This paper presents a concept of cellular automata and a modular exponentiation algorithm and implementation of a basic EIGamal encryption by using cellular automata. Nowadays most of modular exponentiation algorithms are implemented by a linear feedback shift register(LFSR), but its structure has disadvantage which is difficult to implement an operation scheme when the basis is changed frequently The proposed algorithm based on a cellular automata in this paper can overcome this shortcomings, and can be effectively applied to the modular exponentiation algorithm by using the characteristic of the parallelism and flexibility of cellular automata. We also propose a new fast multiplier algorithm using the normal basis representation. A new multiplier algorithm based on normal basis is quite fast than the conventional algorithms using standard basis. This application is also applicable to construct operational structures such as multiplication, exponentiation and inversion algorithm for EIGamal cryptosystem.

In this paper, a best-basis selection algorithm that improves the performance of the coding gains and the computational complexity is proposed. The proposed algorithm limits the computational complexity according to the resolved threshold value and decomposes the parent subbands by using the top-down tree search and the relative energy between the parent subbands and the child subbands. For the experiments of the proposed algorithm, the bit-rates, the peak signal-to-noise ratio (PSNR), and the reconstructed images are presented by using the Quad-tree coder. The result of the proposed algorithm is compared to that of DWT algorithm using the Quad-tree coder for a set of standard test images. In addition, the result of the proposed algorithm is compared to that of JPEG-2000 algorithm and that of S+P algorithm.

On the basis of the review of radiobiological date, a formalism is developed for the analysis and prediction of iso-effect relations for tissue tolerance, which can be used as an alternative to the norminal standard dose(NSD) formaula of Ellis and its derived equations. An important feature of the described formalism is that directly based on radiobiological insights and it provides a more logical concept to account for the diversity of tissue responses. The NSD concept has subsequently been extended to the formalisms of timedose-fractionation(TDF) value. The authors deriveded TDF equation on the basis NSD of Ellis. TDF=0.07(NSD)-26.

This paper describes fuzzy radial basis function networks(FRBFN) extracting fuzzy rules through the learning from training data set. The proposed FRBFN is derived from the functional equivalence between RBF networks and fuzzy inference systems. The FRBFN learn by assigning new fuzzy rules and updating the parameters of existing fuzzy rules. The parameters of the FRBFN are adjusted using the standard LMS algorithm. The performance of the FRBFN is illustrated with function approximation and system identification.

Many presentations of documents are rejected because credits have been incorrectly issued. One reason of rejecting the documents is related with error in application stage of L/C. Errors may take the form of mismatches between the terms of the sales contract and the provisions stipulated in the credit. Thus, Article 5 encourages applicants to make their contribution to the smooth running of the letter of credit process by being unambiguous and brief. Another reason that the banks reject the documents relates to the ambiguity of the term "International Standard Banking Practice" That is to say, UCP500 Art.13 introduced the term "International Standard Banking Practice"(ISBP) without the definition so that one wonder what ISBP is or how ISBP apply in daily work of bankers, examination of documents. From hence, International Chamber of Commerce(ICC) started the work to document ISBP at May 2000, finally approved the result last year and published the publication titled "International Standard Banking Practice for the examination of documents under documentary credits." By applying ISBP in document examination stage, I expect that the freqency of rejecting the documents grow less and bankers' work of examination become easy. On the other hand, ISBP is supplement to UCP500 so that the interpretation of ISBP is made on the basis of understanding of UCP and its underlying principles. So, I reviewed each paragraphs of ISBP on this basis and tried to indicate contradiction between ISBP and UCP500. But because of reading not enough, I failed to search the connotative sense many paragraphs have.

