The paper examines the influence of corporate governance (CG) and earning quality (EQ) on corporate value (FV) of Vietnamese enterprises. The study uses GLS regression and linear structure model using data collected from companies listing on the stock market in Vietnam during 2008-2018, with a total of 2,937 observations. The research results indicate that EQ and CG represented by the Integrated Board of Directors and the Integrated Supervisory Board have a positive effect on FV directly and indirectly. The results show that the Integrated Board of Directors has a positive effect on EQ, whereas the Integrated Supervisory Board has a negative effect on EQ. Based on the research results, we suggest that companies need to strictly comply and implement GC, so to bring down the agency cost and consequently to increase performance. The companies also should establish the Board of Director of a proper size, with financial and accounting specialty, and including women board members. The government also needs to improve the management mechanism asking for firms to prepare and publish financial statements with reliable company information, which could be provided to users. These recommendations are a useful basis to help businesses improve FV via changes in the corporate governance factors in each enterprise.

This study analyzes revenue-maximizing strategies of online auction sellers in terms of setting up starting bids and buy-it-now options. To this end, a series of field experiments is conducted where women's hair accessories of unique designs are listed in an established online auction site. The results of the experiments argue that high starting bids could increase sellers' revenue while buy-it-now options have no significant effects. Our findings suggest that online auction sellers listing items with uncertain demand - mainly individual sellers - should be cautious with auction tips which generally support low starting buds.

The paper examines the influence of internal factors and external factors on liquidity of Vietnamese listed enterprises. The study uses robust regression techniques in the fixed effects linear panel data using data collected from companies listing on the stock market in Vietnam during 2008-2019, with a total of 6,700 observations. Liquidity of Vietnamese listed enterprises is measured by current assets to current liabilities, whereas firm size, capital adequacy, profitability, leverage are used as internal determinants. Further, economic activity, inflation rate, exchange rate, and interest rate are the external factors which are considered. The research results indicate that capital adequacy, return on equity, leverage, economic activity have a positive effect on firm's liquidity, whereas return on assets and exchange rate have a negative effect on firm's liquidity and firm size, inflation rate and lending rate have no correlation with firm's liquidity. Based on the research results, the author suggests that the firms should have optimum current ratio by balancing the current assets and current liabilities in order to avoid a situation of high liquidity or low liquidity. This research seeks to bridge a gap which is present in the body of literature on listed enterprise's liquidity in Vietnam. The findings may be useful for financial managers, investors, and financial management consultants.

Glenditsia spina (GS) can resolve carbuncle, relive swelling, dispel wind and destroy parasites. For these reasons, GS has been widely used as dermatologic agent clinically. In this study, the specific pathways of anti-proliferative effect of GS on human derived melanoma cells were identified. The molecular profile was measured using microarray technique to identify up- or down-regulated genes in SK-MEL-2 cell line. Pathway analysis was done by listing percentage of pathway involvement, and the represented pathways were obtained from KEGG. The transcription factor binding sequences were obtained by Transfac database. By the promoter analysis, up-regulated genes by GS were mainly associated with MAPK, Regulation of actin cytoskeleton, Wnt, Focal adhesion and Long term potentiation pathway. Down-regulated genes by GS were mainly associated with MAPK and Antigen processing and presentation pathway. And some of the transcription factors like Sp1 and NF-Y in up-regulated genes and Oct-1 in down-regulated genes by GS also identified.

The purpose of this study is to examine Korean journals related to science education in order to analyze research trends into Nature of science in Korea. The subject of the study is the level of Korean Citation Index (KCI-listed, KCI listing candidates), that can be searched by the key phrase, "Nature of science" in Korean language through the RISS service. In this study, the Descriptive Statistical Analysis Method is utilized to discover the number of research articles, classifying them by year and by journal. Also, the Sementic Network Analysis was conducted to Word Cloud Analysis the frequency of key words, Centrality Analysis, co-occurrence and Cluster Dendrogram Analysis throughout a variety of research articles. The results show that 91 research papers were published in 25 journals from 1991 to 2015. Specifically, the 2 major journals published more than 50% of the total papers. In relation to research fields., In addition, key phrases, such as 'Analysis', 'recognition', 'lessons', 'science textbook', 'History of Science' and 'influence' are the most frequently used among the research studies. Finally, there are small language networks that appear concurrently as below: [Nature of science - high school student - recognize], [Explicit - lesson - effect], [elementary school - science textbook - analysis]. Research topic have been gradually diversified. However, many studies still put their focus on analysis and research aspects, and there have been little research on the Teaching and learning methods.

World Health Organization reveals its plan for listing 'Gaming Disorder' on the 11th International Disease Codes (ICD-11) in 2018 and it opens hot debate among scholars on its validity and timeliness. Korea, however, seems to have avoided the issue without appropriate academic refutation. In this paper, we review past academic studies related to game addiction or disorder focused on their validity of disorder measurement tools, research designs and the effect of neuroimaging studies. This analysis reveals that excessive use of gaming is not sufficient to register it as a disease and there is a risk of stigmatizing healthy gamers.

This study examines the influence of individual investors' sentiment on Japanese IPO aftermarket performance (measured by return and trading volume on the first trading day and return on the first trading year). This study proposes that IPOs will be, on average overpriced on the listing day when individual investors' sentiment is highly optimistic. Higher initial return and trading volume are expected in IPOs with higher investors' optimism. Further, the positive initial return will occur in the short term as individual investors usually are uninformed investors who demand shares based on their personal preferences, which will last only in a short period. Following the overvaluation hypothesis, price reversals should be predicted once the effect of individual investors' optimism has disappeared, causing the IPOs to underperform in the long term. Using 520 Japanese IPOs issued from January 2010 to December 2019, this study reveals that individual investors' sentiment is positively and significantly related to returns and trading volume on the first trading day. Return reversals are found on the first trading year despite the insignificant influence of individual investors' sentiment on IPO return on the first trading year.

This study aims to investigate the influence of internal factors on the bankruptcy risk of an enterprise through a sample of 439 companies listed on the Vietnamese stock exchange. The research collected secondary data from annual audited financial statements from 2008 to 2019 of listing companies. Using two different regression models with two dependent variables, six independent and control variables, we discovered that three of the model's six factors, namely return on total assets, current payment rate, and financial leverage, influence the risk of bankruptcy and account for 86.78% of the variations in firm bankruptcy risk. Financial leverage has the opposite effect on the Z-score index, increasing the risk of bankruptcy of listed firms. Return on total assets and current ratio have a positive impact on the Z-score index, reducing the risk of bankruptcy of listed companies. The findings also revealed that there is no evidence that the size of a corporation, its fixed asset investment ratio, or the size of an auditing firm have an impact on the Z-score index. These findings provide crucial evidence for business owners and managers, as well as shareholders making future capital investment decisions. Our findings can be applied to other businesses in Vietnam and similar jurisdictions.

This paper examines there is any differences among determinants of cash holdings and marginal value of cash depending on the life-cycle of firm. To accomplish these objective, we collect financial and market data of KRX listing firms for a period of 2001-2013. We present evidence of significant effect of life-cycle on the cash holdings determinants and marginal value of cash. Specially, the effect of investment opportunity related variable are varies through life-cycle. The results also suggest that marginal values of cash in the introduction stage and exit stage is higher than those in other stages. Overall, this means that the motive of cash holdings in Korean firms is weak. and shareholders place different value on a firm's cash holdings depending on the life-cycle.
