The Integration of Human Factors to Warehousing and Manual Order Picking Operations
Authors: Setayesh Azin
Published: August 2023

Human Factors (HF) identified as the main concern of studies since poor HF and system design interaction has a negative impact on quality, error occurrence, system performance, and worker’s well-being. This dissertation takes literature review and sensitivity analysis to assess human- system errors by focusing on: 1) finding the most suitable model to estimate human-system errors, 2) identifying failure modes causing human-system errors, 3) creating a tool that capable of identifying the source of pick errors and degraded quality at the initial stage of a design, 4) evaluating the usability, functionality, and usefulness of the developed tool. The most common Human Reliability Assessment (HRA) models were studied to identify the most suitable model to estimate human error probability (HEP) in various contexts. The qualitative and quantitative analysis among the most common HRA models showed that these models are suffering from lack of guideline on Performance Indicating Factors (PIFs) selection and multiplier values allocation. Hence, a need for creating and validating new empirically based models in different sectors were recognized. Therefore, the focus of the research study was changed from finding a suitable model to determining the source of errors in manual order picking operation. The developed Warehouse Design Error Prevention (WDEP) checklist tool integrated HF aspects to both Order Picking (OP) design elements and warehouse management elements based on the identified failure modes from literature and field studies as elaborated in chapter 3 of this dissertation. Tool usability, functionality, and usefulness were evaluated through the survey study and qualitative interviews. The outcome of the user evaluation found the created tool useful, functional, and useable both at the initial stage of a design as well as during process improvement process. These dissertation findings illustrate the need for developing HF measures that contribute to pick errors and optimize OP system design strategies concerning HF demands by creating and validating the error prevention checklist tool. 
Integrated Production, Quality and Inspection Optimization Models for Production Systems with Delayed Failure
Authors: Azimpoor Samareh
Published: August 2023

Businesses are expected to meet customers’ demands, including high-quality products and timely deliveries. However, in practice, production lines are subject to unforeseen events (i.e., failures), which affect production efficiency. Despite several attempts in the literature, there is still a need for models that can minimize those issues. This dissertation contains different optimization models that can help managers deal with various unexpected events and keep manufacturing firms competent and efficient.

In the first contribution (Chapter 2), the case of failures in a single machine production machine is considered. The machine’s failures are described using a two-stage delay time model. The model integrates the machine’s condition, inspection policy, and maintenance actions in a recursive equation to obtain the total expected makespan and production cost. The developed model helps managers reduce the number of failures and resource waste due to failure downtime.

In the second contribution (Chapter 3), we consider the possibility of performing minimal repair or replacement depending on the machine's age and investigate how the scheduling decisions are impacted accordingly. Several managerial insights are provided regarding the amount of investment in a maintenance operation depending on the machine's failure characteristics and inspection policy.

In Chapter 4, a parallel-machine scheduling problem is studied, in which decisions about inspection and production schedules are made based on the machines' stochastic failure process. The identical parallel machines are exposed to a two-stage delay time model (DTM). Due to the large-size configuration of the solution space for this problem, a branch and bound algorithm is used for optimization.

Finally, in Chapter 5, we use the direct effect of a machine's health condition as one of the significant factors that cause non-conforming products. The DTM is used as an opportunity to perform periodic quality inspections of the products and to detect a higher than acceptable level of non-conformity, which is an indicator of a defective machine. We formulate the effects of the machine's condition, inspection, and maintenance activities on the proportion of non-conforming products. Apart from product quality control, inspection is also used to assess the machine's condition and perform a maintenance action, if required.
Real-Time Optimization of Production Scheduling: Strategies, Models, and Algorithms
Authors: Ghaleb Mageed
Published: August 2023

In practice, manufacturing systems are highly dynamic and continuously facing unexpected events and interruptions. This puts production managers in charge of making frequent updates to the ongoing plans and schedules to cope with these changes. This is done by adopting different scheduling strategies and optimization models. Despite several attempts in the literature, the need for models that can minimize the effect of changes (i.e., stochastic and robust models) or react to them using real-time information (i.e., real- time optimization models) is still felt. 

