온라인거래가 폭발적으로 증가하면서 온라인결제에 대한 이용자 수요가 증가하고 있다. 특히 최근 들어 온라인소액결제는 다양한 디지털재화(MP3, VOD, 사이버머니 등)를 구입하는 데 활발하게 사용되고 있으며, eBay의 PayPal, 구글의 Checkout 등 해외에선 이미 차세대 온라인 비즈니스 영역으로 주목 받고 있다. 온라인소액결제는 전자 상거래에서 사용되는 결제 방식으로 금액이 작은 온라인 거래에서 사용되는 결제를 말한다. 하지만 온라인소액결제에 대한 국내외적인 성장에도 불구하고 이 분야에 대한 연구는 거의 전무한 상황이다. 본 논문에서는 온라인소비자들이 온라인 환경에서 소액결제를 이용할 때, 선호하는 결제수단과 중요시 여기는 속성에 대한 실증연구를 진행했다. 온라인 소액결제는 연령층에 따라 신용카드 결제와 상품권, 사이버머니 등의 결제 선호로 나뉘어 지고, 개인정보 보장 등과 같은 안전성에 관련된 속성을 중요시 하는 것으로 나타났다. 이와 같은 결과는 향후, 온라인 소액결제에 대한 소비자 특성과 도입 및 발전전략에 대한 다양한 해석을 통해 이비즈니스 분야에 실질적으로 활용될 수 있을 것이다.

최근 건강에 대한 관심이 높아지면서 천연 기능물질을 이용한 고기능 및 고부가가치 상품개발이 여러 산업분야에서 일반화되는 추세이다. 대표적으로 마이크로캡슐은 원하는 기능을 발휘할 수 있는 기능성 물질을 다양한 방법으로 다양한 제품에 부여함으로써, 기능성 물질을 오랜 기간 동안 외부로 방출하거나 외부의 환경으로부터 보호하는 수단으로 각광받고 있다. 이러한 마이크로캡슐은 의약분야 제초제, 멸충제, 곰팡이 방지제, 살균제로 적용되는 농약분야, 식품 분야, 화장품 분야 등의 전반에 걸쳐 응용 및 연구가 활발히 이루어지고 있다. 이에 본 연구에서는 다양한 나노 합성기술과 유/무기 하이브리드를 이용해 서방화 관련 기술을 개발하여 보습성, 항균, 노화방지, 외부 유해물질로부터의 피부보호 특성을 가진 인체 친화형 복합기능성 섬유 가공조제를 개발하여 다양한 섬유소재에 적용하고자 하며, 궁극적으로 기존 선진국 제품의 기능을 뛰어넘는 원천기술, 즉 새로운 가공제 합성과 응용성, 그 성능평가와 동시에 최적의 처리기술을 개발함으로써 섬유제품의 부가가치를 높이는 계기를 마련하고자 한다. 본 연구에서는 나노미터 직경을 갖는 침상형의 주형(hydroxyapatite)을 이용하여 중공 나노구조체를 제조 한 후 이에 천연고분자를 혼합하여 초음파처리 후 유/무기 하이브리드 기술을 이용한 서방성 가공제를 합성하였다. 중공의 나노구조체 확인은 투과전자현미경(TEM)을 이용하였으며, 주형의 나노구조체는 주사전자현미경(FE-SEM)으로 확인하였다. 이상의 결과를 통해 본 연구에서 제안한 방법이 나노구조체의 새로운 합성방법으로써 가능성을 확인할 수 있었다.

As visiting of Chinese tourists to Korea have increased gradually, Chinese people who use online travel reservation services for their visits to Korea have increased accordingly. In addition, the growth of the online reservation services in China is very rapid. Therefore, it is necessary to study the factors affecting the Chinese tourists' intention to use the online travel reservation services in order to advance e-business in the travel industry. This paper presents a new research model based on Technology Acceptance Model (TAM) including perceived risk, service factors, online reviews and user satisfaction. Also, it analyzes factors affecting the Chinese tourists' intention to use the online travel reservation services. The results of this study show that the key influencers of the online travel reservation services are perceived usefulness, perceived ease, and perceived risk. Additionally, based on these results, this paper proposes practical suggestions to solve the existing problems and improve online travel reservation websites in China.

Since the concept of virtual currency called Bitcoin was announced in 2008, the blockchain technology, which is the basis of Bitcoin, is attracting attention as an important platform technology in the era of the 4th industrial revolution that can change our society in the future. Although Existing electronic financial transactions store and manage all transaction history at a reliable central organization such as government and bank, blockchain-based electronic financial transactions are composed of a distributed structure in which all participants participating in the transaction store and manage the transaction history, it is possible to secure transaction transparency while reducing system construction and operation costs. Besides the virtual currency that started with bit coins, the technology of these blockchains has been extended in various fields such as smart contracts and document management. The key technology area of this blockchain is security based on proven cryptographic technology to make it difficult to forge and hack, but there are security risks such as security vulnerabilities in the virtual currency trading service, We will discuss security risks in using virtual currency and discuss countermeasures. Especially security accidents of virtual currency exchanges are occurring frequently recently, the damage of users who trade the virtual currency is also increasing, we propose security threats and security countermeasures against virtual currency exchanges.

It becomes common thing that many customers buy the goods through the online shopping mall as internet grows very fast. The information cascades that happen when a person imitates the other's acts also it occurs in online. Many people buy the goods referring on other people's purchasing experiences and such cases are spreading more and more. Through numerous existing researches, the researches in association with this issue have been studied on the information cascades effect on offline or online separately. The research of comparing the information cascades effects from the offline word of mouth (WOM) and the online review has not studied yet. On that reason this study shows that the online review induces the information cascades. We also compared the effects with information cascades effects from traditional offline word of mouth. In result of this study, the following points have been concluded. Firstly, we examined that information cascades was occurred through both the online review and offline word of mouth. Secondly, the information cascades effect through the online review is greater than through the offline words of mouth. It means the company has to understand the importance of the online review and manage it. Thirdly, the information cascades effects are occurred differently in accordance with the goods brands. Therefore a company has to know whether its products is superior to the competitor's one or not.

The effect of Phellinus linteus methanol extract on the lipid metabolism in the liver of rat was investigated in this study. Rats were randomly divided into 6 groups including the control, $CCl_4$and high fat group plus sub-groups with Phellinus linteus methanol extract administration. Methanol extracts of Phellinus linteus were fed 50mg/kg B.W daily via drinking water. A 1.2mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total six times. The administration of $CCl_4$ increased total cholesterol, TG, LDL and LDL-phospholipid. However, the level of liver cholesterol and triglycerides were significantly decreased while HDL-cholesterol was increased by the extract feeding. The activities of GOT, GPT, AP and LDH were greatly enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ treatment deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract treatment reconstituted the damaged cytoplasm and stimulated mitochondriagenesis. From these results, it was suggested that Phellinus linteus can help to recover the damaged liver function and further may help to prevent senescence diseases such as fatty liver, hypertension and hyperlipidemia.

We have carried out the development for hydraulic breaker which can be operated by optimal mode with ICT convergence technology. This developed system can predict the rock properties. Moreover, this system can maximize the energy efficient with intelligent control of hydraulic system. In order to provide the optimal impact force, this system can measure the descending depth of piston with the proximity sensor and discriminate the rock properties with the measuring data and control the piston stroke using solenoid valve eventually. In addition, we have developed the controller, display module and operating device for cascade (multi-level impact) system and applied the module which can communicate each system by wireless communications. In conclusion, the control system which can control the multi-level impact in accordance with strength of rocks has been developed and approved by several field tests.
