Technology valuation is necessary for determining the feasibility of technology commercialization. However, existing methods focus only on technology evaluation, with limitation in sufficiently reflecting buyer viewpoint. In addition, it causes a gap between estimated value and market value. Therefore, this research suggests a new technology valuation method which focuses on the perspectives of buyers. Technology factors, buyer factors and market factors are first determined and their relationships are analyzed. Second, based on the relationships, profit projections are calculated using the discount cash flow method. Finally, profit projections for each year are discounted. The proposed method was applied using the ubiquitous home network system and audio service and illumination control method and results compared with the value of a technology valuation guide distributed by the Ministry of Trade, Industry and Energy. The technology valuation approach used in this research is quantitative and systematic and can be used as a decision making support tool in technology transfer, reflecting various perspectives of stakeholders.

THERP(Technique for Human Error Rate Prediction) 방법론은 원전의 확률론적 위험성 평가(PSA)시 운전원과 작업자의 정량적인 인간오류평가에 가장 널리 사용되고 있는 방법이다. HRA Handbook이라고도 불리는 이 모델은 운전원 행위를 시스템 부품의 한 요소로 가정하고 인간오류를 평가한다. 본 논문은 이 방법론을 이용하여 원전 등과 같이 위험시설물 중의 하나인 개스밸브 기지에서의 작업자 보수시 인적오류를 평가하고 기계적 오류와 함께 인적오류 의 기여도를 계산하였다. 본 눈문에서는 이 방법론이 원전, 개스밸브 기지 뿐만아니라 석유화 학 플랜트와 같은 위험시설물의 인적오류 평가에도 유연하게 사용될 수 있음을 보여주었다.

The predominant concerns of the study consist of: (1) the direct effects of social work students' evaluation toward connivers of exam-cheating on their evaluation toward connivers of corruptio ns in social welfare organizations; (2) the dual mediation effects of their concerning dysfunction of whistle-blowing and needing of protection arrangement for whistle-blowers. The notable findi ngs are as follows: First, the evaluation toward a person conniving at exam-cheating significantl y has an effect on the evaluation toward connivers committing corruptions in social welfare orga nizations($.211^{***}$). Second, the more positive evaluation for connivers of exam-cheating, the more concerning dysfunction of whistle-blowing, the less needing protection arrangement for whistle-blowers($-.191^{^{\prime}***}$). The students, concerning dysfunction of whistle-blowing more, show less neg ative evaluation toward a person, conniving at corruption in social welfare organizations($.245^{***}$). The more needing protection arrangement for whistle-blowers, the less positive evaluation regar ding whistle-blowers in the organizations($-.122^{***}$). Lastly, both mediating effects of the needing protection arrangement for whistle-blowers and concerning about dysfunction of whistle-blowing are significant so dual mediator are proved. Some practical implications are discussed based on the study's findings.

We have investigated the effect of student-generated rubrics on learning motivation and achievement in performance evaluation of computer class. We studied the related previous researches and developed the procedure for performance evaluation using student-generated rubrics. According to thc developed procedure, the performance evaluation has been carried. Students have more clear understanding of their assignments and rubrics during the negotiation process. Student generated rubric has a positive effect on learning motivation and achievement.

We developed a system which supports the functions of real-time evaluation and feedback for smart learning. The system is consisted of an application for tablet PC and smart phone and the server, and the client exchanges data with the server through wireless communication. Whereby, the proposed system enabled realtime interaction and feedback between learner and teacher or between learners. As a result, the instruction for each learner's level is available using the system, and then it could enhance the level of academic achievement and learning interest.

This paper proposes SERO note system which supports collaborative learning between teachers and learners by using the learner's internal and external environment information. The proposed system defines the learner's internal environment depending on desire for relearning assessment questions, and the learner's external environment depending on a percentage of correct answers. The purpose of educational evaluation through SERO typing of each question is reflected in collaborative learning between teachers and learners. As the results of SERO typing of each question are accumulated on DB and used, a variety of feedback chances can be offered to teachers and learners.

This paper proposes methods of evaluating and measuring accessibility of accredited certificate subscriber software which is one of crucial applications to submit personal certifications while web surfing. The presented methodology is to evaluate accessibility by using a certain assessment tool and is to normalize accessibility level into points, so that the software developers who are unfamiliar to screen readers can easily perform accessibility evaluation. The software from the major 78 organizations has went through the assessment. Those of 48 organizations, 62% out of the total, have acquired less than 70 points, implying the software of them is not accessible by the blind. The remaining 18 software got the highest point(88), are partly inaccessible by the blind that uses screen readers. This implies that the proposed methods are applicable to evaluate the accessibility of the software.

Recently, as the importance of walking in daily life has been emphasized, projects to guarantee walking rights and create a pedestrian environment are being promoted throughout the region. In previous studies, a pedestrian environment assessment was conducted using Jeonju-si road images, and an image comparison pair data set was constructed. However, data sets expressed in numbers have difficulty in generalizing the judgment criteria of pedestrian environment assessors or visually identifying the pedestrian environment preferred by pedestrians. Therefore, this study proposes a method to interpret the results of the pedestrian environment assessment through data visualization by building a web application. According to the semantic segmentation result of analyzing the walking environment components that affect pedestrian environment assessors, it was confirmed that pedestrians did not prefer environments with a lot of "earth" and "grass," and preferred environments with "signboards" and "sidewalks." The proposed study is expected to identify and analyze the results randomly selected by participants in the future pedestrian environment evaluation, and believed that more improved accuracy can be obtained by pre-processing the data purification process.
