For the purpose of investigating the factor of foot and calf growth of primary-school children who are fastgrowing during this period, a group of the 1st graders of primary-school had been the subject of this measurement in 1995 and thereafter they became the subject again in 1997 when they were the 3rd graders. Measurement was carried out in 30 items including height and weight and marthin-type measurer and Footprint were used for this measurement. As the result, in the part of calf, the measuring items of maximum calf circumference and knee circumference, and in the part of foot, the items of instep circumference, heel circumference, instep circumference, measured angle of big toe showed the highest growth. The average growth of length for 2 years appeared about 2cm and the parts of instep circumference, heel circumference had rapidly grown rather than in the part of foot circumference. Height growth of the part of toe was about 0.1 and in the factor analysis of foot measurement of 8-year and 10-year and children, the following findings appeared in both cases that height was related with the items of calf height and foot length and weight was related with calf circumference and breadth, foot circumference items.

For design of early childhood children's footwear, this study was to analyze the properties of their foot. This study was performed in 200 male and 200 female early childhood children from 3 and 6 years old lived in susan urban area. There were measured 17 items of the foot and calculated 4 indexs for analysis. The result was as follows; 1 The growth rate differs from the sites of a foot. According to the growth of age, early childhood children's foot are more slender. 2. The average of foot print angle is $15~27^{\circ}$ and it is flat. Among the age groups, the numbers of 4 kinds of foot print angle are different siginificantly. 3. The average of metatarso phalanx angle is $174~178^{\circ}$ that is higher than adults'. 4. There are no significant difference between male children's foot and female childen's one except tarsal circumference and tarsal height. Tarsal part of male children is higher and ticket than female children's. 5. Because some of 3~6 age groups belong to the one foot length group, we should consider the age properties of foot in order to design footwears. When the size of footwear is divided by only foot length, the ranges of another measurements are larger than the range of foot length.

This study was performed to provide the analysis on their size and the structural factors required in the process of design and manufacture of school girls' shoes. 371 elementary school girls in Kyungin and Youngnam area were participated in the size measurement. 25 foot items and 6 main body items were measured directly or indirectly using a digital photography. The results of the study are as follows: first, by most of measured items, the range of their foot size was very wide from the size of toddlers to adults'. That shows that the change of school girls' foot size occurred with their growth is pretty big. Second, from the structural factor analysis on 25 foot items, five factors were extracted such as 'the size of the foot', 'the volume of the foot,' 'the height and inclination of the foot,' 'the shape of the foot,' and 'the inside and outside inclination of the foot'. Third, from the cluster analysis, three clusters were classified: Cluster 1 was the group of 10 to 11 year old girls who had big-sized feet. The elementary school girls in the fourth to sixth grade belonged to this group. Cluster 2 consisted of girls who had small-sized and big-volumed feet. Cluster 3 had medium-sized and slim-shaped feet. Most of 6 to 7 year old elementary school girls belonged to this group. The above-mentioned results imply that many continual researches are required on children's shoe production reflecting the change of elementary school girls' feet size owing to their growth. The quantitative data on elementary school girls' feet size in this study could be used as basic information for the development of children's shoe design and its production.

This study aims to categorize age groups for shoes manufacturing including shoes size and boot tree development for Koreans. In order to carry out the research, the characteristics of different parts of foot in relation to size are analyzed according to age and sex, making use of human body measurement database. As a result of statistical analysis, it was found that the measurement items such as foot length, metatarsal tibiale, foot breadth and instep circumference of a person reached the range of standard deviation and average numerical figures of an adult group (18-24) from the age of 14 in men's case, and from 12 for women's case, which indicates the time of completion of their foot growth. Based on these findings where males of 14 years old and females of 12 are within similar measurement range to adults, it is necessary to categorize the age groups for shoe sizing system into the following four groups: males 13 years old or under, males 14 years old or over, females 11 years or under, and females 12 years or over. The proportional measurement produced by dividing each measurement item of foot parts by foot length was compared in an independent samples t-test, and there were meaningful differences according to different foot shapes of the two age groups of males 13 or under - males 14 or over, and females 11 or under - females 12 or over. Also, the independent samples t-test for the age groups of males 13 or under - females 11 or under, and males 14 or over - female 12 or over, showed similar meaningful differences, which indicates the differences in foot shapes of male and female during the period of growth.

Rapid increase in population growth has made the mankind to delve in appropriate identification of individuals through biometrics. Foot Print Recognition System is a new challenging area involved in the Personal recognition that is easy to capture and distinctive. Foot Print has its own dimensions, different in many ways and can be distinguished from one another. The main objective is to provide a novel efficient automated system Segmentation using Foot Print based on structural relations among the features in order to overcome the existing manual method. This system comprises of various statistical computations of various foot print parameters for identifying the factors like Instep-Foot Index, Ball-Foot Index, Heel- Index, Toe- Index etc. The input is naked footprint and the output result to an efficient segmentation system thereby leading to time complexity.

This is a tentative study to provide prototype of sizing system for children's shoes. For this study, 364 elementary school girls from KyungIn and YeongNam areas were participated in the measurement. The results of the analysis on four measurement items related to foot can be summarized as followings: 1. All of the foot related items were increased according to their growth. Especially, foot length, foot width, and toe width showed a high correlation. 2. The result also revealed that the current sizing system can cover only 70.9% of children in measurement, which means that a new sizing system is required. 3. We suggested a new standard size for foot size/foot circumference based on the results above according to current sizing system, and a new standard size for foot circumference/foot width based on ISO standard. The results of this study would be helpful in the design of sizing system of children's shoe if applied with the raw data of the Size Korea recently measured.

Of 16 million diabetic patients in the USA, 2.4 millions have experienced diabetic foot ulcer and 67,000 have amputations every year. For treatment of diabetic foot ulcer, Americans spend more than $1 billion each year, including $36,000 per patient for complete treatment and $60,000 for each amputation. Neuropathy and ischemia, two common complications of diabetes mellitus, are the primary underlying risk factors for development of diabetic foot ulcers. Ischemic ulcers develop as a result of low perfusion pressure in the foot with inadequate blood supply, whereas neuropathic ulcers develop from loss of protective sensation. In addition, diabetes also increases the risk of infection by impairing the body's ability to eliminate bacteria. From these circumstances, results are chronic wounds with impaired healing ability.

Purpose: The infected diabetic foot patients were reviewed to analyze the result of new dressing methods using a wall-suction instruments. Materials and Methods: Eighteen patients treated with wall-suction assisted vacuum dressing were included. After debridement under local anesthesia, a sponge pad, a drain, and a surgical drape were used to seal the wound. Negative pressure applied by the wall-suction at around 200 mmHg and dressing were repeated in every two to three days. The results of repeated wound cultures, growth of granulation tissues, and CRP level were closely observed on the regular basis. Results: Rapid growth of granulation tissues was noticed around the wound in 16 cases. No organism was obtained in an average 5 days and wound coverage was possible in an average 18 days. The CRP level returned to normal in an average 4 weeks. Two patients with end stage renal disease, who were regularly hemodialised, underwent major amputation. Conclusion: New dressing method has the following advantages: a rapid wound improvement in the patients with infected diabetic foot, less expensive, less painful, impediment of bacterial contamination in the hospital room. However, further study will be needed for the end stage renal disease patients.
