In Vietnam, the WHO Framework Convention on Tobacco Control (WHO FCTC) took effect in March 2005 while MPOWER has been implemented since 2008. This paper describes the progress and challenges of implementation of the MPOWER package in Vietnam. We can report that, in term of monitoring, Vietnam is very active in the Global Tobacco Surveillance System, completing two rounds of the Global Adult Tobacco Survey (GATS) and three rounds of the Global Youth Tobacco Survey (GYTS). To protect people from tobacco smoke, Vietnam has issued and enforced a law requiring comprehensive smoking bans at workplaces and public places since 2013. Tobacco advertising and promotion are also prohibited with the exception of points of sale displays of tobacco products. Violations come in the form of promotion girls, corporate social responsibility activities from tobacco manufacturers and packages displayed by retail vendors. Vietnam is one of the 77 countries that require pictorial health warnings to be printed on cigarette packages to warn about the danger of tobacco and the warnings have been implemented effectively. Cigarette tax is 70% of factory price which is equal to less than 45% of retail price and much lower than the recommendation of WHO. However, Vietnam is one of the very few countries that require manufacturers and importers to make "compulsory contributions" at 1-2% of the factory price of cigarettes sold in Vietnam for the establishment of a Tobacco Control Fund (TCF). The TCF is being operated well. In 2015, 67 units of 63 provinces/cities, 22 ministries and political-social organizations and 6 hospitals received funding from TCF to implement a wide range of tobacco control activities. Cessation services have been starting with a a toll-free quit-line but need to be further strengthened. In conclusion, Vietnam has constantly put efforts into the tobacco control field with high commitment from the government, scientists and activists. Though several remarkable achievements have been gained, many challenges remain. To overcome those challenges, implementation strategies that take into account the contextual factors and social determinants of tobacco use in Vietnam are needed.

The purpose of this study was to identify convergence factors related to glycemic control in workers with diabetes mellitus. A secondary data analysis was conducted using the data of "The Korea National Health and Nutrition Examination Survey, 2009-2013." The survey included 44,085 adults aged over 19 under 65 years with diabetes mellitus and 764 samples with worker were used for this study. Data analysis was conducted using SPSS 18.0 program and descriptive statistics, Pearson's correlations, and multiple regression analyses were performed. The general characteristics variables shown statistically significant difference between the good and the poor glycemic control group was gender. The Health behavior-related and disease-related variables shown statistically significant difference between the good and the poor glycemic control group were diabetes mellitus duration, diabetes mellitus treatment, hypertension diagnosis, smoking, moderate physical activity, walking exercise practice. Factors related to glycemic control were gender, diabetes mellitus treatment, walking exercise practice. These findings suggest that researchers need more active treatment and walking exercise as important factors affecting glycemic control of Korean worker with diabetes mellitus and intervention focusing on the issues needs to be developed in workplace environment.

The long term success of periodontal treatment is dependent upon the effectiveness of the main-tenance care program after active treatment. The purpose of this study was to evaluate whether nutraceutical containing PRF-K2 as natural product from plant and seaweed has beneficial effects on clinical parameters, gingival crevicular fluid (GCF) volume and GCF cytokine levels during main- tenance phase after periodontal treatment. Among the generally healthy and non-smoking. moderate to severe chronic periodontitis patients during maintenance phase in Department of Periodontics, Chonnam National University Hospital, twenty eight patients took nutraceutical containing PRF-K2 (Oscotec Inc. Cheonan, Korea) for 3 months as experimental group and sixteen patients received only maintenance care as control group. Clinical examination and GCF collection were performed at baseline, 1, 2 and 3 months of experiment. Total amounts and concentrations of GCF IL-1{\beta}, IL-1ra and $PGE_2$ were evaluated using ELISA kit. In probing pocket depth, experimental group showed the tendency of more reduction than control group after 3 months of experiment. Sulcus bleeding index (SBI) and GCF volume were significantly decreased in experimental group(p<0.05), whereas they were increased in control group. GCF IL-1{\beta} level tended to decrease in both experimental and control group and IL-1ra concentration tended to increase in experimental group and to decrease in control group. IL-1ra/IL-1{\beta} ratio tended to increase in experimental group and to decrease in control group during experimental period. GCF $PGE_2$ amount did not show any change in experimental group and tended to increase in control group. These results suggest that nutraceutical supplement which contain PRF-K2 could improve perio-dontal condition during maintenance phase after periodontal therapy.

