Logistics outsourcing and 3PL selection: A Case study in an automotive supply chain

Outsourcing logistics functions to third-party logistics (3PL) providers has been a source of competitive advantage for most companies. Companies cite greater flexibility, operational efficiency, improved customer service levels, and a better focus on their core businesses as part of the advantages of engaging the services of 3PL providers. There are few complete and structured methodologies for selecting a 3PL provider. This paper discusses how one such methodology, namely the Analytic Hierarchy Process (AHP), is used in an automotive supply chain for export parts to redesign the logistics operations and to select a global logistics service provider

Ortaokullarda iş sağlığı ve güvenliği uygulamalarına yöneticilerin yaklaşımları, çalışma yöntemleri ve pandemi sürecinde uygulamaların incelenmesi: İzmir örneği

Bu araştırmada, İzmir ilindeki ortaokul müdürlerinin iş güvenliğine ve kalite yönetim sistemlerine bakış açılarını, algı düzeylerini, sorumluluk ve yetkilerine dair farkındalıklarını tespit etmek hedeflenmiştir. Yapılan bu çalışma ile normal süreçtekilere ek olarak, pandemi sürecinin yarattığı sorunlar ve yöneticilerin uyguladığı/önerdiği yöntemler hakkında inceleme yapılmıştır. Elde edilen sonuçlar ışığında hazırladığımız ve yöneticilerin önerilerini de içeren ayrıntılı bir rapor, İzmir İl Milli Eğitim Müdürlüğü’ne İSG biriminin çalışmalarında rehberlik etmesi amacıyla sunulacaktır. Bu araştırmada “Tarama Modeli“ kullanılmıştır. Bu çalışmanın evrenini, 2020-2021 eğitim öğretim yılında İzmir' deki Milli Eğitim Bakanlığın’ a bağlı resmi ortaokullarda görev yapan 515 okul müdür oluşturmuştur. Verilerin toplanabilmesi için, hazırladığımız ölçekler elektronik ortamda ulaştırılmıştır. Ulaşan yanıtlar incelenerek, yanıtlanmamış/bazı soruları eksik yanıtlanmış olanlar kapsam dışı bırakılmıştır. Elde edilen 317 ölçeğin analizi “SPSS 24” programıyla yapılmıştır. Sorulara katılma seviyesini tespit etmek için betimleme betimsel istatistikler (yüzde, frekans, aritmetik ortalama, standart sapma), demografik değişkenlere (yaş, cinsiyet, çalışma yılı, yöneticilik tecrübesi) göre anlamlı farkın olup olmadığını belirlemek için t testi ve tek yönlü varyans analizi, İSG uygulamalarına yönelik algıları ile İSG uygulamalarını değerlendirme arasındaki ilişkiyi belirleyebilmek içinse korelasyon uygulanmıştır. p0,05 değeri istatiksel açıdan anlamlı kabul edilmiştir. Araştırma verilerinin çözümlenmesinde, verilerin analizler için uygun olup olmadığı kontrol edilmiştir. Verilerden elde edilen ortalamalara ilişkin normallik dağılımı kontrol edilmiştir.In this study, it was aimed to determine the perception levels, responsibilities and authorities of middle school principals in İzmir province towards occupational safety and quality management systems. With this study, in addition to those in the normal process, the problems created by the pandemic process and the methods applied/suggested by the managers were examined. A detailed report, which we have prepared in the light of the results obtained and including the suggestions of the administrators, will be submitted to the İzmir Provincial Directorate of National Education in order to guide the work of the OHS unit. In this research, "Scanning Model" was used. The universe of the research is 515 school principals working in official secondary schools affiliated to the Ministry of National Education in Izmir in the 2020-2021 academic year. The scales we prepared were delivered electronically in order to collect data. The received answers were examined and those that were not answered/some of the questions were incompletely answered were excluded. The analysis of the obtained 317 scales was made with the "SPSS 24" program. Descriptive statistics (percentage, frequency, arithmetic mean, standard deviation) to determine the level of participation in the questions, t test and one-way analysis of variance to determine whether there is a significant difference according to demographic variables (age, gender, working year, management experience), Correlation was applied to determine the relationship between perceptions about OHS practices and evaluating OHS practices. A p value of 0.05 was considered statistically significant. In analyzing the research data, the data were first tested in terms of suitability for analysis. The normality distribution for the means obtained from the data was tested

Preventive role of gallic acid on alcohol dependent and cysteine protease-mediated pancreas injury

In order to investigate an association between alcohol consumption and lysosomal cysteine protease induced pancreatic injury and preventive effect of gallic acid as dose-dependent, we determined myeloperoxidase and malondialdehyde levels, serum amylase activities and cathepsin B and L activities in the cytosolic and lysosomal fractions of pancreatic tissue in the ethanol (8 g/kg) and ethanol plus gallic acid (at different doses 50, 100 and 200 mg/kg) given rats. Absolute ethanol (8 g/kg) was given by oral gavage. Gallic acid was dissolved in the saline (2 ml/kg) and administered before 30 min the oral administration of ethanol. Pancreatic myeloperoxidase and also malondialdehyde levels and serum amylase activities were measured. Besides, histological investigations were made. Cathepsin B activities in the cytosolic fraction were decreased by gallic acid (200 mg/kg) and increased in ethanol given rats. Cytosolic/lysosomal ratio of cathepsin B and L were found to be low in the all doses of gallic acid as compared to ethanol group. Serum amylase, pancreatic myeloperoxidase activities and malondialdehyde levels in the ethanol group were higher than in the control group. These were not statistically significant for myeloperoxidase and malondialdehyde. Also, our histopathologic results indicated that ethanol administration increased pancreatic tissue injury. Gallic acid especially at 200 mg/kg improved ethanol-mediated pancreatic tissue damage.In conclusion, gallic acid treatments were decreased release of lysosomal cathepsin B and L enzymes into cytoplasmic fraction and prevented alcohol mediated pancreatic tissue injury. Preventive effect of gallic acid might be dose-dependent
