  • 콩 가공 부산물인 콩 배아 이소플라본의 생체내 활성을 증가시키기 위하여 LA, LB, LP 등 3가지 유산균을 단독 또는 혼합하여 비배당체화 전환 효율을 증가시키고자 균주의 종류와 접종량, 발효시간에 따른 이소플라본 함량을 분석하였다. 그 결과 균주를 이용한 모든 발효에서 균주를 사용하지 않은 대조군에 비하여 높은 이소플라본 비배당체 전환을 보였고, 발효시간에 따른 비배당체 전환율은 24시간에서 급격히 증가하였고 이후에는 큰 변화는 보이지 않았다. 비배당체화 발효의 최적 균주는 LP균, 접종량은 5%, 발효시간은 24시간 이었다. 대조군의 이소플라본 배당체의 구성은 글리시틴>다이드진>제니스틴 순으로 가장 높은 함량을 나타내었고, 유산균을 접종하여 발효시켰을 때 배당체들은 감소하였고, 비배당체 함량이 증가하였으며, 다이드제인>글리시테인>제니스테인 순으로 45% 이상의 비배당체 전환율을 나타내었다. 특히, 대조군과 비교하여 유산균으로 발효시켰을 때 다이드진의 함량이 가장 크게 감소하였고, 다이드제인 함량이 가장 크게 증가하였다. 소야사포닌의 경우 발효에 의하여 Ab가 급격하게 감소하였고 Ba와 Bb가 증가하였다. 발효액은 pH 3에서 pH 6으로 증가함에 따라 이소플라본 비배당체 함량이 증가하였으며 특히, 다이드제인 함량이 많이 증가하였고, 소야사포닌 함량은 Ab 함량이 급격하게 감소하였고, Ba와 Bb 함량도 소량감소하는 등 발효액의 pH가 발효에 의한 이소플라본과 소야사포닌 함량 변화에 많은 영향을 미치는 중요한 요인중의 하나임을 알 수 있었고, LP균을 이용한 발효로 가공부산물인 콩 배아의 생리활성 증가 및 기능성소재화를 꾀할 수 있을 것으로 생각된다.

  • An image exists in the thought of every subjective person and it exercises its influence over everything, having a great power in the real world. An positive image of the nurse has an influence on her faith, value and confidence, therefore increasing her job satisfaction, helping to upgrade her level of profession of nursing through qualitative nursing service as a result, considering the necessity of such an image when it comes to improvement of the profession, the confirmation of the image is indispensable to its evaluation of a speciality in nursing. This study is intended to help that improvement of the nursing profession in the present so that the total effort in every field of nursing is made and to offer basic material for developing a strategy to improve the image of nurses. This study is designed to investigate such an image descriptively. The subjects include 105 nurses, 60 doctors, 68 office workers, 88 medical engineers, 127 patients and there protectors with a total of 448 adapted with accidental sampling, who work at Y and W general hospital in Chonju. The measuring instrument consists of 40 question, with the researcher amended and made from on of Inja Song(1993), Donsoon Lee(1995), Ilsim yang(1998), and its Cronbach's alpha coefficient is .95. Data were collected from March 1 2000 to March 20, 2000 using self-reported questionnairs, analyzed with SPSS WIN 7.5 after encoding. The results are as follows: 1. Most of the subjects thinks the nursing as a hard, stressful, always busy job(more than 75%), and consider nurses as good-looking, supportive and responsible to co-workers to above average degree($50.0{\sim}74.9%$), especially it shows the idea that nursing is independently academic job and has come to fasten itself upon the public. But it shows below the everage($25.0%{\sim}49.9%$) in regard to self development as a specialist, affection for there job, an association activity, service to the community, high intelligence level and direct given patient nursing service. It also rated low as a recommendable job, independently nursing accomplishment, social position. 2. The nurses, patients and there protectors expressed more positive opinions than doctors, medical engineers, office workers about the image of the nurse(F=18.80, p=.00). This fact indicates that the former group evaluated the image similarly contrary to lowness of the latter. 3. In the study on what influenced upon the image, it defines to 79.8% by direct contact in the hospital or acquaintance with nurses, and 16.3% by mass media. 67.3% answered that they saw the image in a new light through hospitalization, which suggests an important source for the image management originates from caring for the quality of nursing service. Considering the evaluation of the image above, we need strategies to lead a unique professional knowledge and technological development, insurance of professional self-determination, high social position, participation in group activities, dedication to lifetime job, in order that nursing comes to expand as a professional occupation. Also, as for generating more positive images, we must take the quality of nursing service into account and offer and monitor correct information about the expanded role and function of the nurse continuously so that mass media reflect a more accurate image of nurses in general.

