This study identified the difference in the effect of free learning semester on career maturity by grade to analyze the effectiveness of free learning semester in middle school. The analysis targets 417 students in the first, second and third grades of nine middle schools in Jeonbuk Province. According to the analysis, the satisfaction level of free learning semester was above average, and career maturity level was high. Looking at the differences by grade, the satisfaction level of free learning semester was statistically significantly higher in the first and second grades than in the third grades. Also, career maturity was in the order of second grade, first grade, and third grade, and especially second grade was statistically significantly higher than third grade. For each grade, the correlation between satisfaction with free learning semester and career proficiency was high in the first grade (r= 6.6 or higher), while the third grade (r=.3 to 4) showed a low static correlation. However, the second grade had no correlation. The effect of the satisfaction of free learning semester on the components of career maturity by grade on the basis of the satisfaction of free learning semester for the first and third graders affected all the components of career maturity. Satisfaction with free learning semester of the first grade showed 30 to 40 percent of the explanation on the components of career maturity. However, the third-year student had only about 10 percent of the explanation. Satisfaction with free learning semester did not affect career maturity in second grade. Proposals based on the findings are as follows. First, the school year-by-year approach should be applied to middle school career education that covers free learning semester. Second, it is necessary to explore various variables and school conditions to enhance the effectiveness of free learning semester.

Objectives This study explored the mediating effect of school life adaptation in the effect of free semester system satisfaction by grade on career maturity attitude in order to draw policy implications for career development of middle school students by exploring the linkage effect of free semester system in middle school. Methods To this end, data were collected through a survey on the satisfaction of free semester system, career maturity attitude, and school life adaptation variables for 417 students in 9 middle schools in Jeonbuk-do Province, and the results were analyzed by SPSS 24.0 program. Results As a result of the analysis, free-semester satisfaction decreased as grades increased, but career maturity attitude and adaptation to school life were in the order of 2nd, 1st, and 3rd grade. In 1st and 3rd graders, free-semester satisfaction had a direct effect on career maturity attitude and adaptation to school life, respectively. In addition, free-semester satisfaction and adaptation to school life had an effect on career maturity attitude, and the mediating effect of adaptation to school life was also verified in the relationship between free-semester satisfaction and career maturity attitude. However, in the second grade, free-semester satisfaction had no effect on career maturity attitude and adaptation to school life, and only adaptation to school life had an effect on career maturity attitude. Also, there was no mediating effect of adaptation to school life between free-semester satisfaction and career maturity attitude. Conclusions The conclusions based on the research results are as follows. First, it is necessary to reconsider unit schools, community networks, and government-wide cooperation systems to increase satisfaction with the free semester system. Second, it is necessary to apply a grade-level approach to career education. Third, it is necessary to support adaptation to school life so that middle school students can cultivate career development. 목적 이 연구는 중학교 자유학기제의 연계효과를 탐색하여 중학생의 진로발달을 위한 정책적 시사점을 도출하기 위해 학년별 자유학기제 만족이 진로성숙 태도에 미치는 영향에서 학교생활적응의 매개효과를 탐색하였다. 방법 이를 위해 전라북도 9개 중학교 학생 417명을 대상으로 자유학기제 만족, 진로성숙태도, 학교생활적응변인에 대한 설문조사를 통해 자료를 수집하여 SPSS 24.0 프로그램으로 결과를 분석하였다. 결과 분석결과 자유학기제 만족은 학년이 높아지면서 낮아졌지만 진로성숙 태도와 학교생활적응은 2학년, 1학년, 3학년 순이었다. 1학년과 3학년은 자유학기제 만족이 진로성숙 태도와 학교생활적응 각각에 직접적인 영향을 미쳤다. 또한 자유학기제 만족과 학교생활적응이 진로성숙 태도에도 영향을 미쳤고, 자유학기제 만족과 진로성숙 태도의 관계에서 학교생활적응의 매개효과도 검증되었다. 그러나 2학년은 자유학기제 만족이 진로성숙 태도와 학교생활적응 각각 영향이 없었고, 학교생활적응만 진로성숙 태도에 영향을 미쳤다. 또한 자유학기제 만족과 진로성숙 태도 사이의 학교생활적응의 매개효과도 없었다. 결론 연구결과에 따른 결론은 다음과 같다. 첫째, 자유학기제 만족을 높이기 위한 단위학교, 지역사회 네트워크, 범정부적 협력체계에 대한 재고가 필요하다. 둘째, 진로교육에 대해 학년별 접근법을 적용할 필요가 있다. 셋째, 중학생의 진로발달을 함양할 수 있도록학교생활적응을 지원하여야 한다.

임베디드 보드에서 차량 감지 및 추적을 위한 딥러닝 모델 최적화

황연우,조성원 한국지능시스템학회 2022 한국지능시스템학회논문지 Vol.32 No.2

This paper proposes a deep learning model to detect and track the vehicle on an embedded device. Since deep learning has achieved high accuracy over the classical image processing method, object detectors can detect vehicles in the street and highway. It can be normal to run the computer detection program with graphic processor unit (GPU) support, but it is challenging to run it on the embedded board with no GPU support and low central processing unit (CPU) performance. This paper focuses on balancing edge-computing-based deep learning object detection's accuracy and performance using additional techniques such as quantization, edge TPU. SSDLite with MobileNet backbone is chosen due to its lighter than other networks but still obtain good performance compare with Yolo. The model was learned with DeepSORT using SSDMobileNetV2 as an object detector so that the vehicle could be tracked. This paper evaluates the performance of deep learning model to detect and track the vehicle through the developed board using H6 CPU. 본 논문은 임베디드 보드에서 차량을 감지하고 추적하기 위한 딥러닝 모델을 제안한다. 딥러닝이 기존 이미지 처리 방법에서 높은 정확도를 보여주고 있기 때문에 기존 객체 검출기로 거리나 교량에서 차량을 감지할 수 있다. 그러나, 범용 PC를 사용하는 경우 GPU를 사용하여 프로그램을 실시간으로 동작하는 것이 가능하지만, 임베디드 보드에서는 GPU를 사용하기 어렵고 낮은 성능의 CPU를 사용하므로 프로그램의 실시간 처리가 불가능하다. 본 논문에서는 양자화, edge TPU와 같은 방법을 이용해서 에지 컴퓨팅 기반 딥러닝을 이용한 객체 감지의 정확도와 성능 향상을 시도하였다. Yolo와 같은 다른 네트워크보다 MobileNet을기반한 SSDLite가 빠른 추론시간과 높은 정확도를 보여줘 선정했다. SSDMobileNetV2를 객체 감지기로 사용한 DeepSORT로 모델을 학습하여 차량을 추적할 수 있도록 하였다. 본 논문에서는 H6 CPU를 이용하여 자체 제작한 보드를 통해 차량 감지 및 추적을 위한 딥러닝모델의 성능을 확인하였다
