  • Membrane-associated guanylate kinase inverted-3 (MAGI-3) is a member of the family of membrane-associated guanylate kinases (MAGUKs). MAGI-3 modulates the kinase activity of protein kinase B (PKB)/AKT through interactions with phosphatase and tensin homolog (PTEN)/MMAC. Coxsackievirus B3 (CVB3) is a common causative agent of acute myocarditis and chronic dilated cardiomyopathy. Activation of AKT and extracellular signal-regulated kinases 1/2 (ERK1/2) is essential for CVB3 replication, but the relation between MAGI-3 signaling and CVB3 replication is not well understood. This study investigated the role of MAGI-3 in CVB3 infection and replication. MAGI-3 was overexpressed in HeLa cells by polyethylenimine (PEI) transfection. To optimize the transfection conditions, different ratios of plasmid DNA to PEI concentrations were used. MAGI-3 and empty plasmid DNA were transfected into the HeLa cells. MAGI-3 overexpression alone was not sufficient to efficiently activate AKT. However, expression of the CVB3 capsid protein VP1 dramatically increased in the HeLa cells overexpressing MAGI-3 24 h after CVB3 infection. In addition, the activities of AKT and ERK were significantly induced in the CVB3-infected MAGI-3 cells overexpressing HeLa. These results demonstrate that MAGI-3 expression upregulates CVB3 replication through AKT and ERK signaling activation. MAGI-3 may be an important target to control CVB3 replication.

  • Whole soybean meju was fermented with four Bacillus strains for 45 hr in its model system. The pH range of the product was $7.98{\sim}8.68$, the contents of amino nitrogen and ammoniacal nitrogen were $286{\sim}439\;mg%,\;0.11{\sim}0.23%$, respectively and that of reducing sugar ranged $0.65{\sim}2.24%$. During fermentation, the enzyme activities increased up to $30{\sim}40\;hr$ of fermentation and slightly decreased after 45 hr. Stachyose was special sugar components for B. licheniformis and raffinose was for B. natto. The components of the organic acid showed distinctive patterns among four products and the patterns of amino acids and fatty acids were almost similar to those of other reports. The main and common odor concentrates of meju were pyrazine components, 3-methyl-1-butanol, acetic acid and ethanol. Chunggukjang, mixed with B. natto and B. licheniformis showed more acceptabilities than other combinations. Soybean paste, mixed with B. megaterium and B. subtilis, soysauce, mixed with B. megaterium and A. oryzae showed excellent acceptability, respectively.

  • Purpose - Previous studies have not paid attention to global self-corporate brand congruity and affective approach from the viewpoint of global self. This study explored an inducement of gratitude that, under the circumstance of corporate association, consumers feel toward corporate's responsible activities, pride related to corporate's ability, and global self congruity. Current researches also have examined positive behavior effects of global self-corporate brand congruity and the feelings on corporate products. Research design, data, and methodology - This research theoretically reviewed that corporate ability and social responsibility association would influence global self-corporate brand congruity, that corporate ability association could induce consumers' sense of pride, and that social responsibility association might induce gratitude. This study, furthermore, examined theoretically whether global self-corporate brand congruity, pride and gratitude could make consumers behave positively toward corporate products, and developed hypotheses. For the empirical analysis with the questionnaires, 231 employees and common people completed the questionnaires, and structural equation model of AMOS 18.0 was used. Results - From the empirical analysis, the outcomes are as followings. First, corporate ability association makes consumers feel proud. Second, corporate social responsible association makes consumers feel grateful. Third, both corporate ability association and social responsibility association let consumers be aware of global self-corporate brand congruity. Fourth, being conscious of each of pride, gratitude and global self-corporate brand congruity prompts consumers to behave positively toward corporate products. Fifth, mediation effects of pride and the congruity in the roles of corporate ability association on the positive behavior, and those of gratitude and the congruity in the roles of corporate social responsible association on the positive behavior are identified. Conclusions - Based on the results, it can be said that a marketing manager should endeavor to make consumers associate the corporate ability and social responsibility. However, the degree of consumers' feelings such as pride and gratitude can differ according to their cultural backgrounds. It is, therefore, needed to be explored by the types of feelings that can be caused more from the difference in cultural backgrounds by corporate association, and to be investigated differently and positively with behavioral effects on the corporate's products between the types.

