이학동,김숙향,노경임,손연아 韓國生物敎育學會 1996 생물교육 Vol.24 No.1

This study has been performed to achieve two objects. They are as follows. To analyze a status on the preservice teacher education in the departments of science education and then search the ways of the improvement. To analyze a status on teaching practice-cooperation between universities and secondary schools which are practiced by the student teachers and then search the ways of the improvement. To perform this study, first, the servey is collected and analyzed by 19 universities installed departments of science education. Second, professors of the departments of science education, principals and vice-principals of the practicing secondary school, and student teachers majoring in science education are interviewed and discussed together to analyze status on the preservice education. The conclusions of this study can be summarized as follows : 1. In teaching for the field of majoring-science, a cooperating-system between the departments of science education and the departments of science is needed. 2. In the field of teaching profession, the subject, the relative importance of credit and system are needed to be improved. 3. In the field of subject-education(especially, in middle school science and integrated science), the reinforcement and reorganization are needed. 4. The field of teaching practice is asked separation and independence in the curriculum for preservice education. The recognition for the importance should be emphasized. 5. The reorganization of 3 and 4 should be regulated connecting with the requisite 150 credits for the students who major in science education. 6. The practical and educational cooperation between universities and the practicing secondary schools can be possible by appointing the fixed cooperation-schools. More effective preservice education of science teachers can be accomplished by establishing the concrete program for the presented conclusions.

중학교 과학교사 양성을 위한 교육과정의 개선 방안

이학동 한국과학교육학회 1989 한국과학교육학회지 Vol.9 No.1

From the investigation perfomed by this writer in 1986, it was recognized that many science teachers are in difficulty in teaching the intergrated science in secondary schools and then the present teacher preparation programs need improvement to advance the quality of science teachers. To set up the improvement model, the preservice programs in the departments of science education in Korea were intensively analyzed and compared with that in the department of science education in Hiroshima university. The results of analysises on the programs showed the needs for improvement. A improvement model of the program for secondary science teacher preparation was set up as follows; 1. The improvement program is set up to emphasize the basic science course such as, general physics, chemistry, etc. 2. More emphasis is put upon the intergrated science course. 3. The improvement program is a practical one which is suitable to apply directly as a program in the department of science education.

경영자 능력이 투자효율성에 미치는 영향 : 중국 신삼판(新三板)기업을 중심으로

장학동,강신애 한국경영컨설팅학회 2023 경영컨설팅연구 Vol.23 No.1

포스트 코로나시대 경기침체가 지속되면서 기업의 투자심리가 위축되고 있다. 이러한 상황에서 경영자가 수익성이 있는 투자안을 발굴하여 효율적인 투자를 하는 것이 무엇보다 중요하며, 기업의 투자도 규모가 있는 투자에서 효율성이 있는 투자로 전환해야 하므로 기업의 각종 투자 결정을 지닌 경영자의 능력이 매우 중요하다. 따라서 본 연구는 2014년부터 2021년까지의 중국 비상장 중소기업들의 지분거래를 위한 장외시 장인 신삼판시장 기업 중 12월 결산법인 기업자료를 이용하여 경영자 능력이 투자효율성에 미치는 영향을 분석하였다. 구체적으로, 기업의 투 자효율성은 Richardson(2006) 모형을 참고하여 측정하였고, 경영자 능력지수는 Demerjian et al.(2012)의 연구에서 제시된 DEA-Tobit회귀 2단 계 모형을 통해 산출하였다. 분석 결과 먼저 전체기업표본에서 경영자 능력이 기업의 최적투자액을 벗어나는 비효율성 투자와 1% 수준에서 유의한 음(-)의 값으로 확인 하였다. 즉, 경영자 능력이 높을수록 기업의 비효율성 투자를 감소시킬 수 있으며, 투자효율성에 대한 양(+)의 관련성을 가지는 실증적 증거를 보고하였다. 또한, 투자부족 표본에서도 경영자 능력이 비효율성 투자와 1% 수준에서 유의한 음(-)의 관계를 보여주었으나, 투자과대 표본에서 는 유의하지 않은 음(-)의 값으로 나타났다. 이러한 결과는 투자부족에서 경영자 능력이 투자에 미치는 영향이 더 강하게 나타났으며, 경영자 능 력이 높을수록 기업과 산업에 대한 높은 이해를 바탕으로 자신 있게 투자하기 때문에 투자부족의 가능성을 강하게 감소시키기 때문이다. 투자 과대 표본에서 유의하지 않은 관계가 나타난 것은 중국 중소기업들은 창업자 또는 창업자 가족이 기업의 소유자이면서 경영자인 지배구조 특징 을 가지기 때문에 경영자는 단기보다 장기이익의 최대화, 규모의 효과, 높은 시장점유율 및 매출을 추구하는 경향이 있다. 비상장 중소기업들의 지분거래시장인 신삼판 시장에서 기업의 경영자는 규모의 효과 및 높은 시장점유율 및 매출을 위해 투자부족 문제를 적극적으로 감소시키며, 투자과대에 대해 오히려 간섭하지 않는 것이라 해석할 수 있으며, 독립변수가 t-1년도의 값을 취하여 회귀분석한 결과도 이와 동일한 결과를 확 인하였다. 이외에도 기업이 보유한 자원 및 자금의 효율적 활용을 대리하는 변수로 총자산회전율을 사용하였다. 총자산회전율을 매개변수로 하여 회귀분석한 결과 총자산회전율이 경영자능력과 투자효율성간에 매개효과가 존재한다는 것은 확인하였다. 추가분석에서도 기업의 등록상 태 및 속한 산업별에 따라 경영자 능력이 기업 투자효율성 간의 유의한 양(+)의 관계를 발견하였다. As the economic recession continues in the post-COVID-19 era, corporate investor sentiment is shrinking. In this situation, it is most important for managers to find profitable investment plans and make efficient investments. In addition, since corporate investment should also be converted from large-scale investment to efficient investment, the ability of managers with various investment decisions of companies is very important. Therefore, this study analyzed the effect of managerial ability on investment efficiency using corporate data from the Chinese New Third Board market whose settlement month is December from 2014 to 2021. Specifically, corporate investment efficiency was measured by referring to the Richardson (2006) model, and the managerial ability index was calculated through the two-step model of DEA-Tobit regression presented in the study of Demerjian et al. (2012). In addition, the under-investment sample showed a significant negative (-) relationship between managerial ability and inefficiency investment at the 1% level, but the over-investment sample showed non-significant negative (-) value. This result shows that managerial ability has a stronger impact on investment in the under-investment sample, and the higher managerial ability, the more confidently invest based on a high understanding of companies and industries, which strongly reduces the possibility of investment shortage. There was a significant relationship in the over-investment sample because Chinese SMEs have a governance structure in which the founder or family of the founder is the owner and manager of the company, so managers tend to pursue long-term profits, scale effects, high market share, and sales than short-term profits. In the Shinsampan market, which is an equity trading market for unlisted small and medium-sized enterprises, corporate managers actively reduce the problem of lack of investment for the effect of scale, high market share, and sales, and rather do not interfere with investment overload. The results of regression analysis by taking the value of the independent variable in t-1 can also be confirmed to be consistent with this. In addition, the asset turnover rate was used as a variable representing the efficient use of resources and funds held by companies. As a result of regression analysis using the asset turnover rate as a parameter, it was confirmed that the asset turnover rate had a mediating effect between managerial ability and investment efficiency. Further analysis also found a significant positive (+) relationship between corporate investment efficiency in managerial ability according to the company's registration status and industry to which it belongs.
