Distribution of fish products from Tongyoung Marine ranching can be classified by three routes such as street-stall, live fish transportation vehicles, and wholesale markets neighboring unloading ports. These methods of distribution, however, have been restricted by limited distribution right, difficulties to differentiate fish prices from other surfaces, simple marketing channels. The ratio of cultured live fish circulated in market is increasing while naturally caught live fish is decreasing and the fresh fish shows a little of increasing rate. Consumers purchasing routes mainly depend on the live fish transportation merchants. For fresh fish traditional market plays an important role in trade. Convenience for consumers and quality of products are main factors in making decision of purchases. Bargaining power, however, belongs to the live fish transportation merchants. The demand of special markets for live fish was very strong, and the convenience and quality are relatively important required factors. Catch from Tongyoung Marine ranching has very good reputation as the possibility of being a good brand. Expecting possibility of quality differentiation was higher than price differentiation specially. The possible conclusion of a contract of a supply was suspicious however. Preliminary quality evaluation revealed that the catch is better than the cultured but worse than naturally grown fish. A merchandising is to be in a better position in the formation of prices by giving 「brand image」 to potential consumers. The target markets are retail stores such as restaurants for raw fish and final consumers. The staple markets are retail stores. Possible items of products are live fish, fresh fish for cook, and fresh fish for raw fish. It is necessary for the catch to be informed as new functional products that have been improved in safety and quality, since the product positioning is similar but not well known to consumers. To secure a brand it is required to register a trademark, eco-label product design or packing, use real name in tranction, introduce recall system, and put label. Price higher than naturally grown live fish should be targeted. Establishing broad distribution channel, wholesale market. franchise are required. To secure enough catch and control shipment of products facilities of containing live fish are necessary. Instead of dealing with live fish only, it would be better to sell fresh fish and live fish simultaneous. Strategically promotion focuses on advertisement of Marin ranching at first and then focuses on the catch from the marine ranching.

Background : Early detection and prevention of cardiac dysfunction is an important goal in the management of hypertensive patients. Doppler echocardiography was used to evaluate the pattern of left ventricular diastolic filling, however, filling indices from mitral sampling are not always nfluenced by factors related to left ventricular relaxation properties. Present study was performed to evaluate the relevance of propagation velocity to patients with hypertension by using pulsed Doppler echocardiography. Method : By using pulsed Doppler echocardiography, the velocity of left ventricular flow propagation velocity was measured from the distance and time difference of flow wave alcng the long axis propagation of left ventricular inflow during early filling in hypertensive patients (n=30 ), and M-mode echocardiographic data were obtained to evaluate mitral annulus long axis movement. Results : The values of E/A ratio, deceleration time, and left ventricular mass index were 0.82 + 0.18, 211 ± 55 msec,152 ±23 gr/m^2 respectively, and those of mitral ann ulus relaxation rate and left ventricular flow propagation velocity were 6.0 ±1.1 cm/sec and 62 ±17 cm/sec respectively. Flow propagation velocity was correlated to Doppler profiles such as E/A ratio ,r=0.47), deceleration time (r= -0.63) and mitral annulus relaxation rate (r=0.87) and also to left ventricular mass index (r= -0.69). Conclusion : left ventricular propagation velocity measurement by using pulsed Doppler echocardiography could be an important noninvasive tool in studying left ventricular diastolic function in patients with hypertension.
