Methods of substantiating the quantitative composition and estimating the values of reliability indicators of technical objects of aircraft computer network
Authors: Zhurbin S.A. , Kazakov G.V. , Koryanov V.V.
Published: September 2020

When designing complex organizational and technical systems, one of the main quality criteria is to meet the requirements for indicators characterizing the operational and technical level of the system. The task of substantiating these requirements has not been systematically approached. Requirements, most often, are presented empirically or using the apparatus of expert analysis. This is due to problems in the field of formalization of processes occurring in complex technical systems, difficulties arising in the construction of mathematical models and the development of criteria that allow optimizing information, technical, software, linguistic and other structures of ACS. The problem of substantiating the requirements should be solved using a systematic approach, and the whole set of properties, integral and partial indicators of the system should be taken into account. The study focuses on the approach to solving the problem of substantiating the requirements for reliability indicators of technical means of an organizational and technical system using the apparatus of continuous Markov processes. Time between failures and recovery time were used as reliability indicators. As a result, we found an analytical solution to the problem of substantiating the requirements for the reliability indicators of technical means and the characteristics of their performance, as well as the number of computer network workstations, necessary to meet the integral requirements for the ACS.
Analysis of the performance of electrodynamic tethers with autonomous electron generation
Authors: Bechasnov P.M.
Published: September 2020

Currently, electric rocket engines have largely reached the efficiency limits determined by the principle of rocket thrust. Electrodynamic tethers, interacting with an external magnetic field and actually being jet engines, are devoid of such restrictions. However, their thrust is limited by the concentration of the external plasma and depends on its fluctuations. The paper is the first to propose to create a current in the tether by propellant ionization, receiving a large thrust from a relatively short tether and a strong magnetic field deflecting charged cosmic particles. The numerical analysis showed that the length of the tether of hundreds of meters near the Earth provides a specific impulse of up to hundreds of kilometers per second and its proper acceleration of the power plant at a level of 0.01 m / s2, as well as protection of the central region of the tether from particles with an energy of more than 1 MeV. This makes it possible to consider it for maneuvering satellites with practically no restrictions on the delta-V, for performing fast high-energy inter-orbital flights and for radiation protection of a high-latitude orbital station. In the future, such a tether can be used for rapid deceleration of orbital objects, launching into geostationary orbit, interplanetary transfers and protection of objects from charged particles. The study describes possible areas of application and directions for further research of the concept of such a tether.
Acoustic emission as an information factor of dissipative processes in metal cutting
Authors: Yakubov Ch.F. , Kim V.A. , Bashkov O.V. , Komkova T.Yu.
Published: September 2020

The paper focuses on the issues of using acoustic emission signals as information characteristics of dissipative cutting processes. We analyzed time dependences of the root-mean-square values of the amplitudes (RMS) and energy-frequency distributions of the acoustic signals of the cutting process. Furthermore, we identified the ranges of frequencies, amplitudes and energies of acoustic waves, responsible for individual dissipative mechanisms of the cutting process. Findings of research show that technological media, depending on the composition and thermophysical properties, have a different effect on the processes of plastic deformation and fracture during cutting, which directly affect the energy-frequency distribution of the acoustic emission signal. We have come to a conclusion that, irrespective of the lubricating and cooling technological media used, the energy of acoustic signals, when cutting at a speed of 50 m / min, is 2.0‒2.5 orders of magnitude higher than when cutting at a speed of 75 m / min, which indicates a wider range of acoustic emission sources; in this case, the composition of the cooling lubricants significantly affects the energy of acoustic waves.

Se destaca la importancia de los diferentes niveles de las dimensiones ecológicas de la familia y se alerta sobre los efectos nocivos que tienen en los niños la pobreza extrema y las condiciones familiares de gran adversidad.
Nuevas interpretaciones de la psicología del desarrollo con relación a los determinantes de la conducta
Authors: Thorne Cecilia
Published: September 2020

El artículo presenta dos posiciones actuales que buscan explicar el desarrollo humano desde perspectivas diferentes. Por un lado, se presenta la posición de Scarr acerca de los efectos de los genotipos sobre el ambiente, donde el peso de la interpretación está dado en los aspectos hereditarios. Por otro lado, la teoría ecológica sustentada por Bronfenbrenner que define al desarrollo humano como una interacción entre la persona en desarrollo y su medio ambiente. La aurora discute algunos aspectos de ambas posiciones en los que sería importante profundizar para prevenir negativos y tener una mejor comprensión del desarrollo del niño, en países en vías de desarrollo.

