The ontological status of Newtonian space-time has been debated under the name of substantivalism-relationism controversy. The debates between the two parties are concerned with the nature of existence of space-time. Substantivalism maintains that the points of space-time have existence analogous to material substance. Relationism claims that space-time should be understood as the framework of possible spatio-temporal relations between bodies. Newtonian space is considered as a three dimensional entity in accordance with our geometric common sense. Yet given that the concept of motion is defined as the change of position throughout time, it is possible to interpret space-time as a 4 dimensional entity. In this essay, substantivalist-relationist debate is considered within the context of non-relativistic 4 dimensional space-time theory. This essay attempts to clarify the dispute over the ontology of space-time by elucidating the relationship between the ontology of space-time, motion, and space-time symmetry.

본 논문은 반 프라쎈의 뉴턴 시공간에 대한 해석에 기초한 경험동등성 논변을 비판한다. 필자의 주장은 반 프라쎈이 시공간에 대한 오해에서 절대속도라는 뉴턴 시공간이 가지는 여분의 구조를 통해 부적절한 비판을 낳고 있다는 것이다. 반 프라쎈의 경험동등성 논변은 모형의 다양한 측면을 무시한 뉴턴 시공간에 대한 부주의한 해석에 근거한다.

본 논문은 라이프니츠와 클라크 간의 공간의 본질에 대한 논쟁과 이를 바탕으로 한 최근 형이상학과 과학철학의 논쟁을 고찰한다. 공간의 본질에 대한 논의는 존재론적 위상에 대한 논쟁으로, 실체론(substantivalism)과 관계론(relationism)의 두 축을 중심으로 진행된다. 클라크에 의해 대변되는 실체론자들은 공간이 물체와 같이 그 자체적으로 존재하는 실체(substance)임을 주장한다. 반면, 라이프니츠를 위시한 관계론자들은 공간의 독립적인 실체성을 부정하고 공간이 물질들 사이의 관계(relation)로 환원될 수 있다고 주장한다. 라이프니츠는 식별불가능자 간의 동일성 원리와 충족이유율을 이용하여 실체론의 주장을 비판하는 논변을 제시한다. 이어만과 노턴에 의해 제시된 홀 논변은 고전적인 라이프니츠의 논변을 현대적인 문맥에서 계승하여 재구성한다. 본 논문은 이들 논변의 형이상학적 측면을 고려한다. 이를 통해 공간의 존재론에 대한 논의가 형이상학적 논쟁에 머무르지 않고 운동을 이해하는 역학 이론의 개념적 기초를 이루고 있음을 부각한다.

In the display of virtual space, the degree of space virtualization cannot be judged only by the degree of material technology. Based on the non-material relationship, the virtual space that this research focuses on is a conceptual and ontological point of view (based on the conceptual and ontological viewpoints of non-material relations), including practical technical issues. The research on the characteristics of virtual space ontology not only has an impact on the space design of science fiction movies, but also becomes a powerful medium that brings changes to the world. In the future, there will be a large number of cases where fantasy things in science fiction movies are actualized. From this perspective, based on the study of several science fiction movies using virtual reality scenes, this paper puts forward a study on the representation characteristics of virtual space ontology. In addition, the study of the virtual reality is of great significance for verifying the possibility of virtual reality in the application of deep space technology in the future. At the same time, it provides reference value for the development of special effects film field from montage theory-based to Bazin theory-based expression, and contributes to the theoretical system of film space.

The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping malls where there are crowds of people. At this time, government has spent a lot of money in installing various types of safety facilities for preparations of increasing potential disasters. Therefore, an effective facility management system is required. In this paper, we propose an information retrieval process to effectively extract the facilities' information based on the ontology and spatial analysis in underground space. The ontology-based searching supports hierarchical and associated results as well as knowledge sharing with hierarchy concepts. The spatial analysis based searching has "Buffer" and "Near" functions to operate on a map without understanding any property of the facility information.

In spite of various attempts to characterize the ontological status of space-time, Newtonian substantivalism and Leibnizian relationism, what is really at issue in the controversy between the two parties is by no means clear. This essay argues that from the perspective of space-time symmetries, classical space-time can be unambiguously classified as substantival space-time and relational space-time. The symmetries of space-time theories distinguish the invariant geometric relationships between events. The essential difference between the two space-times stems from whether or not there exists the affine structure that distinguishes the inertial trajectories of a given body.

본 논문은 시공간 이론의 역사적 발전 사례를 통한 비관적 귀납논증을 비판적으로 고찰한다. 시공간이란 이론적 존재자는 역학이론 발전과정에서 급격한 존재론적 변화를 경험했다는 점에서 비관적 귀납 논증에 대한 증거로서 제시된다. 필자는 이러한 주장이 시공간이 운동현상을 인과적으로 설명한다는 시공간이론에 대한 잘못된 해석에서 기인한다고 주장한다. 이러한 해석은 고전역학과 상대론 구조들 사이의 차이점만을 부각하기 때문이다.

The u-Healthcare system, a new paradigm, provides healthcare and medical service anytime, anywhere in daily life using wired and wireless networks. It only doesn't reach u-Hospital at home, to manage efficient personal health in fitness space, it is essential to feedback process through measuring and analyzing a personal vital signs. MBAN(Medical Body Area Network) is a core of this technology. MBAN, a new paradigm of the u-Healthcare system, can provide healthcare and medical service anytime, anywhere on real time in daily life using u-sensor networks. In this paper, an ontology-based context-awareness in MBAN proposed system development methodology. Accordingly, ontology-based context awareness system on MBAN to Elderly/severe patients/aged/, with measured respiratory rate/temperature/pulse and vital signs having small variables through u-sensor network in real-time, discovered abnormal signs and emergency situations which may happen to people at sleep or activity, alarmed and connected with members of a family or medical emergency alarm(Emergency Call) and 119 system to avoid sudden accidents for early detection. Therefore, We have proposed that accuracy of biological signal sensing and the confidence of ontology should be inspected.

The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.
