  • This study analyzes the relationship between income inequality and economic growth. Gini coefficient (market income), the deciles income inequality index and per capita real GDP were analyzed. Furthermore, various cointegration tests were tried to improve the reliability of the test results. From the weak exogeniety test of between per capita real GDP and the Gini coefficient (market income), per capita real GDP has a weak exogeneity while the Gini coefficient is endogenous. From the various cointegration tests, we found out that there is a cointegration between Gini coefficient and per capita real GDP. Moreover, it is estimated that per capita real GDP has a positive effect on the Gini coefficient (market income). In the VAR Granger causal analysis, per capita real GDP affects the Gini coefficient (market income), but it is difficult to say that the Gini coefficient (market income) always has an effect on per capita real GDP. Also, the impulse-response function of the VAR model shows that per capita real GDP temporarily reduces the Gini coefficient (market income), and then increases it over time. Accordingly, it is necessary for the policies to improve not only the distribution structure but also income distribution through economic growth.

  • We compared standard culture methods as well as conventional PCR and real-time PCR for the detection of Listeria monocytogenes (L. monocytogenes) in milk, cheese, fresh-cut vegetables, and raw beef that have different levels of background microflora. No statistical differences were observed in sensitivity between the two selective media in all foods. In total, real-time PCR assay exhibited statistically excellent detection sensitivity (p<0.05) and was less time consuming and laborious as compared with standard culture methods. Conventional culture methods showed poor performance in detecting L. monocytogenes in food with high levels of background microflora, generating numerous false negative results. While the detection of L. monocytogenes in fresh cut vegetable by culture methods was hindered only by L. innocua, various background microflora, such as L. innocua, L. welshimeri, L. grayi, and Enterococcus faecalis appeared on the two selective media as presumptive positive colonies in raw beef indicating the necessity of improvement of current selective media. It appears that real-time PCR is an effective and sensitive presumptive screening tool for L. monocytogenes in various types of foods, especially foods samples with high levels of background microflora, thus complementing standard culture methodologies.

  • This study was conducted with male/female teenagers to examine the interaction between their attachment to social media and their self-identity in both real space and cyberspace. Among the subjects, male teenagers tended to use social media more than female teenagers. Also, the more friends/followers they have, the more they would use the service itself. In the subordinate correlation of the subjects' self-identity in both cyberspace and real space, most areas showed positive correlation. And each subregion of the areas of real-space ego-identity and social media addiction showed positive correlation with them as well. On the other hand, in areas of social media addiction and cyberspace ego-identity, all areas showed negative correlation except the area of dominance. Through this experiment, it was proven apparent that there needs to be proper management of teenagers that are overusing and are addicted to social media, and that programs should be developed to mediate the subjects in regards to each subregion of real space and cyberspace ego-identity.

  • 'Low Carbon, Green Growth' may be the achievable target in industry section, depending on whether less reliance on fossil-fuels use can bring higher productivity growth in the long run. This paper tests for the short-run and long-run effects of investment on energy-saving equipments on productivity growth in the Korean manufacturing industries. The investment in energy efficiency causes an increase in costs (measurement effect) in the short-run, but in the long-run likely improve energy intensity and reduce costs (positive real effect) despite the delay in new other investment for technical innovation (negative real effect). A 2SLS regression was attempted to deal with endogeneity of energy-saving investment. The productivity effects were tested for five manufacturing sub-industries showing relatively high energy intensity with annual time series data from 1982 through 2006. No productivity effects were accepted for all five sub-industries except Chemical products. Positive real effect was considered to be exceeded by negative real effect, resulting in decreased productivity growth for Chemical products.

