Ancak, tüm bu güvenlik önlemleri alındığında bile, işçinin yorgunluğunun güvenlikte kritik bir rol oynadığı unutulmamalıdır. Yorgun bir işçi, ne kadar güvenlik protokolü olursa olsun, bu protokolleri uygulamakta zorlanabilir. Bu nedenle, özellikle dikkat ve özen gerektiren endüstriyel görevlerde, çalışanların yorgun olup olmadığını belirlemenin hayati öneme sahip olduğu kabul edilmiştir. Çalışmamızda, işçilerin uzun ve kısa vadede işlerini sağlıklı bir şekilde sürdürebilmeleri adına yorgunluk tespitine odaklandık. Bu bağlamda, gerçek zamanlı video görüntülerini kullanarak, görüntü işleme teknikleriyle yüz tespiti gerçekleştirildi ve yüzdeki belirli referans noktaları haritalandı. Göz ve ağız açıklığı ile başın eğiklik seviyesi, yorgunluk belirtileri olarak belirlendi ve bu parametreler eşik değerlere göre değerlendirildi. Ayrıca, işçinin dikkatini ve bilgisini ölçmek amacıyla yorgunluk tespit sırasında iş sağlığı ve güvenliğiyle ilgili sesli ve görsel sorular da sorulmuştur. Böylelikle işçinin belirli iş aktiviteleri ve ekipmanlar için ne kadar hazır olduğunu belirlemeye çalıştık. Ek olarak, sistem, yüz tanıma teknolojisiyle bireysel yorgunluk raporları hazırlayabilmektedir. Gerçekleştirilen deneysel çalışmalar sonucunda önerilen sistemin doğruluğu %80, kesinliği %85, duyarlılığı %73 ve F1 skor değeri %75 olarak hesaplanmıştır.","PeriodicalId":492415,"journal":{"name":"International journal of advances in engineering and pure sciences","volume":"28 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141665037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utilization of drones in diverse sectors raises concerns about their vulnerability to potential attacks that disrupt or obstruct their operational mechanisms. In this work, we first demonstrate how navigation attacks can compromise a drone’s system, using GPS jamming and spoofing attacks via HackRF One PortaPack Software Defined Radio (SDR) device. Next, we propose a mechanism called “Return-to-Start”, which can protect a drone from loss by responding promptly to such widely spread navigational attacks. We evaluate the effectiveness of our solution through experiments on a Raspberry Pi-based drone we developed. Our experiments validate the robustness of Return-to-Start functionality in a variety of attack scenarios with different durations and GPS geolocations.","PeriodicalId":492415,"journal":{"name":"International journal of advances in engineering and pure sciences","volume":"95 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new study, investigating effects of metformin treatment on colorectal cancer cells, pointed to the fact that response to metformin treatment depended on extracellular glucose concentration. That is why in the current study, effects of both carbon limitation and metformin treatment are explored via transcriptomics analyses. It is demonstrated that cells grown in glucose-limited and metformin treated medium had the highest variance according to transcriptional profiles, compared to individual treatments. Metformin administration, when combined with glucose restriction, downregulates proliferative pathways such as transcription initiation and ribosome biogenesis while upregulates energy derivation and autophagic mechanisms. Enrichment analyses point to an attenuated cAMP-PKA signaling pathway in the cells grown in combined treatment medium. It is proposed that combined treatment exerts its beneficial effect on this pathway, since cAMP-PKA signaling may be a potential target for pharmacological treatment of tumors.","PeriodicalId":492415,"journal":{"name":"International journal of advances in engineering and pure sciences","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136277222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to this interest, it also attracted the attention of crime and crime organizations in a short time, and over time it turned into a tool used by illegal organizations such as laundering the proceeds of crime. Although this structure was initially exposed to the reaction of some states at the level of nation states, on the other hand, it managed to get the support of many states. However, although the spread of blockchain-based money laundering methods is an undeniable problem for all states, a significant cooperation has not been achieved by international collaborations and organizations to prevent this situation. On the other hand, it is of great importance for law enforcement and forensic analysts to clarify this situation and to fight against these structures in order to protect national interests. In this study; In this study, an approach that will detect money laundering is tried to be presented through sample scenarios by bringing a broad perspective to crypto money-based money laundering methods, which are very difficult to trace due to their nature.

Material properties such as density, hardness, surface gloss at a 60° angle, and Charpy impact strength were measured according to varying rEPS ratios. The results showed that rEPS bubbles reduced density, thereby reducing the weight of the material, affected surface gloss, and decreased impact strength. There was no significant difference in hardness values, but impact strength decreased with increasing rEPS content. The effects of homogeneous distribution of rEPS bubbles on material properties were examined, and it was emphasized that the use of rEPS should be optimized with appropriate production processes.
