서은실,구본학,Seo, Eun-Sil,Koo, Bon-Hak 한국조경학회 2015 韓國造景學會誌 Vol.43 No.5

고령화 및 다문화, 사회적약자의 외부활동이 증가됨에 따라 장애물 없는 생활환경의 구축이 요구되고 있어 공원에서도 이들의 편리한 이용을 위한 시설개선이 요구되고 있다. 이에 '장애물 없는 생활환경 인증제도'에 따른 기존공원의 BF인증 가능성을 분석하고, BF인증평가기준을 적용한 공원 계획을 수립하였다. 공원 오는 길 및 공원 내 주요 시설지를 연결하는 무장애 동선을 확보하고, 주요 시설이용에 불편함이 없도록 공원시설을 개선하며, 장애인 등의 이용이 편리하도록 안내체계를 개선하여 보라매공원을 무장애 공원으로 조성하고자 하였다. 본 연구는 기존 도시공원의 BF인증 가능성 여부를 진단해 보고, 누구나 이용하기 편리한 무장애공원 계획을 수립했다는데 의의가 있다. 연구를 진행하면서 BF인증제도의 한계점과 과제도 발견할 수 있었는데, 첫째는 BF인증제도에 대한 이해와 인식부족이다. 공원의 계획, 설계단계에서부터 장애물 없는 생활환경 조성을 위한 고려가 필요하나 설계 및 공사완료시점에 인증에 대한 검토를 함으로써 시간적, 경제적 손실이 큰 실정이다. 둘째는 공원의 BF인증 평가항목이 지형의 기복 및 기존 수목 등의 자연적 제약조건이 큰 외부공간의 특성이 반영되지 못한 세부평가항목을 적용하고 있다는 점이다. 셋째는 공원의 입지적 여건을 고려한 무장애 공원의 가이드라인 수립 및 공원의 BF인증 평가항목 등의 개선이 필요하다는 것이다. With the trend for the construction of barrier-free living environments in accordance with the ever-increasing external activity of the aging population, multi-culture families and socially disadvantaged, there is also a demand for the facilities improvement at parks for their convenience of use. This study analyzed the possibility of Barrier-Free Certification of an existing open space and defined its prototype renovation plan. This study is intended to help develop Borame Park into a barrier-free park by securing a barrier-free line of movement linking the major facilities sites within the park, improving park facilities lest there should be inconvenience in the use of the major facilities, and a guidance system convenient for use by physically and mentally impaired people. The significance of this study lies in the fact that it diagnosed the possibility of the BF Certification of existing urban parks and established a barrier-free park, which is easy for anyone to use. In the course of doing research on this, this study was able to discover the limitations of the BF Certification system, and its related tasks to be solved in the future as follows: The first thing this study shows is that there is a lack of understanding and awareness of the BF Certification system. Basically, there is a need for giving consideration to the development of a barrier-free living environment from the planning and design phase of a park, but in actuality, an examination of the certification is undertaken at the time of the completion of design and construction, which causes a large loss both time-wise and economically. Second, as evaluative items for the BF Certification of a park, applied are detailed evaluation items that fail to reflect the characteristics of an outdoor space whose natural constraints are large, such as geographical highs and lows and existing trees, plants, etc. Third, guidelines for establishment of a barrier-free park must be created in the light of the locational conditions of the park, followed by improvements of its BF Certification evaluation items.

