  • This study was carried out to determine the basic mycelial culture conditions for Poria cocos growth. According to colony diameter and mycelial density, suitable media for mycelial growth were Malt yeast extract, Potato dextrose agar, Yeast extract agar, and Yeast malt agar. The optimum temperature for mycelial growth was between 25 and $35^{\circ}C$, and the optimum pH value was between 4 and 7. Carbon and nitrogen sources were fructose and yeast extract. The optimum C/N ratio was about 10 to 1 with 2% glucose. Other minor components for optimal growth were thiamine-HCl and nicotinamide as vitamins, acetic and lactic acid as organic acids, and $MgSO_4{\cdot}7H_2O$ and $FeSO_4{\cdot}7H_2O$ as mineral salts.

  • The isolation and chemical characterization of yellow food pigments from Monascus purpureus were studied according to the compositions of media. Monacus yellow pigments were isolated and purified by solvent fractionation, silicagel column chromatography, TLC and HPLC. The retention time of Monascus yellow pigments isolated by HPLC was respectively 5 min(I) and 9 min(II) as the yeast malt extract agar(YMA) media and was respectively 4.6 min(III), 5 min(I) 5.7 min(IV), 8.3 min(V), 9 min(II) and 10.7 min(Ⅵ) at the malt extract agar(MEA) media. The structure of monascin(I), ankaflavin(II), 6,11-dihydrorubropunctatin(III), 6,11-dihydromonascorubrin(V) and unknown compounds(IV,Ⅵ) was elucidated by EI-Mass, H and C NMR, UV-visible spectrometer. Therefore, it was suggested that 6,11-dihydrorubropunctatin(III) and 6,11-dihydromonascorubrin(V) are new intermediates of Monascus yellow pigments.

  • Korean traditional Sikhye is made from rice and malt. Since 1740, there have been many records about the method of making traditional Sikhye, generally used in the folks. And the first records of sugar addition Sikhye were found In 1924. Therefore commercial sugar Sikhye is not traditional. Traditional Sikhye uses 30% of rice and malt (dry weight) as raw material, and main content is maltose. However commercial Sikhye uses only 3% of cooked rice, and adds 10% of sugar, .Even though some domestic Sikhye used sugar, the amount of added sugar does not exceed 115 of raw materials. Therefore, commercial Sikhye differs from not only traditional Sikhye but also domestic sugar Sikhye.

  • 꽃송이버섯(Sparassis crispa DSMZ 5201)의 균사를 사용하여 균사외 효소활성을 측정하였다. Yeast-malt extract-glucose 배지를 사용하여 $24^{\circ}C$에서 15일간 배양 후 배양여액을 조효소원으로 사용하였을 때, $\alpha$-amylase효소의 활성은 44.27 unit/$mg{\cdot}protein$이었다. 배양여액 중의 Protease, CMCase, $\beta$-glucosidase, chitinase 및 exo-$\beta$-1,4-glucanase의 세포외 효소활성은 상대적으로 높았으나, xylanase 효소활성은 낮게 나타났다.

  • One of the main processes of tenderizing beef in Joseon Dynasty was chemical methods involving Apricot seeds, manchu cherry twig and leaves, bamboo skins, mulberry tree bark, mangsa (硭砂), salmiacum (磠砂), alcohol, fermented malt, and original honey. This study analyzed and compared the effect of broussonetia papyrifera, fermented malt, cherry trees, and mulberry tree bark from old cookbooks. Tenderizing beef with cherry trees was most effective in the experiment on shearing force, TPA, and electrophoresis of beef. According to sensory evaluation and electrophoresis test results, tenderized beef with mulberry tree bark was slightly more preferred over the method using cherry trees. However, in accordance with the above mentioned experiment, quantitative descriptive analysis showed that the most common tenderizing material was derived from morus alba powder.

  • Helicobacter pylori is one of the most commonly encountered human pathogens. It has been shown to be closely associated with peptic ulcer disease (PUD), gastric adenocarcinoma, and the gastric mucosa-associated lymphoid tissue (MALT) that may lead to gastric lymphoma. The current diagnostic methods include histology, microbiological culture, classic serology unease activity detection, polymerase chain reaction (PCR) and stool antigen detection. Its treatment modality options are multiple; however, a triple regimen consisting of a proton pump inhibitor (PPI), and two antibiotics for 10 to 14 days is preferred. Drug resistance is a growing problem in this organism and new therapeutic options are currently limited .

  • It is important to encourage the restoration of the production of traditional Korean liquors, which is being undertaken by individuals, companies, and the government. The flavours of traditional liquors differ and depend on the environment and raw materials. This study on the traditional Gangwondo liquor is based on literature review and oral tradition. The history of and the scientific rationale behind the use of malt, which is a characteristic feature of the traditional Gangwondo liquor manufacturing process, must be systematically researched. It is important that independent two-step fermentation is used in Gangwondo, while in other regions simultaneous two-step fermentation is used. We expect that the current research on fermentation will be useful for the production of various traditional liquors. The total production of traditional liquors will need to be increased to meet the needs of the world festival, 2018 Olympic Winter Games in Pyeongchang.

  • The prevalence of cheek lymphoma, especially a mucosa-associated lymphoid tissue lymphoma (MALT), is very rare. Non-specific symptoms and image findings of cheek lymphoma may mimic benign entities and make it difficult to diagnose. In this case report, we present a case of MALT lymphoma of the cheek mimicking benign entities on computed tomography and magnetic resonance imaging.

  • Dependency parsing is a decision problem of the syntactic relation between words in a sentence. Recently, deep learning models are used for dependency parsing based on the word representations in a continuous vector space. However, it causes a mislabeled tagging problem for the proper nouns that rarely appear in the training corpus because it is difficult to express out-of-vocabulary (OOV) words in a continuous vector space. To solve the OOV problem in dependency parsing, we explored the proper noun embedding method according to the embedding unit. Before representing words in a continuous vector space, we replace the proper nouns with a special token and train them for the contextual features by using the multi-layer bidirectional LSTM. Two models of the syllable-based and morpheme-based unit are proposed for proper noun embedding and the performance of the dependency parsing is more improved in the ensemble model than each syllable and morpheme embedding model. The experimental results showed that our ensemble model improved 1.69%p in UAS and 2.17%p in LAS than the same arc-eager approach-based Malt parser.
