  • This study aimed at measuring the rural people's level of value and morality, identifying its related variables, and drawing some implications for rural adult education. To measure their value and moral levels, 141 Yoncheon county adults were interviewed or asked to answer the questionnaires based on the Braithwaite and Law's(value) and Rest's(morality) instruments. The data were analyzed mainly by ANOVA, Chi square test and Pearson product-moment correlation. The major findings were: (1) The rural people mainly remained in vital feeling value(fourth) level out of five levels(religious holiness, spiritual, mind, vital feeling and sensible feeling value in order), (2) They remained in harmonious interpersonal expectations stage(fourth mortality level) out of six stage(universal ethical principles, social contract, social conscience maintenance, harmonious interpersonal expectation, instrumental purpose, and punishment/obedience in order), (3) Religion, the number of participation in adult education, and the length of such participation were three variables related to the level of value, and age, schooling years, and the number of family wane three variable related to their morality level, and (4) The relationship between value and morality levels was not significantly identified. Rural adult education needs to be more strengthened for improving their spiritual quality of life.

  • This study investigates the impact of the use of the main local languages in Burkina Faso (Moore, Dioula, Fulfulde) on labor force participation. Using Ethnologue language data, I compute the relative language distance reduction index, after which I use a probit/logit model and instrumental variable approach to account for language use policy endogeneity. This study finds that the use of the Moore language increases the likelihood of labor force participation by 36 percent, with a strong impact on women at 59 percent, nine times higher than men, and 38.3 percent for rural individuals, five times higher than individuals living in urban areas. The Dioula language exhibits comparable trends, while Fulfulde has a negative impact on individuals. The study recommends the use of local language(s) as official language(s) to improve labor force participation. However, a bilingual approach combining local and international language(s) will be of use to account for globalization and international competitiveness. The findings here may be of use to researchers and policymakers as part of their effort to increase the labor force participation rates of women and rural individuals. Moreover, this research has significant implications with regard to the implementation of language use policies in a variety of postcolonial language contexts.

  • The paper aims to investigate the impacts of long-term savings motives on fostering household participation and contribution to savings mechanisms in rural Vietnam. The paper is organized in five parts: introduction, data description, methodology, empirical results, and conclusion. The quantitative methodology is employed and three simultaneous estimation methods, including instrumental variable model, two-step model, and Heckman model are used to test these impacts as well as the robustness of results. In each model, the paper examines the impacts of independent factors on both household participation and household contribution to savings mechanisms. Two sets of independent variables: long-term savings motives (profit-making investment, accumulation for big expenditure, providing for old age, and cost of educations) and control variables (dependency rate, number of people in household, and household wealth) are in each model. A set of dataset of 2,314 households for analysis is obtained from household survey in rural Vietnam. Robust statistical findings indicate that profit-making investment emerged to be the strongest motive fostering household participation to savings mechanisms while other long-term savings motives have little or no impact on fostering household participation to savings mechanisms. In addition, education investment encourages household contribution to savings mechanisms in rural Vietnam.

  • This study explores e-banking variables that affect client satisfaction in the Saudi Arabian banking industry spanning three dimensions: reliability, security concerns, and efficiency, which were chosen as predictors of customer satisfaction in the e-banking industry. A field survey using a self-administered questionnaire as a data collection instrument was adopted to collect the required data from a convenience sample of 250 participants of Saudi banking customers. The overall fit of the hypothesized model was tested using linear regression to find the rate of the independent factors' impact on the dependent variable. The study's findings revealed that there is a statistically significant relationship between the three dimensions and customer satisfaction in Saudi e-banking, with the largest impact being that of reliability, followed by efficiency, and finally security concerns. Also, the study found there was a significant difference in reliability which was considered more important for Saudis and there was a significant difference in efficiency, which was considered more important by males. The findings of this study suggest that these three dimensions are instrumental in e-banking customer satisfaction and that banks can gain a competitive edge by providing better services in these dimensions to sustain and develop their performance in the increasingly globalized banking industry.

  • Background and Objectives: Bilateral sequential vestibular neuritis (BSVN) is a rare condition in which an inflammation or an ischemic damage of the vestibular nerve occurs bilaterally in a sequential pattern. We described four cases of BSVN. Subjects and Methods: Every patient underwent video-head impulse test during the first and the second episode of vestibular neuritis (VN), furthermore they have been studied with radiological imaging. Results: Contralateral VN occurred after a variable period from prior event. Vestibular function recovered from the first episode in one case. The other three patients developed contralateral VN. One case was due to a bilateral VN in association with a Ramsay-Hunt syndrome, in another patient clinical records strongly suggested an ischemic etiology, whereas in two cases aetiology remained uncertain. Two patients subsequently developed a benign paroxysmal positional vertigo involving the posterior canal on the side of the latest VN (Lindsay-Hemenway syndrome). Conclusions: Instrumental vestibular assessment represents a pivotal tool to confirm the diagnosis of VN and BSVN.

