陈晓红,易国栋,成璐璐

《中国工程科学》 2015年第17卷第1期页码 120-128

摘要：

随着信息获取变得越来越方便快捷，消费者策略行为在日常生活中变得越来越普遍。同时，产品的易腐蚀性使得时间敏感的消费者的选择更复杂。本文研究存在策略型消费者的易腐蚀性产品最优定价问题。垄断厂商在一定时期内销售有限个产品，消费者根据效用最大化原则选择自身的最优购买时机。本文分为不补充库存和补充库存两种情形。研究表明，厂商与消费者之间存在博弈均衡，厂商公布定价策略后，存在最优的阈值函数划分消费者结构。消费者的策略行为对厂商利润有重大影响，厂商可以根据市场需求状况和消费者时间敏感程度通过适当的库存和价格设定来减少消费者策略行为带来的损失。补充库存只有在市场需求较大的时候才优于不补充库存情形。

♮-convexity and its applications in operations

Xin CHEN

《工程管理前沿（英文）》 2017年第4卷第3期页码 283-294 doi: 10.15302/J-FEM-2017057

摘要： -convexity, one of the central concepts in discrete convex analysis, receives significant attentions in the operations literature in recent years as it provides a powerful tool to derive structures of optimal policies and allows for efficient computational procedures. In this paper, we present a survey of key properties of -convexity and some closely related results in lattice programming, several of which were developed recently and motivated by operations applications. As a new contribution to the literature, we establish the relationship between a notion called -differential monotonicity and -convexity. We then illustrate the techniques of applying -convexity through a detailed analysis of a perishable inventory model and a joint inventory and transshipment control model with random capacities.

《医学前沿（英文）》 2016年第10卷第1期页码 91-100 doi: 10.1007/s11684-016-0428-0

摘要：

Preventive medicine has been incorporated in the medical school curriculum, but its effectiveness and the factors that affect it are yet to be widely looked into in the context of Malaysia. We aimed to measure the familiarity with, perception about the importance to learn, and the ability to practice preventive medicine as well as its determinants among the medical students in Malaysia. Thus, a cross sectional study was conducted through an anonymous online survey among 387 randomly selected final year medical students of four large public medical schools in Malaysia from March to September 2014. Of the total sample, only 340 (response rate 87.8%) gave a written informed consent and took part in the survey. The familiarity of the sample with preventive medicine was measured in 19 preventive medicine areas, and their perception about the importance of preventive medicine and their ability to practice it were gauged on a Likert scale (low score indicates disagreement and high indicates agreement). Descriptive statistical analysis was performed, followed by logistic regression. The mean age of the respondents was 23.7 (SD 0.77) years, and 61.2% (n = 208) of them were females. Results showed that 22.9% of the sample (n= 78) had a low familiarity with preventive medicine, whereas 76.8% (n = 261) had a high familiarity. The study sample specified that among all the preventive medicine subjects, screening and control as well as smoking cessation and immunization are “extremely important to learn.” In univariable analysis, being a female, medical school, family size, and perception about the importance to learn preventive medicine were associated with the ability to practice it. In multivariable analysis, the perception towards the importance to learn preventive medicine was the only significant determinant: aOR (adjusted odds ratio) for those who “agreed” 17.28 (95% CI aOR 4.44 – 67.26, P<0.001) and for “strongly agreed” 35.87 (95% CI aOR 8.04 – 159.87, P<0.001). Considering these findings, the familiarity of medical students with preventive medicine should be increased. The perception about the importance to learn preventive medicine is a strong determinant for the ability to practice it.

《医学前沿（英文）》 2015年第9卷第2期页码 251-259 doi: 10.1007/s11684-015-0393-z

摘要：

Unhealthy behaviors of medical students influence their attitudes toward preventive counseling. The burden of chronic diseases is continually growing in developing countries, emphasizing the need for the increased role of general practitioners in preventive counseling. The objective of this study was to describe the effect of medical training on the risk profiles and attitudes of medical students toward preventive counseling in a Colombian university. Students in their first and fifth years of training were surveyed using the “Healthy Doctor= Healthy Patient” questionnaire to assess counseling attitudes; personal practices, such as risky drinking, smoking, inadequate nutrition, and non-compliance with physical activity recommendations; and the university environment. The association among these components was estimated, as well as the effect of the university environment. Risky drinking and smoking decreased from first to fifth year (59.3% vs. 37.1%, P = 0.021 and 31.5% vs. 25.9%, P = 0.51, respectively), whereas inadequate nutrition and non-compliance with physical activity recommendations increased. Physical activity (PA) was associated with positive counseling attitude (ORs: nutrition 7.6; alcohol 5.2; PA 10.6). Areas governed by institutional policies that are emphasized in the curriculum positively affected student practices. PA promoted preventive counseling and healthy lifestyles most effectively. Universities should therefore strengthen their preventive medicine curricula and modify social determinants.

