최근 경제협력개발기구(OECD)보고서에 따르면 세계 교역량의 80%가 표준의 영향을 받고 있으며, 유럽연합(EU) 무역의 50%는 강제규격 인증을 요구하고 있다. 이로인해 각 기업과 국가들은 산업별 신기술에 대한 연구개발(R&D)과 연계하여 자신들의 신기술에 대한 표준창출과 이를 국제 표준화하는데 사활을 건 경쟁을 벌이고 있다. 즉, 기술표준은 생산비용 절감에서 시장지배 수단으로서 전 산업분야에 걸쳐 표준을 주도하는 집단이 시장을 지배하는 경쟁시대 관점에서 보다 적극적인 개념으로 이해할 필요성이 있다. 건설표준화는 건설R&D 성과 확산에 있어 중요한 역할을 수행하는 분야로 예측되며, 건설공사기준, KS표준 등에 반영되어 향후 글로벌 시장에서 경쟁력 강화를 위해 필수적인 전략이 된다. 그럼에도 국내 건설산업은 제조업에 비해 표준화 관련연구 및 정책적 관점의 분석이 상대적으로 미흡하였다. 이에 본 연구에서는 건설R&D사업과 표준화의 연계 관점에서 성과에 따른 효과를 분석하기 위한 기준을 정립하고자 한다. 또한, 이를 기반으로 기 종료된 건설R&D과제 성과로부터 도출된 표준 산출물(Output)의 특성과 그에 따른 파급효과 분석을 통해 국내 건설기술표준화의 가치를 제고할 수 있는 기반을 제시하고자 한다. According to the report from OECD, 80% of world trade quantity was influenced by standard, 50% of EU trade demand certification of forced standard. This leads to develop standard connected with R&D in most country and company worldwide. Recently, Technical standards have advantage of reduction of production cost and market dominating power. Standardization of construction technology has very important role that ouput of R&D refer to KS, national construction standards and it activates in the market. However, domestic construction research related to effectiveness of standadization fall short of expectation in comparison with manufacturing industry. This study present criteria that can analyze the performance and effectiveness in construction R&D project connected with standardization. And it applied domestic R&D cases (finished from 2000 to 2009), analyzes ouput of standadization and economic effect to verify the value of construcion technology standardization.

Platelet-rich plasma (PRP) has been used as an alternative to non-operative treatments for increasing the rate of cure in bone and soft-tissue regeneration, although there are very few clinical studies regarding the treatment of articular cartilage damage. Therefore, our study proposes non-surgical intervention for patients with articular car-tilage damage and who are experiencing knee pain caused by this damage. This study was conducted as a single medical center. It was an uncontrolled, prospective clinical trial, and the study subjects included 44 patients who were suffering from early osteoarthritis and degenerative chondropathy; they were between 18 and 65 years of age and were included in the study irregardless their sex. PRP was injected twice intraarticulary within an interval of four weeks. The pain scores and functional scores were compared two months, four months, and six months follow-ing the second injection was completed, using the VAS, the Lysholm knee scale, and the Cincinnati knee rating sys-tem. There were no complications related to the PRP injection. The pain experienced by the study patients two months after the PRP injection was reduced compared to the pain felt before the injection, and the reduction in pain after four and six months compared to the pain experienced two months after the PRP injection was statistically sig-nificant. From a functional viewpoint, there was a statistically significant improvement in their pain during the entire follow-up period. Our study results suggest that PRP injection is an effective and safe treatment for the management of early osteoarthritis and degenerative chondropathy, as seen in this clinical trial.
