Investment in health through an array of public health policies will lead to improvement of health at all levels, and the improved health can reduce the socioeconomic costs incurred with diseases. And finally, with reduced healthcare costs associated with diseases and health problems, economy will be able to achieve economic growth and development. Using simultaneous equations model, this study aims to identify this possible channel from public health policies to economic growth. Specifically, the policy effect is investigated on a basis of main disease groups and aging groups. The public health policies are proved to reduce healthcare costs related with disease groups including respiratory, digestive, circulative, and infectious disease, and with all age groups except 20~39 group. And the reduced healthcare costs have shown to increase the real gross domestic products in those group above.

This study analyzed the recognition types of the economic burden for cancer treatment and the characteristics of each recognition type by employing Q methodology. For this study, we determined the final 45 Q statements by conducting literature surveys, internet searches and in-depth interviews. The P samples are 35 people of cancer patients, their family members, and experts. The Q statements were classified according to the forced normal distribution method and the collected data was analyzed using the PC QUANL program. For the analysis results, we extracted four recognition types on the economic burden of cancer treatment, and we named them 'uncertain anxiety', 'acceptance by family burden', 'object to challenge with active response' and 'insurance preparation', depending on their characteristics. The results of this study can be used as a basis for preparing the clinical intervention plan and the policies for cancer patients and the families involved in the fields of medicine, nursing and social welfare.

우리나라는 물의 재이용 촉진 및 지원에 관한 법률에 따라 수자원의 지속 가능한 이용을 목적으로 빗물이용시설의 설치 및 운영을 법·제도적으로 의무화하고 있으며, 위 법에 근거하여 지방자치단체에서는 빗물이용시설의 설치를 장려하기 위한 재정 지원 정책을 시행하고 있다. 환경 투자사업의 일환인 빗물이용시설 설치 사업은 장기간에 대한 경제성 분석이 요구되며, 분석에 이용된 경제성 분석 방법 및 사회적 할인율에 따라 분석 결과가 상이할 수 있다. 이에 따라, 이 연구에서는 순현재가치와 편익-비용 비율을 비교·검토하여 빗물이용시설의 경제성 분석에 적합한 방법을 제시하였으며, 경제성 분석에서 불확실한 요소인 사회적 할인율과 물가상승률에 대한 민감도 분석을 통해 두 요소의 불확실성을 평가하였다. 분석 대상 시설은 인천 청라지구 1공구에 계획된 빗물이용시설이며, 경제성 분석 기간은 지방공기업법 시행규칙에 제시된 건축물의 내용 연수인 30년으로 하였다. 편익-비용 비율을 이용하여 빗물이용시설의 경제성을 분석한 결과, 저류용량이 285 m³에서 최대 수익률이 나타났으며, 순현재가치는 저류용량이 1105 m³일 때 최대 수익이 발생하는 것으로 분석되었다. 분석 대상 지역의 경우에 285 m³에 대한 양적 신뢰도는 7.3%로 빗물이용시설의 효과를 기대하기 어려운 결과이며, 이와 같은 결과는 편익-비용 비율이 사업의 경제성을 수익률로 평가함에 따라 투자 규모를 반영하지 않는 한계로 인한 것으로 판단된다. 사회적 할인율과물가상승률에 대한 민감도 분석 결과, 사회적 할인율이 낮아지고 물가상승률이 높아짐에 따라 빗물이용시설의 저류용량과 그에 상응하는 최대 순현재가치가 커지는 경향을 보였다. 이는 미래가치를 높게 평가할수록 빗물이용시설의 저류용량이 크게 설계될 수 있음을 의미한다.

