PurposeThis study aimed to compare the early hematological dynamics and acute toxicities between proton beam craniospinal irradiation (PrCSI) and photon beam craniospinal irradiation (PhCSI) for pediatric brain tumors.Materials and Methods We retrospectively reviewed patients with pediatric brain tumors who received craniospinal irradiation (CSI). The average change in hemoglobin levels (ΔHbavg), absolute lymphocyte counts (ΔALCavg), and platelet counts (ΔPLTavg) from baseline values was evaluated and compared between the PrCSI and PhCSI groups at 1 and 2 weeks after the initiation of CSI, 1 week before and at the end of radiotherapy, and 3-4 weeks after the completion of radiotherapy using t test and mixed-model analysis.Results The PrCSI and PhCSI groups consisted of 36 and 30 patients, respectively. There were no significant differences in ΔHbavg between the two groups at any timepoint. However, ΔALCavg and ΔPLTavg were significantly lower in the PhCSI group than in PrCSI group at every timepoint, demonstrating that PrCSI resulted in a significantly lower rate of decline and better recovery of absolute lymphocyte and platelet counts. The rate of grade 3 acute anemia was significantly lower in the PrCSI group than in in the PhCSI group.Conclusion PrCSI showed a lower rate of decline and better recovery of absolute lymphocyte and platelet counts than PhCSI in the CSI for pediatric brain tumors. Grade 3 acute anemia was significantly less frequent in the PrCSI group than in the PhCSI group. Further large-scale studies are warranted to confirm these results.

Published: October 2021

Pond bottom soil quality is an interesting area to assess environmental impact of aquaculture. Aim of the present study was, therefore, to investigate effects of fish culture on quality of pond bottom soil. Ten excavated earthen ponds located in Lahore, Pakistan were divided into two groups; Group1: 23-32 years old and Group 2: 8-20 years old ponds. Mechanical and chemical methods were used to study particle size distribution and physico-chemical attributes of soil respectively. Surface sediment of ponds contained higher sand and lower clay content than that of deeper soil layers in both groups. pH of the soil was higher than 7.0 that ruled out the necessity to lime soil for neutralizing acidity. Salinity of surface soil was found to be significantly high (P<.05) compared to that of deeper layers. Organic carbon in surface soil of Group 1 ponds (3.35%) was significantly higher (P<.05) than that of Group 2 ponds (2.60%). Available phosphorous represented only 1-10% of total soil phosphorous. An interactive effect of pond age and soil depth was found on soil clay and electrical conductivity through factorial analysis. Results led to the conclusion that regular removal of sediment can maintain original quality of bottom soil.

Published: October 2021

The Black Sea anchovy (Engraulis encrasicolus ponticus) is not only the top commercial species with around 250 thousand tonnes of annual catch but a key species of the Black Sea ecosystem facilitating the flow of energy within the food chain. The General Fisheries Commission for the Mediterranean has assessed the status of its stock for the Mediterranean since 2013. Underlining the shortcomings in the assessments, the commission has recommended diversifying and strengthening the data used and promote methods that provide biomass and abundance indices, such as hydroacoustics. This study aims to help fulfill the underlined deficiency by pursuing the implementation of the hydro-acoustic research surveys in the Turkish Black Sea EEZ. The survey was carried in November/December 2020, when the anchovies were accumulated within the Turkish EEZ, and cruise tracks were designed to cover the distribution areas of juvenile (0-year-old) and adult (Age 1 and over) anchovies displaying different distribution patterns within the Turkish EEZ in winter. The results show that the stock size is noticeably smaller than in previous years. Pelagic trawl sampling conducted alongside the acoustic data collection to estimate the size composition of anchovies indicated that the juvenile fish constitute an alarmingly large part of the overwintering stock.

In this paper we compare simulation results on a differential pair circuit using a CNTFET model, already proposed by us, with the result obtained using Stanford model. We study the case of differential pair with differential input and single ended output as core of a 50 GHz amplifier for mm waves band. We consider the case of a CNTFET having a single CNT tube with indices (19,0) and 25 nm long. For this circuit we present result for its main parameters: gain, input impedance, output impedance, noise and distortion. Since the Stanford model includes fixed capacitance, for comparison we applied the same capacitance on our model. Since this capacitances dominate the high frequency cut, results are not much different, except for the lack of noise modelling in the Stanford model.

