As Nigeria continues to expand its industrial, commercial, and residential cooling needs, the demand for efficient and environmentally sustainable refrigeration systems is growing. However, the environmental impact of conventional refrigerants has raised concerns due to their high global warming potential and ozone depletion potential. This study presents a thermodynamic analysis of two-stage vapour compression refrigeration systems in Nigeria, utilizing eco-friendly refrigerants which offer low global warming potential and zero ozone depletion potential. The refrigeration system comprises a high-pressure stage compressor and a low-pressure stage compressor with the inter stage pressure taken to be the ideal inter stage pressure. Performance analysis of R-717, R-600, R-600a and R-290 two-stage vapour compression refrigeration systems were made using seven parameters. The effect of the variation of five operating/design parameters (evaporating temperature, condensing temperature, superheating temperature, sub cooling temperature and refrigerant mass flow rate) on Coefficient of Performance (COP) of two-stage vapour compression system was analysed using engineering equation solver software. The results showed that as evaporating temperature decreases from 0oC to -50oC, COP decreased for all the four refrigerants considered. R-717 gave the highest COP value of 7.636 at evaporating temperature of 0oC while R-600a gave the lowest value of 4.009 at the same temperature. The results also showed that the COP of all the four refrigerants increased with increase in sub cooling temperature and Superheating Temperature, whereas it decreased with increase in condensing temperature. The study revealed that, except for the mass flow rate, all other operating parameters significantly affect the COP of refrigeration systems considered.

Authors: Wang Chen
Published: January 2025

The steel pipe column-Berger beam support system is widely utilized in bridge construction due to its simple structure, convenient installation, high load-bearing capacity, and excellent stability. Stability research on this system is therefore essential. This study employs ANSYS finite element software to conduct a comprehensive analysis, including buckling behavior, node stiffness, and initial defects in the Berger beam support system. The research identifies the first four buckling modes, examines load-displacement curves corresponding to node stiffness values ranging from 0 to 400 kN·m/rad, and evaluates load-displacement curves under varying initial defect ratios. These findings contribute to improving the design and application of the support system. This study not only addresses gaps in current research but also serves as a valuable reference for scholars in related fields. Additionally, it provides practical guidance for engineers involved in bracket design, significantly enhancing their efficiency and effectiveness. In conclusion, the research presented in this paper holds considerable importance for both academic and practical advancements in the field.

Authors: Chianebeng Japhet Kuma , Ngong Diom Jacob , Doumtso Marcel
Published: January 2025

Market spaces are fundamental to urban life in Cameroon, serving as key centers for commerce, social interaction, and cultural exchange. However, rapid urbanization has intensified challenges related to the spatial placement and organization of markets, particularly in Bamenda. Poor infrastructure, congestion, spatial disorganization, and inadequate parking facilities hinder accessibility and affect the efficiency of market operations. These challenges not only limit economic activities but also create difficulties for vendors, customers, and other stakeholders who rely on these markets for daily sustenance and business. The research problem centers on the inefficient spatial arrangement and poor management of market spaces in Bamenda, which contribute to accessibility constraints, safety concerns, and overall dissatisfaction among market participants. This study, therefore, aims to examine the spatial location, layout, and design of major markets in Bamenda, including Bamenda Main Market, Nkwen Market, Food Market, and Ntarikon Market. It seeks to analyze how these spatial characteristics impact accessibility and functionality, as well as to identify the major challenges faced by market participants. To achieve these objectives, the study employs both qualitative and quantitative methods, including informant interviews and the administration of 324 questionnaires to vendors, customers, and shop owners. Spatial analysis mapping is utilized to assess market locations, layouts, and proximities, providing a comprehensive understanding of their spatial organization. The findings indicate that congestion, narrow pathways, inadequate infrastructure, and unregulated market expansion significantly impede accessibility and market efficiency. Given these challenges, the study strongly advocates for the effective implementation of Bamenda’s proposed Master Plan to regulate urban spaces, particularly market infrastructure. Additionally, the proper execution of the Plan of Soil Occupation (POS) is recommended to address the haphazard arrangement of market stalls and control illegal market operations.

