This study was conducted to investigate the effect of dietary Panax ginseng Leaves, (PGL), Dioscorea japonica Hulls(DJH) and Oriental Medicine Refuse(OMR) on meat quality and physico-chemical properties in meat sample of Korean Native Chicken(KNC). KNC were randomly assigned to one of the 4 dietary treatment : 1) control(commercial feed), 2) PGL(commercial feed supplemented with 5% Panax ginseng leaves) 3) DJH(commercial feed with 5% Dioscorea japonica hulls) 4) OMR (commercial feed with 5% oriental medicine refuse). They were feed one of the experimental diets for 12 weeks and slaughtered. 160 KNC raised for 20 weeks. In the proximate composition, moisture, crude protein and crude ash was no significantly difference. But fat content were tended to high in control. The heating loss of control, PGL, DJH and OMR were 28.44%, 30.44%, 28.83% and 25.71% and control, PGL, and DJH were higher compared with that of OMR. The WHC(whiter holding capacity) was contrary to heating loss. The shear value and pH did not show any difference among the treatment groups. There were no significantly different in meat color(L*, a*,　b*) between control and treatment groups (L*=63.20∼70.67, a*=2.20∼4.15, b*=2.70∼6.01). In sensory evaluation, juiciness, tenderness and flavor were not detected to panelist. Among fatty acid, oleic acid of DJH and OMR were higher than that of control and PGL(p<0.05). Also, saturated fatty acid/unsaturated fatty acid of control, PGL, DJH and OMR were 1.58, 1.58, 1.64 and 1.67, respectively. DJH and OMR groups was higher than control and PGL groups(p<0.05). Total amino acid contents was control>OMR>DJH>PGL. Major amino acid of KNC was comprised to glutamic acid, lysine, aspartic acid, leucine and arginine.

This study was conducted to investigate the influence of dietary Panax Ginseng Refuse(PGR), Dioscorea Japonica Refuse(DJR) and Oriental Medicine Refuse(OMR) on performance(feed intake, body weight gain, feed conversion, mortality) of Korean Native Chicken(KNC). KNC were randomly assigned to one of the 4 dietary treatment : 1) control(commercial feed), 2) PGR(commercial feed supplemented with 5% panax ginseng leaves) 3) DJR(commercial feed with 5% dioscorea japonica hulls and 4) OMR (commercial feed with 5% oriental medicine refuse). 160 KNC were fed one of the above experimental diet for 12 weeks and slaughtered at 20 weeks of age. Daily DM intake of control, PGR, DJR and OMR diet were 125.79g, 122.26g, 122.30g and 123.72g, respectively, with no significantly difference(p$>$0.05). The DM utilizability of control and DJR(62.89% and 61.20%) diets were higher(p$<$0.05) than those of PGR and OMR(55.44% and 59.76%)(p$<$0.05). 16 weeks weight of bird fed control, PGR, DJR and OMR diets were 1,436.6g, 1,427.2g, 1,546g and 1,422.0g respectively with DJR being the highest than other treatments(p$<$0.05). Total feed intake of control, PGR, DJR and OMR diets were 6,087g, 5,947g, 5,816g and 5,852g, respectively where control was higher than other treatments. The feed conversion of PGR, DJR and OMR were higher than the control. Chicken housed mortality of control, PGR, DJR and OMR were respectively 24, 15, 13 and 20 birds with rather lower mortality in the supplented groups(p$<$0.05). The body weight, carcass weight and carcass yield were not different among the treatments. But abdominal fat of chicken in control and OMR groups were higher than that of DJR and PGR groups.

Omnidirectional mobile robots are capable of arbitrary motion in an arbitrary direction without changing the direction of wheels, because they can perform 3 degree-of-freedom (DOF) motion on a 2-dimensional plane. In this research, a new class of an omnidirectional mobile robot is proposed. Since it has synchronously steerable omnidirectional wheels, it is called an omnidirectional mobile robot with steerable omnidirectional wheels (OMR-SOW). It has 3 DOFs in motion and one DOF in steering. One steering DOF can function as a continuously variable transmission (CVT). CVT of the OMR-SOW increases the range of velocity ratio from the wheel velocities to robot velocity, which may improve...

