Promoter prediction is a very important problem and is closely related to the main problems of bioinformatics such as the construction of gene regulatory networks and gene function annotation. In this context, we developed an integrated promoter prediction program using hybrid methods, PromoterWizard, which can be employed to detect the core promoter region and the transcription start site (TSS) in vertebrate genomic DNA sequences, an issue of obvious importance for genome annotation efforts. PromoterWizard consists of three main modules and two auxiliary modules. The three main modules include CDRM (Composite Dependency Reflecting Model) module, SVM (Support Vector Machine) module, and ICM (Interpolated Context Model) module. The two auxiliary modules are CpG Island Detector and GCPlot that may contribute to improving the predictive accuracy of the three main modules and facilitating human curator to decide on the final annotation.

We describe a newly recorded brittle star to South Korea, Amphiura (Amphiura) digitula (H.L. Clark, 1911), that was collected from Geoje Island, at a depth of 47 m. The species is characterized by a small disk, covered by numerous fine scales, small radial shields that are wider than long, a small stumpy hook at the distal end of the radial shield, two tooth papilla, two adoral shield spines, 2nd adoral shield spine longer than other, tapered dramatically toward dull tip, five arms with four proximal arm spines, and two tentacle scales. We also obtained a 657 bp sequence from COI gene and the amplified sequence matched the general DNA barcoding region. The NJ and ML phylogenetic analyses revealed A. (A.) digitula as monophyletic in the Amphiura clade. This species is clearly distinguished from other Amphiura species by morphological characteristics and the mitochondrial COI sequence, and thus represents the sixth Amphiura species reported to occur in Korea.

Present author observed the variation in color and pattern and also those of geographical distribution of Graphosoma rubrolineatum WESTWOOD.And the variations were also studied in relation to the temperature and the humidity . The results are as follows . 1. The variations in color and pattern of G.rubrolineatum were gradually changed into black ones, and so they showed polymorphic. 2. Their colors and patterns were not variated in inland at all, while those variations in island increased according to the distance from the inland. 3. The red color of the patterns appeared the yellowish-red in inland, the blackish -red in island. 4. The variation in color and pattern of G.rubrolineatum occure in the region of the temperature below 22.8$^{\circ}C$ (mean temperaturrre of June, July and August)and the humidity above 72%(yearly average).

In order to use sea breezes to counter the heat island phenomena, i.e. to promote urban ventilation, it is necessary to clarify the effect of building morphology and height on large-scale wind fields. In this study, the sea breeze in the vicinity of the Kanto Plain in Japan is simulated using a mesoscale meteorological model incorporating an urban canopy model, and the inland penetration of sea breezes is accurately reproduced. Additionally, a mean kinetic energy balance within a domain (Control Volume; CV) moving along the sea breeze is analysed. From the results, it is clarified that the sea breeze is interrupted by the resistance and turbulence caused by buildings at the centre of Tokyo. The interruption effect is increased in accordance with the height of these buildings. On the other hand, adverse pressure gradients interrupt in the internal region.

Lichen genus Sarcographa Fee, a stromatoid Graphidacean taxa, was newly found in Geomun Island, Jeonnam province. The lichen grew on the bark of Camellia japonica and Eurya emarginata along the coastal line of the island. It was identified as Sarcographa tricosa (Ach.) Mull. Arg. for the first time in Korea.

곶자왈 숲이란 대한민국 제주도에 있는 "아아 용암"이라는 바위 지대 위에 형성된 숲을 가리킨다. 이 논문에서 곶자왈 숲이 람사협약상 국제적으로 중요한 습지임이 밝혀진다. 곶자왈 숲은 람사협약에서 습지의 한 종류로 규정하고 있는 지하수시스템이므로 람사협약상 습지로 간주되어야 한다. 또한 곶자왈 숲은 수문학적 중요성을 가지고 있는 제주도의 대표적인 습지유형이며 희귀식물들의 자생지이므로 국제적으로 중요한 습지이다.

This study focuses on monitoring the surface UHI in a tropical city of Bangkok in both spatial and temporal dimensions based on MODIS- and TM -derived land surface temperature (LST). The spatial extension and magnitude of the surface UHI are explored for days and nights as well as its variations through the dry (least-clouded) season. Surface UHI growth between 1993 and 2002 is mapped using highresolution LANDSAT TM thermal bands. UHI patterns are, then, analyzed in association with land/vegetation covers derived from high-resolution ETM+ and ASTER satellites and ancillary data.

The basalt fiber, which is found to be non-toxic and harmless to the human body, is expected to become a trend for industrial fibers as they have better properties of non-combustion, heat-resistant, soundproof, absorbent, moistureproof, wear-resistant, corrosion resistant, lightweight, and high strength properties. Thus, in this study, we analyzed the chemical compositions of basalt produced at seven sites on Jeju Island for making a high value inorganic insulation material. The results showed that the MgO content of basalt collected from the eastern part of Jeju Island was higher than 7.5 percent, while that of the western region was less than 6 percent.

본 연구는 제주도의 전체 지하수공 중 수역별로 대표성이 있는 150공을 선정하여 고도에 따른 수질 특성을 파악하는데 목적을 두었다. 수질특성의 평가는 물리.화학적 특성과 통계분석을 이용하였다. Piper diagram에 의한 수질 유형은 표고 50m이하 지역은 $Na^{+}$＋ $K^{+}$-C $l^{-}$ 형태를 보이고 있다. 40~100 m에 위치한 지하수에서는 $Na^{+}$＋ $K^{+}$-HC $O_3$$^{-}$ ＋C $O_3$$^{2-}$ 형태와 일부 $Na^{+}$＋ $K^{+}$-C $l^{-}$ 형태의 군을 이루고 있다. 그리고 100 m이상의 지역에서는 $Na^{+}$＋ $K^{+}$-HC $O_3$$^{-}$ ＋C $O_3$$^{2-}$ 형태에 속하고 있다. 요인분석 결과, 50 m이하와 100 m이상 지역에서 공통적으로 TDS와 오염물질 2개 요인이 추출되었다. 50~100m지역에는 3개의 요인이 추출되었으며, 요인1에는 TDS함량으로 요인2는 오염의 영향과 광물용해로 볼 수가 있다. 그리고 요인 3에는 HC $O_3$$^{-}$ 함량으로 나타났다..

DNA extracted from ancient bones of Cervidae animals was examined to identify the species and to determine the phylogenetic relationships to those from extant cervids. Abundant ancient bones were excavated from Kumsung archaeological site in Jeju Island, Korea, and were identified as Cervidae animals based on morphological features of their antlers and lower mandibles. Their mitochondrial DNA (mtDNA) control region (CR) was partially sequenced and subsequently compared with those previously reported in database. The results confirmed that the ancient sequences are lineage of Cervidae. On the phylogenetic trees constructed using the sequence diversity of the CR sequences of family Cervidae, the ancient DNA sequences were found on distinct clusters. The ancient sequences were located in the subfamily Capreolinae cluster, and six ancient sequences were closely related to those of extant Korean roe deer in Jeju Island and Korean Peninsula. Consequently, the results of this study suggest that the roe deer inhabited Jeju Island in ancient times. However, there is no evidence for the existence of subfamily Cervinae, including Sika deer, while it has been described in several historical records. The results suggest that this finding could contribute to understanding of the origin and phylogenetic relationships of extant and ancient roe deer on Jeju Island.
