  • Total particulate mater (TPM), $NO_2$ and $NH_3$ were measured simultaneously in the smoking and non-smoking locations during an eleven month period from March 1986 to January 1987 at three sites in Chicago : Illinois Institute of Technology Cafeteria, Rush-Presbyterian St. Lukes Medical Center Cafeteria and a downtown office building. From this study, the mean concentrations of $NO_2$ and $NH_3$ were not significantly different between the smoking and non-smoking locations at any sampling site ; however, there was a statistical difference for TPM between the smoking and non-smoking locations. Activity factor was useful for describing the contribution from indoor source. The linear regression analysis was reasonable method for discriminating the individual contribution of source to determine the emission factor. The TPM emission factor determined from this technique was in good agreement with value from the literature.

  • The purpose of this study was to investigate the nutritional status of serum minerals, ceruloplasmin, and ferroxidase activity in female adolescent students according to their smoking status. The subjects were 87 non-smokers and 88 smokers, who were female high school students. The smokers were divided into tow groups by smoking status, 35 light smokers(pack-year<1) and 53 smokers(pack-year$\geq$1). The serum concentrations of 6 minerals were determined by ICP emission spectroanalyzer. The serum concentration of ceruloplasmin and ceruloplasmin ferroxidase activity were determined. All data were statistically analyzed by SAS PC package program. The serum minerals concentrations of all subjects were in a normal range. There were significantly differences in the concentrations of serum copper, zinc, magnesium, and phosphorus by smoking status while there were no significant differences in the concentrations of serum iron and manganese by smoking status. Furthermore there were no significant differences in the ceruloplasmin concentration and ferroxidase activity by smoking status. In conclusion, smoking status altered the serum levels of some minerals in healthy young women. The minerals levels in light smokers with relatively short pack-year(pack-year<1) were altered compared to those in non-smokers or smokers. This finding seemed to be consistent with the results of previously published data related to antioxidant vitamin and lipid peroxide levels. However further research is needed to clarify these findings in female adolescent smokers.

  • In order to learn the emission characteristics of hazardous pollutants associated with environmental tobacco smoking (ETS), we measured the concentrations of major aromatic VOC and carbonyl compounds released from ETS. By acquiring the different smoke types of ETS, we were able to determine that the concentrations of those species range from ppb (normal exhaled air of smoker prior to smoking) to ppm levels (direct release of ETS without filter). Using these measurement data, we also evaluated the body-retaining rate of these compounds as the result of ETS. The results of our analysis indicated that predominant portion of them (e.g., > 99%) are retained as the result of cigarette smoking. To learn more about the potential impact of ETS, more extensive study may be required to assess the gross picture of pollutant deposition inside respiratory intake and their health-effects.

  • The purpose of a national health care system is to improve health care outcome among population. The objective of the study was to explore the determinants of health outcome in the 24 OECD countries between two health care financing systems. The study employed the pooled time series and cross-sectional analysis with tax-funded and social insurance-funded countries over the period of 1980 to 1999 using OECD Health Data 2002. The study revealed that health expenditure per capita, physicians per 1,000 of the population and calorie intake were positively significantly associated, smoking rate was negatively associated with health outcome while controlling all variables in the tax-funded countries. But in the insurance-funded countries, health expenditure per capita and the number of physicians were not statistically significant factors explaining health outcome. Only the calorie intake was positively associated with, and smoking rate, alcohol consumption per capita, and total nitrogen oxide emission per capita were negatively significantly associated with health outcome. In conclusion, healthy life style factors were much more important to improve health outcome in the both systems.

  • Environmental tobacco smoke (ETS) samples were collected separately in mainstream and side-stream smoke using a self-designed smoking machine, and a total 40 of PM2.5 was collected with low volume air sampler at indoor environments with and without ETS in Daejeon, Korea. About 20 trace elements including toxic metals like As, Cr, Mn, Se, V, and Zn were determined in PM2.5 and ETS samples by instrumental neutron activation analysis (INAA). It is found that the emission factors of K, Cl, Na, and Al were much higher than those of toxic elements for both mainstream and side-stream smoke. The average concentration of PM2.5 was enriched by 1.5 times at smoking area ($58.7{\pm}18.1{\mu}g/m^3$) than at smoking free area ($38.6{\pm}12.7{\mu}g/m^3$). The concentration ratio of each element between smoking and smoking free area were ranged from 1.1 to 6.0 except Cu (1.0); especially, Ce (6.0), La (5.2), K (2.3), and Co (2.0) showed higher ratio, which suggests that the ETS is one of the possible increasing factors of PM2.5 and elemental concentration at indoor environment.

