In the modern society in which globalization is ongoing in the overall culture social culture, various efforts are being made by each country around the world in order to search for the distinctive cultural identity and creativity. Recognizing the importance of the 'Korean' tradition, South Korea is also actively engaged in researches to develop design utilizing it and to apply it in real life. Here, developing Korean design does not simply refer to borrowing and imitating the traditional form or color but refers to generating a new, original and ethnic aesthetic consciousness that conform to the era that we are currently living in based on the unique ideology and sentiment inherent in its formativeness. Despite the fact that research on Korean traditional culture has continued for a long period of time, it is considered that such phenomenon continues to take place because the establishment and utilization of Korean culture identity is still insufficient. There, research on various fields based on new understanding with regards to our culture and the development of design utilizing it is in dire need. This study aims to analyze the said usage form and formative characteristics and the possibility of modern application focused on the lines and patterns which are most frequently mentioned when discussing about the Korean traditional formative beauty of Korea.

This thesis aims to suggest probability of modern confrontation of Yulgok YiYi's thought. For this, find out the meaning of Li-Qi-Zhi-Miao(理氣之妙) and through the Qi-Fa-Li-Cheng-Yi-Tu(氣發理乘一途), and Li-Tong-Qi-Ju-Shou(理通 氣局說), Yin-Xim-Do-Xim-Shou(人心道心說), he creatively reveal the relation of Xin(心) Xing(性) Qing(情) Yi(意) continually. On one side he suggested the way of ideal man, on the other side he was showed adaptablity to the real world. So I think Yulgok had placed emphasis on the Zhongyong(中庸) and Yijing(周易), so he point out the meaning of ShiZhong (時中). Then he had high ideals practical Zhi-Zhonghe((致中和). So This paper is to find out his foundation of epistemology, and then to know It's modern meaning of methodology of moral Education's Implication on the relation of Xin(心) Xing(性) Qing(情) Yi(意). So We ca find out Ji(機) is very important the transition of Qi-Zhe(氣質).

A series of the tragic 16th-century Sahwas sent Toegye into the depths of despair. In the face of the ensuing social disruption in which any criterion or direction is utterly lost, he could not but to reexamine the problem of human nature and good and evil. For Toegye, criterion or direction is connected with Principle, and human nature and the problem of good and evil are related with Mind. In other words, these problems are none other than the question: "As the subject of history and society, how a human being can set principle in a real world and realize it? How one can successfully control his wants and feelings with his rationality?" Toegye proposes that while laws and regulations should be reformed when they are outdated, good laws and regulations are not necessarily to be discarded. He also warns that ideal governance is not likely to be realized if only too conservatives take the lead while radicals, depended upon exclusively, would create too many problems.

Mokjae Lee Samhwan's "MaengHoEum" is the three poems of the Chinese quatrain of 5word 7poetry created according to the previous age. This poem is distinguished from the poem of the general "MaengHoHaeng" series because of it was created in the form of modern-style poetry of series, not a poetry of 5word or 7word or length phrase in a poem. The "MaengHoEum" of MokJae seems to have been built around 1801year when he was 73 years old. Therefore, his "MaengHoEum" can be called an allegory poetry or a society poetry and his poetry can be said that it was created under the criticism of the corrupt political power of the contemporary society, and the 'fierce tiger' which appeared in his poem refers to the factions of Noron Byek line which was the ruling power at that time. However, if you look at the "MaengHoEum" of MokJae, you will see a criticism of the real world, but the feeling is not intense or the description is not concrete. Although his poetry depicts the absurdity of the present reality, but he does not show positive criticism of reality or strong resistance. This characteristic, which can be seen in his poem "MaengHoEum", is the result of the study he pursued for the his life and is thought to be due to the weight of reality. The contradictions of the time of the Mokjae were never silent to him, but on the other hand he could not reveal his own struggle on the surface of the poem. Between his descendants, influenced by his actions, and the stinging gaze watching him, he had no choice but to end his feelings internally.

A Buddhist relic deposit was discovered from the three storied stone pagoda which was called as Seokgatap of Bulguksa temple in Gyeongju in 1966. In this relic deposit, several clumped papers written in ink which were found from the pagoda. These manuscripts are one of the most valuable materials for understanding Korean Buddhism and Buddhist Art History. In this paper, I examined several terms for pagoda subsidiaries found in these manuscripts, which have not been known to us up to recently. In addition, I compared these terms to the real pagodas or pagoda images in Korea. The manuscripts from Seokgatap pagdoa were composed of three different kinds of records; (1) "Record for the Repair of Mugujeonggwangtap Pagoda (無垢淨光塔重修記, 1024)"; (2)"Record for the Reconstruction of West Pagoda (西石塔重修形止記, 1038); (3)"Lists of Donors for the Reconstruction of the Pagoda in Bulguksa temple (佛國寺塔重修布施名公衆僧小名記, 1038). The terminology describing pagoda was appeared in the first and the second records. In the "Record for the Repair of Mugujeonggwangtap Pagoda", there are more than ten terms, which are presumed to be the words describing some upper decorative parts of a stone pagoda. However, in the "Record for the Reconstruction of West Pagoda", there are fifteen terms which would describe the body and base parts of the Seokgatap pagoda. These new terms for pagoda subsidiaries appeared in the manuscripts of Seokgatap Pagoda are very significant materials in understanding Korean Buddhist Art, because they show the practical terms which were used in the eleventh century Buddhism of Korea, but never known to the modern academic world. The manuscripts of Seokgatap Pagoda have not been deciphered perfectly yet, so they have to be examined with more precise as well as with wider view of Buddist and Art History.

