Objective : The purpose of this study is to investigate the meaning of students’ experience participating in the flipped learning based instruction in sensory integration, and to understand the demand and introspection of participants. Methods : This study used a phenomenological approach of qualitative study. The participants were 10 students in 3rd year of the occupational therapy program in K Univeristy. Data information was collected by one-to-one interview and analyzed through phenomenological research method. Results : Through the interview, 20 units of meaning, 8 central meanings, and 3 themes were drew. The information collected were analyzed into three themes; Learning Experiences in Online and Offline Courses, Request and Introspection of Learners on Flipped Learning. The result showed that online courses brought learners convenience and satisfaction with repeatable learning in every time and space the learner want. However, the learners appealed issues of communication and concentration due to the absence of face-to-face instruction by their instructor. For the offline courses, students showed interest in various practical classwork of sensory integration and changes in their attitude to actively engage in the practical classes. Conclusion : Flipped learning based instruction was effective for the sensory integration classes which require practice in terms of time securement and immersion in practice. The learners requested for adopting flipped learning based instruction to other subjects in occupational therapy curriculum, and introspected that they needed to actively engage in classes through the experience of flipped learning-based classes of sensory integration. The results of this study can be used as a basic resource when flipped learning classes are planned in occupational therapy education. 목적 : 플립드 러닝기반 감각통합치료 수업을 받은 작업치료 대학생의 경험의 의미를 파악하고 수업 후 학습자의 요구와성찰을 알아보는 것이다. 연구방법 : 대학생의 플립드 러닝 기반 감각통합치료 수업 경험에 관한 질적 연구 중 현상학적 연구방법을 사용하였다. 본 연구의 대상자는 2017년 1학기 K대학교 작업치료학과 전공필수과목인 ‘감각통합치료 및 실습’을 수강한 3학년 학생중 10명이다. 자료 수집을 위해 일대일 면담방법을 이용하였고, 녹음한 면담내용을 전사하여 분석하였다. 결과 : 의미단위 20개, 중심의미 8개, 주제 3개가 도출되었다. 연구결과는 온라인 수업에서의 학습경험, 오프라인 수업에서의 학습경험, 플립드 러닝에 대한 학습자의 요구와 성찰의 주제로 분석하였다. 온라인 수업은 원하는 시간과 공간에서학습할 수 있다는 편리함과 반복학습의 만족감을 가져왔다. 하지만 교수와의 면대면 수업의 부재로 소통과 집중력의문제를 호소하였다. 오프라인 수업에서는 다양한 감각통합 실습수업에 흥미를 보였고, 적극적인 실습태도의 변화가있었다. 결론 : 실습이 요구되는 감각통합 수업에 플립드 러닝 기반 수업은 시간의 확보와 실습 몰입 면에서 효과가 있었다. 다른작업치료교과목도 플립드 러닝으로 수업하고 싶다는 요구가 있었으며, 플립드 러닝 수업을 통해 능동적인 학습 자세가필요하다는 성찰이 있었다. 본 연구의 결과는 작업치료 교육 분야에서 플립드 러닝 수업을 시도하는데 기초자료로 제공하고자 한다.

서영탁,공현호,이경무 대한근전도전기진단의학회 2016 대한근전도 전기진단의학회지 Vol.18 No.2

Objective: To investigate the relationship between the absent rates of superficial peroneal sensory nerve action potential (SNAP) and age increase in healthy adults without symptoms of peripheral neuropathy. Method: We recruited 120 healthy adults (240 low extremities) and divided into the age groups 20~29, 30~39, 40~49, 50~59, 60~69 and more than 70 years. All subjects underwent sensory nerve conduction study of superficial peroneal nerve. Diabetic history, exposed to neurotoxic agent, neurologic problem, trauma history on low extremity and pitting edema were excluded in this study. Results: All subjects of age groups 20~29, 30~39, 40~49 and 50~59 years were elicited, but 2 subjects (1.7%) in age group 60~69 years and 7 subjects (5.8%) in age group more than 70 years were not elicited. Increasing age and the no response rate of superficial peroneal nerve conduction study were correlated statically significant (p-value = 0.004). Using a receiver operator characteristic (ROC) curve, absent superficial peroneal SNAP could be observed more than 70.5 years with sensitivity of 77.8% and specificity of 89.2%. Conclusion: The ratio of absent superficial peroneal SNAP can be increase in elderly healthy adults. This study shows reference that superficial peroneal SNAP might be absent as age increase.

