  • This paper describes a new algorithm for human sensibility evaluation using two personality-group templates of electroencephalogram (EEG) signals. EEG signals of two groups arc collected in relaxed state, comfortable state and uncomfortable state. First of all, the characteristics of EEGs in relaxed state for two groups are compared. After verification of the results, an algorithm for sensibility evaluation is developed. In comparison of the characteristics for two personality-group EEG signals. there are distinct difference between the EEG patterns of the extrovert and the introvert. Upon these findings, the algorithm for human sensibility evaluation is designed. The results of the algorithm showed 90.0% of coincidence with given tasks. This seems to be compromising results for subject independent sensibility evaluation using EEG signal.

  • In the past, the results of window cleaning work have been judged subjective and complaints about cleaning results are being raised. In this study, we tried to quantify the evaluation of the cleaning result. For the quantification of the evaluation, a colorimeter was selected and the basic experiment was carried out. In addition, this study examined the use of standard dust powder for artificial production of contaminants in glasses. Further evaluation and analysis will be carried out to quantify the evaluation criteria of the cleaning results.

  • Given the lack of suitable quality evaluation standards for educational serious games (designed for both entertainment and instruction), we designed a development framework for evaluation standards of educational serious games and proceeded to develop standards in accordance with our proposed procedure. Our standards were designed to evaluate the quality of both technical and non-technical elements of educational serious game software products. We conducted a survey on the need for individual elements of the standard. Participants rated the need for each element on a five-point Likert scale. We then performed a reliability analysis of the survey results. Based on the survey results, we established a final standard for quality evaluation composed of 9 main elements and 31 sub-elements. The results of our research will contribute useful information to users as well as to the developers of educational serious games.

  • The water supply pipes are buried across wide range of areas, so it is hard to spot them using excavation and takes a large amount of expense. Thus, there is a high risk for direct research and application, accompanying many difficulties in implementation of them. Therefore, it is more economical and convenient to use indirect evaluation variables than direct evaluation of the buried pipes in assessing the degree of pipe deterioration. To assess the degree of pipe deterioration using the indirect evaluation variables, it should be done first to identify how and to what extent they affect the degree of deterioration. This study measured the evaluation variables for pipe deterioration using the pipe endoscope and analyzed the measurement results and the degree of impact on the pipes. In addition, this study attempted to evaluate the adequateness of the pipe deterioration evaluation using the indirect variables based on the analysis results. The evaluation variables measured through the pipe endoscope were the thickness of sediments, size of scale, degree of desquamation and condition of connections. For the indirect evaluation variables, the data such as the property data from GIS pipe network map as well as the material, diameter, age and pipe lining material of the pipe, road type, leakage frequency, average water velocity and water pressure using the leakage repair records was collected. Using the collected data, this study comparatively analyzed the indirect evaluation variables for the degree of pipe deterioration and the results from the pipe endoscope to choose appropriate variables for pipe deterioration evaluation and calculated the weights of the indirect variables on the degree of deterioration. The results showed that the order of the impact of indirect variables on deterioration was pipe age > pipe lining material > road type > leakage frequency > average water velocity with their weights of 0.45, 0.20, 0.15, 0.10, and 0.10, respectively. Conclusively, the results suggest that the measures of sediment thickness, scale size, degree of desquamation and condition of connections are appropriate for the evaluation of pipe deterioration and sufficient for the analysis of the impact of the indirect variables on deterioration.

  • 작업관련성 근골격계질환을 효율적으로 예방하기 위한 제일 중요한 요소는 관련위험 요인들에 대한 정확한 평가이다. 그러나 대부분의 근골격계질환 관련 위험도 평가도구들은 주관적평가의 가능성에 대한 지적을 많이 받아왔다. 본 연구에서는 이와 같은 지적에 대한 좀 더 체계적인 분석을 위하여 주요 평가도구들(OWAS, RULA, REBA)에 대한 일종의 민감도 분석을 수행하였다. 분석은 다음과 같이 크게 두 가지 관점에서 진행되었다; 1) 숙련자와 비숙련자에 의한 평가결과에 대한 비교, 2) 평가 시점에 따른 평가 결과의 일관성에 대한 비교. 본 연구의 주요 결과는 다음과 같다; 1) RULA와 REBA의 경우, 숙련자와 비숙련자 간에 평가결과의 차이는 통계적으로 유의 하였다. 반면에 OWAS의 경우에는 숙련자와 비숙련자간에 평가결과에 있어서 통계적으로 유의한 차이를 보이지 않는 것으로 나타났다, 2) 적용된 모든 평가도구들은 그 결과에 있어서 평가 시점에 따라 통계적으로 유의한 차이가 있는 것으로 나타났다. 본 연구에서는 연구 목적에 따른 1차 결과를 제시하였다. 이 결과를 토대로 하여 향 후 형식이나 내용면에 있어서 좀 더 확장된 개념의 연구의 수행을 통하여 평가도구를 사용하는데 있어서 체계적이고 실용적인 지침을 도출해 내리라고 판단된다.

  • 정보보안에서 AI 기술은 알려지지 않은 악성코드를 탐지하기 위해 사용한다. AI 기술은 높은 정확도를 보장하지만, 오탐을 필연적으로 수반하므로 AI가 예측한 결과를 해석하기 위해 XAI 도입을 고려하고 있다. 그러나, XAI는 단순한 해석결과만 제공할 뿐 그 해석을 평가하거나 검증하는 XAI 평가 연구는 부족하다. XAI 평가는 어떤 기술이 더 정확한지 안전성 확보를 위해 필수적이다. 본 논문에서는 악성코드 분야에서 AI 예측에 크게 기여한 feature로 AI 결과를 해석하고, 이러한 AI 결과해석에 대한 평가방안을 제시한다. 약 94%의 정확도를 보이는 tree 기반의 AI 모델에 두 가지 XAI 기술을 사용하여 결과해석을 진행하고, 기술 정확도 및 희소성을 분석하여 AI 결과해석을 평가한다. 실험 결과 AI 결과해석이 적절하게 산출되었음을 확인하였다. 향후, XAI 평가로 인해 XAI 도입 및 활용은 점차 증가하고, AI 신뢰성 및 투명성이 크게 향상될 것으로 예상한다.

  • Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

  • The purpose of this paper was to develop evaluation procedures for blended instruction, focusing on the courses that are currently offered in the university. This study analyzed current evaluation procedures and instruments and suggested redesign the evaluation process for blended instruction. The evaluation procedures are designed based on the combination of objective-oriented and consumer-oriented evaluation approaches. It includes three stages: front-end (screening), formative evaluation, and summative evaluation. During the front-end evaluation stage, information regarding students' technology skills and attitudes towards online instruction and classroom instruction are suggested to collect and plan the instructional strategies accordingly. The formative evaluation is conducted during the semester to collect students' opinions about the course and instructors modify their instruction based on the evaluation results. At the end of semester, summative evaluation is to be conducted to collect the data to improve the course. Evaluation questions and components for each stage are developed to collect the data such as students' perceptions of the course, the usefulness of online instructional materials, the effectiveness of blended learning strategies, and students' satisfaction with the course.
