OSP(Organic Solderability Preservatives)표면처리는 저비용, 고신뢰성, 친환경 특성으로 기존의 금속계 표면처리인 Ni/Au 표면처리를 대체할 수 있는 공정으로 관심 받고 있다. 그러나, OSP는 저분자로 구성된 유기물이므로 여러 온도공정으로 구성된 전자패키지공정에서 제품의 변색이 필연적으로 발생하여 전체 양산수율에 미치는 영향은 매우 크다. 본 연구에서 OSP 처리된 제품을 전자패키지 공정별로 발생하는 변색수준에 따라서 시편을 분류 및 채취하여 변색원인분석 및 솔더조인트 특성평가를 수행하였으며, 기존의... -

Due to their similarities with humans in anatomy, physiology, and genetics miniature pigs are becoming an attractive model for biomedical research. We aim to establish and evaluate blood type O cells derived from Korean native pig (KNP), a typical miniature pig breed in Korea. Ten cell lines derived from 8 KNP piglets and one adult female KNP (kidney and ear tissues) were established. To confirm the presence of blood type O, genomic DNA, fucosyltransferase (FUT) expression, and... -

Coactosin-like protein 1 (Cotl1), a member of the actin-depolymerizing factor (ADF)/cofilin family, was first purified from a soluble fraction of Dictyostelium discoideum cells. Neuronal migration requires cytoskeletal remodeling and actin regulation. Although Cotl1 strongly binds to F-actin, the role of Cotl1 in neuronal migration remains undescribed. In this study, we revealed that Cotl1 overexpression impaired migrationof both early- and late-born neurons during mouse corticogenesis.... -

Korean red ginseng (KRG) has long been used in traditional Korean and Oriental medicine. However, the anti-bacterial mechanism and therapeutic efficiency of KGR for intracellular Brucella infection are still unclear. In this study, the bactericidal activity of Korean red ginseng acidic polysaccharide (RGAP) on Brucella (B.) abortus and its cytotoxic effects on RAW 264.7 cells were evaluated. In addition, B. abortus internalization and intracellular replication in macrophages were investigated... -

The glycoprotein 3 (GP3) of type II porcine reproductive and respiratory syndrome virus has the characteristic domains of a membrane protein. However, this protein has been reported to be retained in the endoplasmic reticulum (ER) rather than transported to the plasma membrane of the cell. In this study, we performed confocal laser scanning microscopy analysis of variants of GP3 and foundthat the signal sequence of the GP3 led to confinement of GP3 in the ER, while the functional ortransmembrane... -

Biocompatible silica-overcoated magnetic nanoparticles containing an organic fluorescence dye, rhodamine B isothiocyanate (RITC), within a silica shell [50 nm size, MNP@SiO2(RITC)s] were synthesized. For future application of the MNP@SiO2(RITC)s into diverse areas of research such as drug or gene delivery, bioimaging, and biosensors, detailed information of the cellular uptake process of the nanoparticles is essential. Thus, this study was performed to elucidate the precise mechanism by which... -

The anionic alkali mineral complex solution, Barodon (Barodon-S.F. Corp., Korea), was evaluated for its effectiveness as a nonspecific immunostimulator in pigs. The effects of Barodon were determined by analysis of feed efficiency, growth rate, and phenotype of leukocyte subpopulations using monoclonal antibodies specific to porcine leukocyte differentiation antigens and flow cytometry (FC). The study was focused to investigate the change in proportion of the CD4+CD8+ double positive T... -

the same concentrations. The peak effect was seen at 72 h in response to 102 nM pimecrolimus. Results of the wound scratch assay and Transwell assays indicate that pimecrolimus is effective in facilitating melanocyte migration on a collagen IV-coated surface. In addition, MITF protein yield reached the highest by pimecrolimus at 102 nM. In brief, pimecrolimus enhances melanin synthesis as well as promotes migration of melanocytes directly, possibly via their effects on MITF protein expression. -

We previously reported that glial cell line-derived neurotropic factor (GDNF) receptor Ձ1 (GFRՁ1) is a direct target of apurinic/apyrimidinic endonuclease 1 (Ape1/Ref-1). In the present study, we further analyzed the physiological roles of Ape1/Ref-1-induced GFRՁ1 expression in Neuro2a mouse neuroblastoma cells. Ape1/Ref-1 expression caused the clustering of GFRՁ1 immunoreactivity in lipid rafts in response to GDNF. We also found that Ret, a downstream target of... -

한국식물병리학회 The Plant Pathology Journal 2013, 29권 1호 10 87-92 (6 pages)
This study was conducted to determine the Phytophthora rot resistance of 514 accessions of watermelon germplasm, Citrullus lanatus var lanatus. About 46% of the 514 accessions tested were collections from Uzbekistan, Turkey, China, U.S.A., and Ukraine. Phytophthora capsici was inoculated to 45-day-old watermelon seedlings by drenching with 5 ml of sporangial suspension (106 sporangia/ml). At 7 days after inoculation, 21 accessions showed no disease symptoms while 291 accessions of susceptible... -

한국식물병리학회 The Plant Pathology Journal 2012, 28권 2호 6 172-184 (13 pages)
An infection risk model for Phytophthora blight on chili pepper was developed to estimate the first date of disease occurrence in the field. The model consisted of three parts including estimation of zoosporangium formation, soil water content, and amount of active inoculum in soil. Daily weather data on air temperature, relative humidity and rainfall, and the soil texture data of local areas were used to estimate infection risk level that was quantified as the accumulated amount of active... -

탄소는 상온부근에서 화화적으로 안정된 원소로 기계 및 화학공업 분야에서 용도가 다양하다. 물리적인 특성으로 탄소는 금속적 성질과 세라믹 성질을 동시에 지니고 있으며, 흑연 결정 성장 정도에 따라 분류되고 그 성장속도가 클수록 금속적 성질을 지니게 된다. 이와같이 어느 쪽의 성질이 지배적인가에 의해 물리적 성질이 다양하며 용도도 달라진다. -

교정치료시 치아이동은 치주인대세포를 매개로 골조직의 개조가 일어나는 과정으로서 골조직의 성장과 개조는 조골세포, 파골세포 및 그 전구헤포의 증식, 분화 및 활성에 영향을 미치는 여러가지 전신적 인자와 국소적 인자에 의하여 조절되고 있다. 1,25-Dihydroxyvitamin D3의 대사물로서 경조직에 있어서 칼슘과 인산의 이동에 중요한 역할을 담당하고 있는 것으로 알려져 있으나 치주인대에 대한 1,25-Dihydroxyvitamin D3의 생물학적 기능은 잘 알려져 있지 않다. 1,25-Dihydroxyvitamin D3가 치주인대세초의 활성에 미치는 영향을...
