Authors: Arifianto Muhammad Lukman , Izzudin Iqbal Fathi
Published: October 2021

Since the public release of Discord in May 2015, gamers have widely used it as an additional team speak application to communicate with their teammates while playing games. However, with substantial features, this application is also used as an alternative media of communication in teaching and learning activities. Therefore, this study aims to determine students’ acceptance of Discord as alternative teaching and learning media. Data were obtained using a simple questionnaire. Furthermore, their experience and acceptance towards this application are explored using the technology acceptance model (TAM) framework. The result showed that most participants confirmed that Discord is a favorable alternative media due to the attractive user interface, completeness of features, and its ease of use. Therefore, this application, which was originally intended for the gaming team-speak and team-chat experiences, can surprisingly be used as an alternative online learning media, especially during the Covid-19 pandemic, and it is well accepted by most students.

Adoption of Open Education Resources at a Higher Education Institution Using Explanatory Sequential Mixed Methods Research Design
Authors: Kandiero Agipah
Published: October 2021

The chapter is a walkthrough of a practical application of the explanatory sequential mixed method research design to investigate the adoption of open educational resources at a higher education institution in Zimbabwe. This is a complex phenomenon that required both quantitative measures to establish the nature and extent and precise qualitative explanations and justifications, an inherent precondition of mixed methods research. Justifiably explanatory sequential mixed method research was the appropriate research design to unpack the complex research problem due to its unique nature that permits flexible ontological, epistemological, philosophies, and analytical perspectives. The chapter illustrates how the quantitative component is complemented by the qualitative component to explain the complex phenomenon through integrated analysis and interpretation of research findings leading to valid conclusions and recommendations. In contribution to the development and use of explanatory sequential mixed methods research design, a new framework is proposed based on the lessons learned.

Background & objectives:

India witnessed a massive second surge of COVID-19 cases since March 2021 after a period of decline from September 2020. Data collected under the National Clinical Registry for COVID-19 (NCRC) were analysed to describe the differences in demographic and clinical features of COVID-19 patients recruited during these two successive waves.

Methods:

The NCRC, launched in September 2020, is an ongoing multicentre observational initiative, which provided the platform for the current investigation. Demographic, clinical, treatment and outcome data of hospitalized, confirmed COVID-19 patients were captured in an electronic data portal from 41 hospitals across India. Patients enrolled during September 1, 2020 to January 31, 2021 and February 1 to May 11, 2021 constituted participants of the two successive waves, respectively.

Results:

As on May 11, 2021, 18961 individuals were recruited in the registry, 12059 and 6903 reflecting in-patients from the first and second waves, respectively. Mean age of the patients was significantly lower in the second wave [48.7 (18.1) yr vs. 50.7 (18.0) yr, P<0.001] with higher proportion of patients in the younger age group intervals of <20, and 20-39 yr. Approximately 70 per cent of the admitted patients were ≥ 40 yr of age in both waves of the pandemic. The proportion of males were slightly lower in second wave as compared to the first [4400 (63.7%) vs. 7886 (65.4%), P=0.02]. Commonest presenting symptom was fever in both waves. In the second wave, a significantly higher proportion [2625 (48.6%) vs. 4420 (42.8%), P<0.003] complained of shortness of breath, developed ARDS [422(13%) vs. 880 (7.9%), P<0.001], required supplemental oxygen [1637 (50.3%) vs. 4771 (42.7%), P<0.001], and mechanical ventilation [260 (15.9%) vs. 530 (11.1%), P<0.001]. Mortality also significantly increased in the second wave [OR: 1.35 (95% CI: 1.19, 1.52)] in all age groups except in <20 yr.

Interpretation & conclusions:

The second wave of COVID-19 in India was slightly different in presentation than the first wave, with a younger demography, lesser comorbidities, and presentation with breathlessness in greater frequency.

