In games and films, the most highlighted fields in entertainment industry, those special effects such as flame, explosion, smoke, liquid, snow, rain and dust are generated through the particle system. Special effects can be expressed realistically by the particle system API that is a graphic library of high level in game and virtual reality. When developers apply the particle system API in applications, they must exchange parameters repeatedly and compile source codes until special efforts that they want are expressed, and It takes much time until the minute control that have relations between each parameters. This paper develops a particle system API usable in on-line game and real-time virtual reality and presents particle system editor that can see and create special effect easily through attributes adjustment such as position, velocity, color, transparency, size, age, the secondary position, the second velocity etc.

VR(Virtual Reality), which has drawn attention as a major area in ICT, is currently being used in various fields, including medical care, movies and architecture. Although VR technology is used in various fields, contents are mainly developed by creators where needs of users are easily left out of consideration leading to failure in forming a consensus between UI(User Interface) and UX(user experience). To identify the consumer preference and attribute level of VR game content, which is responsible for the largest proportion of VR contents, this study was designed to examine the consumers' preference properties of VR game contents through a Conjoint Analysis and derive the relative importance and weightings of each group. The study collected 166 questionnaires over a total of three months from May to July 2019, 150 of which were completed (90.4%). Statistic analysis was conducted using SPSS Ver. 25.0. The results of the study showed that the genre of the game (42.6%), number of players (24.0%), price for payment (20.3%) and game planning (13.1%) were important attributes in choosing VR games. The optimal mix of attributes was derived with new games, RPGs, multi-play and medium price (22,000 KRW). Before mentioning technology in the expectations of users who use VR game content, which is the most preferred among VR contents, this study recognized the need to have a fun and new experience through VR game content. Therefore, it is expected that this will serve as a reference for consumer behavior of VR game contents and research on VR game contents development.

Promotion and marketing, which are essential to lower the investment risk and maximize commercial profit in the video game market. Game developers and publishers set up public relations strategies to encourage potential consumers' needs. Considering characteristics of video game, the trailer, which is the animated image advertisement material, could occupy a key position in its promotion and marketing plan. Cinematic spectacles and attractive narratives are essential ingredients for game trailers, which are usually produced in 3D animation. Dead Island is an open world first person shooters (FPS) game released in 2011. When launched, it grabbed a great attention with a trailer, awarded the Golden Lion Prize for the best internet film at the Cannes Lions International Festival of Creativity. The game was a commercial success and several spin-offs were producted. In 2014, its publisher, Deep Silver showed the official trailer of Dead Island 2 at Electronic Entertainment Expo, the world's largest game show. Dead Island 2 was scheduled to be released in 2016, but has been now delayed until 2018. This study compares and analyzes two trailers of Dead Island 1 and Dead Island 2. We examine the narrative structure of the trailer for the sequel promotion of a successful game. The differences between the two could be useful for building a promotion strategy of other game series.

Nowadays, 3-D(Three-dimensions) is used in various field such as Games, Movies, Animations etc. Especially the Role of 3-D computer graphic is being generalized by turnover of Screen from '2-dimensional' to '3-dimensional'. There are not enough data about 'Motion Capture' even though it plays main function in 3-dimensional movement. 'Motion Capture' could be also unfamiliar for people. And as a matter of fact, the use of this equipment is limited due to its high cost. Therefore, I studied the outline of Digital Motion Capture system and its application to 3-D game Character Animation. And I checked the movement of 3-D Character after transplanting the Motion Data to the 3-D Character. I acquired Motion Data by Optical Motion Capture Equipment which we possess and transplanted it into the 3-D Character then Implemented it as walking, running and hitting which are the basic motions of Expression.