  • The purpose of this study was to investigate the relationship between nutrient intakes and blood parameters of cardiovascular function in 40 female college students on self-selected diet in Chungnam. Anthropometric measurements, analysis of dietary intakes and blood composition were conducted. Serum levels of triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, CK-MB, and LDH were measured by biochemical analyzer. The results were summarized as follows. The mean age of the subjects was 22.5$\pm$1.2 years. The weight, height and BMI were 52.4$\pm$7.2kg, 161.3$\pm$5.7cm and 20.2$\pm$2.4, respectively. Daily energy and lipid intakes were 1634.2$\pm$ 437.7kcal and 46.8$\pm$17.0g. And the ratio of carbohydrate, protein, and lipid to energy intake was 59.2 : 14.5 : 26.3. Serum concentrations appeared to be 61.1$\pm$ 24.2mg/dl(triglyceride), 141.2$\pm$330.mg/dl(total cholesterol), 64.8$\pm$ 20.1mg/dl(HDL-cholesterol), 64.1$\pm$ 25.4mg/dl(LDL-cholesterol), 7.2$\pm$3.2IU/l (CK-MB), 107.9$\pm$23.4IU/l (LDH). In the relation between nutrient intakes and serum parameters, vitamin $B_1$ intake showed positive correlation with triglyceride, HDL-cholesterol, and CK-MB, respectively(p<0.001, p<0.05, p<0.05). Vitamin $B_2$intake had positive correlation with triglyceride(p<0.05). And vitamin C intake had negative correlation with HDL-cholesterol(p<0.05). From these results, it is suggested that the intakes of micro nutrients such as vitamin $B_1$, vitamin $B_2$, vitamin C have relation with cardiovascular function in female college students. However, further systematic research is needed to investigate the functions of micro nutrients in healthy persons for prevention of chronic diseases.

  • With the purpose of improving ginsenoside content in adventitious root cultures of Korean wild ginseng (Panax ginseng Meyer), the roots were treated with different dosages of ${\gamma}$-ray (5, 10, 25, 50, 75, 100, and 200 Gy). The growth of adventitious roots was inhibited at over 100 Gy. The irradiated adventitious roots showed significant variation in the morphological parameters and crude saponin content at 50 to100 Gy. Therefore, four mutant cell lines out of the propagation of 35 cell lines treated with 50 Gy and 100 Gy were selected on the basis of phenotypic morphology and crude saponin contents relative to the wild type control. The contents of 7 major ginsenosides ($Rg_1$, Re, $Rb_1$, $Rb_2$, Rc, Rf, and Rd) were determined for cell lines 1 and 3 from 100 Gy and lines 2 and 4 from 50 Gy treatments. Cell line 2 showed more secondary roots, longer length and superior growth rate than the root controls in flasks and bioreactors. Cell line 1 showed larger average diameter and the growth rate in the bioreactor was comparable with that of the control but greater in the flask cultured roots. Cell lines 1 and 2, especially the former, showed much more ginsenoside contents than the control in flasks and bioreactors. Therefore, we chose cell line 1 for further study of ginsenoside contents. The crude saponin content of line 1 in flask and bioreactor cultures increased by 1.4 and 1.8-fold, respectively, compared to the control. Total contents of 7 ginsenoside types ($Rg_1$, Re, $Rb_1$, $Rb_2$, Rc, Rf, and Rd) increased by 1.8 and 2.3-fold, respectively compared to the control. Crude saponin and ginsenoside contents in the bioreactor culture increased by about 1.4-fold compared to that the flask culture.

