In the smart education era, it is crucial for the teacher to make lecture materials in the form of 3D convergence contents for themselves. In this study, we developed an interactive authoring tool to create 3D convergence contents for the teacher. The proposed system was implemented based on a commercial 3D engine for practicality. To evaluate the usability of the tool, we conducted a satisfaction survey of a focus group. As a result, we concluded that the proposed authoring tool was useful to create desired contents but rather complicated to use due to the text-based script editor. In the following research we will improve the editor so that it can be used in a more intuitive manner.

The purpose of this study is to develop an evaluation tool for map-based data visualization platforms and to conduct heuristic usability evaluations on existing platforms representing inter-regional information. We compared and analyzed the usability evaluation criteria of map-based platforms from the previous studies along with Nielsen's (1994) 10 usability evaluation principles. We proposed nine evaluation criteria, including (1) visibility, (2) representation of the real world, (3) consistency and standards, (4) user control and friendliness, (5) flexibility, (6) design, (7) compatibility, (8) error prevention and handling, and (9) help provision and documentation. Additionally, to confirm the effectiveness of the proposed criteria, four experts was invited to evaluate five domestic and international map-based data visualization platforms. As a result, the experts were able to rank the usability of the five platforms using the proposed map-based data visualization usability evaluation criteria, which included quantified scores and subjective opinions. The results of this study are expected to serve as foundational material for the future development and evaluation of map-based visualization platforms.

To evaluate the quality of clone detection tools, we should know how many clones the tool misses. Hence we need to have the standard code-clone reference corpus for a carefully chosen set of sample source codes. The reference corpus available so far has been built by manually collecting clones from the results of various existing tools. This paper presents a tree-pattern-based clone detection tool that can be used for automatic generation of reference corpus. Our tool is compared with CloneDR for precision and Bellon's reference corpus for recall. Our tool finds no false positives and 2 to 3 times more clones than CloneDR. Compared to Bellon's reference corpus, our tools shows the 93%-to-100% recall rate and detects far more clones.

Recently, web casting on the internet has been expanding in number and size. Web Casting is different from the conventional television broadcasting since it can transmit various types of information through multimedia and it also can include interaction between users and broadcasting server. User experience by interaction becomes more important. Therefore, it is needed to win over customers by supplying satisfied experience through creative and different services, especially when there are consider competitions among music casting sites. In order to know how to make customers satisfied, we have to try to inspect what real customers in the Web Sites are acting and thinking, namely 'customer experience'. The 'customer experience' means every experience what users are expecting, doing, thinking and feeling when they stay in the Web site and online. In this thesis, the evaluation Guideline for music casting websites is developed by understanding customer experience on the music casting websites. The process of understanding customer experience was implemented through user observation methods, such as web Diary, group interview, and questionnaire. As a result of the study, 67 evaluation Guidelines with weight rate in 6 categories which are searching music, listening music, music video, music broadcasting, music mailing and other contents are developed. It can be used to analyze strengths and weakness of music casting sites and to establish business strategy for the more satisfied customer experience.

자가통제평가(CSA : Control Self Assessment)는 핵심사업 목적을 달성하는데 개입되는 위험 그리고 그러한 사업위험을 관리하기 위하여 설계된 내부통제를 공식적이고 문서화된 협력적 프로세스에 의하여 검토하기 위하여 사용되는 방법론이다. 현재 많은 기업에서 효과적인 조직통제와 비즈니스 프로세스 개선을 위하여 전문 감사인과 경영인들이 기업지배구조 조직의 강력한 위험관리 도구로서 자가통제평가의 필요성을 강조하고 있다. 자가통제평가는 해당 조직의 담당부서나 팀에서 내부통제평가를 통하여 내부통제상의 재무보고, 준법, 사업 및 운영상의 효율성 등을 확보하기 위해서 설치되며, 효과적인 모니터 장치로서 기업지배구조상의 업무 프로세스를 정비하고 업무에서 발생하는 제반 정보의 흐름을 원활하게 해서 조직에게 손해가 발생할 수 있는 여러 가지 위험으로부터 회사를 사전에 차단하는 기능을 한다. 이러한 부분에서 효과적인 자가통제평가 시스템을 구축하는 것이 중요할 것이다. 본 연구에서는 e-Business 관련 기업지배구조의 안전성을 확보하기 위한 자가통제평가 모델에 대한 개발 필요성과 관련 자가통제평가 세가지 기본 모델들을 통하여 장단점을 제시하고, 자가통제평가 모델의 필요성을 논의하였다.

