Interlocking software used in the electronic interlocking has been implemented through the structured approach until now. But there was the demerit that interlocking software has some problem in the standardization and the maintenance because of the limit in structured approach. Object-Oriented method overcoming this demerit was specified in the design step and the analysis step. There were object model, dynamic model and functional model in the analysis step and there were also two steps which were system design and object design in the design step. In this paper, Interlocking software was designed using Object-Oriented method to improve the standardization and the maintenance of the electronic interlocking. The electronic interlocking was analyzed with object modeling, dynamic modeling and functional modeling.

Purpose : To provide a convenient framework for PNF practice, we reviewed the relationship between ICF framework and PNF framework. Methods : We reviewed literatures related with ICF and PNF. Results : ICF model is useful tool for physical therapist who is working in PNF to identify the interactions the components of individual's health, especially the relationship between functioning and disability. A framework for PNF is philosophy which included the concept, functional approach. It is essential to identify primary activity limitation and causal impairment in PNF field and evaluate the their relationship. The ICF model can be used to classify the examination information. Next step is to prioritize the activity limitation and then evaluate the interrelationships among each components of the ICF framework. Conclusions : ICF model guides physical therapist in PNF practice to identify patient problems and evaluate the interrelationship of components of their health. This model is logical framework to directs functional approach as PNF philosophy to be approached the goal.

In this paper, a design approch is presented for a concurrent self-diagnosable microprocessor. An efficient diagnostic procedure to dynamically test the processor functional units decomposed by each insturction, concurrently with a program under execution is suggested. The basic goals of the proposed design approach are the low hardware overhead, no increase in the pin count and the minimal change of the initial design concepts on conventional microprocessors. The results of the performance of the suggested self-diagnosing hardware for an 8080 type microprocessor show that the suggested diagnosis scheme would be efficiently applicable, since diagnosing the processor functional units can be completed in a reasonably short time with the execution of an arbitrarily chosen sample program.

In this paper the construction of a model that represents the behavior of an Electric Vehicle is described. Both the mechanical and the electric traction systems are represented using Multi-Bond Graph structural approach suited to model large scale physical systems. Then the model of the controllers, represented with a functional approach, is included giving rise to an integrated model which exploits the advantages of both approaches. Simulation and experimental results are aimed to illustrate the electromechanical interaction and to validate the proposal.

Developers often use cross-platform frameworks to create mobile apps that can run on multiple platforms with minimal code changes. However, these frameworks may not suit all the needs of a specific app, so developers may also use native APIs to add platform-specific features. This method eventually dilutes the advantages of cross-platform development methodology that aims to reduce development costs and time, and often leads to a decision to return back to the original native mobile development methodology. In this study, we explore a different approach: combining different cross-platform tools to develop a storybook mobile app that meets various requirements. We have demonstrated that integrating two cross-platform solutions can be used reliably to develop complex mobile applications. However, we also report that this approach can introduce unforeseen issues such as sandbox redundancy, unexpected functional burdens, and redundant permission requests. Despite these challenges, we believe that combining two cross-platform solutions can be applied to a variety of functional and performance requirements, enabling the development of more sophisticated mobile applications at lower costs and with shorter development timelines than traditional mobile app development methodologies.

A well organized system requirements provide a solid basis of achiving a successful project and are effective methods of communication among stakeholders. We illustrate and propose a 'System Requirement Development Framework' to develop correct requirements as a methodical approach. We first organize a 'Requirement Development Process' and then establish a 'Non-Functional Requirements Principle'. On these basis, we next propose a 'Requirement Development Guideline' from a perspective of 'Functional Requirement', 'Non-Functional Requirement' and 'Triage' in advanced stages. We also verify and evaluate the suitability of our proposed 'System Requirement Development Framework' by applying it to several projects.

To cope with the challenge from global market characterized by frequent changes in requirements, manufacturing enterprise should be able to promptly adjust its manufacturing system accordingly. Therefore, it is important to provide manufacturing system designer with an appropriate methodology to (re-)design a manufacturing system subject to requirements change. Axiomatic design theory focuses design activity mainly on functional consideration rather than physical, and has been known as effective especially in the conceptual design phase. This paper introduces an approach to apply the axiomatic design principle to manufacturing system design. It is shown that a new design solution can be reached quickly by finding design parameters for the added or revised functional requirements and thus achieving a set of functional requirements as well as design parameters that satisfy the independence axiom. Some illustrative examples are also given.

[ $C\u{a}dariu$ ] and Radu applied the fixed point method to the investigation of Cauchy and Jensen functional equations. In this paper, we adopt the idea of $C\u{a}dariu$ and Radu to prove the Hyers-Ulam-Rassias stability of the quadratic functional equation for a large class of functions from a vector space into a complete ${\gamma}-normed$ space.

Functional neurology is a function-oriented clinical neurology with a focus on the viability, functionality, and balance of the neurologic system, which may be considered as a form of yin-yang balance medicine like Korean medicine. While it incorporates knowledge systems such as developmental neurology, neuropsychology, comparative neuroanatomy, and others, it views the neurologic system and the body as an individually different, self-regulating mechanism with the help of the active balancing mechanism within the nervous system and between the individual and the environment, which view is at the core of its effort to improve and serve the human dignity based on the best possible functioning nervous system. This article reviews core concepts of the functional neurology, discusses yin-yang balance medicine perspectives and clinical applications of it.

New types of lariat type crown ethers containing peptide sidearms were prepared by using a novel strategy employing single electron transfer (SET)-induced photocyclization reactions of $\alpha$-silylether terminated phthalimides. Reactions of chiral substrates in this series produced diastereomeric mixtures of crown ether products as a result of the formation of new stereogenic center generation in the photocyclization process.
