Published: January 2023

Se evaluaron las características fisicoquímicas (TDS, EC, salinidad y temperatura) de la Laguna de Ñahuimpuquio del Departamento de Junín en Perú. Se realizó el monitoreo en el segundo semestre del 2021: 2 meses del período seco (agosto y septiembre) y 2 meses del período lluvioso (octubre y noviembre), en 5 puntos claves dentro de la laguna; punto 1: Zona de embarcadero; punto 2: Manantial natural “Puquio” que alimenta a la laguna; punto 3: zona de recreos turísticos y venta de alimentos; punto 4: zona de desembocadura de la laguna; y el punto 5: centro de la laguna de Ñahuimpuquio. Los resultados muestran que el total de sólidos disueltos según la norma NPDWR de USA, ubica el agua de la Laguna de Ñahuimpuquio en un nivel de calidad aceptable para suministro de red, y calidad aceptable para agua purificada de garrafón y/o agua embotellada. La salinidad en la laguna oscila entre 297,2 – 312,2 μS/cm; se considera dentro de los parámetros de Digesa (700 – 1200 μS/cm), lo que indica que la laguna tiene baja toxicidad de iones. La conductividad eléctrica del agua de la laguna muestra valores entre (282 – 303,6 de CE), clasificándose como “Buena”. En cuanto a la temperatura, los resultados muestran unos valores desde (18,52 °C – 24.66 °C). Finalmente se demostró que existen correlaciones significativas entre el turismo de la laguna y el incremento de la temperatura, coductividad eléctrica y el total de sólidos disueltos; mas no existe relación con la salinidad en la laguna de Ñahuimpuquio - Ahuac.

Gender Attitudes Across Generations in Contemporary Armenian Society (Comparative Analysis)
Authors: Zaslavskaya Maria , Agadjanian Victor
Published: January 2023

Contemporary gender norms and attitudes in Armenia have been shaped by a complex interplay of pre-Soviet traditional culture, the legacy of the Soviet socialist modernization project, and the post-Soviet spread of western ideas and values. The paper examines generational differences in gender norms and attitudes in Armenian society, by comparing three generational groups. The mixed-method analysis is based on quantitative and qualitative data, including the nationally-representative household-based Gender Barometer Survey conducted in 2014, as well as in-depth interviews and focus group discussions among members of different generational groups in Armenia during 2015-2020. The results of the factor analysis show considerable generational complexity in gender norms and attitudes. We find that the majority of Armenian society, regardless of gender and generation, strongly adheres to the core family values and the corresponding gendered family roles. At the same time, the analyses show that individuals who belong to the older generation, i.e., the generation whose socialization took place under Soviet rule, display the most conservative patriarchal gender attitudes. The middle generation, whose coming of age occurred during the period of the early radical post-Soviet transformation, demonstrate inconsistent gender attitudes: while adhering to conservative gender norms, they are also most dissatisfied with the state of gender equality and in some aspects, such as achievement of status and wealth, display considerable gender egalitarianism. Finally, the youngest generation generally subscribes to the most egalitarian attitudes, but this group is far from homogenous, demonstrating a sharp divide between urban dwellers, who are very egalitarian-minded, and rural ones, who are remarkably conservative. Notably, young women living in cities display by far the most egalitarian attitudes. Moreover, among men, the generation is not a significant predictor of the level of egalitarianism in gender attitudes, compared to education and area of residence (city/village). However, it has a more significant impact on women’s perception of the traditional gender scheme. We conclude with a discussion of the role of changes in gender norms and attitudes in a broader transformation of Armenian society.

Personality Detection on Twitter Social Media Using IndoBERT Method
Authors: Rohmah Tri Ayu Syifa'ur , Maharani Warih
Published: January 2023

Personality is the fundamental characteristic of human beings that makes humans unique. Because of these differences in human characteristics, personality becomes a benchmark for consideration in various recruitment processes. One way to predict personality is to apply an interview system or fill out questionnaires which often experience problems due to ineffectiveness in terms of time and cost. Results become inaccurate if prospective employees do not know themselves well. The big five personality method, divided into openness, conscientiousness, extraversion, agreeableness, and neuroticism, is widely used to predict personality. This study uses a deep learning method, IndoBERT, to detect personality based on five dimensions according to the big five personalities whose data is taken from Twitter tweets with crawling data. From the results of these studies, it is known that personality research using the IndoBERT method without a stemming process has a higher accuracy rate of 0.46.

