  • 본 연구에서는 회전 자극기를 이용하여 성별에 따른 회전 평형감각 특성을 분석하였다. 피검자는 정상성인 남녀 각각 10명에 대해, 두부회전과 rotatory chair test(RCT)에 의한 회전자극 전과 후의 변화정도를 살펴보았고, COP, Flicker Test, 적외선 카메라를 이용한 체열 측정 등을 통해 전정자극 특성을 평가하였다. 그 결과 COP를 통한 신체동요도 측정 결과 회전자극 제시 후 두부회전의 경우 총 누적거리가 1.47배, RCT의 경우 1.78배까지 증가했고, 플리커 치는 여성(8.6%)이 남성(5%)보다 높게 나타났고, 여성이 남성보다 회전자극에 민감함을 알 수 있었다. 또한, 남녀 모두 회전 자극 후 눈 주위의 온도상승이 미소하게 일어남을 알 수 있었다.

  • 감각적인 불쾌감을 야기하는 악취물질의 종류는 다양하며, 매우 낮은 농도에서도 감각기관을 자극할 뿐 아니라 물질간 반응이 복잡한 특징을 갖고있어 화학성분분석법과 함께 감각적인 자극수준을 평가하는 관능측정법을 병행하여 악취현상을 종합적으로 평가하게 된다 특히 매립지 등의 환경기초시설이 운영됨에 따라 나타나는 악취현상을 객관적으로 평가하기 위해서는 대기확산모델의 운영이 필요하며, 이를 위한 악취배출량 자료의 구축이 필요하게 된다. (중략)

  • The purpose of this study was to identify whether cutaneous sensory (CS) changes induced by mechanical intervention(MI) increases the trigger point threshold and muscle tone of the same spinal segment to neck disc patients. Thirty persons with Neck disc patients were recruited in this experiment. The subjects consisted of 10 men and 20 women. The mechanical stimulus group induced CS changes for 5 minutes using the Graston instrument and the control group received no action. The CS changes were estimated by using the Von Frey Filament, PPT changes were measured by using the pressure threshold meter and msucle tone changes were measured by using Myotone pro. CS threshold increased significantly when MI was applied (p<0.05). On the same spinal segment, increases in the right infraspinatus PPT and muscle tone was observed (p<0.05) and decreases in the right trapezius PPT was observed(p<0.05). However, the PPT and muscle tone changes in other muscles were not significantly different. Furthermore, the control group CS, PPT and muscle tone were not significantly different. As a result, CS changes induced by MI make to change PPT and muscle tone on the same spinal segment. Therefore, application of MI to the same spinal segment may be of clinical significance as a new rehabilitation method for increasing pain threshold, muscle tone and pain control in neck disc patients.

  • This study aims to empirically examine the effect of feedback on attention recovery. The role of feedback has been proven to be positive in particular to extend the limitation of attention resource. We studied the impact of feedback on attention by varying its type and modality. An experimental system was developed to observe how accurately the participants performed the pattern-matching task with differential feedback provided on a real-time basis based on the ADHD diagnostic model. Six university students participated in this study with 6 different feedback conditions and controlled conditions. The participants experienced the feedbacks before experiment. They was asked two hundred tasks in four feedback conditions. The difference of feedback effect according to different modality is to find within a subject. The results indicated that the combined feedback of cognitive with perceptual stimulus led better performance than the combined of perceptual feedbacks.

  • In this work, a transcranial magnetic stimulation(TMS) experiment on animals is performed to stimulate the brain cortex of the mouse using modulated signals. The proposed TMS system is composed of the inverter, transformer, capacitor, variable inductor, and stimulation coil to generate 1.5 mT magnetic field in the brain cortex of the mouse. The stimulation signal is modulated to square wave where the carrier frequency is swept from 85 to 91 kHz to investigate the stimulation effect. The experimental result shows that when the carrier frequency of the stimulation signal is lower than 89 kHz, the reaction of the mouse does not change while the stimulation signal which has the carrier frequency higher than 89 kHz results in decreasing the threshold of the stimulus for the pressure.

  • The purpose of the research study is to confirm in effectiveness of somatosensory stimulation and to propose ideal training strategy for functional recovery of stroke patients. Through the previous literatures, our study investigated to the advantages and disadvantages in electrical somatosensory stimulation for stroke patients. Also, our study suggested to applicable strategies and confirmed to growth direction about new somatosensory stimulation therapy for functional recovery in stroke patients. Result of research study, although many study demonstrated to the effectiveness about somatosensory stimulation therapy for stroke patients, many therapists have experienced many difficulties in somatosensory stimulation application for stroke patients in rehabilitation environments. Thus, few have the therapeutic tools for somatosensory or specific sensory input. However, apparently the previous literatures showed that effectiveness of somatosensory stimulation on functional recovery of patients with brain damage. In conclusion, we can be confirmed that an ideal somatosensory stimulation program is very effective in promoting recovery and the integrity of the somatosensory pathway of stroke patients. Furthermore, we anticipate that using the customized mechanical interface provides to positive effects in rehabilitation of patients with brain damage.

  • In this study, we assessed how participants represent various sensory stimuli experiences through behavioral ratings and physiological measurements. Utilizing intersubject correlation (ISC) analysis, we evaluated whether individuals' affective responses of dominance, arousal, and valence differed when stimuli of three modality conditions (auditory, visual, and haptic) were presented. ISC analyses were used to measure the similarities between one participant's responses and those of the others. To calculate the intersubject correlation, we divided the entire dataset into one subject and all other subject datasets and then correlated the two for all possible stimulus pair combinations. The results revealed that for dominance, ISCs of the visual modality condition were greater than the auditory modality condition, whereas, for arousal, the auditory condition was greater than the visual modality. Last, negative valence conditions had the greater consistency of the participants' reactions than positive conditions in each of the sensory modalities. When comparing modalities, greater ISCs were observed in haptic modality conditions than in visual and auditory modality conditions, regardless of the affective categories. We discussed three core affective representations of multiple modalities and proposed ISC analysis as a tool for examining differences in individuals' affective representations.

  • Objective : We investigated how sensory processing patterns contribute to temperament and character traits in undergraduate students. Methods : A total of 107 undergraduate students were recruited in September 2022 via convenient sampling method. They completed the Adolescent/Adult Sensory Profile and the Temperament and Character Inventory. Multiple regression models were applied to analyze the effect of sensory processing quadrants (low registration, sensation seeking, sensory sensitivity, sensation avoiding) on each temperament (novelty seeking, harm avoidance, reward dependence, persistence) and character (self-directedness, cooperativeness, self-transcendence) traits. Results : Sensation seeking significantly predicted high levels of novelty seeking, reward dependence, persistence, self-directedness, and self-transcendence but low harm avoidance. Low registration predicted high harm avoidance but low levels of reward dependence, persistence, and self-directedness. Reward dependence was predicted by high sensory sensitivity and low sensation avoiding. Conclusion : This study demonstrated that sensory processing patterns affected novelty seeking, harm avoidance, reward dependence, persistence, self-directedness, and self-transcendence in young adults.