Objectives : This study was performed to investigate the distribution of apolipoproteins A-I and B among Korean employees and their partners. Methods : The study population consisted of 7,633 men and women (4,578 men and 3,054 women) residing in Seoul and Kyung-gee Do, with an average age of $43.5{\pm}8.3$ years. Blood samples were collected following at least 12 hours of fasting. Apolipoproteins A-I and B were measured using a Behring Nephelometer analyzer. The body mass index (BMI) for each participant was calculated as weight (kg) divided by height squared $(m^2)$. Information on health-related behaviors such as exercise, alcohol intake, and smoking habits was collected through self-administrated questionnaires. Results : The mean concentrations of Apo A-I were $132.6{\pm}22.3mg/dL$ and $142.9{\pm}24.8mg/dL$ in the men and women, respectively. The concentration of Apo A-I increased significantly across all age categories of men. The mean concentrations of Apo B were $101.7{\pm}23.2mg/dL$ and $87.8{\pm}23.5mg/dL$ in the men and women, respectively, and Apo B increased significantly across all age categories for both the men and women. Exercise and BMI were major determinants for Apo A-I and B levels. The 10th percentile of Apo A-I concentration was 109 mg/dL in the men and 113 mg/dL in the women, and the 90th percentile of Apo B concentration was 131 mg/dL in the men and 118 mg/dL women. Conclusions : For the prevention of coronary artery disease, we recommend that for individuals in the 10th percentile of concentration for Apo A-I and the 90th percentile of concentration for Apo B, active preventive interventions such as weight loss and exercise should be taken. This study, within its limitations, may be useful for evaluating apolipoprotein A-I and B concentrations in Korean adults.

Objectives : Polycyclic aromatic hydrocarbons (PAH) and toluene have been reported to induce reactive oxygen species and oxidative stress. This study was performed to investigate the effects of low level exposure to PAHs or toluene on the lipid peroxidation level in elementary school children and the elderly in a rural area. Methods : Forty seven elementary school children and 40 elderly people who were living in a rural area and not occupationally exposed to PAH or toluene were the subjects of this study. Information about active or passive smoking and diet was obtained using a self-administered questionnaire. The urinary 1-hydroxypyrene (1-OHP), 2-naphthol, hippuric acid and thiobarbituric acid reactive substance (TBARS) concentrations were measured, and these values were corrected with the urinary creatinine concentration. Results : In school children, the geometric means of the urinary 1-OHP, 2-naphthol, hippuric acid and TBARS levels were $0.02\;{\mu}mol/mol$ creatinine, $0.47\;{\mu}mol/mol$ creatinine, 0.14 g/g creatinine and $0.95\;{\mu}mol/g$ creatinine, respectively. Those values for the elderly were $0.07{\mu}mol/mol$ creatinine, $1.87{\mu}mol/mol$ creatinine, 0.11 g/g creatinine and $1.18\;{\mu}mol/g$ creatinine, respectively. The mean levels of urinary 1-OHP, 2-naphthol and TBARS were significantly higher in the elderly subjects than in the children. The urinary TBARS level was not correlated with the urinary 1-OHP, 2-naphthol and hippuric acid, but they were correlated with the age of the subjects. Conclusions : These results suggest that low level inhalation exposure to PAH or toluene does not markedly increase lipid peroxidation, and age is a significant determinant of lipid peroxidation.

Background: The simultaneous bilateral spontaneous pneumothorax is a rare clinical event. Contrary to the unilateral pneumothorax, the patients with simultaneous bilateral spontaneous pneumothorax sometimes complains of severe respiratory distress, cyanosis and chest pain without tention pneumothorax. It is often dangerous; therefore, the chest drain should be inserted immediately. Material and Method: Between March 1994 and February 2004, 802 patients were treated in our department for spontaneous pneumothorax. Among these, the simultaneous bilateral spontaneous pneumothorax developed in 14 patients (1.7%). Result: Out of fourteen patients, two females and twelve males presented with simultaneous bilateral spontaneous pneumothorax. The patient age ranged between 0 and 79 years with mean age of 31.2 years. In eleven patients, this was the first episode of pneumothorax. One patient had combined hemopneumothorax and two patients had combined pyopneurnothorax. Six patients had smoking history (42.8%, average 17.3 p-y). Five patients had pulmonary tuberculosis history and among these, two patients had active pulmonary tuberculosis. Three patients were died due to meconium-aspiration pneumonia (1 patient) and ARDS (Acute Respiratory Distress Syndrome) with pneumonia (2 patients). We treated these patients with nasal oxygen inhalation, chest drain insertion, thoracotomy, VATS (Video-Assisted Thoracoscopic Surgery) and chemical pleurodesis. Conclusion: The simultaneous bilateral spontaneous pneumothorax developed in 14 patients (1.7%) among 802 patients. Prompt insertion of chest drain is needed for a relief of severe symptoms, and to reduce the risk of recurrence, early thoracotomy or VATS should be performed rather than chest drain insertion only.

Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.

