Governing Indonesia’s Secondary Education System: Challenges and Opportunities for Improvement in the Province of Yogyakarta
Authors: Sugiana Astrid Meilasari , Jumintono Jumintono
Published: August 2021

This paper focuses on government policies for improving secondary education in decentralized Indonesia. The research combines policy evaluation in the field of education through mixed methods, namely the top down method measuring the effectiveness of Indonesia’s policy reforms in numerical terms and the bottom up ethno-methodological approach incorporating soft system methodology for complementing policy evaluation. Data analysis was done by examining the distribution of narratives provided by the respondents and carrying out a thematic analysis in which emerging themes were used to produce a complex and coherent narrative of the discourse emerging from the case study site in Yogyakarta Province, Indonesia. The education system in modern Indonesia is marked by the tension between the centralized policy strategy of the Suharto period and the reactive strategy of Post-Suharto decentralization. During his current administration, President Joko Widodo promulgated education policies focusing on basic education reforms in five major areas, namely (i) facilitating the expansion of education facilities across Indonesia through the public and private sector (expansion of facilities and infrastructure in terms of quantity and quality), (ii) making basic education more affordable and accessible across regions and social-economic indicators (accessibility), (iii) improving the quality of educators, service and outputs in basic education (quality), (iv) increasing the relevance of basic education to the demands of tertiary education, the labor market and local economic development (relevance), and (v) good governance and accountability of Indonesia’s basic education system (accountability and public responsiveness). In conjunction with the government and the market in education, indigenous social and political groups have played significant roles in developing the secondary education system in Indonesia. Moreover, these groups have also improved pupils’ performance and pupils’ learning outcomes by improving the extent and quality of the services they provide in comparison to those provided by public schools run by the government. Individualized services which cater to the needs, backgrounds and interests of the consumers have had profound impacts on enrollment, retention, motivation and pupils’ character, knowledge, technical competence and competitiveness. This makes the education system more engaging, empowering and inclusive while taking into account its comprehensiveness. This also aids in promoting learning communities for complementing the government induced education system, for protecting children and for providing a holistic and integrated education services.
In silico studies of isatinyl-2-aminobenzoylhydrazone transition metal complexes against cyclin-dependent kinase 6 (CDK6)
Authors: Nusantoro Yesaya Reformyada , Fadlan Arif
Published: August 2021

Cyclin-dependent kinase 6 (CDK6) is an important member of protein kinases, involving in many cellular pathways especialy cell cycle progression. Thus, CDK6 is a promising target in cancer therapy. This report aims to predict inhibiton of CDK6 by some complex compounds by using molecular docking and pharmacological properties analysis. Those compounds are isatinyl-2-aminobenzoylhydrazone (ISABH) and cobalt (II), nickel (II), copper (II), and zinc (II) transition metal complexes. The molecular docking against CDK6 (PDB code: 3NUP) revealed that ISABH/ISABH-transition metal complexes established ligand-protein interaction as expressed by negative binding affinity values. Drug-likeness by SwissADME indicated that ISABH and Ni-ISABH met the Lipinski’s rule of five. Both compounds also showed reasonable pharmacological criteria by admetSAR.
EDUCATION INNOVATION MODEL WITH STRATEGY IMPLEMENTATION OF THE "DARE TO BE DIFFERENT" CONCEPT
Authors: Yusuf Muhammad , Syarifah Iip , Wahyudin Uyu
Published: August 2021

In the face of rapid and complex and unpredictable changes in life, educational innovation must be an important and critical priority because education is still the main support for improving the quality of human resources. The educational innovation model in the Indonesian Ministry of Education and Culture still tends to be more dominant in using a “top-down model” strategy, namely educational innovation developed from above by policy makers from the central level, to be implemented imperatively down to the lowest level of educational institutions. This will dull the creativity of the teaching staff and education staff. Thus, educational innovation should be balanced with a "bottom-up model" strategy, namely a model of educational innovation developed from below, which originates from the creativity of education personnel and educational staff in each educational institution implemented as an effort to improve the quality of education delivery. In order for educational innovation to run faster than other changes, it is necessary to look for more powerful models and strategies through various scientific approaches. The educational innovation model with a strategy of implementing the concept of "Dare to be different" is a concept used to motivate education providers to carry out educational innovations by not contradicting existing educational innovation models and strategies. This model focuses more on internalizing the enthusiasm for educational innovation, especially by educators. Dare to be different means daring to be different, so start with the word dare which stands for the words dream, attitude, relationship, and excellence.

