Objectives: This study aims to define the relationships between the sensory, cognitive and physical functions of young-old and old-old individuals. Methods: Participants were 10,451 elderly individuals aged 65 and above, raw data of a 2014 National Survey on Korean Older Persons was used. To investigate the relationships among the sensory, cognitive, and physical functions, a structural equation model was used. Results: The key analysis results are summarized as follows; 5% had poor vision function(young-old 3.5%, old-old 7.1%), 3.8% had poor auditory function(young-old 1.7%, old-old 6.7%), 33.0% had decline in cognitive function(young-old 30.9%, old-old 35.7%), 3.6% were disabled(young-old 1.6%, old-old 6.3%) and cognitive function influences physical function more greatly than does sensory function. Additionally, in the young-old groups, vision among sensory functions, attention among cognitive functions, and IADL among physical functions, turned out to be the most influential. However, in the old-old groups, auditory function among sensory functions, orientation among cognitive functions, and IADL among physical functions, turned out to be the most influential. Conclusions: This study implies that functions in the young-old and old-old individuals must be considered with all three functions-sensory, cognitive, and physical-together at the same time and that this comprehensive approach is necessary in national policy making.

The purposes of this study were to describe the level of vision and hearing impairments, depression and functional capacity, among Korean institutionalized elderly and to examine the relation-ship between sensory impairments, depression, and functional capacity in these people. The final pupose was to test the cognitive function path model using sensory competencies as predictors. A convenience sample of thirty nine male and 90 female subjects with a mean age of 80.5 were the subjects of this study. The subjects were tested for cognitive function, and vision and hearing impairments. Physical function and social function were measured by observation of designated task performance by the subjects. Their level of de-pression was measured using a Geriatric Depression Scale administered through an interview. Individual subjective ratings of hearing and vision were marked by the subjects, on a ladder scale. The results of the study showed that 48.8% of the subjects had a hearing impairment, 63.5% had a vision impairement, and 36.4% had both a vision and hearing impairement. The four sensory groups (no sensory impairement, hearing impairement, vision impairement, hearing and vision impairement) were tested for differences in depression, physical function, social behavior and cognitive function. The only significant difference that was found was in cognitive function, between the no sensory impairement group and the hearing and vision impairement group(F=3.25, P<.05), Subjective ratings of hearing showed a significant correlation with cognitive function(r=.34, p<.001) and with social behavior(r=.31, p<.001). There was no correlation between subjective vision ratings and cognitive function or social behavior. However there was a significant correlation between vision and hearing(r=.49, p<.001). There was also a significant negative correlation between age and vision(r=-.21, p<.01) and between age and hear-ing(r=-.34, p<.001). There was a significant correlation between depression and physical function (r=-.32, p<.001) but there was no correlation between depression and cognitive function or social behavior. Based on the literature review and the result, this study, a path model of sensory competence-> cognitive function- >social behavior was developed and tested : Perceived vision and perceived hearing were the exogenous variahles and cognitive function and social behavior were the endogeneous variables in the model. The path analysis result demonstrated an accept-able fit (GFI=.997, AGFI=.972, X$^2$=.72 (p=.396), RMSR=.019) between the data and the model. There was a significant direct effect($\beta$=.38) of perceived hearing on cognitive function. There was a significant direct effect ($\beta$=.32) of cognitive function on social behavior. The total effect of hearing on social behavior was $\beta$=.32 including the indirect effect ($\beta$=.12) . However perceived vsion had little effect ($\beta$=-.08) on cognitive function. The result of path analysis confirms that hearing levels influence cognitive function, and both hearing and cognitive function levels influence social behavior. However, vision has little effect on cognitive function or on social behavior. For the next study, a combined model of the pre viously developed environment - >depression- > physical and social function model, and the present cognitive function model, should be tested to further refine the functional capacity model. There also a need for longitudinal study of functional capacity and sencory competence in order to better understand how declining sensory competence influences functional capacity and how it effects in-creasing dependency and nursing needs in the elderly.

