A Mathematical Model of the Cognitive Semantics of the English Preposition on
Ruswan Dallyono, Didi Sukyadi

Universitas Pendidikan Indonesia


Abstract


A mathematical approach to linguistics provides an array of insights for quantitative description on the ways language works. This area of investigation is still underexplored, but it is actually significant for the development of mathematical models to enhance linguists’ understanding on linguistic structure. This study aims to present a mathematical analysis of how the English preposition on works under the framework of Trajector (TR) and Landmark (LM) relations (Tyler & Evans, 2003). Data were corpora taken from 10 dissertations written by American student writers. To sort the data, Ant Conc 3.4.1.0 was used to parse clauses or sentences based on the TR-LM configurations. Based on the TR-LM configurations, a mathematical model was developed to discover how these variables are quantitatively related to the number of senses produced by using a geometric representation of TR and LM. This study indicates that the relation between TRs and LMs, on the one hand, and the potential sum of senses, on the other, follows the integral function of ∑ C = ∫ TR d(LM), which means that the total number of senses of C equals the integral of TR with respect to LM. This mathematical modeling confirms the TR-LM hypothesis that every physical object has a unique sense established by their TR-LM configuration as spawned by Lakoff (1987).

Development of Property Rental Insurance Model
Sudarwanto, Lukita Ambarwati, Ibnu Hadi

Universitas Negeri Jakarta


Abstract

In this paper we developed insurance model on property rental business. We used Generalized Linear Models(GLM) to develop this model because the data on property rental matches to the characteristics of GLM.

Analysis of the model is done by looking at the relationship between the distribution functions that are most widely used in the analysis of property rental data. The models for the relations of distribution functions are: Poisson-Gamma, Poisson-Inverse Gauss, Negative Binomial-Gamma and Negative Binomial-Inverse Gauss. The relationship between distributions is seen from the root-mean-squared error (RMSE) and absolute mean error (MAE).

Simulation results show that the model formed in the case of random effects increases in standard deviation values also increases the variation value on the average estimator. This is in accordance with the condition that the addition of standard deviation means that there is an increase in the variance of the data.

Abstract

This study focuses on analyzing the theses of Mathematics Education Study Program students who are Design Research (DR) types. Thesis is analyzed with the aim to see the relationship between mathematics learning material with the characteristics of Realistic Mathematics Education. DR is a quite complex qualitative research and requires precision and creativity in preparing realistic mathematics learning. The emphasis of DR is on the process of delivering subject by teachers to students and the resulting product in the form of learning design which is part of the Hypothesis Learning Trajectory. Relational analysis in this study is in the form of error analysis as an effort to observe and describe deviations between mathematical concepts to be taught to students with mathematical contextual material to be appointed in research for every mathematical material that is described as human activity. Relational understanding produces conceptual knowledge, allows students to solve mathematical problems conceptually and can explain the strategies and steps used. From 36 DR theses, there are some learning materials which is felt to be very contextually forced, so that relational understanding is not achieved. But if it is right, not only acheived relational understanding, but also students mathematics learning outcomes increased.

Abstract

This research aims to develop a didactical design of learning about circle at junior high school, especially the relationship between central angle, length of arc, and area of segment of the circle. Developed didactical design consists of three activities obtained from three formal stages during the research process. The first stage is the analysis of the didactical situation before learning to obtain a hypothetical didactical design. Preparation of hypothetical didactical design is preceded by a preliminary study which includes the identification of obstacles student learning as well as the theoretical analysis and repersonalisasi. Identification of learning obstacle is conducted at a junior high school in South Jakarta involving 34 students of class IX by analyzing the results of the students answers on the questions provided, analyzing the results of interviews of teachers and students, as well as analyzing the textbooks used at the schools. The second stage is the analysis metapedadidaktic which is reflected in the design implementation. Design implementation is conducted at junior high school where a preliminary study done involving 36 students of class VIII. The third stage is the stage of reflection by conducting a retrospective analysis. This is done in order to obtain information for a revised design to produce empirical didactical design. The developed empirical didactical design allows for further development through the three stages of the same formal.

Abstract

A set of matrices integers modulo prime can form a finite group. This group has trivial and non-trivial subgroups. The trivial subgroup is normal clearly and for a non-trivial subgroup the normal properties will be investigated. Furthermore, if a non-trivial subgroup is a normal subgroup, then a quotient subgroup can be constructed. This paper discusses the characteristics of normality of quotient subgroup on matrices integers modulo prime. A group is constructed by matrices integers modulo prime. Here we considered some properties of this group. The order of group play an important role in this quotient subgroup. By this concept, we derive some result of normality of quotient subgroup. From this paper, it was found that the subgroup order had an effect on the normality of a quotient subgroup.

