  • Recently, the West's interest on Buddhism has been uprising. If the interest on Buddhism is especially from Western intellectuals, it will surely be the motive to change, the future of Western society. Actually, while the West has been interested in the material civilization on the basis of Christianity, the East has been pursuing after the spiritual culture on the basis of Buddhism. However, what does it mean that many of civilized westerners have come to dislike the manner of scientific pursuit and strict rationality which made them wealthy materially\ulcorner It means that they have felt their ideologies which is based on the Christian culture, has met an end or at least they have started to get interested in the Eastern ideology, 'Buddhism'. Particularly, if we agree that industrial design is a field of basis on the stringent rationality, and is a field of applied science on the basis of technology and production, it surely must have rather been influenced by Christian culture than Buddhism. But regardless of material richness by Christian culture, some Western intellectuals'secession from christianity means that their pursuit of material civilization doesn't help much in chasing after human original happiness. Instead, they are charmed by the fact that their mental illness problem, which is the result of the incessant pursuit of materialism, can be salved more 'scientifically'rather by Buddhism than Christianity. Compared with the westerners'spiritual unhappiness by the strong pursuit of material, Buddhism lowers their passion for material and help to lead their lives happily with least'pursuit of materialism. In this sense, I insist that we need to study'Design'from a viewpoint of Buddhist idea.

  • This paper considers the combination of cyclic and axial loads to investigate the hysteretic performance of H-section 6061-T6 aluminum alloy members. The hysteretic performance of aluminum alloy members is the basis for the seismic performance of aluminum alloy structures. Despite the prevalence of aluminum alloy reticulated shells structures worldwide, research into the seismic performance of aluminum alloy structures remains inadequate. To address this deficiency, we design and conduct cyclic axial load testing of three H-section members based on a reliable testing system. The influence of slenderness ratios and bending direction on the failure form, bearing capacity, and stiffness degradation of each member are analyzed. The experiment results show that overall buckling dominates the failure mechanism of all test members before local buckling occurs. As the load increases after overall buckling, the plasticity of the member develops, finally leading to local buckling and fracture failure. The results illustrate that the plasticity development of the local buckling position is the main reason for the stiffness degradation and failure of the member. Additionally, with the increase of the slenderness ratio, the energy-dissipation capacity and stiffness of the member decrease significantly. Simultaneously, a finite element model based on the Chaboche hybrid strengthening model is established according to the experiment, and the rationality of the constitutive model and validity of the finite element simulation method are verified. The parameter analysis of twenty-four members with different sections, slenderness ratios, bending directions, and boundary conditions are also carried out. Results show that the section size and boundary condition of the member have a significant influence on stiffness degradation and energy dissipation capacity. Based on the above, the appropriate material constitutive relationship and analysis method of H-section aluminum alloy members under cyclic loading are determined, providing a reference for the seismic design of aluminum alloy structures.

  • Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies.

  • In this paper, a cable-driven endoscopic manipulator (CEM) is designed for the Chinese latest compact fusion reactor. The whole CEM arm is more than 3000 mm long and includes end vision tools, an endoscopic manipulator/control system, a feeding system, a drag chain system, support systems, a neutron shield door, etc. It can cover a range of ±45° of the vacuum chamber by working in a wrap-around mode, etc., to meet the need for observation at any position and angle. By placing all drive motors in the end drive box via a cable drive, cooling, and radiation protection of the entire robot can be facilitated. To address the CEM motion control problem, a discrete trajectory tracking method is proposed. By restricting each joint of the CEM to the target curve through segmental fitting, the trajectory tracking control is completed. To avoid the joint rotation angle overrun, a joint limit rotation angle optimization method is proposed based on the equivalent rod length principle. Finally, the CEM simulation system is established. The rationality of the structure design and the effectiveness of the motion control algorithm are verified by the simulation.