Authors: Majluf Alegria
Published: September 2020

Con el fin de explorar las estrategias utilizadas por madres de CSE media y baja para afrontar la crisis económica actual se entrevistaron a 20 madres de cada estrato económico y se les administraron trespequeñas encuestas y la Escala F-Copes "Escala de Evaluación Personal del Funcionamiento Familiar en Situaciones de Crisis". Los resultados evidenciaron que ambos grupos económicos se vieron seriamente afectados económicamente debiendo reducir sus gastos en actividades virales tales como alimentación, vestuario y recreación. Las madres de CSE media recurrieron más a una estrategia de reestructuración del problema para hacerlo más manejable y las madres de CSE baja a la movilización familiar para obtener ayuda y a la evaluación pasiva. No difieren ambos grupos en la búsqueda de apoyo espiritual y social.

Authors: León Ramón , Martell Elena
Published: September 2020

La presente comunicación reporta los resultados de una investigación acerca de conductas verbales y no verbales percibidas como indicadores de envidia en un grupo de estudiantes universitarios deLima Metropolitana. 709 estudiantes (376 mujeres y 333 hombres) respondieron una escala de 31 ítemes preparados por los autores. Además, se les solicitó que se autoevaluaran en una escala de Oa 10 como envidiosos -no envidiosos, y que valoraran el grado de envidia en el Perú, asimismo en una escala de O a 10 (nada de envidia- demasiada envidia). Tanto hombres como mujeres puntúanbajo en la autovaloración de la envidia (mujeres 3.19 versus hombres 3.20}, pero atribuyen (en especial las mujeres) mucha envidia a los peruanos (mujeres 7.34 versus hombres 6.96; <0.05). La conductaconsiderada como más expresiva de envidia tanto por hombres como por mujeres fue "ponerse verde de envidia". La segunda "comentar con alegría los fracasos de una persona". Los autores formulan una serie de comentarios acerca de los hallazgos en el contexto de la realidad peruana.

Published: September 2020

El estudio investiga la depresión y el autoconcepto en grupos de niños Peruanos expuestos a situaciones socioafectivas negativas, destacando la importancia y características especificas de este desorden en el campo psicológico y clínico. Fueron seleccionados 35 niños institucionalizados, 30 niños de una zona marginal de Lima y 20 niños con diagnóstico de depresión; todos varones entre 8 y 14 años. Se estudió la correlación entre ambas variables, se comparó los puntajes a nivel intergrupal y se adaptó el CDI (Children Depressive Inventory, Kovacs, 1983). Se obtuvo una correlación negativa y significativa entre las variables de depresión y autoconcepto. Asimismo, se encuentra que la institucionalización y el bajo nivel socioeconómico tienen influencia en el grado de depresión hallado en los niños examinados, en cambio tienen poca trascendencia en el nivel de autoconcepto. La evaluación de la validez y confiabillidad de los instrumentos utilizados brinda resultados óptimos, presentándose datos adicionales importantes.

As a global epidemic, obesity is currently a significant public health challenge, especially in children. Childhood obesity is related to short term consequences, but also with an increased risk to develop many comorbidities in adult life, such as cardiovascular diseases, type 2 diabetes, strokes, and others. A cross-sectional study to assess the prevalence of normal weight, pre-obesity and obesity in school-aged children was designed. The final sample size analyzed included 81 participants (47 boys and 34 girls) aged between 6 and 14 years old. Pre-obesity and obesity were determined according to the BMI cut-off points adopted by the IOTF. Although no significant differences were found, the prevalence of pre-obesity and obesity for the total population studied was 16.00% and 6.20%, respectively, with 14.60%, and 4.30% for boys and 17.60% and 8.80% for girls. More girls were pre-obese and obese than boys except at ages 9 and 12. The same age that boys presented cardiometabolic risk associated with a WHtR>0.50. These results emphasize the importance of nutritional status assessment to develop appropriate actions to prevent childhood obesity.
The Diest Formation: a review of insights from the last decades

