Objectives: The purpose of this study was to identify the factors affecting rehabilitation motivation in hospitalized orthopedic patients. Methods: Data were collected from June 1th to July 31th, 2019 and structured questionnaires were used. Study subjects were 97 orthopedic patients who received fixed treatment more than two weeks and started rehabilitation exercise in a military hospital. The data were summarized using descriptive statistics and analyzed by t-test or one way ANOVA, Pearson's correlation analysis and multiple regression analysis were run in SPSS 20.0 program. Results: The results of this study may be summarized as follows. (1) The demographic characteristics that showed differences in rehabilitation motivation were marital status, age and the ranks of the armed forces. The rehabilitation motivation of married, older than 31, officer ranked soldiers turned out to be higher than those of singles, younger than 30, non-officers, respectively. (2) The results of Pearson's correlation analysis showed that independent variables were all correlated significantly each other. (3) The results of stepwise multiple regression analysis showed that the factors influencing rehabilitation motivation were family social support, medical personnel's social support and the level of military life adaption. Conclusions: The rehabilitation motivation of hospitalized soldiers may be improved by receiving supports from family members and medical personnels and by adapting to military life. Military medical workers need to explore nursing strategies that help hospitalized orthopedic patients increase their own rehabilitation motivation.

Background: Based on the increase in the needs for convalescent rehabilitation medical services in Korea, this study aims to calculate the needs for rehabilitation services and examine its determinants for 229 regions. Methods: Claim data from the Health Insurance Review and Assessment Service were used to estimate patients who need to receive rehabilitation services, and data from various sources were also used for analysis. The number of cases and incidence rates of hospitalization related to convalescent rehabilitation were calculated to estimate the needs for services by region, and the results were visualized via a map. Multivariate regression and fixed effects regression using panel data were performed to identify the determinants of regional variation of the incidence rate. Results: First, the incidence rate of rural areas such as Jeolla-do, Gyeongsang-do, and Chungcheong-do was higher than urban areas (metropolitan cities). Second, the population, proportion of the elder, medical aid recipients, financial independence, traffic deaths, smoking, diabetes rate, and medical infrastructure correlated significantly with the incidence rate. Third, 'rho' values which mean the fraction of variance due to individual terms in panel data regression models were 0.965 and 0.976, respectively. Conclusion: The incidence rate of hospitalizations was correlated with most independent variables in this study and there is a gap between urban and rural areas. These regional disparities are fixed in our society. An improved regional convalescent rehabilitation system is suggested to cover the entire area including rural areas with a high rate of aging.

The aim of this study was to evaluate the effect of exercise-based cardiac rehabilitation on pro- and anti-inflammatory markers in patients with acute coronary syndrome (ACS). ACS patients who underwent percutaneous coronary intervention (PCI) and took medicine during phase II of rehabilitation were recruited for study. Subjects were divided into two groups; exercise group (EX, n=21) and a non-exercise group (non-EX, n=13). Supervised exercise program in hospital consisted of treadmill and bicycle exercise was performed three times per week for 6 weeks. Patients of EX received individual counseling, including knowledge of heart disease, risk factor modification, and physical training. Cardiopulmonary fitness, body composition, and biochemical blood factors were analyzed before and after experiment. There was no significant difference in serum levels of hs-CRP and TGF-${\beta}1$ between groups, and between time intervals. But there was a significant decrease in serum levels of IL-18 (P<.001). And there was a significant increase in ratio of IL-18 to IL-10 (P<.01) and serum levels of IL-10 (P<.001). After cardiac rehabilitation, there was significant increase in exercise duration (P<.001), maximal oxygen uptake ($VO_{2peak}$; P<.001) and decrease in submaximal rate-pressure product (sRPP; P<.05) in EX. In conclusion, exercise-based cardiac rehabilitation during phase II in patients with ACS after PCI decreased serum IL-18 (pro-inflammatory) content and ratio of IL-18 to IL-10 in serum (highly related with disease recurrence), and increased serum IL-10 (anti-inflammatory) content. In addition, it led to improved cardiopulmonary fitness.

