An Enterprise Architecture (EA) Framework is a tool which supports implementation of the Enterprise architecture that is used to enhance the interoperability of the IT components. In this paper, we propose a framework named as ENAE (ENterprise Architecture Framework) which combines enterprise architecture unit (AU), reference model, and association relationship between domain model. Architecture Unit is defined as a minimum set of a business process and its associated components such as application system and technical components. An EA can be designed and implemented by the aggregating the related AUs including association relationship between Architecture Units. Because UML model has limitations to describe business domain semantics because it is designed for general purpose, we adapt the DSM (Domain Specific Modeling) concept. We describe association relationship between Architecture Units designed by Domain Specific Modeling through Topic Map. Session 2 describes related works about Enterprise Architecture frameworks, Domain Specific Modeling, and Topic Map, while Session 3 explains components of the ENAF. Finally Session 4 shows the case study for implementation of the new Framework called ENAF.

Purpose In this paper, we propose the method to extend topic modeling techniques in order to derive data-based research hypotheses when establishing research hypotheses for social sciences, As a concept in contrast to the existing deductive hypothesis establishment methodology for the social science research, the topic modeling technique was expanded to enable the so-called inductive hypothesis establishment methodology, and an analysis case of the Seongsan Ilchulbong online review based on the proposed methodology was presented. Design/methodology/approach In this paper, an extension architecture and extension algorithm in the form of extending the existing topic modeling were proposed. The extended architecture and algorithm include data processing method based on topic ratio in document, correlation analysis and regression analysis of processed data for topics derived by existing topic modeling. In addition, in this paper, an analysis case of the online review of Seongsan Ilchulbong Peak was presented by applying the extended topic modeling algorithm. An exploratory analysis was performed on the Seongsan Ilchulbong online reviews through the basic text analysis. The data was transformed into 5-point scale to enable correlation and regression analysis based on the topic ratio in each online review. A regression analysis was performed using the derived topics as the independent variable and the review rating as the dependent variable, and hypotheses could be derived based on this, which enable the so-called inductive hypothesis establishment. Findings This paper is meaningful in that it confirmed the possibility of deriving a causal model and setting an inductive hypothesis through an extended analysis of topic modeling.

Korean healing research has developed over the past 20 years along with the growing social interest in healing. The field of healing research is diverse and includes legislated natural-based healing. In this study, abstracts of 2,202 academic journals, master's, and doctoral dissertations published in KCI and RISS were collected and analyzed. As for the research method, LDA topic modeling used to classify research topics, and time-series publication trends were examined. As a result of the study, it identified that the topic of Korean healing research was connected with 5 types and 4 mediators. The five were "Healing Tourism," "Mind and Art Healing," "Forest Therapy," "Healing Space," and "Youth Restoration and Healing," and the four mediators were "Forest," "Nature," "Culture", and "Education". In addition, only legalized healing studies extracted from Korean healing research and the topics were analyzed. As a result, legalized healing research classified into four. The four types were "Healing Spatial Environment Plan", "Healing Therapy Experiment", "Agricultural Education Experiential Healing", and "Healing Tourism Factor". Forest Therapy, which has the largest amount of research in legalized healing, Agro Healing and Garden Healing which operate similar programs through plants, and Marine Healing using marine resources also analyzed. As a result, topics that show the unique characteristics of individual healing studies and topics that are considered universal in all healing studies derived. This study is significant in that it identified the overall trend of research on Korean healing facilities and programs by utilizing LDA topic modeling.

Content is often developed inconsistently in technical authoring environments, as new documents are created and existing documents are revised. The Darwin Information Typing Architecture(DITA) is an XML-based, end-to-end architecture for authoring, producing, and delivering technical documentations. The core of most advanced authoring and publishing systems is the concept of content reuse. In this paper, we describe to design and implement an authoring and producing system of different technical documentations for the accreditation programs of Engineering Education using DITA XML. It provide a content reuse method for accomplishing the improvement of content consistency and the speed-up of the production in technical documentations.

Parks became essential to people after the introduction of modern parks in Korea. Following mayoral elections by popular vote, issues surrounding parks, such as the creation of parks, have arisen and have been publicized by the media, allowing for the formation of discourse. Accordingly, this study conducted a topic analysis by collecting news articles from major media outlets in Korea that addressed issues related to parks since 1995, after the introduction of mayoral elections by popular vote, and analyzed changes over time in the discourse on parks through semantic network analysis. As a result of a Latent Dirichlet allocation topic modeling analysis, the following five topics were classified: urban park expansion (Topic 1), historical and cultural parks (Topic 2), use programs (Topic 3), zoo event (Topic 4), and conflicts in the park creation process (Topic 5). The park-related discourse addressed by the media is as follows. First, the creation process and conflicts regarding the quantitative expansion of parks are treated as the central discourse. Second, the names of parks appear as keywords every time a new park is created, and they are mentioned continuously from then on, thereby playing an important role in the formation of discourse. Third, 'residents' form discourse about the public nature of the park as the principal agent in park-related media. This study has significance in that it examines how parks are interpreted and how discourse is formed and changed by the media. It is expected that discourse on parks will be addressed from various perspectives in further research focusing on other media, such as regional and specialized magazines.

