  • As a rise in national income has resulted in the growth in tourism demand, many studies on developing and managing tourism resources were publicized. In this context, this study was conducted to analyze the demand and willingness to pay(WTP) using contingent valuation method for agricultural experience of Daegu Urban Agriculture Park and to suggest a proper participation fee. The survey targeting Daegu citizens was performed, and we obtained 346 valid samples. We carried out the logistic analysis and figured out that sex, age, education and alienation area for urban agriculture affected to probability of agricultural experience participation. As the result of estimating willingness to pay(WTP), the measured range with this samples was from 6,052 to 16,436won. Finally, we also attained 25,000won as the proper participation fee which enables maximum revenue by conducting the scenario analysis. These findings are important in setting up the construction plan and pricing the appropriate participation fee for Daegu Urban Agriculture Park.

  • The effect of an artificial diet on developmental rate, a life history parameter, was examined for the swallowtail butterfly Papilio xuthus. Artificial insect diets are an essential component of many insect rearing systems that produce insects for research purposes. Complex agar-gelled diets are generally prepared in large batches and used shortly after preparation because the degradation of perishable diet ingredients, such as vitamins and fatty acids, can adversely affect insect quality (Brewer 1984). However, the timing of diet preparation may be inconvenient, and large batches wasteful, if the unused excess is discarded. The percentage of pupation varied considerably, with no significant differences among diets, on which a maximum pupation percentage of 83% was observed. Pellet-type diets were investigated with the aim of developing a more easily prepared diet. The extrusion of the artificial diet under high temperature and pressure may induce desirable chemical and physical changes in the extruded product. The purpose of the present study was to develop an artificial diet for rearing P. xuthus.
