These forests, called sacred forest or ghost forests by the ethnic minority people in Thua Thien Hue province, have existed for a long time among forest residents. However, they have recently declined, both in quality and quantity, due to various factors, including changes in society, economy, environment, and perception, among other reasons. Based on research conducted in A Luoi district, Thua Thien Hue province with household interviews, group discussions, and field surveys, we find that spiritual forest retains religious and human significance. They are also often among the last remaining natural forests left due to deforestation by human activities. The research results indicate challenges that conservation of spiritual forest may face, while giving recommendations derived from communities for sustainable forest development and conservation in the region.展开更多

This disease is also an important public health problem. Clinical manifestations can be classified as cutaneous, mucocutaneous, and visceral leishmaniasis, depending on the species of parasite and the host’s immune status. Although the cutaneous form is not fatal, it often causes disfiguring scars on the skin[1].展开更多

Rape can be perpetrated with or without physical restraint. The objective of the present study is to highlight the prevalence of physical coercion leading to pregnancy and the associated maternal-fetal complications. Methodology: This was a comparative descriptive and analytical cross-sectional study of complications associated with post-rape pregnancy by physical restraint among minors who were treated at the General Reference Hospital of Panzi over a two-year period from June 2020 to June 2022. A total of 140 minor survivors of violence with pregnancy were included in the study. Data were collected using a questionnaire, coded and analyzed in Excel and XLSTAT version 2014. Results: The prevalence of physical constraints was 65%. After mulltivariate analyses, denial of pregnancy (ORa: 9.64 95% CI: 1.1 - 81.2;p-value: 0.0370), attempted abortion (ORa: 56.1 95% CI: 1.5 - 2027.6;p-value: 0.0278) and agitation during delivery (ORa: 88.7 95% CI: 4.5 - 1715;p-value: 0.0030) were the complications associated with pregnancy in minors who experienced physical restraint rape. In addition, BMI was a factor in reducing the risk of physical restraint rape at the ORa of 0.5054 [0.3;0.8];p 0.006). Conclusion: Pregnancy among minors is a reality and occurs in a situation of physical coercion in the eastern Democratic Republic of Congo. These pregnancies are often associated with complications that require an intensive management system since they can jeopardize the maternal-fetal prognosis of minors.展开更多

Nowadays, there is still no consensus on a single portrait of child sex offenders and studies that focus on sex offenders are still rare in Senegal and Africa. Objectives: To determine the profile of the perpetrators and to identify the circumstances of sexual violence against minors in Casamance. Materials and Methods: A retrospective descriptive and analytical study from April 1, 2014 to October 31, 2019 was conducted. The study population was made up of perpetrators of sexual violence against minors whose legal proceedings were dealt with at the Ziguinchor High Court. The data were entered into an Excel spreadsheet and then analyzed using Epi Info<sup>TM</sup> 7 software. Results: A total of 106 cases of sexual violence against minors were collected for 113 aggressors and 106 victims. Rape accounted for 66.03% of sexual violence. Male aggressors were 98.23%. Female victims accounted for 95.28%. The average age of the attackers was 32.52 years (±13.68). Offenders over the age of 35 committed the most rape (p = 0.043). The average age of the victims was 12.62 years (±3.42). Victims aged ten and over (p = 0.015) and who had a low level of education (p = 0.016) were more exposed to rape. The assault took place during the day (65.71%) and at the home of the aggressor (62.26%). Victims knew their attackers (84.47%). Victims were assaulted more than once by the same assailant (40.57%). Those aged 10 years and over (p = 0.0037) and who knew their attackers (p = 0.014) were more at risk of being repeatedly sexually abused. Conclusion: In Senegal, sexual violence against minors is perpetrated by young adult men, single, with little or no education and exercising low-income professions. Rape is the type of aggression preferred by perpetrators, most of whom were known to their victims. The policy to fight sexual violence against children must integrate sex education at school and community level, public awareness, monitoring of child sex offenders and possibly, their medico-psychological care.展开更多

