Bunun gerçekleştirilebilmesi için Lojistik şirketerinin uygun bilişim teknolojileri ile desteklenmesi gerekmektedir. İnternet kullanımı ile müşteri ve lojistik sağlayıcı arasında etkili bir bilgi akışı ortamı sağlanmaktadır; ancak lojistik hizmetindeki bilgi ve ürün akışı arasındaki mevcut açıklık, sıcaklık duyarlı nesneler hakkında gerçek zamanlı bilginin elde edilmesinde karar vericiler için lojistik yönetimini daha zor duruma getiren bir problem oluşturmaktadır. Nesnelerin İnterneti alanındaki gelişmeler soğuk zincir sanayilerinde izleme, yönetme ve gerçek zamanlı görünürlük sağlama ve uygun zeka seviyesi ile bilgi paylaşımı alanında potensiyel çözümler sunmaktadır. Bu çalışmada soğuk zincirin gerçek zamanlı ortam sıcaklığını izleme, yönetme ve soğuk zincir içerisindeki sıcaklık duyarlı ürünlerin raf ömrünün tahmin edilmesi aracılığıyla tüm karar vericilerin karar desteklerini geliştirmeye yardımcı olan IoT erişimli soğuk zincir lojistiği gösterilemektedir. Çalışma içerisinde, gerçek zamanlı ortam verileri IEEE 802.15.4 kablosuz algılayıcı ağ yapısı kullanılarak elde edilmiş ve toplanan veriler bir ağ geçidi aracılığıyla sunucuya, ürünlerin raf ömürlerinin geliştirilen karar destek sistemi yardıyla tahmin edilebilmesini sağlamak üzere, gönderilmiştir. Ayrıca, soğuk zincir içerisindeki bozulabilir ürünlerin tespiti için Radyo Frekanslı Tanıma (Radio Frequency Identification-RFID) kullanılmıştır. Çalışma içerisinde kullanılan tüm cihazlar ve protokoller olay-güdümlü Riverbed Modeler yazılımıyla modellenerek benzetimleri yapılmıştır.The Dramatic growth of world economy results growth in the supply chain which demands logistics service to be agile, flexible and responsive in the face of uncertainty, especially for temperature sensitive products that need to be monitored and managed in the cold chain. To achieve this, Logistics companies must be supported by appropriate information technologies. Internet provides an effective means of driving information between customer and logistics provider, however, existing gap between products flow and information flow in logistic service has created a problem in getting real-time information about temperature sensitive items which make logistics management more challenging for decision makers. The growth of internet of things (IoT) gives a potential solution for monitoring, managing, and achieving real-time visibility and sharing information with the appropriate level of intelligence in cold chain industries. This paper demonstrates IoT enabled cold chain logistics that helps to enhance the decision support of all actors through managing, monitoring the real-time ambient temperature of the cold chain and predicting the shelf-life of temperature sensitive products inside the cold chain. In the study, real-time data of ambient parameters are gathered using IEEE 802.15.4 based wireless sensor networks and sent to the remote server through a gateway so that the shelf life of the products can be predicted by the decision support system developed. Radio Frequency Identification (RFID) is also used for identification of perishable goods inside the cold chain. All the devices and protocols employed in the study are modeled and simulated using event-driven Riverbed Modeler software

Indonesia stopped sending Indonesian migrant workers (PMI) to Malaysia after the establishment of the Online Maid System (SMO) by the Malaysian government. SMO created various issues for PMI, especially in protecting their rights. A qualitative method was used in this study. This study discusses various factors that underlying Indonesia's foreign policy to freeze on sending PMI to Malaysia in 2022 after the establishment of the Online Maid System (SMO) by the Malaysian Government. This foreign policy analysis used funnel of causality theory from Eugene Wittkopf. This study results showed that domestic and international factors influenced in formalizing foreign policy. Domestic factors affected Indonesia's foreign policy to freeze on sending of PMI to Malaysia in 2022 after the establishment of the Online Maid System (SMO) by the Malaysian Government, including the Indonesian government's policy regarding regulation and protection of the migrant workers rights. Similarly, the role and influence of community and human rights activists in Indonesia who struggled the rights and interests of Indonesian migrant workers. The international factors, including global human rights issues for Indonesian Migrant Workers, Malaysia's policy in implementing the Online Maid System and bilateral relations between Indonesia and Malaysia related in sending PMI to Malaysia

Securitisation of Ukrainian Critical Infrastructures: The Case of the Failure of SCADA System in Protecting the Power Grids

Critical infrastructures are the important element to support the social cohesion in a certain area. Therefore, it is necessary to protect critical infrastructures in order to maintain the sustainability of the assets. There are many attempts of states to control the security of their critical infrastructures, one of them is using Supervisory Control and Data Acquisition (SCADA) system, a control system in which to monitor and retrieve data under the supervision of an operator. However, although countries are aware of the preventive action over their critical infrastructures, it is still possible to fail. In this case, Ukraine which has a relatively secure control system was failed in protecting its power grids from multiple hacker attacks which contributed to blackouts in December 2015. The devastating failure of Ukraine’s security system has led public opinion to point a finger to Russia since the relationship of both countries is at stake. In this sense, Ukraine issued a speech act to securitise its critical infrastructures. By exercising securitisation theory, this article would discuss further about the fruitfulness of the speech act after the failure of the security system in protecting Ukraine’s power grids.

