According to "Jinjak-yigwe(進爵儀軌)", a special banquet was held at Yungyungdang(演慶堂, a kind of royal theatre) to celebrate the 40th birthday of Queen Soonwon(純元王后) in 1828. This banquet is famous for the presentation of nineteen new Jungjae(呈才) repertoires that the Crown Prince Hyomyung(孝明) created. In order to explore the theoretical basis for the reproduction and presentation of Yungyungdang(演慶堂) Jinjak(進爵, a type of royal banquets), in this article, the imagination and experience of the presentation of Yungyungdang Jinjak are pursued, while focussing on audience's reception. In Yungyungdang Jinjak, King Soonjo(純祖), Queen Soonwon and the prince were the special audience; they participated in the procedure of Ye(禮, etiquette of ceremony) and also were considered as the characters of certain repertoire of Jungjae. Hyomyung arranged the spectacles from the myths of Taoist gods and immortal hermits, as well as historic episodes of the past emperors' elegant tastes of music. These mythic and historic images lead the audience toward the imagination and experience on the transcendental world. Hyomyung, managing the administration as the representative of King Soonjo, tried to show absolute royal authority through the splendid performances of Yungyungdang Jinjak, so as to overcome the politicaly difficult situation. He set up the sacred world for his father King Soonjo, distinct from the secular ordinary world, and emphasized his position as the bridge between the two sides. He expressed his filial duty through the devotion of performing arts to display absolute royal authority.

$L^*$ 기반의 Assume-Guarantee Reasoning[1]은 시스템 검증 시의 상태 폭발(state explosion)을 줄이는 데 크게 기여하였다. 그러나 시스템 검증에 소모되는 시간은 일반적인 모델 체킹 도구를 사용할 때 보다 크게 증가시킨다. 본 논문에서는 시스템의 검증에 소모되는 시간을 줄이기 위하여 $L^*$ 기반의 Assume-Guarantee Reasoning의 개선안을 제안하였다.

유비쿼터스 사회를 만들기 위한 핵심 기술인 RFID는 시간과 공간을 초월하여 우리에게 정보를 제공해 줄 것으로 기대되고 있지만, RFID 시스템이 가지고 있는 특성으로 인하여 프라이버시를 침해할 수 있다는 심각한 문제를 안고 있다 이를 해결하기 위한 방법으로 다양한 연구가 진행되어 왔지만 기존의 연구들은 보안상 문제점과 태그 및 백 엔드 데이터베이스의 과도한 처리능력을 요구하고 있다. 그러나 본 논문에서 제안하는 프로토콜은 해쉬함수와 XOR연산, 키 교환을 이용하여 스푸핑이나, 재전송 공격으로부터 안전 하면서도, 백 엔드 데이터베이스 안에서의 비교연산 횟수를 줄일 수 있는 경량화된 프로토콜을 제안한다.

본 논문에서 제안하는 시스템은 기존의 RFID System의 보안성을 높이기 위하여 2단계 인증처리를 통하여 안전성을 더 확보할 수 있게 되었다. 제안하는 시스템은 RFID Tag 인증 후 사용자의 추가적인 인증정보의 획득을 카메라를 통하여 사용자의 영상특징정보를 추출한다. 본 논문에서는 빠른 인증과 검색을 위하여 이미지 영역별 색상특징정보를 사용하여 추가적인 인증과정을 수행하게 된다. 제안하는 시스템을 실험한 결과 RFID Tag와 색상특징정보를 사용하여 출입인증을 하였을 경우 단일한 인증처리 시스템보다 정확한 결과를 얻을 수 있었다.

This study concerns a low head and kaplan turbine efficiency measurement using the acoustic scintillation flow meter(ASFM). The ASFM is one of absolute discharge measurement methods because it measures velocity-area of discharge with couples of transducers. This study shows that the highest efficiency of turbine is 87.7% and the efficiency is 85.8% in the rated output(600kW). The test result is reliable because the efficiency trend from this test is similar to the result of index test conducted in 1986. In this paper, the principle, measurement methods, application and test procedures of the test are discussed.

