In the growth of the government's investment in national R&D project and the abuse of research expense, an effective control and management mechanism is strongly demanded. However, an excessive regulation might hinder the R&D performance, which also endangers the underlying objective of R&D policy. Especially, an excessive regulation on the R&D expenditure may damage the SMEs (Small and Medium sized Enterprises) where securing an adequate level of R&D funding is vital. This study investigates the R&D funding and R&D performance of SMEs participating in the national R&D project by using fixed effect panel model. As a result, this paper reveals the effectiveness of 'Government R&D subsidy'. However, that of 'private R&D fund' is not supported strongly. Also, this paper empirically demonstrates the efficiency of both 'Government R&D subsidy' and 'Private R&D fund' as the R&D costs are spent discretionarily (as the degree of 'Indirect Cost Ratio' increases). Especially, the effectiveness of 'Private R&D fund' can be moderated by 'Indirect Cost Ratio'. On the basis of the conclusions, this paper draws an implication that can increase R&D performance of SMEs through the interactions of manifold administrative values (i.e. effectiveness, efficiency and responsibility).

선물의 만기효과는 선물의 만기일에 가까워질수록 선물가격의 변동성이 증가하는 현상으로 사무엘슨 효과라고도 하는데, 이는 선물가격의 행태를 이해하고 투자전략과 헤지전략을 수립하는 데 매우 중요하다. 그 동안 미국을 비롯한 선진국에서 이에 대한 많은 실증연구가 있었다. 본 연구에서는 KSE의 KOSPI 200 지수선물과 KOFEX의 CD 금리선물, 국채선물, 미국달러선물, 금선물을 대상으로 선물가격의 만기효과를 검정하였으며, 그 결과는 다음과 같다. 먼저, Conover 제곱순위검정과 F-검정의 결과, KOSPI 200 지수선물에서는 만기일에 가까워질수록 변동성이 증가하는 만기효과가 나타난 반면에 CD 금리선물과 국채선물에서는 만기일에 가까워질수록 변동성이 오히려 감소하는 역 만기효과가 나타났다. 그러나 미국달러선물과 금선물에서는 만기효과를 판단하기가 어려웠다. 나아가, 연도효과를 통제한 회귀분석 결과, KOSPI 200 지수선물에서는 5% 수준에서 유의한 만기효과가 나타났다. 이는 금융선물에서 만기효과를 처음으로 발견한 Milonas(1986)의 연구와 일치하지만, Chen-Duan-Hung(1999)의 연구와는 상반된다. 그리고 CD 금리선물에서는 1% 수준에서, 그리고 국채선물에서는 5% 수준에서 각각 유의한 역 만기효과가 나타났으며, 미국달러와 금 선물에서는 만기효과가 나타나지 않았다. 또한 CD 금리선물을 제외한 KOSPI 200 지수, 국채, 미국달러 및 금 선물에서 모두 1% 수준에서 유의한 연도효과가 나타났다. 이는 Milonas-Vora(1985), Khoury-Yourougou(1993), Galloway-Kolb(1996) 등의 연구와 일치한다.

The purpose of this study was to analyze effectiveness of 4-H Seoul Field-Experiential Learning Program(4-H SFELP). The effectiveness scale of youth accredited activity was applied to analyze the effectiveness and satisfaction of the program. After screening the data, 155 responses were used to analyze the data for this study. The major findings of this study were as follows. First, 4-H SFELP has positive effects on the level of global leadership, initiative in exchange, and understanding other cultures which are related with effectiveness of youth exchange activity. Second, 4-H SFELP has positive effects on the level of confidence, challenge spirit, achievement motivation, and collective leadership which are related with effectiveness of youth adventure and challenge activity. Third, 4-H SFELP has positive effects on the level of problem-solving skills, morality, other-respect, and self-respect which are related with effectiveness of youth self-improvement activity. Fourth, 4-H SFELP has positive effects on the level of self-efficacy and autonomy but has not effects on the level of inquiring mind of participants. All these findings were discussed for youth workers and researchers.

본 연구는 KOSPI 200 선물시장의 거래자료를 이용하여 시장의 미시구조에 의한 하루중 수익률, 변동성 및 거래량 형태를 검토하였다. 본 연구의 주요 결과는 다음과 같다. 첫째, 지수선물시장의 하루중 변동성과 거래량 형태는 일말효과보다 일초효과가 크게 나타나는 조잡한 W자형 형태이다. 이러한 형태는 Brock-Kleidon(1992)의 시장폐장이론에 의해 설명되지만, 동시호가제 등 국내시장의 운영제도에 의해서도 영향을 받고 있음을 보여준다. 둘째, 현물시장의 폐장시간대의 변동성 감소는 한 금융시장의 폐장에서 다른 관련 금융시장의 가격변동성 하락을 예측한 King-Wadhwani(1990)의 이론적 연구결과와 일치한다. 셋째, 수익률의 하루중 형태는 요일에 따라 상이하며 매우 노이즈한 행태를 보여주었다. 그리고 수익률의 요일효과 분석에서 일주일 중 가장 낮은 수익률이 화요일에 발생하는 화요일 효과를 발견하였다. 월요일 효과도 발견되었지만, 그 크기면에서 화요일 효과가 지배적이었다.

This study sought to identify the interactive relationship between the individual cognitive characteristics of perceived consumer effectiveness and the impact of the message framing type of a fashion brand's sustainable marketing on consumers' brand trust. As a result of the study, it was confirmed that the fashion brand's message framing type increased consumers' perceived consumer effectiveness, and that the recipient's perceived consumer effectiveness each influenced the formation of consumers' trust in the brand. It was confirmed that the fashion brand's message frame directly had a positive effect in forming consumers' brand trust.

This study analyses a productivity effect by E&T and R&D activities via estimation of E&T stock, R&D stock, and patent stock in a corporate level. Particularly, the analysis reflects the effects of skilled training after estimating E&T stock from E&T flow. When a spillover effect of E&T is analyzed, a methodology using technical proximity concept becomes a new experiment. Also classifying long and short term effects from the usage of Dynamic Panel Data Analysis becomes a new trial, too. The results of study appear that the productivity effects from E&T investments are relatively lager than R&D investments. Through spillover effects and long-term effects E&T and R&D activities have a strong influence on the corporate's productivity.

This study analyzed the perception of effectiveness and satisfaction according to learners' background variables and characteristics in online gifted education program. The participants included 630 middle and high school students who attended the 3-months online gifted program. Participants volunteerly surveyed on background and characteristics such as gender, grade, subjects, self-efficacy of internet, and self-regulated learning, and the effectiveness and satisfaction of the online gifted education program. T-test, ANOVA, and MANOVA were conducted to analyze the effect of students' background and characteristics on various dependent variables. The results of this study showed that (1) overall, participants perceived the effectiveness of the online gifted program positively; (2) participants perceived the satisfaction of the online gifted program positively. In specific, they perceived system satisfaction higher than interaction satisfaction. (3) the personal characteristics which impacted on both effectiveness and satisfaction were grade, self-efficacy of internet, and self-regulated learning. Suggestion for the online gifted education program were discussed.
