This study examined the economic structure of male one-person households, and investigated how it differed by male's age and marital status. Specifically household incomes, expenditure patterns, assets, debts, and other demographic variables were compared by age and marital status. From the 2000 National Survey of Household Income and Expenditure conducted by Korea National Statistical Office(KNSO), 1,389 male one-person households were selected. The findings of this study were as follows: First, the economic status of male one-person households was unstable. They were more likely to depend on labor incomes and transfer incomes, and had less property incomes and total assets. Their average propensity to consumption was higher than that of general households. Second, the economic structure of male one-person households showed large differ+useholders in age 50s allocated $48\%$ of household expenditure to the non- consumption categories, especially child or (ex)spouse support payments. The economic status of householders in age 60s and over was inferior to those of the other groups. Third, there were considerable differences in the economic status of male householders who had different marital status. Divorced and separated males had higher incomes and expenditures, but assigned large portion of their incomes to the non-consumption categories. Widowers' level of economic living, such as incomes, expenditures, and assets, was the worst among male one-person households.

This investigation was intended to find out the estrogenic effect of chlortetracycline (CTC) on vitellogenin induction in adult male Japanese medaka (Oryzias latipes). Vitellogenin (Vtg) produced in male fish has been used to as one of a biomarker of endocrine disrupters. The positive control was $17{\beta}-estradiol$ (E2) that induced Vtg in male fish. As a result, male and female fish were exposed to 0.1, 1, 10 and 100 ppm of CTC. Western blot results showed approximately 205 kDa, that is similar to myosin at high molecular weight range Sigma maker. Vtg band was showed fainted to 10 and 100ppm for chlortetracycline. Vtg concentration of CTC was qunatified by total protein quantification and ELISA. Exposure of the male fish to CTC of 0.1, 1, 10 and 100 ppm produced Vtg concentrations of 0.24, 0.12, 7.61 and 40.02%o, respectively, that value was elevated than control male fish (0.14%o). CTC exerted as a Vtg inducer in male fish from 10 ppm, but it was a reducer in female fish from 0.1 ppm level. The results say that vitellogenin induction patterns alter in male medaka treated with CTC, and that CTC may caused endocrine disruption in fish.

Self-immersed narcissism image that had been limited only a feminine image has being represented as a new masculinity image through various fashion magazine and TV advertisements. Besides, this makes a contribution of enlargement of concern about the beauty and fashion of the male. In the past, fashion has been created through the fetishism about the female body. But, new male image has been changed during only 30-40 years compared with the traditional various social, cultural, sexual body images had been changed for a long time. On the contrary, changed modem male image removes the interval of difference between the male and the female image. Now, representative techniques of the masculinity perform both accommodation and disobedience against social and cultural rules. Social body, which has been understood that appearance represents almost all things, makes the good use of the space of discipline and reformation. This paper is tended to grasp the characteristics of male body image expressed modem male fashion and TV advertisements based on the examination about the changed male body image.

The author had tried to identify the sex from single tooth by detecting F-body of Y-chromosome in the nucleus of the dental pulp cells of 70 persons aged from 4 to 61 years under a fluorescent miscroscope. The results were as follows : 1. In the cell nuclei of male and female dental pulp at refrigeratory, the rate of F-body appearancd ranged 42-86%(average 61.06%) in male, while it was 0-6%(average 1.86%) in female, indicationg that male could be distinctly differentiated from female by F-body. 2. With male and female dental pulp puterfide by leaving in at room temperature, the rate of F-body appearance ranged 35-58%(average 48.20%) in male, 1-3%(average1.70%) in female, indicating that it was possible to distinguish male and female by F-body. 3. Even in heat-treated male teeth at $100^{\circ}C$,10 mins, the rate of F-body appearace proved to be 32-56%(averaged 42.50%), also indicating the possibility of identifying male. 4. When detecting of F-body in process of time, the rate of F-body appearance did not show major charges. 5. It was reaffirmed that F-body detection method was a positive determination method of male.

This study presents comparisons between 286 male and female in their 60s in terms of the perception of their body shape. The results were as follows: 1. In the perception of male and female elders in their sixties on their body shape, a larger number of female elders considered that they were fat, short and heavy than male elder did. With regard to satisfaction with the body, male elders appeared to be more satisfied with their bodies than female elders, and both male and female elders were dissatisfied most with their abdomen girth. 2. The satisfaction of male and female elders in their sixties with their body shape appeared to be influenced more by their perception than their measured sizes. They were more satisfied with their body shape when they perceived that they had small girths, they were tall and they had long legs. In addition, female elders were more satisfied with their body shape when they perceived that their thigh girth and ankle girth were large. 3. As for perception on normal body types and fat body types and satisfaction, male elders' satisfaction with their body shape appeared to be less influenced by their body types than female elders'.

The genus Paracalanus Boeck, 1864 dominate zooplankton communities in waters off Korean peninsula. Zooplankton samples collected from four waters (Uljin, Hadong, Youngkwang, Cheju) were sorted for specimens belonging to the genus Paracalanus. Paracalanus sp. regarded to p. paMus or p. indicus were examined. Body of male has cephalosome dorsal hump (CDH). Urosomites have four segments in female and five segments in male. In male, antennule is symmetry and fused without geniculation. The male antennule carries more aesthetascs than those in female antennule. Female P1-P4 is similar to those of male in seta and spine formular. Spinules on surface of legs are different each other. The female P5 is symmetrical, and composed of 2 segment. In male, it is aymmetrical and left leg composed of 5 segments, right leg 2-segmented. Male found patch of fine spinule on terminal inner surface of outer process on fifth segment. Sexual dimorphism appear saliently in mouth appendages. Mandible lacks of gnathobase; maxillule is apparently reduced; maxilla degrades it i]l female and remains vestiges between maxillule and maxilliped; maxilliped terminal part indistinctly articulated and carrying behind three strong plumose setae. With the absence of gnathobase in male, we conclude that male Paracalanus sp. does not feed.

