It is still hard to measure the strain distribution over entire surface of a medium or large-size stamped part even by using an automated strain measurement system. Several methods which enable to enlarge the measurement range without losing accuracy and precision are suggested in this study, The superposition of images having different high-lightened or damaged part each other results in an enhanced image. A new method for constructing the element connectivity from a line-thinned image makes it possible to identify up to 1,000 elements. And the geometry assembling algorithm is proved very efficient in which the whole area to be measured is divided into several parts ; the coordinate transformation between every two adjacent parts is obtained from the concept of the least square error ; and the 3-D shape or strain distribution over the whole surface is assembled,

In general, when geometry and current distribution have a periodic or symmetric property, the analysis of a part model is sufficient to represent that of a whole model by using the periodic boundary condition. It is impossible, however, to apply the periodic boundary condition when the current distribution is not symmetric even if the geometry of the model is symmetric. In this paper, a novel technique to resolve this problem is proposed. Even when the geometry is symmetric and the current distribution is not, the proposed method enables that calculation time for a whole model is reduced to that for a part model. The proposed method is applied to a deflection yoke (DY), and validness and efficiency of the method are verified.

In this study, we select and analyze the slang that is represented in Elistratov's "Dictionary of Russian slang". Through the above analysis, some conclusions were drawn as follows: First, as a social and psychological phenomenon appears universal in all languages, the study of slang generates strict criteria for the analysis. Unlike literary language, listed in the dictionary slang expressions can become obsolete for their short period of usage by native speakers. Therefore, in the following research of the actual data, we have to validate words targeted for analysis. Second, as the result of the analysis it is metaphor for the most part studied rather than metonymy. The semantic derivations as a result of metonymy are used very frequently in real life. But in this study we mainly analyze words, therefore the number of words was less in metonymy than was expected. Third, the basic types of metaphor are appeared as similarity by form, function, and location, and there are varieties of intervening of subjectivity in similarity of emotional impression. Fourth, the metonymy is divided into three cases: the part meaning the whole, the whole meaning the part, and some thing meaning the reality of where it exists. Fifth, not only literary language, but also slang as the 'transitional process' is the most active way of development of new meanings, and there are two methods to transfer main meaning to second meaning.

목 적 : 현재 전뇌 방사선 치료 시 두부의 고정을 위하여 Optimold가 사용되고 있다. 하지만 Optimold로 인한 산란선에 의해 피부선량이 약 22% 증가하게 된다. 백내장을 일으키는 최소선량이 2 Gy 이므로 특히 수정체에서는 영향이 크다고 볼 수 있다. 이에 전뇌 방사선 치료 시 Optimold 안구 부분의 유무에 따른 수정체에 흡수되는 선량을 비교평가 하고자 한다. 대상 및 방법 : 안구 부분의 Optimold의 유무에 따른 수정체에 흡수되는 선량을 비교평가 하고자 인체모형팬텀(Anderson Rando Phantom, USA)의 수정체 부분에 5mm bolus를 올려 Optimold mask를 만들었다. 모의치료 시 수정체의 선량측정을 위해 bolus 밑에 GAFCHROMIC EBT3 film을 위치시켜 모의치료를 진행하고 전산화치료계획시스템(Pinnacle, PHILIPS, USA)을 통해 치료계획을 수립한 후 치료도 동일하게 진행하여 3회 반복측정 하였다. 안구 부분의 Optimold mask를 제거하고 위와 동일한 방법으로 측정하였다. 디지털 평판 스캐너(Expression 10000XL, EPSON, USA)를 이용하여 film을 스캔한 후 선량을 측정하여 안구 부분의 Optimold mask의 유무에 따른 선량을 비교평가 하였다. 결 과 : 안구 부분의 Optimold mask가 있을 때 모의치료 시 $10.2cGy{\pm}1.5$, 치료 시 $24.8cGy{\pm}2.7$, 안구 부분의 Optimold mask를 제거하였을 때 모의치료 시 $12.9cGy{\pm}2.2$, 치료 시 $17.6cGy{\pm}1.5$로 측정 되었다. 결 론 : 안구 부분의 Optimold mask를 제거하였을 경우 제거하지 않았을 경우에 비하여 모의치료 시 약 3 cGy의 선량이 증가하였고 치료 시 약 7 cGy의 선량이 감소하였다. 전 치료과정 중 수정체의 흡수선량이 약 27%감소되어 방사선감수성이 높은 수정체에 흡수되는 선량이 줄어 백내장을 일으킬 확률과 부작용을 감소시킬 수 있을 것으로 사료된다.

In this study, we have estimated lineaments in the Euiseong area, Kyungbuk Province, from Landsat TM by applying the algorithm developed by Kim and Won et al. which can effectively reduce the look direction bias associated with the Sun's azimuth angle. Fratures over the study area were also mapped in the field at 57 selected sites to compare them with the results from the satellite image. The trends of lineaments estimated from the Landsat TM images are characterized as $N50^{\circ}$~70W, NS~$N10^{\circ}$W, and $N10^{\circ}$~$60^{\circ}$E trends. The spatial distribution of lineaments is also studied using a circular grid, and the results show that the area can be divided into two domains : domain A in which NS~$N20^{\circ}$E direction is dominant, and domain B in which west-north-west direction is prominent. The trends of lineaments can also be classified into seven groups. Among them, only C, D and G trends are found to be dominant based upon Donnelly's nearest neighbor analysis and correlations of lineament desities. In the color composite image produced by overlaying the lineament density map of these C-, D-, and G-trends, G-trend is shown to be developed in the whole study area while the eastern part of the area is dominated by D-trend. C-trend develops extensively over the whole are except the southeastern part. The orientation of fractures measured at 35 points in the field shows major trends of NS~$N30^{\circ}$E, $N50^{\circ}$~$80^{\circ}$W, and N80$^{\circ}$E~EW, which agree relatively well with the lineaments estimated form the satellite image. The rose diagram analysis fo field data shows that WNW-ESE trending discontinuities are developed in the whole area while discontinuities of NS~$N20^{\circ}$E are develped only in the estern part, which also coincide with the result from the satellite image. The combined results of lineaments from the satellite image and fracture orientation of field data at 22 points including 18 minor faults in Sindong Group imply that the WNW-ESE trend is so prominent that Gumchun and Gaum faults are possibly extended up to the lower Sindong Group in the study area.
