Because of the result of a large use of electronic equipments, the occupation density of microwave frequency band is highly increased, and electromagnetic environment is getting more seriously bad. It is sometimes reported that electronic machines are not normally operated on account of the influence of undesired electromagnetic wave, which often gives fatal blow to even human life and thus becomes serious social problems. OATS(Open Area Test Site) is principally used to measure EMI or examine elelctromagnetic emission. Because of various restrictions we often build semi-anechoic chamber which has the function of OATS to measure EMI or EMS other than OATS. If the difference of the site attenuation between semi-anechoic chamber and OATS is within ${\pm}3dB$, the semi-anechoic chamber is recognized as adequate facility to measure EMI or EMS. Accordingly authors evaluate and analyze site attenuation due to absorbent materials, polarization, mutual coupling effects, etc. The calculated and the measured site attenuation in semi-anechoic chamber are compared. As a result good agreement is obtained.

In this study, a user-friendly expert system is developed for bright nickel plating processes which have a number of influence factors related to the plating quality. Because the mutual relations between these factors in the processes are not quantitatively identified, the expert system deals mainly with the troubleshooting process problems by using the production rule which is able to utilize effectively the qualitatives knowledge and the accumulated experience. Especially, to provide the system user with more timely and convenient informations about the cause of problem symptom and the corresponding countermeasure, it is introduced the interactive user interface using the Korean language. Also the knowledge base and inference engine of the expert system are completely separated, so that the substance of knowledge base can be easily updated and extended.

본 연구는 서로 다른 문화간에 e-Learning과 같은 학습 시스템을 제공할 때, 학습 제공자의 문화적 차이에 의한 비언어적 행동이 학습자에게 미치는 영향에 대해 다루고 있다. 지금까지 사회언어학적인 관점에서 서로 다른 문화간의 언어행동에 관한 연구는 있었지만 비디오 학습이나 웹과 같이 원거리에서 이루어지는 학습 지원 시스템에서의 언어행동에 관한 연구는 없었다. 본 연구에서는 행동언어학적인 관점에서 이루어진 연구를 바탕으로, 한국인과 일본인을 대상으로 하여 실제 강의가 이루어지는 동안 언어행동의 문화적 차이가 미치는 영향과 그 결과를 검증했다.

The spectral correction matrix has been established to study the simultaneous complextions between metals and a ligand, and it eliminated the mutual influence among the complexes. The two sensitive reations between iron(Ⅱ) and 1-(6-bromo-2-benzothiazolylazo)-2-naphthol(BBTAN) and zinc (Ⅱ) and BBTAN have been investigated and applied to the simultaneous determination of Zn and Fe at pH 8.5 in the presence of triton x-100. This method gave the simples determination of the characteristic constants of the complexes. For the analysis of natural water, foods and other samoles, the recoveries of Fe and Zn were between 92 and 109% and between 91 and 104%, and their relative standard deviations were less than 5.5 and 11%, respectively.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. This Single PPM Quality Innovation Movement program was conducted to realize the anticipated results not only due to management result level's increasing, but also the company's confidence and competitiveness. This study attempted to find the mutual influences on the participation of the constituent members, satisfaction of the constituent members and results of the management from Single PPM Quality Innovation Movement. The reliance analysis for the measurement material on the questionnaire was verified by Cronbach's alpha coefficient. Participation of the constituent members, satisfaction of the constituent member and result of the management, the influences upon Single PPM improvement degree level were verified through the structural analysis by using SPSS statistic package. The influence evaluation among the groups was evaluated by the structure equation.

The aim of this article is to describe direction of Sino-Russian relations toward a new epoch - as the decision-making centers of both countries define them - indicating the commitment to building the future international order. It includes the synthesis of evolution of relations, descriptions of cooperation building of mutual confidence by both sides in variety of institutions; analyses of geo-economic relations emphasizing their geostrategic dimension and finally dynamics showing how two great powers want to achieve new areas of cooperation focused on building multipolar world order which is the essence of "new epoch". The argument goes towards recognizing the relationship as a "hhybrid alliance". This hybridity is a structural factor that can constrain the use of new dimensions of asymmetric interdependence as political leverage especially by United States against the two non-western powers but also facilitate to use it against West.

This study was based on the analysis of changes in curriculum of elementary mathematics curriculum, and changes in curriculum of middle school and high school mathematics curriculum. The purpose of this study is to analyze the movement of learning contents among the school levels based on the middle school mathematics curriculum and to summarize the influence on the curriculum of middle school mathematics according to the movement of learning contents. The research conducted according to the purpose of this study is as follows. First, we analyzed the trends of mathematical contents between elementary and middle schools after the movement of ten mathematics curriculums. Second, we analyzed trends of learning factors after mobility and mobility between middle school and high school. Third, the characteristics of 'the contents of mutual movement based on middle school' and 'the contents deleted from middle school' were analyzed. The results of this study are expected to reflect on current and past curriculum and to give meaningful implications to the composition of new curriculum.

The purpose of this study was to analyze the arrangement of rooms in Park Gil-ryong's housing plans to understand the influence of ondol on his design. Architect Park published diverse housing plans in Korean newspapers and magazines. Out of them, this study attempts to select the urban housing for the middle class as an object of analysis, and clarify the mutual relationship between the ondol and their room arrangement. This study is significant because it gives a precious opportunity to understand Park's ideas on housing improvement in the 1930s, and how his ideas affected other architects.

Chinese figure painting is the earliest type of painting to be mature in the history of Chinese painting. After its peak in the Jin and Tang dynasties, Chinese figure painting turned into a low tide in the Ming and Qing dynasties. Under the influence of the May Fourth New Culture Movement's concept of "introducing the Western culture into China", realistic ink wash figure painting emerged, which was different from traditional painting. Realistic ink wash figure painting is a new kind of painting that combines traditional Chinese painting methods with concepts of Western scientific painting. With the mutual reconciliation of realistic modeling and traditional Chinese painting, it makes up for the shortcomings of traditional Chinese figure painting in reproducing life, thus forming the diversified development of Chinese figure painting. Through an in-depth interpretation of the fusion of Chinese realistic ink figure painting with Chinese and Western, this paper accurately grasps the characteristics of the painting language, which is an important guide to the creation of Chinese realistic ink painting today.

This study constructed a VAR model with cotton futures and spot price data from April 30, 2009 to November 16, 2022, for empirical analysis utilizing the Granger causality test to analyze the dynamic relationship between cotton futures and spot market prices in China. The impulse response function and variance decomposition analysis showed that the cotton spot prices at flowering have a causal relationship with each other; in terms of mutual influence and impact, futures prices are higher than spot prices. Finally, it proposed countermeasures and suggestions from the perspective of establishing a standardized cotton spot market, improving the laws and regulations of the cotton futures market and trading system, and optimizing the structure of investment subjects.
