This study analyzes the feng shui characteristics of the location of Seon-un Temple in Do-sol Mountain, Gochang from a metaphysical and selfish perspective through field research and literature review.A characteristic element of feng shui was that it prioritized harmony with nature and made it a reference point for selecting a location through a reasonable method. In the Silla Dynasty, adherent monks studied in the Gangseo area, where the Hyeongsepungsu first appeared, and this Hyeongsepungsu of the Gangseo District Law flowed into Korea and played a leading role in selecting the location of the temple and arranging Garam. Seon-un Temple was located under Do-sol Mountain and had no choice but to have great significance, and it was a practice of the desire to achieve Buddhist perfection through Do-sol Stream and Do-sol Small Temple, which enter the kingdom of Buddha. A s a result, the location of Seon-un Temple under Do-sol Mountain in Gochang reflected a variety of feng shui characteristics. In particular, the location of Sun-un Temple in Do-sol Mountain logically used the characteristics and meanings of feng shui and practiced becoming one with nature, which is aimed at spreading Buddhist doctrine and ideology, which has the holiest meaning of Buddhism.

The location selection for nuclear power plants (NPP) is a strategic decision, which has significant impact operation of the plant and sustainable development of the region. Further, the ranking of the alternative locations and selection of the most suitable and efficient locations for NPPs is an important multi-criteria decision-making problem. In this paper, the non-sequential Monte Carlo probabilistic method and the Latin hypercube sampling probabilistic method are used to evaluate and select the optimal locations for NPP. These locations are identified by the power plant's onsite loads and the average of the lowest number of relay protection after the NPP's trip, based on electricity considerations. The results obtained from the proposed method indicate that in selecting the optimal location for an NPP after a power plant trip with the purpose of internal onsite loads of the power plant and the average of the lowest number of relay protection power system, on the IEEE RTS 24-bus system network given. This paper provides an effective and systematic study of the decision-making process for evaluating and selecting optimal locations for an NPP.

In this paper, we propose two selection procedures for selecting populations better than a control population. The bestness is defined in terms of location parameter. One of the procedures is based on two-sample linear rank statistics whereas the other one is based on a comparatively simple statistic, and is useful when testing time is expensive so that an early termination of an experiment is desirable. The proposed selection procedures are seen to be strongly monotone. Performance of the proposed procedures is assessed through simulation study.

Earthmoving equipment's haul-route has a great influence on the productivity of the earth work operation. Haul-route grade is a critical factor in selecting the haul-route. The route that has low grade resistance contributes to increase machine travel speed and production. This study presents a mathematical model called "Hauling-Unit Optimal Routes Selecting system" (HUORS). The system identifies optimal path that maximize the earth-work productivity. It consists of 3 modules, i.e., (1) Module 1 which inputs site characteristic data and computes site location and elevation using GIS(Geographical Information System); (2) Module 2 which calculates haul time; (3) Module 3 which displays an optimum haul-route by considering the haul-route's gradient resistances (i.e., from the departure to the destination) and hauling time. This paper presents the system prototype in detail. A case study is presented to demonstrate the system and verifies the validity of the model.

In this study, we tried to analyze the suitability of factory development location in environmental aspects using the Green Development Suitability Map(GDSMap) which was created by GIS analysis about the optimal location of development projects. For this, it was evaluated a influence of various environmental factors that were caused by developments by setting the legislative, environmental and ecological assessment items. In addition, we made the GDSMap by reflecting the characteristics of region & development project overall. And, it were compared a location distribution on the GDSMap & NEZMap(National Environmental Zoning Map) to analyze a suitability of factory development location about the 39 factories located in study area. Results of analysis, the factory locations of about 23% of total development projects were confirmed that it was performed in development restrictions area on the NEZMap which was utilized current in selecting the location of development projects. And the factory locations of about 31% of total development projects could confirm that it was performed in development restrictions area on the GDSMap which was made in this study. Therefore, it was judged that it must be determined the development location by considering the characteristics of development projects & that region when selecting the location of various development projects.

This paper presents two distance geometry-based algorithms for wireless location in cellular network systems-distance geometry filtering (DGF) and distance geometry constraint (DGC). With time-of-arrival range measurements, the DGF algorithm estimates the mobile station position by selecting a set of measurements with relatively small NLOS (non-line-of-sight) errors, and the DGC algorithm optimizes the measurements first and then estimates the position using those optimized measurements. Simulation results show that the proposed algorithms can mitigate the impact of NLOS errors and effectively improve the accuracy of wireless location.

In group location management, when a transportation system(TS) with multiple mobile subscribers(MSs) changes location area(LA), location management is performed by group location registration by TS, instead of individual location registrations by MSs. In previous works, although it is assumed that LA in group location management is the same as that in individual location management, it is not appropriate to assume the same sized LAs since MSs in a TS have different characteristics from MSs which are not in a TS from the aspect of the speed and aggregate call arrival rates. Thus, in this paper, we propose an efficient location management scheme based on individual and group location managements with different sized LAs, and the performance of the proposed scheme is analyzed from the aspect of signaling cost at the wireless interface. Results reveal that the proposed scheme outperforms the conventional scheme by selecting an appropriate sized LA for group location management.

The problem of selecting base station location in the design of mobile communication system has been basically regarded as a problem of assigning maximum users in the cell to the minimum base stations while maintaining minimum SIR. and it is NP hard. The objective function of warehouse location problem, which has been used by many researchers, is not proper function in the base station location problem in CDMA mobile communication, The optimal and approximate solutions have been presented by using proposed object function and algorithms of exact solution, and the simulation results have been assessed and analyzed. The optimal and approximate solutions are found by using mixed integer programming instead of meta-heuristic search methods.
