The Impacts of Career-Related HRM Practices on Project Worker Positive Attitude Toward Organizational Change
Authors: Johnson Nathan , Fan Yang , Li Yanju
Published: July 2022

This study investigates the relationship between a project worker’s attitude toward organizational change and the organization’s career-related human resources management (HRM) practices. A quantitative research study utilizing survey data collected in China was conducted with project workers in the oil and gas industry. A hierarchical regression model was used to identify how HRM practices impact employee positive attitudes toward organizational change (PATOC). Study results indicate that professional development programs are not statistically significant predictors of project worker PATOC. The results also show that internal promotion opportunities can significantly predict a project professional’s PATOC. Findings suggest that project management contextual influences may limit the efficacy of some HRM practices.
Technology valuation for intellectual property commercialization
Authors:   Division of Convergence Business, Korea University, Seoul, South Korea, Kim Heung Su
Published: July 2022

This study was conducted to evaluate the technical value of 19 intellectual property rights held by the Korea Research Institute of Bioscience and Biotechnology, and the purpose of this valuation is to promote commercialization by acquiring the technology transfer or exclusive license for the intellectual property rights. This study examines the theoretical and practical aspects of the valuation methods and procedures of the income approach that are useful for valuing intellectual property. Assuming that bioscience and biotechnology firms receive license transfer of intellectual property held by a foreign company, the valuation analysis of intellectual property based on the profit approach is based on business plans and financial statements of domestic companies. After calculating the operating profit from the gross profit of the company in detail, the corporation tax and the capital cost are taken into account and the depreciation cost is increased or decreased to calculate the excess profit and multiply the present value by the present value. We propose an income approach model and a case analysis to obtain the ultimate value of intellectual property by multiplying the contribution by this factor. It is not easy to predict future cash flows and estimate various financial statements, and there is a limit to the possibility that the evaluator will be subject to the estimation of the appropriate discount rate. More detailed and partial complementary research classified by the industry size is to be left as a future study.

Published: July 2022

La producción de leche en sistemas ganaderos del trópico alto colombiano es muy importante, ya que constituye una actividad económica que involucra a cerca de cien mil unidades productivas. Dichos sistemas de producción cuentan con una oferta nutricional basada en gramíneas como el kikuyo, raigrases mejorados y leguminosas como los tréboles. Sin embargo, la oferta de forraje en estas zonas se ve seriamente perjudicada por la variabilidad climática y por el deficiente manejo agronómico de las praderas. Dado que el forraje es el alimento más económico para alimentar a los bovinos, las estrategias para propiciar sistemas de alimentación eficientes y sostenibles basados en forrajes contribuyen a promover la seguridad alimentaria, la calidad de vida y la resiliencia de las comunidades. En este manual, se presentan alternativas para mejorar integralmente los sistemas de alimentación bovina del trópico de altura, tomando como base las condiciones y experiencias del trópico altoandino de Nariño.

Authors: Kocol Dilara , Bäuerle Alexander , Schadendorf Theresa , Moradian Sheila , Krakowczyk Julia Barbara , Skoda Eva-Maria , Teufel Martin
Published: July 2022

BACKGROUND

Obesity and depression are inter-related health concerns, demanding a high level of treatment and costs in the health care system. The development of eHealth interventions that simultaneously address obesity and mental health can be supportive in this regard. However, evidence of the efficacy of eHealth interventions in the treatment of depression in obese people is lacking.

OBJECTIVE

The aim of this systematic literature review is to evaluate the efficacy of existing eHealth interventions for obese people that target depression.

METHODS

We systematically searched electronic databases (Cochrane Library, PubMed, Scopus) to identify studies published in English between January 2016 and December 2021, that focused on eHealth interventions, targeting depression in obese people. Exclusion criteria were study objectives that (1) focused specifically on one or more metabolic comorbidities of obese people, e.g., hypertension, hyperlipidemia, diabetes; (2) focused specifically on eating disorders comorbidities e.g., binge eating disorder, and (3) focused specifically on patients before or after bariatric surgery.

RESULTS

The database search identified 187 records. Six articles were included in this review. Sample sizes ranged from 70 to 1267 participants of ages 18-60 years. All included studies were randomized controlled trials. Two of the six included studies were web-based interventions guided either by medical doctors or psychologists. All interventions included video, printed materials, and interactive parts of which two studies integrated elements of Cognitive Behavioural Therapy and Social Cognitive Therapy. The findings showed that eHealth treatment services, supported and guided throughout the intervention had high acceptance and efficacy in the reduction of depression among obese people.

