Purpose: This study was conducted to verify the effectiveness of a cost management education program, focusing on the differences between a web-based group and a mobile-based group. Method: This was a quasi-experimental study using a two-group pretest-posttest design. Participants were 74 nurses in a web-based group and 69 nurses in a mobile-based group. Data were collected between January 2 and February 10. The cost management education program was configured such that the participants studied eight modules over four weeks. The after-program post-test was conducted for one week. Results: Both the web-based group and the mobile-based group showed significantly higher values for cost management knowledge (S=5.98, p<.001 and S=2.76, p=.006, respectively). The web-based group had statistically significantly higher values for cost management knowledge (S=4,461.50, p<.001) than the mobile group. Conclusion: The cost management education program showed improvement in knowledge in both the web-based and mobile-based groups; however, the web-based approach was more effective for nurses. A cost management education program which can be implemented effectively across all range of nurses is recommended.

Background: Cervical cancer, which is common in developing countries, is also a major health issue in Korea. Our aim was to evaluate the cost-effectiveness of Korea's National Cancer Screening Program (NCSP), implemented in 1999. Materials and Methods: The target population was Korean women 30 years or over who were invited to take part in the NCSP in 2002-2007. By merging NCSP records with Korean Central Cancer Registry data, patients diagnosed with cervical cancer who had been screened were assigned to a "screened group," while patients diagnosed elsewhere were assigned to a "non-screened group." Clinical outcomes were measured in terms of life-years saved (LYS), derived from 5-year mortality rates supplied by the Korean National Health Insurance Corporation and National Statistical Office. Direct and travel costs associated with screening were evaluated from the perspective of the payer, the NCSP. Results: A diagnosis via screening was associated with 2.30 LYS, and the incremental cost-effectiveness ratio (ICER) estimate for screening was 7,581,679 KW/LYS (6,727 USD/LYS). ICER estimates were lower for older patients (${\geq}$ 50 years) than younger patients (4,047,033 KW/LYS vs 5,680,793 KW/LYS). The proportion of early-stage cancers detected was 16.3% higher in the screened group. Conclusions: In light of Korea's per capita gross domestic product (32,272 USD in 2012), the current NCSP's incremental cost per LYS appears acceptable.

This paper studied safety benefit of operation-effectiveness analysis on marine traffic safety facilities. In the operation-effectiveness of marine traffic safety facilities the benefits can be divided as safety benefit, transport benefit, and other benefit. Safety benefit was produced as the loss aversion cost of marine traffic caused by the reduction of marine accidents after establishing and operating marine traffic safety facilities. First of all the reduction rate marine accidents was estimated to do it, and the detail model of loss aversion cost was constructed Then each variable in the model was defined and the method of computation presented.

In the era of the 4th Industrial Revolution, the importance of information protection is increasing day by day with the advent of the 'hyper-connection society', and related government financial investment is also increasing. The source of the government's fiscal investment projects is taxpayers' money. Therefore, the government needs to evaluate the effectiveness and feasibility of the project by comparing the public benefits created by the financial investment projects with the costs required for it. At present, preliminary feasibility study system which evaluates the feasibility of government financial investment projects in Korea has been implemented since 1994, but most of them have been actively carried out only in some fields such as large SOC projects. In this study, we discuss the feasibility evaluation of public projects for the purpose of information security. we introduce the case study of the personal information protection program of Korean public institutions and propose a cost-effectiveness analysis method that can be applied to the feasibility study of the information protection field. Finally, we presented the feasibility study and criteria applicable in the field of information security.

The fuel cost of fishing lights for squid jigging fishing vessels takes about 30% of total fishing costs and over 65% of total fuel costs, which indicates the necessity of development of cost-reducing and high efficient fishing light system. This study aimed to analyze the economic effectiveness of LED fishing light systems in combination with metal halide lamp for the squid jigging fishery. Analytical results showed that the level of fishing profits of vessels using LED lights could be different with those of vessels using metal halide lights. That is, when a fuel cost could be reduced by 30%, fishing profits of vessels using LED lights might be the same as those of vessels using metal halide lights, and fishing profits of vessels using LED lights could be higher than those of vessels using metal halide lights when a fuel cost could be reduced by 50%.

Objectives: Overactive bladder(OAB), defined as 'urgency, with or without urge incontinence, usually with frequency and nocturia', is a major burden for patients and impairs quality of life. The aim of this study is to evaluate the cost-effectiveness of antimuscarinic agents for the treatment of overactive bladder including quality of life in societal perspective. Methods: A decision-analysis model was developed to compare the cost-effectiveness of solifenacin and tolterodine IR over 12 weeks. We used data from the published literature to develop the framework for the model. Resource utilization and costs were calculated with public institutional data and supplemented this information with clinical expert opinion, where necessary. Results: The expected costs per patient for solifenacin were 48,762 KRW less expensive than tolterodine IR over 12 weeks. Also, all outcomes including quality of life for solifenacin were more effective than tolterodine IR over 12 weeks. In conclusion, solifenacin dominates tolterodine IR and appears to be cost-effective options for the management of overactive bladder.

This study presents a life-cycle cost (LCC) effectiveness of a concrete with lightweight aggregate. A number of researchers have made their efforts to develop a lightweight concrete, since it is difficult to apply conventional concrete using general aggregate to heavy self-weight structures such as long span bridges. In this study, an optimum design for minimizing the life-cycle cost of concrete slab bridges is performed to evaluate the life cycle cost effectiveness of the lightweight concrete relative to conventional one from the standpoint of the value engineering. The data of physical properties for new concrete can be obtained from basic experimental researches. The material properties of conventional one are acquired by various reports. This study presents a LCC effectiveness of newly developed concrete, which is made by artificial lightweight aggregate. A number of researchers have made their efforts to develop a lightweight concrete, since it is difficult to apply conventional concrete using general aggregate to heavy self-weight structures such as long span bridges. From the results of the numerical investigation, it may be positively stated that the new concrete lead to, the longer span length, the more economical slab bridges compared with structures using general concrete.

Korean government has executed some programs to support producers and/or exporters for the promotion of agro-food exportation. Especially, governmental subsidizing program about the distribution cost for agro-food exportation shows positive effects. However, this subsidy should be changed or partly abolished due to the low effectiveness of subsidy. The goal of this paper is to analyze the effectiveness of governmental subsidy and to present the agro-food products with the low effects of subsidizing program. As the results of analysis, the subsidy for several products, including Ginseng drinks, Paprika, and Chrysanthemum, might be considered to be stopped due to low effectiveness.

The goal of this study is to determine which is the better bomb; a general purpose bomb or a special bomb, from the point of view of cost-effectiveness of air munitions. What we call the special bomb is a laser guided bomb which adds a guidance control unit on the head of a general purpose bomb. Althrough their characteristics of explosion are the same, their effectivenesses are very defferent due to their probability of hitting the targets. Now, in order to measure their relative a effectiveness, we could select various enemy targets such as runway, radar, and then Ive could also calculate requirments of both bombs and firghter aircraft sorties according to the desired damage level of each target, Following above steps, we can derive the total costs and compare effectiveness. As a results of this study, when the attrition rate of aircraft is under $1.1\%$, the general purpose bomb is better than the laser guided bomb. Above $1.1\%$ attrition rate, we could say that luser guided bomb is the most economical bomb.