Abstract

Coronaviruses are a large family of viruses that cause illness ranging from mild to severe symptoms. The increase in the number of COVID-19 cases is happening fast enough and there has been a spread between countries. Based on scientific evidence, COVID-19 can be transmitted from human to human through droplets, not through the air. Standard recommendations for preventing the spread of infection are regular hand washing with soap and clean water, practicing coughing and sneezing, avoiding direct contact with livestock and wild animals and avoiding close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing. This community service is in the form of counseling that aims to provide correct information and knowledge about COVID-19, its transmission and prevention to students at Santa Maria Medan Private High School so it is hoped that it will help in breaking the chain of COVID-19 transmission which is increasingly rampant.

The effect of forced change and unforced variability in heat waves, temperature extremes, and associated population risk in a CO2-warmed world
Authors: Lee Jangho , Mast Jeffrey C. , Dessler Andrew E.
Published: August 2021

Abstract. This study investigates the impact of global warming on heat and humidity
extremes by analyzing 6 h output from 28 members of the Max Planck
Institute Grand Ensemble driven by forcing from a 1 % yr−1 CO2 increase. We find that unforced variability drives large changes in regional exposure to extremes in different ensemble members, and these variations are mostly associated with El Niño–Southern Oscillation (ENSO) variability. However, while the unforced variability in the climate can alter the occurrence of extremes regionally, variability within the ensemble decreases significantly as one looks at larger regions or at a global population perspective. This means that, for metrics of extreme heat and humidity analyzed here, forced variability in the climate is more important than the unforced variability at global scales. Lastly, we found that most heat wave metrics will increase significantly between 1.5 and 2.0 ∘C, and that low gross domestic product (GDP) regions show significantly higher risks of facing extreme heat events compared to high GDP regions. Considering the limited economic adaptability of the population to heat extremes, this reinforces the idea that the most severe impacts of climate change may fall mostly on those least capable of adapting.
Comment on “Review of experimental studies of secondary ice production” by Korolev and Leisner (2020)
Authors: Phillips Vaughan T. J. , Yano Jun-Ichi , Deshmukh Akash , Waman Deepak
Published: August 2021

Abstract. This is a comment on the review by Korolev and Leisner (2020, hereafter KL2020). The only two laboratory/field studies ever to measure the breakup in ice–ice collisions for in-cloud conditions were negatively criticised by KL2020, as were our subsequent theoretical and modelling studies informed by both studies. First, hypothetically, even without any further laboratory experiments, such theoretical and modelling studies would continue to be possible, based on classical mechanics and statistical physics. They are not sensitive to the accuracy of lab data for typical situations, partly because the nonlinear explosive growth of ice concentrations continues until some maximum concentration is reached. To a degree, the same final concentration is expected regardless of the fragment
number per collision. Second, there is no evidence that both lab/field
observational studies characterising fragmentation in ice–ice collisions are either mutually conflicting or erroneous such that they cannot be used to represent this breakup in numerical models, contrary to the review. The fact that the ice spheres of one experiment were hail sized (2 cm) is not a problem if a universal theoretical formulation, such as ours, with fundamental dependencies, is informed by it. Although both lab/field studies involved head-on collisions, rotational kinetic energy for all collisions generally is only a small fraction of the initial collision kinetic energy (CKE) anyway. Although both lab/field experiments involved fixed targets, that is not a problem since the fixing of the target is represented via CKE in any energy-based formulation such as ours. Finally, scaling analysis suggests that the breakup of ice during sublimation can make a significant contribution to ice enhancement in clouds, again contrary to the impression given by the review.
Satellite retrieval of cloud base height and geometric thickness of low-level cloud based on CALIPSO
Authors: Lu Xin , Mao Feiyue , Rosenfeld Daniel , Zhu Yannian , Pan Zengxin , Gong Wei
Published: August 2021

