  • In Korean waters, there are two color types (blue and purple) of the blue crab Portunus trituberculatus. The blue type is common, but the ratio of the purple type has increased in landings. To determine whether there were significant morphometric or genetic differences between the blue and purple types, crabs caught from the West Sea of Korea were examined. Based on covariance analysis, there were significant differences in 1 of 10 morphometric characteristics of males between the two types, in none of the ten characteristics for females. Using amplified fragment length polymorphism (AFLP) DNA fingerprinting, no specific AFLP marker was detected for each type. The heterozygosity and genetic diversity were very low. Analyses of pairwise distance, the Fst index, and genetic similarity revealed similar results, with very low genetic differentiation. Therefore, there is no significant difference between blue and purple types of the crab from the West Sea of Korea, and the two types in the West Sea can be managed as one stock.

  • In order to understand the tidal current and mean flow at the west channel of Yeoja Bay in the South Sea of Korea, numerical model experiments and vorticity analysis were carried out. The currents flow north at flood and south at ebb respectively and have the reversing form in the west channel. Topographical eddies are found in the surroundings of Dunbyong Island in the east of the channel. The flood currents flow from the waters near Naro Islands through the west channel and the coastal waters near Geumo Islands through the east channel. The ebb currents from the Yeoja Bay flow out along the west and the east channels separately. The south of Nang Island have weak flows because the island is located in the rear of main tidal stream. Currents are converged at ebb and diverged at flood in the northwest of Jeokgum Island. Tidal current ellipses show reversing form in the west channel but a kind of rotational form in the east channel. As the results of tide induced mean flows, cyclonic and anticyclonic topographical eddies at the northern tip but eddies with opposite spin at the southern tip are found in the west channel of Yeoja Bay. The topographical eddies around the islands and narrow channels are created from the vorticity formed at the land shore by the friction between tidal currents and the west channel.

  • Practice evidenced by reliable knowledge is essential for professionals and practical studies. Because nursing is a human science and practical science, theory and knowledge development is an indispensable task to improve nursing. Nursing is a very special paradigm not exactly correlated to Western medicine and Oriental medicine. However, nursing was influenced by on Western medicine at the beginning, and most nursing theories were established western philosophies. Caring is the essence of nursing. To provide qualitative care which satisfies clients, it is required to respect cultures of the clients. Western and Eastern approaches of thinking are coexisting in Korea no, so the needs for developing a nursing model, East-West Nursing, which blends two approaches are increasing. In this paper, concepts of the East-West Nursing, differences between Oriental and Western medicines, and comparison of nursing metaparadigm in prospects from and Western Philosophies were briefly covered to define the East-West Nursing. Strategies and directions to develop the East-West Nursing were also discussed.
