Authors: Omar Wan Adnan Wan , Yahaya Noorfatimah , Ghaffar Zainab Abdul , Fadzilah Nurdianah Harif
Published: January 2019

The pollen of stingless bees is derived from flower pollen mixed with bee digestive enzymes and preserved with honey and nectar. In this study, the volatile compounds present in ethanolic bee pollen extracts (BPEs) from three species of the Malaysian stingless bee were analyzed using gas chromatography-mass spectrometry (GC-MS). Hydrocarbons, sugars and its derivatives, fatty acids, amino acids, alcohol, uridine, aldehyde and an unknown carbamate were detected. Mannitol, the main sugar compounds, represented 54.34% in Trigona thoracica, 39.11% in Trigona apicalis and 33.05% in Trigona itama. Propanoic acid and hexadecanoic acid were the main hydrocarbons present in the extract of Trigona apicalis (4.04%) and Trigona thoracica pollen (1.28%) respectively. The polyunsaturated fatty acids linoleic acid and α-linolenic acid were found in small amounts in all BPEs (0.07-1.11%). The chemical compounds found in BPEs had biological activities, thus bee pollen may be useful in traditional medicine and as a health supplement.
How modernization encounter tradition: Iranian housing development in the Second Pahlavi period in Tehran (1940-1970)
Authors: Jafarbegloo Maryam
Published: January 2019

Iranian domestic tradition such as privacy and hospitality plays a significant role in shaping the Iranian traditional housing. However, studies on modern architecture have rarely focused on the house architecture, which has been adapted based on domestic tradition. The aim of this study is to understand how some features of local traditions, like privacy and hospitality, influenced housing development during the modernization period in Tehran. To this end, through a qualitative approach and data collection methods, this study identifies traditional values in modern housing. By categorizing the new house typology into detached houses, row houses, and high-rise apartments, the study discovers how architecture enables the consideration of privacy and hospitality in the physical form of modern houses. As a result, the new organization partly belonged to the traditional architecture and partly became unique as an Iranian modern house.
Management of mechanism design as an important way to improve public health
Authors: Sukharevа I.
Published: January 2019

One of the most important developments of modern economics is the concept of economic mechanism design. Mechanism design is the study of economic mechanisms that produce behaviors in public health. The concept has profound implications for management. Management involves the effective use of mechanisms to change behavior. Public health managers must have a strong background in sociology and psychology, negotiation, finance, economics, organizational theory, and leadership. All managers work with limited resources. Managers must understand finance and economics: budgets, investment in the Health Care system, accountability, investment return, optimization, and decision analysis. This feature creates unique challenges for educating and supporting public health managers. To advance public health management as a profession we must apply the basics of mechanism design to its challenges. Leadership science provides a base for development of managers’ personal skills and attributes. Many graduate programs in business management and public administration deal with public health management. Accordingly, application of mechanism design (economic, social and others) in public health management can help managers become more effective. Mechanism design in public health management could provide an important way to improve health of the population.

Published: January 2019

An access to adequate and safe blood transfusion services is an essential measure of basic healthcare systems. The main purpose of hemovigilance is to enhance the quality and safety of the blood transfusion chains, which are implemented for improving the quality of the blood transfusion chain processes, especially focusing on blood safety. Globally, the framework of hemovigilance is extending as one of the key escalations to the group of the human services administrations, recognizing restructured blood transfusions administrations.

The core objective of this review article is to highlight the objectives of the hemovigilance framework, historical aspects of the hemovigilance framework around the world and the scenario of Nepal. Furthermore, it likewise features the scopes and strategies for implementation of hemovigilance at a hospital. An acceptance and incorporation of the hemovigilance system in an oncology hospital or in any tertiary care hospitals in Nepal can avert the incidence or reappearance of adverse events due to the transfusion identified with the whole transfusion chain process. Globally, including the least developed country like Nepal, the hemovigilance framework must be incorporated and systematized for upgrading transfusion and general society certainty additionally regarding blood and its products. Different strategies must be made for the successful implementation and strengthening the hemovigilance system.

