As entering the Big Data age, utilization of Big Data is also increasing in the intellectual property sector. Meanwhile, the purpose of a trademark which distinguishes the source of the goods essentially is to enable the public to recognize the goods. Big Data technologies which is recently becoming a issue can be used as a tool to judge consumer's awareness of the trademark. It was difficult for judgment of trademark awareness through traditional ways. As a new way, survey methodology has bee received attention, and it was applied to the field of trademark law. However, various problems such as cost, time, objectivity, and fairness were observed. In order to overcome theses limitations, this study proposes new way utilizing big data analytics for judgment on consumer's awareness of the trademark. This new way will not only contribute to enhancing the objectivity of judging trademark awareness but also utilized to support for related legal judgments.

소프트웨어 신뢰성을 향상시키는 방법에는 소프트웨어 결함 허용기법 중에서 가장 객관적이고 정량적으로 평가받는 것이 NVP(N-Version Programming)기법이다. 이 기법에서 신뢰도를 추정하는 모델로 이항분포를 사용하는데 이 모델은 각 컴포넌트 신뢰도의 값들이 동일하다는 한계점이 있었다. 본 연구에서는 기존 모델의 한계점을 해결하기 위하여 NVP 신뢰도 분석을 위한 새로운 접근 방법으로 유전자 알고리즘(Genetic Algorithms)을 적용하였고. 또한 적용 모델과 기존 모델을 서로 비교 검토하였다. 그 결과 전체시스템 신뢰도를 일정 수준이상 유지하면서 각 컴포넌트 신뢰도의 값들을 최적화 할 수 있었고. 또한 비용을 최소로 하는 최적의 수를 추정할 수 있었다. 그리고 적용 모델과 기존 모델을 비교 및 평가하여 타당성을 증명하였다.

정보기술의 개발 및 도입을 위하여 많은 투자가 이루어지고 있으나 IT가치평가의 독특성과 IT가치의 다양성으로 계량적이고 객관적인 IT가치평가가 용이하지 않다. 이 연구에서는 IT의 가치를 평가하고 IT가치전략을 분석하기 위한 새로운 IT가치평가방법을 제시하고자 한다. 이 방법론은 경영 전반의 관리 및 성과 평가를 위한 Balanced Scorecard(이하 BSC)의 평가요소를 이용해 새로운 프레임워크를 제시함으로써 가능하다.

감성과학은 인간의 감성을 정성하고, 더 정량적으로 측정 평가하고 이를 제품이나 환경설계에 응용하여 보다 편리하고 안락하며, 안전하게 나아가 인간의 삶을 쾌적하게 하고자 하는 기술이다. 본 연구에서는 사상 체질론, 오행 체질론, 바이오리듬의 감성적 요소를 감성과학의 관점에서 고찰하고, 각 기질이나 상태별로 반응시간 측정기로 반응시간을 측정하고, 반응시간의 차이를 분산분석(ANOVA)을 이용 비교ㆍ분석하여 객관적으로 평가하고, 직무설계에 이용하고자 한다.

얼굴 인증에서 가장 보편적으로 사용되고 있는 주성분 분석(PCA . Principal Component Analysis)은 정면 얼굴과 같은 특징 패턴에 대해서 비교적 높은 성능을 보인다. 인식률을 떨어뜨리지 않으면서 데이터량을 줄일 수 있는 효과가 있어 클래스를 잘 축약하여 표현하기에 유용하다. 하지만 조명이나 표정의 변화에 대해서는 성능을 보장할 수 없다 이를 보완하기 위해 성분이 다른 클래스간의 분리가 수월하도록 선형판별분석(LDA Linear Discriminant Analysis)을 사용한다 LDA는 데이터의 양이 적을 때는 성능이 떨어지는 단점이 있다 그래서 PCA와 LDA를 융합한 기술을 사용하면 더 나은 성능을 얻을 수 있는데 Min, Max, Mean, Append, Majority voting방법 등이 이에 해당된다. 하지만 기존 연구에서는 제한적 데이터베이스에 대한 실험에 그쳐 실험 결과의 객관성이 부족했다. 본 논문에서는 정형화된 환경에서 여러 가지 데이터베이스를 사용해 실험함으로써 Min, Max, Mean 융합 알고리즘의 성능을 비교 분석한다. 융합 알고리즘이 언제나 좋은 성능을 내는 것은 아니지만 얼굴영상에서 조명이나 표정 등이 변화함에 상관없이 일정 수준의 인증율을 보장하고 있다.

