Chen Sung Wong , Melissa Jane Chua , Kususanto Ditto Prihadi
This experimental study examined the effect of expressive writing on depressive symptoms. 86 undergraduate students were recruited from a private university to perform online positive experience writing (PEW) (n=31), negative experience (NEW) (n=32) and control topic (CW) (n=23) for three sessions in three consecutive weeks. The depressive symptoms of participants were measured at pre-treatment and post-treatment. It was hypothesized that PEW has significant greater reduction in depressive symptoms compared to NEW and CW based on broaden and build model. Nevertheless, results showed that PEW had significantly greater symptoms reduction than CW, yet there was no significant difference between PEW and NEW. The findings suggested that PEW might be potentially useful in reducing depressive symptoms among undergraduates.

10.11591/ijai.v10.i2.pp421-429
Al-Khowarizmi Al-Khowarizmi , Suherman Suherman
Simple evolving connectionist system (SECoS) is one of data mining classification techniques that recognizing data based on the tested and the training data binding. Data recognition is achieved by aligning testing data to trained data pattern. SECoS uses a feedforward neural network but its hidden layer evolves so that each input layer does not perform epoch. SECoS distance has been modified with the normalized Euclidean distance formula to reduce error in training. This paper recognizes skin cancer by classifying benign malignant skin moles images using SECoS based on parameter combinations. The skin cancer classification has learning rate 1 of 0.3, learning rate 2 of 0.3, sensitivity threshold of 0.5, error threshold of 0.1 and MAPE is 0.5184845 with developing hidden node of 23. Skin cancer recognition by applying modified SECoS algorithm is proven more acceptable. Compared to other methods, SECoS is more robust to error variations.

Structural changes that occur due to outliers may reduce the accuracy of an estimated time series model, shifting the mean distribution and causing forecast failure. This study used general-to-specific approach to detect outliers via indicator saturation approach in the local level model framework. Focusing on impulse indicator saturation, performance recorded by the suggested approach was evaluated using Monte Carlo simulations. To tackle the issue of higher number of regressors compared to the number of observations, this research utilized the split-half approach algorithm. We found that the impulse indicator saturation performance relies heavily on the size of outlier, location of outlier and number of splits in the series examined. Detection of outliers using sequential and non-sequential algorithms is the most crucial issue in this study. The sequential searching algorithm was able to outperform the non-sequential searching algorithm in eliminating the non-significant indicators based on potency and gauge. The outliers captured using impulse indicator saturation in financial times stock exchange (FTSE) United States of America (USA) shariah index correspond to the financial crisis in 2008-2009.

Due to the required different speeds and important role of direct current (DC) motors in laboratories, production factories and industrial application, speed controlling of these motors becomes an essential matter for proper operation with high efficiency and performance accuracy. This paper presents a new speed controlling technique that is based on particle swarm optimization (PSO) algorithm in the optimization process of the parameters for the fractional order proportional–integral–derivative (FOPID) controller. The FOPID is an advanced and modern controlling system in which the two more added parameters (the derivative μ and integral λ orders) are fractional rather than integer. Through the process of minimizing the fitness functions, the obtained results show that the designed controller system can excellently set the best controller parameters due to the fractions of these additional parameters. With respect to the PSO-PID controller, the simulation results for the proposed PSO-FOPID controller show performance improvements of 14%, 21%, 24.5%, 78%, and 19.3% in the values of the parameters Kp, Ki, Kd, Tr, and Ts respectively.

Genta Rizkyansah , Ety Rahayu
The high case of malaria and dengue hemorrhagic fever (DHF) in Indonesia is resolved by government of the Republic of Indonesia through human development policies in health sector. This policy is implemented through the Indonesian health program with family approach. One of the goals of Indonesian health program with family approaches is a disease control. This was descriptive qualitative research to describe the implementation of human development policies in health sector through the Indonesian health program with family approach and to confirm the obstacles in the implementation of intended policy. The results showed that the communication factor is carried out through policy socialization and focus group discussion. The disposition factor is carried out by providing technical support in the form of regulations and intensive provision to health personnel. The bureaucratic structure factor is indicated by the division of tasks and functions of each organization involved. The resource is a factor that becomes an obstacle in policy implementation. Lack of staff and budget are the reasons of program does not run optimally.

Health development is a way of increasing awareness, willingness and ability to live healthy for everyone so that an optimal degree of public health can be achieved. The purpose of knowing how the relationship between nurse competence and community health care activities. This study employed quantitative approach and correlation analysis. The population was nurses who work at public health center in Makassar City, Indonesia, however there were 118 nurses who meet the criteria in their selection. There were relationships between attitudes, skills, and competencies with the level of implementation of community health services and that there is an interaction between competence and training. The results of the competency analysis obtained an OR value of 6.429, meaning that public health center nurses who have good competence have a chance of 6.429 times to carry out community health care activities optimally. Most dominant with the implementation of public health care is the interaction between competence and training. The competence of nurses need to be improved in order to optimize the implementation of community health services through training, coaching through assigned teams, and collaborating with peers and providing support in the form of policies for rewards and sanctions such as nurse career paths.

