In this paper, we report the development of a portable energy-efficient interrogator (Perrogator) for wavelength-based optical sensors. The interrogator is based on a compact solution encompassing a white light source and the spectral convolution between the sensor and a tunable filter, which is acquired by a photodetector, where a microcontroller has two functions: (i) To control the filter tuning and to (ii) acquire the photodetector signal. Then, the data is sent to a single-board computer for further signal processing. Furthermore, the employed single-board computer has a Wi-Fi module, which can be used to send the sensors data to the cloud. The proposed approach resulted in an interrogator with a resolution as high as 3.82 pm (for 15.64 nm sweeping range) and maximum acquisition frequency of about 210 Hz (with lower resolution ~15.30 pm). Perrogator was compared with a commercial fiber Bragg grating (FBG) interrogator for strain measurements and good agreement between both devices was found (1.226 pm/µε for the commercial interrogator and 1.201 pm/µε for the proposed approach with root mean square error of 0.0144 and 0.0153, respectively), where the Perrogator has the additional advantages of lower cost, higher portability and lower energy consumption. In order to demonstrate such advantages in conjunction with the high acquisition frequency allowed us to demonstrate two wearable applications using the proposed interrogation device over FBG and Fabry-Perot interferometer (FPI) sensors. In the first application, an FBG-embedded smart textile for knee angle assessment was used to analyze the gait of a healthy person. Due to the capability of reconstructing the FBG spectra, it was possible to employ a technique based on the FBG wavelength shift and reflectivity to decouple the effects of the bending angle and axial strain on the FBG response. The measurement of the knee angle as well as the estimation of the angular and axial displacements on the grating that can be correlated to the variations of the knee center of rotation were performed. In the second application, a FPI was embedded in a chest band for simultaneous measurement of breath and heart rates, where good agreement (error below 5%) was found with the reference sensors in all analyzed cases.

Published: July 2019

The accurate severity classification of a bug report is an important aspect of bug fixing. The bug reports are submitted into the bug tracking system with high speed, and owing to this, bug repository size has been increasing at an enormous rate. This increased bug repository size introduces biases in the bug triage process. Therefore, it is necessary to classify the severity of a bug report to balance the bug triaging process. Previously, many machine learning models were proposed for automation of bug severity classification. The accuracy of these models is not up to the mark because they do not extract the important feature patterns for learning the classifier. This paper proposes a novel deep learning model for multiclass severity classification called Bug Severity classification to address these challenges by using a Convolutional Neural Network and Random forest with Boosting (BCR). This model directly learns the latent and highly representative features. Initially, the natural language techniques preprocess the bug report text, and then n-gram is used to extract the features. Further, the Convolutional Neural Network extracts the important feature patterns of respective severity classes. Lastly, the random forest with boosting classifies the multiple bug severity classes. The average accuracy of the proposed model is 96.34% on multiclass severity of five open source projects. The average F-measures of the proposed BCR and the existing approach were 96.43% and 84.24%, respectively, on binary class severity classification. The results prove that the proposed BCR approach enhances the performance of bug severity classification over the state-of-the-art techniques.

Published: July 2019

Advances in embedded electronic systems, the development of new communication protocols, and the application of artificial intelligence paradigms have enabled the improvement of current automation systems of energy management. Embedded devices integrate different sensors with connectivity, computing resources, and reduced cost. Communication and cloud services increase their performance; however, there are limitations in the implementation of these technologies. If the cloud is used as the main source of services and resources, overload problems will occur. There are no models that facilitate the complete integration and interoperability in the facilities already created. This article proposes a model for the integration of smart energy management systems in new and already created facilities, using local embedded devices, Internet of Things communication protocols and services based on artificial intelligence paradigms. All services are distributed in the new smart grid network using edge and fog computing techniques. The model proposes an architecture both to be used as support for the development of smart services and for energy management control systems adapted to the installation: a group of buildings and/or houses that shares energy management and energy generation. Machine learning to predict consumption and energy generation, electric load classification, energy distribution control, and predictive maintenance are the main utilities integrated. As an experimental case, a facility that incorporates wind and solar generation is used for development and testing. Smart grid facilities, designed with artificial intelligence algorithms, implemented with Internet of Things protocols, and embedded control devices facilitate the development, cost reduction, and the integration of new services. In this work, a method to design, develop, and install smart services in self-consumption facilities is proposed. New smart services with reduced costs are installed and tested, confirming the advantages of the proposed model.