Published: July 2023

Insect-borne viral diseases epidemics are influenced by interaction among host plants, viruses, their vectors, and environment. Two species of mealybugs i.e. Planococcus minor and Ferrisia virgata are known as virus vectors that cause mottle disease on black pepper (Piper nigrum). Research was conducted to determine the main factors affecting mottle disease spread in the field. Study was conducted by observing 30 productive black pepper plants at the experimental field in Sukabumi, West Java. The parameters involved abundance of mealybugs, severity of mottle disease, and yield of black pepper plants. Disease severity and plant yield was assessed for three consecutive harvest seasons, while mealybug abundance was observed every two months for a year. The results showed that abundance of mealybugs did not have significant affect to disease severity and plant yield, indicating the vectors in the field does not play as a prominent role in disease spreading. Simple linear regression between disease severity and plant yield showed coefficient determination of R2 value about 0.4351 with negative correlation, indicating opposite effect between severity and plant yield. Increasing disease severity affect moderately plant yield decrease. Therefore, planting virus free seed stocks and applying good cultivation practices in the field will inhibit disease development and spreading which in turn will affect continuous optimal plant yields.

Esta investigación tuvo como objetivo caracterizar el conocimiento de los maestros en formación inicial de matemáticas acerca de los Objetos Virtuales de Aprendizaje. Para esto, mediante un enfoque cualitativo y una metodología en fases se realizaron grupos focales y una entrevista con un cuestionario de 15 preguntas semiestructuradas, subdivididas en 5 categorías relacionadas con la investigación: (i) Conocimiento sobre la importancia de la utilización de las TIC, (ii) Utilización y frecuencia de las TIC en el aula, (iii) Formación acerca de las TIC en los maestros de matemáticas en formación, (iv) Formación acerca de los OVA en los maestros de matemáticas en formación y conocimiento sobre su importancia en el aula, (v) Fortalezas y debilidades en la implementación de los OVA, la cual fue validada por el método Delphi. Se encontró como principal hallazgo que la mayoría de los participantes se identifican con la postura de que el uso de los OVA es necesario para la enseñanza de las matemáticas de manera efectiva, dado la interactividad que conlleva su utilización en dicho proceso. No obstante, carecen de conocimientos tecnológicos debido a su escasa formación en las asignaturas relacionadas con las TIC en Educación Matemática. Se concluye que los maestros en formación inicial no relacionan a los OVA con sus conocimientos tecnológicos y pedagógicos para la enseñanza de las matemáticas, dado que, en su mayoría, señalaron las ventajas que ofrecen dicha herramientas en el contexto educativo, pero en sus prácticas pedagógicas solamente las visualizan como presentaciones de power point.

Doctors Duty of Informed Consent and Patient Informed Consent Form
Authors: YU Ho-Jong
Published: July 2023

1. When a patient goes to a hospital, he is expected to give consent to the treatment his/her doctor may provide. The initial consent, however, does not include all the consents to the following treatment a patient is going to receive. For further treatments, especially for concrete treatments, the doctor must seek for additional consents.
2. A doctor must offer sufficient informations to his patient when getting a consent. While doing this a pre-written patient informed consent form can be convenient as well as effective. The doctor can explain systematically without leaving out any important point, and the patient can understand much better what the doctor is explaining by reading the paper repeatedly. Furthermore this same form can be useful later on when any legitimate question arise.
3. I reviewed many patient informed consent forms previously made by many academies of medical science in specific medical fields. I find the papers lacking in sufficient informations especially on alternative treatment measures. Even if there are, they are described negatively, which make the forms suspicious of giving biased informations. Above all the terms used are too difficult for the patients to understand. I, therefore, propose a patient informed consent form, which I believe might be ideal.
The Nuremberg Code and Ethics of Human Subject Research
Authors: KIM Ock-Joo
Published: July 2023

