LA COMUNIDAD DE LOS JURISTAS
Authors: Antillón Montealegre Walter , Muñoz Muñoz Marcela
Published: June 2023

Apoyados en la ‘comunidad jurídica’ de su tiempo, los jurisconsultos republicanos inventaron la Iurisprudentia y con ella lograron prolongar prodigiosamente, al interior de Roma, durante varios siglos, un orden tentativamente justo y racional entre la barbarie del pasado monárquico y la barbarie del futuro imperial.  Pero su invento, la Iurisprudentia, sobrevivió al Imperio Romano, fecundó la cultura jurídica occidental y renace incesantemente, como el Ave Fénix, en el pensamiento de los juristas.
Los Mecanismos Juridicos de Participación Ciudadana en la Aprobación de Nuevas Terapias en Costa Rica.
Authors: Mora Freddy Arias , Quesada Valeria Rodriguez
Published: June 2023

En el presente trabajo se analiza la participación ciudadana para la aprobación de nuevas terapias en Costa Rica en el ordenamiento jurídico costarricense. En primera instancia, realiza una conceptualización sobre el rol de los pacientes en una democracia sanitaria. Se contrasta la situación costarricense con dos agencias de referencia: la Agencia Europea de Medicamentos (EMA) y la Administración de Alimentos y Medicamentos de los Estados Unidos (FDA), a partir del Modelo de Producción Social de la Salud y los mecanismos jurídicos y técnicos para la aprobación de nuevas terapias en Costa Rica, por medio del Consejo Técnico de Inscripción de Medicamentos del Ministerio de Salud y el Comité Central de Farmacoterapia de la Caja Costarricense de Seguro Social. Se concluye que en Costa Rica no existe normativa que asegure o garantice la participación ciudadana en los procesos de autorización de nuevas terapias, e incluso existe poca transparencia en decisiones que afectan la salud de la población del país.
LA CONSTITUCIONALIZACIÓN DEL DERECHO HUMANO A LA SALUD EN LATINOAMÉRICA
Authors: Arias Mora Freddy , Xatruch Ovares Juan Pablo
Published: June 2023

En Latinoamérica los estados se han obligado a través de sus ordenamientos jurídicos a garantizar, promover y proteger el derecho a la salud, incluso la mayoría lo incluyen en sus Cartas Magnas. El presente análisis plantea la situación de diversos países latinoamericanos que han positivizado el derecho a la salud en su normativa interna, además que contienen mecanismos para accionar judicialmente en procura de defender el derecho. Se analiza el caso de México, Guatemala, Brasil, Argentina y Costa Rica. En estos países las instancias responsables de la prestación del servicio de salud irrespetan constantemente el derecho de las personas, lo cual ha generado que exista un aumento del uso de herramientas judiciales para hacer valer su derecho, debido a la ineficacia de las vías administrativas. Teniendo incluso que llegar a la propia Corte Interamericana de Derechos humanos en procura de tutelar su derecho a la salud. Es necesario que los sistemas de salud procuren establezcan mecanismos que detecten las violaciones de derechos humanos y tomen medidas correctivas.
QUINCE RAZONES PARA ESTUDIAR DERECHO ROMANO EN EL SIGLO XXI: REFLEXIONES DESDE LA “CULTURA JURÍDICA” DE UN ADVENEDIZO
Authors: Argüello Rojas Luis Mariano
Published: June 2023

La presente reflexión contraría abiertamente aquella obstinada corriente universitaria que en Costa Rica mira al Derecho Romano con desprecio y que, sin mayores bases de sustento, lo considera como una materia que consiste en poco menos que una pérdida de tiempo. Teniendo presente el destino de soledad que en ocasiones acompaña al jurista de buena fe, estas heterogéneas razones se han cimentado a contracorriente en procura de negar con fundamentos el eco de voces que con afán modernista —o quizá: populista— alzan sus pérfidas banderas pretendiendo publicitar como irrelevante todo lo heredado

