The objective of this study was to investigate the sensory quality characteristics of coffee under various processing and roasting conditions of green beans. Colombia green bean samples were obtained from three processing methods: natural, pulped-natural, and washed methods. The green beans were roasted differently according to Agtron number: light (Agrton #65), medium (Agtron #55), and dark (Agtron #45). Moisture content, density, color value, pH, and total dissolved solid contents (TDS) were measured, and quantitative descriptive analysis (QDA) with 23 sensory attributes was performed for nine coffee samples. Hunter L values were significantly elevated with the degree of processing but reduced with roasting intensity. The pH values of the nine coffee samples were 5.6~6.2 and significantly increased with intensity of roasting. TDS decreased with an increase in processing and increased with roasting intensity. QDA results show that smoky aroma and nutty and chocolate flavor significantly increased while fruit and floral aroma decreased with intensity of processing. The attributes of brownness, oily surface, smoky aroma, bitter and burnt flavor, and greasy and heavy mouthfeel significantly increased while fruity and floral aroma, black tea, sour and umami flavor, pureness, and softness decreased as roasting intensity increased. Principle component analysis showed the overall significant relationships between 23 sensory attributes and nine coffee samples under different processing and roasting conditions.

The purpose of this study is to fiure out the floral changes during three years after construction of the Youido Ecology Park. Yearly change of plant species composition, distributed at the research field, had been investigated for three years since 1996. To compare and investigate the changes of the establishment of the Ecology Park, we have analyzed the distribution characteristics of plant species, exotic naturalized species, and so on. The results obtained through this investigation are as follows; 1) Total numbers of plant species were 106, 170, 175, and 148, in the year of 1996, 1998 1999, and 2000, respectively. While the most of cultivated species before th establishment were decreased, the naturalized species such Phargmites communis Trin, and Artemisia selengensis Turcz. etc, were increased. 2) Forty three species of exotic naturalized species were investigated and were increased at the early stage of the establishment, but showed decreasing trend recently. 3) Sixty five species of introduced and planted species were investigated. Most of them were occurred at the first year after the establishment, but since 1999, there has been a significant decrease. 4) Sixty seven species among total 235 were verified as the wetland-adapted plants. The ratio to the total numbers were low, but the occupied area of a few species was expanded. Therefore, it indicates that monitoring on the physical environments of the Youido Ecology Park was urgently required.

Several growth characteristics of two ornamental tobacco species, Nicotiana sanderae and N. affinis, were investigated in this study. Also effect of temperature and daylength on the flowering of the tobacco plants were evaluated to obtain basic information on breeding and cultivation. 1. The plants were great in high temperature-long day at the early stage and in low temperature-short day at the late stage of plant growth, for both Nicotana species. At the early growth stage the leaf length N. sanderae was great in high temperature-long day, and that of N. affinis was great in high temperature-short day period, while at the late stage of the plant growth the leaf lengths were more significantly effected by the temperature rather than daylength. Leaf width and leaf shape index were less sensitive to the conditions. 2. For both of the species, the total number of tobacco leaves not much influenced by the temperature and daylength. 3. There were no significant differences for budding and flowering period between the two species, both of which were sensitive to temperature and daylength with more influence by daylength than temperature. 4. Number of floral stalks, number of flower and flowering period were not much influenced by temperature and daylength; however, N. affinis had 2 more floral stalks, 31 more flowers, and 6 day longer flowering period than N. sanderae.

The distributional characteristics about 8 syntaxa of mantle communitly (Mantelgesellschaften) in South Korea was studied. This study was carried out by geographic and bioclimatic analysis on 326 phytosociological releves on the basis of syntaxonomy and hierarchical system of mantle community already obtained from Zurich-Montpellier School's method, which involves direct analysis on the latitude, altitude, annual mean temperature and the lowest temperature of each site. The distributional characteristics of mantle communities in South Korea appeared from South to North in the order of Mallotetum japonicae, Clerodendretum trichotomae, Akebietum quinatae, Lonicero-Puerarietum lobatae, Spiraetum salicifoliae. Dioscoreo-Actinidietum argutae, Sorbarietum stellipilae and Tripterygietum regelii. It is suggested that the information (syntaxonomical, floral, geographic and bioclimatic data) of Japan, North Korea and China is essential to determine the distributional characteristics of mantle community in Korean Peninsula.

