분무를 정량적으로 측정하는 것은 노즐의 설계와 개발을 위해서 뿐만 아니라 연소 시스템 전반의 효율 및 불안정성의 제거, 공해 저감 등의 요구 조건을 만족하기 위해서 중요하다. 이를 위해 이전에는 분무장 내에 수집관을 삽입하는 기계적 패터네이터(Mechanical Patternator)와 같은 삽입식 측정 방식을 이용하여 왔으나, 최근에는 고속카메라, Malvern particle analyzer, PDPA, 광학 패터네이터(Optical Patternator)와 같은 분무장을 교란시키지 않으면서도 빠른 측정이 가능한 가시화 기술들이 적용되고 있다. 특히 광학 패터네이터는 레이저 평면광을 이용하여 분무를 측정하는 비삽입식 기술로 단시간 내에 분무장 내 액체 연료의 질량 및 액적 크기의 단면 분포를 동시에 얻어낼 수 있는 장점을 갖고 있다. 그러나 분무 액적들의 수밀도가 증가하는 경우에는 이들 액적에 의한 입사광 및 신호 감쇠, 다중산란 등에 의한 오차가 심하게 발생하여, 기존의 PDPA, PLIF 등의 광학 기법으로는 충분히 신뢰할 만한 결과를 얻기가 어렵게 된다. 이러한 분무를 정량적으로 측정하기 위해서는 입사광의 감쇠뿐만 아니라 분무장 내 액적들에 의한 신호의 감쇠 과정에 대한 고려가 필요하다. 주면 액적들의 영향을 최소한으로 줄이기 위해서는 레이저 평면광을 사용하는 광학 패터네이터와 달리 레이저 광선을 분무장에 조사하여 고압에서 나타날 수 있는 다중 산란에 의한 오차를 최소화할 수 있다. 이러한 이미지 처리 기법을 이용하는 광학 선형 패터네이터(Optical Line Patternator)를 이용하여 기존 레이저 계측기법으로 측정이 곤란하였던 고압 환경 하에서의 스월 동축형 인젝터의 분무 특성을 해석할 수가 있다. 2015(년도) 6,388, 2025(년도) 13,367, 2035(년도) 18,756, 2045(년도) 22,595, 시장점유율 증가로 인한 수출액 증가분 누적(억원) : 2015(년도) 3,411, 2025(년도) 8,847, 2035(년도) 14,433, 2045(년도) 18,005 또한 시나리오 비교평가를 실시하여 본 결과, 본 연구에서 정의한 순편익 누적(Cumulative Net Profit) 변수를 적용하면 현재 연구비 추세 대비 $30\%$ 까지 연구비를 증가 시키는 것이 효율적임을 알 수 있었다.성, 생산 용이성, 제품 디자인의 우수한 정도가 a=0.01 수준 하에서 유의적으로 추정되었다. 이들 변수들 중에서 품질경쟁력에 가장 큰 영향을 미치는 측정변수는 제품의 기본 성능, 수명(내구성), 신뢰성, 제품 디자인의 순서로 추정되었다. 이것은 한국 제조업이 아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자

As importance of English has been getting more important with globalization, English education for preschoolers has drawn more attention from parents who were born in 1970's and 1980's. Demands for English education are very intense mainly because parent generation has experienced importance of English through own career and they have only one or two children, resulting parents' willingness to invest more on children's education. In order to response high demands for English education, Korean public education system has introduced more intense English education curriculum for younger children and put more weights on English education even for preschoolers. Even though there are numbers of studies to support effectiveness of English education for pre-school age children, adaption of English education for them without through preparation may cause unwanted results on children's learning experience. Hence, it is imperative to develop guideline for English education targeting pre-school age children based on through studies. The purpose of this paper is to justify English education for preschoolers based on various theories for language acquisition, research effectiveness of edutainment animation for English education, and provide basic guideline to develop edutainment animation in the future. To achieve this goal, this study visits how each theory emphasizes importance of language education in preschool age children and analyzes well-known edutainment animation titles by comparing them per characteristics. Furthermore, specifically from participation-inducing animation for education, each component, such as characters, story structure, & story telling methods, has been discussed. Based on the findings from this paper, basic guidelines to develop edutainment animation are developed by suggesting teaching tools for English education for preschoolers.

The animation is in a boom as the one of rising media content industry of 21st century. So it is very affective to education. For example, in primary or secondary schools, there are extra-animation class after school, and in universities, there are a lot of the department of animation nowadays. In every years, a number of high-educated professionals are coming to the manpower market. This was an affirmative phenomenon for many animation companies to upgrade from OEM(Original Equipment Manufacturing) system to very creative system. They might believed that young, well-educated animators have qualified skills, and creative mind. But, 10 years later, now, there is few professionals who was well-educated in system of Korean animation. Companies still can not hire enough animators. Even if they can find an high-educated person, this person do not have enough skills to do his or her works, so companies need to re-educate this animator for awhile. But, why is very hard to find a skillful new animator? From this question, we will talk about educational condition of animation departments, and condition of employment to markets. And then, we will find the causes of problems which give bad effect to lack of manpower. Finally, we will summarize about policies for supporting animation, so hope to contribute for making better atmosphere for creating animations.

