Objective: This study was to resolve the limitations of the experimental environment and to solve the shortcomings of the method of measuring human gait characteristics using optical measuring instruments. Design: A cross-sectional study. Methods: Fifteen healthy adults without a history of orthopedic surgery on the lower extremities for the past 6 months were participated. They were analyzed gait variables using the smart guide and the 3D image analysis at the same time, and their results were compared. Visual-3D was used to calculate the analysis variables. Results: The reliability and validity of the data according to the two measuring instruments were found to be very high; gait speed(0.85), cycle time(0.99), stride time of both feet(0.98, 0.97) stride legnth of both feet(0.86, 0.88) stride per minute of both feet(0.99, 0.96), foot speed of both feet(0.90, 0.91), step time of both feet(0.77, 0.71), step per minute(0.72, 0.74), stance time of both feet(0.96, 0.97), swing time of both feet(0.93, 0.79), double step time(0.81), initial double step time(0.84) and terminal step time(0.76). Conclusions: In the case of the smart insole, which measures human gait variables using the pressure sensor and inertial sensor inserted in the insole, the reliability and validity of the measured data were found to be very high. It can be used as a device to replace 3D image analysis when measuring pathological gait.

The aim of this study was to investigate the effect of chicken feet gelatin and wheat fiber levels on the quality characteristics properties of semi-dried chicken jerky. The obtained chicken feet gelatin swollen with hydrochloric solution (0.1 N HCl, pH $1.31{\pm}0.02$) was dehydrated via freeze-drying. Six formulations of chicken jerky that were prepared, based on the ratio of chicken meat, chicken feet gelatin and wheat fiber, were 100:0:0, 98:0:2, 99:1:0, 97:1:2, 98:2:0 and 96:2:2, respectively. The moisture content of semi-dried chicken jerky containing 2% wheat fiber was higher than that of jerky without the added fiber (p<0.05); moreover, an increase in the content of chicken feet gelatin also increased the moisture content. The drying yield of the samples increased with an increase in chicken feet gelatin. In addition, the drying yield of samples containing 2% wheat fiber was higher (p<0.05) than those without the added wheat fiber. However, the shear force of the samples significantly decreased with the increase in chicken feet gelatin content. Further, the shear force of the samples containing 2% wheat fiber was higher (p<0.05) than those without the added wheat fiber. No significant differences, except for color, were observed in the sensory analysis among the treatments.

본 연구에서는 축산 부산물인 닭발을 산과 알칼리에 각각 침지하여 제조한 젤라틴의 이화학적 특성을 조사하였다. 침지조건에 따른 아미노산 함량은 큰 차이가 없었으나 상업적으로 판매되는 돈피나 소가죽 젤라틴과는 그 조성이 달랐다. 이는 원료의 특성과 제조공정의 차이에서 기인하는 것으로 사료된다. 젤라틴의 수율과 젤라틴 겔의 경도는 산성 조건에서 24시간 침지한 경우에, 알칼리 조건에서 1주 침지한 경우에 가장 높다고 평가되었다. 점도와 투명도는 침지기간이 증가함에 따라 산성 조건에서는 증가한 반면 알칼리 조건에서는 감소하였다. 색도는 산처리 닭발 젤라틴 겔이 알칼리처리 젤라팅 겔에 비해 L값은 높고, a값과 b값이 낮아 미관상 더 바람직하다. 이화학적 특성이 우수한 산처리 24시간 침지 시료와 알칼리 처리 1주 침지 시료의 분자량 분포를 Gel permeation chromatography로 살펴본 결과, 두 시료 모두 12개의 획분으로 구성되었다. 가장 많이 발견되는 분자량은 669 kD으로 알칼리 처리 시료가 산처리 시료에 비해 두 배나 많았으며, 300 kD 이하는 산처리 시료가 알칼리 처리군에 비해 현저히 많아 산처리 시료가 알칼리 처리군에 비해 상대적으로 저분자화 되어있었다.

This paper proposes fault tolerant gaits of a quadruped robot with feet of flat shape. Fault tolerant gaits make it possible for a legged robot to continue static walking against a leg failure. In the previous researches, it was assumed that a legged robot had feet that have point contact with the surface. When the robot is endowed with feet having flat shape, fault tolerant gaits can show better performance compared with the former gaits, especially in terms of the stride length and gait stability. In this paper, fault tolerant gaits of a quadruped robot against a locked joint failure are addressed in straight-line motion and crab walking, respectively.

The present study was designed to see what the local cooling of different body regions especially head and neck, hands and feet effect physiological responses in cold environment. Four male subjects wore garments covering whole body except face and rested for 20 min and then they rested for 40 min with uncovered head, neck, hands and feet, respectively in a cold environment(10$\pm$1$^{\circ}C$, 50$\pm$5%R.H.) 1. Rectal temperature increased when hands and feet were exposed to cold environment respectively, and when head and neck, hands and feet were exposed to cold environment together. 2. Exposed skin temperatures fell in cold environment. And hands temperature was lower than any other exposed skin temperatures. The hands temperature was significantly lower when head was exposed than when head was covered. And the feet temperature were significantly lower when hands were exposed than when hands were covered. 3. Mean skin temperature was the lowest when head and neck, hands and feet were exposed simultaneously, In conclusion, skin temperatures of extremities were decreased due to exposure to the cold environment. Especially upper extremities were lower than lower extremities by exposed parts of the body. It seemed that the extremities played the role of cold receptors but head and neck didn't. And there were large heat losses from the unprotected head and neck. In cold environment of 1$0^{\circ}C$ , thus, it is suggested for the purpose of thermoregulatory responses that head and neck would be covered and extremities would be exposed, especially upper extremities.

Hallux valgus deformity has been slowly getting popular in Korea. Many surgical procedures are available for treating the hallux valgus, but it is still controversial for the best treatment. We operated 25 feet(15 patients) of hallux valgus between May. 88 and December. 94. The clinical results were as follow ; 1. Age distribution was 25 to 82, and all female. 10 patients have bilateral hallux valgus. 2. 19 feet were treated by soft tissue procedures only and 6 feet by combined soft tissue and bony procedures. 3. Bunion deformity was recurred in 2 feet (1 Patient) which were treated with modified McBride Method. 4. Lateral sesamoidectomies were performed in 7 feet without development of hallux varus. 5. The cosmetic and functional results were good in 6 cases treated by proximal metatarsal osteotomy. 6. 9 feet had other digits deformities, which need surgical correction. 7. Tightening repair of medial capsule seems to be important for prevention of recurrence of bunion.

This study was conducted to investigate the thermoregulatory characteristics of feet and legs by comparing with the physiological responses according to the covering parts of lower limbs. Five healthy female subjects wore three types of clothing-covered legs and feet(LF-C) with long trousers and socks exposed the legs(L-E) with half trousers and socks and exposed the legs and feet(LF-E) with only half trousers-when the subjects rested at $25^{\circ}C$ and were exposed to 18$^{\circ}C$ for 90 min. Rectal temperatures (Tre) were maintained higher in LF-E than L-E and LF-C at both environments. Decreases of The after exposure to 18$^{\circ}C$ were significantly smaller in LF-E than L-E and LF-C and almost same in L-E and LF-C Heat production in both environments increases of heat production and weight loss after exposure to 18$^{\circ}C$ were not significant among three types of clothing. From these findings it would be suggested that the legs would play the little role of voluntary thermoregulation as vasoconstriction and the role of the legs depend on thermal conditions of feet while the feet play the positive role of voluntary thermoregulation in terms of heat conservation in cool environment.
