  • Korean verb 'Casi-', which is treated as negative element in dictionaries, is actually a placeholder shows indefinite use, and '-ko casiko' construction is understood as a member of a class of 'Ending repetition construction'. However, unlike among others, '-ko casiko' construction is now undergoing developement of its negative polarity. Because of its indefiniteness, '-ko casiko' construction change its meaning into a universal negative when it is used in negative sentences.

  • This paper introduces a postprocessing method, an iteration method for melody, and an average neural network method for learning a large number of songs in order to improve musically insufficient parts in automatic composition using existing artificial neural network. The melody of songs composed by artificial neural networks is produced according to the melodies of trained songs, so it can not be a specific tonality and it is difficult to have a repetitive composition. In order to solve these problems, we propose a postprocessing method that converts the melody composed by artificial neural networks into a melody having a specific tonality according to music theory and an iteration method for melody by iteratively composing measure divisions of artificial neural networks. In addition, the existing training method of many songs has some disadvantages. To solve this problem, we adopt an average neural network that is made by averaging the weights of artificial neural networks trained each song. From some experiments, it was confirmed that the proposed method solves the existing problems.

  • They are used as a symbol representing some meaning of an object. Geometric patterns in the formative arts have been recasted by artists and used to express modern images. Simple shapes of geometric patterns create beauty with their outward appearance and decorated patterns. The simpleness of decorated patterns go with restrained, rational, and modern concepts. The patterns decorated with geometric patterns use geometric figures such as octagon, triangle, quadrangle, etc. and they give satisfaction to modern people. They are also regular and simple, so they can create impactive visual effects and three-dimensional space can be created with these dynamic patterns. Therefore, attractiveness of shape which gives enjoyment is also found in tableware design using geometric patterns. Using geometric patterns in tableware design is not based on a chance factor, so it is possible to objectify and reproduce the patterns. These repetitive designs can influence a lot of designers working on tableware and help improve the tableware designs. It is also considered that those designs are able to create new opportunities to produce a high value product in the ceramics industry.

  • Cracked component analysis is needed for structural integrity analysis under seismic loading. Under large amplitude cyclic loading conditions, the change in material properties can be complex, depending on the magnitude of plastic strain. Therefore the cracked component analysis under cyclic loading should consider appropriate cyclic hardening model. This study introduces a procedure for determining an appropriate cyclic hardening model for cracked component analysis. The test material was nuclear-grade TP316 stainless steel. The material cyclic hardening was simulated using the Chaboche combined hardening model. The kinematic hardening model was determined from standard tensile test to cover the high and wide strain range. The isotropic hardening model was determined by simulating C(T) test under cyclic loading using ABAQUS debonding analysis. The suitability of the material hardening model was verified by comparing load-displacement curves of cyclic C(T) tests under different load ratios.

  • This study examined figurative characters of rice terraces, and is intended to seek figurative possibility of a natural scene by selecting Gyeongnam Area Namhae Gacheon rice terraces, Sancheong Imcheon rice terraces and Hamyang Macheon rice terraces through an analysis of the target land. As a theoretical background, studies of a natural scene and figuration-related literature were looked into, and for figuring a natural scene on the basis of the results, the character of the topography of rice terraces was divided into 9 items as follows by generalizing the inspiration obtained from the natural scenic character and spatial character of rice terraces represented from the topography: (1) Inclination showing the degree of the slope of rice terraces, (2) The bending showed by unevenness of the edge line of rice terraces, (3) The degree of parallelism of the up-and-down edge line, (4) The size of the width of the section of each rice terrace, (5) The area of the total rice terraces, (6) Step gap that indicates the difference of high and low of the up-and-down small rice terraces, (7) Figuration as an image represented by the external form of the total rice terraces, (8) Naturalness and artificiality kept by the total scene, (9) Softness of cornerstones or soil that forms small rice terraces, an atmosphere produced by the total scenes, etc. The results of analysis made through GIS, with rice terraces of Gyeongnam Namhae, Sancheong and Hamyang Area as the target land, are as follows. First, the steeper the inclination is, the higher the step difference of cornerstones becomes, and the steeper the inclination, the narrower the area and width become, so that it could be known that, in rice terraces, inclination is proportional to step difference and the area is inversely proportional to the width. Second, it is considered that line showed in rice terraces, area elements and reiteration, repeated changes, and changes in the scene affected by the surrounding environment including those according to season can be converted into a variety of images according to an individual disposition. Third, it was decided that it is possible to figure repetitive composition and directivity, motility, order and change, etc. into a common type drawn from each target land. This paper, as a study of basic materials for expressing figuration in an environment field, investigated and analyzed the surrounding environment of the target land, and is significant in that it attempted the possibility of being able to generalize the environmental beauty of the target land as one figurative element. More precise studies are expected to be made later.