The advertisement is an informative product in which a company or an organization has made a substantial capital investment in order to achieve their goals based on their carefully thought-out plans. David Ogilvy maintaned that making a headline of an advertisement is worth 80 percent completion of the advertisement. As he insisted, a headline is also the most important element in the printing advertisement. Therefore, the importance of selecting headline's font style is increased because, while creating a headline, it is necessary to consider the emotional aspects of the advertising object that attract the attention of people. Many researchers call 'typography' as 'frozen sound' or 'written sound' because typography not only works as a letter but also provide people with an emotional pleasure. An appropriate selection of headline's font style in the advertisement production makes both the client and the audience for the advertisement satisfied because it reduces the communication risk and makes design results more reasonable. It is difficult to find many decision-making methods for selecting headline's font style. Therefore, the author of this paper investigated the trend of the use of headline's font style in order to help the designer understand headline's font style as one of design factors. As a result of the research, it is possible to conclude that, while selecting the headline's font style, the attributes of a font consist of limited style, and more objective and systematic font selection methods are necessary.

This paper attempts to understand the reality of Netflix on the Korean film distribution market environment, and to verify the possibility of developing domestic content centered on independent films in the OTT market, led by Netflix. The research significance of finding the way for Korean diverse films and independent films that cannot be provided with investment and distribution opportunities in various Korean Wave contents will be studied, and the characteristics of Netflix in the Korean film market will be explored. Netflix disseminates Korean contents such as Korean movies and Korean dramas, contributes to the spread of the Korean Wave, and is re-adjusting the paradigm of the distribution market, raising issues that cause a virtuous cycle of profits, controversy over net usage fees, and flooding of Hollywood movies. Considering the nature of intercultural exchange, the interaction between independent film content, Netflix platform, audience, and global market will expand interactive communication opportunities. In other words, just as Netflix uses the Korean media market to make profits, Korea should also use Netflix to try to expand the global market of Korean film contents (K-Film)and maintain a cultural and economic reciprocal attitude.

A stream serve the functions of different water utilization, flood control, and the environment, and contributes to the development of national life and culture. On the other hand, it is difficult to efficiently evaluate various projects, such as effectiveness verification and comparison between projects, because the evaluation procedures and evaluation techniques of projects are not uniform and different for each institution. Therefore, a standardization technology was developed for a post-assessment of stream projects that can recognize stream problems and comprehensively evaluate stream-related projects. To this end, various projects, such as project evaluation techniques, national R&D projects, and social welfare projects, were compared and analyzed, and the standardization stages of the project were first suggested. In addition, based on the standardization stage, the evaluation indices for each stage were derived to develop an evaluation table that can evaluate stream-related projects comprehensively. Finally, it is possible to prevent the repeated use of failure factors in the planned projects.

