본 연구는 간호학 전공수업에 적용한 블렌디드 러닝이 간호학과 학생들의 학업성취도와 자기주도적 학습 능력에 미치는 효과를 규명하기 위한 비동등성 대조군 전후설계 실험연구이다. 연구대상은 J도에 소재한 4년제 간호학과 3학년 중 실험군 75명, 대조군 70명으로 총 145명이었다. 총 15주 동안 블렌디드 러닝을 실시하였으며 실시 전과 후에 자기주도적 학습능력을 측정하였고 중간고사, 기말고사를 통해 학업성취도를 측정하였다. 측정된 결과는 $x^2$-test와 Fisher's exact test, t-test, paired t-test로 분석하였다. 연구결과 블렌디드 러닝은 학습계획, 학습실행, 학습평가로 구성된 자기주도적 학습능력을 증진시켰고 기말고사에서 학습자의 학업성취도를 높여주었다. 그러므로 본 연구는 학습방법으로의 블렌디드 러닝이 학생들의 간호학 전공수업에 효과적임을 파악한 점에서 연구의 의의를 지니며, 향후 간호관련 전공학문 분야의 효과적인 교수법으로 확대적용 할 수 있을 것으로 기대한다.

Over the past few years, training professionals have become more pragmatic in their approach to technology-based media by using it to augment traditional forms of training delivery, such as classroom instruction and text-based materials. This trend has led to the rise of the term blended learning. Blended learning, an environment of e-learning, is a powerful learning solution created through a mixture of face-to-face and online learning delivered through a mix of media and superior learning experiences. In this article we design and implement an e-learning environment for blended learning. The environment focused on following factors: learning activity and participation of learners, and real time feedback of instructor.

Background: With the emergent transition of online learning during the COVID-19 pandemic, the need for online/offline blended learning that can effectively be utilized in a team-based learning (TBL) course has emerged. Methods: We used the online metaverse platforms, Gather and Zoom, along with face-to-face teaching methods in a team-based Introductory Pharmacy Practice Experience (IPPE) course and examined students' learning satisfaction and achievement, as well as their preferences to the learning platforms. A survey questionnaire was distributed to the students after the IPPE course completion. All data were analyzed using Excel and SPSS. Results: Students had high levels of course satisfaction (4.61±0.57 out of 5) and achievement of course learning objectives (4.49±0.70 out of 5), and these were positively correlated with self-directed learning ability. While students believed that the face-to-face platform was the most effective method for many of the class activities, they responded that Gather was the most effective platform for team presentations. The majority of students (64.3%) indicated that blended learning was the most preferred method for a TBL course. Conclusion: Students in a blended TBL IPPE course had high satisfaction and achievements with the use of various online/offline platforms, and indicated that blended learning was the most preferred learning method. In the post-COVID-19 era, it is important to utilize the blended learning approach in a TBL setting that effectively applies online/offline platforms according to the learning contents and activities to maximize students' learning satisfaction and achievement.

복수학위/교환학생 프로그램의 활성화로 강좌의 교수진과 학생들이 글로벌화되고 있다. 그동안 기존의 오프라인 위주의 강좌에서 벗어나 온라인 강좌나 블렌디드 학습 기반 강좌가 연구개발 되어 왔다. 하지만 기존의 연구는 대학 내에 국한되어 있어 복수학위나 교환학생 프로그램에 대한 고려는 이루어지지 않고 있다. 글로벌 강좌를 개발하고 운영하기 위해서는 비용이나 효율성 측면에서 여러 가지 어려움이 수반된다. 이를 효과적으로 해결하기 위한 방안으로 온/오프라인을 융합한 블렌디드 글로벌 강좌의 운영이 필요하며 이에 대한 연구가 시급하다. 이를 위해 본 연구에서는 블렌디드 글로벌 강좌 모형을 제시 개발하였다. 해외 석학 중심의 글로벌 강좌 개설 및 운영을 위해 블렌디드 러닝 방법을 반영하여 개설 시기와 온/오프라인 상호 유기적 관계에 따라 크게 8가지로 유형을 고안하고 이들 유형 간의 상호 비교 분석을 하였다. 본 연구에서 제안하는 블렌디드 글로벌 강좌는 글로벌시대에 적합한 인재를 대학에서 양성하는 데 적용할 수 있을 것이다.

