Materials and methods. The participants were 40 elderly females aged 62 to 76. They were selected by systematic random sampling, using balance score as the criterion. They were divided into two equal groups of 20 people each, namely, the Tai Chi and resistance band training (TCR) experimental group was trained for 8 weeks, 3 days a week for 60 minutes each day, and the control group (C) was not trained. The participants volunteered to sign the consent forms to participate in this research. Quantitative data was collected by measuring balance, hand muscle strength, and leg muscle strength. Qualitative data was collected via interviews and participant observation.
Results. The research found that (1) balance, hand muscle strength, and leg muscle strength were no different before the training. Post-training of Tai Chi and resistance band trainings (TCR) of the 4th and the 8th weeks, the experimental group had the mean of balance, hand muscle strength, and leg muscle strength better than the pre-training and the differences between the experimental group and the control group were statistically significant (p<0.05). (2) The experimental group had balance, strength, good flexibility, relaxed body and good mental health.
Conclusions. As regards the benefits to the physical fitness, tai chi and resistance band training (TCR) and combination exercise improve balance, hand muscle strength and leg muscle strength. This makes the elderly have good health and physical fitness.

Authors: Genç Hazal , Tahmaz Tuğçe , Akgül Onur
Published: December 2022

Background. Resistance-trained males aim to increase their overall health, strength and fitness level. Many resistance-trained males aiming to increase their strength neglect the muscles that stabilize the scapular and glenohumeral joints. The shoulder joint is among the most frequently injured areas in resistance-trained males. In addition, strength training displays different effects in young and old individuals.
The study purpose was to investigate the effects of stability and mobility exercises on range of motion, posture and body awareness in resistance-trained males with shoulder immobility.
Materials and methods.  Thirty-two resistance-trained males diagnosed with shoulder immobility were divided into two groups according to their age ranges (G1: Adult, G2: Young Adult).  The program consisting of mobility and stability exercises was applied 3 days a week for 8 weeks. The participants were evaluated with a universal goniometer, the New York Posture Rating, and the Body Awareness Questionnaire before and after the treatment lasting 8 weeks.
Results. Following the 8-week treatment, improvements in body awareness and range of motion were observed in all participants (p≤0.05). There were improvements in the scores of the New York Posture Rating and Body Awareness Questionnaire in both groups, but they were not statistically significant (p≥0.05).
Conclusions. An exercise program combining stability and mobility exercises was applied to resistance-trained males with shoulder immobility and it was observed to have positive effects on the range of motion of the joint, body awareness and posture. We are of the opinion that various types of exercise should be implemented when planning exercise programs.

The purpose of the study was to determine the state of performance of motor actions by girls with different handedness, which establishes a valid program for each age period of 3–5 years. Materials and methods. Sixty girls took part in the study (compared with the right-, left-hand preference, and ambidexterity), each attended a preschool, and at the time of the study, the age of each was within the range of 3 years 5 months 2 days to 3 years 5 months and 29 days. To obtain the necessary data, motor actions determined by the current child development program in the preschool period were used. The quality of the girls' performance of each defined motor action was assessed, and the procedure took place in January of each new school year, that is, when the girls were first 3 years old, then 4 and 5 years old. Results. Each age of the period of 3–5 years is marked by handedness-related features of development and manifestation of the motor function of girls when performing motor actions with their hands. At the same time, the majority of motor actions were performed by the girls of each sample with a score lower than the maximum score. This does not contribute to the intensive development of the motor function of girls, which differs from the task defined by the current program for preschool education institutions. Comparing the results of girls with different handedness, it was found that in most motor actions, the scores obtained for performance differ by a statistically significant amount, and at each age of the studied period. Conclusions. Establishing features in the quality of performance of motor actions by girls with different handedness at each age period of 3–5 years is an important task. To increase the effectiveness of the educational process, the teacher needs to pay more attention to the study of those motor actions that were evaluated with low scores in girls with a certain preferred hand.

Study purpose. The objective of the study was to assess the relationship between quality of life and physical activity level and family well-being.

