  • In this paper, an approach to dynamic systems control is addressed based on exploiting the potential features of the new nonlinear neural oscillator. Neural oscillators have recently enabled robots to exhibit natural dynamics using their robustness and entrainment properties. To technically accomplish this objective, the neural oscillator should be connected to the robot joints under the sensory feedback. This also requires the neural oscillator to adapt to the non-periodic nature of arbitrary input patterns. However, even in the most widely-used Matsuoka oscillator, when an unknown quasi-periodic or non-periodic signal is applied, its output signal is not always closely entrained. Therefore, current neural oscillators may not be applied to the precise control of the dynamic systems response. We illustrate the enhanced entrainment properties of the new neural oscillator by numerical simulation and show the possibility for implementation to control a variety of dynamic systems. It is verified that the oscillator can produce rhythmic signals for generating actuator signals which can be naturally modified by incorporating sensory feedback to adapt to outer circumstances.

  • This study concerns designing effective fuzzy inference rules, which can be used to evaluate other experiment sets for sensory tests. The number of fuzzy inference rules might be determined by the fuzzy division of variables. For the more the number of fuzzy division does not mean the more effectiveness, the number of inference rules should be reduced to improve efficiency of inference engine of expert system. This study verified that its suggested method and inference rules are effective in comparison with the existing studies.

  • In this paper, we propose a fuzzy inference model for a navigation algorithm for a mobile robot that intelligently searches goal location in unknown dynamic environments. Our model uses sensor fusion based on situational commands using an ultrasonic sensor. Instead of using the "physical sensor fusion" method, which generates the trajectory of a robot based upon the environment model and sensory data, a "command fusion" method is used to govern the robot motions. The navigation strategy is based on a combination of fuzzy rules tuned for both goal-approach and obstacle-avoidance based on a hierarchical behavior-based control architecture. To identify the environments, a command fusion technique is introduced where the sensory data of the ultrasonic sensors and a vision sensor are fused into the identification process. The result of experiment has shown that highlights interesting aspects of the goal seeking, obstacle avoiding, decision making process that arise from navigation interaction.

  • Objectives : This study was conducted to investigate the effects of fixed-intensity and varied-intensity electroacupuncture in pain and sensory threshold concerning parameters visual analogue scale(VAS), brief pain inventory(BPI) and quantitative sensory testing(QST), among chronic tension headache patients. Methods : Thirty patients with chronic tension headache were randomly assigned to three groups and received different kinds of electroacupuncture at $ST_{36}$ and $ST_{37}$. Group A received fixed-intensity electroacupuncture(fixed-EA), group B received varied-intensity electroacupuncture (varied-EA), and group C received only acupuncture treatment without electrical stimulation as a control group. The intervention was given three times per week, and continued in two weeks. All the experiments were conducted blindly. Results : Fixed-EA group showed a significant decrease of VAS and BPI compared to the baseline measurement, while both varied-EA and control group did not. Of the parameters of QST, subtraction of heat pain threshold(HPT) and cold pain threshold(CPT) slightly increased in all groups, but this was not significant. Conclusions : These results suggest that fixed-EA reduce pain and improve quality of life in patients with chronic tension headache and that acupuncture may regulate patient's pain sensitivity through changing sensory threshold.

  • Developing a menu for foodservice operations utilizing a Yaksun meets with the desire of customers who have keen interest in health food. In addition, it is possible to expect the additional advantage of decreasing hygiene risk, which can be caused by large quantity cooking, by the efficacy of medicinal herbs used in Yaksun. Accordingly, this study provides with basic information for the development of a Yaksun menu for foodservice operations utilizing Gwackhyang by evaluating the sensory quality and microbiological quality of bean soup added of Gwackhyang. The standard plate counting significantly decreased as the addition quantity of Gwackhyang increased (p<0.001). All bean soups, which were kept at room temperature and refrigerator for 3 hours after cooking, met the safety standard 5.00 CFU/g. The number of coliforms also significantly decreased as the addition quantity of Gwackhyang increased. The bean soups in control group exceeded the safety standard of 2.00 CFU/g after 1 hour at room temperature and in refrigerator. On the other hand, all Gwackhyang bean soups met safety standard, only excluding G1 with 1% Gwackhyang kept at room temperature. Accordingly, it has been confirmed that the addition of Gwackhyang during bean soup production decreases the microorganism level of bean soup. Both standard plate counting and the number of coliforms significantly increased after 3 days in refrigerator; however, the increasing extent of Gwackhyang bean soups were less than the control group bean soups. The control group received scored highest in 3 sensory characteristics out of 5 sensory characteristics. However, G1 with 1% Gwackhyang also scored highest in 2 sensory characteristics, which were taste and overall preference. G2 also scored 4.45 in color and 4.15 in fragrance, which were lower than the control group but were above average.

  • The purpose of this study was to provide the basic information for bread with kinds of spice. The qualities of bread added with garlic, ginger, and cinnamon powder were investigated using sensory and mechanical evaluation. The result of sensory evaluation showed that the softness, color, brittleness, hardness, and chewiness of bread were increased as the amount of garlic, ginger and cinnamon powder increased. Lightness decreased by the addition of garlic, ginger and cinnamon powder, while redness and yellowness increased. Texture measurement showed that hardness, cohesiveness, springiness, gumminess and brittleness were the lowest in the breads with 1% garlic, ginger and cinnamon powder, and increased as the added amount of spice increased. A positive correlation was observed between the sensory and mechanical properties in general, while hardness and chewiness have negative correlation with sensory properties. Sensory properties of wheat flour odor, roasted taste, springiness and swelling were positively correlated with the acceptability. Breads with 1% garlic, ginger, and cinnamon powder showed a good overall preference.

  • The application of consomme prepared with different ratios of ground beef and ground chicken to improve taste preferences and the cost of foodstuffs was attempted by reviewing fundamental data and the effect on the sensory and physical characteristics of treatment These treatments were prepared with different ratios(9:1(A), 7:3(B), 5:5(C), 3:7(D), 1:9(E) w/w) of ground beef and ground chicken, respectively. Sensory properties were evaluated in the aspects of both acceptability and intensity. From the acceptability aspect, A treatment showed the highest scores in smell, B in mouthfeel and taste, A and B in color and overall acceptability, respectively. In terms of acceptability, B treatment was favored most for color, mouthfeel, taste and overall acceptability except smell. The more the ground chicken, the higher the intensity aspect E treatment showed higher values than A in all the intensity aspects. Moisture contents and crude proteins increased by increasing the mixed ratio of ground beef, whereas crude ash, solid matter and pH increased by increasing the mixed ratio of ground chicken. Tumidity values were the highest in E treatment, whereas the lowest in A. Tumidity values were increased significantly by increasing the mixed ratio of ground chicken. Viscosity increased by increasing the mixed ratio of ground chicken. The highest viscosity was shown in E treatment The colorimetric lightness values(L) decreased and redness(a), yellowness(b) and total color difference values(AE) increased significantly by increasing the mixed ratio of ground chicken. This experimental study showed that A and B treatment had the highest values in overall acceptability. The results of analysis in crude protein, solid matter, tumidity and viscosity were increased by increasing the mixed ratio of ground chicken. B treatment prepared with a ratio of 7:3 of ground beef and chicken had the most favorable sensory quality. These results suggested the basic information to improve acceptability and to save the costs of Consomme recipes for foodservice institutions.
