해설판은 자기안내식 해설에서 흔히 이용되는 정보전달 매체로서 해설효과의 극대화를 위해서는 해설판과 이를 이용하는 탐방객에 대한 이해가 필요하다. 본 연구는 중요도-성취도 분석(Importance-Performance Analysis: IPA)을 이용하여 탐방객의 인구사회학적 특성과 방문행태에 따른 자기안내식 해설판의 주요 디자인 속성에 대한 현 관리상태의 평가를 통하여 보다 효과적인 해설판 관리를 위한 기초자료를 얻기 위해 시행되었다. 자료수집은 2003년 8-9월중 내장산 국립공원 내 자연관찰로 탐방객을 대상으로 한 설문조사를 통하여 이루어 졌으며, 총 276명의 응답이 본 연구의 분석에 이용되었다. 선정된 30개 속성에 대한 IPA 결과, 여성(23.3%)이 남성(13.3%)보다, 저연령층(43.3%)이 고연령층(0.0%)보다, 고학력 그룹(36.7%)이 저학력 그룹(0.0%)보다, 중그룹(33.3%)이 대그룹(10.0%)이나 소그룹(16.7%)보다, 아동동반 그룹(66.7%)이 아동부동반 그룹(20.0%)보다 더 많은 해설판 디자인 속성에 대하여 높은 중요도와 낮은 성취도를 보여 높은 '우선시정 필요(Concentrate Here: CH)' 항목율을 나타내는 것으로 조사되었다. 특히 아동동반 그룹은 가장 높은 '우선시정 필요(CH)' 항목율을 나타냈다. 본 연구의 결과는 다양한 탐방객을 고려한 해설판 다자인의 필요성을 시사하고 있다. 또한, 표준화된 해설판 디자인 항목의 개발을 통해서 자연관찰로의 해설판에 대한 IPA 및 여타 평가수행의 신뢰성과 효율성을 기대할수 있을 것이다.

Electrocardiogram (ECG) and blood pressure (BP) are main vital signs which are the standards in most medical settings in assessing the most basic body functions. Multi parameters are desired in providing more information for health professionals in order to detect or monitor medical problems of patients more precisely. This study urges us to develop a robust wireless healthcare monitoring system which has multiple physiological signs measurements on real time that applicable to various environments which integrates wireless sensor network technology and code division multiple access (CDMA) network with extended feature of locally standalone diagnosis algorithms that implemented in tell phone. ECG signal and BP parameter of the patients are routinely be monitored, processed and analyzed in details at cell phone locally to produce useful medical information to ease patients for tracking and future reference purposes. Any suspected or unknown patterns of signals will be immediately forwarded to hospital server using cell phone for doctors' evaluation. This feature enables the patients always recognize the importance of self-health checking so that the preventive actions can be taken earlier through this analytic information provided by this monitoring system because "Prevention is better than Cure".

This paper presents a computer program for easy and rapid disease diagnosis of olive flounder diseases. To design the program, standard diagnosis process of the 14 olive flounder diseases was first setup, then implemented four-steps diagnosis program. To run program, first input fundamental information such as water temperature, size of the diseased fish. Then sequentially, three categories of key factors for disease diagnosis which include external clinical signs, internal clinical signs and microscopic observations are selected. When a user selects the observed signs of olive flounder from the listed options, the program provides maximum 5 presumed disease candidates in order. The disease information, treatment and prevention methods are provided by connected web server through internet. The program would support fish doctors and farmers by providing easy and rapid diagnosis of diseased olive flounder.

This paper presents the development of a 3D printed humanoid robotic hands of SignBot, which can perform Malaysian Sign Language (MSL). The study is considered as the first attempt to ease the means of communication between the general community and the hearing-impaired individuals in Malaysia. The signed motions performed by the developed robot in this work can be done by two hands. The designed system, unlike previously conducted work, includes a speech recognition system that can feasibly integrate with the controlling platform of the robot. Furthermore, the design of the system takes into account the grammar of the MSL which differs from that of Malay spoken language. This reduces the redundancy and makes the design more efficient and effective. The robot hands are built with detailed finger joints. Micro servo motors, controlled by Arduino Mega, are also loaded to actuate the relevant joints of selected alphabetical and numerical signs as well as phrases for emergency contexts from MSL. A database for the selected signs is developed wherein the sequential movements of the servo motor arrays are stored. The results showed that the system performed well as the selected signs can be understood by hearing-impaired individuals.

