Although breast milk is the best food for infants, there will always remain a need for good substitutes when breastfeeding is not possible. Most of these substitutes are based on cow milk, but soy milk has been used as an alternative. It is necessary to ascertain that rearing infants on these formulas yields results comparable to those obtained by breastfeeding. Absorption of trace elements such as iron and zinc is well known to be higher from breast milk than from cow milk formula while absorption from soy formula is lower than from cow milk formula. The studies on the contents of iron and zinc in breast milk, cow milk formula and soy formula, and the intakes and blood levels of iron and zinc in infants fed breast milk, cow milk formula and soy formula, and the intakes and blood levels of iron and zinc in infants fed breast milk and cow milk formula were reviewd. The contents of iron and zinc in artificial formulas were higher than those in breast milk, and the intakes lf iron and zinc in infants fed cow milk, formula were higher than those in infants fed breast milk, However, the blood levels of iron in infants fed cow milk formula were significantly lower than those in infants fed breast milk, and there was no significant difference in the blood levels of zinc between infants fed cow milk formula and those fed breast milk. No results have been reported on the iron and zinc nutriture in Korean infants fed soy formula. More research should be focused on the potential consequences of excessive intakes of iron and zinc in infants fed soy formula as well as cow milk formula.

웹 상에서 QoS 제공을 위한 Diff-HTTP

현은실,이윤정,김태윤 고려대학교 컴퓨터과학기술연구소 2001 JOURNAL OF COMPUTER SCIENCE & ENGINEERING TECHNOLO Vol.3 No.-

HTTP 프로토콜은 WWW에서 HTML(HyperText Markup Language)문서를 송수신하기 위해 사용하고 있는 애플리케이션 프로토콜로서 TCP를 수송 계층 프로토콜로 이용하여 이루어지는 애플리케이션 계층 프로토콜 가운데 하나이다. HTTP/1.0은 동일한 서버로부터 각각의 개체에 대하여 개별적인 TCP 연결을 생성하기 때문에 다중의 요구를 비효율적으로 처리한다. 이러한 문제를 해결하기 위한 방안으로 제안된 HTTP/1.1은 TCP 연결을 지속적인 연결(Persistent connection)이라는 개념을 도입하여 하나의 TCP 연결 상에서 다중의 요구(Request)를 처리하도록 하고 있다. 네트워크가 발전됨에 따라 사용자가 늘어나고 다양해지면서 서비스의 차별화 문제가 중요한 문제로 대두되었다. 본 논문에서 제시하는 Diff(Differentiated)-HTTP은 웹 서버에 서비스를 요청한 클라이언트들에게 차별화된 서비스를 제공하기 위해서 사용자를 두 등급, 기본 등급과 우선 순위를 고려한 상위 등급으로 구분한다. 각 등급은 제한 시간(Holding Time)으로 차별화 되고 상위 등급에 속한 클라이언트에게 제한된 시간을 증가 시켜 지연을 최소로 함으로써 고품질의 서비스를 제공하는 방안을 제시한다. The HyperText Transfer Protocol(HTTP), the Web's application-layer protocol, is at the heart of the Web. HTTP/1.0 establishes a new TCP connection for each HTTP request, resulting in many consecutive short-lived TCP connection. HTTP/1.1 standard reduces latencies and overhead from closing and re-establishing connections by supporting persistent connections as a default, which entourage multiple transfers of objects over one connection. HTTP/1.1, however, does not define explicitly connection-closing time but specifies a certain fixed holding time model. This paper proposes the mechanism of a Diff-HTTP((Differentiated-HTTP) supported by the server-side under HTTP/1.1. The current World-Wide Web services model treats all requests equivalently, while being processed by servers. Based on the policy, different levels of service are desirable. This paper presents, service-side, application-level mechanisms to provide each different level of web service with upper class and default class. Our experiments show that upper class latencies are reduced than default one.

A dietary survey with 24-hour recall method was performed to female college students, and the food intake data were converted to nutrient intakes using two different computer programs. The mean daily energy intake calculated with DS24 program was 1598kcal(79.9% of RDA) while 1840kcal with CAN program. The mean intake of other nutrients was also mostly higher with CAN program than with DS24 program. Therefore, when we assess nutrient intake using CAN program, we must consider the possibility of the overestimation of the intake before interpreting the data. Each 24-hour recall was evaluated for the consumption of items from the dairy, meat, grain, fruit, and vegetable groups. Failure to consume any foods from the fruit, meat, and dairy group was reported by 60.9%, 30.4%, and 21.7% of the subjects, respectively. Consumption of food from all five food group was associated with higher nutrient intake. The results emphasize the need for nutrition education directed at increasing the diversity of the diet. The index of measuring diet quality will be further evaluated.

엄기태,함현식 명지대학교 대학원 1997 대학원논문집 Vol.1 No.-

The methane combustion reaction was conducted over Pd-ZSM-5 catalysts in order to get a total combustion of methane. ZSM-5 synthesized at low temperature and atmospheric pressure was used as a support. The change of methane conversion with changing SiO_2/Al_2O_3 molar ratio was tested. And, the methane conversion of the synthesised ZSM-5 catalyst was compared with a commericial ZSM-5. The methane conversion was increased with decrease in SiO_2/Al_2O_3 molar ratio. Methane combustion reaction rate was also increased with decrease in SiO_2/Al_2O_3 molar ratio. The synthesised ZSM-5 showed better methane conversion than that of the commericial one.

박현호,박태현 성균관대학교 생명과학자원연구소 1994 生命資源科學硏究 Vol.1 No.2

Factors influencing the biodegradability of polymer materials by municipal sewage sludge were studied using starch, polyethylene glycol(PEG) and polyvinyl alcohol(PVA). The degree of biodegradability was determined by measuring evolved carbon dioxide as a function of time, when the polymer material is exposed to activated sewage sludge. The biodegradability of starch reached around 70% and 40% after 30day incubation in summer and autumn, respectively. This is caused by the activity of microorganism and incubation temperature. The biodegradability of PEG 8000 and PVA was 1/7 and 1/14 of starch, respectively. Biodegradation of PEG 8000 after 30 day incubation in summer was slightly higher than that in spring while lag phase was significantly longer in spring. This shows that the activity of microorganism as well as incubation temperature is important for biodegradation.
