In order to comprise a basic closed-loop control system for a field robot it is necessary to detect the piston rod stroke of a hydraulic cylinder. There are mary conventional type sensors which can detect the displacement of cylinders. However, they cannot reveal the original performance normally or the cannot be applied at all where the operating circumstance of cylinders is beyond specifications of sensors. In this paper, an exclusive method for detecting the piston rod stroke is suggested, which adopts a remote detecting technique using optical fiber sensors. Several experiments using the prototype are executed for verifying the effectiveness of the suggested method and the possibility of the accurate detection of stroke.

The distinctive design of apparel product is the crucial factor that provides the powerful competitive advantage and customer satisfaction. However, knock-offs or copycats easily copy the design of apparel product and its problem tends to be assented in real world. Design right is one of intellectual property rights that would be produced by intellectual activity and the appropriate means to establish the exclusive rights to the design should be established. Legal protection to the design right is the system that can prelude copycats from eroding an exclusive position in the market place. The present study was to analyze the trend of registration of design rights in apparel products and to point out problems of current protection law to design.

This paper represents the Input/Output (I/O) serial communication methods between overground and overhead controllers using a programmable logic controller (PLC). In general, the systems composed by overground and overhead controllers use exclusive serial communication units. This, however, has a demerit such as a high cost as well as some restrictions of the system itself. Thus, this paper suggests methods by I/O cards for data communication between overground and overhead controllers. In this system, there is no special card and it therefore has a lower cost and is more flexible than the exclusive serial communication unit.

It is impossible to obtain the growth of library and the information culture of high quality without the desirable policies. Korean libraries have been developed steadily through the efforts of the authorities concerned. libraries, the library and information science, and the library business area. For the growth of Korean library culture and knowledge information society in the 21st century, I suggest that we should set up new library policies: (1) establishment and effective administration of advisory organizations of library, (2) revision of "the library and reading promotion law" and other related laws, (3) establishment of an exclusive bureau for administration of library, and (4) continuous development of informatized library.d library.

The biggest obstacle in utilizing Telerobotics is that an exclusive line is necessary to connect the distant place and manipulator for the purpose of remote control. Moreover, installment of an exclusive line Is limited to relatively short distance, as the installment entails more difficulties with longer distance and increasing installment cost. The purpose of this paper is to suggest a methodology of factory automation by using Lab VIEW to control and monitor actuators, which are the basis of controlling manipulators, form distant places.

In this paper, the present state of the experiments in the mechanical engineering education is analyzed and the improving methods of the experimental education are presented. Data at twelve universities are collected. In spite of the general understanding of the importance of the experiments, the portion of the experiments is less than 10%. It shows the need to increase the experiments. Experiments for basic mechanics are fairly well performed, but experiments for applied subjects would be strengthened. Several improving methods such as systematic support for experiments, use of the exclusive assistants for experiments, and so on are discussed.

In this paper we tried to overcome the limit of contents which occur when we implement the augmented reality technology adapted application on commercialized mobile system. First of all, we checked the requirement analysis of exclusive mobile system to support augmented reality. And then we designed and realized the mobile system based on this facts. Also we embodied augmented reality application based on NyARToolkit which assists augmented reality techniques. Finally the implemented contents operated properly in our exclusive mobile system. Consequently we confirmed the suitability and validity of our system through above test.

The aim of this study is to analyze the distribution structure of exclusive digital muti-media broadcasting's contents. This study takes into distribution wether exclusive contents create an additional window being serviced to other media. And it investigates how the contents work in window through analysis of programming table and interview with programming editors of each DMB service company. The window effect is a same notion to the one source multi use. In the film industry, window means a movie distribution that a film can be on one after the other starting the cinema, DVD, local cable channel, and terrestrial television. The key point of this paper is how to new media, DMB, creates its additional window and changes the existing window structure.

It's prohibited to take sand from southeastern EEZ(Exclusive Economic Zone) from January 2017 in korea. So, the supply of sea sand has been decreased and costs of sea sand are rising as a result in the southeast region. This paper deal with appropriateness of the taking sea sand, circumstance and fisheries damages by extraction of EEZ sand and proposed control measures for ensuring quality of sea sand and consider fishermen support plan for ensuring a stable supply of sand in southeast region of korea.

In this paper, we present MI-MESI write-invalidate snooping cache coherence protocol which addresses several significant drawbacks of MESI and MI-MESI write -invalidate snooping cache coherence protocols under the split transaction bus based multiprocessor environment. In this protocol, each cache block maintains one of six cache states which represent Modified-shared, Invalid-by-other, Modified, Exclusive, Shared and Invalid states. By using these cache states, our protocol reduces both the access contention and unnecessary updates for the memory modules significantly, and thus providing the fast memory access time.
