The physico-chemical properties of fresh milt of marbled sole, Limanda yokohamae, brown sole, Limanda herzensteini, starry flounder, Platichthys stellatus and olive flounder, Paralichthys olivaceus among flatfishes, and the fine structure of their cryopresserved spermatozoa were investigated. The highest concentration of sperm among these four species was $3.60\pm1.35\times10^{10}/mL$ in marbled sole. Osmolality and pH of seminal plasma in four flatfish species were approximately 330 mOsm/kg and 7.6-8.1, respectively. Seminal plasma compositions showed interspecific differences. The sperm heads of marbled sole, brown sole and starry flounder were ellipsoidal and that of olive flounder was round. The numbers of mitochondria of these four species were eight in marbled sole, seven in brown sole and starry flounder, and six in olive flounder. Cross-sectional view of flagellum showed typical 9+ 2 structure in all species. Most of sperms cryopreserved with a proper method had no visible ultrastructural changes after freeze-thawing, compared with the fresh sperm, but in a few cases, swelling of their heads and midpiece regions were observed.

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.

Even though many researchers studied the foot shape and dimension, those applications lacked. The purpose of this study was to develop insole pattern of elderly women according to footprint. Discrepancy in the classification criteria among of foot parameters complicates attempts for elderly women classification of foot sole. To develop a footprint-based classification technique for the classification of foot sole types by allowing simultaneous use of several parameters. Foot sole data from static standing footprints were recorded from 48 elderly women. The factors of footprint shape were determined. Cluster analysis was applied to obtain individual foot sole classifications. The classification model of foot insole is proposed for a classification of footprint in elderly women. An application of ANOVA, Duncan's analysis, frequency analysis, factor analysis, and cluster analysis have been made to footprint data. In order to make clear foot sole characteristics, the factors of footprint shape have been discussed. The results are as follows. The factors of footprint shape have been classified into four types: foot length, sole slope, outside sole slope, and foot width. The types of foot sole shape have been classified into four types: longed, shortened, outside sloped, and toes sloped.

Postburn scar contracture of sole can cause musculoskeletal deformity, restricted range of motion, and decreased quality of life. It is very important to exhibit similar characteristics of the sole when reconstructing the sole because it has to resist shearing force and weight bearing. In this case, we performed medialis pedis free flap for the postburn scar contracture of the sole and the flap survived without complication. The patient satisfied with functional and aesthetic outcomes. Medialis pedis free flap, which is harvested adjacent to the sole, can show similar characteristic of the sole and maintain adequate contour. Moreover, this flap can be harvested without sacrifice of major vessel or nerve. Due to these advantages, medialis pedis free flap can be an ideal option for the reconstruction of the sole.

This study classified the type of sole for female high school students and analyzed the characteristics of each type by the shape of the sole (plantar view) using 2D scan data. The data were collected from a foot anthropometry of 310 female high school students in Gwangju and Jeollanam-do. Left feet and right feet were measured indirectly by using flatbed scanner. The sole anthropometric measurements consisted of 24 items. The results of the investigation into the differences between left and right feet soles by the 2D measurements data indicated that there was no significant statistical differences in the length of items. The left sole had higher values than right sole in the width items and angle items; however, the lateral side of the right feet projected to the outside more often than left feet. In analyzing foot sole of female high school students, the shapes of sole were classified into three types. Type 1(41.94%), Type 2(36.77%), Type 3(21.29%). The most characteristic sole type for female high school students was Type 1. Type 1 referred to a narrow foot width with little or no curvature of the toe. Type 2 represented the longest foot, with foot width shown as a spacious and distinctive feature in width at the medial area of the foot. Type 3 represented the shortest and widest of ball width, gathered inside toe 5, and lateral side as the most projected among the three types.

The proper conditions for cold storage of milt in four species of flatfish were investigated. Various diluents were tested for the preservation of marbled sole, brown sole, starry flounder and olive flounder milt at $1\pm0.5^{\circ}C$ for 7 days. The most effective diluent was $1\%$ NaCl for marbled sole and Stein's extender for brown sole, starry flounder and olive flounder. After 7 days of storage in different dilution ratios (milt: diluent), marbled sole milt diluted with 1:3-10 and brown sole, starry flounder and olive flounder milt diluted 1:1-10 maintained good sperm activity index (SAI). SAI was affected by storage volume and presence of antibiotic. SAI was lower after 7 days storage in the volume of 1.5 mL than in 0.5 or 1.0 mL. SAI after 29 days storage was markedly enhanced by addition of antibiotic in marbled sole (400 ppm gentamicin, 400 ppm neomycin, 200-400 ppm streptomycin), brown sole (600 ppm gentamicin), starry flounder (1,000 ppm gentamicin) and olive flounder (200-1,000 ppm gentamicin, 200-400 ppm neomycin, 200-1,000 ppm streptomycin).

The purpose of this study is to identify foot shapes of elderly women by classifying their foot types according to the shapes of sole (plantar view) of foot and analyzing the characteristics of each type. The subjects were 321 elderly women over 60 years of age. Their right feet were measured indirectly by using .scanner. The anthropometric measurements consist of 32 items. They were measured during the months of July and August in 2001. The results and discussions of this study are as follows. First, in analyzing sole of the foot of elderly women, the shapes of sole were classified as W-type (wider width for its length and severe alteration), A-type (similar to W-type but with narrower width), D-type (protruded outside) and H-type (even foot width). Second, the most characteristic sole type in elderly women was W-type. In this type, the width was wider for its length, the first metatarsophalangeal protrusion was severe and the toes were gathered at the center. Hopefully, understanding the shapes of sole and characteristics of each sole type will help to develop suitable shoes for elderly women.

We have investigated the clinical results of 33 cases of free flap transfer performed for the soft tissue defects of heel and sole. In donor sites, tensor fascia lata flaps were 4, dorsalis pedis flaps were 10, forearm flaps were 9, and latissimus dorsi flaps were 10. The recipient sites were heel in 22 cases, sole in 7 cases, and heel and sole in 4 cases. In these cases, the postoperative complications, morbidity of donor sites, recovery of sensation, and cosmetic results were evaluated in each flap. All the flaps survived successfully. The free flaps provided excellent functional and cosmetic results. The tensor fascia lata flap was more reliable free flap for the reconstruction of heel and sole defects.
