The optical biosensor using electrically controlled-release system is developed for the measurement of peroxide concentration. The electrically controlled-release system is consisted of hydrogen bonding polymer complex between carboxylic and oxazoline group. The polymer complex form below pH 5.0 and dissolve instantly above pH 5.4. By applying the electric current to polymer complex containing reagent, the degradation of polymer complex surface occur and reagent of enzyme reaction is released because of change of local pH around the polymer complex. The release rate is constant at constant applied current and proportional to the applied electric current. Proposed controlled-release system model can predict the degradation velocity of polymer complex and degradation velocity is linearly proportional to the applied current. The released reagent and peroxide is flowed into enzyme immobilized reactor and react with enzyme. The measurement of peroxide is performed by measuring the fluorescence of enzyme reaction product. The biosensor has the linear analytical range of 0.025~1.0 mM with response time of about 20 minutes. The optical peroxide biosensor has good repeatability and the electrically controlled-release system can be applied to optical peroxide biosensor.

농아인들이 일반인들과 수어 통역사 없이 의사소통을 하기 위한 인공지능 수어 처리 시스템은 수어를 인식하여 자연어로 변환하는 모델과 자연어를 수어로 변환하는 모델로 구성된다. 본 논문에서는 한국어를 번역하여 한국 수어를 생성하는 트랜스포머 기반의 End To End 심층 신경망 모델을 구현한다. 자연어 텍스트 입력으로부터 한국 수어 동작 자세에 대한 좌표에 대한 시계열 데이터를 생성하는 트랜스포머 모델을 구현하였고, 시계열 좌표 데이터를 실제 아바타 동작으로 변환하는 Unity 기반의 아바타 모델을 개발하였다. 수어 생성 트랜스포머 모델을 학습시키기 위해 AI Hub 수어 데이터를 활용하였으며, 생성모델의 정확도를 기존 연구들과 비교하였다. 또한 생성된 아바타의 동작이 농아인이 이해할 수 있는 동작인지 수어 통역사를 통해 검증하였다. 학습 데이터에 따른 정확도 차이는 추가적인 연구를 통해 확인해야할 부분이지만 기존 연구대비 더 나은 성능을 보였다.

Contemporary science museums are enhancing their roles and functions reflecting social changes. In addition, exhibitsusing diverse exhibition techniques and medium are in very active application in the facilities recently built and in the projects toenhance the environments of existing facilities. In this way, the plan for exhibition environment to cope with social changes andupcoming future is being used as the display concept to be considered importantly for exhibition plan, and is also socialdemand which needs to be reflected to each exhibit generally rather than applied to certain exhibits. This research focuses onthat, accordingly, the fact that a variety of visitors are aware of display and behave in an exhibition space based on thereactions of their own sensory receptors is closely related to the plan for exhibition space. Therefore, this study aims atcomparing and analyzing the process for visitors to process information transmission of exhibition medium in terms of cognitivescience, and reasoning the influence on the organization of an exhibition program. In particular, this research aims atinterpreting the process of information transmission of exhibition medium formed in each exhibition area, suggesting themeanings implied in the distribution aspect of exhibition medium inside the exhibition area and the interpretation range, andempirically reviewing a series of preceding researches.
