  • The notable feature of the Cu(II) coordination polymer investigated here is its ability to self-assemble into a double-stranded helical structure with regular grooves along the helical axis, through the combination of metal-chloride dimeric interactions and repulsive interactions, as an organizing force. It is also remarkable that the double-stranded helices self-organize into a 2-D columnar structure in both the bulk state and aqueous solution. These results represent a unique example that weak metal-ligand bridging interactions can provide a useful strategy to construct stable double-stranded helical nanotubes.

  • In this paper, we study the distributed coordination of a set of synchronous, anonymous, memoryless mobile robots that can freely move on a two-dimensional plane but are unable to communicate directly. Based on this model, we analyze the application problem that consists in having a group of robots form a barricade line to protect from car traffic a crowd of demonstrators parading on the street. For the sake of robustness, we privilege fully decentralized solutions to the problem. In particular, we give a self-stabilizing distributed algorithm to address the problem, in this presentation

  • Purpose : This study aims to investigate the effect of somatosensory stimulation on the upper limb sensory and function and self-esteem of stroke patients. Methods : This study period was march 4 to april 4 (5 weeks). The subject were 20 stroke patients with somatosensory impairment in B hospital, seongnam, gyeonggi province. They were devided into two group-experimental and control-with 10 members each. The members of the experimental group underwent somatosensory stimulation, whereas the members of the control group underwent an occupation-based intervention for 5 weeks. Thirty-minute therapy was provided 3 times per week for 5 weeks. Before and after the intervention, both groups were evaluated via light touch, static two-point discrimination, stereognosis, Fugl-Meyer assessment (FMA), and self-esteem scale Results : In this study, light touch was not significant in both groups. Static two-point discrimination was significant among the experimental group member's index fingers. Among the control group members, it was significant in the ring finger. The comparison between the two groups was significant in the index finger. The stereognosis results were significant in the experimental group but not in the control group. The comparison between the groups after the intervention was not significant. FMA was significant in the shoulder/ elbow/ forearm (SEF), hand and coordination among the experimental group. Among the control group, it was significant in the SEF and hand. The comparison between the groups was significant in the SEF, hand and coordination. The self-esteem scale results were significant among both groups, and the comparison between the group's score was likewise significant. Conclusion : In conclusion, somatosensory stimulation therapy increases the static two-point discrimination, stereognosis, upper extremity function, and self-esteem of patients with stroke. Therefore, while somatosensory stimulation therapy is not the best therapy, it is one of the best occupational therapies for stroke patients.

  • Objective : This study was conducted to examine self-selected goals and the outcome measures used in the Cognitive Orientation to daily Occupational Performance (CO-OP) approach for Developmental Coordination Disorder. Methods : Studies published from January 2012 to October 2022 in the PubMed, Embase, ScienceDirect, Cochrance Library databases were searched. Keywords used for search were ('developmental coordination disorder' OR 'DCD') AND ('Cognitive Orientation to daily Occupational Performance' OR 'Cognitive Orientation to Occupational Performance' OR 'CO-OP'). Among 211 searched studies, 7 selected studies that match the thesis of this study were analyzed. Results : The selected studies showed a relatively high level of evidence overall, including two randomized experimental studies, one non-random two-group study, three non-random one-group studies, one single-subject study. The self-selected goals preference of the children was high in the order of play, education, and daily life activities. Most of applicable sessions were conducted 10 times during a 1-h period, and intervention effects showed positive outcomes on the occupation performance motor domain. To measure the effectiveness of CO-OP, the improvement of occupational performance was evaluated using Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS), and the improvement of motor skills was evaluated using Movement Assessment Battery for Children (M-ABC). Conclusion : This study is expected to be used as basic clinical data when applying the CO-OP approach to Developmental Coordination Disorder.

  • Purpose: The purpose of this study was to identify role through job analysis (duties and tasks) of nurses who work as clinical nurses with education and clinical nurse with patient coordination within the hospital. Methods: The DACUM committee was organized with 8 nurses each, clinical nurses with education and clinical nurses with coordination. The committee derived the duties and tasks of the two groups of clinical nurses from their actual work in the hospital through a DACUM workshop. Validity of the derived duties and tasks was tested by 12 nurses at each of 3 hospital. Results: For clinical nurse with education, 8 duties and 45 tasks were identified, which included patient education and consultation, patient advocacy, management of the therapeutic process, direct nursing care, activities work directed at improvement, management of health promotion events, administration work, and self-improvement. For clinical nurse with coordination, 10 duties and 54 tasks were identified, and included client consultation, client education, direct nursing care, coordination of therapeutic flow, employee education, public relations with the community, planning and operation of meetings, administration work, work directed at improvement, and self-improvement. Conclusion: The results of this study contribute to not only the work of the participants but also basic data for human resource management in the hospital.

  • Under the coordination of GKSS a new European project in the field of membrane development started recently. This project focuses on the development of novel nanostructured materials for selective material transport and separation. Two classes of materials will be developed in this project: nanostructured organic/inorganic hybrid materials and functional self-organized supramolecular copolymers.(omitted)
