The significant chemical constituents estimating the quality of green tea were compared and analyzed in the tea shoots of native Korean tea plants. The tea shoots of different varieties among native tea plants were plucked in Waun-ri, Yongjang-ri, others in eight tea-growing places, and Yabukita, for the comparison, which is excellent Japanese variety. The contents of Yongjang-ri tea shoots were 0.55% lower in total nitrogen, 41.44mg% lower in vitamin C and 0.56% higher in tannin than the average of the other eight places. The contents of ash, caffeine and water extract showed no difference between the tea shoots. Tea shoots of Waunri had similar compositions compared with those of Yabukita and other eight places in the chemical constituents. It is considered that the tea loaves in Yongjang-ri would be different variety comparing with other eight places in the view of characters and constituents. And it is thought that tea loaves in Waun-ri would be the large leaf variety of same genealogy because tea loaves in Waun-ri was different from the other eight places in characters, but was similar to in constituents.

Statement of problem: The introduction of "The Long-term Care Insurance System" (a public nursing care insurance scheme) is scheduled from July in 2008. Lately, the importance of oral health care had increased. Introduction and establishment of the methodology (nursing care procedure) based on professional dental knowledge is inevitable. Purpose: The purpose of this study was to rouse recognition of the importance of dental care in the long term elderly care in nursing homes, with implementation of the new insurance law. Material and methods: Visited two institutions for the elderly, Yudang Village and Sungjiwon located in Suwon city to investigate the present conditions in terms of (1) the detailsof the institution, (2) the activities concerning with dental care in the institution, and (3) the consciousness and recognition regarding dental care of the staffs. Results: In two institutions, under the present conditions, oral cleaning (including the cleaning of denture) for residents was operated with no professional advices and limited professional dental care. It was found that there was very little awareness of aspiration pneumonia. The members of staff however, did recognizethe necessity of professional maintenance and management of oral care in daily nursing care, and that many residents hold dental problems. They were very eager in introducing the methodology (nursing care procedure) in dental care in nursing homes.

This study examines the results of analyses of the lead isotope ratio and chemical composition of lead glass and green glaze from ancient Northeast Asia in order to suggest their production sites and reveal further characteristics. The comparison of the lead isotope ratio of lead glass and green glaze from two Baekje remains in Iksan-the Wanggung-ri Site and Mireuksa Temple Site-suggests that they were produced to the west of the South Gyeonggi Massif (Zone 4) using lead extracted from the same area. With a few exceptions, it has proved difficult to identify the production sites of most of the green-glazed roof tiles from Unified Silla-period Buddhist temples across Northeast Asia. The major component of the lead glass from Baekje, Silla, China, and Japan during the seventh century is PbO, SiO₂, Al₂O₃, CuO, and Fe₂O₃, with a ratio of PbO and SiO₂ of 70 and 30 wt.%, respectively. The green-glazed roof tiles excavated from a temple from the Unified Silla period have a high proportion of lead, ranging from 64 to 90 wt.%. Green-glazed lozenge tiles excavated from the Sacheonwangsa Temple site in Gyeongju were shown to contain PbO, SiO₂, Al₂O₃, and CuO, a similar composition with lead glass. An experiment was conducted to reproduce a glaze according to the production method mentioned in the Zō hotokesho sakumotsu-chō (Buddhist statue workshop crop book) in the Shosoin Repository. In this experiment, an identical ratio of PbO was observed for Japanese green-glazed ceramics from the eighth to eleventh century as that found in Chinese lead-glazed ceramics excavated from kilns operated from the seventh to tenth century in Henan. This indicates that production methods for lead glass and glaze were shared across Northeast Asia.

It is judged that celadons with '○' pattern and '⊙' pattern have the indication of manufacturer by engraving mark at the internal center of the bottom. These celadons were produced at No.8.23.27 kiln sites located at Sadang-ri(사당리), Daegu-myon(대구면), Gangjin-gun(강진군), Jeollanamdo(전라남도), Korea and '⊙’ patterned celadon porcelain was found only at No. 23 and 27 kiln sites, so it is assumed that its production sites were limited. Kinds of celadons included bowl, dish, cup, bottle, case and vessel for emptied wine and there were a lot of dishes with a variety of patterns. These celadons were engraved by molded design technique using the same ceramic design as the pattern of celadons in the period of their prosperity and it was appropriate method to produce celadons of a good quality with production method to keep decorative design like pattern or size uniformly. It was also found that inlay method was not universalized in this period and similar celadons were produced with molded design in large quantities. These celadons had partially fire clay temper, but most of them were burnt by supporting the inner bottom of U-type base with quartzite after whole glazing. It was known through relics excavated at Seokreung(석릉) royal tomb of King Heejong(희종) at Ganghwa(강화) and Hyeeumwon(혜음원) temple site at Paju(파주) and military house at Wakamiyaoji(약궁대로) avenue Kamakura(겸창)-city, Japan(일본) that these celadons were manufactured at two quarters of the 13th century centering around 1230s. Therefore, these celadons will be significant materials to fill the gap of the celadons in the 13th century resulted from the record chronologically that green celadons were manufactured in the 12th century. And this period was invaded by Mongolia(몽고), but central control was achieved and green celadons were continuously produced. It was also considered that these celadons were excavated at Gabgot-ri(갑곶리) and Gwanchung-ri(관청리), Ganghwa(강화), Hyeeumwon temple, Paju which played the role of temporary palace, Bu1guksa(불국사) temple at Gyeongju(경주), Silsangsa(실상사) temple at Namwon(남원) and relics of Jangheung(장흥) adjacent to Daeguso(대구소) and these were produced for high class.

