Authors: Chaudhury Sushovan , Sau Kartik , Shelke Nilesh , Rashid Zahraa M.
Published: July 2022

Background:

The study of breast cancer detection begins with the WBCD dataset for most researchers, as it is a very well-known dataset. We use this dataset as a benchmark in this paper to study ML algorithms like SVM, DT, RF, KNN, NB classifiers, Logistic Regression, Extra Trees, Bagging Classifiers with hard and soft voting, Ensemble techniques and Extreme Gradient Boosting classifiers like XG Boost and 2 deep learning models with regularization and without regularization.

Objective:

The primary objective is to revisit how the existing classifiers fare with the WBCD dataset and suggest a method with Grid search and Randomized search by selecting the best hyper-parameters to apply with and without PCA and check if WBCD dataset can be classified in lesser time without compromising accuracy.

Method:

We explore PCA as a feature extraction technique in this dataset and use techniques like Feature Scaling K Fold stratified cross-validation technique, K best etc. We implement Grid search CV along with PCA in the pipeline to tune the hyper parameters across various classifiers and reduce the training and prediction time without compromising accuracy. Last but not the least, this paper also compares the accuracy, precision and recall of various ML techniques for manually selected features by observing the feature importance score and the correlation matrix.

Results:

In our experiment with all features, we get an accuracy of 97.9 per cent for Extra trees and Ensemble techniques with RF, KNN and Extra Trees with soft voting strategy and using feature selection with PCA and grid search we get an accuracy of 99.1 per cent with SVM (kernel trick). We also demonstrate that the running time of training and prediction also reduces if hyper parameters of classifiers are tuned appropriately which is taken care of by Grid and Randomized Hyper Parameter Grids.

Conclusion:

It is shown in this paper that Feature subset selection or feature ranking may not be the best way and not the only way to be applied on WBCD dataset along with PCA. In datasets where features are closely correlated , a method for hyper parameter tuning using either Grid or Randomized Search can be accompanied with PCA to extract the best feature combinations and then fed into the classifiers to get good accuracy scores and can be executed in a much quicker time.

Authors: Luna-Colombo Sabando Martín , Ávila-Rosales Francisca Margarita
Published: July 2022

The research was carried out with the objective of analyzing the school performance in learning in the students at the secondary school of the Magdalena Dávalos Educational Unit No. 32 of the Tosagua canton, a situation that arose due to problems of interests caused by difficulties of ignorance in the area’s basics such as language and literature, mathematics, natural sciences and social studies that are essential in the comprehensive education of students. Since parents are permissive in the development and fulfillment of school tasks, it was hypothesized how school performance affects the learning of middle school students. The relevance of meaningful learning is meaningful teaching, which uses the student's prior knowledge to build new instruction. The teacher is a mediator between the knowledge and the students who participate, being a receiver to learn. School performance is a topic of interest and concern for educators and school authorities as it is an inherent element in the quality and efficiency of the educational process.
Sentencing over Objection to Mobilization as Military Reserve: An analysis of National and International Laws
Authors: Madjid Abdul
Published: July 2022

Law Number 23 of 2019 concerning National Resource Management for State Defense does not regulate conscientious objection, which refers to the right of a person to refuse to participate in a war or military service on the grounds of religion and morality. Their absence in such services is replaced by other responsibilities such as working in public health services, providing security, and being involved in other social services. Article 77 Paragraph (1) of Law Number 23 of 2019 expressly provides for sentences that should be imposed on those who refuse to serve as a military reserve, where the rule is not in accordance with the principle of conscientious objection which gives a person the right to refuse on the basis of conscience. This research discusses the legal consequences of the enactment of two rules regarding military service and the application of different conscientious objections. This study applied normative juridical methods and approaches to examine the consistency and relevance of various statutes and government regulations that govern conscientious objection. This study also used conceptual and statutory approaches to explore why conscientious objection is considered a ground for refusal to participate in conscription according to International Human Rights Law. The findings revealed that the conception of defense and compulsory military service in Indonesia does not leave any chance to guarantee the rights of citizens to refuse to participate in military service according to the conscience and belief of every individual (conscientious objection). This is in contrast to the regulatory provisions of international human rights ratified by Indonesia under the International Covenant on Civil and Political Rights. Additionally, there is a need for clear arrangements regarding conscientious objection and the requirements that must be met by citizens who submit these principles for the rejection of military service in Indonesia.
Turnover and Recommendation Intentions in the Post-Implementation Period of Radical Decentralization
Authors: Street Chris , Feeney Justin R.
Published: July 2022

