Abstract Today's sailing visualization instruments struggle to cope with the increasing number of onboard sensors, automation, artificial intelligence, and the high dynamism of the crew. Current solutions scatter multiple displays all over the boat, both inside and outside,
potentially reducing usability and increasing costs. This work presents a systematic review of augmented reality (AR) as an integral solution for sailing data visualization, which revealed four scientific papers and eight commercial products. We analyzed the publication type, the AR hardware,
what and how information is presented using AR, the validation method (if present), and the technological readiness. We defined the technical requirements needed for the AR device for sailing and distinguished a first generation of commercial solutions based on head-up displays from a second
one based on proper augmentation with stereo head-mounted displays. The displayed information elements are limited in number and are commonly 2-D graphics (e.g., text and symbols) with a screen-relative frame of reference (as opposed to body- or world-relative). The most visualized elements
are heading (10) followed by wind direction (8), boat speed (7) compass (7), and wind speed (7). We also found that most of the solutions lack critical evaluation. We conclude that AR has the potential to integrate sailing data from different systems and to improve accessibility, situation
awareness, and safety for a large group of users. However, the main limitations are the lack of AR head-mounted displays suitable or adaptable for sailing conditions, an extensive exploration of 3-D interface elements, and an adequate number of usability studies in the scientific literature.

Published: May 2021

Abstract Underwater exploration tasks in a narrow environment have stringent requirements related to the dynamic mode and shell design of underwater submersibles. Specifically, these submersibles should have horizontal maneuverability to move in a narrow environment. A certain
degree of stability in the vertical direction should also be maintained to realize the stability of these submersibles at a certain depth for observation. A disk-shaped shell has the mobility of a spherical shell in the horizontal direction and the stability of a pancake-shaped shell in the
vertical direction. Therefore, a design scheme for a disk-shaped shell of a water-spraying underwater robot was formulated through a comparative analysis of various shell shapes. To achieve movement in different directions, the Fluent fluid simulation software was used to continuously simulate
and optimize these shell shapes. Relevant parameters, such as total pressure and force, that were obtained from the simulation were analyzed through horizontal and vertical comparisons. The maneuverability of the disk-shaped shell on the horizontal plane and its stability on the vertical plane
were subsequently verified. Based on the measured maneuverability, the system of the disk-shaped water-spraying robot was designed, and a movement experiment was conducted to examine the straight and rotational motions of this robot. This study provides new ideas and theoretical support for
designing the shape of submersibles in narrow underwater environments and promotes the development of underwater exploration technologies for narrow spaces.

Abstract Taking the AU5-50 propeller as an example, the detailed process of propeller modeling with atlas method and PropCad is compared. By comparing the auxiliary profiles used for modeling, it is pointed out that the blade model established by PropCad has more complete
features and is not restricted by the propeller type. Besides, to verify the credibility of the PropCad modeling method, simulation analysis is carried out. First, the hybrid mesh and boundary layer mesh are divide for the flow field by integrated computer engineering and manufacturing (ICEM).
Second, grid independence is verified utilizing a multiple reference frame (MRF) model. In the verifying process, three widely used turbulence models are analyzed and compared under advance ratio 0.7, and the results show that the hydrodynamic coefficient error calculated by the shear stress
transport (SST) k-ω model is the smallest. Third, the computational fluid dynamics (CFD) calculation model is determined. The hydrodynamic performance of the propeller at different advance ratios is analyzed, and the CFD calculation results are in good agreement with the open
water test data. Finally, the fluid-solid coupling analysis of the propeller is performed, and it is verified that the stress field of the propeller meets the material strength requirement. Therefore, it is proved to be feasible to conduct propeller modeling with PropCad.