Among these are various ethnic folk chess games. They are time-honored with many types such as the “Fang” chess of the Hui ethnic group, the “Jiu” chess of the Tibetans, the “King and Ministers” chess, the Mongolian chess, the Mongolian military chess, etc. These games embody distinctive ethnic and regional characteristics, as well as the cultural elements of a particular ethnic minority group. It is of great significance, therefore, to study the ethnic chess by collecting, documenting and comparing different types of related chess. The paper explores ways to standardize, protect and promote them scientifically in joint efforts, and draws a conclusion that examining their significance in the present era and the ethnic characteristics is the key to understanding the profound culture behind the chess.展开更多

A colossal amount of effort has been taken to reduce new HIV infections, but there are still a significant number of new infections reported. HIV prevalence is more skewed towards the key population who include female sex workers (FSW), men who have sex with men (MSM), and people who inject drugs (PWID). The study design was retrospective and focused on key population enrolled in a comprehensive HIV and AIDS programme by the Kenya Red Cross Society from July 2019 to June 2021. Individuals who were either lost to follow up, defaulted (dropped out, transferred out, or relocated) or died were classified as attrition;while those who were active and alive by the end of the study were classified as retention. The study used density analysis to determine the spatial differences of key population attrition in the 19 targeted counties, and used Kilifi county as an example to map attrition cases in smaller administrative areas (sub-county level). The study used synthetic minority oversampling technique-nominal continuous (SMOTE-NC) to balance the datasets since the cases of attrition were much less than retention. The random survival forests model was then fitted to the balanced dataset. The model correctly identified attrition cases using the predicted ensemble mortality and their survival time using the estimated Kaplan-Meier survival function. The predictive performance of the model was strong and way better than random chance with concordance indices greater than 0.75.展开更多

文摘BACKGROUND Postoperative delirium,particularly prevalent in elderly patients after abdominal cancer surgery,presents significant challenges in clinical management.AIM To develop a synthetic minority oversampling technique(SMOTE)-based model for predicting postoperative delirium in elderly abdominal cancer patients.METHODS In this retrospective cohort study,we analyzed data from 611 elderly patients who underwent abdominal malignant tumor surgery at our hospital between September 2020 and October 2022.The incidence of postoperative delirium was recorded for 7 d post-surgery.Patients were divided into delirium and non-delirium groups based on the occurrence of postoperative delirium or not.A multivariate logistic regression model was used to identify risk factors and develop a predictive model for postoperative delirium.The SMOTE technique was applied to enhance the model by oversampling the delirium cases.The model’s predictive accuracy was then validated.RESULTS In our study involving 611 elderly patients with abdominal malignant tumors,multivariate logistic regression analysis identified significant risk factors for postoperative delirium.These included the Charlson comorbidity index,American Society of Anesthesiologists classification,history of cerebrovascular disease,surgical duration,perioperative blood transfusion,and postoperative pain score.The incidence rate of postoperative delirium in our study was 22.91%.The original predictive model(P1)exhibited an area under the receiver operating characteristic curve of 0.862.In comparison,the SMOTE-based logistic early warning model(P2),which utilized the SMOTE oversampling algorithm,showed a slightly lower but comparable area under the curve of 0.856,suggesting no significant difference in performance between the two predictive approaches.CONCLUSION This study confirms that the SMOTE-enhanced predictive model for postoperative delirium in elderly abdominal tumor patients shows performance equivalent to that of traditional methods,effectively addressing data imbalance.
文摘This editorial is intended to be a reflection on cardiovascular disease(CVD)burden in European ethnic minorities.In some European countries,ethnic minority realities,due to their recent appearance,are still to be studied in depth.The experience of several European countries,where the migration processes started earlier,even more than a century ago,can help by being an example.Many studies have shown that major differences in CVD burden exist not only between countries,but also within the same country when considering different social strata and ethnic groups.The CV risk factors underlying heart disease have been well established.Important epidemiological studies have helped us understand that the underlying causes of heart disease as well as the behaviors that can help prevent them are the same.We are now well aware that CVD should be treated by considering a holistic approach.This is why the social determinants(SDs)of health that may worsen the disease burden or that,vice versa,may improve the treatment,and even more significantly,the prognosis of a patient’s illness should be taken into consideration.For ethnic minority patients,this holistic,hermeneutic approach is of importance.Several SDs of health that influence CVDs have been identified but their relevance for the health of ethnic minorities has not yet been clearly defined.In some European countries,most ethnic minorities are largely also religious minorities.Only a few studies have evaluated the role of religion,which is an important SD that affects the probability of having CV risk factors and diseases.Adolescents,particularly those belonging to the second generation,seem to be the weak link.If we believe that these young people are really citizens of their country of birth,then a way of recognizing their belonging to the community starts from a will to better understand their condition,in order to assist them while they grow physically and mentally.Thinking about safeguarding the health of this population should be more than a health task,rather a goal of social justice.
文摘This paper aims to analyze and evaluate a model of forest conservation and management of ethnic minority (or indigenous) people in central Vietnam, often referred to as the spiritual forest. These forests, called sacred forest or ghost forests by the ethnic minority people in Thua Thien Hue province, have existed for a long time among forest residents. However, they have recently declined, both in quality and quantity, due to various factors, including changes in society, economy, environment, and perception, among other reasons. Based on research conducted in A Luoi district, Thua Thien Hue province with household interviews, group discussions, and field surveys, we find that spiritual forest retains religious and human significance. They are also often among the last remaining natural forests left due to deforestation by human activities. The research results indicate challenges that conservation of spiritual forest may face, while giving recommendations derived from communities for sustainable forest development and conservation in the region.

