본 논문은 지역간의 경쟁을 통한 환경재의 획득과정에 대해서 분석하였으며, 특히 경쟁의 과정에서 자발적 참여집단 (critical mass)의 존재가 경쟁의 결과에 미치는 영향에 초점을 맞추고 있다. 환경재에 대한 지역간의 경쟁(지대추구경쟁)은 Katz-Nitzan-Rosenberg(1990) 모형을 기초로하여 분석하였으며 지역집단간의 경쟁에 있어서, 구성원은 비협조적 쿠르노-내쉬(Cournot-Nash) 방식에 의해서, 그 자신의 이익(지대)을 획득하기 위한 경쟁을 벌이는 것으로 가정하였다. 어떤 지역집단이 환경재 획득경쟁에서 이길 확률은 궁극적으로 그 지역에 유치될 환경재의 크기(화폐가치로 환산한)에서 받는 영향의 정도 ${\alpha}$( 단. $0{\leq}{\alpha}{\leq}1$)의 상대적 크기에 비례하여 결정된다. 그러나 환경재획득경쟁에서 발생하는 고정비용 M의 규모가 커지면, 그것이 특정지역의 자발적 참여집단의 최소규모 상향조정을 요구하게 되어, 자발적 참여집단의 수가 경쟁에 결정적 영향을 미칠 가능성이 많게 된다. 특히 환경재로부터 받는 영향의 정도인 ${\alpha}$의 값이 작은 집단은 큰 집단에 비하여 항상 더 많은 자발적 참여집단의 구성원 수를 요구받게 되며, 고정비용 M의 값이 계속 커짐에 따라 이러한 최소한의 자발적 참여집단의 구성원수의 증가속도도 경쟁집단에 비하여 점점 더 커지게 된다.

In case of low benefit project with low traffic or high-priced project, existing analysis of cost and benefit tends to present a low feasibility. However, considering the improvement of environment, intensification of disaster prevention, public stability of countryside area and formation of good scenery, these projects can have a feasibility. This paper analyzes and summarizes the indirect benefit of some ripple effects, caused by road projects, and presents the methodology and process in order to change the indirect benefit into monetary value.

This paper analyzes the changes in financial reform during the Kim Jong-un era based on North Korean literature. We find that North Korea has systematically and functionally separated the central bank from commercial banks since the Kim Jong-un era began. In addition, enterprises have been allowed to withdraw cash from bank accounts and make inter-enterprise cash payments. In other words, nowadays non-cash currencies with passive money can partially serve as active money with purchasing power. With the systematic and functional separation of the central bank and the commercial bank, the issuance of the central bank changed to a money supply method through the commercial bank, and changes in the currency distribution structure have allowed commercial bank's credit creation function to be implemented. This means that the banking system and the monetary·payment system of the socialist planned economy are changing in the way of the market economy. Reforms in the financial sector are believed to have been necessary to support changes in the economic system and to restore the function of the public financial sector. These changes have progressed in terms of the level of reform, but they are still considered similar to the period of the former Soviet Union's Perestroika or to the early period of China's reform and opening. Although North Korea's financial reform is superior in terms of enacting the banking law, it is insufficient in terms of realizing the functions of commercial banks. In addition, it is assessed that institutional constraints such as maintaining a planned economy, and the lack of confidence in public finances limit the effectiveness and development of the financial system. It should be noted that these results are based on literature published in North Korea. In other words, there is a limit in the fact that such recent changes have been carried out on a trial basis in some areas, or have been carried out in a full-scale manner with a blueprint, since Kim Jong-un's inauguration.

This study investigates the impact of exchange rate and exchange rate volatility on the stock prices of eight industries from 2006 to 2015. The first and second exchange rate exposure of these eight industries is estimated with respect to four different exchange rates, namely the US dollar, Japanese yen, European currency unit, and British pound. In exchange rate exposure, stock prices in foods-beverages, paper-wood, electricity-gas, and banks industries are negatively related to exchange rate, whereas stock prices in electrical-electronic equp. and transport-equp. industries are positively related to exchange rate as expected. However stock price in machinery industry is negatively related to exchange rate, which is opposite to the expectation. Negative relationship is found between stock price in chemicals industry and exchange rate. In exchange rate volatility exposure, stock price in paper-wood industry is found to be negatively related to exchange rate volatility. Stock price in banks industry is also negatively related to exchange rate volatility. This result is opposite as expected, because banks are supposed to get more revenue by issuing derivatives related to foreign exchange when exchange rate volatility increases.

