Authors reviewed 73 cases of primary skin cancer arising from head and neck, including comparative clinical data of 63 cases of squamous cell carcinoma and basal cell carcinoma retrospectively. There was no significant sexual predilection in each type of cancer and 77% of all cases were occurred after age of 50. The data of occurring site and occupation(farmer; 41%) implied that sunlight exposure strongly concerned in development of skin cancer. Comparing the data of 63 cases of squamous cell carcinoma and basal cell carcinoma, authors found out no remarkable difference in mean diameter of primary lesion at first visit of clinic, but some difference in mean duration, the percentage of the cases less than 1 year­duration and percentage of T1 lesion with no statistical significance(p>0.05). Combination of surgery and radiotherapy had relatively lower recurrence rate (11%) than surgery alone (13%). Squamous cell carcinoma had higher recurrence rate(34%) and metastasis rate(28%) than basal cell carcinoma; 6% and 3%, respectively(p<0.05).

To obtain information about knowledge and attitude toward sex, sexural experience and need of sex education, a questionnaire survey was conducted on 599 students who were attended in 2nd grade of 2 girls' high schools(A group: 190 girls), 2 vocational girls' high schools(B group: 205 girls), and 2 special girls' high school attached to industrial company(C group: 204 girls) in Taegu city between 20th and 25th April 1992. Mean score of knowledge toward sex of the total was 9.3. Mean score of A group was higher than that of Band C groups. Among the total students, vocational high school girls were the highest affirmative attitude towards the acquaintance and relationship with the other sex, and the next was special high school girls. Students of B group assumed the highest negative attitude towards artificial abortion, and the lowest was A group. Among the respondent girls, 31.1% did not experienced in the acquaintance and relationship with the other sex and 86 girls(14.4%) had experience with sexual affairs. Most of girls(96.9% of A group, 90.4% of B group and 86.8% of C group) agreed to necessity of sex education, and answered that current education on sex was insufficient to them(80.6% of A group, 82.6% of B group and 62.4% of C group). Among what the surveyed girls wanted to know about knowledge towards sex, they showed the highest interest on the acquaintance and relationship with the other sex(A group: 44.7%, B group: 45.4%, C group: 56.4%). And they showed the second highest interest on pregnancy and delivery(A group: 33.2%, B group: 32.6% , C group: 26.5%). There was no unique difference among each surveying item. Most of the students(A group: 46.8%, B group: 40.1%, C group: 36.3%) thought it better that the time they wanted to get education on sex in 5th or 6th grade of elementary schools and to have a regular curriculum on sex education.

Sex hormones not only regulate external sexual characteristics but several internal biochemical processes. It is well accepted that life-span of female is longer than that of male. Life-span is closely related with aging process in which free radicals are known to be involved. We investigated the effect of testosterone on free radical generating systems and lipid peroxidation based on the sexual difference. Lipid peroxide levels of male and female mouse were increased proportionately with age, especially in male mouse. Increase in enzyme activity of aldehyde oxidase with age was observed in male mouse, while no siginificant change in enzyme activity was found in female mouse. Enzyme activity of xanthine oxidase also showed similar results. It, however, was not significant statistically. Lipid peroxide level and xanthine oxidase type conversion ratio of male and female mouse liver homogenate incubated at $37^{\circ}C$, increased remarkably in proportion to incubation time, especially in male mouse. Lipid peroxide level and aldehyde oxidase activity were measured in normal male mouse, castrated mouse and testosterone treated-castrated mouse. Castrated mouse group showed decrease in lipid peroxide level and aldehyde oxidase activity compared with normal group. Treatment of castrated mouse with testosterone, however turned the level of lipid peroxide and aldehyde oxidase activity back to normal. From the above results, it might be concluded that testosteron could increase the activities of free radical generating enzymes which would result in the formation of lipid peroxide, consequently leading to aging.

This study was designed to analyze morphological characteristics of Korean young adults, norms and standard deviation of variables, sexual differences, correlationship between each area of face and correlationship between hard tissue and soft tissue. The primary sample consisted of 45 males and 57 females who were early and middle twenties and had acceptable profile, no history of previous orthodontic treatment, absence of remarkably large overjet and overbite, full complement of permanent teeth, Class I skeletal and dental relationships and good vertical facial proportions. Their cephalograms were analyzed morphologically with a computer morphometrics. Then the final sample - 25 males and 38 females - were selected within 1 S.D. of E-line, ANB, P/A facial height ratio, Interincisal angle, L1 to A-Pog, ODI and APDI. The results of the study were as follows: 1 In the form and proportion of facial skeleton there were no significant differences between males and females, but in the size males were larger than females. 2. The dental protrusion patterns had no significant sexual difference and no significant correlationship between protrusion of upper lip and inclination of upper incisor. But mentolabial angle had positively correlated with interincisal angle and negatively with inclination of upper and lower incisor. 3. In the relationship between nose and soft-tissue profile, males were larger than females in nasal length, height and angular measurements. 4. In analysis of soft-tissue profile, males were larger than females in the length and thickness. In the angular measurements and proportion of soft-tissue profile, there were no significant differences between males and females.