This paper is a study of the beginning pattern of simseul argument in the 19th century, based on the letter written by Hanju(1818~1886) and Mangu(1837~ 1902). In the text, I analyzed the theoretical differences between Mangu and Hanju that inherited from the study of Jungjae, is to expand the scope of the dispute between the Hanju and Mangu which to provide the beginning pattern of simseul argument. By revealing the theoretical difference between Hanju and Mangu, in the opposite direction, the content of the simseul argument between the Hanju and Jungjae's developed could be clearer. In the Hanjujip, there are nine letters to Mangu, there are also three letters to the Mangujip. These letters show a certain difference in the learning of the two people. So the text focuses on the content of these letters and reveals their theoretical differences, eventually it is confirmed that their theoretical differences lead to the beginning pattern of simseul argument. In particular, interpretation of LiKi leads to interpretation of Sim. Sim interpretation centers on the interpretation of the Zhuxi's 'Ki of Jungsang' meaning, while Hanju emphasizes to see as Lee, Mangu emphasizes that as the sum of Liki. 'Ki of Jungsang' is an interpretation of Zhuxi' Sim, and in the end, interpretation of 'Ki of Jungsang' means interpretation of Sim. Thus, while Hanju tried to see of Li, Mangu wanted to see at the sum of LiKi. This is simseul argument between Hanju and Man-gu, which was unfolded in the extension of the 19th century's simseul argument of erection. Through their argument, they are going to use it as an opportunity to review details of how the debate started in the Toegye school.

Recently, a few image-processing based mobile urine testers have actively been studied since the urine-analysis result can be available to the user in real time immediately after the test is done. However, the accuracy of test result can be severely degraded due to variable illumination environments and a variety of manners to capture the image with a camera embedded in the smartphone according to different users. This paper proposes the Check4Urine system, a novel smartphone-based portable urine-analysis tester and provides three techniques to improve such a performance degradation problem robust to various test environments and disturbances, which are the compensation algorithm to correct the varying illumination effect, an urine strip detection algorithm robust to edge loss of the object image, and the color decision algorithm based on the pre-processed reference table. Experimental results show that the proposed Check4Urine system increases the accuracy of urine-analysis by 20-50% at various test conditions, compared with the existing image-processing based mobile urine tester.

We analyzed two radiocarbon-dated lagoonal sediment cores from Cheonjinho and Ssangho using various biogeochemical methods. As a result, the start times of rice agriculture are estimated to be AD 780 for Cheonjinho and 100 BC for Ssangho. There is a large temporal difference in the beginning of rice agriculture between two study sites even though they are closely located on the coast. This result indicates that pollen records are not sufficient to approximate the start time of rice agriculture accurately. A temporal lag seems to exist between the time when rice agriculture was first introduced and the time when full-scale rice agriculture began in the Yeongdong region, probably because of low agricultural productivity. In both study sites, rice agriculture intensified and slope erosion increased 250 years after full-scale agriculture began. This suggests that intensified rice agriculture resulted in an increased number of inhabitants, settlement expansion to hilly areas, and the consequent deforestation.

Purpose: Recently, structural defects in old safety management facilities have led to the collapse of buildings and facilities. The purpose of this study is to develop guidelines for the installation of regular monitoring systems that determine the optimal sensor location for monitoring exhibition space building sensors equipped with visual elements in order to analyze the risk signs of exhibition space buildings and develop measurement technology. Method: The components, installation locations, alarm criteria, and management measures of the instrument are presented. Result: A measure was proposed to determine the location of sensors, secure signal processing technology for analysis by having unified visual perception, and configure optimal 'risk sign detection' based on sensor monitoring through test-bed operation. Conclusion: The results of this study can be prepared against the disasters that may arise from the collapse of exhibition buildings, and contribute to strengthening safety management capabilities.
