In recently, housing market has changed from new construction to building' stocks maintenance, and from centered on the supplier to users. It suggests that the occupant should change the space form to adapt the life stage at any time. For this, open building is very effective to satisfy the occupant's requirements. Open housing is proposed as a alternative design methods not only to compromise user's various needs but also to be a means of sustainable development by adapting long-life of buildings. Open building could be required to evaluate the capacity-to-change at design stage whether it adapts or copes with the occupant's needs. The evaluation of capacity-to-change is very important to grasp how much open building has the function or performance. The capacity-to-change of open building can be measured through model which is organized and explained the support's attributed. This paper aimed at providing the model to grasp the capacity-to-change of open building with support's components and attributes. For this, it selected the support's factor explaining the capacity-to-change of open building, and the effective number of sample is 81. Various factors would be integrated or controlled through multidimensional scaling. The evaluation model would be set up, utilizing the backward regression method.

황은상,이광우,박돈희 전남대학교 촉매연구소 2001 觸媒硏究 論文集 Vol.22 No.-

The immobilization of Thiobacillus sp. IW, the hydrogen sulfide removing bacterium, was studied by using the adsorption and physical capture methods. In the case of immobilization by the adsorption, the type, size, and amount of polyurethane foam were affected by the cell immobilization capacity of supporter. Among supporters, MC-70 was better immobilizing material. The optimum size and amount of polyurethane foam were 5∼8mm and 8g/L, respectively. In the case of immobilization by the physical capture, polyurethane foam could be prepared with the same ratio of modified MDI prepolymer, polyol, and medium with better condition. The optimum size and amount of polyurethane foam were 6∼7mm and 8g/L, respectively. Considering the cell immobilization capacity, the immobilization by physical capture was more effective than the immobilization by adsorption. The immobilization intensity by adsorption was 85% after shaking for 24hrs, whereas the immobilization by physical capture was 92% under the same condit

The DXS52 locus was studied in a Korean population sample(n=142) for its allele and genotype frequencies and applicability to identity and paternity testing, using polymerase chain reaction with electrophoresis of PCR products and subsequent detection of allelic fragments by ethidium bromide staining. In Korean population, 15 alleles with the frequency range of 0.319-0.005 are detected in the DXS52 locus, and the highest allele frequency among them is found to be allele 1(0.319). The correlation coefficient between gene frequencies detected in female in mali is 0.9334, indicating that the gene frequency in males follows that of females in Korean population. This locus studied meets Hardy-Weinberg expectation : there is good agreement between the observed and expected values under Hardy-Weinberg equilibrium. The genotypes 1-12(0.118) are mostly frequent found among the 29 genotypes detected in Korean female, but the 91 genotypes are not found. The observed heterozygosity for this locus is 0.809, while the unbiased expected estimate of heterozygosity is 0.827 calculated by the expectation of Hardy-Weinberg equilibrium(p>0.05). The power of discrimination(PD) and power of exclusion(PEX) calculated for this locus is 0.9770(97.70%) and is 0.7068(70.67%), respectively. Thus, the allelic and genotypic data estimated for DXS52 locus can be used as the database of PCR-based DNA profile to human identity testing.

핵종의 지표 침적 모델의 고찰과 함께 방사성물질의 공기중 농도로부터 건침적 뿐 아니라 습침적에 따른 농작물 오염 영향을 분석, 고찰하였다. 이를 위해 방사성물질의 지표 침적량으로부터 농작물의 오염을 평가하는 기존 동적 섭식경로모델을 공기중 농도 또는 지표 침적량으로부터 평가할 수 있도록 개선하였다. 평가결과, 방사성물질의 지표 침적량은 습침적에 의한 영향이 건침적에 의한 영향보다 뚜렷이 높으나, 농작물의 오염정도는 핵종, 강우율 등에 따라 다르게 나타났다. 이러한 현상은 방사성물질의 지표 침적과 농작물에로의 차단중 어느 과정이 농작물 오염에 보다 지배적으로 작용하는가에 기인한다. Combined with deposition model onto the ground of radionuclides, the influence of radioactive contamination to agricultural products was analyzed due to wet deposition as well as dry deposition from radioactive air concentration during a nuclear emergency. The previous dynamic food chain model, in which initial input parameter is only radionuclide concentrations on the ground, was improved for the evaluating of radioactive contamination to agricultural products from either radionuclide concentrations in air or radionuclide concentrations on the ground. As the results, in case of deposition onto the ground, wet deposition was more dominant process than dry deposition. While the contamination levels of agricultural products were dependent on the a variety of factors such as radionuclides and rainfall rate. It means that the contamination levels of agricultural products are determined from which is more dominant process between deposition on the ground and interception onto agricultural plants.

