The present study is intended to study sole types necessary for shoe designs for elementary school students that are in age groups in growth periods, and 3D midsole design utilizing 3D printing technology. This study analyzed data from the 3D measurement of the feet of 1,227 elementary school students aged 7-13 years residing in the capital region conducted as part of the 6th Anthropometry of Size Korea. In addition, 3D midsoles by sole type were designed utilizing a Rhino CAD, and midsole prototypes were output utilizing a Zortrax-M200 3D Printer. Through a cluster analysis of sole shapes by type, sole shapes were classified into three types. Type 1 has small values of foot lengths and foot breadths, with large toe 1 angles and high arch heights. Type 2 has intermediate values of foot lengths and foot breadths, with small toe 1 angles and high arch heights. Type 3 has large values of foot lengths and foot breadths with small toe 1 angles and low arch heights. On reviewing the results of design of 3D midsoles by sole type, it can be seen that the midsoles were designed according to characteristics by sole type. The results of the sole type analysis in the present study are expected to be meaningful as basic data for the development of shoe insoles for elementary school students.

It is considered that the application of advanced composite materials to the prostheses for the disables is important to improve their bio-mechanical performance. Particularly, energy storing foot prosthesis is mostly important to restore gait ability of the disables with low-extremity amputation since it could provide propulsion at terminal stance enhancing the disables ability to walk long distance even run and jump. Therefore, the energy storing spring of Prosthetic foot keel under cyclic bending moment use mainly of high strength glass fiber reinforced plastic. The main objective of this study was to evaluate the stacking sequence effect using the delamination growth rate(dA$_{D}$/dN) of energy storing spring in glass fiber reinforced plastic under cyclic bending moment. The test results indicated that the shape of delamination zone depends on stacking sequence in GFRP laminates. Delamination area(A$_{D}$) turns out that variable types with the contour increased non-linearly toward the damage zones.nes.

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

Populus alba x glandulosa shows greater growth performance in the lower part of the hill than in the upper part. In order to study this reason, correlation between the soil factors and the growth was examined. The results were as follows. 1. Annual mean height growth was 1.29m in foot hill but 0.7m in upper part, showing 184$\%$ better growth in the foot hill than in the upper part and the similar situation was shown in the diameter growth. The longer slope distance, the better growth: generally the good growth shows in the first harf of the distance. 2. High positive correlation shows between the growth performance and soil moisture: r=0.76 in the hight and r=0.71 in the diameter, and also positive correlation between soil depth and the growth performance. r=0.65 in the height and r=0.79 in the diameter. On the other hand, negative correlation between the slope and soil depth are considered as limiting factors to the growth. 3. A significant correlation appeared between growth performance and organic matter and between the growth performance and total nitrogen as well. This shows that the nutrient elements were contained much in the foot hill. 4. The correlation between the height growth and potassium, and between the growth and calcium and pH were shown . 5. However, no correlation was shown between the growth and available phosphate, magnesium and available managanese .

Purpose: The purpose of this study was to introduce the 'Matrixplasty' for the treatment of a severely incurved toenail with growth plate deformity and to report our results treating this disease entity. Materials and Methods: Between January 2010 and May 2010, 48 consecutive patients (62 cases) underwent treatment of symptomatic incurved toenails with the 'matrixplasty'. The mean period of time at last follow-up was $14.0{\pm}1.3$ months. The recurrence rate and complication rate were evaluated. An American Orthopedic Foot and Ankle Society (AOFAS) forefoot hallux score was assigned and patients were evaluated at pretreatment and the last follow-up meeting. For evaluation of improvement in toenail shape, the center to edge angle of the toenail was measured at pretreatment and last follow-up. Results: All ingrown toenails healed and the nail deformity was corrected within 3 weeks after the procedure. Among the 62 cases, four cases had recurred by the last follow-up. The mean pretreatment AOFAS forefoot hallux score was $73.1{\pm}12.8$, and it improved to $98.7{\pm}1.1$ by the last follow-up (p<0.01). The mean center to edge angle of the toenail improved from $53.3{\pm}12.9$ degrees to $18.2{\pm}7.4$ degrees by the last follow-up (p<0.01). Minor paronychia, which was managed with local wound dressing and oral antibiotics, was identified in eight cases. Conclusion: Matrixplasty showed excellent clinical results in the treatment of severe incurved toenail (pincer nail) and this procedure also showed great improvement of the deformed toenail and its growth plate.

