Purpose: This study aimed to explore the distributions of nurse staffing grades and to report changes in staffing grades in general wards and adult and neonatal intensive care units(ICUs) by hospital type and location. Methods: Data collected from the Health Insurance Review and Assessment Service were analyzed. Nurse staffing was categorized from grades 1 to 6 or 7 for general wards, 1 to 9 for adult ICUs, and 1 to 4 for neonatal ICUs based on the nurse-to-bed ratio. Results: The staffing grade for the general wards improved during 2008-2016 in 69.8% of the tertiary hospitals, 58.5% of the general hospitals, and 31.7% of the non-general hospitals. The adult ICUs at tertiary hospitals exhibited a greater improvement in staffing grades (48.8%) than did those of general hospitals (44.2%) during 2008-2015. Tertiary hospitals in non-capital regions showed a greater improvement than those in the capital region. The majority of neonatal ICUs (67.1%) had no change in the staffing grade during 2008-2015. Conclusion: Improvements in nurse staffing differed by hospital type and location. Government policies to improve nurse staffing in non-tertiary hospitals and those in non-capital regions are required to reduce variations in nurse staffing.

본 논문에서는 컴퓨터 프로그래밍 수업에 형성 평가를 여러 차례 적용하여 가산점을 부여하는 경우 학습자들의 학습 의욕과 성적 향상도에 어떤 영향을 미치는지를 연구하였다. 비교 분석을 위해 형성 평가를 적용한 그룹과 적용하지 않은 학습자 그룹의 성적 향상도를 비교하였으며, 그 결과 이와 같은 평가 방법을 통해 형성 평가를 적용한 그룹 중 중위권 이상의 성적을 갖는 학습자들의 성적이 상대적으로 더 크게 향상된 것으로 분석되었다.

Purpose: To examine the changes in nurse staffing in hospitals after implementing the policy of differentiating inpatient nursing fees by staffing grades. Method: The study sample included 43 tertiary hospitals, 185 general hospitals, and 282 non-general hospitals that were operating in both 1999 and 2008. Nurse staffing grade was categorized from Grade 1 (highest) to 6 (lowest) in 1999 or Grade 7 in 2008, based on the nurse-to-bed ratio. Results: Tertiary hospitals at Grade 3 and Grade 4 accounted for 49% and 35%, respectively, in 2008, whereas 63% were Grade 6 in 1999. General hospitals at Grade 6 decreased from 87% to 48%. In non-general hospitals, little change was found in the staffing distribution, in that 92% still remained in Grade 6 or 7 in 2008. Forty tertiary hospitals (93%) and 45% of general hospitals improved their staffing grades, while only 7% of non-general hospitals did. Greater likelihood of improvement in staffing grades was found in general hospitals located in metropolitan areas or having 250 or more beds. Conclusion: Elaboration of the financial incentive system is needed to increase the policy impact on staffing improvement.

Objectives: The purpose of this study was to identify factors affecting school resilience among middle school students. Methods: The 388 survey samples were divided into high level group, middle level group and low level group in terms of the self-rated academic grades. Data were analyzed with $x^2$, ANOVA and regression analysis. Results: First, self-rated health, self-competence and school resilience were significantly different by academic grades. Second, the high and middle level group of self-rated academic grade showed the effect of self-competence(sport competence, self-worth) on school resilience. Conclusions: It was suggested to develop physical, mental and social health programs and policies were required for improvement of self-competence and the school resilience.

We separately cultured follicular oocytes collected from individual ovaries of slaughtered Korean native cows and examined both the embryonic development rate and pregnancy rate after embryo transplantation according to the meat yield and quality grades of the source beef carcass. Oocytes from meat yield grade B cows exhibited a higher fertilization rate and embryonic developmental rate to the eight-cell stage than oocytes from grade A or C animals (p<0.05), but there was no significant difference in rate of development to the blastocyst stage among meat yield grades A, Band C. The oocyte cleavage rate and development rate to the eight-cell stage from meat quality grade 3 cattle was higher than grades 1++, 1+, 1 and 2 (p<0.05). Embryos derived from grade animals displayed a development rate to the blastocyst stage of 19.4%, which was also higher than all other meat quality grades (p<0.05). Transplantation of in vitro-cultured oocytes from meat yield grade A ovaries led to a higher pregnancy rate (64.2%) than in vitro-cultured oocytes from meat yield grade B ovaries (56.5%), but there was no significant difference between the two groups in pregnancy or abortion rates. In conclusion, embryonic development rate and pregnancy rate has a close relation to meat quality grades of the source beef carcass, this results is to give information for the Korean native cows improvement of breed.

For the purpose of standardization and practicability of natural dyeing, the mordanting and dyeing properties of Acorn Shell was studied. Appropriate extraction, dyeing and mordanting condition of Acorn Shell were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of Acorn Shell solution was at 287.5nm and 294nm. The pH effect was stable in the color difference changes. The optimum temperature to extract Acorn Shell was during 1 hour in $60^{\circ}C$. The effective dyeing temperature and time of silk were $80{\sim}100^{\circ}C$, 1hour. The silk fabrics dyed with Acorn Shell appeared yellow-brown. K/S value of dyeing fabrics was increased by mordant treatment. K/S value of post-mordanting was higher than pre-mordanting. Mordanting treatment attected color change of the dyed silk. In the case of Acorn Shell light fastness of appeared more than 3-5grades by post-mordanting. Abrasion fastness of appeared more than 3-5grades. Perspiration fastness of appered more than $3{\sim}5grades$ by mordant treatment but Cu mordant treatment was $2-5{\sim}4grades$. Dry-cleaning Fastness appered more than 4 grades except Cu mordant treatment. These fastness improvement were generally effective for mordant treatment, specially Al, Sn, Cr.

The recent development of NC lathe and machining renter have enabled automatic or unmanned manufacturing system for the improvement of production rate. And if you want to introduce automatic or unmanned manufacturing system into the cutting process of cage motor rotor, the selections of effective cutting conditions, rational tool grades and tool angles are necessary. As a result, the selection of cutting conditions, tool grades and tool angles are important factors to production rate.

Two grades of Permalloy strips, Fe-45Ni(PB) and Fe-78Ni-4Mo-5Cu(PC) were fabricated by powder rolling process from elemental powder mixtures. The roll compacted green strips were sintered, homogenized, cold rolled with or without an intermediate annealing and finally heat treated to measure magnetic properties. For a given thickness reduction, rolling with an intermediate annealing was found more effective to achieve a full densification with no visible micropores and also to obtain better magnetic properties. Increasing the final rolling reduction also produced a marked improvement of the magnetic properties whereas the cooling rate during the final heat treatment has little effect in both grades. Addition of a small amount, 0.4% Mn slightly degraded the properties. As an overall, The PM strips produced via powder rolling yielded the similar soft magnetic properties to the corresponding commercial grades produced via wrought processing.
