PURPOSE: The purpose of this study was to investigate the effects of task oriented ADL exercise in different environments in patients with chronic stroke. METHODS: A total of 28 patients with hemiplegia resulting from stroke were included in this study. The patients were randomized into two groups. The control group(n=14) was received neurodevelopment therapy + task oriented ADL exercise and experimental group(n=14) was received neurodevelopment therapy + home based task oriented ADL exercise for 30 minutes twice per week during 6weeks. A task oriented ADL exercise pretest and postest design was used examine the change of FIM(Functional Independent Measure) and K-MBI(Korea-Modified Bathel Index) at the completion of 6 weeks task oriented ADL exercise. RESULTS: After 6 weeks, the experimental group compared with control group showed a significant improvement (p<.05) in FIM and K-MBI scores. CONCLUSION: The results indicate that the home based task oriented ADL exercise improves functions in the persons with chronic stroke.

Fred.E Fiedler는 상황 리더쉽 이론에서 사회 문화적 특성에 따른 Work-style을 근거하여 문화집단을 과업지향적인(Task-oriented) 집단과 관계지향적인 (Relationship-oriented)집단으로 나눈다. 본 연구는 제품사용에 있어 Task를 수행하는 성향의 정도가 제품 인터렉션에 영향을 미칠 것이라는 가설을 세우고, 이를 검증하기 위하여 Fred.E Fiedler의 상황 리더쉽 이론을 근거로 하는 LPC 실험결과의 성향 정도에 따른 제품 사용 인터렉션을 연구한다. Task-oriented 성향과 가까운 문화권 집단은 제품사용에 있어 의도한 목적을 단 시간 빠르게 수행(usability)하는 퍼포먼스의 인터렉션을 중시하고, Relationship-oriented 성향과 가까운 문화권 집단은 제품사용에 있어 목적을 수행(usability)할 때 의미부여(refelctive)적인 측면을 더 중요하게 생각할 것이라는 가설을 증명하기 위한 실험으로 비교적 Task의 의미부여(refelctive)가 동등하고 빈번하게 잘 일어나는 기기인 모바일 단말기 사용에 있어 이 두 집단의 주소록의 주기능과 부기능 사용행태를 비교하고 데이터를 수집, 분석하여 가설을 검증한다. 이 연구결과, 주소록 사용에 있어서 피들러의 상황이론에 의한 Task 수행성향은 모바일 단말기 인터렉션 사용에 영향과의 연관성은 다소 낮게 나타났으며, 관련하여 본 실험 도중 몇 가지 흥미로운 패턴을 발견할 수 있었는데, 이를 기반으로 향후 모바일 단말기의 주소록의 사용자 지향적인 디자인 방향성에 대한 가이드라인을 제시하였다.

The purpose of this study was to assess the feasibility of task-oriented arm training for chronic hemiparetic stroke patients. The experimental design in this study was the pre-test and post-test with control group for 4-week intervention. Thirty patients with chronic hemiparetic stroke were recruited from 2 rehabilitation units. The subjects were divided randomly into experimental and control groups. The experimental group conducted task-oriented approach, involving 3 subparts of upper extremity activities, and the control group involved in the general upper extremity exercises. Functional movements of the upper extremities were assessed using clinical measures, including the Fugl-Meyer Assessment-Upper Extremity Section, Box and Block Test, and Action Research Arm Test. The score of Fugl-Meyer Assessment showed greater increases in the experimental group than in the control group after training. The improvement in Box and Block Test between pre-test and post-test measurements was significantly greater after task-oriented arm training compared to general upper extremity exercises. Action Research Arm Test scores also improved after task-oriented arm training compared to exercises in the control group. The task-oriented arm training improves the gross and fine motor activities and encouraging the use of the paretic arm through activity dependent intervention expedites the recovery of functional activities in the upper extremities for chronic hemiparetic stroke.

