Sprites, elves and blue jets are collectively denominated as the upper atmospheric transient luminous events (TLEs). They are recently discovered optical flashes between active thunderstorms and the ionosphere. In this report, a brief introduction to the most important characteristics of TLEs is given. Since 2001, scientists from the National Cheng Kung University have been performing yearly summer campaigns from various locations in Taiwan. The main achievements of their yearly campaign are presented.

This paper concerns with the relationship between the visual perception of the degree of pucker or wrinkles of garment surfaces and the geometrical parameters of surfaces. In this study, four potentially relevant parameters of the surface profile are considered, namely, the variance (σ2), the cutting frequency (Fc), the effective disparity curvature (Dce) (Defined as the average disparity curvature of the wrinkled surface over the eyeball distance of the observer) and the frequency component of the disparity curvature ( Dcf). Based on the experiments using garment seams having varying degree of pucker (i.e. the wrinkles along a seam line), it was found that, while the logarithm of each of these four parameters has a strong linear relationship with the visually perceived degree of wrinkles, following the Web-Fetchner Law, the effective disparity curvature ( Dce) and the frequency component of the disparity curvature (Dcf) appeared to have stronger relationships with the visual perception. This finding is in agreement with the suggestion by Rogers & Cagenello that human visual system may compute the disparity curvature in discriminating curved surfaces. It also suggested an objective method of measuring the degree of surface wrinkles.

With the rapid development of the Internet, mobile Internet, big data, cloud computing and other technologies as well as the continuous improvement of logistics infrastructure, cross-border e-commerce has been developing rapidly in China. As a close neighbor of South Korea, the development of crossborder e-commerce has given wings to the development of trade between China and South Korea. Shandong Province, as an eastern coastal city of China, has a unique advantage in trade with Korea. In this paper, we will study the current situation of trade development between Shandong and Korea, analyze its problems, and put forward corresponding countermeasures and suggestions.

China and South Korea, as countries belonging to the East Asian cultural circle, have always attached great importance to education service trade. Nowadays, economic diversification has become the trend of world development, education service trade has become an important factor affecting the comprehensive strength competition between countries. China and the ROK are close in geographical location and have profound cultural origins. Over the years, the two countries have conducted fruitful bilateral cultural exchanges. This paper takes China and South Korea as the research object, and the comparative study of Sino-South Korea education service trade is of great significance to promote the development of China’s cultural products and service trade. Enhancing the competitiveness of China’s trade in cultural products and services can further improve China’s cultural soft power, so as to improve the development strategy of service trade and enhance its international influence in the context of China’s economic globalization.

Today, with the deepening cooperation between China and South Korea on public service advertising, it is very necessary to conduct a comparative study on public service advertising between China and South Korea. Due to the cultural differences between China and South Korea, there are certain differences in the theme, appeal methods and audience acceptance psychology of public service advertisements. This paper makes a comparative analysis of the two countries’ TV public service advertisements, aiming to explore the different presentation of theme design, creativity, appeal performance and advertising effect in the two countries’ TV public service advertisements and analyze the influencing factors of the difference formation, as well as to analyze and discuss the development strategies of Chinese and Korean public service advertisements.

Equatorial noise, also known magnetosonic waves (MSWs), are one of the frequently observed plasma waves in Earth’s inner magnetosphere. Observations have shown that wave amplitudes maximize at the magnetic equator with a narrow extent in their latitudinal distribution. It has been understood that waves are generated from an equatorial source region and confined within a few degrees magnetic latitude. The present study investigates whether the MSW instability and saturation amplitudes maximize at the equator, given an energetic proton ring-like distribution derived from an observed wave event, and using linear instability analysis and particle-in-cell simulations with the plasma conditions at different latitudes along the dipole magnetic field line. The results show that waves initially grow fastest (i.e., with the largest growth rate) at high latitude (20°–25°), but consistent with observations, their saturation amplitudes maximize within ±10° latitude. On the other hand, the slope of the saturation amplitudes versus latitude revealed in the present study is not as steep as what the previous statistical observation results suggest. This may be indicative of some other factors not considered in the present analyses at play, such as background magnetic field and plasma inhomogeneities and the propagation effect.

