Abstract

An experimental study has been carried out to measure the sensitive emission lines intensities of several metal samples (copper, zinc, silver, gold, gallium, nickel, silicone and iron) using laser ablation technique conducted in low pressure surrounding gas by means of Laser Induced Shock Wave Plasma Spectroscopy (LISPS) and in atmospheric pressure region using Laser Induced Breakdown Spectroscopy (LIBS). In both cases the Nd-YAG laser was operated at its fundamental wavelength of 1.064 nm with pulse duration of 8 ns and its intensity tightly focused on the metal samples in helium or air as an ambient gas. The laser energy was fixed at approximately 100 mJ using a set of neutral density filters placed tilted in front of the laser output window. The result of the intensity measurements showed a good agreement which those obtained using arc discharge technique as shown in Massachusetts Institute of Technology Wavelength Table. Further evaluation of these results on the basis of standard deviation leads to the conclusion that LISPS is more favorable for quantitative analysis compared to LIBS. It was further shown that replacing air by helium gas at low pressure improve to some extent the LISPS reproducibility and sensitivity.

Abstract

ABSTRAK Koordinasi keperawatan didasarkan pada layanan kesehatan yang berkualitas, dapat menjadi kunci untuk memperbaiki pengalaman perawatan individu, memperbaiki kesehatan masyarakat, dan mengurangi biaya perawatan bagi masyarakat. Penelitian ini menggunakan Systematic review terhadap beberapa study literature. Artikel dicari melalui penelusuran Ebscohost dengan menggunakan  CINAHL Complete, MEDLINE,  MEDLINE Complete periode tahun 2009 sampai 2017, didapatkan  29 artikel. Penelusuran dengan Proquest terdapat 537 artikel pada periode 2010-2018. Penelusuran dengan Scopus ditemukan 20 artikel pada periode 2001?2017, penelusuran dengan Google Scholar terdapat 16.800 artikel. Koordinasi keperawatan berfokus pada pasien (patient centre care) didasarkan pada tujuan reformasi keperawatan untuk meningkatkan kualitas keperawatan bagi individu dan masyarakat melalui penggunaan sumber daya yang efisien dan efektif. Peningkatan kompleksitas keperawatan, meningkatnya jumlah pasien dengan penyakit kronis, dan biaya perawatan kesehatan yang meningkat akan meningkatkan kebutuhan akan integrasi perawatan yang lebih baik tanpa peningkatan pengeluaran. Perawat preoperatif dalam  melakukan evaluasi kegiatan dan hasil  koordinasi koordinasi keperawatan dengan para pemberi asuhan lain yang berfokus pada pelayanan pasien, dengan  mengimplementasikan Care Coordination Measurement Tool (CCMT) pada pasien pre operatif.   Kata kunci : Koordinasi, keperawatan, pasien preoperative   EFFECTIVE NURSING COORDINATION FOR PREOPERATIVE PATIENTS   ABSTRACT Nursing coordination is based on quality healthcare, can be key to improving individual care experiences, improving public health, and reducing community care costs. This research used a systematic review of several study literature. The Articles has been searched through Ebscohost search using CINAHL Complete, MEDLINE, MEDLINE Complete period of  2009 to 2017, got 29 articles. Searched with Proquest period 2010-2018, there are found 537 articles. Search with Scopus found 20 articles to the period 2001-2017, search with Google Scholar there are 16,800 articles. Patient care coordination is based on the objectives of health care reform to improve the quality of care for individuals and populations through the efficient and effective use of resources. Increased maintenance complexity, increased number of patients with chronic disease, and increased health care costs will increase the need for better integration of care without increased spending. Preoperative nurses evaluate the activities and outcomes of coordinating nursing care coordination with other caregivers which  focus on patient care, by implementing the Care Coordination Measurement Tool (CCMT) in preoperative patients.   Keywords:  Nursing, coordination, preoperative, patient.

