There are certain polemics regarding what kind of approach is most appropriate in the study of urban cluture. The tension seems to come from the misunderstanding of each other. A major source of the misunderstanding is different usage of the term 'culture' The lerm 'culture' may be interpreted either as way of life (fig. 1), system of meaning (fig. 2), the fourth structural condition (fig. 3), sophisticated taste (fig. 4), a superstructure of intellect and arts (fig. 5), biological supporting system (fig. 6), or all encompassing conditions (fig. 7). Whatever definition is taken for the term 'culture', there is a parallel definition of 'environment' for each stance (figures 1 - 7) What kind of definition is adopted matters because each of them is deeply rooted in different perspectives and focuses. It however, seems impossible to completely deny or disprove the utility of any of the slances. This, we may have to accept the diversity of definitions and consider urban cultural geography as a basket in which diverse concepts and perspectives are collected and nurtured.

In this study, we conducted to derive some implications by analyzing the computer education framework proposed by K12CS in the United States in order to organize the software curriculum and conceptualization of computational thinking in Korea. First, we discussed the use of the term Computational Thinking as a Computing Thinking in Korea and compare it with the concept presented in the US curriculum. we derived that Computing Thinking and Computational Thinking are different in the focus and scope of problem solving. Second, considering the fact that Korean software curriculum does not consider the hierarchy according to the school and the grade, we reconstructed the curriculum based on the core practices and concepts which were suggested by the organization of K-12 Computer Science in the United States.

All learners have to improve problem-solving abilities based on the principles of Computer Science and Computational Concepts as well as enhance their information technology fluency for living in the 21st century. However, there are no clear answers for fundamental questions such as 'What is Computer Science?' or 'What is the nature of Informatics education?'. Informatics education is threatened by the terminological confusion and misleading external images of Computer Science or Informatics education. Therefore, in this study, we closely reviewed perspectives on the nature and necessity of Informatics education and suggested a perspective to improve Informatics education. First, we examined how the definition of Computer Science has changed and pointed out that the Computer Science curriculum has operated differently from country to country because of the different viewpoints about Computer Science. Moreover, we presented evidence to assert that Informatics education should be considered as an independent science subject that is for all students. Finally, we suggested essential elements to insist that Informatics is a discipline to improve computational thinking. Essential elements consisted of 'Representations', 'Processes', 'Machines', 'Relationships' and 'Construction'. We suggested that the concept of Informatics should be extended based on these five elements.

The concepts of sample and sampling are central to make a statistically correct decision, so we need to be emphasized their importance in the statistics education. Nevertheless, there were not enough studies which discuss how to teach the concepts of sample and sampling. In this study, teaching sample and sampling is addressed by foreign curricula and cases of instruction in order to obtain suggestions for teaching sample and sampling. In particular, the curricular of Australia, New Zealand, England and the United States are analyzed, considering the sample representativeness and the sampling variability; the two elements in the concept of sample. Also foreign textbooks and cases of instruction when it comes to teach sample are analyzed. The results say that with respect to teach sample can be divided into four suggestions: first, sample was taught in the process of statistical inquiry such as data collection, analysis, and results. Second, sample was introduced earlier than Korea curriculum. Third, when it comes to teach sample, sample variability, as well as sample representativeness was considered. Fourth, technological tools were used to enhance understanding sample.

In this study, we identified the theoretical basis of management and planning of life-cycle, the core concept of resource "Administration and Independence," of Home Economics curriculum according to "Notification of Education Ministry #2015-74." First in relation to "management", we identified the systematic theory, the theoretical basis of traditional home management, and diagnosed how this systematic theory is reflected on 2015' curriculum. As a result, the contents of actual curriculum's middle school contents does not include integrally the life related problems that middle students are facing in real life, and it is hard to be convinced what priority the element of selected contents have of several problems. Next, in case of planning of life-cycle that accentuates the importance of life plan corresponding to career orientation it mentions the contents including very comprehensive area such as value, profession, health as well as developmental task, but the fact leaves to be desired that 2015 curriculum is overlooking the importance of financial planning, the international trend.

This study ultimately aims to suggest directions for development of U-City Competitiveness Index through thorough analyses of U-City competitiveness concepts and previous research in U-City-related index. In an attempt to reach the aforementioned goals, the concept of U-City competitiveness is presented based on existing publications on informatization age, future city, and U-City. Next, insights on the development of U-City Competitiveness Index are provided via analysis of research on indices regarding U-City and future city. Finally, the process of developing UCity Competitiveness Index and cautionary comments for each developmental step has been provided. Based on the research results, U-City competitiveness refers to the ability to respond to demands of residents in a timely manner as well as to manage U-City, ICT, U-City infrastructure, and U-City services that maximizes the efficiency of urban space management. In order for proper assessment of these criteria, development of assessment tools, selection of indices, standardization, allocation of weight per index, and construction of assessment framework are required.

Recently, diverse information which are location, call history, SMS history, photographs, and video can be collected constantly from mobile devices such as cellular phone, smart phone, and PDA. There are many researchers who study services for searching and abstraction of personal daily life with contextual information in mobile environment. In this paper, we introduce MyLifeBrowser which is developed in our previous work. Also, we explain LPS and correction of GPS coordinates as extensions of previous work and show LPS performance test and evaluate the performance of expanded keywords. MyLifeBrowser which provides searching personal information in mobile device and support of detecting related information according to a fragmentary keyword and common knowledge in ConceptNet. It supports the functionality of searching related locations using Bayesian network that is designed by the authors. In our experiment, we visualize real data through MyLifeBrowser and show the feasibility of LPS server and expanded keywords using both Bayesian network and ConceptNet.

The Fourth Sector has been attracting attention as a means to solve the various problems plaguing modern society; it emerged to overcome the Third Sector's issues such as excessive reliance on the government and service model isomorphism, represented by social economy enterprises (Meadows, 1972; Howaldt & Schwarz, 2010). Social venture companies have been mentioned as key agents of the Fourth Sector (Gyeonggi Research Institute, 2018). However, the academic and policy concepts related to social ventures continue to be vague. Therefore, this study aims to clarify the concept of social ventures as part of the Fourth Sector, and research development strategies for the vitalization of the social venture ecosystem in an effort to encourage inclusive growth of society. To achieve these goals, it establishes the concept of social ventures differentiated from the Third Sector, based on previous studies, and presents the importance of an intermediate support organization for the ecosystem's vitalization. Furthermore, to propose strategies for said vitalization, the study derives detailed forms of social venture intermediate support organizations, and provides suggestions regarding their importance and roles through social innovation levels.

Acoustic Quanta, which British Physicist Dennis Gabor created, is the theoretical background for granular synthesis and has influenced many computer music artists and sound designers. Acoustic Quanta is a very short sound burst, lasting only 1 to 100 ms. Granular synthesis is a sound synthesis technique which slices original sound into sound grains and re-combines them into a new acoustic event. Concept of sound grain is borrowed from the acoustic quanta. Granular Synthesis can make very unique sound, so that it can be useful in many ways, especially in sound design. This paper presents concept of acoustic quanta and granular synthesis. It then discusses making a synthesizer as an implementation of synchronous granular synthesis and its applications on sound design. As a result, the duration of acoustic quanta should range between 0.239 and 33.367 ms, in consideration of audible frequencies, which is different from the original concept of the acoustic quanta.
