Search engines, web portal sites, online book stores are being the main stream of information network. Library and its catalog has not influenced as the way it had been to the information network any more. Thus, institutions leading the bibliographic network started to pay much attention to the web user service. This article firstly reviewed the development of the bibliographic network, next generation catalog interface and OPAC 2.0, and investigated the case of OCLC in detail. Based on the reviews, this study suggested the development plan of bibliographic network focusing on the web user service in terms of the three strategies. It is hoped that this article will be the basic study for the future of the bibliographic network and the reference for the changes and improvements of libraries and catalog services.

Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes. This study clarified if there is Pareto principle in Korean universities' academic information resource sharing network and calculates the Gini efficient about inequality in sharing academic resources. As a result, top 20% libraries led 80% of performance and inequality degree showed 0.8 as very serious condition. Relative Gini efficient which is recalculated considering scale of each libraries stay 0.7 that is adjusted slightly down. It means that such phenomenon is not caused by the difference of each universities scale with high contribution of big university and low contribution of small university. And in comparison of inequality between university's types, inequality between community colleges and private universities is more serious than four-year-course college and national university respectfully. Finally, as a result of visualizing the distribution of participating libraries, there were libraries with overwhelming contributions, and libraries with small but relatively high contribution levels were also distributed.

We designed a self-timed interface circuit for efficient communication in IP (Intellectual Property)-based system with high-speed self-timed FIFO and a set of self-timed event logic library with 0.25um CMOS technology. Optimized self-timed standard cell layouts and Verilog models are generated for top-down design methodology. A method for mitigating a design bottleneck when it comes to tolerate clock skew is described. With clock control method and FIFO, we implemented high-speed 32bit-interface chip for self-timed system, which generated maximum system clock is 2.2GHz. The size of the core is about 1.1mm x 1.1mm.

This research focuses on how users behave when they search by subject using online public access catalog(OPAC). Major findings are as follows. 1)Main access poults are subject field$(55.2\%)$and title field$(42.2\%)$. 2) The search failure rate in subject searching is $59.3\%$. 3) Ma]or reasons for subject search failures are two-fold : use of inappropriate search terms $(48.5\%)$ and non-use of Boolean Operators$(42.5\%)$. 4) In order to overcome search failures users tend to change originally used search terms$(42.0\%)$ and search fields$(33.8\%) into different ones.

This study is a survey of collection development policies in the 40 university libraries among 42 in Korea as of 1984. The survey used a questionnaire with 36 questions concerning the basic elements of the collection development policy. The survey results revealed many problems demanding correction. The measures to correct the problems in the university libraries are as follows. 1. It is desirable that the libraries should have a collection development policy statement written and adopted for the systematic collection building. 2. It is advisable that the libraries should include a function of the materials selection among other various functions of the Library Committee for the purpose of informing administrators of the goals of the libraries and the validity of the budgetary allocation. 3. It is desirable that each library should organize the Collection Development Committee for minimizing the possibility of personal bias on the part of the individual selectors. 4. It is advisable that the primary responsibility for materials selection should be delegated as follows: for the materials for faculty research, to the faculty members; for the other collections, to the professional staff of each department; for the final review of whether or not to purchase, to the Collection Development Committee. 5. It is desirable for the purchase priority of materials to be set up in accordance with the order of 6 levels of collection development. 6. It is advisable that the libraries should, as top priority, purchase materials in direct su n.0, pport of the undergraduate and graduate academic programs, and in subject matter areas other than languages and literature, Korean materials should have not only the higher priority than the foreign language materials, but also maintain the comprehensive collection level. 7. It is desirable that the special collections should be purchased by special funds from the authority, and the special collections librarian should have the responsibility of the materials selection under the advice of the faculty members relating to the subject area. 8. It is advisable that duplicate copies should be bought only for high use items, but for reserve books, by the program enrollment, and textbooks should not be bought in general, except as su n.0, pplemental materials for course work in which they are necessary and heavily used. 9. It is reasonable that the material budget should be distributed as follows: by the ratio for distributing funds, about 60-70% for the library and 30-40% for departments; by the type of materials, about 50% for books, 40% for periodicals and 10% for other materials, or when not bought other materials, about 50-60% for books and 40-50% for periodicals. In addition, it is desirable that undergraduate class enrollment, graduate class enrollment, undergraduate majors, graduate majors, average book cost in the discipline, number of faculty, and use rate by subject should be considered as the factors for the allocation of funds by department, and special consideration should be given to newly-founded departments so the library holdings can be adequate to su n.0, pport them.

