Pengaruh Sikap Profan terhadap Paradigma Masyarakat Beragama Perspektif Emile Durkheim
Authors: Khair Nurul
Published: February 2022

In recent developments the profane attitude produces fictional knowledge in understanding religious symbols, as a result religion is not seen as something sacred but a medium to achieve goals based on passion. The development of this paradigm, due to the power of human perception in understanding religious symbols. The power of perception increases the power of human imagination involving impulse in the self. This paper is an analysis of Emile Durkheim's thoughts about the profane attitude towards the paradigm of religious society. This paper aims to determine the influence of profane attitudes in shaping the framework of religious communities and providing solutions to the low paradigm of religious communities in understanding religious symbols. Aqliyah approach is a fundamental solution to overcome these problems. Durkheim explained that the process of uniting nature, humans, and God was due to the work process of reason, as the application of totem societies in understanding religious symbols. The implication, is to increase human existence in the religious frame and provide solutions as a form of attention to the lack of human knowledge in understanding the concept of religion

To counteract the effects of climate change and biodiversity loss, sustainable transformations of societal systems and processes, as well as spatial planning, are required. Ecosystem services are considered as a concept that could transform the management of natural resources towards more sustainability. On the basis of six application-oriented research projects, this paper analyses the extent to which transformation has played a role in planning-related research on ecosystem services so far and what potential experts see for contributing to transformative change in the context of spatial planning by means of ecosystem services. The current research projects on ecosystem services predominantly do not directly refer to transformative processes and strive for changes within the existing planning framework. However, if research would be designed accordingly, it would be possible to contribute to transformative processes. Among other things, the concept of ecosystem services can be used to promote system thinking, cross sectorial boundaries, or involve civic stakeholders to a greater extent. Experiments in research could be the basis for transforming the planning system starting at the niche level.

This study investigates the effect of block heterogeneity on corporate value in publicly-listed Korean companies during 2010-19. This study also examines whether there is a difference in the effect of blocks heterogeneity on Chaebol companies and non-Chaebol companies. We use block identities, portfolio sizes, and investment horizons as measures for blocks heterogeneity. We also use Tobin's Q as a proxy for corporate value. The results show that there is a significant positive relationship between blocks heterogeneity and company value. This study also shows that blocks heterogeneity has a stronger influence on non-Chaebol companies than Chaebol companies. This means that there is a difference between Chaebol companies and non-Chaebol companies in the effect of block heterogeneity on firm value. This suggests that there will be both synergies and diversity benefits among blocks of nonChaebol companies rather than Chaebol companies in the Korean stock market. This study is meaningful in that this study provides investors and business practitioners with information on the relationship between block heterogeneity and company value.

Travelling is considered one of the best ways to escape one’s day-to-day routine activities. Tourists’ travel is driven by several motivational factors, which lead them to plan or continue on a travel trip. However, since the emergence of COVID-19, travelling has become a major issue for the whole travel industry. The recent spread of Omicron makes most post-pandemic studies futile. Therefore, the purpose of this study was to examine the influence of motivation factors that affect tourists’ travel intention in the controlled pandemic context. The mediating role of perceived value and the moderating role of perceived travel risk were examined as well. The Stimulus-Organism-Response (S-O-R) theory was adopted as the theoretical foundation of the research framework. A quantitative online survey was used to collect data from 388 Malaysian and Taiwanese travelers. Partial least squares structural equation modelling (PLS-SEM) was employed to analyse the data. The results show that escape, kinship, and people are direct and indirect motivation factors that influence tourists’ intention to travel via perceived value. Notably travel risk indicated no moderating effect. The results of this study provide useful insights into tourists’ post-pandemic behaviour that offer practical implications for Asian business.
Kyiv metro and urban imageability: a student youth vision
Authors: Gnatiuk Olexiy , Kononenko Olena , Mezentsev Kostyantyn
Published: February 2022

