The global environment is rapidly changing due to the Coronavirus outbreak, especially in areas that have been relatively neglected, such as border areas. In particular, In the post-COVID era, the border area between the two Koreas requires a new perception and conceptualization as a space for reconciliation, cooperation and coexistence. Through the status and outlook of post-COVID era, this paper analyzed the promoting directions of each situation, such as SWOT analysis, depending on the characteristics of changes such as domestic preference, changes into standards of new national competitiveness, changes into regional value chains, and the transition to digital economy in the era of the Fourth Industrial Revolution. Based on the previous analysis, this paper proposed realistic approaches such as the utilization of buffer zones, expansion of non-political cooperation to prepare resilience, and promotion of new growth engine industries. In addition, this paper suggested prepared strategies for analyzing the influence of positive and negative cases and responding to them by writing possible scenarios.

In order to isolate thermophilic compost-promoting bacteria with high activity of cellulase and xylanase, spent mushroom substrates with sawdust were collected from mushroom cultivation farm, Jinju, Gyeongnam in Korea. Among of the isolates, one strain, designated SJ21 was selected by agar diffusion method. The strain SJ21 was identified as members of the Bacillus lincheniformis by biochemical characteristics using Bacillus ID kit and VITEK 2 system. Comparative 16S rDNA gene sequence analysis showed that strain SJ21 formed a distinct phylogenetic tree within the genus Bacillus and was most closely related to Bacillus subtilis with 16S rDNA gene sequence similarity of 99%. On the basis of its physiological properties, biochemical characteristics and phylogenetic distinctiveness, strain SJ21 was classified within the genus Bacillus, for which the name Bacillus sp. SJ21 is proposed. The cellulase and xylanase activity of Bacillus sp. SJ21 was slightly increased according to bacterial population from exponential phase to stationary phase in growth curve for Bacillus sp. SJ21.

Stress and its related hormones epinephrine (E) and norepinephrine (NE) play a crucial role in tumor progression. Macrophages in the tumor microenvironment (TME) polarized to M2 is also a vital pathway for tumor deterioration. Here, we explore the underlying role of macrophages in the effect of stress and E promoting breast cancer growth. It was found that the weight and volume of tumor in tumor bearing mice were increased, and dramatically accompanied with the rising E level after chronic stress using social isolation. What is most noteworthy, the number of M2 macrophages inside tumor was up-regulated with it. The effects of E treatment appear to be directly related to the change of M2 phenotype is reproduced in vitro. Moreover, E receptor $ADR{\beta}2$ involved in E promoting M2 polarization was comprehended simultaneously. Our results imply psychological stress is influential on specific immune system, more essential for the comprehensive treatment against tumors. [BMB Reports 2015; 48(5): 295-300]

This study was conducted to investigate determinants of intention of smoking cessation behavior. We sampled 204 university student smokers using questionaires and analyzed the data using the t-test, ANOVA, Pearson product-moment correlation, and multiple regression. The results are as follows: 1. The attitudes concerning smoking cessation behavior are related to a student's course of study, religion and is further related to whether or not they tried to stop smoking. The subjective norm is related to smoking cessation recommendations. Perceived behavioral control is related to a growth criterion, the smoking amount and whether or not they have tried to stop smoking. The intention of smoking cessation behavior is related to smoking amount and whether or not they nare tried to stop smoking. 2. Total symptom number is related to smoking amount and smoking period. 3. Total symptom number is related to behavioral belief, attitude, and the intention to stop smoking. In conclusion, it was found that university students smoke far too much, however the intention to stop smoking is very low. Therefore, an intention promoting program of smoking cessation behavior is needed to reduce the smoking rate and relaxation therapy is necessary for in changing health promoting habits.

Purpose: The purpose of this study was to identify the relationship between self efficacy (SE), health promoting behaviors (HPB) and symptoms of stress (SOS) among university students. Method: Data was collected by questionnaires from 369 university students in Seoul, Korea. Data was analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. Results: The mean score for SE was 3.42, the mean score for HPB was 2.48, and the mean score for SOS was 2.31. The score of SOS showed a significantly negative correlation with the score of SE (r=-.24, p=.00) and HPB (r=-.13, r=.00). Also, SOS showed a significantly negative correlation with diet HPB (r=-.15, p=.00), spiritual growth HPB (r=-.17, p=.00), interpersonal relationship HPB (r=-.17, p=.00), and stress management HPB (r=-.10, p=.04). The most powerful predictor of SOS was SE and the variance was $10\%$. A combination of SE, diet, problems related to drinking, and responsibility for health HPB account for $16\%$ of the variance in SOS among university students. Conclusion: This study suggests that SE and HPB are significant influencing factors on SOS among university students.

