Published: April 2021

Like we know gender construction is always connected to cultural, and when the culture change it will effect gender construction. Yogyakarta lika other country in Indonesia,have high experience in modernisasi. This process will effect to culture in small or big part.  This paper is a discription and explanation about gender construction in Yogyakarta on this era, written based on research. This research was conducted by necessity to know about the changes gender construction in  community that have modernisation process. This process can  create new relation between man and woman in many aspect. As a city that have strong patriarkhie culture, Yogyakarta can not avoid the modernisation process. And this process can influence that patriakhie culture, and than influence gender ralation indirectly in Yogyakarta. Gender construction in this paper is seen from four aspects, those are education, economi,  politic dan double garden.  Modernisation give effects on same aspek of gender construction. Although same aspect specially in public domain there is same changes in gender construction like in education, economi dan politic, but in domestic area specially doble garden, we can see that we find remains thd same. So we still can see the gender bias in domestic area. This research doing with discriptif method.

Islâhat Çağında Osmanlı Halkının Dinî Hayatını “Islâh”a Yönelik Saçaklızâde’nin İlginç Bir Önerisi: “ ʻİlim ve ʻAmele Da’vet ve İcbâr”
Authors: Gel Mehmet
Published: April 2021

Bu çalışmada 17. ve 18. yüzyıllarda yaşamış bir Osmanlı taşra âlimi olan Saçaklızâde Muhammed el-Mar'aşî (ö.1732)'nin Mektûb ilâ ulemâi'l-bilâd ve Nasîhatü'l-ulemâ başlıklı iki risâlesindeki fi kirleri incelenmektedir. Saçaklızâde bu risâlelerinde yaşadığı dönemde Osmanlı toplumunda dinin geri plana itildiği, ulemâ ve ümerânın halkı din işlerine "da'vet" ve "icbâr" etme konusunda yeterince gayret göstermedikleri gibi dikkat çekici iddialar dile getirmektedir. Ayrıca o, bu risâlelerinde daha dikkat çekici bir husus olarak o dönemde ulemânın şeri'atı canlandırma (ihyâ), dini yenileme (tecdîd) ve müslüman halkın din işlerini düzeltme (ıslâh) lüzumunun doğduğunu öne sürmektedir. Şüphesiz ki bu fi kirler gerek bir âlim olarak onun ilmî zihniyeti, gerekse Osmanlı dinî-sosyal tarihi bağlamında çok önemli veri niteliğinde olup tahlil edilmeyi fazlasıyla hak etmektedir.

Diplomasi tarihinin en elim vakıalarından biri 11 Şubat 1829 tarihinde Tahran'da meydana gelmiştir. Rusya ve İran (Kaçar) devletleri arasında iki yıl süren savaşın ardından imzalanan Türkmençay Antlaşması, iki ülke arasında diplomatik misyonların oluşturulmasını gündeme getirmekle birlikte, antlaşma maddelerinin uygulanması konusunda ortaya çıkabilecek sıkıntıların büyükelçilik nezdinde çözüme kavuşturulmasını da öngörmekteydi. Ancak savaşın geride bıraktığı husumetler, ilk kez böyle bir görev ifa eden Rus Büyükelçi Griboedov'un hataları, bölgede söz sahibi olmak isteyen diğer aktörler, dini fanatizm boyutunda yaşayan halkın inancını istismar eden provokatörler ve birtakım talihsizlikler bir araya gelince, iki ülke diplomasisi adına eşine benzerine rastlanılamayacak derecede büyük bir trajedi ortaya çıktı. Rus Büyükelçilik delegasyonunun neredeyse tamamının katledildiği 11 Şubat'taki baskının ardından kopması beklenen fırtına ise Rusya'nın içinde bulunduğu siyasi konjonktür sebebiyle akim kalmıştır. Bu çalışmada, dönemin ana kaynakları ışığında 11 Şubat 1829 tarihli Rus Büyükelçiliği baskını mercek altına alınacak, nedenleri ve sonuçları üzerinde bir takım tespitlerde bulunulacaktır.
The Lloyd George Government of the UK: Balfour Declaration the Promise for a National Home to Jews (1916-1920)
Authors: Köse İsmail
Published: April 2021