In conclusion, there is an interminable and endless necessity for the effort on hemovigilance; although the rules, regulations, and tools are in place. With the end goal to have a productive hemovigilance framework in the least developed countries like Nepal, an extensive methodology and enormous ideas are required.
Baptists, Fifth Monarchists, and the Reign of King Jesus
Authors: Birch Ian
Published: January 2019

This article outlines the rise of the Fifth Monarchists, a religiously inspired and politically motivated movement which came to prominence in the 1650s and believed the execution of Charles I cleared the way for King Jesus to return and reign with the saints from the throne of England. The imminent establishment of the Kingdom of Christ on earth was of great interest to Baptists, some of whom were initially drawn to the Fifth Monarchy cause because Fifth Monarchy theology provided a political route to a reformed society in England. While Baptists in the 1650s greatly desired to advance the cause of King Jesus the increasingly revolutionary methods employed by the Fifth Monarchists were at odds with their understanding of the spiritual nature of Christ’s kingdom, thus exposing differences in their respective eschatologies. Finally, observing the ambitious zeal of the Fifth Monarchist programme Baptists disavowed the anarchic revolutionary approach and distanced themselves from the movement. This breach, regarded as apostasy by the Fifth Monarchists, came at a fortunate time for the Baptist cause before the revolution was stamped out and the leaders arrested. The rise and fall of the Fifth Monarchists, however, helped Baptists to clarify the nature and methods of their approach to establishing the kingdom of Christ among the saints on earth, and is therefore worthy of consideration for those wishing to understand the beginning of the Baptists in England and the nature of apocalyptic during the interregnum.
’The Struggle for Spiritual Values’: Scottish Baptists and the Second World War
Authors: Talbot Brian
Published: January 2019

The Secord World War was a conflict which many British people feared might happen, but they strongly supported the efforts of Prime Minister Neville Chamberlain to seek a peaceful resolution of tensions with Germany over disputes in Continental Europe. Baptists in Scotland shared these concerns of their fellow citizens, but equally supported the declaration of war in 1939 after the German invasion of Poland. They saw the conflict as a struggle for spiritual values and were as concerned about winning the peace that followed as well as the war. During the years 1939 to 1945 they recommitted themselves to sharing the Christian message with their fellow citizens and engaged in varied forms of evangelism and extended times of prayer for the nation. The success of their Armed Forces Chaplains in World War One ensured that Scottish Baptist padres had greater opportunities for service a generation later. Scottish Baptists had seen closer ties established with other churches in their country under the auspices of the Scottish Churches Council. This co-operation in the context of planning for helping refugees and engaging in reconstruction at the conclusion of the war led to proposals for a World Council of Churches. Scottish Baptists were more cautious about this extension of ecumenical relationships. In line with other Scottish Churches they recognised a weakening of Christian commitment in the wider nation, but were committed to the challenge of proclaiming their faith at this time. They had both high hopes and expectations for the post-war years in Scotland.

Published: January 2019

We investigated the gantry-angle classifier performance with a fluence map using three machine-learning algorithms, and compared it with human performance. Eighty prostate cases were investigated using a seven-field-intensity modulated radiotherapy treatment (IMRT) plan with beam angles of 0°, 50°, 100°, 155°, 205°, 260°, and 310°. The k-nearest neighbor (k-NN), logistic regression (LR), and support vector machine (SVM) algorithms were used. In the observer test, three radiotherapists assessed the gantry angle classification in a blind manner. The precision and recall rates were calculated for the machine learning and observer test. The average precision rate of the k-NN and LR algorithms were 94.8% and 97.9%, respectively. The average recall rate of the k-NN and LR algorithms were 94.3% and 97.9%, respectively. The SVM had 100% precision and recall rates. The gantry angles of 0°, 155°, and 205° had an accuracy of 100% in all algorithms. In the observer test, average precision and recall rates were 82.6% and 82.6%, respectively. All observers could easily classify the gantry angles of 0°, 155°, and 205° with a high degree of accuracy. Misclassifications occurred in gantry angles of 50°, 100°, 260°, and 310°. Machine learning could better classify gantry angles for prostate IMRT than human beings. In particular, the SVM algorithm had a perfect classification of 100%.
From Pre-Grammaticality to Proficiency in L1: Acquiring and Developing Infinitival Usage in Hebrew
Authors: Berman Ruth A.
Published: January 2019