Analisis Reflektif pada Pendekatan Neo-institusional dalam Memahami ASEAN sebagai Organisasi Kontraterorisme di regional Asia Tenggara

Stabilitas regional Asia Tenggara diuji tidak hanya oleh persaingan Kekuatan Besar global di kawasan ini, tetapi juga oleh berkembangnya kejahatan lintas batas yang berubah, yaitu jaringan terorisme terorganisir. Dalam perspektif Studi Keamanan, dapat dipahami bahwa hambatan-hambatan regional ini dapat berwujud dalam tindakan ekstrem yang dapat lebih mengancam stabilitas keamanan kawasan. Menangani dan mengelola kejahatan lintas batas sulit untuk ditangani secara independen; oleh karena itu, negara-negara anggota ASEAN di kawasan Asia Tenggara bergabung dan membentuk mekanisme keamanan regional melalui ASEAN sebagai sarana kerja sama regional dalam menekan ancaman lintas batas. Namun, banyak studi akademik dalam dekade terakhir masih menilai ASEAN sebagai organisasi keamanan internasional yang cacat, meskipun memiliki prinsip-prinsip dasar dengan pendekatan kolaboratif dalam tugasnya untuk menekan kejahatan terorganisir lintas batas di kawasan ini. Artikel ini berargumen bahwa kesimpulan ini disebabkan oleh sudut pandang dalam menilai efektivitas ASEAN melalui pendekatan neo-institusionalisme. Dengan kata lain, makalah ini berargumen bahwa mengukur efektivitas sebuah institusi berdasarkan keterbatasan dan kepatuhan terhadap aturan-aturan formal atau informalnya diyakini kurang kontekstual untuk mengevaluasi ASEAN dan mekanismenya dalam menghadapi kejahatan terorganisir lintas batas di tingkat regional. Secara keseluruhan, pendekatan neo-institusionalisme tidak sepenuhnya memperhatikan kepentingan politik domestik negara anggota ASEAN sebagai salah satu dari banyak elemen penting dalam pengembangan mekanisme ASEAN dalam menangani kejahatan lintas batas

Prospective observational cohort study on grading the severity of postoperative complications in global surgery research

Background The Clavien–Dindo classification is perhaps the most widely used approach for reporting postoperative complications in clinical trials. This system classifies complication severity by the treatment provided. However, it is unclear whether the Clavien–Dindo system can be used internationally in studies across differing healthcare systems in high- (HICs) and low- and middle-income countries (LMICs). Methods This was a secondary analysis of the International Surgical Outcomes Study (ISOS), a prospective observational cohort study of elective surgery in adults. Data collection occurred over a 7-day period. Severity of complications was graded using Clavien–Dindo and the simpler ISOS grading (mild, moderate or severe, based on guided investigator judgement). Severity grading was compared using the intraclass correlation coefficient (ICC). Data are presented as frequencies and ICC values (with 95 per cent c.i.). The analysis was stratified by income status of the country, comparing HICs with LMICs. Results A total of 44 814 patients were recruited from 474 hospitals in 27 countries (19 HICs and 8 LMICs). Some 7508 patients (16·8 per cent) experienced at least one postoperative complication, equivalent to 11 664 complications in total. Using the ISOS classification, 5504 of 11 664 complications (47·2 per cent) were graded as mild, 4244 (36·4 per cent) as moderate and 1916 (16·4 per cent) as severe. Using Clavien–Dindo, 6781 of 11 664 complications (58·1 per cent) were graded as I or II, 1740 (14·9 per cent) as III, 2408 (20·6 per cent) as IV and 735 (6·3 per cent) as V. Agreement between classification systems was poor overall (ICC 0·41, 95 per cent c.i. 0·20 to 0·55), and in LMICs (ICC 0·23, 0·05 to 0·38) and HICs (ICC 0·46, 0·25 to 0·59). Conclusion Caution is recommended when using a treatment approach to grade complications in global surgery studies, as this may introduce bias unintentionally

The surgical safety checklist and patient outcomes after surgery: a prospective observational cohort study, systematic review and meta-analysis

© 2017 British Journal of Anaesthesia Background: The surgical safety checklist is widely used to improve the quality of perioperative care. However, clinicians continue to debate the clinical effectiveness of this tool. Methods: Prospective analysis of data from the International Surgical Outcomes Study (ISOS), an international observational study of elective in-patient surgery, accompanied by a systematic review and meta-analysis of published literature. The exposure was surgical safety checklist use. The primary outcome was in-hospital mortality and the secondary outcome was postoperative complications. In the ISOS cohort, a multivariable multi-level generalized linear model was used to test associations. To further contextualise these findings, we included the results from the ISOS cohort in a meta-analysis. Results are reported as odds ratios (OR) with 95% confidence intervals. Results: We included 44 814 patients from 497 hospitals in 27 countries in the ISOS analysis. There were 40 245 (89.8%) patients exposed to the checklist, whilst 7508 (16.8%) sustained ≥1 postoperative complications and 207 (0.5%) died before hospital discharge. Checklist exposure was associated with reduced mortality [odds ratio (OR) 0.49 (0.32–0.77); P\u3c0.01], but no difference in complication rates [OR 1.02 (0.88–1.19); P=0.75]. In a systematic review, we screened 3732 records and identified 11 eligible studies of 453 292 patients including the ISOS cohort. Checklist exposure was associated with both reduced postoperative mortality [OR 0.75 (0.62–0.92); P\u3c0.01; I2=87%] and reduced complication rates [OR 0.73 (0.61–0.88); P\u3c0.01; I2=89%). Conclusions: Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine
