  • In order to evaluate the cost effectiveness of seismic isolation for bridges in low and moderate seismic region, a method of calculation minimum life-cycle cost of seismic-isolated bridges under specific acceleration level and soil condition is developed. Input ground motion is modeled as spectral density function compatible with response spectrum for combination of acceleration coefficient and site coefficient. Failure probability is calculated by spectrum analysis based on random vibration theories to simplify repetitive calculations in the minimization procedure. Ductility of piers and its effects on cost effectiveness are considered by stochastic linearization method. Cost function and cost effectiveness index are defined by taking into consideration the characteristics of seismic isolated bridges. Limit states for calculation of failure probability are defined on superstructure, isolator and pier, respectively. The results of example design and analysis show that seismic isolation is more cost-effective in low and moderate seismic region than in high seismic region.

  • 이 논문은 국내 철도 모의운전연습기의 훈련비용 효율성(TCE; training cost-effectiveness)을 분석하는데 그 목적이 있다. 교육훈련 비용 효율성이란 해당 모의운전연습기를 통해 얻어진 학습 효율성(TER)과 그에 따르는 비용 효율성(TCR)을 모두 고려한 비율이다. TCE가 1보다 작으면 분석하고자 하는 훈련체계나 새롭게 적용하는 훈련 도구의 비용 효율성이 없는 것이고, 1보다 크면 비용 효율성이 있는 것이다. 그러나 훈련체계나 훈련 도구가 비용 효율성이 없다 하더라도 안전과 관련된 사항은 반드시 비용에 관계없이 고려되어야 한다. 본 연구는 국내 철도 모의운전연습기의 훈련비용 효율성을 분석하였으며, 훈련의 종류와 훈련 내용에 따라 적절한 종류의 모의운전연습기를 활용하는 것이 비용 효율성이 있는 것으로 분석되었다.

  • Background : Bojungikgitang(BJT) and Banhabaekchulchonmatang(BBT) are known to treat the tinnitus patients, which were registered Korean National Health Insurance coverage lists. Objective : Few studies have evaluated economic benefits of both herbal medicines. This research is to investigate the cost-effectiveness of Bojungikgitang(BJT) and Banhabaekchulchonmatang(BBT) in chronic tinnitus patients over nineteen years old. Method : We built the decision tree model of chronic tinnitus and executed the deterministic analysis and threshold sensitivity analysis based on randomized clinical trial. Effectiveness was measured in quality-adjusted life-years(QALYs), and costs were in 2009 KRW(South Korean Currency). The perspective is societal, time horizon is 10 weeks, and Korean willingness to pay threshold is assumed to 20,000,000KRW. Results : In the base case analysis, BJT treatment resulted is better outcomes as low cost, so BJT is dominant medicine and BBT is dominated. But both cost per QALYs (BJT is 3,120,339KWN per QALY, BBT is 3,505,780KWN per QALY) are lower than the threshold, that could be covered by Korean National Health Insurance(KNHI). Conclusion : This study results showed that BJT was more cost-effective than BBT treating tinnitus patients for 10 weeks, and the cost per QALYs of both alternatives were lower than Korean national threshold.

  • To determine the cost-effectiveness of converting fish waste into liquid fertilizer, this study analyzed the production of 3 L of liquid fertilizer from the fermentation of fish waste. The total product cost of the fertilizer was calculated to be $165.26 for a one-batch operation. If the seed culture was repeated five times, the total product cost could be reduced to $36.39/L. According to this analysis, the reutilization of fish waste as liquid fertilizer was not particularly economically attractive at present, and plant-scale production would be necessary for commercialization. This is the first cost-effectiveness analysis of the bioconversion of fish waste into liquid fertilizer.

  • 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.

  • Objectives We aimed to examine health-related economic analysis of available interventions on idiopathic short stature (ISS). Methods Eight studies were reviewed from English, Korean, and Chinese databases which were published up to December 24, 2020. Effectiveness, utility, and cost data were extracted from the studies and descriptive analysis of the individual studies was conducted Results Five studies were chosen. In the two economic evaluation studies, the incremental cost-effectiveness ratio (ICER) of growth hormone (GH) treatment was presented by performing cost-effectiveness analysis based on the deterministic decision tree approach for the GH and untreated group. Final adult height and direct medical costs were analyzed as effectiveness and cost outcomes. In 1 review article, an ICER of GH was presented based on systematic review on the effects of the GH treatment. In the two clinical trials, the effectiveness and cost of the 12 months Oriental medicine combination treatment were presented in comparison with the GH treatment alone. There were no literatures that provided utility data of available intervention on ISS. Conclusions The results of this study will be used as basic data for the economic analysis of Oriental medicine treatment on ISS in the future.

  • Background: Related to escalating health care costs and the questionable effectiveness of multiple interventions including lumbar facet joint interventions, cost effectiveness or cost utility analysis has become the cornerstone of evidence-based medicine influencing coverage decisions. Methods: Cost utility of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain was performed utilizing data from a randomized, double-blind, controlled trial with a 2-year follow-up, with direct payment data from 2016. Based on the data from surgical interventions, utilizing the lowest proportion of direct procedural costs of 60%, total cost utility per quality adjusted life year (QALY) was determined by multiplying the derived direct cost at 1.67. Results: Patients in this trial on average received $5.6{\pm}2.6$ procedures over a period of 2 years, with average relief over a period of 2 years of $82.8{\pm}29.6$ weeks with $19{\pm}18.77$ weeks of improvement per procedure. Procedural cost for one-year improvement in quality of life showed USD $2,654.08. Estimated total costs, including indirect costs and drugs with multiplication of direct costs at 1.67, showed a cost of USD $4,432 per QALY. Conclusions: The analysis of therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain shows clinical effectiveness and cost utility at USD $2,654.08 for the direct costs of the procedures, and USD $4,432 for the estimated overall cost per one year of QALY, in chronic persistent low back pain non-responsive to conservative management.
