Published: May 2023

Introduction: Stress is the body's response to threatening external stimuli. Many medical students experience stress. Stress that medical students share can be caused by learning demands, interpersonal problems, and other things. Even though stress is daily, excessive stress can also cause various health problems, including headaches. Headache is the most common neurological problem in the world. There are several types of headaches, one of which is tension headaches. However, the relationship between stress and headaches, especially tension-type headaches in medical students, has yet to be widely studied.
Methods: This study is a cross-sectional analytic observational study, on 120 pre-clinical students (22 males, 98 females) aged 18-21 from the School of Medicine and Health Sciences, Atma Jaya Catholic University in Jakarta. The questionnaire used to measure the respondent's stress levels were the Depression Anxiety Stress Scale 42 (DASS-42) and Headache Screening Questionnaire (HSQ) to determine the respondent's headache. The data obtained were analyzed statistically using the Chi-square method, with a p-value <0.05.
Results: Out of 120 students, 74.2% experienced stress within normal limits, while 9.2%, 10%, 5%, and 1.7% reported experiencing mild, moderate, severe, and very severe stress levels, respectively. 30.8% of students experienced tension-type headaches, and 69.2% of students did not. The result obtained from the chi-square bivariate test was p = 0.188.

The Challenge of “Doing Business with Strangers”: Audit Reports as a “Signaling Instrument
Authors: DALOĞLU Pınar , BALIKCI Emre
Published: May 2023

This paper discusses how firms in Turkey have used audit reports of companies like Deloitte as a "costly signaling" instrument. The paper shows that the firms integrating into the global economy during 1990s were in intense competition to find global business partners. The need to do "business with strangers" created a new challenge for this firms: Broadcasting strong signals proving the capacity of being a reliable, long-standing business partner. When the partnerships were formed in smaller business circles, these signals were produced by face-to-face social interactions. But when the entrepreneurs cooperate/negotiate with firms from different national and cultural backgrounds, audit reports from prestigious companies became a universal signal about the firms' reliability. To illustrate the transformation in this "signaling" process, we conduct in-depth interviews with the managers of auditing firms, entrepreneurs and did an archival study on many resources of the period.

Published: May 2023

Microbial fuel cells (MFCs) rely on the capacity of electrode-adhered electroactive bacteria to oxidize organic matter and generate electrons. Typical MFCs are highly engineered systems that can be applied as green tools to alleviate the burden of waste streams. Phototrophic MFCs (PhMFCs) are a promising variant that can be implemented indoors or outdoors and use the power of the sun to boost efforts in on-site environmental remediation, biomass generation, and power generation. PhMFC variations include plant-based and algal-based MFCs. Algal-based MFCs can incorporate special photosynthetic action at either the anode or cathode, enhancing or replacing the role of other bacteria in regular bacterial MFCs. Plant-based MFCs can be more complex due to the role of the root system near an electrode and its interaction with electrode-adhered bacteria, and they are nearly universally operated outdoors in either natural or engineered conditions. This review considers PhMFCs such as algal-based MFCs, algal carbon capture cells (ACCCs) and anode algal microbial fuel cells (AAMFCs), and also plant-based MFCs which include natural plant MFCs (NPMFCs), constructed wetland MFCs (CWMFCs), and marine-rooted plant MFCs (MPMFCs). After summaries of the fabrication and function of different PhMFCs, we elaborate with a literature review and discussion on each variant, followed by suggestions for future directions that will enhance the impact and accelerate the uptake of these promising multi-functional biosystems.
Interfacial Water Flipping and Electrostatic Fields at the Electrode:Electrolyte Interface from operando Nonlinear Optical Spectroscopy
Authors: Geiger Franz , Speelman Raiden
Published: May 2023

Water's oxygen is the electron source in the industrially important oxygen evolution reaction, but how water interacts with an electrode's active sites remains poorly understood. Much microscopic insight into the Stern layer water structure and the interfacial fields currently comes from atomistic simulations,1-6 with joint theoretical and surface-specific experimental studies just emerging.7-9 The strong absorber problem for water in particular has hampered our molecular understanding of how the water molecules in the Stern layer orient themselves in response to an externally applied potential. Here, we employ operando nonlinear optics with a non-resonant pulse triplet while recording cyclic voltammograms at Ni:NiOx electrodes in contact with pH 13 electrolyte. We quantify the number of net-aligned Stern layer water molecules that point their oxygen atoms towards the electrode in response to the externally applied potential and obtain the total electrostatic field across the electrical double layer by quantifying the total potential. We find that the energy associated with water flipping is parabolic in the fraction of Stern layer water molecules flipped and comparable to the cohesive energy of water and ice, depending on the choice of the Stern layer relative permittivity (2 and 1.33, respectively).
The protein matrix of plastocyanin supports long-distance charge transport with photosystem I and the copper ion regulates its spatial span and conductance
Authors: López-Ortiz Manuel , A. Zamora Ricardo , I. Giannotti Marina , Gorostiza Langa Pau
Published: May 2023

