리스트(Liszt)의 Transcendental E´tudes에 대한 小考

홍경자 기전여자대학 1994 論文集 Vol.14 No.-

Franz Liszt(1811∼1886) nab one of the most blilliant pianist and composer of the Romantic era and he powerfully encouraged the Romantic movement by conducting performance of many important new works. His cosmopolitan career was matched by the glamour works more than 600 composition including about 300 piano music. This study aims at exploring how he invented bib transcendental style in piano E´tudes and investigating some meanings and characteristics of 12 E´tudes d'exe´cution transcendante. Considering his formidable spirit of music invention originated from his own experiences, this thesis studies his autobiographical elements so that we may understand his postition as a pianist and composer as well. Originally published as simple exercises, 12 E´tudes were sealed up to the transcendental level of technique. ha they were consisted of lylical melodic qualities, many performers were in favor of playing them in the 19th century, Generally they have been misunderstood as music works for exercises, but his ardent frying to rewrite them three times indicates that they have hidden extraordinary meanings. Among them, Staccato, fast Tremolo, splend Scale, three or six doubled Arpeggio, and heavy succession of chords need high technique to play. On the contrary, some countermelody proves their diversities. Liszt's emphasis on the particular fingering based on strength and posture show that pianist can play these kinds of trenscendental piano works. In fact, it is very meaningful that his mode of expression had effected on new trends to Impressionism in the late 19th century and piano music in the 20th century.

There differed by the seed coat color showing 1.9% higher content in light gray than that of dark brown, which may suggest that the seed coat color could be used as a marker gene for breeding high protein varieties. Oil content of medium and late varieties in maturity showed higher as compared to early varieties, and appeared differences by seed coat color, and small seed varieties showed higher seed oil content than in large seed varieties by seed size. Linoleic and linolenic acid content of which major fatty acids in perilla seed were 74.4% in average of tested varieties. Fatty acid composition of perilla varieties were not significantly different by maturity, seed coat color and 1,000 seed weight. Oil content showed high positive correlation, with stearic and linolenic acids and negative correlation with linoleic acid.

Beethoven의 Piano Sonata op.57에 대한 고찰

홍경자 기전여자대학 1997 論文集 Vol.17 No.-

The primary goal of this paper is first to review on what composition method Beethoven composed and revived Appassionata Sonata as the cross road as well as in musicality and musical insight among most piano players. In the European musical history, Beethoven stressed on the romanticism focused on free emotional expression which is different from classicist focused on fixed form concept. In this point, Beethoven formed one thing important across the musical history through his famous works colored by classicism and romanticism. And this is characteristics. Moreover, every work contains his greatness and unlimited musicality featured by warm humanity and love far from rigid formalism. Based on this, he developed his peculiar Sonata style which is far from formalism famous in classicism. Appassionata Sonata expressed in 1804 when he was surrounded by unhappiness and hardship has his core features like attaca in chapter II, III and development coda which have free formalism. Appassionata Sonata demonstrates his rich emotional world through colorful transition dissonance, unceasing change of compass and dynamics. This paper points to be helpful to play more accurately and correctly among Beethoven layers.

홍은경,김경미 대한감각통합치료학회 2009 대한감각통합치료학회지 Vol.7 No.1

Objective : The purpose of the study is to find out how group sensory integrative (SI) intervention enhances play skill and social interaction of the children with sensory integration disorders. Method : Three children who were showing problems related in sensory integration received 12 SI intervention sessions. The Sensory Profile (SP) and The Social Maturity Scale (SMS) were accomplished by the subject’s primary caregiver. Test of Playfulness (ToP) and Peer Social Interactions Rating Scale (PSIRS) were utilized to investigate the children’s play skills and social interactions with their friends. Goal Attainment Scale (GAS) is applied to assess the children’s play skill, social interactions with peer, and sensory processing at each session. Data was collected before- and after the intervention and analyzed by the Wilcoxon matched-pair signed rank test with SPSS/WIN version 10.0 and Microsoft Excel. Results : The average scores of ToP, PSIRS, and SMS were increased after the sensory integrative intervention. However, there is no significant difference in the play skills and social interactions between data of pre-intervention and the one of post-intervention. The score of the GAS was frequently increased in terms of the play skills and sensory processing throughout the whole sessions. Conclusions : This study reveals a possibility of that the group sensory integrative intervention may affect not only sensory processing ability, but also play skills and social interactions of children experiencing difficulties of sensory processing. Future research should supplement limitations of this study regarding insufficient number of the subject and the short period of the experiment. 목적 : 본 연구는 감각처리장애아동에서 그룹 감각통합치료의 적용 후에 놀이와 또래와의 상호작용에 미치는 영향을 알아보기 위한 것이다. 연구방법 : 실험대상은 B지역에 거주하는 3-7세의 감각통합장애가 있는 아동 3명이었다. 평가는 그룹 감각통합치료 프로그램 전과 후에 감각처리능력과 놀이 기술, 그리고 또래와의 상호작용으로 나누어 실시하였다. 모를 통해 감각처리능력의 Sensory Profile과 또래와의 상호작용의 사회성숙도 검사를 하였고, 관찰을 통해 놀이 기술의 The Test of Playfulness와 또래와의 상호작용의 Peer Social Interactions Rating Scale을 평가하였다. 그룹 감각통합치료 프로그램 회기 동안에는 Goal Attainment Scale를 통해 감각처리능력과 놀이 기술, 그리고 또래와의 상호작용을 평가하였다. 그룹 감각통합치료 프로그램은 촉각, 전정감각, 고유수용성감각을 위주로 하여 구성하였고, 4주간 총 12회기 실시되었다. 연구결과는 SPSS/WIN 버전10.0과 엑셀을 사용하여 통계분석 하였다. 결과 : 그룹 감각통합치료 프로그램 적용 전과 후에 놀이기술과 또래와의 상호작용에서 통계적으로 유의한 차이는 보이지 않았다. 그룹 감각통합치료 프로그램 동안 평가한 GAS의 결과, 놀이기술과 감각처리에서 점차 향상된 모습을 보였다. 결론 : 본 연구 결과는 그룹 감각통합치료 프로그램이 감각통합장애아동에서 놀이기술과 또래와의 상호작용에 긍정적인 영향을 미친다고 명확하게 결론짓기에는 한계가 있다. 그러나 대상의 수와 실험기간을 늘려 치료를 적용한다면, 더 긍정적인 결과가 나올 것으로 예상된다.

