Abstract
Technology is growing very fast. We can now access everything using internet anywhere and anytime. That is why it is important to have internet security since we are always open to an online fraud, property damage and theft. IDS (Intrusion Detection System) can be used to detect any system or network attack. In this empirical study, we use dataset from KDD Cup 1999, which consist of five classes: normal, probe, dos, u2r and r2l. There is some classifier method for IDS, but in this study, we will use Fuzzy Robust Kernel C-Means (FRKCM) with Polynomial kernel and Fuzzy Entropy Kernel C-Means (FEKCM) with RBF kernel to find a better result that increase accuracy of the network attacks. There will be an accuracy comparison between FRKCM method and FEKCM method. The accuracy result from this study is 99% with time execution faster.

Abstract
Starting from the analogy of gravitational forces to explain the volume of bilateral trade, the Gravity model has become a very popular model in international trade research. The Gravity Model has also been widely developed by adding various independent variables. Instead to measuring trading volume and various factors that influence the volume of trade, there is not much utilization of the gravity model to measure trade potential. This research is intended to implement a gravity model to measure the potential of Indonesian fruit trade. The measurement of trade potential is carried out by using data on the three main group of Indonesian exported fruits (based on 6 digits HS Code) which traded in 16 years. The classical gravity model, employed in this research contains independent variables, such as the amount of tariffs, the existence of free trade agreements, population, GNP of each country, distance and share of trade. The method of analysis used refers to the gravity model applied by Susanto, et al (2007) and regression analysis method applied by Arita et al (2014). Since its easily fits with some important stylized facts, it is easy to use real data, and also easily estimates using Ordinary Least Square (OLS), the Gravity Model can be a comprehensive instrument for managing big data to present rapid and dynamic estimates of international trade in line with the demands of the Revolution Industry 4.0.

Abstract
The second order indicator model can be the first order having formative or reflective indicators of an underlying second order. The research used principal component analysis in the first order and factor analysis in the second order. The variable used in the research was ihsan behavior. This research aims to apply multivariate analysis, i.e. the principal component analysis in the first order and the factor analysis in the second order to obtain the latent variable data of ihsan behavior in the second order indicator model. The data used in this research were primary data by distributing questionnaires. Respondents of this research were lecturers of the Faculty of Economics and Business at the University of X. The research results generated latent variable data in the form of ihsan behavior. Ihsan behavior was reflected in six indicators, i.e. doing something perfectly, repaying goodness with more goodness, reducing optimally unpleasant consequences, as a solution when justice cannot be realized, as a logical consequence rather than faith, and as an investment in future success.

Published: June 2019

Abstract
In crystal engineering, the presence of different types of anion may alter the structure of transition metal complexes. Thus, the anions may also govern the properties of the metal complexes. Hereby we reported a structural analysis of polymeric copper(II)-pyrazinamide (pza) complexes prepared from copper(II) sulphate and copper(II) chloride. The complexes were crystallised using a bench-top technique with copper(II):pza molar ratio of 1:2 in a layered H2O-CH3OH solvent at room temperature. Single crystal XRD, ATR-IR and melting point apparatus were used to analyse the structure and characterise the complexes. Single crystal XRD analyses reveals that both complexes, [Cu( µ-pza)(SO4)(H2O)2]n (A) and [Cu(pza)2( µ-Cl)2]n (B) forms a 1D polymeric structure with different metal-ligand connectivity around the octahedral copper centre. The copper centres are also linked by different ligand, namely pyrazinamide in A and chloride in B. Thus, the Cu…Cu distances in both complexes are different, 6.719 Å in A and 3.658 Å in B. Unlike in A, the crystal structure of B has two unique copper centres. In addition, crystal structures of A and B were also compared to closely related copper(II)-pza complexes from published literature. As also observed in many metal complexes, crystal structures of copper(II)-pza complex were affected by the anion of the metal salts used in the reaction, in which the anion also involves in the crystal structures.

