  • The purpose of the study was to explore the relationships among the elementary school student's self-control, self-efficacy, and school life adjustment. For achieving the purpose, the study established three research questions: What are the relationships among self-control, self-efficacy, and school life adjustment, is there any statistically significant influence of self-control and self-efficacy on school life adjustment, and is there any mediating effect of self-efficacy in the relationship between self-control and school life adjustment, 276 fifth graders attending three elementary schools in Busan were administrated self-control scale, self-efficacy scale, and school life adjustment scale. The collected data was analyzed by correlation, stepwise multiple regression, and three-step regression analysis. And the regression analyses were separately performed on total and subscale scores. The main results were as the follows. First, there were statistically significant correlations among self-control, self-efficacy including two subscales, and school life adjustment including five subscales. Second, self-control and self-efficacy statistically and significantly influenced school life adjustment and five subscales. Finally, self-efficacy partially mediated the relationship between self-control and school life adjustment including five subscales. And discussions on the results were presented.

  • This study is intended to analyse the economic sensitivity of imported fishery products due to decrease in or elimination of tariff rates through the progress of free trade. Forty-seven species of fishes were selected for this study on the basis of the HS Code. The substitution and price effects were calculated using the price elasticities of both domestic and imported demands for fishery products under the assumption of 5% decrease in a tariff rate. Seven main economic variables were extracted from the fishery industry which can mediate the substitution and price effects. A multiple regression analysis was conducted to obtain the influence weights of these main economic variables on both effects. The order of sensitivity of the fishes was calculated using these weights. The 47 fish species were classified into four groups according to their sensitivity based on the means and the standard deviations of their total scores on seven main economic considerations. Nine fish species such as squids, hair tails, shellfishes, and crabs belonged to the hyper-sensitive group, whereas 15 fishes such as eels, sea breams, and sea weeds belonged to the sensitive group. Twelve species including common sea basses, cods, and abalones were among the less-sensitive group, and 11 species including skate rays and mud fishes comprised the non-sensitive group.

  • The purpose of this study is to investigate the effect of Brand Personality to Marine Tourism Destination Images and Intention to Recommend. For this purpose, factor analysis was applied to 42 of J.Aaker's Brand Personality Scale and 5 personality dimensions were extracted. This analysis was also applied for cognitive and affective images and two of cognitive images and three of affective images were extracted. Multiple regression was done to estimate the relative effects of Brand Personality to both cognitive and affective images and intention to recommend. The results indicated brand personality influenced on both cognitive and affective images and intention to recommend directly and also found affective images was influenced by cognitive images. The results also suggested useful insight for future study. The Brand Personality Scale which developed for the product by Aaker might not be suitable for measuring the marine tourism destination brand personality and necessary to develop the new scale suitable for marine tourism destination personality, and be needed to study together with other moderating variance such as satisfaction and congruency with image to verifying the exact effect between different variables.

  • Nursing students are exposed to a variety of stressors. The purpose of this study was to identify the factors influencing nursing students' college adjustment related to calling, work values and adaptation resources. The survey conducted in three nursing colleges (n=313) from 18th November to 30th December in 2015. The data were analyzed with descriptive statistics, independent t-tests, Pearson's correlation coefficient and multiple regression analyses using SPSS/Win 21 software. 41.9% of variance in college adjustment was accounted for by purpose/meaningfulness(t=6.871, p<.001), emotional stability(t=6.224, p<.001), altruism (t=2.708, p=.007), school year(4th)(t=3.073, p=.002), Hospitals in affiliation(t=2.822, p=.005), GPA(t=2.558, p=.011). The model was statistically significant explaining 41.9% of the variance(F=17.843, p<.001). This study suggests that a strategy increasing college adjustment for nursing students, is needed to consider purpose/meaningfulness, emotional stability, altruism.

