본 연구는 초등학생의 독서를 장려할 수 있는 심리적 요인을 탐색하기 위해 이루어졌다. 구체적으로 목표 달성에 영향을 미친다고 알려져 있는 해석수준을 조작하여 독서량에 미치는 효과를 확인하였다. 이를 위해 본 연구는 초등학생 200명을 대상으로 연구를 수행하면서 평소 독서 선호도가 높은 집단과 낮은 집단, 그리고 평소 독서량이 많은 집단과 적은 집단으로 구분하였다. 또한 독서를 왜 해야 하는지에 대해 생각해보는 추상적 해석수준 집단과 독서를 어떻게 해야 하는지에 대해 생각해보는 구체적 해석수준 집단으로 구분한 후, 2주 동안의 독서량과 독서가 얼마나 재미있었는지를 측정하였다. 그 결과 해석수준의 주효과를 확인하였다. 즉 구체적 수준의 해석을 한 집단이 추상적 수준의 해석을 한 집단보다 독서량이 많았다. 또한 평소 독서 선호도가 낮은 집단은 독서에 대해 구체적 수준의 해석을 할 때 독서량과 독서에 대한 재미가 증진되지만, 평소 독서 선호도가 높은 집단은 해석수준에 관계없이 독서량이 많고, 독서에 대한 재미가 높은 상호작용이 관찰되었다. 아울러 평소 독서량이 적은 집단은 독서를 구체적 수준으로 해석할 때 독서량이 증가하고, 독서에 대한 재미가 증진되지만, 평소 독서량이 많은 집단은 독서를 추상적 수준으로 해석할 때 독서에 대한 재미가 증진되는 상호작용도 확인할 수 있었다. 본 연구는 행동경제학적 연구에서 다루어져 왔던 해석수준의 효과를 독서라는 교육적 지도 분야로 확장했다는 점에서 시사점을 가진다. 또한 평소 어떤 일을 선호하는 사람과 그렇지 않은 사람, 평소 어떤 일의 성과가 높은 사람과 낮은 사람에게 어떤 해석수준을 가지게 하는 것이 그 일에 대한 동기부여를 증진하는 것에 도움이 될 수 있는지 보여주었다는 측면에서 실무적인 시사점이 있다.

Drought is considered as a devastating hazard that causes serious agricultural, ecological and socio-economic impacts worldwide. Fundamentally, the drought can be defined as temporarily different levels of inadequate precipitation, soil moisture, and water supply relative to the long-term average conditions. From no unified definition of droughts, droughts have been divided into different severity level, i.e., moderate drought, severe drought, extreme drought and exceptional drought. The drought severity classification defined the ranges for each indicator for each dryness level. Because the ranges of the various indicators often don't coincide, the final drought category tends to be based on what the majority of the indicators show and on local observations. Evaporative Stress Index (ESI), a satellite-based drought index using the ratio of potential and actual evaporation, is being used as a index of the droughts occurring rapidly in a short period of time from studies showing a more sensitive and fast response to drought compared to Standardized Precipitation Index (SPI), and Palmer Drought Severity Index (PDSI). However, ESI is difficult to provide an objective drought assessment because it does not have clear drought severity classification criteria. In this study, U.S. Drought Monitor (USDM), the standard for drought determination used in the United States, was applied to ESI, and the Percentile method was used to classify drought categories by severity. Regarding the actual 2017 drought event in South Korea, we compare the spatial distribution of drought area and understand the USDM-based ESI by comparing the results of Standardized Groundwater level Index (SGI) and drought impact information. These results demonstrated that the USDM-based ESI could be an effective tool to provide objective drought conditions to inform management decisions for drought policy.

The purpose of this study is to examine the impacts of the physical health on health behaviors of the rural elderly. In this study, physical health is measured self-rated health and farmer symptoms. The specific questions addressed in this study are: What are the general tendencies of health behavior, self-rated health and farmer symptoms? What are the direct impacts and indirect impacts of respondents' characteristics, self-rated health and farmer symptoms on health behaviors of the rural elderly? For this purpose, survey data was gathered from 881 rural elderly who live in a village. The statistical methods used for data analysis were descriptive statistics, correlations, and path analysis with spsswin 12.0 program. The major findings of this study are as follows: The level of health behaviors and self-rated health is low and the level of farmer symptoms is high. In general, it can be said that respondents of this study have the low level of physical health and health behaviors. A path analysis shows the relation of variables, which influence on health behaviors. Economic status, education status and farmer symptoms play direct and positive effects on health behaviors. Especially, the effect of farmer symptoms is more important than the others. Sex and age are indirectly significant on health behavior. The results obtained from the study confirm that objective physical health, like as farmer symptoms, plays important roles in health behavior of the rural elderly. It means that the Korean rural elderly need many facilities and services to promote their physical health.

