Authors: Sorongan Erick , Hilmansyah Hilmansyah , Hadiyanto Hadiyanto
Published: October 2019

The application of information systems with various types of convenience offered can reflect the quality of service of an organization, the quality of service can be said to be very good if the service meets the needs and expectations of users. This kind of evaluation can be done by applying a tested model but problems arise when latent variables in the method used are not fully able to identify factors that influence user satisfaction. From the results of research using the end user satisfaction model, the R-Square value is 0.653, which means that 65.3% of user satisfaction can be found through latent variables found in the EUCS model while the remaining 34.7% can be explained through external variables. This study aims to analyze external factors outside the EUCS model, one of which is by using the information system quality variables contained in the Delone and Mclane information system success model. The way to do this is to add an external variable to the EUCS model and then analyze the outer model and analyze the structural model using the structural equation model. The results showed that the independent system quality variable has a t-statistic value of 3.445 or greater than t-table 1.96 which means that the external latent variables of the Delone and Mclean model can be used to explain the satisfaction factors (from the external variable side) of the user information system on the EUCS model.

Guitar is a popular musical instrument in the world and is a metronome for every use in various music events and its correlation. As a metronome, the guitar must be well standardized on the quality of each part so that sound that comes in line with the user's expectations in this case is the guitarist. Damage to the guitar is something normal because of its intense use so it needs proper handling in the repair process. The easiest thing is to bring a broken guitar to the experts, but when there are not many guitar service experts or a long enough distance to reach it, then guitar repairs need to be done immediately. Therefore, it is necessary to develop a system that can act as a tutor in the maintenance and repair of guitars by utilizing artificial intelligence embedded in the system. With the help of artificial intelligence, it is expected that the system can assist in the decision making of guitar technicians in the process of making guitar repair decisions based on the symptoms that occur. Decision making used uses the certainty factor method based on certainty factors. After going through the equivalence partitioning testing process, in general this system produces a total percentage of 100% on the success of the item test by experts in the testing process of the 25 items tested. Thus the application meets the requirements for making the program, which is readable and valid.

Big companies that have many branches in different locations often have difficulty with analyzing transaction processes from each branch. The problem experienced by the company management is the rapid delivery of massive data provided by the branch to the head office so that the analysis process of the company's performance becomes slow and inaccurate. The results of this process used as a consideration in decision making which produce the right information if the data is complete and relevant. The right method of massive data collection is using the data warehouse approach. Data warehouse is a relational database designed to optimize queries in Online Analytical Processing (OLAP) from the transaction process of various data sources that can record any changes in data that occur so that the data becomes more structured. In applying the data collection, data warehouse has extracted, transform, and load (ETL) steps to read data from the Online Transaction Processing (OLTP) system, change the form of data through uniform data structures, and save to the final location in the data warehouse. This study provides an overview of the solution for implementing ETL that can work automatically or manually according to needs using the Python programming language so that it can facilitate the ETL process and can adjust to the conditions of the database in the company system.

Published: October 2019

One of the services in the university library is an information system to find the availability of library collections and the location of each collection shelf. But not many of these systems provide a mechanism that can recommend visitors not only about the books they want, but also other related books that may be needed. This study uses association rule mining techniques that are applied to library transaction data to identify relationships between books (titles) that attract visitors' attention. Relationships are built on interesting measurements between the titles, namely support and confidence, where support determines the combination of the most frequently borrowed book titles, while confidence produces the possibility that the title of the book will be borrowed along with other books. The pattern of book titles association with high confidence indicates that the titles are very related so it is recommended for visitors to consider borrowing along with the book they are looking for. In addition, the system can also recommend the procurement of new books and rack configurations to improve the visitor's experience when searching for books on the site. In the experiment, the precision of recommendations generated from the system reached 70%. Web applications were developed to help understand the effectiveness of the recommendation system based on association rules.
On approximations of the function |x|s by the Vallee Poussin means of the Fourier series by the system of the Chebyshev – Markov rational fractions
Authors: Patseika P. G. , Rovba Y. A.
Published: October 2019