Background: Mild cognitive impairment (MCI) is also called as aging related memory damage. Decreased cognitive function due to aging is known to be associated with the frontal lobe. Alpha wave is generated in the dominance in the frontal lobe or a wide range of regions in the brain, it should be doubted that the brain function might be degraded. Objective: To determine the effect of sensory stimulation type on learning and brain activity pattern of elderly persons with MCI. Design: Randomized Controlled Trial (single blind) Methods: Twenty elderly persons aged more than 65 with MCI were randonmized to simultaneous visual/auditory stimulation group (SVASG) and or auditory stimulation group (ASG). Ten peoples were assigned to each group and lectroencephalogram test was performed to individuals. In the electroencephalogram test, electroencephalography of prior to sensory stimulation, and during sensory stimulation were measured to compare brain activity pattern according to the study groups and measurement period. Results: The relative alpha power due to a sensory stimulation type showed that the SVASG significantly decreased in the left frontal lobe and the left parietal lobe statistically compared to those of the ASG while sensory stimulation was given (p<.05). The relative beta power due to a sensory stimulation type showed that the SVASG significantly increased in the left and right frontal lobes, the left and right parietal lobes, and the left temporal lobe statistically compared to those of the ASG while sensory stimulation was given (p<.05). Conclusions: Electroencephalographic analysis showed that the type of sensory stimulation can affect the brain activity pattern. However, the effects were not studied that which brain activity pattern help to improved cognitive function of elderly persons with mild cognitive impairment.

The primary purpose of this study was to investigate the influence of Cognitive Factors (CF) on the Creative Abilities (CAs) in design. We set up a model of Cognitive Design Process (CDP), which consists of four domains: Concepts, Experience, Five Senses (FS), and Thinking Modes (TM). Here, experience is first perceived by the five senses, and then recognized by intelligence. We regard design as a transforming process from concept to experience. For this study, two major Sensory Modalities (Visual and Kinesthetic), four Thinking Modes (Brain Dominance Profile), and four Creative Abilities (Fluency, Flexibility, Originality, and Elaboration) were reviewed. We hypothesized that idea generation is influenced by different Sensory Modalities (Visual Sense vs. Kinesthetic Sense) and Thinking Modes, and that these have a close relationship with the attributes of CAs. Firstly, we have examined the cognitive thinking model in design. Then, we adapted the Test of Creative Abilities of Design Thinking (TCADT) for measuring CAs. We surveyed the CAs under CF in particular. Finally, we have investigated the influences of the different Sensory Modalities (Visual Sense vs. Kinesthetic Sense) on CAs. It was found that a close relationship between Brain Dominance and CAs, and Sensory Modalities (SM) have different influence on these creative abilities. As a result, a tool for the Test of CAs and a framework for creative idea generation with the effective CF will be presented. These provide the basis for a new approach to creative idea generation in Experience Design.

Purpose : In this study, we applied a computerized cognitive rehabilitation program (CoTras-C) for children with cerebral palsy. Research was conducted to investigate the impact of upper limb function, sensory function, and activities of daily living. Methods : The study period lasted 10 weeks from October 2019 to December 2019. The study subjects were 12 subjects according to the selection criteria, and a computerized cognitive rehabilitation program (CoTras-C) was conducted twice a week for 30 minutes before and after the application of basic occupational therapy. Results : As a result of the computerized cognitive rehabilitation program, scores of upper limb function (QUEST), sensory function (SSP-2), and daily life activity (WeeFIM) were significantly improved (p>.05). From the result of examining the motor area, improvement in fine-motor function and protective extension through touch pad or controller operation was found. It also showed improvement in activities of daily living including motor and activities of daily living including social cognition. In the sensory function evaluation, it was not significant in movement sensitivity. Significant differences were shown in the items excluding olfactory/taste sensitivity. Conclusion : The application of the computerized cognitive rehabilitation program (CoTras-C) showed significant results in upper limb function, sensory function, and daily life activities of children with brain lesions. Based on these results, future studies need to generalize the study by expanding the age or population of children with brain lesions, or by expanding the diversity of diseases and environments.

This study was to investigate the effects of the sensory-motor training program childhood body concept and to investigate the difference between the control group and experimental group. Subjects of the study were compared with children whose age varied from three to four years old, where I.Q was over 100. The major things of this study was as follows, First, sensory-motor training program was effective with regards to body concept improvement among the three-, four-year-old children. Second, both the experimental group trained by sensory-motor program and the control group trained by cognitive-perceptual training program were revealed a meaningful performance. But, sensory-motor program offering subcognitive sensory body experiences yielded higher mean gains in scores than a cognitive-perceptual program. Sensory-motor learning is more effective than verbal learning is promoting body concept reflected in the ability to draw human figures.

