The purposes of this article were three folds; to find general trends of the conception of love, sexual attitudes and mate conditions of unmarried men and women, to investigate relationships among them and to analyze the effect of significant variables influencing mate conditions. The samples were the 164 unmarried men and 235 unmarried women living in Kwang-ju. Major findings were as follows; 1) Unmarried men revealed higher concern in commitment of love and they were more liberal in sexual attitudes than women. Women desired higher level of mate conditions than men compared with themselves. 2) Women's conception of love was more related to their sexual attitudes and homogeneous mate conditions than men. Men's sexual attitudes were related to their homogeneous mate conditions, while those of women were related to interactional mate conditions. 3) Men's external mate conditions were affected by job, and internal mate conditions were affected by passion of love and sex role attitude. Men's homogeneous mate conditions were affected by attitude of premarital sexual experience, intimacy of love and conception of sexuality, and those of women's were affected by passion of love and age. Men's interactional mate conditions were affected by sex role attitude, job and education. Therefore unmarried men and women's conception of love and sexual attitudes were associated with homogeneous and interactional mate conditions.

Mating behaviour of the gammarid amphipod, Hyale rubra, was observed. H. rubra displayed precopulatory mate guarding: males clasped females with their gnathopods during copulation, forming a pair. Males also participated in embryo care during the incubation period. The population was small, and the sex ratio was almost equal. Energy allocation for mating effort and parental effort in the two sexes appear to be almost equal. The mating system was sequentially polygamous (or promiscuous) and there was conspicuous sexual dimorphism in the size of the gnathopod, which was used for mate guarding. However, there appears to be relatively weak sexual competition for mating opportunities despite conspicuous sexual dimorphism. H. rubra did not display territorial competition or external fertilization. Nevertheless, the male provided paternal care. Since H. rubra inhabit tide pools and live on algae, the polygamous mating system of the species can be explained by the polygyny threshold model. The evolution of mate guarding and parental care may have been favored by the species' low population density and harsh environments, an interpretation consistent with the optimality model.

This study aimed to clarify the attitude toward marriage, mate selection and sexual consciousness of japanese unmarried women students whom are believed in drastic change in a overall social value system and norm due to the introduction of western civilization, so as to provide some information of the same subject of our young women in similar situation. Survey was carried out for 177 unmarried Japanese women students of 3 Universities located in Osaka prefecture situation. Data were collected by means of Questionnaire and analyzed by SPSS BATCH SYSTEM. Result are as follows; 1) Pattern of mate selection- An increasing tendency of love match is recognized 2) Attitude to marriage-94.0% of correspondences want to marry and proper age of marriage, they think, is between 22-25 years. 3) Love-marriage relation- most correspondences answered that love is a prior condition for marriage, however, 32.8% of correspondences think, love can be built after the marriage. 4) Dating- most correspondences want free dating, however, they fell that they are lacking for opportunity and they are not confident in the selection of proper mate. 5) Premarital sexual intercourse-most correspondences show a very generous attitude toward premarital sexual intercourse if they are in love and this attitude becomes more remarkable among love match makers. 6) Equality of sexes-most correspondences answered that as women are different in physiological function from men, distinctive social roles of both sexes and the inequality of sexes are inevitable.

A female preference is a potentially complex function relating variation in multiple male traits with her probability of accepting the most optimal individuals as a mate. If mate preference is dominantly driven by additive fitness benefits, different females tend to be congruent in the decision of choice, whereas females will not necessarily share their mate preferences if non-additive benefits more strongly operate. Here, a sequential blocked design ($4{\times}4$) was applied to experimentally assess the relative contribution of additive and non-additive components to the female mate preference with Korean rosy bitterling, Rhodeus uyekii. In a total of 48 single stimulus presentations, behavioral elements of courtship activities were analyzed to derive the 'index of female preference'. Females showed a clear preference for males with more elaborate carotenoid colors, but mated randomly with respect to male body size and other color patterns. However, they were not individually consistent in their choice of mates, suggesting that non-additive components probably contribute to the evolution of female preference.

The purpose of this study is to find how the mate selection and sex consciousness reflected in Samhuk Yusa. We set up the following two questions for aim of this study. First, how are the real aspects and specific characters of mate selection reflected in Samguk Yusa? Second, how are the real aspects and specific characters of sex consciousness reflected in Samguk Yusa? The results can be summarized as follows; 1. Mate selection reflected in Samguk Yusa discussed into two major domains, one is spouse conditions and the other is marriage form. Men and Women are married at teenages, but the greater part of case is unidentified, so in order to approach this we need to analyse other historical documents. In men and women, standard of appearance and personality is difference. Analyzed case about appearance is a few, also we need to analyse other historical materials. More valued personality is wisdom in men, and in women more valued personality is virtue, brightness, graceful and mild. Through in case of to overcome the cultural gabs, the society must be open in every area. The marriage form is diversity, examples, free marriage, a marriage of convenience type, etc. Especially in aspects remarriage of man and woman is free in every class. 2. Sex consciousness reflected in Samguk Yusa discussed into three major domains, first is discussion about sex, second is premarital sexual behavior, third is extramarital. Through the case of discussion about sex is opened so there is not existence double blinded in sexual norms. Also through the case of premarital sexual behavior and extramarital, fidelity ideology does not yet come into existence.

