The discoloration of traditional paintings could be induced by various chemical reactions of inorganic pigments due to temperature, humidity, light and air pollution. In this study, we made artificial samples including azurite and malachite as inorganic pigments using the traditional method on hanji called 'Korean paper'and investigated the artificial aging process occurred by the interaction between pigments and environmental factors. It was found that the azurite was influenced by the humidity of weathering tests and the salt fog of salt spray tests according to XRD and TGA results. However, it was shown that the malachite was chemically changed by the ultraviolet radiation of weathering tests and UV radiation tests according to color difference and TGA results.

The emotion and culture of an age are reflected through several mediums. The special quality and generality are discovered through household utensils used in everyday life specially. This paper was intended as proceeding study for brand development with national empathic relationship. In this article, we were here concerned with symbolism and features for stories of traditional pattern on ancestral common household utensils, and considered about development possibility by brand of tradition pattern. As analysis for symbolism of traditional pattern, re-sorting and classifying pattern, meaning, symbol and stories of pattern based on 'Blessing notion' were set. It was found from the analysis that meaning and symbol of traditional pattern were set up and stories for them were excerpted. This study defines tradition pattern classified based on 'Blessing notion' as '8 Blessing pattern', and investigated development possibility and derivative value of it. We discovered through this study that 'Blessing patterns' function as communicator, have 4 abilities in sympathy with brand paradigm, and have 6 elements of brand identity. Furthermore, 'Blessing Patierns' have some derivative functions; cognitive intension, expression, loyalty, differentiation and symbol. This research will become basis of study for brand development having 'Empathic relationship' and foundation of 'Blessing brand' that is available to be umbrella and super brand. A further direction of this study will be to make 'Blessing brand series' and to create culture of it. We hope Korean brand market goes a step further through our studies

Gold threads mean thread made by metal, it is composed various material to gold leaf, adhesive and media. The making technique and using materials of Gold threads are different from region, it can be used to distinguish country of origin. So this study finds characteristics and making techniques for flat gold threads of relics. Standard samples are made of animal glue, lacquer, red lacquer and etc. This materials are based on the scientific investigation of cultural gold threads properties. Then traditional techniques were estimated by comparison and analysis of actual cultural properties and standard samples. As a result of investigating cultural properties, it is similar to the standard sample which are mixed with red soil additives. After analysis of SEM-EDS, it is detected to Al, Si, Fe. So it is to the conclusion that traditional gold thread is made of adhesive mixed with red soil to improve gold color better. And this ways are similar with china that uses animal glue and red soil to adhesive and different from japan that uses lacquer to adhesive. Through this study, it will be used to data and reference for reappearance and making techniques of traditional gold threads.

The aim of this study is to discover the possibility as the shading systems, and to analyze daylight distribution and characteristic of light on the Korean traditional paper. Korean traditional paper has a good efficiency to diffuse the light and is less glare than Roller Shade fabric. In the president office buildings and apartment houses, daylight characteristic of Korean traditional paper windows could be used as a preliminary data to develop a window system which makes greatest performance of daylight.

RDB나 기존의 ISAM 파일이 검색과 저장의 효율성이 높을지라도 다양한 형태의 자료 저장 능력과 프로그래밍의 효율성 부족에 대한 대안으로 객체지향 프로그래밍과 객체 지향 DB의 활용이 확대되고 있는데 1996년, 미국의 경우 활용기업의 비율이 15%정도에 이르며 증가추세에 있는 것으로 나타났다. 본 연구는 OOP, OODB를 EDP 감사의 관점에서 연구하는 것으로 전통적 EDP 감사도구와 기법을 객체지향모형에 적용가능한지와 적용시에 예상되는 문제점을 검토하려는 것이다. 주요한 EDP 감사도구와 기법중 입출력에 초점을 두 는 Test Data, Integrated Test Data/Facility에는 적용이 비교적 쉽지만 처리과정에 초점을 두는 Embeded Audit Module, GAS 등에는 구현을 위한 메소드의 수정이나 설치상의 문제 가 큰 것으로 보인다. 그러므로 GAS를 구현할 때 감사모듈을 설치하는 절충법이 필요한 것 으로 보인다.