Palestine, throughout modern known history has been geographically called "the least of all lands". Meanwhile because hosted holy shrines of three monotheistic religions, it was/is one of the most praised/precious small piece of land on the globe. Palestine came under Ottoman rule after Sultan Selim's Egyptian Campaign in 1517 and until the year of 1917 was an Ottoman land during 400 years. Before Ottomans, following old Roman experience, small colonies or administrations had been planted in Palestine with the express intention of preventing the political regeneration of the Jews. Under Ottoman rule, Jews and other two religions have been peacefully living in Palestine. In 1897 at Basel Congress, World Zionist Organization decided to establish a Jewish State in Palestine. They asked Ottoman Sultan Abdulhamid II for a national home in Palestine but could not achieve what they desired. Abdulhamid II also restricted Jewish pilgrimage to Palestine to prevent any possible de facto unpermitted foreign settlement of Jews. But, due to corruption and bribery of local rulers that rule could not be implemented properly. Nowadays addressing their future plans Zionists were asking to send high number of Jews to Palestine and the progress taken by bribery was not enough such kind of stream. The opportunity Zionists looking for emerged during WWI while British search of support for unsustainable war economy. In the year of 1916, a Zionist sympathizer Lloyd George became British Prime Minister and Foreign Minister of his Cabinet Arthur Balfour proclaimed his famous publication promising a national home hence Israeli State for Jews. To realize that aim Palestine had to be occupied and become a British colony. This paper will search archive documents and related second hand publications to shed light on Zionist activities and establishment process of Israel, special focus will be put on the role of Lloyd George Government. Arab reactions, especially the attitude of Sheriff Hussein and his son Faisal to the developments also will be discussed.
Osmanlı Hükümetinin Kosova Arnavutları Arasındaki Kan Davalarına Çözüm Bulma Çabaları 1908-1912
Authors: Özbozdağlı Özer
Published: April 2021

Arnavutlar arasında kan davaları geleneksel yapanın hakim olduğu Kosova vilayetinin kuzey bölgelerinde yaygın bir toplumsal gerçeklikti. Kan davaları gelenek ve ananenin bir sentezi olan Lek Dukakin kanunundan beslenmekteydi. Kan davaları 19. yüzyıla gelindiğinde Osmanlı modernleşmesi ve merkezîleşmesiyle çatışan bir olgu haline geldi. Osmanlı devleti kan davalarını çözmek için yerel gelenek ve kanunlarla eklemlenebilen esnek bir politika geliştirdi. Bu bağlamda Arnavutların yaşadığı hudut bölgelerinde kamu düzenini bozan kan davalarını çözmek için II. Abdülhamit döneminde Musalaha-i Dem Komisyonları kuruldu. Komisyonların kan davalarını çözme de başarı sağlaması üzerine komisyonlar 1908 Temmuzunda Meşrutiyetin yeniden ilanından sonra tekrar kuruldu. İttihatçılar Makedonya hinterlandındaki hudut boylarının güvenliği sağlamak kapsamlı bir entegrasyon politikasını uygulamaya koydu. Bu siyasetin başarılı olabilmesi için Arnavut bölgelerinde kamu düzeni ve asayişi tehdit eden kan davalarının çözülmesi gerekliydi. İttihatçılar sorunu II. Abdülhamit döneminde tecrübe edilen Musalaha-i Dem Komisyonlarını tekrar kurarak çözmeye çalıştı. Komisyonların kaldırılmasından sonra ceza hukuku ve mahkemeler devreye sokuldu. Ancak geleneksel yapının güçlü olduğu Arnavut bölgelerinde kan davalarının artarak devam etmesi sebebiyle Musalaha-i Dem Komisyonları 1910,1911 ve 1912 Arnavut isyanlarından sonra tekrar kuruldu. Bu çalışmada Meşrutiyetin yeniden ilanından sonra Osmanlı devletinin Kosova Arnavutları arasındaki kan davalarını çözme çabaları ve Musalaha-i Dem Komisyonlarının faaliyetleri arşiv belgeleri ışığında değerlendirilmiştir.
An Update on Contraception in Polycystic Ovary Syndrome
Authors: Oguz Seda Hanife , Yildiz Bulent Okan
Published: April 2021