Erectile dysfunction (ED), also known as impotence, is the inability to attain and sustain an erection firm enough to have sexual intercourse. Frequent ED may be a symptom of health problems including heart disease, obesity, alcoholism, stress, smoking, and depression, that need treatment. This study aimed to effect of complex extract (CPL) including Cornus officinalis on sexual function factor in the erectile dysfunction rat model. The erectile dysfuction rat model was induced by cimetidine (500 mg/kg in 5% ethanol, oral injection 2 weeks). Rats were oral administered with different concentration of CPL in rat erectile dysfunction model. As a results, sexual function factors (NO, cGMP) significantly improved in CPL treated groups (CPL-300, 600, 900 mg/kg) compared to CON group. Serum testosterone was increased in a dose-dependent manner after CPL treatment. Furthermore, administrations of CPL restored lumen areas of the prostate in the erectile dysfunction rat model. These results indicated that CPL alleviated erectile dysfunction by increasing sexual function factor and testosterone in rat model. CPL could be used to natural treatement for erectile dysfunction. However, further study is required to identify active ingredient and its mechanism of erectile dysfunction.

This study was conducted to examine to causes and symptoms of stress and factors influencing stress management of workers in beauty shops. 811 people who were working in the shops located in Daegu City and Kyungbuk Province were selected as subjects of this study. Data were collected from April 10, 2000 to July 10, 2000. The results of this study can be summarized as follows. According to general characteristics of the respondents, female was 90.8%. 42.1 % of them was in their twenties and 73.7% of them did not marry. 57.5% of the respondents grew up in big cities and 41.1% had no religion. 63.6% was graduated from junior colleges. 44.6% of them worked for below I year and 33.9% earned below four hundred and ninety thousand won per month. 55.8% of them was satisfied with their work aptitude, while 34.2% was not satisfied with it. In the case of satisfaction level with working environment, ‘common level’ was 46.3%, while 12.8% of them was unsatisfied with it. In the case of stress level by factors of stress related to working, male was higher (9.34 $\pm$ 2.38 points). Those who grew up in towns or villages and those who belonged to the middle class showed high stress level. Those who married and those who graduated from high school also displayed high stress level. It also appeared that monthly income influenced the stress level related to working.. The extent of stress level influencing physical causes appeared in order of health condition, education level, sex, satisfaction level with work aptitude, economic status, and working hours. The extent of stress level influencing whole organizational level appeared in order of satisfaction level with work aptitude, working hours, education level, health condition, and sex. The extent of stress factors influencing depressed feeling of stress symptom appeared in order of working hours, sex, amount of smoking, absence due to stress, age, health condition, and education level. The extent of influencing factors on active stress management appeared in order of satisfaction level with work aptitude, health condition, size of the shop, drinking, sex, and the number of day off. The extent of influencing factors on avoidable stress management appeared in order of age, absence due to stress, drinking, health condition, and sex.

Volatile organic compounds (VOCs) are an important public health problem throughout the world. Many important questions remain to be addressed in assessing exposure to these compounds. Because they are ubiquitous and highly volatile, special techniques must be applied in the analytical determination of VOCs. Personal exposure measurements are needed to evaluate the relationship between microenvironmental concentrations and actual exposures. It is also important to investigate exposure frequency, duration, and intensity, as well as personal exposure characteristics. In addition to air monitoring, biological monitoring may contribute significantly to risk assessment by allowing estimation of absorbed doses, rather than just the external exposure concentrations, which are evaluated by environmental and personal monitoring. This study was conducted to establish the analytic procedure of VOCs in air, blood, urine and exhaled breath and to evaluate the relationships among these environmental media. The subjects of this study were selected because they are occupationally exposed to high levels of VOCs. Environmental, personal, blood, urine and exhalation samples were collected. Purge ＆ trap, thermal desorber, gas chromatography and mass selective detector were used to analyze the collected samples. Analytical procedures were validated with the“break through test”, 'quot;recovery test for storage and transportation”,“method detection limit test”and“inter-laboratory QA/QC study”. Assessment of halogenated compounds indicted that they were significantly correlated to each other (p value < 0.01). In a similar manner, aromatic compounds were also correlated, except in urine sample. Linear regression was used to evaluate the relationships between personal exposures and environmental concentrations. These relationships for aromatic and halogenated are as follows: Halogen $s_{personal}$ = 3.875+0.068Halogen $s_{environmet}$, ($R^2$= .930) Aromatic $s_{personal}$ = 34217.757-31.266Aromatic $s_{environmet}$, ($R^2$= .821) Multiple regression was used to evaluate the relationship between exposures and various exposure deter-minants including, gender, duration of employment, and smoking history. The results of the regression model-ins for halogens in blood and aromatics in urine are as follows: Halogen $s_{blood}$ = 8.181+0.246Halogen $s_{personal}$+3.975Gender ($R^2$= .925), Aromatic $s_{urine}$ = 249.565+0.135Aromatic $s_{personal}$ -5.651 D.S ($R^2$ = .735), In conclusion, we have established analytic procedures for VOC measurement in biological and environmental samples and have presented data demonstrating relationships between VOCs levels in biological media and environmental samples.