In this study, the characteristics of rural tourism image perceived by urban residents were analyzed through text analysis of blog data. In order to examine the images related to rural tourism, blog data written with the keyword "Gochang-gun travel" was used. LDA topic analysis, one of the text mining techniques, was used for the analysis. In the tourism image of Gochang-gun, 9 topics were derived, and 112 major places appeared. This was divided into 3 main activities and 5 object spaces through the review of keywords and the original text of blog data. As a result of the analysis, the traditional main resources of the region, Seonun mountain, Seonun temple, and Gochang-eup fortress, formed topic. On the other hand, world heritage such as dolmen and Ungok wetland did not appear as topic. In particular, the farms operated by the private sector form individual topics, and the theme farm can be seen as an important resource for tourism in Gochang-gun. Also, through the distribution of place keywords, it was possible to understand the characteristics of travel by region and the usage behavior of visitors. In the case of Gochang-gun, there was a phenomenon in which visitors were biased by region. This seems to be the result of Gochang-gun seeking to vitalize local tourism focusing on natural, ecological, and scenic resources. It is necessary to establish a plan for balanced regional development and develop other types of tourism resources. This study is different in that it identified the types and characteristics of rural tourism images in the region perceived by visitors, and the status of tourism at the regional level.

For the past half century, the Journal of the Korean Landscape Architecture has been leading the landscape architecture research and industry inclusively. In this study, abstracts of 1,802 articles were collected and analyzed with topic modeling and network analysis method. As a result of this paper, a total of 27 types of subjects were identified. Health and healing in the field of environmental psychology, garden and aesthetics, participation and community, modernity, place and placenness, microclimate, tourism and social equity also have been continued as important research area in this journal. Modernity, community and urban regeneration is hot topics and ecological landscape related topics were cold topics. Although there was a difference by subject, the variability of the research subjects appeared after the 2000s. In Network analysis, it shows that 'Park' is a representative keyword that can symbolize the journal, and 'landscape' is also important a leading area of the journal. Looking at the overall structure of the network, it can be seen that the journal conducts research on 'utilizing', 'using', and creating 'park', 'landscape', and 'space'. This study is meaningful in that it grasped the overall research trend of the journal by using topic modeling and network analysis of text mining.

This study attempts to identify the flow of key topics and issues of research trends related to environment-friendly agriculture conducted around the 2000s in South Korea and compare them with the environment-friendly agriculture promotion plan to seek the level of consistency and the direction of future development of environment-friendly agriculture. For the analysis of environment-friendly agriculture research trends and policy consistency, 'topic modeling', which is suitable for subject classification of large amounts of unstructured data, and 'text network analysis', which visualizes the relationship between keywords as a network and interprets its characteristics, were utilized. Overall, active discussions were held on 'technical discussions for the production and cultivation of environment-friendly agricultural products' and 'food safety & consumer awareness', and keywords such as production, cultivation, consumption, and safety were consistently linked to other keywords regardless of time. In addition, it was found that the issue of environment-friendly agriculture was partially consistent with the policy direction of the period. Considering the fact that the ongoing '5th Environment-Friendly Agriculture Promotion Phase' emphasizes the strengthening of rural environment management and aims to ensure the continuous quantitative and qualitative development of environment-friendly agriculture, active discussions and research on its environmental contributions and management methods are needed.

As a result of imminent recognition on nature from modern world, the need for the combination between architecture and nature has been raised as another topic in architectural arena, and this kind of work is being conducted under the notion of Landscape. As the term 'Landscape' emerges as the key word in contemporary architecture, 'Landscape' begins to transcend the mere meaning of landscape architecture(gardening). The word, Landscape, has gone beyond the meaning of mere landscape, or rural vista one-dimensionally, and, after having introduced the attributes of nature into building activities, has emerged as a notion trying to form 'the architecture as landscape.' Together with these, 'Landscape' is expanding as a notion having various layers. The notion's, 'Landscape', occupying the significant position in contemporary architecture has been a recent phenomenon over 1980-1990s, and its category of practice has not certain limitation, rather it has started simultaneously from various areas. This study, before reviewing the architectural notion of Landscape by studying the Landscape notion and its various embodying methods being shown in contemporary architecture. As a result of examining the features of Landscape notion shown in various directions(ways), being influenced by the four Landscape types presented by Eduard Bru and the currents of the times, we can see that, though the features are somewhat similar, they are classified and explained as different types respectively. So, we are able to recategorize the features into 6 domains in this study.

Architecture should deviate from euclidean ideas of abstract space while helping to accommodate individual perceptions and experiences of a given space. Concepts for making space should be cognitively processed. The process of gathering information from the environment represents a new spatial concept as expressed in the cognitive structural relationship between the environment and the individual as the subject of architecture. Additionally, the cognitive experience of space is primarily perceived visually, and visual perception is the basis for information-gathering and decision-making. Therefore architecture should be excluded from the conceptual focus on the existing space design rules, being expressed instead in experimental architectural spaces connected to subjective human experience. While some research has been done on this topic regarding architecture, further study is required in the area of interior design. This study proposes the possibility of composing effective living space through an investigation of cognitive space concept theory and expression elements, and includes a case study of Interior architectural spatial analysis.
