This study reviewed published studies on interventions used by hospitals, health insurance programs, or governments to improve use of medicines in foreign countries. Interventions to improve use of medicines are classified into two categories: 1) information strategies-dissemination of educational materials, group education, one-to-one educational outreach, drug utilization review, and feedback; 2) managerial strategies- formularies, prior authorization, and financial incentives. Dissemination of educational materials, which is a common intervention, was unsuccessful in changing physicians' prescribing behaviors. Problem-based small group education was more likely to change behaviors than didactic large group education. One-to-one educational outreach(academic detailing) was among the most effective strategies used to change prescribing behaviors. Prospective drug utilization review (DUR) program was more successful in improving use of medicines than retrospective DUR program. Feedback intervention has been reported to be ineffective to change behaviors. Formularies are frequently used to control medication use by most health insurance programs. Financial incentives provide physicians economic incentives according to appropriateness of prescribing. However, few published studies have assessed the efficacy of formularies or financial incentives. Prior authorization requires physicians to get authorization from health insurers before prescribing a certain group of drugs which is usually of high costs or risk. There is no magic bullet for quality use of medicines. Multifaceted interventions that help to predispose, enable, and reinforce desired behaviors are more likely to be successful.

본 연구에서는 영어쓰기에서 활용되고 있는 온라인 자동쓰기평가 프로그램을 활용하는데 있어서 학생들의 인식 및 태도를 살펴보는데 목적이 있다. 이를 위해 총 131명이 참여하였고 참여자는 대학교 1학년 초급수준의 학습자들로 구성되어있다. 연구도구로는 사전·사후 설문지, 사전·사후 테스트 그리고 학습저널의 자료가 수집되고 분석되었다. 연구는 2019년 2학기, 총 15주에 걸쳐 실시되었으며 그 결과는 다음과 같다. 첫째, 설문에 참여한 학생들은 스스로 영문법에 어려움이 있고 영작문에 있어서 피드백이 도움이 된다고 생각하고 있었다. 둘째, Grammarly 활용에 있어서 학생들은 전반적으로 긍정적인 태도를 보이고 있었다. Grammarly는 영어학습과 과제수행에 도움이 되었고 활용도 면에서도 높게 나타났다. 마지막으로 사전·사후 문법테스트에서 Grammarly의 효과성은 유의미한 결과를 보였다. 본 연구결과를 토대로 한 제안점은 다음과 같다. 첫째, 학생들이 프로그램을 적극적으로 활용할 수 있도록 익숙해지는 시간을 갖도록 해야 한다. 둘째, 교사는 학생들에게 AWE(Automated Writing Evaluation)의 피드백이 항상 정확하지만은 않다는 것을 이해하도록 해야 한다. 마지막으로 교사의 피드백이 반드시 함께 제공되어야 한다.

이 논문은 지능구조물의 실시간 적응진동제어를 위해 유전자 알고리즘을 이용하여 Positive Position Feedback(PPF) 제어기를 조정하는 것과 관련이 있다. 유전자 알고리즘은 최적변수를 찾는데 있어 국소 최소점이 아닌 전체적인 최적점을 찾을 수 있는 능력이 있다. PPF 제어기는 다른 진동모드에 영향을 주지 않으면서 특정 진동모드의 감쇠를 증가시킬 수 있는 장점을 가지고 있는 반면에 효과적인 진동제어를 위해서는 제어하고 자하는 진동모드의 고유진동수를 정확히 알아야하는 단점이 있다. 본 연구에서는 유전자 알고리즘을 이용하여 실시간으로 PPF 제어기가 필요로 하는 변수값을 추적할 수 있는 알고리즘을 개발하여 그 타당성을 실험으로 증명하였다. 실험결과는 PPF 제어기의 실시간 조정이 성공적으로 이루어져 진동제어가 효과적으로 이루어졌음을 보여주고 있다.

본 연구에서는 게임 콘텐츠를 적용한 시각 피드백 훈련 프로그램을 이용하여 정상 여성 고령자와 정상 20대 성인의 자세균형 조절의 효과를 분석 하였다. 실험은 힘판 기반의 자세균형 훈련 장치를 이용하여 20대 성인 23명과 60대 고령자 14명은 주 3일, 하루에 15분씩 총 4주의 자세균형 훈련을 받았다. 자세균형 훈련에 대한 평가는 Balance SD(Biodex, medicalscience Inc., USA)의 자세 안정성과 자세 한계성을 분석하였으며, 훈련 전, 중, 후의 각 시점에 대한 유효성을 검증하였다. 실험 결과, 젊은 성인과 고령자 모두 훈련 전, 후에 자세안정성과 자세한계성에 유의한 효과가 있었음을 확인하였다(p<0.05). 이는 자세 균형게임은 자세 균형과 관련된 전 후 좌 우 다양한 방향에서의 무게 이동 능력을 향상시켰음을 알 수 있었다. 게임 기반 시각적 피드백 훈련은 자세균형에 효과적으로 적용가능하며 개인과 다양한 연령층에 맞는 맞춤형 콘텐츠 개발이 필요할 것으로 사료된다.