본 연구는 인적재난 분야에 다양한 재난전조자료를 수집 분석하여 재난 위험등급을 결정하는 의사결정체계를 구축할 목적으로 재난전조 정의, 재난전조정보를 분석하기 위한 분류체계, 재난전조정보 위험등급을 판단하기 위한 논리적 알고리즘, 대응 조치사항을 포함한 권고사항 등을 연구하였다. 본 연구에서 의사결정체계를 위해 적용된 온톨로지 기법은 기본요소들의 분류 및 3계층 속성 분류만을 도입하였고, 텍스트 마이닝 기법에서는 용어의 빈도수 분석 및 신뢰도 계산 부분을 도입하여 연관성 규칙의 기본구조를 밝혀냈다. 이 기본구조에 과거 재난사례를 적용하여 연관성 규칙을 생성하였으며, 새로운 재난전조정보와 비교하여 위험등급을 추론하는 사례기반추론 기법을 사용하였다. 본 연구에서 제시된 지능형 의사결정체계는 의사결정자가 재난전조정보를 바탕으로 위험등급을 결정하여 사전예방조치를 할 수 있도록 도와주며, 궁극적으로 재난발생 가능성을 줄일 수 있다.

This paper describes a robust mobile u-healthcare system with multiple physiological signs measurement capability in real time with integration of WSN(wireless sensor network) technology and CDMA(code division multiple access) network. A cellular phone receives health data in WSN and performs local physiological signs analysis at a phone processor, and then transmits abnormal data to server for further detail or precise health signal evaluation by a medical doctor over a CDMA network. Physiological signs of the patients are continuously monitored, processed and analyzed locally at cellular phone process to produce useful medical information for diagnosis and tracking purposes. By local simple analysis in cellular phone processor we can save the data transmission cost in CDMA network. By using the developed integrate ubiquitous healthcare service architecture, patients can realize self-health checking so that the prevention actions can be taken earlier. Appropriate self-monitoring and self-management can cure disease and relieve pain especially for patients who suffer from chronic diseases that need long term observation.

The purpose of this study is to propose a new direction for color schemes of city signages to provide psychological stability to business owners and improve business value. Types of city sign color schemes and Feng Shui awareness of business owners were examined. Color schemes for signs were proposed, reflecting city landscape colors, color perception theory, and the Feng Shui Sangsaeng Sanggeuk theory. Results of the study can be summarized as follows. First, in order to secure colorscape quality of existing city buildings, signs should be small and consist of only three or fewer colors. Second, existing signage colors and the Feng Shui ideas of business owners have something in common with the five traditional cardinal colors. Thus, it can be interpreted that Feng Shui ideas are deeply rooted in the color use awareness of the Korean people. Third, background colors of signages can reflect the idea of innate Sangsaeng according to the Bonmyeonggung of business owners. The concept of acquired Sanggeuk can also be applied to other design elements such as characters. Fourth, as a second choice according to the function of sign, city landscape or preference of business owner, etc., the background color can remain a color of Sangsaeng, while other design elements such as characters can use a color scheme corresponding to Bihwasaek. Fifth, signs can create a statement and stand out using lightness contrast or saturation contrast theories. A variety of sign color schemes are also possible just by altering the lightness and saturation levels.

In this paper, we present Emergency exit signs are installed to provide escape routes or ways in buildings like shopping malls, hospitals, industry, and government complex, etc. and various other places for safety purpose to aid people to escape easily during emergency situations. In case of an emergency situation like smoke, fire, bad lightings and crowded stamped condition at emergency situations, it's difficult for people to recognize the emergency exit signs and emergency doors to exit from the emergency building areas. This paper propose an automatic emergency exit sing recognition to find exit direction using a smart device. The proposed approach aims to develop an computer vision based smart phone application to detect emergency exit signs using the smart device camera and guide the direction to escape in the visible and audible output format. In this research, a CAMShift object tracking approach is used to detect the emergency exit sign and the direction information extracted using template matching method. The direction information of the exit sign is stored in a text format and then using text-to-speech the text synthesized to audible acoustic signal. The synthesized acoustic signal render on smart device speaker as an escape guide information to the user. This research result is analyzed and concluded from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinder system.