Local area festivals have grown on a scale for the past 20 years, but have suffered ups and downs. Through the trial and error of the festival operation, problems such as prediction of the number of visitors, planning of event scale, calculation and expansion of sales volume, and management of various participants in the duration were highlighted. To solve, this study designed and developed a mobile payment system and festival operation management system for local scale festivals as a platform operating system of web and app combined. The results of this study presents four basic functions. It includes ticketing management, attendance identification and entrance control, charge of festival currency and use of payments, real-time provision and management of related information, and performance reporting for each role. It was applied to local festivals in practice as to enable local shop owners to participate in advertisements or sponsorships and confirmed their contribution to local commercial market and the revitalization of festivals through this system.

This study investigated the effect of the money resource on the resource use behaviors of undergraduate students. The aim of the study was the examination of the relationship between undergraduate income and clothes-purchasing behavior. A total of 415 undergraduates residing in Gwangju City and Chonnam Province were interviewed by means of a questionnaire. SPSS 12.0 software was used for statistical analysis. Cronbach's $\alpha$, t-test, one-way ANOVA, Duncan's multiple range analysis and chi-square analysis were all conducted to acquire the results. The main results of this study are as follows. First, the average undergraduate income average was relatively high. Second, the motive for clothing purchases by undergraduates was to buy clothes similar to those which they already had. The undergraduates acquired their purchasing information from past experiences of buying clothes and considered design, quality and color when choosing their clothing. They purchased their clothes at retail stores and on average bought clothes about once a month. Although theaverage monthly expenditure on clothes was over 100,000 won, in general, the undergraduates spent between 50,000 and 100,000 won a month. They mainly paid cash when they purchased their clothes. Third, by analyzing the income, clothes-purchasing behavior, and clothes purchasing frequency of undergraduates, significant statistical differences in average monthly clothes expenditure and payment methods were detected. The results of the study can be used to understand the patterns of undergraduate money resource usage behaviors and can be utilized as an educational resource at home and within educational institutions.

Bitcoin is an electronic money that does not rely on centralized institutions such as banks and financial institutions, unlike the world's paper currencies such as dollar, won, euro and yen. In Bitcoin network, a block with transaction details is generated by mining, and the message that the block has been created is broadcast to all participating nodes in a broadcasting method to secure reliability through verification. Likewise, the mining and block propagation methods in the Bitcoin network are greatly affected by the performance of the P2P network. For example, in the case of mining, the node receiving the reward for mining varies depending on whether the block is first mined in the network and the proof of mining is propagated faster. In this paper, we applied local characteristics and Round-to-Trip(RTT) measurement to solve the problems of the existing neighbor connection method and block propagation method performed in Bitcoin network. An algorithm to improve block propagation speed is presented. Through experiments, we compare the performance of the improved algorithm with the existing algorithm to verify that the overall block propagation time is reduced.

This paper presents an archaeological interpretation of the results of conservation treatment and scientific analysis of the ancient Chinese bronze coin known as Huo Quan(貨泉) coins excavated from Tomb No. 4 at the Madeung Archaeological Site in Heukcheon-ri, Haenam. Huo Quan coins were issued in China by Wang Mang(王莽) when he founded the short-lived Xin(新) Dynasty and were used in the Samhan(三韓) period in Korea. A total of thirteen Huo Quan coins were excavated from the Madeung Archeological Site with some coins fused to each other. They were classified as clusters A, B, and C. On a coin from the B cluster the classical Chinese characters "貨泉" are visible to the naked eye, but no characters are visually identifiable in the other coins. For conservation treatment, foreign substances attached to the surfaces of the coins were removed, weak materials were reinforced with protective coatings, and fragments were reattached to the main bodies of the coins. Next, Nano CT scanning was conducted to identify the exact number of coins within the clusters and examine the surface condition of the coins. It revealed the inscription "貨泉" on twelve out of thirteen coins. In addition to these coins excavated from Heukcheon-ri, a number of coins were excavated from a tomb in Bokryong-dong, Gwangju. This necessitates an investigation into the possible development of a monetary economy in this region.

환경 중 오염물질 중에는 발암물질로 판명된 물질이 수 종 포함되어 있으며, 여러 선진국에서는 방대한 연구를 통하여 오염수준을 파악하고, 위해성 평가에 근거한 관리대책을 펴가고 있다. 하지만 여러 선진국에서는 이러한 인체 위해성 평가결과만을 사용하여 환경 정책을 결정하기에는 그 결과가 반영하는 시야(scope)가 협소함을 느끼고, 다양한 측면(생태, 사회ㆍ경제, 삶의 질 등)을 함께 고려해야한다고 강조하고 있다. 이 중 인체 위해성 평가 결과를 경제성 평가와 더불어 화폐가치화 하는 연구는 정책 결정자들과 일반인들에게 위해성 평가 결과를 쉽게 인지시키고, 비교를 더욱 편이하게 할 수 있다는 장점이 있으며, 현재 많은 연구가 진행되고 있다.
