Today, we realize that modern buildings and post-modern buildings are rely heavily on an insistent use of elementary geometrial shapes. Some, like the square, are easy to draw and others, like the circle and the triangle, or solids based on them like the cylinder, are rather more awkward to manage. Yet the worst contemporary architects and industrial designers will use them. The idea has got about that elementary geometrical shapes are in some way better than more complicated shapes. Generally Speaking, we owe this tendency to Neo-Classical architect. But it goes back much further. The objectives of this report are to analize the process that have been developed since seventeenth century, and this tendency can not equalize with original conception of Platonism.

The composition and the microstructure of the Ag-Cu alloy electrodeposits electroplated in Succinimide bath were investigated varying the electrolysis conditions such as bath composition, current density and additive agents etc. The cathode overpotential increased with the increase of Succinimide concentration and current density ratio in the bath. The Ag content of the alloy deposits decreased with the increase of current density and pH and temperature in the bath. The optimum condition for 78wt.%Ag-22wt.%Cu code position alloy is an follows : pH10(adjusted by NH_4OH), 0.03M AgNO_3, 0.27M Cu(NO_3)_2 3H_2O, 0.5M Succinimide in bath and 3.5A/dm^2∼5.5A/dm^2 current density.

파이프라인 시스템 합성을 위한 스케쥴링

朴道淳,尹薰炳 弘益大學校 科學技術硏究所 1995 科學技術硏究論文集 Vol.6 No.-

Scheduling is an important step which decides designed area and execution time of result hardware. Pipelining is a technique for increasing execution speed and resource utilization of designed hardware in case of executing much successive data. In this paper, we present an pipeline scheduling algorithm which decreases search space in getting through with the optimal solution. This algorithm can be used with other constructive scheduling algorithms. Joining with a constructive algorithm is showed in this paper. This algorithm also can be used to decrease search space in simulated annealing scheduling algorithm.

Background/Aims: Early detection of small primary tumors remains the mainstay of successful cancer therapy and improves survival rates. Matrix metalloproteinases (MMPs) revealed to participate in the early stages of tumorigenesis and primary tumor growth. The aim of the current study was to develop an efficient animal model for early and small colon tumors and assess the feusibility of protease activatable probes to detect early and small tumors. Methods: We used a mouse model for colon tumor by a combined treatment with azoxymethane (AOM) and dextran sodium sulfate (DSS). Male BALB/c mice (n=8, age 5 weeks) were given a single intraperitoneal administration (10 mg/kg body weight) of a colon carcinogen, AOM, followed by 2% DSS in drinking water for 7 days, and there-after they received no further treatment for up to 14 weeks. At week 16, all mice were injected via tail vein with MMP reporter probe (MMPSenseTM680, VisEn, Medical, Inc., MA, USA) followed by surgical exposure of the colon. Excised colons were evaluated with fluorescence imaging, histologic examination, and immunohistochemistry. Results: All mice treated with AOM and DSS developed colon tumors in distal colon with a multiplicity (no. of tumors/mouse) of 7.9±2.1. Fluorescence imaging demonstrated that all tumors were visible with the protease activatable probe. A target-to-background ratio (TBR) of 5.61 for tumor to adjacent normal mucosa was achieved. Histopathologically, all colon tumors revealed adenocarcinoma with or without adenoma. Results of immunohistochermistry confirmed MMP overexpression in the tumor compared with adjacent mucosa. Conclusions: The current experimental study shows that the expression of MMP is up-regulated in the mouse colon tumors induced by AOM and DSS, and highly matched with fluorescence imaging by a protease activatable probe. This strategy can be used to detect early stage tumors and may be used for early diagnosis of early and small tumors.

Oviposition Preference and Development of Adzuki Bean Weevil on Different Leguminous Seeds

Soon-Do Bae,Bishwo P Mainali,Hyun-Ju Kim,Yoon-Young Nam,In-Seok Oh 한국응용곤충학회 2014 한국응용곤충학회 학술대회논문집 Vol.2014 No.04

This study was conducted to determine the oviposition preference and development of adzuki bean weevil, Callosobruchus chinensis (L.) (Coleoptera: Bruchidae) on five different leguminous seeds a) cowpea, b) white kidney bean c) soybean cultivar Daepung d) mung bean and e) azuki bean. A multiple choice test and a nochoice test were conducted to record the number of eggs laid, total developmental time, number of adults emerged, and adult longevity of C. chinensis on the five different leguminous seeds. Both choice and no-choice tests revealed cowpea seed as the most preferred oviposition substrate. Total developmental time from egg to adult stage ranged from 28 to 31 days; shortest of that on the cowpea followed by adzuki and mung bean seeds. Successful development of C. chinensis was not witnessed on soybean or on kidney bean. Rate of adult emergence was higher on adzuki and mung bean seeds with longer adult longevity of those emerged from adzuki bean and cowpea. Higher egg laying preference and shorter developmental time with longer adult longevity of the beetle on cowpea probably signifies importance of physical as well as chemical attributes of the seed as an oviposition substrate other than evolutionary history of the insect. Cowpea seeds can possibly be used as a pull stimulus either as a trap crop or as a stimulant in the mechanical traps against C. chinensis where other leguminous host crops are grown as main crops.

Ceramics TiO2 nanocomposites were prepared by using titanium oxide (TiO2) nanoparticles, fly ash from the thermal powerplant and the mixed waste glass powder. We applied a mechanical milling method and thermal reaction in this process. Thephotocatalytic activities were estimated for methyl orange (MO), acetaldehyde (ATA), 2,4-dichlorophenoxyacetic acid (2,4-D),and methylene blue (MB) as photodegradation targets. Crystallinity, morphological properties, and chemical compositions forprepared ceramics TiO2 nanocomposites were also observed by X-ray diffraction (XRD), field emission-scanning electronmicroscopy (FE-SEM), and energy dispersive X-ray spectrometer (EDS). In addition, density, compressive strength, bendingstrength and chemical durability were measured to characterize the physicochemical properties of TiO2 nanoparticle contents (0-20 wt%). It was verified that addition of TiO2 nanoparticles considerably improves the physicochemical properties of theprepared nanocomposites samples. With increased TiO2 nanoparticle content, the photocatalytic activities of the ceramics TiO2nanocomposites for photodegradation target materials increased under UV light irradiation. The degree of photocatalyticdegradation of MO, ATA, 2,4-D, and MB in the ceramics TiO2 nanocomposites improved to about 0.264, 0.141, 0.302, and 0.368,respectively, after the UV irradiation for 240 min when 20 wt% TiO2 nanoparticle was added. In addition, the photocatalyticdegradation rate of photodegradation target materials was evaluated using the pseudo-first-order kinetics proposed by Lagergren.