Abstract. Satellite-based cloud base and top height (CBH and CTH) and cloud geometrical thickness (CGT) are validated against ground-based lidar
measurements and provide new scientific insights. The satellite measurements
are done by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite
Observation (CALIPSO). The retrieval methodology is built on the 333 m
resolution low-level water cloud data obtained from the Vertical Feature
Mask product of CALIPSO. The methodology is based on the definition that CBH
of boundary layer clouds is the lowest cloud base over an area of several
tens of kilometers. This allows taking the CBH of the neighboring penetrable
shallower cloud as having CBH representative for the entire cloud field. The
methodology over the ocean was validated based on observations from two
surface-based ceilometer measurements in the islands of Barbados and the
Azores, with an error standard deviation of ±115 m. Validation over
land was based on 4 years data of 138 terrestrial ceilometer sites with an
error standard deviation of ±220 m. The unprecedented accurate CBH
allows us to obtain CGT, which is an essential parameter in the
understanding of the aerosol–cloud interaction. Based on this newly
developed methodology, we retrieved the annual, seasonal, and diurnal
distributions of global CBH, CTH, and CGT for two years and analyzed the
variations of CBH and CTH over the ocean and land. Climatology of the annual
mean cloud geometrical properties shows the following. (1) The lowest CBH occurs over
the eastern margins of the subtropical oceans and increases westward from
300–400 to 800–900 m. The CGT increases from 300 to 1200 m, respectively. In
the western part of the tropical oceans, CBH is 500–600 m and CGT is
∼ 1500 m. (2) A narrow band of lower CBH and CGT occurs over
the Equator, especially over the eastern parts of the oceans. (3) CBH and
CGT over the tropical rain forests (Amazon and Congo) are 1200 and 1500 m,
respectively. CBH over the drier tropical land is 1500–2000 m, with CGT of 800–1000 m.
(4) CBH decreases towards Antarctica in the Southern Ocean, while CGT deepens. (5) Seasonally, the mid-latitude global oceans have the lowest CBH (mostly below 500 m) and CGT in summer seasons and the highest values in winter. (6) There is just an obvious difference between day and night for the maximum CTH and CGT over the tropics. Over the ocean, there is no discernible difference in CBH, but during night CTH is higher by ∼ 300 m.
Reconstructing Antarctic winter sea-ice extent during Marine Isotope Stage 5e

Published: August 2021

Abstract. Environmental conditions during Marine Isotope Stage (MIS) 5e (130–116 ka) represent an important ‘process analogue’ for understanding the climatic responses to present and future anthropogenic warming. The response of Antarctic sea ice to global warming is particularly uncertain due to the short length of the observational record. Reconstructing Antarctic winter sea-ice extent during MIS 5e therefore provides insights into the temporal and spatial patterns of sea-ice change under warmer than present climate. This study presents new MIS 5e records from nine marine sediment cores located south of the Antarctic Polar Front, between 55 and 70° S. We investigate changes in winter sea-ice extent and sea-surface temperatures between the three Southern Ocean sectors. The Atlantic and Indian sector records have much more variable MIS 5e winter sea-ice extent and sea-surface temperatures than the Pacific sector records. High variability in the Atlantic sector winter sea-ice extent is attributed to high glacial meltwater flux in the Weddell Sea while high variability in the Indian sector winter sea-ice extent results from large latitudinal migrations of the flow bands of the Antarctic Circumpolar Current. Overall, these findings suggest that Pacific sector winter sea ice displays a low sensitivity to warmer climates. The different variability and sensitivity of Antarctic winter sea-ice extent in the three Southern Ocean sectors during MIS 5e may have significant implications for the Southern Hemisphere climatic system under future warming.
EOT20: a global ocean tide model from multi-mission satellite altimetry
Authors: Hart-Davis Michael G. , Piccioni Gaia , Dettmering Denise , Schwatke Christian , Passaro Marcello , Seitz Florian
Published: August 2021