This dissertation includes three main contributions with different optimization models and heuristic algorithms that can help managers deal with different unexpected events and interruptions on the shop floor. In the first contribution (Chapter 2), the case of stochastic deterioration-based failures in a single machine production system is considered. The machine’s degradation is modeled as a multi-state system. The obtained formulations are then integrated into an optimization model that jointly optimizes the production sequences, machine inspections, and condition-based maintenance actions. The results showed an average improvement of about 35% in total expected costs when information about the machine’s degradation level was used. 

In the second contribution (Chapter 3), the case of unexpected new job arrivals and random machine breakdowns in a flexible job shop production environment is considered. The effect of random machine breakdowns on the processing durations is formulated and then integrated into a dynamic optimization model. The proposed model investigates how real-time updates can be utilized to improve scheduling decisions based on unexpected arrivals, the availability of machines (downtimes and recovery times), and the completion times of operations. 

Finally, in Chapter 4, the case of integrating production scheduling and condition-based preventive maintenance (PM) planning in a flexible job shop production system is addressed. The study considers the case of stochastic machine degradation, random machine breakdowns, minimal repairs, condition-based PM, due date changes, and new job arrivals. The reliability of machines is modeled as a multi-state system, in which the obtained formulations are incorporated into an integrated dynamic optimization model. The developed model aims to study the effects of different RTS policies on each of the considered cases and empirically quantify the potential benefits of using real-time information to enhance scheduling decisions.

Open science skills are increasingly important for a career in ecology and evolution as efforts to make data and analyses publicly available and transparent continue to become more commonplace. However, open science skills are not typically taught in biology undergraduate programs. In learning core concepts in ecology and evolutionary biology (EEB), students must also gain skills in open science or they will miss out on opportunities to prepare for future careers. Core open science skills, like programming and practices that promote reproducibility and data sharing, can be taught to undergraduate students alongside core concepts in EEB. Yet, a major challenge in teaching open science skills and EEB concepts simultaneously is the high cognitive load associated with teaching multiple disparate concepts at the same time. One solution is to provide students with easily digestible, scaffolded, pre-formatted code in the form of vignettes and interactive tutorials. Here we present six open-source teaching tutorials for undergraduate students in EEB. These tutorials were developed through a graduate student based working group entitled Data Bytes in Ecology and Evolutionary Biology. These tutorials combine teaching data literacy and programming (using R) with analyzing publicly available data sets to teach fundamental ecological and evolutionary concepts and by doing so, introduce students to open science concepts and tools. Spanning a variety of EEB topics and skill levels, these tutorials serve as examples of how educators can integrate open science tools, programming, and data literacy into undergraduate teachings in topics of ecology and evolution.

Incidences of diseases treated with transplantation frequently peak at higher age. The contribution of age to total risk of transplantation has not been estimated amidst an aging society. We compare outcomes of 1,547 patients aged 70-79 years and 9,422 patients aged 60-69 years transplanted 1998-2018 for myeloid, lymphoid and further neoplasia in Germany. To quantify the contribution of population mortality to survival, we derive excess mortality based on a sex-, year- and agematched German population in a multistate model that incorporates relapse and graft-versus-host-disease (GvHD). Overall survival, relapse-free survival (RFS) and GvHD-free-relapse-free survival (GRFS) is inferior in patients aged 70-79 years, compared to patients aged 60-69 years, with 36% (95% Confidence Interval [CI]: 34-39%) versus 43% (41-44%), 32% (30- 35%) versus 36% (35-37%) and 23% (21-26%) versus 27% (26-28%) three years post-transplant (P<0.001). Cumulative incidences of relapse at three years are 27% (25-30%) for patients aged 70-79 versus 29% (29-30%) (60-69 years) (P=0.71), yet the difference in non-relapse mortality (NRM) (40% [38-43%] vs. 35% [34-36%] in patients aged 70-79 vs. 60-69 years) (P<0.001) translates into survival differences. Median OS of patients surviving >1 year relapse-free is 6.7 (median, 95% CI: 4.5-9.4, 70-79 years) versus 9 (8.4-10.1, 60-69 years) years since landmark. Three years after RFS of one year, excess NRM is 14% (95% CI: 12-18%) in patients aged 70-79 versus 12% [11-13%] in patients aged 60-69, while population NRM is 7% (6-7%) versus 3% (3-3%). Mortality for reasons other than relapse, GvHD, or age is as high as 27% (24-29%) and 22% (22-23%) four years after transplantation. In conclusion, survival amongst older patients is adequate after allogeneic stem cell transplantation.

