This study is aimed at providing basic information necessary to set up education program and strategies to prevent high school students from smoking by school health care service. The main groups of study are 814 third-grade male students, 557 parents and 362 teachers, who were randomly chosen at 8 high schools in Seoul. Date analysis consisted of Chi-square test and percentage. The findings of the study are as follows: 1. The less interesting family life is, the more increasing current smoking rate is, (ex-smoking rate 53.5%, re-smoking rate 40.3%, current smoking rate 24.3%) 2. According th the results of $x^2$-test for the school life and the smoking, the students above ranking 41 showed th increase as 48.7% for continuous smoking, 18.9% for re-smoking, 67.6% for the present smoker. But it turned out that the students belonged to ranking 10 were not experienced the smoking. So it showed that there was a correlation between score and smoking. 3. It is noted that 93.3% of students, 93.3% of parents and 96.1% of teachers recognize harmful effect of smoking. But less than 70% those have recognized only half of all smoking knowledge. 4. There is a significant difference in the contends and types of education between parents and teachers. 5. For the time of home education and school health education to prevent the smoking, it turned out that 44.9% of students, 42.4% of parents, and 47.4% of teachers considered the optimal time as a high school' days. In addition it appeared that 40.5% of students, 33.4% of parents, and 54.6% of teachers recognized the necessity of the early education before the elementart school. For the optimal time to begin school health education, it showed that the middle school days were indicated from 56.6% of students, 52.7% of parents, the elementary school days were 54.6% of parents, the elementary school days were 54.6% of teachers.

Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-year-old male smoker presented with a painless lesion with a verrucous surface and erythematous spots on the hard palate. Excisional biopsy revealed oral mucosa consisting of hyperkeratosis, acanthosis, and elongated rete pegs. Subjacent connective tissue showed numerous foam cells with clear cytoplasm and pyknotic nucleus, negative on periodic acid-Schiff staining. Immunohistochemical analysis revealed foam cells positive for anti-CD68 antibody, while anti-KI-67 antibody was restricted to the basal layer of the oral epithelium. A final diagnosis of OVX was established. The patient showed no signs of recurrence after seven months of follow-up. Physical trauma and smoking habits can be directly related to the etiology of verruciform xanthoma because the lesion is chronic and inflammatory with slow growth, and sites if high trauma are more often affected by such a lesion. The hard palate is the second most commonly affected site, and local trauma caused by smoking can be a cause of this type of lesion.

Splenosis is defined as an autotransplantation of the splenic tissue after splenic rupture or splenectomy, and occurs most frequently in the peritoneal cavity. Splenosis is usually asymptomatic and is found incidentally. We report a case of combined intrathoracic and intraperitoneal splenosis in a 54-year-old male who worked as a miner for 10 years in his twenties, and was a current smoker. He was referred to our hospital for further evaluation of an incidental left diaphragmatic mass. Positron emission tomography-computed tomography and bronchoscopy were performed to evaluate the possibility of malignancy. There was no evidence of malignancy, but the spleen was not visualized. Reviewing his medical history revealed previous splenectomy, following a dynamite explosion injury. Therefore, splenosis was suspected and technetium-99m-labeled heat-damaged red blood cell scan confirmed the diagnosis. Radionuclide imaging is a useful diagnostic tool for splenosis, which could avoid unnecessary invasive procedures.

Background: Smoking among adolescents has been linked to a variety of adverse and long term health consequences. "Susceptibility to smoking" or the lack of cognitive commitment to abstain from smoking is an important predictor of adolescent smoking. In 2008, we conducted a study to determine the psycho-sociological factors associated with susceptibility to smoking among secondary school students in the district of Kota Tinggi, Johor. Materials and Methods: Two thousand seven hundred students were randomly selected by proportional stratified sampling. Analyses on 1,736 non-smoking students revealed that prevalence of adolescents susceptible to smoking was 16.3%. Results: Male gender (aOR=2.05, 95%CI= 1.23-3.39), poor academic achievement (aOR 1.60, 95%CI 1.05-2.44), ever-smoker (aOR 2.17, 95%CI 1.37-3.44) and having a smoking friend (aOR 1.76, 95%CI 1.10-2.83) were associated with susceptibility to smoking, while having the perception that smoking prohibition in school was strictly enforced (aOR 0.55, 95%CI 0.32-0.94), and had never seen friends smoking in a school compound (aOR 0.59, 95%CI 0.37-0.96) were considered protective factors Conclusions: These results indicate that follow-up programmes need to capitalise on the modifiable factors related to susceptibility to smoking by getting all stakeholders to be actively involved to stamp out smoking initiation among adolescents.

Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions, those suspicious for malignancy being linked with chewable forms, indicating serious effects.

Low back pain is generally defined as a complex symptom rather than a specific diseases entity, especially when musculoskeletal lesions of the low back, neurogenic, vasculogenic and discogenic lesions are present. Sixty to eighty percent of all human being have experienced low back pain once or more times during in their lifetime. Low back pain is a one of the commonest cause of physical impairment and induces disability the activities of everyday living or the activities of work. Today, low back pain plays important part for the loss of working capability from social, industrial field and individual daily life. But there are no study about incidence and prevention program of low back pain in rural peoples. This study was conducted to find out current status and characteristics related to low back pain in rural peoples(especially engaged in agriculture), so that could provide basic data to establish prevention program for them. The data were gathered from 301 rural adults(female 62.1%, male 37.9%) with low back pain by the structured interview in the 4 communities(south and north Gyeong-sang Do and Chung-cheong Do), and sampled at local hospital, local clinic, and health clinic center in May, 2000. The results were as followed. About one third of cases(35.5%) were aged from 60 to 69, 34.6% were smoker, and 91.4% not used to regular exercise. Low back pain frequently due to intervertebral articulopathy(42.5%), follewed by herniated intervertebral disk(19.9%), sprain(17.3%), vertebral dislocation(4.0%), and etc(16.2%). Above half of cases(56.5%) were a eight-hour workday, and 61.8% complained of low back pain during work. Mostly, period of agricultural experience was more than 20 years, and cultivated more than 2 crops. Low back pain is common to rural adults, therefore adequate resting time from work and lumbar strengthening exercise program needed to prevent low back pain in rural peoples.

