Obesity is defined as increased mass of adipose tissue, conferring a higher risk of cardiovascular and metabolic disorders such as diabetes, hyperlipidemia, and coronary heart disease. To get a better understanding of the role of a male sex hormone testosterone on obesity, we thus measured the effects of testosterone on white adipose tissue (WAT) mass, adipocyte histology and hepatic lipid accumulation in male castrated (CAST) C57BL/6J mice. Compared to male CAST control mice, testosterone-treated mice had the decreased WAT mass and the increased the number of adipocytes. Especially, histological data showed that the adipocyte size was reduced in a dose-dependent manner and was most effective at dose 150 $\mu$g per mouse for testosterone. In addition, the administration of testosterone resulted in the inhibition of hepatic lipid accumulation compared with control mice. Our results suggest that testosterone regulates adipocytes development and hepatic lipid metabolism, resulting in the prevention of obesity in male CAST mice.

Four cytoplasmic male-sterile lines of burley tobacco (Nicotiana tabacum L. ) and their male- fertile counterparts were evaluated for their characteristics in replicated field trials. Cytoplasmic male -sterile lines were comparable to the male- fertile varieties for agronomic and chemical traits and these suggest that the cytoplasmic male - sterility can be used in the production of hybrid seed without loss of vigour or undesirable changes On other characteristics.

Sexual behavior and reproductivity of male fIsh were studied as an in vivo screening method of endocrine disruptors. Male medaka (Oryzias latipes) were exposed to 17$\beta$-estradiol at nominal concentrations of 2 and 20 $\mu\textrm{g}$/l for 14 days. After exposure of the chemical, sexual behavior between male medaka and normal female which were injected with prostaglandin $F_{2\alpha}$ just before the test, was analysed by using video camera for one hour. Normal control male showed courtship dancing such as following, guarding, dancing and crossing while 17$\beta$-estradiol treated male did not show any type oj courtship dancing. Furthermore, fecundity and fertility were significantly decreased in the treated group. It was suggested that analysis of sexual behavior could be a useful endpoint for the screening of the endocrine disruptors.

The purpose of this study was to establish a set of standard values for the form of the nose and its relationship to other craniofacial structures in young korean adults in angle's class I occlusion. The subjects were 40 (20 male, 20 female) Korean dental students in angle's class I occlusion. Lateral cephalometric radiographs were used to determine the form of the nose and its positon relative to other craniofacial structures. The results were obtained as followed. 1. There was a significance between the registered male and female measurements in nasal height(P<0.05). (Male: 58.23mm Female : 54.62mm) 2. There was a significance between the registered male and female measurements in nasal length(P<0.05). (Male : 54.18mm Female : 49.38mm) 3. The vertical distances from the tip of the nose in Korean adults were significantly greater in the male(P<0.05) and were smaller in both sex in comparison with caucasian.

The purpose of this study was to investigate the state of eating out and the food preference of college students in Seoul. This survey was carried out through questionaires, and the subjects were 158 male and 159 female students. The result obtained were summarized as follows; 1) Female students had more regular breakfast than male students, and male students had more regular dinner than female students. 2) Male and higher grade students brought home-made lunches more frequently than female students, and others ate out in campus dinning room and off campus dinning room. 3) Most of subjects (77.3%) ate out more than once a day, they ate out in lunch time more frequently than other times. 4) Male and female students used different type of restaurant. 5) The most favorite food of male students in eating out was a Dongas, and that of female students was Nangmyun.

In Korea, a movement for founding space for women has been popular to improve the individualistic living environment. However, Consideration for male is laking in housing space. The purpose of this study is to: 1) analyze living status, using behavior of housing space, and actual state and need for male space, 2) plan apartment unit focused on specialized features for male residents. The study collected data from 108 men who were 30 years and older. The result of the study show that men were in need of consideration for a life of leisure, homeworking and household chores in dwelling space. Besides, most male residents didn't have their space even though they wanted it.

This study aims to investigate the levels of assets and debts that male- and female-headed households have in comparison to married-couple households. Toward this end, a series of analyses of data from the 2011 Korean Household Finance Survey on the assets and debts of single-parent households are conducted. The empirical results reveal that the amounts of assets and net worth of married-couple households were significantly larger than those of male- and female-headed households. A comparison between male- and female-headed households show that the latter were more likely to hold financial assets such as savings accounts, savings insurance and mutual funds. The amounts of assets of female-headed households were significantly larger than those of male-headed households. Furthermore, the amount of credit card debt in mele-headed households was significantly larger than that in female-headed households.

The present study was performed to establish the cephalometric norms and to study characteristics of craniofacial skeleton of Korean male and female with normal occlusion. The author studied and analyzed statistically vertical cephalometric measurements of the 52 adult male ranging in age from 18 to 26 years and 43 adult female ranging in age from 16 to 30 years with normal occlusion and acceptable profile. The results were as follows; 1. Cephalometric craniofacial norms and standard deviation chart were abtained about adult Korean male and female with normal occlusion. 2. Vertical dimensions of the craniofacial skeleton were larger in male than in female. 3. Lower face was more divergent in female than in male. 4. In simple correlation coefficients between vertical linear mesurements in male and female, high correlation were shown between ATFH and ALFH, PTFH and PLFH, ALFH and ALDH, PLFH and PLDH.

Eleven hot pepper accessions collected in Vietnam showed stable resistance to bacterial wilt as well-known resistance sources, MC4 and MC5, in repeated inoculation tests with different Ralstonia solanacearum isolates conducted from 2004 to 2010. Seven of these accessions (specifically KC981, KC1006, KC1021, KC1027, KC1045, KC1050, and KC1055) resulted in stable male sterile F1 plants in the crosses with a cytoplasmically male sterile (CMS) Chilseong (CMS-A, Srfrf ), and therefore, they were maintainers (CMS-B) with a genotype of Nrfrf. The rest (KC980, KC995, KC999, and KC1009) produced stable male fertile F1 plants in the crosses, and therefore, were restorers (CMS-C) with a genotype of N(S)RfRf. Therefore, the maintainer and restorer sources of resistance may be used in preference in breeding maternal (CMS and their maintainers) and paternal parents (restorers) for resistance to bacterial wilt, respectively, in the hybrid breeding system utilizing cytoplasmic male sterility.

Functional characterization of sex pheromones in olfactory responses is essential for the study of chemical communications in amphibians. Using Y-maze olfactory preference tests, we have investigated the olfactory res-ponses of male and female red-spotted newts, Notophthalmus viridescens, to the crude extracts of the opposite sex's genial and cloacal pheromones. Both male and female cloacal pheromone extracts caused the opposite sex to initiate olfactory responses by leaving the starting area in the Y-maze, but only subject males exposed to female cloacal pheromone extracts completed olfactory choice by entering the side arm of the Y-maze which received the pheromones. For genial pheromone extracts, only female genial pheromone extracts induced initial olfactory responses from test males. Neither male nor female genial pheromone extracts made the oppo-site sex complete olfactory choice. Pre-exposure of test females to male pheromone extracts increased the likelihood of initial olfactory responses. The latency for initial olfactory responses of test females that were previously exposed to male genial extracts was significantly shorter than that of control females.