This study is an analysis on the needs assessment of school library facilities in Korea. After exploring KLA's Standards for Korean Libraries, IFLA's School Library Guidelines and AASL's Empowering Learners, the needs assessment tool of school library facilities was proposed in the previous study. The tool contains 10 major properties on school library facilities. This study gathered data from 507 students and 134 teacher librarians. The result of analysis is as follows: Students and teacher librarians evaluated the importance of library facilities more highly than the current level of facilities. Collection access, convenience and space are revealed more important properties to students and good environment, expandability, collection access are more important to teacher librarians among the properties.

피어리뷰(Peer Review)는 17세기 학술지가 만들어진 이래 오늘날까지 가장 널리 사용되는 논문의 질적인 수준과 학술지 게재 여부를 판단하는 전통적인 평가도구이다. 그러나 피어리뷰의 과정에서 발생되는 공정성 저해와 학술출판 분야에서 오픈 액세스 (OA, Open Access) 저널이 계속적으로 증가하는 디지털 미디어 시대에서 소수의 전문가가 검증하는 피어리뷰 시스템에 관한 불만들이 제기되면서 현 피어리뷰 시스템의 새로운 대안으로 오픈 피어리뷰(Open Peer Review)가 제시되기도 하였다. 이에 본 연구에서는 피어리뷰의 이론적 배경을 살펴보고 이를 토대로 새로운 대안으로 떠오르고 있는 오픈피어리뷰의 평가도구로써의 활용가능성에 대하여 살펴보고자 한다.

광원별로 형광등 32W 3등을 사용한 터널과 고압나트륨 램프 100W를 사용한 터널, 그리고 저압나트륨 램프 36W와 91W를 혼용한 터널의 조도 및 휘도를 측정한 결과 조도 및 휘도의 균제도는 3 가지 광원이 모두 거의 일치하였으나, 평균 조도와 정균 휘도값에 있어서 저압나트륨 램프를 사용한 터널이 절반 수준이 되는 차이를 보였다. 또한 경제성 평가 도구인 WEELS를 이용하여 터널의 길이를 300[m], 터널 폭을 10.7[m]로 일정하게 하여 경제성을 평가한 결과, 연간 비용에 있어서 고압나트륨 100W가 비용이 가장 켰고, 그 다음이 형광등 32W 3등용, 그 다음이 저압나트륨(36W+91W)이었지만 그 값은 근소한 차이였다.

모바일 디바이스가 기존이 PC 시장규모를 압도하면서 기하급수적으로 많은 모바일 앱이 출시되고 있다. 수많은 모바일 앱 중에서 사용자들은 배우기 쉽고, 직관적으로 사용하기에 용이한 모바일 앱을 선택하려는 경향을 보인다. 그러나 모바일 앱 사용성의 중요성이 증대됨에도 불구하고 모바일 앱에서의 사용성에 대한 연구는 미미한 실정이다. 현 GUI 사용성 테스트는 많은 시간이 소요되고 주관적인 평가에 의존하는 단점이 존재한다. 본 논문은 사용자들이 앱을 조작하는 터치 입력 데이터를 기반하여 EFSM(Extended Finite State Machine)에 인자를 추가한 형태로 모델링 후 개발자의 예상 시나리오와 비교하여 GUI 사용성 저해요소를 검출하는 기법을 제안하고 있다. 이와 같은 반-자동화된 방법을 통해 모바일 앱 상에서의 사용성을 측정할 수 있다. 제안된 기법을 구현한 도구의 구조를 설명하고 사용성 저해 요소 검출하는 과정을 기술하였다.

This study was to develop the Medication Adherence Scale in Elderly (MAS-E) with chronic disease and verify its reliability and validity. The MAS-E was developed in 5 steps: Configuration of conceptual frame by content analysis, preliminary items, pilot study, reliability and validity test, and development of final MAS-E with chronic disease. The questionnaires were collected from 345 adults with one-to-one interviews. Verification of its reliability and validity was divided into two phases. Reliability was tested using Cronbach's alpha, split-halves reliability, and test-retest. For validity tests, item analysis, factor analysis, total score-factor score correlation analysis, and criterion related validity were used. The developed scale consisted of 18 items and 4 factors - remember of taking medication (2 items), expectations for drug effects (5 items), practice taking medication according to instructions (8 items), communicating with health professionals (3 items), and explained 69.7% of total variance. The scale had significantly positive correlation (r = .72, p <.001) with the Morisky Medication Adherence Scale (MMAS-8). Cronbach's alpha was .91, Guttman split half coefficient was .80, and test-retest reliability was .912. Finding suggest that the MAS-E is a suitable scale to assess the status of medication adherence in elderly with chronic disease.
