Authors: Putra Wahyu Aditama 
Published: December 2018

ABSTRAK Masalah pengangguran merupakan masalah yang tidak akan pernah habis untuk diperbincangkan. Pengangguran atau tuna karya adalah istilah bagi orang yang tidak bekerja sama sekali, sedang mencari kerja, bekerja kurang dari dua hari selama seminggu atau seseorang yang sedang berusaha mendapatkan pekerjaan yang layak. Pengangguran umumnya disebabkan karena jumlah angkatan kerja atau para pencari kerja tidak sebanding dengan jumlah lapangan kerja yang ada yang mampu menyerapnya. Penelitian ini dilakukan bertujuan untuk menguji pengaruh inflasi dan investasi terhadap pengangguran di Provinsi Jawa Timur tahun 1992-2011. Data yang digunakan adalah data sekunder. Teknik analisis yang digunakan dalam penelitian ini adalah Regresi berganda. Hasil analisis menunjukan bahwa inflasi secara parsial berpengaruh secara positif signifikan terhadap pengangguran. Berarti semakin tingginya inflasi, pengangguran meningkat. Investasi secara parsial berpengaruh negatif signifikan terhadap pengangguran. Berarti semakin tinggi investasi, pengangguran akan menurun serta Inflasi dan Investasi secara simultan berpengaruh terhadap pengangguran. Berarti semakin tinggi laju Inflasi, investasi akan meningkat dan pengangguran akan menurun. Dari hasil yang di dapat diharapkan mampu memberikan masukan kepada pemerintah agar tetap menjaga stabiltas laju inflasi dan investasi agar tingkat pengangguran menurun.

Authors: Mondal Prosanta , Lim Hyun J. , OHTN Cohort Study Team  
Published: December 2018

Background:The HIV epidemic is increasing among Men who have Sex with Men (MSM) and the risk for AIDS defining cancer (ADC) is higher among them.Objective:To examine the effect of MSM and CD4+ count on time to cancer AIDS (ADC) and noncancer AIDS in competing risks setting in the HAART era.Method:Using Ontario HIV Treatment Network Cohort Study data, HIV-positive adults diagnosed between January 1997 and October 2012 having baseline CD4+ counts ≤ 500 cells/mm3 were evaluated. Two survival outcomes, cancer AIDS and non-cancer AIDS, were treated as competing risks. Kaplan-Meier analysis, Cox cause-specific hazards (CSH) model and joint modeling of longitudinal and survival outcomes were used.Results:Among the 822 participants, 657 (79.9%) were males; 686 (83.5%) received anti-retroviral (ARV) ever. Regarding risk category, the majority (58.5%) were men who have Sex with men (MSM). Mean age was 37.4 years (SD = 10.3). In the multivariate Cox CSH models, MSM were not associated with cancer AIDS but with non-cancer AIDS [HR = 2.92; P = 0.055, HR = 0.54; P = 0.0009, respectively]. However, in joint models of longitudinal and survival outcomes, MSM were associated with cancer AIDS but not with non-cancer AIDS [HR = 3.86; P = 0.013, HR = 0.73; P = 0.10]. CD4+ count, age, ARV ever were associated with both events in the joint models.Conclusion:This study demonstrates the importance of considering competing risks, and timedependent biomarker in the survival model. MSM have higher hazard for cancer AIDS. CD4+ count is associated with both survival outcomes.

Authors: Yousif Nooraldaem , Shahin Mohammady , Manka Robert , Obeid Slayman 
Published: December 2018

Background:
Coronary artery fistula (CAF) is an abnormal communication between the
termination of a coronary artery or its branches and a cardiac chamber, a great vessel or other vascular
structure. Symptomatic patients with large CAF should undergo surgical or percutanous closure
of the fistula at the drainage site while still the debate on closing asymptomatic CAF and reopening
symptomatic occluded CAF is ongoing.

Case Summary:
We are reporting a 30-year-old male patient with no previous medical history presented
as non-ST segment elevation myocardial Infarction. Coronary angiography showed an entirely
thrombosed ectatic circumflex artery with a suspicion of thrombosed coronary arterial fistula.
In view of the ongoing ischemia in the setting of acute coronary syndrome; we tried to open percutaneously
but all efforts were to no avail.

