This paper deals with the domestic status of rail gap and criteria of the maximum allowable rail gap for the broken rail. Parameteric studies about the maximum allowable rail gap were accomplished by the zimmermann model. The dynamic behavior of broken rail not to be explained by the existing theory was looked into. When a train is travelling along rail gap for the broken rail, dynamic behaviors of rail system and train are abruptly changed. And the opinion about a permission criteria of the rail gab was presented.

The Bi-directional Wireless Capsule endoscope con sists of CMOS Image sensor, FPGA, LED, Battery, DC to DC Converter, Transmitter, Receiver and Antennas. The RF transmitter at 1.2GHz range is designed and fabricated with 10 mm(diameter)x1.6 mm(thickness) dimension considering the maximum permission exposure(MPE), system size, power consumption, linearity and modulation method. The fabricated RF receiver at 400MHz range can demodulate the external signals so as to control the behavior of CMOS image sensor. four LEDs and Transmitter.

This study is to prepare a reasonable basis for the improvement of the electrical safety management regulation. The standards in domestic and foreign countries for the application of new and renewable energy facilities and other devices are analyzed. Other regulations excluding the electrical safety fields and wide surveys are also carried out. Consequently, it is asked that the classification between normal and self electrical facilities should be clear and deregulation for small businesses has to be followed. This study is showed that standards investigates of receiving equipment below 600V above 75kW, eletrical safety manager employment of manufacturing industry and Mid-night electric power. And, it is showed that consignment permission and Consignment inspection periodic relaxation about wind development equipment below 1,000kW, consignment of Technical Development equipment for new and renewable energy below 250kW.

The purpose of this paper is to make a sentence systemic within the category of structural grammar for the modality in which a speaker expresses his attitude. It is the priority of a language to communicate meaning. By eliminating the theoretical description of traditional grammar, this paper also aims to illustrate the concepts of nine modal verbs through a systemic network. The concept of modality includes both the epistemic and the deontic characteristics of modality. Epistemic modality is associated with either knowledge or belief on the part of a speaker who gives his own judgments about the state of affairs, events, or actions. However, deontic modality is related to either the possibility or the necessity of acts that a speaker performs to give permission or fulfill an obligation. In conclusion, all the subsystems are described within the framework of the systemic network, with the intention of including all the potential options of the semantic functions available in a situation.

International trade conflict has been increased since WTO has appeared. Like this, the cause that the number of international trade conflict has been increased is by means of enlargement of agreements range. But some new facts have been added. They are Anti-dumping, subsidy, Countervailing duty, Safeguard, the norm of intellectual property right, the procedure of permitting importing products, Technical Barriers, agricultural products, and the area of textile. Since Japanese government has decided to give lavor import quarters to China without permission of Korea, Korean government formally presented the system of lavor import quarter to WTO DSB due to WTO agreement disobedience of Japan. Accordingly, this paper has the following purpose; to analyze situation on fiber dispute of Japan. Some methods about trade barrier against Japan need to be solved from another viewpoint owing to lavor IQ dispute.

We are now using separate ID Database, Permission System, OS and Standard Data Format in PC, Cell phone, IPTV service and these are not good in many kind of usage, data sharing, contents servicing and supervising efficiency To merge these multiple services into one system we need to make a single ID systems for all and this paper will gide you to the new ID system that was much better than the old one. This new type of ID system is made with 3D Data and this will give fantastic visual effect & rich information data to the ID users in 3D way which is much better than 2D image & Text information technology.

This study is concerned with a few models for optimal requirement level of CSP by improving and adjusting the existing models to determine CSP items and quantity as follows. First, by building a model with a objective function of the operating level and constrains of budget, quantity and items of CSP are simultaneously determined. Second, we removed some steps to improve initial solution by using a constraint of usable budget level. Third, we demonstrated a model to be applied with real operating situation by combining two models of Lee(1994) and above. Lastly, by assuming a failure probability distribution is a binomial distribution, the better solution can be obtained. Some facts with necessity of policy improvement were raised as follows: (1) necessity of improvement of the CSP acquisition system, (2) in case of the same kind, permission of diversion in order to execute budget effectively, (3) getting accurate failure rate.

There is a rental housing policy in Korea to support low income citizen. However, the living condition of tenants through this rental program is not work for improving, unlike the initial purpose of providing rental housings. Rental housings, which were planned to improve the residential welfare and enhance self-reliance ability of low income groups and the elderly. It's not effective any more in terms of policy purpose. To solve this problem, plans are needed to support for the construction by Farm-Housing(FH) so that the residents of can support their self-reliance by promoting creating jobs and cooperation. This paper analyze and propose some solution in terms of legal system, financing and streamlining of planing process and permission to support FH program. The paper focus purpose to help identify a new area through such proposals and retain a power of leading technology by bridging the gap between the realistic aspect and ideal aspect.

Flicker, which is also known as voltage fluctuation, is an electromagnetic phenomenon generated by large scale nonlinear loads, such as arc furnaces and welding machines. Since a severe and continuous flicker can cause to some damages to electrically sensitive loads as well as human's visual irritations, it needs to be appropriately managed by being accurately measured, quantified and assessed. In Korea, an equivalent 10-Hz flicker index, shortly ${\Delta}V10$, is used to determine the permission limit of flicker. This paper presents an efficient calculation of the flicker index by using a half-cycle sliding window and a recursive method, showing a concrete calculating procedure of ${\Delta}V10$ from the viewpoint of signal processing.
