The paper introduces the an necklace type UHF RFID tag for a live tree having high dielectric constant. When a general UHF RFID tag is used for the metal and the material with high dielectric constant, the electrical characteristics and impedance of antenna have been changed, and the tag is not recognized by an UHF RFID reader. The necklace type UHF RFID tag has been designed with consideration of the high dielectric constant of the tree material. The name tag for a live tree has been designed with the developed tag antenna. The performance of tag has been measured and the reading range is about 4~5m. The developed UHF RFID tag antenna can be applied to any high dielectric material for various industrial applications.

The purpose of this study is to examine how many plant names elementary school children how, and what kind of criteria they use for classifying these plants. The sample involved 926 students from the 2nd, the 4th, and the 6th grades dwelling in one urban, three suburban, and six rural areas. Their level of perception on the name of plants increased in correlation to the elevation of the grade level. However, different patterns of increases were shown depending on the local environments in which they live. The most well-known plant names for students were the rose of Sharon, the rose and the pine tree. The students mostly classified the plants using the following criteria such as 'with or without flower' and 'edible or inedible' regardless as to whether they had prior loaming experience of plant classification. 65.3% of the 6th graders correctly grouped 5 kinds of plants into the flowering and the non-flowering plant categories at the 1st level of classification. However, only 17.9% and 7.7% correctly divided the flowering and the non-flowering plants into two subgroups at the 2nd level of classification respectively. Therefore, their abilities in plant classification was shown overall to be poor. The students living in suburban areas appeared to be harmonized with both the natural and urbanized surroundings and classified the plants more scientifically than those from the urban or rural areas were able to. This suggests that the conception of plant classification by children is affected by the environment in which they live. If children have more opportunities to observe plants in surroundings such as their classrooms and school gardens, it will help them to form the relevant scientific concepts as well as to correct any alternative conceptions related to classification.

The observation of the classic plant name 'Hwe', that is to be discussed in this thesis, must be primarily conducted in folk plant research made through old documents. Diverse information such as the characteristics, method of use, and distribution of plants is scattered in old documents. However, reviews of classic plant names should be made to use such information. This is because information on plants can only be used after thorough verifications are made of the plant names. 'Hwe' is interpreted as various meanings in Korea but it is mostly used to mean fir, old pine tree, and cypress. However, it is not known by what standards such interpretations have been made. In particular, 'Hwe' is interpreted at the discretion of the translator in classic translations, so direct quotations from these lead to further errors. Therefore, items in classic plant names must be reviewed again. Why is 'Hwe' interpreted in various ways as a plant name and according to what standards should it be interpreted? This study was conducted with these questions. Also, the significance of this study is placed in the setting of guidelines for the interpretation of 'Hwe' so that classic plant names can be properly interpreted and information on plants can be accurately secured.

In an "NTFS Index Record Data Hiding" method messages are hidden by using file names. Windows NTFS file naming convention has some forbidden ASCII characters for a file name. When inputting Hangul with the Roman alphabet, if the forbidden characters for the file name and binary data are used, the codes are convert to a designated unicode point to avoid a file creation error due to unsuitable characters. In this paper, the problem of a file creation error due to non-admittable characters for the file name is fixed, which is used in the index record data hiding method. Using Hangul with Roman alphabet the characters cause a file creation error are converted to an arbitrary unicode point except Hangul and Roman alphabet area. When it comes to binary data, all 256 codes are converted to designated unicode area except an extended unicode(surrogate pairs) and ASCII code area. The results of the two cases, i.e. the Hangul with Roman alphabet case and the binary case, show the applicability of the proposed method.

'Mansoo' is a late-season pear cultivar with extra large and high quality fruit of long storability, which was released by National Horticultural Research Institute in 1995. The cultivar originated from the cross between 'Danbae' and 'Okusankichi' at Suwon in 1978, had been under regional adaptability test at nine areas in the name of 'Wonkyo Na-15' for 4 years since 1992. It was vigorous in tree growth and upright in tree shape. Its flower bud is easily maintained, resulting in higher productivity than 'Danbae' and 'Okusankichi'. It bloomed a day later than 'Niitaka', and showed cross-compatibility with 'Niitaka', 'Chojuro' and some other varieties. Harvesting time of 'Mansoo' is late October in Suwon. The fruit shape is oblate and skin color is light yellowish brown. The fruit weighed 600-700 g and has 12-13% soluble solids content. The flesh is soft, juicy, and has negligible grit. It is resistant to black leaf rot (Alternaria kikuchiana Tanaka).

