  • Satellites have provided the impetus for the orderly development of reliability engineering research and analysis because they tend to have complex systems and hence acute problems. They were instrumental in developing mathematical models for reliability, as well as design techniques to permit quantitative specification, prediction and measurement of reliability. Reliability engineering is based on implementing measures which insure an item will perform its mission successfully. The discipline of reliability engineering consists of two fundamental aspects; $(1^{st})$ paying attention to details, and $(2^{nd})$ handling uncertainties. This paper uses some of the basic concepts, formulas and examples of reliability theory in application. This paper emphasizes the practical reliability analysis of a Low Earth Orbit (LEO) Micro-satellite power subsystem. Approaches for specifying and allocating the reliability of each element of the power system so as to meet the overall power system reliability requirements, as well as to give detailed modeling and predicting of equipment/system reliability are introduced. The results are handled and analyzed to form the final reliability results for the satellite power system. The results show that the Electric Power Subsystem (EPS) reliability meets the requirements with quad microcontrollers (MC), two boards working as main and cold redundant while each board contains two MCs in a hot redundant.

  • In many construction projects, progress and efficiency are hampered by poor communication of discipline-specific models. For example, architects use 2D or 3D CAD models and builders use CPM diagrams, Gantt charts, and spreadsheets to show their view of the project. Nowadays, advanced computer visualization tools, 4D CAD or VR, can show these disparate models to understand cross-disciplinary impacts of design and construction decisions. In Korea, several leading companies have tried to apply these tools to their pilot projects from the design phase to the maintenance phase. These companies have expected that more project stakeholders could understand a construction schedule more quickly and completely with 4D visualization than with the traditional construction management tools. However, modeling of the 4D CAD or VR can be quite time-consuming and expensive to generate manually and has therefore limited the spread and use of these models. In order to adopt widely those models in construction industry, the areas that those tools could support to take large benefits in diverse functional areas of construction management need to be analyzed. In this study, researchers analyze the usefulness and limitations of the 4D models and VR in the construction industry, develop the strategy of application priority, and improve the 4D modeling method.

  • The purpose of this study is to present possibility about applying space design of urban theory focused on collective memory. Urban which is the final data of human's collective life has been recognized creative circumstances human collective is living. It can not think without collective from its motivation to problem of form as well as building as element which compose these cities. It is to recognize essential attribute of construction in the collective that think architecture with urban, and It means that recognize actuality of architecture that can talk as the most collective product that represent human. There was discussion for collective and urban. But, this problem was proceeded to clear human knowledge of architecture mainly in other discipline, and even if speak as field of architecture, it could just pass confined meaning by refering at process that clear several main aspects of architecture as doing not pass over more than it. Problem of form that is ultimate aspect of architecture remained by different thing still doing not combine with collective architecture, and occasionally happened the case that make collective of architecture and relation of form overly incommodiously reducing form by a tool for diagram, shape, figuration in the aspect of collective. This research study concept for memory collective in the urban and collective of architecture, and choose urban planning methodology and their work by specific example between Aldo Rosi and Rem Koolhaas dealing with architecture and urban, and present possibility about space design of urban.

  • In any subject area related to the provision of safety, failure is typically the most effective mechanism for evoking rapid reform and an introspective assessment of the accepted operating methods and standards within a professional body. In the realm of tall buildings the most notable failures in history, those of the WTC towers, widely accepted as fire induced failures, have not to any significant extent affected the way they are designed with respect to fire safety. This is clearly reflected in the surge in numbers of Tall Buildings being constructed since 2001. The combination of the magnitude and time-scale of the WTC investigation coupled with the absence of meaningful guidance resulting from it strongly hints at the outdatedness of current fire engineering practice as a discipline in the context of such advanced infrastructure. This is further reflected in the continual shift from prescriptive to performance based design in many parts of the world demonstrating an ever growing acceptance that these buildings are beyond the realm of applicability of prescriptive guidance. In order for true performance based engineering to occur however, specific performance goals need to be established for these structures. This work seeks to highlight the critical elements of a fire safety strategy for tall buildings and thus attempt to highlight some specific global performance objectives. A survey of tall building fire investigations is conducted in order to assess the effectiveness of current designs in meeting these objectives, and the current state-of-the-art of fire safety design guidance for tall structures is also analysed on these terms. The correct definition of the design fire for open plan compartments is identified as the critical knowledge gap that must be addressed in order to achieve tall building performance objectives and to provide truly innovative, robust fire safety for these unique structures.

