  • An electron microscopical study on hemocytes of last instar larvae of Orthoptera (Acrida cinerea Thunberg, Paratenodera sinensis De Saussure, Atractomorpha lata Hotschulsk was performed to observe cell types, structures and their origins. Prohemocytes are the smallest round cells with large, nucleus, poorly developed cytoplasmic organelles and lower composition ratio, accouting for less than 1% of all cell types. Little remarked differences were revealed among different species. Plasmatocytes are relatively large cells with higher composition ratio, accounting for 5 to 20%. The majority of the plasmatocytes are oval forms with numerous external cytophismic projections., relatively well developed cytoplasmic organelles. Granular cells are characterized by various granules in cytoplasm. Some considerable remarked differences were revealed among different species. Furthermore the granules themselves differ in fine structures. Adipohemocytes were found only in Acrida cinerea Thunberg.

  • Proton lineshapes and chemical shifts of paramagnetic solutions of Ln$(NO_3)_3$ in DMF have been measured over the temperature range 240K to 3807K. Solvation sphere exchange rates and the thermodynamic exchange parameters for CHO group of the DMF molecules have been extracted from these data. The results were established through a detailed analysis and discussion of the temperature depending data of the 1/$T_2$ and ${\Dellta}{\omega}$ data were analyzed in detail, and it has been found that delocalization of the unpaired electron spin from some $Ln^{3+}$ ion to DMF molecules beyond the first solvation shell would occur, giving rise to a scalar relaxation contribution in the bulk solvent.

  • Based on our insect collecting trip to the Is. Jin-do, Jeollanam-do Province from June 29 to July 1, 2005, a total of 573 lepidopterous species belonging to 37 families are reported, with adding 122 species new to the locality During our survey, the most dominant species was Cryptolechia malacobyrsa Meyrick (Oecophoridae), followed by Sandrabatis crassiella Ragonot (Pyralidae) and Yponomeuta tokyonellus Matsumura(Yponomeutidae), and the family Noctuidae (165 spp.) was the most diverse taxon in species number. We here also discuss the species representing the climatic feature in the island and compare the species diversity with those of other two major islands in Korea, Is. Geoje-do and Is. Jeju-do. Among the species recognized in this study, two species, Epilepia dentata (Matsumura and Shibata) and Meganola costalis (Staudinger) are recorded in Korea for the first time, in spite of the presence of previous notes on the species which is invalid. The adults and genitalia of the two species are illustrated and described briefly.

  • Heating energy was measured in an apartment housing unit with a district heating system, varying the kind of hot water distributors. Ondol coils passing through a living room raised the temperature of the room where the heating was turned off. Including this characteristic of Ondol heating into the modeling, we performed simulations and showed a verification by comparison with the results of measurements. As a result, a main flow control method, which changes hot water flow rate supplied to a housing unit according to the thermal load, can reduce the supplied flow rate and lower the return temperature, compared with a constant flow method. That can result in decreased heat loss in utility-pipe conduits even though the heating energy supplied is almost the same. An outdoor reset control that raises the temperature of the supplied hot water if the outdoor temperature falls has the effect of a quicker response in heating than the reduced flow rate and return temperature.

  • The study of insect fauna in Taeanhaean National Park in Korea began with the first survey of natural resources in 1996, and then the surveys were conducted seasonally from 2005 to 2014. The surveyed sites were mostly coastal areas, sand dunes, and back grasslands. Insects were collected by sweeping with insect net, suction, pitfall trap, light trap, and Malaise trap. As a result, a total of 1,540 species of 215 families belonging to 17 orders were identified. Lepidoptera was the most populous group at 34.2% and followed by Coleoptera at 28.3%, Hemiptera at 12.7%, Diptera at 8.5%, Hymenoptera at 7.1%, Orthoptera at 4.7%, Odonata at 2.0%, and others. The analysis of change of arenaceous insect fauna before and after the accident by the Hebei Spirit that spilt oil in Taean in December 2007 showed that 45 arenaceous insect species, mostly belonging to Coleoptera, were observed through the whole survey period. The impact of oil spill on the number of arenaceous insect species appearing in the area was minor.

