This paper is intended as a basic study in which the purpose is to provide understanding of the workings of man in relation to his information resources. Such understanding would prove of value in formulating the policies of an inoformation center serving the fields of science and technology. The information problem of the scientific community was assessed in the lights of the characteristics of the information (cumulativeness, currency versus obsolescence, volume versus redundancy, interrelationships, and foreign literature)and the flow of information and communication patterns covering the use of the variety of media and the information gathering habits of scientists. What can be done to ease the problem was sought in the improvements and innovations which call the attentions of the scientists and the technologists as producers and users of the information, of the professional organizations of various disciplines and of government.

The recent situation on developments in an expanding field of reference and information service is reviewed through the cooperative arrangements and comprehensive planning among libraries in America. The growth of reference cooperation is examined first along with the social forces that influenced the library interdependence for service. Of the various interlibrary programs identified in relation to the cooperative reference work, interlibrary loan is viewed as the key to the use of library resources based on equal access and making use of the tools for information and research, therefore a reference principle. Several kinds of library systems specifically intended to improve the reference situation are identified and described in detail without any attempt to evaluate their performance in terms of unit size, cost, or quality of the service.

In this study, I have tried to examine the movable type font called 'Chwijinja' (聚珍字) as hitherto and the book printed in Chwijinia for the first time. In order to illustrate the orgin of it more clearly, I introduced Bubyeogru-jungsugi(浮碧樓重修記.) which has been believed the first printed edition of this book and also some other books printed in the same movable type font. By the way, I introduced some views of other bibliographers on Chwijinja. I refuted the views that Chwijinja is metal type and then I substantiated it is wooden type. I also presented three hypotheses on the formation of Chwijinja. I described the reason why we had better change the name of that printing type into 'Bang-Chwijin-pansig Pilseoche Wooden Type'(倣聚珍版式筆書木活字) on the basis of that its name is common noun. I also explained about 'Yeonmu Wooden Type'(燕貿木(唐)字, Wooden Type font imported from China) which is relevant to my description.

The library as a social agency must study and evaluate its effectiveness and seek to improve its service for achieving the external objectives for which it was created. The study is an attempt to define the determining factors involved in change in library service. Library service evolves as a consequence of social need, which comprises unconventional demands of emerging areas in the subject ratio of literature, change in methods of research, change in the educational level of the community, and change in the user behavior. Since the library is an agency of communication, growth and specialization of information, and increase in variety of information media have effects on library service. The library is one of the many communication agencies in society, and increase or decrease in their programs can be determining factors of change in library service. Today, libraries depend more and more upon interlibrary cooperation to allow them to overcome their limitation in resources and time, and they can bring about changes in their service by adjusting themselves to the interlibrary cooperation arrangements available. Finally, library service is rendered as a result of theorizing as to what the library might or should do, and naturally theories or change in them may be determining factors of library service.

The magazine in mordern society is a powerful mass-media. Children are generally interested in magazines, which are relatively in expensive, readily and reguarly, and easy to read. The research chose 5 children's magazines published in Korea in 1973 for close analysis. The Sonyon (Youth) was found to be closer to a pure literary reading for children; the Sae Sonyon (New youth) and Sonyonsegeh (World of the youth) were purposes oriented toward popular amusement purposes carrying a great number of catoons; the Sonyon Chungang (Chungang youth) carried too many advertisements; and the Okae Dong Mu (Rear group) was rather weak in contents in fine contrast with its colourful appearance. The following characteristics were generalized from analysis of the five children's magazines published in Korea: (1) The function of periodic information dissemination was very weak, feared in danger of being wiped out. : (2) The educative and guidance function was found rather weak. (3) Economic motives seemed stronger in spite of the expressed zeal for missions of magazine. (4) In terms of contents variety was lackey, with little individuality for each magazine. (5) Generally emphasis was given to pictoral contents rather than to reading articles.