Published: May 2021

Cancer is a problem of both global and local concern. We determined the geo-epidemiological and spatial distribution of the 10 most common cancers in Iran. We used the data of the Iranian Cancer Registry for the year 2014 analysing the prevalence of 112,131 registered cancer cases with the aim of detecting potential geographical underlying causes. The geographic distribution of cancers is reported as standardized incidence rates at the provincial level considering risk with respect to sex and age. A geographical information systems (GIS) approach based on Anselin Local Moran’s index method was used to map clusters and spatial autocorrelation patterns. The mean age of the patients was 55.6 (±17.8) and 61.7 (±18.2) for females and males, respectively, in the database which showed 46.1% (n=51,665) of all cases to be female. Analysis of the spatial distribution of cancers showed significant differences among the different provinces. Stomach and breast cancers were the most prevalent cancers in men and females, respectively. The highest incidence rates of stomach cancer were found in Ardabil and Zanjan provinces, with 48.38 and 48.08 per 100,000 population, respectively, while Tehran and Yazd provinces had the highest incidences of breast cancer, 51.0 and 47.5 per 100,000 population, respectively. Strong clustering patterns for stomach and breast cancers were identified in the north-western provinces and in Semnan Province, respectively. These patterns indicate a diversity of geo-epidemiological contributing factors to cancer incidence in Iran.
Patient Outcomes After Treatment by Athletic Therapy Students
Authors: Lebel Frédérike Berger , DeMont Richard , Eberman Lindsey E. , Dover Geoffrey C.
Published: May 2021

Context

Patient-reported outcome measures (PROMs) should be used in athletic training and athletic therapy but are rarely incorporated in internships. Student-run clinics are common in other health professions and provide effective treatment and valuable learning environments. To our knowledge, no one has evaluated rehabilitation outcomes in patients treated by athletic therapy students (ATSs).

Objective

To measure the improvement in function in injured patients seeking treatment at an ATS clinic.

Design

Cohort study.

Setting

An ATS clinic.

Patients or Other Participants

A total of 59 patients (32 women, age = 33.9 ± 14.7 years; 27 men, age = 38 ± 14.4 years) from the community with a variety of low back, lower extremity, and upper extremity injuries participated.

Main Outcome Measure(s)

At baseline and 6-week follow-up, all patients completed 1 of 3 scales (depending on their injury location) to assess their injured level of function. Scales were the Oswestry Disability Index for low back injuries; Lower Extremity Functional Scale for lower extremity injuries; and Disabilities of the Arm, Shoulder and Hand for upper extremity injuries.

Results

On average, patients received 4.7 ± 1.8 treatments across 48.8 ± 16.1 days. They experienced an increase in function between baseline and follow-up assessments (18.8% ± 20.3%; P < .001, Cohen d = 1.06). Moreover, the amount of functional improvement was clinically meaningful, as it was greater than the minimal clinically important difference for each scale. The efficacy of treatments did not differ according to the internship experiences of the ATSs.

Conclusions

Function improved in patients after treatment delivered by an ATS. Patient-reported outcome measures were useful for the students in monitoring patient improvement, but more research is needed regarding effective treatments for patients with chronic pain. Our results suggested that ATS clinics provide effective treatments for patients, service to the community, and a learning opportunity for students.

The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

Authors: Bharti Abhishek , Singh Harpreet , Singh Deepak , Kumar Vipin
Published: May 2021

Background:

We aimed to find out the overall reported and intended behavior of the general population of India toward mentally ill persons.

Materials and Methods:

Participants were included in an online survey using a nonprobability snowball sampling technique. After taking informed consent, sociodemographic details were recorded, and the “Reported and Intended Behaviour Scale” was administered.

Results:

Out of 818 responses, 684 responses were eligible for study after exclusion. The mean age (standard deviation) of the study population was 31.01 (7.79) years. Maximum participants reported that they did not live (76.6%), did not work (75.7%), did not live nearby (66.4 %), or have not had a close friend (79.8%) with mental health problems. However, most individuals neither agreed nor disagreed to live (48.5%), work (38%), and live nearby (42.7%) a mentally ill person, but maximum individuals strongly agreed to continue a relationship with a friend having mental health problems (34.5%). There were 77.5% males and 32.2% healthcare workers. Regarding intended behavior, there was a significant difference between healthcare workers and persons other than these as well as between males and females. Participants who had previous interaction with the mentally ill person were more willing to interact with the same.