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology. Combined oral contraceptives (COCs), along with lifestyle modifications, represent the first-line medical treatment for the long-term management of PCOS. Containing low doses of estrogen and different types of progestin, COCs restore menstrual cyclicity, improve hyperandrogenism, and provide additional benefits such as reducing the risk of endometrial cancer. However, potential cardiometabolic risk associated with these agents has been a concern. COCs increase the risk of venous thromboembolism (VTE), related both to the dose of estrogen and the type of progestin involved. Arterial thrombotic events related to COC use occur much less frequently, and usually not a concern for young patients. All patients diagnosed with PCOS should be carefully evaluated for cardiometabolic risk factors at baseline, before initiating a COC. Age, smoking, obesity, glucose intolerance or diabetes, hypertension, dyslipidemia, thrombophilia, and family history of VTE should be recorded. Patients should be re-assessed at consecutive visits, more closely if any baseline cardiometabolic risk factor is present. Individual risk assessment is the key in order to avoid unfavorable outcomes related to COC use in women with PCOS.

Intermittency of Fast MHD Modes and Regions of Anomalous Gradient Orientation in Low-β Plasmas
Authors: Ho Ka Wai , Lazarian A.
Published: April 2021

The strong alignment of small-scale turbulent Alfvénic motions with the direction of magnetic field that percolates the small-scale eddies and imprints the direction of the magnetic field is a property that follows from the MHD theory and the theory of turbulent reconnection. The Alfvénic eddies mix magnetic fields perpendicular to the direction of the local magnetic field, and this type of motion is used to trace magnetic fields with the velocity gradient technique (VGT). The other type of turbulent motion, fast modes, induces anisotropies orthogonal to Alfvénic eddies and interferes with the tracing of the magnetic field with the VGT. We report a new effect, i.e., in a magnetically dominated low-β subsonic medium, fast modes are very intermittent, and in a volume with a small filling factor the fast modes dominate other turbulent motions. We identify these localized regions as the cause of the occasional change of direction of gradients in our synthetic observations. We show that the new technique of measuring the gradients of gradient amplitudes suppresses the contribution from the fast-mode-dominated regions, improving the magnetic field tracing. In addition, we show that the distortion of the gradient measurements by fast modes is also applicable to the synchrotron intensity gradients, but the effect is reduced compared to the VGT.
The Distribution and Evolution of Quasar Proximity Zone Sizes
Authors: Chen Huanqing , Gnedin Nickolay Y.
Published: April 2021

In this paper, we study the sizes of quasar proximity zones with synthetic quasar absorption spectra obtained by postprocessing a Cosmic Reionization On Computers (CROC) simulation. CROC simulations have both relatively large box sizes and high spatial resolution, allowing us to resolve Lyman limit systems (LLSs), which are crucial for modeling the quasar absorption spectra. We find that before reionization, most quasar proximity zone sizes grow steadily for ∼10 Myr, while after reionization, they grow rapidly but only for ∼0.1 Myr. We also find a slow growth of R
obs with decreasing turn-on redshift. In addition, we find that ∼1%–2% of old quasars (30 Myr old) display extremely small proximity zone sizes (<1 proper Mpc), the vast majority of which are due to the occurrence of a damped Lyα absorber (DLA) or an LLS along the line of sight. These DLAs and LLSs are contaminated with metal, which offers a way to distinguish them from the normal proximity zones of young quasars.
Growth of Massive Disks and Early Disk Fragmentation in Primordial Star Formation
Authors: Kimura Kazutaka , Hosokawa Takashi , Sugimura Kazuyuki
Published: April 2021

Recent high-resolution simulations demonstrate that disks around primordial protostars easily fragment in the accretion phase before protostars accrete less than a solar mass. To understand why gravitational instability generally causes fragmentation so early, we develop a one-dimensional (1D) nonsteady model of the circumstellar disk that takes the mass supply from an accretion envelope into account. We also compare the model results to a three-dimensional (3D) numerical simulation performed with a code employing adaptive mesh refinement. Our model shows that the self-gravitating disk, through which the Toomre Q parameter is nearly constant at Q ∼ 1, gradually spreads as the disk is fed by the gas infalling from the envelope. We further find that the accretion rate onto the star is an order of magnitude smaller than the mass supply rate onto the disk. This discrepancy makes the disk more massive than the protostar in an early evolutionary stage. Most of the infalling gas is used to extend the outer part of the self-gravitating disk rather than transferred inward toward the star through the disk. We find that similar evolution also occurs in 3D simulations, where the disk becomes three times more massive than the star before the first fragmentation occurs. Our 1D disk model well explains the evolution of the disk-to-star mass ratio observed in the simulation. We argue that the formation of such a massive disk leads to early disk fragmentation.
Magnetorotational Instability in Quantum Dusty Plasma
Authors: Usman S. , Mushtaq A.
Published: April 2021