CONCLUSIONS

EHealth interventions that address and target both mental and physical health with interactive strategies calls for better efficacy in the reduction of depression. Future eHealth interventions that target depression in obese people should integrate digital strategies that address both mental and physical health through interactive modules.

Arab Journal of Plant Protection, 40(2): 188-192. https://doi.org/10.22268/AJPP-040.2.188192 This study illustrates the acute toxic effect of ash released from Durah power plant (DPP) on the biology of the phytoplankton species Chlorococcum humicola in Iraq. The results showed that the median lethal concentration for killing 50% of the Alga population (LC50) was 0.15 and 0.13 ppt (parts per thousand) for 24 and 48 hours exposure to crude ash concentrations, respectively. In contrast, no LC50 value was recorded for 72 and 96 hrs after exposure. The reduction in the optical density absorption value and the growth rate recorded was 0.083±0.121 cells for the highest ash concentration used, compared with 0.594±0.099 cells recorded for the control group. On the other hand, the doubling time for the control group was 1.16±0.652 an hour compared with 1.36±0.981 an hour recorded for 2 ppt ash exposure. The current study confirms that the crude ash concentrations tested had an adverse toxic effect on the biological parameters of the algal species Chlorococcum humicola in Iraq.

О балансе между сохранением и модернизацией архитектурно-градостроительного наследия
Authors: Бондаренко Игорь
Published: July 2022

До сих пор не вполне ясны причины возникновения острой конфликтной ситуации между защитниками архитек­турного наследия и сторонниками модернизации городов. И те и другие апеллируют к историческому опыту. Действи­тельно, была традиция поддержания преемственности, но известна и другая традиция, согласно которой уничтожать старое и создавать на его месте новое считалось делом нуж­ным и прогрессивным. Возникает парадоксальный вывод о том, что охрана наследия требует разрушения одного из устоев традиционной культуры. В данной статье предлагается рассматривать обозначенную проблему, исходя из призна­ния исторически беспрецедентной новизны сложившейся культурной парадигмы. Анализ отношения к сбережению и обновлению старых построек и планировок в исторической ретроспективе приводит автора к заключению о том, что в Новое и Новейшее время новаторские устремления стали чрезмерными, агрессивными, сокрушительно-революци­онными. Сегодня настало время отказа от радикального обновления исторического наследия, признанного невоз­обновляемым культурным ресурсом. Архитектурные новации обязаны быть априори деликатными по отношению к нему и иметь пространственную обособленность. Только при таком условии становится возможным возвращение к умеренной, естественной и жизнеспособной концепции устойчивого, бесконфликтного развития среды жизнедеятельности.

Published: July 2022

Respiratory tract infections (RTI) are a major cause of mortality and morbidity in children. Several studies have aim supplementation as a possible preventive measure against respiratory tract infections in children. Vitamin-D (sunshine vitamin) is a type of prohormone with various functions like extracellular calcium ion maintenance, immunomodulation in the body. The three major sources of Vitamin-D are Sun exposure, Diet and Supplements. The main objective of our study was to correlate the vitamin D deficiency in children with RTI’s. A prospective observational study was conducted for 6 months inpatient of the Pediatric department in tertiary care hospital. Demographic details, cause of admission, past medical and medication history, feeding history, sun exposure was taken by interviewing the guardian. Data of a total of 25 pediatric patients with various respiratory tract infection cases were collected, documented and their vitamin D levels were analyzed in our study. The vitamin D level of samples was analyzed by Electro chemiluminescence immunoassay. Statistical methods were applied and significant differences were observed among the vitamin D sufficient and deficient patients with RTI’s. It was observed that out of 25 cases, 16 cases had recurrent respiratory tract infections and 9 had non-recurrent respiratory tract infections which statistically shows P value < 0.05. This study significantly correlates vitamin D deficiency with respiratory tract infections in children. This study also suggests vitamin D as a supplement therapy as it plays an important role in the innate and the adaptive immunity.

