  • This paper represents the analysis and design of the generic mission operations system for next generation satellite mission. In the past, mission operations systems were developed by their own mission requirements respectively. However, these systems have the similar architecture and common functions. Mission operations systems, in general, consist of mission independent module and mission specific module. In this paper, the generic framework for the mission scheduling and automation are introduced and analyzed. Using these generic frameworks, the risk and cost for operations system development can be reduced significantly. And, these frameworks might be used for the core technology in the development of mission operations system in the future.

  • In this paper, we present an iterative learning control (ILC) framework for tracking problems with predefined data points that are desired points at certain time instants. To design ILC systems for such problems, a new ILC scheme is proposed to produce output curves that pass close to the desired points. Unlike traditional ILC approaches, an algorithm will be developed in which the control signals are generated by solving an optimal ILC problem with respect to the desired sampling points. In another word, it is a direct approach for the multiple points tracking ILC control problem where we do not need to divide the tracking problem into two steps separately as trajectory planning and ILC controller.The strength of the proposed formulation is the methodology to obtain a control signal through learning law only considering the given data points and dynamic system, instead of following the direction of tracking a prior identified trajectory. The key advantage of the proposed approach is to significantly reduce the computational cost. Finally, simulation results will be introduced to confirm the effectiveness of proposed scheme.

  • This research has acquired preliminary information about the existing conditions and understanding of members regarding time management for members in the architectural field. The goal of this research is to construct a basis for the time management education framework in architectural field in the future. This research mainly focuses on following questions based on limited objectives: Do groups of academics and professionals have understanding and knowledge of time management? Can the level of an individual's scheduling techniques be correlated to the patterns of knowledge and understanding of time management principles and practices? Can the time management practice status in individual's working environment be correlated to the patterns of knowledge and understanding of time management principles and practices? Can an individual's self-confidence level be correlated to the patterns of knowledge and understanding of time management principles and practices? Data have been collected through comprehensive questionnaires given to academics and professionals in United States. By means of statistical analysis, the hidden patterns, deficiencies and relationships in attitudes about time management have been revealed. The statistical analysis has produced conclusions that, among several subdivisions, self-discipline and planning have strong relationships and confidence, personal organization, control, and information gathering subdivisions have certain relationships with objectives of time management education in this research.

  • This paper proposes an object-oriented conceptual information model of mechanical assemblies, named open assembly model (OAM). The proposed assembly model primarily defines hierarchical relationships between parts and subassemblies. Together with the assembly hierarchy. the model also provides a way to represent tolerances, kinematic information, and parametric assembly constraints. Relational information such as mating conditions and degree of freedom between parts and subassemblies is captured via assembly features and relationships thereof. The information model is described using class diagrams of the Unified Modeling Language (UML), and instance diagrams are used to exemplify the proposed information model. The conceptual model presented in this paper is an integrated information model for assembly representation, which could supply necessary information for tolerance analysis and synthesis, kinematic simulation, and assembly simulation. Such a conceptual information model plays an important role for the exchange of information between modeling, analysis and planning systems. Hence, the proposed model could serve as a framework for developing data exchange standards of mechanical assemblies. The proposed model is demonstrated through a case study of a planetary gear assembly.

  • This study investigates the physical characteristics of indoor rest zones using the Space Syntax Method. A conceptual framework is based on analysis of design works presented in competitions(544 rest zones of 24 buildings on 7 campuses). The analysis on the unit type of rest zones showed that they were mostly available as open type, followed by semi-open type and outdoor rest places. On the other hand, by classifying the shape of whole building into traffic lines and nodal points, it was found that the buildings with 3 or more traffic lines have lower availability than others, because the buildings required more nodal points along a little higher complexity and zoning formed at increased nodal points between building masses. The analysis on the location of rest zones on traffic lines showed that hall type was most excellent in the level of availability. Finally, the analysis on the floor height showed that hall-like open rest places and outdoor places like rooftop garden functioned as a factor to enhance the integration of different spaces. In conclusion, this research will help the follow-up studies make spatial creation planning that may enhance the spatial efficiency and availability of Indoor rest zones on the campus.

  • The concept of Regional Innovation System(RIS) has been developed with the accumulation of empirical research and the reflection on the political and economic environments. It is widely used as a nonnative concept to tackle the problem of regional disparities by enhancing regional innovative development. However, it seems that there is a gap between the theoretical framework of RIS and its actual application in reality. This paper attempts to extend our knowledge about RIS with critical viewpoint. It tries to unravel some values that RIS implies and its theoretical limitations, which were found through the evolution of RIS such as its theoretical roots, the development of its research and policy; and an example of its building in practice.

  • Palliative medicine has shown demonstrated benefit for patients with serious illness, their families, and hospital systems. As such, the demand for palliative care services is growing at a fast pace, and health care facilities frequently struggle to develop and implement effective and sustainable methods of providing this care. As with any new system, challenges and barriers naturally exist to instituting palliative care. Undertaking careful assessment, planning, and resource allocation can provide the greatest likelihood of success when developing these novel yet much needed models of care. This summary paper offers a qualitative overview of the potential benefits and the rationale to implement robust palliative care systems. We briefly review the history of palliative medicine in the broadest sense and address several seminal works from the US palliative care literature. Core practices to establish and advance palliative medicine are suggested. Commentary is provided on some of the particular barriers to palliative system development that may need to be addressed in the context of Korean medical culture. Collectively, we hope this overview can contribute to a framework within which such research and development can occur, leading to increasingly effective and sustainable palliative medicine in Korea.