Published: September 2020

Research conducted since the 1960s on the upper Miocene Diest Formation in NE Belgium is reviewed and integrated. Their lithology unites the deposits of the glauconiferous Diest Sand in one formation, though biozones and internal sedimentary structures strongly suggest the formation may agglomerate the deposits of two separate, successive sedimentary cycles.
The lowermost cycle is thought to have deposited the "Hageland Diest sand" during the early or middle Tortonian. It contains the Diest Sand in the main outcrop area in Hageland, Zuiderkempen and central Limburg, and probably also the Deurne Member near the city of Antwerpen. It furthermore includes the lower part of the Dessel Member in the central Kempen and in the Belgian part of the Roer Valley Graben (RVG). The Hageland Diest cycle represents the infill of a large tidal inlet tributary to the southern North Sea bight, then situated over the southern Netherlands and the Lower Rhine embayment. The Hageland Diest sand has the composition of a marine deposit, yet the confined area of occurrence and the presence of tens of metres deep incisions at the base, set it apart. The confinement of the embayment, strong tides and a steady supply of coastal‐marine sand are invoked as the main driving forces that resulted in the distinctive geometry and internal architecture of the unit.
The upper cycle is associated with the "Kempen Diest sand", which is found in the subsurface of the RVG and the Noorderkempen. It has a late Tortonian to earliest Messinian age with progressively younger ages occurring to the NW. It encompasses the upper part of the Dessel Member and the overlying, coarser Diest Sand, and correlates to most or all of the thickly developed Diessen Formation in The Netherlands. It is the deposit of a prograding marine delta, containing both marine components and continental components fed by the palaeo‐Meuse/Rhine river mouths. Accommodation space kept increasing during deposition, due to subsidence of the deposition area, especially inside the RVG but also in the Noorderkempen.
Although there is a fair consensus on the above, many concrete points about the geometry and depositional history of the Diest Formation and even a definitive decision on its single or dual character remain to be sorted out.
In addition, this review excludes the Flemish Hills sand and the Gruitrode Member from the Diest Formation.

The advancement of Palembang City family planning programs was not followed by community participation in this program, particularly by young spouses. This is a fascinating topic of discussion as the government's failure in identifying the causes of the decrease in the participation rate in family planning would have consequences for choosing alternative policies and the policy targets are not eventually reached. Therefore, this study aims to provide alternative viewpoints in looking at options for not participating the family planning program, through the meaning of young spouses to the program. This study used a qualitative design by interviewing five young spouses. By using the theory of symbolic interactionalism, this research found that from the dimension of mind, children are an investment that can strengthen their relationship with God while lightening their lives in their pension time. While from the dimension of self, a spouse does not show spontaneity, impulsive, and creative as an individual, but shows themselves as a husband and wife where the decision is in a joint decision. Lastly, from the dimension of society, the informants tend to be closed in making decisions. In more detail, they decide based on the information they know. This indicates the ineffectiveness of information dissemination from government, religious leaders and the mass media. The practical implications of this research are meaning of the individual intersects with the community, so the government must improve the dissemination of information, more holistically, so that messages do not reach only the individuals concerned but the community at large. The results could be the key to enhancement of quality family in Palembang.

Authors: Widayati Palupi
Published: September 2020

This article explains about gender bias in the hospitality sector, through the recruitment process at the Hotel Grand Keisha Yogyakarta. The method used of this research is a qualitative description with participatory observation and interviews, involving six sources, each a male manager and a female staff member from three selected departments. The three selected departments are housekeeping, food and beverages service department (FBS), and human resources development (HRD). This research uses gender culture theory, gender bias, and employee recruitment. The results obtained that gender bias can’t be seen only on one side, only from the recruitment process, but gender bias also can be phased from the start of recruitment process untill the work prosess. The process of communication and patterns of interaction that occur between workers show a state of gender bias and show the point of views about gender. The highest degree of gender bias is seen from workers with staff and supervisor positions, while manager positions have a lower degree of bias. This research can be developed with doing interviews all departments or even comparing with other hotels with different concepts.

Published: September 2020

Online news portals are interesting objects to study because they are superior to traditional media. The presence of the web, makes many researchers see the emergence of new public spaces in which individuals can find and produce diverse information. The development of the media was interestingly researched on seven online news portals which became the pioneers of online media in Indonesia, namely Detik, Kompas, Republika, Okezone, Media Indonesia, Tempo and VIVA . The purpose of this research is to find out media competition by using niche theory perspectives in two aspects namely niche breadt and overlap niche from Detik, Kompas, Republika, Media Indonesia, Okezone, Tempo and VIVA in terms of message distribution. Researchers want to see how competition between online news portals is equally competitive with different media characteristics. The method used first is quantitative content analysis as initial data to calculate niche breadth and niche overlap, second niche breadth analysis, and thirdly niche overlap analysis of the seven online news portals studied.. The results show that media competition in the breadth niche is divided into two generalist parts and tends to be generalist. Generalists point out that online news portals do not depend on a single source of life support. The overlapping niche results show that the level of competition or overlap of the seven online news portals can be said to be high or tight. The high competition category is divided into three parts, namely, the highest, tend to be high and a little high.

