  • The government of Vladimir Putin, which has been ruling Russia for a long period since 2000, has recently strived for the balanced development of underdeveloped regions and sustainable economic growth. Therefore, along with energy development in the Far East and Siberian regions, the government is promoting development projects on logistics and distribution infrastructure. It is also expanding the construction of innovative districts to develop cutting-edge technologies in the outskirts of Moscow. Amid these moves, South Korea is pushing for the New Northern Policy aimed at widening economic cooperation with European and North Asian countries to expand the scope and influence of the country's trade market. The previous year of 2020, marked the 30th anniversary of establishment of diplomatic relations between South Korea and Russia. In this context, this study was initiated to propose various measures for promoting economic cooperation and expanding trade between South Korea and Russia. Therefore, this study examined Russia's political and economic environment and explored its major industrial environment with a focus on the energy industry, innovative districts and infra facility. The study also examined the progress of a FTA between the Eurasian Economic Union, in which Russia currently takes the lead, and South Korea and recommended several measures to upgrade and accelerate economic cooperation between the two countries through research on a range of topics.

  • The physiology of most organisms, including Drosophila, is heavily influenced by their interactions with certain types of commensal bacteria. Acetobacter and Lactobacillus, two of the most representative Drosophila commensal bacteria, have stimulatory effects on host larval development and growth. However, how these effects are related to host immune activity remains largely unknown. Here, we show that the Drosophila development-promoting effects of commensal bacteria are suppressed by host immune activity. Mono-association of germ-free Drosophila larvae with Acetobacter pomorum stimulated larval development, which was accelerated when host immune deficiency (IMD) pathway genes were mutated. This phenomenon was not observed in the case of mono-association with Lactobacillus plantarum. Moreover, the mutation of Toll pathway, which constitutes the other branch of the Drosophila immune pathway, did not accelerate A. pomorum-stimulated larval development. The mechanism of action of the IMD pathway-dependent effects of A. pomorum did not appear to involve previously known host mechanisms and bacterial metabolites such as gut peptidase expression, acetic acid, and thiamine, but appeared to involve larval serum proteins. These findings may shed light on the interaction between the beneficial effects of commensal bacteria and host immune activity.

  • To screen the effective materials for hair loss treatment, the Gamissanghwa-tang extracts were tested. As a result we found that the Gamissanghwa-tang extracts have the hair growth promoting effect. After topical application of each test materials to the back of CS7BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. In the experiments of 5α-reductase type II inhibition assay, Radix Paeoniae Alba, Semen Cuscutae showed effective potential to inhibit the activity of 5α-reductase type II. And hair growth index of the Gamissanghwa-tang extracts ranked as 1.2, especially the hair growth index of Fructus Rubi is highest as 1.8. But there were no plant extracts which have effect on the DNA proliferation of hair dermal papilla cell measured by [³H]thymidine incorporation, the expression of growth factors such as IGF-I, KGF, HGF estimated by RT-PCR and protein synthesis of vibrissae hair follicle measured by [/sup 35/S] cysteine incorporation. Cortex Cinnamomi showed anti-bacterial effect on P. ovale, Radix Paeoniae Alba has the highest radical scavening activity and Radix Glycyrrhizae has the highest effects of NO synthesis. These results suggest that Gamissanghwa-tang can be used as a potent treatment agent for helping hair growth stimulation.

  • In this study, we compared growth pattern, floc yield, Exo-polysaccharides (EPS) production, Poly-${\beta}$-hydroxybutyrate (PHB) accumulation, resistance to osmotic and acid stress in Methylobacterium strains CBMB20, CBMB27, CBMB35, and CBMB110. Modified high C:N ratio medium denoted as HCN-AMS medium was used with a C:N ratio of 30:1. The HCN-AMS medium favored increased growth in all the studied strains. All Methylobacterium strains tested positive for EPS production and showed positive fluorescence with calcoflour stain. Elevated levels of EPS production from 4.2 to 75.0% was observed in HCN-AMS medium. Accumulation of PHB in HCN-AMS medium increased by 3.8, 36.7, and 12.0% in strains CBMB27, CBMB35, and CBMB110 respectively. Among the abiotic stresses, osmotic stress-induced growth inhibition of Methylobacterium strains was found to be lowered when grown in HCN-AMS medium. Likewise, growth inhibition due to acid stress at pH 5.0 was lower for strains grown in HCN-AMS medium compared to growth in AMS medium. Enhanced survivability under stress conditions may be attributed to the high EPS and PHB production at increased carbon concentration in the growth medium.

