The purpose of this study is to investigate the relationships between cognitive conflict and students' causal attributions and to find out what kinds of attributions affect successful resolution of cognitive conflict in learning physics. Twenty-nine college students who attended a base general physics course took an attribution test and a conceptual pretest related to action and reaction concept. Of these, twenty students who revealed alternative conceptions were selected. They were confronted with a discrepant demonstration and took part in the cognitive conflict level test, a posttest, and delayed posttest. Those students who experienced high levels of cognitive conflict were selected and interviewed to find out what kinds of attributions affect resolving the conflict. When confronted with the discrepant event, the students who attributed success outcomes to "effort" experienced higher levels of cognitive conflict than those to "task difficulty." However, those students who revealed high levels of cognitive conflict and attributed success outcomes to effort did not always produce conceptual change. They had different perspectives on effort and conducted different effort activities to resolve the cognitive conflict. In addition, these effort activities appeared to include their motivational beliefs, metacognitive and volitional strategies. The results of this study indicate that in order for the conflicts to lead to change, students need to have the perspective on effort implying the use of the self-regulated learning strategy and to conduct effort activities based on them. Beyond cold conceptual change, this article suggests that there is a management strategy of cognitive conflict in the classroom context.

본 논문에서는 중복 구조 시스템을 이용하여 각 프로세서에서의 출력을 비교하여 효율적으로 고장을 탐지하고, 체크포인팅 기법을 적용하여 과도 고장뿐 아니라 영구적 고장을 극복하기 위한 방법을 제안한다. 매 체크포인터에서는 각 프로세서로부터의 출력과 과거 체크포인터에 저장된 데이터를 불러와 서로 비교한 후 과거 체크포인터로 회귀할지 태스크의 수행을 계속 수행할지 결정한다. 과도 고장과 영구 고장이 발생할 수 있는 상황에서 제안된 체크포인팅 기법을 탑재한 중복 구조 시스템을 마코프 모델을 이용하여 모델링한다. 마코프 모델로부터 실시간 태스크가 데드라인 이내에서 성공적으로 수행을 끝낼 확률을 계산하고, 이 확률식을 이용하여 중복구조 시스템에 탑재할 체크포인터 구간을 최적화한다. 최적화된 체크포인터 구간은 태스크의 성공적 수행 확율을 최대화 하도록 선정하였다.

Purpose: The purpose of this study was to determine effects of posttraumatic growth, aging anxiety, and spirituality on successful aging in late middle-aged women. Methods: Participants were 128 late middle-aged women. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and hierarchical multiple regression with SPSS WIN 23.0 program. Results: Results showed that significant factors influencing successful aging were spirituality and monthly income. This regression model explained 21.4% of the variance in successful aging. Conclusion: These results provided the basic data for establishing an intervention strategy to increase the level of successful aging of middle-aged women. In addition, the results suggested that development of a nursing intervention program is in need.

This paper will examine some past and current issues concerning the Republic of Korea's national strategy, focusing predominantly upon how the ROK should respond to the urgent maritime-oriented strategy highlighted by the recent developments and achievements of national prosperity achieved during last three decades and identify some of successful cases in East Asia. Some consideration will also be given to more general emergent issues of trends and developments of East Asian countries which might affect to define the ROK's future national strategy in the context of its national grand strategy to enhance national interests and prosperity. ROK is especially dependent upon open Sea Lanes of Communication (SLOC) and its national security emphasizes the sea as the medium of geopolitical and geo-economic development, given the sea known as core geographic option remains that ROK is an important maritime power, ranking the world-level nation in term of GDP, sea-borne trade, container processing capability, shipbuilding capacity and so on. It should be apparent, therefore, that ROK's national strategic development depends upon the relationship between its peninsula geography and its national development based on sea-borne economic growth and its maritime-oriented future national strategy will be the best option to maintain its national development and economic prosperity.

본 연구에서는 앞으로 있을 한 중 FTA협상 추진 전략을 중국의 낮은 수준의 FTA 체결 선(先)제의에 대한 우리나라의 최적 대응전략 측면에서 고찰하였다. 국제협상 분석 게임모델 중 비협조게임의 기본 모형인 죄수의 딜레마 게임을 기본 틀로 하여 Putnam의 2단계 게임 론을 활용하여 결론을 도출하였다. 향후 한 중 FTA 추진의 전략적 기본원칙은 정부가 주장하는 높은 관세양허 수준의 포괄적 FTA보다는 비록 경제적 효과가 다소 떨어지더라도 가능한 빠른 시일 내 '중간 수준'의 FTA(포괄적이나 전반적으로 낮은 관세양허 방안)를 시작하는 정책을 추진함이 바람직 할 것으로 결론지었다. 이러한 관점에서 한 중 양국이 상대국으로부터의 수입액 중 일정 비율, 가령 70-80%에 해당하는 품목에 대해 협상개시와 함께 관세를 내리는 조기수확 프로그램(EHP: Early Harvest Program)을 활용하는 전략도 한 방법이 될 것이다.

In Schumpeterian competition, superior profit arises from successful innovation created by firm's R&D strategy. Such R&D strategy diverges as time passes. This study examines empirically the effects of diverged forms of R&D strategy such as technological assets, technological diversity, and technological similarity on firm performance in Korean pharmaceutical industry. With the financial and patent data of 96 firms for 14 years from 1994 to 2007, we measured variables. And then we performed panel analysis with 3 years lag between dependent variable and other variables. The result shows that firm performance increases as technological asset and technological diversification increase. But technological similarity positively affects on firm performance in opposition to our hypothesis. We interpret and discuss these results and highlight the theoretical and practical implications of our findings.