The approximative properties of the Valle Poussin means of the Fourier series by the system of the Chebyshev – Markov rational fractions in the approximation of the function |x|s, 0 < s < 2 are investigated. The introduction presents the main results of the previously known works on the Vallee Poussin means in the polynomial and rational cases, as well as on the known literature data on the approximations of functions with power singularity. The Valle Poussin means on the interval [–1,1] as a method of summing the Fourier series by one system of the Chebyshev – Markov rational fractions are introduced. In the main section of the article, a integral representation for the error of approximations by the rational Valle Poussin means of the function |x|s, 0 < s < 2, on the segment [–1,1], an estimate of deviations of the Valle Poussin means from the function |x|s, 0 < s < 2, depending on the position of the point on the segment, a uniform estimate of deviations on the segment [–1,1] and its asymptotic expression are found. The optimal value of the parameter is obtained, at which the deviation error of the Valle Poussin means from the function |x|s, 0 < s <2, on the interval [–1,1] has the highest velocity of zero. As a consequence of the obtained results, the problem of approximation of the function |x|s, s > 0, by the Valle Poussin means of the Fourier series by the system of the Chebyshev first-kind polynomials is studied in detail. The pointwise estimation of approximation and asymptotic estimation are established.

The work is both theoretical and applied. Its results can be used to read special courses at mathematical faculties and to solve specific problems of computational mathematics.

It is shown that when machining products from materials with heterogeneous structure, possibilities of management of a condition of a blanket are significantly limited. As an example of management, cutting processing of products from materials with heterogeneous structure – turning of high-strength ﬂame evaporated coverings is considered. Because for an amorphous component of heterogeneous coverings the lack of deformation hardening is peculiar considerable deformation of the cut-off material is observed at their processing and characteristic shaving is formed. Highintensity thermobaric impact on the processed heterogeneous material leads to partial crystallization in a thin blanket with the high content of an amorphous phase. As a result of researches the criterion which quantitatively estimates the statistics, which complexly characterize uniformity of structure of materials and dispersion of their properties, is offered. The criterion allows defining ability of materials to be exposed to cutting without carrying out long experiments.
Space-time diversity signal processing employed by W-CDMA systems
Authors: Tuzlukov V. P.
Published: October 2019

Transmit diversity under transmission of signals from the base station to mobile station using the code-division multiple-access (CDMA) system allows us obtaining the performance gains close to the mobile station receiver diversity without complexity of the mobile station receiver antenna array. The multipath diversity can be achieved using the pre-RAKE precoding at the transmitter that could be employed and there is no need to install the RAKE receiver at the mobile station. We investigate several transmitter diversity techniques employed by wideband CDMA (W-CDMA) systems. We also study a possibility to combine transmitter diversity and precoding that achieves the gain of maximum ratio combining of all space and frequency diversity branches jointly with long-term prediction algorithm. It was demonstrated that the performance of the space-time pre-RAKE method approaches the performance of the maximum ratio combining for all space and frequency diversity branches. It is shown that all closed loop methods depend on the long range prediction to approximate the ideal performance in the fast fading environment.

Published: October 2019

Introducción. Según la Organización Mundial de la Salud (OMS) la epilepsia constituye uno de los trastornos neurológicos más frecuentes en el mundo. Las crisis epilépticas se consideran una manifestación clínica originada por una descarga excesiva de neuronas a nivel cerebral. Su prevalencia es mayor en Latinoamérica y el Caribe que en países desarrollados; las crisis, en la mayoría de los casos, corresponden a la epilepsia del lóbulo temporal, cuya anormalidad anatómica más habitual es la esclerosis del hipocampo. El objetivo es exponer el protocolo básico de epilepsia de manera estandarizada y su utilidad en el planeamiento quirúrgico, y así, conociendo todas las herramientas estudiadas hasta el momento, se realice un adecuado y oportuno diagnóstico. División de los temas tratados. Se realizó una revisión de tema de la literatura existente en las bases de datos Pubmed, Cochrane y Medline desde 1980 hasta 2018 acerca de la epilepsia del lóbulo temporal. Se expone de manera concisa la anatomía, fisiología, fisiopatología, presentación clínica y diagnóstico imaginológico de la patología. Conclusiones. Esta patología se caracteriza por tener el foco epileptogénico en los lóbulos temporales con alta probabilidad de control con técnicas quirúrgicas cada vez menos agresivas. El diagnóstico es inducido a través de la clínica; sin embargo, las nuevas técnicas de imagen estructurales y funcionales son el método diagnóstico de elección en pacientes con sospecha de esta patología y, de esta manera, lograr la realización de un diagnóstico más certero y oportuno.

