( Jungin Kwon ),( Jaehyoun Kim ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.8

The software centered world following the fourth industrial revolution is rapidly approaching us. Countries around the world attach importance to software's ability as one of the key elements for training future human resources. In order to train software centered human resources, each university has designated Software Education as an essential curriculum for not only major but also non-majors. In the past Software Education was an education for a major, but recent Software Education was changed to the essential education that is necessary for all living in the software centered world. In the past the curriculum was focused on software development and implementation-oriented education, but recent curriculum emphasizes sequential arranging and thinking of problem solving. In order to reflect trends in recent Software Education in detail, we integrate Software Education with major concept of Computational Thinking. In this paper, we analyzed the effect of the main concept of Computational Thinking on Software Education for non-majored learners who received Software Education based on Computational Thinking (here refers to learners who major in humanities, social sciences and arts). In addition, research models of satisfaction, self-efficacy, and occupational change was established as the elements of Software Education, and it was found that there was a relation between Computational Thinking and Software Education.

고령인구 및 장애인구가 증가함에 따라 평등하고 안전한 환경을 형성하기 위한 유니버설 디자인의 중요성이 더욱 부각되고 있다. 특히 문화체험에 대한 욕구가 증대되어 국가적 차원에서 문화공간에 대한 투자와 구축이 활발하게 진행되고 있으나, 사회적 약자들은 공공시설에서 문화체험을 하기에는 제한적 요소가 많다. 이러한 요소를 분석하기 위해 공공문화공간인 박물관 구축 환경을 시각장애인과 비장애인의 측면에서 현황조사 및 사용 평가 분석을 시행하였다. 문헌연구를 통해 유니버설 디자인의 개념과 원리를 이해하고 기존의 평가요소를 분석하여 재분류하였다. 분석된 평가요소를 기준으로 국내 박물관을 평가한 결과 시각장애인의 박물관 관람을 위한 정보 및 환경, 서비스의 보완할 점을 파악하고 개선방향을 도출하였다. 본 연구는 이러한 사회적 약자를 배려하고 모두가 쾌적하게 활동할 수 있는 환경 구축을 위한 평가요소와 개선방향을 제안하고자 한다. As the elderly and the disabled populations increase, the importance of the universal design is more highlighted to form equal and secured environment. Particularly, as the desire for the cultural experience has grown, investment and construction of the cultural space are actively carried forward at the state level, but there are a lot of restrictive elements for the disadvantaged to have the cultural experience in the public facilities. To analyze these elements, investigation into the present conditions and analysis of use evaluation were conducted over the construction environment of museums, the public cultural space, in terms of the visually handicapped and non-handicapped people. Through the literature review, this study understood the concept and principle of the universal design, analyzed and reclassified the existing evaluation elements. As a result of evaluating museums in the country based on the analyzed evaluation elements, the information, environment and supplement points in service were investigated for the visually handicapped to tour museums and remedies were drawn. This study tries to consider these disadvantaged and to suggest evaluation elements and remedies for environment construction, so that everyone can do pleasant activities.

권정인 ( Jungin Kwon ),김재현 ( Jaehyoun Kim ) 한국컴퓨터교육학회 2017 한국컴퓨터교육학회 학술발표대회논문집 Vol.21 No.2

현재 디지털문화사회의 교육은 개인정보, 저작권 등 특정 영역에만 국한되어 있어 정작 디지털 네이티브가 매일 접하는 디지털리터러시에 관한 교육은 미비한 상태이다. 본 연구에서는 티지털네티즌 중 중고등학생들의 디지털리터러시에 대한 인식을 조사하고 디지털 문화사회에 필요한 디지털 리터러시 교육의 체계적 양성의 근원적 대책을 하면하고자 한다.

Computational Thinking기반 SW교육과 문제해결력에 관한 연구

권정인 ( Jungin Kwon ),김재현 ( Jaehyoun Kim ) 한국컴퓨터교육학회 2017 한국컴퓨터교육학회 학술발표대회논문집 Vol.21 No.1

미래사회의 핵심역량을 갖춘 인재양성의 주요 키워드로 창의성과 문제해결력의 중요성이 언급되면서Computational Thinking기반의 사고가 중요한 이슈로 떠오르고 있다. 본 연구에서는 비전공자들을 위한 Computational Thinking기반의 SW교과목을 개발한 후, 16주간 비전공자들에게 기초SW교육을 실시하였다. 이후 비전공자들의 문제해결 능력의 향상을 위해 Computational Thinking의 주요개념이 문제해결 능력의 향상에 핵심 요소임을 도출하였다. 이 결과를 바탕으로 Computational Thinking의 주요개념을 바탕으로 한 SW교육이 문제해결과정의 단계별 체계화에 영향을 미칠 수 있는지의 여부에 대해 조사하고자 한다.

