These huge amounts for executive compensation are being questioned in comparison to the dividends received by stockholders. Four companies are analyzed： Citigroup, Starbucks, General Electric （GE）, and Kraft Foods. Present issues faced by Citigroup show that the company＇s provision in their executive compensation is not acceptable, On the other hand, Starbucks, GE, and Kraft Foods are the companies that follow legal rules provided by the Securities and Exchange Commission （SEC） in providing compensations to executives. Thus, they are good exemplars to other companies.展开更多

Methods: 30 patients with VEGF-positive bronchogenic adenocarcinomas (diameter ≤ 4 cm) underwent multi-location dynamic contrast material-enhanced (nonionic contrast material was administrated via the antecubital vein at a rate of 4 mL/sec by using an autoinjector) serial CT. The quantifiable parameters (Perfusion, peak height, ratio of peak height of the bronchogenic adenocarcinoma to that of the aorta and mean transit time) of blood flow pattern derived with dynamic CT in solitary bronchogenic adenocarcinoma were compared with microvessel densities (MVDs) and VEGF expression by immunohistochemistry. Results: Peak height of VEGF-positive bronchogenic adenocarcinoma was 36.06 HU ± 13.57 HU, bronchogenic adenocarcinoma-to-aorta ratio 14.25% ± 4.92, and perfusion value 29.66 ± 5.60 mL/min/100 g , mean transit time 14.86 s ± 5.84 s, and MVD 70.15 ± 20.03. Each of peak height, ratio of peak height of the bronchogenic adenocarcinoma to that of the aorta and perfusion correlated positively with MVD (r = 0.781, P < 0.0001; r = 0.688, P < 0.0001; r = 0.716, P < 0.0001; respectively). No significant correlation was found between mean transit time and MVD (r = 0.260, P = 0.200 > 0.05). Conclusion: Perfusion, peak height and ratio of peak height of the bronchogenic adenocarcinoma to that of the aorta reflect MVD in VEGF-positive bronchogenic adenocarcinoma. Perfusion, peak height and ratio of peak height of the bronchogenic adenocarcinoma to that of the aorta derived with dynamic CT might be index for VEGF-related tumor angiogenesis in bronchogenic adenocarcinoma.展开更多

When analyzing the development process of Polish cities, an obvious conclusion emerges about the lack of complex studies and researches of the environment concerning the issue of acoustic climate. The procedures of development of local land use plan involve merely a general diagnosis of an environment excluding measured values of pollution, including noise levels. The main aim of this article is to introduce the issue of the influence that acoustic climate has on the urban space planning with the application of SNM （strategic noise mapping）. The map enables holistic assessment of the degree to which urban areas are exposed to noise, determines its sources and forecasts variations of its levels. Preliminary research results confirmed the necessity of including noise level influence in the procedures related to urban space planning especially concerning its forecasted levels resulting from estimates of local land use plans. Applying SNM in verification of conceptual space arrangements in terms of protection against noise in the preparation of LLUP as well as their further application in the plan is a considerable advantage.展开更多

However, warehousing and transportation of CBM become one of the core factors that restrain its exploitation and utilization at present, due to the space-time character of natural deposit and modem utilization of CBM. In this paper, according to the character of CBM and the expanding trend of its utilization, the necessity of constructing the CBM＇s warehousing and transportation management system demonstrated. Index system that influence CBM＇s warehousing and transportation is established. And CBM＇s warehousing and transportation model is established by Voronoi diagram. In light of above research, CBM＇s warehousing and transportation management system based on Geography Information System （GIS） is designed, Using this system, CBM＇s warehousing and allocation center in one mining area is optimized. Research shows that to reinforce CBM＇s warehousing and transportation management is one of the key factors for coordinating the development of its development and utilization, thereby ensuring its sustainable development and utilization.展开更多
