In order to improve the quality of life and support the successful living of the elderly people in rural community, the Senior Well-being Villages Project has been carried out by Rural Development Administration since 2005 in Korea. This timely project, however, produces good results with 582 villages so far, we must endeavor to upgrade it more effectively. This study is to find complementary way of improving the project, and the results of the study are summarized as follows. First of all, the sustainable and practical strategies of the health care for the rural elderly must be adopted. The elderly people's mutual care system can be a good option for improving the existing project. Secondly, the cooperative heath care system must combine with this project. In this regards, health cooperative federation system can be also a challenging option. The beneficially activity of rural elderly people, which is a component of this project, must be linked with rural social enterprise or community venture. The local experts or capable men of various fields including family, the aged problem, social welfare, and regional development, must be appointed, and the support system enables them to do their jobs actively in the Senior Well-being Villages Project as well as other community works.

Ramp metering is one of the most efficient and widely used control methods for an intelligent transportation management system on a freeway. Its objective is to control and upgrade freeway traffic by regulating the number of vehicles entering the freeway entrance ramp, in such a way that not only the alleviation of the congestion but also the smoothing of the traffic flow around the desired density level can be achieved for the maintenance of the maximum mainline throughput. When the cycle of the signal detection is larger than that of the system process, the density tracking problem needs to be considered in the form of the discrete-time system. Therefore, a discrete-time sliding mode control method is proposed for the ramp metering problem in the presence of both input constraint in the on-ramp and exogenous disturbance in the off-ramp considering the random behavior of the driver. Simulations were performed using a validated second-order macroscopic traffic flow model in Matlab environment and the simulation results indicate that proposed control method can achieve better performance than previously well-known ALINEA strategy in the sense that mainstream flow throughput is maximized and congestion is alleviated even in the presence of input constraint and exogenous disturbance.

Many Countries are making nationwide efforts to reduce the energy consumption which causes greenhouse gas emissions and global warming problems. Energy performance assessments and certification systems have been in force to save energy consumption of residential buildings, and are anticipated to have strong effects through the systems. Korean Building Energy Efficiency Rating System is in its early stages and is considered that the additional upgrade is needed for the accurate assessment. Thus, in this study, the assessment methods of the Building Energy Efficiency Rating System of Korea and the SAP2005 of UK were compared and energy requirements of an actual residential building were calculated with two assessment methods, respectively. The strengths and shortcomings of two systems were analyzed and a way of improving Korean system was suggested.

According to the recommendation of International Maritime Organization, the Ministry Of Maritime Affairs and Fisheries (MOMAF) of Korea provides the real time Differential Global Positioning System service using maritime radio beacon from 1999. Due to the benefit of DGPS service, the need of this system is increased from various user groups for acquiring the better accuracy and integrity. Therefore, MOMAF has extended their service to inland by installing the additional 6 DGPS stations. This nationwide DGPS service will be fully deployed at 2007. In addition to the extension of service area, MOMAF has a plan to upgrade their nationwide DGPS to High Accuracy Nationwide DGPS (HANDGPS). The planned HANDGPS service of Korea will be a kind of long range RTK or Wide Area RTK techniques to provide under 1m accuracy and start their service from 2009 using the various broadcasting and communication media like as radio beacon, Wibro, Digital Multimedia Broadcasting, High Speed Packet Data Access. The introduction of nationwide DGPS system of Korea and its evolution plan will be addressed in this paper. The research activities related with HANDGPS in Korea is also presented.

When researchers plan R&D projects, they usually use patent map or paper map for the objective decision-making, but in traditional korean medicine field, domestic patents and papers have been mainly proposed as results of many R&D projects, while most of patent or paper map tools support international patents and SCI papers, respectively. Therefore, as an alternative one KIOM constructed the project map which can provide the technology landscape for R&D project information in traditional korean medicine field. But the functions of the system is limited to the search and analysis with chart. So sophisticated analysis results are hard to get from the existing system. This research's goal is to upgrade the web based project map analysis system to provide researcher rich functionality and advanced analysis tools.

