The purpose of this study was to analyze the physicochemical properties by mixing ratio of soybean and peanut protein to secure basic data for developing alternative protein foods. As a result of analyzing the protein molecular weight pattern, it was confirmed that the specific molecular weight was affected by the soybean and peanut protein mixture. The content of glutamic acid, aspartic acid, arginine, glycine, serine, alanine, and tyrosine among nonessential amino acids was higher as the mixing ratio of peanut protein to soy protein was higher. However, the higher the peanut protein mixing ratio, the lower the water absorption capacity. Based on the results of this study, further studies, such as selecting soybean and peanut cultivars for determining the optimal mixing ratio of soybean and peanut protein and processing methods to improve physical properties, are necessary

본 연구는 우리나라 공직자의 교육 훈련이 조직성과에 미치는 영향에 대해서 실증분석하였다. 이를 위 해 공직자의 교육 훈련, 업무 자율성, 업무수행역량, 직무 만족과 네 가지 변수로 구분하여 이를 정부 중앙·지방부처의 조직성과에 대해서 상관관계를 검증하였다. 분석대상은 한국행정연구원에서 조사한 2018 년 공직생활실태조사와 공공데이터 포털에서 2018년 “공직생활실태조사” 데이터를 습득했고 이를 분석에 활용했다. 또한, 연구의 실증분석 대상으로는 46개 중앙부처와 17개 광역자치단체에 속해 있는 일반직 공무원을 대상으로 진행했다. 분석 결과 공직자의 교육 훈련은 업무수행역량과 업무 자율성이 정(+)의 관계에 대해서 가설을 검증한 결과 공직자의 교육 훈련이 업무수행역량과 업무 자율성에 영향을 미치는 것으로 나타났다. 또한, 공직자의 업무수행역량과 업무 자율성이 직무 만족에 정(+)의 영향을 주는 것으로 확인되었다. 마지막으로 공직자의 직무 만족은 조직성과에 정(+)의 영향을 주는 것으로 확인되었다. 이는 연구자가 상정한 가설이 모두 지지가 되었고, 그 결과로 그간 상대적으로 부족했던 공직자의 교육 훈련 연구를 확장했다는 의미가 있는 동시에 업무 자율성과 업무수행역량에 대한 변수들이 직무 만족과 조직 성과에 변수와의 관계를 설명하는데 활용될 수 있다. 본 연구는 공직자의 교육 훈련이 업무 자율성과, 업무수행역량이 개인, 조직 차원서 영향을 주고 이는 곧 국가 차원으로 확산할 것으로 가정하여 분석하였으나 기존 자료에 한계가 있었고 이에 대해서는 실질적으로 분석이 이루어지지 않았다. 향후 연구에서는 공직자의 교육 훈련이 개인과 조직 차원에서 국가 차원으로 전이되는 구성 요소를 찾고 어떻게 영향을 미치는지 분석하는 것이 향후 연구 방향이라 할 수 있다.

We investigated the physicochemical properties of brown rice by cultivar to select cultivar suitable for making brown rice porridge. The moisture content of the brown rice ranged from 8.79~11.78% with the highest varieties being ‘Geonyangmi’. The crude ash and crude lipid content ranged from 1.02~1.65% and 1.65~3.26%, while the rest were similar except for ‘Daebo’. Crude protein also had the lowest ‘Daebo’ and generally glutinous rice showed higher crude protein content than common rice. The hardness showed that ‘Seolgaeng’ and ‘Keunnun’ were the lowest, and ‘Haiami’ was the highest. In the RVA analysis, the setback was in the range －80.61~22.44 and was low in the order of ‘Wolbaek’, ‘Baekjinju'', and ‘Dongjinchal’. As a result of water binding capacity (WBC) measurement, ‘Sindongjin’, ‘Geonyang’ and ‘Samkwang’, were high in common rice, and ‘Dongjinchal’ and ‘Hwaseonchal’ were high in glutinous rice. Generally, solubility and swelling power in common rice was found to be lower than in glutinous rice. As a result, ‘Samkwang’ is considered suitable for brown rice porridge production because of high WBC, breakdown, and low setback.

The purpose of this study was to investigate antioxidant characteristics and anti-adipogenic effects of colored rice and brown rice extracts in 3T3-L1 adipocyte depending on cultivar (Josaengheugchal, Heugjinmi, Hongjinju, Geongganghongmi, Seolgaeng, Milyang 320, Sindongjin, Baegjinju). Colored rice and brown rice was extracted with 100% ethanol, followed by the analysis of polyphenol, flavonoid, anthocyanin, antioxidant, and anti-adipogenic activity. Total polyphenol and flavonoid content ranged from 6.86~314.08 mg GAE/g and 1.47~56.88 mg CE/g the highest total polyphenol and flavonoid content was observed in Heugjinmi cultivar. Anthocyanin composition was analyzed by HPLC, cyanidin-3-gluoside and peonidin-3-glucoside was found in black rice including Josaengheugchal and Heugjinmi. Also, the ABTS and DPPH radical scavenging activity of colored rice cultivars was higher than that of brown rice cultivars, the highest ABTS radical scavenging activity also was observed in Heugjinmi (128.20 mg TE/g). The anti-adipogenic effects of colored rice and brown rice extracts on differentiation of 3T3-L1 preadipocytes evaluated that extracts of Heugjinmi cultivar significantly reduced intracellular lipid accumulation. These results provide valuable information for the use of Korean colored rice cultivar as a functional food materials relative to anti-obesity.

The purpose of this study was to investigate the inhibitory effect of enzyme activity and anti-proliferation of human cancer cell lines (HCT 116, NCI-H460 and MCF-7) of peanut skin depending on cultivars (Arachis hypogaea L. cv. K-Ol, cv. Sinpalkwang, cv. Daan, cv. Heuksaeng) and extraction solvent. Peanut skin was extracted with 80% ethanol, 80% methanol, 80% acetone, and distilled water, followed by analysis of the enzyme inhibitory activity and anticancer activity. Methanol extract of Daan cultivar most effectively inhibited α-gluosidase (65.08%, 0.025 mg/mL), tyrosinase (82.49%, 2 mg/mL) and ACE (73.61%, 10 mg/mL). The inhibitory effect of peanut skin extracts on colon cancer cell (HCT-116), lung cancer cell (NCI-H460) and breast cancer cell (MCF-7) growth were investigate using MTT assay. The highest anti-proliferation of cancer cell line of peanut skin extracts was observed in the methanol extract of Daan cultivar. The cell viability on HCT 116, NCI-H460 and MCF-7 cell lines of methanol extracts from peanut skin of Daan cultivar was 48.13%, 41.03%, and 36.02% at 200 μg/mL, respectively. These results suggest that peanut skin extracts may mediate physiological activity, and provide valuable information for the use of peanut byproduct as a functional food material.
