        PURPOSES : Long-life asphalt pavements are used widely in developed countries. In order to be able to devise an effective maintenance strategy for such pavements, in this study, we evaluated the performance of the long-life asphalt pavements constructed along the national highways in South Korea. Further, an economic evaluation of the long-life asphalt pavements was performed based on a life-cycle cost analysis. We aimed to devise a model for evaluating the performance of long-life asphalt pavements using the national highway pavement management system (PMS) database as well as for analyzing the economic feasibility of such pavements, in order to promote their use in South Korea. METHODS : The maintenance history and pavement performance data were obtained from the national highway PMS database. The pavement performances for a total of 292 sections of 10 lanes (5 northbound lanes and 5 eastbound lanes) of national highways were used in this study. Models to predict the performances of hot mix asphalt (HMA) and long-life asphalt pavements under two distinct traffic conditions were developed using a simple regression method. Further, the economic feasibility of long-life asphalt pavements was evaluated using the Korea Pavement Management System (KoPMS). RESULTS : We developed service-life prediction models based on the traffic volume and the equivalent of single-axle load and found that long-life asphalt pavements have service lives 50% longer than those of HMA pavements. Further, the results of the economic analysis showed that long-life asphalt pavements are superior in terms of various economic indexes, including user cost, delay cost, total cost, and user benefits, even though their maintenance cost is higher than that of HMA pavements. A comparison of the economic feasibilities of the various groups showed that group A is superior to HMA pavements in all aspects except in terms of the maintenance criterion (crack 20% or higher) as per the NPV index. However, the long-life asphalt pavements in group B were superior in terms of the maintenance criterion (crack 25% or higher) regardless of the economic feasibility. CONCLUSIONS: The service life of long-life asphalt pavements was found to be approximately 50% longer than that of HMA pavements, regardless of the traffic volume characteristics. The economic feasibility of long-life asphalt pavements was evaluated based on the KoPMS. The results of the economic analysis were the following: long-life asphalt pavements are exceptional in terms of almost all factors, such as user cost, delay cost, total cost, and user benefit; however, the exception is the maintenance cost. Further, the economic feasibility of the long-life asphalt pavements in group B was found to be better than that of the HMA pavements (crack 25% or higher).

        The KLF(Kruppel-like factors) are transcriptional regulators that including the C2H2 zinc-finger motif and regulation of cell growth, cell differentiation, and development. In this study, mRNA and total DNA was extracted from the meat around the backbone of 130 cattle that has economic traits score. The KLF11 gene was act on the center of the main pathway in associated with the development and growth of cells and the fat metabolism. Genetic polymorphism was detected by DNA sequencing. A total of four SNPs(G9047A, C9104G, G9131A, C9170T) were identified in exon 4 regions, statistical association analysis revealed that the G9131A polymorphism were significantly associated with marbling score. The real time quantitative PCR to investigated gene and miRNA expression patterns and identify the relation of economic trait in Korean Native Beef Cattle. Gene expression level linked to KLF11 genes was investigated by determining its association and variation with the economic traits in Korean Native Beef Cattle. The increment of KLF11 gene expresstion level is resulted in increasing marbling score(MS). We found that expression profile of KLF gene and mir-494 was contrast tendency because the lower expression ratio of gene was the higher marbling score rating was when we analyzed expression profile ofKLF gene and mir-494. Therefore, this result has useful in improvement of livestock in Korean cattle.

        The purpose of this study is to find out the economic impacts of the CASSAVA project, IPM project, Post-Harvest project, and RICE project among 12 projects that are being worked on by the Asian Food & Agriculture Cooperation Initiative(AFACI) established in 2009. Reliable data such as FAO STAT etc. was utilized for the analysis on the economic impacts of each project and the data of an investigation on principal investigators of the nation who participate in each project was used for the analysis of the additional necessary information. According to the economic impacts analysis result, the economic impacts will occur and can be measured as an economic costs as follows: a total of $1,187,404 in Thailand for the next 19 years through the CASSAVA project, $2,358,299 in Indonesia for the next 18 years through the Post-Harvest project, $62,451,317 in Vietnam for the next 13 years through the Post- Harvest project and $60,629,555 in Nepal for the next 13 years through the RICE project. The AFACI project is a small project that annually supports each country that participates each project with approximately $ 10,000. Despite the small-scale project, the estimated result of economic impacts showed that great economic impacts occurred for its scale of the support. Thus, it is deemed that a search for ongoing methods that contribute to the role expansion of Korea and the agricultural development of the recipient country will be needed through the expansion and complementation of a low-cost and high efficiency Official Development Assistance(ODA) such as the AFACI project.

