This study was a descriptive study conducted to identify factors that had an influence on clinical competency of core basic nursing skills(CBNS) during the clinical practice in nursing students. Data were collected from 3rd and 4th grade 190 nursing students in G city using self-report questionnaire, and analyzed using descriptive statistics, the t-test, one way ANOVA, multiple regression with SPSS 23.0 program. This study found that the number of experience CBNS below 5 was 51.1%, and the number of observation CBNS over 11 was 78.4%. Clinical competency according to general characteristics, clinical practice satisfaction and the level of CBNS experience increased with male, increase age and grade, and major subject satisfaction and clinical practice satisfaction, especially, as the number of experience CBNS increased, clinical competency increased(p<0.001). But clinical competency did not differ according to the number of observation CBNS(p=0.463). The factors affecting the clinical competency of nursing students were age, grade, clinical practice satisfaction and the number of experience CBNS. Therefore, it is important to increase the opportunity to directly experience the various CBNS in clinical practice of nursing students in the nursing education curriculum, and it is necessary to find ways to actively use simulation education.

The behaviour of an earth and rock-fill dam is complicated due to reservoir water and various materials in zoned dams. Different materials with a wide range of permeability and seasonal variation of reservoir water result in the time dependent post-constructional behaviour. In aged dams it is often required to control water level to keep the dams safe. In this case information on the post-constructional dam behaviour is important. However, present geotechnical knowledge does not fully support the occasion. In this study the post-constructional behaviour of a dam is investigated using coupled finite element models for series of idealized water reservoir cases: impoundment, draw down, seasonal fluctuation with different rising and falling speeds. Numerical results were analysed in respect of geotechnical parameters such as load transfer, hydraulic fracturing potential and stress paths. It is shown that the control of water level is an important factor while operating dams.

The purposes of this study were to understand the differences of general characteristics, to compare understanding level of the organization cultures, and to develop more good management methods between outsourcing workers and regular workers in hospitals. Major results of this study were as follows: First, regular workers had higher level than outsourcing workers in major understanding on job satisfaction and organization cultures(pride of their jobs, recognition level of job performance ability, satisfaction on ordering method. etc.). Second, the results showed that the level of job performances related with effective management of the factors in job satisfaction and involvement. Third, through multiple regression analysis to understand factors on job satisfaction and involvement, we understood that regular workers were effected by vision performance of hospital and their value view-point, and outsourcing workers were influenced by recognition levels and education levels of hospital vision, Therefore, to maximize level of job satisfaction and involvement. we have interest in development of education program for outsourcing workers, and selection of adequate persons in hospital culture.

강우 발생시 유역에 집수된 물이 하천에 이르는 경로에 따른 유출은 지표유출, 지표하유출, 지하수유출로 구분된다. 정확한 수문순환 과정의 해석을 위해서는 지표 흐름뿐만 아니라 지표하 및 지하수 흐름의 해석이 중요한 실정이나 일반적으로 실무에서 사용되는 강우-유출해석 모형은 지표유출을 해석하기 위한 모형이 대부분이며, 지표하 유출과 침투량을 산정하는데 어려움이 있다. 일반적인 강우-유출해석 모형은 Horton 방법, NRCS 방법, Green-Ampt 방법에 의해 유효우량을 분리하며, 이 과정은 침투량을 직접적으로 모형화 할 수 없으므로 지표 및 지표하, 지하수 흐름을 복합적으로 해석할 수 있는 모형이 질적이나 양적으로 부족한 실정이다. 이러한 지표하 흐름과 침투량을 산정하기 위하여 FE-FLOW, PM, MS-VMS, GMS, GW-VISTAS, ARGUS 및 MODFLOW와 같은 지하수 모형을 사용하고 있다. 본 연구에서는 지표하유출 산정을 위한 침투량의 비교분석을 위해 현재 가장 범용되는 지하수 유동 모델링 프로그램인 Visual Modlfow 모형과 GMS 모형을 이용하여 침투량 산정을 위한 수치 모의를 진행하였다. 각 모형의 입력자료는 2009년 국립방재연구원에서 수행한 침투실험시설 자료를 이용하여 동일한 조건을 부여하고, 두 모형의 비교를 위해 Visual Modflow에서는 MODFLOW의 기본 해석방법인 유한차분법(FDM)을 이용하고, GMS 모형에서는 3차원 유한요소해석이 가능한 GMS-FEMWATER를 이용하였다. 두 모형의 수치모의 조건으로 2009년 국립방재연구원에서 수행한 침투실험방법과 동일하게 공극률에 따른 투수성 보도블럭의 구분과 50mm/hr, 100mm/hr, 150mm/hr, 200mm/hr의 강우강도별 선행함수조건에 따른 수치모의를 진행하였으며, 수치모의된 침투량의 적정성을 판단하기 위하여 국립방재연구원의 침투실험 결과자료와 비교분석하였다. 침투실험 자료와 각각 수치모의된 침투량을 비교분석한 결과 서로 유사한 경향을 보이고 있으나 초기 침투시 상대오차가 비교적 크게 발생하였다. 이는 수치모형의 경우 수리실험과는 다르게 모의시작과 동시에 해당 강우강도의 침투가 시작되므로 초기 유입 유출량 발생시간의 차이가 종료시간까지 누적 침투량에 미치는 것으로 판단되며, 매개변수에 많은 영향을 받는 것으로 판단된다.

This study aims to discuss the appropriateness of domestic industrial classification by analyzing whether companies are grouped into similar categories within the domestic industry classification system. The industry classification was limited to the manufacturing industry and the professional, scientific, and technical services industry, and a homogeneity test was conducted on companies belonging to these two industries. A homogeneity test was performed using companies' accounting information, selecting total accruals, the difference between sales and accounts receivable increments, and tangible assets, which are critical components of the accrual model, to represent the role of industry classification. The analysis results confirmed that the homogeneity of companies in the manufacturing industry is relatively higher than that of companies in the professional, scientific, and technical services industry. The findings of this study suggest that while the industry classification is a highly useful system that enhances the understanding of companies by enabling analysis at both the company level and the industry level to which the company belongs, it has limitations as it assumes the homogeneity of companies within an industry. Therefore, the impact of industry classification should be considered according to the research objectives.
