      • 제6차와 제7차 교육과정에서 초등학교 과학 교과서 삽화 비교 분석 : Centered on the 3rd Year Class of the Elementary School

        남철우,권영길 光州敎育大學校 初等敎育硏究所 2002 初等敎育硏究 Vol.17 No.1

        This study was intended to examine the difference and the suggestion through comparative analysing the illustrations in the 3rd elementary science textbooks of the 6th with the 7th curriculum. The findings of this research were as follows. (1) Compared with the 6th curriculum, 448 more illustrations are presented in the 7th curriculum science textbook and the teacher's teaching techniques should be, therefore, improved the using ability of the illustration in the science education. (2) Although more than 96% of the illustrations are those of photographs and pictures in the 6th curriculum, those in the 7th consist of many kinds of the illustrations-photographs, picture, diagrams and cartoons. Especially, the more frequent introductions of the cartoons in the textbook give familiarity to the students, and it suggests that the textbooks were constructed in consideration of the student's intellectual development. (3) The roles of illustrations in the 6th and the 7th curriculum are mostly guidance for experiments and the supply of the learning materials. but considering that the learning motivation is very important in the teaching-learning process. the percentage of the illustrations in accordance with the motivations must be increased, (4) As the result of the analysis of illustration in the each domains, in the 6th curriculum there are the most numbers of illustrations in the biology domain and the least in the physics domain. But contrastively in the 7th curriculum there are the most in the energy and the least in physics, and namely those are distributed widely. (5) Analysing the kinds of illustrations in the each domains, in the both sixth and seventh curriculum the photographs are used in the physics mostly, and it is, therefore, interpreted because of the reason that the more realistic material supply should be needed. (6) According to the roles of illustrations in the each domains, there are the many illustrations for guidance of the experiments in the both curriculum, and contrastively in the biology part and the earth science, the many illustrations are introduced for material supply. In this viewpoint it is known that the illustrations of the physics domains and the energy are constructed for experiment, and those of the biology domain and earth science for investigation and observation of the given materials. (7) the average numbers of illustrations to be taught in a period or in a page are introduced more twice in the sixth text-book than the seventh. It is, naturally, concluded that the teachers' training process for using the illustrations is needed urgently.

        주사전자현미경을 이용한 토마토에 발생하는 아메리카잎굴파리(Liriomyza trifolii)의 외부형태적 특징

        윤영남,김기덕,박수진,김남성,서미자,채순용 충남대학교 농업과학연구소 2000 농업과학연구 Vol.27 No.1

        SEM을 이용하여 아메리카잎굴파리(Liriomyza trifolii)의 암 ·수컷 성충의 외부형태적 특징을 살펴보았다. 더듬이에 있어 감각모의 3가지 형태는 더듬이가는마디(funicle)에서 관찰되었으며, 모상감각기(trlchold sensillum)는 말단 부위가 뽀족한 특징적인 형태를 하고 있고 감각기들 중에서 가장 많이 분포하고 있다. 원추상 감각기(basiconic sensillum)는 길이가 13㎛, 지름이 1.4㎛에서 1.2㎛인 원형곡선형이다. 홈형 감각기(grooved sensillum)는 간상(peg) 끝에서 나온 손 모양을 하고 있으며, 이 모든 감각기들은 후각과 연관되어져 있는것으로 추정된다. 구기는 홉즙형으로 작고 펼쳐진 윗입술(labrum)과 합쳐져서 하나의 연결된 주둥이(rostrum)을 형성하고 있다. 가느다란 한 쌍의 작은턱수염(maxillary palp)은 긴 관 모양으로 각각의 세로로 이어져 있다. 발마디는 5마디로 이루어져 있으며 그 한가운데에는 패드모양의 흡착반(pulvillus)과 가시모양의 발톱사이돌기(empodium)가 있다. 아메리카잎굴파리는 흡착반과 발톱사이돌기에서 미끄러운 표면에 부착할 수 있는 물질을 분비한다. 수컷의 생식기는 매우 복잡하며 삽입구(aedeagus)는 생식기관으로서 가장 일반적인모양이다. 반면에 암컷의 생식기는 상대적으로 간단한데 이 구조는 외부로 돌출된 관모양이었다. 또한 이러한 결과를 이미 발표된 다른 여러 종의파리와 비교하였다. The external morphology of male and female of Liriomyza trifolii (Burgess) was studied using the scanning electron microscopy (SEM). Three types of sensilla were identified on the funicle of antennae. The trichoid sensilla were most conspicious and distributed with a characteristic sharp structure at the apical end. Basiconic sensilla were showed distal curvature about 13㎛ long and 1.2㎛ to 1.4㎛ in diameter. Grooved sensilla were showed a finger-like projections at the peg apex. The function of these sensilla likely to be olfactory. The mouthparts were adapted for sucking food, and formed a elongate rostrum which was incorporated with labrum. The labrum was a small and flap-like shape. The slender and paired maxillary palp seemed to combine with each other lengthwise to long tube. The tarsus typically consisted of 5 segments, which might be variously modified, principally by thickening or flattening. The segment healed a pair of claws. Beneath the claws, there was a pair of pad-like pulvillia and a bristle-like median empodium. L. trifolii secreted on the pulvillus and empodium an adhesive substance that enable them to cling to smooth surfaces. Male terminalia was complicated. The name 'aedeagus' seemed the best available general term for the copulatory organ, otherwise, female terminalia was usually relatively simple. This structure was reduced and formed a telescopic, eversible, and tubular ovipositor.

