인터넷의 발달과 네트워크의 발달로 인하여 디지털 데이터에 대한 저작권 문제가 발생하고 있다. 최근 디지털 데이터에 대한 문제점을 해결하기 위한 방법으로 디지털 워터마킹에 대한 연구가 많이 이루어지고 있다. 본 논문에서는 디지털 데이터의 무단 복제와 배포를 박기 위해 웨이브렛을 이용한 주파수 변환을 이용하고, 워터마크로 디지털 지문을 삽입하였다. 웨이브렛 변환 영역중에 HL영역에 워터마크가 가시성과 추출 결과에 좋은 결과가 있었다.

1. Objectives This study is purposed to classify deficiency syndrome(虛證) and Excess syndrome(實證) of chief lung-disorder diseases. 2. Methods It was researched on the comparative and literal study about the relation to Yeong-Chu Gyeong-maek Chapter (${\ulcorner}$靈樞 經脈編${\Ircorner}$) and Dongui-Bogam (${\ulcorner}$東醫寶鑑${\Ircorner}$) and Dongui-Susebowon (${\ulcorner}$東醫壽世保元${\Ircorner}$) in chief lung-disorder symptoms or diseases. 3. Results and Conclusions (1) The chief lung-disorder diseases of Yeong-Chu Gyeong-maek Chapter (${\ulcorner}$靈樞 經脈編${\Ircorner}$), Dongui-Bogam (${\ulcorner}$東醫寶鑑${\Ircorner}$) and Dongui-Susebowon (${\ulcorner}$東醫壽世保元${\Ircorner}$) are asthma(喘), coughing(咳), fullness in the chest(胸滿), sweating symptoms(汗出), cold-heat symptoms(寒熱), dysphoria(煩躁) and sneezing. (2) Asthma symptom(喘) was shown to Soeumin's 4 exterior deficiency diseases, Taeumin's 1 exterior deficiency disease and 1 interior excess disease, and Soyangin's 1 interior excess disease. (3) Coughing symptom(咳) was shown to Soeumin's 1 extrerior deficiency disease and Taeumin's 1 interior excess disease. (4) Fullness in the chest(胸滿) was shown co Soyangin's 4 exterior excess diseases. (5) Sweating symptoms(汗出) was shown to Soeumin's 10 exterior deficiency diseases, Taeumins's 1 exterior deficiency disease, and Soyangin's 1 exterior defecieny disease. (6) Cold-heat symptoms(寒熱) was shown to Soyangin's 4 exterior excess diseases. (7) Dysphoria(煩躁) was shown co Soeumin's 1 exterior deficiency disease and 8 interior deficiency diseases, Taeumin's 1 interior excess disease, and Soyangin's 4 exterior excess and interior excess diseases. (8) Sneezing symptom was shown to Taeumin's 1 exterior excess disease.

Noju Oh Hui-sang was a Confucian who was active during the reign of King Sunjo in late Joseon Dynasty and he also was a master of the Sallim faction. Though he is known as an eclectic Neo-Confucian, he had profound knowledge in the study of Confucian classics as well through succeeding the family study handed down by his father Oh Jae-sun and his oldest brother Oh Yun-sang. This thesis hereby examines Noju's Confucianism doctrine and its characteristics. Noju's Confucianism doctrine is characterized significantly with the following aspects. First, its analyses are detailed overall and it annotates chapters and verses mostly related to Neo-Confucian theories on interpretation of the Confucian classics. Second, it conducts in-depth study not only on Chu Hsi's annotation but also on the small commentaries (小注) in Compendium of the Commentaries on Four Chinese Classics (四書集註大全). In terms of Chu Hsi's theory, however, Noju interprets Confucian classics while supplementing shortcomings on Chu Hsi's theory rather than opposing it. For opinions of all philosophers and scholars on small commentaries, it expresses rather critical theories than supporting ones. Third, it quotes many theories not only of Chinese Confucians but also of Korean ones. It mainly introduces theories of Namdang Han Won-jin, including those of Yi Yulgok. Among them, it particularly has frequent quotations from Han Won-jin's Kyoungyigimunrok (經義記聞錄). Fourth, Noju actively acknowledges senior Confucians' theories many times in quoting them but he also daringly points out their errors when a theory is thought not to be appropriate. He indicates errors one by one in theories not only of Uam and Yulgok but even of Mencius. Fifth, it especially discusses Book of Changes (周易) in depth. It tends to criticize Chengzi's I-Chuan (易傳) but accept Chu Hsi's Benyi (本義). It roughly explains Book of Changes in general but seldom directly accounts for trigrams of it other than Qian trigram and it has detailed explanation especially on Xicizhuan (繫辭傳).

This study is to investigate whether young Korean children have understanding for testing hypothesis. Questions explored are; First, do children have notions of testing hypothesis? Or, do they just produce an effect? Second, choosing between conflicting hypotheses, can children distinguish between experiments that would produce conclusive and inconclusive evidence? For this study, 15 first grade and 15 second grade children in elementary school located in Kyunggi area near Seoul participated. Data collection and analysis were based on interviews with children for two weeks. Children were presented two conflicted hypotheses to decide which one is correct through conclusive evidence and inconclusive evidence in the interview. The results showed that children(1st: 93.3%, 2nd: 81.3%) of each grade can distinguish between hypothesis and evidence to do testing hypothesis, and distinguish between conclusive and inconclusive evidence. In conclusion, most young children have understanding of testing hypothesis based on their familiar experiences, so it was possible for them to differentiate hypothesis from evidence in certain situations.

In this paper, uniaxial tensile tests of ETFE films with three kinds of thicknesses(100, 200, $250{\mu}m$) and two kinds of directions(machine direction & transverse direction) are performed and the tensile strength, the tensile strain at break and the Young's modulus of ETFE films are compared for two kinds of specimen types(2 & 5). It could be figured out that there are no significant difference between tensile strengths of two specimen types but the tensile strain at break and the Young's modulus of ETFE films are affected by the specimen types. And it is concluded that the uniaxial tensile test of specimen type 2 are more reliable than that of specimen type 5.