In this study, we analyzed the amino acid contents of corn to provide basic data for promoting the use of proteins in livestock. The present study was done to examine the amino acid contents of the corn 'Gwangpyungok' grown in a natural field at the National Institute of Animal Science, Cheonan province, Korea, in 2016. Gwangpyungok, which is Korean corn cultivar, was used as the sample to provide basic data for promoting the use of proteins in livestock by analyzing the amino acid contents of each part of corn as a breed that is adaptable to the environment of Korea. The asparagine acid content was the highest in the leaf blade among the parts of corn, and the glutamic acid content was the highest in the corn ear, stem, leaf sheath, corn bract and inflorescence. The essential amino acids in the corn ear, leaf blade and inflorescence revealed that their contents were in the following order: leucine > phenylalanine > valine > threonine > lysine > isoleucine, and in the inflorescences and stem, leaf sheath and corn bract, their contents were in following order: leucine > valine > phenylalanine > threonine > lysine > isoleucine. Therefore, further research on the nutritional aspects of forage must be performed because livestock growth is influenced by the nutritive value of the various parts of forage.

Activation of the Wnt/β-catenin pathway plays a pathogenic role in age-related macular degeneration (AMD) and is thus a potential target for the development of therapeutics for this disease. Here, we demonstrated that Wnt5a antagonized β-catenin response transcription (CRT) induced with Wnt3a by promoting β-catenin phosphorylation at Ser33/Ser37/Thr41 and its subsequent degradation in human retinal pigment epithelial (RPE) cells. Wnt5a decreased the levels of vascular endothelial growth factor (VEGF), tumor necrosis factor-α(TNF-α), and nuclear factor-κB (NF-κB), which was up-regulated by Wnt3a. Furthermore, Wnt5a increased E-cadherin expression and decreased cell migration by down-regulating Snail expression, thereby abrogating the Wnt3a-induced epithelial-mesenchymal transition (EMT) in human RPE cells. Our findings suggest that Wnt5a suppresses the pathogenic effects of canonical Wnt signaling in human RPE cells by promoting β-catenin phosphorylation and degradation. Therefore, Wnt5a has significant therapeutic potential for the treatment of AMD. [BMB Reports 2015; 48(9): 525-530]

The increased potential for the lifespan of a child with cancer is largely due to advances in drug treatment, radiation treatment, and surgical techniques. In this generation cancer has become associated with chronic illness. Therefore supportive nursing intervention for children with cancer is needed to promote normal growth and development. This study was designed to develop and test the supportive nursing intervention program for promoting body image and self-esteem of children with cancer The supportive nursing intervention program involved emotional, physical, informational, and social support. The subjects were 41 children with cancer(20 in intervention group, 21 in control group) in K city. Measurements were taken concerning body image and self-esteem from both groups during pre and post test The data were analyzed using Cronbach's alpha, x$^2$-test, paired t-test and t-test. The results were as follows : The intervention group had a more positive body image as measured by the Body Cathexis Scale (t＝2.436, p＝.020) and a more self esteem as measured by the Cpopersmith self-inventory (t＝2.768, p＝.009) than the control group at post test. According to this study, the supportive nursing intervention program was effective for promoting the body image and self-esteem of children with cancer. Repeated research is needed to develop a refined supportive nursing intervention program for children with chronic illness.

Bone grafts are essential for promoting bone healing in some orthopedic cases, and synthetic bone materials have been widely used for bone defects. In addition, osteoinductive proteins such as bone morphogenetic protein and fibroblast growth factor promote osteoblast differentiation and proliferation. The combination of these factors is very useful clinically for promoting bone healing. In this study, we report the use of synthetic bone materials and osteoinductive proteins to repair bone defects in two dogs.