        창조경제는 새정부 출범과 함께 제시된 새로운 경제발전의 패러다임이다. 정 부가 창조경제 정책을 추진한지 3년째를 맞이하고 있으나 창조경제의 규모와 추진 성과에 대한 실감형 분석체계는 부족한 편이다. 이에 본 연구에서는 창조경제 정책 추진의 경제적 파급효과를 정량적으로 추정하기 위한 새로운 방법을 제안한다. 먼저 국내외 창조경제 문헌 검토를 통해 문화⋅콘텐츠, SW 산업 등 외국에서 정의되었던 창조경제의 범위를 협의의 창 조산업군으로 정의하고, 우리 정부에서 제시한 고기술⋅첨단제조업, 과학기술서비스업 등을 추가적으로 포괄하여 광의의 창조산업군을 정의하였다. 다음으로 각 산업군 별로 창조경제 의 핵심 동인 중 하나인 ICT기반 혁신에 따른 투입-산출의 연도별 증감액을 추정하고 산업 연관분석을 통해 창조산업 내 ICT 기반 혁신이 전체 산업에 미치는 경제적 파급효과를 추 정하였다. 분석 결과 2013년 이후 전반적인 경기 하락세에서도 광의의 창조산업에서의 ICT기반 혁 신이 전 산업의 생산, 부가가치 및 고용유발효과의 상승세를 견인하고 있음을 확인할 수 있 었다. 그러나 협의의 창조산업군에서는 ICT기반 혁신의 경제적 파급효과의 증가가 미미한 것을 확인하였다. 본 연구는 크게 두 가지 관점에서 이론적, 정책적 의의가 있다. 첫째로 기 존의 창조경제 성과지표가 투입 역량 중심으로 되어 있어 가시적 효과를 산정하기 어려운 상 황에서 산업연관분석을 통한 산출 중심의 성과를 추정하는 새로운 방법론적 토대를 제공하 였다. 두 번째로 기존의 창조산업 파급효과가 단순히 해당 산업군의 규모 추정에 그쳐 추상 적이고 모호하였다면, 본 분석에서는 창조산업의 전체 규모 중에서 ICT기반 혁신활동이 설 명하는 파급효과를 구체적으로 산출하여 효과 산정의 타당성과 신뢰성을 높였다는 점이다.

        본 연구에서는 노인복지정책을 통해 한국 복지국가의 유형 및 특성, 한국 사회의 생산체제와 사회 불평등의 관계를 파악하고자 한다. 한국은 2018년에는 ‘고령사회’에 진입할 것으로 전망되고 있으며, 고령 사회로의 진입은 사회의 다양한 분야에 영향을 끼치고 있는데 주택, 의료, 사회복지 등 여러 분야에 영향 을 끼침으로써 사회비용을 증가시키고 있다. 즉 고령화 사회는 노인의 문제 좀더 나아가 그 부양가족만의 문제 뿐만이 아닌 전 국가적 문제로서 노령화에 따른 다양한 사회문제를 해결하지 못할 경우 전 국가적 부담과 사회적 재앙이 될 수 있기 때문에 국가 사회적 대응책이 시급하다. 노인의 빈곤은 노년기 경제생활의 취약성과 전생애에 걸쳐 누적되는 빈곤에 대한 위협, 가족이전 소득에 기대고 있는 공공부조의 취약 등을 들 수 있다. 이러한 현황 분석을 통하여 바람직한 노인정책을 방향을 제시하고자 하였다. 사적 이전 소득의 감소로 인한 공공부조 정책의 공고성, 노인 건강정책과 장기요 양서비스의 현실화, 퇴직제도의 개선과 사회복지 서비스의 욕구에 맞는 현실성 등을 제시하였다.

        The economic effects of sewage and wastewater treatment service (SWTS) sector on other sectors have been rarely investigated in the literature. This paper attempts to apply an inter-industry analysis to looking into the economic effects of the SWTS sector. To this end, the most recently published 2012 input-output table is used here. In particular, the SWTS sector is specified as exogeneous to identify the economic effects of the SWTS sector on other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are also analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect and value-added creation effect of a unit of investment or production in SWTS sector are estimated to be 1.7076 and 0.7392, respectively. The employment-inducing effect of one billion of investment or production in the SWTS sector is computed to be 11.0498 persons. The shortage effect of the SWTS sector amounts to 0.8417 won. The overall price effect of the 10% increase in the price of SWTS sector is calculated to be 0.0115%. This quantitative information can be utilized in predicting the economic effects of the SWTS sector-related activities or policy-making.