Uso del software Balística para analizar un caso del volcán Turrialba (Costa Rica)
Authors: Brenes-André José
Published: June 2023

Con la ayuda del software BALÍSTICA, desarrollado por el autor, fue posible analizar la posible trayectoria de un bloque balístico eyectado el 29 octubre del 2014, que impactó el puesto de guardaparques del volcán Turrialba, causando destrozos que pudieron ser mortales. En el análisis se pudo incorporar el concepto de que, en las primeras decenas de metros de recorrido, el fragmento fue arrastrado por la nube de gas y ceniza por lo que se mueve como un proyectil ideal. El resto del recorrido se supuso fue hecho en un régimen Newtoniano con coeficiente de arrastre Cd constante. Ambas etapas estuvieron afectadas por la asimetría del cráter. Bajo estas condiciones se calculó 125 ms-1 y 65° para la velocidad y ángulo de salida, de 83,3 ms-1 y 74,6° para la velocidad y ángulo de llegada, con un tiempo de vuelo 20,3 s (utilizando un Cd = 0,42 asociado a una semiesfera). Al final se incluyen unas recomendaciones generales sobre cómo construir los próximos refugios de manera que se reduzca el riego tanto de los guardaparques como de los visitantes.

Published: June 2023

En esta investigación se identificó el periodo fundamental del suelo (Tf) en 185 sitios ubicados en el Cantón Central de San José (CCSJ) utilizando la técnica de razón espectral H/V. Los periodos fundamentales fueron obtenidos a partir de mediciones en cada sitio. En cerca del 85 % de los sitios donde se aplicó el método H/V se logró una identificación clara del periodo fundamental, que corresponde al pico de mayor amplitud en el gráfico de H/V. Al presentarse los resultados de Tf en mapas, se observan claramente 3 zonas, donde los periodos promedio para la zona 1 son de 0.5 s con valores extremos de 0.1 a 0.9 s, para la zona 2 inferiores a 0.3 s y para la zona 3 variables, entre 0.1 y 0.4 s. El periodo fundamental medido máximo se ubica como un punto aislado en el sector suroeste del distrito de Mata Redonda y tiene un valor superior a 0.8 s. Se estimó el parámetro Vs30 y se clasificó el sitio según el Código Sísmico de Costa Rica, ambos a partir de correlaciones establecidas según Pinzón et al. (2021).

Published: June 2023

Objective: To evaluate the association between maternal hemoglobin concentrations and incomplete abortion.Methods: An analytic, cross-sectional study with consecutive sampling method was conducted using medical records of 45 pregnant women aged 18 – 35 years old visiting the Obstetrics and Gynecology Department of Dr. Hasan Sadikin General Hospital, Bandung, Indonesia from January 1, 2017 to December 31, 2019. Participants were grouped into incomplete abortion and non-abortion groups.Results: Maternal characteristics in the incomplete abortion group showed that the majority of pregnant women in this group were 25.58 years of age, non-anemic (n=37, 82.22%), had no previous spontaneous abortion (n=40, 88.89%), and were nulliparous (n=25, 55.55%) with a mean interpregnancy interval of 4.03 years. The characteristics in both incomplete abortion group and non-abortion group were homogenous in the level of anemia (p-value=0.380), previous spontaneous abortion (p-value=1.00), and interpregnancy intervals (p-value=0.667). The mean hemoglobin concentration for the incomplete abortion group was 11.81 gr/dL (95% CI, 11.30 to 12.26). Heterogenous data was found in age (p-value=<0.001) and parity (p-value=0.002). Parity was a strong confounder, causing the hemoglobin concentration insignificantly associated to incomplete abortion (p-value=0.884).Conclusion: No statistically significant association is found between hemoglobin concentration and incomplete abortion. Most women with incomplete abortion are around 25 years old, nulliparous, non-anemic with a mean hemoglobin concentration of 11.81 gr/dL with no history of previous abortion, and a rather secure interpregnancy intervals.

