Sneak current is one of the main bottlenecks for dense crossbar array resistive random access memory. This study reports highly non-linear resistive switching characteristic from Ce0.9Y0.1O2/ TiO2 bi-layer (1S/1R device) structure, fabricated by photochemical metal-organic deposition, as a solution for sneak current issue. Ce0.9Y0.1O2 material, possessing oxygen vacancies, was used as a potential barrier as well as oxygen reservoir which rectified the current of low resistance state without an electrical breakdown in 1S/1R device. TiO2 was adopted for resistive switching property, and TiO2 layer having mixed phase (anatase and brookite) showed typical diode switching behavior. The photochemical reaction of photochemical metal-organic deposition process and phase formation were monitored and established using by Fourier-transform infrared spectroscopy and X-ray diffraction, respectively. The 1S/1R device showed highly non-linear resistive switching characteristic, large on/ off ratio of above three orders of magnitude with low operating current.

저용량 Cyclosporine-A와 Diltiazem 병합요법에 의한 신증후군의 관해

김성은,정연순,임학 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.3

Background : Cyclosporine-A (CsA) has been widely used as a treatment of nephrotic syndrome especially in patients with steroid-resistance or steroid-dependence. However, it can be nephrotoxic and its cost might also be a point to be considered. Diltiazem (DZ), one of calcium channel blockers, may have a potential benefit of renoprotection, which decreases acute tubular necrosis of renal transplants. DZ can also be used for reducing CsA dose because it slows down the metabolism of CsA by inhibition of cytochrome P-450 hepatic enzyme. In these points of view, low-dose CsA with DZ combination could be considered as an alternative to nephrotic syndrome treatment. However, such a kind of trial was hardly found so far. The purpose of this study was to evaluate the therapeutic effect of low-dose CsA with DZ in patients with steroid-resistant or steroid-dependent nephrotic syndrome. Methods : Low-dose of CsA (mean 1.7±0.5 mg/kg) and 90 mg of DZ were administered simultaneously to 15 patients of steroid-resistant or steroid-dependent nephrotic syndrome for 6 months with no alteration of dose. Blood pressure, body weight and random urine protein, 24-hour urine protein, serum creatinine, albumin, total cholesterol, and trough level of CsA were analyzed. Results : The random urine protein tended to decrease by CsA treatment. Twenty-four hour urine protein excretion decreased significantly at 6th months of treatment (from 7,211±5,374 mg to 1,094±1,688 mg, n=7, p=0.018). Complete remission was achieved in 10 patients and partial remission in 5 patients. Changes in serum albumin, total cholesterol, hemoglobin, body weight and blood pressure were statistically not significant. Conclusion : Low-dose CsA combined with DZ may be an effective in patients with steroid-resistant or steroid-dependent nephrotic syndrome.

In this paper, when receiving image input from various angles from an electronic medium such as a smartphone, a system for recognizing and translating characters by processing images in the image is presented. The translator designed in this paper processed images using a library called OpenCV. Through OpenCV, the boundary of the image can be found, and the distorted image is corrected. After that, Tesseract-OCR was used to enable the computer to convert the characters displayed in the image into strings. After transforming the image that was not placed forward as a function of OpneCV in the forward direction, Tesseract was applied to the deformed image. Characters in images from various angles were recognized, translated using Google Translation API, and the results were displayed on the image and presented.

The purpose of this study was to investigate the short-term motor memory in continuous and discrete modern dance movements. The subjects were 34 students who was majoring in modern dance in P Arts High School. The task of this experiment were 8 discrete modern dance movements and 8 continuous modern dance movements. Subjects twice viewed sequence 8 movements performed by an expert dance, sequence were viewed in one minute and then immediately recalled by actually performing the dance movements. A T-test was used in order to see whether there exists significant difference between the groups. The reuslts are as follows; (1) Both primacy nad recency effects were apparent. (2) The motor memory of dicrete movements were appeared significant differences(p<.01). Experts and over than 5 years dance experience group were greater than novices and less than 2 years dance experience group. (3) There was no significant difference among the groups in the continuous movements.

운동학습 이론의 무용수업 적용에 관한 연구

성은지 韓國舞踊敎育學會 1994 韓國舞踊敎育學會誌 Vol.4 No.-

Dance is the art form which is expressed One's thought and feelings through the body. for the artistic goa, dancers have to train their body scientifically and efficiently. If dancers practice economically, they can invest their energy and time in choreography or their new pieces along with aesthetic elements. Motor learning theory is regarded as an efficient method of body training. Yet many dance teachers have not believed that this method is appropriate to their dance class, so they depend on customary way of teaching. In this point of view, it is necessary for efficiency of dance lessons to review the researchs of dance used motor learning theory.

