The mode of inheritance of resistance to fenvalerate in the diamondback moth (Plutella xylostella L.) was studied using insecticide susceptibility and mixed function oxidase tests. Tehre were no differences in the concentration-mortality relationships between $F_1$ progenies $(S_{female}\timesR_{male},\;R_{female}\timesS_{male})$ obtained from reciprocal crosses with the susceptible and fenvalerate-selected strains(R), indicating the absence of sex-linked inheritance. Degree of dominance of the $F_1$ progenies $(S_{female}\timesR_{male},\;R_{female}\timesS_{male})$ were -0.50 and -0.46, respectively, in the insecticide susceptibility test and -0.85 and -0.81, respectively, in the mixed function oxidase test. These results suggest that inheritance of fenvalerate resistance is controlled by and incompletely recessive autosomal gene.

Human beings have advanced to release instinctive desire. Among the human desires, sexual desire is classed as a basic desire with appetite and has been expressed in many ways from prehistoric times to present. Despite the social and ethical restriction, expression of sexual image has been evolved with change of time and medium's development. Thanks to inventing the photograph technique, Change of pornographic image has showed a dramatic aspect since early 20th century. The video which delivers message more directly than the picture boosted this change, and the animation has experimented the expression methods and techniques numerously exceeding the limit of realistic image which reappeared by the device. In this thesis, I want to discuss how human beings express sexual desire in animation based on society's sex culture, and analyzed Japanese pornographic animation as its obvious cases. Japanese pornographic animation should be interpreted as the result of culture and society system's history. Through Heian, Edo and early Meiji period, Japanese sex culture has been kept very openly and preposterously. Transformation, metamorphosis, pedophilia, tentacle sex and exposure of specific body parts that are frequently appear in Japanese animation can be interpreted by ancient Japanese open sex culture like Wakashu, polygamy, sleeping in mixed sex group and pederasty. These Japanese odd sex culture is hard to find elsewhere and settled as intrinsic sexual expression in Japanese animation. This situation was institutionally severed by European Modernization's force at the end of World War II in 20th century. However, it seems they have been keeping their influence in a proper form until now. In this study, I discussed that pornographic animation should be interpreted in a frame of cultural phenomenon by researching the series of procedure that ancient Japanese open sex culture has been changed by the system. Sexuality which is found in general Japanese animation was started from their history, and the dichotomous expression about women can be understood that it is bent by institutionally regulated sexual opinion. Japanese history and culture can be understood that it is transformed to the dichotomy that are simultaneously according freedom of eroticism to the pornographic animation, and the fear and irresistible temptation about the woman's body as the other.

This study examined the reproductive health-related experiences of North Korean women defectors and their sexual knowledge, sexual attitudes, and reproductive health promotion behavior. Convergent parallel mixed methods were used. From April to July 2020, 8 North Korean women defectors in Seoul metropolitan area were recruited by snowball sampling. In addition, 175 participants in the Seoul metropolitan area, Chungcheong, and Gyeongsang Province were recruited. Content analysis was conducted to analyze qualitative data, and the SPSS 23.0 program was used. Three themes were derived: scared of sex due to ignorance', 'the embarrassing and annoying sex only for duty', and had to manage myself for sex under the limited situation.'. The subject's sexual knowledge was higher in the older and married groups, and the sexual attitude was more liberal in the younger group. Reproductive health promotion behavior was more active in the high economic level, and sexual knowledge and sexual attitude showed a positive correlation. Therefore, it is necessary to provide support systems and resources from the community to encourage reproductive health promotion activities. In addition, in terms of humanitarian aid, prioritization of the reproductive health of North Korean women is required.

The purpose of this study was to establish regression equations and probability charts for predicting the sum of mesiodistal crown diameters of unerupted unilateral canine and premolars from the sum of mesiodistal crown diameters of four mandibular incisors in Korean male and female. The plaster casts of 162 children(75 boys and 87 girls) among the contestees in 1994-2001 Healthy Dentition Contest in Seoul were measured. Sex differences are compared and the following results were obtained: 1. Bilateral comparison of sum of widths of permanent canine and premolars showed no significant differences for either sex(p>0.05). Sum of widths of permanent canine and premolars of male were significantly larger than that of female(p<0.01). 2. Regression equations for the prediction of sum of widths of permanent canine and premolars in each sex were as follows Male ${\Sigma}Maxillary$ 345 y= 10.45+0.53x Male ${\Sigma}Mandibular$ 345 : y= 10.07+0.51x Female ${\Sigma}Maxillary$ 345 : y=12.65+0.42x Female ${\Sigma}Mandibular$ 345 : y=11.70+0.42x Male+female ${\Sigma}Maxillary$ 345 y=11.01+0.50x Male+female ${\Sigma}Mandibular$ 345 : y=9.87+0.51x

