MEWUJUDKAN MASYARAKAT DESA TUMBANG LAMPAHUNG MENUJU DESA MAJU KHUSUSNYA DALAM PENDIDIKAN BERKUALITAS, KESEHATAN DAN SUMBER DAYA

Desa maju adalah desa yang memliki potensi sumber daya sosial, ekonomi, dan ekologi serta kemampuan mengelolanya untuk meningkatkan kesejahteraan masyarakat desa, kualitas hidup manusia dan menanggulangi kemiskinan, sehingga diperlukan upaya mewujudkan desa maju yaitu dengan pemberdayaan masyarakat dalam meningkatkan kualitas hidup melalui pengembangan kemampuan masyarakat, perubahan perilaku masyarakat dan mengorganisir diri masyarakat. Tujuan pengabdian ini adalah meningkatkan pengetahuan, kesadaran, kemauan, dan kemampuan masyarakat untuk ikut perpartisipasi dalam mewujudkan desa maju. Dalam pelaksanaan pengabdian ini menggunakan sosialisasi dan pendekatan secara persuasif dengan memberi pemahaman kepada masyarakat. Desa Tumbang Lampahung adalah salah satu desa di Kecamatan Kurun, Kabupaten Gunung Mas Provinsi Kalimantan Tengah, dan merupakan desa yang baru resmi direlokasikan pada Tahun 2017 karena keadaan geografis pemukiman desa yang lama sering dilanda banjir. Penduduk Desa Tumbang Lampahung mayoritas bermata pencaharian tambang, sehingga kondisi ekonomi penduduk hanya fokus pada satu sumber mata pencaharian yang menyebabkan potensi sumber daya yang ada di desa kurang dikelola dan dikembangkan oleh masyarakat. Dari segi pendidikan Desa Tumbang Lampahung sangat kurang, mulai dari fasilitas sekolah, ketidakhadiran tenaga pendidik dalam mengajar, dan kurangnya kemampuan literasi (membaca dan menulis) siswa/i SDN Tumbang Lampahung. Dari segi kesehatan terkhusus terhadap stunting, kurangnya pengetahuan orang tua/ibu dalam pola asuh terkait masalah pemberian asupan bergizi dan sanitasi yang dapat berdampak pada bayi dan balita terkena stunting (gagal tumbuh). Dari segi pengembangan sumber daya, Desa Tumbang Lampahung belum optimal dalam mengelola potensi sumber daya. Upaya untuk membantu pihak Desa Tumbang Lampahung dalam mewujudkan desa maju dengan cara melakukan sosialisasi tentang pengelolaan kolam ikan dan pembuatan pakan ikan air tawar, sosialisasi stunting dan melakukan kegiatan budaya literasi melakui pembagian buku dan pembangunan pondok baca (gazebo

The optimization of InxGa1-xAs and InP growth conditions by CBE

Minimization of the number of experiments needed to fully characterize and optimize the growth of epitaxial material is the first important step in realizing state of the art device structures. While widely used in some fields such as chemical engineering, response surface modeling (RSM) has been little used in crystal growth applications. Using RSM, input parameters such as substrate temperature hydride injector temperature and V/III ratio, were simultaneously adjusted to characterize the crystal growth process. This technique identified interactions among parameters, minimized the number of experiments necessary to understand and optimize the process, and minimized the variability of the growth process. RSM has been applied to the CBE growth of InGaAs and InP with the purpose of generating an operating point at which both good surface morphology and high mobility material can be produced. Although the best 77 K InP mobility was 70,000 cm2/V...s, in order to improve the surface quality the input parameters were changed so that the final mobility was 37,000 cm2/V...s. Although the quality of the InGaAs layers showed a dependence on the reactor history, there did not appear to be any sensitivity to variations made in the operating conditions. The best 77 K InGaAs mobility was 62,500 cm2/V...s.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29335/1/0000402.pd

The design of an ECR plasma system and its application to InP grown by CBE

An electron cyclotron resonance (ECR) plasma system has been designed for the purpose of using an excited beam of gases during CBE growth. The system was designed to use hydrogen, nitrogen and argon. An ECR plasma system has the ability to ignite a low pressure and low temperature plasma with very low ion energies, which should minimize any damage to the growing layer. The motivation behind using a plasma during growth is the ability of atomic hydrogen to remove contaminants from the growing layer and to enhance the decomposition of organometallic precursors at low substrate temperatures. InP grown with a hydrogen plasma showed an n-type background carrier concentration of 6.0X1016 cm-3, with a rough surface and a strong photoluminescence peak at 1.378 eV. A control sample grown with excess hydrogen but without the plasma had a background carrier concentration of 1.0X1015 cm-3, a 77 K mobility of 65,000 cm2/V[middle dot]s and a very weak photoluminescence peak at 1.378 eV. The most likely cause for the layer degradation during plasma growth is an intrinsic defect such as an antisite defect or a vacancy. The n-type nature of the layer and the relatively high carrier concentration would seem to exclude the possibility of carbon or any other unintentional impurities.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29336/1/0000403.pd

Regional and racial variations in the utilization of endoscopic retrograde cholangiopancreatography among pancreatic cancer patients in the United States

