Abstract  - The development of technology that getting increasingly has an impact on a mobile device. In this era, mobile phone is a communication tool that is flexible, easy to carry anywhere, and its function is almost the same as the computer. The operating system that mobile phone has got increasingly. One of them is that Android operating system has grown rapidly and almost dominates the mobile market. The development of technology and the increase of necessities life make people have to work harder to sufficient their life. People compete to sufficient the needs and keep up the development that exists, but not everyone is able to sufficient it. It makes people want to do crimes like theft, corruption, murder, etc. This happens because someone is too obsessed with their desire. so they are afraid and anxious if they cannot sufficient and achieve their desire. Anxiety can be interpreted as an uncertain fear with a feeling of uncertainty and helplessness that can cause an uncomfortable feeling. So, it triggers their self to do bad things. In this phenomenon is needed an application that can be used to determine the level of anxiety because knowing the level of anxiety early can prevent people to do bad things. The measurement applications of anxiety levels with HARS scale are made based on the Hamilton Anxiety Rating Scale (HARS).
Evaluasi Keakuratan Model Beneish M-Score Sebagai Alat Deteksi Kecurangan Laporan Keuangan (Kasus Perusahaan Pada Otoritas Jasa Keuangan di Indonesia)
Authors: Santosa Setyarini , Ginting Josep
Published: September 2019

This research has been conducted aiming to see in more detail whether the fraud detection model that has been used so far, the Beneish M-Score, is capable of being one of the tools to see financial report fraud occurring in the business world. This is interesting to study considering that many companies in the Financial Services Authority (OJK) in Indonesia receive warnings and even fines for the delay in submitting financial reports to Capital Market Authority.To carry out the analysis process as in the objectives in the first paragraph, the research team took a sample of 23 companies on the Indonesia Stock Exchange, where the companies were in the list of OJK. The 23 companies that were sanctioned by the OJK compared to 23 not sanctioned companies. In sample of companies that were sanctioned by the OJK, the number of non-manipulator companies according to the Beneish M-Score calculation was 62% and for companies included in the manipulator classification only 38%. Whereas in the sample of companies not subject to sanctions from the OJK, the number of companies included in the non-manipulator category is actually smaller, 52%, calculated using M-Score. This is the main basis for further research.In this study, the analysis process is carried out by quantitative explanatory analysis using probit regression models (probit models), on financial statement data which are categorized into two, the financial ratio with original data from OJK (audited) and the financial ratio with data modification (advanced business analysis). The results show that Beneish M-Score Model could not be implemented effectively to detect the fraud in the companies under control by OJK because only 2 (two) variables influence the existence of fraudulent, are Asset Quality Index (AQI) and Total Accrual To Total Assets (TATA). Thus, it is appropriate and important for the Beneish M-Score modeling to be equipped with other models that are more able to explain.

The banking crisis reflects the liquidity crisis and bankruptcy of banks in the financial system. The financial crisis that occurred in mid-1997 resulted in a financial crisis that had a severe impact on the Indonesian economy. This made it aware of the importance of building a financial crisis early detection system to prepare for a crisis. The crisis occurs due to several macroeconomic indicators undergoing structural changes (regimes) and contain very high fluctuations. Combined volatility models and Markov regime switching are very suitable for explaining crises. The M2/international reserves indicator from 1990 to 2018 was used to build a crisis model. The results showed that the Markov regime switching autoregressive conditional heteroscedasticity model MRS-ARCH(2,1) could explain the crisis that occurred in mid-1997. Based on this model, in the future the crisis might occur if the M2/international reserves indicator decreased minimum of 13%

Authors: Kumar M. Avinash , Srinivasan M. , Ramasamy P.
Published: September 2019

Global heat transfer computations were performed for the investigation of thermal stress in a Czochralski silicon crystal. The temperature distribution, thermal stress properties including maximum shear stress and von Mises stress distributions at two different axial crystal positions have been investigated with the help of heat transfer simulations. By analyzing the obtained results, the thermal stress maxima during the Czochralski growth process can be controlled by applying optimal crystal rotation of 8 rpm and counter crucible rotations of 5 and 15 rpm for a crystal position of 100 mm and 300 mm. This shows that by applying optimal crystal and counter crucible rotations throughout the growth process, the thermal stress maxima of a growing crystal can be reduced.

Published: September 2019

Non-destructive tests use techniques which allow a body to be evaluated without changing its physical, mechanical and dimensional features and without compromising its future use. Impulse tomography analysis is a non-destructive method which allows a piece of wood to be analyzed by passing mechanical waves through it, allowing researchers to evaluate its qualities in advance and detect the presence of defects. This research reports the assessment of the efficiency of impulse tomography as a technique for identifying defects and the in situ evaluation of tree wood from Amazonian timber species. The data were collected at INPA's Tropical Forestry Experimental Station (ZF-2), located at BR 174, Manaus/AM, in a plot 1 (one) hectare in size, where 7 species were chosen at random. For evaluation, the ARBOTOM pulse tomograph at DAP (diameter at breast height) was used to rapidly capture cross sectional images of the wood. Next, the trees were cut to evaluate cross sections of the wood by eye and samples were taken to determine the density of the wood. The results enabled researchers to detect the presence of distinct zones in the wood by varying the mechanical wave speed indicated by various colour zones revealed in the X-ray. These colour differences are attributable to variations in density related to the different wood substances in the tree. It was found that the wood density and mechanical wave velocity correlated with R² 0.647. The dynamic elastic modulus of the species studied was satisfactory, showing a good degree of resistance. Impulse tomography technique provides complete information and can assist forest managers to make a decision about tree felling that is guided by the assessment of the internal quality of the wood.

