  • Purpose - Organizational individuals can gain profit from any trials and errors concerning the knowledge others have been able to accumulate. The culture also states the organizational behaviors by identifying the principal aims, and the way members handle personal relationships. This study aims that how corporate cultures can be connected with particular occupations. Research design, Data, and methodology - For the systematic review in prior literature dataset, the present author used the PRISMA which is a set of items that are evidence-based and utilized in reporting systematic reviews. It includes the reporting of meta-analyses. Result - The present author figured out that corporate culture is one of the most crucial factors that workers consider in deciding whether or not they want to be employed in an organization. Having an excellent corporate culture sets the company apart from the competition and increases the company's status to new positions of recruiting and business success Conclusion - The current research concluded that possessing an excellent corporate culture positions the company apart from the competition but boosts the company to new recruiting and business success levels. The two traits of an excellent corporate culture include the culture allowing every individual in the organization to succeed, and the culture works for every individual involved.

  • Recently, as an enonomic importance of the Eurasian Continent raises, the necessity of east-west connecting ancient transport roads research is increasing. Although domestic research of eastern-western international exchange in the Eurasia is not yet very active, the studies of history, archaeology, art history, folklore, costume history have been advanced steadily. An attention for the exchange through steppe route originated from the interest in Korean folk and Korean culture and the research range is extending to Xiungnu, Kurgan culture as a direct investigation on the remains of Mongolia and Kazakhstan has been achieved constantly. The art history has been leading the research of exchange which is based on desert and oasis. The field research of Iran, Uzbekistan, Azerbaijan, etc progressed in various routes, and the research on diverse topics including Silla's golden culture, transmission of glass, and the Buddhism is improving. Research on the maritime silk road is weaker, compared to other parts. Buddhist and Hindu temples of Southeast Asia attracted some interest to people, but the research should focus on the restoration of sea route and consideration of its meaning. Research of this part is expected to be more activative, as domestic researchers investigate Don Son culture and Sa Huynh culture of Vietnam by themselves. From now on, we should focus on topics that are not directly connected to Korean history, and Korean culture. Because it is also our duty to study and conserve the culture of entire human community.

  • During the screening of antiviral substances having inhibitory effects on Tobacco mosaic virus (TMV) infection on tobacco plants, we found a bacterial isolate KTB3, and identified it as Acinetobacter sp. which strongly inhibited the infection of TMV When the culture filtrate from KTB3 was applied on the upper surface of the Xanthi-nc tobacco leaves at the same time, or 24 hours before TMV inoculation, almost complete inhibition was achieved. Likewise, 86% inhibition was achieved, when the culture filtrate was applied on the underside of the leaves. In field trials, transmission of TMV from diseased seedlings to healthy ones during transplanting work was reduced by 92%, when the culture filtrate was sprayed onto the tobacco seedlings, cv. NC82, 24 hours before transplanting. No toxic effect was observed on the tobacco plants. Antiviral substance from the culture filtrate was purified by ethanol precipitation, dialysis, DEAE-cellulose, and Sephadex G75 gel column chromatography. The partially purified active material which showed positive color reaction to sugar and protein inhibited TMV infection by 60% at 1 ${\mu}$g/ml.

  • In order to maximize the secretory expression of human serum albumin (HSA) in the yeast Saccharomyces cerevisiae, a series of HSA expression vectors were constructed with a combination of different promoters, 5' untranslated regions (5'UTR), and secretion signal sequences. The expression vector composed of the galactose-inducible promoter GALl0, the natural 5'UTR, and the natural signal sequence of HSA directed the most efficient expression and secretion of HSA among the constructed vectors when introduced into several S. cerevisiae strains. Although the major form of HSA expressed and secreted in the yeast transformants was the mature form of 66 kDa, the truncated form of 45 kDa was also detected both in the cell extract and in the culture supernatant. The level of the intact HSA protein in the culture supernatant reached up to 30 mg/l at 24 h of cultivation in a shake-flask culture but began to decrease afterwards, indicating that the secreted HSA protein was unstable in a prolonged culture of yeast.

