Purpose: This study aims to analyze the management environment Provincial and Municipal Professional Soccer Teams based on financial statements at a time when strengthening the financial soundness of domestic professional soccer teams is emphasized. Research design, data, and methodology: This study was sampled using convenience sampling and a total of 607 questionnaires were used. In this study, questionnaires were used as a survey tool, consisting of eight questions in a total of four areas, measuring demographic characteristics, shoe design, shoe functionality, shoe price, and promotion. Results: First, the importance of outdoor brand shoe selection attributes was high in cost-effectiveness, discount, and promotional models, while the satisfaction level was high in shoe size, content, and Model. Second, IPA analysis revealed shoe sizes, promotional models, and discount factors as maintenance and management continuation areas. Content factors have emerged as a competency-focused area. A sense of cushioning and wearing has emerged as an area of further improvement. As a status quo area, shoe laces and cost-effectiveness factors appeared. Conclusions: First, consumers considered the cost-effectiveness of choosing shoes, followed by discounts, and efforts are needed to diversify promotional content to maximize promotion for shoe sales. 3. Domestic outdoor brands are not yet satisfied with consumers.

This survey was carried out to clarify the consumers' behavior related the purchase and use of women's dress shoes. The subjects participated in this study were 386 Korean women. Their age were ranged from 18 to 86 years. The results of this study were as following; 1. The most popular women's dress shoe sizes were 235 and 240. 2. 82.6% of subjects had experienced uncomfortable fit when they wore dress shoes. 3. The subjects aged over 30 years preferred low heel shoes. They valued wearing comfort above fashion trend in shoe design consideration. 4. The subjects aged under 30 years gave more emphasis on fashion trend than comfort and fit when they purchase dress shoes. 5. Consumer's experience of unfit with dress shoes was different with age. The younger subjects complained improper bottom sole shape. The older subjects had experience of unfit with outshell design and material. The subjects aged over 60 years thought that their dress shoe design was too narrow at the toe and lack for flexiblity of shoe material.

In tread brake of freight cars, brake force is produced by the friction between the wheel and the brake shoe. Friction coefficients associated with the brake power, weight variation and brake shoe types should be sensitively treated as the design parameters. The conditions of the car, empty and loaded, should also be taken into consideration in brake force design and the control of brake force has some limitations in terms of the brake system design so that the brake friction materials selection should be considered as important measures to solve that difficulties. Friction characteristics of brake friction materials should remain within the range of maximum and minimum value and the friction performance should remain stable regardless of brake time and temperature. This study presented an experimental evaluation method to secure optimum brake performance by keeping safe brake effect and brake distance by the friction coefficient of the brake shoe of the freight cars.

Lasting machines for shoe manufacturing are continuously developed with the aid of automation and Computer Aided Manufacturing (CAM). Although automation and CAM techniques have tremendously reduced the labor in shoe manufacturing field, 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 indispensable. While CAD datarization takes the fundamental role in the shoe design as well as the shoe 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 is proposed and some data for the control part of the shoe lasting machine are extracted and interpolated from the CAD data. 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. Finally, initial setting data for the lasting machine are extracted from the last CAD data and initial setup parts of the lasting machine.

As women wear shoes for a long time due to aesthetic elements and working environment, many women experience discomfort and deformation in their feet due to their shoes and the production of comfortable shoes is becoming an important issue. The purpose of this study is to investigate the factors affecting the grip of shoes by foot type, shoe design, and wearing attitude of shoes. Through this, we suggest solutions for foot discomfort due to wearing shoes and help to prevent foot related diseases. The study results are as follows; first, a wide foot, square-type, and high or low arch (hollow foot or flat foot) among foot shapes influenced the fatigue and pain of feet, and big feet over 250mm-long, wide feet, square-type feet, and high-arch feet (hollow foot) had an influence on distortion and side effects. Second, among the characteristics of wearing shoes influencing foot discomfort, the higher the shoe heels were, the narrower the surface covering the feet was (pumps and mule), and the shoes with high front heels and narrow back heel area, the shoe wearer had a higher possibility of experiencing fatigue and pain and even had not only fatigue and pain but also side effects when she wore pointed shoes. Third, a shoe wearer experiences fatigue and pain if she wears shoes for a shorter period of time, stay stood while wearing shoes for a short time, and wears shoes that are bigger or smaller than the actual shoe size. Fourth, fatigue and pain experiencers and distortion and side effects experiencers all responded that they change into other shoes to deal with foot discomfort and that they directly massage their feet.

발은 두 가지의 기능을 가지고 있는데 첫째는 추진기능이고 다른 하나는 몸을 지탱하고 보호하는 기능이다. 그럼에도 불구하고 발의 중요성을 쉽게 잃어버릴 때가 있다. 발바닥에는 인체의 중요한 부위들이 축소되어 있어 발이 건강하면 몸 전체가 건강하다고 헤서 발은 제2외 심장이라고 한다. 발이 건강하려면 좋은 신발을 신어야 한다. 신발을 사용용도, 신체적인 조건, 외적조건에 따라 재료, 디자인, 라스트, 패턴, 젯법 등이 다양하다. 좋은 신발은 적합성, 신축성, 그리고 순응성이 있어야 한다. 건강한 신발을 만들기 위해서는 인간공학적이고 과학적인 근거를 가지고 설계하여 제조하여야 한다. 특히 최근에는 일의 능률을 높이기 위해 다 기능성 신발의 개발에 많은 관심을 가지고 있어 본 연구에서는 이를 위해 신발의 기능성에 대한 이론과 실험을 근거로 하여 건강한 구두를 개발코자 한다.

3D finite element analyses of movable bearing shoe and hinged bearing shoe are performed. The finite element models are built using MSC/PATRAN and analyses are carried out using MSC/NASTRAN. Results are again completely processed using MSC/PATRAN. From the results of the analyses, trends of deformation and stress distribution are reviewed and important factors to consider in the design of bearing shoes are discussed. Furthermore optimum crowning amount for the roller of movable bearing shoe was determined according to the results of the analyses.

As the spread of COVID-19 continues, cleanliness and quarantine are emphasized in daily life. If foreign substances enter through the shoe sole when using public facilities, cleanliness may deteriorate and various infections may occur. To prevent this, shoe sole cleaners that filter out foreign substances have been developed. In this study, a design that satisfies structural safety was presented by selecting a new material and updating the design parameter to reduce the weight of the shoe sole cleaner. To evaluate the structural safety, a finite element analysis under selected design loads was performed. Through design improvement and stress analysis, a model that was approximately 85% lighter than the existing model was developed.

Along the various gap distance between shoe and swash plate and pocket diameter, lifting force of piston shoe during the compressing stage was calculated. The flow in piston, orifice, shoe, and back space was considered to be 2-dimension axisymmetric and analysed by Fluent, a commercial CFD Software. The wall boundary condition was given as nonslip and adiabatic, while the change in fluid viscosity was considered as linear along temperature. Calculated lifting force and oil leakage of shoe was used in the design of a pump to confirm the shape of the shoe.
