The objectives of this study were to find the nuruk fungal isolate for Korean traditional rice wine and to compare the tastes of rice wines made with its single inoculum. The fungal isolates including the species of Absidia, Mucor, Rhizopus and Aspergillus were used for Korean traditional rice-wine production. The four species were cultured and measured for productions of amylase under various water contents. The four different species tested were different in their growth under the rice cereals with different moisture contents; the species of Absidia and Rhizopus grew better compared to the other species under the lower moisture conditions. The tastes and alcohol concentrations of the rice-wines made with each different inoculum were compared with those of commercial rice wines made with traditional method. As a result, it was speculated that the traditional rice wines were made with nuruk, which is mainly composed of Zygomycetous fungi, such as Absidia, Mucor, and Rhzopus. Also, it was strongly suggested that the traditional nuruk might not be a source of amylase, but a source of fungal inoculum.

As public gives more attention on the well being trend, the aim of this study on the Sommelier - an industry profession in the hotel and food service industry is to suggest the educational plan to meet the demand as a professional and to help establish the direction to the effective curriculum. Findings from this study showed that a Sommelier need to possess knowledge in not just wine but in areas such as foreign language, computer, management, hotel and restaurant, global manner, and etc. It was also recommended to authorize the sommelier license as an official and to develop educational entities for sommelier.

The yellow fungal isolates inhabiting at the cereals (Hwang-Kuk, HK-fungi) were widely collected from the mejus and nuluks in Korea; the meju is a raw material for Korean traditional foods for soysauce and soypaste, and the nuluk is a raw material for Korean traditional rice wine. These isolates, well known as an Aspergillus oryzae producing amylase for Korean rice wine or producing protease for soybeans, were compared with Aspergillus species known. All isolates were microscopically observed to be a species of A. oryzae or its related, but to be difficult to be identified. Thus, RAPD-DNA techniques were applied for these isolates and analyzed with nummerical values using NT-system, or Ecological programs or Factorial analyses. Several common bands of RAPD-DNA in the 28 isolates were synthesized with the different OPD primers and speculated to be used for identification of HK fungi. The HK-fungi isolated were revealed to belong to the group of A. flavus previously defined. Particularly, the isolates collected from mejus were analyzed to be more closed to A. flavus, The species of A. flavus, A. oryzae and A. sojae were grouped at the values lower than those indicating the diversity of species. In other words, these three fungal species were not distinguishable and all isolates known as a HK-fungus were very closed to A. flavus, All isolates were not diversified at groupings of RAPD-DNA, and considered to be not the natural flora at the mejus or nuluks. The meju or nuluk having the above fungi as the fungal flora were speculated to be not termed "Korean traditional foodstuffs".The yellow fungal isolates inhabiting at the cereals (Hwang-Kuk, HK-fungi) were widely collected from the mejus and nuluks in Korea; the meju is a raw material for Korean traditional foods for soysauce and soypaste, and the nuluk is a raw material for Korean traditional rice wine.

Inquiring activities on the acoustic phenomena have been carried out by using a sound card installed in a personal computer. A sound card is cheaper and more accessible to the students than the precision equipment such as a function generator or an oscilloscope. The students record the sounds from various acoustic phenomena to the sound card. Then they analyze the frequency spectrums of that sounds by using a program. Inquired phenomena include beat by two tuning forks, sound from Rijke tube, pouring sound, breaking of a wine glass and pop-up sound of a wine bottle. Through these activities students perform quantitative analysis of various phenomena due to superposition, resonance and standing wave.

