A highly sensitive, selective and rapid method for the determination of lead based on the reaction of lead (II) with 5-(4'-chlorophenylazo)-6-hydroxypyrimidine-2,4-dione (CPAHPD) and the solid phase extraction of the Pb(II)-CPAHPD complex with Amberlite XAD-2000 was developed, in the presence of pH 5.6 buffer solution and Triton X-114 medium. CPAHPD reacts with lead to form a violet complex with a molar ratio of 2:1 (CPAHPD to lead). This complex was enriched by the solid phase extraction with Amberlite XAD-2000. An enrichment factor of 500 was obtained by elution of the complex from the resin with a minimal amount of isopentyl alcohol(0.2 mL). In isopentyl alcohol medium,the molar absorptivity of the complex is $1.13{\times}10^6L\;mol^{-1}cm^{-1}$ at 647 nm. Beer's law is obeyed in the range of $5.0-160ng\;mL^{-1}$ in the measured solution. The relative standard deviation for 10 replicate samples of $50ng\;mL^{-1}$ level is 1.26%. The detection and quantification limits reaches 1.5 and $4.7ng\;mL^{-1}$ in the original samples. The presented procedure was successfully applied for determination of lead content in real samples such as vegetables, waters, biological and soil samples with satisfactory results.

Purpose: The purpose of this study is to explore the major factors affecting the development of national identity of the Millennial Korean diasporas in the CIS countries that have rarely been explored in previous studies. In particular, this study examines how perceived identities have changed due to social, cultural, and other environmental changes and suggests policy considerations accordingly. Research design, data, and methodology: This study collected data via online survey. Factor and regression analyses were applied for data analysis. Results: The findings of this study suggest a set of factors that is different from the factors generally known to affect the diasporic identities of diasporas. The results of this study provide policy implications to help them construct identities that could more positively define their diasporic lives and relationship with homeland. Conclusions: The factors of direct experiences, such as relationship with host societies and homeland experience, exhibited strong relationship with national identity and life satisfaction of the Millennial Korean diasporas in the CIS countries. The unique characteristics of the Millennials and the long history of separation from homeland showed different results. The results of this study suggest policy considerations in regard to the Millennial diasporas in the CIS countries.

The purpose of this study was to find out what factors influence the preparation of financial statements in accordance with the International Financial Reporting Standards (IFRS) for Vietnamese businesses. The survey included 150 enterprises, including parent companies of state-owned economic groups, parent companies that are listed companies, large-scale public companies that are unlisted parent companies, and enterprises with 100 percent foreign direct investment, that will apply IFRS voluntarily from the year 2022 and switch to the mandatory application from the year 2025 (Ministry of Finance, 2016). The survey was carried out with the help of the Google Form tool, and the data was processed using EFA and regression analysis methods on the SPSS 22.0 software. The findings show, for enterprises in Vietnam, that six factors influence the preparation of financial statements in accordance with IFRS, ranked in order of influence from high to low: (i) Related party requirements; (ii) Professional qualifications of accountants; (iii) Roles of enterprise managers; (iv) Forms of capital ownership in enterprises, (v) Institutional regulations, and (vi) Operational characteristics of the enterprise. In addition, the study also shows that, for enterprises in Vietnam, the requirements of related parties are an important factor to promote the preparation of the financial statements of enterprises according to IFRS.

In this paper, we investigates the benefits of using social media on intentions and implementation entrepreneurial. This study took place in a well-known vocational college in Bandung, Indonesia, from July 2020 to January 2021. The research method used was the explanatory survey. Research data obtained from 317 respondent. Factor analysis and multiple regression were used to analyze the data. According to this study, social media has three dimensions: ease of use, controllability, usability, and profit. Entrepreneurial intention is made up of two components: entrepreneurial motive and entrepreneurial effort. Furthermore, there are four components to entrepreneurship implementation: investment courage, technology tools, social media skills, and environmental support. Other findings of each dimension of social media proved to affect entrepreneurial intention positively. The four aspects of entrepreneurial execution were likewise positively influenced by the dimension of entrepreneurial intention. This research reveals that students make the most use of the technologies available on social media for business and interactively communicate with their customers. Therefore, social media plays a role in accelerating the growth of entrepreneurship among students. However, more research is needed to see if there is a continuous pattern in the findings of this study so that the findings can be generalized.

Objectives: This study aims to examine factors affecting depression of adolescents by using the data of the 17th Korean Youth Health Risk Behavior Survey(2020). Methods: The total sample was 54,848 students who are in middle or high school. In this study, sociodemographic variables, health behavior variables, and stress were input to examine the effect on depression. The data was analyzed with χ²-test and hierarchical regression by SPSS statistic program. Results: The results showed that depression was related to sociodemographic factors, health behaviors, and stress factors. In the result of hierarchical regression analysis, it was found that not only stress but also other variables had an effect on depression, which had a statistically significant effect. Conclusions: It was found that there are various causes such as environmental aspects and health behaviors that surround adolescents' depression rather than a single factor such as stress. Also, stress and depression are reciprocal rather than causal. Adolescents should be subdivided into groups such as grade, gender, or academic performance to relieve stress and depression at the same time through specific interventions.

Species diversity is one of the most important specifications of biological societies. Diversity of organisms, measurement of variety and examination of those hypotheses that are about reasons of diversity are such as affairs that have been desired by the ecologists for a long time. In this research, diversity of plant species in forest region, numbers of 60 sample plots in 256.00 square meters have been considered in random - systematic inventory was considered. In each sample plot, four micro-plots in 2.25 square meters in order to study on herbal cover, were executed that totally 240 micro-plots were considered. At each plot six diversity indices in relation to physiographic factors (slope, geographical aspect and altitude from the sea level) were studied. The results indicate that species diversity is more in the northern direction and also species diversity in slops less than 30% has the most amounts. Factor of altitude from the sea level did not have meaningful relation with species diversity. Through study on correlation of the numbers of species in sample plots with indices and also process and role of indices in different processors of analysis, Simpson's reciprocal index was suggested as suitable index in this type of studies.

Purpose: This pilot study aims to conceptualize a new green marketing mix for retail consumers based on Stimulus-Organism-Response (SOR) model. Moreover, it also aims to conceptualize a testable research model of new green marketing mix with consumers' green purchasing behavior, and to validate the measurement model with traditional as well as modern suggested validating techniques. Research design, data and methodology: A pilot test data from 75 respondents of retail buyers of energy-efficient electric appliances in Pakistan were tested for the confirmatory factor analysis (CFA) by examining a measurement model of the construct through different validation techniques (like Composite Reliability, McDonald's Omega (ω), rho (ρA), HTMT, etc.) as heretofore these scales were not validated through these modern methods. Results: The results revealed that the instrument has a certain degree of reliability and validity through different validating techniques. All the measurement items reach the suggested threshold values. Conclusions: Therefore, this study conceptualized an integrated framework of all the three stakeholders of the environment (government, companies, and public or consumers) to achieve environmental sustainability. Hence, future studies can extend these findings and conduct a full-scale study to establish an empirical relationship between the 5G's of green marketing for retailing businesses and consumers' green purchase behavior.
