The stalks of the eustigmatophyte $Pseudocharaciopsis$ $minuta$ were examined by light and scanning electron microscopy. Light microscopy revealed orange-red granules at the base of the stalk. Energy dispersive X-ray microanalysis of the bases indicated that they were mainly composed of manganese. Manganese has not been previously reported from eustigmatophytes. This study indicates that the Eustigmatophyceae needs further study into many aspects of the biology.

TiN 박막은 저온(<$500^{\circ}C$), 저압(1Torr)에서 Tetrakis(diethylamido)titanium[TDEAT, Ti(NEt2)4]single precursor를 사용하여 증착하였다. 증차고딘 박막은 SEM(Scanning Electron Microscopy)으로 surface morphology와 step coverage를 측정하였고, TEM(Transmission Electron Microscopy)분석결과 microcrystalline의 TiN을 확인하였다. XPS(X-ray Photoelectron Spectroscopy)분석결과에 따르면 $200-500^{\circ}C$구간에서는 $\beta$-hydogen elimination에 의한 반응이 일어나고 $600-700^{\circ}C$구간에서는 thermal decomposition에 의한 반응이 일어나고 있음을 알 수 있다. Carbon과 oxygen의 농도는 AES(Auger Electron Spectroscopy)를 사용하여 측정하였으며 온도가 감소할수록 carbon의 농도가 감소하는 경향을 보여주고 있다.

We fabricated IMI-O polymer containing imidazole group that can be form a complex structure between the monolayer and the metal ions at the air-water interface. Also, the monolayer behavior at the air-water interface and Langmuir-Blodget films by complexes formation have been investigated by $\pi$-A isotherms, Brewster Angle Microscopy and the scanning Maxwell-stress microscopy.

Metal oxide nanostructures have been applied to various fields such as energy, catalysts and electronics. We have freely designed one and two-dimensional (1 and 2-D) metal (transition metals and lanthanides) oxide nanostructures, characterized them using various techniques including scanning electron microscopy, transmission electron microscopy, X-ray diffraction crystallography, thermogravimetric analysis, FT-IR, UV-visible-NIR absorption, Raman, photoluminescence, X-ray photoelectron spectroscopy, and temperature-programmed thermal desorption (reaction) mass spectrometry. In addition, Ag- and Au-doped metal oxides will be discussed in this talk.

The section of Annulata under genus Hypoxylon is a member of the Xylariaceae which has ascomata with ostioles papillate ill a flattened disc. The isolates of Hypoxylon collected from the Tropic to the Temperate are compared with similar taxa and described. These isolations under Annulata section are illustrated with a light microscopy and a scanning electron microscopy. Hypoxylon archeri is newly recorded from Korea. A key to the species is also included.

The genus Hypoxylon is a member of the Xylariaceae which has brown to dark brown and pha- seoliform single cell ascospores with a conspicuous full germ slit. The isolates of Hypoxylon collected from England, Hong Kong and Korea are compared with similar taxa and described. These isolations under Hypoxylon section are detailed and illustrated, using light microscopy and scanning electron microscopy. Hypoxylon howeianum and H. rubiginosum are described and compared with former collection from Korea. A key to the species is also included.

Turning experiments are conducted to investigate characteristics of acoustic emission due to wear of the coated tool. The AE signals are obtained with a sensor attached to tool holder side. Tool states are identified with scanning electron microscopy and optical microscopy. It is demonstrated that the AE signals provide reliable informations about the cutting processes and tool states. Moreover, tool wear can be detected successfully using the AE-RMS.

Amorphous carbon nitride thin films have been deposited on silicon (100) by reactive magnetron sputtering method. The basic depositon parameters varied were the r.f. power(up to 250 W), the deposition pressure in the reactor(up to 100 mtorr) and Ar:$N_2$ gas ratio. FT-IR and X-ray photoelectron spectra showed the presence of different carbon-nitrogen bonds in the films. The surface topography of the films was studied by scanning electron microscopy(SEM) and atomic force microscopy(AFM).

In this article, the characterization of the interface of hybrid composites was discussed. Interfacial interaction in organic/inorganic hybrid composites, especially silica-containing hybrids can be characterized by fluorescence spectroscopy, small angle X-ray scattering (SAXS), scanning electron microscopy (SEM), atomic force microscopy (AFM), and $^{29}Si$ NMR spectroscopy measurements.
