Published: May 2020

Prevalensi hipertensi di Jakarta pada usia lebih dari 18 tahun mencapai 46,25% pada wanita dan 41,97% pada pria, sedangkan 63,2% kasus hipertensi di masyarakat tidak terdiagnosis. Berbagai faktor risiko hipertensi ditemukan di banyak tempat termasuk di lingkungan kerja. Kebisingan adalah salah satu bahaya fisik yang dapat mempengaruhi tekanan darah dan merupakan faktor risiko untuk hipertensi. Penelitian ini dilakukan untuk mengidentifikasi hubungan antara kebisingan dan beberapa faktor di tempat kerja dengan prevalensi hipertensi. Studi cross-sectional dilakukan untuk mengetahui hubungan antara tingkat paparan kebisingan, masa kerja, penggunaan APD, dan karakteristik individu dan hipertensi. Sampel 104 pekerja diambil dari para pekerja di PT X. Data dikumpulkan melalui pemeriksaan fisik dan kuesioner. Analisis bivariat menggunakan uji Chi-Square menunjukkan bahwa intensitas kebisingan (p = 0,001), BMI (p = 0,001) dan kebiasaan merokok (p = 0,006) adalah determinan independen untuk peningkatan tekanan darah. Responden yang terpapar bising lebih dari ≥85 desibel (dB) memiliki 19.8 risiko hipertensi lebih besar dibandingkan dengan mereka yang terpapar kebisingan <85 dB. Ada pola respon-paparan yang signifikan (P = 0,001) antara risiko hipertensi dan intensitas paparan kebisingan. Studi ini menunjukkan bahwa paparan kebisingan di tempat kerja dapat meningkatkan risiko terhadap terjadinya peningkatan tekanan darah. Kata kunci: Kebisingan, Masa Kerja, APD, Tekanan Darah, Hipertensi

KAJI EKSPERIMENTAL PENGARUH BAFFLE PADA ALAT PENUKAR PANAS ALIRAN SEARAH DALAM UPAYA OPTIMASI SISTEM PENGERING
Authors: Azwinur Azwinur , Zulkifli Zulkifli
Published: May 2020

Heat exchangers or heat exchangers are tools used to change the temperature of the fluid or change the fluid phase by exchanging heat with another fluid. In a heat exchanger, the ability to exchange heat is largely determined by the type of fluid flow and fluid passing through the heat exchanger. The use of heat exchangers in the field of drying is now a necessity to overcome the problems of drying productivity. The purpose of this study was carried out to determine the effectiveness of the heat exchanger experimentally based on directional flow by comparing construction using baffle and without using baffle in an effort to optimize the drying system. The research method was carried out by fabricating 2 units of heat exchangers and by field testing. The test data obtained are the input and output temperatures of the heating fluid flow and cooling fluid flow and flow velocity. Based on preliminary research data shows that the use of baffle affects the increase in temperature on the heat exchanger, where at the fresh air outlet that does not use baffle produces a temperature of 72oC while the baffle produces 88oC with the Log Mean Temperature Difference heat exchanger without using a baffle higher than heat exchanger that uses a baffle guide blade. This can illustrate that the smaller heat losses are wasted so that the absorption of heat by the reverse system will be higher.

Published: May 2020

Academic advisors in higher education are often incoming students’ first exposure to college curriculum and academic expectations. Additionally, academic advisors serve as an on-going support to students throughout their college careers. As the number of students beginning college full-time with a significant amount of dual enrollment (DE) credits increases, academic advisors must develop approaches to advising this population of students based on academic and developmental needs. This study explored the approaches college academic advisors take when advising high DE credit-bearing incoming college students.
Model of Fracture Propagation in Hydraulic Isolation of the Wellbore
Authors: Lapin V. N.
Published: May 2020

A model of fracture initiation and propagation along the boundary of a cement plug and a steel casing in a plugged wellbore is proposed. The model allows predicting the conditions of hydraulic isolation failure of a cement plug induced by reservoir pressure. The model describes the stress state of the cement and it’s breakaway from the steel casing caused by the pressure of the pore fluid flowing into the fracture. Numerical experiments show that the fracture propagation velocity and the stability of the hydraulic isolation are sensitive to the reservoir pressure and to the prestressed state of the cement. It is shown also that the quality of cement adhesion to steel and the size of the initial cementing defects have little effect on the initiation conditions and fracture propagation velocity.
Continuous Pile and Column Foundations of Towers in Siberian Towns and Ostrogs
Authors: Gorokhov Sergey V.
Published: May 2020