A Study of Kir6.2 Gene Sequence in Rat Model of Type 2 Diabetes Mellitus Treated by CSN1S2 Protein of Etawah Crossbred Goat Milk
Authors: Meidinna Hazna Noor , Fatchiyah Fatchiyah 
Published: June 2019

Abstract
Type 2 diabetes mellitus (T2DM) is a metabolic disease characterized by hyperglycemia. High blood glucose levels in T2DM patients are treated by sulfonylurea. However, the long-term use of sulfonylurea can affect the regulation of glucose homeostasis and cause hypoglycemia. The cascade gene associated with the hypoglycemia is Kir6.2, a constituent of ATP-sensitive potassium channel (KATP), in the neuron. Kir6.2 mutations cause dysregulation of insulin secretion by pancreatic beta cells and glucagon secretion by pancreatic alpha cells. The aim of this study was to analyze the effect of CSN1S2 protein of etawah crossbred goat milk on Kir6.2 gene sequences in the rat model of T2DM. The experimental animals used were male Wistar rats (Rattus norvegicus) which were divided into two major groups, namely control group and T2DM group. Each group was administrated by CSN1S2 protein with the dose of 375 mg/kg BW, 750 mg/kg BW, 1500 mg/kg BW, and without CSN1S2 protein administration. Each group was replicated three times. DNA was isolated from the rat brain. Kir6.2 gene was amplified by using specific primers. PCR products were purified and sequenced by using ABI 3730xl DNA Sequencer. DNA sequences were analyzed by using MEGA7 software. Amplification of the Kir6.2 gene produced 1173 bp DNA. There was no change in the Kir6.2 sequence in all treatments. The 25 mg/kg BW dose of streptozotocin had no effect on Kir6.2 gene sequence in the rat brain. This study also showed that administration of CSN1S2 protein at the dose of 375 mg/kg BB, 750 mg/kg BW, and 1500 mg/kg BW did not cause mutations in the Kir6.2 gene in the brain of the rat model of T2DM.

Abstract
Growth Differentiation Factor-9 (GDF-9) and Bone Morphogenetic Protein Receptor 1a (BMPR-1a) was a member of the transforming growth factor-β (TGF-β) superfamily known to regulated ovarian functions in mammals. In addition, Luteinizing Hormone (LH) also has an important role in ovarian function. The objectives of this research are to observe effect of LH on the GDF-9 and BMPR-1a expression in granulosa cells (GCs) culture. Bovine ovaries were obtained from a slaughterhouse and carried to the laboratory within 30 min in a container kept at 37 °C in saline containing gentamicin and amphotericin. The ovaries were washed with pre-warmed PBS supplemented with gentamicin and amphotericin. Granulosa cells were collected from follicles by aspiration using a syringe with needle (20G). The cells were centrifuged for 1 min at 800g at room temperature and washed twice in DMEM/F12 medium and filtered through a stainless steel filter (100 um) to get the GCs then seeded in 6 well culture plates. The cells were cultured at 37 °C in a 5% CO2 atmosphere for 24 h and then the wells were washed with PBS to remove unattached cells. The culture medium was replaced with serum-free medium supplemented with LH at 100 ng/mL and cultured for 24 h. Total RNA was extracted from GCs using TRIsure. The RNA quality and quantity were estimated by using spectrophotometer at 260/280 nm. Aliquots (1 ug) of total RNA from each pool of GCs were independently reverse-transcribed to cDNA. The mRNA expression of GDF-9 and BMPR-1a was estimated by the quantitative real-time PCR method. The results showed that LH added to the culture medium can increase the expression of GDF9 and BMPR-1a of granulosa cells.

