OpenStreetMap User's Diaries: People spamming diaries with irrelevant comments

OpenStreetMap diaries are a great way to communicate with the community worldwide. Since past few months, few of us are receiving irrelevant comments on our diary posts from users who mostly have no edits (likely that they are new to OpenStreetMap)

Some examples of such comments are:

  • This is a snapshot from a diary post by SrrReal, which has many such comments.

  • Can there be a way, where we can close the option to comment on a diary post after a particular period?
  • Is there a possibility of deleting such comments from the post?
  • Is anyone else also facing similar issues?

OpenStreetMap User's Diaries: Beekeeper at Work

Yesterday I was walking in Montes de Málaga and I observed a beekeeper working. How to map an apiary in OpenStreetMap? I thought maybe there were no tags for this feature, but I was wrong! There are tags to map apiaries, beehives, expositions and even the beekeeper's house.

OpenStreetMap User's Diaries: OSM im Auto

Nachdem ich jetzt meinen Landkreis soweit aufbereitet habe, dass die Navigation brauchbar ist, habe ich die Gelegenheit genutzt und mich mal über das Navigations- und Mediasystem meines Autos genauer informiert.

Das System basiert auf Linux, der Zugang gelingt über USB oder SSH (WLan), Benutzer und Passwort sind Standard mit maximal 4 Zeichen. Das öffnet schon mal jedem kleinen Bastler Tür und Tor.

Aber man muss nicht. Ich hab jetzt eine App entdeckt, mit der ich nicht nur Musik oder Videos auf dem Display und Soundsystem des Autos abspielen kann, sondern auch das Display spiegeln. Alles was dazu nötig ist, ist eine kleine Software auf einem USB Stick, der beim Anstecken in den Hauptspeicher geladen wird. Die Software muss also gar nicht verändert werden.

Ich hab mir dadurch nicht nur ein Update auf Android Auto gespart, sondern auch die veraltete Navigationssoftware eingespart.

Der Urlaub kann kommen!

OpenStreetMap User's Diaries: Dental Examination & Orthodontic Surgery

Dental Examination & Orthodontic Surgery

The dental examination is an area of physical diagnosis that usually be neglected in the medical curriculum. However, we can get a lot of information through a systematic evaluation of the oral hard and soft tissues. Although the primary objective is to distinguish between health and disease, a comprehensive oral examination can also provide valuable information to the overall health. In many instances, it is an indispensable component of patient assessment to cancer therapy. Generally speaking, your physical condition can be evaluated just by your oral health condition. Oral examinations also have an important influence on the classification of HIV-infected patients, the oral findings often determining the eventual antiretroviral therapy.

The dental examination is a systematic process. The dentist will investigate your oral and systemic health in order to confirm pathologies or concerns and develop a specially formulated treatment plan to maximize your oral health. The second step of any oral health exam involves a complete examination of your teeth and supporting structures. This involves the incorporation of several techniques, technologies and therapies.

Your dental hygienist explores every surface of every tooth to discover new cavities and examine the quality of existing fillings with a crown horn or fishhook, two commonly used dental instruments. Over time, fillings can break down and require replacement. They may also be replaced for improved esthetics. In fact, many people today opt to remove their older silver amalgam fillings and replace them with natural-looking composite fillings.

Healthy gums adhere tightly to the teeth. If they don't, there will be a possibility of getting periodontal disease or bone loss. The dental hygienist typically performs periodontal probing to measure the circumference of each tooth and the strength of the supporting bone structure. An accurate probe is inserted between the teeth and gums to measure the level of "gum adherence" to the teeth. The hygienist will record a millimeter number for every tooth. The goal is to record a number of one, two or three. A number of four or more indicates periodontal disease and potential bone loss. If the gums do not tighten after the cleaning, you will be scheduled for a scaling or Root Planing appointment.

