우리나라의 사교육기관인 학원의 수가 증가하고 그에 따른 학생들의 수도 증가함에 따라 관리자측면에서 학생관리 시스템의 변화가 제기되고 있고 특히 학생들의 등하교에 따른 출결여부와 학부모에게 공지사항을 전달하는데 많은 시간적, 경제적 비용이 소모되고 있는 실정이다. 이러한 문제를 해결하기 위하여 본 논문에서는 최적화된 RFID기술에 관해 연구하였다. RFID리더기를 이용하여 학생들의 출결여부를 실시간으로 입력함으로써 학생 관리를 하는데 있어서 시간과 노력을 줄일 수 있는 RFID기술 기반의 학원관리 시스템을 구현하였다. 실시간으로 SMS메시지 전송서비스를 제공하였으며, Tag를 인식 할 때 해쉬기반의 인증 메커니즘을 추가하여 구성하였다.

The purpose of this study is to examine the importance and satisfaction of users in the use and selection of a dance academy and contribute to methods for the activation of a dance academy based on basic information. A questionnaire survey was conducted with 213 users attending 12 dance academies in G Metropolitan City using the IPA statistical method. The following conclusions were drawn. The highest importance of a dance academy in IPA analysis was a professional teacher, followed by clean dance equipment, transit accessibility, dance academy fee, and a kind teacher. The highest satisfaction was a professional teacher, followed by various dance programs, teacher's choreography ability, a kind teacher, and transit accessibility. Based on the findings, dance academy users felt that the professionalism and kindness of teachers who directly teach them, academy fee, and equipment cleanliness associated with the age of COVID-19 were important. High satisfaction factors were teacher-related factors and transit accessibility. Therefore, it is considered that a professional and kind teacher and clean and hygienic environment will contribute to the activation of a dance academy.

This study was conducted for the purpose of efficient radioactive waste disposal and management. Experiment was evaluated the decontamination efficiencies of the four types decontamination materials(Water, Alcohol, Decontamination Water, Decontamination Gel) with radioactive wastes generated during radio-pharmaceutical production process at Korea Institute Radiological and Medical Sciences(KIRAMS). The radioactive waste sample used in experiment is a lead plate of the fume hood that was disposed in April, 2019. In the experimental method, radioactive waste was measured before and after decontamination using a HPGe semiconductor detector and Gamma survey meter. The measured values before and after decontamination were evaluated for decontamination efficiency as a percentage. As a result, it was confirmed that a lot of specific activity and surface dose rate was removed from the radioactive wastes. In particular, when decontamination water was used, most of the radioactivity of radioactive wastes was removed. Considering these results, if decontamination water is used in decontamination of radioactive waste, decontamination efficiency equivalent to the disposition criteria can be expected with just one decontamination treatment. In addition, in the case of water and alcohol, only on decontamination was effective in approximately 75% and 95%. Otherwise, when decontamination gel was used, it was confirmed that the largest deviation occurred among all experimental results.
