This study aimed to identify the effects of lifestyle on Mibyeong, and provide basic data for health promotion activities for management of Mibyeong. A total of 405 data were analyzed for Daejeon University employees from July, 2015 to Jan, 2016. In this study, we collected the data about sex, age, BMI, dietary habit, physical activity, smoking, drinking, and Mibyeong index. There was a difference between Mibyeong groups according to irregular eating, eating of night snack, and smoking for men, while overeating, irregular eating, and physical activity for women. Logistics regression analysis, adjusting for sex and age, was used to estimate related factors of Mibyeong. Compared to the healthy group, Mibyeong 2 group tended to overeat 4 times a week with odds ratio of 3.52, eat irregularly with odds ratio of 2.67, lack of physical activity with odds ratio of 3.30, and to smoke with odds ratio of 3.07. This study suggests that lifestyle, particularly dietary habit, physical activities, and smoking, might be significantly associated with Mibyeong. Good lifestyle could help prevent Mibyeong.

Objectives: This article reviewed research on smoking behaviors and smoking-related health problems among university students to suggest evidences for developing smoking control strategies for them. Methods: Domestic research papers were screened through Research Information Sharing Service (RISS), Koreanstudies Information Service System (KISS), Medical Library Information System (MEDLIS), Korean Medical Database (KMbase), and digital national assembly library. International papers were searched mainly via PubMed. Results: Smoking prevalence among male college students were found to be over 50% in majority of Korean studies. While studies on smoking-related health problems were scant in Korea, several recent studies overseas showed possible effects of smoking on health among young adults, including decreased lung function, respiratory symptoms, cardiovascular problems, glucose intolerance, buccal disease, depressive symptoms, and so forth. Besides, smoking behaviors were closely related with other risk behaviors including drinking, and several psychosocial factors. Conclusions: To explore the smoking problem among college students, the first step should be a national representative survey with scientific methods. More research should be focused on the smoking-related problems among college students. To prevent smoking among college students, smoking prevention education, and smoking cessation counseling, and the initiatives of smoke free campus are needed.

Purpose:The present qualitative study explored adolescents' perceptions regarding effective strategies to prevent adolescents from using tobacco products (TP). Apart from the commercial TPs, there has been emerging use of alternatives such as vapes, e-cigarettes and shisha. This unfortunate phenomenon continues despite the currently available preventive strategies. Thus, understanding of the perceptions of the current generation would be valuable to provide new insights. Methods: Purposive sampling was utilized to recruit 40 adolescents between the age of 15 and 16 years old attending public daily secondary schools. Eight focus group discussions were conducted among the TP users, ex-users and non-users. Data were analyzed using a thematic content analysis procedure with NVivo. Results: Among barriers with the currently available strategies were having teachers who smoke tobacco, addiction to nicotine and self-perceptions of being healthy. The content of any program should include knowledge on negative outcomes of using tobacco products and awareness of the legislation together with ways to overcome peer and family influence including improving self-efficacy and refusal skills. Strategies were suggested to be delivered using information technology which provides interactive learning and visual effects. Conclusions: Adolescents agreed that the content and delivery of tobacco use prevention strategies need to be revised to suit the current generation to ensure sustainability.

Ventilation fans utilized correctly can increase the effectiveness of fire fighters and survivability of occupants. It is possible to increase the pressure of a corridor to prevent the infiltration of smoke. In this study, experiments were carried out to evaluate ventilation effectiveness in corridor fires. Corridor used in the experiment was 20 m long. Heptane was used as a fuel. Temperature and visibility were measured in order to evaluate ventilation effectiveness according to the position of a vent. Vent distance ranged from 0 m to 4 m and height varied from 0 m to 1.5 m. When the vent was positioned 2 m long and 0.75 m high the result was most effective.

Purpose: To assess the health status and health behavior characteristics of immigrant women married to Koreans. Method: A descriptive research design was employed. Fifty female marriage immigrants who were clients of the visiting health program at W public health center were recruited. After full consent, direct interview with a structured questionnaire and physical measurements were conducted by visiting health nurses. Descriptive statistics were utilized. Results: All of the subjects showed normal blood sugar. 25.7% of them exhibited extreme body weight condition of either obesity or low body weight by BMI. 36.4% had pre-hypertension stage and 15.9% had first stage of hypertension. Only two of the women had been diagnosed with hypertension and treated by a doctor. Almost all (95%) of them perceived their general health status as good or moderate. Most of them did not exercise, smoke or drink. Regarding dental care, no subject brushed before lunch. and only one did between meals. About 30$\sim$60% of subjects had undergone health screening. Conclusion: Health education is needed for immigrant women married to Koreans to enhance their health behavior, prevent life style disease and improve their health.

Significant portion of the fire accident is caused by some troubles in electric circuits. To prevent the fire induced by those electric trouble, some indications of electric fire need to be suitably detected at the first stage of the fire development. With this background, the characteristics of soot yielding of electric cables have been investigated using a light extinction method. In this study, a light scattering method was compared with the light extinction method. A slot-type premixed-flame combustor was traversed to bum three types of electric cables by compulsion, then the mass decrease rate and the soot densities were measured. According to the experimental results, the light scattering method is preferred to the light extinction method when the soot yield ratio is relatively small. Thus the former method is more suitable to detect the occurrence of an electric fire in a power distributer box.

Nicotine is one of the major hazardous components in cigarettc smoke. Nicotine deals a harmful effect to smokers and passive smokers due to its rapid conversion to various carcinogenic metabolites. Nitrosamine-4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is believed to cause lung cancers among the nicotine-derived carcinogens. Recent studies report that NNK synthesis can be inhibited by the metabolism pathway to produce a stable metabolite cotinine from nicotine. Tea polyphenols have been known to contain factors to prevent cancers and to retard progression of cancers. This study aims to correlate tea polyphenol's potential for cancer prevention with an accelerated formation of cotinine. The conversion from nicotine to cotinine in the presence of tea extracts or three polyphenols (Catechin, epicatechin gallate, epigallocatechin gallate) was measured in established cell lines and in Xenopus oocytes. Among three lines of cell used, PLC/PRF5 and HEK293 cells showed a fast turnover from nicotine to cotinine while HepG2 cell line showed a marginal difference between groups treated and non-treated with tea polyphenols. When Xenopus oocytes were microinjected with nicotine, tea polyphenols appear to accelerate the conversion of nicotine to cotinine. Among the polyphenols tested in this study, (＋)－catechin showed the best efficiency overall in accelerating conversion from nicotine to cotinine both in the cell lines and in the oocytes. In summary, the present study indicated that tea polyphenols have a positive effect on conversion of nicotine to cotinine.

Large fires continue to spread throughout the building, including the fire in Uijeongbu in 2015, the fire in Jecheon in 2017, and the fire in Miryang in 2018. According to the above fire case investigation, major problems were the fire resistance performance of compartment members such as fire doors, the fire spread due to damage to exterior wall openings, and smoke spread through vertical openings. However, in South Korea, only specification design is implemented for buildings that are not subject to performance design. In addition, the analysis of the fire resistance performance standards of building members in the specification design showed that fire doors were not specified in detail for 60 minutes of insulation performance and 60 minutes of fire resistance performance of E/V doors, limiting the prevention of fire spread. Therefore, the purpose of this research is to prepare measures to prevent the spread of fire by presenting simple transplants for calculating the required fire time according to the architectural design conditions for the performance design of the components of the fire room according to the purpose of use of the front of the building.