  • This research is insect diversity analysis on the basis of survey results and bibliographies of Hongdo Island, Mts. Seoraksan, Hallasan, Daeamsan & Daeusan, Hyangnobong peak & Geonbongsan nature reserves and Dokdo Protected Natural Area among 10 designated nature reserves. The Mt. Hallasan nature reserve has 1,867 species in 22 orders and shows the highest species diversity. The species diversities of Mt. Seoraksan, Mt. Hyangnobong peak & Geonbongsan, Hongdo Island, Mt. Daeamsan & Daeusan, and Dokdo Protected Natural Area reveal 1,604 species in 19 orders, 704 species in 18 orders, 474 species in 19 orders, 468 species in 16 orders, and 114 species in 11 orders, respectively, in descending order. The order Lepidoptera shows as dominant taxa in Hongdo, Seoraksan, Hallasan, Hyangnobong peak & Geonbongsan, whereas the order Coleoptera as subdominant taxa in these areas. On the other hand, in Mt. Daeamsan & Daeusan, and Dokdo Protected Natural Area, the order Coleoptera appears as dominant taxa whereas the order Lepidoptera as subdominant taxa. The order Ephemeroptera has been shown the highest species diversity in Seoraksan which is reported to 25 species, Odonata in Hallasan to 28, Dermaptera in Seoraksan to 9, Orthoptera in Hallasan to 51, Hemiptera in Hallasan to 175, Homoptera in Seoraksan to 126, Hymenoptera in Hallasan to 183, and Diptera in Hallasan to 206. The species diversity is generally poor in Daeamsan & Daeusan, Hyangnobong peak & Geonbongsan, and Dokdo Protected Natural Area. Maybe this result is caused by the lack of various academic surveys compared to the other areas. It is needed to study systematic academic investigation on insect in the nature reserve areas in Korea, and to plan appropriate management and conservation on natural environment considering biodiversity of each nature reserve area.

  • In recent years, strong typhoons have passed South Korea almost every year and severe damages were incurred directly and indirectly. However, instances where wave and wind data were procured from the offshore approach path of the typhoon are very rare and thus researchers are experiencing difficulties in obtaining calibration and verification data of typhoon-generated wave modeling. This paper provides a synthesis of records of observations by the Korea Meteorological Administration and Korea Institute of Ocean Science and Technology on storm waves generated by the typhoons SONGDA, NABI, and SHANSHAN that passed from 2004 to 2006 in order to help researchers interested in typhoon-generated wave numerical modeling. Although the trajectories of typhoon NABI and SHANSHAN were east of the Korea Strait, a significant wave height of 8.3 m was measured at Namhyeongjedo located east of Geojedo. Moreover, an unprecedented significant wave height of 12.2 m was measured for both typhoons at a station 1.4 km away from Yeongil Bay breakwater. Meanwhile, a comparative analysis of data obtained with a ocean data buoy at Geojedo and a Directional Waverider at Namhyeongjedo showed maximum wave heights that were similar but considerably different significant wave heights.

  • Since based on the revised educational curriculum, the insects and spiders in eight biology textbooks I and II of high school are as follows. In class level, two classes, Insecta and Arachnida were investigated and their frequence numbers in the textbooks were a total of 143 times. In order level, 12 orders in insecta, 2 orders in Aranea were appeared in the textbooks. The most appearing frequence number was represented in Lepidoptera (33 times) and then in Araneae (11 times). For each publisher, the most appearing frequencies of insecta and spiders was shown in Gyohaksa (23 times), and then in Hyeongseol and Centurla education research institute (21times, respectively). In the textbooks, four species were found to misidentify in their species name and five mistakes were investigated in their photos and content.
