This study evaluated the community-based rehabilitation services provided by the Wonju Public Health Center from Jan. 2000 to Dec. 2002. Ninety-four persons with disabilities dwelling in the community participated and the surveys were completed in an interview during home visits. The respondents' demographic, socio-economic, and medical characteristics, rehabilitation service received, willingness to receive home-visit rehabilitation services, and satisfaction with the rehabilitation services were analyzed by frequency and percentage. A Likert scoring system consisting of five agreement-disagreement categories was applied to each item, consisting of Very Satisfied, Satisfied, So-So, Poorly Satisfied, and Very Poorly Satisfied. The major findings were as follows: 1) The rehabilitation services used included medical rehabilitation (26.9%), followed by social assistance (23.5%), diagnosis by a physician at home (17.3%), medical examination (12.3%), housekeeping services (6.2%), and vocational and educational rehabilitation (3.5%). 2) Of the medical services, the respondents desired physical therapy at home and free rental of rehabilitation equipment, such as wheelchairs, canes, walkers, the most, followed by home visit occupational therapy, nursing services, and oriental medicine service in descending order. 3) Some of the respondents expressed so-so satisfaction (50.0%) or dissatisfaction (16.9%) with the rehabilitation services provided by the Wonju Public Health Center. These findings should prove useful when planning or extending community-based rehabilitation programs for the homebound disabled in the community.

Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

Ubiquitous computing environment means the computing environment that has taken its position so closely with the ordinary living so much like air or water. In building up the U-Korea, one of the important issues is the social issue from the drasticincrease of senior population. The contemporary society has its distinct trend in increase of senior household following the nuclear family orientation, increase of working parents with the advancement of women in society, unable to support seniors for long distance or short distance of business trip and other reasons that the need of senior welfare has been ever more felt. Accordingly, the Ministry of Government Affairs and Home Administration has developed the wireless paging system to make prompt response system for 119 Rescue when the single senior is encountered with emergency situation that is has been widely provided for the socially neglected people such as single senior, the disabled persons and others. Currently, the wireless paging system is operated as the sub-system for emergency rescue informationsystem, but due to the lack of reliability of product, problems of terminal portable transmitter, receptor and others, rejection of beneficiary and lack of knowledge in use, insufficient management and supervision of managing officers, the efficiency has been declined that there is a need of development for the system. Therefore, this study proposes the context aware information structure of the subject of ubiquitous wireless paging system required forthe development of the wireless paging system model of ubiquitous environment that improved the problems of currently operated wireless paging system.

In this paper, we proposed a technique to recognize three states in stance phase of gait cycle. Walking assistive devices are used to help the elderly people walk or to monitor walking behavior of the disabled persons. For the effective assistance, they adopt an intelligent sensor system to understand user's current state in walking. There are three states in stance phase; Loading Response, Midstance, and Terminal Stance. We developed a foot pressure sensor using 24 FSRs (Force Sensing/Sensitive Resistors). The foot pressure patterns were integrated through the interpolation of FSR cell array. The pressure patterns were processed to get the trajectories of COM (Center of Mass). Using the trajectories of COM of foot pressure, we can recognize the three states of stance phase. The experimental results show the effective recognition of stance phase and the possibility of usage on the walking assistive device for better control and/or foot pressure monitoring.

The patient who has congenital hypothyroidism and pseudohypoparathyroidism could have mental retardation even though adequate hormone treatment and cannot endure conventional dental treatment. In this case, general anesthesia is selected to administer effective dental treatment. But, there could be symptoms such as anemia, neuropathy, associated pituitary or adrenal hypofunction, cardiac failure even in euthyroid state. And, bradycardia, mental dullness, hypothermia, slow reflexes can appear in case of inadequate thyroid hormone replacement. Especially, macroglosssia, slow drug metabolism, exaggerated responses to anesthetic agents and decreased ventilatory responses could be problem during general anesthesia. The presentation of hypoparathyroidism also varies depending on the chronicity of the result of hypocalcemia. Muscle spasms/tetany, paresthesias, and seizures may occur in an acute onset. Chronic hypocalcaemia causes fatigue, muscle cramps, lethargy, personality changes, and cerebration defects.

Purpose: Clinical nurses are the ideal health care providers to advocate for vulnerable and underserved populations such as people with disability. This study aimed to understand factors influencing nursing advocacy for people with disability among clinical nurses. Methods: The subjects of this study were 186 clinical nurses who were working in three hospitals in B and D cities. Self-report questionnaires were used to collect the data. Data were analyzed using IBM SPSS Statistics 25 with descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results: Clinical experience and esthetical nursing competency have positive correlations with nursing advocacy, and optimism-human rights has a negative correlation with nursing advocacy. Factors influencing nursing advocacy for people with disability were identified as patient directivity (β=0.36, p=.001), optimism-human rights (β=-0.18, p=.008) and clinical experience (≥10) (β=0.14, p=.036). The final model consisting of these factors explained 19% of the variance of nursing advocacy (F=14.99, p=.001). Conclusion: The findings of this study indicate the importance of developing and implementing nursing interventions that can improve patient directivity and optimism-human rights toward people with disability among clinical nurses. These nursing advocacy interventions can be provided as part of continuing education as well as the nursing curriculum.

In this paper, we developed bio-signal based eye tracking system using electrooculogram (EOG) and electromyogram (EMG) which measured simultaneously from same electrodes. In this system, eye gazing position can be estimated using EOG signal and we can use EMG signal at the same time for additional command control interface. For EOG signal processing, PLA algorithms are applied to reduce processing complexity but still it can guarantee less than 0.2 seconds of reaction delay time. Also, we developed dual machine learning structure and it showed robust and enhanced tracking performances. Compare to conventional EOG based eye tracking system, developed system requires relatively light hardware system specification with only two skin contact electrodes on both sides of temples and it has advantages on application to mobile equipments or wearable devices. Developed system can provide a different UX for consumers and especially it would be helpful to disabled persons with application to orthotics for those of quadriplegia or communication tools for those of intellectual disabilities.

Recent advances in medical science have made people live longer, which has affected many aspects of life, such as caregiver burden, increasing cost of healthcare, increasing number of disabled and depressive disorder persons, and so on. Researchers are now focused on elderly living assistance services in smart home environments. In recent years, assisted living technologies have rapidly grown due to a faster growing aging society. Many smart devices are now interconnected within the home network environment and such a home setup supports collaborations between those devices based on the Internet of Things (IoT). One of the major challenges in providing elderly living assistance services is to consider each individual's requirements of different needs. In order to solve this, the virtualization of physical things, as well as the collaboration and composition of services provided by these physical things should be considered. In order to meet these challenges, Web of Objects (WoO) focuses on the implementation aspects of IoT to bring the assorted real world objects with the web applications. We proposed a semantic modelling technique for manual and semi-automated service composition. The aim of this work is to propose a framework to enable RESTful web services composition using semantic ontology for elderly living assistance services creation in WoO based smart home environment.
