This study was conducted to measure the exposure levels to noise for the middle and the high school students who worn headsets in the PC rooms. The noise levels from the headsets were measured with noise dosimeters, and the statistical relationships between the utilization pattern, user's views on the PC rooms and it's environment were analyzed for the selected PC rooms in the Ahnshan area. The results were as follows; 1. No significant difference was found in the number of uses and average time spent per day by education level and by sex of the users(p>0.05). 2. No statistical significant difference was found between the contents selected by education level of the users (p>0.05). The male participants overwhelmingly enjoyed the PC games (98.3 %) while females selected for listening music (75.0 %) with significant difference(P<0.05), followed by browsing internet and PC communications (70.0 %), PC game (66.7 %) and chatting (33.3 %). 3. The actual noise measurements of the headsets worn by the users of different sexes and educational backgrounds produced no differences(p>0.05), while a significant difference was found between genders (p<0.05). 4. For sound pressure level measurements, the weighted average(Lavg) of 84.5 dB(A) on the left headsets exceeded that of 79.8 dB(A) on the right headsets significantly(p<0.01) and the maximum value of 96.9 dB(A) on the left headsets exceeded the maximum value of 93.5 dB(A) on the right headsets(p<0.01). 5. The actual noise measurements of the headsets worn by the users of different sexes and educational backgrounds produced no differences(p>0.05), however, the contents selected by the users with different educational backgrounds were noted with significant difference(p<0.05) while no difference was found by gender(p>0.05).

The subacute toxicity of the combined vaccine (KGCC-95VI) for the prophylaxis against Japanese encephalitis and Hantaan virus infection, recently developed by Korea Green Cross Corporation, was investigated. KGCC-95VI was subcutaneously administered into the both sexes of New Zealand White rabbits at the dosage of 0, 10. 50 and 250 ml/kg body weight (20, 100 and 500 times the expected clincal dose) once a day for 30 days. There were no deaths and clinical findings during the experiment period. In both sexes. there were no statistically significant differences between the treated and control groups in urinalysis tests, hematological tests, blood chemistry tests and pathological examinations. The KGCC-95VI is considered not to have the subacute toxicity in the rabbits.

The current study was performed to determine the acute oral toxicity of P55A, a crude extract of 1 : 1 mixture of Phellodendron amurense cortex and Aralia elata cortex, in SD rats and beagle dogs. 5 rats of each sex were treated with a single dose of P55A orally at doses of 0 and 5,000 mg/kg respectively. Also 2 dogs of each sex were treated with a single dose of P55A orally at doses of 0 and 2,000 mgAg, respectively. After the treatment, clinical signs, and body weight change were observed for 14 days. All rats survived during the study and did not show any clinical sign. Body weight gain showed no significant difference between the control and treated rats. Grossly, no lesion was observed in the rats. All dogs survived during the study. In clinical signs, dark stool was observed in the 2,000 mg/kg treated dogs at day 1 after administration. The animals recovered from general signs at day 2 after administration. Body weight gain showed no significant difference between the control and treated dogs. Grossly, no lesion was observed in the dogs. It is suggested that the LD$_{50}$ of P55A by oral administration was estimated to be over 5,000 mg/kg in both sexes of rats and 2,000 mg/kg in both sexes of beagle dogs.s.