Abstract. EOT20 is the latest in a series of empirical ocean tide (EOT) models derived using residual tidal analysis of multi-mission satellite altimetry at
DGFI-TUM. The amplitudes and phases of 17 tidal constituents are provided on a global 0.125∘ grid based on empirical analysis of
seven satellite altimetry missions and four extended missions. The EOT20 model shows significant improvements compared to the previous iteration of
the global model (EOT11a) throughout the ocean, particularly in the coastal and shelf regions, due to the inclusion of more recent satellite
altimetry data as well as more missions, the use of the updated FES2014 tidal model as a reference to estimated residual signals, the inclusion of
the ALES retracker and improved coastal representation. In the validation of EOT20 using tide gauges and ocean bottom pressure data, these
improvements in the model compared to EOT11a are highlighted with the root sum square (RSS) of the eight major tidal constituents improving by
∼ 1.4 cm for the entire global ocean with the major improvement in RSS (∼ 2.2 cm) occurring in the coastal
region. Concerning the other global ocean tidal models, EOT20 shows an improvement of ∼ 0.2 cm in RSS compared to the closest model
(FES2014) in the global ocean. Variance reduction analysis was conducted comparing the results of EOT20 with FES2014 and EOT11a using the Jason-2,
Jason-3 and SARAL satellite altimetry missions. From this analysis, EOT20 showed a variance reduction for all three satellite altimetry missions
with the biggest improvement in variance occurring in the coastal region. These significant improvements, particularly in the coastal region,
provide encouragement for the use of the EOT20 model as a tidal correction for satellite altimetry in sea-level research. All ocean and load tide
data from the model can be freely accessed at https://doi.org/10.17882/79489 (Hart-Davis et al., 2021). The tide gauges from the TICON dataset used in the validation of the tide model, are available at https://doi.org/10.1594/PANGAEA.896587 (Piccioni et al., 2018a).
The influence of vegetation water dynamics on the ASCAT backscatter-incidence angle relationship in the Amazon

Published: August 2021

Abstract. Microwave observations are sensitive to plant water content and could therefore provide essential information on biomass and plant water status in ecological and agricultural applications. The combined data record of the C-band scatterometers on ERS 1/2, the Metop series and the planned Metop Second Generation satellites will span over 40 years, which would provide a long-term perspective on the role of vegetation in the climate system. Recent research has indicated that the unique viewing geometry of ASCAT could be exploited to observe vegetation water dynamics. The incidence angle dependence of backscatter can be described with a second order polynomial, the slope and curvature of which are related to vegetation. In a study limited to grasslands, seasonal cycles, spatial patterns and interannual variability in the slope and curvature were found to vary among grassland types and were attributed to differences in moisture availability, growing season length and phenological changes. To exploit ASCAT slope and curvature for global vegetation monitoring, their dynamics over a wider range of vegetation types needs to be quantified and explained in terms of vegetation water dynamics. Here, we compare ASCAT data with meteorological data and GRACE Equivalent Water Thickness (EWT) to explain the dynamics of ASCAT backscatter, slope and curvature in terms of moisture availability and demand. We consider differences in the seasonal cycle, diurnal differences, and the response to the 2010 and 2015 droughts across ecoregions in the Amazon basin and surroundings. Results show that spatial and temporal patterns in backscatter reflect moisture availability indicated by GRACE EWT. Slope and curvature dynamics vary considerably among the ecoregions. The evergreen forests, often used as a calibration target, exhibit very stable behaviour even under drought conditions. The limited seasonal variation follows changes in the radiation cycle, and may indicate phenological changes such as litterfall. In contrast, the diversity of land cover types within the Cerrado region results in considerable heterogeneity in terms of the seasonal cycle and the influence of drought on both slope and curvature. Seasonal flooding in forest and savanna areas also produced a distinctive signature in terms of the backscatter as a function of incidence angle. This improved understanding of the incidence angle behaviour of backscatter increases our ability to interpret and make optimal use of the ASCAT data record and VOD products for vegetation monitoring.
Daily soil temperature modeling improved by integrating observed snow cover and estimated soil moisture in the USA Great Plains

