For the utilization of protein isolates from swine liver, lung and bone in food, biochemical properties and microbiological safety of the alkaline-extracted protein isolates were examined. Chemical modification (succinylation) was attempted in order to increase the functional properties of protein isolates. The results obtained were summarized as follows: 1. The amino acids composition of the liver protein isolates was quite excellent except valine and isoleucine but other protein isolates had generally lower amino acids contents than FAO/WHO recommended chemical score. Especially, sulfur-containing amino acids were found to be a limiting amino acid. 2. During the extraction, protein seemed to undergo non-covalent interaction and disulfide bond formation bt in-vitro pepsin digestibility of the protein isolates was found to be 80-98%. The protein isolates had a very low amount of calcium and riboflavin. 3. Through succinylation of protein by succinic anhydride during alkaline extraction, the protein recovery, the solubility of the protein in distilled water, emulsion capacity, the oil absorption, the water hydration and whippability of the protein isolates were increased in some degrees. 4. The number of microorganisms in liver and lung were decreased dramatically during the alkaline extraction and protein isolates could be stored for longer than 15 days at-15℃.

In order to raise the utility of beef tallow, edible beef tallow was fractionated by an acetone crystallization procedure and utility of each fraction was examined. The results obtained are summarized as follows: 1. Edible beef tallow was effectively fractionated to yield five fractions. Iodine value, cholesterol and unsaturated fatty acids (C_(18:1), C_(18:2)) contents were increased and melting point and saturated fatty acids (C_(16), C_(18)) contents were decreased during the progress of fractionation. 2. It was assumed that the. solid fractions (melting point: 51-56℃) could be used as a substitute of hydrogenated oil and The semi-solid fraction (melting point: 37℃) as a cocoa butter in view of the thermal behavior of this fraction by differential scanning calorimetry. 3. Potato chips were manufactured using the liquid fraction as frying medium. The physico-chemical properties of the oil during the consecutive frying and the preference of the potato chips were examined. It was found that the liquid fraction could be used solely or when mixed with vegetable oil as inexpensive frying oil.

In order to make better use of pork by-products, being consumed unsanitarily at present, sausage was manufactured formulating of four different levels(20, 40, 60 and 80%)of pork by-products mixture(Liver: Lung: Stomach=2 : 1 : 1). And the effect of phosphate-complex levels ( 0 , 0.3, 0.6 and 0.9% ) on the quality of the sausage formulated with 40% pork by-products mixture was investigated during the storage period of 36 days at 5 ℃. The results obtained were summarized as follows; 1. The appropriate level of pork by-products mixture for the sausage was evaluated at 40%. 2. The flavor score, pH, water-holding capacity, emulsion stability and the redness were significantly increased while the V.B.N., T.B.A. value and yellowness of sausage were significantly decreased by the addition of phosphate-complex. However, the residual nitrite was increased significantly by the addition of phosphate-complex.

Purpose: We aimed to investigate the correlations between expressions of angiogenic cytokines VEGF-A, C, D of primary colorectal cancer and liver metastasis. Methods: We examined paraffin-embedded primary colorectal cancer tissue from 45 patients who had liver resection due to colorectal liver metastasis (metastasis group) and 37 patients who had surgical resection due to colorectal cancer only (control group). In the control group, local recurrence and distant metastasis had not occurred. Immunohistochemical staining for VEGF-A, C and D was performed. We analysed the correlations between expression of VEGF-A, C and D in primary colorectal cancer tissues and clinicopathologic parameters. Results: VEGF-A expressions of primary colorectal carcinoma were not different between the two groups. VEGF-C was more frequently expressed in the metastasis group (P=0.008) but VEGF-D was more expressed in the control group (P=0.003). Patients with VEGF-C negative and VEGF-D positive expression were predominant in the control group (P=0.020). Tumor location, T stage, lymph node metastasis and tumor differentiation were not related with the expressions of VEGF-A, C, D but only preoperative CEA was positively correlated with VEGF-A and C expression. Conclusion: Expressions of VEGF-C in primary tumor were more frequent in metastatic colorectal cancer and expressions of VEGF-D were more frequent in nonmetastatic colorectal cancer. More large-scale prospective studies for VEGF-C and D expression in colorectal cancer are necessary.