Repetition (al-tikrār) represents one of the most artistic and stylistic phenomena in contemporary critical studies. It is achieved a creative and aesthetic value in the literary discourse since it reveals us about the underlying real contents behind this sort of discourse. This paper seeks to monitor 'Repetition' types and their impact in the formation of poems of Bashīr al-Ḥāj Ghāji through the investment of principles and mechanisms of the artistic approach in the structure analysis of the repetition in his poems. They are many types such as repetition in letter, word and phrase as well as derivational repetition. It was due to that repetition those structures the obvious impact in the giving of some of his poems a rhythmic dimension and a musical tune which share in the overall rhythmic structure as well as achieved some of the its semantic purposes which the poet tried to express it and deliver it to the recipient.

Published: September 2020

Background:

Surgical treatment of femoroacetabular impingement (FAI) continues to evolve and is most commonly approached with either hip arthroscopy (HA) or surgical dislocation (SD) of the hip. The purpose of this study was to compare the outcomes of similar patients undergoing surgical treatment of FAI with either HA or SD.

Methods:

A prospective multicenter cohort study of patients undergoing primary surgical treatment of FAI was performed. Follow-up at a minimum of 1 year (mean, 4.3 years) was available for 621 hips (81.7%), including 399 procedures with HA and 222 procedures with SD. Propensity scores were calculated and reflect the likelihood of surgical treatment with HA versus SD for a given set of covariates. Propensity scores allowed 1:1 matching to identify similar patients at baseline. After propensity matching, 128 matched pairs of patients who underwent HA and 128 matched pairs of those who underwent SD were included in the study. The primary outcome was the postoperative modified Harris hip score (mHHS); secondary outcomes included the Hip disability and Osteoarthritis Outcome Score (HOOS), the University of California Los Angeles (UCLA) activity score, and the Short Form-12 (SF-12) physical and mental subscores, as well as the rate of persistent symptoms, revision surgery, and total hip arthroplasty (THA).

Results:

After propensity matching, the 2 groups exhibited similar distributions of all of the covariates that were included in the model. Both groups demonstrated significant improvements in all patient-reported outcomes (PROs). The final mHHS was not significantly different between the 2 matched groups (81.3 for the HA group versus 80.2 for the SD group, p = 0.67). Likewise, the HOOS pain subscale was similar at the time of final follow-up (77.6 versus 80.5, respectively, p = 0.32). No difference between the HA group and the SD group was identified in the rate of THA (0% and 3.1%, respectively, p = 0.41) and revision surgery (7.8% and 10.9%, respectively, p = 0.35); overall rates of persistent symptoms were 21.9% for the HA group and 24.4% for the SD group (p = 0.55).

Conclusions:

In a propensity-matched analysis of patients who were treated with either approach, patients undergoing HA or SD demonstrated similar outcomes at a mean of 4 years postoperatively.

Análisis de la verificación de los avisos meteorológicos por temperaturas máximas en la Región de Murcia (2010–2017)
Authors: Martí Talavera Javier , Moltó Mantero Enrique , Sánchez Almodóvar Esther
Published: September 2020

El uso de los datos climáticos de más de 90 observatorios meteorológicos repartidos en la Región de Murcia, ha permitido tener una muestra muy heterogénea de las temperaturas máximas, teniendo en cuenta distintos entornos, tanto urbanos, como naturales. La relación entre los avisos emitidos por altas temperaturas y su comparativa con los valores finalmente observados ha permitido poder aplicar unos índices de verificación, que en algunos casos han tenido que ser modificados para su correcta aplicación, los cuales reflejan una notable sobreestimación de estas alertas, así como una mejora en el número de aciertos en los últimos años. La realización de la cartografía ha permitido localizar e identificar cuáles son las áreas donde existe, tanto una mayor anomalía térmica, como una menor incidencia de los distintos índices de verificación, pudiendo servir de ayuda para una revisión o mejora de los umbrales y zonificación de los avisos meteorológicos en esta provincia.
The genetic control of leaf and petal allometric variations in Arabidopsis thaliana

