Seonya theory(宣夜說) was one of the most important metagalaxy model in the ancient times. Unlike the other important metagalaxy model, it had the concept that the sky is not in the solid state but is just the infinite space which is full of gi(氣). But Seonya theory, though it had partially the superb academic thought, it had gradually become the forgotten thing among scholars in the ancient times. Since then, once forgotten Seonya theory was reconstructed again in Song(宋) dynasty, and Jangjae(張載) did the main role at that time. In the historical sequence like this, we need to take notice of one thing that "Hwangjenaegyeong(黃帝內經)" had worked on Jangjae as the origin of his sunya theory. So we also need to take notice of one thing that "Hwangjenaegyeong" is just a rare document that comprises the academic thought of Seonya theory which had once been forgotten in ancient times. Based on the historical situation like this, this study is focused on the idea that the discuss on the Jangjae's Seonya theory would be a good way to think of the cosmic theory of "Hwangjenaegyeong" and the theoretical thought derived from them. So this study will first look into the academic characteristics of Seonya theory of ancient times and of "Hwangjenaegyeong" and through the study on the academic characteristics of Jangjae(張載)'s Seonya theory, will also think of the significance of the thought of Jangjae's Seonya theory that would be some help to the research on "Hwangjenaegyeong".

The purpose of this study is to know the characteristics of the ancient city through the basic composition of Jericho city. But there are little documents in the ruins of Jericho, and so there are the limit to understand the basic characteristic of the ancient city. And so this study is going to know the symbolic meaning of the ancient city of the Jericho city, through the transcriptions remains. Producing the concept that Jericho is the old city in the world, this study is significant that utilizing with the basic document of helping to understand the basic composition and characteristic in the ancient city. Also because the bible documents of Jericho is explained the city in the bronze age, this study sets bounds to BC 15C, and to know the symbolic system in Jericho. In the christian transcriptions, it is represented the Jericho city BC 15C. Jericho city here is described the type of the labyrinth is composing of the city in the center and surrounding by the walls. The circular type of the labyrinth city has symbol of the 'protect' having the magic power against the opposite party. Also the walls of labyrinth are the boundary territory of 'abstract conception' to round seven times. The center in the shape of Jericho is 'closing field' against circumferences, and this is different from the labyrinth on the floor in the medieval Cathedral is symbolized 'opening field'

In this work, scientific and systematic analysis was conducted for finding out the methods and techniques of ancient ink stick making. Analysis the ancient ink stick on ancient documents and wooden writing as letter or painting, we concluded as followings. From the analysis of ancient wood by dendrochronology, wood was cut at 1899, which provided the information on the year of ink stick's made on writing on ancient wood. Single particle size for soot of ancient ink stick was 107 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, compared to 38 to 86 nm on the letter on ancient 12 paper document. Aggregate particle size was 370 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, but 206 to 318 nm for aggregate particle size on 12 paper documents. There was similar pattern between single particle size and aggregate particle size of soot, which might provide the information of raw material for ancient ink. From infra-red and Raman spectroscopic analysis of sheet of writing on paper or wood, there was severe interference from background material (paper or wood). From Raman spectroscopic analysis of ancient ink carefully separated from ancient wood, spectrum pattern was closer to ink stick made by the soot from pine burning.

This study analyzed ancient documents and established petrological database through extensive field investigation of provenance sites to presume stone source areas of the Seoul City Wall. By summarizing the ancient documents, the rampart stone was mostly supplied from a stony mountain adjacent to the City Wall in the early Joseon period, whereas the stone was provided from fixed quarry outside the City Wall in the late Joseon period. As a result of the petrological investigation based on quarries recorded in the ancient documents, pinkish granite and leucogranite were distributed as a whole, and the granitoid rocks are similar in mineralogical compositions and geochemical behavior characteristics. However, the pinkish granite with magnetic-series show that the magnetic susceptibility increased from the north slope of Namsan Mountain to Bulamsan Mountain. The leucogranite with ilmenite-series mainly occurred along the boundary between granite and gneiss from Yongmasan Mountain to Inwangsan Mountain. Consequently, the important petrological indicators for presumption of stone source areas are the rock color and the magnetic susceptibility. In addition to the petrological features, the reliability for provenance interpretation should improve considering stone quantities in the quarries, transportation distance and technical skills.

Encryption technology is to hide information in a cyberspace built using a computer and to prevent third parties from changing it. If a malicious user accesses unauthorized device or application services on the Internet of objects, it may be exposed to various security threats such as data leakage, denial of service, and privacy violation. One way to deal with these security threats is to encrypt and deliver the data generated by a user. Encrypting data must be referred to a technique of changing data using a complicated algorithm so that no one else knows the content except for those with special knowledge. As computers process computations that can be done at a very high speed, current cryptographic techniques are vulnerable to future computer performance improvements. We designed and implemented a new encryption program that combines ancient and modern cryptography so that the user never knows about data management, and transmission. The significance of this paper is that it is the safest method to combine various kinds of encryption methods to secure the weaknesses of the used cryptographic algorithms.

Objectives : There are plenty of medical record of acupuncture & moxibustion in Traditional East Asian medicine(TEAM). We performed this study to find out the hidden criteria lies on this record to choose proper acupoints. Methods : "Zhenjiuzishengjing", ancient TEAM book was analysed using document clustering techniques. Corpus was made from this book. It contained 196 texts driven from each symptoms. Each texts converted to vector representing frequency of 349 acupoints. Distance of vectors calculated by weighted Euclidean distance method. According to this distances, hierarchical clustering of symptoms was builded. Results : The cluster consisted of five large groups. they had high corelation with body part; head and face, chest, abdomen, upper extremity, lower extremity, back. Conclusions : It assumes that body part of symptom is the most importance criteria of acupoints selecting. some high similar symptom vectors consolidated this result. the other criteria is cause and pathway of illness. some symptoms bound together which had common cause and pathway.

Text, as one of the most influential inventions of humanity, has played an important role in human life since ancient times. The rich and precise information embodied in text is very useful in a wide range of vision-based applications such as the text data extracted from images that can provide information for automatic annotation, indexing, language translation, and the assistance systems for impaired persons. Therefore, natural-scene text detection with active research topics regarding computer vision and document analysis is very important. Previous methods have poor performances due to numerous false-positive and true-negative regions. In this paper, a fully-convolutional-network (FCN)-based method that uses supervised architecture is used to localize textual regions. The model was trained directly using images wherein pixel values were used as inputs and binary ground truth was used as label. The method was evaluated using ICDAR-2013 dataset and proved to be comparable to other feature-based methods. It could expedite research on text detection using deep-learning based approach in the future.
