The purpose of this study was to investigate the fluid balance of the patients who were either on soft fluid diet or total parenteral nutrition. We studied 19 patients with neurologic disorders and 22 patients with oromaxillary surgery who were admitted to either D university hospital in Choognam or S general hospital in Seoul between May and November 1995. The mean age for the patients who had oromaxillary surgery was 24 years and their average hospital stay was 9 days. The mean age of the patients with neurologic disorders was 54 years and they were bedridden for average of 71 days. For the maxillary bone surgery patients we did not limit the range of their activities in the ward during data collection period. The patients with neurological disorders were bedridden and did not move around the ward. They were all either on soft fluid diet, or total parenteral nutrition. The findings of this study are as follows ; 1) The difference of the triceps skinfold thickness between the baseline and the final measurement was 0.4cm for neurologic patient group and 0.5cm for oromaxillary surgery patient group. The difference was not statistically significant in each group. 2) In the oromaxillary surgery patient group, the daily intake of fluid in the form of pure water, other beverages, fluid diet as well as IV fluid was 4581m1 while urine output was 2979ml. The difference between fluid intake and output was statistically significant, indicating that fluid intake was far more than urine output. In neurologic patient group, the daily intake of fluid including water from fluid diet and IV fluid was 2701m1 whereas urine output was 2253m1 and they were statistically significant. 3) For a more accurate assessment we adjusted the fluid balance based on weight changes during data collection period. In the oromaxillary surgery patient group. the difference between fluid intake and output was 1238m1 after weight changes being adjusted. The difference was statistically significant, suggesting fluid overload in this patient group. In neurologic patient group, the difference between fluid intake and output considering weight changes was 124ml. The difference was not statistically significant, suggesting that the fluid intake and output was well balanced in this patient group.

Purpose: Nursing home quality indicators have been focused widely on result outcomes, not for the environment in that quality of service are delivered, This study aimed to examine structural factors influencing quality management activities in nursing homes. Method: Sample was 170 nursing homes responded to the survey questionnaire which was distributed to the 543 nursing homes nation-wide, Data were collected on structural characteristics, types of services, and quality management activities, Data were analyzed with the descriptive statistics, Pearson correlations, and multiple regression. Result: Most of the nursing homes were operated as free of charge by the social welfare ownership. Average number of residents was 52.1 with severe and mild dementia and bedridden status, In terms of quality management activities, 34% of the sample had CQI committee that focused their activities on services delivery process, performance appraisal, record keeping regularly. 30.6% of quality management activities were accounted for by the number of residents with dementia, the ratio of RN to residents, rehabilitation services, and social wefare services in nursing homes. Conclusion: We recommend that more comprehensive quality management activities should be developed as process quality indicators in conjunction with the outcome indicators.

The purpose of this study was to describe the overall physical environment's features of nursing homes for Korean American elders in the United States. This investigation was conducted in Korean American nursing homes on the East Coast and in the Midwest with multiple qualitative data collection methods, such as interviews, observations, document review, and field notes. The findings of this study are as follows: 1) Although almost all respondents were unable to speak and understand English at all, most written materials in nursing homes were in only English; 2) The nursing homes were placed near or within the Korean communities; thus, it contributed to close ties with religious Korean American groups and other groups in the ethnic communities; 3) Whether the facility's physical features looked like those of a hospital or a home, many residents did not consider a nursing homes as a real home; 4) A fenced garden in the nursing home in the Midwest was the residents' favorite public space; 5) Due to being forced to room with residents who had dementia and were bedridden, they were more likely to have conflicts with their roommates and feel uncomfortable living in their room; and 6) The facilities seemed to be designed without consideration to protect residents' privacy.

Many walking stands, and assisting tools have been developed for the people with low-limb disability to prevent diseases from bedridden state and to help them walk again. But many of those equipments require user to have some physical strength or balancing ability. In our last research, we developed walking assist system for the people with lower-limb disability. With the system, user can be assisted by actuators, and do not have to worry about falling down. The system adapted the unique closed links structure with four servomotors, three PICs as controller, and four limit switches as HMI (human man interface). We confirmed the adaptability of the system by the experiment. In this research, Muscle Stiffness Sensor was tested as the advanced HMI for walking assist system, and confirmed the adaptability by the experiment. As Muscle Stiffness Sensor can attain the muscle activity, user can interface with any device he want to control. Experimental result with Muscle Stiffness sonsor showed that user could easily control the walking assist system as his will, just by changing his muscle strength.

This paper proposes a design of controller for automatic evacuation disposal system with suction, collecting, washing, and drying functions to be useful for excretion care of long-term bedridden patients. It is desirable that the system can discriminate excreta such as feces and urine severally, and dispose of them without having additional efforts of caregivers. This paper describes a method to improve the discrimination ability by using multi-sensors, and proposes disposal processes according to the type of excrements. As a result the automatic evacuation disposal system can perform an efficient operation in the excrement care. Experimental results using artificial excrements show the automatic evacuation disposal system is effective and feasible to assist the excrement care.