According to World Health Organization (WHO) report an estimated 17.9 million lives are being lost each year due to cardiovascular diseases (CVDs) and is the top contributor to the death causes. 80% of the cardiovascular cases include heart attacks and strokes. This work is an effort to accurately predict the common heart diseases such as arrhythmia (ARR) and congestive heart failure (CHF) along with the normal sinus rhythm (NSR) based on the integrated model developed using continuous wavelet transform (CWT) and deep neural networks. The proposed method used in this research analyses the time-frequency features of an electrocardiogram (ECG) signal by first converting the 1D ECG signals to the 2D Scalogram images and subsequently the 2D images are being used as an input to the 2D deep neural network model-AlexNet. The reason behind converting the ECG signals to 2D images is that it is easier to extract deep features from images rather than from the raw data for training purposes in AlexNet. The dataset used for this research was obtained from Massachusetts Institute of Technology-Boston's Beth Israel Hospital (MIT-BIH) arrhythmia database, MIT-BIH normal sinus rhythm database and Beth Israel Deaconess Medical Center (BIDMC) congestive heart failure database. In this work, we have identified the best fit parameters for the AlexNet model that could successfully predict the common heart diseases with an accuracy of 98.7%. This work is also being compared with the recent research done in the field of ECG Classification for detection of heart conditions and proves to be an effective technique for the classification.

This research aimed to analyze of the relative share, frequency and correlation of restorations in both dental dentitions in childhood. The decayed, missing, and filled permanent teeth (DMFT) index is one of the most commonly used indices in epidemiologic surveys of dental caries. It quantifies dental health status based on the number of carious, missing and filled teeth. A total of 602 schoolchildren in Varna, aged 3-18 years were selected for this study. The children have a determined high caries risk DMFT index >1. The patients are divided into 16 groups according to age limit. The research takes place in the Faculty of Dental Medicine, Medical University of Varna, in the time period 2016-2018. This study is retrospective, based on medical data of the participants. Pearson's correlation and simple linear regression were used to estimate the correlation between restorations, DMF (T+t) and age. The average value of determining the level of caries of the examined groups of children is DMF (T+t) =5.46±3.95 (range 0-20). With the correlation analysis we proved a direct dependence of the ratio. The number of preventive fillings with photopolymers and composites increased with increasing age of the studied children (r=0.725; p<0.001). Their high distribution among the studied patients was established by determining the average frequency of carious lesions. The correlation analysis determined that with increasing age of the patients the number and frequency of composite restorations and sealants in the control groups increased.

One of the most critical issues of the mortality rate in the medical field in current times is breast cancer. Nowadays, a large number of men and women is facing cancer-related deaths due to the lack of early diagnosis systems and proper treatment per year. To tackle the issue, various data mining approaches have been analyzed to build an effective model that helps to identify the different stages of deadly cancers. The study successfully proposes an early cancer disease model based on five different supervised algorithms such as logistic regression (henceforth LR), decision tree (henceforth DT), random forest (henceforth RF), Support vector machine (henceforth SVM), and K-nearest neighbor (henceforth KNN). After an appropriate preprocessing of the dataset, least absolute shrinkage and selection operator (LASSO) was used for feature selection (FS) using a 10-fold cross-validation (CV) approach. Employing LASSO with 10-fold cross-validation has been a novel steps introduced in this research. Afterwards, different performance evaluation metrics were measured to show accurate predictions based on the proposed algorithms. The result indicated top accuracy was received from RF classifier, approximately 99.41% with the integration of LASSO. Finally, a comprehensive comparison was carried out on Wisconsin breast cancer (diagnostic) dataset (WBCD) together with some current works containing all features.

Golam Morshed , Hamimah Ujir , Irwandi Hipiny
In the field of consumer science, customer facial expression is often categorized either as negative or positive. Customer who portrays negative emotion to a specific product mostly means they reject the product while a customer with positive emotion is more likely to purchase the product. To observe customer emotion, many researchers have studied different perspectives and methodologies to obtain high accuracy results. Conventional neural network (CNN) is used to recognize customer spontaneous facial expressions. This paper aims to recognize customer spontaneous expressions while the customer observed certain products. We have developed a customer service system using a CNN that is trained to detect three types of facial expression, i.e. happy, sad, and neutral. Facial features are extracted together with its histogram of gradient and sliding window. The results are then compared with the existing works and it shows an achievement of 82.9% success rate on average.

We develop a precise writing survey on sequence-to-sequence learning with neural network and its models. The primary aim of this report is to enhance the knowledge of the sequence-to-sequence neural network and to locate the best way to deal with executing it. Three models are mostly used in sequence-to-sequence neural network applications, namely: recurrent neural networks (RNN), connectionist temporal classification (CTC), and attention model. The evidence we adopted in conducting this survey included utilizing the examination inquiries or research questions to determine keywords, which were used to search for bits of peer-reviewed papers, articles, or books at scholastic directories. Through introductory hunts, 790 papers, and scholarly works were found, and with the assistance of choice criteria and PRISMA methodology, the number of papers reviewed decreased to 16. Every one of the 16 articles was categorized by their contribution to each examination question, and they were broken down. At last, the examination papers experienced a quality appraisal where the subsequent range was from 83.3% to 100%. The proposed systematic review enabled us to collect, evaluate, analyze, and explore different approaches of implementing sequence-to-sequence neural network models and pointed out the most common use in machine learning. We followed a methodology that shows the potential of applying these models to real-world applications.
