Microstructure control of Fe catalyst films for the growth of multiwalled carbon nanotube arrays
Guo-an Cheng,Hua-ping Liu,Rui-ting Zheng,Yong Zhao,Chang-lin Liang 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.-
Fe catalyst films were deposited on silicon substrates by using a metal vapor vacuum arc (MEVVA) ion deposition system for the growth of aligned multiwalled carbon nanotubes. The effects of deposition angle and film thickness on the morphologies of catalyst films before and after thermal treatment were investigated. The results show that the uniformities of both 5-nm and 10-nm films are enhanced as the deposition angle decreases. With increase from 5 nm to 10 nm, the surface uniformities of pristine films prepared at higher deposition angles (60˚ and 90˚) are increased, while that of the films produced at 30˚ deposition angle is slightly decreased. The uniformity of Fe catalyst particle sizes after thermal treatment on the whole, clearly decreases as the thickness is increased from 5 nm to 10 nm in the case of the same deposition angle. 5-nm films deposited at 30˚ deposition angle show the most uniform features before and after thermal treatment and can be used for the synthesis of high-quality carbon nanotube arrays.

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Crohn`s disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

Aim(s): Design Thinking is a human-centered problem-solving solution. It seeks innovative solutions for different issues by starting from human needs. The process includes empathizing, defining, ideating, prototyping, and testing. Innovation is a new trend for nursing education and talent training, but nursing-related research that combines design thinking with innovative research and development is lacking. In this study, cross-disciplinary instructors used design thinking to lead a team of nursing students in innovating on a Pre-loaded Diluent and Medication Syringe. The completed pilot test provides implementation and research directions for innovation education. Method(s): The researchers created 15 questions regarding ease of operation, safe use, environmental friendliness, and economic benefits for their self-developed Pre-loaded Diluent and Medication Syringe. The research team then demonstrated the device to 40 invited nursing students with registered nurse licenses, who were then asked to complete the questionnaire, thus allowing score-based comparisons between this innovative syringe and traditional syringes used in drug administration. The data was analyzed using descriptive and inferential statistics. Result(s): The results of the research showed that there was no significant difference on the “applicable to all types of wards” question for ease of operation, but the other 14 items all showed significant differences (P<.05). The reason for that insignificant difference may be due to unmet needs for micro-administration of special drugs and reuse of pediatric surplus; this prompted the research team to carry out develop on a Drug-mixing Syringe Feasible for Multiple Administrations. Conclusion(s): Based on the evaluation results, the research team developed a syringe more optimized to meet clinical needs. The study provides cross-disciplinary guidance to students in the process of nursing innovation, and narrows research gaps in related fields.