In the recent years, malicious codes called malware are having shown significant increase due to the code obfuscation to evade detection mechanisms. When the code obfuscation technique is applied to malwares, they can change their instruction sequence and also even their signature. These malwares which have same functionality and different appearance are able to evade signature-based AV products. Thus, AV venders paid large amount of cost to analyze and classify malware for generating the new signature. In this paper, we propose a novel approach for detecting metamorphic malwares. The proposed mechanism first converts malware's API call sequences to call graph through dynamic analysis. After that, the callgraph is converted to semantic signature using 128 abstract nodes. Finally, we extract all subgraphs and analyze how similar two malware's behaviors are through subgraph similarity. To validate proposed mechanism, we use 273 real-world malwares include obfuscated malware and analyze 10,100 comparison results. In the evaluation, all metamorphic malwares are classified correctly, and similar module behaviors among different malwares are also discovered.

Various security devices are used to protect internal networks and valuable information from rapidly evolving cyber attacks. Firewall, which is the most commonly used security device, tries to prevent malicious attacks based on a text-based filtering rule (i.e., access control policy), by allowing or blocking access to communicate between inside and outside environments. However, in order to protect a valuable internal network from large networks, it has no choice but to increase the number of access control policy. Moreover, the text-based policy requires time-consuming and labor cost to analyze various types of vulnerabilities in firewall. To solve these problems, this paper proposes a 3D-based hierarchical visualization method, for intuitive analysis and management of access control policy. In particular, by providing a drill-down user interface through hierarchical architecture, Can support the access policy analysis for not only comprehensive understanding of large-scale networks, but also sophisticated investigation of anomalies. Finally, we implement the proposed system architecture's to verify the practicality and validity of the hierarchical visualization methodology, and then attempt to identify the applicability of firewall data analysis in the real-world network environment.

According to the World Health Organization (WHO), air pollution is a typical health hazard, resulting in about 7 million premature deaths each year. Sulfur dioxide (SO2) is one of the major air pollutants, and the combustion process with sulfur-containing fuels generates it. Measuring SO2 generation in large combustion environments in real time and optimizing reduction facilities based on measured values are necessary to reduce the compound's presence. This paper describes the concentration measurement for SO2, a particulate matter precursor, using a wavelength modulation spectroscopy (WMS) of tunable diode laser absorption spectroscopy (TDLAS). This study employed a quantum cascade laser operating at 7.6 ㎛ as a light source. It demonstrated concentration measurement possibility using 64 multi-absorption lines between 7623.7 and 7626.0 nm. The experiments were conducted in a multi-pass cell with a total path length of 28 and 76 m at 1 atm, 296 K. The SO2 concentration was tested in two types: high concentration (1000 to 5000 ppm) and low concentration (10 ppm or less). Additionally, the effect of H2O interference in the atmosphere on the measurement of SO2 was confirmed by N2 purging the laser's path. The detection limit for SO2 was 3 ppm, and results were compared with the electronic chemical sensor and nondispersive infrared (NDIR) sensor.

Through photogrammetry techniques, what current researches can achieve at present is rough 3D mesh and color map of objects, rather than usable photo-realistic 3D assets. This research aims to propose a new method to create photo-realistic 3D assets that can be used in the field of visualization applications. The new method combines photogrammetry with computer graphics modeling. Through the description of the production process of three objects in the real world - "Bullet Box", "Gun" and "Metal Beverage Bottle," it introduces in details the concept, functions, operating skills and software packages used in the steps including the photograph object, white balance, reconstruction, cleanup reconstruction, retopology, UV unwrapping, projection, texture baking, De-Lighting and Create Material Maps. In order to increase the flexibility of the method, alternatives to the software packages are also recommended for each step. In this research, 3D assets are produced that are accurate in shape, correct in color, easy to render and can be physically interacted with dynamic lighting in texture. The new method can obtain more realistic visual effects at a faster speed. It does not require large-scale teams, expensive equipment and software packages, therefore it is suitable for small studios and independent artists and educational institutions.
