This study investigated the relationships between sensory processing patterns and pain catastrophizing levels in well older adults to provide basic information for rehabilitation intervention. The participants of this study were 216 older adults aged over 65. The Adolescent/Adults Sensory Profile(AASP) was used to measure sensory processing patterns and the Pain Catastrophizing Scale(PCS) was employed to evaluate psychological variables of the pain. Self perception of the pain was measured with the Numerical Rating Scale(NRS). Gender and age differences were analyzed with t-test and relationships among sensory processing patterns, pain catastrophizing and pain symptom levels were analyzed with Pearson product-moment coefficients of correlation. Women had higher 'sensory sensitivity' and 'sensory avoiding.' The group over 75 years old had higher 'sensory avoiding,' 'low registration' and 'sensory seeking.' Women had higher pain catastrophizing and pain symptom levels. Negative correlations between 'rumination' and 'low registration' and 'helplessness' and 'sensory seeking' were found. Positive correlations were found between pain catastrophizing and pain symptom levels when they were 'sensory sensitivity' and 'sensory avoiding.' The results infer that sensory processing patterns are associated with psychological variables of the pain and there are differences based on gender and age. Further studies are warranted to support the results.

The purpose of this study was to provide instructional suggestions by investigating the spatial sense and spatial reasoning ability of 6th grade students. The questionnaire consisted of 20 questions, 10 for spatial visualization and 10 for spatial orientation. The number of subjects for the survey was 145. The processes through which the students solved the problems were the basis for the assessment of their spatial reasoning. The result of the survey is as follows: First, students performed better in spatial visualization than in spatial orientation. With regard to spatial visualization, they were better in transformation than in rotation. With regard to spatial orientation, students performed better in orientation sense and structure cognitive ability than in situational sense. Second, the students that weren't excellent in spatial visualization tended to answer the familiar figures without using mental images. The students who lacked spatial orientation experienced difficulties finding figures observed from the sides. Third, students had high frequency rate on the cognition and use of transformation, the development and application of visualization methods and the use of analysis and synthesis. However they had a lower rate on a systematic approach and deductive reasoning. Further detailed investigation into how students use spatial reasoning, and apply it to actual teaching practice as a device for advancing their geometric thinking is necessary.

The aim of this study is to look into sub-factors of spatial sense that can be contained in spatial sense of solid figure of mathematics curriculum and offer suggestions to improve teaching spatial sense of solid figures in the future. In order to attain these purposes, this study examined the meaning and sub-factors of spatial sense and the relations between spatial sense of solid figure and sub-factors of spatial sense through a theoretical consideration regarding various studies on spatial sense. Based on such examination, this study compared and analyzed textbooks used in South Korea, Finland and the Netherlands with respect to contents of mathematics curriculum and textbooks in grades, sub-factors of spatial sense, and realistic contexts for spatial sense of solid figure. In the light of such theoretical consideration and analytical results, this study provided suggestions for improving teaching spatial sense of solid figures in elementary schools in Korea as follows: extending contents regarding spatial sense of solid figures in mathematics curriculum and considering continuity between grades in textbooks, emphasizing spatial orientation as well as spatial visualization, underlining not only construction with blocks but also mental activities in mental rotation and mental transformation, comparing strength and weakness of diverse plane representations of three dimensional objects, and utilizing various realistic situations and objects in space.

The study aims to extract the framework of sub-factors of spatial sense, to develop test instruments based on the framework to investigate the actual spatial sense ability of fourth to sixth graders in elementary school and to analyze the results. According to the framework of sub-factors of spatial sense of the study, spatial sense has two factors of spatial visualization and spatial orientation. Spatial visualization is divided into mental rotation, mental transformation and figure-ground perception while spatial orientation is categorized into direction sense, distance sense, and location sense. Based on the framework, the test instrument for spatial sense ability was developed and the test was conducted to 430 fourth to sixth students in five elementary schools in capital areas. The following conclusions were drawn from the results obtained in the study. Firstly, the higher school year gets, the more spatial sense grows. However, spatial visualization is developed much more than spatial orientation and their order is reversed with higher graders. Secondly, the most insufficient abilities among fourth to sixth elementary school students' spatial sense were mental transformation of spatial visualization and location sense of spatial orientation. Thirdly, the reasons of differences in sub-factors of spatial sense and graders seem to be from effects of students' learning experiences of spatial sense of mathematics curriculum and the complexities of test items.

The purpose of this study was to compare the difference between the adaptive and internalizing/externalizing maladaptive behaviors of the sensory processing problemtic group classified from non-disabled preschoolers and to confirms the effects of sensory processing sub-factors on adaptive and maladaptive behaviors. This study participated in 335, 3-6 years typical preschoolers, carried out Short sensory profile, Vineland-II adaptive behavior scales. The study result in the sensory processing showed a significant positive correlation with the adaptive behavior, and a significant negative correlations were found in the internalizing/externalizing maladaptive behaviors. In the t-test, the problemtic group had lower adaptive behavior scores than the typical group. This study confirmed that atypical sensory processing affected not only adaptive behavior, but also internalizing/externalizing maladaptive problems, that sensory processing difficulties were more related to emotional and behavioral issues.

Octopus variabilis의 흡반을 광학현미경과 주사전자현미경 그리고 투과전자현미경을 이용하여 그 미세구조를 관찰하였기에 이에 보고하는 바이다. 또한 내측상피 부위 돌기구 조물 속에서 관찰된 세포들은 핵을 둘러싼 세포들이 공포화 현상으로 인하여 해면처럼 보였다. 이 세포들은 감각과 수축에 관여하는 해면질성인 세포로 생각된다. 외측 상피조직에서는 2종의 분비성인 감각세포(A 및 B형세포)차 2종의 상피성인 감각세포(C 및 D형세포)가 관찰되었다. 분비성인 감각세포는 감각이외에 점액분비 기능을 소지하였으며, 상피성인 감각세포는 상피의 지지와 감각기능을 수행하는 것으로 생각되었다. 흠반을 구성하고 있는 근섬유는 중앙이 기린 도나스 형태로서 10-15개의 종선이 나타났다. 또한 부위에 따라서는 근섬유들은 서로 집결하여 원주형의 근육 기등을 형성하기도 했는데 이들은 신경섬유에 의하여 서로 연결 되고 통제되었다.

Nowadays, some movie theaters provide additional sensory information in 3D movies to enhance visually induced motion perception. However, no studies have investigated how motion perception increases. Thus, in this study, we examined the effect of visual coherent sensory information on visually induced motion perception and quantification of sensory information. A visual stimulus rotated sinusoidally and visual coherent sensory information were applied as vibrations to a subject's foot. We measured the sway of the subject's body by using a force plate and somatosensory bar rotation that represents the subject's perception of the horizon using an encoder. By using this data, we obtained the weight of the sensory information using a Kalman filter. As a result, it was found that subjects rotated the somatosensory bar more when visual coherent vibrations were applied. The weight of vision also increased when visual coherent vibrations were applied. Thus, we can conclude that visual coherent sensory information tends to enhance visually induced motion perception and weight of vision.
