This study was intended to investigate wether a multiculturalism education program which is integrated with age the 5 Nuri curriculum has a significant influence on promoting children's multiculturalism acceptance. The effect of the integrated multiculturalism program was studied depending on married female immigrant assistant teacher and multicultural children within a group. Three experimental groups and one comparative group were formed from 80 children whose kindergarten centers are located in southern cities of Gyeong-gi province and the convenient sampling method was used. A measurement tool for multiculturalism acceptance was used in this study, and this measurement is an amended and supplemented version of criteria aimed at children (elementary school students) developed by Kim and Chung(2010). The measurement tool was modified to make it suitable for children and consists of 33 questionnaires. All the data collected for this study was analyzed by the SPSS 20 program, the average, standard deviation, frequency, percentage. Cronbach's alpha coefficient was calculated and one-way ANOVA and ANCOVA were implemented. As for the result of the study regarding perception and relationship-building capability, the group which conducted an integrated multiculturalism education program and consisted of including a female married-immigrant assistant teacher and multicultural children (Experimental group1) showed a higher figure compared to the groups which conducted an integrated multiculturalism education program under the instruction of a female married-immigrant assistant teacher (Experimental group2), the group which conducted only the integrated multiculturalism education program (Experimental group3), and the last group which conducted only the age 5 Nuri curriculum (comparative group). As for sympathy and openness toward multiculturalism, the group which conducted integrated multiculturalism education program under the instruction of a female married-immigrant assistant teacher (Experimental group2) showed a higher figure compared to the groups which conducted an integrated multiculturalism education program including a female married-immigrant assistant teacher and multicultural children (Experimental group1), the group which conducted only an integrated multiculturalism education program (Experimental group3), and the last group which conducted only the age 5 Nuri curriculum (comparative group). As a result, the study showed that the instructor's multicultural guidance capability played a major role in the children's multiculturalism education program.

Purpose: This study was aimed to identify the difference of the self-efficacy and the health promoting behaviors between obese and normal-weight middle school students. Method: Data were collected from a convenient sample of 360 middle school students (180 normal-weight students and 180 obese students) in Pusan from November 22nd to December 20th. 2000. based on self-report questionnaires. The following instruments were used in the study after being reconstructed by the researcher with the consultation of experts and the literature review: General Self Efficacy Scale(Sherer et al.. 1982). and Health Promoting Lifestyle Profile (Walker. Sechrist & Pender. 1987). The data were analyzed with descriptive statistics, chi-square test. and t-test and Pearson's correlation coefficient. Results: 1. There were significant differences in father's obesity (p=.014) mother's obesity (p= .007), sibling's obesity (p=.00l), and school record (p=.001) between obese and normal-weight students. 2. There were statistically significant differences in the score of self-efficacy between the obese and normal-weight students (p=.0001) 3. There were statistically significant differences in health promoting behavior (p= .000) and in six sub-i terns: personal relationship (p =.000), exercise (p=.001), responsibility for health (p=.003), stress management (p = .015), self-actualization (p =.043) between the obese and normal weight students. 4. There were very statistically significant negative correlations between obesity and the self-efficacy (r=-.19. p<.001), health promoting behavior (r=-.18. p<.001), specifically personal relationship(r=-.20. p<.001), stress management (r=-.12. p<.05), responsibility for health (r=-.15. p<.01), and self-actualization (r=-.14. p<.01). Conclusion: According to the above results it is concluded that self-efficacy and health promoting behavior influence the obesity of middle school students. Therefore I recommend adding programs that can lead to improve self-efficacy and health promoting behavior to the obesity prevention programs for middle school students.

