Visually impaired people use tactile maps to get spatial information about their surrounding environment, find their way, and improve their independent mobility. However, classical tactile maps that make use of braille to describe the location within the map have several limitations, such as the lack of information due to constraints on space and limited feedback possibilities. This study describes the development of a new multi-modal interactive tactile map interface that addresses the challenges of tactile maps to improve the usability and independence of visually impaired people when using tactile maps. This interface adds touch gesture recognition to the surface of tactile maps and enables the users to verbally interact with a voice agent to receive feedback and information about navigation routes and points of interest. A low-cost prototype was developed to conduct usability tests that evaluated the interface through a survey and interview given to blind participants after using the prototype. The test results show that this interactive tactile map prototype provides improved usability for people over traditional tactile maps that use braille only. Participants reported that it was easier to find the starting point and points of interest they wished to navigate to with the prototype. Also, it improved self-reported independence and confidence compared with traditional tactile maps. Future work includes further development of the mobility solution based on the feedback received and an extensive quantitative study.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.

This study was done to identify basic information in classifying nursing diagnoses and nursing interventions needed for the further development of computerized nursing care plans. Data were collected by reviewing charts of 123 home care clients who had active disease, for whom at least one nursing diagnosis was on the chart, and who had been discharged. Data included demographics, medical orders, nursing diagnoses and nursing interventions. The results of the study, which found the most frequent medical diagnoses to be cancer (40.7%) and brain injury (26.8%), showed that 'Impaired Skin Integrity'(18.3%), 'Risk for Infection'(15.0%), 'Altered Nutrition, Less than Body Requirements'(13.8%), and 'Risk for Impaired Skin Integ rity'(9.9%) were the most frequent nursing diagnoses. 'Pressure Ulcer Care'(28.4%) was the most frequent intervention for 'Impaired Skin Integrity', 'Infection Protection'(16.0%) for 'Risk of Infection', 'Nutrition Counseling'(26.8%) for 'Altered Nutrition' and 'Positioning'(22.0%) for 'Risk for Skin Integrity Impairment', Comparison of interventions with the Nursing Intervention Classification(NIC) showed that the most frequent interventions were in the domain 'Basic Physiological' (33.94%), followed by 'Behavioral'(27.8%), and 'Complex Physiological' (22.6%). Interventions related to teaching family to give care at home could not be classified in the NIC scheme. Examination of the frequency of NIC interventions showed that for the domain 'Activity & Exercise Management', 75% of the interventions were used, but for seven domains, none were used. For the domain 'Immobility Management', 93% of the times that an intervention was used, it was 'Positioning', for the domain 'Tissue Perfusion Management', 'IV Therapy' (59.1%) and for the domain 'Elimination Management', 'Tube Care: Urinary'(54.0%). The nursing diagnoses 'Altered Urinary Elimination' and 'Im paired Physical Mobility' were both used with these clients, but neither 'Fluid Volume Deficit' nor 'Risk of Fluid Volume Deficit' were used rather 'IV Therapy' was an intervention for 'Altered Nutrition, Less than Body Requirements', A comparison of clients with cancer and those with brain injury showed that interventions for the nursing diagnosis 'Impaired Skin Integrity' were more frequent for the clients with cancer, interventions for 'Risk of Infection' were similar for the two groups but for clients with cancer there were more interventions for' Altered Nutrition'. Examination of the nursing diagnoses leading to the intervention 'Positioning' showed that for both groups, it was either 'Impaired Skin Integrity' or 'Risk for Skin Integrity Impairment'. This study identified a need for further refinement in the classification of nursing interventions to include those unique to home care and that for the purposes of computerization identification of the nursing activities to be included in each intervention needs to be done.

The purpose of this study is to examine the degree of community integration of visually impaired people who have the limitation of mobility in comparison with another disabled and to find factors affecting community integration. The data were obtained through telephone interview with visually impaired people. The final sample was consisted of 1,004 respondents. The data were analyzed using statistical techniques such as crosstabulation, t-test, and hierarchical regression. In this study, the factors affecting community integration was divided into four dimensions : the attribution to disability, physical functioning, psychology and social support system. The major findings of this study were as follows: First, the factors affecting community integration of visually impaired people were age, education, economic status, social support, information support and participation of rehabilitation service. Second, the factors affecting community integration of the low vision and the blind are the limitation of daily activities and social support. But the factors affecting community integration of the blind are participation of education for braille and that of the low vision are information support and participation of rehabilitation service. Finally, the person losing eyesight since school age were the more limitation of daily activities than the person losing eyesight in babyhood. The factors affect community integration of the former are social support, information support, participation of education for braille, and rehabilitation service. The current findings suggest that intervention and policy aimed at improving social support system and formal services such as education, rehabilitation services should be considered by rehabilitation professionals and policy makers.

