본 연구에서는 1985년부터 2001년까지 17년간의 황아귀 어획량 및 노력량 자료와 어획물 체장조사 자료를 이용하여 한국 연근해 황아귀 자원에 대한 자원생물학적특정치를 추정하였다. 어획물곡선을 이용하여 추전된 한국 연근해 황아귀의 순간전 사망계수 (Z)는 0.91/년이며, 어구가입연령 (t_(c))은 1.3세였다. 또한, 자연사망계수 (M)는 0.27/년으로, 순간어획사망계수 (F)는 0.64/년으로, 어장가입연렁(t_(r))은 0.3세로 추정되었다. 황아귀 자원을 가입당생산량 모델에 적용시킨 결과, 가능한 최대 가입당생산량이 948g 임에 비하여 현재의 t_(c) = 1.3세, F = 0.64/년에서의 가입당생산량은 559g 정도로 나타났다. 여기서 t_(c)를 현재 상태로 고정시킨 후, 가입당생산량을 높이는 방안을 생각해 보면, 현재의 F 값 0.64/년에서 증가할수록 가입당생산량은 감소하는 경향을 보이고 있지만, 현재의 어획강도 (F)를 고정시키는 경우에는 t_(c)를 현재의 1.3세에서 4세 부근으로 조정하면 최대의 가입당생산량(948g)을 얻을 수있고, 이 t_(c)값은 역시 F_(0.1)방법에서 추정된 적정 어획체장음 연력으로 환산한 결과와 거의 일치하였다. 또한, 가입당생산량 및 가입당산란자원량 모델을 이용하여 생물학적 관리기준점이 되는 F_(0.1)과 F_(35%) 및 F_(40%)을 각각 0.14/년, 0.26/년, 0.22/년으로 설정하였다. 지난 17년간 어획자료를 사용하여 잉여생산모델에 의해 추정된 MSY는 Schaefer와 Fox 모델에 의하여 각각 7.740톤과 7.720톤으로 유사한 결과를 나타냈다. 또한, CPUE/CPUE_(M8Y) 비는 1보다 큰 값을 보여 황아귀의 자원상태는 한국 TAC 산정을 위한 ABC 추정시스템의 4a 단계에 해당되었다. 따라서, MSY 및 자원상태를 고려하여 한국 연근해 황아귀 자원의 2002년도 관리시점의 생물학적허용어획량은 7,730톤이 적정한 것으로 판단되었다. The purpose of this study is to estimate population ecological parameters, including instantaneous coefficients of natural and fishing mortalities, and age at first capture, as well as to carry out stock assessment of yellow goosefish Lophius litulon (Jordan) in Korean wafers. Using the catch curve, the instantaneous coefficient of total mortality (Z) of yellow goosefish was estimated at 0.91/year and the age at first capture. 1.3 years. The instantaneous coefficients of natural and fishing mortalities (M and F) were estimated to be 0.27/year and 0.64/year, respectively. A yield-per-recruit (YPR) analysis showed that the current yield per recruit of about 559 g with F of 0.64/year at t_(c) of 1.3 years. was lower than the possible maximum yield per recruit of 948 g. With to fixed at the current level, the yield per recruit tended to decrease as the current F (0.64/year) value increased. Thus, it is suggested that the maximum yield per recruit can be attained with a fixed F value at the current level by increasing t_(c) from 1.3 rears to 4.0 years. Based on YPR and spawning biomass per recruit (SPR) models, the biolegical reference points, such as F_(0.1), F_(35%), F_(40%), were suggested as 0.14, 0.26, 0.22 per year at current age 1 of recruitment. Employing surplus production model (SPM) with catch per unit effort of the Korean large stow net fishery during the periods of 1985-2001, the estimated MBYs were similar between the Schaefer and Fox models, ranged from 7,74D to 7,720 mt. Finally, we suggested that acceptable biological catch (ABC) of yellow goosefish in 2002 should be 7,730 mt, based on the MSY and the current status of the stock in Korean waters.

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 study is to examine effects of a differentiated-previous notice system of assessment (DPNSA) on the mathematical achievement. For this purpose, the following problems are established. First, how differentiated materials of assessment are made and put to practical use, which are able to applied practically to the teaching of mathematics? Second, is there any difference in mathematical achievement between the experimental group which has carried into a DPNSA, and the control group which has not? This study was designed to use nonequivalent control group pretest- posttest design. Two fourth grade classes were selected from an elementary school in Chinju city for this study, one for an experimental group and the other for a control group. One calss has carried into a DPNSA and the other has not. In order to achieve the first purpose, analysis of a course of study and aim of mathematical subject are searched, and developing principles of materials for assessment and a standard plan of assessment are ready. In order to develop a DPNSA materials and throw them in the class repeatedly, teaching plans are organized and cooperative learning of small group and self-estimate are practiced during the class. The results obtained from the data analysis were as follows. There was a significant difference between the experimental group and the control group in mathematical achievement at the significant level of 0.1. That is, this research shows that there was an effects of a DPNSA on the mathematical achievement. The results are like theses. An experiment which has done a DPNSA showed better mathematical achievement than a control group which has not. The fact tells us that the DPNSA make pupils to enhance the mathematical power. By pro-supplying the affairs of problems to the pupils, this study helped to give the opportunity to solve the given problems easily to them. In the part of teachers, the result of assessment forced them to reconsider their teaching and to improve the method of teaching.

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.

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 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.

獨逸文의 配語法 : Die Klammerbildung im deutschen Satz

河斗膝 釜山大學校 師範大學 1975 교사교육연구 Vol.2 No.1

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.
