This study was conducted to examine the effects of simulation-based education on the clinical reasoning competence, clinical competence, and satisfaction with simulation experience (SSE). The research design was one group pretest-posttest. Study participants were 89 third-year nursing students from C University in G city, who were engaged the simulation-based education for eight weeks from August to October 2019. Learning scenario titles were blood transfusion reaction patient care with postoperative total hip replacement, hypoglycemia patient care with diabetes mellitus, and hyperkalemia patient care with liver cirrhosis. The data were analyzed by paired t-test using SPSS Win 23.0 program. After applying simulation-based education, nursing students' clinical reasoning competence (t=-17.082, p<.001) and clinical competence(t=-18.40, p<.001) improved significantly. SSE score was 4.65 out of 5 points. The results indicate that the simulation-based education in this study gave the students the experience of providing qualified and secure nursing care under conditions similar to those in the real clinical field. To improve the clinical reasoning competence and clinical competence of nursing students, various cases scenarios are developed and simulation-based education should be applied to more subjects in the nursing curriculum.

When the parents are unable to control anger properly, it can have a negative effect on their children. Therefore, parents need anger control ability very much. The purpose of this study is to develop a parent education program to improve anger control ability of parents of elementary school children so that it could help them to perform their parental role. The development of the program followed the procedure of analysis, design, development, execution, and assesment. In the analysis stage, previous studies were examined to explore in depth the ways to improve anger control ability. In the design stage, the goals were confirmed and learning objective for each session was defined, and according to this, the contents of education were selected. In the development stage, 8 sessions of education activities were formulated with 2 hours for each session and experts were consulted to examine the validity of the contents. In the execution stage, the operating method was proposed and the program was applied with a total of 8 sessions, 1 session for a week. In the final assessment stage, the effect of the program was assessed. Assessment of the program was carried out by both quantitative and qualitative methods. The quantitative method was verified by pre-and-post comparison, and analyzed by Wilcoxon Signed Ranks Test. For the qualitative method, questionnaire and interview were used.

간호원은 비록 그가 양호교사가 아니라고 하더라도 그가 처한 위치에서 거의 매일 건강교육을 실시하고 있다고 할 수 있다. 그러한 비정규직 교육은 상황에 따라 간호활동의 대상자들에게 수시로 별 준비 없이 실시한 경우도 있겠으나 효율적인 결과를 얻을 수 있는 체계적인 보건교육은 구체적인 학습목적과 교육과정이 교육적으로 미리 계획되어 있어야만 가능하다고 할 것이다. 양호교사의 기본적인 역할이 학교 구성원들의 건강증진과 질병예방에 있으며 효율적인 건강교육을 통하여 이러한 목적을 달성한다고 할 때, 양호교사는 자신을 그 학교공동체의 주된 건강교육자로 이해하고 학교에서 이루어지는 모든 보건교육 과정에 적극적인 참여를 하여야만 한다. 그러한 역할중의 하나는 보건에 관한 수업을 실시하는 학과목 교사나 담임교사들이 건강교육에 관련한 협의를 양호교사에게 요청하도록 적극적인 건강교육환경을 학교 내에 조성하여야 하는 일과 중요한 건강주제에 대하여서는 양호교사가 직접 수업을 교실에서 이끌어야 하는 것일 것이다. 이 논문에서 다룬 보건교육 교안 연구는 양호교사에게 또 건강에 관한 주제를 가지고 수업을 하는 일반교사에게 중학생의 건강교육 과정의 한 모델로써 사용하는데 도움이 될 것으로 본다. 건강교육 프로그램을 질병예방, 건강증진에 초점을 두어 설계한다고 할 때 건강교육의 주된 방향은 대상자 하나 하나의 생활에서 건강을 위한 바람직한 행위를 생활화하도록 하는 것이다. 이 목적을 학교에서 달성하기 위해서는 건강교육 프로그램을 통하여 학생들에게 건강에 대한 지식을 전달하고 그 지식 위에 건강을 위한 바람직한 행위를 하도록 동기를 부여하며 그러한 행위를 지속하도록 보강하는 것이 필요하다고 할 것이다. 사람들은 건강에 대한 지식이나 정보를 가지게 되면, 행위는, 그것에 상응하여 바람직하게 행할 것이라고 가정하기가 쉽다. 그리하여 건강에 대한 정보를 주는 것 건강교육을 했다고 간주하기도 한다. 그러나 실제적으로 건강을 위한 정보를 받고 지식을 가졌다 하더라도 바람직한 행위를 실천하지 않거나, 습관된 반건강 행위를 바꾸지 않는 경우가 많다. 그러므로 건강한 행위를 실천하기 위해서는 그에 대한 가치관이나 태도가 먼저 분명하게 세워져야 한다. 학생들의 경우에도 그 가치관이 확립되어야 하겠으므로 이를 위한 효과적인 교육방법이 제시된 교육안 모델이 있어야 할 것이다. 즉 건강문제에 대한 태도의 확립과 그에 따른 올바른 행위를 실천하도록 하기 위하여 구체적으로 치밀하게 계획된 건강교육 안이 연구되어 지는 것이 건강교육의 가장 중요한 과제중의 하나이다. 이 연구에서 제시하는 건강교육 프로그램에서는 많은 부분의 정보가 학생들 스스로에 의해서 수집되도록 하였다. 그렇게 함으로써 그들이 흡연에 관한 사실들을 스스로 명백하게 파악할 수 있었기 때문이다. 또한 소그룹 토의와 논쟁의 방법을 통해서 학생들이 흡연에 대해서 자신들의 생각하고 있는 것을 검토하여 올바른 판단을 하도록 하는 기회를 가질 수 있도록 하였다.