The purpose of this study is to examine urban built environments associated with the walking behavior in order to identify the problem of urban infrastructure from the perspective of Universal design theory. Using the walkability criteria developed based on the findings of previous studies on Universal design theory and walking environment, the urban built environments in old town area of Seoul were evaluated. The results of the evaluation indicated that the pedestrian infrastructure in the study area had several shortcomings to improve in order to provide walking-friendly environments. First, the pedestrian infrastructure for visually impaired people were severely limited. Second, walking traffics in large portion of the street networks were interrupted by a variety of obstacles such as parked cars, signboards, and illegal street shops. Third, there were certain areas where the quality of pavement was not properly managed. In summary, this study provides an empirical data to understand the current situation of pedestrian infrastructure in the urban areas. Improvement of pedestrian infrastructure is needed to address the issues related to the mobility of the disabled people. It is also recommended to construct the GIS data on walking environment in order to develop and mange a long-term public investment plan for walking-friendly urban environments.

Background: Down regulation of major histocompatibility complex class II transactivator (CIITA) has been identified as a major factor of immunosuppression in sepsis and the level of CIITA expression inversely correlates with the degree of severity. However, it has not been fully elucidated whether the lower expression of CIITA is a cause of disease process or a just associated sign. Here we determined whether the CIITA deficiency decreased survival rate using murine sepsis model. Methods: Major histocompatibility complex class II (MHC-II) deficient, CIITA deficient and wild type B6 mice were subjected to cecal ligation puncture (CLP) surgery. CIITA and recombination activation gene (RAG)-1 double deficient mice were generated to test the role of lymphocytes in CIITA-associated sepsis progression. Results: Sepsis mortality was enhanced in CIITA deficient mice, not by impaired bacterial clearance resulted from CD4 T cell depletion, but hyper-inflammatory response such as excessive release of a pro-inflammatory cytokine, high-mobility group box 1 (HMGB1). Conclusion: Our results demonstrate that CIITA deficiency affects the course of sepsis via the unexpected function of CIITA, regulation of cytokine release.

Home nursing interventions based on nursing diagnosis were implemented to the patient who are discharged from one hospital often the treatment for chronic neuromuscular system problem, and its effects were studied. The purpose of this study was to find out the effectiveness of hospital bouned home nursing provided by hospital nurses and to categorize home nursing diagnosis and its interventions. Data from experimental group patients were collected at three different time ; at the time of discharge, two weeks after discharge and our weeks after discharge. Data from controll group patients were collected twice ; the first one at the time of discharge, and the other one four weeks after discharge. For this study nursing assessment and intervention booklet developed by the research team. There were no significant decrease of the number of nursing problems and life satis-faction. But daily activity level of patients showed the signs of significant improvement at the time of four weeks after discharge. Results of this study indicates that home nursing intervention based on nursing diagnosis provided the patients with noticeable difference in health maintanance, impairment of physical mobility, potential for infection, impaired home marntenance management, health seeking behavior, chronic pain, disuse syndrome, impaired skin integrity.

Purpose: The purpose of this study was to develop and to apply the NANDA, NOC, and NIC (NNN) linkages into a computerized nursing process program using the classification systems of nursing diagnoses, nursing outcomes and nursing interventions. Method: The program was developed with planning, analysis, design and performance stages. The program was applied to 117 patients who were admitted to orthopedic surgery nursing units from January to February, 2004. Results: Thirty-five of fifty-three nursing diagnoses were identified. Five nursing diagnoses in order of frequency were: Acute pain $(28.4\%)$, Impaired physical mobility $(15.6\%)$, Impaired walking $(8.7\%)$, Chronic pain $(5.5\%)$ and Risk for disuse syndrome $(5.0\%)$. The nursing outcomes of the 'Acute pain' nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management $(95.2\%)$, Comfort level $(35.5\%)$ and Pain level $(17.7\%)$. The nursing interventions of the 'Acute pain' nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management $(71.0\%)$, Splinting $(24.2\%)$ and Analgesic administration $(17.7\%)$. In comparison of outcome indicator scores between before and after the intervention according to the 61 nursing outcomes, the mean scores of 52 outcome indicators after the intervention were significantly higher than before the intervention. Conclusion: It is expected that this program will help nurses perform their nursing processes more efficiently.

Research and development of Assistive Technology (AT) for blind people is primarily focused on assisting mobility and improving access to information. Some particularly useful devices for aiding access to information and communication are DAISY players used with talking books, screen readers for reading screens, video magnifiers to aid low vision, Braille displays, and Braille PDAs. These essential devices have been successfully commercialized and have assisted many visually impaired people. Assistive technology devices for visually impaired people are called sensory substitution devices, because these devices substitute tactile or auditory functions for visual functions. The tactile interfaces of sensory substitution devices such as Braille displays and Braille PDAs have a bimorph type of piezoelectric actuator that forms a Braille (pin) of the Braille cells by moving up and down. KGS Corporation of Japan has more than 80% share of the worldwide market for these Braille cell actuators. Commercializing it for the first time in the world. This paper reviews the various endeavors in Japan in the research and development of tactile displays, such as Braille displays and Braille PDAs. Furthermore, it discusses sensory substitution devices that use tactile displays, focusing especially on the rotating Braille display we have developed.
