The major kinematical variables acting upon shooting motion can be described as follows; foot touch point coordination , each shooting movement time, ball velocity angular change of lower limbs segment. The analysis of the above variables presents the following findings: Instep and infront of the ball and the touch foot from the left and right position was significantly different from these of inside. There was stability from the inside position. In terms of the time required for each shooting motion, there was an average of 38.6±18.2 m/sec in TSP stage and 66.8±9.7 m/sec in SSP stage. Maximal velocity showed the mean 24.60±1.45 m/sec. No difference was shown among different types of shooting. Shank segment angle descended toward the minus angle from X direction. However, after knee joint maximal flexion the angle became bigger and before and after the impact, it changed into the plus angle. There was no marked difference between instep and infront at the left foot touch time. At the foot touch time in shank segment angular velocity, instep and infront indicated-227.54±217.36 deg/sec showing the minus rotation and inside showed 46.05±261.59 deg/sec. There shooting in swing leg knee maximal flexion displayed the plus angular velocity and the angular velocity of inside shooting increased significantly compared with other two shooting.

윤재만 한국운동역학회 2000 한국운동역학회지 Vol.9 No.2

The major biomechanical variables acting upon kick motion can be described as follows; reaction force and impulse force, joint force moment. The analysis of the above variables presents the following findings. 1. The maximal value to vertical reaction force was 1431.4±310.9N on the average. The value of instep and infront kick was much larger than that of inside kicks. The force to prevent body movement and to accelerate swing leg rotation accounts for this difference. The average impulse force of the vertical direction was 5720.4±1964N · S indicating the instep kick was mort significant than the other two kicks. This means that inside kick shows a small numerical value in vertical direction velocity change. 2. Dorsi flexion/plantar flexion moment in the right ankle joint from a kicking position in comparison with knee and hip joint, flexion/extension moment showed a form similar to a slow parable shape. The maximal flexion moment emerged when the right foot was off and the impact was in the range of 40-60%

This paper aims to find ways of tackling stagnant factors in the foreign language education on the college level. Here the foreign language learning is geared to a working command of the foreign language with the view to having access of the advanced foreign technology. And the working command of the foreign language requires not only language skills but a thorough understanding of the cultural background of the language. However, to incorporate all of the cultural aspects into a textbook is a really exhaustive work and is too bulky for a short course to handle all the aspect of the culture. A partial mastery is to be recommended with a condition that a spiral approach must be used to cover pertinant aspects and, in some cases, peripheral aspects which play important key roles. As to the methodology of the lesson, this paper is not to side any one method and it rather intends to persuade using any method out of the whole spectrum of the methodolgy which comes handiest in the specific occasion. This paper also believes that "All methods are best!" However, the present situation in Korea seems to draw a conclusion on the foreign language education as a reading skill is most desirable. Reading materials must indeed be ones which cover all the aspects of the foreign culture in question and must also be such day-by-day reading materials as newspapers, magezines, and everyday documents. This paper eventually tries to make suggestions that; (1) the foreign language education should be extended over the full-four-year period of time with five to ten hours of the foreign language class a week; (2) only the elites should be admitted to the foreign language class who are to be screened by tests of aptitude, intelligence, motivation, and attitude; (3) the size of a class should not exceed the limit of ten students; (4) the text book should not be limited to a book, though it encloses every items of a culture, but be flexible to permit other every day reading materials come into the class; (5) language laboratory should be exploited; (6) a bilingual education is strongly recommended. This paper also gives way to textbook developers and teachers in the classrooms as to the efforts and merits of materializing and realizing the ideas enumerated here.

Several ways of curing are being tried to improve material's properties and reduce marginal gap. However, all are considering about the pattern of light intensity. It was noted from the preliminary study the change of light wavelength from filter chaning may give an impact on material's property and microleakage. The object of this study was to verify the effect of filters with various wavelength width on the microhardness and microleakage of composite resin; hybrid type of DenFil and submicron hybrid type of Esthet X. Composite resins were cured using 3 kinds of filter; narrow-banded(465-475 nm), mid-banded(430-470 nm), wide-banded(400-500 nm). After the estimation of microhardness, degree of dye penetration and the maximum gap from SEM evaluation were done between 4 groups that showed no difference in microhardness value of the lower surface. The results were as follows: 1. Adequate microhardness could not be gained with a narrow-banded filter irrespective of curing time. At the upper surface. DenFil should be polymerized with middle or wide-banded filter for 20 seconds at least, while Esthet X be cured with middle or wide-banded filter for 30 seconds at least to get similar hardness value to control group. 2. There was little dye penetration in enamel margin, but all dentin margins showed much more dye penetration irrespective of curing conditions. Although there was not statistical difference, groups cured with mid-banded filter for 40 seconds and with wide-width filter for 20 seconds showed relatively less dye penetration. 3. It was revealed from the SEM examination that group cured with wide-banded filter had the smallest gap without statistical significance. Spearman's rho test showed that the correlation between the results of dye penetration and SEM examination was very low. From these results, it could be concluded that curing with wide-width filter would be better than the other techniques. even though the curing technique using mid-width filter seems to have its own unique advantage.