In this paper, we proposed an image shaking index to evaluate the remote controllability of vision based unmanned vehicles. To analyze the usefulness of the proposed image-shaking index, we perform subjective tests using a virtual unmanned vehicle driving simulator. The developed driving simulator consists of a real-time multibody dynamic software of the unmanned vehicle, a motion simulator, and a driver console. We perform dynamic simulations to obtain the motion of the unmanned vehicle running on the various road surfaces such as ISO roughness level A~E roads. The motion of the vehicle body is reflected in the motion simulator. Then, to enable remote control operation, we offer to operators the image data that was measured using the camera sensor on the simulator. We verify the usefulness of the proposed image-shaking index compared with subjective index provided by operators.

According to Ferber (1988), philosophy of science considerations are particularly important for an area like consumer research that seeks to be interdisciplinary. The fact that the topic is studied by so many disciplines with different research traditions immediately raises the question of how one evaluates the (often conflicting) knowledge claims of its various practitioners. Closely related to this is the issue of whether it is even possible to study the topic in a truly interdisciplinary manner or whether a multidisciplinary approach is worth trying. In fact, this issue has triggered heated debates on positivism and relativism in consumer research and a significant number of consumer researchers, though majority of them still resorts to the traditional positivist paradigm, has rejected the tenets of positivism and has turned instead to relativism as the emergent paradigm for knowledge generation. The purpose of this paper is to elaborate on the possibility of eclecticism between positivism and relativism in consumer research. However, self-justifying system of each research camp let any comparison or attempt to reconcile regress to the questioning of philosophical assumption, "Objective reality does exist?", which can not be resolved. As Kuhn (1970) noted, philosophy of science may be chosen for reasons that are ultimately personal and subjective. Therefore, the possibility of eclecticism may be reserved. Rather, complementarity of each research practice can be suggested to make consumer research achieve holistic disciplinary status. Both camps can get nowhere by challenging respective philosophical underpinnings but can advance knowledge on substantive and methodological domains by complementing each other.

The purpose of this research propose the improvement of the visual arts educational environment according to the previous studies that is visual arts education have effect on the students' creativity and their Psychological Aspects. In addition, This study provide the preceding material in terms of the future quality of the environment and curriculum for public schools and indicate the advantages and disadvantages of each design space as examining what is needed aspect of the art connectivity. Research method is to investigate the domestic and International public school's visual arts education environment aspects of the facility and space status for safety and activity. As well, method is that it will find out how the program is being conducted in any part of the local culture. Art Education is not the non-intrusive training, but the series of processes going to work together and solve problems through participation of the creative experience based on the art motif. Therefore, it will be a well-supported guideline to establish the art educational environment.

We examine the effects of the self-reported subjective and the objective health indexes on work compensations. The compensations consist of monetary factors, such as wages, and non-monetary factors reflecting job risks such as the workplace accidence. The wages and workplace injuries are clearly affected by gender and age differences as the subjective and objective health factors of elderly workers are combined with physical and systematic work environments. Mental health problems such as work depression are more serious especially for high income elderly groups. The elderly workers experienced with physical problems and chronic illnesses are led to the decrease in wages and the increase in safety accident risks at work sharply. Therefore, we need to provide supporting services, retirement planning designed by companies, supported by the government enhanced risk working conditions and the weakness on protecting jobs.
