퇴행성 변화를 겪으면서 발생할 수 있는 각종 신체 질환을 포함한, 재활환자들의 보행검사 평가 지표는 환자별 텍스트 형식으로 입력되어 있는 자료들로부터 평가 지표를 얻는다. 본 연구에서는 시간적 정확도 향상을 위하여 환자 개인과 특정 질환 집단의 측정 데이터를 개인, 집단 형식으로 차트 형식으로 시각화함으로써 연구 시 오차 범위를 줄이고, 자료 분석 시간을 감소시켜 효율성을 증대 시키고자 하였다. 또한, 추후 각 분야의 전문의와 협력해 환자 측정 데이터에 따라 의심 질환 제시까지 가능한 의료콘텐츠 소프트웨어로서 개발 가능하도록 하였다. In this study, we introduce a new way to improve the efficiency of Gait Analysis and promote its usage. This program can be shown in different points of view such as an individual or group patient data. The Gate Data Visualization Program is improving its efficiency by minimizing the margin of error during research and promoting the easy interpretation. In addition, this program is designed to have an easy access, and can be used to develop the most basic medical equipment program to predict a probable disease for patient by collaborating with physicians specializing in neurosurgery.

본 연구는 ENACT 모형을 지구과학 교과 수업에 적용하여 과학기술자의 사회적 책임에 대한 과학영재 학생의 인식 변화를 알아보고, 학생들의 학습 만족도를 알아보고자 하였다. ENACT 모형 적용 학습을 위한 주제는 2015 과학과 개정 교육과정과 연계하여 과학기술 발전에 따른 사회 쟁점 주제를 선정하였다. 또한, 선정된 주제와 관련 있는 실제 야외 현장의 일부를 가상현실(PVR) 콘텐츠로 제작하여 ENACT 모형 적용 수업에 활용하였다. D광역시 과학영재 고등학교 1학년 60명의 학생을 대상으로 ENACT 모형 적용 수업 전과 후 과학기술자의 사회적 책임에 대한 인식 사전ㆍ사후 검사를 각각 수행하였고, 적용 수업 후 학습 만족도 검사를 수행하였다. 사전ㆍ사후 대응 표본 t-검정 결과 ENACT 모형 적용 지구과학 교과 수업은 과학기술자가 갖추어야 할 사회적 책임에 대한 과학영재 학생의 인식 변화에 통계적으로 긍정적 영향이 있음을 확인하였다(p<.05). 또한, 학생들의 학습 만족도 분석 결과 수업 목표 달성 영역에서 사회 쟁점(SSI)에 대한 관심도 측면, 비판적 시각 측면, 바람직한 미래 상황 예측의 필요성 측면, 문제해결을 위한 이해관계자와의 의사소통 능력의 필요성 측면에서 긍정적인 학습 만족도(전체 평균 6.24)를 보였다. 아울러, 사회적 실천 단계로의 태도 함양 측면에서 긍정적 학습 만족도(전체 평균 5.93)를 보였다. 이를 통해 ENACT 모형 적용 수업은 미래사회를 이끌어갈 과학영재 학생들에게 과학기술자가 갖추어야 할 사회적 책임의 중요성 인식과 사회 쟁점(SSI)을 해결하기 위한 실천적 태도 함양에 기여할 수 있음을 시사한다. This study applied the ENACT model to earth science classes to find out the change in science-gifted students' perception of the social responsibility of scientists and engineers, and to find out the students' learning satisfaction. For 60 1stgrade students at a science-gifted high school in D Metropolitan City, before and after classes to which the ENACT model was applied, pre- and post-tests for awareness of science and technology engineers' social responsibilities were conducted, and a learning satisfaction test was conducted after the classes to which the ENACT model was applied. The results of the pre-and post-paired sample t-test confirmed that the ENACT model-applied earth science subject class had a statistically positive effect on the change in science gifted students' perception of the social responsibility that scientists and engineers should have (p<.05). In addition, the results of students' learning satisfaction analysis, the aspect of interest in socio-scientific issues(SSI) in the area of achieving class goals, the aspect of critical perspective, the aspect of the need to predict desirable future situations, the aspect of the need for communication skills with stakeholders to solve problems showed positive learning satisfaction(overall average 6.24). This suggests that ENACT model applied classes can contribute to the perception of the importance of social responsibility that science engineers must have and the cultivation of practical attitudes to socio-scientific issues(SSI) for science gifted students who will lead the future society.

The insulator being used for transmission line is to mount the charged conductor on the tower or other supports. The insulators are classified according to its material: porcelain, glass and polymer. Polymer insulators are also called as composite insulator or non ceramic insulator (NCI). Insulators are a major element of a power transmission system. Since a faulty insulator can lead to a wide spreading blackout, it must have sufficient mechanical and electrical strength. It must be durable, have high electrical insulation and be able to withstand a leakage current. It must also be able to withstand the toughest weather conditions. In Korea, porcelain insulators have been used widely. However, to make compact equipment and keep up with global trends, we have enhanced domestic production of polymer insulator and are encouraging its applications. Accordingly, this thesis will look at types of insulators, use and trends, and prospects of insulators application in the field.

Objective: The aim of this study is to incorporate appropriate ergonomic evaluation factors to reduce the physical load that can be imposed on the way of usability evaluation procedure. Background: It has been required to prove that the usability aspect of the product is considered in the product development process for approval of the medical device approval. Accordingly, the usability evaluation report performed during the product development process is required. However, musculoskeletal diseases caused by the use of medical devices are occurring to medical staffs who use the developed product to evaluate the usability test. It is considered that the human factors such as the physical load that can be applied to the user in the process of considering the usability of the user are not sufficiently, actually there is no evaluation method that requires checking the degree of physical load. Method: To compare the amount of physical load that can be applied to the user, the evaluation was carried out according to four procedures. First, prototype designs were selected for the evaluation process, Next, the evaluation items for the evaluation of the degree of physical load were developed, and the intended users were recruited and performed usability evaluation. Finally, the results of the survey were analyzed and some improvements were made. Results: Analysis of the evaluation data showed that it was possible to select the most useful design among the prototype designs that were evaluated, We could derive the improvement direction through the evaluation results of other designs about the items with relatively low satisfaction score among the evaluation item of the selected design. In addition, experienced experts in development equipment have been able to develop the final model considering the requirements of the actual clinical environment. Conclusion: Through this study, it was confirmed that the improvement requirements which can be considered the user’s physical load degree are derived.