The study traces the developmental route in acquisition and use of infinitives (e.g., lišon ‘to sleep’, le-exol ‘to-eat’, la-asot ’to-do’) in Hebrew as a first language, proceeding from the initial, “pre-grammatical“ emergence of linguistic forms among toddlers to structure-based knowledge and proficient use of the same devices in adolescence. Analysis involves a varied data-base of L1 oral Hebrew usage in: parent-child interactions of children aged 1;6 to 3;0 years; elicited storybook-based narratives of preschoolers; and personal-experience narratives and expository talks of schoolchildren, adolescents, and adults. Findings show that infinitives constitute an interesting test-case for examining the route from initial emergence via acquisition to maturely proficient command of a given subsystem in L1. Infinitival structures in Modern Hebrew, a language with an impoverished system of nonfinite verbs and lacking in auxiliaries of the kind common in Standard Average European, reveal a long developmental path, showing increasing complexity at all levels of language use: morphological form, types of syntactic constructions, semantic content, and discursive function, the latter primarily for the purpose of achieving textual connectivity.
Small Scale Poultry Farmers’ Choice of Adaption Strategies to Climate Change in Ogun State, Nigeria
Authors: Adepoju Abimbola O. , Osunbor Precious P.
Published: January 2019

Climate risks constitute an enormous challenge to poultry production and have affected the livelihoods of the people who depend on them. Thus, farmers have adopted various strategies that can help them cope with the adverse effects of climate change. The aim of this study is to examine the factors influencing small scale poultry farmers’ choice of adaptation strategies to climate change. Data used for this study were obtained from 121 representative farmers selected through a two-stage random sampling procedure. Descriptive Statistics, Likert Scale and the Multinomial Logit Model were the tools used for analysis. Results showed that the mean age and household size of the respondents were 45 years and 5 persons respectively, while the average number of birds per farmer stood at 583 birds. Majority of the respondents had a moderate perception of the impacts of climate change on poultry farming and chose management adaptation strategies in their fight against climate change. Econometric analysis showed that the age, gender and educational status of farmers, number of birds, household size, poultry experience, access to cooperative societies, poultry housing system, access to credit, access to extension services and farm size were the factors influencing farmers’ choice of climate change adaptation strategies in the study area. Therefore, policy should focus on awareness creation on management adaptation strategies through enhancing education and extension services as well as access of poultry farmers to credit facilities to indirectly insure farmers against climate change impacts.

Published: January 2019

Human capital development is increasingly gaining policy relevance especially with the implementation of the Sustainable Development Goals (SDGs). This study examined the correlates of human capital expenditure in rural Nigeria. General Household Survey dataset collected by the National Bureau of Statistics was used for this study. Descriptive statistical tools, principal components analysis and the Heckman selection model were used to analyse relevant data. The study found majority of the households were male-headed, with an average size of 7 people. In terms of access to education, 62.1% of the surveyed households had access to education and spent an average of NGN 12,570.56 on education. The age of household head, access to loans, marital status and household size were the correlates of human capital expenditure in rural Nigeria. Also, school fees and registration accounted for 41.2% of households’ expenditure on education. The study found paucity of funds, low priority placed on education and low interest were the main constraints to human capital expenditure. The study recommended the design and implementation of pro-poor educational interventions especially for children from rural households. Also, there is the need for government, multilateral organisations and financial institutions to position rural households for financial inclusion.
RON-Gauss: Enhancing Utility in Non-Interactive Private Data Release
Authors: Chanyaswad Thee , Liu Changchang , Mittal Prateek
Published: January 2019

A key challenge facing the design of differential privacy in the non-interactive setting is to maintain the utility of the released data. To overcome this challenge, we utilize theDiaconis-Freedman-Meckes (DFM) effect, which states that most projections of high-dimensional data are nearly Gaussian. Hence, we propose theRON-Gaussmodel that leverages the novel combination of dimensionality reduction via random orthonormal (RON) projection and the Gaussian generative model for synthesizing differentially-private data. We analyze how RON-Gauss benefits from the DFM effect, and present multiple algorithms for a range of machine learning applications, including both unsupervised and supervised learning. Furthermore, we rigorously prove that (a) our algorithms satisfy the strongɛ-differential privacy guarantee, and (b) RON projection can lower the level of perturbation required for differential privacy. Finally, we illustrate the effectiveness of RON-Gauss under three common machine learning applications – clustering, classification, and regression – on three large real-world datasets. Our empirical results show that (a) RON-Gauss outperforms previous approaches by up to an order of magnitude, and (b) loss in utility compared to the non-private real data is small. Thus, RON-Gauss can serve as a key enabler for real-world deployment of privacy-preserving data release.
Systematizing Genome Privacy Research: A Privacy-Enhancing Technologies Perspective

