Objective: The aim of this study is to identify foot shapes of Korean male farmers by classifying their foot types using 3D scan data and analyzing the characteristics of each type. Background: The increasing demands for anthropometric information for the design of machinery and personal protective equipment to prevent occupational injuries has necessitated an understanding of the anthropometric differences to be found among occupations. Static stooped posture and squatting posture are so common in Korean farmers that anthropometric deformation in foot especially seems to occur easily. Method: 366 Korean male farmers volunteered for this study from 16 different farming villages nationwide from 2009 to 2011. Subjects were categorized into 4 age groups from 40s to 70s. Their right feet were measured by using 3D foot scanner, the anthropometric dimensions were composed of 40 items. Results: The 8 major factors affecting the foot shapes were extracted. From these factors the foot shape of Korean male farmers was classified into 3 Foot types. Foot type 1 showed severe deformation in toe 1, type 2 had a narrow shape and type 3 had a wider width for its length. Conclusion: There were some differences in foot shape and types between farmers and the public. The most characteristic foot type in Korean male farmers was type 3. Application: The results of identifying foot shapes of Korean male farmers might provide the useful information for designing ergonomic farm work shoes.

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.

The engineering characteristics and the reinforcement effect of the elephant foot method were discussed with parametric study. The elephant foot method is adopted to support the loads transferred from tunnel crown and improve bearing capacity of elephant foot in poor ground condition. The evaluation of reinforcement effect, which has the mechanical relationship between ground condition, footing size and reinforcement system, was carried out through the previous research and numerical analysis. In addition, the simple design chart was proposed to estimate the applicability of the elephant foot reinforcement method. It will be practical for the engineer to determine the optimum reinforcement method for safe tunnelling in soft ground condition.

Background: Flexible flat foot is that the medial longitudinal arch collapses in weight bearing and returns normal arch when weight is removed and the weight bearing shifts toward medial part of the foot, which can cause pathological problems in the alignment of the lower extremities and the entire body. Objective: To compare the foot pressure for adults with flexible flat foot. Design: Quasi-Experimental Study Methods: 24 participants with flexible flat foot were recruited and were randomly divided into Visual feedback Short Foot Exercise (VSFE) group and Short Foot Exercise (SFE) group. To compare changes of foot pressure about pre and post intervention, the contact pressure measurement was conducted. Results: In the VSFE, significant differences were observed for the foot pressure of the 1^st toe, 1^st, 3^rd and 4-5^th metatarsal, midfoot, medial and lateral heel (p<.05). The foot pressure of the 3^rd and 4-5^th metatarsal, midfoot showed significant differences in the SFE (p<.05). The contact pressure of the 1^st toe, 3^rd metatarsal showed significant differences between the groups. Conclusions: Visual feedback short foot exercise can be useful for moving the pressure from medial to lateral part, and can prevent possible pathological problems.

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.

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.

In recent years, the number of foot disease patients due to bad walking habits and living environment is increasing. We examine how patients with mild foot disease according to shoe design characteristics affect satisfaction and purchase intention when purchasing orthopedic shoes. The design characteristics of shoes consisted of functionality, convenience, and aesthetics. It was found that aesthetics had an effect on purchasing orthopedic shoes. Even if the factors of functionality and convenience have little effect, if the aesthetic is high, purchase intention and satisfaction are affected. Various elements are required for design according to the frequency of participation in social activities for each mild foot disease and the purpose of wearing it. It is expected that the development of useful orthopedic shoe designs that patients with mild foot disease can wear in their daily life will lead to practical application and satisfaction by further supplementing the characteristic factors of orthopedic shoe design identified through the research results.

Purpose: This study was done to evaluate the effects of foot reflexology on blood pressure, serum lipids, fatigue and self-efficacy in patients with hypertension. Methods: The research was done between June 23 and July 31, 2003 and the design was an experimental treatment design. The thirty-four participants were assigned to either an experimental group (18) or a control group (16), Foot reflexology was administered twice a week for 6 weeks to participants in the experimental group. Results: There was a significant decrease in systolic blood pressure and diastolic pressure in the experimental group compared to the control group. After the foot reflexology, total cholesterol and triglyceride levels for the experimental group did not decrease significantly compared to the control group. High density lipoprotein find low density lipoprotein levels also did not decrease significantly after foot reflexology Fatigue in the experimental group decreased significantly after foot reflexology. Self-efficacy in the experimental group did not decrease significantly after foot reflexology. Conclusion: The results show that foot reflexology is an effective nursing: intervention to decrease systolic blood pressure, diastolic blood pressure and to treat fatigue but not serum lipids. Therefore, blood cholesterol should be further evaluated with a larger group of participants and for a longer period. Further research is necessary to evaluate and to compare effects of self-foot reflexology and foot reflexology.