Conclusion:

Most people do not intend to have stigmatized behavior toward mentally ill persons. Healthcare workers and males have less negative social reactions toward mentally ill persons in different domains of life. However, there is still a need to intensify awareness about mental health.
Absence of undergraduate medical students from psychiatric training
Authors: Mishra Kshirod Kumar , Rawekar Alka T. , Reshamvala Ahmed Mushtaq
Published: May 2021

Background:

Psychiatric problem is as common as among the 25% of the general population and 15% patients attending specialty clinic. Majority of the cases are dealt by primary care physician at the first contact, but there is only 2 weeks of clinical posting and 20 h of theory classes during MBBS course. Earlier studies have reported low attendance during the posting and theory classes. There are few studies on this aspect. On this background, the present study was planned.

Methodology:

One hundred 8th semester students of MBBS from two medical colleges (Group A government aided college and Group B from Private college under autonomous university) from the same locality of Central Maharashtra were selected for the study after due approval by the Institutional Ethical Committee. Questionnaire was prepared by the psychiatric faculty of both institutes and administered to the individual students. The data were analyzed using suitable statistical methods (Chi-square test and t-test).

Results:

Only 27% of the students in Group A attended 25%–30% of clinical posting, whereas none of them attended a single theory class. While in Group B, 1/3rd of students attended 30%–40% of clinical posting and 20%–25% of theory class. No separate examination in the subject (88%–94%) and adjustment of attendance in the other major subjects (64–86%) were cited as main reasons for nonattendance among the majority of the students in both the groups.

Conclusion:

Strict adherence to the attendance by the institutional authority, increase in the training hours and separate examination in the subject at undergraduate level may help in improving the attendance and change in attitude of the students toward psychiatry.

Authors: Saldanha Daniel , Mujawar Swaleha , Chaudhury Suprakash , Banerjee Amitav
Published: May 2021

Background:

Depression is a significant public health issue that needs to be taken care of, as it poses a great economic burden on the society at large. Early identification and treatment of the patients will reduce mental morbidity and disability.

Aim:

The aim is to study the prevalence and functional status of subjects with major depressive disorder in the community.

Materials and Methods:

After identification of the sample population, the sociodemographic details were recorded. Subsequently, assessment was carried out by General Health Questionnaire (GHQ), Patient Health Questionnaire-9 (PHQ-9), Functional Status Questionnaire (FSQ), and Mini Mental State examination (MMSE).

Results:

A total of 2000 subjects were screened using the GHQ and PHQ and 544 subjects were selected. These 544 subjects were further assessed with FSQ and MMSE. Out of the 544 subjects, 65.1% had a GHQ score of <14, 22.1% had a score between 15 and 19, and 12.9% had a score of >20. The PHQ-9 score was found to be <5 in 28.9% subjects, 5–14 in 64.3% subjects, and >14 in 6.8% subjects. Majority of the sample population was in the warning zone according to the FSQ. The MMSE scores were ≥23 in 86% and ≤22 in 14% of the patients. Over 65% of the subjects were relatively mentally healthy. Out of the remaining 35%, 22% of the subjects required screening for psychiatric disorders and 13% of them did require active psychiatric intervention.

Conclusions:

It would be beneficial to the community if a database is created regarding the psychiatric disorders such as depression prevalent in the community and their functional status so that the effective measures can be implemented to minimize the suffering by providing effective psychiatric care at the earliest and follow them up in the long run.

An ab initio study of small gas molecule adsorption on the edge of N-doped sawtooth penta-graphene nanoribbons
Authors: Nguyen Thanh Tien , Le Vo Phuong Thuan  , Tran Yen Mi
Published: May 2021

Adsorption of the toxic gas molecules carbon monoxide (CO), carbon dioxide (CO2) and ammonia (NH3 ) on the edge of N-doped sawtooth penta-graphene nanoribbons (N:SSPGNRs) was studied using first-principles methods. Basing our study on density functional theory (DFT), we investigated adsorption configurations, adsorption energy, charge transfer, and the electronic properties of CO-, CO2 - and NH3- adsorbed ontoN:SSPGNRs. We found that CO and CO2 are chemisorbed on the edge of N:SSPGNR, while NH3 is physisorbed. Current-voltage (I–V) characteristics were also investigated using the non-equilibrium Green’s function (NEGF) approach. Gas molecules can modify the current of a device based on N:SSPGNRs. The results indicate the potential of using N:SSPGNRs for detection of these toxic gas molecules.

