Published: February 2018

Background
Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism.

Objective
The main objective of this study was to validate the French version of the WART.

Methods
Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers’ sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients).

Results
Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI −9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity.

Conclusions
The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.
Towards evolutionary agroecology
Authors: Mercer Kristin L. 
Published: February 2018

Agroecology derives much of its strength from interactions between disciplines that produce a holistic perspective on agricultural systems and issues. Although ongoing integration of social dynamics into agroecology has strengthened the field, evolution and genetics have not been embraced to the same degree, despite the fact that they have been are discussed in some common agroecology texts. I argue that the field of agroecology could extend its reach and depth by embracing the evolutionary study of agroecosystems. Areas of evolutionary inquiry with relevance to agriculture focus on long or short term processes, encompass a range of scales, incorporate molecular or quantitative genetic analyses, and explore ecological processes to differing degrees.

INFLUENCES OF SHORT-TERM NORMOBARIC HYPOXIC TRAINING ON METABOLIC SYNDROME-RELATED MARKERS IN OVERWEIGHT AND NORMAL-WEIGHT MEN
Authors: Shin Sohee , Matsuoka Toshio , So Wi-Young 
Published: February 2018

Background and Objective
This study examined the influence of short-term normobaric hypoxic training on metabolic syndrome-related markers in overweight and normal-weight men.
Material and Methods
Forty-one Japanese men were included and were divided into two groups based on their body mass indices (BMIs): BMI≥25 or BMI<25. Participants in the overweight and normal-weight groups were randomly classified into the hypoxic exercise group (hypoxic overweight, HO; hypoxic normal-weight, HN) and the normoxic exercise group (normoxic overweight, NO; normoxic normal-weight, NN). Subjects performed treadmill exercise three days per week for four weeks at an exercise intensity of 60% of maximum heart rate, under either normobaric hypoxic or normobaric normoxic conditions, for 50 min (including 5 min warm-up and cool-down periods) after a 30-min rest period. The study parameters included weight, body fat percentage, BMI, heart rate, waist circumference, ankle-brachial pulse wave velocity (PWV), blood sugar, triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) scores, and adiponectin levels. Repeated measures two-way analysis of variance was used to examine differences in the mean parameter values between the two groups (overweight and normal-weight) before and after training.
Results
Hypoxic training improved the weight, body fat percentage, BMI, waist circumference, PWV, TC, LDL-C levels, and HOMA-IR scores in the overweight and normal-weight groups (p<0.05). In addition, TG level, HDL-C level, and HOMA-IR scores showed significant interactions with hypoxic training, as these parameters improved in the hypoxic overweight group (p<0.05).
Conclusion
These results suggest that hypoxic training could be useful for improving arterial stiffness, circulatory system function, body composition, and energy metabolism in adult males.

Has been done research on modeling the image of the aquifer using geoelectric method. This research was conducted on 7 conditions by taking one data at each condition there is condition without being given a model, model conditions flats have not given water and by water, aquifer conditions concave not given water and by water, and aquifer conditions veined not given water and by water this so can get to see the image data inversion results of resistivity using Res2dinv. Modeling the aquifer flat using geoelectric method obtained the image in the form of layers of images with different colors in which this is due to the material composition and water content are different. Modeling the concave aquifer using geoelectric obtained the aquifer at a depth of 15-30 cm with blue color because in this area the water content is more than other areas. Modeling a branched aquifer using geoelectric method obtained the image in the form of two points aquifer detached in blue, this is two water sources. In the image modeling of aquifers using geoelectric method the resistivity value lower aquifer region compared to other regions as indicated by the color of light blue until dark.
Performance Evaluation of Mobile Base Station under different Network Sizes on Cluster-Based Wireless Sensor Networks
Authors: Tohma Kadir , Abasıkeles-Turgut Ipek , Kutlu Yakup 
Published: February 2018