Published: June 2023

Penelitian ini berfokus pada penggunaan skor DELTA CRP dan SOFA dalam memprediksi prognosis pada pasien ICU. Penelitian observasional kohort digunakan sebagai desain. Penelitian dilakukan di RSUP Dr. Sardjito periode Februari–Juli 2019. Sampel dipilih menggunakan teknik pengambilan sampel berturut-turut. Para peneliti mengumpulkan 32 responden dengan sepsis dan syok sepsis yang dirawat di ICU berdasarkan kondisi ini. Skor area under curve (AUC) delta CRP menunjukkan >0,7 (0,780;CI 95%: 0,58–0,97) dengan cut-off 3 (sensitivitas=53,8%, spesifisitas=91%), menyiratkan bahwa CRP delta dapat menunjukkan keadaan pasien sepsis dan syok septik yang memburuk, tetapi kurang sensitif untuk memprediksi kematian. Sementara itu, skor AUC of SOFA >0,7 (0,787; 95% CI: 0,58–0,98) pada hari ke-0 dengan cut-off 8,5 (sensitivitas=76,9%, spesifisitas=81,8%), dan 0,836 (CI 95%: 0,67–0,99) pada hari ke-2 dengan cut-off 6 (sensitivitas=84,6%, spesifisitas=72,7%). Hal ini menunjukkan bahwa skor SOFA dapat memprediksi tingkat kematian prognostik pada pasien yang didiagnosis sepsis dan syok septik di ICU. Baik skor delta CRP dan SOFA memiliki nilai AUC lebih besar dari 0,7, tetapi hanya delta CRP yang memiliki sensitivitas rendah sebagai prognostik kematian.

Authors: Benedek Marton , Biro Peter , Johnson Matthew , Paulusma Daniel , Ye Xin
Published: June 2023

Matching games naturally generalize assignment games, a well-known class of cooperative games. Interest in matching games has grown recently due to some breakthrough results and new applications. This state-of-the-art survey provides an overview of matching games and extensions, such as b-matching games and partitioned matching games; the latter originating from the emerging area of international kidney exchange. In this survey we focus on computational complexity aspects of various game-theoretical solution concepts, such as the core, nucleolus and Shapley value, when the input is restricted to a matching game or one of its variants.
EXPERIMENTAL ANALYSIS OF PID-CONTROLLED HEAT RECOVERY AIR HANDLING UNIT BY MACHINE LEARNING METHODS
Authors: Budak Erhan , Korkmaz Murat , Doğan Ayhan , Ceylan İlhan
Published: June 2023

The need for energy continues to increase rapidly all over the world day by day. The demand for energy is rising in developing economies and industrial production areas in these economies. Energy is one of the essential inputs for business areas. Today, most energy is used in buildings for the purpose of heating, cooling, and air conditioning. The problem with air-conditioning systems is that the airflow remains constant despite the change in the number of people in the interior areas. The interest of this paper is to explore how the thermal comfort and air quality of a cloud-based proportional integral derivative (PID)-controlled plate heat exchanger recovery air handling unit were investigated in a classroom environment. Depending on the variables of the temperature and humidity of the outdoor environment, the number of students in the classroom, and the amount of fresh air sent to the indoor environment, the temperature, humidity, and air quality values of the indoor environment were controlled. In line with the data received from the cloud-based system, indoor temperature and indoor air quality values were analyzed by using the machine learning methods separately, that is, support vector machine (SVM), Gauss process regression (GPR), regression trees (RT), and ensembles of trees (ET). In the experiment set, the class's CO2, temperature, and relative humidity values were compared with the R2 values by machine learning methods when the air handling unit was started. As a result of the comparison, the R2 value of the amount of CO2 was obtained from the GPR method at 99%, the temperature amount from the GPR method at 93%, and the relative humidity amount from the GPR method at 98%.
Sustainable cementitious materials: exploring alkali-activated binders
Authors: Goufi Nourredine , Kaid Nouria , Kerdal Djamel El Ddine , Idir Rachida
Published: June 2023