Published: May 2021

La problématique actuelle en matière d’enseignement dans les pays d’Afrique subsaharienne en général et au Cameroun en particulier est centrée sur l’enseignement ou non en langues ou des langues locales. La politique linguistique camerounaise stipule que les deux langues officielles, le français et l’anglais, sont les langues d’enseignement. Les langues locales, quant à elles, doivent être promues en les introduisant dans les programmes d’enseignement à travers les cultures nationales. La promotion de ces langues doit être repensée en matière d’enseignement. Dans cet article, nous allons reconsidérer l’enseignement des langues locales. L’objectif ici sera de penser comment les introduire dans les différentes écoles de formation professionnelle, en l’occurrence le secteur de la santé. Ainsi, au terme de la formation, chaque apprenant·e pourra dialoguer, comprendre et se faire comprendre de ses patient·e·s; bref, il y aura donc un rapprochement certain, une sorte de confiance entre le soignant/la soignante et le ou la patient·e.

People are the main component as well as the target for social work practice. The intention of this profession is to help individuals /groups/communities to find out and solve their difficulties arising out of an imbalance between them and their surroundings and to assist them enhancing and restoring their capacities and potentials. On the other hand, Human Resource Management stands for recognizing and channelizing the uniqueness, talents, potentials, capabilities and strengths of human beings in work place, to develop their productivity as well as to ensure the protection of rights, social security, and justice for them. Human Resource Management is a term that aims to the blooming people as a valuable resource of the organization rather than their control as material assets. By analyzing the frameworks and philosophical bases of both the profession, it can be clearly elucidated that the practice of Human Resource Management, where it aims into resolve the disequilibrium in workplace relationship or employee-employer relationship and when it aims to identify, utilize and channelize all of their potentials and inner resources to develop their productivity the process of Social Work intervention strongly finds its way into the domain of practice of HRM and vis-à-vis.
Perception of the Farmers regarding Constraints Faced during Farmers’ Fair
Authors: Malik Anil Kumar
Published: May 2021

Famers’ fair an important tool in transferring latest technologies to farmers is gaining momentum over the years. The main purpose of organizing such farmers’ fair is to create awareness among visitors about new technologies developed by researchers primarily from the government sector, agricultural and allied research centres and State Agricultural Universities (SAUs). Considering its importance, an exploratory study was carried out to identify the constraints perceived by the visiting farmers and remedies suggested by them for improvement of farmers’ fair. The present study was conducted at Chaudhary Charan Singh Haryana Agricultural University (CCS HAU), Hisar main campus during 2019-20. Empirical data were collected through personal interview technique with the help of well-structured and pre-tested interview schedule and analyzed using standard methodology. Findings revealed that infrastructural constraints were perceived highest with composite index value (CIV) of 38.28, followed by physical (34.37), institutional (30.00), miscellaneous (19.27) and social (07.81) constraints. With regards to suggestions, most of the farmers suggested time duration of farmers’ fair should be increased followed by adequate transport facilities, seeds should be made available at low price, etc. Hence, the paper recommends that although the farmers’ fairs are playing an effective role in information dissemination but must be updated each year to catch more attention of the farmers.
A Numerically Efficient Technique for the Analysis of Metamaterial- and Metasurface-based Antennas
Authors: Nasri Abdelkhalek , Mittra Raj , Ghalib Asim , Hakim Bandar , Rmili Hatem
Published: May 2021

