This article intends to explore the formation of furniture terms with the name of furniture, furniture materials, tools, and machinery from eight furniture companies manufacturing their own different furniture items. As a result of this study, the terms can be abstracted as four things as follows. First of all, the terminology that the furniture firms is are unified over 80 percent and has no problem on the communication among the companies. Especially office furniture all is using common words because the terms are almost fixed by an administration agreement relating to the Supply Administration. Second, the furniture terms being used at the fields are mixed with Korean, English, and Japanese, and this current state shows more at small businesses than at large businesses Third, the terms of foreign words, almost English, present 48 percent as 156 words among the total 325 terms. Japanese shows 6 percent as 21 terms but it tends to be handed down from mouth to mouth with inaccurate conditions. Finally, the formation of the terms are from the original words or English, from the combination of Korean and foreign words for convenience at the fields, and from being created as Korean newly in considering Korea's special situation.

Handoff if the most Important feature for the user's mobility in a cellular communication system, which is related to resource reservation at nearby cells. For efficient resource reservation, mobility prediction has been reported as an effective means to decrease call dropping probability and to shorten handoff latency in wireless cellular environments. Several early proposed handoff schemes making use of tile user's movement history on a cell-by-cell basis work on the assumption that the user's movements are restricted to the indoor locations such as an office or a building. However, those algorithms cannot be applied to a micro-cell structure or a metropolis with complicated structure of roads. In this paper, to overcome those drawbacks we propose a new mobility prediction algorithm, which stores and uses the history of the user's positions within the current cell to predict the next cell.

The recorder at observatory can save the measured data from water gauge and rain gauge at an interval of five minutes. And then, the RTU (Remote Terminal Unit) in observatory sends the measured data in the recorder to the TM (Telemetering) in FCO (Flood Control Office) at an interval of ten minutes using VHF or satellite communication. But the transmitted data is not the stored data at the recorder, it is just data that is measured at an interval of ten minutes. In the FCO, the transmitted data is analyzed in order to forecast the flood. And also one of the most important things is the maintenance of an observatory. In this paper, an effective management system for the flood forecast is proposed. It uses the CDMA and the Blutooth technology on PDA. The proposed system is very portable, and also easily able to send the data stored at the recorder in observatory to TM in FCO without RTU. And it allows us to view remotely the data of other observatories by downloading from the FCO. Hence the system can do efficiently the maintenance of observatory without wasting manpower and time.
