Over the last two decades, the attitudes to cars have changed from buying a car to sharing a car, especially among young people. Shared transport services and autonomous vehicles together can resolve the accessibility issue of shared transport services. Furthermore, they will make it possible to develop a new model of apartments without car parking. Therefore, the study estimated the demand for car sharing by young people and the running efficiency of car-sharing dealing with their car-based trip demand. The study chose nine apartment complexes for study sites where a majority of the residents were young people. The questionnaire survey was conducted to collect data on the trip demands of young people. The results showed that there are significant differences in the car-sharing use patterns and demand between the apartment houses located in the Capital region and non-capital region. Young people living in apartments in the Capital region used car sharing once per day per person for approximately 80 minutes per trip and tended to hire that between 8 AM and 10 AM. On the other hand, the young people living in apartments in the non-capital region used car sharing twice per day per person for approximately 200 minutes per trip. They tended to hire that frequently in the afternoon and evening as well as in the morning. The results also showed that a single car-sharing vehicle could deal with 3~4 trips per day in the Capital region and around 2 trips per day in the non-capital region.

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.

Cognitive radio (CR) technology based on geo-location database access approach and/or wideband spectrum sensing approach is absolutely vital in order to recognize available frequency bands in white spaces (WSs), and efficiently utilize shared spectrums. This paper presents a new structure for the TVWS database access protocol implementation based on Internet Engineering Task Force (IETF) Protocol to Access WS database (PAWS). A wideband compressive spectrum sensing (WCSS) scheme using a modulated wideband converter is also proposed for the TVWS utilization. The developed database access protocol technology which is adopted in both the TV band device (TVBD) and the TVWS database operates well in the TV frequency bands. The proposed WCSS shows a stable performance in false alarm probability irrespective of noise variance estimation error as well as provides signal detection probabilities greater than 95%. This paper also investigates Federal Communications Commision (FCC) regulatory requirements of TVWS database as well as European Telecommunications Standards Institute (ETSI) policy related to TVWS database. A standardized protocol to achieve interoperability among multiple TVBDs and TVWS databases, which is currently prepared in the IETF, is discussed.
The Beijing Convention of 2010 taken together effectively establishes a new broader and stronger civil aviation security framework. This adoption would significantly advance cooperation in prevent of the full range of unlawful acting relation to civil aviation and the prosecution and punishment of offenders. First, the Beijing Convention of 2010 will require parties to criminalize a number of new and emerging threats to the safety of civil aviation, including using aircraft as a weapon and organizing, directing and financing acts of terrorism. These new treaties reflect the international community's shared effort to prevent acts of terrorism against civil aviation and to prosecute and punish those who would commit them. Second, this convention will also require States to criminalize the transport of biological, chemical, nuclear weapons and related material. These provisions reflect the nexus between non-proliferation and terrorism and ensure that the international community will act to combat both. Third, this Convention shall not apply to aircraft used in military, customs or police services. As a substitute, International Humanitarian Law will be applied in a case. Moreover, the National Jurisdiction and the application of the law will be extended farther. The treaty promotes cooperation between States while emphasizing the human rights and fair treatment of terrorist suspects.
Since the 20th century, it was often announced that a painting was dead, but it is still alive. Even in the epoch of recently increasing virtuality, painting is still appealing, consistently pursed by many with a thirst. Thus, it is said that the mission of a picture is to maintain its reality without being trapped in virtuality. In the history of Western painting spanning over several hundreds of years the myriad of techniques and styles have emerged, going though a huge variety of changes: namely, its not possible any longer to find the new ways of expression in painting. Hence, painters today feel that it becomes more gradually difficult for them to execute something. In the midst of swiftly changing, diversely evolving trends of contemporary art, the painters incessantly pose a question why they go on working on painting, and seek to find its answer. Why the painters still try to say something about painting? Is that because they consider it the quintessence of fine arts or think that it is in no way possible or meaningful to comment on fine arts without relying on painting? If then, is there any avenue of escape for the painting? The question of the 'crisis of painting' is still raised, when reviewing the rapidly changing conditions of inventing artworks. That is also why the recent works failed to offer a conceptually unified, universally shared perspective of painting. Moreover, painting is left to shrink comparatively with the pervasive existence of videos and installations briskly employing digital images and technologies in their creations. Whats more problematic is the fact that there is a growing sense of crisis not only in the sphere of painting hut also in the entire realm of art. As the organizers and curators of big-scale exhibitions and art projects tend to exploit their space spectacularly, focusing primarily on their abilities to control the space, there is a pervasive notion amongst them that painting is a medium that is not properly to suit such purposes and requests. Today, the death of painting is, in fact, the death of modernist painting, which assumed a central role in the history of art for a considerable amount of time, rather than the death of painting itself. Employing a new paradigm of invention, a picture is now entering a new domain which is perhaps unknown to us. Moving beyond the stereotypical concepts of painting, physical property and flatness, pictures today reveal the introduction of time and space and the penetration of new media such as installation, photography, video and the Internet. Despite such trends, the dexterity and tactile capability of painters is still to be considered significant in the future. The renewal of painting is made in an entirely unexpected manner and place.

