Authors: BOZTEPE TAŞKIRAN Hatun
Published: April 2022

Kamusal halkla ilişkiler, merkezi ve yerel yönetim kurumları tarafından ortaya konan halkla ilişkiler strateji ve uygulamalarını kapsamaktadır. Kamu kurumları, kamu sermayesiyle kurulmakta ve kamusal hizmet sunumu yoluyla kamu yararının ortaya çıkmasını amaçlamaktadır. Kamu kurumlarının amaçlarına başarılı biçimde ulaşabilmesi ve kurumsal misyonlarını yerine getirebilmesi için halkla ilişkiler uygulamaları gereklilik taşımaktadır. Sürdürülebilirlik son yıllarda uluslararası kuruluşların, devlet yönetimlerinin, sivil toplum kuruluşlarının, özel sektör kuruluşlarının ve toplumun gündeminde yer edinmiş bir konudur. Aynı zamanda da kamusal halkla ilişkiler bağlamında yönetilmesi gereken bir konu olarak ilgi uyandırmaktadır. Özel sektör kuruluşlarının sorumluluk yaklaşımı bağlamında önem atfettiği sürdürülebilirlik, kamusal politika ve uygulamalarla ilişkili birtakım amaçlarla bağlantılı olması nedeniyle kamusal halkla ilişkiler çabaları açısından da önem taşımaktadır. Bu çalışmada temel bir kamu kurumu olan belediyeler tarafından gerçekleştirilen sürdürülebilirlik uygulamaları kamusal halkla ilişkiler bağlamında ele alınmıştır. Türkiye’deki 30 büyükşehir belediyesinin Birleşmiş Milletler Kalkınma Programı tarafından ortaya konan sürdürülebilirlik amaçlarına ulaşmaya yerel düzeyde katkı sunacak uygulamalar gerçekleştirip gerçekleştirmediklerinin, hangi sürdürülebilirlik amaçlarına yoğunlaştıklarının tespit edilmesi amaçlanmış ve belediyelerin web siteleri üzerinden içerik analizi tekniğinin kullanımıyla bir inceleme yapılmıştır. Elde edilen bulgular, belediyelerin sürdürülebilirlik amaçlarına yönelik faaliyetler gerçekleştirdiklerine işaret etmiş; sürdürülebilirlik uygulamalarında çoğunlukla açlığın sona erdirilmesi, yoksulluğun bitirilmesi, sağlık ve nitelikli yaşam ile kaliteli eğitim amaçlarına yoğunlaşıldığı tespit edilmiştir.

Objetivou-se identificar e comparar fatores associados à prática do comer consciente e sua relação com a composição corporal nas diferentes fases da vida. Foram avaliados os dados antropométricos e os resultados de dois questionários (Mindful Eating Questionnaire - MEQ e o Emotional Eater Questionnaire - EEQ) de funcionários de uma instituição de ensino superior divididos e classificados em adultos jovens ou em processo de envelhecimento e por gênero. Como resultados, os adultos em processo de envelhecimento de ambos os gêneros e jovens do gênero masculino foram os que apresentaram valores maiores de IMC e RCQ. Apenas adultas jovens foram classificadas como comedoras emocionais. A análise do MEQ mostrou que a distração e as questões emocionais tiveram maior influência na alimentação de adultos jovens. Já na correlação dos dados antropométricos com o EEQ, não houve significância estatística que justificasse o aumento do IMC com o comer emocional do indivíduo. Conclui-se ser necessário que mais pesquisas sejam realizadas para afirmar ou rebater o conceito de que o mindfulness eating possa se relacionar como ferramenta que o indivíduo dispõe para garantir um envelhecimento saudável e uma qualidade de vida adequada quando idoso.