Magnetorotational instability (MRI) in complex quantum plasma, which comprises electron, ion, and dust grains, is investigated. Electrons are considered to be degenerate while ions and dust grains are taken as nondegenerate. The general dispersion relation for MRI with the effect of spin magnetization is derived using local approximations. The instability criteria for spin quantum plasma are derived using low-frequency approximations. Due to the complex nature of the dispersion relation, MHD assumptions are used to define the instability criteria. The dust mass plays a significant role in both the dispersion and growth rate of the magnetorotational mode. The complex mass of dust modifies the instability criteria. Spin magnetization force arises due to electron Pauli spin matrices and has an important role in low-temperature and highly dense plasmas that are found mainly in white dwarfs, neutron stars, and in core-collapse supernovae. It is found that spin magnetization influences the criteria for instability and hence the properties of MHD waves in the degenerate plasma.
Measuring the Mass of Missing Baryons in the Halo of Andromeda Galaxy with Gamma-Ray Observations
Authors: Zhang Yi , Liu Ruo-Yu , Li Hui , Shao Shi , Yan Huirong , Wang Xiang-Yu
Published: April 2021

It has been suggested that a huge amount of baryon resides in the circumgalactic medium (CGM) extending out to the virial radii of galaxies. In this work we attempt to measure the baryon mass in the CGM with a novel method based on the gamma-ray observations of the extended halo of the Andromeda galaxy Messier 31 (M31). Since cosmic-ray particles generated inside the galaxy will eventually escape to the CGM, they will produce gamma-ray emission via the proton–proton collision with the CGM and produce gamma-rays. Different from some traditional measurements that are sensitive only to certain metallic ions in specific temperature range, the hadronic gamma-ray flux is sensitive to baryonic gases in all phases and does not rely on the metallicity in the halo, hence the measured gamma-ray flux from the galaxy’s halo can be used to constrain the mass of the CGM. By dealing with the cosmic-ray transport in the halo and calculating the hadronic gamma-ray intensity, we find that the total baryon mass contained within the virial radius is less than (1.4–5) × 1010
M
⊙ according to the gamma-ray intensity obtained with a model-dependent analysis. It implies that the CGM of Andromeda galaxy may not account for more than 30% of the missing baryons, but the result is subject to uncertainties from the gamma-ray intensity upper limit, diffusion coefficient of the cosmic-rays in the halo, as well as the stellar mass and dark matter halo mass of the galaxy. This method will become more constraining provided better understandings on these issues and more sensitive gamma-ray telescopes in the future.
A new species of Xylophis Beddome, 1878 (Serpentes: Pareidae) from the southern Western Ghats of India
Authors: Narayanan Surya , Mohapatra Pratyush P. , Balan Amirtha , Das Sandeep , Gower David J.
Published: April 2021

We reassess the taxonomy of the Indian endemic snake Xylophis captaini and describe a new species of Xylophis based on a type series of three specimens from the southernmost part of mainland India. Xylophis deepakisp. nov. is most similar phenotypically to X. captaini, with which it was previously confused. The new species differs from X. captaini by having a broader, more regular and ventrally extensive off-white collar, more ventral scales (117–125 versus 102–113), and by lack of flounces on the body and proximal lobes of the hemipenis. Phylogenetic analysis of mitochondrial 16S DNA sequences strongly indicates that the new species is most closely related to X. captaini, differing from it by an uncorrected pairwise genetic distance of 4.2%. A revised key to the species of Xylophis is provided.

Objective.