Here is some of what your dentist is looking for during a dental exam: 1. Damaged, missing or decayed teeth 2. Early signs of cavities 3. Condition of your gums, such as periodontal pockets, inflammation or other signs of gum disease (which can lead to tooth and bone loss) 4. To see how previous dental work such as root canals, fillings and crowns are holding up 5. Early signs of mouth or throat cancer, such as white lesions or blocked salivary glands 6. Other suspicious growths or cysts 7. Position of your teeth (spacing , bite) 8. Signs that you clench or grind your teeth (a treatable problem that can cause headache or sore jaw and can, if serious, lead to hearing loss and tooth loss) 9. Signs of bleeding or inflammation on your tongue and on the roof or floor of your mouth 10. The overall health and function of your temporomandibular joint (which joins the jaw to skull), checking for signs of disorders that can cause pain or tenderness. 11. The general condition of the bones in your face, jaw and around your mouth

Orthognathic surgery is not a new technique or area of maxillofacial surgery microscope. The conceptualization and early practice of this form of surgery have been around for many decades and the most recent technology has been practiced for nearly thirty years. Due to the continuing modernization of instruments and techniques of stabilization the elective treatment of a patient with this form of surgery has become safer, more comfortable, and more reliable. Procedures that once demanded nearly ten hours of surgery have been shortened to as little as three to four hours. Hospitalizations for surgery that would often necessitate four to six days as an inpatient and may have involved a period of time in the intensive care unit, now allow for discharge on the first post-operative day.

OpenStreetMap User's Diaries: The Relationship between Wound Dressing and Wound Healing

The Relationship between Wound Dressing and Wound Healing

Wound healing is a normal biological process of the human body. We have to get through four precisely steps: hemostasis, inflammation, proliferation, and remodeling. If you want the wound to heal successfully, all of the steps must occur in the right order and time range. A lot of factors can interfere with one or more steps of this process, thus causing wound healing more slowly with worse recovery. These elements include oxidation, infection, age and sex hormones, pressure, diabetes, obesity, medications, drinking, smoking, and nutrition. So, it is very important to understand the influence of these elements. It may improve the speed of wound healing and impaired wound healing.

According to the characteristic of the impaired wound healing, wounds fall into acute wounds and chronic wounds. Acute wounds are usually tissue damages have been fully recovered, with small scars, within the estimated time range, usually 8-12weeks. The main reason that caused acute wounds include mechanical injuries on account of exterior factors, such as abrasions and tears that caused by contact with friction between the skin and hard surfaces. On the other hand, chronic wounds result from slow-healing of tissue injuries, that is have not healed over 3 months and often relapse. Repeated tissue insults or optional physiological condition is the reason why such wound is hard to cure.

Successful treatment of impaired wound healing depends on comprehending the type of wound that is under treatment, the recovery process, and health condition of patients. In some cases such as chronic wounds, there is an excess of exudates present which can result in complications. A main feature of modern wound dressings is to get rid of the extra exudate while maintaining moisture at the wound bed. Wound dressings are designed to keep the wound clean, pollution-free and also to promote wound healing, especially in chronic wounds where there may be significant tissue loss.

Advanced wound dressings are used in wounds as providing a moist environment on wound healing process. It is good for the dissolution of necrotic tissue and reduces the probability of infection. WH Hydrocolloid wound dressing is one of the best choices. Hydrocolloid is a material containing gel-form agents, such as carboxymethycellulose and gelatin. It is used to wound management, providing a moist environment for wound to accelerate wound healing process. Semi-transparent features is better for observe wound healing process. PU film surface, water-proof is reduces the risk of roll up and bunching.

WH Pore wound dressing is a soft cloth adhesive wound dressing. Soft and hypoallergenic applied as a primary or second dressing over light to moderately draining wounds. It’s convenient to fixed devices or for protecting I.V. cannula sites. No scab formation to prevent second hurt from dressing changes.

OpenStreetMap User's Diaries: Clinical Indications investigation for Colposcopy

Clinical Indications investigation for Colposcopy

Cervical Pathology is the science of the causes and effects of diseases related to cervix with laboratory examination for diagnostic purposes. Major diseases of Cervix include: Cervical endometriosis, Ectropion and endocervicitis etc. Cervical cancer prevention depends upon detection and treatment of high-grade (CIN2,3) cervical lesions most likely to progress to invasive cancer in the absence of treatment. Two primary cervical screening tests are now in use The Pap test, which includes the conventional Pap smear and the liquid-based Pap test. A colposcopy is a close-up view of the cervix, vagina and vulva for signs of disease. It is used to detect abnormal cells on the cervix. During a colposcopy procedure, physician uses a colposcope — an instrument that looks like binoculars with a bright light mounted on a stand. Colposcopy is usually done in one of two circumstances: to examine the cervix either when the result of a Pap smear is abnormal, or when the cervix looks abnormal during the collection of a Pap smear.