정신피로와 음성특징과의 상관관계 측정

김정인(Kim, Jungin),권철홍(Kwon, Chulhong) 한국음성학회 2014 말소리와 음성과학 Vol.6 No.2

This paper deals with how mental fatigue has an effect on human voice. For this a monotonous task to increase the feeling of the fatigue and a set of subjective questionnaire for rating the fatigue were designed. From the experiments the designed task was proven to be monotonous based on the results of the questionnaire responses. To investigate a statistical relationship between speech features extracted from the collected speech data and fatigue, the T test for two-related-samples was used. Statistical analysis shows that speech parameters deeply related to the fatigue are the first formant bandwidth, Jitter, H1-H2, cepstral peak prominence, and harmonics-to-noise ratio. According to the experimental results, it can be seen that voice is changed to be breathy as mental fatigue proceeds.

정상 음성의 목소리 특성의 정성적 분류와 음성 특징과의 상관관계 도출

김정인(Kim, Jungin),권철홍(Kwon, Chulhong) 한국음성학회 2014 말소리와 음성과학 Vol.6 No.1

In this paper voice quality of normal speech is qualitatively classified by five components of breathy, creaky, rough, nasal, and thin/thick voice. To determine whether a correlation exists between a subjective measure of voice and an objective measure of voice, each voice is perceptually evaluated using the 1/2/3 scale by speech processing specialists and acoustically analyzed using speech analysis tools such as the Praat, MDVP, and VoiceSauce. The speech parameters include features related to speech source and vocal tract filter. Statistical analysis uses a two-independent-samples non-parametric test. Experimental results show that statistical analysis identified a significant correlation between the speech feature parameters and the components of voice quality.

Dimethyl ether(DME) is an oxygenated fuel with a cetane number higher than that of diesel oil. It meets the ULEV emission regulation and reduces the smoke to almost zero when used in a diesel engine. In the present study, engine performance and exhaust emissions were' investigated with a 8 liter conventional DI diesel engine by using dimethyl ether fuel for development of medium-duty DME bus. Test results showed that the torque and the power with DME were about 70% as those of pure diesel oil, but the brake thermal efficiency decreased a little. Also, smoke index from DME engine showed nearly zero level and NOx was decreased a little compared to diesel oil.

이광수,권정인,Lee, Gwang-Su,Kwon, Jungin 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.10

초연결 지능정보사회에 빠른 진입으로 빅데이터 기반의 자원관리 등을 위한 빅데이터시스템 구축의 필요성을 대두되면서, 공공기관에서 빅데이터시스템 구축을 추진하고 있는 실정이다. 이에, 본 연구는 공공기관 현실에 맞는 빅데이터시스템 구축 시 고려해야할 측정항목을 도출하고자 한다. 고등교육기관 통합정보시스템 구축의 환경요인 측정항목에 선행연구를 기반으로 빅데이터 관련연구들의 성공요인들과 공공기관 빅데이터 시스템 구축의 특성을 분석·결합하였다. 연구방법으로는 빅데이터 전문가들을 대상으로 델파이 방법등을 사용하여 빅데이터 특성이 반영된 19개 측정항목을 도출하였으며, 이를 빅데이터시스템에 구축하고자 하는 공공기관에 성공적으로 적용하기 위한 방안을 제언하였다. 본 연구결과가 공공기관에서 성공적인 빅데이터시스템 구축의 기초 자료로 활용되기를 기대한다. As the need to establish a big data system for rapid provision of big data and efficient management of resources has emerged due to rapid entry into the hyper-connected intelligence information society, public institutions are pushing to establish a big data system. Therefore, this study analyzed and combined the success factors of big data-related studies and the specific aspects of big data in public institutions based on the measurement of environmental factors for establishing an integrated information system for higher education institutions. In addition, 19 measurement items reflecting big data characteristics were derived from big data experts using brainstorming and Delphi methods, and a plan to successfully apply them to public institutions that want to build big data systems was proposed. We hope that this research results will be used as a foundation for the successful establishment of big data systems in public institutions.