Objective: The aim of this study was to compare gait patterns of elementary school male students in higher grades according to their character styles. Method: 4 extroverted character male subjects (height: $141.35{\pm}7.75cm$, weight: $43.65{\pm}5.80kg$) and 4 introverted character male subjects (height: $145.38{\pm}8.94cm$, weight: $42.15{\pm}10.71kg$) participated in this study. Results: As for walk styles of elementary school male students in higher grades according to their character patterns, there was not significant differences in gait cycle, stride width, stride length and walking speed. According to examination of average ratio of maximum vertical ground reaction force according to their characters divided by weight, elementary school male students in higher grades with extroverted character showed 114.69% of weight and students with introverted character showed 122.82% of weight, which exhibited that students with introverted character had larger ratio as much as 8.13% than students with extroverted character. The statistical significance level was 0.000 showing significant difference. Conclusion: Our results indicated that male students in higher grades with introverted character press ground hard and walk with strong steps. On the other hand, male students with extroverted character walk with light steps.

On the basis of the study intended to research by crosssectional study keeps pace with semilongitudinal study the growthaccelerating phenomena that Maximum Growth age in teenager's body-height. By the random sampling method, the subject of study are 12659 persons(male; 6355, female; 6304) that they are from 7 ages to 17 ages in the whole country including the rural community. The measurement period passed three month days, the statistical data became electronic data processing system with computer. The other side, body-height and MGA of Koreans who had been for during the period from 1925 to 1966 proved transition of the growth-accelerating phenomena by research data reported between 1913 and 1983. The results are as follows; 1. The Growth and Development-Value of Body-height An age bracket the growth and development-value of body-height were, respectively, male is $123.88{\pm}5.05cm$ and female is $123.29{\pm}5.54cm$ for 7 ages group. these indices increased with age. the top-value reach, respectively. $169.08{\pm}5.62cm$ and $157.57{\pm}6.13cm$. The intersecting ages of male and female were the age $8.5{\sim}12.5$, during these periods, female excelled male but after these periods, male excelled female again. In case of body-height, MGA's are 7.0cm for male between 12 and 13 ages, and 7.01cm for female between 8 and 9 ages. As a rule, body-height of male excelled female but intersection phenomena of male and female appeared between 8.5 and 12.5 ages. By reginal groups, it is most prevailing is Seoul, and medium size cities and rural community rome in order. By regional groups, intersection phenomena of male and female are. a region of Seoul; $$8.5{\sim}11.5$$ ages a region of Daejeon; $$7.5{\sim}9.5$$ ages rural community; $$11.5{\sim}14.5$$ ages the whole country's average; $$8.5{\sim}12.5$$ ages By regional groups, the rate of maximum increase in a year are a region of Seoul; male is 7.23cm as 13 ages female is 7.65cm as 9 ages. a region of Daejeon; male is 7.85cm as 11 ages. female is 8.39cm as 9 ages. rural community; male is 7.65cm as 14 ages. female is 6.25cm as 12 ages. the whole country's average; male is 7.0cm as 13 ages. female is 7.01 as 9 ages. 2. Maximum Growth Age (M.G.A.) By reginal groups, maximum Growth Age's are as below in a region of Seoul, MGA's are 12.63 for male and 9.01 for female, which shows that MGA for female appears about 3.5 years earlier than that for male. In a region of Daejeon, MGA's are 9.20 for male and 8.93 for female, which. show that they are all much the same in M.G.A. In rural community, MGA's are 14.00 for male and 11.89 for female, which shows that MGA for female apperars about 2 years earlier than that for male. In the whole average, MGA's are 13.01 for male and 8.97 for femal, which shows that for female appears about 4 years earlier than that for male. For boy, M.G.A. shows fastest-growing in Daejeon, and Seoul and rural commonly come in order. For girl, It shows equal growth in Seoul and Daejeon, rural community comes later. 3. The M.G.A's in body height of male are respectively the age 15.02 in 1913, 14.23 in 1956, 13.86 in 1967, 13.62 in 1975, and 12.82 in 1981, while those of female are the age 12.0 in 1940, 11.52 in 1965, 9.53 in 1975, and 11.16 in 1980; these data show that the MGA of the Koreans has been getting younger. 4. The equation of linear regression of all the MGA's in body height are as follow; Male: Y(M.G.A)=$-0.020{\times}$ (the year)+15.19: female:Y(MGA)=$-0.028{\times}$(the year)+13.2549. 5. The corelation of all the MGA's in body height are as below; male; r=-0.329 female;r=-0.252 6. From the transition of the growth-accelating phenomena in 1980 we can capture the fact that the MGA's has been getting younger by 0.2 year per 10 years. 7. The MGA's in bodyheight are shown in table 4... 8. The future growth-accelating phenomena in body height are expected to show the similar tendency like that of the past, in 1910's but it should by more precisely reviewed after investigating the phenomena of the years directly ahead.
