Finding solutions for the disabled is a major challenge for our society. In the case of a disability due to a malfunction of the nervous system, the origin may be accidental, genetic, or induced by environmental factors. This type of loss can cause loss or movement disorders (paraplegia, hemiplegia, quadriplegia, epilepsy, Parkinson's disease, multiple sclerosis, etc.) or malfunction of certain sensory functions (blindness, deafness, chronic pain, etc.). Many alternatives, more technology, have been imported to create interfaces between the human body and an artificial prosthesis in order to restore some functions of the human body. A wireless system, battery neurons probe was developed for one hand reading neural signals in the brain, and on the other hand also able to excite the neuron in the brain using a surface acoustic wave one ports (SAW) delay line reflection.

Purpose: The number of people with disabilities and the elderly over 65 years of age is gradually increasing due to physical disabilities and social aging. Their typical physical disorders or chronic diseases include low back pain, sciatic pain, arthritis, and musculoskeletal systems such as discs. The average prevalence of disease is 78%. These are various physical obstacles and hindrances in daily life. Research design, data and methodology: From August 6, 2019 to September 24, 2019, the Senior Welfare Center in Gyeyang-gu, Incheon, operated a healthy body exercise and health education program for living health management. Results: The vascular health index using U-Bio pulse wave was relatively good at the first average of +7.4, but the second average of -6.3. This can be seen as a result of the combination of diet and lifestyle education along with the effect of corrective exercise. As a result of body shape measurement analysis, the number of persons requiring management with 3 or more body imbalances was found to be from 75% before to 62.5% afterwards. Conclusions: Exercise effect appears when exercise lasts for at least 10 weeks. Some performances were good, but there were limitations due to the operation of a short training period.

Purpose: The aims of this study were to describe general characteristics and needs of home health care, and to find the differences between home health care needers and non-needers. Method: In this study, 642 subjects participated who lived in Muan, Jollanam-do. Data were collected in August 2001 using a self-reported questionnaire. The questionnaire was a revised and simplified form of the Organization of Community Health System Program at the Seoul National University. Collected data were analyzed through Kruskal-Wallis test. t-test. and Chi-squire for cross-sectional analysis. Result: The average age of the subjects was 52.6 years and 33.3% of them aged over 65 years. Twenty six percent of them had chronic degenerative diseases. The percentages of hypertension patients and D.M. patients were 6.4% and 2.5%, respectively. The number of family members was 2.95 on the average, 2.19 in cases of families with the elderly and 3.33 in cases of families without the elderly. The rate of disability of the elderly was 10.5%. Marital status (p=.000), the number of family members (p=.000), education (p=.000), job (p=.000) and health insurance (p=.027) were significantly different between home care needers and non-needers. Home care needers had less living expenses (p=.001), more frequent hospital admissions (p=.004), higher chronic disease rate (p=.000) and more frequent visits to public health center (p=.027) than non-needers. Home care needers who wanted free service were twice as many as non-needers. Conclusion: Home care need was very high in rural areas and the needers had worse characteristics (low educational level. low income, no job and no family). Therefore, it is necessary to develop cheaper and more accessible services for home care needers in rural areas.

Purpose: This study was conducted to assess the effects of a personalized nutritional intervention program on food security and health and nutritional status of elderly people in the city of Seoul. Methods: A total of 372 elderly adults aged 65 years or above who resided in Seoul were enrolled in this study. Personalized supplementary food supply and nutritional education based on chronic disease status, disability and cooking ability were implemented for 4 months. To evaluate the effectiveness of the program, nutrient intake, food security status, anemia status, chronic disease management, and frailty status, and prevalence of malnutrition (Mini Nutritional Assessment) were examined. Results: After the program, all subjects displayed significantly increased nutrient intake. Before the intervention, all subjects were in a state of food insecurity; however, after the intervention, 37.1% of the subjects were food secure. Moreover, the rates of being at risk of malnutrition and malnutrition in subjects were decreased and instead rate of those who improved to normal increased to 29.8% from 0% of normal rate before the prevention. The rate of subjects without anemia increased from 18.7% to 28.5% after the intervention. In addition, the rate of subjects with intensive or periodic management of chronic diseases decreased, while those with occasional management of chronic diseases increased from 0% to 4.6%. Furthermore, the rates of being at risk of frailty and frailty were decreased and the normal rate increased from 0% to 9.7% instead. Age group-based analysis showed that elderly people over 80 years showed less improvement in the management of the chronic disease status and the frailty status. Conclusion: Personalized supplementary food supplies and nutritional education improved not only the nutritional status but also disease status in vulnerable older adults, and the effects were more significant in adults aged less than 80 years.

