  • In realizing ubiquitous computing, techniques of efficiently using the limited resource at client such as mobile devices are required. With a mobile device with limited amount of memory, the techniques of XML stream query processing should be employed to process queries over a large volume of XML data. Recently, several techniques were proposed which fragment XML documents into XML fragments and stream them for query processing at client. During query processing, there could be great difference in resource usage (query processing time and memory usage) depending on how the source XML documents are fragmented. As such, an efficient fragmentation technique is needed. In this paper, we propose an XML fragmentation technique whereby resource efficiency in query processing at client could be enhanced. For this, we first present a cost model of query processing over XML fragment stream. Then, we propose an algorithm for resource-efficient XML fragmentation. Through implementation and experiments, we showed that our fragmentation technique outperformed previous techniques both in processing time and memory usage. The contribution of this paper is to have made the techniques of query processing over XML fragment stream more feasible for practical use.

  • This study purpose is to discuss critically the conception of history in Hegel and Marx by drawing on Merleau-Ponty's existential theory of history, finishing with concluding remarks. Merleau-Ponty insists that history is always history experienced. This thesis is his own principle in investigating human history. From this perspective, he begins to flesh out problems with history which Hegel and Marx had understood idealistically and materialistically respectively. He criticised that if Hegel grasps history in terms of teleology, he failed to explain the source and origin of historical meaning from which history makes sense. He failed to think that what gives history meaning comes from embodied consciousness. This means that history is not made of dialectical thinking. The thing is different from such an imaginative construal. History as it stands is not like that. It is not running around like Hegelian dialectical thinking. Marx understood historical behavior wrongly when he explained class struggle in terms of productive relations. He disregarded how class was sedimented or embodied in the minds of proletarians. Owing to this, Marx could not suppose that class consciousness is determined not causally or externally but by incarnated experience. It is affected in so far as it is affected by somebody, that is, the worker. At that moment only Class consciousness begins to work. Marx did not catch sight of this hidden fact.

  • The movie, Battle of Wits which is based on the cartoon by Morihideki(森秀樹) is directed by Zhang Zhiliang(張之亮), a director from Hong Kong. Morihideki's cartoon is based on the novel by Sakemikenichi(酒見賢一). The movie represents a successful one-source multi-use case. Battle of wits, which deals with the Mozi's propaganda against war, presents the thought of Mozi School(墨家) in spring, autumn, and warring states. The movie criticizes aggressive war by powerful nations. Aggressive war is an extreme form of brutality and worthless action without any benefit. Aggressive war represents 'never each love(buxiangai, 不相愛)' and 'never each benefit(buxiangli, 不相利)' as understood by Mozi. The main character of the movie endeavors and successfully defends the enemy's attack as Mozi did. It is due to the propaganda of Mozi School 'not to attack(feigong, 非攻)' that they can defend themselves from the attack from a powerful nation. It means that 'the universal love(jianai, 兼愛)', the ideology of Mozi, is concretely actualized. The philosophy of Mozi School in the Battle of Wits has its limits as follows: the thought of Mozi School is just suitable during times of war and unnecessary in times of peace, the contradiction between universal love and hatred for one person; the Mozi School's faith in the nature of human beings to confront betrayal. This limit was also proposed in the movie. However, the movie presented how the masculinity of Mozi School, supplemented by the feminity of Daojia(道家), can succeed in achieving genuine communication. When focusing on this point, the movie can be interpreted as biased towards the philosophy of Daojia.

  • Whitehead's metaphysics and philosophy of nature rest on his awareness of the metaphysical problem of the relation between "I", the "creative advance" and forces of the universe. Whitehead attempted to systematize human experience of the world based on logical explorations. In this context it is important to note that his discussion of proposition and language is closely connected with his works on a systematic theory of nature. Whitehead proposes a metaphysical concept of proposition also based on the creative advance of the universe. His theory of proposition is designed to show that human language is constructions of the relations between logical and real events in the creative universe which refer to a particular point of view. In this view, a variety of verbal possibilities in the multiple worlds can be realized in the same proposition. For Whitehead the emergence of novelty in the function of proposition is an essential property of the creative universe. This paper will try to give a discussion to Whitehead's theory of proposition with regard to the emergence of nature. Especially I emphasize in this paper Whitehead's idea and meaning of proposition for the development of the creative advance of nature as one aspect of particular importance.

  • The purpose of this study is to understand the concept of publicness in social services. Recently, it has been argued that publicness be one of the key elements of social services even under the current social service marketization. Although publicness has been discussed in different ways in various academic areas, there is no consensus of what publicness really means, especially in social services. Therefore, reviewing discussions on publicness, this study intends to discover commonly shared aspects of publicness, and ultimately to suggest meanings of publicness in social services. This study also attempts to discuss whether different types of social service producers require different types of publicness under the context of welfare mix and social service marketization. The publicness in social services is related to various aspects: the scope of service recipients, trust toward social services, appropriate composition of services, social integration, role of government, and public accountability. Also it is suggested that the specific meaning and contents of publicness can be used in different ways for each social service producer, such as public, nonprofit, or profit sector. The study has academic and practical implications. This study provides the basis for further empirical studies on publicness academically and for implementation of publicness in the field of social services practically.

