The Web environment of the frontend domain is increasingly competitive to preempt the new standard of presentation layer. N-Screen, a service that enables users to seamlessly use one content in various devices in Korea, is competing for market preemption by recognizing it as a core service of the future. In the cloud computing, N-screen is a typical service type. However, most of the frontend research required for groupware in enterprise environments has been limited to responsive web design for the web and native apps for mobile. Gradually, the need for MVC design patterns is increasingly widening in enterprise environments to overcome the cultural differences of companies and to support one source multi-use strategy supporting multiple devices and development productivity. Therefore, in this study, we will analyze and design JPetStore with hybrid application design based on Spring MVC, e-government standard framework environment of next generation web standard, and provide reference model of frontend hybrid apps design in future enterprise environment.

This paper is about environment-based low-code and no-code execution platform and execution method that combines hybrid and native apps. In detail, this paper describes the Low-Code/No-Code execution structure that combines the advantages of hybrid and native apps. It supports the iPhone and Android phones simultaneously, supports various templates, and avoids developer-oriented development methods based on the production process of coding-free apps and the produced apps play the role of Java virtual machine (VM). The Low-Code /No-Code (LCNC) development platform is a visual integrated development environment that allows non-technical developers to drag and drop application components to develop mobile or web applications. It provides the functions to manage dependencies that are packaged into small modules such as widgets and dynamically loads when needed, to apply model-view-controller (MVC) pattern, and to handle document object model (DOM). In the Low-Code/No-Code system, the widget calls the AppOS API provided by the UCMS platform to deliver the necessary requests to AppOS. The AppOS API provides authentication/authorization, online to offline (O2O), commerce, messaging, social publishing, and vision. It includes providing the functionality of vision.

인류는 과학기술의 발전과 함께 의학기술도 눈부신 발전을 거듭해왔다. 그러나 과거에도 난치성 질환은 여전히 존재 하였듯이 지금도 난치성 질환이 존재하는데, 그 중 턱관절장애가 있다. 현재 의료선진국이라 불리는 대한민국 의료진들의 진단은 환자의 발언, 의사의 청음진단과 자를 이용한 진단, X-ray 촬영 진단 방식을 고수하며 시대에 뒤떨어지고 있다. 그렇기 때문에 환자의 정확한 증상 여부, 의사 본인의 진단 실력과 경력이 중요하고, 증상의 경중에 따른 진단 횟수의 증가 와 이로 인해 발생하는 의료비용은 막대하다. 본 연구에서는 이를 해결하기 위해 저작운동(최대폐구)시 교근에서 발생되는 근전도 신호를 %MVC를 통해 정량화하였다. 정량화된 근전도는 Cortex로 비교, 평가하여 턱관절 상태 평가 기준 지표를 확립할 것이다.

Human beings have made remarkable advances in medical technology as well as technological advances. However, as was the case in the past, incurable diseases still exist: temporo-mandibular joint (TMJ). The diagnosis of the Korean medical staff, currently called a "medical advance," is adhering to the outdated patient's comments, diagnosis using a doctor's auditory diagnosis and a ruler, and diagnosis of X-ray imaging. Therefore, it is important to have accurate patient symptoms, to have a doctor's own diagnosis and experience, to increase the number of diagnoses due to the severity of the symptoms, and to cover the costs of medical care. To solve this problem, the core conductive signal generated from the bridge was quantified through %MVC. Quantified EMG will be assessed and compared with Cortex to establish a jaw joint condition evaluation criterion.

본 논문에서는 이동 로봇의 동적환경에서 장애물과의 충돌없이 목표점에 도달하기 위한 새로운 방법을 제시하였다. 논문의 기본 아이디어는 목표점을 향해 이동한 거리와 장애물 들과의 충돌시간과의 관계를 특정평면에 표시하는 기존의 충돌회피지도(collision free map) 개념을 사용하였다. 그러나 기존의 충돌지도를 사용한 기법은 이동할 경로가 정해졌다는 전제하에 선속도와 각속도가 decoupling되어 nonholonomic 시스템에서 사용하기 어려운 단점을 가진다. 본 연구에서는 이러한 기존 충돌지도의 문제점을 해결하기 위해 장애물의 동적운동에 의한 충돌위치 및 예상충돌시간의 변화를 고려하여 동적충돌지도를 생성하는 방법을 제시하였다. 이 방법은 선속도 뿐만이 아니라 각속도의 가용성(feasibility)을 고려하기 위해 기존의 충돌지도에서 사용한 이동길이-서보시간 평면을 제시된 새로운 평면으로 투영하여 궤적계획을 하는 것으로 모든 해들이 닫힌 형태를 취하도옥 실시간 경로 및 궤적 계획기를 설계하였다.

In this paper we addressed a novel method of collision free motion planning of mobile robots under dynamic environments. The main idea of our paper follows the existing concept of collision free map which represents the relation, between collision time and the moving distance of the robot to the goal, on the characteristic plane. However, this existing method has the disadvantage because it assumes the fixed path which makes linear velocity and angular one decoupled, so it is difficult to use in nonholonomic system. To solve the problem of the existing collision map, we present DCM(dynamic collision map) concept which consider the estimated collision time as well as the collision position. The proposed method projects the plane of the travel length versus servo time, which is conventional in the existing method, into the new plane. Conclusively, our method takes the closed form of all solutions, which makes the real time path and the trajectory planner possible.

To avoid the problems of high complexity and low flexibility in Java based application Model–view–controller (MVC) framework is introduced to divide the whole application into model, view and controller, which can improve the software’s reusability and flexibility. Java is one of the leading software development languages. However, the development model of existing Java organizes without a structure, which mixes the code of data access, the processing of business logic and graphical user interface (GUI) layer together. As a result, it creates many problems for software developers, meanwhile; it could not meet the rapid development of application software any more. In this paper, we design and implement a Java MVC framework for developing desktop based application which can separate the data, view and control of the software.

Customer relationship management (CRM) has been as important to the banking industry at the start of the 21st century as it has been to any other industry.

Traditional MVC model is a monopoly-like patterns in response to the request, although there are a lot of advantages, but the performance of the layer is weak, and AJAX just make up for shortcomings in this regard.Ajax is the popular Web client technology, providing a asynchronous programming model by the adoption of Java Script and DHTML, so as to enhance the interactive web pages and the ability to respond so that the Web application offer the human-computer users a better experience. In this paper, it illustrates the development of Web applications by combination of both, and puts forward the reconstruction of the MVC pattern.

Approximation methods are best way to deal NP optimization problems and MVC is one of these. In this research paper we have presented a new extra fast approximation algorithm for solving MVC generally in all graphs. The proposed algorithm is named degree contribution algorithm (DCA), a new data structure proposed and employed in this algorithm, name degree contribution. It is first time in literature that such a sophisticated data structure for graphs is proposed which take account of whole graph for each node contribution value. All decisions regarding vertices are made on the basis of the proposed data structure. Effectiveness of DCA is shown by applying it to best available benchmarks and after large number of experiments worst approximation ratio recorded was 1.041 and an average approximation ratio was 1.005. These results show that algorithm can perform well in solving graphs faster as compared to other algorithms present.
