김수연 ( Su Yhen Kim ),하대현 ( Dae Hyun Ha ) 한국독서학회 2006 독서연구 Vol.0 No.16

초등학교 아동을 대상으로 연구한 보고들을 살펴보면 이야기 텍스트 이해를 설명적 텍스트 이해보다 더 쉬워한다. 이런 차이는 주로 배경지식에 의한 것으로 해석되나 텍스트 이해는 개인의 인지 능력의 영향을 받으며, 인지적 능력의 부족이 이해 능력에 어려움을 가져온다. 본 연구에서는 텍스트의 종류에 따라 어떤 인지적 요인들이 관여하는지를 새로운 지능이론의 관점으로 알아보고자 한다. 본 연구에서 사용된 지능 검사는 현대의 지능이론으로 새로이 제안되는CHC(Cattell-Horn-Carroll) 지능 이론에 따르며 본 연구에서 사용된CHC 지능검사의 신뢰도는 .60-.79이며, 타당도 검증을 위한 탐색적 요인분석과 확인적 요인분석을 실시하여 타당도를 확인하였다. 개인내의 이야기 텍스트를 설명적 텍스트보다 더 이해하기 쉬워한다는 것을 통계적으로 확인하였다. 개인 간 차이로 이야기 텍스트를 더 잘 이해하는 집단과 설명적 텍스트를 더 잘 이해하는 집단 간의 인지적 차이를 살펴보았다. 이야기 텍스트 이해를 잘하는 집단이 Gc(결정지능)와 Ga(청각처리)는 p<.05에서 의미 있는 차이가 있었으며 Gsm(단기기억)은p<.01에서 의미 있게 높은 점수를 보여주었다. 이런 결과는 어려서의 읽기 경험은인지적 요인에 영향을 미치며, 이야기 텍스트를 어려서부터 접하고 경험한 아동의 Gc, Ga, Gsm이 높아질 수 있다는 것을 시사하여 준다. The present study was to explore the relationship between the narrative/expository texts and CHC cognitive ability in 4,5,6 grade elementary school. They were easier to understand the narrative texts than the expository, because of they had not only prior knowledge but also cognitive ability related text comprehension. On the view of recent CHC cognitive ability, this study investigated two types(narrative/ expository) of texts related cognition. The measures of CHC had high reliability and good validity - exploratory, confirmatory factor analysis. The subjects of this study were divided to two groups. The first group was more comprehensible to understand narrative text than expository text. The second group was more comprehensible to understand expository text than narrative text. Between two groups was verified from t-test. The results of this study clearly indicated that the first group was more significant to effect on Gc(comprehension knowledge), Ga(auditory processing) and Gsm (short-term memory) play an important role than the second group.

Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

There are various ways to operate traffic light system by varying the operational speed of the system. One of the solutions is to vary the length of the clock cycle of the system. It is difficult to vary the length of the signal in systems by varying the period of the clock cycle and nor it is a generalized technology in the current traffic systems. The traffic signal systems of the past used is simply a repetitive traffic signal system which traffic period is consistent, not considering the conditions of traffics. The system that will be introduced in this thesis could substantially improve efficiency of traffic flows by varying the length of traffic signal period with sensors which detect the presence of vehicles on both directions and allows the signal continuously on the direction where there are more waiting vehicles, and even skips the signal where there is no vehicle waiting. In this thesis, it introduces the methodology of detecting the spots that is detected by the sensors of the system and outputs green light in due order in accordance with the priority given to the system. In the meanwhile, the ratio of yellow light and green light is designed to be 1 to 8 in the way that maximizes the efficiency of traffic flows.

This research was conducted to examine the effects on the growth in response to position of daughter plant of strawberry (Fragaria×ananassa)‘Seolhyang’ during the pot nursery in rain shelter. Mixture of soil mother material medium and rice hull(1:1, volume/volume) and commercial medium were used for nursery medium. Uniform daughter plants of about 2.5 expanded leaves were placed on the center and the side of pot and were investigated the growth characteristics of daughter plants after 60 days. As a result, daughter plants on the side of pot showed a tendency to increase total fresh weight, number of primary root, root weight, and crown diameter which is important characteristics of plantlet quality. Number of primary root, root weight, and crown diameter of daughter plants on the side of pot compared to those on the center of pot were increased to 3% and 11%, 7% and 41%, and 5%, respectively. As a result of analysis of root zone using the root analysis system, the total root length, root surface area and root volume of daughter plants on the side of pot compared to those on the center of pot were increased significantly. Those differences were greater in the commercial medium compared to the mixture of soil mother material medium and rice hull(1:1, volume/volume). Thus, it is expected to be improved the plantlet quality of daughter plants and increase the production ratio of high-quality plantlet when daughter plants were placed on the side of pot during the pot nursery in rain shelter.

