청소년 기업가정신에 관한 관심과 기업가정신 교육의 필요성이 중요시됨에 따라 초·중·고등학교 교육과정부터 체계적인 기업가 정신 교육이 강조되고 있으며, 이와 관련한 연구의 필요성이 대두되고 있다. 본 연구는 청소년을 대상으로 기업가정신, 긍정심리자본이 창업의지에 미치는 영향과 기업가 정신교육의 만족도가 조절효과를 갖는지 여부를 확인하고자 하였다. 이를 위해, 성별과 부모 창업의 여부를 통제한 상태에서 기업가정신의 주요 구성요소 '진취성', '위험 감수성', '혁신성'과 긍정심리자본의 '희망', '자기효능감', '회복 탄력성', '낙관주의'를 독립변수로 하였는데, 기업가정신 교육 프로그램에 참여한 청소년(중학생) 총 204명의 응답을 회수 후 실증분석을 시도 했다. 또한 기업가정신 교육의 만족도를 조절변수로 하는 연구 모형을 상정하였는데, 이는 기업가정신 및 긍정심리자본과 창업 의지의 관계에서 기업가정신 교육의 만족도가 조절 효과 여부를 확인하여 기업가정신 교육의 중요성을 밝히고 활성화를 목적으로 하고 있다. 이를 통해 잠재적 창업가가 될 수 있는 청소년의 기업가정신 영향요인을 검증하고 연구자료에 다양하게 비교할 수 있는 참고자료로서 도움이 되고자 한다.

한국 종합주가지수는 한국증권거래소에 상장된 모든 기업들의 가치 가중치에 의한 포트폴리오의 가격의 시계열이라고 할 수 있다. 따라서 이 지수는 한국 경제의 현재의 활동과 미래의 활동에 대한 예상의 총합의 반영 또는 표상을 표현하는 정보라 할 수 있다. 본 논문에서는 시차변수가 독립변수로 도입될 수도 있으며, 시차변수가 아닌 변수가 독립변수로 도입되는 것이 허용되는 회귀모형을 통하여 구조변화의 회수와 구조변환점을 검정할 수 있는 통계량과 이 통계량의 확률분포를 분석하고 한국 종합주가지수에 적용하여 한국 종합주가 지수의 일별수익률에 구조변화가 발생하였는지의 여부와 발생했다면 발생회수와 변환점들을 발견하는데 그 목적이 있다. 한국 종합주가지수의 일별수익률은 분산의 변화 그리고 평균 및 분산의 동시변화가 1997년 9월 27일에 발생하였다. 자기회귀모형에 의할 때 증권시장의 구조변화는 1999년 11월 16일에 이루어졌다. 평균과 분산의 변화가 일어나 구조변화의 단계를 시작하고 구조변화에 알맞는 환경조성에 2년이 소요된 후에 1999년 11월 16일에 구조변화가 정착되었다. 정착이 이루어진 후에야 비로서 이 두 기간은 서로 다른 경제구조와 증권시장구조가 이루어지고 이에 입각하여 시장의 새로운 운동법칙이 전개되고 있다고 할 수 있을 것이다.

The objective of this study is to evaluate the economic feasibility of two fast pyrolysis and biooil upgrading (FPBU) plants including feed drying, fast pyrolysis by fluidized-bed, biooil recovery, hydro-processing for biooil upgrading, electricity generation, and wastewater treatment. The two FPBU plants are Case 1 of an FPBU plant with steam methane reforming (SMR) for $H_2$ generation (FPBU-HG, 20% yield), and Case 2 of an FPBU with external $H_2$ supply (FPBUEH, 25% yield). The process flow diagrams (PFDs) for the two plants were constructed, and the mass and energy balances were calculated, using a commercial process simulator (ASPEN Plus). A four-level economic potential approach (4-level EP) was used for techno-economic analysis (TEA) under the assumption of sawdust 100 t//d containing 40% water, 30% equity, capital expenditure equal to the equity, $H_2$ price of $1050/ton, and hydrocarbon yield from dried sawdust equal to 20 and 25 % for Case 1 and 2, respectively. TCI (total capital investment), TPC (total production cost), ASR (annual sales revenue), and MFSP (minimum fuel selling price) of Case 1 were $22.2 million, $3.98 million/yr, $4.64 million/yr, and $1.56/l, respectively. Those of Case 2 were $16.1 million, $5.20 million/yr, $5.55 million/yr, and $1.18/l, respectively. Both ROI (return on investment) and PBP (payback period) of Case 1(FPBU-HG) and Case 2(FPBU-EH) were the almost same. If the plant capacity increases into 1,500 t/d for Case 1 and Case 2, ROI would be improved into 15%/yr.

This study was conducted to verify the effects of individual psychological capital, spousal support, and organization's family-friendly work culture on work-life balance in social workers. For this purpose, married social workers working in social welfare facilities in Chungcheongbuk-do were surveyed, and 331 collected responses were used in the analysis. Multiple regression analysis revealed that resilience and optimism in individual psychological capital, spousal support, and expectations on working hours in organizations' family-friendly work culture were significantly associated with the work-life balance. In addition, there were different factors influencing the level of work-life balance according to gender and age. The findings suggest that efforts to enhance awareness and improve working conditions, such as the development of self-care program, education on the necessity of work-life balance, and implementation of work-life balancing system, are needed to improve the work-life balance of social workers.