Nowadays human subject researches encompass various kinds of biomedical researches: clinical trials, population studies, epidemiological studies, genetic studies, reproductive studies, stored sample studies, etc. While each category has its own specific ethical issues and corresponding guidelines, universal guidelines of human subject research have been developed at the international level. The Nuremberg Code adopted in 1947 marked a major turning point in the history of research ethics. Although risks related to human subject research has been known since ancient time, the Nuremberg Code initiated international efforts to protect human rights in biomedical researches. For 2500 years, the Hippocratic Oath has stressed the physicians integrity and loyalty to the patient. The Nuremberg Code shifted the main point of medical ethics from physicians attitude to the voluntary informed consent of research participants. As reflected in the Code, the traditional doctor-patient relationship (the healer-patient relation) extended to include the researcher-subject relation in modern times.
The Nuremberg Code came out from the painful chapters of the history of human experimentation during the World War II. At the Nuremberg Trial in 1946-47, twenty three Nazi scientists and doctors were prosecuted for their inhuman human experimentation. While the trial revealed Nazi physicians' cruelty, the judges tried to establish international consensus concerning what is an acceptable experiment on human being throughout the trial. Fifteen defendants were sentenced as guilty of crime against humanity and war crime. The Nuremberg Code was proclaimed as a part of final verdict of the trial.
In this paper I examine in what historical context the Code was shaped; what are lessons of the Nuremberg Trials; and what is the legacy of the Code. Although the Code initiated the international efforts to establish ethic of human subject research, the Nuremberg Code and following Declaration of Helsinki has never guaranteed protection of the human subjects of biomedical researches.
Ethics Education in Korean Medical Schools
Authors: Meng Kwang-ho
Published: July 2023

Ever since two Christian medical schools, one Catholic and one protestant began teaching medical ethics to the students as a regular teaching subject in early 1980s, number of medical schools adopting the medical ethics course has been steadily increased as the importance of teaching medical ethics in medical schools has been stressed in various literatures.
However, few data exist describing current practices in medical ethics education in Korea.
This study aimed to find out how many medical schools are including ethics education in their curricula and analyze the pattern of ethics education by the type of school, years founded and the class size of the medical schools.
Major findings obtained from this study are as follows:
1. All 41 medical schools in Korea were providing ethics course; as a regular course subject in 37 medical schools and as an integrated/special lectures in the rest 4 medical schools.
2. Thirty three medical schools(80.5%) reported teaching ethics in one year only and the rest 8 medical schools reported teaching ethics in more than 2 years. Two medical schools were providing the courses in 5 years.
Sixteen medical schools(39.0%) reported providing the courses in the third year of medical course and 12 medical schools(29.3%), in the second year of medical course or in the second year of pre-medical course.
3. Mean number of hours for ethics teaching in 41 medical schools was 29.7±24.1 (range: 5-136), and the mean number of credits was 1.6±1.4 (range: 0-8).
4. Most common content areas taught in Korean medical schools were 'ethical concept'(in 39 medical schools), 'reproductive ethics' and (in 37 medical schools), and 'ethical principles', 'dr-patient relationship', and 'death and dying ethics' (in 36 medical schools).
Twenty four medical schools(58.5%) were using course materials developed by the schools themselves or faculties, but 19 medical schools(46.3%) were using the textbook developed based on students learning objectives and published by the Korean Society for Medical Ethics Education. Eleven medical schools(26.8%) were combining other textbooks on medical ethics

Published: July 2023

Fuel is one of the tools to drive the machining system that moves from the fuel tank to the engine. Although there are several areas that have switched to using electric vehicles, vehicles that use fuel oil still dominate the public in various countries. The purpose of this research is to identify the causes of a dirty fuel filter in an auto repair shop. The methods used in this analysis are Failure Mode and Effect Analysis (FMEA) and fishbone diagram analysis. Based on the results and discussion, the cause of the dirty fuel filter is the causal factor from the method side, namely due to negligence in maintenance, from the material side because the fuel tank is dirty and the fuel is not good, from the engine side because of continuous use without maintenance, from the human side because it is not routine maintenance, due to carelessness in maintenance, and due to frequent changes in the type of fuel.

