In this study, the fire risk of the curtain wall structure was compared with a general structure among the double envelope structure using a fire simulation program. To this end, a fire-story building curtain wall was modeled as virtual using the PyroSim based on a fire simulation program (FDS). And then, the fires occurred in the model, divided by curtain wall non-applied model and applied model, in the same structure and place. To identify the fire characteristics, smoke behavior characteristics, viewing distance, and volume fractions of CO and $CO_2$ were comparative analyzed. As a result, it was identified that the curtain wall applied model quickly filled with smoke from the top floor to under the floor compared to the curtain wall non-applied model. From this study, the fire risk of curtain wall structure was evaluated in detail using the fire simulations.

This study was conducted to investigate the relationship between self efficacy and a health locus of control. We conveniently sampled 204 university students who smoke. We invastigated by using questionaries and collected data that were analyzed using a t - test, an analysis of variance, a Pearson product-moment correlation. The results are as follows: 1. The average score of self efficacy was 66.16 (out of a total score of 100.00) in university students who smoke. In relation to the health locus of control, the internality score was highest at 25.22, the influence of others was 20.39, and the effect of chance was 15.86. 2. In a significant test of the general character other and aspect related to the smoking of the subjects and in the score of the health locus of control, the internality score of subjects who had been never been asked to quit smoking was higher than that of subjects who had been. There are significant differences in the scores concerning the influence of powerful others, especially religion. In chance occurrences, the score of subjects in medical school was higher than in other schools. The lower the age one beginns smoking, the higher the score of chance. 3. In a significant test of the general character and other aspects related to smoking and the score of self efficacy, there was no significant relationship. 4. Considering the relation of self efficacy to a health locus of control, a positive relationship between self efficacy and internality, and the influence of others, but not between self efficacy and the effect of chance. With these results, we can conclude that the higher the level of self efficacy, the higher the internality, the higher the influence of powerful others. Consequently, it is necessary to identify the relationships clearly among self efficacy the health locus of control by repeated research. It can be used to support, revise and develop health behavior theory.

Background: Smoking is a learnt behavior during adolescence and understanding the factor/s associated with smoking will assist in identifying suitable measures in combating the rising prevalence of smoking among adolescents. This research aimed to identify the factor/s associated with smoking among form four students in Kota Tinggi, Johor. Multistage sampling was used to select a representative sample of students in 2008 and data were collected using a self-administered validated questionnaire. This study revealed that the overall smoking prevalence was 19.0% with a significantly higher proportion of male smokers (35.8%) as compared to females (3.15%). Adolescents who were male (aOR 6.6, 95%CI 2.61-16.4), those who had peer/s who smoked (aOR 4.03, 95% CI 1.31-12.4), and those who studied in rural areas and Felda Settlements ( aOR 4.59, 95 CI 1.11-18.0; aOR 9.42, 95%CI 3.91-29.1) were more likely to smoke in the past one week. On the other hand, adolescents with better knowledge on the hazards of smoking and negative attitudes towards smoking were less likely to smoke (aOR 0.51, 95%CI 0.37-0.72; aOR 0.67, 95%CI 0.46-0.99). Future promotional and interventional programmes on smoking should be considered and the above identified risk factors integrated to reduce smoking prevalence among students of school-going ages in Kota Tinggi.

Objectives: The purpose of this study is to find out differences in oral health status, defined as their oral health and oral health quality of life among the elderly depending on their income and education levels. Methods: This study used 922 senior citizens over 65 from the data (2015) of the 6th National Health and Nutrition Survey (NHNS). The regression analysis was adopted to identify factors affecting their oral health status which has effect on their oral health quality of life. The statistical package SPSS 21.0 was employed. Frequency analysis, chi-squared analysis and regression analysis were used, and the significance level or Cronbach's alpha value was 0.05. Results: Depending on income levels, there were differences in their oral health status as to whether they use oral hygiene products, take dental examinations, join private health-insurances, and delay dental treatments or not. And educational levels also made significant differences in their oral health status as to whether they smoke, drink alcohol, how many times they brush teeth a day, whether they use oral hygiene products, take dental treatments, and join private health-insurances. Regression analysis on the relationship between their oral health status and the oral health quality of life showed that there were significant differences depending on whether they take dental treatments, delay dental medical treatments, smoke, take oral examinations, how many times they brush teeth a day, and whether they use oral hygiene products, or join private health-insurances. Conclusions: The study shows that a comprehensive plan is needed to raise attention on proper oral health-care and ultimately to improve the quality of life by considering the daily number of tooth brushing, oral hygiene product use, regular dental treatments, and other medical uses.

Purpose : This study identified the patterns of smoking of students attending middle schools and high schools, and analyzed its related health risk behaviors. Methods: The data was based on the survey of 1,517 middle students and 911 high students residing in Kyung-Gi district. Results: The current smoking rates of male and female middle students are 5.3%, and 3.1% respectively. The rates of experiences in smoking are 21.4% and 16.0%(male/female). The current smoking rates of male and female high students are 17.9% and 8.5%, whereas the rates of experiences in smoking are 34.2% and 23.3% respectively. On the other hands, 14.1% of middle students and 12.0% of high students were exposed to smoking for at least 2 hours per day. The majority of middle and high school smokers started smoking when they were in middle or high school. And the most popular places to smoke were children's playgrounds, public open area., parks, and so on. Whether having a smoker as a friend or not and students' own perception towards smoking influenced the decisions to smoke for middle and high students. Both middle and high students, regardless of their gender, who have higher rates of drinking experiences and the hours of computer usage were found to have higher rates of smoking experiences. Meanwhile, the sleeping hours is in reverse proportion to the rate of smoking experiences. There was statistically significant difference in smoking experiences related to the degree of obesity only in the female high students: underweight and overweight students showed higher rates of smoking experiences than those falling in the normal weight range. Conclusion: For the effective prevention of adolescence smoking, it is necessary to adopt a comprehensive approach, which classifies the target population according to their age and sex and cover all health risk behaviors.

Streptococcus mutans 10449 was cultured in sucrose-containing BHI broth with ethyl alcohol of different concentration from 1% to 18%, The pH of culture media was from pH 7.00 to pH 5.00. Tobacco smoke and tobacco extract were also used. Ethyl acohol began to inhibit sucrose fermentation by S. mutans at 2% and completely inhibited it between 9% and 18%. The lower the pH of media was, the stronger the inhibition of ethyl alcohol became. 9% Ethyl alcohol completely inhibited sucrose fermentation by S. mutans below pH 5.50, Inhibition by tobacco extract was obvious, but it did not inhibit the growth of S. mutans also. Therefore, the increase of caries activity in drinkers and smokers could be the result of indirect effect of alcohol and tobacco by oral ecology, behavior, or systematic course, rather than the result of direct effect of alcohol and tobacco to plaque bacteria and their metabolism.
