  • This research deals with an object-oriented task description(OOTD) method to solve problems such as being hard to understand and a lack of description in existing task description methods. The OOTD method includes an object-oriented task structure diagram and an object-oriented task attribute diagram. The former shows some relationship between a task and a derived task. The latter includes important attributes to define each task. Finally, a sample case is introduced to show how efficient these two diagrams are for the task description.

  • The contingency theory of leadership was proposed by F. Fiedler. In his theory, he divided the group into Task oriented and Relationship-oriented people based on work-style by LPC(Least Preffered Co-workers) test. This survey searches significance of interaction usage depending on which group has more aggressive interaction on the address list with mobile phones focusing on the differences between mainfunctions (name, cell phone, group name) and sub-functions (birthday, Photo, E-mail). Itis the hypothesis that the relationship-oriented group has more interaction than the task-oriented group which was identified through the analyzed usage of the address list. Results show that the contingency theory was not appropriately related with the research. Interaction usage by the following task based on Fiedler's contingency theory of leadership isn't related much. However, by discovering the interesting patterns by the test, this research is able to guide human-centered address design directions.

  • This paper analyzes 96 Korean companies to illustrate the relationship between the knowledge management strategies and task characteristics. Knowledge management strategies can be categorized as being codification- and personalization-oriented. Task characteristics are analyzed from the perspective of content-oriented, process-oriented, number of exceptions, and analyzability. These results illustrate how companies should align the knowledge management strategies with task characteristics. It is found that codification strategy is more likely to be associated with high content-oriented and high analyzability task, and personalization strategy is with high process-oriented task. The survey result confirms that managers should adjust knowledge management strategies in view of the characteristics of the task.

  • 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.

  • 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.

METHODS: Forty stroke patients were randomly allocated into a task oriented training group (TTG, n = 20), a virtual reality training group (VRG, n = 20). Both groups received the usual physical therapy. In addition, TTG patients underwent task training such as sweeping the table, cup stacking, carrying wood block. VRG patients underwent virtual reality training using X-box kinect. Both groups received 30 minutes of training per day, five times per week, for twelve weeks. RESULTS: After intervention, both groups showed significant improvement on upper extremity function, balance ability, and depression. VRG showed more improvement on upper extremity function, balance ability, and depression than TTG. CONCLUSION: According to the results of this study, task-oriented training and virtual reality training are feasible and suitable for stroke patients. And virtual reality training is more effective method than task oriented training.
