Author co-citation analysis with 20 authors from Korean Nutrition Literature were executed. The purpose of this study is to examine the meaning of bibliographic phenomena in Korean literature by co-citation and to approach the intellectural structure of nutrition field in view of multidimensional space. The analysis assumes that the more two author are cited together, the closer the relationship between them. The raw data are co-citation counts from the Korean Journal of Nutrition over the period 1986~1987. The resulting map shows (1) identifiable author groups of nutrition, (2) locations of these groups with respect to each other, (3) the degree of centrality and peripherality of author within groups, (4) the relationship between domestic authors and foreign authors.

Purpose: This study evaluates the level of cultural competence (CC) and educational needs for cultural competence in nursing (CCN) in undergraduate nursing students. Methods: A self-report instrument was used to measure CC and educational needs for CCN. Questionnaires were completed by 330 nursing students in three nursing colleges. Descriptive statistics, a t-test, an ANOVA, Pearson correlation analyses, and multiple regression were used to analyze the data. Results: The mean CC score was 2.99 and the mean CCN educational needs score was 7.1. CC positively correlated with educational needs for CCN. The regression model explained 36% of the variance in CC. Factors affecting CC were school grades, multicultural education experience, frequency of meeting foreigners, length of encounters with foreigners, foreign-language fluency, and degree of interest in multicultural nursing. Conclusion: To strengthen the CC of students, nursing educators should develop an educational program for CCN and incorporate CCN into nursing school curricula.

The cDNA of RNA segment coding for VP7 of human rotavirus isolated from patient's stool at Seoul area was synthesized, amplified by polymerase chain reaction, field in with Klenow fragment of DNA polymerase I and cloned into pUC19. The cDNA sequence was determined and compared with that of VP7 coding RNA segments of group A rotaviruses isolates in foreign country. Over 90% sequence homology was found with serotyppe I sepcific WA1 and RE9 strains. Comparative analysis of the deduced amino acid sequences within the two variable regions (amino acid residue 87 through 101 and 208 through 221) with WA1 and RE9 strains also showed high degree of sequence similarity with each other.

Ginsengs grown fur six years at different locations were harvested and prepared for white and red ginsengs. These fresh, white, red, and other ginsengs purchased from domestic and foreign countries were analyzed for their volatile compounds by solid phase microextraction-gas chromatography (SPME-GC) and SPME-GC/mass spectrometery (MS). The intensity of the ginseng volatiles perceived by nose was also measured in order to correlate the intensity with the corresponding GC analysis. Good correlations were obtained between the GC peak area and the degree of intensity evaluated by sensory panelists, indication that a reliable and objective evaluation of the aroma intensity of ginsengs by a simple GC analysis is possible.

As China has quickly emerged as a global economic power, the total number of international commercial disputes arbitrated by Chinese arbitral institutions has increased dramatically. Along with this, the annulment procedure of arbitral awards in China have been newly brought to the fore. In accordance with the historical background and the demand of the times, the Chinese annulment procedure of arbitral awards reveals distinctive Chinese features. Although it was enacted in the face ofof an unwarranted prejudice against the dispute settlement system by arbitration as well as a deep mistrust of domestic arbitral institutions, the annulment procedure of arbitral awards showed a certain degree of justification and rationality in its initial stages of legislation. However, it is also the case that it has not adapted well to new domestic or foreign arbitration circumstances in the last twenty years. At present, there is a keen interest in revisions to and debates on arbitration law of China. It is necessary to take an active part in the amendment discussion and process of arbitration law. Moreover, we need to reform the annulment procedure of arbitral awards in order to meet the global trend of arbitration law.

The rheological properties of apple pectins and tomato pectins with different degrees of side branches (sample I and sample II) were investigated with wide range of shear rate by theological modeling. Among the Power law model, Cross model and Carreau model, the Carreau model was the best fitted to the experimental data. Increasing in branching of apple pectins resulted in higher zero-shear viscosity $({\eta}_0)$. But, tomato pectins that have a low degree of side branches were shown litte difference between sample I and sample II. It is concluded that side branches of pectins can result in significant difference in rheological properties. And, this is predicted by the Carreau model.