Published: June 2019

Abstract
The ‘X’ field is an oil-producing field in the Central Sumatra Basin. Central Sumatra Basin is the largest oil-producing sedimentary basin in Indonesia. The field is an area in the form of onlaping Bekasap Formation to the Basement High. The onlapping feature has potential for stratigraphic traps. This study aims to identify the potential stratigraphic traps for hydrocarbon accumulation, the distribution of sandstone reservoirs, facies types and the depositional environments. The data used in the study are 3D seismic data, well log, and core data. The research methods used including the analysis of electrofacies based on well log, seismic attributes, and conceptual geology model. The research shows that there is a stratigraphic trap in the form of intra-formation and regional traps. Intra-formation traps were formed vertically by the intersection of sandstone and shale lithologies and lateral facies changes, whereas the regional traps are formed by the shale layer of Telisa Formation and Bekasap Formation with onlapping on the Basement High. Based on AI inversion and RMS amplitude show the distribution of Top A sandstone reservoir is Northeast - Southwest on onlaping zone to the Basement High. The reservoir was deposited in depositional environment as wave dominated delta which is four facies associations: distributary channel, upper shoreface, lower shoreface, and offshore facies.

24-Hour vs. Spot Urinary Sodium and Potassium Measurements in Adult Hypertensive Patients: A Cohort Validation Study
Authors: Wan Elizabeth R , Cross Jennifer , Sofat Reecha , Walsh Stephen B 
Published: June 2019

Abstract

BACKGROUND
Sodium intake is correlated with the development of hypertension. Guyton’s principals suggest that the 24-hour urinary sodium excretion reflects sodium ingestion over the same period. 24-hour urine collections are arduous to collect, so many centers use spot urinary measurements instead. We compared spot to matched 24-hour urinary electrolyte measurements.

METHODS
We examined 419 hypertensive patients from the UCL Complex Hypertension Clinic. 77 had matched and complete 24-hour and spot urinary and serum biochemistry to examine.
We compared the spot and 24-hour urinary; sodium concentration, Na/Cr ratio, FENa, Kawasaki and Tanaka estimated sodium excretion as well as the potassium concentration, K/Cr ratio, Kawasaki and Tanaka potassium excretion.

RESULTS
Our cohort was 58% male and the median age was 41 years. The 24-hour and spot Na concentrations correlated moderately (r = 0.4633, P &lt; 0.0001). The 24-hour and spot Na/creatinine ratios correlated weakly (r = 0.2625, P = 0.0194). The 24-hour and spot FENa results showed a weak negative correlation (r = −0.222, P = ns). The 24-hour sodium excretion and the Kawasaki-derived spot urine sodium excretion correlated moderately (r = 0.3118, P = 0.0052). All Bland–Altman analyses showed poor agreement.
The 24-hour and spot potassium concentrations correlated very poorly (r = 0.1158, P = ns). The 24-hour and spot urinary K/creatinine ratios correlated weakly (r = 0.47, P ≤ 0.0001). 24-hour and Kawasaki and Tanaka estimated potassium excretions correlated much better (r = 0.58, P &lt; 0.0001).

CONCLUSIONS
Spot urinary measurements of sodium give a very poor understanding of the natriuresis occurring over the same 24-hour period. The Kawasaki and Tanaka estimations of the 24-hour sodium excretion showed a much lower correlation than previously reported.
Bacillus pumilus increases boron uptake and inhibits rapeseed growth under boron supply irrespective of phosphorus fertilization
Authors: Masood Sajid , Zhao Xue Qiang , Shen Ren Fang 
Published: June 2019

AbstractThe present study was carried out to investigate how plant growth-promoting bacteria (PGPB) influence plant growth and uptake of boron (B) and phosphorus (P) in rapeseed (Brassica napus). Rapeseed was subjected to control, B, P and B + P treatments, either with or without B. pumilus (PGPB) inoculation, and grown in pot culture for 6 weeks. In the absence of B. pumilus, the addition of B, P or both elements improved the growth of rapeseed compared with the control. Interestingly, B. pumilus inoculation inhibited plant growth and enhanced B uptake under B and B + P but not under control and P conditions. In addition, B. pumilus inoculation decreased the pH of soil under B and B + P supplies. Bacillus pumilus inoculation thus increased rapeseed B uptake and inhibited growth under B supply, which suggests that the effects of PGPB on rapeseed growth depend on the addition of B to soil. Bacillus pumilus inoculation may therefore be recommended for the enhancement of rapeseed B levels in B-deficient soils but not in B-sufficient ones.
The Screening Utility and Ecological Validity of the Neuropsychological Assessment Battery Bill Payment Subtest in Older Adults with and without Dementia
Authors: Kenney Lauren E , Margolis Seth A , Davis Jennifer D , Tremont Geoffrey 
Published: June 2019

