In this experiment, gene action were analyzed for seven silkworm varieties in order to obtain basic information on their genetic improvement by diallel crosses. The results obtained were summarized as follows : In F1 generation, over-dominance was shown by Vr-Wr graphic analysis in four characters such as cocoon length in female, bave weight, cocoon weight and boiling off ratio in both male and female, and partial dominance in four characters such as fifth instar period, cocoon layer weight, cocoon layer ratio and bave length. In F2 generation, the partial dominance in all characters were obtained. Components of genetic variance analyzed for five characters such as fifth instar period, cocoon width, cocoon layer weight, cocoon layer ratio and fibroin contents in F1 generation, and for four characters such as cocoon width, cocoon layer weight, cocoon layer ratio and frbroin contents in F2 generation showed that addition effects were higher than dominant effects.

This study analyzed the portrayal of adult characters in 176 picture books published in Korea by variables of character's external condition(sex, name, age and occupation), type(3-dimensional or flat), conflicts, and image. Standards for analysis of the picture books were devised by the researcher. Results showed that (1) adult male characters appeared much more frequently than female; they appeared most often without names and in order of older, middle aged, young adult. They appeared most often without occupations. (2) 3-dimensional characters appeared much more than flat ones. (3) Adult conflict situations were rare and were mostly interpersonal. They often resolved their conflicts by themselves. (4) The 20 kinds of images of the adult characters were mostly humorous, warm-hearted and attentive.

Using sexual differences between female and male as the indication of the degree of the physiological distrubance in the sex-limited larval marking strains or sex-limited egg colour strains, it was investigated whether the physiological distrubance caused y the translocated autosome fragment on the W-sex determination chromosome, have an effect on expression of the three quantitative characters; cocoon weight, cocoon shell weight, and cocoon shell percentage in the female silkworm. The mean values of the ratios of female to male the above two experimental groups were 127%, 107%, 85%, in cocoon shell weight, and cocoon shell percentage, respectively. On the other hand, those from the three normal stains, namely the basic stock strains, white egg strains, and hybrids were 129% for cocoon weight, 110% for cocoon shell weight, and 85% for cocoon shell percentage, respectively. From the results, it comes to the conclusion that the translocated autosome fragment on the W-chromosome has no influences on the expression of the quantitative characters of the female silkworm because sexual differences of the sex-limited strains were very similar to those of the three normal strains.

Phthalates and those metabolites have long history in industry and suspected to have deficient effects in development and reproduction. These are well-known anti-androgenic chemicals and many studies have examined the effects of these compounds on male reproduction as toxins and endocrine disruptors. Uterus is a key organ for proper embryo development, successful reproduction, and health of eutherian mammals including women. To understand the effects of the phthalate, the horizontal approach with a whole group of phthalate is best but the known phthalates are huge and all is not uncovered. Di-(2-ethylhexyl) phthalate (DEHP) is the most common product of plasticizers in polymer products and studied many groups. Although, there is limited studies on the effects of phthalates on the female, a few studies have proved the endocrine disrupting characters of DEHP or phthalate mixture in female. An acute and high dose of DEHP has adverse effects on uterine histological characters. Recently, it has been revealed that a chronical low-dose exposing of DEHP works as endocrine disrupting chemicals (EDC). DEHP can induce various cellular responses including the expression regulation of steroid hormone receptors, transcription factors, and paracrine factors. Interestingly, the response of uterus to DEHP is not monotonous and the exposed female has various phenotypes in fertility. These suggest that the exposing of DEHP may causes of histological modification in uterus and of disease in female such as endometriosis, hyperplasia, and myoma in addition to developmental and reproductive toxicity.

Intraspecific variation in morphometry of pine wood nematodes Bursaphelenchus xylophilus and B. mucronatus in relation to geographical locations in South Korea was investigated using morphometric characters (body length, a, b and c ratio, stylet length, and spicule length for a male nematode and V (%) value for a female nematode). B. xylophilus was isolated from Pinus thunbergii in Jinju (1998), Ulsan (2000), Yangsan (2000), Mokpo (2001) and Jeju (2004), and from P. densiflora in Gumi (2001). B. mucronatus was isolated from P. thunbergii in Jinju (1991) and from P. densiflora in Milyang (2001). The body length of male and female B. xylophilus had the highest coefficient of variability and showed significant differences among geographical locations. The V (%) value for female B. xylophilus showed the lowest coefficient of variability, changing little with geographical area and host plant. All morphometric characters in B. mucronatus except for stylet length and female body length showed no significant differences between locations or hosts, suggesting they may not be affected by geographical area or host plant.

