  • This paper presents a corrective maintenance model to determine either type of maintenance actions upon failure of the system. Types of maintenance actions considered are minimal repair and replacement. Minimal repair cost is assumed to be random, whereas replacement cost is fixed. A policy, B(t), which determines the type of maintenance action based on the estimated minimal repair cost when the system fails at time t is adopted. To obtain an optimal policy, an expected maintenance cost per unit time is derived and is minimized with respect to B(t).

  • Korea has accomplished remarkable economic growth based on the accumulating technological capability. Science and Technology policy aiming at quantitative growth has concentrated on S&T hardware infra-structure construction but it overemphasizes technological factors. This policy has not sufficiently reflected social and cultural elements that should be incorporated in S&T development process. Therefore many experts have been emphasizing the importance of science culture as an important ingredient of S&T policy. This paper aims at investigating how science culture could be diffused. Nowadays, many countries have a strong interest in science shop as an important instrument of science culture. Science shop, however, has been activated in European area so it is not familar to Korea. However there are already a few science shops in Korea. In this paper, we will investigate the Korea science shops. In particular, we will analyze the current status, organizational structure and problems of Korea science shops. we will draw some important policy implications to activate science shops and to strengthen S&T policies in Korea.

  • A block replacement policy using items with different reliability is discussed. We divide system unit failure modes into two modes and use less reliable unit when operating unit fails near the planned preventive replacement time. In this policy, item A has two failure modes. Mode-1 failure is removed by minimal repair, mode-2 failure by replacement. If mode-2 failure of item A happens in (0, $T-{\delta}$), failure item A is replaced by new item A. If mode-2 failure of item A happens in ($T-{\delta}$, T), failure item A is replaced by new item B. Item B should be cheaper and less durable than item A. Under this policy, we determine the preventive replacement interval $T^{*}$ and the interval ${\delta}^{*}$ of item B replacement which minimize the cost rate per unit time.

  • The Office of Science and Technology Innovation (OSTI) was created by a different method of organizational change from that of precedent administrative reforms. According to results of the new method, the OSTI case can be widely applied to other ministries as an alternative model for governmental reform. The theory part introduced two approaches of organizational reform, namely structural approach which focuses on the level of hierarchial authority and process approach which emphasizes the flow of information/expertise in organizational operation. It also discussed various ways of understanding for S&T policy coordination. After this, the paper reviewed details of the OSTI reform with special reference to implications for the mode of S&T policy coordination. It concludes that the OSTI may offer an opportunity to strengthen the coordination mechanism of the process approach.

  • This study examined the evolution of S&T Basic Acts in Korea from the Science and Technology Promotion Act (1967) through the Special Act on STI (1997) to the Framework Act on Science and Technology (2001) in the following aspects: 1) comprehensive plans, 2) coordination mechanisms for S&T policies, 3) enforcement of R&D programs and performance diffusion, 4) promotion of human resources, 5) and S&T investment and budgeting. Before the Framework Act on S&T was enacted in 2001, critical issues were found in establishing S&T master plans, promotion of R&D programs, comprehensive coordination mechanisms, and R&D budgeting. The three Basic Acts have expanded the scope of regulation over time to cover the entire cycle of the S&T process. They concern a wide range of issues, including creating a basis for scientific and technological development, S&T promotion, disseminating and commercializing research outcomes, and preventing adverse effects from science and technology. The content of the Basic Acts has evolved in response to changes in the political, economic, and social environment of Korean industry during the past five decades.

  • This paper investigates the interaction among the paradigm of Low-Carbon Society (LCS) and the megatrends in field of population, environment, geopolitics, and energy. The paradigm of LCS is regarded as a 'social will' trend, distinguished from other 'phenomenal' trends. The qualitative analysis shows that the megatrends and the LCS paradigm have positive/neutral/negative impacts on one another, while some impacts can be reversed to other types of impact with the conditions having ripened. In quantitative analysis, the correlation between the LCS paradigm and the economy is traced with our Integrated Assessment Model, looking into such response options as population control, increase in labor force participation, and productivity enhancement to maintain utility level despite the pursuit of LCS paradigm. The future challenges in national strategy and S&T policy are suggested, based on the interaction analyses.

  • In this paper, we consider the M/G/1 queueing system with randomized control of T-policy. Whenever the busy period ends, the server is turned off and takes multiple vacations whose interval is fixed time T with probability p or stays on and waits for arriving customers with probability 1-p. We introduce the cost function and determine the optimal combination of (p, T) to minimize the average cost per unit time.

  • In the past three decades since the advent of market oriented reforms began in 1978, China has made rapid strides in catalyzing economic growth. The economic development coincides with the development of significant capabilities in several areas of science, technology, and innovation. China has recorded notable achievements in a number of emerging fields. This paper investigates the process that has catalyzed the developments in Science and Technology (S&T) and the key factors that have facilitated this process. The causality of dynamism of S&T in China points at targeted development, an emphasis on high growth industries and high technology, commensurate resource mobilization, ruthless restructuring of innovation actors, dynamic organization and management of R&D, continuously evolving policies with strict enforcement, and implementable instruments. This paper attempts to bring out the roadmap of the Chinese transformation process in S&T and derive policy lessons for India.

  • The study has applied the four stage "Model of State Behavior in Crisis" to trace the post 9/11 crisis foreign policy decision making process in Pakistan. It argues that ominous attacks on the United States by al-Qaeda and subsequent declaration of President Bush to fight against terrorism transformed the global and regional politico-security dimensions at t1 stage. Being a neighboring country, Pakistan's support was inevitable in the war on terror and Washington applied coercive diplomacy to win the cooperation from Islamabad. Consequently, in case of decline to accept American demands, Pakistan perceived threat to basic values/objectives of the country and simultaneous time pressure amplified the psychological stress in decision makers at t2 stage. Therefore, the decisional forum was setup at t3 stage and Pakistan decided to join the United States at t4 stage, which defused the foreign policy crisis.

  • Innovation Policy has evolved to solve social problems through technological innovation. Industrial innovation policy promotes technological innovation so that it consolidates industrial competitiveness and aims at economic growth; however, societal innovation policy promotes technological innovation in the social service domain to improve the quality of life and strengthen sustainability. A different policy regime is required because the objectives and directions of societal innovation policy are different from those of industrial innovation policy. This report consolidates the concepts and characteristics of societal innovation policy that suggest policy options.
