  • Purpose: This cross-sectional study was designed to identify anger-expression types of adolescent women and investigate the relationship between the identified anger-expression types and their problem behaviors and suicide probability. Methods: The participants were 942 students at two female high school located in Gwangju. The data were analyzed using descriptive statistics, cluster analysis, t-test, ANOVA, and $Scheff{\acute{e}}$ multiple comparison test. Results: Cluster analysis revealed 4 distinct anger expression types; Anger-out, Low anger expression, Anger-control, and Anger-in/out types. Female adolescent women had a higher level of trait anger or who frequently used the anger-in/out type reported internalized-externalized problem behaviors and suicide probability more frequently compared to those who frequently used the other three types of anger expression. Conclusion: Female adolescent women who had the low anger expression type and anger control type managed anger most effectively. The findings suggest the necessity of a development of the program for lowering the trait anger level and controlling the unfavorable anger expression types such as the anger-in/out.

  • Gene-expression analysis is increasingly important in biological research, with real-time reverse PCR (RTPCR) becoming the method of choice for high-throughput and accurate expression profiling of selected genes. However, this technique requires important preliminary work for standardizing and optimizing the many parameters involved in the analysis. Plant stress studies are more and more based on gene expression. The analysis of gene expression requires sensitive and reproducible measurements for specific mRNA sequence. Several genes are regulated in response to abitoic stresses, such as salinity, and their gene products function in stress response and tolerance. The design of the primers and TaqMan probes for real-time PCR assays were carried out using the Primer $Express^{TM}$ software 3.0. The PCR efficiency was estimated through the linear regression of the dilution curve. To understand the expression pattern of various genes under salt stressed condition, we have developed a unique public resource of 9 stress-related genes in poplar. In this study, real-time RT-PCR was used to quantify the transcript level of 10 genes (9 stress-related genes and 1 house keeping gene) that could play a role in adaptation of Populus davidiana. Real-time RT-PCR analyses exhibited different expression ratios of related genes. The data obtained showed that determination of mRNA levels could constitute a new approach to study the stress response of P. davidiana after adaptation during growth in salinity condition.

  • The Uncanny Valley phenomenon has already been deemed as theoretical, and the characteristics of game character expression elements for the Uncanny Valley phenomenon were recognized through case analysis as well. By theoretical consideration and case studies, it was found out that the influential elements of the Uncanny Valley phenomenon can be classified as two primary factors: character surface treatment and facial expression animation. The prepared experimental materials and adjectives were measured to be Five-Point Likert Scale. The measured results were evaluated for both influence and comparative analysis through essential statistical analysis and Repeated Measuring ANOVA in SPSS. The conclusions which were drawn from this research are as follows: The surface treatment of characters did not substantially affect the Uncanny Valley phenomenon. Instead, character's expression animation had a significant impact on the Uncanny Valley phenomenon, which also led to another conclusion that the facial expression animation had an overall deeper impact on Uncanny Valley phenomenon compared with character's surface treatment. It was the unnatural facial expression animation that controlled all of the independent variables and also caused the Uncanny Valley phenomenon. In order for game characters to evade the Uncanny Valley phenomenon and enhance game immersion, the facial expression animation of the character must be done spontaneously.

  • The purpose of this study analyzes an expression method and a characteristic of transparency of a surface in commercial space, and it is to show an index of a surface design. We did image evaluation by SD method for the commercial space which directed transparency to a surface as the method. We used a factor analysis and cluster analysis to get the image characteristic and type of the expression methods. As a result, we got six following expression methods and design indexes. (1) Transparency expression of a surface by a multiple layer. (2) Transparency expression of a surface by unification with a structure. (3) Transparency expression of a surface by transparency of materials. (4) Transparency expression of a surface by a combination of various materials. (5) Transparency expression of a surface by unification of the image media. (6) Transparency expression of a surface by transparency transformation of materials. We think that it will be able to make use of these results as a design index for the surface design of a commercial space in the future.

