Published: December 2018

Based on statistical data, it is known that Android is the most popular smartphone with the largest number of users in the world, which is about 1.8 billion users. The high number of users also invite the many cases of information security and privacy caused by the lack of awareness of the user such as : spam, spoofing/phising, network incident, malware, uploading something personal data such as photos, phone numbers, addresses or having no antivirus. This study aims to find out about the awareness of the security of information and privacy of Android smartphone users by doing measurement of problem. The awareness has some dimensions such as attitude, knowledge and behavior with the seven focus areas of information security namely trust in app repository, misconception about app testing, security and agreement message, pirated application, adoption Security control, spam sms and report of security incidents and three focus areas of privacy are perceived surveillance, perceived intrusion, secondary use of information. This research uses analytical hierarchy process (AHP) to measure the level of awareness of information security and privacy of smartphone users. Overall, the results of the research show that information security has an average level of awareness (71%) but the focus area of report for security incidents has a poor level of awareness (37%) this occur because users prefer to solve their own information security issues experienced and privacy has an average level of awareness (76%). However, for secondary use of information in attitude dimension has low awareness level (66%). Based on the results of this study, it can be concluded that smartphone users in Indonesia have a poor awareness level in maintaining security and privacy of their information.

An innovative approach to creating a new generation of specialised foods for dietary therapy of type
2 diabetes can involve planned adding of plant polyphenols to their formulafions. The marked antioxidant properties of polyphenols largely determine their potential antidiabetic effects. However, the use of food polyphenols for prophylactic purposes is limited by their low bioavailability, which makes it expedient to search for technological approaches aimed at obtaining polyphenolic matrices with high biological activity, increased digestibility, and stability. This study objective was to purposely extract and concentrate the polyphenols by sorbing them from an aqueous solution of the bilberry leaf extract (BLE) on buckwheat flour and to assess their storage stability. A number of experiments on optimal parameters selection for sorbing polyphenols from the BLE on buckwheat flour were performed. The parameters included the concentration of the extract solution, the solution/sorbent ratio, the pH of the solution, the temperature and the time of sorption. The sorption on the polyphenol matrix was determined from the difference in their contents in the initial solution of the extract and in the supernatant after centrifugation by the Folin-Ciocalteu method. The effects of exposure to light, temperatures, and humidity on the polyphenol compounds in the dry BLE and in the food matrix contents during storage was analysed by the FTIR spectroscopy. The experiments determined the optimal conditions for the BLE polyphenol sorption on buckwheat flour by incubation of a 2% BLE solution pH = 3.6 with the portion of buckwheat flour at the ratio of 1g/50 cm3 solution for 45 minutes at 25°C. When storing the food matrix, there was no significant degradation of the polyphenolic compounds in the food matrix, which indicates an increase in the stability of the polyphenols sorbed on buckwheat flour. This paper presents the results that are scientifically and practically relevant for the nutritiology experts who devise promising technological approaches to expanding the range of functional food ingredients of the antidiabetic character.
Analysis of water quality characteristic for water distribution systems
Authors: Wang Yumin , Zhu Guangcan , Yang Zhonglian 
Published: December 2018

Abstract
Since governments all over the world are paying more attention to water quality in water distribution systems (WDS), a method based on mass balance and first-order chlorine decay model was proposed to assess the efficiency of WDS involving water quality (represented by residual chlorine). The concepts of surplus chlorine factor (S) for nodes in individual pipes and comprehensive surplus chlorine factor (CS) for nodes in WDS were put forward to represent the water quality characteristic of nodes in WDS based on the assumption that the structure of the pipe network and quantity of chlorine dose are definite. The proposed method was applied to two examples of WDS and sensitivity analysis regarding chlorine decay coefficient (k0) was discussed. The results indicated that values of CS for nodes in WDS are affected by the inflow of nodes, which is determined by water demand and pipe length from water sources to nodes. In addition, the value of CS increases with k0 when the inflow of the node is larger than the optimized inflow. The results verified that the deduction of S for a single pipe can be generalized to WDS, and can measure the water quality characteristics for nodes in WDS easily.
The resistance effect of vegetation stem diameter on overland runoff under different slope gradients
Authors: Zhang Shengtang , Zhang Jingzhou , Liu Yin , Liu Yuanchen , Li Guibao 
Published: December 2018

