  • Artificial intelligence (AI) is making computer systems intelligent to do right thing. The AI is used today in a variety of fields, such as journalism, medical, industry as well as entertainment. The impact of AI is becoming larger day after day. In general, the AI system has to lead the optimal decision under uncertainty. But it is difficult for the AI system can derive the best conclusion. In addition, we have a trouble to represent the intelligent capacity of AI in numeric values. Statistics has the ability to quantify the uncertainty by two approaches of frequentist and Bayesian. So in this paper, we propose a methodology of the connection between statistics and AI efficiently. We compute a fixed value for estimating the population parameter using the frequentist learning. Also we find a probability distribution to estimate the parameter of conceptual population using Bayesian learning. To show how our proposed research could be applied to practical domain, we collect the patent big data related to Apple company, and we make the AI more intelligent to understand Apple's technology.

  • Having an understanding of the properties of cytokines is essential for the immunologist, the researcher and the medical practitioner who need to understand immunologic diseases and immunological therapeutic approaches. Cytokines are redundant in their actions on target cells and promiscuous in their receptor reactions. (ED note: That is some cool use of English!) Moreover, many cells concomitantly produce several cytokines that have overlapping actions. Here this review provides conceptual framework to understand the intriguing aspects of the cytokine system.

  • Metadata and folksonomy are two main approaches in representing, organizing, and retrieving resources in the current information environment. Many researches have conducted studies to combine of metadata and folksonomy in order to utilize the strengths of both approaches. This research proposed an approach to utilize both metadata and folksonomy in representing resources by using microcontents. Microcontents in this research is a conceptual structure that reflects dynamic characteristics of folksonomy and the structure of metadata. By connecting folksonomy with metadata through this microcontents structure, both approaches can maximize their strengths and minimize their weaknesses in representing, organizing, and retrieving resources.

  • In the current information environment, many approaches have been adopted to represent and organize information resources. Among these approaches, folksonomy using tags is now being used in knowledge representation and organization. Although it may be an efficient approach to overcome the limitations of previous approaches, there are several problems in assigning tags such as ambiguity, inconsistency, and polysemy that limit efficient information organization. This research proposes a conceptual framework for the control of semantics of tags through linking up with bibliographic records in order to maximize the efficiency and minimize the limitations of folksonomy tags.

  • As today's cultural environment entered the information society, one of the biggest trends of future is the interests of nationalism. The purpose of this study is to interpret interrelation between sign and space design and analyze Korean contemporary space how to universalize traditional conception and attitude in design. The process of this study is illustrated as follows: At first, this study contains basic concepts and theories of semiotics and discusses the possibilities of semiotic approaches in spatial designs. Since the most outspoken theorist in this field can be found in writings of C.S. Peirce, American philosopher, the theoretical basis for this research Is taken from the Peirce's Semiotics. Secondly, this research tries the conceptual approaches based on traditional thoughts of Koreans formed with the philosophic background occurred with the universe, religion and the nature. And then, it approaches for the typical characteristics of Korean traditional space to interpret the meaning and adopt the triadic structure of sign. The structure is classified in status, icon, index, and symbol to analyze the Korean contemporary space design. Finally, it examines the expression structure of the nature of Korea that is succeeded in contemporary space design as the semiotic analysis of the application examples ; and studies the examples that try to set and solve the concept of space in modern society as the real issues in our cultural situations.

  • The purpose of this study is to define the concept of community based on the residential area and to review the issues on the research of community in related discipline area. The discourse about community has been developed in the field of social psychology, regional planning and architecture, housing studies, and research results by NGO. These studies of community has been dealt with social interaction and norm as well as the physical aspects of community. The research on community has been studied with the approach of structure and functionalist, systems theory approach, conflict theory approach, ecological approach, microsociological approach, and social construction approach. However, these approaches have not integrated together, but recognized community in a social or personal context. The social construction approach among these approaches suggest a useful conceptual framework for studying community in the point of view that social condition changes according to the autonomic individual. Understanding of community will influence to establishing a community norm, to planning a communal space, and to developing strategies of community. And it also takes a Important role t\ulcorner change the housing policy, institution and life style.

