The purpose of the research was to examine the effect of field of view on egocentric distance perception in the real and virtual environment. The replica that mimicked the real environment condition was used to create the virtual environment condition. We manipulated field of view levels equally in both viewing conditions using glasses that limit the field of view in real-world conditions and limiting the field of view in virtual-world conditions in a manner equivalent to real-world conditions via HMD. Eighteen participants observed the target with a limited field of view in a real and virtual environment without head movement. Then, we measured perceived distance using the timed imagined walking method, which measures the time taken by each participant to mentally walk to the target. The target was shown three times at three different distances from the participants: 3, 4, and 5 m. For the analysis, we converted time estimates into distance estimates. Consequently, the estimated distance in the virtual environment condition was less than the estimated distance in the real environment condition. And as the field of view shrank, the estimated distance also decreased. The estimated distance did not vary with field of view levels in real-world conditions. In the virtual environment, the estimated distance decreased as the field of view decreased, whereas in the real environment, the estimated distance increased. The implications of the results and some future research directions are discussed below.

Koreans' traditional view on death has been much influenced by Confucianism, Taoism, Buddhism, and shamanism since ancient times. Confucianism emphasizes the importance of the real life in this world and highly praises doing good deeds for the family and the community. It also praises people who are enlightened by education and self-discipline. Confucian scholars admit that death cannot be understood by rational thinking although it is unavoidable as a cosmic order. Taoism sees life as the same entity as death; Both are two different aspects of the same cosmos or the wholeness. However, the disciples of Taoism became much interested in a long life and well being that may be achieved by harmonizing with the cosmic order. Buddhism thinks that death and life are an "illusion". It says that people can be enlightened by recognizing the fact that "Nothing is born and nothing is dying in this world. Everything is the product of your mind occupied with false belief." However, secular Buddhists believe in the afterlife and metempsychosis of the soul. This belief is sometimes connected with the view of the traditional shamanism. Shamanism dichotomizes the world between "this world" and "that world". After death, the person's soul travels to "that world", where it may influence life of people who reside in "this world". And shamans who are spiritual beings living in "this world" mediate souls and living people. In conclusion, there are various views and beliefs regarding death, which are influenced by a number of religions and philosophies. They should be seriously considered when making a medical decision regarding the end of patients' life.

Radical paradigm shift is being expected due to the coming of the so-called intelligent society. In the intelligent society, things or machines are able to use intelligence for the first time in history and this will bring about fundamental changes at every corner of human society. This article analyzes views of the world in order to figure out basic directions of this paradigm shift. A dualistic view of world mediated by technology is suggested for a new world view of the intelligent society, based on comparison of a traditional dualistic view of world between human-nature and a tripartite view of world between human-machine-nature. This article summarizes paradigms of the intelligent society into four ; externalization of intelligence, productivity explosion, platform society, and self-organizing society. These new paradigms will provide lots of benefits such as intelligence augmentation, production capacity increase, and self-organizing effect. But at the same time, it will increase risks of system failure because of loss of human control on technologies. In conclusion, it is argued that human choices and efforts will decide the future of the intelligent society becuase the paradigm shift is value neutral in essence.

Master Jeungsan understood a general view of Pungsu but actually he used the theory of Pungsu in his own religious perspective, transcending it. The theory of Pungsu is different. But the fact that it is premised on the principle of 'in and yang', the five-element principle, the Book of Changes, energy thought, and To chugi piyung, etc. is generally recognized. The three important elements of Pungsu are mountain, water, and direction or man. Pungsu has formal principles such as Gallyongbeop, Jangpungbeop, Deuksubeop, Jeonghyeolbeop, Jwahyangbeop, and Hyeongukron. etc. In the late of Joseon, Jeungsan established a new traditional thought, understanding Bibopungsu, Gukdopungsu, Minganpungsu, etc. However, he reinterpreted them to be suitable to his religious ideal and let his followers understand them as well. In particular, Jeungsan overcame the previous view on earth and expressed a new perspective to enhance earth up to the level of heaven. In the perspective of the traditional world, earth is lower than heaven, but Jeungsan made it a status equal to heaven. He mentioned that in the past, the culture and history of man was influenced by earth's energy but today, at the age of man respect, he put passive man influenced by earth-condition on the more subjective and active status. Even though he mentioned different Pungsu, Hyeongguk, and Hyeolmyeong, he expressed the shape of Pungsu within the construction of three worlds, the one of heaven and earth transcending good or ill luck or a favorable change in fortune. He practised the expedient of Pungsu from the stand of the construction of heaven and earth instead of the usage of Bibopungsu, Gukdopungsu, and Minganpungsu. He diagnosed that the division of the world is caused by the one of earth and tried to solve it. Moreover, he said that Myeongdang(a propitious site) must be the man-orientation rather than the earth-orientation. It means that Pungsu, stressing the energy of earth and turning one's luck, is changing into the world of man-orientation. In other words, Jeungsan diagnosed the world of Pungsu but he ultimately used Pungsu theory in building up his own view of religious world transcending such a theory.

