Recently, as awareness of the need for software education has spread worldwide, the government of Korea has led compulsory software education also. Basic software education in universities has been stabilized through various trials and efforts. However, due to software classes are mandatory, students not only could not have motivation for learning but also have treated programming course as a difficult subject. In this paper, two programming classes, which were designed and managed as a problem-oriented programming class for the purpose of cultivating computational thinking for the non-computer science students, are compared using the lecture assessment results. As a result, in the case of expanding the use of the problem as a grammatical explanation aid and expanding the ratio of major-friendly problems, the student's responses were concentrated on higher scores and the response average improved by about 7%. It means that the level of difficulty experienced by learners is lowered.

Animation tool has been made changes rapid development of animation from analog tool to digital authoring tool. Depending on the change in the status of digital authoring tools, education of digital authoring tool has brought many changes occurred in the institute and university. Digital authoring tool was insufficient for research of authoring tool due to the recognition that authoring tool is a simple tool. I try to resolve the difficulties through the analysis digital authoring tools to students studying at the university. In addition, Suggests social/cultural change of animation practitioners and effective training methods of digital authoring tools in the education of beginners and practitioners. This tool have perceptual knowledge and narrative knowledge. Since the language features and knowledge features is difficult to learn. it must be learned knowledge of computer graphics of professional level properly to learn. Then users should try to be creative within the authoring tool to produce creative results. also formed the community and to exchange information for self-development further it should form job market that authoring tool make formed through medium. So, I think that there is a need to change academically attitude to authoring tool. because this is not only the positive side but it occurs phenomenon to enslave users in authoring tool, and blind faith in the authoring tool or critical stance on software. It was a lot of pre-existing research that investigate engineering and industrial side in the authoring tool. Through this thesis, We will find social/cultural features and academic significance, and investigate that how to approach the method of education.

The recent corporate economy, such as the COVID 19 pandemic that has spread all over the world since the beginning of 2020, the acceleration of the 4th industrial revolution, and supply chain management risks triggered by the US-China conflict and the Ukraine crisis, is more serious than ever before. CEOs who have started and managed small and medium-sized enterprises (SMEs) are more concerned than ever about the sustainability of their businesses in this reality. Nevertheless, there were few empirical studies on the factors that influence the intention of SME CEOs to discontinue business. In this study, the perception of the business environment of SMEs (intensity of competition in key business areas, difficulty in manpower management), corporate competency (employee competency, company product or service competitiveness, supply chain and consumer relations, digital competency and technical expertise), and CEO's competency(trust between employees and the CEO, management competency and perceived health status of CEO) on CEO's intention to discontinue business was discussed. As a result of the study, the intensity of competition in the main business field, and the difficulty in manpower management had a positive (+) effect on the intention to discontinue the business, and the employee competency, product (service) competitiveness, digital competency of the company, and the CEO's Health status had a negative (-) effect on intention to discontinue business. The relationship between these influences was found in the order of CEO's health status, product competitiveness, employee competency, digital competency, competitive strength in the main business, and difficulty in manpower management. It was analyzed that supply chain and consumer relations, trust between employees and the CEO, and management capabilities did not significantly affect the intention to discontinue business. On the other hand, business confidence has a mediating effect between the intensity of competition in the main business field, the difficulty in manpower management, product or service competitiveness, digital competency, trust between employees and the CEO, and the management capability and intention to discontinue business was tested. This study had academic significance in that it empirically analyzed factors related to intention to discontinue business targeting small and medium-sized business CEOs. In practice, as it has been found that business environment awareness, corporate competency, managerial competency, and business confidence are factors that influence the intention to discontinue business, if an action ideas that can reinforce this part can be found, SMEs can achieve sustainable growth or it may help CEO find an meaningful exit.

Recently, there has been a growing interest in SW education for non-SW major in order to nurture SW convergence talent. In Korea, it is a tendency to make SW mandatory for basic education to all students regardless of their major, starting with SW-oriented universities. Through a case study of programming lesson, the paper compared differences in academic achievements and difficulties of learning between SW majors and non-majors and between the humanities department and the science department. As a result, although there was no significant difference in academic achievement according to majors, the humanities department had more difficulty in implementing programs such as practices, assignments, and team project. Through the interview, lack of understanding about programming problem itself, lack of relationship with friend or tutor that can help assignments, and difficulty in learning motivation by piecemeal curriculum knowledge alone were the main causes. The results will be expected to propose the direction of SW education for non-SW majors.