The purpose of this study was to identify and describe attitudes and beliefs that might act as barriers to addressing patient sexuality concerns and to determine the extent to which these attitudes and beliefs are influenced by personal factors such as age, gender, education. The Sexuality Attitudes and Beliefs Survey was used to assess nursing students(N=214). Important barriers to addressing patient sexuality reported by the majority of the students included not making time to address the concerns (86.9%) and Feeling confident in ability to address patients' sexual concerns(76.2%). A statistically significant difference was found in scores based on sex(p=0.03) and religion(p=0.02). Results of this study have implications for educational programs in dealing with patient sexuality.

This study analyzes the relations between perceived family characteristics, experienced abuse and mental health in childhood. For this, this study used row data by questionnaire, analysis, and frequency, ANOVA, t - Test, Pearson' correlation analysis. The sample was 118 children 10-12 years old in primary school. The findings are as follows. First, children perceived family cohesion and family adaptability highly, family adaptability showed a significant difference from the relations with a parent's job, a parent's academic level, and type of residence. Second, it appeared that some children experienced physical, emotional, and sexual abuse. Third, in general the mental health of children was good. Their mental health showed a significant relation to economic level of family, and type of residence, creating problems such as depression, anxiety, phobic anxiety, psychoticism. By family size, their mental health showed a significant relation to somatization, interpersonal sensitivity, depression, hostility, phobic anxiety, paranoid ideation, and psychoticism, Fourth, family cohesion and mental health perceived by children supported a linear relation to phobic anxiety, and family adaptability and mental health perceived by children supported the reverse -linear relation to somatization, anxiety, paranoid ideation, etc. Fifth, connections with perceived abuse and mental health as well as emotional abuse and mental health were also supported. Further more, on somatization, interpersonal sensitivity, depression, hostility, phobic anxiety, paranoid ideation, psychoticism, etc, a reverse-linear re lation existed. Physical abuse supported a reverse-linear relation with interpersonal sensitivity, depression, paranoid ideation, etc. and sexual abuse supported a reverse-linear relation with depression. These findings suggest that school and family have to concern themselves with the mental health of children because experienced abuse and family characteristics do indeed affect the mental health of children.

Rhus verniciflua Stokes (RVS) has been used as a food supplement and a traditional herbal medicine. In this study, we prepared various flavonoid fractions (RS, RW1, RW2 and RWE) from a hot water extract of RVS and their influence on male reproductive organs and spermatogenesis were studied in rats which were orally administered 200 mg/kg of them for 8 weeks. All experimental groups did not show any significant changes in body weight and blood clinical chemistry for liver function. Plasma testosterone level was elevated about 3.7, 5.2 and 6.3 folds in RW1, RW2 and RWE groups, respectively. The weights of testes and epididymides tended to increase slightly without the statistical significance in RW2 and RWE. The spermatozoon motility and epididymal sperm concentration were significantly increased (P<0.05) in RWE and RW1, respectively, when compared to the control group. There was no significant difference in histology and apparent shape of testes and epididymides among the control and the experimental groups. Collectively, RWE showed effectively the elevation of plasma testosterone level, spermatozoon motility and the epididymal sperm concentration without the significant increase of testis and epidiymides weights. When the component HPLC profile among the flavonoids fractions of RVS was compared, the ratio of components were only different. These findings suggest that the Rhus flavonoid fraction, particularly RWE, can stimulate the androgen-dependent male sexual function and it can be applied to the material of functional food for enhancing the sexual function.

A study on the effects of bisphenol A (BPA) on sex differentiation and gonadal development in medaka, Oryzias latipes, was investigated by histological examination. The fish were exposed to aqueous solutions of BPA at nominal concentrations of 50, 100, and 200 $\mu\textrm{g}$/L from newly-hatched larvae stage to 70 d. The ovaries of female fish were composed of oocytes at the chromatin nucleolus and peri-nucleolus stages at 20 d after the exposure. The testes contained a number of spermatogonia and spermatocytes at 30 d. In the process of sex differentiation. gonadal development was not different in all experimental groups until 30 d after the exposure. At 70 d after the exposure, however, advanced development of oocytes in the ovary and inhibition of spermatogenesis in the testis were observed in the BPA-treated groups compared to the non-treated controls. More females than males were identified in the 50 and 100 $\mu\textrm{g}$/L BPA-treated groups, in comparison to the 200 $\mu\textrm{g}$/L BPA-treated group and non-treated controls. Medaka exposed to 200 $\mu\textrm{g}$/L BPA were bigger compared to other experimental groups. The present study suggests that BPA may lead to problems in either mating or sexual behavior due to the difference in growth and disparity of sexual maturation between male and female fish.
