  • In the last year, the number of registered vehicles in Korea surpassed the 15 million mark, and increase in number continuously. Nowdays, this tendency has raised some problems inevitably in the view of expansion of ELV(End of Life Vehicles) and earth environment pollution resulted from it. A foreign country is strengthening law about a car recycling for to solve this problem. Car recycling technology in Japan was introduced in this paper.

  • The most general treatment method of municipal solid waste is a landfill. The LFG (landfill gas) migration is a serious problem in environmental aspect. The object of this study is to present the possibility of LFG utilization as a replacement or supplementary fuel for local energy -demand. We have developed the EXCEL program for the economic analysis.

  • The ACF(Anisotropic Conductive Film) is used for bonding Drive IC and OLED display device panel. If ACF bonding process is problem, a malfunction of line defect can occur. Because electric resistance increase between the panel and drive IC after a period of time, drive IC can not supply enough current to the panel. This paper is studied on a method of test for line defect.

  • This paper deals with the problem of determining the buyer's economic lot sizing policy for exponentially deteriorating products under trade credit. It is also assumed that the ordering cost consists of a fixed set-up cost and a freight cost, where the freight cost has a quantity discount offered due to the economies of scale. We formulate the mathematical model and the solution algorithm is developed based on the properties of an optimal solution.

  • This paper deals with the problem of determining the buyer's economic lot sizing policy for exponentially deteriorating products under trade credit. Assuming that the supplier's credit terms are already known and the length of delay is a function of the buyer's order size, we formulate the mathematical model and the solution algorithm is developed based on the properties of an optimal solution.

  • It is argued that conventional behavior of government, industry, and the public in managing the seas is dysfunctional and must change. Industry manipulation of government regulatory processes, the public complacency that allows it, and its consequences are discussed. Resolving this problem will reqire industry to embrace a code of environmental ideals such as the Coalition for Environmentally Responsible Economies(CERES) principles. A new emerging 'corporate environmentalism' is discussed.
