Under high temperature and high pressure, cyanogen disinter gration distruction mechanism brought followings results through continuous plug flow reactor system. 1. The temperature was a important reacting factor in cyanogen disintegration. Over $612.8^{\cird}K$ high disintegration rate or 99.99% was shown even under $2000{\;}mg/{\ell}$ cyanogen density. 2. The conditions of cyanogen disintegration was gained through experimenting the supercrietical condition of water in basic. To gain 99.99% disintegration rate under $1000{\;}mg/{\ell}$ early cyanogen density, the pressure showed 52.8 seconds at $523^{\cird}K$ and 84.2 atm and gained $0.56{\;}mg/{\ell}$ operating density. 3. Here is the reaction velocity formula of cyanogen disintegration by hydrolysis: This formula indicates the high possibility of cyanogen disintegration within a short time. And it also implys the potential possibility on treating NBDICOD and the technology in developing the environment cleaning progress as small size automatic controlling equipment.

With the advent of the ubiquitous technology age, the progress of network technology has enabled a robust sensor communication, not just in cities, but also in poor surroundings such as deserts, polar regions, or underwater environments. In this paper, we propose a Multiple Acknowledgement (MA) technique to replace the conventional Automatic Repeat request (ARQ) technique. The MA mechanism is to send an Ack to many receivers simultaneously. The CH (master, coordinator) of the unit cluster broadcasts a Beacon frame where Ack information of the previously transmitted data is included. This technique can reduce the number of transmissions and overhead significantly. The proposed technique is a scheme improving the efficiency of an underwater sensor network where the uplink data transmission is the mainstream. The Performance of the ARQ, Block Ack, Pervasive Block Ack and the proposed method were compared with one another and analyzed. The proposed method showed significant performance improvement as compared with the ARQ, BA, and PBA in its channel efficiency.

The recent ERP and CRM is mostly focused on the conventional function performances. However, the recent business environment has brought the change in market due to the rapid progress of internet and e-commerce. It is mostly becoming e-business and spreading out as development of the relationship with other cooperating companies, the rapid progress of the relationship with customers, and intensification competitive power through the development of business progress in the organization. CRM(custom relationship management) is a kind of the marketing progress which forms, manages, and intensifies the relationship between the customers and companies to manage the acquired customers and increase the worth of customers for the company. It needs the system base which analyzes the information of customers since it functions on the basis of various information about customers and is linked to the business category such as producing, marketing, and decision making. Since ERP is extending its function to SCM, CRM, and SEM(strategic Enterprise Management), the 21 century s ERP develop as the strategy tool of e-business and, as the mediation for this, will subdivide the functions of CRM effectively by the analogic study of data. Also, to accomplish classification work of the file which in existing becomes accomplished with possibility work with an automatic movement with the user will be able to accomplish a more efficiently work the agent which in order leads the machine studying law, it is one thing with system feature.

Looking back at the last 10 years of the enactment of the Game Industry Act, the law was revised as a regulation rather than a promotion of the game. The objective of this study is to investigate where game regulation originated and derived through the history of those, and to find out what areas were missed, and to solve the tangled threads by regulation. For this purpose, we reviewed the implications of 10,000 won per hour, and discussed alternatives. Data were collected and analyzed on the basis of a review of regulatory literature and in - depth interviews with experts. When regulating games, we found that the side effects were further amplified by simply regulating the amount. Especially, we found that the vicious cycle in which functions such as indication, hit repeatedly, and automatic progress are made and immediately following prohibited is repeated. The point at which there is a sharp interest between the game user and the game operator in the game progression is the 'reward ratio for betting'. This is the key to protecting users. This could be a regulation considering the mechanism of the game. If the regulatory paradigm shifts in the future due to game regulations that take into account the 'reward ratio for betting' in the future, it is expected to minimize the side effects of price regulation and create a sound game ecosystem.

Using a high-rise building water piping after hydrostatic test of the reliability of the leak to be completed if the pressure is maintained until the leak is not commercially available considered. Due to the nature of high-rise buildings and the construction period will take several years from the lower levels of use of the water supply and fire fighting water pipe construction is in progress, the order of which I do most of the first pipe to the construction and more than three years. So kind of riser pipe is complete, install the valve in the basement by installing an automatic pump to maintain a constant pressure after hydrostatic test and after each floor plumbing piping is complete, the progress of the hydrostatic test without undergoing a separate branch pipe the valve is opened automatically when the number of the pressing pressure of the structure. I kind of do and keep working pressure of pipe until the completion of the construction work to keep the damage to human error when it is intended to prepare. In winter, the frost protection and an alternative to drainage water pipe is damaged or deformed, even if unaware of the finishing work to the building, the use of the damage caused by a leak in a after construction of finish work to be expected. Alternative to reduce this damage if the pressure test without fear of freezing to help maintain long-term commercial pressures may be considered.
