  • 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.

  • This study analyzes the characteristics by age and type for middle aged and elderly women foot shapes aged 40-69 years. ANOVA, factor, and cluster analyzed middle aged and elderly women's foot shapes. The results of the study are as follows. First, higher age groups tended to have smaller foot lengths, ball/instep circumferences, circumferences, and ball heights with larger heel height values and higher degrees of gathering of toe 1 and toe 5 toward the feet reference axis. Second, foot lengths were 220 mm-240 mm and the ball circumference's size symbol in high frequency sections were distributed from E to EEEE in the 40s and 60s groups and from D to EEEE in the 50s group. Third, eight factors were extracted through the factor analyses of middle aged and elderly women's foot measurement items. Fourth, a cluster analyses classified the subjects into four types. Type 1 is a normal foot type with medium foot length and small ball circumference and type 2 is a long and flat foot type with a type with large foot length and ball circumference values as well as small ball height values. Type 3 is a thick foot type with a medium foot length, large ball circumference, large ball height and type 4 is a toe deformation foot type with medium foot length, small ball circumference, and a high degree of toe gathering toward the center.

  • This paper presents a cost-effective 3D foot scanner system that provides the 3-dimensional point cloud foot data to design the custom footwear. To measure the 3-dimensional point cloud data of the foot, a CCD camera, a Non-Gaussian laser line projector and optical triangulation method are employed. Furthermore, the integrated system employs a measurement base, a frame grabber, a CCD moving cart, a stepping motor and a computer. The measurement result is saved as 3D dxf format and it could be converted to 2D essential data fer a shoe design. The experimental results demonstrate that the proposed system have the decent resolution of 1mm which is enough for last and shoe design.

  • This study aims to define the isochronism of English feet. 275 feet, which consist of 66 lines of 13 poems written by 12 modem poets(The Poet Speaks, 1982), were used for analysis of durational measurement. To assess the average value of a foot, the study is, first, to set up a way of measuring the duration of each foot on its types in English meter. Secondly, with the measurement of the average duration of feet in modern poets' English poetries through Praat (version 4.119, 2003), it clarifies the foot isochronism in the fixed meter. With the two ways of measuring the isochronism, it clarifies the fact the foot isochronism permits the difference scope of the perceptive gap of 555.4-974.5msec. per foot in case of iambic meters in English poetry.

  • The purpose of this study were to analyze the anthropometric data of feet of Korean women with aging, to categorize the women's foot shapes, and to compare the shoe size according to the foot shapes in order to provide the basic information for more comfortable shoes. Subjects of this study were 181 women over age 20. They were measured with the direct measurement method and the indirect measurement method. 26 items were measured from the right foot and 6 items were taken on foot outline. Factor analysis, cluster analysis, analysis of variance, post-hoc test, and cross tabs were peformed for statistical analysis of the data by SPSS program. There were significant differences in height items, breadth items, girth items, and angle items by subjects' age. The older subjects' feet were wide and thick with big deformity on toes. The arch height of the older ones was low. This implicates that the degree of deformity on toes, the foot ratio, the foot girth, the foot breath and the arch height as well as the foot length are needed to be considered in developing comfortable shoes. Nine foot construction factors were extracted by the factor analysis of anthropometric measurements; foot size factor, heel and instep factor, malleolus lateralis factor, malleolus medialis factor, foot shape factor, shape of toes factor, heel height factor, big toe height factor, and internal factor. On the basis of the cluster analysis, three different foot shapes were categorized. Type 1 was large and wide foot with little deformity on little toe. Type 2 was medium foot with deformation of big toe, and with the lowest arch height. Type 3 was small and narrow foot with the highest arch height. Distribution of shoe size according to the foot shape was analyzed. The ball of foot breath was of wide distribution than the ball of foot girth. This implicates that girth items and breath items of the foot should be enclosed for the same foot length in the shoe sizing system.

  • The design of foot-bridge is often influenced by natural frequency. Consequently, vibration frequency becomes important. The empirical expressions used to quantify this parameter at the design phase have not been developed enough to give guideline to Korean foot-bridge. This paper is concerned with the vertical natural frequency of steel foot-bridges. It describes the vibration measurement methods employed for testing structures and presents reliable methods of assessing natural frequency from jumping vibration tests. Data from measurements on 16 structures in Seoul are given. Regression formulas of natural frequency for steel-framed foot-bridges are suggested. Finally, obtained formula are compared with empirical expressions of Seoul City's guideline.

  • PURPOSE: Despite the abundant literature available regarding the activity of intrinsic muscles, few studies have investigated the muscle activity of extrinsic muscles. Therefore, the present study compared the muscle activity of the peroneus longus, tibialis anterior, and abductor hallucis during short foot exercise in subjects with and without flat feet. METHODS: Twelve subjects with and without pes planus participated in this study. During the short foot exercises, muscular activity of the tibialis anterior, fibularis longus, and abductor hallucis longus were measured in both groups. To identify the effects of short foot exercises, navicular drop height was also investigated in pre and post short foot exercises. RESULTS: In a symptomatic group, the navicular drop height was significantly reduced at post measurement compared with pre-measurement. During the short foot exercise, the pes planus group showed significantly lower activities of the fibularis longus than the control group (p<.05). CONCLUSION: Similar to previous studies and clinical literature, short foot exercise was effective for alleviating navicular drop for a population with pes planus. In addition, subjects with pes planus showed decreased muscular activities of the fibularis longus, which suggests that considering extrinsic muscles such as fibularis longus is also important for rehabilitation of pes planus patients.

  • Unrestricted measurement method of three-dimensional walking distance utilizing body acceleration and terrestrial magnetism is discussed. The three-dimensional walking distance is derived by the integration of the three dimensional acceleration of foot during swing phase. Since the sensor system attached on the foot rotates during swing phase, the acceleration data measured on the foot include acceleration of gravity which causes inaccurate calculation of the velocity and the distance. Three gyros are used to compensate the rotation of the sensor system. Moreover, one geomagnetic sensor is employed to derive the heading direction of the subject Healthy volunteers performed ...

  • The foot shape from the right and left feet was taken with 78 male and 213 female Korean subjects. The results are as follows. 1) Mean values and standard deviations of 25items concering the foot : Measurements performed on Korean adults(male and female) show that male left foot length is in average somewhat longer than the corresponding right foot length(25.35Cm against 25.32Cm) and on the contrary that the circumference of the left foot is slightly smaller than for the right foot. For the same tendency is verified in female feet. 2) Correlations between measurement items : Finding a correlation of more than 0.08 only between the foot length to suggest that the present system of ready-made "shoe" size system, based only on foot length, is not a quite appropriate system. 3) Distribution between foot width, foot girth, instep height and foot length : Foot length showed from 21.52Cm to 24.0Cm in the female subjects and from 24.0Cm to 26.5Cm in the male subjects for the standard type. Foot width showed from 7.5Cm to 10.0Cm in female and from 8.5Cm to 10.5Cm in male for the standard type.dard type.
