This study examined the relations between maternal personality, preschoolers' temperament, and overprotective and controlling parenting. A total of 285 mothers whose children aged from 4 to 6 years participated in this study. Mothers completed a set of questionnaires on their personalities, their children's temperament, and their overprotective and controlling parenting. Data were analyzed by regression analyses and t-test. First, maternal extraversion was negatively related to overprotective and controlling parenting, and maternal neuroticism was positively related to these parenting variables. Second, preschoolers' adaptability was negatively linked to overprotective and controlling parenting, and preschoolers' activity was positively linked to these parenting variables. Lastly, preschoolers' adaptability moderated the impact of maternal extraversion on controlling parenting. Maternal extraversion was a negative predictor of controlling parenting when preschoolers' adaptability was low. This relation was non-significant when preschoolers' adaptability was high. These results clearly indicate that both maternal personality and preschoolers' temperament play crucial roles in overprotective and controlling parenting.

Purpose: This article aims to explore the new town development paradigm against infectious diseases. The distribution of COVID-19 constricts economic activity. The high frequency of outbreaks of COVID-19 nationwide is due to neither malnutrition nor unhygienic environment. Research design, data and methodology: The research question starts with the idea that understanding the features of the outbreak of pandemic diseases could help public health authorities to better cope with upcoming risks in the future. We have employed a big data-based methodology to explore the outbreak of pandemic diseases. Also, an idiographic approach is used to describe the distribution of new towns against COVID-19. Results: The results demonstrate that the rapid spread of COVID-19 has had a strong impact on regional economies and urban development. It was found that there is a close relationship between infectious diseases outbreaks and new town development. Conclusions: The findings could be used to deal with new town development against infectious diseases better in other cities or countries as well. The distribution of COVID-19 may become an unexpected opportunity for a paradigm shift in the distribution of new town development to prevent not only an excessive concentration in Seoul, but also an imbalance between national and local development.

Nanotechnology is of great importance to molecular biology and medicine because life processes are maintained by the action of a series of molecular nanomachines in the cell machinery. Recent advances in nanoscale materials that possess emergent physical properties and molecular organization hold great promise to impact human health in the diagnostic and therapeutic arenas. In order to be effective, nanomaterials need to navigate the host biology and traffic to relevant biological structures, such as diseased or pathogenic cells. Moreover, nanoparticles intended for human administration must be designed to interact with, and ideally leverage, a living host environment. Inspired by nature, we use peptides to transfer biological trafficking properties to synthetic nanoparticles to achieve targeted delivery of payloads. In this talk, development of nanoscale materials will be presented with a particular focus on applications to three outstanding health problems: bacterial infection, cancer detection, and traumatic brain injury. A biodegradable nanoparticle carrying a peptide toxin trafficked to the bacterial surface has antimicrobial activity in a pneumonia model. Trafficking of a tumor-homing nanoprobes sensitively detects cancer via a high-contrast time-gated imaging system. A neuron-targeted nanoparticle carrying siRNA traffics to neuronal populations and silences genes in a model of traumatic brain injury. Unique combinations of material properties that can be achieved with nanomaterials provide new opportunities in translational nanomedicine. This framework for constructing nanomaterials that leverage bio-inspired molecules to traffic diagnostic and therapeutic payloads can contribute on better understanding of living systems to solve problems in human health.

Ionospheric anomaly is one of the major error sources which deteriorate the GNSS performance. In the equatorial region, effects of the ionospheric plasma bubbles are of great interest because they are pretty common phenomena, especially in the period of the high solar activity. In order to evaluate the GNSS performance under circumstance of the bubbles, an ionospheric scintillation monitor has been developed and installed in Bangkok, Thailand. Furthermore, a model simulating the ionospheric delay and scintillation due to the bubbles has been developed. Based on these developments, the effects of the simulated plasma bubbles are analyzed and their agreement with the real observation is demonstrated. An availability degradation of the GPS ground based augmentation system (GBAS) caused by the bubbles is exampled in details. Finally, an integrated GPS/INS approach based on the Doppler frequency is proposed to remedy the deterioration.

We probe 12CO J=2-1 and 13CO J=1-0 properties of a Virgo disk galaxy, NGC 4402 which is located near the cluster center. Our goal is to study the impact of intra cluster medium (ICM) on the molecular gas of a galaxy in the cluster environment. It has been believed that cluster galaxies are deficient in atomic hydrogen gas (HI gas) compared to their field counterparts and now there is much evidence that low density ISM can be easily removed by ram pressure caused by ICM wind. Meanwhile, no significant molecular gas deficiency of the cluster galaxy population has been found yet they show overall lower star formation rate than galaxies in the field, and it is still controversy whether dense ISM can be also stripped by the ICM wind or not. NGC 4402 with truncated HI disk($D_{HI}/D_{opt}$ ~ 0.75 and only 36%of HI gas compare to field galaxies of a similar size) and a disturbed gas morphology, appears to have strong ongoing ram pressure. Using high resolution 12 and 13CO data of NGC 4402 from a Sub Millimeter Array (SMA), we probe the molecular gas properties under strong ICM pressure. We discuss how its star formation activity and hence the global color of NGC4402 would be changed in the future.

