The numbers of SCI paper or patent in science and technology are expected to be related with the number of researcher and knowledge stock (R&D stock, paper stock, patent stock). The results of the regression model showed that severe multicollinearity existed and errors were made in the estimation and testing of regression coefficients. To solve the problem of multicollinearity and estimate the effect of the independent variable properly, principal component regression model were applied for three cases with S&T knowledge production. The estimated principal component regression function was transformed into original independent variables to interpret properly its effect. The analysis indicated that the principal component regression model was useful to estimate the effect of the highly correlate production factors and showed that the number of researcher, R&D stock, paper or patent stock had all positive effect on the production of paper or patent.

새로운 소프트웨어를 개발할 때에 이미 개발되어진 소프트웨어를 재사용 함으로써 얻을 수 있는 장점은 많다. 그 중에서 이미 검증된 소프트웨어를 사용함으로써, 오류가 감 소됨에 따라 고품질의 소프트웨어를 생산할 수 있고, 소프트웨어의 개발비용을 생산성을 향 상시킬 수 있다. 본 논문에서는 소프트웨어를 재사용 함으로써 소프트웨어 개발 시에 사용 되는 비용과 생산성을 상대 비교해서, 소프트웨어 개발에 소요되는 비용과 생산성의 관계를 나타내는 새로운 모형과 예를 제시하고 있다. 또한 소프트웨어 재사용시에 개발기관과 총인 월에 대한 생산성을 COCOMO 모형을 사용해 규명하고 있다.

논문의 내용에서는 21세기 초일류 기업을 위한 신경영기법의 종합적 접근방법을 논하고자 하였으며 지속적인 생산성 향상을 추구하는 기업의 생산 시스템을 세계수준급으로까지 발전시키는 비젼성에 관하여 논의하였다. TIFA란 생산성 향상을 위한 방법론이요, 생산방법의 개량이요, 인간을 위한 융통성 있는 생산 시스템이라고 했다. 하지만 그 생산방식에 인간중시, 인가존중의 휴면정신이 외면 당한다면, 그것은 결코 진정한 의미의 TIFA라고 말할 수 없다. TIFA란 생산현장, 산업근로자들의 신념과 긍지까지 현미경적 시각으로 발견, 연구해야 한다는 것이다. 즉, 진정한 TIFA란 생산성 향상을 위한 과학과 기술, 인간과 경영의 하모니로 시작되는 유연하고도 융통성 있는 생산 시스템이라고 정의한다.

This research dealt with author production, subject production, university production, core of the majoring subject production, the multi-authors production, authors majoring in their fields production, languages and periods production for the purpose of clarifying the general research pattern of us by using the method of content analysis of 767 items of monographic which have been published in Korea between 1957 and 1997. This study was done to apprehend the general research pattern of Library and Information Science.

This paper examines the shift to service economy in the developed countries including Korea and analyzes whether Baumol's cost disease hypothesis could explain the labor productivity growth in the developed countries even though the share of service industry is rising rapidly. We have found the following results: First, the shift to service economy is widely observed in the developed countries. Second, the productivity gap between manufacturing and service industry is widening as a result of stagnant productivity growth in service industry. Third, however, the productivity in the whole economy is still growing because of the large productivity differences among the sub-industries in service industry. Fourth, we have found that the productivities of some service industries, such as finance, communication, business service, etc., are almost same or larger than the productivity of manufacturing industry. From this fact it is likely that the productivity of the whole economy could grow in spite of the stagnant productivity growth in service industry.

The relationship between keywords, found in all productivity related papers published in the KSCE journal for last 15 years, were analyzed in order to reveal a research trend in the area using text mining and A-Priori algorithm. As the results, it is found that the word of 'productivity' is most closely related to the words of 'work' and 'labor'. Futhermore, the word is somewhat related to those of 'factor', 'model', simulation', and 'work time'. It is also revealed that, on the other hand, the words of 'machine' and 'equipment' have little relationships with the keyword. This research will be a great help for academia to understand a research trend in the area of construction productivity.

This paper uses MPI (Malmquist Production Index) method to provide basic information and policy direction derived to improve the productivity. This can identify whether or not the railroad service have excellent services, if there are structural problem, in which sector is experiencing a degree of productivity, in which sector should be set targets to some degree. According to the result, the productivity of Korea railway lines is measured 1.1 both publicity and profitability aspects. Changes in production technology were the most important causes. Strategic planning should consider to increase the productivity such as modernization of facilities and equipment, cost savings, and increase in productivity of employee and rail cars.

소프트웨어 개발 프로젝트 사업의 성패는 사업의 첫 관문인 소프트웨어 견적의 결과에 좌우되는 경우가 많다. 특히, 확정가격 계약으로 수행되는 국내의 소프트웨어 사업 관행 하에서는 견적의 잘못이 회사의 존폐로 귀결되는 경우도 있다. 견적의 핵은 정확한 원가의 파악인데, 이를 위해서는 고객이 요구한 업무량과 개발자의 생산성을 정확히 아는 데서 출발해야 한다. 문제는 고객의 요구를 사업 초기에 정확히 파악하는 것이 쉽지 않을 뿐 아니라, 개발자 자신의 생산성을 잘 모른다는 것이다. 더욱이 정보의 부족으로 프로젝트의 특성 파악을 제대로 할 수 없어서, 해당 프로젝트에 적합한 생산성 보정계수의 적용이 어렵다는 점이다. 본 사례는 삼성SDS가 금년도에 종료된 수십 여 개의 프로젝트로부터 수집한 생산성 영향인자들이 생산성에 어떠한 영향을 어느 정도나 미치는 지를 분석한 것이다. 본 분석을 통하여 생산성에 영향을 미치는 주요 인자들을 식별할 수 있었고, 이들이 미치는 영향 정도를 바탕으로 견적에서 활용할 수 있는 다양한 파라메트릭 모델을 만들 수 있었다. 본 논문은 생산성 영향인자의 식별과 이들을 이용한 견적용 파라메트릭 모델의 개발 방법을 다루었다.

In this paper, Improved productivity models of container terminal are provided by utilizing a simulation considering Tandem-lift Quay Crane and transport vehicle of container's high productivity 'Alternative ship-to-yard vehicles.' Feature of this method is deriving the data of tandem-lift Quay Crane and Alternative ship-to-yard vehicles, estimating the productivity model of tandem-lift Quay Crane by using regression analysis. Tandem-lift Quay Crane is equipment of loading and unloading to increase productivity approximately by 2 time existing (single, twin) Quay Crane by dealing with four 20ft containers or two 40ft containers at the same. Alternative ship-to-yard vehicles can transfer containers(4TEU) more than existing Yard Tractor. This paper is deriving the optimal combination showing the highest productivity by using simulation considering Tandem-lift Quay Crane and Alternative ship-to-yard vehicles on container terminals and developing estimating model of productivity by using regression analysis using data of simulation.

The aim of this study was to analyze the productivity changes in government-funded research institutes for Economics & Humanities and Social Sciences. From Malmquist total factor productivity index analysis, the average productivity decreased 6.5% between 2006 and 2010. Further analysis showed that technical efficiency increased 4.7% annually while the technology change rate decreased 10.8% on average. Under pressure for innovation from the outside, research institutes responded to managerial efficiency improvement, which lead to increases in technical efficiency. On the other hand, for productivity improvement of government funded research institutes, they must pursue technological advances by securing an outstanding research workforce, expanding the R&D budget, and changing the R&D method. Each institute must perceive the cause of an individual institute's productivity change, and establish strategies for increasing productivity.
