To establish a statistically reliable sampling strategy for serological surveillance of classical swinefever (CSF) in Korea, antibody test data from CSF surveillance conducted during year 2005 were analyzed.The most appropriate sampling method was determined to be stratified multi-stage random sampling strategy,in which the primary sampling unit is a pig farm and the secondary are the pigs by the strata of breedersand finishers in the selected farm. The optimum sample size was 5 to 19 including 1 to 2 breeders accordingto the number of pigs in the farm. The optimum sampling strategy demonstrated in this study was veryFindings of our study provide practical guidelines for surveillance of herd immunity level to CSF in Korea.

본 논문의 목적은 동북아시아에서 변화하는 물류환경에 우기나라가 능동적으로 대처하여 명실상부한 물류중신 국가가 되기 위한 전략의 적합성을 탐색하는데 있다. 전략은 동북아 물류환경에 대한 SWOT 분석에 의거하여 균형성과모형(BSC)의 재무적 관점에서 도출하였다. 이러한 재무적 관점의 전략의 적합성을 검정한 결과, 우리나라가 2l세기에 동북아 물류중심국가가 되기 위해서는 보다 효과적인 물류성과를 창출할 수 있도록 예산의 선택과 집중전략을 극대화하는 물류정책을 수행하여야 하는 것으로 나타나고 있다.

다양한 산업에서 강조되고 있는 정비의 중요성은 각 분야에 다양한 정비전략을 적용하도록 만들었다. 해양산업 역시 그에 따른 정비전략의 변화가 있었으나 타 산업 대비 그 속도가 느려 실제 적용이 되지 않은 채 과거 시행되고 있던 방식을 유지하는 경우가 많다. 특히 선박은 기존에 행해왔던 방식의 정비전략을 사용하고 있는 편이며 해상의 조건에서 선박은 새로운 정비전략의 개발을 필요로 하고있다. 이에 선박예지정비모델은 기기의 정비가 필요한 시점을 예지하여 조치 할 수 있는 정비전략으로서 선박이 항해 중에 처할 수 있는 정비 관련 위험요소들을 줄여 주는 모델이다. 본 연구는 선박예지정비모델의 개발을 위한 연구 중의 하나로서, LNG선박 입거사양서의 텍스트 데이터 분석을 통한 결과를 원문의 내용을 바탕으로 해석해보았다. 공통된 정비항목 조합을 도출하여 선박 내 다른 기기들 사이에 작용하고 있는 상호연관성을 발견하고 이를 앞으로 개발될 선박예지정비모델에 적용하고자 한다.

이 연구는 과학 텍스트 읽기 전략으로 의미지도가 고등학생의 추론적 이해에 미치는 영향을 알아보는 것을 목적으로 하였다. 이를 위해 고등학교 3학년 과학중점반 2개 학급 학생 46명을 대상으로 한 학기 동안 의미지도 읽기 전략을 활용하여 8개 주제의 과학 텍스트 읽기 수업을 실시하였다. 의미지도 읽기 전략이 과학 텍스트의 추론적 이해에 미치는 영향을 알아보기 위해 학생들이 작성한 사전·사후 읽기 능력 검사지를 비교 분석하였다. 추론적 이해 변화를 알아보기 위해 추론적 이해 분석틀을 개발하여 추론적 이해 수준을 분석하였다. 추론적 이해 변화를 분류하기 위해 추론적 이해 분석틀의 세부 항목인 3개 항목의 수준을 점수로 환산하였다. 학생들의 추론적 이해 변화 분석 결과는 의미지도 읽기 전략 수업이 고등학생의 추론적 이해 변화에 영향을 미쳤으며, 특히 추론적 이해의 하위 유형 중 교량 추론과 정교화 추론에 영향을 미치는 것으로 나타났다.

