1969년도에 가금영양학자들은 가금영양학의 기초지식과 이의 응용분야에 대해 많은 연구결과를 발표하였다. 오늘날 가금영양학에 관한 연구는 크게 두 가지 분야로 대별된다. 첫째는 주요영양소의 생물학적 효율에 대한 보다 정확한 데이터를 얻는것과 특정 영양소의 정확한 요구량을 조사하는 기술 및 시험이며, 둘째 분야는 영양소들간의 상호작용과 대사과정의 효율성에 관한 정확하고 폭넓은 지식을 얻는 것이다. 이 시험집은 1969년도에 가금학자들이 연구발표한 가금영양학에 관한 하이라이트이다. 지면 관계로 전시험결과를 모두 수록치 못하였으나 사료공장이나 농장의 실제응용에 흥미가 많을 것으로 생각된다.

The field of information science has been documented in several ways during its existence and in some ways has mirrored that of other scientific disciplines during the same period. This article examines variables related to author gender of information science articles in American Documentation (AD) during its entire run, 1950 through 1969. Published by the American Documentation Institute, AD was a primary information science journal of its time, changing its name in 1970 to the Journal of the American Society for Information Science (JASIS), corresponding with the change of the parent organization's name to the American Society for Information Science (1968). AD was preceded by an earlier "information science" publication, the Journal of Documentary Reproduction (JDR), 1938-1942, issued by the American Library Association. Studies indicate that females contributed about 8% for the entire run of articles in JDR (1938-1942) and about 22% for the first twenty-seven years of JASIS (1970-1996). The present study explores the nature of female contributions to AD for the middle period (1950-1969). It has been determined that for the entire run of the journal under the name AD, female authors comprised about 17% of the contributors, which places their publishing percentage for this period between the earlier and later periods, thus expectedly filling the gap.

The outline of general trend on production, consumption and price of non-ferrous metals during 1969 is summerized in the paper. The production of every non-ferrous metals has increased compare to that of last year, and their consumption except silver has also increased. Specially the rate of growth of production is that; The rate of growth of consumption is such; The prices of gold and silver have decreased since last November due to the stability of international currency and the creation of S.D.R. at I.M.F., but those of other metals have increased, marking the price at the end of 1969 as follows: Cupper price of Foreign Refinery showed ¢72.471/lb(increased 39% per year), lead and Zinc jumped up to the highest price since the Korean War (1951-1953), showing the lead price ¢16.50/lb (increased 27% per year) and the zinc price ¢15.50/lb (increased 15% per year). Price of tungsten was higher than the agreed price that was made between Korea and U.S.A. during 1951 through 1954, showing $63.4/S.T.U. (increased 13% per year). The price of molybdenum was slightly increased from $1.62 to $1.72 (increased 6% per year). In summing up, the year of 1969 was the golden age for the nonferrous metals. It is, hawever, expected that in the next few years, the consumption rate and the prices of non-ferrous metals will be declined compared to those of 1969.

Dietary fiber(DF) intakes of Korean during 1969∼1990 were estimated and the major food sources of fiber were analyzed using the data from the Annual Reports of Korean National Nutrition Survey. The estimated daily DF intake of Korean has gradually decreased during the 22 years, from 24.46g in 1969 to 17.31g in 1990 with a remarkable decline in 1987. The average DF intakes of the rural population were higher than those fo urban's until 1980, but the situation was reversed until 1987 and the regional difference in DF consumption disappeared thereafter. Vegetables, cereals, grain and legumes were the major sources of fiber for Korean in recent 5 years(1986∼1990), providing 32%, 16% and 19% of DF intake respectively. Throughout the 22years, the intakes of DF from cereals and fresh vegetables have been reduced and those from processed vegetables, seaweeds and fruits has been increased. Df intake from legumes continuously increased until 1986, and it decreased thereafter. Rural population consumed more fiber from cereals than the urban's during the 1970s, but thereafter regional difference in cereal fiber intakes became insignificant. Urban population consumed more fiber from legumes and fruits than the rural's through the entire period. The results of this study indicate that the present DF intake of Korean is considerably lower than generally anticipated and is below the tentative recommended DF intake and thus higher DF intake than the present level is needed.
