Purpose: This study was done to examine the effect of direct practice of newborn health assessment on nursing student's clinical competence and self-efficacy and to propose effective strategies for clinical education on newborn care. Methods: Design was a nonequivalent control group quasi-experimental study. The direct practice program was composed of a lecture, demonstration, drill and feedback using a manikin, and repeated direct practice regarding newborn health assessment. Participants were 65 student nurses taking the pediatric nursing practicum in the nursery room at M hospital. The experimental group (n=33) participated in the direct practice program for newborn health assessment and the control group (n=32) received the traditional practice method. Nursing clinical competence was assessed by two nurse investigators and structured questionnaires were used to measure self-efficacy. Results: The experimental group's clinical competence was significantly higher than that of the control group (t=-4.82, p=.000). However no significant difference was found between the two groups for self-efficacy (t=1.264, p=.211). Conclusion: These findings indicate that the direct practice program is effective in improving nursing student's clinical competence, but it was not effective in increasing self-efficacy. Direct practice in various clinical education settings is recommended and longitudinal effects be evaluated.

본 연구는 충청남도 직영기업을 대상으로 지방공기업 경영평가의 수용성을 분석하였다. 이를 위해 지방공기업 경영평가와 관련하여 5개 측면으로 영역을 구성하고 지방공기업 경영평가의 수용성과의 영향여부를 분석하였다. 직영기업은 조직 구조상 다른 공기업들과 다른 형태를 지니고 있어서 경영평가가 효율적으로 운영되기 위해서는 보다 차별화된 전략이 필요시 된다. 상하수도의 경우 지방자치단체 조직으로 경영평가 결과의 환류가 어려운 특징이 있어 관리자의 관심과 노력이 필수적으로 요구된다. 또한, 경영평가를 통한 직영기업의 성과를 높이기 위해서는 담당자의 전문성이 필요시 되는 만큼 이를 위한 정책적 운영방안이 필요시 된다. 무엇보다 경영평가 결과에 대한 인센티브가 다른 공기업처럼 의도한 효과를 내기 어려운 구조에 있다. 따라서 평가결과에 대한 보상시스템에 대한 차별화가 필요할 것이다. 본 연구의 한계가 있으나 상대적으로 특성이 다른 상하수도 관계자에 대한 의식조사가 이루어진 만큼 향후 경영평가제도의 운영방향을 모색하는데 기여할 수 있다는 것에 의의를 지닌다.

Purpose: The purpose of this study was to present evidence for quality management based on analysis of patient transportation and response intervals among emergency medical squads. Methods: The chi-square test was used to determine whether mental status and patient assessment affected direct medical control and hospital destination. One way analysis of variance was used to compare response intervals depending on mental status and patient assessment using data drawn from 1172 prehospital care reports. Results: There was a statistically significant relationship between mental status and direct medical control (p<.001); there was a statistically significant relationship between patient assessment and hospital destination (p=.011). However, there was no statistically significant relationship between mental status and hospital destination. The interval from arrival at the patient's side to departure from the scene showed a statistically significant difference (p<.001, p<.001), however, it took the longest time (16.8 minutes) in unresponsive patients. It showed a statistically significant difference (p<.001) in the interval from arrival at patient's side to departure from the scene depending on patient assessment; however, it took the longest time (9.6 minutes) in emergency patients. Conclusion: There was call for direct medical control based on patient assessment; however, patient transportation and response intervals were not appropriate.

매설배관의 부식위험성을 최소화하고 음극방식의 효율극대화를 위해 다양한 비굴착 간접검사기법들이 수십년 전부터 이용되고 있으며, 미국에서는 굴착을 통한 매설배관 외면부식 직접평가법을 CFR 코드에서 규정하고 있다. 국내의 경우에는 도시가스사업법 관련 4개의 기준(KGS Code)에서 배관의 손상여부를 측정할 수 있는 장비를 이용하여 배관의 상태를 점검, 측정하고 이상부위에 대하여 누출검사를 한 경우 매설배관의 기밀시험을 한 것으로 보고 있을 뿐 배관외면부식 직접평가에 대한 규정은 없다. 본 논문에서는 미국, 영국 등 국외의 매설배관 건전성 관리 기준 및 방법을 조사하고, 국내의 매설배관 방식관리 실태 및 피복손상탐지 장치 이용실태 등을 조사한 후 국내 실정에 맞는 매설배관 외면부식 직접평가법을 제시하였다. 본 논문에서 제시한 매설배관 외면부식 직접 평가법은 국내에서 중압배관의 정밀안전진단 제도를 도입하는데 기초 자료로 활용되었다.