  • Extraction and selection of the informative features play a central role in pattern recognition. This paper describes a modified back-propagation algorithm that performs selection of the informative features and trains a neural network simultaneously. The algorithm is mainly composed of three repetitive steps : training, connection pruning, and input unit elimination. Afer initial training, the connections that have small magnitude are first pruned. Any unit that has a small number of connections to the hidden units is deleted,which is equivalent to excluding the feature corresponding to that unit.If the error increases,the network is retraned,again followed by connection pruning and input unit elimination.As a result,the algorithm selects the most im-portant features in the measurement space without a transformation to another space.Also,the selected features are the most-informative ones for the classification,because feature selection is tightly coupled with the classifi-cation performance.This algorithm helps avoid measurement of redundant or less informative features,which may be expensive.Furthermore,the final network does not include redundant parameters,i.e.,weights and biases,that may cause degradation of classification performance.In applications,the algorithm preserves the most informative features and significantly reduces the dimension of the feature vectors whiout performance degradation.

  • This study was carried out to investigate dietary effects of extracts of Skullcap (Scutellaria baicalensis) (SCE) grown in Korea on growth performance, immune and physiological responses in broiler chickens. Total of seven-hundred fifty 1-d-old Ross male broiler chicks were divided into five groups and fed control diets (antibiotics medicated or non-medicated commercial diets) or each experimental diet (non-medicated diets containing 0.1, 0.3 or 0.5% SCE) for 5 weeks. The body weight gain and feed conversion rate in the groups fed diets containing 0.1% or 0.3% SCE were significantly improved as compared with those of non-medicated control group (P<0.05). The levels of total cholesterol and HDL-cholesterol of blood were not influenced by feeding the SCE. The average antibody titers against NDV and IBV in the groups fed diets containing SCE were significantly increased compare to those of the control groups (P<0.05). The number of coli form bacteria was significantly reduced by feeding 0.3% or 0.5% SCE as compared to that of non-medication control (P<0.05). The results demonstrated that the SCE used in this study modulated humoral immunity and the profiles of cecal microflora and thus can be used as a potential alternative substance to replace antibiotics for feeding broiler chicks.

  • This study was conducted to compare and analyze meat quality of Korean native duck (KND) meat relative to stocking density. The stocking densities under investigation were 4, 5, 6, 7, 8 and 9 birds/㎡. The experiment comprised six treatments and four replications, wherein the breast meat (pH, meat color, and physicochemical properties) and leg meat (fatty acid contents) of 8-week-old KNDs (2.8±0.2 kg) were used. pH of breast meat decreased linearly and quadratically (P<0.05) as stocking density increased. Ash content also decreased linearly (P<0.05) as stocking density increased; however, moisture, fat, and protein contents did not differ significantly among treatments. Furthermore, meat color and cooking loss (CL) increased linearly (P<0.05) as stocking density increased whereas neither shear force (SF) nor water holding capacity (WHC) displayed a significant difference among treatments. Palmitic acid (C16:0) and stearic acid (C18:0) contents decreased quadratically (P<0.05) as stocking density increased whereas, conversely, linoleic acid (C18:1n9) and eicosenoic acid (C20:1n9) contents increased linearly (P<0.05) as stocking density increased. Additionally, γ-linoleic acid (C18:3n6) content increased linearly and quadratically (P<0.05) as stocking density increased, but a decrease (P<0.05) was observed in arachidonic acid (C20:4n6) content. Saturated fatty acid (SFA) and total unsaturated fatty acid (TUFA) contents did not show significant differences among treatments relative to stocking density. However, monounsaturated fatty acid (MUFA) content increased linearly (P<0.05) and polyunsaturated fatty acid (PUFA) content decreased linearly (P<0.05) as stocking density increased. These results can be utilized as basic data for research on the effect of stocking density on KNDs.
