Features and Properties of $YBa_2$$Cu_3$$O_{7-x}$ Films Grown on SrTi$O_3$ by High Frequency PLD

Shi, D.Q.,Ko, R.K.,Song, K.J.,Chung, J.K.,Choi, S.J.,Park, Y.M.,Shin, K.C.,Yoo, S.I.,Park, C. The Korean Superconductivity Society 2003 Progress in superconductivity Vol.5 No.1

YBCO films were deposited with various thicknesses from 100nm to 1.6$\mu\textrm{m}$ on single crystal $SrTiO_3$ substrates by pulsed laser deposition (PLD). The effects of different deposition conditions, especially different deposition rates by means of changing the pulsed laser frequency up to 200Hz, on the J$_{c}$ value were studied. For YBCO film with the thickness of 200nm, the $J_{c}$ value of $2.1MA/\textrm{cm}^2$ has been achieved under the high deposition rate of 3.2nm/s (190nm/min). The $J_{c}$ can be maintained greater than $1M/\textrm{cm}^2$ with the thickness less than 1$\mu\textrm{m}$. The X-ray analysis was used to examine the texture, crystallization and surface quality. The SEM was employed to analyze the surface of YBCO, and it was shown the surface of YBCO film became rougher with increasing the thickness. There were many large singular outgrowths and networks of outgrowths on the surface of YBCO films which lowered the density of thick YBCO film. The outgrowth network was probably the a-axis YBCO corresponding to XRD $\theta$-2$\theta$scan and $\chi$-scan which were used to characterize a-axis orientation of YBCO film. The reason for J$_{c}$ declining with increasing the thickness was studied and discussed.sed.

Purposes :The purposes of this study was to investigate the self-managing status according to the life styles and the diabetic knowledge of early adulthood. The subjects in this study were 240people, the early adult aged twenties to thirties living in the metropolitan area. Data were collected by using self-administered questionnaires that measure about the knowledge of diabetes; the dietetic behavior; the knowledge of diet; the exercise behavior; the knowledge of exercise. Descriptive statistics, t-test, ANOVA, and correlation were used for data analysis. Result :1. At the knowledge of diabetes degree based on the general character, the subjects who had experiences of diabetic education have higher degree of the diabetic knowledge. 2. At the knowledge of diabetes degree according to the life style, the subjects who have regular diet are appeared highly. Also the subjects who don't take much food of animal origin have higher degree. 3. At the knowledge of diet based on the life style, the subjects who don't keep three times meals a day are appeared highly. Also the subjects who have regular diet have higher degree. 4. At the knowledge of exercise according to the life style, the subjects who take extra nutritions 3-4 times a week are appeared highly. Although the subjects tend to know about dietary, exercise and health management, it showed that they actually don't perform what they know in their everyday of life. The reason for this could be the lack of perceived seriousness about diabetes mellitus. Thus as nursing professionals, we should provide them proper health education and support. Moreover, advanced research on the empowerment is warranted.

본 연구는 자체 제작한 다이 측 비드가 설치 된 드로잉 금형을 이용하여 SUS 304, 6:4 황동 판재를 드로잉 가공하여 생산된 제품의 치수변형 특성을, 비드를 설치하지 않은 자유 드로잉 하여 얻은 제품과 비교하였다. SUS 304 판재의 경우, 비드를 설치하여 드로잉 한 경우는 늘어난 길이의 변화가 연속적으로 증가하고 있고, 비드를 설치하지 않은 경우는 마지막 부분에서 다시 회복상태를 보였다. 그 원인은 드로잉 비드로 인하여 적정량의 유입으로 일정 비율로 늘어난 것이라고 볼 수 있다. 6:4 황동 판재의 경우는 비드를 설치한 경우의 치수 변형값이 비드를 설치하지 않은 경우보다 안정함을 보여주었다. In this research, properties of SUS 304 and 6:4 brass products produced by die bead-drawing mold were compared with those of products drawed without bead. In the case of bead-SUS-plate, variation of incremental length progressively increases, while, in the case of no bead-SUS-plate, recovery appeared at the final-part. The reason of this difference is considered as proper insert of metal-plate on the basis of bead. Bead-6:4 brass-plate showed more stable data than no-bead die case although it did not show recovery in final-part.