A sampling survey was conducted at three reservoirs of Junam wetland ($6.02km^2$) in Korea to identify the wetland insect fauna along with their dominance, diversity, richness and evenness. Methods of monitoring were visual inspection and sweeping in 2010, Malaise trapping in 2011, light trapping and pitfall trapping in 2012. In total, 9,269 individuals (36.3% coleopterans, 21.3% lepidopterans and 13.9% odonates) were collected, belonging to 574 species, 141 families and 14 orders. For the number of species, lepidopterans shared the highest (31.2%), followed by coleopterans (28.0%) and hemipterans (12.9%). Dominant species were Enochrus simulans (Coleoptera) (7.9% of total individuals) followed by Hydaticus grammicus (Coleoptera) (4.3%), Galerucella nipponensis (Coleoptera) (4.1%), Elophila interruptalis (Lepidoptera) (3.1%) and Apis mellifera (Hymenoptera) (2.2%). Total counts of coleopterans, lepidopterans and odonates in the three reservoirs were quite high, but the counts were not significantly different among the reservoirs. Insect diversity index (H') and richness index (RI) of the Junam wetland were 5.04 and 59.10, respectively.

Asplenium yoshinagae (Aspleniaceae), previously known only from Japan, southwest China to Himalaya, was found in Gageo-do, Heuksan-myeon, Sinan-gun, Jeollanam-do. This species is similar to A. trichomonas, A. tripteropus, A. boreale, A. normale and A. oligophlebium by having gemmae and auricle of pinna, and distinguished from the latters by distinct stipe length, stalk of pinna, acute apex of pinna, length of indusium and shape of sorus. The Local name, Ga-geo-kko-ri-go-sa-ri, was newly given considering the locality. To reveal the interspecific relationships within the genus Asplenium in Korea, cladistic analysis was performed for 22 taxa of Asplenium as ingroup and 2 taxa of Diplazium as outgroup from Korea based on 20 morphological characters. As the results, the genus Asplenium seperated strongly from outgroup, and divided into 4 clades. Asplenium yoshinagae belong to the third clade. A. hondoense N. Murtakami & S. I. Hatanaka, which contained in the second clade, had treated as Hymenasplenium, but this results supported that this taxon may be contained in Asplenium, and also, Asplenium ruprechtii, not in Comptosorus. The morphological characters and illustrations of the species are provided together with photographs of habitat.

Currently, the natural monument system of Korea for naming and designation of natural monuments is based on "Chosun Natural Monument Conservation Acts for Treasure, Ancient Landmark, and Natural Beauty" enacted in 1934 during Japanese colonization period. The framework of natural monument system is still in effect, which is pointed out as a problem. The Dangsan forests and Bibo forests are Korean traditional cultural resources representing countryside of Korea. Cultural Heritage Administration follows and relies on the 'Limsu of Chosun' (1938), a report written by a Japanese, for naming and classification of natural monuments. A Dangsan forest at Yesong-ri was named "Yesong-ri evergreen forest" in 1938. They followed the naming system of "evergeen forest" until today. The objective of this study is to review the issues and problems of 'Limsu of Chosun' and natural monument naming system begun during Japanese occupation period, and suggest an alternative to the current situation where naming natural monument accordingly without discretion. Eighteen dangsan forests bibo forests were selected for examination and analysis. The names of the dangsan forests bibo forests were evaluated to find out whether various aspects of the forests are reflected in the name. The study suggests that many forests and old trees designated as natural monument should be named as "~Dangsan forest", "~Dangsan forest Bibo forest", or "~Dangsan tree" with consistency accordingly. The new names will bring a momentum to overcome the limitation of natural monument naming system continued since Japanese occupation period, and also enhance the value of Dangsan forests and Bibo forests as Korean traditional and cultural landscapes.