  • Increasing scientific evidence suggests that ribonucleotide reductase M1 (RRM1) may be a powerful predictor of survival in patients with pancreatic cancer treated with adjuvant gemcitabine-based chemotherapy after operative resection, but many existing studies have yielded inconclusive results. This meta-analysis aimed to assess the prognostic role of RRM1 in predicting survival in patients with pancreatic cancer treated with gemcitabine. An extensive literature search for relevant studies was conducted on PubMed, Embase, Web of Science, Cochrane Library, and CBM databases from their inception through May 1st, 2013. This meta-analysis was performed using the STATA 12.0 software and crude hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated. Eight clinical studies were included in this meta-analysis with a total of 665 pancreatic cancer patients treated with adjuvant gemcitabine-based chemotherapy, including 373 patients in the high RRM1 expression group and 292 patients in the low RRM1 expression group. Our meta-analysis revealed that high RRM1 expression was associated with improved overall survival (OS) of pancreatic cancer patients (HR=1.56, 95%CI=0.95-2.17, P<0.001). High RRM1 expression also was linked to longer disease-free survival (DFS) than low RRM1 expression (HR=1.37, 95%CI=0.25-2.48, P=0.016). In conclusion, our meta-analysis suggests that high RRM1 expression may be associated with improved OS and DFS of pancreatic cancer patients treated with adjuvant gemcitabine-based chemotherapy. Detection of RRM1 expression may be a promising biomarker for gemcitabine response and prognosis in pancreatic cancer patients.

  • This research is progressed to look out for efficient expression-elements of eroticism used in advertisements. Since these expressions of eroticism appealing to sex which is one of the primitive instincts of mankind are increasing in advertisements of cosmetic products which are used more often by recent high-rate-growth and the elevation of living conditions. The most usual expression-elements of eroticism in advertisement are exposure, pose, fashion style, make up, hair style and color. To analyze those expression-elements we made four pieces of fashion advertisement photos with four different types and surveyed both fashion majored students and non-fashion majored students. We applied regression analysis, ANOVA, and frequency analysis to verify the hypothesis. We found that in eroticism, the pose was the most important cognitive feature among the expression-elements and degree of cognition are varied according to major field and sexual interest. As a result, degree of cognition which effected by expression-elements will be varied even in same advertisement. In particular, convincing that the pose was the significant factor of eroticism cognition, expression of eroticism in advertisement would be more diverse and daring.

  • Cotyledonary leaves of tomato cv. Megha were transformed with the hepatitis B virus 's' gene, which encodes surface antigen. Six plant expression cassettes (pHBS, pHER, pEFEHBS, pEFEHER, pSHER and pEFESHER) were used to assay the possible expression levels by agroinfiltration. The maximum transient expression level of 489.5 ng/g D.W. was noted in pEFEHER-infiltrated cotyledonary leaves. Transgenic tomato plants with pEFEHBS and pEFEHER expression cassettes were regenerated and characterized by molecular analysis. The expression of the antigen in the fruits was confirmed by RT-PCR and ELISA analysis. This is the first report on the expression of hepatitis B surface antigen in tomato.

  • There are several existing reports of microarray chip use for assessment of altered gene expression in different diseases. In fact, there have been over 1.5 million assays of this kind performed over the last twenty years, which have influenced clinical and translational research studies. The most commonly used DNA microarray platforms are Affymetrix GeneChip and Quality Control Software along with their GeneChip Probe Arrays. These chips are created using several quality controls to confirm the success of each assay, but their actual impact on gene expression profiles had not been previously analyzed until the appearance of several bioinformatics tools for this purpose. We here performed a data mining analysis, in this case specifically focused on ovarian cancer, as well as healthy ovarian tissue and ovarian cell lines, in order to confirm quality control results and associated variation in gene expression profiles. The microarray data used in our research were downloaded from ArrayExpress and Gene Expression Omnibus (GEO) and analyzed with Expression Console Software using RMA, MAS5 and Plier algorithms. The gene expression profiles were obtained using Partek Genomics Suite v6.6 and data were visualized using principal component analysis, heat map, and Venn diagrams. Microarray quality control analysis showed that roughly 40% of the microarray files were false negative, demonstrating over- and under-estimation of expressed genes. Additionally, we confirmed the results performing second analysis using independent samples. About 70% of the significant expressed genes were correlated in both analyses. These results demonstrate the importance of appropriate microarray processing to obtain a reliable gene expression profile.
