  • The amino acid contents, physical and sensory properties for the loins of crossbred pigs (JJ90: live weight of 90∼100 kg; and JJ110: live weight of 110∼120 kg) and crossbred Jeju black pig (JB90: live weight of 90∼100 kg) were evaluated to investigate their quality. The total contents of structural amino acid, which were 18.15∼20.22% for all the samples without showing significant differences, included significant amount of glutamic acid, aspartic acid, lysine and leucine. The free amino acid content was 0.486% for JB90, which was greater than JJ90 and JJ110. Also, significant amount of taurine, serine, glycine, alanine, valine, and leucine could be observed in the free amino acid content of the samples. The redness (a/sup */) and yellowness (b/sup */) of JB90 were significantly higher titan those of JJ90 and JJ110. The water holding capacity, hardness, chewiness, juiciness and palatability of JJ110 and JB90 were higher than those of JJ90, but their difference was not significant.

  • This study investigated the antioxidative activity and whitening efficacy of Crataegus pinnatifida Bunge fruit 70% ethanol extract (CFE). The total polyphenol contents of CFE was 61.31 mg/g, and the total flavonoid contents was 25.42 mg/g. The electron donating ability of CFE at a concentration of $1,000{\mu}g/mL$ was 85.80%. The ABTS radical scavenging activity, and reducing power of CFE at a concentration of $1,000{\mu}g/mL$ were 17.3% and 0.31, relatively. The maximum permissible levels of CFE in melanoma cells were $100{\mu}g/mL$. CFE at $50{\mu}g/mL$ reduced melanin contents by 8.5%. CFE at $1,000{\mu}g/mL$ reduced intracellular tyrosinase activity by 46.83%. Collectively, the results of this study suggest that CFE effectively inhibited tyrosinase activity, whereas melanin synthesis was weak. These results suggest that Crataegus pinnatifida Bunge fruit could be used as a whitening agent and antioxidant resources for functional foodstuffs, cosmetics, and beauty industrial materials.

  • Hoseonmu belongs to the genre of a composite of song, music, and dance. At that time, there was no widely known record of Hoseonmu in Baekje, but it is clear that it was popular enough to be invited to Changan by Emperor Yang of Sui. The musical instruments, songs, and dances were analyzed through the research method of literature and the content of the Hoseonmu version was established. The setting of the stage for the performance of Baekje instrumental music reveals its characteristics through sabangak from Gigaku in the neighboring countries. The stage for Hoseonmu was set up utilizing the creation of the imperial performance stage in the Baekje instrumental music. In particular, Hoseonmu has two types: heavenly and earthly. The heavenly Hoseonmu can be found on the wall of the Cave No. 220 formed in the Chodang (618-707) era. They include Dongbang Pharmacopoeia jingbian and Western Paradise jingbian. Hoseonmu would have chosen to be the fast-paced spinning dance. Motions for Hoseonmu could be set up through them. Meanwhile, Mimaji's instrumental dance is presented. Six dancers appear in two turns of the performance. Four dancers in front row and other two in the back are dressed up as hunters, wearing goblin masks, and holding flowering plum tree branches in their right hands. Through this, the movements and costumes of Hoseonmu are reproduced in more detail. Various sectors of education, theater, dance, and tourism in the Hoseonmu contents of Baekje instrumental music contributed to the Korean Wave.

  • REEs of ginsengs(2, 3, 4 years) from the granite, phyllite and shale areas, Keumsan, are analysed and compared with the their soils. In the weathered soils, high element contents are shown in the LREE of the granite and in the HREE of the phyllite. The granite dominantly show positive correlation relationships. In the field soils, the phyllite are high while the granite are low. Relationships of the contents and correlation relationships can be explained with mineral assemblages and contents within soils, and their solubilities. In the host rocks, high contents are found in the LREE of the granite and HREE of the phyllite. The rocks dominantly show positive relationships. In the ginseng, high contents are shown in the 2 year for the shale and granite, and the 4 year for the phyllite. Element pairs mainly show positive relationships. Comparing of the same ages, the granite are mainly high. In the ratios between the soils and the ginsengs, differences of the several hundred to ten times are found, but dominantly, of the several hundred times in the shale and phyllite, and of the several ten times in the granite. The differences are big in the 3 year, and small in all REE of the 2 year from the shale and granite. while, in the phyllite, big in the LREE of the 2 year and HREE of the 3 year. Based on the absorption of the leachate by the ginsengs within soils, contents and correlation relationships of the ginsengs from the different soils can be explained with mineral assemblages, solubilities of the constitutional minerals and phyio-chemical affects influenced on the solubility. Of the three different soils, the ginsengs of the granites are chemically more similar to their soils.