  • This study was conducted to investigate the effect of exercise on oxidative stress, nerve growth, and hepatocyte growth factors in obese children. After 12 weeks of aerobic exercise training, the aforementioned parameters before and after the training were compared. As a result, the nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) were shown to be lower in the OT than in the NT before and after the training, respectively ($p$ <0.05). The NGF was shown to have increased in both groups after the training ($p$ <0.05). The hepatocyte growth factor (HGF) was shown to be higher in the OT than in the NT before the training ($p$ <0.05), with no difference found afterwards. The malondialdehyde (MDA), ox-LDL, and 8-OHdG (Oxo-2'-deoxyguanosine) were shown to be higher in the OT than in the NT ($p$ <0.05). For ox-LDL, a difference was found between before and after the training ($p$ <0.05). The results of this study showed that obesity induced oxidative stress and caused the abnormalities of nerve and HGF secretion in obese children, and that the 12 weeks of aerobic exercise increased NGF levels, thereby promoting the development of neurogenesis in children.

  • Various methods have been used on patients with skeletal Class II division 1 malocclusion. The activator, Frankel appliance, headgear, Herbst appliance, and Twin-block appliance are some examples. The ideal treatment effect using these appliances would be to inhibit horizontal and vertical growth of the maxilla while promoting mandibular growth and obtaining optimum dentition. The Teuscher appliance has a simultaneous combined headgear effect with maxillary growth inhibition and an activator effect with mandibular growth promotion. The purpose of this study was to examine how well these effects were clinically obtained and the results are as follows. 1. The forward growth of the maxilla was effectively inhibited. 2. The downward-forward growth of the maxillary dentoalveolar complex was inhibited. 3. Growth promotion of the mandible was not observed. 4. The overjet, overbite, molar key were effectively improved. 5. The protruded upper lip and facial profile were unproved.

  • Rhizoctonia solani, Fusarium solani, F. oxysporum, and Macrophomina phaseolina were found to be associated with root rott and wilt symptoms of faba bean plants collected from different fieldes in New Valley governorate, Egypt. All the obtained isolates were able to attack faba bean plants (cv. Giza 40) causing damping-off and root rot/wilt diseases. R. solani isolates 2 and 5, F. solani isolate 8, F. oxysporum isolate 12 and M. phaseolina isolate 14 were the more virulent ones in the pathogenicity tests. Biocontrol agents (Trichoderma viride and Bacillus megaterium) and chemical inducers (salicylic acid [SA] and hydrogen peroxide) individually or in combination were examined for biological control of damping-off and root rot/wilt and growth promoting of faba bean plants in vitro and in vivo. Both antagonistic biocontrol agents and chemical inducers either individually or in combination inhibited growth of the tested pathogenic fungi. Biocontrol agents combined with chemical inducers recorded the highest inhibited growth especially in case SA + T. viride and SA + B. megaterium. Under green house and field conditions, all treatments significantly reduced damping-off and root rot/wilt severity and increased of survival plants. Also, these treatments increased fresh and weights of the survival plants in pots compared with control. The combination between biocontrol agents and chemical inducers were more effective than used of them individually and SA + T. viride was the best treatment in this respect. Also, under field conditions, all these treatments significantly increased growth parameters (plant height and number of branches per plant) and yield components (number of pods per plant and number of seeds per plant, weight of 100 seeds and total yield per feddan) and protein content in both seasons (2010~2011 and 2011~2012). Faba bean seeds soaked in SA + T. viride and SA + B. megaterium were recorded the highest growth parameters and yield components. Generally, the combination between biocontrol agents and chemical inducers recorded the best results for controlling damping-off and root rot/wilt diseases in greenhouse and field with addition improved plant growth and increased yield components in field.

  • This study discussed 'inclusive growth', which recently has gained attention as the 4th Industrial Revolution spreads, and considered innovative growth as a requirement for inclusive growth. Combining inclusiveness and innovativeness, a new concept of 'Digital New Deal' is suggested. Specifically, the new market creation strategy through digital transformation of existing industries and public sectors, and solving social problems were presented. It also analyzed problems of the past government-led top-down innovation drive and suggested the "Hybrid" approach as a new way of promoting digital New Deal. Finally, we looked at the 'job creation' effect, discussed the meaning of it in terms of inclusiveness and innovativeness, and proposed a policy alternatives to create lasting effects.
