  • We designed a portable parallel library HPCL(High Performance Computing Library) with following objectives: (1) to provide a close relationship between the parallel code and the original sequential code that will help future versions of the sequential code and (2) to enhance performance of the parallel code. The library is an interface written in C and Fortran programming languages between MPI(Message Passing Interface) and parallel programs in Fortran. Performance results were determined on clusters of PC's and IBM SP4.

  • Recently, the expansion of smart phones, wi-fi. and unlimited service changed our life style from personal computer based to mobile device based. With this trend, a lot of companies and government facilities use QR code as an advertising material, and now the QR code is very popular service in our ordinary life. In the meantime, libraries in abroad and university libraries started using QR code in library service about 2 or 3 years ago, and domestic libraries started using it in service due to the increase of establishment of mobile Library websites. In this research, starting with looking into the literature, I analyzed the examples of the use of QR code in libraries. On the base of it, I drew a QR code library service model, and what needs to be considered for the use of it.

  • Librarians long ago proclaimed themselves professionals. Until recently, however, librarians and information professionals gave very little thought to professional ethics, which have corne to play an increasingly important role in all areas in modern society. They have been stimulated to consider their specific domain within an ethical context now. Professional norms express obligations which include prescribing standards, principles of responsibilities, and rules of duties. Professional codes attempt to formulate the norms of professional ethics and are the basis for disciplinary measures of various kinds. This paper discusses professional properties and characteristics of libarianship with a special reference to the code of professional ethics. The codes of ethics of the American Library Association, the Library Association, and of the Japanese Library Association have been reviewed and compared. The arguments on the enforcibility of the professional codes of ethics, therefore, on their effectiveness have been discussed. Author concludes that, despite some doubts on the practical effectiveness of the ethics code expressed by a number of scholars, a code of ethics is very much required in the information professions. Properly disseminated, a code would enhance the status and standing of the profession by demonstrating concerns for the maintenance of the highest possible level of standards of professional services. It would also play an important role in raising consciousness of the clients by communicating the value of the works.

  • The purpose of this study is to investigate material designation in library cataloging and to suggest General Material Designation (GMD) and Specific Material Designation(SMD) in Korean. A summary of the study follows. In library cataloging, methods of indicating the type of material are : (1) color-coding, (2) media code as part of the call number, (3) material designation in physical description area or note area, (4) GMD and SMD. GMD is a term indicating the broad class of material to which a bibliographic item belongs. SMD is a term indicating the special class of material to which a bibliographic item belongs. GMD was listed in parenthesis following the title proper before AACR1975 code, but currently it is listed in square brackets after the AACR1975 code. AACR2 was the standard cataloging rule in GMD and SMD terminology. It is suggested that GMD be used in Korean for graphic material, sound recordings, drawings, microform, multimedia, videorecordings, manuscripts, photographs, slides, printed music, motion pictures, printed texts, objects, braille, cartographic materials, computer files and transparenies.

  • Fuzzing is used to find vulnerabilities for a library. Because library fuzzing only tests the implemented functions, in order to achieve higher code coverage, additional functions that are not implemented should be implemented. However, if a function is added without regard to the calling relationship of the functions in the library, a problem may arise that the function that has already been tested is added. We propose a novel method to improve the code coverage of library fuzzing. First, we analyze the function call graph of the library to efficiently add the functions for library fuzzing, and additionally implement a library function that has not been implemented. Then, we apply a hybrid fuzzing to explore for branches with complex constraints. As a result of our experiment, we observe that the proposed method is effective in terms of increasing code coverage on OpenSSL, mbedTLS, and Crypto++.

  • The fundamental reason why most SQL injection detection methods are difficult to use in practice is the low reusability of the implementation code. This paper presents a reusable SQL injection detection method for Java Web applications based on AOP (Aspect-Oriented Programming) and dynamic taint analysis, which encapsulates the dynamic taint analysis processes into different aspects and establishes aspect library to realize the large-grained reuse of the code for detecting SQL injection attacks. A metamodel of aspect library is proposed, and a management tool for the aspect library is implemented. Experiments show that this method can effectively detect 7 known types of SQL injection attack such as tautologies, logically incorrect queries, union query, piggy-backed queries, stored procedures, inference query, alternate encodings and so on, and support the large-grained reuse of the code for detecting SQL injection attacks.

  • The objective of the study is to develop the identification code of the Korean sci-tech journals for KSCI. To achieve the purpose, the study has researched and analyzed a variety of the major international and national serials or information objects identification code systems. And then, KOJIC(KOrean Journal Identification Code) has been developed. KOJIC is unique, unambiguous identifiers for titles of Korean journals in all subject areas. The concepts of KOJIC are simplicity, mnemonics, internationalization, and extensibility of its use. KOJIC is a six-character and alphanumeric code and has one check character.

  • Recently there have been an increase in number of new library buildings and its users due to the demand of lifelong learning and cultural experiences of the local community and also the extension to their opening hours. At the same time there have been a growing number of problem users in local libraries. This seems closely associated with an increase in number of unemployment rates and their mental health issue. This causes a great challenge to the local libraries. in particular, to the front-line librarians. If these challenges are not dealt appropriately at all levels within the library organization the overall quality of services is likely to degrade leaving the general users dissatisfied and the staff adversely affected. Therefore in this study we propose a charter of library service and a library code of conduct to meet the aforementioned challenges and enhance the overall quality of library services.

  • Recently many documents have been written by HTML due to the expansion of the Internet and WWW. HTML allows scripting languages to interact between an user and an browser. Sometimes there might have problems with some functions of the script language. Some functions have the same name although the different contents and vice versa. It presents tremendous difficulties to maintain the functions. And, a file includes many functions shared among documents. If a user tries to see a HTML document, the file will be sent to the web browser in the user system. The network resource is wasted due to moving all data in the file through the network although some functions in the file is not used. So, we should design and implement the code library of a script language with a database. Each function has the name and arguments. A system of the code library manages functions with them. The system has the functions consistency and reduces the network resource consumption because there are only necessary functions in documents. Beside it is easy for the system to modify and reuse the functions.
