As the complexity of business environment increases rapidly the use advanced information technology start to affect not only the business processes of individual companies but also the fundamental nature of business and industrial ecosystem. The changes observed at the level of business and industrial ecosystem encompasses a broad range of transformation. This unit of analysis is not sufficiently dealt with by existing information system research. This research attempted to analyze the changes in business ecosystem caused by digital transformation using Social Network Analysis. We studied structural change of the Korea film industry ecosystem chronologically divided by critical events. The film industry is chosen because it is an industry very sensitive to the changes in technology and has gone through massive transformation during the last three decade by way of using modern information technology.

As movie demands become more and more diversified, it is necessary for movie related firms to segment a whole heterogeneous market into a number of small homogeneous markets in order to identify the specific needs of consumer groups. Relevant market segmentation helps them to develop valuable offer to target segments through effective marketing planning. In this article, we introduce various segmentation methods and compare their advantages and disadvantages. In particular, we analyze "2009~2010 consumer survey data of Korean Film Industry" by using Latent Class Analysis(LCA), a statistical segmentation method which identifies exclusive set of latent classes based on consumers' responses to an observed categorical and numerical variables. It is applied PROC LCA, a new SAS procedure for conducting LCA and finally get the result of 11 distinctive clusters showing unique characteristics on their buying behaviors.

The aim of this study is to analyze the distribution structure of exclusive digital muti-media broadcasting's contents. This study takes into distribution wether exclusive contents create an additional window being serviced to other media. And it investigates how the contents work in window through analysis of programming table and interview with programming editors of each DMB service company. The window effect is a same notion to the one source multi use. In the film industry, window means a movie distribution that a film can be on one after the other starting the cinema, DVD, local cable channel, and terrestrial television. The key point of this paper is how to new media, DMB, creates its additional window and changes the existing window structure.

The Korea film industry has matured and the number of movie-watching per capita has reached the highest level in the world. Since then, movie industry growth rate is decreasing and even the total sales of movies per year slightly decreased in 2018. The number of moviegoers is the first factor of sales in movie industry and also an important factor influencing additional sales. Thus it is important to predict the number of movie audiences. In this study, we predict the cumulative number of audiences of films using stacking, an ensemble method. Stacking is a kind of ensemble method that combines all the algorithms used in the prediction. We use box office data from Korea Film Council and web comment data from Daum Movie (www.movie.daum.net). This paper describes the process of collecting and preprocessing of explanatory variables and explains regression models used in stacking. Final stacking model outperforms in the prediction of test set in terms of RMSE.

서사 활동은 인류가 처한 공간과 공간에 대한 의식과 밀접한 관계가 있다. 봉준호 감독은 영화 <기생충>(2019)에서 도시 공간 배치에 대한 독특한 견해를 통해 명확한 계급 분화가 존재하는 상하 대립의 공간을 구축했을 뿐만 아니라 공간에 대한 복잡하고 자연스러운 서사를 진행하였다. 봉준호는 현실주의 기법을 사용해 각기 다른 공간에서 살아가는 사람들의 일상적인 생활환경과 충돌을 통해 자본주의 사회 계층 사이에 존재하는 차별과 화해될 수 없는 모순을 표현하였다. 본 연구는 봉준호 영화 <기생충>의 공간 서사에 주목하고 이를 토대로 인물 사이의 관계와 사회 계급 관계에 대한 고찰을 통해 봉준호 감독의 공간 서사 의식과 영화 창작 스타일을 탐구하고자 한다. 공간은 영화 서사의 중요 요소이고 또한 영화 <기생충>에서도 많은 비중을 차지하고 있으며, 공간은 이 영화의 서사 전개를 위한 기초가 된다. 영화의 공간 서사는 물리적 공간에 한정되지 않고, 인물과 사회 사이의 관계를 밝히는 은유적 의미를 지니고 있다. 또한 해당 영화는 유형 영화일 뿐만 아니라 시대 발전 과정에서 사회 계층의 모습에 대한 기록 역할도 담당한다. 전체 영화는 사상성과 예술성이 적절히 결합되었고, 관객들은 이 영화를 통해 일정한 공감을 얻을 수 있으며, 또한 사회의 상황에 대해 깊이 생각하게 만들었다.

