Purpose: The purpose of this study was to verify the effect of applying clam exercise on improving trunk control and balance ability in stroke patients. Based on this, we tried to provide clinical information. Methods: In this study, 18 patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a clam exercise group (9 patients) and a control group (9 patients). After 30 minutes of neuro-development therapy, they performed clam exercise or bridge exercise for 3 weeks, 5 times a week for 30 minutes. A trunk impairment scale (TIS) and a postural assessment scale for stroke patients-trunk control (PASS-TC) were performed to evaluate the subjects' ability to control trunk before and after intervention. Balance ability was measured by Balancia before and after intervention. Results: After the training periods, area 95% COP and weight distribution of the affected side were significantly different from the clam exercise group compared to the control group (p<0.05). Conclusion: Based on the results of this study, in can be seen that the clam exercise is effective in improving the balance ability compared to the bridge exercise. Maintaining the standing posture requires muscle strength of the hip abduction and extension, which is the result of the clam exercise selectively strengthening these muscles. Therefore, if you want to provide intervention to improve the balance of stroke patients, it is recommended to perform a clam exercise.

Background: Stroke patients have leg muscle weakness and impaired balance resulting in compensatory changes. To restore balance in these patients, functional training using postural strategy is needed. Objective: To examine the effects of ankle and hip strategy training on the center of pressure (COP) movement and limits of stability (LOS) in standing posture in stroke patients. Design: The study was an assessor-blinded and randomized-controlled clinical trial. Methods: Thirty patients were randomly assigned to an ankle strategy training group and a ankle/ hip strategy training group. Patients in the ankle strategy training group underwent ankle strategy exercise for 30 min, and those in the ankle/ hip strategy training group underwent 15 min of ankle strategy exercise and 15 min of hip strategy exercise. Both groups underwent training thrice a week for four weeks. Forward, backward, paretic side, and non-paretic side COP movements and LOS were measured using BioRescue. Results: After the intervention, except for the backward area in the ankle strategy training group, the COP movement area and the LOS were significantly improved in both the groups. In addition, these improvements were significantly higher in ankle/ hip strategy training group than that in the ankle strategy training group. Conclusions: Ankle strategy training in addition to hip strategy training improves COP movement (forward-backward, paretic side area, and non-paretic side area) and LOS in stroke patients.

Background: This study was to investigate the relationship between scapular downward rotation ratio (SDRR), lower trapezius (LT) muscle, and rounded shoulder angle (RSA) on each side in subjects with scapular downward rotation syndrome (SDRS). Design: Cross-sectional Study Methods: Fifteen subjects have participated in this study. The RSA and SDRR were assessed using a tape measure in standing posture. The RSA was computed by the angle made by two lines: one was the distance between the root of the scapula and the acromion, and the other was the distance between the acromion and the horizontal line in the root of the scapula. The SDRR was computed by two horizontal lines: one was the distance between the mid-line and root of the scapula, and the other was the distance between the mid-line and inferior angle of the scapula. LT muscle strength was performed in a prone position by the hand-held dynamometer. Results: There was a positive correlation between SDRR and LT strength in the less affected sides (r=.59; p=.02), however, there was no correlation between RSA and LT strength in the more affected sides (p>.05).

