No full textУльтразвуковая оценка ядра окостенения проксимального эпифиза бедренной кости у детей до 1 года
No full textBackground. Developmental disorders of the secondary ossification center (SOC) of the proximal femoral epiphysis can be a marker of some childhood diseases that require timely diagnosis and treatment.
The study aimed to assess the capabilities of ultrasonography in the diagnosis of ossification processes of the proximal femoral epiphysis.
Material and Methods. The study is based on the results of a survey of 524 children aged 2 weeks to 1 year with normal hip joints, including 259 boys and 265 girls. All patients underwent ultrasound examination of the hip joints according to the method of R. Graf in a standard coronary section. In older children, to eliminate errors in measuring the size of the SOC, an additional cross-section was used.
Results. The SOC was detected in isolated cases in boys aged up to 3 months and girls up to 2 months. At age 3 months, the SOC was visualized in 45% of girls and 5% of boys. By age 5 months, 81% of girls had a SOC compared with 46% of boys. By 7 months, SOC was determined in more than 90% of cases of both groups. Thus, girls showed an earlier formation of the SOC than boys. The SOC was located in the center of the femoral head in 82% of cases, lateral in 14%, and medial in 4%. In 95% of the examined children, SOC development occurred symmetrically in both joints. In addition, discrepancies were revealed with simultaneous ultrasonography and X-ray of the hip joints since the SOC becomes visible earlier during ultrasonography.
Conclusion. Sonography is a highly informative method for determining the ossification processes of the proximal femur. Knowledge of the normal sonographic appearance of the femoral head SOC by age and sex will help clinicians diagnose and treat hip disorders.Актуальность. Нарушение развития ядра окостенения проксимального эпифиза бедренной кости может являться маркером ряда заболеваний детского возраста, требующих своевременной диагностики и лечения.
Цель исследования оценить возможности ультразвукового исследования в диагностике процессов оссификации проксимального эпифиза бедренной кости.
Материал и методы. Исследование базируется на результатах обследования 524 детей с нормально сформированными тазобедренными суставами в возрасте от 2 недель до 1 года, среди них 259 мальчиков и 265 девочек. Всем пациентам было проведено ультразвуковое исследование тазобедренных суставов по методике Р. Графа в стандартном коронарном срезе. У детей более старшего возраста с целью исключения погрешностей в измерении размеров ядра окостенения использовался дополнительный поперечный срез.
Результаты. В возрасте до 3 мес. у мальчиков и до 2 мес. у девочек ядро окостенения выявлялось в единичных случаях, у 45% девочек в возрасте 3 мес. визуализировалось четкое ядро, у мальчиков этого возраста ядро выявлялось в 5% случаев. К возрасту 5 мес. у 81% девочек выявлялось ядро, в то время как у мальчиков оно появлялось только в 46%. К 7 мес. в обеих группах как у мальчиков, так и у девочек в более чем в 90% случаев определялось ядро окостенения. Таким образом, у девочек наблюдалось более раннее формирование ядра окостенения, чем у мальчиков. Ядро в 82% случаев размещалось в центре головки, в 14% отмечалось его латеральное расположение, в 4% ядро было смещено медиально. У 95% обследуемых детей процесс формирования ядер окостенения происходил симметрично в обоих суставах. Кроме того, при одновременной ультрасонографии и рентгенографии тазобедренных суставов были выявлены несоответствия, обусловленные тем, что при УЗИ ядро становится видимым раньше, чем при рентгенографии.
