  • The fatigue crack propagation of random short fiber SMC composite material was investigated. In macroscopic viewpoint, SMC composite material was treated as isotropic material and was analyzed in terms of conventional fracture mechanics. Experiments were conducted on mode I and mixed respectively and various loading level was applied to each mode. Fatigue crack growth can be explained in three steps and most of fatigue life is consumed in initial crack growth. In this experiments, power law, i.e, da/dN=C(C.DELTA.K)$^{m}$ , between fatigue crack growth rate and stress intensity factor range, was valid and the value of the exponent m is about 10, which is much higher than that of other metals. Fracture mechanism was also investigated by SEM fractographic study.

  • Mechanical system dynamics plays an important role in the area of computational structural biology. Elastic network models (ENMs) for macromolecules (e.g., polymers, proteins, and nucleic acids such as DNA and RNA) have been developed to understand the relationship between their structure and biological function. For example. a protein, which is basically a folded polypeptide chain, can be simply modeled as a mass-spring system from the mechanical viewpoint. Since the conformational flexibility of a protein is dominantly subject to its chemical bond interactions (e.g., covalent bonds, salt bridges, and hydrogen bonds), these constraints can be modeled as linear spring connections between spatially proximal representatives in a variety of coarse-grained ENMs. Coarse-graining approaches enable one to simulate harmonic and anharmonic motions of large macromolecules in a PC, while all-atom based molecular dynamics (MD) simulation has been conventionally performed with an aid of supercomputer. A harmonic analysis of a macroscopic mechanical system, called normal mode analysis, has been adopted to analyze thermal fluctuations of a microscopic biological system around its equilibrium state. Furthermore, a structure-based system optimization, called elastic network interpolation, has been developed to predict nonlinear transition (or folding) pathways between two different functional states of a same macromolecule. The good agreement of simulation and experiment allows the employment of coarse-grained ENMs as a versatile tool for the study of macromolecular dynamics.

  • Tracing an evolutionary technological trajectory in the macroscopic viewpoint is useful for technology policy, but not for corporate technology and intellectual property strategy. Tackling this issue, recent bibliometric studies using patents and papers have made efforts to identify more specific and detailed technological trajectory. However, these studies cannot go beyond simple description of the past trajectory. Also, identification of technology fusion and evolution relies on experts judgments. We suggest a way of identifying microscopic evolutionary technological trajectories by combining patent citation network analysis with dynamic technology tree. Also, using new indicators of generality, diversity and novelty, we can detect key technologies that can be a starting point of next generation technology and derivative technology. HVDC(High Voltage DC transmission) system technology is exemplified.

  • Capital punishment is a system which is not finished simply as one of interim penalty but does away with one person's existence eternally. It is not only opposite to the existential humanism but also contrary to social welfare's goal like social integration. Therefore, this study tries to find out the issues related to capital punishment and further tries to draw out the rightness of capital punishment abolition by critically reviewing the capital punishment system on the basis of the value and philosophy of correctional welfare. In brief, capital punishment is possible only when we negate the inviolable fundamental right which is called life right, and deny the human life existence which surpasses space and time. As long as we can not deny the macroscopic viewpoint to search out the basis of human behavior in the social system which is called culture and society, capital punishment system is contrary to the philosophy of welfare that total society is responsible for guiding members of society to pursue self realization on the basis of value like social solidarity and human dignity. Also, it is against the objective of correctional welfare to head toward special prevention by positive correction and rehabilitation. Capital punishment system ought to be abolished properly.

  • The objective of this study is to present the academic implications and developmental direction of the police assigned for special guard system through big data analysis on the objective and macroscopic viewpoint of the media. As research method, this study conducted the analysis on 'police assigned for special guard' and the analysis of related words that would visualize the keywords highly related to keyword trend and news. Also, after dividing the period into the 1990s, 2000s, and 2010s, the number of relevant articles in each period was drawn for understanding the flow. In the results of this study, the perception of media report of police assigned for special guard was about the recruitment of police assigned for special guard, and relevant events/accidents, which showed the coexistence of positive interest in the recruitment of police assigned for special guard and negative image of events/accidents related to police assigned for special guard. As a result, however, the necessity and demand for police assigned for special guard are increasing. Thus, the police assigned for special guard should be engaged in work after carefully thinking of its role in charge of ethical responsibility and safety as an axis for maintaining the national safety and social order.

