In order to enhance cutting efficiency of reed culms, we had assessed diverse methodology in cutting and applied better conditions among them into three vigorous eco-types of common reed. From the results, differences in a eco-type, a sampling area in reed population and substrata affected the shoot emergence slightly. On the other hand, differences in a type of burying culms and a burying part among whole culm affected shoot emergence strongly. Our results suggest that not only methodological condition but also appropriate kind of eco-types must be considered in using reed culms for better cutting. In addition that, sampling timing according to the geological and climatic condition of certain area should be considered for better cutting efficiency as well. We also recommend that the sampling area such as expanding area in a population, burying a middle part of the culm, substratum such as well-ventilated sand and vertical burying method for better cutting efficiency. Lastly, for more enhancement of cutting efficiency of reed culms, potential damages by blight and harmful insects such like aphids should be concerned very carefully.

As environmental issues are rising recently efforts to reduce environmental stress are emerging in all industry segments. Especially environmental impact of buildings occupy a critical portion, so each country is operating green building rating system for life cycle of buildings. Accordingly green building rating system for every facility is operating in Korea. And acquisition of grade I for building energy efficiency is mandatory for every new public buildings since 2010. To design green building efficiently and systematically eco-friendly elements should be considered and checked from the schematic design phase. But in many cases eco-friendly elements are checked at the end of constructed design phase. So applying eco-friendly elements at the value engineering process, which is performing through schematic and constructed design phase, could make a efficient and systematic green building design. Value engineering process is divided into pre workshop, workshop and post workshop stages. And subject selection in pre workshop stage is the step that finds out the subjects which has the great possibility to be improved to perform efficient value engineering workshop. So this study present the Green VE subject selection model to select the most considerable eco-friendly subjects in projects.

Due to the increase of aged housing demolition in preparation for the rapid growth of the market, Eco-friendly remodeling demolition work which can minimize environmental destruction have been studied. However, the owner or contractor to apply for eco-friendly remodeling demolition work does not reflect the characteristics of the site can not have a potential for many variables. In addition, There is no standard which can find effective part and catch a problem by performing eco-friendly remodeling demolition. Therefore, the project owner and construction company executives in the Pre-construction stage to the implementation of eco-friendly remodeling demolition construction by providing a model for the pre-evaluating the project. In this paper, the performance of eco-friendly remodeling of demolitions is proposed for the pre-evaluating model. After the eight items were drawn affecting the performances which are influence to accomplishment of the eco-friendly remodeling demolition, evaluation criteria was suggested for each item. Also By classifying and assessing the evaluation items, It will be able to identify the problems and supplements for eco-friendly remodeling demolition. Through the final evaluation sheet, The works of the appropriacy and supplement will be checked for the eco-friendly remodeling demolition. Finally The preinvestigation model is helpful for making the plan of systematic demolition, futhermore It is contribute to the expansion of the eco-friendly remodeling demolition.

Recently, application case of the ultra rapid hardening concrete-polymer composite(URHCPC) are increasing to repair for the deterioration of pavement. But it is a major disadvantage that the main material is expensive and has environmental load. For these reasons, the development of the economic, eco-friendly materials is needed. Calcium Aluminate Composite (CAC), produced by rapid cooling of atomizing method with molten ladle furnace slag, is a material capable of improving the economic feasibility and reducing the environmental load of URHCPC. In this paper, the properties of CAC and gypsum mixed CAC (GC) as alternative materials of RSC according to the types of polymer dispersion were studied. The results were as follows; compressive strength, tensile strength, flexural strength, bonding strength and modulus of elasticity of the composites using CAC or GC showed higher values than those of plain proportion in 3 hour. In later age, they were at the same level as the general proportions. URHCPC using BPD as polymer dispersion had superior strength properties generally. But modulus of elasticity was the same level as the case of using a SBR latex. According to these results, CAC or GC can partially substituted for RSC to product the URHCPC. When URHCPC uses the BPD as the polymer dispersion, it can be improved performance.

Objectives The purpose of this study was to verify the effect of integrative Korean medicine on acute postoperative pain after arthroscopic shoulder surgery. Methods This study was conducted in a retrospective observational way. Patients who met the inclusion criteria were divided into integrative Korean medicine-treated group (IKM group) and no integrative Korean medicine treated-group (No IKM group). The primary outcome was the difference in the amount of change in pain intensity. The secondary outcome was the difference in pain intensity, opioid consumption over time, and the number of adverse events after surgery. Results The change of numerical rating scale for pain intensity from baseline to IKM group was 3.09±2.12, while 2.64±1.80 in no IKM group, and the difference of change between two groups was statistically significant (p<0.05). Difference in the use of opioid between two groups over time after surgery was also statistically significant (p=0.000). Conclusions The results of this study suggest that integrative Korean medicine can be effective for acute postoperative pain after arthroscopic shoulder surgery.

This paper examined the supply chain management Integration factors and environmental performance in Korean industry. Focusing on SCM Integration, GreenSCM practice, and environmental performance factors, purpose of this study is finding linkage between SCM Integration factors with new environmental practice factors and environmental performance. Based on the analysis of eighty-eight cases, the following results were found. First, We found External environmental collaboration factors and Internal environmental monitoring factors within Green Supply Chain Practices. Second, SCM Integration have a positively significant influence on environmental performance. Third, Internal environmental monitoring factors have a positively significant influence on Environmental performance but External environmental collaboration factors doesn't. This study suggests that only with high level of Integration firms may have good result on entire supply chain environmental performance. Finally, our empirical evidence shows that company should be prepared for new environmental trade regulation with Green Supply chain management integration.

최근 환경오염 문제 및 자원고갈 문제가 심각하게 대두되고 있으며 국가 간의 에너지 및 자원 분쟁이 일어나고 있는 실정으로 국내에서도 환경규제 강화 및 자원절약 및 고부가가치화에 대한 관심이 집중되고 있다. 이에 따라 친환경 소재에 대한 기술개발도 절실히 요구되고 있다. 이를 위해서 정부에서 환경 규제뿐만 아니라 다양한 정책지원이 이루어지고 산 학 연 기관에서 공동연구 등을 통해 보다 다양한 친환경 재료 기술을 개발하고 부존자원의 고부가가치화를 이룬다면 친환경 재료분야의 장래는 밝다고 할 수 있다.

201X년, 환경인증을 획득하지 못하고 친환경 인쇄공정 관리기술도 보유하지 못한 인쇄업체 A사는 더 이상 주문을 받지 못하고 있다. 더욱이 오랜 고객사이던 C사로부터 친환경 인쇄공정 기술을 보유하지 못했기 때문에 더 이상 인쇄물을 발주할 수 없다는 "통보"를 받았다. 또한 탄소배출권을 확보하지 못했기 때문에 이를 구매하기 위한 비용이 증가해 생산비용의 증가로 가격경쟁력이 악화되어 어려움이 가중되고 있다. 이에 비해 서울 근교의 다른 인쇄사인 B사는 계속되는 인쇄물 발주에 응하느라 바쁘다. 귀찮기는 했어도 친환경인쇄 공정기술을 획득한데 이어 환경인증도 일찌감치 받아 놓았기 때문이다. 또한 다른 업체들에 앞서 한발 빠르게 탄소배출권을 충분히 확보해 가격경쟁력에서도 앞서고 있다.
