The aim of this study is to evaluate tennis shoes's plantar pressure distribution in tennis prayers and to determine the influence of the shoe on various tennis movements. When investigating the biomechanics of movement in tennis, one of the first things to do is to understand the movement patterns of the sport, specifically how these patterns relate to different tennis shoes. Once these patterns are understood, footwear company can design tennis shoes that match the individual needs of tennis players. Plantar pressure measurement is widely employed to study foot function, the mechanical pathogenesis for foot disease and as a diagnostic and outcome measurement tool for many performance. Measurements were taken of plantar pressure distribution across the foot and using F-Scan(Tekscan Inc.) systems respectively. The F-Scan system for dynamic in-shoe foot pressure measurements has enabled us to assess quantitatively the efficacy of different types of footwear in reducing foot pressures. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right, left shoes. For this study 4 university male, high level tennis players were instructed to hit alternated forehand stroke, backhand stroke, forehand volley, backhand volley, smash, service movement in 4 different tennis shoes. 1. When impact in tennis movement, peak pressure distribution of landing foot displayed D>C>B>A, A displayed the best low pressure distribution. A style's tennis shoes will suggest prayer with high impact. If prayer with high impact feeling during pray in tennis wear A style, it will decrease injury, will have performance improvement. 2. When impact in tennis movement, plantar pattern of pressure distribution in landing foot displayed B>A>C>D in stability performance. During tennis, prayer want to stability movement suggest B style tennis shoes when tennis movement impact keep stability of human body. B style tennis shoes give performance improvement 3. When impact in tennis movement, plantar pattern of center of force(C.O.F.)trajectory in landing foot analyzed this : 1) When stroke movement and volley movement in tennis, prayer better to rearfoot movement. 2) when service movement, prayer midfoot strike movement. 3) when smash movement, prayer have forefoot strike movement.

This survey reports on the extensive examination of the qualify of 14 jogging and tennis shoes separately, availavable in the domestic market, Both jogging and tennis shoes were catagorised in two groups, namely the general goods(less expensive ones) and the exclusive goods(expensive models). The detailed classification are shown below; The domestic products meet the general purpose just as that of the foreign products. Due to the adhesion technology, the domestic tennis shoes consist of rubber sole with natural leather upper;In fact, the desirable combination, as foreign products, must be polyurethane/natural leather. The expensive models were heavier than the less expensive ones. The greater weight difference of right and left shoes are shown in the expensive models than that of the less expensive ones. The moisture absorption ratio of the expensive model is far superior in comparison with the less expensive model. The reason is identified by the material supplyed to produce the expensive model consisted of the natural leather and proper parts. The abrasion resistance of the expensive models were excellent that of the less expensive ones, because the rubber soles were showed the properties better than polyurethane sole which was used in the less expensive model.

A long-term bed rest results in an inevitable foot drop. Yet preventive device such as a foot board and high-neck tennis shoes, are not widely used. This study was conducted to compare the effects of a pillow-type foot board with that of the band-type device. The band-type device of a resonable price is designed for an effective prevention of foot drop, and the convenience for it use. Among the non-equivalent control group design, foot drop preventive effects, usefulness of the device, as well as its cost effectiveness were examined. The study was carried out for four months from December 1999, and its subject had been patients and nurses of two intensive care units at K medical center in Seoul. According to the study purpose, the data collected were analyzed by $x^2-test$ and t-test. The results are as follow : 1. The ROM of ankle joint is promoted in the experimental group with a band-type device comparing the control group with a pillow type one. Dorsiflexion is particularly increased in the experimental group as compared with the control group, while planterflexion hardly shows any change. 2. The usefulness score of the experimental group nurses using the band-type device (23.97) is higher than that of the control group nurses (18.88). 3. In an aspect of the unit production cost, band-type devices are low-priced compare with pillow-type or other foot board (wooden) or high-neck tennis shoes. In summary, the newly developed band-type device is both useful and preventive for a foot drop. It is also desirable regarding to the production cost and the cost effectiveness. This fact proves that the new anti-foot drop device could be practical both for clinical care and home care. Yet the results were obtained by some subjects, it should be used after a further examination. More effective nursing intervention could be observed throughout general studies, including proper positioning and foot and ankle exercises which are the important variables of the foot drop prevention.

The objective of this research is to examine psychological desires of college students who attempt to express themselves by wearing so called 'couple look' attire, which is a dressing habit that represents responses to various psychologies and the society. Moreover, the message that is trying to be conveyed to others by dressing as such and the question of whether that message is being conveyed, are subject to analysis by applying linguistic classification theory pertaining to this specific term. After a pre-examination based on a through interview conducted with 70 male and female college student, the main examination was based on question and answering methods on 450 male and female college students for data collection. The results were compared, reviewed and analyzed by applying Geoffrey Leech's meaning segmentation theory on linguistics, and was aimed at defining through research how meaning segmentation represented through languages can be applied in expressing one's self through clothing. The research results are as follows. 1. The psychological desires of wearing couple look attire are to express that they like and love each other, are dating, and to showcase their intimacy. 2. Clothing attire that are appropriate to express the couple look are T-shirts, jeans, pants, sweaters, mufflers, and accessories such as tennis shoes, hats, shoes, bags, rings, watches, ear-rings, etc. 3. Amongst people who have tried the couple look and those who have not, those who have said that they were willing to dress in couple look are mostly experienced in dressing so.

Purpose : The purpose of this study was to identify whether static and dynamic balance in young men were influenced by the different height of insoles in their shoes. Methods : Eighteen healthy young men (mean $20.61{\pm}1.38years$) were recruited for this study. The subjects' static and dynamic balance were assessed while wearing three different height' insoles (0cm, 2cm, 3cm) in their tennis shoes. Anterioposterior (AP) and mediolateral (ML) sway velocity was measured for 20 seconds using a force plate (Good balance system, Finland) under four conditions including normal standing with eyes open and with eyes closed, and tandem standing with eyes open and with eyes closed. The Functional Reach Test (FRT) and Timed Up & Go (TUG) were also performed for each subject under each condition. Results : 1) ML and AP sway velocities in young men were significantly different according to the height of the insole in normal standing with eyes open and eyes closed. 2) ML and AP sway velocities in young men were not different according to the height of the insole in tandem standing with eyes open. 3) ML sway velocities in young men were significantly different according to the height of the insole in tandem standing with eyes closed, whereas AP sway velocities did not differ by height of the insole in tandem standing with eyes closed. 4) FRT scores in young men were significantly different according to the height of the insole. 5) TUG scores in young men were not significantly different according to the height of the insole. Conclusions : This study's results indicate that the static and dynamic balance in young men can be influenced by shoe insole height.
