This paper focuses on a sociologic approach, the theory of planned behavior (Ajzen 1991) and a sociolinguistic field, the language shift (Fishman 1991, Crystal 2000). It describes the theoretical background of language shift and briefly mentions the history of Hungarian language and Romanian language contacts. After presenting language use of the Hungarian minority students and explaining the theory of planned behavior, it turns to apply the theory of planned behavior to the language shift from the view of bilingual speaker(s). This paper wants to propose the application of the theory of planned behavior in language shift and open new perspective in bilingual research.

The purpose of this study is to investigate the effects of corporate mecenat activities, ultimately making more firmly established the theory of mecenat activities from the perspective of marketing. For the purpose, this researcher examined the motives of such activities and analyzed the current state and problems of those activities in Korea. In this study, the motives of corporate mecenat activities are largely classified into the improvement of corporate image, which is identified from the view of cultural investment, and direct corporate profits like tax favor, from the view of marketing. Regarding the effects of corporate mecenat activities, P. Kotler and J. Scheff suggested that in future, corporate supports to art would be the most remarkable part of marketing. In association, the Australian Foundation for Culture & Humanities and Arthur Andersen described the effects of corporate mecenat activities in form of cultural investment largely in terms of business, market and employees. In a similar vein, the Korea Business Council for the Arts classifies the effects of corporate mecenat activities largely into three, corporate legitimacy, market advantage and benefit to employees. In relation to corporate mecenat activities, now, the theory of mecenat which is established from the perspective of marketing is considered more persuasive than that which is provided from the perspective of philanthropy. For more corporate efficiency and effectiveness, in conclusion, it's needed to orient the theory of mecenat from the perspective of marketing.

This study categorized the viewpoint of cooperation between schools and communities into marketability and publicness, and the viewpoint of school education and lifelong education. The perspective of school education consider to utilize local resources for the growth of students. The lifelong education perspective sees cooperation between schools communities to support the learning of residents. While the marketability perspective pursues individual choices and diversity of opportunities, the publicness perspective focuses on ensuring citizens' right to learn and evenly distributing learning opportunities. From the point of view of school education, it seeks to utilize local resources for the growth and development of students, and in the view point of lifelong education schools are understood to support the learning activities of residents. Cooperation between schools and communities could be presented by categorizing them into private organization-led, educational authorities-led, and provincial authorities-led depending on the subject of the promotion. Recently, local governments and educational governments, schools and communities are developing to a stage where they cooperate to realize the vision of a educational community. For the cooperation between schools and communities the local community, cooperation between local government and educational government and the harmony between publicness and marketability are emerging as tasks.

AVM(Around View Monitoring) 시스템은 차량 주변에 대한 영상을 운전자에게 제공함으로써 안전 운전을 도와주는 시스템이다. 측면 거울이나 실내 거울을 통해서 볼 수 없는 사각 지대는 운전자의 안전 운행에 위협이 된다. 사각지대는 특히 후진 주행, 주차, 좁은 골목길 주행, 굽은 길 회전 등에서 차량 파손 및 인사 사고의 원인이 된다. 이러한 위험을 피하기 위해 후방의 장애물을 감지하는 후방 센서나 후방 카메라 등과 같은 운전자의 시야를 개선하는 ECU들이 개발되어 사용되고 있다. 이러한 ECU들의 도움을 받더라도 차량의 전, 후, 좌, 우 사방의 상황을 동시에 볼 수 없기 때문에 사고를 피하기 위해 운전자들은 주의를 기울여 운전해야 한다. 본 논문에서는 운전자의 안전 운행을 돕기 위해 차량 주변 영상을 실시간으로 제공하는 4SM 시스템을 설계하고 구현한다. 본 논문에서 제안하는 4SM 시스템은 차량의 전, 후, 좌, 우에 장착된 4대의 카메라로부터 입력된 영상을 통합하여 Bird's Eye View 영상을 운전자가 한 눈에 차량 주변 상황을 인식할 수 있도록 한다.