Published: August 2023

Primary mediastinal B-cell lymphoma (PMBCL) is a distinct clinicopathologic entity. Currently, there is a paucity of randomized prospective data to inform on optimal front-line chemoimmunotherapy (CIT) and use of consolidative mediastinal radiation (RT). To assess if distinct CIT approaches are associated with disparate survival outcomes, we performed a systematic review and meta-analysis comparing dose-intensive (DI-CIT) versus standard CIT for the front-line treatment of PMBCL. Standard approach (S-CIT) was defined as R-CHOP-21/CHOP-21, with or without RT. DI-CIT were defined as regimens with increased frequency, dose, and/or number of systemic agents. We reviewed data on 4,068 patients (2,517 DI-CIT; 1,551 S-CIT) with a new diagnosis of PMBCL. Overall survival for DI-CIT patients was 88% (95% CI: 85-90) compared to 80% for the S-CIT cohort (95% CI: 74-85). Meta-regression revealed an 8% overall survival (OS) benefit for the DI-CIT group (P<0.01). Survival benefit was maintained when analyzing rituximab only regimens; OS was 91% (95% CI: 89-93) for the rituximab-DI-CIT arm compared to 86% (95% CI: 82-89) for the R-CHOP-21 arm (P=0.03). Importantly, 55% (95% CI: 43-65) of the S-CIT group received RT compared to 22% (95% CI: 15-31) of DI-CIT patients (meta-regression P<0.01). To our knowledge, this is the largest meta-analysis reporting efficacy outcomes for the front-line treatment of PMBCL. DI-CIT demonstrates a survival benefit, with significantly less radiation exposure, curtailing long-term toxicities associated with radiotherapy. As we await results of randomized prospective trials, our study supports the use of dose-intensive chemoimmunotherapy for the treatment of PMBCL.

While novel radioisotope therapies continue to advance cancer care, reports of therapy-related myeloid neoplasms (t-MN) have generated concern. The prevalence and role of clonal hematopoiesis (CH) in this process remain to be defined. We hypothesized that: (i) CH is prevalent in relapsed follicular lymphoma and is associated with t-MN transformation, and (ii) radiation in the form of radioimmunotherapy (RIT) plays a role in clonal progression. In this retrospective cohort study, we evaluated the prevalence and prognostic impact of CH on clinical outcomes in 58 heavily pre-treated follicular lymphoma patients who received RIT. Patients had been given a median of four lines of therapy before RIT. The prevalence of CH prior to RIT was 46%, while it was 67% (P=0.15) during the course of RIT and subsequent therapies in the paired samples. Fourteen (24%) patients developed t-MN. Patients with t-MN had a higher variant allele fraction (38% vs. 15%; P=0.02) and clonal complexity (P=0.03) than those without. The spectrum of CH differed from that in age-related CH, with a high prevalence of DNA damage repair and response pathway mutations, absence of spliceosome mutations, and a paucity of signaling mutations. While there were no clear clinical associations between RIT and t-MN, or overall survival, patients with t-MN had a higher mutant clonal burden, along with extensive chromosomal abnormalities (median survival, afer t-MN diagnosis, 0.9 months). The baseline prevalence of CH was high, with an increase in prevalence on exposure to RIT and subsequent therapies. The high rates of t-MN with marked clonal complexities and extensive chromosomal damage underscore the importance of better identifying and studying genotoxic stressors accentuated by therapeutic modalities.
Áttűnések és dilemmák egy múzeumtervezés kapcsán

Nem olyan régen egy új intézménnyel gyarapodott a magyarországi múzeumok sora, ráadásul kivételesen nem Budapesten – ahol egyébként szintén nem gyakori jelenség az ilyesmi –, hanem a túlméretes centrumtól távol, Nyíregyházán. A napi információs dömpingben elég nehezen ér el hozzánk egy ilyen hír, így a valódi jelentőségével még körülményesebb tisztában lenni. Pedig ez a múzeum bizonyos tekintetben világelső, hiszen a bizánci rítusú vallásos kultúra egyes elemeit őrző-bemutató intézmények léteznek ugyan, de a nyíregyházi – mint intézményi háttérrel rendelkező, dedikáltan görögkatolikus múzeum – egyedülálló a maga nemében.