Published: July 2019

The consequences of falls, costs, and complexity of conventional evaluation protocols have motivated researchers to develop more effective balance assessments tools. Healthcare practitioners are incorporating the use of mobile phones and other gadgets (smartphones and tablets) to enhance accessibility in balance evaluations with reasonable sensitivity and good cost–benefit. The prospects are evident, as well as the need to identify weakness and highlight the strengths of the different approaches. In order to verify if mobile devices and other gadgets are able to assess balance, four electronic databases were searched from their inception to February 2019. Studies reporting the use of inertial sensors on mobile and other gadgets to assess balance in healthy adults, compared to other evaluation methods were included. The quality of the nine studies selected was assessed and the current protocols often used were summarized. Most studies did not provide enough information about their assessment protocols, limiting the reproducibility and the reliability of the results. Data gathered from the studies did not allow us to conclude if mobile devices and other gadgets have discriminatory power (accuracy) to assess postural balance. Although the approach is promising, the overall quality of the available studies is low to moderate.

Published: July 2019

Computer simulation is an effective means for the research of robot navigation algorithms. In order to implement real-time, three-dimensional, and visual navigation algorithm simulation, a method of algorithm simulation based on secondary development of Unity3D is proposed. With this method, a virtual robot prototype can be created quickly with the imported 3D robot model, virtual joints, and virtual sensors, and then the navigation simulation can be carried out using the virtual prototype with the algorithm script in the virtual environment. Firstly, the scripts of the virtual revolute joint, virtual LiDAR sensors, and terrain environment are written. Secondly, the A* algorithm is improved for navigation in unknown 3D space. Thirdly, taking the Mecanum wheel mobile robot as an example, the 3D robot model is imported into Unity3D, and the virtual joint, sensor, and navigation algorithm scripts are added to the model. Then, the navigation is simulated in static and dynamic environments using a virtual prototype. Finally, the navigation tests of the physical robot are carried out in the physical environment, and the test trajectory is compared with the simulation trajectory. The simulation and test results validate the algorithm simulation method based on the redevelopment of Unity3d, showing that it is feasible, efficient, and flexible.

Published: July 2019

This study aims to identify the factors determining the forestry household income in South Korea. An empirical analysis was conducted on the Korea Forest Service’s 3-year-panel data. Korea Forest Service is an institution responsible for the sustainable management of South Korea’s forest lands. In the study, the hypothesized factors determining the forestry household income are classified into four types of assets and three types of livelihood strategies. The forestry household income (FHI) is divided into three elements: forestry income (FI), non-forestry income (NFI), and transfer income (TI). The influence of household assets and livelihood strategies on each income were also assessed. A random effect model was used as a statistical analysis of the three-year data of 979 forestry households. Based on the analysis, we found that household head’s age, household head’s labor capacity, savings, business type, cultivated land size, and region are significantly associated with FHI. While FI was influenced by labor capacity, cultivated land size, business type, forestry business portfolio, and region, NFI was determined by household head’s age, household head’s gender, forestry business portfolio, and savings. TI was affected by household head’s age, household head’s education level, forestry business portfolio, savings, and region. The effect sizes and directions varied across different types of income (FHI, FI, NFI, and TI). The findings showed that South Korea forestry was highly dependent on sustainable assets and livelihood strategies. Based on our findings, we expect the effectiveness of forest policies in increasing the forestry household income would differ depending on the source of each income. The results of this study draw attention to the need for an income support policy which considers the characteristics of household assets and livelihood strategies in order to enhance FHI in South Korea.
Destination Assessment and Certification: Challenges and Opportunities
Authors: Grapentin Stephan , Ayikoru Maureen
Published: July 2019

This study examines recent developments in destination assessment and certification as a basis for identifying challenges and benefits they engender, from tourist and tourism organizations’ perspectives. It uses online surveys and semi-structured interviews to collect primary data from prospective tourists and key informants on destination assessment and certification. The findings highlight the strengths and weaknesses of schemes currently in use, including various factors that might influence their future development. Specifically, the study finds that destination assessment and certification are affected by four key issues, namely, practicability, reliability, visibility, and (un)availability of incentives. It concludes that the manifestation of these issues and their ensuing complexity affect the way in which tourists and tourism destinations engage with destination assessment and certification. This, therefore, delimits the inherent opportunities and constraints within such schemes.
Exploring Socio-Cognitive Mindfulness in the Context of Sustainable Consumption
Authors: Helm Sabrina , Subramaniam Brintha
Published: July 2019