The potential use of natural pozzolan (NP) from Algeria for the production of a new alkali-activated binder (AAB) was investigated. CEM II 42.5 cement was added to the NP as a calcium resource. The mixtures were then activated by sodium hydroxide, sodium sulfate and sodium silicate at concentrations of 3, 7 and 11%, respectively. The chemical activators were added in liquid or solid forms to develop a one-part alkali-activated material. X-ray diffraction, thermogravimetric analysis/differential thermal analysis and scanning electron microscopy/energy dispersive spectroscopy were used to assess the microstructure and elemental composition of the hydration products. Properties such as the consistency and setting times of various mixtures and compressive strengths of AAB specimens cured for 7, 28, 90 and 420 days were determined. The ratio of cement carbon dioxide footprint to strength ratio is suggested as an indicator to highlight the environmental contributions of the AABs. The AABs showed different strength levels depending on the activator type and its concentration. A maximum 28-day compressive strength of 25.2 MPa was achieved with 7% sodium silicate. High early strength development was also noted; more than 50% of the strength could be achieved within 7 days. Finally, an environmental advantage was noted, as the Global Warming Potential of the AABs could be 70% lower than that of ordinary Portland cement.

Authors: Nazeer Mudasir , Kapoor Kanish , Singh Surinder Pal
Published: June 2023

The performance of pervious concrete (PC) was observed for different cloggers, namely, sand, clay and their combination (S&C). The clogging potential of PC was determined by simulating natural clogging conditions on cylindrical specimens with a sediment load of 50, 150 and 200 g for sand, clay and combined S&C-laden runoff cycles, respectively. Furthermore, this study was extended to observe the recovery rate of infiltration using rehabilitation techniques such as vacuuming, pressure washing and vacuuming followed by pressure washing. It was observed from the results that an S&C clogger shows overall critical results of clogging as 80% of the clogging was observed in three to four cycles. Furthermore, sand showed 80% of clogging after seven cycles, and clay after eight. Among rehabilitation techniques, vacuuming shows an average recovery rate of 52, 75 and 76% for clay, sand and S&C cloggers, respectively. The average recovery rates were 63% for clay, and 71% for both sand and S&C cloggers on applying the pressure washing technique. However, vacuuming followed by pressure washing shows a maximum recovery rate of 78, 77 and 64% against clay, sand and S&C cloggers, respectively.

Analytical Approaches for Reinforced Concrete
Social media and influencers in the lives of teenagers
Authors: Iwanicka Agnieszka
Published: June 2023

The article aims to look at the growing role of social media, with particular emphasis on the part of influencers in the lives of adolescents. The article is a review based on the empirical research available on this topic. Contact with influencers meets not only the relational, informational, or entertainment needs of young people but also the need to compare ourselves with other people present in our lives. On the other hand, it can maintain the fear of FOMO, which in the long run results in a reduction in the adolescent’s social well-being. The article invokes the theory of social comparisons and discusses the supporting role of parents in the context of Berne’s structural analysis of social media use by adolescents. The transactional analysis also considered the specifics of influencers’ contact with their recipients.
Educational strategies of teachers with differentiated self-realization styles
Authors: Rubacha Krzysztof
Published: June 2023

This article presents the results of a study based on the relationship between teachers’ self realization styles and the educational strategies they employ to stimulate the psychological development of female and male students. Five self-realization styles were measured: self-acceptance, others acceptance, solving social conflicts, solving internal conflicts, non-self-realization and a random variable in the form of the following educational strategies: reinforcement, development, adaptation, and ideology. The results from the random sample demonstrated a general difference between the group of teachers who did not realise their potential (non-self-realization) and the other teachers who presented different self-realization styles. The former group identifies with heterogeneous strategies, whereas the latter identifies with autonomous strategies. This regularity was not the case for reinforcement strategies, whereby all groups employed an individual (autonomous)rather than a collective (heteronomous) reinforcement strategy.

