Early marriage is a phenomenon that continues to occur in Indonesia, both in urban and rural areas. The latest data shows that Indonesia is ranked 7th in the world and 2nd in Southeast Asia as the country with the highest number of early marriages. In 2019, based on the results of SUSENAS, the rate of...

Stroke is the second leading cause of death globally after ischemic heart disease. Patients who survive the first stroke have a possibility to get a recurrent stroke. American Heart Association and the Indonesian Neurologist Association recommend secondary stroke prevention to minimize recurrent stroke....

Nurse managers have a bearing on the quality and safety of healthcare services, therefore understanding the factors that influence their job satisfaction can help healthcare organizations retain nurse managers. This study aims to develop an understanding of the factors that shape nurse managers’ job...

In this study, we focus on parallel programming in the purely functional language Haskell and try to analyze the execution time statically. Liquid Haskell is a program verification tool that integrates refinement types into the Haskell programming language and relies on SMT solvers for verification....

This research focuses on the detection of Structured Query Language (SQL) injection intrusion detection. This problem has gained significance due to the widespread use of SQL in different systems, as well as for the numerous versions of attacks that are performable by using this technique. This work...

This research specifically projecting output and predicting economic growth, investment needs, and additional labor by sector using labor and output data (GDP according to business fields at constant prices) during the 2001-2019 period. The analytical method used is a projection of labor based on the...

This study will analyze the cultural values and local wisdom of the Minang ethnic group contained in the short story “Tsunami” by Ismalinar. This study uses an interpretive qualitative descriptive method with a literary anthropological approach. The focus of the analysis rests on local cultural values,...

Scanning Acoustic Microscopy (SAM) images have a spatial resolution at 1 GHz comparable to conventional optical microscopy. Each pixel in the image can be analysed to determine mechanical properties, allowing their precise correlation with microstructural components of tissue. Although loss of elasticity...

Background: Even after successful treatment of aortic coarctation, a high risk of cardiovascular morbidity and mortality remains. Uncertainty exists on the factors contributing to this increased risk among others the presence of (1) a residual narrowing, leading to an additional resistance in the arterial...

Background: Increased arterial stiffness is associated with a reduced buffering capacity of the large arteries, therefore predisposing the microcirculation to increased flow and pressure pulsatility. However, increased wave reflection may be protective, by reducing the amount of pulsatility transmitted...

Background: Aortic stiffness is clinically important, but measurement can be time consuming. The ‘reflected wave transit time’ (RWTT) is thought to represent aortic stiffness and, since this can be measured quickly by brachial cuff oscillometry, could be a useful new test. This study aimed to compare...

The problem of this research is to generate electrical energy in the power plant which is located far from the load center, so it requires a transmission line in order to be distributed to the public. The purpose of this research is to find out the ratio on the primary (20,000Volt) and secondary (400Volt)...

Background: We previously described longitudinal strain gradient named bending strain (BS), along the common carotid artery (CCA) with two distinct patterns (Paini, Stroke 2007, Beaussier, Hypertension 2008): Pattern A (larger radial strain at the plaque level than at adjacent CCA) and its opposite,...

Objectives: While in young subjects, central pressure and flow peaks occur simultaneously and before time to return of reflected pressure (Tr), Tr progressively shifts towards early systole with aging, and eventually occurs before pressure peak. Consequently such parameters along with the corresponding...

Cloud computing services have not been yet deployed widely by the SMEs in Japan. Due to its many advantages, special skills and support techniques for the SMEs need to be developed in order to implement cloud computing services. A research of the relevant literature reveals that virtually no published...

A family of real Hamiltonian forms (RHF) for the special class of affine 1 + dimensional Toda field theories is constructed. Thus the method, proposed in [1] for systems with finite number of degrees of freedom is generalized to infinite-dimensional Hamiltonian systems. We show that each of these RHF...

Quantum Schrödinger equation, describing dynamical spin-interaction of two electrons with external magnetic field, is considered as an object for cybernetic research. Indeed, because of having a possibility to change external magnetic field, we can influence the interaction of particles. The algorithm...

In this paper we prove an extension of the usual freezing trick argument which can be applied to a number of quasi-exactly solvable spin models of Calogero­Sutherland type. In order to illustrate the application of this method we analyze a partially solvable spin chain presenting near-neighbors interactions...

Customer Relationship Management (CRM) plays a crucial role toward a company. These days, CRM is considered the strategic approach to the most profitable customers. However, to master such powerful tool to develop strong customer relationships, and in turn, to maximize the potential benefits, the company...