Mindfulness has been presented as a consumer characteristic mitigating negative environmental effects of overconsumption. This study argues that consumers’ propensity to engage in sustainable consumption behaviors additionally depends on individual values and beliefs, developing a more nuanced view of mindfulness in this particular domain of consumer behavior. Based on an online survey among 546 American consumers, the study finds that mindfulness not only affects a set of sustainable consumption behaviors directly, but also has an impact on environmental concern and perceived consumer effectiveness, accounting for an indirect positive effect of mindfulness through these values and beliefs. Materialism is negatively associated with mindfulness. However, certain forms of sustainable consumption behaviors may offer a pathway for materialist consumers to participate in sustainable consumption. Research findings indicate that increased mindfulness may be effective in changing daily consumption routines, helping to reduce negative environmental impacts of overconsumption, particularly in populations with increased environmental concern and perceived consumer effectiveness.
Solar Photovoltaic Electricity Generation: A Lifeline for the European Coal Regions in Transition
Authors: Bódis Katalin , Kougias Ioannis , Taylor Nigel , Jäger-Waldau Arnulf
Published: July 2019

The use of coal for electricity generation is the main emitter of Greenhous Gas Emissions worldwide. According to the International Energy Agency, these emissions have to be reduced by more than 70% by 2040 to stay on track for the 1.5–2 °C scenario suggested by the Paris Agreement. To ensure a socially fair transition towards the phase-out of coal, the European Commission introduced the Coal Regions in Transition initiative in late 2017. The present paper analyses to what extent the use of photovoltaic electricity generation systems can help with this transition in the coal regions of the European Union (EU). A spatially explicit methodology was developed to assess the solar photovoltaic (PV) potential in selected regions where open-cast coal mines are planned to cease operation in the near future. Different types of solar PV systems were considered including ground-mounted systems developed either on mining land or its surroundings. Furthermore, the installation of rooftop solar PV systems on the existing building stock was also analysed. The obtained results show that the available area in those regions is abundant and that solar PV systems could fully substitute the current electricity generation of coal-fired power plants in the analysed regions.
Automatic Vehicle License Plate Extraction Using Region-Based Convolutional Neural Networks and Morphological Operations
Authors: Kim JongBae
Published: July 2019

The number and range of the candidate vehicle license plate (VLP) region affects the result of the VLP extraction symmetrically. Therefore, in order to improve the VLP extraction rate, many candidate VLP regions are selected. However, there is a problem that the processing time increases symmetrically. In this paper, we propose a method that allows detecting a vehicle license plate in the real-time mode. To do this, the proposed method makes use of the region-based convolutional neural network (R-CNN) method and morphological operations. The R-CNN method is a deep learning method that selects a large number of candidate regions from an input image and compares them to determine whether objects of interest are included. However, this method has limitations when used in real-time processing. Therefore, to address this limitation in the proposed method, while selecting a candidate vehicle region, the selection range is reduced based on the size and position of the vehicle in the input image; hence, processing can be performed quickly. A vehicle license plate is detected by performing a morphological operation based on the edge pixel distribution of the detected vehicle region. Experimental results show that the detection rate of vehicles is approximately 92% in real road environments, and the detection rate of vehicle license plates is approximately 83%.
Using Reflection Symmetry to Improve the Protection of Radio-Electronic Equipment from Ultrashort Pulses

Published: July 2019

The paper considers the protection of critical radio-electronic equipment (REE) from ultrashort pulses (USP) by means of modal filters (MFs). A new approach to improve modal filtration by using reflection symmetry is analyzed. The results of a sophisticated research into protective devices based on reflection symmetric MFs are presented: improving the characteristics of four MFs through optimization both by one and simultaneously by several criteria; calculating the per-unit-length time delays matrix of a reflection symmetric MF using the obtained analytical expressions; calculating the time and frequency responses of an MF with and without losses in conductors and dielectric; developing the laboratory evaluation board; analyzing the effect of moisture protection on the characteristics; analyzing the features of reflection symmetry structures; comparing microstrip and reflection symmetric four-conductor MFs. The obtained results allow us to argue that the reflection symmetric MF protects REE from a USP due to its decomposition into a sequence of pulses with pairwise equalized voltage amplitudes and close time intervals between decomposition pulses with an attenuation coefficient of four times with a controlled bandwidth of a useful signal. This research helps take advantage of the possibilities of using the symmetry to improve modal filtering and opens the ways to create a large number of new MF designs, applying only the principles of the symmetry described in the work.
On Some Formulas for Kaprekar Constants
Authors: Yamagami Atsushi , Matsui Yūki
Published: July 2019