Impedance spectroscopy was used to monitor the hydration in the electrical/dielectric behaviors of chemical mechanical planarization (CMP)-blended cement mixtures. The electrical responses were analyzed using their equivalent circuit models, leading to the separation of the bulk and electrode based responses. The role of the CMP slurry was monitored as a function of the relative compositions of the CMP-blended cements, i.e. water, CMP slurry, and ordinary Portland cement. The presence of $Al_2O_3$ nanocrystals in the CMP slurries appeared to accelerate the hydration process, along with a more tortuous microstructure in the hydration, with enhanced hydration products. The frequency-dependent impedance spectroscopy was proven to be a highly efficient approach for evaluating the electrical/dielectric monitoring of the change in the pore structure evolution that occurs in CMP-blended cements.

This research proposes the composition logic of an Active Learning Environment (ALE), to enable discovery by learning through experience, whilst increasing knowledge about modern architectural heritage. Linking information to the historical heritage using Information and Communication Technology (ICT) helps to overcome the limits of previous learning methods, by providing rich learning resources on site. Existing field trips of cultural heritages are created to impart limited experience content from web resources, or receive content at a specific place through humanities Geographic Information System (GIS). Therefore, on the basis of the blended space theory, an augmented space experience method for overcoming these shortages was composed. An ALE space framework is proposed to enable discovery through learning in an expanded space. The operation of ALE space is needed to create full coordination, such as a Content Management System (CMS). It involves a relation network to provide knowledge to the rule engine of the CMS. The application is represented with the Deoksugung Palace Seokjojeon hall example, by describing a user experience scenario.

This study aimed to develop and pilot-test educational program prototypes of training health coaches to help cancer patients overcome crises and create positive growth. For this purpose, the educational contents and methods of the blended learning program prototypes were derived through learner needs and literature analysis. The prototypes, which consist of introducing of health management and health information and understanding and practice of basic coaching and health coaching, were developed to integrate with four sessions of face-to-face, off-line classes, training practices through 12 tele-classes, and use of online learning system. The prototypes were conducted and pilot-tested by a total of 35 students selected through the document screening and the interview. After participating in the blended learning program, learners expressed greater overall satisfaction with each session program (average score = 4.36, with 5 being most satisfied), satisfaction with learning contents (average score=4.42) satisfaction with course preparation (average score = 4.26) and satisfaction with lecture materials (average score = 4.19). The results of this study show that a systematic and integrative approach for designing a blended learning program can be useful for various educational needs in health and medical fields. In the future, empirical studies are expected to see how these curricula are actually implemented and assess whether the intended learning outcomes are achieved.

The paper discusses the effect of the winglets on the aerodynamic and aeroacoustic performance of Boeing 737-800 aircraft by numerical approach. For this purpose, computational fluid dynamics and fluent commercial software are used to solve the compressible flow governing equations. The RANS method and the K-ω SST turbulence model are selected to simulate the subsonic flow around the wing with acceptable accuracy and low computational cost. The main variables of steady flow around the simple and blended wing in constant atmospheric conditions are computed by numerical solution of governing equations. The solution of the acoustic field has also been accomplished by the broad-band acoustic source model. The results reveal that adding a blended winglet increases the pressure difference near the wingtip,which increases the lift force. Also, the blended winglet reduces the power and magnitude of vorticities around the wingtip, which reduces the wing's drag force. The effects of winglets on aerodynamic forces lead to a 3.8% increase in flight range and a 3.6% increase in the maximum payload of the aircraft. Also, the acoustic power level variables on the surfaces and fields around the wing have been investigated integrally and locally.
