The purposes of this study are to analyze how the media reflects the source competition between the activist group and the governmental source in the news contents. Media ideology and the conflict phase also were chosen as situational variables for evaluating how those variables could influence the source competition process. To answer the proposed research questions, the study chose the 'screen quota' issue as a research unit and analyzed documents from three sources, media news, the activist group for maintaining screen quota, and the governmental source during six years and three months. The results showed that the government source played a primary definer role in media reporting related to the screen quota issue, compared to the activist group. The governmental source's primary definer role was maintained against the highly contested social issue while the media ideology, to some degree, leveraged the activist group's comparatively unstable primary definer power. The governmental source's primary definer role was escalated as the conflict phase evolved.

The purpose of this research was to derive political suggestion to increase the demand for forest visit by analyzing the demand of forest visitors, focusing on the residents of Seoul and capital areas. The determinants of demand, which is the number of forest visit in a year, were analyzed by independent variables; six factors from factor analysis on selective attributes, demographic characteristics, and other variables related with the general matters when visiting a forest. As a result, among the independent variables, selective attribute (tourism resource factor), gender (male), and residency (Seoul) were found out to have positive(+) effect on demand for forest visit. However, other selective attribute (external factor of forestry), occupation (white-collar employee), and level of education (over college graduate) were found out to have negative(-) effect on demand for forest visit. Based on these results, implications for the expansion of demand for forest visits were derived.

80 년대 이후 국내 뮤지엄은 양적으로 많은 성장을 이루었고, 현재 전국에는 200 여 개의 뮤지엄이 개관 중이다. 이 중 많은 뮤지엄들이 기존의 역사나 자연사를 주제로 한 뮤지엄과는 다른, 다양한 주제와 내용을 다루는 '테마 뮤지엄' 을 표방하고 있지만 여러 면에서 외국의 선진 테마 뮤지엄에 비해 열악한 것이 사실이다. 이에 본 연구에서는 완성도 있는 테마뮤지엄을 위해서 테마뮤지엄의 구조를 내러티브 특성에 따른 고찰을 통해 구조적으로 이해하고자 하였다. 이에 본 연구에서는 테마뮤지엄의 속성을 규명한 후, 완성도 있는 테마뮤지엄의 실현을 위해서는 뮤지엄 내 내러티브성의 확립이 필수적이라는 가설을 검증하고자 하였다. 또한 이를 통해 테마뮤지엄의 기본 속성이 내러티브 구조에 있음을 논증하고 이러한 내러티브 구조가 명확히 드러나는 테마뮤지엄을 실현하기 위한 디자인 방법론적 접근으로써 테마뮤지엄의 내러티브구조 확립을 위한 방법틀을 제안하였다. 이 방법틀은 테마뮤지엄의 내러티브 구조, 내러티브 유형별 포지셔닝맵, 내러티브 체험과 재방문력 창출의 상관 정도를 제공함으로써 테마뮤지엄 디자이너의 내러티브 구조에 따른 디자인 개선책 도출을 도울 수 있을 것으로 사료된다. 또한 제안한 방법틀의 디자이너와 사용자 간 수용도를 알아보기 위해 사례연구를 실시하였는데, 그 대상으로 국내 뮤지엄 가운데 8 곳을 선정하였다. 이를 통해 내러티브 구조에 따른 디자인 계획이 관람객의 만족도에 큰 영향을 미침을 입증할 수 있었다. 이상의 연구는 국내 중소규모 테마뮤지엄의 질적 성장에 기여할 것이며, '테마'라는 특성을 가진 환경에 확대하여 적용할 수 있을 것으로 사료된다.

Despite a number of previous studies about cultural tourism festivals, studies on food menus in the cultural tourism festival setting have often been neglected. Considering the importance of food menus, identifying major selection attributes that satisfy visitors in a festival setting is vital. Using conjoint analysis, this study demonstrated that price was the most influential selection attributes to attract visitors. The time required between ordering and receiving food was found to be the second important selection attribute, followed by menu and place. Cluster analysis identified two distinct segments that take different sets of elements into account when making their selection decision. Conjoint simulation estimated the most preferred foodservice form in cultural tourism festivals setting would have 21.18% potential market share. The implications gained from this study provided an important starting point for determining key selection attributes in establishing strategies to enhance visitors' level of satisfaction.

Recently, comics pulication industry is experiencing long-time recess in Korean market. To overcome the difficulties firms are trying to develop various tools which fit new technological environments, but previous research tend to have focused too much on web-base contents such as webtoons, rather than communication effectiveness through social network services. Thus, this study investigated the relationship between the characteristics of postings at social network service and the consumer responsiveness. In the results, we found that posting with visual images and event invitations were positively associated with consumer responsiveness, and the amount of information was negatively associated with the responsiveness. This study shows some implications on how firms can effectively enhance communication with consumers through social network service.

