This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.

Water quality improvement was predicted by using ecological modelling with reference to reduced load pollutants in the Busan coastal area. The results showed appreciable improvement in water quality at Suyeong Bay and Nakdong Estuary but little improvement in water quality from the central to eastern regions, except in Suyeong Bay by COD concentration. There were also similar results for T-N and T-P, because the Busan coastal area has a more open boundary than the other bays in the South Sea of Korea, resulting in a fast flow rate. The reducted COD load was less than that found in other coastal areas. Also, the reduction rate of the total load was less than that of other coastal areas in terms of water quality improvement. Applying the reduction load estimated in this study, it should be possible to improve the water quality of Suyeong Bay and Nakdong Estuary.

This paper describes performance improvement of GPS/DR Integration system using area decision algorithm and vehicle movement information. In GPS signal blockage area, i.e., tunnel and underground parking area, DR sensor errors are accumulated and navigation solution is gradually diverged. We use the car movement information according to moving area to correct the DR sensor error. Also, vehicle movement is decided as stop, straight line, turn and movement changing region through DR sensor data analysis. The car experiment is performed to verify the supposed method. The results show that supposed method provides small position and heading error than previous method.

This study analyzes the problems, which the residential inner area has, and proposes systematic and gradual progressing improvement plan for the residential environment in the inner area. Also, planning instruction is proposed through the case study of parcel·jointed complex housing. This study can be concluded as below: (1) Improvement plans sub-divided into promoting districts and inducing districts of the residential inner area are proposed. (2) Necessity for construction of streets is proposed in order to compensate existing problems in sites. (3) Necessity of complex housings is proposed fur roadsides of household unit or small-sized annexation of parcel. (4) Collecting design examples and existing literatures, the planning guideline for jointed parcel complex housing is proposed based on the established relation with a whole surface of streets, formation and distribution of purposes and increased role of exterior space.

In this paper, an optimal approach for the wide-area regulation of control devices in a transmission network is proposed. In order to realize an improved voltage profile and reduced power loss, existing devices such as tap-changing transformers, synchronous machines, and capacitor banks should be controlled in a coordinated and on-line manner. It is well-understood that phasor measurement units in transmission substations allow the system operators to access the on-line loading and operation status of the network. Accordingly, this study proposes efficient software applications that can be employed in area operation centers. Thus, the implanted control devices can be regulated in an on-line and wide-area coordinated approach. In this process, efficient objective functions are devised for both voltage profile improvement and power loss reduction. Subsequently, sensitivity analysis is carried out to determine the best weighting factors for these objectives. Extensive numerical studies are conducted on an IEEE 14-bus test system and a real-world system named the Azarbayjan Regional Transmission Network. The obtained results are discussed in detail to highlight the promising improvements.
