Published: July 2019

A região do Pontal do Paranapanema, localizada no Oeste do Estado de São Paulo, possui 117 assentamentos rurais frutos do processo de Reforma Agrária, se configurando como uma das regiões do Brasil onde a questão agrária se torna mais latente, sobretudo pela concentração de assentamentos rurais e quantidade de família assentadas. Diante disso, nos chama a atenção as discussões sobre as formas de reprodução destas famílias camponesas, das quais destaca-se a subordinação ao capital agroindustrial, levando-os à integração por meio da produção de pepinos para conserva. Os resultados da pesquisa revelam a subordinação da renda e do trabalho das famílias mostrando como essa dinâmica de produção controla o tempo, a produção e o trabalho e como coloca em risco a saúde das famílias pela quantidade de agrotóxicos utilizados.
İşsizliğin Azaltılmasında Kamusal Bir İstihdam Modeli Olarak Nihai İşveren Programı
Authors: ÖZDEMİR Dicle
Published: July 2019

Bu çalışmanın amacı, Hyman Minsky'nin hükümetler tarafından fiyat istikrarı
altında tam istihdama nasıl ulaşılabileceğine dair bir heterodoks politika
önerisi olan devletin nihai işveren olma politikasını değerlendirmek ve bu
yaklaşımın avantajlarını ve dezavantajlarını kavrayabilmek için temel teorik
çerçevede tartışmaktır. Program, hükümet tarafından finanse edilen ve iş
arayan, ancak iş bulamayan ve kamu sektörü projelerinde çalışmaya hazır olan
tüm işsizleri ise alarak sıfır işsizlik elde etmeyi amaçlayan bir kamu istihdam
politikasıdır. Bu nedenle, bu çalışma, programın etkilerini analiz etmek için
kavramsal bakış açısının kısa bir analizi ile başlamaktadır ve bunu daha sonra
bu programın sabit fiyat kuralı üzerinde çalışan bir tampon stok mekanizması
olarak nasıl çalıştığı üzerine odaklanan bir analiz izleyecektir. Bu tür bir
politika özellikle Türkiye gibi işgücünün çoğunluğunun gayri resmi sektörlerde
sosyal güvence olmaksızın çalışmak zorunda kaldığı ülkeler için kritik öneme
sahiptir zira etkin bir nihai işveren programı altında çalışmanın sosyal yardım
ve güvenliğe katkı sağlayacağından ve yoksul kesim açısından işgücü
piyasalarının etkinliğini arttıracağından şüphe yoktur.

Authors: KARSLIOĞLU İdris
Published: July 2019

Gri pazarlama ve paralel ithalat kavramları, yıllardır özellikle markalı ürünler üreten işletmeler ve aynı ürünü daha ucuza almak isteyen tüketiciler tarafından önemle incelenen bir konudur. Bu kavramlar, fiyat farklarının olduğu piyasalarda kendini göstermekte, tüketici ihtiyaç ve beklentilerine göre pek çok üründe daha da derinlik kazanmaktadır. Gri pazarlama ve paralel ithalat şeklinde ithalat yoluyla yurtdışından getirilen ürünler, yurtiçi piyasada satılan ürünlerin önünde bir engel gibi görünmekteyse de günümüzde birçok dağıtıcı işletme tarafından teşvik edilmekte ve gittikçe tüketiciler tarafından daha çok tercih edilmektedir. Çalışmada, gri pazarlama, paralel ithalat ve geri ithalat kavramlarına değinilerek, konuyla ilgili yapılan çalışmalar incelenmektedir. Örnek olay analizinin yapıldığı çalışmada, cep telefonlarının fiyat farklılıkları tespit edilerek gri ürün ve paralel ürünün tercih sebepleri açıklanmaktadır. Kişisel beklentiler üzerindeki fayda ve zararları ele alınarak geliştirilen çeşitli stratejilere değinilmektedir. Çalışmanın sonucunda, gri pazarlama ve paralel ithalatın yurtiçinde satışa sunulan ürünlerin pazar payını etkilediği, tüketici için karlı ancak dağıtıcı açısından karı düşürücü yapısının olduğu ortaya çıkmaktadır.

