This thesis is to review 'Manhoengcheongnyu,' $\ulcorner$Cheongguyeongeon$\lrcorner$ in which sexual organs have appeared. The result of the review shows that a male narrator wants a large organ and a female narrator, a small one. Although there seems to be a difference between the male and the female with the framework of the size of the organs, they have the similar standpoint, Yeohapbujeol(如合符節), that they give and take the sexual feelings to satisfy their mates each other. As a consequence. $\ulcorner$eokgogeomgokuikeungurenarotgeugeotjochagilgoneopda$\sim$(#1993, *569)$\lrcorner$, refers to the other's satisfaction about the sizes of their own organs rather than the idea that the female sexual life is unilaterally oppressed by the male one. Sijo(時調) touches on organs which are 'bawdy and trifling,' and includes obscene comments. Eumdampaeseol(淫談悖說). Mentioning Eumdampaeseol(淫談悖說), the participants in a banquet of the singing space can be a part of its atmosphere, and by being protected by it, they can recite the sexual organs openly or they can grasp the inner meaning of the verse-joke in a refined and humorous fashion-which expresses organs indirectly. Thus, $\ulcorner$aheunahopgommeogeun老丈濁酒geolleo醉kemeokgo$\sim$(#1854, *534)$\lrcorner$, is not related with 'remorse about old age', but is merely a kind of Sijo(時調) about a sexual organ.

The purpose of this study is to identify the relationship between sexual attitude and risk behaviors, between risk behavior and sexual experiences in Korean girls high school students. The subjects for this study were 522 girls, who were samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul. The data were collected from June 22 to July 18, 2002. A structured questionnaire was used that included measurement of general characteristics, sexual attitudes, risk behaviors and sexual experiences. The data were processed with the SAS program, which uses descriptive statistics, t-test, and ANOVA in its an alyses. The results of this study are as follows : 1. The frequency of sexual experience is as follows ; 'holding hands' had the highest percentage, 57.4 7%, followed in order by 'arms around' 50.19%, 'act of embracing' 50.19%, 'kiss' 37.74%, 'french kiss' 30.84%, 'touch breasts' 8.62%, 'touch sexual organs' 3.26%, 'coitus' 2.30%, 'contraception' 0.77%, 'pregnancy' 0.19%, 'abortion' 0.19%, and 'prostitution' 0.19%. 2. The score of conservatives types was significantly different depending upon exposure to pornographic material and drinking. In comparison, the score of permissiveness types was significantly different depending upon exposure to pornographic material, drinking, and running away from home. But the score of pleasure seeking types was not significantly different than that of the risk behaviors types. 3. There was statistically significant difference in the sexual experience depending upon exposure to pornographic material, drinking, smoking, and running away from home. 4. In the relationship between sexual attitude types and sexual experience, there was a negative correlation between the conservatives types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was a positive correlation between the permissiveness types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was also a positive correlation between the pleasure-seeking types and sexual experiences such as 'touch sexual organ', 'contraceptions', 'pregnancy', and 'prostitution'. Based on the finding of this study, this society should develop a integrated program to prevent risk behaviors and sexual experiences in girls high school students.

Under standard condition (Han, et al., 1990: glucose 1%-nitrate 0.1% minimal medium, 30 ml in 9 cm plate, $10^6$ cells of inoculum per plate), wild type of Aspergillus nidulans developed both sexual and asexual organs in ballance, while velA1 mutant developed asexual ones preferentially. Increase of glucose concentration did not significantly affect the asexual sporulation. However, development of sexual organs were largely affected. It was greatly enhanced when favorable nitrogen source, for example, casein hydrolysate was added, which is contrary to the case of Neurospora or Saccharomyces where limitation of N source induces sexual development. On most of moderate C sources asexual development in $velA^+$ strain was largely inhibited except acetate on which only asexual spores were produced, while that in velA1 mutant strain was not affected. Lactose promoted the sexual development even in velA1 mutant indicating that lactose itself or its metabolic intermediate may induce sexual development independent of allelic state of velA gene. On other moderate favorable C sources, glycerol, galactose and ethanol, asexual development was largely inhibited in $velA^+$ strain but not in velA1 mutant strain. Sexual organs were, however, never produced on acetate. These results suggested that asexual development of wild type is largely dependent on C sources and the velA gene is involved in the repression of asexual development in not-enough-grown (non-competent) thalli resulting in preferential progression of sexual development.

The matured female and male of A. signifer differed in external morphology and body color. There were significant differences in PAD, PAB, PMP and PQR between matured female and male. Green color was very widely distributed in whole as nuptial color, that is similar to green and cyan color in the body part, yellow color in the ventral part and red and yellow color in the tail part. The nuptial organ of A. signifer was formed in a cluster on the horny substance of both sides above the mouth. There were 25~30 nuptial organs in a side. The nuptial organs disappeared with crumbling down from middle part of nuptial organ after spawning period. The nuptial organs disappeared mostly in September as non spawning period and a part of the nuptial organs remained as a vestige in the edges of both sides.

In order to find an useful condition under which the mutants defective in sexual development could be isolated, the effects of several cultural conditions on the developments of Aspergillus nidulans were examined. Among several conditions found to restrict the asexual sporulation but enhance the sexual process, the interference of aeration by sealing the plates with sealing film was the most useful one for the purpose of mutant isolation. Sealing at any time before 20 hours from inoculation prevented both sexual and asexual process. When the seal was removed after 24 hours, however, the mycelia developed only to sexual organs. Using this properity, the early morphogenic process of sexual development could be easily observed and a number of mutants that showed some defects in the process could be isolated. The mutants were divided into 3 groups, NSD (never in sexual development), BSD (block in sexual development) and ASD (abnormal in sexual development). NSD mutants never produced either the $H{\ddot{u}}lle$ cells or cleistothecia and some produced the asexual organs even when the aeration was restricted. BSD mutants were blocked in the process of $H{\ddot{u}}lle$ cell, cleistothecia, crozier, asci or ascospore formation. ASD mutants had defects in the amount of cleistothecia, time of cleistothecial maturation or color of ascospores.

