The purpose of this paper is to verify improvement of the basic quality of food resources and make the pork legs as the more advanced food products after taking special processing steps with the mixture of traditional medical herbs and hot water extracted coffee meal. The pH level of the pettitoes(Jokbal) showed the highest rate among the control group but it showed no statistical differences in the moisture content between the control and the pettitoes(Jokbal) processed with coffee waste extract as an additional component. In addition, the levels of crude fat and crude ash showed slight increases as the addition of the amount increase. In case of the proteins, however, tendency of slight was decreased but it was not significantly difference as the amount increases. The sodium rate in the pettitoes(Jokbal) was higher in the additional group than in the control group. Texture analysis showed a tendency of wide decrease in the hardness and chewiness depending on amount of the added coffee waste extract. On the other hand, as for the cohesiveness and springiness, there was no significant difference with the control group. In case of the lightness value, as the amount of added coffee waste extract is increased from 10% to 20% and 30%, the 'L' value was reduced significantly compared to that of the control. And the 'a' value was not significantly different compared to the coffee waste extract foil impregnated furniture control. But the 'b' values were significantly increased in accordance with the result of increasing the amount of control is at the lowest level. The result may come from the influence of coffee waste extract, which affects the color of the pettitoes(Jokbal). According to the sensory evaluation, the pork part with 10% of coffee waste extract showed the highest score in looking, chewiness, smell and preference, resulting in the improvement in quality of the pettitoes(Jokbal).

Two-year experiment was conducted to investigate the effect of phosphorous, lime, increased compost, and/or boron application on the yield and quality of leaf tobacco growm in the results are summarized as follows; 1) Compared to the conventional treatment, plants grown in the treated plots in the second year showed much better growth and their yield components such as leaf area index and unit leaf weight were much greater. 2) At the end of first year crop, the pH and amount of exchangeable cations in the treated plots reached those in mature soil, but the amount of organic matter and of available phosphorous were still below those of the mature soil. Application of additional compost was more effective in enhancing soil fertility than was additional phosphorous application. 3) The yield of tobacco grown in the second year was 15-20% higher in the treated plots, compared to conventional plot, with high statistical significance. Though the quality of leaf tobacco was not significantly different among treatments, the increase of 3-7% was obtained in the treated plot. The highest total income(yield x price/kg) came from the plot treated with additional compost and phosphorous application (adjusted at 3% level on the basis of phosphorous absorption coefficient), which produced 34% more than the conventional plot.

To investigate the effects of chitosan on growth and quality improvement of vegetables, we utilized cabbage as a model plant system and SL-chitosan as a chitosan fertilizer. The chitosan fertilizer treatment increased the leaf lengths of cabbage seedlings compared with those of control groups. In addition, the content of ${\gamma}-aminobutyric$ acid (GABA) in the fertilizer-treated cabbage seedlings was higher than that in the control group. Peripheral lengths and head weights of cabbages along with their GABA contents were also measured during the growth of cabbages in field. The fertilizer treatment, without changing the physico-chemical properties of main field soil after the cultivation of cabbage, significantly increased the peripheral length, average weight and GABA content compared with control treatment. These results may suggest that the quality and quantity of cabbage can be improved by chitosan treatments.

This study was a quasi-experimental design with a non-equivalent pre-post test that verified the effect of formative feedback practice on practice satisfaction, learning motivation and academic self efficacy for nursing students. 37 were assigned to an intervention group and 41 to a control group. Formative feedback practice was applied to intervention group and peer review smartphone videos was applied to control group. Data were analyzed using the SPSS/WIN 22.0 program. There was no significant difference in learning motivation between the groups, but there were a significant difference in practice satisfaction(t=-2.79, p=.007) and academic self efficacy(t=2.30, p=.024) between the pre-post scores of the experimental group. This is meaningful in that it is more effective to provide formative feedback practice than to provide peer review smartphone videos. Therefore, it is necessary to consider formative feedback practice for the acquisition of core fundamental nursing skills of nursing students.
