Published: May 2023

Objetivo: Identificar “sinais e sintomas” dos capítulos da ICPC-2 inapropriadamente classificados como ativos e crónicos, verificando a sua proporção e principais capítulos. Métodos: Estudo observacional e transversal, quasi-aleatório, com características exploratórias, pela colheita de dados das consultas de todas as terças, quartas e sextas-feiras do mês de agosto de 2021, nas consultas de dois ficheiros clínicos. Fez-se a análise descritiva da lista de problemas ativos dos utentes e registo das classificações consideradas inapropriadas. Resultados: Foram avaliados os dados de 123 doentes, 52,8% do sexo feminino e com idade média de 53,3±22,4 anos. Verificámos que 45,5% dos doentes apresentavam classificações erradamente crónicas, sendo 8,2% classificações erradas. Os capítulos músculo-esquelético (16,3%), psicológico (7,3%) e os capítulos genital feminino, circulatório e geral e inespecífico (todos com 5,7%) foram os mais frequentes. Em função do género e idade, não se verificou diferença significativa, mas quanto maior era o número de classificações totais, maior era o número de classificações erradamente colocadas. Discussão: Os resultados podem significar um impacto negativo no acompanhamento do doente, na comunicação entre médicos, no aumento do tempo despendido nas consultas, por não atualização da lista de problemas, e na diminuição da credibilidade dos registos para investigação. A elevada prevalência dos sintomas músculo-esqueléticos pode levar à manutenção destes problemas como crónicos. A pandemia COVID-19 pode ser associada a um maior número de sinais e sintomas transitórios, mas classificados como ativos. Um grande número de problemas ativos pode afetar a capacidade de classificar. Conclusão: A atualização, periódica, da lista de problemas, o investimento na formação dos médicos de família na ICPC-2 e a avaliação frequente das classificações parecem atividades a desenvolver. São necessários mais estudos de validação da informação classificada nos sistemas de registo eletrónico.
Angiossarcoma cutâneo na face: um relato de caso
Authors:   UCSP Sete Rios, Martins Vanessa Simaura , Ferreira Isabel Duarte ,   UCSP Sete Rios
Published: May 2023

Introdução: O angiossarcoma é uma neoplasia vascular rara, porém, de elevada agressividade com altas taxas de recidiva local e metastização precoce. Clinicamente pode confundir-se com simples hematomas ou com doenças infeciosas e inflamatórias, dificultando o diagnóstico precoce. A biópsia cutânea assume um papel fundamental. Descrição do caso: Descreve-se o caso de um homem de 70 anos, leucodérmico, com aparecimento de mancha na face com dois meses de evolução, inicialmente na região pré-auricular e progressão para a zona periocular; sem traumatismo associado. O utente foi encaminhado para consulta de dermatologia, tendo realizado biópsia cutânea. Esta revelou angiossarcoma epitelioide avançado da face. Iniciou seguimento em consulta de oncologia médica, tendo realizado ciclo de tratamentos de quimioterapia com doxorrubicina lipossomal peguilada. Teve evolução favorável da lesão, com ausência de metastização até ao momento atual. Comentário: O reconhecimento precoce deste tipo de neoplasia torna-se essencial, devendo o médico de família apresentar uma postura diligente em relação ao aparecimento de manchas cutâneas na face, úlceras ou feridas cutâneas que não cicatrizam ao fim de quatro a seis semanas. Só o diagnóstico precoce permitirá o impacto positivo no prognóstico.

Coastal Armoring Impacts on Beaches and Sea Turtles
Authors: Monroe Martha , Carthy Ray , Hill Melissa
Published: May 2023

Close to 19.6 million people live in Florida, and 76.5% of them, or approximately 15 million, live on the coast. Florida’s coasts are attractive despite the increasing risks from sea-level rise and more frequent climatic events such as hurricanes and coastal flooding. At particular risk from these erosive events are Florida’s 825 miles of sandy beaches. Coastal armoring is a physical barrier placed with the intent of protecting structures from storm, surf, and erosion damage. This publication explains how coastal armoring works and the impacts it has on nearby beaches and sea turtle habitat.