AbstractVegetation is an important part of the natural environment and has resistance effects on overland runoff, which can effectively reduce hydraulic erosion. The effect of vegetation stem diameter and slope gradient on flow resistance is thus worthy of further study. The influence of three different slope gradients (s), three vegetation stem diameters (d) and 12 levels of unit discharge (q) on the flow resistance of a slope was simulated to systematically study the effect of vegetation stem diameter and slope gradient on overland runoff. The diameter of the vegetation stem and the slope gradient were found to have a significant resistance effect on overland runoff. Under the same slope gradient, the Darcy–Weisbach resistance factor (f) increased with an increase in the vegetation stem diameter. Under experimental conditions, the rate of change of f was analysed by linear regression, and as d increased by 1 mm, f increased by an average of 49.9%. For a given vegetation stem diameter and vegetation distribution pattern, the greater the slope gradient, the smaller the value of f, and as S increased by 1.0%, f decreased by an average of 24.5%. These results are important to optimize the slope vegetation distribution in farmland conservation.
On Graph theoretic index of Complementary Benzenoids And Macromolecules
Authors: Senbagamalar Jaishankar 
Published: December 2018

Background:
A topological index of a graph G is a numerical parameter related to G
which characterizes its molecular topology. In the field of QSAR and QSPR research, theoretical
properties of the chemical compounds and their molecular topological indices such as distance
connectivity indices and degree connectivity indices are used to predict the bioactivity of different
molecular compounds.

Materials and Methods:
Such an approach is different from the traditional QSAR methodology,
where one employs selected simpler physico-chemical properties to predict biological activities of
molecules. In order to obtain the structure-activity relationships in which theoretical and computational
methods are necessary to find appropriate representations of the molecular structure of
chemical compounds. These representations are realized through the molecular descriptors. Molecular
descriptors are numbers containing structural information derived from the structural representation
used for molecules under study.

Results:
A topological index defined on molecular structure G can be considered as a real valued
function
f :G→ R+ which maps each durg molecular structure to certain real numbers. Graphene
sheets are composed of carbon atoms linked in hexagonal shapes with each carbon atom covalently
bonded to three other carbon atoms. Each sheet of graphene is only one atom thick and each
graphene sheet is considered a single molecule. Graphene has the same structure of carbon atoms
linked in hexagonal shapes to form carbon nanotubes, but graphene is flat rather than cylindrical..
This paper addresses the problem of computing the Wiener , First Zagreb index and Forgotten index
of Complementary graphs of graphene sheets, triangular benzenoid graph, circumcoronene
molecular graph and nanostar dendrimers.

Conclusion:
The line graphs were used for modeling amino acid sequences of proteins and of the
genetic code. The connected graphs are isomorphic to self complementary graphs. Recently, molecular
graphs have proved to be highly useful for drugs activity. Non empirical parameters of
chemical structures derived from graph theoretic formalisms are being widely used by many researchers
in studies pertaining to molecular design, pharmaceutical drug-design, and environmental
hazard assessment of chemicals.
Developmental Studies of Curcumin NLCs as Safe Alternative in Management of Infectious Childhood Dermatitis
Authors: Lalan Manisha , Shah Pranav , Shah Krina , Prasad Aparna 
Published: December 2018

Objective:
The objective of the present studies was to develop and evaluate curcumin loaded
NLCs for management of childhood dermatitis by exploiting its antimicrobial and anti-infective properties
and increasing its skin deposition.

Methods:
The screened lipidic excipients (on solubility basis) were used to formulate NLC dispersion by
solvent injection technique and process variables were optimized. Central composite design was employed
to study the effect of surfactant, total lipid and ratio of solid lipid to liquid lipid on dependent variables
such as particle size, zeta potential, % entrapment efficiency and time for 80% drug release. Curcumin
NLCs were incorporated into carbopol 934 P based gel and characterized for morphological and rheological
properties, drug release, skin permeation and retention study, skin irritancy, in vitro microbial
activity and stability.

Results:
The optimized formulations exhibited satisfactory physicochemical properties and followed
Higuchi kinetic model. The NLC dispersion when incorporated into gel, was stable and nonirritating. Antimicrobial
study against S. aureus showed larger zone of inhibition with developed formulation. Statistical
model indicated that higher surfactant concentrations, lower lipid concentrations, reducing the solid lipid content
minimized the particle size, maximized the % entrapment efficiency and optimized time for 80% drug release,
while it had an inverse effect on zeta potential. The TEM of NLC dispersions elucidated its sphericity.

Conclusion:
The developed curcumin NLC gel exhibited potential in management of childhood dermatitis
by virtue of sustained drug release, increase skin deposition and efficient antimicrobial action.
Metal Nanoparticles: An Efficient Tool for Heterocycles Synthesis and Their Functionalization via C-H Activation
Authors: Saha Debasree , Mukhopadhyay Chhanda 
Published: December 2018

Background:
Metal nanoparticles have been extensively used in the synthesis of organic
molecules during the last few decades especially due to their high catalytic activity. Organic reactions
involving C-H functionalisations are very much in demand as they provide a direct method of
derivatisation of organic molecules, thus making the process economical. In the recent years, metal
nanoparticles catalysed C-H activation reactions have led to the design of useful molecules especially
heterocyclic motifs which form the core structure of drugs and thus have high biological and industrial
importance.