Published: August 2023

Moringa, a multi-purpose and highly valued tree that possesses pharmacological properties which are widely used in medicine to treat a variety of diseases. The current study aimed to collect superior accessions from Bangladesh’s key moringa-growing regions through in-situ evaluation and document them by using morphological (qualitative and quantitative) traits and nutritional value in order to conserve the best indigenous landraces. Four major moringa growing regions in Bangladesh were selected namely, Chapai Nawabganj, Rangpur, Lalmonirhat and Rangamati. Twelve moringa accessions were collected during 2019-2020 based on the farmer’s preferences and morphological traits. The information on 35 quantitative and 16 qualitative aspects was analyzed using the International Plant Genetic Resource Institute (IPGRI), 2007 technique. The results demonstrated that flowering and fruiting occurred yearly in seasonal accession and three times per year in year-round accession. The flowers ranged in color from white to cream and year-round accession s MO8 and MO10 had corollas that were white with red spots. The seasonal accession’s MO1 exhibited the highest pods (97.22 g) weight, while the year-round accession’s MO12 had the lowest (45.16 g) pod weight. Leaves contained more than two times higher protein (23–34%) compared to pods (11–18%). As with nutrients, leaves had much higher levels of Ca and Fe (2137 to 3633 ppm and 252 to 424 ppm, respectively) than pods (2013 to 2875 ppm and 54- 69 ppm, respectively). Overall, the findings imply that there were numerous changes in the most important qualitative and quantitative traits as well as nutrients available in different parts of moringa. The information and analysis from these investigations could contribute to the genetic development of the species.

Published: August 2023

The use of banana leaf ash extract (BLAE) as a replacement of Kosaric medium (KM) to grow spirulina (Spirulina platensis) was investigated. KM was partially replaced with more affordable and locally available BLAE at 0, 10, 30, 50, and 70% concentrations. The spirulina was grown for 18 days at room temperature in the experimental media with artificial lighting and aeration. By replacing KM with BLAE, the 30% replacement produced the highest biomass of S. platensis. It was observed that replacing of KM by 30% with BLAE produced biomass of 1.22 g/L, which was similar to that of 1.33 g/L with control (P <0.05). However, replacing more than 50% KM by BLAE failed to promote growth relative to the control. Moreover, chlorophyll a concentrations in the control were found comparable in up to 30% of BLAE concentrations. Protein, lipid, and fiber contents of S. platensis were found to be 57.67 ± 0.58, 11.59 ± 0.28, and 7.35 ± 0.37%, respectively, in 30% replacement of KM, compared to corresponding values of 58.02 ± 1.16, 12.25 ± 0.39, and 7.53 ± 0.32%, respectively, in control KM. At the 50% KM replacement level, these values dropped to 52.65 ± 0.98, 9.97 ± 0.51, and 7.25 ± 0.29%, respectively. In conclusion, cultivation of S. platensis with BLAE up to 30% replacement of KM may be viable without undue effect on the plant’s growth, pigmentation, or biochemical makeup.

Information Technology Governance is currently widely implemented in companies. One of the domains that can be of concern is risk management. The application of TKTI in this domain can help companies identify, evaluate, reduce, and manage risks related to their business to achieve company goals better. In this case, three frameworks can be considered, including NIST, ISO 27001, and Octave, but implementing these frameworks only sometimes goes as planned. This study aims to identify the factors that cause the ineffectiveness of implementing Information Technology Governance (ITG) in the risk management domain using the NIST, ISO 27001, and Octave frameworks. Through an analysis of existing literature and data processing, this study found that factors such as lack of understanding of the framework, lack of adequate resources, and implementation challenges play an essential role in ineffectiveness. This study concludes by providing valuable insights for organizations seeking to strengthen their risk management capabilities.