인간이 자연의 식물과 교감하는 화예는 역사적인 배경과 민족성에 따라 특징을 가지며 인간의 영감과 조형 능력으로 서로 다른 양상의 문화가 탄생 되었다. 한국의 화예는 사계절기후의 자연 속에서 발생한, 문명의 소산으로 자연합일사상(自然合一思想)에서 출발하여 우리민족의 심성에 흐르고 있는 자연주의적 본질의 삶과 철학을 시대의 문화에 맞게 자연식물(草木)로서 그 여유로운 미를 덕(德), 지(志), 기(氣)로 배양되어 빚어내었다. 문인화(文人花)는 역사적 전통인 동양철학의 바탕에 계승되어온 정신 이념이 고격의 인품과 시정성{詩情性)을 바탕으로 "외양(外樣)"보다는 식물이 지닌 특성과 취향을 기교의 표출됨이 없이 철리(哲理)의 미학적 함축성을 빚어낸 조형예술이다 본 연구에서는 우리 정신문화의 화예 근간이 문인화(文人花)임을 규명하기 위하여 소나무(松)를 중심으로 문인화의 배경과 근원, 시정성, 상징성, 우의성, 그리고 문인화 작품에서 표현되는 화예의 조형성과, 화예 유전자 해독으로 미학적 특성을 파악함과 동시에 문헌의 기록을 도출하여 연대별로 정리 고찰하고, 한국화예의 정수(精髓)인 문인화론을 정립하고자 한다.

Background: Honey from different geographical origins can have distinct characteristics due to variations in the floral sources available to stingless bees in different regions. The most abundant stingless bee for meliponiculture in Thailand is Tetragonula pagdeni. However, only a few studies about the properties of honey from a different origin were carried out. The objective of this study was focused on a comparative study to evaluate the melissopalynological, physicochemical, antioxidant activities, and total phenolic contents (TPCs) of stingless bee honey produced by T. pagdeni from different parts of Thailand. Results: Fifty honey samples were collected from five locations, and the physicochemical properties of T. pagdeni honey samples are acidic (pH 3.02-4.15) and have a high water content (18.42-25.06 %w/w), which is related to the regions of meliponary. Melisopalynological analysis reveals the predominant pollen from Melaleuca quinquenervia, Cocus nuciferca, Nephelium lappaceum, Salacca wallichiana, and multiflora honey. All honey samples were analyzed for their TPC and 2,2-diphenyl1-picrylhydrazyl radical scavenging activity. The results show that all samples had high TPC and antioxidant activities with a strong correlation (p < 0.05). Conclusions: The data from this study indicates the importance of geographical origin, which links physicochemical properties, phenolic compounds, and functional characteristics to their floral. Besides, the floral sources and harvesting location affected the properties of stingless bee honey. Our results identify Melaleuca honey as a promising source of phenolic content and antioxidant activity that can be used as a functional food, as well as multiflora and Cocus honey. However, further studies are required to characterize the phenolic compound and its biological potential, which could be a stingless bee honey biomarker and quality control, simultaneously with the physicochemical analysis.

NTR1 gene of Brassica campestris L. ssp. perkinensis encodes a floral nectary-specific methyltransferase. In this study, the NTR1 cDNA was expressed in E. coli to examine the enzymatic characteristics of the protein product. The GST-NTR1 fusion protein was purified to near homogeneity, showing that the size of NTR1 was 44 kDa. The protein reacted specifically with jasmonic acid (JA), consuming methyl group from S-adenosyl-L-methionine (SAM). GC-MS analysis revealed that the compound produced was authentic methyl jasmonate (MeJA), suggesting that NTR1 is an S-adenosyl-L-methionine: jasmonic acid carboxyl methyltransferase. Km values of NTR1 for JA and SAM were 38.0 and $6.4{\mu}M$, respectively. Optimal activity of the NTR1 was observed at $20^{\circ}C$, pH 7.5, in the presence of 100-150 mM KCl. Thus, kinetic properties, thermal characteristics, optimal pH, and ion-dependency of the NTR1 activity were almost identical to those of Arabidopsis JA methyltransferase JMT, indicating that these two proteins are orthologues of each other.
