MPEG-V(ISO/IEC 23005) standardizes normative sensory effects metadata and sensory devices command for adapting the sensory effects between the virtual world and the real world. MPEG-V(Virtual) standardization has been carried out by 3DG(Dimensional Graphics) ad-hoc group inside MPEG Working Group(ISO IEC JTC1/SC29/WG11). For the scent effect, one of the sensory effects within MPEG-V, we proposed an olfactory interaction model including electronic nose and scent display to the ad-hoc group. Recently, we proposed types and elements related to the electronic nose as a sensor defined in MPEG-V standard for olfactory interaction. At the 114th MPEG meeting, the types and elements were consequently reflected on MPEG-V CD(Committee Draft) 4th edition. In this paper, we implement an electronic nose system applicable to MPEG-V standard by using MPEG-V schema, encoder, and decoder in order to assess their adequacy.

Biological sensory systems continuously monitor and analyze changes in real-world environments that are relevant to an animal's specific behavioral needs and goals. Understanding the sensory mechanisms and information processing principles that biological systems utilize for efficient sensory data acquisition may provide useful guidance for the design of smart-sensing systems in engineering applications. Weakly electric fish, which use self-generated electrical energy to actively sense their environment, provide an excellent model system for studying biological principles of sensory data acquisition. The electrosensory system enables these fish to hunt and navigate at night without the use of visual cues. To achieve reliable, real-time task performance, the electrosensory system implements a number of smart sensing strategies, including efficient stimulus encoding, multi-scale virtual sensor arrays, task-dependent filtering and online subtraction of sensory expectation.

The purpose of this study is to provide definition of proprioception, foundations and roles of neuroanatomy, and systemical review of proprioceptive activities in sensory integration intervention. Proprioception exists in muscle, ligaments, joints and skin and it plays important role in controling body movements and interacting with environment during child development. Proprioception interacting with tactile and vestibular systems contributes to the change of muscle tone, postural control, refinements of planning and praxis. Children who are deficit in proprioceptive processing would seek hypo-responsive proprioceptive input or avoid hyperactive one. Outcome of poor proprioceptive input would cause the problems of praxis and postural control. Because proprioception provides information about the position and movement of body and limb it is important for development of body scheme and motor planning. It also influences the arousal and emotional tone. Sensory integration intervention which provides rich proprioceptive activities will improve the level of arousal and enhance motor planning.

This paper touches the limitations of existing theories related to technology acceptance, which mainly focus on users' perceived ease of use and usefulness, and proposes the role for sensory capabilities and enjoyment in understanding smartphone use. Furthermore, we develop a model that explains smartphone usage and intention to use it for a task and analyzes 442 questionnaire survey responses of smartphone users. First, perceived usefulness, perceived sensory capability, and perceived enjoyment influenced smartphone usage. Second, we found that both perceived usefulness and smartphone use were significantly associated with users' intention to utilize the smartphone for their job-related tasks. Finally, both perceived sensory capability and enjoyment were found to be more powerful factors than ease of use in explaining smartphone use. From the study findings, implications and future research directions are also discussed.

Objective : The aim of this study was to provide mechanism information of a link between arousal and sensory modulation to increase understanding of neurophysiological study. Subject : Optimal arousal state of a child is an important issue in sensory integration therapy. Limbic system and reticular formation are related to sensory modulation by sensory input. Sensory inputs processes from reticular formation to cortex via ascending reticular activation system for moderate arousal. A lot of neurotransmitters such as cholinergic neurons and monoamin neurons help this processes. Mechanism of arousal was measured by functions of central nervous system (CNS) and autonomic nervous system (ANS) using objective tools such as an electroencephalogram (EEG) and electrodermal responses. Functions of CNS and ANS showed differences between normal children and children with disabilities. Optimal sensory input using sensory integration therapy for children with disabilities helps to act reticular formation, limbic system, and cortex and to maintain appropriate arousal. Conclusion : Such quantitative studies by using neurophysiological methods provide evidence for sensory integration therapy.