  • The present study was initiated to examine the measures of dietary intake of Fe, Cu and Zn. The food duplicate samples were collected in Busan and its neighboring area, from the 69 middle-aged women (healthy non-smoking, mostly house wives), who provided informed consent. The samples were wet ashed by being heated in the presence of mineral acids, and Fe, Cu, Zn in the wet-ashed samples were analyzed by inductively coupled plasma - atomic emission spectrometry(ICP-AES). Dietary intake of Fe, Cu and Zn were 10.4 mg/day in Fe, 1.2 mg/day in Cu, 7.4 mg/day as arithmetic mean. The values for dietary Fe and Zn were lower, and the values for dietary Cu were higher than the recommended daily intake from Korean Nutrition Society. Further studies of Korean foods are needed to clarify the representative values for daily dietary Fe, Cu and Zn intake in the Korean population.

  • In this paper, several simulated devices were constructed for determining components of organic vapors emitting from decorative materials, daily use chemicals and from common behavior of human beings, such as smoking and cooking. The VOCs were preconcentrated on activated carbon and then desorbed by carbon disulphide. The results were obtained by GC/MS analysis and computer searching. It can be concluded that the categories of the sources and the components of organic vapors in indoor air are very complicated, and different sources of VOCs in indoor air have their own emission characteristics.

  • Polycyclic Aromatic Hydrocarbons(PAHs) contamination arises from several source including processing of food(smoking, direct drying, cooking) and environmental contamination of air, water or soil. A red ginseng is produced by steaming the root followed by drying. The methodology involved extraction with n-hexane and washing with water, clean-up on Sep-Pak Florisil Cartridges and determination by HPLC/FLD. The mobile phase was a mixture of acetonitrile and water in 8:2 by the isocratic elution and the excitation wavelength of fluorescence detector was 294 nm and its emission wavelength was 404 nm. The average recovery was about 105% and the relative standard deviation was 0.5. The levels of benzopyrene in the selected red ginseng beverage samples were not detected.

  • Objectives: The purpose of this manuscript was to review Intersectoral Collaboration policies for Tobacco Control. Methods: The author selected the WHO Framework Convention on Tobacco Control and adopted guidelines, and reviewed intersectoral and multisectoral collaboration policy recommendations. Results: There are 11 chapters and 38 articles in the Convention. In the Demand reduction policies included price and non price measures. The author selected a few non price measures for cross sectoral collaboration examples. They are protection from exposure to tobacco emission, education and communication, banning advertising, promotion and sponsorship of tobacco products, and offering treatment to tobacco use cessation. Inter sectoral and multi sectoral approaches could increase effectiveness, and better outcome of the tobacco control policy for implementation of many different articles of FCTC. Conclusions: It is important to give a specific role in structures of different government sectors and infrastructure for intersectoral collaboration. In addition, the role of civil society is very important for implementation of tobacco control policy effectively, and governments have to support the civil society for anti-smoking activities and campaigns.

  • Diabetic foot is one of the most devastating consequences of diabetes, resulting in amputation and possibly death. Therefore, early detection and vigorous treatment of infections in patients with diabetic foot are critical. This review seeks to provide guidelines for the therapy and rehabilitation of patients with moderate-to-severe diabetic foot. If a diabetic foot infection is suspected, bacterial cultures should be initially obtained. Numerous imaging studies can be used to identify diabetic foot, and recent research has shown that white blood cell single-photon emission computed tomography/computed tomography has comparable diagnostic specificity and sensitivity to magnetic resonance imaging. Surgery is performed when a diabetic foot ulcer is deep and is accompanied by bone and soft tissue infections. Patients should be taught preoperative rehabilitation before undergoing stressful surgery. During surgical procedures, it is critical to remove all necrotic tissue and drain the inflammatory area. It is critical to treat wounds with suitable dressings after surgery. Wet dressings promote the formation of granulation tissues and new blood vessels. Walking should begin as soon as the patient's general condition allows it, regardless of the wound status or prior walking capacity. Adequate treatment of comorbidities, including hypertension and dyslipidemia, and smoking cessation are necessary. Additionally, broad-spectrum antibiotics are required to treat diabetic foot infections.
