  • This study was designed to verify the influence of mothers on their young adults in pro-environmental consuming consciousness and behavior. The compiled data are based on the responses of questionnaires from 278 young adults who reside in Seoul, Korea. The data were analyzed by frequency, standard deviation, mean, unitary dispersion, rank revolution analysis, analysis of variance (ANOVA), and multiple regression analysis by SPSS 14.0K for Windows. This study has discovered the following: First. A mother's pro-environmental consuming behavior is one of the most important factors significantly influencing a young adult's consciousness and behavior. Second. A friendly and positive consciousness about the environment enhances pro-environmental consuming behavior. A close inter-relationship exists between consciousness and behavior. However, some significant discrepancy was found between pro-environmental consuming consciousness and pro-environmental consuming behavior; that is, the level of pro-environmental consciousness was higher than the level of pro-environmental behavior. Third. Sensitivity to environmental information influenced pro-environmental consumption consciousness and behavior. Female students are more concerned about and sensitive to environmental matters than are male students. Fourth. Among the subordinate dependent variables, recycling behavior is most influenced by independent variables. Among the pro-environmental consuming behavior sector, a mother's disposal behavior exerts the most influence on the young adult's behavior. In the results of this study, it is pointed out that it is absolutely necessary fur young adults to bring up their practice level of pro-environmental purchase and consuming behaviors, and it is advised that appropriate and relevant education programs should be developed.

  • This study examines the relationship among children's smart device immersion tendency, children's self-regulation, and pro-social behavior as well as investigates the mediating effect of self-regulation between children's smart device immersion tendency and pro-social behavior. Participants were composed of 263 4-year-old children attending kindergarten in Incheon and Gyeonggi province. Data were analyzed by means of Pearson's correlation coefficients in SPSS, the structural equation model and bootstrapping in AMOS. The results are as follows. First, there is a statistically meaningful relationship among children's smart device immersion tendency, self-regulation, and pro-social behavior. There is a negative correlation between children's smart device immersion tendency and children's self-regulation as well as pro-social behavior; however, there is positive relationship between children's self-regulation and pro-social behavior. Second, children's smart device immersion tendency had a direct effect on children's self-regulation. In addition, children's self-regulation indicated a direct effect on children's pro-social behavior. Third, children's self-regulation was found sufficient to mediate the relationship between children's smart device immersion tendency and pro-social behavior. The results indicate that the effort to increase children's self-regulation may decrease the negative effect toward children's pro-social behavior caused by smart device immersion tendencies.

  • 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.

  • This study was intended to analyze the pro-environmental housing consciousness and behavior of housewives in Ulsan, Korea, according to their socioeconomic characteristics and other variables. The sample consisted of 175 housewives living in Ulsan, with descriptive analyses and multiple regressions used to analyze the aforementioned data. In general, the respondents showed high levels of pro-environmental housing consciousness and behavior. The results of the analyses indicated that the experiences of environmental education, recognition of the environment in general and pro-environmental housing consciousness were significant explanatory variables of the actual pro-environmental housing behavior. This implies that the provisions of education and information relating to the overall environment including pro-environmental housing should be emphasized.

  • In the previous study, there was a big difference between the tendency of the delivery efficiency of Yo-Pro-1 and the expression efficiency of the CFP gene, but there was a problem that could not provide a clue to this problem. Therefore, this study aimed to present a clue to this problem by quantifying and comparing the delivery efficiency after labeling DNA using a fluorescent dye, which was one of the methods for quantifying biomolecules. As a fluorescent dye for labeling, Yo-Pro-1 was used, and the delivery efficiency of the fluorescent dye Yo-Pro-1 and the labeled DNA was compared. The delivery efficiency of Yo-Pro-1 and labeled DNA according to the voltage condition of the digital electroporation system was maximized at 96 V, and the delivery efficiency tended to decrease as the voltage increased further. In the comparison of the delivery efficiency of Yo-Pro-1 and labeled DNA according to the number of voltage application conditions, the delivery efficiency was maximized at the number of 8 voltage application times for both delivery materials, and the delivery efficiency tended to decrease as the number of voltage application increases further. Through the two results, it was confirmed that the delivery efficiency using Yo-Pro-1 in the digital electroporation system represents the delivery efficiency of the system well. In addition, through the results of this study, the difference between the tendency of the delivery efficiency of Yo-Pro-1 and the expression efficiency of the CFP gene shown in the preceding study was not the result of the difference in the delivery efficiency of the delivery material, but it can be predicted to be due to a problem with the expression process of the genetic material that had been delivered.

