The structure should be designed to be safe to any direction of earthquake input. However, the reference axes whereby the structure is analyzed and designed against earthquake may influence the design member forces. This study is concerned with the effect of the choice of the reference axes on the seismic design member forces. The analytical results on member forces using the principal axes suggested by Wilson and the global axes generally adopted in design offices show that the values of member forces by the principal axes be about $15\%$ smaller than those by the global axes in the example structure.

This paper presents a novel method to carry out monitoring of transport infrastructure such as pavements and bridges through the analysis of vehicle accelerations. An algorithm is developed for the identification of dynamic vehicle-bridge interaction forces using the vehicle response. Moving force identification theory is applied to a vehicle model in order to identify these dynamic forces between the vehicle and the road and/or bridge. A coupled half-car vehicle-bridge interaction model is used in theoretical simulations to test the effectiveness of the approach in identifying the forces. The potential of the method to identify the global bending stiffness of the bridge and to predict the pavement roughness is presented. The method is tested for a range of bridge spans using theoretical simulations and the influences of road roughness and signal noise on the accuracy of the results are investigated.

This research report cuts across management sciences (market strategy entry mode development) and innovative technology (Electric Vehicle (EV)) alongside measures to submerge global warming. The development of a successful entry mode for the electric Vehicle into the African continent is the main objective of the study. The study focuses on an analysis of how electric car manufacturers can enter the African market in other to achieve global sustainability and social responsibility. The methodology is based on identifying the factors that affect the choice of an entry mode into international markets by multinational companies desiring to leverage their revenue through a foreign market. It also offered a quantitative approach that can support the economic and sustainability entry mode model for EVs and a qualitative approach of Porter's five forces analysis as an entry mode coaching tool for EVs. These proxies are used in quite a wide range of multivariate statistical methods (trend analysis, ratio, and probability, comparative t-test technique, auto-regression, and ordinary least square technique). The result acknowledges joint venture and setting of the plant (physical presents) as the optimal entry mode in African EV market. It requires the EV manufacturers a tire-free emission innovation technology in order to optimize the global sustainability initiative.

1990년대 초반 이후부터 한국 시장에 본격적으로 등장하기 시작한 글로벌 여성잡지는 다른 글로벌 미디어 상품과는 달리 라이선스 계약이나 조인트 벤처를 통한 국내 출판사와의 파트너십을 통해 국내에서 제작 출판되고 있다. 이러한 소유구조의 특성으로 인해 글로벌 여성잡지에서는 글로벌 요소와 지역 요소가 혼재되어 나타나고 있는데, 다양한 글로벌/지역 요소들의 이해관계가 나타나는 글로벌 여성잡지는 단순히 글로벌 미디어라고 보기보다는 다양한 지역 요소들을 반영하고 이와 관계를 맺으며 새로운 콘텐츠를 생산해내는 글로컬(glocal)화된 미디어라고 할 수 있다. 따라서 본 연구에서는 글로벌 여성잡지에 나타나는 글로벌과 지역의 역동적 상호작용의 이해를 위해 제작과정에 나타나는 글로벌/로컬 요소를 살펴보고, 이러한 요소들이 서로 어떻게 상호작용하고 있는가를 현업 종사자들과의 인터뷰를 통해 알아보고자 하였다. 연구결과, 글로벌 여성잡지의 현지화 과정은 글로벌 미디어의 일방향적 동질화 과정이 아니라 지역 현실을 반영하는 글로벌과 지역의 상호작용 과정임을 보여주었으며, 글로벌 여성잡지 종사자들은 본사의 방침을 따라 기사의 콘셉트와 형식을 유지하면서도 한국 실정에 적합한 기사를 생산하고자 노력하고 있음을 볼 수 있었다.

본 고에서 우리나라의 클러스터들이 세계에서 경쟁력 있는 혁신클러스터로 자리매김 할 수 있는 잠재경로와 클러스터의 형성을 촉진할 수 있는 정책개입의 방향에 대하여 탐색하고자 한다. 세계적인 클러스터가 되기 위해서는 클러스터의 구성원들이 끊임없이 변하는 자본주의 경제의 전환력에 대하여 집단적으로 대응하는 것이 필요하고 그 과정에서 각기 독특한 경쟁력이 창출된다는 것이 이 논문의 핵심적 주장이다. 우리나라는 급속한 경제성장 과정에서 다양한 자산들을 축적하였고 이런 자산들은 우리나라에서 세계적인 선도 클러스터를 창출하는 데 효과적으로 활용될 수 있다. 이 과정은 실리콘밸리와 같은 유일한 모델을 베끼는 것이 아니라 한국의 지역적 조건에 맞는 독자적인 모델을 창출하는 것이다. 이를 위해서 우리나라 혁신클러스터의 재창조 과정이 요구된다.

