The purpose of this study is to examine the historical consciousness and view of the three religions (Buddhism, Taoism, and Confucianism) of Won Cheon Seok who lived a period of historical transition from the end of the Goryeo Dynasty to the early Joseon Dynasty. Actively speaking for the public in his time and having the same attitude as the Neo-Confucian scholars in the end of Goryeo Dynasty, he kept criticizing the abuse of the power by powerful families who made the people fall into a state of distress and misery. He believed the dispatch of troops to conquer the Yodong region as a great opportunity to boost the valiant spirit of his country; however, the reality was quite opposite to his expectation as Lee Seong Gye had withdrawn the army troops at the Wihwado causing a great risk to his country. He took a very hard line stance against what Lee Seong Gye did. Although he was a Confucian scholar, he did not ignore Buddhism and Taoism and understood that after all the three religions were based on the same principle. His deep understanding of Buddhism and Taoism as well as Confucianism helped him to make sense of Confucianism even further. He was able to sublimate the worldly anguish coming from the Confucian thinking system by indulging himself deeply into the world view of Buddhism and Taoism. In the end, his view on the three religions was based on the idea that they taught the same principle. His view of the three religions with transactional features has a huge implication for the contemporary society in which various values and multiple cultures coexist and have more common grounds.

홍채 인식(Iris Recognition)은 동공과 흰자위 사이에 있는 홍채의 모양 패턴이 평생 변하지 않고, 사람마다 다른 패턴을 가진다는 특성을 이용하여 개인을 식별하는 기술로, 생체인식(Biometrics) 부분에서는 탁월한 식별력 및 신뢰성을 인정 받고 있다. 상당수의 기존 연구들은 원천 특허를 채택한 상태에서 성능 개선을 연구해 왔기 때문에 원천적인 한계를 가지고 있었다. 본 논문은 웨이블릿(Wavelet) 변환을 이용하여 특징을 추출하는 기존 방식과 다르게 프랙탈(Fractal) 방법으로 압축된 다수의 원 영상에 대해 입력된 영상의 유사도를 측정, 개인을 식별하는 새로운 홍채인식 방법을 제안한다. 이를 통해 타 연구들에서 제안했던 특별한 최적화 알고리즘을 사용하지 않고도 크게 떨어지지 않는 인식률을 얻을 수 있다.

A period of widespread damage to the surroundings by acid mine drainage was examined by modeling using column device, and the method to solve this problem was worked out. the underlying principle is to let the tailings permanently maintain a stable state not being reacted with the underground water, and the method is that the tailings and limestone are piled up alternatively. This reclamation method is economic and environmentally useful because of practical use of a large amount of low-grade natural limestone.

TQM(total quality management) is accepted as the powerful and holistic management innovation tools in the worldwide corporations since "Malcom Baldrige National Quality Award" model is established by US government. But nowadays, TQM′s roles and positions for the competitiveness is challenged from other many management innovations tools. This paper identifies the TQM′s roles and positions as the sources of sustainable competitive advantages through the examples of Japanese manufacturing corporations which enjoy the strongest positions since 1980′s in world market.

기업은 시대에 따라 변화하고 진화하였다. 농경사회, 상공업, 서비스, 기술/지식 중심의 벤처 기업 등 그 명칭이 가치 창출의 원천에 따라서 변화하여왔다. 본 논문은 현 시대의 '영적 자산'의 가치 창출을 목표로 하는 기업을 씨써클 기업이라 명하고 씨써클 기업의 개념과 특징에 대해서 알아보고자 한다

Confectionary and food products were collected from Korea and Japan. Types of packaging structure, amount of packaging materials used, basis weight of paperboard, and product to packaging ratio were evaluated for understanding confectionery and food packaging in both countries. Also, new packaging samples were designed and fabricated for reducing the use of packaging resources and for optimizing the product to packaging ratio. Korean confectionary products showed much higher empty space inside package than that of Japanese products, while food products were not significantly different between tow countries. There were no significant differences in the basis weight of paperboard collected. All of the re-designed confectionary products showed more than 15% saving in packaging resource compared to current confectionary products.

To protect the market for various products, existing authentication techniques using ID, hologram and RFID have been gradually developed. However, these methods can be easily exposed the authentication information, and also these exposed information easily copy. Thus, production of the counterfeit goods can not completely prevent. In this paper, to solve these problems, we designed JCVM file system for saving and managing the authentication information, user's information and a sales agency information into the smart card. And we designed and implemented an authentication protocol that can authenticate to avoiding exposure using processor of the smart card. Through this, this proposed scheme can prevent occurrences of the counterfeit goods. And also, can be used for authentication as any product that can attach the smart card.

현재까지의 보안 라우팅 프로토콜은 유무선에 관계 없이 페이로드 부분은 암호화가 되더라도 패킷 헤더의 내용이 평문 형태로 무방비하게 노출되며 라우팅 경로가 안전하게 보장되더라도 악의적인 노드에게 경로가 알려지는 것을 차단 할 수 없다. 또한 유선 환경과는 달리 Ad-hoc 네트워크와 같은 무선 상황에서는 전파의 전방향성 때문에 송수신 범위 내에 있는 노드들이 평문 형태의 라우팅 정보 및 송수신 노드의 정보를 수집하는 것을 방지 할 수 없다. 본 논문에서 제안하는 은닉 라우팅 프로토콜은 한쌍의 노드가 비대칭키 암호화 알고리즘을 통해 공유한 초증가 수열을 통해 송수신 노드를 은닉하면서도 정당한 수신 노드만 자신이 수신 노드임을 알 수 있는 기법을 제공함으로서 악의적인 노드가 라우팅 경로에 대한 정보를 수집하는 것을 원천적으로 차단한다.
