Published: July 2021

Ang pag-aaral na ito ay may titulong “BALIDASYON AT PAGTANGGAP NG INTERAKTIBONG SUPPLEMENTAL NA MODYUL SA PERFORMANS NG MGA MAG-AARAL”. Layunin ng pag-aaral na ito na mabatid ang kabisaan ng supplemental na kagamitan bilang pantulong sa pagtuturo ng asignaturang Filipino sa mga mag-aaral ng ikapitong baitang sa Taong Panuruan 2020-2021.
Naisin din ng pag-aaral na ito na mabatid ang antas ng paggamit ng modyul bilang pantulong sa pagtuturo ng asignaturang Filipino batay sa nilalaman, kaugnayan, hikayat sa gagamit, pagkakaayos at kahalagahan; malaman ang antas ng pagkatuto ng mga mag-aaral sa asignaturang Filipino batay sa paunang pagsusulit at panapos na pagsusulit; malaman kung may makabuluhang pagkakaiba ang antas ng pagkatuto ng mga mag-aaral batay sa pauna at panapos na pagsusulit; at mabatid kung mayroon bang makabuluhang relasyon ang paggamit ng modyul bilang supplemental na kagamitan sa pagtuturo ng asignaturang Filipino sa pagkatuto ng mga mag-aaral.
Ang pananaliksik na ito ay isinagawa upang makabuo ng kagamitang panturo sa ikaapat na markahan ng asignaturang Filipino bilang kagamitan na makatutulong sa pagpapaunlad sa proseso ng pagtuturo ng guro at pagkatuto ng mag-aaral. Nilayon ng pag-aaral na malaman ang lebel ng pagtanggap ng guro at mag-aaral sa modyul. Ito ay isang kwantitatibong pag-aaral at gumamit ng deskriptibong pananaliksik na ginamitan ng talatanungan sa anyong mga tanong at checklist. Ginamit sa pananaliksik na ito ang purposive sampling sa pagpili ng mga tagasagot mula sa mag-aaral at guro para sa pagtanggap ng materyal mula sa Lucban Academy. Ang weighted mean ay ginamit ng mananaliksik bilang pamamaraang estadistika upang matukoy ang lebel ng pagtanggap sa binuong modyul bilang supplemental na kagamitan. Batay sa kinalabasan ng pananaliksik, ang modyul ay lubos na katanggap-tanggap batay sa nilalaman, kaugnayan, hikayat sa gagamit, pagkakaayos at kahalagahan. Ang mga mag-aaral na nakagamit ng binuong supplemental na modyul ay nadagdagan ang kaalaman pagdating sa paksa, mas naipaliwanag nila ang saloobin hingil sa inaaral na mga aralin at naging makabuluhan ang kasagutan na may tumpak na sagot. Sa pagtanggap ng mga guro sa modyul at pagpapagamit sa mga mag-aaral, mas tumaas ang performans ng mga mag-aaral at naging interaktibo ang mga aralin sa ikaapat na markahan sa Filipino. Lubos na mas magiging malawak ang pagkatuto ng mga mag-aaral kung ang modyul na binuo ay ipapagamit pa sa susunod na markahan o baitang.
Nangangahulungan lamang na ang kagamitang modyul ay isang mabisang kagamitang panturo na maaring magamit sa pagtalakay ng mga aralin. Nabuo ang mungkahi na sa susunod na pananaliksik ay ipagamit sa guro at mag-aaral ang modyul upang maging gabay sa aralin at maaari pang bumuo ng modyul o iba pang supplemental na kagamitan para sa ibang baitang o ibang markahan na maaaring gamitin sa pagtuturo at pagkatuto upang maging interaktibo ang talakayan

Authors: Lapin Vladimir A. , Aldakhov Yerkin S. , Aldakhov Serik D. , Alimzhan Ali
Published: July 2021

Under the agreement with the city authorities, in 2017-2018, for the first time, a

full certification of the housing stock of apartment buildings was carried out. 2658 multi-storey

large-panel buildings of various storeys from 2 to 9 floors were entered into the database. Based on

the results of certification, quantitative estimates of the probability of failure and reliability for

large-panel buildings of various types were obtained for the first time. The frequency of

earthquakes is taken into account according to the current "Map of seismic zoning of the Republic

of Kazakhstan". The reliability value is obtained for the entire group of large-panel buildings. It

was revealed that large-panel buildings with the first flexible or brick floor are not earthquakeresistant.

