This study is to analyze the characteristics of 2019 revised RDA and suggest the consideration in aspects of cataloging using the literature reviews. The following 3 things are suggested with analyzing the revised RDA. First, high quality data such as supplementing cataloging data and constructing vocabulary encoding schemes should be needed to transform bibliographic data to linked data for the semantic web. Second, MARC should be expanded to accept the new conept of LRM and linked data being reflected in revised RDA because MARC is the unique encoding format untile linked data will be transformed from MARC data. Third, the policy statement and the application profile are needed for describing resource consistently because each entity and element has own condition and option, and there are different elements for applying rules in revised RDA. Based on this study, the RDA related researches should be in progress such as exapanding BIBFRAME as well as MARC to accept the new concepts in revised RDA, and, also, reflecting and accepting RDA being able to use revised RDA rules and registries in libraries and nations that have been faced to revise their own cataloging rules.

In Unicode, two types of Hangul encoding schemes are currently in use, namely, the "precomposed modern Hangul syllables" model and the "conjoining Hangul characters" model. The current Unicode Hangul conjoining rules allow a precomposed Hangul syllable to be a member of a syllable which includes conjoining Hangul characters; this has resulted in a number of different Hangul encoding implementations. This unfortunate problem stems from an incomplete understanding of the Hangul writing system when the normalization and encoding schemes were originally designed. In particular, the extended use of old Hangul was not taken into consideration. As a result, there are different ways to represent Hangul syllables, and this cause problem in the processing of Hangul text, for instance in searching, comparison and sorting functions. In this paper, we discuss the problems with the normalization of current Hangul encodings, and suggest a single efficient rule to correctly process the Hangul encoding in Unicode.

Web service implementations are now rapidly growing. Web services are easily achieved by XML messaging for most programming languages. Applications usually utilize web services through APIs tied to a specific implementation of SOAP. nML is a dialect of SML and OCaml made in ROPAS. The soaptype type in nML is defined for the value of SOAP encoding. SOAP encoding specification defines rules for serialization of a graph of typed objects using XML Schema. XML Schema validates XML SOAP value. The soaptype type is encoded to XML and decoded from XML. It is necessary to guarantee safe encoding and decoding. So, the definitions for element and type definition in XML Schema are specified by element type and typeinfo type, which include the part of the definitions of XML Schema specification.

This study examined and compared existing national library RFID data models, especially for Denmark, Finland, Netherlands, France, the U.S., Australia and South Korea. Four European country models(i.e., Danish, Finnish, Dutch, and French models) and South Korea use prescriptive data model(fixed encoding approach), while The U.S. and Australia adopt object-based data model, which is based on the data encoding rules of ISO/IEC 15962. This study expects to allow fertile ground for discussion on RFID data models in South Korean library environment.

In this paper, we discuss optimal design of Fuzzy Polynomial Neural Networks by means of Genetic Algorithms(GAs) using symbolic coding for non-linear data. One of the major subject of genetic algorithms is representation of chromosomes. The proposed model optimized by the means genetic algorithms which used symbolic code to represent chromosomes. The proposed gFPNN used a triangle and a Gaussian-like membership function in premise part of rules and design the consequent structure by constant and regression polynomial (linear, quadratic and modified quadratic) function between input and output variables. The performance of the proposed model is quantified through experimentation that exploits standard data already used in fuzzy modeling. These results reveal superiority of the proposed networks over the existing fuzzy and neural models.

In this paper, we present code-excited linear prediction coding using trellis coded vector excitation, termed trellis code-excited linear prediction coding (TCELP), for an efficient 8 kbps digital cellular vocoder. A training sequence-based algorithm is developed for designing an optimized codebook subject to the TCELP structure. Also, we discuss the encoding complexity of the TCELP system and trellis symbol release rules that avoid excessive encoding delay. finally, simulation results results for the TCELP coder are given at the bit rate of 8 kbps.

Syntax notation one (ASN.1) defined by ITU-T and ISO, is a formal abstrct specification language which has been widely used in international standards specifiation to inteconnect distributed open systems. It si necessary to have well defined encoder/decoder modules which taranslate ASN.1 datum to BER octets stream to interconnect distributed open systems. In this paper, we designed and implemented a new ASN.1-to-C compiler, called HYASNC (hanyang ASN.1-to-C), which atutomatically translates and ASN.1-to-C compiler, called HYASNC (hanyang ASN.1-to-C), which automatically translates an ASN.1 specification into C-language BER encoders and decoders with simple and neat I/F for the defined ASN.1 data types, and enhanced BER (basic encoding rules)encoding/decoding libraries, called HY(hanyang)BER library, and useful utility functions. And this paper discusses HYASNC compiler, HY BER runtime library's design and implementation principles, and also evaluates the perfomrance of HY BER library and the interoperability with other ASN.1 compilers.

In these days, compressed file is useful in internet environment and has many advantages. So a lot of data hiding algorithms works on JPEG compressed file. Of course they know basic rules of transformation and quantization and they utilize those rules to implement their programming. But most of them evaluate the affection of data hiding after data modification. We propose how to predict the affection of data modification in course of data hiding process. Through some kind of experiments, several valuable facts are revealed which used in data hiding in compressed domain such as JPEG. These facts will improve existing data hiding algorithms (F3, F4 and F5 which including Matrix Encoding)[1],[5],[6].

The software for unmanned control of three row typed rice combine has been developed using fuzzy logic. Three fuzzy variables were used : operating status of combine, steering, and speed. Eleven fuzzy rules were constructed and the eleven linguistic variables were used for the fuzzy rules. Six sensors were use of to get input values and sensor input values were quantified into 11 levels. The fuzzy output was infered with fuzzy inferrence which uses the correlation product encoding , and it must have been defuzzified by the method of center of gravity to use it for the control. The result of performance test using graphic simulation showed that the intelligently unmanned control of a rice combine was possible using fuzzy logic control.

Fuzzy controllers also show good performance In case of the systems being nonlinear and difficult to solve. But these fuzzy controllers have problems which have to decide suitable rules and membership functions. In general we decide those using the heuristic methods or the experience of experts. Therefore, many researchers have applied genetic algorithms to make fuzzy rule automatically. In this paper, we suggest a new coding method and a new crossover method to maintain the good fuzzy rule base and the shape of membership
