  • In order to improve the consumer acceptance of fragrant yellow hybrids of $Phalaenopsis$ ($Phal.$), crosses between yellow hybrid varieties were made and the obtained hybrids were investigated for horticultural characteristics as well as difference in fragrance patterns. Cross combination of $Phal.$ Brother lawrence and $Phal.$ Brother saragold yielded good seedling population of 500 plants. Segregation was noticed in color density, spot and stripe patterns on yellow color base of petal and also in fragrance. Six lines with multi-branch on flower stalk and strong fragrance flower were finally selected. Volatile fragrance components were compared among $Phal.$ Brother lawrence, $Phal.$ Brother saragold and their hybrids by GC/SAW electronic nose. In the derivative pattern of chromatogram and polar derivative pattern of fragrance, similar dominant peaks appeared on retention time 7-9 s and some hybrid lines had two strong peaks on retention time 20-25 s, respectively. Also in polar frequency pattern of fragrance obtained by $VaporPrint^{TM}$ image analysis among parent flowers and hybrids, an identical strong peak near 8 s of retention time was shown. This single fragrance component is considered a key element of fragrance in $Phal.$ Brother lawrence, $Phal.$ Brother saragold and their hybrids. This peak could be used as a marker for the breeding of fragrance in $Phalaenopsis$.

  • The electron donating ability and nitrite scavenging activity were measured in ethanol extracts from the raw, simple cooked and seasoned materials of Bibimbab (mixed rice), a Korean traditional one-dish meal. The ethanol extracts of raw fragrant edible wild aster exhibited the highest electron donating ability $(80.28\%)$, as measured by the DPPH method. When Bibimbab was compared with Kimbab and hamburgers, which are popular food, it showed the highest antioxidative activity by the DPPH method. The nitrite scavenging ability was measured in an environment similar to in human digestive organs, i.e. pH $1.2\~6.0$. Generally, the antioxidative activity decreased in the sequence pH 1.2, 3.0 and then 6.0. The simple cooked materials, with the exception of fragrant edible wild aster, increased the antioxidative potential. The seasoned materials also had a tendency to increase the antioxidative potential. In conclusion, the ethanol extract of Bibimbab showed the highest nitrite scavenging activity. Therefore, the nutritional superiority of Bibimbab was confirmed through its electron donating ability, as measured by the DPPH method, and nitrite scavenging effect.

  • The aim of this work was to determine the chemical composition of essential oil from aerial partsof Mentha arvensis L. f. piperascens (MAO) and to evaluate the effect of its fragrant chemicals on electroencephalographic (EEG) activity of human brain. The MAO was obtained by supercritical $CO_2$ extraction. The maximum yield was 2.38% at conditions of $70^{\circ}C$ and 200 bar. There were 32 volatile chemicals with 6 alcohols (67.11%), 13 hydrocarbons (17.05%), 9 esters (11.50%), 2 ketones (7.16%), 1 oxide (2.77%), and 1 aldehyde (0.56%). The major components were (Z,Z,Z)-9,12,15-octadecatrien-1-ol (50.06%), 2-hydroxy-4-methoxyacetophenone (7.50%), and 3,4-dihydro-8-hydroxy-3-methyl-1H-2-benzopyran-1-one (6.60%). Results of the EEG study showed that inhalation of MAO significantly changed the EEG power spectrum values of relative gamma, relative fast alpha, and spectral edge frequency 90%. During the inhalation of MAO, the value of relative fast alpha was significantly increased (p<0.05). On the other hand, the values of gamma and the spectral edge frequency 90% were significantly decreased (p<0.05). The present study suggests that fragrant chemicals of essential oil of M. arvensis reduce the level of mental stress and that they could be used in the treatment of psychophysiological disorders.

  • The objectives of this paper were to study the existence of resistant substance to pine gall midge from needles of Pinus densiflora, P. thunbergii, P. virginiana, and P. thunbergii${\times}$P. virginiana, and also to investigat whether terpenoids, fragrant substance contained in those species seduce or evade imago of pine gall midge to oviposit. Also, terpenoids and phenolic compounds were bioassayed on larva. The results are follows. Adults of pine gall midge oviposited indiscriminately all investigated pine species, while gall formation rate by pine gall midge showed 0% in Pinus virginiana, 9% in P. thunbergii${\times}$P. virginiana, 22% in P. thunbergii. It is suggested that young larvae is necrotized by resistant substance in the needles of P. virginiana. This results might mean that fragrant substance, terpenoids, extracted from pine species is not seducible or evadable substance. Larvae of pine gall midge placed on terpenoid and resin were not necrotized. The necrosis rate of larvae of pine gall midge cultivated in the solution of phenolic compounds extracted from needles of P. virginiana, salicylic acid and chitinase showed 89, 92, and 86% respectively. And necrosis rate was 56 and 59% in phenolic compounds extracted from P. densiflora and gallic acid respectively. So, it is postulated that phenolic compounds contained in needles of P. virginiana, salicylic acid and chitinase are resistant substance to pine gall midge.