        It is difficult to make an accurate estimate of the economic value and effects on societal economy of Nano-technologies. This research measures an economic value of Nano-technologies quantitatively and analyzes its influences on societal economy. This paper chooses some major industries as analysis targets and adapts the DEFRA comparative methodology model which has been developed in the UK and recommended by OECD. For this reason, some industries which are in range of economic value assessment were investigated and related data were collected. Also, the economic value and societal influences of Nano-technologies were calculated, through the procedure of the model. In addition, this study conducts a questionnaire to experts for the validity of measurement results and procedures. This paper suggests a guideline for economic value and effects on societal economy of Nano-technologies assessments through quantitative Defra comparative methodologies.

        Over the last 30 years the extent of sea-ice covering the North Pole has declined about 15∼20% on average, and it is expected that by the end of the 21st century, vast areas of the Arctic Ocean will be ice-free during the summer season, thus, increasing the possibility of ship navigation across the Arctic Ocean. In this paper, we have developed a model of shipping for the Northwest Passage (hereinafter NWP) in northern Canada to determine whether ice thinning will make this route more economically viable when compared with the Panama Canal. Among the 7 routes of the NWP, Route 2 and Route 3 offer better navigational conditions than the others. However, Route 3 has a depth limit of only 10m, so here we use Route 2 which is suitable for deep draft navigation to carry on our analysis. Container ships of 4,500∼15,000 TEU under Hub and spoke mode, container shipping between Busan port and New York port is simulated for the Panama Canal and the NWP. This paper considers Canada’s sovereignty in matters of navigation over the waters at the Arctic Archipelago, in the form of a toll fee for passage usage. We concluded that the NWP has an advantage over the Panama Canal if it is open for free international passage, regardless of ship size. However, if it is not free, its advantages depend on its toll fee. The lower the toll fee is, the more advantages the NWP will boast.

        Economic fluctuation has a remarkable influence on firms and their performance (e.g., Deleersnyder, Dekimpe, Sarvavy, & Parker, 2004; Srinivasan, Rangaswamy, & Lilien, 2005). Given the extreme conditions and frequency of recessions (since World War II, recessions have occurred every six years; Srinivasan et al., 2005), understanding what kind of marketing is effective across the different phases of the economic cycle is a crucial question for marketers (e.g., Steenkamp & Fang, 2011; Srinivasan, Lilien, & Sridhar, 2011). In business-to-business markets, characterized by a strong emphasis on long-term customer relationships (e.g., Grönroos, 1997), the ability to gain a deep understanding of customers and their changing needs is a central determinant of firm performance. Therefore, in such markets, market orientation (MO) provides a particularly important source of competitive advantage. During an economic crisis, MO may also serve as an effective shelter against declining firm performance, particularly in industrial markets (Alajoutsijärvi, Klint, & Tikkanen, 2001). The key rationale is that highly market-oriented firms are able to rapidly and accurately identify changes in the marketplace and respond to shifting customer needs and competitors’ actions (Narver & Slater, 1990). While a vast body of literature evidences MO in general to yield performance gains for firms (Kirca, Jayachandran, & Bearden, 2005), some recent studies (e.g., Kumar, Jones, Venkatesan, & Leone, 2011) have questioned this relationship. Recent empirical studies (e.g., De Luca, Verona, & Vicari, 2010; Noble, Sinha, & Kumar, 2002) also propose that the different components of MO (i.e., customer orientation, competitor orientation and interfunctional coordination) may result in different performance outcomes. Furthermore, recent studies have shown the economic environment to play an important role in determining the performance outcomes and, thus, effective forms of MO (cf. Smirnova, Naudé, Henneberg, Mouzas, & Kouchtch, 2011). In this study, using panel data of 140 firms from before and after the great financial crisis, we examine the performance implications of distinct forms of MO 1) over the changing economic cycle 2) among different types of business-to-business focused firms. Employing ordinary least squares regression analysis, our findings suggest that MO and its distinct components yield varying performance impacts from economic upturn to downturn. Specifically, the impact of MO increases during downturn, with interfunctional coordination boosting performance and competitor orientation becoming detrimental. Subsequently, employing configurational analysis (fuzzy set qualitative comparative analysis), our findings further indicate that the role and the most effective forms of MO vary across industry sectors, with MO having a particularly strong impact among firms operating in business-to-business services. We also conclude that, in a growing economy the role of MO has become more of a cost of competing (Kumar et al., 2011), whereas in an economic downturn MO still provides a valuable shelter against performance declines. Finally, our empirical findings are in line with contingency arguments, and suggest that the successful ways for a firm to relate with its markets depend on the dynamic firm- and industry-specific settings.