Radical Decentralization (RD) is a form of self-management where the authority and decision-making relationship between manager and subordinate is eliminated. A popular RD structure is Holacracy, which pushes decision-making down to the individual employee level. We examined Holacracy adoption within a Canadian technology with 445 employees using a mixed-methods design. We found that the perceived efficacy of RD was contingent on the extent that employees felt there was authentic leadership, efficient administration, role clarity, and role accountability. Perceived efficacy of RD positively predicted employee motivation, which facilitated lower turnover intentions and intent to recommend the organization to others.
Professionals with Disabilities: Crafting Career Success and Engagement
Authors: Barclay Lizabeth A. , Markel Karen S.
Published: July 2022

Research and public policy suggest that organizations have a responsibility to create supportive environments for people with disabilities. These individuals continue to face barriers and often find themselves underemployed relative to their skills. Previous research focuses on barriers to employment. This paper explores the career strategies and work engagement of people with disabilities with careers that reflect their educational accomplishments. Qualitative data analysis revealed that study participants proactively shaped their environments through job crafting independent of human resource management or organizational policies. By focusing on examples of career success, this research provides new perspectives on the integration of this population into the work environment.
Wearable Devices in Diving: Scoping Review
Authors: Bube Benjamin , Zanón Bruno Baruque , Lara Palma Ana María , Klocke Heinrich
Published: July 2022

Background

Wearables and their benefits for the safety and well-being of users have been widely studied and have had an enormous impact on the general development of these kinds of devices. Yet, the extent of research into the use and impact of wearable devices in the underwater environment is comparatively low. In the past 15 years, there has been an increased interest in research into wearables that are used underwater, as the use of such wearables has steadily grown over time. However, there has so far been no clear indication in the literature about the direction in which efforts for the design and construction of underwater wearable devices are developing. Therefore, the analysis presented in this scoping review establishes a good and powerful basis for the further development and orientation of current underwater wearables within the field.

Objective

In this scoping review, we targeted wearable devices for underwater use to make a comprehensive map of their capabilities and features and discuss the general direction of the development of underwater wearables and the orientation of research into novel prototypes of these kinds of devices.

Methods

In September 2021, we conducted an extensive search for existing literature on 4 databases and for grey literature to identify developed prototypes and early-stage products that were described and tested in water, could be worn and interacted with (eg, displays, buttons, etc), and were fully functional without external equipment. The studies were written in English, came from peer-reviewed academic sources, and were published between 2005 and 2021. We reviewed each title and abstract. The data extraction process was carried out by one author and verified by another author.

Results

In total, 36 relevant studies were included. Among these, 4 different categories were identified; 18 studies dealt primarily with safety devices, 9 dealt with underwater communication devices, 7 dealt with head-up displays, and 2 dealt with underwater human-computer interaction approaches. Although the safety devices seemed to have gained the most interest at the time of this study, a clear trend toward underwater communication wearables was identified.

Conclusions

This review sought to provide a first insight into the possibilities and challenges of the technologies that have been used in and for wearable devices that are meant for use in the underwater environment. Among these, underwater communication technologies have had the most significant influence on future developments. Moreover, a topic that has not received enough attention but should be further addressed is human-computer interaction. By developing underwater wearables that cover 2 or more of the technology categories that we identified, the extent of the benefits of such devices can be significantly increased in the future.

Authors: Scott Andrew F , Ayers Stephanie , Pluye Pierre , Grad Roland , Sztramko Richard , Marr Sharon , Papaioannou Alexandra , Gerantonis Patricia , Levinson Anthony J
Published: July 2022

BACKGROUND

Care partners of people living with dementia may benefit from online education. We developed iGeriCare, an award-winning internet-based platform with 12 multimedia e-learning lessons about dementia.

OBJECTIVE

Our objective was to evaluate users’ perceptions of impact.

METHODS

From March 17, 2021-May 16, 2022, data were collected upon lesson completion. We used the content-validated Information Assessment Method for patients and the public (IAM4all) adapted for dementia care partners. The IAM4all questionnaire assesses outcomes of online consumer health information. Responses were collected using SurveyMonkey.