This paper aims to reveal and explain the role of metro stations in a post-socialist metropolis as nodes that determine the perception of the city. By means of Lynch-type mental maps, we sought to find whether metro stations really function as perceptual nodes concentrating urban functions and traffic, and how recent changes of urban built environment and functions induced by neoliberal policy are reflected in the public perception. The results are discussed in relation to transit-oriented development that considers public transport stations and spaces around them as community hubs. The study has confirmed the expectation that the metro system constitutes an important part of the urban image and often functions as a skeleton that is used to arrange and frame the mental map of the city. Most of the metro stations function as perceptual nodes concentrating a particular urban function (monofunctional nodes) or combination of different functions (multifunctional nodes). The current perception of nodal areas around the metro stations reflects the recent transformation of urban built environment and functions, including intense and sometimes aggressive commercialization, as well as deindustrialization, although the role of open green public spaces and waterfronts continues to be important. To promote economic development and produce a more comfortable living environment, the metro-related nodal areas need to balance different functions, resisting abusive commercialization and promoting, keeping, and creating open public spaces, green areas and heritage protections.
Case report of a novel mutation in Bruton’s tyrosine kinase gene with confirmed agammaglobulinemia and absent B lymphocytes
Authors: Bedaiwy Nouf , Alhamdi Shatha , Al Suwairi Wafaa , Alsalamah Mohammad
Published: February 2022

Background: X-linked agammaglobulinemia type 1 (XLA) is one of the most common pediatric inborn errors of immunity affecting the humoral immune system. The condition is caused by a mutation in the Bruton’s tyrosine kinase gene (BTK), located in the long arm of the X-chromosome. BTK is crucial for B lymphocyte differentiation and activation. Therefore, a defect in BTK results in B lymphocyte maturation arrest, absence of plasma cells, and failure of immunoglobulin production. XLA affected individuals present with a history of frequent severe pyogenic infections such as pneumonia, conjunctivitis, otitis media, and bacteremia. Laboratory evaluation classically reveals undetectable immunoglobulins and the absence of B cells. The mainstay treatment is immunoglobulin replacement which can be administered intravenously (IVIG) or subcutaneously (SCIG). Aggressive antimicrobial treatment is also administered to reduce complications such as bronchiectasis or invasive bacterial infections during active infections.

Aim: To report the clinical presentation, immune features, and genetic mutation in a case of a four-year-old boy with a novel mutation in the BTK gene leading to XLA.

Results: The patient’s chart was reviewed. We describe the phenotypical and diagnostic characteristics of an established case in a four-year-old boy who suffered from recurrent infections. Genetic analysis revealed a pathogenic novel mutation in the BTK gene (c.1953C>A; p.Tyr651*), while flow cytometry found 0% CD19+ (B cells), and low serum Ig levels.

Discussion: We report the clinical presentation, immune features, and genetic mutation in a patient with a novel mutation in the BTK gene causing XLA. Genetic analysis along with patient history, physical examination, and laboratory results are necessary to identify and diagnose XLA associated with pathogenic mutations in the BTK gene.

Statement of novelty: We present an established case of a novel mutation in the BTK gene (c.1953C>A; p.Tyr651*), based on genetic analysis, absent CD19+cells (B cells), and low Ig serum levels.
Generalized Approach/Avoidance Responses to Degraded Affective Stimuli: An Informational Account
Authors: Pillaud Nicolas , Ric François
Published: February 2022

Two studies tested whether affective stimuli presented auditorily spontaneously trigger approach/avoidance reactions toward neutral visual stimuli. Contrary to hypotheses, Experiment 1 revealed that when the target was present, participants responded faster after positive (vs. negative) stimuli, and faster to the absence of the target following negative (vs. positive) stimuli, whatever the response modality (i.e., approach/avoidance). Instructions were to approach/avoid stimuli depending on whether a target was presented or not presented. We proposed that affective stimuli were used in this study as information about the presence/absence of the target. In Experiment 2, we replicated the results of Experiment 1 when participants responded to the presence/absence of the target, whereas an approach/avoidance compatibility effect was observed when each response modality was associated with a target. These results indicate that affective stimuli influence approach/avoidance across perceptual modalities and suggest that the link between affective stimuli and behavioral tendencies could be mediated by informational value of affect.