All of the world, it is estimated that there are 528,000 new cases of cervical cancer each year and that 266,000 women die from the disease. In the United States, the National Cancer Institute (NCI) estimates that 1,200 new cases of cervical cancer will be diagnosed in 2015, and that 4,100 women will die from the disease. Currently, the five-year survival rate for localized cervical cancer is 91.5%; the overall (i.e., all stages combined) five-year survival rate is approximately 67.8%. Cervical cancer was once one of the most common causes of cancer death among U.S. women, but since the 1980s, the cervical cancer death rate in the United States has decreased by more than 50%.

Studies show that access to health care is an important predictor of cancer screening. In the United States, pap tests are ordered or provided in approximately 29.4 million physician office visits each year, and it is estimated that more than 3 million women get unclear or abnormal results.

Colposcopy is the diagnostic test indicated for evaluating patients with abnormal Pap test results. 7During the procedure, features of the cervical epithelium are examined under magnified illumination after the application of normal saline, 3% to 5% dilute acetic acid, and Lugol iodine solution in successive steps. A green filter highlights vascular patterns. colposcopy is usually done in one of two circumstances: to examine the cervix either when the result of a Pap smear is abnormal, or when the cervix looks abnormal during the collection of a Pap smear. Even if a Pap smear result is normal, colposcopy is sometimes necessary when the cervix appears visibly abnormal to the clinician performing the Pap smear. The purpose of the colposcopy is to determine what is causing the abnormal looking cervix or the abnormal Pap smear so that appropriate treatment can be given.

Neither cytologic sampling nor colposcopic examination alone provides definitive answers. If abnormal tissue is present, it is the histologic result that provides the basis for treatment or observation.

Colposcopy – the traditional next step after an abnormal smear test – relies on the presence of visible indicators to detect atypical cells on the cervix. Unfortunately, these indicators are not specific to cervical intra-epithelial neoplasia (CIN), especially low-grade CIN, which means that interpretation is subjective. That’s why we take biopsies to confirm the presence of disease before offering treatment. But biopsies are invasive – and as it can be difficult to judge the best location, we sometimes need to take more than one tissue sample, which can add to patient discomfort. Even after the biopsy is complete, it can take up to two weeks to receive the histology results, making waiting patients understandably anxious. In the majority of cases, the abnormal tissue will regress naturally, so to avoid unnecessary and potentially harmful treatment, we tend to recall these patients for repeat colposcopy at six 12 month intervals – only increasing the time and effort, in addition to uncertainty for the patient.

OpenStreetMap User's Diaries: Disappearing Streams, Disappearing Footpaths

My last survey included the best-surfaced unadopted=yes road that I've yet seen:– Waterhouse Lane. In the course of that survey I discovered:–

  1. Why Willow Brook was dry
  2. Yet another stolen footpath

Who stole Willow Brook?

One of the residents on Waterhouse Lane told me that it was so-called due to a Water Pump that originally existed in that lane. Well, not only that Pump has gone; the residents appear to have stolen the local stream as well!

There is a photo in the 17 April Diary of the dry riverbed of the local stream, shot over the fence from Willow Farm School. A very kind lady at 11 Waterhouse let me take a photo of the stream from the bottom of her garden (from the opposite bank to the school), but her plot does NOT include the stream. This is shot over the top of her fence; the stream is supposed to run right-to-left, and the stream-bed is at the base of the tree in the centre of this photo:–

willow brook dry riverbed

That is NOT a very useful photo & I was having lots of difficulty with this stream. Eventually, I teased out a fuller story...

The modern OS-OpenData_StreetView imagery (available within JOSM and obtained from os.openstreetmap.org) shows a stream beginning at the north-end of the Primary School field then running all the way down the side of the school (the link is to a culvert that I've put in place of the stream). It is most unlikely that a stream would suddenly appear from nowhere, so where is the source?