        This is one of the preliminary researches for preventing osteoporosis in women of before and after menopause. We examined 63 women of 46-60 age(1-3 grade students' mothers of P highschool in Pusan) in order to check the standard of primary factors and prevention about osteoporosis by analyzing the questionary which was written by them. As a result, we got the relationship among RF(Risk Factor), PF(Prevention Factor), Age and BMI of osteoporosis is as follows : 1. The relationship between PF and RF was-0..315 and R^2=0.100 at the properness exam of the model. 2. The relationship between BMI and RF was low as 0.076 and R^2=0.006 at the properness exam of the model. 3. The relationship between Age and RF was 0.226 and R^2=0.051 at the properness exam of the model. 4. The relationship between BMI and PF was low as 0.015 and the result of the properness exam of the model got no meaning as 0.000. 5. The relationship between Age and PF was -0.13 and R^2=0.017 at the properness exam of the model. 6. The relationship between Age and BMI was 0.233 and R^2=0.054 at the properness exam of the model. The above facts are presumed as the result of the questionary which has sample size and low distinction. So if these problems are improved in the next study, more meaningful result can be obtained.

        In Germany, community based daycare facilities has been supported by long term care policies since the 1970s. With the legislation of Care Insurance, those policy has been developed further. As the use of daycare facilities decreased and the financial burden for consumers increased, administrators of facilities has been seeking for innovative programs and management methods in order to improve the service. For the same reason, policy makers have been pursuing new regulations of architectural standards of facilities. By looking at legislations (i.e., Law of Care Insurance, Law of Heim, and DIN18025) that stipulate architectural standard of facilities in Germany, this study will identify the development process of architectural change of daycare facilities. In addition, the study aims to contribute to the discussion on the use of day care facilities in Korea in terms of the legislation of Care Insurance soon to be introduced.

      • 효모의 구성적 Promoter들에 의한 Inulinase 유전자의 발현

        남수완,김연희 동의대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.10 No.1

        To express constitutively the inulinase gene (INU1) of Kluyveromyces marxianus in Saccharomyces, cerevisiae, three yeast promoters such as GAPDH, ADH1 and ENO1 were connected upstream of INU1. The resulting plasmids, pYIGP, pADH1-INU, and pENO-INU were introduced to S. cerevisiae SEY2102 host strain, respectively, and then each transformants were selected by staining of colonies on sucrose-agar plate. When the yeast transformants were cultivated on 2% dextrose media, the total expression levels of inulinase reached to 1.11 unit/mL, 0.88 unit/mL, and 0.69 unit/mL for respective GAPDH, ADH1, and ENO1 promoter systems. On 4% dextrose media, however, the inulinase activities were observed at 2.00 unit/mL for pYIGP, 0.71 unit/mL for pADH1-INU, and 1.40 unit/mL for pENO-INU. This result indicates that the constitutive expression of INU1 was significantly affected by the initial concentration of dextrose and the promoter strength was in the order GAPDH, ENO1, and ADH1 promoter at high dextrose concentration. Taking into account the plasmid stability, however, it is suggested that the ENO1 promoter system is more suitable for the INU1 expression on high dextrose medium or in the fed-batch cultivation accumulating ethanol at high level.

