Recent reports have described several cases of double muscle transfers to restore natural, symmetrical smiles in patients with long-standing facial paralysis. However, these complex procedures sometimes result in cheek bulkiness owing to the double muscle transfer. We present the case of a 67-year-old woman with long-standing facial paralysis, who underwent two-stage facial reanimation using two superficial subslips of the serratus anterior muscle innervated by the masseteric and contralateral facial nerves via a sural nerve graft. Each muscle subslip was transferred to the upper lip and oral commissures, which were oriented in different directions. Furthermore, a horizontal fascia lata graft was added at the lower lip to prevent deformities such as lower lip elongation and deviation. Voluntary contraction was noted at roughly 4 months, and a spontaneous smile without biting was noted 8 months postoperatively. At 18 months after surgery, the patient demonstrated a spontaneous symmetrical smile with adequate excursion of the lower lip, upper lip, and oral commissure, without cheek bulkiness. Dual-innervated muscle transfer using two multivector superficial subslips of the serratus anterior muscle may be a good option for long-standing facial paralysis, as it can achieve a symmetrical smile that can be performed voluntarily and spontaneously.

사회보장법에 나타나는 위임의 정도는 의회의원후보공천방식과 의회상임위원회제도의 운영방식과 관련이 있다. 위임이 적은 사회보장법 구조는 상향식 공천방식과 지속적으로 임기를 보장하는 상임위원회제도와 친화적이다. 독일과 같이 당원이 연방의원후보를 결정하는 과정에서 중요한 역할을 하는 상향식 공천방식과 지속적인 임기를 보장하는 상임위원회제도는 위임이 적은 독일의 사회법과 친화성을 갖는다. 반면에 위임이 많은 사회보장법 구조는 하향식 공천방식과 지속적인 임기를 보장하지 않는 상임위원회제도와 친화적이다. 우리나라와 같이 국회의원후보자를 중앙당에서 주도적으로 결정하는 하향식 공천방식과 지속적인 임기를 보장하지 않는 상임위원회제도는 위임이 많은 우리나라의 사회보장법과 친화성을 갖는다.

In patient of long standing malunited maxillary fracture, maxillary osteotomy or refracture seems to be justifiable. This is a case of the patient, a 60 year old Korean female patient, presented a long-standing malunited maxillary fracture with dish-type face and functional disturbance in mouth opening. We performed upon her Le Fort I osteotomy only via labial-buccal horizontal incisions in one-stag operation. The result was good in esthetics and function.

Objective: This study analyzed the correlation between uni-standing balance ability, jumping ability, and anaerobic lower extremity power of high school Taekwondo players. Design: Cross-sectional study Methods: Two high schools recruited 36 taekwondo players, but 5 were dropped due to personal circumstances and preparations for the tournament, so the number was counted as 31. In order to test uni-standing balance ability, the Romberg test was performed using Biorescue to measure the sway area. In order to test jumping ability, standing long jump and standing highjump were measured. For anaerobic lower extremity muscle power test, the peak power and average power were measured through 30-second pedaling using a Wingate system bicycle. Results: Participants did not show any correlation with other measures in the uni-standing balance ability test (p>0.05). Looking at the correlation in the standing long jump, standing high jump (r=0.892, p<0.05), anaerobic peak power (r=0.698, p<0.05), anaerobic average leg power (r=0.662, p<0.05) showed a positive correlation. Looking at the correlations in the standing high jump, anaerobic peak power (r=0.663, p<0.05), anaerobic average power (r=0.697, p<0.05) showed a positive correlation. Looking at the correlation in the anaerobic peak power, average power (r=0.785, p<0.05) showed a positive correlation. Conclusions: This study shows that balance ability and anaerobic leg strength are independent of each other. The results of this study can be used as basic data for the training plan of high school taekwondo players in the future.