Purpose: To evaluate correlation between the clinical results and causative bacteria in diabetic foot patients with lower extremity amputation. Materials and Methods: One hundred twenty nine patients(131 feet) of diabetic foot amputations were followed for more than one year. Wound cultures were done by deep tissue or bone debris at first visit to our clinics. Retrospective analysis was performed using chart review and interview with the patients. Depending on the culture result, level of amputation, reinfection, duration of treatment, death rate, patient satisfaction and admission dates were evaluated. Results: Microorganisms were confirmed in 114 cases. In the other 17 cases, there were no cultured microorganisms. In bacterial growth group, Methicillin-sensitive Staphylococcus aureus was the most common pathogen and accounted for 34 cases. As other common pathogens, there were Methicillin-resistant Staphylococcus aureus(24 cases) and mixed infection(14 cases). Mortality is no difference in each infected group. Mixed bacterial infected patients have higher reinfection, longer hospital day and duration of treatment, but there is no difference in patients satisfaction and pain at last follow up. Conclusion: The most common pathogen in diabetic foot patients with lower extremity amputation was Methicillin-sensitive Staphylococcus aureus, and mixed bacterial infected patients have higher reinfection rate, longer admission date and duration of treatment than other bacterial infected patients.

Because traumatic tissue damage on hands and feet often lead to loss of function, permanent deformity, prompt and adequate reconstruction is essential. For children, future growth, as well as function and esthetics, must be taken into account. Several techniques have been employed to reconstruct hand and foot dorsum defects of children. However, skin graft and muscle free flap with skin graft cannot prevent contracture and will interfere with normal growth. Fasciocutaneous free flap reduces contracture and enables early physical therapy, decreasing the need for additional surgical intervention. Parascapular flap is particularly suitable because it has reliable pedicle and is relatively thin. There is little functional loss in the donor site, and also simultaneous extensor tendon reconstruction of hand and foot is possible. The disadvantage of this technique is that postoperative defatting is needed to adjust volume. Our department has achieved satisfactory results using this approach, and would like to report 13 cases of hand and foot reconstruction using parascapular flap in patients under the age of 15 (from March, 1998 to May, 2003).

The lateral hoof of right hind limb of a pregnant Masai giraffe was accidentally injured, and its coronet, hoof wall, and sole were detached in a mass. The bleeding was observed from the exposed dermis of the affected foot for several hours, with second scoreof supporting lameness. The bleeding from the digital artery at the exposed dermis was stopped by epinephrine spray and direct pressing. Nitrofurazone ointment was topocally applied for 5 days and sxytetracycline solusion was delivered by a fluid jet in the affected hoof one month. The calf was born 5 months after the avulsion. The horn of the hoof wall was grown from the coronet to sole, and was gradually filled from the heel to the toe. The growth rate and filling rate of the hoof wall were 0.32mm and 0.54mm a day, respectively.

For children with most outdoor activities, wearing appropriate shoes is important to their growth and health. The purpose of this study is to identify characteristics regarding children's feet and to provide beneficial information for an appropriate sizing system of children's shoes. The data of the study were 3D measurements of feet from school boys aged 7-12 of the 6th Anthropometry of Size Korea. This study revealed that the two factors related to the size and height of the feet represent the characteristics of children's feet, unlike adults. As a result of applying the data of this study to the current KS sizing system of the children's shoes, only the foot lengths were within the sizing system. Consequently, the current sizing system requires revisions and supplements to the foot-width and foot-circumference sections.

Many researchers revealed that collagen contribute to maintaining the skin’s elasticity and inhibit wrinkling of skin. Korean native cattle (Hanwoo) bone (leg bone, foot and tail) infusion contains the various inorganic materials, collagen and chondroitin sulfate. All of this, a large quantity of collagen is included in Hanwoo infusion. Therefore, this study emphasized on the effects of collagen in the Hanwoo bone infusion. For the first time, Hanwoo bone infusions were directly added to the media of Human Dermal Fibroblast (NHDF-c) to test anti-aging effects. First, it was identified that growth rate of skin fibroblast was increased. Furthermore, the Hanwoo bone infusion increased a 50% of fibroblast collagen synthesis. Also, suppression of skin fibroblast aging was confirmed by treatment Hanwoo bone infusion. In conclusion, this study demonstrates the effects of infusion made from Hanwoo leg bone, foot and tail on anti-aging, wrinkle inhibiting and skin fibroblast elasticity maintaining. Therefore, this study identified that traditional infusion has effects that are good for skin elasticity.