This study was carried out to investigate the effects of the kinds and the amounts of dietary fiber on serum lipid composition in rats. Seventy-two male Sprague-Dawley rats weighting 160±10g were fed diets containing 1.0%, 3.6%, 6.0% and 10.0% α-cellulose, pectin and alginic acid for 4 weeks. Daily food intake of experimental groups was significantly higher in the α-cellulose 10.0% group than in the other groups. Increasing the dietary fiber level decreased the food efficiency ratio of the α-cellulose, pectin and alginic acid groups. Serum triglyceride concentration was significantly lower in the rats fed the alginic acid diet. Serum total cholesterol concentration showed no significant difference in the kind and the amount of three dietary fibers. Serum HDL-cholesterol concentration was higher in α-cellulose and pectin diet. HDL-cholesterol/total cholesterol ratio was higher in α-cellulose and pectin diet than alginic acid diet. In conclusion, alginic acid is good for the serum triglyceride decrease, pectin is good for HDL-cholesterol increase, α-cellulose and alginic acid are good for HDL-cholesterol/total cholesterol ratio increase. But the different effects according to the dietary fiber's contents did not show a significant trend.

食品加工素材로서 Glycosyl Sucrose의 特性에 관한 硏究

黃恩姬 圓光大學校 1986 論文集 Vol.20 No.2

설탕에 대용할 수 있는 甘味料로서 설탕에 여러 가지 길이의 glycosyl sucrose (coupling-sugar)를 사용하였을 경우 食品의 物性에 미치는 영향에 대하여 검토하였다. 설탕, coupling-sugar 및 물엿의 粘度와 粘彈性을 回轉粘度計와 粘彈性 Spectrometer을 사용하여 측정 비교하였고, ovalbumin의 熱變性 溫度와 澱粉의 糊化溫度에 미치는 영향은 高感度 示差走査熱量計를, ovalbumin의 起泡性과 그 安定性은 mixer와 mass sylinder를, 옥수수 澱粉gel의 rheology는 Rheometer와 Hardmeter를 각각 사용하여 측정하였다. 그 결과 coupling-sugar는 粘性 및 動的 彈性率이 물엿보다 낮아 Newton 流體의 성질을 가졌으며, coupling-sugar의 첨가에 의해 ovalbunin의 熱變性 溫度 및 澱粉의 糊化溫度가 상승되었고, 설탕 첨가시보다 전분geldml 硬度, 付着性, 凝集性을 증가시켰으며, ovalbumin의 起泡性 및 安定性을 증가시켰고, 카라멜화 반응은 설탕첨가시보다 덜 일어났으나 Maillard 반응은 더욱 촉진시키는 것으로 나타났다. In this study, the effect of substitution of coupling sugar (C-sugar) for sucrose on the physical characteristics of some foods were investigated.; 1) C- sugar appears in the form of jelly like maltose syrup. However the viscosity and dynamic elasticity of C-sugar was rather similar to sucrose that a Newtonian syrup. This suggested that C-sugar was rather similar to sucrose that a Newtonian fluid is. 2) Addision of C-sugar raised the heat-denaturating point of ovalbumin or gelatinization point of starch, the point of raised linearly with the concentration of C-sugar. 3) The hardness, gumminess, cohesiveness and viscosity of starch gel were increased by addition of C-sugar than sucrose. 4) C-sugar has stronger effects than sucrose on the foaming ability of ovalbumin, and the foam produced was more stable comparatively. 5) C-sugar was less sensitive to caramelization, but more sensitive to Maillard reaction than sucrose. These results suggest that C-sugar possesses some excellent characteristics as a replacer of sucrose for food processing.