The fast advancement of technology on a daily basis encourages the tourist industry to evolve and convert into a digital idea. The tourist hamlet as a tourism destination is the subject of this study, as is its culture and distinctiveness. The Indonesian country has 1734 tourist villages, but only a few are controlled and well maintained. While the tourist villages were expected to provide economic growth for the village community, the reality was that they provided only a few benefits and did not spread to all regions of the village. This study will concentrate on developing a tourist model using a digital economy strategy in order to demonstrate the idea of digital transformation. This model will assist the government in monitoring, controlling, and financing tourism activities, as well as in promoting and distributing products/services without the involvement of third parties, so that the government's enthusiasm for developing tourist villages from village communities to rural communities can be realized

Published: October 2021

Cyberbullying is an act that violates where this crime is committed on social media, e.g. the Twitter application. This action is difficult to detect, thus someone has to report the case before detection. Identification of cyberbullying tweets aims to classify tweets containing the bullying content. Several studies gave output results in the identification of whether the tweet is positive or negative, or bully or not. It can be confusing when analyzing the classification results as it only results in two classes. In this research, by using the conception of text mining Naïve Bayes, the model that can categorize into more detail was developed. It does not only categorize the contents are bullying or not, however it can classify the contents into five detail categories. The classification process done based on the dataset and label where the schema to build dataset was proposed scientifically from this study. The contribution of this research is to offer the algorithm to collect and label the Indonesian language dataset and then classify the types of sarcasm, namely animal, psychology and stupidity, disabled person, attitude, and general bullying. The research hypothesis is that analysis from the classification results can be improved by classifying bully content into the five classes. Dataset was collected by the researcher and labelling was done manually based on study literature. The result proves the model can use to classify cyberbullying content in social media with 99.15% accuracy.

Published: October 2021

El objetivo de este trabajo es construir un indicador compuesto, consistente y confiable, para evaluar las condiciones fisiológicas de un grupo de pacientes bajo tratamiento de hemodiálisis. Los indicadores compuestos, desarrollados a partir de indicadores individuales, tienen la ventaja de poder interpretarse rápidamente y dar a quien toma las decisiones una orientación sobre los procedimientos a seguir.
El propósito es proporcionar un indicador de gestión que ayude a optimizar el funcionamiento del servicio hospitalario para brindar a los pacientes el máximo de cuidado. Para formalizar el indicador compuesto se consideraron los laboratorios clínicos realizados a los pacientes antes del proceso de hemodiálisis.
La idea central del estudio es realizar un ranking de los pacientes sustentado en los criterios que fundamentan las condiciones fisiológicas de cada uno de ellos. El estudio se realizó en un importante hospital de la ciudad de Córdoba, Argentina.
Para resolver el problema se aplicó el método multicriterio de apoyo a las decisiones Reference Ideal Method. Se han propuesto modificaciones a la técnica originaria para que sea posible trabajar con varios intervalos ideales de referencia en un mismo criterio. La consulta a expertos para determinar los criterios de la evaluación y los pesos relativos asignados a cada uno de ellos se cumplimentó respetando las formalidades del método de indagación Delphi.

Este trabajo presenta el análisis y valoración de seguros de vida individual, temporarios y con prima nivelada, a partir de la analogía de las reglas del contrato con las de una opción exótica, en particular una digital pura o pulso, también conocida como cash or nothing. Se presentan diversos casos que parten de un asegurado con atributos cambiantes (edad y género) y se testea la sensibilidad a diferentes formas funcionales para la distribución de probabilidad de la variable estocástica, tiempo de vida restante al momento de contratar el seguro, mediante simulaciones de Monte Carlo. En un conjunto de casos la función de probabilidad se ajusta de manera personalizada a datos recientes de la República Argentina para estimar las probabilidades de ejercicio de la opción, variable que resulta sensiblemente crítica para la estimación del valor del contrato. Los valores de mercado de las primas de las pólizas comparables superan en más del doble al valor teórico encontrado para la opción exótica, ante iguales condiciones del contrato en cuanto a monto asegurado, duración y condiciones demográficas del individuo.

