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.

서미란,이미나 사단법인 인문사회과학기술융합학회 2019 예술인문사회융합멀티미디어논문지 Vol.9 No.1

This study is implemented to know effects of a music play program using body expression on self-esteem and emotional intelligence of child. The research problem is that a body expression baby music play affects self-esteem and emotional intelligence of child. Subjects of the study are 20 experimental groups and 20 control groups that are 5-year old babies attending W children education institute at S region. The research tools are self-esteem test tool of Dan and Lee(2006), and the criterion developed by Lee(1997) based on the model of emotional intelligence of Mayer and Salovey(1990) for measuring emotional intelligence. The data are analyzed by t-test to know the difference using SPSS 20.0. As a result of the study, musical play using physical expression was effective on the self - esteem and emotional intelligence of young children. In other words, musical play is important not only in early childhood education but also in children 's self - esteem and emotional state, especially when they play musical play using physical expression. Music play activity is applied in early childhood education Suggesting a very good fit. 본 연구는 신체표현을 통한 유아음악놀이프로그램이 유아의 자아존중감과 정서지능에 미치는 효과를 알아보고자 실시하였다. 연구문제는 신체표현 유아음악놀이가 유아의 자아존중감에 효과가 있는가? 신체표현 유아음악놀이가 유아의 정서지능에 효과가 있는가?이다. 연구대상은 S시 지역 W유아교육기관 재원중인 5세를 실험집단과 통제집단 각 20명씩을 선정하였다. 연구도구는 단현국과 이미숙(2006)의 자아존중감 검사도구와 정서지능을 측정하기 위하여 Mayer와 Salovey(1990)의 정서지능 모형에 기초한 이병래(1997)가 개발한 척도를 사용하였다. 자료분석은 SPSS 20.0을 사용하여 각 집단간 평균과 표준편차를 산출하고 집단 간 차이검증을 알아보고자 t검증을 실시하였다. 연구결과, 신체표현을 활용한 음악놀이가 유아의 자아존중감 및 정서지능에 효과가 있었다. 즉, 유아교육현장에서 음악놀이가 중요할 뿐만 아니라 특히, 신체표현을 활용한 음악놀이를 진행하였을 때, 유아는 자존감 및 정서성에 보다 적극적으로 표현하였으며, 음악놀이 활동은 유아교육현장에서 적용하기에 매우 적합함을 시사해주고 있다.

지식재산권관리에 관한 실무적 고찰

서미란 충남대학교 세종지적재산권연구소 2023 The Journal of Law & IP Vol.13 No.1

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.

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.

Analyzing Co-occurring Errors of Adult L2 Learners in Speaking and Writing PDTs

서미란,장선미 한국영어어문교육학회 2020 영어어문교육 Vol.26 No.1

This study was conducted to determine whether South Korean L2 adult learners’ errors in speaking and writing co-occur. It also focused on answering whether Picture Description Task (PDT) can elicit enough language production to analyze errors in both speaking and writing. Eleven university students participated in the study completing ten paired sets of PDTs. The order of speaking and writing tasks was switched and different pictures were used throughout every set of PDT. The most common errors found in speaking and writing PDTs were the use of determiners, verbs, and prepositions respectively. The speaking errors outnumbered writing errors but the types of errors in speaking and writing appeared very similar along with the smaller language features of each category. This confirmed that whether it is speaking or writing, determiners, verbs, and prepositions are the three most common areas where L2 learners commit errors. The participants showed low level of confidence in speaking and more errors were made whenever a speaking description was given first. This suggests in PDTs teachers can lower learners’ L2 anxiety by presenting writing tasks first. PDTs practically activated L2 productions and made the comparison between speaking and writing outputs possible.

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.