A new method for designing moment resisting concrete frames failing in a global mode is presented in this paper. Starting from the analysis of the typical collapse mechanisms of frames subjected to horizontal forces, the method is based on the application of the kinematic theorem of plastic collapse. The beam section properties are assumed to be known quantities, because they are designed to resist vertical loads. As a consequence, the unknowns of the design problem are the column sections. They are determined by means of design conditions expressing that the kinematically admissible multiplier of the horizontal forces corresponding to the global mechanism has to be the smallest among all kinematically admissible multipliers. In addition, the proposed design method includes the influence of second-order effects. In particular, second-order effects can play an important role in the seismic design and can be accounted for by means of the mechanism equilibrium curves of the analysed collapse mechanism. The practical application of the proposed methodology is herein presented with reference to the design of a multi-storey frame whose pattern of yielding is validated by means of push-over analysis.

A method that can estimate global deformation and internal forces using a limited amount of displacement data and based on the shape superposition technique and a neural network has been recently developed. However, it is difficult to directly measure sufficient displacement data owing to the limitations of conventional displacement meters and the high cost of global navigation satellite systems (GNSS). Therefore, in this study, the previously developed estimation method was extended by combining displacement, slope, and strain to improve the estimation accuracy while reducing the need for high-cost GNSS. To validate the proposed model, the global deformation and internal forces of a cable-stayed bridge were estimated using limited multi-response data. The effect of multi-response data was analyzed, and the estimation performance of the extended method was verified by comparing its results with those of previous methods using a numerical model. The comparison results reveal that the extended method has better performance when estimating global responses than previous methods.

이 논문의 목적은 1961년부터 2010년까지 한국의 경제발전 궤적을 고찰하는데 있다. 이 기간 동안 한국 경제의 고성장은 시기별로 다른 한국의 발전모델에 기인한다. 한국의 발전모델을 시기적으로 살펴보면, 1980년대 후반까지의 발전양식은'대량생산-대량수출'과'고생산성-저임금'의 결합을 통하여 구현된 수출지향형 산업화 모델에 초점을 두고 있다. 이후 1990년대 후반까지의 발전모델은'대량생산-대량수출'전략을 지속해 오면서'고생산성-고임금'의 결합에 기초하고 있으며, 2000년 이후의 발전모델은 한국의 금융위기를 극복하기 위하여'공공부문과 민각부문의 재편'및'시장화 전략과 사회 안전망의 점진적 확충'에 초점을 두고 있다. 이와 같은 발전모델은 첫째, 세계적 차원의 조절양식인 무역제도, 환율, 세계와 한국 간 산업관계, 개발도상국에 대한 차관 제도와 관계가 있으며, 둘째, 국가적 차원에서의 조절양식인 국가, 자본, 노동 간에 이루어지는 3각 관계의 변화와 관계가 있다. 그러므로 세계적-국내적 차원에서 조절양식은 한국의 수출지향형 자본축적 과정을 안정화시키는 데 있어서 중요한 게임의 규칙이 된다.

"The world is flat" as the popular author Thomas L. Friedman declares in his best belling book about the progress of business globalization in the $21^{st}$ century [3]. Construction projects and related businesses have been global since the 1800's, but it has never seen such rapid transformation in both scope and depth as in the past decade. Construction projects today often bring together international design talents, construction management firms, local and international labor forces, and global suppliers. On a visit to Dubai in the United Arab Emirates on the Persian Gulf, a person will experience the complexity of globalization of modern construction projects- with Arab owners, European engineering and design companies, American construction management teams, Korean general contractors, Jordanian subcontractors, and labor forces from Thailand, Indonesia, Turkey, and Sri Lanka. A count of material suppliers reveals over 60 countries involved, covering all continents. Indeed construction projects are getting more and more complex and competitive, as is the project execution. The trend toward globalization poses both challenges and opportunities to construction and engineering companies competing on a global scale. While global competition may be a threat to many companies, there are, however, many opportunities for synergistic collaborations that can create win-win scenarios for construction business, research, and education. This paper presents some of the opportunities between the U.S. and Asia in business integration, research collaboration on technologies, and educational development, which may mutually benefit countries on either side of the Pacific.
