Online game industry is also making much efforts in developing games that have emotional disposition which is rapidly growing by the increase of emotional demand by the user. In the online game development that induces immersion stimulating the emotion of the human has the evaluation stage it must surely pass, and in this stage, emotional evaluation system is known as the evaluation method that one can verify the function, usage and human emotion desire of the game before its launching. Nevertheless, at this situation the studying result is absent in the verification of efficiency and validity of the emotional evaluation system, this study is to work on the availability and validity of the emotional evaluation system as the evaluation tool of the game comparing with the Jakob Nielsen's evaluation system through common user group which are the subjects.

Achieving a certain degree of objectivity is one of main assessment priniciples to meet and self-assessment has been under-used as a formal instrument for assessing students' achievement due to lack of objectivity. Now, this research attempted to look into how students perceived self-assessment and how they engaged in the assessment process. Self-assessments and in-depth interviews with students were collected as main data sources. The results of data analysis are as follows. First, a student' perceptions of self-assessment have been observed to change over a course of a semester. Furthermore, changes in perceptions might have led students to get ownership of their learning. Conclusively, this research proposes that the research of self-assessment be accommodated into the socio-cultural context to demonstrate its desirable influence on students' learning.

인터넷 및 IT 기술의 획기적인 발전으로 인해 우리가 접하는 정보는 그 양적 측면 뿐만 아니라 질적 측면에서도 비약적인 발전을 가지고 왔다. 또한 인터넷 보급의 활성화로 대부분의 사람들은 많은 종류의 정보 속에서 그리고 다양한 형식으로 구성된 정보 속에서 지내고 있다. 특히 웹의 사용이 일상화 되어감에 따라 컴퓨터를 다루기 힘든 정보소외계층의 웹사이트 정보 접근성에 대한 관심이 증가하고 있으며 그와 관련한 다각적인 연구도 활발히 진행 중이다. 본 연구에서는 선행된 웹 사이트 접근성에 관한 연구와 한국형 자동화 접근성 평가도구의 분석을 통하여 기존의 웹 접근성 평가의 한계를 파악하고 이를 통해 새로운 유형의 웹사이트 접근성 평가모형을 제안하고자 한다. 이를 위한 접근성 평가의 효율성 및 타당성 확보를 위해 먼저 자동화 평가도구인 Kado-Wah 를 이용하여 기본 평가를 진행하였고, 그 결과를 바탕으로 웹 페이지 소스분석 및 음성합성 S/W 를 통한 메뉴얼 평가를 실시하였다. 평가결과를 바탕으로 접근성 오류정도를 산출하여 한국과 미국의 교육기관 웹사이트의 접근성을 비교 분석하고 그 결과를 통해 향후 웹 기반 정보접근에 대한 효율성을 최대화 할 수 있도록 웹 구현에 대한 지침을 제안하고자 한다.

Objective : The aim of this systematic review is to analyze the assessment items and tools used for the discharge of stroke and elderly patients and to help select appropriate assessment tools for discharge planning. Methods : The studies included in this review were collected from the PubMed, Medline Complete (EBSCOhost), and Scopus databases from January 2009 to December 2018. A total 22 studies were selected. The research types, the areas and sub-areas of assessment, as well as the assessment tools according to the areas were analyzed. Results : Descriptive research (59.2%) was the most frequent type of research. The 12 main areas of assessment were medical condition, activities of daily living, swallowing function, sensation, mobility, cognition and perception, communication, emotion, home environment, patient knowledge and readiness for discharge, social support, and well-being. Among the assessment tools, the most frequently used tools were Bathel Index; Functional Independence Measure, to assess activities of daily living; Short-Form Health Survey, to assess well-being, and Timed Up and Go test, to assess mobility. Conclusion : This study will help select the assessment areas and tools to be considered at discharge of stroke patients and serve a basis for the development of comprehensive assessment tools for discharge planning.

