The effects of antimigrant on dye migration during drying in continuous dyeing of Polyester/Cotton blended fabrics were studied. C.I. Disperse blue 125 and Na-alginate were used as dyestuff and antimigrant, respetively. In order to investigate the effects, critical moisture content and wicking property were measured and the capillary radius through the water concentration gradient of fabrics was also determined. The results showed that dye migration during drying was affected by viscosity of dye liquor and the increase of the Na-alginate concentration resulted in the decrease of radius of the most frequently occurring capillaries and max. capacity of the continuous capillaries.

Mini-Mill process has been recently in operation at Pohang steel company, which enables more flexible steel coil production on customer demands. The effects of process parameters in Mini-Mill process need to be analyzed not only to make the process stable but also to improve product quality. This work aims to develop a regression model of Mini-Mill process using accumulated product data such that the process parameter effects on product tensile strength may be analyzed. The analysis shows that tensile strength is influenced mainly by the amount of components such as carbon, manganese, silicon, and sulfur. The effect of temperature is shown to be small. It is concluded that control of the components is much more responsible for both meeting the target and reducing the variation of the product tensile strength. Heat treatment is more useful in compensating tensile strength variations due to thickness differences and improving workability and other quality characteristics. More work is necessary for establishing regression expressions of the process that is reliable and accurate enough to dispense with the off-line inspection of the product tensile strength.

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.

일제시기 재정통계의 활용과 해석의 지형

이명학 ( Lee Myoung Hak ) 고려대학교 민족문화연구원 2017 民族文化硏究 Vol.75 No.-

이 글은 재정통계를 활용한 지적 실천의 지형과 의미를 분석했다. 첫째, 조선총독부는 `선정(善政)`을 과시했다. 관료는 외형적 변화에 초점을 맞추어 대한제국재정의 낙후성과 조선재정의 양적 팽창을 강조하고 재정 운영의 `자기개혁성`을 드러냈다. 둘째, 오다 타다오(小田忠夫)는 내재적 관점에서 권력 수행의 한계와 불공평한 과세체계를 비판하는 동시에 증징 이전에 조선인의 담세력 배양이 선결되어야 한다고 역설했다. 그러나 그는 재정 문제를 개선의 차원으로 한정하고 식민 지배에 대한 본질적 비판을 도외시했다. 셋째, 조선인의 세출통계 해석에는 이견이 없었다. 원활한 지배와 식민지자본주의의 주조가 조선재정의 존재 이유라는 명확한 인식 아래에서 조선인은 세출 운영에 만연한 민족 차별을 주장했다. 그러나 세입통계의 해석에는 두 가지 기획이 존재했다. 하나는 조세체계의 민족적 불공평과 민족별 생활수준 격차를 증명하여 조선인과 괴리된 경제 성장을 비판하는 것이었다. 다른 하나는 세입체계가 농민을 반봉건적 생산관계에 옭아매는 결정적인 기제라는 점을 논증하는 것이었다. This study analyzed the scope and significance of intellectual practices based on government finance statistics. First, the Japanese colonial government displayed a `wise rule`. Officials employed description schemes that are specialized for superficial alterations to emphasize the stagnancy of the Korean empire and the quantitative expansion of Joseon`s finance. Moreover, they highlighted the self-reforming nature of the system and operations. In addition, Tadao Oda criticized the limitations of the authorities and the unfairness of the taxation system from an internal perspective. He also asserted that the taxable capacity of Koreans requirement improvements before taxes could be collected. However, Oda limited financial issues to systematic concerns, and neglected their relationship to colonialism. Lastly, the present study found no difference of opinion in the interpretation of expenditure statistics for Koreans. Racial discrimination was evident in the management of expenditures under the defined understanding that the existence of Joseon finance is due to the effective control and the framework of colonial capitalism. However, there were two plans concerning the interpretation of expenditure statistics. The first plan was to prove the racial unfairness of the taxation system as well as the gap in living standards by race and to criticize the imbalanced economic growth. The second was to show that the taxation system was the main mechanism binding farmers to anti-feudalistic production.

본 논문은 객체(Entity) 간의 관계(Relation)를 예측하는 링크 예측(Link Prediction) 과업을 위한 모델을 학습하는 방법론에 관하여 서술하였다. 링크 예측 과업의 학습을 위해서는 객체-관계-객체(Entity-Relation-Entity)로 이루어진 지식기반 삼중 데이터 집합이 필요하다. 그러나 지식기반 삼중데이터 집합의 수가 적으므로, 우리는 문서 형식의 데이터 집합으로부터 지식기반 삼중 데이터 집합을 추출해 새로운 데이터 집합을 만들어 이 문제를 해결하였다. 그리고 추출된 데이터 집합이 링크 예측 모델을 학습할 수 있는지 알아보기 위해 링크 예측 과업에서 사용하는 대표적 모델인 HAKE(Hierarchy-Aware Knowledge Graph Embedding)와 AcrE(Atrous Convolution and Residual Learning)의 학습을 진행해 보았고 그 결과 HAKE 모델과 AcrE 모델에서 각기 0.4328과 0.4812의 정확도를 보였다.

