This study was conducted to investigate the drinking status, drinking habit and dietary habit of high school students using anonymous questionnaires. DVS and skipped meal status were obtained by 24 hour recall method. Two hundreds ninety seven of 380 students (78.2%) have experienced the drinking even though 73.7% of them was not addictive. One hundred sixty one students (54.2%) initiated drinking in the middle school, mostly because of ‘peer pressure’ and ‘curiosity’. The most plausible reasons for drinking were ‘for mingling’ and ‘for stress reduction’, and they used to have desire for drinking mostly when felt ‘anger or frustration’ and ‘feel good’. Drinking behavior was significantly different in age of first smoking, drinking history, amount, reason for drinking and desire for drinking between male and female student. There was no significant difference in dietary habits between drinking students and non-drinking students. DVS, skipped meal status, snack preferences and food intake frequency also did not show the significant differences. However, considering that the drinking experience of high school students increased, and drinking experience of female students approached to that of male student, more attention needs to be given to juvenile drinking and its'prevention.

Objectives: It is known that the majority of middle schoolers spend the substantial amount of time using the Internet. Despite the fact, little is known about which factors are related to an increase in Internet use and what could be the consequences of excessive Internet use. The aim of this study was to explore factors affecting an increase in Internet use among elementary schoolers representing the population of South Korean elementary schoolers. Method: Secondary data obtained from the Korea Youth Panel Survey were analyzed longitudinally. Results: The average minutes spent using the Internet was 73.43 in the first wave, and was 92.17 in the second wave. Also, the percentage of those who experienced illegal behaviors on the Internet was 22.86% in the first wave, and was 30.92% in the second wave. Second, increased Internet use was strongly associated with an attack tendency, depression, suicidal ideation, stress, and delinquent behaviors. Finally, gender(being female), and increased attacking tendency, and smoking experiences successfully predicted an increase in Internet use one year later. Conclusions: It is necessary to provide education programs to young people and to develop preventive strategies for them. Through providing education programs, children can form desirable attitudes regarding the Internet use. Through providing intervention strategies, children can prevent from experiencing negative consequences due to excessive Internet use.

This study aimed to investigate the relationships between depressed mood and life style patterns, including smoking, alcohol drinking, and physical inactivity in Koreans aged 40 years, which is a critical life transition period. Based on the Life Transition Period Health Examination at the Korea Association of Health Promotion conducted in 2011 (n=27,684), participants were categorized into a depressed mood group and a non-depressed mood group based on the results of the Primary Mental Health Questionnaire. The depressed mood group showed higher tendency for smoking compared to the non-depressed mood group. Current and ex-smokers were about twice as likely to have a depressed mood as the non-smokers. The prevalence of nicotine dependency was significantly higher in the depressed mood group. The number of days and amount of alcohol consumption were significantly correlated with depressed mood. The prevalence of alcohol dependence and alcohol abuse was higher in the depressed mood group than in the non-depressed mood group. The frequency of high-intensity exercise per week was negatively correlated with the number of people with a depressed mood. This study showed the significant relationships between depressed mood and smoking, alcohol drinking, and physical activity in adults during an important life transition period. This implies that the development of proper lifestyle intervention or education may be needed to prevent depressed moods in this age group.

