The computer was only used to calculate and solve the mathematical problems, to send the simple data, and to exchange the text based informations in the early 1990's. But nowadays, computer technology give us the chance to exchange digital goods and services, etc. And more, computer and computer based systems can be applied everywhere, for example, it can be used at office, at home, and at school. Most of all, one of the remarkable changes is the development of mobile industry, which can be applied anywhere and anytime. So, this study focused on the current situation and promotion plans of the mobile industry. Mobile is based on the IT, IT and mobile technology are the foundation stone of ubiquitous computing environments. Accordingly, this thesis analysis the meaning of ubiquitous, the meaning and roll of mobile industry. With the analysis of this, the conclusion is that to develop and success the new business model at home and overseas, the cooperation of government section and industry section is the most import thing to make it out.

The computer industry has come to the generation of personal computer. The organization of the existing industry has the distinct boundary among companies in vertically integrated companies, produce whole assembled system, and compete in the part of hardware, operating system, and its related software based on theirselves design. Then according to keep the distinct monopolized architecture of industry, the enterprises only centralized on developing the monopolistic market and sharing the static market rather than competition and compatibility with other system. The horizontal distribution in small part industry is occurring, by the times of personal computer, and the companies of personal computer have coming into free competition with parts standardization and the open architecture of system. This paper suggests a reasonable model of industry under horizontal structure with analyzing the above phenomenon.

In these day, our life has been developed with the computer. Printing Industry was introduced the information industry as computer, internet, etc. These are now in daily use and covers the entire work flow - from the planing of the product and the production at domestic printing industry. Then, I suggest the correspondence of changing printing work flow, understanding of digital printing technique, rearing of a special line of business, adjustment in the environment changing of printing technique etc. for the purpose of development of domestic printing industry.

The easy scalability and low cost of range-free localization algorithms have led to their wide attention and application in node localization of wireless sensor networks. However, the existing range-free localization algorithms still have problems, such as large cumulative errors and poor localization performance. To solve these problems, an incremental strategy-based residual regression network is proposed for node localization in wireless sensor networks. The algorithm predicts the coordinates of the nodes to be solved by building a deep learning model and fine-tunes the prediction results by regression based on the intersection of the communication range between the predicted and real coordinates and the loss function, which improves the localization performance of the algorithm. Moreover, a correction scheme is proposed to correct the augmented data in the incremental strategy, which reduces the cumulative error generated during the algorithm localization. The analysis through simulation experiments demonstrates that our proposed algorithm has strong robustness and has obvious advantages in localization performance compared with other algorithms.

A computer program called LAMPRO has been developed for use by the Australian meat industry to assist with the pricing of lamb carcasses. Based on a series of prediction equations and accounting for the cost structure of a meat processor the program allows the real value of a carcass to be established. The concept has also been extended to cater for mutton carcasses destined for either domestic or export markets incorporated in a program called MUTONPRO.

In industry areas, a lot of factories and process plants need network for processing data acquired from field and for communicating between sensors or actuators or field controllers. Most of the industry networks are based on wired solutions. But, recently, a lot of factories and process plants are moving into wireless solutions since they have some advantages compared with wired one. In this paper we first review the characteristics of wired and wireless network technologies and introduce the new technique called wireless sensor network (WSN). And then we describe the wireless sensor node system designed by us for WSN which has the ability of small size, flexibility and low-power consumption and embedded into the Bar-code scanner to communicate each other. Finally, we conclude this paper by showing that wireless industry network can be constructed with wireless sensor network without large change of traditional wired topologies through experiment using wireless sensor nodes.

Participatory sensing applications rely on recruiting appropriate participants to share their surrounding conditions with others, and have been widely used in many areas like environmental monitoring, health care, and traffic congestion monitoring, etc. In such applications, how to ensure the privacy of a participant is important, since incentive mechanisms are used to maintain their enthusiasm for sustainable participation by offering certain amount of reward. In this paper, we propose a pseudonym-based privacy protection scheme, that takes both privacy protection and user incentives into consideration. The proposed scheme uses the pseudonym mechanism and one-way hash function to achieve user incentives, while protecting their identity. We also show extensive analysis of the proposed scheme to demonstrate that it can meet the security and performance the requirement of a participatory sensing application.

Road damage detection is important for road maintenance. With the development of deep learning, more and more road damage detection methods have been proposed, such as Fast R-CNN, Faster R-CNN, Mask R-CNN and RetinaNet. However, because shallow and deep layers cannot be extracted at the same time, the existing methods do not perform well in detecting objects with fewer samples. In addition, these methods cannot obtain a highly accurate detecting bounding box. This paper presents a Multi-level Feature Pyramids method based on M2det. Because the feature layer has multi-scale and multi-level architecture, the feature layer containing more information and obvious features can be extracted. Moreover, an attention mechanism is used to improve the accuracy of local boundary boxes in the dataset. Experimental results show that the proposed method is better than the current state-of-the-art methods.

Radio Frequency Identification (RFID) skill is becoming a technology that might deliver a response to manual glitches. The use of tags, receiver and wireless surfs to join with each other would mean that RFID in combination with the EPC would speech these pain opinions and offer many welfares in different sectors such as production, distribution, trade, logistics, and security. Potential benefits include increased visibility rising supply chain, enlarged proficiency and cost savings through improved data harmonization, better responsiveness to actual prominence change. Trendy the case of the textile or industrial applications, recent systems used by the industry to control the supply chain in addition strength discernibility are being studied, besides improvements in the overall perceptibility of assets are anticipated through labels, readers, drivers, POEs, etc. this model will be developed with new situations and a lively construction industry. It will be focused on Cost, Hardware compatibility, security and maintenance issues.

Korea remains one of the few countries in the world that has not participated in any formal regionalism except its first FTA with chile which was just recently concluded. The lack or regionalism in Northeast Asia reflects post-war national policies that favored international export markets as an engine of economic growth. Based on a survey of 50 firms in Korea, this paper examines the relationship between regionalism and multilateralism in terms of computer industry. The results show that the industry favors international rather than regional markets for its continued export growth. According to the results, accelerated trade liberalization measures through the mutilateralism of the WTO dilute the demand for and negative impacts from regionalism. Overall, the results suggest that the Korean computer industry supports a trading system with a strong multilateral commitment based on non-discrimination.