Metasurface-based antennas have received considerable recent attention in recent years because they are not only useful for designing new antennas, but for improving the performance of legacy designs as well. However, systematically designing these antennas is challenging because the antennas are usually multiscale in nature and they typically require a long time when simulated by using commercial solvers. In this work,
we present a new approach for analyzing antennas that utilize Metasurfaces (MTSs) and Metamaterial (MTMs). The proposed method departs from the widely used technique based on an anisotropic impedance representation of the surface and relies on an equivalent medium approach instead. The principal advantage of the proposed approach is that such an equivalent medium representation can be conveniently inserted directly in commercial EM solvers, circumventing the need to develop special numerical EM simulation codes to handle metasurfaces. Several illustrative examples
are presented in the paper to demonstrate the efficacy of the present approach when simulating MTS- and MTMbased antennas.
Dual-Band Bandpass Filter Optimized for High Q-Factor
Authors: Fahmy Walid , Farahat Asmaa , Hussein Khalid , Ammar Abd-El-Hadi
Published: May 2021

High quality factor bandpass filters based on a number of cascaded resonators of dual-resonance mechanism are proposed in the present paper. Each resonator is constructed as two overlapped coplanar waveguide (CPW) resonant structures. The cascaded resonators mediate microwave coupling between two isolated corner-shaped CPW feeders only at the resonant frequencies leading to a bandpass filter of high quality
factor. The two resonant frequencies and the separation between them can be fine-tuned by the dimensions of the structure. The effects of the dimensional parameters
of the resonator and the feeding CPW regions on the resonant frequencies and the performance of the bandpass filter are investigated. The effect of the loss tangent of the dielectric substrate material on the quality factors at the two resonant frequencies is studied. Three prototypes of the proposed filter are fabricated and experimentally studied for more understanding of the underlying physical principles of operation and for verifying some of the simulation results. The experimental results show good agreement when compared with the corresponding simulation results. It is shown that, at low enough absolute temperature, the proposed structure can operate as superconducting microwave resonator when made from the appropriate materials. Also, it is shown that an optimized design of the proposed bandpass filter, based on superconducting CPWR structure, can achieve quality factors high enough to form a quantum data bus for hybrid architecture of quantum information systems.
MIMO Antenna Based on Metamaterial Frequency Selective Surface
Authors: Luo Shengyuan , Li Yingsong , Sim Chow-Yen-Desmond , Xia Yinfeng , Liu Xiaoguang
Published: May 2021

In this paper, a metamaterial-based novel antenna-mutual-coupling reduction structure is proposed and demonstrated. The structure consists of a three-layer metamaterial frequency selective surface (MFSS) superstrate with split-ring resonators and metal grids. The MFSS means metamaterial frequency selective surface that has the metamaterial performance along the substrate and the frequency selective characteristic on the normal direction of the antenna array simultaneously. A 1×2 MIMO antenna that has a short edge-to-edge distance (0.037λ0) is designed as an illustration to demonstrate the validity of the meta-surface for mutual. When loaded with the proposed MFSS, the mutual coupling between the antenna elements is significantly reduced and the gain of the antenna array is improved by 2.5 dBi.

Bai ekonomia jasangarriari buruzko martxoaren 4ko 2/2011 Legeak eta
bai Zientzia, Teknologia eta Berrikuntzari buruzko ekainaren 1eko 14/2011 Legeak aldaketa

for those immaterial goods as their quality of assets.
LA LEGISLACIÓN AUTONÓMICA NO PUEDE ASIGNAR FUNCIONES ADMINISTRATIVAS AL PERSONAL EVENTUAL. COMENTARIO A LA STC 156/2013, DE 23 DE SEPTIEMBRE
Authors: OLIVÁN DEL CACHO JOSÉ JAVIER
Published: May 2021

El presente trabajo versa sobre la Sentencia del Tribunal Constitucional
156/2013, que declaró inconstitucional una previsión legislativa autonómica en la que se atribuían
a un empleado eventual (desde la perspectiva de su libre nombramiento y cese) funciones
materialmente administrativas. La inconstitucionalidad se basa en la contravención de la
prohibición contenida en la legislación básica estatal en relación con el ejercicio por el personal
eventual de funciones distintas de las de confianza o asesoramiento especial.