본 논문은 데이터의 군집화를 효율적으로 수행하기 위하여 새로운 군집화 알고리즘을 제안한다. 제안되는 군집화 알고리즘은 Fuzzy C-Means (FCM)에 기반을 두는데, FCM 알고리즘은 모든 데이터에 대한 거리에 기본을 둔 멤버쉽을 기초로 하기 때문에 잡음에 약한 제약을 지니고 있었다. 이를 개선하기 위하여, 제안되었던 PCM(Probabilistic C-Means), FPCM(Fuzzy PCM), PFCM(Probabilistic FCM) 등 여러가지 알고리즘이 제안 되었다. 그러나 이들 알고리즘들은 초기 파라미터값 설정과 과다한 계산양에 따른 문제가 증가하였으며, 또한 잡음에 어느 정도 민감한 문제점을 지니고 있었다. 이 논문에서는 잡음에 대해 효과적으로 대응할 수 있는 새로운 군집화 알고리즘을 제안하고, 전통적인 군집화를 위한 Iris 데이터에 대한 실험을 통하여 효용성을 확인하였다.

본 연구는 과학기술 대중화가 왜 중요한지에 대한 문제인식에서 시작되었다. 즉 과학기술이 발전하기 위해서는 일반국민의 이해와 참여가 있어야 가능하다. 또한 과학기술에 대한 대중적 이해가 없이는 과학기술 자체에 대한 대중적 지지를 획득하기 어렵다는 점이다. 이에따라 과학기술에 대한 일반국민의 이해를 제고시킬 수 있는 방안들을 모색해 보았다. 먼저 과학기술 선진국인 미국의 경우, 과학기술 대중화를 위한 과학언론 전문가 집단의 역할과 과학언론매체의 영향이 매우 지대하였음을 살펴보았다. 그러나 미국의 20세기 과학기술 대중화운동은 이들의 역할에 주로 의존한 나머지 본래의 과학적 사실이 담고 있는 상황을 일반대중에게 제대로 전달하지 못하는 역기능이 발생한 점도 간과할 수 없다. 아무튼 미국은 전통적으로 과학기술을 국가발전의 근간으로 여겨 과학언론매체의 개발과 함께 과학언론 전문가를 양성하여 일반대중이 과학기술이 무엇인지 이해하는데 크게 기여하였다. 이에반해 우리나라는 전문인력부족, 언론매체의 인식미흡, 대중화사업의 중복 및 유사성 등 과학기술에 대한 일반대중의 이해와 참여를 이끌어 내기에는 한계를 지니고 있다. 따라서 한국의 과학기술 대중화를 위해서는 홍보전문인 육성, 정보전달매체의 다양화, 과학대중화 사업 등이 상호 유기적이며 보완적인 관계로 발전해 나가야 할 것이다.

The inorganic compositions of traditional lye, and lyes prepared from the stalks of five different agricultural products: beans, wheat, barley, buckwheat and red peppers, were analyzed. Traditional lye was composed mainly of a weak alkaline salt, potassium carbonate as the major component and neutral salts, potassium chloride and potassium sulfate as minor components. The ash and lye contents of buckwheat have significantly higher then those of the rest agricultgural products. Bean and red pepper stalks lyes were composed mainly of potassium carbonate, similar to the composition of traditional lye, but also contained potassium chloride or sulfate. In contrast, postassium chloride was the major component of wheat and barley stalk lye.

The purpose of this study is to clarify the historical background of the setting of seungdang(僧堂) and gowon (庫院) in the Zen Buddhist temples of Song dynasty, in terms of as a Buddhist temple universality and as a Zen temple specificity, through the historical reference investigation on its relevance to the Buddhist temples of Tang dynasty. In the Zen Buddhist temples of Song dynasty, the Zen meditation space of seungdang was located on the west side of Buddha hall, and the kitchen and officiating priest's living space of gowon was located on the east side of Buddha hall. Through the analysis of historical reference it was confirmed that, in the Buddhist temples of Tang dynasty, the Zen meditation section of seonwon(禪院) was on the west side, and the gowon was on the east side too. Therefore, it can be said that, the setting method of seungdang and gowon of the Zen Buddhist temples of Song dynasty was established above tradition of the Tang dynasty Buddhist temples.

The purpose of this study is to analyze daylight distribution and light characteristics on the Ma-ji and Roller Shade fabric, and to investigate a possibility of using it as a shading system. Using a 1/2 Mock-up model, daylight distribution is analyzed with the Ma-ji and Sun-ji (Korean traditional paper) which have good efficiency and less glare. Ma-ji has the best daylight distribution, so that daylight experiment is conducted with the Ma-ji and Roller Shade fabric. In current office buildings and apartment houses, daylight characteristics of Korean traditional paper windows could be used as preliminary data to develop a window system which makes better daylight performance.
