Exchanging information with a person without credentials over the Internet does not pose any problems. A decentralized system based on blockchain technology enables the user to exchange new value(currency) with other uncredited users. The blockchain technology creates a new paradigm in which the distribution system can be founded on trust. Various applied distribution systems are being developed based on this paradigm. This study analyzed the problems between an institute's grading system and the central administration system. The limitations of an institute's current central management system were presented through actual cases. To improve the problem, a decentralized system based on block chain technology was presented in order to overcome the fundamental limitations by utilizing blockchain technology, peer-to-peer network, and the distribution system. In the central system, a malicious moderator could create a malicious edit that becomes the cause of a dispute, but in a decentralized system, a problem cannot be created even if there were to be a malicious moderator. However, it is difficult for a single college institute to create a distribution system in order to actualize an effective system. Comparatively, it would be possible to create a decentralized system in which all educational institutes in Korea (elementary schools, middle schools, high schools, colleges) took part in. The application of a decentralized system would improve the public transparency and reliability of educational institutes.

The purpose of this study was to compare the accuracy of currently used elastomeric impression materials for complete arch impression taking. Five elastomers (Impregum, Permlastic, Express, Extrude, Examix) and one Irreversible hydrocolloid (Aroma-fine) were tested. For each material, 5 impressions were made of stainless steel model to which five tapered posts were attached. Custom trays were used for polyether and polysulfide impression materials, and putty/wash two step technique was used for addition polyvinylsiloxane impression materials. Improved stone mod els were poured to all impressions. Accuracy of the materials was assessed by measuring ten distances on stone dies poured from impressions of the master model. All measurements for master and improved stone models were made with three dimensional measuring machine. The results were as follows 1. The dimensional accuracy of polyether, extrude, and examix were significantly superior to poly-sulfide, exress, and alginate in reproducing full arch mode (p<0.05) 2. There were no statistical differences in dimensional accuracy for full arch impression between polyether extrude and examix (p>0.05). 3. there were no statistical differences in dimensional accuracy between polysulfide, express, and alginate(p>0.05). 4. There were no statistical differences between addition polyvinyl siloxane materials (p>0.05) 5. There were no statistical differences between anterior-posterior and lateral dimensional changes of all impression materials (p>0.05).

Keratinized ginigva has clinical singificance in periodontal health because it plays important roles in resistance to mechanical trauma, to penetration of bacteria, and to tensional stress by muscle attachment. In order to investigate the width change of anterior keratinized gingvial during transitional period, the width of kerainized gingiva on anterior teeth was measured annually in elementary school children with deciduous dentition until the successive anterior teeth were completely erupted. The distance from the gingival margin on mid-portion of crown to mucogingival junction was measured by Boley gauge(Hu-Friedy, U.S.A.) and was recorded as the width of keratinized gingiva. The difference of the width of keratinized gingiva according to sex and dentition was analyzed statistically by Student t-test. Following results were obtained : 1. In deciduous dentition, it was shown that the width of keratinized gingiva on maxillary central incisors($3.28{\pm}0.83mm$) was the widest(p<0.01), and that on maxillary lateral incisors, mandibular central and lateral incisors was $2.69{\pm}0.86mm$, $2.51{\pm}0.71mm$, $2.43{\pm}0.68mm$, respectively. 2. In mixed dentition, it was shown that the width of keratinized gingiva on maxillary central incisors ($5.10{\pm}0.86$) was the widest(p<0.01), and that on maxillary lateral incisors, mandibular central and lateral incisors was $4.35{\pm}0.83mm$, $3.51{\pm}0.60mm$, $3.57{\pm}0.66mm$, respectively. 3. The width of anterior keratinized gingiva was significantly increased after the successive anterior teeth were completely erupted(p<0.001). The width of keratinized gingiva on maxillary central and lateral incisors, and mandibular central and lateral incisors was increased by $1.82{\pm}0.83mm$, $1.65{\pm}0.69mm$, $0.99{\pm}0.39mm$, and $1.14{\pm}0.98mm$, respectively. 4. There was no statistical significance in the difference of the width of anterior keratinized gingiva between male and female(p>0.05).

Recently, the e-busines market has become a place of convergence where consumers and sup liers communicate with each other, and a new method of trading of funds has emerged in the proces . Crowd-funding is one of the types of money transactions that have emerged in the online space, and its interest and trading volume have be n growing rapidly recently. The platform in the online space using crowd-funding method operates in the form of online telecommunication sales, and it is in the form of producing and delivering products based on funds obtained from potential consumers by the operators involved in securing funds. However, if the participating busines operators do not deliver the product or deliver the product other than the promoted product and avoid responsibility, the potential demander wil not be compensated without mediation by the platform operating entity. In this study, despite the rapid growth in the market size of crowd-funding, consumers who participated in the funding are protected and able to resolve disputes in the event of a conflict amid growing complaints from potential consumers and side ef ects. The structure or method of crowd-funding is a new form of trading that has dif erent features from conventional e-commerce. Therefore, the legal basis is not yet in place and the standards ne d to be laid out through various and suf icient discus ions political y, legal y, social y and cultural y and economical y. As the potential market and positive ef ects of crowd-funding around the world have be n recognized, a role is required as an ecosystem for new financial transactions. And the potential market could be realized as a new industry if the right legal system and policy consultation were made.

최근 관세청이 15개 수입소비재 품목 가격을 분석한 결과, 수입가격 대비 국내 판매가격은 2.1-4.8배 수준인 것으로 나타났다. 이는 아직도 독점 수입업체들이 폭리를 취하고 있다는 것을 보여주는 결과이다. 독점 수입업체가 아닌 제3자가 제품을 수입할 수 있는 병행수입은 1995년 이미 허용되었으나, 위조품 논란, A/S문제 등 때문에 실제 소비자 후생으로 이어지지 못했다. 정부가 최근 병행수입 활성화 정책을 펴면서 지난해 규모가 3조원으로 늘었으나, 아직 전체 소비재 수입의 5%에 불과하다. 관세청이 정식통관 제품이라는 것을 보증해주는 통관인증제 대상 업체와 품목 확대로 통관 인증업체가 344개로 늘어난 것은 매우 다행스런 결과이다. 이에 본 연구는 현재 국내 병행수입 시장의 실태와 문제점을 분석하고, 정부의 「독과점적 소비재 수입 개선방안」 의 검토를 통해 향후 병행수입 제도가 국내 경제 활성화와 수입시장의 경쟁 제고를 위해 나아가야 할 방향을 제시하고자 한다. The megatrends of the Korean distribution industry market in 2014 reflect opportunities in parallel import & overseas direct purchase. Korean government addressed that 「Monopoly & Oligopoly consumer goods import improvement plan」 to stabilizing importing goods prices and domestic consumers` burden relief through accelerating market competition. and moreover it is to improving distribution channel and promoting parallel import market business. The Korean market is very unique in that consumers` real sensory index of open up importation effect level is low, but nominal open up importation effect level is high. This is due to difficulties in creating a proper importing goods distribution market and alternative importing routes are very rare. Thus, the purpose of this study is to analyze the market situation and parallel import to improve Korean government`s 「Monopoly & Oligopoly consumer goods import improvement plan」 policy for the revitalization of the domestic market economy and to boost up a new growth engine industry.