  • This study was a descriptive study to investigate emotional labor, clinical practice stress and satisfaction of clinical practice in nursing college students. The data were collected using an self-reporting questionnaire from June 1 to July 12, 2015. Collected data were analysed on SPSS Win 20.0. The study results were summarized as follows : The students' emotional labor was $3.13{\pm}0.54$ in average on a scale of 5. The clinical practice stress was $3.65{\pm}0.47$ in average, and students' satisfaction of clinical practice was $3.41{\pm}0.43$. The emotional labor has positive correlation significantly with clinical practice stress(r=0.353, p<.001), and negative correlation with satisfaction of clinical practice (r=-0.170, p<.007). In stepwise multiple regression to put control variables, emotional labor and clinical practice stress were no significant influence toward satisfaction of clinical practice. According the result, to improve the satisfaction of clinical practices emotional labor should be released. Moreover it is necessary to attention to the health care of nursing students and it is needed to boost up the students satisfaction with major, more friendly relations should be built with co-trainees.

  • The dynamic information of radar and automatic identification system (AIS) for targets obtained from the traffic vessels operating in the north outer harbor and surrounding waters of Busan port, Korea. The target information was analyzed to investigate the potential collision risk resulting from the invalid true heading (HDT) information of AIS and the integration ambiguity in the graphic presentation of both tracked data sets for two systems. An integrated display system (IDS) for supporting the navigator of offshore fishing vessels was also developed to find possible maneuvering solutions for collision avoidance by comparing radar data with AIS data in real-time at sea. Consequently, the multiple functions of IDS can provide additional information that is potentially valuable for taking action to avoid the collision in offshore fishing vessels. However, the integration criteria of radar and AIS targets in the IDS must be carefully established to eliminate the fusion ambiguity in the graphic presentation of both AIS and radar symbols such as the one or two physical targets which are very close to each other.

  • Kelp forests and the many vital ecosystem services they provide are threatened as the severity of climate change and other anthropogenic stressors continues to mount. Particularly in the North Pacific, sea surface temperature is warming and glacial melt is decreasing salinity. This study explored the resiliency of early life-history stages of these foundation species through a factorial laboratory experiment. The effects of rising sea surface temperature under low salinity conditions on kelp spore settlement and initial gametophyte growth in Eualaria fistulosa, Nereocystis luetkeana, and Saccharina latissima were investigated. Decreased settlement and growth were observed in these species at elevated temperatures and at low salinity. Eualaria fistulosa spores and gametophytes were the most negatively impacted, compared to the more widely distributed N. luetkeana and S. latissima. These results suggest that N. luetkeana and S. latissima could potentially outperform E. fistulosa under projected conditions. However, despite decreased performance among all species, our findings indicate that these species are largely resilient to temperature changes when exposed to a low salinity, even when the temperature changes are immediate and extreme. By exploring how early life-history stages of several key kelp species are impacted by dual stressors, this research enhances our understanding of how kelp forests will respond to projected and extreme changes in temperature when already stressed by low salinity.

  • To evaluate their potential utility as an ornamental organism, novel transgenic marine medaka Oryzias dancena strains with a highly vivid fluorescent phenotype were established through transgenesis of a cyan fluorescent protein gene (cfp) driven by the endogenous fast skeletal myosin light chain 2 gene (mlc2f) promoter. The transgenic marine medaka strains possessed multiple copies of transgene integrants and passed their fluorescent transgenes successfully to subsequent generations. Transgenic expression in skeletal muscles at both the mRNA and phenotypic levels was, overall, dependent upon transgene copy numbers. In the external phenotype, an authentic fluorescent color was dominant in the skeletal muscles of the transgenic fish and clearly visible to the unaided eye. The phenotypic fluorescent color presented differentially in response to different light-irradiation sources; the transgenics displayed a yellow-green color under normal daylight or white room light conditions, a strong green-glowing fluorescence under ultraviolet light, and a cyan-like fluorescence under blue light from a light-emitting diode.