This paper presents optimal configurations of multidimensional path indexes (MPIs) for the efficient execution of object-oriented queries in object databases. MPI uses a multidimensional index structure for efficiently supporting nested predicates that involve both nested attribute and class hierarchies, which are not supported by the nested attribute index using one-dimensional index structure such as $B^+$-tree. In this paper, we have analyzed the MPIs in the framework of complex queries, containing conjunctions of nested predicates, each one involving a path expression having target classes and domain classes substitution. First of all, we have considered MPI operations caused by updating of object databases, and the use of the MPI in the case of a query containing a single nested predicate. And then, we have considered the use of the MPIs in the framework of more general queries containing nested predicates over both overlapping and non-overlapping paths. The former are paths having common subpaths, while the latter have no common subpaths.

With the development of smartphones, the number of applications for smartphone increases sharply. As a result, users need to try several times to find their favorite apps. In order to solve this problem, we propose a recommendation system to provide an appropriate app list based on the user's log information including time stamp, location, application list, and so on. The proposed approach learns three recommendation models including Naive-Bayesian model, SVM model, and Most-Frequent Usage model using temporal and spatial attributes. In order to figure out the best model, we compared the performance of these models with variant features, and suggest an hybrid method to improve the performance of single models.

기술의 복합성이 증가하고 제품의 존속 수명주기가 불확실해지면서 기술개발자가 의도하는 바와는 관계없이 사업 영역과 기술기반의 변하고 있다. 이러한 환경 속에서 산업 내 기술의 특성을 분석하는 이른바 산업기술분석 역할은 매우 중요하다. 그러나 그 범위가 매우 광범위하고 그 중 기술개발에 있어 관련된 산업기술분석의 프레임이 구체적으로 적용된 사례를 제한적이다. 따라서 다양한 산업을 지원하는 정부 기술개발 기회의 경우, 반도체에 적용되는 모듈러 기반 기술개발 틀과 성과분석이 항공기, 지능형 로봇과 같은 복합 시스템 산업에 그대로 적용해왔던 것이 현실이다. 이는 기술을 제품화함에 있어 필수적인 개발시스템의 기술적 속성이 산업기술 분석 방법론에 효과적으로 체화되지 못했기 때문이다 본 연구는 시스템과 서브 부품으로 구성되는 제품설계 특성을 구조화한 제품 아키텍쳐 이론을 소개하고 이를 기술개발체계에 적용하는 실증적 연구를 수행한다. 실증적 분석을 위해 항공기 개발 전 과정을 분해하고 아키텍쳐 분석방법을 실제 적용하였다. 아키텍쳐는 대표적으로 모듈 형(Module)과 인테그랄 형(Integral)으로 구분한다. 실제로 한 가지의 제품 안에도 모듈형 부품과 인테그랄 형 부품이 복합적으로 혼합되어 있는 경우가 많다. 또한, 제품을 어느 레벨까지 분해할 지에 따라 모듈화의 정도도 달라 질 수 있다. 본 연구는 아키텍쳐 중 Integral 속성의 정도를 파악하여 아키텍쳐 정도를 파악하였다. 측정 기준으로 첫째, 타 부품과의 기능적인 상호연관성과 둘째, 체계종합 설계와의 상호의존성 두 가지를 설정하였다. 이러한 두 가지 아키텍쳐 기준을 547개의 항공우주 부품 및 기술을 적용해 본 결과, 항공기 개발과정은 총 $65\%$의 인테그럴 속성을 가지고 있으며 기술분야 별로 아키텍쳐 정도가 다르게 나타나고 있었다(전자 부품은 분야는 오히려 모듈형에 가까웠음). 비단 항공기 개발과정 뿐만 아니라 다른 산업, 제품에도 적용될 수 있는 틀을 마련함으로써, 기존 연구개발기회에서 산업기술 분석을 통한 체계적 기획으로 전환할 수 있는 새로운 대안을 제시한다. 결과적으로 산업기술의 특성과 구조를 반영한 기술개발 방법론으로 아키텍쳐 이론을 적용할 수 있는 단초를 마련했으며, 이것은 본 논문이 기대하는 바이기도 하다.

An NPC grouping method is proposed for various 3D games depending on their characteristics. Immovable objects tend to have particular orientation features in their Gabor filtering results whereas the movable objects controlled by AI appearing as a human or an animal do not. First of all, We analyzed directional and frequency domain features in the NPC object and configured them as 24 Gabor filter banks. Then, 24-dimensional feature vectors according to the scale and direction of the filter are calculated. Each extracted vector represents the energy of a certain direction. This energy indicates the particular direction strength of the object texture. Thus, using this property, NPCs could be grouped as artificial objects and natural objects effectively and it draws the game more speed and strategic actions as a result.
