We pursue empirically influential determinants of risk-sharing across various groups in the United States. We consider all the possible combinations out of the eight BEA economic regions and relate the risk-sharing measure for each group to sectoral composition difference under the control of the state-level macroeconomic and financial characteristics. Our results show that more active risk-sharing via cross-ownership market is observed in groups exhibiting more different sectoral composition. The evidence implies that, given other economic and financial conditions equal, economic union tends to share more consumption risk among its members that are more heterogeneous in their sectoral composition. These days, many countries aim to form FTA and other forms of economic integration. We suggest that they should pay attention to sectoral composition for member countries to minimizes income shock in the integrated economy.

양계산업에서 태풍의 핵인 고병원성조류인플루엔자가 또 다시 국내에서 상륙하며 양계산업에 긴장감이 감돌고 있다. 지금까지 HPAI가 전라도 익산·거제지역과 충남 아산에 총 4차례 발생하면서 추후 AI 확산에 대한 두려움이 사라지지 않고 있다. 현재까지 익산ㆍ김제 위험지역내 가금류 및 김제 경계지역 농장에서 총 1,121천마리(171농가)가 살처분되었다. 방역당국에서는 발생지역은 물론 집단 사육지역을 중심으로 방역활동을 강화해 나가고 있으며, 소비감소에 따른 가격하락으로 인해 전국적으로 소비홍보활동이 지속적으로 이루어지고 있다. 한편 21일에 충남 아산 종오리 농장에서 정밀검사결과 HPAI로 판명되면서 AI가 확산되는것이 아니냐는 불안감이 가중되고있어 그 추이를 지켜봐야 할 것으로 보인다

본 논문에서는 전기 자동차 충전소의 전력 소모량 추정 알고리즘을 웹 서버에 도입하여, 충전소에 의한 전력소비가 주변 전력 계통에 미치는 영향을 모니터링할 수 있는 시스템을 제안한다. 우선, 관련 기관으로부터 공급 받는 지역 내 실시간 충전소 별 이용 상태 정보로부터 충전 시간과 그 횟수를 도출하고, 이를 충전소 마다 누적하여 소비 전력을 추정한다. 이렇게 추정된 충전소 별 전력 소모량을 웹 페이지를 통해 사용자에게 시각화하여 제공한다. 또한 같은 지역의 구간별 실시간 교통량 또한 같은 방식으로 제공하여, 전기 자동차 충전소 전력소모량의 변화 추이와 교통량의 변화 추이 간 상관관계를 확인할 수 있도록 한다. 따라서 제안하는 시스템은 지역 내 전기 자동차 충전소의 전력 소모량 및 그 변화 추이 관측하고 이를 바탕으로 지역 내 충전소 추가 설치 필요성, 전력 계통 부하 예측, 충전소 재배치 등 전기 자동차 충전소 운영 전략을 수립하는데 사용할 수 있다.

Lead isotope ratios in horse-shaped bronze buckles excavated from the Songjeol-dong site in Cheongju and the mid-western region of the Korean Peninsula have been determined by thermal ionization mass spectrometry. The lead isotope ratios of the samples with data provenance were plotted in zone 3 of the South Korean galena map. The results indicated that the horse-shaped bronze buckles could be made using galena located in the same area as the archaeological site. These results can be used as basic data for comparison purposes in future studies on the manufacturing technology and provenance of bronze artifacts.

본 연구는 지난 12월(12월 10일 ~ 12월 23일) 충청남도 서부권 지역에 거주하는 가구(515개)를 대상으로 2015년 하반기에 발생한 가뭄으로 인한 물 소비 패턴을 조사하고, 이를 통해 해당 지역의 수돗물 소비 특성과 소비 구조에 미친 영향을 분석하였다. 우리나라 물 공급 상황, 가뭄의 심각성, 용도별 가구 내 수돗물 소비 실태와 수돗물 절약에 대한 인식 및 노력 정도를 조사하였다. 수돗물을 절약하고 있는 가장 큰 이유는 우리 지역의 가뭄 극복에 동참하기 위해서'가 73.2%로 가장 많았으며, 그 다음으로는 '수도요금 절약으로 가계 지출을 절감할 수 있어서'(55.9%), '정부의 물 절약 홍보'(52.4%) 등의 순으로 많이 나타났다.

