  • We used actual field data to analyze from a traffic engineering perspective how AI and edge computing technologies affect the reduction of traffic accidents. By providing object information from 20m behind with AI object recognition, the driver secures a response time of about 3.6 seconds, and with edge technology, information is displayed in 0.5 to 0.8 seconds, giving the driver time to respond to intersection situations. In addition, it was analyzed that stopping before entering the intersection is possible when speed is controlled at 11-12km at the 10m point of the intersection approach and 20km/h at the 20m point. As a result, it was shown that traffic accidents can be reduced when the high object recognition rate of AI technology, provision of real-time information by edge technology, and the appropriate speed management at intersection approaches are executed simultaneously.

  • This study aimed to assess the spatial cognition strategies and roles taken by students in the process of solving spatial tasks. For the analysis, this study developed two spatial tests based on the mental rotation test, which were taken by 63 students in their final year in elementary schools. The results of this study showed that in terms of the method of approaching the tasks, students took the comprehensive approach and the partial approach. When solving the tasks, the students were shown to use the imagery thinking or analytic thinking method. In terms of perspective, the students rotated the object or change their perspectives. A comparison of the methods used by the students revealed that when approaching the tasks, the group of students who chose the partial approach had higher scores. In terms of solving the tasks the analytic thinking method, and in terms of perspective, changing perspectives were shown to be more effective. Such effective methods were used more frequently in discrimination tasks than in recognition tasks, and in more complicated items, than in less complicated items. In conclusion, the results of this study suggested that the partial, analytic approach and the change of perspectives are useful strategies in solving tasks which require high cognitive effort.

  • This study is to make a framework of newly interpretating the dynamic change of regional or local landscape rapidly occurred after the establishment of the nation state and capitalistic system. The basic concepts of making an interpretative framework are power, subjectivity, and performativity. The framework of closely interrelating the three concepts developed in the near future will be applied to the interpretation of variety of (de)centralized landscapes in regions or locals. A centralized political power under the nation state has destroyed or marginalized the historically developed landscapes, traditional culture, and subjects' values in regions or locals by the political implementation of the nation state, the establishment of national identity, a centralized economic development, and so on. The landscapes produced by the political power of the nation state can take a role as a cause of conflicts in regions or locals in terms of a historical perspective. Landscapes are being made by various subjects, and the produced landscapes also positively or negatively will influence the emotion, cognition, and behavior of the subjects particularly in a performative perspective. The dynamics interrelation between subjects and landscapes has been disguised or marginalized by reason/rationality, totality/collectivity, the separation between reason and emotion mainly made by modernism, the nation state, a capitalistic system. The interrelation between landscapes and subjects is especially emphasized on people's resistibility and creativity. Lastly, landscape is not a concept given as a priori or (re)presented objectively. It is not also a material or an object independently existed from a subject's emotion and cognition. It should be interpreted through a performative relation with subjects. Performativity will take an active role of combining the materiality of landscape, power, and subjectivity. It is also important to understand the active role of landscapes.

  • The change of the development of transport and logistics systems occurs with the active change of technology and the advent of the era of Industry 4.0. It requires modernization of approaches to the development of transport and logistics systems at the macro and micro levels. The present study aims to identify perspective directions of development and evolution, find out the existing obstacles in the integration of technological solutions of transport and logistics systems at the macro and micro levels. This study is based on a quantitative and qualitative methodology for assessing the level of integration of technologies into transport and logistics systems to study the prospects for their development at the micro level. Macroeconomic indicators of transport and logistics in the context of different regions of the world were used to quantify the development prospects. For a qualitative assessment of the development of the transport and logistics system, the case study method was used. The object of the study was selected logistics company Sensco Logistics Inc., Austin TX. At the macro level, countries with more innovative logistics sectors have stronger mechanisms for coordinating private sector activities. Simplification of administrative procedures of control and regulation by the public sector in order to facilitate trade between countries is a promising direction for the development of transport and logistics systems. Such reforms are more effective in developing a "rigid" transport infrastructure. The integration of Industry 4.0 technology solutions into the international logistics sector is defined by political and legal barriers, especially in developing countries. In low-income countries, hard and soft infrastructure reforms are hindering the development of logistics companies that provide transport services. This determines the national level of development of transport and logistics systems, and in general the global level of development of transport and logistics. In developed countries, the legal barriers to the development of new technological logistics are environmental requirements for the integration of technologies into the transport system. These trends are slowing down the development of International Logistics, which, compared to other industries, is slower to integrate Industry 4.0 technologies. This study combines macroeconomic factors that determine the prospects for the development of transport and logistics systems at the micro level.

