This study aimed to establish the best applicable method for the National Ecosystem Survey (NES) guidelines by (i) verifying the efficiency of an insect trap that combined the Malaise trap, flight intercept trap, and pitfall trap (MFP trap) as part of the improvement for the terrestrial insect field in the fifth NES, and (ii) comparing the result with the currently used Malaise trap and pitfall trap (MP traps). We found that the efficiency of attaining species diversity was much higher with the added flight intercept trap function than the current Malaise trap alone for flying insect collection. For collecting ground insects, the efficiency of attaining species diversity of the pitfall trap from the MFP trap was lower than that from the MP trap. Besides, the Malaise trap of the MP trap showed superior efficiency than that of the MFP trap in species diversity. The results suggested that modification, supplementation, and re‐testing should be performed by analyzing various factors such as the trap material, barrier size, capturing container inlet, and mesh size, with consideration of the design of the current Malaise trap. Therefore, in survey‐based research, which aims at identifying insects species diversity and inhabiting status—such as the NES, it is necessary to introduce the MFP trap with the flight intercept trap function added to the Malaise trap function, and for the pitfall trap function of the MFP trap, it can be operated as a separate trap from the MFP trap.

Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces tenuipes Jocheon-1. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. Paecilomyces tenuipes Jocheon-1 cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes Jocheon-1 was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDHis comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The cDNA encoding Pt-GAPDH was expressed as a 37 kDa polypeptide in baculovirus-infected insect Sf9 cells. The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA.

Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues.

Since 1981, Korean enterprise's foreign direct investments have rapidly increased over 100% as compared with previous year. These foreign direct investments were mainly invested in overseas marketing for export promotion or extraction industries for raw material acquisition. The purpose of this study is to guide the Korean enterprise's to recognize country risk which they are confronted in host countries. Analysis of the host country environment before investment will give good opportunity and good profit to investing companies, And country risk assessment will minimize or avoid losses where they are involved or invested. In this study, I tried to analyze factors which compose the environment and economic or non-economic constraints to enterprises in host countries. With these factors, I studied techniques which were developed by enterprises and international banks to assess country risk. Country risk assessment enables to plan counter-strategies against level of country risk to executives or middle managers of enterprises. Therefore, I presented the counter-strategies which enterprises developed for high-risked host countries and how they adopted them in investment decision making. But I only presented the conceptional framework of country risk and introduced foreign enterprises techniques in this paper and could not contribute to Korean enterprises developing unique techniques. I suggested that Korean enterprises, which have no analysis staff and no counter-strategies available eventhough they are already involved and invested in developing countries.

The base stations of CDMA(Code Division Multiple Access) digital system are shared with those of analog AMPS(Advanced Mobile Phone Service) system because of limited space, easy maintenance, and economical reasons. Moreover, the primary channel frequency of the CDMA system is next to the A' frequency band of the analog system. The transmitted signal of the analog system thus can be received in the CDMA system and the received analog signal may be intermodulated with the received digital signal. In a series of efforts for finding the intermodulation source, there have been serious testing and examining on the antenna, connectors, and feed lines of the base station. The main source of the intermodulation was the transmitter antenna of the analog AMPS system. Thus, the specification of the antenna in the AMPS system should be less than -115 dBm in case of the duplex antenna.

주홍구,우희종 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.4

The expression of galectin-3 protein in four different gastric cancer cell lines and lymph node tissues of patients with gastric carcinoma was studied by Western blotting, immundhistochenustry and flow cytometry analysis. Western blot analysis of galectin-3 using anti-galectin-3 , mAb indicated that a 29 kDa protein was expressed in 3 gastric cancer cell lines, AGS, KATO BI , and SNU16, but not in SNU1 which was a non-adherent cell line. Interestingly, SNU16 cells secreted galectin-3 into the culture media. Flow cytometry analysis revealed that NIH3T3, AGS, and KATO III cells expressed the galectin-3 on the cell surface. The level a))' galectin-3 expression was highest in AGS (91.5%), high in KATO M (69.5%), and low in NIH3T3 (55.8%). The gastric cancer cells metastasized into .lymph node tissues were heavily stained whereas normal lymphocytes were not stained. This study suggested that the expression of galectin-3 and the metastasis of gastric cancer cells might be correlated.
