비영리조직의 자원동원에 관한 기존의 연구들은 조직리더의 역할 및 환경에 대한 인식 등을 주요한 요인으로 제시하며, 점차 이러한 요인이외에 조직의 체계적인 관리노력으로서 시장지향성의 중요성을 제시하기도 한다. 본 연구는 사회복지조직의 자원동원성과를 설명하는데 있어서 조직리더의 전문적 태도, 환경에 대한 인식 그리고 기부자에 대한 시장지향성 간의 구조적 관계를 분석하는 것을 목적으로 한다. 이를 위해 전국에 위치한 장애인직업재활시설로 연구표본을 구성하고, 설문조사에 응답한 115개 조직을 분석하였다. 분석결과, 자원동원성과는 조직리더의 전문성이나 환경에 대한 인식에 의해 직접적으로 영향을 받지 않으며, 기부자에 대한 시장지향성을 매개로 하여 간접적으로 영향을 미쳤다. 본 연구는 일반화의 한계에도 불구하고, 자원동원성과에 영향을 미치는 요인들간의 구조적 관계를 보여주고, 자원동원성과를 설명하는 간명한 경로를 제시하였다는 점에서 학문적 의의를 지니며, 실천적인 측면에서 사회복지조직의 자원동원에 있어서 기부자를 체계적으로 관리하는 것이 중요하다는 점을 보여주고 있다.

Deregulation in power industry has made the reactive power ancillary service management a critical task to power system operators from both technical and economic perspectives. Reactive power management in power systems is a complex combinatorial optimization problem involving nonlinear functions with multiple local minima and nonlinear constraints. This paper proposes a practical market-based reactive power ancillary service management scheme to tackle the challenge. In this paper a new model for voltage security and reactive power management is presented. The proposed model minimizes reactive support cost as an economic aspect and insures the voltage security as a technical constraint. For modeling validation study, two optimization algorithm, a genetic algorithm (GA) and particle swarm optimization (PSO) method are used to solve the problem of optimum allocation of reactive power in power systems under open market environment and the results are compared. As a case study, the IEEE-30 bus power system is used. Results show that the algorithm is well competent for optimal allocation of reactive power under practical constraints and price based conditions.

Facility-based competition (FBC) in the telecommunications market is considered to have lower static efficiency in the short term and higher dynamic efficiency in the long term. Under service-based competition (SBC), the entrant can reduce its setup costs by leasing network facilities from the incumbent, which makes the entrant viable, pushes the market price down and promotes static efficiency. This paper attempts to measure static efficiency by comparing the profits of the incumbent and entrant in terms of consumer surplus and social welfare under each competition type by extending the Stackelberg model. The results, assuming a linear demand function and variation in regulatory level, show that FBC results in higher social welfare than SBC on the whole. However, SBC accompanied by strong regulation is also shown to have the potential to be superior over FBC. It is also revealed that FBC exhibits a higher producer surplus (particularly, the incumbent's producer surplus) and is, therefore, more desirable in terms of dynamic efficiency. When the entrant's cost is high in FBC, social welfare is shown to be lowered, implying that cost competitiveness is a necessary condition for social welfare.

This paper uses Delphi Method and statistics provided by the State Administration of Market Regulation of China, attempts to develop the scale index of language service industry in China. Coupled with practical investigation and theoretical framework of SCP paradigm, a deep analysis on market behavior, market structure, and market performance of the industry have been explored. First, the study indicates that the scale index of Chinese language services industry has experienced an upward trend from 10.481million RMB in 2008 to 351.403 million RMB in 2017. Second, majority of language services enterprises are situated in Chinese coastal provinces and there are variations in demand for language services. Third, the standardization of language services are minimal while most of the talents involve a single discipline background. Fourth, most enterprises utilize language tools while there is lack of technological innovation for utilization of language resources and enhancement of service quality. The author mainly suggests four strategies which include: cultivating multilingual services, strengthening the development of industrial informatization and technical innovation, and optimizing the industrial talents structure while also adjusting for industrial distribution and regional coordination, which propose the meaningful implications for the development of language service industry in China.
