  • 국내 도서관의 양적, 질적 성장에 따라 도서관의 장서 수와 이용자 수가 급증하고 있으나, 이에 따른 도서 관리의 어려움 또한 증대되고 있다. 특히, 도서가 지정된 서가에 위치해 있지 않아 이용자들이 도서를 찾는데 어려움을 겪는 경우가 빈번하다. 이러한 문제의 해결을 위해 본 연구에서는 RFID 기술을 이용하여 보다 편리하게 도서의 위치를 파악할 수 있는 도서 검색 시스템인 'R-LIM(알림)' 시스템을 개발하였다. 'R-LIM' 시스템을 활용하면 도서의 현재 위치를 실시간으로 파악할 수 있어 도서를 보다 쉽게 찾을 수 있을 뿐만 아니라, 도서를 정위치 시키는데 소요되는 시간도 크게 줄일 수 있다. 이 방식은 도서도난방지 등의 부수적 효과도 가져올 수 있다.

  • In the modern society, Archives are an available subject to the people of a nation and it is indispensable to build and appropriate access environment in order to connect the users and the registered records stored in the facilities. Specially, the Closed Shelves Access system, based on the notion of "a Policy of Archives Preservation", needs to be fully equipped with an access environment more adequate to its necessities. Hence, this study has analyzed all sorts of environments-institutional, organizational, human, physical and intellectual- from a general perspective in order to activate users to read the archives and based on this, the objective of the research is in proposing a program that effectively provides archives to the users and provides the basis for putting into practice an active access environment. The use of archives is the fountainhead in order to preserve archives. By using the archives, the meaning of preserving them is maximized. Whether these archives may be used or not will depend on the quality of information and the advancement of the access environment. Therefore, in order to motivate users to access the archives, first of all the facilities and the archivists must establish norms regarding the access, based on statutes and once they have been settled, they should provide other changes such as ; the development and fixation in the organization's structure, the education of specialized human labor, the expansion of physical space and the facilities and diverse positive services.

  • The Ross Sea, Antarctica plays an important role in the formation of Antarctic Bottom Water (AABW) which is the densest water mass in global thermohaline circulation. Of the AABW, 25% is formed in the Ross Sea, and sea ice formation at the polynya (ice-free area) developed in front of ice shelves of the Ross Sea is considered as a pivotal mechanism for AABW production. For this reason, monitoring the Ross Sea variations is very important to understand changes of global thermohaline circulation influenced by climate change. In addition, the Ross Sea is also regarded as a natural laboratory in investigating ice-ocean interactions owing to the development of the polynya. In this article, I introduce characteristics of the Ross Sea described in previous observational studies, and investigate variations that have occurred in the Ross Sea in the past and those taking place in the present. Furthermore, based on these observational results, I outline variations or changes that can be anticipated in the Ross Sea in the future, and make an appeal to researchers regarding the importance and necessity of continuous observations in the Ross Sea.

  • The construction method of scaffolding structures is different from Mortise and Tenon and bucket arch structure of traditional large woodwork. It forms an independent construction system-fixing nodes with knots, a large number of diagonal braces are used to fix shelves and the structures mostly contain X-shape and triangular shape details. Simple ones include stalls, sheds, rain sheds, altars, lamp racks etc. But the scaffolding with larger scale and more complicated structure are modeled on archways, theatres and other buildings which are used in commercial and festival activities. At present, Macao, Hong Kong, Guangdong, Sichuan, Shanxi and other places in China have retained the custom of using scaffolding structures in important festival activities, but their uses, techniques and building types are slightly different from place to place. Due to building and demolishing at any time, the construction and service cycle is short. As a result, there are almost no physical objects left. We can only deduce the use and technical characteristics of ancient scaffolding skills through the colorful building styles that have been preserved with folk activities in various parts of China, the craftsmanship handed down from generation to generation by the scaffolding guild and artisans, and the description of cultural and historical materials and the mutual corroboration of visual materials.