Purpose. In the course of archaeological research of Russian ostrogs (wooden fortresses) in Siberia, which belong to the end of the 16th – the first half of the 18th centuries, researchers come across remains of defensive fortifications, interpretation of which is rather complicated. Such remains include traces of continuous pile and column foundations of ostrog towers. The objective of this article is to identify all known structures of this type, determine essential elements of their construction and discover the functional purpose of such a foundation.
Results. In the course of archаeological research, four towers with continuous pile and column foundation were discovered, namely, a south-western tower of Umrevinskii Ostrog, one of Tobolsk towers, a south-eastern tower and a north-western tower of Udinskii Ostrog. Information on discovery of towers with such a foundation in Mangazeya was not confirmed. The existence of such a foundation under the western tower of the Sosnovskii Ostrog remains disputable. One of such towers preserved its original foundation in the town of Bel’sk (Irkutsk region) till 1987. Three towers with continuous pile and column foundations were discovered in Krasnoyarskii Ostrog in written sources.
Conclusion. It is determined that all towers were located on the slope or next to it, their dimensions were considerably smaller than average ones, while their depth and thickness of logs were equal and met the same parameters of the lath fence walls. Such towers were intended first for reducing a load on unstable grounds on the slopes and next to them at the expense of small sizes of towers and secondly for preventing uneven subsidence of the tower bases, which due to a small perimeter thereof can result in a considerable lurch and subsequent collapse or damage of the structural integrity of the building.
The Calcite (104) Surface - Electrolyte Structure: A 3D Comparison of Surface X-Ray Diffraction and Simulations
Authors: Brugman Sander , Raiteri Paolo , Accordini Paolo , Megens Frank , Gale Julian , Vlieg Elias
Published: May 2020

Adsorption and incorporation of ions is known to influence the morphology and growth of calcite. Using surface X-ray diffraction, the interfacial structure of calcite in contact with CaCO3, MgCl2, CaCl2and BaCl2 solutions was determined. All of these conditions yield a comparable interfacial structure,meaning that there is no significant ion adsorption. This allows for the first time a thorough comparison in all three dimensions with state-of-the-art computer simulations, involving molecular dynamicsbased on both DFT and two different force field models. Additionally, the simulated structures areused to calculate the corresponding structure factors, which in turn are compared to those obtainedfrom experiment, thereby avoiding the need for fitting or subjective interpretation. In general, thereis a good agreement between experiment and the simulations, though there are some small discrepancies in the atomic positions, which lead to an inadequate fit of certain features characteristic of thestructure of water at the interface. Of the three simulation methods examined, the DFT results werefound to agree best with the experimental structure.

Bu araştırmanın amacı bir kamu politikası olarak yürütülen bağımlılıkla mücadeleye ilişkin uygulamaların muhtarlar tarafından nasıl algılandığını incelemektir. Araştırmada nicel araştırma yöntemi kullanılmış veriler anket tekniği ile elde edilmiştir. Verilerin analizinde SPSS 18 programından yararlanılmıştır. Yapılan araştırma sonucunda bağımlılıkla mücadele çalışmalarında köy ve mahalle muhtarlarının çoğunluğunun bağımlılıkla mücadele konusundaki algılarının bir plan ve yöntem dâhilinde yeniden harekete geçirilmeye ihtiyaçlarının olduğu anlaşılmaktadır. Gelinen noktada muhtarların nasıl mücadele edileceği konusundaki bilgi ve motivasyon eksikliğinden dolayı aktif olamadıkları ve mevcut potansiyellerini kullanamadıkları düşünülmektedir. Dolayısıyla bir kamu politikası olarak bağımlılıkla mücadelede köy ve mahalle muhtarlarının hem suç ve suçluların ortaya çıkarılmasında, hem de önleme faaliyetlerinde, aktif rol almasını sağlayacak işbirliği ve projelere çok büyük ihtiyaç olduğu söylenebilir.
HARMONIC REGRESSION ANALYSIS OF TERROR EVENTS IN TURKEY: PERIODICITIES AND FORECASTING
Authors: KARAMANOĞLU Yunus Emre , AKDİ Yılmaz
Published: May 2020

