실내 환경에서 Chirp Emission과 Echo Signal을 이용한 심층신경망 기반 객체 감지 기법

남현수,정종필,Nam, Hyunsoo,Jeong, Jongpil 한국인터넷방송통신학회 2021 한국인터넷방송통신학회 논문지 Vol.21 No.3

인간은 오감 (시각, 청각, 후각, 촉각, 미각) 중 시각 및 청각 정보를 위주로 사용하여 주변 물체를 인식한다. 최신의 객체 인식과 관련한 주요 연구에서는 주로 이미지센서 정보를 이용한 분석에 초점이 맞추어져 있다. 본 논문에서는 다양한 chirp 오디오 신호를 관측공간에 방출하고 2채널 수신센서를 통해 echo를 수집하여 스펙트럼 이미지로 변화시킨 후 딥러닝을 기반으로 이미지 학습 알고리즘을 이용하여 3D 공간상의 객체 인식 실험을 진행하였다. 본 실험은 무향실의 이상적 조건이 아닌 일반적인 실내 환경에서 발생하는 잡음 및 echo가 있는 환경에서 실험을 진행하였고 echo를 통해 객체 인식률을 83% 정확도로 물체의 위치 추정할 수 있었다. 또 한 추론 결과를 관측공간과 3D Sound 공간 신호로 mapping 하여 소리로 출력하여 3D 사운드의 학습을 통해 소리를 통한 시각 정보를 얻을 수 있었다. 이는 객체 인식 연구를 위해서 이미지 정보와 함께 다양한 echo 정보의 활용이 요구된다는 의미이며 이런 기술을 3D 사운드를 통한 증강현실 등에 활용 가능할 것이다. Humans mainly recognize surrounding objects using visual and auditory information among the five senses (sight, hearing, smell, touch, taste). Major research related to the latest object recognition mainly focuses on analysis using image sensor information. In this paper, after emitting various chirp audio signals into the observation space, collecting echoes through a 2-channel receiving sensor, converting them into spectral images, an object recognition experiment in 3D space was conducted using an image learning algorithm based on deep learning. Through this experiment, the experiment was conducted in a situation where there is noise and echo generated in a general indoor environment, not in the ideal condition of an anechoic room, and the object recognition through echo was able to estimate the position of the object with 83% accuracy. In addition, it was possible to obtain visual information through sound through learning of 3D sound by mapping the inference result to the observation space and the 3D sound spatial signal and outputting it as sound. This means that the use of various echo information along with image information is required for object recognition research, and it is thought that this technology can be used for augmented reality through 3D sound.