  • 한국이 일본에 병합되면서 갑오개혁~대한제국기 공문서는 조선총독부(朝鮮總督府)로 인계되어 과(課) 단위의 분류체계에서 부(部) 단위로 재분류되었지만, 그전에 몇 번의 재분류과정을 거쳤다. 재분류의 흔적은 갑오개혁~대한제국기 공문서철 표지에 찍힌 분류도장과 창고번호도장에서 확인된다. 분류도장에서는 '부(部)-국(局)-과(課)' 행정체계에서 과(課)를 단위로 문서철을 구분하고 분류도장을 찍고 호수를 부여하였다. 이는 대한제국기 공문서 분류체계와 동일한 것으로, 분류도장을 찍을 당시까지도 課를 단위로 한 분류체계는 유지되었다. 분류도장은 과(課) 단위로 구분하고 각 문서철에 호수를 부여하였지만, 과(課) 하위단위의 분류체계는 과(課)별로 차이가 있었다. 지세과(地稅課) 문서철은 한 호수에 여러 기관이 등장하고 문서연도는 앞뒤 호수에서 중복되었고, 같은 성격의 문서철이 따로 분류되어 있었다. 관세과(關稅課)와 잡세과(雜稅課) 문서철은 문서연도를 기준으로 편철된 두 과(課)의 편철 방식을 반영하여 문서연도를 기준으로 호수를 부여한 것으로 보여지지만, 문서연도와 'イロハ 가(歌)' 순서가 맞지 않았다. 갑오개혁~대한제국기에는 공문서를 과(課) 단위로 편철하였지만, 課 하위단위의 분류규정이 없어 분류도장의 문서철 분류를 대한제국기 공문서 분류체계의 원질서로 파악할 수 있는가의 여부는 명확하지 않다. 그러나 편철 방식은 문서 분류체계를 반영하므로, 편철 방식을 통해 대한제국기 과(課) 하위단위의 분류체계를 추론해 본다면, 분류체계는 '과(課) - 거래기관'과 '과(課) - 문서연도' 두 체계로 구분되었을 것으로 이해된다. 조선총독부는 대한제국기 공문서를 인계받고 창고에 보관하면서, 각 문서철에 창고번호도장을 찍었다. 창고번호도장은 대체적으로 각 창고별로 문서를 편철한 기관을 구분하여 문서철을 보관하였다. 각 창고의 서가에도 대체적으로 분류도장 호수 순으로 문서철을 배열하였지만, 일부 문서철은 호수가 뒤섞여 서가에 배열되어 서가와 호수 순서가 맞지 않았다. 서가에 문서철을 배열한 다음 각 문서철에 'イロハ 가(歌)' 순으로 기호를 부여했지만, 기호 역시 호수 순으로 부여된 것은 아니었다. 조선총독부가 각 창고에 문서철을 보관하는 과정에서 분류도장의 분류체계가 해체되고 있었던 것이다. 창고번호도장에서 나타난 특징 가운데 하나는 분류도장에서 각 문서철에 부여한 보존기간의 의미가 사라지고 있다는 점이다. 보존기간은 해당 문서가 지닌 역사적 행정적 가치에 따라 결정된다. 그런데 창고번호도장에서는 보존기간의 구분 없이 같은 서가에 보존기간이 다른 문서철을 뒤섞어 함께 배열하였다. 일본은 한국을 병합하면서 대한제국기 공문서를 일정 기간이 지난 뒤 폐기해야 할 행정 문서가 아니라, 식민 통치에 필요한 '고고(考古)의 재료(材料)'로 취급하였다. 일반 행정문서에서 식민 통치에 필요한 재료로 문서의 가치 평가가 전환되면서, 문서철에 부여된 보존기간에 상관없이 대한제국기 공문서를 모두 동일한 대상으로 취급하여 함께 보관하였던 것이다. 조선총독부는 식민 통치에 필요한 재료로 활용하기 위해 갑오개혁~대한제국기 공문서를 재정리하면서 부(部)를 단위로 재분류함으로써 대한제국기의 과(課)를 단위로 한 기관별 분류체계와 그 속에 포함되어 있던 기능별 분류의 성격도 해체하였다.

