Research on what factors affect the success of the movie market is very important for reducing risks in related industries and developing the movie industry. In this study, in order to find out the degree of correlation of independent variables that affect movie performance, a survey was conducted on film experts using the AHP method and the importance of each measurement factor was evaluated. In addition, we hypothesized that factors derived from big data related to search portals and SNS will affect the success of movies due to the increase in the spread and use of smart phones. And a prediction model that reflects both the expert survey information and big data mentioned above was proposed. In order to check the accuracy of the prediction of the proposed model, it was confirmed that it was improved (10.5%) compared to the existing model as a result of verification with real data.Therefore, it is judged that the proposed model will be helpful in decision-making of film production companies and distributors.

The purpose of this study is to analyse the complexity of Vietnam's cultural policy in the socio-economic context of socialism-oriented reform with a focus on the case of 'socialization'(xa hoi hoa) cultural policy. The Vietnamese socialization policy has been adopted to mobilise resources and participation from 'the whole society' in order to promote the development of culture and arts. Although there remains the discourse of its definition, the socialization policy has showed its achievements in mobilizing financial resources, privatization, enhancing decentralization, and revitalizing the private investment, and thus help improve cultural services in both quantity and quality. The socialization policy illuminates the leadership of the state, yet gradually improved in promoting and practicing cultural policy. This study is expected to enhance understanding of Vietnam's cultural policy after reform to the Korean scholars, therefore it contributes to boosting the cooperation and cultural exchange between Vietnam and Korea.

정수장에서 소독 및 여과 처리가 완료된 깨끗한 물은 배급수시설로 전달되나, 실제로 관의 노후화, 갑작스러운 유향 변동, 특정 구역의 관 내 정체 시간에 따른 Water Age 상승 등 여러 요인으로 인해 실제 수용가에는 안전하지 않은 용수가 공급될 가능성이 있으며, 이에 따라 적절한 위치에서 지속적인 감시를 통한 조기 발견 및 조치가 필요하다. 상수도 시설기준(2010)에 배수시설의 주요 지점 혹은 관 말단 등 필요에 따라 적절한 위치에 수질 계측기를 설치할 수 있도록 제시되어 있으나, 계측기 설치 위치나 개수에 대한 기준이 모호한 실정이다. 모든 구역에 수질계측기를 설치하여 감시하는 것이 이상적이지만, 현실적으로는 지자체 환경 및 경제적인 한계가 있어 주요 위치에 설치하는 것이 바람직하다. 본 연구에서는 대표적인 수리해석 모형인 EPANET을 사용하여 대상 관망의 노후도, 유속, 유향변동 등의 영향인자를 바탕으로 수질사고가 발생할 확률이 높은 관을 위험관으로 선정하고, 선정된 위험관을 대상으로 최단 경로와 Cost를 산출할 수 있는 Floyd Warshall Algorithm을 이용하여 각 Node(수용가)간 물이 이동할 때의 최소 도달시간과 경로를 파악하였다. 또한, 시간 서비스 수준(Level of T hour Serivice)의 개념을 도입하여 위험관으로부터 특정시간 이내에 흐름이 도달하는 Node를 파악한 뒤, 그 중 가장 많은 피해를 발생시킬 수 있는 위험관을 수질계측위치 지점으로 선정하였다. 제시된 수질사고 발생위험이 높은 위험관을 대상으로 수질계측 위치를 선정하는 방법이 전체 관망 네트워크를 대상으로 수질계측 위치를 판단하는 방법보다 결과 신뢰도 측면에서 더욱 효과적이고 효율적인 방법으로 사료된다.

This study examines the impact of factors that affect Hollywood movies' box office performance, using a sample of 149 movies that were ranked number 1 on the first week of release between 2014 and 2018. Such factors as production budget, the number of opening screens, the valence and volume of both critics and netizens, rating, distributor's power, remake, high season, genre are introduced to analyze box office performance. The result shows that the determinants of the US box office and the total box office are different. Considering the difference in budget by genre, the number of opening screens is not influential in the US box office performance of all genres with production budget of less than $100 million. The result suggests the need to refine more elaborated models for future research on box office performance.

It's important to analyse effects of word of mouth for making its impact higher in performance of motions pictures. And it's required to combine variety sales activities like free gift, promotion goods and price discount with word of mouth for the box office of film. The purpose of this study is to compare between groups classified by demographic characteristic into effects from word of mouth and methods of sales promotion in intention of watching film. On the other hand existing studies on sales activity and word of mouth were one-sided in theoretical background, a meaning of this study is theorizing a social phenomenon about sales promotion of movie giving actual examples that currently are effected by production company, Movie theaters, distribution company and affiliated company. For this purpose, it conducted a survey targeting 500 students in B university in Seoul city and 379 answers got received, and it proceeded this study with 369 answers except 10 inaccurate ones. Creating questionnaires with Likert 5 point scale, it decided that case of substantial inclination was 5 points and inverse one is 1 point. Doing analysis T and ANOVA according to male and female, kinds of major study and number of average monthly watching movie, it analysed the test results after comparison analysis between classified group. The results are summarized as follows: First, offering premiums is more effective by masculine than feminine, but situation of free gift is an opposite result. Second, there are no differences of effects word of mouth and methods of sales promotion by majority departments. Third, there are much differences between groups classified by average number of watching film in a month into effects from word of mouth and methods of sales promotion. Group of watching film more 3 times in a month is more effective than the other groups in intension of watching film by word of mouth. Fourth, word of mouth is great factor to increase intention of watching film and second one is discount on the price.

