  • This paper is to study the simulation model of depot maintenance system that analyzes logistics supportability such as component availability and cost of target equipment. A depot maintenance system could repair or maintain multiple components simultaneously. The key performance indicators of this system are component availability, repair cycle time, and maintenance cost. The simulation model is based on the engine maintenance process of army aviation depot. This study combines the NOLH(Nearly Orthogonal Latin Hypercube) experimental design method, to composes 33 scenarios, with a multiple regression analysis to find out major factors that influence on key performance indicators. This study is significant in providing a cost-effectiveness analysis on depot maintenance system that is capable of maintaining multiple components at the same time.

  • The share rate of bus mode has been decreasing continuously. To solve this problem, the local governments implement Bus Management System(BMS) or Bus Impormation System(BIS). In operating the public transportation preferential policy, it is very important to verify the effectiveness of the projects. This study performed the effectiveness of BMS through before and after study based on the field data. Moreover, this study analyzed the factors affecting to BMS. We anticipate that the results of this study would be useful reference in local government's BMS planning.

  • The current contract awarding process regulated by laws and ordinances is analyzed and more reasonable processes are suggested. To this end, the principle of economic analysis is described with emphasis on the cost-effectiveness analysis, and the laws and ordinances regulating the process are thoroughly examined. The current contract awarding rule is based on the weighted sum of effectiveness score and cost score. This may not conform to the framework of economic analysis where effectiveness is supposed to be measured as an output and cost measured as an input. An improvement is attempted to the defense acquisition system and it is recognized that the economic analysis and policy consideration should be performed separately. Concept of statistical testing is introduced to see if the results of the cost effectiveness analyses show the significant difference between the alternatives. It is suggested that the contract awarding process can be improved by performing significance test followed by the aggregation of the two analyses. A minor improvement is also suggested on the application of current rules.

  • Objectives: Objectives: The objective of this study is to describe the WHO-CHOICE(World Health Organization- CHOosing Interventions that are Cost-Effective) programme, and to consider the application of WHO-CHOICE programme in Korea, especially on the health promotion policy. Methods: Literature review was conducted on the contents of WHO-CHOICE programme in the previous studies, guidebook, and software. We also contacted WHO-CHOICE team at WHO to identify the contents not clearly presented in the documents. Results: The WHO-CHOICE programme is a standardized tool for analyzing and comparing the cost effectiveness of health promotion policies. It is composed of PopMod to measure the health effect of intervention and of CostIt to measure the cost. The cost of tobacco control policy in Korea was analyzed with the cooperation of WHO-CHOICE team preliminary, and the results were different with the results of tobacco control policy on western pacific region of WHO. Conclusions: The cost effectiveness study based on WHO-CHOICE programme could help decide a priority of health promotion policy for settings with limited resources. For the improvement of health, the future work on WHO-CHOICE programme need to be considered.

  • This paper presents a control effectiveness analysis of the hawkmoth Manduca sexta. A multibody dynamic model of the insect that considers the time-varying inertia of two flapping wings is established, based on measurement data from the real hawkmoth. A six-degree-of-freedom (6-DOF) multibody flight dynamics simulation environment is used to analyze the effectiveness of the control variables defined in a wing kinematics function. The aerodynamics from complex wing flapping motions is estimated by a blade element approach, including translational and rotational force coefficients derived from relevant experimental studies. Control characteristics of flight dynamics with respect to the changes of three angular degrees of freedom (stroke positional, feathering, and deviation angle) of the wing kinematics are investigated. Results show that the symmetric (asymmetric) wing kinematics change of each wing only affects the longitudinal (lateral) flight forces and moments, which implies that the longitudinal and lateral flight controls are decoupled. However, there are coupling effects within each plane of motion. In the longitudinal plane, pitch and forward/backward motion controls are coupled; in the lateral plane, roll and side-translation motion controls are coupled.

  • This paper describes the results of a cost-effectiveness analysis on the usage of foreign scientific and technical journals. In this study, the measure of cost-effectiveness chosen is the Cost Per Use(CPU) of a journal article. The photocopy usage data and annual subscription costs of journals subscribed by Korea Institute of Science & Technology Information were used. The results of this study illustrate that distribution of subscription cost and photocopy usage, Cost Per Use(CPU) of each journal, CPU of each subject field, etc. 80 percent of the demand for the journal was met by 40 percent of total subscription cost. A relationship was found between subscription cost and photocopy usage, however, no relationship was found between subscription cost and CPU.

  • The coastal and offshore fishery to manage from a fishery permit system in our country at present seems to be a sign of lots problem, which are illegal fishing, a permit rent, non fishing vessel the purpose of vessel reduction, fishery compensation, tax exemption oil, the excessive occurrence of administrative cost due to differences during a period of a fishery permit. All the readjustment system for the permit has suggested an effective solution for a fishery permit management, the maintenance of a fishery order(the prevention of illegal fishery), the prevention of unused fishery, the entrance of new vessel in coastal fishery and it's system has prevent this problems in ahead. This paper has estimated an prevention convenience for an illegal spill of the tax exemption oil, actual effects of vessel reduction, the conservation of fishery resource for the future value and carried out an economic analysis to estimate compliance cost for the system introduction. Also, this study have analyzed throughly the coastal fishery situation and catched lots of issues on the management for the permit system. Especially, the problems improving the readjustment introduction for the permit have estimated the social and economic effects quantitatively and qualitatively with a calculated technique to classify various scenarios. This paper has judged correctly the term of validity for the permit to shorten as a result of the estimation and it will be to take the net convenience cost 1,655thousand million won. The results of this study have expect to provide a basic data to introduce the readjustment system for the permit.

  • 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.
