Commercially available software packages permit to position human models of various geometries in practical scenarios while respecting the anatomical constraints of the skeletal joints and of the bulk of the bodies. Beyond such features, the PAM-Comfort(sup)TM software has been conceived to provide direct access to the muscular forces needed by humans to perform physical actions where muscle force is required. The PAM-Comfort(sup)TM human models are made of multi-body linked anatomical skeletons, equipped with finite elements of the relevant skeletal muscles. The hyper-static problem of determination of muscle forces is solved by optimisation technique. Voluntary stiffening of muscles can be added to the basic contraction levels needed to perform a specific task. The calculated muscle forces obey Hills model. The model and software have been applied in several interesting scenarios of various fields of application, such as car industry, handling of equipment and sports activities.

Software defined technology (SDx), which defines the IT infrastructure based on software and controls that are not dependent on a specific hardware, and provides a rapid and flexible IT infrastructure, is increasing. SDx features centralized control, a common commercial product infrastructure, hardware-software dualization, and programmability. With the advent of the fourth industrial revolution, in which various application services are emerging based on IT infrastructure, interest in SDx is gradually increasing as the need for infrastructure flexibility and an agile business environment is increasing. This paper reviews the market trends of software defined anything using SDx and the trends of major vendors.

Recently, in terms of the future education, the need of the software education according to the 4th industrial revolution and the need of the ESG(environmental, social and governance) education according to social requests for sustainability are increasing at the same time. There may be a number of ways to satisfy the needs at the same time. In this paper, as an effort for meaningful implementation of the future education, a case study on the ESG engineering education based on the software education for community youth was analyzed and a future development direction was suggested. This ESG engineering education deals with the development and application of the program considering terms of target, method and implementation in order to enhance its systematicity and using physical computing and upcycling methods and a collaborative education support system. To verify the education program, a survey is performed and analyzed. Through this, the basis of an software education-based ESG engineering education model was established.

본 논문에서는 사용자에게 편의성을 제공하며 기존 물물거래 시스템의 단점을 보완한 웹기반의 물물교환 시스템을 제안한다. 대부분 사람들이 중고거래나 필요 없는 물품에 대해 판매를 하는 목적은 자신에게 필요 없는 물건을 처리하고 필요한 물건을 구매하기 위해서이다. 이러한 사용자들의 관점에서 보았을 때, 필요한 물건을 얻기까지의 과정이 장시간 걸린다는 단점이 있으며, 사람들이 필요 없는 물건을 버려 낭비되고 과소비되는 경우도 있다. 이러한 문제를 해결해서 필요 없는 물건을 필요로 하는 사람과 물물교환을 하여 불필요한 소비를 줄이고 필요한 제품을 서로 쉽게 찾고 교환할 수 있도록 사용자에게 편의성을 제공하는 물물교환 시스템을 제안한다.

The SDR(Software Defined Radio) system for hardware and software must be an open structure to various system standards. It should also provide a capability of distributed processing, object-orientedness, and software controllability. It implies that the software to be used in the SDR system should provide the openness such that it can operate independently of a given hardware platform. In order to achieve these goals, the SDR system tends to modularization for increasing hardware reuse and design flexibility, which provides the system reconfigurability. In this paper, we implemented a base station with proposed an open architecture of a Smart Antenna Base Station(SABS) and Smart Antenna APIs[10] operating in SDR network in such a way that the architecture itself is suitable for the entire system to maintain the openness, object-orientedness, and software controllability.

In the verification and validation procedures regarding the safety-critical software of nuclear power plants for the attainment of the requisite license from the regulatory body, it is difficult to judge the safety and dependability of the development, implementation, and validation activities through a simple reading and review of the documentation. Therefore, these activities, especially safety assurance activities, require systematic evaluation techniques to determine that software faults are acceptable level. In this study, a safety case methodology is applied in an assessment of the level and depth of the results of the development and validation of a manufacturer in its targeting of the bistable processor of a digital reactor protection system, and the evaluation results are analyzed. This study confirms the possibility of an effective supplementation of the existing safety demonstration method through the application of the employed safety case methodology.

Ornaments is a province of the fashion. It usually express noble metals and jewel's adorn-ment as the symbol of status and riches for a long time. The ornament design of Jewels drawing project and a product by computer are increased development and as exertion as a realization of automation. Through the use of CAD software(Auto CAD R 13 & Jewel CAD) \circled1 A design development of the jewels in industrial society \circled2 A metals art & design on the dress and it's ornaments - Study about application of principle(liberal curve, arrangement of repeated form, gradual unity, rhythmical harmony) Although Auto CAD don't various expression of Jewels than a Jewel CAD, formative.scientific.funtional development of geometrical form is free. That is (to say), geometrical form is given much weigh in the general CAD, but Jewel CAD made concentrate software on the jewels design for the expression of liberal form. The CAD/CAM software for jewellery program is composed of main menu, icons, hotkeys. Changing form is derived from a definite point, curve elements of a drawing. \circled1 3-Dimensional \circled2 Easy and flexible \circled3 Bulit-in and self created library \circled4 From simple wire frame to full color images. As a CAD can practice all the creation activity effectively, from Design & Drafting Software to Rendering generally can present precise results. A point of view of the connection the scientist and art, this practicableness of CAD have a lot of possiblity of development. That will do much for the related fields of industry. Consequently, subjective intension of a creator & humanity with value plays role in practical application of the design.

Cloud vehicular networks are a promising paradigm to improve vehicular through distributing computation tasks between remote clouds and local vehicular terminals. Software-Defined Network(SDN) can bring advantages to Intelligent Transportation System(ITS) through its ability to provide flexibility and programmability through a logically centralized controlled cluster that has a full comprehension of view of the network. However, as the SDN paradigm is currently studied in vehicular ad hoc networks(VANETs), adapting it to work on cloud-based vehicular network requires some changes to address particular computation features such as task computation of applications of cloud-based vehicular networks. There has been initial work on briging SDN concepts to vehicular networks to reduce the latency by using the fog computing technology, but most of these studies do not directly tackle the issue of task computation. This paper proposes a Software-Defined Cloud-based vehicular Network called SDCVN framework. In this framework, we study the effectiveness of task computation of applications of cloud-based vehicular networks with vehicular cloud and roadside edge cloud. Considering the edge cloud service migration due to the vehicle mobility, we present an efficient roadside cloud based controller entity scheme where the tasks are adaptively computed through vehicular cloud mode or roadside computing predictive trajectory decision mode. Simulation results show that our proposal demonstrates a stable and low route setup time in case of installing the forwarding rules of the routing applications because the source node needs to contact the controller once to setup the route.
