Purpose: To develop staffing levels for nursing personnel (registered nurses and nursing assistants) to provide inpatients with integrated nursing care that includes, in addition to professional nursing care, personal care previously provided by patients' families or private caregivers. Methods: A time & motion study was conducted to observe nursing care activities and the time spent by nursing personnel, families, and private caregivers in 10 medical-surgical units. The Korean Patient Classification System-1 (KPCS-1) was used for the nurse manager survey conducted to measure staffing levels and patient needs for nursing care. Results: Current nurse to patient ratios from the time-motion study and the survey study were 1:10 and 1:11, respectively. Time spent in direct patient care by nursing personnel and family/private caregivers was 51 and 130 minutes per day, respectively. Direct nursing care hours correlated with KPCS-1 scores. Nursing personnel to patient ratio required to provide integrated inpatient care ranged from 1:3.9 to 1:6.1 in tertiary hospitals and from 1:4.4 to 1:6.0 in general hospitals. The functional nursing care delivery system had been implemented in 38.5% of the nursing units. Conclusion: Findings indicate that appropriate nurse staffing and efficient nursing care delivery systems are required to provide integrated inpatient nursing care.

Purpose: This study was conducted to examine activities of daily living (ADL) of older adults admitted to Korean long-term care hospitals (LTCHs), and to explore the patient and organizational factors that have an impact on the ADL of this population. Methods: A secondary analysis of the Korean minimum data set (K-MDS) of patients (N=14,369) and of the profiles of LTCHs (N=358) from the Health Insurance Review and Assessment Service was done between January and July 2008. The outcome variable was ADL score 6 months after baseline assessment. Multi-level linear regression was employed to explore the patient and organizational factors that affected ADL scores. Results: Of the patients, 45.4% had a baseline ADL score of between 31 and 40, with a score of 40 indicating that the patient was entirely dependent for all items. None of the organizational characteristics were significantly associated with effects on the ADLs of older adults who had been in a LTHC for at least 6 months. However, patient characteristics, such as age, baseline ADL, frequency of physical therapy, urinary incontinence, fecal incontinence, pressure ulcers, and having a tube or catheter, were significantly associated with ADL 6 months after baseline. Conclusion: In order to maintain and improve the ADL of older adults in LTCHs, we should develop strategies to prevent urinary and fecal incontinence, pressure ulcers, unnecessary tubes or catheters, providing adequate physical therapy. Additional studies should include more detailed information regarding nursing staff, including RN hours for direct care, education level and turnover.

Background: The National Breast Cancer Audit Database of the Society of Breast Surgeons of Australia and New Zealand is used by surgeons to monitor treatment quality and for research. About 60% of early invasive female breast cancers in Australia are recorded. The objectives of this study are: (1) to investigate associations of socio-demographic, health-system and clinical characteristics with treatment of invasive female breast cancer by mastectomy compared with breast conserving surgery; and (2) to consider service delivery implications. Materials and Methods: Bi-variable and multivariable analyses of associations of characteristics with surgery type for cancers diagnosed in 1998-2010. Results: Of 30,299 invasive cases analysed, 11,729 (39%) were treated by mastectomy as opposed to breast conserving surgery. This proportion did not vary by diagnostic year (p>0.200). With major city residence as the reference category, the relative rate (95% confidence limits) of mastectomy was 1.03 (0.99, 1.07) for women from inner regional areas and 1.05 (1.01, 1.10) for those from more remote areas. Low annual surgeon case load (${\leq}10$) was predictive of mastectomy, with a relative rate of 1.08 (1.03, 1.14) when compared with higher case loads. Tumour size was also predictive, with a relative rate of 1.05 (1.01, 1.10) for large cancers (40+ mm) compared with smaller cancers (<30 mm). These associations were confirmed in multiple logistic regression analysis. Conclusions: Results confirm previous studies showing higher mastectomy rates for residents of more remote areas, those treated by surgeons with low case loads, and those with large cancers. Reasons require further study, including possible effects of surgeon and woman's choice and access to radiotherapy services.

