This study investigates, analyzes, and summarizes Dansplantation techniques and methods through practical methodology centering on fieldwork in order to present effective planting methods for large trees that have important significance. The conclusions are as follows : 1. The transplantation process of a large tree generally consists of the stages of digging up a tree, manufacturing a carrier frame, loading the tee on a vehicle, transporting, transplanting the tree, installing a strut and maintaining and managing the new transplant. In addition, planting a tree on a mounted place includes the primary procedures of trimming out the root, and preparing for transplanting the tree on a mounted place, as well as the secondary work of trimming out the root, transplanting a tree on a mounted place, maintenance and management. 2. In order to decide on a transplantation method for a large-sized tree, a structure calculation has to be performed first. That is, one must calculate the weight of the tree and the allowable stress of the strut (H-beam, etc.) fhst and then decide on the upper method through computer modeling based upon this structural calculation. 3. As a result of the analysis of a transplanted tree using the life soil method, it was confirmed that large quantities of feeder roots had developed around the root within a short time after the transplantation. The life soil method has proven to be very effective for transplantation of large-sized trees. 4. As for the production method of an H-beam strut frame, it was found that the manufacturing process and disassembly process were simple and proper; therefore, the H-beam frame is an appropriate structure to be used in the transplantation of large trees. 5. The concavo-convex method, which consists of filling the life soil in the concavo-convex area around the root, was found to be a method that promotes the growth of feeder roots within a short period of time and saves the supply of water at the same time.

It is well known that the fruit of the vitamin tree (Hippophae rhamnoides L.) provides excellent anti-diabetic, antibacterial, immune regulation, anti-inflammatory, and anti-aging effects. In some countries including Europe the fruit has been added to certain foods to develop functional foods. The present research was carried out to elucidate the biological function of vitamin tree fruit powder added to fermented milk. It was found that there was an antioxidant effect of yoghurt made with vitamin tree fruit powder, and this effect was greater with increased incubation time and amount of vitamin powder, as shown by 1,1-diphenyl2-picrylhydrazyl (DPPH) and 2,2-anziobis (3-ehtylbenzothiazoline-6-sulfonic aicd) (ABTS) radical scavenging activities. The antibacterial effect of yoghurt containing vitamin tree fruit powder was shown to be effective against four pathogenic microorganisms, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonela Typhimurium. In particular, yoghurt supplemented with 5% of vitamin tree fruit powder showed the best antibacterial effect. The yogurt containing the vitamin tree fruit powder significantly inhibited the expression of the anti-inflammatory cytokines interleukin (IL)-6 (yogurt [Y] + Hippophae rhamnoides L. powder [HP] and yogurt containing 5% Hippophae rhamnoides L. powder [HPY]) and IL-1β (HP, Y + HP and HPY) in a concentration-dependent manner among tumor necrosis factor (TNF)-α, IL-6, IL-1, and induced nitric oxide synthase (iNOS). Our results clearly demonstrated that vitamin tree fruit powder could be a good functional ingredient for improving health through yoghurt manufactured with vitamin tree.

The tulip tree ($Liriodendron$ $chinense$) has been widely cultivated in Korea as a street or garden tree for its large flowers, which have a superficial resemblance to tulips. Occurrence of anthracnose disease on the leaves of tulip trees growing on the campus of Gyeongsang National University, Jinju, Korea, has been observed. Based on mycological characteristics, pathogenicity, and internal transcribed spacer sequence, the causal fungus was identified as $Colletotrichum$ $gloeosporioides$. This is the first report on anthracnose disease caused by $C.$ $gloeosporioides$ on tulip trees in Korea.

In this study, 160 tea tree (Camellia sinensis L.) lines were classified by caffeine content using colorimetric methods. Among them, caffeine-rich lines (HR-78, HR-137, HR-82 and HR-123) and poor lines (HP-85, HP-88, HP-19, and HP-131) were selected. To know the difference in morphological and genetic characters between caffeine-rich and poor lines, we used leaf/shoot growth and RAPD methods. Cluster pattern of morphological characters (leaf width, leaf length, leaf area and shoot length) showed that shoot length was longer in caffein-rich lines than in -poor lines. In genetic analysis, amplified DNA bands having various sizes were detected in RAPD analysis where 30 random primers were used. However, the discriminated primer set that distinguish caffein-rich tree line from -poor lines was not found. These results can be used as the basic data to determine the morphological and genetic differences among caffein-rich and -poor lines.