Published: July 2019

Monodora myristica is one of the plants used extensively in folkloric medicine across West Africa. Despite the ethnopharmacological relevance of the plant, the phytochemical details, especially of the oil-rich seed, have not been completely elucidated. This study was designed to ascertain the phytochemical constituents of extracts of M. myristica seed oil and characterize the oil constituent using gas chromatography-mass spectrometry. The phytochemical screening was done using standard methods and the oil was characterized by GC-MS analysis. The result of the phytochemical screening showed the presence of terpenoids, sterols, saponins, tannins, flavonoids and cardiac glycoside in variable quantities. The GC-MS analysis revealed huge presence of fatty acids, terpenoids and other related compounds. The major compounds found in the oil of the seeds were o-cymene (2), γ-terpinene (3), nopinane (4), limonene (5), carvotanacetone (6), β-pinene (7), aromadendrene (9), germacrene (11), α-amorphene (13) and copaene (14). The rich phytoconstituents present in the seed oil could be the basis of its acclaimed ethnomedicinal uses across West Africa and beyond.

Published: July 2019

Masih tingginya angka kematian ibu dan bayi membuat pemerintah berusaha keras untuk meningkatkan kualitas hidup. Salah satunya yaitu pelaksanaan Inisiasi Menyusu Dini. Namun kenyataannya banyak ibu menolak untuk melakukannya. Berdasarkan data  yang diperoleh dari Dinas Kesehatan Kota Binjai Tahun 2015, cakupan IMD Kota Binjai hanya 11% dari yang ditargetkan sebesar 80%. Data yang diperoleh dari RS Tentara Binjai Tahun 2015 cakupan IMD 1,28%, tahun 2016 cakupan IMD  0,98%, dan tahun 2017 sebesar 0,92% dari yang ditargetkan 80%. Tujuan  penelitian ini adalah Menganalisis  sebab-sebab kegagalan Inisiasi Menyusui Dini pada ibu post sectio caesaria di Rumah Sakit Tentara Binjai tahun 2018. Jenis penelitian ini menggunakan metode penelitian deskriptif  kualitatif dengan 3 informan ibu, 3 informan suami, dan 3 informan bidan perujuk dan bidan penanggung jawab yang bertugas di ruang rawat inap sebagai pemberi asuhan persalinan serta dilakukan triangulasi data untuk menjaga validitas data.  Berdasarkan hasil wawancara dan pengamatan ditemukan kurangnya pengetahuan ibu tentang pentingnya pelaksanaan IMD disebabkan karena kurangnya informasi yang diberikan oleh tenaga kesehatan,  dukungan suami, serta motivasi, baik dari bidan perujuk pada saat kunjungan kunjungan ANC maupun peran dari bidan yang bertugas di rumah sakit yang seharusnya memfasilitasi ibu melakukan IMD. Maraknya promosi susu formula di media massa, teman, penawaran langsung ke ibu, menyebabkan timbulnya pola fikir ibu yang beranggapan susu formula sama baiknya dengan ASI. Diharapkan agar Rumah Sakit Tentara Binjai yang merupakan faktor  paling berpengaruh sebagai tempat rujukan agar melakukan sosialisasi kebijakan dan mendukung program IMD antara lain mengupayakan standar prosedur operasional terkait pelaksanannya, pengawasan dan evaluasi menuju keberhasilan menyusui.
Diffuse Lymph-Nodes Microangiopathy as Concurrent Cause of Immunodeficiency in Long-Term Insulin-Dependent Diabetic Patients
Authors: Muretto Pietro
Published: July 2019

Immune abnormalities have been demonstrated in vitro models in genetic (type1) autoimmune (type 2) and metabolic (type 1 and type 2) Insulin-Dependent Diabetes Mellitus (IDDM). However, the precise reason for increased susceptibility to frequent and protracted infections in diabetic patients is still unclear, despite a multitude of in vitro studies which have focused on the metabolic and functional modifications of immune cells Diabetes microangiopathy, which is a peculiar alteration of the disease, has been extensively described in the retina, renal glomeruli, skin, skeletal muscles, peripheral nerves, and other organs but not in lymph nodes. We report our histological and immunohistochemical observations in lymph-nodes removed in multiple sites during autopsy from four patients with long-term IDDM, severe lymphocytpenia and several infectious diseases during their life. The peculiar microangiopathic modifications made by presence of hyaline substance thickening basal membrane of thin vessels and capillaries appear concurrent with lymphodepletion of B and T cells dependent areas of lymph-nodes and with jointed marked reduction of Follicular Dendritic Reticulum Cells (FDRC). Indeed microangiopathy further compromise the traffic and diapedesis of T and B lymphocytes may prevent the transformation of endothelial cells into FDRC with severe immune failure of lymphoid follicles. The histological and immunohistochemical data in this study could provide additional insights into the complex problem of the immunodeficiency in diabetic patients.