In this study, the traditional takju was manufactured using the finger root, which was recognized as a health functional ingredient, and analyzed the physicochemical and sensory quality characteristics according to the period of fermentation. The pH was significantly low(p<0.05) in all samples until the second day of fermentation, and the pH tended to increase again from the third day of fermentation. The pH value was decreased as the amount of finger root was decreased(p<0.05). The acidity of takju was significantly lower at 0.17~0.21 immediately after fermentation(p<0.05). The acidity of FR0 showed significantly the highest value(p<0.05). The sugar content of takju was significantly increased in all the samples until the 2nd day of fermentation(p<0.05). On the 7th day, it showed the lowest value at $11.01{\sim}12.63^{\circ}Brix$. The sugar content of FR0 was significantly lowest value(p<0.05). The alcohol content of takju was significantly increased as the fermentation proceeded, and the highest value was 11.90~13.50% at 7 days(p<0.05). The alcohol content of RF0 was significantly higher than other samples(p<0.05). As a result of organic acid analysis of finger root takju fermented for 7 days, citric acid(3.35%) showed the highest content of FR3(p<0.05). The content of fructose increased with increasing finger root amount (p<0.05). As a result of sensory evaluation of finger root takju, FR1 and FR2 samples tended to be lower in score than FR0, and FR3 showed the highest score. The overall acceptance value of FR0 was 7.5 and FR3 was 7.57.

Background: Kawasaki disease (KD) is an acute febrile, systemic vasculitis as a leading cause of acquired heart disease in children. Intravenous immunoglobulin G (IVIG) and aspirin are the standard initial therapy in the treatment of acute KD. The purpose of this study was to investigate drug utilization in children with KD, and to compare "IVIG + high-dose aspirin" and "IVIG + moderate-dose aspirin" in preventing cardiac complications. Methods: We analyzed pediatric patient sample data compiled by the Health Insurance Review & Assessment Service from 2010 to 2015. We identified patients with KD using the KCD-6 code of M30.3. We excluded patients in chronic phase or ${\geq}1$0 years. We also excluded patients who were diagnosed KD in November or December. Drug utilization pattern were assessed in acute KD patients and 30-day and 60-day cardiac complications were investigated between "IVIG + high-dose aspirin" group and "IVIG + moderate-dose aspirin" group. Results: In acute phase, IVIG was administered to 95.8% patients, and 57.1% patients were prescribed moderate-dose aspirin and 25% patients were with high-dose aspirin. Steroid use was rapidly increased from 4.0% in 2010 to 11.3% in 2015. Both 30-day and 60-day cardiac complications occurred less in "IVIG + high-dose aspirin" group compared to "IVIG + moderate-dose aspirin" group, but not statistically significant (0.9% vs 1.8%, p=0.252 for 30-day complication rate; 1.5% vs 2.7%. p=0.073 for 60-day complication rate). Conclusion: We were not able to demonstrate which aspirin therapy is superior for preventing cardiac complications in acute KD patients and further research is warranted.

본 연구에서는 정부정책이 효과가 있었는지 파악하기 위하여 과거 10년간의 산업재해 데이터를 살펴보았다. 이들 데이터로부터 중요한 두 개 또는 세 개의 변수간의 관계를 EDA 방법으로 살펴보았다. 근로자수(사업장규모)와 생존확률 간의 관계를 살펴본 결과 근로자수가 많을수록 시간이 지남에 따라 생존확률이 더욱 더 떨어짐(산업재해가 더 많이 일어남)을 알 수 있다. Cox의 비례위험모형을 적용해본 결과 사업장에서 발생한 총산업재해수가 많을수록 해당 사업장에서 산업재해가 발생할 위험성(hazard)이 높아지고, 근로자수가 적을수록 산업재해가 발생할 위험성이 높으며, 업종별로는 농업, 어업 및 임업이 건설업에 비해 산업재해를 당할 위험성이 더 크다. 공단, 민간 및 고용노동부의 역할은 고용노동부만 효과가 있고, 나머지 두 조직은 효과가 없는 것으로 나온다. recurrent event data를 Cox의 비례위험모델로 분석해본 결과 비슷한 결과가 나온다.
