Study on Moth Diversity in islands and land borders, in the southwest area of Korean Peninsula

AbstractIn order to investigate moth diversity in the bordering islands and inland in the southwest area of Korean Peninsula, a total of 1,127 individuals of 270 species from 214 genera, 16 families, 1 order were collected from four inland sites and four island sites near Mokpo, at the southern end of the Korean Peninsula from April to October of 2009. According to the analysis of the collected moths, Noctuidae with its 102 species were the most frequently collected order and followed by Geometridae and Pyralidae. Among the 5 regions studied every month (Yangeulsan (Mt.), Oedaldo, Yudalsan (Mt.), Ibamsan (Mt.), Seungdalsan (Mt.)), Mt. Seungdalsan showed the highest species diversity with 129 species from 452 moths collected, followed by decreasing order of Yangeulsan at 70 species from 139 moths, Ibamsan at 59 species from 116 moths, Oedaldo at 58 species from 133 moths and Yudalsan of 48 species from 125 moths. In the three regions in which samples were taken once, Dalido showed the highest figure at 49 species from 98 moths collected, followed by Gohado at 23 species from 37 moths and Heosado at 14 species from 27 moths

Analysis of a Long Volumetric Module Lift Using Single and Multiple Cranes

Industrialized and modular construction is a growing construction technique that can transfer a large portion of the construction process to off-site fabrication yards. This method of construction often involves the fabrication, pre-assembly, and transportation of massive and long volumetric modules. The module weight keeps increasing as the modules become more complete (with infill) to minimize the work at the site and, as higher productivity can be achieved at the fabrication shop. Thus, a volumetric module delivery gets more challenging and risky. Despite its importance, past research paid relatively insufficient attention to the problem related to the lifting of heavy modules. This can be a complex and time-consuming problem with multiple lifting for transportation-and-installation operations both in fabrication yard and jobsite, and require complex crane operations (sometimes, more than one crane) due to crane load capacity and load balance/stability. This study investigates this problem by focusing on the structural perspective of lifting such long volumetric modules through simulation studies. Various scenarios of lifting a weighty module from the top using four lifting cables attached to crane hooks (either a single crane or double crane) are simulated in SAP software. The simulations account for various factors pertaining to structural indices, e.g., bending stress and deflection, to identify a proper method of module lifting from a structural point of view. The method can identify differences in structural indices allowing identification of structural efficiency and safety levels during lifting, which further allows the selection of the number of cranes and location of lifting points

Transmural Migration of Surgical Sponge Evacuated by Defecation: Mimicking an Intraperitoneal Gossypiboma

The spontaneous defecation of the surpical retained sponge is very rare. Here, we report a case of migrating surgical sponge that was retained in the colon and it was evacuated by defecation

Clinical and Pathological Characteristics of Four Korean Patients with Limb-Girdle Muscular Dystrophy type 2B

Limb-girdle muscular dystrophy type 2B (LGMD2B), a subtype of autosomal recessive limb-girdle muscular dystrophy (ARLGMD), is characterized by a relatively late onset and slow progressive course. LGMD2B is known to be caused by the loss of the dysferlin protein at sarcolemma in muscle fibers. In this study, the clinical and pathological characteristics of Korean LGMD2B patients were investigated. Seventeen patients with ARLGMD underwent muscle biopsy and the histochemical examination was performed. For the immunocytochemistry, a set of antibodies against dystrophin, α, β, γ, δ-sarcoglycans, dysferlin, caveolin-3, and β-dystroglycan was used. Four patients (24%) showed selective loss of immunoreactivity against dysferlin at the sarcolemma on the muscle specimens. Therefore, they were classified into the LGMD2B category. The age at the onset of disease ranged from 9 yr to 33 yr, and none of the patients was wheelchair bound at the neurological examination. The serum creatine kinase (CK) was high in all the patients (4010-5310 IU/L). The pathologic examination showed mild to moderate dystrophic features. These are the first Korean LGMD2B cases with a dysferlin deficiency confirmed by immunocytochemistry. The clinical, pathological, and immunocytochemical findings of the patients with LGMD2B in this study were in accordance with those of other previous reports