수은이 함유된 방전등과 같은 조명기구의 사용이 제한되는 특수구역의 산업용 조명설비로 200 W 이상의 높은 소비전력의 백열등기구들이 사용되고 있다. 인공광원으로 백열전구는 매우 낮은 발광효율로 전력소모가 많고, 높은 방사열로 인해 화재의 염려가 있어 램프보호유리구를 장착하므로 낮은 조명률로 광 손실이 높게 발생한다. 또한 산업지역 내에서는 일반적으로 각종 전동기 및 공기조화 설비의 가동으로 진동이 심하며 여기에 백열전구 사용 시 당초 예상되는 수명보다 더욱 단축되고 있다. 이러한 지역에 설치된 백열등을 조명등기구 효율(Luminaire Efficacy)이 높은 친환경 에너지 절감형 차세대 광원인 LED조명등으로 대체하여 산업설비 지역 내 공급되는 조명용 소비전력을 크게 줄여 에너지 절약효과를 높임과 동시에 양호한 조명율의 LED광원을 사용함으로써 조명환경 개선에 따른 작업능률을 높이기 위해 특수지역의 산업용 LED조명등을 개발하였다.

This paper analyzes the relationships among the energy consumption, renewable energy production, real gross regional domestic product(GRDP), and greenhouse gas(GHG) emissions. It uses the metropolitan city and province level data for Korea from 2010 to 2018, employing a panal vector autoregressive(VAR) model. We find that an increase in energy consumption has a limited impact on boosting renewable energy production or gross regional domestic product, while it leads to an increase in greenhouse gas emissions. A rise in renewable energy production can increase gross regional domestic product, but it has no meaningful effects on energy consumption and the reduction of green house gas emissions. Our finding indicates that it is crucial to expand the supply of renewable energy as well as to decrease energy consumption in order to achieve the goal of reducing greenhouse gas emissions and reaching economic growth.

We focus on two kinds of game currency in online games, Game Money and Cash Money, and investigate how money expenditure behavior is explained by experience, achievement, and region as well as how the interplay among key variables differs between Game Money and Cash Money. The empirical analysis provides the following findings. First, experience increases Game Money expenditure whereas it lowers Cash Money expenditure, which suggests that gamers substitute gaming efforts for cash. Second, achievement is positively correlated with both kinds of game currencies. Finally, the relationship of money expenditure with experience and achievement is moderated by region. Specifically the negative effect of experience on Cash Money expenditure is more pronounced in suburban areas than in urban areas. The positive effect of achievement on Cash Money expenditure is also more pronounced in suburban areas than in urban areas. The authors conclude the paper with theoretical contributions and practical implications.

Despite the importance of prenatal nutrition, many studies find inadequate calcium intake among pregnant women. The purpose of this study was to investigate the value of the Theory of Planned Behavior in explaining the intentions and the actual consumption of milk among pregnant women participating in or eligible for WIC. A cross-sectional survey was conducted to collect information regarding attitudes, subjective norms, perceived control, milk allocation within the family, intentions and consumption of milk. The survey questionnaire was developed using open-ended questions and interviews with 112 pregnant women. One-hundred-eighty women recruited from prenatal clinics completed the survey questionnaire. Multiple regression was used separately to investigate the association of factors to intentions and to the consu-mption of milk, as proposed in the theory. Milk allocation within the family was used as an exploratory variable to explain milk consumption. Study findings revealed that all three factors, attitudes, subjective norms and perceived control contributed to the model in explaining intentions (explained variance : 36.2%), with perceived control being most important. For milk consumption, intentions and perceived control were related significantly to actual consumption, while milk allocation within the family was not (explained variance : 44.6%). These findings suggest that perceived control is important in understanding both intentions and milk consumption, providing empirical evidence for the Theory of Planned Behavior. With respect to the role of perceived control, more strong evidence was provided in explaining intentions. Findings suggest that educational interventions to increase milk consumption among pregnant women should incorporate strategies to enhance the perception of control, and to strengthen positive attitudes and to elicit social support from significant other.

The 4 major rivers restoration project (4RRP) requires the government to invest a lot of money. Regional economic effect is one of the main purposes of implementing the 4RRP. This paper attempts to measure the regional economic effects, focusing on regional employment-inducing effect and regional income-inducing effect. Regional employment-inducing effect is computed by excluding indirect effect and directly investigating the amount of employment. To this end, marginal propensity to consume, household consumption, household income should be derived. We used working day data and government expenditure multiplier to measure local employment creation and income generation. As a result, the project creates 46,628 employments from 2009 to 25 August 2011 and generates 25 trillion won regional income for three years.
