Published: July 2022

Improved understanding of the factors that limit crop yields in farmers’ fields will play an important role in increasing regional food production while minimizing environmental impacts. However, causes of spatial variability in crop yields are poorly known in many regions because of limited data availability and analysis methods. In this study, we assessed sources of between‐field wheat (Triticum aestivum L.) yield variability for two growing seasons in the Yaqui Valley, Mexico. Field surveys conducted in 2001 and 2003 provided data on management practices for 68 and 80 wheat fields throughout the Valley, respectively, while yields on these fields were estimated using concurrent Landsat satellite imagery. Management–yield relationships were analyzed with t tests, linear regression, and regression trees, all of which revealed significant but year‐dependent impacts of management on yields. In 2001, an unusually cool year that favored high yields, N fertilizer was the most important source of between‐field variability. In 2003, a warmer year with reduced irrigation water allocations, the timing of the first postplanting irrigation was found to be the most important control. Management explained at least 50% of spatial yield variability in both years. Regression tree models, which were able to capture important nonlinearities and interactions, were more appropriate for analyzing yield controls than traditional linear models. The results of this study indicate that adjustments in management can significantly improve wheat production in the Yaqui Valley but that the relevant controls change from year to year.

Core Ideas

The experimental design was inappropriate in relation to the objectives. Eleven factors were confounded.

Contrasting previous crops, methods of N application and N sources were assumed to be equivalent.

Results of two‐way ANOVAs were not reported to support models and mean comparisons.

Interpretation should consider non‐responsive trials and confounding factors.

Incomplete statistical and economic analyses led to higher economic N rate.

Published: July 2022

Objetivo: analisar o efeito da eletroestimulação percutânea associada à prática de exercício físico sobre a gordura localizada em região abdominal de mulheres jovens. Método: Foi realizado um estudo clínico prospectivo, randomizado e simples-cego, do qual participaram 40 voluntárias, com idades entre 18 e 38 anos, que apresentaram razão cintura/estatura (RCEst) entre 0,44 e 0,80. Asparticipantes foram submetidas à avaliação de composição corporal por bioimpedância e perimetria, e responderam a um questionáriode estilo de vida. Divididas em grupo controle (atividade física) e grupo experimental (eletrolipólise associada à atividade física), elas realizaram 10 sessões com tempo de 50 minutos para cada modalidade. Os dados foram analisados com estatística descritiva e análise de variância a dois fatores para medidas repetidas. O nível de significância α estabelecido foi de 5% (α< 0,05).Resultados: No questionário, os dois grupos foram classificados como possuindo estilo de vida muito bom. A comparação dos resultados das medidas corporais avaliadas após a intervenção revelou redução significante no perímetro da cintura em ambos os grupos e no perímetro abdominal apenas no grupo experimental. Houve redução do percentual de massa gorda apenas no grupocontrole. Conclusão: A eletrolipólise aplicada de forma percutânea, associada ao exercício físico, foi suficiente para proporcionar alterações significantes na perimetria da região da cintura. Apesar disto, não foi observada redução significante de peso ou massagorda decorrente da aplicação da eletrolipólise.

Published: July 2022

The calcium silicate hydrate (CSH) was synthesized from the solid waste residue (SWR) of the Alum Factory, and was used for phosphate abatement from an aqueous solution. Fixed-bed column adsorption experiments were conducted at different flow rates (5, 7.5, and 10 mL/min) and bed depths (6, 9, and 12 cm) at an initial pH and phosphate concentrations of 5 and 5.5 mg/L, respectively. The breakthrough curve analysis was developed and tabulated for the effects of the flow rate and bed depth. Fixed-bed adsorption models, namely the Thomas model, the Yoon–Nelson model, and Bed Depth Service Time (BDST) model were fitted to the experimental data. The R2 values observed for the Thomas model and the Yoon–Nelson model were 0.96 and 0.98, respectively, at the flow rate of 7.5 mL/min and bed depth of 9 cm with the breakthrough adsorption capacity of 5.67 mg/g. The synthesized CSH was also tested for its phosphate removal efficiency using local wastewater treatment plant effluent. About 1,658 mL of real wastewater was treated for 249 min before the standard threshold limit (1 mg/L) was reached. This study prevails that the synthesized CSH could be applied to remove phosphate from real wastewater under a continuous flow adsorption system.