This paper presents constitution of a moderate price thermography system for on-line measurement. All objects with some temperature above absolute zero radiate in the infrared. The intensities and spectra of the infrared radiated from some object depend on the conditions and temperature distributions on the surface of the objects, and the temperature distributions differ from each others with different undersurface structures. Consequently, infrared radiation is useful for diagnosis of the conditions on the surface and undersurface of electric power apparatus. But the present, because engineers directly measure the temperatures of apparatuses in off-line, the measured data do not always have the information of the past. The proposed system is able to analyze not only the information of the past but the trend of deterioration, and the system is able to compensate for the distortion of surface temperature as to weather conditions. The thermal image histogram is equalized to upgrade observability, and a pan-tilter is adopted to control of direction for any target point.

The combined system of sequencing batch biofilm reactor (SBBR) and membrane SBR (MSBR) was operated with sewage to evaluate the COD utilization for biological nutrient removal (BNR). The SBBR was operated for nitrification reactor, while denitrifying PAO (dPAO) was cultivated in MSBR with anaerobic-anoxic operation. In the SBBR and MSBR system, the enhanced biological phosphorus removal (EBPR) was successfully achieved with higher N removal. The COD utilization in combined SBBR-MSBR system was significantly reduced compared to ordinary BNR (up to 3.1 g SCOD/g (N+P) and 1.6 g SCOD/g (N+P) with different C/N/P ratio). The results suggest that a dPAO process could effectively reduce carbon energy (=COD) requirement. The combination of oxic-SBBR and anaerobic-anoxic MSBR for dPAO utilization could be an attractive alternative to upgrade the process performance in weak sewage.

This paper presents a design methodology of a Digital Servo Signal Processor for high speed CD-RW drive systems. The proposed Digital Servo Signal Processor enables us to develop CD-related systems for the very high speed applications and is one of the key components of the CD-RW systems. The proposed center compensation servo control is newly built for an actuator shaking due to the fast response of a step motor when it jumps to a long distance. A control method compensating for eccentricity of a disc is implemented for operating robustly at a higher rotational speed. This servo mechanism is more size efficient and less power consumed because it is implemented using a ARM7 embedded processor and hardware digital filters. Furthermore, it is convenient to upgrade firmware for the future required functions. From experimental results, we can see that the performance of the control system is improved greatly. The proposed servo algorithm shows a shorter setting time including a pull-in time and a faster access time. It can be applied easily to the DVD-ROM and the DVD-RAM which have the same optical structure.

To upgrade the subjective question grading, we need the syntactic-semantic analysis to analyze syntatic-semantic relation between words in answering. However, since the syntactic-semantic tree has structural and semantic relation between words, we can not apply the method calculating the similarity between vectors. This paper suggests the comparing system with syntactic-semantic tree which has structural and semantic relation between words. In this thesis, we suggest similarity calculation principles for comparing the trees and verify the principles through experiments. This system will help the subjective question grading by comparing the trees and be utilized in distinguishing similar documents.

The number of final appeal(the rate of final appeal: 43%) has been on the increase every year over the past ten years in Korea. The number of final appeal cases given to a justice of the Korean Supreme Court amounts to nearly one everyday, which makes it vulnerable to faulty decisions. Reversal rate of final appeal is as low as 10% with most of the cases being dismissed and hence the percentage of people having trust in the judiciary is merely 27%. In this context, the Korean judiciary has announced its plan to set up a final appellate court in the Supreme Court. The establishment of final appellate court, however, is not only against the Constitution but also hardly seen in other nations. It would only overexpand the Supreme Court. Furthermore, the final appellate court would end up deteriorating into the court of fourth instance and impose extra burden on the government as well as on the disputing parties. Therefore, it is necessary to upgrade the quality of the court by increasing the number of judges in the lower court and let them focus on the fact finding process. Facilitating the ADR(Alternative Dispute Resolution) process such as arbitration would help improve the structure of the judiciary. The incompatibility among the four values of the dispute resolution process(equitability, truth, quickness and efficiency) calls for building comprehensive judicial system in which disputes are settled by choosing either jurisprudence or utility.