연구는 기존 연구들이 단일한 개념으로 인식하고 있던 혁신성향 개념을 인지적 혁신성향과 감각적 혁신성향으로 구분하고 두 유형의 혁신 성향의 정도에 따라 신제품에 대한 소비자의 지각된 위험의 민감성이 다름을 보였다. 이러한 지각된 위험의 유형과 수준의 차이는 각각의 혁신 성향이 소비자의 신제품 구매의도에 있어 서로 다른 영향력이 있음을 보여 줌으로써 혁신성향이 소비자의 신제품 구매의도에 미치는 경로가 이중경로임을 제시하였다. 217명을 대상으로 회귀분석과 공변량 구조 분석을 통하여 실증 분석을 수행한 결과 감각적 혁신성향 보다 인지적 혁신성향이 높을수록 사회적 위험보다 기능적 위험을 더 많이 지각하는 반면 감각적 혁신성향이 높을수록 기능적 위험보다는 사회적 위험을 더 지각하는 것으로 나타났다. 즉, 신제품 구매에 따른 기능적 위험 지각과 사회적 위험 지각이 소비자의 혁신성향의 유형에 따라 다르게 나타남을 제시하였다. 기존 연구에서는 소비자의 혁신성향 개념을 하나의 구성 개념으로 파악하여 신제품 구매의도에 대한 영향 관계를 파악하였으나 본 연구는 감각적 혁신성향과 인지적 혁신성향으로 소비자의 혁신성향을 구분하고 신제품 구매의도와의 관계를 파악하였으며 각각의 혁신성향이 신제품에 대해 인지하는 지각 위험의 경로를 달리함을 밝혔다.

Itch is one of the most distressing sensations that substantially impair quality of life. It is a cardinal symptom of many skin diseases and is also caused by a variety of systemic disorders. Unfortunately, currently available itch medications are ineffective in many chronic itch conditions, and they often cause undesirable side effects. To develop novel therapeutic strategies, it is essential to identify primary afferent neurons that selectively respond to itch mediators as well as the central nervous system components that process the sensation of itch and initiate behavioral responses. This review summarizes recent progress in the study of itch, focusing on itch-selective receptors, signaling molecules, neuronal pathways from the primary sensory neurons to the brain, and potential decoding mechanisms based on which itch is distinguished from pain.

The purposes of this study were to(a) develop theoretical modifications of the extended gate control theory of pain using Fishbein's model and（b) test the efficacy of these modifications. Attitude, social subjective norm, personal subjective norm, habit and state anxiety were operationalized to represent internal stimuli for the cognitive-evaluative and motivational-affective dimensions of the theory. Pain expression was operationalized as sensory and affective responses to pain, and pain endurance. Sixty-two female nurses from 20 to 50 years of age participated. A semantic differential scale measured attitude and motivations to comply; a Likerty-type scale measured personal and social norms and habit. Spielberger's STAI measured state anxiety, Pain was produced using a modified submaximum effort tourniquet technique. Pair expression was measured using ratio scales of sensory intensity and unpleasantness developed by Gracely and his associates. Pain endurance was measured by subtracting time of pain threshold from pain tolerance. The first hypothesis examining whether pain endurance would be more significantly related to the affective response than to the sensory response was net rejected. Four remaining hypotheses, testing the ability of the five variables to predict the sensory and affective responses were not rejected. However, the habit of pain expression and the attitude toward pain expression contributed to the prediction of both sensory and affective responses to pain. The interaction between the cognitive-evaluative and the sensory-discriminative dimensions and the interaction between the cognitive-evaluative and motivational-affective dimensions were partially supported by the data from these two variables. The interaction between the motivational-affective and the sensory-discriminative dimensions was also supported by the relationship of sensory to affective responses. The variables which did not significantly predict pain expression appeared to have potential for prediction. Revision and testing of the tools for better reliability, validity, and clinical usuability are needed. The study contributed to theory building. The identification of variables which pre-dict pain behavior must occur before effective nursing interventions can be developed.

본 연구는 한국 노인이 주관적으로 인식하는 감각장애와 인지기능 간의 관계 조사이다. 연구방법은 2017년 노인실태조사 자료를 활용하여 65세 이상 10,082명에 대한 주관적 감각장애에 대한 평가 자료와 MMSE-DS를 통한 인지기능 간 관계를 위계적 다중회귀분석과 로지스틱 회귀분석을 실시하였다. 연구결과 시력, 청력, 구강 기능에 대해 주관적 불편감을 보고할수록 인지기능 감소의 위험이 높게 나타났다. 또한 청력, 구강에 대한 불편감은 치매로 이어질 가능성이 높음을 발견하였다. 특히 다른 감각기능에 비해 청력 불편감이 치매의심 집단의 인지기능과 상관관계가 가장 높은 것으로 나타났다. 본 연구의 결과는 노인의 감각기능을 정부 차원에서 관리할 필요성이 있으며, 노인 스스로 감각기능의 신체적 변화를 지각하고 평가하기 위한 도구를 개발할 필요가 있음을 제안한다. 아울러 노인의 건강 증진을 위한 구체적인 방안을 위한 연구가 필요하다.