Published: July 2022

O presente artigo versa sobre a trajetória de formação e implementação da política de assistência social no Brasil, desde a sua instituição no Sistema de Seguridade Social, pela Constituição Federal de 1988, até a aprovação da lei do SUAS em 2011. Nosso objetivo é apresentar uma discussão sobre a política a partir da perspectiva do neoinstitucionalismo na análise de políticas públicas. Buscamos relacionar também o emprego de arranjos institucionais e seus desdobramentos na efetivação dos objetivos propostos pelos formuladores da política. Para tanto, empregamos a metodologia de análise qualitativa com uso das técnicas de pesquisa bibliográfica e consulta documental. Os resultados mostram que a influência das instituições e dos atores na formação e implementação resultaram numa política pública sustentada por um sistema teoricamente bem elaborado, com princípios e diretrizes centrados na perspectiva do direito e da equidade social. Porém os mecanismos que propiciam a sua operacionalização rebatem nas concepções políticas e econômicas, desfavoráveis ao alcance dos objetivos da política.
The Subthalamic Nucleus: A Hub for Sensory Control via Short Three-
Lateral Loop Connections with the Brainstem?

Published: July 2022

The subthalamic nucleus (STN) is classically subdivided into sensori-motor, associative and limbic regions, which is consistent with the involvement of this structure in not only motor control, but also in cognitive and emotional tasks. However, the function of the sensory inputs to the STN’s sensori-motor territory is comparatively less well explored, although sensory responses have been reported in this structure. There is still a paucity of information regarding the characteristics of that subdivision and its potential functional role in the basal ganglia processing and more widely in associated networks. In this perspective paper, we summarize the type of sensory stimuli that have been reported to activate the STN, and describe the complex sensory properties of the STN and its anatomical link to a sensory network involving the brainstem, characterized in our recent work. Analyzing the sensory input to the STN led us to suggest the existence of previously unreported three-lateral subcortical loops between the basal ganglia and the brainstem which do not involve the cortex. Anatomically, these loops closely link the STN, the substantia nigra pars reticulata and various structures from the brainstem such as the superior colliculus and the parabrachial nucleus. We also discuss the potential role of the STN in the control of sensory activity in the brainstem and its possible contribution to favoring sensory habituation or sensitization over brainstem structures to optimize the best selection of action at a given time.

Published: July 2022

Ketiadaan modal keuangan dan hilangnya pendapatan pekebun setelah di masa tanaman belum menghasilkan menjadi alasan utama penyebab tertundanya kegiatan peremajaan di perkebunan sawit rakyat. Kelompok Tani swadaya Sido Makmur yang berlokasi di Riau telah meremajakan kebun seluas 20 hektar dengan sistem tumbang serempak/total disertai dengan sistem tumpang sari tanaman sayuran. Meski sistem ini membutuhkan biaya yang cukup tinggi, ternyata berhasil diterapkan oleh Kelompok tani ini. Penelitian ini dilakukan untuk 1) mengetahui alasan pekebun memilih melakukan peremajaan dengan sistem tumpang sari, 2) mengetahui manfaat finansial dari penerapan tumpang sari, dan 3) mengetahui dampak sistem tumpang sari terhadap status kesuburan tanah dan pertumbuhan tanaman kelapa sawit pada masa tanaman belum menghasilkan. Penelitian ini dilakukan di Desa Kumain, Kecamatan Rokan Hulu pada Oktober 2019. Analisis data dilakukan menggunakan usahatani tanaman sela dan analisis dampak budidaya tanaman sela terhadap kesuburan tanah di areal tanaman kelapa sawit TBM 1. Pengumpulan data dilakukan dengan cara wawancara mendalam (indepth interview) melibatkan 5 orang anggota kelompok tani. Data yang dikumpulkan meliputi praktik pola tanam dalam setahun, biaya input produksi, harga jual, hasil produksi, dan pendapatan. Selain itu juga dilakukan pengambilan sampel tanah pada 5 titik pengamatan ditiap kebun. Hasil penelitian menunjukkan bahwa sistem tumpang sari tanaman sela pada kebun kelapa sawit rakyat di Tandun, Rokan Hulu, Riau secara ekonomi layak diusahakan. Hal ini dapat dinilai dari besaran nilai RCR yang lebih dari satu pada seluruh jenis tanaman sela yang diusahakan. Hal ini juga menjelaskan bahwa usahatani tumpang sari tanaman sela berupa tanaman holtikultura dapat menjadi alternatif pendapatan semasa tanaman kelapa sawit tanaman belum menghasilkan. Lebih lanjut, hasil analisis kadar hara tanah dan pertumbuhan vegetatif tanaman antara plot kontrol dan plot tumpang sari memiliki nilai yang cukup serupa. Sehingga dapat dikatakan sistem tumpang sari ini direkomendasikan karena tidak memberikan efek buruk terhadap pertumbuhan tanaman dan kesuburan tanah.

