In this paper, a simulation model for scope and filter parameters in CMIS/CMIP, OSI management protocol, has been discussed and the suitable scope type was represented by analyzing optimal polling time in network management system, queue size and response time. Scope and filter parameters in MGet, M-Set, M-Action, and =M-Delete services provide a scheme to select some managed objects, and the results are largely varied according to a scope type requested and the outcome of filtering. It has been simulated each scope type and all scope type mixed in a network by varying the offered load and a polling time. On the same time, the response time, queue size of the managing system and a delay time have been measured. As a results, the suitable scope type and polling time enhancing the network performance on the OSI network management is proposed.

The Integrated Flood Management (IFM) concept intends to obtain the maximum of benefits from the use of floodplains and the minimum of losses from flooding which seems to be the ideal outcome of flood management. For this, different strategies are recommended in order to reach this objective. The implementation of this concept leads to a resilience approach for the adaptive management of floods and is currently on its way to be better understood and integrated as part of the water resources management. There exist a fair amount of strategies to adapt to flooding that have been recommended or already implemented either as planned or autonomous ways of adaptation but their effectivity depends on the specific case where they are applied. This is why this paper looks to give a better overview of the different recommended or implemented strategies by analyzing them regarding their inherent advantages and disadvantages.

Mega-shock means a sporadic event such as the earning shock, which occurred by sudden market changes, and it can cause serious problems of profit loss of international construction projects. Therefore, the early response and prevention by analyzing and predicting the Mega-shock is critical for successful project delivery. This research is preliminary study to develop a prediction model that supports market condition analysis and Mega-shock forecasting. To avoid disadvantages of classic statistical approaches that assume the market factors are linear and independent and thus have limitations to explain complex interrelationship among a range of international market factors, the research team explored the Fractal Theory that can explain self-similarity and recursiveness of construction market changes. The research first found out correlation of the major market factors by statistically analyzing time-series data. The research then conducted a base of the Fractal analysis to distinguish features of fractal from data. The outcome will have potential to contribute to building up a foundation of the early shock warning system for the strategic international project management.

Blunt intrathoracic tracheal injuries are rare, even among blunt chest trauma patients. An early diagnosis based on a high index of suspicion allows for timely surgical management of potentially fatal airway trauma, thereby improving overall outcomes. Diagnosing these injuries can be difficult due to their nonspecific clinical features and the occasional difficulty in radiologic diagnosis. If a patient exhibits respiratory compromise with difficult ventilation and poor lung expansion, despite the insertion and management of an intercostal drain following high-energy blunt trauma, there should be a heightened suspicion of potential airway trauma. The aim of primary repair is to restore airway integrity and to minimize the loss of pulmonary parenchyma function. This case report discusses the rare clinical presentation of a patient with blunt trauma to the intrathoracic airway, the surgical management thereof, and his overall outcome. Although blunt traumatic injuries of the trachea are extremely rare and often fatal, early surgical intervention can potentially reduce the risk of mortality.

Background and Objectives： Larynx granuloma is a exophytic inflammatory mass and may result from gastroesophageal reflux disease and a traumatic or prolonged endotracheal intubation. There has been a controversy in the treatment of larynx granuloma. Our aim of study is to know the results of the conservative management and surgery for larynx granuloma. Materials and Methods : We have reviewed and analyzed medical records of 71 Patients who were diagnosed and treated as larynx granuloma in Asan medical center from 1989 to 2000 retrospectively. And questionnaires on present patient's status were answered via telephone. Results : Forty four cases were treated by conservative management and 29 cases were treated by surgery. The total Percentages of improvement after treatment were 85.7 o/o after conservative management and 75.9% after surgery. In intubation granuloma percentages of improvement were 86.4% after conservative management and 73% after surgery. In contact granuloma percentages of improvement were 85% after conservative management and 78.5% after surgery. Conclusion : Resolution and treatment periods are longer in contact granuloma compared to intubation granuloma in the groups of conservative management. (P＜0.05) There is no significant difference of their outcome between conservative management and surgery. (P＞0.05) Although this study is retrospective, conservative management is the first treatment in the management of larynx granuloma.

This study empirically analyzed the effects of the Top Management Team (TMT) on organizational performance. We verified whether the age heterogeneity, job heterogeneity (core career, core function and major), and process (communication and integration) of the TMT affect organizational performance (management performance and healthcare service quality evaluation level). We collected data about 473 members of the 2006 TMT in 81 medical institutions. We also utilized statistics of organizational performance from the Ministry for Health, Welfare and Family Affairs and the Korean Institute of Hospital Management. Results of the study showed that the age heterogeneity of TMT exerted a negative effect on the healthcare service quality evaluation level, while the process exerted a positive effect. However, the age heterogeneity, job heterogeneity, and process had no influence on management performance. We discussed the implications of such outcome of the investigation in comparison with the former studies on TMT and organizational performance, and presented its restrictions and future plans.

Purpose: The study compared the hypertension care efficacy of a case management intervention program for registered clients. Methods: The nonequivalent control group pretest-posttest design involved 53 registered hypertensive patients of a customized visiting health care service in S-city(n=28 experimental group, n=25 control group). Data collection and case management intervention were carried out from April to July, 2009. The experimental group had six home visits and two phone calls, and the control group had two home visits during the 8-week period. Outcome variables for test hypotheses were changes in physiologic index (blood pressure and total cholesterol) and degree of self-management performance and confidence. Results: Repeated measure ANOVA and t-test of means revealed significant differences before and after program for systolic and diastolic blood pressure and self-management performance and confidence, but no significant difference concerning total cholesterol. Conclusion: A case management program can have positive effects on blood pressure control and self management. However, research is needed to create a more effective case management for vulnerable patient populations.

The purpose of this study is to evaluate on the fitting with human resource practice and strategic on 6 public hospital in the point of resource based view. At the result of this study, public strategy is not much fitted into HRM(human resource management) system, but it shows positive result of the fitting with efficiency strategy and HRM system. These results were associated with the integration of G Medical Center. Generally 6 public hospitals of the HRM system and the strategy had not been linked. They also did not achieve a great outcome. We suggest that the manager in charge of each hospital make strategies of the hospital, and then evaluates about fitting with HRM system. We hope, hereafter, it applied the analysis methods that evaluates it with financing result and individual non-financial result all together.
