Thermal comfort guidelines for production spaces within multi-storey garment factories located in Bangladesh

This research presents extensive field data on indoor thermal conditions along with workers' comfort votes taken at their workstations within three existing multi-storied garment factories during the three seasons (cool-dry, hot-dry and warm-humid) of Bangladesh. The main objective of the study was to observe the impact of thermal conditions on workers’ indoor thermal perception during each season of a year and from this identify thermal comfort guidelines (e.g. neutral temperatures, comfort ranges, preferred airspeeds and directions) to execute their production work comfortably. Subjective votes were collected from a total of 908 workers with the thermal data, physiological data and adaptive measures recorded simultaneously. Statistical analyses revealed that workers can accept a wider and relatively higher comfort range than the predicted band during cool-dry and hot-dry seasons, for instance, 22.7–29.1 °C and 22.3–30.4 °C respectively. A narrower comfort band (e.g. 28.7–30.9 °C), close to the predicted range, was found during the warm-humid season, which can be maintained by reducing radiant temperature and elevating airspeed. Further analyses indicated that workers prefer a mean airspeed of 0.3  m/s and comfort range of 0–3.0  m/s specific to their activities preferably from inlets located on south, north and east facades while upward and downward air movement, from for example ceiling fans, causes a rise of air temperature in the occupational zone and thermal discomfort. This research also suggested that the maximum distances of workstations from the ventilation inlets (windows) should be maintained at 12–18 m for sufficient cross ventilation, personal controls and adaptive opportunities to help maintain preferred thermal condition

A Case Report of Case Report Pursuit by Medical Student

Medical students often seek case reports as vehicles for academic writing opportunities, conference presentation avenues, and residency/fellowship application highlights. Here we review a case where, due to unfortunate circumstances, a student made a unique diagnosis central to proper patient clinical care, wished to write up the case subsequently, but was ultimately excluded from the final work stemming from the patient case. We review the pitfalls that occurred in the process of pursuing publication of an interesting case, the educational value of pursuing case reports for students, the necessity for strong mentorship in this process, and general principles that medical students can follow regarding case report creation to avoid being burned

Terrorism : a new threat for Indonesia? : an analysis on the national security of Indonesia in the post-Suharto period

Indonesia is the fourth most heavily populated nation in the world with over 210 million inhabitants. Almost half of all Southeast Asians live in Indonesia, and it is also the world’s most populated Muslim nation. These features make it a crucial country in the Southeast Asian Region, as well as in the world. Therefore, the national security of this country is very important to the region and the world. Security or national security covers dealing with the threat(s) to the state, so, in order to study this issue, we need to identify what kind of threat is behind the scenario. Indonesia’s post-independence political history has been dominated by two long serving presidents. During Sukarno’s period (1949-1965), external or conventional military threats ranked the highest priority in the agenda of national security; but after the fall of Sukarno in 1965, under Suharto’s New Order (1966-1998), the focus was changed to internal threats, such as secessionist movements, religious conflicts, radicalism and so on. The security goals of the New Order government were to maintain sovereignty, unity, integrity and stability though economic development and military suppression. However, in May 1998, anti-government demonstrations (Reformasi Movement) make Suharto step down. Within 2 years, the presidency of Indonesia changed 3 times, from Suharto to Habibie; from Habibie to Wahid; and from Wahid to Megawati. In addition, after the September 11th incident, the whole international environment has changed as well. Therefore, is there any change to the national security parameters of Indonesia in such a new era? The purpose to this research project is to find out what has happened to Indonesian national security priorities in the post-Suharto period. To a certain extent, the security goals of those post-Suharto governments are almost the same as during the Suharto period---maintaining national unity and integrity plus restoring Indonesia’s international creditability, in order to achieve a stable country. However, after the September 11th incident, the world has been pushed on to a “war on terror” led by United States, and the explosion on the island of Bali in October 2002 have suddenly put Southeast Asia on the frontline of the “war on terror” and heightened concerns about the threat of terrorism to Indonesia’s national security and its national credibility. Therefore, will terrorism become a new threat to Indonesia? How deep is the impact that terrorist activities can make on Indonesia? In order to answer the above questions, this thesis will be focusing on three aspects; firstly, how terrorism intensifies the pre-existing internal security threats of Indonesia. Secondly, the emergence of ‘new terrorism’ in the contemporary Indonesian political economy. Thirdly, the limitations on or difficulties for the Indonesian government in tackling terrorism

