The purpose of this study is to figure out family member's perceptions of side rail use in geriatric hospital by Cavanagh's content analysis with in-depth interview. This finding of the study suggests that the six themes of these perceptions are precautionary safety supervision, movement convenience, ritualistic nursing, physical restraint, danger of wounds, and alternative methods in an older person ward, and that the cause of recognized perceptions is not based on actual events, but rather on relatives' perceived protective value. With the transition of medical industry environment, there is a significant emphasis on efficacy and effectiveness of practice, risk management and evidence-based practice. However, the issue of side rail use and physical restraints remains unsolved in care of older people. Nurses claim the necessity of regimented protocol and clarification from professional organization regarding the side rail use.

This study was conducted to identify families' perception and attitude toward application of physical restraint(PR) in general neurological wards. The study is based on subjects from 70 family members who have cared patients applying PR. Data was collected using self-report questionnaires and reviewing of patients' medical records. 68.6% of subjects were female and the mean age was 47.9 years old. Family members were either sons, daughters or spouses. The questionnaires analyzed families' perceptions based on a score of 5, the results showed a mean score of 4.2, and items related to maintaining therapeutic tools scored the highest. The application of PR with two hands was perceived by families as more important than PR applied with one hand. In families' attitude toward PR, there was general agreement that families had the right to decide to apply and remove PR. Continuous education and information regarding PR is required to support families.

Purpose: The purpose of this study was to understand the experiences of final-year undergraduate nursing students in observing the use of physical restraints on patients in the course of clinical practice. Methods: Three focus group interviews were conducted with 12 Korean nursing students who could provide sufficient information about their observation of physical restraints. The collected data was analyzed through conventional content analysis. Results: The data were classified into four theme clusters, and nine themes. The four theme clusters included 'recognized as an unavoidable means,' 'experienced problems with the use of physical restraints,' 'realized the importance of the nurse's role and efforts,' and 'aspire to learn about correct use of physical restraints.' While nursing students recognized the necessities and problems of using physical restraints in clinical practice, and the importance of nurses' role and effort, the results found that education related to the use of physical restraints should be more systematic within the nursing curriculum. Conclusion: This study highlights the necessity of educating nursing students to ensure they acquire accurate knowledge and awareness regarding the use of physical restraints, and suggests the inclusion of systematic guidelines through simulation or extracurricular activities.

Purpose: The purposes of this study were to develop an educational program to reduce the use of physical restraints for caregivers in geriatric hospitals and to evaluate the effects of the program on cargivers' knowledge, attitude and nursing practice related to the use of physical restraints. Methods: A quasi experimental study with a non-equivalent control group pretest-posttest design was used. Participants were recruited from two geriatric hospitals. Eighteen caregivers were assigned to the experimental group and 20 to the control group. The data were collected prior to the intervention and at 6 weeks after the intervention through the use of self-administered questionnaires. Descriptive statistics, $\chi^2$ test, Fisher's exact probability test, and Mann-Whitney U test were used to analyze the data. Results: After the intervention, knowledge about physical restraints increased significantly in experimental group compared to the control group. However, there were no statistically significant differences between the groups for attitude and nursing practice involving physical restraints. Conclusion: Findings indicate that it is necessary to apply knowledge acquired through educational programs to nursing practice to reduce the use of physical restraints. User friendly guidelines for physical restraints, administrative support of institutions, and multidisciplinary approaches are required to achieve this goal.

This study was undertaken to identify knowledge, attitude, perception and nursing practice toward use of physical restraints, among nurses in long-term care hospitals. We further explored the impact of factors associated with nursing practice toward use of physical restraints. This was a cross-sectional descriptive study in which self-administered questionnaires were collected from 128 nurses working at 11 long-term care hospitals. Descriptive statistics, including t-test, one-way ANOVA, Welch's test, Pearson correlation coefficients and multiple regression, were applied to analyze the data collected. Our results reveal that the participants possess moderate levels of knowledge, attitude, perception and nursing practice toward use of physical restraints. Significant positive correlations were observed between nursing practice and knowledge. Multiple regression analysis showed that the factors significantly related to nursing practice and use of physical restraint were knowledge (${\beta}=0.27$, p=0.002) and attitude (${\beta}=-0.17$, p=0.044), having a total explained variance of 9.0%. The findings from this study suggest that knowledge is the strongest predictor on nursing practice toward use of physical restraints. Thus, we propose that developing and applying evidence-based educational intervention programs to reduce the use of physical restraints in long-term care hospitals are required.

