공동작업을 위한 어플리케이션 공유는 여러 시스템에 분산되어 있는 개발도구와 어플리케이션을 공유하여 다수의 참여자가 공간적으로 제약받지 않고 공동 개발할 수 있도록 한다. 그러나 가상공간에 개념을 둔 CSCW에 기존의 어플리케이션 공유 방식을 적용하기에는 3차원이라는 공간적인 요소를 고려하지 않은 문제점을 가지게 된다. 또한 기존의 CSCW에 비해서 가상공간에 기반을 둔 CSCW 어플리케이션 개발은 가상 공간과 다중 참여자를 고려해서 개발하여야 하기 때문에 개발자에게 매우 어려운 작업이다. 따라서, 이 논문에서는 다중 참여자를 지원하는 VRML 기반 어플리케이션 공유 엔진을 설계하였다. 설계된 VRML 기반 어플리케이션 공유 엔진은 참여자 사이트로 에이전트를 이동시켜 웹 브라우져 내의 VRML 가상 공간에서 참여자의 어플리케이션 대한 3차원상의 이벤트를 2차원적인 상대값으로 바꾸고 실제 어플리케이션상의 이벤트로 변환하는 메커니즘을 도입하여 VRML 가상공간에서 어플리케이션을 공유를 가능하게 하였다. 또한 참여자 이벤트를 처리하는 스케줄러를 도입하여 참여자의 이벤트를 순서적이고 참여자 간의 충돌을 해결할 수 있었으며 가상환경이 VRML로 구성되기 때문에 운영체제에 독립적이고 웹상에서 어플리케이션 공유가 가능하였다. 그리고 가상환경을 위한 CSCW 응용 개발에 대한 오버헤드를 줄이고 기존 윈도우 어플리케이션을 가상공간에 사용함으로서 기존 어플리케이션의 재사용성을 높일 수 있었다.

P2P(Peer-to-Peer) 기반에 분산 작업 할당의 경우 정해진 수의 모든 피어에 작업을 분배하는 방식으로 처리하기 때문에 한 피어에 작업량이 증가하는 경우나 피어에 문제가 발생하는 경우 이를 사전에 예측하지 못해 시스템에 문제가 발생하게 된다. 또한 P2P 형태의 특성 상 피어의 그룹 참여는 유동적이며 그룹에 참여하는 피어의 사양도 다양하게 존재하게 된다. 이와 같은 상황에서는 작업을 할당하더라도 작업 진행이 이루어지지 않을 확률이 높아지고 전반적으로 시스템의 성능을 저하시키는 문제점을 가지게 된다. 본 논문에서는 이러한 문제점을 해결하기 위해서 인공지능 알고리즘의 하나인 유전자 알고리즘(Genetic Algorithms: GA)를 활용하여 피어의 상태를 사전에 예측하여 작업 분배 시 동적으로 작업할 피어를 선택하여 처리하는 P2P기반 동적 작업할당 관리자를 설계하였다.

The purpose of this research was to identify the associativity between OTPF and ICF, present the relevance and difference of theoretical concept of OTPF-3 and ICF regarding of the participation and to identify if ICF can explain the professional area of occupational therapy. For this purpose, 4 experts of occupational therapy have made a comparative analysis of the subclassification codes of OTPF-3's work area subsection and of ICF activity and participation. As a result, connecting the most subclassification codes of OTPF-3's work area subsection and of ICF activity and participation, they demonstrated the conceptual similarity and difference. Through this, it is judged to explain the area of occupational therapy with ICF for non-expert and other experts, but it is considered to have limitation to the communication between the experts of occupational therapy. In order to overcome the difference between OTPF and ICF, it would be necessary to have much more researches of comparing widely OTPF and ICF from the perspective of occupational therapy.

