A variety of difficulties in the learning of algebra are caused by overlooking obstacles emerging in the process of shifting from arithmetic to algebra. However, the studies focused on the transition from arithmetic to algebra are not so many, although children's earlier experiences of arithmetic play an important role in their studying mathematics in high school. There is a fundamental relation between the difficulties that students feel in the learning of algebra and the experiences that they acquire in the learning of arithmetic. There are some arithmetic knowledges that give rise to obstacles in the learning of algebra, although the greater part of them are useful. From this point of view, in this paper, we set up seven types of obstacles that emerge in the transition from arithmetic to algebra, and present teaching methods about these types of obstacles.

Multi-Domain 방법을 이용한 TN-LCD의 광시야각 구현

김영식,김일두 단국대학교 1999 論文集 Vol.34 No.-

Multi-domain method has been used for broadening the viewing angle of TN-LCD which is generally showing an unsymmetry in the up and down side and a narrow viewing angle in the up side. We measured the orientational order and the T-V curve to find out the suitable rubbing strength of the multi-domain cell. The characteristics of the cell was estimated by measuring the viewing angle and the gray scale. The four-domain cell has a symmetrical wide viewing angle in every side and the gray inversion is not occurred in any side. The multi-domain cell is found to be useful in application of the gray scale.

The purpose of this paper is to study the pronunciation in German, compareing with the ^English prouunciation. In German pronunciation there are many rules and phonetic symboles, but they are very systimatical. In German words, there are no silent letters, Theretore euery letler must be pronounced, when a nowel letter is betore h, they say that this h is not pronouned and it must be silent, but this saying is not good and not right. This is aopsed to the fact. Contrary to it, we pronounce the vowel. It means a long 'form of the wowel letter. In this care the h is not silent and it is a phonetic symvole and a ,=good letter. The main contents of this paper are as follows. I. The vowel letters 1. The kinds of vowels 2. The long and short form in the vowel. 3. The simple vowel 4. The Umlaut (changing the sound) 5. Diphthong JI. The consonent TV. The accent in the word. Y. The sentetnce stress. II. The conclusion

The purpose of this paper is to study the sentense construction in German. In German we have five elements of sentence: subject, predicate verb, object, adverbial, and attribute. Subject and predicate verb are called main elements and object adverbial and attribute are called secondly elements. In English they have also five elements of sentence, but subject, verb and object are called main elements and the other two secondly elements or modifiers. In German we have three kinds of sentense constructions, while in English they have five standard sentense patterns. That is: 1.the normal word-order construction 2.the inverted word-order construction 3.the construction of setting the finite verb in the end of a sentence. In the second part and the other six parts, I have tried to research all kinds of sentence forms, and to explain and systemise all these according to the principle of Frame Construction in German. The main contents of this paper are as follows: 1.The definition of the sentence 2.The elements of German sentence 3.The position of subject 4.The position of predicate verb 1)Subject and finite verb 2)The frame Construction in German 3)The position of predicate noun and adjective 5.The position of object 6.The position of adverbial 7.The inverted word-order construction 8.The construction of setting the finite verb in the end of a sentence.

Rayleigh 광산란 실험방법을 이용하여 액정 Octyloxycynobiphenyl(8OCB)의 네마틱-스메틱 A 상전이 근처의 네마틱상에서 산란된 빛의 세기를 온도의 함수로 측정하였다. 실험 데이타 분석으로부터 bend 탄성상수(K₃)에 비례하는 세로 방향 상관거리 ??가 임계지수 ??=0.64±0.02를 갖고 발산함을 알 수 있었다. 이 결과는 de Gennes의 모델에서 계산된 값인 ??=0.67과 유사함을 알 수 있었다. By utilizing the Rayleigh light scattering technique, we have measured the temperature dependence of scattered light in the nematic-smectic-A phase transition point of Octyloxycynobiphenyl(8OCB). The temperature dependence of bend elastic constant K₃is deduced from analysis of this data, and it is found that the longitudinal correlation length ?? diverges with critical exponent ??=0.64±0.02. This result is similar to de Gennes's prediction ??=0.67.

The purpose of this study was to offer gymnasts data for successfully performing triple back somersault dismount(TBSD) and for designing training programs to progress gymnasts to the advanced dismount skills from the horizontal bar through comparative analysis of selected biomechanical factors of single back somersault dismount(SBSD), double back somersault dismount(DBSD) and TBSD. The subjects employed were a total of 4 male middle and high school gymnasts aged between 15 and 16 years. A motion-picture camera, fliming at a nominal rate of 54 frames/s, was used to record the performance of subjects on each trial. This camera was placed at a distance of 15 m from the inward pole of horizontal bar with its optical axis at right angle to this pole. The results obtained are summarized as follows: The mean release angle was 80.5° for the SBSD, 77.3° for the DBSD and 71.3° for TBSD. There were significant differences between the SBSD and the TBSD(p<0.01), the DBSD and the TBSD(p<0.05) but no significant difference between the SBSD and the DBSD. The angular velocity at release was 4.533 ㎭/s for the SBSD, 5.338 ㎭/s for the DBSD and 6.020 ㎭/s for the TBSD. There was a significant difference among these velocities(p<0.05, p<0.01). The linear velocity at release was 5.458m/s for the SBSD, 5.750m/s for the DBSD and 6.083m/s for the TBSD. In this case, we had a significant difference only between the SBSD and the other two somersaults(p<0.05, p<0.01). The shoulder angle at release was 170.5° for the SBSD, 167.0° for the DBSD and 154.3° for the TBSD. There were significant differences between the SBSD and the TBSD(p<0.05), the DBSD and the TBSD(p<0.05) but no significant difference between the DBSD and the TBSD. The hip and knee angle at release were increased respectively by increasing the number of somersault but showed no significant difference among these angles. The mean flight time from release to landing for each somersault was calculated; it took the subjects 1.315s to perform the SBSD, 1.345s to perform the DBSD and 1.416s to perform the TBSD. There was a significant difference among these somersaults with respect to time(p<0.05, p<0.01). The mean maximum height was 3,633m for the SBSD, 3,720m for the DBSD and 3,780m for the TBSD. There was a significant difference only between the SBSD and the other two somersaults. The mean horizontal distance was decreased respectively by increasing the number of somersault but showed no significant difference among these somersaults with respect to distance. The smallest hip angle during flight in the SBSD was 115.3° at 0.317s after the subject left the bar, for the DBSD it was 48.2° at 0.621s while that of the TBSD was 32.3° at 1,102s after release. The relationship between the time the smallest hip angle observed and the total flight time was determined; it took 24.1% of the total flight time of the SBSD to reach the smallest hip angle. In the DBSD, it took 46.2% of the total flight time to reach for the smallest hip angle and in the TBSD 77.8% of the total flight time to reach the smallest hip angle. From the above results, the gymnast would need to (1) increase angular velocity before release by manipulating of body shape, (2) change the release angle and (3) stay tuck position longer by shortening as quickly as possible the angle of each body joint to perform successfully the TBSD. Also to be able to perform quadruple back somersault dismount, a gymnast would need flight time of a minimum 1,782s.

The DOA(direction of arrival) of DS-CDMA signals for mobile communication environment was estimated using non-parametric algorithm and MUSIC(multiple signal classification) algorithm. The non-parametric algorithm with regularizing sparsity constraints achieved super-resolution and noise suppression. effectively. This algorithm offered the increased resolution and significantly reduced sidelobes compared with MUSIC algorithm. The numerical analysis showed that it can accurately find DOA and improve the detection probability of the multiple signals.
