The UBV observations of the close binary system CW Cephei were made from August 198:3 to December 1984 during 25 nights using the 61cm Boller and Chivens reflector at the Sobaeksan Astronomy Observatory. The new UBV light curves were analyzed with the recent Wilson-Devinney binary model. Our photometric solution for CW Cep were well consistent with those of Clausen &. Gimenez (1991). Using our photometric solution and Popper & Hill (1991) spectroscopic one, each absolute masses and radii of components for CW Cep were derived as 13.63 M<TEX>$\bigodot$</TEX> and 5.83 R<TEX>$\bigodot$</TEX> for the primary, and 12.18 M<TEX>$\bigodot$</TEX> and 5.14 R<TEX>$\bigodot$</TEX> for the secondary, respectively.

There is a question, 'Which is beautiful, a flower or a star?'. Its answer is different from one person .to another. It is only a matter of what one is interested in. It is very difficult for most school pupils, who will have non-scientific jobs, to understand science courses taught currently in school, because each science (physics, chemistry, biology, and earth science) is independently taught from the other sciences. Therefore, their knowledge of sciences obtained during their school period does not significantly help their understanding of global environmental problems. I am proposing that several scientific stories should be prepared to connect all the related scientific phenomena in order to give those pupils ideas in understanding global environmental problems. I believe that astronomy is able to play an important role in this context.

UBV observations have been made jointly at three observatories for the recent eclipse of the long period atmospheric eclipsing binary star Zeta Aur in 1995-6. Observations covered successfully the phases before, during, and after the eclipse enable us to determine the accurate time of mid-eclipse and the duration of the totality. The hypothesis of the expansion of the K supergiant has been tested and the positive conclusion may be derived.

With an interim calibration based upon half the Key Project's galaxies, the Tully-Fisher relation, the (Dn, <TEX>$\sigma$</TEX>) relation and type II supernovae yield <TEX>$H_0$</TEX>= 73<TEX>$\pm$</TEX>10 km/sec/Mpc.

We review current theoretical understanding of the spectral properties (low and high states, transition of states, quasi-periodic oscillations etc.) of the low mass as well as supermassive black hole candidates.

For obtaining estimates of a total magnetic flux, we propose to use measurements of <TEX>${\partial}I/{\partial}{\lambda}$</TEX>. obtained by a modulation method which is formally identical to Stokes V-parameter measurements. In this case the polarization is not analyzed. It is advisable to use in measurements two parts of the spectral line wing.

It. has been discovered that. active regions commonly have numerous flare-like transient. loop brightenings. We use a magnetic reconnection theory driven by a ponderamotive force on account. of the basic properties of a transient. brightening: lifetime a few mins, total energy <TEX>$10^{25}\~10^{29}$</TEX> erg. The numerical results are consistent with the observations.

It is analysed the discrepancy about the coronal magnetic field between solar optic and solar radio using magnetic fibril concept with filling factor and fractal structure model. The magnetic field of <TEX>$\~$</TEX> 100 G considered in solar optics is mean value in a large scale, and that of <TEX>$\~$</TEX>1000 G in solar should be the value of fine structures inside 'macro' loop.

Precise masses, radii, and luminosities from eclipsing binaries and colour-magnitude diagrams for open clusters are classic tools in empirical tests of stellar evolution models. We review the accuracy and completeness required for such data to discriminate between current models and describe some recent. results with implications for convection theory.
