Effects of near-fault loading and lateral bracing on the behavior of RBS moment connections
Qi-Song “Kent” Yu,Chia-Ming Uang 국제구조공학회 2001 Steel and Composite Structures, An International J Vol.1 No.1
An experimental study was conducted to evaluate the effects of loading sequence and lateral bracing on the behavior of reduced beam section (RBS) steel moment frame connections. Four full-scale moment connections were cyclically tested-two with a standard loading history and the other two with a near-fault loading history. All specimens reached at least 0.03 radian of plastic rotation without brittle fracture of the beam flange groove welds. Two specimens tested with the nearfault loading protocol reached at least 0.05 radian of plastic rotation, and both experienced smaller buckling amplitudes at comparable drift levels. Energy dissipation capacities were insensitive to the types of loading protocol used. Adding a lateral bracing near the RBS region produced a higher plastic rotation; the strength degradation and buckling amplitude were reduced. A non-linear finite element analysis of a one-and-a-half-bay beam-column subassembly was also conducted to study the system restraint effect. The study showed that the axial restraint of the beam could significantly reduce the strength degradation and buckling amplitude at higher deformation levels.
The Outlier Alliance: US-Japan Security Ties in Comparative Perspective
( Kent E Calder ) 한국국방연구원 2003 The Korean Journal of Defense Analysis Vol.15 No.2
This paper examines the US-Japan bilateral security alliance in comparative perspective in an effort to identify distinctive structural features and evolutionary trends. The policy objective is to understand the prospective cohesion of the alliance relationship between these two political/economic powers, which between them generate over 46 percent of global GDP and account for nearly 50 percent of the world`s military expenditure. A comparison is made with the contemporary US-Japan alliance and other security alliances in the Pacific and the rest of the industrialized world. Comparisons are made within three basic dimensions: (A) Patterns of security cooperation; (B) Political-economic linkages within bilateral alliance-related relationships; and (C) Asymmetries in security and economic spheres. The final section of the paper asks: "Why?"-after identifying the underlying causal dynamics that have forged the current US-Japan alliance, it enquires what these imply for that partnership`s future operation. It concludes that future consolidation is likely, with broad geo-political consequences that urgently need further exploration.
Fatty Acid Modulation of Atherosclerosis by Peroxisome Proliferator - Activated Receptors
Kent L. Erickson,Neil E. Hubbard,Lynette M. Meinecke 한국식품영양과학회 2002 Preventive Nutrition and Food Science Vol.7 No.4
While atherosclerosis is a major killer, there is now concern that mortality from the disease will increase due to the rising incidence of type II diabetes. Because diet can potentially influence both diseases, it is important to elucidate the role of diet in the progression of atherosclerosis. In addition, the mechanisms involved in dietaryrelated alterations of the disease need to be defined to guide public health recommendations to reduce atherosclerosis incidence and limiting unwanted side effects. Since diet is thought to play a role in atherosclerosis even without added complications due to type II diabetes, reducing the incidence of that metabolic disease will not be enough. While evidence is increasing that high intake of carbohydrate can lead to type II diabetes and atherosclerosis, the preponderance of existing evidence indicates that intake of specific fats as a major dietary causal factor. It has recently been hypothesized that a dietary fat link to atherosclerosis may depend partly on the activity of a transcriptional regulator, the peroxisome proliferator activated receptors (PPAR). Thusfar, PPAR α, β/δ andγ, have been shown to play a major role in metabolism, inflammation, and cancer. Furthermore, PPAR may regulate specific processes associated with atherosclerosis such as triglyceride and low density lipoprotein (LDL) metabolism; the reverse cholesterol transport pathway; lipid accumulation within plaques; the local inflammatory response and plaque stability. Synthetic ligands for PPAR have been developed; however, natural ligands include specific fatty acids and their metabolites. Though the role of PPAR in atherosclerosis has been reported with respect to synthetic ligands, additional studies need to be done with established and possible natural ligands. In this review, we will focus on the relation of dietary fat to PPAR alteration of atherosclerosis.
Quiet Crisis Beneath the Waves: Fiber-Optic Cables, Internet Revolution, and International Order
Kent Calder,백민정 한국국방연구원 2024 The Korean Journal of Defense Analysis Vol.36 No.1
Undersea cables have been a strategic resource for major nation-states over the years. The first international undersea cable was laid between Europe and North America in 1858, just over a decade after the first telegraph message was sent in 1844. With the advent of fiber-optic technology in the late 1980s, undersea cables took on a drastically enhanced functional role in the global political economy. Fiber-optic communications led to an explosive expansion of Internet connectivity, which inevitably flowed beneath the seas due to its cost-effectiveness and freedom from regulation. Despite its critical and rapidly increasing global importance, the undersea cable network has faced formidable challenges in its evolution over the past three decades. Most importantly, there needs to be a clearly defined, practical legal framework that regulates this profitable, high-growth, and strategically important sector. This lack of regulation has proved both a blessing and a curse for Big Tech firms that are the principal owners of undersea cables, such as Google, Facebook, Amazon, and Microsoft. A second major challenge has been the rise of mercantilist challengers to Big Tech preeminence, especially from state-sponsored Chinese enterprises. The Chinese share of international subsea fiber-optic cable has doubled over the past decade. China has also broadened cable coverage systematically to developing nations of Africa, South Asia, and Latin America, with broader geopolitical implications. Concrete suggestions on how to better protect sensitive data mainly when they are physically located in international waters inside undersea cables, are explored in this article.
Why linguists like the colloquial marker ‘like’
Kent Lee 한국언어과학회 2020 한국언어과학회 학술대회 Vol.2020 No.10
The colloquial discourse particle ‘like’ has attracted some attention in the pragmatics and semantics literature. This particle is of interest to linguists because of its varied usage and properties. Past analyses have treated it as a hedge, approximator, and focus particle. Good empirical evidence and analysis exists for its hedging functions, but the proposals related to focus have not been so well developed. If it indeed has focus marking properties, it is not clear what kind of focus is involved, or how that can be reconciled with its hedging functions. For this presentation, two small sets of conversational data are examined, showing that it shows both hedging and focusing functions. This talk will sketch out a possible hypothesis that could explain its focusing functions, and how that might be reconcilable with its hedging functions. Such a hypothesis indicates that it has interesting pragmatic properties that deserve further research.