  • This article apprehends Yeongdae (靈臺), the most sacred shrine of Daesoon Jinrihoe which has earlier historical precedents, as an example of material religion. In East Asia, the first Yeongdae was a structure that King Wen of Zhou commissioned to be built. As the time passed by, the meaning of Yeongdae was changed to signify a mental yeongdae, the object and the aim of cultivation, and the notional mindset that appears in the Daoist meditation, Cunsi (存思, visualization). This implies that Yeongdae has signified both material and non-material objects. Throughout most of history, these two concepts had never been related to each other, but shifted in form and meaning depending on context. Daesoon Jinrihoe, which emerged in the modern era of Korea, used the concept of investiture of gods and combined the two into one. Accordingly, the Yeongdae, referred to by King Wen to indicate his shrine, was expressed as a spot wherein the gods were enshrined on the earth. As an innovation, Daesoon Jinrihoe argued that gods correspond to properly eligible human beings according to the degree of their cultivation and that sacred space was instead defined a spot within the human mind, a mental yeongdae, where the gods could be enshrined into humanity (神封於人). From the perspective of Lévi-Strauss, the factors that are discovered in the tradition of East Asia, namely, the Yeongdae of King Wen and the mental yeongdae of Zhuangzi can combined with consistency and established in the doctrinal system of Daesoon Jinrihoe. Such an attempt refers to bricolage which re-creates the traditional concepts of the past. In this regard, the concept of invented tradition coined by Eric Hobsbawm could also be used to conclude that the Yeongdae (the shrine of gods) of Daesoon Jinrihoe can be expressed as an invented Yeongdae, which transcends the existing categories of material yeongdae and non-material yeongdae.

  • The purpose of this paper is to illuminate the implication of feminist oral history from a postcolonial feminist perspective as critically reexamining the relationship between hearer and speaker, representer and narrator, the said and the unsaid, and secrecy and silence. Based upon oral (life) history of a U.S. military prostitute (yanggongju), I tried to show the experiences of a historically-excluded and marginalized 'Other,' and then critically reevaluate the meaning of encountering 'Other', not just through the research process but also in the post/colonial society in Korea. The narrative of an old woman in the "kijichon" (a formal prostitute in U.S. military base) shows how woman has navigated the boundaries between inevitability/coincidence, the enforced/the voluntary, prostitution/intimacy, and military prostitute/military bride while continually negotiating as well as having conflict with various myths and ideologies of the 'normative woman,' 'nationhood,' and 'normal family.' In addition, her narrative which causes the rupture of our own stereotypical images of a military prostitute not only proves the possibility of reconstructing the self-identity of a subaltern woman, but also redirects the research focus from the research object to the research subject (ourselves). Consequently, the implication in feminist oral history is that feminist researchers who whish to represent the experiences of other should first inquire 'what/how we can hear,' 'why we want to know others,' and 'who we are,' while simultaneously asking if subaltern woman can speak.

  • Sensor modeling of high-resolution satellites is a prerequisite procedure for mapping and GIS applications. Sensor models, describing the geometric relationship between scene and object, are divided into two main categories, which are rigorous and approximate sensor models. A rigorous model is based on the actual geometry of the image formation process, involving internal and external characteristics of the implemented sensor. However, approximate models require neither a comprehensive understanding of imaging geometry nor the internal and external characteristics of the imaging sensor, which has gathered a great interest within photogrammetric communities. This paper described a comparison between rigorous and various approximate sensor models that have been used to determine three-dimensional positions, and proposed the appropriate sensor model in terms of the satellite imagery usage. Through the case study of using IKONOS satellite scenes, rigorous and approximate sensor models have been compared and evaluated for the positional accuracy in terms of acquirable number of ground controls. Bias compensated RFM(Rational Function Model) turned out to be the best among compared approximate sensor models, both modified parallel projection and parallel-perspective model were able to be modelled with a small number of controls. Also affine transformation, one of the approximate sensor models, can be used to determine the planimetric position of high-resolution satellites and perform image registration between scenes.