This paper reviews physiological changes in the nervous system of patients with hemiparesis that may contribute to muscle weakness. The discussion includes the important role that alterations in the physiology of motor units, notably changes in firing rates and muscle fiber atrophy, play in the manifestation of muscle weakeness. This role is compared with the lesser role that spasticity of the antagonist muscle group appears to play in determining the weakness of agonist muscles. The contribution of other factors that result in mechanical restraint of the agonist by the antagonist is discussed relative to muscle weakness in patients with hemiparesis. More studies on patients with hemiparesis are required to assess what role muscle strength training should play in rehabiliting patients after a stroke.

Safety performance of a new car is evaluated through USNCAP and their results in the star rating are provided to the consumers. It is very important to obtain high score of USNCAP to appeal their performance to consumers. Therefore the car companies have made the effort to improve their car safety performance. These efforts should satisfy the demand not only to get high score but also to pass the FMVSS, NHTSA regulations on safety. Huge numbers of car crash tests have been conducted on these bases by car companies. However physical tests spend too much cost and time, as an alternative way, the simulation on the car crash could be a solution to reduce the cost and time. Therefore the simulations have been widely conducted in car industry and various researches on this have been reported. In this study, restraint system had been optimized to minimize the injury of female passenger. Belted $5^{th}%ile$ female frontal crash test was selected from various test methods of USNCAP for the study. Initial velocity of the test was 56km/h. The combination injury probability of USNCAP was selected as an objective function and the injury limit value, which was defined in FMVSS, was set to an optimization constraint. Many researches that were similar to this study had been conducted, however most of them had limitation that interaction between airbag and safety belt had not been considered. Contrary to these researches, the interaction was considered in this study.

Buckling Restrained Braces can not only express the strength considered at the time of design, but also reduce the seismic load by energy dissipation according to the plastic behavior after yield deformation of the steel core. The physical characteristics and damping effect may be different according to the buckling prevention method of the steel core by the lateral restraint element. Accordingly, in this study, To compare hysteresis characteristics, Specimen(BRB-C) filled with mortar, specimen(BRB-R) combined with a buckling restraint ring and Specimen(BRB-EP) filled with engineering plastics was fabricated, and a cyclic loading test was performed. As a result of the cyclic loading test, the maximum compressive strength, cumulative energy dissipation and ductility of each test specimen was similar. But in case of the cumulative energy dissipation and ductility, BRB-C filled with the mortar specimen showed the lowest. This is considered to be because the gap between the steel core and the reinforcing material for plastic deformation was not uniformly formed by pouring mortar around the core part.

The purpose of this study was to investigate the effect of Modified Constraint-Induced Therapy (MCIT) on the effected upper extremity of children with hemiparesis. Four children with hemiparetic upper extremity caused by brain injuries were trained by MCIT for ten weeks. During the same period, all of the subjects were also involved in thirty-minute regular physical therapy and occupational therapy. During the treatment period, the unaffected upper extremities of the subjects were restrained by a specially designed hand splint or a mitten for five hours a day, five days per week. For two hours out of the five-hour restraint period, the affected upper extremities were intensively trained by performing various functional tasks, which were individually structured to emphasize use of the affected arm. A single-subject design with A-B-A reversal was employed in this study. The affected limb motor ability was evaluated by Melbourne Assessment, measuring the time to grasp and release nine pegs, and measuring grasping power. As a consequence of this study, the affected limb motor test scores of all four subjects in the baseline period were improved during the treatment period. Furthermore, the treatment effect was maintained during a one-month follow-up period. The results of this study support the assumption that MCIT is an effective therapeutic method to improve the sensory and motor abilities of hemiparetic children. It also increases the frequency of functional use of the hemiparetic hands of brain-injured children. Based on the results of this study, it can also be assumed that the modified CIT method is especially beneficial to these children by reducing the negative emotional effects of forceful restraint of the unaffected upper extremity. To optimize the functional recovery of the paretic upper extremity by CIT, the restriction period per day should be decided individually, according to the characteristics of the individual.

The purpose of this study is to understand the Physical characteristics of cement mortar about humidity control on indoors and wall crack restraint. Experiments were conducted on the strength, water absorption coefficient, drying-shrinking crack, length change, cracks of mortar plaster bases according to mixture rate by mixing cellulose fiber and diatomite into cement mortar. The excellent tensile & bending reinforcement efficiency of cellulose fiber and void filling ability of diatomite proved to be suppressing cracks of cement. And diatomite seems to improve moisture-protection efficiency of cement mortar because of its high water absorption ratio and slow drying speed.
