산업클러스터는 원래 소규모 지역범위에서 기업, 대학, 연구소 등이 밀접한 네트워킹을 가지면서 집적의 경제를 발생시키는 곳이라는 개념으로 시작되었다. 그러나 최근에는 행정구역을 초월한 협력 또는 클러스터간의 협력이 이루어지면서 광역클러스터의 개념이 등장하게 되었으며, 이를 육성하기 위한 정책수단이 마련되기에 이르렀다. 이 연구에서는 광역클러스터 개념 도입의 필요성을 지리적 범위의 유연성, 기능의 상호보완가능성 및 지역간 협력, 비용절감 및 생산성 확대의 효율성, 클러스터의 발전단계의 각 측면에서 살펴보고, 광역클러스터의 개념을 어떻게 정립하고 한국적 맥락에서 광역클러스터 정책을 어떻게 적용할 것인지를 논의한다.

This paper proposes age replacement policy in stepdown warranty policy. The replacement policy is considered in case of minimally repairable items. And renewal theory is used in analyzing warranty costs. The expected cost per unit time is presented in stepdown warranty policy, free replacement, prorata and hybrid policy. In this article it is assumed that item is replaced at the age of T but the any failure is minimally repaired before the age T. At this point the expected cost per unit time is shown in customer's view point. And numerical example is explored in weibull time-to-failure distribution.

As the industrial paradigm shift, often condensed as the "4th Industrial Revolution," gains momentum, there is a growing need to actively introduce digital healthcare into the medical field. The new administration announced its commitment to become a global leader in the biohealth and digital healthcare sector. To fulfill this pledge, preemptive policy leadership and attention from the government are required. The recent issue of legislating non-face-to-face medical care suggests that introducing digital healthcare goes beyond simply adopting new technologies. Incorporating digital healthcare involves changing the existing healthcare delivery process and coordinating the roles of stakeholders. To successfully change the structure of the medical industry, a mid- to long-term roadmap should be meticulously organized and promoted. Policy efforts are needed to resolve conflicts and lead to compromises through continuous communication with interest groups.

Instead of using the expected unfinished work, we use the expected number of customers in the system for finding the optimal D-policy for the M/G/1 queue in order to make it consistent with other control policies such as N-policy and T-policy.

참여정부 이후에 명시적 및 암묵적 형태의 다양한 클러스터 정책들이 추진되어 왔으나, 산업집적지 경쟁력의 근본적 강화를 위해서 기존과는 다른 새로운 정책적 대안을 모색해야 한다는 의견들이 제기되고 있다. 본 연구에서는 최근 들어 대안적인 지역산업정책 도구로서 활발히 논의되고 있는 스마트전문화 전략과 트리플헬릭스 혁신체계 이론이 기존의 클러스터 정책과 어떠한 이론적 및 정책적 연계성을 가지고 있으며 대안적 클러스터 정책 수립을 위해 어떠한 함의를 제공하는 지에 대해 논의하였다. 이를 통해, 대안적 클러스터 정책은 지역특수성에 토대를 두고 산 학 관의 자발적 협력에 기초한 혁신의 합의공간(consensus space) 구축을 통해 추진되어야 하며, 지역 대학의 경쟁력 강화와 실질적인 산학협력 활성화를 위한 체계적이고 집중적인 투자와 집적지의 관련 다각화 기반을 활용한 신산업의 육성에 초점을 둘 필요가 있음을 강조한다.

This paper studies the two supplier inventory system in which order-level inventory policy with constant leadtimes is adopted. An optimal ordering policy to achieve the expected minimum total inventory cost is found by utilizing the concepts of the equivalence relation. Sensitivity analysis of the system parameters, the replenishment cost and the unit price, is done through a numerical example.

This article is concerned with cost analysis in warranty policy. The warranty cost can be different according to warranty rate and warranty renewal policy. In this paper the stepdown warranty policy is analyzed. Assuming the nonrepairable item, manufacturer's cost is calculated in stepdown warranty policy and free replacement, pro-rata, hybrid policy. Numerical examples are given over Weibull time-to-failure distribution.

The estimate on volatility of stock price is related with optimum of portfolio and Important for allocation of capital asset. If the volatility of stock price is varied according to macroeconomic variables on monetary policy and industrial production, it will assist capital asset to allocate. This paper is related with stock market volatilities on macroeconomic variables in U.S. and Europe, Korea. And, it Is pertain to vary in time of this variables. Thus, this paper is related with volatilities of monetary and physical macroeconomic variables on basis of statistics. And, it is ranged front capital investment to portfolio allocation. Also, this paper takes out of sample forecast and study more after this. In case Germany, France, Italy and the Netherlands, the relative importance of monetary policy and Industrial production Is different from these countries. In case Italy and the Netherlands, monetary policy is primary factor at stabilizing for volatility of stock price. In case Korea, increasing monetary policy and industrial production is positively affected stock market. It is that the positive effect of stock price is caused by mollifying monetary policy and economic growth. Specially, this conclusion is similar to US. In Korea, gradual increase in monetary and industrial production is necessary to stability of stock market. It is different to previous results on basis of increasing stock price of money in long period.
