The prolonged untact era, which has continued since the end of 2019, further accelerated the spread of distribution platforms that provide cultural contents in digital form. Digital content distribution platforms are fiercely competing in the market as the central axis of cultural content planning, production and distribution. In this study, we apply the open innovation theory as a competitive element of digital content distribution platforms to assess whether competitiveness can be secured in terms of multilingualization of content.

본 논문에서는 웨이브렛 신경회로망을 사용하여 알려지지 않은 비선형 시스템을 안정하게 적응 제어하는 문제를 다룬다. 비선형 시스템의 정확한 제어는 함수를 근사화하는 데 사용된 함수 근사화기의 정확성과 효율성에 의존한다. 이에 비선형 시스템 제어에 기준 함수의 선택이 자유롭고 함수 근사화 능력이 뛰어난 웨이브렛 신경회로망을 사용한다. 초기 웨이브렛 신경회로망 제어기 설정은 웨이브렛 신경회로망 변수인 신축과 이동 값을 제어기 입력의 시-주파수 특성을 분석해서 구하고, 연결강도는 Lyapunov 안정성 이론에 기초한 적응 법칙을 사용하여 조절한다. 이를 비선형 시스템인 역 진자 시스템에 적용한다.

The purpose of this study was to explore a support model for domestic ICT companies to advance into overseas markets suitable for the post-corona era along with the rapidly changing global economic situation. As a result of the analysis, first, by analyzing the internationalization cases of domestic ICT companies through the realization theory, in the COVID-19 situation, domestic ICT companies organically respond to crisis situations through ad hoc responses, use of international networks, use of external organizations, and resource-based practices. Through qualitative analysis, we were able to confirm that we are growing overseas while achieving our goals. In addition, strategies for domestic ICT companies to grow through internationalization were derived. Ultimately, it was interpreted as a part that required advancement of government policy according to the government's overseas expansion support system.

This study was conducted to quantitatively analyze the temporal change of green space network at multi-scales from 1975 to 2006 with the application of graph theory in Seoul, Korea. Remarkable change of connectivity was detected in green space networks at the scale ranging from 1,000 ~ 1,600 m during 30 years. Green spaces and their networks have been restoring after 1990 since forest areas had been fragmented in 1975. In 2006, we identified the important core habitat areas that can sustain diverse wildlife species and stepping stones composed of small patches that can link these core habitat areas. Green spaces showed high correlation with the relative importance value of green space connectivity. So, this study could graphically represent green space networks of Seoul City. Green spaces of core areas distributed at the northern and southern boundary, and those of stepping stones possessing the high value of betweenness centrality consisted at the middle, eastern and western boundary. These results indicate that green space network can be graphically and quantitatively explained by degree centrality, betweenness centrality and relative importance value of connectivity with the application of graph theory.

언어가 아닌 다양한 지식원으로부터 그것을 설명하는 텍스트를 생성하는 텍스트 생성 (text generation)은 여러 가지 복합적이고 단계적인 과정을 거쳐 이루어진다. 자연스러운 텍스트를 생성하기 위한 여러 단계 중, 지식원으로부터 텍스트에 포함되기 위해 뽑힌 정보들간의 순서를 적절히 결정하는 과정을 텍스트 구조화(text structuring)라고 한다. 텍스트 구조화는 생성될 텍스트의 결속성(coherence)을 크게 좌우하므로, 양질의 텍스트를 생성하기 위해서는 텍스트 구조화를 다루기 위한 정교한 방법론이 요구된다. 본 논문에서는 SA(simulated annealing) 알고리즘을 이용해 추계적 텍스트 구조화 방안을 제안하며 특히, SA의 평가 함수(evaluation function)로서, 총 4가지의 방법론-중심화 이론(centering theory)을 이용한 센터 전이 유형의 선호도, 추론 비용에 근거한 전이 유형간의 선호도, 서두 문장을 결정하기 위한 가중치 할당에 따른 선호도, 인접한 문장간의 유사도에 따른 선호도-을 제안하고 실험을 통해, 그 효용성을 보였다.