Introduction: Although it is well known that medical students are not getting an adequate amount of sleep, there have been only few studies on the sleep patterns of medical students in Korea. Therefore, the present study aimed to investigate the life style and sleep patterns of Korean medical students and the impact they have on the students' academic performance. Methods: A questionnaire package was administered to the $3^{rd}$ year medical students at the Seoul National University to examine their sleep patterns on weekdays and weekends. It consisted of questions asking about their lifestyles as well as Pittsburgh sleep quality index (PSQI) and GPA (Grade Point Average) that are considered relevant to their sleep patterns. A total of 110 students (85 males and 25 females, mean age $24.4{\pm}20.6$) responded to the survey and the result was analyzed using the independent t-test, the chi-square test, the paired t-test, Pearson's rank correlation and ANOVA. P-values of less than 0.05 were considered statistically significant in all analyses. Results: The weekend bedtime was significantly delayed (01：24 on weekday；03：12 on weekend; t=-5.23, p<0.01), the weekend rise time was delayed (07：36 on weekday；10：30 on weekend ; t=-24.48, p<0.01) and the total sleep time was increased on weekends (5：57 on weekday；8：17 on weekend ; t=15.94, p<0.01). They wished to sleep for 7 hours 6 minutes which was different from their actual weekday total sleep time (t=-11.41, p<0.01). The poor sleeper group had lower GPAs than the good sleeper group (t=2.05, p<0.05). The GPA of medical students were negatively correlated with age (r=-0.23, p<0.05), daily amount of smoking (r=-0.78, p<0.01), total amount of smoking (r=-0.75, p<0.01), weekday sleep latency (r=-0.23, p<0.05), weekend sleep latency (r=-0.23, p<0.05) and PSQI score (r=-0.30, p<0.01). Conclusion: Medical students were experiencing a lack of sleep during weekdays as they have a later bedtime and earlier rise time, and consequently had more hours of sleep on weekends. Overall, the responded students were experiencing poor sleep quality, and the GPAs of the poor sleeper group were lower than those of the good sleeper group.

This study investigated to changes in the sensory characteristics of cheonggukjang made with smoked soybean. The total organic acid content of cheonggukjang made with smoked soybeans (CSS) increased to about two times in comparison with cheonggukjang made with non-smoked soybeans (CNS). Among the organic acids, the amount of succinic acid was highest for both CSS and CNS. The total free sugar content of CSS ($228.6{\pm}8.8mg%$) was significantly reduced compared to that of CNS ($350.1{\pm}13.7mg%$). Further, the total free amino acid content of CSS ($10,123.3{\pm}301.4mg%$) was significantly increased compared to that of CNS ($8,912.5{\pm}286.5mg%$). The contents of sweet, savory and bitter taste compounds were significantly elevated in CSS when compared to that of CNS. However, there were no significant differences in the total content of fatty acids in CNS and CSS. The sensory evaluation of aroma, taste and overall quality of CSS were significantly increased compared to that of CNS. Taken together, it was expected that a smoking process is useful for the development of new fermented foods.

The purpose of this study is to investigate the effect of social factors and social stress with respect to alcohol consumption for university students and to provide basic data in efforts to develop educational method that teaches how to decrease alcohol consumption and deny demanding drinking. Questions concerning typical features and social stress from drinking were revised through 300 university students' self-recording surveys between April 8 and 9 in 2015. It consisted of 10 questions using a 4-point Likert scale. Moreover, the reliability of tool was Cronbach ${\alpha}=.82$. We used SPSS 18.0 and conducted frequency, ${\chi}^2$ and path analysis. If the frequency of drinking (B=.206, p<.001) gets low and the social stress from drinking is low (B=-.397, p<.001), the amount of drinking increases, particularly for men more than women (B=.169, p<.05). For women more than men (B=.274, p<.01), if monthly income is high (B=.178, p<.05) and stress from drinking is low (B=-.349, p<.01), the frequency of drinking is high. If the culture of practice in drinking has not formed voluntarily through education or publication, legal restriction that increases the cost of drinking has to be established, like smoking, to reduce the volume of drinking and promote moderation in drinking. The publication and education that teaches drinking leads to bad situations have to be conducted, much like the education programs involved for smoking. Also, discrimination of non-drinker has to be removed with the change of culture to reduce the stress by drinking.

Most electric rooms are located in the underground spaces of buildings. When a fire occurs in electrical equipment, the fire expands to cable insulation material, resulting in toxic smoke and combustion products. If the smoke and combustion products quickly move vertically and horizontally, the evacuation of occupants and firefighting activities will be hindered. Therefore, it is necessary to design optimal equipment for smoke control in cases of fires in electric rooms. This study analyzes the characteristics of smoke and combustion products in fires in a cubicle-type switchboard in an electric room using PyroSim, which is based on the program Fire Dynamics Simulator (FDS). The fire modeling consists of four scenarios according to the operation mode of the mechanical ventilation equipment, the amount of air supply and exhaust, and the location of the air supply slot. The analysis shows that the mechanical ventilation equipment improves the smoke density, visibility, carbon monoxide concentration, and temperature characteristics. The visibility and temperature characteristics were improved when the air flow rate and the location of the air supply slot from fire defense regulations were applied.
