Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end point is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average date reception rate. At that time, we used evaluation parameters such as node's mobility -stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

A longitudinal study was conducted to determine the physical maturity characteristics of athletes engaged in the following extracurricular sports activities over the three-year junior high school period : basketball(N=40), baseball(N=130), volleyball(N=54), soccer(N=86) and a non=athletic group(N=37) which did not participate in sports. Each athlete's maturity was determined from the age of maximum increment in height (MIA) of each individual. Longitudinal stature measurements were recorded annually in April for 12 years period from 6 to 18 years of age. The study yielded the following results : 1. The MIA distributions of all the sporting groups were distinctly larger than that of the non-athietic group, increasing with each chronoiogical age step on the distance curve and annual increase in height curve. The MIA mean value for the soccer group was significantly higher(P<.05) than those of the non-athletic and all the other sporting groups. 2. The soccer group was significantly slighter(p<.05) in stature than all the other sporting groups. 3. Subjects who played baseball throughout high school reached physical maturity earlier than those who only played throughout junior high school. However, those who continued to play soccer throughout high school reached maturity later than those who only played throughout junior high school.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are 1.74±0.33% (warp direction) and 1.35±0.23% (weft direction) and the polyester fabrics are 1.45±0.22% (warp direction) and 1.25±0.23% (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have ±16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about 1∼3 cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HG5 were decreased more than one for original fabrics. 3. "Stiffness", "Anti-drape", "Crispness" and "Scroop" hand values decrease and"Fullness & softness", "Flexibility & softness" hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about 1∼5 cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HG5, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.

This study was carried out to investigate the changes of thermal properties such as warmth retaining and contact warm/cool feeling of a core knitted fabric by repeated washing. Three kinds of knitted fabric such as core, polyester/cotton(P/C), and cotton were repeatedly washed, and then used as specimen. Thermo Labo Ⅱ type was employed to measure the thermal properties of warmth retaining and contact warm/cool feeling. And also, the experimental results were analysed statistically to related the thermal properties and structural properties such as thickness, weight, bulk density, porosity, cover factor, and air permeability. The results are as follows. 1. The warmth retaining and the contact warm/cool feeling were remarkably changed at early washing, and after further washing no changes occured. The change rate of the materials to repeated washing was in the order of cotton>P/C>core knitted fabrics. 2. In case the knitted fabric of the same thickness and of the same weight have been considered, the warmth retaining was in the order of P/C>core cotton knitted fabrics. And also, the contact warm/cool feeling was in reverse order of the warmth retaining. 3. The warmth retaining showed positive correlation with thickness, weight, porosity, and cover factor and negative correlation with bulk density, and air permeability. And also, the contact warm/cool feeling showed an opposite trend to the warmth retaining 4. The warmth retaining and the contact warm/cool feeling were expected by measuring the structural properties such as thickness, weight, bulk density, porosity, cover factor, and air permeability according to the obtained regression equation.
