Epidermophyton floccosum was known to be a frequently isolated dermatophyte agent of dermatophytosis in Korea, which regularly responsible for a small percentage of tinea cruris, tinea pedis, tinea corporis and onychomycosis. The purpose of this study was to investigate epidemiologic aspects of E. floccosum isolated in 71 patients from January 1998 to December 2007. The incidence of E. floccosum. was 0.07% out of a total of 107,026 dermatophytosis. The ratio of male to female patients was 6.9:1. Involved tinea were tinea cruris 44 (62.0%), tinea pedis 20 (28.2%), tinea corporis 2 (2.8%), tinea manus 2 (2.8%), tinea unguium 2 (2.8%), tinea faciale 1 (1.4%).

A flexible manipulator can move in the high speed even with the small driving torque. The dymanic equations of flexible manipulator which include 2 vibrational modes are derived using the clamped-free boundary condition. Simulation results of the 6th order model are well matched with experimental results. The hub angle of the flexible mainpulator can be controlled without vibration of the beam by the feedback of both hub angle and strain. The overshoot of the hub angle in the step response is reduced without sacrificing the rise time using the cycloidal function instead of the step function as the referenmce input.

The early hydration characteristics of the system $C_3S-C_3A-C_4AF$ according to the clinker composition variations, in order to establish the mutual interactionof clinker minerals during the portland cement hydration, have been studied. The early hydration rate of $C_3S$ was greatly effected by the change of $C_3S/C_3A$ ratio. The lower the $C_3S/C_3A$ ratio was, the faster the apex reaching time and the rate of heat liberation of the 2nd exothermic peak originating from the formation of $Ca(OH)_2$ were. The effect of $C_3S/C_3A$ ration on the amounts of $Ca(OH)_2$ formation was decreased, in process of hydration time, but the effect of $C_3S$ content was increased.

This research aims to examination the material characteristics changes of the ancient clay depending to firing temperature and to verify the firing temperature of the Joseon potteries from the Yongam site in Ssangyongdong of Cheonan, Korea. To this study, we conducted a firing experiments using the ancient clay that was verified raw material of the Joseon potteries from the study area in the temperature range from 500 to $1,200^{\circ}C$. The yellowish tint, the reddish tint and the specific gravity of firing samples increase according to firing temperature rise. But the absorption ratio and the porosity decreased under same firing temperature range. The soft potteries from the Yongam site has similar material characteristics with the fired samples at 800 to $950^{\circ}C$. And the hard potteries from the Yongam site bears the same relation to the fired samples at about $1,100^{\circ}C$. This result is considerably signification for the interpretation of firing temperature. The geochemical characteristics of the original clay according to the firing experiments, on the other hand, is not affected of temperature in this study.

An epidemiological study was performed on zoophilic dermatophytes. The number of patients with zoophilic dermatophytes diagnosed on clinical findings and culture at the Catholic Dermatological Clinic in Daegu City were 1,339 for 10 years from January 1995 to December 2004. Species of zoophilic dermatophytes isolated from 47,925 patients with dermatophytes were as follows; Trichophyton(T.) rubrum was isolated from 43,702 (91.2%), T. interdigitale 2,660 (5.6%), Epidermophyton(E.) floccosum 43 (0.1%), T. tonsurans 131 (0.3%), T. mentagrophytes 625 (1.3%), T. verrucosum 56 (0.2%), Microsporum(M.) canis 658 (1.4%), and M. gypseum 50 (0.1%). Zoophilic dermatophytes infections were chiefly Tinea facial in the cases of T. mentagrphytes and Tinea corporis in the cases of T. verrucosum, but Tinea capitis in the cases of M. canis. Number of patients with zoophilic dermatophytes by site and age were as follows; Most patients with infected scalps were young people under 15 years old. Infection of the trunk area (neck,chest,back) and extremities (arms, legs, hands, feet) were relatively high in those patients over 15 years old. M. canis were most frequently isolated in autumn and winter, and T. mentagrophyts and T. verrucosum were mostly in spring and winter.

Goguryo is the ancient dynasty which established the system of ancient state earlier than Baekje and Sila, and was a strong political and military power. Unlike the rock carving works of prehistoric times, mural paintings composed of line and color tones in tombs are characterized more by its social aspect and symbolism as a serious form of art than other cultural heritage of Goguryo. In response to that, this study analyzed the dress and ornaments of women found in Anak No. 3 ancient tomb, Susan-ri ancient tomb, Ssangyeongchong, which are the ancient tombs in Pyeongyang from 4th century to 5th century, have relatively more ancient tombs than any other places and preserved the mural paintings well, by using the plate, slide, literature and data related to relics in order to figure out the characteristics of women's dress and ornament in Goguryo, and the lifestyle and social aspect of Goguryo.

The number of children patients with tinea pedis and onychomycosis diagnosed on clinical findings and culture at the Catholic Dermatological Clinic in Daegu City were 144,446 for 2 years from January 2005 to December 2006. 120 children were suspected of having clinical onychomycosis or tinea pedis. KOH smears and cultures on the Potato corn meal dextrose agars (PDCA) were done for the suspected toe webs, nails and uninvolved neighbor toe webs. Socks were dusted and cultured to check contamination of clothes. Family infections were checked by questionnaire. The incidence was 92 (0.06%) out of 144,446 outpatients in tinea pedis, 28 (0.02%) in onychomycosis. Trichophyton(T.) rubrums were isolated from all of the 7 cases of onychomycosis. T. mentagrophytes was isolated from 5 cases of the tinea pedis patients and T. rubrum was isolated from 50 (92.5%) cases of the tinea pedis. The right side was predominant for onychomycosis of both toe nails (23 of 25) and finger nails (3 of 3). No fungal elements were detected from normal looking neighbor toe webs by KOH examinations. However, culture on PDCA agars showed T. rubrum isolates from 3 toe webs. 7 showed positive cultures from the socks. From the questionnaire, 94 had family infections.