Published: September 2020

Background Organ shape and size co-variation (allometry) is an essential concept for the study of evolution and development. Although ample research has been conducted on organ shape and size, little of it has considered the correlated variation of these two traits and quantitatively measured the variation in a common framework. The genetic basis of allometry variation in a single organ or among different organs is also relatively unknown. Results A principal component analysis (PCA) of organ landmarks and outlines was conducted and used to quantitatively capture shape and size variation in leaves and petals of multiparent advanced generation intercross (MAGIC) populations of Arabidopsis thaliana . PCA indicated that size variation was a major component of allometry variation and revealed negatively correlated changes in leaf and petal size. After QTL mapping, five QTLs for the fourth leaf, 11 QTLs for the seventh leaf, and 12 QTLs for the petal size and shape were identified. These QTLs were not identical to those previously identified, with the exception of the ER locus. The allometry model was also used to measure the leaf and petal allometry covariation to investigate the evolution and genetic coordination between homologous organs. Totally, 12 QTLs were identified in association with the fourth leaf and petal allometry covariation, and eight QTLs were identified to associate with the seventh leaf and petal allometry covariation. In these QTL confidence regions, there were important genes associated with cell proliferation and expansion with alleles unique to the maximal effects accession. Besides that, the QTLs associated with life-history traits, such as days to bolting, stem length, and rosette leaf number, which was highly coordinated with climate change and local adaption, were QTL mapped and showed an overlap with leaf and petal allometry, which explained the genetic basis for their correlation. Conclusions This study explored the genetic basis for leaf and petal allometry and their interaction, which may provide important information for investigating the organ shape and size correlated variation and evolution in Arabidopsis .

Background: Sweetpotato (Ipomoea batatas L.) is one of the seven major food crops grown worldwide. Cold stress often can cause protein expression pattern and substance contents variations for tuberous roots of sweetpotato during low-temperature storage. Recently, we developed proteometabolic profiles of the fresh sweetpotatoes (cv. Xinxiang) in an attempt to discern the cold stress-responsive mechanism of tuberous root crops during post-harvest storage. Results: For roots stored under 4℃ condition, the CI index, REC and MDA content in roots were significantly higher than them at control temperature (13℃). The activities of SOD, CAT, APX, O2.- producing rate, proline and especially soluble sugar contents were also significantly increased. Most of the differentially expressed proteins (DEPs) were implicated in pathways related to metabolic pathway, especially phenylpropanoids and followed by starch and sucrose metabolism. L-ascorbate peroxidase 3 and catalase were down-regulated during low temperature storage. α-amylase, sucrose synthase and fructokinase were significantly up-regulated in starch and sucrose metabolism, while β-glucosidase, glucose-1-phosphate adenylyl-transferase and starch synthase were opposite. Furthermore, metabolome profiling revealed that glucosinolate biosynthesis, tropane, piperidine and pyridine alkaloid biosynthesis as well as protein digestion and absorption played a leading role in metabolic pathways of roots. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis. Conclusions: Our proteomic and metabolic profile analysis of sweetpotatoes stored at low temperature reveal that the antioxidant enzymes activities, proline and especially soluble sugar content were significantly increased. Most of the DEPs were implicated in phenylpropanoids and followed by starch and sucrose metabolism. The discrepancy between proteomic (L-ascorbate peroxidase 3 and catalase) and biochemical (CAT/APX activity) data may be explained by higher H2O2 levels and increased ascorbate redox states, which enhanced the CAT/APX activity indirectly. Glucosinolate biosynthesis played a leading role in metabolic pathways. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis.

Background: This study aimed to examine the cost-effectiveness of one-time standard endoscopic screening with Lugol’s iodine staining for esophageal cancer (EC) in China. Methods: A Markov decision analysis model with eleven states was built. Individuals aged 40 to 69 years were classified into six age groups in five-year intervals. Three different strategies were adopted for each cohort: (1) no screening; (2) one-time endoscopic screening with Lugol’s iodine staining with an annual follow-up for low-grade intraepithelial neoplasia (LGIN); and (3) one-time endoscopic screening with Lugol’s iodine staining without follow-up. Quality-adjusted life-years (QALYs) indicated the effectiveness of the model. The incremental cost-effectiveness ratio (ICER) was used as the evaluation indicator. Sensitivity analysis was performed to assess the robustness of the model. Results: One-time screening with follow-up was the undominated strategy for individuals aged 40-44 and 45-49 years, which saved USD 10,942.57 and USD 6,611.73 per QALY gained compared to nonscreening strategy. For those aged 50-69 years, the nonscreening scenarios were undominated. One-time screening without follow-up was the extended dominated strategy. Compared to screening strategies without follow-up, all the screening strategies with follow-up were more cost-effective, with the ICER increasing from 299.57 USD/QALY for individuals aged 40-44 years to 1617.72 USD/QALY for individuals aged 65-69 years. Probabilistic sensitivity analysis (PSA) supported the results of the base case analysis. Conclusions: One-time EC screening with follow-up targeting individuals aged 40-49 years was the most cost-effective strategy.

