Conventional occupational therapy (OT) is conducted under the observation of an occupational therapist, and there are limitations in measuring and analyzing details such as degree of hand tremor and movement tendency, so this important information may be lost. It is therefore difficult to identify quantitative performance indicators, and the presence of observers during performance sometimes makes the subjects feel that they have to achieve good results. In this study, by using the Unity3D and artificial intelligence (AI) speaker, we propose a system that allows the subjects to steadily use it by themselves and helps the occupational therapist objectively evaluate through quantitative data. This system is based on the OT of the sensory integration approach. And the purpose of this system is to improve children's activities of daily living by providing various feedback to induce sensory integration, which allows them to develop the ability to effectively use their bodies. A dynamic OT cognitive assessment tool for children used in clinical practice was implemented in Unity3D to create an OT environment of virtual space. The Leap Motion Controller allows users to track and record hand motion data in real time. Occupational therapists can control the user's performance environment remotely by connecting Unity3D and AI speaker. The experiment with the conventional OT tool and the system we proposed was conducted. As a result, it was found that when the system was performed without an observer, users can perform spontaneously and several times feeling ease and active mind.

In this study, we evaluated the physicochemical and sensory quality of Glazed Spanish Mackerel in Teriyaki sauce containing added lemon juice and ginger juice using a Sous vide Cook-Chill method. The products were stored at below $3^{\circ}C$ and then its physicochemical and sensory quality was estimated after varous storage periods(0, 5, 10, 15 days). Measured extent of 40.91~52.04% in extent and reheating after of 42.35~54.40% when moisture content and did not significant by storage period in all sample are until save 15 days. The VBN was increased as the storage period increased. A similar trend was observed after reheating, and while lemon juice additions was significantly low on 15 days(p<0.01). Based on the results of the sensory evaluation, the Teriyaki sauces containing the added lemon juice additions were evaluated that had a better sensory quality is excellent in external appearance, flavor, taste, texture, and acceptability than the control group, and while were the evaluated excellently in overall flavor and taste in occasion of were found to be excellent after the addition of ginger juice.

The effects of baking with broccoli powder on the consumer perception and sensory characteristics were investigated using a model system of cookies incorporated with broccoli powder as a value-added food ingredient. Broccoli powder was incorporated into cookie dough at 5 levels (0%, 1%, 2%, 3%, and 4%, w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at $170^{\circ}C$ for 8 min in an oven. The baked cookies were cooled to room temperature for 1 hour and packed in airtight bags prior to all measurements. Control received the most favorable mean score, which was not significantly different from samples with 1% broccoli powder for color preference (p>0.05). Results of the consumer preference on taste showed a similar trend. Consumers did not find any significant differences on aftertaste and flavor among samples prepared by replacing wheat flour with up to 2% broccoli powder (p>0.05). Overall, incorporation of 1% broccoli powder in the formulation would result in the most favorable broccoli cookies for the consumers without sacrificing the sensory qualities, while still taking advantages of health benefits of broccoli. Correlation analysis indicated that broccoli powder concentration was significantly negatively correlated with the consumer preference for color, taste, aftertaste, flavor, overall acceptability and positively correlated with sensory color, taste, and flavor (p<0.05). Consumers' color, taste, aftertaste, and flavor were well correlated with the overall acceptability (p<0.05). Sensory intensity results are also presented.

감태 분말의 대체량을 0-8%로 달리하여 스펀지 케이크를 제조한 후 물리화학적 및 관능적 품질특성을 측정하고 각 특성사이의 상관관계를 살펴보았다. 감태 분말의 대체 비율이 증가함에 따라 반죽의 비중은 점차적으로 증가하는 경향을 나타내었고, 케이크의 비체적은 감태 분말 대체에 따라 감소하고 굽기 손실은 증가하였다. 부피지수는 감소하는 경향을 보여 감태 분말의 비율이 높아지면 케이크의 부피가 작아짐을 알 수 있다. 밝기는 나타내는 $L^*$값은 유의적으로 감소하였으며(p<0.05), 경도는 점차적으로 증가하였다. 관능검사 결과 감태 분말대체에 따라 대부분의 관능 특성이 뚜렷하게 구분되었다(p<0.05). 한편 상관분석 결과 감태 분말의 대체수준은 $a^*$값과 관능적 경도(firmness)를 제외하고 모든 품질특성과 유의적인 상관관계를 나타내었다(p<0.05, p<0.01 또는 p<0.001).

