분리 대두단백의 소화율과 전기영동패턴에 미치는 Phytate의 영향

윤재영,조희경,이서래 이화여자대학교 생명과학연구소 1993 생명과학연구논문집 Vol.4 No.-

Phytate 함량이 다른 두 분리 대두단백(HSPI; high-phytate soy protein isolate, LSPI; low-phytate soy protein isolate)을 제조하여 pH 및 phytate 첨가량이 그들의 용해도와 소화율에 미치는 영향을 알아보았고 분리 대두단백을 용해도에 따라 분별한 후 그들의 특성을 전기영동을 통하여 알아보았다. LSPI와 HSPI 모두 분자량이 13.6~81.1 kDa 에 이르는 단백질 성분으로 이루어져 있으며 산성 pH에서 18.0~35.0 kDa의 단백질은 phytate와 잘 결합하지 않는 특성을 가졌다. LSPI를 용해도에 따라 분별하였을 때 gliadin을 구성하는 단백질은 pH2에서 phytate와 쉽게 결합하지 않았다. 대두 단백질은 pepsin 소화율은 phytate 첨가량이 증가할수록 크게 저하되었다. This study was carried out to examine the effects of phytate addition on the solubility and digestibility of the low-phytate soy protein isolate (LSPI) and high-phytate soy protein isolate (HSPI). In SDS-polyacrylamide gel electrophoresis of soy protein isolate, different patterns of proteins were observed in both HSPI and LSPI at various phytate and pH levels, suggesting that phytate may bind specifically to certain protein fractions at a particular pH. For example, proteins of M.W. 1.8~3.5kDa resisted phytate binding at acidic pH. LSPI was fractionated into albumin, globulin, gliadin and glutelin; and phytate was shown to bind with difficultly to all three gliadin bands. Effects of phytate on the pepsin digestibility of soy proteins were apparent, especially in the short term digestion.

Recently, many manufacturing companies had increased interests in supply chain integration activities between customers and suppliers and their performances. The reasons are increasing costs in manufacturing, faster life cycle of products and lack of scared resources. The purpose of this study is to search the literature about the supply chain integration activities among manufacturers, suppliers and customers. First, supply chain integration was composed of four ; logistics integration, supplier integration, purchasing integration, and information integration. Second, we try to verify the relationship between supply chain integration strategy, supply chain integration performance, and manufacturing performance. Third, we proposed the conceptual framework of supply chain integration and performance in manufacturing. This proposed model will be helpful for achieving competitive advantage and will be analyzed empirically in the near future.

Basal cell nevus syndrome(BCNS)is a hereditary condition transmitted as an autosomal dominant trait that exhidits high penetrance and variable expressivity. There ara many potential complications which have been reported in association with the naevoid basal cell carcinoma syndrome. The data upon which this review is based has been retrieved from published case reports in Korean dental and medical literatures between the years 1981 to 2002. this survey included unpublished 3 patients by reviewing patients files and charts from the Dental hospital, Chosun University during same periods. We found 33 subjects who met the diagnostic criteria for BCNS reported by Evans et al. Relative frequencies of associated complications are presented and compared with those of the recent English survey. The frequencies of most manifestations are similar. Odontogenic keretocyst (OKC)and palmar and/or plantar pits, and hypertelorism were the most frequently observed anomalies. OKCs are often the first signs of BCNS and can be detected in patients younger than 9 years of age. however, the relatively low frequency of basal cell carcinomas and ectopic calcification were two major difference. This study more clearly defines the possible complications of the syndrome and gives earlier guidelines for counselling and screening affected and at risk persons.

Metal balls are commonly used in mechanical elements and systems including bearings. If there is a defect in a metal ball, it can cause a serious machine failure. By this reason every balls produced are required to be inspected, and the inspection is usually done by human eyes. However, the inspection by human eyes is always with the risk of mistakes, and a need to automate the inspection process is arisen. This paper describes a design of an automatic inspection system for detecting defects on ball surface. A machine vision system is used, and design process and techniques are described in detail. 강구는 베어링을 비롯한 기계 요소 및 장치에서 널리 사용되는 부품이다. 만약 강구에 결함이 있을 시, 이를 사용하는 기계에서 치명적인 결함이 초래될 수 있다. 따라서 제조된 강구에 대해서는 전량검사가 요구되고 있고, 검사과정은 사람의 육안에 의한 검사가 주를 이루고 있다. 그런데 사람에 의한 검사에는 항상 실수의 가능성이 있으므로, 이를 자동화하는 것이 필요하다. 본 논문에서는 강구의 표면 결함을 자동적으로 검사할 수 있는 장치를 설계한다. 기계시각 장치가 사용되었고, 설계에 따른 구체적 절차와 기술들이 서술된다.

This study was to investigate the structural behavior of braced-frame systems with slit damper. For this study, push-over analysis was carried out to investigate the difference of structural behavior between the braced frame system without slit-plate dampers and the braced frame system with slit-plate dampers. The braced-frame systems with slit plate dampers were more effective than the braced-systems without slit-plate dampers: (1) The plastic hinges which were happened at damper were decentralized each story so that the plastic deformation of the main frames were decreased. (2) The ductilities of the former structure were increased.

Background : About 30% of patients in the hospital are under nourishment. A large portion of people are undernourished when they are admitted to the hospital and in the majority of these, undernutrition develops further while in hospital. Patient-Generated subjective global assessment(PG-SGA), a method of nutritional assessment based on clinical judgment, has been widely used to assess the nutritional status of adults for both clinical and research purposes. Modified PG-SGA can be used as a nutrition screening tool, and a comprehensive nutrition assessment is desirable for those who are malnourished. The purpose of this study is to develop a simple, reliable and valid nutrition screening program(NSP). Methods : We applied the nutrition screening program(NSP) to adult inpatients who are at risk of malnutrition using the Modified Patient-Generated subjective global assessment(PG-SGA) and objective assessment(electrical medical record data). Results : Therefore simple and beneficial NSP is developed for patients with severe malnutrition. Using NSP. nutritional information of the severe malnutrition patient should be shared with the physicians and they should be taken care of by clinical dietitians to improve their nutritional status. Conclusion : The Modified PG-SGA and nutrition screening tool are simple, reliable and valid nutrition screening program(NSP).
