Assessment of Internet Banking Services Continued Use: Role of Socio-Cognitive and Relational View

10.12928/telkomnika.v16i6.4059
Mira; International Islamic University Malaysia Kartiwi , Ali; Misurata University Rfieda
Recently, continued use of information systems in general and particularly the context of internet banking has drawn increasing attention both in academic and trade literatures. However, different perspectives that determine the continued use of internet banking has been addressed. Given the long-term goal of any business entity is to increase its productivity, expand its customer base and maximize revenues, it is crucial for banks offering internet banking services to focus on encouraging their customers to continually use internet banking. While emerging attention had been given on the assessment of continued use of internet banking services from single view, little of attention were given from researchers to combine different views in a single comprehensive model. Yet, it is believe that combining different views would provide a better understanding to the issues surrounding the continued use. Drawing on the literature, this study developed a model to determine factors that influence the continued use of internet banking by combining factors from the socio-cognitive view and the relational view. Using a survey questionnaire, 450 questionnaires were distributed to users of internet banking in Libya. A number of interesting findings emerged, among others, is the lack of association between trust and perception to continue using the internet banking services in Libya.

Underwater Image De-nosing using Discrete Wavelet Transform and Pre-Whitening Filter

10.12928/telkomnika.v16i6.9236
Mohanad Najm; University of Technology Abdulwahed , Ali Kamil; University of Technology Ahmed
Image denoising and improvement are essential processes in many underwater applications. Various scientific studies, including marine science and territorial defence, require underwater exploration. When it occurs underwater, noise power spectral density is inconsistent within a certain range of frequency, and the noise autocorrelation function is not a delta function. Therefore, underwater noise is characterised as coloured noise. In this study, a novel image denoising technique is proposed using discrete wavelet transform with different basis functions and a whitening filter, which converts coloured noise characteristics to white noise prior to the denoising process. Results of the proposed method depend on the following performance measures: peak signal-to-noise ratio (PSNR) and mean squared error. The results of different wavelet bases, such as Debauchies, biorthogonal and symlet, indicate that the denoising process that uses a pre-whitening filter produces more prominent images and better PSNR values than other methods.

The precise indoor tracking system using Xbee signal strength protocol has become a potential research to the WSN applications. The main aspects for the success tracking system is accuracy performance based on location estimation. The improvement of location estimation is complicated issue, especially using RSSI with low accuracy due to the signal attenuation from multipath effect at indoor propagation. Hence, many existing research typically focused on specific methods for providing improvement schemes at tracking system area. Then, we propose hybrid filter schemes, including extended gradient filter (EGF) for filtering noise signal based distance modification, and modified extended Kalman filter (MIEKF) will be combined with trilateration for filtering the error position estimation. Using mobile cooperative tracking scenario refers to our previous work, the proposed hybrid filter scheme which is called modified iterated extended gradient Kalman filter (MIEGKF) can optimize the error estimation around 41.28% reduction with 0.63 meters MSE (mean square error) value.

Amarjeet Singh , Ramakanth Kumar P , Nagaraj G Cholli
Advances in Information and Communications Technology (ICT) have impacted the society in many ways. Be it education, healthcare, media or governance, the transformation is visible. As individual entities like education or healthcare systems have already implemented ICT to certain extent, e-governance is yet to make a significant progress even though several initiatives are undertaken. E-governance means activities like voting, administration, financial transaction etc., are enabled using automation systems.  This paper discusses one part of the e-governance; e-voting. As e-voting empowers government, there are lot of challenges in implementing the e-voting system considering security threats and confidentiality involved in it. Online voting (e-voting) needs to be deployed as more convenient, relatively secure and less resource consuming system.   E-voting system should ensure convenience for people to be able to access the system from personal or public computer with security and confidentiality. The presence of e-voting system with all the necessary security measures and convenience can be a potential solution for low voter turnout at the polls.  The presented work demonstrates an online e-voting prototype system called SecureV. The proposed model achieves specific tasks namely, maintaining the anonymity of the voter, encryption of the vote, integrity check and avoids second time voting.

Nurul Rezki Anisa , Kadek Ayu Erika , Rini Rachmawaty
Cancer has many side effects on patient’s physic and mostly on mental which may affect on their quality of life. Physically most patients feel fatigue, insomnia, anorexia, nausea, and vomit while mentally they feel emotional disturbances such as anxiety, stress, or depression. One of the methods to that appropriate to overcome both of the conditions is spiritual care. Many research found that because spiritual care associated with better wellbeing, less emotional disturbance, less substance abuse, greater social support, better health behaviours, so it has impact to longer survival periods. This research aimed to investigate nurse’s spiritual care competencies to patients with end stage cancer. This was descriptive study design employed Spiritual Care Competencies Scale (SCCS) instrument. A total sampling of 24 nurses working in Oncology department in Dr. Wahidin Sudirohusodo Hospital were recruited. This research found that there are 12 nurses (50 %) that work in oncology department have low competencies of spiritual care. Involving spiritual care is associated with better wellbeing and longer survival periods. Therefore, it is necessary to increase the competence of nurses on spiritual care in meeting the spiritual needs of patients with end stage breast cancer. A training of spiritual care can be an alternative for nurses to improve spiritual care in hospitals.

