Tulsi (Ocimum sanctum), commonly known as Holy Basil is a revered herb with a rich history in traditional medicine systems, particularly in Southeast Asia. For its medicinal properties, Tulsi has been regarded as an “Elixir of Life” and has been used to treat various ailments. However, the comprehensive investigation of Tulsi extracts and their potential pharmacological benefits, specifically in relation to antioxidant activity remains limited. Hence, the objective of this study was to evaluate the antioxidant activity of Tulsi leaf and stem extract using various screening methods. We investigate the antioxidant activity exhibited by the extract using three different methods involved the utilization of the total polyphenol content assay, the ferric reducing power assay and 2, 2-diphenyl-1-14 picrylhydrazyl (DPPH) assays. The results revealed that the Tulsi leaf extract (TLE) exhibited significantly higher antioxidant activity when compared to the Tulsi stem extract (TSE) in all the performed assays. The higher content of phenolics in TLE may have contributed to its superior antioxidant activity. The HPLC (high performance liquid chromatography) analysis of TLE revealed the presence of eugenol, active compound for several therapeutic properties. These findings provide an understanding of the bioactive compounds present in Tulsi extracts and their potential antioxidant benefits.

Soybeans are used for various purposes as a major source of protein, carbohydrates, and fat. This study was conducted to investigate the component changes in protein, amino acid, and antioxidant substances with different sowing periods by soybean varieties, as climate warming accelerates in recent years. The content of isoflavone according to early sowing did not differ by sowing period. However, it was confirmed that the content of isoflavone was higher in functional soybean cultivars such as Cheongja-5 having blue color at seed inside, Pungsan and Sowon used soybean sprouts, and Jinyang without fishy smell. There was no significant difference in the changes in protein and amino acid content according to the sowing time by soybean cultivars. The protein and amino acid content by early sowing tended to be lower than that of timely sowing. In most varieties except for some varieties, the content of proline was the highest by early sowing, confirming the presence of stress due to early sowing.

본 연구는 붉나무와 참죽나무 추출물을 이용하여 딸기 흰가루병에 대한 천연 방제제의 방제 효과를 규명하기 위해 수행하였다. 딸기 흰가루병 친환경 방제제 개발을 위해 총 30종의 약용작물 추출물로 흰가루병 방제 효과를 시험한 결과 최종적으로 붉나무와 참죽나무 추출물을 선발하였다. 붉나무와 참죽나무 추출물을 단용 처리 시 방제가는 50~70% 범위로 일반 살균제보다 낮았다. 따라서 흰가루병 방제에 효과가 있다고 보고되고 있는 규산칼륨과 추출물을 혼용 처리하여 실험한 결과 방제 효과가 살균제와 비슷한 수준의 86%로 증대되었다. 규산칼륨과 추출물의 농도에 따른 방제 효과를 확인한 결과, 0.5%의 규산칼륨과 1,000배의 추출물이 적정 농도였다. 살포 횟수에 따른 방제 효과를 규명하기 위해 1회와 2회 처리를 실시한 결과 1회 처리 시 방제 효과가 13~14일로 나타났고, 3~4일 간격으로 2회 살포할 경우 30일 가량의 방제 기간을 가져 1회 처리보다 방제 효과가 더 우수하여 딸기 수확기 살균제 처리를 할 수 없는 기간에 방제가 가능한 것으로 나타났다.

