Abstract. Spherical silicon (Si) photovoltaic solar cell systems combined with an electric power inverter using silicon carbide (SiC) field-effect transistor (FET) were constructed and characterized, which were compared with an ordinary Sibased converter. The SiC-FET devices were introduced in the direct current-alternating current (DC-AC) converter, which was connected with the solar panels. The spherical Si solar cells were used as the power sources, and the spherical Si panels are lighter and more flexible compared with the ordinary flat Si solar panels. Conversion efficiencies of the spherical Si solar cells were improved by using the SiC-FET.
A 50-year-old tetanic womanwith hypomagnesemiais described. She had partial resection of the stomach and thejejunum at the age of20 years. Lack of parathyroid hormone (PTH) function was indicated by hypocalcemia, hyperphosphatemia and high tubular reabsorption of phosphate. However, both plasma concentration of PTHand nephrogenous CAMP were normal. Administration of magnesiumsulfate completely normalized serum phosphate and tubular transport of phosphate with only a modest increase in nephrogenous CAMP. The present findings suggest that phosphaturic action of PTHis impaired in magnesiumdeficiency and that steps distal to CAMP production may be responsible for the renal refractoriness to the hormonal action.

Nowadays, in many enterprises, for the purpose of the efficiency improvement and the automation of the business, the "workflow management system of the business process" is coming into wide use. However, individual workjow management system is introduced into each organization. So the workjow system is effective as a business support inside of a single organization, but it is dificult to apply this management system to coordinate business among more than two organizations.In this paper, we propose Interworkjow system which coordinates each workjow system among multiple organizations. Interworkjow system consists of the following three sub-systems and has friendly user interjace. We report on the fact that we have constructed an actual Interworkflow system that coordinates multiple workflow systems and confirm that it functioned effectively.1. Three-dimensional graphical modeling tool in order to define lnterworkjow.