Published: July 2022

One precancerous condition with a high potential to turn into malignancy and pose a high risk is OSMF (oral submucous fibrosis) which mainly affects the young subjects globally as well as in India. The etiology of OSMF is attributed to the gutkha chewing habit. Another predominant etiologic factor governing the etiopathogenesis of malignant and premalignant lesions is the Candida species. Our aim of the present clinical study was conducted to assess and compare the intensity and incidence of Candida species in healthy subjects and subjects with oral submucous fibrosis. This study included 24 healthy controls and 24 subjects with a confirmed diagnosis of OSMF. A detailed history was recorded and a clinical examination was done for all the study subjects. All the samples were obtained from the oral rinse and were cultured using Sabouraud’s agar medium followed by identification and counting of isolated yeast species on sugar assimilation test, chlamydospore formation, and germ tube test. In the OSMF group, Candida species were isolated from 41.66% (n=10) of subjects. However, in the control group, Candida species were isolated from 16.66% (n=4) of the collected samples. This identification difference showed that higher species were isolated from the OSMF group compared to the control group (p=0.07). In the OSMF group, CFU/ml had a range of 500-970 with mean CFU values of 721.27±143.88. In the control group, the CFU/ml range was 60-320, whereas, the mean CFU/ml value was 186.64±130.10. The mean value was higher in the OSMF group compared to the control group. This difference was statistically significant with a p-value of 0.005. The present study concludes that the intensity and incidence of C. Albicans, candida species was higher in subjects with OSMF compared to healthy controls, however, these species were in the normal range of 3% to 47%. Hence, Candida cannot be considered an etiologic factor for transforming OSMF into a malignant lesion. However, further evaluation is needed to evaluate if betel quid chewing in subjects with OSMF promotes or inhibits the invasion and adherence of Candida species.

Authors: K Sumathi , B Manthra , Lalitha Shenbaga , Chandrika Mary , Sridevi Chaganti
Published: July 2022

C-reactive protein (CRP) is a protein produced by the liver. CRP levels in the blood, rises when there is an inflammatory condition in the body. A CRP test determines the amount of CRP in the blood to detect inflammation caused by acute conditions or to monitor disease severity in chronic conditions. Covid – 19 is an inflammatory condition, and an increase in CRP level helps in assessing the severity of covid illness. Our aim is to compare the severity of covid illness between the vaccinated and non-vaccinated individuals by estimating the CRP level. This is a cross-sectional study that included 100 Covid positive patients who were clinically diagnosed with fever at Sree Balaji Medical College and Hospital and were randomly selected (both vaccinated and unvaccinated) for the study. The level of serum C-Reactive Protein was estimated in all covid positive patients using the latex agglutination method. Of the 100 covid positive patients, 30 were vaccinated and 70 were not, with 8 vaccinated and 63 non-vaccinated individuals hospitalized due to increased severity. Only 27% of vaccinated people had elevated CRP levels, whereas up to 90% of non-vaccinated people had elevated CRP levels, emphasizing the importance of vaccination in reducing the severity of covid-19 infection. From this study, it was concluded that it is mandatory to estimate CRP level in covid- 19 patients as it is an inflammatory marker to assess the severity of the infection in them. Consequently, it is found that vaccines play an important role in reducing the severity of covid infection (as inflammation is reduced)

Authors: Abdolmalaki Parastoo , Koneri Raju
Published: July 2022

Monitoring utilization pattern of antimicrobial drugs for the treatment of UTIs can provide an important vision into a rational prescription of antimicrobials and prevent inappropriate therapeutic outcomes. This study aimed to focus on the study and analysis pattern of antimicrobial utilization in the management of UTI among patients admitted to a tertiary care hospital. A prospective study was conducted over six months in the Medicine Department of Bangalore Baptist Hospital, Bangalore, India. A total of 150 patients with UTI aged ≥ 18 years were included in the study, of which the majority of patients were female. A comorbidity analysis showed that forty-one (27.3%) patients had diabetes mellitus followed by hypertension (39, 26%), renal failure (23, 15.4%), renal calculi (17, 11.3%), and malaria (8, 5.3%). E. coli (23, 54.76%) was the most common isolated organism. Analysis of the utilization pattern of antimicrobial drug classes in patients with urinary tract infection revealed that cephalosporin (90, 60%) was the most-common prescribed class of antimicrobial drugs for management of UTI. Cefotaxime (47, 31.33%) was the most commonly prescribed cephalosporins. Fluoroquinolones (42, 28%) were the second most common pharmacologic class of antimicrobial drugs prescribed for the treatment of UTI of which ciprofloxacin (18, 12%) was the most commonly used fluoroquinolone. Overall, we identified 41 (Drug-Drug Interactions) DDIs between prescribed antimicrobial drugs and other medications. Interaction between ceftriaxone and calcium salts (13, 31.71%) was found to be the most commonly identified DDI. A periodic review of antimicrobial utilization patterns should be performed to enhance the empirical treatment of UTIs according to patients` urine culture reports. Our study findings provide feedback to prescribers to stimulate thinking about their practice and look for ways to improve rational antimicrobials prescription, and patient safety.