Let b ≥ 2 and n ≥ 2 be integers. For a b-adic n-digit integer x, let A (resp. B) be the b-adic n-digit integer obtained by rearranging the numbers of all digits of x in descending (resp. ascending) order. Then, we define the Kaprekar transformation T ( b , n ) ( x ) : = A − B . If T ( b , n ) ( x ) = x , then x is called a b-adic n-digit Kaprekar constant. Moreover, we say that a b-adic n-digit Kaprekar constant x is regular when the numbers of all digits of x are distinct. In this article, we obtain some formulas for regular and non-regular Kaprekar constants, respectively. As an application of these formulas, we then see that for any integer b ≥ 2 , the number of b-adic odd-digit regular Kaprekar constants is greater than or equal to the number of all non-trivial divisors of b. Kaprekar constants have the symmetric property that they are fixed points for recursive number theoretical functions T ( b , n ) .

Published: July 2019

Both ricin and R. communis agglutinin (RCA120), belonging to the type II ribosome-inactivating proteins (RIPs-Ⅱ), are derived from the seeds of the castor bean plant. They share very similar amino acid sequences, but ricin is much more toxic than RCA120. It is urgently necessary to distinguish ricin and RCA120 in response to public safety. Currently, mass spectrometric assays are well established for unambiguous identification of ricin by accurate analysis of differentiated amino acid residues after trypsin digestion. However, diagnostic peptides are relatively limited for unambiguous identification of trace ricin, especially in complex matrices. Here, we demonstrate a digestion strategy of multiple proteinases to produce novel peptide markers for unambiguous identification of ricin. Liquid chromatography-high resolution MS (LC-HRMS) was used to verify the resulting peptides, among which only the peptides with uniqueness and good MS response were selected as peptide markers. Seven novel peptide markers were obtained from tandem digestion of trypsin and endoproteinase Glu-C in PBS buffer. From the chymotrypsin digestion under reduction and non-reduction conditions, eight and seven novel peptides were selected respectively. Using pepsin under pH 1~2 and proteinase K digestion, six and five peptides were selected as novel peptide markers. In conclusion, the obtained novel peptides from the established digestion methods can be recommended for the unambiguous identification of ricin during the investigation of illegal use of the toxin.
A HERO for General Relativity
Authors: Iorio Lorenzo
Published: July 2019

HERO (Highly Eccentric Relativity Orbiter) is a space-based mission concept aimed to perform several tests of post-Newtonian gravity around the Earth with a preferably drag-free spacecraft moving along a highly elliptical path fixed in its plane undergoing a relatively fast secular precession. We considered two possible scenarios—a fast, 4-h orbit with high perigee height of 1047 km and a slow, 21-h path with a low perigee height of 642 km . HERO may detect, for the first time, the post-Newtonian orbital effects induced by the mass quadrupole moment J 2 of the Earth which, among other things, affects the semimajor axis a via a secular trend of ≃4–12 cm yr − 1 , depending on the orbital configuration. Recently, the secular decay of the semimajor axis of the passive satellite LARES was measured with an error as little as 0 . 7 cm yr − 1 . Also the post-Newtonian spin dipole (Lense-Thirring) and mass monopole (Schwarzschild) effects could be tested to a high accuracy depending on the level of compensation of the non-gravitational perturbations, not treated here. Moreover, the large eccentricity of the orbit would allow one to constrain several long-range modified models of gravity and accurately measure the gravitational red-shift as well. Each of the six Keplerian orbital elements could be individually monitored to extract the G J 2 / c 2 signature, or they could be suitably combined in order to disentangle the post-Newtonian effect(s) of interest from the competing mismodeled Newtonian secular precessions induced by the zonal harmonic multipoles J ℓ of the geopotential. In the latter case, the systematic uncertainty due to the current formal errors σ J ℓ of a recent global Earth’s gravity field model are better than 1 % for all the post-Newtonian effects considered, with a peak of ≃ 10 − 7 for the Schwarzschild-like shifts. Instead, the gravitomagnetic spin octupole precessions are too small to be detectable.