The primary objective of this study was to explore the relationship between L2 reading motivation and L2 reading strategy use. 283 Chinese college EFL students participated in this study. They answered a questionnaire with 65 items that measured the three constructs of reading motivation, reading strategy use and their self-perceived reading proficiency. Confirmatory factor analyses were applied to check the validity of each construct. Based on their motivation scores, the subjects were divided into different clusters; 22.6% of the subjects to the most highly motivated cluster; 34.4% to the moderately motivated cluster; 43.1% to the least motivated cluster. Discriminant analysis showed that such variables as advanced comprehension strategies, repetition and comprehension enhancing strategies were statistically significant variables that distinguished the three groups from each other. These results imply that EFL learners may be instructed to be aware of the importance of L2 reading motivation and L2 reading strategies for improving their L2 reading proficiency.

On November 10, 2015, the CPC Central Committee proposed a supply-side structural reform. The structural problems of China's economic development are outstanding. There is a problem of supply and demand asymmetry between the total demand shortage and the demand spillover. There is also the problem of supply and demand asymmetry in which the supply side is insufficient and the relative surplus coexist. It can be seen that the focus of the supply-side structure reform is to focus on the optimization of the economic structure. To this end, the primary task in the supply-side structural reform is to de-capacity. At the same time of de-capacity, we must actively respond to the negative impact of de-capacity. An effective measure to deal with the negative impact of de-capacity is to actively seek a stable way to resolve excess capacity while accelerating the follow-up implementation of systematic supporting measures. Taking Hebei Province as an example, the specific measures are discussed.

Purpose – This research aims to examine the effects of 3D online products presentation by comparing it with general presentation. Research design, data, and methodology – To rigorously investigate the differences of effects between 3D presentation and general presentation, this study examines the differences of the two presentations in vividness, informedness, entertainment, product trust, and purchase intention. This research designed two different forms of online product presentations, 3D and general presentation for an experiment. Results – The research findings indicate that 1) the vividness of online product presentation has a positive impact on the informedness and entertainment. While both vividness and informedness product presentation have a positive impact on product trust, the entertainment of online product presentation has no significant impact. 2) Vividness, informedness, entertainment, product trust, and purchasing intention showed significant differences between 3D and general product presentations. 3) Overall, 3D product presentation showed a stronger impact on purchasing intention than the general product presentation. Conclusions – This research expands the area of business presentation by comparing the differences of 3D and general presentation methods. This study made a great contribution to theory development, and also to guidelines for practice. These insights could be used by organizations in developing realistic environments for business presentations.

sy-2 (Seychelles-2) is a temperature sensitive natural mutant of Capsicum chinense and native to Seychelles Island in Africa. Previously we showed that sy-2 leaves were irregularly shaped and defective in chlorophyll development at temperatures below 24℃. A segregation test revealed that the sy-2 gene is controlled by a single recessive gene. To identify the sy-2 gene, we performed a map-based cloning approach using a total 600 individual F2 plants derived from crossing sy-2 and the wild type C. chinense ‘No.3341’. Fine-mapping of the locus allowed us to position sy-2 to an approximately 170-kb region flanked by markers IN2-1-1 and SNP-3-7 on chromosome 1. Among the approximately 36 hypothetical genes in this region several candidate genes including: HSP90-like ATPase family proteins, lipid-transfer proteins, calmodulin-domain protein kinases, and zinc finger proteins (ZFPs) were identified. RT-PCR and sequencing of the hypothetical genes are under way to identify sy-2.

Genome polyploidization has provided significant sources of genetic variation for plant adaptive evolution and new species formation. However, the way in which molecular evolution of polyploid genomes builds up genetic architecture underlying speciation is unclear and whether there are any differences in polyploidsubgenomes’s responses to selection is unknown. Brassica is an ideal model to address these questions. Here, we used Arabidopsis thaliana as an outgroup to conduct comparative genome analysis of newly sequenced Brassica oleracea, B. rapaand B. napus. We revealed multi-layered modes of asymmetrical interspecific and intraspecific genome evolution. Between parallel species B. oleracea and B. rapa, these layers include: asymmetrical gene retention rates,asymmetrical TE amplification, asymmetrical tandem duplication of genes and asymmetrically alternative splicing variantsbetween the two sister species; Between subgenomes within species, these layers include: massive and asymmetrical subgenomic gene loss, great variations between paralogs at the DNA sequence level, expression differentiation of triplicated, α-duplicated and tandem duplicated genes across different tissues in the two diploid species, asymmetrical recombination on A and C in B. napus. In addition, the predominant mechanism for gene loss is small deletion, rather than asymmetrical cross-over. These patterns provide new insight into genome evolution underlying speciation and trait formation and will underpin research into genetic improvement of these important crops