Published: July 2022

Appropriate project delivery method (PDM) is vital to ensure good performance of construction project. For decades, numerous researches have been conducted to develop a structured and descriptive decision-making framework for selecting an appropriate PDM. However, the adoption of structured and descriptive decision-making in selecting PDM in the construction industry is still understudied, especially in the Malaysian public sector. Thus, this paper attempts to investigate the practices and constraints of the Malaysian public sector in PDM selection for construction projects. This paper adopts an interpretive approach by conducting in-depth literature reviews of the numerous related researches, government policy and guidelines of PDM selection. This paper also assesses the effectiveness of the current PDM selection practices based on previous study findings and reports on PDM performance. Findings indicate that the traditional delivery method is prevalent PDM in most Malaysian public-funded construction projects. The Malaysian public sector has practised authoritarian and prescriptive decision-making governed by the government procurement guidelines in selecting PDM, which intentionally preserves political interests. Inappropriate PDM selection in project execution has produced an unconvincing performance by showing optimism bias on the expected outcome. The Malaysian public sector needs to improve the decision-making process by introducing a structured and descriptive PDM selection framework to derive better outcomes and convincing results. Thus, this paper is significant in improvising the decision-making mechanism in selecting appropriate PDM for the Malaysian public construction project.

Published: July 2022

Cost management practices have remained a vital aspect of project management functions. Despite the efforts of project management, construction projects are still being delivered above budget, with schedule overrun, poor quality and amongst other problems. Poor cost management approaches have been blamed for these problems. Effective cost management improves project performance and the strategic performance of construction organisations. This study aims to assess the role of cost management practice on construction firms' strategic performance in Nigeria. The objectives of the study are to determine the benefits of cost management of the project on the competitive position of construction firms, and the factors influencing cost management strategies of construction firms. This study adopted a well-structured questionnaire administered to construction professionals via electronic means and using snowball sampling technique in the six states of the south-south geopolitical zone of Nigeria. With a response rate of 65.48% and a reliability of index of over 0.70, the gathered data were analysed using frequency, percentage, and relative importance index (RII). It was found that major factors influencing construction cost management are; experience and competence of the project managers, weak management support and control, poor project communications, external economic environment, and lack of use of project management tools (technology). Also, effective cost management was found to play a critical role in the strategic performance of construction organisations; with most benefits being in the areas of waste and expenses reduction, improves operational efficiency need, helps to predict future expenses, ensures procurement effectiveness, and improve profit maximization. Project managers should continuously upgrade their skills for effective cost management to boost the strategic competitive position of their firms.

Authors: N Saka , F Adegbembo T
Published: July 2022

The construction sector makes significant contribution to employment, domestic capital formation and the Gross Domestic Product (GDP). However, the Nigerian Construction Sector (NCS) is beset by a number of challenges including over-dependent on foreign inputs, economic volatility, low linkages and poor project cost and time performance. The study investigates the impact of the construction sector on the GDP using a 47-year annualized Time Series Data (TSD) gotten from the United Nations Statistics Department (UNSD) database. The study employs econometric methodology which involves series of tests and procedures including tests for unit root and cointegration and Polynomial Distributed Lag (PDL) model. The summary of the estimates including the PDL indicate significant effect of the construction sector on the GDP only when the lag of the GDP is not included as one of the regressors. The study concludes that the effect of the construction sector on the GDP is not robust. Finally, the study recommends for a new national housing and transport infrastructure policy for the sustainable development of the Nigerian constructed infrastructure facilities. The study has demonstrated the relationship between the NCS and GDP. The study added to the body of knowledge by using time series data involving the use of distributed lag model (DLM), autoregressive distributed lag (ADL) model and polynomial distributed lag (PDL) model to assess the relationship.