The results of the reliability and failure estimates are used for practical recommendations

to reduce the risk and expected losses in possible earthquakes. It is proposed to strengthen largepanel

buildings with the first flexible or brick floor (33 buildings). The method of strengthening

should be determined by special studies.
The antiresonance phenomena in seismic microzonation
Authors: Aleshin Alexander S.
Published: July 2021

The interference of incident and reflected seismic waves in the ground massif near

the day surface is the cause of resonant effects. In the practice of seismic microzonation (SMZ),

a resonant increase in the total seismic intensity is of particular importance. At the same time, the

presence of inverse layers in the ground layers interference leads to a decrease in the intensity of

the total seismic impact, what is naturally named antiresonance. The article considers the

conditions for the occurrence of antiresonance and evaluates the limits of its effectiveness. The

natural and man-made causes of antiresonance and the possibility of using it to reduce the

intensity of seismic impacts are particularly noted.

The problem of the High Social Gap in Papua which is the cause of marginalization and discrimination against the Papuan people, as well as the different perceptions of some Indonesians at home and abroad towards armed separatist conflicts are push factors to corner the Indonesian government. In addition, the issue of internationalization of the 1969 referendum mechanism, violations of Human Rights (HAM), and the management of Natural Resources (SDA) by multinational companies that do not have an impact on improving the welfare of the Papuan people also complement the government's opinion of failure. Against the background of these problems, this study uses a quasi-qualitative research method and an exploratory approach with soft systems methodology (SSM) as a data analysis technique to answer the formulation of the problem and research questions. Research data were collected through Focus Group Discussions (FGD), in-depth interviews, and direct discussions with various informants (academics, practitioners, bureaucracy, and community leaders), plus a literature review as secondary data. The results of this study recommend the development of an Integrated Food Estate (IFE) in stages according to customary areas in Papua, which will indirectly support the realization of Territorial Resilience and the Universal Defense System (Sishta). Furthermore, to ensure that all these processes are carried out properly and continuously, this study recommends the establishment of an Integrated Solution Center (ISC). With the implementation of these recommendations, it is hoped that the peaceful and prosperous Papuan people will soon be realized.

Published: July 2021

Vincentius Kristus Raja (KR) Main Clinic aims to serve patients effectively and economically in an effort to improve the quality of public health services, especially in Surabaya. This type of research is descriptive qualitative in the form of a case study, to assess the implementation of standard operating procedures at the Vincentius Kristus Raja Main Clinic. Relevant data collection was carried out using questionnaires distributed to personnel related to standard operating procedures. The results of the research study according to the questionnaire indicate that the operational implementation is in accordance with the standard operating procedures that have been set based on the policies of the leadership and the Vincentius Kristus Raja Main Clinic Foundation. Compliance with standard operating procedures is very important because standard operating procedures are guidelines or references for carrying out tasks and work in accordance with their functions. The conclusions and suggestions from this study are that although compliance with standard operating procedures is adequate, the Vincentius Kristus Raja Main Clinic needs to develop and improve the quality of services, especially better communication with patients, both new patients and patients who have been on treatment for a long time at the Vincentius Kristus Raja Main Clinic. Considering that there are now many new health clinics that can be competitors for the Vincentius Kristus Raja Main Clinic, there must be a good response to this phenomenon. The emergence of these new competitors requires the Vincentius Kristus Raja Main Clinic to be able to be competitive in order to face the existing competition by improving the quality and quality of service for patients.

Published: July 2021

Решается задача одномерной плоской деформации нелинейноупругого несжимаемого полупространства под действием ударной нагрузки на его границе. До момента ударного воздействия полупространство находится в свободном состоянии. Именно это условие позволяет осуществить движение разрыва в краевых условиях на границе полупространства в виде единственной плоскополяризованной ударной волны, на которой сохраняется неизменным направление предварительного сдвига. Перечисленные свойства переднего фронта ударного воздействия следуют из совместного анализа характеристических направлений задачи и видов ударных волн для одномерной плоской задачи в несжимаемой среде с произвольными предварительными деформациями. Приводятся два варианта приближенного решения задачи на основе метода сращиваемых асимптотических разложений и на основе метода лучевых рядов.

The problem of one-dimensional plane deformation of a nonlinear elastic incompressible half-space under the impact load action on its boundary is solved. The half-space is in a free state until the moment of impact action. This condition leads to the discontinuity in the boundary conditions at the half-space boundary moves as the only plane-polarized shock wave, on which the direction of the preliminary shear remains unchanged. The pointed out properties of the leading edge of the shock action follow from the joint analysis of the characteristic directions of the problem and the shock waves types for a one-dimensional plane problem in an incompressible medium with arbitrary preliminary deformations. Two versions of the problem approximate solution based on the method of matched asymptotic expansions and on the basis of the ray series method are presented.