Discussion:
In this case report, we are sharing our experience in the management of this challenging
case in view of the rarity of such peculiar clinical condition and the unfavourable presentation
along with the lack of clear-cut Guideline and Consensus whether to/not to open such huge and
immensely thrombosed symptomatic coronary artery fistula as well as the dilemma of choosing the
best long-term medical treatment between antiplatelets vs anticoagulants in such young patient.

Published: December 2018

Background:
With easy accessibility to combination Antiretroviral Therapy (cART), mortality amongst hospitalized HIV/AIDS patients needs to be described.

Objective:
We aimed at determining the trends, causes and factors associated with in-hospital mortality amongst HIV/AIDS patients in the Douala General Hospital.

Methods:
We retrospectively reviewed hospitalisation records of HIV/AIDS patients hospitalized in the medical wards of the DGH from 2007 to 2015. Four cause-of-death categories were defined: 1. Communicable conditions and AIDS-defining malignancies, 2. Chronic non-communicable conditions and non-AIDS defining malignancies’, 3. Other non-communicable conditions and 4. Unknown conditions. Logistic regression was used to determine factors associated mortality.

Results:
We analyzed 891 eligible files. The mean age was 43 (standard deviation (SD): 10) years and median length of hospital stay was 9 (interquatile range (IQR)4 - 15) days. The overall all-cause mortality was 23.5% (95% CI: 20.8% - 26.4%). The category - communicable conditions and AIDS defining malignancies represented 79.9%, of deaths and this remained constant for each year during the study period. Tuberculosis was the most common specific cause of death (23.9%). Patients who had two (OR=2.35, 95%CI: 1.35 - 4.06) and more than two (OR=4.23, 95%CI: 1.62 – 11.12) opportunistic infections, a haemoglobin level less than 10g/l (OR=2.38, 95%CI: 1.58 - 3.59) had increased odds of dying.

Conclusion:
In-hospital mortality is high amongst HIV/AIDS patients at the Douala general hospital. The category - communicable conditions and AIDS defining malignancies - is still the main underlying cause of death. We hope that our findings will help to develop interventions aimed at reducing in-hospital mortality.
A Comparative Study of Computational Intelligence Algorithms for Sensor Localization
Authors: Kulkarni Vaishali R. , Desai Veena , Kulkarni Raghavendra 
Published: December 2018

Background & Objective:Location of sensors is an important information in wireless sensor networks for monitoring, tracking and surveillance applications. The accurate and quick estimation of the location of sensor nodes plays an important role. Localization refers to creating location awareness for as many sensor nodes as possible. Multi-stage localization of sensor nodes using bio-inspired, heuristic algorithms is the central theme of this paper.Methodology:Biologically inspired heuristic algorithms offer the advantages of simplicity, resourceefficiency and speed. Four such algorithms have been evaluated in this paper for distributed localization of sensor nodes. Two evolutionary computation-based algorithms, namely cultural algorithm and the genetic algorithm, have been presented to optimize the localization process for minimizing the localization error. The results of these algorithms have been compared with those of swarm intelligence- based optimization algorithms, namely the firefly algorithm and the bee algorithm. Simulation results and analysis of stage-wise localization in terms of number of localized nodes, computing time and accuracy have been presented. The tradeoff between localization accuracy and speed has been investigated.Results:The comparative analysis shows that the firefly algorithm performs the localization in the most accurate manner but takes longest convergence time.Conclusion:Further, the cultural algorithm performs the localization in a very quick time; but, results in high localization error.

AbstractThe ionic (proton and deuteron) conductivity of the system CaZr_1 – _ x Sc_ x O_3 – α ( x = 0.03–0.20) is studied experimentally in H_2 + H_2O + N_2 and D_2 + D_2O + N_2 reducing atmospheres at p H_2O = p D_2O = 3.2 kPa and in the temperature range of 600–900°C. This system exhibits a considerable H/D isotopic effect in conductivity, and its magnitude is estimated. Using theoretical elaborations, we also estimate the magnitude of the thermodynamic isotope effect in the solubility of H_2O/D_2O in the considered system under reducing conditions.
Reading for Soldiers and People: the Phenomenon of “Soldiers’ Library” of V.A. Berezovsky
Authors: Panchenko Anatoly M. 
Published: December 2018