Materials and Methods. The International Physical Activity Questionnaire (IPAQ) was used to assess parental physical activity. The quality of life was assessed with the Short Form (SF-36) Health Survey Questionnaire. The data obtained were processed using cluster and correlation analysis, and descriptive statistics. The study involved 106 young adults (married couples), who were parents of preschool and primary school-aged children.

Results. An assessment of parental physical activity showed that 62.3% of the respondents had a low level of physical activity and 37.7% had a moderate level, whereas no individuals with a high level of physical activity were found. Families with children were divided into clusters with the k-means method according to the level of physical activity: Cluster 1 included families with a low level of physical activity; and Cluster 2 included the families with a moderate level of physical activity. The results of the study confirmed the relationship between the quality of life and the level of physical activity and family well-being. It was found that all the quality of life components of the study participants with a moderate level of physical activity are significantly higher (р<0.05) than those of the participants with a low level of physical activity. Correlation analysis of family well-being and quality of life indicators revealed significant relationships (p<0.05) between physical functioning, physical role functioning, vitality, and mental health.

Conclusions. The direct statistically significant relationship between family well-being score and quality of life components of the respondents was demonstrated.

Bodies that Speak
Authors: Berio Maria Eugenia
Published: December 2022

The present article examines the treatment of spatial corporeality in Doris Lessing’s novella “The Eye of God in Paradise” (1957) set in Germany in the aftermath of the Second World War. Even though Lessing’s works have been studied from different perspectives—as the abundant critical studies show—, spatial corporeality has not been analysed before. This paper argues that the characters’ bodies, insofar as physical spaces of flesh and blood that are lived and where power is exerted, represent the trauma encountered by countless anonymous people who suffered due to the horrors of the war and who have only been made visible by the author’s skilled pen. By highlighting the corporeal spatiality in its physical, psychological, and sociohistorical division, Lessing has brought to the fore the intense suffering of unknown people, to give them identity as well as visibility and transform them into a locus of contesting power relations.

Currently, the solar PV power extraction technology is undergoing significant improvement. Towards this, the paper proposed the design for a photovoltaic (PV) array and the output performance of a photovoltaic system under the influence of irradiance. To achieve this, the design for improved incremental and conductance fast tracking INC -FI based MPPT technique for solar PV system has been presented. The purpose of employing the improved INC -FI technique is to improve the efficiency of the system. The accuracy and performance of the proposed INC -FI method was increased due to its better tracking capability by utilizing variable ΔD for tracking the MPP in comparison to the conventional INC method at variable temperature while keeping the irradiance constant. Further, the results of the proposed method were compared with the conventional method where the INC -FI based technique outperforms the conventional INC method in terms of better accuracy. For the irradiance with 800w/m2, the achieved MPPT efficiency was 58.21 for conventional method and 80.53 for the improved technique. It was also noted that the tracking efficiency of the conventional method was 84.39 as compared to 99.92 for the proposed INC -FI technique in terms of MPPT efficiency at the irradiance of 1000w/m2. Furthermore, the improved method delivered fast tracking ability of the MPPT system with a time of less than 10 s(approx.). The MATLAB Simulink platform was utilized for designing the proposed technique. In future, the proposed INC based technique would be implemented on hardware for better outcomes and validation.

Change in activity patterns and travel behaviour were seen worldwide as a response to the COVID-19 pandemic. This is mainly due to the restrictive measures imposed by the government and perception of own safety or commitment in reducing the spread of the disease. However, with or without the restrictive measures, people still have various needs to travel. Thus, this study was initiated to understand the changes in travel behaviour due to the COVID-19 pandemic. An online questionnaire survey, including questions related to purpose of travel, transport mode choice, distance and frequency of trip was conducted. Findings from this study revealed that there is a significant change in activity pattern and travel behaviour, before and during the COVID-19 pandemic. Based on the 460 responses received, it is known that mode shifts, from public transportation to private vehicles, occurred mainly due to pandemic related concerns. This study reveals that people perceived public transportation as a potential risk for exposure of the COVID-19 virus, while private vehicles, bicycles and walking are viewed as the safest mode of transport during the pandemic. Gender, age group, vehicle ownership, marital status and purpose of travelling had significant impact on the mode choice during the pandemic. Based on these findings, it is hoped that rail and bus transport service providers will be able to plan measures and further encourage the usage of the rail and bus transport services post-pandemic.

