Connection is necessary element of every structure. Connection is important element to increase composition rate of composite beam. Welding joint has been used at composit beam-column connection. Welding joint's quality control is harder than high strength bolt's one. This study based on the experiments of 4 specimens by beam-column connection test. In this paper, we analyze behavior of composite beam-column connection through an experimental study and wish to present application possibility to TSC beam.

본 연구는 음식물류 폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 기존 음식물류 폐기물 공공자원화 시설에 대한 실태조사를 통해 운영에 따른 문제를 분석하였으며, 이를 위하여 음식물류 폐기물의 발생량 및 자원화 현황, 공공 및 민간 자원화시설 현황, 전국의 주요 음식물류 폐기물 공공자원화 시설의 실제 운영과정에서 나타난 문제점을 분석한 결과는 다음과 같다: 현재 국내 음식물류 폐기물의 분리 수거량은 약 97%인 것으로 나타났다. 그리고 대부분의 공공 자원화시설은 음식물류 폐기물의 자원화가 아닌 단순처리에 급급한 것으로 나타났으며 경제성도 없는 것으로 분석되었다. 특히, 바이오가스시설 대부분은 실시설계와는 달리 가스 생산량 및 수요량이 전혀 맞지 않는 것으로 나타났다. This study is conducted to find out problems of the public food waste recycling facility and its improvement. Through a research on the actual condition, it is possible to analyze the problem of operation. Moreover, for this improvement, with analysis of the current state of recycling rate including its generation and the problem that can be shown from the real operation of the public/private food waste recycling facility, the results are as follows: It can be shown that the current amount of domestic food waste resource recycling is about 97 %. Almost every public recycling facility is analyzed to be economically infeasible and is not for recovery but to simple disposal. Especially, most of Biogas facilities appeared that amount of production and demand is not appropriate differed from enforcement design.

본 연구는 음식물류폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 현재 운영중인 음식물류 폐기물의 가동율 현황과 자원화 시설의 확충 계획에 대한 분석을 통해 시설의 무분별한 신규건설로 인한 국가의 예산이 낭비되지 않도록 그 대안을 제시하였으며, 그 결과는 다음과 같다. 공공 자원화시설 신규 확충보다는 기존 민간 자원화시설을 활용하여 예산을 절약하고 음식물류 폐기물의 안정적인 처리는 물론 자원순환을 촉진시킬 수 있는 정책전환이 필요하다. 음식물류 폐기물을 친환경적인 방법으로 안정적으로 처리하기 위해서는 제도개선이 필요하며, 이를 위해 민간 자원화시설 가동률 저하를 줄일 수 있는 준공영제 도입이 필요하다. 또한, 공공 자원화시설의 검증된 기술과 경제성 확보 방안 마련이 필요하다. This study is conducted to find out the problems of the public food waste recycling facility operation and its improvement. In order to save the national budget by analyzing plans to expand including operation rate for the food waste recycling facility, the alternative ways are suggested. The result can be as follows: Policy switch is required not only to save budget and stable disposal of food waste but also to promote resource recycling rather than expanding public facilities. In order to change the policy for stable and eco-friendly disposal of food waste, it is necessary to adopt semipublic system that prevent the decline of the rate of operation of private resource recycling facility. Furthermore, it is required to prepare both qualified technologies of public resource recycling and the ways of profitability secure.

Background and Objectives: The colorectal cancer rates 4th in the total cancer prevalence in Korea. The clinical patient demographics were considered with the incidence rate of the colon and rectal cancer. The clinicopathological factors were analyzed for the 5 year survival rate. Materials Methods: Of the 282 patients who were operated from Jan. 1, 1992 to Dec. 31, 2001 and diagnosed by pathological biopsy as colo-rectal cancer, 234 patients were followed up. The age, sex, location of the cancer, TNM stage, operation method, histopathological classification, metastatic region, complications after operation and the survival rate were investigated. Results: Of the 234 patients, male and female consisted of 120 cases (51.3%) and 114 cases (46.7%), with an average age of 61.6 years. The average follow up period was 52.3 months and the peri operative mortality was 5.6%. The site of the cancer was most frequent at the rectum with 127 cases (54.3%). The patients were classified according to the TNM stages with 38 cases of stage 1 (16.2%), 98 cases of II (41.9%), 72 cases of III (30.8%) and 26 cases of IV (11.1%). The 5 year survival rate in the age group older than 50 was 63.3 % and 73.5% in the group younger than 50. In regard to the operation type, the 5 year survival rate was 65.4% for elective operation and 65.8% for emergency operation. The 5 year survival rate for well differentiated, moderately differentiated, poorly differentiated cancer, and mucinous adenocarcinoma was 73.7%, 60.2%, 58.3%, and 92.6%, respectively. The 5 year survival rate of each of the TNM stage is 81.1%, 74.8%, 57.0%, and 11.5% for Classes I, II, III, and IV, respectively. Conclusion: The clinical factors were analyzed for the 5 year survival rate with no statistical significance for the age, sex, and location of the cancer. The TNM stage and histopathological differentiation were statistically significant. The colon cancer showed better prognosis compared to the rectal cancer.

김상철,이동호,최현민,김창훈,남영진,홍춘표 대구대학교 정보통신연구소 2008 情報通信硏究 Vol.5 No.1

This paper presents a high-performance elliptic curve cryptographic processor over GF(2m). The proposed design adopts L&oacute;pez-Dahab Montgomery algorithm for elliptic curve point multiplication and uses polynomial basis for GF(2m) field arithmetic operations. We select m=163 which is the smallest value among five recommended GF(2m) field sizes by NIST. The proposed elliptic curve cryptographic processor consists of host interface, data memory, instruction memory, control, and ALU. We simulate the proposed design using Xilinx XCV2000E hardware platform. Simulation result, we can see that our design is high flexibility and requires significantly less hardware resource compared with the previously proposed hardware implementation. 본 논문에서는 GF(2m)상의 고속 타원곡선 암호 프로세서를 제안한다. 제안한 암호 프로세서는 타원곡선 정수 곱셈을 위해 L&oacute;pez-Dahab Montgomery 알고리즘을 채택하고, GF(2m)상의 산술 연산을 위해 다항식 기저(Polynomial Basis: PB)를 이용한다. 본 논문에서 구현한 타원곡선 암호 프로세서는 m=163을 선택하였으며 NIST(National Institute of Standard and Technology)에서 권고하는 5개의 GF(2m) 필드 크기 중에서 가장 작은 값이다. 제안한 암호 프로세서는 Host Interface, Data Memory, Instruction Memory, Control, AU(Arithmetic Unit)로 구성되어 있으며 Xilinx XCV2000E 하드웨어 플랫폼으로 시뮬레이션을 한다. 그 결과 제안된 암호 프로세서는 기존의 연구 결과에 비에 높은 확장성과 낮은 하드웨어 복잡도를 가진다.