Abstract

In this study, we discussed the control of multivariate dispersion statistics for a single sample size. The control chart was developed from a multivariate control chart exponentially weighted mean square (MEWMS) with total variance (TV) as the multivariate dispersion size used. Although the MEWMS control chart has more advantages than MEWMA and MCUSUM control charts, it has limitations because it only applies to p = 3 variables. Therefore, the main focus in this study is to determine the L value as a determinant of the MEWMS control boundary width for the variable p = 4 through the simulation method. Based on historical data on controlling the wing component products of Airbus aircraft through simulations with vector mean parameters and covariance matrices, MEWMS Control Chart is quick in detecting changes in variance, while in detecting the average changes is very slow.

Abstract

Indonesia suffered a diphtheria outbreak in the late of 2017 after the last case in the 1980s. Over the years, DPT (Diphtheria Pertussis Tetanus) vaccine is believed to be the only ways of preventing diphtheria outbreaks. The Indonesian government requires all infants aged 2-4 months old to get DPT vaccine in order to get the immunity against diphtheria-causing bacteria with a single dose of vaccine on each month. The problem is when some infants do not have the complete vaccine so the effectiveness of DPT vaccine is need to be questioned. In this paper, the authors try to construct the model to see how effective the DPT vaccine for those cases. The population assumed to be closed population and consisted of SIR (Susceptible, Infected, and Recovery) population and the vaccine notated as a function of a dose that has taken by the infant. Furthermore, this model will be analyzed the stability using eigen values and basic reproduction number (R_0). The simulation is done to provide an overview of the effectiveness of the vaccine dynamically. Analysis and simulation results show that complete dose of DPT vaccine plays an effective role in reducing the spread of diphtheria.

Abstract

Variable selection is an important topic in linear regression analysis. In practice, a large number of predictors usually are introduced at the initial stage of modeling to attenuate possible modeling biases. stepwise deletion and subset selection are usually used which can be computationally expensive and ignore stochastic errors in the variable selection process. In addition, the best subset selection of variables suffers from several disadvantages, the most severe of which is its a lack of stability. In this article, penalized likelihood approaches are proposed to handle these kinds of problems. The proposed methods select variables and estimate coefficients simultaneously. Some of penalty functions are used to produce sparse solutions. Based on the RMSE and GIC criteria, it was found that the factors affecting Indonesian mathematics scores from PISA with 148 independent variables showed that the SCAD penalty function had the best performance compared to LASSO, Ridge and MCP. LASSO produces 13 important variables for the model while SCAD has 11 variables which mean that the LASSO model is more complex than SCAD. The MCP produces a simpler model with 3 important variables but produces excessive bias.Ridge penalty has a worst performance based on all criteria.

Abstract

In this paper we discuss the issue of linear algebra on the investment portfolio optimization models. It was assumed that stock returns are analyzed have a certain distribution, so that the mean and variance and covariance between the separation can be determined. Return of some stock used to form a vector averaging, and the number of shares used as the basis to form a unit vector. While the variance of each stock as well as the covariance between stocks, is used to form a covariance matrix. The investment portfolio was formed consisting of several stocks, in order to maximize the expected return and minimize risk. The portfolio optimization was performed using linear algebra approach. The result is a formula used to determine the optimum composition of the portfolio weights. The resulting formula is very useful for the analysis of the investment portfolio optimization.

Abstract

Metformin, a biguanide oral antidiabetic, is the initial treatment for patients with type 2 diabetes mellitus. Metformin is recommended either as a monotherapy or combination with the other antidiabetic agents. Some studies suggest that metformin treatments have been shown to be associated with improved the high density lipoprotein-cholesterol (HDL-C) level in type 2 diabetes mellitus by interfering with AMP-activated protein kinase (AMPK) pathway. Metformin activate AMPK that stimulates catabolic processes (glycolysis and fatty acid oxidation) and inhibits anabolic pathways (gluconeogenesis and fatty acid synthesis). This is a cross-sectional study aiming to compare HDL level in type 2 diabetic patients using metformin and non-metformin. A total of 138 patients were included in this study with mean age 59.93 (±9.49) years. In the metformin group, the median HDL-C level was 48 mg/dL, while in non-metformin group the median HDL-C level was 45 mg/dL. HDL-level in the metformin group was higher than non-metformin group but it is not statistically significant (p>0.05; Mann Whitney U test). Further studies are needed to investigate another oxidative stress parameter related to AMPK pathway.