Published: July 2019

H9N2 avian influenza viruses have become globally widespread in poultry over the last two decades and represent a genuine threat both to the global poultry industry but also humans through their high rates of zoonotic infection and pandemic potential. H9N2 viruses are generally hyperendemic in affected countries and have been found in poultry in many new regions in recent years. In this review, we examine the current global spread of H9N2 avian influenza viruses as well as their host range, tropism, transmission routes and the risk posed by these viruses to human health.

Usually self-limited, hepatitis E virus (HEV) infection may evolve to chronicity and cirrhosis in immunosuppressed patients. HEV infection has been described in solid-organ transplantation and hematology patients, but for allogeneic hematopoietic stem cell transplant (alloHSCT) recipients, only small cohorts are available. This retrospective nationwide multi-center series aimed to describe HEV diagnostic practices in alloHSCT French centers, and the course of infection in the context of alloHSCT. Twenty-nine out of 37 centers participated. HEV search in case of liver function tests (LFT) abnormalities was never performed in 24% of centers, occasionally in 55%, and systematically in 21%. Twenty-five cases of active HEV infection were diagnosed in seven centers, all because of LFT abnormalities, by blood nucleic acid testing. HEV infection was diagnosed in three patients before alloHSCT; HEV infection did not influence transplantation planning, and resolved spontaneously before or after alloHSCT. Twenty-two patients were diagnosed a median of 283 days after alloHSCT. Nine patients (41%) had spontaneous viral clearance, mostly after immunosuppressive treatment decrease. Thirteen patients (59%) received ribavirin, with sustained viral clearance in 11/12 evaluable patients. We observed three HEV recurrences but no HEV-related death or liver failure, nor evolution to cirrhosis.

I analysed the collected data with scientifically established statistical methods.During studying resources I analysed the time factor from two aspects. On the one hand, I wanted to know what role time has in managers’ opinions in increasing company efficiency andperformance. On the other hand, I asked them how much they consider this resource to be expandable.
Contradiction in the agrofinancial regulation of agricultural producers
Authors: Szilágyi Bernadett
Published: July 2019

Hungary is a country of favourable conditions with agropotential, for this reason the regulations regarding agriculture is constantly the bone of legislative contention. Thepurpose of this study is to present the actual agropotential contradictions concerning the agricultural producers, specifically focusing on certain problems without any detailed representation of the valid rules of law. The agrofinancial anomalies referring to agricultural producers can be found mostly in the system of the personal income tax (allowance, tax immunity), the value added tax (special agricultural legal position) as well as the social insurance.The severity of the problem is supported by the agricultural producers’ behavioral types of paying taxes, globalisation process of these days and our place in the European Union. The resolution of the contradictions in agriculture does not lie by any means in the proper way of making the rules of the law of taxation, but in a comprehensive economic policy, which is to be waited for.

Characterising brines in deep Mesozoic sandstone reservoirs, Denmark
Authors: Holmslykke Hanne D. , Schovsbo Niels H. , Kristensen Lars , Weibel Rikke , Nielsen Lars Henrik
Published: July 2019

The Danish subsurface contains several sandstone units, which represent a large geothermal resource (Vosgerau et al. 2016). Currently, only three geothermal plants are operating in Denmark, but several exploration licences are expected to be awarded in 2019. Geothermal energy is exploited from deeply buried porous sandstones by bringing warm form­ation water (brine) to the surface, extracting the heat and returning the cooled water to the same sandstones. The reduced temperature of the brine during this process implies a risk of scaling, which may reduce reservoir permeability and hence injectivity. Predicting the chemical composition of formation waters, however, could help to reduce the risk associated with scaling in planned geothermal facilities.

Here, we present a regional overview of the geochem­istry of brines from deep Mesozoic sandstones in the Danish Basin and North German Basin that supplements previous studies, notably by Laier (2002, 2008). The brine composition at shallow burial typically reflects the original (connate) formation water chemistry, which is determined by the original depositional environment of the sandstone, for example fluvial or marine. However, the mineralogical composition of the sandstone changes during burial, whereby some minerals may dissolve or precipitate when exposed to higher temperatures. These mineral changes are reflected in the brine composition, which typically becomes more saline with increased burial (e.g. Laier 2008; Kharaka & Hanor 2003). 

