Taiwan has been developing clean energy and solar heating for hot water production is a mature technology. The subsidy program (2000-2016) for solar water heaters means that the cumulative area of solar collectors installed was approximately 2.52 million square meters at the end of 2016, in which more than 93% have been installed in the domestic sector. Industrial heat processes represent an area for solar thermal application. This study presents field measurements for solar water heaters installed for sterilization in dairy industry. Global solar radiation can be correlated with the system’s thermal efficiency reasonably well. As a pre-heating system, financial viability is validated.

The purpose of hierarchical medical system is to lead in terms of improving efficiency, differentiating healthcare services and promoting labor division by changing the healthcare seeking behavior. The purpose of this research aims to discuss the public awareness of hierarchical medical system in Taiwan for the reference of health policy makers. We obtained our research data using a questionnaire survey;the total number of qualified patients was 1340. This research finds that more subjects agreed to the hierarchical medical system and medical referral system, but many people still disagreed with changes to their healthcare seeking choices due to policy promotion. Subtle changes, therefore, are observed that imply a crisis in terms of the trust in healthcare. The healthcare seeking behavior will not change if there is a difference between the medical awareness of patients and policy implementation, and the government needs to be concerned with this result when making policies.

交叉参照是填补数据空白的重要方法,广泛应用于法规的合规中。除了单组分物质外,对复杂物质的交叉参照应用还需要额外的考虑。这种额外的考量和每个个案的复杂性对化学品制造商和监管机构都带来了独特的挑战性。在这个案例研究中,应用证据权重和交叉参照的方法,将几种复杂的石油衍生物质的数据推导到单一复杂碳氢化合物的目标物质,以填补欧盟REACH法规下生殖发育毒性的数据缺口。该案例已被欧盟监管机构接受。

Vaccination, one of the most effective strategies to prevent infectious diseases, is the administration of antigenic materials to stimulate an individual＇s immune system to develop adaptive immunity to a specific pathogen. Though it is so advantageous for diseases control and prevention, vaccines still have some limitations. Nanotechnology is an approach to prepare a novel biomedicine-vaccine with the vaccine consumption and side effects significantly decreased. Regulation is the most important criterion for the development of nanovaccines. All marketing products have to meet the requirement of regulation. The fast track designation potentially aids in the development and expedites the review of nanovaccines that show promises in an unmet medical need. Here, some successful nanovaccine products are introduced---Inflexal^（R） V, Epaxal^（R）, Gardasil^TM and Cervarix^TM have been widely used for the clinical applications, which are delivered in the form of either virosomes or virus-like particles. Vaccines based on nanotechnology may overcome their original disadvantages and lead to the development of painless, safer and more effective products. In this study, nanotechnology is shown to be a good strategy to make a perfect vaccination system through advanced skills and strict regulation requirements.

Patients with cancer are at high risk for thrombotic events,which are known collectively as Trousseau's syndrome. Herein,we report a 66-year-old male patient who was diagnosed with terminal stage gastric cancer and liver metastasis and who had an initial clinical presentation of upper gastrointestinal bleeding. Acute ischemia of the left lower leg that resulted in gangrenous changes occurred during admission. Subsequent angiography of the left lower limb was then performed. This procedure revealed arterial thrombosis of the left common iliac artery with extension to the external iliac artery,the left common iliac artery,the posterior tibial artery,and the peroneal artery,which were occluded by thrombi. Aspiration of the thrombi demonstrated that these were not tumor thrombi. The interesting aspect of our case was that the disease it presented as arterial thrombotic events,which may correlate with gastric adenocarcinoma. In summary,we suggested that the unexplained thrombotic events might be one of the initial presentations of occult malignancy and that thromboprophylaxis should always be considered.

毁灭泰泽球虫的小配子生殖发生在小肠上皮细胞内由单层膜围成的带虫空泡中。其细胞核的分裂过程与裂殖生殖时期的相似,但小配子体的细胞核缺少核仁,染色质在核的浅层聚集成致密的斑块。在小配子的形成过程中,核附近的中心粒转变为基粒,其中央微管消失。随后,两根鞭毛从基粒长出,突入带虫空泡。细胞核的致密部分逐渐地进入小配子体的表面突起,并最终发育为小配子的细胞核;而核的疏浅部分则留在小配子体的细胞质中,成为残体的成份。成熟的小配子拥有两根纤长的鞭毛和香蕉形的身体,体内含有长形的细胞核及在其尖端嵌入的线粒体,一组微管(4+1+1)自基粒附近向体后延伸,但仅约3根微管抵达身体的末端。

UVCB物质是化学结构未知、组分可变、复杂的反应产物或生物材料物质。石油类UVCB是其中典型的代表。虽然其主要成分是碳氢类化合物,但由于异构的多样性,每种成分的精确结构和含量是不确定的。在流程上,这类物质的交叉参照和常规物质遵循类似的步骤。但是由于其特有的复杂特性,这类物质的交叉参照常常需要额外的考虑,包括如何界定相似性、如何寻找类似物、如何论证交叉参照的可行性以及成分间的潜在相互作用等。作为此次交叉参照专题的系列文章,本文旨在帮助理解石油类UVCB类物质进行交叉参照填补数据缺口时面临的关键挑战。