The Work-Related Musculoskeletal Disorders (WMSDs) can be occurred by various factors such as repetition, forceful exertions and awkward postures. Especially, occurrences of the WMSDs on the waist and lower limb are reported in workplaces, demanded standing postures for a long time, in service and manufacturing industry. The static and standing postures without movement for a long time increase work loads to the lower limb and the waist. Accordingly, anti-fatigue mat or anti-fatigue insole is used as a preventing device of the WMSDs. However anti-fatigue mats are limited in space and movement. In this study, multi-elastic insoles are designed and shown the effects of the workload reduction for a long time under the standing work. The foot pressures and EMG (Electromyography) are measured at 0 hour and after 2 hours by 6 health students in their twenties. The 6 prototype insoles are designed with three elastic (Low, Medium and High). These insoles are compared with no insole (insole type 7) as control group. The EMG measurement was conducted to waist (erector spinae muscle), thigh (vastus lateralis muscle) and calf (gastrocnemius muscle). The foot pressure is analyzed by mean pressure value and the EMG analysis is investigated through MF (Median Frequency), MPF (Mean Power Frequency) and ZCR (Zero Crossing Rate). The results of the foot pressure show that the multi-elastic insoles had smaller foot pressure value than that of no-insole. Moreover, Insole 2 and Insole 3 have the smallest increasing rate in foot pressure. The EMG results show that the multi-elastic insoles had smaller EMG shift value than that of no-insole in 2 hour, and then shift value shows the smallest value in Insole 2. Therefore, this study presents that the multi-elastic insoles have reducing effects of the work load for a long time standing work in both side of foot pressure and EMG.

This study starts from the awareness of the problem that consumers are isolated from the standing spray product planning, and thus suggests effective designs and methods to the new standing spray design process. The ultimate purpose of this study is to suggest practicable new standing spray design outputs. Service design is based on customer experience, and thus it is intangible, process-centered and based on various relations. Applying the service design to the development of new standing spray designs has the following significance. (1) Service design is an effective method for maximizing customer-centered experience. The customer-centered method of service design promotes practicability of new standing spray design. (2) Service design solves various problems by mediating opinions among various stakeholders. Effective and practicable solutions could not be found for new standing spray design despite various efforts that had been made for a long time. Since each step of the process is approached separately, it is necessary to take an overview of the whole process like service design. (3) Service design lays stress on process in which stakeholders participate. Participation and collaboration among stakeholders in the new standing spray design process will improve their satisfaction and enthusiasm to implement the new system.

Purpose: The aim of this research was to verify the relationship between three-dimensional (3D) ground reaction force (GRF) and severity of leg length discrepancy (LLD) while walking at a normal speed. It used a 3D motion analysis system with force platforms in standing workers with LLD. Methods: Subjects comprising 45 standing workers with LLD were selected. Two force platforms were used to acquire 3D GRF data based on a motion analysis system during gait. Vicon Nexus and Visual3D v6 Professional software were used to analyze kinetic GRF data. The subjects were asked to walk on a walkway with 40 infrared reflective markers attached to their lower extremities to collect 3D GRF data. Results: The results indicated the maximal force in the posterior and lateral direction of the long limb occurring in the early stance phase during gait had significant positive correlation with LLD severity (r = 0.664~0.738, p <0.01). In addition, the maximal force medial direction of the long limb occurring in the late stance phase showed a highly positive correlation with the LLD measurement (r = 0.527, p <0.01). Conclusion: Our results indicate that greater measured LLD severity results in more plantar pressure occurring in the foot area during heel contact to loading response of the stance phase and the stance push-off period during gait.

This paper presents a seismic analysis method that can evaluate a very large number of cases for the free standing dry storage cask by proposing a methodology that has short analysis time as well as accuracy. This study also performed a seismic analysis of a dry storage facility with multiple casks to show a tip-over phenomenon from earthquake accident conditions. The earthquake accident condition is long-term event that occur during about 20 s long, and lots of seismic analysis cases should be performed to consider various real conditions because the free-standing spent-fuel dry storage cask has many nonlinear responses. The soil-concrete pad-cask interaction was considered in the seismic analysis and finite element model was made using concrete pad, soil and cask models. In the reinforced concrete pad, the rebar was excluded to reduce the analysis time, but the thickness was corrected to maintain the bending rigidity. Additionally, the analysis time reduced by modeling the cask as a rigid body rather than a flexible body. 35-cases of seismic analysis were performed to determine a tip-over phenomenon from each earthquake. The analysis revealed that no tip-over phenomenon of the cask was observed in all analyses from 0.2 g to 0.6 g, however the tip-over of the cask were observed from 0.8 g with friction coefficients of 0.8 and 1.0.
