Natural vibration period is an important parameter for high-rise building, Based on 414 high-rise buildings completed or passed over-limit approval in China, the distribution law of natural vibration periods is analyzied. In order to satisfy the design requirements, such as global stability, story drift limit and minimum shear-gravity ratio, the reference ranges of fundamental periods $T_1$ are $0.3{\sqrt{H}}{\sim}0.4{\sqrt{H}}$ when the structural heights $H{\geq}250m$, when 150 m ${\leq}$ H < 250m, $T_1=0.25{\sqrt{H}}{\sim}0.4{\sqrt{H}}$, when 100 m ${\leq}$ H < 150 m, $T_1=0.2{\sqrt{H}}{\sim}0.35{\sqrt{H}}$, when 50 m $ {\leq}$ H < 100m, $T_1=0.15{\sqrt{H}}{\sim}0.3{\sqrt{H}}$. These can provide reference data for controlling mass and rigidity of high-rise buildings.

2050년경 중국이 21세기의 글로벌 가버넌스를 바꾸게 될 전망이다. 중국의 부상은 다른 개도국들에게 중국식 발전모델을 제공할 것으로 예측된다. 중국의 '평화적 부상'전략에는 긍정적 요소와 장애적 요소가 동시에 존재한다. 중국부상의 긍정적 요인으로는 개혁개방 정책의 성공과 경제적 상호의존의 심화로 구축된 중국경제의 세계화, 공산당의 통치 이데올로기 수정과 문화 민족주의의 적절한 이용으로 달성된 중국정권의 안정성, 그리고 유교사상의 활용과 인적자본의 강화를 기반으로 한 소프트 파워의 제고를 들 수 있다. 중국의 대국부상은 동아시아에서의 강대국 지위를 회복하는 것으로 시작된다. 중국에게 동아시아는 지속적 성장을 담보하는 생존권역(lebensraum)이다. 이를 위해 지역 경제협력의 제도화에 관심을 보이고 있다. ASEAN이 추구하는 동아시아 공동체의 핵심가치는 상호존중, 공동번영과 평등주의, 조화로운 공존을 추구하는 다원주의(pluralism)인데 중국의 정책인 조화로운 세계, 평화공존과 가치관이 일치함을 알 수 있다. 이 공통된 가치를 통해서 동아시아 지역의 긴장해소를 달성할 수 있을 것이다. 경제적인 성공과 소프트 파워를 앞세운 지역패권 전략으로 과거의 영광스러운 지위를 되찾으려 할 것이다. "동아시아에 근거를 두고 세계로 나아간다"는 동아시아 전략의 성공을 기반으로 세계규칙의 조정자가 될 수 있을 것이다. 한국을 비롯한 주변국은 중국의 '평화적 부상'전략의 최대 수혜국이 될 것이다. 중국의 부상이 주변국, 특히 우리나라에 미치는 영향은 심대한데, 현재보다 상품 이동, 노동력 이동과 양국간 자본이동의 규모가 훨씬 더 커져 육상, 해상에서 국경을 마주하고 있는 우리나라와 중국은 지역무역협정 체결으로 상호의존도가 높아질 것이다.

Tower crane is of great importance in the construction of high rise buildings. A self-lifting & slewing multi-cranes platform (referred to as crane slewing platform) was developed to optimize the configuration of tower cranes, as well as solve the problems of cooperative operation conflict between multiple cranes and other construction equipment and their respective climbing and occupying of construction period. The design and test of the slewing platform was introduced. By applying the slewing platform in the construction of Chengdu Greenland Center super high rise building project, some key technologies such as the configuration of cranes, the installation, construction and lifting of the slewing platform are implemented and validated. Up to now, the slewing platform has been safely lifted up 98 times in Chengdu Greenland Center project construction, and achieved good social and economic benefits.

