Column foot in traditional Chinese timber structures may be subjected to be uplifted due to the lateral load and subsequently reset under the vertical loads. The residual moment of the rocking column foot is the most important parameter representing the mechanical behaviors of column foot, and the simplification of joints is the basis of structural analysis of whole structure. The complicated mechanical behaviors of joint and the modeling of the column foot joint has been undertaken historically based on the experiments and numerical simulation. On the condition of limited application range of those models, a lack of simplified model to represent the mechanical behaviors of joint deserves attentions. There is a great need to undertake theoretical studies to derive the residual moment and make better simplified model of the joint. This paper proposes the residual moment and equivalent simplified model of the rotational stiffness for column foot joint. And, the timber frame is established based on the simplified model, which is verified by solid finite element model. Results show that a mutual agreement on the mechanical behaviors of the timber frame is obtained between the simplified model and the solid finite element model. This study can serve as the references of the structural analysis for the traditional timber structures.

More and more non-injured operations are being implemented these days, thanks to the development of medical technology. Still, however, most operations leave direct scars on patient' bodies, as well as accompanying pain. The massage as an independent nursing intervention can stimulate the circulation of the blood of tissue and muscle and increase the relationship between a patient and a nurse. The purpose of this study is to investigate the effect of foot massage on pain in post abdominal operative patients. The nonequivalent control group, pre-post test design is used for this study. From July 7, 2000 to February 20, 2001, the 40 patients who were operated under general anesthesia in a university hospital in Seoul were studied. They were divided into two groups ; 20 patients were part of the experimental group, and the others, in the control group. In order to evaluate the effect of foot massage, severity of pain was checked with the VAS (Visual Analog Scale) and also each patients' vital signs were measured with pulse rate, systolic blood pressure and diastolic blood pressure. The collected datas were processed by SAS version 6.12 program and analyzed by the Chi-square, Fisher's exact test, t-test and repeated measures ANOVA. The results of this study were as follows. 1. The severity of pain decreased significantly in the experimental group as compared to the control group following foot massage (t=-3.317, p= .002). 2. Measured vital signs in the experimental group had more reduction of that than in the control group following foot massage. - The pulse rate in the experimental group was lower than that in the control group following foot massage (F=7.73, p=.008). - The systolic blood pressure in the experimental group was lower than that in the control group following foot massage (F=25.75, p=.000). - The diastolic blood pressure in the experimental group was lower than that in the control group following foot massage (F=15.27, p=.000). In conclusion, foot massage is an effective dependent nursing intervention for pain control of post abdominal operative patients.

Objective: Persons with stroke have a tendency to exhibit asymmetric weight-bearing during sit-to-stand because due to the attempt to support themselves with the non-paretic foot. However, there are few devices that can assist with sit-to-stand (STS) performance. This study was designed to investigate the use of the elastic band with rings (EBR) in improving weight-bearing effectively in persons with stroke during STS training. Design: Cross-sectional study. Methods: Thirteen stroke survivors participated in the study. An EBR was applied onto the patient during STS activity. The foot pressure was measured before and after wearing the EBR, with a 5-minute rest period between measurements. Subjects were asked to perform each test twice with and without the EBR. Bilateral feet pressures were measured with standing posture being divided into the forward and backward aspects. The foot contact pressure during STS activity was measured with the CONFORMat System. Results: With EBR, the forward pressure of the affected foot significantly increased while the less-affected forward foot pressure significantly decreased (p=0.015 and p=0.023, respectively). The backward foot pressure did not differ significantly in the two limbs, and there was no difference with and without the EBR in terms of the total pressure of the affected foot. There was a significant difference with and without the EBR in the total pressure of the less-affected foot (p<0.05). Conclusions: STS training with the EBR has been shown to improve weight-bearing of both feet while decreasing the total pressure of the less-affected foot in stroke survivors. Therefore, we suggest that the EBR is a useful tool for STS training for persons with stroke in the clinic.

In this study, new design method of prosthetic foot was suggested which can evaluate the performance of prosthetic foot by implementing amputee's gait simulation using the finite element analysis. The basic shape of ESPF(Energy Storing Prosthetic Foot) was designed which is suitable for the below-knee amputee considering mechanical properties and kinematic properties. And, the performance evaluations were performed using the Taguchi method with orthogonal array L25. As a result, average main effect of factors for the ESPF's performance were calculated and then optimum condition of given shape was selected. Essential particulars for the performance evaluation from the simulation result were the quantity of external work needed in stance phase, the quantity of transferred energy from the ESPF through the knee, and the vertical displacement of knee at toe-off. Reasonable optimum condition was obtained from the using performance index. From this study, it was found that it is necessary for the design of ESPF to consider the geometrical data related to the magnitude of load on elastic material.

Modern people are suffering from a lack of exercise along with their daily lives, and the foot's pedigree disease is increasing as a result, foot pedigree disease is also increasing. As a result, the design of socks is diversifying, and among them, the development of toe socks that help prevent and alleviate foot problems is also actively underway. Thus, this study conducted a study on toe socks design and summarized the concept of toe socks design through theoretical background. It also established tasks to be used for usability evaluation through case studies and prior research. An empirical study showed that the satisfaction of toe socks design was lower than that of ordinary socks, and that of toe socks design was more satisfactory in terms of usability. As a result, improvements in toe sock design have been derived, and it is expected that the hidden partitions between first toe sock can be supplemented, and toe sock design can be improved through similar color scheme and color diversification.

For commercial vehicles with a manual transmission, the pneumatic and fluid pressure servo-device is widely used for transmitting large torque. However, the pneumatic and fluid pressure servo-device usually results in non-linear variation of foot-efforts, also such characteristics tend to increase physical fatigue of drivers who drive commercial vehicles for a long time. Thus, vehicle manufacturers consider the hysteresis loops in the Clutch Actuation System (CAS) design when a new vehicle model is being developed. In this study, we numerically simulate the hysteresis loops for predictable CAS design, and the experimental results confirm the simulation results.
