  • This study was performed to investigate the effects of cell-wall broken spores of Ganoderma lucidum on the lipid accumulation and body weight reduction in C57BL/6J mice. Six-week-old C57BL/6J mice were randomly divided into 5 groups and assigned to one of these groups; normal chew diet(Nor) group, high-fat diet(HFD) group, HFD plus spores of Ganoderma lucidum 800 mg/kg/day (HFD + GS/B) group, HFD plus cell-wall broken spores of Ganoderma lucidum 400 mg/kg/day (HFD + BGS/A) group and finally HFD plus cell-wall broken spores of Ganoderma lucidum 800mg/kg/day (HFD + BGS/B). The experimental groups which were treated oral co-administration with cell-wall broken(or original) spores of Ganoderma lucidum and HFD significantly attenuated accumulative body weight gain, compared with HFD group. Administration of these experimental materials also resulted in significant reduction not only the serum levels of total cholesterol, homocysteine but also the lipid accumulation in liver tissue. But in the almost of results the cell-wall broken spores of Ganoderma lucidum were evaluated superior than the original one. These results indicate that cell-wall broken spores of Ganoderma lucidum may inhibit the lipid accumulation in blood as well as liver tissue. Therefore it may be a valuable candidate for the therapy preventing obese induced hyperlipidemic symptoms.

  • War against Japanese(1592-1599) and war against Manchurian(1636-1637), which had been occurred in Korean Peninsula throughout the history, and frequent trade with foreign countries since $18^{th}$ century have led to a distribution of foreign food into Korea. Several examples for this include tomato, apple, watermelon, maize, pea, cowpea, peanut, potato from China and red pepper, pumpkin, and sweet potato from Japan. Since these foods had been brought into Korea, they have been cultivated suitable for Korea's climate and land. Foreign foods with a few exceptions tend to have high calories. For instance, along with potato and sweet potato, pumpkin is considered a high-calorie food containing lots of starches as it becomes ripening. This helped a wide spread of the foreign foods across the nation where intake of high-calorie foods was critical for Korean people's nutrition at that time. Among those foods introduced from foreign countries, red pepper had a greatest impact on the dietary life-style of Chosun Dynasty. The use of red pepper has been greatly expanded from main ingredient to seasoning and garnishing in various forms of red pepper such as red pepper paste, red pepper powder, and thick soy paste mixed with red pepper. Red pepper was made eating habits is hot besides dye red colored to traditional food, because steaming and boiling is frequently cook method, fermentation food also food color is achromatic therefore food color is and mixture with red pepper, picked fish and chinese cabbage new kimchi culture came into being.

  • Effect of allylisothiocyanate on the enzyme activites including malate degydrogenase, isocitrate dehydrogenase, NADPH and acetyl CoA which were related to aflatoxin production of Aspergillus parasticus R-716 were invetigated. The activities of malate dehydrogenase (EC.1.1.1.37), isocitrate dehydrogenase (E.C.1.1.1.42) and NADPH oxidase (E.C.1.6.99.1) indicated relatively high in the 50 ppm allylisothiocyanate-added-culture. In contrast, the activity of acetyl CoA in the 50 ppm allylisothiocyanate-added-culture showed rather lower level through the cultivation.

  • Animal cell culture media are usually supplemented with fetal bovine serum (FBS); however, the use of FBS presents certain problems including high cost. By using an adaptation process and the addition of silkworm hemolymph, the FBS concentration can be reduced without causing a significant decrease in cell growth.

  • Cow's liquid manure (CLM), an animal waste, was treated by a batch algal culture to remove inorganic nutrients. CLM used in this study was especially high in concentrations of inorganic nitrogen and phosphorus. The optimum dilution ratio of the CLM for maximum algal growth was 1:25. Ninety five percent of inorganic nitrogen and 100% of inorganic phosphorus were removed from the CLM with a dilution ratio of 1:25.

  • This study aims to draw up comprehensive ethical management practices so that companies can be reborn as high-quality companies not only at the level of management efficiency but also at the level of corporate integrity. -The main focus of in this study is as follows: To curb corrupt practices in the corporate sector, it is necessary to strengthen the monitoring function and accountability system of audits (internal audits, full-time audits, audit committees, external audits). In order for these system improvements to be made reliably, it is necessary to periodically measure and evaluate employee satisfaction with the overall personnel system.