Non-revenue water reduction(NRW) technologies are implemented to evaluate and manage leakages scientifically in water distribution systems under local governments. A development of quantitative leakage indicator by measuring minimum night flow, pressure control policy by installation of PRV(pressure reducing valve) and the establishment of leakage prevention schemes by residual life modeling of deteriorated water pipes are reviewed and studied. Estimation models of allowable leakage are developed by measuring and analyzing minimum night flow at residential and commercial area in Nonsan city, which is suggested from UK water industry and can improve an existing leakage indicator for the evaluation of non-revenue water. Also, pressure control method is applied and analyzed to Uti distribution area in Sacheon city in the operation aspect. As results, $466\;m^3/day$ of leakage can be reduced and it is expected that 113million won of annual cost can be saved. In the part of corrosion velocity and residual life assessment, non-linear prediction models of residual thickness are proposed by assessment of corrosion velocity based on exposure years, soil and water quality etc., since the deteriorated water pipe play a major role to increase leakage. It is expected that collection data and analyzing results can be applied effectively and positively to reduce non-revenue water by accumulating surveying data and verifying the results in the business field of water distribution systems under local governments.

Over the years(1971 to 1987), only 20 Korean film production companies had been granted the exclusive rights to make Korean films in Korea and to import foreign films with a quota system. They had been making trashy Korean movies to secure import quotas of foreign films. Newcomer's entry of market had also been limited and the growth of Korean films through innovation had been hampered. In the same period, The annual number of Rookie director is 10, the portion of debut films of all Korean films is 10.62%, and the audience portion of debut is only 10.5% of Korean movie audience. From 2004 to 2016, total number of rookie directors is 874, and 61.72% of 1,416 directors who made his debut over the 46 years from 1971 to 2016. This is far more than the number of directors who debuted for the last 32 years. From 2004 to 2016, the annual number of rookie directors is 62.15 and their debut film occupies 39.58% of the total amount of Korean movies released and 32.8% of the audience number. Since the full opening of the domestic market to foreign films industries in 1988, the liberalization of independent film production in 1999, as a result of innovation of a competitive system, the Korean movies have been loved by audiences. However, there are concerns that the decline of the screen quota in 2006, the monopoly of the 4 major distributors, increase in indie movies and Semi-adult movies for VOD, could be the potential threat for future innovation in Korean cinema.

The current distribution structure in Korea film industry is in the multiplex chain. As a result, most small or medium-sized theaters have been excluded from the market, and all the multiplex chain have gradually been formed into the vertical integration structure. The strike by multiplex theaters in Chuncheon who did not screen for one month led to the problem of the vertical integration, which resulted in many effects. Particularly, it caused considerable effect on the cultural desire and instigated movie-goers to turn to illegal content. This study surveys the process in which Korean multiplex theaters in vertical integration structure took over the Korean film market, and consequently, small theaters collapsed, and the theaters in vertical integration structure kick out small theaters in horizontal integration structure, and conducts a survey on the effect of the one-month strike by Chuncheon CGV from September 27 to October 30, 2008 in Chuncheon where said processes had completed so as to determine the effect of and impact of the problem of the vertical integration, monopoly structure. When major consumers of the film industry, i.e., people in their 20s, see their access to newly released films limited due to closing of multiplex theaters, they feel the impulse to access illegal contents. If they miss viewing the newly released films, they prefer to view illegal contents or films on recording media rather than visiting theaters showing those films. They are also influenced by timing of film release. Specifically, methods of illegal access to newly released films, permanent accessibility to them via recording media, and timing of film release influence their viewing patterns.

Recently, demands for generating high quality tap waters are increasing with high concern of water pollution and corrosion of water pipelines. For the reasons, developing water quality stabilization technique in water purification system is sought rather than replacing to a new pipelines. In this study, high-purity liquid lime($Ca(OH)_2$) was introduced for a water quality stabilization technique in water purification process and simulated water distribution system of pilot-scale size was applied to evaluate anti-corrosion control effect. The effect of anti-corrosion control was calculated in terms of LSI(Langelier Saturation Index) In conclusion, the result of pilot plant showed improvement of corrosiveness by liquid lime($Ca(OH)_2$) with reduction of released iron(Fe). Application of anti-corrosion control technique to the mild steel coupon and the copper coupon were effective by indicating 35.4, 44.5% of improvements. Besides, sample pipes which were treated with liquid lime had formated more thicker layer of corrosion product inside of pipes. As a result, the process of injecting water stabilizer can greatly contribute to the high quality of tap water.

The purpose of this study is to determine the meaning and function of black and white in the comic strip, which are mounted on the book pages. The role of space in comic strip, compared to the role of time in the cinema, enable to feel the role of the time in the book. Therefore storytelling of comic strip has been placed in the inseparable relationship with space. My aim is to think about the black and white meaning in the visual media, especially the use of black and white which is highlighted in the comic strip. Black and white doesn't mean a loss of color in the comic strip but it works around 2 important notions : readability, modernity (with minimalism). In comic strip, 'black and white' is not a true colour but it is complex items which indicate symbolic significances. Moreover it is also a notion which enhance 'existence and absence' and 'visible and invisible'. That's why to analyze and to understand how the space is organized in comic strip page, i chose several examples extract from black and white comic strip.
