The effect of marination with black currant juice (BCJ) was investigated for their effects on meat quality and content of biogenic amines (BAs) [putrescine (PUT), cadaverine (CAD), histamine (HIM), tyramine (TYM), and spermidine (SPD)] in pork belly during storage at 9℃. BCJ was shown to have antibacterial activities against Escherichia coli and Pseudomonas aeruginosa. Additionally, the pH of pork belly marinated with BCJ (PBB) was significantly lower than that of raw pork belly (RPB) during storage. No significant difference in microorganisms between RPB and PBB was observed at day 0 of storage. However, at days 5 and 10 of storage, volatile basic nitrogen (VBN) was significantly decreased in PBB compared to RPB, and PBB also demonstrated significantly lower numbers of bacteria associated with spoilage (Enterobacteriaceae and Pseudomonas spp.) at these time-points. PBB was also associated with significantly reduced formation of BAs (PUT, CAD, TYM, and total BAs) compared to RPB at days 5 and 10 of storage. These results indicated that BCJ can be regarded as a natural additive for improving meat quality by preventing increased pH, VBN, bacterial spoilage, and inhibiting BAs formation during refrigerated storage.

위암은 최근에 균일한 성격의 단일 질환이 아니라, 매우 이질적인 질환으로 인식되고 있다. 수술이 불가능한 진행성 또는 전이성 위암의 경우 일반적으로 완치가 불가능하며 항암치료를 하지 않는 경우 중앙 생존기간이 3-6개월 정도로 알려져 있다. 따라서 항암치료를 하는 경우가 최선의 지지 치료에 비하여 삶의 질이나 생명연장의 측면에서 우월함을 이미 여러 연구를 통해서 확인되고 있다. 지난 기간 동안 다양한 항암치료가 진행성 위암의 치료에 적용되었고, 최근에 여러 표적 치료와 면역치료가 도입되고 있으나, 여전히 다른 암종에 비하여 진행성 위암환자에서는 현저한 생명연장은 아직 저조하고 답보 상태에 있다. 그러나 향후 위암의 분자생물학적인 특성이 자세히 알려지면서 이러한 어려움들은 극복될 것으로 기대된다.

Sustainable meal management at home will be affected by the lifestyle of the housewife. This study examined the lifestyle of middle aged women and identified their practice levels of sustainable meal management at home. A total of 438 women, aged 35 to 59, managing the family's dietary life at home and living in Seoul, Gyeonggi Province, Daejeon, and Chonnan area participated in the survey. The middle aged women showed a higher performance level of hygiene-oriented (4.15) and health-oriented dietary life (3.59), but a less convenience-oriented dietary life (2.57). Based on their lifestyle, 3 clusters were extracted: Low-interest dietary life meal manager, health and quality pursuit meal manager, and convenience and eating-out pursuit active meal manager. Among them, the cluster of health and quality pursuit meal manager showed the highest sustainable practices in 7 dimensions of sustainable practices in the home except for the saving practices (p<0.001). The criteria suggested from the study can be applicable to the guidelines of sustainable meal management at home. The study can also be helpful for educators to identify the education themes for improving housewife's sustainable meal practices, having different lifestyle and sustainable meal practices.

Treatment for breast cancer produces side effects that diminish functional capacity and quality of life (QOL) among survivors. Tai Chi is a moderate form of exercise that may improve functional capacity, physical activity and oxidative stress. The purpose of this study was to evaluate the effects of regular Tai Chi exercise on malondialdehyde (MDA), SOD and physical fitness (muscle strength, flexibility, flexion, extension, adduction, and abduction). Forty obese women were recruited from a public health center and divided into control (CON: n=20) and trained (EXP: n=20) groups. The Tai Chi exercise group participated in a 12-week (4 times/week) training program. Data were analyzed with T-test. MDA, SOD and physical fitness (muscle strength, flexibility, flexion, extension, adduction, and abduction) were evaluated before and after the Tai Chi program in both groups. There were significant improvements in shoulder flexibility, flexion, extension, abduction, and adduction. However, there was no improvement in muscle strength. There were also significant improvements in MDA and SOD. Based on these results, Tai Chi exercise has been shown to stimulate endogenous antioxidant enzymes and reduce oxidative damage markers. and also be effective in improving physical fitness and QOL. Further study is needed in this area.

