In order to improve the safety of ship berthing and the efficiency of berth operation in the harbour, the berthing energy acting on a ship in berthing maneuver need to be estimated properly. The berthing energy is used as one of the criteria to determine the maximum permissible load q{ fender as well as important factors to establish the berthing speed and the required power of tug-boat for pilot and ship operator. Some problems of berthing energy are discussed on the basis of the hydrodynamic aspects. Then, series calculations of berthing energy are carried out considering the effect of water depth on added mass and the ship shape for container series from 1,600TEU to 12,000TEU.

The work of VLCC SPM mainly is accomplished on the open sea. On the open sea as a result of meteorological condition and the ocean wave influence, When the weather condition is get bed, peremptorily moving to the safety place, bemuse of the gale and the billow, almost happened frequently, the pilot is unable to go on board and the tug is also unable to be used Now bemuse of the bad weather the VLCC SPM moving to the other safety place frequently happened in the ulsan port. the construction of new harbor, it constructed many break water around SPM. So that it is necessary to propose the new standard about how to maneuvering area actually. Now our country is at the blank stage about the establishment of SPM research Most of the situations refer to overseas standards. But these standards lack consistency and clarity. So when moving to the another safe place from SPM, we must Carry through the research and study on the ships using sailing through AIS Data We must put forward a new standard about maneuvering area of ships moving at SPM.

Purpose : This study was performed as follows in order to investigate the effect of presynaptic inhibition mechanism using the transcutaneous electrical stimulation (TES) for global synkinesis (GS) on the post-stroke hemiplegic patients. Methods : The subjects consist of 38 post stroke hemiplegic patients; experiments were performed on thirty patients excluding eight. The experiment was performed on sham group, sensory level stimulation group, and motor level stimulation group for 20 minutes a day 5 times a week for 6 weeks total. We compared the differences in GS levels and walking ability. The measurements were carried out pre, immediated, post 10th, and 20th, for a total of four measurements. Results : The GS level using sEMG found significant differences between groups at the post 10th and post 20th in dorsiflexion, and post 20th in plantarflexion (p<0.05, p<0.01). The motor level group indicated more significant differences when the number of electrical stimulations increased. TUG and 10 m walking test indicated a significant difference at immediated, post 10th, and post 20th. The motor level group showed more significant decreasing tendency than the sensory level group. Conclusion: From these results, electrical stimulation using presynaptic inhibition mechanism of transcutaneous electrical stimulation (TES) had positive effects for walking ability on inhibition of muscle tone in lower extremity. The motor level stimulation group experienced a more significant effect than the sensory level stimulation group. Therefore, the transcutaneous electrical stimulation (TES) is considered to be effective on walking ability increasing through inhibition of muscle tone in lower extremity for rehabilitation of post stroke hemiplegic patients.

This study to investigate the effects of proprioceptive motor program on proprioceptive and balance ability for patients with chronic stroke. Twenty nine subjects were recruited by means of a convenience sampling from Gyeonggi-do B hospital. The subjects were divided into two group: a proprioceptive motor program and general physical therapy(n=15), general physical therapy(n=14). The stimulation and exercises were conducted for 30 min per day, three days, per week for six weeks. All participants were assessed before and after taping training using proprioceptive, berg balance scale(BBS), timed up and go test(TUG), and balance ability was measured using a BioRescue. After training, the change values of the proprioception and balance ability in experimental group were significantly greater than control group(p<0.05). This findings show that progressive and proprioceptive motor program training convergence can be effective for stroke patients proprioception and balance ability. Continued development of convergence interventions for chronic stroke patients with proprioception and balance ability in the practice are suggested.

This study examines changes in walking ability among patients with stroke after applying dual-task training under the condition of visual control and unstable supporting ground; the purpose is to provide reference data for selecting intervention methods that enhance the walking ability of patients with stroke. Among the patients with stroke who received rehabilitation treatment(at Rehabilitation Hospital B in Gyeonggi, South Korea from May 2014 to July 2014), 29 patients were selected as research subjects; all of them understood the purpose and contents of this research and agreed to participate in the experiment. The research subjects were divided into a visual control and unstable supporting ground dual-task(VUDT) group(10 patients), a visual control dual-task(VDT) group(10 patients), and an unstable supporting ground dual-task(UDT) group(9 patients); all of the subjects received 30-minute trainings, three times a week for a total of four weeks. A Timed-Up-and-Go(TUG) test was performed to investigate the change of walking function among the subjects, and a 10m walking test was conducted to measure their walking speed. According to the study results, all three groups showed significant differences after dual-task training; the dual-task training group under the condition of visual control and unstable supporting ground showed the most prominent change. This study confirmed that dual-task training using visual control and unstable supporting ground has a positive impact on the walking ability of patients with stroke. Through the study results, we found that implementing dual-task training under the condition of visual control and unstable supporting ground can more effectively improve the walking ability of patients with stroke, rather than performing visual control dual-task training or unstable supporting ground dual-task training only.

Purpose : This study was to evaluate the effect of traditional balance training on balance in older adults. Methods : The subjects of this study were thirty elderly over 65 years old. Thirty subjects ranging aged from 66 to 85($74.0{\pm}5.83$) completed the study and participated three times a week for 5weeks. Subjects were assessed by utilizing two different balance measure : Static standing balance was measured by balance performance monitor(BPM). Dynamic balance was measured by timed up and go test(TUG). The scale for static standing balance was measured by using frequence(Hz), sway area($mm^2$), sway path(mm), max sway velocity(mm/s), ant/post sway angle($^{\circ}$), left/right sway angle($^{\circ}$), and sway number. Results : The change in frequency were statistically significant on pre-test and post-test(P<.05), 2. The change in sway area were statistically significant on pre-test and post-test (P<.05), 3. The change in sway path were statistically significant on pre-test and post-test(P<.05), 4. The change in max sway velocity were statistically significant on pre-test and post-test (P<.05), 5. The change in ant/post sway angle were statistically significant on pre-test and post-test (P<.05), 6. The change in left/right sway angle were statistically significant on pre-test and post-test(P<.05), 7. The change in sway number were statistically significant on pre-test and post-test(P<.05), 8. The score on timed up and go test shows statistically significant increase on pre-test and post-test (P<.05). Conclusion : This study suggest that traditional balance training have an effect on balance performance ability for elderly people. Therefore, the traditional balance training is recommended for older adults to improve balance performance ability.

PURPOSE: This study compares the effects of HUBER rehabilitation and general rehabilitation treatment on the coordination, balance, and walking ability of stroke patients. METHODS: This study enrolled 38 randomized stroke patients, and data was collected for 6 weeks. All participants were randomly assigned to either the experimental group (n = 19) or control group (n = 19). The experimental group were administered Huber rehabilitation and general rehabilitation treatment. The control group was given only general rehabilitation treatment. Both treatments were conducted for 30 minutes during each training session, 3 training sessions per week, for 6 weeks. The coordination, balance, and walking ability were evaluated before and after the intervention, to compare the intergroup and intragroup changes. RESULTS: Change in the right LOS (limit of stability) (p < .001) and forward LOS (p < .02) following intervention were significantly greater in the experimental group than in the control group, but no significant group difference was observed between left LOS (p > .1) and backward LOS (p > .2). Alterations in coordination (p < .02) and TUG (p <. 05) were significantly greater after intervention in the experimental group than in the control group. CONCLUSION: These findings suggest that HUBER rehabilitation is effective in improving the coordination, balance, and walking ability in stroke patients. To strengthen and validate the results of this study, future studies related to HUBER rehabilitation are required.
