Fourteen samples of kimchies and soy bean pastes were used to isolate strictly anaerobic bacteria on complex BL agar and on a selective BS agar for bifidus bacteria. About $10^7$ ~ $10^8$ colonies per g sample were developed on BL agar under strictly anaerobic conditions, while BS agar supported the growth of $10^3$ ~ $10^6$ colonies per gram sample at the same condition. All colonies developed on BS agar at anaerobic conditions grew in aerobic conditions and did not show fructose6-phosphate phosphoketolase activity. Type cultures of Bifidobacterium did not grow in PYG medium containig more than 3% NaCI. From these results it is conduded that salted fermented food cannot support the growth of strictly anaerobes induding Bifidobactenum.

Objectives : Imyosan (IMS), a drug preparation comprised of Phellodendri Cortex (PC) and Atractylodis Rhizoma (AR), is commonly used as a traditional herbal medicine in Korea and China for the treatment of various inflammatory diseases. However, little is known about the effect of IMS and its component herbs on inflammatory mediators in RAW 264.7 cells. Therefore, in this study, methanol extracts of IMS and its component herbs were examined to determine if they inhibited inflammatory effects in RAW 264.7 cells. Methods : Cytotoxic activity of IJHT and its components on RAW 264.7 cells was using 5-(3-carboxymethoxyphenyl)-2H-tetrazolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression were detected by western blot. Results : Methanol extract of IMS and its component herbs were significantly reduced iNOS and COX-2 expression as well as NO, PGE2, $IL-1{\beta}$ and IL-6 production in RAW 264.7 cells. Conclusions : The results of this study indicated that the anti-inflammatory effect of Imyosan extract is more potent than that of extracts of its component herbs in macrophages.

Growing industrialization and climate change lead to the huge demand for clean drinking water. Desalination of sea water by membrane separation process is one of the alternative and economically viable methods to fulfil the demand for water. In the membrane separation process, the presence of 2D materials enhances the performance of membrane by facilitating the water permeation, salt rejection, flux rate, and selectivity compared to the traditional reverse osmosis thin-film-composite membranes. In this review, composite membranes with different kinds of 2D materials are discussed on the basis of materials synthesis, characterization and desalination process.

The origines of the Western roasting culture and East Asian boiling culture were studied and the importance of primitive pottery culture (8000-5000 BCE) in the Korea Strait coastal region was discussed. The primitive pottery culture probably initiated the Jjigae (stew) culture and the production of salt. It can be also postulated that fish fermentation, kimchi fermentation, and cereal alcohol fermentation originated during this period. Soybean culture emerged ca. 2,000 BCE in South Manchuria and the Korean Peninsula. This paper focuses on the role of Korean foodways in the food science and technology development for the sustainable and resilient food systems. We are facing a global food crisis caused by population growth, climate change, and high animal food consumption. Studies on the meat analog and cultured meat are the new trend in Food Science and Technology. The importance of the wisdom learned through the Northeast Asian traditional foods, for example, soybean curd (tofu) and meaty flavor production by fermentation for the research on the novel sustainable and resilient food systems are discussed.

This study was examined that natural seasoning is related to health care and disease prevention through oriental medicinal theory. A typical oriental medicinal theory is the princeple of win-win cooperation between Yin-Yang and Five elements, the old belief is that our body moves in harmony with Yin-Yang and Five elements. From the records traditional books and papers, we would look at the affinity and nutritional relationship between Five taste(Sweet, Salt, Sour, Bitter, Heat and Spicy) and the body with "Sesame" Therefore, several type of Sesame which is represented by natural seasoning, through intake of Five taste because of body affinity, is expected to prolong health life span.

