This study is to develop cooperative learning aids for Clothing and Textiles classes, and to develop methods and tools for performance assessment. We have surveyed 127 students with‘class evaluation’questionnaire after teaching 9 classes through developed materials. As a result, we found that students preferred to cooperative learning and they tended to do their best in their assigned role in the cooperative learning. Meanwhile, we also found that they understood the assignment of performance assessment well and they felt lack of time to handle given tasks. It shows that we need to be flexible when applying a teaching method in a way that teachers give student more options to choose their duty and time span. Although a few students create a problem and delay their duty as disturbing cooperation in a group we anticipate that the developed teaching aids and performance assessment will be a great help to improve Home Economics classes. In closing, we believe that we can be open-minded Home Economics educators that continue to work on improving classes through developing diverse teaching aids and performance assessment.

Recently, there are growing interests in building LCCO₂ Assessment to reduce carbon emissions. However, existing methods of assessment system include inefficiency in the process of CO₂ calculation requiring considerable data input. Therefore, the purpose of this study is to develop an efficient building assessment system appropriate to material production in construction stage. To that end, quantity input technology was limited to data mapping. Also quantity calculation based on work breakdown structure and item codes consisted of hierarchical structure that is based on facet classification were analyzed. As a result, connectivity links of quantity calculation and CO₂ functional units through item codes for data mapping, and assessment system including calculation and database parts were developed.

Appropriate strategies are needed to ensure long-term preservation of various types of electronic records. For proper preservation of electronic records, it is necessary of decision-making processes for risk assessment, notification and implementation of conservation measures. To do this, the task of assessing various risk factors that impede the long-term preservation and utilization of electronic records should be done first. In this study, since electronic records are mostly stored in file form, risk assessment for electronic records of file type is performed. The risk factors required for the risk assessment of the file format are derived, and the algorithms are developed to devise a calculation method of the weighting factor and the risk factor index for evaluating the risk based on the proposed risk factors. In addition, the proposed methods are applied to the file formats used in Korea and risk assessment is performed and the results are analyzed.

In this paper, we present the FlappyBird Competition System (FCS) implementation, a competition-based automated assessment system used in an entry-level artificial intelligence (AI) course at a university. The proposed system provides an evaluation method suitable for AI courses while taking advantage of automated assessment methods. Students are to design a neural network structure, train the weights, and tune hyperparameters using the given reinforcement learning code to improve the overall performance of game AI. Students participate using the resulting trained model during the competition, and the system automatically calculates the final score based on the ranking. The user evaluation conducted after the semester ends shows that our competition-based automated assessment system promotes active participation and inspires students to be interested and motivated to learn AI. Using FCS, the instructor significantly reduces the amount of time required for assessment.

하천을 설계할 때 적절한 호안공법을 선정해야 하지만 이에 대한 가이드라인이 없는 실정이다. 따라서 하천설계시 채택한 호안공법들의 적합성 여부를 판단함으로서 예산의 낭비를 막을 필요가 있다. 본 연구에서는 하천설계시 채택한 호안공법들이 적합한지를 평가하는 방법을 개발하고, 이를 8개 하천에 적용함으로서 개발된 방법의 타당성을 검토하였다. 평가방법은 계층화분석법(AHP)을 사용하였으며 각 하천에 적용된 호안 공법의 적합도(SI)를 분석하여 평가하는 방법을 사용하였다. 최적 호안공법이 선정되기 위해서는 설계대상지점의 모든 환경변수가 고려되어야 할 것이다. 따라서 설계호안을 평가하기 위해서도 대상지점이 가지고 있는 모든 변수가 포함되어야한다. 호안평가항목은 호안의 수리적 안정성, 환경생태성, 경제성, 어메니티의 4가지 항목을 사용하였으며 각 항목은 4~5개의 소항목을 포함하며 각 소항목은 대상지점의 조사결과를 반영한 자료이다. 평가방법은 8개 하천을 대상으로 적용되어 평가되었으며 설계된 호안의 SI를 판정하였다. 본 연구의 결과는 특히 자연친화적인 호안공법을 평가하는 데 적합할 것으로 생각되며 부적절하게 설계된 호안은 적절한 공법을 선정하는데 도움을 줄 수 있을 것이다.

현대사회는 대도시의 구조물 설계 시 협소한 공간제약을 극복하기 위해 옥상 및 지하공간을 활용하고 있으며, 이에 따라 바닥재의 시공도 증가하고 있다. 바닥재의 미끄럼저항성능은 보행자 및 운전자의 안전성 및 쾌적성 관점에서 대단히 중요한 성능임에도 불구하고, 바닥재의 미끄럼저항성능에 대한 뚜렷한 기준이 없어 개선이 되고 있지 않은 실정이다. 본 논문에서는 국토해양부의 도로안전시설 설치 및 관리지침과 서울시의 서울형 보도포장 미끄럼 저항 기준에 기초하여 미끄럼저항성능의 평가방안을 제시하였다. 세 가지의 우레탄 바닥재 시공법을 선정하여 실험적인 연구를 통해 각 바닥재의 미끄럼저항성능을 분석하고, 제시된 평가 방안에 따라 평가하였으며, VE분석을 통해 세 가지 바닥재 시공법의 성능을 종합적으로 평가함으로써 미끄럼저항성능이 우수한 바닥재가 시공될 수 있도록 독려하였다. 본 논문에서 제시된 평가방법에 따른 VE분석 결과, 미끄럼저항성능이 최대 4배 이상 향상되었던 파티클재료를 첨가한 공법이 83.86의 성능지수를 보임으로써 기타 비교안에 비해 가장 우수한 성능을 나타내었다.

우리나라 모든 산업에서 근골격계질환은 작업자들의 안전에 큰 영향을 미치고 있으며, 산림작업은 산업안전보건법에 따라 근골격계 부담작업으로 분류된다. 특히 벌도 및 가지제거작업은 주로 인력작업으로 실시되고 있으며, 작업원의 안정성 확보를 위해 작업자세에 대한 평가가 필요하다. 따라서 본 연구는 체인톱을 이용한 벌도 및 가지제거작업의 작업자를 대상으로 세가지 인간공학적 분석 도구(OWAS, RULA, REBA)를 이용하여 위험도를 평가하고, 평가기법별 작업자세에 대한 영향인자를 분석하였다. 벌도와 가지제거작업자세의 위험도는 RULA, OWAS, REBA 순으로 높게 평가되었으며, 대부분 2-3단계로 작업자세의 즉각 변경조치는 요구되지 않았다. 하지만 벌도작업에서 허리와 다리를 굽힌자세와 가지제거작업에서 벌도목 위에서 작업하는 자세는 위험도가 매우 높게 분석되었다. 또한 벌도작업의 경우 산지경사, 가지제거작업의 경우는 지상에서부터 벌도목 높이가 작업위험도 평가에 영향이 높은 것으로 분석되었다. 따라서 산림작업에 있어서 작업자의 안전성을 확보하기 위해 작업부하가 낮은 자세(벌도작업: 쪼그리는 자세, 가지제거작업: 허리와 다리가 곧은 자세)로 작업하는 것이 바람직한 것으로 사료된다.

Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using $x^2$-test (Fisher's exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.