Effect of changing window type and ventilation strategy on indoor thermal environment of existing garment factories in Bangladesh

This paper presents two workable solutions that can significantly improve the indoor thermal environment within workspaces in existing ready-made garment (RMG) factories in the tropical climatic context of Bangladesh. The research involved field studies in three multi-storey factory buildings, interviews with workers and owners and simulation studies. Field data indicated that the existing window configurations and limiting the ventilation strategy to occupied hours caused overheating of the indoor environment. Among a list of proposals, the building owners saw value in implementing two solutions (i.e. altering existing window type to one with a higher effective opening area and adopting a night-time ventilation strategy) in their existing buildings as well as proposed new buildings. To quantify the benefits, a validated simulation study was conducted. The findings confirm that these two interventions can provide reductions of up to 23% in overheated working hours and in so doing, improve workers’ thermal comfort and well-being

UW-BHI at MEDIQA 2019: An Analysis of Representation Methods for Medical Natural Language Inference

Recent advances in distributed language modeling have led to large performance increases on a variety of natural language processing (NLP) tasks. However, it is not well understood how these methods may be augmented by knowledge-based approaches. This paper compares the performance and internal representation of an Enhanced Sequential Inference Model (ESIM) between three experimental conditions based on the representation method: Bidirectional Encoder Representations from Transformers (BERT), Embeddings of Semantic Predications (ESP), or Cui2Vec. The methods were evaluated on the Medical Natural Language Inference (MedNLI) subtask of the MEDIQA 2019 shared task. This task relied heavily on semantic understanding and thus served as a suitable evaluation set for the comparison of these representation methods

Resiliencia, significado en la vida y satisfacción vital: un análisis de los efectos moderadores

While presence of meaning in life (i.e., presence) is associated with a plethora of desirable qualities (e.g., greater well-being, longevity, positive affect), search for meaning is associated with psychological distress (e.g., reports of conflict, rumination, depression; Boyle, Barnes, Buchman, & Bennett, 2009). Individuals with higher resiliency, defined as a multifaceted competency in adapting and recovering from adversity, could potentially mitigate the distress associated with search, and thus, achieve greater satisfaction with life (SWL). The present study examined the moderating role of meaning in life between resiliency (i.e., sense of mastery and sense of relatedness) and SWL in a sample of Canadian university students (N=289). Hierarchical regression analyses showed that there was a positive association between resiliency and SWL and this association was stronger at higher levels compared to lower levels of search for meaning. These results suggest that individuals searching for meaning with high levels of mastery have the greatest SWL, while their counterparts with low mastery have the lowest SWL. Similar moderating effects of search were found with the positive association between sense of relatedness and SWL. Overall, findings suggest that protective factors in resiliency may buffer against the potential negative impact of search. While presence of meaning in life (i.e., presence) is associated with a plethora of desirable qualities (e.g., greater well-being, longevity, positive affect), search for meaning is associated with psychological distress (e.g., reports of conflict, rumination, depression; Boyle, Barnes, Buchman, & Bennett, 2009).

Print Media Response to SARS in New Zealand

To examine the media response to severe acute respiratory syndrome, we reviewed New Zealand's major newspaper (261 articles for 3 months). While important accurate health messages were frequently included, some were missed (e.g., hand washing in only 2% of articles). No incorrect information was identified, and health spokespersons were accurately quoted

The evolution of pellet size and shape during spheronisation of an extruded microcrystalline cellulose paste

The process by which cylindrical rods of soft solid paste extrudate are converted into round pellets on a spheroniser (Marumeriser™) plate was studied by interrupting spheronisation tests and measuring the size and shape of the pellets. Batches of 20 identical rods (20 mm long, 3 mm diameter) generated by ram extrusion of 47 wt% microcrystalline cellulose/water paste were spheronised at rotational speeds, ω, between 1200 rpm and 1800 rpm on a laboratory spheroniser. The time to complete spheronisation was found to scale with ω−3.6, which was close to the ω−3dependency predicted by a simple collision model. Breakage occupied the first 10% of the process duration: rounding off was the rate-determining step. The evolution of pellet shape was classified into five stages, the duration of which was found to scale with spheronisation time. Pellet shape, quantified by aspect ratio, circularity, shape and angularity factors presented by Sukumaran and Ashmawy (2001), showed similar behaviour for all ω studied. A phenomenological model is proposed which identifies different routes for small and large rod breakage products.This is the accepted manuscript of an article originally published in Chemical Engineering Research and Design.