Introducción: los gobiernos, las empresas y las personas han incrementado su preocupación por el aumento en las emisiones de gases de efecto invernadero, producido en su mayor parte por las actividades humanas. Para mitigar el impacto ambiental se han creado una serie de herramientas, objetivos, y acuerdos para su respectivo control. Una de las herramientas que se presenta para dar solución a esta problemática es la huella de carbono, ya que permite estimar las emisiones de CO2 generadas a la atmósfera a causa de actividades a nivel personal u organizacional. Objetivo: el objetivo del presente estudio es medir la huella de carbono corporativa en una Institución de Educación Superior; promover acciones correctivas en la optimización del uso de combustibles fósiles, el consumo de energía, el papel, entre otros que permitan mitigar su impacto; y generar unos lineamientos para que otras Instituciones de educación superior puedan realizar sus mediciones de Huella de carbono corporativa. Como eje fundamental de la formación, las Instituciones de Educación Superior deben ser entidades líderes en la realización de estrategias de sostenibilidad ambiental. Materiales y métodos: el presente estudio se desarrolla en una importante institución de educación superior colombiana, comprometida con el medio ambiente y su respectiva mitigación de gases de efecto invernadero, haciendo uso de la huella de carbono corporativa bajo los lineamientos de la norma ISO 14064-1/2006. Resultados: los resultados muestran que las fuentes de emisión clasificadas en los alcances 1, 2 y 3 generaron el 5,4 %, el 60,6 % y el 34,1 %, respectivamente de las emisiones totales. Conclusiones: el alcance 2, producto del uso de la energía, es el que mayor impacto genera, seguido del alcance 3, denominado como otras emisiones indirectas, que en este caso se generan por los viajes que realizan los empleados, en su mayoría el personal docente a congresos, estancias de investigación, entre otros. Finalmente, el alcance 1, tiene un impacto bajo en las emisiones totales.

Published: July 2022

Introduction: The SARS-CoV-2 is the denomination of the new betacoronavirus, which was discovered and isolated for the first time in Wuhan, China, at the end of December 2019, and it is the causal agent of the sanitary emergency of the COVID-19 pandemic. Experimental studies have shown susceptibility to infection in pets (dogs and cats). Objective: To present the current information available on SARS-CoV-2 in animals under the care of humans that have been officially reported in the sanitary registries of the World Animal Health Information System (WAHIS) of the World Organization for Animal Health. Materials and methods: We conducted a narrative review using Medline/ PubMed, Scopus, and Web of Sciences, and official documents of the World Organisation for Animal Health. The search terms used were as follows: “coronavirus”, “SARS coronavirus 2019”, “SARS-CoV”, “SARS-CoV-2 in dog and/or cat” “pets SARS-CoV-2”. Results: The studies reviewed in this manuscript highlight those positive cases in cats and dogs for SARS-CoV-2 have been associated with an exposure to positive COVID-19 people. In the available evidence, 55.17 % of the total cases of animals that were positive for SARS-CoV-2 were associated with people with COVID-19 who had the disease at home, possibly due to maintaining a longer exposure to the humans. Conclusion: Regarding the zoonotic aspects, it is important to clarify that although several animal species have been infected by SARSCoV- 2, none of them has been scientifically proven to represent a risk of direct transmission between positive animals and other humans or to play an epidemiological role in the disease.

A review on modeling of proton exchange membrane fuel cell
Authors: Hamdollahi Sahra , Jun Luo
Published: July 2022

Fuel cells are electrochemical devices that convert chemical energy into electrical energy. Among various fuel cells proton exchange membrane fuel cell (PEMFC) is considered one of the most promising candidates for the next generation power sources because of its high-power densities, zero-emission, and low operation temperature. In recent years, modeling has received enormous attention and interest in understanding and studying the PEMFC phenomena. This article reviews recent progress in PEMFC modeling. Empirical/semi-empirical, analytical, and mechanistic models, zero-to-three dimensional models, and multiphase flow models, such as multiphase mixture, multi-fluid, and VOF models, are different types of PEMFC modeling approaches, respectively, in terms of parametric, dimensional and two or three-phase flow. The present study enlightens the importance of combining different modeling strategies and parameter identification in PEMFC modeling to achieve precise models to reduce the time and cost of experiments.

Large-scale production is always associated with more and more development and interaction among peers, and many fields achieve higher economic benefits through project cooperation. However, project managers in the traditional centralized approach cannot rearrange their activities to cross-organizational project management. Thanks to its characteristics, the Blockchain can represent a valid solution to the problems mentioned above. In this article, we propose Fabric-GC, a Blockchain-based Gantt chart system. Fabric-GC enables to realize secure and effective cross-organizational cooperation for project management, providing access control to multiple parties for project visualization. Compared with other solutions, the proposed system is versatile, as it can be applied to project management in different fields and achieve effective and agile scheduling. Experimental results show that Fabric-GC achieves stable performance in large-scale request and processing distributed environments, where the data synchronization speed of the consortium chain reached four times faster than a public chain, achieving faster data consistency.