To understand the function of edges in perception of moving objects, we defined four questions to answer. Is the focus point in visual motion detection of a moving object: (1) the body or the edge of the object, (2) the leading edge or trailing edge of the object, (3) different in scotopic, mesopic and photopic luminance levels, or (4) different for colored objects? We measured the Optomotor Response (OMR) and Edge Triggering Response (ETR) of goldfish. We used a square and sine wave patterns with black and red stripes and a square wave pattern with black and grey stripes to generate OMR's and ETR's in the goldfish. When we used black and red stripes, the black leading edges stimulated an ETR under scotopic conditions, red leading edges stimulated an ETR under photopic conditions, and both black and red leading edges stimulated an ETR under mesopic luminance levels. For black and gray stripes, only black leading edges stimulated an ETR in all three light illumination levels. We observed less OMR and ETR results using the sine wave pattern compared to using the square wave pattern. From these results, we deduced that the goldfish tend to prefer tracking the leading edge of the pattern. The goldfish can also detect the color of the moving pattern under photopic luminance conditions. We decided that ETR is an intriguing factor in OMR, and is suitable as a method of behavioral measurement in visual system research.

With the development of computer music notation programs, when drawing sheet music, it is often drawn using a computer. However, there are still many use of hand-written notations for educational purposes or to quickly draw sheet music such as listening and dictating. In previous studies, OMR focused on recognizing the printed music sheet made by music notation program. the result of handwritten OMR with camera is poor because different people have different writing methods, and lens distortion. In this study, as a pre-processing process for recognizing handwritten music sheet, we propose a method for recognizing a staff using linear regression and a method for recognizing a bar using CNN. F₁ scores of staff recognition and barline detection are 99.09% and 95.48%, respectively. This methodologies are expected to contribute to improving the accuracy of handwriting.

The purpose of this study is to develop a framework for analyzing the solution spaces of open-ended task and to explore their usefulness and applicability based on the analysis of solution spaces constructed by students. Based on literature reviews and previous studies, researchers developed a framework for analyzing solution spaces (OMR-framework) organized into subspaces of outcome spaces, method spaces, representation spaces which could be used in structurally analyzing students' solutions of open-ended tasks. In our research, we developed open-ended tasks which had various outcomes and methods that could be solved by using the concepts of factors and multiples and assigned the tasks to 181 elementary school fifth and sixth graders. As a result of analyzing the student's solution spaces by applying the OMR-framework, it was possible to systematically analyze the characteristics of students' understanding of the concept of factors and multiples and their approach to reversible and constructive thinking. In addition to formal mathematical representations, various informal representations constructed by students were also analyzed. It was revealed that each space(outcome, method, and representation) had a unique set of characteristics, but were closely interconnected to each other in the process. In conclusion, it can be said that method of analyzing solution spaces of open-ended tasks of this study are useful for systemizing and analyzing the solution spaces and are applicable to the analysis of the solutions of open-ended tasks.

This study was conducted to investigate the influence of dietary oriental medicine refuse(OMR) and mugwort powder on physico-chemical characteristics of Korean Native Pork(KNP). KNP were randomly assigned to one of the three dietary treatments : 1) control (commercial feed) 2) T1 (commercial fed supplemented with 10% OMR powder) 3) T2 (commercial feed with 10% mugwort powder). 15 heads(♂) were feed one of the experimental diets for 5 months and slaughtered. In the proximate composition, moisture content showed slightly high in the T1, however, fat content were tended to be high in the control. The heating loss, shear value, WHC (water holding capacity) were not significantly between control and the treatments group. The T1 showed the lowest pH among treatments (P<0.05). In sensory evaluation, juiciness and tenderness of T1 and T2 were higher compared with that of control. Hunter a* did not show any difference among the treatments group. But Hunter L*, b* in treatment group(T1, T2) were higher than that of the control. Oleic acid, linoleic acid and unsaturated fatty acid contents of T1 and T2 were higher than the control. The total amino acid of the control, T1 and T2 were 18.290, 18.177 and 18.942mg%, respectively.