Feasibility of Virtual Reality Exercises at Home for Post–COVID-19 Condition: Cohort Study
Authors: Groenveld Tjitske , Achttien Retze , Smits Merlijn , de Vries Marjan , van Heerde Ron , Staal Bart , van Goor Harry ,   COVID Rehab Group
Published: July 2022

Background

Between 30% to 76% of COVID-19 patients have persistent physical and mental symptoms, sometimes up to 9 months after acute COVID-19. Current rehabilitation is mostly focused on the physical symptoms, whereas experts have agreed on the need for a biopsychosocial approach. A novel approach such as virtual reality (VR) rehabilitation at home might benefit patients and therapists, especially considering the expected rush of patients with post–COVID-19 condition needing rehabilitation.

Objective

The aim of this study was to investigate the feasibility of self-administered VR exercises at home for post–COVID-19 condition.

Methods

This was a single-arm feasibility study in an outpatient care setting. Patients who needed physiotherapy because of post–COVID-19 condition were included as determined by the treating physiotherapist. Participants performed VR physical exercises at home for a period of 6 weeks and were allowed to perform VR mental exercise through applications available on the VR platform to reduce stress and anxiety and promote cognitive functioning. The main outcomes were related to feasibility (ie, duration and frequency of VR use), safety (ie, adverse events), patient satisfaction, and reasons to withdraw. Physical performance, daily activities, cognitive functioning, anxiety and depression, and the quality of life were measured before and after.

Results

In total, 48 patients were included; 1 (2%) patient did not start VR, and 7 (15%) patients withdrew, mostly due to dizziness. Almost 70% (33/47) of participants reported experiencing any adverse event during VR exercising. However, only 25% (9/36) recalled these events at the end of the intervention period. The majority (27/36, 75%) of the patients described VR as having a positive influence on their recovery, and the global satisfaction score was 67%. The average VR use was 30 minutes per session, 3-4 times a week for 3-6 weeks. The overall use of VR applications was almost equally distributed over the 3 sets of VR exercises (physical, relaxing, and cognitive). However, the use frequency of physical exercises seemed to decrease over time, whereas the use of cognitive and relaxation exercises remained stable. Physical performance and quality of life outcomes were significantly improved after 6 weeks.

Conclusions

VR physical exercises at home is feasible and safe with good acceptance in a significant percentage of patient with post–COVID-19 condition.

Published: July 2022

This study explored the relationships between green brand uniqueness, green brand credibility, green brand innovativeness, green brand love, and green customer citizenship behavior in Taiwan's restaurant context. We conducted a survey of 406 customers of the restaurant Wang Steak. Our
results indicate that green brand uniqueness, green brand credibility, and green brand innovativeness all had positive relationships with green brand love. Green brand love was also positively related to green customer citizenship behavior. Our findings provide insight into the relationships
between perceived brand uniqueness, brand credibility, brand innovativeness, and brand love with customers' citizenship behaviors in the green restaurant context. Restaurant managers should promote the unique attributes of green activities, fulfill their green promises to customers, and develop
brand innovativeness related to green issues, thereby strengthening customers' green brand love and green citizenship behavior.
CLIMATE CHANGE AND COVID-19 IN THE KRUGER TO CANYONS BIOSPHERE REGION, SOUTH AFRICA AND AMAZONAS, BRAZIL
Authors: Dos Santos Monika
Published: July 2022