Published: February 2022

DRG neurons are classified into distinct types to mediate the somatosensation with different modalities. Recently, transcriptional profilings of DRG neurons by single-cell RNA-sequencing have provided new insights into the neuron typing and functional properties. Zinc-finger CCHC domain-containing 12 (Zcchc12) was reported to be the representative marker for a subtype of galanin-positive (Gal+) DRG neurons. However, the characteristics and functions ofZcchc12+neurons are largely unknown. Here, we genetically labeledZcchc12+neurons inZcchc12-CreERT2::Ai9 mice, and verified thatZcchc12represented a new subpopulation of DRG neurons in both sexes.Zcchc12+neurons centrally innervated the superficial laminae in spinal dorsal horn, and peripherally terminated as free nerve endings in the epidermis and cluster-shaped fibers in the dermis of footpads and nearby. In addition,Zcchc12+neurons also formed circumferential endings surrounding the hair follicles in hairy skin. Functionally,in vivocalcium imaging in DRGs revealed thatZcchc12+neurons were polymodal nociceptors and could be activated by mechanical and noxious thermal stimuli. Behavioral tests showed that selective ablation ofZcchc12+DRG neurons reduced the sensitivity to noxious heat in mice. Together, we identified a new subpopulation ofZcchc12+nociceptors essential for noxious heat sensation.

SIGNIFICANCE STATEMENTZcchc12represents a new subpopulation of DRG neurons. The characteristics and functions ofZcchc12+neurons are largely unknown. Here we genetically labeledZcchc12+neurons, and showed that the fibers ofZcchc12+DRG neurons projected to superficial lamina at spinal dorsal horn, and innervated skin as free nerve endings in the epidermis and cluster-shaped fibers in the dermis of footpads and nearby. Functionally,Zcchc12+DRG neurons responded to noxious mechanical and heat stimuli. Ablation ofZcchc12+DRG neurons impaired the sensation of noxious heat in mice. Therefore, we identify a new subpopulation of DRG neurons required for noxious heat sensation.

Published: February 2022

Heat Conduction is a scientific concept that related to daily life. Learning about heat conduction is usually only discussed at the macroscopic level, whereas at the sub-microscopic level never be a concern from elementary students until to the teachers. This study aims to identify the effect of using Conceptual Change Text on the teacher's representation on the Â heat conduction concept. A quasi-experimental method using a one-group pretest-posttest design was used in this study. The instrument was a diagnostic test, the data were analyzed from the comparison of participants' representations (5 elementary teachers) before and after treatment, the results showed that teacher representation was better after treatment. This research also reinforces that the representation of the sub-microscopic level is an important aspect of the learning process. Science learning needs to be developed and equipped up to the sub-microscopic level both verbal or visual to make science lessons more meaningful and easily understood by students.

Published: February 2022

Stress drop is a fundamental parameter of earthquake source that describes stress before and after an earthquake. The purpose of this study was to determine the tectonic characteristics of the Banda sea region. The research method used is a mathematical analysis and Nelder Mead Simplex nonlinear inversion methods. The results show that the Banda Sea is the area with complex tectonic conditions and large earthquake impacts. The Banda sea earthquake generated a stress drop of between 2 MPa -10 MPa from small to medium, it can be concluded that the rocks in the Banda Sea are relatively harder because the Banda Sea has a complex and varied oceanographic profile. The Banda Sea contains many continental fragments and has very deep ocean basins in the North Banda and Weber Deep, as well as plate rollbacks that form geometry in the shape of a spoon. The strength of rocks in the Banda Sea is also strengthened by the results of gravitational anomalies, there are significant differences in the gravity anomalies around the Banda ocean which indicate high density. This information is very important to know the amount of pressure released shortly after the earthquake which has a very large impact as a disaster mitigation measure.Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â

Personal protection equipment for orthopaedic and trauma surgery during the COVID-19 pandemic: The results of an EFORT survey initiative
Authors: Karachalios Theofilos , Maasalu Katre , Felländer-Tsai Li
Published: February 2022

Orthopaedic and trauma surgeons performing surgery in the COVID-19 pandemic environment faced problems with availability, use, rationing, modification, compliance and recycling of personal protection equipment (PPE).

