Identifying and searching for characters appearing in scenes during multimedia video editing is an arduous and time-consuming process. Applying artificial intelligence to labor-intensive media editing tasks can greatly reduce media production time, improving the creative process efficiency. In this paper, a method is proposed which combines existing artificial intelligence based techniques to automate character recognition and search tasks for video editing. Object detection, face detection, and pose estimation are used for character localization and face recognition and color space analysis are used to extract unique representation information.

While dramatic shifts in the media environment underscore the emerging importance of structural approaches in media studies. political economists in Korea have failed to meet such demands. It is particularly noteworthy that their most serious weakness lies in economic theories. This paper aims to examine major problems in political economic approaches in Korea and suggest some research agenda and directions for the future. Above all, political economists need to scrutinize and elaborate both microscopic and macroscopic frameworks. On the microscopic level, they may learn tremendous implications from the "audience-commodity" thesis and recent debates on "information goods" among Korean economists. For the more macroscopic part, it is urgently needed to delve into mid-level issues that may illuminate specific ways the media capital operates: trends in the accumulation of capital, the influence of technological innovation, changes in the labor process, and the relations among production, circulation and consumption sectors.

피혁 제품의 품질을 결정함에 있어 가장 중요한 부분은 눈에 보이는 표면상태이다. 지금까지 피혁제조업체에서 대부분의 피혁을 육안으로 선별하여 오고 있는데, 이러한 방법은 등급을 구분하는데 있어 일관성이 부족할 뿐만 아니라, 많은 노동력과 시간이 소모되고 또한 미세한 결함이나 정밀한 치수를 감지할 수가 없어, 등급의 품질에 많은 문제점을 가지고 있다. 이러한 문제를 해결하고자 본 논문에서는 실시간 영상처리와 A. I를 접목하여 피혁 자동 등급 선별 시스템을 제안하고자 한다. 우선 피혁 자동 등급 선별 시스템에서 가장 중요한 실시간 영상처리를 이용하여 A. I에 적용될 수 있는 벡터의 추출 및 판정결과를 제시하여 본 논문의 정확성을 확인하고자 한다. 피혁 시스템의 설계는 세계 피혁업계와 차별을 기하고 검사시간을 단축하여 생산 효율성을 증대하며, 등급의 표준화 및 품질의 고급화를 도모할 수 있다.

This study used data from the 6rd and 12th year of the Korean Welfare Panel to evaluate the effects of the Personal Assistance Service(PAS) system on the labor market of PAS users' participation. For the purpose of this study, 64 program groups using the Korean PAS and 344 control groups not using the Korean PAS were selected using Caliper matching among the propensity score matching. A chi-square test was used for the difference in characteristics between groups, and a simple difference-in-differences (DID) model and a double-difference multiple regression analysis of DID were performed to estimate the effect of thepolicy before and after the Korean PAS. As a result of the study, it was found that statistically, PAS had no significant effect on the labor market. This is due to the low number of system users, resulting in low post-hoc power, incomplete matching and limited availability of PAS Assistants for Disabled People. Therefore, In order to demonstrate the effectiveness of the Personal Assistance Service(PAS) system, specialized services and systems that meet the needs of the disabled and household members should be implemented.

As life, once immersed in labor, changes with values and lifestyles, individuals consume or participate in culture and arts for learning, meeting of intellectual needs, pleasure, and exchange. As culture and art spaces have increased in recent times, these spaces have been transformed into places to create, view and exchange culture and art, and to consume cultural goods. Culture and art spaces have created and developed new genres and technologies that give viewers the opportunity to communicate and participate, allowing them to understand and accumulate works of media. A media façade thus gives a preference to places for visitors by giving an impression over a short period of time in culture and art spaces that are not areas for exhibitions and performances, and providing an opportunity to more easily approach and understand works and culture and art spaces. A media façade is a type of medium that imparts aesthetics and information by installing LED lighting on the exterior wall of a building for the realization of media functions. In order to analyze the effect of the media façade on preferences for culture and art spaces, a research model was established with media façade characteristics as independent variables and preferences for culture and art spaces as dependent variables. As a result, media façade design and media features influenced satisfaction, while the media characteristics of the media façade influenced recommendation and revisiting, suggesting that many changes will take place in culture and art spaces.

Dataset is getting more import to develop a learning based algorithm. Quality of the algorithm definitely depends on dataset. So we introduce new dataset over 200 thousands images which are fully labeled multi modal sensor data. Proposed dataset was designed and constructed for researchers who want to develop detection, tracking, and action classification in outdoor environment for surveillance scenarios. The dataset includes various images and multi modal sensor data under different weather and lighting condition. Therefor, we hope it will be very helpful to develop more robust algorithm for systems equipped with difference kinds of sensors in outdoor application. Case studies with the proposed dataset are also discussed in this paper.