PCI Express is a bus technology that connects the processor and the peripheral I/O devices that widely used as an industry standard because it has the characteristics of high-speed, low power. In addition, PCI Express is system interconnect technology such as Ethernet and Infiniband used in high-performance computing and computer cluster. PGAS(partitioned global address space) programming model is often used to implement the one-sided RDMA(remote direct memory access) from multi-host systems, such as computer clusters. In this paper, we design and implement a OpenSHMEM API based on PCI Express maintaining the existing features of OpenSHMEM to implement RDMA based on PCI Express. We perform experiment with implemented OpenSHMEM API through a matrix multiplication example from system which PCs connected with NTB(non-transparent bridge) technology of PCI Express. The PCI Express interconnection network is currently very expensive and is not yet widely available to the general public. Nevertheless, we actually implemented and evaluated a PCI Express based interconnection network on the RDK evaluation board. In addition, we have implemented the OpenSHMEM software stack, which is of great interest recently.

Recently the customers wanted their living space to make a different from others in the field of interior design in particular, therefore, this dissertation focused on the process of the determination of the interior plan through the communication between clients and workers. This thesis indicated the interior design process with IDEF${\emptyset}$ in order to show how many kinds of information workers and expected residents made and shared in the each step of CIDP. BIM in the customized interior design procss is useful to correct drawing errors, help customers' decision-making by showing the 3D model for their own house and decrease the heavy workload of workers concerned by using BIM estimating system.
This study recognizes the importance of the social network platform as a new fashion media, and analyzes the significance of various digital fashion images, based on the 'Aura' theory of Walter Benjamin. The concept of "Disappearance of Artistic Aura" can be summarized into three discussions: 1) the change in the way of artistic perception, which is changes in value from worship to exhibition. 2) the change in the way of artistic acceptance, from personal to mass. 3) the emergence of new artistic concepts such as camera and film. By reviewing characteristics of the $21^{st}$ digital replication era, the study tried to discover and evaluate the expanded significance of the 'Aura' represented on digital fashion images, which are infinitely generated, modified, reproduced, transmitted, and shared in social network environments. The 'Burberry Instagram' was chosen as the subject of the study. The study reviewed around 2,500 images, which were uploaded from February 2011 to July 2016, and selected 200 images deemed the most representative of Burberry, and categorized and analyzed by the extended concept of 'Aura'. The study results as follows: First, the 'Aura' in digital fashion image appearing on social network platforms signifies the expansion of product value in fashion, and it also represents inherited traditions and modernization of images. Second, it also signifies the democratization and globalization of fashion through the open replication and sharing as well as the interaction of criticism and acceptance. Third, it signifies the personalized taste and fashion as everyday lifestyle, through personalized services, securing playful space, and real-time updates.

Recently, the military need more various education and training because of the increasing necessity of various operation. But the education and training of the military has the various difficulties such as the limitations of time, space and finance etc. In order to overcome the difficulties, the military use Defense Modeling and Simulation(DM&S). Although the participants in training has the empirical knowledge from education and training based on the simulation, the empirical knowledge is not shared because of particular characteristics of military such as security and the change of official. This situation obstructs the improving effectiveness of education and training. The purpose of this research is the systematizing and analysing the empirical knowledge using text mining and network analysis to assist the sharing of empirical knowledge. For analysing texts or documents as the empirical knowledge, we select the text mining and network analysis. We expect our research will improve the effectiveness of education and training based on simulation of DM&S.
The study on plane composition in clothing was focused mainly on woven wear earlier but its application has been reaching the knit wear. This study is confined to the utilization with geometrical linear pattern in the modern apparel. The work here intends to grasp the plane structure found in both woven wear and knit wear and, in particular, to understand the aesthetics of fashion. The modern flat patterned clothing has been affected by the oriental style or postmodernism in view of social and cultural aspect while its fabric material and expression method shows the diversity in terms of industrial and technical aspect. It can be characterized as several outstanding patterns: the geometrical pattern in structure, the linear pattern with seam line and 2-dimensional plane pattern without seam line, and the flexible silhouette integrated into one single shape with human body unlike the traditional apparel The aesthetics of fashion in modern flat patterned clothing can be divided into such category as the organically spatial change, the re-creation of tradition and the non-format framework. The organically spatial change shows the geometrical formation in clothes due to change in dimension, where the organically changing uniformity and generosity appears as the dimension progresses. The timeless without any difference of up and down, left and right, and inside and outside and the discontinuity due to limitless spatial change are also imbedded. The re-creation of tradition tells the reshaped spirits of old tradition by integrating and modifying the hereditary features in the old customed clothing into modern clothing. The modern flat patterned clothing implies the contemporaneousness or the frame through which the old and modern cultures may be shared and indicates the re-creation of the past and uniformity. The non-format framework contains the uncertainty in meaning and it doesn't have any certain standards. As both the apparel and the human body with this style aim at the open space, the numerous contingencies are realized.