Demand response (DR) programs give opportunity to consumers to manage their electricity bills. Besides, distribution system operator (DSO) is interested in using DR programs to obtain technical and economic benefits for distribution network. Since small consumers have difficulties to individually take part in the electricity market, an entity named demand response provider (DRP) has been recently defined to aggregate the DR of small consumers. However, implementing DR programs face challenges to fairly allocate benefits and payments between DRP and DSO. This paper presents a procedure for modeling the interaction between DRP and DSO based on a bilevel programming model. Both DSO and DRP behave from their own viewpoint with different objective functions. On the one hand, DRP bids the potential of DR programs, which are load shifting and load curtailment, to maximize its expected profit and on the other hand, DSO purchases electric power from either the electricity market or DRP to supply its consumers by minimizing its overall cost. In the proposed bilevel programming approach, the upper level problem represents the DRP decisions, while the lower level problem represents the DSO behavior. The obtained bilevel programming problem (BPP) is converted into a single level optimizing problem using its Karush-Kuhn-Tucker (KKT) optimality conditions. Furthermore, point estimate method (PEM) is employed to model the uncertainties of the power demands and the electricity market prices. The efficiency of the presented model is verified through the case studies and analysis of the obtained results.

The COVID 19 pandemic has led to a new global recession and is still causing a lot of issues because of the delays in the employment of people. This scenario has severe consequences for many countries' labor markets in the world. This problem's complexity and importance requires an integrated method of subjective and objective evaluation rather than intuitive decisions. This research aims to investigate sustainable indexes for assessing the unemployment problem by using a Multi-Criteria Decision-Making Model (MCDM). Grey theory and Decision Making Trial and Evaluation Laboratory (GDEMATEL) are deployed to transform the experts' opinions into quantitative data. The analysis based on 20 crucial criteria is employed to determine the weights of sustainability of unemployment problems. The results revealed that the top ten of determinants are Economic growth, Industrialization, Foreign direct investment, Real GDP per capita, Education level, Trade Openness, Capacity Utilization Rate, Urbanization, Employability skills, Education system expansion, which have the most significant effects on the unemployment rate under COVID 19 impacts. Furthermore, GDEMATEL could effectively assess the sustainable indicators for unemployment problems in "deep and wide" aspects. The study proposes the Grey MCDM model, contributes to the literature, provides future research directions, and helps policymakers and researchers achieve the best solutions to the unemployment problems under "economic shocks."

Demands for housing has diversified recently due to low birth rate and the growth of aging population. Also, a share of idle houses and obsolete houses over 20 years old is gradually rising. Therefore, there is a need for a sustainable, environment-friendly improvement policy that is in line with a new housing paradigm and avoids full-scale new construction, such as a customized housing renovation plan considering local economic circumstances. Therefore, afforestation system applicable to buildings are assessed positively, but lack objective performance evaluation. Through one-year, long-term monitoring of replicated obsolete buildings that have poor insulation performance, this study calculated monthly average power consumption and analyzed power charges by applying pricing plans before and after the revision of progressive tax in order to examine economic effects expected by applying the afforestation system. In the obsolete buildings, the study showed that monthly average power consumption was reduced by 16.6kWh with 5.2% average reduction rate. Highest reduction was made in July at 11.3%. Aggregate monthly power consumption charges were relatively high in winter before and after the revision of progressive tax. Power charges reduction effect was highest in March when monthly power consumption was reduced to 300kWh level by applying the afforestation system.

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.

오늘날 산학 연구협력은 특히 과학 기반 기술 혁신과 연관되어 주요 정책 현안이 되고 있다. 그렇지만 산학 협력의 성격과 정도에 관한 대단위 체계적 계량 자료를 분석한 연구는 거의 없다. 이 논문은 7개 과학 기반 기술에서 과학적 지식 생산에 기여하는 산학 연구협력의 패턴과 추세를 탐구하였다. 세계의 주요 과학 저널에서 발행되는 공동저술 논문을 과학적 연구협력의 지표로 이용하여, 2006년부터 2010년까지 미국 동북부 지역에 주소를 두고 발행된 수만 편의 논문을 분석하였다. 본 연구는 과학 기반 기술에서 5인 이상이 협력하는 연구가 크게 증가하고, 동시에 국제적 협력의 비중이 점점 증가하여 가장 중요한 공간적 스케일이 되고 있음을 보인다. 조직 유형별 협력 형태에 따른 패턴을 비교한 결과, 동북부 지역의 산학 연구협력은 상대적으로 전국적 수준에서 활발하게 수행되고 있었다. 과학 기반 기술에서의 혁신정책은 지역은 물론 전국적 수준에서 수립되어야 할 것을 시사한다.