I finally found the stream on a 1920s OS map (it is possible that you may need to choose “OS 1920s” as the Background Map as to show the blue of the stream). Having walked that land & talked to the Farmer I'm now certain of the source.

Gedling Wood Farm today sits at the base of a little triangle of wood which in the 1920s was the bottom of a continuous Gedling Wood that stretched up to Crock Dumble. The stream shown on the 1920s Ordnance Survey map is almost due north-south, runs parallel to the modern/ancient footpath to Lambley & begins at the same line as the Dumble (and the top of the modern GWF field called 2-ponds). Even the modern hedges seem to follow the line of the stream, and I noticed an east-west ditch at the base of a possible drover's road (fuller explanation in 12 April Diary).

That ancient footpath today in part follows modern roads, but it still gets all the way from the fields above Almond Walk down to the top of Waterhouse Lane. Now, that footpath used to travel close to the old stream, so where is the stream now? I cannot answer for Tamarix Close or the streets above (presumably it was culverted along the line of the footpath), but I got tales of streets below...

The whole of the land between the stream & Waterhouse Lane was owned by a lady that lived in a single bungalow on site. It was all sold to a builder who put up the modern houses. The chaps in the houses at the north end of Waterhouse Lane told me that they followed the earlier inspiration of the actions of the builder & buried the stream within plastic pipes (essentially culverted, which is why I changed the ‘stream’ to a ‘culvert’).

Today, only a small section of the south end remains as a stream-bed. However, the stream-bed is dry, and I suspect that those pipes have collapsed... Severn Trent put a metre-high culvert under the (former) Mineral Railway. I doubt that those builder's pipes are a fraction of that size, or strengthened against collapse. Ah well.

OpenStreetMap User's Diaries: OpenStreetMap Bangladesh: Upcoming Programs

First, I would like to congratulate the YouthMappers at AUW for wining the HOT micro-grant award with other seven communities globally. I would also appreciate other micro communities and chapters for competing the micro grant program and wish you luck for the next one. I would like to congratulate YouthMappers DhakaCollege, YouthMappers at AUW for wining 2017 chapter award, Maliha Mohiuddin from OpenStreetMap Dhaka University for wining best blog award 2017 and also other three chapter members for wining the leadership award and going to participate in workshop to be held in Nepal.

Let me give you some upcoming mapping programs that are under discussion but hoping to be launched soon:

  1. There will be a series of mapathons for mapping the existing features of 13 coastal districts of Bangladesh what we want to organize in a different manner. We will call for application/proposal from chapters, micro-communities, universities who wants to hold the mapathon/s at their premises. The selected will have the required training, logistics, appreciation certificate. I shall call for the application within a month or two.

  2. BDRCS Volunteers are going to be engaged soon for community level training and mapping. We are planning to expand the mapping of vulnerable buildings for urban resilience where the city ward emergency response committee members will be taught how to and map their respective wards. In near future we want to replicate for disaster vulnerable districts too.

  3. To find and enhance more use cases of existing OSM data in Bangladesh we would like to call for participation of a research teams, person/s in a research grant program . The selected teams or persons have to come up with scoping ideas showing result of spatial analysis, vulnerability assessment, risk analysis, scenario modeling or future projections. I will invite the potential universities and also open call for other researcher or team when we are ready.

  4. I want to map the Nijhum Dwip - নিঝুম দ্বীপ, one of the most vulnerable island in Bangladesh where loss of lives and livelihoods are common matter due to cyclone and storm surge. I would request some volunteers to assist me in field level data collection and mapping in next month.

  5. Finally, I am very happy that more and more service delivery and routing startups are using OepnStreetMap for their application. NerdCats team is going to update their Bus rout app based on openstreetmap after their famous and successful app GO! Traffic Updates (by GObd.co). Pathao service wants to use and update the roads of whole Dhaka city, for that they are going to organize a mapathon in 29th of this month jointly with OpenStreetMap Bangladesh community. I am requesting all the members of our community to join this mapathon and help Pathao to make a better and detail dhaka map.

Thanks. I wish you all the best in coming days. Happy new Bangla Year 1424.
