다중지능이론에 근거한 지리과 수행평가 도구의 개발과 적용
류혜연 ( Hye Yeon Ryu ) 한국지리환경교육학회 2008 한국지리환경교육학회지 Vol.16 No.3
이 연구에서는 언어 능력이나 논리-수학적 능력에 의존한 기존의 획일적인 평가 방식에서 벗어나 다중지능이론에 근거한 수행평가 도구를 개발하여 지리교육에 적용시켜 보았다. 다중지능 검사지를 통해 각 학생들의 강점지능을 파악하고, 그 검사 결과에 따라 (1)자신의 강점지능과 관련이 깊은 과제, (2)스스로 희망하여 선택한 선호 과제, (3)교사에 의해 임의로 부여된 무작위 과제를 각각 수행해 보도록 한 후 그 수행 과정 및 결과에 대한 분석을 통해 세 과제들 간의 관계를 밝히고, 이를 바탕으로 현장 적용과 관련하여 그 교육적 시사점을 탐색해 보았다. 가드너의 다중지능이론에 근거한 7가지 지능영역별 수행과제 및 평가를 위한 루브릭을 구안하여 적용한 결과 무작위 과제와 강점지능 과제에 비해 선호 과제의 평균 점수가 더 높게 나타났다. 이는 학생들이 자신의 흥미와 소질을 반영하여 스스로 선택한 과제에 애착을 가지고 적극적인 태도로 참여하였기 때문이다. 한편 낯설고 새로운 형태의 수행평가가 학생들에게 혼란을 가져다주기도 하였지만, 각자가 지닌 다양한 흥미와 능력을 발견하고 잠재력을 발휘할 수 있는 기회가 되었음을 확인할 수 있었다. 그러나 자기이해 지능영역의 수행과제 및 루브릭을 구안해 내지 못하였으며, 복수의 강점지능을 가진 학생들의 처리문제와 일회적 실험 결과의 일반화 등은 이 연구의 한계점이라고 할 수 있다. In this study, the performance assessment based on the multiple intelligences theory were developed and applied to the geography classes. Based on the results of multiple intelligence test, participants were asked to perform (1) a task related with one`s strength, (2) a preferred task chosen by individual student, and (3) a randomly assigned task from a teacher. This study aims to address the relationships among the three types of tasks and to find an educational implication for geography teaching. This study revealed that the mean score of preferred task was higher than those of two other tasks. It`s because the participants were more willing to carry out their preferred tasks with more actively and enthusiastically than other tasks. Although an unfamiliar and new form of assessment system brought a little confusion to the students, it helped them find their own interest, ability and the opportunity to be aware of their own potential.

전자식 엔진냉각제어 시스템을 위한 팬 클러치 특성 분석
류혜연(Hye-Yeon Ryu),김현희(Hyun-Hee Kim),정성민(Sung-Min Jeong),고영호(Young-Ho Koh),이경창(Kyung-Chang Lee) 한국산업융합학회 2018 한국산업융합학회 논문집 Vol.21 No.5
The engine cooling system is a device that keeps the temperature of the engine room at a proper level by driving the cooling fan when the engine room temperature that occurs during driving is above a certain temperature. Recently, the vehicle cooling system has been changed to electronic system. Therefore, in this paper, we will analyze the clutch operation characteristics for designing a superior electronic fan clutch. For this purpose, an electronic fan clutch was designed and a test bed for performance evaluation was constructed and analyzed.

The Juvenile Investigation system has its role as a standard data of judicial judgment that can help young offenders to be protected, educated, and civilized. Additionally, by taking advantage of the recidivism risk assessment at the time of investigation, it is possible to predict the tendency of re-offense and the effects that can help preventing crimes in advance. Although the rate of recidivism is steadily increased, the Juvenile Investigation system is not changed but maintained its state as before. The purpose of this paper is not only to study the contents of the juvenile investigation system and its current situation in South Korea and abroad, but examine a few different types of programs related to recidivism risk and its current situation as well. It turned out that the investigation system which was supposed to be carried out sufficiently in various stages of the judicial system that actually has not enough rate of conduct due to the problem of lacked investigators and some other reasons. Even though there are professional investigation tools that have been verified enough, such tools were not being used properly and enough. At the end, it is concluded that what we need to pursue is proper intervention of experts, adequate training for investigators, and accurate usage of the tools.

전륜 옴니휠을 적용한 자세 변환 휠체어의 설계 및 구현
류혜연(Hye-Yeon Ryu),권제성(Je-Seong Kwon),임정학(Jeong-Hak Lim),이경창(Kyung-Chang Lee) 한국기계가공학회 2021 한국기계가공학회지 Vol.20 No.9
In this paper, an omni wheel-based electric wheelchair is proposed that can achieve safe and convenient movement and can improve the convenience of living for mobility-impaired people who cannot move on their own. Generally, mobility-impaired people are afflicted with physical health issues such as pain and secondary body deformities because they often remain seated in wheelchairs for long periods of time. Hence, an electric wheelchair is required whose posture can be changed and whose size can be adjusted according to the user’s body type. Such a wheelchair should also facilitate easy change of direction (even in a narrow space) for convenient movement. In this paper, an electric wheelchair featuring omni wheels is proposed that allows posture transformation and facilitates movement in a narrow space. It is believed that the proposed wheelchair can aid in enhancing the convenience of living for mobility-impaired people.

전기 자동차용 Brake-By-Wire 시스템을 위한 전자식 브레이크 구현
류혜연(Hye-Yeon Ryu),정기민(Ki-Min Jeong),김만호(Man-Ho Kim),이경창(Kyung-Chang Lee) 한국산업융합학회 2017 한국산업융합학회 논문집 Vol.20 No.4
As vehicles become more intelligent this is focused on ways to enhance safety and convenience for both drivers and passengers. In particular, x-by-wire systems that replace rigid mechanical components with dynamically configurable electronic elements are being developed to expand intelligent functions, such as adaptive cruise control or lane departure warning system. Because the malfunction of safety-related modules controlling critical functions, such as brakes, throttle, and steering in x-by-wire systems, can cause injury or death, safety and reliability are the most critical issue for automotive vendors and parts manufacturers. In an effort to develop better and effective brake-by-wire system, this paper presents EMB system by using the low speed electric vehicle, which is not required large braking force, with motor controller. In addition, we design performance evaluation system of EMB with 1/4 low speed electric vehicle model and suggested EMB is evaluated through the performance evaluation system.