Web-accessibility evaluation tools can be used to determine whether or not a website meets accessibility guidelines. As such, many such tools have been developed for web accessibility, but most of them dynamically fetch and analyze pages and as a result, some pages maybe omitted due to the lack of access authorization or environment information. In this paper, we propose a static method that analyzes web accessibility via abstract parsing. Our abstract parsing technique understands syntactic and semantic program structures that dynamically generate web pages according to external inputs and parameters. The static method performs its analysis without omitting any pages because it covers all execution paths. We performed an experiment with a PHP-based website to demonstrate how our tool discovers more accessibility errors than a dynamic page accessibility analysis tool.

2015 개정 교육과정에서 컴퓨팅 사고력의 함양을 강조하고 있지만 컴퓨팅 사고력을 평가하기 위한 도구에 대한 개발이 미흡하다. 비버 챌린지 문항은 전 세계 60여개국의 정보 교육 전문가 집단이 약 1년 동안 공동 출제 및 검토를 통해 개발되는 문항이므로 문항의 타당도가 높다고 볼 수 있다. 다만 초기의 개발 목적이 평가도구로써 사용하기 위함이 아니었기 때문에 과연 컴퓨팅 사고력의 평가 도구로 사용할 수 있는 신뢰도를 가진 문항인가를 검증하기 위해 본 연구에서는 비버 챌린지 2017 그룹 III의 문항을 대상으로 문항내 적일관성신뢰도를 통계적으로 검증하였으며 그 결과 Cronbach ${\alpha}=.784$로 신뢰도가 높게 나타났다.

흉부 X-ray 영상은 폐 질환을 진단하는 기본적인 도구로써 널리 사용되고 있다. 정확한 진단을 위해 흉부 X-ray 영상의 품질을 평가하는 과정을 거쳐야 하는데, 이 과정은 주관적인 기준에 따라 수 작업으로 이루어지기 때문에 많은 시간과 비용이 소요된다. 따라서 본 논문에서는 임상 현장에서 사용되는 흉부 X-ray 영상 화질 평가 가이드라인을 기반으로 인공음영, 포함범위, 환자자세, 흡기정도, 그리고 투과 상태의 5가지 품질 평가를 자동화하는 도구를 제안한다. 제안하는 도구는 품질 판단에 소요되는 시간과 비용을 줄여주고, 더 나아가 흉부 병변 진단을 위한 학습 모델 개발의 양질의 학습 데이터를 선별하는 전처리 과정에 활용될 수 있다.

Existing usability testing method, particularly lab-based usability testing, has been widely implemented for development of user interface. However, the method has critical disadvantages such as high cost, time and effort, unnatural testing environment, and lack of user's direct participation in information architecture. With these backgrounds, this paper aims to develop the web-based participatory tool with particular focus on card sorting. Our tool was developed for allowing user to participate in card sorting with his own computer through web. All the data generated while user is participating in the test are automatically sent to the server, which makes it very easy to collect card sorting data. Users can drag cards of interface elements directly and build the interface structure in their own from their computer-screen so that they can represent their mental models on interface structure of testing website. These functions of our tool can help designers to implement card sorting without tedious and time consuming procedures and improve the method of usability testing by reinforcing user's active participation in building an information architecture.

Preparing the 4th industrial revolution age, a diagnostic assessment management system which can collect nationwide data has been implemented and utilized for the development of the evidence-based educational policy. This study aims to develop heuristics to help to improve usability of such systems, which are utilized by primary and middle school community including teachers and students in the nationwide. To achieve the objective, previous studies related to the development of heuristics in the educational contexts as well as basic heuristics from Nielsen were reviewed, and usability problems of the web-based diagnostic-supplement system being currently utilized, as a sample system, were analyzed. Then, the first version of heuristics was developed. The developed heuristics were validated and revised through 2 rounds of the delphi methods with 15 experts. This study has an implication with preparing foundations on improving usability of such diagnostic assessment management system utilized by school community at the nationwide in educational contexts.