Authors: Camp Edward , Allen Micheal S. , Ankersen Thomas T. , Barry Savanna , Mark W. Clark
Published: May 2023

Recreational fishing is especially important to Florida’s economy and ecosystems. One of the most important metrics of recreational fisheries is “effort”—defined as the number of trips taken during a time and place. Effort is so important because it directly affects fish population sustainability, economic value and market activity. But what determines fishing effort? This publication describes the mechanisms that drive fishing effort. It specifically details the processes by which management actions can directly and indirectly affect fishing effort, and how feedbacks between these actions can change effort. The information in this document is critical for people involved with management decisions, like agency personnel and their stakeholders; those wanting to explain it to others, like extension agents; directly affected stakeholders like recreational fishers and guides; or simply the general public who want to know more about recreational fisheries in Florida.

An Examination of the Perceived Need and Recommended Competencies for a Secondary School Principal Internship Program in the Seventh-day Adventist Educational System
Authors:   ,   Andrews University, Caskey Robert
Published: May 2023

Purpose. The of this study was to examine the perceived need for, the recommended competencies of, and the delivery systems suggested, for a secondary school principal internship program in the Seventh-day Adventist educational system. This study evolved from the belief that the significant turnover of principals represents a challenge for Adventist education. Because of this, the supply of qualified and experienced candidates is not available in sufficient numbers to meet the current personnel needs for secondary school administrators. The review of related literature traced the history of principal internship training in the public school system from the early 1800s to the present. A brief report of Adventist internship information was included. Method. An author generated survey was sent to four major stakeholders in the field of Adventist education: Secondary school board chairs, secondary academy principals, conference and union superintendents, and college and university professors of education in Seventh-day Adventist institutions of higher learning. The groups surveyed included the entire population of these educational leaders in the North American Division of Seventh-day Adventist education ( n = 297). The research for this study was divided into three parts: (1) The perceived need for a principal internship program; (2) the curricular components and places where they are best learned; and (3) the delivery systems recommended to make this internship available. ANOVA, Chi-square, and post hoc Student-Newman-Keuls tests were used for data analysis. Findings. Findings indicated that all four groups perceived the inclusion of a principal internship program as very important in the training of new principals. They affirmed the importance of all twenty-two competencies surveyed with the best places for learning most of these competencies to be during an internship or through job experience. They further recommended that the North American Division Office of Education in the General Conference of Seventh-day Adventists assume a leading role in the establishment of principal internship programs in cooperation with union and local conferences and Seventh-day Adventist colleges and universities.
The Empirical Development of a Curriculum on Identification of the "Tongues" of 1 Corinthians 14 Utilizing a Socio-Exegetical Approach to Interpretation
Authors:   ,   Andrews University, Hernandez Angel
Published: May 2023

Problem. The Corinthian tongues is a subject that has been extensively covered in the literature, especially in exegetical Bible commentaries, but no empirically developed curriculum for college-level instruction has been found. The purpose o f this study was to develop such a curriculum. The approach to the interpretation o f the tongues of 1 Corinthians 14 was interdisciplinary: both theological and sociological. Method. The instructional product development method formulated by Baker and Schutz and revised by Naden was used in this study. The process consisted of ten steps including; assessment of the need for a new curriculum, identification and description of the learners, formulation of measurable behavioral objectives, preparation of pre- and post-tests, development of test item criteria, development of an instructional outline, preliminary tryout of instructional product with a small group of participants, modification of instructional product based on multiple exposures to members of the target population, presentation of the developed instructional product in a regular college class setting and statistical analysis of the cognitive and affective test scores. Results. The standard of performance required that 80 percent of the participants score 80 percent or higher in the cognitive post-tests in each of the twelve behavioral objectives of the curriculum. The test results showed that the empirically developed curriculum was effective. More than 80 percent of the participants scored above 80 percent in each of the twelve behavioral objectives. The difference between the mean of the pre- and post-test scores was statistically significant and ranged from 85 to 89 percent. Modification of affect was also discernable. The results of the Likert scale instrument in pre- and post-test format showed a positive change in students' attitude and learning experience. Conclusion. The statistical analysis of the data was carried out by the use of the t-est to compare the pre- and post-test scores. The scores were correlated with the level of significance set at .05 (critical t=2.0167,t42=4.81). Therefore, it was assumed that the learners were adequately motivated and that the empirically tested method used in this study contributed to cognitive mastery of the curriculum.
An Inquiry of Governance Training, Perceptions of Board Members' Qualifications, and Board Assessments of Day Academies in the Southern Union Conference of Seventh-day Adventists
Authors:   ,   Andrews University, Higgs Nathaniel
Published: May 2023