Published: July 2023

Le sous-équipement, la destruction rapide du cadre de vie, l’inaccessibilité aux services de base et les vulnérabilités sont les problèmes environnementaux rencontrés dans les quartiers BATUMONA à Kimbanseke et TALANGAY à N’sele dans partie-Est de la ville de Kinshasa et méritent des solutions appropriées, pour espérer aux lendemains durables dans l’aire d’étude. Les mauvaises conditions d’approvisionnement en eau potable, électricité et assainissement dans les sites étudiés sont à la base de dysfonctionnement actuel dans les sites étudiés et risque de provoquer plus tard leurs isolements.                   Par ailleurs, l’étude précise que le phénomène de vulnérabilité est très peu connu sur le plan scientifique et trop peu pris en compte par les décideurs et autres acteurs des dynamiques urbaines sur le continent africain en général et en particulier en République Démocratique du Congo GUIGMA & ali.,(2015), MPIANA TSHITENGE, (2015) & KABUYAYA,(2015). Les études réalisées par plusieurs auteurs précisent que posséder une connaissance relative au phénomène des vulnérabilités environnementales exigent de s’intéresser tant aux causes qu’aux conséquences de ce phénomène.               Ce phénomène résulte d’une problématique complémentaire qui se rapporte aux effets socio-économiques et environnementaux de la production de l’urbanisation et de la périurbanisation. Il s’agit là de la problématique émergente de l’efficacité urbaine, qui n’est d’autre que la manière dont l’organisation de l’espace urbain produit des effets souhaités sur le triple volet social, économique et environnemental MESSINA, (2018). En rapport avec les résultats de l’étude, l’on peut considérer que dans la perception du concept de vulnérabilité environnementale, les conditions environnementales immédiates des sujets enquêtés ont beaucoup joué dans le contenu formulé sous le concept. Les précarités urbaines et plusieurs manifestations de catastrophes et risques environnementaux auxquels sont confrontés plusieurs enquêtés ont élevé les scores de deux principales assertions, à savoir : difficulté d’accès aux services de base et conditions de vie déplorables ainsi que l’exposition aux catastrophes naturelles. Les autres scores, non négligeables sont accidentels et dépendent de plusieurs contextes familiaux rencontrés par les ménages enquêtés.

Analysis of Diffuse Large B-cell Lymphoma using Immunohistochemical Algorithm: A Cross-sectional Study
Authors: Scaria Jasmin , Rani ER Jyothi , Sathi PP
Published: July 2023

Introduction: Diffuse Large B-cell Lymphoma (DLBCL) is the most common Non-Hodgkin’s Lymphoma (NHL). Using Gene Expression Profiling (GEP) DLBCL has been subtyped into two groups of prognostic importance, Germinal Center B-cell (GCB) like and activated B-cell like. GCB DLBCL has a better survival and can be identified using Hans algorithm with three immunohistochemical markers Cluster Differentiation (CD10), B-cell lymphoma 6 (BCL6) and Multiple Myeloma Oncogene-1 (MUM1). Aim: To analyse DLBCL using Hans algorithm as both GCB lymphoma and non GCB lymphoma have different treatment and prognosis. Materials and Methods: This was a cross-sectional study conducted in the Department of Pathology, Government Medical College, Kozhikode, Kerala, India, from January 2019 to December 2020. A total of 97 DLBCL cases received in the Department of Pathology, from January 2016 to December 2019 were included in the study were subtyped using Hans algorithm. CD10, BCL6 and MUM1 were considered positive, if more than 30% of the tumour cells showed staining by the respective antibodies. The relation between DLBCL subtypes and the age, gender, symptoms, site of initial involvement, organomegaly, Ann Arbor stage, treatment response and overall survival. Findings in the patients were analysed using Chi-square test. Statistical Package for Social Sciences (SPSS) software version 18.0. Overall survival was estimated using Kaplan-Meier method. Results: The median age of study population was 60 years (age range: 31-85 years) and there were 55 (56.7%) males and 42 (43.3%) females. Out of the 97 DLBCL cases 47 (48.5%) were GCB and 50 (51.5%) were non GCB subtype. Statistical analysis was done only in 88 patients (excluded nine recurrent lymphoma patients, which may have a different outcome). There was significant association (p-value=0.003) between stage and subtypes as majority of the non GCB cases presented in an advanced stage. The rate of complete remission with Rituximab Cyclophosphamid Hydroxydaunorubicin Oncovin Prednisone (RCHOP) chemotherapy was higher in GCB (58.75%) compared to non GCB (15.25%) subtypes (p-value=0.001). Overall survival rate of GCB was 74.4% and non GCB was 31% with a p-value of 0.001. There was no statistically significant relation between DLBCL subtypes and other clinicopathological factors. Conclusion: In the present study, the patients within the GCB subtype had better treatment response and overall survival rate compared to non GCB subtype. Non germinal center subtype presented in advanced stage and had a worse prognosis. Therefore, it is essential to subtype DLBCL in all cases to identify non GCB subtype, which may need additional treatment after RCHOP chemotherapy.
A systematic literature review: Setting a basis for smart and sustainable city performance measurement
Authors: Karal Fatma Sena , Soyer Ayberk
Published: July 2023