Charge exchange is the fundamental process that sustains cellular respiration and photosynthesis by shuttling electrons in a cascade of electron transfer (ET) steps between redox cofactors. While intraprotein charge exchange is well characterized in protein complexes bearing multiple redox sites, interprotein processes are less understood due to the lack of suitable experimental approaches and the dynamic nature of the interactions. Proteins constrained between electrodes are known to support electron transport (ETp) through the protein matrix even without redox cofactors, as the charges housed by redox sites in ET are furnished by the electrodes in ETp configuration. However, it is unknown whether protein ETp mechanisms apply to the interprotein medium that is present in physiological conditions. Here, we study interprotein charge exchange between plant photosystem I (PSI) and its soluble redox partner plastocyanin (Pc) and address the role of the Pc copper center. Using electrochemical scanning tunnelling spectroscopy (ECSTS) current-distance and blinking measurements we respectively quantify the spatial span of charge exchange between individual Pc/PSI pairs and ETp through transient Pc/PSI complexes. Pc devoid of the redox center (Pcapo) can exchange charge with PSI and it does so at longer distances than with the copper ion (Pcholo). Conductance bursts associated to Pcapo/PSI complex formation are higher than in Pcholo/PSI. Thus, copper ions are not required for long distance ETp between PSI and Pc but regulate its spatial span and conductance. Our results suggest that the redox center that carries the charge in Pc is not necessary to exchange it in interprotein ET through the aqueous solution, and question the canonical view of tight complex binding between redox protein partners.
Interplay of Intermolecular and Intramolecular Vibrations Mediates Ultrafast Singlet Fission
Authors: Cui Binjie , Jha Ajay , Duan Hong-Guang
Published: May 2023

Singlet fission (SF) is an exciton multiplication process that splits a singlet exciton in organic semiconductors into two triplet excitons and thus, can overcome the Shockley-Queisser limit to improve the solar energy conversion efficiency in photovoltaics. In this paper, we construct a unified model for the ultrafast primary step of the SF process. To achieve that we investigate the dynamics of vibrational modes and their interactions to the relevant electronic excited states in prototypical SF materials, pentacene (exothermic SF) and tetracene (endothermic SF) single crystals. Additionally, the functional role of charge transfer (CT) state is also examined. Using the refined parameters obtained from the reported experimental results, we conclude that the intermolecular vibrations mediate the SF in pentacene with the assistance from strong vibronic couplings to intramolecular modes, which drives the SF process to occur within 100 fs. In this timescale, the CT state has a limiting role towards the SF process in pentacene. However, the CT state plays an important role in a relatively slower SF process of tetracene. Our results disentangle the role of underlying vibrational coherences and clarify the importance of the CT state in tetracene crystal. Hence, with our unified model, we can study the coherent dynamics of SF process, which can principally be extended to the other SF materials as well.

Friction and wear are two major factors affecting the disk brake service life. Carbon-carbon composite materials have good stable friction properties, which enable them to operate as friction material in aircraft brakes application. This article discusses a wear simulation method for predicting the wear amount of c/c composite aircraft brakes under simulated operating conditions. A modified version of Archard’s wear equation is used in 2-D axisymmetric finite element model in order to predict the disk brake friction surfaces wear progression. The finite element commercial software COMSOL Multiphysics 5.5 is used to simulate wear and is presented in this paper. Wear law was implemented as a boundary ordinary differential equation (ODE) in a COMSOL Multiphysics simulation, considering wear depth (thickness) as the independent variable. Frictional heat generation is simulated as heat affects on material thermal properties and as a result surface deformation. Element removal technique is used to simulate the brake disk geometry thickness change due to the material loss during wear. Wear progression with time is presented. Wear model is verified using experimental work from literature.

