Polydioxanone nanofibers for TEM observation can be produced. To collect parallelly aligned nanofibers can crystallize them partially. The SAED pattern of nanofibers drawn and/or heat-treated shows a well-developed fiber pattern, and in the patterns we can observe crystalline reflections up to third layer line.

The morphological changes of fresh beef treated with ficin(0.1% : 35$^{\circ}C$ 2hrs, 6hr,) were examined with scanning electron microscope(SEM), the results obtained were as follows ; Connective tissue protein in fresh beef treated with ficin was occurred solubilization with time and gradually trasformed from a definite form into amorphous form, followed by showing an opening-up phenomenon again and subdivision. Myofibrillar protein was cracked and breaked slightly, followed subdivision with time.

Gentiana scabra Bunge var buergeri Max, can be widely used such as cut-flower, ornamental and medicinal plant among the native plants. Microscopic and Scanning electron microscopic observation plant were carried out to estimates the characteristics correlated with germinability and germination process, and the results were as follows. The seeds were germinated just after harvest, and it means that there is no or little dormancy of the seeds. Matured seeds showed higher germinability than those of immatured. As the storage period was longer, immatured seeds showed shorter longevity than those of matured. The average longevity was about 190 days. According to the observation results of morphological changes during the germination, seed coat was expanded with water absorption immediately after seeding, and radicals were observed 2 days after seeding. Root hairs were formed behind the growing tip of the root on 4 days after seeding and cotyledon were unfolded on 6 days after seeding. In the microscopic observation of leaf tissues, it could be easily distinguished between midrib, and leaf blade, and also observed upper epidermis, palisade parenchyma and spongy parenchyma consisted as a sing1e layer. Palisade parenchyma was consisted of a single layer of cell. Stomata were restricted lower surface, arranged as anamocytic type, and surrounded by guard cells. In the microscopic anatomy of stem were consisted of cortical layer, forming a single layer of epidermis and parenchyma, and vascular bundle which was consisted of continuous cylinder of vascular tissues.