  • The purpose of this study was to investigate influence of each file step of $ProTaper^{(R)}$ system on canal transportation. Twenty simulated canals were prepared with either engine-driven $ProTaper^{(R)}$ or manual $ProTaper^{(R)}$, Group R-resin blocks were instrumented with rotary $ProTaper^{(R)}$ and group M-resin blocks were instrumented with manual $ProTaper^{(R)}$. Pre-operative resin blocks and post-operative resin blocks after each file step preparation were scanned. Original canal image and the image after using each file step were superimposed for calculation of centering ratio The image after using each file step alld image after using previous file step were superimposed for calculation of the amount of deviation. Measurements were taken horizontally at five different levels (1 2, 3, 4 and 5 mm) from the level of apical foramen. In rotary $ProTaper^{(R)}$ instrumentation group, centering ratio and the amount of deviation of each step at all levels were not significantly different (p>0.05). In manual $ProTaper^{(R)}$ instrumentation group, centering ratio and the amount of deviation of each step at all levels except of 1 mm were not significantly different (p>0.05). At the level of 1 mn, F2 file step had significantly large centering ratio and the amount of deviation (p<0.05). Under the condition of this study, F2 file step of manual ProTaper tended to transport the apical part of the canals than that of rotary $ProTaper^{(R)}$.

  • The purpose of this study was to compare the canal configuration after shaping by ProTaper rotary files and ProTaper hand files in resin simulated canals. Forty resin simulated canals with a curvature of J-shape and S-shape were divided into four groups by 10 blocks each Simulated root canals in resin block were prepared by ProTaper rotary files and ProTaper hand files using a crown-down pressureless technique All simulated canals were prepared up to size $\#25$ file at end-point of preparation. Pre- and post-instrumentation images were recorded with color scanner. Assessment of canal shape was completed with an image analysis program. Measurements were made at 0, 1, 2, 3, 4, 5, 6 and 7 mm from the apex. At each level, outer canal width, inner canal width, total canal width, and amount of transportation from original axis were recorded. Instrumentation time was recorded. The data were analyzed statistically using independent t-test. The result was that ProTaper hand files cause significantly less canal transportation from original axis of canal body and maintain original canal configuration better than ProTaper rotary files, however ProTaper hand files take more shaping time.

  • Two diastereoisomers of cyclo(Pro-Tyr) have been synthesized simultaneously. The crystal structures and conformations of both cyclo($\small{L}$-Pro-$\small{L}$-Tyr) and a racemic mixture of cyclo($\small{D}$-Pro-$\small{L}$-Tyr) and cyclo($\small{L}$-Pro-$\small{D}$-Tyr), abbreviated as rac-cyclo($\small{D}$-Pro-$\small{L}$-Tyr/$\small{L}$-Pro-$\small{D}$-Tyr), have been determined by a single-crystal X-ray diffraction study at low temperature. The crystals of rac-cyclo($\small{D}$-Pro-$\small{L}$-Tyr/$\small{L}$-Pro-$\small{D}$-Tyr) belong to orthorhombic space group $Pna2_1$ with a = 10.755 (1), b = 12.699 (1), c = 9.600 (1) ${\AA}$ and Z = 4. The tyrosine side chain is folded towards the diketopiperazine (DKP) ring. The DKP ring adopts a twist boat conformation with pseudo symmetry $C_{2v}$. The pyrrolidine ring has an envelope conformation with the N5, C4, C7 and C8 atoms in a plane. The crystal of rac-cyclo($\small{D}$-Pro-$\small{L}$-Tyr/$\small{L}$-Pro-$\small{D}$-Tyr) is stabilized by hydrogen bonds between amide N2-H2 and carbonyl oxygen O2 in the neighbor. The hydroxyl group of tyrosine residue is also hydrogen bonded to the oxygen of the carbonyl group of the DKP ring in the next molecule. The spectroscopic properties of both isomers are also described.
