The purpose of this study is to develop Korean shoe-last based on the conformability of shoe. For this work, the important dimensions for the conformability of shoe were investigated and the systematic methods for evaluating the comfortable shoe were developed. Different two types of shoe-last for men and women were used in the experiment, respectively. 8000 feet dimensions of Korean adults were analyzed for developing standard shoe-last in this study. A total of 10 subjects (ranged from 21 to 25 years old) participated voluntarily. They evaluated each shoes made by developed shoe-last. A rating scale and description was used to express the degree of conformability. Also, 26 feet dimensions were measured using martin-typed gauge and footprint. The relationship between foot dimension and conformability of shoe was analyzed. As a result, Korean standard shoe-last was suggested based on the based on the conformability of shoe. The evaluating methods will be expected to help designer find more important design parameters. We will also expect that the standard shoe-last guarantee the optimal gait and minimal workload, especially in aspect of conformability.

The purpose of this paper is to investigate the customer's requirements for shoe products using the survey method, to analyze customers' needs, and to supply information to make the shoe that they want. For this work, we made 38 survey items for the degree of shoe satisfaction, for foot care and shoe control, for shoe characteristics, and for shoe purchase in future. For the purchase of shoe products in future, customers in their twenties gave the highest score for shoe design among price, design, size, fashion, fitness, color, brand, so forth. However, respondents in their forties selected the degree of fitness instead of shoe design. In the question for the buying price of shoe products in future, all customers wanted shoe products between 30,000 won md 50,000 won.

This paper is concerned with the mutual relationship among interpressure, last. foot within a new shoe and foot within a fifty-hour-used shoe at the standing posture at three different heel-heights 1. The interrelationship between the heel-heights and interpressure is very significant at the level of $0.1\%$. The heel-heights cause high interpressure at different parts of foot; heel point and big toe point in a 3 cm-heel shoe, big toe point and heel outside joint point in a 5 cm-heel shoe, and little toe point, heel-outside joint point, and arch point in a 7 cm-heel shoe. 2. Foot girth and foot width measurements either within a new shoe or within a fifty-hour-used shoe significant at the level of $5\%,\;1\%,\;0.1\%$ and show discrepancies at three different heel heights; the part between instep and ball joint in a 3 cm-heel shoe, toe part in a 5 cm-heel shoe, heel-inside joint. heel-outside joint and toe part in a 7 cm-heel shoe are highly influenced by heel heights. The higher the shoe-hee15 are, the more heavily the fore part of foot is pressured in lateral direction because shoe is made to have high instep from a fashion viewpoint. Higher shoe heels prevent weight pressure from being concentrated on heel. If shoe heels are toe high, people in such shoes feel easily tired. It is very worthy of note in selecting shoes to consider not only the shoe fashion but also fore shoe type, heel height, and shoe material with proper elasticity.

The purpose of the study is to examine the effect of the spring shoe through the comparison of spring shoe to general shoe. For this, 12 healthy females in the age from 20 to 30 years participated in the E.M.G. experiment with testing kinematic variables. Results indicated that there was significant differences in angle of ankel between the general and spring shoe. Specifically, the spring shoe showed a bigger angle of take on and a smaller angle of take off in walking than the general shoe. This mesns that the spring shoe does not have a significant effect to produce efficient and smooth walking. In addition, the spring shoes revealed a bigger rear-foot angle than the general shoe in the evaluation of rear-foot control function. This means that the rear-foot control function of the spring shoe is low compared to trhe general shoe. Meanwhile, there is no significant differences in angle of knee and angle of Achilles tendon between both shoes. In an analysis of E.M.G., the significant differences were found in gastrocnemius muscle, anterior tibial musculi, musculi rectus femoris, biceps muscle of thigh between both the general and spring shoe groups by the section. In the case of gastrocnemius muscle, the spring shoe showed a low muscle production of anterior tibial musculi than the general shoe. This is a result from structural nature of the sole of a foot of the spring shoe. The spring shoe performs a rolling movement through slightly large pronation toward front-foot from rear-foot in supprt time before taking-off of toe and the power for this movement is mainly produced from musculi rectus femoris.

고속철도 KTX 차량의 답면제동은 전기제동이 작용하지 않는 저속에서 열차를 정거장의 정위치에 정차시킬 때 주로 사용되는데 그 동안 균열발생, 제륜자 키 탈락 등 잦은 고장이 발생하였다. 본 연구에서는 이러한 고장의 원인을 규명하고 각 고장에 대해 해결책을 제시하고 시험평가를 통하여 개선효과를 검증하였다. 제륜자 키와 캠의 강도향상과 제륜자 마찰재 지지판의 강도향상은 제륜자 마찰재의 균열발생을 약간 줄이는 효과는 있었다. 지지판의 강도향상, 구조개선과 함께 제륜자의 재질을 변경하였을 때 마찰재에는 균열이 거의 발생되지 않았다.

We analyzed the pressure, impulse on 24 sensors location under the foot using the Parolee system. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with those of sport shoe, greater pressure and impulse were shown on the 1 st phalange and the 1 st metatarsal head and greater impulse on the medial tarsal bone in high-heel shoes. Greater pressure and impulse were shown on medial metatarsal bone and the lateral tarsal bone in platform shoe. Greater impulse was shown on the medial tarsal bone in inline-skate. Heelys shoe showed smaller impulse on the central area of foot. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.

Lasting machines for shoe manufacturing are continuously developed with the aid of automation and CAM(Computer Aided Manufacturing). Although automation and CAM techniques have tremendously reduced the labor in shoe manufacturing, there still remain some parts manufactured by experts. In order to enhance the capability and efficiency of machines for labor-free shoe manufacturing, CAD data of a shoe last is essential. While CAD datarization takes the fundamental role in the shoe design and manufacturing, there has been little research for the CAD datarization of a shoe last. In this paper, a new procedure for CAD datarization of a shoe last using finite element patches and a tension sl)line method is proposed for application to shoe manufacturing machines. The outer line of a shoe-last sole is interpolated by a tension spline method and bonding lines are extracted from the shoe CAD data. Data set for a control algorithm of the tasting machine can be produced from the CAD data.

Track shoes improve the off-road driving ability of tanks. The strength of the track shoe body directly affects the driving ability of tanks, self-propelled artillery, and armored vehicles. In this study, the design technique for track shoe body was investigated. To select the optimal design of track shoe body, three track shoe body models were suggested and compared. Tensile strength was calculated using computer-aided engineering (CAE) analysis. Compressive tests were conducted using the original tank sprocket because sprocket compression is critical to the lifespan of the track shoe body. As a result, one track shoe body design was selected and the process of track shoe body design was described.