Abstract

Anemia is a common condition found among Human Immunodeficiency Virus (HIV)-infected patients. T-cells that are infected with HIV virus can directly suppress the growth of progenitor cells in the bone marrow so that affecting the hemopoiesis resulted in anemia. These hematological abnormalities could potentially cause serious clinical implications. This study was conducted to determine the prevalence of anemia in HIV-infected patients in Bali. A total of 243 medical record data from HIV-infected patients at Wangaya Hospital Denpasar Bali and Sanjiwani Hospital Gianyar Bali between 2009 -2017 were included in analysis. Prevalence of anemia in ART-naïve patients and in patients on ART were 60.8% and 40.3%, respectively. Leucopenia and thrombocytopenia were found 8.2% and 9.4%, respectively, in ART-naïve group. While in patients with ART group leucopenia and thrombocytopenia were accounted for 6.9% and 4.3%, respectively. There was a significant difference in prevalence of anemia between ART-naïve patients and patients on ART (60.8% vs 40.3%; p < 0.05). Although the prevalence of anemia was lower in patients on ART, but anemia continues to be common in a substantial portion of HIV-infected persons. Another studies are still needed to addressing the impact of anemia on HIV-infected individuals, as well as treatment strategies and future research directions.

To ensure safety, acute toxicity testing is carried out. The test animals used were 24 female white mice, divided into 6 treatment groups. Group 1 as a control group was given aquades. Group 2-6 was given ethanol extract of guava leaves with doses of 300, 1000, 2000, 4000 and 5000 mg / KgBB. The test is carried out for 14 days where the preparation is only given once. The parameters of the study included behavioral tests on the first and 14th day, body weight every day, macropatology of vital organs and organ indexes on the 14th day. The results of all doses of extract did not show a decrease in body weight, behavior changes and macropatological changes but there were differences in organ indexes, so that Jambu Bol ethanol extract can be declared not toxic.

Keywords: acute toxicity, Syzygium malaccense

Abstract

Inflammation is a local reaction from living tissue or cells to a stimulation or injury. This anti-inflammatory test aims to determine the effect of anti-inflammatory treatment on changes in edema volume in rat’s feet after induced by carrageenan. Anti-inflammatory that is used in this research is celecoxib. Celecoxib is a non-steroidal anti-inflammatory agent that works by inhibiting selective cyclooxigenase enzymes. In this pharmacological screening test, 2 wistar strains of white rats were tested, which were weighed before anti-inflammatory administration. The rats were divided into 2 groups, namely the negative and positive control group. As for the negative control, the treatment was given 0.9% NaCl as much as 4 mL per oral, while for positive control was given celecoxib 100 mg / 55.5 ml. the volume of edema in the rat’s feet was measured using pletismometer. We found that there was no significant difference in the volume of edema between the group given 0.9% NaCl and the group given celecoxib. Therefore, we conclude that celecoxib as an anti-inflammatory agent is not able to inhibit edema in rat’s feet.

Keywords: anti-inflammatory, rats, celecoxib

Abstract

"Loloh" is a traditional Balinese drink that is believed to be able to overcome certain diseases. The Balinese people make "loloh" independently for self-consumption or trading in small-scale home industry. The making of "loloh" is usually passed down from generation to generation. So, the outstanding circulation has not been standardized and with different ingredients. "Loloh cemcem" is one of the traditional drinks from The Penglipuran Village, Bangli Regency, Bali. This study aims to conduct phytochemical tests on "loloh cemcem" in Bali, especially from Penglipuran Village. Phytochemical tests include levels of alkaloids, steroids, terpenoids, phenolics, saponins, flavonoids, and tannins. The results of this study indicate that "loloh cemcem" produced in Penglipuran Village contains moderate levels of flavonoids and terpenoids (642.88 mg/100g), containing tannins, phenols, and alkaloids. In conclusion, "loloh cemcem" has the potential to be an antibacterial, antioxidant and another benefit that still needs further investigation.

Keywords: loloh cemcem, Bali, flavonoids, terpenoids, antioxidant

Abstract

The kidneys are organs that play an important role in maintaining the balance of body fluid and removing metabolic waste products. The incidence and prevalence of kidneys disease continue to increase throughout the world. Various conditions can cause failure of kidney function. Acute kidney failure (ARF) can increase the risk of chronic kidney failure. The severity of the disease, duration, and frequency of ARF are predictive factors that are important for the patients condition. This study aims to compare the degree of kidney damage based on tubular injury scores in acute and chronic renal failure conditions using an experimental model of ischemic reperfusion injury and renal ablation. Eighteen male Swiss mice will be grouped into 3 treatment groups: the sham operation group (SO, n=6), the ischemic reperfusion injury group (IRI, n=6), and the renal ablation group (RA, n=6). Kidney tissue was stained with hematoxylin-eosin (HE) and tubular injury scores were assessed blindly. This study found that there were significant differences in tubular injury scores between the SO groups (0.43 \pm 0.49) and RA (3.6 \pm 0.70), but there were no significant differences between the SO groups (0.43 \pm 0.49) vs IRI (2.23 \pm 0.55) and IRI (2.23 \pm 0.55) vs RA (3.6 \pm 0.70). Based on the results it can be concluded that there are no differences in tubular injury scores between the ischemic reperfusion injury and renal ablation condition.