We need to understand the outcomes into adulthood for survivors born either extremely low birthweight (ELBW; <1,000 g) or extremely preterm (EP; <28 weeks' gestational age), particularly their blood pressure and cardiovascular metabolic status,respiratory function, growth, psychological and mental health performance, and functional outcomes. Blood pressure is higher in late adolescence and early adulthood in ELBW/EP survivors compared with controls. In some studies, expreterm survivors have higher insulin and blood lipid concentrations than controls, which may also increase their risk for later cardiovascular disease. ELBW/EP survivors have more expiratory airflow obstruction than do controls. Those who had bronchopulmonary dysplasia (BPD) in the newborn period have even worse lung function than those who did not have BPD. As a group, they are unlikely to achieve their full lung growth potential, which means that more of them are likely to develop chronic obstructive airway disease in later life. Although they are smaller than term born controls, their weight gradually rises and ultimately reaches a mean z-score close to zero in late adolescence, and they ultimately attain a height z-score close to their mid-parental height z-score. On average, ex-preterm survivors have intelligence quotient (IQ) scores and performance on tests of academic achievement approximately 2/3 SD lower than do controls, and they also perform less well on tests of attention and executive function. They have similar high rates of anxiety and depression symptoms in late adolescence as do controls. They are, however, over-represented in population registries for rarer disorders such as schizophrenia and Autism Spectrum Disorder. In cohort studies, ex-preterm survivors mostly report good quality of life and participation in daily activities, and they report good levels of self-esteem. In population studies, they require higher levels of economic assistance, such as disability pensions, they do not achieve education levels as high as controls, fewer are married, and their rates of reproduction are lower, at least in early adulthood. Survivors born ELBW/EP will present more and more to health carers in adulthood, as they survive in larger numbers.

Objectives: After many national physical activity guidelines have established, recent changes are deep and rapid. So the major features and implication to reverse worsening Korean physical activity indicator is desprate but related knowledge and informations are few. So review of recent features and implications of new physical activity guidelines have made. Methods: National physical activity guidelines of advanced countries were searched through snowballing methods. Major features were described according to the nation. Implication were drew through discussion for Korean realitiy. Results: New Australian physical activity and sedentary behaviour guideline explicitly included sedentary behaviour. The age in the guideline expanded to early years. Canada also presented 24-hour movement guidelines to early years. The second generation of the physical activity guidelines reflects the extensive amount of new knowledge. New aspects include discussions of additional health benefits related to brain health, additional cancer sites, and fall-related injuries; immediate and longer term benefits for how people feel, function, and sleep; further benefits among older adults and people with additional chronic conditions; risks of sedentary behavior and their relationship with physical activity; elimination of the requirement for physical activity benefits to occur in bouts of at least 10 minutes; and tested strategies that can be used to get the population more active. Conclusions: The most important message from the new guidelines is that the greatest health benefits accrue by moving from no, to even small amounts of, physical activity. Multiple studies demonstrate that the steepest reduction in disease risk occurs at the lowest levels of physical activity. People need to understand that even small amounts of physical activity are beneficial and that reductions in the risk of disease and disability occur by simply getting moving. So various evidence based proven strstegies are needed in Korea including workforce training.

Rheumatoid arthritis is a systemic disease with chronic progress, but the recent rapid developments of drug treatments have led many patients to gain control of their disease activity. As a result, surgery has been performed less commonly on the wrist or hand than in the past. On the other hand, surgical treatment is still essential to patients who do not respond to those medications. For the successful treatment of symptomatic deformed joints or functional disability, surgeons should understand that the pathology of rheumatoid arthritis proceeds differently in every patient. Furthermore, because rheumatoid arthritis often invades multiple joints in the hand and wrist, the patients often require multiple operations simultaneously. This paper summarizes the current concepts of surgical treatment of rheumatoid arthritis in the hand and wrist based on more than 30 years' experience of our senior surgeon and a literature review.

Background: Depression is a frequent comorbid disease of chronic pain patients. This study was conducted to evaluate the prevalence of depression and to correlate associated factors and depression in patients with lumbar spinal stenosis. Methods: The data of this survey was collected from 97 patients that visited our pain clinic for the management of lumbar spinal stenosis. Depression was examined by a self-reported survey using the Korean version of the Beck Depression Inventory (BDI). The Oswestry Disability Index (ODI) and the life satisfaction scale score were also obtained. Demographic and clinical characteristics (including spouse status, employment status, smoking status, the number of patients with multiple painful areas, the number of patients with combined disease, pain duration, visual analogue scale, Roland 5-point scale and walking distance) were obtained from an interview with the patient. The patients were divided into group N ($BDI{\leq}14$, n = 43) and group 0 (BDI > 14, n = 54) according to the BDI scale. Of the 97 patients, 55,7% had a high BDI score. Results: The patients in group N had a higher rate of employment (48.0%, P < 0.05) and had higher life satisfaction scale scores ($9.4{\pm}2.5$, P < 0.01) as compared to group D patients. The BDI score showed a close correlation with employment status and the life satisfaction scale. Conclusions: Many lumbar spinal stenosis patients had high BDI scores. Employment status and the life satisfaction scale were closely correlated with the BDI score.

