  • This paper propose a novel VLSI architecture for a multiplierless FIR filter chip providing variable-length taps. To change the number of taps, we propose two special features called a data-reuse structure and a recurrent-coefficient scheme. These features consist of several MUXs and registers and reduce the number of gates over 20% compared with existing chips using an address generation unit and a modulo unit. Since multipliers occupy large VLSI area, a multiplierless filter chip meeting real-time requirement can save large area. We propose a modified bit-serial multiplication algorithm to compute two partial products in parallel, and thus, the proposed filter is twice faster and has smaller hardware than previous multiplierless filters. We developed VHDL models and performed logic synthesis using the 0.8.mu.m SOG (sea-of-gate) cell library. The chip has only 9,507 gates, was fabricated, and is running at 77MHz.

  • The skew-t distribution is an attractive family of asymmetrical heavy-tailed densities that includes the normal, skew-normal and Student's-t distributions as special cases. In this work, we propose an EM-type algorithm for computing the maximum likelihood estimates for skew-t linear regression models with censored response. In contrast with previous proposals, this algorithm uses analytical expressions at the E-step, as opposed to Monte Carlo simulations. These expressions rely on formulas for the mean and variance of a truncated skew-t distribution, and can be computed using the R library MomTrunc. The standard errors, the prediction of unobserved values of the response and the log-likelihood function are obtained as a by-product. The proposed methodology is illustrated through the analyses of simulated and a real data application on Letter-Name Fluency test in Peruvian students.

  • The objective of this study is to catch hold of the problem occurring in the process in which librarians have obtained government publications and to show the method that can construct the rational distribution system of government publications. For this study, total 56 librarians who work for 44 institutes sponsored by central government and 12 institutes sponsored by local government were chosen as the objects of research and questionnaire survey to know how to obtain government publications. How to construct the rational distribution system of government publications is as follows. (1) The exclusive organization to manage overall service for government publications should be established newly or previous similar organization should be reorganized. (2) As reinforcing the law concerning deposit copy, government publications should be distributed obligatorily to all of the depository agency, and the depository library system of government publications should be introduced and managed newly. Especially the management of deposit copy and the depository library system of government publications should be undertaken by the exclusive agency of government publications. (3) Free-government publications should be converted to pay-government publications as much as possible so that everyone can purchase government publications easily. And free-government publications which are difficult to convert to pay-government publications should be distributed according to rational standard by the exclusive agency of government publications. (4) Pay-government publications should be sold by private distribution organization under exclusive agency of government publications. Also printing, editing and pricing of pay-government publications should be done by private distribution organization to compete with general books. (5) In order to promote the sales of pay-government publications, the sales centers of government publications must be established even in city and county. Also special government publications which have much demand should be sold even in general book stores. Especially the management of the sales centers should be undertaken by private distribution organization. (6) It is necessary to abolish or improve unreasonable regulations or system related to government publications and to make legislative, institutional devices for government publications. (7) The public relations for government publications should be enforced much through TV or radio etc. , and the various bibliographic tools of government publications should be developed and disseminated for the sake of much utilization of government publications. (8) By using new technology like CD-ROMs or communication networks, electronic production and distribution of government publications should be push ahead positively. And electronic information distribution center to su n.0, pport it should be established by government agency.

  • This research is a case study that describes the NUCLIS21(Nuclear Information System 21), an integrated web-based information management system of KAERI(Korea Atomic Energy Research Institute), implemented to carry out the role of a national nuclear information center with government support as an information infra implementation programme. Through its user-centered single interface, the system aims at building an infrastructure for the national nuclear information center, as well as improving the information management system of the TID(Technical Information Department) within the institute. The system consists of two major parts which are an integrated module of the MIS and six different kinds of system. These include the Integral search system with OPAC, My Library, the Acquisition system, the Catalogue system, the Information Supply system, and the Serial Publication system. The DB is composed of Bibliographical DB, Original text DB and Abstract DB. A special feature of this system was designed as a unified network system through connection to MIS(Management Integration System) of the institute, so users can get research information for projects. Therefore, they have access to available information easily and access to the ongoing service of this system. Furthermore, users can share information by using our system. The survey has it that 75.7%(200 persons), 62.1%(164 persons) and 78.4%(207 persons) of the respondents are satisfied with the fidelity, speediness, and convenience of the system respectively, and the overall satisfaction of the respondents is comparably high.