Grouting technology is one of the ground improvement methods used in water controlling and reinforcement of rock mass in underground structure construction. It is necessarily required to find out the characteristics of grout flow through discontinuities in a rock mass for an adequate grout design and performance assessment. Laminar flow is not always applicable in simulating a grout flow in a rock mass, since the rock joints usually have apertures at a micro-scale and the flow through these joints is affected by the joint roughness and the velocity profile of the flow changes partially near the roughness. Thus, the influence of joint roughness and aperture on the grout flow in rough rock joint was numerically investigated in this study. The commercial computational fluid dynamics code, FLUENT, was applied for this purpose. The computed results by embedded Herschel-Bulkley model and VOF (volume of fluid) model, which are applicable to simulate grout flow in a narrow rock joint that is filled with air and water, were well compared with that of analytical results and previously published laboratory test for the verification. The injection pressure required to keep constant injection rate of grout was calculated in a variety of Joint Roughness Coefficient (JRC) and aperture conditions, and the effect of joint roughness and aperture on grout flow were quantified.

This research is a descriptive study intended to identify the factors involved in the influence of the emotional intelligence of nursing students on their career decision-making self-efficacy and career decision levels. The correlations among the major variables were analyzed by calculating the Pearson's correlation coefficients. To identify the effects of the subjects' general characteristics and emotional intelligence on their career decision-making self-efficacy and career decision levels, a multiple regression analysis was conducted. The analysis results showed that there were positive relationships among emotional intelligence, career decision making and career decision-making self-efficacy. The factors influencing career decision-making self-efficacy were gender (${\beta}=-.155$), motivation to find employment (${\beta}=-.145$), use of emotions (${\beta}=.236$), emotional control (${\beta}=.197$), and understanding of others' emotions (${\beta}=.157$). In addition, the factors affecting the subjects' career decision level were the year level (${\beta}=.273$), motivation to find employment (${\beta}=-.145$), motivation to obtain others' recommendation (${\beta}=-.138$), and emotional control (${\beta}=.223$). Hence, sufficient endorsement from school or home is required with regard to the roles and duties of a nurse, in order to motivate future students to select the nursing degree. Furthermore, it is suggested that emotional intelligence may be improved when the degree program provides a higher proportion of emotional education.

This study examined the multicultural awareness, cultural sensitivity, and characteristics of multicultural experiences affecting the intercultural communication skills among Korean nursing students. The study participants were a total of 353 nursing students who had completed one or more clinical practice courses and were in 1 University and 2 Colleges. A self-assessment instrument was used. The descriptive statistics, t-test, one way ANOVA, Pearson's correlation coefficient, and simple and multiple regression were used to analyze the data. Statistically significant differences in the intercultural communication skill were observed in multicultural education, foreign friends, proficiency in English, stay in foreign countries, and length of stay in foreign countries. The intercultural communication skills was correlated with both multicultural awareness and cultural sensitivity. Multiple regression analysis showed that the multi-cultural awareness, multi-cultural education, and proficiency in English could explain 41.3% of the variances for the intercultural communication skill. Simple regression analysis also showed that the length of stay in foreign countries explained 2.5% of the intercultural communication skill among nursing students, who had stayed in foreign countries. Therefore, nursing educators should improve their multi-cultural awareness and develop various multi-cultural education programs, consider living abroad, and improve their language proficiency to strengthen nursing students' intercultural communication skill.

Stress history increases the residual horizontal stress of granular soil and, consequently, the penetration resistance. This study analyzes the effect of stress history on the cone resistance ($q_c$), horizontal stress index ($K_D$) and dilatometer modulus ($E_D$) of CPT and DMT from calibration chamber specimen in OC as well as NC state. Test results show that the normalized cone resistance by mean effective stress correlates well with the relative density and the state parameter, whereas the normalized cone resistance by vertical effective stress is a little affected by stress history. The influence of stress history is more reflected on $K_D$ than $E_D$ and $q_c$. The $K_D/K_0$, in which the effect of stress history on $K_D$ is compensated by the at-rest coefficient of earth pressure, $K_0$, is related to relative density, state parameter and the normalized cone resistance by mean effective stress. It is also observed that the normalized dilatometer modulus by mean effective stress ($E_D/{\sigma}_m'$) shows a unique correlation with the state parameter, regardless of stress history.

