<P>Sophorae Radix (<I>Sophora flavescens </I>Aiton) has long been used in traditional medicine in East Asia due to the various biological activities of its secondary metabolites. Endogenous contents of phenolic compounds (phenolic acid, flavonol, and isoflavone) and the main bioactive compounds of Sophorae Radix were analyzed based on the qualitative HPLC analysis and evaluated in different organs and at different developmental stages. In total, 11 compounds were detected, and the composition of the roots and aerial parts (leaves, stems, and flowers) was significantly different. trans-Cinnamic acid and<I> p</I>-coumaric acid were observed only in the aerial parts. Large amounts of rutin and maackiain were detected in the roots. Four phenolic acid compounds (benzoic acid, caffeic acid, ferulic acid, and chlorogenic acid) and four flavonol compounds (kaempferol, catechin hydrate, epicatechin, and rutin) were higher in aerial parts than in roots. To identify putative genes involved in phenolic compounds biosynthesis, a total of 41 transcripts were investigated. Expression patterns of these selected genes, as well as the multiple isoforms for the genes, varied by organ and developmental stage, implying that they are involved in the biosynthesis of various phenolic compounds both spatially and temporally.</P>

‘Dahomi’, a new sweetpotato variety, was developed for table use by the sweetpotato breeding team of Bioenergy Crop Research Institute, National Institute of Crop Science (NICS), RDA in 2012. This variety was derived from the cross between ‘Muan4’ and ‘Jinhongmi’ in 2005. The seedling and line selections were performed from 2007 to 2008, preliminary and advanced yield trials were carried out from 2009 to 2010, and the regional yield trials was conducted at five locations from 2011 to 2012 and it was named as ‘Dahomi’. This variety has three or five lobes leaf, green leaf, stem, and petiole. Storage root of ‘Dahomi’ was elliptic, red skin, light orange flesh. This variety is resistant to fusarium wilt, but susceptible to root-knot nematode. Texture of steamed storage root was intermediate, and degree Brix of steamed storage root was 24.8 °Brix. The total sugar content of raw and steamed storage root was 9.7, 32.0/100 dry weight (g), respectively, which was higher than that of ‘Yulmi. Storage root yield of ‘Dahomi’ was 26.3 MT/ha under the early seasonal cultivation, which was 52% higher than that of ‘Yulmi’. Storage root yield of ‘Dahomi’ was 21.9 MT/ha under the optimum and late seasonal cultivation, which was 35% higher than that of ‘Yulmi’. The number of storage roots over 50 g per plant was 2.8 and the average weight of storage root was 138 g under the optimum and late seasonal cultivation.

본 연구에서는 감정노동이 심리적 탈진에 미치는 영향을 살펴보고, 감정노동과 심리적 탈진의 관계에서 정서지능의 조절효과를 확인하고자 하였다. 이를 위해 경찰공 무원 450명을 대상으로 2018년 9월 25일부터 10월 10일까지 설문을 실시하였고, 누락이 되거나 불성실하게 응답한 25부를 제외한 4251부를 최종 분석에 사용하였으며, 분석방법으로는 spss 21.0을 사용하여 기술통계 및 상관 분석, 위계적 회귀분석을 통해 감정노동이 심리적 탈진에 미치는 영향과 정서지능의 상호작용 효과를 검증하였 다. 그 결과 감정노동은 심리적 탈진에 유의한 정적인 영향을 미치는 것으로 나타났 으며, 정서지능은 감정노동과 심리적 탈진 간의 관계에서 부적으로 조절하는 것으로 나타났다. 이러한 결과는 감정노동을 강하게 경험할수록 심리적 탈진의 수준이 높아 진다는 것을 나타내며, 스트레스 상황에서도 정서를 적절하게 조절하여 합리적인 사고를 가능하게 하는 정서지능은 감정노동이 심리적 탈진에 미치는 영향 관계에서 조절 역할을 하는 것으로 검정되었다는 의의를 가진다. 이러한 결과를 바탕으로 본 연구의 함의와 함께 제한점, 그리고 후속연구를 위한 제언을 논의하였다. The purpose of this study was to examine the effects of emotional labor on psychological burnout and to confirm the moderating effect of emotional intelligence on the relationship between emotional labor and psychological burnout. For this purpose, we surveyed 425 police officers about emotional labor, psychological burning, and emotional intelligence. The hierarchical regression analysis was used to verify the effect of emotional labor on psychological burnout and the interaction effect of emotional intelligence. As a result, emotional labor showed a significant positive effect on psychological burnout, and emotional intelligence showed negative control in the relationship between emotional labor and psychological burnout. These results indicate that the higher the level of emotional labor experience, the higher the level of psychological burnout. Emotional intelligence, which enables rational thinking by appropriately controlling emotions even under stress conditions, plays a moderating role in affecting emotional labor This means that it has been confirmed that Based on these results, implications of this study, limitations, and suggestions for subsequent research were discussed.

In 2019, ‘Bodeuremi’ was developed as a high-yielding sweetpotato variety with good palatability. It was derived from a cross between ‘MI2006-58-02’ with high yield and ‘Beniharuka’ (IT309504) with good palatability. The storage roots of ‘Bodeuremi’ have a red skin, light orange flesh, and an ovate shape. When steamed, ‘Bodeuremi’ storage roots exhibit a moist texture and are more tender than those of the check variety ‘Pungwonmi’. The sugar content of steamed ‘Bodeuremi’ storage roots was 33.4 mg/100 g dw, which was 6.0% higher than that of ‘Pungwonmi’. The marketable yield of ‘Bodeuremi’ storage roots was 30.3 MT/ha in the early season culture, which was 4.5% higher than that of ‘Pungwonmi’ with high yield in the early season culture. ‘Bodeuremi’ is resistant to root-knot nematode and moderately resistant to Fusarium wilt. ‘Bodeuremi’ is expected to contribute to increased income of sweetpotato growers as it has high cultivation stability and can be shipped at a time when the market price is high owing to its high yield in the early cultivation.