The sources of information about methods of first arid were school (43.9%), mass media (15.6%), and self-study (10.5%). 30.0% of them never leaned the methods of first aid. 2.In the case of obtaining information on first aid through mass media, 58.2% of them got it from TV. 7.3% of them obtained it from magazines, while 5.8% of them got it from newspapers. According to their viewpoints of adequate time to teach the methods of first aid, 38.6% of them thought that the methods had to be taught in the primary school and 25.2% of them thought that they had to be taught in the kindergarten. 24.9% of them replied that the methods had to be taught in the middle school, while 11.3% of them replied that they had to be taught in the high school. 3.The points for knowledge of first aid were 98.29±20.91 on the basis of 150 points (65.5 points on the basis of 100 points). The points showed significant differences in the variables of sex, education level, numbers of siblings, parents' education level, and guardian's occupation.

열안정형 카테콜-O-메틸전이효소 유전자의 클로닝

홍경만,최용복,정갑용,지은정,장현신,박현,백문기 圓光大學校 醫科學硏究所 1998 圓光醫科學 Vol.14 No.2

Catechol-O-methyltransferase (COMT; EC 2.1.1.6) is the enzyme which catalyzes the transfer of methyl group to the catecholamine neurotransmitters from its methyl donor S-adenosyl-L-methionine. Partially purified COMT from rat liver has been used to measure the concentration of catecholamines in the blood through solvent extraction and thin layer chromatography after converting ^3H-methyl derivatives of catecholamines. To improve this inconvenient and fluctuating method, an attempt was made to use COMT gene for the measurement of catecholamines. Specific primers, COMT5P (5'-TGC TCA GAG GTG CTT TGA AG-3') and COMT3P (5'-GGA GCC GCA GAA GGT CA G-3'), were used to amplify COMT gene from human placenta cDNA library. The amplified COMT gene through 35 cycles of polymerase chain reaction was cloned into T-vector and the nucleotide sequences are determined by automatic sequencer. Human COMT has two common variants, a thermostable high activity form which has valine at amino acid 158 and a thermolabile low activity form which Has methionine at the same position. The cloned COMT gene in this study has both variants. Clone 4 and 5 have valine at amino acid 158 (guanine at nucleotide 472) and clone 1-3 have methionine at this site (adenine at nucleotide 472). In addition to this, there are other DNA polymorphisms in COMT gene at nucleotide 101, 102 (amino acid 34, a structural mutation cysteine/serine) and nucleotide 186 (a silent mutation). All of the clones have cysteine at amino acid 34 (guanine and adenine at nucleotides 101 and 102) and cytosine at nucleotide 186 except clone 3 which has thymine at this nucleotide. Clone 4 and 5 are thermostable high activity variants, suggesting being more useful for the measurement of catecholamines after expressing the gene.

[논문] trn L-trn F에 의한 한국 족도리풀속 식물 종 분류

성혜경,허만규,허홍욱 釜山大學校 師範大學 科學敎育硏究所 2011 科學敎育硏究報 Vol.38 No.-

Asarum consists low-growing herbs and is a genus in the Aristo-lochiaceae family with species found in the north temperate zones with most species in Asia. Any species with a highly structured variation pattern must show different distributions of phenotypic characteristics at different locations. I analysed intra- and interspecific phylogenic relationships within genus Asarum in Korea. I evaluated a representative sample of the fourteen taxa (eight Korean taxa and six obtained taxa from GenBank) with the trn L intron and the trn L - trn F spacer region of the chloroplast genome to estimate genetic relationships within genus Asarum. No variable positions were found within the trn L 5` exon and trn L 3` exon. Variable positions within the intron region were mostly distributed outside the structural elements required for intron processing, i.e., not within the first 140 bp at the 5` end and not within the 90 bp at the 3` end of the intron region. Within the spacer region, variable positions were evenly distributed. Alignment of the DNA sequences required adding numerous gaps. Sequence variation within the Asarum is mostly due to nucleotide substitutions, although several small indels and 20 inserts can be found. Another source of sequence divergence is length variation due to stretches of short repeats that occur at the intergenic spacer region ITS2 in all the Asarum. A + T content for eight Korean species of genus Asarum ranged between 64.3% and 64.6%. The base furtherance did not showed the significant difference to the by a total taxon. These values are similar to those (64.5%~67.1%) for the angiosperm alignments of the total trn L and trn F region. The main phylogenetic analysis revealed two distinct clades. The first clade includes ten species (eight Korean species, A. nipponicum, and A. tamaensis). The second clade includes four species (A. canadense , A. cautatum, A. chingchengense , and A. yakusimense). However, some internal nodes are poorly supported. Within Korean Asarum, four species were unsolved portions.