Published: September 2019

In this work a thermodynamic analysis for a condensation-extraction steam turbine capable of driving a 40 MVA electric generator in a sugar-alcohol factory was carried out. Sensibility analyses were performed to evaluate the behavior of the overall energy efficiency of a plant with the condensation-extraction steam turbine in function of the boiler efficiency, the specific consumption of steam in the processes as well as the condensation rate in the turbine. The analysis results have shown that this turbine in the cogeneration system contribute to increasing the power generation, although the condensation reduces the overall efficiency of the plant. It has also been observed that the plant efficiency is very sensitive to the condensation rate variation and increases with the demand for steam in the processes.

Authors: Golubina E. N. , Kizim N. F. , Chekmarev A. M.
Published: September 2019

The effect of local vibration at interfacial layer of a heterogeneous liquid system on the wettability of the material of interfacial formations based on the salt of the d- or f-element of di-(2-ethylhexyl)phosphoric acid adhered to glass has been investigated. It is shown that in the field of mechanical vibrations one can obtain a material with a given value of the wetting angle, which has hydrophobic properties. It is established that the influence of mechanical vibrations is due to changes in the hydrodynamic situation in the transition region and is the result of complex interactions mainly hydrodynamic and coagulation processes in the interfacial layer of the di-(2-ethylhexyl)phosphoric acid - solvent system / water solution of the d- or f-element salt. The dependence of the wettability of the material of interfacial formations adhered to glass on the parameters of the force field (vibration frequency, amplitude), the design features of the experimental setup, and the composition of the system is shown.

Authors: Khanchuk A. I. , Ivanov V. V. , Ignatiev E. K. , Kovalenko S. V. , Semenova D. V.
Published: September 2019

Late Albian-early Cenomanin epoch of Au-Cu porphyry mineralization has been distinguished within the Sikhote-Alin. It is associated with the Alb-Cenomanian granitic rocks which emplacement coincided with the processes of orogeny and neoformation of continental lithosphere caused by compressive stress in the setting of transform continental margins of that time. The intrusion of the granitic magma into the crust of Jurassic accretionary wedge terranes and Early Cretaceous terrane of epicontinental turbidite basin provoked development of Au-Mo-Cu and Cu-Au-W ore genesis, respectively. U-Pb dating of zircons from host granites of the Malmuzh Au-Cu deposit yielded Alb-Cenomania age of 100-95 Ma. This age harmonizes with the age data reported by other researchers on the granitic rocks of East and Southeast Asia which are productive for hydrothermal mineral deposits of copper, gold, tin and other metals. Such age consistency suggests that there is Albian-Cenomanian metallogenic megabelt extending throughout the entire East Asian continental margin.

The vertical isotopic profile of the pingo Messoyakha-1 (coordinates: 68°30′32″ N, 79°59′53″ E) ice core, obtained in the south of the Gydan Peninsula in the Middle Messoyakha swell. There is no significant variations of the isotopic composition of pingo ice core: δ18О values vary from -14.98 to -16.60‰, δ2Н values vary from -117.9 to -12.8. This small scatter of values is probably the result of intense heaving and rather rapid formation of the pingo. Basing on the features of the pingo, it can be assumed that initially there was a lake of 0.5 km length and 0.3 km width in this site. Then, as a result of water draining to a nearby river, the lake began to dry out and alas, which occupies most of the primary lake area, was formed. Pingo arose during the freezing of the alas under its gradual drying.

Authors: Salyaev R. K. , Rekoslavskaya N. I. , Stolbikov A. S.
Published: September 2019

Very high contents of the interferon, CD4 and CD8 T lymphocytes were found in blood and spleen cells after the oral vaccination of mice with the “early” protein of high-risk oncogenic papillomavirus HPV16 E2 by using immunoassays analyses: ELISPOT for the detection of the content of interferon, Western-blot hybridization and enzyme immunoassays for analyses of СD4 and CD8 T lymphocytes. Both blood cells and splenocytes showed high content of alive mononuclear cells during ELISA and ELISPOT analyses that had very characteristic features for T lymphocytes. The ratio of CD4/CD8 was very close to 1 after the quanttitive determination by the enzyme immunoassays with appropriate antibodies. It was concluded that the “early” protein HPV16 E2 participated in the activation of the immune system during pathogenesis and neoplasia.