Published: August 2021

Abstract. Soil temperature (Ts) plays a critical role in land–surface hydrological processes and agricultural ecosystems. However, soil temperature data are limited in both temporal and spatial scales due to the configuration of early weather station networks in the USA Great Plains. Here, we examined an empirical model (EM02) for predicting daily soil temperature (Ts) at the 10 cm depth across Nebraska, Kansas, Oklahoma, and parts of Texas that comprise the USA winter wheat belt. An improved empirical model (iEM02) was developed and calibrated using available historical climate data prior to 2015 from 87 weather stations. The calibrated models were then evaluated independently, using the latest 5-year observations from 2015 to 2019. Our results suggested that the iEM02 had, on average, an improved root mean square error (RMSE) of 0.6 ∘C for 87 stations when compared to the original EM02 model. Specifically, after incorporating the changes in soil moisture and daily snow depth, the improved model was 50 % more accurate, as demonstrated by the decrease in RMSE. We conclude that, in the USA Great Plains, the iEM02 model can better estimate soil temperature at the surface soil layer where most hydrological and biological processes occur. Both seasonal and spatial improvements made in the improved model suggest that it can provide a daily soil temperature modeling tool that overcomes the deficiencies of soil temperature data used in assessments of climatic changes, hydrological modeling, and winter wheat production in the USA Great Plains.

Published: August 2021

Abstract. We present a tribute to Georg Friedrich Karl Hartung (1821–1891), a less-known non-academic German geologist, on his 200th anniversary. Influenced by eminent 19th century scientific personalities such as Oswald Heer, Charles Lyell, and Alexander von Humboldt, he performed pioneer geological observations and sampling in the Azores, Madeira, and Canaries volcanic archipelagos. Later in his life he travelled to the USA and explored the Scandinavian countries. His scientific endeavours were published in several books and papers, many of them co-authored by academic German geologists and palaeontologists. His works on the macaronesian islands are deemed as classics, many enriched by his own detailed geological illustrations.
EVACUATION ROUTING ASSESSMENT DURING EARTHQUAKE OCCURRENCE IN BUTUAN CITY USING GIS TECHNIQUES
Authors: Cauba Jr. A. G. , Ignacio S. N.
Published: August 2021

Abstract. Butuan City lies along and is being transected by the Philippine Fault: Surigao Segment. As earthquakes occur more recently, the city is more vulnerable to earthquake hazards, especially soil liquefaction. With the city proper situated mostly on areas susceptible to soil liquefaction and with no constructive evacuation plan against this kind of hazard, it puts the city at risk. This problem highlights the importance of vulnerability assessment for the identification of the road networks that would be most optimal to use in occurrence of an earthquake and an earthquake induced liquefaction. With seven parameters to consider for the assessment, it would be easier to assess by using the pairwise comparison technique of the Analytical Hierarchy Process (AHP) and Geographic Information System (GIS). The analysis was performed by using AHP to assign weights to the parameters and using these weights to classify the road networks into vulnerability classes. The result of the analysis yielded to 34.87% of the road networks with low vulnerability, 65.09% has medium vulnerability and 0.03% are considered to be highly vulnerable. Majority of the road networks especially in the city proper exhibit medium vulnerability in terms of earthquake occurrences. With unavoidable chances that this kind of disaster would happen, these results would benefit the decision makers involved in disaster risk reduction.
Efficient transient testing procedure using a novel experience replay particle swarm optimizer for THD-based robust design and optimization of self-X sensory electronics in industry 4.0
Authors: Zaman Qummar , Alraho Senan , König Andreas
Published: August 2021

