수 많은 기업들이 기업 성장 및 생존 전략의 일환으로 인수․합병(M&A, merger and acquisition)을 선택하고 있다. 그러나 상당수의 기업들이 본래 의도했던 시너지 효과를 창출하지 못하고 인수․합병 실패로 인해 생산성 저하, 시장 점유율 하락, 수익 감소, 유능한 직원의 이직 등 많은 부작용을 경험하고 있다. 이에 따라 인수․합병 성공 및 실패 원인을 분석하고자 하는 많은 연구가 진행되었고, 정보시스템에 대한 기업들의 의존도 증가와 더불어 인수․합병 이후 정보시스템 통합(post-M&A information systems integration)이 인수․합병 성공에 결정적인 영향을 미치는 것으로 확인되었다. 그러나 인수․합병 이후 정보시스템 통합 성공에 대한 연구가 매우 부족하며, 대부분의 선행연구가 정보시스템 조직 통합 또는 물리적인 정보시스템의 통합 등과 같이 단편적으로 이루어져 왔다. 본 연구에서는 인수․합병 이후 정보시스템 통합 성공에 영향을 미치는 요인들에 대한 포괄적인 연구를 위하여 정보시스템뿐만 아니라 전략 경영, 경제학, 재무학, 인사관리, 조직관리 분야의 선행연구를 조사하였다. 이를 기반으로 인수․합병 이후 정보시스템 통합 영향요인에 대한 통합 모델을 제시하였다. 제시된 모형에서는 영향요인들을 인수․합병 관점, 전략 관점, 조직 관점, 인사관리 관점, 정보시스템 관점으로 재 분류하고, 사례연구를 통하여 각 요인들이 정보시스템 통합 성공에 미치는 영향을 실증적으로 검증하였다. A number of companies are considering for merger and acquisition (M&A) as one of business strat-egies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&As often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies con-ducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to in-tegration of IS organizations or physical information systems. In order to conduct a comprehensive re-search on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on com-parative case studies.
The purpose of this study was to analyze the sports massage for 20-30 aged women of obesity for 10 weeks influences on their body composition, blood sugar and blood lipids disposition factors. This will contribute to improvement of women health and prevention of adult diseases, and provide one of new methods to solve obesity by discovering whether the sports massage was effective in reducing weight. For doing this, 10 women of obesity in 20-30s with body fat of more than 30% were selected and received the sports massage three times a week (120 minutes in a session) for 10 weeks . By measuring weight, fat mass, % body fat, waist hip ratio, body mass index, blood sugar, total cholesterol in blood lipids, high protein lipid cholesterol and difference in the change of Triglyceride before and after experiments, the following results were obtained. There were statistically significant differences in weight, fat mass, % body fat, waist hip ratio and body mass index after the whole body massages(p< .05). There were statistically significant differences in blood sugar (p< .05). However, there was no significant difference in the total cholesterol, high density lipid cholesterol and triglyceride.
A detailed analytic calculation of the linear density response function (ㅣDRF)of a two-dimensional electron gas (2DEG) at zero temperature is presented. The formal derivation of the `DRF of a degenerate 2DEG is given not only to extract the naive symmetry of the 2D`DRF in imaginary frequency space but also to emphasize that the two-point density corelation function (DCF) has been modified into an unphysical DCF, which does not stand alone because it can violate the Pauli principle. A rigorous integration of the modified two-point longitudinal DCF has ben performed and its explicit analytic expresion has ben used to reproduce a result identical to that obtained by Stern, which strongly supports the validity of the employed integration technique.
Within the framework of the quasi-localized charge approximation, the Lagrange’s equation of collective modes in a strongly coupled classical bilayer liquid can be generalized beyond the harmonic approximation into the nonlinear regime up to the quadratic order.
The present study is the analyses of what has been attempted and what was understood in terms of improving the regression rate and enlarging the basic understanding of internal flow dynamics. The first part is mainly intended to assess the role of helical grain configuration in the regression rate inside the hybrid rocket motor. To improve the regression rate, a combination of swirl (which is an active method) and helical grain (which is a passive method) was adopted. The second part is devoted to the internal flow dynamics of hybrid rocket combustion. A large eddy simulation was also performed with an objective of understanding the origin of isolated surface roughness patterns seen in several recent experiments. Several turbulent statistics and correlations indicate that the wall injection drastically changes the characteristics of the near-wall turbulence. Contours of instantaneous streamwise velocity in the plane close to the wall clearly show that the structural feature has been significantly altered by the application of wall injection, which is reminiscent of the isolated roughness patterns found in several experiments.