Through this research, the current state of naval coordination and guidance of shipping is reviewed whereupon which a suggestion is made for a novel role which satisfies the needs of the people and the country asked of the Navy. Taking into consideration the dynamic security environment, the developing relationship between the two nations on the Korean peninsula, and the influence that the Republic of Korea has on maritime security, it is made more urgent that the Navy takes a proactive course of action in terms of naval coordination and guidance of shipping. The current form of Korean naval coordination and guidance of shipping is adapted from the logical and flexible concepts of NCAPS and NCAGS and is one of many tasks that the Republic of Korea Navy must perform. However, when the Republic of Korea Navy develops blue-water capabilities with the ambitions of protecting its people and their way of life, naval coordination and guidance of shipping could potentially become one of the primary functions of the Republic of Korea Navy that the it must champion. Already, there are indications that foreign navies are, through many developments and commitment towards naval coordination and guidance of shipping, protecting its people and states' interests wherever is necessary. In the case of Chile, its Navy has taken the helm of naval coordination and guidance of shipping and has integrated various maritime organizations including the coast guard and the National Customs Service for the sake of maintaining regional maritime security, showing immediate force if necessary. Presently, as the Republic of Korea Navy looks to be a global naval power, it is important that a reprioritization of the Navy's mission is undertaken, all the while sustaining military readiness posture on the Northern Limit Line. It cannot be any more emphasized how crucial thorough military readiness posture is as a natural stance against the enemy. That being said, contributing towards international maritime security is consistent with the nation's standing. It is a fact that maritime security has been conceptualized and developed merely as a study within the Ministry of Maritime Affairs and Fisheries, the Republic of Korea Navy, and other governmental organizations, forces, and academia. Naval cooperation and guidance of shipping suggested by this research as a practical operational field is a concrete solution to what once was an abstract concept. To stand firm on its status as a maritime nation, the Republic of Korea must establish a Maritime Security Organization within its Navy and develop the appropriate doctrines. Attaining experts, developing doctrines, and cultivating the capability to deploy maritime forces will allow for the Republic of Korea to execute a primary role in keeping international maritime security and naval coordination and guidance of shipping. To fully achieve its latent potential necessitates the Republic of Korea Navy to expedite the introduction of naval coordination and guidance of shipping concepts and to establish the appropriate doctrines, operation plans, and organizations.

This paper asks whether the Republic of Korea (ROK) Navy should continue to focus on building ocean-going naval ships when it faces the threats of North Korean provocations in littoral areas. My position is that the ROK Navy should keep pursuing ocean-going capabilities. I provide explanations why it should do so from the perspectives of three important dimensions: capability, doctrine, and organizational identity. First, I argue that the distinction between a littoral navy and an ocean-going navy is an unnecessary dichotomy. It may lead to inefficiency in national security. The military posture should be designed in a way that it can address all external threats to national security regardless of whether they are from North Korea or not. Such capability is the one that the ROK Navy has tried to acquire with the 'Blue Water Navy' initiative since the 1990s. Second, also from the perspective of lately developed military doctrines that emphasize jointness and precision strike capability, ocean-going capabilities such as the mobile task fleet program have become a must, not an option, given today's security situations on and around the Korean peninsula. Lastly, I draw attention to the fact that the 'Blue Water Navy (BWN)' initiative meant more than just capability to the ROK navy. The BWN represents the ROK navy's organizational identity that the navy has defined since the 1980s as it emphasized promoting national interest and international standing as part of its organizational essence. Furthermore, the phrase 'blue water navy' took on symbolic meanings to the people that are associated with South Korean-ness including sovereignty, national pride, standing in the world and hopes for the future. Since 1990s, many scholars and experts have made the case for the necessity of improving South Korea's naval capability based on different rationales. They emphasized the protection of Sea Lines of Communication (SLOCs), the economic value of the sea, the potential danger associated with territorial disputes over islands, and increasing naval power of neighboring countries since the end of the Cold War. This paper adds to this debate by trying to explain the matter with different factors including naval doctrines and organizational identity. Particularly, this paper constitutes a unique endeavor in that it incorporating constructivist elements (that is, identity politics) in explaining a national security matter.

Multiple system atrophy is a neurodegenerative disease that causes diverse bodily dysfunctions (cerebellar, pyramidal, automatic, and urological, in any combination), as well as Parkinsonism. Patients with multiple system atrophy commonly display antecollis, a condition where the patient's head tilts forward more than 45 degrees. Despite its common occurrence in these patients, no current standardized therapies are effective for treating antecollis. In this study, Korean medicinal treatments, including Chuna manual therapy, pharmaco-acupuncture, bee venom acupuncture, acupuncture, herbal medicine, and moxibustion therapy, were administered to the patient over a 27-day period. After the treatment, assessments of the head position on the EPIS-PD scale (Part I) and at a standing position from the side (Part II) both revealed improvements. As the head flexion angle decreased, the patient's head posture improved, as determined by a decrease in angle from 80 degrees to 30 degrees in the upright, standing position. As a result, patients who previously were unable to walk without the support of walking frames could now roam freely and independently, with significant increases in both walking speed and distance. In essence, this study suggests that Korean medicine is an effective treatment for patients with multiple system atrophy who suffer from antecollis and gait disorders.
