The purpose of this study was to examine the influence of make-up attitude and body-related value on clothing behavior. The subjects were 315 female college students in Gyeongsang provinces. The obtained data were analyzed by reliability analysis, factor analysis, cluster analysis, one-way ANOVA, Duncan's multiple range test, correlation analysis, multiple regression analysis and t-test. The major results of this study were as follows: First, four factors of make-up attitude were identified: pursuit of confidence, sociality, self-satisfaction, and positive image. Second, the subjects were categorized into three different types of groups according to make-up attitude and body-related value, respectively: high involvement type, low involvement type, and middle involvement type. Third, there was significant difference among three groups which were segmented by each make-up attitude and body-related value on clothing behaviors (sexual attractiveness, showing off, body-enhancement). Fourth, a significant positive correlation was found among four factors of make-up attitude and body operatability with clothing behaviors. Fifth, the important variables that affected the clothing behaviors were pursuit of confidence, self-satisfaction, and positive image of make-up attitude. Sixth, body-inclination significantly influenced sexual attractiveness of clothing behavior, whereas body-related value, unlike make-up attitude, only had marginal influence.

Investigations were made on population biology of Pampus echinogaster (Basilewsky, 1855) in the coastal areas of Korea, Yellow Sea, between August 2005 and July 2006. Population structure was not significantly different between male and females. Monthly variation of gonadosomatic index (GSI) of both sexes defined spawning period extending from March through July. A similar pattern was also observed in change at maturity stages. For males and females GSI was positively correlated with hepatosomatic index (HSI). Fecundity, ranging from 41,250 to 103,610 eggs, was related to body size, indicating that body size is the useful determinant of fecundity. The sexual maturity ($L_{50}$) was estimated as 14.98 cm TL for males and 19.32 cm TL for females. Parameters of growth estimated by the modified von Bertalanffy growth function model showed that the values of $L_{\infty}$ and K for combined data were 39.12 cm TL and 0.65 $yr^{-1}$. The growth performance index of this study (2.75) was higher than that of the previous study (2.45). This difference could be attributed to sampling method. The recruitment patterns indicated one normally distributed group. Percentage of the recruitment was 51.04% in the spawning season and the highest in August (19.78%).

In order to comparatively observe the salivary cariogenic factors contributing to permanent tooth caries development in each sexes of Korean, the author performed estimation of unstimulated and stimulated salivary flow rates, salivary viscosity test, and salivary buffering capacity test in 50 males and 50 females Koreans aged form the age 20 to 29. Thereafter, the data from the four kinds of caries activity test were analysed and evaluated comparatively. The obtained results were as follows. 1. Unstimulated salivary flow rate for five minutes was 2.2ml in males and 1.7ml in females but the sexual difference was not significant statistically. 2. Stimulated salivary flow rate for five minutes was 7.1ml in males and 4.8ml in females. 3. Salivary viscosity was 1.9 in males and 1.7 in females but the sexual diffrence was not significant statistically. 4. Salivary buffering capacity was 8.5 drops in males and 6.7 drops in females 5. It seems the stimulated salivary flow rate and buffering capacity to be the anti-cariogenic factors in the occurrence of permanent tooth caries in Koreans.

Morphological changes of the oviductal epithelium of the rat treated with hormones ($17{\beta}$-estradiol ${\mu}g$/day and progesterone 2.5mg/day) for ten days were observed transmission and scanning electron microscopically. The results obtained were as follows: 1. The cilia formation of ciliary cell(CC) was more accelerated by the treatment of estradiol than progesterone, but the balance of estrogen and progesterone was required for the maintenance of CC. The effect of hormone was different between the segments for the maintenance of CC. 2. The short secretory cell(SSC) was severely inhibited in the formation of secretory granules with single hormonal treatment but the activity of secretion was more inhibited by progesterone than by estradiol. 3. The long secretory cell(LSC) had not a great difference between estradiol and progesterone treatments as compared with the normal sexual cycle, but the formation of secretory granules was somewhat accelerated by progesterone treatment. 4. The formation of secretory granules of junctional cell (JC) was severely accelerated by estradiol treatment as compared with the normal sexual cycle. The formation of secretory granules during progesterone treatment, on the other hand, was inhibited completely, but the numbers of pinocytotic vesicles appeared at the cytoplasmic apical portion. 5. Three types of secretory cells, SSC, LSC and JC, on the rat oviductal epithelium could be suggested to have different cell tapes respectively from the morphological changes by hormone treatment.

Objectives : This study was done to figure out the incidence of Korean adolescents with gender identity problem and homosexual tendency. Self esteem and sexual liberality were also checked to evaluate the relation with these problems. Method : Subjects were 1,748 adolescents (359 middle school boys, 452 middle school girls, 483 high school boys, and 454 high school girls). DSM-IV-TR gender identity disorder criteria, Kinsey's sexual orientation scale, Hudson's short form sexual liberality scale, and Halter's Self-perception profile for children were applied to them. Result : 1) $15\%$ of the middle school boys, $16.7\%$ of the high school boys, $39.4\%$ of the middle school girls, and $40.5\%$ high school girls showed gender identity problem. Incidence of mild problem was more frequent in girls, however severe problem that suggested gender identity disorder was more frequent in boys, especially in high school boys. 2) Gender identity problem group showed lower self esteem than no problem group, especially in the middle school boys (p=0.033) and high school girls (p=0.020). 3) $17\%$ of the middle school boys, $5.4\%$ of the high school boys, $17.7\%$ of the middle school girls, and $12\%$ of the high school girls showed homosexual tendency. The order of more vivid homosexual orientation incidence was as follows ; $3.3\%$ in the middle school girls, $3.1\%$ in the middle school boys, $2.1\%$ in the high school girls, and $1.7\%$ in the high school boys. 4) There was no difference in the score of sexual liberality according to homosexual tendency. In high school girl, self esteem score was lower in homosexual tendency group than that of heterosexual group (p=0.039). 5) Gender identity problem group showed higher incidence of homosexual tendency than that of gender identity formation group (p=0.001). 6) The incidence of sexual identity problem was not changed by age, but homosexual tendency was decreased with age, especially in boys. Conclusion : Adolescents with gender identity problem or homosexual tendency showed low self esteem. Therefore, more attention on systemic evaluation for early detection in school based mental health and psychiatric management for them are needed.