Orthopaedic and trauma surgeons were not well informed concerning the use of PPE for aerosol-generating orthopaedic and trauma procedures.

Scientific bodies, health authorities and management have provided insufficient guidelines for the use of PPE in aerosol-generating orthopaedic and trauma procedures.

The availability of specific PPE for orthopaedic and trauma operating theatres is low.

Hospital management and surgeons failed to address the quality of operating theatre ventilation or to conform to recommendations and guidelines.

Operating theatre PPE negatively affected surgical performance by means of impaired vision, impaired communication, discomfort and fatigue.

Existing PPE is not adequately designed for orthopaedic and trauma surgery, and therefore, novel or modified and improved devices are needed.
Assessing maternal thyroid function and its relationship to duration of the first stage of labor

Published: February 2022

Introduction

Maternal thyroid function plays a critical role in the normal labor process. Whether maternal thyroid function affects the duration of the first stage of labor is still unknown.

Methods

Maternal serum levels of free thyroxine (FT4), thyroid-stimulating hormone (TSH) and thyroid peroxidase antibody (TPOAb) were detected in 31,382 pregnant women. A multiple linear regression model was applied to investigate the effect of maternal thyroid function on the duration of the first stage of labor.

Results

FT4 level in the second trimester and in the third trimester was found to be negatively associated with duration of the first stage of labor (β = −1.30 h, 95% CI: −2.28, −0.32, P < 0.01; β = −0.35 h, 95% CI: −0.61, −0.10, P < 0.01). TSH level in the third trimester was found to be positively associated with the duration of the first stage of labor (β = 0.12 h, 95% CI: 0.06, 0.18, P < 0.001). Per unit increase in TPOAb (IU/mL) in the second trimester and in the third trimester was significantly associated with prolonged first stage of labor (β = 0.08 h, 95% CI: 0.01, 0.14, P = 0.02; β = 0.09 h, 95% CI: 0.02, 0.15, P = 0.01). For pregnant women suffering from subclinical hypothyroidism combined without TPOAb, TSH level in the third trimester exhibited a significant positive association with the length of the first stage of labor (β = 2.44 h, 95% CI: 0.03, 4.84, P = 0.04).

Conclusions

These findings suggest that maternal FT4, TSH and TPOAb might be important predictors of the first stage of labor.

Published: February 2022

This article has two objectives. First, it exposes the appearance of the Craftsmen Society (1874) as one of the first craftsmen organizations in Costa Rica that it allowed the worker merger and solidarity, and second, it recovers the worker instruction projects that such association had. The analysis is based on the historical recovery of the organization from the treatment of the El Artesano newspaper mainly, its official publishing medium. It was analyzed a total of fifty copies. It concluded that the Craftsmen Society was constituted in a fundamental base to understand the first trace of the worker craftsmen organization configuration in the country and their cultural and educational objectives especially due to the education projects made in 1889, which they strongly influenced the worker culture.

Authors: Ordoñez Cash Fernando , Porras Calderón Alexander Stefano
Published: February 2022

During the established period, the region and later city of Limón became a diverse socio-cultural area due to the heterogeneous migration that populated their lands. It caused that the celebration of the independence of Costa Rica, in its «Limonense» variant, was different from the one celebrated in the main cities of the Central Valley. The written press releases that are presented below give a sample of how this national holiday was celebrated by the city of Limón and of the rejection speeches —from the Central Valley— towards Limón, its inhabitants and how they celebrated the festival.

