Objectives: To investigate the drinking and smoking habits among the community residents of a city. Methods: We surveyed 1.973 adults from October 1, 2005 to November 16, 2005. The data collected on alcohol drinking habits involved frequency, age of initiation, amount of alcohol consumed, number of attempts to reduce consumption and reasons for reducing it. The data collected on smoking habits involved amount, age of initiation, duration, situations, and the number of attempts to quit smoking. These were analyzed with frequency, percentage, mean, standard deviation, $x^2$-test, t-test and ANOVA. Results: The rate of drinking was 67.4%; 83.1% among males, and 52.5%among females. Among all drinkers, the largest group (29.8%) drank once or twice a week. The mean age of initiation was 21.2 years; 19.9 among males, and 22.8 among females. The average consumed amount was 5.8 glasses; males consumed 7.4 glasses, and females 3.3 glasses. The consumption was the highest among those in fifties. The rate of attempts to reduce drinking was 33.4%, mainly for health reasons. The rate of smoking was 38.0%; 72.4% among males, and 5.5% among females. Among all smokers, the largest group (44.1%) smoked between 11 and 20 cigarettes per day. The mean of the age of initiation was 20.7 years; 20.3 among males, 25.6 among females. The mean smoking duration was 20.9 years; 21.3 years among males, and 16.2 years among females. The main reason for the initial attempt was curiosity. The most common situation for smoking was after dinner. The rate of attempts to quit smoking was 77.1%, mainly out of concern for one's health. Alcohol consumption among smokers was higher than among any other group of nonsmokers. Also, the age of drinking initiation among smokers was lower than among any other group of nonsmokers. Conclusion: This study highlighted the actual data on drinking and smoking habits among community residents. The study can be utilized for creating programs aiming at reducing the consumption of alcohol and tobacco or stopping it altogether. Therefore, it is now possible to assess the indicators for interventions in each population group. Finally, the groups of heavy drinkers and smokers are expected to be given priority for intervention program.

The objectives of this study were to analyze nutrition-related problems and to develop the nutrition education programs for high school students A survey was conducted with 500 students in the second grade level at high schools in Daegu who differed in socio-economic characteristics. In addition, body composition analysis was accomplished by the Inbody 3.0. The developed questionnaires were distributed and 481 questionnaires were collected with a 96.2% of response rate. Statistical data analysis was completed using SPSS WIN(ver.12.0) for descriptive analysis, reliability analysis, factor analysis, t-tests and $X^2$-tests. We first analyzed students' problems related to nutrition and environmental factors. In a question addressing skipping breakfast, only 11.5% answered they "do not eat" breakfast. In regards to BMI, the male students' degree of obesity was higher. Second, we analyzed living environments, which greatly influence dietary behavior. For the snacks-related categories, most of the students liked bread, cake and other snacks. When they chose the snacks, they mainly considered taste. There were significant difference among the males and females(p<.01) in terms of snacks intake habits, where 43.1 % of the males answered they snack "occasionally" and 43.4% of the females answered they snack "according to how they feel". In the case of beverages, the males consumed significantly more(p<.001). Based on their regional groups, the area A group preferred milk and milk products, and the area B group preferred soft drinks. As for the time of beverage intake, 77.6% of the females answered "with snacks", which was significantly higher than 61.4% of the males(p<.001), 12.2% of the males drank beverages after exercise. For late snacking, 68.0% of the male students and 71.1 % of the female students consumed late snacks. Most of them preferred bread, cake and other snacks. The reasons for taking a late snack were "when I feel hungry" by 61.8% of the males which was higher than the females(p<.001), 23.6% of the females consumed late snacks "impulsively". Ideally, in order to improve the food habits of high school students effective and practical nutrition education programs that consider gender and regional school group, should be carried out.

In order to study the feasibility of utilizing bivoltine foundation cross (FC2) males of the silkworm as male components with Pure Mysore (PM), six foundation crosses viz,CSR2 x CSR27, CSR27 x CSR2, CSR27 x CSR50, CSR50 x CSR27, CSR2 x CSR50 and CSR50 x CSR2 along with CSR2 pure breed were assessed for performance of parental crop,grainage, rearing and reeling performance. The foundation crosses exhibited better performance than CSR2 as a parental crop and male component which resulted in higher egg recovery. Though there was not much difference between PM crossed with FC2 and CSR2 males pertaining to important bioassay parameters, PM x CSR2 exhibited superiority in reeling traits particularly with reelability and raw silk %. This study reveals that FC2 seed cocoons can be utilized during exigency when there is a dearth for CSR2 seed cocoons but not regularly.

This study examined the characteristics of the National Assessment of Educational Achievement (NAEA) in Science according to gender. It investigated gender achievement differences in the science section of the 2010 NAEA, the ratio of gender difference in achievement, the ratio of correct answers within each content domain and behavioral domain, and the items which showed high differences between males and females. The results indicate first, that, for 9th graders, females outperformed males in academic achievement in science. Second, with respect to the ratio of correct answers, males outperformed females in the advanced and below basic level groups, but females outperformed males in intermediate level groups. Third, females outperformed males in knowledge and inquiry in the behavior domains, and in chemistry and biology in the content domains. Fourth, an analysis of the items showing the largest gender gap indicated that males outperformed females in interpreting data, while females outperformed males in the items concerned with daily life and items related to the memorization of rules. This research on gender differences in science will allow teachers to complement the weaknesses of students when they study science, and support improved instructional methods in science.