  • This thesis investigated disabled students' actual status of applying for university libraries. This thesis investigated how many times the university disabled students utilized the libraries, if facilities, apparatuses, materials, and regular employees were operated properly, and if they were established actually on the target at thirty private university libraries located at Seoul and Gyeonggi regions in operation of specially screening the objective students for special education in 2008. The investigation found that the general operation level of university libraries for disabled students were less than "medium"(average 2.38). As for utilization ratio, the most university students responded that "they didn't utilize libraries so many times(60%)". As for the response ratio of university library facilities and services, the most university students responded, "very insufficient", 99 items(32.27%), and the least university students responded, "very excellent", 28 items(7.0%). On the other hand, as for the analysis of each field, building facilities, in all of the items, were established more than "medium"(average 3.26), but material preparation level(average 1.8 point), employee education for softly supporting disabled students, and library utilization education on the target at disabled students(average 1.87) were less than "insufficient". Especially, the field of service was "insufficient level"(average 2.48), and standard deviation was more than 1.4. Manpower stationing and material delivery services have the biggest standard deviation between universities. So, this investigation found that university libraries reformed access to facilities a lot, but that its level of fundamental policy for library, such as materials, manpower, and the education on utilization, were in insufficient level.

  • This study uses Gini coefficient to index the inequality of academic information resource among universities to identify the areas where the gap is extremely severe, and analyzes the Gini coefficient over time for 10 years to show how the gap is changing. In addition, the degree and characteristics of the gap appearing by type of universities such as metropolitan universities, local national universities, private universities, and colleges were also compared. As a result, first, the university library academic information infrastructure showed a severe level of disparity (0.6 - 0.9), and the inequality was more severe in serials, electronic resources, and reference service. Even when the relative Gini coefficient was calculated considering the number of students, the inequality was over 0.4 in serial etc. Second, the Gini coefficient trend over the last decade shows that the inequality has decreased toward equality in the re-education time of employees and electronic information resources, but not in other sectors. Third, it was found that special universities and universities in the metropolitan area showed a large gap between universities of the same kind, and local national universities showed the best gap level as well as the best academic information infrastructure.

  • This study aims to investigate the current status of young adult services centering on public libraries in Busan, Ulsan and Gyeongnam, identify problems, and then suggest tasks for service revitalization. The status of young adult services and librarians' perceptions in the 93 public libraries in Busan, Ulsan, and Gyeongnam that were registered in the 2021 National Library Statistics System and the Busan Metropolitan City Library Portal was investigated. As a result of the survey, 24% of public libraries have a space for young adult, and if there is dedicated space, it was found that the most number of bookshelves for young adult were installed inside the space. Libraries that provide young adult services accounted for 76% of the total, and the age range of the service targets was set between 13 and 18 years of age. The analysis revealed that it was difficult to provide services due to a combination of problems such as poor use and passive participation by young adult, lack of dedicated space, lack of manpower for program operation, and lack of budget. Nevertheless, most librarians agreed on the need to provide young adult-only spaces and young adult services. The tasks to revitalize young adult services in public libraries was suggested; expand young adult participation in the space creation and service planning/operation stage, create a space dedicated to young adult, diversify the contents of youth volunteer activities, secure the professionalism of the librarian in charge, human resource utilization, and expand public relations for services.

  • This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.

  • This study make comparative analysis of the cataloging rules on the edition area included in the KCR4, NCR(2001), AACR2R, ISBD(M), and ISBD(ER). There is a delicate difference between the cataloging rules. The main features on the edition are as the follows. (1) In the bibliography description the concept of the edition is a general application. That is to say, the edition construct the new edition and the impression. The former comes the purview of a change content, the size, and a printing type. The latter publish newly- (2) The requisite for description of the edition area consists of a edition statement, statements of responsibility relating to the edition, additional edition statement, and statements of responsibility following an additional edition statement. Voluntary rules transcribe the parallel edition statement. (3) In the case of the electronic materials special versions on content and Auction indicates as the edition, but the environment of software does not indicate as it. (4) Parallel statement of responsibility relating to the edition, parallel additional edition statements, and parallel statements of responsibility following an additional edition statement are voluntary rules or not transcribed in the edition area.
