Music listening is very crucial and the most fundamental activity to gain experience in that field. But it`s just a beginning stage to view music as a pleasant sound, and students should go beyond that by learning how to appreciate it. They naturally find it necessary to study knowledge on music while repeatedly listening to that. Internal and external knowledge on music as well as musical imagination make a big contribution to having a deeper understanding of music and enjoying its beauty better. Among different types of music to be appreciated, program music couldn`t be understood well by having some knowledge about music itself only, as there are some literary or artistic background in this type of music. Listeners should be aware of the specific context of program music to understand it and have sympathy for it. This study looks into the musical expression of the 「Peer Gynt Suites」 and seeks teaching methods about that by linking it to the poetic drama 「Peer Gynt」. The effort by this study made it clear that the attribution of the programmatic dimension of program music played a great role in understanding it. To successfully teach how to listen to program music, it`s required to pay attention to not only music itself but what`s described by it. And in order to stimulate students to enjoy listening to music on their own, More teaching methods should carefully be studied for motivating musical imagination and having sympathy for music.

본 연구는 타인평정 공감 척도를 개발하고 타당화하는 데 목적이 있다. 예비연구를 통해 개발된 15개의 예비 문항은 연구 1의 탐색적 요인분석을 통해, ‘공감의 시작’, ‘공감의 과정’, ‘공감의 결과’라는 세 개의 하위 요인으로 유목화되었다. 연구 2에서는 척도의 타당도를 확인하기 위하여 확인적 요인분석, 상관분석 및 판별분석이 시행되었다. 확인적 요인분석 결과 3요인 모형에 양호한 적합도를 나타내었고, 상관분석을 통해 진정성, 정서 명확성, 친밀감과는 정적 상관이, 불안 및 거부 애착과는 부적 상관이 있음을 확인함으로써 수렴 타당도가 검증되었다. 따라서 개발된 타인평정 공감 척도는 11개의 최종 문항과 세 개의 하위요인으로 구성된 척도로 보는 것이 타당한 것으로 확인되었다. 마지막으로 연구 결과에 근거하여 본 척도가 갖는 의의와 연구의 제한점 및 후속 연구의 방향성에 대해 논의하였다. The purpose of this study was to develop the Empathy Rating Scale by a third party and examine the validity of the scale. Based on the results of the pilot study, the study 1 focused on developing Empathy Rating Scale by a third party. From the exploratory factor analysis on a total of 15 preliminary items, three fators had been derived: ‘Beginning of empathy, ‘Process of empathy, ‘Result of empathy’. The study 2 identified its validity by confirmatory factor analysis, correlation analysis, and discriminant analysis. Those three factors indicated the reasonable fit index by confirmatory factor addition, this scale identified a significant positive relation with authenticity, emotional clarity, and intimacy. On the other hand, it indicated a negative relation with anxiety attachment and rejection attachment. Therefore, the results indicated that this scale on a total of 11 item has a reliable convergent validity. Finally, implication and limitation of this study were discussed in relation with future studies.

The redox flow battery (RFB) is a large-capacity energy storage equipment, and the vanadium redox flow cell is a typical RFB, but VRFB is expensive. Iron-chrome RFBs are economical because they use low-cost active materials, but their low performance is an urgent problem. One of the reasons for the low performance is the crossover of the active materials. In this study, the sulfonated Poly (ether ether ketone) (sPEEK) membrane, which is a hydrocarbon membrane, was used instead of the fluorine membrane to reduce the crossover of the active materials. The chromium ion permeability of the sPEEK membrane was 1.8× 10<sup>-6</sup> ㎠/min, which was about 1/33 of that of the Nafion membrane. Thus, it was shown that the use of the sPEEK membrane instead of the fluorine membrane could solve the high active material crossover problem. The activation energy of iron diffusion through the sPEEK membrane was 24.9 kJ/mol, which was about 66% of Nafion membrane. And that the e-PTFE support in the polymer membrane reduces the active material crossover through Iron-Chrome Redox Flow Battery (ICRFB).

상담에서 내담자들이 나타내는 주요 정서들의 비언어적인 음성 정보가 어떤 특성들을 지니는지를 확인하기 위해 40개의 상담 사례로부터 총 150회기의 상담 내용이 담긴 독음 자료를 수집하여 이로부터 기쁨, 슬픔, 화, 두려움의 네 가지 주요 정서가 뚜렷하다고 평가된 22개 음성을 추출하였다. 이 22개의 음성들 각각에 대해 높낮이 , 높낮이 변화, 빠르기, 강약, 발음의 분명도, 말끝의 형태, 쾌-불쾌 정도, 흥분 정도 등의 음성 지표가 얼마나 나타났는지를 42명의 평정자들로 하여금 평가하도록 한 후, 각 음성 지표를 판별 변인으로 한 판별함수 분석을 실시하였다. 그 결과, 강약, 홍분 정도, 높낮이 , 빠르기 , 높낮이 변화, 쾌-불쾌 정도, 발음의 분명도 등 7개의 음성 지표들이 판별 변인으로 투입되었고, 실제 정서와 판별 정서간의 정확 판별률은 73.9%로 높게 나왔다. 이는 7 개의 음성 지표들을 사용하여 기쁨, 슬픔, 화, 두려움 등의 주요정서를 판별하는 것이 가능할 뿐더러, 상당히 그 결과 또한 신뢰할 만하다는 것을 나타낸다. 판별함수 분석에서 나타난 결과를 토대로 각 정서별 음성 정보 특성을 기술하였다 마지막으로 본 연구의 시사점과 제한점을 논의하였고, 그리고 추후 연구를 위한 제언을 제시하였다.

Focusing on benzene, a representative of volatile organic materials resulting from oil pollution, this paper studies the effects of photocatalytic oxidation and photo-sensitized ions, when TiO₂photocatalyst is added to photo-sensitized ions ; persulfate, sulfate, nitrate, nitrite, and chloride ion. This study found that the benzene in aqueous solution was efficiently removed through photocatalytic oxidation. In case of photocatalyst- sensitized-oxidation that the wavelength less than 330㎚ was intercepted by the use of Pyrex filter, an addition of persulfate ion, and sulfate ion showed some elevation of dissolution rate of benzene, whereas an addition of nitrite ion and chloride ion lowered the dissolution rate of benzene. The coexistence of persulfate ion and nitrate ion showed the same dissolution rate tendency as the result of photocatalytic oxidation of benzene. However, the coexistence of nitrite ion lowered the dissolution of benzene.