文摘Introduction: Pregnancy resulting from rape is a public health and sexual and reproductive health issue, especially among minors. Rape can be perpetrated with or without physical restraint. The objective of the present study is to highlight the prevalence of physical coercion leading to pregnancy and the associated maternal-fetal complications. Methodology: This was a comparative descriptive and analytical cross-sectional study of complications associated with post-rape pregnancy by physical restraint among minors who were treated at the General Reference Hospital of Panzi over a two-year period from June 2020 to June 2022. A total of 140 minor survivors of violence with pregnancy were included in the study. Data were collected using a questionnaire, coded and analyzed in Excel and XLSTAT version 2014. Results: The prevalence of physical constraints was 65%. After mulltivariate analyses, denial of pregnancy (ORa: 9.64 95% CI: 1.1 - 81.2;p-value: 0.0370), attempted abortion (ORa: 56.1 95% CI: 1.5 - 2027.6;p-value: 0.0278) and agitation during delivery (ORa: 88.7 95% CI: 4.5 - 1715;p-value: 0.0030) were the complications associated with pregnancy in minors who experienced physical restraint rape. In addition, BMI was a factor in reducing the risk of physical restraint rape at the ORa of 0.5054 [0.3;0.8];p 0.006). Conclusion: Pregnancy among minors is a reality and occurs in a situation of physical coercion in the eastern Democratic Republic of Congo. These pregnancies are often associated with complications that require an intensive management system since they can jeopardize the maternal-fetal prognosis of minors.
文摘Introduction: The causes of sexual delinquency against children are multifactorial and the motivations that drive the perpetrators of sexual assault are diverse. Nowadays, there is still no consensus on a single portrait of child sex offenders and studies that focus on sex offenders are still rare in Senegal and Africa. Objectives: To determine the profile of the perpetrators and to identify the circumstances of sexual violence against minors in Casamance. Materials and Methods: A retrospective descriptive and analytical study from April 1, 2014 to October 31, 2019 was conducted. The study population was made up of perpetrators of sexual violence against minors whose legal proceedings were dealt with at the Ziguinchor High Court. The data were entered into an Excel spreadsheet and then analyzed using Epi Info<sup>TM</sup> 7 software. Results: A total of 106 cases of sexual violence against minors were collected for 113 aggressors and 106 victims. Rape accounted for 66.03% of sexual violence. Male aggressors were 98.23%. Female victims accounted for 95.28%. The average age of the attackers was 32.52 years (±13.68). Offenders over the age of 35 committed the most rape (p = 0.043). The average age of the victims was 12.62 years (±3.42). Victims aged ten and over (p = 0.015) and who had a low level of education (p = 0.016) were more exposed to rape. The assault took place during the day (65.71%) and at the home of the aggressor (62.26%). Victims knew their attackers (84.47%). Victims were assaulted more than once by the same assailant (40.57%). Those aged 10 years and over (p = 0.0037) and who knew their attackers (p = 0.014) were more at risk of being repeatedly sexually abused. Conclusion: In Senegal, sexual violence against minors is perpetrated by young adult men, single, with little or no education and exercising low-income professions. Rape is the type of aggression preferred by perpetrators, most of whom were known to their victims. The policy to fight sexual violence against children must integrate sex education at school and community level, public awareness, monitoring of child sex offenders and possibly, their medico-psychological care.