Authors: Krisnawati Krisnawati
Published: April 2022

Penyusutan arsip dalam suatu organisasi atau instansi harus dilakukan untuk tujuan efisiensi dalam kinerja organisasi. Penyusutan arsip juga berfungsi untuk  mengurangi arsip in aktif yang tidak memiliki nilai guna arsip. Penyusutan arsip mempunyai tiga tahapan, yaitu pemindahan arsip, penyerahan dan pemusnahan. Tujuan dari penelitian ini adalah untuk mendeskripsikan proses optimalisasi penyusutan arsip di Dinas Perpustakaan dan Kearsipan, termasuk di dalamnya faktor pendukung dan penghambatnya, serta penyusutan arsip yang berdampak pada kinerja Pemerintah Daerah. Metode penelitian yang digunakan adalah kualitatif, dimana peneliti ikut terlibat secara langsung sebagai instrumen penelitian. Hasil dari penyusutan bisa berupa non arsip yang nantinya bisa dilanjutkan proses pemusnahan arsip, arsip yang masih harus disimpan karena masih dipergunakan dalam kegiatan organisasi meskipun nilai gunanya sudah menurun (arsip dinamis in aktif) ataupun berupa produk arsip statis yang bersifat permanen dan tidak bisa dimusnahkan. Arsip statis inilah yang bisa dijadikan salah satu indikator kinerja bagi  pemerintah daerah sebagai bukti pelaksanaan kegiatan. Semakin banyak arsip statis yang tercipta maka semakin tinggi kinerja pemerintah daerah.

This study is designed to present an agent-based model (ABM) to simulate the interactions between tumor cells and the immune system in the melanoma model. The Myeloid-derived Suppressor Cells (MDSCs) and dendritic cells (DCs) are considered in this model as immunosuppressive and antigen-presenting agents respectively.The animal experiment was performed on 68 B16F10 melanoma tumor-bearing C57BL/6 female mice to collect dynamic data for ABM implementation and validation. Animals were divided into 4 groups; group 1 was control (no treatment) while groups 2 and 3 were treated with DC vaccine and low-dose 5- fluorouracil (5-FU) respectively and group 4 was treated with both DC Vaccine and low-dose of 5-FU. The tumor growth rate, number of MDSC, and presence of CD8+/CD107a+ T cells in the tumor microenvironment were evaluated in each group. Firstly, the tumor cells, the effector immune cells, DCs, and the MDSCs have been considered as the agents of the ABM model and their interaction methods have been extracted from the literatureand implemented in the model. Then, the model parameters were estimated by the dynamic data collected from animal experiments.To validate the ABM model, the simulation results were compared with the real data. The results show that the dynamics of the model agents can mimic the relations among considered immune system components to an emergent outcome compatible with real data. The simplicity of the proposed model can help to understand the results of the combinational therapy and make this model a useful tool for studying different scenarios and assessing the combinational results.Determining the role of each component helps to find critical times during tumor progression and change the tumor and immune system balance in favor of the immune system.

Published: April 2022

Utilizing subunit vaccines is one of the strategies to address influenza infection. Recent innovations have focused on high doses of vaccine antigens and immune enhancers or adjuvants to induce more robust and long-lasting immune responses. Here, an effect of the B cell-activating factor receptor (BAFF-R) to increase the magnitude and durability of immune responses of the recombinant HA1 (rHA1) protein against the H1N1 influenza virus was studied.
The HA1 protein and the effector domain of BAFF-R were expressed in the pET-28a (+) vector. Eight-week-old BALB/c mice were equally grouped into five groups (n=20). The 15 and 25 μg/μL of rHA1 were mixed with 2 μg/μL of rBAFF-R and injected three times for vaccinated groups. Three control groups received normal saline and two concentrations of rHA1. The ability of rBAFF-R in eliciting HA-specific antibody response and stimulating T lymphocyte proliferation to induce the cell-mediated immunity was assayed. Induction of protection was evaluated following the challenge with PR8 strain.
Analysis of immune responses showed that the co-administration of rBAFF-R with rHA1 boosted HI responses to the antigen in mice, whilst it was not able to promote the T cell proliferation responses against influenza. Compared to rHA1alone, the rBAFF-R/rHA1 generated efficient protection for the animals. There were no significant differences in eliciting the immune responses in mice immunized with the lower dose of rHA1 than that with the higher dose.
The data indicate the rBAFF-R can enhance the primary and memory immune responses to protect against influenza infection.

