  • 본 연구에서는 MPSOC(Multiprocessor System-on-Chip) 환경의 소프트웨어적인 측면을 주 연구대상으로 하였고 범용 전문 프로그래머들에게 병렬 애플리케이션 프로그래밍을 위한 패턴언어를 제공한다면 병렬처리의 장점을 호소할 수 있을 것으로 보았다. 특히 자체적인 분류에 따른 Data, Tasks, Data flow 모델을 선별하고 그중 CUDA와 HOPES를 경험한 대상으로 Petri Net을 활용, 그들의 숙련도를 확인하는 과정을 포함한다. 각 영역의 숙련 정도, 서로 다른 모델에 대한 이해도를 실험을 통해 검증하였다. 페트리넷은 병렬프로그래밍의 설명에 용이한 모델로 특히 동시성과 병렬성을 설명하는데 탁월한 모형을 제시 할 수 있었다. 실험대상자들에게 페트리넷에 관한 4시간의 선행학습을 시킨 후 56명에게 실험을 실시하여 독립표본 t-검정을 수행했다. 비록 설정된 두 가지 가설이 지지되지 않았지만, 각 영역에서의 숙련자들이 Tasks 중심 혹은 Data 중심의 모형을 얼마나 상호 이해하는가를 판단 할 수 있었다.

  • Objective: This study provides strategies of how to effectively convert an invention, created at universities or government-funded research institutes, into a strong patent with the clear understanding of its unique technological characteristics. Background: Regardless of the amount of research funds available in our country and the decent number of intellectual property rights created using the funds, there was a deficit of more than KRW 6 trillion in the technology trade balance related with intellectual property rights in the year of 2014. One of the reasons was that the vast number of patents that were being produced by universities or by government-funded research institutes were merely performance-based patents, namely, so called "patents for patents". Another reason is that developed technology from research and development could not be transformed into a strong patent right properly due to the lack of related knowledge. Method: After reviewing various references mentioned on the patent strategies, the definition of a strong patent and the strategies of producing a strong patent for an invention drawn out from research performance will be supplied. Results: To produce a strong patent right at universities or government funded research institutes, one should use strategies for strong specifications, strategies of product patents and method patents, strategies of patent portfolios, strategies of know-how, strategies of inventions defined by numerical limitation and strategies of parameter inventions for a more strategic approach. Conclusion: Strong patent rights will be produced with the use of effective patent strategies provided in this study. Application: It is estimated that the results of this study will aid the establishment of strong patents for inventions developed by research performance at universities or government-funded research institutions.

  • 본 논문에서는 국민연금과 주요국 공적연금에서 사용되는 재정평가지표들을 고찰해 보고 국민연금 재정계산 시 보완 및 적용 가능한 재정평가지표로 수정적립배율, 보험료충당률, 기금충당률을 제안하였다. 수정적립배율은 평가시점에 보유한 적립기금으로 장래 지출을 감당할 수 있는 제도유지 기간을 측정하며 기금의 적립 수준에 대한 의미 있는 해석을 가능하게 한다. 보험료충당률과 기금충당률은 국민연금의 지출 재원을 보험료수입과 적립기금으로 구분하여 재원에 따른 지출 충당 비율을 측정한 지표이다. 평가기간 동안의 재정상태를 요약하여 나타내며 재원의 적절성에 대한 정보를 제공해 준다. 다양한 재정평가지표의 활용은 재정상태 평가에 대한 신뢰도를 높이고 이해를 돕는데 기여할 것이다.

  • The purpose of this study was to investigate what elementary teachers know about students' science misconceptions and how the teachers plan for and address their students' misconceptions in instruction. The sample included 61 teachers who participated in a teacher training program irrelative to science education. A questionnaire into which Gomez-Zwiep's semi-structured interview questions was transformed was used to examine the teachers' understandings of definition, origin, examples, and so on of science misconceptions, and their instructional strategies for addressing their students' misconceptions before and while instruction. The results showed that many teachers (about 60%) did not have appropriate understanding of students' misconceptions, that the majority of the teachers (about 75%) did not consider misconceptions at all before teaching science lessons, and that almost all the teachers (about 90%) did not know particular strategies specifically designed for misconceptions.

  • Recently, various researches in respect of the positioning technologies using satellites and the other sensors have made location-based services (LBS) more common and accurate. Consequently, concern about position information has been increasing. However, since these positioning systems only focus on user's position, it is difficult to know the user's attitude or detailed behaviors at the specific position. It is worthy to study on how to acquire such human attitude or behavior, because those information is useful to know the context of the user. In this paper, the sensor unit consisting of three dimensional accelerometer was attached to human body, and autonomously measured the perpendicular acceleration of ordinary human behaviors including activity modes such as walking, running, and transportation mode using transportation such as a train, a bus, and an elevator. Subsequently, using the classified measurement results, the method to identify the human activity modes was proposed.

  • RNA silencing has had a large impact on biology in general, as well as on our understanding of plant-pathogen interactions, especially interactions between plants and viruses. While most of what we know about the mechanism of RNA silencing was deduced in the last 12 years, many of the interactions between plants and viruses, as well as virus-virus interactions in plants, which we now know are manifestations of RNA silencing, were the subject of decades of work from numerous laboratories. These laboratories were examining the nature and extent of phenomena such as recovery from infection, the formation of dark green islands resistant to re-infection, synergy between unrelated viruses and cross-protection between related viruses, all first described in the late 1920s. In this review, the relationships between these phenomena and their place in the defense mechanism we call RNA silencing will be described, to show how they are all linked.

  • Assessment can be defined as any method used to understand the current knowledge that a student possesses. Assessment may influence decisions about grades, placement, instructional needs, and curriculum. Therefore, the purpose of assessment is to identify how the students think and know, to diagnose the difficulties they face, and to reflect the result of assessment on teaching. But the traditional multiple-choice test failed to evaluate and teach higher-level thinking and problem-solving skills. In this context, performance assessment is being required as an alternative assessment to get better understanding about what the students can do as well as what they know. This article points out some weaknesses of traditional assessments, and comments on the theoretical background and necessity of performance assessment. And it presents more specific information about performance assessment and some examples. It is certain that performance assessment is student-centered and future-oriented. But performance assessment can't be the surest and best way of evaluating the students' abilities. We are just on the way of another experimental stage for improving teaching methodology. More supplementary analyses and further improvements are needed.

  • In these days, an individual is evaluated by his or her credit. So, it is very critical for an individual to know his or her credit rating and then to try to improve the credit rating. But, there are few services to analyze credit status for an individual and inform the person of the credit. In fact, it could be impossible to let a person know how to improve his or her credit rating. Against this backdrop, we research on a credit management model to analyze credit status of an individual rapidly and propose individual-customized method to improve the credit rating. We set up the model and design it in detail. This servie would certainly make it convenient for an individual to retrieve credit rating and improve it.

  • FMEA is a widely used technique to assess or to improve reliability of products at early stage of design and development. In order to implement FMEA effectively, it is important to utilize knowledge or technical know-hows. However, that is very difficult. In fact, if information on the failure modes is enough, it is important to consider a counterplan to eliminate critical failure modes. If engineers do not have such information, however, it is more important to know what failure modes of the component under consideration would undergo. This means that the purposes of performing FMEA varies according to the situation. Therefore, we need different kinds of FMEA charts to meet those purposes. This paper proposes two FMEA charts: one is suitable for detecting potential failure modes and the other is for product improvements.
