This review provides an overview of the published data on the canola meal and its suitability for duck as an alternative plant-origin protein source to soybean meal. Canola meal is a legume origin protein source containing comparable amino acid profile to soybean meal and rich in essential minerals and vitamins. Nonetheless, it is known to contain less in energy content than soybean meal. Factors like field conditions and processing methods creates compositional variations among canola meal. Presence of anti-nutritional factors such as phenolic substances, phytate and glucosinolates which are known to reduce growth performance in livestock animals, are the major drawbacks for canola meal to be a competitive plant-origin protein source in the feed industry. This review is focused to address i) nutritional characteristics and feeding value of canola meal for ducks and ii) impacts of feeding canola meal on performances of ducks.

The origin as well as the culinary aspects such as ingredients, types, preparation methods of Dasik and materials and ornamental patterns of Dasik mould(다식판) are discussed and analyzed through the literature survey. 1. The origin of Dasik came from the custom of Umdha(飮茶) together with the Worship of Buddhism(숭불정책) and the abundant production of rice due to the Policy for Agricultural Development(권농정책) of the Koryo Dynasty. 2. The main ingredient of Dasik was rice flour and wheat flour and thereafter, plant materials such as Song-wha(송화), Mungbean starch flour(녹두녹말가루) and Hwang-yul(황율) were followed. Honey, sugar and syrup were used as coagulating agents. Dasik was often colored by the addition of Omija(오미자), a plant material containing red pigment. 3. Originally. Dasik mould was not used until Jeungbo-Sanlim-Kyungje. Major types of Dasik were reviewed from the literature survey. 4. The materials of Dasik mould were wood or porcelain. Their shapes and ornamental patterns were reviewed. Circular design was predominant in the wood and lettered designs were predominant in porcelain. 5. Utilization of Dasik recorded in Koryo-History(고려사) and Chosun-Wangjo Shilloc(조선왕조실록) were reviewed.

'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

Objectives : The purpose of this study is to analyze the origin plants, the habitat and the characteristics of the origin-plants of the medicine herbs belong to Araceae. Methods : To achieve the purpose of this study 48 bibliographies about 4 kinds of herbs belong to Araceae were examined. The examination was focused on the origin plants, habitat, the efficacy. Standing on this analysis the list and characteristics of the origin-plants were presented. Results : The results indicated that 1. In the original plants of 4 kinds of herbs, there were 27 species of scientific name totally, 25 species belonged to Araceae, and 2 species didn't. The origin plants of Pinelliae rhizoma were 3 species of different family plant, 16 species for Arisaematis Rhizoma, 2 species for Typhoni Rhizoma, and 6 species for Acori Graminei Rhizoma. 2. In the view of its authenticity, there was one kind of genuine species, 2 species of substitutes in the origin plants of Pinelliae Rhizoma, 14 kinds of genuine species, 2 species of substitutes in the origin plants of Arisaematis Rhizoma, and Whole origin plants of Typhoni Rhizoma, Acori Graminei Rhizoma were genuine species. 3. According to the habitat, there were 15 species distributed in Korea, China and so on. And 16 species were distributed in Korea, 25 species were of foreign origin. 1 species was unknown. 4. The each efficacy of origin plants were reported in the main subject Conclusions : Among the 4 medicinal herbs in the commonly using family Araceae, there were 27 origin plants(25 species belong to Araceae, and 2 species doesn't), so the number of origin plants are almost 6.75 times compared with the cases of the herbal name. Also, according to the habitat, approximately 59.3% of origin plants were producted in Korea, and approximately 92.6% of origin plants were of foreign origin.

This report concerns the role of indole-3-acetic acid (IAA) in bacterial pustule disease of soybean. Pustule production in soybean leaves caused by Xanthomonas axonopodis pv. glycines was accompanied by a drastic increase in IAA content of host tissues. The phytopathogenic bacterium synthesized IAA in a tryptophan concentration-dependent manner when grown in a defined minimal medium. In complex media, however, the pathogen showed no response to tryptophan feeding, implying that the bacterial biosynthetic machinery of IAA is strictly regulated by nutrient availability of its growth environments. The results may suggest that IAA of bacterial origin and tryptophan of plant origin be involved in the process of pustule symptom development in soybean.

Polycyclic aromatic hydrocarbons(PAHs) in sediments of Kwangyang bay on Korea, have been investigated by gas chromatography-mass spectrometery (GC/MS). The average content of total PAHs in all samples was 2,211ppb, and the range was from 36 to 22,699ppb. The higher concentrations were found in sediment sampled near Kwangyang iron processing plant, Taeindo. The resulting distributions of PAHs according to the number of aromatic ring and molecular ratios of specific aromatic compounds (phenanthrene, anthracene, fluoranthene and pyrene) have been discussed in terms of sample location, origin of the organic matter. Four, five and six rings of PAHs were mainly found near to Kwangyang iron processing plant, and three and four rings near to Yeosu chemical kombinat This result typically indicated the local characteristics, depending on the origin of PAHs.

The early ontogeny of the vascular cambium in the hypocotyl of Eucommia ulmoides seedling was studied anatomically. In transverse view, the procambial cells repeated periclinal divisions and then gradually differentiated into vascular cambium; however, in the transectional plane, it was difficult to reveal the origin of cambial initials. In tangential view, the early procambial cells repeated periclinal divisions and then the procambium consisted of homogeneous short cells. Some cells in late procambium did not show transverse divisions, but elongated continuously. Thus, the procambium showed a heterogeneous structure: The long cells became fusiform initials with tapering end walls and the short cells differentiated into ray initials. Conclusively, the two types of cambial initials were gradually originated from the homogeneous cells at the early procambial stage, and they consisted vascular cambium.

Broussonetia × kazinoki Siebold has long been utilized as a major component in the manufacturing of Korean traditional paper, hanji, and has been suggested as a hybrid species of B. papyrifera and B. monoica. By applying three molecular markers, chloroplast (cp) ndhF-rpl32 IGS, a nuclear ribosomal internal transcribed spacer, and the TOPO6 gene, the hybrid origin of B. × kazinoki is tested. As a result, B. × kazinoki in Korea is demonstrated to be a hybrid of B. monoica × B. papyrifera, most likely formed naturally in Korea. The cp haplotypes detected provided information about the origins and genetic diversity of the maternal lineage B. monoica and paternal lineage B. papyrifera. The two nuclear markers were supplemented to each other, leading to the discovery of introgression in Broussonetia.

Gentic diversity of 42 isolates of Phomopsis citri was analyzed with random amplified polymorphic DNA(RAPD) and fungicide resistance. RAPD profiles of genomic DNA of the isolates of P. citri and the degrees of their resistance to the fungicides mancozeb and propineb suggested the occurrence of genetic differentiation of P. citri distributed in Cheju. The isolates showed genetically diverse RAPD profiles according to the host species collected even from the same collection site and also according to the geographic origin collected even from the same host species. High levels of resistance to fungicides mancozeb and propineb were observed among the isolates of P. citri. However, there was no correlation between RAPD profiles of genomic DNA and levels of fungicide resistance of the isolates, suggesting that fungicide resistance of P. citri occurred irrespective of the host and geographic origin.