  • The base sequences representing human- and cow-specific 168 rRNA gene markers identified in a T-RFLP analysis were recovered from clone libraries. The human- and cow-specific primers were designed from these sequences and their specificities were analyzed with fecal DNAs from human, cow, and pig. The AllBac primer set showed positive results for all human, cow, and pig samples, whereas the human-specific primer set showed positive result only for the human sample but not for the cow or pig samples. Likewise, the cow-specific primer set showed positive results only for the cow sample but not for the human or pig samples. Real-time PCR assay with these primers was developed for the identification and quantification of fecal pollution in the river water. The human- and cow-specific markers were detected in the order of 9 $\log_{10}$ copies per gram wet feces, which were two orders of magnitude lower than those of total Bacteroidales. For the river water samples, the human-specific marker was detected in $1.7-6.2\;\log_{10}$ copies/100 ml water, which was 2.4-4.9 orders of magnitude lower than those of total Bacteroidales. There was no significant correlation between total Bacteroidales and conventional fecal indicators, but there was a high correlation between Bacteroidales and the human-specific marker. This assay could reliably identify and quantify the fecal pollution sources, enabling effective measures in the watersheds and facilitating water quality management.

  • Since there is evidence that human papillomavirus (HPV) may play some role in oral carcinogenesis, we investigated the presence of HPV in a group of Pakistani subjects with normal oral cavity using real-time PCR analysis. Two-hundred patients attending the Dental Department, Sandaman Provincial Hospital, Balochistan, Pakistan, were recruited. After interview, oral epithelial cells were collected by scraping and subjected to DNA extraction. The HPV-positive DNA samples were further analyzed using primer sets specific for HPV-16 and -18. It was found that out of 200 DNA samples, 192 were PCR-positive for the ${\beta}$-globin gene and these were subsequently examined for the presence of HPV DNA. Among these, 47 (24.5%) were HPV-positive with the virus copy number ranged between 0.43-32 copies per 1 ${\mu}g$ of total DNA (9-99 copies per PCR reaction). There were 4 and 11 samples containing HPV-16 and -18, respectively. Additionally, one sample harbored both types of HPV. Among the investigated clinical parameters, smoking habit was associated with the presence of HPV (p = 0.001) while others indicated no significant association. The prevalence of HPV in normal oral cavity in our Pakistani subjects appears to be comparable to other studies. However, the association between the presence of HPV and smoking warrants further investigations whether both of these factors can cooperate in inducing oral cancer in this group of patients.

  • This research was conducted to achieve several objectives and focus research was based on financial behavior theory and prospect theory as grounded theory e.g., investigate the financial decision-making behavior between financial and real assets investment, and confirm the relationship existing between herding behavior and overconfidence factors to the level of loss and regret aversion, and financial literacy into real assets investment decisions. The study used 220 real estate auction respondents as investor samples at the State Assets and Auction Service Office Makassar, South Sulawesi, Indonesia. Data was collected through the use of a questionnaire consisting of 23 questions to measure the variables. Moreover, the research data passed through several feasibility tests like the inner and outer modeling by Partial Least Square - Structural equation model (PLS-SEM) while the hypotheses formulated were also tested to determine the magnitude of the variable relationship. Through the use of the direct and intervening test, loss and regret aversion variables have a positive and significant effect while financial literacy variables have no significant effect. There is a slight difference in the decision-making process for real assets and financial assets investors. Investment decision making behavior in the financial assets sector requires less complicated decisions compared to the decisions related to real assets investments.

  • The first D2C-era web-real variety show in Korea was broadcast via tvN of CJ E&M. The web-real variety program 'SinSeoYuGi' accumulated 54 million views, along with 50 million views at the Chinese portal site QQ. This study carries out an analysis using text mining that extracts portal site blogs, twitter page views and associative terms. In addition, this study derives viewers' response by extracting key words with opinion mining techniques that divide positive words, neutral words and negative words through customer sentiment analysis. It is found that the success factors of the web-real variety were reduced in appearance fees and production cost, harmony between actual cast members and scenario characters, mobile TV programing, and pre-roll advertising. It is expected that web-real variety broadcasting will increase in value as web contents in the future, and be established as a new genre with the job of 'technical marketer' growing as well.