M303 is a corrosion resistant martensitic chromium steel offering excellent toughness, corrosion, and wear resistance, characterized by improved machinability and polish ability. It is widely utilized in industries such as in mould and die making, machinery and automotive equipment, bearing housing, and tooling. Recently, this material has also been used in locomotive bearing housing. This paper presents surface roughness achieved in the turning process of M303 in dry cutting condition using coated and uncoated carbide tools. The turning parameters included a high cutting speed regime (260-340 m/min) and feed rate at 0.1-0.2 mm/rev, suitable for the finishing process. The experiment was conducted according to the Taguchi method (L18). Average surface roughness (Ra) was in the range of 0.395-1.356 μm, in which a mirror finish was achieved for certain cutting conditions that could eliminate the grinding process. Results of surface roughness were analysed using Analysis of Variance (ANOVA) for linear models and revealed that feed rate is the main significant factor contributing to surface roughness, followed by type of cutting tool, and cutting speed. These findings show that good and dition, therefore it is recommended to eliminate the acceptable Ra values for M303 turning are obtained in dry con use of flooding condition as normally practiced in the industry.

Penjagaan anak selepas perceraian adalah satu cabaran buat ibu bapa. Semasa dalam perkahwinan ibu bapa berkongsi tanggungjawab keibubapaan dalam pengasuhan, penjagaan, pendidikan dan kebajikan anak namun tanggungjawab keibubapaan ini akan menjadi satu isu sosial dan perundangan apabila sudah bercerai. Artikel ini akan memfokuskan kepada tiga objektif. Pertama untuk menganalisis peruntukkan undang-undang berkaitan penjagaan bersama menurut undang-undang syariah, kedua menganalisis konsep penjagaan bersama dan perkongsian keibubapaan dan ketiga, untuk membandingkan konsep dan perundangan perkongsian keibubapaan antara negara Sweden dan Australia. Pemilihan dua negara Sweden dan Australia berdasarkan undang-undang sedia ada dan polisi yang diaplikasikan di negara tersebut. Secara asasnya kajian ini berbentuk kajian doktrinal melalui analisis kualitatif. Analisis dokumentari dilakukan ke atas data dan teori dari bahan yang terpilih termasuk jurnal artikel, buku, dan statut. Kesemua data ini diperolehi melalui kajian kepustakaan. Dapatan dari kajian ini menunjukkan bahawa jagaan bersama melalui konsep perkongsian keibubapaan lebih memberikan hak dan menjamin kepentingan kanak-kanak seterusnya menjamin kelangsungan tanggungjawab berterusan ibu bapa selepas perceraian berbanding jagaan sebelah pihak. Oleh itu adalah menjadi satu keperluan untuk penggubal undang-undang keluarga Islam di Malaysia menyemak semua peruntukkan sedia ada berkaitan penjagaan anak selaras dengan prinsip ‘kepentingan terbaik kanak-kanak’sekaligus memenuhi matlamat 16, Matlamat Pembangunan Mampan (SDG) 2030.