In the IoT environment, various things could be connected. Those connected things learn and operate themselves, by acquiring data. As human being, they have self-learning and self-operating systems. In the field of IoT study, therefore, the key issue is to design communication system connecting both of the two different types of subjects, human being(user) and the things. With the advent of the IoT environment, much research has been done in the field of UI design. It can be seen that research has been conducted to take complex factors into account through keywords such as multi-modality and interusability. However, the existing UI design method has limitations in structuring or testing interaction between things and users of IoT environment. Therefore, this paper suggests a new UI prototyping method. In this paper, the major analysis and studies are as follows: (1) defined what is the behavior process of the things (2) analyzed the existing IoT product (3) built a new framework driving personality types (4) extracted three representative personality models (5) applied the three models to the smart home service and tested UI prototyping. It is meaningful with that this study can confirm user experience (UX) about IoT service in a more comprehensive way. Moreover, the concept of the personality of things will be utilized as a tool for establishing the identity of artificial intelligence (AI) services in the future.

In this paper, we describe design and implementation of optimal smart home control system. Recent developments in technologies such as sensors and communication have enabled the Internet of Things to control a wide range of objects, such as light bulbs, socket-outlet, or clothing. Many businesses rely on the launch of collaborative services between them. However, traditional IoT systems often support a single protocol, although data is transmitted across multiple protocols for end-to-end devices. In addition, depending on the manufacturer of the Internet of things, there is a dedicated application and it has a high degree of complexity in registering and controlling different IoT devices for the internet of things. ARIoT system, special marking points and edge extraction techniques are used to detect objects, but there are relatively low deviations depending on the sampling data. The proposed system implements an IoT gateway of object based on OneM2M to compensate for existing problems. It supports diverse protocols of end to end devices and supported them with a single application. In addition, devices were learned by using deep learning in the artificial intelligence field and improved object recognition of existing systems by inference and detection, reducing the deviation of recognition rates.

In this study, we investigated the characteristics of pre-service science teachers' curriculum design for lessons using self-generated analogy. Three pre-service science teachers at a college of education in Seoul participated in this study. After a workshop on lessons using self-generated analogy, they planned and demonstrated lessons. All of the teaching-learning materials were collected, and their lessons were observed and videotaped. Semi-structured interviews were also conducted before and after their lessons. The characteristics of lessons using self-generated analogy were analyzed in the perspectives of PCK. The analyses of the results revealed that they used various strategies to promote students' generating analogies. They lacked understanding of the stages of the lessons and the role of teachers. Although all of them considered assessment, they used limited assessment methods and assessment dimensions. Some actively considered students' misconceptions, and specifically anticipated analogies that students could generate. They determined topics for lessons considering various aspects such as the level of self-generated analogy and the characteristics of scientific conceptions. On the bases of the results, we suggest some educational implications for pre-service science teacher education.