1920년대 조선총독부의 주택정책과 공영주택의 관사 전용

이명학(Lee, Myoung-Hak) 고려사학회 2021 한국사학보 Vol.- No.83

1910년대 후반 이후 불안정한 주거는 중요한 사회문제로 부상했다. 피지배민의 생계를 관리하는 새로운 통치 기술을 도입한 조선총독부는 그 일환으로 주택정책을 실시했다. 그러나 시장의 자정 능력에 의존하는 것이 주택정책의 본질이었던 탓에 시장질서의 근본적인 재편성은 이루어지지 않았고 단지 임시적인 조치로 공영주택의 보급이 시행되었다. 1920년대 유일한 주택정책으로 등장한 직접 공급은 다음과 같은 특징을 지녔다. 먼저 양적인 측면에서 공영주택은 미미한 수준에 머물렀다. 1928년 현재 공영주택은 341호에 불과했다. 공익단체의 운영 분까지 합한 규모는 대만의 10%, 일본의 7.56%였다. 다음으로 질적인 측면에서 공영주택은 편향성이 두드러졌다. 민족적인 층위에서 공영주택은 일본인 위주로 운영이 되었다. 일본인용은 조선인용보다 최대 3.85배 많았다. 계층적인 측면에서 가난한 조선인이 사용할 수 있는 곳은 전체의 26.98%에 지나지 않았다. 마지막으로 입주자와 관련하여 공영주택은 또 다른 관사로 기능했다. 대부분의 공영주택은 처음부터 총독부 소속 일본인 관리의 주거공간으로 기획이 되었고 그렇지 않은 곳도 관리를 우선적으로 선발했다. In Korea, the unstable housing environment emerged as a critical social issue in the latter half of the 1910s. The colonial power introduced a new ruling technology of managing the livelihood of people under their rule and implemented a housing policy as part of it. As the essence of housing policies was to depend on the self-purification capacity of the market, however, there was no fundamental reorganization of the market order with only public housing provided as a temporary measure. Direct supply, which appeared as the only housing policy of the 1920s, had the following characteristics: first, public housing remained at a trivial level in terms of quantity. There were only 341 units of public housing space in 1928. Even when they were combined with the units managed by public organizations, the total quantity accounted for 10% of Taiwan and 7.56% of Japan. Then, the public housing showed a prominent inclination in terms of quality. In Joseon, public housing was managed mainly focused on Japanese people, who were 3.85 times more than Joseon people in public housing according to the ethnic layer criterion. In terms of social class, poor Joseon people were able to use only 26.98% of the entire public housing. Finally, public housing functioned as official residence for government officials in terms of occupants. Most units of public housing were planned as quarters for Japanese government officials at Japanese Government General of Korea, provincial offices and Bu offices from the beginning. Even those which were not planned for them picked out government officials first.

총동원체제기(1940~1945년) 경성부 세입구조(歲入構造)의 변화와 부세(府稅)확대

이명학 ( Lee Myoung Hak ) 역사문제연구소 2012 역사문제연구 Vol.16 No.2

Since the year 1940, the size of the Gyeong`seong-bu city authorities` finance jumped 2.68 times in appearance, and 1.9 times essentially. There were several characteristic methods in securing financial supplies displayed by the Gyeong`seong-bu authorities in expanding its finance. First, since 1940 Joseon was enlisted in the Japanese imperial authorities` plan of `enterprise accumulation,` and the quota of national debts increased. In the meantime, each of the financial agencies started to purchase both national and personal loans, and the issuing of Bu Bonds(府 債), the former primary source of income for the Bu authorities, was reduced. Supports from senior administrative bodies remained minimal. Second, the Gyeong`seong-bu authorities raised the user expenses and fees every year, regardless of the Bu`s needed amount of expense, or the income level of the general users, or the very nature of utilized facilities. And since 1940, the Bu authorities levied a new user fee upon the Land Readjustment project. Third, the Gyeong`seong-bu authorities revised the supertax standard of assessment, raised the general tax rate, newly created a traffic tax which was a special, indirect excise tax, and double-levied object taxes. By doing so, the Bu authorities attacked the `haves` class with concentrated taxation, and targeted at the same time the general population with indiscriminate taxes. As a result, the previous primary source of income for the Gyeongseong-bu body was replaced by the `Bu tax` since 1940. Yet there was a problem. The Joseon Bu units` “legally dictated” primary source of income was not the `Bu tax.` It was rather the other kinds of user expenses, fees or property-generated other forms of income. Then why was there a discrepancy between the law and reality? Unlike major cities in Japan, which publicly managed electricity, gas and water as they were all crucial commodities in the people`s lives, the Gyeong`seong- bu in Joseon only managed water. In Japan, the overall [`social property`] area publicly managed by the city authorities was wide and therefore so was the revenue composed of user expenses and fees. But Gyeong`seong- bu in Joseon lacked such administrative publicness, and failed to utilize user expenses and fees as the primary source of income.
