이정화,이미은 미래유아교육학회 2003 미래유아교육학회지 Vol.10 No.4

DAP(Developmentally Appropriate Practice)는 유아교육실제의 질을 진단ㆍ평가하는 타당한 기준으로 인정받고 있을 뿐 아니라 유아교육과정의 설계나 프로그램 개발에 고려해야 할 준거로 널리 활용되고 있다. 본 연구는 DAP 신법에 근거하여 만들어진 절차화된 유아과학 교수ㆍ학습모형(이정화, 2002)을 유아교육 현장에 적용하여 그 효과를 검증해 보고자 하였다. 이를 위해 연구자들은 두 가지 교수학습방법(DAP 신념에 근거한 유아과학 수업모형과 전통적 수업모형)을 적용한 과학활동 프로그램을 구성, 처치한 후 유아들의 과학적 호기심 및 과학적 과정 기능의 향상 정도를 살펴보았다. 연구결과 DAP 신념에 근거한 절차화된 유아과학 교수ㆍ학습모형에 의한 과학활동 프로그램에 참여한 유아들이 전통적 교수법에 의한 과학활동 프로그램에 참여한 유아들보다 유의하게 높은 향상을 보였음이 확인되었다. The purpose of this study was to examine the effects of a developmently appropriate model of teaching science(DAP model) which is developed by Lee Jeong-Hwa(2002) on children’s curiosity and scientific process skills. Two research questions were made from the review of the literature, as follows ; 1. Are there any differences in science curiosity between children in an experimental and a control group? 2. Are there any differences in science process skills between children in an experimental and a control group? To answer the questions, forty five-year-old children attending a preschool in Busan participated in this study. They were randomly assigned to either an experimental or a control group. Children in the experimental group, took part in eight 40~45 minute sessions of science program based on the DAP model; whereas, their counterparts in the same sessions of a traditional science program. After the sessions of each program, all children were tested on the science processing skill test and the science curiosity test. The children who took the DAP model received higher achievement than their counterparts on curiosity and scientific process skills. From the results, the researchers suggest to apply the DAP model of teaching science for young children in the education field.

Bae, Kee-Hwa,Yoo, Kyoung-Hwa,Lee, Mi-Hyun,Jeong, Jae-Hun,Choi, Yong-Eui,Yoon, Eui-Soo The Korean Society of Plant Biotechnology 2013 식물생명공학회지 Vol.40 No.3

Iris odaesanensis Y. N. Lee. is an important endangered and native plant belonging to the family Iridaceae in Korea. This study describes a method for rapid micropropagation of this species via from leaf, rhizome and root explants derived calli. Leaf, rhizome and root explants were cultured on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) for callus induction. Rhizome explants yielded calli at a frequency of 72% when cultured at 1.0 mg/l 2,4-D. Calli were maintained at 1.0 mg/l 2,4-D. These calli were transferred to MS medium supplemented with 0, 0.5, 1.0, and 2.0 mg/l 2,4-D in combination with 0, 0.5, 1.0, and 3.0 mg/l BA for adventitious shoot induction. The highest number of adventitious shoot (228.9 per petri-dish) were formed at 1.0 mg/l 2,4-D and 1.0 mg/l BA. WPM medium was the best to convert calli into plantlets, where up to 98.2% of calli were regenerated into plantlets. This in vitro propagation protocol should be useful for conservation of this endangered plant.

이기화,정태웅,Lee, Gi Hwa,Jeong, Tae Ung 한국지구물리물리탐사학회 1999 지구물리 Vol.2 No.1

한국자원연구소 지진관측망의 1995-96년 미소지진 자료를 바탕으로 한반도 남동지역의 지각구조에 대하여, Lee (1979), 김상조·김소구(1983), 김성균·정부흥(1985)의 세 지각 모델 중 어느 것이 잔차의 최소자승을 만족하는지 검증하였다. 세 모델 잔차의 뚜렷한 차이가 관찰되지 않았으나, Lee 의 지각 모델이 약간 깊은 진원을 산출하는 경향이 있다. 한반도 지각의 층상구조는 아직 명백하지 않으므로 앞으로 더 많은 자연지진 자료 또는 인공지진 자료를 통해서 규명되어져야 한다. Using the microearthquake data acquired from 1995 to 1996 through the seismic network operated by the Korea Institute of Geology, Mining & Materials (KIGAM), the three P-wave velocity models proposed by Lee (1979), Kim·Kim (1983) and Kim·Jung (1985) concerning the structure of the southeastern part of the Korean peninsula were examined in terms of the least square errors of the P-wave arrival times. The three models do not differ significantly in arrival time residuals except that the Lee's model gives slightly deeper focuses than the others. The layering of the crust of the peninsula is not clear as yet and to be studied by more earthquake and explosion data in the future.

