  • Recently many researches have been presented to improve the clustering performance of gene expression data by incorporating Gene Ontology into the process of clustering. In particular, Kustra et al. showed higher performance improvement by exploiting Biological Process Ontology compared to the typical expression-based clustering. This paper extends the work of Kustra et al. by performing extensive experiments on the way of incorporating GO structures. To this end, we used three ontological distance measures (Lin's, Resnik's, Jiang's) and three GO structures (BP, CC, MF) for the yeast expression data. From all test cases, We found that clustering performances were remarkably improved by incorporating GO; especially, Resnik's distance measure based on Biological Process Ontology was the best.

  • In this paper proposed a feature fusion and spatial attention-based modified YOLOv4S for small and occluded detection. Conventional YOLOv4S is a lightweight network and lacks feature extraction capability compared to the method of the deep network. The proposed method first combines feature maps of different scales with feature fusion to enhance semantic and low-level information. In addition expanding the receptive field with dilated convolution, the detection accuracy for small and occluded objects was improved. Second by improving the conventional spatial information with spatial attention, the detection accuracy of objects classified and occluded between objects was improved. PASCAL VOC and COCO datasets were used for quantitative evaluation of the proposed method. The proposed method improved mAP by 2.7% in the PASCAL VOC dataset and 1.8% in the COCO dataset compared to the Conventional YOLOv4S.

A Study on the Coexistance of Ganghak(講學) and Yusik(遊息) space of Oksan Confucian Academy, Gyeongju: Directed Attention Restoration Theory Perspectives (주의집중 피로회복이론의 장으로 본 경주 옥산서원 강학 및 유식공간의 일원적 공간성)

  • This study attempts to understand and explain how "Directed Attention Restorative Environment (DARE)" is managed and fostered in "Gang-Hak (講學)" and "Yu-Sik (遊息)" spaces both inside and outside of Oksan Seowon Confucian Academy, Gyeongju. Directed Attention is a pivotal element in human information processing so that its restoration is crucial for effective thinking and learning. According to Kaplan & Kaplan's Attention Restoration Theory, an environment, in order to be restorative, should have four elements: 'Being Away,' 'Extent,' 'Fascination,' and 'Compatibility.' We could confirm OkSan Seowon Confucian Academy has an inner logic that integrates two basically different spacial concepts of "Jangsu" and "Yusik" and thus fosters the Attention Restorative Environment. Particularly, the Four Mountains and Five Platforms (四山五臺) surrounding the premises provides an excellent learning environment, and is in itself educational in terms of the Neo-Confucian epistemology with "Attaining Knowledge by way of Positioning Things (格物致知)" as its principle precept, and of its aesthetics with "Connectedness with Nature" as its central tenet. This study attempts to recapture the value of Korea's cultural heritage concerning the Human/Nature relationship; and it may provide useful insights and practical guidelines/grounds in designing today's schools and campuses, where the young people's needs for the Directed Attention- and Attention Restorative- Servicescapes seem to be greater than ever.

  • Designing a multilevel database application is a complex process, and the entities and their associated security levels must be represented using an appropriate model unambiguously. It is also important to capture the semantics of a multilevel databse application as accurate and complete as possible. Owing to the focus of the IDEA Methodology for designing the non-secure database applications on the data-intensive systems, the Object Model describes the static structure of the objects in an application and their relationships. That is, the Object Model in the IDEA Methodology is an extended Entity-Relationship model giving a static description of objects. The IDEA Methodology has not been developed the multilevel secure database applications, but by using an existing methodology we could take advantage of the various techniques that have already been developed for that methodology. That is, this way is easier to design the multilevel secure schema than to develop a new model from scratch. This paper adds the security features 새? Object Model in the IDEA Methodology, and presents the transformation from this model to a multilevel secure object oriented schema. This schema will be the preliminary work which can be the general scheme for the automatic mapping to the various commercial multilevel secure database management system such as Informix-Online/Secure, Trusted ORACLE, and Sybase Secure SQL Server.

  • The purpose of this paper is to interpret the discourse on design thinking through the perspective of Roland Barthes' Mythologies. To this end, this paper will explore the mythologization process of design thinking using the methodological framework of Barthes, which structurally interprets the connotations produced using semiosis. Design thinking originally refers to a method which is used in the process of planning ideas about designs in order to create the final products for professional designs. However, design thinking has recently attracted more interest from the public because it has become known as a tool for solving various problems which exist outside of the field of design, such as social issues, management, and marketing strategies. Barthes points out that myths are used as a tool to deliver ideologies. He also emphasizes the importance of 'structural thinking'. It interprets the inherent connotative meanings more than the denotative meanings, which are explicitly shown. One of the most powerful ideologies which our society embraces today is creativity. Design thinking realizes the manifestation of creativity through a schematized process. This can be explained by considering design thinking as an icon that is specifically turned into a figuration to realize its objectness, in which a discourse for solving issues and social codes meet together and form a mythology. The mythologies that Barthes cites in his book refer to mythical values created by the cultural codes which humans have produced in our modern and contemporary age. The symbolic value of design thinking has become more important than the signifier which design thinking itself presents. This means that design thinking has become a sign that has mythical properties. In other words, the ideology of creativity embodied by design thinking has attained a mythological status, as it produces a new cultural code through innovation. The process of interpreting a phenomenon using the perspective of semiotics is an important tool that allows us to examine the concept of an object and its surroundings thoroughly. This paper attempts to expand the external scope of critical analysis about social phenomena by using the signs which continuously reveal themselves in common ideologies, such as design thinking, which has been gaining more popularity recently.

