Ironpentacarbonyl에 의한 니트로벤젠의 환원반응에 PEG를 상이동 촉매로 사용한 결과 상온에서 90% 이상의 아닐린 수율을 얻을 수 있었다. 니트로벤젠의 반응속도는 PEG의 사슬길이와 결합점의 수에 의존하였으며 NaOH의 농도가 높고 용매의 극성이 커질수록 증가하였다. 그러나 아닐린의 수율은 NaOH농도가 2N일때 최대였으며 그 이상의 농도에서는 감소하였다 PEG phase transfer catalyzed reduction of nitrobenzene with $Fe(CO)_5$ afforded aniline up to over 50% yield al room temperature. The reaction rate of nitrobenzene was dependent on the chain length and number of binding sites of PEG, and it was increased with the concentration of NaOH and solvent polarity. But the yield of aniline was maximum) with 2N NaOH solution and it was decreased at higher concentrations.

γ-Al_2O_3, γ-Al_2O_3, SiO_2, TiO_2 등에 고정화된 폴리에틸렌글리콜을 Fe(CO)_5에 의한 니트로벤젠의 상온 환원반응에 상이동 촉매로 사용하였다. 고정화된 PEG의 몰수는 담체의 비표면적에 따라 증가하였고 PEG/γ-Al_2O_3가 가장 좋은 활성을 나타내었다. PEG의 사슬길이가 길고 NaOH농도가 높을수록 반응속도가 증가하였다. 적외선분광기를 이용하여 반응기구에 대한 고찰도 함께 실시하였으며 폴리에틸렌글리콜 상이동 촉매는 본 반응의 활성물질로 알려진 HFe(CO)_4,-이온의 생성과 이의 유기상으로의 이동을 촉진시키는 것으로 판단되었다. Immobilized polyethylene glycols onto metal oxides such as γ-A1_2O_3, α-Al_2O_3, SiO_2 and TiO_2 were used as phase transfer catalysts for the room temperature synthesis of aniline from nitrobenzene and ironpentacarbonyl. The amount of attached PEG molecules increased with specific surface area of metal oxides. Among the immobilized catalysts tested PEG/γ-Al_2O_3 showed the highest activity. The reaction rate increased with the chain length of PEG molecules and the aqueous NaOH concentration. Mechanistic study carried out using infrared spectrometer revealed that the role of PEG was to increase the formation of HFe(CO)_4^- ion, which is known as active species, and its movement from aqueous to organic phase.

Objectives : To assess clinical improvement and change in plasma brain-derived neurotrophic factor(BDNF) level after repetitive transcranial magnetic stimulation(rTMS) in patients with treatment-resistant schizophrenia. Methods : Seven patients with DSM-IV schizophrenia, who were proven to be treatment-resistant, were treated with 15 sessions of rTMS for three weeks as an adjuvant therapy to antipsychotic treatment. Clinical improvement and change in plasma BDNF level were measured after the treatment period. The symptom severity was assessed with the Positive and Negative Syndrome Scale(PANSS) and the Korean Version of Calgary Depression Scale for Schizophrenia(K-CDSS) at baseline and 7 days after the treatment. Plasma BDNF level was measured by enzyme-linked immunosorbent assay(ELISA) at baseline and 7 days after the treatment. Results : After the rTMS treatment, there was no significant improvement in PANSS total score(Z=-1.693, p=0.090) and no significant change in plasma BDNF was found(Z=-1.183, p=0.237). Negative correlations were found between percentage change in PANSS positive subscale score and duration of illness(rho=-0.991, N=7, p<0.0005, two-tailed), and PANSS negative subscale score at baseline and percentage change in plasma BDNF level(rho=-0.821, N=7, p=0.023, two-tailed). Conclusion : This preliminary study suggests that rTMS didn't make a significant change in clinical symptoms nor in plasma BDNF level in treatment-resistant schizophrenia. Percentage change in plasma BDNF, however, might be correlated with treatment resistance in schizophrenic patients. This is a pilot study with a small sample size, therefore, a further study with a larger sample size is needed.

피아노 교육에 있어서 피아노 교사들의 테크놀로지 도구 사용과 인식 조사
오소영 ( Oh¸ So Young ) 한국피아노교수법학회 2015 음악교수법연구 Vol.15 No.-
현대사회의 과학기술 발전은 교육 환경에 큰 변화를 가져다주었다. 이 변화는 인문, 과학, 예술 분야를 가리지 않고 테크놀로지를 융합한 학문 또는 테크놀로지를 활용한 학문으로 나타나고 있다. 따라서 본 연구를 통해 피아노 교육에 테크놀로지가 얼마나 적용되고 있는지 교사의 인식과 실제 활용 실태에 대해 알아보고자 한다. 연구자는 피아노 교사 295명에게 테크놀로지 도구 사용에 대한 인식, 사용하고 있는 도구의 종류, 학생의 연령과 학습수준에 따른 테크놀로지 도구의 종류 등을 설문조사하여 얻어낸 결과를 통계프로그램 SAS를 통해 분석하였다. 그 결과, 피아노 레슨에 테크놀로지 도구를 사용하고 있는 교사는 52.2%였고, 테크놀로지 도구 사용에 대해 긍정적으로 응답한 교사는 51.2%였다. 교사들은 연령과 학습수준을 통틀어 시청각 자료인 유튜브가 가장 적합하다고 생각하고 있으며, 실제로 가장 많이 쓰고 있는 도구는 CD플레이어였다. 그리고 교사의 테크놀로지 도구 사용에 대한 개선과 발전을 위해 테크놀로지 도구의 활용에 관한 교육과 정보의 제공이 필요한 것으로 나타났다. The development of science and technology in the contemporary society brought a considerable change in the environment of education. This change appears in various fields including the humanities, science, and art as a study converging technology or a study applying technology. Hence, this research aims to identify to what extent the technology is employed in the education of piano by exploring the teachers’ perception and current state of actual application. The survey was conducted targeting 295 piano teachers with regard to the perception on the use of technological devices, the types of devices in use, the type of technological devices according to the students’ ages and learning level, etc. and the findings were analyzed through SAS statistical software. The results show that 52.2% of the teachers are using the technological devices in their piano lessons and 51.2% replied positively about the use of technological devices. Concerning the age and the learning level as a whole, the teachers consider that the audio and visual material of YouTube is most appropriate while the most frequently used device was a CD player. In addition, it deemed necessary to provide education and information relevant to the application of technological devices in order to improve and develop the ways that teachers use technological devices.

Objectives:We developed the short form of the Mentalization Improvement Program for Adolescent-Community Model (MIPAdo-CM-S), based on the concept of the mentalization. Methods:The MIPAdo-CM was composed of 6 sessions and was applied to 133 students in the 1st grade of a middle school for six weeks during their regular school hours. After 6 weeks, we compared the endpoint changes of Adolescent Mental Problem Questionnaire-Revised (AMPQ-R), Emotional Empathy Test, Peer Aggression Scale, Peer Bullying Scale, School Adjustment Scale, Test Anxiety Inventory and Visual Analogue Scale between the subject and the control group. Results:On the Visual Analoge Scale, students in the trial classes reported an increased understanding and respect for others, as well as themselves. Conclusion:The efficacy of MIPAdo-CM was subjective improvement of understanding and respect for both others and themselves. To prove objective usefulness of this program, further studies should be administered in the form of long-term, regular and structured courses.
