Anesthetic management for combined mitral valve replacement and aortic valve repair in a patient with osteogenesis imperfecta
Huang Jiapeng,Dinh Michelle,Kuchle Nicholas,Zhou Jing
Annals of Cardiac Anaesthesia , 2011,
Abstract: Osteogenesis imperfecta is a rare disorder of connective tissues and presents multiple challenges, including difficult airway, hyperthermia, coagulopathy and respiratory dysfunction, for anesthesiologists, especially during cardiac surgery. We present anesthetic management of a patient with osteogenesis impertecta during double valve surgery. Dexmedetomidine infusion minimized the risks of malignant hyperthermia. Glidescope and in-line stabilization facilitated endotracheal intubation and protected his oral structures and cervical spine. Transesophageal echocardiography (TEE) diagnosed a flail A3 segment and redundant left coronary cusp causing mitral and aortic regurgitation. The mitral valve was replaced and the aortic valve repaired. Coagulopathy was corrected according to comprehensive coagulation analysis. Glidescope, dexmedetomidine, coagulation analysis and TEE could facilitate anesthetic management in these patients.
Proposal of Cooperative Communication to Enhance Accuracy of Wireless Control Systems  [PDF]
Nguyen Cong Dinh
Communications and Network (CN) , 2019, DOI: 10.4236/cn.2019.112005
Abstract: Control systems are being changed from wired to wireless communications because of flexibility, mobility and extensibility of wireless communication systems; however the reliability of wireless communications is suspected. In this paper, we propose cooperative communication scheme for wireless control systems which consist of a controller and multiple machines; these machines cooperatively work in a group and for the same duty. In the proposed method, the controller can communicate with machines directly or via other machines, whereas in the conventional method, the controller only communicates with machines directly. The simple 2-link arm plant is used to evaluate our proposed system, and the simulation results indicate that the proposed method is more accurate, and more stable than the conventional method.
Inconsistency and Accuracy of Heuristics with A* Search
Hang Dinh,Hieu Dinh
Computer Science , 2013,
Abstract: Many studies in heuristic search suggest that the accuracy of the heuristic used has a positive impact on improving the performance of the search. In another direction, historical research perceives that the performance of heuristic search algorithms, such as A* and IDA*, can be improved by requiring the heuristics to be consistent -- a property satisfied by any perfect heuristic. However, a few recent studies show that inconsistent heuristics can also be used to achieve a large improvement in these heuristic search algorithms. These results leave us a natural question: which property of heuristics, accuracy or consistency/inconsistency, should we focus on when building heuristics? While there are studies on the heuristic accuracy with the assumption of consistency, no studies on both the inconsistency and the accuracy of heuristics are known to our knowledge. In this study, we investigate the relationship between the inconsistency and the accuracy of heuristics with A* search. Our analytical result reveals a correlation between these two properties. We then run experiments on the domain for the Knapsack problem with a family of practical heuristics. Our empirical results show that in many cases, the more accurate heuristics also have higher level of inconsistency and result in fewer node expansions by A*.
Preparation and Characterization of La0.67–x Li3x TiO3 Solid-State Electrolyte Used for Electrochromic Mirrors  [PDF]
Le Dinh Trong, Nguyen Nang Dinh, Do Hong Thanh
Materials Sciences and Applications (MSA) , 2016, DOI: 10.4236/msa.2016.711056
Abstract: With the aim of producing all-solid-state electrochromic mirrors, La0.67xLi3xTiO3 (LLTO) and the WO3 were prepared by electron beam deposition. The LLTO (with x = 0.11) powder was synthesized by thermally ball-grinding method and the Li+ ionic conductivity of the LLTO ceramic targets was found to be of ca. 3.25 × 103 S/cm. Using LLTO targets for e-beam evaporation, 300 nm-thick films with the Li+ ionic conductivity of 5.50 × 105 S/cm were deposited. Combining LLTO films with WO3/ITO and LiMn2O4 layers, all-solid-state electrochromic mirrors with a laminar structure of Al/LiMn2O4/LLTO/WO3/ITO were prepared. The reversible reflectance of the mirrors was well controlled by applying polarized potentials onto the ITO electrode. The obtained results suggest useful applications for electrochromic windows working as a smart reflectance mirror that can be used for auto rear-view mirrors.