서은실,박노국,장원철,이병권,이태진 한국화학공학회 2002 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.40 No.1

메탄올과 CO_2로부터 디메틸카보네이트(DMC)의 직접합성은 간단한 공정이고, 독성이 적고 가격이 싼 CO_2를 활용하기 때문에 가장 매력적인 대체공정으로 주목을 받고 있다. 그러나, 직접합성은 열역학적 평형의 제약을 강하게 받는 가역반응이다. CeO_2 또는 Ce_(1-χ)Zr_χO_2 촉매를 사용하여 선택성이 뛰어나게 메탄올과 CO_2 만으로 DMC를 합성하였다. DMC의 수율은 반응온도 150℃까지는 증가하였고 그 이상의 온도에서는 감소하였다. CO_2와 메탄올의 농도 역시 DMC 수율에 명백한 영향을 보였다. 촉매들의 산-염기의 이원기능이 DMC 형성과 관련이 있으며, 다양한 실험결과로부터 DMC 형성에 대한 반응기구를 제안하였다. The direct synthesis of dimethyl carbonate(DMC) from methanol and CO_2 is considered to be the most attractive alternative route due to its simple process, less toxicity and the low-cost of CO_2. Unfortunately, the direct synthesis is a reversible reaction and is strongly limited by thermodynamic equilibrium. DMC was synthesized from methanol and CO_2 with high selectivity using CeO_2 or Ce_(1-χ)Zr_χO_2 catalysts. The yield of DMC increased with the reaction temperature, reached maximum at 150℃, and decreased above 150℃. The concentration of CO_2 and methanol showed also an obvious influence on yield of DMC. The acid-base bifunction on catalysts was related to the DMC formation. The formation mechanism of DMC was proposed based on the experimental results.

The Use of Group Drumming With Korean Middle School Students in School Violence Prevention

서은실 한국음악치료교육학회 2017 인간행동과 음악연구 Vol.14 No.1

The purpose of this study was to examine how a therapeutic drumming intervention would impact middle school students with regard to school violence prevention. Participants were all in the third-year class of a middle school in Korea. A school music teacher and a music therapist designed and implemented the program collaboratively, and mainly used dyadic, synchronized, and improvisational drumming based on the Social Emotional Learning core competencies. A total of 65 students participated in a weekly 45-minute program for 10 weeks. Ten participants out of 65 were selected for interviews and the rest of the 55 participants were asked to fill out an open-ended survey. Content analysis of the survey and interviews produced 492 meaningful statements, which were categorized into seven themes: somatic responses to drumming, emotional processing, group cohesion, empathy, relationship with peers, self-esteem, and self-regulation. The findings indicated that dyadic, synchronized, and improvisational drumming may promote prosocial behaviors in students of this age. The author discussed that drumming produces physical input directly from the instruments, which prompts students to identify and empathize with their own or others’ emotions. This study therefore suggests that collaborative work between school music teachers and music therapists may positively impact middle school students’ prosocial behaviors, as they pertain to school violence in Korea.

MODI를 활용한 피지컬 컴퓨팅 수업 운영 및 만족도

서은실(Eunsil Seo) 한국공학교육학회 2023 공학교육연구 Vol.26 No.1

Recently, the Internet of Things is attracting attention as an important key technology of the 4th Industrial Revolution, and SW education using physical computing is suggested as a good alternative to supplement the problems raised by beginners in programming education. Among the many teaching tools that can be used for physical computing education, MODI is a modular manufacturing tool that anyone can easily assemble like Lego. MODI is a teaching tool that can improve learners’ achievement by linking a self-linked block-type code editor called MODI Studio to lay the foundation for programming in a relatively small amount of time and immediately check the results in person. In this paper, a physical computing education method using MODI was designed to be applied to basic programming courses for programming beginners and applied to after-school classes for middle school students. As a result, it was found that students’ interest and satisfaction were much higher in physical computing classes using MODI than in text-based programming classes. It can be seen that physical computing education that allows beginners to see and feel the results in person is more effective than grammar-oriented text programming, and it can have a positive effect on improving basic programming skills by increasing students’ participation.