The purpose of this study is to acknowledge how influences of abuse and neglect affect juvenile delinquencies. We created this study by surveying 180 random students from April 1, 2013 to August 5, 2013. Frequency analysis, t-test, and correlation analysis were used for data analysis in this study. The significance level of empirical analysis was verified as 5%. As the result, First, physical abuse depends on the age difference Second, emotional abuse depends on the lower ranked students. Third, The more often the sexual abuse, the more frequent the seriousness of juvenile delinquencies occurred. Also, Fourth, neglect had a significant difference in religion. The religion that was related to neglect is in this order: Christian being the most, non-religious, others and Catholic being the least. This study showed that compared to physical abuse, emotional abuse was a critical factor of having juvenile delinquencies. This result will be used for the prevention of juvenile delinquencies later on.

This study was conducted to investigate the laying period performance of two crossbred Korean native chicken (KNC) grand parent stock (GPS) layer during 20 to 40 weeks. A total of 351 20-week-old KNC GPS were allocated in a completely randomized design to give 4 birds per each cage. The chickens were fed commercial diets [i.e., week 20 - 32, crude protein (CP) 18.0% and metabolizable energy (ME) 2,850 kcal/kg; week 32 - 40, CP 17.0% and ME 2,800 kcal/kg)] and fresh water during the whole experiment period ad libitum basis. Body weight, age of sexual maturity, egg weight, hen-day egg production (HDP) and feed conversion ratio (FCR) were measured during the experiment period (week 20 - 40). The results show no significant difference in the Body weight, age of sexual maturity, egg weight, and hen-day egg production (HDP) except for egg weight. 1B had a higher egg weight on week 36 only. We expect that the reason why most factors showed no significant difference is the lack of nutrients caused by limited feeding which follows the standard feeding system for the grand-parent stock. These results provide basic information for laying data in 2-way crossbred Korean native chickens.

Various neurotransmitters have been proposed as possible mediators of penile erection. Especially, norepinephrine and serotonin might have a important role in sexual arousal and penile erection. And it could be hypothesized that the psychogenic impotence is associated with the depletion or imbalance of norepinephrine and serotonin from evidences, such as the symptomatic manifestation of depression and the antidepressantinduced sexual dysfunction. The authors investigates the association of norepienphrine and serotonin with psychogenic impotence. The psychogenic impotent group(PIG) consisted of twenty-three patients with psychogenic impotence and the controlled group(CG) consisted of twenty-seven patients without psychogenic impotence. PIG had no organic cause accounting for their erectile dysfunction. The Beck Depression Inventory(BDI) and the State-Trait Anxiety Inventory(STAI) were applied to each subject to assess mood, state anxiety(SA) and trait anxiety(TA). Plasma norepinephrine level from systemic blood and 5-hydroxyindoleacetic acid(HIAA) levels from 24-hours urine were measured in each subject. The mean score of BDI of PIG was significantly higher than that of CG(p=0.015). PIG had a tendency of higher TA compared with CG(p=0.054). And also SA was higher in PIG, but did not show significant difference(p=0.193). The level of norepinephrine was significantly lower in patient with psychogenic impotence(p=0.000). And the level of 24-hours urine 5-HIAA was lower in PIG but did not show significant difference(p=0.494). Although the authors did not exclude depressive disorders in PIG, the present findings suggest that psychogenic impotence might have higher depressive mood and trait anxiety, and be associated with the depletion of norepinephrine in systemic blood.

The purpose of this study is to research into the thermal condition and the weight of clothes suitable for the officers engagged in light works in an air-conditioned room in summer. The Major findings are as follows: 1. Thermal conditions of the working environment are $24.5^{\circ}C$ (Dry bulb temp.), $68\%$ (Relative humidity) and 2.6m/sec (Air Velocity). 2. Total clothing weights are 416.6 g/$m^2$ (male) and 340.9 g/$m^2$ (female). Underwear weights are 96.8g/$m^2$ (male) and 85.1g/$m^2$ (female). The latter turned out to be statistically significant in Sexual difference. 3. Means of the thermal sensation are 3.0 (comfortable; male) 2.7 ('Slightly cool' -'Comfortable'; female) and the relationship between clothing weights and thermal sensation proves to be significantly correlated in the case of female. 4. $66.7\%$ of the women and $37.1\%$ of the men feel sensation of coldness at the body's specific area and $79.5\%$ of the women and $54.3\%$ of the men reveals air-conditioning disturbance. 5. As the thermal sensation is close to 'cool-cold', sensation of coldness or air conditioning disturbance are showed up more frequently which is reversely related with weight of under-wear. It is also proved that air conditioning disturbances are influenced by sexual difference in addition to sensation of coldness and thermal sensation. 6. According to the result of experiment, we can have the idea that at condition $X_1$, the drop of limbs' skin temp. is remarkable. At condition $X_2$ skin temp. for distal limbs and mean skin temp. are raised and the falling degree is similar. At condition $X_3$, mean skin temp. and distal skin temp. are remarkably raised, and the falling degree decreases and the beats of pulse rate increase and diastoric blood pressure is lowered.