  • Purpose - This research aims to provide empirical evidence that highlights the importance of imported intermediate goods in long-term economic growth. To this end, this paper develops an index that measures the productivity gains associated with a country's intermediate goods imports using highly disaggregated trade data. Design/methodology - The basic hypothesis is that countries sourcing higher-productivity (or higher-quality) inputs from developed economies derive a larger benefit from foreign R&D. To explore this hypothesis, standard cross-country growth regressions are performed using the highly disaggregated data from the United Nations (UN) Commodity Trade Statistics Database (COMTRADE). To address the endogeneity issue, I apply an instrumental variable (IV) approach. Findings - The results of this study demonstrate that the index predicts subsequent economic growth in middle- and low-income countries. This finding is consistent with previous studies that have argued that developing countries can achieve substantial productivity gains by importing intermediate inputs from developed countries. By contrast, there is no evidence of a significant association between the index and economic growth in high-income countries. Originality/value - This paper contributes to our understanding of the causal relationship between international trade and economic growth. From an economic policy perspective, the results suggest that developing countries with limited technology endowment can boost growth from input-tariff liberalization.

  • Individuals have been under more stress since the COVID-19 pandemic began than they were before the pandemic. While social support is a known stress buffer among the general population, its impact on stress among vulnerable populations, such as immigrants and those living in rural areas, has received little attention in the context of South Korea. Accordingly, we examined the relationship between different types of social support and COVID-19 stress among young adult immigrants based on where they live (rural vs. urban). We conducted a survey of 300 young adult immigrants aged 25-34 years and analyzed the results. The dependent variable was COVID-19 stress, and the independent variables were four types of social support: emotional, appraisal, instrumental, and informational. We discovered that young adult immigrants in rural areas perceived higher-level social supportin all aspects compared with those in urban areas. Furthermore, social support was not related to COVID-19 stress in urban areas, while appraisal support was positively and informational support was negatively related to COVID-19 stress in rural areas. Our findings suggest that a contextualized understanding of social support is critical to understanding COVID-related stress during the COVID-19 pandemic.

  • Purpose: The improvement of the social security system can greatly affect residents' future uncertainty, and it is important to study the relationship between public pensions and household consumption. Research design, data and methodology: Using the 2018 China Household Panel Survey (CFPS) data, the instrumental variable method is used to analyze the impact of pension insurance on urban residents' consumption. Results: The results of the study show that there are differences in the impact of three different pension insurance systems on household consumption. The pension insurance for public sector significantly boosts household consumption, and having a pension insurance for public sector can increase household consumption by 7.7%. The pension insurance for enterprise employee will reduce household consumption, but this is only significant for urban households. The pension insurance for urban and rural residents has a negative impact on household consumption. For the 16- to 39-year-old group, having a pension insurance for urban and rural residents will reduce household consumption by 5.7%. At the same time, household income, assets, scale, and education level will positively stimulate household consumption. Conclusions: The study reveals varying impacts among different pension types, highlighting the need for optimizing social security schemes to incentivize higher consumption rates.

  • 본 연구에서는 NICE 신용평가의 KIS VALUE 데이터베이스로부터 2009년도부터 2015년까지의 초기 자산규모 10억원 이상 20억원 미만인 12,028개 소규모 기업을 대상으로 기술혁신 투자 및 고용창출이 신용평가에 미치는 영향을 진단하였다. 세부적으로 51,903개 기업-연 패널 정보를 이용하여 기술혁신 투자 및 고용창출이 기업에 관한 불확실성을 증가시킬 요소로 작용할 수 있다는 측면에서의'비대칭적 정보 가설'과 대비하여, 미래 성장을 위한 적극적인 경영활동으로 기업의 경쟁 역량을 개선할 것이라는'역량 가설'을 고정효과 패널 회귀분석과 도구변수(IV: instrument variable)를 이용하여 진단하였다. 연구결과를 요약하면 다음과 같다. 첫째, 창업 후 2년 이내의 신규 창업기업은 비 창업기업보다 신용도가 1% 통계적 유의수준에서 낮다. 둘째, 소규모 기업의 기술혁신 투자는 신용도에 해당연도(t)까지만 유의한 양(+)의 영향을 미치는 것으로 나타났다. 셋째, 소규모 기업의 고용 역량은 신용도에 해당연도(t)에서 1차연도(t+1)까지 양(+)의 유의한 영향을 미치는 것으로 나타났다. 넷째, 소규모 기업의 업력은 신용도에 2차연도(t+2)까지 긍정적인 영향이 나타났으며, 종업원 1인당 매출액, 유형자산 비율 및 총자산순이익률은 신용도에 최소 3년 이상 긍정적인 영향이 지속함을 확인할 수 있었다. 이런 면에서 창업 초기기업에 대하여는 정보의 비대칭으로 인한'비대칭적 정보 가설'이 타당하고, 창업기업의 기술혁신 투자나 고용창출 노력은 신용평가 기관에'위험'보다는'역량'으로 평가되는 것으로 나타났다.
