  • Consumers are increasingly quality orientated and an understanding of the factors that influence product quality is a prerequisite to the development of programs to produce quality pork to meet market requirements. Pork quality is comprised of many components and is multi-factorial in nature. This review focuses on genetic and environmental influences on muscle color, water holding capacity, and palatability attributes. The impact of genetic factors such as breed variation and the influence of major genes (the Halothane and Rendement Napole genes), as well as relationships between carcass leanness and quality, are considered. In addition, the effect of nutrition, including vitamins and minerals, feeding level, and dietary energy:protein ratio, on pork quality is reviewed. Finally, the impact of diet on fat composition and quality is summarized.

  • A nutritional supplement was developed aiming at correcting the most common nutrient and caloric deficiencies encountered in elderly people (${\geq}60$ years old). The protein source was a mixture of whey protein isolates (WPI) and bovine collagen hydrolysate (BCH) with high nutritional and functional qualities making up 12% of the formulation. The carbohydrate fraction was composed of sucrose, inulin (soluble fiber), and fructo-oligosaccharide (prebiotic). The most commonly deficient essential minerals and vitamins were also included. Acceptance of the product was good according to both an elderly panel and a laboratory panel composing of both sexes and various ages. The stability of the formulations was evaluated and the estimated shelf life at room temperature (ca. $27^{\circ}C$) was approximately 4 months.

  • Pumpkin sweet potato (Ipomoea batas L.) has been known as a traditional remedy and food source, not only in South Korea but worldwide. It is rich in fiber, potassium, vitamin C, and other minerals and vitamins, making it a nutritional food loved by many. showed that pumpkin sweet potato had antioxidant biological effects. The in vitro study showed that both splenocytes and cytokine production byactivated peritoneal macrophages increased when water extracts were supplemented at 100 and 250 μL/mL. Notably, the production of IL-1β, TNF-α, and IFN-γ by splenocytes was significantly increased at 100 μL/mL. The results suggest that supplementation with pumpkin sweet potato (Ipomoea batas L.) water extract may enhance immune function by stimulating splenocyte proliferation and improving cytokine production, activating macrophages in vitro.

  • Nutrition knowledge of mothers who had middle-school studients was investigated using questionnaire about nutrition knowledge and food habit. The results were summerized as follows ; The mean score of nutrition knowledge was 25.3 (out of possible-80-80points), which score was slightly lower than those of other studies. the percentage of perceived knowledge and accuracy of the knowledge were 77.7% and 79.6%, respectively. these scores were influenced by general characteristics such as age, education, occupation, income, food expense. With decreasing age and increasing education level, family income, nutritional knowledge score, the percentage of perceived knowledge and accuracy were significantly getting higher. The levels of both perceived knowledge and accuracy on the necessi쇼 of vitamins and minerals were above 90%. However, the accuracy on protein quality and dietary fiber was below 40%. The better food habit a subject had, the higher was the nutrition knowledge score.

  • Several micronutrients (vitamins and minerals) are required as co-factors in DNA synthesis, DNA repair, DNA methylation and apoptosis. Some notable examples include (a) folic acid and vitamin B12 required for maintenance methylation of DNA and the synthesis of dTTP from dUTP, thus prevent the misincorporation of uracil into DNA, a highly mutagenic and chromosome-breaking event, (b) niacin, is essential in the form of the coenzymes NAD and NADP which act as a substrate for polyADPribose polymerase (PARP), an enzyme thought to facilitate efficient DNA repair and telomere length regulation and (c) zinc, apart from its antioxidant role as a co-factor in Cu/Zn SOD, it is required in its stabilizing role of the DNA-binding domain of p53 (residues 102-292) and thus is essential for apoptotic response to DNA damage.

  • The purpose of this study was to develop and succeed local foods such as Yangte miyuck-gook, Getjango-tang, Boongjango-gook, Sook doenjang-gook, Mulmegi-gook and Mukjang-gook in the Namhae region. To derive standardized recipes; first, a test recipe was prepared based on the information obtained from literature material, personal interviews of Namhae natives, and surveys of restaurant recipes through restaurant owners and chefs in the Namhae area. After that, standardized recipes were made in accordance with the collected data. Then, CAN Program 2.0 was used for the nutritional evaluation. Most of these fish soups contained high percentages of protein, minerals and vitamins. Getjango-tang and boongjango-gook were higher than the other foods in most of nutrition contents, which were particularly good sources of calcium and iron.

  • Accelerated stability testing was performed on the different 7 dosage forms in order to evaluate the influences of the existence of other vitamins, minerals, excipients on the chemical stability of vitamin A in complicated vitamin drug products. The stability results suggested that increasing of storage time and temperature has resulted in increasing the rate of vitamin A decomposition and the shelf lives(t$\sub$90/) under the test decreased as the storage temperature increased.

  • Skin is the first line of defense for protecting our bodies against external perturbations, including ultraviolet (UV) irradiation, mechanical/chemical stress, and bacterial infection. Nutrition is one of many factors required for the maintenance of overall skin health. An impaired nutritional status alters the structural integrity and biological function of skin, resulting in an abnormal skin barrier. In particular, the importance of micronutrients (such as certain vitamins and minerals) for skin health has been highlighted in cell culture, animal, and clinical studies. These micronutrients are employed not only as active compounds in therapeutic agents for treating certain skin diseases, but also as ingredients in cosmetic products. Here, the author describes the barrier function of the skin and the general nutritional requirements for skin health. The goal of this review is to discuss the potential roles and current knowledge of selected micronutrients in skin health and function.

  • Explants of button daisy were screened for their regeneration potential and transient GUS gene expression. Medium containing MS salts minerals and $B_5$ vitamins supplemented with $0.1\;\cal{mg/L}$ BA and $0.1\;\cal{mg/L}$ TDZ showed the best regeneration. Disc florets and receptacles were the most responsive explants in regeneration and transient gene expression respectively. Regenerated plants were successfully rooted and established in the green-house conditions. Infection and co-cultivation of explants with Agrobacterium tumefaciens containing pCAMBIA 1301 resulted in transient GUS foci. Among the different explants, receptacles showed the highest percentage of transient GUS gene expression. Enzymatic and molecular analyses of transformed calli confirmed the integration of GUS gene.

  • Phytic acid (myo-inositol hexaphosphate or IP6) is the major storage form of phosphorus in cereals and legumes, representing 18 to 88% of the total phosphorus. Phytate form of phosphorus is not readily utilized by monogastric animals and this result causes pollution problem by phosporus released in areas of intensive livestock production. The interaction between phytic acid and essential dietary minerals, protein, or vitamins is considered to be one of the primary factors limiting the nutritional values of cereals and legunes in monogastric animals. Attempts have been made to hydrolyze dietary phytic acid by phytases to improve the feed quality and to decrease the amount of phosphorus excreted by animals. Phytase(myo-inositol hexakisphosphate phosphohydrolase) hydrolyzes phytic acid to myo-inositol and phosphoric acid. Two types of phytases are known: 3-phytase (EC 3.1.3.8) and 6-phytase (EC 3.1.3.26), indicating the intial attack to the susceptable phosphoester bond. Because of its great industrial importance, there is ongoing interest in isolating new bacterial strains producing novel and efficient phytases.
