박장규 한국스포츠리서치 2005 한국 스포츠 리서치 Vol.16 No.2
The purpose of this was to analyze for the study on trait of thigh isokinetic strength and muscle endurance of soccer players. Subjects were regular group(n=8) and regular reserver group (n=10). They were measured and evaluated the strength of 60o/sec, 180°/sec work speed and muscular endurance of 240°/sec work speed after 50 time(extension/flexion exercise). The finding of study were as follows: 1. Regular group on peak torque strength at the lower work speed, 60"/sec, was extensor 165.1Nm, flexsor 85.2Nm which was significantly(p<.01) reserver than peak torque of high school group. However, each group in ratio of extensor to flexor at the same work speed showed imbalanc below to 60%. 2. Regular group on peak torque strength at the medium work speed. 180"/sec. was extensor 150.4Nm, flexsor 79.4Nm, which was significantly (p<.01) higher than peak torque of reserver group. However, each group in ratio of extensor to flexor at the same work speed showed imbalanc below to 60%. 3. Regular group on total peak torque at the high speed, 240"/sec. was extensor 118.2Nm. flexsor 119.1Nm, which was significantly(p<.01) higher than peak torque of reserver group. Reserver group on total work was extensor 1220.92J, flexsor 1225.21J, which was significantly (p<.05. p<.01) higher than total work of regular group. 4. Regular group on mean power at the high speed, 240"/sec. was extensor 146.3Watts flexsor 122.6Watts, which was significantly(p<.01) higher than mean power of reserver group. Reserver group on fatigue index was extenser 86.77%, flexsor 82.24J, which was significantly (p<.01) higher than fatigue index of regular group. Within the results of this study, the tindings have suggested the following conclusions for the advancement of strength. muscle endurance in Tae Kwon Do players : the exercising of Tae Kwon Do players to develop muscular strength. power, and endurance. should be aimed at the peak torque Improvement and balanced development of muscle strength for hamstnng strength.

박장규,권경술,유희준 대한의진균학회 2005 대한의진균학회지 Vol.10 No.2
Onychomycosis is not uncommon among nail diseases. A review of the reports between 1985 and December 2004 found it to be increasing (0.86%) until 1988 among the outpatients in the department of dermatology, but it decreased thereafter to the current average of 0.48% (0.43~0.53%). No difference was found in the occurrence between the genders. It was most frequently seen in patients aged 40~49 (22%) followed by those aged 50~59 (19.6%), 30~39 (19.3%) and 20~29 (13.6%) respectively, although some discrepancies were shown among the investigators. A new classification of onychomycosis was reported by Baran et al in 1998, approximately 25 years after the first classification of four types published by Zaias in 1972. They suggested onychomycosis should be categorized into five clinical types: distal and lateral (DLSO), superficial, proximal subungual (PSO), endonyx, and total dystrophic (TDO). The basis of the new classification was the pattern of nail plate involvement by mode and site invasion, rather than fungal etiology; therefore, Candida onychomycosis is not a separate category in the new classification. Nail growth rate can be an important factor that determines the initiation of the infection, the treatment periods or results in onychomycosis. It depends mainly on the turnover rate of the nail matrix cells, but is influenced by numerous environmental, physiological, and pathological factors.