A Novel Multipath Routing Ring Protocol Adapted for WMSN

10.11591/ijeecs.v12.i3.pp1045-1053
Bennani Mohamed Taj , Mhamed M. Ait Kbir
In this paper an enhanced protocol of multipath routing ring that is suitable for transferring images by making many upgrades. First, instead of using propagation between the layers, we use certain parameters such distance and delay to pick the next node of the lower layer. Then, we used an heterogeneous network, including sensors (capture and send images) and connectors (serve as a bridge to the sink). Finally, we used  the pyramid decomposition technique. To avoid congestion, we adjust  the number of levels based on the state of the network. To verify our protocol, we used Castalia simulator to simulate the real transmission conditions. Then, we compared it with GPSR protocol and the original Multipath routing ring protocol. Our proposed protocol proves its efficiency by transferring more images with better quality (PSNR) and consuming less energy compared to other protocols.

Factors Influencing Utilization of Cervical Cancer Screening Services in Kenya: The Case of Nyeri County

10.11591/ijphs.v7i4.15013
Gichogo Agnes Wangeci , David Macharia
Globally, cervical cancer continues to be a major cause of mortality and morbidity among women with developing countries accounting for more than 86% of the deaths from the disease. In Kenya, cervical cancer ranks as the second most frequent cancer among women: regrettably, with 80% of the cases presented during the late stages of the disease when the scope of successful treatment is limited. An opportunity to prevent occurrence of cervical cancer exists through cervical cancer screening for early detection and treatment of precancerous lesions before these develop to cancer. However, only a negligible proportion of women benefit from cervical cancer screening services in developing countries, including Kenya. The purpose of this descriptive survey study was to determine the factors influencing utilization of cervical cancer screening services; and focused on the women seeking maternal and family planning services at Central Provincial General Hospital, Kenya. The study established that, as in most developing countries, utilization of cervical cancer screening services was low, regardless of the women’s education level, autonomy in decision making and even good family support. The low level of awareness on the need for screening services and the long waiting time at the clinic for those seeking the services were identified as the two key issues that negatively influenced the utilization of the screening services, It is therefore recommended that the Ministry of Health and other agencies, including individuals of good will, collaborate in designing and implementing awareness campaigns through the media and other appropriate avenues, including one-to-one encounters, targeting both men and women in the communities. It is also recommended that the male partners support their women in accessing this vital life-saving service.

A ventilation system comprising a ventilator or fan to inhale fresh air from environment surrounding enters the cabin of a car where at the same time exhale the hot air to the outside. This invention system is using solar power integrate with the ventilation system in order to stabilize the thermal condition inside the car during sunny day. The solar power is chosen as it is reasonable due to its limitless and environmental friendly source just like mentioned in the previous objective of the project. In addition, a rechargeable battery is used to power the ventilator in the absence of the alternative energy during cloudy day or has obstacle like being shaded by buildings, trees and others. It is just like an extra supply during emergency case. This may prevent the lack of power energy supply for the system. A heat sensor is used as to detect targeted (high temperature) and desired temperature (drop temperature) inside the car. It is operatively connected to a logic circuit to measure environmental factor, wherein the controller (PIC Microcontroller) utilizes the measured environmental condition to allow the power supply to activate or deactivate the ventilator.

School youth in many African countries face a range of non-infectious health risks, in addition to the infectious disease burden typical in resource-limited settings. We examined self-reported health behaviors associated with suicide ideation, school absenteeism and physical violence among secondary school students in Kampala, Uganda. We conducted a cross-sectional three-stage cluster-based survey among students aged >=15 years, and/or enrolled in forms 3–6 (grades 9-12) in 54 secondary schools in Kampala. Interview data were collected with a standardised electronic questionnaire through computer-assisted self-interviewing and results were weighted for sample design and non-response. Pearson’s chi-square and logistic regression methods were used for bivariate and multivariate analysis respectively. Bullying among female respondents was positively associated with suicide ideation (aOR=1.73). In multivariate analysis, suicidal ideation was positively associated with a lifetime exposure to illicit drug use (aOR=1.76), serious injury (aOR=1.67) or school absenteeism (aOR=1.46). School absenteeism was positively associated with serious injury (aOR=1.59), history of alcohol consumption (aOR=1.55), bullying (aOR=1.52) and suicide ideation (aOR=1.45). Serious injury (aOR=2.89), a life-time history of illicit drug use (aOR=2.65), recent history of having been bullied (aOR=2.38), physical activity (aOR=2.12), suicide ideation (aOR=1.58), school absenteeism (aOR=1.57) were associated with having been engaged in physical violence. Bullying, serious injury and illicit drug use were associated with suicidal ideation, school absenteeism and physical violence. Concerted efforts should be considered by education authorities, parents and the community to tackle these risky behaviors.