This paper discusses the technical exploration of Ang Lee's cinematic works and the unique visual beauty he presents. Ang Lee has successfully tackled various themes and genres, creating films that harmoniously blend Eastern and Western cultural sensibilities. These films are technologically innovative and show the interaction between technology and art, industry and culture. Therefore, this paper analyses the correlation between film technology and visual beauty in Ang Lee's works, and explores the discourse on how the relationship between film technology and art has changed with the development of film. Furthermore, this paper aims to provide insights into how technological innovation can enhance artistic creativity. The contribution of this study lies in the in-depth exploration of the relationship between film technology and art, with a focus on technological innovation and the visual beauty in Ang Lee's works. The research findings reveal that Ang Lee's films showcase the application of advanced technologies, captivating audiences with their unique visual aesthetics. The utilization of emerging technologies enables his films to possess not only visual impact but also convey profound emotions and themes. We conclude that technological innovation in film not only provides artists with more creative tools and expressive techniques but also, when combined with artistic sensibilities, creates captivating and visually expressive cinematic works. This discovery offers a new perspective for film production and opens up greater possibilities for collaboration between artists and technology experts.

영화 <기생충>은 한 가족의 삶을 부유한 가족에 기생하여 사는 기이한 삶의 방식으로 접근하고 있는 특이한 영화로 우리 사회의 빈부의 격차가 얼마나 큰지를 보여주는 암울하고 처절한 의미를 담고 있다. 따라서 본 연구는 이러한 영화 <기생충>에 들어 있는 집과 가족의 의미와 사회적 함의가 무엇인지 짚어 보고자 한 것이다. 그 결과 영화 <기생충>에 들어 있는 세 가족(기택네 집, 박 사장집, 가정부의 공간)의 집은 확실한 계층을 의미하며 그 집에 살고 있는 가족의 위치나 계급을 상징적으로 나타내고 있다. 그리고 이들 3가족에게 나타난 가족의 의미는 기생하듯 살고 있는 하층 계급은 가족끼리 상호조력의 개념은 가지고 있으나 양심이나 도덕개념은 없다. 또한 이 영화 <기생충>에 들어 있는 사회적 함의를 짚어 보면 빈부의 격차에 따른 계층의 의미와 영화에서 상징하는 수석의 의미, 그리고 비극적 결말로 볼 수 있다. 우리는 이 영화의 결말을 통해 빈부의 격차가 극심한 사회적 불균형에서 오는 우리의 미래를 예견해 볼 수 있다.

홍콩영화<무쌍>은 위조지폐 제작과정, 스릴있는 총격전, 폭파장면을 기반으로 한 복잡한 스토리 전개와 예상 밖의 반전 결말, 그리고 월드스타 주윤발의 개성 등 다양한 요소로 영화 흥행에 성공시켰다. 영화의 전개과정에서, 감독은 사건의 전개자인 이문을 이용해 시각을 한정시켜 경찰과 관중을 속임수에 빠지도록 이끌었고, 배우 주윤발의 상징성을 통해 관객들에게 "화가"로서의 이미지를 부각시켰으며, 각기 다른 인물과 장소의 복합적인 서술과 플래시백을 도입함으로써 복선층의 전개구조로 진상을 층층이 밝혀내었다. 영화에서 3번의 대반전이 나타나는데, 반전 때마다 영화의 전개가 완전히 뒤집혔고, 또 뒤집힌 전개가 앞 스토리와 어떠한 관련이 있는지 관객이 알아채지 못하도록 하였다. 이 때문에 충만한 긴장감을 불러일으켜 관객들로 하여금 공감대를 형성하였고, 진실을 가려내는 심리게임 과정을 통해 완벽한 해방감과 해탈감을 느끼도록 하였다.

Compared to sintered polycrystalline diamond (PCD), the deposited thin film diamond has a great advantage on the fabrication of cutting tools with complex geometries such as drills. Because of high performance in high speed machining non-ferrous difficult-to-cut materials in the field of automobiles industry, aeronautics and astronautics industry, diamond-coated drills find large potentialities in commercial applications. However, the poor adhesion of the diamond film on the substrate and high surface roughness of the drill flute adversely affect the tool lift and machining quality and they become the main technical barriers for the successful development and commercialization of diamond-coated drills. In this paper, diamond thin films were deposited on the commercial WC-Co based drills by the electron aided hot filament chemical vapor deposition (EACVD). A new multiple coating technology based on changing gas pressure in different process stages was developed. The large triangular faceted diamond grains may have great contribution to the adhesive strength between the film and the substrate, and the overlapping ball like blocks consisted of nanometer sized diamond crystals may contribute much to the very low roughness of diamond film. Adhesive strength and quality of diamond film were evaluated by scanning electron microscope (SEM), atomic force microscope (AFM), Raman spectrum and drilling experiments. The ring-block tribological experiments were also conducted and the results revealed that the friction coefficient increased with the surface roughness of the diamond film. From a practical viewpoint, the cutting performances of diamond-coated drills were studied by drilling the SiC particles reinforced aluminum-matrix composite. The good adhesive strength and low surface roughness of flute were proved to be beneficial to the good chip evacuation and the decrease of thrust and consequently led to a prolonged tool lift and an improved machining quality. The wear mechanism of diamond-coated drills is the abrasive mechanical attrition.