This study was conducted to investigate the effect of plantlet quality and transplanting time of mother plants on the growth of runner and daughter plants of strawberry (Fragaria×ananassa) ‘Seolhyang’ during nursery. Plantlet quality of mother plants is expected to be able to distinguish on the basis of crown diameter because crown diameter was highly correlated with fresh weight(r = 0.85), leaf area(r = 0.81), root weight(r = 0.75) and 1st primary roots(r = 0.73). Mother plants were transplanted based on the crown diameter (7~9 mm, 9~11 mm, 11~13 mm and 13~15 mm) in 15 March, 2012. Also, mother plants were transplanted in 15 March, 30 March, 15 April, 30 April and 15 May to investigate the best transplanting date. As a result, the number of daughter plants in the treatment 9~11 mm and 11~13 mm were 22.7 and 22.4 respectively at the end of July. But the number of daughter plants in the treatment of 7~9 mm and 13~15 mm reduced 26% and 16% respectively compared to the average number of the daughter plants in the treatment between 9 mm and 13 mm. The number of daughter plants in the treatment of 15 March, 15 April and 15 May were 20.2, 18.8 and 13.2 respectively at the end of July. Early time of transplanting was able to obtain the more daughter plants and improve the plantlet quality of daughter plants. Therefore, mother plants having crown diameter between 9 mm and 13 mm recommended to be transplanted until the end of March to obtain sufficient daughter plants and improve plantlet quality of daughter plants for producing strawberry fruits.

This paper presents a study on the cache(memory) partitioning configurations for meeting deadlines of periodic and aperiodic task set. The purpose of this study is not only to increase the cache utilization, but also to decrease the deadline missing ratio of each task. We discuss the optimal cache partitioning problems for real-time task set. Base on the task execution time and utilization, we suggest the cache partitioning algorithm which computes the segment allocation for a given task set, respectively. The schedulability of task set depends upon task properties and the algorithm used to schedule the tasks. Here, we used the rate monotonic scheduling algorithm modified for considering all periodic tasks and aperiodic tasks together. We checked whether tasks assigned on the configurations are possible to meet the their deadlines or not. We obtained the schedulable configurations, and analyzed the utilization bound of the cache optimal partitioning configuration which the task set is schedulable if its utilization is below a certain bound.

이수대 慶南大學校 附設 基礎科學硏究所 1997 硏究論文集 Vol.10 No.-

When a ferroelastic domain of Gd₂(MoO₄)₃single crystal is switched from Sk state to Sp state by external force, the formulae that can calcuate relativistic displacement of the lattice point and distribution of ferroelastic switching force were derived by this study. The formulae that can calculate threshold switching force in any direction were derived from the conservation law of enthalpy and measured value of threshold switching force in specific direction. Theoretical values of threshold switching force were in accord with measured values at (θ=90˚, ø=15˚), (θ=90˚, ø=30˚), (θ=90˚, ø=45˚), (θ=90˚, ø=60˚) and (θ=90˚, ø=75˚).

In this study, we derived the formulae about enthalpy density per unit force when occured ferroelastic switching. The enthalpy contour lines were calculated from the spontaneous strain tensor and these formulae when was switched from a S₁ferroelastic state to a S₂ferroelastic state. The magnitude and the direction of minimum stress were estimated at the distribution charts of enthalpy density per unit force when was switched from a S₁state to a S₂state and we experimented on these phenomena. The direction that occur the switching phenomenon by the least compression force was the [110] direction when was switched from a S₁state to a S₂state and the switching force was between 60 N/㎠ and 70N/㎠ . Measured, the spontaneous strain tensor, e?? of Gd₂(MoO₄)₃single crystal from strain by the switching phenomenon was 1.57×10??.

K(Nb₁-xVx)O₃ 단결정의 교류전기전도 특성

이수대,설정식 慶南大學校 附設 基礎科學硏究所 1995 硏究論文集 Vol.7 No.-

The impedance and ac conductivity of K(Nb₁-xVx)O₃ are measured by the low frequency impedance analyzer. Ac conductivity depends on the temperature and the frequency. As we substitute V5+ ions more, the phase transition points increase, and the Curie temperature move to higher temperatures. Temperature dependence of the conductivity beleow 10.6Hz can be interpreted as a hopping conduction by charged particles, and that over 10.7 Hz which is nearly independent of the temperature and can be explained as a hopping conduction among impurieties.