Published: October 2021

Purpose This network meta-analysis (NMA) was conducted to compare the efficacy of immune checkpoint inhibitors in advanced non–small cell lung cancer (NSCLC) patients with liver metastases.Materials and Methods English literature was retrieved from the PubMed, American Society of Clinical Oncology, and European Society for Medical Oncology databases from January 2015 to January 2021. We pooled the overall survival (OS) and progression-free survival (PFS) hazard ratios (HRs) using an NMA and ranked treatments by the surface under the cumulative ranking curve. Publication bias was evaluated by Begg’s and Egger’s tests. STATA 15.0 was used for the sensitivity analysis, and the remaining statistical analyses were performed using R 4.0.2.Results Nine eligible phase III randomized controlled trials were included, including 1,141 patients with liver metastases. Pembrolizumab+chemotherapy ranked highest, followed by atezolizumab+bevacizumab+chemotherapy and nivolumab. However, no significant difference in OS rates was observed across these three treatments (HR, 0.98; 95% confidence interval [CI], 0.43 to 2.22 for pembrolizumab+chemotherapy vs. atezolizumab+bevacizumab+chemotherapy; HR, 0.91; 95% CI, 0.52 to 1.57 for pembrolizumab+chemotherapy vs. nivolumab). Regarding the PFS rate, atezolizumab+bevacizumab+chemotherapy and pembro-lizumab+chemotherapy ranked highest and no significant difference was observed between them (HR, 0.79; 95% CI, 0.36 to 1.70 for atezolizumab+bevacizumab+chemotherapy vs. pembrolizumab+chemotherapy).Conclusion Pembrolizumab+chemotherapy, atezolizumab+bevacizumab+chemotherapy, and nivolumab were superior to other treatments in NSCLC patients with liver metastases. These new findings may help clinicians better select therapeutic strategies for NSCLC patients with liver metastases.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) outbreaks in general hospitals are particularly risky because they not only overburden the regional healthcare delivery system, but also increase the possibility of community transmission. This study shares an experience of a COVID-19 outbreak response in a general hospital in Gyeonggi Province, Korea.METHODS: Since the first COVID-19 confirmed case was recognized in Hospital A on March 29, 2020, the Immediate Response Team of Gyeonggi Province and Korea Disease Control and Prevention Agency devised a plan to conduct an epidemiological investigation and minimize the paralysis of hospital functions. Apart from the epidemiological investigation, a risk assessment of the hospital and management of contacts, including patients and workers, were also undertaken.RESULTS: In total, 72 confirmed cases were identified, including 26 hospitalized patients, 16 healthcare personnel, 7 visitors, and 22 cases identified externally. The majority of the confirmed cases were exposed in Ward B or were contacts of people exposed in Ward A (58.3% of 72 cases). Among healthcare personnel, caregivers were found to be the most vulnerable to COVID-19 in this outbreak.CONCLUSIONS: Preparation for all possible situations in medical facilities is important because it is difficult to find alternative resources. The findings of this study provide information on controlling the further transmission of COVID-19 and furnish evidence of the importance of ordinary management skills to be prepared for COVID-19.

Authors: Simiyu Sheillah , Antwi-Agyei Prince , Adjei Kwaku , Kweyu Raphael
Published: October 2021

Sharing of sanitation is common in low-income settlements in Sub-Saharan Africa. However, shared (limited) sanitation facilities have been thought to pose health risks due to poor hygiene levels. Interventions to improve user behavior and cleanliness of shared sanitation are few, both in literature and in practice. This study details the codesign and testing of strategies to improve the cleanliness of shared sanitation facilities in low-income areas of Kisumu City in Kenya. The strategies included a cleaning plan, monitoring system, and discussions among users, and were codesigned through workshops with stakeholders and group discussions with landlords and tenants. These strategies were tested in 38 compound houses through the Trials of Improved Practices approach over a 5-month period. Field staff visited the compounds, observed the cleanliness of the shared toilets, and through discussions, encouraged users to develop a formal cleaning system and a monitoring plan. The discussions built social capital and collective action and facilitated uptake of the cleaning plan with notable improvements in cleanliness of shared toilets. The results support the acceptability of shared sanitation in low-income settlements, the importance of codesigning and coproducing solutions with users, and the need to evaluate the effects of these strategies on cleanliness of shared sanitation.

