Older drivers have an increased risk of accidents due to poor function, but they also develop self-regulation ability to check their own changes. Thus, information on whether the actual elderly driver responds to changes in driving ability and risk may provide a meaningful basis for the clinic and research of the elderly's driving ability assessment. Therefore, the purpose of this study is to provide basic data for the evaluation of elderly drivers by analyzing the driving risk self-perception characteristics in terms of driving behavior and function with Korean elderly drivers. A self-reporting assessment was conducted on 500 elderly drivers living in the community and the characteristics of driving risk perception were analyzed. As a result, it was confirmed that many elderly drivers are aware of the driving risk when their vision and hearing are impaired or when they find it difficult to adapt to changes in driving conditions. On the other hand, the characteristics of insensitive reactions to changes in medical health conditions, such as drug use or epilepsy, seizures, and loss of consciousness, were identified. The researcher hopes this study will contribute to the safety management of elderly drivers in Korea, where aging is accelerating.

This study investigated the impact of long-term relationship orientation on emotional characteristic in fashion stores and relationship characteristic between middle-aged and senior women and salespeople. This study employed survey method with questionnaire. Data were collected from 579 women who were from the age of forty to seventy. The data were analyzed using statistic methods(SPSS 15.0 and Amos 5.0) such as frequency analysis, cronbach $\alpha$, exploratory factor analysis, second-order confirmatory factor analysis, confirmatory factor analysis and structural equation modelling. The findings of this study were concluded as follows; Firstly, the income significantly affected on emotional characteristics(p < 0.01), but had no significant effect on long-term relationship orientation(p < 0.05). The higher income, the more respondents exhibited positive attitude and sensitive emotional characteristics as a sense of sight, hearing, smell, tactile and feeling to salespeople in the fashion stores. The path of structural equation was implemented as income variables $\rightarrow$ emotional characteristics $\rightarrow$ (relationship with salespeople variables $\rightarrow$ )commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level. Secondly, senior group(55~70yrs) was more positive relationship with salespeople compared to middle-aged group(40~54yrs). The precondition of get satisfaction and feeling of being cared from the salespeople were critical for long-term relationship orientation. The path of structural equation was carried out as age variables $\rightarrow$ relationship with salespeople variables $\rightarrow$ commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level.

The purpose of this study is to discuss the planning direction of educational spaces to support children's healthy and creative learning based on bio_philic theory. This study analyzed the characteristics of the application of biophilic patterns in children's education space through case analysis. The conclusion of this study is summarized as follows. As a result of the analysis of children's classroom space, the pattern of 'A(Visual connection with nature), F(Dynamic & Diffuse Light), K(Prospect)' shows high application rate, but the pattern of 'C(Non-Rhythmic Sensory Stimuli), G(Connection with Natural Systems), I(Material Connection with Nature)' shows low application rate. In particular, there is a lack of connection with patterns such as hearing, smell, touch, taste stimulation and water experience, and curiosity through exploration of nature about 'B(Non-visual connection with nature), E(Presence of Water), N(Risk/Peril)' changes in nature and ecosystem. In the corridor and rest space, the pattern of 'A(Visual connection with nature), D(Thermal & Airflow Variability), F(Dynamic & Diffuse Light), G(Connection with Natural Systems), K(Prospect)' shows high application rate, but 'B(Non-visual connection with nature)' shows low application rate. In addition, the application of patterns related to the stimulation of curiosity through direct exploration of nature and the exploration of the patterns of 'E(Presence of Water), N(Risk/Peril)' is insufficient. Therefore, in the case of classroom spaces, the active use of nature as it is should be considered within the scope that does not cause visual confusion, and it should provide an area that can be experienced through the five senses. And corridors and rest spaces should be designed to introduce more active natural elements as spaces to recover stress caused by learning. In other words, the characteristics of children's education facilities need to be connected between classroom space, corridor, rest space and external space. This study is meaningful in that it analyzes and derives the application characteristics of 'biophilic design' which affects the 'Attention Restoration' of children's educational spaces through foreign cases.

This study is designed to examine characteristics and types of basic landscape design established by 7 local governments in Jeollanam-do and its availability as the index of landscape administration and present a guideline with view landscape plan of local governments. The results of this study are described below. In case of view landscape, while Korean cities have not many historical assets like landmark, they have locational characteristics with mountain or coast in the center or surroundings of downtown. Therefore, since view landscape has many cases of restricting individual property rights as well as having a value as public property of city which makes recognition of sharing city, it is very sensitive problem and establishing guideline of it is needed. But, it was found that view landscape plan of local governments established location of view spot with the nature of relief viewing downtown or coast from high spot. Selection of viewing objects in view plan require deciding an object as the public property of city and big cities require selection from the zone and small cities must select 1~2 spots from the viewpoint of whole downtown. 3~4 view spots of middle and distant views which makes city community centering around the subject of view must be selected through enough discussion and in case of natural landscape, View shaft or visible rays require setting of range that 30% of viewing objects is seen. View spot or viewing objects should be selected over twice as extra spots through public hearing and civil participation as the process.

