A prompt subsurface runoff producing mechanism whih creaters a depletion curve of direct runoff hydrograph is simulated by a dead zone dispersion model technique. Runoff processes are carried out by routing of the outflow resulted from previous linear channel and effective rainfall from its corresponding subwatershed through a series of conceptual linear channels representing subwatersheds of a catchment. Working rules are explained for evaluation the model parameters such as translatory velocity, diffusive factor, and parameters concerning the infiltration and relative magnitude of the prompt subsurface flow region.

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.

Correlation between rice yield loss and infection time of neck blast after panicle emergence was analyzed in paddy fields at Icheon in 1999 and 2000. As the neck blast occurred at early heading stage, the yield loss of a early maturity variety, Jinmibyeo, ranged from 83.9% to 81.6%, while it ranged from 44.3% to 33.1% when the disease developed 30 days after heading. The regression equations of yield loss(y) caused by the neck blast infection time(x) in Jinmibyeo were y =1.2717x + 79.523(R2 = 0.9487) and y = 1.6872x + 74.545(R2 = 0.7993) in 1999 and 2000. In a mid-lately maturity variety, Chucheongbyeo, yield loss ranged from 64.9% to 47.8% when the disease developed at early heading stage. While it ranged from 29.1% to 8.9% when the disease occurred 40 days after heading. The regression equations of yield loss caused by the disease in Chucheongbyeo were y= 1.2717x + 79.523($R^2$ = 0.9487) and y = 1.6872x + 74.545(($R^2$ = 0.7993) in 1999 and 2000. Weights of 1,000 rice grains of Jinmibyeo and Chucheongbyeo were also drastically decreased to 38.3% and 57.3%, respectively, compared to healthy control when the disease occurred at early heading stage. However, weights of the two cultivars were 87.6% and 92.9% compared to control when the disease developed after 40 days of heading. Results indicated that there is a highly negative correlation between rice yield loss and infection time of the neck blast.

This study studied the effect of the TIPS support project of the Ministry of SMEs and Startups on the entrepreneurship of TIPS start-ups. The Tips start-up company, which is the subject of the study, was selected for the TIPS support project, participated in all commercialization funds, incubation facilities, and capacity building programs, and was selected as a company that received private investment. One-on-one in-depth interviews were conducted for about eight weeks from January 14, 2022 to March 11, 2022. For this study, the TIPS support project was subdivided into four categories: commercialization funds, incubation facilities, capacity building programs, and private investment attraction, and entrepreneurship factors were classified into four categories: innovation, challenge spirit, leadership, and risk-taking. As a result of the in-depth interview, the influence of the TIPS support project on entrepreneurship factors was in the order of challenge spirit, innovation, risk-taking, and leadership. Specifically, it was found that commercialization funds influenced innovation and risk-taking, incubation facilities had a challenge spirit and risk-taking, competency-building programs had a challenge spirit and leadership, and attracting private investment had an influence on innovation and challenge spirit. The implications of this study are that the TIPS support project, a private investment-led technology start-up support program, was introduced in 2013 and as of the end of March 2022, and a report was prepared focusing on visible performance such as private investment performance and employment rate. However, through this study, by analyzing whether the TIPS support project contributed to the cultivation of entrepreneurship for TIPS start-ups, it was found that it had a positive influence not only on quantitative growth but also on qualitative growth.

interrelationship among the characters of the top and the root within a plant was investigated by deviding the roots of the plant into two parts and growing each one in two different environmental conditions, The roots grown on the poor environmental conditions such as over flooding moisture and overdried were less in numbers of root. shorter in root length. and lighter in root weight than those of good growing conditions, It was demonstrated that the roots grown under the poor environmental conditions affected not only the growing of the associated tillers but also the growing of all the tillers within a plant. In comparision with untreated plants. the culm length of treated plants was shortened. and the heading time of them was delayed. The most remarkable yield reduction was appeared at the over flooding moisture treatment. and the next was at the overdried treatment. The ten dency of yield reduction was more severe in sandy soil than that of clay loam.

This study was intended to demonstrate how entrepreneurship education and entrepreneurship affect the entrepreneurial intention, and also to examine whether Deokhu-like behavior, which can be called a personal characteristic, acts as an moderating variable in the relationship between entrepreneurship and entrepreneurial intention. For this study, we conducted an online survey of young people through a research company and collected 231 surveys. The analysis showed that entrepreneurship education had a positive impact on risk-taking and innovativeness, which are factors of entrepreneurship, and again, risk-taking and innovativeness, had a positive impact on entrepreneurial intention. And the mediating effect was also found to be significant. It was also shown that the moderating effect of Deokhu-like behavior on risk-taking and innovativeness was significant. These findings suggest that entrepreneurship education has the effect of enhancing the entrepreneurial intention through the medium of entrepreneurship, and that the entrepreneurial intention can be stronger if a person with Deokhu-like behavior fosters entrepreneurship.
