For child abuse prevention in Korea, this study estimated the socioeconomic costs of child abuse. Based on previous studies, the present study organized component categories for estimable direct and indirect costs of child abuse, and estimated the cost of each category in 2014 through the collection of existing data and through Delphi survey techniques among experts. The total socioeconomic costs of child abuse were compared to Korea's GDP. The results of this study were as follows. First, the socioeconomic costs of child abuse in Korea in 2014 ranged from 389.9 billion KW(0.03 percent compared to GDP) to 76 trillion KW(5.1 percent compared to GDP). Second, the indirect socioeconomic costs of child abuse are much higher than the direct costs. Third, costs related to productivity loss and unemployment accounted for the largest proportion of the total costs. In addition, the proportion of the child protection budget in Korea was very low compared to developed countries. These findings suggest that there is a need to increase Korea's child protection budget and to take urgent action to detect unrevealed child abuse cases. Furthermore, in order to reduce indirect costs, it is important to provide abused children with early professional treatment.

본 연구는 장기투자자인 생명보험사 및 연기금의 투자다변화 일환으로 장기투자의 성격에 부합하고 안정적이며 높은 수익이 기대되는 대체투자 중 사회간접자본 자산에 대한 투자방안을 연구목적으로 하여 다음의 분석결과를 도출하였다. 첫째, 생명보험사와 연기금의 금융부문 수익률과 사회간접자본 투자수익률을 비교한 결과 사회간접자본 투자는 변동성이 큰 주식에 비하여 위험은 낮고 안전자산인 채권에 비해서는 상대적으로 높은 수익률을 나타내었다. 둘째, 생명보험사 및 연기금이 사회간접자본 투자에 참여할 경우 사회간접자본 투자에 대한 정부의 수입보장 및 국내 인프라 사업의 사업수익률 수준과 타기관의 목표수익률 등을 종합적으로 고려할 때 15% 수준의 투자수익률이 적합할 것으로 보인다. 다만 최근 국내 주요 사회간접자본 사업의 투자수익률을 볼 때 국가관리사업과 자체관리사업 모두 투자수익률이 낮아지고 있는 추세이므로 장기적으로 이러한 추세를 반영하여 목표수익률의 재조정이 필요한 것으로 보인다. 셋째, 현실적인 간접투자상품의 한계 및 직접투자시의 비용절감효과 등으로 대규모투자자의 경우 전문성을 확보하여 직접투자방식의 참여를 고려할 수 있으며 중소규모투자자의 경우 시장상황 및 위험을 고려하여 펀드를 조성하여 투자하는 것을 고려할 수 있다. 그리고 중장기적으로는 세계적인 추세에 따라 국내 사회간접자본 간접투자 시장이 활성화되고 규모가 커지게 될 것으로 예상되는 바, 간접투자방식을 적극적으로 검토하여야 할 것이다.

This study estimated the socioeconomic costs of child poverty. Based on previous studies, the present study organized component categories for direct and indirect costs of child poverty, and estimated the cost of each category in 2015 through the collection of existing data and Delphi survey techniques among experts. The total socioeconomic costs of child poverty were compared to Korea's GDP. The results of this study were as follows. First, the socioeconomic costs of child poverty in Korea in 2015 ranged from 55 trillion KW(3.5% of GDP) to 99 trillion KW(6.5% of GDP). Second, the indirect socioeconomic costs of child poverty are much higher than the direct costs. Third, among the total cost categories, costs related to productivity loss and unemployment accounted for the largest portion of both the socioeconomic costs based upon absolute poverty and relative poverty. Crime costs are the second largest. Based on these results, we discussed the importance of early intervention for children in poverty; implementation of two-generation program that intervenes simultaneously with parents and children; and long-term, continuous and integrated intervention for high-risk groups such as poor children.

As critical infrastructure, bridges play an indispensable role in facilitating the distribution of goods. When bridges reach their end of useful life or get damaged by natural disasters such as earthquakes or storms, they have to be removed and reconstructed. When bridges in service need to be reconstructed, user costs occur from vehicle detours and traffic congestions, and social costs occur from noise and dust during construction periods. However, these user and social costs are not considered during reconstruction and the evaluation methods of those costs are vague. Thus, there is lack of appropriate bridge types that consider these costs. Therefore, this paper identifies the social overhead costs that occur during bridge reconstruction, which is also called, users' socioeconomic values. Next, it proposes a method to evaluate user costs during bridge reconstruction, and appraises the method. User costs are evaluated based on traffic information, social and material volumes including the bridge's daily traffic volume, peak hours, detour distance and time. In addition, time delay costs due to traffic operational costs and bridge reconstruction are also taken into consideration.

