Current volume reduction methods for wasted expandable polystyrene (EPS) foam are summarized and compared each other. Wasted EPS foam has not been recycled effectively because of its large volume to weight ratio. This has prevented from its proper recycling because of high cost of transportation to recycling plant. Successful recycling of wasted EPS foam results directly from successful, i.e. economically and environmentally, volume reduction of wasted EPS foam. This paper deals with various methods for volume reduction methods of wasted EPS foam. Five typical methods of volume reduction are introduced and they are compared each other in terms of expected PS properties after volume reduction, cost effectiveness of each process, possible effects on environment caused by the volume reduction process, and possible recycled products. The methods include thermal, solvent, far infrared and mechanical compaction. Comparison in this paper is made mostly in qualitative manner. The focus in this study is concentrated on summarizing and comparing existing methods of volume reduction for wasted EPS foam.

This paper was performed for a cost-effectiveness analysis of pharmacologic treatment of hypercholesterolemia. Agents modeled were cholestyramine, gemfibrozil. bezafibrate, lovastatin, pravastatin, simvastatin. Pharmacologic effectiveness was estimated by regression from reported clinical trials. Pharmacologic effects were expressed as the percent change of blood cholesterol level. Cost estimates included patients' travel expenses and time loss as well as resource consumption in the health care sector. Bezafibrate was the most efficient agent for reducing total cholesterol levels, having an cost over 1 year of ￦31.400 per percent reduction in total cholesterol. Simvastatin (10mg/d) was also efficient(￦33,100 per percent reduction). Chole styramine(8g/d) was least efficient at ￦90,200. For low-density lipoprotein cholesterol. simvastatin(10mg/d) was most efficient, at ￦23,200 per percent reduction, followed by lovastatin(20mg/d) at ￦28,000. Gemfibrozil was least efficient at ￦77,800 per percent reduction. For high-density lipoprotein cholesterol. bezafibrate(400mg/d) was most efficient at ￦39,300 per percent increase of high-density lipoprotein cholesterol. Cholestyramine was least efficient at ￦514,700. Analyses combining low-density lipoprotein cholesterol and high-density cholesterol effects suggest that bezafibrate(600mg/d) and simvastatin (10mg/d) were most efficient for reducing cardiovascular risk. The cost-effectiveness analysis results show that both simvastatin and bezafibrate could be efficient treatment. Simvastatin provide more effective treatment at higher cost, whereas bezafibrate is more cost-effective, as it may be less effective, at lower cost. Therefore, clinicians should choose reasonable treatment according to the patient's needs This pharmacoeconimc analysis will provide a guideline for efficient pharmacologic treatment and also be reference data for pricing new drugs.

This paper presents about the analysis on cost factor reduction using the life cycle cost model for motor block in the KTX-1. Until now, most life cycle cost of the system as a whole that has been studied. but in case of railway industry part, LCC studies are needed on the subsystem like a propulsion control system because subsystems are developed continuously localization. Therefore, In this paper presents cost breakdown structure for life cycle cost (LCC) estimation for localization development of propulsion control system (Motor Block) in high speed railway vehicle (KTX-1). Also to analysis LCC on motor block, it was analyzed physical breakdown structure (PBS) and preventive cost on propulsion control system in view of maintenance cost. Based on this, we describe life cycle cost on motor block of KTX-1.

A dynamic system under random disturbance is considered in the study. In order to control the system efficiently, proper reduction of system dimension is indispensible in design stage. The reduction method using component cost analysis in conjunction with stochastic analysis is proposed for the control of a system. System response is obtained in terms of dynamic moment equation via Fokker-Plank-Kolmogorov(F-P-K) equation. The dynamic moment response of the system under random disturbance are reduced by using of deterministic version of component cost analysis. The reduced system via proposed "stochastic component cost analysis" is successfully implemented for dynamic response and shows remarkable control performance effectively utilizing "stochastic controller" in physical time domain.

The purpose of this study was to identify the effect of living cost reduction through social welfare services and programs and to suggest the further ways of saving living cost for low-income households. For the research purpose, low-income household type was divided into three representative groups such as senior household, household with school-aged children, and household with the disabled based on the literature review. Four case households which live in permanent rental apartment in Seoul were selected as research subjects. During March 14~April 10, 2010, each household was interviewed to examine the details of monthly income and expenditure structure and types of welfare services receiving. Although some differences exist among cases, there was a definite living cost reduction effect through welfare services and programs from 12% to 150%. Household with school-aged children required diversified education programs corresponding to the children's age. Meanwhile, households including senior and the disabled indicated the necessity of convenient transportation system.

IPS(Ideal Production System) is a strategic cost management establishing ideal target cost, innovating cost structure and reduction. However, IPS was commonly used in assembly industry acquiring components and using them to assemble vehicles etc. Applying IPS to steel industry is a new try and not easy because cost elements in flow manufacturing are clustered and obfuscated in a complicated way. This paper proposes ICM (Ideal Cost Management) method adaptive to steel industry. One of the biggest advantages is that ICM could classify and categorize costs in detail according to accounts and manufacturing machines. Based on ICM information, steps of extracting and maximizing ideas are followed effectively. From 2013, ICM was applied successfully to POSCO Pohang Steel Works 38 factories.

An experiment was conducted to investigate the nutritional and economic effects of complete replacement of maize with sun-dried cassava (SDC) in the diet of broiler chickens raised from one day of age to seven weeks. The complete replacement of maize by SDC resulted in a 10 percent reduction (p<0.05) in final bodyweights (1.91 vs 1.72 kg); and a 5 percent reduction (p>0.05) in average feed intake (4.01 vs 3.81 kg). Feed efficiency was not affected (p > 0.05). Cost per kilogramme of feed was reduced by nearly 30 percent and cost per kilogramme of bodyweight gain lowered by about 26 percent by using SDC diet. Relative profit return after accounting for cost of feed and cost of day old chick was higher by 11 percent on the SDC diet. It was concluded that despite the reduction in final bodyweight, the attractive economic return obtained from using SDC, a locally produced ingredient, may be justified in place of maize which is imported.
