This study was done in order to analyze the factors which influenced the performance level of urban family planning health personnels' task. Interview survey was done during the period May, 1989. Interviewee were 130 family planning health personnels among total of 140 family planning health personnels in Seoul metropolitan city area. The internal consistency reliability was tested by Cronbach’s Alpha and the construct validity of the survey tool was tested by Factor analysis. Multiple stepwise regression analysis was used to identify major factors influenced to perform family planning health personnels' task. The results of this study were summarized as follows: 1. The internal consistency reliability was high and very significant (Cronbach's Alphs=0.8445, p<0.0000). 2. The construct validity was high and very significant. This analysis was contained 5 factors; registering and keeping of eligible woman records, health educating for FP & MCH, referral for vasectomy and tubal ligation and loop, supplying contraceptive appliances, sending moved-out eligible woman records. 3. Among a total of 15 contents of their functions recording of daily report and monthly report (76.2%), classifying and keeping of records(66.2%), registering of eligible woman records(60.85ti), distribution of leaflets and pamplets(54.6%), counselling & supervision about family planning(53.8%) were actively performed. Sending moved-out eligible woman records(60.8%), health education for community people(49.2%), referring contraceptors' side-effects were poorly performed. 4. The factors which influenced the performance level of urban family planning health personnels' function were age, marital status, educational level, certification, number of residents, number of eligible women, job car-eer, work responsibility, job satisfaction knowledge, position, cooperation of community people, cooperation of Dong Office, cooperation of Health Center. These 14 variables were able to explain job function from 21.4% of follow-up care of contraceptor to 9.1% of classifying & keeping of eligible woman records.

This article is about using information technology to apply with water loss inspection system in District Metering Area (DMA). Inspector can check Flow rate and Minimum Night Flow; NMF via Smart Phone or PDA include sending SMS Alert in case the Pressure, Flow rate and NMF is over the range of controlling. This will be used as equipment to implement water loss in international proactive and can keep on water loss reduction more efficiency. The system consists of Data Logger which collects data of Flow rate from DMA Master Meter. PC is Wap Server which dial via modem in order to get data through FTP Protocal that will convert text file to Microsoft Access Database. Wappage will use xhtml language to show database on Wapbrowser and can show the result on Smart Phone or PDA by graph and table for system analysis.

Lately the usage of multimedia equipment with small LCD displays is rapidly increasing. Although many people use devices like cell phone and PDA, videos intended for TV or HDTV are sent to these mobile devices. Therefore, situation where it is hard for the user to view the desired scenes are growing more frequent. Currently, most services simply reduce the size of the content to fit the screen when they offer it for mobile devices. However, especially with sports broadcasts, there are many areas that cannot be seen very well because it was simply reduced in size. We are suggesting new motion how to let the user choose an area of interest based on Cognitive lattice. And present then sending it to the user in a way based on Focus Of Choice that fits the device.

The field of body sensor networks has attracted interest of many researchers due to its potential to revolutionize medicine. These sensors are usually implanted inside the human body and communicate among themselves. In the process of receiving, processing, or transmitting data, these devices produce heat. This heat damages the tissues surrounding the devices in the case of prolonged exposure. In this paper, to reduce this damages, we have improved and evaluated two protocols-the least temperature routing protocol and adaptive least temperature routing protocol-by implementing clustering as well as a leadership rotation algorithm. We used Castalia to simulate a basic body area network cluster composed of 6 nodes. A throughput application was used to simulate all the nodes sending data to one sink node. Simulations results shows that improved communication protocol with leadership rotation algorithm significantly reduce the energy consumption as compared to a scheme without leadership rotation algorithm.

In the 21 st century, broadcasting, communication, and computer have been integrated due to the development of digital technology. Accordingly, to overcome the limit of respective communication media and to maintain them, their independent area shall not be classified. This study is to examine the future environment of digital TV broadcasting, to analyze customizing type service and interactive type TV technology, and to make asymmetric interactive digital TV publication broadcasting system, which is TV broadcasting in the next generation to treat visual image, sound, and various data all together by harmonizing broadcasting and communication like ISDB(Integrate Service Digital Broadcasting). In addition, to develop service on publication broadcasting with high quality, this study is tn propose to develop relative devices for TV/PC reception to realize a new communication type TV publication broadcasting, by analyzing technology for producing, sending, transmitting, receiving, and saving to apply to customizing type interactive system and by examining its application.

In this paper, presents the design of mobile field robot controlled by microcomputer. The computer works as the supervisory system for decision making and sending command to control the field robot. An information from encoder, infrared sensors using for control task of the robot that can be interconnected with the computer through the serial communication RS422 standard. In this case, the user can design the program algorithm base on microcomputer in order to control and define the routing of the mobile robot. Moreover, the robot can be installed other equipment fer collect data such as picture, sound, temperature etc., in order to working in the dangerous area.

The input and output impedances in a low voltage distribution system is one of the most important matters for power line communication because from the viewpoint of communication, the attenuation characteristic of the high frequency signals is greatly caused by impedance mismatch during sending and receiving. The frequency range is from 1MHz to 30MHz. Therefore, this paper investigates the input and output impedances in order to understand the characteristic of high frequency signals in the low voltage distribution system between a pole transformer and an end user. For power line communication, the model of Korea's low voltage distribution system is proposed in a residential area and then the low voltage distribution system is set up in a laboratory. In the low voltage distribution system, S parameters are measured by using a network analyzer. Finally, input and output impedances are calculated using S parameters.

We present a simple algorithm for detection of red patches by remote sensing in coastal waters of Korea. The red tide patches can by identified by the relative intensity of red band signal with respect to the blue-green background signal, provided the radiometric signals only in the sea area are properly stretched. We tested our algorithm by Ocean COlor Monitor(OCM) data of Indian Satellite IRS-P4, which has been received from 2001 by National Fisheries Research and Development Institute of Korea. A comparison of our results with observation shows that the locations of red tides derived from remote sending imagery by our algorithm are in accordance with observations.

MMOG는 네트워크 가상 환경의 다양한 응용 중 하나이며, 수백 명 이상의 사용자들이 동시에 가상 세계에서 상호작용한다. P2P MMOG에서 대역폭 소비를 줄이기 위하여 VON 기법이 제안되었으며, Message Forwarding을 이용하여 성능을 개선한 Vorocast 기법도 있다. 본 논문에서는 Forwarding 모델 상에서 메시지를 발생하는 노드가 더 많은 이웃 노드들에게 위치 갱신 (Position Update) 메시지를 전달하는 방법으로써 적은 일관성이나 높은 지연성과 같은 문제를 개선한 동적 관심영역 (AOI : Area Of Interest) 관리기법을 제안한다. 제안 기법은 Direct-Connection 모델과 Vorocast 모델을 결합함으로써 기존의 기법과 비교해서 보다 높은 일관성을 제공하고 지연성을 감소시킨다. 시뮬레이션을 통하여 제안 기법의 성능을 보였다.
