  • This paper presents an analytical study aimed at evaluating the seismic performance of steel moment resisting frames (MRFs) retrofitted with different approaches. For this, 3, 6 and 12 storey MRFs having four equal bays of 5 m were selected as the case study models. The models were designed with lateral stiffness insufficient to satisfy code drift and hinge limitations in zones with high seismic hazard. Three different retrofit strategies including traditional diagonal bracing system and energy dissipation devices such as buckling restrained braces and viscoelastic dampers were used for seismic upgrading of the existing structures. In the nonlinear time history analysis, a set of ground motions representative of the design earthquake with 10% exceedance probability in fifty years was taken into consideration. Considering the local and global deformations, the results in terms of inter-storey drift index, global damage index, plastic hinge formations, base shear demand and roof drift time history were compared. It was observed that both buckling-restrained braces and viscoelastic dampers allowed for an efficient reduction in the demands of the upgraded frames as compared to traditional braces.

  • A 4-year-old gelding Thoroughbred racehorse, which had been undergoing antibiotic therapy at a local veterinary clinic, was referred to the KRA veterinary center with a 20-day history of continuous right nasal discharge. Patient's history, endoscopic examination, and radiographic examination revealed primary maxillary sinusitis. Under sedation, surgical intervention was performed to collect samples and remove the accumulated mucopurulent exudate in the sinus. Swab samples were collected from the sinus during surgery for cytology and antimicrobial susceptibility testing. Only one type of bacteria was cultured, and molecular analyses of 16S ribosomal RNA gene sequences identified it as Staphylococcus aureus (S. aureus). The isolate was resistant to multiple antibiotics, which are frequently used in equine practice. Trimethoprim-sulfamethoxazole was chosen based on antibiotic susceptibility test, trephination, and sinus lavage using saline were applied to treat bacterial sinusitis. The clinical signs improved after 1 month and the patient resumed training. This report describes S. aureus isolated from bacterial maxillary sinusitis in a horse and its antibiotic susceptibility.

  • In this study, as part of the subway braking system, the structural analysis was performed with the fatigue analysis by comparing subway brake disc and wheel-type brake. When structural analysis was performed, it was possible to verify that the wheel-type brake were higher than the brake discs in case of total deformation. As the same loading conditions were given to the subway brake disc and wheel-type brake, wheel-type brakes was shown to have more deformation than brake disk but lower damage than the subway brake disc. Comparing with each fatigue loading condition, the maximum fatigue life for 'Sample history' is found to be about 60 times longer than for 'SAE bracket history'.

  • This essay reconsiders the subject of Romantic self-consciousness in a post-de Manian perspective. Self-consciousness is an attribute of Romantic lyricism whereby the poetic speaker I remains conscious of how (s)he feels or lives here and now. This self-reflective feature of Romantic poetry has been controversially interpreted either as self-centered solipsism or as self-expressive objectivism. The question is stirring more disputes among Romantic critics after the advent of New Historicism and Feminism. These two historicistic approaches reprove Romantic poetry for a lack of the sense of history and ascribes it to Romantic self-consciousness. They argue that Romantic poets in general displace historical materiality into an object of internal consciousness, so negating absurd social realities "merely to gain their own immortal soul." This essay targets to overcome this negative stance on Romantic self-consciousness with a "subversive" return to Paul de Man's criticism of Romantic internality.

Urban Impermanence on the Southern Malay Peninsula: The Case of Batu Sawar Johor (1587-c.1615)

  • This article examines the urban example of Batu Sawar which served as the capital of the Johor kingdom between 1587 and circa 1615. Around the middle of the eighteenth-century European reference works continued to describe Batu Sawar as the capital of Johor, even though the city had long ceased to serve as a trading center, let alone as Johor's capital, and probably no longer existed. Such observations raise the question of urban impermanence-the transience of sizeable settlements with reference to the Malay Archipelago. Two overarching questions form the backbone of the investigation: First, why did Batu Sawar rise as a regional trading center, and second, what are the reasons that contributed to its decline? Batu Sawar's fate was sealed by a combination of factors that included poor defenses, multiple external shocks, destruction by fire, court politics and rivalry between the early colonial powers.

  • Lidocaine is the most commonly used local anesthetic (LA) agent in various dental as well as oral and maxillofacial procedures. Although rare, adverse effects and allergic reactions to lidocaine have been reported. In patients with suspected allergy to LA or a history of such reaction, careful history-taking and allergy testing should be performed to choose an alternative LA agent to avoid any adverse effects. Here, we present two cases of delayed hypersensitivity reaction to lidocaine, wherein the patients presented with erythema, edema, and itching. Intradermal testing confirmed allergic reaction to lidocaine, and the patients underwent successful dental treatment using an alternative LA agent. This report highlights the importance of allergy testing prior to LA use considering the serious consequences of allergy to these agents and describes the management of such patients using an alternative LA agent.

  • Jangchungdan is located at the skirt of Namsan near Namsomundongcheon, so the buildings are arranged with many podiums. The steps for people to go up and down such podiums are placed around the buildings. The Western-style constructional methods and materials introduced by the opening of ports were used for a variety of Jangchungdan buildings with differentiated levels of podiums, for Jangchungdan memorial ceremonies, and other building materials were also installed along with the changes in clothes and lifestyles. Although Dansa was constructed in the Chinese style, it reflected the shrine plane used in Joseon Dynasty, which in turn is thought to reflect Gubonsincham, the basic concept of Gwangmu Reform, as in the case of Jangchungdan memorial ceremonies.

  • Compulsive behavior is a sequence of movements usually derived from normal maintenance behaviors that are performed out of context in a repetitive, exaggerated, ritualistic, and sustained manner. In general, the treatment plan includes environmental management, behavior modifications, and psychotropic medications, however, the prognosis is varied. In this case report, a 9-year-old neutered male miniature poodle presented with a lifelong history of tail chasing and mutilation. Based on the behavioral history, observations, and physical examination, compulsive disorder was diagnosed. The dog's compulsive tail chasing behavior improved only with a combination of psychotropic medications, including fluoxetine, trazodone, and gabapentin.

  • Evaluation of construction claims history can provide insights to improvement opportunities in a capital project portfolio. This study analyzed construction litigation claims extracted from the U.S. Court of Federal Claims (COFC) history involving the U.S. Naval Facilities Engineering Command (NAVFAC) from 1995-2004. Twenty-four total cases were examined over this period. Both "primary" causes and "root" causes were identified and compared to 666 litigation cases reviewed by the Armed Services Board of Contract Appeals (ASBCA). Based on the analysis, strategies for resolving future disputes are recommend using a 'hybrid' process prior to litigation.

  • Madelung's disease (MD) is a rare disease characterized by diffuse, nonencapsulated, multiple fat masses in different areas of the body. In this case report, we present a case of MD in Asia and its management. A 66-year-old man with a history of hypertension presented with massive growth of soft tissue around the neck, breasts, upper back, and lower abdomen. Preoperative magnetic resonance imaging revealed remarkably hypertrophic fat tissue around the neck and anterior chest was wall, which consistent with the diagnosis of MD. Multiple linear incisions were made on the neck and 763, 186, 635 g of posterior, right, and left fat tissues were excised, respectively. A single wide, transverse incision was done to excise 1,072 g of fat from the upper back. Masses of both breasts were excised, preserving the inferior pedicle, weighing 1,086 (right) and 1,164 g (left). The recovery was optimal and the patient was discharged without complications. In this case, we excised the adipose masses as much as possible and improved contour and symmetry. However, the fat infiltrations in the patient were diffusely distributed, making total fat excision difficult. This rare case report may help in managing patients with MD.
