Faktor-faktor kematangan implementasi e-government yang berorientasi kepada masyarakat
Authors: Wulansari Anita , Inayati Immah 
Published: May 2019

Masyarakat merupakan pemegang kepentingan utama dalam penyelenggaraan e-government. Namun demikian, dalam konteks penelitian e-government, orientasi terhadap masyarakat masih belum banyak dieksploitasi karena sebagian besar proyek e-government hanya mentransformasi layanan dan informasi yang semula masih tradisional menjadi menggunakan teknologi. Model-model penilaian kematangan e-government yang sudah ada pun sebagian besar hanya mengukur kemampuan teknologi e-government. Oleh karena itu, perlu dikembangkan penilaian kematangan e-government yang menempatkan masyarakat sebagai fokus utamanya. Faktor-faktor kematangan didapatkan melalui pendekatan penelitian kualitatif grounded theory. Objek penelitian adalah layanan e-health dan Surabaya Single Window (SSW). Hasil penelitian menunjukkan ada tiga faktor yang diukur dalam penentuan kematangan e-government yang berorientasi kepada masyarakat, yaitu lembaga, interaksi, dan layanan online. Model ini diharapkan dapat digunakan sebagai alternatif alat penilaian implementasi e-government yang lebih komprehensif karena mengukur dari tiga sisi, yaitu lembaga pemerintah, interaksi pegawai pemerintah dengan masyarakat, dan layanan e-government yang disediakan. Society is responsible for implementing e-government. Nevertheless, the context of research on e-government, orientation to society has not been exploited due to numerous projects which are only transformed service and information from previous traditional users to technology. Most of existing models of e-government was only used to determine the ability of the government. Therefore, it is necessary to develop maturity assessment of e-government placing society as major focus. Its factors are derivable from qualitative research approach of ground theory. The objects of research were e-health and Surabaya Single Window (SSW) services. The results of the study indicate that there were three factors measured in determining maturity of e-government oriented to society; the factors are institution, interaction and online services. This model could be used as more comprehensive alternative to assessment tool of e-government implementation because it measured three aspects, namely, institution, interaction of employees and provided e-government services.

Published: May 2019

The office U.S. Energy Information Administration (EIA) has suggested significant volumes of hydrocarbon resources in unconventional Shale type reservoirs, which happens to be very interesting nowadays.
The complexity of these reservoirs, along with the high level of risk during the exploration stage, and the lack of laboratory data, are challenging for an adequate estimation of hydrocarbon volumes in shale reservoirs. An innovative methodology to estimate prospective resources on a Shale reservoir is proposed in this paper, based on petrophysical and geochemical data from well logs, such as porosity, hydrocarbon saturation, TOC (total organic content), gas content, thermal rock maturity, clay fraction, thickness, rock density, etc, all of them using Monte Carlo simulation.
Further, this paper proposes a new way of interpreting petrophysical data to obtain a clearer view of reservoir characterization, especially Brittleness, which is of great relevance to define the potential of fracturing and hydrocarbon production. The methodology was applied to the Tablazo Formation in the Middle Magdalena Valley Basin (MMVB) in Colombia. The results show a total best estimate of oil in place (OOIP) of 51 637 Bls/acre, gas adsorbed in place 39.72 Mcf/acre, and free gas in place of 177.18 MCF/acre. Comparing these results with those obtained by applying other methodologies, the best estimates of oil in place is 146 933 Bls/acre, gas adsorbed in situ 40.57 MCF/acre, and free gas in place of 504.07 Mcf/acre. Data reported in the literature, on the same area, corroborate these results.
To conclude, with this methodology a new approach is achieved for estimating prospective resources in Shale reservoirs with better results using the Monte Carlo simulation.

Published: May 2019

Reverse time migration in zones with rugged topography is a method that presents some challenging issues. We present an analysis of reverse time migration in transformed domains, in particular for a technique that goes from an Euclidian to a Riemannian scenario, as suggested by some authors in previous literature. Computational results show that there is not significant improvement in the final image when the Riemannian approach is used as compared with images obtained with an Euclidean metric.

