  • Korea Aerospace Research Institute (KARI) has a plan to launch COMS for consistent monitoring of the Korean Peninsula. Korea Geostationary Ocean Color Imager (GOCI) is one of the main payloads of COMS which will provide a monitoring of ocean-colour around the Korean Peninsula from geostationary platforms. Ocean color observation from geostationary platform is required to achieve the proper spatial and temporal resolution for coastal observation mission. In this paper the characteristics of GOCI and LEO sensors are discussed. GOCI will provide the measurement data of 6 visible channels and 2 near-infrared channels (400nm ~ 900nm). The integration time and aperture diameter required to achieve the SNR specification of KGOCI are analyzed.

  • In the family Hydroptilidae, Trichoptera, 11 species in 3 genera, Hydroptila Dalman, 1819, Oxyethira Eaton, 1873 and Stactobia McLachlan, 1880, have been recorded from the Korean Peninsula but, until now, no species in the genus Orthotrichia Eaton, 1873. In this paper, we describe a new Korean species, Orthotrichia coreana sp. nov., based on adult specimens from the middle reaches of rivers in the southern region of the peninsula. This species is similar to O. iriomotensis Ito, 2013 from the southernmost region of Japan, but is clearly discriminated from the latter by features of the male and female genitalia.

  • the geoecology of the alpine and subalpine belts of the Korean Peninsula, its component plant group, its environmental history, and climatic amplitudes of the arctic-alpine and alpine plants has reviewed and discussed. The present-day alpine and subalpine landscapes are likely to have been formed during the post-glacial warming phase. The disjunctive distribution of many alpine and subalpine plants, however, suggests a former continuous distribution of these both locally and on a broader, and the subsequent breakdown of a former continuous range into fragments as the climate ameliorated during the post-glacial warming phase. The presences of numerous arctic-alpine and alpine plants on the alpine and subalpine belts of the Korean Peninsula, are mainly their relative degree of sensitivity to high summer temperatures. The continued survivals of alpine species and landscape in Korea is in danger if global warming associated the greenhouse effect takes place.

  • An attempt is made to present a method of prediction for typhoons apporaching the Korean-peninsula. The method is based upon the Bayesian theorem to improve the observed (prior) probabilities of typhoons approaching the Korean sea area incorporating conditional probability. A total of 248 typhoons is collected and analyzed to establish prior probability and conditional probability according to the defined procedure. The typhoons used are those which encompassed the western Pacific area to which the Korean-peninsula is subjected. The results of examplary computations suggest that the presented method is promising for predicting approaching typhoons.

  • In this study, statistical analyses implemented in the EPRI EQHAZARD programs were employed to estimate the sismicity parameters in the Korean peninsula based upon an combined Korean earthquake catalog. The combined earthquake catalog was prepared by performing earthquake clustering analysis on the collected earthquake catalogs provided by experts of the seismic panel during the PSA for Yonggwang Units 1 & 2. The duplicate earthquake events and secondary events in earthquake clusters have been successfully screened. The resultant earthquake catalog was analyzed to quantitatively assess the incompleteness of the earthquake catalog for specified earthquake magnitudes and time periods. The result shows that the earthquake catalog of the Korean peninsula is complete for the times periods of 1392 ~ 1750 and 1905 ~ 1989 (AD) and earthquake magnitude above 4.5. The PSHA methodology of EQHAZARD features the estimation of inhomogeneous a-and b-values within a seismic source. This study shows various results of a-and b-value is well constrained lying between o.6 and 1.0. Also the confidence of estimated a-and b-value for a specifed location was assessed by quantifing the uncertainty of these parameters using bootstrap simulation.

  • The magnitudes of sea surface temperature (SST) anomalies at 13 coastal stations along the Korean peninsula in the summer and winter for the past 29years (1969-1997) are more larger than those in the spring and autumn. The periods of positive SST anomalies (negative SST anomalies) longer than 1$^{\circ}C$ were 75(74.5) months in the eastern coast of Korea, 47.8(51.6) months in the southern coast of Korea and 69.5(69.8) months in the western coast of Korea during the past 348 months (1969-1997). The predominant periods of the low-pass filtered monthly SST anomalies are 3 years or 13 months, even another predominant period is 24 months. The spatial variation of SST anomalies were confined by regional seas of the Korean peninsula, such as the East Sea, the South Sea and the West Sea itself.

  • Four Tertiary basins are distributed on the eastern coast of the southern Korean Peninsula, that is, Bugpyeong, Yeonghae, Pohang and Yangnam basins from north to south. The Yangnam and Pohang basins are the largest ones and have been well studied on their stratigraphies, paleoenvironments and geologic ages, and their tectonic history is representative on the tectogenesis of the Tertiary basins of the southern Korean Peninsula. The geologic events occurred in the Yangnam and Pohang basins from the Early-Middle Eocene through the Middle Miocene suggest that the Yangnam and Pohang basins resulted from the volcanism and rifting caused by the uprising magma, that is, by the diapiric tectogenesis.

  • The genus Entomognathus Dahlbom 1829 is recorded for the first time in the Korean Peninsula, represented by the species Entomognathus brevis (Vander Linden, 1829). This species is trans-Palearctic in distribution ranging from northern Africa, through Europe, eastward to the Far East, and sole representative of the genus in the Far East. Of which occurrence in the Russian Far East, northern China and Japan were well documented, but nothing has been known so far in the Korean Peninsula. In this study, distributional range of E. brevis is expanded to South Korea in the Far East. Taxonomic information of the species and a revised key to genera of the tribe Crabronini occurring in the Korean peninsula are given.
