activity and stability of enzymes, and the presence of organic solvents always constitute a risk of enzyme inactivation. Heat-shock protein Hsp90, one of the molecular chaperone, was applied for understanding of enzyme inactivation and for increasing of enzyme stability in water-miscible organic solvent. Hsp90 showed stabilization effect on HRP in the 30％ of DMSO, in the 30％ and 50％ of dioxane. Hsp90 also showed reactivation effect on the inactivated HRP by water-miscible organic solvent such as dioxane and DMSO. In addition, structural analysis using fluorescence spectrophotometry and circular dichroism showed that exposure of HRP in water-miscible organic solvent caused appreciable conformational changes and enzyme inactivation, and the unfolded HRP by water-miscible organic solvent was refolded by Hsp90.
