Published: March 2021

ABSTRAKDesain breakwater pada pembangunan Pelabuhan Tanjung Adikarto telah beberapa kali mengalami perubahan sejak tahun 2003. Pelaksanaan konstruksi breakwater sisi barat dan sisi timur pada tahun 2007 dan 2008 mengalami kegagalan akibat gelombang tinggi dari Samudera Hindia yang dianggap merusak. Desain review dengan sudut breakwater yang bergeser untuk membuka jalur navigasi dibuat pada tahun 2011 dan proses konstruksinya terhenti pada tahun 2012. Desain tinjauan ketiga dibuat pada tahun 2013 namun hingga saat ini konstruksinya belum dimulai. Berdasarkan laporan Proyek Yogya yang disupervisi oleh TU Delft, diketahui bahwa belum pernah dilakukan penelitian mengenai kondisi hidrodinamika untuk perencanaan pelabuhan. Pada penelitian ini, pemodelan hidrodinamika dan pemodelan transformasi gelombang dilakukan dengan tujuan untuk mengkaji karakteristik gelombang di sekitar breakwater. Pemodelan dilakukan untuk skenario desain tahun 2011 dan desain tahun 2013. Simulasi dilakukan pada bulan bulan Januari (musim barat) dan bulan Juli (musim timur) selama 30 hari guna mengetahui efektifitas dari breakwater dalam meredam gelombang.Kata kunci: breakwater, pemodelan, hidrodinamika, gelombang. ABSTRACTSince 2003, the breakwater design in the development planning for the Tanjung Adikarto Port has changed several times. The construction of the west and east side breakwaters in 2007 and 2008 failed due to high waves from the Indian Ocean which were considered destructive. A review design with a shifted breakwater angle to open the navigation chanel was made in 2011 and the construction also stopped in 2012. The third review design was made in 2013 but the construction has yet to begin. Based on the Yogya Project report supervised by TU Delft, it is known that hydrodynamic conditions have never been assessed for port planning. In this study, hydrodynamic and wave transformation modeling were carried out in order to study the characteristics of the waves around the breakwater. Modeling was carried out for the 2011 design scenario and also for 2013 review design scenario to determine the effectiveness of the breakwater in reducing waves.Keywords: breakwater, modeling, hydrodynamics, wave.

Published: March 2021

In these research notes, we present the results of a roundtable and a subsequent process of reflection on the challenges facing researchers in disability studies using creative methods. The roundtable took place at a conference on disability, “Diversity & Belonging: Celebrating Difference” in Athens in 2018. The aim of the roundtable was to explore with other researchers in disability studies the challenges and joys of academic research using creative research methods. Even though the commitment to inclusive research is common in disability studies, the use of creative research methods still feels like pioneering and unconventional. The purpose of the roundtable was to discuss how we can extend the use of creative research methods so that more people can join in research work. In these research notes, we discuss some reflections on the material that came out of our roundtable and from the reflective session we held after the roundtable. From studying these conversations, we identified four insights on the use of creative methods in disability studies: embodiment, discomfort, connection and plurality of voices.

Samenvatting
In deze research notes presenteren we de resultaten van een roundtable en het daaropvolgend proces van reflectie over de uitdagingen van het toepassen van creatieve onderzoeksmethoden in disability studies. De roundtable vond plaats op het disability-gerelateerd congres “Diversity & Belonging: Celebrating Difference” in Athene, 2018. Het doel van de roundtable was om samen met andere onderzoekers in disability studies de obstakels en kansen van creatieve onderzoeksmethoden in academisch onderzoek te verkennen. Hoewel onderzoek steeds meer inclusief vormgegeven wordt voelt het gebruik van creatieve methodes nog steeds aan als pionieren, baanbrekend en onconventioneel. Het doel van de roundtable was om met andere onderzoekers samen te exploreren hoe we het gebruik van creatieve onderzoeksmethoden kunnen uitbreiden zodat meer mensen kunnen meedoen in onderzoek. In het artikel gaan we in op de resultaten van de roundtable en ons reflectieproces daarna. Door deze gesprekken te bestuderen, identificeerden we vier inzichten over het gebruik van creatieve methoden in disability studies onderzoek: rond embodiment, ongemak, verbinding en meervoudigheid van stemmen.

An econometric analysis for food security in Tunisia
Authors: JEDER Houcine , Hattab Sabrine , Frija Iheb 
Published: March 2021

Food security issue is getting more attention in middle-income countries such as Tunisia after the revolution 2011, where many factors affecting its food security are multiplied. An econometric analysis of food security was done through the Vector Error Correction Model approach (VECM). The result of this approach shows that there is a significant long-term causality between the dependent variables and the explanatory variables. Some signs of variables like land under cereals assert the hypothesis of Ricardo’s land rent theory and also attract attention for the preservation of land fertility in climate change context. However, there is a short-term causal relationship between food security and independents variables like: land under cereals, inflation and food imports. These results confirm that the issue of food security in Tunisia is a question of threat in the short and long-term instability. So, it is important today to readjust some factors to ensure food security in Tunisia like controlling inflation and lowering the food importation as short-term measures and preserving and improving the fertility of land under cereals and adopting climate change as long-term measures.

