보행보조기를 사용하는 노약자나 환자들의 경우는 대부분이 다리의 힘이 부족하여 장시간 걸을 수 없기 때문에 보행 중간에 잠깐씩 쉬어야 하는 경우가 많다. 따라서 육체적으로 약화된 노인이나 환자들이 안전하게 보행을 실시할 수 있도록 보행 능력을 보조하면서도 생체측정 및 IT응용 제품을 사용할 수 있도록 추가적인 다기능 보행보조기의 개발이 절실히 요구되고 있다. 본 연구는 기존 보행보조기의 한계를 극복하기 위해 노인 중심의 새로운 가치가 부여된 보행보조기의 디자인에 관한 내용으로써, 허리가 굽은 고령의 노인을 위한 보행보조기 중심으로 진행되었다.

The Korean society is recently becoming the aging society at an unprecedentedly rapid speed. Following the increase of the older population, their needs for special care is also rocketing. However, due to the increase of working women, nuclear-families, and old persons living alone, new facilities for the elderly such as nursing home are urgently needed. Thus, many nursing homes for the elderly are also rapidly providing. It is needed to examine if such nursing homes are properly designed for the dependent elderly to live. This study was carried out by the field observation using a checking sheet with measuring and taking photograph. The subjects were 12 nursing homes which gave positive responses for walking through their facilities. The items for observing and measuring were made based on the regulation on improving the facilities for the disabled, the elderly, and the pregnant. Whether each item fits the regulation or not was examined. The 9 areas in each nursing home were examined : entrance, hallway and corridor, stair, elevator, ramp, bed room, shower and locker room, bathroom, and rest room. It was founded that many accessible-related items were met. However, many supportive-related items such as ones for the visual disabled, and many supportive-related and accessible-related ones for bathroom, shower room, and restroom were unmet. In the process of this research, it was founded that the tool for evaluating the design of nursing home in terms of universal design should be developed.

Objective: The current study aimed to investigate the accessibility and usability of the disabled person while using the everyday facility. Background: The national laws regulated accommodation of persons with disabilities, but our knowledge on the practical usefulness of the laws and acceptance by the users is still far from complete. Method: Compliance with laws was checked throughout the actual measurement of 87 engineering designs in the facilities of a national university, and the practical usability of the facilities was investigated by in-depth interviews with eight disabled persons. New design solutions were developed by the anthropometric methodology for better accommodation. The target-specific anthropometry database such as sitting knee height with wheelchair was employed. Results: First, the statistic showed that 28.7% of facility designs comply with the law, 29.9% of facility designs doesn't comply with the law, and 41.4% of facility designs doesn't have related law or regulation. Second, the law of table height(71cm in current) can accommodate only 49.3% of wheelchaired population. The following test for 95% accommodation revealed that the table with 80cm high is required. Third, the current law in the door width(90cm) can only accommodate 82.6% of disabled persons, so the new design solution was calculated and suggested that 100cm in the door width is necessary for 99% accommodation of disabled persons. Conclusion: Even with the laws and regulations for the disabilities it was clear that the accessibility and usability of the disabled persons in everyday facilities was still limited. An investigation for the new solutions about a wide range of facilities is necessary for better practical accessibility and usability of the handicapped persons. Application: The results of current study can be a basement of developing a new guideline or regulation of the facility design for the disabled persons.

Student halls and their convenient facilities have been a focal point for various student activities at university campus. It has been for most of the student a place of unique memories and of attachment often associated with those good and bad school days. However, it is questionable whether these facilities are supportive and accessible for all of the students and other users including the handicapped. Therefore, based on the concept of UD(universal design) which was widely applied to U.S. institutions, this study intended to evaluate student hall facilities in U.S. and to provide an improvement direction for Korean UD application. For that purpose, four universities were selected for an in-depth analysis and 76 survey indices were utilized based on previous research. It was found that (1) design consideration without braille sign for VIP(visually impaired person) in student buildings can be differently approached with electronic devices; (2) the best demonstration of UD in student buildings can be seen in spacious flat pathway, easy access through ramp and wide entry area, necessary for people in wheel-chairs, but used by all, implying an increase of the ratio of public space; (3) one of the good UD features is an attractive physical environment rather than institutional appearance, in which they ultimately will support and completely adaptable at optimal levels by everyone; (4) consistent maintenance and management maximize the potential of UD principles and minimize physical limitations.

The purpose of this study is to propose an curriculum for architectural studio in university to implement BIM process, through the analysis of the advantages of the BIM tool. The limitation of this study was to analyze the case study of only half year a single university. University education in the design process, the design that can be used in applying BIM content should be universal, university education considering the special working conditions, excessive BIM-based application can be difficult. Therefore, a systematic and reliable design that can be applied to education applies BIM design process is necessary to establish. University education applying BIM design review and design proposal the various 3D visualization can be used effectively to determine. In addition, the planned representation for thinking about and drawing 3D model building, architectural space can be used for visualization, and other subjects in conjunction with structural analysis, environmental analysis, facility layout, etc. can be used.

Purpose: Methods for non-destructive estimation of product quality have been reported in various industrial fields, but the application of ultrasonic techniques for the agricultural products of potatoes, pears, apples, watermelons, kiwis and tomatoes etc. have been rarely reported since the application of a contact-type ultrasonic transducer in agricultural products is very difficult. Therefore, this study sought to determine the firmness of apples using non-contact ultrasonic techniques. Methods: For this experiment, an ultrasonic experimental tester using a non-contact ultrasonic transducer was created, and a signal processing program was used to analyze the acquired ultrasonic reflected signal. Also, a universal testing machine was used to measure firmness parameters of the apples such as bioyield strength, a firmness factor, after the ultrasonic tests had been performed. Results: Six distance correction factors were calculated to obtain consistent values of ultrasonic properties regardless of the distance between the transducer and the surface of the subject. We developed prediction models of the bioyield strength using the distance correction factors. Conclusions: The optimum prediction model of the bioyield strength of apples using a non-contact ultrasonic technique was a multiple regression model ($R^2=0.9402$).

Today, the number of the elderly living alone without any family members is on a sharp rise, and those aged people living alone are making these social issues such as solitary death, depression and suicide more popular. In order to resolve the issues, some of the local governments have been supporting the elderly living alone in common houses that would be used by senior citizens only. This study became interested in this 'carnation house' which has been carried out targeting the elderly living alone in Gyeonggi-do, and selected elementary universal design factors that should be applied to general residential environments of the aged people and analyzed the factors. As a case study, this research investigated four carnation houses as research subjects and came up with these following ideas about how to make improvements. First, the study found out that all the entrances did not have raised letters and that UD has not been satisfactorily applied to both the thresholds and the effective widths, and that is considered something to be fixed. Second, in case of regular rooms and living rooms, none of the rooms failed to have safety doorknobs which should have been installed and plus, thresholds and stepped pulleys need to be removed, Third, it goes the same with the kitchens, and the thresholds should be eliminated while cabinets are secured. In addition, furniture that understands the elderly's measurements should be used. Fourth, in terms of restrooms, they should be designed to be spacious enough not to cause anyone in wheelchairs inconvenience, and the study suggests that the effective widths should be widened and that both the safety doorknobs and the emergency calls must be installed. Basically, after the test on the UD adaptability, the study concluded that the application rates in connection with the adaptability were low which led the study to assume that such result has been gained due to the lack of installation standards in relation to the common living facilities of the elderly. The study now argues that purposes of buildings should be first clarified and then, these detailed space planning guidelines that deal with general characteristics of the aged people should be established.