Background: The optimal hypothermic level in total arch replacement with stented elephant trunk implantation for acute type A aortic dissection (aTAAD) has not been established, and the superiority of unilateral or bilateral cerebral perfusion remains a controversial issue. Therefore, we evaluated the application of moderate hypothermic circulatory arrest (MHCA) with a core temperature of 29℃ and bilateral selective antegrade cerebral perfusion in aTAAD treated by total arch replacement with stented elephant trunk implantation. Methods: From July 2019 to January 2020, 25 aTAAD patients underwent total arch replacement with stented elephant trunk implantation via MHCA (29℃) and bilateral selective antegrade cerebral perfusion (modified group). Thirty-six patients treated by the same procedure with MHCA (25℃) and unilateral selective antegrade cerebral perfusion during this period were selected as controls. Results: There were no differences between the two groups of patients in terms of age, sex, incidence of hypertension, malperfusion, and pericardial effusion, although the incidence of cardiac tamponade was higher in the modified group (control 2.8%, modified 20%; P = 0.038). The lowest mean circulatory arrest temperature was 24.6±0.9℃ in the control group, and 29±0.8℃ in the modified group (P < 0.001). In-hospital mortality was 4.9% (3/61) for the entire cohort (control 8.3%, modified 0; P = 0.262). The incidence of permanent neurologic deficit was 4.9% (control 8.3%, modified 0; P = 0.262). There were no significant differences in the occurrence of temporary neurological deficit, renal failure, and paraplegia between groups. The rate of major adverse events in the modified group was lower (30.6% vs. 4%, P = 0.019). A shorter duration of ventilation and ICU stay was identified in the modified group, as well as a reduced volume of drainage within the first 48 h and red blood cell transfusion.Conclusions: The early results of MHCA (29℃) and bilateral selective antegrade cerebral perfusion applied in total arch replacement with stented elephant trunk implantation for aTAAD were acceptable, providing similar inferior cerebral and visceral protection compared with that of the conventional strategy. A higher core temperature may account for the shorter duration of ventilation and ICU stay, as well as a reduced volume of drainage and red blood cell transfusion.

Background: Chronic obstructive pulmonary disease (COPD) is a progressive lung disease commonly encountered in primary care. This study aimed to audit COPD care at primary care clinics of Hong Kong and to work out improvement strategies. Method: All COPD patients aged 40 or above who had been followed up at 13 public primary care clinics of Kowloon Central Cluster (KCC) under the Hospital Authority of Hong Kong (HAHK) were included in this clinic audit. Evidence-based audit criteria and performance standards were established after thorough literature review. Phase 1 was from 1st April 2016 to 31st March 2017, with deficiencies of care identified. It was followed by a one-year implementation phase through which a series of improvement strategies were executed. Outcome of the enhancement was reviewed during Phase 2 from 1st April 2018 to 31st March 2019. Chi-square test and student’s t test were used to detect statistically significant changes between Phase 1 and Phase 2. Results: A total of 2,358 COPD cases were identified in Phase 1 where 658 of them were smokers. Of those smokers, 332 (50.5%) had been referred to Smoking Counselling and Cessation Service (SCCS) and 289 (43.9%) actually attended it. 991 cases (42%) received Seasonal Influenza Vaccine (SIV) and 938 cases (39.8%) received Pneumococcal Vaccine (PCV). 698 patients (29.6%) had spirometry done before and 423 patients (17.9%) had been admitted to hospital due to acute exacerbation of COPD (AECOPD). With the concerted effort taken during the implementation phase, Phase 2 data showed significant improvement in nearly all criteria. There was a marked increase in the SIV and PCV uptake rate, spirometry performance rate and most importantly, a significant reduction in AECOPD rate leading to hospital admission (13.5%, P=0.000043). However, the referral rate and attendance rate of SCCS among smokers remained stagnant (P>0.05). Conclusion: Via a systematic team approach, COPD care at primary care clinics of KCC under HAHK had been significantly improved for most of the audit criteria, which in turn reduced the burden of the healthcare system.