1. 볼리비아 국토 면적의 34.21%는 농경지로 이 중 89.06% 는 목초지다. 볼리비아 전체인구 중 농촌지역 거주민이 30.7% 인데 반해 차코지역은 과반수(약 58%)가 목축업, 작물재배 등에 종사 중으로 농업이 지역경제의 주요 축을 구성한다. 2. 차코는 생태학적으로 식생이 다양하고 생물다양성이 보전된 곳으로 농업 잠재성은 높은 반면 저개발 되어 있고, 원주민의 한정된 공간에서의 무분별한 재래식 방목과 불충분한 식수와 초지 부족, 기후변화로 토양침식, 생태계 파괴가 진행 되고 있다. 3. 산지축산체계는 나무·관목 및 목초의 선별적 간벌을 통해 임간초지를 조성하고 목초를 생산하며 계획적 방목을 통한 지속가능한 축산관리 모델임이 입증됐다. 4. 체계 도입조건으로 자연·물리적 환경(최소 100ha 이상·수자원 접근 가능), 예산운영(4년간 114,000 Bs 고정지출 능력), 기술적용(가축관리 및 식수 수집·저장), 관리능력(축산관리 기본지식·학습의지)이 주요했다. 5. 농업개발협력 시 발생 문제(예산처리지연, 이해당사자 간 소통 미흡, 참여저조)를 해결하기 위해 지속가능한 사업관리체계 및 거버넌스가 구축돼야 한다.

The purpose of this study was to investigate the relationship the quality of life, osteoarthritis and osteoporosis in the Republic of Korea. This study was utilized raw data from the 2010 KCHS. In total, 229,229 individuals participated in the 2010 survey. The final analysis was identified 22,545 individuals who had been diagnosed by a doctor with arthritis or osteoporosis. To identify the relationship between the quality of life - related after treated or treating of arthritis, osteoporosis, A multiple linear regression analysis was performed. Treating group for osteoarthritis of their quality of life has statistically been less than after treated group(B=-.068, p<.001). Treating group for osteoporosis of their quality of life has statistically been less than after treated group(B=-.083, p<.001). Non-treatment group who was diagnosed by doctor, but no treated subject for osteoarthritis of their quality of life has statistically been less than after treated group(B=-.075, p<.001). Non-treatment group that was diagnosed by doctor, but no treated subject for osteoporosis of their quality of life has statistically been less than after treated group(B=-.045, p<.001). Non-treatment group who was diagnosed by doctor, but no treated subject for osteoporosis and arthritis of their quality of life has statistically been less than after treated group(B=-.0121, p<.001). as a result of those data, we understand that the decision maker for treatment has been chosen by quality of life, including pain, mobility activity and so on.

Background : Currently, obesity and adult diseases as a result of sugar intake have been a consistent problem in Korea. Natural sweeteners as sugar substitutes have many advantages over sugar as a small quantity. Therefore, this study was conducted to investigate possibility of industrialization as food additives by using the nature sweetness components of stevia (Stevia rebaudiana Bertoni). Method and Results : Stevia was cultivated in a plastic house. The leaves and stems were harvested at October. They were ground into fine powder using a mill, and were extracted by high temperature and pression extraction method. The extracts were evaporated under vacuum and lyophilized. Three strawberry cultivars of ‘Seolhyang’, ‘Maehyang’, and ‘F22-196’ were cultivated in a plastic house and were harvested from March to May. The fruits harvested were stored at 50℃ until processing. In order to test the processing suitability of stevia extract, the characteristics of the three strawberry varieties (line) were investigated. As a result, the ‘F22-196’ line, which was bred as a processing strawberry, generally contained more antioxidant materials and activity than those of ‘Maehyang’ and ‘Seolhyang’ varieties. Comparing the sugar contents which affects the quality of strawberry jam, the average sugar contents of ‘F22-196’ line was higher than 'Maehyang' and 'Seolhyang' varieties. In the preparation of strawberry jam using ‘F22-196’, strawberry jam was prepared by adding only sugar or stevia extract powder, which was 1/100 of the amount of the sugar in only sugar strawberry jam, to the sensory test. As a result, we identified that sugar jam and stevia jam added stevia extract showed 50 : 50 at the sensory test and stevia jam does not make a difference to the marketing jam at the point of view of general consumers. Conclusion : ‘F22-196’ line represented the best quality for strawberry jam in test caltivars. Stevia powder is judged to be used as a sweetener of sugar substitutes in the production of strawberry jam and processing food.
