이희승 ( Lee¸ Heeseung ) 한국피아노교수법학회 2021 음악교수법연구 Vol.22 No.2

코로나 19의 영향으로 인한 온라인 학습이 2020학년도 1학기부터 일반적인 학습 형태로 행해지는 현 상황에서, 계속되는 학습자들의 온라인 학습 수행으로 야기되는 다양한 문제점들을 고려하지 않을 수 없다. 비대면 수업뿐 아니라 면대면 수업에서도 교수자와 학습자 사이의 상호작용은 학습 목표를 위한 필수조건으로 비록 비대면 수업일지라도 온라인 수업에서의 다양한 채널을 통한 교수자와의 소통은 효과적인 학습을 위하여 간과할 수 없는 요소라고 할 수 있을 것이다. 선행연구들을 통하여 교수자와의 라포(친밀감) 형성은 학습 성과에 긍정적인 영향을 미칠 수 있음이 밝혀져, 교수자들에게 보다 효율적인 온라인 학습에서의 교육 지침을 위한 연구를 수행하였다. 본 연구를 위하여 2020학년도 2학기부터 2021학년도 1학기까지 수도권에 위치하고 있는 4개의 음악대학에서 학부생 및 대학원 학생들(N=96)을 대상으로 교수자와의 라포 형성, 자기효능감, 그리고 수업 만족도에 관한 인식조사와 더불어 변인 간의 관계성 고찰을 위하여 상관관계분석과 매개효과검증 분석을 실시하였다. 연구결과, 상관관계분석을 통하여는 자기효능감과 라포 형성, 수업 만족도와 라포 형성, 수업 만족도와 자기효능감 모두 유의한 정적 상관관계를 나타났으며 매개효과검증 분석 결과로, 자기효능감이 교수자와의 라포 형성에 영향을 미치는 것으로 나타났다. Due to the influence of covid-19, we cannot help but consider the various problems caused by continuing learners’ online learning in the current situation where online learning has been conducted in the general form of learning from the first semester of 2020. In non-face-to-face classes as well as face-to-face classes, interaction between professors and learners is a prerequisite for learning goals, even if they are non-face-to-face classes. Prior studies have shown that building rapport with professors among various interactions in learning could have a positive impact on learning performance. Based on this, for undergraduate and graduate students (N=96) majoring in piano performance at four music universities located in the Seoul metropolitan area from the second semester of 2020 to the first semester of 2021, the survey has been conducted to identify preception as well as the relationship among building rapport with professors, self-efficacy and course satisfaction. For this study, pearson’s correlation analysis and mediated effect verification have been conducted. As a result, correlation analysis showed that self-efficacy and building rapport, course satisfaction and building rapport, course satisfaction and self-efficacy showed significant static correlations. Mediated effect verification shows that self-efficacy affects building rapport with professors.

Heeseung Choi,김정은,방경숙,박연환,이남주,김찬희 한국간호과학회 2015 Journal of Korean Academy of Nursing Vol.45 No.6

Purpose: An emerging trend in Asian higher education is English-medium instruction (EMI), which uses English as the primary instructionallanguage. EMI prepares domestic students for international leadership; however, students report difficulty in learning,and educators have raised questions concerning the effectiveness of EMI. The flipped learning model (FLM), in which lecture andhomework activities for a course are reversed, was applied to an English-medium course offered by a college of nursing in Korea. The aims of this study were to: 1) revise an existing English-medium nursing course using the FLM; 2) explore students’ learning experiencesand their acceptance of the FLM; and 3) identify key factors in the success of FLM. Methods: We used a descriptive,cross-sectional, mixed-methods design and the participants were students at one nursing school in Korea. A series of course developmentmeetings with faculties from the nursing school and the center for teaching and learning were used to develop the courseformat and content. We conducted course evaluations using the Flipped Course Evaluation Questionnaire with open-ended questionsand focus group interviews. Results: Students (N=75) in a 15-week nursing course responded to a survey after completing thecourse. Among them, seven students participated in one of two focus groups. Overall, students accepted and favored the flippedlearning strategy, and indicated that the method enhanced lecture content and their understanding of it. Factors associated witheffective instruction included structured monitoring systems and motivational environments. Conclusion: The FLM requires sufficientpreparation to facilitate student motivation and maximize learning outcomes.

