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.

This paper describes a study on the FRACAS(Failure Reporting Analysis and Corrective Action System)-based dependability control platform for domestic urban railway trains. There are more demands for the verification of the dependability of trains as it becomes a regulation for train manufacturers to verify the dependability recently. Train manufacturers as well as railway operators need a effective FRACAS solution to perform the verification of the dependability. Yet current FRACAS solutions have limitations to support the verification processes effectively. This paper addresses the issues of current FRACAS solutions and suggests a FRACAS framework designed for the domestic urban railway trains. Service failure scenarios are standardized using the proposed availability model to implement a more user-friendly and reliable platform. A new FRACAS-based platform for the dependability control (SCARF^®) has been developed to implement the suggested framework. The detail interfaces and functions of the platform are explained. The SCARF^® platform is expected to engage the increasing demands for the dependability control successfully enhancing the reliability, maintainability, availability and safety of domestic urban railway trains eventually.

The main purpose of this study is to examine the relationship between the variables of infant temperament, maternal emotional availability, infant emotional responsiveness and involvement. A total of 60 infants and their mothers participated in this study. Mother-infant dyads were observed and mothers then completed questionnaires. Data was analyzed by means of descriptive statistics, t-tests, Pearson's correlations and hierarchical regressions. In terms of infant emotional responsiveness, maternal sensitivity and non-hostility, these were revealed to have had an effect on infant emotional responsiveness. Moreover, infants who have mothers who had the ability to read their infants' emotional signals accurately, responded in appropriate ways and interacted with affection, showed a higher level of responsiveness. In terms of infant emotional involvement, maternal structuring had an effect on infant emotional involvement. That is, infants who have mothers willing to support their infants through appropriate guidance and facilitate their interaction were more emotionally involved during the play sessions. In conclusion, maternal sensitivity, non-hostility and structuring were all related to infant emotional responsiveness and involvement, however, the degree of the effects of these variables differed.

In the past few decades, many catastrophic natural disasters have occurred not only in Japan and Korea, but also in other countries in the world, forcing people to live in unfamiliar houses for middle or long range evacuation periods. Residents staying in temporary houses exhibit insomnia, resulting in severe fatigue. In order to investigate sleeping state of residents, measuring vital signals has been performed at examination room of a hospital. To avoid the restriction of residents' movement, we propose to use smartphone and/or wearable devices with various high performance sensors like measuring heart beat rate. We clarify the availability and usefulness of those devices as support for analyzing daily sleeping state of residents.

This paper examines the correlations between user characteristics and their perferences for two selected features of Web-based OPAC systems. User characteristics identified in this study were age, gender, educational status, computer skills and OPAC experience. Usability features included interaction styles, character and image on screen, browsing and navigating style, screen layout, and ease of learning, whereas availability features attended to availability of information, quality of information and up-to-date information. Individual variables and features are described, and the correlation between the variables and the features are explored using Pearson's correlation coefficient(r). Although based on a small-scale sample survey, a considerably large number of statistically significant correlations were found between the users' characteristics and the selected evaluation features of interactive Web-based OPACs. From these observations, it seems to be suitable to recommend that system designers should make a more considered appraisal of the users' demographic characteristics in the design of the new generation of OPAC such as in user-tailored interactive Web-based OPAC systems.

Using samples of working mothers with 0-to-47 month old children extracted from the National Longitudinal Survey of Youth (NLSY), this study investigated effects of mothers' job characteristics on parenting behaviors and young children's motor, social, and cognitive development. Date were analyzed by descriptive statistics and multiple regression analysis. Results indicated that (1) job dissatisfaction was negatively related to children's development. (2) Working fewer hours was positively associated with mothers' cognitively stimulating parenting behaviors. (3) Total earnings were a positive predictor of mothers' emotional support. (4) The availability of a flexible hour benefit was positively related to mothers' cognitive stimulation level but the availability of a paid sick and vacation days combined benefit was negatively related to mothers' cognitively stimulating parenting behavior.