Two Narratives about Kosovo’s Political Friends: A Critical Discourse Analysis of Articles in Two Newspapers
Authors: Muzbeg Esin , Tahiri Lindita
Published: February 2022

This article analyzes the portrayal of the USA and NATO as Kosovo’s friends in the Kosovan media discourse. The research will use the Critical Discourse Analysis based on the model by Van Dijk to demonstrate the production and continuity of the friendship discourse in the Kosovan media. Two daily media outlets are analyzed: Koha Ditore and Epoka e Re, focusing on the strategies used to construct the image of Kosovo’s friends for the countries that have supported the independence of the new state of Kosovo. The ideological framing of the friendship discourse is pointed out as the dominant topic in these two mainstream newspapers, but on the other hand, the papers emphasize two different perspectives of using the discourse of friendship, which are adjusted to the editorial policies and persuasive goals of the respective papers.
The role of perinatal testosterone on exploratory behavior, sexual motivation, and spatial working memory in adult rats
Authors: Gopalan Chaya , Niepoetter Paige , Ogle Avery , Medavaka Sai , Olendorff Samantha A , Tucker Kevin R
Published: February 2022

Aim: Sex differentiation occurs during the perinatal period (four days before and after birth) in the rat brain. The brain remains a female brain unless exposed to testosterone, which gets metabolized to 17β-estradiol and dihydrotestosterone. While aromatase converts testosterone to 17β-estradiol, 5α-reductase converts testosterone to dihydrotestosterone. 17β-estradiol exerts its effects by binding to an estrogen receptor, whereas dihydrotestosterone via an androgen receptor. The role of dihydrotestosterone and 17β-estradiol during the organizational phase of brain differentiation was tested using adult rat behaviors. The study sought to examine the effects of perinatal manipulations on adult rat behaviors. Materials and methods: Timed-pregnant rats received either the vehicle (5% ethanol and 95% sesame oil), exemestane (4 mg/kg/ml; aromatase inhibitor), or flutamide (20 mg/kg/ml; androgen receptor blocker) subcutaneously during the last four days of pregnancy. Pups from each group continued to receive their treatments during the first four days after birth. From postnatal day 65, these animals were subjected to open field, sexual motivation, and spatial working memory tests. Results: Male rats receiving flutamide exhibited exploratory behavior significantly more compared to exemestane and control groups. Male rats receiving exemestane had substantially higher plasma testosterone and displayed an increased interest in the estrus rat than the control and flutamide group. Conclusion: Androgen receptor blockade resulted in increased exploratory behavior in male rats where 17β-estradiol was testosterone's primary metabolite. The blocking of aromatase using exemestane resulted in higher levels of plasma testosterone and enhanced sexual motivation in male rats. Thus, 17β-estradiol and dihydrotestosterone's presence during the organizational phase is essential for normal socio-sexual and exploratory behaviors.

The aim of this work was to study the influence of the use of air cooling means in easily assembled premises on the behavior and comfort of cows during periods of dangerous value of the temperature-humidity index (THI). The research was conducted during July 2020 in the central part of Ukraine (Kyiv region, Bila Tserkva district) during a long high-temperature load. The value of the daily ambient air temperature ranged from +19 to +34°С, and the relative humidity was 46–78%. Two farms with loose cows and different animal comfort options were selected for the study. The first option is to be loose in an easy-to-assemble room with fans installed above the aft table to cool the air. Fan hours from 12:00 to 17:00. The second option is loose keeping in an easy-to-assemble room on a deep, long-lasting straw litter. It was found that the use of ventilation systems allowed to reduce by 5.3°C the average daily values of air temperature compared to keeping on deep litter without ventilation systems. The values equivalent temperature index (ETI) and the index of equivalent temperature for cattle (ETIC), which indicate the level of sensitivity of the body during prolonged high temperatures, were lower by 1.63°C, and ETIC by 1.11 compared to keeping in deep litter without systems ventilation. The duration of lying down under the option of keeping cows using air cooling elements was higher by 68 min/day compared to keeping on deep litter without air cooling elements. In a cowshed with ventilation systems, the energy consumption for heat transfer of the body was 63.1 MJ, which is 5.4 MJ lower than in a cowshed on deep litter without the use of ventilation systems.