Air mattress is now used widely to prevent the pressure ulcer by reducing the localized pressure peaks. In this paper an air-cell mattress and its pressure control method based on an approximate anthropometric model are presented. The air-cell mattress has eighteen cylindrical air cells made of porous material allowing air leakage to contribute in reducing the development of pressure ulcer by lowering the pressure peak, temperature and humidity. To determine an optimal air-cell pressure appropriate for each user, we divide the parts of the body into four sections such as head, trunk, hip, and leg. Then, the pressure of each section is independently calculated from the weight of each part based on the individual body height and weight and the approximate anthropometric model. Air supply system for the air-cell mattress is implemented by using four electronic solenoid valves and an air compressor, and it is driven by a real-time micro-controller. The experimental results with seven subjects shows that the proposed air-cell mattress is effective for the prevention of the pressure ulcer.

Purpose: The emphasis on gait rehabilitation after stroke depends on training support through the lower limbs, balance of body mass over the changing base of support. However, muscle weakness, lack of control of lower limb, and poor balance can interfere with training after stroke. For this case study report, a wearable robot orthosis was applied to stroke patients in order to verify its actual applicability on balance and gait ability in the clinical field. Methods: Two stroke patients participated in the training using the wearable robot orthosis. Wearable robot orthosis provides patient-initiated active assistance contraction during training. Training includes weight shift training, standing up and sitting down, ground walking, and stair up and down Training was applied a total of 20 times, five times a week for 4 weeks, for 30 minutes a day. Gait ability was determined by Stance phase symmetry profile, Swing phase symmetry profile, and velocity using the GAITRite system. Balance ability was measured using the Biodex balance system. Results: Subjects 1, 2 showed improved gait and balance ability with mean individual improvement of 72.4% for velocity, 19.4% for stance phase symmetry profile, 9.6% for swing phase symmetry profile, and 13.6% for balance ability. Conclusion: Training utilizing a wearable robot orthosis can be useful for improvement of the gait and balance ability of stroke patients.

Background and Objectives: The speech-in-noise test is typically performed using an audiometer. The results of the digit-in-noise recognition (DIN) test may be influenced by the flat frequency response of free-field audiometry and frequency of the hearing aid fit based on fitting rationale. This study aims to investigate the DIN test in unaided and aided conditions. Subjects and Methods: Thirty four adults with moderate and severe sensorineural hearing loss (SNHL) participated in the study. The signal-to-noise ratio (SNR) for 50% of the DIN test was obtained in the following two conditions: 1) the unaided condition, performed using an audiometer in a free field; and 2) aided condition, performed using a hearing aid with an unvented individual earmold that was fitted based on NAL-NL2. Results: There was a statistically significant elevation in the mean SNR for the severe SNHL group in both test conditions when compared with that of the moderate SNHL group. In both groups, the SNR for the aided condition was significantly lower than that of the unaided condition. Conclusions: Speech recognition in hearing-impaired patients can be realized by fitting hearing aids based on evidence-based fitting rationale rather than by measuring it using free-field audiometry measurement that is utilized in a routine clinic setup.

Objectives : Ma-huang (Ephedra sinica) is frequently prescribed for obesity management in oriental medicine. The main component is ephedrine alkaloids which can have serious adverse side effects such as heart attack, stroke, sudden death. There are no scientific guidelines for Ma-huang usage in the safe treatment of obesity in oriental medicine. We reviewed published studies on its safety to make evidence based guidelines. Methods : We searched electronic databases up to May 2006. We limited evidence to controlled trials for efficacy or safety, case reports for safety, and studies for Ma-huang contents analysis. Results and Conclusions : In clinical trials for weight loss, Ma-huang and ephedrine promote modest short-term weight loss but have no serious adverse effects, have only a few adverse effects associated with increased risk of psychiatric, autonomic, gastrointestinal symptoms and heart palpitations. In case reports, there have been serious adverse effects including stroke, heart attack, and death using typical doses of ephedrine or no associated illness. There are factors related to serious adverse effects, such as overuse, lack of standardization, individual sensitivity, and interactions with other drugs. Studies relating to these factors should be analyzed for safe use of Ma-huang and ephedrine. After analyzing related studies, we suggest guidelines for Ma-huang usage. We propose that the dosage should be within 4.5-7.5g per day for up to 6 months for generally healthy individual. It's use is contraindicated in individuals with heart disease, thyroid disease, diabetes mellitus, hypertension, psychiatric disorders, glaucoma, urination disorders, enlarged prostate, persons using MAOIs, methyldopa and sympathomimetic agents.