  • 국내산 밤 일부 품종(단택, 대보, 석추, 옥광, 병고)의 기능성 성분 분석과 이들 물질들의 항산화력 및 밤 추출물이 대식세포 활성에 미치는 영향력을 알아보았다. 국내산 밤 일부 품종의 내피와 과육에서 coumarin, gallic acid 그리고 catechin이 HPLC에 의해 검출되었다. 밤 내피에 가장 풍부한 기능성 성분은 catechin이고 그 다음 gallic acid와 coumarin 순이었으나, 과육에서는 gallic acid만 검출되었다. 따라서 밤의 기능성 성분인 gallic acid와 catechin의 항산화력을 DPPH radical 소거작용과 SOD 유사활성을 통해 알아보았다. Gallic acid과 catechin을 6.0 mg/100 g 처리하였을 때 DPPH radical 소거작용이 각각 69.4%와 38.3%였으며, gallic acid의 DPPH radical 소거작용은 농도 의존적이었다. Gallic acid를 동일한 농도의 catechin과 비교하면 모든 농도 구간에서 catechin보다 gallic acid가 높은 DPPH radical 소거활성을 나타내었다. 그러나 SOD 유사활성은 gallic acid보다 catechin이 높았다. 더하여 밤의 과육, 노란과육 및 흰과육 추출물들이 대식세포 활성에 미치는 영향력을 알아보았다. 병고 흰과육 추출물은 현저하게 대식세포 활성을 증가시켰고, 병고, 단택, 대보 및 옥광의 노란과육 추출물 역시 아무 것도 처리하지 않은 세포와 비교하여 현저히 대식세포를 활성화시켰다. 노란과육 추출물이 흰과육 추출물보다 더욱 더 대식세포 활성을 증가시켰고, 5품종 중 병고가 대식세포 활성을 가장 증가시켰다.

  • Objective: To suggest diagnostic reference levels (DRLs) for dental panoramic radiography in adults and children through the nationwide survey in Korea. Materials and Methods: Two hundred twelve dental institutions on a national basis were visited. The radiographic examination protocols were surveyed and their patient doses at the clinical exposure setting for adult and children (5- and 10-year old) were measured at 244 panoramic radiographic equipment. The measured DAP were analyzed and compared according to age group, the size of hospital, the type of radiographic system, the installation duration of equipment. Results: The mean exposure parameters were 70.1 kV, 9.2 mA, 14.4 second for adult and 66.6 kV, 7.9 mA, 13.8 second for 10-year old child and 65.5 kV, 7.3 mA, 13.7 second for 5-year old child. The mean and third quartile patient DAPs were $138.3mGy\;cm^2$ and $151.0mGy\;cm^2$ for adult, $99.5mGy\;cm^2$ and $104.8mGy\;cm^2$ for 10-year old child and $89.5mGy\;cm^2$ and $95.5mGy\;cm^2$ for 5-year old child. The mean patient dose at the university dental hospital was lower than that at the dental clinic (p<0.05). The mean patient dose of direct digital radiography type was higher than that of film-based type. However, the difference did not show statistically significance. Conclusion: DRLs for dental panoramic radiography in adult, 10- and 5-year old child were suggested to be $151mGy\;cm^2$, $105mGy\;cm^2$, and $96mGy\;cm^2$ in Korea based on this nationwide survey.

  • Transgenic zoysiagrass (Zoysia japonica Steud.) expressing the bar gene inserted in the plant genome has been generated previously through Agrobacterium tumefaciens-mediated transformation. The GM zoysiagrass (event: JG21) permits efficient management of weed control of widely cultivated zoysiagrass fields, reducing the frequency and cost of using various herbicides for weed control. Now we have carried out the environmental risk assessment of JG21 prior to applying to the governmental regulatory agency for the commercial release of the GM turf grass outside of test plots. The morphological phenotypes, molecular analysis, weediness and gene flow from each test plot of JG21 and wild-type zoysiagrasses have been evaluated by selectively analyzing environmental effects. There were no marked differences in morphological phenotypes between JG21 and wild-type grasses. The JG21 retained its stable integration in the host plant in T1 generation, exhibiting a 3:1 segregation ratio according to the Mendelian genetics. We confirmed the copy number (1) of JG21 by using Southern blot analysis, as the transgenic plants were tolerant to ammonium glufosinate throughout the culture period. From cross-fertilization and gene flow studies, we found a 9% cross-pollination rate at the center of JG21 field and 0% at distances over 3 m from the field. The JG21 and wild-type zoysiagrass plants are not considered "weed" because zoysiagrasses generally are not dominant and do not spread into weedy areas easily. We assessed the horizontal gene transfer (HGT) of the transgene DNA to soil microorganisms from JG21 and wild-type plants. The bar gene was not detected from the total genomic DNA extracted from each rhizosphere soil of GM and non-GM Zoysia grass fields. Through the monitoring of JG21 transgene's unintentional release into the environment, we found no evidence for either pollen mediated gene flow of zoysiagrass or seed dispersal from the test field within a 3 km radius of the natural habitat.