Published: October 2021

Rift Valley fever phlebovirus (RVFV) is a mosquito-transmitted phlebovirus (Family: Phenuiviridae, Order: Bunyavirales) causing severe neonatal mortality and abortion primarily in domestic ruminants. The susceptibility of young domestic swine to RVFV and this species’ role in geographic expansion and establishment of viral endemicity is unclear. Six commercially bred Landrace-cross piglets were inoculated subcutaneously with 105 plaque-forming units of RVFV ZH501 strain and two piglets received a sham inoculum. All animals were monitored for clinical signs, viremia, viral shedding, and antibody response for 14 days. Piglets did not develop evidence of clinical disease, become febrile, or experience decreased weight gain during the study period. A brief lymphopenia followed by progressive lymphocytosis was observed following inoculation in all piglets. Four piglets developed a brief viremia for 2 days post-inoculation and three of these had detectable virus in oronasal secretions three days post-inoculation. Primary inoculated piglets seroconverted and those that developed detectable viremias had the highest titers assessed by serum neutralization (1:64–1:256). Two viremic piglets had a lymphoplasmacytic encephalitis with glial nodules; RVFV was not detected by immunohistochemistry in these sections. While young piglets do not appear to readily develop clinical disease following RVFV infection, results suggest swine could be subclinically infected with RVFV.

We administered a standardized 41-item questionnaire to a convenience sample of graduates of five residency programs with formal global health pathways and compared findings to a national cohort of practicing physicians to evaluate the comparative effectiveness of an overarching global health pathway on residency program graduates. Compared with the national cohort database, global health pathway graduates self-reported that they felt better prepared to treat immigrants, refugees, patients with limited English proficiency (LEP), racial/ethnic minorities, those with non-Western health beliefs, international travelers, and military veterans (P < 0.05). They were more likely to report using best practices when working with lesbian, gay, bisexual, transgender, queer/questioning patients, immigrant and refugee patients, patients with non-Western health beliefs, patients with LEP, and patients communicating via American Sign Language (P < 0.05). They also reported being more familiar with 11 of 14 high-impact or common infections encountered in travelers, immigrants, and military personnel (P < 0.05). Our findings suggest that formal postgraduate training focused on global health improves knowledge, attitudes, and self-reported medical practices when caring for diverse and marginalized populations in the United States.

The paper provides a detailed overview of new radiocarbon dates, stable isotopes, and anthropological information obtained on prehistoric human remains (mostly Neolithic) from the Balkans and southwestern Carpathian Basin. It covers a large chronological sequence from the Mesolithic to the Bronze Age (9746–2628 cal BC), which encompasses different archaeological cultures. In total 76 radiocarbon dates deriving from 27 sites were obtained, coupled with new isotopic (n=34) and anthropological (n=33) data. The results filled the gaps in some of the older interpretations, but also produced new insights regarding chronology, health, and diet, leaving a strong baseline for all future research into Neolithic lifestyles.

Published: October 2021

The supply chain in the construction industry operates with many suppliers of the most varied technological and managerial characteristics. Integrating this diversity is a challenge. In this sense, studying the supplier in the supply chain can contribute to the industry's best results. This paper aims to highlight the research areas and relevant work on supply chain management in the construction industry, focusing on suppliers. Thus, a bibliometric analysis of citations and cocitation was performed with the support of the CiteSpace II tool. The raw data (publications limited to the period 1990 to 2019) were extracted from the Web of Science (WoS). Twenty research areas were identified, of which "integration" and "sustainability" were the most productive areas (most of the published works). The three most recent and promising areas were: "supplier selection", "sustainability" and "supply chain integration". As a final result, we present a panoramic map of the publications on the subject analyzed and how they are interconnected in networks (integration of works and formation of research areas). This map, among others, can instruct and mark future in-depth studies on a particular area of interest or how they relate to each other.

Published: October 2021

The current scenario of the construction sector has several peculiarities regarding the standardization and development of processes. These unusual features are not always favorable and resulting in rework and improvisations in the construction site, which leads to disruption of the process. One solution is to provide the complete kit, to avoid waste by making-do and work in progress. The aim is to identify which categories of best practice are most valued by engineers, in search of continuity of the work, by applying the complete kit. The method includes the elaboration of a framework of managerial actions; information about the importance of the adoption of best practices, through the application of questionnaires based in the theoretical framework. As a result, managers attributed "great importance" to the managerial actions of the categories: worker protection, work conference, process protection, and access. It is concluded that the managers concentrate on the work at the production site, rather than actions for work preparation, project and schedule.