文摘The attention-based encoder-decoder technique,known as the trans-former,is used to enhance the performance of end-to-end automatic speech recognition(ASR).This research focuses on applying ASR end-toend transformer-based models for the Arabic language,as the researchers’community pays little attention to it.The Muslims Holy Qur’an book is written using Arabic diacritized text.In this paper,an end-to-end transformer model to building a robust Qur’an vs.recognition is proposed.The acoustic model was built using the transformer-based model as deep learning by the PyTorch framework.A multi-head attention mechanism is utilized to represent the encoder and decoder in the acoustic model.AMel filter bank is used for feature extraction.To build a language model(LM),the Recurrent Neural Network(RNN)and Long short-term memory(LSTM)were used to train an n-gram word-based LM.As a part of this research,a new dataset of Qur’an verses and their associated transcripts were collected and processed for training and evaluating the proposed model,consisting of 10 h of.wav recitations performed by 60 reciters.The experimental results showed that the proposed end-to-end transformer-based model achieved a significant low character error rate(CER)of 1.98%and a word error rate(WER)of 6.16%.We have achieved state-of-the-art end-to-end transformer-based recognition for Qur’an reciters.
文摘Whether,and how,to rescind the right of one party(the non-breaching party)to rescind a contract in case of an obviously minor breach by the other party(the breaching party)is a recurring topic in the field of contract law.The Minutes of the Ninth Work Conference of the Courts Nationwide on Civil and Commercial Trial(the Minutes of the Ninth Work Conference)stipulates that whether a contract shall be rescinded depends on whether a breach is obviously minor and affects the fulfillment of the contract purposes expected by the non-breaching party.In juridical practice,however,there are no clear criteria to define what constitutes obviously minor breaches,and the factors considered in such cases are often inadequate to allow for a fully considered decision.By analyzing Article 55 of the Judicial Interpretation of the General Provisions of Contracts of the Civil Code of the People’s Republic of China(Draft for Comments)and reviewing the previous juridical practices,we present our conclusions regarding the conditions and factors that should be considered when restricting the right of rescission in cases of obviously minor breaches with a view to unifying the judicial judgment criteria by differentiating the type of breaches.

文摘Low fertility and population aging are important factors affecting economic and social development.From 2000 to 2020,the development of low fertility in ethnic minority areas shows three trends of accelerated declining,slow declining and first falling and then rising,which are the results of the balance between the inhibiting effect of controlling birth policy and the rapidly rising birth cost,and the promoting effect of encouraging birth policy on the fertility desire of social members.The development of aging in ethnic minority areas shows two trends of acceleration and deceleration,which are the results of the balance between the promoting effect of controlling birth policy,the outflow of young and middle-aged labor force and the rise of life expectancy,and the inhibiting effect of the encouraging birth policy,the restraint of talent return and talent introduction.Combined with the development degree of low fertility and aging,we can accurately classify and implement policies for different ethnic minority areas.The areas with serious low fertility and population aging problems need economic policies to change the population age structure as soon as possible.The areas with slight low fertility and population aging problems should carry out ideological policies in priority to maintain the benign structure of population age.
文摘The traditional musical instrument of minorities converges the evolution of ethnic group culture and history,and ethnic musical instruments are a core component of minority culture.The traditional instruments of Guangxi minorities are rich and varied,and an all-round cultural inheritance and protection mechanism should be used for ethnic musical instruments,so that the performance form of classical musical instruments of minorities can be more widely understood and mastered.Therefore,in this paper,we discuss the specific practice idea of the inheritance and development of classical musical instruments of Guangxi minorities,and facilitate the innovation of development path of ethnic musical instruments by taking the inheritance form of integrating musical instruments with operas.

