Host plants of Popillia quadriguttata (Fabricius) were investigated in golf courses, Fifteen plant species of 15 genera in 13 families were confirmed as host plants of P. quadriguttata. Thus, total number of host plants of P. quadriguttata was 26 species of 25 genera in 18 families including 11 recorded species in literature. In addition, P. quadriguttata adults fed on 30 plant species of 25 genera in 19 families out of the 69 plant species of 53 genera in 33 families supplied as food in laboratory, P. quadriguttata adults preferred Wistaria floribunda in golf courses but Tilia mandshuric, Platanus orientalis, Diospyros lotus, Punica granatum and Chionanthus retusa in laboratory.

In order to know relationships between green euglenoids and environmental factors, the species composition and density were assessed for 12 months together with environmental variables in the Jeonjucheon urban drainage, Korea. Nitrate was a high of 3.22 mg/1 in June and phosphate concentration was over 0.71 mg/l in the winter. The euglenoids totaled 5 genera and 71 species throughout the year, increasing in the early summer (35 to 42 texa) and decreasing in the winter (below 20 taxa). The number of green euglenoids positively correlated with surface water temperature. the total density of the green euglenoids showed a typical bimodal pattern, being maximal in the winter (5,394 cells/ml in June). The winter peak was a result of active growths of Euglena caudata, E. geniculata and E. viridis, however, each of which positively correlated with the phosphate. The early summer peak was attributed to Euglena deses, Lepocinclis ovum, and Phacus trypanon, each of which positively correlated with the ammonium and nitrate. The complete bimodal spectrum of species number and density of green euglenoids provides a sensitive image in detecting the changes of environmental variables in polluted waters such as Jeonjucheon.

This is the first report of Aprion virescens, belonging to the family Lutjanidae, collected in Korea. The specimen (151.4 mm in standard length) was caught by the gill net in the coastal waters of Jeju Island on 30 October, 2009. This species is characterized by having a deep vertical groove in front of eye, very short pectoral fin almost equal to snout length, and four black spots on dorsal fin. We propose a new Korean name, "Nok-saek-tung-dom-sok" and "Nok-saek-tung-dom" for the genus and species, respectively.

지난 5월 13일 녹색성장위원회는 IT 부문의 녹색화와 IT를 통한 경제 사회 전 분야에 걸친 녹색화를 파급시키는 것을 주된 내용으로 하는 '그린 IT 국가 전략'을 수립 심의하였다. 이번에 수립된 그린 IT 국가전략은 기존에 각 부처별로 산재되어 있던 그린 IT 분야 개별 계획들을 연계하는 동시에, 부처간 협력과 조정을 통해 시너지 효과를 창출할 수 있는 새로운 정책 사업 분야를 적극 발굴하려는 취지 하에 범부처 차원에서 마련되어진 종합계획이다.

In order to use the liquid whole eggs as an ingredients of retorted products, the provention of the green-grey discoloration of retorted liquid whole eggs by the addition of the Na$_2$EDTA was investigated. And palatability change of the retorted liquid whole eggs by the addition of Na$_2$EDTA was also investigated. The results obtained were summarized as follows: 1. More severe green-grey discoloration was occurred when higher cooking temperature and longer cooking time were used. 2. Green-grey discoloration of retorted liquid whole eggs could be prevented by the addition of about 0.015% of Na$_2$EDTA. 3. The palatability of retorted liquid whole eggs was not lowered by the addition of 0.02% of Na$_2$EDTA and green grey discoloration was not developed during the storage time of 22 days at room temperature.

This study was carried out to improve utility value as soybean genetic resources and to obtain basic information for color-soybean breeding. The 146 local color soybean lines collected in Kyongbuk province were investigated major agronomic characteristics. Seed coat-color showed seven different types which were black, white mottled on black, white mottled on brown, black saddle on green, green, raddish brown and brown. Major color types were black and green colors. The 90 percent of collected lines were purple in flower color. The 86 lines were green in color of cotyledonary part and 64 lines yellow. Great variations were observed in days to flowering and days from flowering to maturity, 51 to 81 days and 75 to 103 days, respectively. But days to maturity was 150 to 159 days and had smaller variation than days to flowering and days from flowering to maturity in all lines except those with white mottled on black (123 days). The 100 seed weight ranged below 10g to over 36g. Black seed color with green embryo seed was heavier seed weight than black seed color with yellow embryo seed. Seed shape of all collected lines was ellipsodial and average ratio of length: width: thickness of seed was 1:0.87:0.69. Positive correlation coeffieients were obtained among seed length, width, thickness and 100 seed weight.

Pine (Pinus densiflora) forests of 315 sites were classified by applying the phytosociological method, TWINSPAN and DCA (detrended correspondence analysis). The floristic composition and diversity patterns of the vegetation types analyzed and documented. The vegetation types were classified 8 groups including 4 groups of Quercus mongolica type and 4 groups of Quercus serrata-Smilax china type. Taxonomically, Compositae was the most diverse family (21 genus, 45 species) and followed in order of Liliaceae (18 genus, 34 species), Rosaceae (17 genus, 34 species), and Leguminosae (15 genus, 25 species). The patterns of species richness, diveristy and evenness were significantly different among the vegetation types. In altitudinal pattern of species diversity, species richness monotonically decreased but species evenness increased with increasing altitude.
