Performance evaluation has been done using financial indices which are generally regarded as inappropriate for the organizations which are innovative and progressive. Thus, the Balanced Scorecard(BSC) was developed considering long term performance and invisible performance. This BSC has four perspectives of finance, customer, internal operation, and learning. Based on the BSC, a new BSC has been derived with a fifth view of environmental and social perspective, which is now called as a Sustainability BSC. In this study, we evaluated Green IT initiatives using the Sustainability BSC. The initiatives are categorized as RFID, telepresence, paperless office, logistics management etc. The initiatives were evaluated from the view of five perspectives, resulting in high cor relationships among finance, internal operation, and environmental and social perspectives. Namely, good initiatives from the view of environmental/social perspective are also evaluated as good from the view of finance and internal operation perspectives. In this study, we recommend organizations to introduce Green IT initiatives by showing how Green IT initiatives have contributed to the organizations.

LIN(Local Interconnect Network) 통신은 CAN(Controller Area Network) 통신과 더불어 차량용 통신으로 많이 사용되고 있다. LIN 통신은 필요 성능의 수준이 높지 않은 장치 및 시스템이나 비용의 경제적인 측면에서 CAN 통신의 하부버스로 많이 사용되며 LIN 노드에 개수도 점차 늘어나고 있다. 그렇기 때문에 LIN통신으로 시스템 제어 및 모니터링 프로그램을 GUI(Graphic User Interface)로 제작한다면 시스템 상태의 디스플레이 및 모니터링이 수월해진다. 함수와 GUI로 제작되는 LabVIEW는 다른 텍스트 언어기반 개발 프로그램에 비해 설계 시간 단축 및 사후 관리도 쉽다는 장점이 있다. 본 논문에서는 LabVIEW로 제작한 IBS 모듈 기능 검사 장비개발을 통해 LIN 통신으로 송수신되는 데이터를 확인하고 모니터링, 그리고 설계가 용이하다는 것을 소개하고자 한다.

The environment which surrounds us such as climates, technology change rapidly. Forecasting the future of food by reviewing the subject at the moment would be meaningful, because we could understand the impact of new technology, set the new goal and create the future by speaking out on issues of our concern and by our choices. There are two points of view on our future, one is pessimistic view due to the food and the water shortage, as well as environmental contamination. Another is optimistic view mainly because of innovative technologies. Biotechnology would enable to develope the personalized food using nutrigenomics, nutrigenetics, and nutraceuticals. Nanotechnology and shelf-life extension techniques would contribute great deal to the development of the future food. Consumer's concern for the health and the wellness as well as palatability would affect the development of future food so that the involvment of food cookery scientists are more important to meet the consumer's needs and trends.

A remotely located synchronization system which is locked to the remote master clock has been implemented by using GPS Common-View technique. The measurement results showed that the accuracy of the remote synchronization system could be kept within a few parts in $10^{-12}$ and MTIE(Maximum Time Interval Error) met the ITU-T Recommendation(G.811). A prototype system having fully automatic operational functions has been realized up to now and is expected to be used in the network synchronization in the near future.

The purpose of the study was to establish a new view of textbook which may contribute to the abolishment of the instruction mainly based on the only textbook and to the promotion of creativities of students. We first reviewed science textbooks and related teaching-learning materials of foreign countries with emphasis on the relationship among textbook and teaching-learning materials and practical use of them. In western countries the roles of traditional textbook has been changed. That is, various kinds of materials such as reading book, work-book, worksheet, experimental guidebook, filmstrips are used to raise effect of instruction besides of traditional type of textbook. Secondary, we identified the problems related to the science textbook-view of textbook, textbook contents, practical use of textbook-through opinion survey administered to principals akd teachers of elementary schools. The results of the survey are as follows; Concerning the view of textbook, most teachers did not recognize textbook as an absolute materials. They thought that textbook contents could be taught reorganized according to their judgements. On the contrary, teachers responded to the question of whether or not they follow contents of textbook as they are presented in it were approximately 30%. Further, more than 75% of them have seldom used instructional materials except textbooks. In order to revise the problems of our present textbook as stated above, a new view of textbook should be established. We, above all, established 4 basic premises for searching a new view of textbook. 1) Textbook should not be considered as the only material but as being at the center of various teaching -learning materials. 2) The importance of textbook should be illustrated Among Curriculum, textbook and related teaching-learning materials, instruction and evaluation. 3. Textbook contents should not be regarded as definitely fixed or absolute ones. 4. Human being can understand environment more fully by commanding his swnsory organ multilaterally. Under these premises we disscussed about curriculum and textbook, textbook, and instruction, akd evaluation method.