Field tests with carbon fiber heating wire (CFHW) embedded inside concrete slab were performed to present the alternative heating material capable of avoid the adverse effects of traditional de-freezing salt on the structures and environment. The CFHW was inserted into the concrete slab in the shape of 'ㄷ' to improve the heat superposition and the temperature on the surface was measured using iButton. The results showed that the temperature where the CFHW's were faced with each other increased to above zero after 12-hour at outdoor air temperature of $-6^{\circ}C$. Comparatively, the temperature slightly increased where the CFHW was embedded on one side because the heat was not superimposed. Hence, it can be said that the CFHW is a suitable heating material to prevent the concrete road from being frozen.

Salicornia herbacea is a type of salt marsh plant that has been used in traditional medicine to treat several diseases. Isorhamnetin-3-O-glucoside (I3G) and quercetin-3-O-glucoside (Q3G) are major flavonoids in S. herbacea that are known to exert various pharmacological activities. Therefore, our study sought to validate and optimize an HPLC/UV-based analytical method for I3G and Q3G yield quantification, as well as to determine its limit of detection, limit of quantification, linearity, precision, and accuracy. Upon testing a concentration range of 31.5-1.9 ㎍/mL the results exhibited good linearity (r² ≥0.9996 and r² ≥0.9999 for I3G and Q3G, respectively), and the procedure was deemed precise (relative standard deviation of ≤3.19 and ≤3.85%, respectively), and accurate (102.6-105.0 and 92.9-95.2%, respectively). The results showed that our proposed method could be used for rapid I3G and Q3G evaluation in S. herbacea.

The purpose of this study was to investigate the preparation and cooking processes used to prepare Eungi in cookbooks published from the 1700s to the 1900s. 'Eungi' is a thin gruel made of starch powder. Fourteen historical cookbooks were included and investigated for the preparation of ingredients and processing methods. Fourteen types of eungi were identified. Arrowroot eui and kuseonwangdogo eui were found in 『Kyuhapchongseo』 written in the early 1800s, and many types of eungi (i.e. job's tears eungi, arrowroot eungi, sorghum eungi, lotus root eungi) were mentioned in 『Kunhakhoedeung』, but unfortunately, ingredients and cooking methods were not included. 'Eungi' was made by boiling starch powder prepared using the 'subi method', that is, dried after grinding main ingredients such as job's tears using a millstone followed by soaking and settling. Eungi boiled with water or omija water were seasoned with the sugar or honey, and salt. These eungis were used for stomach complaints and hangovers and to promote longevity.

Objectives : To access the safety and efficacy of Black Ginseng (BG), a traditional herbal medicine on hypertension, we examined various parameters involved in the pathogenesis of hypertension. Methods : We made deoxycorticosterone acetate (DOCA;25 mg/kg/3times/weeks for 3 weeks)-induced hypertension Sprague-Dawley (SD) rats. And experiment group was treated with extract of black ginseng (BG;200 mg/kg/day). Results : In results, the weight of experiment group treated with BG was increased compared with normal and control group. And the heart and lung weights of experiment group were decreased compared with control group. The blood pressure and pulse rate of group treated with BG were significantly decreased compared with control group. In addition, BG greatly reduced the levels of aldosterone. These results suggested that BG has suppressive effects on hypertension, and BG has potential as a safe and effective therapeutics for hypertension. Conclusions : The present data show evidences on anti-hypertension activity of BG in an experimental animal system, which can provide further insights into the development of anti-hypertension therapeutic agents.

The ATP related compounds play an important role in a taste of traditional salt-fermented seafoods (Jeotkals). The ATP related compounds were analyzed in the traditional anchovy Jeotkal during fermentation and 11 kinds of commercial Jeotkals by enzymatic method compared with existing HPLC method, In the traditional anchovy Jeotkal, the contents of $ATP{\~}IMP$ decreased during fermentation, while the contents of Hx reached maximum value at 60 days fermentation and thereafter decreased gradually. Uric acid was detected at 30 days fermentation and showed the gentle increment after that. In the commercial Jeotkals, uric acid was detected $14.6{\~}28.4{\%}$ of total ATP related compounds content by enzymatic method, while it was not detected by HPLC method. From these results, enzymatic method is more accurate than HPLC method for analysis of the ATP related compounds in Jeokals.