In the Last Planner® System of Production Control, there are several indicators that are used to measure the efficiency of the technique according to the planning levels (long, medium and short terms), but treated in isolated ways. Typically, there is a lack of coherence, especially between medium and short-term plans. Thus, this study aims to broaden the discussion initiated in previous studies and propose a methodology to evaluate this adherence using indicators. The paper included the analysis of the Production Planning and Control model, and the medium and short-term plans of a residential project located in Natal/RN, resulting in various forms of lack of adherence between the plans, which can lead to wastes to the project's schedule and costs. The main contribution of the research is the improvement of the adherence indicators, in order to reflect the information in a more complete and comprehensive way.

Published: October 2021

Because the high subjectivity of value perception, besides the competitive environment of civil construction market, the focus on the external customer usually conflicts with the value to the organization’s internal customer. Thus, it is questioned who the different stakeholders in the construction chain are, and at what levels should have their view of value considered. As part of this process, this article aims to understand how stakeholders-builders have applied different management strategies in the crowded construction market. For this, semi-structured questionnaires were applied to managers of different companies, especially those with strategic decision-making powers. With this, a characterization of the management profiles was obtained, perceiving similar foci in the strategies of the companies, mainly in relation to the marketing for the external client and the internal innovation. It is concluded that, although there are clear focuses on business strategies, there is significant room for improvement in sectors such as technological innovations, people management and supplies.

Authors: Pérez Cristina Toca , Costa Dayana Bastos
Published: October 2021

The use of 4D Building Information Models (BIM) for planning construction site logistics has increased in recent years. However, most 4D BIM studies have focused on transformation tasks, neglecting flow activities. Hence, the objective of this paper is to evaluate the use of 4D models for flow simulation at operational level, aiming to reduce transportation waste. A field study was conducted on a residential housing project in Brazil. The study included three stages: data collection; 4D BIM simulation; and outcome analysis. Data collection during the site visits aimed to map the physical flows involved in the construction processes studied. Transportation waste were identified, constructive details were collected and time studies were conducted. This information was used for the 4D model development. During the outcome analysis the 4D BIM was presented and discussed in a seminar to the managers and in a workshop to the workers. After that, the model was implemented in the field and the contributions of the 4D BIM for transportation waste reduction were identified. The results highlighted the need to plan transportation activities in constructions site. The use of the simulation developed contributes to the reduction of transportation waste consequences, such as: unsafe working conditions, new transportation activities, and longer distances.

Published: October 2021

The construction sector has an important role in the global economy, but it is one of those that cause more environmental impacts. The sector has been concerned to sustainability issues and has used performance measurement and sustainability indicators to assist the environmental performance improvement. In Brazil, since 2012, the SIAC regulation of the Brazilian Program for Productivity and Quality of the Built Environment - PBQP-H started to require the collection of six sustainability indicators: waste generation throughout and at the end of the construction; water consumption throughout and at the end of the construction; energy consumption throughout and at the end of the construction. However, only the collection of the indicators do not generate performance improvement and reference values to guide the companies' goals. Furthermore, this paper refers to an on-going research which aims to establish a data base and benchmark values for the six PBQP-H sustainability indicators aiming to provide information for construction managers make decisions concerning the environmental quality performance of construction sites. The study was developed from a data survey conducted in seven Brazilian states. The main contributions of this study are the reference values presented for the indicators throughout the construction in each 10% of construction progress and the reference values presented for the indicators at the end of the construction.

Published: October 2021

Apesar de consolidados, os serviços tradicionais da construção precisam de inovação. Neste sentido, um caminho de solução para este impasse passa pela Construção 4.0, incorporando nas atividades da construção civil tecnologias como o BIM, Inteligência Artificial, Internet das Coisas, etc. O desconhecimento dos serviços oferecidos no contexto da Construção 4.0 dificulta a incorporação de tecnologias e características próprias da Indústria 4.0 nos serviços tradicionais. Consequentemente, neste artigo objetiva-se caracterizar aquilo que configura um serviço 4.0 na construção civil, a partir da análise de serviços associados a 15 tecnologias. A partir da revisão bibliográfica e documental, os dados foram coletados através de Websites de 148 empresas que oferecem serviços vinculados a tais tecnologias em diferentes países; e analisados, desagregando os serviços em seus componentes, ou subserviços, com relação à cadeia de valor do serviço. O resultado obtido foi o mapeamento dos componentes de 38 serviços associados àquelas tecnologias, mostrando que 38% dos subserviços são autônomos, enquanto 62% não são, além de mostrar que 65% dos componentes são associados ao ciclo de dados, enquanto 35% não são. Consequentemente, a interface humana é necessária para habilitar os serviços 4.0. Portanto, esta pesquisa contribui com a caracterização daquilo que configura um serviço 4.0 na construção civil.

