The objective of this research is to analyze the product innovation aspect in two comparable smartphones and partly illustrate perception and preference of Vietnamese consumers of two smartphone lines of Apple - iPhone 6 Plus and Samsung - Samsung Galaxy Note 4. The research tries to clarify which innovative features in two smartphones are more preferable to a group of consumer in Vietnam. The reason why the research studies iPhone 6 Plus and Samsung Galaxy Note 4 when iPhone 7 and Samsung Galaxy Note 7 have just released is that passing more than one year is enough time for consumers to totally experience both 2 smartphone lines to give the most precise and truthful evaluation for their preferences. Moreover, iPhone 6 Plus launch signed one of the most historical memorable landmark in the development process of iPhone products when it introduced larger-screen iPhone model for the first time. It is such an important change of iPhone which could open a new continuing successful era for Apple and iPhone. The first phase of this study involves analyzing strengths and weaknesses existed considering the opportunities and threats from the competitive market, then a competitive advantage analysis is implemented for each product. The second phase conducts a survey with Vietnamese participants from different backgrounds, by which a Mann-Whitney U test will be executed to check the significant difference in opinions in different respondent groups by age and by gender to several features of two smartphones. By conducting the survey, some interesting facts revealed with the winner seemingly falling into iPhone 6 Plus. However, it still reveals some significant difference among respondent groups by age and by gender to both iPhone 6 Plus and Samsung Galaxy Note 4 in several comparing features.

We construct a deep neural network model named ECGResNet. This model can diagnosis diseases based on 12-lead ECG data of eight common cardiovascular diseases with a high accuracy. We chose the 16 Blocks of ResNet50 as the main body of the model and added the Squeeze-and-Excitation module to learn the data information between channels adaptively. We modified the first convolutional layer of ResNet50 which has a convolutional kernel of 7 to a superposition of convolutional kernels of 8 and 16 as our feature extraction method. This way allows the model to focus on the overall trend of the ECG signal while also noticing subtle changes. The model further improves the accuracy of cardiovascular and cerebrovascular disease classification by using a fully connected layer that integrates factors such as gender and age. The ECGResNet model adds Dropout layers to both the residual block and SE module of ResNet50, further avoiding the phenomenon of model overfitting. The model was eventually trained using a five-fold cross-validation and Flooding training method, with an accuracy of 95% on the test set and an F1-score of 0.841.We design a new deep neural network, innovate a multi-scale feature extraction method, and apply the SE module to extract features of ECG data.

In spite that spatial ability has been recognized as an important element of academic achievement in engineering studies, researches on the topic are rather limited in Korea. In this study, the relationship between spatial visualization skill and academic achievement of engineering students was investigated based on the several variables such as gender, high school education background and college course achievement. The result showed that there were significant relevance between spatial visualization skill and gender, high school type, achievement of high school level math & physics, and college course work grade of computer graphic and capstone design. According the case study, from the entry time of engineering college, support programs to reinforce spatial visualization skill are required for lower skill groups such as female and graduate from art course in high school. Also, college curriculum such as Engineering graphics, Capstone design are substantial to improve spatial visualization skill. However, more diversified sample groups and research methods are required in order to draw in depth results.

In addition to technical skills and competencies, communication competence has been identified to be important to engineering students who will be drivers of innovation in a rapidly changing society. Drawing on the previous studies, this research examines the results of an empirical exploration of engineering students' perception of speaking ability and their communicative competence. To date, there has been most of the research conducted on 'writing' (e.g., its educational process, class designs, ability, etc.) for engineering students. However, relatively little attention has been paid to engineering students' speaking ability perception and their competence diagnosis. This study relies on quantitative data obtained from one survey questionnaire and one test conducted respectively. The sample consists of 386 engineering students as well as 481 non-engineering students for the 1st survey. And to measure communicative competence, 150 engineering students as well as 136 non-engineering students participated in the test. Our findings show that firstly, there were significant differences in perception of speaking ability by majors and gender. Whereas there was no difference in the same survey by grade. Secondly, there was a close and significant relationship between sub-factors of speaking ability. Thirdly, there were significant differences in communicative competence by majors. Whereas there was no difference by gender and grade. Fourthly, there was a close and significant relationship between sub-factors of communicative competence. These findings are expected to provide an explanation for the improvement on engineering students' speaking ability and to encourage the participation in extra-curricular activities and programs in engineering school.

While studies have viewed the effect of Chinese talent-attracting programs launched by government since reform and open door policy, little of them has assessed these programs empirically and pertinently. This article intends to assess an important program - the Thousand Youth Talents Program (TYTP). Frist, this paper proposed a transnational migration matrix of the academics to clarify the dynamic mechanism of academic brain gain at the high end. Then, the Kaplan-Meier analysis and Cox regression model are used to empirically analyze the policy effect of TYTP. The results show that, academic ability have double edged impacts on brain gain at the high end, some scholars whose last employer's academic ranking is world's Top100 have stronger willing to return, and the negative effect of academic ranking decreases with time passing; while scholars with a tenure-track position, a tenure position or a permanent position tend to stay overseas, and the hazard rate of staying increases with age. The older scholars have more intentions to go back China, while gender was not a significant factor influencing academic return at the high end. That is, the talent-attracting programs has partly succeeded in bringing back the academics at the high end.
