One of the most performed action in daily life is standing up from sitting position. As the population of the world is aging at the high rates, people may face problems with reduced muscle strength as well as psychological changes. This can lead elderly people having difficulties with standing up from chair. Now, with the aging trend worldwide, products are being developed that can support the lives of the elderly. This study examines the distribution of hip pressure in relation to the seating positions of the standing assistance seats under development to prevent standing up accidents in older adults. The currently developing standing assistant chair designed to tilt to a maximum angle of 25 degrees. At over $25^{\circ}$, design considers that older people are at risk of thrown back out of that force and that the forces exerted on their arms and legs can be a significant burden to older people. By considering danger of higher than $25^{\circ}$ for older people which is experimented in the basis of static capturing approach in previous papers, it is experimented people with age group of 20~60 on $0^{\circ}$ to $25^{\circ}$ tilting angle on the basis of dynamic capturing method in order to pick convenient angle of inclination. Moreover, tried to find the optimum angle by comparing the hip pressure distribution when seated at the edge of the seat and at the center of the seat with the pressure distribution sensor.

A wheelchair is an essential rehabilitation assistant device for the movement of paraplegia patients and generally paralyzed patients who cannot walk normally. In particular, the applicability of the manual/motorized wheelchair is gradually increasing. Until now, decelerators using belt, chain and worm gears, etc have been widely used. However, a decelerator takes a large space although it is a simple device and thus is not ideal for the driving part of manual/motorized wheelchair. For these reasons, in this study we developed a driving part producing a large driving force through a decelerator using planetary gears rather than conventional worm gear-based decelerator. We designed the tooth profile of the planetary gears for decelerator using Kisssoft program, In addition, we designed the driving part so as to apply it to the wheels of conventional wheelchairs, and then optimized the mechanism for the principles of manual/motorized transposition of the driving part and the operational principles. Based on the results of this study, we finally designed and manufactured a driving part for wheelchair decelerator in the form of planetary gears with 1 sun gear, 2 planetary gears and 1 ring gear.

Objectives: Despite greater access to training positions and the presence of more women in emergency medicine, it has remained a men-dominated field. This study aims to identify the key issues causing the gender gap in Korea and establish measures to overcome them. Methods: Using the annual statistical reports of the National Emergency Medical Center and data published on the Korean Society of Emergency Medicine website, cases that listed the current status and positions of members in its organization and its committees were analyzed. Secondary analysis was conducted using data from the 2015 Korean Society of Emergency Survey that included physicians' demographics, academic ranking, years of experience, clinical work hours, training and board certification, core faculty status, position, and salaries. Results: As of September 2019, women account for only 12.7% of the total number of emergency physicians (EP) in Korea; of 119 chair/vice-chair academic positions, women represented only 9.2%. Women EP were more often assistant professors and fellowship-trained, with fewer in core faculty. However, they worked the same numbers of clinical hours as their men counterparts. The median annual salary of women EP was less than that of men EP after adjusting for academic hospital rank, clinical hours, and core faculty status. Conclusions: A gender gap still exists among Korean EP, and women earn less than men regardless of their rank, clinical hours, or training. Future studies should evaluate more data and develop system-wide practices to eliminate gender disparities.

The erection bar is defined as the assistant bar used to fix the position of the reinforcing steel as the reinforcing steel is placed on site. As the erection bar do not bear the structural load and is not showed in the structural drawings, it is not managed importantly. But as chair bars in mat footing is used in large quantities to support the upper main bars, the detailing standards need to be suggested. and some erection bar is placed by experience of the fabricator and placer. Therefore, in this study, a survey about the erection bars was conducted to the reinforcement detailer, the fabricator and placer of domestic construction industry. 11 placing drawings is analyzed to find out the problems of detailing and the quantities of the erection bars. According to the analysis of the survey, the erection bar details in placing drawings were not standardized, and some erection bars are omitted in placing drawings. The improvement in the erection bar detailing was sought by analyzing the results of the survey.

