Smart IoT over high speed network and high performance smart devices explodes the ubiquitous services and applications. Nearest Neighbor(NN) query is one of the important type of queries that have to be supported for ubiquitous information services. In order to process efficiently NN queries in the wireless broadcast environment, it is important that the clients determine quickly the search space and filter out NN from the candidates containing the search space. In this paper, we propose a hybrid index of Voronoi and grid partition to provide quick search space decision and rapid filtering out NN from the candidates. Grid partition plays the role of helping quick search space decision and Voronoi partition providing the rapid filtering. We show the effectiveness of the proposed index by comparing the existing indexing schemes in the access time and tuning time. The evaluation shows the proposed index scheme makes the two performance parameters improved than the existing schemes.

본 연구는 국내 섬유의류산업의 공급사슬관리 시스템인 QR(Quick Response) 시스템 구현에 웹서비스 기반의 ASP(WS-ASP) 모델을 제시한다. 국내 섬유의류산업은 대부분 중소기업으로 구성되어 있어서 전문 IT인력을 확보하기 어렵고 대규모 IT 투자여력도 없는 형편이다. ASP 모델은 소프트웨어 온 디맨드 서비스를 저렴한 사용 수수료로 제공받을 수 있다는 장점 이 있으나, ASP 벤더에 대한 의존도가 높아 벤더 위험이 크다는 단점이 있다. 본 연구는 WS-ASP모델을 통해 소프트웨어 온 디맨드 서비스를 여러 특화된 WS-ASP벤더에 분산시켜 벤더 위험을 감소시킴으로써 ASP모델의 단점을 보완하여 QR 시스템에 적절함을 제시하였다.

Quick Response based Mass-Customization can be produced and distributed customized goods and services on mass basis in apparel e-business. Because consumers can: t touch and feel the apparel products in e-business, they tend to have the negative buying behavior. The purpose of this study is to investigate the differences of consumer's texture sensibility of apparel products based on marketing channels (on-line/off-line). Two types of questionnaires for on-line and of f-line were used to assess consumer sensibility on apparel fabric. The 8 swatches were selected in regard to the previous literatures. 205 questionnaires for each type (on-line/off-line) were distributed. Statistical devices were t-test, mean and standard deviation with SPSS10.0. The result of this study was showed that there were partially significant differences on consumers' texture sensibility on apparel products between on-line and off-line. Under on-line environment, consumers perceived corduroy as warm, strong, and sandy. taffeta as warm, sandy, and glossy, denim as sandy, and warm, organza as sandy, and thin, satin as sandy, dense, and modern, chiffon as sandy, and flat, velvet as warm, and soft, single jersey as warm, soft, and comfortable. Therefore, apparel firms cooperating based Mass-Customization in e-business have to pay attention to the differences on consumers’ texture sensibility of on-line apparel products from those of off-line.

Existing web applications and services have historically been implemented using JavaScript. However, new technologies such as artificial intelligence, the Internet of Things, and Big Data are being developed as part of the Fourth Industrial Revolution. With the definition of the HTML5 web standard, services (such as the technologies mentioned above) that were previously not available through the Web become available. These services, however, need to have the same performance as native applications, and implementing these services will require new technologies. Therefore, additional tools that can work on the Web with native performance are needed. In this paper, a system for branching processing was established using JavaScript and WebAssembly, a language that can operate on the Web. This system performs user requests in advance, and requests are branched in a language that produces faster results. Therefore, a service capable of quick response times can be implemented.

The interest and importance of the convergence services for healthcare expand more and more as the average life expectancy increases. Convergence of ICT and healthcare technology unfold efficient and quick health services. Recently, healthcare services provide to clients with apps over web. On-demand wireless data broadcast supports any number of clients to access their desired data items dynamically by responding the needs for data items from the clients. In this paper, we propose an on-demand system to broadcast FHIR bundles for efficient healthcare services. We use time-parameterized replacing policy for renewing the bundle items on the wireless broadcast channel. The policy lets the on-demand broadcasting dynamic by controlling the time duration for the bundles to reside over the wireless channel. With simulation studies using an implemented testbed, we evaluate the performances of the proposed system in access time and tuning time. For evaluation, we compare the time-parameterized replacing policy of the proposed system with regular-number replacing policy. The proposed time-parameterized replacing policy shows shorter access time than the regular-number replacing policy because the policy responds more actively and dynamically to the change of the needs of the clients for FHIR bundles.

This paper proposes a mathematical modeling-based approach for assessing disaster effects and selecting suitable mitigation alternatives to provide humanitarian relief (HR) supplies, shelter, rescue services, and long-term services after a disaster event. Mitigation steps, such as arrangement of shelter and providing HR items (food, water, medicine, etc.) are the immediate requirements after a disaster. Since governments and non-governmental organizations (NGOs) providing humanitarian aid need to know the requirements of relief supplies and resources for collecting relief supplies, organizing and initiating mitigation steps, a quick assessment of the requirements is the precondition for effective disaster management. Based on satellite images from weather forecasting channels, an area/dimension of the disaster-affected zones and the extent of the overall damage may often be obtained. The proposed approach then estimates the requirements for HR supplies, supporting resources, and rescue services using the census and other government data. It then determines reliable transportation routes, optimum collection and distribution centers, alternatives for resource support, rescue services, and long-term help needed for the disaster-affected zones. A numerical example illustrates the applicability of the model in disaster mitigation planning.