Heeseung Choi(최희승),Sumi Kim(김수미),Heesung Ko(고희성) 대한스트레스학회 2020 스트레스硏究 Vol.28 No.3

본 연구는 부모-자녀 관계와 관련된 양적 변수에 따라 구분된 각 그룹들에서 부모자녀 갈등의 주제, 갈등상황에서 부모의 인식과 반응의 질적인 차이를 확인하고자 시도되었다. 국내 5개 도시에서 청소년 자녀를 둔 부모 103명이 부모효능감, 부모-자녀 의사소통, 부모-자녀 관계, 부모-자녀 갈등, 부모스트레스 관련 온라인 설문에 참여하였고, 이들은 청소년 자녀와의 갈등상황을 직접 기술하였다. 5개 변수의 군집분석결과 두 개의 그룹으로 분류되었고 두 그룹의 부모들은 모두 청소년 자녀와 갈등상황에서 실망, 분노, 걱정, 좌절 등의 감정을 경험하였으나 갈등을 인식하고 반응하는 양상에서는 차이가 있었다. 본 연구결과는 향후 부모자녀 관계를 향상시키기 위한 부모교육프로그램 구성의 기초자료가 될 것이다. Background: Understanding how parents cognitively and emotionally perceive and respond to parent-child conflicts would provide a basis for targeted and effective parent education programs. The specific aims of this online mixed methods research study were to (1) categorize parents of adolescents based on their level of parental self-efficacy, parent-child communication, parent-child relationships, parent-child conflicts, and parental stress; and (2) explore parent-child conflict situations and parents’ perceptions and responses to them in each group. Methods: A total of 103 parents with adolescent children aged 11∼16 years were recruited from five cities in Korea to participate in the study. Participants completed an online questionnaire about parent-child relationships and described a parent-child conflict situation that occurred within the past week and their perceptions and responses to it. We used cluster and content analyses for quantitative and qualitative data, respectively. Results: The study revealed two clusters: adequate parent-child relationship (group 1) and inadequate parent-child relationship (group 2). The key variable distinguishing the two groups was parental self-efficacy. Although parents in both groups generally experienced frustration, anger, worry, discouragement, and disappointment in the conflict situations, the two groups differed in their perceptions and responses to these situations. Conclusions: Results suggested that parent education programs should focus on improving parental self-efficacy. Additionally, the programs should provide an opportunity for parents to practice self-reflection, help them understand the link between emotion-thought-behavior based on cognitive model, and thus, effectively manage parent-child conflict situations.

Improving the startup time of digital TV

Heeseung Jo,Hwanju Kim,Hyun-Gul Roh,Joonwon Lee IEEE 2009 IEEE transactions on consumer electronics Vol.55 No.2

<P>Digital TV was introduced with promises for higher quality displays and converging Internet services which require more computing power and complex software systems. Such complexity entails a prolonged startup time that is similar to booting a computer system. In this paper, we propose two approaches to reduce the startup time of digital TV. Based on the suspend-resume technique employed in many commodity operating systems, our mechanisms replace the cold startup process of digital TV with the resuming from a suspend image. We also analyze the bottlenecks in the startup process and suggest hardware supports to improve the startup time. The proposed approaches reduce the startup time of digital TV by about 50%.</P>

Mosaicing Touchless and Mirror-Reflected Fingerprint Images

Heeseung Choi,Kyoungtaek Choi,Jaihie Kim IEEE 2010 IEEE transactions on information forensics and sec Vol.5 No.1

<P>Touchless fingerprint sensing technologies have been explored to solve problems in touch-based sensing techniques because they do not require any contact between a sensor and a finger. While they can solve problems caused by the contact of a finger, other difficulties emerge such as a view difference problem and a limited usable area due to perspective distortion. In order to overcome these difficulties, we propose a new touchless fingerprint sensing device capturing three different views at one time and a method for mosaicing these view-different images. The device is composed of a single camera and two planar mirrors reflecting side views of a finger, and it is an alternative to expensive multiple-camera-based systems. The mosaic method can composite the multiple view images by using the thin plate spline model to expand the usable area of a fingerprint image. In particular, to reduce the affect of perspective distortion, we select the regions in each view by minimizing the ridge interval variations in a final mosaiced image. Results are promising as our experiments show that mosaiced images offer 29% more true minutiae and 28% larger good quality area than one-view, unmosaiced images. Also, when the side-view images are matched to the mosaiced images, it gives more matched minutiae than matching with one-view frontal images. We expect that the proposed method can reduce the view difference problem and increase the usable area of a touchless fingerprint image. Furthermore, the proposed method can be applied to other biometric applications requiring a large template for recognition.</P>

Conceptual Design of a New Stair-Climbing Mobile Platform Using a Hybrid Link Mechanism

Heeseung Hong,Jangho Bae,Jongwon Kim,Hwa Soo Kim 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10

High mobility performance is the most important key to mobile robots. In this research, a new indoor stair-climbing mobile platform is proposed on the basis of a hybrid-link mechanism. The hybrid link mechanism combining the passive link with the active mechanism can guarantee well-balanced simplicity as well as adaptability performance in comparison with the previous passive mechanisms. First, a requirement list for a stair-climbing indoor mobile platform is made upon the related researches. Then, a new kinematic model of hybrid link mechanism is suggested by using systematic design methodology. For the optimization of design parameters such as wheel radii and link lengths, the cost function is chosen as the combination of the backward movement and the deviation of path angle during climbing up stairs. Then, the optimization of the kinematic variables for the hybrid link mechanism is carried out via generic algorithm.
