Evaluation learning based on code testing is becoming a popular solution in programming education via Online judge(OJ). In the recentpast, many papers have been published on how to detect plagiarism through source code similarity analysis to support OJ. However,deep learning-based research to support automated tutoring is insufficient. In this paper, we propose Input & Output side FiLM modelsto predict whether the input code will pass or fail. By applying Feature-wise Linear Modulation(FiLM) technique to GRU, our model canlearn combined information of Java byte codes and problem information that it tries to solve. On experimental design, a balanced samplingtechnique was applied to evenly distribute the data due to the occurrence of asymmetry in data collected by OJ. Among the proposedmodels, the Input Side FiLM model showed the highest performance of 73.63%. Based on result, it has been shown that students cancheck whether their codes will pass or fail before receiving the OJ evaluation which could provide basic feedback for improvements. 온라인 저지 시스템 지원하기 위한 표절 검사, 소스코드 분석 및 자동화된 튜터링 기법이 연구되고 있다. 최근 딥러닝 기술 기반의 소스코드유사도 분석을 통한 표절 감지 기술들이 제안되었으나, 자동화된 튜터링을 지원하기 위한 딥러닝 기반의 연구는 미흡한 실정이다. 따라서 본 논문에서는 자바 바이트코드와 문제정보를 결합하여 학습하고, 학습자가 온라인 저지 시스템에 코드를 제출하기 전에 pass/fail 여부를 예측할 수 있는GRU 기반의 Input / Output side FiLM 모델을 제안한다. 또한 온라인 저지에 수집되는 데이터의 특성상 비대칭이 발생하기 때문에 밸런스 샘플링기법을 적용하여 데이터를 균등하게 분포시켜 두 상황을 제안한 모델로 학습하였다. 실험 결과 Input side FiLM 모델이 가장 높은 73.63%의 성능을보였다. 이를 기반으로 학습자들이 온라인 저지의 평가를 받기 전에 pass/faill 여부를 확인하여 소스코드 개선에 대한 피드백 기능에 적용 가능할것으로 예상된다.