Published: October 2021

Apesar da contribuição dos programas públicos de habitação na redução do déficit habitacional, as habitações populares geralmente falham em atender às necessidades dos usuários, além de apresentarem problemas construtivos e relacionados ao conforto. Esse cenário limita o desenvolvimento socioeconômico esperado, gerando custos adicionais aos usuários, como os relacionados à regularização, reformas e expansões. Este estudo faz parte de um projeto maior que visa a utilizar Living Labs (LLs) como abordagem para realização de processos de melhoria de habitações populares, ampliando a adequação das propostas às necessidades dos moradores. LLs são iniciativas de co-criação e de colaboração entre as partes interessadas (stakeholders), tendo o usuário como peça central para o desenvolvimento de soluções inovadoras. O objetivo deste artigo é apresentar o planejamento proposto e os resultados parciais obtidos no primeiro estudo de caso em um conjunto habitacional na cidade de Campinas. Detalhamos em específico a fase de compreensão do contexto local. Como resultado, este trabalho apresenta um modelo conceitual de uma implementação típica de um LL e contribui para a disseminação de iniciativas de fomento à inovação social em habitações de interesse social.

A Administração Pública investe alta quantidade de recursos para a contratação de projetos, obras e reformas, visando oferecer uma infraestrutura adequada para trabalho e bom atendimento à sociedade. Porém, é comum nessas obras a ocorrência de aditivos contratuais que podem trazer prejuízos à sociedade, causando desequilíbrio do orçamento esperado e prejudicando a visão do usuário final sobre as obras públicas. Neste sentido, o objetivo deste trabalho é levantar as causas de aditivos em contratos públicos, apresentar um panorama das falhas mais recorrentes e investigar soluções mitigadoras das causas levantadas. Para tanto, o método de pesquisa utilizado foi um Mapeamento Sistemático da Literatura. Como resultado, inadequações de projeto e deficiência no planejamento e/ou gerenciamento foram as principais falhas levantadas. As publicações que apresentam modelos ou métodos que propõem soluções para mitigar aditivos contratuais são discretas e recentes. Nota-se, ainda, que as soluções se concentram em questões de planejamento e/ou gerenciamento, havendo uma carência de pesquisas em áreas como a de projeto. A principal contribuição deste trabalho foi a identificação de uma lacuna de conhecimento em termos de pesquisas voltadas para soluções práticas e embasadas, visando a redução de aditivos contratuais de obras públicas e o consequente melhor aproveitamento dos recursos públicos.

A metodologia Building Information Modeling (BIM) tem se tornado essencial nos últimos anos para a indústria da Arquitetura, Engenharia e Construção (AEC). Dentre os seus principais usos aplicados à Construção Civil, a verificação automatizada de normas tem ganhado destaque na sua utilização, especialmente pelo fluxo de informações utilizados na metodologia. A redução de fatores como imprecisões de análises, tempo prolongado e interpretações pessoais tornam-se imprescindíveis para a garantia da qualidade do empreendimento, sobretudo na fase de projetos, onde o uso é aplicado. Considerando a sua importância, o presente artigo apresenta a aplicação da verificação automática a partir da metodologia RASE na Norma de Acessibilidade, a ABNT NBR 9050:2020. Além das recomendações da literatura, utilizou-se um modelo BIM, a fim de aplicar a programação visual, desenvolvidos em softwares específicos. Dentre os principais resultados destacam-se a aplicação da metodologia RASE na norma brasileira, o desenvolvimento da rotina de programação e a verificação automática, gerando resultados visuais diretamente no modelo. Além dos ganhos de tempo, redução de erros e melhoria na qualidade do projeto, a metodologia RASE, quando aplicada a este uso BIM, potencializa-o, tornando-o ainda mais acessível e aplicável à comunidade.

