Kebakaran hutan merupakan salah satu bentuk gangguan ekologis utama yang menyebabkan perubahan besar terhadap struktur dan fungsi ekosistem, khususnya pada karakteristik vegetasi dan sifat-sifat tanah. Hutan Gunung Lawu yang berada dalam wilayah pengelolaan BKPH Lawu Selatan, KPH Lawu Ds, telah mengalami beberapa kejadian kebakaran selama dua dekade terakhir. Penelitian ini bertujuan untuk mengkaji karakteristik vegetasi pada berbagai tahap suksesi, menilai sifat fisik-kimia tanah, serta mengidentifikasi spesies pionir potensial yang mampu beradaptasi di lingkungan pasca kebakaran. Penelitian dilakukan pada tiga tahapan suksesi yang direpresentasikan oleh semak belukar (kebakaran tahun 2019), hutan sekunder muda (kebakaran tahun 2015), dan hutan sekunder tua (kebakaran tahun 2002). Pengambilan data vegetasi dilakukan menggunakan metode petak berjenjang, sementara analisis tanah mencakup pengukuran pH, c-organik, n-total, rasio C/N, kapasitas tukar kation, kejenuhan basa, dan bulk density. Hasil penelitian menunjukkan adanya pergeseran dominasi spesies dari spesies Schima wallichii menjadi spesies Lithocarpus sundaicus pada hutan yang lebih klimaks. Penilaian sifat fisik dan kimia tanah menunjukkan hasil yang bervariasi. Biomassa meningkat seiring proses suksesi mencerminkan perkembangan ekosistem.
While Product-Service Systems (PSS) have a potential sustainability impact by increasing a product’s life and reducing resource consumption, the lack of ownership might lead to less responsible user behavior. Smart PSS can overcome this obstacle and guarantee correct and safe PSS use. In this context, intelligent connected vehicles (ICVs) with PSS can effectively reduce traffic accidents and ensure the safety of vehicles and pedestrians by guaranteeing optimal and safe vehicle operation. A core subsystem to support that is the collision-warning system (CWS). Existing CWSs are, however, limited to in-car warning; users have less access to the warning information, so the result of CWS for collision avoidance is insufficient. Therefore, CWS needs to be extended to include more elements and stakeholders in the collision scenario. This paper aims to provide a novel understanding of extended CWS (ECWS), outline the conceptual framework of ECWS, and contribute a conceptual modeling approach of ECWS from the smart PSS perspective at the functional level. It defines an integrated solution of intelligent products and warning services. The function is modeled based on the Theory of Inventive Problem Solving (TRIZ). Functions of an ECWS from the perspective of smart PSS can be comprehensively expressed to form an overall solution of integrated intelligent products, electronic services, and stakeholders. Based on the case illustration, the proposed method can effectively help function modeling and development of the ECWS at a conceptual level. This can effectively avoid delays due to traffic accidents and ensure the safety of vehicles and pedestrians.

In broccoli production a big challenge is preparation of seedlings, which must be delivered during a strictly defined period to vegetable producers that are often in distant places. The goal of the present study was to investigate the response of 5-week old broccoli transplants cv. Parthenon F1 to 2 and 6 weeks of storage at 4 °C under two LED light spectra (L1: 29% red 660 nm + 14% red 630 nm + 42% blue 250 nm + 15% green 520 nm and L2: 38% red 660 nm + 18% red 630 nm +26% blue 450 nm + 15% green 520 nm + 3% UV-A 330 nm; photoperiod 16/8 h day/night and PPFD 30 ± 10 µmol m−2 s−1) and darkness. Control 5-week-old seedlings were not stored. Light treatment improved the morphology and physiological parameters of seedlings. The yield of broccoli from control seedlings was similar to that obtained after L2 treatment, regardless of seedling storage duration. The most promising effects were obtained by adding 3% UV-A radiation to the lighting spectrum. The results are applicable to the transport of broccoli transplants to remote locations or storage for several weeks, in cases where it is necessary to delay planting.

Background: Detailed knowledge of cervical canal and transverse foramens’ morphometry is critical for understanding the pathology of certain diseases and for proper preoperative planning. Lateral x-rays do not provide the necessary accuracy. A retrospective morphometric study of the cervical canal was performed at the authors’ institution to measure mean dimensions of sagittal canal diameter (SCD), right and left transverse foramens’ sagittal (SFD) and transverse (TFD) diameters and minimum distance between spinal canal and transverse foramens (dSC-TF) for each level of the cervical spine from C1-C7, using computerized tomographic scans, in 100 patients from the archives of the Emergency Room. Results: Significant differences for SCD were detected between C1 and the other levels of the cervical spine for both male and female patients. For the transverse foramen, significant differences in sagittal diameters were detected at C3, C4, C5 levels. For transverse diameters, significant differences at C3 and C4 levels. A significant difference of the distance between the transverse spinal foramen and the cervical canal was measured between left and right side at the level of C3. This difference was equally observed to male and female subjects. Conclusion: CT scan can replace older conventional radiography techniques by providing more accurate measurements on anatomical elements of the cervical spine that could facilitate diagnosis and preoperative planning, thus avoiding possible trauma to the vertebral arteries during tissue dissection and instrument application.
This paper explores the impacts of crop farmers - herdsmen conflict on crop farmers’ livelihoods in Asante Akim North District, Ghana, with a special focus on the socio-economic and ecological effects. In the past, crop cultivation and livestock grazing have existed together in harmony in West Africa, but current land and resource factors, such as population pressure, rising environmental stress, population migrations, and cultural frictions, have resulted in violent conflict. Such conflict leads to the destruction of farmland, the elimination of crops, food insecurity, the rise of poverty, and distress, especially amongst women. Using the qualitative method of semi-structured and unstructured interviews, the study evaluates the conflict management practices, which are mostly ineffective because of the lack of participation of the stakeholders, unacceptable compensation, institutional prejudices, and language difficulties. Competition over resources is made even worse by environmental pressures, climate change, and demographic shifts. The findings show the necessity of sustainable land management, including the step of stakeholder involvement, building capacities of the local institutions, and regional collaboration to promote peace and resilience. Recommendations involve enhancing the voice of stakeholders, setting up equity-based compensation schemes, and encouraging conflict resolution provisions based on dialogue. The results support the relevance of a comprehensive, long-term conflict prevention and rural development approach and feed useful information to policymakers, development practitioners, and local communities seeking operational relevance of sustainable peace and socio-economic sustainability in West Africa.
Um „compliant“ zu sein, müssen Unternehmen personenbezogene Daten Dritter schützen, die in ihrem Unternehmen verarbeitet werden. Zugleich sind sie als Arbeitgeber aber auch zum Schutz der personenbezogenen Daten ihrer Beschäftigten verpflichtet. Um ihren Compliancepflichten nachzukommen, sind Arbeitgeber also einerseits zur Überwachung der Beschäftigten verpflichtet, andererseits müssen sie dabei aber auch die datenschutzrechtlichen Vorschriften bezüglich der Verarbeitung der Beschäftigtendaten beachten. Damit stehen Arbeitgeber vor der herausfordernden Aufgabe, alle Interessen und Pflichten bestmöglich in Einklang zu bringen. Diese Dissertation zeigt mögliche Lösungswege für dieses Dilemma auf.
