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.

다양한 이동 통신을 수용 할 수용하기 위해서 SDR system의 하드웨어와 소프트웨어는 개방성, 분산성, 객체 지향성, 소프트웨어 제어성을 제공하는 구조이어야 한다. 이러한 조건을 만족하는 SDR 시스템에 사용될 SDR시스템의 소프트웨어는 단일 하드웨어 플렛폼에서 독립적으로 동작이 가능한 개방성을 확보하는 것이다. 이 방법은 모듈화를 지향하며, 재사용성을 증대시키고, 개발 시에도 많은 유연성을 확보 할 수 있을 뿐만 아니라 개발 시간을 단축시켜 주고 시스템을 재구성하여 운용 할 수 있도록 해 준다. 본 논문은 SDR기반 스마트안테나 기지국 시스템에서 SDR Network이 추구하는 개방형, 객체지향성 및 제어성 등을 확보 할 수 있도록 하고 SDR Network와 유연하게 연동 할 수 있도록 제안된 개방형 기지국 시스템과 스마트 안테나 기지국 API(Application Program Interface)를 이용하여 기지국 시스템을 구현하였다.

원자력발전소 안전-필수 소프트웨어를 개발하고 검증 및 확인을 수행하여 규제기관으로부터 인허가를 받기 위하여 단순하게 문서를 읽고 검토해서는 개발, 구현 및 검증활동에 대한 신뢰성과 안전성 확보에 대하여 정확하게 판단하기가 쉽지 않다. 따라서 이러한 활동, 특히 안전보증 활동이 소프트웨어 결함이 허용가능한 수준인지 판단하기 위한 체계적인 평가기술이 필요하다. 본 연구에서는 원전 디지털 원자로보호계통의 비교논리 프로세서와 동시논리 프로세서를 대상으로 제작자가 수행한 개발 및 검증 결과물의 수준과 깊이를 평가하기 위해 안전진술(Safety case) 방법론을 적용하고 그 결과를 분석한다. 안전진술 방법론 적용으로 기존의 안전입증 방법을 효과적으로 보완할 수 있음을 확인하였다.

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.