Due to no existing data, we aimed to derive evidence to support test-retest reliability for the Health Assessment Questionnaire–Disability Index (HAQ-DI) and 36-item Short Form Health Survey physical functioning domain (SF-36 PF) in psoriatic arthritis (PsA).

Methods.

We identified datasets that collected relevant data for test-retest reliability for HAQ-DI and SF-36 PF, and evaluated them using Outcome Measures in Rheumatology (OMERACT) Filter 2.1 methodology. We calculated intraclass correlation coefficients (ICC) as a measure of test-retest reliability. We then conducted a quality assessment and evaluated the adequacy of test-retest reliability performance.

Results.

Two datasets were identified for HAQ-DI and 1 for SF-36 PF in PsA. The quality of the datasets was good. The ICCs for HAQ-DI were good and excellent in study 1 (0.90, 95% CI 0.79–0.95) and study 2 (0.94, 95% CI 0.89–0.97). The ICC for SF-36 PF was excellent (0.96, 95% CI 0.92–0.98). The performance of test-retest reliability for both instruments was judged to be adequate.

Conclusion.

The new data derived support good and reasonable test-retest reliability for HAQ-DI and SF-36 PF in PsA.
Les relations dialectiques entre l’entrepreneuriat social et l’ESS au Maroc
Authors: Chapus Quentin
Published: April 2021

Le développement de l’entrepreneuriat social, dans son acception dominante d’origine anglo-saxonne (social entrepreneurship), divise parmi ceux qui défendent une pluralité des formes d’entreprendre : peut-il (re)dynamiser le secteur de l’ESS, ou bien s’agit-il d’une énième réinvention du capitalisme ? De telles positions gagnent à être étayées par des analyses contextualisées, ce que l’auteur réalise dans cet article à partir d’une enquête conduite au Maroc dans les années 2010, montrant que l’entrepreneuriat social y a d’emblée été bien plus proche du modèle porté par la start-up que de celui de l’entreprise sociale. Les « entrepreneurs sociaux » marocains témoignent ainsi d’une vision peu critique du capitalisme, bien que la recherche d’utilité sociale soit au cœur de leur engagement. Si, paradoxalement, cela participe à la marginalisation des structures de l’ESS, cet attrait pour le « social » pourrait être favorable à l’émergence de pratiques plus solidaires.

Polymethyl methacrylate (PMMA) is one among few known photo-polymeric resin useful in lithography for fabricating structures having better mechanical properties to meet the requirement in electronics and biomedical applications. This study explores the effect of Photo Initiator (PI) concentration and also curing time on strength and hardness of Polymethyl methacrylate (PMMA) obtained by UV photopolymerization of Methyl methacrylate (MMA) monomer. The UV LED light source operating at the wavelength of 364 nm is used with Benzoin Ethyl Ether (BEE) as photo initiator. The curing of PMMA resin is supported with peltier cooling device placed at the bottom of the UV light source. The characterisation study of UV photo cured PMMA is analysed through nano indenter (Agilent Technologies-G200). The current work investigates the influence of PI concentration and curing time in achieving maximum mechanical properties for UV photopolymerized PMMA.
State of Art on Vapour Smoothing of Fused Deposition Modelling Components
Authors: Basha S.M. , Basha M.M. , Venkaiah N. , Shankar M.R.
Published: April 2021

Fused Deposition Modelling (FDM) is one of the additive manufacturing processes which can produce prototypes or functional components without the use of fixtures, and the lead time required is reduced drastically compared to traditional machining processes. The application of the FDM process in the biomedical and casting industries is limited by its poor surface roughness which is most generally caused by the staircase effect and chordal error of the 3D model. Owing to the drawbacks of mechanical based finishing techniques, researchers have come up with a new technique known as Vapour Smoothing (VS). In this work, past literature of the VS process of FDM components is reported and it has been seen that the VS process is giving a promising improvement in surface roughness of FDM components.
Novel Studies on Thermo-Mechanical Properties of Structural Glass with and without Lamination
Authors: Nagamadhu M. , Kivade S.B.
Published: April 2021

