The Impact of Off-Farm Income on Food Expenditure

( Hyunjeong Joo ) 한국농업경제학회 2017 農業經濟硏究 Vol.58 No.3

South Korean agriculture has been based on small, labor intensive and owner-operated farms, and the agricultural market is considered to be vulnerable to the opening of global trade led by large-scale producers under new WTO rules. Smallholder farm households, which are very common in South Korea, usually maintain a portfolio of income sources, with off-farm income being a major component. Off-farm income affects the availability of cash to make on-farm investments (land, fertilizers and pesticide, and farm equipment), family living expenses―food security, and adoption of appropriate technologies. Using farm household level data from three surveys, this study assesses the impact of off-farm income on food consumption expenditures by South Korean farm households. Results suggest that by receiving off-farm income―or engaging in off-farm work―their food consumption expenditures increase by 0.07%. Furthermore, public subsidies received by farm households are used to increase food consumption. Findings here also suggest that both farm and off-farm incomes can contribute to better food security.

Impact of Off-Farm Income and Government Subsidy on Farmland Value in South Korea

( Hyunjeong Joo ) 한국농업경제학회 2016 農業經濟硏究 Vol.57 No.4

Off-farm income and government payments are the main income resources for farm households, as they provide farm households with management security. Increased income from off-farm work or government subsidies can be capitalized in farm assets such as farmland. A plethora of literature has investigated the impact of off-farm income and government subsidies on farmland values. However, these studies are mainly concentrated in North America and Western European countries. The goal of this paper is to study the impact of off-farm income and government subsidies on farmland values in South Korea using the unconditional quantile regression. The results show that off-farm income and government payments have positive and significant effects on farmland values; this effect is higher in the upper quantiles. For instance, a 100% increase in off-farm income increased farmland values by 21% in the 90^th quantile, and a 100% increase in government subsidies increased farmland values by 10% in the 75^th quantile. This implies that the increased income from off-farm work and government subsidies have contributed to higher farmland values. When comparing off-farm income and government subsidies, off-farm income had a greater impact on improving farmland values. After analysis, a graph displayed a comparison of the coefficients among the two models: OLS with robust standard error and unconditional quantile regression. In the graph, the differences of coefficients among the model were represented, and the distinctions between the coefficients of two estimates are considerable. Results from this study can assist policymakers in many countries as they design agricultural policies to encourage growth in the non-farm economy.

예산의 성과계획서에서 성과지표의 적정성 검토 및 개선방안 연구 - 2020년 제주특별자치도 농업부문 성과지표를 중심으로-

주현정(Hyunjeong Joo) 한국콘텐츠학회 2020 한국콘텐츠학회논문지 Vol.20 No.9

예산의 성과계획서는 예산과 성과를 연계하고 성과 중심적인 정책 수행을 위하여 도입되었다. 본 연구는 성과지표가 사업부서별로 어떻게 계획되고 달성되는지 알아보기 위하여 제주특별자치도의 2020년도 농업 분야 예산의 성과계획서를 대상으로 성과지표의 적정성에 대해 검토하였다. 분석결과 정책사업과 목표 간 낮은 연계성, 성과지표에 대한 가중치와 목표치에 대한 근거 불명확, 성과지표의 낮은 도전성 등의 문제점이 있었으며, 다수의 성과지표가 실적 중심의 산출지표였다. 이러한 문제점을 개선하기 위해서는 도전적인 성과지표와 인센티브를 통한 실질적인 성과지표 구축이 필요하다. The performance plan of the budget was introduced to link the budget with the performance and to implement performance-oriented policies. This study reviewed the adequacy of indicators of the 2020 agricultural sector budget performance plan to find out how performance indicators were planned and achieved. As a result, there were problems such as low linkage between policy projects and targets, weighting of performance indicators and unclear grounds for targets, and underwhelming performance indicators. To improve these problems, challenging performance indicators and the establishment of practical performance indicators through incentives is necessary.