Climate change is predicted to exert further stress on already exploited ecologies and healthcare systems, added to this, the coronavirus SARS-CoV-2 (Covid-19) has signified a stimulus to revolutionize existing models of sustainable development in broad, and sustainable supply chains in the healthcare sector in particular. The Kruger to Canyons Biosphere Region in South Africa and the  Amazonas state in Brazil serve as geographic case studies for this paper. The impact of economic globalization, natural catastrophes such as droughts, economic and geopolitical stresses, deforestation, economic and healthcare access inequalities in these two biomes converge with issues of climate change, and undercut coping mechanisms that are customarily used to oversee extreme events such as pandemics. The Covid-19 pandemic has deepened many of the economic and social difficulties which South Africa and Brazil are already facing. In comparison to Brazil, South Africa’s overall response to the pandemic can be regarded as a standout. By borrowing from best practices from prior public health responses to heath emergencies in South Africa, such as the tuberculosis and the HIV/AIDS crisis, South Africa has demonstrated its comparatively successful means of dealing with Covid-19.
NEOEXTRACTIVISMO EN LA REPÚBLICA DEMOCRÁTICA DEL CONGO Y ANGOLA. ENTRE LA GLOBALIZACIÓN NEOLIBERAL, LAS TENDENCIAS REGIONALES Y PARTICULARIDADES LOCALES
Authors: Williams David Mouzo
Published: July 2022

El presente artículo pretende una aproximación a la formación de enclaves extractivos en la República Democrática del Congo, haciendo un estudio comparativo con la República de Angola, en pos de dar cuenta de las tendencias regionales que les hacen similares, y las particularidades locales que singularizan sus respectivas inserciones neoliberales. La hipótesis de este trabajo, tomando los aportes de autores como James Ferguson (2007), es que se ha venido instalando un paradigma desde 1980 en adelante en gran parte del continente africano, que aquí denominamos como “neoextractivismo”, incorporando el modelo de Maristella Svampa (2019), que lo pensaba para América Latina. Mientras que Ferguson concentra su análisis del neoliberalismo en África en Angola, donde observa la instalación de una producción petrolífera cualitativa y espacialmente separada del resto de la sociedad, y Svampa lo hace en relación con las concesiones que tanto gobiernos nacional-populares como neoliberales de la región latinoamericana han hecho a las compañías extractivas, aquí se propone un matiz adicional. El caso congolés da cuenta de la imposición de una brecha que separa las ganancias de la explotación respecto al Estado y su población, como en el caso angoleño, pero con una serie de particularidades históricas que ha combinado el accionar de milicias, rutas ilegales, liberalización neoliberal e inserción de los capitales extranjeros. Este sincretismo ha privado de las ganancias de los minerales estratégicos a los trabajadores locales que los explotan y del gobierno en cuyo territorio se encuentran subterráneamente. Ambos casos formarían parte de una más amplia reorganización capitalista que ha venido operando en el continente africano desde 1970 en adelante, y que necesariamente requiere de un estudio comparativo, tomando aportes de los análisis de la región latinoamericana, en tanto parte del Sur global.

Published: July 2022

A 77-year-old woman underwent mitral valve replacement and tricuspid
annuloplasty for severe mitral stenosis and tricuspid regurgitation with
pulmonary hypertension. Two months later, the patient was readmitted
because of marked edema. A new harsh pansystolic murmur was auscultated,
and echocardiography revealed a jet from the left ventricle to the right
atrium but no perivalvular leakage was detected at the mitral valve
position. At operation, an 6mm defect adjacent to the tricuspid annulus
in the interatrial septum and detachment of the anterior edge of the
tricuspid ring were detected. The defect was closed using a pericardial
patch. An inadequate stitch at the anteroseptal commissure in the
previous operation led to left ventricular-right atrial communication.