The attractiveness of glass is something that occupied the world market with a unique claim. It has many applications that go beyond the provision of visual aesthetics, which includes a view of the inside and out. Due to extreme levels of clarity, structural glazing may be so transparent that it may go unnoticed by design or make a strong visual impact such as the focal point of a building. This paper focused on structural glass with various laminated/laminated conditions that were used to investigate the Dynamic Mechanical Properties. The storage modulus (G'), loss modulus (G'') and damping factor (tan delta) were determined at various levels, ranging from room temperature to elevated temperatures (250 °C) to understand the behavior of glass structure with and without laminated glass over a range of temperatures. The G' & G'' were tested to understand the effect of bonding, fracture behavior between the pure glass and laminated glass to observe the response with respect to temperature. Results are found that G' and G'' improve over a range of temperatures for laminated glass with enlightening fracture behavior. Laminated glass also has a major influence on the damping factor, but it also depends on the laminated thickness and materials. Thermo-Mechanical Properties of laminated glass are more improved, without affecting the transferability of glass.

Effect of Titanium Addition on Cracks of Fe-Cr-C Coating by Reactive Plasma Cladding
Authors: Liu Jun Bo , Wang Li Mei , Liu Jun Hai
Published: April 2021

Fe-Cr-C and Fe-Cr-C-Ti coatings were prepared by reactive plasma cladding in this paper. The crack morphology and fracture surface of the Fe-Cr-C coating were observed by SEM. The effect of titanium addition on the crack of Fe-Cr-C coating was analyzed. The results show that the coating cracks mainly consist of crack perpendicular to the fusion line, defect-induced crack and intergranular crack. The crack rate of Fe-Cr-C-Ti coating was obviously decreased after Titanium was added. When the titanium content is below 8 wt.%, with the increase of titanium content, the crack rate of Fe-Cr-C-Ti coating decreases obviously. When titanium content is between 8wt.% and 13wt.%, there are no cracks in the Fe-Cr-C-Ti coating. When the titanium content exceeds 13 wt.%, with the increase of titanium content, a small number of cracks begin to appear. The addition of titanium increases the toughness of the Fe-Cr-C-Ti coating and reduces the stress concentration.

Background

Communication is a bridge of transaction between the health team, patients, and families that applies in the service units of hospitals, which are closely related to the patient safety culture. TeamSTEPPS is a team strategies and tools to enhance performance and patient safety. Therefore, this study aims to analyze the effect of modified TeamSTEPPS training on the team communication of nurses in hospitals.

Design and methods

This study used a quasi-experimental pre-post-test control group design and a purposive sampling technique.

Results

About 28 nurses participated and were distributed into control and intervention groups. The results of the Wilcoxon test on communication perception obtained a p-value greater than α (0.980>0.050), while on communication attitudes the p-value was greater than α (0.517>0.050). Furthermore, the spearman rho test showed that there was no difference between the team perception (p=0.624; α=0.050) and communication attitudes (p = 0.320; α = 0.050). This means that the implementation of this training towards nurses’ Team communication in the hospital did not have a significant effect.

Conclusions

Hospitals need to carry out the implementation of TeamSTEPPS in a sustainable manner and develop good teamwork and effective team communication.

Authors: Lorensia Amelia , Budiono Ryanto , Suryadinata Rivan Virlando , Tiarasari Navy
Published: April 2021

Background

The consumption of EPA (Eicosapentaenoic acid), and DHA (docosahexaenoic acid), from fish oil, in the long run, has been observed to have a positive impact on patients with coronary heart disease. Fish oil products, with so much EPA and DHA content are available, and have very variable prices. Therefore, as a therapy to be used for long-term treatment, the cost factor is to be considered.

Design and methods

This study analyzed the content of EPA and DHA, using GC-MS. The sample to be analyzed was the fish oil that has the lowest price (Product A1), and that of the highest (Product A2). Furthermore, the macroscopic analysis was performed, by observing the physical form including organoleptic and qualitative tests, by reading the fragments identified by EPA and DHA.

Results

Clinical trials were conducted on patients (about 46 people), with risk factors and dyslipidemia. Product A1 showed EPA at tR= 15.574 min (relative%= 88.49%, similarity= 95%), and DHA at tR= 21.714 min (relative%= 88.92%, similarity= 93%). Product A2 showed EPA at tR= 28.719 min (relative%= 22.58%, similarity= 89%), and DHA at tR= 32.327 min (relative%= 22.87%, similarity= 90%), which meant that both had EPA and DHA contents, in accordance with their labels. Both products were confirmed to reduce total cholesterol in 4weeks (p=0.000, p= 0.000), with no significant difference in their effectiveness (p=0.652).

