This study aims to evaluate the diversity of rotifers in various freshwater habitats in Da Nang City, Vietnam, and to investigate the relationship between community structure and environmental conditions. A total of 75 rotifer species belonging to 25 genera and 17 families were recorded, out of which seven species are new to Vietnam. Species from the families Brachionidae and Lecanidae are abundant (containing about 50% and 69.44%, respectively) in the total rotifer species in both lacustrine and riverine habitats. The number of rotifers recorded in the lakes (64 taxa) was much higher than those in rivers (36 taxa), and this is possibly due to the conditions in lakes being more favorable for the development of small zooplanktons. The significant influences of environmental factors (temperature, pH, turbidity, and trophic state) on the rotifer community were well-reflected in the distribution of commonly found species in lakes (p-value < 0.05). Our study results enrich the data on the diversity and the ecology of rotifers in Vietnam.

The Relationship

Little is known regarding the underlying relationship between smoking initiation and current quantity smoked during adolescence into young adulthood. It is possible that the influences of genetic and environmental factors on this relationship vary across sex and age. To investigate this further, the current study applied a common causal contingency model to data from a Virginia-based twin study to determine: (1) if the same genetic and environmental factors are contributing to smoking initiation and current quantity smoked; (2) whether the magnitude of genetic and environmental factor contributions are the same across adolescence and young adulthood; and (3) if qualitative and quantitative differences in the sources of variance between males and females exist. Study results found no qualitative or quantitative sex differences in the relationship between smoking initiation and current quantity smoked, though relative contributions of genetic and environmental factors changed across adolescence and young adulthood. More specifically, smoking initiation and current quantity smoked remain separate constructs until young adulthood, when liabilities are correlated. Smoking initiation is explained by genetic, shared, and unique environmental factors in early adolescence and by genetic and unique environmental factors in young adulthood; while current quantity smoked is explained by shared environmental and unique environmental factors until young adulthood, when genetic and unique environmental factors play a larger role.

Public health is influenced by environmental factors. The success of public health development can be seen from the Human Development Index (HDI). This research aims to analyze the relationship between environmental factors and the HDI in East Java in 2019. This research analyzed secondary data obtained from the East Java Provincial Health Office and published on the website of the Central Bureau of Statistics. Health Profile data in 2018 and the Human Development Index data in 2019 were used. This study used total sampling and selected all districts/cities in East Java (38 districts/cities). The Shapiro Wilk test (a sample of less than 50) was chosen to analyze the normality of the data and a Pearson correlation test was conducted to investigate the relationship between each variable. Based on our Pearson correlation analysis, we found several relationships between each variable. This study found that there is a relationship between access to decent drinking water and the HDI, as well as qualified latrines with the HDI, both with p-values of 0.000. Relationships were also found for healthy homes with the HDI with the p-value of 0.004, as well as qualified public places with the HDI with the p-value of 0.003. Finally, we found that there was no relationship between decent drinking water quality the HDI with a p-value of 0.821.

The education system in Indonesia is undergoing a slight change due to the Covid-19 virus outbreak. To prevent the spread of the virus, learning at higher education institutions that were initially face-to-face was shifted to online learning methods. The existence of changes in this learning system will affect the learning motivation of students which in turn will also affect learning outcomes. The purpose of this study was to determine the relationship between student learning motivation during the Covid-19 pandemic and learning outcomes at the Indragiri Midwifery Academy. This study is an analytic study with a cross-sectional approach (cross-sectional). The independent variable in this study is learning motivation and the dependent variable is learning outcomes. The sample in this study were 38 midwifery students at the Indragiri Midwifery Academy. Sampling with total sampling. Motivation data collection using questionnaires presented in the form of google foam and learning outcomes from the Student Study Results Card (KHS). The results showed that student learning motivation during the Covid-19 pandemic was in the moderate category as many as 32 people (84.2%), while learning outcomes in the poor category were 21 people (55.3%). Analysis of data using statistical test Chy Square test with data processing using SPSS 17.0 obtained p-value 0.378. Thus it can be concluded that there is no significant relationship between the learning motivation of midwifery students during the Covid-19 epidemic and learning outcomes at the Indragiri Midwifery Academy

Background: Loneliness in persons with schizophrenia have shown associate with depression and promotes suicide among persons with schizophrenia. Individual and environmental factors are also recognized as related factors. The environmental factors are lack of social scope and support. While one of the individual factors is self-efficacy. Objective: To determine the level of loneliness among persons with schizophrenia in Indonesia, and to evaluate the relationship of loneliness with sociodemographic characteristics and clinical factors, and to assess the modifying effects of self-efficacy. Methods: This study was a correlational study with 132 respondents. Correlation analyses were performed to examine the relationship between loneliness and self-efficacy using The UCLA Loneliness Scale and General Self-Efficacy Scale (GSE) questionnaire to collect the data. Results: This study found that the mean of loneliness among persons with schizophrenia score was 46.05 (SD = 7.16). There were no relationships between several sociodemographic characteristics and clinical factors to loneliness, however, there was a negative correlation between self-efficacy and loneliness among persons with schizophrenia (ρ = -0.180, p-value = 0.04). Conclusion: There was a correlation between self-efficacy and loneliness among persons with schizophrenia. Therefore, it is recommended that mental health professionals provide sources of self-efficacy to minimize loneliness in this population.

This study aims to evaluate the diversity of rotifers in psammon in the Central Coast of Vietnam. A total of 64 rotifer species belonging to 17 genera and 14 families were recorded in 10 samples collected at hygropsammon zones of freshwater lakes and ponds in Thua Thien Hue province. Lepadella cristata (Rousselet, 1893), Cephalodella tenuior (Gosse, 1886), and Lindia torulosa Dujardin, 1841 were new record to Vietnam rotifers fauna. Species from the families Lecanidae, Lepadellidae, and Trichocercidae are abundant (containing about 44%, 14%, and 12%, respectively) in the total rotifer species recorded. Psammonxenic species accounted for the largest percentage of the psammic rotifer community with 83%, followed by psammonphiles (11%) and psammonbionts (6%). Our study results enrich the data on the diversity and the ecology of rotifers in Vietnam.

The purpose of this study is to study the impact of manufacturing technology in facilitating lean manufacturers in achieving superior manufacturing performance while operating with by various challenges from external environment. The paper is based on a survey research done on lean manufacturers in Malaysia and their adoption of manufacturing technology to couple the implemented lean system in mitigating challenges. The challenges faced by lean manufacturing firms in many developing countries includes adopting the right technology, using it efficiently and continuously reviewing production technology in order to gain maximum output. Model from this empirical study is expected to contribute towards the enhancement of theory on contingency and its effect on performance. At theoretical level, the study results showed that of manufacturing technology mediate the relationship between environmental factors and performance of lean manufacturers.
