이 연구는 내수면 수난 구조상황에서의 급상승이 코르티솔 및 인체 증상에 미치는 영향을 분석한 것으로 실험 결과는 다음과 같다. 실험대상자는 5명으로 A, B, C는 잠수 전후 코르티솔 상승 수치가 각각 6.30ug/dl, 6.50ug/dl, 6.57ug/dl로 비슷한 수치를 나타내었다. 그런데, 실험대상자 D는 잠수 전후 코르티솔 상승 수치가 11.00ug/dl로 유의하게 높게 나타났다. 그 이유는 수중 시계의 불량으로 인한 불안감 가중 및 급상승 시 긴장을 통한 체력소모 고갈로 판단된다. 실험대상자 E는 잠수 전후 코르티솔 상승 수치가 4.28ug/dl로 유의하게 낮게 나타났는데, 그 이유는 E의 연령이 실험대상자 중 가장 젊고, 해상의 심해 잠수 경험이 풍부하여 불안감이 작아서 나타난 결과로 보인다. 피로도는 7~8, 불안감은 7~9로 둘 다 높은 수치를 나타내었다. 수중수색 시 심리적 긴장감이 피로도를 높이고, 불량한 시계가 불안감을 높인 것으로 사료 된다. 연구 결과는 수난구조대원의 안전한 수중수색 활동에 대한 실증적 자료로 제공될 것이다.

이 연구는 내수면의 수난사고 중에서도 수중수색 부분에 한정하고, 수중 5m에서 5가지 수중탐색 방법과 인명구조 시간을 분석하였다. 실험대상자는 10명으로. 반원 탐색은 259초로 가장 길었고, 변형된 왕복 탐색 방법은 78.60초로, 평균 180.04초의 유의미한 차이를 보였다. 실험대상자 B, D는 수중탐색 평균 시간이 각각, 199초, 202초로 비슷한 수치를 나타내었다. 실험대상자 C는 수중탐색 평균 시간이 209초로 유의하게 높게 나타났다. 그 이유는 수중 시계의 불량으로 인한 불안감 가중 및 과도한 긴장에서 기인한 것으로 보인다. 실험대상자 A는 수중수색 시간이 187초로 유의하게 낮게 나타났다. 그 이유는 E의 경력이 실험대상자 중 가장 많고, 시계가 불량한 한강에서의 잠수 경험이 풍부하여 나타난 결과로 보인다. 편리성은 반원 탐색은 6~7로 낮게, 변형된 왕복 탐색이 8~9로 높은 수치를 나타내었다. 시계가 불량한 한강에서의 수중탐색 방법으로 가장 적합한 구조 방법은 변형된 왕복 탐색 방법으로 판단된다.

PURPOSE: Stroke patients have reduced balance ability due to a lack of motion in the ankle joint. Elastic taping assists movement, and joint mobilization, a form of passive movement, enhances mobility. The purpose of this study was to determine the immediate effects on balance ability after anterior-to-posterior (A-P) talocrural joint mobilization combined with elastic taping in stroke patients. METHODS: Twenty stroke patients were divided into two groups: a joint mobilization with taping group (experimental group, n=10) and an elastic taping only group (control group, n=10). The experimental group underwent anteroposterior mobilization of the talus and elastic tape was applied to the calf and tibialis anterior muscles. The control group had elastic tape applied. Dynamic balanced abilities were assessed by using the BioRescue system. After 30 minutes of intervention, the forward, backward, left side, and right side sway areas ($mm^2$) were measured. RESULTS: Only the experimental group showed a significant increase in forward sway area after intervention. However, no significant differences were detected between the two groups. CONCLUSION: This study shows that A-P talocrural joint mobilization combined with elastic taping has a positive effect, producing an immediate increase in the forward balance ability of stroke patients. However, this study did not examine joint mobilization alone. In subsequent studies, it is necessary to examine the effect of joint mobilization only on balance in stroke patients.

Purpose: This study was dont: to evaluate the factors that influence secondary traumatic stress, burnout, and physical symptoms experienced by firefighters. In addition, a hypothetical model was developed. Method: The data were collected using self-reported questionnaires from 410 field service firefighters. Data analysis was done with the SPSSWIN 10.0 program for descriptive statistics and Windows LISREL program to determine the causal relationship between the measurement variables. Results: The hypothetical model which was developed fits well with actual data(${\chi}^2$=3.16, p=0.99, GFI=1.00, AGFI=0.99, NFI=0.99, and NNFI=1.06). The variable, personality type, social support, and impact mobilization frequency had a significant effect and accounted for 7% of the secondary traumatic stress in firefighters. The variables, career, social support, and secondary traumatic stress had a significant effect and accounted for 24% of the burnout in firefighters. Social support, impact mobilization frequency, and secondary traumatic stress were important variables and accounted for 31% of the physical symptoms in firefighters. Conclusion: It is necessary for firefighters to manage themselves according to their personality types. Strategies that can increase the firefighters' social support and decrease their perceived secondary traumatic stress also need to be developed to minimize or prevent a negative effect on their health.