Recently, with the increasing international interest on environmental issues, efforts have been made to reduce greenhouse gas emissions due to ship fuel, however, the dependence on fossil fuel is expected to continue for a while. Since fuel costs account for a high portion of the total operating cost of a ship, it is necessary to analyze the influence of oil prices on the shipping markets. The purpose of this study is to evaluate the relationship between the international oil prices and the four major shipping markets for bulk carriers. This study employed WTI as the oil price variable while monthly data from 2017 to 2020 from the four major shipping markets by classifying freight rates, charter rates, newbuilding prices, and secondhand prices were also considered in multiple ship sizes of capesize, panamax, supramax, and handysize. Firstly, the results of the correlation analysis using the VAR model indicate that changes in international oil prices have a statistically positive (+) significant effect on BCIS only in the second time lag, on BSIS at all lags, and on BHIS only in the first staggered period. Secondly, as a result of correlation analysis using the VECM model, in the case of BPIC, BHIC, BCIN, and BHIR, the cointegration coefficient value has a negative (-) significant effect at the 5% significance level in the cointegration relationship with international oil prices. Further, in the case of the dynamic correlation, the increase in oil price in the first period of the lag leads to a decrease in the BCIN newbuilding prices while the increase in the oil price in the first and second period in the lag leads to a decrease in the BHIR used ship prices.

This study aims to investigate the characteristics and types of car accidents and establish a prediction model by analyzing 456 car accidents having occurred in the 11 tunnels in Busan, through statistical analysis techniques. The results of this study can be summarized as below. As a result of analyzing the characteristics of car accidents, it was found that 64.9% of all the car accidents took place in the tunnels between 08:00 and 18:00, which was higher than 45.8 to 46.1% of the car accidents in common roads. As a result of analyzing the types of car accidents, the car-to-car accident type was the majority, and the sole-car accident type in the tunnels was relatively high, compared to that in common roads. Besides, people at the age between 21 and 40 were most involved in car accidents, and in the vehicle type of the first party to car accidents, trucks showed a high proportion, and in the cloud cover, rainy days or cloudy days showed a high proportion unlike clear days. As a result of analyzing the principal components of car accident influence factors, it was found that the first principal components were road, tunnel structure and traffic flow-related factors, the second principal components lighting facility and road structure-related factors, the third principal factors stand-by and lighting facility-related factors, the fourth principal components human and time series-related factors, the fifth principal components human-related factors, the sixth principal components vehicle and traffic flow-related factors, and the seventh principal components meteorological factors. As a result of classifying car accident spots, there were 5 optimized groups classified, and as a result of analyzing each group based on Quantification Theory Type I, it was found that the first group showed low explanation power for the prediction model, while the fourth group showed a middle explanation power and the second, third and fifth groups showed high explanation power for the prediction model. Out of all the items(principal components) over 0.2(a weak correlation) in the partial correlation coefficient absolute value of the prediction model, this study analyzed variables including road environment variables. As a result, main examination items were summarized as proper traffic flow processing, cross-section composition(the width of a road), tunnel structure(the length of a tunnel), the lineal of a road, ventilation facilities and lighting facilities.

The Codonopsis pilosula is traditional oriental herb associated with immune-modulatory functions and has anti-inflammatory properties and antioxidative activity. The present study was conducted to investigate the effects of dietary supplementation of Codonopsis pilosula extract powder (CEP) on the immunity and productivity in sows and piglets. A total of 20 pregnant sows were randomly assigned to two dietary treatments, which was given a corn-soybean meal diet with 0% and 0.5% CEP from 40 days prepartum to weaning (25 days postpartum). The immune system of piglets was expected to build up, because the feeding of CEP might increase the colostrum contents in sows. We also predicted that the growth performance of piglets also could be increased by some compensation effects due to the increased immunity of piglets. In results, immunities of sows and piglets as well as growth performance of piglets were not affected by the supplementation of CEP. The correlation between the colostrum and the serum on the IgG contents tended to have a positive correlation, although there was no significant (coefficient, 0.435; P=0.102). This result suggests that the supplementation of CEP may increase IgG contents in sows and piglets and contribute to improve immunity of piglets. In conclusion, it is thought that the physiologically active substances of CEP did not influence to the immune synergic effects in vivo of sows. Thus, the metabolic and action mechanism of the physiologically active substances of CEP should be explored to evaluate the availability of CEP as a feed additive for the immunomodulator.