Published: October 2019

La cirugía, sin duda alguna, ha jugado un papel fundamental en la evolución de la medicina moderna: por medio de sus avances, la calidad de los tratamientos médicos ha mejorado de manera trascendental la expectativa de vida de muchas patologías.  Algunos autores afirman que sus inicios se remontan a la época de la prehistoria, cuando tribus indígenas ya realizaban procedimientos quirúrgicos como amputaciones, litotomías, ablación de cataratas y trepanaciones de cráneos, entre otros. Sin embargo, su punto de inflexión se marco hace aproximadamente 150 años con el descubrimiento de la anestesia y la posterior aparición del uso de antibióticos.

Published: October 2019

Alum merupakan koagulan yang umum digunakan untuk menurunkan TSS dalam air. Fungsi koagulan adalah untuk mendestabilisasikan partikel koloid sehingga dapat menurunkan kandungan partikel terlarut dan tersuspensi. Koagulan dapat berasal dari bahan alami, seperti kitosan, yang dibuat dari limbah. Limbah kulit udang yang dihasilkan oleh salah satu perusahaan di Kabupaten Kutai Kartanegara mencapai 4,5 ton per bulan. Jumlah yang cukup besar tersebut mendorong pemanfaatan limbah menjadi kitosan sebagai koagulan limbah cair tekstil yang memiliki kandungan TSS melebihi baku mutu, yaitu 518-620 mg/L. Penelitian ini bertujuan untuk mengetahui efektifitas kitosan sebagai koagulan, serta membandingkannya dengan koagulan alum dalam menurunkan TSS. Kitosan dibuat melalui proses preparasi, deproteinasi, demineralisasi, dan deasetilasi. Pengontakkan koagulan dengan limbah cair tekstil menggunakan jartest dengan 100 rpm selama 3 menit dan 40 rpm selama 12 menit. Konsentrasi koagulan kitosan yang digunakan adalah 100, 120, dan 150 mg/L, sedangkan untuk koagulan alum menggunakan dosis optimum. Hasil penelitian menunjukkan bahwa kitosan mampu menurunkan TSS mencapai 89,5% atau 555 mg/L, dengan dosis optimum 150 mg/L. Pada dosis optimum, koagulan tawas mampu menurunkan hingga 91,9% atau 570 mg/L. Efisiensi tawas yang sedikit lebih tinggi dari kitosan menunjukkan bahwa kitosan mampu berperan sebagai koagulan limbah cair tekstil seperti halnya alum.Kata Kunci : kitosan, limbah cair, alum, tekstil, TSS

Psychiatry and Psychotherapy. The Principle of Complementarity.docx
Authors: Chistyakov Maxim
Published: October 2019

 This report considers the differences
between the medical psychiatric and the psychotherapeutic (in particular, the
psychodynamic) approaches to the diagnostics and treatment of mental disorders, and it describes a
generalized model of the psychotherapeutic process. It traces the development
of the relationship between the medical psychiatric and the psychotherapeutic
approaches, which has resulted in different models of the interrelatedness of
these paradigms in different countries (a unified model encompassing both the
psychiatric and the psychotherapeutic approaches, and a model of two relatively
independent approaches). Examples are provided of the difficulties and inconsistencies
which have arisen from attempts to employ different variants of the unified
model that purports to unify the two different approaches into a single whole. It is proposed that
the medical psychiatric and the psychotherapeutic approaches should each be
considered to have their own internal logic, independent from and simultaneously
complementary to that of the other, in accordance with the principle of
complementarity formulated by the physicist Niels Bohr in quantum mechanics for
the systematization of irreconcilable data obtained by observers with differing
perspectives. The author proposes that each patient with a mental disorder
should be examined simultaneously and independently from the point of view of

