Digital cinema based on digital master distribution increases with stereoscopic film as the center. DCI specification V1.0 announced at 2004, it considerates stereoscopic film screening. And now, the Society of Motion Picture and Television Engineers is establishing a task force to define the standards of a stereoscopic contents viewed in the home. Today, most Hollywood commercial stereoscopic film features animation using computer graphic. However, considering film making characteristic, stereoscopic digital cinema is required shooting in real world and editing, screening. This paper presents possibility of stereoscopic examination at NLE in the stereoscopic workflow. And we will propose new stereoscopic digital cinema workflow to apply the stereoscopic examination. Based on experimental results, the 3D ready television using 120Hz has some obstacles for contents editing, but most domestic stereoscopic monitor using circular polarization is possible for successful editing.

The purpose of this study is to discuss new entrants' role in a business ecosystem and to analyze growth strategies of a new entrant in the movie industry. When participants of a business ecosystem complement one another with their own unique capabilities, they can coevolve and develop the business ecosystem. Especially, new entrants armed with competitive advantages are the key success factor for improving robustness of business ecosystem. Korean movie industry is dominated by a few large enterprises and thereby threatening fair trade. In an effort to encourage new entrants in the industry, this study analyzed success factors of a film distributor, Next Entertainment World(NEW). The success factors include unique criteria in selecting scenarios, quality management, rapid decision making process, and competent management team.

This study explored the risk sharing mechanism in the US TV drama industry. The hollywood system of TV production and distribution can be understood to be the result of the efforts to reduce the uncertainty and the risk of investment. Since the 1990s, the vertical integration of major studios and networks has been one of the core strategies for risk sharing. In the strategy, the most important role of networks is to schedule new series that the affiliated studios produce. Networks also provide the new series their brand value. On the other hand, the most important role of studios in the vertical integrated environment is to provide the affiliated networks the infrastructures for production and distribution, financial management, and product management. In addition, networks keep the right on the series in the secondary markets, and attempt to increase the aggressive investment on new series on the base of the rights. However, such a risky investment can be the potential burden and risk for the networks in the future. This paper shows the importance of the reasonable risk sharing in the television drama industry to the Korean TV drama industry that has experienced the conflict between networks and independent production companies.

This study analyzed the relationship between key film and a box office record success factors based on movies released in the first quarter of 2013 in Korea. An over-fitting problem can happen if there are too many explanatory variables inserted to regression model; in addition, there is a risk that the estimator is instable when there is multi-collinearity among the explanatory variables. For this reason, optimal variable selection based on high explanatory variables in box-office performance is of importance. Among the numerous ways to select variables, LASSO estimation applied by a generalized linear model has the smallest prediction error that can efficiently and quickly find variables with the highest explanatory power to box-office performance in order.

본 연구는 북한 식량사정의 실상과 탈북자들의 북한에서의 영양상태 및 남한에서의 정착 후 영양섭취 변화와 이에 따른 건강상태의 변화를 파악하기 위해 탈북한 일가족 10명을 대상으로 하여, 식이섭취 조사를 실시하였다. 또한 탈북직후와 4개월 후 의료기관에서 검진한 결과를 이용하여 분석한 결과는 다음과 같다. 일반적으로 이들의 체위는 남한의 평균 체위보다 매우 왜소하였으며. 4개월동안 평균 4.5kg 정도의 체중이 증가하였다. 이들의 식생활은 북한에서 주로 감자, 강냉이밥, 강냉이로 만든 국수, 산나물등 식물성 식품위주의 식사였으나 남한에서는 동물성 식품의 섭취가 급격히 증가하였다. 이북에서 이들의 평균 열량섭취량은 한국인 영양권장량에 비교할 때 50% 정도로 매우 낮은 수준을 보였으며, 남한에서도 열량섭취는 증가하지 않았다. 그러나 대부분의 영양소의 섭취는 북한과 비교할 때 남한에서 증가를 보였고, 특히 콜레스테롤 섭취는 급격한 증가를 보였다. 탈북직후의 이들 혈중 알부민, 포토당, 헤모글로빈, 헤마토크리트 농도는 대부분 정상이었으며, 혈액의 지질농도도 정상범위에 속하는 것으로 나타났다. 현재 북한 식량난은 더욱 심각할 것으로 추측할 수 있으나 이들의 거주할 당시의 북한에서는 하루 2끼 식사에 강냉이를 주로 하는밥이나 죽, 그리고 나물 등을 주로 먹은 것으로 나타났다. 명절은 김일성 생일, 김정일 생일, 8.15해방절, 조국 해방전쟁 승리일등이 있고, 이런 명절에서는 설탕, 밀가루등 특별배급이 추가되나 특별한 명절음식은 없는 것으로 조사되었다. 북한에는 양념이 매우 귀하며, 특히 고춧가루가 귀해서 주로 백김치를 담가서 먹고 있었다. 현재 북한에서 가장 필요로 하는 것으로 쌀, 잡곡류, 고기 그리고 참깨 등의 양념류와 의약품 및 비누 등을 제시하였다. 현재 자료수집이 극도로 제한된 상황에서 북한 주민들의 정확한 식이섭취 상태와 영양상태 판정은 불가능한 것으로 사료된다. 본 연구의 대상자가 극히 소수이고, 실제로 이들이 북한에서 소외된 계층이었으므로 본 연구결과가 북한의 사정을 정확히 대표한다고 할 수는 없으나 이들의 조사가 앞으로 북한주민의 영양상태를 판정하는데 중요한 자료가 되었으면 한다. 앞으로 통일에 대비하여 북한 주민들의 식생활의 양상과 정확한 영양상태에 대해 많은 연구가 시도되어야 할 것이다.

In the past, the elements that determine the movie performance were directors, movie stars, the number of opening screens, on-line ratings or distributing agencies. However, the word-of-mouth effect has changed this trends. So the influence of word of mouth grows more and more strong at this stage of the Internet and smart phones being widely prevalent. I fix my sight upon SNS which is one of the medium of arousing the word-of-mouth effect, and I have a purpose to cast light upon a real example of the influence of SNS on the movie performance. The way is to analyze SNS activities that accompany the process of production and showing of , which is said to have had an beneficial effect of SNS among the enormously successful movies last year. It is relevant to provide a new milestone regarding the movie performance through the successful case of SNS activities by examining the word-of-mouth activities through SNS in the manner of the period division of the pre-release, the early stage of release and the maturity.

The aim of this study is to develop a quantified water loss Index to evaluate and manage leakage scientifically for the reduction of non-revenue water in water distribution systems. For the purpose, unavoidable background leakage suggested from UK water industry and IWA, and allowable water leakage in accord with the concept of allowable water loss are proposed by analyzing the inflow into two study water districts and the short-term water use of each customer in the districts. The study distribution areas are selected among the metered districts with good maintenance of leakage after improvement activities in Nonsan, medium sized city in Korea. Estimation models of allowable leakage are developed by metering and analyzing the minimum night flow at residential and commercial areas in the city. In the results of the investigation, it is estimated that background night flow in residential area was larger than that of commercial area where the types of business shows small water use characteristics. Meanwhile, night flow and background water loss on internal plumbing systems show great differences for each district which is influenced much by the water use characteristics and facilities scale. Based on metering water use data in various districts, leakage management criteria can be established under the consideration of domestic conditions in Korea by analyzing separated real water use and background leakage and it is possible to apply into presentation of optimal leakage level and reasonable time for working activities for leakage reduction.
