  • Hypertension is characterized by excessive renin-angiotensin system activity, leading to blood vessel constriction. Several synthetic compounds have been developed to inhibit renin and angiotensin-converting enzyme (ACE). These drugs often have adverse side effects, driving the exploration of plant protein-derived peptides as alternative or supplementary treatments. This study assessed the phenolic compound and amino acid content and the antioxidant and antihypertensive activity of 5 South Korean staple crops. Sorghum had the highest phenolic compound content and exhibited the highest antioxidant activity. Millet grains, particularly finger millet (38.86%), showed higher antihypertensive activity than red beans (14.42%) and sorghum (17.16%). Finger millet was found to contain a large proportion of branched-chain, aromatic, and sulfur-containing amino acids, which are associated with ACE inhibition. In particular, cysteine content was positively correlated with ACE inhibition in the crops tested (r=0.696, p<0.01). This study confirmed that the amino acid composition was more correlated with the antihypertensive activity of grains than the phenolic compound content. Finger millet mainly contained amino acids, which have higher ACE inhibitory activity, resulting in the strongest antihypertensive activity. These findings underscore the antihypertensive potential of select crops as plant-based food ingredients, offering insight into their biological functions.

  • The relative difference between Korean rural region and urban region has increased by the rapid urbanization and industrialization since 1960. Therefore it will be important to raise the income of the people living in rural region. So the Korean government established the collective side job area and rural industrial area for the increasing of the non-agricultural income. For this, the touristic resources development is also the another important means of the rural region development. So the purpose of this thesis exists in the presentation of the direction of the touristic resources development in rural region. For this purpose, three representative regions among the Korean rural regions were selected and the case study was accomplished. In this way the rough direction of the touristic resources development in rural region has presented The direction of the development and the conclusion were as follows : 1)Planners must establish the planning with the vision and demand of future than percent condition. 2)Because the urbanization is continued incessantly, the rural region is developed to be the space of resort. 3)The touristic resources development in rural region is contributed to the regional development through the raising interaction of the touristic resources. 4)The rural region is developed to be the space of the Korean rural tradition 5)The grassland os constructed in the mountenous land and the landscape of the Korean national land is changed to be the picturesque landscape. 6)The construction of the traditional artistic products is accomplished to increase the income of the people in rural region.

  • This study was conducted to develop a fast and efficient screening method to determine the quantity of fatty acid in peanut oil for high oleate breeding program. A total of 329 peanut samples were used in this study, 227 of which were considered in the calibration equation development and 102 were utilized for validation, using near infrared reflectance spectroscopy (NIRS). The NIRS equations for all the seven fatty acids had low standard error of calibration (SEC) values, while high R2 values of 0.983 and 0.991 were obtained for oleic and linoleic acids, respectively in the calibration equation. Furthermore, the predicted means of the two main fatty acids in the calibration equation were very similar to the means based on gas chromatography (GC) analysis, ranging from 36.7 to 77.1% for oleic acid and 7.1 to 42.7% for linoleic acid. Based on the standard error of prediction (SEP), bias values, and $R^2$ statistics, the NIRS fatty acid equations were accurately predicted the concentrations of oleic and linoleic acids of the validation sample set. These results suggest that NIRS equations of oleic and linoleic acid can be used as a rapid mass screening method for fatty acid content analysis in peanut breeding program.

  • The purpose of this study is to find a way to improve damaged forest in rural area in terms of both landscape . quality and regulation. Mountain and forest cover 65% of total land in Korea, and the shortage of areas for developing housing, road and facilities made us to use forest area for above purposes. This led various types of damages on the sensitive rural landscape visually and ecologically. There are rules and regulations for decreasing damaging effect by constructions on forest area, but it was not so effective because theses rules focused on quantitative issues only. This study will consist of three phases, 1. analyse landscape damage types by development tendencies in forest area 2. find diminution plan on each damage types 3. set improvement on rules and regulations both qualitatively and quantitatively. This study will meet the goal of improving and managing rural and forest landscape by providing objective standards, rational procedure and amelioration plan.

  • Decrease in Population and graying of rural area by industrialization and urbanization are gone continuously. This makes happened various rural problems and the differential of standard of living with is arising day by day. Government is unfolding rural supporting project to solve continuously these problems. Recent Projects which are choosing not top-down process by government leading but bottom-up process through village inhabitants' participation and expert consultant get positive estimation. But those have difficulties because the support is attained only in the beginning step not continuously and inhabitants' number by graying is decreasing. The Special Economic Zone for Regional Development Policy is new access that regulation can differ according to special quality of each area depending on Localization Age. Through this transfer the competence that can mitigate or reinforce various regulations according to special quality of area in local government. So, back and maintain activation systematically so that each area could be developed specially. The purpose of The Special Economic Zone for Regional Development Policy is the activation of regional economy through development that regional specific character is. And there is characteristic that local government plans and takes the lead in all project contents, government gives regulation benefit by appointing the special economic zone and do not support finance and various tax remissions. Through investigation of such new policy, I wish to recognize what long-term plan and method could be possible to success rural activation continuously.

  • Plant reproduction associated with crop yields is highly vulnerable to global climate change components such as high and cold temperatures. The objectives of this study were to determine the effects of season-high exposure to temperature treatments in pollen morphology on Adzuki bean (V. angularis) and Mung bean (V. radiate). V. angularis and V. radiata were treated at high temperatures in the high temperature gradient greenhouse designed to cause temperature deviation. The pollen shapes treated at high temperature were compared by an electron scanning microscope. As a result, it was confirmed that the number of abnormal pollens morphology at high temperature was the least in V. radiata, and V. angularis was vulnerable to high temperatures. Also, it was found that the number of abnormal pollen morphology atT4 (Con +5~6℃) varied according to the cultivars of V. angularis. Therefore, the differences in Vigna species or cultivars with thermo-tolerance in pollen morphology to high temperature are projected to occur in the changeable future climate.

  • 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.
