The purpose of this study was to understand how consumers perceive the costs of couponing by coupon types and to suggest ways in which coupons should be developed to contribute to consumers' welfare. Costs/benefits of coupons as the most close antecedent variable included the following 8 constructs: searching costs, clipping costs, storing costs, extra expenses, substitution costs, pressure of holding, uncomfortable feelings, and regrets. Since it was hypothesized that the cost of couponing differs by coupon type, four coupon-types were examined: homepage coupon, E-mail coupon, DM coupon, and newspaper/magazine coupon. Data for this research were collected through 732 responses to a self-administered survey of consumers who had used all four types of coupons requesting participation from members of Internet survey firm. The conclusions of this research can be summarized as follows: (1) Women preferred off-line coupons but men preferred on-line coupons. In addition, consumers in Seoul were more familiar and satisfied with on-line coupons than consumers in other regions. (2) Among constructs of costs, consumers perceived regrets, pressure of holding, and substitution costs highly. Differently from previous studies, consumers perceived searching costs and clipping costs to be less important than other costs. (3) Storing costs, pressure of holding, and uncomfortable feelings were higher in off-line coupons, whereas clipping costs, extra expenses, and substitution costs were higher in on-line coupons. (4) In general, most constructs of costs in using homepage and newspaper/magazine coupons were higher than those of E-mail and DM coupons. (5) Cost perception was negatively related to coupon satisfaction at coupon, except newspaper/magazine coupon which was the least satisfactory coupon, regardless of costs (6) Consumers were more satisfied with direct-distribution coupons such as E-mail and DM coupons than public-distribution coupons such as homepage and newspaper/magazine coupons.

This study is intended to propose a systematic procedure for the development of the conditional assessment based on the safety of structures and the cost effective performance criteria for designing and upgrading of bridge structures. As a result, a set of cost function models for a life cycle cost analysis of bridge structures is proposed and thus the expected total life cycle costs (ETLCC) including initial (design, testing and construction) costs and direct/indirect damage costs considering repair and replacement costs, human losses and property damage costs, road user costs, and indirect regional economic losses costs. Also, the optimum safety indices are presented based on the expected total cost minimization function using only three parameters of the failure cost to the initial cost (${\tau}$), the extent of increased initial cost by improvement of safety (${\nu}$) and the order of an initial cost function (n). Through the enough numerical invetigations, we can positively conclude that the proposed optimum design procedure for bridge structures based on the ETLCC will lead to more rational, economical and safer design.

Purpose: Research on attracting foreign direct investment (FDI) plays an important role in helping provinces attract more FDI projects. However, with local competition, FDI enterprises also have to consider their investment. This study evaluates the provincial competitiveness to attract FDI in Thai Nguyen province, a province of Vietnam. In which provincial distribution of competitiveness is measured through nine indicators. Research design, data, and methodology: The study collects data (FDI and the provincial competitiveness index) from 2006 to 2020. The study uses Autoregressive Distributed Lag (ARDL) to text the impact of distribution of competitivenes on foreign direct investment. With time-series, the ARDL is suitable for data analysis. Results: The regression results indicate that the competition index of market entry and informal costs negatively impact attracting FDI into the province; The human resource training quality index has a positive effect on FDI. The results show that FDI enterprises pay much attention to business establishment procedures, hidden costs, and quality of human resources in the province. Conclusions: At the same time, in terms of practice, the results of this study, the authors also offer solutions to help improve the ability to attract FDI into Thai Nguyen province. The significant provincial competitiveness indicators should be taken into account for improvement first.

Objective : The aim of this study is to assess the impact of chronic atopic dermatitis (AD) on quality of life (QoL) as well as the economic burden associated with oriental medical treatment on adult patients with chronic AD in Korea. Methods : The EQ-5D health states, existence and duration of AD in the 2007 National Health and Nutrition Examination Survey (NHANES) were used to obtain the study subjects. A questionnaire including the questions on direct medical and direct non-medical costs associated with oriental medical treatment for adult patients with AD was specifically designed. Twenty-nine, members of the Korean Oriental Medical Ophthalmology, Otolaryngology and Dermatology Society (KOMOODS), completed the questionnaires. Results : The incidence of AD was around 3.09% in 2007 NHANES (sample survey, n=2981). Three months and above in duration of disease was 1.35%. The QoL data revealed as follows: 0.932 in non-chronic AD, 0.916 in chronic AD, and 0.908 in non-AD. We also stratified our analysis by age. The QoL data in 40's was statistically significant (P<0.023). But, no significant differences were reported in 20's, 30's, and 50's. The total direct medical costs of oriental medical treatment for AD was about 2,560,717 Won, and total direct non-medical costs was about 605,125 Won in a year. Conclusions : This study might be applied to find the evidence of economic evaluation in oriental medicine for AD. More rigorous studies are warranted.

