Orthotropic decks composed of deck plate, ribs, cross beams and wearing surface are frequently used in industry to span long distances due to their light structures and load carrying capacities. As a result they are broadly preferred in industry and there are a lot of bridges of this type exist in the world. Nevertheless, some of them cannot sustain the anticipated service life and damages in form of cracks develop in steel components and wearing surface. Main reason to these damages is seen as the repetitive wheel loads, namely the fatigue loading. Solutions to this problem could be divided into two categories: qualitative and quantitative. Qualitative solutions may be new design methodologies or innovative materials, whereas quantitative solution should be arranging dimensions of deck structure in order to resist wheel loads till the end of service life. Wearing surface on deck plate plays a very important role to avoid or mitigate these damages, since it disperses the load coming on deck structure and increases the bending stiffness of deck plate by forming a composite structure together with it. In this study the effect of Elastic moduli, Poisson ratio and thickness of wearing surface on the stresses emerged in steel deck and wearing surface itself is investigated using a FE-model developed to analyze orthotropic steel bridges.

This paper analyses the theories and practices of the integrated management of records and archives in china which means that records and archives management departments should be interrelated each other with organic association and their records and archives be managed in an integrated manner. In 1930s chinese nationalist regime had conducted a campaign for reforming documents and archives management system to increase administrative efficiency called "The Connection of Documents and Archives Management Act(文書檔案連鎖法)". Although this campaign has not been continued to the present, It has been proved to be a quite successful attempt at that time in china and also regarded as an origin of the integrated management of records and archives in china. The practical types of the integrated management of records and archives as follows: first is to establish institutional documents/archives department in charge of managing records and archives in an integrative manner; second, to reform filing system, that is, to file on a case basis or abolish filing system and arrange records on an item level instead; third, to install software application for the integrated management of records and archives in order to make arranging operations convenient by increasing data processing efficiency. The chinese case shows us that the integrated management of records and archives could not be realized until records and archives departments make united efforts to build up a new national records and archives management system based on advanced and scientific principles.

리뷰 데이터 분석을 통해 추천을 하는 기존 시스템에서 사용자의 특성 혹은 상품 구매 취향와 같은 개인의 선호 세부 정보를 반영하지 않는 점을 보완하여 본 논문에서는 사용자가 상품을 검색하고 그 상품을 구매할 때 가장 중요하게 생각하는 기준을 선택하도록 하고, 이를 반영하여 분석함으로써 다양한 사용자에게 맞춤화된 추천 정보를 제공하는 시스템을 제안한다. 이는 사용자가 상품 구매 시 가장 큰 비중을 차지하는 기준을 토대로 가중치를 부여하여 감성분석을 수행하고 그 결과를 반영하여 상품 목록을 제공한다. 따라서, 상품 추천 정보에 사용자 개인의 선호도를 반영하였기 때문에 기존 추천 시스템을 통해 상품을 추천받는 것보다 효율적인 결과를 얻을 수 있을 것으로 사료된다.

처리과란 문서의 수발 및 사무처리를 주관하는 부서를 말하며 업무와 기록물생산의 시작점이다. 처리과에서는 기록물을 생산하는 것뿐만아니라 편철·정리·보존기간 책정·이관 등 기록물관리 업무의 대부분을 수행하고 있다. 이러한 처리과 기록물관리의 중요성에도 불구하고 처리과의 기록물관리 문제는 업무담당자들의 의지부족 등 개인적인 문제로 치부되곤 했다. 이 연구는 처리과 기록물관리의 중요성과 업무담당자가 생각하는 기록물관리를 설문조사를 통해 조사한 후, 기관 기록물관리 업무에서 개선해야 할 사항들을 도출하였다.

인터넷의 발달로 가격 경쟁력을 갖춘 전자상거래 서비스를 이용하는 소비자들이 매년 꾸준히 증가하고 있다. 반면, 가구 및 가전제품의 경우 크기 및 실내 인테리어와의 조화를 확인하지 못하는 문제점을 내재하고 있어 전자상거래를 통한 구매율은 증가하지 못하고 있는 추세이다. 따라서 본 논문에서는 증강현실 기술을 활용한 동작인식 영상처리를 통해 물품구매 전 가상으로 물품 배치를 하여 실내 인테리어와의 조화를 확인해 볼 수 있는 가구 및 가전제품 배치 시스템을 구현하였다.

The research purpose of this paper is to empirically examine the effects of technological readiness and innovation on logistics performance. To build up and maintain an important role in global supply chains, nowadays it is obvious that countries and logistics providers need to achieve competitive advantage in terms of digitalization. However, there is a lack of empirical studies about the impacts of information technologies and innovation potential on the logistics efficiency of countries. Hence, the study analyzes whether the corresponding pillars of the Global Competitiveness Index (GCI) matter for the Logistics Performance Index (LPI) and its dimensions. For determining the effects, the pooled regression approach is applied. The results show that technological readiness and innovation are positively and statistically significantly correlated with logistics performance: competence and quality of logistics services, efficiency of customs clearance processes, ability to track and trace consignments, frequency with which shipments reach consignee within scheduled or expected time, and ease of arranging competitively priced shipments. The findings of this study suggest that investments in innovations and technology progress improve countries' logistics efficiency, which is an important prerequisite for enabling Logistics 4.0 and thus, Industry 4.0 and the digital transformation of the economy and society.

Purpose: Even though arranging images of products is a common practice in the online retail context, relatively little attention has been paid to the distance effect among alternatives, that is, how distance among displayed products can impact consumers' responses. Drawing on contagion theory, the primary goal of the current study is to investigate how spatial distance between two products in a product display can influence consumers' perceived similarity. Research design, data and methodology: This study used a 2(spatial distance: close vs. far) experimental design and collected data from undergraduate students in Korea through an online survey using Qualtrics. ANOVA was conducted to test the proposed effect, in which the dependent variables are the perceived similarity of usage occasion/purpose (Study 1) and the indexed differences of perceived brand statuses between two products (Study 2). Results: The results of both experiments indicated that the displayed products were perceived to be more similar to one another when products were presented close together (vs. far). Conclusions: The results help to fill a research gap and provide a better understanding of the role of physical distance in diverse marketing communications. This is especially useful when designing online shopping websites to form perceptions of brand images.