Published: January 2019

Rapid advances in human genomics are enabling researchers to gain a better understanding of the role of the genome in our health and well-being, stimulating hope for more effective and cost efficient healthcare. However, this also prompts a number of security and privacy concerns stemming from the distinctive characteristics of genomic data. To address them, a new research community has emerged and produced a large number of publications and initiatives. In this paper, we rely on a structured methodology to contextualize and provide a critical analysis of the current knowledge on privacy-enhancing technologies used for testing, storing, and sharing genomic data, using a representative sample of the work published in the past decade. We identify and discuss limitations, technical challenges, and issues faced by the community, focusing in particular on those that are inherently tied to the nature of the problem and are harder for the community alone to address. Finally, we report on the importance and difficulty of the identified challenges based on an online survey of genome data privacy experts.
PD-DM: An efficient locality-preserving block device mapper with plausible deniability
Authors: Chen Chen , Chakraborti Anrin , Sion Radu
Published: January 2019

Encryption protects sensitive data from unauthorized access, yet is not sufficient when users are forced to surrender keys under duress. In contrast, plausible deniability enables users to not only encrypt data but also deny its existence when challenged. Most existing plausible deniability work (e.g. the successful and unfortunately now-defunct TrueCrypt) tackles “single snapshot” adversaries, and cannot handle the more realistic scenario of adversaries gaining access to a device at multiple time points. Such “multi-snapshot” adversaries can simply observe modifications between snapshots and detect the existence of hidden data. Existing ideas handling “multi-snapshot” scenarios feature prohibitive overheads when deployed on practically-sized disks. This is mostly due to a lack of data locality inherent in certain standard access-randomization mechanisms, one of the building blocks used to ensure plausible deniability.

In this work, we show that such randomization is not necessary for strong plausible deniability. Instead, it can be replaced by a canonical form that permits most of writes to be done sequentially. This has two key advantages: 1) it reduces the impact of seek due to random accesses; 2) it reduces the overall number of physical blocks that need to be written for each logical write. As a result, PD-DM increases I/O throughput by orders of magnitude (10–100× in typical setups) over existing work while maintaining strong plausible deniability against multi-snapshot adversaries.

Notably, PD-DM is the first plausible-deniable system getting within reach of the performance of standard encrypted volumes (dm-crypt) for random I/O.
Hardware-Supported ORAM in Effect: Practical Oblivious Search and Update on Very Large Dataset
Authors: Hoang Thang , Ozmen Muslum Ozgur , Jang Yeongjin , Yavuz Attila A.
Published: January 2019

The ability to query and update over encrypted data is an essential feature to enable breach-resilient cyber-infrastructures. Statistical attacks on searchable encryption (SE) have demonstrated the importance of sealing information leaks in access patterns. In response to such attacks, the community has proposed the Oblivious Random Access Machine (ORAM). However, due to the logarithmic communication overhead of ORAM, the composition of ORAM and SE is known to be costly in the conventional client-server model, which poses a critical barrier toward its practical adaptations.

In this paper, we propose a novel hardware-supported privacy-enhancing platform called Practical Oblivious Search and Update Platform (POSUP), which enables oblivious keyword search and update operations on large datasets with high efficiency. We harness Intel SGX to realize efficient oblivious data structures for oblivious search/update purposes. We implemented POSUP and evaluated its performance on a Wikipedia dataset containing ≥229 keyword-file pairs. Our implementation is highly efficient, taking only 1 ms to access a 3 KB block with Circuit-ORAM. Our experiments have shown that POSUP offers up to 70× less end-to-end delay with 100× reduced network bandwidth consumption compared with the traditional ORAM-SE composition without secure hardware. POSUP is also at least 4.5× faster for up to 99.5% of keywords that can be searched compared with state-of-the-art Intel SGX-assisted search platforms.
Experimental determination of the kinetics of sorption and gas filtration in coal
Authors: Gawor Marek
Published: January 2019

