본(本) 연구에서는 에너지절약을 위한 주요 정책수단(政策手段)인 저리융자나 세제감면 또는 특별감가상각 인정 등 에너지절약 비용측면의 금융 세제지원이라는 과인성(課引性)정책과, 에너지수요조절를 위한 에너지가격 규제해제(energy price deregulation)나 에너지세(稅)의 추가부과 등 가격관리(조세) 정책의 경제적 효과를 비교 분석하였다. 그리고 에너지세(稅)부과의 경우 과세단계별 효과분석을 통하여 바람직한 과세포인트를 선택하고, 이를 통하여 현행 에너지절약 지원(支援)정책이나 에너지가격 및 조세체계에 대한 개선방향을 모색하였다. 분석결과, 약간의 물가상승 압박효과를 감수하더라도 에너지가격통제 해제나 에너지세 부과가 금융 세제지원제도에 비하여 에너지절약에 있어 그 효과가 크게 나타났다. 또한 에너지과세의 경우 그 대상과 실행시기에 대해서도 신축성을 기하는 것이 바람직한 것으로 나타나 에너지의 소비감소라는 효율성 측면과 함께 수반되는 물가압박요인을 고려하여 신중히 결정되어야 할 것으로 보인다. 그렇지만 단기적으로 에너지가격의 상승을 감수하더라도 DSM 프로그램비용을 자본화해 나감으로써 점진적으로 가격상승요인을 흡수하고 효과적인 에너지소비의 절약을 통하여 국민경제의 에너지비용을 줄여나갈 수 있는 종합적인 에너지대책이 마련되어야 할 것이다.

본 연구는 에너지정책을 종합적 차원에서 일반경제정책과 병행하여 정량적으로 분석할 수 있는 수리모형 (numerical multi-sector general equilibrium model)을 개발하기 위하여 시도되었다. 모형은 크게 (i) 가격/기술변화 반응적인 투입-산출계수를 내생화한 "산업간 거래모형 (inter-industry production model)", (ii) 민간에 의한 최종부문 수요를 나다내는 "소비자 선택모형 (consumer choices model)", 그리고 (iii) 생산물시장과 본원적 투입요소시장, 수출입시장 등에서 민간기업 정부 및 해외라는 개별 경제주체간의 행태를 반영하는 "거시경제 (성장) 모형 (macro-econometric growth model)"으로 구성되어 있다. 이러한 방법은 분석경제를 충분히 세분하고 제(諸)경제변수들의 동시결정적 과정을 중시한 일반균형적 /부문적 접근방법 (general equilibrium/sectoral approaches)을 취함으로써 지금까지 단순한 거시경제모형(aggregate macroeconomic models)이나 전통적 산업연관모형 (static input-output models)에만 의존해 오던 경제예측이나 경제 및 에너지관련 정책의 효과분석이 한층 더 강화될 수 있을 것으로 기대된다.

일반적으로, 전력시장은 가격기능을 통하여 공급과 수요의 균형을 이룬다. 경쟁적 전력시장은 가격신호를 통하여 공급측에는 투자 유인을 북돋우고 수요측에는 수요 감소 등의 반응을 유도한다. 이와 같은 전력시장의 특성상 본질적으로 가격 변동성과 신뢰도 유지 및 확보 문제가 수반된다. 본 연구에서는 에너지 단독시장에서의 가격신호를 보완해주는 효과를 지닌 용량의무 mechanism을 선택한 PJM 시장을 중심으로 분석함으로서 해외 전력시장에서의 적정 설비공급 메커니즘을 분석하고자 한다. 따라서, 본 연구의 결과는 향후 우리의 전력시장 설계 및 운영에 일조하리라 믿는다.

키네시오 테이핑은 일반 테이핑과 함께 다양한 분야에서 쓰이고 있으며 그 효과에 대한 연구 또한 다양하게 진행되고 있다. 우리는 키네시오 테이핑과 테이핑이 제자리 점프 시 발목 관절의 균형에 어떠한 영향을 미치는가를 알아보기 위해 다음의 실험을 고안하였다. 11명의 피험자에게 제자리 점프 시 발목관절의 움직임을 맨발, 테이핑 적용, 키네시오 테이핑 적용후로 나누어 시상면의 각도 변화를 통해 평가하였다. 테이핑은 근피자극효과에 초점을 맞추어 발목 관절의 움직임을 제한할 정도로 적용하지는 않았다. 그 결과 키네시오 테이핑과 테이핑 모두에서 줄어든 각도 변화가 관찰되었으나 유의한 차이값을 보여주지는 않았다. 그러므로 키네시오 테이핑과 테이핑(근피자극효과)이 발목관절의 안정성에 효과가 있는지에 관한 문제는 추가적인 연구가 필요할 것으로 보인다.

