위키는 협동하여 글쓰기를 위한 상호작용적 도구로 활용할 수 있는 웹 기반의 하이퍼텍스트 저작 시스템이다. 위키는 프로토타입 개발을 위한 동료 간의 토의와 협업 도구로 사용되고 있으며, 일반적으로 누구나 자유롭게 정보와 지식을 편집할 수 있는 지식 공간으로 웹을 기반으로 하는 동적 프로그래밍이라고 할 수 있다. 본 연구는 이러한 키의 아이디어를 바탕으로 초등학교 쓰기 학습에서 필요한 학습자들의 협력적 의사소통과 의미구성을 효율적으로 지원하는 위키의 도구적 특성과 학습자 간,학습자와 교수자 간의 시·공간적 제약을 극복할 수 있는 상호작용적 교수·학습을 구성하는 위키식 협동학습 환경으로 협동적 글쓰기를 위한 학습모형을 개발하는 것이다. 이러한 목적을 달성하기 위하여 위키 기반 협동적 글쓰기 학습 모형에 내재되어 있는 핵심 가치와 핵심 학습 활동을 분석하고, 협동적 글쓰기 학습의 핵심 학습활동을 촉진시켜 주는 지원 전략을 도출하였다. 뿐만 아니라 위키 기반 협동적 글쓰기 학습 모형의 초안을 구안하고, 전문가 검토를 통한 수정을 거쳐서 최종적인 위키 기반 협동적 글쓰기 학습 모형을 개발하였다. The purpose of this study is to develope Wiki based learning models for collaborative writing by integrating the features of Wiki to collaborative writing skills. The first research task of this study is to derive the inherent core values and learning activities from Wiki based collaborative learningmodels. Second task is to derive support strategies to promote learning activities (writing strategies, cooperative learning, blending learning) of these models. Thrd task was, based on the extracted core values, core learning activities, and support strategies, to make the draft of learning models of collaborative writing. After modifications by expert reviews, suggested the final Wiki based collaborative learning models. The methods and procedures of this study is below. First, investigated and analyzed the situation and problems by the law questionnaire surveys, and then extract key elements and learning activities from Web using case studies and previous researches of model development. Secondly, construct the daft of the learning models. Finally,revised them consistently by experts review.

Objective : To investgate patterns of serial serum interleukin-6(IL-6) concentrations after initial successful cardiopulmonary resuscitation, and to access differences in serum IL-6 concentrations in patients with Cerebral Performance Category(CPC, 1-2) and CPC(3-5) at the 5th day after cardiacpulmonary resuscitation(CPR). Methods : We studied prospectively 12 patients with spontaneous circulation after cardiopulmonary resuscitation. Venous blood samples were taken 2, 4, 12, 24, 48 and 72 hours after restoration of spontaneous circulation to measure serum IL-6 levels by the enzyme-linked immunosorbent assay. Results : Serum IL-6 concentrations in the severe neurolgically disabled group(CPC, 3-5) were significantly increased at 2, 24 and 48 hours after restoration of spontaneous circulation compared with the less neurolgically disabled group. Also, serum IL-6 concentrations in the severe neurolgic disabled group showed dual peak at 4 and 24 hours. Conclusion : Our study demonstrates significant increase of serum IL-6 in patients with CPC(3-5) after successful cardiopulmonary resuscitation and the significant correlation between early increase of serum IL-6 and poor neurologic outcome. It suggests that early increase of serum IL-6 can be used as a prognostic marker after successful cardiopulmonary resuscitation.

We have carried out the field compaction tests in the site in which the high rock fill embankments are going to be constructed about 25m in height, to examine the effect of the soil fraction to the total embankment materials which are the mixture of rock fills and soils on the degree of field compaction. We have made four sets of in-situ concrete boxes of the size of 1.5m×1.5m×0.6m to obtain the maximum dry density of total embankment materials after compacting by using a 10-ton vibrating tamping roller. We have found, as a result, that the optimum passing number of the roller to yield the 90% of relative compaction economically attainable has appeared to be 8 passes, and that the percent of the soil fraction to the total embankment materials to yield the 90% of relative compation in the field has appeared to be 41.78% by weight.

This study was conducted to establish an individual identification system comprising of 19 microsatellite markers located on different bovine autosomes. The markers were typed on 257 animals from five cattle breeds. In total, 112 alleles were detected from the genotyping of 19 microsatellite markers. The average heterozygosities ranged from 0.292 to 0.824 and the polymorphic information content (PIC) ranged from 0.274 to 0.817 in Hanwoo. We found that there were differences in allele frequencies in Hanwoo when compared with other cattle breeds. The calculated cumulative power of discrimination (CPD) was 99.999% when nine microsatellite loci were used for analysis in the individual identification system. Also the matching probability, the probability that two unrelated animals would show the same genotypes, was estimated to be $0.44{\times}10^{-9}$. Therefore, the nine markers used in this study will be used for individual identification in two million Hanwoo individuals.

김학두(Hak Du Kim),김진석(Jin Suk Kim) 한국정보과학회 2002 한국정보과학회 학술발표논문집 Vol.29 No.2Ⅰ

이질적인 계산자원들로 구성된 환경에서 독립적인 작업들을 스케줄링하기 위한 최적의 방법을 찾는 것은 NP-Complete 문제로 알려져 있다 [4]. 현재까지 이 문제를 풀기 위한 다양한 휴리스틱 방법을 사용하며 동적 스케줄링 시기에 따라 온라인방식과 배치방식으로 나누어진다 [1, 12]. 본 논문에서는 새로운 스케줄링 알고리즘을 제안하였으며 제안된 스케줄링 알고리즘의 성능이 기존의 스케줄링 알고리즘의 성능보다 뛰어남을 실험을 통하여 보였다.

Genetic Relationships of Cattle Breeds Assessed by PCR-RFLP of the Bovine Mitochondrial DNA D-loop Region

Yoon, Du Hak,Lee, Hak Kyo,Oh, Sung Jung,Hong, Ki Chang,Jeon, Gwang Joo,Kong, Hong Sik,Lee, Jun Heon Asian Australasian Association of Animal Productio 2005 Animal Bioscience Vol.18 No.10

To investigate the genetic relationships among various cattle breeds, bovine mtDNA D-loop region was used in 411 animals of 18 cattle breeds, including 8 Asian Bos taurus, 7 European Bos taurus, 1 Asian Bos indicus, and 2 African Bos indicus. The size of amplified PCR products from mtDNA D-loop region was 964 bp and the products were digested by 15 different restriction enzymes. Two different band patterns were identified in eight restriction enzymes (BstXI, Hae III, Msp I, Apa I, Taq I, Alu I, BamH I, EcoN I) and the rest of restriction enzymes showed more than 3 different band patterns among which Apo I and MspR9 resulted in 7 different restriction patterns. The genotypes, number of haplotype, effective number of haplotype, and degree of heterozygosity were analyzed. Based on all the PCR-RFLP data, different haplotypes were constructed and analyzed for calculating genetic distances between these breeds using Nei's unbiased method and constructing a phylogenetic tree.