Заключение. Уникальные особенности сонографического метода, такие как неограниченный по временным интервалам и частоте мониторинг, относительно раннее выявление ядер окостенения, отсутствие лучевой нагрузки на организм ребенка, делают перспективным дальнейшее изучение и оптимизацию УЗ-метода в исследовании процессов оссификации проксимального эпифиза бедренной кости у детей раннего возраста. Ультразвуковое исследование процессов оссификации проксимального эпифиза заслуживает более широкого внедрения в практику ортопедов, детских хирургов и педиатров. Это позволит специалистам рано предвидеть будущие нарушения роста и развития проксимального отдела бедренной кости и обеспечить при необходимости раннее вмешательство
Opportunities for Reusing Textile Waste in K.B Passage OÜ
No full textTekstiilitööstus on üks suurimaid tööstuseid maailmas, mis tekitab suurtes kogustes jäätmeid. Aina
rohkem pööratakse tähelepanu antud tööstusevaldkonnas just keskkonna säästmisele ja võimaluste
leidmisele, kuidas kasutada ära järgi jäävad tekstiilid. Ringmajanduse ajastul võib tekstiilijäätmeid
pidada ressursiks uute tekstiiltoodete tootmiseks, mida tehes on võimalik vähendada
keskkonnamõjusid. Kui tarbimisjärgsete jäätmete kohta on tehtud palju uuringuid, siis
tekstiilitootmise erinevatel tootmisetappidel tekkivaid tööstusjäätmete voogusid ei ole piisavalt
uuritud ning ei ole leitud lahendusi, mida nendega peale hakata. Käesoleva lõputöö eesmärgiks oli uurida, millised võimalused on rõivatootmis ettevõttel K.B Passage OÜ tekstiilijäätmete taaskasutamisel Eestis. Ettevõttel puudus ülevaade, kui palju tekib neil tekstiilijäätmeid kokku ning kui suur kahjum see neile täpsemalt oli. Uuringu käigus koostas autor detailse ülevaate järgi jäävatest tekstiilijääkidest ning kategoriseeris
need vastavalt võimalike kasutusalade järgi. Kategoriseerimise aluseks võeti järgi jäävate
tekstiilitükkide pindalad. Lõputöö uuringus selgub, et tekstiilijäätmeid on võimalik Eestis
taaskasutada, kuid antud lahendusi ei ole hetkel piisavalt palju. Vaatluse käigus selgus, et ettevõttel
K.B Passage OÜ jääb kahe kollektsiooni peale kuus kokku 32,7 kg tekstiilijäätmeid ning rahaline
kahjum on 1093 eurot kuus ja aastane summa on 13116 eurot. Materjalidest jääb kõige rohkem järgi
villa ja puuvilla tekstiilijäätmeid. Analüüsist selgus arvutuste tulemusel, et kõikide taaskasutatavate
tekstiilijäätmete materjali kulu kokku ühes kuus on 720 eurot ja aastane summa on 8640 eurot. Seda
summat on võimalik ettevõttel päästa, taaskasutades enda tekstiilijäätmeid ja nendest ise õmmeldes
lasteriideid. Autori koostatud ettepanekud ettevõttele K.B Passage OÜ tekstiilijääkide taaskasutamiseks: Kõige optimaalsem lahendus on ettevõttel hakata ise taaskasutama enda tekstiilijäätmeid,
näiteks tehes alles jäävatest jäätmetest lasterõivaid, mida oleks võimalik müüa. Teine ettepanek oleks rakendada toote disainimisel nulljäätmete disaini, et tekiks vähem tekstiiilijääke alles, ning võimalikult suur kangast oleks ära kasutatud. Kolmas ettepanek oleks tekstiilimaterjalide ümbertöötlemine, keemiliselt või mehaaniliselt. Neljas ettepanek on ettevõttel parandada enda visuaalset juhtimist, et hakata tektsiilijäätmeid eraldi kangaste järgi sorteerima. Jätkusuutlikuks jäätmete käitlemiseks, tuleb pidevalt analüüsida tekkivate jäätmete koguseid ning leida uuenduslikke lahendusiselleks, et neid võimalikult optimaalselt ettevõtte jaoks ära kasutada.The textile industry is one of the largest industries in the world, generating large amounts of waste.
Increasing attention is being paid in this industry to saving the environment and finding ways to use
leftover textiles. In the age of the circular economy, textile waste can be seen as a resource for the
production of new textile products that can reduce environmental impact. While many studies have
been carried out on post-consumer waste, the industrial waste streams generated at different stages of
textile production have not been sufficiently studied and no solutions have been found to address
them. The aim of this dissertation was to study the possibilities of the clothing production company K.B
Passage OÜ in recycling textile waste in Estonia. The company did not have an overview of how
much textile waste they generated in total and how much of a loss it was for them. In the course of the study, the author compiled a detailed overview of the remaining textile residues
and categorized them according to the possible uses. The categorization was based on the areas of the
remaining textile pieces. The study of the dissertation shows that it is possible to reuse textile waste
in Estonia, but there are not enough solutions at the moment. During the inspection, it turned out that
the company K.B Passage OÜ has a total of 32.7 kg of textile waste per month after two collections,
and the financial loss is 1093 euros per month and the annual amount is 13116 euros. The largest
types of wastes are wool and cotton. The analysis showed that the total cost of all recyclable textile
waste material in one month is 720 euros and the annual amount is 8640 euros. This amount can be
saved by the company by reusing its own textile waste and sewing children's clothes from it. Proposals prepared by the author for the company K.B Passage OÜ for the reuse of textile waste: The most optimal solution is for the company to start recycling its own textile waste, for example by making the remaining waste children's clothes that can be sold. Another proposal would be to use a zero-waste design in the design of the product, so that less textile waste is generated and as much fabric as possible is used. The third proposal would be the recycling of textiles, chemically or mechanically. The fourth proposal is for the company to improve its visual management in order to start sorting textile waste separately by fabric. For sustainable waste management, the amount of waste generated must be constantly analyzed and
innovative solutions must be found in order to make the best possible use of it for the company