Negara Kesatuan Republik Indonesia (NKRI) merupakan negara yang berbentuk kepulauan atau nusantara yang terdiri dari beribu-ribu pulau yang sekaligus juga memiliki sifat dan karakter yang berbeda-beda pula.NKRI dikenal juga sebagai negara yang memiliki keragaman budaya, ras, suku, dan agama yang berbeda-beda sehingga tercermin dalam satu ikatan “Bhineka Tunggal Ika” yang artinya “berbeda-beda tetapi tetap satu juga”. Yaitu persatuan bangsa dan negara Indonesia. Perbedaan adalah suatu bawaan kodrat manusia sebagai makhluk Tuhan Yang Maha Esa.

During adolescence the prevalence of certain health risk behaviours, such as binge drinking and illicit substance use, increases. Engagement in these behaviours has been attributed to immature self-regulation, heightened sensation seeking, and peer influence during adolescence. However, more recently, adolescence has been characterised as a time of risk sensitivity rather than universal increases in health-risk behaviour. For example, the extent to which individuals engage in health-risk behaviours may relate to their sensitivity to the social risk involved in engaging in the health-risk behaviour. In the present study we examined how individual differences in social risk perception relate to an individual’s expectation of future involvement in risky behaviour during adolescence. One hundred and twenty-two participants (ages 11-17, mean 14 years) reported their expected involvement in a number of risk behaviours and degree to which they thought a) engaging in these behaviours would make people like them more, and b) not engaging in these behaviours would make people like them less. Social risk perception was operationalised as the perceived social benefit gained from engaging in a risk behaviour, from low (people would like you less), to high (people would like you more). We used linear mixed effects modelling to assess the contribution of social risk perception in predicting individuals expected involvement in health risk behaviours. We found that adolescents who perceived the social benefit associated with engaging in a risk behaviour to be high were more likely to report higher expected involvement in said behaviour. This was true for illicit substance use, aggressive and illegal behaviours, and risky drinking, but not for risky sex. Adolescents who reported a higher degree of peer victimisation showed a stronger relationship between the perceived social benefit of engaging in, and expected involvement in, these risk behaviours. Further, perceived social benefit moderated the relationship between sensation seeking and expected involvement in risky behaviours. Taken together, these data suggest that, across a number of health risking behaviours, adolescents incorporate perceptions of social risk when making decisions regarding their expected involvement. We argue that future investigations of adolescent health risking behaviours should incorporate social risk.
Exogenous testosterone increases status-seeking motivation in men with unstable low social status

Testosterone is associated with status-seeking behaviors such as competition, which may depend on whether one wins or loses status, but also on the stability of one’s status. We examined (1) to what extent testosterone administration affects competition behavior in repeated social contests in men with high or low rank, and (2), whether this relationship is moderated by hierarchy stability, as predicted by the status instability hypothesis. Using a real effort-based design in healthy male participants (N = 173 males), we first found that testosterone (vs. placebo) increased motivation to compete for status, but only in individuals with a low unstable status. A second part of the experiment, tailored to directly compare stable with unstable hierarchies, indicated that exogenous testosterone again increased competitive motivation in individuals with a low unstable status, but decreased competition behavior in men with low stable status. Additionally, exogenous testosterone increased motivation in those with a stable high status. Further analysis suggested that these effects were moderated by individuals’ trait dominance, and genetic differences assessed by the androgen receptor (CAG-repeat) and dopamine transporter (DAT1) polymorphisms. Our study provides evidence that testosterone specifically boosts status-related motivation when there is an opportunity to improve one’s social status. The findings contribute to our understanding of testosterone’s causal role in status-seeking motivation in competition behavior, and indicate that testosterone adaptively increases our drive for high status in a context-dependent manner. We discuss potential neurobiological pathways through which testosterone may attain these effects on behavior.
Theory Integration for Lifestyle Behavior Change in the Digital Age: An Adaptive Decision-making Framework
Authors: Zhang Chao , Lakens Daniel , IJsselsteijn Wijnand
Published: October 2019