The screen quota system is one of the most controversial issues in the Korean film industry. There are two different points of view regarding the system. Some say it is highly effective to protect and nurture Korean movies. However, others argue that it hurts the duality of the Korean movies. The number of days, for which Korean movies have to play on local screens, has been reduced to 73, starting on July 1st, 2006. Actually, it is 50 percent fewer than the previous year. In facL Korea has implemented the screen quota. system two times. First, it was practiced from 1935 to 1945, during the Japanese colonial period. This was to regulate imported movies, especially American ones, as the Japanese government was to use movies for the political propaganda. In 1935, the number of foreign movies screened had to be less than three fourths of the total. And they gradually reduced the size by two thirds in 1936, and again by half in 1937. After the attack on Pearl Harbor when the Pacific War happened, Japan completely banned importing American movies in Korea. The reason why it regulated the imported foreign films is to increase the number of domestic movies, both Japanese and Korean. It was for making propaganda films fur carrying the war. The second practice of the screen quota is from 1967 to the present year. It was designed to boom the Korean film industry. However, the competitive power of Korean films has not been improved in spite of the practice of the system. Moreover, the film industry has gone through the depression. Korean film agencies have occupied the Korean film market thanks to the protection by government. The founding of the film agencies has been strongly regulated. So has importing foreign movies. Under the special protection like this, Korean film agencies have been enjoying the monopoly In the mean time, they have pursued income not by making quality movies but by importing foreign movies. As a result, cinema audiences turn away form Korean films and prefer foreign movies. Furthermore, the screen quota system hurts the relationship between film producers and distributors, imposing the duties only on theaters. In short, the screen quota system has satisfied neither film producers, theater runners, nor film goers. In other words. the excessive protection has weakened the competitive power of Korean film industry.

본 연구에서는 영화나 게임 등에서 사용되는 인간형 관절체의 움직임을 만들어내기 위하여 동역학 시뮬레이션을 이용하는 방법을 제안한다. 동역학을 이용하여 동작을 생성하는 방법은 실제 배우가 연기하기 힘들어서 동작 포착을 활용할 수 없는 경우, 키프레임 방식에 비해 보다 사실적이고 효과적으로 동작을 만들어 내는 장점이 있다. 하지만 시간이 많이 소요되고 결과 동작을 예측하거나 제어하기 힘들기 때문에 지금까지 활용도가 낮았다. 본 연구에서 제안하는 방법은 복잡한 최적화나 컨트롤러 모델링과정 없이 동작 포착 데이터를 이용한 비례 미분 제어기를 통해서 포착된 동작과 유사한 패턴을 가지는 관절 제어기를 만들어낸다. 특히, 내부 관절 제어기뿐만 아니라 최상위 관절에 작용하는 가장제어기를 생성하여 포착된 동작의 관절 궤적을 보다 효과적으로 흉내 낼 수 있게 한다. 생성된 제어기의 매개변수를 조정함으로써 여러 가지 효과를 만들어 낼 수 있으며, 동시에 다양한 동작 패턴도 적용 가능하다. 마지막으로 제어기를 통해 시뮬레이션 되는 동작과 원래 동작 포착된 결과를 혼합하거나 보간함으로써 최종 동작을 생성한다.

디지털콘텐츠 산업분류체계를 비롯한 기존 방식으로는 현재의 디지털콘텐츠를 통찰력 있게 보기 힘듭니다. 이는 디지털콘텐츠 일반에 대한 인식의 틀이 부실한 탓입니다. 넓은 의미의 텍스트에서, 시점(視點)은 인식의 틀입니다. 문학과 미술, 영화와 관련된 콘텐츠 하부영역에서는 시점 연구가 체계적으로 이루어져 왔습니다. 이러한 시점 연구결과들을 통합하고 정리하여 디지털콘텐츠에 접목시켰습니다. 연구자는 콘텐츠와 그것의 사용자에 대한 관계를 두가지 기준으로 구분하였습니다. 하나는 콘텐츠와 사용자 자아인 페르소나 사이에 성립되는 '맥락인지적시점(ContextualView)'이고 나머지 하나는 콘텐츠를 비추는 눈인 '시각적시점(CameraView)'입니다. 맥락인지적시점은다시 '인물', '상대', '관객'으로 구분하였고 시각적시점은 '일인칭', '이인칭', '삼인칭'으로구분하였습니다. 그리고 이를 씨실과 날실로 연결하여 'CCmatrix'라 하였습니다. 그리고 월드 오브워크래프트를 'CCmatrix'로 분석하고 캐릭터 수준별로 일정한 패턴을 발견하였습니다. 또 다른 활용으로는 디지털콘텐츠의 시점역사를 정리하고 활용가능성을 보였습니다.
