Pumpkin has long been used as traditional health materials in oriental medicine, pharmacy, medicine, and food industries in many countries. In this study, the water extract and two active components from tendril of young C. moschata Duch. were investigated on inflammation inhibitory activity. The water extract of young C. moschata Duch. showed high cell viability over 95% and it decreased the production of interlukin 6 (IL-6) and tumor necrosis factor (TNF-${\alpha}$) in the capacity of mouse bone marrow-derived macrophages (BMDM) upon lipopolysaccharide (LPS) stimulation. Also, isolated fraction (B4) suppressed the secretion of IL-6 and TNF-${\alpha}$. Among the domestically cultivated pumpkins, B4 fraction contained in the tendril part of them and it comprised of the order of tendril from Cucurbita pepo var. cylindrica, old of C. moschata Duch., and young of C. moschata Duch. These results suggest that water extracts of C. moschata Duch. and purified active compound, rutin, show anti-inflammation activity by suppression of the secretion of IL-6 and TNF-${\alpha}$. It can be applicable as pharmaceutical materials.

Wild soybean plants(Glycine ussuriensis) collected from Korea(47 strains) and abroad(41 strains) were grown under field condition and classified according to the growth habit. Seeds were analyzed for protein content. The results were as follows: 1. Wild soybean plants were classified into three groups each by seed size, growth habit of stem, leaf size and flowering time. 2. Seed protein was higher in the strains with large leaves, tendril, stem or late flowering. 3. Glycine gracilis, supposed to be the intermediate species between cultivated and wild soybean(according to the stem growth habit, straight or semitendril, and seed size) was medium in protein content of seeds. 4. The average protein content of Glycine ussuriensis, 43.2%, was highest in comparison with those of others such as G. gracilis, 37.5%, or G. max, 36.2%. 5. One hundred seed weight of Amphicarpaea trisperm, similar to the wild soybean, was almost same as Glycine ussuriensis, but protein content of this species was lower than wild soybeans.

This study investigates the developmental pattern of adhesive discs (ADs) to highlight the ontogeny and structural changes that occur during the growth of Boston ivy. Initiation to postmortem features of ADs were examined through light and scanning electron microscopy. The study also reveals a new finding of the dislocation of peripheral tissues of adaxial origin. Four phases of attachment are suggested with regards to its climbing behavior: 1) pre-attachment, 2) upon attachment, 3) after attachment, and 4) final attachment. During initiation, several ADs originate from tendril primordia without epidermal differentiation. However, different growth rates in the epidermis results in completely different ADs. ADs were discerned by size, shape, and color during expansion, but cells in the adaxial surface remained alive longer than the other side. Upon contact, the ADs demonstrate simultaneous growth and deterioration, but once attachment is established the latter process subdues to final stages. Epidermal transformation, adhesive secretion, cellular disruption, and mechanical stress were essential for the self-clinging nature of Boston ivy. The post-attachment sequence is also believed to be critical in achieving maximum mechanical strength to provide extensive support. The developmental process of ADs is prompted by tactile stimulation but in a highly organized and systematic manner.

The yanggwan is a striped headpiece for civil and military officials worn with jebok, a costume for the royal ancestral worship ceremony, or jobok, a ceremonial costume for the courtier. It was called a jegwan when it was worn with a jebok. The geumgwan and jegwan are of the same style but the geumgwan has a gilded band and backside and the jegwan is mostly lacquered. The yanggwan was worn first with the jebok by the officials, both of which were received from the Chinese Ming dynasty in the 19th year of the King Gongmin's reign during the Goryeo period. The royal crown and court clothing system was two grades lower than the standard clothing code of the Ming dynasty of China. In the Joseon dynasty, the oyanggwan worn by the highest grade officials had five-stripes but was later replaced during the Daehan Empire by the seven-striped chilyanggwan used by Ming dynasty officials. Oyanggwans make up the majority of the surviving examples of these headpieces, with the exception of the six-striped yukyanggwan of Chung In-hak (1839-1919), the Minister of Justice, which originated in the Daehan Empire and whose owner is definitively known. The gilt portion of this yukyanggwan is finely engraved in relief with a bird, flower and tendril motif. The yukyanggwan is topped by a decorative bird ornament, called a jeongkkot. EDSS spectrum analysis of the gold plating reveals a composition of 51.32% gold and 10.34% silver. The yanggwan is composed of bamboo, mulberry paper and silk crepe. The black portions are lacquered. The individual yang is made with twisted mulberry paper.