  • This study was carried out to investigate the total polyphenol and flavonoid contents and antioxidative activities of the methanol extracts of Citrus sunki, C. unshiu and C. natsudaidai peels before and after drying. Total polyphenolic content was high in the citrus peels before drying compared to the dried peels, and highest in the order of C. sunki, C. natsudaidai and C. unchiu. On the other hand, flavonoid content was high in the dried citrus peels than in the citrus peels before drying, and was highest in the order of C. unshiu, C. natsudaidai, C. sunki, but in dried peels it was highest in the order of C. natsudaidai, C. unshiu, C. sunki. DPPH radical scavenging activity was highest in the order of C. natsudaidai, C. unchiu, C. sunki, and that in the citrus peels before drying was higher than in the dried peels. Inparticular, C. natsudaidai peels before drying showed higher activity than vitamin C in 0.5 or 1.0 mg/100 g. Hydrogen peroxide scavenging activity was highest in the order of C. unshiu, C. natsudaidai, and C. sunki in the citrus peels before drying. The dried peels were highest in the order of C. unshiu, C. natsudaidai, C. sunki at 0.5 mg/100 g, but high in order of C. natsudaidai, C. unshiu and C. sunki at more than 1.0 mg/100 g. Inparticular, all C. natsudaidai peels displayed high activity more than 87% at 2.0 mg/100 g. Clear patterns in alkyl radical scavenging activity could not be confirmed in Citrus species whether before or after drying of peels. Hydroxyl radical scavenging activity was highest in the order of C. natsudaidai, C. unshiu and C. sunki but was relatively low compared to the scavenging activity of other activated oxygen species.

  • This study aimed to produce fermented extracts with sugar made from lotus root (LR) and Platycodon grandiflorum (PG), using lactic acid fermentation, and confirmed their physiological and anti-oxidative activities as basic data for manufacturing functional drinks through sensory tests. For the final sugar concentrations, PG showed $48.1^{\circ}brix$ and LR showed $52.0^{\circ}brix$. Sugar concentrations during lactic acid fermentation following dilution of sugar to $12^{\circ}brix$, ranged from $11.5{\sim}12.1^{\circ}brix$ for PG and $11.9{\sim}12.4^{\circ}C$ for LR. During lactic acid fermentation, lactic acid bacteria numbers tended to decrease in both fermented LR and PG extracts with sugar as the fermentation period increased. For DPPH radical scavenging ability, LR was three times higher in control without lactic acid fermentation while PG showed significant increases in L. acidophilus (77%), L. brevis (90%), and L. delbrueckii (177%) during lactic acid fermentation. For total polyphenol content, LR showed a higher concentration than PG, and except for fermented L. delbrueckii extract showing similarity with the control, contents of fermented extracts decreased. In the case of PG, CUPRAC, increased significantly in L. brevis, whereas FRAP, increased significantly in L. delbrueckii with lactic acid fermentation. For reducing power, except for fermentation with L. brevis, all PG showed lower reducing power activities. In the sensory test of fermented LR and PG extracts with sugar, both fermented extracts showed better results with L. brevis or L. delbrueckii than control or those with L. acidophilus in every item. Based on these results, it is highly possible to develop fermented extract drinks with sugar using LR or PG. In particular, lactic acid bacteria such as L. delbrueckii and L. brevis showed generally higher activities with potential as a functional drink.