Foot and mouth disease (FMD) is a highly contagious disease affecting
cloven-hoofed animals which has been well documented as one of the major
animal diseases that causing serious economic loss of livestock sectors.
The disease is endemic in many countries, particularly in Asia and
Africa. Indonesia has declared disease-free country since 1986 and the
World Organization of Animal Health (WOAH/OIE) has recognised Indonesia
as FMD-free country without vaccination in 1990. However, FMD virus was
detected from a number of disease outbreaks in cattle and goat in
Indonesia in May 2022. This study report for the first time the
detection and identification of serotype O/ME-SA/Ind-2001 lineage in
Indonesia. Although the Indonesian serotype O/ME-SA/Ind-2001 viruses
appeared belonging to the Ind-2001e sublineage, they formed a unique
cluster with 95.3% average nucleotide sequence similarity to Ind-2001e
viruses from other Asia countries. The source of virus incursion into
Indonesia is still unresolved; however, illegal trade of live animals
from endemic areas in Southeast Asia is the suspected route which should
be further investigated.

matroid and fuzzy convergence structure. In this paper, notions of
L-topological neighborhood relation space, L-topological derived
neighborhood relation space and L-topological derived neighborhood space are
introduced. It is proved that all of these spaces are categorically
isomorphic to L-topological internal relation space and L-topological
neighborhood space. Also, notions of L-topological remotehood relation
space, L-topological derived remotehood relation space and L-topological

Inequalities on the (p,q)-mixed volume involving Lp centroid bodies and Lp intersection bodies
Authors: Hu Zejun , Li Hai
Published: July 2022

In this paper, applying for the Minkowski?s and H?lder?s integral
inequalities, we obtain four theorems about the (p, q)-mixed volume
involving the Lp centroid bodies and the Lp intersection bodies,
respectively. The former two theorems reveal the convexity of the
functionals related to the (p, q)-mixed volume, in terms of the dual
Blaschke addition introduced in [Journal of Geometric Analysis, 30 (2020)
3026-3034], and the latter two theorems expose the monotonicity of the other
functionals related to the (p, q)-mixed volume.

In this paper we present the curvature tensors of Kenmotsu manifold
satisfying the conditions W1(X,Y)? W0 = 0, W1(X,Y)? W1 = 0, W1(X,Y)? W2 =
0, W1(X,Y)? W3 = 0, W1(X,Y-)? W4 = 0 and W1(X,Y)? W*1 = 0. According to
these cases, Kenmotsu manifolds have been characterized. We consider that
some interesting results on a Kenmotsu metric manifold are obtained.
Uniqueness for stochastic scalar conservation laws on Riemannian manifolds revisited
Authors: Konatar Nikola
Published: July 2022

We revise a uniqueness question for the scalar conservation law with
stochastic forcing du + divgf(x,u)dt = ?(x,u)dWt, x ? M, t ? 0 on a smooth
compact Riemannian manifold (M,g) whereWt is the Wiener process and x ?
f(x,?) is a vector field on M for each ? ? R. We introduce admissibility
conditions, derive the kinetic formulation and use it to prove uniqueness in
a more straight-forward way than in the existing literature.
Generalized symplectic Golden manifolds and Lie Groupoids
Authors: Şahin Fulya
Published: July 2022

By considering the notion of Golden manifold and natural symplectic form on a
generalized tangent bundle, we introduce generalized symplectic Golden
structures on manifolds and obtain integrability conditions in terms of
bivector fields, 2-forms, 1-forms and endomorphisms on manifolds and
investigate isotropic subbundles. We also find certain relations between the
integrability conditions of generalized symplectic Golden manifolds and Lie
Groupoids which are important in mechanics as configuration space.
Study of the correlation between the expression of nuclear factor kappa B and proliferation regulatory proteins and chronic superficial gastritis
Authors: Hu Hui , Ma Zhijian , Ren Shouzhong , Xie Yiqiang
Published: July 2022

Background/Aim. Cell proliferation and the regulation of protein expression play an important role in gastritis, but in chronic superficial gastritis (CSG), they are rarely reported. The aim of this study was to determine the relationship between the expression of nuclear factor kappa B (NF-?B) and regulatory proteins and the rat CSG. Methods. The CSG rat model was established artificially, by chemical agents and irregular diet. The expression of epidermal growth factor receptor (EGFR) and proliferating cell nuclear antigen (PCNA) in the gastric mucosa of CSG rats was measured by immunohistochemistry, while mRNA expression levels of NF-?B p65 were detected by in situ hybridization. Results. There was more obvious infiltration of inflammatory cells in the gastric mucosa of CSG rats than in that of control rats, and the inflammation score was significantly increased. The expression levels of PCNA, EGFR, and NF-?B p65 mRNA in the gastric mucosal cells of CSG model rats increased significantly. Correlation analysis showed that the inflammation score was positively correlated with the expression levels of NF-?B p65 mRNA and EGFR, while it presented no significant correlation with the expression level of PCNA. In addition, there was a significant positive correlation between NF-?B p65 mRNA and EGFR levels. Conclusion. High expression of NF-?B and EGFR plays an important role in the occurrence and progression of CSG, and it is significantly positively correlated with the degree of inflammation in the gastric mucosa. Therefore, changes in NF-?B and EGFR expression may be used as important indicators for the assessment of CSG; changes in their expression levels are helpful to assess the degree of gastric mucosal lesions and progression of CSG.