  • The statistics of recent accidents in warehouses show that a heavy toll of lives were produced by various accidents, e.g. collision, overturn, fall, slip, exposure to harmful substances or environments, etc. Of significant concern amongst them is the collision, especially the collision between forklift and storage rack structure. Accordingly, this study focuses on behavioral characteristics of rack structure subjected to dynamic impact loading of a forklift. For this purpose, time-domain response analysis has been performed on a standard 2-bay six-story rack structure consisting of columns, beams and bracing members with perforated open section. In order to investigate the most critical scenario, the impact loads are applied in both down-aisle and cross-aisle directions, and the impact locations are also varied along the shelves of the palettes. In order to deal with storage distributions, three types of rack structures are further taken into account: original empty rack structure with no storage, half-loaded rack structure and fully-loaded rack structure. The numerical simulation results demonstrate that the dynamic characteristics of the rack structure are significantly dependent on the distribution of the storage goods and its natural period varies from 0.24sec to 1.06sec, approximately 4.4 times. Further, the parametric studies show that the forklift impact is most critical to the safety of the rack structure when it collides either at the base or at the top of the rack structure.

  • Three categories (freshwater, amphidromous, and marine fishes) of Taiwanese fishes are analyzed on the basis of zoogeographic elements, viz. China element, Indo-China element, Indo-West Pacific element, Indo-Pacific element, North-Pacific element, Japan-Oregon element, and circumtropical element. Freshwater fishes, which include the China and Indo-China elements, are distributed on part of the boundary area between the Palaearctic and Oriental regions of Wallace (1876). Diadromous fishes include the North-Pacific, Indo-China and Indo-West Pacific elements. Taiwanese salmon, a landlocked (initially diadromous) species that became established in Taiwan between 0.5 my B.P. and the early Pleistocene, is recognized as a distinct taxon included within the Oncorhynchus masou complex, which comprises here three species and two subspecies, viz. Oncorhynchus masou masou (Sancheoneo, Songeo, Sakura-masu or Yamame), O. masou ishikawae (Satsuki-masu or Amago), O. sp. (Biwa-masu), and O. formosanus (Taiwanese salmon), based on molecular, morphological and biological studies. Marine fishes are discussed under the following headings, brackish-water fishes (fishes of brackish waters and seas adjacent to continental coastlines, North Pacific and Indo-West Pacific elements; fishes of brackish waters and seas primarily around islands, Indo-West Pacific element), reef fishes (fishes of inshore reefs along continental coastlines from 0 to ca.100 m depth, Indo-West Pacific element; fishes of inshore reefs primarily around islands from 0 to ca.100 m depth, Indo-West Pacific element; fishes of offshore reefs along continental shelf edges from ca.150 to 300 m depth, circumtropical and Indo-Pacific elements; fishes of offshore reefs primarily around islands from ca.150 to 300 m depth, Indo-Pacific element), demersal fishes (fishes on continental shelves shallower than ca.150 m depth, Indo-West Pacific and Japan-Oregon elements; fishes on edges and upper continental slopes from ca.150 m to 500 m depth, Indo-West Pacific, Indo-Pacific, and circumtropical elements; fishes on lower continental slopes to abyssal plains from ca.500 m to 6,000 m depth, circumtropical element and rarely Indo-Pacific element), pelagic fishes (epipelagic fishes from 0 to ca.150 m depth, Indo-West Pacific, Indo-Pacific or circumtropical elements; meso- and bathypelagic fishes from ca.150 to 3,000 m depth, circumtropical element). The distribution of Taiwanese marine fishes are influenced by the Kuroshio Current, low-salinity and low-temperature waters from mainland China, and sea-bottom topography.