Published: January 2023

The movie recommender system is a technology designed to make it easier for users to provide recommendations quickly and among the many pieces of information. Because the number of movies is huge, it causes a person to be confused in determining the choice of the movie to watch. Many movie recommending systems have been developed, but users cannot interact intensively. Based on these problems, we developed a chatbot-based conversational recommender system, which can interact intensively with the system. The developed chatbot uses normal language handling to permit the framework to comprehend what the user enters as natural language. POS Tagging is used to find tags in the form of movie titles with patterns in the POS Tagging model. However, the algorithm of those used on POS Tagging does not pay attention to the sentence entity, so the predicted title must correspond to the provisions of POS Tagging. Multinomial Naive Bayes looks for similarities of user input to datasets on intents. The dataset with the highest probability value or almost equal to the sentence entered by the user can be used as a response to user input. The test results of the chatbot application showed that the match rate between response and user input was 89.1%. Thus, the developed chatbot can be used well to provide practical and interactive movie recommendations.

Authors: Kabul Muhammad Shiba , Setiawan Erwin Budi
Published: January 2023

Netflix is one of the most widely used applications for watching movies online. There are various movie titles that can be watched by users, so a recommendation system is needed to help users who feel confused in choosing movie titles. Twitter is a social media used to express ideas, thoughts, and feelings. Not a few Twitter users who conduct movie discussions, with the movie discussion can be converted into a rating that can be used in the recommendation system. Collaborative Filtering is one of the methods of the recommendation system, by recommending based on the similarity between users (user-based) and based on items that have similarities with user-selected items (item-based). In this research, the Collaborative Filtering method is combined with K-Nearest Neighbors classification which obtains an RMSE value for user-based 1.8244 and item-based 0.5449. K-Nearest Neighbors gets 91.22% precision and 91.07% recall for user-based, while item-based gets 89.44% precision and 91.22% recall with the optimal K as a parameter is 3.
Multi-disease Health Screening in an Urban Low-income Setting: A Community-based Study
Authors: Wee Liang En , Koh Gerald CH , Toh Zheng Jie
Published: January 2023

Introduction: We were interested to determine the participation rates for health screening in a multi-ethnic urban low-income community. We assessed the health screening rates at baseline, collected data on reasons for non-participation and assessed the impact that a 5-month intervention had on health screening in this community. Materials and Methods: The study population involved all residents aged ≥40 years, living in heavily subsidised public rental flats in Taman Jurong Constituency, Singapore. From January 2009 to May 2009, we collected baseline information and offered eligible residents free blood pressure, fasting blood glucose and lipid measurements, fecal occult blood testing and Pap smears. Screenings were conducted either at or near the residents’ homes. Results: The participation rate was 60.9% (213/350). At baseline, 18.9% (24/127), 26.4% (42/159) and 18.7% (31/166) had gone for regular hypertension, diabetes and hyperlipidaemia screening, respectively; 3.8% (6/157) and 2.9% (2/70) had had regular colorectal and cervical cancer screening, respectively. Post-intervention, rates for hypertension screening increased to 97.6% but increases for other modalities were marginal. High cost, lack of time, not at risk, too old, or unnecessary for healthy people were commonly cited reasons for skipping regular health screening. Being unemployed was associated with missing regular hypertension screening (adjusted OR = 2.48, CI = 1.12-5.53, P = 0.026); those who did not need financial aid were less likely to miss regular hyperlipidaemia screening (adjusted OR = 0.27, CI = 0.10-0.72, P = 0.008). Conclusion: The participation rates for health screening were poor in this low-income community. More can be done to encourage regular health screening participation amongst this segment of the populace, both by reducing costs as well as addressing misperceptions.

