EVALUASI KINERJA PELAYANAN INFRASTRUKTUR TERMINAL PASAR BARU KABUPATEN HALMAHERA SELATAN
Perkembangan Kabupaten Halmahera Selatan yang sangat pesat di iringi dengan pertumbuhan penduduk, ekonomi, sosial dan budaya yang sangat pesat pula tentu akan menyebabkan berbagai masalah dalam bidang transportasi yang harus segera di atasi dan juga dapat menimbulkan tuntutan untuk menambah kualitas dan kuantitas sistem transportasi yang meliputi berbagai fasilitas, yang salah satunya adalah fasilitas moda angkutan darat, yaitu terminal angkutan umum pasar baru. Terminal yang resmikan pada tahun 2005 ini melayani trayek arah barat yaitu pusat kota (Labuha), arah Timur yaitu jalur trayek yang melayani masyarakat Bacan tengah sampai dengan Bacan timur yaitu pelabuhan Babang, dan untuk pada bagian selatan melayani pelabuhan Kupal dan serta masyarakat bagian selatan. Namun proses sistem transportasi yang berlangsung tidak efektif sehingga pergerakan transportasi banyak berlangsung di luar terminal, sehingga mengakibatkan kemacetan dan lain-lain. Penelitian ini diawali dengan penyebaran kuesioner ke pihak penyedia dan pengguna jasa yang beraktifitas di terminal Pasar Baru. Analisis data dalam penelitian ini dilakukan dengan evaluasi tingkat ketersediaan kinerja insfrastruktur transportasi khususnya di Terminal angkutan umum Pasar Baru. Untuk menentukan tingkat kesediaan infrastruktur transportasi pada lokasi itu, maka di tetapkan suatu indikator dengan memberi pembobotan terhadap masing-masing kategori dengan menggunakan skala Likert dari masing-masing atribut pelayanan menurut penilaian/persepsi responden. Hasil yang diperoleh yaitu kinerja fungsi dari Infrastruktur di Terminal Pasar Baru Kabupaten Halmahera Selatan secara keseluruhan berdasarkan persepsi responden masuk kategori Kinerja Kurang baik, dengan nilai persentase 48,98 %. Faktor-faktor yang mempengaruhi kinerja Terminal Pasar Baru Kabupaten Halmahera selatan yang fungsi operasional menjadi prioritas utama untuk di tingkatkan oleh pihak penyedia jasa terdiri dari variabel wujud nyata, keandalan, keresposifan, daya tangkap, dan Jaminan
Electrically conductive nanomaterials for cardiac tissue engineering
Β© 2019 Elsevier B.V. Patient deaths resulting from cardiovascular diseases are increasing across the globe, posing the greatest risk to patients in developed countries. Myocardial infarction, as a result of inadequate blood flow to the myocardium, results in irreversible loss of cardiomyocytes which can lead to heart failure. A sequela of myocardial infarction is scar formation that can alter the normal myocardial architecture and result in arrhythmias. Over the past decade, a myriad of tissue engineering approaches has been developed to fabricate engineered scaffolds for repairing cardiac tissue. This paper highlights the recent application of electrically conductive nanomaterials (carbon and gold-based nanomaterials, and electroactive polymers) to the development of scaffolds for cardiac tissue engineering. Moreover, this work summarizes the effects of these nanomaterials on cardiac cell behavior such as proliferation and migration, as well as cardiomyogenic differentiation in stem cells

Pulsed radiofrequency treatment in interventional pain management: mechanisms and potential indicationsβa review
Item does not contain fulltextBACKGROUND: The objective of this review is to evaluate the efficacy of Pulsed Radiofrequency (PRF) treatment in chronic pain management in randomized clinical trials (RCTs) and well-designed observational studies. The physics, mechanisms of action, and biological effects are discussed to provide the scientific basis for this promising modality. METHODS: We systematically searched for clinical studies on PRF. We searched the MEDLINE (PubMed) and EMBASE database, using the free text terms: pulsed radiofrequency, radio frequency, radiation, isothermal radiofrequency, and combination of these. We classified the information in two tables, one focusing only on RCTs, and another, containing prospective studies. Date of last electronic search was 30 May 2010. The methodological quality of the presented reports was scored using the original criteria proposed by Jadad et al. FINDINGS: We found six RCTs that evaluated the efficacy of PRF, one against corticosteroid injection, one against sham intervention, and the rest against conventional RF thermocoagulation. Two trials were conducted in patients with lower back pain due to lumbar zygapophyseal joint pain, one in cervical radicular pain, one in lumbosacral radicular pain, one in trigeminal neuralgia, and another in chronic shoulder pain. CONCLUSION: From the available evidence, the use of PRF to the dorsal root ganglion in cervical radicular pain is compelling. With regards to its lumbosacral counterpart, the use of PRF cannot be similarly advocated in view of the methodological quality of the included study. PRF application to the supracapular nerve was found to be as efficacious as intra-articular corticosteroid in patients with chronic shoulder pain. The use of PRF in lumbar facet arthropathy and trigeminal neuralgia was found to be less effective than conventional RF thermocoagulation techniques
