裵光星,宋相鎬,鄭圭和 慶尙大學校 1991 論文集 Vol.30 No.2

잎파래(Enteromorpha linza) 葉體의 無菌化와 葉體에서 分離한 原形質體의 培養에 關한 몇가지 條件을 決定코자 하였다. 洗劑로 葉體의 附着微生物을 除去하기 爲해서는 0.1%液으로 15∼20分間 洗 하는 것이 效果的이었으며, 組織內部의 微生物은 1% KI-I2液으로 2.5∼5分間 處理하여 抗生劑 2%가 添加된 培地함으로서 除去가 可能하였다. 葉體의 原形質體는 2% AAP가 添加된 各種酵素液으로 容易하게 분리할 수 있었다. 原形質體의 無菌培養을 爲한 抗生物質의 添加濃度는 1.5%程道가 適當하였으며 照度는 2000lux以上일 境遇培養에 큰 影響을 미치지는 않는 傾向이었다. Basic studies for obtaining the axenic tissue, isolation and culture of protoplasts of Enteromorpha linza have been attempted. Treating with 0.1% detergent for 15-20mins were effective for cleaning the collected tissue. Exposure the tissue to a 1% KI-I2 solution for 2.5-5.0 mins subsequently culture them in the medium containing 2.0% antibiotic materials were good for inhibition of bacterial growth as well as enzyme solutions composed of abalone acetone powder, cellulase R-10, and driselase. The 2.0% antibiotic medium was good for the suppression of bacterial growth in protoplasts culture. The development of protoplasts was not largely influenced by the light strength and photoperiods.

최근들어 기업 및 개인이 구축한 홈페이지의 수와 인터넷 사용자는 급속히 증가하고 있다. 점을 기반으로 하는 인터넷의 사용으로 멀티미디어를 이용한 다양한 정보제공과 지구촌의 정보교환 창구로서의 역할을 수행하고 있어 정보화 사회를 실감할 수 있는 시대에 와 있다. 이러한 홈페이지는 즉시성과 보존성을 지닌 정보제공을 목적으로 하면서, 정보전달의 방법이 시각적인 것에 의존하는 부분이 많으므로 홈페이지 제작의 기획단계에서 그래픽적인 요소의 분석이 우선적으로 고려되어 그 사이트의 성격을 충분히 보여줄 수 있어야 한다. 그러므로 홈페이지를 구성하는 레이아웃, 서체, 색채, 정보의 제공방법 등의 제반요소는 전체 사이트의 이미지를 결정하는 표현수단이므로 중요하게 다루어져야 한다. 또한 인쇄매체에서 이루어지는 전통적이고 일반적인 그래픽처리와는 달리 디지털데이터와 모니터에서의 표현이라는 전달매체의 특성상 기존의 디자인 요소들과는 다른 접근방식이 요구된다고 하겠다. 본 연구는 한국과 일본의 대학 홈페이지를 대상으로 기본색채, 사용 서체의 종류와 크기 및 레이아웃을 대상으로 디자인을 비교하여 보았으며 이 분석내용이 향후 본 대학의 홈페이지의 질적인 향상을 위해 업데이트 할 때 홈페이지 디자인의 객관적인 분석자료로서 활용되었으면 한다. Recently, the number of homepages of companys and individual are rapidly increasing. We can feel the ages of global information exchange by using multimedia which based on the web technology. These pages purpose on the instantability and preservation. Since these pages depend heavily on the visuality, they need consider the graphical aspects of them from the early stage of the designing. Since most of these kinds of homepages made for the purpose of information provision are graphics, we should analyze graphical aspects when we design them. Therefore, we should pay much attention to layout, font and color of the homepages. We also should adopt different approaches for the special transmission media of digital data and computer monitor which are very different from the traditional ones. We estimate the usage frequency of basic colors, kinds of fonts and their sizes on homepages of the Korean and Japanese colleges (and universities). We classify these kinds of homepages and find the design tendency for the future web page updating.

Renal angiomyolipoma is an uncommon benign tumor of the kidney, with or without tuberous sclerosis, which is composed with mixture of adipose tissue, smooth muscle and blood vessel. Angiomyolipoma without tuberous sclerosis is usually solitary and unilateral, and is predominent in middle aged women. Its clinical and radiologic features are similiar with renal cell carcinoma, so its preoperative daigonosis is difficult, But recently, nephrotomography, ultrasonography and computerized tomography are helpful in diagnostic procedures. Herein we present a case of renal angiomyolipoma without tuberous sclerosis, in 27 years old male.

The porcine reproductive and respiratory syndrome virus was inoculated into swine tracheal organ culture. The ballooning degeneration of the tracheal ciliated epithelium and a decrease of ciliary activity from the tracheal organs infected with PRRS virus were observed one day post-infection(PI). Tracheal epithelium showed degeneration and focal necrosis 2 days PI. Epithelial necrosis and loss of cilia and epithelial cells became more severe 3 and 4 days PI. An entire loss of cilia and epithelial cells were recognized 4 days PI, however, control tracheal organs were normal during the period of the experiment except a little decrease of ciliary activities with time..

Ozone is very effective in acute and chronic viral disease as a virucidal agent and in improving the general health of the animals. The effects of ozonized water supply against Cryptosporidium baileyi was studied in 2-day-old chicken. After oral inoculation of chicken with 1×10^6 oocysts, ozonized water(0.5ppm) and tap water were supplied to experimental and control group, respectively. The prepatent period of both group was 6 days postinoculation(PI). The patent period of experimental group was shorter(6-18 days) than that of control group(6-22 days). The number of oocysts in the feces were maximum on days 11 PI, indicating 1.99×10^6 oocysts/experimental chicken and 6.00×10^6 oocysts/control chicken. The number of discharged oocysts during experimental period was higher in control group than that of experimental group. In the view of febric bursa sections on 7 days PI, the number of endogenous development of C baileyi was smaller in experimental group that in control group. This results indicate that the autoinfected sporozoite were damaged by ozone. The ozonized water supply to chickens is alleviation cryptosporidiosis.

Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.