Background A patient's overall condition sometimes does not allow for the complete removal of a dead eschar or injured slough in cases involving a pressure-injury skin lesion. This frequently occurs in clinical practice, particularly in bedridden and older patients receiving home care or intensive care. Even after debridement, it is also difficult to manage open exudative wounds in these patients. Nevertheless, when a mature or immature eschar is treated without proper debridement, liquefaction necrosis underneath the eschar or slough tends to reveal a large, open wound with infectious exudates. We hypothesized that if the presence of any bacteria under the eschar can be evaluated and the progression of the presumed infection of the subeschar can be halted or delayed without creating an open wound, the final wound can be small, shallow, and uninfected. Methods Using a punch instrument, we performed 34 viable subeschar tissue cultures with a secure junction between the eschar and the normal skin. Results The bacterial study had 29 positive results. Based on these results and the patient's status, appropriate antibiotics could be selected and administered. The use of suitable antibiotics led to relatively shallow and small exposed wounds. Conclusions This procedure could be used to detect potentially pathogenic bacteria hidden under black or yellow eschars. Since subeschar infections are often accompanied by multidrug-resistant bacteria, the early detection of hidden infections and the use of appropriate antibiotics are expected to be helpful to patients.

This paper describes the design of an ankle rehabilitation robot for the force measurement of a severe stroke patient staying in a bed ward. The developed ankle rehabilitation robot was attached to a three-axis force/torque sensor that could detect force Fx, Fz, and torque Tz and measure the ankle rotation force (Fx) exerted on the ankle and the signal force Fz and torque Tz to be used as a safety device. The robot was designed and manufactured for bedridden stroke patients, and the robot program was manufactured to perform the flexibility rehabilitation exercise for ankle bending and to measure the ankle force to judge the degree of rehabilitation. According to the result of the characteristics test of the developed rehabilitation robot, it was safely operated while the ankle-bending flexibility rehabilitation exercise and the emergency situation were performed. Therefore, it is thought that the developed rehabilitation robot can be used for severe stroke patients.

Chronic wounds, pressure sores, lesions, and infections of microbial origin in bedridden, paralyzed, or malnutrition patients remain the object of study of many researchers. A variety of factors behind the development of these disorders are related to the patient's immune system, making it unable to respond effectively to the treatment of the wound. These factors can be properly controlled, giving particular importance to the ethiology and stage of the wound, as well as the time periods corresponding to the replacement of the dressings. The present research reports a novel foam/soft material, ${{\small}L}$-Cys-g-PCL, with an application for decubitus/pressure ulcers, especially for wounds with a difficult healing process due to infections and constant oxidation of the soft tissues. During this work, the interactions between S. aureus and ${{\small}L}$-Cys-g-PCL foam were studied under conditions that simulate decubitus ulcers; namely, pH and exudate. The effects of duration of grafting (1 or 8 h) and pH (7.0 and 8.9) on wettability, surface energy, swelling, and porosity were also evaluated. Results showed an effective microbicidal activity exhibiting an inhibition ratio of 99.73% against S. aureus. This new ${{\small}L}$-Cys-g-PCL soft material showed saftey to contact skin, ability to be shaped to fill in sunken holes (craters) - pressure ulcers stage III - and to act as a smart material responsive to pH, which can be tailored to develop better swelling properties at alkaline pH where exudates are normally higher, so as to address exudate self-cleaning and prevention of desiccation.

The subject of this study is to review the practical approaches of Home Care Services. Included is a brief overview of its nature, providers of Home Care Services, recent history of Home Care Services, and the impact of the national movement toward cost containment in health care. The data used in this study are obtained from the Elderly Program of the Medical Services and other data on the Home Care Services in Japan. With the growing elderly population in Japan, it is to be expected that the medical care expenditure for this sector will continue to increase. With the aim of keeping expenditure for medical care within reasonable bounds, it is essential that this increasing expenditure on the elderly be used effectively. With the Health and Medical Services Law for the Aged was enforced, therefore, remuneration for medical treatment of the elderly and what is known as the staff placement standard at hospital for the elderly were rationalized. In addition to rationalization from the point of view of medical care supply, it is necessary to guarantee the appropriate treatment within the community and at home for those elderly who are bedridden but not in need of hospital care. For this it is required that Home Care Services, such as health services like visiting guidance by public health nurse in hospital of Health Center. So that the elderly can feel secure in receiving treatment within the community and at home, allowances for guidance on leaving hospital and for intermittent nursing and guidance thereafter are to be newly introduced. Home care Services in one aspect of comprehensive health care, it is comprised of health services provided to individuals and families in their homes. Its purposes include promoting, maintaining and restoring health, specifically maximazing independent functioning and minimizing the disabling effects of illness, including terminal illness. Services appropriate to the needs of clients and their families are planned, coordinated, and delivered by providers organized for the delivery of home health care through the use of contractual arrangement, employed staff, or a combination of the two.