Authors: Wang Le , Chen Mi , Liang Min , Liu Qin , Yao Hua
Published: April 2022

Background: We aimed to investigate the demographic situation relating to people with hearing loss in Xinjiang, the largest province in China. The situation may vary between regions and races.
Methods: We conducted a population-based demographic study. We analyzed data obtained from 3931 people with hearing impairments (i.e., from the Han or Uyghur ethnic groups) including children and adults. We accounted for the survey design and sampling size in order to ensure that estimates were regionally representative. Basic characteristics were determined, and an ethnic distribution analysis was conducted based on age group, level of educational, marital status, and level of disability.
Results: Of the 3931 participants, 2228 (56.68%) were male and 1703 (43.32%) were female. The mean age of the participants was 46.02 (±19.46) years. Most of the participants (26.20%) were in the 45–59 yr age group. Illiterate people constituted the largest group (34.19%) in the Uyghur population, while a substantial proportion of participants of Han nationality had obtained a junior education (28.98%). The number of unmarried people in both ethnic groups accounted for the highest proportion (more than 70%). Grade 3 was the highest grade observed in the Uyghur population (32.35%), while Grade 1 hearing impairments were the most prevalent in the Han population (28.28%).
Conclusion: The difference in basic characteristics between participants of Uyghur and Han ethnicity revealed that different provinces should set different prevention and control targets. Different policy measures should be taken to allocate medical resources and provide rehabilitation services to assist people with hearing impairments in Xinjiang, China.

Published: April 2022

Background: We aimed to investigate the efficiency of neat polyacrylonitrile (PAN) nanofibers and photocatalytic PAN/TiO2 nanofibers for removal of airborne microorganisms.
Methods: Nanofibers were fabricated from 16 wt% of PAN dissolved in dimethyl formamide through the electrospinning technique. The efficiency of media for removal of Staphylococcus epidermidis and Bacillus subtilis was investigated at different conditions such as face velocity, relative humidity, air temperature and UVC radiation intensity. as face velocity (0.1 and 0.3 m/s), relative humidity (35±5% and 60±5%), air temperature (22±3 °C and 30±3 °C) and the UVC radiation intensity (dark, 1±0.09 mW/cm2 and 1.8±0.07 mW/cm2) using air sampling from upstream and downstream of media by cascade impactor containing blood agar culture medium.
Results: The mean diameter of electrospun fibers and coefficient of variation were 194 nm and 15%, respectively. The amount of immobilized TiO2 on the filter was 620±6.56 mg/m2. Photocatalytic nanofiber filter media presented the best performance for removal of airborne B. subtilis at 60±5% relative humidity, 0.1 m/s face velocity, air temperature 22 °C, and 1.8 ± 0.07 mW/cm2 UVC radiation.
Conclusion: The filtration efficiency of photocatalytic media was significantly higher than neat ones. Lower efficiency of media was found in the higher air velocity for all bioaerosols. High UVC radiation intensity increased filtration efficiency. Moreover, the increase in air temperature and relative humidity (except for TiO2-coated media under UVC radiation) did not significantly affect the filtration efficiency of all media.

Background: B-cell lymphoma 2 (BCL-2) and BCL-2 associated X (BAX) polymorphisms are important in the apoptosis process, response to treatment and survival in Acute Lymphoblastic Leukemia (ALL) patients. We aimed to investigate the effect of these genes with other predictors corresponding to the survival of ALL patients with an appropriate frailty survival model.
Methods: Our study was performed in 2020 on sixty-two cases of childhood aged 3-16 (year) with ALL disease who were selected by convenience sampling from the two hospitals of Tabriz, Iran. RFLPPCR method was used for genotyping the promoter region of the BAX and BCL-2 genes. We used different frailty survival models, to control heterogeneity between individuals due to unmeasured factors affecting their survival. All analyses were implemented using Stata 16.
Results:  Based on the result of log-logistic model along with frailty gamma, the proportional odds (standard error) of survival for a CC allele of BCL-2 patient compared to a AA allele patient were 6.0 (1.47); P<0.001 and for a AC of BCL-2 allele patient were 0.57 (1.23); P=0.009. Patients with AG allele of BAX had 2.05 (1.26) times greater odds of surviving than a AA allele patient (P=0.003). The odds of survival of patients with abnormal white blood cell (WBC) were 92% less than normal WBC (P<0.001).
Conclusion: With controlling unmeasured factors affecting, the BCL-2 and BAX genes promoter polymorphism are effective in the survival rates for ALL.

