In this paper, this app is an online learning tool web application that helps learners learn efficiently. It discusses how learners can improve their learning efficiency in these three aspects: retrieval practice, systematization, metacognition. Through this web service, learners can proceed with learning with a flash card-based retrieval practice. In this case, a method of managing a flash card in a form similar to a directory-file system using a composite pattern is described. Learners can systematically organize their knowledge by converting flash cards into a mind map. The color of the mind map varies according to the learner's learning progress, and learners can easily recognize what they know and what they do not know through color. In this case, it is proposed to build a deep learning model to improve the accuracy of an algorithm for determining and predicting learning progress.

2020년의 경우 6월부터 8월 중순까지 54일 동안 전국에 걸쳐 대규모 폭우가 집중적으로 내리면서 산사태·침수·저수지 붕괴 등이 산발적으로 발생하였다. 특히 집중호우와 같은 풍수해의 경우 매년 반복적으로 발생하는 재난유형으로서 안전점검과 같은 대비를 위한 활동을 실시하고 있음에도 피해가 꾸준히 발생하고 있는 실정이다. 재난으로 인한 반복적인 피해로 인해 국가의 재난대응에 관한 관심이 점차 증가하고 있다. 현재 이러한 재난대응을 위하여 재난유형별로 위기관리 매뉴얼을 구축하였으며, 13개 협업기능을 통해 효율적인 재난대응을 실시하고자 정부 및 각 지자체, 유관기관 등이 노력하고 있는 실정이다. 그러나 복합적이고 큰 규모의 재난이 발생하면 현장과 상황실 간에 정보공유가 제대로 이루어지지 않는다는 문제가 반복적으로 발생하고 있다. 재난이 발생하면 지자체에서 재난대응 및 상황관리를 우선적으로 실시하고 있으나 재난현장에 파견한 현장담당자의 경우 잦은 보직이동으로 재난현장에서 필요로 하는 정보와 전달해야하는 필수정보에 대해 정확히 알지 못해 재난현장에서 수집해야할 정보들을 제대로 파악하지 못하는 등 재난대응에 있어 어려움을 겪기도 한다. 또한 현장대응 담당자들이 초기 대응에 집중 할 수 있는 정보전달 체계가 존재하지 않아 상황실에서 재난현장으로 필요로 하는 정보를 전송하는 현장대응 지원체계가 미비한 상황이다. 이에 본 연구에서는 재난현장과 상황실 간 원활한 소통뿐 만 아니라 재난현장담당자들이 재난현장 및 피해현황 정보 등을 신속하게 수집할 수 있도록 재난현장에서 필수적으로 수집되어야하는 정보 DB(Database)를 설계하였으며, 이를 바탕으로 모바일 기반 재난현장 정보수집 앱을 개발하여 현장대응 지원체계의 기초를 제시하고자 하였다.

The mammalian sirtuin family, consisting of SIRT1-SIRT7, plays a vital role in various biological processes, including cancer, diabetes, neurodegeneration, cardiovascular disease, cellular metabolism, and cellular homeostasis maintenance. Due to their involvement in these biological processes, modulating sirtuin activity seems promising to impact immuneand aging-related diseases, as well as cancer pathways. However, more understanding is required regarding the safety and efficacy of sirtuin-targeted therapies due to the complex regulatory mechanisms that govern their activity, particularly in the context of multiple targets. In this study, the interaction landscape of the sirtuin family was analyzed using a systems biology approach. A sirtuin protein-protein interaction network was built using the Cytoscape platform and analyzed using the NetworkAnalyzer and stringApp plugins. The result revealed the sirtuin family's association with numerous proteins that play diverse roles, suggesting a complex interplay between sirtuins and other proteins. Based on network topological and functional analysis, SIRT1 was identified as the most prominent among sirtuin family members, demonstrating that 25 of its protein partners are involved in cancer, 22 in innate immune response, and 29 in aging, with some being linked to a combination of two or more pathways. This study lays the foundation for the development of novel therapies that can target sirtuins with precision and efficacy. By illustrating the various interactions among the proteins in the sirtuin family, we have revealed the multifaceted roles of SIRT1 and provided a framework for their possible roles to be precisely understood, manipulated, and translated into therapeutics in the future.

This study aimed to examine the current status of mobile applications for garden design and extract valuable contents for the development of garden design programs for future reference. Mobile applications released in Korean or English on Google Play App Market as of July, 2018 were analyzed in this study (1 application in Korea and 14 applications overseas). The purposes of this study are to analyze the components of the programs for those who actually intend to create a garden and to use it as a resource for developing mobile applications for garden design. Thus, program components and contents were analyzed for garden design applications based on real space (1 application in Korea and 3 applications overseas) that could actually help users. The analysis of mobile applications for garden design shows that while overseas garden programs are rapidly developing in various fields, the number of garden design mobile applications developed in Korea and the amount of information platforms are significantly insufficient. This study suggested flowchart for garden design mobile applications based on the analysis results of existing garden design application. This flowchart includes a series of processes from planning/designing gardens to purchasing plants and facilities to constructing/maintaining gardens for users who intend to design and create a real garden. Furthermore, this study proposed a freemium business model based on 4R(Reflex, Reality, Real place, Real communication) marketing strategies for mobile applications. Realistic experiences can be increased through graphics and information about gardens and plants provided in this study, and location-based information services as well as the creation of systems connected with vendors and suppliers of products related to gardens can induce consumers' purchasing behaviors. Additionally PR activities through various garden-related cultural events are expected to attract more users.