Abstract

Objective
The Neuropsychological Assessment Battery Bill Payment subtest has shown strong diagnostic accuracy in dementia due to Alzheimer’s disease (AD) versus non-AD. Its relationship to mild cognitive impairment (MCI) or all-cause dementia has not been fully examined nor has its ecological validity as a proxy of financial independence.

Method
We describe 270 women (63%) and men (age = 72 ± 8.39) who completed Bill Payment during outpatient neuropsychological evaluation. Seventy-one were cognitively normal (CN), 160 had MCI, and 39 had Dementia. Two hundred fourteen were independent in money management, 31 were assisted (had oversight/some help), and 25 were dependent (relied on others). Receiver operating characteristic (ROC) curves tested Bill Payment’s utility as a dementia screen. Kruskal–Wallis tests examined whether Bill Payment differed by levels of financial independence.

Results
At a cutoff of 17, Bill Payment had strong sensitivity (0.87) and specificity (0.80) for dementia versus CN cases. A cutoff of 15 distinguished dementia from MCI (Sn = 0.64, Sp = 0.85), whereas a cutoff of 16 distinguished dementia from functionally unimpaired cases (MCI + CN) with greater sensitivity and similar specificity (Sn = 0.74, Sp = 0.81). Sensitivity attenuated in MCI versus CN cases (Sn = 0.46, Sp = 0.83). Those who were independent in money management had higher scores than assisted and dependent cases (p ≤ 0.046). Assisted and dependent cases were no different (p &gt; 0.05).

Conclusions
Bill Payment is a valid screen of all-cause dementia. Lower Bill Payment scores may mark subtle functional decline beyond cognitive impairment alone. Specifically, results provide preliminary evidence of Bill Payment’s ecological validity as a measure related to financial independence. It may prove useful when impaired financial abilities are suspected but unreported.

Published: June 2019

Abstract
Two simple validated and highly selective methods for analysis of paracetamol, codeine, guaifenesin and pseudoephedrine or phenylephrine quaternary mixtures were developed. The first method is a high performance liquid chromatography with diode array detection method where separation was successful using Agilent C18 (150 × 4.6 mm) column, gradient elution of phosphate buffer pH 3, methanol and acetonitrile and diode-array detection at 210 nm. The second method is a HPTLC method followed by densitometric measurement of the spots at 257 nm. Separation was carried out on Merck HPTLC aluminum sheets of silica gel using methylene chloride: methanol: glacial acetic acid: ammonia (17.8: 1.68: 0.4: 0.12, v/v) mobile phase. The methods were applied successfully for analysis of both quaternary mixtures in laboratory-prepared tablets and also validated in regards to linearity, precision, accuracy, sensitivity and stability.
Occupational structure in Ireland in the nineteenth century: data sources and avenues of exploration
Authors: Begley Jason , Geary Frank , Stark Tom 
Published: June 2019

Abstract
This paper considers structural change in post-Famine Ireland through an examination of changes in the allocation of the labour force across three broad production sectors: primary, secondary and tertiary. To do so, it makes extensive use of the Irish Census of Population from 1821 to 1911 as a source of occupational information. While there are a number of concerns with these returns, outlined and explored here, the Irish census remains the most complete source of information available on male and female labour force activity and occupations in Ireland during this period. The outcome of this exercise is a picture of Irish primary, secondary and tertiary sector employment during the latter half of the nineteenth century that is consistent with that of an economy undergoing a development transition: modernising albeit slowly. While Ireland was the poorest region of the UK economy, it was one of the richer European economies in terms of GDP per head and undergoing a development transition similar to a number of European economies during this period.