만기파종에서 수확시 숙기가 사일리지용 옥수수의 사초수량과 품질에 미치는 영향

고한종,박형수,김수곤,김종덕,권찬호,김종관 한국동물자원과학회 2002 한국축산학회지 Vol.44 No.2

옥수수를 호밀과 조합한 연간 2모작의 작부체계하에서는 옥수수의 파종시기가 5월 중순이후로 지연된다. 따라서 본 시험은 전작물이 호밀 때문에 옥수수의 파종시기가 5월 21일로 지연되었을 때 건물수량과 품질을 극대화 할 수 있는 적정 수확시기를 결정하기 위하여 수행하였다. 사일리지용 옥수수는 서울대학교 부속목장에서 5월 21일에 파종하고, 수확은 8개의 다른 숙기에서 수확하였다. 수확시 숙기는 수포형성기(출사후 16일), 유숙기(20일), 유숙후기(26일), 연호숙기(28일), 황숙초기(33일), 황숙중기(38일), 황숙후기(44일), 및 생리적성숙기(53일)로 하였다. 황숙초기에서 황숙후기의 전식물체 건물률은 29.0∼38.5%로 사일리지 생산에 가장 적합하였다. 건물 및 가소화영양소총량(TDN) 수량이 최대인 시기는 황숙중기로 각각 14,831 및 10,675㎏/ha 이었다. 숙기가 진행됨에 따라 전식물체의 ADF 함량은 35.4%에서 22.1%로 감소하였고 NDF 함량 또한 63.8%에서 46.0%로 감소하였다 (P<0.05) ADF 및 NDF 함량의 감소는 옥수수의 부위별 함량 변화와 관련이 높다. 즉 숙기가 진행됨에 따라 옥수수의 부위중 암이삭은 증가하고 경엽은 상대적으로 감소하였다. ADF 함량에 의해 계산된 비유정미에너지(NEL) 및 TDN은 경엽의 경우에는 황숙초기까지는 감소하고 그 이후에는 증가하였으나, 종실과 전식물체의 NEL 및 TDN은 숙기가 진행됨에 따라 유의적으로 증가하였다. In vitro 건물소화율은 숙기가 진행됨에 따라 경엽은 61.1%에서 49.7%로 감소한 반면 전식물체는 58.3%에서 65.7%로 증가하였다(P<0.05). 이상의 결과로 미루어 볼 때 만기파종시 최대건물수량과 품질을 가진 사일러지용 옥수수를 생산하기 위해서는 황숙중기(1/2 milkline) 에서 황숙후기(2/3 milkline) 사이에 수확하여야 한다. 그리고 이때 출사후일수는 38일에서 44일 사이였다. The corn (Zea mays L) planting data in a double-cropping system is delayed until mid-May due to delayed rye harvest on May. This experiment was conducted to determine the optimum harvesting time for high yield and the best quality of silage corn at late planting date after harvesting winter rye. Coms were planted on 21 May and harvested at eight different maturity stage at Seoul National University Experimental Livestock Farm, Suwon in 1997. Maturities were B (blister; 16 days after silking), M (milk; 20 days), LM (late milk; 24 days), SD (soft dough; 28 days), ED (early dent; 33 days), FD (full dent; 38 days), LD (late dent; 44 days) and PM (physiological maturity; 53 days) stages. The percentage of whole plant dry matter (DM) showed optimum range for silage making (29.0 to 38.5%) when corn plant was harvested at between ED and LD stages. Maximum whole plant DM (14,831 ㎏/ha) and total digestible nutrients (TDN) yields (10,675 ㎏/ha) reached at full dent stage. The percentage of whole plant acid detergent fiber (ADF) was decreased from 35.4 to 22.1%, and that of neutral detergent fiber (NDF) was also decreased from 63.8 to 46.0% as harvest stage progressed. These changes in chemical compositions were associated with changes in plant part composition. A progressive increase in total ear, and the decrease in stover portion in the plant were observed with advance in harvest stage. Calculated on net energy for lactation (NEL) and TDN values based on ADF percentage of stover plant decreased by ED stage and then increased by PM stage. But NEL and TDN values of ear and whole plant increased as harvest stage progressed. While in vitro dry matter digestibility of stover was decreased from 61.1 to 49.7%, whole plant was increased from 58.3 to 65.7% as maturity advanced (P<0.05). The results of this study indicate that corn can be harvested for silage at full(1/2 milkline) and late dent (2/3 milkline) stages for maximum yield and optimum quality at late planting. And days after silking at late planting was 38 and 44 days.

PURPOSE : This study purposed to examine the relation between nursing college students' major satisfaction and their nursing professionalism. METHOD : We collected data from 197 nursing students at a college in Seoul using a structured questionnaire from the 6th to 13th. The collected data was analyzed by SPSS 17.0. RESULT : 1. The mean score of major satisfaction was 3.54±49 and that of nursing professionalism was 3.52±46. Among the sub-areas of major satisfaction, satisfaction with career investigation was highest. In addition, among the sub-areas of nursing professionalism, the specialty of nursing was highest. 2. Major satisfaction was higher in those from the Department of Natural Science, with a nurse in their family members and it was also significantly different according to the motive for choosing nursing. Nursing professionalism was higher in those with a nurse in their family members and it was also significantly different according to the motive for choosing. 3. A statistically significant positive correlation was observed between the subjects' major satisfaction and their nursing professionalism. The sub-area of major satisfaction in the highest correlation with nursing professionalism was 'satisfaction with perception', and the sub-area of nursing professionalism in the highest correlation with major satisfaction was 'professional self-concept' CONCLUSION : A significant positive correlation was observed between major satisfaction and nursing professionalism, and this raises the necessity for maintaining high major satisfaction so that nursing students may establish positive nursing professionalism through their college study.