Objectives: Persistent organic pollutants (POPs) are known to be the detrimental chemicals in the body, even at low levels, and are stored in adipose tissue. Recently, POPs have been reported to be associated with chronic diseases, including cancer and cardiovascular disease, and aging and obesity are reported as common factors in chronic disease. However, there have been only a few studies on the associations of POPs with age and body mass index (BMI) in Korea. Therefore, we analyzed the associations of serum POPs levels with age and BMI in Korea. Methods: This cross-sectional study includes 444 subjects (253 men and 191 women) from the Korean Cancer Prevention Study-II (2004-2011). Serum levels of 33 polychlorinated biphenyls (PCBs) and 19 organochlorine pesticides (OCPs) were measured by a gas chromatographer (Agilent 6890) coupled to high resolution mass spectrometer (JEOL JMS-800D). Results: Concentrations of PCB 153 (men: 12.26 ng/g lipid, women: 10.50 ng/g lipid) and p,p'-DDE (men: 94.66 ng/g lipid, women: 96.66 ng/g lipid) were the highest among serum PCBs and OCPs, respectively. PCBs and OCPs were significantly positively correlated with age in both sexes. After adjustment for age, non-dioxin like PCBs were significantly negatively correlated with body mass in women. However, cis-heptachlor epoxide was significantly positively correlated with body mass index in both sexes. When analyzed by sex, stronger associations were shown between POPs and age in men and POPs and BMI in women. Conclusion: These results may provide baseline data for the study of POPs and for the health management field in Korea.

Background: To compare breast cancer incidence and mortality trends in Central Serbia between males and females in the period 1999-2009. Materials and Methods: In this descriptive study, mortality data were obtained from the National Statistics Institute and morbidity data were derived from Institute of Public Health of Serbia for the period of interest. Results: Breast cancer is a leading cancer in the female population of Central Serbia, whereas in male population it is not on the list of 10 leading localizations, concerning both incidence as well as mortality. In the period 1999-2009 the average standardized incidence rates of breast cancer were 60.5/100,000 in women and 1.4/100,000 in men, while average standardized mortality rates were 20.4/100,000 and 0.4/100,000. The average standardized incidence and mortality rates were about 45 times higher in females than males. Male breast cancer comprises approximately 2.1% of all breast cancer cases. The average age-specific mortality and incidence rates increased with age in both sexes. In the observed period standardized mortality rates of breast cancer increased significantly only in men ($y=0.320+0.0215{\times}$, p=0.044). Conclusions: The increase of breast cancer incidence in both sexes and mortality in men, indicate an urgent need for Serbian health professionals to apply existing cancer control and preventive measures. Male breast cancer is more present than in other world regions, with an outstanding increase of mortality, which demands a timely identification (screening) and adequate treatment. A national policy including mammography should be considered in the light of the newest findings.

The purpose of this study was to identify the differences in dietary consumption patterns according to the exercise level of Korean adults. The study subjects were the 7,370 Koreans aged 20 years and older of the 1998 Korean Health and Nutrition Survey. The dietary assessment was conducted by means of the 24 hour recall method. Data for individual exercise behavior were collected by interviews as part of the National Health Behavior Survey. Following the analysis of variances the Duncan＇s Multiple Range Test was used to test the differences in food and nutrient intakes among groups with different levels of exercise. Current exercise practices were reported by 22% of the male subjects and 15% of the female subjects. Unlike observations from the American and European studies, a greater amount of meat intake was observed more frequently among high exercises group than among middle and low exercisers in the case of the male subjects. This was reflected in the increasing levels of protein and fat intake in proportion to the exercise levels. However, the food and nutrient intake patterns of female exercisers were quite different from those of the males. The least intake of fatty foods was observed among the high exercisers. Energy intake from fat was the lowest among the high exercisers. These results may imply that the motivation to exercise was quite different between male and female Koreans. This dietary pattern may have a risk of undernution. Summerizing the results, whatever the motivation of the exercise, the Korean exercisers of both sexes had unhealthy dietary pattern. Therefore, nutritional education should be conducted to encourage the eating of a balanced diet along with exercise, among Koreans of both sexes, in order to promote a healthy lifestyle.