Published: July 2021

In the article the results of field and laboratory researches of gully erosion in the mountains of Zhetysu Alatau of south-east Kazakhstan are considered. Mountain ridge Malaisary was chosen for study of gully erosion. Malaisary ridge is the western ridge of Zhetysu Alatau mountains in the south-east Kazakhstan. Foothills and plain territories of southeast Kazakhstan are characterized by favorable conditions for the development of erosion processes. There was conducted stationary monitoring (yearly in October from 2013 to 2018) of gully erosion development on the Malaisary ridge from 2013 to 2018. Most of gullies of studied ridge show development in the top part and extend in the width mainly due to fluvial processes. There were studied the natural-anthropogenic factors influencing development of gully erosion; the morphometric characteristic received using the modern devices and satellite images are provided. The determined factors of development of gullies on Malaisary ridge are mechanical substratum composition, atmospheric precipitation (spring runoff, summer rainfalls), steepness and length of the slopes. The received materials allow concluding that gully erosion is the most active factor of the ridge relief transformation. Intensive gully erosion development increases ecological tension of natural-anthropogenic environment in the region. Growth of gully net and its active development deteriorates quality of agricultural lands and create threat to road objects and residential area infrastructure in the region.
REAL OPTION AND VERTICAL MIXED-USE DEVELOPMENT
Authors: Zhong Jiawei , Hui Eddie C. M.
Published: July 2021

Vertical mixed-use development is a favourite choice in urban development in high-density Asian cities to increase the land use efficiency. The flexibility of construction timing and the restrictions by lease contracts in vertical mixeduse projects are usually different from horizontal ones and single-use properties. To improve the valuation for vertical mixed-use projects, this study re-examines the real option pricing model. Simultaneous development for different uses and a finite maximum waiting period are the major characteristics of these projects. An approach is introduced to determine whether to develop a mixed-use project vertically or horizontally on the basis of a statistics called the critical height premium. The vertical mixed-use project pricing model can be further verified by containing a height premium if market price information is derived from non-vertical mixed-use properties. This study suggests a more comprehensive real option approach to quantify the advantages and disadvantages of operating vertical mixed-use developments.

In Dou et al., we introduced the fundamental formation relation (FFR), a tight relation between specific star formation rate (sSFR), H2 star formation efficiency (SFE

H

2

), and the ratio of H2 to stellar mass. Here, we show that atomic gas H ɪ does not follow a similar FFR as H2. The relation between SFEHɪ and sSFR shows significant scatter and strong systematic dependence on all of the key galaxy properties that we have explored. The dramatic difference between H ɪ and H2 indicates that different processes (e.g., quenching by different mechanisms) may have very different effects on H ɪ in different galaxies and hence produce different SFEHɪ–sSFR relations, while the SFE

H

2

–sSFR relation remains unaffected. The fact that the SFE

H

2

–sSFR relation is independent of other key galaxy properties, and that sSFR is directly related to the cosmic time and acts as the cosmic clock, make it natural and very simple to study how different galaxy populations (with different properties and undergoing different processes) evolve on the same SFE

. This simplicity allows us to accurately derive the H2 supply and removal rates of the local galaxy populations with different stellar masses, from star-forming galaxies to the galaxies in the process of being quenched. This combination of FFR and GRM, together with the stellar metallicity requirement, provide a new powerful tool to study galaxy formation and evolution.

The [C ii] fine-structure transition at 158 μm is frequently the brightest far-infrared line in galaxies. Due to its low ionization potential, C+ can trace the ionized, atomic, and molecular phases of the ISM. We present velocity-resolved [C ii] and [N ii] pointed observations from SOFIA/GREAT on ∼500 pc scales in the nearby galaxies M101 and NGC 6946 and investigate the multiphase origin of [C ii] emission over a range of environments. We show that ionized gas makes a negligible contribution to the [C ii] emission in these positions using [N ii] observations. We spectrally decompose the [C ii] emission into components associated with the molecular and atomic phases using existing CO (2–1) and H i data and show that a peak signal-to-noise ratio of 10–15 is necessary for a reliable decomposition. In general, we find that in our pointings ≳50% of the [C ii] emission arises from the atomic phase, with no strong dependence on star formation rate, metallicity, or galactocentric radius. We do find a difference between pointings in these two galaxies, where locations in NGC 6946 tend to have larger fractions of [C ii] emission associated with the molecular phase than in M101. We also find a weak but consistent trend for fainter [C ii] emission to exhibit a larger contribution from the atomic medium. We compute the thermal pressure of the cold neutral medium through the [C ii] cooling function and find