주현정 ( Hyunjeong Joo ),임상수 ( Sangsoo Lim ) 한국재정정책학회 2021 財政政策論集 Vol.23 No.2

본 연구는 1단계 재정분권 시행이 지방정부의 세입과 세출에 어떠한 영향을 미치고 지방자치 단체 간 재정형평성에 미친 영향을 살펴보기 위해 지니계수의 변화를 격차감소효과와 순위변동효과로 구분하는 분해 방법을 활용하여 분석했다. 결론적으로 2019년 지방소비세 확대는 지방자치단체의 세입과 세출 형평성을 개선시킨 것으로 나타났다. 구체적으로 세입의 형평성 측면에서 광역자치단체의 경우에는 지방세, 자체세입, 자주재원의 형평성이 개선된 것으로 나타났다. 기초자치단체의 경우에는 시, 군, 자치구의 자주재원과 세입 형평성이 개선된 것으로 나타났다. 세출의 형평성 측면에서 지니계수 분해법을 분석한 결과, 광역자치단체, 시, 군, 자치구의 형평성은 모두 개선되었다. 특히 광역자치단체는 격차 감소 효과에 의해 세출 형평성이 개선되었고, 시는 격차 감소 효과와 순위 변동 효과 모두에 의해 세출 형평성이 개선되었다. 본 연구는 재정분권 2단계의 구체적인 내용을 설정하고 있는 시점에서 1단계 재정분권 방안에 따른 재정 변화와 그로 인한 형평성을 세입과 세출로 구분하여 분석한다는 점에서 의의가 있다. In this study, the Gini coefficient decomposition method was used to examine how the implementation of the first phase of fiscal decentralization affects the revenue and expenditure of local governments. In conclusion, the expansion of the local consumption tax in 2019 was found to have improved the income and expenditure equity of local governments, and at the same time, it also strengthened fiscal decentralization improving the efficiency of resource allocation and fiscal equity. Specifically, in the revenue sector, the equity of local taxes and self-taxes was improved in Si, Do, while the equity of self-governing resources was improved in Gun, Gu. In the expenditure sector, although the level of equity differed depending on the Si, Do, Gun, and Gu, the level of equity was generally improved. This study is meaningful in that it analyzes financial changes and resulting equity according to the first stage of fiscal decentralization by dividing them into revenue and expenditure at a time when the details of the second stage of fiscal decentralization are being established.

Intratumoral hypoxia has been correlated with distant metastatic potential. Two hypoxia inducible factors (HIFs). HIF-1α and HIF-2α, are induced by hypoxia, and high expression of these proteins has been correlated to angiogenesis and distant metastasis. Thymosin β4 (Tβ4) is frequently highly expressed in cancer, and this overexpression correlates with malignant progression. The objective of this study was to investigate the clinical correlation of HIF-α with Tβ4 and the intracellular functional roles of Tβ4 on HIF-α activation. We examined HIF-1α, HlF-2α and Tβ4 expressions in clinical human breast carcinoma (n=70) by immunohisto-chemistry. We show that high expression of HIF-1α and HIF-2α strongly correlates with Tβ4 expression (P≤0.0001) and overexpression of Tβ4 correlates significantly with patients with lymph node metastasis (P<0.05) of human breast cancer. Additionally, we demonstrate that hypoxia up-regulates intracellular Tβ4 protein, which then affects HIF-α activity, which is the key in regulating VEGF expression. We confirmed that hypoxia-induced intracellular Tβ4 and HIF-α activities were reduced by interference of TIM expression using Tβ4 shRNA lentivirus. Vascular epidermal growth factor (VEGF)-A, a well-recognized lymphangiogenic cytokine, was also down-regulated, but VEGF-C and VEGF-D expressions were not affected. These findings suggest that the overexpression of Tβ4 is strongly associated with HIF-1α and HIF-2α expression and is also clinicopathologically involved with lymph node metastatic potential of breast cancer through the modulation of HIF-a activation and induction of VEGF-A. Ultimately, these results highlight Tβ4 as a potentially therapeutic target in malignant cancers.

프라이버시 염려가 SNS 지속사용의도에 미치는 영향: 신뢰도의 매개 및 지각된 유용성의 조절효과

이주영 ( Joo Young Lee ),강현정 ( Hyunjeong Kang ) 한국지식경영학회 2015 지식경영연구 Vol.16 No.4

Present study investigates the impact of privacy concerns of SNS users on continued intention to use since the privacy infringement issue emerges when smartphone use has been increasingly prevalent. In particular, moderating effect of perceived usefulness and mediating effect of trust between privacy concerns and contined intention to use are further evaluated. Contrary to the expectation that users of SNS will resist to use SNS because of privacy concerns, the number of users of SNS is still growing exponentially. Current paradox might be explained by the intervening factors such as perceived usefulness and trust. The results verify the mediating role of trust and no moderating role of perceived usefulness. Finally, the practical implication for busiensses who utilize SNS in their marketing strategy is discussed.

Health-Related Quality of Life During the Menopausal Transition: Testing a Theoretical Model

Shin, Hyunjeong,Park, Young-Joo Springer Publications 2016 Research and theory for nursing practice Vol.30 No.2

<P>The purpose of this study was to test the hypothetical model of health-related quality of life (HRQOL) during the menopausal transition. The model was developed to test specific components of the Wilson and Cleary’s model for HRQOL. A cross-sectional, correlational study was carried out using self-report questionnaires on a convenience sample of 162 Korean women in the menopausal transition. The model was tested by a path analysis using Analysis of Moment Structure (AMOS) program. The path analysis showed that 5 affecting variables explained 69% of the variance in HRQOL during the menopausal transition. Based on the results, the Wilson and Cleary’s model may be useful in explaining HRQOL during the menopausal transition. Symptoms, functional status, and health perceptions mediated the effect of individual and environmental characteristics on HRQOL. However, the results suggest that some paths need to be added or modified in the model. To date, most research using Wilson and Cleary’s model has been conducted in the United States, Africa, and Europe (e.g., Austria, Norway, and Spain). This study shows the applicability of the model in Asian people.</P>