Abstract

Kegiatan koordinasi perawatan perioperatif  meliputi kegiatan pelayanan perawatan fase pre, intra dan post operatif. Beberapa kesalahan dalam menyiapkan pasien untuk diprogramkan operasi elektif dapat menyebabkan  masa lama rawat pasien  memanjang, readmissions berulang, menurunkan kualitas hidup, mengurangi  keselamatan dan kepuasan pasien dan peningkatan biaya. Situasi tersebut memerlukan upaya koordinasi perawatan yang berpusat pada pasien. Penelitian yang digunakan adalah kualitatif diskriptif, dengan analisa data metoda Colaizzi. Sebanyak lima partisipan perawat perioperatif dengan masa kerja lebih dari 3 tahun sebagai narasumber penelitian dengan kriteria tiga perawat ruang rawat inap bedah (katim, penanggung jawab shif dan perawat pelaksana), satu perawat kepala ruang bedah sentral dan satu perawat pelaksana kamar bedah serta satu partisipan sebagai triangulasi sumber yang merupakan dokter spesialis bedah mulut dan selaku kepala instalasi bedah sentral. Hasil didapatkan enam tema yaitu:keterlibatan pasien dan keluarga dalam pengelolaan layanan kesehatan sejak awal masuk rumah sakit, mekanisme penjadualan program operasi elektif, pengkajian pasien sebelum operasi, optimalisasi kelayakan kondisi kesehatan pasien,  metode koordinasi yang dilakukan oleh perawat  serta keadaan atau situasi yang membutuhkan koordinasi dengan berbagai profesional pemberi asuhan, pasien dan keluarga. Perawat dalam melaksanakan koordinasi perawatan menemukan hambatan atau tantangan dalam mensukseskan koordinasi perawatan yang dilakukan.Perawat dalam melakukan fungsi koordinasi perawatan, berfungsi sebagai care coordinator bukan hanya sebagai perawat pelaksana atau ketua tim. Kata kunci : koordinasi perawatan, perioperatif, perawat THE IMPLEMENTATION OF PERIOPERATIVE PATIENT CARE COORDINATION BY NURSES ABSTRACT Perioperative care coordination activities include pre, intra and post operative care service activities. Some errors in preparing patients for elective surgery programs can cause prolonged hospitalization, repeated readmissions, reduced quality of life, reduced patient safety and satisfaction and increased costs. This situation requires coordinating efforts for patient-centered care. The research used is descriptive qualitative, with Colaizzi method data analysis. Five perioperative nurse participants with a working period of more than 3 years as research sources with the criteria of three nurses inpatient surgery (Katim, person in charge of shif and executive nurse), one head nurse in the operating room and one nurse in the operating room and one participant as a participant as a nurse triangulation of sources who are oral surgeons and as the head of the central surgical installation. The Results obtained six themes, namely: involvement of patients and families in the management of health services from the beginning of the hospital admission, scheduling mechanisms for elective surgery programs, assessment of patients before surgery, optimization of the feasibility of the patient's health conditions, methods of coordination performed by nurses and circumstances or situations that require coordination with various care professionals, patients and families. Nurses in implementing care coordination find obstacles or challenges in the success of the coordination of care performed. Nurses in performing the care coordination function, functions as a care coordinator not just as an executive nurse or team leader. Keywords: care coordination, perioperative, nurse

Abstract

The Study on Fluorescence Characteristics of Chlorella spp: pH Influence on Culture. Experiments for measuring the fluorescence characteristics of Chlorella spp. by using high stability and high repetition rate nitrogen laser of energy 5 mJ with pulse duration of 5 ns have been carried out. The results show that for a cell concentration range from 2,625 cells/ml up to 2,769,000 cells/ml, the fluorescence intensities at pada λ = 687 nm have a linear relationship with the cell concentration. It has been also found that for a 7 days old chlorella culture, the pH variation at the starting culture influenced the cell concentration.
