Gi(氣) transformation theory is the foundation of Traditional Chinese Medicine[TCM]. This theory matured during the period of "Hwangjenaegyeong(黃帝內經)", and later in the history of TCM was a source of significant impact on the development process and direction of general medical theory. The concept of "gi transformation[氣化]" mainly originates from the definition of the three levels which are nature, the relationship between nature and human, and the body's own metabolism, and is used to describe the usage and the resulting changes of 'gi(氣)'. Gi transformation possesses six characteristics which are permanence, universality, representationalism, directional, variability, and orderliness. The research of the concept and characteristics of gi transformation[氣化] in "Hwangjenaegyeong" will help identify the important academic value and practical significance of the formation of the basic theory of TCM as the result of the gi transformation theory, and highlight the unique characteristics of TCM.

The Korean Phonetic Alphabet(KPA) as devised by H. B. Lee on the basis of Han-geul, the Korean Alphabet, was incorporated into the Hangul Word Processor(HWP) 1. $^{*}$ to be used on personal computers. With the upgrading of the HWP software from $1.^{*}$ to more sophisticated versions of $2.^{*}$, $3.^{*}$, etc., it became necessary to convert the HWP $1.^{*}$ KPA into upgraded version. This paper traces the history of the computerized KPA software from the initial version of HWP $1.^{*}$ to the latest one.

Recently the blockchain technology has been actively studied due to its great potentiality. The smart contract is a key mechanism of the blockchain system. Due to the short history of the smart contract, many issues have not been solved yet. One main issue is vulnerability and another main issue is cost optimization. While the vulnerability of smart contract has been actively studied, the cost optimization has been rarely studied. In this paper, we propose two cost optimization methods for smart contracts running on the blockchain system. Triggering a function in a smart contract program code may require costs and it is repeated continuously. So the minimization of costs required to trigger a function of smart contract while maintaining the performance equally is very important. The proposed two methods minimize the usage of expensive permanent variables deployed on the blockchain system. We apply the proposed two methods to three prevalent blockchain platforms: Ethereum, Klaytn and Tron. Evaluation experiments verify that the proposed scheme significantly reduces the costs of functions in the smart contract written with Solidity.

Integration systems help users consume services more effectively. However, previous integration systems can only enable predefined service cooperation to satisfy users, which is difficult to achieve user-centric service composition in dynamic environments. Therefore, in this paper, a dynamic service integration system is proposed to automatically combine services based on usage history. With this system, services can be dynamically composed to meet users' needs and information can be flexibly transited among heterogeneous services.

Research papers must be expression given by letter that had fixed types, rules and universal sentence languages to inform many persons about study results until present when these research paper was considered review, oriental medical papers had some problems, as like difficult contents not to inform absolutely, usage of past language, not considerable in logic history and continuity, and have used not fixed types and rules, error of statistical analysis and research construction. Also centered clinic that had trends important treat tools by drugs ,acupuncture and moxa studies. In briefly, papers of korea traditional medicine had some several problems. Oriental medicine has very concerns not only korean but other countries in present and then it will increases much more study in future. For the purpose cope with this concerns korea traditional medicine researchers need much educations of relation department and must recognized much concerns.

The exhaust system of automobile is faced with random or spectrum types of fatigue loads during usage life and so needs to be closely estimated for quality and performance to have enough certainty on design endurance lift during preliminary design process. Structural operation conditions, operation load history, property of material and manufacturing process etc. should be considered by performing experiment approach. Using the software program for predicting fatigue life quickly and exactly in preliminary design stage saves plenty of time and cost generated by fatigue tests. In this paper, fatigue life prediction was performed on the basis of fatigue analysis using MSC/FATIGUE and load data from field test and the life of development items was estimated and compared through the results.

As the information society appears, the increasing power and access of personal computers along with wide spread use of the information technology has not only changed the landscape for communication but it has opened up new and exciting opportunities for education. One of the ways that information technology could help improve education is to be used in interactive communication to share the knowledge and experience of all the teachers as well as students. In this paper, the use and application of information communication technology[ICT] into mathematics classroom are described and showed several examples. furthermore, the web site design and developed for this study was introduced of the purpose of sharing the ideas about the knowledge and usage of the history of mathematics and examples of mathematical connections. The study suggests that enabling mathematics in incorporating of ICT by teachers and students requires more effort to be made in training teachers on the use and application of ICT into mathematics classroom.

All technology has both intended and unintended effects, we have said, and information technology is no exception. Information technology offers a number of challenges: those of computer education, computer literacy, the ethical and societal impacts of computing and communication systems. Current computer education focuses primarily on the history, parts and usage of a computer, and programming, it does not fully include the moral standards or ethics that help guide behavior and conduct for citizens of Information society. The purpose of this study is to review of the theoretical issues and societal impacts of computers, communication systems and computer ethics; then, to nalyse current curriculum and content of school computer education in Korea: finally, to develop a possible course in computer ethics containing a goal statement and aspects of computer literacy. Contents in computer ethics covers issues of nettiquette, privacy, health, copyright-related software and network piracy, computer crime and viruses. Six suggestions are made for the computer ethics of Information Age in the conclusion.

The purpose of this research was to understand changes in Korean shrouds and to enhance practical usage of them by examing the items and shapes of Korean shrouds classified into two categories, traditional and current. We first examined the history of shrouds and funeral ceremonies from the prehistoric age to the Chos o n dynasty, and second, examined the items and shapes of traditional and current shrouds. As for the items, no big changes were recognized though there had been some changes in the way of using Keum(衾), Po(袍), and Kwadu(裏　). Overall, the items had becamesomewhat simplified The traditional shapes of shrouds are relatively well-maintained despite some changes in current shrouds Aksu, Yeomo(女帽), etc, which had been made easier to put on.

Natural indigo dyeing has been used mainly on cellulosic fibers and silk during the course of history in Korea. In order to extend the usage of this one of the most important natural dyes, its dyeability on wool fabrics has been studied to find out the optimum dyeing condition for wool fiber which is susceptible to alkaline medium. The dyeing method used was hydrosulphite vat of extracted dye. K/S values of dyed fabrics were investigated to analyze the dyeability of natural indigo on wool fibers and colors were measured through $L^*,\;a^*,\;b^*$ and Munsell Values. Highest K/S values were obtained at the temperature of 60(C and pH 7 to 8. The Munsell Values for hue of wool fabrics dyed with extracted indigo powder using hydrosulphite vat fell mostly in PB range. As the dyebath pH increased, blueness increased. Different dyeing conditions resulted in change of colors of dyed fabrics due to the difference in amounts of indigotin and indirubin contents within the dyed fiber as shown by HPLC.