Prisons are mostly filled with social deviants and like other correctional institutions, deserve organized information (provision) centers such as library. A study on library resource needs and accessibility by prison inmates was conducted at Kuje prison, Abuja and Kaduna prison, Kaduna, Nigeria, both of which have functional libraries. A sample of 898 inmates was randomly selected from all the convicted inmates in the two prisons. A total of 106 inmates were selected from Kuje prison and 792 from Kaduna prison. A well-structured questionnaire was used to collect data from the inmates. All the 898 inmates responded. A total of 786 (87.9%) males and 112 (12.4%) females were involved in the study. With regards to the educational level attained by the inmates, 347 (38.6%) had Junior Secondary School Certificate while 323 (30.0%) had Senior School Certificate both accounting for 74.6% of the sampled population. In areas of information needs, 94.5%, 96.1%, 98.7%, 99.4%, 100%, and 100% of the respondents indicated that information on current affairs, survival and coping, educational support, legal aid, skill acquisition, and health, respectively were highly needed by the inmates. Out of the 12 information resources listed, only newspaper, novel, handbook and manual, and bulletin were readily accessible with percentage accessibility of 60.7, 7.8, 6.8, and 1.9, respectively. One major reason adduced by the respondents for limited access to information resources was the very strict rules and regulations in the prison. Providing more library resources and granting the inmates more access to the library would assist in character reformation and rehabilitation of the inmates.

This study intends to 1)conform the possibility to transform the enumerated scheme into the faceted scheme, 2)review general theories on facet structure employed in DDC 780, and 3) analyze the facet structure of music. Findings are 1) The facet structure of DDC synthesize the standard subdivisions or specific facet indicators with basic facet. 2) facet indicator 0 is in use to indicate standard subdivision or general principle of music. and facet indicator 1 to general principles and musical forms. DDC has transformed the entire system into the facet structure through its revisions. Especially the music transformed into the facet structure employes the facet indicators and applies them to all the systems in music. But the notation have sometimes twofold meanings, and no ability to differentiate the meanings in the same notation.

In the last decade, nuclear medicine appears to be a good choice of medicine. ⁵⁸Co, ⁹⁹Mo, ⁹⁹Tc, ⁹⁹Re, ¹³³Xe and ¹⁸⁶Re are very important radionuclides for nuclear medicine. In this study, the excitation functions of ⁵⁸Ni (n, p) ⁵⁸Co, ⁹⁹Tc (n, p) ⁹⁹Mo, ⁹⁹Ru (n, p) ⁹⁹Tc, ¹³¹Xe (n, p) ¹³¹I, ¹³³Cs (n, p) ¹³³Xe and ¹⁸⁶Os (n, p) ¹⁸⁶Re nuclear reactions were calculated at neutron energies between 1 and 20 MeV using TALYS 1.95 and EMPIRE 3.2 nuclear codes. Furthermore, the cross sections were calculated with the empirical formula derived in our past study at 14-15 MeV. The obtained results were compared with the measured values in EXFOR library, and with the evaluated data of (JENDL-4.0/HE, JEFF-3.3, TENDL-2019, ENDF/B-VIII.0, IRDFF-II, JENDL/ImPACT-18). The results are in good agreement with those of the evaluated data libraries and experimental results and indicates that these radioisotopes can be produced by smaller cyclotrons.

The purpose of this study is to identify the degree to which the card catalog in a university library serves its users and to provide useful information for the design of conversion from card catalog to online catalog. From August 19th to September 16th 1995, 278 users of Duksung Women's University Library were randomley selected and surveyed in terms of card catalog use, success rate of card searching, and catalog use training received. Major findings are as follows: 1. Taking into considerations the fact that Library users tended to use more heavily oriental card catalog$(61.8\%)$ than western card catalog$(8.3\%)$ or classification card catalog$(26.3\%)$, oriental card catalog should be designed to improve its search function of the catalog. 2. It was found that the university library card catalog was not easy to use by $49.3\%$ of the users of Duksung University Library. 3. One of main reasons why the card catalog is hard to use is that there is no subject card to which users can access for subject searching. Besides, users have difficulties in locating appropriate classification numbers for subjects which users are interested in. 4. When success rate is defined as finding appropriate cards in catalog boxes, the success rate was reported to be $87.0\%$. 5. The major access points of known items which library users utilized mostly were author$(18.3\%)$ and title$(74.5\%)$. 6. In case of translated versions of foreign materials, original author name cards instead of pronounced original name card written in Korean were given to them as access points. $79.9\%$ of library users of Duksung Women's University insisted that both original and pronounced author name writ':en in Korean should be given as access points to foreign authors for the sake of user's convenience. 7. Formal training programs for card catalog use were found not to be sufficient. Small group informal training courses should be offered to users who need to get information for catalog use by library staffs. 8. Considering the trend that orders of access points have been changed from title, author and subject in card catalog to title, keyword, and author in online catalog, the existing card catalog of Duksung Women's University is expected not to meet future users' needs for subject searching unless the funcions of subject searching of catalog is improved.

The purpose of this study is to analyze the effects of the bestseller ranks on the book circulations in public libraries. To achieve this goal, the weekly data sets of 179 books' library circulation and bestseller list from January 1, 2018 to December 29, 2019 were constructed based on the data collected from BigData MarketC and YES24. Three methods for analyzing panel data including linear regression, fixed-effect, and random effect models were compared, and it turned out that fixed-effect model was better than other methods. The results show that the average ranks of bestsellers were associated with their public library circulations visually. Also, the analysis of fixed-effect model showed that the single rank decline of a book on the bestseller list decreases its average circulation of 0.108 while the size of effect varied depending on subject of books. The study empirically demonstrated the impact of a bestseller list on people's book circulation behavior, suggesting that public libraries need to reference sociocultural context as well as bestseller book lists to predict library user needs and to formulate collection development policy.