It is necessary to evaluate the greenhouse gases (GHGs) reduction policy by central and regional governments to set up the suitable GHG emissions measures. Quantitative, qualitative and synthetic methods have been adopted by previous researches to estimate GHG reduction policy. However, these methods mostly focused on the results of the reduction policy, rather than understanding and fixing the integrated structures of GHG emissions. In this research, System Dynamics(SD) was applied to 1 million green homes program, self-carfree-day system and carbon point program. The results showed that SD analyses could be appliable for the estimation of GHG reduction policy by developing the feedback loops and dynamic simulation model. SD can be consider as a supplementary tool to estimate the GHG reduction policies through the recognition of the structure in complex real system.

Objectives: The purpose of this study was to evaluate the effects that appeared to parents after conducting a dental caries management program for 12 months using a mobile application for systematic caries management of children. Methods: Parents responded to a questionnaire on oral care self-efficacy and oral health knowledge at the baseline, and received feedback on a management program suitable for their child's caries risk group for 12 months through a mobile application. At the end of 12 months, the questionnaire was re-written. Results: The self-efficacy of oral care increased in the low risk group, and oral care knowledge and program satisfaction were highest in the parents of low risk children. Conclusions: Base on the results of the this study, It was confirmed that parents' self-efficacy, knowledge, performance and satisfaction were all positively evaluated through the oral care program using a mobile application.

The effects of the Attachment Promotion Therapy (APT) program for the autistic children were reviewed by 8 papers. The program was consisted with play activity centered mother-child interaction, educational activity for parents, lecture, video-feedback, and support. APT program was effective to improve the attachment behaviors and attachment security. And the mother's behaviors to her child became more child-centered, positively responsive, expressive supportively. Ninety six point seven percent of the mothers were satisfied with the APT program. They described that it was helpful to understand their children's developmental limitation and strength, to learn how to play with their children, to make supportive social network among the mothers, to minimize familial conflicts, and to make them much more comfortable with their children. They thought the APT Program was to be a steppingstone of the further educational program. APT program is an effective early intervention to promote social development and decrease autistic problems.

Purpose: The purpose of this study was to develop an e-Learning program about medication for nurses to enhance nurses' medication performance ability and to analyze learners' responses after studying with this program. Method: For the development of the e-Learning program, the NBISD(Network Based Instructional Systems Design) model, suggested by Jung(I999) was applied as a basic model and the instruction design theory of Gagne & Briggs(1979) and ARCS theory of Keller(I983) were applied. After the operation of this program for one month to 34 new nurses, learners' responses were analyzed. Result: Learners' knowledge of medication was greatly improved after this program. In addition learners' satisfaction with the overall education program, help in field applicability, ease of screen shift and exploration, and tutor activities were high and the contents were regarded suitable for e-Learning. Many things were advantageous such as easy accessibility, easy understandability with pictures and flash animation, practical cases and feedback from a tutor. Provision of a supplementary handout and improvement of a tight time schedule were pointed out as things to be improved. Conclusion: This e-Learning program can be used effectively for medication education for registered nurses, student nurses, and new nurses.

Purpose: The purpose of this study was to develop a program outcomes assessment system based on Course Embedded Assessment for nursing education. Methods: This study was conducted in accordance with the procedures of the developmental research method. Results: The major results are as follows. 1) The program outcomes were measured according to the Analytic Hierarchy Process. 2) The Course Embedded Assessment matrix was made according to program outcomes' weight, the curriculum-organizing principle, and achievement levels. 3) The Course Embedded Assessment rubric was developed in logical process, and consisted of a performance criterion, and rating scale. The content validity index of the Course Embedded Assessment rubric was 0.85. 4) An evaluation guideline and 12 documents were developed to facilitate the performance of the assessment system. 5) The average content validity index of the Course Embedded Assessment-based program outcomes assessment system was as high as 0.89. Conclusion: A Course Embedded Assessment-based program outcomes assessment system is more suitable for accreditation of nursing education than previous studies. Because this system evaluates the process of achievement as well as program outcomes, the results can also serve as immediate feedback to improve the educational process. Above all, this system facilitates that students check their achievements and strive to acquire core competencies in nursing.
