고령친화적인 환경은 고령자의 자립생활을 위한 여건을 조성해 줄 뿐 아니라 장애인, 아동, 임산부 등은 물론 일반인에게까지도 편리한 생활환경을 제공해 주는 이점이 있다. 본 연구는 부산 거주 고령자가 인지하는 부산시 물리적 생활환경의 고령친화정도를 파악하고 고령자의 특성에 따라 고령친화도가 어떠한 차이를 보이는지를 규명하였다. 본 연구는 부산지역 16개 구에 거주하는 60세 이상 고령자 525명을 대상으로 일대일 면접방법을 이용하여 조사하였다. WHO의 고령친화도시 가이드라인 8개 영역 중 물리적 환경영역에 속하는 3개 영역인 야외공간과 건물, 교통, 주택영역과 관련된 34개 항목의 고령 친화도를 4점 척도를 이용하여 조사하였다. 조사결과 고령자는 3개 영역의 물리적 생활환경의 고령친화도가 중간 정도 수준이라고 인지하고 있어 개선이 필요한 것으로 나타났다. 또한 3개 영역 중 특히 주택영역에 대한 고령 친화도는 가장 낮은 것으로 나타나 고령자 주택의 개선을 위한 방안마련이 필요한 것으로 나타났다. 마지막으로 고령자가 인지하는 주변 생활환경의 고령 친화도에 영향을 미치는 고령자 특성은 경제수준, 주택유형, 주택소유상태, 건강상태인 것으로 나타나 고령친화적인 생활환경을 계획할 때 이들 특성에 대한 고려가 필요한 것으로 나타났다.

The purpose of study is to investigate the current user interface level of air traffic control system with the usability analysis and satisfaction survey questionnaire on user satisfaction. Think aloud protocol is used to identify not only task analysis, but also the level of user-friendliness of the FIMS and ASDE system, and the user interface questionnaires was conducted by QUIS. We collected data from 6 controllers for Think aloud protocol and 15 controllers for QUIS in Incheon airport. The results showed that the system was the valuable tool for ensuring human performance with the support of memory and the facilitation of decision-making tasks. It helps air traffic controllers perform better and minimize errors in a congested time. The human-computer interface system design, however, was not applied, which led to the increase of workload. Air traffic controller participation in software development provided excellent examples for applications in terms of software in FIMS. Based on these results, the study provided that the usability of system interface was necessary to take into account human factors. The development and design of system was discussed in User Interface environment.

In this research, we propose a remote speech input unit, a new method of user-friendly speech input in speech recognition system. We focused the user friendliness on hands-free and microphone independence in speech recognition applications. Our module adopts two algorithms, the automatic speech detection and speech enhancement based on the microphone array-based beamforming method. In the performance evaluation of speech detection, within-200msec accuracy with respect to the manually detected positions is about 97percent under the noise environments of 25dB of the SNR. The microphone array-based speech enhancement using the delay-and-sum beamforming algorithm shows about 6dB of maximum SNR gain over a single microphone and more than 12% of error reduction rate in speech recognition.

Future robots, especially service and personal robots, will need much more intelligence, robustness and user-friendliness. The ability to learn contributes to these characteristics and is, therefore, becoming more and more important. Three of the numerous varieties of learning are discussed together with results of real-world experiments with three autonomous robots: (1) the acquisition of map knowledge by a mobile robot, allowing it to navigate in a network of corridors, (2) the acquisition of motion control knowledge by a calibration-free manipulator, allowing it to gain task-related experience and improve its manipulation skills while it is working, and (3) the ability to learn how to perform service tasks ...

This study which aimed to propose development directions for the future housing through the social change tries to predict the change of the future. Establish directions for planning of concept-Sustainability. Human-friendliness. High Technology and, with reference to case study and literature judge feasibility of them. The major findings were as follows : 1. Development direction related to the future housing can be classified into 7 principle : energy-saving, resource-saving, natural adaptation, community, user participant, super high level, and home intelligent. 2. Planning factors of the future housing can be divided into several itemes.

본 연구의 목적은 유-투어 시스템의 합리적 행동이론(TRA)을 사용하여 관련 시사점을 제시하는 것이다. 여기서 크게 사용자 친숙성(인지적 요인), 인지된 유용성(정서적 요인)과 구매 의도(능동적 요인) 등 세 가지 구조로 연구 모형이 구성되었다. 본 연구는 총 153명의 응답자 표본을 갖고 분석하였는데, 적은 표본 수를 고려하여 PLS-SEM 방법을 적용하였다. 또한, 연구 모형 내 각 경로에서 비선형 관계를 탐색하기 위하여 WarpPLS 소프트웨어를 활용하였다. 분석 결과, 제안된 연구 모델은 통계적으로 유의하였고, 유투어 시스템이 제안된 TRA 이론의 적용 가능성을 보여 주었다. 또한, 추가 분석으로서, 연구 모형 내 각 경로에서 비선형 관계로서 J 형태의 가능성을 보여주면서, 종속요인에 부분적으로 부(-)의 영향이 있다는 사실을 보여 주었다. 그리고 구매의도의 기반이 되는 소득변수는 제안된 모형 내 각 경로에 조절적 효과를 줄 수 있음을 실증적으로 제시하였다.

The building construction sector has been blamed as the main culprit of environmental contamination worldwide. So, there shall be some constructive alternatives in architectural engineering. As one of the alternatives, the LEED ("Leadership in Energy and Environmental Design") has been introduced since 1990s and has been well recognized in saving the resources and energy. "LEED" has also been introduced in Korea since 2002 but it has not put priority on the eco-friendliness of indoor space. In this study, the international and domestic green systems were analyzed and compared in order to restructure the checklist for indoor space. Using the restructured checklists, the questionnaire were sent to 180 people using 6 office buildings which passed the domestic "LEED" certification. LEED certification system put priority on the air quality and heating/cooling environment in its evaluation section and items. However, according to the results of the study, it was found that the people using the buildings were not satisfied enough with the air environment of buildings along with their other indoor environment items. This shows that even though the office buildings are designed according to the requirements of LEED, the buildings do not meet the occupier's needs. In addition, it showed that the evaluation items should be improved so that they are useful to enhance the satisfaction of the occupiers' needs. The paper could be useful in establishing standard for eco friendliness of indoor space of office buildings which pass the LEED certification as the basic data for increasing energy efficiency and working efficiency of occupiers of the buildings.

Life-cycle assessment (LCA) is often employed to quantify the environmental impact of a product in a comprehensive manner. The aspects of performance and usability as well as that of eco-friendliness should be considered in an integrated manner for the market competitiveness of an eco-friendly product. The present study developed a product improvement plan for an eco-friendly electric heater by benchmarking two small-size electric heaters (companies 'H' and 'T') in terms of performance, usability, and eco-friendliness. The performance measurements such as temperature, humidity, wind speed, noise, and power consumption were collected while the two heaters were operated in a laboratory setting. Then, the usability evaluations such as aesthetics, operation satisfaction, performance satisfaction, and overall satisfaction were surveyed for the two heaters using a 5-point scale (1 for very unsatisfied and 5 for very satisfied). Lastly, the LCA analysis was conducted by following the six-step process of eco-friendly product design provided by KEITI. The analysis results of the two products being integrated with the aspects of product, service, and user, four design improvement directions such as eco-efficient, smart, modularized, and user-support were recommended for an eco-friendly electric heater. These proposed concepts would be useful to develop an eco-friendly electric heater design with a high level of market competitiveness.