Multi-view images, which are widely used for providing free-viewpoint services, can enhance the quality of synthetic views when the number of views increases. However, there needs an efficient representation method because of the tremendous amount of data. In this paper, we propose a method for generating point cloud data for the efficient representation of multi-view color and depth images. The proposed method conducts sequential reconstruction of point clouds at each viewpoint as a method of deleting duplicate data. A 3D point of a point cloud is projected to a frame to be reconstructed, and the color and depth of the 3D point is compared with the pixel where it is projected. When the 3D point and the pixel are similar enough, then the pixel is not used for generating a 3D point. In this way, we can reduce the number of reconstructed 3D points. Experimental results show that the propose method generates a point cloud which can generate multi-view images while minimizing the number of 3D points.

Since July of 2012, the 3D video extension of H.264/AVC has been under development to support the multi-view video plus depth format. In 3D video applications such as multi-view and free-view point applications, synthesized views are generated using coded texture video and coded depth video. Such synthesized views can be distorted by quantization noise and inaccuracy of 3D wrapping positions, thus it is important to improve their quality where possible. To achieve this, the relationship among the depth video, texture video, and synthesized view is investigated herein. Based on this investigation, an edge noise suppression filtering process to preserve the edges of the depth video and a method based on a total variation approach to maximum a posteriori probability estimates for reducing the quantization noise of the coded texture video. The experiment results show that the proposed methods improve the peak signal-to-noise ratio and visual quality of a synthesized view compared to a synthesized view without post processing methods.

인터넷이 활성화되면서 다양한 웹 기반 서비스가 제공되어진다. 그 가운데 하나가 VOD(Video On Demand) 서비스이다. VOD는 다양한 프로그램을 사용자가 원하는 시점에 볼 수 있도록 한다. VOD 서비스를 유료화할 경우 시청한 양만큼 요금을 지불하는 pay-per-view 방법을 생각할 수 있다. Pav-per-view방식으로 서비스를 하는 경우 사용자는 각 프로그램을 시청한 양에 따라 요금이 부과되고 서비스 제공자는 부과된 요금이 정당함을 보증하는 공정성을 제공하여야 한다. 또한 사용자의 시청 내역을 타인으로부터 보호하는 기밀성이 보장되어야 한다. 이 연구에서는 기밀성과 공정성을 제공하는 웹 기반 pay-per-view 방식을 개발하였다. 이 논문에서 제안된 pay-per-view 방식은 대칭키 암호 기법을 이용하여 내용 및 자료 요청에 대한 기밀성을 제공하며 전자 서명과 다중 해쉬를 사용하여 사용자의 요금 부과에 대한 공정성을 제공한다. 또한 제안된 방식은 반복적으로 시청되는 내용에 요금을 차등하게 부과할 수 있는 유연성을 가지고 있다.

WebView is a vital component in smartphone platforms like Android, Windows and iOS that enables smartphone applications (apps) to embed a simple yet powerful web browser inside them. WebView not only provides the same functionalities as web browser, it, more importantly, enables a rich interaction between apps and webpages loaded inside the WebView. However, the design and the features of WebView lays path to tamper the sandbox protection mechanism implemented by browsers. As a consequence, malicious attacks can be launched either against the apps or by the apps through the exploitation of WebView APIs. This paper presents a critical attack called Supplementary Event-Listener Injection (SEI) attack which adds auxiliary event listeners, for executing malicious activities, on the HTML elements in the webpage loaded by the WebView via JavaScript Injection. This paper also proposes an automated static analysis system for analyzing WebView embedded apps to classify the kind of vulnerability possessed by them and a solution for the mitigation of the attack.