Przyroda południowoafrykańska w relacjach Polaków (XVI-XX wiek)
Authors: Żukowski Arkadiusz 
Published: March 2021

Ukazano relacje Polaków dotyczące przyrody południowoafrykańskiej z perspektywy ponad 400 lat. Afryka Południowa, praktycznie do naszych czasów, jawiła się im zawsze jako kraj nie tylko bardzo odległy, ale też egzotyczny i interesujący. Determinowało to w poważnym stopniu charakter relacji. Podkreślały one przede wszystkim różnorodność i bogactwo przyrody południowoafrykańskiej. Przyrodę południowoafrykańską postrzegano również przez pryzmat wielkich możliwości łowieckich. Wielu Polaków odwiedzających Afrykę Południową wyrażało zdziwienie z obecności w tym kraju dwóch wykluczających się w zasadzie światów – nietkniętej przyrody i cywilizacji europejskiej.
Najczęściej opisywanym miejscem Afryki Południowej był Przylądek Dobrej Nadziei oraz okolice dzisiejszego Kapsztadu. Pierwszego dokładnego zapisu interior dokonał Antoni Rehman w latach siedemdziesiątych XIX wieku. Rzeczowo i ze znawstwem pisali o przyrodzie południowoafrykańskiej polscy uczeni, którzy uczestniczyli w XV Międzynarodowym Kongresie Geologicznym w Pretorii w 1929 roku: Walery Goetel, Jan Lewiński, Józef Morozewicz i Jerzy Loth. Dość liczne relacje odnośnie przyrody południowoafrykańskiej pojawiły się współcześnie w kontekście złożonej sytuacji społeczno- politycznej Afryki Południowej.
Continuous in-home walking speed monitoring in older people with a low-cost ambient sensor: Results of a feasibility study
Authors: Joddrell Phil , Potter Stephen , de Witte Luc P. , Hawley Mark S. 
Published: March 2021

BACKGROUND: Walking speed predicts important clinical outcomes in older adults and is one of the most significant indicators of frailty. OBJECTIVE: To test whether it is feasible to measure walking speed frequently and unobtrusively in the home. METHODS: A longitudinal feasibility study was conducted comprising the installation and monitoring of continuous measurement walking speed sensors in twenty frail older adults’ homes for a period of twelve weeks (eighteen participants completed the study). Manual walking speed, frailty level and health status were measured at four-weekly intervals. Qualitative interviews were conducted at the end of the study to assess participants’ attitudes to the sensors and to the concept of continuous in-home walking speed measurement. RESULTS: There was a high degree of variance to the number of walking speed measurements recorded by each participant’s sensor (median 1942.39, range 2-3617). Participants indicated acceptability of both the sensor within the home and the concept of in-home walking speed measurement. CONCLUSIONS: Where regular measurement was achieved, the results indicate that walking speed might be better viewed as a distribution rather than a single figure, taking into account the natural variation to walking speed in daily life. This study demonstrates the feasibility of continuous ambient in-home walking speed monitoring of older adults with a low-cost, easily deployed device.

Published: March 2021

OBJECTIVE: To explore the potential value of quantitative parameters derived from dual-energy spectral computed tomography (DESCT) as comparing to the parameters derived from magnetic resonance imaging (MRI) in detecting bone marrow (BM) infiltration and distinguishing different patterns of BM infiltration in patients diagnosed with Multiple myeloma (MM). METHODS: This study involved 35MM patients and 15 healthy control subjects who had undergone spinal DESCT and MRI. Pattern assignment was based on visual assessment of MR images, and the regions of interest were defined on both DESCT and apparent diffusion coefficient maps. Quantitative values of DESCT parameters were measured and compared between infiltrated and healthy bone marrow. Receiver operating characteristic (ROC) analysis was performed to determine potential utility of DESCT parameters in identifying BM infiltration and different patterns defined by MRI. Sensitivity and specificity under the optimal thresholds determined by the Youden Index were also calculated. RSULTS: Statistical differences were observed between the DESCT parameters including Ca(Water), Water(Ca), HAP(Fat), Fat(HAP) and Effective atomic number (Eff-Z) but not for the 70-keV CT value between the infiltrated and healthy BM (all P < 0.001). The 70keV CT value and Ca(Water), HAP(Fat) and Eff-Z values were also found to be statistically different in comparing different infiltration patterns (all P < 0.05). Performance of the model-based parameter Ca/Water was superior in differentiating between infiltrated and healthy BM in which the area under ROC curve, AUC = 0.856 [95% CI, 81.4–89.1%] with sensitivity = 0.841 and specificity = 0.768, as well as between MM patients and control subjects (AUC = 0.910 [95% CI, 79.5–97.3%], sensitivity = 0.829 and specificity = 1.000). CONCLUSIONS: Analysis of DESCT offers potential as a quantitative method to detect infiltrated BM and evaluate infiltration patterns of BM in patients diagnosed with MM.