Objectives: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors. Methods: The study population consisted of 3,000 male Koreans aged ${\ge}20$. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors. A two-part model was used to examine separately the effect of price on the decision to be a smoker, and on the amount of cigarettes smoked. Results: The overall price elasticity of cigarettes was estimated at -0.66, with a price elasticity of -0.02 for smoking participation and -0.64 for the amount of cigarettes consumed by smokers. The inclusion of other behavioral risk factors reduced the estimated price elasticity for smoking participation substantially, but had no effect on the conditional price elasticity for the quantity of cigarettes smoked. Conclusions: From the public health and financial perspectives, an increase in cigarette price would significantly reduce smoking prevalence as well as cigarette consumption by smokers in Korea.

This study was carried out to investigate the cadmium level in blood by age, gender, and smoking status among 162 elderly subjects in Gyeongnam Province from September 2006 to February 2007. The cadmium level in blood was analyzed by atomic absorption spectrophotometer. Subjects were classified according to smoking status and divided into smokers and non-smokers, smoking duration, daily smoking habits, age, and gender. Mean blood cadmium levels in male and female were $0.70{\pm}0.41{\mu}g/dL$ and $0.57{\pm}0.32{\mu}g/dL$ respectively, with no significant differences between the two groups. Cadmium levels in the blood of smokers and non-smokers were $0.57{\pm}0.32{\mu}g/dL$, $0.90{\pm}0.44{\mu}g/dL$ respectively, with the cadmium level of smokers being significantly higher than that of non-smokers. In comparison by age, cadmium levels in the blood of subjects over the age 70 years and over the age 80 years were $0.91{\pm}0.44{\mu}g/dL$, $1.02{\pm}0.39{\mu}g/dL$ respectively, showing a significantly higher blood cadmium level than that of non-smokers. when compared by the amount of daily cigarette consumption, there were no significant differences in the blood cadmium level between groups. However when compared by smoking duration, the blood cadmium level for the group of smoking duration of over 10 years was $1.15{\pm}0.38{\mu}g/dL$, significantly higher than $0.67{\pm}0.31{\mu}g/dL$ for the group of smoking duration of less than 10 years. In conclusion, longer smoking duration and older aged group showed higher cadmium level in blood. For more reliable results, further study of the elements that elevate the cadmium level in blood with more subjects and study variables will be needed.

Respiratory bronchiolitis-associated interstitial lung disease is one of the smoking-related interstitial lung diseases. Histopathologically, it shows respiratory bronchiolitis, which is characterized by the accumulation of pigmented macrophages within the respiratory bronchioles, accompanying peribronchiolar inflammation. Clinically, it is presented with respiratory symptoms such as a cough, sputum and dyspnea on exertion. It is well known that the incidence of malignancy in interstitial lung disease is high, but in respiratory bronchiolitis-associated interstitial lung disease the report of accompanying malignancy is rare. Here we report a case of a 60-year-old male heavy smoker presented with a cough, sputum and clubbing finger. A chest computed tomography (CT) of the patient did not show any shadow suspected of malignancy, but adenocarcinoma was found on a transbronchial lung biopsy and on a surgical lung biopsy with respiratory bronchiolitis-associated interstitial lung disease.

Backgrounds: The measurement of volume of isoflow has been considered as a sensitive test for detecting small airway diseases showing normal pulmonary function in a routine pulmonary function test. To evaluate the functions of small airway among dust exposed workers, the changes of volume of isoflow were measured and its applicability of managing early stage pneumoconiosis patients was studied. Method: The subjects were 67 male, pneumoconiosis with small opacity and FEV1>80%, FEV1/FVC>75% in spirometry and the controls were 20 male, no dust-exposed office workers. The maximal epiratory volume curves after inhalation of indoor air and $He-O_2$ gas mixtures were measured and ${\Delta}V_{max50},\;{\Delta}V_{max75},\;V_{iso}V/VC$ between the dust exposed and control workers were compaired. Results: 1) There were no significant differences between two group in ${\Delta}V_{max50}$ and ${\Delta}V_{max75}$. But the ratio of $V_{iso}V/VC$ of the subjects was siginificantly higher than that of the control (p<0.01). This study confirms that $V_{iso}V/VC$ is a very useful index in early detection of small airway dysfunction. 2) The ratio of $V_{iso}V/VC$ of the subjects was signigicantly different between only smoker group and mixed group(smoker and nonsmoker). It suggestes that smoking is an important cousative factor of small airway dysfunction. 3) As the profusion of the chest X-ray increased, the rartio of $V_{iso}V/VC$ increased, but no significant difference of $V_{iso}V/VC$ was found between categories of pneumoconiosis. The categories of pneumoconiosis and small airway dysfunction may not be related. 4) No significant relationship was established between the duration of work and the ratio of $V_{iso}V/VC$. Conclusions : It is concluded that the measurement of $V_{iso}V/VC$ is useful to detect small airway dysfuction of early stage pnuemoconiosis patents with small opacities but showing normal pulmonary function in a routine pulmonary function test.
