The present study examined the factors influencing individuals' risk information seeking and processing using the case of 2015 MERS outbreak in Korea. Analyses of two-wave online panel data demonstrated that perceived risk, negative affect, subjective norm, and information insufficiency predicted the risk information seeking/avoiding as well as information processing mode, which validates the Risk Information Seeking and Processing(RISP) model. More importantly, this study found new evidence that information seeking and systematic processing promoted MERS preventive behaviors. In addition, active SNS use moderated the link between perceived risk and negative affects about MERS crisis as well as the relationship between social normative pressure and to seek the risk related information.

Earthquake disaster frequently happens in Shizuoka Prefecture and it is commonly predicted that a giant earthquake(Tokai Earthquake) could occur in the near future. When a giant earthquake happens, extensive damage of lifelines will be expected. It is considered that the collection of damage information and the establishment of a communication network system are very important in order to restore lifelines quickly. And geographic information system(GIS) might playa very important role to grasp the spatial information of lifeline damage in a natural disaster. The authors' group had a research project to study a lifeline restoration support system with image processing and ad hoc networking in a natural disaster. The objectives of this presentation are to introduce our project and to show some results of our study. The authors finally constructed the GIS for the integration of damage information acquired by image processing and ad hoc networking.

자연어 정보처리 분야의 거듭된 발전은 다양한 언어처리 도구들의 출현을 가져왔다. 그러나 객관적인 성능 평가 기준의 부재로 인해, 개발된 도구들은 임의의 기준에 따라 평가될 수 밖에 없었다. 그 결과 성능 평가 결과는 평가자와 평가자가 제안한 기준에 따라 다를 수 밖에 없었고 따라서 평가 결과 자체 역시 설득력을 갖을 수가 없었다. 이와 같은 문제에 대한 해결책을 찾고자 하는 노력의 일환으로, 본 연구에서는 한국어처리 도구들 중 특히 구문분석기의 체계적이고도 객관적인 성능 평가를 목적으로 제작된 문장들과 관련 주석 정보들로 구성된 SERI Test Suites '97을 소개한다.

The advancement of information technologies including the Internet has affected the way of social information processing as well as brought about the paradigm shift to the information society. Accordingly, it is very important to study the process of social information processing over the digital media through which social information is generated, distributed, and led to social consensus. In this study, we analyze the mechanism of social information processing, identify a process model of social consensus and institutionalization of the results, and finally propose a set of information processing characteristics on the internet media. We deploy the ethnographic approach to analyze the meaning of group behavior in the context of society to analyze two major events which happened in Korean society. The formation process of social consensus is found to consist of 5 steps: suggestion of social issues, selective reflection on public opinion, acceptance of the issues and diffusion, social consensus, and institutionalization and feedback. The key characteristics of information processing in the Internet is grouped into proactive response to an event, the changes in the role of opinion leader, the flexibility of proposal and analysis, greater scalability, relevance to consensus making, institutionalization and interaction. This study contributes to the literature by proposing a process model of social information processing which can be used as the basis for analyzing the social consensus making process from the social network perspective. In addition, this study suggests a new perspective where the utility of the Internet media can be understood from the social information processing so that other disciplines including politics, communications, and management can improve the decision making performance in utilizing the Internet media.

This paper presents a multimodal emergency recognition system based on visual information, audio information and gravity sensor information. It consists of video processing module, audio processing module, gravity sensor processing module and multimodal integration module. The video processing module and gravity sensor processing module respectively detects actions such as moving, stopping and fainting and transfer them to the multimodal integration module. The multimodal integration module detects emergency by fusing the transferred information and verifies it by asking a question and recognizing the answer via audio channel. The experiment results show that the recognition rate of video processing module only is 91.5% and that of gravity sensor processing module only is 94%, but when both information are combined the recognition result becomes 100%.

The purpose of this study was to find out the degree of science problem solving by the information processing types and cognitive styles of 235 6th grade students. The results of this study were as follows. First, as the students got higher scores in the two types of information processing, they could solve more science achievement items and creative problem solving items correctly. And as the students got higher scores in simultaneous information processing test, they could solve more scientific concept understanding items. Secondly, as the students were more field-independent, they could solve more science achievement items and creative problem solving items. And especially in solving scientific concept understanding items, much higher field-independence was required. Finally, there was a significant difference on the distributions of cognitive styles by the information processing types. As the students got higher scores in the two types of information processing, their cognitive style tended to be more field-independent.

This research attempts to suggest a detecting method for cutting position of an object using the neural network, which is one of intellectual methods, and the digital image processing method. The extraction method of object information using the image data obtained from the CCD camera as a replacement of traditional analog sensor thanks to the development of digital image processing. Accordingly, this research determines the threshold value in binary-coding of an input image with the help of image processing method and the neural network for the real-time gray-leveled input image in substitution for lighting; as a result, a specific position is detected from the processed binary-coded image and an actual system designed is suggested as an example.

Information-Centric Vehicular Ad Hoc Network (IC-VANET) is a promising network architecture for the future intelligent transport system. Video streaming applications over IC-VANET not only enrich infotainment services, but also provide the drivers and pedestrians real-time visual information to make proper decisions. However, due to the characteristics of wireless link and frequent change of the network topology, the packet loss seriously affects the quality of video streaming applications. In this paper, we propose a REceiver-Driven loss reCOvery Mechanism (REDCOM) to enhance video dissemination over IC-VANET. A Markov chain based estimation model is introduced to capture the real-time network condition. Based on the estimation result, the proposed REDCOM recovers the lost packets by requesting additional forward error correction packets. The REDCOM follows the receiver-driven model of IC-VANET and does not require the infrastructure support to efficiently overcome packet losses. Experimental results demonstrate that the proposed REDCOM improves video quality under various network conditions.
