  • From the point of breeding view for our future, 20 Korean varieties of red pepper for the contents of capsaicinoids, free amino acids, free fatty acids and organic acids with powder product and eating qualities were chosen, and the sensory properties of their water and ethanol extract were compared in order to investigate the influence of the composition of test components on sensory acceptability of Korean red pepper. The composition of taste components in red pepper powder varied wildly depending on the varieties; total capsaicinoids content variety from 0.029 to $0.913\%$, free sugar 8.45 to $20.2\%$, and organic acid 4.58 to $19.54\%$. Capsaicinoid contents especially dihydrocapsaicin content, were highly correlated with pungent taste of the methanol extract of red pepper power, but did not show significant relationship to the overall sensory acceptability. However, the components analyzed here and eating and processing qualities include high variations and future breeding sources.

  • The concept of single-modal digital art originated in the 20th century and has evolved through three key stages. Over time, digital art has transformed into multi-modal interaction, representing a new era in art forms. Based on multi-modal theory, this paper aims to explore the characteristics of interactive digital art in innovative art forms and its impact on user experience. Through an analysis of practical application of multi-modal interactive digital art, this study summarises the impact of creative models of digital art on the physical and mental aspects of user experience. In creating audio-visual-based art, multi-modal digital art should seamlessly incorporate sensory elements and leverage computer image processing technology. Focusing on user perception, emotional expression, and cultural communication, it strives to establish an immersive environment with user experience at its core. Future research, particularly with emerging technologies like Artificial Intelligence(AR) and Virtual Reality(VR), should not merely prioritize technology but aim for meaningful interaction. Through multi-modal interaction, digital art is poised to continually innovate, offering new possibilities and expanding the realm of interactive digital art.

  • P300 is widely used as a neurophysiological indicator of cognitive processing, which is known as reflecting controlled processing. MMN (mismatch negativity), early response prior to P300, is known as reflecting an early stage of information processing and having involuntary attention and automatic awakening or sensory memory. This study for normal people shows that electric potential of P300 and MMN are in close correlation (r=-0.673, p<0.05). That is, it is observed that the higher negative value electric potential of MMN measured at cerebral forehead-center has, the higher value electric potential of P300 measured at cerebral center-vertex has. This fact implies that working memory for temporary storage and operation of stimuli, and involuntary attention which constitute automatic information processing, an early stage of information processing, play a crucial role in efficient information processing. On the other hand, considering that MMN of cerebral forehead-center and P300 of cerebral center-vertex are in close correlation, it is necessary to pursue further study of cerebral parts which generate P300 and MMN in information processing.

  • 3D printing technology enables the production of creative and personalized food products that meet consumer needs, such as an attractive visual appearance, fortification of specific nutrients, and modified textures. To popularize and diversify 3D-printed foods, an evaluation of the printing feasibility of various food pastes, including materials that cannot be printed natively, is necessary. Most animal resources, such as meat, milk, and eggs, are not inherently printable; therefore, the rheological properties governing printability should be improved through pre-/post-processing or adding appropriate additives. This review provides the latest progress in extrusion-based 3D printing of animal resource-based inks. In addition, this review discusses the effects of ink composition, printing conditions, and post-processing on the printing performance and characteristics of printed constructs. Further research is required to enhance the sensory quality and nutritional and textural properties of animal resource-based printed foods.

  • To develop the processing methods of grape and increase the use of poor fruits, we researched the health drink made with them after making grape juice and vinegar. The grape heated at $80^{\circ}C$ during 30min was followed by filtration. Grape vinegar was prepared by alcohol and acetic acid fermentation of grape. Optimum initial alcohol concentration for acetic acid fermentation was 6-8%. Acetic acid fermentation of grape vinegar manufactured in onggi took 9 days and was faster than any other type of utensil. As the result of analysis of grape vinegar fermented in the various ratio of 'Campbell Early' and 'Kyoho' grape, the redness and total anthocyanin content and the score of sensory evaluation were higher in vinegar made with 100% 'Campbell Early'. The drink manufactured by adding grape vinegar was developed and adding 10% of grape vinegar to volume of grape juice and water mixture(1:1) was best in sensory evaluation. In this mixture, sugar content was $14^{\circ}$Bx.

  • For the manufacture of soybean cheese, curds were made from soy milk using either lactic starter or CaCl$_2$and ripened for 3 weeks. When papain was added during ripening, the amout of soluble protein increased. The yields of 3 soybean cheese were 76~88%, indicating that considerable loss of soy protein did not occur during the processing. During the period of ripening the change of moisture content was about 1 n. Total acidity of 3 soy cheese increased, demonstrating the production of lactic acid through lactic fermentation. Texture determined by Instron showed that 3 soy cheese had their own characteristic texture profile curve and that the cheese without papain treatment received the highest textural parameters. 3 manufactured soy cheese received 3-4 (good-very good) sensory scores in appearance, flavor and texture. General acceptibility of 3 cheese were evaluated as desirable or very desirable.

  • Globally, civil infrastructures are deteriorating at an alarming rate caused by overuse, overloading, aging, damage or failure due to natural or man-made hazards. With such a vast network of deteriorating infrastructure, there is a growing interest in continuous monitoring technologies. In order to provide a true distributed sensor and control system for civil structures, we are developing a Structural Nervous System that mimics key attributes of a human nervous system. This nervous system is made up of building blocks that are designed based on mechanoreceptors as a fundamentally new approach for the development of a structural health monitoring and diagnostic system that utilizes the recently developed piezo-fibers capable of sensing and actuation. In particular, our research has been focused on producing a sensory nervous system for civil structures by using piezo-fibers as sensory receptors, nerve fibers, neuronal pools, and spinocervical tract to the nodal and central processing units. This paper presents up to date results of our research, including the design and analysis of the structural nervous system.

  • This study was conducted to determine feasibility of utilization of Angelica acutiloba. Especially, the quality characteristics of bread prepared with the addition of Angelica acutiloba powder were investigated. Sensory evaluation and spoilage test were conducted for preparation of functional breads which added with ground plant matters (leaves and stems) from Angelica acutiloba. The result showed that the functional breads had high score of overall liking as well as low spoilage rate when added with 0.5 to 1.0% ground plant matters of Angelica acutiloba. Consumer acceptability evaluation showed a significant preference when added 0.5 to 1.0% ground leaves and stems of Angelica acutiloba into breads. Functional breads which added powder of Angelica acutiloba inhibited the growth of fungi. The more addition of Angelica acutiloba powder, the higher the degrees of this inhibited. These results suggested that the shelf-lives of the breads were extended by the addition of Angelica acutiloba powder. Further studies were required for improvement of functionality and diversity of bread products using medicinal plant materials as an additive.