RESULTS

409 responses were collected, with a 95% survey completion rate. 44% identified as a family or friend care partner, and 21% as an individual concerned they may have mild cognitive impairment (MCI) or dementia. 93% identified the lesson as relevant (29%) or very relevant (64%). 99% understood the lesson well or very well. Respondents were motivated to learn more (58%), taught something new (54%), validated what they do (53%), reassured (47%), or refreshed their memory (38%). 98% said they would use the information: in particular, to better understand something (71%), discuss the information with someone else (52%), do things differently (34%), or do something (31%). Most free text feedback comments reported a positive sentiment.

CONCLUSIONS

Users identified iGeriCare as relevant, beneficial, and that they would use the information. To our knowledge, this is the first time the IAM4all has been used to assess patient and caregiver feedback on internet-based dementia education resources. A randomized controlled trial to study feasibility and impact on caregiver knowledge, self-efficacy, and burden is planned.

BACKGROUND

Some children and adolescents suffer from late effects of a SARS-CoV-2 infection despite a frequently mild course of the disease. Nevertheless, extensive care for post–COVID-19 condition, also known as post–COVID-19 syndrome, in children and young people is not yet available. A comprehensive care network, Post-COVID Kids Bavaria (PoCo), for children and adolescents with post–COVID-19 condition has been set up as a model project in Bavaria, Germany.

OBJECTIVE

The aim of this study is to evaluate the health care services provided within this network structure of care for children and adolescents with post–COVID-19 condition in a pre-post study design.

METHODS

We have already recruited 117 children and adolescents aged up to 17 years with post–COVID-19 condition who were diagnosed and treated in 16 participating outpatient clinics. Health care use, treatment satisfaction, patient-reported outcomes related to health-related quality of life (the primary endpoint), fatigue, postexertional malaise, and mental health are being assessed at different time points (at baseline and after 4 weeks, 3 months, and 6 months) using routine data, interviews, and self-report questionnaires.

RESULTS

The study recruitment process ran from April 2022 until December 2022. Interim analyses will be carried out. A full analysis of the data will be conducted after follow-up assessment is completed, and the results will be published.

CONCLUSIONS

The results will contribute to the evaluation of therapeutic services provided for post–COVID-19 condition in children and adolescents, and avenues for optimizing care may be identified.

Analysis Design Results of Kort Nozzle on Yamaha 15 HP Outboard Motor Propulsion System Towards Increasing Ship Speed
Authors: Huka Brampi Stefie Hendry , Wibowo Berbudi , Maimun Maimun
Published: July 2022

Use of Yamaha outboard motors There are very many small farmers (tuna fishermen) with a capacity of 1.5 GT in the Leahari country, South Leitimur sub-district, Ambon city. Apart from being used for fishing, it should also be used to sell the catch to the receiving company, but in reality the sales process to the company uses a rental motorcycle taxi. One of the factors that need to be considered in the process of planning and building a ship is a good propulsion system, the propulsion system itself is Propeller design planning. Propeller is one aspect that must be planned properly in order to achieve the purpose of the ship's function in terms of speed. Propeller that uses a kort nozzle is called a ducthed propeller. The phenomenon that occurs in propeller enclosed in a tube (kort nozzle) is that the velocity of the water flow inside the tube is faster than the flow of water outside the tube resulting in lower pressure inside the tube than the pressure outside the tube. . This pressure difference results in an additional thrust (thrust). In this study, the method used is experimental and statistical tests in which the author will examine the use of a kort nozzle on the Yamaha 15 HP outboard motor propulsion system which is expected to increase the speed of the ship so that fishermen can use vessel to sell their tuna catches to receiving companies.

Published: July 2022

Data published by the Organization for Economic Cooperation and Development - OECD (2021), which took as a reference the Integrated System of Financial Administration of the Federal Government - SIAFI, indicate that, unlike the other members of the group, Brazil has reduced its investment in education among the years 2019 and 2020 (MEC, 2021). As if the particular way in which education has been administered in Brazil were not enough, the effects caused by the COVID-19 pandemic, a disease caused by the coronavirus (Sars-Cov-2), negatively marked the history of national education. Against this movement, the school teacher Olindina Roriz Dantas, implemented by AGRODAN in Pernambuco, has been standing out as an example of responsibility and social commitment in the field of irrigated fruit, recognized as a national leader in mango exports. Socializing the ideals that made this teaching unit an example to be followed was the challenge of this study, which demonstrates that it is possible to reconcile successful business practices with social commitment to the inclusive and sustainable development of a region located in the Brazilian semi-arid region.