제천시 문화예술축제 현황과 제언

현경석 세명대학교 지역문화연구소 2016 지역문화연구 Vol.15 No.1

특정한 지역사회의 문화와 예술에 대하여 논의하고자 할 때에는 먼저 그 지역의 오랜 역사와 관습, 시민의식은 물론 지리적 조건이나 환경에 대한 조사연구가 우선되어야 한다. 제천 시는 지리적으로 전국토의 중앙에 위치하고 있으나 태백과 소백, 월악으로 이어지는 고산지대로 문화예술이 발달하기에는 척박한 조건을 가졌다. 전체면적의 74%가 산으로 둘러싸여 자연풍광이 아름답고 풍부한 자원과 민족 문화유산이라 할 의림지와 박달재가 있을 뿐 아니라 제천의병 정신의 고장이다. 문화예술에 대한 관심도 높아 일찍이 의병제와 박달제(가요제)는 물론 청풍호 벚꽃축제와 동계민속축제, 금요음악회(‘힐링콘서트’로 개명), 국제음악영화제, 한방바이오축제 등 다양한 축제를 개최하고 있다. 행사별로 다양한 의견들이 없지 않지만 역사성과 방향성을 정립하고 시민들과의 합의를 도출하기 위한 부단한 노력은 일단 평가의 여지가 있다. 다만 문화예술적 가치로 완성되지 못하고 일회성 축제로 머물러 있는 현실의 문제는 무엇보다 전문가 부재의 현상이라 하겠다. 박물관, 미술관 하나 없고 공연장도 사람도 예산조차 부족한 현실에서 전문가를 발굴하고 육성하기 위한 집중적인 투자 없이 문화예술의 발전은 요원하다 할 것이다. 결론적으로 1)시민들의 적극적 참여를 유도하고 타 도시 축제와의 차별화, 특성화를 통한 정체성 확립, 2)문화예술에 대한 관민의식의 전환- 오랜 투자와 열정이 있어야 성취 가능, 3)과감한 변화와 개선을 통한 생산적, 발전적 축제를 향한 노력부족, 4)철저한 사후평가제 도입, 5) 대소공연장 확보, 편의시설 부족 등 개선, 6)전문가의 발굴 육성으로 창조적 프로그램 개발 등이 시급하며, 특히 문화재단의 설립에 중지를 모우고, 눈앞의 경제논리를 뛰어넘는 문화예술회관 신축 등에 과감한 결정을 제안한다. 아울러 소극장 운동을 활성화하여 제반 문화예술 활동에 활력을 도모하고 지역소재 대학과의 긴밀한 윈윈전략으로 대학의 사명과 역할을 이끌어내는 특단의 노력이 필요하다. 이를 위하여 대학 안에 설립된 ‘지역문화연구소’ 같은 전문기구를 통한 고급인력의 참여와 역할을 강화 유도하는 정책을 수립 운영할 필요가 충분하다. 젊음의 열정과 패기가 캠퍼스를 달구고 지역사회 확산되는 선순환 구조야말로 지역사회 문화예술의 활성화와 발전을 담보하는 첩경이다. When discussing the culture and the arts of a specific community, research and study of geographical conditions and the environment as well as the long history, customs and civic consciousness of the area must be done first. Although Jecheon is located in the center of the nation geographically, it has a harsh condition for the development of culture and art as a high mountain area that leads to Taebaek, Sobaek and Wolak. Because 74% of the total areas are surrounded by mountains, its natural scenery is beautiful and it also has abundant resources, Uirimji and Bakdaljae that can be said as ethnic cultural heritage, as well as the spirit of faithful army of Jecheon memorial service. With much interest in culture and arts, there are many festivals including Cheongpungho Cherry Blossom Festival, Winter Folk Festival, Friday Concert (renamed as "Healing Concert"), International Music Film Festival and Oriental Biotechnology Festival as well as faithful army of Jecheon memorial service and Bakdalje (song festival). Although there are many opinions on each event, the constant efforts to establish history and direction and to reach consensus with the citizens leave room for evaluation. However, the problem of present situation, which is not completed as cultural and artistic values and just remains as a one-time festival, is mainly because of a phenomenon of absence of experts. Under the situation without a museum, an art museum, a theater and people and even lack of budget, the development of culture and arts would be difficult without the intensive investment to discover and nurture professionals. In conclusion, the researcher proposes to execute urgently: 1) To induce citizen's active participation, to differentiate from other city festivals and to establish identity through characterization; 2) to transform consciousness of the government and the people on culture and art achievable only with long-term investment and enthusiasm; 3) to improve the problem of lack of effort toward productive and developmental festivals through bold changes and improvement; 4) to introduce a thorough post evaluation system; 5) to secure large or small scale performance facilities and to improve lack of convenient facilities; and 6) to develop creative programs by finding and cultivating experts. In particular, we have to ask advice from many people for the establishment of the cultural foundation and make bold decision to build the new culture and arts center beyond the immediate economic argument. In addition, it is necessary to make a special effort to revitalize the activities of small arts theater and to revitalize various cultural arts activities and to lead the university's mission and role through a close win-win strategy with local universities. To this end, it is necessary to establish and operate a policy that encourages the participation and role of high-level human resources through specialized organizations such as 'Regional Culture Institute' to be established in the university. The virtuous cycle structure in which the passion and ambition of youth grow on the campus and spread to the community is the quick way to secure the activation and development of local culture and arts.

호텔 서비스의 물리적 환경, 고객 가치,행동 의도의 구조적 관계에 관한 연구

현경석,한진수 한국관광학회 2009 관광학연구 Vol.33 No.2

This study examines the influence of hotel service's physical environment on customer value and behavioral intention. Physical environment included ambient, design and social factor. Customer benefit consisted of service quality and emotional response, and customer cost was made up of monetary cost and non-monetary cost. The data were collected from 300 travelers accommodated in five-star hotels in Jeju island and structure equation modeling(SEM) was used as method of analysis. The results suggested that the relationship between physical environment and customer benefit as well as customer cost was partially significant . Moreover, customer benefit and customer cost influenced customer value, and customer value affected on behavioral intention.

Current Status and Developments of Comparative Education at Universities in Korea and World Wide

현경석,박애리 한국비교교육학회 2008 比較敎育硏究 Vol.18 No.4

The purpose of this study is to present the overall landscape of Comparative Education study in teacher training program at universities in Korea. The Comparative Education in Korea is relatively young without a lengthy tail on its name and still on the way of upgrading itself, however various efforts are gathering for the development of Comparative Education. With this understanding, this paper diagnoses the current status of Comparative Education in Korea by analyzing 1) the number of institutions which provide Comparative Education lectures for their teacher training program, 2) aims of Comparative Education teaching, 3) curricular and course titles, 4) teaching methods and textbooks, and 5) current issues and problems currently laid on Comparative Education in Korea designated by actual lecturers and professors who are in charge of Comparative Education lectures. The historical development of Comparative Education in Korea will be briefly presented at the beginning part of the chapter. To gauge the comparative position of Korean Comparative Education, the second half of this paper introduces the cases of Comparative Education at universities worldwide, presenting various countries' status of Comparative Education along with their developmental status. As the first research which pays an attention on the current figure of Comparative Education in Korea, it will form an impetus on why we should teach college students about comparative education and on what next step should be carried for further development of Comparative Education at universities based on the comparative understanding of other countries. Since it is in the transitional stage in terms of its development, it would be critical to have a self-analysis of the current status, which will help to lay the comprehensive understanding background for designating the future direction of its development.
