This study analyzed the inter-regional productivity performance of Southeast region of Korea, namely, Busan, Daegu, Ulsan, Gyeongbuk, and Gyeongnam for 16 service sectors, which are categorized by two groups, knowledge based service (5 sectors) and non-knowledge based one (11 sectors) for the period of 1997-2004. This study applied the method of Malmquist productivity change index(MPI) to the estimation of spatial productivity. According to the estimation results, firstly, the MPI of service sector has been deteriorated by annually 0.1% on average. However, when we divided the period into 1997-2000 and 2001-2004, the productivity performances of the second period was better than that of the first period, which are the same trend in knowledge based and non-knowledge based service sectors. Secondly, comparing productivity performances by region and sector during the whole period, Daegu has seven sectors which are relatively comparative advantage. and Ulsan and Busan have six and five sectors, respectively, which are relatively comparative advantage.

This study measures the relative efficiency and productivity change of IT firms received policy fund using DEA model and Malmquist Index for 2006-2007. The main results of this study can by summarized as follows. First, in case of efficiency of CCR for 2006-2007, the number of efficient firms(CCR value is one) are six firms, six firms, respectively. Second, in case of efficiency of BCC for 2006-2007, the number of efficient firms(BCC value is one) are eleven firms, thirteen firms respectively. Third, In case of return to scale for 2006-2007, DRS are fifteen firms and fourteen firms respectively. IRS are two firms and one firm respectively. DRS firms can improve efficiency by the reduction of scale and IRS Firms can improve efficiency by the increase of scale. Fourth, Mean value of Malmquist Index representing productivity change for 2006-2007 are bigger than 1.00. This imply that productivity increase was achieved.

본 논문은 도로 건설 공사 프로젝트들의 전 공정에 걸쳐 수행되는 모든 작업들을 대상으로 총 프로젝트 생산성 (Total Project Productivity)을 측정하고 분석하기 위한 방법을 소개한다. 측정 방법의 주안점은 복합적으로 병행되는 작업들의 생산량을 통합하여, 프로젝트 전체에 대한 포괄적인 생산성 값들을 구하는 방법을 개발하는데 두고 있다. 이 방법을 통해 Florida Department of Transportation (FDOT)로부터 발주된 세 개의 실제 고속도로 건설 공사 프로젝트들로부터 수천 개의 총 프로젝트 생산성 데이터 값들이 얻어졌으며. 이를 바탕으로 프로젝트 생산성을 분석하기 위한 방법의 타당성 검증이 이루어졌다. 그 결과로, 프로젝트 레벨에서의 총 생산성은 건설 작업들에 관한 현장 자료를 바탕으로 측정과 분석이 이루어질 수 있음이 입증되었다.

이글은 대의민주주의에서의 입법 메커니즘에 대한 이론적 논의를 전개한다. 이러한 논의를 근거로 한국 국회의원의 입법생산성에 영향을 미치는 변수들을 도출하고, 이 변수들이 16대와 17대 국회의 입법생산성에 미치는 효과를 분석한다. 이글의 경험분석은 국회의원의 입법생산성은 이들의 학력, 법조경력, 관직경력, 의정경력 같은 개인적 배경과 서로 무관하다는 사실을 보여준다. 이글의 경험분석에 의하면, 국회의원들의 개인배경보다는 원내 정당간의 역학관계와 소속정당의 여당지위, 그리고 의회요인들이 국회의원들의 입법생산성에 영향을 미치는 것으로 밝혀졌다. 이러한 분석결과는 한국 대의민주주의의 작동과 관련된 함의를 제공한다. 국회의원의 입법활동에 대한 정보를 접하기 어려운 환경에서는 국회의원의 개인배경에 의존하는 국회충원 방식이 대리인문제를 유발할 가능성이 높다. 이글은 국회의원 입법활동에서 발견되는 대리인 문제의 해소를 위한 제도적 방안들에 대해 논의한다.

CMMI is composed of 22 process areas by 5 maturity levels and each process area consists of specific goals and generic goals. Since there are many relations among process areas, organizational standard processes tend to contain overlapped contents. In this paper we demonstrated that 60 out of 528 specific goals are highly related (11% relationship) in CMMI maturity level 3 process areas by using pearson correlation analysis and proposed to a scheme for defining organizational standard processes based on the results. As a result of defining organizational standard processes by using proposed a scheme, we achieved a significant improvement of 25% in process defining productivity.

This paper evaluates the effects of privatization and deregulation on the firm-specific efficiency and total factor productivity (TFP) growth in the Korean and Japanese railways. Using a stochastic frontier approach and a generalized translog functional form, the paper specifies the equation system consisting of a multiproduct variable cost function and input share equations which is estimated with Zellner's iterative seemingly unrelated regression and the corrected least squares method. The Korean and Japanese railway firms are assumed to produce three outputs (Shinkansen passenger-kilometers, incumbent railway passenger-kilometers, ton-kilometers of freight) using three input factors (labor, fuel, maintenance and rolling stock). A monetary value of the ways and fixed installations held by the railroad firm is also included as a quasi-fixed input. The empirical results indicate that the average estimate of cost inefficiency is 2.57% for the total sample and on the average, JNR and JR Kyushu are found to be worst efficient while the most efficient railway firm in the sample is JR West. Also the cost efficiency levels of seven JRs have been improved after the reform and privatization of JNR. The findings also indicate that TFP growth of the privately-owned JRs are higher than those of the government-owned KNR and JNR. Three-island JRs and JR Freight have slightly higher TFP growth than Honshu JRs as well. Thus, the results suggest that managerial autonomy and increased competition via deregulation have improved efficiency and TFP growth.

This study public hospital productivity and private hospitals, comparative analysis was divided into capital productivity, labor productivity, value-added productivity, based on the findings public hospitals are able to ensure the public interest to provide stable and profitable health services of good quality. It proposes measures to improve productivity. Investigation period were based on the fiscal year 2013, the target of 39 public hospitals are private hospitals surveyed were selected for a total of 147 hospitals with 108. ANOVA analysis was performed the analysis, hierarchical regression analysis. In the conclusions showed as the most important factor in the profitability of labor productivity, the productivity of public hospitals variables, because exert a significant impact on the productivity and efficiency of future public hospitals are required to establish an effective personnel management system. It should also Productivity and specific assessment of the effective management be analyzed by the association between the margins would have to be.