It closely relates the level of effectiveness to the expected performance of each activity. Higher expectations should release energy and affect effective results of education or professional work. The aim of this article is to analyze the sense of effectiveness in life of students who started their studies in science and humanities. For this purpose, I have carried research out based on an own project taken among 383 students of the Rzeszów University of Technology and The University of Rzeszow. The research used a diagnostic survey method, and a standardized tool to measure the level of effectiveness in life using the Generalized Self-Efficency Scale (GSES) developed by Ralf Schwarzer and Matthias Jerusalem and prepared in Polish adaptation by Zygrfyd Juczyński.The research showed that the students’ sense of effectiveness in life was moderate. The following independent variables were taken into account: university, gender, age, place of residence and the wealth of the respondents. In two studies, there was a difference in the level of statistical significance depending on the type of university and the gender of the respondents. On the other hand, taking into account the average, students from the Rzeszów University of Technology showed a slightly higher level of sense of effectiveness in contrast to students from the University of Rzeszów. The conclusions from the research constitute a challenge for the education system, teachers at all levels of education, so that any changes, systematically introduced to the education programs, could reflect the needs of students to a greater extent.

Authors: Moczia Krystyna , Niemiec Marta
Published: June 2023

Caused by the SARS-CoV-2 virus, the COVID-19 pandemic can already be considered one of the more difficult situations that societies had to face over the last two years. This article presents quantitative analysis of the assessment and experience of the pandemic period from the perspective of those adult wards of the Municipal Social Welfare Centres (MOPS, the abbreviation derived from the institution’s Polish name) in Katowice and Częstochowa who run independent households. The text closes with a discussion in which the authors attempt to summarise and interpret research results with regard to the assumptions of Transactional Analysis (TA). What inspired the authors to undertake their own research presented here were the research results obtained as part of a project carried out by a team of scholars established to study the determinants of life and work during the COVID-19 pandemic; the research team was formed at the Institute of Pedagogy, Faculty of Social Sciences, University of Silesia in Katowice, and the authors of the present study were its members. In late 2020 and early 2021, the team conducted research on “Challenges, contexts and determinants in the life and work of MOPS wards and staff during the COVID-19 pandemic”. The findings obtained by the team in the course of their research were presented in two reports titled: Social Welfare During the COVID-19 Pandemic. A Report on Research Conducted in the City of Katowice and Social Welfare During the COVID-19 Pandemic. A Report on Research Conducted in the city of Częstochowa. The present study provides an indepth quantitative insight and further details regarding the aforementioned research results developed within the framework of these reports.
Computer games in the hierarchy of importance of children’ and adolescents’ activities in the ICT world – research report: learners’ and teachers’ opinions
Authors: Baron-Polańczyk Eunika
Published: June 2023

The article presents a fragment of diagnostic-correlative research of a mixed character, identifying learners’ information literacy in the use of ICT methods and tools. The author aims to answer the question defining the frequency of using ICT by children and adolescents (hierarchy of importance of activities) in the area of computer games. For this purpose, the method of a diagnostic survey (questionnaire and interview) and statistical methods (chi-square test of independence and Pearson’s correlation coefficient) were used. Together, 2510 learners and 1110 teachers (in Poland) were involved. It was established that: 1) according to the aggregate hierarchy of importance of activities undertaken in cyberspace, the learners attached little weight (fourth place)when the teachers the greatest (first place) to computer games; 2) there is a relationship (correlation: average, positive – r  0,49) between the learners’ and teachers’ opinions as to the frequency of using ICT instruments by children and adolescents in order to play; 3) the calculations showed significant statistical differences between the frequency of using ICT by children and adolescents in the area of computer games and their gender and the stage of education; 4) there is a noticeable similarity between the opinions of the learners and the teachers and an insignificant „separation” of the world of children and youth (“Us”) from the world of teachers (“Them”).
Healing experiences and psychological effects of travel according to travel motivation
Authors:   The Tourism Sciences Society Of Korea, Hong Min-Jung
Published: June 2023

