Today as the scale of e-commerce constantly expands, the number and the amount of the consumer frauds are also increasing very rapidly, without sufficient levels of systematic support to prevent them. Internet Escrow service is one of the promising payment mechanisms, which guarantees secure electronic trades and payments. Especially, if the real-time product delivery information is available via RFID-based track-and-trace environment, the security and efficiency of the Internet Escrow services would be improved a lot. In this research, proposed a novel approach to integrate EPCglobal Network, which is a de-facto standard for RFID-based information network model, with Internet Escrow services. The proposed service model was implemented in the form of "Integrated Financial Platform", which supports the contracts among trading partners and the payment via Escrow services by being fully integrated with bank systems. Using the implemented EPCglobal Network-based Escrow service system, we would be able not only to shorten the money-flow cycle and to develop new kinds of loan services, but also to overcome the problems of existing Escrow services including the lack of product-related information and the delay of purchasing decisions.

This study aims to analyze the interregional trade and industrial linkage between the Incheon regional economy and the rest of the nation. An interregional input-output table developed by the Bank of Korea's Incheon branch(2007) was employed for this. The analysis of interregional trade shows that Incheon regional economy is strongly interrelated with Seoul and Gyeonggi regional economies. The Incheon's interregional relationship with other regions was analyzed in terms of output dependency rate, output inducement rate, backward linkage, and forward linkage. The results indicated that while the output of Incheon is more dependent on final demands in Seoul and Gyeonggi, changes of the final demand in Incheon cause more output in the rest of nation than that in Seoul and Gyeonggi. Also, while Incheon's backward linkage to Seoul and Gyeonggi is weaker than that to the rest of nation, Incheon's forward linkage to Seoul and Gyeonggi is stronger than that to the rest of nation.

Date of Bureau of Statistics, including those of Bank of Korea and KDI, in 1995 indicates a market scale of approximately ￦2,800,000,000 in jewelry and personal ornaments, witch points out an average growth rate of 15.3% a year for ten years from 1986 up to 1995, representing a occupancy ratio of 0.78% per G.N.P. Despite the fact that the jewelry and personal ornaments industry has the possibility of high growth it raises problems such as illegal transactions, distortion of quality grades of jewelry (price deference by appraising agencies in Diamond, fabrications of quality in Gold). Furthermore, the personal ornaments market may be said to be still at an early state, as compared with that of advanced countries, including the USA and Japan, due to the small scale of the industry's distribution firms. Accordingly, in order for us to develop the jewelry and personal ornaments industry, one of the value added projects, an improvement in the distribution system of the jewelry and personal ornaments industry. Development of techniques of production and new design, ect, are required. Futhermore, the industry is expected to develop when its importance and contribution to the national economy, a correct understanding of the long-term vision of the industry are expended to all the industries.

This paper mainly estimates a trajectory of GDP induced by variations in fiscal expenditure and taxation policy using three variable structural VAR models. By assigning different combinations of identifying restrictions on the disturbances and measuring the corresponding fiscal multipliers, we compare how robust the estimated values of fiscal multipliers are with respect to the restrictions. Then, considering the dependency of Korean economy on the foreign sector, we extend the three variable SVARs to four variable ones by adding a variable reflecting external shocks. Empirical analyses into the Korean quarterly data (from 1979 to 2000) with the three variable SVARs reveal that the size and the significance of the estimated fiscal multipliers in Korea are very small and low or they decay very fast. Results from the four variable SVARs confirm these results while the significance of the effectiveness of fiscal policy is enhanced in some cases.

From the respect of economics, environmental industry has not defined clearly since environmental services and goods are so broad to focus. Therefore many countries are using their own version of environmental industry. Hence analysis of environmental industry is very limited. In this thesis, based on the definition of Bureau Statistical Office in Korea, economic analysis for the industrial spill effect, production effect, value-added effect has been done by using 1995, 1998 I-O tables published from the Bank of Korea. Even if portion of production from environmental industry in Korea is quite low so far, forward and backward effect has quite impact on the whole industry and show strong intermediate goods. With respect to price effect.

인류의 발전과 함께 재난관리에 대한 발전도 이루어져 왔다. 그러나 세계은행(World Bank)의 조사에 의하면 지난 30년간 전 세계적으로 자연재해로 인해 250만 명의 사람이 목숨을 잃었고, 피해금액은 4조 달러에 이르는 것으로 나타나, 아직 재난관리 체계에 많은 문제점이 있음이 드러났다. 특히, 우리나라는 각종 재난으로 인해 최근 10년(2006~2015)간 연 평균 약 5천억원의 피해액과, 약 1조 1천억원의 복구비를 지출하고 있다(국민안전처, 2016). 만약 재난 피해 발생 전 피해규모와 영향을 신속하게 추정할 수 있다면, 예방 및 대비 차원의 재난관리를 통해 피해액이 크게 감소될 것이다. 따라서 본 연구에서는 국내 재해의 65% 이상을 차지하고 있는 호우피해를 대상으로, 피해 예측함수를 개발하였다. 한강 권역을 본 연구의 대상지역으로 선정하였고, 재해연보자료를 조사하여 대상지역의 호우피해 발생 현황 및 피해액을 분석하였다. 또한 대상지역의 강우자료를 확보하기 위해 종관기상관측소의 강우자료를 확보하였다. 강우자료를 이용하여 지속시간별(1~24시간) 최대강우 자료와 재해기간별 선행강우(1~5일) 자료, 그리고 재해기간의 총 강우량 자료를 산출하였다. 이를 독립변수로 하여 재해기간의 시설물별 피해액과의 분석을 통해 호우피해 예측함수를 개발하였다. 호우피해 예측함수는 피해액을 로지스틱회귀분석을 통해 호우피해액이 큰 범위와 호우피해액이 작은 범위로 분류한 혼합분포를 이용하여 개발하였다. 본 연구는 효과적인 재해 관리체계를 확립 하고, 재해예방 및 대비 단계의 기초 자료로 사용될 수 있을 것으로 기대된다.

Since the end of 1997, the Korean economy has been in deep recession; the unemployment rate has rocketed to 6.7% and the economic growth rate has dropped to -3.8% in the first quarter of 1998. Facing with this mass unemployment, the Korean Government launched comprehensive countermeasures against mass unemployment.. However, these have been in severe criticism from the outset on account of ineffectiveness and impracticability. It is in this regard that this paper purports to design a socially acceptable and financially feasible social safety net by reforming the Livelihood Aid Programme. For this purpose, chapter 3 defines the concept of social safety net, and chapter 4 reviews the social safety net programmes sponsored by World Bank and IMF in the Third World countries and Eastern European countries. Chapter 5 proposes the Three Step Approach in designing the social safety net in Korea.

This study aims to contribute to the early detection of occupational fraud in the Korean financial industry by analyzing fraud symptoms. Firstly, the definition, cause of occupational fraud, and fraud symptoms were discussed through literature review. Secondly, survey data were collected from the employees of the financial industry such as bank, insurance, and securities companies to conduct statistical analysis. The result of analysis showed that the symptoms of 'excessive stock investment' and 'unsettled life style' were statistically significant predictors of fraud detection experience. Plus, 'tips and complaints' were the most frequent method for detecting occupational fraud in the Korean financial industry. The financial institutions can minimize the loss of occupational fraud by early detection through educating their employees and vendors on these important symptoms of occupational fraud.
