User Interface for Sensitivity Analysis on Qualitative and Quantitative Hybrid Simulation

The qualitative and quantitative hybrid simulation system was proposed for support of designing a business scenario. In using the system, a business manager must describe a qualitative and quantitative hybrid model for the simulation, and perform sensitivity analysis to decide appropriate input values. Those are complicated tasks, so that a business manager often spends time. In order to support those tasks, we propose user interfaces that consist of a model description editor and a visualization window of changes in input values and output values for sensitivity analysis. A model description editor makes it easier to describe the hybrid model by interactive editing the model represented as a graph. A visualization window expresses changes in input values as a radar chart and plots averages and variances of changed output values for comparison. As a result of questionnaires concerning the user interface, it is confirmed that our proposed interface is effective for designing a business scenario.
Effect of ammonia treatment on white birch wood
Yamashita, Daichi,Kimura, Satoshi,Wada, Masahisa,Samejima, Masahiro,Takabe, Keiji Walter de Gruyter und Co 2018 Holzforschung Vol.72 No.1
<P><B>Abstract</B></P><P>Transverse sections of white birch (<I>Betula platyphylla</I>) were treated with anhydrous ammonia at 60-140°C (ammonia treatment, AT). As a result, the crystal structure of cellulose in the AT samples changed to cellulose III<SUB>I</SUB>, and acetamide was produced. The surface area of the AT samples, the amount of sugar released upon acid hydrolysis and the lignin content were not changed. However, a small amount of lignin became acid soluble. Mäule color reaction, indicative of the presence of syringyl lignin, showed decreasing color intensities with increasing temperature of AT. The results can be easily interpreted that AT affects ester linkages and side chains of hemicelluloses and syringyl lignin. In addition, AT was carried out on 1-μm thick transverse sections and block specimens. Xylanase treatment and immunolabeling revealed that AT enhances xylan degradation, but ray cells are resistant to xylanase even after AT. On the block sample, a deposited xylan layer appeared on the inner surface of fiber cell walls. Apparently, xylan moved to the surface in contact with the fluid ammonia during AT. The vessel cell wall did not show a similar migration effect, indicating a cell wall-specific interaction with ammonia.</P>

Objective To investigate the factors affecting the postoperative swallowing dysfunction in patients who underwent oral cancer surgery. Methods Retrospective review of clinical records of 70 patients (50 males and 20 females) who underwent oral cancer surgeries from July 2007 to April 2015 were enrolled. Multiple regression analysis was performed using the Food Intake LEVEL Scale (FILS) at discharge as the objective variable and age, tumor size, resection of the tongue base, suprahyoid muscle resection, segmental mandibulectomy, neck dissection and radiation therapy as the explanatory variables in 70 patients. In addition, multiple regression analysis was performed between objective variables, which include maximum hyoid bone movement, laryngeal elevation delay time, pharyngeal constriction ratio (PCR), residue in the vallecular and pear-shaped depression (pyriform sinuses), and Penetration-Aspiration Scale score and one of the main factors representing the characteristics of each case as the explanatory variables, and age was treated as an adjustment factor in 23 patients. Results The FILS shows significant negative correlation by age and resection of the tongue base. In videofluoroscopic swallowing study, the maximum movement, PCR and residue in the vallecular are significantly correlated with factors demonstrating the characteristic for each case. Conclusion It was suggested that in elderly patients, the presence of more than half of the tongue base resection, suprahyoid muscle resection and neck dissection cause severe dysphagia after surgery.
Inhibition of lysoPAF acetyltransferase activity by flavonoids
Yanoshita, R.,Chang, H. W.,Son, K. H.,Kudo, I.,Samejima, Y. 영남대학교 약품개발연구소 1997 영남대학교 약품개발연구소 연구업적집 Vol.7 No.-
Objective and Design: Several kinds of flavonoids, widely distributed natural products of the vegetable kingdom which possess anti-inflammatory activity, were examined for inhibitory effects on the acetyl-CoA: 1-alkyl-2-lyso-sn-glycero-3-phosphocholine (lysoPAF) acetyltransferase activity. Methods: Acetyl-CoA:lysoPAF acetyltransferase activity was determined using homogenates of a rat mucosal-type mastcytoma cell line, RBL-2H3 as an enzyme source. The production of platelet-activating factor (PAF) in rat peripheral white blood cells stimulated with the calcium ionophore A23187 was studied. Results: Of the flavonoids tested, luteolin and quercetin exhibited significant inhibitory effects (IC_(50), 45㎛ and 80㎛, respectively), whereas other structurally-related flavonoids failed to affect the lysoPAF acetyltransferase activity. Luteolin did not suppress the activity of choline acetyltransferase, suggesting that the inhibition observed here was specific. Luteolin also inhibited the production of PAF in rat peripheral white blood cells. Conclusions: These results indicate that luteolin could become a leading compound for developing a novel type of anti-inflammatory, anti-allergic drugs that target lysoPAF acetyltransferase.

Pineal organs of poikilotherm vertebrates transform the environmental light information into a humoral message and a neuronal activity. The former is melatonin, and the latter is modulation of the impulse in ganglion cells. The ganglion cells are physiologically classified into luminosity (achromatic) type and chromatic one, as the neural activity is modulated in two ways. We attempted to classify the pineal ganglion cells with morphological characteristics by means of the three- dimensional reconstruction method. In the pineal ganglion cells of river lamprey, there are two different features, oval and spherical. For comparison of their projection region in the brain, the tracing investigation was also carried out. The application of the neural tracer near mesencephalic tegmentum showed that only oval-shaped ganglion cells were labeled in the pineal organ. These results suggest that the oval-shaped ganglion cell is functionally different from the spherical one.
