Perceived Benefit and Perceived Risk on Mobile Shopping in Tourism and Event Products

김영국,우은주 한국이벤트컨벤션학회 2018 이벤트 컨벤션 연구 Vol.14 No.1

This study attempts to investigate whether consumers’ attitude affects intention to buy mobile shopping; to identify whether there are significant differences of consumers’ attitudes between different groups such as between shopper and non-shopper and ages groups; to make proper recommendations to mobile marketers. In this study, data is collected by using a self-administered questionnaire, and considering the whole population size and feasibility of this research. A total of 100 questionnaires were distributed, and the primary data from questionnaires were analysed by SPSS. Two factors such as benefits and risks significantly influenced intention to by mobile among demographics. Benefits turned out to be the most important factor and this result accorded with previous researches. Although the impact of risks is less than that of benefits, the impact of risks on intention is significant. Limitations and future research directions of the study were also discussed.

This study was to analyze the effects of the training of mental concentration on the learning of mathematics. The assumption was to support that the higher the level of mental concentration the higher the achievements of mathematics. For the verification of the assumption were the following five questions listed. First, how can the trained variable of mental concentration be transformable into visual abilities for reading? Second, how can the trained variable of mental concentration be transformable into reading speed? Third, how can the trained variable of mental concentration be transformable into reading comprehension? Third, how can the trained variable of mental concentration be transformable into reading comprehension? Fourth, how can the trained variable of mental concentration be transformable into the higher level of mathematics learning? Fifth, how can the trained variable of mental concentration be transformable into the higher level of school achievements? Two matched groups of junior high school students were sampled for the experiment: One was experimental group for learning mental concentration program, and the other was controlled one. It took eighty-eight days to finish experiment. To the above questions were the answeres listed as the follows: For the independent variables manipulated was it showed that the posttest scores of visual performances focussed on reading were significantly higher than the pretest ones, that the posttest scores of reading speed variable were significantly higher than the pretest ones, and that in verifying the performance of experimental group the posttest scores of reading comprehension variable were not significantly higher than the pretest ones in controlled group. For the dependent variables was is showed that there were no significant differences of mathematics performances between the experimental and control group. And that there were no significant differences of academic performances between the experimental and control group. However, the three consecutive test scores of mathematics of experimental group were higher than the controlled one from the first sessions with treatment of mental concetration through the second to the third one without no treatment. It was concluded that there could exist the differences of learning and development rate in students' traits preformed in acedemic achievements when students were taught to learn mental concentration program designed for extra-curriculum.

The purpose of this study is to investigate the effects of communication satisfaction, group cohesiveness, and job satisfaction on organizational citizenship behavior in Hotels. The results were as follows. First, communication satisfaction correlated with group cohesiveness, job satisfaction, and OCB. And, group cohesiveness and job satisfaction had positive correlation with OCB. In addition, through multiple regression analysis, the effects of communication satisfaction on group cohesiveness, job satisfaction, and OCB were examined. Second, communication satisfaction influenced OCB through group cohesiveness as an intervening factor. But, job satisfaction didn't intermediate the relationship between communication satisfaction and OCB.

Extracellular microRNAs as Biomarkers in Human Disease

김영국 전남대학교 의과학연구소 2015 전남의대학술지 Vol.51 No.2

Dysregulation of microRNA (miRNA) levels is observed in diverse disease states. Earlystudies showed that by analyzing the expression profile of miRNAs in the tissue sampleof a diseased person, it was possible to classify the disease into a specific subtype. Tobe used for diagnostic purposes more practically, however, a less invasive method thantissue biopsy is required. Surprisingly, it was discovered that a notable amount of extracellularmiRNAs circulate throughout the body fluids with high stability. Moreover,the expression profile of miRNAs was shown to differ considerably between healthyand diseased people. In addition, evidence has been accumulating of extracellularmiRNAs acting as signaling molecules between distantly located cells. If the expressionprofile faithfully reflects the disease states, the profiling of extracellular miRNAs willbecome a useful means of early warning or diagnosis of diverse diseases, replacing moreinvasive biopsy methods.

Background : Seed germination for Adenophora triphylla var. japonica Hara. is not good when grown in direct seeding. This experiment was conducted to identify seedling box suitable for seedling transplantation and cultivation to improve farm income and public health. Methods and Result : To investigate the effect on growth, sizes of seedling box used were as follows (width × length × height, in ㎝); 2.5 × 2.5 × 4 (custom), 4 × 4 × 4, 4.5 × 4.5 × 6, 5.0 × 5 × 9.6, 5 × 5 × 11.2, 5 × 5 × 17, and for sowing in narrow strips; 33.5 × 55 × 13, 33.5 × 49 × 23, 33.5 × 49 × 30. The weight of the ground part decreased as box height became lower, highest at 17 ㎝ tall (0.65 g) and lowest at 4 ㎝ (0.23 g). In terms of root length of the seedlings, the longest was 9.0 - 9.3 ㎝ at box height of 17 ㎝ and decreased as height decreased. Root weight increased as box height decreased, the highest at 4 ㎝. After the seedlings were planted, more than 90% survived in seedling box compared to the 50% rooting rate on sown in narrow strips where root net formation did not occur. During harvesting period, plant height was 15.8 - 17.5 ㎝ with a shoot diameter of 13.3 - 20.7 ㎜, leaf length of 5.6 - 7.9 ㎝ and leaf numbers 15.6 - 22.3. Moreover, leaf width was the widest at 8.6 ㎝ at 6 ㎝ box height while dry weight was the most at 6.7 g at 11.2 ㎝. Survival rate and growth characteristics of the ground part were lower in seedling box for sowing in narrow strips. For the underground characteristics, root number increased as box height decreased while dry weight increased as box height increased, with 1.7 - 3.5 and 6.2 - 6.8 less in seedling box for sowing in narrow strips, respectively. The yield in a 17 ㎝ high seedling box was 152 ㎏ per 10 a, 16% higher than conventional level, and decreased as box height decreased. Conclusion : These results suggest that the optimum seedling box height is 11.2 - 17 ㎝ to have lower root numbers and higher dry weight and yield.

Twenty corn samples from feed companies and farms were analyzed for zearlenone. Zearalenone was determined by using a high pressure liquid chromatography (HPLC) with Micropak MCH-10 column and methanol-water system and with an ultraviolet detector set at 274 ㎚. Zearalenone was detected in 8 samples at the level of 0.2-3 ㎎/Kg. And 2 samples contained more than 1 ㎎/Kg.