  • This study originated from following questions. What can we understand the conception of deconstruction, which has been the core idea of new discourses developed in various ways since modernism? How can this question be interpreted in landscape design? What is the conceptional frame of integration the prominent hybrid post-genre movements and phenomena? The frame can be epitomized with the deconstruction phenomenon. 'Deconstruction' is the core conception appeared in late or post-modern ages in the embodiment of modernity and can be viewed as an integrating or a hybrid phenomenon between areas or genres in formative arts. Therefore, the author regards the hybrid movements widely witnessed in the post contemporary formative arts as one of the most important indicators of de-constructive signs. It is safe to say that the phenomenon of this integration or hybridism, of course, does not threaten the identity of landscape design but serves as an opportunity to extend the areas of landscape design. One of the consequences of this integration or hybridism is the voluntary participation of users who have been alienated in the production of the meanings of design works and hybrid landscape design with the hybridization of genres that is characterized with transformation in forms. This view is based on the distinction between hybridization of interactions between the designer (the subject) and the user (the object), and hybridization of synesthesia. Generally speaking, this is an act of destroying boundaries of the daily life and arts. At the same time, it corresponds to vanishing of modern aesthetics and emerging of post-contemporary aesthetics which is a new aesthetic category like sublimeness. This types of landscape design tries to restore humans' sensibility and perceptions restrained by rationality and recognition in previous approach and to express non-materialistic characteristics with precaution against excessive materialism in the modern era. In light of these backgrounds, the study aims to suggest the hybrid concept and to explorer a new landscape design approach with this concept, in order to change the design structure from 'completed' or 'closed' toward 'opened' and to understand the characteristics of interactions between users and designs. This new approach is expected to create an open-space integrating complexity and dynamics of users. At the same time, it emphasizes senses of user' body with synesthesia and non-determination. The focus is placed on user participation and sublimity rather than on aesthetic beauty, which kind of experience is called simulacre. By attaching importance to user participation, the work got free from the material characteristics, and acceptance from the old practice of simple perception and contemplation. The boundaries between the subject and object and the beautiful and ordinary, from the perspective of this approach, are vanished. Now everything ordinary can become an artistic work. Western dichotomy and discrimination is not effective any more. And there is 'de-construction' where there is perfect equality between ordinary daily life and beautiful arts. Thus today's landscape design pays attention to the user and uses newly perceived sensitivity by pursing obscure and unfamiliar things rather than aesthetic beauty. Space is accordingly defined to take place accidentally as happening and event, not as volume of shape. It's the true way to express spatiality of landscape design. That's an attempt to reject conventional concepts about forms and space, which served as the basis for landscape design, and to search for new things.

A Comparison between the Religious Ethics of Christianity and Daesoon Jinrihoe: 'Love Your Enemies' versus 'Grievance-Resolution for Mutual Beneficence' (기독교와 대순진리회의 종교윤리 비교연구 - 원수사랑과 해원상생을 중심으로 -)

  • The two religious ethics, Christianity's 'love your enemies' and Daesoon Jinrihoe's 'grievance-resolution for mutual beneficence', can be misunderstood as similar. The misunderstanding arises from these religious ethics having something in common that specifically points to a particular object, called an enemy, and contains instructions to treat that object altruistically. However, from the perspective of Religious Ethics, the two teachings are not the same. The beliefs they are based upon are different, the religious character they pursue is different, and their processes of obtaining legitimacy, logic, and implementation are different. The most distinct difference between these ethics is that the Christian ethic focuses on a victim's role whereas Daesoon Jinrihoe ethic emphasizes the roles of both victims and perpetrators. In case of 'love your enemies,' if a perpetrator turns away from a victim and believes that they would be forgiven for their sin, the victim is unlikely to practice the teaching 'love your enemies.' Accordingly, to avoid criticism over cases wherein love of an enemy is nothing but a shallow grace, the roles of the two sides should be more highlighted than that of the absolute being. As for grievance-resolution for mutual beneficence, this teaching encourages victims to resolve their grievance with a goal of mutual beneficence. The perpetrator should likewise resolve the grievances and grudges of their victim with the aim of mutual beneficence. Jeungsan especially stressed that perpetrators have to resolve 'Cheok (慼: the resentment and grievances that someone holds against the one who victimized them)' through the ethic of grievance-resolution in order for living well. In other words, 'the ethic of Cheok-resolution' is an ethic wherein the perpetrator also plays an important role in the implementation of grievance-resolution for mutual beneficence.

  • Technological change leads to a value shift in human society. Various cultural experiences through the digital paradigm influence the expression of fashion. This article considers fashion film as a new form for presenting fashion and explores the distinctiveness of expression in digital fashion film. For the methodology, a literature review was conducted to examine the concepts and features of digital fashion film and metareality. Empirical research was also performed by drawing from Nick Knight's digital films, "Sans Couture", "#asif", and "The Elegant Universe" and by specifically analyzing the classification of the themes, visuals, and auditory expression. The results are as follows. The proliferation of fashion film has accelerated in the internet environment. New media in the digital era allows images to become more realistic and variable through immaterial conversion. Metareality is the notion of a reality beyond existence. A metarealistic image maintains the metaphysical nature of an object and transcends empirical appearance. It possesses immaterial, transboundary, and multidimensional features, and the image is realized by digital technology. The expression analysis identifies the metareality expressed in contemporary fashion film appearing as atypical forms, irrational combinations, and the playfulness of motion. It shows a positive attitude, transcending the immaterial limit of reality toward fashion. This study indicates how fashion as products challenges the metaphysical transformation in the digital era. The exploration of metareality in digital fashion film promotes a wider perspective and understanding of the concept of fashion.