  • The purpose of this study is to verify the status of current digital comics research trends and the characteristics in Korea. For this purpose, 87 articles and dissertations published between 19900 to 2012 were analysed by a meta-analysis methods. Digital comics platforms, topics, methods were examined to understand the landscape of the digital comics in Korean context. The main results of this study are as follow. First of all, the number of researches on the digital comics has been in the rise, and the various academic journals have published articles to understand the digital comics on the basis of their own academic background. Despite of the short history of digital comics researches, the range of research subjects has been broaden, and more integrated approaches have been taken from the various research fields. The content of articles, however, was skewed to a certain platform, topic and the method such as the website based comics, the text analysis, and the qualitative methodology. Thus, the more systematic and integrated approaches are needed to understand the digital comics issues and to build up the digital comics studies.

  • The foundation of the development in modern typography is based on the era of International Typographical Style and Modern Typography that valued morphological functionality and rationality to achieve an accurate conveyance of meaning. However, with the advance of postmodernism, the view that the aesthetic and conceptual aspect must be included in its interpretation rather than its rational functionality was prominent. Indeed, the works of Dan Friedman and April Greiman, two graphic designers that are known to be the most representative of the post-modernistic era, displayed that graphic design works can also serve as a method for a more free artistic expression, unlike works of Modern Typography. This move towards aesthetic graphics was first started by Wolfgang Weingart. His various attempts at expanding the concept of typography had a significant impact on the development of New Wave and his experimentalist attitude brought about a ground-breaking change to the functional design and formative expression of modern typography. However, this thesis will consider the theoretical background of the typographical designs displayed in Wiengart's works and the experimental methods thereof, and will not attempt to evaluate Weingart's pioneering role and achievements. Furthermore, this thesis will shed new light on the argument that the Weingart's works are not based on the authorship view of post-modernistic typography and are rather utilized to expand the concept of typography based on a syntactical approach.

  • Component-based software engineering (CBSE) composes reusable components and develops applications with the components. CBSE is admitted to be a new paradigm that reduces the costs and times to develop software systems. The high quality of component designs can be assured if the consistency and correctness among the elements of a component are verified with formal specifications. Current formal languages for components include only some parts of contracts between interfaces, structural aspects and behavioral aspects of component, component-based system, component composition and variability. Therefore, it is not adequate to use current formal languages in all steps of a component design process. In this paper, we suggest a formal language to specify component designs Component-Z. Component-Z extends Object-Z, adds new notations to specify components. It can be possible to specify interfaces, the inner structure of a component, inner workflows, and workflows among interfaces with Component-Z. In addition, Component-Z provides the notations and semantics to specify variability with variation points, variants and required interfaces. The relation between interfaces and components is defined with mapping schemas. Parallel operator is used to specify component composition. It can be possible to describe deployed components with the specifications of component-based systems. Therefore, the formal specification language proposed in this paper can represent all elements to design components. In the case study, we specify an account management system in a bank so that we show that Component-Z can be used in all steps of component design.

  • Luxury fashion brands, which have dominated the market of high-priced apparel, bags and shoes, are recently showing changes of stepping into the cosmetics market. The purpose of this study is to examine how luxury fashion brand identity is transferred to cosmetic brand while expanding into luxury cosmetic brand, and to analyze the plastic signs of cosmetic package design and to analyze visual identity through a semi-symbolic system. Therefore, in this study, we tried to analyze the visual semiotic analysis of the package design such as the cushion compact, the lip tint and the brand logo which appeared in the popular product line of the fashion luxury brand such as Yves Saint Laurent and Armani. As a result of the analysis, this study has identified the semantic qualities expressed by each plastic element through the visual semiotic analysis process of the cosmetic package of Yves Saint Laurent and Giorgio Armani. These traits were found to be used as visual signs to reveal the 'Classicism' identity pursued by Yves Saint Laurent and the 'Baroque' identity pursued by Armani. Based on the results of this study, this study finds that the brand identity as a fashion brand is not transferring to the visual identity of cosmetic brands in the case of Yves Saint Laurent. On the other hand, this study found that Armani uses visual communication strategies to effectively transfer the brand identity as a fashion brand to the visual identity of cosmetic brands. On these two different results, it is necessary to examine whether luxury fashion brands and also Korean fashion brands are expanding into the cosmetics market and how they can better grasp the existing brand identity and apply it to the communication strategies of cosmetics brands.

A Study on Ideological Orientation and the Construction of News about Korean News Media : Focused on a Semantic Network Analysis for Articles about 'Bernie Sanders' (국내 언론매체의 이념성향과 뉴스구성에 대한 연구 : 미 대선 후보 '버니 샌더스' 관련 보도의 의미연결망 분석을 중심으로)

  • This study utilized a semantic network analysis for Korean major newspaper articles concerning 'Bernie Sanders'. 'Bernie Sanders' promotes conservative values of 'Americana' as well as the progressive values of 'relieving inequality', and thus, perhaps he is a subject on which ideological differences between the press can be distinctively manifest. Upon comparison of the priority of frequency between the conservative press and progressive press, the conservative press frequently used the expressions, 'socialist' and 'black man', whereas the progressive press frequently used the expressions, 'inequality' and 'problem'. Both the conservative press and progressive press displayed particularly different semantic compositions with the term, 'Korea'. The progressive press aimed to express the criticism of social problems and established politics identified by Sanders in relation to the 'Korean' society, whereas the conservative press criticized the blunt expressions stating that a specifically named politician resembles Sanders, and the specific party and term of 'Korea'. A completely different disposition of reports from different perspectives and context was ascertained, regardless of the use of the same terms. Thus, it is demonstrated that the semantic composition of the press on a specific issue displays significant differences according to their ideological disposition.
