Pulmonary function test has been know to be greatly affected by body indices, such as sex, age, height, body weight, body surface area (BSA) and body mass index (BMI), so hat this study was focused to see the relationship between body index and flow-volume curves. Subjects were 156 (male 90, female 66) and they were examined for pulmonary function test in terms of body index and correlation/multiple regression analysis of flow-volume curves at Presbyterian Medical Center from March to August, 2009. The followings results after analyzing the correlation between body index and flow-volume curves. Although flow-volume curve FEF25-75% showed close correlation with age, body weight, and body surface area, but not with body mass index. In addition, multiple regression analysis was performed to see how each body index affects flow-volume curve FEF25-75%, and FEF25-75% dispersion was explained as 74.5% with age only, 94.2% with age and height, and 96% with age, height, and sex. Therefore, sex, age and height that are mainly used for predictive formular of pulmonary function test and nomogram were important factors for pulmonary function test itself, and further study must be done for other body index.

This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health questionnaire(GHQ-60) as a instrument of stress measurement. The number of subjects were 445 residents who lived in three areas(large city, middle city, and rural area) and they were individually interviewed in March, 1994. The results of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age, sex variables: (a) the residents in middle city among three areas had the highest level of stress; (b) the residents who were more than 60 in age had the highest level of stress: (c) the female residents had more stress than male residents, (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age, sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents' age.

Background: Sex influences is important to understand behavioral manifestations in a large number of neuropsychiatric disorders. We found electrophysiological differences specifically related to the influence of sex on psychopathic traits. Methods: The resting electroencephalography (EEG) activity and low-resolution brain electromagnetic tomography (LORETA) for the EEG spectral bands were evaluated in 38 teenagers with conduct disorder (CD). The 25 male and 13 female subjects had psychopathic traits as diagnosed using the Antisocial Process Screening Device. All of the included adolescents were assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria. The visually inspected EEG characteristics and the use of frequency-domain quantitative analysis techniques are described. Results: Quantitative EEG (QEEG) analysis showed that the slow-wave activities in the right frontal and left central regions were higher and the alpha-band powers in the left central and bitemporal regions were lower in the male than the female psychopathic traits group. The current source density showed increases in paralimbic areas at 2.73 Hz and decreases in the frontoparietal area at 9.37 Hz in male psychopathics relative to female psychopathics. Conclusions: These findings indicate that QEEG analysis and techniques of source localization can reveal sex differences in brain electrical activity between teenagers with CD and psychopathic traits that are not obvious in visual inspections.

This study examines the different degrees of sexual awareness shown among high school girls in urban and rural areas. The analysis was carried out by dividing these students into urban and rural groups. A questionnaire of 51 questions based on previous studies and a review of the literature was prepared for students in the two groups after two preliminary surveys, a reliability test, and correlation. There were 721 copies of the questionnaire in total which were distributed to students of 2 urban and 4 rural girls' high schools. The analysis of the results was carried out using by means of SPSS 10.0, and it became clear that girl's students' viewpoints toward sex, the actual circumstances of their acquaintance of the opposite sex, the access to information about sex, the content of current sex education at school and the ideal type of sex education, tended to show differences between the two groups. This study showed that the standardized and uniform content and methods of current sex education in public schools does not work properly. Sex education at schools in South Korea has reached a limit of their effectiveness to a point where research into more effective sex education is required.

This study was performed to examine dietary habits, nutrition knowledge and dietary behaviors of elementary school students by sex and skipping breakfast. The subjects were 3rd grade elementary school students in Ulsan area (total 1,349; 734 males and 615 females). The skipping breakfast group were 215 students, 15.4% of total subjects. Major reasons for skipping breakfast were 'have no time' 27.8%, 'no appetite' 26.9%, 'over sleeping' 14.9%. Females and eating breakfast group had better dietary habits than males and skipping breakfast group. The scores of nutrition knowledge of females were higher than those of males. The dietary behaviors scores of eating breakfast group were higher than those of skipping the breakfast categories. Our results showed that these difference by sex and skipping breakfast in dietary habits, nutrition knowledges, dietary behaviors should be considered in developing of nutrition education program for low-grade elementary school students.

Bovine drumstick of neutrophil leucocytes was studied on the quantitative and morphological characteristics and was evaluated as a diagnostic measure for bovine freemartin in newborn calves. Nuclear area of neutrophil (A, ${\mu}m^2$) and drumstick area (B, ${\mu}m^2$) were significantly correlated with average diameter of drumstick (ADD, ${\mu}m$) and following regression equations were obtained : $A=45({\pm}3)$ ADD-8, r = 0.74, $s.e.{\pm}0.6$, p < 0.01, $B=1.72({\pm}0.05)$ ADD-0.98, r = 0.93, $s.e.{\pm}0.1$, p < 0.01 Eight female siblings of heterosexual multiplets were diagnosed as freemartin from the results of chromosome analysis. Heterosexual multiplets had a very low frequency of drumstick in the nucleus of neutrophils irrespective of genetic sex. Diameters of drumstick fund in freemartin and male cotwin did not differ from those of normal cows. Examinations of drumstick in 800 neutrophils for both female and male siblings are concluded to be the best way to aid the detection of freemartinism of heterosexual twins at early life.
