The purpose of this study is to examine the effect of higher grades in elementary the science process skill, academic achievement and teaching learining perception by Digital Text-book in elementary science lesson. To verify research problem, the subject of this study were sixth-grade students selected from two classes of an elementary school located in Ulsan : the experimental group is composed of thirty-one students who were participated in Digital Text-book, and the other is composed of thirty students(comparison group) who were participated in teacher map based learning situation. During eight weeks, Digital Text-book instruction was executed in th experimental group while the teacher map based instruction in controled group Post-test showed following results: First, the experimental group showed a significant improvement in the science process skill compared the comparison group. Second, the experimental group did not showed a significant improvement in the Acdemic Achievement compared th the control group. Third, the experimental group showed a significant improvement in the teaching learning perception compared the comparison group. In conclusion, Digital text-book model was more effective than the teacher map based teaching model on science process skill and teaching-learning perception. However, since the study has a limit on an objet of the study and the applied curriculum, the additional studies need to be conducted with an extended comparative group and curriculum.

Purpose : This study aimed to investigate how neuromuscular electrical stimulation (NMES) affects the balance ability of patients who have undergone total knee arthroplasty owing to osteoarthritis. Methods : Thirty patients who had undergone total knee arthroplasty were randomized to an experimental group (n=15) and a control group (n=15). The experimental group received conventional physical therapy for 50 minutes and NMES treatment for 30 minutes, whereas the control group received conventional physical therapy for 50 minutes and active range of motion (AROM) exercises for 30 minutes. Within-group and between-group changes in static and dynamic balance ability before and after the 4-week intervention were analyzed. Results : In the within-group comparison, sway velocity in the center of gravity and total distance were significantly improved in both the experimental and control groups (p<.05), with no significant differences between the groups (p>.05). In the within-group comparison, both the experimental and control groups showed significant improvement in the functional reach test and movement velosity (p<.05). In the between-group comparison, the experimental group showed a significantly better improvement than the control group in the functional reach test (p<.05), but there was no significant difference in the movement velosity test (p>.05). Conclusion : In this study, NMES improved the static and dynamic balance in patients who had undergone total knee arthroplasty. Compared with AROM exercises, there was a greater effect on dynamic balance partially; however, the overall effect was similar. Therefore, NMES may be one option among various interventions to improve the balance ability in patients who have undergone total knee arthroplasty. In particular, this method may be effective when it is difficult to apply balance training for patients with total knee arthroplasty in a clinical setting.

This study aims to reveal the impact of continuous antagonist strengthening(CAS) and Evjenth-Hamberg stretching(EHS) on the cervical mobility in the university students with abnormal transformation of forward head posture(FHP). Our experiment was conducted 3 times a week for 6 weeks in a total of 20 individuals : continuous antagonist strengthening(CAS) group(n=10) & Evjenth-Hamberg stretching(EHS) group(n=10). In a pre and post comparison, both CAS group and EHS group appeared significantly in mSBI and SBA(p<.05) and the two-group comparison showed a significant difference(p<.05) : CAS group showed better effects. Thus, it is considered that the combined use with continuous antagonist strengthening(CAS) had better effects for cervical mobility than Evjenth-Hamberg stretching(EHS) alone.

Purpose: The purpose of this study was to examine the effects of spinal decompression therapy on pain and disability in patients with chronic low back pain. Methods: Twenty patients with chronic low back pain were divided into an experimental group (spinal decompression therapy, n=10) and a control group (conservative physical therapy, n=10). Both groups were treated three times a week over a four-week period. Results: The comparison of between-group changes post-treatment revealed statistically significant lower levels of pain and disability in the experimental group than the control group. The comparison of within each group changes before and after the treatment showed statistically significant declines in pain and disability indexes of both groups. Conclusion: Spinal decompression therapy may be an effective intervention for improving pain and disability in patients with chronic low back pain.

Purpose: To identify the effect of knee joint traction therapy on pain, physical function, and depression in patients with degenerative arthritis. Methods: In total, 30 patients with degenerative arthritis were randomly assigned to one of two groups: the experimental group, who underwent knee joint traction therapy, and the control group, who underwent general physical therapy (15 patients per group). Pain was measured using the visual analogue scale (VAS), physical function was measured using the Western ontario and McMaster universities osteoarthritis (WOMAC) index, and depression was measured using the Beck depression inventory (BDI). The VAS, WOMAC score, and BDI score were recorded before and after the 4-week treatment. Results: As a result of comparison within groups, the experimental and control group showed significant difference for VAS, WOMAC and BDI after the experiment (p<0.05). In comparison between the two groups, the experimental group in which knee joint traction was applied showed more significant change in VAS, WOMAC and BDI than the control group (p<0.05). Conclusion: This study showed that knee joint traction therapy was effective in improving pain, physical function, and depression in patients with degenerative arthritis.