The process of segmenting customers in CRM should take into equal consideration both the companies' and customers' expected value. However, most of the current studies on customer segmentation have focused only on the companies view in terms of profitability. This study focuses on clarifying a problem and proposing a modified view in the customer segmentation step. The authors offer a proposition which is beneficial to both customers and companies, and thus makes the segmentation step more balanced. There is a two-pronged focus on customer segmentation in this study: first, this paper proposes a balanced view considering not only companies' expected value, but also that of the customers'. Secondly, such balanced segmentation will give a more accurate definition of loyal customers for a given company. This new approach can be expected to improve the level of satisfaction and the length of customer retention, and to increase effectiveness in corporate resource allocation for customer target marketing, as well as improve company insight into customer needs and preferences.

Recently, flipped learning has been paid much attention as one of the improvement methods of teaching and learning at university level. Few studies investigated the effects of flipped learning in general physics classes. However, in order to be successfully established and spread new attempts such as flipped learning, it is necessary to investigate in detail the effect of flipped learning and the way it is perceived by students in accordance with other variables such as student's background and characteristic. In this study, we investigated differences in students' perception on the flipped learning and their achievement according to their background and characteristic in flipped-learning-based introductory physics course in which class hours are divided into lecture and group problem solving equally. Students' achievement was more influenced by their readiness before the beginning of the semester than their time consuming for learning during the semester. Students generally had a very positive perception of the new way of flipped-learning-based physics teaching. However, students of insufficient prior learning, or relatively not-hard learner agreed with careful selection of subjects rather than the overall expansion of flipped learning.

Purpose: We examined the effects of the 8-week moderate-intensity Pilates exercise program on body composition, balance ability, metabolic parameters, arterial condition, and eating habits among overweight and obese women. Methods: From the general sample of overweight or obese Korean women (body mass index ≥ 23 kg/m² ), those who had not been diagnosed with any chronic degenerative diseases were enrolled in the study (n = 39). After 8 weeks of the Pilates exercise program, the participants were subdivided into adherence and non-adherence groups. Among the study participants, 24 women were matched for age and menopausal status to reduce the bias, and then finally included for the comparison (Pilates-adherence, n = 12; Pilates-non-adherence, n = 12). Results: The body balance measured by the Y-balance test, body mass index, and subcutaneous fat areas were significantly improved in both groups. However, the Pilate-sadherence group showed more positive changes in body balance and had significant improvement in body composition parameters such as waist size, visceral fat area, systolic blood pressure, arterial aging index, fasting blood glucose, and glycated hemoglobin than the Pilates-non-adherence group. In addition, the nutrition quotient for Korean adults (balance, moderation, and behavior except diversity) were significantly improved in both groups after dietary education. However, the participants did not show dramatic improvement in the metabolic parameters, because all the study subjects were in relatively good health and did not have any diagnosed diseases. Conclusion: This study demonstrated that higher adherence to the Pilates exercise program together with a modification of eating habits may effectively improve body balance, body composition, and obesity-related parameters among overweight and obese women.

This study approached the elderly in Korea with a systematic review to find out the effect of virtual reality program arbitration on balance, which the evidence for the virtual reality program is provided. Total of 94 papers were searched through the database Nuri Media (DBpia), Scholarship (earticle), Korean Studies Information (KISS), National Digital Science Library (NDSL), the Korea Educational Research and Information Service (RISS), Kyobo Book Scholar (RISS), and Hakjisa New Thesis on Literature Selection using PRISMA flow-chart from January 2005 to May 2020 based on the final literature selection process and analysis. The quality level of the literature was found to be three volumes (50.0%) of the base level I, one (16.7%) of the II, and two of the III (33.3%). The most common type of virtual reality program was Wii-fit balance of 4 (66.7%), and the effect of virtual reality program arbitration was significant overall through evaluation tools for balance and walking ability. This is expected to effectively apply the virtual reality program to the elderly. In addition, since clinical application basis has been provided, further studies applying various virtual reality program interventions need to be addressed.

A computable general equilibrium model has been used to analyze the likelihood of double-dividend effect in Korean economy. Revenue neutral introduction of carbon tax through the reduction in payroll tax and corporate income tax had been experimented in this regard. Double-dividend measured by income shows the existence of weak double-dividend in both cases, while double-dividend measured by consumption level could not be found in case of carbon tax with corporate income tax reduction. A notable result is in the employment measured double-dividend effect as the sizable strong double-dividend effect were found in the case of carbon tax with payroll tax reduction.

This study analyzed the ripple effect of the demand-side support for start-up venture companies on the macro economy using Dynamic General Equilibrium model. In the model, start-up venture companies were expressed in a manner that distinguished between workers and entrepreneurs by applying the span of control in the Lucas(1978). As a result of the analysis, when the share of public procurement of start-up venture companies was increased from 5.7% to 10%, the actual production of start-up venture companies increased by about 46.17% and the number of venture companies increased by about 150%. In addition, it was analyzed that the number of jobs through venture companies increased by about 61.56%. In addition, it was found that the economic effect was greatly reduced when the start-up venture company was supported as a subsidy for the supply sector with the same amount as the public procurement support. This is interpreted as the fact that if the government implements the supply-side support policy, the expansion of supply causes the price of start-up venture companies to fall, reducing the effect of the support policy in half. Therefore, when supporting start-up venture companies, the government should make efforts to maximize the policy effect by expanding the demand-side support through public procurement and reducing the payment of simple subsidies to start-up venture companies.
