Authors: Ahsan Behzad , Majedi Mohammad Azad , Sin Darreh Setayesh , Masaeli Milad
Published: November 2023

Background: Postoperative shivering (PS) is a mechanism to reduce heat loss and is the most frequent complication during the recovery period after general anesthesia. Shivering can lead to discomfort and is even risky in many patients; therefore, prevention is important. Objectives: Our study aims to determine the effect of dexmedetomidine on preventing shivering after general anesthesia in appendectomy patients. Methods: The present double–blind, randomized clinical trial divided 90 appendectomy patients into two groups. Randomization was performed using the www.random.org website from the numbers of sequence generator option. One group received 0.5 µg/kg of dexmedetomidine before induction of general anesthesia, and another group received normal saline as a placebo. Shivering and other outcomes were checked in both groups. To find a 50% reduction of this incidence, based on alpha error of 5% and beta error of 20%, the sample size of 45 people was determined for each group. A P-value ≤ 0.05 was considered statistically significant. Results: In total, 63 (70%) patients were male, and 27 (30%) were female. There were no significant differences between the two groups in terms of age (P = 0.412), weight (P = 0.460), temperature of serum for fluid therapy (P = 0.315), fluid volume (P = 0.736), perioperative body temperature (P = 0.418), preoperative body temperature (P = 0.540), and room temperature (P = 0.310). The severity of shivering was significantly lower in the dexmedetomidine group (60%) than in the placebo group (P < 0.001). There was no significant difference according to gender and severity of shivering between the two groups (P > 0.05). Conclusions: This study suggests that the administration of dexmedetomidine can prevent postoperative shivering.

Authors: Rizwan Muhammad , Naseem Sobia , Durrani Arjumand Iqbal
Published: November 2023

: The utilization of natural plants as potent sources for curing chronic diseases has increased researchers' attention toward herbal and nutraceutical treatments. Silymarin, a flavonolignan, is derived from the natural plant milk thistle, Silybum marianum. It is utilized in both clinical and experimental settings to protect against a variety of diseases. Silymarin has only a modest influence on the pharmacokinetics of numerous medicines in vivo. The pharmacokinetics of silymarin indicate that it is readily absorbed and metabolized in phases I and II. Its conjugation can be found in phase II, and it is ultimately eliminated in urine and bile. The main active ingredients, silibinin and silymarin, are protective against cancer in a wide range of tissues. Additionally, it exhibited anti-angiogenic, antioxidant, anti-inflammatory, and anti-metastatic effects. Several types of research have proven the chemopreventive effects of silymarin in both in vivo and in vitro models of tumor development. It could be used as an addition to existing treatments for cancer survivors. This review includes the chemistry of silymarin, mechanistic studies on the potential biological targets of silymarin/silibinin for chemoprevention, several putative molecular pathways, and human clinical trials.

