The aim of this study was to investigate the change of Heart Rate Variability(HRV) that mild cold stimulus on the forehead of healthy men induces. 34 healthy male subjects participated in the experiments. On the first test series, 15 subjects were applied to the mild cold stimulus by the devise for cold stimulation. In the second test series, 10 subjects With heat Syndrome and 5 subjects With cold Syndrome were applied to the mild cold Stimulus. Aa a additional test, 4 subjects with cold syndrome were applied to the warm stimulus in the last test series. We analyzed the HRV through measuring electrocardiogram.(ECG). The result of this study is comparatively clear. In the first test series, mild cold stimulus made parasympathetic nervous system be activated. In the second test series, mild cold stimulus made parasympathetic nervous system be activated both in subjects with heat syndrome and subjects with cold syndrome, and heat syndrome shows more active parasympathetic nervous system rather than cold syndrome subjects do. In the last test series, 2 subjects with cold syndrome respond the mild cold stimulus. That means warm stimulus of cold condition subjects made parasympathetic nervous system active in 2 of 4 subjects. We found out that mild cold stimulus on forehead makes parasympathetic nervous system be activated in healthy male, and it can be interpreted that mild cold stimulus make healthy human be relaxed. Also, subjects have different fondness of thermal stimulus according to their Cold or Heat condition Preferences. Last test series shows that we need to investigate effect of the warm stimulus heat syndrome subjects.

Purpose: This study was to compare the effect of center of pressure(COP) displacement and muscle activation onset during expected and unexpected sudden limb loading in subjects with low back pain and healthy control subjects. Most studies of COP displacement and muscle activation onset on postural task focused on sudden trunk loading or gross limb movements. Investigation of the COP displacement and muscle activation onset during expected and unexpected sudden upper limb loading deserves similar attention. Methods: For this study, 14 subjects with low back pain and 12 healthy control subjects are participated. Force plate and surface EMG measures were used to determine COP displacement and muscle activation onset under expected and unexpected sudden upper limb loading. Results: COP displacement and muscle activation onset under unexpected sudden upper limb loading were similar in subjects with low back pain and healthy control subjects. However, COP displacement and muscle activation onset under expected sudden upper limb loading were shortened in healthy control subject but not among the subjects with low back pain. Conclusion: The results provide evidence for impaired feed-forward control in subjects with low back pain.

This study investigated college students' patterns of visiting coffee shops which are formed by students' preferences. This study surveyed 300 college students in Seongnam. The subjects were consisted of 45.2% males and 54.8% females and the average age was 20.8 years. 41.3% of subjects visited coffee shops once or twice a month and 42.4% of subjects visited coffee shops on a random basis. 26.7% of subjects stayed in coffee shops for 1~1.5 hours. The main purpose of going to coffee shops was to enjoy specialty coffee. The subjects' first favorites was coffee with various kinds of syrups and second one was Americano. When the female subjects in Seongnam chose the coffee shops, they focused more on variety factors than the male subjects. The group of subjects who had monthly expenses of less than 400,000 won focused on price factors more than the group of subjects who had monthly expenses more than 400,000 won. Moreover, environmental factors were heavily related to the usage rate and staying time of the coffee shops. Above all, price factors and promotion factors affected subjects' choice of the coffee shops in Seongnam.

The purpose of this study was to investigate the anthropometric and blood biochemical characteristics, the dietary behaviors and health-related lifestyles of obese children in Incheon. A cross-sectional survey was conducted using anthropometric measurements, biochemical assessments and questionnaire analysis. The subjects included 7,055 obese children residing in the Incheon area (from 106 elementary schools). The degree of obesity was classified using the Obesity Index (OI) as light 20% ＜ OI ＜ 30% ; Medium 30% ＜ OI ＜ 50% ; Severe 50% ＞ OI. The statistical analysis was conducted using SPSS 10.0 program. Most subjects fell within the medium range of obesity. Most subjects had dietary problems such as overeating, unbalanced meals and skipping breakfast. The ratio of boy subjects eating green and yellow vegetables was lowe. when compared to that of the girl subjects. The boy subjects exercised more frequently and longer than the girls. As the Obesity Index increased, hypercholesterolemia significantly increased. The blood cholesterol levels of the subjects were positively correlated with body fat, waist/hip ratio and BMI; HDL cholesterol levels of the subjects were negatively correlated with the anthropometric data and the LDL cholesterol levels of the subjects were positively correlated with body fat. The blood triglycerides levels of the subjects were positively correlated with body weight, body fat, waist/hip ratio and BMI. Therefore, proper nutritional education and intervention are required for an improvement of obese children＇s dietary behavior, heath-related factors and blood lipid profiles.

