Some authors suggest that certain types of surfaces are the origin of such injuries. A few years after the first medical concerns about surfaces were voiced, publications of biomechanical measurements apperared, describing accleration, force, and impact measurement on different types of surfaces. In many sport activities, surfaces can be under very high dynamic load. This was the reason for the development of various methods for impact simulation, like the development of various methods for impact simulation, like the artificial athlete. Furthermore, it is important to collect information about the hardness of new and already existing surfaces in sport arenas. The idea on which this measuring system is based Is as follows: The stiffness of the material can be computed from the kinematics measurd at touch down of a rigid body onto a material sample. The results show the following The result for the artifical surfaces(Synpave ace) is surprising. It is known that these surfaces are much harder than synpave rebound classic, synpave spring. This finding suggests that it may be possible that the subjective impression is used as one criterion in the selection of landing(or style) strategies. The number of subjects in this experiment is too small to make statistically significant conclusions. It is shown analytically that when an object a deformable surface, the acceleration it experiences is inversely propotional to its mass. In future, it need to stress that the interaction between shoe and surface is important, and this aspect has now become well accepted. Considering biomechanical aspect in player's injury, it request Korean Standards for synthetic playing surfaces in sport like ASTM(America Society for Testing & Materials) standards of America, DIN 18035 standards of Germany, BSI standards of U.K.

In recent years, numerical simulation of human body motion has received an increasingly wider range of application. Computer simulations have greatly contributed to the understanding of kinematics and dynamics of human motion. Such simulations are being used in ergonomics to better understand and thus improve the interaction of persons with machines and with workplace configurations. In sports, the simulations are being used to optimize performance, to develop equipment for injury prevention, and to speed and enhance recovery from injury. Then in this study simulated one arm curl motion for understanding force and moment in arm's each joint, and this segment modeling was used 2-dimension, 3-link system. From simulation of mathematica 3.0 we found kinematic and kinetic factors with imaginatively lift of dumbbell and simulated random value of the last curl angle, weight of dumbbell, cycle of motion and so on. The conclusions of this study is as follows ; 1. As this study link system, weight of dumbbell influence not a stance and motion but magnitude of force and moment. 2. The force showed even as smooth curve in all cycle. Moment showed biggist between 0.5sec and 1.5sec. The magnitude order is shoulder, elbow and wrist joint. 3. Motion of system in this study is very similar human arm's motion considering that law of inertia and helped effectively delegation of force. 4. Mathematica is useful language as simulation program. Forward it needs study about modeling and simulation on muscle factors, also human body simulation.

메타의사소통은 의사소통의 '수호천사'인가?

조국현 한국독어독문학회 2003 獨逸文學 Vol.87 No.-

Im vorliegenden Artikel wird ein fu¨r die Kommunikationsforschung a¨uBerst relevantes Thema behandelt, i.e. die Metakommunikation. Die Metakommunikation kann im Rahmen eines Dialogs oder Texts dem Erfolg der kommunikativen Handlung dienen, indem sie vor allem auf Probleme des Verstehens und Akzeptierens von A¨uBerungen verweist. Die Kommunikationsteilnehmer reflektieren u¨ber die laufende Kommunikation und bringen dabei gegebenenfalls ihre Reflexionen zum Ausdruck. Metakommunikative A¨uBerungen sind also Resultate von derartigen Akten der Bewusstmachung. Metakommunikation ist zwar das Moment, das die menschliche Sprache von z.B. tierischen Kommunikationssystemen oder anderen Informationssystemen abhebt, aber im Alltagsleben ist ihr Gebrauch oft belastend. Denn die Direktheit oder das Deutlich-Machen der Metakommunikation kann in bestimmten Situationen beim Kommunikationspartner auch auf emotionale Barrieren treffen. Daher ist Metakommunikation je nach Dialog- bzw. Texttyp unterschiedlich institutionalisiert.

언어행위의 이해

조국현 한국외국어대학교 외국어 종합연구센터 언어연구소 1999 언어와 언어학 Vol.24 No.-

This paper is an attempt to describe an action-character of language that is usually called "speech act". In the 60s, J. Austin and J. Searle began the study of this problem in England. Their approach is called the theory of speech acts. Other linguists in Ost-Germany also have studied the communicative functions of language by analyzing the ordinary use of words. This linguistic approach is called functional-communicative language description(funktional-kommunikative Sprachbeschreibung). This paper will discuss the similarities and differences between these two theories. The theory of speech acts studies the phenomenon of language use analytically through what we call the 'modular' method. J. Searle notes which linguistic elements of sentences are to be distinguished in the performance of a speech act. In the utterance of the sentence, the speaker expresses a propositive and an illocutionary force. For example, in the deep structure of the utterance "Does Sam smoke habitually?" we can identify two elements that correspond to the indicator of illocutionary force (F) separately from those that correspond to the indicator of propositional content (p). F: request, p: event that Sam smokes habitually. However, functional-communicative description of the language approaches the study of these problems in a different way that is called 'holistic'. According to this concept, we communicate strategically by planning the overall use of language, usually in three stages - orientation, planning, and formation. It is suggested that the communicative functions of words do not exactly correspond to their syntactic structure, and the goal of linguistic analysis of language use is to discover and collect appropriate expressions that can contribute to the comprehension of the speaker's intention.

기능적 관점에 따른 독일어 문법 교육

조국현 한국외국어대학교 외국어교육연구소 2000 외국어교육연구 Vol.- No.14

요약Der kommunikationsorientierte Sparachulnterricht bemüht sich darum, den Blick auf das Lernziel der sprachlichen Kommunikationsfähigkeit zu lenken. Dabei bergißt man oft, daß der Grammatikunterricht eine Grundlage dafür ist. Eine Grammatik im traditionalen Sienne soll Auskunft geben, was richtig und was falsch ist. Um das kommunikationsorientierte Lernziel zu erreichen, soll die Hrammatik auch dem Lerner helfen können, äußerunger affressatengerecht im sozialen Interaktionskontext zu verwenden. In diesem Artikel betrachte ich die Wortarten der deutschen Sprache unter funktionalem Gesichtspunkt. D. h., die deutschen Wortarten beschreibe ich hauptsächlich auf Grund der unterschiedlichen Funktionen des Wortes zum Satzbau. Ein Ausgangspunkt dafür ist, daß eine Wechselbeziehung zwischen Form und Funktion im grammatischen und lixikalischen Bereich besteht. Substantive, Adjektive und Verben, die deklinierbar sind, gelten als Grundwörter, die im Grunde eine eigene begruffliche Entktät haben:Lebewesen, Dinge, Zustände, Vorgänge, Handlungen, Eigenschaften, Merknale. Um diese begrifflichen Wörter im Satz zu verknüpfen, sind verschiedene Kausformen notwendig. Diese Rolle des Kasus übernehmen z.T. Präpositionen, die mit Konjunktionen Fügewörter genannt werden. Also werden Grundwörter entweder durch den Kausus oder mit z. B. als Proadverben - Grundwörter, aber ihre Hauptfunktion besteht darin, Grundwörtern kennzeichnend zu dienen. Sie werden daher Beiwörter genannt, wie Artikel, die in der regel Substantive begleiten.