The brine chemistry reported here shows a distinct depth trend, which reflects original connate formation waters that are modified through burial diagenesis. We have classified the brines into brine types, which are shown to be related to their depositional environment, depth, geological formation and geographical domains.
Application of Snail Shell Chitosan as a Bioadsorbent in Removal of Copper (II) Ions from Wastewater
Authors: Peter Oyekunle Ifeoluwa , Adeyinka Oyegoke Jamal , Akolade Raji Ahmed
Published: July 2019

Recently, various adsorbents have been employed in removing different heavy metals from wastewater particularly those that are toxic to man. This study was therefore conducted to examine the potency of chitosan obtained from snail shells to remove copper from wastewater by adsorption. The chitosan was subjected to Fourier transform infrared (FTIR) analysis which showed a strong band at 3425.69cm-1 that can be attributed to N-H and O-H stretching. The peak observed at 2939.61cm-1 indicated symmetric alkane -C-H stretching vibration or -OH stretch of carboxylic acids while that of 2546.12cm-1 can be assigned to -C≡C stretching vibration of alkynes. The presence of residual N acetyl group was confirmed by the peak at 1643.41cm-1 (C=O stretching of amide I) and the peak at 1489.10cm-1 may be attributed to glycosidic linkage. The absorption band at 1149.61cm-1 can be attributed to be asymmetric stretching of the C-O-C bridge. The adsorption of copper by the chitosan was also studied under the effects of some process parameters and it was observed that removal efficiency of the chitosan increased with increase in contact time, adsorbent dosage and pH but decreased with increase in initial metal concentration. The adsorption of the copper ions was found to be aided by the presence of amine functional group on the chitosan and the mechanism of adsorption was chemisorption as the equilibrium data obtained from the study fitted better into the Langmuir isotherm model.

Meis, Karaada ve Fener Adası, Yunanistan’ın Doğu Akdeniz’de geniş bir deniz yetki alanı iddiası için dayanak teşkil etmektedir. Yunanistan, bu adaları bir “grup” olarak nitelemek suretiyle deniz yetki sınırlandırmasında, tam etki göstermeleri gerektiğini iddia etmektedir. Türkiye ise sınırlandırma hukuku kurallarına dayanarak bu iddiayı kabul etmemektedir. Bu bağlamda, Meis, Karaada ve Fener Adası’nın münhasır ekonomik bölge ve kıta sahanlığı sınırlandırması açısından etki göstermemesi ve sadece karasuları ile yetinmesi gerekir. Söz konusu adaların etkisizliğini sağlamak üzere Türkiye’nin dayanabileceği bir başka kural, Birleşmiş Milletler Deniz Hukuku Sözleşmesi’nin 121/3. maddesidir. Gerçekten de eğer bu adalar bahsi geçen madde anlamında kaya statüsünde iseler zaten münhasır ekonomik bölge ve kıta sahanlığı üretemeyecekleri için bu alanların sınırlandırılmasında da etkisiz olacaklardır. Bu da Doğu Akdeniz’e ilişkin Türk tezlerine katkı sağlayan bir dayanak teşkil edecektir. Bu çalışmada, söz konusu adaların statüsü, Güney Çin Denizi Tahkiminde tespit edilen ölçütler bağlamında değerlendirilmiştir.
Kebutuhan Kedelai dan Kapasitas Produksi Tahu pada Pengrajin Tahu di Kabupaten Sumedang