  • The purpose of this study was to set up the objective standards of a space design for preschool children's room. In order to perform the above purpose, this study was organized into three sections. First, literature review to understand the relationship between preschool children's development and children's room, design elements and correlated variables of children's room. Second, survey research to seek a standard of children's room size, necessary furnitures, prefeerred colors and motifs. Third suggestions of objective and concrete alternative plan through the literature review and survey research. The major findings from the survey research were summarized as follows : 1) The mean size of contempory preschool children's room was 3.1 pyong and that of ldeal room was 4.7 pyong. 2) Necessary Furnitures with which more than two-thirds of parents want to furnish were bed, wardrobe, chest of drawers, toy shelves, toy boxes, book cases, chalkboard. Necessary furnitures for different ages were found to vary. For the age 2-5, the funitures for play were major, where as for the age 5-6, the furnitures for study were major. 3) The colors of contemporary preschool children's room were red, yellow, pink, blue, those of parent's favorites were Light colors(pink, skyblue, lemon yellow, Light green, Light purple). The rooms for boy were found with more cold colors, those for girl with more warm colors. 4) The motifs of contemporary preschool children's room were plants, lines, figures from cartoons of fairy tales. Boy's parents prefreerd space science and vehicles, while girl's parents preferred sky scenery and plants for their children's room.

  • Ocean tides in Antarctica are not well constrained mostly due to the lack of tidal observations. Especially, tides underneath and around ice shelves are uncertain. InSAR (Interferometric Synthetic Aperture Radar) data has been used to observe ice shelf movements primarily caused by ocean tides. Here, we demonstrate that it is possible to estimate tidal constituents underneath the Sulzberger ice shelf, West Antarctica, solely using ERS-1/2 tandem mission DInSAR (differential InSAR) observations. In addition, the tidal constituents can be estimated in a high-resolution (~200 m) grid which is beyond any tidal model resolution. We assume that InSAR observed ocean tidal heights can be derived after correcting the InSAR data for the effect of atmospheric loading using the inverse barometric effect, solid earth tides, and ocean tide loading. The ERS (European Remote Sensing) tandem orbit configuration of a 1-day separation between SAR data takes diminishes the sensitivity to major tidal constituents including $K_1$ and $S_2$. Here, the dominant tidal constituent $O_1$ is estimated using 8 differential interferograms underneath the Sulzberger ice shelf. The resulting tidal constituent is compared with a contemporary regional tide model (CATS2008a) and a global tide model (TPXO7.1). The InSAR estimated tidal amplitude agrees well with both models with RMS (root-mean-square) differences of < 2.2 cm and the phase estimate corroborating both tide models to within $8^{\circ}$. We conclude that fine spatial scale (~200 m) Antarctic ice shelf ocean tide determination is feasible for dominant constituents using C-band ERS-1/2 tandem mission InSAR.

  • In order to understand the effects of all-trans-RA on palate development, RA was injected into the abdominal cavity of pregnant mice and then the embryos were taken in the following days and analyzed morphologically as well as molecular biologically. When RA was administered at the stage of E11 or E15, the overall craniofacial development was retarded. The length from jaw to eye was shortened, compared to that of normal group. When the E11 embryos were exposed to RA, cleft lip was also found along with the cleft palate. In vitro palate culture experiment also revealed that RA caused cleft palate. When RT-PCR was performed, early stage administration of RA at E11 inhibited the upregulation of Hoxa7 expression at E15 through E17. Whereas in control group, high level of Hoxa7 expression was detected in the palate of E15 to E17. In the case of Bax, the expression was decreased from E16, while remaining constant in control group. When TUNEL analysis was performed following the RA treatment at E15, TUNEL positive cells were detected in the mesenchymal cells as well as epithelial cells of palatal shelves of E16 and in E17 embryos. Whereas in normal control, TUNEL positive cells were observed mostly at the epithelium around the nasal cavity and oral cavity where rugae is made. These results altogether indicate that exposure to RA during palate development causes facial deformity including cleft palate and cleft lip by modulating the expression of homeotic genes such as Hoxa7 as well as an apoptosis-related gene, Bax, and thus malregulating the apoptosis.