CEO Narcissism and Properties of Analysts’ Forecasts
Authors: Marquez-Illescas Gilberto , Zhou Linying
Published: July 2022

SYNOPSIS

Using a sample of S&P 500 companies, this study constructs a measure of CEO narcissism and examines whether and how it impacts the accuracy and dispersion of analysts’ forecasts. Empirical evidence suggests that firms with narcissistic CEOs have higher accuracy and lower dispersion of such forecasts. In investigating the mechanism through which CEO narcissism impacts these properties, we find that firms with narcissistic CEOs are more likely to issue management earnings guidance, albeit less accurate, which results in significant differences in accuracy and dispersion of analysts’ forecasts. This study concludes that through more management voluntary disclosure, CEO narcissism has a positive impact on the accuracy and a negative impact on the dispersion of financial analysts’ forecasts. Although several studies have explored the effect of CEO narcissism on corporate financial reporting, this is the first study to expand such inquiry into the sector of financial analysts.

Spraying treatment of fresh-cut apples as a sustainable alternative to dipping for browning inhibition: a preliminary lab-scale study
Authors: Faller Noreen , Venir Elena , Zatelli Daniele , Bianchi Flavia
Published: July 2022

Several fresh-cut apple snacks are available on the market, and their color is highly relevant for consumers. As apple slices brown very quickly after cutting, dipping them in an antioxidant solution for a few minutes is common to avoid this phenomenon. However, this procedure has some limitations. Using the same solution for several immersion cycles over several hours can lead to cross-contamination and microbial growth. In addition, osmotic exchange phenomena in the immersion tank lead to a reduction in the concentration of the active ingredients of the antioxidant solution over time, which requires continuous readjustment of the concentrations. These aspects, together with the large quantities of exhausted antioxidant solution to be disposed of, are limiting factors that drive the search for alternative and more sustainable methods than dipping. In this work, a comparison between a conventional dipping treatment of fresh-cut apples and spraying at increasing volume of antioxidant solution was performed. Color, considered as the quality reference parameter, was visually assessed (occurrance of dark spots) and CIE Lab colorimetric indices were measured over a five-day experimental period. Based on dark spots and the changes in brightness (Δ L*), hue angle (Δ h) and chroma (Δ C*), some of the spraying treatments applied were found to be comparable to dipping in controlling browning. For all treatments, high intra- and inter-batch variability and within slices of the same apple was observed concerning both instrumental data and dark spots development, indicating that further investigation is needed to validate this result and to apply this procedure at an industrial level.

Background: Whether continuous renal replacement therapy (CRRT) should be applied to critically ill patients with both acute kidney injury (AKI) and cancer remains controversial because of poor expected outcomes. The present study determined prognostic factors for all-cause in-hospital mortality in patients with AKI and cancer undergoing CRRT.Methods: We included 471 patients with AKI and cancer who underwent CRRT at the intensive care unit of a Korean tertiary hospital from 2013 to 2020, and classified them by malignancy type. The primary outcomes were 28-day all-cause mortality rate and prognostic factors for in-hospital mortality. The secondary outcome was renal replacement therapy (RRT) dependency at hospital discharge.Results: The 28-day mortality rates were 58.8% and 82% in the solid and hematologic malignancy groups, respectively. Body mass index (BMI), presence of oliguria, Sequential Organ Failure Assessment (SOFA) score, and albumin level were common predictors of 28-day mortality in the solid and hematologic malignancy groups. A high heart rate and the presence of severe acidosis were prognostic factors only in the solid malignancy group. Among the survivors, the proportion with RRT dependency was 25.0% and 33.3% in the solid and hematologic malignancy groups, respectively. Conclusion: The 28-day mortality rate of cancer patients with AKI undergoing CRRT was high in both the solid and hematologic malignancy groups. BMI, presence of oliguria, SOFA score, and albumin level were common predictors of 28-day mortality in the solid and hematologic malignancy groups, but a high heart rate and severe acidosis were prognostic factors only in the solid malignancy group.
Pemodernan Atap Rumah Tradisional Jawa sebagai Upaya Pelestarian Kearifan Lokal