Purpose: The aim of this study was to explore characteristics of and risk factors for accidental inpatient falls. Methods: Participants were classified as fallers or non-fallers based on the fall history of inpatients in a tertiary hospital in Seoul between June 2014 and May 2015. Data on falls were obtained from the fall report forms and data on risk factors were obtained from the electronic nursing records. Characteristics of fallers and non-fallers were analyzed using descriptive statistics. Risk factors for falls were identified using univariate analyses and logistic regression analysis. Results: Average length of stay prior to the fall was 21.52 days and average age of fallers was 61.37 years. Most falls occurred during the night shifts and in the bedroom and were due to sudden leg weakness during ambulation. It was found that gender, BMI, physical problems such elimination, gait, vision and hearing and medications such as sleeping pills, antiarrhythmics, vasodilators, and muscle relaxant were statistically significant factors affecting falls. Conclusion: The findings show that there are significant risk factors such as BMI and history of surgery which are not part of fall assessment tools. There are also items on fall assessment tools which are not found to be significant such as mental status, emotional unstability, dizziness, and impairment of urination. Therefore, these various risk factors should be examined in the fall risk assessments and these risk factors should be considered in the development of fall assessment tools.

As the technical medium evolves, the method of accepting information is changing. The technical medium also appears in various ways through the combination with art. This study aims to conduct research on how hypermedia, appearing from this, will reveal itself in the urban public design in terms of its expression mode. First, this study looks at the characteristics for expression representation of hypermedia art through theoretical considerations on the hypermedia. Second, this study identifies how hypermedia art is introduced in the urban public design through art cases. Third, this study reveals the characteristics depending on the expression mode of hypermedia art shown in the urban public design based on the analyzed cases. As a result, first, hypermedia appeared in various image lighting expression modes that use 'light' in the urban public design and interacted with the public. Second, hypermedia reacted to 'motion' and was the expression mode of using bodies in the urban public design and using peripheral devices and external environment and characterized by having complex patterns of multi-layered structure through multi-media. It also applied sight, hearing, and touch partially or integratedly to attract synesthesia from the public and checked mutual interaction rapidly in an improvised way. Third, such a complex digital technology was the network expression mode beyond space and time by medium of urban public design and characterized by the new experience of virtual space expansion through the world wide network and the communication mode of participation. With such a role change of media and combination with art, hypermedia has been achieving varied extended representations. It is considered to change our monotonous urban environment, restore our relationship with the public, and open a new field of communication. Accordingly, the significance of this study can be identified through how it aimed to display the expression method of hypermedia which caused its extension in the field of urban public design as well as through the derivation of relevant characteristics.

Purpose : The aim of this study was to investigate the differences in sociodemographic characteristics, instrumental activities of daily living (IADL), and healthcare needs among disabled persons with and without language disorder. Methods : Using raw data from the National Survey of the Disabled Person (2017), this study compared 6,320 disabled persons without language disorder and 229 disabled person with language disorder among 6,549 persons with disabilities. The dependent variables included sociodemographic characteristics, IADL, and healthcare needs. Results : People with language disorder were younger (p<.001), illiterate (p<.001), and had higher family income (p=.003) than people without language disorder. In addition, people with language disorder had a higher disability grade than people without language disorder (p<.001), and the percentages of brain injury, hearing impairment, and intellectual disability were higher among type of disability (p<.001). People with language disorder showed significantly higher dependence on all items of IADL than people without language disorder (p<.001). As the first-ranked healthcare need, people without language disorder had the highest percentage of "chronic illness management," and people with language disorder had the highest percentage of "disability management" (p<.001). Conclusion : The findings of the current investigation suggest that health care services are needed to improve IADL in people with language disorder and that the development of a disability management program for people with language disorder is required.

PURPOSE: This study examined the status of the efficient supply of assistive devices for students with disabilities. METHODS: A complete investigation was conducted on the request and supply of assistive devices for students with disabilities at the Korea National University of Welfare. The subjects were 112 students with disabilities who applied for assistive device rental. The status of the supply of assistive devices according to the type of disability was investigated. The overall satisfaction with learning support was measured. The questionnaire content was categorized into the following three factors to determine learning support satisfaction: support overall (role, staff, facilities) learning support (learning support, learning counseling, life consultation), assistive device supply (counseling, rental, uses, rental period, maintenance services). RESULTS: The most common type of students with disabilities was physical disabilities 62 (29.38%) and hearing impairments 62 (29.38%). Students with physical disabilities and brain lesions rented manual and electric wheelchairs the most. Learning support satisfaction was evaluated considering the factors support overall, learning and assistive device supply effects. satisfaction of learning support for students with disabilities 83.5 points. CONCLUSION: The satisfaction with assistive device supply appears to be relatively lower than support overall. Each university will gradually secure assistive devices that suit the characteristics of students with disabilities.

With the development of medical technology, interest in rehabilitation devices is increasing and various devices are being studied. In particular, devices for speech disorders such as hearing impairment and cleft palate are attracting attention. In general, the nasometer is used for patients with flaccid dysarthria and velopharyngeal incompetence(VPI). However, in the case of the conventional separator type nasometer, that has an acoustic feedback problem between the oral and nasal sounds. In recent, the mask type nasometer has been developed which is insensitive to acoustic feedback. But, still not popularized. In this paper, the nasometer characteristics of the conventional separation type and mask type are analyzed. Also, We were obtained clinical acoustic data from the 6 subjects and examined the significant differences in the structure of the separation type and mask type nasometer. Through experiments, it was confirmed that the measurement was about 3~15% higher in the mask type nasometer than the conventional nasometer having a separator type. Also, We was considered the necessity of nasometer signal processing for acoustic feedback reduction and nasalance calculation optimization.