BackgroundPancreatic cancer is projected to become the second leading cause of cancerâ related deaths by 2030. Endoscopic retrograde cholangiopancreatography (ERCP) is recommended as firstâ line therapy for biliary decompression in pancreatic cancer. The aim of our study was to characterize geographic and racial/ethnic disparities in ERCP utilization among patients with pancreatic cancer.MethodsRetrospective cohort study using the US Surveillance, Epidemiology, and End Results (SEER)â Medicare database to identify patients diagnosed with pancreatic cancer from 2003â 2013. The primary outcome was receipt of ERCP, with or without stent placement, vs any nonâ ERCP biliary intervention.ResultsOf the 36 619 patients with pancreatic cancer, 37.5% (n = 13 719) underwent an ERCP, percutaneous drainage, or surgical biliary bypass. The most common biliary intervention (82.6%) was ERCP. After adjusting for tumor location and stage, Blacks were significantly less likely to receive ERCP than Whites (aOR 0.84, 95% CI 0.72, 0.97) and more likely to receive percutaneous transhepatic biliary drainage (PTBD) (aOR 1.38, 95% CI 1.14, 1.66). Patients in the Southeast and the West were more likely to receive ERCP than those in the Northeast (Southeast aOR 1.21, 95% CI 1.04, 1.40; West aOR 1.16, 95% CI 1.01, 1.32).ConclusionRacial/ethnic and geographic disparities in access to biliary interventions including ERCP exist for patients with pancreatic cancer in the United States. Our results highlight the need for further research and policies to improve access to appropriate biliary intervention for all patients.To date, disparities in the receipt of endoscopic therapies among patients with pancreatic cancer have not been reported. The results from our study suggest that blacks with pancreatic cancer and patients in the Northeast region of the US are less likely to receive the gold standard therapy for obstructive jaundice.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/149758/1/cam42225_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/149758/2/cam42225.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/149758/3/cam42225-sup-0001-Supinfo.pd

Cytomegalovirus Infection of the Colon Presenting as a Mass-Like Lesion

Cytomegalovirus (CMV) is responsible for the most common opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for these infections in patients positive for human immunodeficiency virus. CMV rarely presents as an intraluminal inflammatory mass in the colon. Here we report the case of a CMV infection presenting as a mass-like lesion in an AIDS patient. The clinical diagnosis of CMV infection is largely based on the characteristic endoscopic appearance. Endoscopic procedures are encouraged early in the course of CMV infection in immunocompromised patients. CMV pseudotumors along with malignancy should be part of the endoscopic evaluation in patients with AIDS

The Gaseous Electronics Conference radio‐frequency reference cell: A defined parallel‐plate radio‐frequency system for experimental and theoretical studies of plasma‐processing discharges

A ‘‘reference cell’’ for generating radio‐frequency (rf) glow discharges in gases at a frequency of 13.56 MHz is described. The reference cell provides an experimental platform for comparing plasma measurements carried out in a common reactor geometry by different experimental groups, thereby enhancing the transfer of knowledge and insight gained in rf discharge studies. The results of performing ostensibly identical measurements on six of these cells in five different laboratories are analyzed and discussed. Measurements were made of plasma voltage and current characteristics for discharges in pure argon at specified values of applied voltages, gas pressures, and gas flow rates. Data are presented on relevant electrical quantities derived from Fourier analysis of the voltage and current wave forms. Amplitudes, phase shifts, self‐bias voltages, and power dissipation were measured. Each of the cells was characterized in terms of its measured internal reactive components. Comparing results from different cells provides an indication of the degree of precision needed to define the electrical configuration and operating parameters in order to achieve identical performance at various laboratories. The results show, for example, that the external circuit, including the reactive components of the rf power source, can significantly influence the discharge. Results obtained in reference cells with identical rf power sources demonstrate that considerable progress has been made in developing a phenomenological understanding of the conditions needed to obtain reproducible discharge conditions in independent reference cells.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70394/2/RSINAK-65-1-140-1.pd

Stereoselective, competitive, and nonlinear plasma protein binding of ibuprofen enantiomers as determined in vivo in healthy subjects

The plasma protein binding and competitive inhibition parameters of R(−)- and S(+)-ibuprofen were determined in vivo in 12 healthy subjects. Subjects participated in a 4×4 Latin square design in which oral solutions of drug were administered as 300 mg R (−)-ibuprofen, 300 mg S (+)-ibuprofen, 300 mg R (−)-+300 mg S (+)-ibuprofen, and 300 mg R(−)-+600 mg S (+)-ibuprofen. Unlabeled ibuprofen enantiomers were quantitated using a stereospecific reversed-phase HPLC assay, and plasma protein binding experiments were performed using radiolabeled 14 C-enantiomers and an ultrafiltration method at 37C. At therapeutic drug concentrations, the protein binding of each enantiomer was greater than 99%. Furthermore, the binding of ibuprofen enantiomers was Stereoselective and mutually competitive, as well as nonlinear. The bound-free data were fitted to a model in which the non-linearity of plasma protein binding and competition between enantiomers for binding sites could be accommodated. There were substantial differences in the affinity of ibuprofen enantiomers for protein binding sites (RP2=0.358±0.185 vs. SP2=0.979 ±0.501 μg/ml; X±SD) but no differences in their binding capacity (RP1=160±86 vs. SP1=161 ±63 μg/ml). Although statistically significant, the differences in competitive inhibition parameters were more modest (SKI=0.661 ±0.363 vs. RKI=0.436 ±0.210 μg/ml). As a result, the intrinsic binding (i.e.), P1/P2J of R(−)-ibuprofen was greater than S(±)-ibuprofen, and the unbound fraction was significantly greater for S-enantiomer vs. R-enantiomer after a given dose of R-ibuprofen or racemate.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45048/1/10928_2005_Article_BF01059767.pd