Published: November 2023

Метою роботи є науковий аналіз інформативних можливостей статистичних підсумків загальних переписів населення як історичного джерела вивчення етносоціальних та етнокультурних процесів, визначення унікальності даних переписів населення як базового статистичного джерела для характеристики відповідних змін у структурі суспільства.Методологічну основу статті становлять принципи історизму, об’єктивності, багатофакторності і системності. Згідно з принципом історизму вивчаються основні тенденції формування програмних засад переписів населення, встановлюються їх взаємозв’язки із міжнародними методологічними зразками. Принцип об’єктивності сприяє виявленню можливостей статистичних підсумків переписів населення як комплексного джерела для вивчення окремих аспектів соціокультурних змін. Відповідно до принципу багатофакторності з’ясовано ступінь впливу об’єктивних та суб’єктивних причин на визначення пріоритетності програмних питань переписів щодо соціокультурних складових у різні історичні періоди. Застосування принципу системності дозволяє з’ясувати можливість розгляду соціокультурних характеристик населення в їх цілісності.Реалізація названих принципів здійснювалася за допомогою як загальнонаукових (аналізу і синтезу), так і історичних (проблемно-хронологічного, історико-порівняльного та ретроспективного) методів дослідження.Окрему увагу приділено характеристиці методологічних засад переписів населення у контексті теми дослідження. Зроблено наголос на важливості поєднання предметного аналізу статистичних даних опублікованих переписних видань та архівних відомостей переписів.До новизни наукової розвідки слід віднести здійснення аналізу підсумкових даних Всесоюзних переписів населення 1959–1989 рр. та Всеукраїнського перепису населення 2001 р. у поєднанні з раніше невідомими для широкого кола науковців архівними матеріалами як джерел для комплексного дослідження соціокультурних процесів в українському соціумі означеного періоду. При цьому важливою особливістю дослідження є приділення скрупульозної уваги до методології програмних документів загальних переписів населення та її зв’язку з міжнародними зразками переписної справи.Висновки. У підсумку необхідно зазначити, що всебічне та достовірне наукове осмислення етнокультурних та соціокультурних процесів можливе тільки за умови залучення до предметного аналізу статистичних даних таких широкомасштабних демографічних обстежень, як загальні переписи населення. Поєднання статистичної характеристики соціокультурних змін у соціумі з вивченням архівної інформації щодо етнокультурної та соціокультурної державної політики на різних історичних етапах спрямоване на повну реалізацію поставлених у статті дослідницьких завдань.

Authors: Huynh Thi My Duyen , Nguyen Thanh Sil , Ta Kien Tuong , Le Thi Minh Ngoc
Published: November 2023

Background: previous studies have demonstrated that Houttuynia cordata Thumb (Saururaceae), Morus alba L. (Moraceae), and Carica papaya L. (Caricaceae) are effective against various viruses, especially the SARS-CoV-2 virus. In Vietnam, even though the three of these plant species are grown quite popularly and are pretty commonly consumed by residents regularly, there have not been any applications to the dosage forms to promote their full potential effects and make these dosage forms easy to use and preserve. Furthermore, no research has been conducted on a capsule form that combines all three of these medicinal herbs. Objectives: the research focuses on the composition of a hard capsule formula containing the extracts of Houttuynia cordata, Morus alba, and Carica papaya as well as the development of testing standards for prepared hard capsules. Materials and methods: the ratio of adsorbents and fillers in the formula was investigated so that the granules had low moisture, a suitable flow rate, and the appropriate apparent density for packaging; standards for testing capsules were developed according to current regulations. Results: the selected adsorbent was light MgCO3, with a ratio of plant extract: filler: adsorbent of 10: 5: 0.5 and a ratio of Avicel: Starch 1500 of 1: 3. Conclusions: a hard capsule containing medicinal plant extract was formulated with a moisture content of < 5% and well-flowing granules that had the suitable apparent density for packing the capsule size of 0. Capsules met standards in terms of appearance, weight uniformity, disintegration, heavy metal and microorganisms, with a quercetin content of 74.45 ± 0.23 mg. The result of the study is considered one of the most essential bases for further research on determining the effectiveness of medicines derived from medicinal plants and applied to support the treatment of COVID-19, which is still happening in a quite complicated way at the moment.

Published: November 2023

Game theory, an interdisciplinary field that explores interactions among entities in strategic scenarios, is paramount for understanding how individuals make decisions in interactive situations. This paper outlines the development and evaluation of a playful exercise to facilitate understanding fundamental concepts such as dominant and dominated strategies and Nash equilibrium, employing a 'design thinking' methodology. An empirical evaluation was conducted with 76 Industrial Engineering students from the Universidad Industrial de Santander, dividing them into four teams representing companies vying for customers. The teams assessed payoff matrices and made marketing decisions, utilizing a colored die to eliminate non-advantageous strategies. Findings indicate a significant increase in interest in game theory, with 86% of participants expressing a preference for this method compared to conventional classes. Furthermore, 81% desired to incorporate this activity into their regular courses, while 76% applied previous knowledge during the training. An average improvement of 17% in correct responses suggests that the playful exercise effectively facilitates the assimilation of key concepts in game theory among university students. This study underscores the potential of integrating active activities based on game theory to enrich the learning process in an academic context.