Among the desirable properties of a piecewise linear parameterization, guaranteeing a one-to-one mapping (i.e., no triangle flips in the parameter plane) is often sought. A one-to-one mapping is accomplished by non-negative coefficients in the affine transformation. In the Floater's method, the coefficients were computed after the 3D mesh was flattened by geodesic polar-mapping. But using this geodesic polar map introduces unnecessary local distortion. In this paper, a simple variant of the original shape-preserving mapping technique by Floater is introduced. A new simple method for calculating barycentric coordinates by using straightest geodesics is proposed. With this method, the non-negative coefficients are computed directly on the mesh, reducing the shape distortion introduced by the previously-used polar mapping. The parameterization is then found by solving a sparse linear system, and it provides a simple and visually-smooth piecewise linear mapping, without foldovers.

The aim of this study is to reveal the categorizational and classificatory features of the subject-based classification (SBC) as a subject organization system. For this purpose, 12 SBC schemes of public libraries were selected and a comparative analysis was made between the traditional classification system, such as DDC and SBC in terms of the categorizational aspects, and canons for the classification. As a result, there were significant and considerable differences between the two types of classifications. This study concluded that SBC cannot be clearly explained and understood without a consideration of its essential and distinctive characteristics as a classification scheme.

건축에 있어서 이론과 실제의 관계 문제는 오랫동안 건축 담론에 대한 주요 대상이 되어왔다. 이는 건축에서의 발전이 역사적으로 동시대의 사회적, 문화적, 경제적 환경의 진화와 더불어 진행되어 왔기 때문이며, 건축작업 선상에서 대두되는 이론과 실제의 관계와 맥락성이 건축의 주체성에 매우 중요한 요소로 여겨지기 때문이기도 하다. 1960년대부터 불거진 포스터모던주의의 사고적 영향은 건축분야의 의미와 가치에 있어서 학문과 실무분 야에서 새롭게 재조명되기 시작하였고, 기존 건축고유의 영역을 벗어나, 역사, 이론, 비평, 기술 및 디자인 분야로 확장되어 새롭고 다양한 접근 방법과 그 방식에 대한 고민을 추구하기 시작하였다. 건축작업에 중요한 근거를 제시해주는 비평적 사고를 유지하기 위하여, 이론적인 아이디어에서 실질적인 실무로서의 투사방법, 그리고 그 사이의 절충을 지속하기 위함은 특히 현대사회에서 더욱 복합적이며 다면적인 질문이 되고 있다. 이 논문은 건축의 투사 방법에 있어서 현대 건축가들이 자신들의 이론적인 관점과 그 관점을 건축적으로 가시화 시키는 관계성을 관찰하고, 어떻게 본인만의 논리와 프로세스를 추구하고 지속하는가에 대한 점을 연구하는데에 그 목적이 있다.

This study considered the transition of changes in social status of the film through the discourse analysis of printed media, having been published since 6th revised film policy in 1987. For the purpose, Pierre Bourdieu's cultural sociology, or 'Field theory approach' was engaged as a theoretical background. On the basis of that theory, changes in social status was divided into expert and popular field. From 1988 to 2007, doctor's and master's theses on filmologie and the representative academic journal, "Film Studies" were examined with regard to area of expertise, and movie-related books with regard to popular one. This study demonstrated that the symbolic capital had inhered in the cinematic field along with specialization and diversification of analytic aspects, and the relation between the academic approach and political consideration had performed an important role in intellectualization of film.

The purpose of this work is to explore the role of international entrepreneurship(IE) in explaining internationalization process of Korean ventures and to structure the model of IE with the logics of effectuation. The internationalization of entrepreneurial company is regarded as the realization of entrepreneurship which find out and use opportunities across borders in this point of view, and the realization process gets more realistic and applicable to the internationalization of ventures by effectuation. So we constructed the new concepts of the generating-internationalization-outcome capability(GIOC), which is the effectual capability allowing ventures to go international despite their lack of internal resources and experiences. Its sub-capabilities of GIOC are extemporaneous coping capability, perform-resource-in-hand capability and network-use capability. The empirical analyses of the relations among the capabilities and the performances of internationalization are performed in order to prove the rationale of the model, which provides finally significant evidences of the relationships. The key contribution of this study is that it highlights the important role of IE in internationalization of ventures and shows the possible role of effectuation in explaining the realization process of IE.