Orbital Migration and Circularization of Tidal Debris by Alfvén-wave Drag: Circumstellar Debris and Pollution around White Dwarfs
Authors: Zhang 张 Yun 韵 , Liu 刘 Shang-Fei 尚飞 , Lin 林 Douglas N. C. 潮
Published: July 2021

A significant fraction of white dwarfs (WDs) exhibit signs of ongoing accretion of refractory elements at rates ∼103–107 kg s−1, among which, 37 WDs were detected to harbor dusty debris disks. Such a concurrence requires not only fertile reservoirs of planetary material but also a high duty cycle of metal delivery. It has been commonly suggested that this material could be supplied by solar system analogs of Main Belt asteroids or Kuiper Belt objects. Here we consider the primary progenitors of WD pollutants as a population of residual high-eccentricity planetesimals, devolatilized during the stellar giant phases. Equivalent to the solar system’s long-period comets, they are scattered to the proximity of WDs by perturbations from remaining planets, Galactic tides, passing molecular clouds, and nearby stars. These objects undergo downsizing when they venture within the tidal disruption limit. We show quantitatively how the breakup condition and fragment sizes are determined by material strength and gravity. Thereafter, the fragments’ semimajor axes need to decay by at least ∼6 orders of magnitude before their constituents are eventually accreted onto the surface of WDs. We investigate the orbital evolution of these fragments around WDs and show that WDs’ magnetic fields induce an Alfvén-wave drag during their periastron passages and rapidly circularize their orbits. This process could be responsible for the observed accretion rates of heavy elements and the generation of circum-WD debris disks. Speculative implications are that giant planets may be common around WDs’ progenitors and that they may still be bound to some WDs today.
Photoevaporation of Grain-depleted Protoplanetary Disks around Intermediate-mass Stars: Investigating the Possibility of Gas-rich Debris Disks as Protoplanetary Remnants
Authors: Nakatani Riouhei , Kobayashi Hiroshi , Kuiper Rolf , Nomura Hideko , Aikawa Yuri
Published: July 2021

Debris disks are classically considered to be gas-less systems, but recent (sub)millimeter observations have detected tens of those with rich gas content. The origin of the gas component remains unclear, but it could be protoplanetary remnants and/or secondary products from large bodies. In order to be protoplanetary in origin, the gas component of the parental protoplanetary disk is required to survive for

lifetimes because of efficient photoevaporation at the late stage of disk evolution. We investigate photoevaporation of gas-rich, optically-thin disks around intermediate-mass stars at a late stage of the disk evolution. The evolved system is modeled like those devoid of small grains (

and depend on the “initial” disk mass at the point small grains have been depleted in the system. We show that the gas component can survive for a much longer time around A-type stars than lower-mass (F-, G-, K-type) stars owing to their atypical low EUV (and X-ray) luminosities. This trend is consistent with the higher frequency of gas-rich debris disks around A-type stars, implying the possibility of the gas component being protoplanetary remnants.
Southward range extension of the goldeye rockfish, Sebastes thompsoni (Actinopterygii: Scorpaeniformes: Scorpaenidae), to northern Taiwan

The goldeye rockfish,Sebastes thompsoni(Jordan et Hubbs, 1925), is known as a typical cold-water species, occurring from southern Hokkaido to Kagoshima. In the presently reported study, a specimen was collected from the local fishery catch off Keelung, northern Taiwan, which represents the first specimen-based record of the genus in Taiwan. Moreover, the new record ofSebastes thompsoniin Taiwan represented the southernmost distribution of the cold-water genusSebastesin the Northern Hemisphere.
À l’origine des milices de couleur : mobilité sociale et ségrégation dans les villes de l’empire espagnol
Authors: Bonnefoy Baptiste
Published: July 2021

Dès la fin du xvi e  siècle, les villes coloniales espagnoles étaient structurées par deux rapports hiérarchiques : le premier opposait les hommes libres aux esclaves et le second distinguait les Blancs des gens de couleur. Malgré cette centralité de la couleur, la séparation entre des milices de Blancs et des milices de couleur ne fut jamais automatique ou évidente. Cet article vise à restituer la genèse des compagnies de couleur de l’Amérique espagnole afin de mettre en rapport deux dynamiques qui émergent au tournant des xvi e et xvii e  siècles : la formation d’élites de couleur et le rôle croissant des lexiques de la couleur dans les manières de dire les hiérarchies sociales.
Analyse phénoménologique interprétative du vécu expérientiel des étudiantes au baccalauréat en sciences infirmières lors d’un stage en santé mentale. Comprendre pour mieux former
Authors: Bujold Audrey , Pariseau-Legault Pierre , de Montigny Francine
Published: July 2021