In the study, the number of terrorist incidents occurred during 2001/01-2012/11 periods in Turkey's Southeast region are studied. Since Southeast region has the highest number of terrorist incidents in Turkey, Southeast region is selected. The data used in the study is obtained by special permission from official institutions. In this study, the periodicities observed during the period are examined and it is tried to obtain a meaningful predictive model by using harmonic regression and classical time series techniques. Harmonic regression and classical time series techniques have been shown to give better predictions in the application of periodic series. According to the results, predictions obtained by harmonic regression model are closer to the real values. However, it is determined that the acts of terrorism in Turkey show an increase in every 72 months-6 years period, and the observed periodicities are interpreted. So, it is important not to allow terrorist organizations to recover in the fight against terrorism. Considering such periodicities, it is important to share the results with the relevant units dealing with terrorism globally.
STATE FRAGILITY AND POST-CONFLICT STATE-BUILDING: AN ANALYSIS OF SOUTH SUDAN CONFLICT (2013-2019)
Authors: AGWANDA Billy , ASAL Uğur Yasin
Published: May 2020

The South Sudan conflict flared up in 2013 hardly two years after successful secession from Sudan. This autonomy was achieved after more than two decades of intense fighting between the tribes from the north and south regions of Sudan. However, the path to creating a new united and modern state has been challenging for South Sudan. This article explores post-conflict reconstruction for Africa’s newest state through an in-depth analysis of the conflict narratives, peace processes, humanitarian crisis and the challenges of state-building for South Sudan. The article argues that the challenge to the establishment of a strong and stable South Sudanese state is because of the fragile social, political and economic status that the country inherited at independence. This article also identifies that ethnicity has been exploited by the different political actors in the conflict to achieve personal and group interests leading to outbreak of one of the most intense conflicts not only within Africa, but also globally.
CURRENT CHALLENGES AND TRENDS IN INTELLIGENCE
Authors: ATEŞ Ahmet
Published: May 2020

After a thorough examination of current intelligence literature, a variety of national security documents and respected news outlets, I find several current challenges in intelligence under different areas. I classify current major challenges in intelligence into four groups. These are technological, financial, organizational, and political. Technological challenges are the most important ones because other challenges are either related to it or a result of it. These are the expansion of using meta-data, the expansion of social media, and cybersecurity. The second current challenge in intelligence is financial. It is mostly about the use of cryptocurrencies. The third challenge is organizational. These are the impact on information revolution on intelligence organizations and competition with non-intelligence organizations. The last current challenge in intelligence is political. Political challenges are populist nationalist movements, ISIS returnees, and expansion of hybrid warfare. Related to current challenges in intelligence and the global security environment, there are eight current trends in intelligence. Five of them are mostly related to technological challenges, while three of them are related to political challenges. The trends that are related to technological challenges in intelligence are the foundation of cyber intelligence divisions/agencies, the change in recruitment policies, the rising importance of the security of cyberinfrastructure, privatization of intelligence, and increasing role of open-source intelligence. The trends that are related to political challenges in intelligence are the increasing focus on right-wing groups, the elimination of ISIS returnees, and the increasing role of intelligence in hybrid warfare/covert operations.

Published: May 2020

Matematiksel modeller aracılığıyla fail profillemesini esas alan çalışma, öngörüsel metotlarla ortaya çıkarılan tespitlerin adli bilimlerde kullanılabileceği gerçeğinden yola çıkarak tasarlanmıştır. Çalışmanın temel problemi, malvarlığına karşı işlenen suçlar özelinde suçun aydınlatılmasında sosyo-kültürel değişkenlerin (cinsiyet, yaş, eğitim düzeyi, ortalama gelir, vb.) geçerliliğini test etmektedir. Soruşturma birimleri tarafından adli vakalarda elde edilen maddi deliller haricinde mülakat süreci ile yapılan bilgi toplamalar, olayın çözümlenmesine büyük katkı sağlamaktadır. Bununla beraber mülakat sürecini şekillendiren detaylara dair failin sosyo-demografik özelliklerini göz önünde bulundurarak geliştirilen modeller sayesinde sonuca gidilmesi yeni değildir, ancak Türkiye özelinde önermeler geliştirilmesi konusunda saha çalışmaları oldukça kısıtlıdır.

Bu çalışma İstanbul, Ankara ve İzmir illerindeki ceza infaz kurumlarında bulunan 154 tutuklu veya mahkûmun gönüllülük esasına dayalı katılımıyla gerçekleştirilen nicel araştırma sonucunda suçlu profillerini CHAID algoritmasını esas alarak tespit etmeyi amaçlamaktadır. Yapılan karar ağacı analizi sonuçlarına göre; mala zarar verme, hırsızlık ve yağma (gasp) suçları özelinde profillemeye imkân tanıyan sosyo-demografik değişkenlerin ortaya çıkarılması sağlanmıştır. Elde edilen sonuçların soruşturma birimleri tarafından dikkate alınması ve mikro ölçekli yerel birimlere uygulanması sayesinde adli bilimler alanında farkındalık oluşturacağı düşünülmektedir.
CARD-NOT-PRESENT FRAUD VICTIMIZATION: A ROUTINE ACTIVITIES APPROACH TO UNDERSTAND THE RISK FACTORS
Authors: AKDEMİR Naci , YENAL Serkan
Published: May 2020

Banking cards, including credit cards, debit card, pre-paid debit cards and ATM cards, have become the primary payment method in online transactions. However, this popularity boosted the Card-not-present (CNP) fraud victimization. Despite numerous studies exploring technological solutions to prevent CNP fraud, there is a shortage of theoretically informed research exploring the online lifestyle correlates of CNP.

