The main objective of this study is to develop a model which describe and explain R&D productivity (Researchitivity measured by patents) in Korea four manufacturing industries-electric & electronic, machine, textile, industrial chemicals-during the last ten years. The model largely focuses on the variables related to R&D investment in order to investigate the efficiency of R&D. The results suggest that there is associated with a significant positive correlation between Researchitivity and industrial size. There are interaction effects between the Researchitivity and the sales volume. Researchitivity is positively correlated with the average wage of R&D employees. It also founded that Researchitivity is more closely associated with investment size than industrial nature.

Continuous production of fructo-oligosaccharides employing a packed bed reactor charged with immobilized cells of Aureobasidium pullulans was investigated. The optimum conditions for reactor operation were a feed concentration of 860 g/l; a feed rate, expressed as superficial space velocity of $0.2\;h^{-1}$, and a temperature of $50^\circ{C}$. Under these optimum conditions, the productivity of the reactor was $180\;g/l\cdot{h}$. Initial activity was maintained for more than 100 days. The reactor was successfully scaled up to a production scale of 1000l.

National R&D programs play an important role in the development of a country in this age of the knowledge economy. Since many numbers of R&D programs compete for limited resources such as national R&D budget, the R&D program evaluation problem is a challenging decision-making problem faced by decision makers that deal with R&D management. In this sense, DEA(Data Envelopment Analysis) has been regarded as one of the most widely accepted methods to measure the relative efficiency of productivity of R&D programs. DEA is a methodology to measure and to evaluate the relative efficiency of a homogeneous set of decision-making units(DMUs) in a process which uses multiple inputs to produce multiple outputs. However, the sample of the R&D programs could consist of two or more naturally occurring subsets, thus exhibiting clear signs of heterogeneity such as different objectives. In such situations, the fairness of DEA is limited, for the nature of the relative efficiency of a DMU is likely to be influenced by its membership in a particular subset of the sample. In this study, we propose a methodology AI-DEA(attainment index DEA) allowing for reflecting decision maker's subjective judgement on difference among different subsets of R&D programs which have heterogeneous objectives. This methodology combines AHP and Delphi in order to decide the attainmnet index of each DMU for each outputs, and apply them to DEA model. We illustrate the proposed approach with a pilot evaluation of 13 programs involving 6 different subsets of Korean National R&D programs and compares the results of the original DEA model and AI-DEA model.

본 논문은 세계화가 우리나라 제조업 사업체의 성장과 양극화에 미친 영향을 살펴본 것이다. 본 논문은 먼저 이론적으로 세계화가 성장 및 양극화에 미치는 영향 및 그 구체적 메커니즘을 최근 이질적 기업의 무역이론들을 중심으로 논의하고, 나아가 관련 실증적 증거들이 존재하는지를 살펴보았다. 이를 통하여 본 논문은 세계화가 1990년대 이후 우리나라 제조업 사업체의 생산성 향상뿐 아니라 기업 간 생산성 및 숙련도별 임금 양극화 모두를 초래한 공통적 원인으로 작용하였음을 보여주었다. 본 연구는 최근 세계화된 경제환경하에서 왜 극소수의 대기업만이 특출한 성과를 나타내고 있는지를 이해하는 데 도움이 된다. 마지막으로 본 연구는 세계화의 부작용을 줄이고 그 편익을 보다 많은 기업들이 누릴 수 있도록 하기 위한 정책방향을 제시한다.

Purpose: The purpose of this study was to design of a probabilistic model for optimum manpower planning in R&D department by Montecarlo simulation. Methods: We investigate the process and the requirement of manpower planning and scheduling in R&D department. The empirical distributions of necessary time and manpower for R&D projects are developed. From the empirical distributions, we can estimate a probability distribution of optimum manpower in R&D department. A simulation method of estimating the probability distribution of optimum manpower is considered. It is a useful tool for obtaining the sum, the variance and other statistics of the distributions. Results: The real industry cases are given and the properties of the model are investigated by Montecarlo Simulation. we apply the model to the research laboratory of the global company, and investigate and compensate the weak points of the model. Conclusion: The proposed model provides various and correct information such as average, variance, percentile, minimum, maximum and so on. A decision maker of a company can easily develop the future plan and the task of researchers may be allocated properly. we expect that the productivity can be improved by this study. The results of this study can be also applied to other areas including shipbuilding, construction, and consulting areas.

각국의 과학기술연구개발 투자는 자연의 법칙 규명과 진리탐구에서 벗어나 국가발전의 핵심적인 경쟁력확보 및 삶의 질 향상을 목적으로 하고 있다. 이러한 국가경쟁력을 확보하기 위해서 국가가 시행하는 여러 정책 중에서 정부의 막대한 예산이 투입되는 국가연구개발사업은 사회에 미치는 여러 가지 파급효과를 고려해 보았을 때 중요한 위치를 차지하고 있다. 연구관리 전문기관은 국민의 세금으로 조성된 정부 R&D 정부예산을 정부를 대신하여 연구기획 관리 평가의 공적기능을 민간조직의 형태로 추진하는 점에서 볼 때 준공공부문에 해당하는 특성을 가지고 있다. 정부 R&D 투자의 중요한 주체로서의 연구관리 전문기관의 그 역할의 중요성에도 불구하고, 부처 중심의 정부연구개발예산 편성으로 인해 그 중요성이 간과되어 왔다. 각 부처에 산재해 있는 연구관리 전문기관에 대한 국가적 차원의 현황 파악과 이를 바탕으로 한 이론적 논의가 본격적으로 다루어진 선행연구가 부족하여 관련 정책을 수립하고 시행하는데 많은 어려움이 노정되고 있다. 이에 연구관리 전문기관의 현황파악을 통하여 현상을 분석하고 개념적 특성을 도출하여 유형화를 시도하였다.

The efficient Erythropoietin(EPO)-expression system in mammalian cells is required for massive production for therapeutic use. Ammonium ion is a major problem in the production of useful proteins by cultured animal cells and therefore it is of importance to devise a system by which a high productivity of human therapeutic recombinant protein can be maintained or enhanced under low ammonium concentration.

Strengthening of R & D components of sericulture in India since the sixties has led to a quantum jump in silk production and presently India is the second largest producer in the world. This achievement is primarily due to a number of breakthroughs in R & D to match the requirements of tropics, by way of introduction of improved mulberry varieties and silkworm breeds, better mulberry cultivation and rearing management practices suited to tropical conditions. Of late, new approaches in molecular biology and biotechnology have also been vigorously pursued to strengthen the current conventional strategies. The present paper attempts to provide an overview of the present status of silk production in both mulberry and non-mulberry sectors, breakthroughs achieved through new approaches of biotechnology and the future prospects for maximizing silk productivity in India.