Kedelai merupakan salah satu komoditi pokok masyarakat Indonesia. Hal ini dikarenakan kedelai merupakan bahan baku pembuatan tempe dan tahu yang telah menjadi menu sehari-hari masyarakat Indonesia pada umumnya. Pertanian adalah mata pencaharian utama penduduk Kabepaten Sumedang. Selain daerah ini terkenal dengan hasil padi, Sumedang penghasil palawija diantaranya kedelai yang banyak digunakan sebagai bahan baku tahu oleh sebagian besar penduduk Sumedang sebagai pengrajin tahu yang terdiri dari 232 pengrajin tahu. dari data Kabupaten Sumedang, kedelai dihasilkan pada 2 kecamatan, yaitu Kecamatan Jatigeude 309 ton dan Kecamatan Surian 233 ton, jumlah kedelai yang dihasilkan Kabupaten Sumedang adalah 542 ton, melihat kebutuhan kedelai pada pengrajin tahu per bulan 630.180 kg (630,18 ton), maka produksi kedelai di Sumedang tidak mencukupiuntuk memenuhi kebutuhan bahan baku tahu per bulan. Dari 26 Kecamatan di Kabupaten Sumedang, hanya 2 kecamatan daerah penghasil tanaman kedelai, disamping rendahnya daerah penghasil kedelai, kondisi seperti ini hampir terjadi diseluruh Indonesia, hal ini terjadi dari segi persaingan pasar, ternyata harga riil kedelai impor jauh lebih murah daripada kedelai dalam produksi dalam negeri. Selama harga kedelai impor rendah, maka arus impor akan semakin tinggi, sehingga harga kedelai produksi dalam negeri akan turun, hal ini menyebabkan petani enggan untuk menanam kedelai. Penurunan harga riil kedelai menjadi disinsentif yang menyebabkan terjadinya penurunan  areal kedelai.

Sebagian besar lahan di Indonesia mengandung bahan organik yang rendah (<1%), sehingga produktivitas lahan menjadi rendah. Produktivitas lahan yang rendah disebabkan rendahnya ketersediaan hara akibat peran mikroba tanah yang menguntungkan bagi tanaman menurun. Penambahan bahan organik dan penggunaan pupuk hayati merupakan usaha untuk meningkatkan produktivitas tanah dan tanaman. Mikoriza Arbuskula (MA) merupakan salah satu pupuk hayati yang dapat meningkatkan produktivitas tanah dan tanaman. Percobaan rumah kasa dilakukan dengan tujuanuntuk mempelajari efek takaran pupuk kompos disertai inokulasi mikoriza terhadap pertumbuhan,kolonisasi mikoriza dan hasil tanaman kedelai. Percobaan menggunakan Rancangan Acak kelompok berfola faktorial dengan dua faktor dan dua ulangan. Faktor pertama yaitu takaran kompos terdiri dari tanpa kompos, 10 ton ha-1, 20 ton ha-1 dan 30 ton ha-1, sedangkan faktor kedua  kedua yaitu takaran mikoriza terdiri atas tanpa mikoriza, 5 g, 10 g dan 15 g per lubang tanam. Hasil percobaan menunjukkan bahwa takaran kompos dan mikoriza memberikan efek yang berbeda terhadap jumlah polong, jumlah biji dan bobot biji kering per tanaman, tetapi tidak terhadap tinggi tanaman, jumlah daun dan jumlah nodula efektif per tanaman, nisbah pupus akar, kolonisasi mikoriza, dan bobot 10 butir. Hasil lebih tinggi diperoleh jika pemberian 30 ton ha-1 dan 20 ton ha-1 disertai dengan inokulan miroriza masing-masing 10 g dan 15 g per lubang tanam.

Suatu percobaan untuk mengetahui pengaruh inokulasi mikoriza vesikular arbuskular terhadap pertumbuhan benih panili di persemaian, telah dilakukan di Desa Jatimekar, Kecamatan Situraja, Kabupaten Sumedang. percobaan dilaksanakan dari bulan Juni 2010 sampai bulan Oktober 2010. Rancangan yang digunakan dalam percobaan ini adalah Rancangan Acak Kelompok (RAK) pola sederhana, dengan enam perlakuan takaran mikoriza dan diulang empat kali. Perlakuan tersebut adalah A= 0 g/tanaman, B= 10 g/tanaman, C= 20 g/tanaman, D= 30 g/tanaman, E= 40 g/tanaman, F= 50 g/tanaman. Hasil penelitian menunjukkan bahwa : (1) inokulasi mikoriza vesikular arbuskular berpengaruh terhadap pertumbuhan benih panili di persemaian; dan (2) pemberian inokulan mikoriza vesikular arbuskular pada takaran 40 dan 50 g per tanaman berpengaruh paling baik terhadap tinggi tanaman dan jumlah pasangan daun pada umur 12 MST dan 16 MST, serta bobot kering tunas pada umur 12 MST.
Reflections on the Life-Sustaining Treatment Decisions Act: A Medical Oncologist’s Perspective
Authors: AHN Heejoon
Published: July 2019