      • 재조합 Saccharomyces cerevisiae에서 Inulinase와 Invertase의 발현과 분비에 미치는 배양조건의 영향

        남수완,신동하,김연희 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1

        The effects of medium pH and culture temperature on the expression and secretion and secretion of inulinase and invertase were investigated with recombinant Saccharomyces cerevisiae cells. These cells were obtained by transformation of 2μ-based plasmids pYI10 and pYS10 which contain Kluyveromyces marxianus inulinase gene (INU1A) and S. cerevisiae invertase gene (SUC2), respectively, in the downstream of GAL1 promoter. The expression level and localization of inulinase and invertase were not affected significantly by the initial medium pH: secretion efficiencies of inulinase and invertase into the medium were about 90% and 60%, respectively, in the pH ranges of 4.0 to 6.5. However, the expression and secretion of both enzymes were strongly dependent on the culture temperature. The highest expression (7.7 units/mL) and secretion (6.7 units/mL) of inulinase were observed at 28℃ and 30℃. As a consequence of decreased localization of inulinase in the periplasmic space, the secretion efficiency increased from 68% at 20℃ to 95% at 35℃. The total expression level and secretion efficiency of invertase increased from 19 units/mL and 55% at 20℃ to 25 units/mL and 68% at 35℃, respectively. Irrespective of the culture temperature, the invertase activity in the cellular fraction (periplasmic space and cytoplasmic fractions) was kept constant at around 33∼45%.

        박연식,김동준,황윤찬,황인남,오원만 大韓齒科保存學會 2006 Restorative Dentistry & Endodontics Vol.31 No.2

        본 연구는 레진 블록에서 엔진구동형 Ni-Ti 기구를 이용하여 근관성형 후 Buchanan plugger의 삽입 깊이에 대한 비교를 통해 임상적 상황에서 Ni-Ti 파일로 근관 성형 후 Continuous wave of condensation technique을 이용한 근관 충전시 적절한 크기의 Buchanan plugger 선택에 지침을 제공하기 위해 시행되었다. 만곡근관과 직선근관을 가진 레진 블록에서 ProTaper와 ProFile을 이용하여 근관 성형을 하였다. 성형 후 근관에 Buchanan plugger 가 근관벽과 처음으로 접촉하는 부위까지 삽입한 후 그 상태에서 스태너를 이용하여 이미지를 얻었다. 이미지 분석 프로그램을 이용해 근첨에서 plugger 첨부까지의 거리를 얻었다. 각 기구에 대한 plugger 삽입깊이에 대한 유의성을 검정하기 위해 one-way ANOVA를 시행하였고, 사후검정을 위해 Scheffe's test를 시행하였다. 본 연구의 결과 만곡되고 좁읍 근관에서, ProTaper F2와 F3로 마무리 성형한 근관에서 F. FM 크기의 plugger를 사용할 경우 Continuous wave of condensation technique으로 적절한 근관충전이 가능함을 시사하였다. This study was conducted to evaluate the insertion depth of Buchanan plugger after shaping by various Ni-Ti rotary files. It was conducted to determine which size of plugger are appropriate, when root canals are shaped with Ni-Ti rotary files and obturated by Continuous wave of condensation technique. Two type of eighty simulated resin blocks were used : J-shaped and straight shaped canal. The simulated canals were instrumented by ProTaper and ProFile. Buchanan pluggers were inserted into the canal, and then the image was recorded to scanner. The distance from the apex of the canal to the plugger tip was measured by image analysis program. Data were analyzed by one-way ANOVA followed by Scheffe's test. The results were as follows 1. In straight canal finished up to ProTaper F2 and F3 file, F and FM pluggers were inserted more than 5 ㎜ short of working length. 2. In J-shaped canal finished up to ProTaper F2 file, F pluggers were inserted more than 5 ㎜ short of working length. Finished up to ProTaper F3 file, F and FM pluggers were inserted more than 5 ㎜ short of working length. 3. In straight and J-shaped canal finished up to ProFile . 06/#20 and ,06/#25, any of Buchanan plugger could not be inserted more than 5 ㎜ short of working lenghth. These results suggest that canals shaped by ProTaper could be obturated by Continuous wave of condensation technique with F and FM size Buchanan plugger.
