Andre Bazin called the movie frame as "the window open to the world." This expression is close to realization through 3D films. The 'Avatar' released in 2009 was a new turning point for 3D films. Nowadays the theory and information about 3D films is overflowed. It is necessary to find practices and to accumulate data useful in production of 3D films. There are several ways of working to achieve high quality 3D films. In any way that's chosen, there are priorities to be considered to create well-balanced 3D films. The aim of this article is to review primary considerations in film-making and share the technical issues experienced during the production of "Let's go to the amusement park again, Mom." Because the current practical knowledge in making 3D film is shallow, this article will offer a possible reference for further research.

The authoring systems for digital contents using multimedia technologies ate requested in many fields such as education, medical science, entertainment market e-commerce and etc. Especially, the emergence of cyber universities and the rapid expansion of on-line education market require the effective contents authoring systems, which have various functions to generate the qualified contents. Therefore, many systems arc developed and currently used. However, since the developed systems considered only the developer's convenience, the generated digital contents by using these systems are failed to draw tile users'(or learners') active interaction with contents. That is, since the users just watch the contents like watching a drama or a film, it causes many problems in delivering the contents effectively or in evaluating the users. This paper presents, develops, and implements the new contents authoring system by using programing languages and/or software tools. The presented, developed, and implemented system mimics the face-to-face education in off-line system, induces the users' active interaction with contents, and continuous evaluation to the users.

디지털 기술의 발달로 콘텐츠 서비스 방식에 대한 융복합화 현상이 두드러진다. 플랫폼, 네트워크, 디바이스 등의 발달과 함께 이루어지는 서비스 방식의 다양화는 콘텐츠 제작 및 소비에 있어 사용자의 참여를 가속화시킨다. 최근 들어 동영상 콘텐츠에 양방향성의 특징을 반영하는 서비스가 주목받고 있으며, 이에 따라 양방향 동영상의 확장된 비즈니스 모델을 고려한 신규 서비스 운용 모델이 요구된다. 이에 본 논문은 전자상거래를 지원하기 위한 기본 비즈니스 모델인 Imprimatur Business Model을 기반으로 양방향성이 반영된 동영상 비즈니스 모델을 재정의하고 그 운용에 필요한 구성 요소를 도출하였다. 서비스 운용 모델은 생성, 처리, 소비의 단계를 갖는다. 각 단계별로 세부 운용 요소를 설계하여 운용 시스템과의 연결성을 고려하였다. 이는 XML 다이어그램으로 표현되었으며 디지털 아이템의 생성, 처리, 소비에 필요한 기능을 제어하고 처리할 수 있도록 하기 위해 각 단계별 생성자(creator)와 핸들러(handler)를 정의하였다.

컴퓨터 기술의 발달로 인하여 현재 각광받는 산업인 3D 콘텐츠의 제작에 사용되는 다양한 툴이 많은 발전을 거듭하고 있다. 최근에는 영화나 애니메이션에 3D 콘텐츠가 많이 사용되면서 실제 사람이나 동물의 움직임과 똑같은 움직임을 구현하는데 많은 노력을 기울이고 있다. 동물이나 인간의 움직임은 3D로 구현하기 위해 참고할 수 있는 자료들이 많이 존재하지만 그에 비해 물고기는 참고자료가 많이 부족하고 이를 토대로 그 유연한 움직임을 구현하는 것이 쉽지 않다. 본 논문에서는 물고기를 Polygon방식을 이용하여 모델링하고 뼈를 심는 과정인 리깅과정을 통해 최종적으로는 물고기의 움직임을 단순화시켜 자연스러운 애니메이션을 쉽게 구현할 수 있는 방법을 제시하고 이것을 활용할 수 있는 방안을 제안한다.

Facial expression is an important means of representing characteristics in movies and animations, and facial capture technology can support the production of facial animation for 3D characters more quickly and effectively. Blendshape techniques are the most widely used methods for producing high-quality 3D face animations, but traditional blendshape often takes a long time to produce. Therefore, the purpose of this study is to achieve results that are not far behind the effectiveness of traditional production to reduce the production period of blend shape. In this paper, in order to make a blend shape, the method of using the cross-model to convey the blend shape is compared with the traditional method of making the blend shape, and the validity of the new method is verified. This study used kit boy developed by Unreal Engine as an experiment target conducted a facial capture test using two blend shape production techniques, and compared and analyzed the facial effects linked to blend shape.

The purpose of this study is to analyze how China, which is the largest consumption area of Hallyu broadcasting contents but the most illegal copy market infringe the rights of domestic broadcasters and what of the policy of regulatory authority in this illegal market. To this end, this study investigate the most common types of paths and methods of copyright infringement in the Internet and mobile multi-platform environments, and investigated how broadcasters responded to them with in-depth interviews. As a result of research, the most frequent type of infringement of rights of reproduction were to use links with web and apps and TV pads. In this regard, it was not easy to solve the problem of illegal copy in China in the way that domestic companies responded to individually, and it was very rare that the lawsuit was filed. In the future, the government will need to provide side support for Korean Wave broadcasting contents through steady monitoring as well as market research for eradication of illegal copy.

The human knowledge has been integrated mainly through the text documents. The computer technologies changed the way of production and deliverly of the documents from analog to digital. During the paradigm shift, a serious problem must occur due to a large gap between the old contents and newly generated contents. This paper reviews some methods to reduce the gap for the text document image contents.

As increasing interests for cultural content, 3D restoration about the valuable traditional architectures is in progress, nowadays. Digital restoration is generally performed with using new IT technology and equipments such as 3D scanner. From the view points of making better use of the 3D data, the methodology for 3D restoration leaves much room for improvement. When using 3D scanner, it is possible to get precise 3D data for exterior of the building but huge data size and insufficient information for the wooden intra structure might be obstacles for using them as a source of various digital contents. In traditional wooden structure, the binding rules for corresponding architectural components are important factor for realizing the architectural culture at that times. In this paper, we develop a design tool and architectural components reflecting the wooden intra structure. Moreover, we propose a new 3D restoration method from the design tool, which is good for making contents offering useful information for processes of construction and binding rule in a real time just at a glance.

Today, home gardening is in the spotlight. Therefore, the necessity of developing a new type of gardening product was raised according to the consumer's desires. This study, the contents were developed using sparrows, a helper who helped the bean rat's grain-cracking task among the characters of 'kongjwi patjwi'. The cultural contents convergence product is a lid production that is used at the end of the plant support. The fabrication method was designed using UG NX program after design research, and after printing by 3D polyjet method, mold was made and cast into silicon and resin. Through product manufacturing, we could confirm the public's interest in the possibility of new products and creativity. In the future, it is expected that the development of products incorporating cultural contents through various cultural archetypes will be activated, contributing to the enhancement of economic added value and national brand value.

In addition to the OTT video production service represented by Nexflix and YouTube, a personalized recommendation system for content with artificial intelligence has become common. YouTube's personalized recommendation service system consists of two neural networks, one neural network consisting of a recommendation candidate generation model and the other consisting of a ranking network. Netflix's video recommendation system consists of two data classification systems, divided into content-based filtering and collaborative filtering. As the online platform-led content production is activated by the Corona Pandemic, the field of virtual influencers using artificial intelligence is emerging. Virtual influencers are produced with GAN (Generative Adversarial Networks) artificial intelligence, and are unsupervised learning algorithms in which two opposing systems compete with each other. This study also researched the possibility of developing AI platform based on individual recommendation and virtual influencer (metabus) as a core content of OTT in the future.