The purpose of this study was to examine the differences of clothing microclimates and the subjective sensations according to age, gender and clothing weight for $19^{\circ}C$ air temperature. This study was done to gain fundamental data related to saving heating energy and to improve health through wearing underwear (long johns) in lower indoor temperatures. The subjects were divided into four groups (6 young males, 5 young females, 6 old males, 6 old females), and our experiment consisted of three conditions; the first condition was wearing long underwear in $19^{\circ}C$ air (19CUW condition); the second condition was without wearing long underwear in $19^{\circ}C$ air (19C condition); and the third condition was without wearing underwear in $24^{\circ}C$ air (24C condition). The experiment showed that the clothing microclimate temperature and humidity was the lowest in the 19C condition and the highest in the 24C condition irrespective of age and gender. The clothing microclimate in the 19CUW condition was not significantly distinguishable from the other conditions. Clothing microclimate temperature and humidity when the subjects responded thermal comfort was $28\~34^{\circ}C$ and $15\~40\%$RH without any significant difference according to age and gender. For the thermal sensation, the 24C condition was regarded as the warmest environment by the four groups, and the next preference was the 19CUW condition (p<0.001). Young females and old males showed a tendency to feel colder than young males and old females. For the thermal sensation of hands and feet, the young groups felt the warmest in the 24C condition and the coolest in the 19 C condition (p<0.001). However, old males felt neutral for the foot thermal sensation without any significant difference between the three conditions. Old females felt neutral for both the hands and feet thermal sensations without any significant difference between the three conditions. Thermal preference was the highest in the 24C condition for the 4 groups. In the 19CUW condition, for the thermal preference, most young males and females responded 'No change'; on the other hand, mea of the old responded 'Warmer'(p<0.001). It was the 24C condition that the 4 subject groups felt the most thermally comfortable. In the 19CUW condition, over $80\%$ of responses of each group expressed satisfaction and in the 19C condition, over $80\%$ of responses of each group, except young females, expressed satisfaction. In conclusion, in view of the clothing microclimate and subjective sensations, the 24C condition was the condition that gave subjects the least cold stress and the best subjective preference. However, the 19C condition and the 19CUW condition was not such a cold stress as to give healthy subjects a thermal burden.

Normal values of serum electrolytes were determined for adult 36 females and 18 males, 1 to 6 years old, of Jindo dogs. The mean values, standard deviation and rangEs of sodium, potassium, chloride, calcium and inorganic phosphorus were studied and data analyzed to determine whether differences existed between the values of female and those of male dogs. The results obtained in this study were as follows: 1. The mean value of serum sodium was $143{\pm}1.5mEq/liter$, ranged from 138mEq/liter to 152 mEq/liter. The mean values for the females and males were $144{\pm}2.0mEq/liter$ and $142{\pm}1.7mEq/liter$, respectively. They showed that the female dogs had a tendency toward higher values than the male dogs, but no significant sex-related differences were observed. 2. The mean value of serum potassium was $4.6{\pm}0.2mEq/liter$, ranged frem 3.5mEq/liter to 6.0mEq/liter. The mean values for the females and males were $4.7{\pm}0.4mEq/liter$ and $4.5{\pm}0.3mEq/liter$. They showed that the female dogs had a tendency toward higher values than the male dogs, but sex differences were not found to be significant. 3. The mean value of serum chloride was $103{\pm}3.0mEq/liter$ ranged from 95mEq/liter to 117mEq/liter. The mean values for the females and males were $103{\pm}3.2mEq/liter$ and $103{\pm}3.3mEq/liter$, no sex differences showed. 4. The mean value of serum calcium was $5.2{\pm}0.1mEq/liter$ ranged from 4.7mEq/liter to 5.8mEq/liter. The mean values for the females and males were $5.4{\pm}0.1mEq/liter$ and $5.2{\pm}0.09mEq/liter$ respectively, no significant sexd iffere-nces were observed. 5. The mean value of serum inorganic phosphorus was $4.3{\pm}0.7mg/100ml$, ranged from 2.5mg/100ml to 5.8mg/100ml. The mean values for the females and males were $4.3{\pm}0.9mg/100ml$ and $4.1{\pm}0.8mg/100ml$, respectively, no sex differences showed.

The method of this research was based on the interview-survey with questionnaire. Chi-square test was the main data analysis method. The subject group was composed of 36 males and 67 females, the average age being 91.0 $\pm$ 3.2 years old for the males and 91.1 $\pm$ 3.4 years old for the females. The aged average height and weight were 161.0 $\pm$ 7.9 cm and 54.6 $\pm$ 7.8 kg in males, 141.0 $\pm$ 8.2 cm and 42.2 $\pm$ 7.9 kg in females which were lower than the Korean average standard but the mean BMIs of both male and female showed normal range. Their level of education was lower and they tended to be religious. The aged population might be economically poor. Their level of living standards tended to have been lower-middle and lower class. The mean age of their parents' death were 64.3 $\pm$ 17.2 years in males, 59.0 $\pm$ 14.9 years in females for the father and 70.9 $\pm$ 15.5 years in males, 66.8 $\pm$ 16.6 years in females for the mother. The rate of living together with their family or spouse in the female aged was $83.2\%$ higher than in the male aged. They tended to have engaged in hobbies that require less movement. Of the kinds of hobby, 'TV watching ($47.8\%$ in male and $44.9\%$ in female) was the highest. Ratios of the drinking and the smoking elderly were $30.6\%$, $25.0\%$ in male and $7.5\%$, $18.8\%$ in female but they tended to have never drunken and smoked. Of the subjects, $42.9\%$ spend 8$\~$9 hours for sleeping in male and $35.8\%$ spend 10 hours for sleeping in female. They tended to have not done any particular health behavior. The most common diseases were digestive disease in male, arthritis and hypertension in female. Most elderly males ($47.3\%$) and females ($61.2\%$) had 1$\~$2 diseases.
