Aiming at the problem of difficult data collection of single disease in hospital, the authors designed a solution to realize the fine management of single-disease data based on data center. The hospital optimized the data quality through overall management, unified the data collection source based on the data center, built a single-disease intelligent collection platform to complete the data collection, and calibrated the data to ensure its accuracy, so as to form a single-disease index management process and realize high-quality data collection. The average actual backfill rate was as high as 95.7%. On this basis, the hospital optimized the single-disease reporting and quality control management mode to further promote the fine management of medical quality.

Evaluation of the Heat and Energy Performance of a Datacenter Using a New Efficiency Index: Energy Usage Effectiveness Design - EUED

Abstract Data Centers are growing steadily worldwide, and they are expected to continue growing up to 53% in 2020. Energy efficiency, in high power consumption, is a key venue. There are methodologies to measure this efficiency, one example is using the PUE (Power Usage Effectiveness) index. In this paper is proposed a new index for measuring efficiency at the design stage, the EUED (Energy Usage Effectiveness Design). This index allows to evaluate systems using "free cooling" and adiabatic system. A comparison is performed considering the equipment in the worst situation. The thermodynamics parameter enthalpy is used to calculate the results. This new methodology allows to determine differences between the cities of São Paulo and Curitiba (1.21%) and between Rio de Janeiro and Curitiba (10.61%). The values for the EUED index were 1.245 kW/kW for Curitiba, 1.260 kW/kW for São Paulo and 1.377 kW/kW for Rio de Janeiro, respectively, reaching a difference of 16.86% for Curitiba, 16.19% for São Paulo and 10.31% for Rio de Janeiro in relation to PUE COA (Power Usage Effectiveness Constant Outdoor Air). The advantage of the EUED is that it works with the 8,760 hours in the design phase, using psychometric elements to determine when to use free cooling and evaporative system, and more importantly varying the COP according to environmental characteristics.

Study on four polymorphs of bifendate based on X-ray crystallography

Bifendate, a synthetic anti-hepatitis drug, exhibits polycrystalline mode phenomena with 2 polymorphs reported (forms A and B). Single crystals of the known crystalline form B and 3 new crystallosolvates involving bifendate solvated with tetrahydrofuran (C), dioxane (D), and pyridine (E) in a stoichiometric ratio of 1:1 were obtained and characterized by X-ray crystallography, thermal analysis, and Fourier transform infrared (FT-IR) spectroscopy. The differences in molecular conformation, intermolecular interaction and crystal packing arrangement for the four polymorphs were determined and the basis for the polymorphisms was investigated. The rotation of single bonds resulted in different orientations for the biphenyl, methyl ester and methoxyl groups. All guest solvent molecules interacted with the host molecule via an interesting intercalative mode along the [1 0 0] direction in the channel formed by the host molecules through weak aromatic stacking interactions or non-classical hydrogen bonds, of which the volume and planarity played an important role in the intercalation of the host with the guest. The incorporation of solvent-augmented rotation of the C-C bond of the biphenyl group had a striking effect on the host molecular conformation and contributed to the formation of bifendate polymorphs. Moreover, the simulated powder X-ray diffraction (PXRD) patterns for each form were calculated on the basis of the single-crystal data and proved to be unique. The single-crystal structures of the four crystalline forms are reported in this paper.

<b>4．New Paradigm for Post-marketing Surveillance in Japan Which is Introduced New Pharmaco-epidemiology Research Design and Integrated Data Center Based Disease Registry </b> / 薬剤疫学

Using foreign clinical trial data in new drug submission, new drug can be approved with a few observations of Japanese patients. In current Japanese drug development situation, the importance of post-marketing surveillance (PMS) for Japanese patients has been increased. Rigid PMS system in Japan which has no selective options should be rescinded. In order to perform primary role of PMS which is to keep in safety and efficacy of pharmaceutical and medical devices, the Japanese PMS should change from standard form to selection of study design according to scientific consideration. The paper proposed that new pharmaco-epidemiology research design was applied to PMS and PMS were conducted by independent and integrated data center based disease registry.
