  • Recently, mean shift tracking algorithms have been proposed which use the information of color histogram together with some spatial information provided by the kernel. In spite of their fast speed, the algorithms are suffer from an inherent instability problem which is due to the use of an isotropic kernel for spatiality and the use of the Bhattacharyya coefficient as a similarity function. In this paper, we analyze how the kernel and the Bhattacharyya coefficient can arouse the instability problem. Based on the analysis, we propose a novel tracking scheme that uses a new representation of the location of the target which is constrained by the color, the area, and the spatiality information of the target in a more stable way than the mean shift algorithm. With this representation, the target localization in the next frame can be achieved by one step computation, which makes the tracking stable, even in difficult situations such as low-rate-frame environment, and partial occlusion.

  • Place matters to knowledge creation according to the recent literature on economic geography and its related disciplines. This basic insight is not incorrect. But there is some vagueness in the discussions on this theme and there seems to appear a variety of geo-determinism on the competitiveness of SMEs in manufacturing industries. This paper reexamines that thinking on the basis of the realities of innovative manufacturing SMEs in a periphery of Japan, south of Kyushu Island. As a result, it is possible to classify face-to-face contacts into two kinds of communication. One is the communication, through which a supplier of a way of solution (knowledge) can grasp problems (information) of its customer in detail. The other is the communication, through which one can get some new idea. Information can spread world wide, but not always quickly and ubiquitously, because it often contains tacitness and secret, even if a large part of the information are coded in some form. Details of the information can be communicated only with the help of five senses. And it is necessary for the information receiver to listen to the sender carefully with the help of the other senses. In this meaning, tacitness does matter. Knowledge, namely ability to understand and power to bring some idea in practice, is always connected with some place, either at workshop of supplier or of customer in the case of manufacturing industries. However, not places but human beings possess the knowledge, and human beings can be mobile. Therefore, it is not restricted to a place.

  • This study calculated the NDVI and the NDBI of the land-use change in major cities at North Korea through Landsat imagery, and analyzed the spatiality(LISA) with difference discretization of the UI index. As a result of the research, we could identify that the degree of urbanization has been increased in both Gaesung and Pyeongyang, but showed opposite spatial tendency to each other. The urban index of Pyeongyang, a nucleus district of North Korea, has been progressed quicker than Gaesung since 1994, while the urbanization development was being progressed also in general, as it expanded from the existing downtown area. On the other hand, the urbanization took place intensively at one region in Gaesung by developing the vegetation area that forest transfers into a built-up area, which has been judged from the great dynamic range of NDVI values. In conclusion, it is possible to extract necessary data for understanding the degree of urbanization and spatial characteristics of North Korea through the UI and the LISA analysis that are considered to propose useful methodology in investigating changes in North Korean cities and political levearage.

  • The aim of this study is to reveal the lived experience of gambling addicts who have chosen to move near to a casino area to live. Thus, the researchers interviewed four gambling addicts (who live in the vicinity of the casino)and analyzed what spatiality they experienced and what it meant by using the van Mannen's hermeneutics phenomenological approach. The result revealed that what affected and constituted their lived experiences essentially was not where they came from or where there are now but the phenomenon itself which they stayed close to the casino. Even though they escaped their own living space for themselves and flowed into the casino vicinity, they seemed to live only for today, however they lived to make up the past loss or dream for better future through beating the odds of gambling. Therefore they did not make an ontological living. Thus, they were experiencing an existential anxiety as a 'Sandwich Being' between the outside world and somewhere else in the world.

  • Smart agriculture has emerged to be a solution to the global food crisis and a new growth engine in the era of the Fourth Industrial Revolution. The purpose of this study is to reveal the spatiality of smart agriculture by analyzing smart agriculture policies in major countries and examining how major's agricultural knowledge and experience are expressed in specific agricultural environment. I selected China, Japan, the Netherlands, and the United States as representative examples. In the analysis of agricultural policy, the direction, governance and main areas and technologies were focused. As a result, it is found both standardization strategy and the localization strategy work at the same time. Standardization strategies decontextualize technologies and policies from the economic, social, cultural, and ecological contexts of region. The regionalization strategy builds a smart agricultural model for each country with reflecting geographical characteristics. This study could be for facilitating further researches on geographies of agricultural technology and agricultural knowledge production.

  • 보안등은 주택가 골목에 안전을 위해 설치하는 중요한 설비로서, 도로 폭이 12m 이하인 장소에 설치된다. 그러내 통행 인구가 없어도 야간시간 내내 점등되고 있기에 낭비되는 전력량이 상당하다. 적외선센서가 부착된 보안등을 교체하게 되면 보행자의 움직임을 통해 일정시간 점등이 되고 이동체가 없을 때는 소등이 되어 전기에너지의 소비를 상당히 줄일 수가 있어 온실가스저감에 기여할 수 있다. 본 논문에서는 적외선센서 보안등의 최적 작동시간을 추적하기 위해 보행자의 통행 분포를 알아보고자 연구지역인 경북대 캠퍼스 내에서 사계절 중 여름철 야간 보행자의 통행패턴을 현장조사하여 분석하였다. 이를 통해 시간별, 공간별 분포 특성을 파악하고 도식화하여 보행자의 통행분포 특성을 파악함으로써 보안등의 작동시간 추적이 가능하였다.

  • Objective: The aim of this study was to examine the meanings of onomatopoeia and mimetic words contextually used contextually when children play together. Methods: The participants included 40 children (ages 3-5 years) attending "M Daycare Center" in Seoul and "S Daycare Center" in Seongnam (a city in Gyeonggi-do). Twenty rounds of play observations were conducted at the centers. Once per week from May to October 2015. Results: The onomatopoeia and mimetic words observed were primarily relate to physical movements, sounds, and shapes. These types relate to Max van Manen's life-world existentials, correlating with spatiality, corporeality, and relationality. The characteristics of onomatopoeic and mimetic words used were additive and were used by the children to refine and diversify their language skills and enrich their linguistic imaginations. Conclusion: Onomatopoeic and mimetic words help children design their own play situations based on their creativity and help them share the play with their peers.

  • Architecture and music have reflected many changes occurring in a greater cultural realm. Specially, the concept of time and space formed from relativistic physics becomes the basis of cultural awareness, and a method to understand the world. Therefore, this study aims to suggest the possibility to integrate architecture and music, based on the close relationship between architecture and music of the 20th century focusing on time and space. Resultantly, in this study, interrelationship between architecture and music is elucidated by proving both the spatiality of music and the temporality of architecture, and such possibility to integrate the two realms helps understand the reality.

  • The revolution of new media has overthrown the existing social structure and brought about the changes in the concepts of the space and subject. These changes are identical to the existential issue of the space and subject and to fundamental issue of spatial design. This study will interpret the new media in view of ontology and analyze the characteristics by applying it to spatial design. In this study, the characteristics of new media of ontological viewpoint were divided into six categories containing the process space, the space of exterior meaning, the space of the affairs, interactive subject, playful subject and extension of sense, which were the basis for this analysis. The results showed that the expression characteristics of spatial concept of ontology and subject concepts revealed in the areas of architectural surface, the space of art and installation, and architectural design process.
