The present study was performed to evaluate the effects of Tetracycline-HCI on the microstructure change of SLA implant surface according to application time. In the Tetracycline-HCI group, 6 implants were rubbed with sponges soaked $50mg/m{\ell}$ Tetracycline-HCI solution for O.5min., lmin., 1. 5min., 2min., 2.5min. and 3min. In the saline group. another 6 implants conditioned with sponges soaked saline using same methods. One implant wasn't conditioned anything. Then, the changes of surface roughness values were evaluated by optical interferometer & specimens were processed for scanning electron microscopic observation. The results of this study were as follows: 1. In both Tetracycline-HCI group & saline group, there are no significant differences between surface roughness values before & after surface detoxification. And in scanning electron microscopic observation. there are slightly changes of implant surface structures but this changes were not significant by comparison with no treatment implant surface. 2. In the changes of surface roughness values & the scanning electron microscopic observation, there were no significant differences between saline & Tetracycline-HCI groups. In conclusion, the detoxification with $50mg/m{\ell}$ Tetracycline-HCI within 3 minutes can be applied for treatment of peri-implantitis in SLA surface implants. without surface microstructure changes.

This paper gropes how to connect philosophy of household management(PHM) to real life. PHM is to think and to act for better quality of life, so PHM should contain not only theory but also practice in itself. In that sense, PHM is consist of two parts: one is viewpoints how to deal with home management and the other is practice. This paper presents 5 main viewpoints of PHM. Then, it explains PHM can connect with education of human nature, and ecological value in PHM can connect with practice of life. Also, it proposes a guide for practice.
A Pilot Case Study of an OPIc Test Oriented Class: The Effect of Providing Formative Assessments
서미란,장선미 한국영어교과교육학회 2013 영어교과교육 Vol.12 No.2
This study was conducted as a pilot case study to investigate whether providing a recording assignment as a formative assessment helps L2 adult learners in improving their OPIc (Oral Proficiency Interview-Computer)1grades. The class observed in the study was a four week (six hrs./w)intensive course with eight participants working for one of major corporations in Korea. The participants took the class on site with financial support by the company. After every lesson, they were asked to submit an answer for an OPIc question by recording the answer using their smart phones. The improvement was measured by comparing the pre-test grade of OPIc to the post-test grade of OPIc. Half of the learners completed the assignment and three of them showed one or two levels improvement while those who failed to complete the assignment showed no improvement including the two who were not able to report the post test. The results of the study was interpreted and some suggestions for the future research are offered with conclusions.

이 글은 4차 산업혁명 시대의 도래에 맞춰 무형자산의 가치가 더 높아지고 있는 현시점에서, 최근 수년간 쟁점이 되는 지식재산권 관리에 관한 문제를 다룬다. 지식재산권은 재산권으로서 독점배타적으로 사용할 수 있으며, 이에 대한 침해가 일어나면 이를 회복할 수 있는 권리를 갖고, 지식재산권을 활용하여 발생하는 소득을 취득할 수 있으며, 지식재산권을 양도 등 자유롭게 처분할 수 있는 권한을 갖게된다. 이러한 지식재산권이 재산권으로서 권리를 행사하기 위하여는 지식재산권에 대한 가치평가 체계를 확립하고, 이를 적극적으로 활용하도록 장려할 필요가 있다. 지식재산권의 기술가치평가를 위해서는 기술성 분석과 지식재산권의 권리성 분석, 시장성 분석, 사업성 분석이 필요하다. 따라서, 기술가치평가는 기술전문가, 권리성 분석을 위한 특허전문가(변리사 등), 시장성 분석을 위한 시장전문가, 사업성 분석을 위한 사업분석가와 필요시 기술이전 전문가 등으로 구성된 평가팀에 의해 공동으로 수행되어야 최적의 기술가치평가가 이루어질 수 있을 것이다. 그런 의미에서 현행 ‘감평법 시행령’과 같이 저작권, 산업재산권을 포함한 무형자산에 대한 감정을 할 수 있는 자를 감정평가사로 한정하는 것은 바람직하지 않다. 따라서, 변리사법 등의 법개정을 통해 변리사의 감정평가 업무를 명문화하여 지식재산 가치평가에 있어서는 변리사와 감정평가사가 서로 협업할 수 있는 환경이 마련되어야 할 것이다.

With increase of multi-drug resistant Escherichia coli in community-acquired urinary tractinfections (CA-UTI), other treatment option with a therapeutic efficacy and a low antibioticselective pressure is necessary. In this study, we evaluated in vitro susceptibility of E. coliisolates from CA-UTI to fosfomycin (FM), nitrofurantoin (NI), temocillin (TMO) as well astrimethoprim-sulfamethoxazole (SMX), ciprofloxacin (CIP) and cefepime (FEP). Theminimal inhibitory concentrations were determined by E-test or agar dilution methodaccording to the Clinical and Laboratory Standards Institute guidelines, using 346 E. colicollected in 12 Korean hospitals from March 2010 to February 2011. FM, NI and TMOshowed an excellent susceptibility profile; FM 100% (346/346), TMO 96.8% (335/346),and NI 99.4% (344/346). Conversely, resistance rates of CIP and SMX were 22% (76/346)and 29.2% (101/349), respectively. FEP still retained an activity of 98.5%. In Korea, NI andTMO in addition to FM are a good therapeutic option for uncomplicated CA-UTI, especiallyfor lower UTI.