The paper presents tests set-ups for experiments on sorption kinetics and gas filtration kinetics in a porous medium. It was observed that two phenomena occur in these processes: transportation of gas into the porous solid and settling of gas molecules on the walls of the solid or within its volume. An experiment was carried out in which a thin resistance thermometer was quickly taken out of an argon stream and placed in carbon dioxide or the other way round. The measurement made it possible to determine the sorption time constant. It was demonstrated that the sorption rate is much higher than the filtration rate. Thus, filtration is the process describing the rate at which gas molecules penetrating the porous substance are adsorbed or desorbed. The sorption time constant is not >50 m.

In the second experiment, the author determined the rate at which gas is liberated from coal grains. The measurement method was based on measurement of the pressure of desorbing gas in constant volume. The experiment involved measurement of the pressure of the gas liberated from the coal grains in a closed chamber. The kinetic curves obtained in this way were used to determine the carbon dioxide coefficient in coal grains. During the experiment, particular focus was put on the initial stage of gas liberation (up to 0.4 s).

The slower process of gas transporting in the porous structure of coal is the transporting of gas through a coal briquette. Experimentally implemented variety of boundary conditions allowed for a more complete verification of the assumed theoretical model and possibly for the exact determination of filtration parameters. The experimental set-up built for this purpose, allows for pressure and temperature measurement on the briquette side surface.
Low-Strength Substrates and Anthropogenic Soils in Transportation Engineering
Authors: Batog Andrzej , Stilger-Szydło Elżbieta
Published: January 2019

Road embankments, especially their slopes’ surfaces, must fulfil all the requirements concerning the exploitation criteria after the completion of construction works. This is very important while constructing or modernizing the embankments, based on the substrate including low-strength soils as well as in simple ground conditions (most convenient). The last dozen or so years of intensive construction of transport infrastructure have shown how big is the problem of ensuring the required volumes of qualified soil material for the construction of road embankments or the modernization of railway embankments. The depleting deposits of natural and easily accessible soils for the construction of embankments result in the need to use anthropogenic soils, for example, in the form of aggregates from the recycling of construction waste and other locally available waste materials, usually in the form of slag and ashes from the combined heat and power plants. In such cases, there’s a need to treat transportation earth structures individually in the scope of designing and quality control, because there are no applicable standard provisions in this scope.

This work indicates some of these important contemporary problems of transport engineering, occurring in newly built and modernized road objects, such as the stability of road embankments based on a low-strength substrate, use of anthropogenic soils and materials originating from the recycling of concrete surfaces for the construction of road embankments.

Numerical evaluation of the interpolation accuracy of simple elementary functions
Authors: Znamenskij Sergej Vital'evich
Published: January 2019

The paper contains a comparison of the accuracy of the restoration of elementary functions by the values in the nodes for algorithms of low-degree piecewise-polynomial interpolation. The test results demonstrate in graphical form the advantages and disadvantages of the widely used cubic interpolation splines.

The comparison revealed that, contrary to popular belief, the smoothness of the interpolant is not directly related to the accuracy of the approximation. In the 20 different examples considered, the piecewise quadratic interpolation is rarely and only slightly inferior in the form of the used classical cubic splines, often by orders of magnitude better than many of them.

In several examples, the high interpolation error of simple functions on a fixed grid appears to be almost independent of the degree of the algorithm and the smoothness of the interpolant. The piecewise-linear interpolation unexpectedly appeared the most accurate in one of the examples.

A new problem arises: to find a local interpolation algorithm, accurately restoring any rational functions of the second order.

Family support covered informational support, instrumental support, emotional support, and appraisal support needed tuberculosis patients, including support of nutrition fulfillment.Â  The study aimed to know the correlation of information obtained and the family support to the fulfillment of nutrition of tuberculosis patients. The study used correlation design. The sample was the family of tuberculosis patient of first category who was registered to Public Health Center of Blitar city. The sample was 44 respondents selected by simple random sampling. The data collection used the close-ended questionnaire that was developed based on the theory of social support. The result showed that families who had ever received information about nutrition fulfillment was 11.4% (5 families) and had not ever received information was 88.6% (39 families); and the family support to the fulfillment of nutrition of tuberculosis patients of first category was in the category of supportive (59.1%) and non-supportive family was 40.9% (18 families). The correlation value of the Kendall Tau-b was 0.298 (p = 0.014). The family support for the fulfillment of nutrition of tuberculosis patients of first category who support was caused by the information obtained, while who did not support was caused by lack of information about the importance of nutrition fulfillment of tuberculosis patient. A weak correlation was caused by families who had received information about nutrition fulfillment for tuberculosis patients was very little, consequently the support given by the patient as a reward as a family member who was sick was also little. It is recommended that health workers at the Public Health Center give of health education regularly to the family in every drug taking.