국내에 충분히 보고되지 못한 소재로서 drumstick-tree (Moringa Oleifera Lam.)를 고부가가치 식품 자원으로서 그 활용가능성을 알아보기 위해 주요 영양성분 분식 및 in vitro 신경세포 보호효과에 대해서 연구하였다. Drumstick-tree의 주요 무기성분으로는 칼슘으로 2658.67 mg/100 g이 함유되어 있었고, 다음으로 칼륨, 마그네슘 및 인 등이 함유되어 있었다. 주요 지방산으로서 포화 지방산으로는 palmitic acid (16.33%)와 불포화 지방산으로서 gadoleic acid (66.34%)가 상대적으로 많이 함유되어 있었고, 지용성 비타민인 vitamin E가 94.78 mg/100 g 그리고 niacin이 112.61 mg/100 g 함유되어 있는 것을 알 수 있었다. 80% methanol에 추출한 drum-stick-tree 추출물을 활용하여 $H_2O_2$ 처리한 PC12 cell 내의 활성산소 생성억제효과를 DCF-DA assay를 통해 측정한 결과 drumstick-tree 추출물은 농도의존적인 활성산소 생성 억제효과를 보였다. MTT assay를 이용하여 $H_2O_2$로 유도된 PC12 신경세포에 대한 보호효과를 측정한 결과 vitamin C group 대비 효과적인 신경세포 보호효과를 확인하였고, LDH release assay를 통해 일정 수준의 세포막 보호효과를 역시 확인하였다. 또한 PC12 cell의 oxidative stress-induced apoptosis에 대한 세포 보호효과를 측정하기 위한 caspase assay 실험 결과, 세포 내 caspase activity가 추출물의 의해 효과적으로 감소됨을 알 수 있었다. 결국 본 연구결과를 종합해 볼 때, 우수한 영양 구성 성분과 함께 신경세포 내 oxidative stress의 저감화 등을 통한 drumstick-tree 추출물의 신경 세포 보호 효과는 고부가가치 천연 소재로서의 다양한 산업적 활용 가능성을 암시하는 것으로 판단된다.

For evaluation of immune stimulation effect of lacquer tree extracts, lymphocytes were counted by labeling of FITC-conjugated monoclonal antibody in the pheripheral blood of pigs that fed with a fodder supplemented by lacquer tree extracts. Populations of MHC-II+, CD4+, and CD8+T lymphocytes were increased more than 2% level after 1 week feed supply of the lacquer tree extracts. The increase of those T cells reached at maximum level after 2 weeks in the tested group. B lympyocytes with surface IgM were increased 5% after 1 week feed supply of the lacquer tree extracts, and their numbers reached maximum after 2 weeks in the tested group. For the assessment of cytotoxicity of the lacquer tree extracts, morphological changes were examined on the epithelial cells of small intestine from pigs fed with a fodder supplemented by 0.1 % lacquer tree extracts for 6 weeks (the tested group). Thin-sectioned tissue of small intestine was fixed with glutaraldehyde, then coated with gold particles, and the specimen was examined under scanning electron microscope. The villi on the mucus membrane of jejunum and ileum from the tested pigswere enlarged on the tip and were linked each other.

Suhainmyuldo(수하인물도) is a kind of picture which express a person under the tree and is known to be transmitted from the Middle Asia. The origin of this kind of expression is assumed to be from Iykshini(=Iygsha), the fairy of tree, in India of from the 'Tree of Life' in W. Asia, and they had in fluenced on the craft art design of Chinese art. However, Chinese art had already developed the motif of this kind in its unique way. For example, Jookrimchilhundo(죽림칠현도: seven wise men in bamboo forest), during Six Dynasty. The tree of life(arbor vitae, lignum viate), the origin of the Painting of figure under a tree(수하인물도), was spreaded in several regions around the center of Mesopotamia early, and them transmitted to Sasan dynasty of Persia, even to Islam, Byzantine, Romanesque, ancient East Asia. The mural painting found in the 4th Tongu Ogoe tomb, which was created after the 5th Tongu Ogoe tomb, used Obangsaek more than the 5th tomb painting did. (The term Obansaek refers to the five Korean traditional colors consisted of yellow, blue, white, red and black) The mural painting on the 4th Ogoe tomb employed distinct technique to depict an object in a certain color by painting the surroundings with different primary colors, making the painting look more exotic and mysterious.

It is well documented that the fruit of the vitamin tree, which is rich in vitamins A, C, E, and K, shows anti-diabetic, antibacterial, immune regulation, anti-inflammatory, and anti-aging effects. In some countries including Europe it has been used to develop various functional foods. This study was conducted to elucidate the fermentation properties of fermented milk supplemented with vitamin tree (Hippophae rhamnoides L.) fruit powder. The pH, titratable acidity, number of viable cells, and viscosity of the yogurt made with vitamin tree fruit powder were found to be higher than those of the control group, as the amount of supplemented powder added became higher and the fermentation progressed. Production of lactic, malic, and acetic acids increased relative to that of the control as the amounts of supplemented powder were higher. It was found that the increase in the decomposition of lactose to glucose and galactose was proportional to the amount of supplemented powder added and the elapsed fermentation time. During storage for 15 days the quality of yogurt supplemented with vitamin tree fruit powder was within the proper range of fermented milk quality in terms of pH, titratable acidity, and number of lactic acid bacteria. The yoghurt manufactured with vitamin tree fruit powder has a similar quality to that of the control, and therefore, a new functional yoghurt providing health benefits could be developed.