  • The objective of Value Engineering (VE) is to derive the optimal value at the most efficient life cycle cost, comprising three stages: Pre-Study, Study, and Post-Study. In this study, we propose a method for information collection and analysis during planned site visit surveys in the preparation stage of VE. The 3D spatial model, created using a drone, facilitated observation and analysis of the study area from various angles, both from the center and the outside. Additionally, through the utilization of drones, we conducted on-site investigations of the research area's 3D spatial model, enabling a macroscopic perspective previously only feasible through a microscopic viewpoint during planned site visits in the pre-study phase. Furthermore, the utilization of actual spatial data obtained from observations allowed for real-time information verification during Design VE workshops, enhancing the efficiency and reliability of the VE project.

  • This study was conducted to establish a service philosophy as a major ideology in the New Economy and Society. The service philosophy, which is the ideological foundation to lead the service economy era, should be an idea that can develop the new economy society, reflecting the nature principle of the universe and human being. The service philosophy was derived based on the study of the human representative ideology and the study of the new economy and service essence. A good idea must be consistent with the principles of the universe and be consistent with the essence of the human representative ideology, so that it reflects the core principles of the universe and the core of human representative ideas. In addition, the central idea should reflect the changes of the New Economy Society in the future. Therefore, the essence of the service and the change of the New Economy Society were analyzed. We analyzed the social and philosophical significance of the macroscopic cosmology and the microscopic quantum theory of modern physics. We analyzed the essence of Oriental and Western representative ideas and derived implications of these ideas from the viewpoint of modern society where service is central. Based on the essence principle of the universe and human, we have established the service philosophy structure and derived the human, historical, social, economic, and managerial aspects of service philosophy. The structure of the derived service philosophy was presented, and discussions were conducted for future research.

The Theory of Yin and Yang and the Five Elements of Mohism - Focusing on the Comparison with Hundred Schools of Thought (묵가(墨家)의 음양오행론(陰陽五行論) - 제가(諸家)와의 비교를 중심으로 -)

  • In this paper, the discussion on Yin and Yang and the Five Elements in Mohism is examined through the comparison with Hundred Schools of Thought. The ideas of School of Naturalists including Zou Yan or those of the Five Elements were fundamentally for the purpose of observing the regularity of changing dynasty. However, this perspective had not been emphasized as a subject of Contention of a Hundred Schools of Thought until the end of the Era of Warring States. Even though it is true that Hundred Schools of Thought applied the theory of Yin and Yang and the Five Elements in common based on the understanding of the idea, but it failed to be connected to each ideological system. The fundamental reason for this can be found in the difference between the awareness of a reality and the concept of history in Hundred Schools of Thought. Where were the characteristics and reasonable opinions of the theory of Yin and Yang and the Five Elements in Mohism from? The most important feature of Mohism is to form independent, collective, cooperative groups based on the people of lower classes at that time and to consider God an ideological presumption. Therefore, in reality, it concentrated only on sociopolitical stability and maintenance of their own labor activities, and it was difficult for them to focus on an objective regularity of a national system or change of dynasty. In addition, due to the characteristics of individual groups, it was hard to have a macroscopic viewpoint not only on a national system, but also on others as in Zou Yan's Dae-gu-ju-seol(大九州說). With respect to this, at least, Xunzi, before the unification, gives a valid criticism. In the end, the effort to design a new political system and to secure ideological legitimacy on the assumption of the unification of the nations of the Warring States period became more specific through the edition of $L{\ddot{u}}shi$ Chunqiu (呂氏春秋), so-called Mixed School(雜家) or Synthesized School(綜合家).