This study employed high performance liquid chromatography (HPLC) coupled to an on-line $ABTS^+$ radical scavenging detection (RSD) system along with HPLC-electro spin impact/mass spectrometry (ESI/MS), to rapidly determine and identify antioxidant compounds occurring in blueberry extract. The extract was separated by HPLC, and then the radical scavenging activities of the separated compounds were evaluated by the on-line coupled $ABTS^+$-RSD system. The negative peaks of the $ABTS^+$-RSD system, which indicates the presence of antioxidant activity, were monitored by measuring the decrease in absorbance at 734 nm. The active components in the blueberry extract were identified by HPLC-ESI/MS using their MS spectra and retention times. According to the data acquired from the on-line HPLC-$ABTS^+$-based assay and HPLC-ESI/MS systems, the antioxidant compounds detected in the blueberry extract were identified as chlorogenic acid and 11 anthocyanins.

Purpose: This study sought to investigate health behavior (HB) and its affecting factors based on Anderson's behavioral model in Lao People's Democratic Republic (PDR). Also, it attempted to identify the mediation of the health locus of control (HLC) between HB and the affecting factors. Methods: Secondary data from 694 people without noncommunicable diseases (NCDs) from a survey conducted by the Ewha Womans and the Laos University were used. The measurements included predisposing, enabling, and needs factors, HLC, HB (current non-smoking, low-risk drinking, physical activity, fruit and vegetable consumption, medical checkup). The mediating effect was analyzed using Baron and Kenny's method and the Sobel test. Results: Predisposing (gender, educational level, ethnic), enabling (social support, item ownership in household) and the needs factors (body mass index) were affecting HB. Internal HLC had a positive influence on HB. The stronger the others and chance HLC, the lower the HB. Chance HLC mediated the relationship between the educational level and HB. Conclusion: There is a need to recognize the importance of chance HLC as a mediator between the educational level and HB. Through this result, high-quality nursing education for the prevention of NCDs should be developed considering the impact of chance HLC.

Bankruptcy is indicated by the inability of the company to meet its maturity obligations. The Covid-19 pandemic has had a terrible impact on the economy and businesses. The aim of this study to determine the effect of the ratios of activity, growth, leverage, and profitability in predicting bankruptcy projected by earnings per share (EPS). The sample of this research was non-banking financial sector companies listed on the Indonesia Stock Exchange in 2015-2019 and the purposive sampling technique was used. The data analysis method used was the logistic regression method to test the hypotheses. Company growth shows the company's ability to manage sales and generate high company profits, as such, the probability of the company experiencing bankruptcy will be lower. The results of this study showed that the debt to assets ratio (DAR), debt to equity ratio (DER), and return on assets (ROA) can predict bankruptcy. Meanwhile, this research found that the total assets turnover (TATO) ratio, sales growth, and net profit margin (NPM) cannot be used to predict bankruptcy.

The global population has increased with swift urbanization in developing countries, and it is likely to result in a high demand for animal-derived protein-rich foods. Animal farming has been constantly affected by various stressful conditions, which can be categorized into physical, environmental, nutritional, and biological factors. Such conditions could be exacerbated by banning on the use of antibiotics as a growth promoter together with a pandemic situation including, but not limited to, African swine fever, avian influenza, and foot-and-mouth disease. To alleviate these pervasive tension, various immunomodulants have been suggested as alternatives for antibiotics. Various studies have investigated how stressors (i.e., imbalanced nutrition, dysbiosis, and disease) could negatively affect nutritional physiology in chickens. Importantly, the immune system is critical for host protective activity against pathogens, but at the same time excessive immune responses negatively affect its productivity. Yet, comprehensive review articles addressing the impact of such stress factors on the immune system of chickens are scarce. In this review, we categorize these stressors and their effects on the immune system of chickens and attempt to provide immunomodulants which can be a solution to the aforementioned problems facing the chicken industry.

Purpose: The advantages of corporate social responsibility (CSR) include stronger recognition and reputation, which lead to a company's good public image, increased customer loyalty, operational cost saving, and employee retention. The purpose of the present research is to take a close look at the association between CSR and organization's value. Research design, data and methodology: The authors tried to obtain the high-quality textual data from mostly peer-reviewed journals using a PRISMA ((Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The authors was to figure out adequate solutions from limited range of the current literature (only peer-reviewed research) regarding CSR and corporate value. Results: Our investigation indicates that CSR is essential to all businesses as it ensures they keep in touch with society, retaining top personnel, and achieving top financial success. Companies and organizations can engage in four corporate social responsibility initiatives to increase value, including environmental projects, charitable work, honest labor practices, and volunteer activity. Conclusions: An organizations should be involved in the community and consider how its actions affect the environment and society. Small or large businesses are expected to lead in developing a progressive CSR program that benefits people and the environment and continuously changes depending on the social and economic environment.