The article is devoted to the well-known serial edition “Soldatskaya Biblioteka” [Soldiers’ Library] of V.A. Berezovsky, the commission agent of the Ministry of Defence, private publisher and bookseller of military literature. Since 1888, most of the works were published and republished under the title “Reading for Soldiers and People” and from 1894 to 1915 — “Soldiers’ Library”. The purpose of this large publishing project of V.A. Berezovsky was to promote intellectual and spiritual moral development and self-education of the lower military ranks. By 1915, twenty-five serial sets of “Soldiers’ library” — twenty stories in each — were published. Separate sets and works were repeatedly republished. The aim of the study is to show the noticeable role of cheap illustrated “military and moral” books in the acquisition of libraries for the lower ranks and company book collections of military educational institutions. The author collected the data about all serial sets and runs of “Soldiers’ Library” by 1915, its acquisition and distribution. The article presents the analysis of the authors and the content of the library, its presence in military and civil book collections.Commercial entrepreneurial spirit, common sense and taste of V. Berezovsky himself, the appropriate choice of authors and their works, low prices, design, accessibility and accuracy of the publications were of great importance in gaining the great popularity of the “Soldiers’ Library”. Its active advertising campaign, conducted through the official structures of the military and other Departments, as well as through the printed publications owned by V. Berezovsky, contributed to its promotion to soldiers-readers. Therefore, some of the works from the “Soldiers’ Library” were purposfully admitted for acquisition of book collections of lower schools, free folk libraries and reading rooms and were recommended for home reading for cadets of primary schools.The results of study demonstrate that the “Soldiers’ Library” was available in the catalogues of book collections for lower ranks, in company schools, in battalion, squadron, crew, battery and regimental educational teams of military units and military schools. The experience of edition of “Soldiers’ Library” was popular in the years of Soviet power: it was used in the series “Library of Red Army Soldier”, “Popular Scientific Library of Soldier” and “Bibliotechka of the ‘Sovetsky Voin’ magazine” [Library of the “Soviet Soldier” Magazine].

BackgroundPneumonia remains the foremost cause of death in children under 5 years of age especially in sub-Saharan Africa killing nearly 1 million annually.Aim Identify pneumonia prevalence, mortality rate and associated factors among children under five admitted to Komfo Anokye Teaching Hospital (KATH) in Ghana.MethodsUsing a prospective cross-sectional study method, a consecutive sample of 157 children under 5 admitted to the KATH for pneumonia from June to August 2016 was selected. A structured questionnaire was used to collect primary data from their caregivers and secondary data from the patient record using a structured data extraction form. Continuous and categorical variables were described and chi-square test employed to determine the associated factors of pneumonia mortality. Multivariate logistics regression model was used to test for the strength of the association to unearth the risk factors of pneumonia mortality.Results The study found a prevalence of pneumonia of 18.40% with a mortality rate of 12.74%. Pneumonia mortality was found to be associated with maternal education (p<0.001), occupation (p=0.01), income (p=0.02), pneumonia severity (p<0.001) and number of rooms occupied by a household (p=0.01). In multivariate regression, severe pneumonia increased the odds of pneumonia mortality (OR=18.23, 95% CI= 4.37-76.10, p<0.001). However, maternal education showed reduced likelihood of pneumonia mortality (OR=0.59, 95% CI= 0.36-0.97, p=0.039). ConclusionPneumonia places a high burden on the health of children under five years admitted to KATH. Health workers need to sensitize caregivers on the signs and symptoms of pneumonia to aid early detection and reporting which could reduce mortality.

Published: December 2018

Listening is considered as the basic skill in learning a language. Listening lets students gain input in the form of audio. Due to the 2013 curriculum, schools are provided with English textbook prepared by the government. This textbook is used for the listening input which may affect the output of listening process. Therefore, the researchers are interested in conducting a research related to the weaknesses of the K13 English textbook When English Rings a Bell. The researchers want to know the weaknesses of the listening material in the textbook which can be known from the teachers’ perception. This research used qualitative and quantitative method. The instruments of this research are observation, questionnaire, and interview. The result of the study shows that there are several weaknesses of the listening material existing in the K13 English textbook. These weaknesses may affect to the output of language learning and cannot develop students’ listening skill. Therefore, it is expected that the government would take more attention on the listening material for students to help them better input for listening activity.