Pelestarian kearifan lokal di bidang arsitektur diharapkan mampu memberi kontribusi dalam menjaga keberlangsungan keberagaman budaya nusantara. Rumah sebagai produk warisan arsitektur tradisional mempunyai banyak tantangan untuk mengikuti perkembangan zaman. Sebagai bagian dari bangunan rumah, atap mengambil peran yang sangat signifikan dalam menentukan langgam atau gaya bangunan. Kita dapat mengetahui asal/lokasi rumah tradisional di Indonesia dari bentuk atapnya. Bahkan di beberapa budaya di Indonesia, bentuk atap rumah bahkan mempunyai peran untuk menunjukkan status/tingkatan sosial penghuninya. Proses adaptasi dan modifikasi bentuk rumah tradisional diharapkan mampu menjaga kelestarian kearifan lokal. Salah satu studi kasus yang akan dipaparkan pada makalah ini yaitu rumah tinggal di perumahan Hyarta Residence, Yogyakarta. Metode penelitian yang dilakukan yaitu pendekatan analisis kualitatif dengan melakukan studi observasi lapangan dan studi literatur. Penelitian akan difokuskan pada bagian atap dengan aspek yang diteliti terdiri dari bentuk, fungsi dan material yang digunakan. Data-data hasil pengamatan dan kajian literatur kemudian diolah dan dibuat analisis deskriptif berupa penjelasan mengenai bentuk atap, fungsi dan bahan struktur rangka penutup atap dalam rangka menjaga kelestarian kearifan lokal. Dari hasil kajian yang dilakukan, diketahui bahwa upaya pelestarian kearifan lokal, khususnya bentuk atap rumah tradisional jawa, bisa dilakukan dengan penggunaan material bahan pengganti yang lebih modern selama tidak mengubah bentuk dan fungsi komponen bangunan.

Penelitian ini bertujuan untuk mengumpulkan informasi dan berbagi pengetahuan mengenai efektifitas penggunaan kembali material dalam suatu pembangunan. Beberapa isu yang melatarbelakanginya adalah perkembangan infrastruktur. Perkembangan infrastruktur di Indonesia adalah salah satu kegiatan yang ikut andil dalam kerusakan lingkungan. Kerusakan yang disebabkan bidang infrastruktur ini sejalan dengan bertambahnya populasi penduduk. Di mana semakin bertambahnya jumlah penduduk maka semakin besar pula tuntutan kebutuhan akan fasilitas-fasilitas yang menjadi wadah aktivitas manusia. Solusi yang dapat dilakukan adalah dengan menggunakan sistem pembangunan yang berkelanjutan atau sustainable construction. Peran dari material yang dapat mendukung pembangunan berkelanjutan adalah penggunaan kembali (re-use) material dalam proses pembangunan. Penelitian ini membahas penerapan konsep sustainable pada rumah tinggal dari segi penggunaan ulang material, serta membahas mengenai contoh penerapan alternatif material sustainable pada rumah tinggal. Metode penelitian yang digunakan adalah analisis deskriptif untuk pemenuhan poin-poin konsep 3R (Reduce, Reuse, dan Recycle). Dari konsep 3R, konsep reuse adalah konsep yang akan dibahas dan menjadi poin utama di penulisan paper ini. Reuse secara garis besar artinya adalah “Menggunakan Kembali”. Reuse dalam arsitektur berarti menggunakan kembali bahan bangunan yang masih bisa terpakai, contohnya botol-botol kaca bekas, sisa pecahan keramik, papan kayu yang kondisinya masih baik, bahkan seperti kaca mobil bekas dapat digunakan kembali ke dalam sebuah pembangunan. Hasil penelitian ini adalah berupa contoh penerapan alternatif material pada rumah tinggal yang memenuhi konsep sustainable dari segi material.