  • Purpose - Recently, creating shared value (CSV) has attracted attention through plan sustainability and the growth of corporate management. Porter and Kramer (2011) defined the core concept of CSV as social value, economic profits, improvements in the economic social condition, and reinforcing competitiveness. The purpose of CSV, which is to pursue economic profits through a social solution to the problem, agrees with managing the objective of a social enterprise that prioritizes the pursuit of profits through the realization of a social purpose. Today, CSV studies focus on CSR and sustainability and reinforce competitiveness. However, few studies focused on the social economy. Precedent studies examined CSV using a company example, and few studies exist from the perspective of consumers and the point of view of a market society. Research design, data, and methodology - Therefore, this study examines CSV in comparison to a background of the social economy. This study also investigates and analyzes the concept of social value from the point of view of consumers, social problems, consumption value, corporate value, and the influence of consumers. This article develops three hypotheses. Hypothesis 1 investigates the correlation with social innovation that consumers thought as being necessary for social innovation by a company. Hypothesis 2 is used to confirm the influence of consumers in CSV. Therefore, this article investigates the influence of consumers on consumption action for companies that are indifferent to social problems. Hypothesis 3 is used to verify the correlation between the value that consumers demand through consumption and the corporate value that companies pursue other than profits. The three hypotheses were adopted and met the standard for suitability. Results - The importance of the CSV study from the consumer perspective was confirmed using the influence of consumers on CSV. Because the objective of company activities is either the consumer or the market, the influence that extends to interactions between the company and consumers to ensure the success of a business is significant. Regarding the CSV study, because it was an initial study, various approaches are subsequently developed. However, conceptual and practical case studies on CSV currently exist that may be used to verify the factors that comprise CSV. Therefore, the company example may enable verification of the factors that influence the composition of CSV through identification from the consumer perspective. In addition, studying CSV as an action result (of consumer satisfaction, of a company's profits and competitiveness, and of society's cancellation of a social problem) may enable the realization of a practice paradigm as opposed to simply thought and faith. Conclusions - First, this study confirms the social value of a business through the feasible and common pursuit of consumers by corporations. Second, customer influence accounts for an important part of CSV. Third, shared value commonly provides a necessary advantage to consumers, corporates, and society, and contributes to the economy and healthy social development. Fourth, corporates can conduct a business, generate profits, and realize value through improvements in social problems and by addressing their competitive strengths and weaknesses.

  • Electrophoretic comparisons of 482 individuals of Todarodes pacificus from 9 fishing areas were made to estimate genetic variability and differentiation using 17 enzymes. Strong activities were shown by 9 enzymes with 11 gene loci. The 9 sample lots could be divided into 3 genetic groups, based on dendrogram analysis using the Nei's genetic distance. The Summer, Autumn and Winter cohorts were identified as three seperated ecological populations which maintain genetic exchange. It is postulated that either the Summer cohort or the Autumn cohort has indepenently developed a local population that was isolated by hydrographic factors.

  • Mobile phone-related industries have been mainly concentrated on attracting the new customers and increasing the market share such as for the aggressive marketing activities, but it is the time to find an effective strategy to preserve existing customers since the mobile phone market had already reached the saturation. In this study, the properties of mobile phone that influence on the choice of handset and telecom company were analyzed. General properties of respondents were explored and the mobile phone properties were grouped by common factors. And analyzed the effect of factors on customer satisfaction with structural equation model. 10.4% of respondents are used their handset more than two years and 48.7% wanted to purchase other manufacturer's handset if they repurchase mobile phone. These results might come form the fact that the life cycle of mobile phone become shorter by the heating competition in mobile phone market and, to some degree, the influence of smart phone which recently become globally popular. Four factors, 'Hardware Quality', 'Practicality', 'Convergence Functions' and 'Level of Awareness', are induced from the mobile phone properties. In Structural Equation Model analysis, 'Hardware Quality' and 'Practicality' have significant and positive effects on Customer Satisfaction. But, 'Awareness' such as brand and trend appeared quite less influence on the customer satisfaction.

  • The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.

