As the change of information and digital technology progresses, ubiquitous space is attracting attention as a new space concept in which the physical and digital spaces are connected to each other. As its meaning in latin itself - 'there exist everywhere at the same time'- implies, however, the ubiquitous space has been mostly discussed in a non-physical aspect, such as in a technological area, rather than its physical intrinsic property until now. Although theories regarding a ubiquitous city have been rarity suggested, in most cases, technological aspects such as the systemization or networking of individual information service have been the focus. However, one of the intentions induced in the concept that scholars including Mark weiser and Sakamura Ken introduced was to place humans in the center of the space in which the technology has been placed instead of humans. For this purpose, the renovation of human interface must be required. As technology develops, the achievement of ubiquitous space may be possible, and efforts to apply this to real space are making an appearance. The examples of the present research are the spaces that have a characteristic of the laboratory separated from life in the city, and the construct scale is in the level of an individual facility; therefore, further studies should functionally and spaciously connect all subjects existing in space and effectively relate this to real world. The present research is intended to demonstrate the investigation on several projects that are currently underway and the developmental direction of new, ubiquitous space.

Users who want to experience the metaverse for tourism are exposed to strategic planning in space for the purpose of cultural content. In addition, users learn integrated cultural content in the process of proceeding according to the virtual environment. and Along with the meaning of time and space, users will experience space-telling. It is important to induce interest from the beginning of the experience to continue the experience. However, obstacles arise in this process. This is because developers should promote connections with new information to users who do not have sufficient prior knowledge and only have keywords of interest. Therefore, efficient design methods to enhance interest should be studied in advance. But so far, there has been no research on how to systematically design prior organizers to induce interest in virtual space. This study is an interest-inducing design method that occurs in the process of developing the meaning of virtual space and storytelling of cultural content, and can be seen as a basic study using conceptual guidance-based prior organizer education and learning techniques. First, virtual space elements and human behavior theories were considered. Subsequently, five representative examples of previous organizers currently used were explored, and redesigned and proposed based on a conceptual map for information access and delivery purposes. Through this research process, it was possible to confirm that spatial attributes and cognitive interest elements were effectively transmitted to meaningful learning leading to storytelling learning and elements of service design design method through conceptual guidance.

This study is intended to look into the effect of dining space color and design on customers' psychological response, satisfaction, and reuse intention of restaurants. To achieve this, an empirical survey was carried out based on responses from 400 dining-out customers. The results were as follows. The dining space color and design had a significant and positive effect on customers' psychological reaction, satisfaction and reuse intention of restaurants. This is a result of positively evaluated service through an increased customer emotional response to simultaneous factors. It also suggest a recognition of a customer's psychological response in forming images based on restaurant attributes aside from food quality, such technique, ornamental equipment, sound, and design factors harmonized with indoor environment, in an attempt to increase customer interest in an increasingly competitive business environment. Consequently, dining space color and design can lead to customers' psychological satisfaction and reuse intention.

Empathy is the ability to feel, understand, and respond to the emotions of others from the standpoint of others. Recently, 'sympathy' has emerged as an important issue not only in emotional empathy in relation to individuals but also in 'social empathy', which sees sympathy as a basic principle for maintaining society. This study focuses on the issue of empathy as a new driving force for modern society and focused on 'urban scene' as a spatial application for cultural empathy in the city. Urban scenes approach the city as a space of consumption, classify it according to its inherent attributes, and analyze its characteristics. This study approaches the existing urban scene theory in terms of empathy. In addition, as a way to consume city images reflected on contents, a concrete example of 'contents tourism'is examined, and a 'contents scene' is proposed as a new urban scene and its meaning and possibility are presented.

새로운 것을 학습할 때 학생들은 자신이 어떤 지식 상태를 갖고 있는지에 따라 상당히 다른 이해의 정도를 나타낸다. 유의미한 이해를 이끌어 내기 위해서 교사들은 학생들의 사전 지식상태를 파악하고 그것에 근거하여 학습과제를 제시할 필요가 있으며, 어떤 단원을 학습한 후에 학생들의 지식상태를 파악해 보는 방법도 모색되어야 할 것이다. 본 연구는 충청북도 C도시 4개 초등학교 5학년 학생 285명에게 수학 5-가 6단원을 학습한 후 넓이 측정과 관련된 지식상태 검사를 실시하고 그 결과를 Doignon & Falmagne(1999)의 지식공간론을 활용하여 분석하였다. 학생들의 답안에서 평면도형의 넓이 측정과 관련된 지식의 상태를 파악하고 세 가지 범주-측정의 의미 파악, 공식 활용, 전략의 사용-에서 지식 상태의 위계도를 작성하였다. 첫 번째 범주인 측정의 의미 파악과 관련하여 학생들은 둘레나 넓이의 속성 파악에서 혼동을 보이거나 직관적으로 넓이를 비교해야 하는 과제에서도 계산을 시도하는 지식 상태가 반 이상인 것으로 드러났다. 두 번째 범주인 공식 활용과 관련해서는 학생들의 상당수가 부적합한 수치를 넣어 무조건 넓이 계산을 시도하고 있었다. 또한 세 번째 범주인 전략 사용에 관해서는 분할이나 등적변형 등의 전략을 알고 있는 학생 중에도 40% 가량은 문제를 표상하는데 어려움이 있어 해결하지 못하는 것으로 드러났다.

This study analyzes location based game focused on the figurative characteristics of mobility. The purpose of this analysis is to extend the understandings of game mobility from technical side toward rhetorical territory. Christian Metz's film theory is appropriate for analysis of the game which is visual and combinational text. According as research findings, structuralize 5-layered spatial maps. And this kind of multi-layering structure generates figurative operations. Adaptive mobility by metaphor, it reflects player's real world movement into the virtual space. Metonymy brings given mobility, it reflects character's movement through all of the virtual maps.

Datamining from the large data in the form of various techniques for obtaining information have been developed. In recent years one of the most sought areas of pattern recognition and machine learning method is created with most of existing learning algorithms based on categorical attributes to a rule or decision model. However, the real-world data, it may consist of numeric attributes in many cases. In addition it contains attributes with numerical values to the normal categorical attribute. In this case, therefore, it is required processes in order to use the data to learn an appropriate value for the type attribute. In this paper, the domain of the numeric attributes are divided into several segments using learning algorithm techniques of discritization. It is described Clustering with other data mining techniques. Large amount of first cluster with characteristics is similar records from the database into smaller groups that split multiple given finite patterns in the pattern space. It is close to each other of a set of patterns that together make up a bunch. Among the set without specifying a particular category in a given data by extracting a pattern. It will be described similar grouping of data clustering technique to classify the data.

Districting is a spatial decision making process to make a new regional framework for affecting human activities. Natural barriers such as rivers and mountains located within a reorganized district may reduce the efficiency of reorganized human activities. This implies that it is necessary to consider boundary characteristics in a districting process. The purpose of this research is to develop a new spatial optimization model based on boundary characteristics for districting problems. The boundary characteristics are evaluated as continuous value expressing the possibility of combining adjacent two basic spatial units rather than a dichotomous value with 1 or 0 and are defined as an objective function in the model. In addition, the model has explicitly formulated contiguity constraints as well as constraints enforcing demand balance among districts such as population and area. The boundary attributes are categorized into physical and relational characteristics. Suitability analysis is used to combine various variables related to each boundary characteristic and to evaluate the coupling possibility between two neighboring basic units. The model is applied to an administrative redistricting problem. The analytical results demonstrate that various boundary characteristics could be modeled in terms of mixed integer programming (MIP).
