This study investigates the waiting and resting behaviors of children within a restorative healthcare facility design. In particular, the aim is to compare children with and without disabilities and reveal similarities and differences in terms of their behavioral characteristics and uses of design facilities, related to positive distraction, for restoration in the hospital. Three major common spaces for outpatients in S children's hospital in Seoul were examined including the main lobby and two waiting and resting spaces in the pediatric and rehabilitation medicine departments, respectively. A total of 155 children under the age of 12-67 with physical disabilities and 88 without-were observed while they waited and rested at the three spaces before or after doctors' examination. Basic demographic information and waiting and resting behavioral characteristics were compared between the two groups. The results indicated that the disabled children were more restricted in terms of space, facilities used, and social behaviors. However, regardless of disabilities, the children showed more positive distractions related to cognitive and social behaviors in areas where restorative design elements such as an aquarium, garden, or visual images were available. Based on the results, design implications were discussed to strengthen positive distraction behaviors in children with and without disabilities and to foster the restorative quality of the spaces for waiting and resting in the children's hospital.

Objective: Dual-task interference is defined as decrements in performance observed when people attempt to perform two tasks concurrently, such as a verbal task and walking. The purpose of this study was to investigate the changes of gait ability according to the dual task interference in chronic stroke survivors. Design: Cross-sectional study. Methods: Ten chronic stroke survivors (9 male, 1 female; mean age, 55.30 years; mini mental state examination, 19.60; onset duration, 56.90 months) recruited from the local community participated in this study. Gait ability (velocity, paretic side step, and stride time and length) under the single- and dual-task conditions at a self-selected comfortable walking speed was measured using the motion analysis system. In the dual task conditions, subjects performed three types of cognitive tasks (controlled oral word association test, auditory clock test, and counting backwards) while walking on the track. Results: For velocity, step and stride length, there was a significant decrease in the dual-task walking condition compared to the single walking condition (p<0.05). In particular, higher reduction of walking ability was observed when applying the counting backward task. Conclusions: Our results revealed that the addition of cognitive tasks while walking may lead to decrements of gait ability in stroke survivors. In particular, the difficulty level was the highest for the calculating task. We believe that these results provide basic information for improvements in gait ability and may be useful in gait training to prevent falls after a stroke incident.

최근 정신지체아들을 위한 음악교육의 중요성이 크게 부각되고 있으나 그들의 인지적 정의적 결함으로 인해 종래의 일반적인 음악수업 방식만으로는 음악 인지를 발달시키는 학습을 기대하기 어렵다. 이에 본 연구에서는 MMCP (Manhattanville Music Curriculum Program)이론에 근거한 정신지체아의 음악인지능력 (음악 동일성, 음악 유목화, 음악 서열화)을 향상시키기 위한 컨텐츠를 설계하였다. MMCP 이론은 음악의 본질을 이해시키며 특징음악 (18~19C의 음악) 만을 취급하는 음악이 아닌 모든 민족의 음악문화를 이해하고 포함하는 보다 포괄적인 음악교육이다. 본 시스템으로 기대할 수 있는 효과로는 첫째, 정신지체장애인의 음악적 인지 발달 뿐 아니라 인지적, 신체적, 사회적, 정서적 발달을 고양시킬 수 있다. 둘째, 정신지체장애인을 위한 개별화 음악교육이 가능하다. 셋째, 능동적이고 상호작용적인 음악교육이 가능하다.

이 연구에서는 기존의 지능형 교수기계와 또래 튜터링의 단점을 보완하여 '가르치기를 통한 학습'을 위한 교수가능 에이전트(Teachable Agent, 이하 TA) 의 이론적 배경 및 설계방안을 제시하고자 한다. TA는 학습자가 컴퓨터 에이전트를 가르치는 과정을 통해 학습하는 시스템으로 교수 Module, 묻고 답하기 Module, 테스트 Module, 학습자료 Module 등의 4 가지 Module로 구성된다. 교수 Module에서는 개념도(concept map)의 구성을 통해 튜터 역할을 하는 학습자가 TA 의 심성모형 (mental model)을 수정하고 update하게 되며, 묻고 답하기 Module에서는 인터렉티브 창을 통해 튜터와 TA가 제한된 방식으로 학습내용에 관한 질문과 응답을 함으로써 개념도를 수정보완하게 된다. 테스트 Module에서는 튜터가 가르친 TA가 미리 정해놓은 학습목표에 도달하였는지를 평가하게 된다. 테스트 결과 TA가 일정 수준에 도달하지 못한 경우에는 개념도의 재수정 과정을 통해 계속적인 학습이 이루어지도록 한다. 학습자료 Module은 튜터가 참고할 자료를 제공해 주는 Module이다. 이러한 TA는 튜터의 역할을 담당하는 학습자에게 깊이 있는 인지적 처리와 능동적인 학습동기를 경험하도록 함으로써 실제 교육현장에서의 유용한 교수/학습도구로 활용될 수 있을 것으로 기대된다.

