Automatic design, planning and drawing of scaffolding system for constructions
Hara, Takashi,Shimomura, Katsukiyo,Hamano, Keita,Miyake, Shoko Techno-Press 2019 Advances in computational design Vol.4 No.2
Temporary scaffold systems in the construction site play an important role for ensuring the safety of the workers and for constructing the stable structures. To assemble the scaffold, the pipe scaffolding system, the wedge binding scaffolding system and the particular materials have been utilized. To design the material arrangement of a scaffold, firstly the configuration was determined considering the construction geometry. Then, the strength of the scaffold was confirmed and the quantity of the material was accounted. In this paper, the design method of the temporary scaffold was proposed for intending the semi-automatic procedure. In the proposed design method, the geometric design and the safety requirement were specified by the safety standard and the design flow was followed by the designer's knowledge. The size and the quantities of the materials were calculated by referring to the relation between the scaffold and the constructing structure. In the calculating procedure, three dimensional positions of each scaffold materials were calculated and recorded simultaneously. Then, three dimensional scaffold structural was drawn semi-automatically on the CAD software by using the obtained material sizes, positions and directions. The proposed design method provides us the precise quantities of scaffold materials and enables us to reduce the design effort and the cost estimation processes. In addition, the obtained results can be applied to BIM software after converting to IFC format.

The characteristic muonic X-ray measuring system for low pressure gas sample was constructed to investigate the initial process of muonic atom formation. Low background characteristic muonic X-ray spectra were obtained for neon (1.0 bar) and nitrogen mono-oxide samples (0.99 bar) by muon irradiation with 19 MeV/c. The deviation of characteristic muonic X-ray intensity patterns both for muonic nitrogen and oxygen atoms in nitrogen mono-oxide sample between our low pressure experiment and the previous high pressure experiment was found. Muon capture probability was also determined and compared with the previous work and empirical estimations.

In the bipolar basidiomycete Pholiota nameko, a pair of homeodomain protein genes located at the A mating-type locus regulates mating compatibility. In the present study, we used a DNA-mediated transformation system in P. nameko to investigate the homeodomain proteins that control the clamp formation. When a single homeodomain protein gene (A3- hox1 or A3-hox2) from the A3 monokaryon strain was introduced into the A4 monokaryon strain, the transformants produced many pseudo-clamps but very few clamps. When two homeodomain protein genes (A3-hox1 and A3-hox2) were transformed either separately or together into the A4 monokaryon, the ratio of clamps to the clamp-like cells in the transformants was significantly increased to approximately 50%. We, therefore, concluded that the gene dosage of homeodomain protein genes is important for clamp formation. When the sip promoter was connected to the coding region of A3-hox1 and A3-hox2 and the fused fragments were introduced into NGW19-6 (A4), the transformants achieved more than 85% clamp formation and exhibited two nuclei per cell, similar to the dikaryon (NGW12 -163 × NGW19-6). The results of real-time RT-PCR confirmed that sip promoter activity is greater than that of the native promoter of homeodomain protein genes in P. nameko. So, we concluded that nearly 100% clamp formation requires high expression levels of homeodomain protein genes and that altered expression of the A mating-type genes alone is sufficient to drive true clamp formation.

We report the first case demonstrating an association between Kawasaki disease (KD) and erythema nodosum (EN). A 3-year-oldgirl presented with EN as an initial manifestation of KD. At the initial visit, she showed high fever of 40°C, injection of the oropharynx,cervical lymphadenopathy, and red-purple cutaneous nodules, particularly on the lower limbs. She complained of severepain in the neck and cutaneous lesions. Initially, the development of EN was attributed to Salmonella spp infection, which wasdetected in stool culture. However, the patient did not respond to high-dose ampicillin/sulbactam to which the Salmonella spp issensitive. Echocardiography performed as screening for fever of unknown origin revealed medium-sized aneurysms of the leftanterior descending artery. EN masked the diagnosis of KD, and the patient developed a coronary artery lesion. KD should beconsidered in the differential diagnosis of refractory EN in pediatric patients.