In this dissertation, the analysis of the study of female customs from late Joseon Dynasty and their genre painting to research humors and its aesthetic senses in that certain era. The purpose of the genre paintings is to look at general populations in an objective point of view and endeavor better value of public life style to embody clear understandings of humanity. The artists such as Hong-Do Kim and Youn-Bok Shin expressed their arts based on reasonable reality with sarcastic but humorous and creative ways to criticize the society's problems with clear statements. Therefore, the formative characters are realism, exaggeration and coloring of the whole arts that represents as innovative and original genre of it's time. Hong-Do Kim and Youn-Bok Shin expressed the women in society as open minded with versatile and refined looks in their paintings as the reality was repressed and closed mind for women figures in late Joseon Dynasty. The female customs in the paintings has both suppression and expression in their dresses and exaggerated shapes of accessories and the use of color were also found. All of these elements has the aesthetic values of satirized eroticism, the hint of next evolution of the late Joseon Era under the conservative disposition of social characters and freedom of expression of playfulness. These elements were new developments and a step forward of female 'sex' and expression of satirized eroticism. The exaggerated and distorted forms and accessories demonstrates unbalanced and asymmetrical elements in humorous characters and they include spontaneity. Also, using the five traditional color schemes of Korean art displays humor in playfulness of an art with splendid and purity, duality of positiveness and artless, smart and elegance looks.

This article aims to analyze the perception of Korean-Chinese in South Korea to understand the mentality of South Korean people in a multicultural society through exploring Korean films in which Korean-Chinese characters have been represented since 2000. For this purpose, Korean-Chinese characters represented in Korean Films are divided into male and female. It could be said that South Koreans are biased against Korean-Chinese, who are considered 'others' under the economic and cultural hierarchy. Female characters are presented as 'pure' and 'frail' in the migration narrative while male characters are 'indecent' and 'brutal' individuals in crime narrative films. Meanwhile, Haemoo [Sea fog] is a story about economically weak Koreans and Korean-Chinese who were in economical conflict with each other, but were victims of the economical restructuring systems under neo-liberalism.

Nutrition is very essential for growth, development and reproduction. The quantitative impetus of nutritional factor on adult characters and reproductive fitness was studied in Antheraea mylitta by providing fresh leaves of Terminalia tomentosa for 1 to 4 times a day to $5^{th}$ instar larvae. All the characters have improved on giving fresh diet more times over the single diet. The adult weight has strong effect on the reproductive potential i.e., female pupa and moth weight, survivability, pupation rate, emergence percentage, fecundity, fertility, egg weight and hatched out larval weight. The improvement recorded to the tune of $70\%,\;77.1\%,\;115.4\%,\;36.7\%,\;45.9\%\;and\;218.3\%$ in larval weight gain, survivability, pupation rate, female pupa weight, moth weight and fecundity respectively when fresh diets were provided 4 times a day against single diet. The adult emergence percentage has increased from $66.4\%\;to\;96.2\%$ and fertility rose from $52.2\%\;to\;93.6\%$. The weight of eggs and the larvae hatched out of it also found to be significantly higher in 4 diets a day condition. The study revealed that optimization of fresh diet frequency should be maintained to obtain higher egg production and fertility in order to get vigorous larvae to continue the generation.

In this study, we investigated characteristics of sex-role stereotyping on 150 award-winning and traditional fairy tales (42 award-winning and 108 traditional fairy tales). The results were as follows: The depiction that female characters were rewarded for skills and competence, not for beauty, appeared more frequently in traditional fairy tales than in award-winning ones. Women were portrayed frequently as docile and passive in traditional fairy tales than in award-winning ones. Also, it was more frequently shown in award-winning tales than in traditional ones that male and female characters participated non-equally in physical activities.
