  • The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed the contents of standards in the 7th and 2007 and 2009 revised high school biology curricula and compared the contents, amount and the presentation styles of bioinformatics with those of biotechnology in biology textbooks. In result, first of all, there are some vague expressions about biotechnology and bioinformatics in the 7th and 2007 revised curriculum. There is a clear expression about biotechnology in 'life science I' and 'advanced biology' of 2009 revised curriculum. Second, more biotechnology is introduced than bioinformatics in 'science', 'biology I', 'biology II', 'life science I' textbooks. Third, in 'biology for high class' textbook, amount of biotechnology contents in the 2007 revised curriculum didn't increase. An more effort to introduce bioinformatics to science high school student is needed according to revising curricula.

  • 홍합, 따개비 등의 접착성 해양생물은 선박의 하부나 발전소 해수 공급용 튜브에 부착하여 운영 효율을 저하 시키고, 냉각기기 고장을 유발하는 파울링(Fouling) 문제를 야기시킨다. 일반적으로 이러한 문제에 대응하기 위해서 초접착성 해양생물이 주로 부착하는 부위에 $Cu_2O$, ZnO 등을 포함한 유기화합물로 표면처리를 하여 부착방지를 하고 있지만, 이 소재들을 장시간 사용 시 해양 오염 및 부식을 가속화하는 문제를 초례하기 때문에 최근에는 사용을 금지하고 있다. 이러한 유해성 소재 문제를 해결하고자 친환경적이고 부작용이 없는 초접착성 해양생물 부착방지 소재를 개발하고자 하였다. 본 연구에서는 낮은 표면장력을 갖는 PDMS(Polydimethylsiloxane) 소재를 기반으로 소수성 oil을 침투시킨 I-PDMS(Oil-Polydimethylsiloxane) 표면처리법을 고안하였고, 이 방법을 활용하여 초접착성 해양생물에 대한 부착방지 성능을 향상시키고자 하였다. 기존의 개발품들 보다 성능이 향상된 I-PDMS 제조하고자, Nano-indentation을 이용한 기계적 특성 평가, X컷 및 cross-cut을 이용한 부착력 평가, 실제 바다환경에서 해양생물의 부착력 시험, 바다 환경을 모사한 수조에서의 I-PDMS와 비교군 기판에서의 홍합 거동, 홍합과 기판의 접착강도 시험, 해양 미생물 평가를 실시하였으며, 이를 통해서 I-PDMS 성능 및 내구성을 입증하고자 하였다.

  • The genus Ippa Walker, 1864 is reported for the first time from Korea, with a species I. conspersa (Matsumura, 1931). I. conspersa is generally known as myrmecophiles having ecological relationships with some ant species such as Lasius spp. Photographs of adults, immature stages, and the genitalia of I. conspersa are provided.

  • Six monoclonal antibodies to human cardiac troponin I (hcTnI) were produced to eventually develop an immunosensor for acute myocardial infarction (AMI). For the characterization of these antibodies, a set of 11 different peptides covering selected ranges of the complete amino acid sequence of hcTnI was prepared and used for epitope mapping. Such analysis allowed to select an appropriate pair of antibodies that can form a sandwich type of immune complexes and was consequently used for an immunoassay.

  • Annexin I is a member of the annexin family of calcium dependent phospholipid binding proteins and has anti-inflammatory activity by inhibiting phospholipase A$_2$ (PLA$_2$). Recent X-ray crystallographic study of annexin I identified six Ca$\^$2+/ binding sites, which was different types (type II, III) from the well-known EF-hand motif (type I). (omitted)

  • The 2D/E gel analysis for polypeptide expression reflecting I-18 C gene (early-ecdysterone inducible gene) has conducted the emerged C. riparius adults from larval phase exposure to tebufenozide acting as an ecdysteroidal molting hormone. Control group, the amount of ORE II of the I-18 C gene was larger than that of ORE I of this gene. After treatments, ORE I of the I-18 C gene was overexpressed as the polypeptide, whereas ORF II of this gene was expressed as the polypeptide and was clearly reduced expression. Accordingly, we consider that tebufenozide exhibited endocrine disruptions related processing of ecdysteroid receptor protein reflecting ORF II of I-18 C gene. Also, earlier emergence day was related overexpressed polypeptide reflecting ORE I of I-18 C gene. In this study result, tebufenozide induced changing of physiological condition, and then polypeptide expression reflecting early-ecdysterone inducible I-18 C gene was different between control group and exposure group.
