Water management in hotels using tap specs in conjunction with the Ishikawa approach
No full textThe hotel and tourist industries rely heavily on average water consumption. The establishment and maintenance of a water conservation culture in hotels is the responsibility of industry professionals in this field. For determining the root cause of a problem and devising a workable solution, researchers often use the Ishikawa technique invented by Ishikawa in 1943, also called the fishbone diagram. This case study demonstrates how water tap specs can be used in conjunction with the Ishikawa approach to achieve water savings in hotels. As an added benefit, this case study illustrates how the outcomes of this approach can be assimilated in standard operating procedures (SOPs) in the accommodation business

No full textRobot navigation control based on monocular images: An image processing algorithm for obstacle avoidance decisions
Get PDFThis paper covers the use of monocular vision to control autonomous navigation for a robot in a dynamically changing environment. The solution focused on using colour segmentation against a selected floor plane to distinctly separate obstacles from traversable space, this is then supplemented with canny edge detection to separate similarly coloured boundaries to the floor plane. The resulting binary map (where white identifies an obstacle-free area and black identifies an obstacle) could then be processed by fuzzy logic or neural networks to control the robot’s next movements. Findings shows that the algorithm performed strongly on solid coloured carpets, wooden and concrete floors but had difficulty in separating colours in multi-coloured floor types such as patterned carpets

No full textEpidemiology and Evaluation of results of early management of midfacial fractures in a tertiary care hospital
Get PDFINTRODUCTION:
Management of midfacial trauma occupies a major part in the speciality of plastic surgery. These injuries are commonly seen in our day to day practice. These are associated with multisystem trauma which ultimately require combined management with other specialities like Emergency Physician, Ophthalmologist, Otolaryngologist, Trauma Surgeon and Neurosurgeon.
These injuries affect various functions such as vision, hearing, breathing, smell and speech because of association of all these sensory organs in the face. Most important is the psychological impact of disfigurement of face after faciomaxillary injuries. Most of the injuries are the result of low energy impact and these can be managed with available specialized treatment techniques in plastic surgery. Whereas major injuries due to complex high energy impact are a real burden to the plastic surgeon and management involves multidisciplinary team of surgeons. It is really a challenge for faciomaxillary trauma surgeon to maintain low complication rates for severe facial injuries and also avoid undue morbidity.
Motor vehicle accidents in patients who did not wear helmets have produced major facial injuries. The bones most commonly involved were Zygoma, Nasalcomplex and Mandible. In urban areas the most common cause of facial injuries are due to motor vehicle accidents followed by assault, fall, industrial accidents and sports injuries.
AIM OF STUDY:
This study was done to collect and analyse current data on aetiology, biomechanics and demography of patients admitted with midfacial fractures at Chengalpattu Medical College and to assess the association of midfacial fracture with gender, occupation, social behaviour and mechanism of injury. It is also to evaluate the result of early management and its effect on functional and aesthetic outcome of midfacial fractures.
MATERIALS AND METHOD:
The study was done during the period of October 2010 to December 2012, totally for a period of 27 months. 297 cases of facial injuries were referred to the Department of Plastic Surgery during this period. Out of which only 61 cases of midfacial fractures were taken up for study.
Proforma was prepared to study the various epidemiological factors like age, gender, occupation, causes of injuries, association of injuries with alcohol consumption, usage of helmet, type of fractures, and to analyse the outcome of results of early and late management of these midfacial fractures.
This dissertation was submitted for the approval of the Human Ethical committee and the approval was granted, [Ref no.493/MEI/2007].
Verbal explanation about the study was given to the patients who fulfilled the inclusion criteria. Patients history, symptoms & signs were recorded, photos were taken, their contact address and phone numbers were collected with their consent.
Inclusion Criteria:
Midfacial fractures were included as per Frost [28] in the area bounded by frontozygomatic and frontonasal sutures superiorly and occlusal plain inferiorly, pterigoid plates posteriorly, till the root of the zygomatic arch laterally. So all the patients with fractures in the above mentioned territory were included for the study.
Exclusion Criteria:
Fractures involving Frontal bone and Mandible were excluded.
When patients were referred to our department all details were recorded in the proforma. Patients age, sex, occupation, residential address and contact number were noted first. Mode of injury was recorded as road traffic accidents (RTA), assault, fall, industrial accident and sports injury. In RTA option, whether the patient was a pedestrian, bike rider, or pillion rider was recorded. History of alcohol consumption during driving was noted. Usage of helmet during driving by the rider and pillion rider was recorded. The site of accident, whether occurred on the street, or road within the urban area, or on the national highway were recorded. Whether the accident had taken place during day time or night time was also recorded.
RESULTS:
In a total of 61 patients, details of history, examination findings, operation records, follow up photos and the results were entered in the proforma. The master chart was then prepared and the results were analysed.
Out of 61 patients, 53 patients were males and 8 patients were females. Gender distribution revealed male predominance in a ratio of 5:1. Out of 53 male patients, 20 (37.7%) were involved in the age group of 20 to 30 yrs. It was followed by 16 patients in the 31 to 40 year age group. There were very less patients in both extremes of age group, that is below 20 and above 60 yrs. In the 20 to 30 yrs age group all were involved in road traffic accidents. In the female population more number of patients (50%), were in the 41 to 50 yrs age group. The main cause of the injury was assault, followed by fall and lastly road traffic accidents. This pattern is very different from men. Main cause of injury was road traffic accidents (49.2%), followed by assault (18%). Out of 37 patients who were involved in the two wheeler accidents, bike riders were more than the pillion riders. Majority of the injuries have taken place on the roads (64.0%), within the city and around the nearby villages. 22% of injuries have occurred at home due to assault and fall. Out of 61 cases 30 (49.1%) were under the influence of alcohol among all the cases of midface inury. Out of 37 cases of road traffic accidents only two of them had used helmets (5.4%), rest of the 35 patients (94.6%) did not use helmet. 52% of injuries have occurred during the day time. Main symptom was pain in 95% of patients, followed by difficulty to open the mouth (65.6%). Loss of sensation in infraorbital region (42.6%), was the next common symptom. About 40 patients (65.6%) had step in the infraorbital rim, zygomatico frontal suture line and in the zygomatic arch. Trismus was the next common sign (63.9%). Around 50% of them had subconjunctival echymosis and malar flattening. Isolated zygoma fracture was the most, comprising 49.2% of the total cases. Out of these, left zygoma fractures were more than right. Zygomatico maxillary complex fractures followed by 26.2 %. Two patients had Le Fort II & III on either side of the face.
CONCLUSION:
This study shows that the incidence of midfacial fractures were more in males of 20 to 30 years age group than in females who were between 40 to 50 years. The main cause in men were road traffic accidents and assault in the case of women. Most of the men were of low socioeconomic group comprising of farmers & labourers whereas the women were all housewives. There is a strong correlation with alcohol consumption and helmet defaulters with severe midfacial injuries due to road traffic accidents. There is a significant correlation with increased incidence during some months in a year when there are environmental changes, increased work load and holiday season which could have resulted in more travelling. When compared to delayed management, early management of midfacial fractures showed better results functionally and aesthetically with less complications