  • Logic and intuition are considered as the opposite extremes of teaching geometry, and any teaching method of geometry is to be placed between these extremes. The purpose of this study is to identify the characteristics of logical and intuitive approaches for teaching geometry and to derive didactical implications by taking Euclid's Elements and Clairaut's Elements respectively representing the extremes. To this end, comparing the composition and contents of each book, we analyze which propositions Clairaut chose from Euclid's Elements, how their approaches differ in definitions, proofs, and geometrical constructions, and what unique approaches Clairaut took. The results reveal that Clairaut mainly chose propositions from Euclid's books 1, 3, 6, 11, and 12 to provide the contexts that show why such ideas were needed, rather than the sudden appearance of abstract and formal propositions, and omitted or modified the process of justification according to learners' levels. These propose a variety of intuitive strategies in line with trends of teaching geometry towards emphasis on conceptual understanding and different levels of justification. Specifically, such as the general principle of similarity and the infinite geometric approach shown in Clairaut's Elements, we could confirm that intuition-based geometry does not necessarily aim for tasks with low cognitive demand, but must be taught in a way that learners can understand.

  • This study aimed to establish a conceptual scheme of the quality of university and to develop a set of structured indicators for assessing the quality of university based on the result of comparative analysis of major approaches in foreign countries. Reviewing extensive literatures regarding the quality of higher education, a conceptual scheme of the quality of university, in which three representative approaches such as a goal-accomplishment approach, a customer-satisfaction approach, and a value-added approach were emphasized, was proposed and the quality of university was defined as a function of harmonization of input-process-output elements of universities. To develop indicators for assessing the quality of university, four types of approaches including university accreditation system, commercially-producted university ranking system, college student survey, and direct assessment of students' learning outcomes were reviewed. Finally thirteen sets of evaluation indicators out of six countries were comparatively analyzed. The analyses focused on the format, the content, and the primary concept of the quality in each instrument and a draft of the assessment indicators were structured. The draft of the assessment indicators were verified through a panel of professionals. The final indicators assessing the quality of university consist of three dimensions and seven areas. The input dimension comprised institutional goals, human resources, and physical resources. In the process dimension, curriculum and learning process areas were included. And, finally, the output dimension consists of educational outputs and research outputs. Based on the outcomes of the study, the recommendations were suggested for improving and utilizing the assessment indicators of the quality of university.

  • This study aims to examine genetics problem-solving processes of high school students with different learning approaches. Two second graders in high school participated in a task that required solving the complicated pedigree problem. The participants had similar academic achievements in life science but one had a deep learning approach while the other had a surface learning approach. In order to analyze in depth the students' problem-solving processes, each student's problem-solving process was video-recorded, and each student conducted a think-aloud interview after solving the problem. Although students showed similar errors at the first trial in solving the problem, they showed different problem-solving process at the last trial. Student A who had a deep learning approach voluntarily solved the problem three times and demonstrated correct conceptual framing to the three constraints using rule-based reasoning in the last trial. Student A monitored the consistency between the data and her own pedigree, and reflected the problem-solving process in the check phase of the last trial in solving the problem. Student A's problem-solving process in the third trial resembled a successful problem-solving algorithm. However, student B who had a surface learning approach, involuntarily repeated solving the problem twice, and focused and used only part of the data due to her goal-oriented attitude to solve the problem in seeking for answers. Student B showed incorrect conceptual framing by memory-bank or arbitrary reasoning, and maintained her incorrect conceptual framing to the constraints in two problem-solving processes. These findings can help in understanding the problem-solving processes of students who have different learning approaches, allowing teachers to better support students with difficulties in accessing genetics problems.