Purpose : This study aims to estimate the financial cost of rotavirus infection in Korea in the year of 2005. Methods : The incidence rates used were from the epidemiological profile at Jeoungeub District (5.8 cases/1,000 children <5 years old for inpatients, and 22.65 cases/1,000 children <5 years old for outpatients, per year). The health care cost per capita of rotavirus infection (ICD code: A08.0) was extracted from the Health Insurance Review and Assessment Service database in Korea. The patient survey was conducted to capture information about non-medical costs and associated productivity loss incurred by adult caregivers. Results : The number of annual national cases among children <5 years old with rotavirus infection was estimated to be 69,122 (i.e., 55,030 outpatients and 14,092 inpatients). The total cost of rotavirus infection was estimated at 13.3 billion Korean won, comprising 11 billion Korean won (82.7%) of direct medical costs, 1.6 billion Korean won (12.0%) of direct non-medical costs (e.g., transportation and supplies), and 0.68 billion Korean won (5.1%) of productivity lost by adult caregivers. Conclusion : Rotavirus infection carries not only medical costs but also non-medical and indirect costs; together, these costs incur a significant burden on South Korean society. The impact of rotavirus on quality of life and health among patient caregivers was not considered in this study, but it does merit further research.

This study analyzes the effect of applying hyperbolic social discount rate onto the results of benefit-cost analysis of environmental public investment projects in Korea. In order to check the application possibility to the actual feasibility study, the discount factors generated by hyperbolic function, rather than traditional exponential one, would be applied to the benefit and cost data from the pre-feasibility studies which peformed for environmental public investment projects. The results of this study shows that using hyperbolic social discount rate is effective for enhancing test results, only under the condition of which the full expansion of the time periods of analysis is satisfied. According to the simulation results of this study, to achieve higher benefit/cost ratio by using hyperbolic social discount rate, the period should be increased up to 120 to 150 years at least.

Infrastructure asset management can be defined as the long term and cost effective management strategy to meet the required service level. In most developed countries, the major motivations of the introduction of asset management are increment in number of assets, extension of maintenance field, accounting approaches of public facilities, performance-based FM(Facility Management), limitations of public funds and public-private partnership, life cycle cost approach, and the development of information technology. This paper discusses the strategic and stepwise methods of introducing infrastructure asset management. Strategic approaches are suggested to develop the practical methods of condition and value assessment of assets, and long-term capital investment plan for optimized decision making(ODM). Required systematic processes are analyzed in terms of resource and technical limitations and detailed implementation plan for each development phases are suggested.

External costs emerge as a consequence of negative external effects. The EU commission and national government in Europe made themselves the internalization of external costs and began to make various measures. The traffic sector plays an important role. At the same time, it affects as financial loads to logistics service providers and carriers in Europe. This study examines current development in european logistic market conditions. It describes the reaction of different market players and stakeholders in the logistic value chain in EU, Switzerland and Germany. A portfolio of different strategic answers to the changing market environment is being developed. Therefore, different options for the internalization of external costs are proposed. This study finally derives propositions for future research.

In this paper we have shown that a Pigouvian tax is an adequate resolution of congestion externality to attain Pareto optimality using utility maximization. For this objective, taking an open access freeway as an example, we not only derived both marginal private benefit and marginal social benefit, but also assessed the divergence between marginal private benefit and marginal social benefit. As a result, we identified that the amount of a Pigouvian tax should be the same amount as the external time cost, which is the value of the marginal time cost to Individual a incurred by Individual b through freeway congestion. This Pigouvian tax coincides with the profit or wealth maximizing toll suggested by literature on the basis of profit maximization. In addition, because an open access freeway is accounted as common property resource, we proved that average social congestion cost is essentially equal to marginal private congestion cost in our model. Finally, we showed that the optimal value of trip derived in our model is the same as that generated on profit maximization approach.

Samsung Tesco is a representative company that is successfully enforcing 'sustainable management' through creative, systematic corporate responsibility (CR). The concentration on CR is because of the fact that the modern society expects companies to do a role as a social citizen. For this reason, Samsung Tesco emphasizes that the cost of carrying on CR is an important factor in business which leads to a positive cycle in business, and accordingly is rather an investment than a cost. The reason why Samsung Tesco proclaimed its resolution to make best efforts on CR is because Samsung Tesco thinks CR is a necessary task and responsibility of a company. Samsung Tesco is doing various activities continuously, and is investing by increasing its costs on CR and systemizing the organization. Consequently, Samsung Tesco is being evaluated as the first and best innovative company in the distribution industry. This case study firstly shows the actual conditions of domestic companies in doing CR. Secondly, it analyzes how Samsung Tesco is carrying out the cultural, sharing, and environmental CR. And lastly, it gives some strategic points on successful CR.
