  • A systematic classification of Korean traditional patterns has been made according to their objects and presenting methods. The classification is represented with 3 levels of categories. First, the superordinate category is composed of 7 groups of patterns, i.e. Naturals, Animals, Plants, Artifacts, Geometric, Composites, and Others. Second, the basic category is composed of motifs in each group. Third, the subordinate category is composed of 3 types, i.e. realistic, stylized, abstracted, according to the degree of simplification. As this classification is a method for organizing informations in Korean traditional patterns in a systematic way, it can offer a useful basis for computerization of the patterns.

  • With the development of information and communications technology (ICT) and big data technology, anyone can easily obtain and utilize vast amounts of data through the Internet. Therefore, the capability of selecting high-quality data from a large amount of information is becoming more important than the capability of just collecting them. This trend continues in academia; literature reviews, such as systematic and non-systematic reviews, have been conducted in various research fields to construct a healthy knowledge structure by selecting high-quality research from accumulated research materials. Meanwhile, after the COVID-19 pandemic, remote healthcare services, which have not been agreed upon, are allowed to a limited extent, and new healthcare services such as health recommender systems (HRS) equipped with artificial intelligence (AI) and big data technologies are in the spotlight. Although, in practice, HRS are considered one of the most important technologies to lead the future healthcare industry, literature review on HRS is relatively rare compared to other fields. In addition, although HRS are fields of convergence with a strong interdisciplinary nature, prior literature review studies have mainly applied either systematic or non-systematic review methods; hence, there are limitations in analyzing interactions or dynamic relationships with other research fields. Therefore, in this study, the overall network structure of HRS and surrounding research fields were identified using citation network analysis (CNA). Additionally, in this process, in order to address the problem that the latest papers are underestimated in their citation relationships, the GraphSAGE algorithm was applied. As a result, this study identified 'recommender system', 'wireless & IoT', 'computer vision', and 'text mining' as increasingly important research fields related to HRS research, and confirmed that 'personalization' and 'privacy' are emerging issues in HRS research. The study findings would provide both academic and practical insights into identifying the structure of the HRS research community, examining related research trends, and designing future HRS research directions.

  • This paper makes an attempt to find a systematic portion of the database design process, especially using the Entity-Relationship(E-R) model. Basically, we consider three aspects as a systematic portion of the database design process. They are, the strategy that a designer selects to design an E-R diagram, designer's cognitive style, and the knowledge and preference of the database designer. An experiment has been carried out in order to verify the systematic relationship between above-mentioned three aspects and the E-R modeling performance. The target system is a professional baseball system. A normative E-R diagram was constructed based upon 48 E-R diagrams produced during the experiment. The ANOVA process has been used to analyze the results. It has been found that there exist significant differences in query-answering capacity and the completeness of the E-R model among design methods. Individual differences in cognitive styles has not been found to be significantly related to the modeling performance.

  • Although it is not easy to generate EC's (Engineering Characteristics), there have been few studies so far. In this paper, a systematic method for generating EC candidates is proposed. This method use the concept of 'attribute listing'. In the proposed method, customer attributes are divided into their objects and issues. And attributes from their objects and issues are generated by help of guidelines proposed, respectively. Then, measurable metrics are attained from those attributes. Finally, the metrics result in EC candidates by consistency and redundancy check. This paper gives an illustrative example for easy comprehension of the proposed method.

  • The research objective of this thesis aims to utilize the history and culture of cities as resources and to solve the problems of modern urban environment which can produce non-personality in the age of globalization. This study deals the Sustainable Urbanism and Architectural System in the Historical city ; First, Historic resources and its spatial characteristics. Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders. In order to keep the order, rehabilitation, reuse, remodeling of urban space should be managed by various participations which concerned with the city and urban architecture. That can be say systematic approach for the sustainable environment.

  • Advancement of Web technology has increased the number of web site and user population. Businesses develop Web applications as its core applications to support business transaction though Internet Although a systematic development methodology should be used to develop Web applications, most businesses do not follow a systematic approach. This study shows a systematic development approach for Web-based electronic commerce information systems. Specifically, it shows how to design a conceptual model following a hypermedia application development model RMM(Relationship Management Methodology) and develop a logical database represented in an XML(extensible Markup

  • The results and suggestions for this study is as follows: First, as the education for business ethics is instructed, the level of recognition for business ethics is intensified. Second, the result after verifying the hypothesis shows a meaningful difference between utilitarianism and the principle of justice. Third, it is necessary for us to teach the business ethics using a systematic education program over a long period. Fourth, business ethics education should be taught in colleges as well as in the home and community. The limitations of this study and the directions of following studies is as follows: Frist, in spite of establishing a research model concerning business ethics, the researcher could not develop a systematic education program for business ethics. Second, it is necessary to develop a systematic education program for business ethics in order to utilize it for producing practical study. Finally, it is necessary to develop some evaluation tools for relativism.

  • This systematic review compared Korean and international researches on sensory integration therapy in patients with autism spectrum disorder (ASD). We targeted studies on sensory integration therapy for patients with ASD published from January 2000 through July 2016. Specifically, we analyzed the papers that used the phrase 'sensory integration, autism' as keywords. There were fewer Korean studies of sensory integration therapy, and the diversity of research topics were limited, focusing mainly on case studies. There was no difference between the internal/external validity of Korean and those of international studies targeting the clinical environment and patients. Further study of a variety of aspects of sensory integration therapy is needed to gain high internal/external validity.
