The document delivery service is an advanced service to satisfy information need of end-user by the cooperative utilization of information. At present there are various interpretation on library exemption of the document delivery service by interlibrary loan. The purpose of the study is to suggest a legal plan in order to solve the problems of library exemption dealing with the document delivery service by Fax and Ariel system. The study examined the international trends on library exemption related to the document delivery service in foreign copyright laws, analyzed the library exemption related to the document delivery service in the present Korean copyright law, and pointed out the problems of the present library exemption. As the result of this analysis, the study suggested a revised plan of the present Korean copyright law in order to provide regulation of library exemption dealing with the document delivery service by interlibrary loan. Thus the revised plan can be used as a basic data for providing the regulation for the future of library exemption in Korea.

The purpose of this study was to investigate relation between fastball motion and longtoss motion, and the kinematical analysis using APAS(Ariel Performance Analysis System). Eight people(age: $21.2{\pm}3.6years$, height: $177.1{\pm}3.1cm$, weight $68.6{\pm}2.5kg$) participated in the experiment. Followings are the conclusion. In displacement of fore-aft on COG(Center of Gravity), fastball motion moved more forward than longtoss motion. In displacement of vertical on COG(Center of Gravity), fastball motion was lower than longtoss motion In velocity of right hand, greater release velocity was measured for fastball motion than for longtoss motion. In displacement of elbow and shoulder joint, more extended displacement was exhibited in fastball motion than longtoss motion. In displacement of trunk tilt, fastball motion showed foreward tilt, longtoss motion showed backward tilt. In stride, fastball showed longer than longtoss.

The purpose of this study was to analyze the impact accuracy and kinematic parameters of skill level and eye-tracking type during putting strokes. For comparison, five elite golfers and five novice golfers participated in this study. Three-dimensional kinematic data were collected for each subject while 10 putting trials were performed for each skill level and eye-tracking type. The APAS system was used to compute the impact accuracy and kinematic parameters of putter heads. The putting stroke was divided into three phases: back swing, downswing, and follow-through. The findings indicated that significant differences were found in skill level as it affected the rate of success. For impact accuracy and the displacement of putter heads, a significant difference was found for the skill level, particularly in backs-wing and follow-through. In addition, the displacement of the putter head had a greater influence on stroke accuracy than on velocity.