Published: November 2023

Inventory Routing Problem is a critical component of Supply Chain Management, where it is a coordination of inventory management and transportation. It aims to balance the trade-off between transportation costs for delivering products and holding costs for maintaining inventory. Several real-world problems faced nowadays require effective optimization and logistical solutions, where this problem arises in various industries and has become increasingly complex.  The problem addressed in this study is based on an automotive parts supply chain that consists of a depot, an assembly plant, a set of homogeneous capacitated vehicles, and multi-suppliers on a finite horizon with multi-periods. Artificial Bee Colony is a swarm intelligence algorithm that is based on the behaviour of bees in a colony, where information is shared through waggle dance. ABC consists of three phases, which are employed bee phase, onlooker bee phase, and scout bee phase. This study proposed an enhancement in the initialization phase and in onlooker bee phase of the ABC algorithm. Clarke Wright savings algorithm was implemented in the initialization phase to determine the best feasible delivery routes while minimizing the total transportation cost. 2-opt and 2-opt(asterisk) were used to improve the routes in the onlooker bee phase. Results showed that 7 better total cost were found out of 14 benchmark datasets when compared to the previous literature. The enhanced ABC algorithm obtained better results with 5.59 percent at most, which demonstrated the effectiveness of the algorithm.

The Kom el-Hisn Provincialism Project (KHPP) began new excavations at the site of Kom el-Hisn, Baheira governorate in 2016. Our work specifically targets the Old–Middle Kingdom settlement remains with the aim of studying the activities and population of the site’s late third/early second millennium inhabitants from a local, bottom-up perspective. Previous understandings of the kom have interpreted it as part of a centralized government system. Indeed, authority and personal agency in the provinces is a subject of much recent discussion; discussion to which the excavations at KHPP aim in the long term to contribute. To date, limited new exposure at the site has extended our knowledge of the site’s date, differential settlement zones, and introduced new methodologies for object analysis.

Mass appraisal: a statistical approach to determining the impact of a property’s attributes on its value
Authors: Gdakowicz Anna , Putek-Szeląg Ewa
Published: November 2023

One of the problems occurring when estimating the value of a property is determining how the individual attributes of a property affect its value. Until now, this was estimated either on the basis of analyses of prices and market features of similar properties, or by analogy to other properties in terms of the type and area of markets, by examining or observing the preferences of potential buyers, or in other ways (Polska Federacja Stowarzyszeń Rzeczoznawców Majątkowych, 2008). This article refers to the last option and presents an alternative way of dealing with the aforementioned issue. An approach based on statistical methods, using dependency coefficients is introduced as an objective proposal to determine the impact of individual attributes on the value of real estate. The idea of including statistical methods (dependency coefficients) in the procedure of mass real estate valuation is the basis of the statistical approach of the Szczecin Mass Real Estate Valuation Algorithm (Pol. Szczeciński Algorytm Masowej Wyceny Nieruchomości – SAMWN). Considering the specificity of the features (attributes) describing real estate, which in most cases may be presented on an ordinal scale, four coefficients measuring the strength of the relationship between the features and the value of the property were proposed. Since previous studies, e.g. Dmytrów et al. (2020), indicated that the results obtained for partial coefficients reflect the relationships found on the market more efficiently, the analysis was extended to include partial variants of selected coefficients. Then, six procedures for calculating weights in SAMWN were proposed. The obtained results were subsequently ordered on the basis of linear ordering procedures, as described in the work by Strahl (1978) and Pawlukowicz (2010). The aim of the article was twofold. Firstly, to identify the coefficients of dependencies that can be used in property valuation based on SAMWN, and also in the analysis of those properties whose attributes are often described on an ordinal scale. The second aim was to identify a combination of methods describing the influence and weights of the attributes which under SAMWN procedure produces results closest to the property values determined by real estate appraisers.
COMPARATIVE FINANCIAL ANALYSIS OF FRUIT AND VEGETABLE JUICE PRODUCTION SECTORS IN SERBIA AND CROATIA
Authors: Mihailović Nenad , Radovanović Željko , Radovanović Sanja
Published: November 2023