This study, which utilizes the dataset of Crime Survey for England and Wales 2014/2015, addresses this gap in the literature. Routine Activities Theory was used as the theoretical and conceptual framework in this present study. Bivariate and multivariate analyses results suggested that home users’ online lifestyle increases the risk of becoming a victim of CNP fraud. Buying goods or services, accessing online government services and online communication (email/instant messaging and chat rooms) emerged as risk factors. Illustrating the impact of technological vulnerabilities (mobile phones and public access computers) on the risk of CNP fraud victimization was another novel contribution of this study.

Additionally, personal guardianship measures, using complex passwords and different passwords, emerged as predictors of victimization. These results provide valuable implications for situational crime prevention efforts. Practical and theoretical implications of this study are further discussed.

The metallization and the phase transition of the alkali bromide sodium bromide (NaBr) is investigated through its band structure. The equilibrium lattice constant, bulk modulus, pressure derivative of bulk modulus and the phase transition pressure at which the compound undergo structural phase transition from NaCl (B1) to the CsCl (B2) structure is predicted from the total energy calculations. The ground state properties and band gap values are compared with the experimental and other theoretical results. At normal pressure NaBr is a direct band gap insulator. When the pressure is increased there is enhanced overlapping between the wave functions of the neighboring atoms. As a result the widths of the valence and empty conduction bands increase. These changes lead to the narrowing and indirect closing of band gap in NaBr (metallization). It is also confirmed that the metallization and structural phase transition do not occur simultaneously in ionic compounds.

Proliferating Cell Nuclear Antigen Expression in Canine and Feline Spontaneous and Injection-site Fibrosarcomas
Authors: Ahmed Ishtiaq
Published: May 2020

Fibrosarcoma, a tumor composed of spindloid fibroblasts, is grouped in soft tissue sarcomas which constitute one of the most important tumors in companion animals. Cell proliferation index is a good indicator of the biological behavior of the tumors which is estimated either by mitotic index or cell proliferation markers. In the current study, we investigated the immunohistochemical expression of proliferating cell nuclear antigen (PCNA) in spontaneous and injection-site fibrosarcomas in dogs and cats. A positive correlation was noticed between the PCNA expression, mitotic index, tumor grade and degree of differentiation of the tumor cells in tumors from both of these species. PCNA expression was significantly different between different tumor grades in dogs and cats. It can be concluded from this study that PCNA is a useful marker for predicting the outcome of the canine and feline fibrosarcomas
Seroprevalence and Risk Factors of Equine Glanders in Selected Districts of Khyber Pakhtunkhwa (KPK)
Authors: Sial Awais-Ur-Rehman
Published: May 2020

Glanders is highly contagious and zoonotic bacterial disease of equines caused by Burkholderia mallei. Since many decades, glanders is endemic in eastern parts (Punjab) of Pakistan and has no information of disease in the north-western region (Khyber Pakhtunkhwa – KPK). Therefore, present study was aimed to determine the seroprevalence and associated risk factors in two draft equine populated districts (Charsada and Peshawar) of KPK. A total of 393 equine samples originating from different localities of study area were investigated for anti-B. mallei antibodies (glanders) using indirect enzyme linked immunosorbent assay (ID Vet, Grabels France). The overall seroprevalence was found to be 3.1% (95% CI: 1.6-5.3) which remained insignificantly (χ2 0.421, P=0.516) between the two districts. In Charsada, prevalence estimates varied significantly (χ2 11.986, P=0.017) among 5 localities and found insignificant (χ2 1.287, P=0.732) in different sampling areas of Peshawar district. Donkeys were more seropositive (4.1%; 4/195) than horses (2.1%; 8/194) which did not differ statistically (χ2 1.397, P=0.237) and all mules were tested negative. Prevalence slight increased with age of animals (>10 years) and with poor body conditions. Donkeys were more test positive (OR: 2.05, 95% CI: 0.61-6.94) than horses and similarly animals managed on communal feeding (OR: 1.84, 95% CI: 0.23-14.5) and water troughs (OR: 1.65, 95% CI: 0.21-13.04) had more chances of contracting glanders. Multivariable model indicated donkeys (OR: 4.58, 95% CI: 1.0, 20.9) and equines above 10 years of age (OR: 3.10, 95% CI: 0.7-13.3) were more likely to test positive for glanders. In conclusion, present study provides prevalence estimates of equine glanders in KPK regions, which appears to be an area of endemicity. Future large-scale investigations are seriously warranted in other equine populated districts before implementing an effective control plan for glanders

