Angelica keiskei, a perennial herb from Apiaceae family, has been reported to improve diabetes, inhibit thrombosis, alleviate dyslipidemia, and prevent type 2 diabetes, obesity, and atherosclerosis. In this study, the protective effects of A. keiskei extract (AKE) against tumor necrosis factor-alpha (TNF-α)-induced oxidative stress and vascular inflammation in human umbilical vein endothelial cells (HUVECs) were investigated through cell viability analysis, antioxidant enzyme analysis, western blotting, and immunofluorescence staining. The results demonstrated that pretreatment of Angelica keiskei with AKE significantly inhibited the expression of key adhesion molecules such as E-selectin, ICAM-1 and VCAM-1 induced by TNF-α. AKE also showed a substantial reduction in intracellular reactive oxygen species levels and an increase in antioxidant enzyme activity, indicating potential antioxidant capabilities. This study further explained that AKE interfered with the nuclear factor-kappa B (NF-κB) pathway by inhibiting phosphorylation of IκBα and NF-κB, thereby preventing nuclear translocation. Additionally, AKE selectively inhibited the activation of c-Jun N-terminal kinase (JNK) within the mitogen-activated protein kinase (MAPK) pathway, revealing a specific action mechanism. These findings collectively suggest that AKE possesses multi-faceted protective properties, making it a potential therapeutic agent for inflammatory conditions and early atherosclerosis.

The percentages of sperm motility and normal acrosome on the liquid boar semen diluted and preserved at $4^{\circ}C$ with lactose hydrate, egg yolk and N-acetyl-D-glucosamine (LEN) diluent were significant differences according to preservation day and incubation time, respectively. The sperm motility steadily declined from 96.9% at 0.5 h incubation to 78.8% at 6 h incubation at 1 day of preservation. However, the sperm motility rapidly declined after 4 day of preservation during incubation. The normal acrosome steadily declined from 93.3% at 0.5 h incubation to 73.8% at 6 h incubation at 1 day of preservation. However, the normal acrosome rapidly declined after 3 day of preservation during incubation. The rates of sperm penetration and polyspermy were higher in 5 and $10{\times}10^6$ sperm/ml than in 0.2 and $1{\times}10^6$ sperm/ml. Mean numbers of sperm in penetrated oocyte were highest in $10{\times}10^6$ sperm/ml compared with other sperm concentrations. The rates of blastocysts from the cleaved oocytes (2-4 cell stage) were highest in $1{\times}10^6$sperm/ml compared with other sperm concentrations. In conclusion, we found out that liquid boar sperm stored at $4^{\circ}C$ could be used for in vitro fertilization of pig oocytes matured in vitro. Also, we recommend $1{\times}10^6$sperm/ml concentration for in vitro fertilization of pig oocytes.

매실주의 숙성 중 에틸카바메이트의 발생을 알아보고자 일반 가정에서 담그는 방식으로 매실주와 복분자주를 담아 저장하면서 발생량을 측정하였다. 매실주는 매실과 설탕 및 $19.5^{\circ}{\sim}35^{\circ}$ 담금주의 담금비를 달리하여 담아, 15일부터 180일까지 15~30일 간격으로 에틸카바메이트의 함량을 분석한 결과 숙성 90일 까지 매실을 설탕만으로 숙성한 경우와 복분자주에서 에틸카바메이트는 발생하지 않았으나 매실의 알코올의 농도가 높을수록 에틸카바메이트의 생성량이 증가하였다. 매실과 담금주의 비율을 달리한 결과, 매실보다는 알코올 함량이 에틸카바메이트 발생에 더 큰 영향을 미치는 것을 확인하였으며 120~150일 숙성기간이 지나면서 에틸카바메이트 발생량은 점차 감소하는 경향을 보였으나 90일 숙성 후 여과처리 하였을 경우 여과하지 않았을 경우보다 180일까지 2배가량 높은 에틸카바메이트가 발생하였으나 이들 모두 안전한 수준이었다.

Traditional cuisine reflects cooking traditions shaped by political, economic, social, cultural, and environmental conditions characterized by authenticity and uniqueness. Traditional food is not only a part of our cultural heritage but also a knowledge resource. Application of food science and technology in Korean traditional foods was reviewed from six points of view, including food preservation, fermentation, changes in food materials, utilization of food functionality, and packaging and development of cooking appliances. Books from disparate times were chosen in order to cover a wide range of materials from the past to the present. Food preservation and fermentation techniques were applied to various food materials. Combination of science and skills contributes to the accessibility of diverse food materials and better quality foods. Koreans use assorted and resilient plants, which have an abundance of functional substances such as food materials. Among cooking appliances, microwave oven and refrigerator are the most innovative products with huge influences on food eating patterns as well as lifestyle. Packaging effectively reduces post-harvest preservation losses, and better packaging has technical improvements for storage and distribution. Kimchi was chosen as an example in order to study technology from the past to the present. Availability of Kimchi cabbage, enrichment of functional ingredients, identification of useful microbial species, standardization of recipe for commercialization, prevention of texture softening, introduction of salted Kimchi cabbage and Kimchi refrigerators, and packaging were reviewed. The future of traditional foods in the market will be competitive. First, traditional foods market should be maintained to protect the diversity of food materials. Secondly, tailored foods for individuals should be considered using foods with functional properties. Information on health benefits would provide insights into health and traditional food products. Third, speedy transfer of new technology to the traditional food industry is needed to ensure food quality production and new opportunities in the market. Fourth, safety of traditional foods should be ensured without sacrificing the essential characteristics of culturally important foods. Improvement of logistics, distribution, and facility should be carried out. As demand for convenience foods increases, traditional foods should be developed into products.

This study aims to provide an overview of the research on the chemical composition, nutritional value, biological activities, and potential applications of Camellia oleifera seeds. Camellia oleifera Abel. (Theaceae) is a type of woody plant found in various regions, including China, Japan, India, and Southeast Asia. This plant is highly valued for its cooking oil, as the oil extracted from its seeds contains many unsaturated fatty acids (90%), mainly oleic acid (80%), and various biologically active compounds. Oil derived from C. oleifera seeds has been shown to possess numerous health benefits, such as reducing low-density lipoproteins cholesterol levels, preventing cardiovascular diseases and cancer, and regulating blood pressure. Apart from its oil, the seeds of C. oleifera also contain remarkable biological compounds that offer additional health advantages. Despite these promising attributes, C. oleifera has yet to be widely recognized as a potential source of raw materials for pharmaceutical purposes. This lack of popularity and awareness has hindered further exploration of its pharmaceutical benefits and other uses. Through this article, we hope everyone can better understand this plant and have more practical applications in the future.

Quality changes of Korean native-bee honey were investigated during processing and preseration at different temperature. There were no changes of HMF(Hydroxy methyl furfural) and proline contents, color and diastase activity in Korean native-bee honey, when the honey separated from honey combs at 20$^{\circ}C$ and 40$^{\circ}C$. However, at 50 and 80$^{\circ}C$, browning of Korean native-bee honey was shown, HMF content was increased rapidly and proline content and diastase activity were decreased. There were no changes of chemical composition in Korean native-bee honey during storage at 4$^{\circ}C$ for 6 months. But color was darken and HMF content was increased slowly in Korean native-bee honey during storage at 20$^{\circ}C$. During storage at 30$^{\circ}C$ and 40$^{\circ}C$, HMF content was increased highly, proline content, diastase activity and total acidity was decreased rapidly. It is recommended that Korean native-bee honey is separated from honey comb and purified at less than 40$^{\circ}C$ and stored at 4$^{\circ}C$ through 20$^{\circ}C$.