Objective : To estimate the annual economic costs attributable to cigarette smoking in Korea. Methods : The costs were classified as being direct medical and non-medical costs, indirect costs and others. We focused on those costs related that are incurred in the treatment of selected diseases (cardiovascular diseases, respiratory diseases, and cancers), which have been proven to be caused by smoking. In addition to the basic costs of treatment, the additional amount of costs occurred due to smoking was obtained by computing the population attributable risk (PAR%) caused by smoking. To compute the PAR%, relative risks of smoking to the number of outpatient visits, hospitalizations, and the death were estimated using the Cox proportional hazard model, respectively. Our major data source was the 'Korea Medical Insurance Corporation (KMIC) cohort study,' which was composed of a total of 115,682 male and 67,932 female beneficiaries who had complete records of their smoking histories in the year of 1992. Results : The annual costs that could be attributable to smoking were estimated to be in the range of 2,847,500 million Won to 3,959,100 million Won. The maximum estimate of 3,959,100 million Won includes 233,100 million Won for medical costs, 5,100 million Won for transportation costs, 27,600 million Won for care giver's economic costs, 69,100 million Won in productivity loss, 3,435,000 million Won lost because of premature death, 172,100 million Won in costs resulting from passive smoke inhalation and 17,100 million Won for costs that resulted from fires that were caused by careless smoking. Conclusion : Our study confirms that the magnitude of the economic burden of smoking to Korean society is substantial. Therefore, this study provides strong evidence that there is a strong need for a national policy of tobacco control in Korea.

This study was conducted to identify the health care utilization, health care costs, and potential health care demands of the disabled in the Medicaid Aid beneficiaries. This study focused on the heath care costs not included in the medical aid allowance such as transportation, informal nursing costs, and ambulatory aids etc. Participants were the 864 subjects who were beneficiaries of the National Medical Aid program living in 10 district of Korea. A questionnaires were distributed to the disabled in the Medical Aid beneficiaries during August to September, 2001 through public offices. Data were collected through a home visiting by social workers working in public offices. Direct and indirect medical costs expended for one month by the participating disabled were examined. They expended 110.748 won $({\$}100)$ for heath care costs, which was not included in the medical aid allowance during the month. The disabled with cerebral diseases or who have level 4 disability expended more health care costs compare to those with other diseases. Gradual expansion of medical aid allowance for the disabled is recommended to alleviate economic burden of the disabled and their family.

This study quantitatively derived the direct socio-economic effects of the Gyeongbu Expressway, which opened in 1970, and suggested a methodological approach for more reliable results. The scenario was set when the Gyeongbu Expressway was not constructed in 1970, the opening of the Gyeongbu Expressway was delayed by 10 years, and the toll road between Seoul and Daejeon, or between Seoul and Gangneung was opened instead of the Gyeongbu Expressway as suggested by the World Bank. In addition, direct benefits were estimated by calculating and comparing the current vehicle operating costs, travel time costs, traffic accident costs, and environmental pollution costs. As a result, it was estimated that about 351 trillion won in direct benefits occurred, and it can be seen that the promotion of the construction project of the Gyeongbu Expressway at that time had a huge impact on South Korea's social economy.

This study is about the suggestion of reduction method for social insurance cost of startup SMEs Based on the study abroad and the current status of Korea we suggest several methods such as direct and indirect support, exemption, deferment/loan. For the economic effect analysis, we derived benefits and costs. Employment, value added, and revenue increasing effects are considered as benefits. Costs are analyzed by each method. In case of exemption, the analysis is impossible. Analysis results show that direct and deferment/loan case have an effect of 563,469 jobs creation, added value of 26.82 trillion wons, and increase in tax revenues about 82.4 billion wons. In case of exemption, There are 105,368 jobs creation, 5.02 trillion wons of added value, and 15.4 billion wons of increase in tax revenues. And for each case, there are costs 9.58 trillion won, 5.42 trillion won, 1.79 trillion won.

Purpose: This analysis was conducted to evaluate the cost-effectiveness of gemcitabine-cisplatin chemotherapy for non small-cell lung cancer patients in an outpatient setting compared with the traditional inpatient setting. Methods: A cost-effective analysis was conducted from a societal perspective. The effects of treatment, which was measured as an adverse event rate, were abstracted from a published literature search and empirical data from one university hospital. The costs included both direct and indirect costs. Direct costs included hospitalizations, outpatient visits, and lab tests. Pharmaceutical costs were excluded in analysis because they were same for both options. Indirect costs included productivity loss of patients as well as care-givers. In order to determine the robustness of the results, sensitivity analysis on treatment protocol was conducted. Results: Literature search showed no difference in adverse effect rates between inpatient treatment protocol and outpatient treatment protocol. Therefore, this analysis is a cost-minimization analysis. Cost-savings in the outpatient setting was 555,936 won for one treatment cycle. Our sensitivity analysis indicated that the outpatient chemotherapy still showed cost-savings, regardless of changes in treatment protocol. Conclusion: The outpatient gemcitabine-cisplatin chemotherapy for non small-cell lung cancer resulted in cost savings compared to inpatient chemotherapy. More importantly, outpatient chemotherapy could improve the utilization of health service resources in terms of available beds.

This paper addresses the analysis of interruption costs and the studies made through the direct interview with Korean Industrial customers for the period of two years. It is conducted to evaluate the direct and short duration interruption costs resulting from local random electrical supply interruptions. The cost is evaluated by providing a designed questionnaire focused on the experience or the preparative actions which consumers predicted they would take. In the first phase, authors made a survey on all types of industry with 176 industrial customers and evaluated them as per standard industry classification (SIC). In that case, the evaluation data obtained are not so reasonable, because the number of sampled industries was small and the sampled industries were surveyed by being divided into 18 types. So, in the second phase the authors concentrated on only 4 types of 302 industries who have many and large sensitive loads to the short duration interruption.