More than 2,500 accessions of squash germplasm are preserved in the National Agrobidiversity Center of RDA, Korea. We investigated the ecological and morphological characteristics on 100 accessions of the squash germplasms with a low viability. Two typical types of oriental squash (Cucurbita moschata) and western squash (Cucurbita maxima) are possessed 89 and 11 accessions, respectively. The origin of 100 accessions was divided into three groups, group I (Korea landraces with 81 accessions), group II (Nepal with 15 accessions) and group III (Russia, Uzbekistan, Laos, and Mexico with each one accession). Seventy eight accessions germinated at $27^{\circ}C$ in growth chamber. Days to first flowering of the female and male flower ranged from 32 days to 67 days and 24 days to 55 days after planting, respectively. Vine length showed the largest variation ranging from 357.8 cm to 1,465 cm, also the average length of ten stem node range has a variable ranges from 92 cm to 217.5 cm. All regenerated squash accessions have an only collided tendril and have three to seven lateral shoots. The flattened globe-shaped squash is the most predominant and exhibited ordinarily round shaped, ball shaped, long oblong-shaped, elongated shape, and pear shape. The average weight of fruit ranged from 1.33 kg to 7.95 kg. Sugar contents showed 5.4~12.6 $Brix^{\circ}$ without ripening period.

The purpose of this study is to construct an evaluation criteria based on the relative importance and various combinations of each evaluation index and then to appraise urban biotope in terms of nature experience and recreation. After the standard of evaluation had been developed through the review of existing literature, the relative importance of the evaluation index through expert survey was determined, and the evaluation model to assess biotope value was established. The results of this study are as follows; 1) We have constructed the seventeen evaluation criteria through literature reviews, and have provided relative importance to each evaluation index of the natural in biotope, the diversity of landscape patterns, the appearance-existence of water space, the special landscape elements, and the access based on the results of expert survey. and then we have constructed an evaluation system using the relative importance criteria. 2) To evaluate urban biotope using the evaluation system constructed, we selected 14 sites. The final evaluation results of each site is as follows; The first grade areas are the water space with semi-natural style in front of Gangchon Woobang apartments, the forest zone near Page Temple at Mt. Palgong, the edge area of Jisan and Gosan and the tendril yard against Anshim middle school. The second grade areas are Hyomyung elementary school, the farm land behind the third Anshim Jugong apartment, Ehyun put and the swampy land in front of the Kangchon and Anshim construction site. The third grade areas are Seohan and Hwasung high-rise apartments at Beummul-Dong, the Korea Manpower Agency in the Sungseo industrial zone, and the adjacent area of St. Tongil. The only fourth grade area is the commercial zone near Taegu Department Store. 3) It is highly useful to evaluate urban biotope using the evaluation criteria constructed for this research, the evaluation criteria we developed may be difficult to encompass all expert opinion and the period of space-formation is difficult to estimate urban biotopes. In the future, it is necessary to gather the basic data suitable to estimate biotope and it is necessary to develop detailed evaluation criteria applicable to estimate every biotope that has specific property.

This study was conducted to obtain basic information on growth characteristics and major components of three Korean endemic resource plant species, Artemisia sp., Gynostemma pentaphyllum Makino and Humulus japonicus S. et Z. , growing in different areas in Korea. Three geographical types of artemisia, namely Pangssuk, Ongjinssuk and Yakssuk which were collect in Suwon, Ongjin and Eumsong, respectively were compared in yield, and Pangssuk artemisia was higher in yield than the others. However, essential oil content was the highest in Yakssuk artemisia. Dry weight of areal parts of G. pentaphyllum was higher in the cultural method with props for tendril growth than in the conventional cultural method without props. Rutin was detected in areal parts of G. pentaphyllum. Dry weight of areal parts of H. japonicus collected at the Kyeryong mountain in Chungnam province was higher than that collected in Eumsong. A phenolic compound isoquercitrin was detected in areal parts of H. japonicus.