Published: July 2022

Our goal was to gain a sense of sanitation and health-care infrastructure in a few Bangladeshi regions during the Corona period. Performing our duties during the Corona era was difficult. During the lockdown, we had to get the job done despite the people's opposition. We went to everyone's residence and assessed the sanitary system, but since they were afraid of Corona, many of them did not completely reveal their concerns. As a result, we had to deal with a slew of issues. Many people have avoided eating out as a result of the Corona problem. They’re sipping water that's boiled. During the corona time, we learnt about the reaction to human health awareness through the internet. Sanitation’s overarching goals are to offer a healthy living environment for everyone, safeguard, natural resources (such as the surface-water, ground-water and soil), and provide people with safety, security, and dignity when they defecate or urinate.

In the same perspective, a study was conducted to investigate the possibility of a possible constitutive association of the arbuscular mycorrhizal fungus Rhizophagus irregularis L. (previously named Glomus intraradices) with saffron. The trial was conducted in the field at the experimental station of the Faculty of Sciences of Oujda (Morocco) by applying 3 doses of R. irregularis inoculum: 2, 4 and 6 ml per corm (T1, T2 and T3 treatments). Six months after planting, morphological, biochemical and mycorrhization parameters were measured. The results showed that the inoculation of saffron roots by R. irregularis was successful, which induced a significant increase in the number of leaves, the weight of stigmas and the percentage of daughter corms with large diameter. Similarly, the total chlorophyll content was increased, the highest value was recorded for the T3 treatment in April (0.04 mg/g MF), with an increase of 25% compared to the control.

О старицком храмоздательстве в XVII веке
Authors: Салимов Алексей
Published: July 2022

На протяжении столетий обилие залежей белого камня (известняка) в Старице и её окрестностях делало этот город поставщиком данного строительного материала в различные земли нашей страны. Эти природные возможности Старица в полной мере использовала в средневековье, когда являлась вторым по значению городом Тверского княжества, а затем важным цен­тром в структуре Московского государства. В итоге в конце XIV - XVI веках здесь было выстроено несколько каменных храмов, художественные достоинства которых позволяют поставить их в один ряд с лучшими творениями зодчих Древней Руси.
После Смуты начала XVII века строительство каменных зданий в Старице надолго замирает. Позже оно возобновля­ется, но ведут его только в монастырях, поскольку Старицкий кремль в этот период - это постепенно пустеющая террито­рия с ветшающей и быстро разваливающейся крепостью. Наиболее ранней каменной постройкой XVII столетия стал собор Вознесенского монастыря. Созданный в середине века, возможно, не без участия царской фамилии, этот храм стилистически, по всей видимости, был близок московским культовым постройкам первой половины - середины XVII века с их богатым фасадным узорочьем.
Пожар, уничтоживший в 1681 году значительную часть застройки в старицком Успенском монастыре, способствовал тому, что в 80-е - 90-е годы XVII века здесь было выстроено несколько каменных корпусов, новая соборная колокольня и надвратная церковь Иоанна Богослова. Её объёмно-простран­ственная композиция «восьмерик на четверике» стала олицетворением тех новаторских архитектурных процессов, которые способствовали появлению на Руси нового типа храма.

Published: July 2022

Библиотечные классификаторы и Государственный рубрикатор научно-технической информации (ГРНТИ) рас­сматриваются в работе с точки зрения отражения в них архитектурного знания. Исследуется, к каким сферам обще­ственной практики отнесена архитектура, какова степень раз­витости, дифференцированности позиций классификаторов, как архитектурное знание представлено на фоне смежных областей - строительства и искусства, насколько системно и развёрнуто выглядит раздел теории архитектуры по срав­нению с теорией искусства. Обнаружено, что позициониро­вание архитектуры, количество рубрик, кодов, отводимых архитектурному знанию, его разветвлённость по уровням иерархии в целом и в отношении теории свидетельствуют о сравнительно худшем состоянии или менее информативной репрезентации архитектуры по сравнению со строительством и искусствоведением и о необходимости предпринимать усилия по исправлению ситуации.

