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.

서울지역의 소아설사환자가 가검물로부터 분리한 로타바이러스의 VP7을 코딩하는 RNA분절 cDNA를 합성한 후 로타바이러스 혈청형1인 WA1과 RE9의 아홉 번째 RNA분절과 비교하였더니 90%이상의 유사성을 보였다. 염기서열로부터 유추된 아미노산 서열중 혈청간에 변이가 많은 VR5와 VR8 지역을 비교한 결과 역시 혈청형 1인 RE9과 WA1 바이러스주와 매우 높은 유사성을 지님을 알 수 있었다.

인삼 본래의 향기 강도를 기기분석적으로 평가할 수 있는 방법을 확립하기 위해서, SPME-GC를 이용한 휘발성 향성분 분석값과 코로써 느끼는 강도와의 상관관계를 연구하였다. 여러 장소에서 재배된 인삼시료(수삼, 백삼, 홍삼)에 대한 향기성분석결과와 코로써 느끼는 측정 결과와의 상관관계를 분석해 본 결과, 백삼과 홍삼의 경우에 관능평가에 의한 향의 강도가 높으면 GC의 peak area값도 크다는 상호관계를 얻음으로써 인삼 본래 향의 강도를 객관적으로 표기 할 수 있는 계기를 마련할 수 있었다.

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.

펙틴에서 곁사슬의 정도가 다르게 제조된 사과펙틴과 토마토펙틴을 이용하여, 낮은 층밀림속도에서부터 높은 층밀림속도까지 적용이 가능한 유변학적 모델을 구하고자 하였다. 지수법칙모델, Cross 모델, Carreau 모델을 실험값에 비교하여 본 결과, Carreau 모델이 가장 적합하였다. 모델식에서 얻어진 층밀림속도 0에서의 점도$({\eta}_0)$는 곁사슬의 정도가 큰 사과펙틴의 경우에는 곁사슬이 많은 sample II가 적은 sample I보다 크게 나은 반면에 곁사슬이 적은 토마토 펙틴은 큰 차이를 보이지 않았으며, 그 값은 사과펙틴보다 크게 나타났다. 모델식의 계수를 펙틴농도에 대한 지수함수로 표현하여 펙틴에서 곁사슬의 영향을 살펴보았다. 즉, 곁사슬이 많은 사과펙틴은 토마토펙틴에 비해 유변학적 성질이 큰 차이를 보이고 있으며 모델로 설명할 수 있다.

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.