Soil texture is one of the soil properties influencing most physical, chemical, and biological soil processes. Information on soil texture is important to support the agronomic decisions for farm management. The problem is how to provide reliable, fast and inexpensive information of soil texture in numerous soil samples and repeated measurement. The objective of this research was to generate the soil texture map based on laboratory Vis-NIR (Visible - Near Infra-Red) spectroscopy and inverse distance weighted (IDW) interpolation method. An ASD Fieldspec 3 with a spectral range from 350 nm to 2500 nm was used to measure the soil reflectance. Pipette method was used to measure the silt, clay and sand fractions. The partial least square regression (PLSR) was performed to establish the prediction model of soil texture. The predicted values were mapped and showing the information of spatial and temporal variability of soil texture.

Pacitan district have an interesting anomaly. Every time mostly impacted by disaster especially landslide. Landslides in their various forms are common hazard in mountainous terrain, especially in seismically active areas and regions of high rainfall. Landslides are one of the most common natural hazards in the Southern Range East Java terrain, causing widespread damage to property and infrastructure, besides the loss of human lives almost every year. The aim of this study predicted the potential landslide using Weight of Evidence Method. The geological data used lithological data, structural data, contour data and, alteration. Results from this data analysis are six evidence maps, such as NE-SW lineament, NW-SE lineament, host rock, heat source, kaolinite alteration and iron oxide alteration maps. The geophysical data analysis the distribution of rock density to interpretation the landslides. Evidence maps were analyzed by weight of evidence methods to result in favorable maps where the validity was tested using conditional independence (CI), the pairwise and overall tests. Then, the analyses produced a posterior probability map of the landslide. Posterior probability map (mineral potential maps) was validated by checking field. Posterior probability map (after validation) or favorable map predicted approximately favorable zone and non-favourable zones. Favorable zones of Potential Landslide Hazard Zonation, are divided into three classes. They are high-potensial hazard, moderate hazard and low hazard.

Published: May 2019

Introduction: The role of free radicals and oxidative damage in the pathophysiology of vitiligo has been documented in recent studies. Antioxidant supplementation has been reported to be useful in the treatment of vitiligo.
Objective: To evaluate the role of oral antioxidants supplementation therapy in the treatment of vitiligo by assessing the onset of repigmentation and oxidative stress.
Materials and Methods: A total of 80 cases of vitiligo randomized into two groups: antioxidant and placebo comprising 40 patients each and were followed up for 8 weeks for the assessment of onset of repigmentation of vitiliginous lesions as primary outcome. The activities of Malondialdehyde (MDA), Vitamin C, and Vitamin E in serum and of Catalase (CAT) in erythrocytes of patients at baseline and at end of eight weeks were also assessed by using the spectrophotometric assay.
Results: The onset of repigmentation was noted significantly earlier among the anti-oxidant group as compared to the placebo group (p=0.015). At the baseline, between the two groups, no significant difference was found in the different biochemical parameters. However, at the end of 2 months the level of MDA (p<0.001) was found to be significantly lower and that of Vitamin E (p<0.001) and CAT (p=0.005) was significantly higher among the anti-oxidants group as compared to the placebo group.
Conclusion: Antioxidant supplementation carried a better response in terms of early onset of repigmentation and significant decrease in the oxidative stress, in the short follow up of two months.

Published: May 2019

AbstractMo2FeB2-based cermets were prepared with various Mo/B atomic ratios in the range of 0.8 to 1.1. The microstructure and crystalline phases were studied through scanning electron microscopy, transmission electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray analysis and X-ray diffractometry. The results indicated that as the Mo/B atomic ratio increased, the morphology of the hard phase gradually transformed from long-strip to near-equiaxed. The tendency of transformation in the range of 1.0 to 1.1 was more significant. Two typical cermet samples (Mo/B = 1.0, Mo/B = 1.08) of different morphologies were studied with transmission electron microscopy. As the Mo/B atomic ratio increased, the average particle size decreased, inhibiting the nucleation of the particles, the anisotropy of different crystallographic planes reduced, the particles transformed from long-strip to the near-equiaxed shape. Moreover, it could be found from X-ray diffractometry results that the disparity between the crystal lattice constants c and a gradually diminished and the surface tension differences of the amorphous surfaces decreased, resulting in the anisotropy of different crystal-lographic planes gradually decreasing. The cermets with Mo/B = 1.02 demonstrated the highest transverse rupture strength, as well as the hardness and improved fracture toughness values of 2367.5 ± 50 MPa, 88.2 ± 0.1 HRA, and 27.6 ± 0.5 MPa · m1/2, respectively.