It is expected that the Fourth Industrial Revolution will have a great impact on the manufacturing industry, especially as it will cause big changes in industry, economy as well as socio-cultural. To cope with this situation, each country is promoting the policy of cultivating its manufacturing. This study derives the effect of the fourth industrial revolution on product lifecycle management for smart manufacturing through expert's cognitive analysis. The knowledge area of product lifecycle management is divided into Project Portfolio Management, Collaborative Product Design, Customer Needs Management, Direct Material Sourcing, Product Data Management, Digital Manufacturing & Engineering, R&D Foundation, New Product Development through academic research. The expert survey was conducted in five different perspectives: Importance, Insufficiency. Then, using the results of the survey and the academic research the implication about Product Lifecycle Management were derived. The significance of this study is that it derives the change areas and factors of the product life cycle management knowledge domain in preparation for the fourth industrial revolution according to the perspective of importance and insufficiency.

The purpose of this study was to show the occurrences of musculoskeletal disease in aging society and basic information on developments of a systematic prevention program and proposed management measures needed to prevent the disease. The Korea Occupational Safety & Health Agency has analyzed cases of industrial accidents that cause musculoskeletal disease, from 1998 to 2007. They found 30,439 people suffering from the disease during those ten years. This information is from the Ministry of Labor's industrial accident analysis and the industrial accident survey from the Korea Occupational Safety & Health Agency. The data was analyzed by age and industrial classification. In Korea, according to the studies on aging society, the occurrence of musculoskeletal disease in elderly employee's have increased, so prevention programs are needed. Psychological, mental and cognitive programs are needed, as well as other prevention programs to ensure health in old age. In this study, we were able to see the state of musculoskeletal disease in aging society and the countermeasures to prevent the disease, such as a universal design, guarantees, and recuperation services. Later, we found that studying the various elderly patients would be of great help to us.

'프로그래밍은 어렵다'라는 인식이 학습자들 가운데 퍼져있다. 실제로 대학교육에서 프로그래밍 수업의 중도 포기율이 다른 강좌들에 비해 높은 것을 볼 수 있다. 따라서 학습자들이 프로그래밍을 왜 어렵게 생각하는지 인지적인 측면의 분석을 통해 그에 대한 적절한 교수 전략이 필요하다. 최근에 뇌과학의 발달을 통해 뇌가 어떻게 학습하고 어떤 상황에서 가장 효과적으로 활동하는지 파악하여 적절한 학습 환경을 구축하기 위한 뇌친화적 학습에 대한 연구들이 진행되고 있다. 본 연구에서는 뇌친화적인 학습 원리를 기반으로 하여 프로그래밍 수업에 대한 교수 설계를 하였다.

Purpose This study was conducted to identify the multidimensional role of institutional mechanisms in the linear relationship of satisfaction, trust and repurchase intention, which are used as an important concept in the research of e-commerce. To this end, a research model was proposed by combining concepts which are the concept of perceived effectiveness of institutional mechanisms for overall e-commerce environment(e.g., PEEIM) and the concep of perceived effectiveness of institutional structures(e.g., PEIS) of a specific marketplace based on the social cognitive theory. Design/methodology/approach This study was conducted by dividing the data into two groups to identify institutional mechanisms and trust-building relationships according to the institutional contexts inherent in e-commerce. The institutional contexts were set up for the top two online companies and the bottom two online companies according to the results of the open market brand assessment from 2018 to 2019 in South Korea. Findings The result of this study found that PEIS had a direct impact on trust in both high and low groups respectively whereas PEEIM presented different paradoxical results in high and low groups. In the relationship between the satisfaction and the trust in the vendor of the high group, PEEIM showed negative moderating effects but in the relationship between the trust and the repurchase intention of the low group PEEIM showed positive moderating effects.
