Electric and Magnetic Field caused by transmission line are limited to prevent giving human body any effect by related standards. However, when road, building and bridge are newly built near the transmission line, electric and magnetic field over the standards are generated. In this study, highway noise barrier was applied to reduce electric field of a road installed near the transmission line. To select the most appropriate model of the barrier, we corrected errors between measurement and simulation results and simulated several structures of barrier.

The objectives were to compare the salt tolerance levels in the parental rice cultivar, Dongjinbyeo, and induced mutagenesis derived its lines for plant height, MDA, ATPase, POD, and 2-dimensional protein electrophoresis pattern in NaCl-containing hydroponic nutrient solutions. Rice plants isolated from a population of rice (Oryza sativa L. cv. Dongjinbyeo) mutation lines, which were generated in combination with in vitro selection and gamma-ray, exhibited salt tolerance. Line No. 18 had the longest plant, whereas NaCl-sensitive line (No. 25) had the shortest plant. The parent, and the sensitive line showed severe damage from salt stress. Tolerant lines (No. 18, 50) had a lower malonaldehyde (MDA) content than the sensitive one (Dongjinbyeo, No. 25) during salt stress. Several proteins showed significant quantitative variation through 2DE; phosphoribulokinase, peroxidase, oxygen evolving enhancer 1 and the $H^+-ATPase$, which are known to be involved in salt tolerance. The effect of salt on peroxidase and $H^+-ATPase$ activity in the seedlings of two groups with contrasting genotypes of rice was studied. A greater activity was recorded in the tolerant lines as compared to the sensitive ones (P<0.05, Duncan's test). The results indicate that salt tolerant lines expressed more salt stress-inducible proteins associated with salt tolerance than the sensitive lines during salt stress.

후복강 종양은 비교적 드문 질환이며, 대부분 증상 발현이 없다가 전산화 단층 촬영 등을 통해 우연히 발견되는 경우가 많다. 저자들은 우연히 발견된 후복강 종괴를 주소로 내원하여 외과적 절제술 후 매우 희귀한 질환인 기관지원성 낭종을 병리조직학적으로 진단하였기에 최근 5년간 본원에서 진단받은 연부조직 후복강 종양들의 비교 및 문헌고찰과 함께 이를 보고 하는 바이다. Retroperitoneal tumors are rare. They are asymptomatic, and are often found incidentally on abdominal computed tomograms (CTs). The patient reported here visited our hospital complaining of right flank pain. On abdominal CTs, a left-side retroperitoneal mass and a right ureteral stone were found. The hormonal study was normal. After surgical excision, the tumor was confirmed to be a bronchogenic cyst histologically, a very rare cause of retroperitoneal tumor. Our medical center has seen 15 cases with a soft tissue mass in retroperitoneal space over the past 5 years. Benign tumors were incidentally, while malignant tumors were often diagnosed after the patient complained of a palpable mass. In many of these cases, the radiologic impressions and pathologic diagnosis were inconsistent.(Korean J Med 71:97-102, 2006)

BACKGROUND: Human adipose tissue is routinely discarded as medical waste. However, this tissue may have valuable clinical applications since methods have been devised to effectively isolate adipose-derived extracellular matrix (ECM), growth factors (GFs), and stem cells. In this review, we analyze the literature that devised these methods and then suggest an optimal method based on their characterization results. METHODS: Methods that we analyze in this article include: extraction of adipose tissue, decellularization, confirmation of decellularization, identification of residual active ingredients (ECM, GFs, and cells), removal of immunogens, and comparing structural/physiological/biochemical characteristics of active ingredients. RESULTS: Human adipose ECMs are composed of collagen type I–VII, laminin, fibronectin, elastin, and glycosaminoglycan (GAG). GFs immobilized in GAG include basic fibroblast growth factor (bFGF), transforming growth factor beta 1(TGF-b1), insulin like growth factor 1 (IGF-1), vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), BMP4 (bone morphogenetic protein 4), nerve growth factor (NGF), hepatocyte growth factor (HGF), and epithermal growth factor (EGF). Stem cells in the stromal-vascular fraction display mesenchymal markers, self-renewal gene expression, and multi-differentiation potential. CONCLUSION: Depending on the preparation method, the volume, biological activity, and physical properties of ECM, GFs, and adipose tissue-derived cells can vary. Thus, the optimal preparation method is dependent on the intended application of the adipose tissue-derived products.

In this work, experimental investigation is carried out in order to design and fabricate the UHF sensor that is able to detect the partial discharges produced from 10 artificial defects introduced into the real scale 70kV GIS mock-up under high voltage within a well shielded room. As well, in order to verify the on-site applicability of our method, the newly proposed CAPD (chaos analysis of partial discharge) is combined with spectral analysis for identifying the nature of 10 artificial defects under investigation. The PD pattern recognition of each defect has been fulfilled by applying our ANN software. The result indicates that the recognition rate reaches up to 80% by the newly proposed method while the traditional PRPD analysis method allows us to obtain 41%. In consequence, it can be pointed out that the proposed method seems likely to be applicable to the real GIS at the site.
