Phenoloxidase (PO), a melanin-forming enzyme around the foreign bodies, is an important component of the host defense system in invertebrates. Pro-PO is the enzymatically inactive zymogen form of PO. In the Drosophila genome, three Pro-PO isoforms have been identified to date. These include Pro-PO1 and 2, which are primarily expressed in crystal cells, and Pro-PO3, which is predominantly found in the lamellocytes. In this study, we demonstrated that Drosophila Pro-PO3, but not Pro-PO1 or 2, is enzymatically active in its zymogen form. These findings were evidenced by spectacular melanin forming capacities of various cells and tissues that overexpressed these pro-enzymes. Furthermore, the melanization phenotype observed in the lamellocyte-enriched $hop^{Tum-l}$ mutant was drastically reduced in the absence of PPO3, indicating that PPO3 plays a major role in the lamellocyte-mediated spontaneous melanization process. Taken together, these findings indicate that the biochemical properties, activation mode and in vivo role of Pro-PO3 are likely distinct from those of the other two Pro-PO enzymes involved in Drosophila physiology.

The current research examines whether consumers' preference for credit card benefits (i.e., general credit card benefits vs. credit card benefits related to green life) differs according to their pro-environmental disposition. Specifically, we predict that for consumers with high (vs. low) pro-environmental disposition, their preference for credit card benefits related to green life will be higher, while preference for general credit card benefits will not be different between low and high pro-environmental disposition groups. An online survey (N = 487) was conducted to test the hypotheses. Consistent with the hypotheses, the results indicate that (1) respondents with high pro-environmental donation intention, as compared to those with low pro-environmental donation intention, had higher preference for credit card benefits related to green life; and (2) there was no significant difference in preference for general credit card benefits between high and low pro-environmental donation intention groups. We suggest an important insight into how credit card companies approaching ESG issues can increase their consumers' preference for credit card benefits relevant to green life, considering consumers' individual differences such as pro-environmental disposition.

The purpose of this dissertation is firstly to examine the level of pro-environmental behavior of urban employed wives depending on their life style type and secondly to identify effective ways to promote their pro-environmental behavior. A structured questionnaire interview was conducted with 700 urban employed wives who lived in the Seoul Metropolitan area, and 566 of the responses were valid for analysis. For statistical analysis, this research reviewed the frequencies, percentage, mean, standard deviation(SD), Pearson's correlations, Cronbach's u, factor analysis, cluster analysis, ANOVA, $\chi$$^2$-test, Duncan's Multiple Range Test, and multiple regression using SPSS/PC WIN. The findings of analysis of the study are as follows: 1. Among life style types of employed wives, the order of ecological value was orientation type (37.3%), followed by economical value orientation type (25.8%), uninterested type (18.7%), and convenience-centric value orientation type (18.2%).Pro-environmental behavior scored relatively highly at 3.45 in average. 2. In the analysis of the relationship between life style and background variations, every variation except environmental knowledge was meaningful. 3. In the relationship between pro-environment behavior and background variations, every variation was meaningful except housing types, having helper or not, and environmental knowledge. 4. The recognition level of environmental pollution was important among the variations affecting pro-environmental behavior. 5. There was a difference in pro-environmental behaviors by the following life style types: ecological value orientation, economical value orientation, convenience centric orientation and uninterested. 6. For the relative contribution comparison of background variations (socio-economic variation and environmental variation) and life style variations to the pro-environmental behavior of urban empolyed wives, this research additionally applied each independent variable group. As a result, the explanation level drastically increased in the third step that analyzed the relationship with life style.

The purpose of this study was to assess pro-environmental behavior of elementary school students by school year and gender and to investigate the relationships of their emotional affinity toward and intellectual curiosity about life, and experiences about nature and life with the pro-environmental behavior. A total of 436 elementary students participated in the study: 189 3rd grade; 247 6th grade students, and 233 boys; 203 girls. The variables were measured by using a self-report questionnaire with 5-point Likert scale items. The results showed the levels of pro-environmental behavior of the 3rd grade students and the girls were higher than that of the 6th grade and the boys, respectively. Their pro-environmental behavior was significantly related with all measured variables. However, it was found that the direct predictors of their pro-environmental behavior were the intellectual curiosity and the indirect experience, while the emotional affinity and the direct experience did not have a direct impact on the behavior. The predictive power of the intellectual curiosity and the indirect experience for their pro-environmental behavior was higher in 3rd grade than 6th grade. While the indirect experience was a stronger predictor of the boys' pro-environmental behavior than the intellectual curiosity, the curiosity was a stronger predictor of the girls.

Proline accumulation has been shown to correlate with tolerance to drought and salt stresses in plants. We attempt to introduce the wild-type, mutant, and fusion proBA genes derived from Bacillus subtilis into Arabidopsis thaliana under the control of a strong promoter cauliflower mosaic virus 35S (CaMV35S). The transgenic plants produced higher level of free proline than control and the overproduction of proline resulted in the increased tolerance to osmotic stress in transgenic plants. Besides, the mutation in proBA genes, which were proved to lead $\alpha$-glutamyl kinase ($\alpha$-GK) reduces sensitivity to the end-product inhibition and the fusion of proB and proA also result in increasing proline production and confer osmotolerance in transgenic lines.

The experiment was conducted to evaluate Bio-V-Pro as an alternative protein source in broiler diets. Treatments were control, Bio-V-Pro 1% (BP 1), Bio-V-Pro 3% (BP 3), and Bio-V-Pro 5% (BP 5). During the starter period, all treated groups showed beter performance than control group in weight gain and feed intake (p < 0.05). The best FCR was observed in BP 1 group and the worst was found in BP 5 group. For the overall period, chicks fed BP 1 and BP 3 diets gained more than the chicks fed the control and BP 5 diets. All Bio-V-Pro fed groups consumed more feed than the control group (p < 0.05). FCR were similar between the control and BP 1 group, but BP 3 and BP 5 groups showed higher FCR than the control group. During the starter period, all BP groups showed better utilizability of crude protein, crude ash and phosphorus than the control group (p < 0.05). For the finisher period, except for the BP 5 group, the nutrient utilizability was not significantly different in most nutrients. Nutrients utilizability had a tendency (not significant) to decrease as the level of Bio-V-Pro in the diet was increased. Lysine utilizability was not affected by the dietary treatment, however, methionine utilizability was higher in BP 1 and BP 3 group than in the control group. From the results of this experiment, it seems that Bio-V-Pro is a good alternative protein source which can replace fish meal in starter diet up to 3% of the diet effectively.

Aqueous extraction of Citrus unshiu peels (AECUP) is mainly comprised with pro-angiogenichesperidin and narirutin. In this study, we report approaches to increasing the yields of extracted hesperidin and narirutinfrom Citrus unshiu peels using proper solvents. Significantly improved yields of both compounds were obtained using methanol and dimethyl sulfoxide (DMSO) compared to acetonitrile, ethyl acetate, ethanol, and isopropyl alcohol. Especially, effect of DMSO was by far the better of the two solvents in extraction of hesperidin. In addition, the DMSO extracted hesperidin significantly induced the pro-angiogenic effects of human umbilical vein endothelial cells (HUVECs) and markedly up-regulated phosphorylation of the ERK1/2 signaling pathway. These results demonstrate that pro-angiogenic inducer; hesperidin and narirutin can be simply, easily, and effectively extracted from Citrus unshiu peels.