Background: A number of researchers have attempted to improve the balance of stroke patients, however there is still a question as to whether taping is effective in increasing balance. Objective: To determine the effect of paretic and non-paretic side taping on the balance ability in patients with stroke. Design: A single-blind randomized controlled trial Methods: This randomized single-blind controlled clinical trial with a repeated measures study included 45 subjects who were randomly assigned to paretic side taping groups (n=15), non-paretic side taping groups (n=15), and trunk exercise groups (n=15). Trunk exercise and paretic side taping groups had taping on the paralyzed erector spinae, while the non-paretic side taping group had taping on the non-paralyzed erector spinae. Trunk exercises were performed for 30 minutes to promote core muscles. The balance ability measured the center of pressure movement (paretic side, non-paretic side,forward, backward, limit of stability) in the sitting position. All measurements were evaluated using BioRescue. Results: All three groups showed significant increase in all variables after 4 weeks. The paretic and non-paretic side taping groups had a significant increase in all variables after 30 min of attachment. However, there was no significant difference among the three groups. Conclusions: Paralysis and non-paralysis taping improved the balance ability of patients with stroke in an immediate effect of 30 min. However, after 4 weeks of intervention, taping with trunk exercise did not differ from single trunk exercise. In future studies, various analyses need to be conducted through more diverse evaluations.

This paper deals with the development and application of control algorithms for series elastic relief robots for rescue operations in harsh environment like disasters or battlefield. The joint controller applied in this paper has a cascade structure combining inner loop for torque control and outer loop for position control. The torque loop contains feedforward and feedback controller and disturbance observer for independent, decentralized joint control. The effect of the elastic component and motor dynamics are treated as the nonlinear disturbance and compensated with the disturbance observer of torque controller. For the collision detection, Band Designed Disturbance Observer is configured to recognize/respond to external disturbance robustly in the continuously changing environment. The controller is applied to a 7-dof series elastic manipulator to evaluate the torque tracking and collision detection/response performance.

본 연구는 복식호흡을 병행한 척추 안정화 운동이 요통환자의 균형능력과 통증에 미치는 영향을 알아보기 위해 시행되었다. 20대 요통환자 18명을 대상으로 하였으며 실험군은 척추안정화 운동을 실시하는 동안 복식호흡을 함께 적용하였으며 대조군은 척추안정화 운동만을 시행하였다. 운동은 8주간 적용하였으며 운동 시작 전과 후에 오스웨스트리 요통장애지수 설문지를 사용하여 통증을 비교하고 BioRescue를 사용하여 신체중심이 이동한 길이와 면적을 측정하여 균형능력을 비교하였다. 실험결과, 두 그룹 모두 운동 후, 요통장애지수가 유의하게 감소하였으나 그룹간의 유의한 차이는 없었다. 신체중심이동면적 비교에서 실험군은 운동 후 유의한 감소가 있었으나 그룹간의 유의한 차이는 없었다. 신체중심이동길이의 비교에서 눈을 감은 상태에서 실험군은 유의한 차이가 있었으나 대조군은 유의한 차이가 없었으며 그룹간 비교에서도 유의한 차이가 있었다. 이러한 결과를 통해 요통환자에게 안정화운동과 복식호흡을 함께 병행하여 실시한다면 더욱 효과적일 것이라고 생각된다.

With the rapid development of urban suburbanization, a plenty of commercial operation of suburban environmental resource, the environment in suburb is more and more deteriorated. It also leads some passive effect on ecology, human, society and nature etc. At the same time, a serial of emergency rescue action has been implemented to decrease the deteriorating of suburban environment. For example, some important ecology nature reserves were built up; some compulsive protections have been put in practice for some key resource development region and gotten some good achievements. However, we still face the problem is that how to balance the contradiction between suburban environment resource development and conservation. It's necessary to introduce some western advantage management ideas, combined our actual situation, to find a way which is the most benefited to combine our country's suburb environment development and use.

This study examines the effects of the public's perception of emergency medical service (EMS) on the public health system's brand equity and the moderating effect of governance on this relationship using Keller's customer-based brand equity model. It uses four EMS functions: rescue/first-aid and transfer activities; disaster prevention, preparation, and response activities; educational activities in urgent situations; and medical treatment in emergency rooms to examine the effects of them on brand meaning of the public health system. Our findings are important for understanding the public as customers of the public health system and devising and/ or adapting healthcare policies and marketing strategies to develop brand equity and increase customers' loyalty to the public health system.