The position of the base station (BS) in wireless sensor networks (WSNs) has a significant
impact on network lifetime. This paper suggests a mobile BS positioning algorithm for clusterbased
WSNs, which considers both the location and the remaining energy level of the cluster
heads in the network and evaluate the performance of the algorithm under different values of
network sizes, including 100m x 100m, 200m x 200m and 300m x 300m. Simulations are
conducted by using OMNeT++ and proposed method is compared with two different static BS
positions, including central and external, on HEED protocol. The results show that mobile BS
performs better than both central and external BS positions under all network sizes. Besides,
the performance difference between the proposed method and the others increases as the size
of the network increases, which demonstrates that the proposed mobile BS positioning also
provides scalability.&nbsp;

Many different approaches for neural network based hash functions have been proposed.
Statistical analysis must correlate security of them. This paper proposes novel neural hashing
approach for gray scale image authentication. The suggested system is rapid, robust, useful
and secure. Proposed hash function generates hash values using neural network one-way
property and non-linear techniques. As a result security and performance analysis are
performed and satisfying results are achieved. These features are dominant reasons for
preferring against traditional ones.
Environmental DNA for Detection of Endangered Grouper Species (Epinephelus spp.)

Published: February 2018

Marine ecosystems nestle species or populations known to be threatened due to human
overexploitation. Reliable detection and monitoring of threatened organisms is crucial for
data-driven conservation actions. Furthermore, misidentification of species represents a major
problem. Here, we investigate the potential of using metabarcoding of environmental DNA
(eDNA) obtained directly from seawater samples to detect endangered grouper species
(Epinephelus spp.). Cytochrome c oxidase subunit I (COI) fragment of mtDNA was used to
detect groupers species in the Mediterranean Coasts. We conducted eDNA sampling at sites
by underwater diving across the range of the Grouper species habitats in Northeastern
Mediterranean (Antalya-Kas Region and Iskenderun Bay). eDNA was isolated from 2 liter
seawater samples which were vacuum-filtered onto 0.45-mm membrane filters. Filters were
then folded inwards, placed in 2 ml tubes and stored at -20 oC until DNA extraction, which
took place within 24 hours. DNA was extracted from the water sample filters using the
DNeasy Blood and Tissue Kit (Qiagen, USA). Manufacturer’s protocols were used during all
steps. PCR amplification of eDNA samples were done using selective primers of COI region
of mitochondrial DNA, and next-generation DNA sequencing of PCR application was
conducted. For the successfully obtained COI sequences, maximum matching rates were
revealed as 80% for Epinephelus marginatus, 78,95% for Epinephelus aeneus, 73,48% for
Epinephelus costae, 63,45% for Epinephelus caninus, 60,12% for Mycteroperca rubra and
57,12% for Hyporthodus haifensis. Despite the methodological challenges inherent in eDNA
analysis, the results demonstrated that eDNA method may be proved to step towards a new
beginning to detect and monitor endangered grouper species.

Published: February 2018

Auscultation is a method for diagnosis of especially internal medicine diseases such as cardiac,
pulmonary and cardio-pulmonary by listening the internal sounds from the body parts. It is the
simplest and the most common physical examination in the assessment processes of the clinical
skills. In this study, the lung and heart sounds are recorded synchronously from left and right
sides of posterior and anterior chest wall and back using two digital stethoscopes in Antakya
State Hospital. The chest X-rays and the pulmonary function test variables and spirometric
curves, the St. George respiratory questionnaire (SGRQ-C) are collected as multimedia and
clinical functional analysis variables of the patients. The 4 channels of heart sounds are focused
on aortic, pulmonary, tricuspid and mitral areas. The 12 channels of lung sounds are focused on
upper lung, middle lung, lower lung and costophrenic angle areas of posterior and anterior sides
of the chest. The recordings are validated and labelled by two pulmonologists evaluating the
collected chest x-ray, PFT and auscultation sounds of the subjects. The database consists of 30
healthy subjects and 45 subjects with pulmonary diseases such as asthma, chronic obstructive
pulmonary disease, bronchitis. The novelties of the database are the combination ability between
auscultation sound results, chest X-ray and PFT; synchronously assessment capability of the
lungs sounds; image processing based computerized analysis of the respiratory using chest X-ray
and providing opportunity for improving analysis of both lung sounds and heart sounds on
pulmonary and cardiac diseases.

