This article aims to measure the impact of economic growth and urbanization on poverty reduction in Vietnam, and verify whether economic growth and urbanization will help reduce poverty rates. Data for this study are tabular data related to growth, urbanization and poverty at the provincial level for the period of nine years, from 2006 to 2014 provided by the Vietnam General Statistics Office and the Vietnam General Department of Customs. The level of economic growth and urbanization mentioned in the study is reflected in such indicators as GDP value, exports value, imports value, urbanization rate and employment rate. The authors used logistic regression models with fixed-effects and logistic regression models with random effects. With 5% confidence level tested by the Chi-Square test of Hausman trial with the fixed-effect model, research results show that: (1) factors with significant negative impact on the poverty rate include imports value, urbanization rate and, employment rate; (2) factors that do not affect the poverty rate include exports value and GDP value. Based on the research results, this study proposes a number of policy recommendations to help promote economic growth, to sustain the urbanization process, and to contribute directly and positively to poverty reduction in Vietnam.

This study deals with shopping value and trust as the factors to influence consumer attitude and purchase intention in online shopping. Utilitarian and hedonic shopping values, trust, attitude and purchase intention are incorporated into the Value-Attitude-Behavior model to find out how differently shopping values and trust influence online shoppers attitude and purchase intention when they have different purchase experiences. Data are collected from survey of 187 subjects and divided into two groups according to their online purchase experiences : 97 shoppers with low online purchase experiences and 89 with high experiences. PLS(Partial Least Square) method is applied to estimate the research model and to test 7 hypotheses. The results show the difference of the way how shopping value and trust influence purchase intention. In the case of low experienced online shoppers, trust has the greatest influence purchase intention, followed by hedonic shopping value mediated by attitude. However utilitarian shopping values have a bigger impact on it for shoppers with high purchase experiences. In the latter, trust also has a significant impact on purchase intention at confidence level of 0.05. The results also provide useful implications for practitioners to build and manage their marketing strategies. Managers of online shopping mall should react to the different shopping value by shopper's experience.

Objectives: The purpose of this study was to explore how service quality in specialized hospitals influences customer loyalty under the mediating effects of customer trust and customer value. Methods: A statistical review was done based on the survey results of patients who had used a specialized hospital in Gyeonggi Province, South Korea. A total of 209 questionnaires were collected. After data collection, an empirical analysis was performed using SPSS 21.0 and AMOS 21.0 software. Results: Interaction quality (β = 0.254, p < 0.05) and result quality (β = 0.179, p < 0.05) significantly influenced customer trust, while physical environmental quality (β = 0.121, p > 0.05) did not. Customer trust (β = 0.571, p < 0.01) influenced customer value (β = 0.136, p < 0.05) and customer value influenced customer loyalty. In addition, customer confidence (β = 0.668, p < 0.05) was shown to have directly impacted customer loyalty without the mediating effect of customer value (0.078). Conclusions: The findings showed that interaction quality and resulting quality had important implications for customer loyalty. We therefore suggest compliance with appointment times, training to improve work-related skills for employees, improving customer satisfaction, and enhancing communication skills.

This study aims to examine the antecedent factors of debt policy on the influence of firm growth on firm value. There was a total of 19 companies involved accounting for 95 observational data from a population of 169 companies listed on the Kompas 100 Index of the Indonesia Stock Exchange from 2014 to 2018. The data were analyzed through descriptive statistics, classic assumption tests, multiple regression, and hypothesis testing. The results prove that the firm growth, proxied by asset growth or sales growth, did not have a significant influence on the debt policy. Further, there was no significant influence of debt policy on firm value when using debt ratio and also dividend policy as a control variable. In contrast, there was a positive and significant influence on the firm value when using debt to equity ratio proxy, both with or without using the control variable. Therefore, the debt policy was not proven as an antecedent on the influence of firm growth on firm value. This finding implies that there was a tendency for the company management to adopt the policy, which would increase the debt ratio to increase the investors' confidence in the stock market and investors neglect the company's dividend policy.

