The purpose of this study is to investigate communication style & communication in the family and marital satisfaction. This study focuses on the following aspects: 1) to find out which variables of background variables(oe, sociodemographic variables & communication styles) have effect on communica-tion and marital satisfaction in the family. 2) to find out the relationships between communication in the family and marital satisfaction. 3) to find out the independent influence of background variables on marital satisfaction. In order to clarify the above problems the data were obtained from questionaires with 72 items. The selected sample is composed of 365 housewives in chong Joo city. SAS pc program was used for th statistical analysis of the data. Data was analyzed by frequency percentage mean F-test Duncan's multiple range test regression analysis path analysis pearson's correlation coefficient. Major findings are as follows: first age of couples education of couples durati n of marriage family life cycle number of children income were variables to have influence on communication in the family, And communication styles were variables to have influence on communication in the family. Second age of couple education of couple duration of marriage family life cycle number of children were variables to have influence on marital satisfaction. And communication styles were variables to have influence on marital satisfaction. Third there were positive relation between communication in the family and marital satisfaction. The higher communication about clothing food housing skill health affection money, time and infstitutional facilities the higher marital satisfaction. Fourth influential variables related to marital satisfaction were communication about clothing affection & money and communication styles(ie, random style, morphogenic style, mophostatic style)

With the development of information and communication technology, various data have appeared and are being distributed. The use of various data has contributed to the enrichment and convenience of our lives. Data in the public areas is also growing in volume and being actively used. Public data in the field of education are also used in various ways. As the distribution and use of public data has increased, advantages and disadvantages have started to emerge. Among the various disadvantages, the privacy problem is a representative one. In this study, we deal with the privacy issues of public data in education. First, we introduce the privacy issues of public data in the education field and suggest various solutions. The various solutions include the expansion of privacy education opportunities, the need for a new privacy protection model, the provision of a training opportunity for privacy protection for teachers and administrators, and the development of a real-time privacy infringement diagnosis tool.

Detection of data cleaning bed of because method of communication uses AODV(Ad hoc On-demand Distance Vector) Zig-Bee communication though communication method is important being separated by several part structurally data monitor ring do it way to understand be. Although data that detect in transmitter will get into several kinds, data of each senses is detected by 4 - 20 mA conclusively and remainder data is consisted of temperature data. That is measured in transmitter in mast baud via conversion relation to do monitorring norm of data being decided to PC mistake of measured value so that can do control between enforcement compose. Speak that can manage equipment of cleaning bed by number of persons who write if detect data detection in wide cleaning bed through Zig-Bee communication and is easy because also administration of data consists of real time.

In this paper, TCP/IP based Machine-to-Machine (M2M) communication uses CDMA/GSM network for data communication. This communication method is widely used by offshore moored buoy for data transmission back to the system server. Due to weather and signal coverage, the TCP/IP M2M communication often experiences transmission failure and causing data losses in the server. Data losses are undesired especially for meteorological and oceanographic analysis. This paper discusses a software approach to minimize M2M data losses by handling transmission failure and re-attempt which meant to transmit the data for recovery. This implementation was tested for its performance on a meteorological buoy placed offshore.

It is recently trend that local government which introduce the BIS is increasing steadily. Communication is inevitably necessary to offer a data of a collected bus position to transportation center and supply construed information. Until now, most BIS connection research is actively in data of collecting, processing, offer but Research is Relatively insufficient on communication mode to connect it. Therefore, this study is achieving applicable communication mode on BIS of present common use inning that communication mode. Study resulting, characteristic of BIS communication mode is analyzed that send-receive of short packet data happens frequently and It is inevitably necessary to synthetically analyze economical side, authoritativeness side of communication, introducing communication mode.

We propose a high speed data communication method for motor drive systems with fast control cycle in order to collect state variables of motor control without degrading control performance. Ethernet is chosen for communication device, and multi-core DSP architecture is exploited for communication processing load distribution. The communication program including network protocol stack and motor control program are assigned to two separate cores, and data between two cores are exchanged using interrupt-based inter-process communication mechanism, which enables to achieve a high-speed communication performance without degrading the motor control performance. The performance of developed communication method is demonstrated by real experiments using TCP, UDP and Raw Socket protocols in an experimental setup consisting of TI's TMS320F28388D motor control card and MS Windows PC.

Large sensor networks require the collection and analysis of data from a large number of sensors. The number of sensors that can be controlled per micro controller is limited. In this paper, we propose how to aggregate sensor data from a large number of sensors using a large number of microcontrollers and multiple bridge nodes, and design and implement an efficient communication system for sensor data collection. Bridge nodes aggregate data from multiple microcontrollers using SPI communication, and transfer the aggregated data to PC servers using wireless TCP/IP communication. In this paper, the communication system was constructed using the Open H/W Aduo Mini and ESP8266 and performance of the system was analyzed. The performance analysis results showed that more than 30 sensing data can be collected per second from more than 700 sensors.

This paper deals a watt-hour meter monitor system with applying a Power Line Communication (PLC) modem and a Data Concentrator Unit (DCU). PLC modem uses the power line, so there is no need to install dedicated wiring. This system makes it possible to monitor the amount of electricity of previous current month metering data, so it can easily apply a PC-management for the electric charges and maintenance with gathering the metering data.

In this paper, we present the Tele-consulting system of radiology, which uses the communication network as asymetric satellite data communication system. The asymetric satellite data communication system uses receive-only satellite links or data delivery and PSTN(Public Switched Telephone Network) modem or N-ISDN(Integrate Services Digital Network) for communication. The satellite communication linking shows the very high-speed performance than 28.8kbps modem linking. The satellite linking is 5 - 10 times aster than the modem linking. Consequently, we get the conclusion that our system is suitable or tele-radiology and telemedicine.
