This article aims to investigate what Yu Giljun, a pioneer of Korean capitalist spirit, thought of the transition to the modern age. The main objects of analysis include his business activities, participation in workers' organization like evening class meeting, and the analysis of the Reading Book of Worker's Evening Class. The period of analyzing represents the year 1907, when he came home to Korea, to 1910 of Korea becoming a Japanese colony. His business activities and view of labor are as follows. First, his economic thought can be summarized as 'the path to capitalism based on landed modernization line'. His concrete business activities like the establishment of companies and the participation in economic organizations after coming home to Korea in 1907 can be regarded as the practice resulting from his view of the modern age. However, his position pursuing the capitalist modernization through the upbringing of bourgeois class and the increase of productivity was limitary in terms of the then political reality. We can appreciate his economic enlightening activities and effort to increase industrial capital, though. Secondly, it is remarkable that he took an active part in worker's organization. His direct participation in worker's organization formed a part of making 'the modern main group' by drawing working classes into landed modernization line. However, it included his own political, economical intention, too. Thirdly, the Reading Book of Worker's Evening Class by Yu Giljun aimed to apply his national education theory based on landed modernization line to working classes. It was natural in terms of his view of modern age for him to praise labor, try to present new vocational ethic view, and emphasize the ethics of labor. His labor view in favor of capitalists and his inciting workers to form mutual aid organization shows his view point well. New ethics of labor that he tried to present shows both significance and limitation appearing in the process of shifting from subjects to new people.

In the sonochemical reaction, the solid of sludge can be disintegrated and solubilized by hydromechanical shear force, pyrolysis, and free radical attack during the cavitation. This study was performed to evaluate the feasibility of ultrasonically treated raw sludge as carbon source for biological denitrification and phosphate release. A 530W ultrasonic processor with a frequency of 40kHz was used to sonicated the raw sludge from wastewater plant. To find the optimal SCODcr buildup condition. we examined the effects of solid concentration of sludge, ultrasonic density, irradiation time, aeration, and pH on TSS and SCODcr concentration during the ultrasonic irradiation on raw sludge. Ultrasonic irradiation was applied to raw sludges with different solid contents (1, 3, and 5%.) and different ultrasonic density (0.04, 0.06, and 0.12W/rnl). Ultrasonic irradiation showed a rapid and significant decrease in TSS concentration in raw sludge. The kinetic of the degradation rates of TSS by ultrasonic irradiation was satisfactorily described by a pseudo-first order reaction. The degradation efficiency of solid in raw sludges were over 60%, and ranged from 3.0 to 7.2 ㎎TSS/W . hr. Also the SCODcr yields of 2.1 -3.2 ㎎SCODcr/W·hr in this study were observed and depended strongly on ultrasonic density. With aeration. the sonication on raw sludge further increased SCODcr concentration. However, it is less effective to irradiate ultrasonically the pH-adiusted raw sludge. The optimal operating condition to increase soluble organics was to sonicate the sludge with 5% TSS under the ultrasonic density of 0.12W/ml and showed the yield of 3.2 ㎎SCODcr/W . hr. Also the sonicated sludges with different sonication time(ranging between 0-9hrs) under 0.I2W/ml were fed into the batch reactors as carbon source. Those ones had a strong influence on the denitrification rate and the P-release concentration. The specific denitrification rates of batch reactors varied within a range from 0.46 to 1.97 mgNO₃-N/gVSS·hr, and 1.33-1.85 gSCODCr consumed/gNO₃-N removed was observed. The concentration of phosphate which was released by poly P microbes were in the range of 0-4.75㎎/L. and 0.55-1.22gPO₄-P released /gSCODcr consumed was showed. The economically most competitive sludge as carbon source was one under 3hr sonication time to accomplish the high denitrification rate and the P-release concentration. Therefore, the ultrasonically treated sludge can be another carbon source for BNR process.

다량의 무리 말뚝에 대한 매트릭스 해석

본 연구에서, Bowle에 의해 제안된 유한 요소 해석은 얼마나 많은 힘과 모멘트가 그룹에서 각 파일에 발생하는지를 구하기 위해 사용되고 이러한 값들은 그룹 파일 설계에 사용된다. 파일 그룹 해석을 위한 몇 개의 해석 방법이 있다. Reese와 Saul은 매우 비슷한 방법을 사용한다. Saul은 XZ평면에 파일 두부력의 하나를 놓고 분리한 마트릭스를 사용하는 것에 의해서 파일력 인자를 고려한다. Reese at al.(1970)은 XY 평면에 하나의 파일 두부력을 놓고 파일 캡 모멘트 저항에 있어서 파일 두부력의 분포를 직접적으로 고려한다. 본 연구에서는 Reese at al.(1970)의 해석 방법을 사용하였다. 파일 그룹 해석에 있어서 임의 마트릭스법에 포함된 중요한 두 가지 차이점은 코싸인 방향의 결정과 파일 두부 강성을 결정하는 방법이다. In this study, The finite element solution that Bowles assumed is used to check out how much forces and moments are happened on each pile in group and theses values can be used to design group pile. There are some solutions that is for analysis pile groups. Reese and Saul use very similar method. Saul places one of the pile-head forces in the XZ plane and considers the pile force components by using a separate matrix. Resses et al.(1970) place one pile-head force in the XY plane and directly consider the contribution of pile-head forces in resisting pile-cap moments. The Reese et al.(1970) solution is essentially the same as the method in this study. Two of the major differences involved in any matrix method of pile-group analysis are the definition of the direction cosines and the method of defining the pile-head stiffness.

Shear connector in composite structures which is used to connect steel and concrete. resists a n external force and prevents on the contact plane. Shear connector, made of stud and bolt, was used for this study. This study used push-out test and numerical analysis to analyze statical behavior of the shear connector. These sults were compared to the design standards of various nations to provide preliminary data for the study of shear connector.
