  • This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance. The survey results show that promotion of local foods through education, and as well as incorporation of new ingredients are both highly effective ways to commercialize local foods for tourism. The results also indicate that taste, nutrition, and appearance of food should be considered in order to improve quality.

  • Shade affects turf quality by reducing light for photosynthesis. The shade tolerance of the tropical grasses, Digitaria longiflora and Axonopus compressus were evaluated against Stenotaphrum secundatum (St. Augustinegrass). The grasses were established under shade structures that provide 0%, 50%, 75% or 90% shade level for 30 days. A suite of leaf traits, recorded from similar leaf developmental stage, displayed distinct responses to shade conditions. Leaf length, relative to control, increased in all three species as shade level increased. The mean leaf extension rate was lowest in St. Augustinegrass (80.42%) followed by A. compressus (84.62%) and D. longiflora (90.78%). The higher leaf extension rate in D. longiflora implied its poor shade tolerance. Specific leaf area (SLA) increased in all species with highest mean SLA increase in D. longiflora ($348.55cm^2mg^{-1}$)followed by A. compressus ($286.88cm^2mg^{-1}$) and St. Augustinegrass ($276.28cm^2mg^{-1}$). The highest SLA increase in D. longiflora suggested its lowest performance under shade. The percent green cover, as estimated by digital image analysis, was lowest in D. longiflora (53%) under 90% shade level compared to both species. The relative shade tolerance of the three turfgrasses could be ranked as St. Augustinegrass > A. compressus > D. longiflora.

  • Potato Virus Y(PVY), vein necrosis strain, in Korea causes severe symptoms on burley tobacco(Nicotiana tabacum L.). As the results, programs to incorporate PVY resistance into commercial cultivars were initiatEd. But the development of the homozygous fertile line resistant to PVY is time consumming. This study was conducted whether the Fl hybrid could be used to reduce the yield losses caused by PVY. Four F1 hybrids were made between male - sterile(ms) NC 107 and KB 107 as maternal parent, and TC 612 and TC 613 as Pollen donor, respectively, and were evaluated for their PVY resistance and negatively associated traits. (ms NC 107 X TC 612) F1, named as KB 109, Ivas applied to yield trial and compared with commercial cultivars for the level of disease resistance, agronomic characteristics, chemical contents and physical properties. All Fl hybrid could be used commercially as the PVY resistant cultivar. Especially KB 109 have the resistance against PVY, tobacco mosaic virus and black shank(Phytophthora parasitica var. nicotianae). It had wider leaves, flowered one day later, and yield of acceptable quality was higher than that of Burley 21, standard cultivar in Korea.

  • This study examined the effects of cage rearing system and backyard raising system on fatty acid profile of egg in laying hens during 9 weeks. Two hundred hens, 70-wk-old, Hy-line Brown, were used in this study and fed basal diets. 100 hens, randomly collected from facility, were transferred to cage rearing system and 100 remaining hens were moved to backyard raising system. For overall period, higher unsaturated fatty acid percentages in two different rearing systems than did saturated fatty acid (SFA) were observed. In unsaturated fatty acid compositions, both rearing system showed a higher mono unsaturated fatty acid (MUFA) contents than poly unsaturated fatty acid (PUFA) contents. Egg quality traits of laying hens reared in backyard system had considerably lower contents of SFA and higher contents of MUFA compared with eggs from cage rearing system (P<0.05). In addition, eggs from cage rearing system resulted in a significantly lower n-3 contents and higher n-6:n-3 ratios and CLA contents in comparison with backyard raising system (P<0.05). However, no significant effects of two different rearing systems on PUFA, PUFA:SFA ratio, and n-6 contents were observed during the experimental period. In conclusion, this result suggests that cage rearing system and backyard raising system will play an important role in improving egg production as functional foods.

  • The textile designs expressed in contempor-ary fashion are studied in this paper. The dec-orative paintings have been encouraged to be-ing adapted in textile designs for apparel as a motif of the surface design to promote the ar-tistic atmosphere in it. Adopting paintings in textile design through the method of printing is valid to improve the fashion in several reasons as follow : First the printed paintings on the fabrics could be possible to contribute individuality and creativity to the fashion im-proving the quality of textile design and the taste of the consumer as well, Second the limitted types of the clothing construction for preparing the proper space to reveal a paintings is needed on the costume The simple clothing types of loose from the body or fitted to the body are easy to adopt and to recreat the paintings on the apparel. Third the paintings which have been favored in use for the textile design are mostly derived from the abstract arts rather than re-alistic paintings for its decorative traits. Fourth a proposal to adapt the other genre of the art could be encouraged to enrich the field of textile and fashion design. Fifth aquisition of the individuality and the creativity in fashion design to differenciate in international market could be obtained through the adaption of Korean paintings which is ap-preciated with Korean sentiment and mind. This would be one of the essential and advis-able ways for designers to solve the problems which have been consistently pusuing in the area of Korean industrial design to find the Korean design model.

