  • Objectives: This paper aims to explain principles of gist-based health message design and discuss their implications for health promotion and public health education. Methods: After reviewing Reyna and Brainerd's Fuzzy Trace Theory(FTT), the authors explicate how to transform FTT into a practical guidance of health message design. Our explication is based upon FTT's reasoning that human intuition, rather than analysis, takes a primary role in message recall and comprehension, followed by judgment and decision making. We expect gist-based message design to be appropriate to serve such intuition. Results: Four principles of gist-based message design are offered: (1) provision of qualitative, as well as quantitative, information of gist, (2) inclusion of visual images corresponding to gist, (3) use of effective message formats to emphasize the gist (4) inclusion of relevant reasons and contextutal information. Conclusions: Gist-based message design has theoretical and practical implications for health promotion, specifically in the field of public health education, the press and governmental communication toward the public, and provider-patient communication in medical settings.

  • 건강 관련 정보들이 범람하는 인터넷에서 핵심정보를 효과적으로 전달하는 것은 매우 중요하다. 본 연구는 웹진 건강자료에 나타난 건강 메시지의 특성을 분석하고 핵심정보를 효과적으로 전달하기 위한 디자인방법을 모색하고자 하였다. 이를 위해 식품의약품안정처에서 제공하는 총 72개 건강자료의 내용을 텍스트와 시각자료로 구분하여 '건강 메시지의 내용', '핵심정보의 빈도와 위치', '직관적 표현'을 중심으로 분석하였고, 특성에 따라 건강자료의 유형을 구분하기 위해 군집분석을 실시하였다. 그 결과 건강 관련 텍스트는 주로 사실과 방법에 관한 내용으로 구성되어 있고, 시각자료는 주로 개념에 집중되어 있는 것으로 나타났다. 그리고 텍스트와 시각자료 모두 핵심정보를 효과적으로 제시하는데 미흡한 점이 발견되었으며, 전문용어와 수량정보에 대한 직관성을 높이기 위한 방법을 모색하는 것이 필요한 것으로 나타났다. 연구결과에 기반하여 인터넷에서 효과적으로 핵심정보 중심의 건강자료를 디자인하기 위해서 고려해야 할 점을 제안하였다.

  • 이 연구에서는 일반인이 건강증진 메시지 디자인과 관련하여 핵심정보 제시, 내용의 유용성, 형식, 직관성의 중요성을 어떻게 인식하는지와 현재 식품의약품안전처에서 발간하는 웹진의 텍스트와 시각자료가 위 네 가지 측면에서 얼마나 효과적으로 디자인되었다고 인식하는지를 조사하였다. 그리고 이러한 인식에 영향을 미치는 개인특성 변인이 무엇인지를 탐색적으로 연구하였다. 이를 위해 294명의 성인들을 대상으로 설문조사를 실시하였으며, 중요도 및 실행도 분석(Importance-Performance Analysis)을 실시하였다. 그 결과 연구참여자들은 텍스트 디자인에서 내용의 유용성을, 시각자료 디자인에서 핵심정보 제시를 가장 중요한 항목으로 인식하였으며, 텍스트와 시각자료 모두 형식 측면에서의 실행도가 가장 높게 나타났다. 시각자료의 핵심정보 제시와 직관성은 가장 중점적으로 개선해야 할 원리인 것으로 나타났다. 그리고 개인의 건강관심도가 건강증진 메시지 디자인 원리의 중요도와 실행도 인식에 가장 큰 영향을 미치는 것으로 나타났다. 이러한 연구결과에 기반하여 효과적인 건강증진 메시지 개발을 위한 원리와 전략에 대해 논의하였다.

  • A variety of systems have been attempted for effective urban management. In this paper, we introduce integrated urban management system (IUMS), which mainly consists of optical line terminal (OLT), optical network terminal (ONTs) and wireless access points (APs), by combining passive optical network (PON) and radio over fiber (RoF) technologies so as to take advantages of both two systems. Further, several IUMS services including disaster detection and prevention system (DDPS), bus information system (BIS) and real time location system (RTLS) are demonstrated in order to employ IUMS for the realization of future ubiquitous city (U-city).

  • In JPEG2000, the Cohen-Daubechies-Feauveau (CDF) 9/7-tap wavelet filter adopted in lossy compression is implemented by the lifting scheme or by the convolution scheme while the LeGall 5/3-tap wavelet filter adopted in lossless compression is implemented just by the lifting scheme. However, these filters are not optimal in terms of Peak Signal-to-Noise Ratio (PSNR) values, and irrational coefficients of wavelet filters are complicated. In this paper, we proposed a method to optimize image quality based on wavelet filter design and on wavelet decomposition. First, we propose a design of wavelet filters by selecting the most appropriate rational coefficients of wavelet filters. These filters are shown to have better performance than previous wavelet ones. Then, we choose the most appropriate wavelet decomposition to get the optimal PSNR values of images.

  • Recently, various AR-based product design methodologies have been introduced. In this paper, we propose technologies for enhancing robust augmentation and immersive realization of virtual objects. A robust augmentation technology is developed for various lighting conditions and a partial solution is proposed for the hand occlusion problem that occurs when the virtual objects overlay the user' hands. It provides more immersive or natural images to the users. Finally, vibratory haptic cues by page motors as well as button clicking force feedback by modulating pneumatic pressures are proposed while interacting with virtual widgets. Also our system reduces gabs between modeling spaces and user spaces. An immersive game-phone model is selected to demonstrate that the users can control the direction of the car in the racing game by tilting a tangible object with the proposed augmented haptic and robust non-occluded visual feedback. The proposed methodologies will be contributed to the immersive realization of the conventional AR system.

  • The cleaning efficiency of reverse osmosis (RO) membranes inevitably fouled by organic foulants depends upon both chemical (type of cleaning agent, concentration of cleaning solution) and physical (cleaning time, flowrate, temperature) parameters. In attempting to determine the optimal procedures for chemical cleaning organic-fouled RO membranes, the design of experiments concept was employed to evaluate key factors and to predict the flux recovery rate (FRR) after chemical cleaning. From experimental results and based on the predicted FRR of cleaning obtained using the Central Composite Design of Minitab 17, a modified regression model equation was established to explain the chemical cleaning efficiency; the resultant regression coefficient ($R^2$) and adjusted $R^2$ were 83.95% and 76.82%, respectively. Then, using the optimized conditions of chemical cleaning derived from the response optimizer tool (cleaning with 0.68 wt% disodium ethylenediaminetetraacetic acid for 20 min at $20^{\circ}C$ with a flowrate of 409 mL/min), a flux recovery of 86.6% was expected. Overall, the results obtained by these experiments confirmed that the equation was adequate for predicting the chemical cleaning efficiency with regards to organic membrane fouling.