More than a year has passed since the implementation of the “Act on Decisions on Life-sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life” (hereafter the “Life-Sustaining Treatment Decisions Act”) in South Korea. Although there have been complaints about the complicated legal documents that the law requires patients to complete when choosing to end life-sustaining treatment, overall this new law has been well received and more patients than expected have made use of the provisions of this law since it was implemented. However, it is now time to reconsider whether the law is serving the purpose for which it was originally designed. I argue in this article that while the expressed purpose of the Life-Sustaining Treatment Decisions Act is to respect and enhance patient autonomy, in practice the law seems to do more to reduce socio-economic burden than to protect patient autonomy. Furthermore, this law is transforming the ethical culture within the practice of medicine into a bureaucracy. Greater public debate on this matter is needed to ensure that the Life-Sustaining Treatment Decisions Act serves the purpose for which it was originally designed.

A new Dasycladale is described as Dissocladella? chahtorshiana Rashidi & Schlagintweit n. sp. from Selandian carbonates of Mount Chah Torsh, Central Iran (type locality). Other occurrence is from the Sistan Suture Zone of Eastern Iran (Selandian?, Thanetian?). The medium-sized taxon displays cylindrical to slightly claviform thalli with a relatively large main axis bearing alternating primaries of variable shape. The latter show either slowly widening towards the distal end or are club-shaped displaying very short secondaries. The morphological variability of the primaries, both typical and atypical for Dissocladella, account for some doubts on the generic assignment of the new species. Dissocladella? chahtorshiana occurs in bioclastic packstones with Cymopolia mayaense Johnson & Kaska, Acroporella cf. anceps Segonzac, Halimeda sp., and benthic foraminifera (e.g., soritiids) at its type locality.

This study examines the costs and household-level benefits of overseas migration in Toba Tek Singh, Pakistan. A household survey was conducted to assess the transaction costs associated with the transfer of remittances and the sources used to finance overseas migration. We also carry out a propensity-score matching exercise, which reveals that overseas migration has substantial benefits as measured by migrants’ consumption levels, their expenditures on health, education, and vehicles, and the level of household savings. Policy options to facilitate migration and the transfer of remittances include (i) establishing technical training institutions to help workers upgrade their skills, (ii) information campaigns on the migration process and opportunities available, (iii) setting up institutions to provide loans for potential migrants, (iv) reducing money transfer costs through formal channels, and (v) building awareness of the Pakistan Remittance Initiative.
Relative Factor Abundance and Relative Factor Price Equality in Punjab
Authors: Naveed Resham
Published: July 2019

This study tests the relative factor price equality across districts in Punjab using the methodology developed by Bernard, Redding, and Schott (2009) and data from the Census of Manufacturing Industries for 2000/01 and 2005/06. The results indicate the absence of relative factor price equalization due to the uneven distribution of factors in the province. Nonproduction (white-collar) workers) are relatively scarce in Punjab, which results in a wage premium for this type of labor. The study adjusts for worker quality by using a Mincerian wage equation as worker quality could explain the wage differential between white-collar and blue-collar workers. However, this exercise yields similar results, implying that factors are distributed unevenly across the districts of Punjab even after controlling for worker quality differences.
An RCA Analysis of Textiles and Clothing in Pakistan, India, and Bangladesh
Authors: Shahzad Khurram
Published: July 2019

This study focuses on the revealed comparative advantage analysis for Clothing and Textile sectors of Pakistan, India and Bangladesh. We have applied the Balassa’s (1965) Index for the analysis. The revealed comparative advantage has been analyzed in two different ways: one static on the year 2010 and the other one dynamic based on 1980, 1990, 2000 and 2010. For the dynamic analysis, the average of the three previous years from 2010 were taken and used for revealed comparative advantage. The results show Pakistan’s highest revealed comparative advantage for textiles over both India and Bangladesh. India has revealed a comparative disadvantage in textile in competition of Pakistan and Bangladesh. For clothing, Bangladesh has very dominant revealed comparative advantage when competing with Pakistan and India. Dynamic revealed comparative advantage indicates Pakistan has been gaining a comparative advantage in textiles since 1980 but with a declining percentage of textile export. Bangladesh has significantly gained a comparative advantage in clothing since the 1980s.
