Điều dưỡng được phỏng vấn bằng một bộ câu hỏi trước và sau đào tạo để khai thác các đặc điểm về nhân khẩu học, kinh nghiệm công tác, kiến thức chăm sóc người bệnh đặt buồng tiêm truyền, các biến chứng liên quan đến buồng tiêm truyền. Kết quả: tuổi trung bình 29,9 ± 5,4 tuổi, 73% nữ, 27% nam. 60,4% điều dưỡng có thời gian công tác dưới 5 năm. Nhóm điều dưỡng trình độ đại học và sau đại học chiếm tỉ lệ cao 69,4%, không có điều dưỡng trung cấp. Đa số điều dưỡng chưa được đào tạo về chăm sóc bệnh nhân có buồng tiêm truyền trước đó (77,5%). Điểm trung bình kiến thức của điều dưỡng trước đào tạo là 14,45 ± 3,77, sau đào tạo là 20,91 ± 3,74, sự khác biệt có ý nghĩa thống kê với p < 0,001. Có mối liên quan giữa nhóm tuổi, giới tính, trình độ, khoa công tác, thời gian công tác, và kinh nghiệm chăm sóc buồng truyền với điểm tr...

Kết luận: hầu hết các bước chuẩn bị người bệnh trước phẫu thuật được thực hiện khá tốt. Tuy nhiên, còn một số bước được thực hiện chưa tốt là: tìm hiểu tâm lý người bệnh, hướng dẫn người bệnh vệ sinh cá nhân, hoàn thiện giấy cam kết thực hiện phẫu thuật/thủ thuật/gây mê hồi sức, xác nhận bác sĩ đã đánh dấu vị trí phẫu thuật, đo lại dấu hiệu sinh tồn và vận chuyển người bệnh đi phẫu thuật.

It is a new record for the orchid flora of Vietnam. Previously this species was recorded in Hong Kong and Hainan (South-East China). Living specimens were collected in Quang Nam province and flowering successfully in a private garden in Da Lat city, Lam Dong province. Based on morphological characters, B. tseanum is very close to B. lepidum in the plant habit, shape, and color scheme of flowers, but can be distinguished by broadly ovate dorsal sepal, longer lateral sepals, narrow petals with shortly caudate apex, size of stelidia and column wing shape. The description of Vietnamese plants is presented, accompanied by the analytical plate and taxonomic notes.

Short description, data on habitat, phenology, distribution, illustrations and identification key for all species are included. Campanulorchis globifera was firstly recorded for the orchid flora of Cambodia and C. thao firstly recorded in Laos.

This limitation is a consequence of the continuum mechanics based governing equations which are cast as partial-differential equations (PDEs) that are not well-defined at cracks or singularities. Recently, a new non-local formulation of continuum mechanics named a Peridynamics (PD) theory has been proposed, which replaces PDEs with equivalent integrodifferential equations. The framework results in governing equations that do not require spatial derivatives and allows for treatment of solid-continua containing cracks/discontinuities in a unified meshless manner. In this talk, we will discuss recent advances in meshless Peridynamics-based crack/damage modeling and discuss the novel computationa...

Brachyantha) discovered in Da Lat Plateau, Lam Dong Province (southern Vietnam) is described here. This new species is close to B. pumilio but clearly differs in densely crowded pseudobulbs and their shape, shorter inflorescence, lateral sepals forming a narrow acute tube slightly flattened at the base, lip without median keel, and longer stelidia. In addition, a new national record, B. seidenfadenii, from the same section is also reported from the first time from North Vietnam.

Since housing price is strongly correlated to other factors such as location, area, population, it requires other information apart from HPI to predict individual housing price. There has been a considerably large number of papers adopting traditional machine learning approaches to predict housing prices accurately, but they rarely concern about the performance of individual models and neglect the less popular yet complex models. As a result, to explore various impacts of features on prediction methods, this paper will apply both traditional and advanced machine learning approaches to investigate the difference among several advanced models. This paper will also comprehensively validate multiple techniques in model implementation on regression and provide an optimistic result for housing price prediction.

The compounds are also useful for the treatment of depression and anxiety. [Formula 1]

The antiviral effectiveness of the guanosine nucleosides was evaluated by converting them to the corresponding 5-O-triphosphates (compounds 38-44) and testing their biochemical inhibitory activity against the wild-type NS5B polymerase.

As an example, (1R,2S)-9 demonstrated not only potent in vitro SST3 agonist activity but also in vivo SST3 agonist activity in a mouse oral glucose tolerance test (OGTT). These agonists may be useful reagents for studying the physiological roles of the SST3 receptor and may potentially be useful as therapeutic agents.

A series of cyclic b-amino acids (b-aa) was studied as VLA-4 antagonists. Binding affinity was highly dependent on the dihedral angle (/) between the amino and the carboxyl termini of the b-aa. Compound 5m where the b-aa is embedded in a bicycle possesses the most preferred / (120°). It is a potent and bioavailable VLA-4 antagonist (VCAM-Ig a4b1 IC 50 = 54 nM, rat po F = 49%).

They were variably more potent than the corresponding amide analogues. The most potent representative 22 had good pharmacokinetic and brain levels, but was modestly active in blocking CB1R agonist-mediated hypothermia.
