The aim of this study is to propose a development plan of public library OPAC interface. For this purpose, the study analyzed cases of OPAC interface of domestic and overseas public libraries, and took a questionnaire survey on use types, level of functional demand and improvement matters of OPAC in order to examine the user requirements on OPAC interface. Public library OPAC interface must comply with interface design principle and reflect requirements of users. Accordingly, it must supply foundation to realize various OPAC functions by inputting perfect bibliographic records on resources. The research result could be used as basic resources for the public library OPAC interface design.

In the last decade, nuclear medicine appears to be a good choice of medicine. ⁵⁸Co, ⁹⁹Mo, ⁹⁹Tc, ⁹⁹Re, ¹³³Xe and ¹⁸⁶Re are very important radionuclides for nuclear medicine. In this study, the excitation functions of ⁵⁸Ni (n, p) ⁵⁸Co, ⁹⁹Tc (n, p) ⁹⁹Mo, ⁹⁹Ru (n, p) ⁹⁹Tc, ¹³¹Xe (n, p) ¹³¹I, ¹³³Cs (n, p) ¹³³Xe and ¹⁸⁶Os (n, p) ¹⁸⁶Re nuclear reactions were calculated at neutron energies between 1 and 20 MeV using TALYS 1.95 and EMPIRE 3.2 nuclear codes. Furthermore, the cross sections were calculated with the empirical formula derived in our past study at 14-15 MeV. The obtained results were compared with the measured values in EXFOR library, and with the evaluated data of (JENDL-4.0/HE, JEFF-3.3, TENDL-2019, ENDF/B-VIII.0, IRDFF-II, JENDL/ImPACT-18). The results are in good agreement with those of the evaluated data libraries and experimental results and indicates that these radioisotopes can be produced by smaller cyclotrons.

Open education is a worldwide movement to overcome educational barriers based on digital technology. It is necessary to discuss how to carry out the educational function of the library in the increasingly widespread open education environment. This study examines the concept and components of open education, and proposes an approach to how the library performs educational functions in an open education environment. The results of this study will serve as a guide in setting the role and direction for the library to become the subject of the implementation and spread of open education from the perspective of the library's educational function.

The rapid change in almost every area of science at the turn of the 21st century have also affected libraries and information centers. Whatever the change, from the library users' perspective, the functions provided by the library, is perceived as "service" and the satisfaction of the users can only be measured by the quality of the service. The library and information center acting as a service provider aims to establish a framework for improvements in services by focusing on the user's perspective on service quality and classifying the factors that contribute to service quality. This study adopted the LibQUAL+ model, which is derived from SERVQUAL model for measuring quality of service in the field of Service Marketing.

This paper presents the implementation of libraries of hardware modules for genetic algorithm using VHDL. Evolvable hardware refers to hardware that can change its architecture and behavior dynamically and autonomously by interacting with its environment. So, it is especially suited to applications where no hardware specifications can be given in advance. Evolvable hardware is based on the idea of combining reconfigurable hardware device with evolutionary computation, such as genetic algorithm. Because of parallel, no function call overhead and pipelining, a hardware genetic algorithm give speedup over a software genetic algorithm. This paper suggests the hardware genetic algorithm for evolvable embedded system chip. That includes simulation results and analysis for several fitness functions. It can be seen that our design works well for the three examples.

This paper summarizes a development of visualization software for protective engineering in low-voltage power systems. The study is concentrated on the following aspects. First, a software engineering method is applied for designing the object-oriented program. The design and implementation of a Graphic User Interface(GUI) and its integration to a power system framework are developed using object-oriented programming(OOP) in Visual C++. Second, we develop the short circuit analysis module that oriented a low-voltage power system. It is possible to calculate a peak, symmetrical RMS, DC component and asymmetrical fault currents for each time. And it is the first software that can calculate the fault current for single branch of three-phase system. The calculation accuracy is compared with commercial software, and the libraries of low-voltage components are served for convenience use. Third, protective engineering functions are equipped. It is possible to automatically select the circuit breaker which based on the user input characteristics and the fault current calculation and examine the protective coordination. Through the case study, we verified that the developed software can be effectively used to examine the protective engineering in low-voltage power systems.

In this research, we developed a design system for a compressor of an air conditioner using solid CAD system. The developed design system has some characteristics. First, the design system used a configuration design method, so a designer can design a compressor very quickly by using the constructed master libraries. Next, the system was developed to be used not only by engineers but also by salesmen. It is very easy for a user to use it, so a salesman can get a result very easily with the design system. And it has some design modules which give a considerable convenience to designers. Actually, designers are accustomed to the module based design. Then, it has calculation and analysis functions. Volume and mass of a part, and interference between parts are calculated by using the geometric calculation function of a solid CAD system. Also a packaging calculation was implemented to get the smallest space to package compressors for transportation and storing. An interface with a program to analyze the vibration of a compressor was developed in this design system. The design system is similar to CBD (Case-Based Design) system in the view of the whole design process.

This paper describes the development of the interactive hullform transformation program. This program has many hull transformation functions such as main particular transformation, deadrise generation, section characteristic transformation, local transformation and CB, LCB variation, etc. MBASTRANS adopted the GUI(Graphical User Interface) using the OSF/Motif based on the X-Window system and used X-PLOT and GLBAX which are 2 and 3 dimensional graphic libraries, respectively. The interface module cans generate the information of the hullform for the SIKOB package and the hydrodynamic analysis.

Since information technology such as database or network technology was brought into the information and library science fields, the functions and services of libraries have drastically changed. To cope with the changes of fields, library schools have been improving curricula. This study collected curricula of library and information science in US and Korea and selected classes related to information technology. It also investigated the title keywords and keywords of class description statistically. As a result, 'system, 'database', 'network', 'programing', 'web' are major topic keywords for both countries, but 'library'shows high frequency pnly in Korea.

Code reuse in software reuse has several limitations such as difficulties of understanding and retrieval of the reuse code written by other developers. To overcome these problems, it should be possible to reuse the analysis/design information than source code itself. Therefore, this paper present analogical matching techniques for the reuse of object models and patterns. And this paper have suggested the object model and the design patterns as reusable components and the representation techniques to store them. Namely, the contents of the paper are as follows. Analogical matching functions to retrieve analogous components from reusable libraries. And the representation of reusable components to be stored in the library in order to support the analogical matching.