Abstract. This paper aims to improve the traditional calibration method for reconfigurable self-X (self-calibration, self-healing, self-optimize, etc.) sensor interface readout circuit for industry 4.0. A cost-effective test stimulus is applied to the device under test, and the transient response of the system is analyzed to correlate the circuit's characteristics parameters. Due to complexity in the search and objective space of the smart sensory electronics, a novel experience replay particle swarm optimization (ERPSO) algorithm is being proposed and proved a better-searching capability than some currently well-known PSO algorithms. The newly proposed ERPSO expanded the selection producer of the classical PSO by introducing an experience replay buffer (ERB) intending to reduce the probability of trapping into the local minima. The ERB reflects the archive of previously visited global best particles, while its selection is based upon an adaptive epsilon greedy method in the velocity updating model. The performance of the proposed ERPSO algorithm is verified by using eight different popular benchmarking functions. Furthermore, an extrinsic evaluation of the ERPSO algorithm is also examined on a reconfigurable wide swing indirect current-feedback instrumentation amplifier (CFIA). For the later test, we proposed an efficient optimization procedure by using total harmonic distortion analyses of CFIA output to reduce the total number of measurements and save considerable optimization time and cost. The proposed optimization methodology is roughly 3 times faster than the classical optimization process. The circuit is implemented by using Cadence design tools and CMOS 0.35 µm technology from Austria Microsystems (AMS). The efficiency and robustness are the key features of the proposed methodology toward implementing reliable sensory electronic systems for industry 4.0 applications.
Virtual decoupling to break the simplification versus resolution trade-off in nuclear magnetic resonance of complex metabolic mixtures
Authors: Charlier Cyril , Cox Neil , Prud'homme Sophie Martine , Geffard Alain , Nuzillard Jean-Marc , Luy Burkhard , Lippens Guy
Published: August 2021

Abstract. The heteronuclear single quantum correlation (HSQC) experiment developed by Bodenhausen and Ruben (1980) in the early days of modern nuclear magnetic resonance (NMR) is without a doubt one of the most widely used experiments, with applications in almost every aspect of NMR including metabolomics. Acquiring this experiment, however, always implies a trade-off: simplification versus resolution. Here, we present a method that artificially lifts this barrier and demonstrate its application towards metabolite identification in a complex mixture. Based on the measurement of clean in-phase and clean anti-phase (CLIP/CLAP) HSQC spectra (Enthart et al., 2008), we construct a virtually decoupled HSQC (vd-HSQC) spectrum that maintains the highest possible resolution in the proton dimension. Combining this vd-HSQC spectrum with a J-resolved spectrum (Pell and
Keeler, 2007) provides useful information for the one-dimensional proton
spectrum assignment and for the identification of metabolites in Dreissena polymorpha (Prud'homme
et al., 2020).
Extreme wind shear events in US offshore wind energy areas and the role of induced stratification
Authors: Debnath Mithu , Doubrawa Paula , Optis Mike , Hawbecker Patrick , Bodini Nicola
Published: August 2021

Abstract. As the offshore wind industry emerges on the US East Coast, a comprehensive understanding of the wind resource – particularly extreme events – is vital to the industry's success. Such understanding has been hindered by a lack of publicly available wind profile observations in offshore wind energy areas. However, the New York State Energy Research and Development Authority recently funded the deployment of two floating lidars within two current lease areas off the coast of New Jersey. These floating lidars provide publicly available wind speed data from 20 to 200 m height with a 20 m vertical resolution. In this study, we leverage a year of these lidar data to quantify and characterize the frequent occurrence of high-wind-shear and low-level-jet events, both of which will have a considerable impact on turbine operation. In designing a detection algorithm for these events, we find that the typical, non-dimensional power-law-based wind shear exponent is insufficient to identify many of these extreme, high-wind-speed events. Rather, we find that the simple vertical gradient of wind speed better captures the events. Based on this detection method, we find that almost 100 independent events occur throughout the year with mean wind speed at 100 m height and wind speed gradient of 16 m s−1 and 0.05 s−1, respectively. The events have strong seasonal variability, with the highest number of events in summer and the lowest in winter. A detailed analysis reveals that these events are enabled by an induced stable stratification when warmer air from the south flows over the colder mid-Atlantic waters, leading to a positive air–sea temperature difference.

STUDENTS’ INFORMAL INFERENCE ABOUT THE BINOMIAL DISTRIBUTION OF “BUNNY HOPS”: A DIALOGIC PERSPECTIVE
Authors: KAZAK SIBEL , FUJITA TARO , WEGERIF RUPERT
Published: August 2021

The study explores the development of 11-year-old students’ informal inference about random bunny hops through student talk and use of computer simulation tools. Our aim in this paper is to draw on dialogic theory to explain how students make shifts in perspective, from intuition-based reasoning to more powerful, formal ways of using probabilistic ideas. Findings from the study suggest that dialogic talk facilitated students’ reasoning as it was supported by the use of simulation tools available in the software. It appears that the interaction of using simulation tools, talk between students, and teacher prompts helps students develop their understanding of probabilistic ideas in the context of making inferences about the distribution of random bunny hops.