Purpose: The purpose of this study was to investigate whether the respiratory function of patients with stroke was different on the ground and under water. Methods: We recruited 14 adults who had experienced a stroke (12 male, 2 female) for our study. We measured forced vital capacity, forced expiratory volume at one second, maximum inspiratory pressure, and maximum expiratory pressure when the participants breathed on the ground and under water. On the ground, the participants were safely supported using a table and chair and were measured in a standing posture. For measuring under water, the participants were immersed in water in a standing position to clavicle height. The participants were measured while standing, and the assistant supported them when they needed help. The collected data were analyzed by a paired t-test. Results: Forced vital capacity and forced expiratory volume at one second were significantly lower in water than on the ground when breathing at maximum. Maximum inspiratory pressure was not significantly different when standing on the ground or in water, but maximum expiratory pressure was significantly higher in water than on the ground. Conclusion: It has been confirmed that the hydrostatic pressure affecting stroke patients immersed in water affects the forced expiratory volume at one second while reducing the forced vital capacity and increasing the maximum expiratory pressure.

Purpose : This descriptive survey aims to identify the prevalence of factors associated with sarcopenia among hemodialysis patients. Methods : The study subjects were 137 patients with chronic kidney failure undergoing hemodialysis in three artificial kidney centers in B and Y cities. Data were collected from August 1 to September 30, 2020, using the SARC-F (Strength, Assistant walking, Rising from a chair, Climbing stairs, Falls) questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), International Physical Activity Questionnaire (IPAQ-SF), Bioelectrical Impedance Analysis (BIA), and a grip dynamometer. The collected data were analyzed using t-tests, crossover analysis, and logistic regression using the IBM SPSS 23 program. Results : The prevalence of sarcopenia among hemodialysis patients, determined using the SARC-F questionnaire, was 16.1%. The associated factors of sarcopenia among hemodialysis patients were found to be gender (OR=6.44, p =.002), age (OR=1.07, p =.015), nutritional status (OR=10.37, p =.027), and albumin level (OR=0.10, p =.014). These findings are supported by an explanatory power of 46.3% (p =.597). Conclusion : The identified risk factors for sarcopenia in hemodialysis patients were; sex, age, nutritional status, and albumin level. The findings of this study can serve as clinical evidence for the development of an intervention program for preventing and managing sarcopenia in patients undergoing hemodialysis.

장애인들이 많이 사용하고 있는 보조기구 중의 하나인 수동휠체어는 KS규격인 KS P ISO 7176-5의 치수 규격을 따르고 있다. KS P ISO 7176-5의 경우 국제 규격인 ISO 7176-5의 규격을 기술적 변경 없이 그대로 사용하고 있다. 하지만 국제규격의 경우는 외국의 신체사이즈를 기준으로 수동휠체어에 대한 크기를 지정하기 때문에 한국에서 사용하기에는 적합하지 않다. 실제로 기술표준원에서 조사한 인체치수 조사 자료와 현재 KS P ISO 7176-5의 규격을 비교한 결과 팔걸이 높이를 제외한 좌석의 높이, 좌석면의 너비, 좌석면의 깊이, 등받이 높이의 경우 KS P ISO 7176-5의 크기가 컸고, 팔걸이 높이는 KS P ISO 7176-5의 크기가 낮았다. 이러한 경우 사용자가 장시간 사용하게 되면 안정성이 감소되고, 사용자의 골반 회전이 쉬워져서 자세가 불안정해지고, 오금이 좌석의 모서리에 닿아 오금과 장딴지에 압력이 가해지고, 자세가 앞으로 당겨서 앉는 자세가 되어서 등이 구부정한 자세가 된다. 또한 몸이 앞이나 옆으로 기울어지는 자세가 되어서 올바른 자세로 유지할 수 없게 된다. 이러한 문제점이 계속 지속이 된다면 사용자의 신체에 무리가 올 수 있다. 이 논문에서는 한국의 장애인 치수에 대한 조사를 하여 올바른 휠체어 치수를 연구하여 제안하였다.
