In context awareness using multiple sensors, when using sensor data detected and sent by each sensor, it is necessary to give different weights for each sensor. Even if the same type of sensor is configured for the same situation, sometimes it is necessary to assign different weights due to other secondary factors. It is inevitable to assign weights to events in the real world, and it can be said that a weighting method that can be used in a context awareness system using multiple sensors is necessary. In this study, we propose a weighting method for each sensor that reports to the host while the sensors continue to detect over time. In most IoT environments, the sensor continues the detection activity, and when the detected value shows a change pattern beyond a predetermined range, it is basically reported to the host. This can be called a kind of data stream environment. A weighting method was proposed for sensing data from multiple sensors in a data stream environment, and the new weighting method was to select and assign weights to data that indicates a context change in the stream.

This research paper explores the process of developing skateboarding spaces in urban parks. Skateboarding is one of the most popular sport activities representative of urban parks. This research paper will analyze the process of introducing skateboarding activities into park spaces and their acceptance by the general public as well as derive meaningful general implications for park space development planning. The research method is a discourse analysis of newspaper articles regarding skateboarding issued between the 1960s and 2010s. These articles are the main resources to show the creation of a skateboarding culture, generation of skate park spaces, and the extinction of these spaces during the research period. The result of this research is as follows. There are reasons that allowed for the creation of skate park spaces in urban parks. First of all, positive associations that people have regarding skateboarding have influenced the park's users and operators' decisions that a park is proper space for skateboarding activities, and the agreement to remodel the park space. Secondly, skate parks became a space for multiple-uses that can be shared with other emerging sports, which resulted in a building boom of skateboarding spaces in urban parks. Thirdly, urban parks and their new culture of active sports became a marketing tool used by local governments to attract new inhabitants to their new towns. On the contrary, there are three main reasons for the deterioration of skate parks. First of all, within parks in which skateboarding activities collided with other park usage, the skate parks disappeared. Secondly, skate parks built specifically for competitive skateboarding events and without consideration of casual skaters disappeared, as these facilities were not sustainable for use in the long term. Thirdly, the golden age of skate park skateboarding did not last long, as skateboarding trends shifted from trick performance to street skating, where skate parks are no longer needed. For this reasons, the exclusive use of park space for skateboarding activities has faded from public interest. The findings of this research suggest how sport activities should be introduced to urban parks. At first, each park's management needs to identify a sport suitable for long-term development, and not only plan for temporal events or follow fleeting trends. Secondly, the park's management systems should reflect a type of sport activity that would not only be popular at the beginning of the spaces development, but also take into consideration how these activities will change over time. Lastly, in cases where there are conflicts between sport activities and other activities in urban parks, attempts should be made to suggest feasible solutions other than the liquidation of sport spaces. This study explains the development process of sport spaces offered in urban parks, by thorough research of the process of acceptance of skateboarding activities in current urban park systems. This conclusion also indicates further areas for research with the purpose of understanding general best practices in urban parks sport space planning.

The purpose of this study is to develop a new architectural language and design strategies that would anticipate and incorporate new historical situations and new paradigms to understand the world. It consists of four sections as follows: First, it presents a new interpretation of space, human body, and movement that we find in modern art and tries to combine that new artistic insight with environmental design to provide a theoretical basis for performance-event architecture. Second, it conceives of architectural environment as a combination of space, movement, and probabilistic situations rather than a mere conglomeration of material. It also perceives the environment as a stage for performance and the act of designing as a performance. Third, in this context, man is conceived of as an organic system that responds to, interacts with, and adapts himself to his environment through self-regulation. By the same token, architecture should be a dynamic system that undergoes a constant transformation in its attempt to accommodate human actions and behaviors as he copes with the contemporary philosophy characterized by the principle of uncertainty, fast-changing society, and the new developments in technology. Fourth, the relativistic and organic view-point that constitutes the background for all this is radically different from the causalistic and mechanistic view that characterized the forms and functions of modernistic design. The present study places a great emphases on dematerialistic conception of environment and puts forth a disprogramming method that would accommodate interchangeability in the passage of time and the intertextuality of form and function. In the event, performance-event architecture is a strategy based on the systems world-view that would enable the recovery of man's autonomy and the reconception of his environment as an object of art.

Korean universities has promoted the entrepreneurship education. University entrepreneurship education has three methods(entrepreneurship lecture, startup events, and institutional supports). This study examined that university entrepreneurship education has how to affect students entrepreneurial intentions. For the empirical investigation of the hypotheses of this study, surveys have been carried out 100 university students who are studying entrepreneurship education in Gangneung area during september 2016. The results of the empirical analysis are as follows : First, venturing space has a significant impact to entrepreneurial intention. Second, entrepreneurship lecture, start-up events, and mentoring does not affect entrepreneurial intention. As a result of this study, university students in Gangneung proved that entrepreneurship lecture, start-up events and mentoring did not affect the entrepreneurship intention. On the contrary, venturing space has a significant impact to entrepreneurship intention. This results suggest that improve entrepreneurial intention of university students needs practical assistance for start-up. This study has limitations have the generalization. The results are limited to Gangneung area, if this study has increase sample surveys or magnify area, it is possible to have produce different results.

This study suggests a novel way of safety cognition with single sensor. It is beneficial to make the most of the 3-axis acceleration sensor for context inference. It has remarkable advantages that size is too small and less malfunction or error. This study shows the calculation of the common life safety through the events data from the 3-axis acceleration sensor only. That includes the analyzation of the volume of energy and converting quantitative numerical value.

현재 기업에서는 DW 및 BI 가 업무를 분석하는 수단으로 널리 사용되고 있다. 그러나 적절한 시점에서 기업의 의사결정을 위한 정보 수집 및 리포트 생성 사이에 통상 시간 차이가 발생한다. 이러한 데이터 지연의 원인으로는 업무 프로세스 및 시스템 통합화의 문제점 등을 들 수 있다. 본 논문에서는 데이터 지연의 문제를 처리할 수 있도록 실시간 비즈니스 모니터링을 위한 5 레이어 아키텍처와 이를 모델링하는 절차를 제안한다. 제시된 아키텍처는 비즈니스 이벤트 발생 과정을 모델링하는 요소를 통합하고, 수집된 비즈니스 속성에 대하여 실시간으로 액세스할 수 있게 한다.

네트워크의 발전과 함께 인터넷을 통한 기업 활동이 점차로 증가하면서 기업들간(B2B)에 실시간 데이터를 안전하게 서비스하기 위하여 여러 개의 시스템이 거미줄처럼 연계되고 있다. 전통적으로 기업들간에는 EOI(Electronic Data Interchange) 시스템과 독자적인 부가가치 통신(VAN, Value-Added Network)을 통한 데이터 교환방식을 사용했으나, 이 모델은 초기비용이 비쌀 뿐만 아니라, 데이터를 실시간 이벤트가 아닌 일괄작업(batch)으로 처리하였다. 그러나, 현재 B2B 간의 데이터 교환 및 상호 작용 방법으로 인터넷, XML, 그리고 메시징 시스템을 사용하고 있으며 특히, 메시징 시스템은 소규모의 시스템이 B2B에 참여하거나 탈퇴하는 비즈니스 작업의 어려움을 덜어준다. 본 논문에서는 인터넷상에서 이루어지는 B2B간의 데이터 교환 및 상호 작용을 위하여 메시징 시스템중 대표적인 JMS를 기반으로 안전한 데이터 교환 모델을 설계 및 구현한다. 따라서, 본 논문에서 제시하는 메시징 모델을 B2B 시스템에 적용하면 기업들간 안전한 메시지 전송을 보장할 수 있다.