Using autoethnography to create narratives to understand musical taste and the experience of collaborative music performance
Authors: Brown Judith Elizabeth
Published: August 2021

For the past decades, insightful memoirs have been published by collaborative pianists,

providing an insider’s perspective on the art of piano accompaniment. This paper draws

on my doctoral thesis that used an autoethnographic narrative to explore the

experiences of collaborative music performance from the perspective of a piano

accompanist. The narrative incorporated creative writing elements such as direct

speech and descriptive scene setting to recreate the experience of collaborative music

performance, allowing the reader to gain some insight into its creative process, and thus

understand elements of musical taste and how this impacts on the experience of

collaborative music performance. The paper argues that this methodology provides an

appropriate way to examine such subjective experiences and that the use of

autoethnographic narrative, incorporating creative writing techniques, can be a useful

addition to music research methodologies, particularly in the field of music

performance research.

historical information about a particular time and place that can prove interesting

for readers. Author and ceramicist Edward de Waal used this approach to create his

award-winning family memoir The Hare With Amber Eyes. This paper uses a

personal case study to illustrate how an object biography of pieces of Herend –

world-famous Hungarian porcelain – can be used in creating a memoir that

describes aspects of my family history. Under normal circumstances, I would not

have chosen to keep these pieces after my parents’ death, as the objects are not to

my taste, that is, not aesthetically pleasing to me. Yet, they have great sentimental

value because they represent the story of important landmarks in my families’

history, including how my paternal grandparents met, and my own pilgrimage to

Hungary.
A Greek culinary odyssey to New Zealand, the furthest shore
Authors: Pittaway Gail
Published: August 2021

New Zealand is perhaps the furthest shore that the influence of Greek cuisine has

reached, after receiving Greek immigrants in their largest numbers as part of the

general diaspora of Greeks before and after the Second World War. Strong connections

were formed between New Zealand and Greece, perhaps none more so than during the

Battle of Crete in 1941, where ‘kiwi’ soldiers fought to defend Greeks. The majority of

Greek immigrants to New Zealand settled in Wellington, the capital and then the most

cosmopolitan of the small nation’s cities, where a major form of employment was in

the food and hospitality industry. This paper reflects on the culinary impact of these

immigrants on New Zealand after the war, and identifies some of the stories they tell of

migration, work and identity though the food they ate at home.

Endoscopic surgery, which was first introduced in the late 1980s, has rapidly become widespread. However, despite its popularity, the occurrence of intraoperative organ damage has not necessarily decreased. To avoid intraoperative bile duct injury in laparoscopic cholecystectomy, which is one of the most popular procedures in endoscopic surgery, we are developing a laparoscopic surgical system that uses Artificial Intelligence (AI) to identify four anatomical landmarks (cystic duct of the gallbladder, common bile duct, lower surface of hepatic S4, and Rouviere’s sulcus, related to “Calot’s triangle") in real time during surgery. The development process consists of 5 steps: 1) identification of anatomical landmarks, 2) collection and creation of teaching data, 3) annotation and deep learning, 4) validation of development model, and 5) actual clinical performance evaluation. At present, anatomical landmarks can be identified with high accuracy in an actual clinical performance test in laparoscopic cholecystectomy, whereas issues for practical clinical use, such as a need to recognize the scene of surgical steps and surgical difficulties related to inflammation of the gallbladder, have also been clarified. The development of an AI-navigation system for endoscopic surgery, which could identify anatomical landmarks in real time during surgery, could be expected to support surgeons' decisions, reduce surgical complications, and contribute to improving the quality of surgical treatments.

