사람들이 도서관에 비치된 컴퓨터를 통해 원하는 도서가 있는지 검색하는 데에는 시간이 얼마 걸리지 않지만, 그 도서의 위치를 찾는 데에는 많은 시간이 소요되는데 그 이유 중 하나는 바로 청구 기호이다. 각종 숫자와 문자로 이루어진 청구기호는 이에 익숙하지 않은 사람들에게는 암호로 보일 뿐이다. 이에 본 논문에서는 이를 해결하기 위해 사용자가 간단한 어플리케이션을 통해 원하는 도서를 쉽게 검색하고 그 위치를 어플리케이션 상에서 확인할 수 있으며 서가에 부착된 LED 를 통해 도서의 정확한 위치를 확인할 수 있는 스마트 북 파인더를 구현하였다.

This study sought to empirically verify the mediating effect of technological self-efficacy in the relationship between digital assistance and digital information utilization by disabled elderly. The analysis data for this is the 2022 Digital Information Gap Survey by National Information Society Agency(NIA) and the analysis target is disabled elderly between 65 and 69 years of age. In this study, Process macro model 4 was used to verify the relationship between digital assistance, technological self-efficacy, and digital information utilization. As a result of the analysis, first, the higher the digital assistance of the disabled elderly, the higher the utilization of digital information. Second, it was found that the more digital assistance disabled elderly receive, the higher their technological self-efficacy. Third, as a result of bootstrapping to verify the significance of the mediation effect, technological self-efficacy was found to have a full mediating effect in the impact of digital assistance on the utilization of digital information by disabled elderly. Based on the results of this study, practical implications for improving technological self-efficacy and digital information utilization capabilities of disabled elderly were presented.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.