In this paper, we propose Genetic Algorithms(GAs)-based Optimized Polynomial Neural Networks(PNN). The proposed algorithm is based on Group Method of Data Handling(GMDH) method and its structure is similar to feedforward Neural Networks. But the structure of PNN is not fixed like in conventional neural networks and can be generated in a dynamic manner. As each node of PNN structure, we use several types of high-order polynomial such as linear, quadratic and modified quadratic, and it is connected as various kinds of multi-variable inputs. The conventional PNN depends on the experience of a designer that select the number of input variables, input variable and polynomial type. Therefore it is very difficult to organize optimized network. The proposed algorithm leads to identify and select the number of input variables, input variable and polynomial type by using Genetic Algorithms(GAs). The aggregate performance index with weighting factor is proposed as well. The study is illustrated with tile NOx omission process data of gas turbine power plant for application to nonlinear process. In the sequel the proposed model shows not only superb predictability but also high accuracy in comparison to the existing intelligent models.

This study redesigned the Korean speaking classes to foreign undergraduate students as flipped learning classes and verified their effect on speaking-related emotional variables. In addition, international students' perceptions of what experiences are needed to improve speaking efficacy in Korean were examined. For this purpose, the 'Creative speaking' subject for freshmen was redesigned to flipped learning class and operated for one semester. To analyze the effect of speech-related emotions, a paired t-test was conducted on 26 foreign students' pre-post scores of speech efficacy and anxiety. Also awareness of experiences needed to improve speech efficacy was surveyed and content analysis was conducted. As the result, the speaking efficacy of students after flipped-learning has been significantly improved. This means that flipped learning classes for the Korean speaking are effective for the positive emotions of foreign students speaking Korean. In addition, international students perceived that Korean speaking efficacy can be improved by practicing speaking in Korean, learning with Korean colleagues. Based on these results, several discussions and suggestions were presented.

As an alternative of making students active and independent under the passive learning conditions in school math classes, many researchers have paid much attention to problem posing and done a lot of research on it. Above all, Brown and Walter proposed What I f Not strategy as a means of problem posing. In this strategy, during the process of posing problems, the transformation of their attributes is inevitably made, and so after problem posing, the process is finished by explaining the problem. But only the simple transformation of attributes could pose wrong problems. It suggests that it is very important to recognize the relationship which leads to organic connection between attributes in order to pose the right problem. However, many other studies of problem posing haven't focused on this fact. Thus, this study tried to design a model of problem posing to help recognize inherent knowledge in the problem and then pose the right problem by adding an activity of meaning analysis. We concretely showed a model of problem posing emphasizing the analysis of meaning by means of an example, thereby examining the meaning of the model. This study expects students to have the chance to understand the true meaning of problem posing and to be active learners after all.

1990 년대 후반부터 다양한 디지털 통신망을 이용하여 멀티미디어 컨텐츠 서비스가 가능하게 되었다. 하지만, 멀티미디어 컨텐츠의 전달 및 이용을 위한 기반 구조들의 독자적 발전 및 다양한 통합적 관리 체계 시스템으로 인해, 멀티미디어 컨텐츠 표현 방식의 호환성 문제, 혼재하는 네트워크 전달 방식과 단말 방식의 호환성 문제 등의 잠재적인 문제점이 발생한다. 이런 문제의 대안으로 현재 존재하는 기술 및 기반 구조들 사이의 연동을 통한 큰 프레임워크인 MPEG-21이 진행 중이다. MPEG-21 의 목표는 표준화 목표를 구체화하는 것부터 진행하여, 최종적으로 “다양한 네트워크 환경과 단말기에 있어서, 투명하고 통합적으로 멀티미디어 자원의 이용을 가능하게 하는 것”이다. 본 논문에서는 현재 표준화 작업이 진행 중인 MPEG-21 을 기반으로 하는 Testbed를 제안한다. Testbed는 server, client, DIA(Digital Item Adaptation) 의 세 모듈로 구성된다. Server 의 역할은 멀티미디어 컨텐츠를 Digital Item(DI)으로 생성하고, client 가 DI를 요구할 경우 DIA 모듈을 통해서 변환된 DI를 client 에게 제공한다. DIA 모듈은 server 에서 동작되며 client로부터 요청된 DI를 분석하고 client로부터 전송된 환경 정보를 이용하여 client 환경에 적합하게 변환된 (adapted) DI를 생성하는 것이 주 기능이다. Client 는 server 에 저장되어 있는 DI를 선택하고 user preference, terminal capability 등의 필요한 정보를 server로 전송한다.
