동북아시아에서는 '바큇살 구조'라 불리우는 미국 중심의 양자동맹체제가 지속되고 있다. 그러나 최근 급변하는 동아시아의 국제정세와 이에 대응하기 위해 국가들 간 다각도로 협력하는 양상들을 보았을 때, 이러한 동맹체제의 변화 가능성에 대해서 진단해 볼 필요성이 제기되었다. 따라서 본 연구에서는 주 위협, 위협의 강도, 국가 간 신뢰도라는 요인을 바탕으로, 유럽과 동남아시아의 집단안보체제에 관한 사례연구 및 비교분석을 통해 이에 대한 영향을 분석하였다. 본 연구는 이를 바탕으로 동북아에서의 안보체제 변화 가능성에 대해서 연구를 진행하였으며, 현재의 갈등이 지속적으로 악화된다면 동북아를 넘어 동아시아 전반에서의 집단안보체제가 형성될 가능성이 분명히 존재한다고 보았다. For the last 70 years, the U.S.-led bilateral security system, or "Hub-and-Spokes" system, has been applied to Northeast Asia, and the system has been successfully settled in terms of stability and economic achievements of the region. Given the increasing complexity of the security environment of East Asia, it is plausible to consider the possibility of a security system shift from bilateral alliances to collective security. In order to analyze the driver of collective security system, this study developed three factors of formation and development of collective security system - main threat, intensity of the threat, and confidence among countries in the system - by reviewing international political theories related to security cooperation. Comparing the formation, development, and achievements of NATO and SEATO, the study figures out that the existence of the main threat, the high intensity of the threat, and the strong confidence among countries in the security system are the primary drivers for a successful collective security system. Based on the result, the study also analyzed the possibility of a security system shift in East Asia. Considering contemporary international conflicts such as U.S.-China strategic competition, Russia-Ukraine War, and growing threats posed by North Korean nuclear and missiles, the study anticipates that the necessity of a collective security system that will replace the current security system of the region would arise. Still, although some issues between countries should be overcome, the growing intensity of the threats will promote cooperation among countries by improving their confidence.

중동 국제관계에 대한 구조적 관점에서의 이란 해양전략에 대한 분석: 방어적 현실주의 관점을 중심으로

오동건,Oh, Dongkeon 한국해양전략연구소 2020 해양안보 Vol.1 No.1

2019년 5월과 6월, 호르무즈 해협에서 상선들의 연이은 피격으로 호르무즈 해협에서 해양안보의 불확실성은 증대되고 다수 국가들이 관심을 가지고 역내 안정을 도모하려 노력하고 있다. 한국도 청해부대 임무구역 확장이라는 독자적인 형태로 호르무즈 해협인근의 해양안보 안정화를 위해 노력 중이나, 호르무즈 해협의 주요 역내 행위자인 이란에 대한 세부적인 연구는 미진한 상황이며, 이란 또한 공식적으로 자국의 해양전략을 발표한 바가 없다. 따라서 본 연구는 현실주의적 시각, 특히 케네스 월츠로부터 시작된 방어적(구조적) 현실주의의 관점에서 아랍-페르시아의 양극체제로서의 중동의 정세를 분석하고, 아울러 이란의 독특한 이중화된 군 구조와 구분된 역할, 그리고 전력구성을 연구함으로서 이란의 국가전략과 해양전략을 도출하였다. Four cargo ships were ambushed by bombs in 2019 while navigating in the Strait of Hormuz. It was not clear who attacked those ships, however, many nations including the United States argued that it was Iran due to several reasons. The United States established the maritime collective defense system named International Maritime Security Construct (IMSC) in order to protect the maritime security in the Strait of Hormuz, without disclosure against whom it is aimed. Persian, who uses the Persian language unlike other countries in the Middle East, is the major ethnic group in Iran, and most of them believe Shi'ah Islam while most of the Arabs in the Gulf countries adhere to Sunni Islam. It seems that historic and religious motives caused the bipolar system in the Middle East, however, it is plausible to analyze the system of international affairs in the Middle East via defensive or structural realism. Iran has attempted to maintain its hegemony in the region by supporting Shi'ah muslims in the neighboring countries as well as in the world by using military and economic means. In this context, Iran's maritime strategy is to maintain its maritime hegemony on the Persian Gulf via countering threats and cooperating with friendly navies by using the Islamic Republic of Iran Navy(IRIN) and the Islamic Revolutionary Guard Corps Navy(IRGCN). IRIN acts like other navies in the world: protecting national interest at sea, expending its operational areas to the outer seas, and enhancing cooperation with other navies. Meanwhile, IRGCN plays a role as an asymmetric force at sea. It is composed of small and fast asymmetric assets, which can ambush ships fast and furious. Considering the poor study for Iran's maritime strategy in Korea, analyzing the strategy is meaningful for the Republic of Korea Navy, which has operated the Cheonghae Unit for more than ten years since it has extended its operational area over the Strait of Hormuz. In order not to be drawn into the conflict in the Strait, research on the maritime strategy of Iran and other countries in the Middle East should be started.

