This study was done to know the effects of Palmijihwangtang(八味地黃湯) on the cytotoxic activity of NK cells, the phagocytic activity of macrophages, the antibody production of B cells, and delayed-type hypersensitivity reaction by T cells in the mouse. The results were as follows. 1. The administration of Palmijihwangtang enhanced the cytotoxic activity of NK cells against YAC-1 cells. 2. The administration on Palmijihwangtang increased the production of reactive oxygen intermediate(ROI) production from macrophages without any effect on phagocytic activity. 3. The administration of Palmijihwangtang decreased the delayed-type hypersensitivity against dinitrochlorobenzene without affecting T cell subtypes. 4. The administration of Palmijihwangtang increased the antibody production against sheep red blood cells. The above results suggest that Palmijihwangtang could be used for the prevention and treatment of the diseases caused by the abnormalties of the body's immune functions.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

김은영, 박봉주, 오명민 忠北大學校 農業科學硏究所 2012 農業科學硏究 Vol.28 No.3

In this study, the availability of pig slurry composting and biofiltration (PSCB) solution as an alternative for synthetic nutrient solution was determined by monitoring the growth and phytochemicals of lettuce (Lactuca sativa L. cv. ‘Salanova’). This study was conducted from 16 September 2011 to 31 October 2011. PSCB solution treatments were consisted of 1 time dilution (52N), 13 times dilution (4N), 26 times dilution (2N), and 52 times dilution (1N) which were based on the nitrogen concentration of a commercial liquid fertilizer for leafy vegetables (control). Subirrigation system was used to cultivate lettuce plants in pots containing commercial growing medium. As a result, all growth characteristics were the highest at control. Among PSCB treatments, PSCB 52N induced severe growth disorder at 28 days after transplanting (DAT) probably due to too high salinity. PSCB 1N also retarded the growth of ‘Salanova’ lettuce plants. This may be caused by high pH and/or imbalanced other mineral concentration except nitrogen of PSCB solution. In contrast, polyphenolic compounds with antioxidant properties were more abundant in lettuce with PSCB solution than control. However, further study is required to determine the certain factors of PSCB on the induction of phytochemical biosynthesis pathway. In conclusion, additional strategies should be developed to use PSCB solution as nutrient solution in greenhouses.

After 14 days from planting, Shenyang cultivar was possible to harvest in 20℃ cultured by Hyponex and by tap water.

The Computer Algebra Systems in Mathematics Education : A Review of Recent Research

Kwon, Oh-Nam,Shin, Eun-Ju,Shon, Bo-Kyung 이화여자대학교 교과교육연구소 2001 East west education Vol.18 No.-

This study examines the potential role for Computer Algebra Systems(CAS) in such an educational context, particularly their potential to get students more engaged in the learning of mathematics as well as to reduce the "strangle hold" of prerequisite algebraic skills, in courses such as functions, introductory calculus. What is the present status of and near-future outlook for computer algebra in Korean secondary schools? The answer that arises from this review of available fact is: bright with promise, but still dim. Several recent developments have set the stage for an acceleration in the dissemination rate for CAS to high schools. However, this review of some past and present conditions indicates that many years will pass before computer algebra is impacting high school mathematics as much as hand-held calculators are doing now.

임은영,강민수,오명주,정태성,정성주 한국어병학회 2003 한국어병학회지 Vol.16 No.3

감성돔 (Acanthopagrus schlegeli)의 비장에서 주화세포인 BSBS를 확립하고 세포의 특성을 검사하였다. BSBS세포는 60회 이상의 계대배양이 가능하였고 형태학적으로는 상피성 세포였다. 세포는 20℃, 10%의 FBS가 든 L-15배지에서 배양하는 조건에서 잘 자랐다. BSBS세포는 해양버나바이러스 (MABY Y-6), 잉어의 봄바이러스병바이러스 (SVCV), 넙치의 랍도바이스(HIRRV)와 연어바이러스 (CSV)를 접종했을 때 세포변성효과가 나타났다. 새로 확립된 주화세포는 앞으로 많은 바이러스병의 연구에 유용하게 사용할 수 있을 것으로 생각된다. A stable cell line, BSBS (black seabream spleen), was established from the cells in spleen of black seabream, Acanthopagrus schlegeli, and characterized. Subculture maintained more than 60 passages and mophologically, BSBS cell was epithelioid cell. The cells grew optimally at 20℃ in Leibovitz's L-15 medium supplemented with 10% fetal bovine serum with incubation temperature of 20℃. BSBS cells supported the growth of marine birnavirus (MABV Y-6), chum salmon reovirus (CSV), spring viremia of carp virus (SVCV) and hirame rhabdovirus (HIRRV). Thus, the new cell line may be useful for studying wide range of fish viruses.

이은주,오창석 충북대학교 컴퓨터 정보통신 연구소 1997 컴퓨터정보통신연구 Vol.5 No.1

This paper presents an ATM based transport architecture for next-generation multimedia services in personal communication networks(PCN). Multimedia services via wireless networks are motivated by an anticipated demand for wireless extensions to future broadband networks. An ATM based wireless network concept is explored as an architectural viewpoint for supporting B-ISDN services. The proposed system uses a hierarchical ATM switching network for interconnection of PCN microcells, each of which is serviced by high-speed, shared access radio links based on ATM-compatible cell relay principles. Design issues related to the physical layer, media access control(MAC) layer and data link layer of the ATM-based radio link are discussed, and preliminary technical approaches are identified in each case. Also, this paper concludes with a brief view of related supporting scenario for a seamless wired plus wireless multimedia networking environment.