摘要：

With the transformation of modern medicinal pattern, medical studies are confronted with methodological challenges. By analyzing two methodologies existing in the study of physical matter system and information system, the article points out that traditional Chinese medicine (TCM), especially the treatment based on syndrome differentiation, embodies information conception of methodological positions, while western medicine represents matter conception of methodological positions. It proposes a new way of thinking about combination of TCM and western medicine by combinating two kinds of methodological methods.

《医学前沿（英文）》 2008年第2卷第2期页码 143-146 doi: 10.1007/s11684-008-0027-9

摘要： Twenty-seven patients with severe colon trauma treated in the Shaoxing People’s Hospital from 1995 to 2006 were retrospectively analyzed. The patients with severe tunica muscularis injury were treated by medical glue combined with the greater omentum during operations. The initial result was encouraging. All patients were cured with no anastomotic leakage or abscess. Therefore, reasonable use of medical glue combined with the greater omentum can not only improve the curative rate but also reduces postoperative complications for patients with colon injury.

摘要： As a promising method in artificial intelligence, deep learning has been proven successful in several domains ranging from acoustics and images to natural language processing. With medical imaging becoming an important part of disease screening and diagnosis, deep learning-based approaches have emerged as powerful techniques in medical image areas. In this process, feature representations are learned directly and automatically from data, leading to remarkable breakthroughs in the medical field. Deep learning has been widely applied in medical imaging for improved image analysis. This paper reviews the major deep learning techniques in this time of rapid evolution and summarizes some of its key contributions and state-of-the-art outcomes. The topics include classification, detection, and segmentation tasks on medical image analysis with respect to pulmonary medical images, datasets, and benchmarks. A comprehensive overview of these methods implemented on various lung diseases consisting of pulmonary nodule diseases, pulmonary embolism, pneumonia, and interstitial lung disease is also provided. Lastly, the application of deep learning techniques to the medical image and an analysis of their future challenges and potential directions are discussed.

《机械工程前沿（英文）》 2011年第6卷第1期页码 40-44 doi: 10.1007/s11465-011-0204-4

摘要：

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.

WEI Xiaojuan, LIU Jing

《能源前沿（英文）》 2008年第2卷第1期页码 1-13 doi: 10.1007/s11708-008-0016-3

摘要： Implantable medical devices (IMDs) are critically requested for the survival of patients subject to certain serious diseases such as bradycardia, fibrillation, diabetes, and disability, etc. Appropriate working of an active implantable medical device (IMD) heavily relies on the continuous supply of electricity. In this sense, long-term powering and recharging of an IMD via a highly safe, efficient and convenient way is, therefore, extremely important in clinics. Several conventional batteries, such as lithium cell, nuclear cell and bio-fuel cell, etc., have been developed to power IMDs. Meanwhile, the recharge of IMD from outside of the human body is also under investigation. In this paper, some of the most typical IMD batteries are reviewed. Their advantages and disadvantages are compared. In addition, several emerging innovations to recharge or directly drive the implanted batteries, including electromagnetic energy transmission, piezoelectric power generation, thermoelectric devices, ultrasonic power motors, radio frequency recharging and optical recharging methods, etc., are also discussed. Some fundamental and practical issues thus involved are summarized, and future prospects in this area are made.

《医学前沿（英文）》 2016年第10卷第4期页码 473-480 doi: 10.1007/s11684-016-0479-

摘要：

Aiming to control rising medical expenditures and help improve China’s healthcare systems, this study examined whether a cap-based medical insurance scheme with shared financial interest between the insurance and healthcare providers is effective in containing hospitals’ C-section medical expenditures. We used 6547 caesarean delivery case records from a teaching tertiary-level general public hospital located in Wuxi, China (2004–2013), and used the Chow test to investigate the possibility of significant variation in mean medical expenditures for caesarean deliveries pre- and post-reform. We also used paired sample t-tests and linear regression models to compare the mean medical expenditures between insured and uninsured women undergoing caesarean delivery during the post-reform period. After the scheme’s implementation, medical expenditures for caesarean deliveries declined and the medical expenditures of women covered by the scheme were significantly lower than those of uninsured patients. These findings indicated the scheme’s effectiveness in minimizing caesarean delivery expenditures. The cap-based medical insurance scheme with shared financial interest between insurance and healthcare providers would likely steer healthcare providers’ behaviors in a more cost-effective direction.