Recently, development of technologies for autonomous vehicles has been actively carried out. This paper proposes a computer vision system to recognize lanes, crosswalks, and stop lines for autonomous vehicles. This vision system first recognizes lanes required for autonomous driving using the RANSAC algorithm and the Kalman filter, and changes the viewpoint from the perspective-angle view of the street to the top-view using the fact that the lanes are parallel. Then in the reconstructed top-view image this system recognizes a crosswalk based on its geometrical characteristics and searches for a stop line within a region of interest in front of the recognized crosswalk. Experimental results show excellent performance of the proposed vision system in recognizing lanes, crosswalks, and stop lines.

Dunhuang murals are one of the most outstanding achievements in the art of traditional grotto painting in China, and are known as a "Wall Museum". As a representative of the heyday of Dunhuang murals, an in-depth exploration of Dunhuang murals from the perspective of color will help researchers understand the laws and connotations of color in Dunhuang murals during the Tang Dynasty and fully grasp the art of Dunhuang murals. The color system of the traditional Chinese "Five colors" concept expresses the cultural attributes and emotions of the Chinese people and has distinctive national characteristics. This thesis provides a theoretical grasp of the traditional Chinese "Five colors" view of color system, the Dunhuang murals of the Tang Dynasty, and the color configuration of the color composition principles, and uses the modern design principles of color composition to conduct an in-depth analysis of the configuration of the Dunhuang murals' use of color. Explore the unique characteristics of Tang Dynasty Dunhuang murals, and help modern designers master richer color application techniques by learning from and studying the harmonious patterns of Dunhuang murals to provide a new path for the dissemination of excellent Chinese traditional culture.

We present an efficient and robust algorithm to parametrize a perspective silhouette curve of a canal surface. We also detect each connected component of the silhouette. A canal surface is an envelope surface of a moving sphere with varying radii, which is defined by the center trajectory C(t) and radius function r(t) of the moving sphere. A canal surface can be decomposed to a set of characteristic circles. We derive the equations for the silhouette points on each characteristic circle, then parameterize the silhouette curve by using the equation. The sphere $S(t_*)$ with center point $C(t_*)$ and radius $r(t_*)$ intersects with the canal surface at a characteristic circle $K(t_*)$. The perspective silhouette of the sphere $S(t_*)$ from given view point consists of a circle $Q(t_*)$. By finding the values of t at which K(t) and Q(t) tangentially intersect, we detect each connected component of the silhouette curve.

This descriptive survey design study was aimed to investigate nursing students' perspectives of nursing care. One hundred seventeen junior or senior students in BSN program and 131 junior or senior students in RN-BSN program at K University were compared and contrasted in terms of their perspectives on nursing care. Using the instrument developed by Cho Kyoul-Ja and Song Mi-Ryung(1997), the data were collected from April 1st to April 30th in 2003. The findings of the research are as follows. 1. The average perspective score of the RN-BSN students was higher than that of the BSN students. 2. The RN-BSN students reported higher scores than those of the BSN students in perspectives on personal qualification and meanings, and perspectives on scope and function of their nursing care. However, there was no significant difference between the groups in overall nature and domains of nursing care. 3. In terms of the participants' demographic backgrounds such as, grades in the program, religion, history of hospitalization, there was no significant difference between the BSN and RN-BSN groups. 4. No significant difference was found within the RN-BSN group in terms of their nursing perspectives associated with the years of clinical experience. In conclusion, the score of nursing perspectives in RN-BSN student group was higher than that of the BSN students. No other differences were found in this study. The higher nursing perspective score in RN-BSN group is attributed to their clinical experience. Thus, it is suggested that philosophy and value of nursing should be taught early in nursing program in order for nursing students to obtain proper points of views on nursing care. In addition, nursing philosophy, holistic view, and humanistic values should be stressed in continuing education for clinical nurses in order for them to maintain dignitary perspectives in nursing care.

The study provided a perspective on which readers can see Newton's proof heuristically in order to overcome the difficulty of proof showing 'QT²/QR converges to the latus rectum of ellipse' in the proof of the inverse square law of Newton's Principia. The heuristic perspective is as follows: The starting point of the proof is the belief that if we transform the denominators and numerators of QT²/QR into expression with respect to segments related to diameter and conjugate diameter, we may obtain some constant, the desired value, by their relationship PV × VG/QV² = PC²/CD² in Apollonius' Conic sections. The heuristic perspective proposed in this study is meaningful because it can help readers understand Newton's proof more easily by presenting the direction of transformation of QT²/QR.