Published: December 2022

Peningkatan arus pemodenan pada hari ini telah menjadi pemangkin kepada kenaikan kadar jenayah siber di Malaysia. Kemudahan dan kecanggihan peranti-peranti elektronik telah menyebabkan alatan ini mempunyai kepentingan tersendiri terutamanya dalam memberikan input dan petunjuk berharga sebagai suatu bentuk keterangan dalam kes-kes di mahkamah. Namun begitu, pengenalan keterangan elektronik sebagai keterangan terutamanya dalam kes-kes jenayah siber telah menjadi suatu topik hangat dalam kalangan pengamal undang-undang kerana pelbagai isu berkenaan dengan penerimaan keterangan elektronik seperti isu kerelevanan dan kebolehterimaan, isu definisi-definisi penting tentang dokumen yang dikeluarkan oleh komputer, isu peruntukan-peruntukan undang-undang yang mengawal selia keterangan ini dan sebagainya telah mulai timbul. Oleh hal yang demikian, penyelidikan ini telah dilaksanakan bagi mengetahui dengan lebih lanjut mengenai kebolehterimaan, kerelevanan dan pembuktian jenayah siber di mahkamah serta peruntukan undang-undang yang berkaitan, mengenal pasti dan menganalisis masalah-masalah berbangkit dari segi undang-undang mengenai keterangan ini, serta memberikan cadangan-cadangan bagi masalah-masalah tersebut. Bagi menjayakan kajian ini, pendekatan kualitatif yang bersifat doktrinal telah digunakan. Sumber-sumber primer dan sekunder seperti statut undang-undang, kes-kes mahkamah, artikel dan makalah undang-undang telah dirujuk dengan mendalam. Bagi menganalisis data-data yang diperoleh pula, kaedah sejarah, analisis dan kritis telah dijalankan. Secara amnya, kajian ini telah mendapati bahawa seksyen-seksyen 90A, 90B, 90C dan 114A Akta Keterangan 1950 merupakan sumber-sumber undang-undang utama yang membolehkan pengemukaan keterangan elektronik dapat dilakukan di mahkamah. Sungguhpun begitu, keterangan ini hanya boleh dikemukakan dan diterima sekiranya konsep kerelevanan dan kebolehterimaan telah dipenuhi terlebih dahulu. Antara cadangan penambahbaikan yang telah diutarakan dalam kajian ini ialah ketulenan, ketepatan dan keselamatan sesuatu keterangan elektronik hendaklah dipastikan terlebih dahulu sebelum keterangan ini diterima oleh mahkamah dan penetapan tafsiran yang jelas bagi dokumen yang dikeluarkan oleh komputer.

coto de San Julián de Samos: la construcción de un territorio monástico entre los siglos X y XI
Authors: CARVAJAL CASTRO ALVARO
Published: December 2022

La conformación del coto de Samos es uno de los más singulares procesos de construcción territorial en el noroeste de la península ibérica en época altomedieval. La documentación prima las iniciativas regias como principal factor detrás de la concesión original y de sus sucesivas ampliaciones. Las fuentes, sin embargo, revelan que el coto se desarrolló en una zona densamente poblada y con presencia de actores de distinta condición que interaccionaban de manera diversa con el monasterio en torno a cuestiones relacionadas con la apropiación de la tierra y el control del territorio. Este artículo, basado en un análisis sistemático de la documentación disponible para los espacios englobados en el coto antes del siglo XII, atiende al conjunto de actores, iniciativas y relaciones sociales que pudieran determinar, en cada momento, cómo se concretaba espacialmente esa particular forma de control territorial que Samos reivindicaba sobre su entorno.
Globe Pulsed Field System for High-definition Mapping and Ablation for Atrial Fibrillation

Published: December 2022

Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation ablation. Radiofrequency ablation has been the most common source of energy used to achieve PVI until now. In recent years, cryoballoon ablation has gained popularity due to its ability to perform PVI in a ‘single-shot’ fashion. In both cases (radiofrequency and cryoablation), the main limitation is their inability to achieve durable lesions without causing collateral damage to adjacent structures. In contrast, pulsed electric field (PEF) ablation is a non-thermal energy source that causes cell apoptosis by applying an electric current to the tissue. Lesions created by a field of energy seem to be more contiguous than traditional ablation, and the risk of damage to adjacent tissues is largely avoided due to the properties of the tissues and electrical fields. In recent years, new catheters capable of delivering PEF have been developed and are now undergoing clinical testing. In this article, we describe a complete solution for PVI: a single multielectrode catheter with 3D mapping capabilities that can deliver PEF in a single-shot PVI fashion with targeting beyond the pulmonary veins.