Kaynaştırma eğitiminin kökenleri, 1960’larda ayrı özel eğitim sınıflarının etkinliğini sorgulayan özel eğitim araştırmalarına dayanmaktadır. Bu eğitim türü, 1994 yılında Salamanca Bildirisi ve Özel İhtiyaç Eğitiminde Eylem Çerçevesi'nde onaylanmış ve Birleşmiş Milletler (BM) ve UNESCO tarafından eğitim sistemleri için temel bir ilke olarak tanımlanmıştır. Kaynaştırma eğitimi kavramı, nispeten yeni bir araştırma alanı olmasına rağmen bu alanda yeterli ölçüde bilimsel çalışmaların üretildiği görülmektedir. Bu çalışmada, kaynaştırma eğitimi ve destek eğitim odaları alanında 1972-2022 yılları arasında Web of Science veri tabanında yer alan araştırmaları analiz etmek amaçlanmıştır. Bu çalışma, önceki araştırmalardan farklı olarak alandaki araştırma eğiliminin hangi yöne evrildiğini, araştırmacıların üretkenliklerinin yıllar itibariyle dağılımını, araştırmacıların güncel eğilimlerini de ortaya koymaktadır. 884 yayın, R Studio programı yardımıyla analiz edilmiş ve sonuç olarak, yıllık yayın üretim oranının %14,82 olduğu tespit edilmiştir. Ayrıca, “MESSIOU K”nın en fazla yayın yapan (11 yayın), en fazla atıf alan (171 atıf) ve aynı zamanda h ve g indeksi en yüksek olan araştırmacı olduğu belirlenmiştir. Son olarak, 2021 yılındaki araştırmalarda “attitudes” kelimesinin trend olduğu ve ilk kez model ve sistem (çerçeve) kelimelerinin ön plana çıktığı belirlenmiştir.

Bu araştırmanın amacı, okul yöneticilerinin algılarına göre okul müdür ve müdür yardımcıları arasındaki çatışma alanlarını, nedenlerini, etkilerini ve çözüm yollarını değerlendirmektir. Araştırmanın çalışma grubunu, Batman, Mardin ve Siirt illerindeki ilkokul, ortaokul ve liselerde görev yapan 18 okul müdürü ve 24 müdür yardımcısı oluşturmaktadır. Çalışma grubunun belirlenmesinde maksimum çeşitlilik örnekleme tekniği kullanılmıştır. Nitel araştırma olarak tasarlanan çalışmanın verileri yarı yapılandırılmış görüşme formu ile toplanmış, veriler içerik analizi yöntemi ile çözümlenmiştir. Araştırma bulgularına göre, okul müdür ve müdür yardımcıları arasındaki çatışmaların birden çok kaynağının olduğu, çatışma kaynakları konusunda okul müdür ve müdür yardımcılarının algılarının ayrıştığı ve yöneticilerin mesleki tecrübelerinin çatışmaların azaltılmasında önemli bir role sahip olduğu söylenebilir. Araştırma sonucuna göre, okul müdür ve müdür yardımcıları arasındaki çatışmalar okul kültür ve iklimini olumsuz etkilemekte ve okul başarısını düşürmektedir. Okul müdür ve müdür yardımcıları arasındaki çatışmaların yıkıcı etkisi göz önüne alındığında, çatışmaların azaltılmasına yönelik önlemler alınmasının yararlı olacağı düşünülmektedir.