This study was conducted to examine the relationship between the healing experience and psychological effects of travel based on different motivations, as well as the differences between healing experiences and psychological effects of travel based on travel motivation. Using cluster analysis, ANOVA, and multiple regression analysis on 247 valid samples collected from a survey of Korean travellers, an empirical analysis was conducted. First, after verifying differences in healing experiences and psychological effects between groups of travel motivation types derived from cluster analysis, it was determined that travel motivation is crucial for new experiences, relaxation, and recharging. In addition, travelling to strengthen relationships can be detrimental to an individual's psychological recovery. And, among the factors of travel motivation, new experiences, relaxation and recharging, and historical and cultural exploration had a positive effect on healing experiences, whereas relationship strengthening had a negative effect on cognitive healing experiences. It was discovered that the motivational factor of conspicuous consumption did not affect all healing experiences. Last but not least, it was discovered that emotional and cognitive healing through travel had a positive effect on psychological effect. Based on these results, it can be seen that rest and new experiences must be properly combined to expect an individual's psychological healing effect through travel, suggesting the need for the development of healing tourism products. In the conclusion, academic and practical implications of this research were discussed in greater depth.
Legislative Oversight and Executive Accountability in South Africa
Authors: Maganoe Shadi
Published: June 2023

A glance at political theory reveals a preoccupation with the corrosive nature of power, in particular with how to ensure that the governors are sufficiently accountable to the governed. Legislative oversight is a constitutional requirement in the South African system of government. However, poor performance, maladministration and a lack of accountability in various government institutions have continued to be a major challenge. In recent years the implementation of legislative oversight has proven to be a challenge, with findings of abuse of state power revealed by reports from the Office of the Public Protector as well as corruption scandals in procurement processes. This study examines the role of parliament in holding the executive accountable in line with the constitutional values of transparency, accountability and responsiveness. Apart from delineating the reach of parliament's powers and functions, the main thrust of the study, given the existing vicissitudes in our constitutional edifice, including the failure of parliament to hold the executive accountable, is on how to strengthen the institution of parliament in its oversight role.
Theoretical study of the curvature of the treated surface during oblique milling with prefabricated milling cutters

Published: June 2023

Introduction. The paper discusses the methods of processing large parts having curved convex surfaces with a rectilinear guide on multi-coordinate CNC machining centers using the touch method with a discrete motion of the tool feed along the profile of the part. It is shown that the main disadvantages of this method are lower productivity, which is due to the presence of discrete tool motions between cycles of its translation mode, where the value of discrete tool motion for a given processing accuracy depends on the curvature of the surface being processed. To improve processing performance, it is proposed to use prefabricated disc cutters equipped with replaceable polyhedral inserts (RPI) with rectilinear cutting edges. Its installation in the cutter body with non-zero angles of inclination of the main cutting edge, in combination with an additional rotation of the cutter, during processing, along the direction of the translational feed movement, allows you to obtain a concave surface and ensure a tighter fit of the producing surface of the tool and the machined surface of the part. The aim of the work is to reduce the error of approximation of the profile when it is processed using the touch method with discrete motion of prefabricated disc cutters along the profile and, consequently, to ensure workpiece the possibility of increasing the step of tool movement along the profile being formed to improve processing performance. Research methods: geometrical theory of designing metal-cutting tools. Results and discussion. The regularities established in the work made it possible to create a method for determining the angle of inclination of the main cutting edge of the RPI milling cutter and the angles of rotation of the milling cutter along the direction of translational feed movement during line-by-line processing of extended sections of parts with a curved profile on multi-coordinate CNC machines by turning the milling cutter to ensure the best fit of its producing surface to the surface being processed at the point of its contact, to reduce the approximation error processed profile and improve processing performance, due to the possibility of increasing the tool movement step.