In this paper, the superposition principle of a heat sink temperature rise is verified based on the mathematical model of a plate-fin heat sink with two mounted heat sources. According to this, the distributed coupling thermal impedance matrix for a heat sink with multiple devices is present, and the equations for calculating the device transient junction temperatures are given. Then methods to extract the heat sink thermal impedance matrix and to measure the Epoxy Molding Compound (EMC) surface temperature of the power Metal Oxide Semiconductor Field Effect Transistor (MOSFET) instead of the junction temperature or device case temperature are proposed. The new thermal impedance model for the power converters in Switched Reluctance Motor (SRM) drivers is implemented in MATLAB/Simulink. The obtained simulation results are validated with experimental results. Compared with the Finite Element Method (FEM) thermal model and the traditional thermal impedance model, the proposed thermal model can provide a high simulation speed with a high accuracy. Finally, the temperature rise distributions of a power converter with two control strategies, the maximum junction temperature rise, the transient temperature rise characteristics, and the thermal coupling effect are discussed.

This paper addresses the zero-sum of soft power against the backdrop of the rise of China and the relative "decline" of America. It attempts to find out that whether the "decline" of America's soft power is caused by the rise of China's soft power, and whether China's rise could guarantee with certainty the growth of soft power. In light of the particularity of South Korea, that is, its economy relies on China and its security relies on the US, this paper chooses South Korea as the entry point for the study. Based on the Pew data from a South Korean opinion poll, this paper conducts bivariate correlation and binary logistic regression respectively, to explore the existence of zero-sum "competitions" between China's and America's soft power.

As one of the most important vertical transportation equipment in super high-rise buildings, the construction elevator directly affects the project period, cost, and effectiveness. The paper proposes a new construction elevator with single-guide rail and multi-cages. It can solve the problems of single construction elevator capacity shortage and efficacy decrease with height reduction, the occupancy of plan and elevation position of multiple construction elevators, and extension of total construction period by cycling operation of multi-cages on a single-guide rail. The paper focuses on the design and research of the main components of the equipment, such as the rotating guide rail mechanism, vertical bearing mast tie system, segmented electrical power supply system, group control scheduling system, and safety anti-collision system.

Buildings, energy and the environment are key issues that the building professions and energy policy makers have to address, especially in the context of sustainable development. With more tall buildings constructed in China, the impact on energy consumption and carbon emission would be great from buildings (2% increase of carbon dioxide annually between 1971 and 2004). The imperative was to investigate the building energy performance of high-rise in different climate zones and identify the key design parameters that impose significantly influence on energy performance in sustainable building design. Design implications on glazing performance, sizing of the ventilation fans, renewable energy application on high-rise building design are addressed. Combination of effective sustainable building design strategies (e.g., building envelope improvement, daylight harvesting, advanced lighting design, displacement ventilation, chilled ceiling etc.) could contribute more than 25% of the total building energy consumption compared to the international building energy code.

중국은 이렇게 말한다. '대국이 우뚝 섰다(대국굴기). 그 파장 효과는 상당하다. 중국의 부상은 특히 한국에 위기이자 기회다. 문화산업도 마찬가지다. 중국은 사회주의 대중문화를 생산하여 소비를 촉진하고, 사회의식을 관리하려 한다. 동시에 중국은 국제적으로 문화굴기를 지향한다. 디지털화, 시장화, 지구화를 추진하는 중국은 미디어, 채널, 정보생산을 계속해서 늘려 왔다. 콘텐츠 부족은 필연적이었다. 그래서 중국은 다른 나라의 미디어, 저널리즘, 대중문화, 정보기술 등을 수입하고, 투자를 해서 대중문화 시장을 만들어 가고 있다. 이 연구는 중국 문화산업이 한국 문화 시장에 진출하여 많은 변화를 일으키고 있는 현상이 예사롭지 않다고 보고 그들의 행태를 연구하였다. 중국의 문화 시장과 미디어 정책을 분석하고, 이들이 한국 문화 시장에서 어떤 행태를 보이는지 살폈다. 논의 결과 중국은 미국을 비롯한 세계 곳곳에서 문화굴기를 시작하고 있으며, 그중 한국이 중화문화패권주의의 그늘에 갇힐 수도 있다는 점이다.
