Given the flow matrix, plant size and department sizes, the algorithms in this paper provide the layout with rectilinear distance. To construct automated facility design, cut tree approach is employed. A branch and bound computer code developed by Tillinghast is modifided to find the feasible fits of departments without shape distortion in the plant rectangle.

Given the flow matrix, plant size (rectangle shape) and department sizes, the algorithm in this paper provides the plant layout with rectilinear distance measure. To construct automated facility design, eigenvector approach is employed. A branch and bound computer code developed by Tillinghast is modified to find the feasible fits of departments without shape distortion (see [1])in the plant rectangle. The computational results compared with CRAFT are shown.

본 연구에서는 초 중등학교의 전 교과에서 다루어진 식물 학습 소재의 다양성을 조사 분석하여 과학 교과서(생물영역)의 식물 학습 소재의 개발 방향성을 모색하고자 하였다. 분석에 사용된 교과서는 초등학교 9교과 143권, 중학교 13교과 117권, 고등학교 15교과 71권 등 총 331권이다. 본 연구의 결과는 다음과 같다. 1. 초 중등학교 전 교과의 학교 급간별 식물의 종 수는 초등학교 264종, 중학교 295종, 고등학교 283종으로 과학교과서(생물영역)의 103종, 206종, 193종보다 많다. 타 교과에 식물의 종 수가 많다는 것은 식물 학습 내용도 많이 포함하고 있다는 것을 의미한다. 2. 초 중등학교에서 식물 학습 소재가 많이 나타난 타 교과는 국어, 사회, 실과(실업 가정)로 단순한 식물 인용뿐만 아니라 과학 개념 및 탐구 활동을 내포하고 있다. 식물 학습 소재는 과학 교육 과정뿐 아니라 학교 교육 과정에서 큰 비중을 차지하고 있다. 3. 타 교과에서 인용되는 식물 학습 소재의 특징은 주변 식물, 자원 식물, 식용 식물, 관상 식물, 산업에 관련된 식물 등 유용성 있는 생활 관련 식물이다. 4. 과학과 생활과의 관계를 인식하여 타 교과의 식물학습 소재를 과학 교과(생물영역)의 식물 소재 개발에 적용한다면 STS 교육 및 통합 교과의 근거를 제공해 줄 수 있다고 본다.

본 논문의 목적은 4학년 과학 식물의 한살이 단원의 교육용 어플리케이션을 현재 교육과정에 기반을 두고 설계 및 구현하여, 교사가 수업과 과제활동에 직접적으로 편리하게 활용하고, 4학년 학생들의 식물 학습에 실질적인 도움을 주고자 하는 것이다. 이 어플리케이션을 활용하여 교사는 식물의 한살이 단원에서 오프라인 수업과 모바일 학습을 결합한 블렌디드 학습을 구현할 수 있고, 이를 통하여 학생들은 학교에서 배운 내용을 언제, 어디서든 복습하고, 어플리케이션을 이용하여 과제활동을 수행할 수 있다. 이와 같은 학습 방법은 학생들의 학습 동기를 증가시키고, 학습의 재미를 더하여 식물의 한살이 단원의 학습효과를 향상시킬 수 있을 것으로 기대된다.

Arbuscular mycorrhizal fungi (AMF) have mutualistic relationships with more than 80% of terrestrial plant species. This symbiotic relationship is ancient and would have had important roles in establishment of plants on land. Despite their abundance and wide range of relationship with plant species, AMF have shown low species diversity. However, molecular studies have suggested that diversity of these fungi may be much higher, and genetic variation of AMF is very high within a species and even within a single spore. Despite low diversity and lack of host specificity, various functions have been associated with plant growth responses to arbuscular mycorrhizal fungal colonization. In addition, different community composition of AMF affects plants differently, and plays a potential role in ecosystem variability and productivity. AMF have high functional diversity because different combinations of host plants and AMF have different effects on the various aspects of symbiosis. Consequently, recent studies have focused on the different functions of AMF according to their genetic resource and their roles in ecosystem functioning. This review summarizes taxonomic, genetic, and functional diversities of AMF and their roles in natural ecosystems.

Cudrania tricuspidata Bureau is a widely-used, medicinal, perennial and woody plant. Obtaining information about the genetic diversity of plant populations is highly important with regard toconservation and germplasm utilization. Although C. tricuspidata is an important medicinal plant species registered in South Korea, no molecular markers are currently available to distinguish Korean-specific ecotypes from other ecotypes from different countries. In this study, we developed single nucleotide polymorphism (SNP) markers derived from the chloroplast and nuclear genomic sequences, which serve to to identify distinct Korean-specific ecotypes of C. tricuspidata via amplification refractory mutation system (ARMS)-PCR and high resolution melting (HRM) curve analyses. We performed molecular authentication of twelve C. tricuspidata ecotypes from different regions using DNA sequences in the maturaseK (MatK) chloroplast intergenic region and nuclear ribosomal DNA internal transcribed spacer (ITS) regions. The SNP markers developed in this study are useful for rapidly identifying specific C. tricuspidata ecotypes from different regions.

Antifungal activity of Korean and Chinese lichen-forming fungi(LFF) was evaluated against plant pathogenic fungi of Botryosphaeria dothidea, Botrytis cinerea, Diaporthe actinidiae, Pestalotiopsis longiseta, Pythium sp., Rhizoctonia solani, and Sclerotium cepivorum. The LFF were isolated from Cladonia scabriuscula, Melanelia sp., Nephromopsis asahinae, Nephromopsis pallescens, Parmelia laevior, Pertusaria sp., Ramalina conduplicans, Ramalina sinensis, Ramalina sp., Umbilicaria proboscidea and Vulpicida sp. with discharged spore method. The isolates were deposited in the herbarium of Korean Lichen Research Institute(KoLRI) in Sunchon National University. The LFF of Melanelia sp., P. laevior, Pertusaria sp., R. conduplican and Ramalina sp. exhibited strong antifungal activity against all of the pathogenic fungi examined. Among them, LFF of P. laevior showed more than 90% of inhibition in fungal hyphae growth, compared with control. The results imply that LFF can be served as a promising bioresource to develop novel biofungicides. Mass cultivation of the LFF is now under progress in laboratory conditions for chemical identification of antifungal substances.

Tea polysaccharide had high antioxidant activity and it could be used to cure diabetes. Antioxidant activity of tea poly-saccharide (TPS) from three kinds of tea (green tea, oolong tea and black tea) were compared, the result indicated that oolong tea polysaccharide (OTPS) had the highest antioxidant activity. In order to explicate the mechanism of antioxidant and hypoglycemic activity, the streptozotocin (STZ)-induced diabetes mice model (DM) was established. The influence of OTPS on blood-glucose, content of MDA and NO, and activities of GSH-PX, SOD, NOS in serum, kidney and liver were investigated. The result showed that after four weeks injection of OTPS to DM mice, the blood-glucose of three treatment group reduced by 14.5%,21.5% and 33.3%, respectively, comparing to the model control. The reduction effect of OTPS increased with the rise of dose. The activity of SOD and GSH-PX elevated significantly, while the activity of NOS decreased. The content of MDA and NO reduced significantly. The above results imply that antioxidant activity was enhanced. Comparing to XKW treatment, the effect of a dose of 300mg/(kg. bw) OTPS was much better. The research showed that the OTPS had a significant effect on reducing blood glucose, and could enhance the antioxidant activity of DM mice.