PNF 탄력밴드 운동과 중추신경계 발달 운동이 뇌졸중 환자의 일상생활체력과 근활성도에 미치는 영향

This study was designed to investigate the effects of elastic band exercise using proprioceptive neuromuscular facilitation (PNF) and central nervous system (CNS) -stimulating exercise on functional fitness and electromyograph (EMG) in hemiplegic stroke patients. Fourteen hemiplegic stroke patients were divided into elastic band exercise using PNF group (PNF group; n=7) and CNS-stimulating exercise group (CNS group; n=7). Subjects in PNF group and CNS group performed elastic band exercise and CNS-stimulating exercise, respectively, for 30 min/session, five times/wk, for four weeks. Functional fitness and EMG were measured and compared between groups and between pre- and post-test. Main results of the present study were as follows: 1) Knee flexion, arm curl, and sit-and-reach increased significantly in PNF group and CNS group. Knee extension, standing up and sitting down a chair, and functional reach increased significantly in PNF group, whereas 2.44m up and go improved significantly in CNS group. 2) All variables regarding EMG increased significantly in PNF group and CNS group, and the increment rate was higher in PNF group than CNS group. It was concluded that elastic band exercise using PNF would be more beneficial to improve muscular strength, muscular endurance, static balance, and strength of vastus medialis than CNS-stimulating exercise. Therefore, elastic band exercise using PNF could be very effective alternative method to treat hemiplegic stroke patients.

Bobath 개념에 기초한 치료적 운동이 뇌졸중으로 인한 편마비 환자의 일상생활 수행능력, 균형능력 및 관절가동범위에 미치는 영향

This study investigated the effects of therapeutic exercise developed based on Bobath concept on activities of daily living, balance ability, and range of motion (ROM) in hemiplegic stroke patients. Subjects in general therapeutic exercise group (GEN group; n=10) and Bobath conceptional therapeutic exercise group (Bobath group; n=10) exercised their assigned exercise for 30 min/session, five times/wk, for four weeks. Variables related to activities of daily living, balance ability and ROM were measured and compared between groups and between pre- and post-test. Main results of the present study were as follows: 1) Sit to lie, lie to sit, and sit to stand improved significantly in GEN group, whereas all variables regarding activities of daily living improved significantly in Bobath group. 2) BBS increased significantly in both group, whereas TUG did not changed significantly in both groups. 3) ROM for shoulder flexion, shoulder abduction, hip flexion, hip flexion with knee extension, hip abduction, hip internal rotation, and ankle dorsiflexion increased in both groups; however, Bobath group showed higher increments than GEN group in these variables. It was concluded that therapeutic exercise developed based on Bobath concept was more effective in improving activities of daily living, balance ability, and ROM of hemiplegic stroke patients than general therapeutic exercise.

카이로프랙틱과 PNF의 병행치료가 앞쪽머리자세 환자의 척추정렬상태와 체격에 미치는 영향

오동건(Oh, Dong-Gun),한상진(Han, Sang-Jin),성순창(Sung, Soon-Chang) 한국웰니스학회 2017 한국웰니스학회지 Vol.12 No.3

본 연구는 카이로프랙틱 치료와 propriocepeive neuromuscular facilitation(PNF) 패턴의 병행치료가 앞쪽머리자세 환자의 척추정렬상태(허리앞굽음각, 골반변위)와 체격(신장, 체중, 그리고 신체질량지수)에 미치는 영향을 규명하는 것이었다. 앞쪽머리자세 환자 30명을 카이로프랙틱 치료 집단(n=10), PNF 패턴 집단(n=10), 그리고 카이로프랙틱+PNF 병행치료 집단(n=10)에 무선할당 하였으며, 각 집단별로 일일 25분, 주 3회, 10주간 해당 프로그램에 참여하도록 하였다. 치료 전과 후에 각각의 종속변인을 측정하여 집단간, 그리고 검사 간에 비교하였다. 그 결과 세 집단 모두에서 모든 종속변인이 유의하게 변화된 것으로 나타났으며, 카이로프랙틱+PNF 병행치료 집단에서 다른 두 집단에 비하여 그 변화의 양상이 더 높은 경향이 나타났다. 각각의 처치 모두 앞쪽머리자세 환자의 척추의 정상적인 배열상태와 체격요소의 이상적인 개선을 위한 효과적인 중재방법이라고 사료되며, 특히 카이로프랙틱+PNF 병행치료가 보다 유익한 처치로 판단된다. This study was designed to investigate the effects of combined treatment of chiropractic therapy and proprioceptive neuromuscular facilitation(PNF) patterns on lumbar lordosis angle(LLA), pelvic discrepancy(PD), height, weight, and body mass index(BMI) in forward head posture patients. Thirty forward head posture patients volunteered to participate in the study as subjects, and were divided into one of three groups, i.e., chiropractic therapy group (Chiropractic group; n=10), PNF patterns group (PNF group; n=10), and combined treatment of chiropractic therapy and PNF group (C+P group; n=10). Subjects in three groups went through in each program for 25 min/session, three times/wk for ten weeks. LLA, PD, height, weight, and BMI were measured and compared between groups and between pre- and post-test utilizing two-way ANOVA with repeated measures. All variables regarding spinal alignment and physique increased significantly in all three groups. The changes in C+P group were more than other two groups. It was concluded that all three treatments would be an effective intervention for the functional recovery of the spinal alignment and the physique in forward head posture patients. Especially, concurrent treatment of the two types would be more beneficial.
