  • Two-Color photoelectric observations were made at Flower and Cook Observatory, University of Pennsylvania. Since the spectroscopic elements are available for the system, derivation of an absolute physical dimension is now expected to be feasible. Results of computation of the orbital elements lead to a fact that the system shows an annular eclipse rather than a partial which is a finding reported by Shapley.

  • The purpose of this study was to investigate the functional properties of Changhoji with natural dyeing. This research would provide a basic information for interior material Changhoji. To estimate functional properties of super eight colors Changhoji, water staining, lightfastness, and floodlight color test were executed. In term of the water staining test, blue color showed the clear and other colors showed the little spot. As a result of measuring the lightfastness, Magenta color dyed with sappanwood showed the worst. But blue color dyed with indigo and Turquoise color dyed with indigo and Pagoda tree flower showed the highest. As a result of floodlight color test was no difference between sample color and floodlight color.

  • The purpose of this present study is not only to investigate mutal relationship between the preference of clothing design and the nature of Reflectiveness-Impulsiveness, but to offer clothing design for desirably developing of child, especially of preschool children. And the practical research was performed for 166 preschool children who are in kindergarten located in Seoul and are selected according to their sex and social class. This study used Kagan's MFFT and Personality Inventory of Hwang Eung-Yeon for the test of Reflectiveness-Impulsiveness, while for the preference of clothing design used the photo deck which is showed to children. The data analysis was based on frequency, percentage, mean, standard deviation, chi-square ($x^2$) test, t-test, F-test, and Duncan's Multiple Range Test. It can be concluded that girls rather than toys, high class children rather than middle or low class children were more reflective as a general trend. The relationship between the preference of clothing design and the nature of Reflectiveness and Impulsiveness is as follows : 1. In color, reflective boy liked blue series and reflective girl liked pastel coloring series, while they disgusted red series and non-coloring series. The group of impulsiveness liked red series, while they disgusted non-coloring series. 2. In color combination, group of reflectiveness liked similar color, while group of impulsiveness liked contrasting color. 3. In texture, group of reflectiveness liked soft and shiny texture, while they disgusted thick and rough texture. Also Group of impulsiveness liked soft texture. 4. In pattern, reflective boy liked lettering pattern and reflective girl liked flower pattern, while she disgusted lettering pattern. Impulsive boy liked stripe pattern and limpulsive girl liked flower pattern. 5. In pattern size, group of reflectivenss liked small size, while group of impulsiveness liked large one. 6. In style, group of reflectiveness liked formal style.

  • 고성능 카메라와 고용량 메모리가 장착된 스마트폰이 출시되어 사람들은 야외나 산에서 촬영한 아름다운 경치, 꽃 등을 SNS에 많이 올리고 있다. 본 논문에서는 이동통신이 원활하지 않은 곳에서도 꽃의 정보를 얻을 수 있는 꽃 인식 시스템을 개발한다. 개발된 시스템은 OpenCV를 기반으로 안드로이드 스마트폰에서 사용할 수 있으며, 기준 꽃등록부와 꽃인식부로 구성된다. 인식처리 시간을 줄이기 위하여 RGB 색채널과 k-평균 클러스터링을 이용한 새로운 색분류방법을 제안하고, 특징 추출을 위하여 ORB, 매칭을 위하여 브루트포스 해밍 알고리즘을 사용한다. 4부류의 12 종류의 꽃에 대하여 60개의 이미지를 기준 DB 설계에 사용하고, 60개의 이미지를 테스트에 사용하였다. 모의 실험 결과 성공률은 83.3%이고, 화웨이 ALEUL100 스마트폰에서 평균인식 시간은 2.58 s 이며, 제안된 시스템은 통신이 되지 않는 곳에서도 휴대용 스마트폰에 적용가능하다는 것을 확인하였다.

  • The Following is a list of specific external and internal morphology of Rheum palmatum L. and R. undulatum L. in Rhei Rhizoma. 1. For the original plants of Rhei Rhizoma in the literatures. 18 plants are reported. 2. The external characteristics of original plant : R. palmatum has a large palmate leaf, its petiole of radical leaf has a simple bristle and its flower is purple and pink color. Whereas R. undulatum has a medium ovate leaf, its petiole of radical leaf is purphish, its stem leaf surrounds a half of stem and its flower is yellowish white color. 3. The character of herbal states : a. diameter and size-- R. palmaum is bigger and heavier than R. undulatum. b. in section--R. palmatum is dark brown color, R. undulatum is bright brown color Fibrovascular bundle is arranged in circle shape in R. patmatum. R. undulatum shows a distingushed wheel shape. 4. The internal characteristics : R. palmatum has a large intercellular space of cork layer, its cambium is clear and a xylem medullary ray is comparatively tight, Whereas R. undulatum has a tight intercettular space of cork layer., its cambium is a few clear and xylem medullary ray is verty tight. As these results, additional study is required to distinguish herbs and their effect among many kinds of same genus-degree of relatedness.

  • Sorting cut roses according to quality is very essential to increase the value of the product. Many factors are involved in determining the grade of cut roses: length, thickness, and straightness of stem, color and maturity of bud, and extra. Among these factors, the stem straightness and bud maturity are considered to be difficult to set proper classification criteria. In this study, a prototype machine and an analysis procedure were developed to grade cut roses according to stem straightness and bud maturity by utilizing color image processing and neural network. The test results indicated 15.8% classification error for stem straightness and 10.0% for bud maturity.

  • To analyze molecular traits determining pigmentation between Pharbitis nill violet and white, Amplified Fragment Length Polymorphism(AFLP) and Differential Display Reverse Transcription(DDRT) experiments were carried out with either genomic DNAs or total RNAs isolated from both plants. Results of AFLP experiment in combination of 8 EcoRⅠ primers with 6 MseⅠ primers showed 41 violet-and 60 white-specific DNA bands. In the subsequent experiment, 22 violet-and 22 white-specific DNA fragments were amplified by PCR with DNAs eluted. The sizes of the fragments range from 200 to 600bp. DDRT using total RNA produced 19 violet-and 17 white-specific cDNA fragments, ranging from 200 to 600bp. The fragments obtained by both AFLP and DDRT had been cloned into pGEM T-easy vector, amplified and subjected to the nucleotide sequence analyses. As a result of Blast sequence analysis, most of them sequenced up to date showed no similarity to any Known gene, while few has similarity to known animal or plant genes. An AFLP clone V6, for example, has a strong sequence similarity to the human transcription factor LZIP-alpha mRNA and a DDRT clone W19 to Solanum tuberosum 3-hydroxy-3-methylglutaryl coenzyme A reductase mRNA.

  • 1999년 'Bristol Fairy' 유래의 결실되는 아조변이체 Gyp99 계통을 선발하였고, 그 계통의 실생 중 계통선발을 거듭한 결과 특성이 우수한 Gyp06-29 계통을 선발하여 2년간 특성 검정을 통해 'Dream Pink'를 육성하였다. 'Dream Pink' 품종은 중간형의 초형을 가지고, 소화는 꽃잎수가 많고 암술이 2개인 분홍 겹꽃이며, 꽃잎은 도란형, 꽃받침 모양은 종형인 식물체 고유특성을 갖는다. 또한 화경이 강하고 흰가루병에 매우 강하고 충해에도 강한 편이다. 여름절화 작형에서 'Dream Pink' 개화는 대조품종인 'My Pink'보다 5일 늦고 절간장과 화경장이 길었으며, 마디와 측지 분화가 많고 분지각은 작았다. 소화와 꽃받침 크기가 크고 꽃잎수가 많았다.
