With the development of information and communication technology, online fractional investment platforms have emerged through the convergence of online platform technology and new investment techniques for asset-backed derivatives. In this study, the concept and previous studies of the online fractional investment platform business, commercialization models and service processes, market status, and pending discussions and alternatives were presented. Recently, the Securities and Futures Commission's decision on securitization of split ownership has become an important guide to the stable business sustainability of platform operators, but academic research is needed according to the current status and case analysis. To identify specific market issues, examples of representative online fractional investment securitization platform businesses such as "MusiCow" for music copyright, "Tessa" based on art, "Kasa" for real estate, "Piece" based on real assets, and "BangCow" for Korean beef shipments were analyzed. Through the case analysis of this study, the characteristics of the business model according to the basic assets of the online fractional investment platform were compared and presented. Since most business models are judged to be securitic, they must comply with the provisions of the Capital Markets Act or be recognized as the target of innovative financial services. From a practical point of view, it is meaningful in that it presented improvement directions that online fractional securitization platform operators should consider and organized institutional considerations for investor protection.

Recently, research and development using various Artificial Intelligence (AI) technologies are being conducted in the field of education. Among the AI in Education (AIEd), conversational agents are not limited by time and space, and can learn more effectively by combining them with various AI technologies such as voice recognition and translation. This paper conducted a trend analysis on platforms that have a large number of users and used conversational agents for English learning among commercialized application. Currently commercialized educational platforms using conversational agent through trend analysis has several limitations and problems. To analyze specific problems and limitations, a comparative experiment was conducted with the latest pre-trained large-capacity dialogue model. Sensibleness and Specificity Average (SSA) human evaluation was conducted to evaluate conversational human-likeness. Based on the experiment, this paper propose the need for trained with large-capacity parameters dialogue models, educational data, and information retrieval functions for effective English conversation learning.

We consider a Direct Input Output Manufacturing System(DIOMS) which has a number of machine centers placed along a built-in Automated Storage/Retrieval System(AS/RS). The Storage/Retrieval (S/R) machine handles parts placed on pallets for the operational aspect of DIOMS and determines the optimal operating policy by combining computer simulation and genetic algorithm. The operational problem includes: input sequencing control, dispatching rule of the SIR machine, machine center-based part type selection rule, and storage assignment policy. For each operating policy, several different policies are considered based on the known research results. In this paper, using the computer simulation and genetic algorithm we suggest a method which gives the optimal configuration of operating policies within reasonable computation time.

This study analyzed the factors that viewers consider when watching anime on Over The Top(OTT) service platforms and the characteristics of each type of preference, which are the components of anime preference. To this end, the survey data of 240 animation major students were used for analysis, and the conclusions drawn through frequency analysis and cross-tabulation of IBM SPSS Statistics 27 are as follows. Netflix is the OTT service platform that viewers use the most, and TV series are the most preferred for animation works. In addition, it was found that Netflix OTT original animation works were preferred over other platforms, and long-form animation preferred Disney+. Among the characteristics of each type of animation preference, it was found that the factors considered when watching animation in terms of narrative value, aesthetic value, and entertainment value respectively value the structure, screen production, and immersion of the storyline. It is hoped that this study will be used as useful data for producing animation contents with the OTT service platform.

In order to provide theoretical guidance to research in platform strategy, we build the conceptual framework based on the organizational ecology and analyze symbiotic/competitive relationship between platform entities. Platform owner and service provider (i.e. complementors) make symbiotic relationship, where platform owner provide service provider user-base and platform resources such as marketing tools and platform technology, and service provider provide platform owner services which users utilize. In addition to symbiotic relationships, platform owner has competitive relationship with other platform owners, and service provider builds competitive relationship with other service providers. In these relationships, the strategy of platform owner affects service provider and service provider builds a strategy for their own survival and success. This type of interaction makes competitive dynamics in platform. However, previous platform literature focuses on strategies to enhance network effect from the perspective of platform owner. Thus, there is little attention on interaction among the service providers. Using the framework based on community ecology of organizational ecology, we analyze interaction and strategy between platform owner and service provider in the viewpoint of platform openness strategy and platform pricing strategy. This research contributes to the literature of platform strategy by providing a theoretical framework based on organizational ecology to deeply understand the dynamics of platform.