Devido à competitividade das empresas e a implantação de novas técnicas de gestão da indústria 4.0, a indústria da construção busca a implantação de novas soluções tecnológicas e procedimentos mais sustentáveis, social, ambiental e economicamente. Assim, as soluções tecnológicas em madeira ganham cada vez mais espaço e atraem um olhar otimista para o futuro. O alto índice de qualidade dos elementos de madeira pré-fabricados gera uma descentralização dos canteiros de obra, concentrando neles apenas a montagem das estruturas, e colaborando para a disseminação da construção off-site. Obtém-se uma redução de perdas, de mão-de-obra, de tempo de execução e, consequentemente, diminuição dos custos totais de obra. Logo, para sistematização das soluções existentes no mercado brasileiro, este trabalho teve por objetivo diagnosticar o atual cenário das construções em madeira no Brasil, a fim de identificar as soluções tecnológicas atuais. A metodologia empregada foi a de análise documental, por meio de pesquisa bibliográfica e, em seguida, foram identificadas as empresas que trabalham com os sistemas construtivos estudados. Pode-se concluir que, a madeira começa a recuperar a notoriedade de outros tempos, apoiada nas crescentes preocupações ambientais, nos avanços tecnológicos e nos estudos de suas características.

A integração entre Interface de Programação de Aplicativos (API) e a Modelagem da Informação da Construção (BIM) possui grande potencial para facilitar a quantificação de resíduos na construção civil desde a fase de projeto. Deste modo, observa-se a possibilidade de uso de APIs para produzir informações de grande relevância para o fomento da economia circular (EC) na indústria da construção civil. Esse artigo comparou dois APIs e avaliou seus potenciais de uso para fomento dos princípios da EC no setor. O método adotado foi o mapeamento sistemático da literatura seguido de análise comparativa de dois APIs identificados na etapa anterior. A principal similaridade entre as APIs encontra-se no fato de ambas terem sido desenvoldidas para o software Autodesk Revit. A principal diferença está no uso das APIs em distintas etapas do ciclo de vida da edificação. Os resultados sugerem a necessidade de estudos que estendam a integração de APIs a diferentes softwares BIM.

O atraso dos empreendimentos é uma das principais problemáticas do setor da construção civil, a análise de não-conformidades que ocasionam essa problemática, fornece às equipes tendências que podem ser usadas para desenvolver estratégias para evitar a recorrência das mesmas falhas no futuro. Desta forma, esta pesquisa se desenvolve com o intuito de avaliar a aplicação da análise de curto prazo do sistema Last Planner em obras residenciais e comerciais a partir da coleta de um banco de dados de 10 obras verticais de uma torre na construção civil, acompanhadas pela mesma empresa de consultoria em planejamento. Contabilizou-se as cinco causas mais frequentes, sendo a principal delas a mudança no plano de ataque da obra, e utilizando análise estatística observou-se que existe uma grande variabilidade do número de ocorrência das problemáticas ao longo das obras. Além disso, verificou-se que a grande maioria dos problemas são de origens internas, sendo planejamento e mão de obra os dois subgrupos com mais causas do não cumprimento de metas cadastradas. Concluiu-se que analisando as principais causas do não cumprimento das metas de curto prazo e identificando o seu comportamento é possível prever cenários e buscar melhoria contínua do projeto.

The incidence of the illness is too high in India as the cities here are exposed to some of the highest air pol-lution levels in the world. Added to this incidence of this illness, it may be crippling by virtue of its episod-ic, chronic course incapacitating the patient in his occupation. Moreover, as Acarya Caraka says the disease tend to incriminate the heart in the long run threatening one’s life. This illness is found to be mind boggling to the physician even. In spite of prescribing best available medicine, the complete cure proved impossible in many. Further, in some, managing the attacks seems to be difficult. In spite of weeping and wailing of the patients the physician’s sincere attempts tend to be vain. This is true for the conventional medicine and for any of the alternative medicine. Vata and Kapha are the two key pathological factors involved in the Samprapti of Tamaka Svasa demands distinct remedy and hence writing a prescription in such a situation is wheels in wheels. Dhumapana is one of the lines of treatment is explained in Caraka Samhita. Dhumap-ana has its own importance as the medicine is directly delivered into the Pranavaha Srotas and there by initiates rectification of morbidity. Thus, this comparative study planned to evaluate the therapeutic effect of Haridra Dhumapana and Svasakutara Rasa in patients suffering from Tamaka Svasa. Total 20 patients were included and treated with obsevertaion of 7 days under two groups (dhumapana group & Svasakutara ras grop). Finally, it was concluded that Dhumapana group comparatively better relief to the patients of Tamaka Svasa.