During acute stages of hospitalized stroke patients, family caregivers face many challenges. They often experience emotional distress, social isolation, and financial constraints. However, the burden of caregiving of stroke patients in acute stages has never been studied properly. The purpose of this study was to investigate the factors related to the caregivers' burden with acute stroke. The subjects were 123 acute stroke patients and their caregivers who were admitted to neurology and neurosurgery units at Dan Kook University Hospital in Chung-Nam area. An interview was performed with the use of standardized questionnaire which included data pertaining to the patients/caregivers characteristics, caregiver burden (Modified Zarit's Burden Scale), and social support (Personal Resource Questionnaire). Our results showed that the mean burden score was 3.11, indicating high level of burden. Among the sub-domain scores, financial burden was the highest. In univariate analysis, the factors related to caregiver burdens were: inability to communicate between patients and caregiver(p<.001); low cognitive function of the patients(p<.001); low level of ADL(p<.001); the gender of caregiver(p<.001); the current employment status of caregivers(p<.01); the presence of social support for caregiver(p<.001); and the availability of alternative caregivers(p<.001). In multiple regression analysis, social support for family caregivers (87%), low level of patient's cognition (2%), availability of 2nd caregiver (1%), and gender of caregiver (female, 0.4%) were significant explanatory factors of overall burden. The caregivers' burden in acute stages during hospitalization following stroke was high. Recognition of high levels of caregivers' burden and those relating factors affecting caregiver burden may allow us to develop different nursing strategies to unload the level of burden for caregivers in acute stages of stroke.

The successful operation of a product In service depends upon the effective provision of logistic support in order to achieve and maintain the required levels of performance and customer satisfaction. Logistic support encompasses the activities and facilities required to maintain a product (hardware and software) in service. Logistic support covers maintenance, manpower and personnel, training, spares, technical documentation and packaging handling, storage and transportation and support facilities.The cost of logistic support is often a major contributor to the Life Cycle Cost (LCC) of a product and increasingly customers are making purchase decisions based on lifecycle cost rather than initial purchase price alone. Logistic support considerations can therefore have a major impact on product sales by ensuring that the product can be easily maintained at a reasonable cost and that all the necessary facilities have been provided to fully support the product in the field so that it meets the required availability. Quantification of support costs allows the manufacturer to estimate the support cost elements and evaluate possible warranty costs. This reduces risk and allows support costs to be set at competitive rates.Integrated Logistic Support (ILS) is a management method by which all the logistic support services required by a customer can be brought together in a structured way and In harmony with a product. In essence the application of ILS:- causes logistic support considerations to be integrated into product design;- develops logistic support arrangements that are consistently related to the design and to each other;- provides the necessary logistic support at the beginning and during customer use at optimum cost.The method by which ILS achieves much of the above is through the application of Logistic Support Analysis (LSA). This is a series of support analysis tasks that are performed throughout the design process in order to ensure that the product can be supported efficiently In accordance with the requirements of the customer.The successful application of ILS will result in a number of customer and supplier benefits. These should include some or all of the following:- greater product uptime;- fewer product modifications due to supportability deficiencies and hence less supplier rework;- better adherence to production schedules in process plants through reduced maintenance, better support;- lower supplier product costs;- Bower customer support costs;- better visibility of support costs;- reduced product LCC;- a better and more saleable product;- Improved safety;- increased overall customer satisfaction;- increased product purchases;- potential for purchase or upgrade of the product sooner through customer savings on support of current product.ILS should be an integral part of the total management process with an on-going improvement activity using monitoring of achieved performance to tailor existing support and influence future design activities. For many years, ILS was predominantly applied to military procurement, primarily using standards generated by the US Government Department of Defense (DoD). The military standards refer to specialized government infrastructures and are too complex for commercial application. The methods and benefits of ILS, however, have potential for much wider application in commercial and civilian use. The concept of ILS is simple and depends on a structured procedure that assures that logistic aspects are fully considered throughout the design and development phases of a product, in close cooperation with the designers. The ability to effectively support the product is given equal weight to performance and is fully considered in relation to its cost.The application of ILS provides improvements in availability, maintenance support and longterm 3ogistic cost savings. Logistic costs are significant through the life of a system and can often amount to many times the initial purchase cost of the system.This study provides guidance on the minimum activities necessary to Implement effective ILS for a wide range of commercial suppliers. The guide supplements IEC60106-4, Guide on maintainability of equipment Part 4: Section Eight maintenance and maintenance support planning, which emphasizes the maintenance aspects of the support requirements and refers to other existing standards where appropriate. The use of Reliability and Maintainability studies is also mentioned in this study, as R&M is an important interface area to ILS.

The purpose of this study was to explore the potential development of a communal child care project that would lead towards a more family friendly community. By reviewing the case of the Daejeon Health Family Support Center, the study revealed that many child care providers showed an interest in communal child care. But the providers also had problems seeking both partners for communal child care and a communal place to gather. The Daejeon Health Family Support Center had several elements of strength in communal child care project. First, they provided educational programs for care providers to promote the professional knowledge and skills needed for child care and education. The participants' responses to the program were satisfactory, in that they showed the relative effectiveness of such programs in improving attitudes towards Pumasi, along with customized services and other programs provided by the Healthy Family Support Center. In addition, the availability of professional child care services in the attached gym, the Saturday classes for dual earner families, and the prompt response by the center to requests that more space be provided, also contributed to the success of Pumasi program.
