  • The purpose of this study was to draw social constructive implications for the child protect system(CPS) in Korea. As the value of social constructivism for child protect system, the participation and the negotiation were identified through theoretical research. And this paper examined how the participation and the negotiation were done in other government's child protect policies. In addition, the focus group members were interviewed. 11 child protect practitioners and researchers were interviewed about the problems of child protect system, law and policies, and they discussed how the participation and the negotiation were done in Korean child protect system. The result of the discussion were as follows. The democratic relationship must be reconstructed through the participation and negotiation in CPS, Korea lacks of legal basis to force the abusers to participation. And in our country, negotiation parties for children cannot be recognized. Finally, the amendment of the law and regulations concerned with the child protect system were proposed based on the FGI's discussions.

  • In the commercial transaction sellers use various sales strategies to increase profits, and this kind of sales strategies often causes damage to customers, it, moreover, is true that these examples happen in the electronic commercial market much more than in traditional one because of the characteristics if the electronic commerce. That's why people transact one another without face-to-face meeting in the electronic commerce market, so people one likely to fall for a trick to cheat and deceive. It's no doubt that the frequency of crime is higher than in face-to-face market. For that reason Cooling Off System, Consumer Compensation Insurance, Mutual Aid Association and Billing Payment Deposit System are in force the law related electronic commerce to protect customers' rights. In this paper it will be discussed about the periods of Cooling Off System and a received commodity notice of the Billing Payment Deposit System. Regarding these periods seven days for Cooling Off period and three days for a received commodity notice period are stipulated under the law of related electronic commerce to protect customers' rights, But each period has to be differentiated depending on each goods for this period to be reasonable and proper. Therefore in this study it will be focused on these facts and each period will be classified by the goods' purpose of purchase and quality.

  • The safe operation of electro railways is greatly dependant on its protective systems. The system so-called Fault Protection Wire(FW) is now widely adapted to protect in AT feeding systems. It is connected between the feeder and trolley circuit to return the fault current to autotransfonmers at substation. This paper computed the distribution of fault currents at FW in the system and also evaluated the safety from electric shock when ground fault or flashover occur in the feeding system. The results show FW is useful to protect power supply network from fault in electric railways

  • In electrical machinery and apparatus, the most important problem is protect of machinery and apparatus in duo to transient phenomena and overload on operation. Particularly by advanced technology of late, there is demand for low cost of equipments and high percentage of use of equipments. Therefore, protection of machinery and apparatus in condition of overload is more valued considering that all efficiency increase is passed by operating all machinery and apparatus in condition of heavyload. In this paper, the suggested system is add overload protect system using CT in condition of overload.

  • When fault occur in power systems, the protective relay plays a roles of protecting power system according to its setting values. There, it is very important that the protective relay have high selectivity performance in power system by correct setting the relays. This paper analyzed protect device protect cooperation or Transient stability and apply to Overcurrent relay in the real power system operation environment by using EDSA Program.

  • It is one of important techniques to protect illegal uses and forgeries for text databases when the internet has become widsepread. Lots of studies and system developments has been progressed in order to protect text databases, important documents of the companies, and blueprints of the research institutes. Given this project securing the KISTI (Korea Institute of Science and Teschnology Information) digital contents, we are to design a watermaking and fingerprinting system protecting document images, and a agent notifying the traitors' location.

  • Purpose: The purpose of this study is to research to protect to loss of chrome-plating of small arms barrel on high temperature in order to extend its life expectency. Methods: The reason why chrome-plating dropped out is main material is weak from heat. Therfore, to make barrel of small arms have higher heat-resistant property, nitriding for barrel before chrome-plating is needed and test of that barrel was handled to improve it. Results: Nitriding before chrome-plating is useful to protect to chrome-plating loss on high temperature. Conclusion: To protect loss of chome-plating of small arms barrel during on firing, pre-nitriding on barrel is effective finally it leads to extend to barrel's life expectency.

  • The cyber attacks on the computer system in nowadays are focused on works that do not operate specific application. The main key point that we protect information security system has an access control to keep an application. Most of system has a main function to protect an infrastructure such as hardware, network and operating system. In this paper, we have presented an intrusion tolerance system that can service an application in spite of cyber attacks. The proposed system is based on the middle ware integrating security mechanism and separate function of application and intrusion tolerance. The main factor we use security system in nowadays is service to keep a persistency. The proposed intrusion tolerance system is applicable to such as medical, national defense and banking system.
