Traffic lights contain very important information for safety driving. So, the delivery of the information to drivers in real-time is a very critical issue for advanced driver assistance systems. However, traffic light detection is quite difficult because of the small sized traffic lights and the occlusion in real world. In this paper, a traffic light detection method using modified color based saliency map and morphological information is proposed. It shows 98.14% of precisions and 83.52% of recalls on computer simulations.

위암은 국내 암발생 및 사망률의 상당 부분을 차지하고 있으며, 이러한 조기 위암의 발견은 치료 및 예후에 있어서 아주 중요하다. 본 논문에서는 조기 위암의 진단을 위해 위 내시경 영상에서 색상 변화를 이용해 이상 부위를 검출하여 검사자에게 조직적인 정보를 제공하는 시스템을 제안한다. 어느 정도의 진행이 이루어진 염증과 암은 쉽게 판단할 수 있지만, 조기의 염증이나 암의 경우에는 주의 깊게 보지 않는 경우에는 병변의 진단이 쉽지 않다. 본 논문에서는 위 내시경 영상을 IHB 채널로 변환시키고 조명에 의해 발생하는 잡음을 제거하며 자동으로 암 의심 영역을 검출하여 검사자에게 제공하거나 검사자에 의해 설정된 영역에 대한 조직적인 표면 정보를 제공한다. 본 논문의 연구는 추출된 이상 부위가 암을 확진할 수 없지만, 인간이 쉽게 인지하기 어려운 이상부위(암 의심 영역)를 추출하여 검사자에게 주의를 요구함으로써 일 처리를 줄이고 부과적인 정보를 제공한다. 그리고 검사추가 지정한 영역에 대해서도 조직적인 정보를 제공한다. 제안된 위 내시경 영상 분석 방법의 효율성을 확인하기 위해서 실제 내시경 영상들을 대상으로 실험한 결과, 제안된 방법이 위 내시경 영상 분석에 효율적임을 확인하였다.

The purpose of this study was to construct a hypothetic model for the influential theoretical variables for the facial cosmetic resurgery intention of female college students with cosmetic surgery experience and to examine the compatability of the re-surgery intention model with real data. The subjects in this study were 320 selected female college students who had undergone cosmetic surgery. After a survey was conducted from July 15 to September 20, 2014, the answer sheets from 300 respondents were gathered, and the answer sheets from 295 respondents were analyzed except for the five ones that included uncertain answers. As a result, it's ascertained that cognitive dissonance was under the direct influence of post-surgery satisfaction with appearance, self-esteem, subjective norm and lookism.. Self-esteem, subjective norm and lookism had a direct impact on resurgery intention, and self-esteem and lookism affected resurgery intention both in direct and indirect ways through the medium of cognitive dissonance. The findings of the study are expected to provide useful information on the development of nursing intervention programs geared toward promoting physical and mental health.

Earnings management is a collection of management decisions which firms do not report the true performance. Many prior studies suggest that earnings management could be the results of either managerial earnings management or manager's private information for future performance. This study attempts to delve into the fundamental implications inherent in earnings management by analyzing how earnings management affects future firm performance in public institutions. If discretionary accruals as a measurement of earnings management embrace manager's private information, it will have a positive effect on future performance in succeeding period. In contrast, if discretionary accruals embrace manager's opportunistic earnings management, it will have a negative effect on future performance in succeeding period. Empirical findings are summarized as following.: Earnings managements are negatively associated with future firm performance for all succeeding period. This negative relationship continues for all succeeding period. The overall results can be serve as a evidence that the discretionary accruals capture opportunistic earnings management on average.

Some appearances of the result images from the researches on NPR(Non Photorealistic Rendering) look like contrary to the attributes of the real painting. As they are based on only the technical approach rather than the aesthetic and accurate analysis of the real painting which they modeled. Therefore the purpose of this paper is the abstraction of the exact features from the related real painting, the redefine of them applicable to the process, and the embodiment of the painterly NPR algorithms. This paper modeled the Impressionism which were originated in the France at the late nineteenth century. Accordingly, at first, I analyzed the general features of oil paintings and Impressionism paintings, and according to this analyses, I adjusted them to engineering elements(the direction, length, width, texture and speed of stroke, the edge and region of object, depth information and color etc) and programmed. I emphasize the importance and potentiality of the collaboration of artist and technician in the NPR research through the results in this paper.

It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.

The purpose of this paper is to investigate which the nature of teacher behavior affects the learning flow in the context of military education. Empirical results show that the leadership of the nature of teacher behavior has a significant effect on three factors of learning flow (flow experience, transformation of time, concentration on task). In addition, the pace of class of the nature of teacher behavior is significantly related to the transformation of time and the concentration on task, and the sense of humor of the nature of teacher behavior significantly affects the concentration on task. The findings provide practical implications on how a military education institution strategically employes the leadership, the sense of humor, and the pace of class in an attempt to select and train instructors.

In this paper, we design a environment in computers and mathematics education. For this purpose, we study two different points of view about relations between computers and mathematics education. As theoretical background, we also study constructionism and microworld. Next, we introduce functionization as a basic principle for computers and mathematics education. The concept of functionization focuses on the variation of mathematical objects, and it is a basic concept of both mathematics and computer science. We consider the concept of functionization as a paradigm for the research and practice of the computers and mathematics education. We also present the concept of functionization as a principle for designing a computer environment. Finally, we use the concept of functionization to integrate two famous microworlds, LOGO and DGS by introducing such objects as tiles and folding nets. Combining LOGO and DGS, we design a new microworld that can be used under the internet environment. We present tiles and folding nets to introduce how the concept of functionization is used to design a new microworld and to integrate two microworids.

The Common Core States Standards was developed by building on the best state standards in the U.S.; examining the expectations of other highperforming countries around world; and carefully studying the research and literature available on what students need to know. The Common Core States Standards for Mathematics are reshaping the teaching and learning of mathematics in California classroom using the California Common Core States Standards for Mathematics(CA CCSSM). The aim of this study is to observe CA CCSSM. The CA CCSSM were established to address the problem of having a curriculum that is 'a mile wide and an inch deep'. And it have two types of standards. One is standards for mathematical practice which are the same at each grade level, the other is standards for mathematical content which are different at each grade level. This study focused on standards for mathematical content, in particular, on Geometry domain in elementary level, using Mathematics Framework for California Public Schools.
