  • Toes socks are used widely for the health of feet. However, discomfort is one of the major complains from toes socks users. The purpose of this study is to determine the effect of functional fibers on the physiological response and wearing sensation of toes socks. For experiment, two different toes socks with cotton/warm fiber(WS) and cotton/chitosan fiber(CS) were knitted automatically by a computer controlled flat knitting machine. The control toes socks with cotton/nylon/polyurethan(TS) were prepared to compare the properties. Experiments were conducted in a climate room of $16\pm2^{\circ}C$, $50\pm5%$ R.H. The results of this study were as follows. The change of heart rate, pulse rate, and mean skin temperature showed no difference among three different socks. However, skin temperature of TS was evaluated higher than that of WS and CS. After exercise wearing WS both instep temperature and sole temperature of women tend to higher compared to men. Wet sensation and overall comfort sensation of toes socks were significantly influenced by different fiber contents. Subjects evaluated WS and CS more comfortable than TS.

  • In this study, a robot foot having toes for firm stepping on uneven surface is proposed. The toes are connected to the lower leg by parallel links so that the lower leg can rotate in the rolling and pitching directions during stance phase without ankle joint. The landing performance of the foot on uneven surface was evaluated by relative comparison with that of the most common foot making point contact with the walking surface, since the test conditions considering real uneven surface could be hardly defined for its objective evaluation. Anti-slip margin(ASM) was defined in this study to express the slip resistance of a robot foot when it lands on a projection with half circular-, triangular- or rectangular cross section, assuming that uneven surface consists of projections having these kind of cross sections in different sizes. Based on the ASM analysis, the slip conditions for the two feet were experimentally confirmed. The results showed that the slip resistance of the new foot is not only higher than that of the conventional point contact type foot but also less sensitive to the surface friction coefficient.

  • Painful legs and moving toes (PLMT) syndrome is characterized by spontaneous movements of the digits and pain in one or both lower extremities. Of the reported cases, a majority of the patients was female, and the mean age of onset was 58 years. Only one pediatric case has been reported so far. Herein, we report the first adolescent case of PLMT in Korea. A 16-year-old girl complained of tingling pain in the left leg and involuntary movement of the ipsilateral great toe one month after a second untethering surgery. Three years ago, she had undergone untethering surgery to correct lipomeningomyelocele at the S2 level of the conus medullaris. At that time, she was diagnosed with polyradiculopathy at the left L5 level with axonal involvement. We diagnosed her with PLMT syndrome and prescribed gabapentin. Her symptoms diminished within a day. Complete relief from involuntary movement of the toe was achieved within four months. PLMT is a rare syndrome but it should be considered in the differential diagnosis of children and adolescents with limb pain and spontaneous movement in their toes.

  • This study identifies the foot shapes of elderly men by classifying foot types according to the shapes of sole of foot and analyzing individual characteristics. The subjects were 269 elderly men over 60 years of age. Their right feet were measured indirectly with a 2D scanner. The anthropometric measuring items consisted of 38 items that were estimated on the right foot of each subject. The 2D scan data were analyzed by various statistical methods such as factor analysis, ANOVA and cluster analysis using the statistical program SPSS 19.0. A total of 8 factors were extracted through a factor analysis and these factors represent 77.83% of total variance. The 8 factors were: ball and lateral foot protrusion, ball gradient, medial foot protrusion, anterior and posterior foot length ratio, lateral ball length, heel size, toes breadth, and foot length, that explained 77.83% of the total variance. A total of 4 clusters (as their sole type) were categorized using 8 factor scores by cluster analysis. Type 1 was classified as H-type(toes width, foot width, heel width uniform and medial malleolus and lateral malleolus almost no protrusion). Type 2 was classified as V-type(foot width and toes width, wide and heel width narrow). Type 3 was classified as A-type(foot width and heel width, wide but toes width narrow, protruded inside). Type 4 was classified as D-type(protruded outside).