Published: February 2018

Dalam upaya mengurangi ketergantungan terhadap bahan bakar fosil terutama bahan bakar minyak (BBM), Pemerintah Indonesia menargetkan penggunan bahan bakar nabati (BBN) seperti bioetanol dan biodiesel sebanyak 5% pada tahun 2025. Kendala utama dalam hal pengembangan BBN ini adalahadanya kompetisi bahan baku BBN dengan penyediaan bahan pangan, keterbatasan dalam hal sarana dan prasarana serta kendala non teknis lainnya misalnya berupa fluktuasi harga minyak mentah dunia. Bila kondisi harga minyak mentah dunia naik, maka kondisi ini akan mendorong upayadiversifikasi energi, demikian pula sebaliknya. Pada penelitian ini, dilakukan perhitungan produktifitas BBN biodiesel mikroalga dengan membandingkan harga produksinya dengan harga minyak mentah dunia. Mengacu pada hasil perbandingan biaya produksi mikroalga dengan harga minyak mentah jugadianalisis upaya peningkatan nilai profitabilitas biodiesel mikroalga dengan meningkatkan efisiensi produktivitas melalui pemanfaatan limbah sebagai input produksi dan meningkatkan produk tambahan, serta penambahan inovasi produksi dengan pemanfaatan limbah dan penganekaragaman produk. Hasilperhitungan menyatakan bahwa pada kondisi harga minyak mentah sebesar 70 US$/barel maka biaya produksi bahan baku minyak alga tidak boleh lebih dari Rp. 6.180,-/liter. Penambahan inovasi produksi dengan pemanfaatan limbah dan penganekaragaman produk dapat meningkatkan profitabilitas sebesar 14,2% dan 30,5% atau menurunkan biaya produksi biodiesel dari Rp. 9.025,-/liter menjadi Rp.6.270,/liter.

Authors: Dewanti Dian Purwitasari 
Published: February 2018

Peningkatan luas lahan perkebunan kelapa sawit dan produksinya menimbulkan permasalahan sampah. Berdasarkan data BPS tahun 2015, produksi kelapa sawit di Indonesia mencapai 31,07 juta ton per tahun. Sebesar 23% dari total produksi kelapa sawit tersebut merupakan Tandan Kosong Kelapa Sawit (TKKS). Hanya 10% dari TKKS yang sudah dimanfaatkan untuk bahan bakar boiler dankompos padahal banyak sekali produk yang bisa dibuat dari hasil pengolahan TKKS. Salah satu pemanfaatan TKKS adalah dengan mengekstraksi selulosa sebagai bahan baku bioplastik ramah lingkungan. Hal ini akan membantu permasalahan lingkungan yang ditimbulkan oleh kelapa sawit danpemakaian plastik sudah sangat banyak. Kandungan selulosa dalam TKKS sebesar 30-40% berat. Penelitian ini bertujuan menghitung potensi selulosa dari TKKS dengan mengekstraksi selulosa sehingga didapatkan yield selulosa yang terekstraksi. Selulosa dari TKKS tersebut diekstraksi dengan dua tahapan proses yaitu delignifikasi menggunakan natrium hidroksida (NaOH) 12% selama 3 jamdilanjutkan bleaching dengan hidrogen peroksida (H2O2) 10% selama 1,5 jam. Dari hasil ekstraksi tersebut didapatkan yield selulosa sebesar 34%. Dari hasil tersebut dapat disimpulkan bahwa selulosa memiliki potensi yang sangat besar untuk diproduksi dari TKKS sehingga memenuhi kebutuhan bahan baku bioplastik.