The purpose of this study is to examine the implementation of the elective curriculum in academic high school. Elective curriculum of the high school seems to take more important status than that in the 6th national curriculum. The number of elective subjects of the high school increased from 60 different subjects for the 6th national curriculum to 79 different subjects for the 7th national curriculum. In addition, students can make their own courses and have a right to choose the subjects. In order to ascertain how elective subjects are being implemented and whether students can choose the subjects they wish to learn, this study conducted a national survey. The results of this survey are as follows. Despite the emphasis of the 7th national curriculum on the elective subjects in academic high schools, the curriculum implementation of elective subjects seems to be unacceptable. In most schools, only two typical courses such as humanities/social sciences and natural sciences courses are being offered for students as elective courses, and the scope of elective subjects students can choose appears very narrow. That's why we need to do research in order to improve implementation of elective subjects.

Diabetes is mainly evaluated by fasting blood sugar. The genetic and environmental factors influence the development of type 2 diabetes. In this study, the relationship between diabetes and family history of diabetes in Koreans was analyzed in consideration of body mass index and age. The study subjects were 4,274 subjects who received a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. In addition, subjects were analyzed by dividing them by gender and the median of age and body mass index. Diabetes prevalence was 8.9% of all subjects, and subjects with a family history of diabetes were 14.5%. The risk of diabetes was 2.80 times higher in subjects with a family history of diabetes than subjects without a family history of diabetes. In addition, in younger subjects, the risk of diabetes was 3.36 times higher in subjects with a family history of diabetes compared with subjects without a family history of diabetes. In this study, the family history of diabetes was significantly associated with diabetes. The relationship between family history of diabetes and diabetes was slightly higher in the younger group than in the older group. In order to obtain an accurate assessment of the association between diabetes and family history of diabetes, further prospective cohort study in the future is necessary.

Purpose: This study compared the subjective and objective sleep quality between subjects with and without thoracic hyper-kyphosis. Methods: Forty participants were divided into a hyper-kyphosis (n=17) and normal group (n=17) by thoracic spinal angle measurement. The subjective sleep quality was measured using PSQI, a self-report, and objective sleep quality was measured using an actigraphy that measures time according to sleep patterns. Results: The PSQI scores of subjects with thoracic hyper-kyphosis were significantly higher than those with normal thoracic curvature (p=0.013). The total sleep time and real sleep time were less in subjects with hyper-kyphosis than in normal subjects (p=0.006; p=0.029). The light sleep time was less in subjects with excessive spondylolisthesis than in normal subjects (p=0.010). Light sleep time was less in those with hyper-kyphosis, but deep sleep time was similar to the subjects with a normal thoracic curvature (p=0.003; p=0.140). Conclusion: Subjects with thoracic hyper-kyphosis had a decrease in subjective sleep quality, such as sleep discomfort, and objective sleep quality, such as a decrease in sleep time compared to normal subjects.

We investigated and analyzed students' perceptions of their choice of science subjects in the high school credit system and the reasons for their choice. To achieve this, the selection of science subjects was investigated for the second year of S high school over the past three years. Students selected an average of 1.54 science subjects, and it was found that the rate of selection of science subjects was gradually increasing by year. Students chose high in the order of life science I, earth science I, chemistry I, physics I, etc. in the science subject group. Students who wish to enter the natural and engineering fields chose life science I, chemistry I, physics I, etc., while, students who wish to enter the humanities society chose society and culture, life science I, ethics and thought, etc. On the other hand, the reason for choosing science subjects was 'related to college admission', followed by 'aptitude and interest', 'career and real life help', etc. physics I, chemistry I, etc., were high in the subjects selected according to the 'related to college admission'. The subjects selected according to 'aptitude and interest' were high in life science I, earth science I, etc. Physics I, chemistry I, etc. are recognized as subjects necessary for college entrance, and life science I, earth science I, etc., are found to be related to their interests and aptitudes.