Antioxidants and flavonoids are beneficial compounds used in the pharmaceutical and food industries that are derived from natural sources. A two-year field experiment was undertaken to investigate the effect of agricultural management practices on the trigonelline content, antioxidant activity measured with DPPH (2,2-Diphenyl-1-Picrylhydrazyl) and FRAP (Fe+++-Reduction, Ferric reducing antioxidant power), total phenolic content, total flavonoids content, and specific flavonoid contents of fenugreek seeds. The treatments examined were sole fenugreek (Sole F) and three intercropping ratios with buckwheat (B) (F:B = 2:1, 1:1, and 1:2), each with three types of fertilizer (chemical fertilizer, integrated fertilizer, and broiler litter). The highest trigonelline content of fenugreek seeds was obtained in F:B = 2:1 fertilized with broiler litter. Compared to Sole F, the fenugreek seeds harvested in the intercropped treatments had higher antioxidant activity, total phenolic content, vitexin, isovitexin, orientin, and isoorientin. The treatment F:B = 2:1 enhanced the antioxidant activity and the content of bioactive compounds. Overall, the addition of organic manure to fenugreek seeds was highly effective at promoting all compounds analyzed in both the sole and the intercrop systems. Our study found that harvested fenugreek seeds from plants that were intercropped with buckwheat and with the application of organic fertilizer enhanced the seed content of antioxidants and flavonoids.

In this work the polymerization of catechin, epicatechin, and resveratrol was carried out through a peroxidase oxidation process in order to improve the biological activity of these phenolic compounds. The antioxidant activity of the oligomers was evaluated by their ability to scavenge reactive oxygen species (ROS) and their capacity to chelate metal ions Fe2+ and Cu2+. The antitumor effect of the oligomers was determined by their ability to induce toxicity in the T24 human bladder cancer cell line. By enzymatic peroxidase oxidation, it was possible to produce oligomers of catechin, epicatechin, and resveratrol with antioxidant capacity significantly higher than their preceding monomers. The ROS scavenging capacity of the oligomers was 20 times higher than that of the monomers, while the ability of the oligomers to chelate metal ions increased up to about 1000 times. Our data show the antitumor effect of the oligomers of catechin, epicatechin, and resveratrol in the T24 cell line, which was similar to that observed with cisplatin. Oligomers of catechin, epicatechin, and resveratrol have great potential to be used as therapeutic agents for the treatment of oxidative stress-related diseases and bladder cancer.

This paper presents an experimental investigation on chemical grouting in a permeated fracture replica considering its roughness. Tests of grouting with flowing water in the fracture replica were carried out under different Bardon’s standard roughness profiles. The interactions between influential factors were considered and an experimental platform for grouting in rough fractures with flowing water was established. The effect of chemical grouting in fractures with flowing water was investigated using orthogonal experiment. The joint roughness coefficient (JRC), the initial water flow rate, the gel time, and the fracture opening were selected as factors in the orthogonal experiment. The results show that there is a positive correlation between the water plugging rate and JRC, and negative correlations between the water plugging rate and the initial water flow rate, gel time, and fracture opening. The change curve of the water flow rate is divided into three categories: Single platform decreasing type, double platform decreasing type, and multi-peak fluctuating type. The curve of seepage pressure contains three categories: Single peak type, multi-peak type and platform type. The results provide a reference for grouting in rock fractures.

Software Defect Prediction (SDP) models are built using software metrics derived from software systems. The quality of SDP models depends largely on the quality of software metrics (dataset) used to build the SDP models. High dimensionality is one of the data quality problems that affect the performance of SDP models. Feature selection (FS) is a proven method for addressing the dimensionality problem. However, the choice of FS method for SDP is still a problem, as most of the empirical studies on FS methods for SDP produce contradictory and inconsistent quality outcomes. Those FS methods behave differently due to different underlining computational characteristics. This could be due to the choices of search methods used in FS because the impact of FS depends on the choice of search method. It is hence imperative to comparatively analyze the FS methods performance based on different search methods in SDP. In this paper, four filter feature ranking (FFR) and fourteen filter feature subset selection (FSS) methods were evaluated using four different classifiers over five software defect datasets obtained from the National Aeronautics and Space Administration (NASA) repository. The experimental analysis showed that the application of FS improves the predictive performance of classifiers and the performance of FS methods can vary across datasets and classifiers. In the FFR methods, Information Gain demonstrated the greatest improvements in the performance of the prediction models. In FSS methods, Consistency Feature Subset Selection based on Best First Search had the best influence on the prediction models. However, prediction models based on FFR proved to be more stable than those based on FSS methods. Hence, we conclude that FS methods improve the performance of SDP models, and that there is no single best FS method, as their performance varied according to datasets and the choice of the prediction model. However, we recommend the use of FFR methods as the prediction models based on FFR are more stable in terms of predictive performance.