This study investigated the quality of noodles containing different amounts of collagen powder. Noodles were prepared at ratios of 1, 3, 5 and 7% collagen power based on flour weight. The water binding capacity of the collagen powder was higher than that of flour. The rate of weight increase and volume increase of the noodles as well as the pH and turbidity of the soups were significantly increased with increasing amounts of collagen powder. The noodles showed decreased L and a values, and increased b values with increasing collagen powder in the flour composite. Hardness, springiness and chewiness of cooked noodles increased significantly with the increase in collagen powder content. cohesiveness and brittleness decreased with increasing amounts of added collagen powder. DPPH radical scavenging activity was improved significantly the addition of the collagen powder. Finally sensory evaluation results indicated that the noodles containing 1, 3% collagen powder had higher quality as compared to the other samples. Overall the results suggest that collagen powder is effective for improving the appearance and texture of noodles.

Powders prepared from three different varieties of Korean ginseng (white, red and black) are consumed daily by many Koreans as a functional food material. These variants exert a variety of physiological effects. The principal objective of this study was to evaluate the quality characteristics of Yanggaeng prepared with three different types of ginseng powder. We conducted tests for ginsenosides content, Hunter's color values, mechanical characteristics, and sensory evaluation analysis. The ginsenosides of black ginseng were higher than those of white and red ginseng. The lightness of the black ginseng Yanggaeng was significantly less than the white, red, and control samples (p<0.05). We noted significant differences in Hunter's a and b values. With regard to the mechanical properties of the samples, we noted significant differences in gumminess (p<0.05), but no differences in hardness, springiness, chewiness, and cohesiveness were detected. The results of sensory evaluation showed that there were significant differences in the color, flavor, and overall quality of the samples (p<0.05), but there were no significant differences in taste and texture. Overall, red ginseng Yanggaeng appeared to have the most commercial value for improving the Yanggaeng product.

The United Kingdom is known for the quality of its qualifications. There is a strict quality system with reputable bodies responsible for ensuring that high quality standards are met. In order for new qualifications to be accredited, they must meet all the requirements set out in the regulations for the quality and informatization of Education. The crucial role of the Agency for Quality Assurance of Higher Education (QAA) in the UK for creating high-quality management of higher education institutions is revealed, the influence of informatization tools on its effective mechanism as an independent entity is shown, and positive experience for the educational sector is highlighted. While the universities themselves are responsible for reviewing educational programs at the subject level, the QAA review focuses on verifying internal quality assurance, as well as systems and improvement strategies. The QAA uses a peer review process in which teams mostly consist of academic staff from other institutions to assess the quality of the institution's education. In Scotland, the team also includes an international reviewer. The student is also a member of the Scottish teams. In the UK, attention is paid to providing a cohort of experienced reviewers who can conduct high-quality monitoring and help with advice on improving education. All reviewers must complete training and have permission to participate in the review of educational programs. There are selected committees that are members of the QAA council, each of which is headed by a member of the Council or an independent person approved by the Council. Attention is drawn to the main areas of the QAA's work in the framework of environmental, social and corporate governance.

Organic farming systems based on ecological concepts have the potential to produce sustainable crop yields with no decline in soil and environmental qualities. Recent expansion of sustainable agricultural systems, including organic farming, has brought about need for development of sustainable farming systems based on value judgments for key properties of importance for farming. Chemical and microbiological properties were chosen as indicators of soil quality and measured at soil depth intervals of 5-20 and 20-35 cm in conventional and organic-based apple orchards located in Yeongchun, Gyeongbuk. The orchards were two adjacent fields to ensure the same pedological conditions except management system. Soil pH in organic farming was around 7.5, whereas below 6.0 in conventional farming. Organic farming resulted in significant increases in organic matter and Kjeldahl-N contents compared to those found with conventional management. Microbial populations, biomass C, and enzyme activities (except acid phosphatase) in apple orchard soil of organic farming were higher than those found in conventional farming. Higher microbial quotient ($C_{mic}/C_{org}$ ratio) and lower microbial metabolic quotient for $CO_2(qCO_2)$ in organic farming confirmed that organic farming better conserves soil organic carbon. Biological soil quality indicators showed significant positive correlations with soil organic matter content. These results indicate organic-based farming positively affected soil organic matter content, thus improving soil chemical and biological qualities.