Biological control of blue stain fungi, such as Ophiostoma and Leptographium spp., that reduce the quality of logs and cause economic losses in wood product industry, was carried out in laboratory and field trials by a colorless strain of Ophiostoma quercus, BSFcs-1. Inoculation of pine wood chips with the colorless strain 1 wk before inoculating wild-type strain demonstrated that BSFcs-1 colonized wood chips and excluded blue stain fungi from being established. Efficacy of BSFcs-1 was compared with colorless strain of O. piliferum, which is commercially available under the trade name of Cartapip. Inoculation of pine wood logs with the colorless strain 1 wk before inoculating wild-type strain of blue stain in isolated wood chips, while O. quercus and O. floccosum colonized 0% and 17%, respectively. Simultaneous inoculation of logs with the colorless and wild-type strains resulted in decreased colonization (28%) by BSFcs-1, but increased colonization by O. quercus (185) and O. floccosum (29%). On the other hand, BSFcs-1 and wild-type strain alone colonized 75% and 71%, respectively. Treatment of the surface of log ends with mycelial suspension of BSFcs-1 after cutting also showed good control of blue stain fungi in a pine forest stands.

Hand gesture is one of the most popular communication methods in everyday life. In human-computer interaction applications, hand gesture recognition provides a natural way of communication between humans and computers. There are mainly two methods of hand gesture recognition: glove-based method and vision-based method. In this paper, we propose a vision-based hand gesture recognition method using Kinect. By using the depth information is efficient and robust to achieve the hand detection process. The finger labeling makes the system achieve pose classification according to the finger name and the relationship between each fingers. It also make the classification more effective and accutate. Two kinds of gesture sets can be recognized by our system. According to the experiment, the average accuracy of American Sign Language(ASL) number gesture set is 94.33%, and that of general gestures set is 95.01%. Since our system runs in real-time and has a high recognition rate, we can embed it into various applications.

Recently, researches are studied in developing efficient techniques for accessing, querying, and managing XML documents which are frequently used in the Internet. In this paper, we propose a new method to cluster XML documents efficiently. An element of a XML document corresponds to a node of the corresponding tree and an inclusion relationship of the document corresponds to a relationship between parent and child node of the tree. Therefore, similar XML documents are similar to the node's name and level of the corresponding trees. We make evaluation function with this characteristic to cluster XML documents by genetic algorithm. The experiment shows that our proposed method has better performance than other existing methods.

This research is basic research about 「the afforestation project of the Shilla Dynasty's capital forest」 which is controlled by the research institute of forest and environment of Kyungbuk province. The results of the investigation about target places and selection of major species of trees is as follows. 1. In the Shilla Dynasty's times, the peach tree was the indicator of unusual changes in weather, and was also the symbol of unsurpassed beauty. Peach trees were so prevalent that people called the forest peach-hill or peach-forest. Therefore, the main tree of Shilla Dynasty's capital forest would have to be a peach tree. 2. From several records, pine and bamboo were planted or grown together. The pattern of planting trees like this case is also historic, so should be utilized positively. 3. In order to afforest the capital forest, the bamboos have to be planted on Nam-mountain in Kyung-ju, and maple trees have to be planted on Kumgang mountain. 4. There were many big trees during the Shilla Dynasty, and the name of one of the Six Main Villages was 'Big Tree Village'. Therefore, big and long-lived trees have to be planted also. 5. The willow tree has to be considered for afforesting the capital forest even though the willow trees are misunderstood to cause allergies. They are traditional landscape architecture trees. In the traditional literature, the willow tree stands for good news. 6. Japanese cornellian cherry(Cornus officinalis), which is related with old narrative literature in the era of King Kyungmun, has to be planted for the forest, and has to be considered to be an educational tree. 7. Korean Rhododendron, which is related with Madam Suro's story, has to be planted in stone gardens.8. Lotus, Korean pulsatilla, Boxwood, Bombycis Mulberry, and Japanese Apricot have been recorded just one time, but these are also important plants which have to be reflected on afforestation of capital forest project. 9. The forests of Shilla on the old records exist in 17 places. The afforestation project has to be undertaken at these places. 10. The people of Shilla deified the forest and trees, which were the places where ancestral rites had been performed. For example, Gyerim, Sinyurim, and Wanggasu were the sacred forests of the capital forest.