Authors: Hong Wei Wei , Ang Li Wei , Cutter Jeffery L , James Lyn , Chew Suok Kai , Goh Kee Tai
Published: January 2023

Introduction: We presented the findings from 2 seroprevalence studies conducted 6 years apart, so as to determine changes in the hepatitis B surface antigen (HBsAg) positivity rate and immunity to hepatitis B virus (HBV) among Singapore residents aged 18 to 69 years, and to assess the impact of a 4-year catch-up hepatitis B immunisation programme for adolescents and young adults launched in 2001. Materials and Methods: Two hepatitis B seroprevalence studies (HBSS) were conducted in 1999 and 2005 based on stored blood samples collected from 4698 participants aged 18 to 69 years during the national health survey (NHS) 1998 and from 3460 participants during the NHS 2004, respectively. Serology for HBsAg, hepatitis B e antigen (HBeAg) and antibody to HBsAg (anti-HBs) were tested by enzyme immunoassay in HBSS 1999 and electrochemiluminescence in HBSS 2005. Results: The overall age-standardised prevalence of HBsAg among Singapore residents aged 18 to 69 years decreased significantly from 4.0% in HBSS 1999 to 2.8% in HBSS 2005 (P = 0.002). The age-standardised prevalence of HBsAg in males (4.9% in 1999) and Chinese (4.7% in 1999) both decreased significantly to 2.7% and 2.8%, respectively in 2005. The overall age-standardised population immunity to HBV (anti-HBs >10mIU/ml) increased from 39.7% in 1999 to 42.1% in 2005 (P = 0.019). In particular, the age-specific prevalence of anti-HBs showed a significant increase among those in the age group of 18 to 29 years from 27.9% in 1999 to 41.7% in 2005 (P <0.001) and among those in the age group of 30 to 39 years from 39.9% in 1999 to 44.7% in 2005 (P = 0.021). Conclusion: There was an overall decline in the HBsAg positivity rate as well as an overall increase in population immunity to HBV. Following the 4-year catch-up immunisation programme, there was a significant increase in the immunity to HBV infection in the younger population aged 18 to 29 years.

Surgical Metastasectomy in AJCC Stage IV M1c Melanoma Patients with Gastrointestinal and Liver Metastases
Authors: Chua Terence C , Saxena Akshat , Morris David L
Published: January 2023

Introduction: Visceral metastases from melanoma represent the poorest prognosis based according to the revised version of the AJCC staging system that recognises both clinical and pathological features distinctive to melanoma. Given that systemic treatments in metastatic melanoma to date remains inadequate, we evaluated the efficacy of surgical metastasectomy on survival outcomes. Materials and Methods: Between year 2000 and 2009, 23 patients with visceral metastases from melanoma were evaluated for metastasectomy. Retrospective review was undertaken of the specific therapy administered following consensus meeting of a multidisciplinary team. Results: There were 16 males and 7 females. Seventeen patients (74%) had metachronous gastrointestinal/liver metastases following previous treatment of the primary tumour. The median time to development of gastrointestinal/liver metastases, otherwise known as disease-free interval, was 49 (range, 5 to 559) months. Overall median survival period was 9 months, with a 1- and 3-year survival percentages of 39% and 30%, respectively. Survival was influenced by the number of metastases (P = 0.05) and the treatment received (P = 0.03). The disease-free and overall survival periods after metastasectomy were 14 and 21 months, respectively. The 1- and 3-year survival percentages were 60% and 40%, respectively. Patients with single site of metastasis survived longer than patients with more than one site of metastasis (P= 0.005). Conclusion: Patients with visceral metastases from melanoma may derive survival benefit from metastasectomy over systemic therapy. Judicious selection of patients for metastasectomy is paramount for the success of treatment in this group of patients.

Clinical Features Differentiating Biliary Atresia from Other Causes of Neonatal Cholestasis
Authors: Lee Way Seah , Chai Pei Fan
Published: January 2023

Introduction: This study determined any clinical features which may help to differentiate biliary atresia (BA) from other causes of neonatal cholestasis (NC). Materials and Methods: A prospective and observational study was conducted on consecutive infants with NC referred to the University of Malaya Medical Centre, Malaysia, between November 1996 and May 2004. Results: The 3 most common causes of cholestasis among the 146 infants with NC studied were idiopathic neonatal hepatitis (n = 63, 43%), BA (n = 35, 24%) and congenital cytomegalovirus hepatitis (n = 13, 9%). Common clinical features at presentation were jaundice (100%), hepatomegaly (95%), splenomegaly (52%) and pale stools (47%). Three clinical features noted to be sensitive for BA were the presence of acholic or variably acholic stools on admission, a liver which was firm/hard in consistency and a palpable liver of ≥4 cm (sensitivity of 77%, 80% and 94%, respectively), but the corresponding specificity was poor (51%, 65% and 39%, respectively). The stools of 2 children with BA were pigmented initially but became acholic subsequently. Conclusions: We did not find any single clinical feature with sufficient sensitivity and specificity to differentiate BA from other causes of NC. Repeated inspection of stools colour is necessary as occasionally, patients with BA may have initial pigmented stools. Biochemical assessment and imaging studies are important in the assessment of any infant with NC.

