최근 전자상거래의 급격한 발전은 새로운 비즈니스 패러다임을 가져오고 있다. 이러한 디지털 비즈니스 체제로의 성공적인 진입을 위한 지불 수단으로서 전자화폐의 필요성은 갈수록 증대되고 있다. 실용화된 전자화폐를 경제적으로 사용할 수 있는 경제 체제가 확립되면서 전자지불 산업계의 움직임도 활발해지고 있다. 특히, IC카드를 전자 지갑으로써 이용하는 If카드형 전자화폐가 세계적인 규모로 실용화되고 있으며 전자화폐의 업계 표준을 둘러싼 경쟁이 격화되고 있다. 전자화폐의 이용분야도 백화점, 편의점, 체인점, 주유소, 자동판매기 등 유통부문은 물론 버스, 지하철, 주차장, 고속도로 톨게이트 등의 교통 부문으로 확대되고 있다 또한 고궁, 박물관, 관공서 수수료 등 공공서비스 부문에서도 사용할 수 있는 등 일상생활과 밀접한 소액 지불시장에서 이용이 가능하게 되었다. 한편, 디지털 데이터인 전자화폐를 보호하기 위한 보안기술의 개발과 다양한 전자화폐의 상호 호환성을 제공하기 위한 표준의 확립 등이 시급히 요구되고 있다. 본 논문에서는 전자지불 산업계의 활발한 움직임에 맞추어 전자화폐의 실용화, 보급을 지원하는 입장에서 전자화폐의 개념과 분류, 국내외 동향을 살펴보고, 향후 발전 전망에 대해 논하고자 한다.

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.

Forest museums can be defined as facilities for the collection, exhibition, and education of the forest or forest related artifacts or data. This study was performed to measure the educational value of Gyeongnam state forest museum's forest and its environment. The tool used was the Contingent Valuation Methods (CVM) which is well known as a value estimation tool of environmental goods. The study for the value estimation is performed from April, 2014 to October of the same year through selection of the subject, decision of proposed price, and orientation of the survey staffs and total of 386 surveys were used in analysis. The value estimation tool used the DBDC logit model and the input parameters were number of visit (time), degree of environmental education (contri), the environment conservation effort of the respondent (execu), the education level of the respondent (edu), and income of the respondent (inc) and trimmed mean (WTPtruncated) was used. The estimated value of flora and environment education per each person per visit is 23,338 won. When applied to the average annual visitors deducted from 2010 to 2014, which is 430,000 per year, the environmental value that Gyeongnam state forest museum is providing to visitors each year is about 10 billion won. The result of this study is significant to propose the value of forest education and environment that the forest museum is offering to the visitors in the current currency. This is an evidence to directly determine the value of the forest museum and therefore proposing an opportunity change the recognition toward the forest and environment education.

This study describes the processes undertaken for the conservation treatment of metal artifacts excavated in Hasong-ri, Yeongwol, Gangwon-do and the results of the related surface composition analysis. X-ray fluorescence analysis (XRF) was applied to analyze the surface composition of a small gilt-bronze wind chime, two clappers, and a small gourd-shaped bronze bottle. The gourd-shaped bronze bottle was investigated using radiography to examine its internal structure. The wind chime and clappers were excavated from the same location. A gilt layer was identified on the wind chime, but surface corrosion made it difficult to identify any such layers on the clappers. The element analysis revealed that the wind chime was made of bronze in a Cu-Sn-Pb ternary system and was gilt-plated using mercury amalgam. The clappers were made from copper with a small amount of gold detected, but did not show any evidence of mercury. Since a thick corrosion layer was affixed to the surface of each clapper, it was impossible to identify the surface composition and determine if the clappers had been gilded. It is possible that the gold detected from the clappers was a foreign substance or had detached from the giltbronze wind chime buried alongside them. The small gourd-shaped bronze bottle was investigated through surface element analysis and radiography to verify if it was a type of silver bottle used as currency during the Goryeo dynasty. The radiography photography identified that a small hole in the middle of the base had been stopped up. The general surface analysis did not detect silver, which suggests that the bottle was made of bronze instead and was not one of the silver bottles used as a means of currency.
