본 논문에서는 이동 로봇의 유연하고 짧은 경로 계획을 위하여 기존의 그리드 셀(grid cell)로 구성되는 지도 대신에 삼각형을 이용하여 지도를 구성하는 새로운 방법을 제안한다. 기존의 그리드 셀로 구성되는 지도의 경우 이동 로봇가 현재 셀에서 다음 셀로 진행시 진행 방향이 8 방향이나, 본 논문에서 제안한 방법에 의해 구성된 새로운 지도는 셀을 삼각형으로 표현함으로써, 이동 로봇의 진행 방향이 12 방향이 된다. 이와 같이 이동 로봇의 진행 방향이 증가한다는 것은 이동 로봇이 더욱 유연하게 장애물을 회피하며 더욱 짧은 경로로 주행할 수 있는 가능성을 의미한다. 한편, 본 논문에서 제안한 삼각형 지도 작성 방법의 효율성을 기존의 그리드 셀을 이용한 경로 계획 알고리즘인 거리 변환(path transform) 경로 계획을 통하여 증명한다. 또한 새로운 삼각형 지도 구성이 메모리의 효율성 위해 이동 로봇의 주행 환경을 장애물이 비어있는 공간을 가능한 하나의 셀로 병합하는 4진트리 방법(quadtree method)에도 적용 가능함을 보인다.

Due to COVID-19, organizations are rapidly changing the way they work by providing telecommuting and flexible work, and by expanding Smart Work spaces. In a Smart Work situation, workers have improved their job autonomy to choose their work methods, hours, and places. However, previous studies do not reflect the Smart Work situation and there are limitations to still using the previous job autonomy concept and measurements. To overcome these problems, this study derived job autonomy types such as methods, scheduling, criteria, time, and place applicable to Smart Work environments and verified that the five types of job autonomy have a statistically significant positive effect on Smart Workers' creative behavior. This study is meaningful in that it categorized job autonomy into five types applicable to Smart Work by adding temporal and spatial flexibility to the traditional job autonomy concept such as method, scheduling, and criteria autonomy and provided the basis for subdividing and evaluating the operation performance of Smart Work through multi-dimensional job autonomy verification.

With the recent changes in society and the introduction of new technologies, the usage patterns of parks have become diverse, leading to increased complexity in park management. As a result, there is a growing demand for flexible and diverse park management that can adapt to these new requirements. However, there is inadequate discussion on these new demands and whether urban park management policies can respond. Therefore, empirical research on how park usage patterns are evolving is critical. To address this, blog data, in which individuals share their experiences, was used to examine the spatial consumption patterns through semantic network and topic analysis. This study also explored whether these spatial consumption patterns exhibit experiential consumption characteristics according to the experience economy theory. The results showed that consumption behaviors, such as renting picnic sets and having food and drinks delivered, were prominent and that emotional experiences were pursued. Furthermore, these findings were consistent with the experiential consumption characteristics of the experience economy theory. This suggests that park planning and maintenance methods need to become more flexible and diverse in response to the changing demands for park usage.

The named source kept in all place names alludes to the close relationship between place name and its place while it also becomes a fundamental condition for geographical research on place names. Meanwhile, the named source may be recognized differently according to who the social subjects producing and changing place names Life. Place names represent and constitute the identity and the ideology of the diverse social subjects. This aspect is related to cultural politics concerned with conflicts and contestation among different social subjects over the meaning of place names. Particularly, the Gongju-Mok Jingwan Area in the Korean peninsula has long history and geopolitical location as a borderland and a buffer zone. As a result, it has provided many conditions for cultural diversity and power relations, both of which have caused social subjects to contest their social power across space and time, and has led to produce the several types in the changes of place names. Therefore, this paper aims to investigate the types according to the named source, especially that of the forepart of place names morpheme, and those cultural-political meanings. These place names are classified into three large groups, such as the physical place names, the social place names, and the economic place names. These types of place names have represented the place identity and the ideology of diverse social subjects, and also accompanied the changes by power relations between themselves.

The implication of space in school libraries more important than the other types of libraries because their main user is students who are affected by service environment. Let me consider the reality of our circumstance, the space is not enough in the school library, Therefore, it is essential to utilize of library space effectively. So, this study intends to suggest effective organization model of school library space, through introduced by the notion of information commons. The results show that they are integrated within school library, which, in addition to other functions, may include recreation center, and interactive community, circulation space, administrative offices and so on and suggest the library space design and management need to reflect the flexibility and inter-activeness of the space. Also, in order to acquiring human-centered aspect and openness, school library appropriate space planning for present needs and future expansion is imperative within school community.

This study is concerned with analysing complexity, flexibility and dynamism of social discoursive space. The developmental process of social discourse is analogous to that of a spatial structure of social discourse. Post-capitalist society has seen New-Liberalism and New-Conservatism have become dominant, resulting in the deterioration of the cultural politics of citizenship. It is argued that the position of otherness, in which those binary structures (inside/outside or centre/margin) collide and collapse, is where subversive discourse can emerge to dominant discursive power. Furthermore, it is necessary to democratize social discursive space, through which the Other becomes able to. participate in the social production, distribution and consumption of social discourse.

This study aimed to empirically analyze the effect of the appreciation of artwork in the workplace on creativity. To this end, two virtual workspace images with and without artwork were created, and an online survey was conducted with office workers. A regression analysis was performed on the results to investigate whether and how much the appreciation and recognition of artwork was effective for the creativity. As a result, among the factors of recognition according to the appreciation of artwork, "intellectual development" and "thinking" showed positive effects on the five sub-factors of creativity at work, such as original flexibility, alternative problem-solving skills, pursuit of adventure and freedom, individual independence, and exploratory immersion. Unlike most previous studies, however, "understanding" had a negative effect on original flexibility. In conclusion, it was found that some of the factors of the appreciation and recognition of artwork had a positive effect on creativity at work. This study provides implications that the appreciation of artwork in the workplace is effective for improving creativity at work and that it is important for each company to develop a streamlined approach based on its goal of pursuing a creative environment. In addition, it is expected that this study will contribute to the widespread use of artwork sharing services at workplaces as well as encouraging more empirical studies to be done on the effect of the services.
