In this paper, we propose a novel applying method of Mobile IPv6 service into the UMTS to solve the mapping problems in the GGSN TFT packet filter. The mobility management tables or the GGSN should be maintained as the same as the MN and the CN. Our proposed scheme copes with the problem when the RO procedure is not normally performed by using Mobile IPv6 signaling packets in the GGSN and adding a function block in the UMTS. To show the performance of our proposed algorithm, we accomplish the simulations of measuring the delay time in the cases of success and failure of the RO procedure. Also, the amount of transmission is observed when the packet transmission is assured in the case of the successful RO procedure.

Nowadays, after beginning of 21 centuries, owing to simplify market, the world is in the era of an influx of new paradigm that requires infinite competition. The manufacturing industries of Korea are in need of casting off high cost and low efficiency structure. The forfeiture of competition is resulted from the lost of level in quality of product. Today, the achievement of competitive product quality is coming from the following factors, that is., quality control, quality of service, marketing, human resources, finance, etc., together with process management. While Six Sigma, a newly introduced method to achieve process qualify outcome by sector of enterprise, is now being enjoyed a high reputation as a key device for competition by superiority enterprises in the United States, it has not been introduced sufficiently in the domestic enterprises yet. In our research, we, first of all, organized systematically the materials being released up to now. Furthermore, we looked over case studies of the American enterprises that apply Six Sigma strategy very successfully. Finally, we discussed the situation of domestic enterprises which are about to importing Six Sigma strategy as well as main causation of success by adopting it. While the enterprises approach Six Sigma strategy not in the way of on time and short term but in the way of long term, consistent renovation and persistent innovation we can assure that they will produce the highest quality and globally competitive products which are second to none.

A total of nine oral health educators for 17 persons with developmental disabilities conducted oral health education once a week for four weeks. The oral health educators provided oral health knowledge education and individual toothbrushing teachings. The developmentally disabled people in their 20s and 30s conducted oral health education without a guardian. Ten people who completed all the four pieces of training had no significant improvement in the toothbrushing method and the recommended number of toothbrushing sessions a day, as well as a lack of growth in oral health knowledge. However, 58.8% of the individuals expressed satisfaction with the oral health education program, whereas, 52.9% expressed the desire for a re-education. Although the ratio of teachers to students was 1:2, and the oral health education conducted four times, it was insufficient to promote a successful oral health behavior or knowledge for people with developmental disabilities. Therefore, as a suggestion, oral health education for people with developmental disabilities ought to proceed with their guardians to promote the success of the training.

Focusing on the issue that the conventional Kernel Correlation Filter (KCF) algorithm has poor performance in handling scale change and obscured objects, this paper proposes an anti-occlusion and scale adaptive tracking algorithm in the basis of KCF. The average Peak-to Correlation Energy and the peak value of correlation filtering response are used as the confidence indexes to determine whether the target is obscured. In the case of non-occlusion, we modify the searching scheme of the KCF. Instead of searching for a target with a fixed sample size, we search for the target area with multiple scales and then resize it into the sample size to compare with the learnt model. The scale factor with the maximum filter response is the best target scaling and is updated as the optimal scale for the following tracking. Once occlusion is detected, the model updating and scale updating are stopped. Experiments have been conducted on the OTB benchmark video sequences for compassion with other state-of-the-art tracking methods. The results demonstrate the proposed method can effectively improve the tracking success rate and the accuracy in the cases of scale change and occlusion, and meanwhile ensure a real-time performance.

Productivity of public organizations was far older due to issue more difficult to measure than private organizations. Unlike the private sector, the public sector is a diverse and sometimes conflicting objectives (efficiency, effectiveness, equity, democracy, etc.) exist, it is difficult to measure productivity in a single index. Many departments of government is intricately interrelated and sometimes produced by the joint efforts, it is difficult to allocate performance, incentives and accountability to among departments. And there is the difficulty of collecting data on the productivity indicators of public organizations. Despite these difficulties, we developed a productivity index system and measuring method to systematically introduce the concept of productivity in the local administration. In this paper, the productivity and the productivity index measurement practices of local governments conducted annually from 2011 on was deep into research. First, the report found examples of the governments of the developed countries, productivity measurement, then the way MOPAS(Ministry of Public Administration and Security) measure productivity index of local governments, success factors, the implications were in-depth analysis. Finally, in order to enhance productivity and competitiveness municipalities studied ways to take advantage of the productivity index.

The temperature control of in-place concrete is the most important factor for an early age of curing concrete. Heat stress of mass concrete caused by the heat of hydration can induce the crack of concrete, and a frost damage from cold weather casting concrete results defect on compressive strength and degradation of durability. Therefore, success and failure of concrete work is dependant on the measurement and control of concrete temperature. In addition, the compressive strength assessment of in-place concrete obtained from the maturity calculated from the history of temperature make a reduction of construction cycle time, possible. For that purpose, wireless temperature measuring system was developed to control temperature and assess strength of concrete. And, it was possible to monitor the temperature of concrete over 1km apart from site office and to take a proper measure; mesh-type network was developed for wireless sensor. Furthermore, curing control system that contains the program capable to calculate the maturity of concrete from the history of temperature and to assess the compressive strength of concrete was established. In this study, organization and practical method of developed curing control system are presented; base on in-place application case.

VANET (vehicular ad hoc network) refers to the case networks designed for vehicles. Such networks are established among the vehicles which are equipped with communication tools. Within these networks, vehicles are regarded as the network nodes. On time and on schedule transmission of data is of high significance for these networks. In order to accomplish the objective of on-time data transmission, specific electronic equipment is embedded in each vehicle which maintains ad hoc communications among the passengers. Information about traffic, road signs and on-line observation of traffic status can be transmitted via these networks; such data makes it possible for the driver to select the best route to reach his destination. If there are not any infrastructures, two broadcasting approaches can be considered: overflowing and rebroadcasting. The overflowing approach leads to heavy traffic. Hence, the challenge we face is to avoid the broadcasting flood. In this paper, an approach for the management of the broadcasting flood is proposed based on fuzzy theory. The proposed method is assumed to have better performance and efficiency than any other approaches in terms of crash rate, the rate of message success and delay

The Domestic Construction Industry is in the process of changing from a one-sided production method centered on the contractor to a production method in which the order and the contractor can collaborate. Depending on the delivery method, the bid/success method, the contract method, and the degree of business involvement of the order may also vary. In this thesis, in order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bid process analysis, contract fulfillment and management analysis, post management analysis, and related laws and regulations for legalization In order to suggest a plan for the efficient operation of the system, a system and case analysis of domestic and international construction responsibility type construction project management was conducted. 'Construction Responsible Construction Project Management' defined in the Framework Act on the Construction Industry is divided into the main contract transfer contract, which is a service contract performing pre-con work, and the main contract, which is construction project management and construction contract. Therefore 'Construction Management at Risk' should be regarded as one of the ordering methods rather than a successful bid system, as in the case of overseas, and legalization as a bidding system equivalent to design/construction batch bid and technology proposal is necessary for introduction. In order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bidding process analysis, contract fulfillment and management analysis, and follow-up management analysis are conducted. A method for efficient operation was suggested so that it can be applied in the domestic market while maintaining the original merits of this system.