文摘The right of minors to express their opinions in family litigations refers to minors,who have a certain degree of mental capacity and assertiveness,having the right to express their opinions on the arrangements or decisions related to themselves when the courts handle familial litigation cases involving their interests,and to request the courts hear their opinions.In essence,the right of minors to express their opinions in family litigations belongs to the basic procedural rights of minors as well as judicial beneficiary rights.As for the protection of the right of minors to express their opinions in family litigations,recognizing the status of minors as independent subjects of rights is the logical premise,the procedural guarantee for the rights of the substantive parties involved is the direct cause,and ensuring the best interests of children is the fundamental reason.In order to protect the right of minors to express their opinions in family litigations,China should standardize the mechanisms for judges to hear the opinions of minors directly,improve the mechanisms for family investigators,and establish mechanisms for representing the interests of minors.
文摘As a region inhabited by large populations of ethnic minority groups, Gansu province boasts rich ethnic cultural resources which reflect traditional culture and intangible cultural heritage that had taken shape thousands of years ago. Among these are various ethnic folk chess games. They are time-honored with many types such as the “Fang” chess of the Hui ethnic group, the “Jiu” chess of the Tibetans, the “King and Ministers” chess, the Mongolian chess, the Mongolian military chess, etc. These games embody distinctive ethnic and regional characteristics, as well as the cultural elements of a particular ethnic minority group. It is of great significance, therefore, to study the ethnic chess by collecting, documenting and comparing different types of related chess. The paper explores ways to standardize, protect and promote them scientifically in joint efforts, and draws a conclusion that examining their significance in the present era and the ethnic characteristics is the key to understanding the profound culture behind the chess.
文摘HIV and AIDS has continued to be a major public health concern, and hence one of the epidemics that the world resolved to end by 2030 as highlighted in sustainable development goals (SDGs). A colossal amount of effort has been taken to reduce new HIV infections, but there are still a significant number of new infections reported. HIV prevalence is more skewed towards the key population who include female sex workers (FSW), men who have sex with men (MSM), and people who inject drugs (PWID). The study design was retrospective and focused on key population enrolled in a comprehensive HIV and AIDS programme by the Kenya Red Cross Society from July 2019 to June 2021. Individuals who were either lost to follow up, defaulted (dropped out, transferred out, or relocated) or died were classified as attrition;while those who were active and alive by the end of the study were classified as retention. The study used density analysis to determine the spatial differences of key population attrition in the 19 targeted counties, and used Kilifi county as an example to map attrition cases in smaller administrative areas (sub-county level). The study used synthetic minority oversampling technique-nominal continuous (SMOTE-NC) to balance the datasets since the cases of attrition were much less than retention. The random survival forests model was then fitted to the balanced dataset. The model correctly identified attrition cases using the predicted ensemble mortality and their survival time using the estimated Kaplan-Meier survival function. The predictive performance of the model was strong and way better than random chance with concordance indices greater than 0.75.

文摘Gaokao has been considered as the gatekeeper of intergenerational class reproduction in today’s slowing social mobility in China.In order to bolster the fairness of Gaokao,the Policy of Bonus Scores for Ethnic Minority Candidates(PBSEMC)has been issued,whose,however,effectiveness in promoting upward social class has not been adequately empirically explored.The difference-in-differences(DID)analysis based on cross-sectional data,which is distinct from the traditional DID analysis paradigm,was implemented to assess the Reform of PBSEMC in the Guangxi Zhuang Autonomous Region in 1988.The results showed that PBSEMC had a significant and positive impact on the social classes of ethnic minorities,and gender,residence type and occupation type were also relevant to social class,aligning with the previous literature.The PBSEMC is effective in improving the social classes of ethnic minorities.However,the PBSEMC policy should be made more precise,in order to benefit the candidates who are in genuine need of assistance.
