With the development of online shopping platforms, users are able to express their needs and feelings through online reviews. The analysis of comments from users can help to understand the real needs of users, the iteration of facilitate product and the service transformation of companies. The big data methods can be used to analyse user reviews, which can help designers gain the user needs on a macro perspective, while the traditional small data methods can help designers obtain the capture users’ implicit preferences and differential needs. Therefore, the fusion of large and small data methods can help designers to study user needs more foundly and accurately. Taking kitchen storage products as an example, this paper firstly crawled the product reviews on the Tmall website using big data methods and the sentiment analysis of reviews was detected. Then with introducing an LDA model for topic mining, the reviews of users were transformed into the demand characteristic words of products. By small data methods, the implicit needs of users were obtained by questionnaires and in-home research, and the results of big data methods was Validated and supplemented. In this paper, the user needs indicators of four types of kitchen storage products were obtained and prioritized according to the kano model and sentiment analysis.

Background: more than 50% of newly diagnosed primary open-angle glaucoma (POAG) patients are in the moderate or advanced stages. It is difficult to assess disease course due to limited official data. On a national scale, prevalence and incidence are measures that hardly provide a complete "landscape" of this issue in Russia. Aim: to determine the prognosis of changes in epidemiological indicators (prevalence and incidence) of POAG in Russia, assess disease duration and calculate presumed age of disease onset. Patients and Methods: we applied a scientific-analytical design implying literary statistical analysis of official epidemiological indicators of glaucoma in Russia and multicenter trials. These data were a basis for prediction (three variants) of glaucoma incidence and prevalence in Russia and the development of a mathematical model to determine the age of disease onset and duration. Results: the age of patients with POAG stage 0 was 54 (49;58) years. This age was calculated based on data from publications in 2000– 2016. These data were initially used to calculate the mean duration of each glaucoma stage. As a result, the "true" age of stage 1 onset was 57 (52;61) years. Meanwhile, the mean age of stage 1 diagnosis was 60 (56;65) years. According to these calculations and considering predicted changes in population size and average life expectancy, a growth in glaucoma incidence and prevalence is expected in low, medium, and high population projections. Conclusions: we demonstrated an expected growth in glaucoma incidence and prevalence in Russia in the coming 15 years. An increase in visual disability and, therefore, rapid loss of working capacity in various age groups due to "late" diagnosis and treatment are also likely. Collection of epidemiological data, further analysis of these findings, and searching for ways to improve diagnosis and course of socially significant diseases (e.g., glaucoma) are among strategic tasks for the healthcare system.

Residual astigmatism or ametropia are relatively common after phacoemulsification. This entity is accounted for by inaccurate intraocular lens (IOL) power calculation or improper preoperative examination. As a result, target refraction is not achieved. Spectacle correction of astigmatism in pseudophakia has several drawbacks and is often poorly tolerated, leaving patients unsatisfied with surgical outcomes. This paper reviews state-of-the-art surgical techniques for correcting residual astigmatism after cataract surgery. These include laser (photorefractive keratectomy/PRK and laser in situ keratomileusis/LASIK), Femto laser (arcuate keratotomy), and intraocular (add-on toric IOL implantation) procedures. The authors address published data on the pros and cons of these interventions. These techniques empower surgical correction of astigmatism and provide the best possible vision for patients. Finally, this paper discusses postoperative management using tear substitutes. Keywords: phacoemulsification, residual astigmatism, PRK, LASIK, femtosecond arcuate incisions, add-on toric IOLs.

La verdad histórica, sociológica y jurídica del ayuntamiento municipal dentro de la noción del federalismo mexicano
Authors: Del Rivero del Rivero José Alberto
Published: March 2022

La presente investigación tiene como objetivo principal dilucidar el trasfondo histórico, sociológico y jurídico que sustenta al ayuntamiento municipal como la primera esfera constitucional integrante del pacto federal en México, considerando que “sin Historia del Derecho, no hay Historia de la Civilización” (Levene, 1973, p. 8). A pesar de ello, en este artículo se argumentan las razones en virtud de las cuales esta esfera de soberanía municipal ha sido excluida constitucionalmente fuera de la noción del federalismo, contradiciendo el linaje histórico del municipio y, por ende, distorsionando la propuesta del Congreso Constituyente de 1916-1917, escenario que ha provocado en la práctica que se cometan invasiones a esta esfera por parte de la federación y los estados, asimismo, ha llevado a ubicar al gobierno municipal  en una situación de vasallaje petrificado contraria a la evolución del constitucionalismo, principalmente por lo que atañe al principio de división de poderes.

Authors: Idham Shebli Younus , SUBRAMANIAM ILANGKO , Aljangawi Rabaa Said Mohamed
Published: March 2022

This study aims to elicit information on the discursive methods used by the speakers who lead the congregational groups under inquiry. Additionally, the research attempts to demonstrate if the congregational group's ideology affects the discourse of the dispute. The study of sectarianism in congregational speeches can be derived from Wodak and Meyer's (2001) and Renkema's (2009) perspectives. According to Wodak (2005), five tactics may be employed to expose the influence wielded by specific individuals or organizations. According to Wodak and Meyer (2001), strategy refers to a (more or less precise and more or less purposeful) sequence of behaviours, including discursive acts, used to accomplish a specific social, political, psychological, or linguistic aim. Analyzing the speech in sectarianism can help understand relevant and crucial issues revolving around the speech in congregational groups. Linguistically, it is hoped to assist media audiences of sectarianism in congregational groups to critically and consciously interpret it in congregational groups about this discourse.