  • In hypoxic tissue conditions, pyruvate can not enter the Krebs cycle and lactic acid, produced from pyruvate, accumulates to induce lactic acidosis. Pyruvate, However, can also be converted to alanine by glutamate pyruvate transaminase, that could be enhanced by glutamate. Therefore, it would be a fundamental measure to treat the lactic acidosis in tissue hypoxic conditions when one can convert the accumulated lactic acid, through pyruvate, to alanine. To test the above hypothesis, we induced a lactic acidosis in cats and the effect of glutamate on recovery of acid base state and removal of the lactic acid from blood were assessed and the results were compared with those of bicarbonate administration, which is one of the most frequently used conventional measure for correction of the acid base state during lactic acidosis. The results were that glutamate and combined glutamate bicarbonate solutions not only restored the acid base status completely from the lactic acidosis in an hour or two, but also restored the blood level of lactate partially. We concluded that administration of glutamate solution to convert pyruvate into alanine is effective in preventing lactic acid accumulation and treating lactic acidosis.

  • Three flavonoid compounds - quercetin, luteolin, and kaempferol - were analyzed from two commercially available concentrated pomegranate extracts produced in Turkey and Italy, respectively. The samples were freeze-dried and hydrolyzed by 0.4 M hydrochloric acid in 50% ethanol at $80^{\circ}C$. HPLC (high-performance liquid chromatography) with DAD (diode array detection) at a wavelength of 260 nm was used for the detection of the three flavonoids. The detection limits of the three compounds were in hundreds of picograms and the signal-to-noise ratio ranged from 4 to 5: quercetin: >308 pg, s/n=4.0; luteolin: >262 pg, s/n=4.5; kaempferol: >688 pg, s/n=5.0. Quercetin, but not luteolin and kaempferol, was detected in the both pomegranate extracts. The concentrations of quercetin were $49.7\;{\mu}g/g$ and $27.7\;{\mu}g/g$ in the two pomegranate extracts made in Turkey and Italy, respectively.

  • Providing variable load for testing a motor in high speed conditions is usually a difficult task. The eddy current brake can be used in application of load testing of motors. This paper deals with construction of a novel claw pole eddy current brake which is employed as a load for a DC counter rotating motor (CRM). These kinds of motors have two inner and outer shafts that rotate in opposite directions simultaneously, which are particularly suitable for under water propulsion systems. The prototype 45KW eddy current brake consists of two parts. One of them is installed on the inner shaft of the 60KW DC CRM and the other one is installed on its outer shaft. The simulation and experimental results with prototype brakes are also analyzed by using MATLAB/Simulink and the operational characteristic of the brake is demonstrated as a function of the motor speed and current of the magnetic poles.

  • Protein S-glutathionylation is a reversible post-translational modification on cysteine residues forming a mixed disulfide with glutathione. S-glutathionylation, not only protects proteins from oxidation but also regulates the functions of proteins involved in various cellular signaling pathways. In this study, we developed a method for the detection of S-glutathionylated proteins (ProSSG) using eosin-glutathione (E-GSH) and mouse glutaredoxin 1 (mGrx1). ProSSG was efficiently and specifically labeled with E-GSH to form ProSSG-E via thiol-disulfide exchange. ProSSG-E was readily luminescent allowing the detection of ProSSG with semi-quantitative determination. In addition, a deglutathionylation enzyme mGrx1 specifically released E-GSH from ProSSG-E, which increased fluorescence allowing a sensitive determination of ProSSG levels. Application of the method to the adipocyte differentiation of 3T3-L1 cells showed specific detection of ProSSG and its increase upon differentiation induction, which was consistent with the result obtained by conventional immunoblot analysis, but with greater specificity and sensitivity.

  • Tetranectin (TN), an adipogenic serum protein, enhances adipocyte differentiation, however, its functional mechanism has yet to be elucidated. In the present study, we investigated the adipogenic function of TN by using medium containing TN-depleted fetal bovine serum (TN-del-FBS) and recombinant mouse TN (mTN). The adipocyte differentiation of 3T3-L1 cells was significantly enhanced by mTN supplementation essentially at differentiation induction, which indicated a potential role of the protein in the early differentiation phase. The adipogenic effect of mTN was more significant with insulin in the differentiation induction cocktail, implicating their close functional relationship. mTN enhanced not only the proliferation of growing cells, but also mitotic clonal expansion (MCE) that is a prerequisite for adipocyte differentiation in the early phase. Consistently, mTN increased the phosphorylation of ERK in the early phase of adipocyte differentiation. Results of this study demonstrate that the adipogenic function of mTN is mediated by enhancing MCE via ERK signaling.
