This paper tries to show the efficiency of water financing between central and local governments. From the year of 2017, the operation and maintenance costs for change water pipes has been provided by central government as block grants system(RDSA: Regional Development Special Account). Even though the water financing is responsible for local government, water drought and high production cost in poor area affects the quality of life nowadays. Then, fiscal transfer through block grant for water financing has been decided to invest regional SOC. The purpose of the paper sheds light on the function of the block grant for public provision by water financing. The firstly tried empirical results are based on the survey from local governments and ministry of environments. The point of the empirical analysis shows that the local governments does not have proper measurement for unexpected water leakage and termination until now. In a policy manner, the paper raises the issues about benefit principle for water users by the increase of tariffs. In order to do so, the paper investigates the relationship between the water provision and fiscal status of each local governments.

A comparative study on dynamic and static measurement of initial stiffness was conducted. Because soil stiffness decreases even at very small strains, the initial stiffness has been measured by dynamic tests using shear wave velocity measurement. On the other hand, due to the advance of local strain measurement, the triaxial testing device is capable of measuring the static initial stiffness. It has been known that initial stiffness measured by static triaxial tests is generally lower than that measured by dynamic tests possibly due to the limitation of static measurement of displacement at very small strains. This study presents experimental results indicating that the elastic shear moduli could be the same both in dynamic and static measurements owing to the soil anisotropy induced by anisotropic stresses.

In conventional methods for measuring snow height, a graduated pole is installed on ground in an area of interest and the snow height is manually read from the pole. Recently, automated snow height measurement systems have been introduced to improve the conventional methods. The automated measurement systems, however, are quite expensive since they use the reflection of ultrasonic waves or laser beams. In addition, it is not easy to move the location of the automated measure systems. This paper proposes a snow height measurement system equipped with image sensors and wireless communication capability via a USN and the Internet. The proposed system has a resolution of 5 cm and easy to deploy without difficulties, which can be usefully used to monitor unforseen local snowfalls.

이 연구는 지방공무원들의 역량강화 정책을 설명하고, 제한된 자원의 한계 속에서 효율성을 높일 수 있는 정책과제를 도출하는데 있다. 이를 위해 AHP분석 기법을 적용하여, 전문가 평가를 통해 정책과제의 상대적 우선순위를 도출하였다. 연구결과는 다음과 같다. 첫째, 지방공무원 역량강화를 위한 가장 큰 틀에서의 정책과제에서는 지방공무원 직무관리가 가장 중요하게 평가되었다. 다음으로 지방공무원 채용관리, 지방공무원 인사관리의 순으로 평가되었다. 둘째, 세부정책에 대한 평가 결과이다. 지방공무원 직무관리 중에서는 지방공무원 안식기간제 도입이 가장 중요하게 평가되었다. 지방공무원 채용관리에서는 공무원 시험과목 개편이 가장 중요하게 평가되었다. 지방공무원 인사관리에서는 선출직 공무원들에 대한 직무교육훈련이 가장 중요하게 평가되었다. 이러한 연구결과는 지방공무원 역량강화를 위한 정책개발을 현실적 측면에서 설명하는데 도움을 줄 것으로 사료된다. 향후 지방공무원 역량강화를 위해 측정변수들의 분석이 더욱 필요할 것으로 판단된다.

It is well known that the electrical impedance of biological tissues is very sensitive to their temperature. In this paper, we have analyzed the effects of temperature change on the phase of magnetic resonance images obtained with external current injection. It has been found that the local phase in the current injected magnetic resonance image can be changed noticeably when local temperature change appears at a part of the tissue. At the experiments with a 0.3 Tesla MRI system, we observed the local phase changes at the phantom images when the phantom temperature was varied between 25 -45$^{\circ}C$. We think that the current injection MRI technique can be used for in-vivo monitoring of the temperature inside biiological tissues if the relation between the local temperature and phase can be quantified.

This paper presents a structure of the retail electricity market based on the local pool with LDERP(Local Distributed Energy Resource Provider) for small energy prosumers. LDERP is an operator for the proposed market, which conducts performance measurement and settlement by the distribution plan determined through contract with participants. The trading process is designed similarly to the negawatt market. In the case study, the many-sided conditions of the proposed market are comparatively analyzed with the existing prosumer programs. The results demonstrate the effectiveness of the proposed framework in determining the purpose of market operating for the benefit of participants according to the various situations.