The state of the antioxidant system of protection of honey bees Apis mellifera carnica under the action of different temperatures in order to optimize the temperature regime to keep of bee colonies indoors during the winter was studied. Bee colonies of 81–91-day-old worker bees were transferred from the territory of the Yuriy Fedkovych Chernivtsi National University apiary during the period of sharp changes in temperature (the end of November) in constant conditions of the buildings (5±0.6°С and 14±0.8°C) and were kept there for 12 weeks. The selection of worker bees for biochemical analysis was performed 7 times every two weeks. The level of TBA-active products (TBARS), catalase (CAT) and glutathione-S-transferase (GST) activity in insect tagmas (head, thorax and abdomen) were studied. It has been found that the transfer of bee colonies from unstable temperature conditions to stable ones, regardless of their value, leads to a decrease in the flow rate of lipid peroxidation (TBRAS level) against the background of increasing activity of enzymes (CAT та GST). The tagmospecific response of the antioxidant system of honey bees depending on the wintering temperature was revealed. Keeping bee colonies indoors at constant temperatures (for ten weeks) was accompanied by certain coherence in the work of the antioxidant system of insects. In particular, the TBRAS level, as well as the activity of enzymes, did not change significantly during the study. However, in early February (at the end of the experiment), regardless of the building temperature, the TBARS level was increased in the tissues of the bee’s head, and in the tissues of the abdomen the GST activity was intensified. At the same time, in the middle of winter (on January), the level of TBARS in bees, that were kept at +5°С, was lower in comparison with bees that wintered at +14°С. The optimal temperatures for keeping bee colonies in winter indoors was proposed: for bee colonies of medium strength at temperatures around +5°С, and for bee colonies of weak strength around +14°С by the end of January with further temperature decrease to +10°С.

Проведено дослідження спектрального складу, квантового виходу і просторового розподілу випромінювання збуджених частинок, що покидають поверхню системи органічний барвник–ліпід, під час бомбардування іонами аргону. Встановлено, що наявність у мішені ліпідів змінює кількість збуджених частинок, що покидають поверхню, відносно чистого барвника. На основі отриманих результатів зроблено висновки щодо механізму впливу ліпідів на вихід збуджених частинок.

У роботі запропоновано вдосконалений поляризаційний потенціал Стілінджера і Девіда для міжмолекулярної взаємодії у воді. Сформульовано чіткий алгоритм визначення функції, яка описує взаємодію оксиген–гідроген в молекулі води. Розроблено новий підхід до моделювання функції, що екранує заряд-дипольну взаємодію на малих відстанях. Для правильного опису асимптотичної поведінки міжмолекулярного потенціалу на достатньо великих відстанях потенціал Стілінджера і Девіда завершено взаємодією між дипольними моментами оксигенів. Крім того, поляризаційна складова потенціалу Стілінджера і Девіда доповнена доданком, що описує деформацію електронних оболонок оксигенів. Узагальнення потенціалу Стілінджера і Девіда дозволяє успішно відтворити всі основні результати квантово-хімічних розрахунків енергій взаємодії двох молекул води, отриманих Клементі.

Annealing Effects on FluctuationInduced Conductivity of (Cu0.5Tl0.25Hg0.25)Ba2Ca3Cu4O12-δ, Superconductor

Published: February 2022

In the light of the Aslamazov–Larkin theory of fluctuation-induced conductivity (FIC), the excess conductivities of as-prepared, nitrogen-post-annealed, oxygen-post-annealed, and air-post-annealed samples of (Cu0.5Tl0.25Hg0.25)Ba2Ca3Cu4O12–δ have been determined. It is observed from FIC measurements that the crossover of a three-dimensional (3D) to a two-dimensional (2D) behavior of fluctuations is shifted to higher temperatures by the post-annealing of samples in nitrogen, oxygen, and air. We have accredited this behavior to an increase in the grain size and the improved carrier concentration in the conducting CuO2 planes. In addition, it is also noted that, after the post-annealing of samples in nitrogen, oxygen, and air, the width of the three-dimensional region of fluctuations is also enlarged. Furthermore, two distinct parameters (coherence length and interplanar coupling) are also estimated by the Lawrence–Doniach equations and found to be increased by the post annealing in nitrogen, oxygen, and air.