The importance of repeat screening for stomach cancer is well known to decrease deaths from stomach cancer. This study was aimed at assessing practice behaviors and to identify related factors in the aspects of demographic factors, health status and cancer risk recognition, attitude to cancer screening, health behaviors, and inhibiting or facilitating factors to stomach cancer screening in an urban area. Data was collected through self-administered questionnaires from 403 people aged 40 to 69 years from April 23th to May 15th, 2002. Practice behaviors were classified as :"ver"r "ver"and "peat"r "t repeat"rouped based on a recent 5 year screening history. The results were as follows: 1. Among the 403 subjects: "e ever group"as 23.8% and "e repeat group"as 4.0%. The rates of screening were 20.5% for men, 27.8% for those women, and 27.3% for aged 40-49, 24.5% for those aged 50-59, 19.0% for those aged 60-69. The rates of repeat screening were 4.0% for men, 4.1% for women, and 2.9% for those aged 40-49, 6.3% for aged 50-59, 2.5% for those aged 60-69. 2. The main factors associated with adherence to gastric cancer screening were education(post high school vs below : OR=2.44), previous cancer screening(yes vs no : OR=2.61), belief in personal health(no vs yes : OR=2.72), health status(unhealthy vs healthy : OR=3.40), possibility of cancer compared to others(low vs not low : OR=2.56), and regular exercise(yes vs no : OR=2.94). The main factor associated with adherence to gastric cancer repeat screening was other cancer screening (yes vs no : OR=6.33). Consequently, there is a need to change the recognition of the importance and necessity of stomach cancer screening in healthy conditions through health education, and to perform multiple screening tests each visit.

李貞珪,金相會,潘正和 한국문화관광학회 2001 문화관광연구 Vol.3 No.2

As the importance on cultural tourism grows, researches on psychological characteristics influencing tourists' behavior have gradually increased. The purpose of this dissertation is to examine the purchasing behavioral characteristics of cultural tourists being segmented by benefit sought. This research is divided into two categories; one is the demographic characteristics, the other is the benefit sought. The study on purchasing behavioral characteristics includes problem recognition, information search, alternative evaluation, purchase, ex post facto behavior after purchasing cultural tourism. The survey conducted from September 1th through 15th. Total of 300 questionnaires were distributed to the respondents in the selected 25 Gus in Seoul, and 245 were collected and 213 were usable and analyzed. The data analysis was done by SPSS Ver. 6.0 Factor analysis and cluster analysis were employed to find out the characteristics of segmented cluster; benefit sought. Cross tab and one-way ANOVA were used to present relationships among cultural tourists' selection features. Therefore, tourists behavior can be accounted to the benefits they want to obtain and market is required to be segmented by the benefits consumers want to obtain.

재배종과 야생종의 인공교잡 분리세대에서 주요형질들의 변이와 유전력을 조사하여 야생종을 이용한 콩 품종육성의 기초자료를 얻고자 수행한 결과를 요약하면 다음과 같다. 두 인공교배의 F_2 집단에서 100립중을 제외한 나머지 조사 형질들은 초원분리를 보였다. F_1과 F_2의 평균 개화일수는 양친의 중간정도로 정규 분포를 보였다. 백립중의 F_1 평균은 은하콩, 소백나물콩 두 조합 각각6.5, 5.7g으로 소립종 쪽으로 치우친 정규분포를 보였다. F_2의 평균수량은 양친의 중간정도이었다. F_1의 덩굴성은 두 조합 각각 6.4, 6.6이었으며 F_2 평균은 은하콩 조합이 6.0으로 덩굴성 쪽으로 치우쳐 덩굴성이 부분적인 우성으로 보였으나, 소백나물콩 조합에서는 4.6으로 은하콩과는 다른 결과를 보였다. 경장, 개회일수, 개체당 협수, 수량, 도복, 덩굴성 등은 높은 광의의 유전력을 보였으며 100립중은 협의의 유전력이 은하콩 조합에서 52.3%, 소백나물콩 조합에서 65.6%로 평가되어 초기세대에서의 선발이 가능한 것으로 나타났다. This study was conducted to obtain the information of varietal development using wild soybean through investigation of variation and heredity of major agronomic characters in F_2 generation of interspecific cross between Glycine max and G. soja. In segregating populations of two crosses, all characters observed except 100-seed weight showed transgressive segregation. Days to flowering showed normal distribution; mean days to flowering in F_1 and F_2 was approximately mean of parent. Mean of F_1 for 100-seed weight was 6.2g and 5.7g for Eunhakong/KLG10084 and Sobaegnamulkong/KLG10084, respectively, which were somewhat skewed distribution to small seeded parent. Mean of F_2 was about mean of two parents. Degree of vine was 6.4 and 5.7 in F_1 for two crosses but it was 6.0 in F_2 for Eunhakong/KLG10084, which revealed the degree of vine as partial dominance while 4.6 for Sobasgnamulkong/KLG10084, somewhat different results from the previous cross. Broad-sense heritability(h^2B) for plant height, days to flowering, pods per plant, seed yield, and degree of vine was comparatively high and narrow-sense heritability(h^2N) for 100-seed weight which is the most important character in the development of small seed-size sprout soybean was 52.3% and 65.6% for Eunhakong/KLG10084 and Sobaegnamulkong/KLG10084, respectively, which indicated that selection for the character in early generation was possible.

QFT를 이용한 전력 계통 안정화 장치 설계

이정필,정현화,김창현,정형환 동아대학교 정보기술연구소 2001 情報通信硏究所論文誌 Vol.8 No.2

In this paper, QFT robust control strategy is proposed to improve stability of power systems in the presence of parametric uncertainty. The basic idea in QFT is to convert design specifications of a closed loop system and plant uncertainties into robust stability and performance bounds on the open loop transmission of the nominal system and then to design a controller by using the gain-phase loop shaping technique. The robustness of the QFT controller has been investigated on a single machine infinite bus model by nonlinear simulations.