Lan hau Konstituzio Auzitegiaren 156/2013 Epaiari buruzkoa da, inkonstituzionaltzat
jo baitzuen erkidegoko lege-aurreikuspen bat non behin-behineko enplegatu

Izan ere, horrek urratu egiten du estatuko oinarrizko legeriaren debeku bat,
behin¿ behineko langileek konfiantza edo aholkularitza berezikoak ez diren zereginak egiteari
buruzkoa.

This work deals with the judgment 156/2013 of the Constitutional Court
that found inconstitutional an autonomic legislative provision that confered a temporary
public officer (from the point of view of his/her free appointment and dismissal) materially
administrative tasks. The inconstitutionality is based on the violation of the prohibition
established by the state basic legislation in relationship with the exercise of tasks by the
temporary staff different to those of trust and special advising.
LOS DERECHOS DE REALOJO Y RETORNO. ANTECEDENTES Y REGULACIÓN ESTATAL EN EL MODELO DE URBANISMO SOSTENIBLE
Authors: QUINTANA LÓPEZ TOMÁS
Published: May 2021

Los derechos de realojo y retorno, que cuentan con alguna tradición en
el ordenamiento jurídico español, han adquirido una nueva dimensión en el marco de la
renovada legislación de suelo que se pretende iniciar con la aprobación de la Ley 8/2007,
de 28 de mayo, de Suelo, de la que constituye un hito fundamental la más reciente Ley
8/2013, de 26 de junio, de Rehabilitación, Regeneración y Renovación Urbanas, ley ésta última
que contribuye a insertar el régimen de los mencionados derechos en un urbanismo
más atento a la conservación y renovación de la ciudad construida que a la expansión de la
misma y, con ella, a los fenómenos urbanizador y edificatorio, que tan arraigados han estado
en la legislación del suelo desde la primera ley urbanística española aprobada a mediados
del siglo pasado. Las actuales normas estatales reguladoras de los derechos de realojo
y retorno son objeto de atención en el presente estudio.

Rights to rehousing and return, which enjoy some tradition in Spanish
legal order, have assumed a new dimension within the updated legislation on land that
tries to begin with the enactment of Act 8/2007 of May 28th on Land, a crucial milestone
to the more recent Act 8/2013 of June 26th of Urban Restoration, Regeneration and
Renovation, act that contributes to include the regime of the aforementioned rights onto
a more focused urbanism on conservation and renovation of the built city than on its
extension itself, and with it, on the urban and constructing phenomena, which have been
so ingrained in the land legislation from the first spanish urban act enacted halfway the
past century. The current State provisions that regulate rights to rehousing and return are
object of attention by this study.
EL ACCESO A LA VIVIENDA Y LA NUEVA FUNCIÓN SOCIAL DEL DERECHO DE PROPIEDAD
Authors: TORNOS MAS JOAQUÍN
Published: May 2021

El grave problema del acceso a la vivienda en nuestro país ofrece además
la contradicción de contar con un abundante parque de viviendas desocupadas. Ante
esta situación algunos legisladores autonómicos han recurrido a un nuevo concepto de la
función social de la propiedad urbana, estableciendo como nueva obligación del propietario
el destinar la vivienda a su uso residencial, de modo que el destino de la propiedad urbana
queda fuera de la libre disposición del propietario. Para forzar el cumplimiento de esta
nueva función social se ha recurrido a medidas de carácter coactivo. Así, la expropiación
temporal del uso de las viviendas propiedad de entidades bancarias que hubieran accedido
a dicha propiedad como consecuencia de procesos hipotecarios, o la imposición de
sanciones o la exigencia de impuestos con fines no fiscales en los casos de mantener desocupadas
las viviendas. El trabajo analiza críticamente estas actuaciones, examinando su
validez jurídica y su eficacia.

