  • Objectives: This study was performed to review the research trends in the treatment of anorexia nervosa (AN) in Traditional Chinese Medicine (TCM). Methods: Studies were searched through The China National Knowledge Infrastructure (CNKI) database. The search term for the subject were 'Eating Disorder', and 'Anorexia Nervosa'. Clinical research that conducted TCM treatment for AN patients were included. Studies were analyze according to study design, therapy method, diagnostic criteria, population and intervention. Results: 23 articles were selected. According to study design, studies were classified into two randomized controlled trial (RCT), three single group before-and-after studies, and 18 case reports. According to therapy method, they included 19 herbal medicine studies, two acupuncture treatment studies, and two complex treatment studies. The most common pattern identification was 'liver depression with spleen deficiency' (肝鬱脾虛), and the most used herb was 'Root of Bupleurum falcatum' (柴胡). Most of the studies showed effective results in increasing appetite and weight. Conclusions: The results of our study demonstrate that TCM treatments for AN has been effective in alleviating chief symptoms. However, in terms of evidence-based medicine, lack of RCT on TCM treatments for AN and absence of objective diagnostic criteria in case reports are limitations. Therefore well-designed further clinical studies should be performed based on the results of this study are recommended.

  • This paper presents a circuit design far clamping the overvoltages across the GTOs in three-level GTO inverters. The proposed circuit has two roles as follows; one is to minimize the power dissipation in each GTO. It can be achieved by clamping the overvoltage to half that of the DC-link voltage as exactly as possible. The other is to get blocking voltage balancing between the inner GTOs and the outer GTOs.

  • This paper suggests a control method for efficient topology/parameter evolution in a bond-graph-based GP design framework that automatically synthesizes designs for multi-domain, lumped parameter dynamic systems, We adopt a hierarchical breeding control mechanism with fitness-level-dependent differences to obtain better balancing of topology/parameter search - biased toward topological changes at low fitness levels, and toward parameter changes at high fitness levels. As a testbed for this approach, an eigenvalue assignment problem, which is to find bond graph models exhibiting minimal distance errors from target sets of eigenvalues, was tested and showed improved performance for various sets of eigenvalues.

  • In this study, performance design programs for components of a turbopump unit (TPU) in a Liquid Rocket Engine (LRE), that has non-cryogenic centrifugal pumps and 1-stage impulse turbine with partial admission nozzle, were developed. The programs were integrated in a TPU module by balancing the mass flow rate for pump-turbine power, and the module was inserted into the LRE system conceptual design program. The fundamental design conditions, satisfying LRE system requirements and minimum mass flow rate condition of gasgenerator, were found and compared with data from a Russian liquid rocket engine.

  • Process of thinking on the form in product design includes the process in which unclear requirements are transformed into defined concepts, and the process in which the design as a form conforming to the concepts in conc1uded.(The former is called fconceptualizationJ which deals with abstract matters, and the latter "manipulation of the formJ which deals with more embodied matters) In conceptualization process the operation which transform the diverse requirements in the initial phase of de\ulcornersign to related linguistic expressions or to an image that directly suggests the form is executed. In the process of manipulation of the form the transformation to design as the description of relationships between the formal elements of the design solution resulted from the transformed requirements. It is the job of selecting the most suitable formal elements, balancing the relationships between them, out 01 the possibilities that reside in the individual attributes of formal elements, and finally leading to the design as the end solution. This writing focuses down to the wilfulness and ambiguity of design, and the diversity of design solution after the requirements, formal elements, and the process of relating the formal attributes to each other is built up the two phases.ases.

  • This paper introduces the process for Multi-objective Optimization Framework (MOF) which mediates multiple conflicting design targets. Even though the extensive researches have shown the benefits of optimization in engineering and design disciplines, most optimizations have been limited to the performance-related targets or the single-objective optimization which seek optimum solution within one design parameter. In design practice, however, designers should consider the multiple parameters whose resultant purposes are conflicting. The MOF is a BIM-integrated and simulation-based parametric workflow capable of optimizing the configuration of building components by using performance and non-performance driven measure to satisfy requirements including build programs, climate-based daylighting, occupant's experience, construction cost and etc. The MOF will generate, evaluate all different possible configurations within the predefined each parameter, present the most optimized set of solution, and then feed BIM environment to minimize data loss across software platform. This paper illustrates how Multi-objective optimization methodology can be utilized in design practice by integrating advanced simulation, optimization algorithm and BIM.

  • This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

  • To realize the U-healthcare system, the mobile patient monitoring system is of the essence. In this monitoring system, a patient's real-time data on biometrics and location must be transferred to predeterminate destination server ceaselessly. As the number of mobile patients increases steadily or mobile patients are moving into some specific area, the load balancing solution to real-time data congestion problem is needed. In this paper, we propose a new mobile patient monitoring system with Torus topology where three layers are connected hierarchically and the intermediate layer takes charge of priority-based load balancing. For the formalized design and verification of proposed system, we describe the overall structure with connectivity among its components and implement major components in pseudo-code by adopting a system specification-based approach. This approach makes the design and verification of our mobile patient monitoring system more flexible and accurate.

  • In the work of contemporary spatialization, the meaning of program is being an important conceptual element beyond simple functional dimension. The design of this diagram allows to balance among changing programs, and it comes into the spotlight as a medium, which links the virtual to the reality as embodying the virtual, which is not embodied realistically, realistically through the design process. In other words, this method is attracting the public attention as a design tool which can concentrate on design process rather than a fixed tool. This study focuses on the role of balancing among mixed programs and the diagram as a design tool. Therefore, the purpose of this study is to analyze and research the work of spatialization, which apply to diagrams of contemporary designers, is to identify operating mechanism and then is to examine the characteristics and importance of them.

  • A multi-stage reciprocating air compressor has many pistons and conneting rods to one crank throw, while a general engine has one connecting rod. Those make its design hard to apply balance weight design method generally using in an engine design, This study introduces a modified balance weight design method in order to calculate the unbalanced inertia properly. Vibration tests on V/W type air compressor have been conducted to prove the usefulness of design program. It is confirmed that the proposed program is applicable to design of balance weight.