공간정보산업의 분석은 전통적으로 산업가치사슬 분석방법에 기초해 수행되어 왔으나 가치사슬 접근방법의 난점으로 이에 근거한 기업 전략과 정부정책의 성과가 미미한 실정이다. 최근 다양한 분야에서 전통적인 산업분석의 틀을 벗어나 기업생태계와 플랫폼의 개념을 이용해 기업 및 산업 활동을 조망하려는 시도가 활발하다. 본 연구의 목적은 동태적 혁신이론에 기반하여 생태계내 구성주체들과 플랫폼이 공진화하면서 공간정보생태계가 형성되고 발전하는 과정을 표현할 수 있는 단계적 진화 모델을 제시하는 것이다. 이를 바탕으로 공간정보생태계 조성을 위한 기업의 전략과 정부 정책 수립에 주는 시사점을 도출하였다.

딥러닝 기술의 발전으로 객체 인색, 영상 분석에 관한 성능이 비약적으로 발전하였다. 하지만 고성능 GPU 를 사용하는 컴퓨팅 환경이 아닌 제한적인 엣지 디바이스 환경에서의 영상 처리 및 딥러닝 모델의 적용을 위해서는 엣지 디바이스에서 딥러닝 모델 실행 환경 과 이에 대한 분석이 필요하다. 본 논문에서는 RISC-V ISA 를 구현한 RISC-V 가상 플랫폼에 yolov3-tiny 모델 기반 객체 인식 시스템을 소프트웨어 레벨에서 포팅하여 구현하고, 샘플 이미지에 대한 네트워크 딥러닝 연산 및 객체 인식 알고리즘을 적용하여 그 결과를 도출하여 보았다. 본 적용을 바탕으로 RISC-V 기반 임베디드 엣지 디바이스 플랫폼에서 딥러닝 네트워크 연산과 객체 인식 알고리즘의 수행에 대한 분석과 딥러닝 연산 최적화를 위한 알고리즘 연구에 활용할 수 있다.

구매 의사 결정 단계에서 이미지나 동영상의 영향력이 지속해서 증가하고 있음에도 불구하고 시각적 정보가 소비자의 구매 의사 결정 과정에 영향을 미치는 메커니즘과 이에 따른 기업, 특히, 오프라인 기업의 성과에 대해서는 아직 알려진 바가 많지 않다. 이에 본 연구는 O2O 플랫폼에 입점한 10만 개 식당의 실제 예약 매출 데이터를 분석하여 이용자와 사업자가 O2O 플랫폼에 업로드한 사진 등의 시각적 정보가 기업의 성과에 미치는 영향과 메커니즘을 이중 처리 이론 기반으로 파악하고자 한다. 또한 저장하기, 공유, 리뷰 등 고객 참여와 프랜차이즈 가맹의 시각적 정보와 성과 간 관계에 대한 조절된 매개 효과를 분석한다. 본 연구는 이중 처리 이론 기반으로 시각적 정보가 구매 의사 결정 과정에서 작동하는 메커니즘을 설명하는데 기여할 것으로 기대한다. 그뿐만 아니라 실제 예약 매출 데이터를 활용하여 분석함으로써 직접적이고, 수익적인 측면의 기업 성과를 측정할 수 있을 것이다. 또한 오프라인 소매점에서 활용할 수 있는 온라인 채널 전략에 대한 실무적인 시사점을 제공할 것으로 기대한다.

This thesis presents an emotion-based contents player platform that can change its visual and aural components as user's emotions. It analyzes the emotion as pleasant, unpleasant, aroused, and relaxed based on the physiological signals and the user's active response. Accordingly. the system reorganizes graphical and aural stimuli, such as, light, color, sound, in real-time. It can be used to develop and show the emotional contents and also be applied for the systematic analysis to find out how the components would affect the emotion. This paper describes overall the system architecture and the implementations of the sub-systems, as well as the actual contents built on top of the platform.
