  • The objective of this study is to examine the regional distribution of Ssireum(Traditional Wrestling) of South and North Korea in the Japanese colonial era. The conclusions of this study are as follows. First, the "Joseon ui hyangto orak(Folk play in Joseon)" showed the record of performing 272 times of Ssireum in 226 regions of the whole nation. Second, the Ssireum of South Korea could be divided into five regions. Seoul/Gyeonggi-do performed Ssireum the most in Dano, Baekjung, and Chuseok while Chungcheong-do performed Ssireum in Baekjung and Chuseok. Jeolla-do and Gyeongsang-do performed Ssireum in Chuseok while Gangwon-do performed Ssireum in Dano and Chuseok. Third, the Ssireum of North Korea could be divided into three regions. All the Hwanghae-do, Pyeongan-do, and Hamgyeong-do performed Ssireum the most in Dano. Fourth, as the period when Ssireum was held the most in the whole nation, Dano, Baekjung, and Chuseok could be pointed out. Ssireum has the characteristics of large-scale play between village communities or regions, instead of individual game. Thus, the Ssireum that was played as a sport event under certain rules for a long time was settled down as a folk play of regional festivals such as Dano, Baekjung, and Chuseok. Fifth, as a folk play and a representative play of seasonal customs, Ssireum was distributed in the whole nation and handed down till today under the regional deviation of South and North Korea. Sixth, the unidentified regions of South Korea that did not perform Ssireum were six places including five dos such as Gapyeong Gyeonggi-do, Boseong Jeollanam-do, Jeju-do, Gunwi and Cheongsong Gyeongsanbuk-do, and Inje Gangwon-do. The regions of North Korea were six places including three dos such as Pyeongyang, Yangdeok, Gangdong, and Gaecheon of Pyeongannam-do, Bakcheon Pyeonganbuk-do, and Dancheon Hamgyeongnam-do. Total 12 places in eight regions were included. Seventh, the number of total items of play names presented in the "Joseon ui hyangto orak(Folk play in Joseon)" was about 6,400 types. Out of them, about 1,300 types were the items including how to play while about 5,100 types were the items presenting the play names only without explanations. Especially, in case of Ssireum, the periods of the lunar calendar were only specified in each region. Unfortunately, it was not possible to check the contents about the actual performance methods and types of Ssireum as they were omitted.

  • 인터넷 환경에서 DoS 공격을 이용한 해킹이나 주요 네트워크 기반 시설에 대한 파괴가 증가하고 있으며 이에 대한 공격범위가 점점 넓어지고 있다. 그 중 IETF IPsec WG에서 제안된 인터넷 키 교환 프로토콜(IKE)은 전자서명이나 DH 키 교환과 같은 공개키 기반의 연산을 수행하므로 쉽게 이러한 DoS 공격의 목표가 될 수 있다. 본 논문에서는 메모리나 CPU의 자원을 고갈시키는 DoS 공격을 방어할 수 있는 타원곡선 기반의 인터넷 키 교환 프로토콜을 제안하고, 이를 현재 IKE의 후보들과 비교 분석하였다. 또한, 제안된 타원곡선 기반의 인터넷 키 교환 프로토콜은 IKE 응답자의 부하를 기존의 IKE들 보다 감소시켰다. 이는 사용자가 많은 웹 서버나 메모리 혹은 연산능력의 제한을 가진 무선 장치에 효율적으로 이용될 수 있다.

  • 피쳐폰(Feature Phone)이 주를 이루던 초기 3G(Third Generation)는 사용자의 데이터 사용량이 많지 않았다. 그러나 스마트폰이 등장하면서 데이터를 이용한 서비스의 다양화, 저렴한 데이터 요금 정책으로 데이터 사용량이 대폭 증가하였다. 이동통신사가 예상하지 못한 데이터 사용량 증가로 3세대 망의 새로운 보안상 취약점이 나타났고 이를 이용한 DoS(Denial of Service) 공격이 발생하고 있다. 본 논문에서는 3세대 망에서 나타날 수 있는 DoS 공격의 하나인 DCH(Dedicated Channel) 고갈형 DoS 공격에 대한 논의하고 정상 사용자의 패킷 사용 패턴을 이용한 탐지 기법을 제안한다.

  • HEC-HMS model should be calibrated to be applied to these basins in Gangwon-do unlike the general basins. In the study, it is investigated whether the HEC-HMS model may be applied or not to Naerinchon basin where is the typical basin of Gangwon-do Additionally, the straightforword module of HEC-HMS for simulating the hydrologic characteristic of Gangwon-do basins well will be suggested by comparison of the numerical results with the observed data. The hydrologic results estimated by several modules such as Clark, SCS and Snyder methods in HEC-HMS model have been compared with the observed data for 1999~2000 storm events. It is concluded that Clark method are relatively applicable to the basins in Gangwon-do rather than the others methods. The parametric studies for HEC-HMS model should be studied further in order to apply to Gangwon-do basins more accurately.

