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.

Background: Peste des petits ruminants (PPR) is an infectious disease caused by the peste des petits ruminants virus (PPRV) that mainly produces respiratory symptoms in affected animals, resulting in great losses in the world's agriculture industry every year. Single-domain variable heavy chain (VHH) antibody fragments, also referred to as nanobodies, have high expression yields and other advantages including ease of purification and high solubility. Objectives: The purpose of this study is to obtain a single-domain antibody with good reactivity and high specificity against PPRV. Methods: A VHH cDNA library was established by immunizing camels with PPRV vaccine, and the capacity and diversity of the library were examined. Four PPRV VHHs were selected, and the biological activity and antigen-binding capacity of the four VHHs were identified by western blot, indirect immunofluorescence, and enzyme-linked immunosorbent assay (ELISA) analyses. ELISA was used to identify whether the four VHHs were specific for PPRV, and VHH neutralization tests were carried out. ELISA and western blot analyses were used to identify which PPRV protein was targeted by VHH2. Results: The PPRV cDNA library was constructed successfully. The library capacity was greater than 2.0 × 10⁶ cfu/mL, and the inserted fragment size was approximately 400 bp to 2000 bp. The average length of the cDNA library fragment was about 1000 bp, and the recombination rate was approximately 100%. Four single-domain antibody sequences were selected, and proteins expressed in the supernatant were obtained. The four VHHs were shown to have biological activity, close affinity to PPRV, and no cross-reaction with common sheep diseases. All four VHHs had neutralization activity, and VHH2 was specific to the PPRV M protein. Conclusions: The results of this preliminary research of PPRV VHHs showed that four screened VHH antibodies could be useful in future applications. This study provided new materials for inclusion in PPRV research.

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.

This study is to evaluate whether economies of scale exist in four categories of university libraries in the Korea. Regression analysis is used to fit a log-log equation to the total budget-output (total circulation, interlibrary lending and borrowing, reference transactions, hours opened, volumes added, automation and information indicator) for all the types of libraries. In results of the analysis, returns to scale are almost constant in the national and public libraries and larger libraries. But there is presence of economics of scale in private libraries and all of the libraries. Except for hours opened, economies of scale decrease more rapidly.

A thermal desorption-gas chromatography/mass spectrometric method was developed for the determination of methyl bromide in fumes formed during preservation of cultural materials from insects. Methyl bromide in lunes was collected by drawing 10ι of air through the adsorbent tube filled with a solid adsorbent (Chromosorb). The air samples were analyzed by using a special thermal desorption device and GC/MS determination. The recovery of methyl bromide by air sampling was 88% and the detection limit of the assay was 0.1 pptv based upon assayed air of 10ι. The method was applied to the determination of fumed methyl bromide used for the preservation of papers in a library. The mean concentration of methyl bromide determined in a library was 280.2 $\pm$ 25.4 pptv.

Surface emissivity and its background values according to each sensor are mandatorily necessary for Mid-Wavelength Infrared (MWIR) remote sensing to retrieve surface temperature and temporal variation. This study presents the methods and results of Land Surface Emissivity (LSE) of the MWIR according to land cover over the Korean Peninsula. The MWIR emissivity was estimated by applying the Temperature Independent Spectral Indices (TISI) method to the Visible Infrared Imaging Radiometer Suite (VIIRS) band 4 Day/Night images ($3.74{\mu}m$ in center wavelength). The obtained values were classified according to land-cover types, and the obtained emissivity was then compared with those calculated from a standard Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) spectral library. The annual means of MWIR emissivity of Deciduous Broadleaf Forest (0.958) and Mixed Forest (0.935) are higher than those of Croplands (0.925) and Natural Vegetation Mosaics (0.935) by about 2-3%. The annual mean of Urban area is the lowest (0.914) with an annual variation of about 2% which is by larger than those (1%) of other land-covers. The TISI and VIIRS based emissivity is slightly lower than the ASTER spectral library by about 2-3% supposedly due to various reasons such as lack of land cover homogeneity. The results will be used to understand the MWIR emissivity properties of the Korean Peninsula and to examine the seasonal and other environmental changes using MWIR images.