        This study is aimed to analyze the economic performance of black rockfish aquaculture by standardizing cost structures by region and farming size. The result of survey on farming and sale condition in each region, stocking density, survival rate, juvenile price, and unit production was the highest at Yeosu and Tongyeong, Heuksando showed the lowest. While rearing period was the longest at Tongyeong, the shortest region was Yeosu and Wando. In farming cost structure by region, amount of feeing was the highest at Tongyeong and Yeosu, and the lowest was Heuksando. Cost of medicine was high in Wando and Taean region, Yeosu and Hecksando was low. In case of farm size, feed cost ratio was high in the order of medium(0.75ha), small(0.25ha) and large(1.25ha) size. Standard production cost at every farm size of Heuksando showed the lowest among these regions. Taean and Yeosu was middle, and Tongyeong and Wando was the highest. According to the income, profit rate and investment return of farm size in all regions, as the bigger farm size, the higher income and profit rate was revealed. However, in case of Wando, Taean, and Heuksando which regions has high investment return, medium farm size was higher than large size. The result of economic analysis according to various factors, economic feasibility of black rockfish aquaculture in marine floating cage was showed significant changes by rearing and market condition.

        최근 서비스 산업이 성장하면서 창업활동이 매우 활성화되고 있다. 창업활동은 경제에 새로운 활력을 불어넣어준다는 측면에서 경제성장에 긍정적인 영향을 미친다고 알려져 있지만 어떤 과정을 통해 경제성장률을 제고시키는지에 대한 연구는 매우 부족한 실정이다. 이에 본 연구에서는 금융시스템의 발전단계에 따라 창업활동이 경제성장에 미치는 영향이 어떻게 달라지는지 분석하였다. 분석대상을 고소득 국가군과 중간소득 국가군으로 구분하여 실증 분석한 결과 창업활동은 모든 분석 국가집단에서 경제성장에 유의한 양(+)의 영향을 미치는 것으로 나타났다. 한편, 금융시스템의 발전단계를 고려한 분석결과에 따르면, 고소득 국가군에서는 창업활동이 시장 중심 금융시스템의 발달과 연계하여 경제성장에 영향을 미치고 있었지만 중간소득 국가군에서는 은행 중심 금융시스템과 상호작용하여 경제성장에 영향을 미치는 것으로 나타났다. 하지만 금융시스템의 발전단계와의 상호작용변수의 추정계수는 유의한 음(-)의 값을 보였다. 이러한 결과는 창업활동이 경제성장에 미치는 긍정적인 효과가 금융시스템의 발전에 의해 오히려 약화된다는 것을 의미한다. 따라서 기존의 금융시스템 외에 창업활동을 지원하는 금융 서비스를 정책적으로 강화하는 것이 매우 중요하다고 여겨진다. 그러나 장기적인 관점에서 정책적으로 직접적인 창업자금을 조달하기보다는 시장을 이용한 자본조달 시스템을 강화하는 한편 창업 실패에 대한 안전장치를 마련하는 등의 추가적인 조치를 취하는 것이 바람직할 것이다.

        This paper deals with the economic value analysis of meteorological forecasts for a hypothetical inventory decision-making situation in the pharmaceutical industry. The value of Asian dust (AD) forecasts is assessed in terms of the expected value of profits by using a decision tree, which is transformed from the specific payoff structure. The forecast user is assumed to determine the inventory level by considering base profit, inventory cost, and lost sales cost. We estimate the information value of AD forecasts by comparing the two cases of decision-making with or without the AD forecast. The proposed method is verified for the real data of AD forecasts and events in Seoul during the period 2004~2008. The results indicate that AD forecasts can provide the forecast users with benefits, which have various ranges of values according to the relative rate of inventory and lost sales cost.
