The purpose of this study is to investigate the characteristics of 'The Big Read(TBR)' reading initiatives sponsored by the National Endowment for the Arts(NEA) in the U.S.A. TBR was originally launched to improve the seriously low level of literary reading among the American adults reported in several NEA reports, and spread to more than 500 communities. The major characteristics of TBR include the following: First, a massive investment of federal funds as well as various private and corporate donations; Second, the strong recognition of libraries as the core of reading activities in communities; Third, the adoption of the model of 'One Book, One Community' reading promotion campaign; Fourth, the provision of high quality resources for reading activities.

The purpose of this study is to understand the characteristics of books selected for 'The Big Read' community reading initiative of the National Endowment for the Arts from 2006 to 2017 and its relation with 'One Book, One City' community reading campaign in the U.S.A. An analysis of 1,407 TBR programs and 745 participating communities, and 56 books from TBR Library shows that TBR expands and complements 'One Book' reading campaigns, and confirms the sustenance of this innovative model. TBR Libray books were selected with TBR's own criteria, but their features are generally very similar to those of 1,102 books selected for 'One Book' programs. They often reflect some interests in such universal values as coming of age, justice, integrity, etc. and diverse cultural experiences and life. The outcomes of 'One Book' and TBR cannot be qualitatively measured, but their sustainable value of communication through one selected book has been well proved.

The purpose of this study is to understand the value of the book, To Kill a Mockingbird by Harper Lee as the most favored 'One Book' and the goals of the 'One Book, One City' programs which selected this particular book. A total of 86 'One Book' programs from 2001 through 2014 and 138 The Big Read programs from 2007 through 2015 selected To Kill a Mockingbird as 'One Book' to read. With this book, many communities discussed the sympathy toward the dignity of human being with such subjects as courage, justice, and integrity, and presented its value through book discussions, various programs and events.

Compressed filesystem is frequently used in the embedded system to increase cost efficiency. One of the drawbacks of compressed filesystem is low read performance. Moreover, read-ahead mechanism that improves the read throughput of storage device has negative effect on the read performance of compressed filesystem, increasing read latency. Main reason is that compressed filesystem has too big read-ahead miss penalty due to decompression overhead. To solve this problem, this paper proposes new read technique considering kernel read-ahead mechanism for compressed filesystem. Proposed technique improves read throughput of device by bulk read from device and reduces decompression overhead of compressed filesystem by selective decompression. We implement proposed technique by modifying CramFS and evaluate our implementation in the Linux kernel 2.6.21. Performance evaluation results show that proposed technique reduces the average major page fault handling latency by 28%.

The purpose of this study is to examine the characteristics and continuity of 'One Book, One City' community reading campaign in the U.S.A. An analysis of 584 'One Book' projects registered in the Library of Congress, the Center for the Books shows that this innovative model of reading campaign has been diffused through three stages: the beginning(1998-2001), the growth (2002-2006), and the second take-off(2007-present). The stability of more than fifty 'One Book' projects was confirmed and the continuing diffusion of 'One Book' model through 'The Big Read' Initiative and some projects' attempt to try new directions seem worth observing.

In this study, examined are the characteristics of 'One Book, One City' reading campaigns conducted in Seattle. Chicago, and 'The Big Read', a nationwide 'One Book' campaign, supported by the NEA, in the U.S.A. and Seoul and Cheongju in Korea. Some differences as well as similarities were found in the goal setting, selection of books, strategies for reading and discussion, and programs of these 'One Book' reading campaigns. While, as a mass reading event, 'One Book' reading campaigns in various communities share the goal of promoting literacy and communication through reading and discussion, each 'One Book' campaign seems to show uniqueness in the criteria of book selection, reading and discussion guides, and the activities and Programs. which make up cultural contents.

The purpose of this study is to understand the value of Fahrenheit 451 by Ray Bradbury as the second most favored 'One Book', and the goals of the communities which selected this particular book. A total of 53 'One Book' programs from 2001 through 2014 and 136 TBR programs from 2007 through 2015 selected this book as 'One Book' to read. In this study, 270 programs in TBR 2008/09, and more than 240 programs in TBR 2014/15 and several 'One Book' projects were analyzed. The results confirm the significance of book discussions and movie showing, the focus on such subjects as censorship, banned books, and freedom of expression, etc., and a close relationship between the diversity of programs and cooperation with community members.

The memory coherence problem occurs while mapping shared virtual memory in a loosely coupled multiprocessors setup. Memory is considered coherent if a read operation provides same data written in the last write operation. The problem is addressed in the literature using different algorithms. The big question is on the correctness of such a distributed algorithm. Formal verification is the principal term for a group of techniques that routinely use an analysis that is established on mathematical transformations to conclude the rightness of hardware or software behavior in divergence to dynamic verification techniques. This paper uses UPPAAL model checker to model the dynamic distributed algorithm for shared virtual memory given by K.Li and P.Hudak. We analyse the mechanism to keep the coherence of memory in every read and write operation by using a dynamic distributed algorithm. Our results show that the dynamic distributed algorithm for shared virtual memory partially fulfils its functional requirements.

If a file system is damaged because of the unusual system close, the system performs the consistency test using fsch and it takes long time. Especially, if it is a big file system, it will take a lot of time. The journaling file system that uses journaling technique, can reduce the restoring time because it uses meta data and it may increase the chance of restoration when restoring. The goal of this paper compared performance evaluation journaling file systems focused on the reading and writing using Iozone tool which is the kernel based benchmarking tool in linux operating system. In this paper, Ex4 which is the current basic Linux file system. is 1.28x faster than XFS file system in terms of file read performance and 1.22x faster than Ext3 file system in terms of file write performance.

Blockchain is a distributed ledger that combines technologies such as cryptography, consensus mechanism, peer-to-peer transmission, and time stamping. The rapid development of blockchain has attracted attention from all walks of life, but storage scalability issues have hindered the application of blockchain. In this paper, a scalable blockchain storage model based on Distributed Hash Table (DHT) and the InterPlanetary File System (IPFS) was proposed. This paper introduces the current research status of the scalable blockchain storage model, as well as the basic principles of DHT and the InterPlanetary File System. The model construction and workflow are explained in detail. At the same time, the DHT network construction mechanism, block heat identification mechanism, new node initialization mechanism, and block data read and write mechanism in the model are described in detail. Experimental results show that this model can reduce the storage burden of nodes, and at the same time, the blockchain network can accommodate more local blocks under the same block height.
