The wavelet transform is a popular tool for studying intermittent and localized phenomena in signals. In this study the wavelet transform of cutting force signals was conducted for the diagnosis of grinding conditions in grinding process. We used the Daubechies wavelet analyzing function to detect a sudden change in cutting signal level. STD11 workpiece was 85 times of machined pieces cut by the WA wheel and a tool dynamometer obtained cutting force signals. From the results of the wavelet transform, the obtained signals were divided into approximation terms and detailed terms. At dressing time, the approximation signals were slowly increased and 45 machined times noticed dressing time.

The indented geometry for rockwell hardness indenter has been configured by using Confocal Laser Scanning Microscopy (CLSM). For this purpose, the CLSM can be well suited to construct the three-dimensional indented volume from the indented surface by rockwell hardness tester. Furthermore, the height data of HEI(height encoded image) by CLSM must be acquired at first and converted to indented surface later. And the indented surface patterns enable us to predict the indenter shape and volume. This volume can be used to study the rockwell hardness model as a volume parameter. As a result, the technique performed in this study by combining the CLSM with compensation technique is an excellent one to obtain the geometries of indented surfaces over a wide range of surface resolution in a micro scale. And it can be used for micro volume calculation.

논문 : A. R. 에먼즈의 시의 비전: 포스트 모던과 생태적 접근

This paper focuses on A. R. Ammons`s vision of plants and fungi in the light of ecology and post-modernism. Ammons incorporated ecological and post-modern symbol of plants and fungi including lichen, moss, weed and grass into his poetry. He also recognizes values in the seemingly insignificant, and finds the hidden meanings of the common, the little, the small, the unnoticed, and the lowly, Ammons already disclosed the importance and values of these little things in the ecosystem of nature. While looking at what is lowly. he found the absolute and symbiotic relationship among the lowly, the hidden, and the unnoticed. In general, three kingdoms of classification consist of fungi, plants and animals in scientific terms. In this paper, I chose two kingdoms, which have the symbolic meanings. Ammons values the periphery and the dark over the beautiful, which man prefers. To deconstruct the opposites, he ventures to overturn the artificial or man-made hierarchy is indicated in that he valued those that are common, unnoticed, lowly, and insignificant in his poetry. This ecological vision of Ammons coincides with the deconstructive strategy of Derrida, in that they both resist aqainst the violent unity by which human reason controls in nature.

『네 사중주』와 종교적 행위: 동양철학과 가톨릭 전통의 관점에서

Eastern religious truths of Hinduism and Buddhism philosophy that T. S. Eliot was committed to influenced him deeply in that eastern religions try to become nirvana and brahman of the highest fulfilling stage. The teaching and truths of Bhagavad Gita and Buddhism aim at focusing on the unity of word and action describing negative way of emptying his desire, but want to identify and unify one to nature. Eliot’s conversion to Anglo Catholic also shows his religious identity of Catholic’s tradition pursuing sanctification unlike stressing the importance of protestant’s justification after the Reformation. Only his action such as “prayer, observance, discipline, thought” without desire and will to God is only religious and passive deed. Free action like meditation and contemplation is an religious deed of Catholic’s sanctification. After his remarriage he didn’t pay attention to worldly interest and pleasure in his all life, which accords with the negative way to reach purification of sin that is sanctification of Catholic tradition.

윤동주와 T. S. 엘리엇 그리고 A. R. 에먼즈 시의 죄의식

  T. S. Eliot, Dong Ju Yun, and A. R. Ammons lived in different country, culture, and generation, but were educated and raised under the influences of their christian family. Eliot divorced his wife not to meet her by hiring an attorney in spite of her resistance to a divorce by one-side agreement. Eliot repented his sins due to the consciousness of sin to her and his marriage life since her former wife died of mental disease alone in mental hospital. During the rest of his life he suffered from his deeds and was possessed of sin toward his dead wife. Eliot showed a sense of sin through the protagonist of his later poetic plays.   Dong Ju resisted God’s indifference to his country’s wretched reality as a christian and also regretted his decision to accept Japanese name to study to Japan. Dong Ju cherished Korean language and letter, but Japan didn’t allow Korean to speak and write them at that time. Dong Ju saw that his people had been tormented and exploited by Japanese colonial rule and tyranny. In his 1940 period’s poems, Dong Ju repented the sin of his doubt of God, and was ashamed of his decision to change his Korean name into Japanese name to go to Japan for studying.   A. R. Ammons was also a christian. His mother was Methodist, and his father was Baptist. He went to Sunday school of Fire-Baptized Pentecostal Church near his home and the family sometimes attended preaching on Sundays. Interview with David Lehman, Ammons said that he took religious spirit, whatever that is, from the Fire-Baptized Pentecostal. Ammons was obsessed with ecological sense of guilty that the earth has been ravaged and devastated by human desire and civilization. His innocent guilty may be something akin to but probably not the same thread as original sin. “The Damned” says that we, as people, are entangled with the network of humanity and nature, so we are not free from an obligation to others and feel the guilty from devastating the earth.

This research was done with help from 313 parents who have toddler and early children going to child care center in Seoul. Here are the results of the parents` recognition and requests about the early childhood physical activities in the child care center by using the "Self-Administration Method." In order to analyze the data, this study used a SPSSWIN ver. 10.0 program for statical analysis, and was completed using frequency analysis and one-way ANOVA analysis. The results of this study were as fallow. 1) The parents were aware of the necessity of the children`s physical activities and they were satisfied with the outcome of the new form of early childhood physical activities. 2) According to the result of the parents` recognition of the early children`s physical activities, they thought these activities were needed for the early children`s physical development and the most important thing was to improve this program and spread it out as much as possible. 3) The parents want the children to do these activities 2 or 3 times a week, 20 to 30 minutes at a time. Also they prefer to do this during the morning in the hall of the children educational department.

There are many dynamic properties in measured end-milling force. So, it is difficult to predict the real static property of end-milling force. Also the behavior of end-milling force is very complex to predict with the measured one. To extract the static property from measured force, it must be filtered and its problem is closely related to a de-noising one. Also this paper presents alternative de-noising method of end-milling force using wavelet filter bank, based on the wavelet transform and its inverse one. In this paper, by comparing the measured force and its wavelet filtered one, the fundamental end-milling force property after wavelet transform is well reviewed and analyzed. This result of wavelet filtering with filter bank shows the static force of end-milling which has severe dynamic properties occurring in entry and exit state of edge emersion into the workpiece.