Published: April 2022

In recent years, conventional model-based motion control has become more challenging owing to the continuously increasing complexity of areas in which robots must operate and navigate. A promising approach for solving this issue is by employing interaction-based robotics, which includes behavior-based robotics, morphological computations, and soft robotics that generate control and computation functions based on interactions between the robot body and environment. These control strategies, which incorporate the diverse dynamics of the environment to generate control and computation functions, may alleviate the limitations imposed by the finite physical and computational resources of conventional robots. However, current interaction-based robots can only perform a limited number of actions compared with conventional robots. To increase the diversity of behaviors generated from body–environment interactions, a robotic body design methodology that can generate appropriate behaviors depending on the various situations and environmental stimuli that arise from them is necessitated. Electronics-free robotics is reviewed herein as a paradigm for designing robots with control and computing functions in each part of the body. In electronics-free robotics, instead of using electrical sensors or computers, a control system is constructed based on only mechanical or chemical reactions. Robotic bodies fabricated using this approach do not require bulky electrical wiring or peripheral circuits and can perform control and computational functions by obtaining energy from a central source. Therefore, by distributing these electronics-free controllers throughout the body, we hope to design autonomous and highly decentralized robotic bodies than can generate various behaviors in response to environmental stimuli. This new paradigm of designing and controlling robot bodies can enable realization of completely electronics-free robots as well as expand the range of conventional electronics-based robot designs.

One of the goals of soft robotics is to implement intelligent functions capable of processing complex information in soft materials. This is a noble goal, and we already have a familiar example, albeit not an artificial one, in a living organism. We believe that the intelligent biological elements acquired through the evolutionary process, which do not require an electricity supply or CPU, can be used for soft robotics. In this letter, we introduce three biological elements: proteins, squid, and nematodes, which show temporal or special patterns. We then discuss an attempt to apply them to soft robotics.

Authors: Arai Shunto ,   The University of Tokyo  7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8656, Japan
Published: April 2022

In this study, we developed environmental gas sensors based on bilayer-type organic semiconductors. The number of stacked molecular bilayers was controlled through a solution-based approach. In particular, single molecular bilayers (SMBs) were produced through a geometrical frustration method that can effectively suppress the multiple stacking of bilayers. The layer number-controlled films were utilized to form thin-film transistors (TFTs) to detect the moisture in the air. We revealed that the sensitivity was enhanced in the SMB-based TFTs compared with the TFTs with thicker active layers. These findings are expected to facilitate a new route for producing flexible and lightweight chemical sensors.

Actuators are usually driven in a uniaxial direction, which limits their ability to be driven with multiple degrees of freedom. In this study, we propose an actuator that is not limited to a uniaxial direction. We developed a polyvinyl chloride gel actuator with a particulate structure. The actuator can change its surface shape by displacing each particle in the structure. As the first step in this experiment, each particle was displaced independently, by applying a voltage to the anode to change the actuator’s surface into an uneven shape.

Cursorial quadrupeds have different connections to the trunk for forelimbs and hindlimbs: a flexible connection through the muscles to the forelimb, and a secure connection through the hip joint to the hindlimb. Although anatomical and biological studies have described the structure and behavior of cursorial quadrupeds by focusing on flexible shoulders, the functionality of the flexible shoulder remains unclear. In this study, we first survey the anatomical and biological studies. Second, we introduce our robotics studies, which focus on flexible connections for proximal limb joints. Further, we discuss future directions for extracting a design principle based on complex animal body structures, and we suggest the potential for interdisciplinary research between anatomy and soft robotics.

Structural changes during the drawing and shrinking of linear low-density polyethylene (LLDPE) film are analyzed through in-situ X-ray measurements. A synchrotron radiation source enables simultaneous analyses combining small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD). During drawing, the original unoriented SAXS and WAXD patterns transformed into line and spot patterns, indicating the orientation of both lamellar stacking and the molecular axis along the drawing direction. During the subsequent shrinking these patterns are retained, suggesting the tilted lamellar and molecular chains. A possible model for structural changes indicates that tie molecules between lamellae effectively transmit drawing and shrinking stresses, which contributes to desirable actuation properties.

Pneumatic soft actuators exhibit both passive flexibility from the casing and active flexibility from pressurizing and depressurizing. These actuators are expected to be human-friendly and are often used in nursing and medical situations because they allow access to soft systems through control of the internal air pressure. The current design of pneumatic soft actuators has two technical points of interest: the control method for the drive direction and the operating pressure level. An actuator that addresses these points is required. In this study, a pneumatic soft actuator with a silicone rubber casing – called a sponge core soft rubber actuator (SCSRA) – is developed to solve these problems. SCSRAs can perform various functions by changing the bonding state of the silicon film. Thus, a large stroke can be achieved in a low-pressure area of ≤ 30 Pa, and the driving system can be controlled by peeling off and bonding the silicon film. We clarified the expansion and stiffness characteristics of the “bonded SCSRA” and “peeled SCSRA” when unpressurized and pressurized and measured the grip strength when walking in shoes with protrusions on the insole and single-tooth sandals with protrusions on the sole as example applications of the sensing ability.