Various electrophysiological tests have provided a large body of valuable information on neuronal responses to a presented stimulus. The special and general somatic sensory pathways are main targets of evoked potentials. Two types of evoked potentials, exogenous and endogenous, are commonly used. Exogenous evoked potentials of general and special somatic sensory systems will be reviewed. One of general somatic sensory functional pathways, proprioception, can be evaluated by general somatosensory evoked potentials with electrical stimulation on nerves. The special somatosensory functional pathways, including vision, and audition, can be evaluated by visual evoked potentials and auditory evoked potentials. Also laser-evoked potentials are newly developed for pain pathway, including lateral spinothalamic pathway, and vestibular myogenic evoked potentials for sacculocollic pathways. The evoked potentials of sensory system have maximal clinical utility in evaluating functional deficits along the sensory pathways. They are used for evaluating comatose patients, hysterical patients, premature infants, patients with suspected demyelinating diseases or neoplasms, and research. We discuss the neurophysiologic tests of sensory systems in views of practical points. The organized evaluation of sensory electrophysiologic tests can be helpful in detecting and estimating the abnormalities in neurological diseases.

Web structure of spiders is a foraging strategy as well as an investment to get prey. In order to make a good foraging decision spiders should change its foraging strategy in the basis of sensory information provided by potential prey species. We conducted experiments to demonstrate whether a wasp spider, Argiope bruennichi modifies its web-building behavior after experiencing sensory information emitted by a cricket species, Teleogryllus emma. To know how the web structures would be modified, we quantified web characteristics after providing sensory information of the cricket and compared to the control group. Web construction decreased in the course of the experiment in both, control group(without stimulus) and experimental group(with stimuli). The results did not show remarkable differences between two groups. However, on the first day after providing sensory information of the cricket, the web-building behavior of A. bruennichi decreased only in 3.7% of the experimental group individuals against 11.8% of the control group individuals. The number of the stabilimentum constructions decreased overall in both groups. On the first day the decreasing proportion was doubled in the control group(14.7%), comparing to the experimental group(7.4%). The individuals did not lower its web height and did not extend its web area according to sensory information of the prey.

Purpose : This study aims to investigate occupational therapy students' perceptions of sensory integration therapy and the effect of an educational program on these perceptions and future preferences. Methods : The participants were 200 occupational therapy students in Busan and Gyeongsangnam-do. A primary survey was first conducted to shed light on students' perceptions of sensory integration therapy, followed by an education program on sensory integration provided through an online video. After this training on sensory integration therapy, an additional survey assessed the their preferred employment routes and intention to take educational courses on clinical sensory integration therapy in the future. A secondary survey was then conducted, using the same form as the primary survey, to identify changes in the students' perceptions of and preferences for sensory integration therapy. A frequency analysis using descriptive statistics was employed to identify the participants' general characteristics, employment-related preferences, and intention to take courses on sensory integration, and a paired samples t-test was used for a comparative analysis of the students' perceptions before and after the education program. Results : In terms of the students' perceptions of sensory integration therapy, the variables of efficiency, facilitation, and expertise showed statistically significant differences before and after the educational program, which resulted in a positive change in their overall perceptions of the therapy after the program. In relation to their preferred employment routes after the program, 100 students (50 %) answered the "field of adults," and 100 (50 %) students answered the "field of children." Conclusion : The findings of this study demonstrated that sensory integration education positively influences occupational therapy students' preferences for and perceptions of sensory integration therapy. Additional research is recommended to organize a more systematic education program and investigate employees in organizations related to children with disabilities.

The physiological and sensory properties of breads made from waxy black rice flour (WBRF) and wheat flour were investigated. The waxy black rice bread was manufactured with 10, 20, 30, or 40% waxy black rice flour(w/w). The bread volume decreased from 2,096.7 mL to 1,703.4 mL as the WBRF content increased from 0% to 40%. The lightness(L-values) decreased with increasing WBRF concentrations, and the redness value(a-values) increased. The yellowness(b-values) slightly decreased with increasing WBRF content. The textural characteristics of the bread c겨mb were influenced by additions of WBRF. The breads containing WBRF had decreases in hardness for the 10% and 20% WBRF groups, whereas increases in hardness were shown with the 40% addition of WBRF. The springiness decreased with increasing WBRF content. The gumminess and chewiness of the waxy black rice bread decreased at the 10% and 20% additions. In the sensory evaluation, sensory scores decreased with increasing WBRF content for the appearance, external color, crumb color and grain of the waxy black rice bread. Overall acceptability for the 10% and 20% WBRF additions did not differ significantly from the score of the control group.