  • This study analyzed the changes in the industrial environment surrounding the Gumi region and the status of the industrial crisis in the Gumi area amid such changes. The Gumi region is experiencing a more turbulent period than ever in the environment changes at the international, national and local levels, such as the transition to the Fourth Industrial Revolution, the weakening of the competitiveness of key industries including mobile devices and displays, and the moving-out of core companies such as Samsung and LG Group. Accordingly, efforts have been made to diversify the industrial structure by fostering industry of automobile parts, high-tech medical devices and carbon materials to cope with and adapt to environmental changes at the regional level. However, the Gumi region is still locked in to the mono-cultural, large enterprise-dependent industrial structure centering on the mobile and display sectors, failing to overcome the regional industrial crisis and stagnating the overall local economy. The relocation of large companies began to increase in the 2010s, reducing the protection of large corporations against environmental changes at the corporate level. As a result, the crisis factors of small and mediumsized enterprises are gradually expanding to the national and international scale and working more complexly, which is beyond the level they can afford. So it is highly likely that the current industrial crisis will deepen. Therefore, it is necessary to strengthen the resilience to adapt to changes in the environment when it comes to overcoming the industrial crisis in Gumi region. To this end, it is necessary to improve innovation capabilities and diversify businesses based on convergence and complex technologies at the enterprise level, and to be selected as a special crisis response area aimed at creating an innovative ecosystem through autonomous resonance of companies and industries at the local level.

  • USN(Ubiquitous Sensor Network) is a core infrastructure that makes come true the u-life in the ubiquitous society through various services of area such as u-city and u-Health. Therefore, we need to reseach about the domestic standards to establish the core technique of USN. Currently, the status of USN standards is most of technical standard and reseach that are technology for sensor node implementation and a protocol for energy-efficient communication and interlock with existing network. But, Standard and reseach for sensor network, integration management of heterogeneous sensor networks for USN application, sensing data management and USN database structure definition such as application and middleware are weak level. In this paper, we researched for standard development of the domestic sensor network service and relevant standard analysis to configure SWE(Sensor Web Enablement) of OGC(Open Geospatial Consortium) for standarded plattform technoloy in part of the middleware. Also we researched that it's a connection between domestic TTA (Telecommunications Technology Association) standards and SWE Standard. Finally, we researched for standard service plattform architecture on sensor network through analysis on the possibility of applying OGC-based services platform.

  • Mass production system of most manufacturing companies has been supplying us with various useful needs in life for many years. It leads our life to live in comfortable and prosperous circumstances. And we can consider that the contributions of the mass production system to the reduction of different stratification in community remarkable . However, The needs of many clients in these days are various, different, and segmented. It is undesirable to consider every Product on the same basis anymore. So these new requirements of the customers let manufacturing companies be ready for the new production systems which are able to satisfy all the customers, but differently. In this aspects, the customization system could meet new needs of the customers. As we know, cost increase and flexibility matter for the production are main difficulties for the introduction to mass customization. However, to make arrangements for the mass customization systems of the firms is an indispensible factor for maintaining competitiveness and coping with new needs in the future market. We should remember that customers' needs in market will be changing, segmenting, and diversifying, continuously. For this purpose this thesis is tried for studying strategical approach methods of the mass customization.

  • This paper analyzes two cases of space tokenization, Meridio and QuantmRE, to explore the potential of tokenization as a new means of space financialization. Space tokenization is based on blockchain technology and security token offering (STO). Although some financial geographers noted the possible impact of blockchain technology on space financialization, it has not been examined in depth. Therefore, this paper demonstrates space tokenization cases in detail. Meridio and QuantmRE suggest financial structures that convert space into tokens based on fractional ownership transactions. QuantmRE, specifically, allows a homeowner to secure cash without either debt or ownership relinquishment through sales of tokenized home equity. As this method takes a form of sale transaction rather than a loan, it enables financial institutions to circumvent strengthened regulation on loans after the 2008 global financial crisis. Moreover, even "house poor" households, who own houses but lack cash due to excessive loans, can cash out from their properties through QuantmRE. As such, space tokenization enables financial institutions to overcome constrained conditions after the global financial crisis, thereby reproducing space financialization. Space tokenization also has the potential to geographically expand space financialization through stimulating investment in the depressed housing market.

  • The purpose of this study examined the feasibility and efficacy of a senior center-based diabetes self-management program applying action research approach. The cyclical action research method was applied for this study: plan, act, evaluate, and reflect in delivering three waves of the intervention program. Three waves of a 12 weeks-length small group diabetes self-management program were offered during the period of 15 months in a senior center in Seoul. Planning of $2^{nd}$ and $3^{rd}$ wave program were based on reflection of $1^{st}$ and $2^{nd}$ program evaluation respectively. Among the 46 participants, 93.48% (N=43) completed the program. The quantitative evaluation showed statistically significant improvement in HbA1C(p<.001), fasting plasma glucose(p<.001), BMI(p=.016), waist circumference(p=.001), systolic blood pressure(p=.036), diabetes self-management behavior(p<.001) and health knowledge(p=.008). Qualitative data revealed that individual management was very helpful in empowering and adhering for own diabetes care for the participants. Participants reported high satisfaction towards the program with mean satisfaction score of 65.12. Application of the Diabetes Self-management program with action study strategy was successful in community setting for improving participants' subjective and objective outcomes. Action research method guides the practitioner to tailor the program to respond for the participants and field needs.
