  • Due to frequent occurrence of abnormal weather, the need to improve the accuracy of subseasonal prediction has increased. Here we analyze the performance of weekly predictions out to 6 weeks by GloSea5 climate model. The performance in circulation field from January 1991 to December 2010 is first analyzed at each grid point using the 500-hPa geopotential height. The anomaly correlation coefficient and mean-square skill score, calculated each week against the ECWMF ERA-Interim reanalysis data, illustrate better prediction skills regionally in the tropics and over the ocean and seasonally during winter. Secondly, we evaluate the predictability of 7 major teleconnection patterns in the Northern Hemisphere: North Atlantic Oscillation (NAO), East Atlantic (EA), East Atlantic/Western Russia (EAWR), Scandinavia (SCAND), Polar/Eurasia (PE), West Pacific (WP), Pacific-North American (PNA). Skillful predictability of the patterns turns out to be approximately 1~2 weeks. During summer, the EAWR and SCAND, which exhibit a wave pattern propagating over Eurasia, show a considerably lower skill than the other 5 patterns, while in winter, the WP and PNA, occurring in the Pacific region, maintain the skill up to 2 weeks. To account for the model's bias in reproducing the teleconnection patterns, we measure the similarity between the teleconnection patterns obtained in each lead time. In January, the model's teleconnection pattern remains similar until lead time 3, while a sharp decrease of similarity can be seen from lead time 2 in July.

  • Background: This study evaluates the existing cardiopulmonary resuscitation (CPR) knowledge and skills of 1 st year dental students and also compares their CPR performance skill with those of 4 th year students. Methods: Incoming 1 st year and 4 th year dental students were surveyed about the level of their CPR knowledge before conventional CPR instruction. After we trained them for CPR performance, we tested CPR performance skill to randomly selected 10 1st year and 4 th year dental students and compared their CPR performance. Results: Overall CPR knowledge was low for both 1 st and 4 th year dental students. Especially, only 1 among 89 fourth year dental students answered the right sequence of CPR revised in 2010. Overall CPR performance was relatively low for both 1 st and 4 th year dental students. Irrespective of previous experiences of CPR education, their CPR performance was not statistically different. Conclusions: Retraining of CPR is a necessity. Information about the existing CPR knowledge for dental students will aid in establishing the goal of future CPR training and improve the current deficiency.

  • 국가직무능력표준(National competency standards, NCS)은 산업현장에서 직무를 수행하기 위해 요구되는 지식, 기술, 태도 등의 내용을 국가가 체계화한 것이다. NCS기반 현장중심 교육과정을 적용한 방사선과 재학생 3학년을 대상으로 일반촬영에 대한 방사선사 직무수행도를 평가하였다. 평가 결과, 모든 촬영방식에서 우수 및 충족 비율이 93% 이상으로 현장중심 교육과정이 재학생의 직무수행도 향상에 긍정적인 영향을 끼친 것으로 판단된다. CR 방식은 전체적으로 가장 우수한 평가를 받았으나 대상자 간 편차가 크고 영상기기조작능력이 부족한 것으로 평가되었고 Film 방식은 노출조건 설정 및 현상작업이 문제점으로 평가되었다. DR 방식은 우수한 평가를 받았으나 영상기기조작능력, 부속기자재운영능력이 부족한 것으로 평가되었다. 각 촬영에서 성취수준 이하의 평가요소를 교과목 운영에 보완한다면 재학생의 학업성취도 향상뿐만 아니라 졸업 후 임상에서 방사선사 직무수행도 향상에 도움이 되리라 판단 한다.

  • 본 연구는 인지 진단 이론을 활용하여 수학 평가 결과를 분석하고 교수 학습에 활용하는 방안을 모색하고자 하였다. $2003{\sim}2006$년에 실시된 국가수준 학업성취도 평가의 중학교 3학년 수학 검사에서 30개의 선다형 문항을 선정하여 검사지를 재구성하고 검사를 실시하였고 인지 진단 이론의 한 모형인 Fusion Model을 적용하여 평가 결과를 분석하였다. 검사 문항을 통해 학생들이 숙달한 수학적 속성을 판별하고, 학생 전체와 성취수준별로 숙달한 속성과 그 속성의 개수를 분석하였다. 그리고 학생 개개인의 수학적 강점과 약점을 분석하여 교사들에게 학생 개개인의 수학적 능력에 대한 정보를 구체적으로 알려줄 수 있었다. 이 결과는 학생들의 수학 학습에 대한 진단과 처방, 추후 학습 지도에 유용한 정보로 활용될 수 있을 것이다.

