The purpose of the study is to provide the basic information for the improvement of university libraries in future. To acquire the basic information, the equipments and facilities, materials, personnels and budget elements of university are analyzed. The results of this study can be summarized as follows: 1. University outhorities primary concerned the establishment of universities rather than university libraries. 2. University libraries do not secure the facilities, materials and personnels sufficiently. 3. The realities of university libraries in Korea are very poor condition.

AC electrical properties of organic light-emitting diodes with poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylenevinylene) (MEH-PPV), poly[2,5-bia(dimethyloctylsilyl)-1,4-phenylenevinylene] (BDMOS-PPV), and tris-(8-hydroxyquinolate)-aluminum $(AlQ_3)$ as light-emitting materials are studied. The frequency-dependent real and imaginary parts of impedance were fitted using an equivalent circuit. We found that the conduction mechanism is a space-charge limited current with exponential trap distribution.

A strategy for synthesis of the furan-fused tetracyclic core of xestoquinone and halenaquinone was explored through a model study. Methyl 8-oxo-4-methyl-4-phenyl-2,7-nonadiynoate was prepared from hydratroponitrile and 3-butyn-1-ol as starting materials. The intramolecular cycloaddition of this intermediate as a key step will be involved.