Методами високороздільної X-променевої дифракції (ВРХД), комбінаційного розсіяння світла (КРС) і фотолюмінесценції (ФЛ)досліджено вплив параметрів буферного шару Si1–xGex на просторове впорядкування самоіндукованих наноострівців Gе убагатошарових структурах SiGe/Si, вирощених на (001)Si підкладках. Показано, що товщина та компонентний склад Si1–xGex буферного шару впливають на латеральне впорядкування наноострівців завдяки різній чутливості до впорядкованої модуляції деформацій на поверхні шару. Встановлено, що просторове впорядкування задається виключно латеральнимвпорядкуванням уже в першому періоді надґратки (НҐ). Показано, що у випадку товстих Si1–xGex буферних шарів із значним вмістом Ge починається пластична релаксація з виникненням дислокацій невідповідності на межі поділу, а шари НҐ є когерентними до буферного шару. Комплексні дослідження структурних та оптичних характеристик дозволили отримати методичні підходи до дослідження впорядкування наноострівців у НҐ.

Published: February 2022

The problem of the CO adsorption and dissociation on the Mo(110) surface has been studied by means of temperature-programmeddesorption (TPD) and density-functional (DFT) calculations. The TPD spectra show a first-order CO desorption, which indicates thedesorption from a virgin state, not a recombinative form of desorption. The height of the potential barrier for CO dissociation (2.75 eV), estimated from DFT calculations, substantially exceeds the energy of CO chemisorption on the Mo(110) surface (2.1 eV), which refutes a thermally induced CO dissociation. Monte Carlo simulations of TPD spectra, performed with the use of estimated chemisorption energies, are in good agreement with experiment and demonstrate that the two-peak shape of the spectra can be explained without involving the CO dissociation.

Humanistic outcomes such as quality of life are very important parameters for assessing the success of chemotherapy. Therefore, this study aimed to evaluate the impact of using the cisplatin-vincristin-bleomycin regimen before and after chemotherapy on quality of life. It was conducted using a cross-sectional design in inpatients at Dr. Hasan Sadikin Bandung from June 2015 to March 2016. The data were taken prospectively by field observation. The patient's quality of life was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) questionnaire. Furthermore, the difference in domain values before and after chemotherapy was evaluated statistically by paired t-test (p<0.05). The results show an increase in all aspects of the functional domain, except social functions. There was a tendency to reduce the symptom domain except for decreased appetite (p=0.009). The domain of global health status increased significantly after chemotherapy (p=0.000). Overall, using the cisplatin-vincristin-bleomycin regimen for three cycles improves the quality of life of cervical cancer patients.

Treatment of breast cancer with chemotherapy in several cycles has led to differences in patients' quality of life. One of the chemotherapy recommendations for breast cancer is Cyclophosphamide-Doxorubicin-5Fluorouracil (CAF). Therefore, this research aimed to determine the quality of life among chemotherapy cycles with CAF in breast cancer patients at Dr. Zainoel Abidin Hospital Banda Aceh. This is an observational analytic study with the cross-sectional method, where 32 patients were obtained through a total sampling technique from June to August 2019. Quality of life was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C-30), while the Kruskal-Wallis test performed the statistical analysis. The results showed that the quality of life of breast cancer patients has no significant difference among chemotherapy cycles with CAF (p>0,05). However, some changes in the functional and symptom scale among patients required a further follow-up by healthcare professionals to improve the quality of life.