  • Purpose: The purpose of this study was to investigate the effect of the development and application of the new nurses' core skill program on the clinical skill, confidence, knowledge and performance of new nurses. Methods: This study was a nonequivalent control group post-test design on 46 new nurses with 3 to 6 months work experience in a general hospital. Data were collected from August 2015 to August 2016. A training program of core fundamental nursing skills was applied on 23 new nurses from 2016 in the experiment group, and an existing training method was applied on 23 new nurses from 2015 in the comparison group. The collected data were analyzed using SPSS/WIN 23.0. Results: The experimental group ($89{\pm}4.29$) showed higher score in practical skill assessment compared to the control group ($85.09{\pm}3.99$) and showed a statistically significant difference (p<001). Conclusion: A training program of core fundamental nursing skills for new nurses proved effective in improving practical skills. Further research on the development of a systemic training program that can improve clinical nursing knowledge and work ability for new nurses according to the extended enforcement of a Nursing Care Integrated Service ward is needed.

  • Purpose: Implicit motor learning is the capacity to acquire skill through physical practice without conscious awareness of what elements of performance improved. This study investigated whether subacute stroke patients can implicitly learn a perceptual-motor task. Methods: We recruited 12 patients with subacute stroke and 12 age-matched controls. All participants performed a perceptual-motor task that involved pressing a button corresponding with colored circles (blue, green, yellow, red) on a computer screen. The task consists of 7 blocks composed of 10 repetitions for a repeating 12-element sequence (total 120 responses). Results: Both groups demonstrated significant improvement in acquisition performance. Reaction times deceased in both groups at similar rate within the sequential block trials (2-5 blocks), and reaction times increased at a similar rate when the task paradigm was transferred from the sequential block trial to the random block trial (5-6-7 blocks). Conclusion: The results of this study suggest that patients with sub-actue stroke can implicitly learn a perceptual motor skill. Although explicit instructions should be used to focus the learner's attention rather than provide information about the task, the application of implicit motor learning strategies in the rehabilitation setting may be beneficial.

  • In the accounting information system implementation, the users should consider the benefits and advantages of the system. This paper examines the effect of the Enterprise Resources Planning based (ERP-based) accounting information system implementation on user impact and organizational impact. The population in this study is companies listed on the Indonesian Stock Exchange, especially companies based in Riau, Indonesia. These companies currently use the ERP-based accounting information system. Research samples are employees who use the ERP-based accounting information system. For data analysis, we use structural equation modeling (SEM). Based on data analysis, high-quality information system implementation generate high-quality information that can give satisfaction to the user. Moreover, the information system is related to user skill, satisfaction, and knowledge sharing which improve personal skills; enhanced personal skill contributes to organizational performance. On the other hand, there is no effect of training on personal skills and there is no effect of information quality on perceived usefulness. This research gives implication to the organization for implementing a high-quality ERP-based accounting information system that positively impacts organizational performance. Future research is expected to examine information system implementation in different research objects and conditions.

  • The purpose of this study is to optimally allocate the human resources to tasks while minimizing the total daily human resource costs and smoothing the human resource usage. The human resource allocation problem (hRAP) under consideration contains two kinds of special constraints, i.e. operational precedence and skill constraints in addition to the ordinary constraints. To deal with the multiple objectives and the special constraints, first we designed this hRAP as a network problem and then proposed a Pareto multistage decisionbased genetic algorithm (P-mdGA). During the evolutionary process of P-mdGA, a Pareto evaluation procedure called generalized Pareto-based scale-independent fitness function approach is used to evaluate the solutions. Additionally, in order to improve the performance of P-mdGA, we use fuzzy logic controller for fine-tuning of genetic parameters. Finally, in order to demonstrate the applicability and to evaluate the performance of the proposed approach, P-mdGA is applied to solve a case study in a hotel, where the managers usually need helpful automatic support for effectively allocating hotel staff to hotel tasks.