Los Estados como representantes de la aplicación de estas normas han exigido de sus representados la opción de obtener un apoderado en el litigio, contra ese Estado, o para con los particulares, de aquí surge la figura del abogado como representante del indiciado, intentando hacer la defensa con argumentos que la ley de imprime a sus planteamientos, disertaciones que darán al implicado la posibilidad de resolver sus angustias, y de ajustar su situación. Ese abogado deberá ajustarse a las limitantes que cada nación, en su desarrollo normativo impondrá. En Colombia, el control sobre las actuaciones de los abogados está plasmado en el código disciplinario del abogado incluido en la Ley 1123 de 2007, la cual indica de manera clara y sucinta los deberes e incompatibilidades en el ejercicio de su profesión, la ética, el profesionalismo y, ante todo, su actuar dentro del marco de legalidad, estos son los factores más relevantes para una buena práctica del derecho.

Objective: To examine the level of burnout syndrome, and to investigate the relationship between burnout, personality traits, coping strategies, and other related personal factors among mental health professionals working in a tertiary hospital.Materials and Methods: Online questionnaires were sent to 160 mental health professionals at Siriraj Hospital. The questionnaire comprised questions collecting demographic data, the Copenhagen Burnout Inventory (Thai version), the Big Five Inventory, and the Coping Scale. The data were analyzed through descriptive statistics, analysis of variance, Pearson correlation, and stepwise multiple regression.Results: A total of 121 (75.6%) responses were collected. Of the 121 participants, 41.3% reported high total burnout levels. However, no difference in total burnout was found between the different mental health professions. The group aged between 20-29 years demonstrated higher burnout than the others. Individuals with bachelor’s and master’s degrees showed greater burnout than those with lower than undergraduate degrees. Moreover, individuals who worked for less than five years had higher burnout than those in other groups. Furthermore, neuroticism and avoidance significantly predicted the burnout syndrome.Conclusion: In contrast to previous studies in Thailand, the results highlighted the risk factors for burnout syndrome in terms of personal, work-related, and client-related burnout. These results can strengthen awareness surrounding mental health conditions, for the effective provision of psychoeducation and psychological interventions.

Published: March 2022

Objective: To identify the attitudes toward long-acting injectable antipsychotics (LAIs) among schizophrenia atthree psychiatric outpatient clinics in Southern Thailand from February to April 2021.Materials and Methods: A study was conducted at three psychiatric outpatient clinics. All patients, who met the criteria of having schizophrenia based on ICD-10 criteria, aged 20-60 years were included. The questionnaires utilized were:1) Demographic information, 2) Profile of schizophrenia disorder, and 3) Attitude, knowledge, and satisfaction towards LAIs. All data were analyzed using descriptive statistics.Results: There were 259 participants who completed the questionnaires. From the participants, 39% had a history of being treated with LAIs. A quarter of them felt LAIs made them feel stigmatized (26.3%), that they lost autonomy (24.7%), and embarrassed (16.6%). The reasons for refusing to receive LAIs were not fear of needles or pain at the injection site (49%), but rather that LAIs had more adverse effects than oral medications (47.9%). Half of them (51.8%) knew that they must continue to use LAIs, even though their symptoms had improved as LAIs played an important role by improving their symptoms (68.8%), and preventing relapse (51.8%). They were satisfied about having been involved in the decision making of using LAIs for their treatment (63.6%), having information on therisk-benefits from LAIs provided to them (72.3%), and the cost of LAIs (75.2%).Conclusion: Before deciding to prescribe LAIs, we should ensure that all patients receive information about the risks, and benefits of LAIs, boosting acceptance for this formulation and mitigating concerns about patient autonomy reduction and stigmatization.

This report describes the development of functionalized polymeric micelles encapsulating a chemotherapeutic agent. The results indicate the ability to achieve selective uptake into different cell populations in metastatic prostate cancer in vitro by appropriate selection of the targeting ligand. This paves the way for administering single or multiple therapeutic agents into bone metastases. These particles are functionalized to display the pVTK peptide of bisphosphonate (BP) as two different targeting ligands to assess their ability to trigger selective binding and internalization into prostate cancer cells, osteoblasts, osteoclasts, and macrophages in vitro. These bone-targeting particles (60-90 nm) bind to hydroxyapatite/bone powder with high affinity. Uptake of pVTK- and BP-conjugated particles into prostate cancer cells (PC-3 and C4-2B), MC3T3, RAW264.7 bone macrophages, and RANKL-activated RAW264.7 cells cultured on a regular tissue culture plate and bone-like surface was investigated. Results show that increasing the number of BP-targeting ligands displayed on particle surface shows 60-fold higher affinity to RAW 264.7 macrophages seeded on conventional tissue culture plates than non-conjugated particles. In addition, the uptake study results show that pVTK-functionalized particles were selectively internalized by C4-2B and MC3T3 osteoblast cells cultured on BLS, whereas BP-functionalized particles are selectively internalized by PC-3 and RAW264.7 macrophage cells cultured on BLS. Therefore, efficient and selective bone-conjugated therapies are needed to kill cancer cells and inhibit the crosstalk with other cells in the metastatic lesion, resulting in osteoblastic, osteolytic, or a mixed phenotype.