Introduction: Robotic systems provide a platform for surgeons to expand their capabilities, allowing them to perform complex procedures safely and efficiently. Within the field of benign gynecology, this has become an increasingly popular option since receiving Food and Drug Administration (FDA) approval in 2005. However, the appropriate indications for robotic versus laparoscopic surgery continue to be debated. Materials and Methods: Literature was reviewed to provide a comprehensive, evidence-based evaluation of the advantages and pitfalls of robotic surgery, the applications of robotic surgery for benign gynecologic procedures in comparison to conventional laparoscopy, and the role of robotic surgery as an educational tool. Results: Robotic surgery has favorable outcomes for surgeons in the areas of ergonomics, dexterity, and fatigue. Cost comparisons are widely varied and elaborate. Most patient outcomes are comparable between robotic and laparoscopic hysterectomies and endometriosis resections. In patients with a body mass index >30mg/m2 and uteri >750mg, hysterectomy outcomes are improved when surgery is done robotically. The use of the robotic system may be beneficial for patients undergoing myomectomy. Robotic surgery confers advantages for trainees and novice surgeons. There is no consensus on a standardized curriculum for robotic training or credentialing process for experienced surgeons. Conclusion: Robotic surgery has distinct features that make it a valuable tool for gynecologic surgeons. There are no clear indications regarding when a robotic route should be chosen but could be considered when above average complexity is anticipated and when training new surgeons.

Introduction: Prior publications have demonstrated chemical and physical alteration of hernia mesh analyzed after explantation from the body. The specific alteration documented is oxidative degradation of polypropylene mesh fibers. An animal study recently published has demonstrated that adipose tissue attachment is present instead of reparative fibrous tissue infiltration in an average of 10.9–18.9% of the intramesh healing for a variety of clinically used knitted polypropylene mesh products; 8.0% for knitted polyester meshes. This study also found that in comparison to the knitted mesh products, non-woven polypropylene mesh reduced adipose tissue attachment to 1% or less, which was a statistically significant difference. Materials and Methods: Samples of explanted polypropylene mesh from eight patients were analyzed for the presence of adipose tissue attachment, reparative fibrous tissue infiltration, and oxidative changes. Greater adipose tissue attachment areas were compared with areas of greater reparative fibrous tissue infiltration for evidence of oxidative changes in the mesh to determine if the areas of higher adipose tissue attachment correlated with an increase in oxidative changes. Results: Intra mesh healing of clinically explanted knitted meshes demonstrated adipose tissue content from 0.0% to 49.1% per analyzed segment. The oxidation index, a measure of the degree of oxidative degradation in that portion of the mesh, was higher in seven of the eight areas of greater adipose tissue attachment than areas of greater reparative fibrous tissue infiltration. Conclusion: Adipose tissue attachment does occur in knitted and woven polypropylene hernia meshes. The presence of adipose tissue may contribute to an increase in oxidative changes in knitted polypropylene hernia mesh fibers.

Debridement is a standard part of wound care that is used on both acute and chronic wounds. Current methods of wound debridement include: autolytic based on the natural immune response, surgical, enzymatic based on application of exogenous proteases, mechanical using water jets and ultrasound, and biological using live organisms such as maggots. The choice of individual methods involves a trade-off between speed of treatment, selectivity, and pain. Irreversible electroporation via the application of pulsed electric fields has been used as a novel approach for deep tissue ablation, sometimes in conjunction with chemotherapy, as in the case of tumors, and also in cases where high precision is needed in otherwise very fragile tissues, such as for treating diabetic neuropathy and in epicardial atrial ablation. This method could be readily extended to wound care as it is both rapid and relatively painless, and it is also effective at decreasing bacterial load and clearing biofilms. Furthermore, the process primarily targets cells leaving the extracellular matrix relatively intact, thus providing a suitable natural scaffold for host cellular invasion and regrowth. A unique aspect of the use of pulsed electric fields is that around the region where ablation is perfomed, electric fields of lower energy are dissipated into the healthy tissue. There is a range of electric fields that are known to stimulate cellular functions, in particular migration and proliferation, and that may contribute to the healing process after electroporation. While irreversible electroporation is a potentially useful alternative to other debridement methods, future clinical application awaits technological advances in electrode design that will enable precise delivery of the therapy in wounds of various sizes and depths.