최근 국내시장에 판매되고 있는 막걸리의 종류는 매우 다양하며, 주류시장에서도 큰 수입원으로 부각되고 있다. 또한 국내뿐 만아니라 해외수출 비중도 높아지고 있으며, 주류관련 기업에서는 고급화 전략으로 마케팅을 하고 있다. 막걸리와 더불어 상품화 비중이 높아지고 있는 기능성 주류는 미용, 건강, 갈증해소 등 다양한 효능을 가지고 있으나, 일반적인 주류의 홍보에 비해 상대적으로 미비한 상태이다. 본 연구의 일부분으로 제작되는 막걸리는 피부미용, 면역력 강화, 뇌기능 개선 등의 효과를 갖는 감태를 주성분으로 하여 제조한 기능성 주류이다. 따라서, 본 연구에서는 감태를 이용한 기능성 막걸리의 제조과정과 막걸리의 특성을 파악한 효과적인 홍보 방안을 위한 콘텐츠 설계 및 개발에 대한 제안한다.

Folk Remedies symbolize the medical art of the common people, and contain their special emotion and colloquial expressions. They are medical treatments in which the medical history and the tradition and the soul of a people are incorporated. They are handed down in various ways. This study introduces some of folk remedies. For example, powder of tigers' bones heals neuralgia. Rice wine brewing up with ginger is effective in a cold. Water boiling with safflower does good in neuralgia. Pasting herba houttuyniae takes effect in skin disease. To Decoct and drink old hardy orange is effective in urticaria. Water boiling with fructus corni alleviates a fever. Camellia oil or rhizoma cnidii or iris is used for the extermination of vermin and the antiseptic. In the end, the practical application of these remedies to the resources of industry and education will be discussed.

We have recently discovered that mycelium of Phellinus linteus, popular medical mushrooms in Korea, possess alcohol dehydrogenase and produce alcohol. In the present study, it was examined that the effect of fermented rice wine made by using mycelium of P. linteus (FLMP) on the expression of in-flammation-related proteins in both $HepG_2$ cells and rats. To examine the effect of FLMP on the morphology and expression of inflammatory proteins in $HepG_2$ cells, the cells were incubated with ethanol, and FLMP for 24 hours, and then analyzed by microscopic observation and Western blot and reverse transcription polymerase chain reaction (RT-PCR). While ethanol induced the morphological change accompanied with cell debris formation and scattering on $HepG_2$ cells, FLMP had no effect. The results of Western blot and RT-PCR analyses showed that the level of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-1 and COX-2 was induced by ethanol, however, FLMP inhibited the expression of these proteins and its mRNAs. In the animal model, the value of flutamate oxaloacetate transaminase and glutamate pyruvate transaminase was significantly increased by administration with ethanol. But the group administrated with FLMP showed lower levels on the changes of these markers compared with ethanol-administrated group. Besides, the results of Western blot and RT-PCR analyses showed that the expression of inflammatory proteins such as iNOS, COX-1 and COX-2 was not affected by FLMP administration in rat liver. About histopathological and immunohistochemical observations, inflammatory loci were markedly decreased in the FLMP-administrated rat compared to ethanol-administrated rats and showed weaker COX-2 and iNOS jmmunoreactions. These results suggested that FLMP showed slight changes on the inflammatory proteins expression compared to ethanol and FLMP may be used as a functional alcoholic beverage.

The fungal isolates of Mucorales, directly collected from Korean traditional raw materials of Nuruk (raw material for Korean rice wine) and Meju (raw material for Korean soysauces), were compared with those of Rhizopus oryzae purchased. The fungal isolates of Rhizopus, Mucor, and Absidia mostly identified as based on the morphological observations, were evaluated with the PCR-polymorphic bands. The PCR-polymorphic bands of the genomic DNA reacted with the primers of OPD series tenmer were various, but showed averaged 4 to 6 in the agarose-electrophoresis. The dissimilarity coefficient (DC) between two isolates were compared by the cluster analyses, dendrogams and polar ordinations. The isolates of R. oryzae known. showed several groupings within the lower value of DC and were divided to two groups of amylo-process and other fungi with other purposes. The isolates unidentified were identified by the DC made of this results. Taxonomy of these isolates made by the morphological observations were consistent with those resulted above in most case but not in all aspects. More works were needed with the isolates known for detail informations of Mucorales.
