도서관의 기본적인 목적은 지식의 생산 전달 및 사회에 대한 봉사이다. 도서관은 장서 및 정보봉사를 통해 이러한 목적을 달성하는데 기여하는 것이 필수적인 구성요소이다. 이런 목표를 달성하기 위해 장서의 질을 개선함으로써 이용자서비스의 질을 한층 더 향상시키기 위해 장서폐기가 필요하다. 하지만 현재 우리 도서관계에서는 장서 폐기의 중요성을 어느 정도 인식하고 있지만 회피하는 경향이 있다. 이러한 이유로 각 도서관별 장서의 양에 따라 도서관의 순위를 매기는 정책 요인과 실무 요인, 행정 요인 등이 있다. 결국 장서폐기에 대한 필요성은 인식하고 있지만 쉽게 실천을 못하는 실정이다. 장서폐기는 부족한 서고 공간 문제에 대한 해결책이 될 수 있을 뿐 아니라 장서의 품질관리를 위해서도 필수적인 활동이다. 따라서 장서폐기에 대한 필요성과 그에 따르는 저해요인을 분석함으로써 현실적인 도서관 관리를 재조명하고자 한다.

Since the users have direct access to search and browse freely, the open access system has been employed to all the usual modern libraries. However, library space shortage problem created by the continuously increasing printed materials caused the degradation of usability and quality of the library space. Open Access system is superior in user convenience but is inferior in space efficiency. Keeping the open access system is considered as one of the reasons of the space shortage problem. Even though the closed access system does not provide free access or easy browsing for the uses, it's space efficiency is much higher than the open access system. The closed access system should be employed as a plan to relieve space shortage problem. Since the closed access system does not allow the public direct access to books, it is very economical. It also provides much better space efficiency with higher book shelving density. In this article, closed access library system models and their characteristics are examined as the reduction plans for the library space shortage problems.

The primary cause of missing teeth vary depending on the region. The loss of posterior teeth is mainly due to dental caries, whereas that of the anterior teeth occur primarily due to trauma at the age of standing and walking and secondarily from the rampant dental caries. Particularly, reduction of the arch length in the cases of premature loss of primary teeth may compromise the eruption of succedaneous permanent teeth. This may result in crowding and impaction of the permanent teeth, and asymmetry of arch, thus a careful consideration for space maintenance should be made in such cases. Space maintainer is required in the case of premature loss of primary posterior teeth, because space loss result from the approximate and centrifugal movement of the neighboring teeth. Generally, in the case of primary incisor, space loss occurs when 1) tooth contact is relevant, 2) crowding in primary dentition is present, and 3) a primary incisor is lost before the eruption of primary canine. Contrarily, in the case of primary dentition with interdental space, space loss will not be observed, mostly when a primary incisor is lost after the eruption of primary canine. Thus, using a space maintainer in cases of premature loss of primary incisor has been introduced primarily not for the purpose of space maintaining but for an aesthetic purpose, prevention of parafunctional oral habits such as tongue thrust, and of pronunciation. Additionally, few case studies have been reported of space loss in cases of premature loss of primary incisor. This study is to report cases of the space loss following the premature loss of primary incisors observed in children.

This paper examines urgent issues of establishing the presidential library in relation to the current standing of the Government Archives and Records Service. As government records have been tremendously accumulated every year, the Government Archives and Records Service will be full within three years, which indicates that the constructing of new storage repositories is an emergent issue. In addition, presidential records are one of the most significant and influential public properties for preserving historical value and interpretation at the national level. Some serious concerns relating to the presidential library are raised for consideration. First of all, it is compulsory to preserve presidential records and to construct the presidential library. Second, the presidential library performs a variety of functions including the acquisition, preservation, access, reference, research, education, and display of presidential records as well as exhibits of public activities and administration personally and in public during the president' regime. A new presidential library should function as both of a depository and museum of presidential records through systematic arrangement and display. Thus a new repository of the Government Archives and Records Service should be co-constructed with the presidential library within the same boundary. Third, a newly constructed presidential library should be at least double- or triple- sized more than estimated in order to contain all related holdings. Fourth, to take custody of public records across the legislature, judiciary and administration, the Government Archives and Records Service should be directed by an official at the level of vice-minister and upgraded to an independent office such as "National Archives and Records Administration." Fifth, the presidential library's location and surrounding environments should be selected with careful planning.

