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.

Continuous amino-functionalized University of Oslo 66 membranes as efficacious polysulfide barriers for

《化学科学与工程前沿（英文）》 2023年第17卷第2期页码 194-205 doi: 10.1007/s11705-022-2206-7

摘要： The shuttle effect of soluble polysulfides is a serious problem impeding the development of lithium−sulfur batteries. Herein, continuous amino-functionalized University of Oslo 66 membranes supported on carbon nanotube films are proposed as ion-permselective interlayers that overcome these issues and show outstanding suppression of the polysulfide shuttle effect. The proposed membrane material has appropriately sized pores, and can act as ionic sieves and serve as barriers to polysulfides transport while allowing the passage of lithium ions during electrochemical cycles, thereby validly preventing the shuttling of polysulfides. Moreover, a fast catalytic conversion of polysulfides is also achieved with the as-developed interlayer. Therefore, lithium−sulfur batteries with this interlayer show a desirable initial capacity of 999.21 mAh·g^–1 at 1 C and a durable cyclic stability with a decay rate of only 0.04% per cycle over 300 cycles. Moreover, a high area capacity of 4.82 mAh·cm^–2 is also obtained even under increased sulfur loading (5.12 mg·cm^–2) and a lean-electrolyte condition (E/S = 4.8 μL·mg^–1).

Life cycle carbon emission assessment of a multi-purpose university building: A case study of Sri Lanka

Ramya KUMANAYAKE, Hanbin LUO

《工程管理前沿（英文）》 2018年第5卷第3期页码 381-393 doi: 10.15302/J-FEM-2018055

摘要：

Buildings are known to significantly affect the global carbon emissions throughout their life cycle. To mitigate carbon emissions, investigation of the current performance of buildings with regard to energy consumption and carbon emissions is necessary. This paper presents a process-based life cycle assessment methodology for assessing carbon emissions of buildings, using a multi-storey reinforced concrete building in a Sri Lankan university as a case study. The entire cradle-to-grave building life cycle was assessed and the life span of the building was assumed as 50 years. The results provide evidence of the significance of operation and material production stages, which contributed to the total carbon emissions by 63.22% and 31.59% respectively. Between them, the main structural materials, concrete and reinforcement steel made up 61.91% of the total carbon emitted at the material production stage. The life cycle carbon emissions of the building were found to be 31.81 kg·m⁻² CO₂ per year, which is comparable with the values obtained in similar studies found in the literature. In minimizing the life cycle carbon emissions, the importance of identifying control measures for both building operation and material production at the early design stage were emphasized. Although the other life cycle stages only contributed to about 5.19% of the life cycle carbon emissions, they should also receive attention when formulating control strategies. Some of the recommended strategies are introducing energy efficiency measures in building design and operation, using renewable energy for building operation and manufacturing of materials, identifying designs that can save mass material quantities, using alternative materials that are locally available in Sri Lanka and implementing material reuse and recycling. This study is one of the first to undertake a life cycle carbon emissions assessment for a building in the Sri Lankan context, with the hope of facilitating environmentally-friendly buildings and promoting sustainable construction practices in the country.

摘要： Reducing the frequency of engineering accidents is a “people’s responsibility.” Increased attention to engineering ethics is inevitable. Engineering ethics are a stance, attitude or outlook, not easily learned by lectures. This article explores the utility of student teamwork by applying the Theory of Planned Behavior and acknowledging the benefits of professional knowledge and professional ethics possessed by the professional teachers, under professional teacher guidance, in order to improve levels of engineering education ethics. There are 5 key points: ① team member recruitment standards; ② team size; ③ team name and motto; ④ team group activities; ⑤ extending the spirit into the post-graduate period.

摘要： As FlexRay communication protocol is extensively used in distributed real-time applications on vehicles, signal scheduling in FlexRay network becomes a critical issue to ensure the safe and efficient operation of time-critical applications. In this study, we propose a rectangle bin packing optimization approach to schedule communication signals with timing constraints into the FlexRay static segment at minimum bandwidth cost. The proposed approach, which is based on integer linear programming (ILP), supports both the slot assignment mechanisms provided by the latest version of the FlexRay specification, namely, the single sender slot multiplexing, and multiple sender slot multiplexing mechanisms. Extensive experiments on a synthetic and an automotive X-by-wire system case study demonstrate that the proposed approach has a well optimized performance.