Published: September 2019

Sclerotinia diseases and Phomopsis stem canker, among the most serious diseases threatening the success of sunflower (Helianthus annuus L.) production across the world, have been of increasing concern in recent history, and there is a need for additional inbred lines with resistance to these diseases. While breeding new lines capable of thriving in agricultural landscapes riddled with these widespread diseases, it is essential that lines also exhibit other desirable traits such as high yield potential, satisfactory fatty acid composition (e.g., high oleic acid), and herbicide tolerance (e.g., to imidazolinones), along with overall agronomic performance suitable to the northern Great Plains climate in the United States, and similar climates across other continents. A maintainer inbred germplasm line, HA 482 (Reg. no. GP‐364, PI 690015), and two restorer inbred germplasms, RHA 483 (Reg. no. GP‐365, PI 690016) and RHA 484 (Reg. no. GP‐366, PI 690017), have been developed with the pedigree breeding method, evaluated through the use of testcross hybrid trials for both disease resistance and agronomic traits, and released by the USDA–ARS, Fargo, ND. All three lines have high oleic acid composition in the seed oil and exhibit resistance to Sclerotinia and Phomopsis stem canker, and both RHA 483 and RHA 484 are imidazolinone tolerant.

This study aims to increase students' interest and mathematics learning achievements on the subject of rank numbers, root shapes and logarithms. In this study I used a concept map. Concept maps are a tool in the form of a scheme that states the relationship between concepts starting from the general to the specific ones which are connected through arrows in the form of propositions. Proposition is two or more statements about a concept that are related to words or arrows. Concept maps play an important role in meaningful learning, with concept maps of students being trained to think, in students being asked to think about concepts or events they already know. Meaningful learning is easier to take place if new concepts are linked to concepts that are inclusive, inclusive concepts that are basic concepts that are more general in nature. Concept maps must be arranged in a hierarchical manner, which means that a more inclusive concept is at the top of the map, the concepts below are sorted into less inclusive ones.

The monitoring and managing of such water dispensers is currently performed with much human interference. Moreover, individuals living in a fast moving world are negligent and are not motivated to drink the required level of water recommended by medical practitioners. In order to find solutions for the above problems, a Potable Water Monitoring and Management System was developed. This system uses an Arduino Mega 2560 micro controller together with 2 load cell sensors as the major components to extract the necessary information regarding water level of water cans and employee water bottles. Barcode reader was used to extract employee details from the barcodes embedded in the employee water bottles. According to the facts collected through the literature review, it was found that there were no current systems that detect the water level of water dispensers using load cells. Moreover, there were no efficient methods to track the daily water intake of employees in an organization as well. The purpose of this Potable Water Monitoring and Management System is to provide an easy and efficient methodology to maintain the water dispensers using minimum human interference and to regulate and notify employees about their daily water intake levels. This system also enables the storage and management of details of employees and water can suppliers.
A Reservoir Information Extraction Method Based on Improved Hilbert-Huang Transform
Authors: Yang Qingmi
Published: September 2019

Hilbert-Huang transform (HHT) is a nonlinear non-stationary signal processing technique, which is more effective than traditional time-frequency analysis methods in complex seismic signal processing. However, this method has problems such as modal aliasing and end effect. The problem causes the accuracy of signal processing to drop. Therefore, this paper introduces the method of combining the Ensemble Empirical Mode Decomposition (EEMD) and the Normalized Hilbert transform (NHT) to extract the instantaneous properties. The specific process is as follows: First, the EEMD method is used to decompose the seismic signal to a series of Intrinsic Mode Functions (IMF), and then The IMFs is screened by using the relevant properties, and finally the NHT is performed on the IMF to obtain the instantaneous properties.

BUDE SQUEEZE-OUT NA KAPITÁLOVOM TRHU EFEKTÍVNEJŠÍ? (POOHLIADNUTIE SA ZA OSTATNOU REGULÁCIOU PRÁVA VÝKUPU)
Authors: Čunderlík Ľubomír
Published: September 2019

Právo výkupu (squeeze-out) je právnym inštitútom sledujúcim ekonomické záujmy akcionárov. Svojou právnou povahou je jeho regulácia predmetom viacerých právnych odvetví: práva kapitálového trhu s ohľadom na predmet práva výkupu, ktorým sú investičné tituly obchodované na transparentných kapitálových trhoch pod verejným dohľadom, práva obchodných spoločností (akciového práva s dôrazom na ochranu menšinových akcionárov) a koncernového práva. V článku sa autor zameriava na vybrané problémy práva výkupu. Opiera sa o viaceré akademické názory, pričom neopomína reflektovať realitu kapitálového trhu. Článok sa zaoberá zdôvodnením existencie tohto inštitútu a identifikáciou jeho nedostatkov v národnej právnej úprave (v zákone o cenných papieroch a investičných službách).

By the contract for work, the contractor undertakes to perform certain work and the employer undertakes to pay the price for its performance. Work as defined by the law manufactures specified products (provided the manufacture does not fall under the notion of a purchase contract), the maintenance, repair or modification of certain items or the result of other activities. Fabrication, repair or modification of buildings or parts thereof shall be always covered by contracts for work.