Поиски принципов проектирования нового Юго-западного района Москвы в 1935-1941 годах (по материалам Института градостроительства Академии архитектуры СССР)
Authors: Старостенко Юлия
Published: July 2022

Статья посвящена истории разработки проектов пла­нировки и застройки Юго-западного района Москвы в период 1935-1941 годов. Изучение и анализ этих проектов стали возможны благодаря документам, вновь выявлен­ным в фонде Института градостроительства Академии архитектуры СССР в Российском государственном архиве в г. Самаре (РГА в г. Самаре. Ф. Р-147). Эти документы в совокупности с материалами Академии архитектуры СССР из Российского государственного архива экономики и малоизученными изданиями 1935-1940 годов позволили, в первую очередь, восстановить хронологию разработки проектов планировки Юго-западного района в период от принятия постановления СНК СССР и ЦК ВКП(б) «О Генеральном плане реконструкции г. Москвы» 1935 года, благодаря которому район был присоединён к Москве, и практически до начала Великой Отечественной войны. Они также позволили проследить, какие задачи решались на разных этапах проектирования и какие принципы лежали в основе организации жилой застройки нового района. Кроме того, архивные материалы дали возможность с качественно новых позиций увидеть роль Института гра­достроительства Академии архитектуры СССР и его Мастер­ской экспериментального проектирования и планировки в деле реконструкции Москвы. Было установлено, что эта мастерская не только принимала деятельное участие в разработке проекта Юго-западного района в 1940-1941 годах, но и активно внедряла идею «микрорайона». В раз­работанных архитекторами мастерской проектных предло­жениях микрорайон рассматривался как группа кварталов, ограниченная магистральными улицами.

CdS Coated Mn Doped ZnO Nanospheres as Textile Catalyst: Fabrication, Physicochemical Techniques and Dye Removal Under Natural Light
Authors: Sivaranjani K , Sivakumar S , Dharmaraja J
Published: July 2022

ZnO as a promising photocatalyst has gained much attention for the removal of organic pollutants from water. However, the main drawbacks of the relatively low photocatalytic activity and high recombination rate of photo excited electronhole pairs, restrict its potential applications. Promoting the spatial separation of photo excited charge carriers is of paramount signi? cance for photocatalysis, because the dierence in the band positions make the potential gradient at the composite boundary. In this work, our aim is to enhance the photocatalytic efficiency of CdS coated Mn doped ZnO nanospheres under solar light irradiation. Objectives in this work are, to fabricate the CdS coated Mn doped ZnO nanospheres by a simple ethanolic dispersion method, and its applied for testing the photocatalytic activity of methylene blue (MB) dye. The fabricated binary composites were analyzed with different physicochemical techniques like PXRD, SEM with EDX, UV-DRS, PL and TEM. The photocatalytic degradation results have revealed that, the CdS coated Mn doped ZnO nanospheres exhibits admirable activity toward the photocatalytic degradation of the MB. The remarkably enhanced photocatalytic activity of CdS coated Mn doped ZnO nanospheres can be interpreted in terms of lots of active sites, which efficiently separate the photo generated electron and holes. A plausible mechanism is also elucidated via active species trapping experiments with various scavengers, which indicating that the photo generated O2 -and. OH radicals play a crucial role in photo degradation reactions under visible light irradiation. This work suggests that, the rational design and construction of heterostructures is powerful for developing highly efficient, and reusable visible-light photocatalysts for environmental purification and energy conversion. The enhanced photo degradation activity indicates the potential of the nanocomposite for the treatment of organic pollutants from the textile wastewater.

Asymptomatic bacteriuria (ASB) is the existence of bacteria in a patient's properly gathered urine who has no obvious symptoms of a urinary tract infection, which is common in females, with the prevalence rate of 2-11%, ASB during pregnancy is influenced by a range of factors including; mechanical compression, changes in the immune and renal systems, if ASB untreated, it can lead to cystitis and pyelonephritis. Our aim is to evaluate the sensitivity and specificity of the screening tests compared with the culture method for detection of ASB during pregnancy, and to identify the most common etiologic agents of ASB in pregnant women. An analytical cross- sectional study was carried out on 110 pregnant women, selected using nonprobability sampling methods their age between 18-45year- old with no signs and symptoms of urinary tract infections (UTIs). Clean-catch Midstream urine specimen from each participant was collected and submitted for routine analysis by dipstick to detect leukocyte esterase, nitrite reductase tests and microscopic examination to detect pyuria (pus cells), as well as urine culture, and biochemical test. About 14.5% of pregnant women were positive for ASB, the most prevalent bacterium Escherichia coli (37.5%) followed by Klebsiella pneumoniae (18.7%). There was no significant association between age, parity, gestation, recurrent urinary tract infections, Diabetes mellitus, hypertension and ASB. For screening tests; the nitrite test was more specific (98.9%) than leukocyte esterase and pus cells, on the other hand, pus cell detection was more sensitive (81.2%) than the other tests for detection of ASB. The prevalence of ASB was relatively high, no one used routine screening tests revealed both high sensitivity and specificity. So, urine culture remains the gold standard method for detection of ASB in pregnant women.

