박호용 한국몽골학회 2015 몽골학 Vol.0 No.43
This paper attempts to examine policy measures for reviving stagnant economy of Mongolia. Mongolian economy has been recently in a difficult situation because of downward trend in prices of minerals and presumably faced with an ordeal of protectionism. The Bank of Mongolia says mineral exports accounted for 90 percent of the country's economic growth, and recent stagnant of Mongolia has been most attributed to the downward trend in prices of minerals. According to the 12th GTA reports, G8 nations are being hit frequently by beggar-thy-neighbour policies, while small countries such as, Mongol and Korea are being harmed by protectionist measures more frequently than any other countries. The consequences shows that GDIs of China and Mongolia are recorded as lower than GDP because of negative gains of trade since 2005. This infers that the current loss of trade will be followed by a period of protection measures. We propose that we should basically prepare liberalizing measures, because Mongolia has been aimed at an open-economy export-oriented since the era of economic transition. On the other hand, we selectively prepare protecting measures because Mongolia is no longer small country in a point of view, such as mineral industry. Specific policy measures mentioned above are discussed.

흰점박이꽃무지(Protaetia brevitarsis)의 유충 체강에 적당량의 E. coli 현탄액을 주사하고 일정시간 경과후의 체액을 채취하여 유도된 항생활성물질 탐색 및 활성범위를 검정하였다. 탐색된 물질을 plate growth inhibition 방법으로 항생활성을 측정하고 이온교환 크로마토그라피, 역상 HPLC, 이온교환 HPLC 및 SDS-PAGE 등의 방법에 의해, 분자량 약 9 kDa, 12 kDa의 항생활성 펩타이드를 분리정제하고 이들을 각각 프로테신(Protaecin) I과 II로 명명하였다. 프로테신 I은 광범위의 그람 양성세균 및 그람 음성세균에 대하여 강한 항생활성을 나타내었으며, 프로테신 II는 일부 그람 양성세균에 특이적으로 높은 항생활성을 나타내었다. 또한 프로테신 I과 II는 pH와 열에 대해서도 안정하였다. The induced antibiotic peptides were isolated from the white-spotted flower chafer, Protaetia brevitarsis by injection of E. coli suspension to the larvae of the insect. The antibacterial activity of the peptides were assayed by the plate growth inhibition method, and were purified by ion-exchange chromatography, reversed-phase HPLC, ion-exchange HPLC and SDS-PAGE etc. The peptides were estimated as 9 kDa, 12 kDa in molecular weight and named Protaecin I and Protaecin II, respectively. Protaecin I and II have strong antibacterial activities against Gram-positive and/or Gram-negative bacteria, and they are stable in the heat treatment and in the range of pH 2-12.