Primary hyperparathyroidism (PHP) is a disease in which excessive amounts of parathyroid hormone (PTH) are secreted and calcium levels in the blood increase. Hypercalcemia caused by PHP has a major influence on the peripheral nervous system and produces symptoms such as muscle cramps, paresthesia, and proximal muscle weakness. Here we report a rare case of sensory-dominant polyneuropathy caused by PHP, which improved after surgery.

Every movement, perception and thought we perform is associated with distinct neural activation patterns. Neurons in the brain communicate with each other by sending electrical impulses that produce currents. These currents give rise to electrical fields that can be measured outside the head. It shows some variation on the electroencephalographic signals. In recent devices, the EEG signals measured from head surface are a sum of all the momentary brain activation. With these EEG signals, it is difficult to distinguish the patterns correlated with a certain event from the signals. However, the system must discriminate some patterns with some events especially for any kind of device as a brain control interface system. In this experiment, the sensory-motor cortex of humans has been extensively studied. Activation related to several movements on both sides of the sensory-motor cortices in imaginary. The activation patterns during imagination of several movements resemble the activation patterns during preparation of movements. The result represents the system based on the optimal filters discriminated at least 60% of mental imageries.

It is known that structure of Human's brain information system is controlled by cerebral cortex mainly. Cerebral cortex is divided by sensory area, motor area and associated area largely. Sensory area takes part in information from environment and motor area is actuation by decision as associated area determined. It is possible to copy brain information system by input-output pattern. but there is difficulty in modeling of memorizing new information. Such action is performed by Limbic Lobe and Papez circuit which is controlled by intrinsic emotion. So we need of definition of emotion's role in decision. In this paper, we define roles of emotion in intrinsic decision using Dynamic Cognitive Maps(DCMs). The emotion is evaluated by outside information then intrinsic decision performed as how much emotion variated. The dynamic cognitive maps take part in emotion evaluating process.

Appropriate physical position and balance means giving the least stress and the most useful biomechanically to the body. As this fails, one would have functional recovery problem regardless of disability. There reported better effective on Dynamic training rather than Static training for a proper recovery of physical position, and additionally required Sensory Feedback. Those who have disability of balance, especially Central Nervous System lesion should he provided with variety of Sensory Feedback, and also Dynamic Balance training used by is quite effective.

The suck/swallow/breathe(SSB) synchrony, serving as the earlist primary motor mechanism, is the rhythmical, coordinated pattern of sucking, swallowing and breathing. The development of an intact SSB is an important precursor for further sensorimotor and cognitive development including speech and language development, state regulation, postural control, feeding, eye/hand coordination and social/emotional development. Arousal means a neurological mechanism for preparing one's body to orienting stimulus. Its levels are regulated with an interaction of the reticular formation, the limbic system, the hypothalamus and the autonomic nervous system. General strategies such as blowing, sucking, chewing, munching and licking to effectively modulate arousal state are related to SSB. The SSB synchrony is an important treatment principle for children with sensory integration disorder and problems with the modulation of arousal. The purpose of this article is to review concepts of SSB synchrony and the underlying relation between the modulation of arousal and SSB synchrony.

Background: The purpose of this study was to investigate effects of six-week biofeedback training for prevention of falling in elderly persons. Biofeedback training for using the TETRAX system. Methods: Thirty healthy elderly persons(men=17, women=13) who were 79 years of mean age participated in sensory regulation training. They were trained for thirty minutes a day, three times per week. We measured subjects sensory regulated function by TETRAX system, and analyzed mean difference of observed variables by paired t-test between the pre and post test. Results: The first experimental group were significantly difference between pre and post test. The second control group were not significantly between the pre and post test. The third there are significant between group. Conclusion: The results of this study reveal that biofeedback training exercise will improve sensory balance function, and further studies needs to identify which specific factors are related to fall in the elderly population, and it is expected this study may contribute in reducing fall and therapeutic exercise in falling.