폐경후 여성의 비만도에 따른 영양상태와 항산화능에 관한 연구

승정자,김은영 대한비만학회 2003 The Korean journal of obesity Vol.12 No.3

연구배경: 여성은 폐경을 맞이하면서 호르몬의 변화 등으로 인해 비만 발생률이 높아지며, 그로 인해 만성퇴행성 질환 발병 위험을 초래한다. 이에 폐경 후 비만 여성에서 혈중 항산화효소 활성 및 혈중 지질양상을 비교하고자 하였다. 방법: 폐경 후 여성 60명을 대상으로 2001 국민건강 영양조사의 체질량지수 85th percentile 이상인 대상자를 비만군(27명), 그 이하는 대조군(33명)으로 분류하였다. 신체계측과 식이섭취조사, 혈액 채취를 실시하였고, 항산화효소인 superoxide dismutase, glutathione peroxidase, total antioxidant 활성을 측정하였다. 결과: 연구 차상자의 평균 연령은 비만군이 65.4세, 대조군이 64.2세로 두 군간에 유의적인 차가 없었고, 비만군의 체중(p<0.001), 체질량지수(p<0.001), 허리-엉덩이 둘레비 (p<0.001), 체지방률(p<0.001)이 대조군에 비하여 유의적으로 높았다. 열량 섭취량은 1일 평균 비만군이 1551.4 kcal(권장량의89.4%), 정상군이 1516.1 kcal (권장량의 85.9%)로 두 군간에 유의적인 차이가 없었고, 영양소 섭취량도 두 군간에 유의적인 차이를 보이지 않았다 식품군별 섭취량 조사 결과 비만군의 감자 및 전분류(p<0.01), 난류(p<0.01)의 섭취량이 대조군보다 유의적으로 높았다 비만군의 심혈관계질환의 위험인자와 관련된 지표인 혈청 총 콜레스테롤(p<0.05), 중성지방(p<0.05)의 수준도 비만군이 대조군에 비하여 유의적으로 높았다 항산화효소 활성을 분석한 결과, SOD, GPx, TA 활성은 두 군간에 유의적인 차이가 없었다. 혈액지표간의 상관관차를 분석한 결과 혈중 총 콜레스테롤과 SOD가 양의 상관관계 (p<0.05)를 보였다. 결론: 비만군은 혈청 총 콜레스테롤과 중성지방의 수준이 대조군보다 높아 심혈관계질환의 위험도가증가한 것으로 나타났으며, 차상자의 혈청 총 콜레스테롤은 SOD 활성과 유의적인 양의 상관관계 (p<0.05)를 보임으로써 비만도 증가에 따른 혈중 지질 수준의 변화는 항산화능의 변화와도 관련이 있을 것으로 보여진다. Background: Increases in the number of obese population is an international issue, and Korea is not an exceptional case. In postmenopausal women changes in hormonal profiles may raise a problem of obesity. Obesity is correlated to chronic degenerative diseases and the antioxidant status. The purpose of this study was to compare the antioxidant enzyme activities and serum lipid of obese postmenopausal women to those of non-obese subjects, and investigate the relationship among nutritional status, BMI, and antioxidant enzyme activities in postmenopausal obese women. Methods: In this study, we classified the subjects in to the obese postmenopausal women(n=27) and non-obese (n=33) according to their BMI, and measured dietary intakes, serum lipid, SOD (Superoxide dismutase activity), GPx (Glutathione peroxidase activity) and TA (Total antioxidants capacity). Results: The average age of obese and non-obese were 65.4 yrs and 64.2 yrs, respectively and there was no significant difference. Body weight (p<0.001), body mass index (P<0.00l), waist-hip ratio (p<0.001) of obese were significantly higher than those of non-obese. The mean daily intake of energy in obese and non-obese subjects were 1551.4 kcal (89.4% of RDA) and 1516 kcal(85.9% of RDA), respectively and there was no significant difference. The mean daily nutrient intakes of obese was not significantly from those of non-obese subjects. The obese consumed significantly greater quantities of potatoes (P<0.0l) and eggs (P<0.01) compared those consumed by non-obese. Serum total cholesterol (p<0.05), triglyceride (P<0.05) of obese were significantly higher than those of non-obese. There was no significant difference in SOD, GPx, TA activities. A significantly positive relationship was present between total cholesterol and SOD (p<0.05). Conclusion: Obese postmenopausal women had higher serum total cholesterol and triglyceride than those of the non-obese. Obesity is associated with elevated antioxidant enzyme activities. And that perdisposes the cardivovascular disease to oxidative stress.