Мета. Покращити результати пункційної вертебропластики як методу мінімально інвазивного лікування больового синдрому при травматичних та патологічних переломах хребта.
Матеріали та методи. Виконано аналіз результатів лікування хворих в Університетській клініці ОНМедУ за період з 2013 по 2018 рік. Загалом проаналізовано випадки лікування 134 хворих та виконання вертебропластики 214 хребців. З приводу гострої травми лікувалися 21 хворих (23 хребці), з приводу патологічних переломів на фоні остеопорозу проліковано 58 хворих (104 хребці), з приводу пухлинного ураження хребта – 55 хворих (87 хребців). Післяопераційний контроль виконувався інтра- та післяопераційно за допомогою флюороскопії з використанням С-дуги і, на наступний день після операції, методом комп`ютерної томографії. Виконано аналіз кількості й структури післяопераційних ускладнень та їх вплив на якість життя хворих за шкалами ВАШ (візуальна аналогова шкала болю) та FIM (functional independence measure scale). Також виконано порівняльний аналіз специфічності методів рентгенологічного контролю екстравертебрального розповсюдження полімеру (кісткового цементу).
Результати. Жодне з виявлених ускладнень не мало суттєвого клінічного впливу на перебіг захворювання. Кількість випадків екстравертебрального розповсюдження цементу, що не проявлялись клінічно, які були виявлені під час комп’ютерної томографії, значно перевищувала рентгенологічні дані. В порівнянні: 18,7 % та 4,7 % випадків ускладнень виявлені за допомогою комп’ютерної томографії та рентгенографії. Єдиний випадок емболії дрібних гілок легеневої артерії був виявлений випадково під час післяопераційного дослідження грудного відділу хребта.
Висновки. Аналіз літературних даних та власних отриманих результатів дозволяє пропонувати використання комп’ютерної томографії в післяопераційному періоді, як найбільш чутливого методу діагностики післяопераційних ускладнень пункційної вертебропластики.

Чоловік, 28 років, звернувся на консультацію зі скаргами на напади інтенсивного нестерпного (VAS 10) головного болю, які турбують з 19-річного віку. Зі слів пацієнта, тривалість нападів болю – 15–30 хвилин, частота протягом доби – 2–3 вдень і 4 вночі, в тому числі 2 напади виникають в один і той самий час – о 2-й годині ночі та о 7–8-й годині ранку. Останній напад піднімає пацієнта від сну. Серії нападів можуть виникати до 2 разів на рік, найчастіше в кінці весни або в кінці осені. Тривалість серії нападів може становити від 2–3 днів до 3 місяців, проміжки між серіями нападів (ремісії) можуть становити від 5 місяців до 2–3 років. Під час попередніх серій біль турбував у правій скроневій ділянці, правому оці, ділянці правої вилиці та верхньої щелепи справа. Під час нападів відзначає почервоніння ока, сльозотечу, відчуття закладання правої половини носа. Остання серія нападів почалася за 2 тижні до консультації, при цьому болі змістилися в ділянку лівої скроні й лівого ока (біль поміняв сторону – це буде прокоментовано окремо). Під час нападів збуджений (ажитація). Не палить зараз і не палив у минулому. Прийом алкоголю може посилити больові відчуття. Пацієнт повідомив, що в минулому через нестерпність болю була спроба самогубства.
Неврологічно: без особливостей. На представлених МРТ головного мозку відзначається вогнище лікворної щільності розмірами 0,9 × 1,9 × 1,8 см у правій скронево-лобовій ділянці конвекситально (розміри без динаміки), нерівномірно розширені конвекситальні підпавутинні простори, одиничне вогнище гліозу в правій лобовій ділянці.