Bu araştırmanın amacı, örgüt kültürü ve örgütsel demokrasinin örgütsel sessizlik üzerindeki etkisini tespit etmektir. Bu doğrultuda nicel bir araştırma yapılmıştır. Anket tekniğinden yararlanılarak veriler toplanmıştır. Veriler ilk olarak yapısal eşitlik modellemesi ile uyum ve güvenilirlik yönünden analiz edilmiştir. Hipotez testi için çoklu regresyon analizi yapılmıştır. Analizler sonucunda; klan ve adhokrasi kültürünün örgütsel sessizlik üzerinde negatif yönlü anlamlı etkisi olduğu görülmüştür. Diğer taraftan pazar kültürünün örgütsel sessizliği pozitif yönlü ve anlamlı etkilediği belirlenmiştir. Bir diğer analizde; örgütsel demokrasinin şeffaflık ve eşitlik boyutlarının örgütsel sessizliği negatif yönlü anlamlı etkilediği tespit edilmiştir. Araştırma sonuçlarına göre; klan ve adhokrasi kültürü örgütsel sessizliği azaltırken, pazar kültürü artırmaktadır. Bir diğer sonuç olarak; örgütlerde şeffaflık ve eşitlik algısının azalması sessizlik davranışını artırmaktadır. Son olarak örgütsel demokrasinin örgüt kültürü tarafından önemli ölçü etkilendiği tespit edilmiştir.

Afganistan’da Ulus İnşa Süreci ve Çöküşü
Authors: SÜRÜCÜOĞLU Orkun
Published: December 2022

11 Eylül saldırılarının ardından Afganistan’a askeri bir müdahale gerçekleştiren ABD, Taliban yönetimini devirdikten sonra ülkede bir ulus inşa süreci başlatarak yeni bir rejim kurulmasına öncülük etmiş ve yaklaşık 20 yıl boyunca bu rejime siyasi, askeri ve ekonomik destek vermiştir. Ancak gerek istikrarlı ve dış yardıma bağlı olmayan bir yapının tesis edilememesi gerekse de savaşın maliyetinin ABD ekonomisine getirdiği yük, Amerikan askerlerinin ülkeden çekilmesine yol açmıştır. Bu makalenin amacı Afganistan’daki rejime verilen tüm dış desteğe rağmen ulus inşa sürecinin bu kadar çabuk çökebilmesinin nedenlerini tartışmaktır. Bu doğrultuda Afgan halkının ihtiyaç ve talepleri ile uygulamaya koyulan ulus inşa projesinin bu ihtiyaç ve taleplere uyumu irdelenecektir. Bu bağlamda, öncelikle Afganistan’ın toplumsal yapısı belirli bir tarihsel arka plan çerçevesinde ortaya konulacak, ardından ABD öncülüğündeki ulus inşa sürecinin siyasi, iktisadi ve güvenlik boyutları uygulamadaki sorunlarıyla birlikte ele alınacaktır.

Authors: Farzi Reza , Fellus Olga
Published: December 2022

Students at Canadian universities who do not meet their program-specific language and academic requirements may be admitted to their programs with a condition to enrol in an intensive language program. While, in general, university-based language intensive programs aim to help students improve their general and academic language proficiency, our focus is to specifically enhance, foster, and render visible students’ academic literacy and academic readiness. We aim to bring forth some of the intricacies and complexities of curriculum design that are embedded within current theory and practice and address needs based nuances in teaching academic English to international students. In this article, we use a multi-dimensional framework to describe a case study of an academic institution that offers an English Intensive Program. curriculum. This program allows for, inter alia, the incorporation of multiple literacies including extra curricular activities to promote the development of a wide array of academic literacies in students enrolled in the English Intensive Program. Following a description of the theoretical framework, we discuss practical implications of including theory driven academic literacies into intensive language program curricula for different stakeholders.