This paper describes a self-localization method for the mobile robot using panoramic view images. A panoramic view image has the information of location of the objects from the viewer robot and direction between the objects at a position. Among the sequence of panoramic view images, the target objects in the image like traffic signs, facade of a building, road signs, etc. locate in the real world so that robot´s position and direction deliver to localize from his view. With the previously captured panoramic images, the method calculates the distance and direction of the region of interest, corresponds the regions between the sequences, and identifies the location in the world. To obtain the region, vertical edge line segments

21st century has different characters from 20th century which was an era of machine and rationality based on the industrial revolution. With the advent of the digital revolution, it became an era of pluralism, culture, and emotion. The digital technology made it possible to connect the whole world together in real time and brought about the entirely new notion of time and space. It also dramatically altered the world view. Now we have a different set of social and cultural values from the past. This paper researched the influences of these social and cultural changes on public designs. The leading trends of public designs were analyzed and the successful cases were studied. The main research methodologies were the document review and the instrumental case study. The major social & cultural paradigms of a present era were classified as 'pluralism', 'digital & information revolution', 'human-centered value (against machine-centered value of 20th century)', and 'organic world view'. Each of the classified paradigms was analyzed more to find out the influences on the various trends of public designs. 'Pluralism' has influence on 'experiential public design', 'community art', and 'public design of local values'. 'Digital & information revolution' has influence on 'content-centered public design', 'smart public design', 'immaterial public design', and 'performance in public design'. 'Human-centered value' has influence on 'universal design approach in public design', and 'emotional public design'. 'Organic world view' has influence on 'sustainable public design', and 'ecological public design'.

This study is focused on viewing the March 1st Movement, a national movement uprisen nationwide during the Japanese occupation period, and women's independence movement from an angle of worldpeace. The March 1st Movement was held nationwide when our national sovereignty was lost, and it can be defined as a form of peace movement in view of world history. Particularly, the March 1st Movement was the people's independence movement without distinction of class, region and sex. The direction of national independence and freedom implied in the independence movement during that time period needs to be interpreted newly in view of world peace. Firstly, the urgent task to complete during that period was to accomplish independence in view of the times and the national people, and it was a form of peace movement. Secondly, the women who participated in the March 1st Movement changed into spontaneous participants or activists for the national independence movement and, thereafter, continued a history of women's independence movement of Korea. Lastly, the March 1st Movement became widespread domestically and to foreign countries such as China, Japan, Russia, Europe and America, so that its spirit of freedom and peace appealed to the weak countries in Asia. Furthermore, it worked as a spiritual support for the independence movement of Korea. As mentioned above, the March 1st Movement needs to be newly understood in view of world peace, and, out of that movement, Korean women's independence movement deserves a highlight as a peace movement stream in the world history of women.

Thermodynamic principles are described with a new point of view. In present study, the interaction between two systems is focused instead of the behavior of a system in conventional thermodynamics. The state change of a system cannot occur by itself but it is the result of the interaction between systems. However, the interaction itself is also the result of another kind of interaction, the interaction between two interactions. To reconstruct thermodynamics with such a point of view, the reversible world is imagined, in which conservations and measurements are discussed. There exists a conserved quantity for each mode of reversible interaction. The conserved transferring quantity in the interaction between interactions is the effective work, which is supposed to be measurable and conserved in reversible world. Effective work is the primary concepts of energy. It is the key factor to explain measurements, energy conservation and energy dissipation. The concepts developed in reversible world are applied to the real world in which irreversible phenomena may occur. Irreversibility is the result of effective energy dissipation, in which effective work irreversibly changes into entropy. A quantitative relation between the disappearing effective work and the generated entropy is dissipation equation which is given by experiments. A special temperature scale to give a very simple type of the dissipation equation is the absolute temperature scale, which gives the conventional conservation of energy.

An information sharing system, namely World Design View, is developed for browsing product design data on the World Wide Web environment. For the last few years information sharing has been rapidly emerging as an important research issue in the areas of concurrent engineering, product data management, virtual manufacturing, and so on. Since we are mainly concerned with product development, the key information that needs be communicated and shared is product data. The developed system puts the major advantages of STEP, OODB, and VRML together. The STEP standard provides a consistent data exchange format and application interfaces among different CAD/CAM systems. OODB is efficient and effective in dealing with complex data structures often found in engineering applications. Virtual worlds for 3-D product models can be created by VRML which is networked via the global Internet and hyperlinked with WWW. The World Design View system can support for members of virtual design teams, possibly distributed all over the world, to share 3-D shape information quickly and easily.