  • 최근 MPEG-Immersive 표준화 그룹에서는 여러 위치에 존재하는 다수의 360 영상을 취득하고 처리하여 사용자에게 제한적인 화면 전환 이동에 따른 운동 시차(motion parallex)를 제공하는 3 degrees of freedom plus (3DoF+) 기술에 관한 표준화가 진행되고 있다. 이러한 3DoF+ 표준화 기술에서의 압축은 기존의 HEVC 코덱을 사용하나, 현재 존재하는 360 영상 사용자 시점 기반 스트리밍 기법을 3DoF+ 스트리밍에 적용하기 위해서는 기존의 360 영상과 다르게 영상 서로 간의 참조과정으로 인한 의존성으로 문제가 존재한다. 본 논문에서는 해당 문제점을 서술하고, MCTS(Motion-Constrained Tile Set)를 사용하여 보다 적은 디코더와 사용자 시점에 맞게 효율적으로 영상을 전송할 수 있는 MCTS 기반 타일 그룹 분할 방법을 제안한다.

  • MPEG 에서는 최대 6 자유도(6DoF)를 가지는 몰입형 미디어의 압축 표준화를 진행하고 있다. 360 비디오에 움직임 시차(parallax)를 추가한 것으로 정의되는 3DoF+의 가상 공간에서, 원하는 위치의 장면을 제공하려면 다른 위치에서 찍은 여러 비디오를 사용하여 임의의 원하는 시점의 뷰(view)를 렌더링 해야 한다. MPEG-I Visual 그룹에서는 이러한 3DoF+ 비디오의 효율적인 부호화 및 전송을 위한 표준화가 진행되고 있으며, 최근 시험모델(TMIV)을 개발하고 있다. 본 논문은 TMIV 에서 패치(patch)를 아틀라스(atlas)에 효율적으로 패킹하여 부호화 성능을 향상시킬 수 있는 패치 패킹 방법을 제안한다. 제안 방식은 패킹되는 패치들 간에 보호 대역(Guard Band)를 적용하여 패치간의 거리를 둠으로써 부호화로 인해 발생할 수 있는 아티팩트(artifact)를 줄여 최종 복원 뷰의 화질을 향상시킨다.

  • Anthracnose occurred on rapsberry grown in Gochang areas of Korea in 2003. The disease incidence was ranged from 1.1 to 2.6%. Anthracnose of rapsberry appeared as dark brown circular spots on naturally infected stems. The symptoms of infected stems were small brown to dark brown spots and gradually enlarged larger cylindrical dark brown lesions. The causal fungus of anthracnose isolated from the diseased plants was identifed as Colletotrichum coccodes based on the morphological and cultural characteristics. All isolates of C. coccodes were produced similar symptoms on the host leaves by artificial inocultion.

  • This paper aims to analyze the changes in the living arrangements of the elderly in Chejoo-do for the elderly housing supply by using census data. The conclusions are as follows; The rate of living alone and living with spouse only of the elderly have been increasing. The trend in county was higher than that in city. Living alone rate of the elderly of Chejoo-do was higher than that of Korean average. Even in the oldest old, living alone rate has been increasing in Chejoo-do. It is a unique phenomenon in Korea and similar with U.S. In Chejoo-do, it is strongly required to evolve elderly housing by universal design for living alone elderly in county as well as for living alone elderly in city.

  • In this paper we investigate (using AM1 semi-empirical as well as HF methods at the STO-3G, 3-21G, 6-31G, 6-$31G^*$ and 6-31+$G^{**}$ level) the conformations, geometrical parameters, Mulliken charges, and solvation effects of the triphosphate form of AZT (AZTTP), as well as the thymidine nucleotide (dTTP) structure. Our calculated geometrical parameters and Mulliken charges, with and without solvation effects, are correlated with recent experimental results.

  • Consumer preference, marketing environment and various agricultural policy were changed recently. So it is necessary to analyze the consumption behavior for selection the target market. In this paper, we analyzed the consumption behavior and the brand positioning using oriental melon. From the results of analysis, firstly, consumers' age, job, education and the number of member of household were effected to consumption behavior of oriental melon. Secondly, the marketing factor was the most important when purchasing oriental melon. Thirdly, the brand of Sung-Ju Oriental Melon was evaluated to the best brand on brand name, brand image and brand message.
