      • 1P-436: The Process development of bio-adipic acid with Al-surported Re catalyst

        신나라,권소현,김영규 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

        The growing concern of the depletion of fossil fuel reserves and increasing energy demands have encouraged the exploration of new process develoment for converting biomass into valuable chemicals and renewable fuel components. From this point of veiw, we have recentry developed the synthetic process of the adipic acid which is one of the most important dicarboxylic acid, annually produced about 2.5 bilion kilograms and mainly used for the monomerof nylon from the most abundant monosaccharide galctose. To remove rech oxygen contents, we applied DODH reaction, rhenium catalyzed reduction, and it was successfully appied to afford the desired product with good efficiency. Especiallly, here in we would like to report DODH reaction with heterogeneous aluminium supported rhenium catalyst which intended to esay seperation and recycle.

        Astrocytic Expression of CTMP Following an Excitotoxic Lesion in the Mouse Hippocampus

        신나라,이민희,김세나,백현정,Ursula L. Triantafillu,박종선,김동운 한국뇌신경과학회 2017 Experimental Neurobiology Vol.26 No.1

        Akt (also known as protein kinase B, PKB) has been seen to play a role in astrocyte activation of neuroprotection; however, the underlying mechanism on deregulation of Akt signaling in brain injuries is not fully understood. We investigated the role of carboxy-terminal modulator protein (CTMP), an endogenous Akt inhibitor, in brain injury following kainic acid (KA)-induced neurodegeneration of mouse hippocampus. In control mice, there was a weak signal for CTMP in the hippocampus, but CTMP was markedly increased in the astrocytes 3 days after KA treatment. To further investigate the effectiveness of Akt signaling, the phosphorylation of CTMP was examined. KA treatment induced an increased p-CTMP expression in the astrocytes of hippocampus at 1 day. LPS/IFN-γ-treatment on primary astrocytes promoted the p-CTMP was followed by phosphorylation of Akt and finally upregulation of CTMP and p-CREB. Time-dependent expression of p-CTMP, p-Akt, p-CREB, and CTMP indicate that LPS/IFN-γ-induced phosphorylation of CTMP can activate Akt/CREB signaling, whereas lately emerging enhancement of CTMP can inhibit it. These results suggest that elevation of CTMP in the astrocytes may suppress Akt activity and ultimately negatively affect the outcome of astrocyte activation (astroglisiois). Early time point enhancers of phosphorylation of CTMP and/or late time inhibitors specifically targeting CTMP may be beneficial in astrocyte activation for neuroprotection within treatment in neuroinflammatory conditions.

      • 2P-582 : Microwave-assisted process for adipic acid

        신나라,권소현,홍채환,전성환,김영규 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.0

        The growing concern of the depletion of fossil fuel reserves and increasing energy demands have encouraged the exploration of new processes for converting biomass into valuable chemicals and renewable fuel components. Among those biomass, cellulosic biomass has attracted much attention as a renewable and sustainable neutral and inexpensive feedstock. However, in order to use cellulosic biomass as an alternative to petro-based platform chemicals, normally consisting of hydrocarbons, the removal of oxygen-rich functional groups is prerequisite. Therefore, we have recently developed the microwave-assisted deoxydehydration reaction with metal catalyst. This synthetic process was sucessfully applied to the synthesis of the adipic acid which is one of the most important dicarboxylic acid, annually produced about 2.5 bilion kilograms and mainly to be used for the monomer of nylon from cellulosic biomass espeacially most abundant monosaccharide galactose.

        학급경영에 대한 국내 연구동향 분석(2000~2016)

        신나라,박수정 한국교육행정학회 2017 敎育行政學硏究 Vol.35 No.5

        The purpose of this study is to investigate the trends of classroom management research by collecting, sorting, and analyzing the academic articles and theses related to classroom management that have been published in Korea since 2000 and to suggest implications for future class management research in the basis of research results. To do this, we selected 166 classroom management related researches from 2000 to 2016, analyzed the research year, research topic, research methods, research subjects, researcher characteristics. And the characteristics of Korean classroom management research are derived. As a result of the analysis, the study related to class management appeared to be decreasing for 17 years, and it showed characteristics of practical nature such as analysis of actual condition and suggestion of class management. Quantitative research was the most studied method. Teachers and students were the most studied subjects, and the most research was done at elementary school level. Based on the results of this study, the characteristics of Korean classroom management research are derived, and the future activation, specialization, and theorization of classroom management research are suggested as implications. 이 연구는 2000년 이후 국내에서 발표된 학급경영에 대한 학술논문과 학위논문을 수집․선별하여 분석 준거에 따라 학급경영 관련 연구의 동향을 살펴보고, 분석 결과를 토대로 앞으로의 학급경영 연구에 시사점을 제시하는 것을 목적으로 하였다. 이를 위해 2000년 이후부터 2016년까지 발표된 학급경영 관련 연구 166편을 분석 대상으로 선정한 후, 연구연도, 연구주제, 연구방법, 연구대상, 연구자 특성에 대한 동향을 분석하였다. 연구동향 분석 결과, 최근 17년간 학급경영 관련 연구는 감소하는 추세를 보였고, 학급경영에 대한 실태분석이나 방안제시 등 실천적 성격의 연구가 주로 이루어졌으며, 연구방법으로는 양적연구가 가장 많이 수행되었다. 연구대상은 교사와 학생이 가장 많았고, 초등학교 급에서 가장 많은 연구가 이루어졌다. 이러한 연구결과를 바탕으로 국내 학급경영 연구의 특징을 도출하고, 추후 학급경영 연구의 시사점으로 활성화, 전문화, 이론화 등을 제시하였다.

      • 2P-425: AMF synthesis from fructose with alkylammonium halide

        신나라,김영규 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.0

        The depletion of fossil fuel reserves and increasing energy demands have encouraged new process development for converting biomass into valuable platform chemicals and renewable fuel components. 5-Hydroxymethylfurfural (HMF) is considered as one of the promising green platform chemicals. However, it has several problem realated with its production. Therefore, we`ve suggested 5-acetoxymethylfurfural (AMF), as an alternative to HMF. Less hydrohpilc acetoxymethyl group instead of hydroxy group on HMF makes it possible to practical separation and purification. Herein, we report another synthetic approach for 5-acetoxymethylfurfural (AMF) using alkylammonium halide as a reaction media.

      • 1P-435: Efficient one-pot synthesis of AMF from fructose

        신나라,김영규 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

        The depletion of fossil fuel reserves and increasing energy demands have encouraged new process development for converting biomass into valuable platform chemicals and renewable fuel components. Therefore, one of promising green platform chemical, we have suggested 5-acetoxymethylfurfural (AMF). Although, 5-hydroxymethylfurfural (HMF) is also considered as one of the promising green platform chemicals, AMF shows better physical properties derived less hydrophilic acetoxymethyl group wich make easy separation and purification possible. Therefore, with the importance of AMF in minde, we have newly devised efficient one-pot synthetic process of AMF from fructose using ionic liquid as a reaction media which could be simply resued several times.
