Hubungan Pengetahuan dan Sikap Terhadap Kecelakaan Kerja Tertusuk Jarum Suntik pada Perawat di Rumah Sakit Anugerah Tomohon

Kecelakaan kerja berupa luka tusuk benda tajam merupakan masalah kesehatan kerja yang umum dihadapi oleh tenaga kesehatan khususnya perawat. Luka tertusuk jarum berisiko dapat mengakibatkan  penyakit menular seperti HIV, Hepatitis B dan penyakit lainnya. Maka diperlukan pelatihan dan pengawasan serta perkembangan ilmu kesehatan dalam penanganan kejadian kecelakaan kerja tertusuk jarum suntik. Penelitian ini bertujuan untuk mengetahui hubungan Pengetahuan dan sikap terhadap kecelakaan kerja tertusuk jarum suntik pada perawat yang dilaksanakan di Rumah sakit anugerah tomohon pada bulannovember-desember 2021. Metode penelitian ini deskriptif kuantitatif dengan desain penelitian cross sectional. Penelitian ini mengunakan Sampel sebanyak 104 responden dengan menggunakan teknik pengambilan sampel yaitu total sampling. Instrumen dalam penelitian ini menggunakan kuisioner. Pada penelitian ini ditemukan tidak ada hubungan yang signifikan antara pengetahuan terhadap kecelakaan kerja tertusuk jarum suntik dengan nilai p 0,132. Kemudian terdapat hubungan antara sikap terhadap kecelakaan kerja tertusuk jarum suntik dengan nilai p 0,01. Kata Kunci : luka tusuk jarum suntik, pengetahuan, sikap ABSTRACTWork accidents in the form of sharp objects are a health problem faced by health workers, especially nurses. Needle stick wounds are at risk of causing infectious diseases such as HIV, Hepatitis B and other diseases. Therefore, training and supervision are needed as well as the development of health sciences in handling the incidence of needle stick accidents. This study aims to determine the relationship between knowledge and attitudes towards needle stick injuries in nurses at the Grace Tomohon Hospital in November-December 2021. The research method is quantitative descriptive with a cross sectional research design. This study used a sample of 104 respondents by using a sampling technique that is total sampling. The instrument in this study used a questionnaire. In this study, there was no significant relationship between knowledge and work accidents with needle sticks, which was found with a p value of 0.132. Then there is a relationship between attitudes towards needle stick accidents with p 0.01. Keywords: Needle stick injury, knowledge, attitud

Experimental and theoretical investigations of the NiII complex with N-phosphorylated thiourea iPrNHC(S)NHP(O)(OPh)2

The N-phosphorylated thiourea iPrNHC(S)NHP(O)(OPh)2 (HL) has been synthesized by the reaction of iPrNH2 and (PhO) 2P(O)NCS. Recrystallization of HL from aqueous acetone leads to [iPrNH3]+[P(O)2(OPh)2]- in a quantitative yield. Reaction of the deprotonated HL with NiCl2 leads to violet [NiL2] crystals with a 1,3-N,S-coordination mode of the ligands. Static DFT and ab initio molecular dynamics studies indicated that [NiL2] is stabilized predominantly by intramolecular N-H⋯OP hydrogen bonding and dynamically by secondary CPh-H⋯S interactions. All compounds have been characterized by IR, diffuse reflectance, UV-vis and NMR spectroscopy, single crystal X-ray diffraction analysis and elemental analysis. Thermal properties investigated in an air atmosphere by means of TGA revealed a residue corresponding to NiPS3. © 2013 The Royal Society of Chemistry

Polymorphism driven optical properties of an anil dye

Red crystals of N,N′-bisIJ3-methoxysalicylidene)-1,5-diiminonaphthalene were obtained after Schiff base condensation in ethanol. Recrystallization from acetone afforded yellow crystals, a process which is reversible and reproducible. Single crystal X-ray diffraction evidences two polymorphs differing in their space group and dihedral angle between aromatic moieties. DFT periodic calculations further confirmed the existence of two minima on the potential energy surface corresponding to red and yellow crystals. The red polymorph irreversibly (monotropically) transforms at 165–190 °C into the yellow one with a 3% increase of the unit cell volume, as shown by X-ray powder diffraction and periodic DFT calculations. Both polymorphs are thermochromic but only the red one displays photochromism upon irradiation at λ = 365 nm, which is reversible and exhibits a relatively slow thermal relaxation. A temperature induced cis/trans-keto equilibrium is for the first time identified for an N-salicylidene aniline derivative. Static DFT molecular and periodic calculations as well as ab initio Born–Oppenheimer dynamics simulations were performed to characterize the stability of both polymorphs and to determine the relative populations of the enol/cis-keto/trans-keto isomers at various temperatures