Background/Aims Emerging evidence shows that the mechanism of irritable bowel syndrome (IBS) is associated with neurotrophic factors and tight junction proteins (TJPs). It is known that there are sex differences in the pathophysiology of IBS. The aim of the present study is to determine expression levels of neurotrophic factors, TJPs, and cytokines according to IBS subtype and sex. Methods From 59 IBS (33 IBS-constipation, 21 IBS-diarrhea, and 5 IBS-mixed) and 36 control patients, colonic mucosa mRNA expression levels of transient receptor potential vanilloid-1 (TRPV1), nerve growth factor (NGF), glial cell-derived neurotrophic factor (GDNF), and various TJPs were assessed by real-time polymerase chain reaction. Western blot was performed to determine levels of zonular occludens-1 (ZO-1). Serum levels of cytokines were measured by enzyme-linked immunosorbent assay. Results TRPV1, GDNF, and NGF mRNA levels were significantly increased in those with IBS-constipation compared to those in controls (all P < 0.05). However, they showed no significant difference between those with IBS-diarrhea and controls. Expression level of TRPV1 correlated with that of GDNF (r = 0.741, P < 0.001) and NGF (r = 0.935, P < 0.001). ZO-1 RNA expression levels were lower (P = 0.021) in female IBS-diarrhea than those in controls, although they showed no significant differences between male IBS-diarrhea and controls. Serum IL-1β levels in female IBS were significantly higher than those of male IBS, especially in IBS-constipation (P < 0.001). Conclusion Our results suggest that neurotrophic factors and IL-1β are closely related to IBS-constipation and that decrease of ZO-1 is an important factor in female with IBS-diarrhea.

This study is for the development of C.B.D. residential land that is available in the changeable housing market and urban planning paradigm. The results are as follows. First, we developed a Logit model to analyzed the suitable resident for living downtown and we used several variables in the model such as their living place, the location of their works, in come according to sex and age, and whether they have a car or not. Second, in analysis for the suitable residents using the Logit model, the main demanders who live in C.B.D. or have a job there and the young and old were chosen, Third, it shows that the suitable residents prefer semi-C.B.D. because it has convenient accessibility to C.B.D. rater quickly (in ten minutes). They prefer apartment and Mixed-Use building. Fourth, there are much residential land in semi-C.B.D. (63.7%) so as to support enough land in ease of redevelopment. The land price is tremendously low compared to that of land for business or for C.B.D.

This study was conducted to survey the feeding methods in Seogypo city and south Chejukun area. A random sample for this study a total of 355 mothers having babies under the age of 3 were surveyed. were boys. 45.5% were girls. infants' colostrum intakes in Seogypo sith and south Chejukun area were 69.9% and 63.1% respectability. Nother's education level affected colostrum intakes significantly. Baby's sex birth weight and mother's job affected the infants' feeding methods. The case of girl normal birth weight and mother's employment showed high percentage of bottle feeding. Bottle feeding was higher in Seogypo small city than in south Chejugun the country. Most of reasons for bottle feeding or mixed feeding was the lack of breast milk. The highest percentage of recommenders for breast feeding were baby's mother in Seogypo city area and were baby's grandmother in south Chejugun area. In Seogypo city area mother's education level did not affect the infant's feeding methods but in south Chjukun area mother's education level affected significantly.

Genetic hearing loss crosses almost all the categories of hearing loss which includes the following: conductive, sensory, and neural; syndromic and nonsyndromic; congenital, progressive, and adult onset; high-frequency, low-frequency, or mixed frequency; mild or profound; and recessive, dominant, or sex-linked. Genes play a role in almost half of all cases of hearing loss but effective treatment options are very limited. Genetic hearing loss is considered to be extremely genetically heterogeneous. The advancements in genomics have been instrumental to the identification of more than 6,000 causative variants in more than 150 genes causing hearing loss. Identification of genes for hearing impairment provides an increased insight into the normal development and function of cells in the auditory system. These defective genes will ultimately be important therapeutic targets. However, the auditory system is extremely complex which requires tremendous advances in gene therapy including gene vectors, routes of administration, and therapeutic approaches. This review summarizes and discusses recent advances in elucidating the genomics of genetic hearing loss and technologies aimed at developing a gene therapy that may become a treatment option for in the near future.