Using structural equation modeling, the study aims to investigate the causal relationship between working capital policies and working capital indicators on firm performance, including profitability and market value (SEM). The samples of 381 firms were selected from various industries listed on the Stock Exchange of Thailand (SET) from 2016 to 2020. The results showed that 1) there is an effect of working capital policies on profitability and market value; 2) there is an effect of working capital indicators on profitability and market value and 3) there is the effect of profitability on market value. From the results, it is suggested that conservative working capital investment policy (CIP) and conservative working capital financing policy (CFP) affect a company's performance in the Thailand context. In addition, shortening the cash conversion cycle (CCC) should be applied in management to increase profitability by reducing the receivables collection period (RCP) and inventory conversion period (ICP) while increasing the payables deferral period (PDP). The practical implications of the study provide the evidence that meeting the dues according to short CCC management can represent healthy liquidity in cash flow that helps gain investor confidence and the investment interest that further increases the market value.

The present study was carried out to investigate the potential acute toxicity of CKD-602 by a single intravenous dose in Sprague-Dawley rats. Ten males females were used in each test groups: a vehicle control, 34.7, 4l.7, 50.0, 60.0 and 72.0 mg/kg groups, and were given different single intravenous doses of CKD-602 to the test animals. Mortalities, clinical findings, and body weight changes were monitored for the 14-day period following the administration. At the end of l4-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. One, 1, 2, 8 and 9 cases of deaths occurred in the male dose groups of 34.7, 41.7, 50.0, 60.0 and 72.0 mg/kg, respectively, and 1, 5 and 9 cases in the female dose groups 50.0, 60.0 and 72.0 mg/kg, respectively. An increase in the incidence of clinical signs such as alopecia, skin pallor skin ulcerations, emaciation and change of fecal material was found in the both sexes of all treatment groups. A decrease or Suppression in the body weight was also observed in a dose-dependent manner. In autopsy, male and/or female rats of the treatment groups showed treatment-related gross findings such as splenomegaly, atrophy of the testis, epididymis, seminal vesicles, ovary, uterus and thymus which were dose-dependent in incidence and severity. Based on these results, it was concluded that a single intravenous injection of CKD-602 to rats caused significant toxicities in gastrointestinal, hematopoietic, and reproductive systems. The $LD_{50}$ value was 53.8 (95% confidence limit: 48.5~60.6) mg/kg for males and 60.l (95% confidence limit: 55.3~65.8) mg/kg for females. The $LD_{10}$ value was 39.9 (95% confidence limit: 3l.7~44.8) mg/kg for males and 50.3 (95% confidence limit: 40.6~54.8) mg/kg for females.

본 연구에서는 TIMSS 2007 결과 과학 영역의 학업 성취는 높지만 정의적 성취가 서로 다른 국가들을 선정하여 정의적 특성과 관련된 학생 설문 문항을 분석하였다. 또한 우리나라 과학 교사 대상 온라인 설문조사를 통해 과학 교수 학습의 특성과 정의적 성취에 대한 인식을 알아보았다. 학생 설문 분석 결과, 과학에 대한 자신감, 즐거움, 가치 인식 수준이 높은 학생의 비율은 홍콩, 싱가포르, 잉글랜드는 높고 우리나라, 대만, 일본은 그 비율이 낮게 나타났다. 실제 과학 수업의 교수 학습 특성을 보면 우리나라는 실험과 연구 활동이나 실생활 맥락에서의 과학 수업이 잘 이루어지지 않고 있었다. 과학 교사 대상 설문 결과에서 과학에 대한 자신감이 낮은 이유로 과학 내용이 어렵고 흥미롭지 않은 점과 과학 학습을 위한 절대적 시간의 부족을, 과학에 대한 흥미가 낮은 이유로 과학 내용이 어렵고 미래 자신의 진학이나 진로와 관련이 없다고 생각하는 점을 제시하였다. 또한 과학 교과의 가치 인식이 낮은 이유로 진로를 위해 과학을 잘 할 필요가 없어서나 과학이 일상생활에 도움이 되지 않는다고 여기는 점을 제시하였다.
