Objectives Excess weight and obesity are a crucial public health problem worldwide and are considered as the main cause of many chronic diseases. The present study evaluated the effects of Aronia melanocarpa extract (AMEX) supplementation on body compositions in overweight or obese people. Methods This randomized, double-blind, placebo-controlled clinical trial was carried out on 66 healthy overweight or obese peoples. The eligible subjects were divided into AMEX and placebo supplement treatment for 12 weeks. Anthropometrics, body composition (dual-energy X-ray absorptiometry), and blood analysis were performed preand post intervention. Results We observed significant reductions in the body weight and body mass index in both groups; however, the decrease was higher in the AMEX group. Body fat mass and percent body fat showed a tendency to decreases after AMEX supplementation. No clinically significant changes were observed for any safety parameter. Conclusions In conclusion, the data of this trial indicate that AMEX were not effective in reducing body compositions, but as a safe supplement, it may help weight loss in overweight or obese people.

Purpose: The role of registered nurses is expanding in scope as the healthcare paradigm shifts from acute, hospital-based care to community and population-based care. Given this paradigm shift, this study explores the legal aspects of the role of a registered nurse. Methods: We used document analysis for extracting laws and legal orders related to nursing from the entirety of Korean law. Using textualism approach, we examined the contents utilizing a framework that was developed based on the role classification of community nurses by Clark in this study. Results: A total of 119 items related to nursing were derived from 64 laws. Of these, 71.4 % can be performed by people in multiple types of occupations including nurses. As a result of analyzing required qualifications, 45.4% of 119 items required additional qualifications besides registered nurse license. Analysis of workplace and activity type demonstrated that 26.1% of the 119 items were related to medical institutions, with nurses performing mostly "Client-oriented role." More than half (68.9%) were non-medical institutions, with nurses performing mostly "Delivery-oriented role." Some, however, did not stipulate the nurse's roles clearly. Conclusion: Therefore, to match the enhanced scope and responsibilities of registered nurses and to appropriately recognize, guide, and hold these nurses accountable, laws and policy must reflect these changes. In doing so, these updated laws and policies will ultimately serve as a basis for improving the quality and safety of nursing services.

본 연구는 NCS 기반으로 개편된 미용사(피부) 검정형 자격과 과정평가형의 자격시험에 관한 선행연구의 체계적 문헌 고찰을 통해 국가기술자격 미용사(피부) 종목 과제 및 평가방법에 대해 비교·분석 하였다. 검정형 자격은 암기 위주의 이론시험과 단순 기능 반복을 통한 작업능력을 기반으로 평가가 이루어져 자격과 일이 상호 연계되지 않고 있고, 과정평가형 자격은 상대적으로 시험 집행을 시작한 기간이 짧은 상태로 시행기관에서의 자체 내부평가의 신뢰성 저하 문제가 지속적으로 나타나고 있다. 향후 현재 평가에 반영되고 있지 못하는 다양한 능력 단위를 적용하여 실기시험 평가 항목에 포함할 수 있는 상위자격의 신설 및 실기시험 평가방법 개선 등을 통해 현장과의 연계성을 제고시키고 관련 분야의 현장 적응 및 재교육 시간 단축 등의 자격제도 혁신이 필요한 것으로 사료된다.

The confined concrete stress-strain curves utilised in computational models of concrete-filled steel tubular (CFST) columns can have a significant influence on the accuracy of the predicted behaviour. A generic model is proposed for predicting the stress-strain behaviour of confined concrete in short circular, elliptical and octagonal CFST columns subjected to axial compression. The finite element (FE) analysis is carried out to simulate the concrete confining pressure in short circular, elliptical and octagonal CFST columns. The concrete confining pressure relies on the geometric and material parameters of CFST columns. The post-peak behaviour of the concrete stress-strain curve is determined using independent existing experimental results. The strength reduction factor is derived for predicting the descending part of the confined concrete behaviour. The fibre element model is developed for the analysis of circular, elliptical and octagonal CFST short columns under axial loading. The FE model and fibre element model accounting for the proposed concrete confined model is verified by comparing the computed results with experimental results. The ultimate axial strengths and complete axial load-strain curves obtained from the FE model and fibre element model agree reasonably well with experimental results. Parametric studies have been carried out to examine the effects of important parameters on the compressive behaviour of short circular, elliptical and octagonal CFST columns. The design model proposed by Liang and Fragomeni (2009) for short circular, elliptical and octagonal CFST columns is validated by comparing the predicted results with experimental results.

This study was conducted to investigate the use of medical equipment in patients receiving home care service. The subjects of this study were 88 patients cared by seven home care nursed who were registered in the Seoul Nurses Association. Data was collected from Aug. 1, 1998 to Dec. 30, 1998. The findings are as follows. 1. The sample was found to be 55.7% female : 51.7% over 65 years old. 75% with neurologic disease including CVA, brain tumor, ICH, Parkinsonism & Spinal stenosis and 78.4% living in Seoul. The Clinical experience of the home care nurses was greater than five years. 2. Medical equipment which the patients possessed were foley catheters(61.4%), L-tubes(59.1%) and tracheostomy tubes(51.1%). 3. Technical difficulties in use of medical equipment were related to home care ventilators(60.0%), L-tubes(3.8%) and tracheostomy tubes(2.2%). 4. Most of the medical equipment were obtained from the hospital where they had been admitted previously or from medical equipment companies. 5. Complications from the use of this equipment were infection through invasive techniques including wound drainage tubes(50%), and IV injections(22.2%), The complications were resolved through referral to the doctor of the hospital where they were previously admitted or through community health centers. 6. Most of the equipment was disposable, and equipment was disinfected by using various methods including boiling and soaking in antiseptic solutions. These findings suggest that consistant policy on the management of medical equipment is necessary for the safety of home care patients.

Recently, Type 2 high-pressure hydrogen storage tank is studied due to fast defect detection, easy manufacturing, and cost efficiency. Moreover, the dry winding a high-strength metal wire will make increased economic efficiency compare with the wet winding method and the carbon/glass fiber winding method. In this study, a theoretical study on the dry winding of a Type 2 high pressure hydrogen tank using a metal wire was done, and the equations of the total stress on the aligned and the staggered winding for the hoop winding were derived, and the following results were obtained by using these equations. As the diameter of the metal wire, the number of winding layers, and the outer diameter of the liner increase, the maximum stress decreases, but the difference between the maximum stress occurring in the aligned winding and the staggered winding increases. As the pressure increases, the thickness of the winding layer increases, but as the strength of the metal wire increases, the thickness of the winding layer decreases. In addition, regardless of the strength of the metal wire, the thickness of the winding layer of the staggered winding was about 13.4% thinner than that of the aligned winding.