This study investigates the key determinants of exchange rate (RER) misalignment for the period 1991 to 2020. The BEER technique has been used to estimate the degree of the equilibrium exchange rate. To explore the actual exchange rate misalignment and to assess the behavior of variables that are different in different regimes of undervaluation and overvaluation, the nonlinear technique of Markov regime-switching (MSM) was applied. The mean and variance of each regime are highly significant and show that undervaluation episodes have a low mean (116.139) and more volatility (1.229) while overvaluation episodes have a high mean (126.732) with less volatility (0.871). The findings show that MSM accurately identifies exchange rate misalignment in both regimes as separate incidents of overvaluation and undervaluation. Results further depict that misalignment of the RER is affected by terms of trade, net foreign assets, interest differential, government investment, and consumption decision. Results recommend that if policymakers want to use the exchange rate as a policy tool, they must first consider the drivers of the equilibrium exchange rate. As a result, any deliberate actions to address exchange rate misalignment must focus on the underlying fundamentals that drive the exchange rate.

Purpose: The purpose of this study were to identify degree and the relationship between of self-efficacy, social support, and academic stress of nursing college students. Method: This study was a descriptive research study to analyze the factors affecting academic stress. Data were collected by structured questionnaires from June 10 to 30, 2020. The survey conducted an online survey of 159 students in D and B city. Data were analyzed descriptive statistics, Pearson's correlation coefficient, and Stepwise multiple regression Results: Academic stress were correlated with self-efficacy(r=-.41, p<.001) and social support(r=-.40, p<.001). In a multiple regression, self-efficacy(β=-.170, p=.010), social support(β=-.137, p=.042) were associated academic stress. These factors attributed to 22.2% of the total variance in academic stress. Conclusion: Therefore the factors affective intervention techniques need to be applied to the development of programs to upgrade mental health academic stress of nursing students.

This study aims to measure the lower tail dependence as risk contagion from the U.S. economy to 18 developing countries affecting FDI inflows using time-series data from 2005 to 2019. Firstly, we utilize four dynamic copula models, namely, Student-t, Clayton, rotated survival Gumbel, and rotated survival Joe, to measure the tail dependence structure between the U.S. and each developing country's real GDP growth. Secondly, we use the regression model to explore the contagion effects on FDI inflows. The results show that there is evidence of the tail dependence between the U.S and developing economies, indicating the presence of the contagion effects. Primarily, we observe that the degree of contagion effects of the global financial crisis varies across countries; a strong impact is observed in Chinese, South African, Russian, Colombian, and Mexican economic growth. Furthermore, we found significant contagion risk affecting FDI inflows positively in China, Indonesia, Columbia, Morocco, and negatively in the Philippines, Bulgaria, and South Africa. This study demonstrates the usefulness of the copulas model in terms of examining contagion. Our findings shed light on the influence of sound policies and regulations to cope with both positive and negative consequences of the contagion on the capital movement.

Purpose - This paper analyzes how Research and Development (R&D) cartelization and Research Joint Ventures (RJV) affect firms that engage in Cournot competition in their product market using a model in which the Home and Foreign firm produce differentiated products and export their total output to a third country's market. Design/Methodology - In a two-stage game, research expenditures incurred in the first stage improve product quality and are subject to various degrees of spillovers. We consider four different scenarios. Findings - In a symmetric equilibrium we observe the following: (i) an RJV that cooperates in R&D decision yields the highest R&D expenditure. However, the scenario which yields the lowest expenditure depends on the extent of differentiation between the goods and the degree of spillovers; (ii) RJV cartelization yields the highest product quality, output, and consumer surplus in the third country; however, the lowest is produced by R&D competition if spillovers are strong and by R&D cartelization if spillovers are weak; and (iii) each firm's profit is at its minimum in R&D competition and its maximum in RJV cartelization. Furthermore, if spillovers are strong, the profit of each firm in R&D cartelization is greater than that in RJV competition, and vice versa. Originality/value - By analyzing product innovation in international markets, we can find similarities and differences between process R&D and product R&D in international markets.