  • 이 연구에서는 해산어의 종묘 생산에 필요한 대량 배양용 로티퍼, Brachionus rotundiformis의 종 보존 방법으로서 무균 로티퍼의 이용을 검토했다. 로티퍼는 개량형 항생제 혼합액 AM9을 사용하여 무균 처리한후, 무균 Nannochloropsis oculata를 먹이로 공급하여 연속 유지 배양했다. 각각 다른 시기의 3회 (trial 1, 2 and 3)에 걸친 로티퍼 배양결과, 무균 배양 (axenic culture)에서는 비교적 안정적인 증식을 보인 반면, 유균 배양 (non-axenic culture)에서 로티퍼의 증식은 불안정적으로 각 시기에 따라서 심한 증식의 차이가 관찰되었다. 이 결과는 유균 배양에서 로티퍼의 증식에 직접적으로 악영향을 미치는 박테리아가 무균 처리과정을 통해서 제거되었음을 증명한다. 로티퍼 무균 배양 방법의 일반화 또는 대량 배양용 로티퍼의 씨앗으로서의 무균 로티퍼의 이용은 로티퍼의 안정 배양은 물론 유용 수산 생물의 대량 폐사를 일으키는 원인 생물을 사전에 제거할 수 있는 유효한 방법이 될 수 있다고 생각된다.

  • The purpose of this study was to examine the cases of the family head's costume culture and to apply them to field experience education of adolescent's home economics subject. To examine the family head's costume culture, women in the family head in the Hampyeong area, Jeollanam-do were selected and interviewed. The focus of examining the family head's costume culture was on the life story of the family head, the reason to wear or possess such costume, and a motive of making. The findings of the head family's costume culture suggests that the head family of the Mos of Hampyeong had unique shroud making and custom. Also it was found that the eldest daughters-in-law of the Lees of Hampyeong have horizontally exchanged the information of the family head's costume with village women of the same family. They have initiated their costume culture directly through their daughters and it had the great influence on after-ages. The learning program for youth to experience the head family's costume culture consisted of four subjects:(l)Educating the family head's traditional living culture including etiquette training, (2)head family village walk, (3)experiencing the family head's clothes life including natural dyeing and sewing, and (4)a field trip of Hampyeong Local Life Culture Museum. For a model experience of the family head's costume life culture, three families with middle and high schoolers participated in 8- hour experience learning program. To examine the effect of learning program to experience the family head's costume culture, youth and their parents who participated in the program were asked open-ended questions, which included the content validity of experience learning, impressive experience, model experience level(difficulty), and expected effect after a model experience. As a result, their responses were found positive.

  • Traditional culture technology of medicinal plants mainly depends on the field culture, which has many problems. With progress of modern culture technology, it has become possible to produce valuable secondary metabolites from medicinal plants. In this paper, we discuss about the pigment and saikosaponin production from too medicinal plants, Carthamus tinctorius and Bupleurum falcatum, through bioreactor culture system. A two-stage bioreactor culture system was established for the production of yellow and red pigments and saikosaponins by cell suspension cultures of Carthamus tinctorius and Bupleurum falcatum. In Carthamus tinctorius, balloon type airlift bioreactors and column type airlift bioreactors were employed for the tell culture and for the pigment production, respectively. The greatest pigment production was obtained on White medium supplemented with 4 mg/L kinetin, high levels of sucrose concentration and photosynthetic photon flux. In Bupleurum falcatum, adventitious roots were cultured in balloon type airlift bioreactors and the root growth was greatest on SH medium containing 5 mg/L IBA and 0.2 mg/L kinetin. HPLC analysis showed that the contents of main active saikosaponins a, c, and d in adventitious roots were almost the same as those in field cultured root.

  • LSM을 이용하여 KA112 균주의 고농도 배양을 시도하였다. Separator로는 hollow fiber를 사용하였고 reactor로는 Celligen을 이용하였다. Wroking volume 1리터로 10일간 배양하여 최고 세포농도가 회분식 배양에 비하여 10배 이상 증가한 $2.1\times10^7$ cells/ml이었고, 항체의 농도는 4.5배 정도 높았다. 최고 feed rate에서 항체생산속도는 회분식 배양보 다 9배 높았으며 배양 중 glucose농도가 Ig/e 이상일 때 specific productivity가 증가하였고, 1 g/6 이하얼 때 세포성장은 영향을 받지 않으냐 spe­c cific prodictivity는 감소하였다.
