Background: Epidural steroid injections (ESIs) have been widely used in managing spinal pain. Dexamethasone has recently emerged as a useful drug in this setting, relative to particulate steroids, although the associated systemic effects have not been fully elucidated. This study aimed to investigate the incidences and types of systemic effects after fluoroscopically guided ESI with dexamethasone. Methods: This retrospective study included 888 ESIs with dexamethasone (fluoroscopically guided at the cervical and lumbosacral levels) performed on 825 patients during January to June 2017. Data regarding systemic effects were collected via telephone interviews using a standardized questionnaire at 2 weeks after the procedure. Data on patient demographic, clinical, and procedural characteristics were collected and analyzed to identify factors that were associated with systemic effects. All statistical analyses were performed using the chi-squared test. Results: Among the 825 patients, 40 patients (4.8%) experienced systemic effects during the 2-week follow-up period. The most common systemic effect was facial flushing (12 patients, 1.5%), which was followed by urticaria (7 patients, 0.8%) and insomnia (7 patients, 0.8%). A history of spine surgery was significantly associated with the occurrence of systemic effects (P = 0.036). Systemic effects were significantly more common for injections at the cervical level than at the lumbar level (P = 0.019). Conclusions: Approximately 4.8% of the patients who underwent ESI with dexamethasone experienced minor and transient systemic effects. These effects were more common in patients who had undergone a previous spine surgery or received a cervical ESI.

Although there have been plenty of dominance deviation analysis, few studies have dealt with multiple phenotypes. Because researchers focused on multiple phenotypes (final weight and backfat thickness) of Landrace pigs, the classification of the genes was possible. With genome-wide association studies (GWASs), we analyzed the additive and dominance effects of the single nucleotide polymorphisms (SNPs). The classification of the pig genes into four categories (overdominance in final weight, overdominance in backfat thickness and overdominance in final weight, underdominance in backfat thickness, etc.) can enable us not only to analyze each phenotype's dominant effects, but also to illustrate the gene ontology (GO) analysis with different aspects. We aimed to determine the additive and dominant effect in backfat thickness and final weight and performed GO analysis. Using additive model and dominance deviation analysis in GWASs, Landrace pigs' overdominant and underdominant SNP effects in final weight and backfat thickness were surveyed. Then through GO analysis, we investigated the genes that were classified in the GWASs. The major GO terms of the underdominant effects in final weight and overdominant effects in backfat thickness were ion transport with the SLC8A3, KCNJ16, P2RX7 and TRPC3 genes. Interestingly, the major GO terms in the underdominant effects in the final weight and the underdominant effects in the backfat thickness were the regulation of ion transport with the STAC, GCK, TRPC6, UBASH3B, CAMK2D, CACNG4 and SCN4B genes. These results demonstrate that ion transport and ion transport regulation genes have distinct dominant effects. Through GWASs using the mode of linear additive model and dominance deviation, overdominant effects and underdominant effects in backfat thickness was contrary to each other in GO terms (ion transport and ion transport regulation, respectively). Additionally, because ion transport and ion transport regulation genes are associative with adipose tissue accumulation, we could infer that these two groups of genes had to do with unique fat accumulation mechanisms in Landrace pigs.

Purpose - This study aimed to analyze the dynamic effects of progress in globalization on firm performance by employing individual companies' financial statement datasets. Design/methodology - The analysis leveraged the variables of operating revenue (OPRE) and pre-tax profit and loss (PLBT) as measurement variables for firm performance over 2011-2019. As a proxy variable for globalization, the trade index, a subordinate indicator of the KOF Globalization Index, was used. Through panel regression analysis, the relationship among those variables was ascertained, and the local projection (LP) method was subsequently utilized to identify dynamic effects. A subsample analysis was further performed by classifying companies based on their sizes and industries to determine the differential effects of globalization on each group. Findings - The panel regression analysis derived positive effects of an increasing degree of globalization on OPRE of Korea maritime and fishery firms. However, the impulse response functions, obtained from the LP, showed that in the short run, globalization affects PLBT negatively but in the long run, it gradually converted into a positive effect. In addition, according to the subsample analysis based on company size, the effects of globalization on OPRE became greater as each company became larger. Moreover, the industry-based analysis showed heterogeneous effects, depending on the industries in which the maritime and fishery companies operated. Originality/value - The analysis of the dynamic effects of globalization on firm performance, which revealed that the effects vary depending on the time points, is the important contribution of this study. The results also suggest that the effects of globalization vary depending on the company size and industry.

Objective: The purpose of this study was to test the mediating effects of ego-resilience on relationship between perceived parenting attitudes and regulatory focus among college students. Methods: In this study, 256 college students were surveyed. The collected data were put through correlation analysis using PASW Statistics 18.0. In addition, 3-stage multiple regression analyses and the Sobel test were used to test any mediating effects. Results: The findings show that the diversity of concerns and interests, emotion control, and positive future orientation, the subfactors of ego-resiliency, all have partial mediating effects on the relationship between father's care and promotion focus. Only positive future orientation had partial mediating effects on the relationship between mother's care and promotion focus. Conclusion: Father's care turned out to be an independent variable to explain better the mediating effects of ego-resiliency on relations between parenting attitudes and regulatory focus, which implies the influence and importance of father's care on college students.

Objectives: The purpose of the present study was to investigate the antidiarrheal effects of Anjang-san in mice and rats. Methods: We measured the content of condensed tannin in Anjang-san extract, and observed the effects of Anjang-san on the small intestinal and colonic transport of mice, as well as on mice models of diarrhea induced by castor oil and $MgSO_4$, and on rat models of castor oil-induced enteropooling. Results: Anjang-san showed significant inhibitory effects on abnormally increased small intestinal transit induced by pyridostigmine and neostigmine, and inhibitory effects on large intestinal transit. Anjang-san also exhibited antidiarrheal effects on diarrhea induced by $MgSO_4$, and inhibitory effects on castor oil-induced enteropooling. Anjang-san also improved castor oil-induced diarrhea based on simple numbers without statistical significance. Conclusion: These results demonstrate that Anjang-san has significant antidiarrheal properties and attests to its possible utility in functional diarrheas, irritable bowel syndrome and other gastrointestinal disorders based upon further studies.

Estimations of paddy field area are important for agricultural water supply planning. Especially these estimations have to be excused by drainage basin. In this research, we developed a paddy field estimation model considering shift-share effects such as national growing, structural, local effects. National growing effects are estimated by adopting the result of KREI-ASMO model which predict farm land area in national level. Paddy field structural effects are estimated using statistical data about farmhouse numbers and cultivation areas. Local allocation effects are calculated by differences of estimations and real data. The results using data from 1998 to 2003 show that developed model estimates 2006 paddy field areas in each province in 5% error and is applicable to predict future change of paddy field.

In this paper, we showed parasitic effects in the millimeter wave package, and proposed a suppression method of parasitic effects using Si lossy layer. From CB-CPW used as a transmission line of the MIMIC package, PPL mode is generated and this causes the parasitic effects considered from this paper. Parasitic effects caused by PPL mode such as resonance, radiation, and crosstalk in the single and multi-chip package ran affect to the performance of MIMIC seriously. To suppress these parasitic effects, we adapted Si lossy layer $\rho$ . The PPL mode can be suppressed by the lossy layer, and it eliminates the parasitic effects. It is expected that showed results ran be used as luxurious data for design MIMICs and various types of millimeter wave applications.
