Purpose: This study was performed to investigate the effects of a blended learning program on ethical values in undergraduate nursing students. Methods: This study was a one group pretest-posttest design. Seventy-one undergraduate nursing students who were taking a nursing ethics course at K University in S city were conveniently selected. The blended learning program was undertaken for 120 minutes one day weekly for 15 weeks. It consisted of case-based learning through an online method combined with problem-based learning offline. Scores for ethical value were measured using the ethical values scale. Results: The ethical values score increased significantly in the students after the blended learning (p=.004). Of the subgroup of ethical values human-life, relationship with collaborator, and nursing job scores increased significantly in students after the blended learning, respectively (p=.034; p<.001; p<.001), the score for area as relationship with nursing clients decreased significantly in the students after the blended learning (p<.001). Conclusion: The blended learning program was identified as an educational program which induces a positive effect on the development of ethical values in undergraduate nursing students, and in future it can be utilized in nursing ethics education.

The present study is focused on the mechanical and durability properties of ternary blended cement concrete mix of different grades 30 MPa, 50 MPa and 70 MPa. Three mineral admixtures (fly ash, silica fume and lime sludge) were used as a partial replacement of cement in the preparation of blended concrete mix. The durability of ternary blended cement concrete mix was studied by exposing it to acids HCl and $H_2SO_4$ at 5% concentration. Acid mass loss factors (AMLF), acid strength loss factor (ASLF) and acid durability factor (ADF) were determined, and the results were compared with the control mix. Chloride ions penetration was investigated by conducting rapid chlorination penetration test and accelerated corrosion penetration test on control mix and ternary blended cement concrete. From the results, it was evident that the usage of these mineral admixtures is having a beneficiary role on the strength as well as durability properties. The results inferred that the utilization of these materials as a partial replacement of cement have significantly enhanced the compressive strength of blended concrete mix in 30 MPa, 50 MPa and 70 MPa by 42.95%, 32.48% and 22.79%. The blended concrete mix shown greater resistance to acid attack compared to control mix concrete. Chloride ion ingress of the blended cement concrete mix was low compared to control mix implying the beneficiary role of mineral admixtures.

Purpose: The purpose of this study is to investigate the analysis blended learning interesting and satisfaction on students majoring in dental techniques. Method: The study subject were 181 students from Gimcheon university. Data for this survey was obtain by self-administration method. This questionnaire consist of $lecture^{\circ}$Øs interesting and satisfaction when using an blended learning in the lecture. SPSS 22.0 was used. Analysis of frequency was used and two sammple t-test was used to identify significantly different blended interesting and sataisfaction within the grade. Multiple regression was used to which interestings affect the satisfaction. Results: First, there were significant differences in the grade among the blended interesting and sataisfaction, while on differences in participation satisfaction(p<0.05). Second, The correlation coefficient is 0.714 between blended interesting and staisfaction, Third, Multiple regression showed that the $lecture^{\circ}$Øs interesting applying blended learning affects the satisfaction(p<0.05). Conclusion: Given the findings of the study, lecture applying blended learning seem to be efficient education programs to improve lecture's interesting & satisfaction.

The purpose of this study is to compare and analyze the impact on low-achievers in mathematics who studied mathematics using Blended e-learning and Personalized system of instruction after school. Blended e-learning is defined as the management of e-learning using the e-study run by the education office in local. Personalized system of instruction was proceeded as follows; (1) all students are given a syllabicated learning task and a study guide, (2) students study the material autonomously according to their own pace for a certain period of time, (3) the teacher strengthens the students' motivation through grading and feedback after students study a subject and solve the evaluation problem. The learning materials for Personalized system of instruction are re-edited the offline education contents provided by the blended e-learning to the level of students. The 118 $7^{th}$ grade students from the D middle school participated in this study. The results were verified by achievement tests before and after the study, as well as survey regarding their attitude toward mathematics. The results are as follows. First, Blended e-learning has more positive impacts than Personalized system of instruction in mathematics achievement. Second, there was no difference in mathematics achievement according to their self-directed learning between Blended e-learning and Personalized system of instruction. Third, both types utilizing Blended e-learning and Personalized system of instruction have positive effect on attitude toward mathematics, and there is not their difference between two methods of teaching and learning mathematics.

In this study, durability performance of blended cement mortars is evaluated when various mineral admixtures are used with the cement. A comprehensive evaluation of the effects of mineral admixtures on the mortar performance was made. The properties of fresh and hardened blended mortars investigated include slump flow and compressive strength. The durability characteristics of cement materials incorporating the mineral admixtures under various physical and chemical causes of deterioration was investigated. The laboratory test results indicate that mechanical and durability properties of blended cement mortars have superior performance rather than ordinary cement mortars.

Expectations and interests in blended learning are increasing as universities respond to the educational flow of transition to e-lernring. This study tried to explore and understand the meaning of and the properties of blended instruction. In addition, through the literature review, this study was to find out how bleanded learning affected in teaching and learning situation. Particularly, it was to find out students' preference to the type of blended instruction. Those types are the mixed of or the unique of class instruction(off line), on line, and recorded instruction. To investigate learners' preference to the type of the instruction and also the reason of the preference, in this study, the 27 undergraduate students of the fourth grade in the major of mathematics education in the C university located in G area. By the result, most students preferred the mixed type of instruction involving off line and recorded instruction. The reason is that they could attend to the class while participating in the group activity positively and understand the content through the communication in depth and the instructor's feedback. Because of this reason, they did not prefer to the only one type insturction such as the recorded type.

협력학습이 효과적인 교수모형으로 인식되고 있고, 최근 기본적인 학습 환경은 면대면 강의실 환경일지라도 e-러닝 환경의 장점을 부가적으로 활용하는 혼합학습 형태의 수업이 급격히 증가하고 있음에도 불구하고아직 협력학습을 위한 체계적인 혼합학습 전략에 대한 연구는 많이 부족하다. 이 연구에서는 면대면 환경에서의 협력학습 모형을 기반으로 혼합학습 전략을 개발하고, 실제 학습 현장에 적용하여 수업의 만족도를 알아보기 위한 설문을 실시하였다. 설문 내용은 학습자 기초 조사를 위한 문항, 수업 전반에 대한 만족도, 혼합학습 환경에서의 협력학습에 대한 만족도, 협력학습 각 단계에 적용된 혼합학습 전략 및 지원도구에 대한 만족도 등의 문항으로 구성하였다. 이 연구의 결과는 다음과 같다. 첫째, 혼합학습이 면대면 강의실 수업의 부족한 부분을 보완할 수 있겠는가에 대한 응답자들의 답변은 5점 Likert scale의 평균 4.09로 조사되었고, 혼합학습 환경에서의 협력학습이 면대면 환경에서보다 더 효과적이었는가에 대한 답변은 평균 4.06으로 조사되었다. 둘째, 협력학습의 각 단계에서 적용한 혼합학습 전략과 지원도구의 활용에 대한 만족도는 모든 문항에 대해서 평균 4.0이상으로 만족도가 매우 높게 조사되었다. 셋째, 혼합학습 전략에서 사용된 지원도구 중 학습자들이 가장 유용하다고 인식하는 순서는 채팅, 팀별 커뮤니티, 메일&쪽지, 자료실 순으로 조사되었다. 마지막으로, 향후 학습관리시스템의 협력학습 모듈을 설계할 때에는 이와 같은 연구 결과를 적극 반영해야함을 제언하였다.