  • Objectives : Mori Radicis Cortex (MRC), the root epidermis of Morus alba L., has been traditionally used to treat lung-related diseases in Korean Medicine. The common of MRC is Mulberry bark Morus bark, and it's pharmaceutical properties and taste are known as sweet and cold, and it promotes urination and reduce edema by reducing heat from the lungs and soothe asthma. In the present study, anti-apoptotic mechanism of MRC in middle cerebral artery occlusion (MCAO) model in mice. Methods : Two-hundred grams of MRC was extracted with methanol at room temperature for 5 days, and this was repeated one time. After filtration, the methanol was removed using vacuum evaporator, then stored at $-20^{\circ}C$ until use. C57BL/6 male mice were housed in an environment with controlled humidity, temperature, and light cycle. In order to determine beneficial effects of MRC on ischemia induced brain damage, infarct volume, neurological deficit scores, activities of several apoptosis-related proteins such as caspase-8, -9, Bcl-xL in MCAO-induced brains of mice were analyzed. Mice in MRC-treated groups were orally administered 30, 100, or 300 mg/kg of body weight for three consecutive days before commencing the MCAO procedure. Results : Pre-treatment of MRC significantly reduced infarct volume in MCAO subjected mice applied with 300 mg/kg of MRC methanol extract, and MRC effectively inhibited Bcl-xL reduction and caspase-9 activation caused by MCAO-induced brain damage. Conclusions : MRC showed neuro-protective effects by regulating apoptosis-related protein signals, and it can be a potential candidate for the therapy of ischemia-induced brain damage.

  • Vegetables contain high levels of nitrate, which can be converted to nitrite for reaction with secondary amines to form nitrosamines. In this study, we evaluated safety effects against nitrite and nitrosamine as well as anti-mutagenic activities of vegetable juices. To do this, the contents of nitrate, nitrite, and nitrosamines were determined in vegetable juices. The safety effects against nitrite and nitrosamine formation were also investigated under simulated human gastric conditions. The contents of nitrate and nitrite in common and organic kale and Angelica keiskei juices were 931~2,052 mg/kg and 13~82 mg/kg, respectively. However, seven kinds of nitrosamines were not detected in the vegetables juices. The nitrate content decreased when vegetable juices were digested under simulated human gastric conditions. Nitrosamine (N-nitrosodimethylamine) formation under simulated human gastric conditions was inhibited by addition of vegetable juices. In addition, vegetable juices, especially organically cultivated juices, showed anti-mutagenic effects in a Salmonella assay system. These results suggest that organically cultivated vegetable juices are a promising health-promoting source.

  • This research was designed to compare the health condition and the quality of life of the elderly inpatients with those of the normal elderly people. The subjects of study were 482 elderly inpatients and 304 normal elderly people. The research was conducted in July and August using the instrument WHOQOL. The results of the research are as follows: For the level of health, it was recognized that male was healthier than female, having higher the education, living in the city rather than in the rural, keeping the normal life than being in the hospital. There were little difference in the past medical histories of the elderly inpatients and the normal elderly people. As to the diseases currently under the treatment, there were some difference between the elderly inpatients and the normal elderly people but the tendency was similar in the kinds and the frequencies. As to the recognition for the quality of life between the elderly inpatients and the normal elderly people based on the records reflected on each of the domains of WHOQOL, the normal elderly people more positively recognized in the overall quality of life and the following domains: physical, psychological, level of independence, and spirituality/religion/personal beliefs. The normal elderly people more positively recognized especially in the level of independence domain (mobility, activities of daily living, dependence on medication or treatments, working capacity). In the social relationships domain only the sexual activity was significant and the normal elderly people more positively recognized. The elderly inpatients showed the correlation of over 0.5 in the overall quality of life and the following domains: environment, social relationships, physical, psychological, level of independence. It was over 0.6 in the physical domain and the domains of psychological and level of independence. and the psychological domains of level of independence and social relationships. For the points of overall quality of life, it had no correlation with hospitalization but the health condition, residential district, occupation, and taste exerted a significant effect. As a result of separate analyses of the elderly inpatients and the normal elderly people, the health condition and the age only were the common variable which would exercise a significant effect. Besides, the primary factors which would exercise the quality of life were the occupation and taste for the elderly inpatients, and the residential district and source of income for the normal elderly people. In conclusion, it is first and foremost important to improve the standard of health for the overall quality of life for the elderly people, regardless of hospitalization. Therefore, a plan must be urgently drawn up for revitalization of the health promoting projects for the elderly people and the public health projects for the elderly people, and the investment must be increased for settlement of health problems of the elderly people.