Introduction: High workload volumes in a Cytogenetics laboratory can lead to long result turn-around times (TAT). This study aimed to improve laboratory efficiency by adopting Lean Management System initiatives to increase productivity through the elimination of wastes. This study examined if the prerequisite 20-cell analysis was sufficient for a conclusive result or if additional cell workup was necessary to ascertain the presence of a previous chromosome abnormality among cases on follow-up, or when a single abnormal cell was encountered during the analysis to determine the presence of a clone. Materials and Methods: The karyotype results of cases that had additional workup were retrieved from among 8040 bone marrow cases of various haematological disorders performed between June 2003 and June 2008. Results: Of 8040 cases analysed, 2915 cases (36.3%) had additional cell workup. Only 49 cases (1.7%) led to the establishment of a clone. The majority of these cases could have been resolved without the additional workup, especially if fluorescence in situ hybridization (FISH) or polymerase chain reaction (PCR)-based assays had been utilised. Conclusion: This study shows that the additional workup procedure is redundant. The time saved by discontinuing the workup procedure can be used to analyse other cases, leading to increased laboratory efficiency and a faster TAT without compromise to patient care. The practice of additional workup over and above the 20-cell analysis should be dispensed with as little benefit was derived for the amount of additional manpower expended. FISH or PCR-based assays should be utilised to elucidate a case further.

Published: January 2023

No presente trabalho objetiva-se investigar as estratégias discursivas que são mobilizadas por escolas de idiomas para enunciar acerca do ensino e aprendizagem de inglês para crianças. Como respaldo para o desenvolvimento deste estudo, amparamo-nos as investigações de Foucault (2008a; 2008b), Garcia (2011) e Vasconcelos e Siqueira (2021). Quanto à metodologia, trata-se de um estudo descritivo-interpretativo de natureza qualitativa. O corpus compreende materialidades discursivas que estão contidas em sites de duas escolas de idiomas: Wizard by Pearson e Fisk. A análise das propagandas permitem averiguar a existência de estratégias discursivas que defendem um aprendizado mais significativo no período da infância, concebida como uma fase cheia de descobertas e entusiasmos, e, por isso, afirmam que o ensino precisa pautar-se na diversão e interação, estimulando um aprendizado do inglês com mais facilidade.

The ability of banking organizations to maximize the resources under their control will undoubtedly be determined by the efficiency measurement. In other words, a company's productivity will increase with increased efficiency. The Data Envelopment Analysis (DEA) idea, which measures business efficiency, has evolved into the super efficiency notion.

The purpose of this study was to determine the effect of customer experience, information quality, and service innovation on repurchase intention mediated by trust in conventional taxi customers in Jakarta. Trust as mediation aims to strengthen repurchase intention to increase the desire to repurchase conventional taxi services in Jakarta. In this study, a quantitative research method was used, and the hypothesis testing of the population used in this study was conventional taxi users registered at Soekarno Hatta airport in 2021. Sampling used a purposive sampling technique and 347 respondents who were conventional taxi customers. Data analysis used software Amos version 26 with the support of multivariate analysis method structural equation model version 8.80 in hypothesis testing. The findings of this study are the direct effect of service innovation on repurchase intention is not supported. Meanwhile, the hypothesis of service innovation in forming repurchase intention is also not supported because conventional taxis already have a certain market, namely, customers aged between 40 to 55 years and are comfortable with the experience of using these conventional taxis. On the other site, another six-hypothesis direct effect are supported, and 2 indirect effects are also supported. The implications of the results of this study are for conventional taxi companies to maintain and further improve excellent service quality, especially for conventional taxi customers in Jakarta who have experienced a customer experience with convenient, flexible, and fast service.