The growing amount of data and the inventive solutions that arise from it create opportunities to construct and manage smart sustainable cities. Before attempting to establish appropriate solutions in this regard, it is crucial to clearly grasp what smart and sustainable cities are and the aspects around which they are built. The purpose of this study is to critically analyze and evaluate the studies that have been conducted on smart and/or sustainable cities and to provide a basis for the measurement of smartness and sustainability of cities. In this context, using Systematic Literature Review (SLR) methodology, the smart city, sustainable city, and smart sustainable city concepts are firstly defined. After that, the indicators for the assessment of the smartness and sustainability of cities and the selection processes of these indicators are analyzed. According to the analysis, the studies were grouped based on the use of (i) selection criteria, (ii) selection methods/tools, and (iii) models used and 14 criteria were deduced from the literature for the evaluation of performance assessment indicators: measurability, availability, completeness, relevance, independence, reliability, currency, responsiveness, simplicity, representativeness, cost‐effectiveness, consistency, comparability, and consensus. This study aims to support other studies and applications of authorities on creating and assessing a smart and sustainable city (i.e., the indicators) that want to join the 2030 Agenda but face problems regarding their cities' specific conditions. The first step towards creating a smart sustainable city can be taken by determining the most suitable indicators for the city.
Enhanced Tidal Sensitivity of Seismicity Before the 2019 Magnitude 7.1 Ridgecrest, California Earthquake

Earth's crust is continuously subjected to oscillatory stress perturbations due to the solid Earth and ocean tides. The seismic response to such stress modulations carries information on earthquake physics and crustal properties. Experimental and observational studies suggested but could not demonstrate that the strength of tidal modulation of seismicity increases before large earthquakes. We tested this hypothesis by (a) developing a new, comprehensive 10‐year long earthquake catalog preceding the 6 July 2019 magnitude 7.1 Ridgecrest, CA earthquake, and (b) applied our novel method for extracting a statistical signal of tidal modulation. Our results show enhanced tidal sensitivity of seismicity along the fault starting about 1.5 years before the mainshock, corroborating the hypothesis. This observation suggests that small magnitude earthquakes may be used to gain insight into subtle changes in fault conditions, bringing new promise for studying the earthquake preparation process.

Consumer wearable technology use is widespread and there is a need to validate measures obtained in uncontrolled settings. Because no standard exists for the treatment of heart rate data during exercise, the effect of different approaches on reliability (Coefficient of Variation [CV], Intraclass Correlation Coefficient [ICC]) and validity (Mean Absolute Percent Error [MAPE], Lin’s Concordance Correlation Coefficient [CCC)] were determined in the Polar Verity Sense and OH1 during trail running. The Verity Sense met the reliability (CV < 5%, ICC > 0.7) and validity thresholds (MAPE < 5%, CCC > 0.9) in all cases. The OH1 met reliability thresholds in all cases except entire session average (ICC = 0.57). The OH1 met the validity MAPE threshold in all cases (3.3–4.1%), but not CCC (0.6–0.86). Despite various heart rate data processing methods, the approach may not affect reliability and validity interpretation provided adequate data points are obtained. It is also possible that a large volume of data will artificially inflate metrics.
Rascal Concepts
Authors: Peck Jamie
Published: July 2023

This chapter takes the form of a critical evaluation of the “rascal concept” of neoliberalism, commenting on its uneven reception and take-up across the critical social sciences and on the particular contributions of economic geography and urban studies. “Neoliberalism,” it is argued, can only exist in hybrid, mixed forms, never coming close to purity or for that matter approaching completion. These ontological facts mean that essentialized and singular conceptions of neoliberalism are unhelpful, if not actively misleading, and that the phenomenon can only exist in “multi-conjunctural” form. And this also means that considerations of spatiality, “local” particularity, and uneven geographical development are in no sense secondary, but in fact represent fundamental issues in the definition, analysis, and exploration of ongoing processes of neoliberalization.
Dickens, Death, and Christmas
Authors: Patten Robert L.
Published: July 2023