박근영,임선,김윤희,김영국 대한재활의학회 2009 Annals of Rehabilitation Medicine Vol.33 No.1

Objective: To analyze the bifurcating points of medial plantar proper digital (MPPD) nerve by using anatomical landmarks on plane coordinates and thus determine the ideal stimulation site for MPPD sensory nerve conduction studies. Method: We dissected 10 feet from five adult cadavers and identified the bifurcation points of the MPPD nerve. Two reference lines in relation to anatomical landmarks were defined. A vertical line connecting the mid-point of heel (H) and tip of great toe (G) was defined as the HG line. A transverse line connecting the navicular tuberosity (N) and tuberosity of 5th metatarsal bone (M) was defined as the NM line. The bifurcation points of the 10 MPPD nerves were expressed in X, Y coordinates in relation to these two axis. Results: The bifurcation points were located at approximately 40% (40.0±2.4; mean±SD) of the HG line from the mid-point of heel (H) and at approximately 37% (36.5±3.6) of the NM line from the navicular tuberosity (N). The majority of these points were found to be clustered close to the HG line. Conclusion: The data on the MPPD nerve bifurcation points may be useful to localize the appropriate stimulation site that could be used in MPPD nerve conduction studies.

[Purpose] The purpose of this study is to identify the general characteristics of single-subject studies in Korea related to sensory integration interventions for intellectual and autism spectrum disorders. It also aims to grasp the quality level of domestic studies using the quality indicators for evidence-based practice suggested by the Council for Exceptional Children(CEC). [Method] In this study, 11 single-subject studies of sensory integration interventions published in domestic journals from 2000 to 2021 were analyzed. The general characteristics of the study were identified by dividing it into publication year, participants, study design, independent, and dependent variables, and the quality of the study was analyzed based on 22 indicators in eight areas presented by the CEC. [Results] In domestic single-subject studies of sensory integration intervention for intellectual disabilities and autism spectrum disorders, there were more studies addressing intellectual disabilities than autism spectrum disorders, and it was found that various study designs, such as AB, ABA, and multiple-baseline designs, were used. The sensory integration intervention strategy used traditional sensory integration as the main strategy, and most studies used problem behavior and stereotyped behavior as dependent variables. As a result of the analysis according to the CEC quality indicators, there was no study that satisfied all indicators, and it was confirmed that the overall satisfaction rate was low. [Conclusion] Domestic single-subject studies related to sensory integration interventions for intellectual and autism spectrum disorders should be conducted more actively, and efforts to improve the quality of the research are needed. Based on this, sensory integration interventions should be applied to the fields of intellectual disability and autism spectrum disorder intervention. [목적] 본 연구는 지적장애 및 자폐성장애를 대상으로 수행된 감각통합중재 관련 국내 단일대상 연구의 일반적인 특징을 파악하고 CEC에서 제시한 증거기반실제(evidence-based practice)를 위한 질적 지표를 사용하여 국내 연구들의 질적 수준을 파악하는 것을 목적으로 한다. [방법] 2000년부터 2021년까지 국내 학술지에 게재된 감각통합중재 단일대상연구 11편을 분석하였다. 연구의 일반적인 특징은 출판연도, 연구 참여자, 연구 설계, 독립변인, 종속변인으로 나누어 파악하였으며 연구의 질적 수준은 CEC에서 제시한 총 8개 영역의 22개 지표를 바탕으로 분석하였다. [결과] 국내 지적장애 및 자폐성장애 대상 감각통합중재 단일대상 연구는 지적장애를 대상으로 한 연구가 자폐성장애를 대상으로 한 연구보다 많았으며 AB설계, ABA설계, 중다기초선설계 등 다양한 연구 설계를 사용한 것으로 나타났다. 감각통합중재 전략은 전통적 감각통합중재를 주된 전략으로 사용하고 있었으며 문제행동, 상동행동 등을 종속변인으로 하는 연구가 가장 많았다. CEC 질적지표에 따른 분석결과 모든 지표를 충족하는 연구는 없었으며 전반적으로 낮은 충족률을 확인할 수 있었다. [결론] 지적장애 및 자폐성장애를 대상으로 수행된 감각통합중재 관련 국내 단일대상 연구는 보다 더 활발하게 수행되어야 하며 연구의 질적 수준을 향상시키기 위한 노력이 필요하다. 이를 바탕으로 한 감각통합중재가 지적장애 및 자폐성장애 중재 현장에 적용되어야 한다.

