The purpose of this study was to compare sex role typing in relation to self-concept in 6th graders by to their residential area. The subjects were 6th grade children: 126 boys and 127 girls. The sample included 85 (42 boys, 43 girls) from a farming area, 111 (62 boys, 49 girls) from Pohang City, and 57 (22 boys, 35 girls) from a fishing area. The instruments used in this study were Shimer's self-concept measure (Suh, 1980) and Bern Sex Role Inventory (Byun, 1979). Statistical analysis of obtained data was by $X^2$ test; 2 (sex) x 3 (residential area) x 4 (sex role category) ANOVA; and $Scheff\acute{e}$ test. The results were as follows: Girls from the fishing area were more masculine than girls from other areas. Androgynous children and urban children demonstrated a higher self-concept. There was no difference in level of self-concept between urban boys and girls, but boys in both farming and fishing areas demonstrated a higher level than girls. In all 3 areas, androgynous children evaluated themselves positively whereas undifferentiated children evaluated themselves negatively. There were significant differences in self-concept according to sex, living area, and sex role category. In the city, the feminine category was related to a negative self-concept while the masculine category was related to a negative self-concept in the fishing area. But in the farming area, feminine boys demonstrated a higher self-concept whereas feminine girls demonstrated a lower self-concept.

The major purpose of this study was to compare the state anxiety of surgical patients by sex (male/female), area of operation (sex-organ/non sex-organ), and family planning (having the plan of child-bearing/having no plan of child-bearing). One hundred sixty patients who were to get surgical operation were equally divided into eight groups resulted from combination of variables of sex, area of operation, and family planning, The state anxiety of surgical patients was measured in terms of the discrepancy score between the state anxiety score on the State-Trait Anxiety Inventory (STAI) administered at a day before operation and the trait anxiety score on it which was administered at a day before discharge. In order to test statistically the differences among meant scores of the state anxiety obtained by eight groups, multiple comparisons were carried out by Scheffe method. The results of this study led to the conclusions that, (1) there was no significant sex difference in the state anxiety of surgical patients, when the area of operation and the family planning variables were disregarded, (2) the state anxiety of patients who were to get operation of their sex-organ was significantly higher than that of patients who were to get operation on the parts other than their sex-organ, when variables of the sex and the family planning were not taken into account, (3) there was no significant sex difference in the state anxiety of patients who were to Bet operation on the parts other than their sex-organ, when the family planning variable was disregarded, (4) the state anxiety of female patients who were to get operation on their sex-organ was significantly higher than the stale anxiety of male patients who were to get operation on their sex-organ, when the family planning variable was not taken into account.

The main purpose of this study is to explore the determinants of sex ratio imbalance at birth in Taegu which has experienced the extremely imbalanced sex ratio at birth since mid-1980s. This paper attempts to compare the determinants of sex ratio imbalance at birth, such as sex discrimination against women, son preference, prenatal sex identification followes by sex-selective induced abortions, among married women aged 25 to 44 in Taegu with those in Bay area, California in USA. The research is based on the survey data which were conducted in Taegu, Repulic of Korea and Bay area, California in USA. The findings of this analysis suggest that married women in Taegu are more likely to feel sex discrimination against women than married women in Bay area. Furthermore, the percentage of married women's effort for son bearing before pregnancy is much higher than that of married women in Bay area. We also have found that the percentage of sex-selective induced abortion in Taegu is six times higher than that of married women in Bay area. According to the logistic regression analysis, the determinants of sex-selective induced abortion among married women in Taegu are discrimination against women, son preference, prenatal sex identification. On the other hand, age is the only variable which has an important impact on sex-selective induced abortion among married women in Bay area. From the findings of this study, we can conclude that son preference based on Cofucianism is the most important impact on sex ratio imbalance at birth in Taegu where son preference is much stronger than other regions in Korea. The phenomenon of extremely imbalanced sex ratio at birth in Taegu is the result of combination of these factors, such as strong son preference, seeking to have at least one son within small family size, and prenatal sex identification followed by sex-selective induced abortion.

For the study on the sex ratio in natural populations of the different localities, the amphibian species were collected as the materials at the seven localities in Korea, and were obtained the following results. The sex ratios of each amphibian species suggest that each has it's own specific sex rations the following list. Rana nigromaculata H. : 109-39, Rana rugosa SCH. : 67.44, Rana temporaria coreana O. : 158.45, Hyla arborea japonica G. : 137.70. In Rana nigromaculata H. the average sex ratio was 109.39 as the above list, and its was reached statistically significant level according to the different localiies. The sex ratio was generally higher in the eastern area than that in the western area in this country. The sex ratio of the adult frogs of Rana nigromaculata H. was 135.18 , and it has a statistically significant level by each locality but the sex ratio of the younger frogs of the same species was 100.97 which was a little lower than that in the adult, and it was not laid at a significant level according to the localities. There is no doubt that the difference of sex ratios according to the localities was mainly due to the different ratios of the adult frogs which were effected on the constitution of sex by environmental factors in each locality.

The trapping efficacy of five commercially available sex pheromones manufactured in Korea, the Netherlands, North America, China, and Costa Rica was evaluated to determine the population dynamics of Spodoptera frugiperda and Mythimna loreyi and their relationships with the weather parameters of maize fields in Miryang, Gyeongnam Province, Korea in 2019. The results show that the sex pheromone manufactured in Costa Rica were more efficient at capturing S. frugiperda and M. loreyi than those manufactured in other countries. The lowest number of S. frugiperda moths were captured using sex pheromones manufactured in the Netherlands. We noted that more than four population peaks of both the moth species and weather parameters influenced the moth population dynamics in Miryang. A positive relationship was observed between the population of S. frugiperda and weather parameters, such as mean temperature, rainfall, and relative humidity, for sex pheromones manufactured in Korea. Furthermore, a positive relationship was recorded between the population of M. loreyi and wind speed for the sex pheromone manufactured in Korea. The results of this study suggest that the sex pheromones manufactured in Costa Rica are the best solution for the efficient capture of S. frugiperda and M. loreyi under typical weather conditions in the southern parts of Korea. In addition, the outcomes of this study are discussed in terms of population dynamics and integrated pest management for S. frugiperda and M. loreyi as alternatives to chemical management by maize producers. Further studies related to the continuous improvement in the capture efficiency of both moth species using sex pheromones are now needed.