Conclusion

The results showed that both the A1 and A2 products, had the EPA and DHA contents in accordance with their respective labels. However, with the A2 product having a percentage relatively higher than that of the A1 brand, both are equally very effective.

Authors: Pradana Putri Anggie , Rong Jin-Ru
Published: April 2021

Stunting, a global issue, is the retarded growth and development of children resulting from inadequate nutrition, frequent infection, and insufficient psychosocial stimulation. It is usually an indicator of poor parenting. The role of parents is important for children's growth, development and learning. Parenting functioning is a concept health care professionals use to describe parenting activities for the purpose of intervention. But, the health professionals and patients have different understanding on parental functioning. There is a need to have a consistent definition of parenting functioning, and therefore this study aims to analyze the concept. Walker and Avant's method of concept analysis was used to study parenting functioning for the purpose of improving management of stunting. The attributes of parenting functioning are knowledge, competency, effort, responsibility, partnership, caring, teaching and communicating. Antecedents for parenting functioning are relationship, children's characteristics, careful observation and vicarious experiences. The consequences are positive child-rearing practice, less psychological stress and children's wellness. The empirical referents for parenting functioning are Keys to Interactive Parenting Scale (KIPS) and Parenting Interaction with Children: Checklist of Observations Linked to Outcomes (PICCOLO). In conclusion, this analytical concept can provide insights into nursing and public health colleagues to improve understanding of parenting functioning and to facilitate development of instrument to improve to an advance stage and to improve the stunting management.

Authors: Ningrum Evi Harwiati , Evans Sue , Soh Sze-Ee , Ernest Arul
Published: April 2021

Background

The measurement of nurse perception on safety, and the factors associated to safety climate, direct the development of effective strategies in reducing adverse events, and patient safety improvement.

Design and Method

This research was quantified, using the teamwork and safety climate domains of an Indonesian translated version of the Safety Attitudes Questionnaire (SAQ-INA). The teamwork and safety climate domain scores were calculated, using the published SAQ-INA scoring algorithm. The univariate and multivariate median regression models were performed to examine the association between potential predictors and safety climate.

Result

The results showed that 279 nurses responded to the survey (82% response rate). While most of them had a positive attitude towards teamwork (n=170, 61%), fewer possessed the same mentality towards safety climate (n=109, 39%). The lowest level of teamwork was perceived by nurses working in the emergency department (median 71, interquartile range 12.5), and safety climate (median 64, interquartile range 14.2). Furthermore, those that worked in the private hospitals, also reported lower levels of safety climate, compared to nurses in the public health centres (median difference=-3.571, p=0.009).

Conclusion

Ward and hospital type were associated with the level of safety climate, perceived by nurses. Understanding the key areas, the intervention is best directed to target hospital wards with poor safety climate, in a bid to reduce adverse events, and improve patient safety.

Authors: Setyawan Febri Endra Budi , Lestari Retno
Published: April 2021

Background

Malnutrition has been identified as the leading cause of illness and death in almost half of children under 5 years. Hence, to prevent the impact of malnutrition on physical and psychological development, family physicians need to explore new approaches in the health care delivery models that go beyond the scope of practice. A holistic-comprehensive approach will help the physicians develop a more thorough assessment of nutritional status. This study aims to determine factors associated with the nutritional status of children under five years using holistic-comprehensive approaches.

Design and methods

A case–control design was implemented, with emphasis on the identification of cases and control groups; 48 children confirmed malnutrition cases and 48 control without malnutrition were recruited from a Community Integrated Health Center in East Java, Indonesia. The characteristics of agent, host and environment between groups were compared and analyzed using correlation coefficients, odds ratio, logistic regression analysis, and Structural Equation Modeling-Partial Least Square (SEM-PLS).

Results

The SEM-PLS results showed that environmental factors have a greater influence on nutritional status (t-value >1.96), compared to the host factors. Furthermore, environmental factors having significant associations with nutritional status were poor socioeconomic status, low maternal educational level and not having exclusive breastfeeding. Also, the results of correlation coefficients and OR showed that birth weight (p=0.000, OR=33) and socioeconomic status (p=0.000, OR=22.3) had strong correlations with nutritional status.