초등 예비교사의 교실영어 오류분석

서은실(Seo Eun Sil),이완기(Lee Won Key) 한국초등영어교육학회 2016 초등영어교육 Vol.22 No.2

The purpose of this study is to investigate the English errors of 24 university students who participated in a preparation course for the state-run teacher employment test. The data were collected from the participants' classroom English, which was produced in their 6-minute long, mock microteaching sessions. The errors they made were analyzed and categorized in terms of three aspects: grammar, lexicon and pronunciation. Their errors were more closely analyzed in four types: ommission, selection, addition and ordering. Further investigation was made in the level of English proficiency and their beliefs and expectations on the use of classroom English. The results showed that frequent errors were found in the order of grammar, vocabulary and pronunciation. Also, the most common grammatical errors were found in omission of articles, third person singular s, and objects. In lexical errors, the selection or addition of words was frequently found. With regard to pronunciation, the participants made a great portion of errors in the selection of appropriate consonants or vowels. In addition, the participants of lower proficiency made errors almost twice as often as the ones of higher proficiency. On the basis of these results, some pedagogical implications were drawn for the pre-service primary teacher education.

Ce1-xZrxO2 촉매에 의한 디메틸카보네이트의 직접합성

서은실(Eun Sil Seo),박노국(No Kuk Park),장원철(Won Chul Chang),이태진(Tae Jin Lee),이병권(Byung Gwon Lee) 한국공업화학회 2002 공업화학 Vol.13 No.3

메탄올과 CO_2로부터 디메틸카보네이트(DMC)의 직접합성은 간단한 공정이고, 독성이 적고 가격이 싼 CO_2를 활용하기 ??문에 가장 매력적인 대체공정으로 주목을 받고 있다. 메탄올과 CO_2로 부터 DMC의 선택적 합성이 citric complexation technique에 의해 제조된 Ce_(1-x)Zr_xO_2 촉매들에서 효과적으로 수행되었다. 다양한 조성을 갖는 Ce-Zr 복합산화물로부터 Ce_(1-x)Zr_xO_2의 고용체가 적절하게 형성되었음을 XRD를 확인하였다. DMC 생성속도는 Ce_(1-x)Zr_xO_2에서 Zr 함량에 크게 의존하였고 Ce_0.8Zr_0.2O_2 촉매가 가장 높은 활성을 나타내었다. TEA와 CO_2의 TPD 결과로부터 Ce_(1-x)Zr_xO_2 표면에 이웃한 산-염기점들이 반응성과 관련지울 수 있음을 알 수 있었다. 다양한 실험결과로부터 DMC 형성에 대한 반응기구를 제안하였다. The direct synthesis of dimethyl carbonate (DMC) from methanol and CO_2 is considered to be the most attractive among many alternative routes because it is simple, less toxic and low-cost of CO_2. The selective synthesis of DMC from methanol and CO_2 proceeded effectively via Ce_(1-x)Zr_xO_2 catalysts that were prepared by the citric acid complexation technique. XRD analysis indicated that the solid-solutions of Ce_(1-x)Zr_xO_2 were formed from Ce-Zr mixed oxides of various compositions. The DMC formation rate was strongly dependent on the Zr content of Ce_(1-x)Zr_xO_2 Ce_0.8Zr_0.2O_2 catalyst exhibited the best reaction activity. The catalytic activity seemed to be related to neighboring acid-base sites on the Ce_(1-x)Zr_xO_2 surface as shown by the results of TPD of TEA and CO_2. The formation mechanism of DMC was proposed by using the experimental results.

In order to investigate the effects of Yukmijihwang-Tang on the hepatic microsomal function of Cd-poisoned rats, 3mg/kg of cadmium (Cd) and 500mg/kg of Yukmijihwang-Tang extract (YJT), a herbal hepatoprotective medicine, were administered concurrently to rats for 4 weeks. The levels of protein, aniline hydroxylase (AH) and malondialdehyde (MDA) were increased in Cd-treated group. This increase was suppressed by treatment of YJT. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose-6-phosphatase (G-6-P) and delta-aminolevulinic acid dehydratase (ALAD) of Cd-treated group were decreased. This decrease was inhibited by treatment of YJT. Treatment with YJT significantly protects cadmium-induced hepatotoxicity.