UCP 500 has introduced new words "International Standard Banking Practice" as the basis of the examination of documents under documentary credits. However, the words have caused confusion among parties concerned with letter of credits. So, at its May 2000 meeting, ICC Banking Commission established a task force to document international standard banking practice for the examination of documents presented under documentary credits(ISBP). The publication is the product of two and a half years of work by a task force of the ICC Banking Commission. It was approved by the full Commission at its meeting in Rome in October 2002. The ISBP is a practical complement to UCP 500. It explains how the rules are to be applied on a day-to-day basis. As such, it fills a needed gap between the general principles announced in the rules and the daily work of the documentary credit practitioner. But, ISBP have two problems. First, ISBP impose more responsibilities than before the ISBP existed on banks. Second, ISBP have some problematic articles like the problem of maturity, letter of credit language, term. Consequently, all parties concerned with documentary credits need to armour themselves with knowledge for ISBP. Also, it should be noted that any term in a documentary credit which modifies or affects the applicability of a provision of the UCP may also have an impact on international standard banking practice. Therefore, in considering the practices described in this publication, parties must take into account any term in a documentary credit that expressly excludes or modifies a provision in an article of the UCP.

The purpose of this study is to provide the improvement basis for Dental Hygiene education program by analyzing the current implement status of Dental Hygiene curriculum in Korea and comparing the status with the US ADA standard. The researcher analyzed the Dental Hygiene syllabus limiting "Dental prophxis", "Comprehensive dental hygiene" subjects only from 31 universities which offer 3 years program. The main interest was to figure the implementing status of the curriculum and to compare the actual teaching content with the CODA 2-17 standard. The results show that there are a number of problems in implementing the Dental Hygiene courses among different universities. First, there is a significant inconsistence among schools in terms of course title, total credit, hours, the ratio for theory and practice, etc. In addition, there is a big gap between the actual content of Dental Hygiene courses and the essential/required content of CODA 2-17 standard. For instance, most of the Dental Hygiene programs in Korea cover the overall assessment stage content and some of implementation stage content. However, very few programs deal with the planning and evaluation stage content. To improve these problematic circumstance a number of suggestions were made. Developing the standardized curriculum for the Dental Hygiene program might be one of the major solutions. Next, the regular accreditation and/or assessment system for the Dental Hygiene program should be developed. This research can provide the basis for the need to assess and improve the Dental Hygiene curriculum.

This study was conducted to evaluated the nutrition quality of the commercial supplementary foods for infants and young children and to seek a solution to the establishment of standards of nutrient requirements for supplementary foods in Korea. Information on food ingredients, nutrient contents, claims about usefulness of food components and instructions for feeding preparation were obtained from the labels of 33 commercial supplementary foods manufactured by 4 different domestic companies. According to the standard of supplementary foods for infants and young children described in the Korean Food Code, the commercial supplementary foods were categorized into two different types, weaning food and baby food. All the commercial weaning foods were in powder form and mainly composed of cereals, whereas all the baby foods were mainly composed of fruits in the form of canned juice. The weaning foods contained more nutrients than the baby foods did, and the nutrient levels of the weaning foods expressed as nutrient density on energy basis were higher than the RDA for infants aged 5 to 11 months, suggesting that the commercial weaning foods provide adequate amounts of nutrients. If one followed the instructions for feeding preparation appearing on the label, however, recommended amounts of intake of the weaning foods would provide too much energy as well as nutrients. There were many differences in nutrient standards of weaning foods between the Korean Food Code and Codex international food standard. In conclusion, the establishment of standards for nutrient requirements for the supplementary foods requires significant scientific studies on what nutrients are the most inadequate in Korean infants and young children feeds and what levels of nutrients should be added to the foods in order to supplement their nutrition. In addition, it is very important to have a strong scientific basis to support our standard when discrepancies exist between our standard and the international standard.

Following the 2011 Fukushima Nuclear Power Plant accident, the IAEA has issued a revised version of the Nuclear Safety Standard for beyond design basis earthquake to consider the core meltdown accident. In Korea, relevant laws and regulations were also revised to consider beyond design basis earthquake to nuclear components. In this paper, CAV, an seismic damage factor that determines the restart of nuclear power plant after operating breakdown earthquake, is proposed for extension to the beyond design basis earthquake. For pipings not satisfying the beyond design basis earthquake condition, several evaluation methods are suggested, such as strain-based evaluation methods, simple nonlinear analysis method and cumulative damage evaluation method.