1997년 IMF 경제위기 이후 한국사회의 뚜렷한 변화의 하나는 빈부격차의 확대와 함께 사회계층의 양극화가 진행되고 있다는 점이다. 이 논문의 목적은 사회적 양극화의 주요 원인은 무엇이며, 사회적 양극화가 공간적으로는 어떻게 나타나는가를 서울을 사례로 하여 규명하는 데 있다. 서구 선진자본주의 국가에서 사회적 양극화에 대한 논의는 이미 1990년대 초 세계화 또는 세계도시가 주요한 연구주제로 등장하면서 시작되었다. 1980년대 이후 선진자본주의 국가를 중심으로 한계에 도달한 포드주의 축적체계가 포스트 포드주의로 급속히 전환되면서 사회적 양극화가 자본의 유연화 및 세계화 전략과 맞물리는 현상으로 인식되었기 때문이다. 이런 점에서 최근 전개되고 있는 한국의 사회적 양극화는 서구 선진국과 유사하다. 1997년 경제위기 이후 세계화가 급속히 진행되는 가운데 지식기반경계의 대두로 고소득 전문직이 등장하는 반면, 중산층의 몰락과 더불어 임시적 고용이 확대되고 실업이 만성화되는 등 자본의 세계화와 유연화 과정에서 나타나는 양극화 양상이 보이기 때문이다. 이와 같은 맥락에서 한국의 사회적 양극화는 이미 1990년대 초부터 진행되어 왔으며, IMF 경제위기는 단지 그러한 사회적 양극화를 급속히 진행시키는 방아쇠 역할을 하였다고 할 수 있다. 그러나 양국의 사회적 양극화는 직업구조와 임금소득의 격차만으로 설명하기 어려운 또 다른 특성을 갖는다. 왜곡된 시장구조에서 무엇보다도 부동산과 같은 자산소득의 격차가 큰 역할을 하기 때문이다. 서울은 이와 같은 한국의 사회적 양극화가 한 도시 내에서 전형적으로 전개되는 곳이라고 할 수 있다. 한국 내 어떤 도시보다도 세계화되어 있고 전문지식을 기반으로 하는 산업이 발달하고 있기 때문이다. 서울의 사회적 양극화는 공간적으로도 나타난다. 일반적으로 서울은 크게 주거지로서는 공동화되고 있는 중구 종로구 용산구 등 사대문안의 구도심지역, 강남구 서초구 송파구 등을 중심으로 한 1970년대 이후 계획적으로 계발된 이른바 강남의 신흥주택 및 신산업 지역, 영등포구 구로구 금천구 성동구 동대문구 등 제조업 중심의 구 산업 및 저소득층 주거지역 그리고 그 나머지 강북 강서 강동 등의 전형적인 주거지역 등 4개 유형으로 지역이 구분된다. 그러나 IMF 경제위기 이후에 강남구 서초구 송파구를 중심으로 하는 고소득증의 주거지와 그 나머지 주거지로 공간적 양극화가 이루어지고 있다. 사회적 양극화의 이와 같은 공간화 과정에는 자산소득의 격차를 확대하는 강남구 서초구 송파구의 높은 지가 및 아파트 가격이 중요한 역할을 하고 있다. 높은 부동산 가격이 이 지역에 대한 일종의 진입장벽을 참음으로써 고소득층에 의한 공간독점을 가능하게 하기 때문이다. 공간적 양극화를 촉진하는데는 지하철 및 문화복지시설의 집중 둥 불균형적인 공공투자와 강북에서 이전한 명문고등학교를 중심으로 형성된 8학군 등 양호한 교육환경 또한 중요한 역할을 하고 있다. 서울의 사례에서 확인할 수 있듯이, 한국에서의 사회적 양극화는 직업구조와 임금소득이라는 일반적인 요인 외에도 부동산 가격 및 소득 그리고 생활인프라의 격차를 통해 공간적 양극화물 야기하고 있다. 이러한 현상이 한국내 다른도시에서도 전개되고 있는지, 공간적 양극화로 인한 도시문제는 무엇이고 대처방안은 무엇인지 등에 대해서 후속연구가 요구된다.

This paper reports the political supporting platform, and the outcome evaluation model, which was developed for the Korean on-line game companies that have started to go abroad to publish their games. When they begin to sell their games, they have many difficulties in promoting in other countries including the USA & EU. They try to find solutions to solve these problems, but on-line games still do not have a successful business model because of their unique attributes and environmental features, even though they spent a lot of money and time to enter the international on line game market. Thus far, the local on-line game supporting policy has tried to improve the world competitiveness of local companies by doing diverse activities, such as Global Service Platform(GSP) service, international game competition, and globalization, marketing. On the other hand, there has been only a small number of fruitful results except for GSP. Therefore, in this paper, the result of GSP was verified using the Global on-line game Supporting Chain Model(GoGSCM), which is the new political supporting and evaluation model through survey targeting GSP participations. As a result, GSP was evaluated based on the compatibility, efficiency, effectiveness, and continuity.

Generally, electricity market has monopoly market structure because of need of enormous investment for infrastructure. However, the introduction of competition in network industry as electricity is a tendency of the world with decreasing the effects of economy of scale due to the advancement of technology. Now, electricity industry restructuring is in progress but the competition in electricity retail market is not in force yet in Korea. Whether a effective competition exist or not is very important to policy decision maker who drive restructuring, but there are small numbers of quantitative researches on that. In this study, we estimated the effectiveness of competition in the electricity retail market through switching costs. If switching costs are high, consumers actually can be locked in incumbent firm in spite of introduction of competition. Therefore switching is a critical factor to determine effectiveness of competition and to estimate the size of switching costs quantitatively can proffer the information about whether the competition in the electricity retail market is effective or not in the future. We estimated switching costs using consumer' stated-preference data by conjoint analysis. In according to estimation results, the cost of switching process is not so high, but the relative brand loyalty of an incumbent company is significantly high. And the price is considered as the most important factor choosing an electric service commodity. Based on the empirical results, it is possible to analyze the relationship between suppliers' competitiveness resulted from management efficiency and customers' switching possibilities. The paper therefore provides guidance for suppliers in deciding to enter into retail competition and for policy makers in introducing retail competition. And it has a significance of estimating the switching costs directly.