Purpose of Study. The purpose of the study was to investigate the school boards of non-boarding secondary schools in the Southern Union regarding their governance training programs, the perceptions of the board members regarding their qualifications, and the assessments of the school boards for their effectiveness. Methodology. This study used both qualitative and quantitative approaches to collect data. Five board members and school officials were interviewed. Quantitative data were collected by a questionnaire developed by the researcher. The questionnaires were completed by 109 board members. The population consisted of all willing board members present at a scheduled board meeting. Participants were permitted to refrain from answering questions with which they felt uncomfortable. The participants responded to 11 objective questions regarding board activities and 13 subjective statements in which they selected responses from strongly agree to strongly disagree. A number of hypotheses were developed regarding the relationship between school board practices and the board members’ perceptions. These hypotheses were tested using chi-square and compared with the qualitative data. Results. Qualitative and quantitative findings revealed that there is no systematic governance training in the Southern Union even though two conferences within the union have had periodic training seminars for board members. These two conferences used the school board manual as the basis for their training. Even though the majority of school board members did not receive governance training, they perceived themselves as qualified for school board membership. They discussed some ideal qualifications for board members such as having an interest in the overall school program and having professional skills needed by the school. They also stated that they understood their roles and responsibilities and were able to make good decisions regardless of governance training. School board members revealed that there was no systematic assessment of board members' effectiveness in the Southern Union. Conclusions. Governance training is not perceived as a high priority among board members. School board assessment is not considered essential for the effectiveness of school boards in the Southern Union Conference of Seventh-day Adventists.
A Comparative Study of Giving and Volunteering Patterns Among Adults with Seventh-day Adventist and Other Christian Religious Identities
Authors:   ,   Andrews University, Stockton-Chilson Karen
Published: May 2023

Problem. In an environment that challenges the non-profit sector, including church-based organizations, to do more with less, it is important to understand the mechanisms that build and sustain two key resources-individual giving and volunteering. Research indicates that there is a great deal of variation in the extent to which individuals provide help. An integrative theoretical model is utilized to examine and compare the giving and volunteering behaviors, socialization, attitudes, reasons, and motivations of adults with Seventh-day Adventist and other Christian religious identities, with secondary consideration given to the effect of potential ethnic variations. Method. The sample (N = 1359) for this study was selected for the purpose of comparing Seventh-day Adventist adults with those of other Christian religious identities (controlled for church membership and attendance). The survey instrument utilized was the Study of Giving and Volunteering obtained from the Independent Sector. Chi-square, t tests, and analysis of variance were performed to investigate the relationships between a wide range of attitudinal, motivational, behavioral, and diversity variables and giving and volunteering behaviors. Results. Seventh-day Adventist adults (SDA) were found to be more likely to give and volunteer, and to give more extensively than those of other Christian religious identities (CRI). SDA giving rates were less labile in response to most variables than the CRI rates. While there were many small, significant differences between the SDA and CRI groups, most were small enough to be relatively unimportant. There is a strong relationship between asking people to help and their helping across all groups. The SDA group appeared to be exposed slightly more to various socialization experiences. Findings for this study, consistent with those from other studies, indicate that the most important differences between racial and ethnic identity and giving and volunteering are related to education and income. Conclusions. Findings from this explorative and comparative study support the theoretical assertions of selected portions of the integrative model of helping utilized (kinship, socialization, and cultural ethnic factors). Based on the support of the theory, best practices are suggested related to bonding, empathizing, value development and transmission, practice of caring and personal responsibility, diversifying, conflict resolution, networking, and globalization.
A Study of the Influence of Birth Order and Other Variables on Student Perceptions of School Effectiveness in a Southwestern Michigan County
Authors:   ,   Andrews University, Tobias Hamil
Published: May 2023

