The purpose of this article is to examine the cause of policy non-compliance in the case of pharmaceutical rebates from the perspective of rational choice institutionalism. In Korea, there have been rebates practices between pharmaceutical companies and hospitals since the introduction of the Actual Remuneration System for insured medicine in 1999. The government has chosen the policy means of punishment to eliminate pharmaceutical rebates but the illegal practices are still widespread. Institution in rational choice institutionalism usually reflects the incentives and preferences of actors, and the Actual Remuneration System has resulted in a the lack of procedures to ensure savings on drug expenditures. Pharmaceutical rebates are the product of the institutions which reflect their incentives: the Actual Remuneration System, the current pricing policy for generic drugs, the drug distribution system, and so on. In the end, the problem of the rebates is the consequence of policy non-compliance as actors' rational choice because their incentives lead to opportunistic behaviors. We should therefore understand the incentive structure of policy stakeholders, which is derived from the view of new institutionalism; also, the newly designed Korean drug pricing policy reform must be compatible with the incentive structure.

Most recently, the development and publication of the ordinance and the manual of policy qualify management is spreading the recognition of quality Control in the public sector. The purpose of this study is to introduce of the system quality Control for local government's policy. So we suggested lessons drew from case study(Daegu metropolitan city, Gumi city) on current introduction. To introduce the system quality Control for local government, we have to gain the sympathy of introduction, second prepare of inducement, last manage PQM flexibility.

This paper presents a model that considers combinations of rework, repair, replacement and scrapping. Policy-Iteration method of inspection is proposed for a serial manufacturing system whose repair cost, scrap cost and inspection cost. when it fails, can be formulated by Markovian approach. Policy-Iteration stops when new inspection policy is the same as previous inspection policy. A numerial example is presented.

The Bidding System of the public IT project in Korea is fallen behind, because of the ordering habitual practice based old system, overcompetition based sealed bid and subcontract practice. To innovate this old-fashioned practice for public IT project bidding, this paper wants to generate a proper improvement direction of the public IT project contract law and the related policy through the literature review about the ordering and receiving system in Korea, the practical survey about bidding marketplace in Korea, and competition between bidding system and/or policy of major countries: USA, UK, France and Japan. As a result of practical survey, many problems of the current public IT project bidding system came out and improvement ideas toward future situation turned up. These outputs implicate that the current law and system related public IT project demands better improvement work for the future ubiquitous Korea. Therefore, this paper, to solve these problems about bidding systems and practice, propose the new public IT project contract law and the related policy, reflecting these improvement ideas by the practical survey and the literature review, and benchmarking points from bidding system of other countries.

This paper deals with an order picking system in an automated storage and retrieval system(AS/RS). For the order picking system, two fundamental policies, the batching and the picking policies, must be selected. The batching policy determines the manner in which orders are combined for picking in each trip of picking machine. The picking policy determines the sequence of all items in each group of orders. Most of studies for the batching policy doesn't consider dynamic arrivals and due dates of orders. Therefore, we present an batching policy which considers dynamic arrivals and due dates of orders. The presented batching policy is efficient for the automated storage and retrieval system which is connected with a manufacturing system.

It is necessary to evaluate the greenhouse gases (GHGs) reduction policy by central and regional governments to set up the suitable GHG emissions measures. Quantitative, qualitative and synthetic methods have been adopted by previous researches to estimate GHG reduction policy. However, these methods mostly focused on the results of the reduction policy, rather than understanding and fixing the integrated structures of GHG emissions. In this research, System Dynamics(SD) was applied to 1 million green homes program, self-carfree-day system and carbon point program. The results showed that SD analyses could be appliable for the estimation of GHG reduction policy by developing the feedback loops and dynamic simulation model. SD can be consider as a supplementary tool to estimate the GHG reduction policies through the recognition of the structure in complex real system.

This study reviews the new Perspectives of science and technology Policy based on "the innovation system ap-proach" . It examines the theories of innovation and the economic rationale of government intervention of the in-novation system approach and compares them with those of traditional nee-classical approach. It also examines the basic theme of science and technology Policy of "the innovation system approach" It argues that the enhancement of innovating capability, the transformation of innovation system coping with changing technological and econom-ic environments, and the policy learning of the government and innovators are very important and peculiar sub-jects of the science and technology Policy based on "the innovation system approach".ovation system approach".uot;.

This paper studied issues in decision making on the production control policy of a cathode plate manufacturing process in zinc refining plant. The present production system has a long lead time from raw materials (aluminum plate) to products (cathode plate) due to many WIP inventories. Because WIP inventories are stocked at each process and moved from one place to another frequently, they are the main cause of inefficiency in the process. In this paper, to solve this problem, several production control policies have been identified and studied. Several simulation models are used to compare the performances of these production control policies. The output lead time and WIP (Work In Process) of real production system are compared with those of simulation models. PUSH, CONWIP, DBR, KANBAN and CONWIP-DBR models have been used to simulate and review the optimized production control policy that achieves the target output quantities with decreased lead time and WIP. The simulation results of each production control policy show that CONWIP and CONWIP-DBR models are the good production control policy under the present production system. Especially in present production system, CONWIP with one parameter is easier control policy than CONWIP-DBR with two parameters. Therefore CONWIP has been selected as the best optimum production control policy. With CONWIP, lead time has been reduced by 97% (from 6,653 to 187 minute) and WIP has been reduced from 1,488 to 53, compared to the present system.

A system subject to random shocks is considered. The shocks arrive according to a Poisson process and the amount of each shock is exponentially distributed. In this paper, a periodic inspection policy for the system is compared with a random inspection policy. After assigning several maintenance costs to the system, we calculate and compare the long-run average costs per unit time under two policies.
