Service productivity is a brand new concept in the service industry, since it is quite different with conventional productivity. While the productivity in manufacturing is one of the quantitative measures for evaluating process efficiency, the service productivity include the nature of customer satisfaction as well as those of service process efficiency. Customer satisfaction, also called service quality in the service industry is one of the most difficult factors to measure quantitatively due to its intangibility. Hence it is also difficult to measure the service productivity correctly. It is hard to find the existed models for service productivity or related research papers in the literature. In this study, a new model which can be used to measure and evaluate the service productivity considering both the service quality and the productivity of service process is proposed. AHP, one of the well-known multiple-criteria decision-making methods, is applied to deal with both quantitative and qualitative factors in the model. The methodology and the procedures for measuring and evaluating service productivity are also presented.

This paper proposes a standard open source software development guidance and an evaluation index for the productivity related to Seam 2.0 and Spring 2.5 framework. However, there is no comparison research about the performance of Seam 2.0 and Spring 2.5 framework with same identical platform. Quantitative analysis is supported as a part of LoC analysis. There is a limit to develop the updated software with no the specific evaluating index for the productivity of the software. This work proposes an specific index for evaluating the productivity of Seam 2.0 and Spring 2.5 framework on a platform. Base on the result, the specific guidance of the developing software is obtained.

The purposes of this study is to verify whether insider trader get the excess return using inside information. For this we divide inside traders into four groups according to their ownership: maximum shareholder, main shareholders, 5% sharehoders and executives. Also we categorize inside traders into three groups: personal investor, foreign investor and institutional investors. After insiders trade their stock, excess return is reported for 20days and the size of excess return of executives and institutional investor is larger than that of other groups. It means more strict monitoring system is needed in the domestic stock market.

In this era of knowledge and information of the 21st century, the source of a nation's competitive power consists of human resources and material resources and the importance of human resources appreciates highly. The number of small and medium enterprises which are the core of national economy covers over 98% among whole domestic enterprises of Korea. Competitive power of small and medium enterprises comes from human resources development. For the development of human resources, small and medium enterprises are trying to expand their learning organizations in the company. The analysis of outcomes of administering the existing learning organizations shows that learning organizations contribute highly to the improvement of the productivity of small and medium enterprises. And the analysis also shows that the participants of learning organizations and middle management and executives who support and encourage them recognize the necessity of learning organizations and that it should be disseminated throughout other enterprises. Therefore government's supports to establish learning organizations in a company are required to expand.

To explore the relationship of species diversity and aboveground productivity in grazing ecosystem is very important to manage grassland. We used the four years' data to check this relationship and to look how abiotic factor affect species diversity and aboveground productivity. We found a good linear relationship between species diversity and aboveground productivity in all previous grazing sites, while no any relationship was found in the no grazing site. From our results, we concluded that drought affects aboveground productivity more than grazing, while heavy grazing affects species diversity more than drought in Inner Mongolian steppe.
