Design productivity can't be easily measured since there are so many different design productivity factors but such a few meaningful design product units. It's very difficult to evaluate the performance of design activities. Performance measures are not defined easily and are not measured correctly in many cases. So, in this paper the value added productivity is used to measure and analyze design productivity. Some issues are analysed to assess real productivity level of Korean service industry. And then we propose a few ways to Improve design productivity including the use of scientific approach at design processes and the change of the industry structure. It seems that the higher the level of IT(Information Technology) usage at a design industry is, the higher the design productivity is. Further research will be needed to investigate scientific approaches to increase design productivity.

This paper focuses on the relationship between the characteristics of network and the productivity of scientists, which is rarely examined in previous studies. Utilizing a unique dataset from the Korean Citation Index (KCI), we examine the overall characteristics of the research network (e.g. distribution of nodes, density and mean distance), and analyze whether the network centrality is related to the scientific productivity. According to the results, firstly we have found that the collaborative research network of the Korean academics in the field of statistics and computer science is a scale-free network. Secondly, these research networks show a disciplinary difference. The network of statisticians is denser than that of computer scientists. In addition, computer scientists are located in a fragmented network compared to statisticians. Thirdly, with regard to the relationship between the researchers' network position and scientific productivity, a significant relation and their disciplinary difference have been observed. In particular, the degree centrality is the strongest predictor for the scientists' productivity. Based on these findings, some policy implications are put forward.

연구자 개인의 연구 성과를 측정하기 위한 연구는 2005년 Hirsch가 h-지수(index)를 제안하면서 이와 관련된 후속 논의가 매우 활발하게 진행되고 있다. h-지수를 변형시킨 g-지수도 각광을 받고 있다. 하지만 이들 지수의 경우 연구에 기여한 비율에 상관없이 해당 논문의 인용빈도만을 고려하여 지수가 정해진다는데 그 한계가 있다. 본 연구에서는 이 두 가지 지수의 단점을 보완하기 위해 각 지수에 저자의 기여도를 접목시킨 K-지수를 제안하고자 한다.

The performance of scientific researchers has been studied from a number of different aspects, mostly in developed countries. This paper attempted to identify salient factors influencing scientific performance at individual level in a developing country. A model describing the productivity and performance of scientific researchers was developed. Four hypotheses were derived from the model; i) the degree of diversity of a researcher will affect the degree of his scientific performance, ii) the degree of dedication will affect the degree of his performance, iii) the degree of research pressure will affect the degree of his performance, and iv) the degree of satisfaction will affect the degree of his performance. Data were collected through questionnaires responded by 48 researchers from two research organizations. The results of data analysis supported the hypotheses in part. Specifically, diversity measured by the number of research areas was related to the productivity of research reports (p<0.05); research pressure influenced the average number of research papers (p<0.05). The results of hypothesis testing of the satisfaction showed mixed directions according to the indicators. Even though the results of data analysis did not support the hypotheses unanimously, probably due to the limitation of sample size, most of the descriptive analysis indicated that the direction of hypotheses in developed countries seemed to be similar in developing country too. However, more research efforts are needed to verify the research findings of developed countries in developing countries.

This study aims to contribute to the debate over the age-productivity relationships in scientific and technological research. For this purpose, we conducted an empirical experiment employing a time-series cross-section dataset derived from the KRI of the NRF containing data on individual researchers of fifty major universities in Korea covering the period of 2008-2013. This study has found that: (1) there exists an inverse U-shaped age-productivity relationship at the level of individual researchers; (2) the impact of the average age of a research group on the productivity of individual researchers varies across fields; (3) male and female researchers move along different age-productivity curves; and (4) the inverse U-shaped age-productivity relationship also holds at the level of organizations. The results suggest that the aging of researchers in Korea will soon reach the stage where serious losses in research productivity become a reality. Yet, it is not so clear whether the observed decline in the performance of older researchers is due to declining cognitive capability, which is an unavoidable result of aging, or to declining motivation, which results from an institutional system that discourages older researchers' research activities (such as reduced access to research opportunities or mandatory retirement). What is clear is that it is inevitable for the Korean science system to change the current seniority- and age-based organizational system into one of higher adaptability.

In 1926, Alfred Lotka examined the frequency distribution of scientific productivity of chemists and physicists. He observed that the number of persons making n contributions is about $1/ n^2$ of those making one and the proportion of all contributions that make a single contribution is about $60\%$. Investigator studing the applicability of 'Lotka's Law' to Mathematics and to Mechanical engineers have fitted Lotka's Law and concluded that the law applied to these subject fields.

A sustainable development in science, innovation, and technology requires a balanced distribution of scientific wealth in sub-country regions. This paper addresses the issue of geographical distribution of scientific wealth and its goal is to offer a framework to describe and measure the share of provinces in national scientific wealth. Our proposed model divides the indicators of scientific wealth into two groups, production and the use of scientific wealth. To evaluate this model, the scientific wealth of Iran was studied using recorded data on IRANDOC databases. Rich, average, and poor provinces were identified and the results showed that 70% of the scientific wealth belongs to 20% of the provinces. The findings can facilitate planning for a sustainable science and technology policy.

이 연구는 중국 서부지역의 대학을 중심으로 진행되었으며, 2017년부터 2021년까지 12개 대학의 연구수준을 정적 효율성과 동적 효율성을 모두 고려하여 조사하였다. 정적 효율성은 데이터 포락 분석(DEA)을 사용하여 검사하였고, 동적 효율은 Malmquist 모델을 사용하여 분석하였다. 분석결과, 서부12개 대학의 과학연구 효율성은 일반적으로 높지 않았으며 '쌍일류' 건설의 맥락에서 대학의 과학연구 효율성은 증가하는 추세를 보이고 있으며, 과학연구 효율성의 원인으로 최근 몇 년 동안 효율성이 크게 증가하였다. 연구 활동의 TFP (Total Factor Productivity)는 기술진보지수의 영향을 받아 초기에 증가하다가 감소하다가 다시 증가하는 패턴을 보였다. 연구 결론은 서부 대학들의 과학연구 활동을 위해 자원을 합리적으로 배분하여 효과적인 과학연구 메커니즘을 갖추어서, 관리기준을 개선하여야 한다. 이에 과학혁신과 이에 상응하는 성과를 촉진하여, 궁극적으로 중국 서부의 과학기술 수준을 높일 수 있어야 하겠다.

The article describes actions and strategies to obtain higher productivity on maritime automobile terminals. The main focus is on elaboration of efficient and effective organizational structure to model and implement short-term, mid-term and long-term strategies. In addition, with an empiric approach we combined the analyses of current findings in important scientific papers and our acknowledgments in practical research of north Adriatic maritime automobile terminals. The main goal is to propose actions towards increasing system's productivity. Based on our research of the north Adriatic maritime automobile terminals and with Lambert's model an in-deep analysis of limiting factors, user's expectations and possibilities for productivity increase has been performed. Moreover, with our acknowledgments a three-level decision-support model is presented. With an adequate model implementation it is possible to efficiently develop and implement different strategies of productivity measurement and productivity increase, especially in the fields of internal transport productivity, entrance/exit truck gates operations and wagon manipulations. According to our observation a significant increase might be achieved in all three fields.