2020년은 장마와 태풍으로 인해 중부 및 남부지방에 폭우가 발생하여 강남역을 비롯한 지하철 역사와 지하 주차장 등 많은 지하시설이 침수되었고, 부산에서는 침수된 지하차도에 진입한 차량의 운전자가 사망하는 등의 사고가 발생하였다. 지하에 설치된 시설들은 침수가 발생할 경우 대부분 출입구를 통해 유입되는 물을 거슬러 대피해야 하므로 낙상과 그로 인한 익사 등 자칫 큰 인명피해를 초래할 수 있어 특별히 주의할 필요가 있다. 대피 여부를 결정하고 그에 필요한 시간을 계산하기 위해서는 안전하게 대피 가능한 최대수심(한계수심)을 결정하는 것이 필요하다. 현재 한계수심을 제시한 여러 연구가 있지만 대부분 소수의 성인만을 대상으로 한 실험 결과이기 때문에 성별, 연령, 체중 등 다양한 유형의 사람을 고려한 대피방법 제시가 필요하다. 이에 본 연구에서는 실험 참가자의 유형(성별, 연령, 체중, 신장)에 따른 대피시간의 차이를 고려한 한계수심을 제시할 수 있도록 하였다. 총 308명이 실험에 참여하였으며, 이중 남성은 164명, 여성은 144명이었다. 참가자의 연령은 14세부터 75세까지이며, 신장은 최소 145cm에서 최대 187cm, 체중은 35kgf에서 110kgf 범위이다. 대피시간은 물이 흘러 내려오는 5.1m 길이의 계단을, 난간을 잡은 채 거슬러 올라가는 시간으로 설정하였으며, 계단 상층부의 수심이 30cm일 때와 40cm일 때(한계수심 조건), 2회 측정하였다. 또한, 측정이 종료된 후, '안전하게 대피 가능할 것으로 예상되는 수심'을 선택하도록 하여 참가자가 체감한 실험 난이도를 간접적으로 확인하고 향후 연구에 활용할 수 있도록 하였다. 수집된 자료를 분석한 결과 여성의 경우 수심 30cm와 40cm의 평균 대피시간이 4초 정도의 차이가 나타났으나, 남성의 경우 유의미한 차이가 나타나지 않았다. 또한 '안전하게 대피 가능할 것으로 예상되는 수심'에 대한 답변으로 다수가 실험의 최대 수심 조건인 40cm 이상을 선택하였다. 이와 같은 결과를 보아, 실험의 난도가 높지 않았다고 예상할 수 있으며, 그 원인은 참가자의 안전을 고려해 실험 조건을 난간을 잡은 채 보행하도록 설정한 것이 한계수심을 증가시키는 결과를 가져왔다고 볼 수 있다. 유형에 따른 대피시간의 차이를 분석하기 위해서는 실험의 한계수심 조건을 높이거나, 난간을 잡지 않고 보행할 수 있도록 안전장치를 추가하는 등, 실험조건의 변화가 필요할 것으로 판단되며, 추가적으로 난간을 잡은 채 보행하는 것이 한계수심을 얼마나 높일 수 있는지에 대한 검토를 통하여 정량적인 대피가능 시간을 제시할 수 있을 것으로 사료된다.

Recently, with an emphasis on software proficiency, universities are providing software education to all students regardless of their majors. However, non-majors often lack motivation for software education and perceive the unfamiliar learning content as more challenging. To address this issue, tailored software education according to the learners' characteristics is essential. Art students, for instance, with their strong visual comprehension and expressive abilities, can benefit from utilizing visual literacy to enhance the effectiveness of programming education. In this study, we propose decomposing everyday problems into flowcharts and pseudocode to construct procedural and visual images. Using the educational programming language PlayBot, we aim to analyze the effectiveness of teaching by coding to solve problems. Through this approach, students are expected to grasp programming concepts, understand problem-solving processes through computational thinking, and acquire skills to apply programming in their respective fields.

By using the concept of 'Resonance' in benzene which stems from a unit dealing with the carbocyclic compounds which is in a text 'Chemistry I', I developed teaching methods based on the history of science. This study was executed to analyze the effect by applying these methods. Seventy 3rd grade male students, who are attending a high school located in the Pohang area were used in this study. I investigated the level of the relative difficulty and the degree of scholastic achievement from each treatment group and controlled group using the concept of Resonance from the preceeding study. In this study, these 70 students divided into two classes- a traditional lecture group consisting of male 35 student, and a group using the history of chemistry consisting of the remaining 35 student and after a specified period, their scholastic achievement was analyzed. As a result of this study, the treatment group scored much higher (50.143) than the controlled group(25.429) in average score and showed significant difference between two groups. Through this study was based on the history of chemistry, after scientists let them realize the process of improving science attitude, and think like scientists, giving conceptual class can get much more efficiency and durability for learning.

In this study, the definition, the level of difficulty, and the certainty of the understanding of 113 astronomy terminologies from 2009 revised middle school geoscience textbooks were examined. And through further interviews, the types of students' misconceptions about astronomy terminologies and their representative terms - examples of misconceptions were analyzed. The definitions of the terms presented by the students were largely classified as correct, low-level, and incorrect understanding. And low-level understanding was subdivided into high-level definition descriptions, undifferentiated concepts, and incorrect answers were subdivided into interference by scientific misconception and lack of prior knowledge. Given that the misconceptions due to terminologies can be distinguished from the prior misconception, the misconceptions due to terminologies can be effectively prevented by changing the term itself. In addition, students were aware of the advantages and disadvantages of metaphorical terms, and the recognition of their level of understanding is expected to be a good starting point considering that recognizing their own misconceptions is the first step in correcting them. Terminologies in science education is always an important subject of discussions, striving to select the right term according to the times, and scientific terms may change. It is expected that the results of this study will be the basis for discussions on the modification of terms.