Methods:
In this review, we present a collection of reactions where metal nanoparticles are instrumental
in the synthesis and functionalization of heterocycles via C-H activation. The review consists
of three units namely, Nano-copper catalysed C-H activation reactions, nano-palladium catalysed CH
activation reactions and other nano-metals catalysed C-H activation reactions.

Results:
The discussion reflects the scope of nano-metals as effective catalysts for the synthesis and
functionalization of heterocycles as well as the efficiency of nano-metals towards catalysing economic
and environmentally viable reaction protocols.

Conclusion:
The theme of this review is to correlate nanometal catalysis, heterocyclic synthesis and
C-H activation, each of which in itself forms an integral part of modern day chemical research. Thus,
the review will hopefully highlight the need for future development and research in this area and be
instrumental in guiding researchers towards fulfilling that goal.

Published: December 2018

Abstract: The objectives of the research are to examine: (1) the relationship between parents’ education level as an indicator of socioeconomic status (SES) with students’ mathematics achievement, and (2) the interaction between parents’ education level and the intensity of parental involvement in predicting students’ mathematics achievement. The sample (N=2,867) was selected through stratified random sampling of Indonesian high school National Examination (NE) test takers in 2016. The sampling was based on careful consideration of the representativeness and the distribution of provinces, gender, type of school (general-vocational), and school status (public-private). Data was analyzed using parallel multiple mediator analyses. The findings highlight that: (1) compared to fathers, mothers’ education level had a stronger contribution to students’ achievement in mathematics, and (2) mothers’ involvement mediated the relationship between mothers’ level of education and students’ mathematics achievement. However, more intensive parental involvement was associated with lower mathematics achievement. Keywords: SES, mathematics, parents’ education levels, involvement STATUS SOSIAL EKONOMI, KETERLIBATAN ORANGTUA DALAM BELAJAR DAN HASIL BELAJAR MATEMATIKA SISWA SMA DI INDONESIA Abstrak: Penelitian ini bertujuan untuk menguji: (1) kaitan antara tingkat pendidikan orangtua sebagai indikator status sosial ekonomi (SSE) dengan hasil belajar matematika siswa, dan (2) interaksi antara tingkat pendidikan orangtua dengan intensitas keterlibatan orangtua dalam memprediksi hasil belajar matematika anak-anaknya.

Published: December 2018

Актуальність. Основними етіологічними факторами гострого простого бронхіту у дітей є респіраторнотропні віруси, у зв’язку з чим препарати інтерферону можуть бути використані при лікуванні відповідних респіраторних захворювань. Мета: вивчення клініко-імунологічної ефективності рекомбінантного інтерферону альфа-2b при лікуванні гострого простого бронхіту в дітей. Матеріали та методи. Під наглядом перебувало 49 дітей віком від двох до шести років, хворих на гострий простий бронхіт, 23 дитини отримували препарат Лаферобіон®, що містить рекомбінантний інтерферон ­альфа-2b. При проведенні роботи використовувалися клінічні й лабораторні методи дослідження. Тяжкість стану хворого оцінювалася за Bronchitis severity score (шкалою BSS). Лабораторне дослідження включало загальний аналіз крові, сечі, застосовувались імуноферментні методи. Етіологічний діагноз встановлювався на підставі вірусологічних методів дослідження. При визначенні концентрації інтерферону гамма використовувався набір «Гамма-інтерферон-ІФА-БЕСТ А-8752» фірми «Вектор Бест»; лактоферину — набір Нuman Lactoferrin NK 329 Edition 06-16 виробництва компанії Hycult Biotech (USA), нейтрофільних a-дефензинів 1–3 — реактиви Нuman HNP NK317 Edition 08-16 виробництва компанії Hycult Biotech (USA). Результати. У всіх дітей, хворих на гострий простий бронхіт, захворювання почалося гостро й проявлялося катаральним і загальнозапальним синдромами. Згідно з оцінкою ознак гострого простого бронхіту за шкалою BSS на початку захворювання і в періоді реконвалесценції, застосування в терапії рекомбінантного інтерферону альфа-2b сприяє більш швидкому зменшенню всіх клінічних проявів захворювання й збільшенню вмісту лактоферину в ротоглотковій рідині до періоду реконвалесценції.