Çalışmanın amacı döviz kurlarının ve milli gelir düzeylerinin, Türkiye’nin dış ticareti üzerindeki etkisini ortaya koymaktır. Döviz kurlarının reel efektif değerleri ve nominal değerleri ile Türkiyenin milli gelir düzeyi ile yabancı ülkelerin milli gelir düzeyinin, ihracat ve ithalat üzerindeki etkileri incelenmiştir. 1998:Q1-2022:Q2 dönemi için Fourier zaman serisi analizi yöntemiyle ele alınmıştır. Çalışmada Fourier yöntemlerinin kullanılmasının nedeni yumuşak geçişlere izin vermesidir. Serilerin durağanlığı; Fourier KPSS ve Fourier ADF birim kök testiyle incelenmiş, farklı düzeylerde durağanlığı bulunan değişkenlerin Fourier Toda Yamamoto nedensellik analizi ile ilişkilerin yönü ele alınmıştır. Nominal kurlardan, yurt içi milli gelire doğru tek yönlü bir nedensellik ilişkisi olduğu sonucuna ulaşılmıştır. Reel efektif döviz kurundan, ithalat ve ihracat arasında nedensellik ilişkisi bulunamamıştır. Esneklik katsayılarının hesaplanmasında reel efektif kur katsayısının istatistiksel olarak anlamsız olması nedeniyle değerlendirme yapılamamıştır. Fakat nominal kurun anlamlı olması esneklik katsayılarının Genişletilmiş Marshall-Lerner koşulunu sağladığı sonucuna ulaşılmıştır. İncelenen zaman aralığında nominal kurda meydana gelen değişimlere paralel olarak dış ticaret dengesinin bundan pozitif yönlü etkilendiği görülmektedir. Nominal döviz kurlarında görülen devalüasyonların ihracatı arttırıcı, ithalatı ise azaltıcı etkisi olmuştur. Yurtiçi milli gelir düzeyinin artması ithalat için talep oluşturmakta ve ithalatı arttırmaktadır. Yabancı ülkelerin milli gelir düzeyinde artışlar ise Türkiye’nin ihracatına olumlu etki etmektedir
FETÖ ve Aum Shinrikyo Örnekliğinde Ilımlı Dini Hareketten Terör Örgütüne Dönüşüm: Sistematik Bir Değerlendirme
Authors: GÜR Ali
Published: August 2023

Başlangıçta “ılımlı İslam” temsilcisi olarak lanse edilen bir hareketin çıktığı yoldan saparak uluslararası radikal bir terör örgütü olan Fetullahçı Terör Örgütüne (FETÖ) dönüşmesi, farklı coğrafyalarda ve başka dinlerde de bu tarz dönüşüm geçiren dini yapıların olup olmadığı sorusunu akla getirmektedir. Bu açıdan bakıldığında FETÖ gibi ılımlı dini hareket söylemiyle Budist inancının çağdaş hareketlerinden biri olarak kurulan ve Japon Devleti’nin korumasında olan Aum Shinrikyo’nun radikal terör örgütüne dönüşüm süreci FETÖ ile örtüşmektedir.
Çoklu açık kaynaklardan elde ettiğimiz verilerle dördü kuruluş tarihçesi, kırkı da örgütsel yapısı ile ilgili olmak üzere toplamda kırk dört başlık altında FETÖ’nün temel tanımlayıcı özellikleri belirlendi. Belirlenen bu özellikler çerçevesinde uluslararası iki terör örgütü olan FETÖ ile Aum Shinrikyo’nun benzerlik gösteren yönlerinin tablo halinde sistematik olarak analiz edilmesi ve tartışılması amaçlandı. Kapsamlı ve sistematik bir analizle tablo şeklinde kolay anlaşılabilir halde sunuşumuz çalışmamızın güçlü yönü olması yanı sıra iki örgütü karşılaştıran ilk kapsamlı analiz olması yönüyle de önem arz etmektedir.
Açık kaynaklardan veri madenciliği yapılarak elde edilen bulgular, farklı terörist örgütler tarafından kullanılabilmesi nedeniyle hangi din veya inanç olursa olsun dini kült yapıların benzer özellikler gösterebildiklerini, zamanla şiddet ve terör örgütüne dönüşen farklı coğrafyalar ve dinlerdeki kült örgütlerin motivasyon kaynaklarının benzerliklerinin dikkat çekici olduğunu ortaya koymuştur. Belirlenen kırk alt başlığın otuz üçünde FETÖ, Aum Shinrikyo ile benzerlik göstermiştir. Farklı coğrafyalarda ve farklı dinlerde birbirine yakın tarihlerde kurulan iki terör örgütünün böylesine birbirine benzemesi dikkat çekici olduğu gibi aynı zamanda belirli bir merkez tarafından da yönlendirildikleri yönünde fikir oluşturabilmektedir.
