In spite of the importance of the three pedals in piano playing, there are only few studies done on this subject. The reasons can be summed up as the followings: 1) the absence of the clear descriptions on the pedal techniques. 2) a lack of interest in the pedal techniques among the piano population. 3) the difficulties in explaining the pedal techniques. But the significant improvements made on the instrument itself since its invention, combined with the considerable expansion of the concepts of melody, harmony, rhythm, texture, etc. in piano literature, demand a greater variety of sounds from the modern piano. The author believes that the three pedals have very important roles in this world of modern piano playing. In this study, the basic concept of pedaling, various terminologies which relate to the pedals, various pedal techniques and how these pedal techniques are applied in performance in order to express individuality are explained. Also, several helpful comments on the subject of the pedaling given by recognized pianists and piano teachers are included at the end of this study.

Effects of dyeing temperature, dyeing time, concentration of sodium hydrosulfite, and addition of anti-overreduction agent, on the reduction behaviors of the two anthraquinone vat dyes were investigated. In the case of Indanthrene Blue BC (C.I. Vat Blue 6) the overreduction appeared apparently as the dyeing temperature and the amount of reducing agent increased. Addition of the anti-overreduction agent such as glucose depressed the occurrence of overreduction of Indanthrene Blue BC to some extent. Reduction behavior of indanthrne Blue CLF(C.I. Vat Blue 66) was not affected by the dyeing temperature and the amount of sodium hydrosulfite, suggesting that this dyestuff was quite stable in reductive conditions due to the strong intramolecular hydrogen bond between NH and O atom of the carbonyl group.

The genetically determined ability to metabolize debrisoquine (DBR) is related to risk of lung cancer and DBR hydroxylation exhibits wide inter-individual variation. In this study, 100 korean adults were tested for their ability to metabolize DBR. The DBR metabolic phenotype were determined by metabolic ratio (MR, DBR / 4-HDBR) which is the percent dose excreted as unchanged DBR divided by the percent dose excreted as 4-hydroxyebrisoquine(4-HDBR) in a aliquot of an eight hour urine sample, after 10mg DBR test dose administration. Analysis was performed on a capillary gas chromatograph fitted with electron capture detector. The results were as follows; 1 Geometric mean of DBR MR was 0.32 in male,0.27 in female,0.30 in total and the distribution of log (MR) was seemed to follow normal distribution. 2. Metabolic ratio of DBR was higher in non-smoker and non-drinker than in smoker and drinker without any statistically significant difference. 3. None of personal factors was significantly related to DBR MR except age. 4. The DBR metabolic phenotype was extensive metabolizer(EM) 93, intermediate metabolizer(IM) 7 by traditional method and EM 98, IM 3 by Caporaso's method. The poor metabolizer (PM) phenotype was not found by either method. 5. Maximal expected PM phenotype was 0.36% by traditional method and 0.04% by Caporaso's method.

Variations of the concentration of sodium hydrosulfite used as a reducing agent in vat dyeing in aqueous solution and in dyeing solution, and during dyeing were investigated. Concentrations of sodium hydrosulfite in all cases were considerably affected by the amount of air in dyeing machine. The concentration of the reducing agent in aqueous solution under closed system decreased with temperature and time, but that under the purge of nitrogen gas did not change with temperature and time, but that under the purge of nitrogen gas did not change with temperature, time and the amount of sodium hydroxide. The decomposition behaviors of the reducing agent in dyeing solution and during dyeing were similar to those in the aqueous solution. The concentration of sodium hydrosulfite in dyeing solution decreased with increase in the amount of dye, the leuco potential of dye and the number of keto groups in dye molecule.