Following a microgenetic design, this study was analysed the characteristic and the change of classification strategy that appear in college students' classification activity. The 4 tasks were developed for classification activity; a shell as a familiar real things, an animal fossil as a unfamiliar real things, a snow flake as a familiar picture cards and galaxy as a unfamiliar picture card. Achieved study to 6 college students who major in elementary education. Data were collected by interview with subjects, subject's classification schema, investigator's observation of subject's activity, and videotaped that record subject's subject classification process over an extended period of 6 times. Result proved in this study is as following. In the 6 times of the data collection procedures, a strategy F identifying concrete attribution of classification objects and a more detailed strategy X3 combining qualitative, spatial and dimensional attribution were found and more frequently used in both groups of college students which reported a classification process and did not report the process. While discovery and absorption of both a concrete classification strategy and a detailed classification strategy were rapidly developed in the reporting group, they were gradually developed in the non-reporting group. In addition to this, as the data collection procedures were progressing, the college students were familiar with change factors of classification tasks and in the case of pictures the classification strategy showed more desirable changes.

The study aims to answer why the previous studies find the positive or insignificant effect of the CEO's abilities on firm performance. Using 34,285 CEO-firm-year panel data from the U.S. publicly traded firms drawn from the BoardEx and EXECUXOMP database during from 1992 to 2014, the results show that the fit of the CEO's generality or specialist ability with firm strategy matters on firm performance and risk. This study computes a discrete STRATEGY composite measure to construct firm strategy types, such as Prospect or Defend and use CEOs' résumés to construct an index of general skills that are transferable across firms and industries. The results find that generalist CEOs are more suitable for prospectors than specialist CEOs. Firm performance is much better when specialist CEOs work for Defenders. Although the firm performance is better too for the generalist CEOs who fit for the Prospect strategy, the firm's risk is up too. The result suggests that firms need to consider their chosen business strategy to recruit and select CEOs Our findings provide direct evidence that the match between CEO's ability and the firm's strategy is crucial to firm performance and risk.

The purpose of this study was to investigate the type of classification criterion and the characteristic of classification strategy that appear in pre-service elementary teachers' classification activity. The 4 tasks were developed for classification activity; button as a real things that attribute is prominent, shell as a real things that attribute is less prominent, snow flake as a picture cards that attribute is prominent, and galaxy as a picture cards that attribute is less prominent. The 5 college students who major in elementary education were selected. Data were collected by interview with participants, participants' classification recording paper, investigator's observation of participants' action observation, and videotaped that record participants' subject classification process. Result proved in this study is as following. First, pre-service elementary teachers used 4 qualitative classification criterion of feature, random field, image and secondary property, and used 2 dimension classification criterion of space and quantity. They used single quality classification criterion or combining dimension classification criterion in classification activity. Second, pre-service elementary teachers have classification strategy that apply each various classification criterion, and also classification strategy are different according to subject, but discussed that "anchor" and "priming effect" are important for effective classification. Result of this study is expected to contribute classification research and classification teaching program development.

This study is aimed to prepare the promotion strategy to spawn snow crab resources and create their habitats using SWOT-AHP analysis. Currently, the creation program of spawning and habitat ground (CPSH) of various fisheries resource is a continuing process, however, none of these CPSH can be labeled as being effective in Korea. In order for CPSH to be effective, it must be planned systematically. Therefore, it is necessary for establishing promotion strategy on the CPSH. SWOT-AHP analysis is used to improve explanation ability of SWOT analysis. In this research, we suggested three strategies and 15 implementation plans of the CPSH using SWOT-AHP analysis. It is expected that the economic feasibility, ecosystem and recovery of fisheries resources will improve significantly. Consequently, to increase the performance of CPSH, it is necessary to focus on the developing an efficient and executive promotion strategy on the CPSH.

We developed animation-based environmental teaching program using empathic learning strategy in order to motivate elementary school students' willingness to practice environmental-friendly behavior and applied it to elementary school students. The subjects were 56 fourth graders, who were divided into the experimental and controlled groups. Experimental group was taught with animation programs using the empathic learning strategy and controlled group took typical classes. There was significant difference between experimental and controlled groups(p<.05) in terms of environmental practice willingness. When examining students' environmental-friendly recognition, this study showed positive result that they were more interested and motivated in the learning process. Thus, it concluded that the environmental animation program using empathic learning strategy was an effective teaching method. It showed that it was more effective to improve environmental knowledge and motivates students to actively participate in instructions and to concentrate on educating materials.