Problem. There is an increasing demand for quality education. In his initiative for education reform, U.S. President George W. Bush promoted the concept of no child left behind, in which he calls for more accountability. It is useful to examine student perceptions of how well the education system functions. Instead of a monolithic view, their perceptions were analyzed by birth order, gender, and ethnicity. The purpose of this study was to determine to what extent student perceptions differed by their birth order, gender, and ethnicity. Method. This study utilized a 4 x 2 x 2 (birth order by gender by ethnicity) factorial design with a survey as the method for data collection. The instrument used in collection of data was the School Effective Questionnaire (SEQ). It is an instrument consisting of 48 items on school effectiveness to which 412 respondents used a 5-point Likert scale ranging from 1, strongly disagree, to 5, strongly agree, to evaluate their schools. The instrument has seven scales. The statistical analysis was performed using a 4 x 2 x 2 ANOVA. Results. The results of this study indicated that birth order was not a significant discriminating factor. There was no significant difference in student perceptions on any of the seven dimensions in this study based on birth order. The one small exception was on the dimension, maximum opportunities for learning for African American females. Firstborn African American females had significantly higher mean scores than the last-born counterparts. There was a slight increase in the number of variables with significant difference between males and females. Males had a significantly higher mean than females on the dimension, positive school climate. On the dimension, maximum opportunities for learning, middle-born and last-born males had significantly higher means than middle-born and last-bom females. On five of the seven dimensions, Caucasians had significantly higher mean scores than African Americans. Even though African Americans had higher mean scores than Caucasians on the dimension, emphasis on basic skills, it was not significant. Conclusions. Birth order was not a significant factor in this study, except in one small sector of the population. Gender, as an independent variable, was more discriminating than birth order, but did not overwhelmingly influence student perceptions. Ethnicity, as the literature suggested, played the greatest role in influencing student perceptions.

Background and Objectives: Several methods exist to evaluate tear film, the most widely used of which is the tear break-up time (TBUT) test. This test is an invasive method that involves the use of fluorescein and stimulates the tear reflex. A chief security officer (CSO) company has added a feature called non-invasive tear film breakup time (NIBUT) to the new version of its OCT device, MS-39, which checks dry eyes without using fluorescein. In this research, the aim is to compare the results of these two methods to examine dry eyes. Methods: The evaluation starts with measuring NIBUT in MS-39. NIBUT is repeated three times in each person with an interval of 30 second. We give 30 second to rebuild tears. Then TBUT is measured three times with fluorescein using a slit lamp at 30-second intervals. Finally, the average is taken from the measurements. Results: The average results of NIBUT are 10 second and the average results of TBUT are 10 second and are equal. The distribution of NIBUT and TBUT results by the Kolmogorov-Smirnov test is normal. The distribution of TBUT results is lower than NIBUT with the Shapiro-Wilk test; That is, both methods have a normal distribution, but the TBUT method shows better findings in the field of normal distribution. Conclusion: The average of both tests is equal to each other. The distribution of findings with both methods is normal, therefore no significant difference is observed between the average findings with both methods, choosing the appropriate method for tear film is the responsibility of the doctor and the patient.

A model for the transition from disordered liquid state to the solid phase has been proposed based on establishing a correlation between the concentration of precursor clusters in a saturated solution and the features of solid phase formation. The validity of the model has been verified experimentally by simultaneously studying the oligomeric structure of lysozyme protein solutions and the peculiarities of solid phase formation from these solutions. It was shown that no solid phase is formed in the absence of precursor clusters (octamers) in solution; perfect monocrystals are formed at a small concentration of octamers; mass crystallization is observed with an increasing degree of supersaturation (and concentration of octamers); further increase in octamer concentration leads to the formation of an amorphous phase.