In this study, DEA (Data Envelopment Analysis) was carried out on the four bridges, which have the same extension (L=1,615m), in order to select the most superior, economical method of construction using the LCC concept of each bridge structure in the case of the Ulsan-Pohang double track railway which is scheduled to be constructed. DEA models were analyzed with the CCR model, which was designed for the evaluation of relative efficiency of each model. The initial construction costs, maintenance costs, indirect costs (user costs + indirect loss of social costs), and life cycle costs were used as input variables, and average duration was applied as the output variable. LCC was applied to calculate the input variables, and to get the costs of LCC, 100 years of period and 4.83% of real discount rate were applied, and the costs are classified into initial construction, maintenance, user, and indirect loss of social cost. The analysis results showed that the Method 2 and 3 were evaluated as the most efficient, and the other alternatives were evaluated as the following order; Method 1, the default, and Method 4.

This paper presents the effects of indirect costs on Life-Cycle-Cost(LCC) effective optimum design of steel-box girder bridges. The LCC formulations considered in the LCC optimization of the bridges consist of initial cost and expected rehabilitation costs including repair/replacement costs, loss of contents or fatality and injury losses, and indirect costs such as road user costs and indirect socio-economic losses. To demonstrate the LCC-effectiveness for optimum design of the bridges, an actual steel box girder bridge having two continuous spans(2@50m=100m) is considered as a numerical example. And also, in this paper, various sensitivity analyses are performed to investigate the effects of indirect costs caused by traffic conditions such as number of detour route, number of lane on detour route, length of detour route, and traffic volumes on the LCC-effective optimum design. From the numerical investigations, it may be concluded that indirect costs caused by traffic network may sensitively influence on the LCC-effective optimum design of steel-box girder bridges. Therefore, it may be stated that the traffic conditions should be considered as one of the important items in the LCC-effective optimum design of the bridges.

현재 정부는 사회간접자본 확충을 통한 물류비용의 절감이라는 궁극적 목표를 위하여 도로터널의 확충 노력을 적극 경주하고 있으며 터널의 규모 또한 급격히 장대화 하고 있다. 또한 환경 및 안전 측면에서의 규제 강화로 인하여 터널환기 시스템이 점점 복잡해져 가고 있는 추세이다. 환기관련 주요 설비는 제트팬, 축류팬, 집진기, 수갱 등으로 대형화 및 자동화에 따라 운영비용 역시 급격히 증가하고 있으며 운영비용 중의 대부분은 현재 일반전기로 분류되어 있는 환기설비에 소요되는 전력비로, 장대터널의 경우 km 당 1 MW를 훨씬 초과하는 경우도 많아 SOC(사회간접자본)사업으로 추진되는 도로터널의 건설 및 운영상의 문제점으로 지적되고 있다.

OECD(2008) gives the concepts of inaction costs on key environmental challenges including: direct financial costs; total financial costs; total use costs; and total social welfare costs. In analyzing the losses of environmental goods' various values conducted by domestic and foreign researchers, this study suggests the value-cost category of OECD(2008) and other studies; and the indirect use and non-use values of groundwater and other natural environment using the concepts of inaction costs. The studies on the damages and their relationships among human, property, and ecosystem are essential to monetary valuation on the qualitative or quantitative degradation of groundwater and other natural environment.

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.

농업부문이 사회에 제공하는 다양한 긍정적 외부효과가 인정됨에 따라, 대부분의 농업생산기반시설은 국부를 증진시키는 사회간접자본으로 인식되고 있다. 과거에는 수리시설을 비롯한 기반시설이 단지 생산성 향상을 위한 사회적 투자로 간주되었으며 따라서 사업에 대한 경제성 분석 또한 직접적인 경제적 효과에 대한 편익비용분석에 국한되었다. 그러나 최근에는 농업 및 생산기반시설이 제공하는 비시장적 가치가 점차 인정됨에 따라 그러한 가치 또한 경제성분석에 포함될 수 있다
