The purpose of this study is to analyze and compare accuracy and kinematic characteristics of forehand strokes upon using the left-hand and non the using left hand in tennis. Six unskilled collegiate players who complied primary tennis course participated in this study. Subjects were requested to hit 10 balls with 4 types each: first, it was two directions(down the line, cross), second, it was two velocities(slow ball, fast ball) and then it was type of using left hand. Variables such as accuracy, time, distance, angle and velocity variables were measured by USPTA method and video cameras. The results of this study are as follows: 1) accuracy of hitting balls was not different according to the type of using left hand. While there was an interaction between ball velocity and hitting direction. 2) impact positions of hitting ball were not different according to the type of using left hand. While impact positions were done near by target direction in cross direction then down the line direction. 3) shoulder rotation angle was not different according to the type of using left hand. While shoulder rotation angle was grater in down the line direction than cross direction. 4) the maximum velocity of racket head was faster in using left hand than non using left hand.

This paper is a thesis on the validity of abbreviation registration that middleman is omitted. Especially, I considered on the validity of abbreviation registration, middleman is omitted, since enforcement of an express provision for registration of immovables, 1990. 9. 1, in this paper. The major contents of this paper can be summarized as follows. Ⅰ. Introduction (1) A background of abbreviation registration in which middleman is omitted. (2) The explanation for the point of an argument. Ⅱ. Typical mode of abbreviation registration that middleman is omitted Ⅲ. Theory and judicial precedent of the former time, September 1, 1990. Ⅳ. Theory and judicial precedent of the later time, September 1, 1990. Ⅴ. The contents of the result be inquired by question. Ⅵ. Conclusion I studied on the validity of abbreviation registration in which middleman is omitted, have concern with an express provision for registration of immovables. The writer think so that validity of abbreviation registration that middleman is omitted must be admitted also even though an express provision for registration of immovables being enforced. The detailed reason for that is stated in chapter Ⅵ.

Dieser Dissertation ist die Auslegung des Wesen als Reflexion in Hegels "Wissenschaft der Logik. In Hegels Denken das Wesen ist erstens 'Reflexion. Die Reflexion bestimmt sich diese Reflexionsbestimmungen, d. i. die Identitat, den Unterschied, den Widerspruch. Die Reflexionsbestimmungen haben zwar die Form, sich selbst gleich und daher unbezogen auf Anderes und ohne Entgegensetzung zu sein; aber wie sich aus ihrer naheren Betrachtung ergeben wird-oder wie unmittelbar an ihnen als der Identitat, dem Unterschied, dem Widerspruch erhellt-, sind sie bestimmte gegeneinander. Daher hat as notig, daB diese drei Reflexionsbestimmungen mit dialektischen Erlegung auslegt, d. i. daB warum es in seiner Gleichheit mit sich ungleich und Widersprechend, in seinem Widerspruch mit sich identisch, und an ihm selbst diese Bewegung des Ubergehens einer dieser Bestimmungen in die andere ist.

In this research, we compare and anlyze the two initial basis construction procedures : LPAKO's procedure proposed by Seo et. al. and symbolic crash procedure proposed by Maros et. al.. Based on the analysis, we present a new procedure which complements the previous procedures. The new procedure shows superiority to the previous procedures with respect to the optimality of initial basis. Also, the initial basis constructed by the new procedure reduces the number of simplex iterations.

In this study, we deals with the implementation of an optimal basis identification procedure for interior point methods, Our implementation is based on Meglddo's strongly polynomial algorithm applied to Andersen and Ye's approximate LP construction. Several techniques are explained such as the used of effective indicator for obtaining optimal partition when constructing the approximate LP, the efficient implementation of the problem reduction technique proposed by Andersen, the crashing procedure needed for fast dual phase of Megiddo's algorithm, and the construction of the stable initial basis. By experimental comparison, we show that our implementation is superior to the crossover scheme implementation.
