본 연구는 아동양육시설에서 아동을 양육하는 생활지도원들의 양육에 관한 자신감을 높이 고 스트레스 완화 및 정서조절능력에 도움을 주고자 양육기능강화 프로그램을 구성하고 그 효과를 검증하고자 한다. 이를 위해 생활지도원 30명은 중재집단과 통제집단에 각 15명씩 배 정하였다. 중재집단에 포함된 생활지도원은 주 1회, 6회기로 구성된 양육기능강화 프로그램에 참여하였고, 통제집단에는 아무런 처치를 하지 않았다. 조사도구는 요구도 조사를 위한 질문과 프로그램의 효과검증을 위한 생활지도원의 양육효능감, 양육스트레스 및 정서조절능력으로 구성되며, 모든 척도는 자기보고로 평가되었다. 프로그램 전후에 각 집단별 생활지도원의 양육 효능감, 양육스트레스 및 정서조절능력을 조사함으로써, 각 변인들의 사전-사후 조사 간 차이 를 비교하였다. 그 결과, 중재집단의 경우 생활지도원의 양육효능감과 정서조절능력은 긍정적 으로 향상되었고, 양육스트레스는 감소한 것으로 나타났다. 반면, 통제집단의 경우는 양육효능 감은 긍정적으로 변화된 반면, 양육스트레스나 정서조절능력에서의 변화는 보이지 않았다. 본 연구를 통해 양육기능강화 프로그램이 생활지도원의 심리적 안정감과 더불어, 아동을 양육하 는 능력에서 긍정적인 변화가 있음을 확인하였다.

Composition of isoflavone in cotyledon and hypocotyl of soybean were detected using HPLC. Optimum conditions for extracting isoflavone from hypocotyl were studied as well. Contents of isoflavone in soybean cotyledon and hypocotyl were 482.5 mg 100 g-1

Purpose - Manufacturers in uncertain environments need to depend on governance mechanisms to reduce the inherent risk in these environments. However, few studies have examined which governance mechanisms a given manufacturers will develop in uncertain environments for managing the relationships with its vertical partner. This study explores how different governance mechanisms function under uncertain environmental circumstances. We also try to investigate the contextual effect of interfirm benevolence as moderator. Research design, data, and methodology - This research provide the conceptual framework of interfirm benevolence on which this research's propositions are predicted. The theoretical background for environmental uncertainty, governance mechanisms and interfirm benevolence will be discussed. Results - The expected results are as follows. Manufacturers in an uncertain environments rely on different governance mechanisms under conditions of high and low interfirm benevolence. In terms of role of interfirm benevolence, interfirm benevolence provides a better understanding of how governance mechanisms can develop in an uncertain supply markets. Conclusions - This research suggests several theoretical and practical implications between channel partners, particularly, this research offers that interfirm benevolence is a crucial competitive factor under environmental uncertainty situation. In future studies, it is necessary to investigate the effect of each governance mechanism structure on performance in an uncertain environment and various level of interfirm benevolence.

Endocytosis of the Notch ligand, DeltaD, by mind bomb1 is indispensable for activation of Notch in cell fate determination, proliferation, and differentiation during zebrafish neurogenesis. Loss of mind bomb1 activity as an E3 Ubiquitin ligase causes the accumulation of deltaD at the plasma membrane and results in the ectopic neurogenic phenotype by activation of Notch in early zebrafish embryogenesis. However, the regulatory mechanism of deltaD during neurogenesis is not identified yet. This study aims to analyze the pathway of mib1 and deltaD after endocytosis in vivo during zebrafish embryogenesis. Mind bomb1 and deltaD are co-localized into autophagosome and mutant form of mind bomb1 fails to cargo deltaD into autophagosomes. These findings suggest that mind bomb I mediates deltaD regulation by autophagy in an ubiquitin-dependent manner during zebrafish embryogenesis.

Over the past few decades Miscanthus has been studied as a potential bioenergy crop in Europe but not much been studied in Korea although Korea has many native Miscanthus species and genetic resources. Because of their features, such as low demands of fertilizers and other agrochemicals, high water use efficiency and high productivity, Miscanthus can be cultivated in marginal lands. However, it is not known how Miscanthus can survive in saline soil and what extent Miscanthus can tolerate salt stress, one of main abiotic stresses in reclaimed lands or dry climates. Therefore, this study was conducted to investigate physiological response of Miscanthus species to salt stress and thus to establish a salt stress threshold. Miscanthus sinensis and M. sacchariflorus showed similar responses to salt stress. Chlorophyll contents, photosynthesis and plant growth were all significantly affected by salt stress. Both species were completely killed at > 100 mM NaCl. The GR50 values estimated by non-linear regression analysis with the logistic model were 116.2 mM and 63.1 mM for M. sinensis and M. sacchariflorus, respectively. These GR50 values can be used as their thresholds of salt stress. Further studies will be conducted to screen salt-tolerant Miscanthus genotypes.