Despite the growing popularity of digital health interventions, limitations of traditional behavior change theories and a lack of theory integration hinder theory-driven behavior change applications. In this article we review theories relevant to lifestyle behavior change from a broader psychology literature, and then integrate these theories to a new theoretical framework called adaptive decision-making to address two specific problems. First, our framework represents lifestyle behaviors at two levels, one of individual daily decisions (action-level), and one of larger behavioral episodes (reflection-level), to more closely match the temporal characteristic of lifestyle behaviors and digital data. Second, the framework connects decision-making theories and learning theories to explain how behaviors and cognitive constructs dynamically influence each other, making it a suitable scaffold for building computational models. We map common digital intervention techniques onto the behavioral and cognitive processes in the framework, and discuss possible contributions of the framework to both theory development and digital intervention design.
Predicting Choice Behavior of Group Members
Authors: Spieß Lukas , Bekkering Harold
Published: October 2019

Meaningful social interactions rest upon our ability to accurately infer and predict other people’s preferences. In doing so, we can separate two sources of information: knowledge we have about the particular individual (individual knowledge) and knowledge we have about the social group to which that individual belongs (categorical knowledge). However, it is yet unclear how these two types of knowledge contribute to making predictions about other people’s choice behavior. To fill this gap, we had participants learn probabilistic preferences by predicting object choices of agents that either belonged to a social group (Group condition) or not (Individual condition). We quantified how close predictions for a specific agent are relative to the objective individual preferences of that agent and how close these predictions are relative to the objective group-level preferences to which that agent belongs. As expected, we found that participants’ predictions in the Group condition, relative to the Individual condition, were more similar to the group-level preference, while less similar to the individual-level preferences. We interpret this pattern of results as indicative of a differential weighting of individual and categorical group knowledge when making predictions about individuals that belong to a social group. The results are interpreted in an assimilation account of categorization and stress the importance of group knowledge during daily social interactions.
Agility-based exercise training compared to traditional strength and balance training in older adults: a pilot randomized trial

Background. In addition to generally high levels of physical activity, multi-component exercise training is recommended for the maintenance of health and fitness in older adults, including the prevention of falls and frailty. This training often encompasses serial sequencing of balance, strength, endurance and other types of exercise. Exercise training featuring integrative training of these components (i.e. agility training) has been proposed, as it more likely reflects real life challenges like stop-and-go patterns, cutting manoeuvers, turns and decision-making. In this study, we compared the efficacy of an agility-based training to the traditional strength and balance training approach with regard to selected risk factors for falls and frailty.Methods. We trained twenty-seven community-dwelling healthy seniors (16♂; 11♀; age: 69.5 ± 5.3 y; BMI: 26.4 ± 3.7 kg/m2) for 8 weeks in a group setting with 3 sessions per week, each lasting 50 minutes. Participants were randomized into either the agility group (AGI; n=12), that used the integrative multi-component training, or the traditional strength and balance group (TSB; n=15). TSB performed balance and strength exercises separately, albeit within the same session. The training of both groups progressively increased in difficulty. Outcomes were static and dynamic balance (single leg eyes open stand, Y-balance test, reactive balance), lower limb (plantar flexion and dorsal extension) and trunk flexion and extension maximum strength and rate of torque development (RTD). In addition, we tested endurance by the six-minute walk test (6MWT). We calculated linear mixed effects models for between-groups comparisons as well as effect sizes (ES) with 95 % confidence intervals. Results. Small ES in favor of AGI were found for plantar flexion strength (ES>0.18[-0.27;0.89]) and RTD (ES>0.43[-0.19;1.36]) as well as trunk extension RTD (ES=0.35[-0.05;0.75]). No other parameters showed notable between group differences. Compliance was high in both groups (AGI: 90 ± 8 % of sessions; TSB: 91 ± 7 % of sessions).Discussion. Agility-based exercise training seems at least as efficacious as traditional strength and balance training in affecting selected fall risk factors among community-dwelling healthy seniors. Especially lower limb and trunk extension explosive strength seem to benefit from the agility training.