Published: July 2022

The main objective of the study is to find the effectiveness of sub occipital release technique in neck pain reduction, improving range of movement of neck and improving quality of life. Neck pain has a greater prevalence and is increasing globally because of various causes such as faulty posture, biomechanical causes in cervical, thoracic and scapular region. Tightness in the muscle leads to pain and decreased range of movements. This would reduce the performance of the person in day to day life and slowly will become partially dependent, and this has to be rectified in earlier stage itself. Even though, many research has been performed, they were performed only in the older age group, but not in adult age group. Variability in tension produces impact on structure and functions of cervical muscles. When there is an increased tension in cervical group of muscles, it produces imbalance in tone of the cervical muscles, which leads to neck pain and disturbed daily activities. There are various studies which had proved different methods of treatment involving various modalities, medications, exercises for treating nonspecific neck pain, but the effect of sub-occipital release technique is little understood and practiced. Hence an intervention with low time consuming and evidence based technique is needed. Sub occipital release technique helps to reduce tension in the muscles, thereby helping to perform daily activities effectively. This was an experimental study with pre-post test 20 samples selected from 30 volunteers based on the inclusion criteria. Group A is treated with sub-occipital release technique for 4 weeks, 3 days / week 2 sessions / day (Frequency: 3 times in one session). Control group performs isometric exercise for 4 weeks, 3 days / week 2 sessions / day (Frequency: 3 times in one session). At the end of 30 days of treatment session, there was a significant reduction of neck pain and increased range of motion of neck Flexion from 31.9 to 36.6, Extension from39.2 to45.0, side flexion from13.8 to 18.2, rotation from39.7 to 45.5(mean values), the mean values of VAS and NDI of pretest is 1.4 and 4.94; post test value is1.6 and 2.41.The result concluded that Group A who underwent sub-occipital release technique had more effective treatment in reducing pain and improving range of movements and functional abilities for non-specific neck pain.

This study was aimed to evaluate the serum IL-17A levels in chronic periodontitis patients with or without diabetes. The study was carried out in 168 subjects and consisted of 6 groups wherein group 1 consisted of 28 Type 1 diabetes patients with periodontitis, group 2 consisted of 28 Type 1 diabetes patients without periodontitis, group 3 consists of 28 Type 2 diabetes patients with periodontitis, group 4 consists of 28 Type 2 diabetes patients without periodontitis, group 5 consists of 28 Non-diabetic patients with chronic periodontitis, group 6 consists of 28 Non-diabetic patients without periodontitis (control group). The Sample of 3 ml venous blood was collected from cubital fossa of each subject and analyzed by using ELISA kit. Overall comparison of IL-17A level in between the groups showed that, there was a significant difference (p value < 0.001) among the groups with highest mean level (5.02±0.45) for group-3 (T2DM+CP) followed by group-5 (only CP) and lowest (1.21±0.49) in group-6 (healthy). The serum IL-17A is significantly high in chronic periodontitis and type 2 diabetes with chronic periodontitis.

