현대사회는 지식$\cdot$정보사회이며, 도서관은 지식과 정보가 전달되는 중요한 경로 중의 하나이다. 그렇지만 여러 가지 요인에 의해 도서관의 장서는 그 생산과 수집, 그리고 축적의 과정에서부터 편견과 왜곡으로 인한 굴절과 편향을 멀 수밖에 없었으며. 그것은 결과적으로 도서관이 현대사회의 지식$\cdot$정보의 유통기관으로서의 본질을 흐리게 만드는 주된 요인이 되어왔다. 이 연구는 장서연구의 필요성과 주요 해결 과제, 그리고 그 방법론에 대한 고찰이다. 장서 연구는 도서관장서의 축적 과정에 초점을 맞추어 그 장서가 편향성을 띠어 가는 과정을 추적하고 그 편향성의 현단계를 밝히는 작업이 그 출발점이 되어야 할 것이다.

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.

이 연구는 공공도서관 생태계의 담론화를 통한 개선 확장 전략을 제시하는데 목적이 있다. 이를 위하여 자연생태계의 순환원리와 구성요소에 근거하여 공공도서관 생태계의 기본원리와 구조적 지형을 해명하고 현주소와 인식을 분석하였다. 이를 바탕으로 다양한 관점과 시각을 차용한 전략적 방안(카르마 법칙을 적용한 도서관의 정체성 및 공공성 보장, 미네르바 신드롬을 극복하기 위한 사서직의 주체성 및 전문성 강화, 파레토 원리를 응용한 자료서비스 및 장서관리의 최적화, 부정적 후광효과를 해소하기 위한 일반열람실 축소와 비교우위 프로그램서비스 제공, 가우스 분포를 준수한 생애주기별 이용편차 해소, 이카루스 역설을 반추한 디지털 패러다임 수용과 이용친화형 공간화, 그레샴 법칙의 경계를 위한 작은도서관의 공공도서관 시스템화, 그리고 폼페이 역설을 반면교사로 삼은 소통강화와 사회문화적 가치 확산 등)을 제안하였다.

Objectives: The purpose of this study was to conduct a systematic review and meta-analysis of in vitro studies regarding the effectiveness of reciprocating and rotary instrumentation on microbial reduction in root canals. Materials and Methods: PubMed, Scopus, Web of Science, the Cochrane Library, and the gray literature were searched through December 2019. Studies comparing the influence of reciprocating and rotary instrumentation on the removal of microorganisms from root canals that quantified the antimicrobial effect were included. Data extraction was completed using a systematic form for data collection. The risk of bias of the studies was evaluated. Standardized mean differences (SMDs) and confidence intervals (CIs) were calculated using a random effects meta-analysis. Results: Seventeen in vitro studies were included in this systematic review, of which 7 provided adequate data for inclusion in the meta-analysis. Both reciprocating and rotary systems were similarly effective in reducing the microbial load in infected root canals (SMD [95% CI], 0.0481 [-0.271, 0.367]). Three studies showed a low risk of bias, whereas most of the studies (82%) presented a medium risk. Conclusions: Although both techniques decrease the microbial content (with reductions of 23.32%-88.47% and 23.33%-89.86% for reciprocating and rotary instrumentation, respectively), they are not able to provide complete disinfection of root canals.