A 36 year old blindman, engineer was admitted with chief complaints of hemoptysis, recurrent sore throat, pyoderma in genital organ, uveitis and thrombophlebitis for 10 years. Above the chief complaints were remission or exacerbation during hospitalization. Physicalexamination showed that left radial, ulnar & brachial pulse was not palpable. No bruit or murmur was obtained over the mass. Neurologic examination revealed no significant finding.On admission, chest P-A showed hen egg sized round & oval compact hazy density on left upper lung field. Bronchogram revealed no pathological finding and Lt. tomogram showed well define large,ovoid mass density in the superior mediastinum. Fluoroscopy finding showed nonpulsatile on left upper lung field. Pre-op. aortography was not taken, under the impression of lung Ca. rule out .sortie aneurysm, exploratory operation was performed through the 2nd intercostal space, Lt. It was performed that the mass was ascending sortie aneurysm of saccular type. Direct aneurysmectomy with multiple figure of eight suture were done without any prosthetic graft. Post-op. control I.V.C graphy showed completely obstruction sign. Postopcontrol aortography revealed good surgical result. Final, histopathological answered non-specific sortie aneurysm, saccular type. Post-op. courses were uneventful except mild neurologic disturbance with subclavian steal syndrome and associated with both lower leg pitting edema due to inferior vena cava obstruction. After op, 3 month later, discharged to home, with big systemic problem. Behcet`s syndrome reviewed with related literatures. The coexistence of mouth and genital ulceration with hypopyon mentioned by hippocrates and described by various workers in the early part of this century was first defined as a syndrome by Behcet in 1937. In 1937 Behcet described a chronic relapsing triple symptom complex of oral ulceration, genital ulceration, and ocular inflammation. The place of the syndrome as part of a systemic disorder in now clearer, and the under lying pathology appears to be a vasculitis. The disease runs a- chronic course, blindness being the greatest disability and control nervous system involvement a cause of death. Thrombophlebitis is fairly frequent, france et al [1951] giving an incidence of 25% and Dowling [1961] 12%, superficial thrombophlebitis migrans and thrombosis of large veins, including venae cavae [Thomas, 1947: Boolukos 1960] are recorded. Little attention has been paid to arterial involvement. Mishima et al. [1961] described resection cf an aortic aneurysm in a 38 year old man with Behcet`s syndorme. Mounsey in a clinicopathological conference described a case [Brit, med. J., 1966] of ruptured aortic aneurysm in Bechcet`s syndrome treated by aorto-iliac graft. Also, Shikano and Oshima et al [1963] recorded two aneyrysm of smaller arteries. Unfrequently, aortic aneurysm was presumed to be secondary to osteomyelitis of the lumber spine, though the possible association between aortic aneurysm and Behcet`s syndrome was raised. A further case is reported here, in which ascending aortic aneurysm with Behcet`s Ds. appeared to form part of this generalized disease. This is a case report of surgical experience of Behcet`s Ds. with ascending aortic aneurysm which had nearly all the typical clinical features. Above mentioned and was reviewed with related literatures.

Background : Dyspnea and a limitation in exercise performance are important cause of disability in patients with chronic obstructive pulmonary disease(COPD). A depleted nutritional state is a common problem in patients with a severe degree of chronic airflow limitation. This study was carried out to assess the factors determining the maximum exercise capacity in patients with COPD. Methods : The resting pulmonary function, nutritional status, and maximum exercise performance was assessed in 83 stable patients with moderate to severe COPD. The nutritional status was evaluated by bioelectrical impedance analysis. Maximum exercise performance was evaluated by maximum oxygen uptake($VO_2max$). Results : Among the 83 patients, 59% were characterized by nutritional depletion. In the depleted group, a significantly lower peak expiratory flow rate(p<0.05), Kco(p<0.01) and maximum inspiratory pressure(p<0.05), but a significantly higher airway resistance(p<0.05) was observed. The maximum oxygen uptake and the peak oxygen pulse were lower in the depleted group. The $VO_2max$ correlated with some of the measures of the body composition : fat-free mass(FFM), fat mass(FM), body mass index(BMI), intracellular water index(ICW index), and pulmonary function : forced vital capacity(FVC), forced inspiratory vital capacity(FIVC), diffusion capacity(DLCO) : or maximum respiratory pressure : maximum inspiratory pressure(PImax), maximum expiratory pressure(PEmax). Stepwise regression analysis demonstrated that the FFM, DLCO and FIVC accounted for 68.8% of the variation in the $VO_2max$. Conclusion : The depletion of the FFM is significant factor for predicting the maximum exercise performance in patients with moderate to severe COPD.