  • The present study was conducted to evaluate the effects of Agarum cribrosum on weight change and defecation states in rats with constipation induced by loperamide. Food intake and body weight both decreased in the 5% Agarum cribrosum and loperamide-treated group (SD5) and 10% Agarum cribrosum and loperamide-treated group (SD10), whereas fecal water contents increased by 1.6 and 2.1-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of Agarum cribrosum. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also lower than those in the control group. The results of the present study demonstrated that Agarum cribrosum might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.

  • This study applied the theory of Landscape Ecology to representative resources of Jeju Olle-gil, which is a representative subject of walking tourism, to identify ecological characteristics and to establish a technique for landscape ecological analysis of Olle-gil resources. Jeju Olle Trail type based on the biotope type, major land use, vegetation status around Olle Trail and roads were divided into 12 types. Based on the type of ecological tourism resource classification, the Jeju Olle-gil walking tourism resource classification was divided into seven types of natural resources and seven types of humanities resources, and each resource was characterized by Geotope, Biotope, and Anthropopope, just like the landscape ecology system. Geotope resources are strong in landscape characteristics such as coast and beach, rocks, bedrocks, waterfalls, geology and Jusangjeolli Cliff, Oreum and craters, water resources, and landscape viewpoints. The Biotope resources showed strong ecological characteristics due to large tree and protected tree, Gotjawal, forest road and vegetation communities, biological habitat, vegetation landscape view point. Antropotope include Culture of Jeju Haenyeo and traditional culture, potting and lighthouses, experience facilities, temples and churches, military and beacon facilities, other historical and cultural facilities, and cultural landscape views. Jeju Olle Trail The representative resources for each type of Jeju Olle Trail are coastal, Oreum, Gotjawal, field and Stonewall Fencing farming land, Jeju Village and Stone wall of Jeju. In order to learn about the components and various functions of the resources representing the Olle Trail's ecological culture, the landscape ecological technique was interpreted. Looking at the ecological and cultural characteristics of coastal, the coast includes black basalt rocks, coastal vegetation, coastal grasslands, coastal rock vegetation, winter migratory birds and Jeju haenyeo. Oreum is a unique volcanic topography, which includes circular and oval mountain bodies, oreum vegetation, crater wetlands, the origin and legend of the name of Oreum, the legend of the name of Oreum, the culture of grazing horses, the use of military purposes, the object of folk belief, and the view from the summit. Gotjawal features rocky bumps, unique microclimate formation, Gotjawal vegetation, geographical names, the culture of charcoal being baked in the past, and bizarre shapes of trees and vines. Field walls include the structure and shape of field walls, field cultivation crops, field wall habitats, Jeju agricultural culture, and field walls. The village includes a stone wall and roof structure built from basalt, a pavilion at the entrance of the village, a yard and garden inside the house, a view of the lives of local people, and an alleyway view. These resources have slowly changed with the long lives of humans, and are now unique to Jeju Island. By providing contents specialized for each type of Olle Trail, tourists who walk on Olle will be able to experience the Olle Trail in depth as they learn the story of the resources, and will be able to increase the sustainable use and satisfaction of Jeju Olle Trail users.

  • The purpose of this study is to determine the possibility of using Sophorae fructus as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Sophora fructus were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 75.9%, 16.4%, 2.41%, and 5.2%, respectively, while the calories of Sophora fructus was 337.3 kcal. Total dietary fiber was 15.07% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 1.09% and 10.36%, respectively. The protein was composed of a total of 18 different kinds of amino acids. The contents of essential and non-essential amino acids were 2,310.91 mg and 5,218.52 mg. The K was the largest mineral followed by Ca, P and Mg, which means Sophorae fructus is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 24.94%, 32.40%, and 32.86%, respectively. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of vitamin C in Sophorae fructus was higher than that of any other plant, which suggests that it could increase blood elasticity. The content of rutin, which is responsible for capillary vessel permeability, was 1.78%. The contents of water soluble antioxidative materials in 1 mL of water-extracted Sophorae fructus were $4.95\;{\mu}g$ which is comparable to 1,560.96 mmol of vitamin C in antioxidant effect. The general nutrients and other antioxidatant bioactive materials in Sophorae fructus were also potential materials for good health food. It is expected that a follow up study on Sophorae fructus through developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.