Published: January 2019

The occurrence of keyhole porosity in selective laser melting (SLM) has so far not been quantified systematically using X-ray computed tomography (X-CT). In this study, keyhole porosity in selective laser molten Ti-6Al-4V grade 23 parts was analyzed using post-process characterizations. Single tracks were produced with optimum, high volumetric energy density and low volumetric energy density parameters on the top of SLM substrate. High volumetric energy density was achieved by either (i) high laser power and optimum scan speed to study the effect of laser power or (ii) optimum laser power and low scan speed to study the effect of scan speed. Keyhole porosity is sensitive to the SLM process parameters. It was observed by using X-CT that a high amount of keyhole porosity was formed below the line scan produced with a high volumetric energy density achieved by optimum laser power and low scan speed; however, a line scan produced with same volumetric energy density but achieved by high laser power and optimum scan speed resulted in less or no voids. The X-CT porosity analysis helped to understand the size, shape, location, and number of keyhole pores that were formed.

Telah dilakukan pengamatan awan di DAS Mamasa berdasarkan data X-band Mobile Radar untuk mengetahui karakteristik pertumbuhan awan di daerah tersebut. Pengamatan awan dilakukan pada saat kegiatan penyemaian awan tangal 21 Oktober - 19 November 2009. Hasil pengamatan menunjukkan bahwa pertumbuhan awan di DAS Mamasa dipengaruhi oleh proses orografik dan arah angin. Pada saat angin baratan, pertumbuhan awan terkonsentrasi di sisi bagian barat DAS Mamasa. Sebaliknya, pertumbuhan awan terkonsentrasi di sisi bagian timur DAS Mamasa ketika terjadi angin timuran.Study on the characteristic of cloud development at Mamasa catchment area is very important since the water supply for Bakaru hydro-electric power is highly depend on the rain fall over this area. During rain enhancement project on 21 October to 19 November 2009, convective clouds have been analized based on X-band mobile weather radar observation over Mamasa River catchment area. The observation result shows that cloud development in this area are influenced by orographic processes and wind direction. During westerly wind, the clouds developed over the western part of catchment area. On the contrary, the clouds were observed over the east side of cathment area during easterly wind.

Published: January 2019

Estimasi evaporasi di daerah waduk menggunakan metode empiris dengan input data satelit dilakukan untuk mengatasi masalah ketersediaan data meteorologi dari observasi permukaan. Data satelit berupa Land Surface Temperature dari satelit Himawari dan profil atmosfer dari satelit MODIS digunakan untuk memperoleh informasi parameter temperatur, kelembapan relatif dan radiasi matahari untuk mengestimasi besaran evaporasi di daerah waduk. Metode empiris yang digunakan antara lain adalah Blaney-Criddle, Kharuffa, Hargreaves, Schendel dan Schendel yang dimodifikasi (Modified Schendel). Hasil estimasi evaporasi dibandingkan terhadap evaporasi acuan yang dihitung menggunakan metode kombinasi (Penman) dengan input parameter meteorologi hasil observasi. Observasi dilakukan menggunakan Automatic Weather Station di dua titik pengamatan di Waduk Saguling. Hasil penelitian menunjukkan estimasi evaporasi waduk dengan input data satelit dapat dilakukan dengan metode yang ada namun diperlukan modifikasi. Metode estimasi evaporasi waduk yang terbaik adalah Modified Schendel, namun belum bisa menunjukkan variasi spasial yang sesuai observasi. Penggunaan regresi Linier Berganda dan menambahkan parameter radiasi matahari pada Modified Schendel, didapatkan suatu persamaan yang baik secara statistik dan dapat menunjukkan variasi spasial evaporasi di Waduk Saguling yang sesuai observasi.
