    In this study, the check-all-that-apply (CATA) method, headspace solid phase microextraction (HS-SPME)-Arrow combined with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-mass spectrometry-olfactometry (GC-MS-O) were used to analyze volatile flavor substances that affect the sensory differences among milk from four pastures. The results of the CATA questionnaire showed that milky aroma, creamy aroma, fragrant and sweet aroma, milky aroma, plastic odor, cooked odor and metallic odor were significantly different among the four milk samples (P < 0.05), and milk from pasture I were the most preferred by respondents, and the preference scores of milk from pastures III and IV were lower. Totally 14 aroma-active substances with an aroma intensity greater than or equal to 1 were obtained from the four milk samples through olfactometry. Using partial least squares regression analysis (PLSR), correlation analysis among sensory data, aroma-active substances and milk samples was conducted. The results showed that milky and creamy aroma from pasture I were prominent, which was strongly correlated with 2-heptanone, butanoic acid, decanoic acid, and hexanoic acid. Milk from pasture II showed a fragrant and sweet aroma, which may be related to the concentration of limonene. Milk from pasture III had prominent metallic, plastic, and milky odors, which may be related to 1-octene-3-alcohol. Milk from pasture IV had a cooked odor, which mainly came from hexanal and styrene

    A Sketch-Based Approach for Interactive Organization of Video Clips

    With the rapid growth of video resources, techniques for efficient organization of video clips are becoming appealing in the multimedia domain. In this article, a sketch-based approach is proposed to intuitively organize video clips by: (1) enhancing their narrations using sketch annotations and (2) structurizing the organization process by gesture-based free-form sketching on touch devices. There are two main contributions of this work. The first is a sketch graph, a novel representation for the narrative structure of video clips to facilitate content organization. The second is a method to perform context-aware sketch recommendation scalable to large video collections, enabling common users to easily organize sketch annotations. A prototype system integrating the proposed approach was evaluated on the basis of five different aspects concerning its performance and usability. Two sketch searching experiments showed that the proposed context-aware sketch recommendation outperforms, in terms of accuracy and scalability, two state-of-the-art sketch searching methods. Moreover, a user study showed that the sketch graph is consistently preferred over traditional representations such as keywords and keyframes. The second user study showed that the proposed approach is applicable in those scenarios where the video annotator and organizer were the same person. The third user study showed that, for video content organization, using sketch graph users took on average 1/3 less time than using a mass-market tool Movie Maker and took on average 1/4 less time than using a state-of-theart sketch alternative. These results demonstrated that the proposed sketch graph approach is a promising video organization tool

    An Interactive SpiralTape Video Summarization

    A majority of video summarization systems use linear representations, such as rectangular storyboards and timelines at linear scales. In this paper, we propose a novel nonlinear dynamic representation called SpiralTape that summarizes a video in a smooth spiral pattern. SpiralTape provides an unusual and fresh activity suitable for stimulating environments such as science and technology museums, in which children or young individuals can have enjoyable experiences that create meaningful learning outcomes. In addition, SpiralTape provides an uninterrupted overall structure of video content and takes design principles including compactness, continuity, efficient overview, and interactivity into consideration. A working SpiralTape system was developed and deployed in pilot applications and exhibitions. Elaborate user studies with evaluation benchmarks on multiple metrics were conducted to compare SpiralTape with two representative linear video summarization methods and a state-of-the-art radial video visualization. The evaluation results demonstrate the effectiveness and natural interaction performance of SpiralTape.</p

    Given the unprecedented and profound impact on the traditional sports industry and its economic driving force brought by the “Internet +”, the purpose of this study is to explore the driving relationship between the sports industry and local economic development and deconstruct the dynamic regulation mechanism of “Internet +” on the economic spillover of the sports industry. Empirical data collected from China’s 11 inter-provincial panel data from 2015–2019 were analyzed through the fixed-effects and threshold models. The study finds that the economic spillover of the sports industry has significantly promoted regional economic development, and the regulation effect of the Internet has complex non-linear characteristics. Only when Internet development exceeds a specific threshold can it develop a benign complementary mechanism with the sports industry. The impact of “Internet +” on the threshold regulation of the sports industry economic spillover has spatial and temporal differentiation characteristics in the three dimensions of Internet hardware level, Internet penetration rate, and Internet application value. The results of this study extend the current study, indicating that it is a practical choice for local governments to develop the economy through the sports industry. Provinces and cities should enhance the Internet penetration rate, expand Internet business applications, and upgrade Internet development to a specific point to maximize the drive of positive spillover. Regional heterogeneity requires differential regulation strategies and more concentration on the middle and western regions.</div

    Health-Promoting Lifestyle of Breast Cancer Patients and Family Members in a Chinese Genetic Counseling Clinic: A Cross-Sectional Study

    Background: Risk management strategies play a significant role in genetic counseling, which involves lifestyle modification with respect to nutrition and unhealthy living habits, enhanced screening imaging, endocrine therapy, and following the physician’s advice etc. This study aimed to describe the health-promoting lifestyle of breast cancer patients and their family members in a Chinese genetic counseling clinic, and to explore its various levels encompassing different socio-economic variables. Methods: This was a cross-sectional study. The participants in this study originated from a genetic counseling clinic of a cancer center in Shanghai, China. Two hundred and fifty nine patients conforming to the inclusion and exclusion criteria were screened from November 2019 to March 2022. Participants agreeing to participate were sent a questionnaire web-link with an invitation to finish this survey. Two questionnaires were included in the link, one referring to socio-economic information and the other referring to the health-promoting lifestyle. Chinese Health-promoting lifestyle profile-Ⅱ (HPLP-Ⅱ) was used to evaluate the health-promoting lifestyle. Results: One hundred and forty participants were finally included in this study. The mean scores for health-promoting lifestyle was 141.22 ± 19.77, and multiple liner regression revealed monthly family income to be a statistically significant predictor of health-promoting lifestyle (p < 0.05). In the six subscales, health responsibility got the highest score (26.43 ± 4.40), and nutrition received the lowest score (17.81 ± 4.73). Self-actualization was 25.84 ± 4.19, physical activity 24.02 ± 4.97, interpersonal relationship 22.21 ± 4.42, and stress management 24.91 ± 4.39. Conclusions: A representative level of health-promoting lifestyle of breast cancer patients and family members in a Chinese genetic counseling clinic were acquired. More education and intervention should be tailored to enhance and encourage health-promoting lifestyle behaviors in participants with low monthly family income. Additionally, developing nutritional curriculum and strengthening the publicity of nutritional popular science are priorities for future improvement measures