  • The stepping stone of the study is provided through understanding the transformation of the cultural value with the paradigm shift at the turning point of late 20th century and examining the cultural relationaship between the East and the West. By researching the oriental and occidental culture in terms of the origin formation relation and differences which should be divided into broad branches that is natural ideological formative and spatial aspects and so forth. This paper makes it possible to understand the fundamental differences and relativities between two divergent cultures by way of analyzing the architecture in plastic and cognitive aspects to residential space. this study intends to elucidate common traits of korean traditional architecture and that of the Occident and the discrepancies of their attitudes toward nature and space. In Western civilization they used to consider architecture as a physical organization while the oriental people consider it a object what is so of itself. The former concentrated on the functional rationality of scientific technology with the uncontextual propensity which does not consider natural environment the latter could reach the naturalness more harmonious to environment. What counts in the upcoming age of coexistence of Globalism that emphasizes the worlds universality and Nationalism that sticks to local cultural characteristics is to establish the new value system and identity based upon natural order and organic quality. As a result we could recognize the organic quality as a cosmic order could be a valid means to achieve the globalization of our culture through the compatibility between gap and common ground of both cultural sphere.

  • 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'.

  • Purpose: This study aimed to explore the rationality for and countermeasures against the use of prehospital patient restraint (PPR) techniques in efforts to limit violent behavior toward 119 emergency medical technicians (EMTs). Methods: Previous countermeasures to limit violent behavior toward 119 EMTs and medical personnel were focused on strict reactive and passive proactive responses. However, those in support of the countermeasures do not believe that violent and criminal behavior can be limited or extinguished by strengthening the punishment unconditionally. Results: When it comes to the far-reaching effects of stigmatization on people who engage in violent and criminal behavior, it is possible that unconditional punishment leads to more crime, increases the costs of imprisonment, and consequently, adds to the financial burden of the government. Conclusion: Thus, we are faced with an urgent need to prepare legal grounds for the use of PPR techniques by 119 EMTs for agitated or combative patients only, with direct medical oversight. Moreover, the legal foundation for the use of PPR techniques also needs to be established for emergency medical personnel. The use of PPR techniques not only ensures the safety of emergency medical services personnel, but also protects patients from injuring themselves and others.

  • The health condition of of deep water high pile foundation is vital to the safe operation of bridges. However, pier foundations are vulnerable to damage in deep water due to exposure to sea torrents and corrosive environments over an extended period. In this paper, combined with aninvestigation and analysis of the typical damage characteristics of main pier group pile foundations, we study the safety monitoring and real-time early warning technology of the deep water high pile foundations, we propose an early warning index item and early warning threshold of deep water high pile foundation by utilizing a numerical simulation analysis and referring to domestic and foreign standards and literature. First, we combine the characteristics of structures and draw on more mature evaluation theories and experience in civil engineering-related fields such as dam and bridge engineering. Then, we establish a scheme consisting of a Early Warning Index Systemand evaluation model based on the analytic hierarchy process and constant weight evaluation method and apply the research results to a project based on the Jiashao bridge in Zhejiang province, China. Finally, we verify the rationality and reliability of the Early Warning Index Systemof the Deep Water High Pile Foundations.

  • The emergence of convergence has been the cause of development of the industry more complex and difficult by continually changing business environment and the destruction of the business area. The government-initiatives approach shows the limits to foster the new industries in needs of service-oriented ecosystem. In this study, we propose the service model as service-based approach for the development of new industries derived through the convergence inter-industry. While business model is defined based on the company's temporary and piecemeal activities, service model is the concept of dynamic and continuous that includes national, industrial, corporate level. In order to derive the service model, to identify current problems and issues with the public and the private sector is first. Then design the roadmap for the implementation of the desired shape through strategy from optimal rationality and long-term strategy. In this study, we define a service model, and consider when establishing a service model for three dimensional(national, industrial, corporate level) through analyzed by 3Level Service Model. And we also consider characteristics of the service model and approach, present the case of 'New Transit Card Services in Seoul'.

  • Rationality only based on human experience and visuals takes huge toll on nation at the time of disasters. Accordingly, it is required to convert its system into national disaster-managing system based on governmental departments effective cooperation against catastrophic emergencies. Thus, this manuscript rejects empirical model of calamity measures and provides substituting prototype based on u-Gov which utilizes UT service from the developed countries' cases. Moreover, in order to provide nation's administrative services, the paper suggests alternative for politic issues which realizes a new incorporated control towel reflecting policies.