In this study, we developed a variable-stiffness and deformable link using shape-memory material and the jamming transition phenomenon. Above its glass transition temperature (Tg), a shape-memory polymer (SMP) can be deformed by applying a small load. SMPs maintain the deformed shape after they have been cooled below Tg, and they return to their original shape when heated above Tg. The reversible change in the elastic modulus between the glassy and rubbery states of SMPs can be on the order of 100–1000 times. We exploited the characteristics of SMPs to develop robot components with variable stiffness and sensitivity. The jamming transition phenomenon for granular material has been widely used as a method to change the stiffness of robots. This phenomenon is the change from fluid-like to solid-like conditions by removing air from a space containing particles. In this study, we developed a variable-stiffness link by combining the SMP and the jamming transition phenomenon. Moreover, by replacing the SMP with shape-memory alloys (SMAs), whose recovery force and elastic modulus are larger than those of SMPs, we prepared a second prototype with variable stiffness. We evaluated the performance of both prototypes, using the SMP or the SMA, with experiments and confirmed the motion principle of the proposed link (e.g., shape recovery and shape fixity). Moreover, it was confirmed that the stiffness of these links can be changed among four states.

El vulcanismo en el cine
Authors: Martínez Parra Marc
Published: April 2022

Como recurso argumental o temático, o bien como soporte, el cine ha empleado conceptos de la vulcanología, desarrollando historias enmarcadas, en diversos géneros cinematográficos, especialmente el cine de catástrofes, de aventuras y el documental, con filmes basados en sucesos reales o bien ficticios, como las acaecidos en las ciudades de Pompeya y Dante’s Peak, respectivamente. Son filmes en lo que los efectos especiales tienen gran importancia. También el género documental, tanto en noticiarios como en largometrajes, a causa de la espectacularidad de las imágenes de la naturaleza más primigenia, ha tenido en el vulcanismo un imán en cuanto a interés del público.
ANÁLISIS 3D DEL RETROCABALGAMIENTO DE SAN VICENTE (BORDE SUR DEL SISTEMA CENTRAL) MEDIANTE DATOS OBTENIDOS POR DRONE
Authors: Comas López Nuria
Published: April 2022

En este trabajo se presenta un análisis estructural y geomorfológico del retrocabalgamiento de San Vicente, un gran ejemplo de acomodación de la deformación alpina en el borde sur del Sistema Central Hispano-Portugués (SPCS) en su contacto con la cuenca Cenozoica de Madrid. Este conforma un par anticlinal-sinclinal que, junto al cabalgamiento al N del sinclinal, dibujan una estructura en pop-down muy apretada con transportes tectónicos hacia el NO, retrovergentes respecto al cabalgamiento principal. El flujo de trabajo se ha basado en el empleo de drones para la captura de imágenes, seguida de una reconstrucción en 3D para su posterior interpretación, cuyo fin es la obtención un modelo geológico en 3D. Los resultados confirman que esta metodología puede ser un complemento a los estudios cartográficos tradicionales que aporta nuevas soluciones a las problemáticas heredadas de la perspectiva en 2D, la inaccesibilidad a determinadas zonas o incluso a la falta de tiempo o medios para realizar una cartografía de calidad.

Authors: Kailani Ahmad , Rafidiyah Dina
Published: April 2022

This research reports on the results of an interview study of nine English teachers at vocational schools (VS) in Indonesia. The study aimed to explore English teachers’ voices of  the revitalization program at VS’s in Indonesia. The study shed the light on two major issues of English teaching and learning at VS’s concerning revitalization program implementation.  The two main themes were the use of specific technology in the language classroom and video mediated language learning in vocational English classroom.The results indicated that most of teachers more preferably used social media for teaching than utilizing a learning management system (LMS). Teachers have used video mediated teaching method for their English classes either self-production videos or a ready-made video from the internet. English for business was also introduced to students to equip them with basic knowledge for a job selection The results have implications for  the implementation of revitalization programs in particular the revitalization of vocational English teaching and learning at SMK.