With the purpose of determining the influence of sexual partners on the oestrous behaviour and to evaluate the accuracy of predicting the time from implant withdrawal to sexual receptivity following a treatment with Synchromate B (SMB), 15 adult Brahman cows were used in each of three phases. During phase I and n, random pairs of animals were induced to display oestrus one pair after the other at daily intervals, while in phase III, cows were induced alternately, every other day, one cow on the 1st day, two on the 3rd, one on the 5th, two on the 7th until all cows were treated. Sixty six percent of the cows in phases I and II, and 80% in phase III came into oestrous after treatment. The interval between implant withdrawal and, expected and observed oestrous was statistically different in all phases. Clustering of oestrous was evident. Cows displayed sexual receptivity within a. range of -24 to +96; -24 to +72 and -216 to +192 hours after implant withdrawal for the three phases, respectively, with a tendency for cows treated first (within treatments), to delay their oestrus signs and vice versa. In phase III, four cows showed oestrous behaviour with the implant in place. These in spite of not observing pre-ovulatory follicles. Correlation values of 0.99, 0.93 and 0.90 (P<0.05) were found respectively among treatments, between the number of cows coming into oestrus and the number of mounts observed. These findings suggest that there are social and behavioural factors in a herd that may override exogenous synchronisation treatments.

The sexual dimorphism of river sculpin (Cottus poecilopus Heckel) was investigated samples were collected from the Chiak stream from January 1993 to April 1994. Sexual dimorphism in body size and some morphological characteristics were observed in this species ; males were larger in size and had a larger mouth, anal fin, ventral fin and pevic fin than females. Males have a genital papilla and nuptial color, but females do not. Females may mate preferentially with large males. Larger males could be superior in nest defense and fanning of eggs to smaller ones, thus resulting in higher survival of eggs. Similary, the larger mouth in males could be advantageous in acquiring and defending their nests. Such sexual dimorphism in this species may reflect to outcome of sexual selection.

The purpose of this study was to find the general trends of college students'dating violence and coping behavior, to examine the difference among dating violence and coping behavior according to individual variables and relational variables, and to analyze the effects of these variables influencing coping behavior. The major findings were as follow; First, 99.1% of respondents reported that they had experienced violence at least once. The score of violence offense and violence victimization was lower than median. But male students' sexual violence was significantly higher than females'. Second, total score of coping behavior was lower than median. The score of female students positive coping was significantly higher than males, and that of mate students' avoidance coping was significantly higher than females. Third, the violence style varied with sex, altitude toward violence, anti-communication, and conflict. etc. Fourth, the positive coping behavior varied with victim response and victimization of physical violence. etc. The avoidance coping behavior varied with sex, age, grade, sex-role attitude, and partner's sexual violence. etc. ruth, the positive coping behavior was influenced by sex, partner's psychological violence, conflict, anti-communication. etc. The avoidance coping behavior was influenced by sex and grade.

The present study was undertaken to study the effect of thermal stress on sexual behaviour of superovulated ewes. Fourteen adult Bharat Merino ewes with an average body weight of 29.4${\pm}$2.34 kg were randomly allocated into two groups of 7 each. All the animals were grazed on natural pasture in the morning and evening hours and housed in shed during night. Animals of Group-1 were housed in shed from 10:00 to 16:00 h while the animals of Group-2 were exposed to thermal stress in a hot chamber ($40^{\circ}C$ /6 h/day). All the animals were offered drinking water once a day at 16:30 h. Meteorological observations i.e. dry bulb, wet bulb, minimum and maximum temperature were recorded daily inside the shed as well as in hot chamber throughout the experimental period. For superovulation of animals, standard protocol developed at the Institute, using FSH (Ovagen 5.4 mg in eight injections) and PMSG (200 IU) was followed. Various sexual behaviour parameters (circling, tail fanning, head turning, standing and approaching to ram) and estrus incidence (onset of estrus and estrus duration) were observed in both the groups. The different estrus symptoms were graded subjectively on arbitrary scale of 0-5 where 0 representing no sexual behaviour (0%) and 5 representing maximum intensity in sexual behaviour (100%). Estrus was detected with the help of a marked aproned ram of proven vigor at six hourly intervals. The average percent values for sexual behaviour parameters recorded in Group-1 and Group-2 animals were 53.7${\pm}$3.76 vs. 41.1${\pm}$2.18 for circling, 71.8${\pm}$5.42 vs. 49.0${\pm}$4.41 for tail fanning, 64.7${\pm}$3.30 vs. 44.5${\pm}$4.34 for head turning, 90.1${\pm}$3.16 vs. 75.8${\pm}$4.02 for standing and 63.8${\pm}$4.8 vs. 41.9${\pm}$4.58 for approaching to ram. Animals exposed to thermal stress had significantly lower values of these sexual behaviour parameters. The animals kept in shed exhibited estrus earlier (25.4${\pm}$1.12 h) and duration was higher (37.7${\pm}$1.59 h) as compared to animals exposed to thermal stress i.e. 30.6${\pm}$1.16 h and 31.7${\pm}$3.57 h, respectively. The findings of the study indicate that thermal stress reduces the intensity of sexual behaviour in ewes and may result in failure of the animal to mate and conceive.
