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.

본 논문은 전략집단 이론을 활용하여 PP 사업자의 분석에 대한 현황, 성과와 한계를 살펴보고 개선방향을 모색했다. 기존 전략집단 개념을 활용한 PP사업자 분석의 한계는 전략집단의 도출이 통계결과에 따라 PP의 채널 특징만을 반영했다. 그렇기 때문에 전략 및 전략집단의 유형을 체계적이고 정교하게 분류하기 어려웠고 일반화가 어려운 것으로 나타났다. PP의 전략 변수 선정은 기업 및 사업부 수준(분석수준), 자원 및 경쟁범위와 관련된 변수를 사용했다. 향후에는 보다 적절한 절차에 따라 변수를 객관적으로 선정하여 자의성에 대한 논란을 피해야 할 것이다. PP 사업자의 전략집단 연구의 개선방향은 크게 다섯 가지로 요약되었다. 첫째, 전략 집단 분류 변수를 요인분석하고 몇 개의 요인으로 축약하여 분류기준이 되는 핵심 변수를 선정하는 것이 필요하다. 둘째, 산업 전문가들로부터 변수를 크로스 체크하여 일반화 가능성을 향상시켜야 한다. 셋째, 대리변수를 지양하고 PP 산업 특유의 속성을 반영할 수 있으며 경영자가 인지적 차원에서 지각할 수 있는 전략집단 모델을 연역적으로 개발해야 한다. 넷째, 전략집단의 분류 기준에 이동장벽과 분리기제 개념을 도입하고, 이를 통해 전략집단간 성과 차이를 규명하는 것이 바람직하다. 다섯째, PP 전략집단의 동태적 변화를 관찰하기 위한 종단적 연구가 시도되어야 한다.

PURPOSE: PURPOSE: The purpose of this study was to analyze the effect and examine the feasibility of an intervention of ankle strategy exercise on balance of patients with hemiplegia. METHODS: The subject were randomly allocated to three groups: ankle strategy exercise (group A), balance exercise (group B) and control (group C). Group A was received the conventional physical therapy plus ankle strategy exercises for 20 minutes in one session. Group B was received the same conventional physical therapy plus balance exercises for 20 minutes in one session. Two active groups were performed in the session 3 times a week, for a total of 6 weeks. and Group C was only received the same conventional physical therapy. Balance test was assessed using center of pressure (COP) in the anteroposterior (A-P), mediolateral (M-L) direction, Berg balance scale (BBS) and Timed Up and Go Test (TUG). RESULTS: All groups showed improvements in balance parameters. In especial, the Group A was statistically significant differences in almost part evaluation items and showed more improvements in BBS and TUG parameters than Group B and Group C. and moving distance of M-L COP was more improvements than Group B. CONCLUSION: Ankle strategy exercises had more influence on balance than balance exercises and neurodevelopmental treatment.

Purpose - The structure of retailing has changed as retailers develop markets in response to business environment changes. This study aims to analyze the general situation of retailers in order to predict future global strategy using case studies of overseas expansion strategy and the Metro Group's global strategy. Research design, data, and methodology - The backgrounds to the new retail business model and retailer classification are analyzed as theoretical data. In addition, the key success point of the Metro Group's "cash and carry" strategy is analyzed as is the Metro Group's global CFAR (collaborative planning, forecasting, and replenishment) strategy. Finally, the plan for cooperation and precise forecasting under the Metro Group's supply chain management are analyzed from the promotion environment viewpoint. Related materials analyzed included the 2012 annual report, the Metro Group's web page, and a video interview with the executive in charge of global strategy and the new market development department. Some data were revised to avoid disrupting essential aspects of the case studies. Results - The important finding was that the Metro Group could be a world-class retail company with its successful global expansion strategy. The Metro Group's global strategy's primary goal is to have a leading business position in Eastern and Western Europe. The "cash and carry" strategy is highest priority in its overseas expansion strategy. Moreover, the Metro Group has standardized product planning capacity, which could be applied in various countries with different structural and cultural backgrounds. This is the main reason that the Metro Group could rapidly become successful in the Eastern Europe and Asian markets through its structural overseas expansion strategies. In addition, the Metro Group emphasizes the importance of supply chain management. Conclusions - First, retailers should create additional value through utilizing the domestic market, market power, and economies of scale to launch a global strategy to maximize benefits from diversification. Second, the political, economic, and cultural background of the target country needs to be understood to successfully implement the overseas expansion strategy. Third, the main factor of successful cooperation with a local partner is how quickly the company gains total understanding of the business resources and core competence of its partner. All organizations should focus on the achievement of goals in order to successfully operate the partnership. Fourth, retailers should improve their business, financial and organizational structure. Moreover, the work processes and company culture should also be improved to respond strongly in the competitive global market. Fifth, the essential point of a successful retail business is the control capacity of its branding and format. The retailer could avoid forecasting errors through supply chain management by perfectly distributing the actual amount of its inventory. In addition, the risks along the supply chain are effectively shared between the supply chain partners. Finally, the central tendency of the market is to gain in strength with this taking place across all parts of the business.