The technology of direct-seeding in rice cultivation is an innovation mainly induced by factors in market economy and is rapidly diffused among individual farmhouses. Because the effect of technology can be affected by many factors under various farming circumstances, the impact and stability of the direct-seeding technology compared with transplanting was analyzed under various topographical regions. Yield in direct-seeding was higher in plains, although the farm size producing higher yield was quite different depending on the topographical regions. In the direct-seeding cultivation of rice, man-labor hours was reduced by about 38 percent and the reduction rate showed little difference among topographical regions. Fertilizer was used about 11 percent more but the increase rate varied from 3 to 17 percent depending on regions with higher rates in plains. Application of agricultural chemicals was also increased about 9 percent in direct-seeding, but the increase rate was as high as 12 percent in suburbs. More fertilizer and agricultural chemicals were used in direct-seeding cultivation by farmhouses implementing both direct-seeding and transplanting than by those implementing direct-seeding only. Use of more fertilizers and agricultural chemicals in direct-seeding in all regions may indicate its technical instability. Major problems causing the technical instability of direct-seeding cultivation should be solved by comprehensive research considering various farming circumstances such as topographical features rather than just a top-down style research and extension.

The accelerated corrosion by Flow Accelerated Corrosion (FAC) has caused unexpected rupture of piping, hindering the safety of nuclear power plants (NPPs) and sometimes causing personal injury. For the safety, it may be necessary to select some pipes in terms of condition monitoring and to measure the change in thickness of pipes in real time. Direct current potential drop (DCPD) method has advantages in on-line monitoring of pipe wall thinning. However, it has a disadvantage in that it is difficult to quantify thinning due to various thinning shapes and thus there is a limitation in application. The machine learning approach has advantages in that it can be easily applied because the machine can learn the signals of various thinning shapes and can identify the thinning using these. In this paper, finite element analysis (FEA) was performed by applying direct current to a carbon steel pipe and measuring the potential drop. The fundamental machine learning was carried out and the piping thinning model was developed. In this process, the features of DCPD to thinning were proposed.

A life cycle impact assessment was applied in an industrial waste incineration plant to evaluate the direct and indirect environmental impacts based on toxicity and non-toxicity categories. The detailed life cycle inventory of material and energy inputs and emission outputs was compiled based on the realistic data collected from a local industrial waste incineration plant, and the Korean life cycle inventory and ecoinvent database. The functional unit was the treatment of 1 tonne of industrial waste by incineration and the system boundary included the incineration plant and landfilling of ash. The result on the variation of the impact by the unit processes showed that the direct impact was decreased by 79.3, 71.6, and 90.1% for the processes in a semi dry reactor, bag filter, and wet scrubber, respectively. Considering the final impact produced from stack, the toxicity categories comprised 91.7% of the total impact. Among the toxicity impact categories, the impact in the eco-toxicity category was most significant. A separate estimation of the impact due to direct and indirect emissions showed that the direct impact was 97.7% of the total impact. The steam recovered from the waste heat of the incineration plant resulted in a negative environmental burden.

This work evaluates the performance of a number of seismic assessment procedures when applied to a case study reinforced concrete (RC) wall building. The performance of each procedure is evaluated through its ability to accurately predict deformation demands, specifically, roof displacement, inter-storey drift ratio and wall curvatures are considered as the key engineering demand parameters. The different procedures include Direct Displacement-Based Assessment, nonlinear static analysis and nonlinear dynamic analysis. For the latter two approaches both lumped and distributed plasticity modelling are examined. To thoroughly test the different approaches the case study building is considered in different configurations to include the effects of unequal length walls and plan asymmetry. Recommendations are made as to which methods are suited to different scenarios, in particular focusing on the balance that needs to be made between accurate prediction of engineering demand parameters and the time and expertise required to undertake the different procedures. All methods are shown to have certain merits, but at the same time a number of the procedures are shown to have areas requiring further development. This work also highlights a number of key aspects related to the seismic response of RC wall buildings that may significantly impact the results of an assessment. These include the influence of higher-mode effects and variations in spectral shape with ductility demands.

This study analyzed the characteristics of diverse information adoption pathways per pathway of information composition category including 'information perception', 'information assessment', and 'information adoption' and examined information adoption characteristics per pattern. In addition, differences among agricultural researchers and farmers per information adoption stage were analyzed. According to these analyses, as for farmers' information adoption pathways, while the formal extension type and the situational reaction diffusion type used the direct pathway of 'information perception ${\rightarrow}$ information adoption,'the agriculturist connection type and the systematic approach type did not use the direct pathway of 'information perception ${\rightarrow}$ information adoption' but, instead, adopted information by moving from the 'information perception ${\rightarrow}$ information assessment' pathway to the 'information assessment ${\rightarrow}$ information adoption' pathway, with information assessment as the intermediation. In the case of farmers, information adoption was the highest in comparison with information assessment and information perception in all patterns whereas, in the case of agricultural researchers, the results were exactly opposite those of farmers. By suggesting an information adoption pathway appropriate to each pattern, this study sought to enhance information adoption.
