  • This research attempts to classify the types of cooperation relationship between exporting firms and logistics firms from the more objective point of view. In order to fulfill the purpose of the research, the research figures out variables influencing the types of relationship and implement a cluster analysis and t-test. The results of this research are as follows. It shows that a variety of relations exist in exporting firms and logistics firms that differently take an effect on logistics output of exporting firms. Exporting firms, building active and comprehensive relations with their logistic firms, have achieved a better foreign logistics performance than exporting firms have not. In conclusion, as a result of conducting cluster analysis based on variables representing the relationships of firms, there is a meaningful difference in the types of performance and cooperation.

The study was conducted, based on a sample of 220 students at one college and the data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise regression analysis. As a result of correlation analysis, there were significant positive correlation in difficulty of emotion regulation score and clinical practice stress score according to external control score. Factors affecting on clinical practice stress were locus of control, difficulties in emotion regulation, college satisfaction, grade, and religion having explanation rate of 17%. Therefore, to decrease clinical stress among nursing students, Nursing students should be considered the emotion regulation with external control disposition. The results can contribute as a basic data in developing education strategies and clinical adjustment programs for regulating clinical stress with emotion management and adaptation on clinical environment.

The study was composed of 125 students who were studying in 4-year system at colleges. Data were collected from September 1st to October 31st, 2019. Data analysis included an independent t-test, ANOVA, Pearson correlation coefficients and multiple regression using the SPSS 23.0 program. As a result of this study, psychological well-being of those was significantly correlated with physical health and family strenth. In a regression analysis, psychological well-being accounted for 28% of the variance of family strength, physical health and Club activity. The most significant factor affecting the success of psychological well-being was family strength (β=0.34, p<.001). The result of the study indicate the importance of consideration with family strength for psychological well-being of college students.

  • This study aims to analyse the relationship between multiple intelligence and scientific creativity of science-gifted elementary students focusing on the subject of biology. For this, 37 science-gifted fifth-graders in the Science-Gifted Education Center at an Office of Education conducted a multiple intelligence test. In addition, researchers collected science-gifted students' results of scientific creativity activity at the botanical garden field trip. The main findings from this study are as follows: First, strong intelligence was logical-mathematical intelligence for gifted students, and weak intelligence was found to be naturalistic intelligence for them. Second, there was no significant correlation in the relationship between multiple intelligence and scientific creativity of science-gifted students. Third, as a result of independent two sample t-test for each intelligence and scientific creativity scores divided into the upper and lower groups, only verbal-linguistic intelligence statistically differed significantly at the level of p<.05 (t=2.13, df=35, p=0.04). Fourth, as a result of conducting a two-way analysis to see if there were any interaction effects, verbal-linguistic and visual-spatial, logical-mathematical and visual-spatial, logical-mathematical and bodily-kinesthetic, and visual-spatial and musical-rhythmic intelligence all showed significant values at the level of p<.05 level in interaction effects on originality element comprising scientific creativity. Fifth, an analysis of students with high naturalistic intelligence showed that their scores of scientific creativity tasks conducted at the botanical garden field trip were all lower. Based on the results of this study, this study discussed the implications of scientific creativity learning linking multiple intelligence in primary science education and gifted education.

  • Speech intelligibility in patients with complete dentures is an important clinical problem depending on the material used. The objective of this study was to investigate the speech of two edentulous subjects fitted with a complete maxillary prosthesis made of two different palatal materials: chrome-cobalt alloy and acrylic resin. Three patients with complete dentures in the experiment group and ten people in the controls groups participated in the experiment. CSL, Visi-Pitch were used to measure speech characteristics. The test words consisted of a simple vowel /e/, meaningless three syllabic words containing fricative, affricated and stops sounds, and sustained fricative sounds /s/ and /$\int$/. The analysis speech parameters were vowel and lateral formants, VOT, sound durations, sound pressure level and fricative frequency. Data analysis was conducted by a series of paired T-test. The findings like the following: (1) Vowel formant one of patients with complete denture is higher than that of the control group (p<0.05), while lateral formant three of patients with complete denture is lower than that of the control group (p<0.0l). (2) Patients with complete denture produced lower speech intelligibility with low fricative frequency (/$\int$/) than control group (p<0.0). The speech intelligibility of patients with metal prosthesis was higher than that of those with resin prosthesis (p<0.05). (3) Fricative, lateral and stop sound durations of patients with complete denture were longer than those of the control group (p<0.01 and p<0.05), respectively. Total sound durations of patients with metal prosthesis were similar to that of the control group (p<0.05), while those with resin prosthesis had a shorter duration (p<0.01). This implied that those with metal prosthesis had higher speech intelligibility than those with resin prosthesis. (4) Patients with complete denture had higher sound pressure levels /t/ and /c/ than the control group (p<0.01). However, sound pressure levels for /c/ of patients with metal prosthesis or resin prosthesis was similar to the control group (p<0.05). (5) Patients with complete denture had higher fundamental frequency than the control group (p<0.01).