“Marley was dead, to begin with.” Why does the most beloved of Christmas books open with a death? What has death to do with Christmas and New Year’s, and with Dickens’s Christmas books and stories over his entire life? Patten starts at the Paris Morgue and takes Dickens through his Christmas experiences from childhood on, his celebrations of the season and the sorrows that he often reviews in the New Year. Patten weaves together Dickens’s life, career, writings, journalism, travel, theatrical presentations, and religious convictions—he was composing his Life of Our Lord for his children simultaneously with his Christmas books. This is a richly designed and entertaining narrative, fulsomely illustrated, of the manifold ways Dickens figures the spirit and traditions of the winter holidays in Victorian England. Both the gothic of ghosts and retribution and the grotesque of lower-class enjoyment surface importantly in Dickens’s fantasies. Patten writes for a general audience, bringing various encompassing theories about time and narrative to bear in easily understood ways. He discloses many hitherto overlooked connections between Dickens’s writings and life. And he arrives at some surprising conclusions about Dickens’s imagination, understanding of the conditions and meaning of Christian life, and the failures of British society to meet the pressing needs of its people. Not only does he address the public reception of these writings; he also tracks the responses and understandings of Dickens’s illustrators, friends who found novel ways of telling, and mistelling, the stories.
Marley Was Dead
Authors: Patten Robert L.
Published: July 2023

A Christmas Carol deals with time, past, present, and future, and how it enables stories, even from beyond the grave. Using Frank Kermode’s terms “chronos” and “kairos” in The Sense of an Ending, the chapter delves into successive and repetitive times, Advent imagery, the possibilities of reformation and rebirth, ghosts and purgatory, alternate futures in which Scrooge and Tiny Tim both die at Christmas, business and charity, seasonal celebrations and games, gifts, and the teachings of Christ and how they have been traduced. The real and fictional deaths of children in December that Dickens knew are reinforced by the deaths of Scrooge and Tiny Tim. Dickens’s strategies for storytelling follow precepts articulated by Walter Benjamin, antithetical to the aesthetics of Henry James. The reading concludes by disagreeing with a classic dismissal of Scrooge’s conversion, by Edmund Wilson; it instead gathers the ways narrative and illustrations instantiate that change of heart.
Innovation as an Evolutionary Process
Authors: Dosi Giovanni
Published: July 2023

The chapter ‘zooms in’ on the analysis of sources, procedures, and microeconomic effects of innovation. It starts from the basics—that is, what is technology—in terms of problem-solving knowledge, procedures, recipes, routines, and ensuing artefacts. Next, it explores the structure and dynamics of such knowledge in terms of technological paradigms and the implications in terms of trajectories of technological change. There are a few features which the generality of paradigms have in common and others that differentiate them in terms of richness of opportunities of innovation and their sources, tacitness of the underlying knowledge bases, cumulativeness in the processes of innovative advances, and appropriability of the economic benefits from the innovation itself. Different paradigms map into different sectoral regimes of innovation and industrial dynamics, from which one can build illuminating taxonomies. The economic impact of innovations depends on their diffusion. Thus, it is crucial to understand whether they diffuse at all and the determinants of the rates and patterns of diffusion themselves.
The Structure and Evolution of Industries
Authors: Dosi Giovanni
Published: July 2023

Differences in products and in processes of production—and, as a consequence, costs and prices—are central features of the competitive process by which heterogeneous firms get selected, with some firms growing, some declining, some going out of business, and some new ones always entering on the belief that they can be successful in this competition. Such processes of competition and selection are continuously fuelled by the activities of innovation, adaptation, and imitation by incumbent firms and by entrants. The competitive process involves selection across firms. But underlying that rests learning on techniques, organizational practices, and product attributes within the firms themselves. Ultimately, learning and competitive selection are the two central drivers of changing industry structures and industrial demographics. We begin with the evidence concerning some general features of (a) firms’ characteristics and industrial structures and dynamics, broadly understood to cover variables such as size, productivity, innovativeness, age, and their intra-industry distributions; and (b) performances—including individual profitabilities, growth profiles, market turbulence, and survival probabilities, together, again, with their aggregate distributions. Next, we present different families of models apt to account for the foregoing ‘stylized facts’ as emergent properties of industrial evolution.
