Ability to make informed decisions by critically evaluating media information on socioscientific issues (SSI) is one of the crucial elements of scientific literacy that citizens should obtain. This study aims to investigate how middle school students evaluated media information about socioscientific issues (SSI) when they faced two different types of information (i.e., numerical and empathic information). To achieve the aim, 96 middle school students responded to the questionnaires asking them to evaluate reliability and persuasiveness of SSI media information. The questionnaires consisted of two sets of newspaper articles on each SSI (pro-numerical/empathic, against-numerical/empathic). After reading the articles, the students evaluated reliability and persuasiveness of each article and wrote the reasons for their evaluation. The results were as follows: First, the students believed that news articles with numerical information were more reliable than the ones with empathic information in all SSI contexts. They tended to trust scientific evidence and data from numerical information, and real cases, societal problems, expressions, and values from empathic information. In addition, they evaluated their reliability based on the logic of information, accuracy of information, breadth and depth of data, and quantity and quality of sources both numerical and empathic information. Second, in case of evaluating persuasiveness of the articles, they focused more on the values that information contained, richness and logicality of the information, rather than the types of information, regardless of the type of information.

The purpose of this study was to understand purchasing behavior on sauce products and the credibility of advertisement in Busan. For the study, 240 of samples taking cooking courses at welfare centers and private institutes were selected. The questionnaire consisted of demographic characteristics, the practical situation of purchasing sauce products, and the credibility of mess media advertisements. 260 questionnaires were distributed, among which 240 were returned and 233 were used for statistical analysis. The result of the study was as followed. Considering the practical situation of purchasing, the samples took information about sauce products from discount markets, and TV advertisements. Purchasing sauce products was done by themselves, and the main reason that they didn't purchase was health. Seeing the credibility of mess media advertisements, they trusted "The recommendation of a familiar person" most, department stores were the second highest, and TV advertisement was the third. The statistical differences partly existed depending on demographic characteristics: job, and material status. Identifying the decision making factors on sauce products was needed as further study.

This research analysis politic knowledge, politic awareness and politic socialization medium which influenced forming politic awareness for high school students. This purpose is that we find politic awareness of teenagers and how we teach politic education for teenagers effectively. After analysis, we found that awareness formed through home, school, colleague group and mess media influence teenagers to make their important factor of forming politic and administration and awareness level of politic and administration.

In this study of the domestic high school and middle school students to use the online education-website to measure the quality of service between SERVPERF model and the KS-SQI model fits which were analyzed further. Analysis using AMOS 7, SERVPERF for measuring quality of service reliability, responsiveness, assurance, empathy and tangibility, was a measurement model. KS-SQI for primary needs fulfillment, unexpected benefit were performance dimensions, reliability, individual empathy, positive assistance, accessibility and media tangibility, consist of process dimension was measured. In comparison of two models, the KS-SQI model on a path analysis showed better in terms of model fit indexes.

This study proposes new protocol protecting patients' personal record more safely as well as solving medical dispute smoothly by storing the record not into a computer server in hospitals but into the National Health Insurance Corporation computer server. The new protocol for electronic medical record is designed using RSA public key algorithm and DSA digital signature. In addition, electronic medical record systems are built up with more safety and reliability through certificate authority. The proposed medical information systems can strengthen trust between doctors and patients. If medical malpractice occurs, the systems can also provide evidence. Furthermore, the systems can be helpful to reduce medical accidents. The systems could be also utilized efficiently in various applied areas.

전 세계적으로 급증하고 있는 에너지 수요로 인해 오일, 가스 등의 에너지 생산 매체를 운송 할 수 있는 수송 수단인 배관에 대한 수요도 증가하고 있는 추세이다. 그러나 이러한 배관을 장시간 사용할 경우 노후화로 인해 발생되는 파공은 배관에 흐르는 유체 누설의 원인이 되고, 나아가서 경제 및 재난 피해를 야기할 수 있다. 따라서 다양한 배관 누설 검출 기술들이 개발되고 있는 추세이며, 이를 위해서는 신뢰성 있는 결함 모사 데이터의 확보가 매우 중요하다. 본 논문에서는 신뢰성 있는 데이터 수집을 위해 배관의 누설 상황을 모사 할 수 있는 테스트베드를 제어하고, 테스트베드에서 데이터를 안정적으로 취득할 수 있는 테스트베드 제어 및 데이터 취득 시스템을 제안한다.

This study was conducted to examine the level of exposure, credibility and usefulness of the food tourism information channel perceived by foreign tourists visiting Korea. A total of 230 survey questionnaires were distributed to Japanese and Chinese tourists, who account for the highest percentage of tourists visiting Korea. The results showed that tourists were segmented into three groups based on their participation in food tourism activities: culinary tourists, experiential tourists and general tourists. Japanese tourists participated more actively in food tourism activities than Chinese tourists. The information channel used most frequently by tourists was 'word-of-mouth,' while the least used channel was 'e-mail catalog contains food tourism information.' Culinary tourist most actively used online and offline channels to search for food tourism information. Perceived credibility and usefulness of the food tourism information channel differed by nationality and food tourist segments. This study provides meaningful implications regarding food tourism promotion strategies.

Flash memory software running on cellular phones and PDAs need to be tested extensively to cope with abrupt power and media faults. For those tests, we designed and implemented a Flash memory emulator with fault injection features. The fault injection tester has provided a helpful framework for designing fault recovery schemes and also for analyzing fault damages to the FTL (Flash Translation Layer) and file system for a Flash memory based system. In this paper, we discuss Plash memory fault types and fault injection features implemented on this Flash memory emulator. We then discuss in detail a design flaw revealed during fault injection tests. Specifically, it was revealed that a scheme that was believed to improve reliability instead, turned out to be harmful. In addition, we discuss post-fault behaviors of the FTL and the file system.

With the development of IoT and AI technologies and media, various digital devices are being used, and unmanned and automation is progressing rapidly. In particular, high-level image processing technology is required in fields such as smart factories, autonomous driving technology, and intelligent CCTV. However, noise present in the image affects processes such as edge detection and object recognition, and causes deterioration of system accuracy and reliability. In this paper, we propose a filtering algorithm using fuzzy weights to reconstruct images damaged by complex noise. The proposed algorithm obtains a reference value using noise judgment and calculates the final output by applying a fuzzy weight. Simulation was conducted to verify the performance of the proposed algorithm, and the result image was compared with the existing filter algorithm and evaluated.
