Synonym means that the conceptual meaning of the word is the same or similar while other meanings or function of language difference may exist. That is two or more identified names correspond with one sense and have the words with minor difference. Words with synonym relation are a set of same meaning but conceptual area or emotional color, language function can be identified. Therefore, the core research of synonym is the difference analysis and in general difference analysis is progress in the three aspects of Meaning, Pragmatic, and Semantic. However, the difference analysis is the most important. In this paper, the set of meaning item of synonym word 'Attack' is 'zheng', 'fa', 'tao', 'qin', 'xi'. We compare the meaning of five verbs and analyze the difference and characteristics.

This paper presents a study on the construction condition and environmental effect of deep soil mixing. Construction condition means the difference in unconfined compressive strength with respect to the depth and location of samples. Environmental effect means alkalinity diffused from soil stabilizer. The experimental results indicate that the unconfined compressive strength vary with respect to the depth, and doesn't show consistency pattern. So, in field application we must decide a mixing ratio enough to satisfy the least unconfined compressive strength. The difference in unconfined compressive strength with respect to the location of samples is negligible. The generation of alkalinity from soil stabilizer is reduced by permeating in non-improved soil and it is expected that the diffusion of alkalinity has no environmental effect on soil and ground water.

In this paper, we propose a segmentation method of moving object using the spatio-temporal information in image sequences. Proposed method consists of motion detection step using difference image, region segmentation step using k-means algorithm, motion estimation step and segmenting step using intensity and motion information. Experimental results show that the method is capable of segmenting variously moving objects in image sequences.

We are defined a space as the activities of creating value in harmonic relations between human and environment. After Industrial Revolution, relations between human and space is changing because of speed and visualization's power in contemporary society. We we known information where is far by means of visualization. There is only difference of speed. Movement in space means the line of vision and circulation. But it is tried to think relations between human and space again in result to experience indirectly. This study aims at the analysis of expression of the modem Architecture space in Giedion' Space, Time, Architecture and aesthetic systems applied to it. On the basis of that , this study analyzed the difference of Bergson' consideration from Modern Architecture about movement.

To increase building change recognition accuracy, we present a deep learning-based building change detection using remote sensing images. In the proposed approach, by merging pixel-level and object-level information of multitemporal remote sensing images, we create the difference image (DI), and the frequency-domain significance technique is used to generate the DI saliency map. The fuzzy C-means clustering technique pre-classifies the coarse change detection map by defining the DI saliency map threshold. We then extract the neighborhood features of the unchanged pixels and the changed (buildings) from pixel-level and object-level feature images, which are then used as valid deep neural network (DNN) training samples. The trained DNNs are then utilized to identify changes in DI. The suggested strategy was evaluated and compared to current detection methods using two datasets. The results suggest that our proposed technique can detect more building change information and improve change detection accuracy.

In this paper, we propose a method of measuring Fine dust in images using K-means and Sobel-mask based edge detection techniques using CCTV. The proposed algorithm collects images using a CCTV camera and designates an image range through a region of interest. When clustering is completed by applying the K-means algorithm, outline is detected through Sobel-mask, edge strength is measured, and the concentration of fine dust is determined based on the measured data. The proposed method extracts the contour of the mountain range using the characteristics of Sobel-mask, which has an advantage in diagonal measurement, and shows the difference in detection according to the concentration of fine dust as an experimental result.

The purpose of this study is to analyze the effects of interaction based on contingent regulation between teacher and underachiever in elementary mathematics. For this purpose, research questions are established as follows; (1) Is there any difference between contingent regulation and natural regulation in mathematics achievement\ulcorner (2) Is there any difference between contingent regulation and natural regulation in affectionate perspective\ulcorner (3) Is there any difference between contingent regulation and natural regulation in adult regulation\ulcorner Two classes of fifth grade Children(10 children) were sampled from an elementary school in city of Daegu. One of them was assigned to the contingent regulation group and the other to natural regulation group. An experiment was conducted for 7 weeks. Two kinds of test instruments were used : pre-test and post-test. The pre-test scores guaranteed that both groups were homogeneous. Post-test was used to identify two effects(research questions (1) & (2)) and the post-test scores were analyzed by t-test. The results were as follows. (1) There was significant difference between contingent regulation and natural regulation in mathematics achievement. This means that experiment group was higher than control group and the interaction effect of contingent regulation was higher in post-test. The self-control indicated in experiment group. (2) There was slightly significant difference between contingent regulation and natural regulation in affectionate perspective. This means that experiment group turned to slightly positioner in post-test. (3) There was significant difference between contingent regulation and natural regulation in adult regulation. In other words, level of contingent regulation changed depending on underachievers' ability but level of natural regulation didn't change. Therefore, I suggest that contingent regulation based on Vygotsky theory would provide effective mathematics education for underachievers in elementary mathematics.

This study was performed to examine how intrinsic acceptance for happenstance(IAH) affects evaluation of the means to achieve additional goals when the additional goals are happened to be added to the original means-goal link. Specifically, participants were asked to evaluate the effectiveness of means(e.g., exercise and saving) to achieve additional goals which are either more or less relevant to the means. The result showed that participants with high IAH were more likely to think that the original means is effective to accomplish additional goals than those with low IAH. This pattern, however, was found only when the additional goals are relevant to the means. When the relevance of the additional goals to the means was low, there was no difference in evaluation of the effectiveness of the means to achieve additional goals between participants with high and low IAH. Future research and implications of this study for goal-systems theory and intrinsic acceptance for happenstance were discussed.

Human uses level difference and time difference to get space information. Therefore this paper shows that method to presume direction of sound source by time difference and to mark presumed position. The position means direction from geometrical center of sensors to the sound source. To get the time difference of microphones input level, we will be explained about arrangement of microphones which used for the sensor to take the sound signal. It is included distance among the 3 microphones and distance between microphones and sound source. Secondly, input signals are transmitted to CPU througth digital process. CPU is used to DSP(Digital Signal Processor) for manage the signal by real time. Finally, the position of sound source is perceived by an explained algorithm in this paper.