  • This study was attempted to clarify differences in sizes and shapes of foot between 20's and 60-70's women and analyzed the characteristics of elderly women's foot shapes as compared with those of young. The 2D data were 101 elderly and 101 young women in Seoul and Gyeonggi-do. The results are as follows: Firstly, the foot length of the elderly was shorter than that of the young, the foot breadth and the heel width were widened, but the toes breadth became smaller and the deformity of the toe 1 and the first metatarsal part appeared. Secondly, in the Foot Index, there was a significant difference in age group, the young is more than the elderly in the narrow type, standard type, the elderly women showed more than three times the young in the wide type. Thirdly, in the factor analysis for the foot type classification, 'foot length' factors in both age groups were large. Next, young group were influenced by 'toes breadth', lateral ball breadth' factors, elderly group was influenced by the 'lateral ball breadth', 'medial ball breadth' factors. Lastly, in the cluster analysis of the elderly group, the types of sole were classified as W-Type(20.8%, wide foot and toes, large heel), H-type(20.8%, small toes breadth, heel), D-type(31.7%, long length and wide lateral ball) and A-Type(26.7%, which is found only in the elderly, small length and large toes angle). As a result, it is necessary to design the shoes that match the characteristics of the soles of the elderly women.

  • The purpose of this study was to present the clinical analysis of the results of lateral arm free flap for small sized and infected diabetic foot ulcer around toes. From May 2006 to December 2007, Seven patients were included in our study. Average age was 52.8 years, six were males and one was female. All had infected diabetic foot ulcer and had exposures of bone or tendon structures. Ulcers were located around great toe in four patients, 4th toe in one and 5th toe in two. Three patients had osteomyelitis of metatarsal or phalanx. After appropriate control of infection by serial wound debridement and intravenous antibiotics, lateral arm flap was applied to cover remained soft tissue defects. Posterior radial collateral artery of lateral arm flap was reanastomosed to dorsalis pedis artery of recipient foot by end to side technique in all cases in order to preserve already compromised artery of diabetic foot. All flaps were designed over lateral epicondyle to get longer pedicle and averaged pedicle length was 8 cm. Two cases were used as a sensate flap to achieve protective sensation of foot. All flaps survived and provided satisfactory coverage of soft tissue defects on diabetc foot ulcers. All patients could achieve full weight-bearing ambulation. No patients has had recurrence of infection, ulceration and further toe amputations. There were three complications, a delayed wound healing of flap with surrounding tissue, a partial peripheral loss of flap and a numbness of forearm below donor site. All patients were satisfied with their clinical results, especially preserving their toes and could return to the previous activity levels. Lateral arm free flap could be recommend for infected diabetic foot ulcers around toes, to preserve toes, coverage of soft tissue defect and control of infection with low donor site morbidity.

  • More than 1,000 chickens of Korean native Yeonsan Ogolgye (Natural Monument No. 256) were used in this study in order to investigate their various external characteristics. The aims of this study were to define the Ogolgye chicken as a breed, and to provide basal data necessary for the genetic improvement of this breed. The investigated items are as follows : color of feather and toe; presense or absence of shank feather; the number of toes: color of shank and comb; the growth rates of shank, comb and feathers in various feather tracts; and finally, the livability. Data and informations were presented in tabular form in table 1 through 12. In summary, the various external traits of the Korean native Ogolgye breed can be characterized as follows. It has normal feather than silkic one as in the western type, with black color per-dominant. The frquency of white feather color is very low. The color of toes is devided into two categories; black toes in black plumage lines, and white toes in white plumage lines. Both seres have single combs with black color. The shank is gray- black and featherless. The breed has normally four toes. The eye color is black.

  • Purpose: Reconstruction of small defects of the dorsal fingers and toes is a challenging task. Although adipofascial flap is widely used for these areas, additional refinements are warranted. In this paper, we define the appropriate defect size in the finger and toes that can be treated with the adipofascial flap, refine its surgical indications and present a few surgical tips. Materials and Methods: Twelve patients with dorsal defects of the fingers and toes were treated with a random-type adipofascial turn-over flap and skin graft. If the defect area exceeded the size that could be covered by a conventional design, the flap base was designed in oblique or curvilinear fashion to lengthen the flap. For accurate defect coverage, the width of the flap base was designed in an asymmetrical shape depending on the defect configuration, varying the width from 0.3 to 1.0 cm, as opposed to the standard 0.5 to 1.0 cm width. Moreover, the lateral limit of the flap was defined as the lateral axial line. The size of the defect ranged from $3.0{\times}1.7cm$ to $1.5{\times}1.3cm$. Results: All flaps survived completely. Gliding function of the hand was well preserved and there was no evidence of tendon adhesion. Conclusion: The small defect in the dorsal finger and toe can be defined as less than one phalanx-length, measuring about $3.0{\times}2.0cm$ in size. If the defect exceeds this dimension, it is recommended that a different option be considered. We believe the adipofascial flap is an excellent option for treating small defects.