The paper analyzes fruit and vegetable juice production sectors in Serbia and Croatia, with a special emphasis on the analysis of financial performance indicators. Costeffectiveness, profitability and liquidity indicators over the five-year period have been calculated on the basis of financial data. The aim of the paper is to examine whether there is a statistically significant difference between these indicators in the sectors of the two countries. Having in view that previous research results indicate a lower level of technical effectiveness of Serbian agriculture compared to EU countries, the paper examines the potential of the processing sector in generating new value and the possibility of creating a new product from primary agricultural products with considerably better business results. Based on the statistically significant difference in the mean values of financial indicators, the conclusion is that this sector in Serbia is more liquid and profitable than the counterpart sector in Croatia.

Risk language barriers in a globalized world: Insights from female managers from Slovenia
Authors: Tomec Tina , Gričar Sergej
Published: November 2023

Background: In today's interconnected and globalised business environment, effective risk management is essential for organisations to achieve sustainable success. However, communication and understanding risks across cultural and linguistic boundaries pose significant challenges. This paper explores the concept of risk language barriers and their impact on corporate management and performance. Purpose: This research examines the causes, consequences, and potential solutions to overcome risk language barriers in a globalised world. By shedding light on the importance of effective risk communication in a diverse and interconnected business environment, the study seeks to provide insights into the significance of addressing these barriers for successful management outcomes. Study design/methodology/approach: The study conducted in Novo Mesto, Slovenia, in February 2023 uses data from in-depth interviews and a focus group to investigate risk language barriers. The participants are women entrepreneurs with prior experience in cross-cultural communication and managing people in different countries, e.g. a Slovenian sales guru with a penchant for transcending borders and a Maltese digital strategist who, through global collaboration and expertise, ensures that every corner of the Slovenian organisation aligns with its overarching goals. Their experiences explore the challenges of risk language and the need for intercultural communication skills. Findings/conclusions: The research findings indicate that addressing risk language barriers is a strategic imperative for achieving successful management outcomes in a globalised business landscape. Overcoming these barriers requires a collaborative and proactive approach to risk communication. Developing intercultural communication skills allows individuals to navigate diverse environments effectively, provides them with more excellent networking opportunities, broadens their horizons, and fosters personal development. Furthermore, managers can strengthen relationships with clients and partners worldwide by addressing risk language barriers effectively. Limitations/future research: The study has limitations regarding its focus on women entrepreneurs. Future research should include diverse demographics and industries, conduct quantitative analyses, and explore technology's role in bridging the risk language gap and associated challenges.
Architectural spatial design strategies for summer microclimate control in buildings
Authors: Du Xiaoyu , Bokel Regina , van den Dobbelsteen Andy
Published: November 2023

The objective of this paper is to clarify the spatial design strategies used to control the microclimate of a Chinese vernacular house in summer by comparing the building with modern Chinese rural houses and presenting ideas for contemporary architectural design practice. For this goal the spatial configuration, the spatial boundary conditions, the vegetation in the space and the human activity in the space were analysed for the vernacular house and for modern rural houses. Also, field measurements were conducted to evaluate the summer thermal environment in the vernacular and a modern house. The results show that the vernacular house has a diverse spatial design and a better building microclimate, making it easier to obtain thermal comfort than the modern houses. Therefore, spatial design strategies of Chinese vernacular houses are still of great value to modern house design, especially when the free-running thermal comfort theory is applied.
Urban Form and Greenhouse Gas Emissions
Authors: Mehaffy Michael West
Published: November 2023

The research reported in this dissertation contains three complementary and overlapping parts:

One, “findings”: It assesses the factors of urban morphology that contribute to increased rates of greenhouse gas emissions per capita, and the ways they interact. It finds a significant but underrepresented set of factors, distinct from but relating the factors at the individual building scale and the scale of regional transportation systems.