Application of GAP (groups, algorithms and programming) system to stereoisograms for characterizing RS-stereoisomers of cubane derivatives
Authors:   Shonan Institute of Chemoinformatics and Mathematical Chemistry, Japan, Fujita Shinsaku
Published: October 2021

The PCI (Partial-Cycle-Index) method of Fujita’s USCI (Unit-Subduced-CycleIndex) approach has been applied to symmetry-itemized enumerations of cubane derivatives, where groups for specifying three-aspects of symmetry, i.e., the point group for chirality/achirality, the RS-stereogenic group for RS-stereogenicity/RS-astereogenicity, and the LR-permutation group for sclerality/ascrelarity are considered as the subgroups of the RS-stereoisomeric group . Five types of stereoisograms are adopted as diagrammatical expressions of , after combined-permutation representations (CPR) are created as new tools for treating various groups according to Fujita’s stereoisogram approach. The use of CPRs under the GAP (Groups, Algorithms and Programming) system has provided new GAP functions for promoting symmetry-itemized enumerations. The type indices for characterizing stereoisograms (e.g., for a type-V stereoisogram) have been sophisticated into RS-stereoisomeric indices (e.g., for a cubane derivative with the composition ). The type-V stereoisograms for cubane derivatives with the composition are discussed under extended pseudoasymmetry as a new concept.
Evaluation of classification performances of minimum spanning trees by 13 different metrics
Authors:   University of Milano-Bicocca, Todeschini Roberto , Valsecchi Cecile
Published: October 2021

Minimum Spanning Tree (MST) is a well-known clustering algorithm that provides a graphical tree representation of the objects in a data set by exploiting local information to link each pair of similar objects. The a-posteriori analysis of this tree in terms of nodes and edges provides the basis to derive simple classifiers, namely semi-supervised classification approaches based on the minimum spanning tree approach. In this work, we propose different metrics to evaluate the MST ability to group objects of the same a-priori known classes. The classification capability of the proposed approach, using 13 different distance measures, was compared with that of classical supervised classification approaches such as N-Nearest Neighbour (N3), Binned Nearest Neighbour (BNN), Partial Least SquaresDiscriminant Analysis (PLS-DA), K-Nearest Neighbour (KNN), exponentially weighted K-Nearest Neighbour (wKNN) and Support Vector Machine with radial functions (SVMRBF) on 31 data sets. The proposed approach resulted to be competitive and comparable with the considered classical supervised classification methods. Finally, we analysed the role of the 13 different measures in terms of performance and percentage of not-assigned objects.

With so many people now wearing mobile devices with sensors (such as smartphones), utilizing the immense capabilities of these business mobility goods has become a prospective skill to significant behavioural and ecological sensors. A potential challenge for pervasive context assessment is opportunistic sensing, has been effectively used to a wide range of applications. The sensor cloud combines cloud technology with a wireless sensor, resulting in a scalable and cost-effective computing platform for real-time applications. Because the sensor's battery power is limited and the data centre’s servers consume a significant amount of energy to supply storage, a sensor cloud must be energy efficient. This study provides a Fog-based semantic for enabling these kinds of technologies quickly and successfully. The suggested structure is comprised of fundamental algorithms to help set up and coordinate the fog sensing jobs. It creates effective multihop routes for coordinating relevant devices and transporting acquired sensory data to fog sinks. It was claimed that energy-efficient sensor cloud approaches were categorized into different groups and that each technology was examined using numerous characteristics. The outcomes of a series of thorough test simulation in NS3 to define the practicality of the created console, as well as the proportion of each parameter utilized for each technology, are computed.

UPAYA MENUMBUHKAN BUDAYA LITERASI DI KALANGAN MAHASISWA
Authors: Jalaludin Jalaludin
Published: October 2021

Sebutan “kutu buku” seolah-olah kebiasaan membaca sebagai hal yang aneh. Bahkan di kalangan mahasiswa, anak yang rajin membaca justru diolok-olok dan dipandang sebagai mahasiswa yang kurang gaul. Persepsi inilah yang sesungguhnya telah berakibat buruk terhadap sistem pendidikan di tanah air yang menjurus kepada rendahnya budaya literasi, tidak terkecuali di kalangan mahasiswa dan umumnya masyarakat Indonesia. Beberapa hal yang menjadikan rendahnya budaya literasi di Indonesia antara lain, tingkat pendidikan masyarakat, malas membaca, minimnya akses dalam membaca. Ini disebabkan sedikitnya perpustakaan, harga buku yang cenderung tak terjangkau oleh daya beli masyarakat dan pemamfaatan teknologi yang tidak tepat, sehingga hanya sedikit yang mampu menuliskan pengetahuan yang diperoleh dari membaca.