Purpose: The purposes of this study are to examine the relationship between sexual knowledge and sexual attitudes and identify factors that influence sexual attitudes among Mongolian university students. Methods: A cross-sectional study was used. Participants include 200 students from 23 universities in U city in Mongolia. Data were collected from 1 December to 30 December of 2019. A self-report questionnaire through Google survey was used. Data were analysed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression analyse with SPSS 26.0 for Window Program. Results: We found the differences between sexual knowledge and sexual attitudes according to participants' general characteristics, sex education, and sexual knowledge (t=5.43, p<.001) and sexual attitudes (t=2.21, p=.028), sexual experience and sexual knowledge. There was no correlation with marriage thought among sexual knowledge, sexual health and pregnancy and childbirth, and sexual attitudes. The correlations between the remaining variables were high. Sexual knowledge was the most influential factor on sexual attitudes followed by the sexual act (β=.30, p<.001), reproductive organs (β=.29, p<.001), solving sexual desire (β=-.25, p<.001), sexual experience (β=-.16, p=.021), and sex education (β=-.16, p=.028) with an explanatory power of 20.0%. Conclusion: The findings of this study may provide a basic data and help to understanding of sexual attitudes among Mongolia university students.

Primordial germ cells (PGCs) of White Leghorn chicken embryos as a donor were transferred to Rhode Island Red chicken embryos as a recipient. At 48-50 h (stage 13-15) of incubation of fertilized eggs, donor PGCs, which were taken out from blood vessels of donor embryos, were injected into blood vessels of recipient embryos. Sex of the treated embryos was determined after the transfer of PGCs using remaining blood samples. In the present experiments, survival rate of the treated embryos was 33.3% for homo-sexual and 35.4% for hetero-sexual transfers of PGCs, respectively, when determined at 17 days of incubation. In this study, most of the treated embryos could not survive more than 18 days of incubation, though the reason for that was not clarified in the present work. The gonalds removed from embryos that died after 18 days of incubation and the organs from newly hatched chicks were examined for morphological and histological features. The gonads removed from the embryos with homo-sexual transfer of PGCs showed normal development in appearance. On the contrary, some (35.3%) of the embryos with hetero-sexual transfer of PGCs possessed abnormal gonads similar to ovotestis by histological observation. In cases where the gonads developed to be normal organs (64.7%) the sex of embryos was the same as recipient ones. The present results suggest that hetero-sexual transfer of the PGCs may bring about the possibility of development of the embryos bearing sexually different gametes, spermatogonia or oogonia.

The purpose of this study was to analyze the knowledge, attitude and experience of middle school boys toward Sexual Behavior. Data were collected by questionnaires from 246 middle school students in Korea, from June 4 to 30, 2000. The reliabilities of instruments were adequate(Cronbach's alpha= .56-.70). Data were analyzed by frequency, percentage, and ANOVA test using SAS V8 program. The results are as follows; 1. The mean score of knowledge of sexual behavior was $12.89{\pm}2.48$ and showed significant differences by the grade(f=5.0l. p=.0074). 2. The mean score of attitude of sexual behavior was $3.69{\pm}0.37$ and showed significant differences by the grade(f=3.06, p=.0386). 3. The correlation between knowledge and attitude is significant(r=.2290, p=0003). 4. The subjects experienced sexual behaviors such as. pornography(80%), night pollution (37.9%), masturbation(32.2%), Kiss(19.1%), Pet(8.7%), Coitus(3.2%). 5. The subjects being received sexual education were 94.7%, these former sexual educations is unsatisfied(40.7%). 6. The subjects who need sexual educations was 55.1%. The needs of sexual educations was high in the connection on with the other sex(51.9%), coitus(12.3%), sexual impulse (7.5%), sex organs(7.1%), sexual physiology (5.2%), masturbation(4.7%). In conclusion, subjects necessary to give sexual educations are suitable to the subjects's needs, grades and teaching methods such as multimedia program.

The purpose of this study was to make a comparative analysis of dietary habits, snacks, eating out and fast-food intake between students with a relatively early sexual maturity and others with a relatively late sexual maturity in a bid to grasp the impact of dietary behaviors on sexual maturity. The subjects in this study were 565 boys and girls who resided in Seoul and Gyeonggi province. They included fifth- and sixth-grade school children and seventh-grade middle school students. To classify the selected students according to the level of sexual maturity, the students of the same month age were divided into two groups in consideration of the stage of their sexual maturity and that of the other age groups. The early mature group was significantly taller and weighed more than the late mature group irrespective of gender. According to Tanner stages, the boys of the early mature group reached a 3.03 stage of sexual maturity when the sexual organs were taken into account, and those of the late mature group reached a 1.50 stage of sexual maturity. The girls of the early mature group reached a 3.43 stage of sexual maturity on the basis of breast, and those of the late mature group reached a 2.73 stage of sexual maturity. Concerning eating out, the early mature group ate out more frequently than the late mature group. In regard to snacks, the early mature group had a snack more often. The findings of the study indicated that there were differences in physical development and some dietary behaviors according to sexual maturity. The early mature group had a snack and ate out relatively more often than the late mature group, which showed that some dietary behaviors had an impact on the sexual maturity of the teens who arrived at the age of puberty.