  • This paper explores firm-specific internal and external determinants of the sustainability of "the social innovative enterprise(SIE)" by conducting a case research on Fragrant People Co. In doing so, some business and policy implications have been produced concerning the components and determinants of the sustainability of the SIE. First, entrepreneurship is a necessary factor for the survival and growth of the SIE. A social entrepreneur does manage effectively social and economic opportunities for making economic and social values interact dynamically beyond their trade-off relationship and creating new market chances. Second, the SIE also needs competitive advantages as commercial enterprises do. Valuable resources to be used for taking opportunities and avoiding threats, rare resources not to be possessed by other firms, and resources not to be easily imitated by competitors are extremely necessary for achieving objectives of the SIE. In addition, a firm must be well organized for those valuable, rare, and not easily imitated resources. Economic performance achieved by the SIE gives a birth to its financial independence, contributing to the realization of symmetric social performance. Third, the SIEs will be allowed to seek symmetrically economic and social performance only when they use sufficiently competitive advantage resources with entrepreneurship, which is composed of innovativeness, proactiveness, agility and risk-taking attitudes. In doing so, financial assistance from central or local governments may not ensure the sustainability of the SIEs. In addition, vision & value sharing(person-organization fit) can ensure the sustainability of the SIEs only when it is connected with the organizational commitment.

  • Objectives : Evaluating water and its comparisons to Yin(陰) and Yang(陽). In this section, we will look into this matter from Dongeuibogam(東醫寶鑑) and introduce an oriental perspective on the subject of water(水部). Methods : Translating Eumchanboksikjeon(飮饌服食牋) from Junsangpaljeon(遵生八牋). An in depth study of related contents and comparing to the water section(水部) of Dongeuibogam(東醫寶鑑) Results : According to the section of Varieties of Teas and Water(茶泉類) in The Discussion of Springs(論泉水), Goryum(高濂) divided water into five different types in Eumchanboksikjeon(飮饌服食牋) of Junsangpaljeon(遵生八牋). These different types are Water that runs between rocks, Clear and cold water, Sweet and fragrant water, Spiritual water and Well water. Dongeuibogam(東醫寶鑑) also analyzed 28 different types of water out the 33 its list. The idea is that one must use water differently according its origins, where it originated, when and what season to maximize the usage of the water because the energy of water would be different. Conclusions : By evaluating water, we have learned that water picks up energy and changes according to its surrounding environments. The different types of water used changes the medicinal ingredients and it affects the human body differently. One must keep in mind, the cycles of water, its energy and how it helps us live a healthier life.

  • Rice wine was prepared with medicinal plants or plant extracts to obtain a value added nutritious alcoholic tonics. Powders of ten medicinal plants (PTM) or aqueous extracts prepared from them (ATM) were added during the initial stage of fermentation. Aroma compounds of rice wine (control) and wines containing PTM or ATM were isolated by liquid-liquid continuous solvent extraction (LLCSE) and analyzed by gas chromatography-olfactometry and aroma extract dilution analysis (AEDA). Desirable aroma compounds: acetaldehyde (sweet, ethereal), benzaldehyde (sweet, fragrant), ethyl acetate (sweet) and ethyl octanoate (sweet, ethanolic) had the highest log$_3$-flavor dilution (FD) factors in ATM. Results of sensory evaluation demonstrated that intensities of undesirable aroma attributes, such as koji and yeasty notes in control, and raw medicinal herb notes in PTM, were lowest in wine with ATM. Wines made with ATM had the most attractive aroma attributes among the three different traditional Korean medicinal wines.

  • This study was performed to provide reference materials for the vegetable cultivating farmhouses by investigating profit and marketing situation for the folk vegetables. The survey areas covered 10 cities and counties including Kumsan, 72 farmhouses, and 8 crops including buffterbur and wild rocambole. As a result, the cultivated area of folk vegetables was increased as much as 13.7%, however, marketing cost was higher than that of horticultural crops, because they were not accessed to wholesale market. It was that the optimal period to sell the folk vegetables was shown like Jan. - Feb. for butterbur and day lily, Nov. - Dec. for wild rocambole, and Oct. - Nov. for kind of lettuce respectively. As the result of analyzing economical efficiency, the net profit per 0.1 ha was amounted to 3,438,000 won for butterbur, 3.291,000 won for wild rocambole 1,712,000 won for day lily, and 1,464,000 won for fatsia shoots. Besides, these four crops occupied more than 60% in cultivation area, and their profit was high. Therefore, it is necessary to foster them with special crops in Chnugnam area. The crops that require more labor time were such crops as 632.9 hours for day lily, 584.3 hours for butterbur, and 409.2 hours for fatsia shoots, whereas the crops that required less labor time were such field crops as 219.2 hours for fragrant edible wild aster and 233.8 hours for kind of lettuce.

  • This study investigated the stimulative or sedative effects of inhaling fragrant essential oils (EOs) by using a forced swimming test (FST) with mice. This behavioral test is commonly used to measure the effects of antidepressant drugs. The inhalation by mice of EOs, such as ginger oil (p<0.05), thyme oil (p<0.05), peppermint oil (p<0.05), and cypress oil (p<0.01) resulted in 5% to 22% reduction of immobility. The same results were achieved when over-agitation was artificially induced in the mice by an intraperitoneal injection of caffeine (a psycho-stimulant). In contrast, inhalation of some EOs by the mice resulted in increased immobility. To evaluate more correctly the sedative effects of EOs, the immobility of over-agitated mice induced with caffeine was ascertained after the inhalation of various EOs. Inhalation of lavender oil (p<0.01) and hyssop oil (p<0.01) increased the immobile state in mice that were treated with caffeine. The results of this study indicate that the inhalation of essential oils may induce stimulative or sedative effects in mice.