Objective : This study aimed to identify common activities with similar participation levels between community-dwelling individuals in the United States (US) and South Korea (Study 1), and analyze the changes in activity participation patterns across the adult lifespan in South Korea (Study 2). Methods : We administered the online survey-based Activity Card Sort version 3 (ACS-3) to adults living in the US and South Korea. In Study 1, we computed the average participation level and visualized 100 activities of the ACS-3 from both the US and Korean samples. The average participation level across the four age groups in Study 2 was calculated and visualized to understand the changes in patterns of involvement across the four ACS-3 domains in a Korean sample. Results : In Study 1, data from 161 Americans and 163 Koreans were analyzed. Of the 100 activities, 48 (instrumental: 20; leisure: 13; fitness/health: 6; social: 9) demonstrated similar levels of participation between the two samples. In Study 2, data from 420 Koreans were analyzed and a tendency for decreased participation with age was found in all domains, except for the instrumental domain. Conclusion : Common daily activities may be used as a means of intervention across cultures in occupational therapy. Protective approaches and support are recommended to optimize older adults' participation in daily life.

Objective: It is important to assess the participation and understand the characteristics of participation for setting goal of the child's treatment and strengthening participation. In this study, we verified the validity of the LIFE-H 1.0, so that domestic occupational therapists can systematically evaluate children's participation. Methods: This study was conducted for about 2 months from February to April 2016 in 47 children with disabilities and non-disabled children. We divided the children into two groups aged 0-4 years and 5-13 years old and conducted a self-report questionnaire to parents. The collected data were verified by SPSS(Statistical Package for Social Science) statistical analysis program. Results: There was no difference between the two groups in general characteristics. In comparison of two groups, a significant difference(p<.05) was found in the LIFE-H 1.0 total performance and satisfaction score and the high discriminant validity was verified. Conclusion: The ultimate goal of occupational therapy is to increase participation. Therefore, the occupational therapist must be able to assess the level of participation and than set the goal of intervention. This study confirms the high level of validity and expects that Korean version of LIFE-H 1.0 will be widely used in clinical field and research.

Objective : The purpose of this study is to investigate the effect of intensive one-day training on Movement Assessment Battery for Children-2 screening developmental coordination disorder. Methods : We provided intensive one-day training which combined lecture and practice on MABC-2 assessment tools for 33 trainees. Interrater reliability was calculated by using Intraclass correlation coefficient (ICC) with the raw score of results scored simultaneously by experts and trainees of MABC-2. Results : The 33 female trainees with an average of five years and three months of experience and less experience using motor skill assessment tools scored raw score while watching the performance scenes of normal children. The results of the ICC between experts and training participants in MABC-2 obtained a high confidence 0.95 and above (p<.001). Conclusion : Clinicians who participated in one-day training seems to use MABC-2 effectively. Through this, one-day training seems to be effective in acquiring new motor skill assessment tools.

Objective : The purpose of this study is to provide evidence for a systematic analysis of occupational therapy interventions for the activity and participation of children and adolescents with developmental disabilities. Methods : The articles used in this study were collected from the RISS, KISS, and DBpia databases. The key words used were "children and occupational therapy" "children and sensory integration," "adolescent and occupational therapy," "adolescent and sensory integration," "developmental disorder and occupational therapy," and "developmental disorder and sensory integration." The research period was limited to January 2008 to August 2018. Seven articles in total were selected for systematic analysis. Results : Most of the included works were single-case studies, and most subjects dealt with the autism spectrum disorder. The majority of the interventions used involved sensory integration. Occupational therapy interventions were self-care (33%), major life area (33%), learning and application (11%), communication (11%), and mobility (11%). Conclusion : This study will help with understanding the current state of occupational therapy interventions for the activity and participation. On the basis of this understanding, various studies on this subject are expected to be conducted in the future.

e-Learning contents are composed of compounding multimedia data. It requires many professionals in contents development stage. The process of e-learning contents development can be seen as a collaborative work. In the perspective of a collaborative work process, the whole process of e-learning contents development would be regarded as collaborative work process for each participant as well as for whole group members. Most of collaborative works in contents development field are widely distributed. Members of work groups require workspaces for sharing information and communicating each other. In addition to workspaces, it also needs to support collaborative reflection such as planning for collaborative work and monitoring for work process. This paper is intended to develop the reflective collaborative work system for e-Learning contents development in order to support the systemic process of e-learning contents development. The reflective collaborative work system is composed of four supportive parts: work flow management, personal workspace, collaborative workspace, and collaborative reflection.