Objective: This study was to investigate the effects of Task-oriented training for Gross Motor Function Measure (GMFM), gait and balance function in cerebral palsy. Design: Randomized controlled trials. Methods: Twenty four subjects were recruited by means of a convenience sampling from Kangseo-Gu G rehabilitation center. Subjects were 24 inpatients and were randomly divided into a task-oriented training group and a conventional group. Twelve patients were experimental group who executed the task-oriented training (5 times/wk) for 4 weeks. The task-oriented program mainly focused on the capabilities of independent walking, with the angle of inclination set at 0 degrees and walking at a self-selected comfortable speed. In addition, balance training included the one-legged standing with weight-shifting and task-oriented training. Twelve patients were control group who executed only general conventional therapy (5 times/wk) for 4 weeks. All subjects were evaluated about the motor function, gait and balance function. Subjects have conducted the measured variables, GMFM, GAITRite, PDM Multifunction Force Measuring Plate after treatment. Results: There was statistically significant increase of Gross Motor Function Measure scores of the experimental group and control group after 4 weeks (p<.05). There was statistically significant increase of gait and balance function of the experimental group after 4 weeks of task-oriented training (p<.05). The experimental group showed a significantly improvement in GMFM, gait, and balance compared to the control group (p<0.05). Conclusions: This study proved that task-oriented training after stroke can improve Gross Motor Function Measure, gait and balance. Thus this study can suggest that task-oriented training for gross motor function, gait and balance be effective on the cerebral palsy.

Previous research has shown that the use of self-disclosure, the process of revealing personal thoughts and feelings, in conversational agents (CAs) increases overall user evaluations. However, research exploring the effects of self-disclosure in different situations or dialogue types is limited. This study investigated the effects of self-disclosure and dialogue type (task- vs. social-oriented) on trust, usefulness, and usage intention. Results showed significant interaction effects between self-disclosure and dialogue type. For CAs that did not use self-disclosure, trust, usefulness, and usage intention were higher in task-oriented dialogues. In contrast, CAs that did use self-disclosure had higher trust, usefulness, and usage intention in social-oriented dialogues. These results suggest that researchers and designers should consider the specific dialogue types and corresponding user goals when adding human qualities, such as self-disclosure, to CAs.

Purpose: This study aimed to identify the effects of a task-oriented exercise program on balance in patients with acute stroke. Methods: Twenty participants with hemiparesis resulting from acute stroke volunteered to participate in this study. They were randomly assigned to either the experimental or control group, with 10 patients per group. Both groups underwent a task-oriented exercise program averaging 30 minutes daily for 4 weeks. Balance was assessed before and after the 4-week training period. Before and after the intervention, we conducted a paired t-test to compare the within-group changes and an independent t-test to compare the between-group differences. The statistical significance level was set at p=0.05 for all the variables. Results: Both groups showed significant within-group and between-group changes in balance (p<0.05) after the intervention. Conclusion: This study provides valuable information for future studies in this field. Further research using a larger sample and longer experiment spans can corroborate the results of our study.

Purpose: The aim of this study was to determine the impact of nursing organizational culture types on innovative behavior and job embeddedness among clinical nurse. Methods: For this study a descriptive correlational study design was used. Participants were 293 nurses who had more than one year work experience. They were recruited from two university hospitals, one in Seoul and one in Gyeonggi province in 2016. Collected data were analyzed using SPSS/WIN 21.0 statistics program. Results: Hierarchy-oriented culture was the highest type of organizational culture perception and innovation-oriented culture, the lowest. Multiple linear regression analyses showed that, when age and total clinical experience were adjusted for, innovation-oriented culture perception was the most significant factor influencing innovative behavior, followed by task-oriented culture and relation-oriented culture in that order ($R^2$=.33, F=24.50, p<.001). Relation-oriented culture perception was the factor most influencing job embeddedness, followed by task-oriented culture and innovation-oriented culture in that order ($R^2$=.48, F=55.98, p<.001). Conclusion: More systematic and sustained organizational efforts are required to improve the hierarchy-oriented culture highly perceived by nurses and to emphasize innovation-oriented, relation-oriented and task-oriented organizational culture to increase innovative behavior and job embeddedness among clinical nurses.

PURPOSE: The purpose of this study was to compare task-oriented balance training on stable and unstable surfaces in terms of the fall risk, balance, and gait abilities in patients with stroke. METHODS: Twenty patients with stroke were divided randomly into a stable surface group (SSG, N=10) or unstable surface group (USG, N=10). The participants in the SSG and USG performed task-oriented balance training on stable and unstable surfaces, respectively. All participants were evaluated using the Tetrax, Berg balance scale (BBS), and 10-meter walking test (10MWT) before and after the intervention. Both groups received training 30 min per day, five times per week, for six weeks. RESULTS: The within-group changes in the fall risk, BBS, and 10MWT were significantly different in both USG and SSG (p<.05). USG showed significantly more improvement in the BBS and 10MWT compared to SSG (p<.05). CONCLUSION: Task-oriented balance training on an unstable surface is more beneficial in improving the balance and gait abilities of stroke patients.