Dans un contexte mondial où les besoins populationnels en santé mentale sont en forte croissance, le recrutement de la relève infirmière dans ces milieux de soins est particulièrement problématique. En raison de leurs perspectives négatives des enjeux liés à la santé mentale, les étudiantes en soins infirmiers rejettent un tel cheminement de carrière. Selon les écrits, les programmes de formation, notamment les immersions cliniques, constituent le principal levier pour atténuer ce phénomène d’impopularité de la santé mentale auprès de cette relève. À travers une analyse phénoménologique interprétative des entretiens semi-dirigés de 11 étudiantes au baccalauréat en sciences infirmières, cette recherche a étudié leur expérience d’apprentissage lors d’une immersion clinique en santé mentale. Enracinée à la théorie de l’humain en devenir, cette étude explore le sens que les étudiantes attribuent à une telle expérience, les processus de négociation expérientielle du milieu de stage, ainsi que la capacité des participantes à se projeter au-delà de l’expérience d’apprentissage. Ces résultats soulèvent ainsi différents enjeux liés à la formation infirmière en santé mentale, notamment l’importance d’un modèle de rôle infirmier, ainsi que divers facteurs d’influence liés au rejet d’une carrière en santé mentale par la relève comme la perception d’un risque exacerbé d’agression.
Intégration des infirmières praticiennes en soins de santé primaires : repenser la négociation de dynamiques complexes
Authors: Rioux-Dubois Annie , Perron Amélie
Published: July 2021

L’intégration des infirmières praticiennes en soins de santé primaires est hautement complexe mais peu étudiée au regard de changements socioprofessionnels plus larges dans le système de santé. Objectif : le but de cette étude était d’examiner l’intégration et la négociation du rôle des infirmières praticiennes en contexte interprofessionnel dans divers modèles de soins de santé primaires. Méthode : une ethnographie multisite critique, combinant la théorie de l’acteur-réseau et les concepts foucaldiens de discours et pouvoir, a été menée au sein de trois différents modèles de soins dans lesquels des entrevues semi-dirigées (n=23 infirmières praticiennes), de l’observation directe et de l’analyse documentaire ont été réalisées. Résultats : les finalités organisationnelles, les normes de pratique, le droit des infirmières praticiennes à l’autodétermination, les dynamiques de collaboration avec les médecins, ainsi que la prise en charge des patients ont été identifiés comme des facteurs d’intégration produisant davantage d’instabilités, de négociations et de contrecoups professionnels, identitaires et moraux chez ces professionnelles. Discussion : ces résultats remettent en question la perception répandue d’un manque de clarté du rôle des infirmières praticiennes et permettent une compréhension renouvelée de leur intégration en soins de santé primaires.

Authors: Bernard Laurence , Bévillard-Charrière Quentin , Taha Samy , Holmes Dave
Published: July 2021

Contexte : le contexte actuel lié à la COVID-19 place les infirmières au cœur de la pandémie car elles assurent un rôle essentiel auprès de la population. Toutefois, les discours médiatiques et professionnels influencent l’identité et la pratique clinique des infirmières. Objectif : recenser et analyser les écrits traitant de la construction d’une identité populaire de l’infirmière et de ses rôles en temps de pandémie liée à la COVID-19. Méthode : les sources de données Eurêka, Google News, Education Resources Information Center (ERIC), Sociological Abstracts, Cumulative Index to Nursing Information and Allied Health Literature (CINAHL), MEDLINE et Social Sciences Abstracts ont été consultées. Des recherches manuelles sur les sites gouvernementaux et professionnels ont été ajoutées. Résultats : sur un total de 281 écrits répertoriés, 73 ont été retenus. L’analyse des écrits a permis de dégager les thèmes suivants : les images identitaires des infirmières durant cette pandémie et leurs rôles professionnels. Les discours autant médiatiques que politiques sont parfois paradoxaux. Ces derniers semblent influencer la pratique clinique infirmière qui se voit attribuer de nouveaux rôles. Conclusion : cet article permet de sensibiliser les décideurs aux rôles multiples des infirmières et à l’image qu’a le public de ces dernières en temps de pandémie, et de porter un regard critique sur les discours populaires en lien avec l’identité infirmière et sa modulation en temps de pandémie.