Background: According to increase in elderly populations, and change in lifestyle and cancer-causing behavior, the global burden of cancer is increasing. For prevention and control of disease, knowledge of population statistics of cancers and their trends is essential. This study aimed to investigate the epidemiology and trends of cancer in the province of Kerman: southeast of Iran. Materials and Methods: This analytical and cross-sectional study was carried out based on cancer registry data at the Disease Management Center of the Health Ministry from 2004 to 2009 in the province of Kerman in Iran. Common cancers were defined as the number of reported cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. Results: Of 10,595 registered cases, 45.3% (4802 cases) were in women and 56.7% (5,793 cases) occurred in men. The standardized incidence rates for both females and males were increasing during the six years studied. The most common cancers in both sexes during six years of studied were skin (13.4%), breast (9.35%), bladder (7.8%), stomach (7.45%), leukemia (7.05%), colorectal(5.57%), lung(4.92%), trachea(3.51%) and prostate(2.48%). Conclusions: Our findings revealed that the cancer incidence is demonstrating increasing trends in both sexes in the province of Kerman. This may be because of changes in lifestyle, increasing exposure to risk factors for cancer and increase of life expectancy. If this is the case, increasing public awareness of cancer risk factors is a high priority, together with introduction of large-scale screening techniques.

Background: Lymphomas represent the fifth most frequent cancer in Lebanon. However, little is known concerning epidemiologic characteristics and distribution of lymphoid neoplasms according to the 2008 WHO classification. Materials and Methods: We conducted a retrospective study of lymphoma cases diagnosed from 2008 till 2012 at $H\hat{o}tel$-Dieu de France University Hospital. Results: A total of 502 new cases of lymphoma were diagnosed at our institution during a five year period: 119 cases (24%) were Hodgkin lymphomas (HL) and 383 cases (76%) were non-Hodgkin lymphomas (NHL). HLs were equally distributed in both sexes with a mean age at diagnosis of 30 years. Among NHL, 87% (332 cases) were B cell lymphomas, 9% (34 cases) were T cell lymphomas and 4%(17 cases) were classified as precursor lymphoid neoplasms. Among B cell lymphomas, 44% (147 cases) were diffuse large B cell lymphomas (DLBCL), 20% (65 cases) follicular lymphomas and 8% (27 cases) mantle cell lymphomas. DLBCL were equally distributed in both sexes with a mean age of 58 years. Follicular lymphomas were characterized by a male predominance (57%) and a mean age of 60 years. Mantle cell lymphomas showed a pronounced male predominance (85%) with a mean age of 60 years in men and 70 years in women. Some 72% of patients having T cell lymphomas were men, with a mean age of 57 years in men and 45 years in women, while 65% of patients having precursor lymphoid neoplasms were women with a mean age of 22 years in women and 30 years in men. Conclusions: The lymphoma subtype distribution in Lebanon is unique when compared to other countries from around the world. In fact, Hodgkin and follicular lymphomas are more frequent than in most Far Eastern, European and American countries, while T-cell lymphomas and DLBCL are less frequent.

The food habits and health complaints were studied for 459 persons, 60 years and over, in the rural area, JKurye-Gun Chonnam, from April 28 to May 1, 1986. by the questionnaire sheets ; one was for the food habits, and the other was for health complaints(the standarized questionnair designed in Todai Health Index). The results obtained were as follows. 1) Mean score of the food habit was 11.2$\pm$3.5 in male and 10.8$\pm$2.9 in female. The score in both sexes showed a falling tendency as their ages increased. 2) THI scores in surfferings eye & skin, mouth & anus were higher (p<0.01, p<0.05, p<0.01) in female than in male. As age increased, the THI score showed a rising tendency. In case of male, THI socre in digestive organs was higher (p<0.05) in sixties than in other age. 3) The rate of living together with their family or spouse in the male aged was 77% higher than in the female aged. whilte the rate of celibacy in the female aged was 28%, higher than 3% in the male aged. DMF value was higher in female than male. The amount of alcohol ingestion were 2.1 and 0.6 Cup in male and female, respectively and the amount of smoking were 10.5 and 3.1 cigarettes in male and female respectively. Both alcohol intake and smoking were higher in male(p<0.01) 4) In case of male, the correlation coefficient between the score of food habit and THI score was negative in suffering eye & skin, mouth & anus, respectively, and in female it was negative in digestive, mouth & anus. As the score of food habit become low, the THI score become high. 5) Those living alone in both sexes showed a low score in food habit.