태안 청자운반선 출토 고려 목간의 현황과 내용

임경희(Lim, Kyoung-hee),최연식(Choe, Yeon-shik) 한국목간학회 2008 목간과 문자 Vol.1 No.-

2008년 충남 태안 대섬 수중발굴조사를 통해서 2만 여점에 달하는 양질의 고려청자와 선원들이 사용하던 솥, 물동이 등의 선상생활용품이 인양되었다. 2000년 인양예정인 고려 시대 청자 운반선과 함께 이번 발굴에서 무엇보다도 중요한 것은 고려시대 목간이 출토되었다는 점이다. 충남 태안 대섬에서 출토된 목간은 파손된 부분이 많으며, 특정한 모양이 반복되는 것은 아니어서 형태상 분류는 어렵다. 반면 내용이 반복되는 것들이 많이 있어 내용별로 ‘耽津’이 적혀 있는 A형, ‘安永戶’가 적혀 있는 B형, ‘崔大卿’이 나타나는 C형, ‘柳將命’의 D형, 그리고 부호가 있는 E형으로 분류하였다. 목간 내용을 통해 청자운반선은 ‘耽津’에서 출발했다는 사실을 알 수 있다. 강진의 어느 세력인지는 앞으로 연구를 더욱 진행해 봐야 할 것이다. 도자기는 일정한 단위로 묶여 있는데, 목간묵서 중에 ‘?’라는 단위가 나타난다. 정확히 어느 정도의 수량인지는 현재까지는 알 수 없다. 이외에도 ‘八十’ ‘?七’ ‘?’ 등 구체적인 수량이 기록된 경우도 있다. 도자기는 ‘在京’의 ‘隊正仁守’, ‘安永戶’ 등에게 운송되었다. 이들은 신분이라든가 용법으로 보아 중간 유통자일 가능성이 크다. 목간에는 ‘崔大卿宅上’ ‘柳將命宅上’이라는 문구도 보이는데, 대경이나 장명은 모두 정식 관제에는 드러나지 않지만, 대경은 3품에 해당하는 관직명의 이칭, 장명은 무반직의 이칭으로 생각한다. 이들의 경우 최종 소비자였을 것으로 추정할 수 있다. 목간의 여러 곳에는 동일한 수결이 반복되어 나타나는데 도자기의 적재와 운반을 책임지는 사람의 것으로 보인다. 이번에 출토된 고려시대 목간은 화물의 물표 역할을 했던 것으로, 화물의 발송자, 운송자, 중간유통자, 최종 소비자가 드러나 있어 고려시대 도자기 운반과 유통과정을 연구하는데 중요한 자료가 될 것이다. 미술사에서는 도자기 번조방법, 문양, 기형 등을 근거로 하여 그 생산지를 추정하였고, 편년 연구를 진행해왔다. 또한 최근에는 도자기의 성분분석을 통하여 산지추정을 하는 과학적인 연구도 이루어지고 있다. 그러나 도자기의 운반이나 유통 과정 등은 연구의 공백으로 남아 있었다. 이번 대섬 출토 목간은 이러한 공백을 메울 수 있는 중요한 자료가 될 것이다. 이는 도자기에 한정되지 않고, 고려시대 경제활동에서 상품의 운송, 유통 등의 문제를 풀어가는 실마리도 된다. Some 20,000 quality celadon pieces of the Goryeo Dynasty were recovered from a sunken vessel earlier this year, as well as utensils used by sailors, such as pots and water jars. The artifacts were discovered during an underwater excavation survey in waters off Daeseom Island in Taean, South Chungcheong Province. Along with the vessel that sank with its precious cargo of celadon of the Goryeo Dynasty, which will be salvaged in 2008, what is most significant in this discovery is that mokgan (strips of wood used as writing material before paper was available), of the Goryeo Dynasty were a1so found. The mokgan discovered in waters off Daeseom in Taean, South Chungcheong Province are mostly damaged and it is difficult to c1assify them according to forms, as specific patterns are not repeated. On the other hand, in terms of content, many of them are repetitivethus they are classified in terms of content into Type A, on which the word "Tamjin(耽津: the ancient name of Gangjin)" is written; Type B on which the name "Ahn Yeong-ho(安永戶)" is written; Type C on which the name "Choi Daegyeong(崔大卿)" is written; and Type D on which "Yu Jangmyeong(柳將命) is written; and Type E with various symbols. Through the description on the mokgan, it was learned that the celadon carrier started from Tamjin. Further research is needed to identify which forces of Gangjinit refers to. The celadons were bundled by certain units and a unit of gwa(?) is found. It is not yet known what amount gwa refers to precisely. Besides, there were cases where exact quantities were recorded, such as 80(八十), 37(?七) and 20(?). The ceramics were transported to Daejeonginsu(隊正仁守) and Ahn Yeong-ho(安永戶) who were most likely the interim distributors given their class and usages. Found on the mokgan were words such as 崔大卿宅上(Choi Daegyeong Taeksang) and 柳將命宅上(Yu Jangmyeong Taeksang). It is believed that daegyeong is another name for official rank 3 and jangmyeong refers to another title for military officers. They are presumed to be the final clients. In several parts of the mokgan are found the same signatures, which appear to be those of a person in charge of loading and tranportation of the ceramics. The mokgan of the Goryeo Dynasty discovered in the latest underwater excavation were used as cargo tags and showed the names of thesender, the transporter, interim distributor, and the final client. These mokgan will thus serve as important material in researching the transportation and distribution of pottery during the Goryeo Dynasty. In art history, production locations have been presumed on the basis of methods of firing ceramics, patterns and forms and, based on this, chronological research has been conducted. Moreover, in recent years, scientific research to identify production locations has been conducted by analyzing the composition of ceramics. However, the transportation and distribution process of ceramics has been left the void of research. The mokgan discovered in waters off Daeseom will become an important research material to fill this void. They will also provide clues to solve such issues as the transportation and distribution of goods in trading activities during the Goryeo Dynasty, not merely being limited to the area of ceramics.

양친매성 ( 2-butoxyethanol 과 물 혼합계에서의 과잉 엔탈피 및 활동도 계수

임경희(Kyung Hee Lim) 한국유화학회 2000 한국응용과학기술학회지 Vol.17 No.2

Excess enthalpies (H^E) were measured by isothermal flow calorimetry for the nonionic amphiphile 2-butoxyethanol/water mixtures at 10 different temperatures (48.5 to 70℃) around and above the lower consolute solution temperature, T_lc. H^E exhibits U-shape for the binary mixtures, and is large and negative which reflects substantial interaction between two chemical species. When the commonly used, semi-empirical Redlich-Kister (RK) polynomials were fitted to the measured H^E, plots of H^E vs. weight fraction provided more accurate fitting with fewer parameters than conventionally drawn H^E vs. mole fraction plots. This was due to the enhanced symmetry of H^E vs. weight fraction plots. Using the fitted Redlich-Kister polynomials and the Gibbs-Helmholtz relation, temperature dependence of the activity coefficients were found and compared to the values determined from vapor-liquid equilibria. The activity coefficients were in the range of one to three, indicating that the binary system deviates from ideality but not substantially. They slightly depended on temperature and the temperature effect was equivalent to 10 % change in the activity coefficients. Key words: Excess enthalpy, Partial molar enthalpy, Redlich-Kister polynomial, LLE phase composition, Activity coefficient

Any theory of liquid should account for interactions between molecules, since molecules in a liquid are close to each other. For this matter statistical-mechanical methodology has been used and various models have been proposed on the basis of this methodology. Among them Kirkwood-Buff solution theory has attracted a lot of interest, because it is regarded as being the most powerful. In this article Kirkwood-Buff solution theory is revisited and its key equations are derived. On the way to these equations, the concepts of pair correlation function, radial distribution function, Kirkwood-Buff integration are explained and implemented. Since complexity of statical mechanics involved in this theory, the equations are applied to one-component systems and the results are compared to those obtained by classical thermodynamics. This may be a simple way for Kirkwood-Buff solution theory to be examined for its validity.