The data are quantitatively analyzed to determine the support system level from three aspects, namely teaching and learning support, external task support and development of teaching professionalism support. The results showed that the level of support system was high. In particular, new teachers received excellent support from teaching and learning aspects, as well as external duty in implementing NTDP. Meanwhile, the support given by the school for development of teaching professionalism was at a high level. In addition, the study found that there was no significant difference in the support system for new teachers following NTDP based on school level. Support systems needed to be strengthened to help new teachers adapt to the teaching profession, enhancing their potential in carrying out their duties and developing their continuous professional competency throughout their service.
Understanding Energy Conservation in Laos: An Examination of Psychological and Socio-Demographic Determinants of Households’ Intentions to Adopt Energy Conservation Behaviour
Authors:   , Phomsoupha Diane
Published: May 2023

Over the past decades, Laos has experienced an increase in household energy consumption due to population growth and economic expansion. As the country continues to develop, the demand for energy is expected to grow, presenting a significant challenge for Laos in achieving its target of carbon neutrality by 2050. To achieve a transition towards a low-carbon future, increasing the uptake of energy efficiency and conservation in the home is considered to be a key strategy. However, there is a lack of in-depth research on the factors that motivate households in Laos to engage in energy conservation behaviour. Understanding the key determinants of people’s willingness to engage in energy-saving behaviour is vital in informing future policy interventions that aim to encourage households to reduce their energy use.

People’s willingness to engage in household energy-saving behaviours can be associated with many factors. Using the Value-Belief-Norm theory (Stern, 2000) as a theoretical framework, this study examined two broad factors that have been recognised in the literature as important in explaining energy conservation behaviour: socio-demographic (such as age, gender, level of education and household characteristics) and psychological factors (such as values, environmental beliefs, and personal norms). The study further explored the role of these factors in predicting the willingness for households to adopt energy conservation behaviour. A sample of 304 residents in Laos took part in a survey. The results of the quantitative analysis indicated that psychological factors, especially personal norms, awareness of consequences and self-transcendence values, play a significant role in predicting people’s willingness to engage in energy-saving behaviour. While a correlation between socio-demographic factors and the willingness to adopt energy-saving behaviour was observed, these factors were not found to be significant in predicting behavioural intentions when the other variables were controlled for in a regression analysis. The findings of this study then, provide useful insights for policy development, particularly in the design of interventions to promote behaviour change related to energy efficiency and conservation.

In this systematic review study, it is aimed to summarize the findings and reach a conclusion about the role and importance of learning styles in science education at university level from 2007 to 2023. This paper analyzed the studies related to the learning styles in science education at university level. The original studies were extracted from Scopus database, and the review of the 21 selected journal articles revealed that the common feature of the studies in both groups was that learning styles in science education had a positive effect on both cognitive and affective factors. The relation between learning styles in science education at university level and some cognitive or affective factors was investigated. While some studies have found significant differences between these two variables, some studies have concluded that there is no significant relationship. According to the detailed analysis of each 21 articles, the content of the studies was coded as name of the author and year, profile of the participants, research type and major findings. The reviewed research has numerous implications for learning styles in science education at university level.
Enhancing STEM learning with ChatGPT and Bing Chat as objects to think with: A case study
Authors: Vasconcelos Marco Antonio Rodrigues , dos Santos Renato P.
Published: May 2023

This study investigates the potential of ChatGPT and Bing Chat, advanced conversational AIs, as “objects-to-think-with,” resources that foster reflective and critical thinking, and concept comprehension in enhancing STEM education, using a constructionist theoretical framework. A single-case study methodology was used to analyze extensive interaction logs between students and both AI systems in simulated STEM learning experiences. The results highlight the ability of ChatGPT and Bing Chat to help learners develop reflective and critical thinking, creativity, problem-solving skills, and concept comprehension. However, integrating AIs with collaborative learning and other educational activities is crucial, as is addressing potential limitations like concerns about AI information accuracy and reliability of the AIs’ information and diminished human interaction. The study concludes that ChatGPT and Bing Chat as objects-to-think-with offer promising avenues to revolutionize STEM education through a constructionist lens, fostering engagement in inclusive and accessible learning environments.
Klasifikasi Jenis Buah Jambu Biji Menggunakan Algoritma Principal Component Analysis dan K-Nearest Neighbor

The maturity level of guava fruit can be determined by looking at various factors. Shape is one of the factors that play a role in identifying certain objects. The classification of guava fruit can be seen from the shape, texture and color. The shape of the guava fruit is quite diverse ranging from round (Round shape) to oval (Pear shape). So a Matlab application was built to determine the type of guava based on its color, shape and texture. K-Nearest Neighbor can classify objects based on learning data that is closest to the object so that the results can be more accurate. Principal Component Analysis (PCA) is a statistical technique for simplifying many-dimensional data sets into lower dimensions (extration features). The combination of K-Nearest Neighbor with Principal Component Analysis produces a fairly high accuracy for determining the type of guava using a total of 45 images and divided into two data including training data with a total of 36 guava data and test data with a total of 9 guava data.