발포 Polyurethane에 점착하는 미생물 Biomass측정
송인상(Song In Sang),조대철(Cho Daechul),허남수(Huh Nam-Soo) 한국산학기술학회 2005 한국산학기술학회 학술대회 Vol.- No.-
미생물 고정화를 위하여 PU 폼을 세 가지 처리 방법으로 처리하였다. 플라즈마 처리, 플라즈마 유도 그라프팅, 플라즈마 유도 그라프팅 후 플라즈마로 재처리 방법을 사용하였다. 플라즈마 처리는 bacteria adhesion에 큰 효과를 주지 못하였고, 아크릴산의 플라즈마 유도 그라프팅은 adhesion을 세 배 이상 증가시켰다. Bacteria의 adhesion 성능 향상은 표면의 친수성을 증가시키고 새로운 groove나 cavity들을 형성시킴으로 가능하였다. 반면, 그라프팅 후 plasma re-treatment는 미생물 고정화를 크게 향상시키지 못하였다. SEM 관찰을 통하여 대부분의 E.coli.는 groove나 cavities라는 shear-free area에 서식함을 알 수 있었다. PU폼의 bacteria adhesion은 미생물과 고분자 표면 사이의 정전기적 인력이나 van der Waals 인력에 의해 주로 영향을 받는다고 사료된다.

의미적으로 확장된 태그들을 이용한 XML 문서들의 유사성 계산.

XML(eXtensible Markup language) 사용의 급속한 증가는 웹에 존재하는 많은 양의 정보들을 XML기반 데이터로 생성하게 했으며 저장과 교환에 있어서 표준이 되도록 했다. 이는 사용자에 의한 임의의 태그정의를 가능하게 하는 XML 사용의 용이성에 기반한다. 그러나 이러한 장점은 비슷한 내용을 갖는 XML 문서에 대해서 사람들마다 개개의 태그이름과 구조를 사용한다는 문제점을 만든다. 따라서 유사한 의미를 가지고 있지만 서로 다른 문서로 분류된다. 이러한 점을 개선하기 위해 XML 문서 태그들 간의 벡터 스페이스 모델과 XML 데이터를 이용하여 시소러스를 구축하는 방법 등이 연구되고 제안되어 왔지만 아직 초보적인 단계이다. 본 논문에서는 XML 문서를 구성하는 태그들을 동의어로 확장하여 벡터를 생성하고 생성된 벡터를 가지고 태그들 간의 유사성을 체크하여 서로 다른 XML 문서들의 유사성을 수치적으로 계산한다.

미세먼지(PM<sub>10</sub>)의 지역적 대푯값 산정 방법에 관한 연구 - 서울특별시를 대상으로
송인상 ( In-sang Song ),김선영 ( Sun-young Kim ) 한국지리정보학회 2016 한국지리정보학회지 Vol.19 No.4
Many epidemiological studies, relying on administrative air pollution monitoring data, have reported the association between particulate matter (PM<sub>10</sub>) air pollution and human health. These monitoring data were collected at a limited number of fixed sites, whereas government-generated health data are aggregated at the area level. To link these two data types for assessing health effects, it is necessary to estimate area-level concentrations of PM<sub>10</sub>. In this study, we estimated district (Gu)-level PM<sub>10</sub> concentrations using a previously developed pointwise exposure prediction model for PM<sub>10</sub> and three types of point locations in Seoul, Korea. These points included 16,230 centroids of the largest census output residential areas, 422 community service centers, and 610 centroids on the 1km grid. After creating three types of points, we predicted PM<sub>10</sub> annual average concentrations at all locations and calculated Gu averages of predicted PM<sub>10</sub> concentrations as representative Gu-estimates. Then, we compared estimates to each other and to measurements. Prediction-based Gu-level estimates showed higher correlations with measurement -based estimates as prediction locations became more population representative (R<sup>2</sup>=0.06-0.59). Among the three estimates, grid-based estimates gave lowest correlations compared to the other two(0.35-0.47). This study provides an approach for estimating area-level air pollution concentrations and assesses air pollution health effects using national-scale administrative health data.