Conclusions

Holistic-comprehensive approaches can be used as new ways to determine factors that may be associated with nutritional status of children under 5 years of age.

Authors: Ferinauli Ferinauli , Narulita Sari , Hijriyati Yoanita
Published: April 2021

Background

Background: Management of schizophrenia using psychopharmaceuticals requires a long-term treatment. The use of antipsychotic drugs can cause the occurrence of orthostatic hypotension, which leads to the risk of falling in patients. The aim of this study is to determine the effect of the use of antipsychotic drugs and orthostatic hypotension on the risk of falling in schizophrenic patients.

Design and methods

This study used a descriptive design with 53 respondents. Data were analyzed using the contingency coefficient correlation and Spearman Rank test methods.

Results

The results of the first study showed no positive effect between the use of antipsychotics on orthostatic hypotension in schizophrenic patients. In addition, a contingency coefficient correlation (C) of 0.199 and p-value of 0.335 (p>0.05) was obtained. The results of the second study showed that there was a significant positive effect between orthostatic hypotension on the risk of falling in schizophrenic patients with a value of r = 0.483 and a pvalue of 0.000 (p0.001).

Conclusion

It was suggested that the development of this study's result is needed for further research in dealing with the incidence of orthostatic hypotension in order to prevent or reduce the risk of falling in schizophrenic patients.

Published: April 2021

There have been an increasing overweight and obesity in very anxious children. Furthermore, obesity is a condition that occurs due to the accumulation of excess or abnormal fat. This disorder is believed to be the most significant public health problem that affects children in the 21st century. This study aimed to examine the literature review, articles and research results analyzing the effectiveness of family or parent empowerment interventions through health education. Many research articles were searched on several databases such as PubMed and PreQuest, using the following keywords which include “family empowerment”, “overweight”, “obesity”, “health lifestyle”, “BMI”, “children”, “RCT” starting from 2014 to 2019. The searched results obtained 162 articles on family empowerment, overweight and obesity. Out of the 162 articles, 20 were selected that discussed family empowerment interventions for overweight and obesity. Critical analysis of the 20 articles was carried out based on design, sample, treatment, parameters, findings and conclusions. The literature review analysis showed that family empowerment interventions in the form of health education or promotion activities vary widely in terms of methods, components, duration, individuals involved, specificity and effectiveness. Furthermore, this intervention consists of training activities, courses, and teaching practices. Statistical analysis showed that all these methods significantly increased the ability and independence of the family in controlling overweight and obesity. In conclusion, health education interventions that are packaged in various programs are proven to significantly improve the ability of families or parents in preventing and controlling overweight and obesity in children.

Authors: Manistamara Halidah , Sella Yurike Olivia , Apriliawan Sony , Lukitasari Mifetika , Rohman Mohammad Saifur
Published: April 2021

Background

Chest pain is considered one of the crucial indicators in detecting acute coronary syndrome (ACS), and one of the most common complaints frequently found in hospitals. Atypical characteristics of chest pain have prevented patients from being aware of ACS. Chest pain symptoms have become ambiguous, particularly for specific parameters, such as gender, diabetes mellitus (DM), or other clinical conditions. Therefore, it is critical for high-risk patients to have adequate knowledge of specific symptoms of ACS, which is frequently associated with late treatment or prehospital delay. Therefore, this study aims to identify the particular characteristics of chest pain symptoms in DM and non-DM patients with ACS.

Design and methods

This is a quantitative and non-experimental research, with the cross-sectional approach used to carry out the analytical observation at a general hospital from January- April 2019. Data were obtained from a total sample of 61 patients, comprising 33 ACS with DM and 28 ACS non-DM patients.

Results

The result showed that the characteristic of patients with chest pain symptoms has a significant relation to DM and ACS. Therefore, non-DM patients with ACS are more likely to feel chest pain at moderate to a severe level, while ACS-DM patients are more likely to have low to moderate chest pain levels.

Conclusion

The significant differences in the characteristics of chest pain in DM and non-DM patients suffering from acute coronary syndrome are the points of location of chest pain radiating to the neck and quality of pain.