Kim, Mi-Jung,Yoo, Cheol-In,Choi, Hyun-Ju 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.2

The present study was performed to assess peripheral neural involvement by exposure to hand-arm vibration. Segmental sensory nerve conduction in the median and ulnar nerves were measured in shipyard workers exposed to vibration. The subjects were 47 male adults exposed to hand-arm vibration and 7 healthy male controls. The subjects underwent an extensive bilateral neurophysiological examination. Sensory compound nerve action potential (SNAP) of the median and ulnar nerves in palm-finger and wrist-palm segments were measured by antidromic method. And SNAP of the median and ulnar nerves in wrist-proximal finger and wrist-distal finger segments were measured by orthodromic method. Result of sensory nerve conduction study was abnormal in 31 patients (66%) and normal in 16 patients (34%) of subjects. The pathological pattern in the hand-arm vibration exposed group was 13 patients (28%) of carpal tunnel syndrome, 18 patients (38%) of distal sensory neuropathy, 7 patients (15%) of multifocal and 1 patient (2%) of Guyon syndrome. The present study indicates that vibration-induced nerve impairments exist both in the finger-palm and palm-wrist segment of median and ulnar sensory nerves. The results suggest that segmental sensory nerve conduction study would be useful as objective indication of peripheral nerve impairment induced by the hand-arm vibration.

통상적 신경전도검사에서 이상이 없는 당뇨병성 감각 다발신경병증에서 발바닥신경전도검사

박경석,김범준,김진수,홍윤호,성정준,박성호,이광우 대한신경과학회 2009 대한신경과학회지 Vol.27 No.2

Background: The results of a routine nerve conduction study (NCS) are sometimes normal in diabetic patients with clinical manifestations of sensory polyneuropathy, especially in the early stage. We report on the value of a plantar NCS in diabetic sensory polyneuropathy with normal results from a routine NCS. Methods: Mixed nerve conduction data in the medial and lateral plantar nerves of both feet were obtained orthodromically in 47 normal subjects and 30 patients with diabetic sensory polyneuropathies with normal results from a routine NCS. The latency and amplitude of compound nerve action potentials (CNAPs) of plantar nerves were normal in the normal subjects. The results of a plantar NCS in the patient group were compared with these normal values. Results: Nerve conduction abnormalities were found in 14 patients (46.7%). The rates of abnormal findings were 33.3% (20 of 60 nerves) and 31.7% (19 of 60 nerves) in the medial and lateral plantar nerves, respectively. A definite polyneuropathy pattern was found in 10 patients (33.3%). The CNAP amplitude was low or absent in 12 patients (85.7%) with abnormal nerve conduction, and 8 patients (57.1%) showed a prolonged CNAP latency. Conclusions: A plantar NCS is useful for detecting nerve conduction abnormalities in diabetic sensory polyneuropathy when normal results are obtained from a routine NCS. The diagnostic sensitivity of a routine NCS can be significantly increased by adding a plantar NCS when evaluating patients with sensory polyneuropathies, especially in the early stage.

Objective Previous studies have shown the influence of visual and auditory sensory impairment on dementia incidence. In this study, we tested the hypothesis that the incidence of dementia will increase with visual and auditory impairments than with visual or auditory impairment.Methods Data from the Korea National Health Insurance Service database were used, including disease and medication codes from 2009 to 2018, and the 2011 national health check-up results. Participants were grouped based on their sensory abilities: normal, visual impairment, auditory impairment, and both visual and auditory impairments (dual sensory impairment). To compare the incidence of dementia, hazard ratios were calculated for each group, with reference to the normal sensory (NS) group. Sensitivity analyses were performed comparing dementia incidence from 2014 to 2018, excluding the onset of the disease in 2012 and 2013.Results We identified 8,289 cases of dementia during the seven-year follow-up. In the multiple Cox regression analysis, adjusted for sex, social economic status, age, comorbidities, smoking, alcohol consumption, and activity level, the auditory impairment (hazard ratio= 1.1908) and visual impairment (hazard ratio=1.3553) groups showed a significantly higher dementia incidence than the NS group. Dual sensory impairment (hazard ratio=1.5267) showed the highest incidence. The sensitivity analysis yielded similar results.Conclusion Visual and auditory impairments are associated with an increased risk of dementia, particularly in individuals with dual sensory impairment. Hence, visual and auditory impairments might have increased the risk of dementia through independent pathological processes. Therefore, preventing and correcting sensory impairment is necessary to reduce the risk of dementia.

A Cross-cultural Comparison of the Sensory Characteristics of Perilla Oil by American, Chinese, and Korean Panels

양정은,최은옥,정라나 한국식품과학회 2012 Food Science and Biotechnology Vol.21 No.2

This study was conducted to characterize and compare via sensory descriptive analysis the sensory properties of perilla oil products that are processed in different ways (roasted vs. non-roasted) and to perform a cross-cultural comparison of the sensory descriptions of this product set among 3 sensory panels (Korean, Chinese,and American). The Korean, Chinese, and American panelists generated 18, 12, and 16 sensory attributes,respectively, to describe the odor of the products. The Korean panel generated more attributes than the Chinese and American panels. Panelists from the 3 different regions used descriptors that were related to their individual experiences or cultural backgrounds and the odor attributes of American panelists were included references to nonfood products. These results show that culture and familiarity affect the perception of sensory attributes and the description of this product set.
