The purpose of this study Is to classify foot types of elderly women and young women and to suggest shoes size system by foot types for elderly women. The subjects were 321 elderly women and 181 young women. Their right feet were measured directly and indirectly by using scanner and digital camera. The anthropometric measurements were composed of 62 items. They were measured during the months of July and October in 2001 and November in 2002 The results and discussions of this study are as follows. First, in analyzing shape of the foot of elderly and young women, the shapes of foot were classified as N-type (high and narrow foot shape and wide toes), W-type (wider width for its length and severe alteration), L-type (low foot shape as oval). Second, the most characteristic foot 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. On the other hand, young women belonged to N-type. Third, we suggested new size system of shoes for elderly women and the standard foot shape each type. The size system was based on foot length and foot types. Hopefully, understanding the shapes of foot and characteristics of each foot type will help to develop suitable shoes for elderly women.

In the study, the fatigue strength improvement and mechanism have been estimated by the Spot-Heating treatment on welded bead toes. For this, web-gusset specimens were made without residual stresses and the others with residual stresses imposed by Spot-Heating. The 4-point bending tests were performed in order to estimate the effect of spot-heating on fatigue strength and fatigue characteristics quantitatively for non load-carrying fillet welded joints subjected to pure bending. As a result of fatigue test, fatigue strength of As-Welded specimen for non load-carrying fillet welded joints subjected to pure bending has satisfied the grade of fatigue prescribed in specifications of korea, AASHTO and JSSC. As compare with As-Welded specimen and Spot-Heating specimen have increased about 20% for the fatigue strength at $7.7{\times}10^6$ cycles. The Spot-Heating by reformation of the residual stress on welded bead toes has greatly affected the fatigue crack propagation life, but has slightly affected the fatigue crack initiation life.

Purpose: This study examined that effect of a change in balance index on ankle Kinesio taping, muscle strength exercises and taping after muscle strength exercises in 30 healthy adult subjects. Methods: The Sway Index of the left, right, front and back on stable, toes up and linear were compared using a Balance System, a balance experimental instrument. Results: The pre and post experimental balance index regarding stable, toes up, and linear were taken for the Kinesio taping group, lower extremities muscle strengthening group, and muscle strengthening with the Kinesio taping group. Statistically significant decreases were observed in all variables except for the left and right pre and post experiment results under stable conditions. Conclusion: The balance index of exercise with taping was lower than that of exercise only. There is a need for objective research on the long-term applications and post-exercise. The body balance appears to be influenced by ankle stabilization using taping.

Background : The Purposes of this study were to understand difference between free walking and obstacle over walking through the naked eye and motion analysis device, and to review merits of obstacle walking training as item of functional assessment in clinical situations. Methods : All participants were male and performed 3 types of walking methods: free walking, obstacle over walking with low block(height=10cm, width=8cm), and obstacle over walking with high block(height=20cm, width=8cm). All walking were performed 3 trials respectively. Results : In the naked eye, initial contact with toes occurred more than heel strike in obstacle over walking, and the flexion angle of hip and knee were increased in obstacle over walking. On interpretations though motion analysis device, cadence, gait speed and weight accept were significant statistically(p<.05). Cadence and gait speed were decreased, and weight accept duration was increased in obstacle over walking. Rotation among three pelvic motions was significant statistically(p<.05), flexion among three hip motions was significant statistically(p<.05) and flexion among three ankle motions was significant statistically(p<.05). Rotation and flexion among three ankle motions was significant statistically(p<.05). Conclusion : Both the naked eye and interpretations of the device presented many difference between free walking and obstacle over walking. In overcrossing obstacles, many participants appeared walking strategy by perform initial contact with toes. Knee flexion was most significant statistically(p<.05) in obstacle over walking with 20cm block.

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

In this study, three lecanid rotifer species were newly recorded in Korea: Lecane inermis (Bryce, 1892), L. furcata (Murray, 1913), and L. nana (Murray, 1913). Most of the lecanid rotifers recorded in Korea have been collected from stagnant water, and Lecane furcata and L. nana were collected from a reservoir. In contrast, L. inermis was found in a soil sample. Lecane inermis is the first illoricated lecanid species reported in Korea. This species is distinguished from other illoricated species by its toes with relatively long claws. Lecane furcata is the most common lecanid rotifer in submerged vegetation. The morphological characteristics of its lorica are similar to many other lecanid rotifers, but it can be distinguished by its completely fused toes with a terminal fissure, an absence of antero-lateral spines, and the ratio of lorica/toe length. Lecane nana is most similar to L. tryphema Harring & Myers, 1926, but can be distinguished by the toe tips curved outwards. The three species in this study are considered to have a cosmopolitan distribution and have been recorded in many Asian countries. In this paper, we describe the morphological characteristics of the three lecanid species with trophi structures observed by scanning electron microscope.

The Say-Barber-Biesecker-Young-Simpson variant of Ohdo syndrome (SBBYSS) (Online Mendelian Inheritance in Man #603736) is a rare autosomal dominant disorder and clinically features blepharophimosis with ptosis, a mask-like facial appearance, cryptorchidism, congenital heart defect, long thumbs/great toes, and thyroid dysfunction. The etiology of SBBYSS has been shown to be due to heterozygous KAT6B gene mutation. Here we report a case of a neonate with SBBYSS identified a novel mutation in KAT6B gene. The patient showed typical dysmorphic facies, cryptorchidism with micropenis, overriding fingers, and long thumbs and toes at birth. He had also hypothyroidism, large atrial septal defect, and sensorineural hearing loss. The next generation sequencing identified a heterozygous novel variant, c.5206C>T (p.Gln1736Ter) in KAT6B gene. At the 9 months of age, he underwent patch closure for atrial septal defect. Until the 12-month follow-up, he was under-developed.

Periosteal chondroma is a rare, slow-growing, benign cartilaginous tumor that develops between the periosteum and cortex, but there are no reports of multiple periosteal chondroma of the toes. A 19-year-old male presented with a palpable mass of the right fourth toe with tenderness for one year. A radiology examination revealed multiple, radio-lucent lesions with mild cortical irregularity. The magnetic resonance imaging findings were chondrogenic tumors with multiple, well-defined T1-low and T2-high signal enhanced lesions involved in the fourth proximal, middle, and distal phalanges. The tumors were removed by a surgical resection and curettage. Histologically, the tumors were proven to be periosteal chondroma.

The Sample was consist of 216 female adults who were selected with my convenience from residing women in and around Seoul, Korea. The result were as fellowing; According to the factor analysis of their foot discomfort, it is divided into 3 factors: the discomfort of whole body (factor 1), the discomfort of foot sole (factor 2), and the discomfort of toes (factor 3). And the foot part of discomfort is more frequent in the order of the big toe, 2·3 metatarsal bones, and the little toe. As the age gets older, the discomfort of foot sole and toes are reported more frequently, and, particularly, more student and office employees have the discomfort of whole body while more sales women and housewives have the discomfort of foot sole. In terms of the shoe types, the higher the hill height, the more the discomfort of foot sole with wearing the sharp toe. As the wearing time is longer, the discomfort of foot sole increases. Being related to the from patterns, the broad and short type has more of the discomfort of foot sole, the flat foot feel more discomfort from the entire body and the sole. Walking with leaning toward the frontal the discomfort on toes and sole increases.
