Auditory and language train for the hearing-impaired is an essential course improving conversational capability with non-deaf and accompanying the financial burden and the physical fatigue of parents or a teacher. To reduce these problems, web-based training contents have been developed. But these contents have been developed without consideration of individual difference such as various levels of residual hearing and the learning capability of hearing-impaired. Therefore, it is important that appropriate training progress for each hearing-impaired should be designed by evaluating and analyzing the personal status, residual hearing, learning capability and training achievement. This paper suggests auditory and language training service model for the hearing-impaired, which is planning and managing an auditory and learning training based on personal evaluation. In addition, this paper suggests a design method for a serious game content planing based on this service model.

최근 급격한 도시화와 기후변화로 인해 도시의 홍수피해가 증가하고 있으며, 복합적인 재난으로 악화되는 경우가 많아졌다. 복합재난으로 인한 피해를 줄이기 위해 재해발생 전·후 대응이 중요하며, 이를 위해 복원력 개념을 도입할 필요가 있다. 도시 배수 시스템의 복원력은 대상유역의 면적과 절대적인 침수량에 따라 좌우된다. 따라서 지역의 도시 배수 시스템의 복원력을 정확하게 평가하기 위해 대상유역의 정보를 반영한 지역 맞춤형 복원력 지수의 개발이 필요하다. 대상유역의 정보를 반영하기 위해 도시 배수 시스템의 배수능력을 복원력 지수에 적용하였다. 도시 배수 시스템의 배수능력을 나타내기 위해 시스템 잔류유량을 분모로, 침수량을 분자로 하여 복원력 지수를 계산하였다. 본 연구에서는 제안된 새로운 복원력 지수를 대구 비산 빗물펌프장에 적용하였다. 강우자료는 재현기간이 100년, 200년 그리고 300년 빈도의 확률강우량을 사용하였으며, 지속시간은 30분, 60분 그리고 90분으로 설정하였다. 침수량과 시스템 잔류 유량은 1분 단위로 EPA SWMM을 통해 값을 구하였다. 시스템 잔류 유량을 기반으로 하는 복원력 지수는 최소 0.995029에서 최대 0.998662로 나타났다. 본 연구에서 제안한 도시 배수 시스템 잔류 유량 기반 복원력 지수는 배수 시스템의 처리 능력을 반영한 지수라고 할 수 있으며 배수 시설의 설치, 교체 및 재건 등 수해 방재 계획 평가에 활용될 수 있다.

Recently, uncertainty in predicting available water resources is gradually increasing due to climate change and extreme weather conditions. Social interest in water management such as flood and drought prevention is also increasing, and after the unification of water management implemented in 2018, domestic water management is facing a major turning point. As part of such strengthening of water management capabilities, various studies are being conducted to utilize a hydropower dam for flood control and water supply purposes, which was mainly operated for hydroelectric power generation. However, since the dam evaluation methods developed based on a multi-purpose dam are being applied to hydropower dams, an additional evaluation approach that can consider the characteristics of hydropower dams is required. In this study, a new water supply capacity evaluation method is presented in consideration of the operational characteristics of hydropower dams in terms of water supply, and a connected reservoir simulation method is proposed to evaluate the comprehensive water supply capacity of a dam group operating in a river basin. The presented method was applied to the hydropower dams located in the Bukhan River basin, and the results of the water supply yield of individual dams and multi-reservoir systems were compared and analyzed. In the future, the role of hydropower dams for water supply during drought is expected to become more important, and this study can be used for sustainable domestic water management research using hydropower dams.

The recent change of educational evaluation puts particular emphasis on performance assessments which can appraise learning processes as well as learning results. The performance assessment is not only helpful for the improvement of teaching and learning methods, but also for making the learning activities significant to learners themselves. In this paper we propose and implement a system to support the internet-based and essay-typed performance assessment, in which student's performance can properly be evaluated. Teachers can be relieved from the burden of testing and provided with convenient methods of evaluation. We analyze the performance of the implemented system by evaluating practical usages of selected instructors and students group.