Published: July 2022

The exhibition and business events industry has felt the negative impact of the COVID-19 pandemic most directly, as evidenced by the mass cancellations of business events, i.e., their transformation into virtual or hybrid forms. The paper analyses to what extent the pandemic has influenced all aspects of Croatian business events and the exhibition industry. It conveys the results of the Global Recovery Insights 2020 study undertaken by UFI, and the Global Association of the Exhibition Industry (hereinafter UFI) as well. Despite some weakening trends present in many countries and large markets, the industry is still a highly impactful one, particularly economically. To compare global occurrences and behaviour trends with the national practice, expectations, and future behaviour, we researched exhibitors at trade fairs in Croatia. The research results revealed that the crisis has accelerated the transformation of the exhibition and business events industry in terms of recognizing the benefits of digitalization, but also identified a paradox: reinforcing the desire and preference of exhibitors for live events. Socialization and the social aspect of networking, i.e., face-to-face meetings and communication remain an irreplaceable need, both for the exhibition and events industries in Croatia, which is analogous to global trends. Virtual, and especially hybrid events, have the potential to enhance user experience and attract a new, digitally native generation of users. Even though live events are still the first choice for exhibitors and sponsors, the hybrid mode is here to stay. Therefore, the global COVID-19 crisis emphasizes the need for redesign of the business event and exhibition industry business model, as well.

SHARIA CONTEMPLATION IN THE WORLD OF SUFISM: SYNERGIZING ACPECTS OF HAQIQA AND SHARIA IN THE SUFISTIC DIMENSION
Authors: Abitolkha Amir Maliki
Published: July 2022

This study aims to examine and analyze the concept of Shari’a contemplation in Sufism. It will show the importance of the synergy between Shari’a and Haqiqa dimensions in Sufism. This article is a literature-based study in which the data were collected from various literature, documentation, and other related sources. This study revealed that the concept of Shari’a contemplation in Sufism is a method of spiritual journey wherein someone practicing amaliah, teachings, and Sufistic life does not leave the commands of the Shari’a. The aspect of the Shari’a must be mature and still preserved with his intense closeness to Allah SWT. Contemplation of Shari›a as one of the spiritual practices emphasizes the importance of meditation and emptying the mind from everything except Allah SWT. Thus, a Salik is still obliged to carry out the Shari›a responsibilities and other obligations as a servant of Allah. In other words, contemplation is not limited to meditation physically but also inwardly, in the form of emptying everything except Allah and transforming ethical and aesthetic values into the practice of contemplation.
RECONCILING SCIENCE AND RELIGION BASED ON THE COMMON GOOD: REMEDY FOR ISLAMIC FUNDAMENTALISM AND PATH TOWARD DEMOCRACY
Authors: Hamida Aulia Shifa , Larasati Rahma , Putra Wibisana Sutan Akbar Kemal Syarief
Published: July 2022

Over the decades, there has been a growing understanding that emphasizes the separation between facts and values. Science is considered not to have the authority to answer questions related to morality. This article tries to offer a different argument emphasizing that science must have a role in answering various essential and urgent problems faced by many countries, namely, religious fundamentalism. This article offers a new synthesis of these relations based on the dialectical concept of two theories related to science and religion. Based on fiqh and the concept of maslahah, which have been the foundation for applying Islamic law, this article shows the positive relationship and the need for reconciliation between science and religion (Islam). Science turns out to offer an alternative solution, especially when there is the impossibility of separating religion and state. Reconciliation of science and religion (Islam) can contribute to the democratization process of Muslim countries without destroying Islamic religious values. The principle used is the concept of maslahah, whose focus orientation is for the common good.
The Confined Hydrogen Atom Ground State using a Compressed, not Truncated, Electron Probability Density
Authors: Carroll Kenneth
Published: July 2022

Since the pioneering works of Michels et. al., followed by Sommerfeld
and Welker, over eighty years ago, there is much interest in modelling
confinement of the ground state hydrogen atom by an impenetrable sphere
of confining radius, Rc. The literature “truncated probability
density” model assumes that, upon confinement, the nodeless free
hydrogen atom ground state probability density is replaced by the
innermost node of an excited state probability density, fitted to Rc by
a non-quantum parameter, λ. Since the literature model is an excited
state, the confined electron energy, E1c, is inversely proportional to
the excited state Bohr radius, Rλ (or aoλ2), which becomes larger than
Rc as λ increases. However, due to the infinite potential barrier at
radii greater than Rc, such large values of Rλ are not allowed. In
contrast, for the Particle in an Infinite Box (PIB), Harmonic Oscillator
(HO) and the proposed compressed probability density ground state
models, the particle energy is inversely proportional to the confined
length (Lc or Rc), the maximum length allowed. Additionally, the
Dirac/Sommerfeld fine structure formula calculation of E1c is in
agreement with the proposed model, but does not support the literature
truncated probability density model, indicating the literature model is
incorrect.