Dynamics of leadership and teacher effectiveness in universities in north-central Nigeria
Authors: Stephen Gyang Theresa
Published: October 2021

The study examined the dynamics of leadership and teacher effectiveness in Universities. The uninspired roles played by university leadership for societal development seem to implicate the qualities of teacher effectiveness in teaching, research and community service. Teachers’ performance appears lower than expected as personal observation has shown in most institutions in Nigeria. The study adopted a correlational survey design. The sample for the study consisted of one thousand six hundred and thirty-three (1, 633) academic staff members out of the population of eight thousand six hundred and thirty-four (8, 634) academic staff members working in the thirteen public Universities in North-central Nigeria as at April 2019. The data were collected through a structured questionnaire tagged: Dynamics of Leadership and Teachers’ Effectiveness Questionnaire (DLTEQ) confirmed to be of 0.86 reliability coefficient. The data collected were analysed using mean and standard deviation to answer the research questions, and the hypotheses were tested using the Pearson Product Moment Correlation Coefficient (Pearson r) at a 0.05 significance level. The major findings of the study revealed that the dynamics of leadership are largely lacking; teachers’ effectiveness in teaching and research are lower, and there is a significant relationship between dynamics of leadership and teachers’ effectiveness in universities. It is recommended among others that University leaders should ensure the use of quality dynamic leadership skills to have a sense of mission with good interpersonal relationships, monitor frequently, et cetera considering the situation of the work environment, and the National University Commission should set urgent dynamic leadership training for University leaders through seminars and workshops for teacher effectiveness.
Challenges and coping strategies of student mothers of ‘ucc’ college of distance education: The case of the Cape Coast centre

Published: October 2021

Student mothers in distance education programmes in Ghana have to combine family roles with work and academic pursuits. Therefore, this study sought to find out the challenges and coping strategies of student mothers at the College of Distance Education (CoDE) of the University of Cape Coast (UCC), Cape Coast Centre. In this descriptive survey, a questionnaire was used to collect data from 175 conveniently sampled student mothers attending classes at Cape Coast Centre, CoDE, UCC. The data collected was analysed using frequencies, percentages, means and standard deviations. The findings from the data gleaned that majority of student mothers (a minimum of 71%) performed a lot of laborious non-academic activities daily in their homes and the combination of these roles with their academics pose a negative high effect on their family lives and academics. Unfortunately, the coping strategies they employed were, to a large extent, ineffective. Thus, student mothers have inevitable academic impediments that emanate from the non-academic activities they perform at home, posing challenges to their academic pursuit. Therefore, CoDE, in collaboration with the Counselling Unit of the University of Cape Coast should provide counselling services to these student mothers to be aware of the academic challenges and ways to effectively navigate these challenges to be successful.

Authors: Agyeman-Nyarko Phyllis
Published: October 2021

The study assessed the differences in Principals’ instructional leadership behaviours based on experiences (number of years served as Principal) in Colleges of Education (CsOE) in Ghana using the descriptive survey design. The population of the study was all Principals from the forty-two (42) CsOE in Ghana. The study sampled thirty-six (36) Principals using the simple random sampling technique. The Principal Instructional Leadership Behaviours (PILB) scale was used to collect data. Means, standard deviations and the one-way ANOVA were used to analyse the research question and to test for the hypothesis respectively. The study revealed that Principals often promote collaboration among tutors, provide support for tutors’ work, provide an induction for new tutors and promote in-service training for tutors in CsOE in Ghana. However, the findings from the study gleaned that supervision of instruction was sometimes exhibited by Principals in CsOE in Ghana. The study further found that Principals’ instructional leadership behaviours differed when they were grouped according to their experience. It was concluded that though Principals provide instructional leadership for the benefit of tutors and the general teaching and learning climate of CsOE in Ghana, their instructional supervision should be improved. The study yielded a central recommendation that Principals of CsOE need to improve upon their supervision of instruction to promote the continuous professional development of tutors.
