CCPM 기법에서는 프로젝트 버퍼의 크기를 결정하기 위해 일반적으로 자르고 붙이는 방법과 루트-제곱하는 방법을 사용한다. 하지만 이러한 방법은 프로젝트의 특성을 고려하지 않고 고정된 공식을 통해서만 계산하기 때문에 버퍼의 크기가 너무 커지거나 작아지는 경우가 자주 발생했다. 본 논문에서는 위의 문제점을 해결하기 위해 이전 작업의 결과를 통계 분석하여 각 작업자에 대한 각 임무의 종류에 따른 작업의 특징을 파악하고 이를 CCPM 기법에 활용하여 해당 특징을 기준으로 버퍼 크기를 산정하는 새 방법을 제시하였다. 몬테카를로 시뮬레이션 환경에서 임무의 수, 임무의 어려운 정도 등의 요소를 반영하여 나온 결과를 비교분석 해서 본 논문에서 제안한 방법이 기존의 방법에 비해 임무 수와 상관없이 안정된 완공확률을 유지할 수 있음을 확인하였다. 또한 특정 작업자가 일찍 완공할 수 있는 임무들의 경우 제안한 방법은 기존 방법보다 버퍼의 크기를 더 단축하는 것을 확인하였다.

Aims: This study aimed to analyze the tasks of Korean Medicine (KM) nurses. Methods: The definition and job description of KM nurses were developed through a "developing a curriculum" (DACUM) workshop. DACUM committee consisted of nine nurses from eleven Korean medicine hospitals, two DACUM facilitators and four DACUM coordinators. Twenty five nurses from nine Korean medicine hospitals validated job description established through the workshop. 235 KM nurses from 9 traditional Korean medicine hospitals participated in evaluating frequency, importance and difficulty of the duties and tasks. Questionnaires were sent to those nurses and 225 responses were included for final analysis due to missing data. The data were analyzed using descriptive statistics. Results: The jobs of a KM nurse were analyzed into 11 duties and 86 tasks on the DACUM chart. The 11 duties were KM nursing assessment, KM nursing intervention, fundamental nursing intervention, KM therapy management, support for KM therapy, KM nursing education, nursing administration, material management, environment management, professional development, and collaborative role between Korean medicine and Western medicine. Conclusion: We identified various roles of KM nurses and developed a DACUM chart based on their duties and tasks. Phased education programs for KM nurses should be developed by considering frequency, importance and difficulty. In addition, it is necessary to promote unique KM nursing interventions for expanding the roles of KM nurses in the future.

Objective: The purpose of this study was to determine the physical load by identifying harmfully working postures and to develop recommendations for improving the existing situation with nurses in ICU, thereby to provide the basis for development of work-related musculoskeletal preventive program. Method: Various types of tasks were recorded with a video camera to chart and analyze different postures by OWAS(Ovako Working Posture Analysing System). Collected data showed that poor postures were adopted, not only for lifting or repositoning a patient, but also for other tasks. Data Analysis: The performed activities were then divided into Nursing Intervention Classification. Altogether 128 postures were selected for analysis. Then they were classified into different OAC (OWAS Action Categories). From all the observation, unhealthy postures, for which corrective measures had to be considered immediately (i.e., 75% classified as OACII+III+IV) were found. Collected data were analyzed in terms of percentage, 2-tail Mann-Whitney U test. Result: Poor postures mainly occur during 'positioning the patient' and 'airway suctioning' in NIC. No difference was found (p=0.060) between the percentage of harmful posture adopted during the patient handling tasks and non-patient handling tasks. Conclusion: This study shows, that in the nursing profession with ICU not only occur during patient handling, but also during other activities. The OWAS method was useful in determining the physical load by locating potential activities due to harmfully working postures, providing a detailed description with analysis, and suggesting successful means to reduce postural load.

This paper investigated the teaching and teaming of contents-related graphing in Korean secondary textbooks and suggested the improved methods of graph instruction through this analysis. reification-the case of function, In Harel, G., Dubinsky(Eds.), The Concept of Function : Aspects of Epistemology and Pedagogy Textbooks are analyzed from the viewpoint of the proportion of graphing contents, their sequencing, the proportion of each domain in graphing activities (interpretation vs. construction, quantitative vs. qualitative aspect, local vs. global aspect) and tasks (prediction, translation, scaling), and the difference in the graphing contents between the sixth and the seventh curriculum. This analysis demonstrates that graphing contents are increasing in textbooks, therefore the high school textbooks appear in almost every content area. The graphing activities concentrate on the construction, the quantitative aspects, and the local aspects, and are gradually focusing on the interpretation and global aspects of high school textbooks. Furthermore, most of graphing tasks favor translation. In contrast, the current seventh curriculum includes a balance of interpretation and construction activities and has more global aspects than the sixth curriculum based textbooks; however, the qualitative approach still rarely appears. For the graphing tasks, translation is still prevalent, but the importances of prediction tasks based on graph have increased in comparison with the sixth curriculum textbooks. Further, the seventh curriculum based textbooks are designed to stimulate more dynamic graphing instruction by introducing new tools such as graphing calculators and computer software. We suggest that the qualitative and global aspects should be emphasized in early graph instruction, a variety of graph activities in realistic contexts should be performed, and educational technology such as graphing calculator and computer can be efficient to implement these ideas.

Purpose: This study aims to systematically review the dual-task evaluation applied to the screening of mild cognitive impairment. It also aims to present various evaluation items and results analysis methods for dual tasks applied to patients with mild cognitive impairment. Methods: We conducted a systematic search of published studies in PubMed databases and KISS from January 2000 to August 2020 using the main keywords such as "Dual task," "Mild Cognitive impairment," "Elderly," and "Screening." We selected a total of 10 studies for the analysis from 1314 searched articles. Results: We analyzed the qualitative level of 10 studies that were nonrandomized two-group studies with evidence level II (100.0%). These results suggest that the evidence level of the studies was high. We analyzed 10 studies and identified 12 motor tasks and 19 cognitive tasks. Walking was the most commonly used evaluation motor task and counting backward by ones and naming animals were the most commonly used evaluation cognitive tasks. Moreover, the velocity speed was the most used result analysis method. The results indicate that there were significant differences in dual-task performance between patients with normal and mild cognitive impairment. Conclusion: The results of this study can be used as a basis for the selection of dual-task evaluation items and methods of analyzing the results for screening mild cognitive impairment. Furthermore, they are expected to be used for research on the development of dual-task evaluation tools. It is necessary to compare and analyze the usage trends of dual-task evaluation by cultural differences in future studies.