Health Promotion in Cardiac Rehabilitation Patients through the Use of a High-Intensity Interval Training Protocol  [PDF]
Michelle Tinkham
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.410059
Abstract: According to the American Heart Association’s (AHA) recent statistical update, over 2150 Americans die each day from cardiovascular disease (CVD), which equals approximately 1 death every 40 seconds; many of which were under the age of 65 years old [1]. In 2009, 386,324 people, 1 in 6 Americans, died as a result of coronary artery disease (CAD) alone [1]. They also estimate 150,000 people have “silent” heart attacks each year [1]. Even though the number of cardiovascular disease deaths has declined in the last 10 years, they still accounted for 32.3% of American deaths [1]. As a result, the AHA updated their 2020 goals to improve the nation’s cardiovascular health by 20% [1]. One of these methods is through the use of cardiac rehabilitation. Cardiac rehabilitation (CR) is a health promotion strategy to help return cardiac patients to their previous level of functioning, increase health, decrease comorbidities and promote education and lifestyle change. For select patients, another alternative exercise plan may exist to gain even better results. High intensity interval training (HIIT) has shown positive training results for athletes and many studies show that it may also be an effective exercise modality for many cardiac patients instead of the traditional circuit training method. This article will review current literature on the effects of HIIT on CR patients as well as a sample HIIT protocol for instituting this treatment with appropriate patients.
Emotionally Competent Behaviors and Nurse Bullying: Is There a Direct Link?  [PDF]
Michelle Doas
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.51008
Abstract: An abundance of literature spanning many years depicts the devastating effects of nurse bullying within the profession. The evidence suggests that bullying in general is a deliberate act aimed at another person. Conceptualizing nurse bullying appears to be a key ingredient in creating both awareness and preventative strategies. Emotional competence includes a set of behaviors which are unique to each individual. These behaviors according to Goldman (1995) include, but are not limited to emotional self-assessment, accurate self-assurance, self-confidence, emotional self-control, and empathy. The majority of researchers agree that emotionally competent behaviors are impacted by both positive and negative interactions and experiences. Thus, it is hypothesized that emotionally competent behaviors are continually cultivated throughout one’s life based upon lived experiences. This article assesses direct relationships between implementation of emotionally competent behaviors as a means of combatting nurse bullying within the profession. Creating awareness of these two areas can be initial steps in cultivating the needed tools and supportive interventions to assist nurses from novice to expert to professionally mentor and role model for generations to come.
Are We Losing the Art of Actively Listening to Our Patients? Connecting the Art of Active Listening with Emotionally Competent Behaviors  [PDF]
Michelle Doas
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.56060
Abstract: Active listening is an essential communication technique that requires the listener to focus and provide feedback on what is heard. The ability to listen actively demonstrates sincerity, and assumes that nothing is being shrugged or taken for granted. As a result, active listeners strive to improve professional and personal relationships, decrease misinterpretation of information, strengthen compliance, and foster understanding. Likewise, active listening can foster trust, mutual respect, and patient compliance. This paper will explore vital connections between active listening and displaying emotionally competent behaviors. Additionally, analysis of a case study as a means of strengthening these connections while improving patient outcomes will be assessed.
FDI of Vietnam; Two-Way Linkages between FDI and GDP, Competition among Provinces and Effects of Laws  [PDF]
Nguyen Dinh Chien, Kezhong Zhang
iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.42018
Abstract: This study focuses on problems related to foreign direct investment (FDI) in the North Central Area and South Central Coast of Vietnam in the period from 2000 to 2010, they consist of bidirectional relationship between foreign direct investment and economic growth (GDP), competition among provinces and effects of laws in attracting FDI. By using panel data and Ordinary Least Square (OLS) Method. Empirical analysis results found that: 1) There is a strong bidirectional relationship between FDI and GDP in this area of Vietnam. Both FDI and GDP also contributed significantly and positively in explaining each other in the provinces which was extremely difficult socio-economic conditions, however this is especially accurate in provinces having better conditions such as Da Nang city; 2) There is no strong competition between provinces in attracting FDI, provinces having better governance in economics attracted less registered FDI; 3) Ability to access information and infrastructure quality of provinces affects significantly and positively to attract FDI in this region; 4) After promulgating Common Investment Law as well as Unified Enterprises Law in 2005 and Vietnam joined the World Trade Organization (WTO) in 2007, the amount of registered FDI capital has increased rapidly in provinces of North Central Region and South Central Coast—Vietnam.

La littérature franco-vietnamienne : une réponse au colonialisme
Kathy Dinh
Voix Plurielles , 2011,
Abstract: Dans cet article, je me propose d’examiner comment la langue fran aise a été utilisée par les Fran ais pour faciliter des projets impériaux, mais aussi par des écrivaines vietnamiennes comme réponse au colonialisme fran ais. De plus, j’examinerai ce qu’implique le fait d’écrire dans une langue qui n’est pas la sienne – notamment dans la langue du colonisateur. Enfin, je discuterai l’importance de la langue, à savoir son emploi et son impact sur la culture et comment elle nous permet de comprendre la formation de l’identité du colonisé.