  • Objectives: Medical schools are trying to improve the quality of medical education by offering students better medical curriculum. In this study, we intend to provide basic information for improvement and development of medical curriculum by analyzing the medical curriculum of domestic and foreign medical schools. Methods: Based on various materials, we selected out 5 domestic medical schools and 11 foreign medical schools and collected materials relevant to medical curriculum of each medical school. Then, we divided collected materials into four domains(educational objectives, educational contents, educational assessment, and curriculum implementation), and analyzed them synthetically. Results and Conclusion: First, concerning the educational objectives, it is necessary that more various educational objectives are included to medical curriculum. Especially, there is a growing need for medical curriculum reflecting social responsibility and requests of local community. Second, educational contents should be constantly improved and constructed considering students' academic achievement levels and traits. Third, not only students but also educational program, educational contents, and professors should be included to the objects of educational assessment. Also, various assessment methods should be developed. Finally, especially for domestic medical schools, it is necessary to make use of more educational specialists in medical education.

  • Sleep problems occur frequently among patients with Prader-Willi syndrome (PWS). The most common problem is excessive daytime sleepiness (EDS) that are closely related to of sleep-related breathing disorder (SRBD) such as obstructive sleep apnea (OSA) and congenital hypoventilation syndrome. Obesity, craniofacial dysmorphism and muscular hypotonia of patients with PWS may increase the risk of SRBD. Sleep apneas can interrupt the continuity of sleep, and these disruptions result in a decrease in both the quality and quantity of sleep. In addition to SRBD, other sleep disorders have been reported, such as hypersomnia, a primary abnormality of the rapid eye movement (REM) sleep and narcolepsy traits at sleep onset REM sleep. Patients with PWS have intrinsic abnormalities of sleep-wake cycles due to hypothalamic dysfunction. The treatment of EDS and other sleep disorders in PWS are similar to standard treatments. Correction of sleep hygiene such as sufficient amount of sleep, maintenance of regular sleep-wake rhythm, and planned naps are important. After comprehensive evaluation of sleep disturbances, CPAP or surgery should be recommended for treatment of SRBD. Remaining EDS or narcolepsy-like syndrome are controlled by stimulant medication. Bright light therapy might be beneficial for disturbed circadian sleep-wake rhythm caused by hypothalamic dysfunction.

  • The objective of this study was to investigate the effect of the fat reduction on the physicochemical and microbiological characteristics of fermented sausages during ripening and drying. Low fat fermented sausages were produced with different fat levels (30%, 20%, 10%, and 5%) under ripening conditions and fermented process. Samples from each treatment were taken for physicochemical and microbiological analyses on the 0, 1, 2, 3, 4, 5, 7, 10, 14, and 21st day of ripening. In proximate analysis, the fat reduction in sausages produced an increase in moisture, protein and ash contents during ripening and drying (p<0.05). The weight losses were significantly higher in high fat formulations during the first 4 days, whereas those were higher in low fat ones after 10 days of storage (p<0.05). Fat reduction was responsible for an increase in shear force values after 3 days of storage. The volatile basic nitrogen (VBN) value of the low fat samples was significantly higher (p<0.05). Low fat sausages reduced the extent of lipid oxidation. The lower fat level produced redder sausages. Total plate bacteria and Pseudomonas counts of sausages showed no significant differences. Production of low fat sausages resulted in the physicochemical and microbiological attributes equal to or better than the high fat sausages without negative effects, except only a higher VBN and weight loss.

  • Recent advances in genome sequencing technologies have enabled humans to generate and investigate the genomes of wild species. This includes the big cat family, such as tigers, lions, and leopards. Adding the first high quality leopard genome, we have performed an in-depth comparative analysis to identify the genomic signatures in the evolution of felid to become the top predators on land. Our study focused on how the carnivore genomes, as compared to the omnivore or herbivore genomes, shared evolutionary adaptations in genes associated with nutrient metabolism, muscle strength, agility, and other traits responsible for hunting and meat digestion. We found genetic evidence that genomes represent what animals eat through modifying genes. Highly conserved genetically relevant regions were discovered in genomes at the family level. Also, the Felidae family genomes exhibited low levels of genetic diversity associated with decreased population sizes, presumably because of their strict diet, suggesting their vulnerability and critical conservation status. Our findings can be used for human health enhancement, since we share the same genes as cats with some variation. This is an example how wildlife genomes can be a critical resource for human evolution, providing key genetic marker information for disease treatment.
