이 연구는 자동 차량위치 측정기법(Automatic Vehicle Location, AVL)을 이용해서 수집한 교통상황자료를 가지고 구간 통행시간을 산출하는 알고리즘을 개발한다. AVL기법을 이용하는 경우, 처리해야 할 자료량이 많아서 실시간에 정보를 산출하는 것이 힘들다. 따라서 이 연구는 처리해야 할 자료량을 가능한 한 줄이고 자료량이 적은 경우에도 효율적인 구간통행시간을 산출하는 알고리즘을 제시한다. 이 연구의 방법론은 크게 4가지인데, 첫째, 해석 기법, 둘째, 회귀분석, 셋째, 인공지능 및 전문가 시스템, 넷째, 통계분석이다. 이 방법론을 이용해서 세 단계 알고리즘을 개발하는데, 첫째는 실시간 분석통계 알고리즘, 둘째는 과거자료분석 알고리즘, 셋째는 자료응합 알고리즘이다. 이 알고리즘 가운데 자료융합 알고리즘 결과가 산출하고자 하는 구간 통행시간이다. 실시간 분석통계 알고리즘은 연속하는 세 개 구간의 통행 패턴을 이용해서 가운데 구간의 통행시간을 산출하는 방법을 제시한다. 또 실시간 분석통계 알고리즘으로 산출하지 못한 구간은 인접구간 상관도 정보를 이용해서 구간통행시간을 추정한다. 과거자료분석 알고리즘은 회귀분석을 이용해서 시간대별 통행시간 평균과 분산을 구하고, 이 결과를 바탕으로 인접구간 상관도 정보를 오프라인으로 구하는 알고리즘이다. 자료융합 알고리즘은 2가지 단계를 거치는데, 그것은 실시간 자료융합과 최종 자료융합이다. 실시간 자료융합은 실시간에 가까운 자료원의 실시간 분석통계 알고리즘 결과 패턴과 인접구간 상관도 정보를 이용한 구간통행시간 추정 결과를 이용해서 패턴에 따라 다른 방법으로 융합을 하는 알고리즘을 개발한다. 최종 자료융합은 실시간 자료융합 결과와 회귀분석 결과의 패턴을 이용해서 구간 통행시간을 산출한다. 이 연구를 기존 연구와 비교할 때, 세 가지 독차성이 있다. 첫째는 연속하는 세 구간 통행 패턴을 분석하였기 때문에 기존의 노드의존 방식을 탈피하였다는 점이다. 따라서 자료량이 적은 경우도 믿을만한 통행시간을 산출할 수 있다는 것이다. 둘째는 인접구간 상관도 정보를 구간통행시간 산출에 이용하였기 때문에 자료를 효율적으로 이용할 수 있다는 점이다. 셋째는 자료원 패턴을 분류하고 전문가 시스템을 이용하여 자료융합 하였기 때문에 수행속도가 빠르고, 신뢰성있는 정보를 제공한다는 점이다. 이 연구는 개발한 알고리즘 정확도를 검증하기 위해서 두 가지 검증방법을 이용하였다. 첫째는 시뮬레이션을 이용한 것이고, 둘째는 실제 주행조사 분석을 이용한 것이다. 두 가지 검증 결과는 알고리즘 정확도를 보여준다.

The purposes of this study were to investigate the value, necessity and legitimacy of STEAM Education and to propose practical approaching methods for STEAM Education to be applicable in Korea through a variety of literature review, case studies and collecting suggestions from domestic and international educational experts. The research questions are as follows: (1) To investigate the perception, understanding and recognitions of domestic and foreign professionals in STEAM education. (2) To analyze policy implications for an improvement in STEAM. The following aspects of STEAM were found to be challenges in our current STEAM policy after analyzing multiple questionnaires with the professionals and case studies including their experiences, understanding, supports and directions of the policy from the governments. The results indicate that (1) there was a lack of precise and conceptual understanding of STEAM in respect to experience. Training sessions for teachers in this field to help transform their perception is necessary. Development of practical programs with an easy access is also required. It is important to get the aims of related educational activities recognized by the professionals and established standards for an evaluation. The experts perceived that a theme-based learning is the most preferred and effective approaching method and the programs that develop creative thinking and learning applicable to practice are required to promote. (2) The results indicate that there was a lack of programs and inducements for supporting outstanding STEAM educators. It is shown that making an appropriate environment for STEAM education takes the first priority before training numbers of teachers unilaterally, thus securing enough budget seems critical. The professionals also emphasize on developing specialized teaching materials that include diverse inter-related subjects such as science technology, engineering, arts and humanities and social science with diverse viewpoints and advanced technology. This work requires a STEAM network for teachers to link up and share their materials, documents and experiences. It is necessary to get corporations, universities, and research centers participated in the network. (3) With respect to direction, it is necessary to propose policy that makes STEAM education ordinary and more practical in the present education system. The professionals have recommended training sessions that help develop creative thinking and amalgamative problem-solving techniques. They require reducing the workload of teachers and changing teachers' perspectives towards STEAM. They further urge a tight cooperation between departments of the government related with STEAM.

In this paper, images are automatically acquired to control the initial disease of strawberries among facility cultivation crops, and disease analysis is performed using the EfficientNet model to inform farmers of disease status, and disease diagnosis service is proposed by experts. It is possible to obtain an image of the strawberry growth stage and quickly receive expert feedback after transmitting the disease diagnosis analysis results to farmers applications using the learned EfficientNet model. As a data set, farmers who are actually operating facility cultivation were recruited and images were acquired using the system, and the problem of lack of data was solved by using the draft image taken with a cell phone. Experimental results show that the accuracy of EfficientNet B0 to B7 is similar, so we adopt B0 with the fastest inference speed. For performance improvement, Fine-tuning was performed using a pre-trained model with ImageNet, and rapid performance improvement was confirmed from 100 Epoch. The proposed service is expected to increase production by quickly detecting initial diseases.

The purpose of this study was to develop the psychology-based naturalistic competency curriculum so that forest-related experts could fully play the role of a mediator between nature(forest) and human(visitors). The curriculum was designed in three parts: a pleasant life, a wise life, and a meaningful life. Contents were focused on recognizing and naming one's senses and emotions in nature, discovering nature-related memories and Naturalistic Intelligence, experiencing the flow in nature and activating the Default Mode Network. The curriculum supplemented by expert's advice was implemented as job training for forest-related experts, and the curriculum was finally revised by examining the understanding and utilization of the participants. As a result, the curriculum in three areas of emotion, cognition, and practice was completed. It is expected that this curriculum will be upgraded through evaluation in the future so that forest-related experts can provide more qualitative service by strengthening their naturalistic competency.
