鳥取県立図書館所蔵の往来物資料について ― 目的別と出版地域別の分類整理 ― CiNiiでみる

著者名:
郡 千寿子 

抄録:
鳥取県立図書館に所蔵されている近世期版本の往来物資料について、調査した概要を報告する。和本のみの目録はなく、『鳥取県立図書館 和漢籍分類目録―鳥取県立鳥取図書館旧蔵―』1)『鳥取県立鳥取図書館 郷土資料目録昭和54年3月31日現在』2)により調査し、調査対象に該当すると思われる近世期の往来物資料を選別した。加えて文献調査を実施し、考察検討のうえ分類整理した。 総数では、28本の近世期版本の往来物資料が確認された。目的別に分類してみると、教訓科往来が5本、社会科往来は所蔵がなく、語彙科往来が1本、消息科往来が14本、地理科往来の所蔵がなく、歴史科往来が3本、産業科往来が3本、理数科往来の所蔵はなく、女子用往来が2本という結果であった。出版地域別の分類では、江戸が6本、京都が10本、大坂が3本で、不明が9本という結果であった。地理的に近い京都の出版が最多であり、関西圏からの影響が大きかったことが予想される。しかし、江戸の出版は、大坂より多く、不明が9本存在することを合わせて考えると、江戸文化圏からの影響が必ずしも少ないとはいえないであろう。すでに公表している島根県立図書館での調査結果との比較検討も行い、地域の偏在状況や格差についてもグラフ化して提示した。  往来物の分布を通して、地域の教育的背景の格差や文化伝播状況などを解明することを目的としているが、本稿は、島根に次ぐ山陰地域の調査地点である。従来、山陰地域の往来物資料は『往来物解題辞典』でも記載が少なく、調査の空白地帯であった。今後、他地域の状況と比較する上で基盤となる調査の一報である。

緊急事態宣言解除直後の図書館の新型コロナウイルス感染拡大予防対策の評価 ?ある図書館でのキャプション評価の実施 CiNiiでみる

著者名:
松原 茂樹 

抄録:

This study aims to record COVID-19 infection control in detail and to evaluate this in one library. Caption evaluation method was carried out in late June 2020. The evaluation near the counter was generally good in terms of measures to avoid gathering and information presentation. However, in terms of contact, there were many bad evaluations such as handicapped items, copiers, leaflets, etc. Prioritizing the development of user areas, the area where staffs work was not developed. It is significant that the evaluation was carried out because a third party pointed out that the staffs alone had overlooked them.

Rumpfr: A Fast and Memory Leak-free Rust Binding to the GNU MPFR Library CiNiiでみる

著者名:
Tomoya Michinaka  Hideyuki Kawabata  Tetsuo Hironaka 

抄録:
The GNU MPFR library for arbitrary-precision floating-point arithmetic is widely used, and its Foreign Function Interface bindings to various languages have been developed. For the Rust programming language, existing bindings to the MPFR library include gmp-mpfr-sys (a low-level binding) and Rug (a binding that utilizes gmp-mpfr-sys to provide a more user-friendly interface). However, neither has sufficient descriptiveness and performance as bindings for general users of Rust, which is a programming language featuring high memory safety and high speed. We have developed a Rust binding, Rumpfr, to the MPFR library, that offers an easy way to write programs that perform high-speed multiple-precision floating-point computation. Rumpfr provides an interface that follows that of the MPFR library but hides the complexity of managing the mantissa area of floating-point numbers from the user. Rumpfr uses Rust's variable-length arrays to allocate mantissa areas, making it easy to handle without compromising Rust's high memory safety. In this paper, we describe the design and implementation of Rumpfr and present the results of numerical experiments demonstrating that Rumpfr can be used to write programs with low overhead.------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

PelemayFp: An Efficient Parallelization Library for Elixir Based on Skeletons for Data Parallelism CiNiiでみる

著者名:
Susumu Yamazaki 

抄録:
In this presentation, we propose Pelemay Fast Parallel map (PelemayFp), which is a library to parallelize Elixir code, efficiently, based on skeletons for data parallelism. PelemayFp is implemented using only Elixir, like Flow, which is a library of previous works. In Flow, the order of the list after computation is not guaranteed, while in PelemayFp, the order of the list is guaranteed because it is sorting while collecting and merging. On the other hand, Pelemay Super Parallelism (Pelemay), which we proposed, generates native code using SIMD instructions and calls it by NIFs, which is one of FFIs that Erlang provides, without performing multi-core parallelism, guaranteeing the order of the list. We evaluated the integer arithmetic performance by logistic mapping of PelemayFp alone, Pelemay alone, the combination of PelemayFp and Pelemay, Flow, and Enum, which is in the standard library of Elixir. When run on an Intel Xeon W-2191B CPU with 18 cores and 36 threads, the PelemayFp alone is up to 2.1 times faster than Enum. It is also faster than Flow without sorting. On the other hand, the combination of PelemayFp and Pelemay is up to 1.27 times faster than Enum. We also estimated the percentage of parallel execution in the entire code based on Amdahl's law. That of PelemayFp is 48-66 percent, while that of the combination of PelemayFp and Pelemay is 21-46 percent. Further analysis revealed that this experimental results can be explained by assuming that when calling native code from Elixir with NIFs, the part that is not executed in parallel increases by about 40 percent. Therefore, when generating native code including SIMD instructions and adopting the approach of parallelizing with Elixir for speeding up, it will be appropriate to incorporate a code optimization mechanism using SIMD instructions into the JIT, which will be released in the next major version of Erlang, or to use another FFI method, Port, instead of using NIFs.In this presentation, we propose Pelemay Fast Parallel map (PelemayFp), which is a library to parallelize Elixir code, efficiently, based on skeletons for data parallelism.

金田平一郎旧蔵書 CiNiiでみる

和仁 かや  梶嶋 政司  山根 泰志  宮嶋 舞美 

抄録:
昭和初期から第二次世界大戦直後の九州帝国大学法文学部で法制史講座を担った金田平一郎博士の旧蔵書は,没後その多くが九州大学に納入され長らく分散排架されていたが,70年近くを経てこの度集約・文庫化に至った.本稿ではかかる経緯や目録リストを含めた概要とともに,復元された旧蔵書から判明する金田の関心や当時の学問環境の一端,並びに新規寄贈資料から明らかとなった『御触書集成』刊行にまつわる知見を紹介し,「文庫化」という営為が齎す意義についても考察する.