  • An innovative inertial reactive armor is being developed through a multi-discipline project. Unlike the well-known explosive or non-explosive reactive armour that uses high-energy explosives or bulging effect, the proposed inertial reactive armour uses active disc elements that is set to rotate rapidly upon impact to effectively deflect and disrupt shaped charges and kinetic energy penetrators. The effectiveness of the proposed armour highly depends on the tangential velocity of the impact point on the rotating disc. However,for a single layer armour with an array of high-speed rotating discs, the tangential velocity is relatively low near the center of the disc and is not available between the gap of the discs. Therefore, it is necessary to configure the armor with double layers to increase the tangential velocity at the point of impact. This paper explores a multi-objective geometry design optimization for the double-layered armor using Nelder-Mead optimization algorithm and integration tools of the python programming language. The optimization objectives include maximizing both average tangential velocity and high tangential velocity areas and minimizing low tangential velocity area. The design parameters include the relative position (translation and rotation) of the disc element between two armor layers. The optimized design results in a significant increase of the average tangential velocity (38%), increase of the high tangential velocity area (71.3%), and decrease of the low tangential velocity area (86.2%) as comparing to the single layer armor.

  • This research is attempted to investigate Dongcheon-rock inscription- to understand symbolic meanings from inscribed texts and to find its construction purpose. For the investigation, 25 target areas were selected for field exploration and literature review regarding Dongcheon were also performed. Several design characteristics of Dongcheon are as follows: First, Dongcheon has four criteria according to creation purpose: residential type(家居地型), hermitage type(隱棲地型), nature excursion type(山水遊覽型), aesthetic scenery type(勝景型), moral training type(修身型) and spiritual discipline type(修道地型). This category shows that Dongcheon is constructed at residential area, shelters, and place for leisure, mortal training and spiritual discipline. Second, Dongcheon is also classified by its location: location on village entrance in a deep forest(深山同口型) and location on near stream(溪流隣接型); location on near stream has also two types(連繫型, 單一領域型): location on an independent territory and location horizontal ground(平地型). Through garden creators' managing their garden in forest, valley and scenic spots, they pursue utopia. Third, naming is a way to create new landscape places. By naming a certain natural landscape as Dongcheon, the landscape is symbolized as utopia, appearing fairyland. Designer's desire and thoughts are saturated in Dongcheon.

  • This study proposes an execution protocol for fashion therapy. Research on fashion therapy are limited and insufficient for the current need for the establishment of a fashion therapy theory. This study introduces cognitive behavior therapy, embodied cognition, and object relations theory as theories that underlie fashion therapy. A fashion therapy system model is provided based on the analysis of art therapy to explore its applicability to fashion therapy. The fashion therapy system model utilizes fashion items to managing pain and stress to better competence, encouragement and self-expression mechanisms to improve social, psychological, emotional and behavioral functions. In addition, 8 phases of the fashion therapy process (inquiry, forming rapport, assessment, goal-objective, observation, selection of strategy and design, practice, and the final evaluation and closing of fashion therapy) are suggested for developing a practical fashion therapy program. This study is to help overcome a negative perspective on fashion that provokes an excessive spending behavior and to make a practical contribution by creating more social value through fashion. The significance of the study is in the attempt to create an interdisciplinary approach of psychotherapy and fashion that can be extend into the fashion and textile discipline.

  • The underlying purpose of this paper is to interest scholars in 'Trade English'. 'Trade English' has to be recognized as one area of 'International Trade' disciplines and more studies have to be carried out with more attention from the scholars. Although there are many areas to be dealt with in 'Trade English', this paper discusses about the syllabus design of 'Trade English' from an educator's point of view. First of all, this paper reviews some theoretical background researches about needs analysis and syllabus design in 'Trade English' teaching and learning as ESP. With a systematic structure under the decent syllabus, selection and sequence of contents get clear and easier. Secondly, along with the rationals based on theoretical researches, how these theories are being or can be applied to the real classroom are discussed for further studies. A different syllabus would be designed according to needs analysis. In reality, the syllabus for practitioners who are doing their jobs in International Trade areas has to be definitely different from the one for pre-practitioners who are studying in International Trade areas at the tertiary education level. Namely, different learners present different needs and different needs make up the different syllabus. In order to provide these learners with the syllabus which can address their own needs, more researches or studies have to be done in the future. Since 'Trade English' is the discipline where two areas-International Trade and English as a second/foreign language-are mixed, the researches or studies also have to be carried out collaboratively by scholars from both areas.

  • The Quantum-dot Cellular Automata (QCA) can be considered as a candidate for the next generation digital logic implementation technology due to their small feature sizes and ultra low power consumption. Up to now, several designs using Uh technology have been proposed. However, we found not all of the designs function properly. Furthermore, no general design guidelines have been proposed so far. A straightforward extension of a simple functional design pattern may fail. This makes designing a large scale circuits using QCA technology an extremely time-consuming process. In this paper, we show several critical vulnerabilities related to unbalanced input paths to QCA gates and sneak noise paths in QCA interconnect structures. In order to make up the vulnerabilities, a disciplinary guideline will be proposed. Also, we present a fast adder which has been designed by the discipline, and verified to be functional by the simulation.