식민지 조선의 자동차 보급 추이와 시장 변화

이명학 고려대학교 민족문화연구원 2024 민족문화연구 Vol.105 No.-

이 글은 일제시기 자동차의 보급 추이와 시장 구조를 분석했다. 1911년 2대에서 출발한 자동차는 1942년 12,559대로 급증했다. 이를 견인한 부문은 상용차였다. 민족별로는 일본인이 주도적인 위치에 있었다. 조선인은 상용차 영역에서 30-40%대를 차지했지만, 자가용에서는 비중이 미약했다. 자동차가 격증한 데에는 일반적인 조건 이외에 두 가지의 요인이 기여를 했다. 하나는 도로 환경의 개선이었고 다른 하나는 상품성의 향상이었다. 대대적인 정비 사업을 통해 주요 도로는 자동차의 통행이 가능할 정도로 넓어졌다. 1920년대 중반 일본에 포드와 GM의 조립 공장이 건설되면서 자동차 가격은 이전 대비 50% 이하로 내려갔다. 한편 조선의 자동차 공업은 유치한 수준을 벗어나지 못했다. 1941년에 가서야 조립 공장이 세워졌지만, 이마저도 물자난으로 제대로 운영되지 못했다. 이에 조선의 거리는 수입차의 독무대가 되었다. 그중에서도 포드와 GM은 자동차 시장을 양분했다. 그러나 1930년대 후반에는 판도가 급변했다. 자동차의 국산화와 외국계 기업의 자동차 퇴출을 목표로 한 전시 통제 정책이 강력히 추진된 결과 포드와 GM의 신규 차량은 시장에서 자취를 감추었다. 빈자리는 일본 자동차로 채워졌다. 해방 당시 일본 자동차의 점유율은 최대 50%까지 치솟았다. This article analyzes the trend of automobile penetration and market structure during the Japanese rule. The number of automobiles soared from 2 in 1911 to 12,559 in 1942. One segment that drove this was commercial vehicles. By ethnicity, the Japanese were in the lead. Koreans accounted for between 30 and 40 percent of commercial vehicles, but were underrepresented in private cars. In addition to the general conditions, two factors contributed to the surge in cars. One was the improvement of road conditions and the other was the improvement of productivity. Through extensive maintenance, conventional roads were widened to accommodate automobiles. With the construction of Ford and GM assembly plants in Japan in the mid-1920s, automobile prices dropped to less than 50% of what they had been before. On the other hand, the automobile industry in Korea was still in its infancy. It wasn't until 1941 that an assembly plant was built, but even then, it didn't operate properly due to shortages. As a result, the streets of colonized Korea were dominated by imported cars. Ford and GM dominated the market, but by the late 1930s, the game had changed. As a result of wartime control policies aimed at localizing automobiles and driving foreign companies out of the country, Ford and GM's cars disappeared from the market. Japanese cars filled the void. By the time of liberation, the share of Japanese cars had soared up to 50%.

1920-30년대 불량주택지구 개선사업의 구상과 변질

이명학 고려대학교 민족문화연구원 2019 민족문화연구 Vol.82 No.-

This study examined the developmental processes and characteristics of projects to improve substandard residential complexes. The Japanese Government-General of Korea planned a fundamental solution for both the illegality and harmfulness of substandard houses with the appointment of Shiro Ikegami. Major cities around the nation carried out a project of improving substandard residential complexes, which was to provide clean and affordable rental houses through political conflicts. This project, however, fell apart when the new top management held office with no interest in the residential environment of poor people. Instead, the colonial authority decided to concentrate substandard houses in suburbs. The project of building a complex for the poor settled down as a typical measure in the areas where an urban district plan was carried out. This project was, however, distant from the improvement of poor people's residential environment even though it might have been beneficial to local governments whose main purpose was to ensure smooth development. Not only was the site far from the labor market, but it also had poor public facilities with no supports for housing renovation. In the end, the measure of the colonial authority merely expanded and reproduced "slums" where the residential environment deteriorated even further. The dwellings of poor people in Joseon were not the objects of social inclusion and improvement but the obstacles that should be eliminated for development. 이 글은 불량주택지구 개선사업의 전개과정과 특징을 살펴보았다. 이케가미 시로(池 上四郞)의 부임과 함께 조선총독부는 불량주택의 위법성과 유해성을 동시에 해결하는근본적인 대책을 기획했다. 주요 도시에서는 정치적 갈등을 거쳐 청결하고 저렴한 임대주택을 공급하는 불량주택지구 개선사업이 추진되었다. 그러나 이 사업은 빈민의 거주환경에 무관심한 수뇌부가 들어서면서 수포로 돌아갔다. 대신 식민권력은 불량주택을 변두리에 집결시키는 사업을 시행했다. 세민지구 조성사업은 시가지계획이 진행되는 곳의 전형적인 대책으로 자리를 잡았다. 그러나 이 사업은 원활한 개발을 주목적으로 하는 지방단체에게는 유익했을지언정 빈민의 거주환경 개선과는 거리가 멀었다. 노동시장과 동떨어진 곳에 부지가 위치했을 뿐만 아니라주택 개량을 위한 지원이 전혀 없고 공동시설이 미비했기 때문이다. 결국 식민권력이 시행한 대책은 거주환경이 더욱 악화된 ‘슬럼지구’의 확대재생산에 불과했다. 조선인 빈민의 주거는 사회적 포섭과 개량의 대상이 아니라 어디까지나제거해야 할 개발의 장애물이었던 것이다.

모더니티와 모더니즘 문학 -1930년대를 중심으로

이명학 단국대학교 한국문화기술연구소 2008 한국문화기술 Vol.6 No.-

本論文主要考察了近代以及近代性和現代主義文學槪念(定義), 也談論了其槪念的相互關系, 最后談論了現代主義文學在韓國文學中的特征。 近代以及近代性這個槪念在韓國文學中仍然有爭議, 與타關聯的現代主義槪念的理解也如此。 近代以及近代性, 現代主義槪念是不是自生的。 1930年代的韓國文學中出現的現代主義思潮是通過日本接受的西歐的東西。 現代主義思潮在西歐先興起, 西歐的現代主義文學具有非常濃厚的文明批判意識。 而韓國的現代主義文學把西歐的文明作爲追求的對象, 因此不像西歐的現代主義文學缺乏文明批判意識。 但是殖民地下的知識分子的彷徨和苦悶的描寫, 富有特定時代的氣息。 這成爲韓國的現代主義文學的特征。
