바야흐로 21 세기를 열었던 유비쿼터스 기술은 그 결과물로써 스마트 기기를 낳았다. 그리고 본격적으로 스마트 시대를 열었다. 이에 단순히 탈것에서 진화하기 시작한 자동차는 IT기술과의 접목을 자연스레 하게 되었으며 이어서 스마트 자동차로의 진화적 완성을 시도하고 있다. 이러한 스마트 자동차는 기본적으로 차량 통신 네트워크 기술은 차량내 네트워크(IVN), 차량간 통신 네트워크(V2V communication network), 그리고 차량과 인프라간 통신 네트워크(V2I communication network)로 구성이 된다. 본 고에서는 차량 통신 네트워크 기술의 개념과 서비스, 시장 전망, 그리고 최근 기술개발과 표준화 동향을 알아본다.

The access to web applications has continuously evolved toward the adoption of content centric interfaces. Services and information items are much of user's concern than web sites. For an efficient accommodation of increasing needs of content oriented operations, the scope of domain names is extended in two directions. A naming scheme is derived that is suitable for resource level access units and the semantics of domain names is conceived as very flexible functions. First extension regards the removal of unnecessary TLD's of domain names for resource level binding. Second extension makes the resource level domain names rich in functional binding and consequently various applications can be directly triggered by the invocation of domain names without intervening medium. These extensions may lay a certain direction for the future internet evolution.

This study aims to analyze the key logic of the current C-P-N-D ICT ecological system, to find out the shortcomings of the current system, and then to offer policy suggestions for the establishment of a new creative contents industry ecological system; that is, ICCT (Information, Communication, Contents and Technology) System.

The purpose of the study was to analyze the concept of happiness that would be experienced in life of Korean cancer survivors. The concepts of happiness were analyzed using the Rogers' evolutionary concept analysis method for 11 papers satisfying the selection criteria, among domestic journals published from January 2000 to September 2017. The result of this study was that attributes of happiness were subjective experience, positive mind, meaning of life and formation of relationship. Antecedents were to accept-risk-of-life, cope-with-the-reality, implement-self-reflection and environmental-support. As a result of the concept, cancer survivors' inner strength increased, they became feeling love and pursuing new lives, and felt happiness through self-realization. This study is valuable to suggest a basic framework for the stepwise assessment that can improve the happiness of Korean cancer survivors and cancer survivors should be managed through multidisciplinary convergence programs.

Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

Development of 5th generation mobile telecommunication technology is visualizing ideal hyper-connected social information and communication technology (ICT). In particular, virtual reality (VR) technology is at the starting point for new expansion and leaps. This work defines virtual reality as media in this context and collects and analyzes discourse on its scalability around space and communication theory. We first elaborated the concept, starting with the early discussions of the virtual reality concept in 1990, and discussed the relationship between the physical world and digital information, expression and interaction immersion as a medium, simulation, art creation theory, and finally evolutionary development. In conclusion, beyond the discourse on the technology of virtual reality, academic subjects were required to have theoretical frameworks on cognitive science, neuroscience, social science, and humanities issues (ethics, personality, etc.) for the development and evolution of virtual reality. In other words, it is time for the evolution of virtual reality to be discussed, which can be moved beyond.

The purpose of this study was to investigate pre-service biology teachers' perception of the evolution. This study was to compare the views of pre-service biology teachers with no religion with those of christian preservice teachers. Subjects were 77 pre-service biology teachers who enrolled in an university and graduate school of education located in Seoul. The instrument of this study was a questionnaire which consisted of 14 items on 2 domains: the nature of science, the origins of human beings. The key results are as follows. Most pre-service teachers showed highly understanding of the characteristics of science. However pre-service biology teachers still possessed naive views on the distinction of law and theory. In terms of the methods of science, many of the pre-service biology teachers considered scientific theories to progress through the accumulation of observation and experiments or through changes and modifications in existing theories. Compared with the pre-service teachers with no religion, christian pre-service teachers had conflicting views and misconceptions about the origins of human beings. The factors of religion were found to be one of the important barriers which prevent them from understanding the origins of human beings. The results suggested that the education program for pre-service biology teachers integrating the concepts and development process of the scientific knowledges should be effective for understanding the nature of science. For pre-service biology teachers, It is important to understand conflicting views of the christian pre-service teachers who understand creationism as a science.

초기 우주의 구상성단과 같은 소규모 은하 빌딩블럭이 은하의 형성에 미치는 영향을 이해하기 위하여 우리는 완전히 새로운 개념의 화학적 진화모형을 구축하였다. 최근의 이론적 진보를 바탕으로 우리의 모델에서는 이전 모델과 달리 초신성의 폭발과 분출물이 원시 구상성단 내 잔존 가스에 아무런 영향을 끼치지 못하고 대부분 빠져나간다. 이 경우 화학적 진화는 질량이 큰 별의 윈드와 점근거성계열성의 분출물에 의해 좌우된다. 놀랍게도 우리의 모델은 오랜 난제인 구상성단 내 Na-Oxygen anticorrelation 및 다중항성종족의 기원을 자연스럽게 설명하면서 동시에 Lee, Joo, & Chung (2015) 이 최근 주장한 것처럼 은하벌지에 헬륨 함량이 매우 높은 항성이 존재할 것으로 예측한다. 이 결과는 은하의 헤일로와 벌지 형성에 매우 중요한 단서를 제공한다.
