Considering that the world population is expected to total 9 billion by 2050, it will clearly be necessary to sustain and even accelerate the rate of improvement in crop productivity. In the 21st century, we now face another, perhaps more devastating, environmental threat, namely climate change, which could cause irreversible damage to agricultural ecosystem and loss of production potential. Enhancing intrinsic yield, plant abiotic stress tolerance, and pest and pathogen resistance through agricultural biotechnology will be a critical part of feeding, clothing, and providing energy for the human population, and overcoming climate change. Development and commercialization of genetically engineered crops have significantly contributed to increase of crop yield and farmer's income, decrease of environmental impact associated with herbicide and insecticide, and to reduction of greenhouse gas emissions from this cropping area. Advances in plant genomics, proteomics and system biology have offered an unprecedented opportunities to identify genes, pathways and networks that control agricultural important traits. Because such advances will provide further details and complete understanding of interaction of plant systems and environmental variables, biotechnology is likely to be the most prominent part of the next generation of successful agricultural industry. In this article, we review the prospects for modification of agricultural target traits by genetic engineering, including enhancement of photosynthesis, abiotic stress tolerance, and pest and pathogen resistance associated with such opportunities and challenges under climate change.

Food consumption pattern changes, including a decrease in rice consumption and increasing demand for fresh vegetables, along with declining food self-sufficiency rate, more importance is being placed on agricultural industry within Korea. Taking these changes into consideration, there is an increasing necessity for managing upland fields on agricultural sector to revitalize agricultural land use. Therefore, in this study, upland use type was classified into agricultural economic, environmental conservation, and rural social frames. The purpose of this study was to suggest upland use plan with farm manager registration information and spatial data. As results of this analysis, the mean area of agricultural economic frame in Haenam (16.47 ha) was found to be wider than Muan (3.17 ha), and scale improvement zones (54 zones) were located in only Haenam. In case of environmental conservation frame, there's no zone of scenic agriculture land in both study areas, but landuse transition zones were located in Muan (278 zones) and Haenam (604 zones). Agro-healing zones of rural social frame were 1,018 zones in Muan and 1,588 zones in Haenam and kitchen garden sites were 342 zones in Muan and 370 zones in Haenam. These results could be used when we establish the plan of an agricultural infrastructure project or select places for a collaborative agricultural land use project.

Health concern of dogs is the most important issue for pet owners. People who have companied the dogs long-term provide the utmost cares for their well-being and healthy life. Recently, it was revealed that the population and types of gut microbiota affect the metabolism and immunity of the host. However, there is little information on the gut microbiome of dogs. Hericium erinaceus (H. erinaceus; HE) is one of the well-known medicinal mushrooms and has multiple bioactive components including polyphenol, β-glucan, polysaccharides, ergothioneine, hericerin, erinacines, etc. Here we tested a pet food that contained H. erinaceus for improvement in the gut microbiota environment of aged dogs. A total of 18 dogs, each 11 years old, were utilized. For sixteen weeks, the dogs were fed with 0.4 g of H. erinaceus (HE-L), or 0.8 g (HE-H), or without H. erinaceus (CON) per body weight (kg) with daily diets (n = 6 per group). Taxonomic analysis was performed using metagenomics to investigate the difference in the gut microbiome. Resulting from principal coordinates analysis (PCoA) to confirm the distance difference between the groups, there was a significant difference between HE-H and CON due to weighted Unique fraction metric (Unifrac) distance (p = 0.047), but HE-L did not have a statistical difference compared to that of CON. Additionally, the result of Linear discriminate analysis of effect size (LEfSe) showed that phylum Bacteroidetes in HE-H and its order Bacteroidales increased, compared to that of CON, Additionally, phylum Firmicutes in HE-H, and its genera (Streptococcus, Tyzzerella) were reduced. Furthermore, at the family level, Campylobacteraceae and its genus Campylobacter in HE-H was decreased compared to that of CON. Summarily, our data demonstrated that the intake of H. erinaceus can regulate the gut microbial community in aged dogs, and an adequate supply of HE on pet diets would possibly improve immunity and anti-obesity on gut-microbiota in dogs.

This study investigated the physicochemical properties of Dioscorea batatas for improvement of biological activities during a three-step steaming process, steaming $120^{\circ}C$ for 30 min and hot air drying at $60^{\circ}C$ for 8 hrs. Samples were extracted with 70% ethanol and analyzed for free sugars, and organic acids were analyzed by HPLC. The DPPH & ABTS radical scavenging activities, crude saponin, water binding capacity, oil absorption, and ${\alpha}$-glucosidase activity were measured. The major free sugars in all samples were fructose, maltose, and sucrose, and the free sugar contents increased to 157~235% after the three-step steaming process compared to the control. Organic acid contents of samples treated by steaming increased to greater than 55.8 mg/100g. The ABTS radical scavenging activity significantly increased with repeated steaming process, especially after the three-step process. As the time of steaming process increased, DPPH radical scavenging activity increased from 26.99% fresh Dioscorea batatas to 80.46~97.79% after the three-step process. Crude saponin content increased rapidly as steaming time increased, but decreased after the three-step process steaming process. The water-binding capacities of the samples treated by steaming process were higher than that of the control, whereas oil absorption decreased as steaming time increased. From the results, steaming process could be suggested as beneficial for controlling fat intake. Compared to acarbose, a known antidiabetic drug, used as a positive control, ${\alpha}$-glucosidase inhibitory activity of samples treated by two-step steaming was among the samples. The results suggest that Dioscorea batatas treated by steaming process has antioxidative and anti-diabetis activities and can be used as a natural health product.

For the life quality improvement of rural elderly family placed in risk of frail, this study was investigated. Health habit, food habit, and dietary management were analyzed between elderly and middle aged family The subjects 1870 collected in 9 provinces 88 cities or guns by sampling with probability proportional to size(PPS). Questionnaire method was used. Survey was conducted by trained interviewers. Statistical analyses were performed using SAS(version 8.1). Chi-square tests and General Linear Models were used. The elderly families' characters were odd pair$(42.0\%)$, with patients$(17.6\%)$ and health examination per 1 or 2 years$(44.0\%)$. The elderly families' health habit: high of no-drink$(55.2\%)$ and low of smoke$(31.3\%)$ situation was better than those of middle aged families'. The states of diets of elderly family: having breakfast$(94.1\%)$ but 1-2 kinds$(17.7\%)$ or 3-4 kinds$(59.4\%)$ of side dishes allowed to guess lower status of food intake balance. Nutritional supplements$(27.5\%)$with tablets of vitamins$(63.5\%)$ were the most frequent states in elderly family. The aspects of dietary habit of elderly family: no instant foods$(72.6\%)$, no snack$(3.08\%)$ and no dine-out$(67.7\%)$ were significantly different with those of middle aged family. Dietary habit score(8.28/12 points) of elderly family was not significantly different with 8.22/12 points of middle aged family. Food purchase place of elderly family was mainly at traditional market$(43.6\%)$, but it was significantly different with super-market$(47.6\%)$ of middle aged family. In elderly family, traditional dish preparation was seldom$(49.8\%)$ except winter kimchi$(91.5\%)$, but significantly higher rate of in middle aged families' traditional dish preparation and winter kimchi$(94.5\%)$. From these results, more of snack, traditional dishes and dine-out were needed to improve quality of life for rural elderly.