Gure herrialdean arazo larria da etxebizitza eskuratzea, eta gainera etxebizitza
huts asko egotearen kontraesana dago. Horren aurrean, autonomietako legegile
batzuek hiri-jabetzaren gizarte-funtzioaren kontzeptu berrira jo dute, etxebizitza bertan bizitzeko
izatera behartuz, eta jabeak ez luke izango hiri-jabetzaren erabilera librerik. Gizartefuntzio
berri hori betearazteko, bortxazko neurriak hartu dira. Adibidez, hipoteka-prozesuen
ondorioz jabetza bat eskuratu duten banketxeen etxebizitzen erabilera aldi baterako desjabetzea,
edo zehapenak ezartzea edo helburu ez-fiskaleko zergak eskatzea etxebizitzak hutsik
daudenean. Lan honetan modu kritikoan aztertzen dira jarduera horiek, haien balio juridikoa
eta eraginkortasuna neurtuz.

The serious problem of access to housing in our country gives moreover
the contradiction of having a plentiful stock of empty houses. In the face of this situation
some autonomic legislators have resorted to a new concept of social function of urban
housing establishing a new propiertor¿s duty to set aside the house for residential use so
as to leave the destiny of the urban house out from the free use of the proprietor. In order
to force the fullfilment of this new social function measures of coactive nature have been
used. Hence, the interim expropriation of the use of houses owned by banking entities that
had acquired them as consequence of mortgage procedures or the imposition of penalties
or the request of levies with no tax purposes where the houses are unoccupied. This work
analyzes these interventions studying their legal validity and efficacy.
Moses Maimonides: leven en werk van een schitterend arts en filosoof
Authors: RUBENS R.
Published: May 2021

Moses Maimonides (1135 - 1204): life and work of a wonderful physician and philosopher

Moses ben Maimon or Maimonides was probably born in 1135 in Cordoba. Being the son of a rabbi and judge he received an excellent education, mainly in the school of Lucena. The permanent changes in the Islamic world in Andalusia and the persecutions of the Jews made him emigrate to Fez in Morocco.

At Al-Karaouine, one of the oldest universities of the world, he received a medical education by Avenzoar (1091-1161). Avenzoar was the first performer of tracheotomy and found the real origin of scabies. During his stay in Fez Maimonides also started his philosophical work. However, he again had to emigrate, this time he travelled to Acre. During a short stay there he visited Jerusalem in the Latin State.

Maimonides continued his peregrination to Fustat in Egypt. There he became the wise man in Jewry. He was even the physician of the powerful Saladin himself. During the same period he wrote important medical books, covering the whole of medicine and emphasising beneficence in medical ethics.

Maimonides died in 1204 and was buried in Tiberias, next to the Sea of Galilea as he requested.

His medical works are well preserved and give a careful insight in the medical knowledge of the medieval Islamic period. They contain an integration of the medical science of the Classical period into the Judeo-Arabic world.

Maimonides’ philosophical and rabbinical writings are universal and still studied today. His holistic vision and interest in the psychosomatic medicine make him a universal scientist.
COMPARISON OF MASSAGE THERAPY AND PASSIVE STRETCHING FOR REDUCING DOMS OF TIBIALIS ANTERIOR
Authors: Rehman Ateeb , Sadiq Noman , Khan Asghar
Published: May 2021

Purpose: To find the effect of massage therapy in comparison with static stretching for reducing DOMS in tibialis anterior muscle and to assess their effect on performance of athletes with these therapies.

Methodology: An experimental study was done in Imperial University Lahore for the duration of 06 months from 15 August to February 15. Participants were selected through non-probability convenience sampling technique as per inclusion criteria. Sample size was 40, from which participants were equally divided into two groups; Group-A (massage therapy) and Group-B (static stretching). DOMS were induced in tibialis anterior mucle and assessments was carried out before intervention and after applying intervention using NPRS, vertical jump height test, and sprint speed test.

Findings: Both massage therapy and passive static stretching techniques were found to be effective for reducing the muscle soreness in the tibialis anterior muscle, as well as for improving players’ performance. However, within group analysis shows that passive static stretching significantly improves the vertical jump height and sprint speed duration in the athletes.

Unique contribution to theory, practice and policy: The literature regarding the comparison of two techniques (massage & passive static stretching) is lacking especially their effect on tibialis anterior. This study fills the gap and will guide sports rehabilitators and trainers to devise better intervention strategies for countering the symptoms of DOMS and its effects on performance.