Two, “strategies”: It assesses the methodologies by which such findings might be put to use in identifying and achieving reductions through changes in urban design, and proposes new strategies to do so using innovative forms of design decision support tools.

Three, “design decision support tools”: It then proposes a specific new technology, namely a new class of open-source scenario-modelling tool, embodied in new prototype software. The tool utilizes a new kind of “federated” web-based wiki technology incorporating design pattern languages, which was developed in collaboration with the software engineer and wiki inventor Ward Cunningham.

As part of this research, it has been necessary to examine fundamental methodological questions, and to account for limitations of current data as well as current significant gaps in research. In the process, this research has made a modest contribution to the state of knowledge about additional research needed.

For me, this work has also highlighted the need for urgent and effective reforms to current “business as usual” practices. The need is all the more urgent given unprecedented rates of urbanisation – much of it sprawling and resource-inefficient – taking place in many parts of the world today.
Harde stad, zachte stad
Authors: Reinders Leeke
Published: November 2023

There is something irrevocable in architecture. In contrast with a painting or a musical play, one cannot alter an architectural work of art other than by blowing it up or pulling it down. Streets, buildings, squares and parks are part of the hard, physical environment in which we organize our lives. But why conceptualize architecture as a finished product? What happens when the plans have been drawn, the buildings completed, the public space decorated and the pictures taken for design journals and marketing advertisements? How does the ‘hard’ city of architecture and urban planning relate to the ‘soft’ city of residents and users? How do people appropriate the planned city and make it their home? The thesis ‘Hard city, soft city’ is an anthropological study on the role of images and symbolic representations in the social production of urban space in Nieuwland, a post-war neighborhood of Schiedam, which is undergoing a process of large-scale restructuring. A central theme of the book is the intersection between planned and lived space. That is, between the city as object of planning and policy and as an object of everyday identity formation. The architecture and urban structure of post-war neighborhoods have been subject of numerous publications, but it is striking how little we know about everyday life that has unfolded in the years after completion. The book sets out to approach urban space not only from a physical and architectural point of view, but also as a social and cultural domain which is claimed by various groups and institutions. This is examined through the images, symbols and stories used by professionals and residents to give form, meaning and substance to urban space, such as in branding and narrative cartography. Using the philosophical work of Michel de Certeau and Henri Lefebvre, the book examines how an anthropology of urban space contributes to our knowledge on the city, as a political object of policy, architecture and planning and as an everyday living environment.
Evaluating a self-proclaimed successful Dutch supply chain partnership
Authors: Venselaar Marieke
Published: November 2023

This study aims to reflect on experiences of professionals from a Dutch housing association and a contractor who perceive their relation as a successful supply chain partnership (SCP). Employing a narrative approach, this study shows the subgrouping in informal relations within and around the successful supply chain. The subgrouping shows examples of visible and hidden power dynamics. We conclude that, although the perception of success may have positive spin-offs, the members are not always positive about each other, SCP is applied to only a limited part of the client’s internal supply chain, SCP is applied in an arbitrary way that not always seems to be fair, and continuation of the success in the future is uncertain. The study provokes many practical interventions, but the main recommendation is to keep reflecting on informal relations to address some of the social issues.
Conclusions
Authors: Venselaar Marieke
Published: November 2023

This research aimed to describe work floor experiences of project leaders who work for Dutch housing associations and who attempt to apply principles of SCP. Reason to do this, was that current research about SCP does not provide insight in what goes on at the work floor. This insight is necessary, because supply chain partnering is formed by ongoing complex responsive processes of interaction between professionals in their daily work life. To intervene effectively and to improve performances of collaboration, work floor experiences were studied. This research consists of a literature review, three case studies, and an overarching study in which the insights that are gained in the three case studies are synthesized.