The archives preservation chamber is an equipment that is able to store important archives with air-cleaning and isothermal-isohumidity control functions to permanently store archives in a highly safe environment. The chamber can only store small amounts of archives but it is crucial for organizations preserving archives to economically store a variety of archives, be it a medium or a small amount of documents. An arm of this study researches the current preservation status of the local record center to determine the need for such a chamber. In addition, in order to improve the air-cleaning and isothermal-isohumidity functions, the researchers of this study have conducted analyses to design the core parts. The preservation chamber that had been designed includes an archives preservation area, air-cleaning equipment, and environment measurement equipment. A preservation chamber is used to preserve small amounts of important archives safely. Thus, when a local record center is preserving various types of archives in small or medium quantities in a stack room, the preservation chamber can be used to aid their long-term preservation.

Recently, the importance of users' geographic location information has been highlighted with a rapid increase of online social network services. In this paper, by utilizing geo-tagged tweets that provides high-precision location information of users, we first identify both Twitter users' exact location and the corresponding timestamp when the tweet was sent. Then, we analyze a relationship between the tweet frequency and the average user velocity. Specifically, we introduce a tweet-frequency computing algorithm, and show analysis results by country and by city. As a main result, it is shown that the tweet frequency according to user velocity follows a power-law distribution (i.e., Zipf' distribution or a Pareto distribution). In addition, by performing a comparison between the United States and Japan, one can see that the exponent of the distribution in Japan is smaller than that in the United States.

This study proposes the establishment of a joint preservation library in the Chungcheongbuk-do region. It aims to transfer low-utilization materials from various libraries in Chungcheongbuk-do to the joint preservation library, thereby improving the efficiency of existing spaces and actively supporting the educational curriculum of school libraries. To achieve this, the study conducted document analysis, a status survey, and case analysis. The research results indicate that a reasonable standard for the accommodating capacity of the preservation library space is calculated at 280 volumes per square meter. Specifically, an initial transfer of 45,580 volumes for public libraries and 121,894 volumes for school libraries is proposed, totaling 167,474 volumes. Depending on the saturation levels of Chungcheongbuk-do Office of Education-affiliated public libraries and school libraries, the initial volume is determined to be 167,477 volumes, with an annual increase of 10% calculated over 30 to 50 years after the library's opening.

Twitter, one of online social network services, is one of the most popular micro-blogs, which generates a large number of automated programs, known as tweet bots because of the open structure of Twitter. While these tweet bots are categorized to legitimate bots and malicious bots, it is important to detect tweet bots since malicious bots spread spam and malicious contents to human users. In the conventional work, temporal information was utilized for the classficiation of human and bot. In this paper, by utilizing geo-tagged tweets that provide high-precision location information of users, we first identify both Twitter users' exact location. Then, we propose a new tweet bot detection algorithm by using both an entropy based on geographic variable of each user and device information of each user. As a main result, the proposed algorithm shows superior bot detection and false alarm probabilities over the conventional result which only uses temporal information.

The purpose of this study is to describe the trends and contents of literature in green library and to suggest the research direction on green library. Earlier studies focus on the green library architecture and necessity, after then green library management studies have proliferated. Green library architecture studies have emphasized on 'energy and atmosphere' and 'indoor environmental quality' based upon 5 categories of LEED evaluation system. Green library management studies have focused on library resources recycling and utilizing energy through effective management of library collection. Based on the analysis of literature, five research directions are suggested, such as the number of libraries in an area, library shelf position and space, library space program, collection ratio for library storage, and user studies.

This case study analyzed how electronic journal subscription had an effect on special library management including budget, information behavior, library operations, facilities, space et al. in KIST. This study suggests the followings; 1) Since electronic journals has an effect on overall operations of special libraries, draw big pictures not by functions. 2) Though the most method for subscription is consortium, it is necessary to build cooperation network for information sharing and vary cost architecture of information use. 3) Through job analysis, redesign jobs. 4) Reconstruct stacks and facilities. 5) It is necessary paradigm shift that it is more important to use than preserve materials in the special libraries.