High-throughput RNA proximity ligation assays are molecular methods that are used to simultaneously analyze the spatial proximity of many RNAs in living cells. Their principle is based on cross-linking, fragmentation, and subsequent religation of RNAs, followed by high-throughput sequencing. The generated fragments have two different types of splits, one resulting from pre-mRNA splicing and the other formed by the ligation of spatially close RNA strands. Here, we present RNAcontacts, a universal pipeline for detecting RNARNA contacts in high-throughput RNA proximity ligation assays. RNAcontacts circumvents the inherent problem of mapping sequences with two distinct types of splits using a two-pass alignment, in which splice junctions are inferred from a control RNA-seq experiment on the first pass and then provided to the aligner as bona fide introns on the second pass. Compared to previously developed methods, our approach allows for a more sensitive detection of RNA contacts and has a higher specificity with respect to splice junctions that are present in the biological sample. RNAcontacts automatically extracts contacts, clusters their ligation points, computes the read support, and generates tracks for visualizing through the UCSC Genome Browser. The pipeline is implemented in Snakemake, a reproducible and scalable workflow management system for rapid and uniform processing of multiple datasets. RNAcontacts is a generic pipeline for the detection of RNA contacts that can be used with any proximity ligation method as long as one of the interacting partners is RNA. RNAcontacts is available via the GitHub repository https://github.com/smargasyuk/RNAcontacts/
Biomedical Nanosystems for in vivo Detoxification: From Passive Delivery Systems to Functional Nanodevices and Nanorobots

The problem of low efficiency of nanotherapeutic drugs challenges the creation of new alternative biomedical nanosystems known as robotic nanodevices. In addition to encapsulating properties, nanodevices can perform different biomedical functions, such as precision surgery, in vivo detection and imaging, biosensing, targeted delivery, and, more recently, detoxification of endogenous and xenobiotic compounds. Nanodevices for detoxification are aimed at removing toxic molecules from biological tissues, using a chemical- and/or enzyme-containing nanocarrier for the toxicant to diffuse inside the nanobody. This strategy is opposite to drug delivery systems that focus on encapsulating drugs and releasing them under the influence of external factors. The review describes various kinds of nanodevices intended for detoxification that differ by the type of poisoning treatment they provide, as well as the type of materials and toxicants. The final part of the review is devoted to enzyme nanosystems, an emerging area of research that provides fast and effective neutralization of toxins in vivo.
An Energy-Efficient Routing Protocol for Wireless Sensor Networks Using AI Techniques

Published: May 2023

In the past many years different types of routing protocols, single-path and Multipath, have been designed for wireless sensor networks. We have also found various multipath routing protocols available that send similar data to the base station via multiple paths to increase reliability. We have found that a new simulation environment Castalia is developed based on OMNET++. They have provided implementation of Multipath rings routing protocol. We found that it is based on a technique called Synopsis Diffusion. We observed that although the implementation of the protocol is there, a detailed understanding of the technique is not available in the literature. Hence, in this paper, we have discussed the Multipath rings routing protocol for wireless sensor networks implemented by Castalia Simulator. Here, we have also, evaluated the performance (and hence verified its working) of the Multipath rings routing protocol through simulation. We have taken a view that the Multipath rings routing protocol can route the packet from source to Sink via multiple paths so the network becomes more robust and fault tolerant than the Single path routing. Simulation results also show that the Multipath rings routing protocol is more robust than the Proposed EE routing technique.
Text Encryption Using Improving Key of Hi Sec Algorithm Using Rubik's Cube
Authors: Israa Shihab Ahmed
Published: May 2023

Several techniques have been developed to generate keys using Rubik's Cube, which has been researched as a potential source of randomness for cryptography. This study suggests an innovative technique for creating a key for the Hi Sec algorithm using a Rubik's Cube image. The process entails creating a binary key for text encryption by leveraging the cube's color information. The Rubik's Cube principle, which includes choosing a subset of cube faces to generate the key, serves as the foundation for the key creation process. Experimental findings indicate that the proposed approach can produce safe keys that are resilient to a variety of assaults. The technique offers a fresh and effective way to generate keys for the Hi Sec algorithm, which may be used in several secure communication systems. The proposed method was programmed in VisualBaic.Net 2012.