Authors: Salazar-Xirinachs José Manuel
Published: December 2022

El desarrollo del sector de dispositivos médicos (DMs) en Costa Rica obedece a la combinación del dinamismo del sector privado junto con la adopción de una política de desarrollo productivo (PDP) exitosa. En 2020 el total de exportaciones de DMs llegó a US$ 3.935 millones, a partir de solo US$ 1.300 millones en 2011, convirtiéndose en el segundo mayor exportador de LAC. El crecimiento ha estado impulsado por: 1) la política explícita e integral para atraer, retener y expandir a las OEM y su cadena de suplidores, con una promoción y acompañamiento institucional cercano a lo largo de 20 años; 2) la alineación de las metodologías de CINDE con las mejores prácticas internacionales en todo el ciclo de atracción, entrada y establecimiento, retención y expansión, encadenamientos y manejo de spillovers; 3) el trabajo de PROCOMER en las áreas críticas de encadenamientos y de aumento de las capacidades exportadoras de las empresas, con un enfoque integral de expansión en al menos tres niveles: i) líneas de manufactura en plantas ya existentes; ii) hacia servicios como shared services y BPO; y iii) hacia ID.; 4) el desarrollo del talento humano (competencias y bilingüismo) con una oferta académica respondiendo a las necesidades de crecimiento del sector; y 5) una nueva etapa de gobernanza bajo el enfoque de clúster y un fortalecimiento del sector académico para seguir ascendiendo en la cadena de valor y convertir a Costa Rica en un Life-Centered Hub.
Colaboración nacional-subnacional como factor de competitividad en la atracción y facilitación de inversiones
Authors: Taylhardat Adolfo
Published: December 2022

La competencia por la atracción de inversión extranjera directa (IED) se intensificó a partir del 2020 debido a la drástica caída de los flujos de IED y al incremento en el número de agencias promoviendo las inversiones. En este entorno competitivo resulta fundamental para las agencias de promoción de inversiones (APIs) repensar sus estrategias y reforzar su capacidad de ejecución. Un reciente estudio del BID, Making the Invisible Visible, reveló que las APIs nacionales que coexisten y colaboran con APIs subnacionales son más efectivas. Esta nota se centra en el análisis de modelos de colaboración nacional-subnacional actualmente vigentes en cinco países con distinto grado de desarrollo/trayectoria con el objeto de capturar una diversidad de experiencias institucionales. Los modelos son analizados desde la perspectiva de los protocolos y acuerdos de colaboración firmados entre los diferentes órganos, los componentes organizacionales de las agencias, las herramientas de colaboración digitales y no-digitales, los recursos humanos y financieros, así como la cultura de relacionamiento interinstitucional. Las conclusiones destacan cuatro puntos: 1) el país como punta de lanza para la atracción de IED por la fuerza de su marca internacional; 2) el establecimiento de protocolos de colaboración alineados con el nivel de descentralización política; 3) la gestión de leads de inversión generalmente se mantiene a nivel de la API nacional; y 4) la colaboración se apalanca en herramientas tecnológicas.
Modified Ant Colony Optimization for Human Recognition in Videos of Low Resolution
Authors: Ranganarayana Katakam , Rao Gurrala Venkateswara
Published: December 2022

Privacy protections for people filmed in public settings is a prerequisite to widespread camera use. For this reason, low-resolution videos are used from which specific people can be reliably obscured. Since the human region in low-resolution videos comprises of so few pixels and so little information, human detection is more challenging there than it is in high-resolution videos. With the current state of affairs, one of the most important challenges is tracking a target from lower resolution movies. Identification or monitoring of persons in low-resolution movies has become a common issue in many domains due to a lack of appropriate data. This study presents a novel people-detection algorithm that makes use of low-resolution film to overcome the aforementioned problem. In the first stage, a three-step procedure is executed, the video data gathered from low-resolution videos from various form of data is considered. The captured video is separated into frames and transformed from RGB to gray-scale. Local Binary Pattern (LBP) method is used in the second phase to accomplish background subtraction. Thirdly the feature extraction is performed in which histogram of optical flow (HOF)and some of the features are extracted in the form of eigen values. Finally these features are optimized using Modified Ant Colony Optimization (MACO) model to remove the unwanted features and select global features. Finally, classification operation is performed using Support Vector Machine (SVM) classifier to recognize the person from lower resolution videos. The results obtained using the implemented MACO-SVM obtains good results when compared with existing techniques with rate of accuracy 91.46% for soccer dataset, 90.8% for KTH dataset and 89.75% accuracy using VIRAT dataset.
