This study proposes a deep learning-based evolutionary recommendation model for heterogeneous big data integration, for which collaborative filtering and a neural-network algorithm are employed. The proposed model is used to apply an individual's importance or sensory level to formulate a recommendation using the decision-making feedback. The evolutionary recommendation model is based on the Deep Neural Network (DNN), which is useful for analyzing and evaluating the feedback data among various neural-network algorithms, and the DNN is combined with collaborative filtering. The designed model is used to extract health information from data collected by the Korea National Health and Nutrition Examination Survey, and the collaborative filtering-based recommendation model was compared with the deep learning-based evolutionary recommendation model to evaluate its performance. The RMSE is used to evaluate the performance of the proposed model. According to the comparative analysis, the accuracy of the deep learning-based evolutionary recommendation model is superior to that of the collaborative filtering-based recommendation model.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

Since software and hardware integration has became a strategic tool for companies to innovate their products, an information system that can comprehensively manage software and hardware integrated product development is critical for the current product development. This paper proposed a product data model that can support modules of related software and hardware parts in Product Data Management(PDM) integrated with Software Configuration Management(SCM). The model allows engineers to define software and hardware product structure independently, and support the integration module that can summon related software and hardware parts to build a comprehensive module for collaboration. Through the integration module, engineers can identify and examine the effectiveness of their design alternatives to other related parts form different disciplines. The product data model was implemented as a prototype PDM system and tested with an example robotics product.

Manufacturers have recently faced such problems like limitation of product differentiation, product commoditization and increased service request level from customers, Some manufacturers have responded the problems by introducing new business model, 'product and service integrated offering', which integrate product and its services as a bundled package, This article introduces innovative 7 cases of 'product and service integrated offering', and provides case analyses : types, methods, purposes, and risks of integration, The result of analysis, 4 strategic directions for product and service integration offering, could help manufacturers to adopt and build their model successfully, Further research topics are field survey with meaningful sample size including Business-to-Consumer and finding new causal relationships among variables like characteristics of industry, product, Integration, interaction between provider and customer, A development of design methodology on how to plan and develope a sound product service integration is the second next step for the research.

This work presents a proposal for employing reduced numerical integration in the formulation of the 4-node quadrilateral solid finite element. The use of these low-order integration rules leads to numerical instabilities such as those producing the hourglass effect. The proposed procedure allows evaluating a given constitutive model only in one integration point, achieving an attractive computational cost reduction and, also, successfully controls the hourglass effect. A validation of the proposal is included and discussed throughout the paper. To show the efficiency of the proposal, several application examples of masonry structures are studied and discussed. To represent the non-linear mechanical behaviour of masonry a plastic-damage model is implemented within the application of this sub-integration scheme. Also, in order to have a full and computationally efficient strategy to determine the behaviour of masonry structures, involving its evolution to collapse, a homogenization technique with a macro-modeling approach is used. The methodology discussed throughout this paper demonstrates a substantial computational cost reduction and an improved approximation of the non-linear problem evidenced by a reduction of up to 85% of the computational time for some cases.

In this paper we propose the approach for big data integration so as to analyze, visualize and predict the future of the trend of the market, and that is to get the integration data model using the R language which is the future of the statistics and the Hadoop which is a parallel processing for the data. As four approaching methods using R and Hadoop, ff package in R, R and Streaming as Hadoop utility, and Rhipe and RHadoop as R and Hadoop interface packages are used, and the strength and weakness of four methods are described and analyzed, so Rhipe and RHadoop are proposed as a complete set of data integration model. The integration of R, which is popular for processing statistical algorithm and Hadoop contains Distributed File System and resource management platform and can implement the MapReduce programming model gives us a new environment where in R code can be written and deployed in Hadoop without any data movement. This model allows us to predictive analysis with high performance and deep understand over the big data.

Currently, it is not easy for most domestic public libraries to collect and provide reliable health information services on their own. Health information is distributed or professional, making it inconvenient for users to use. Based on the implications derived from the case study, the Library Health Information Integration Service Model was proposed as a specialized information service. The model consists of a composition shared by librarians, health and medical experts, and users, focusing on library websites that provide integrated health information integration services, and has the following features. First, it provides health and medical information on a specialized subject. Second, it provides integrated health and medical information services provided in various ways. Third, librarians and health and medical experts work together to provide information services. Fourth, users can freely use health information integration services online and offline. The model presented in this study means that libraries can play a leading role in health information integration services to increase the utilization rate of public libraries and further contribute to librarians serving as experts in health information services.

항공전자시스템을 개발하는 과정에서 개별 구성품의 기능 및 연동 검증을 위한 통합시험환경(SIL; system integration laboratory)을 구성한다. 이러한 SIL의 구성품 개별 검증 및 시스템 통합 시 각 탑재장비의 기능 및 연동을 모의하는 SIL 모델을 개발하여 이용한다. SIL 모델은 실 장비와 연동되기 전 연동통제문서(ICD; interface control document)에 정의된 모든 데이터에 대해 선 검증되어야하며 ICD 변경 혹은 기능 변경 발생 시에도 재 검증되어야한다. 하지만 SIL모델의 검증의 수동 수행 시 개별 SIL모델의 검증에도 상당한 시간이 소요된다. 이러한 시간상의 문제로 ICD 변경이나 일부 기능 변경 시에는 SIL 모델의 영향성을 판단하여 선택적 회귀시험이 이루어지곤 한다. 본 논문에서는 이러한 SIL 모델의 검증에 소요되는 시간을 최소화하여 회귀시험 수행 시 모든 시험항목의 검증이 가능하도록 SIL 모델 검증 자동화 방안을 설계하고 설계에 따른 SIL 모델 검증 자동화도구를 개발하여 SIL 모델 검증자동화 설계의 유용성을 검증하였다.