Bukti digital sangat penting dalam pembuktian kasus kejahatan komputer yang melibatkan perangkat penyimpanan. Salah satu media penyimpanan terkini saat ini adalah SSD NVMe, secara default sistem operasi Windows 10 terpasang TRIM dengan mode enable, fungsi TRIM mengoptimalkan kinerja kecepatan SSD NVMe dengan cara menghapus otomatis data lama pada sebuah sektor sebelum ditempatkan data baru sehingga menjadi tantangan investigator untuk mengembalikan bukti digital. Tujuan penelitian melakukan analisis bukti digital yang terhapus dengan metode penghapusan permanen dengan cara shift delete dan delete, delete recycle bin menggunakan tools forensics yang berbeda untuk mengembalikan bukti digital pada SSD NVMe TRIM enable. Metode yang digunakan static forensics sedangkan tools yang digunakan FTK Imager, Autopsy dan Recuva. Hasil analisis TRIM enable metode penghapusan shift delete tidak ditemukan bukti digital yang sesuai nilai hash dengan bukti digital asli. Sedangkan metode penghapusan delete, delete recycle bin bukti digital dapat dikembalikan dengan  prosentase keberhasilan menggunakan  tool Autopsy sebesar 90% dan 10% nilai hash bukti digital tidak valid, sedangkan tool Recuva 80% bukti digital berhasil dikembalikan dan 20% tidak berhasil dikembalikan, dapat disimpulkan hasil recovery penghapusan delete, delete recycle bin pada SSD NVME TRIM enable dapat dijadikan bukti digital yang sah menurut hukum.Kata-kata kunci: Forensika digital, Restorasi, Hapus Permanen, NVMe, NIST
Kajian Penyebab Jalan Ambles Pada Ruas Jalan Banjarparakan-Menganti Kabupaten Banyumas
Authors: Azizi Amris , Salim M. Agus
Published: May 2020

Ruas jalan Banjarparakan-Menganti Kabupaten Banyumas telah beberapa kali mengalami ambles dan longsor lereng pada titik yang sama. Ambles dan longsor menimbulkan masalah transportasi karena ruas jalan ini merupakan jalan utama di Desa Banjarparakan Kecamatan Rawalo. Ambles dan longsor meliputi hampir seluruh lebar badan jalan dengan panjang longsoran lebih kurang 50 meter. Penanganan yang dilakukan selama ini belum menghasilkan solusi yang baik, karena longsor dan ambles masih terjadi.Tujuan penelitian adalah mengkaji karakteristik tanah dasar jalan dan stabilitas lereng ruas jalan Banjarparakan-Menganti. Kajian dilakukan untuk menemukan jawaban penyebab terjadinya longsor lereng dan ambles di ruas jalan Banjarparakan-Menganti. Karakteristik tanah dasar dianalisis dengan pendekatan parameter batas-batas Atterberg, dan stabilitas lereng dianalisis dengan software Geostudio Slope/WHasil analisis menunjukkan bahwa tanah dasar dibawah timbunan ruas jalan Banjarparakan-Menganti adalah endapan fluvial yang sangat mudah sekali longsor bila tidak dalam kondisi tertahan. Tanah dasar (subbase) ruas jalan Banjarparakan-Menganti mempunyai nilai PI = 11,4%, termasuk tanah lempung berlanau, kohesif dan mempunyai sifat plastisitas sedang. Tanah jenis ini mempunyai karakteristik tanah yang kurang baik, karena sering menimbulkan penurunan yang berlebihan, gerakan dinding penahan tanah, keruntuhan lereng, dan lain-lain. Stabilitas lereng ruas jalan Banjarparakan-Menganti eksisting pada tiga stasiun pengamatan termasuk kategori stabil. Penyebab longsor lereng dan amblesnya ruas jalan Banjarparakan-Menganti diperkirakan karena pemancangan tiang pancang tidak mencapai tanah keras, tambahan beban dinding penahan tanah pada lereng, dan pengaruh tekanan air pori yang diperkirakan cukup besar, terutama bila terjadi hujan.
