The purpose of this study was to emphasize the household financial education as a part of family life education, especially when provided at local community level; it also examines diverse measures by which to deliver such education. To this end, the current study focuses on the education programs of a healthy family support center, which has been established as a representative transmission system. The current status of its operations was examined, and practical measures by which to stimulate the delivery of financial education within that center were derived. In more detail, previous studies inside and outside of Korea were examined, and the current status of financial education included in the area of family life education was assessed; as a result of these assessments, the definition and objectives of financial education as family life education were adjusted. The limits of financial education that has been delivered thus far were reviewed, with the aim of proposing measures by which to sufficiently stimulate the delivery of financial education programs-programs that ultimately reflect the healthy family philosophy. This study proposes four specific measures by which to stimulate financial education. The first is the application of 'life cycle perspectives' to educational terms. The second is the activation of financial education programs that involve the family unit as educational subjects. Third, the delivery of lectures which related to the financing and nurturing of program coordinators was proposed. The fourth is drawing a connection between online and offline education in terms of effectively applying teaching methods. Ultimately, the results of this study can be used as basic data to inform the planning, development, and operational stages of financial education programs within family life education, which can be performed in healthy family support centers in the future.

본 연구의 목적은 소수 나눗셈을 도입하는 수업에서 아동들이 소수 나눗셈을 이해하는 과정을 분석하고 소수 나눗셈 학습과 관련한 어려움을 극복하는 과정에서 아동들이 전개하는 논리적 추론의 특징을 분석하는 것이다. 초등학교와 중학교 수학에 어떤 차이점이 있다면 그것은 논리적 추론의 특성에서 찾을 수 있다. 따라서 초등학교 고학년 아동의 논리적 추론의 특성을 탐구할 필요가 있으며 이를 위해 본 연구에서는 초등학교 5학년 아동을 대상으로 (자연수)${\div}$(소수) 학습을 하면서 나타나는 논리적 추론의 특성을 규명하였다. 연구 결과 5학년 아동들은 구체적 조작 수준을 넘어 가설-연역적 추론의 수준을 경험하면서 형식적 조작기의 특성을 보였다. 그리고 두 종류의 가역성 가운데 상반성에 기초한 아동의 설명은 소수 나눗셈과 관련한 어려움을 극복하는데 효과적이라는 것과 함께 이런 가역성은 아동들이 곱셈과 나눗셈을 같은 연산 체계로 이해할 수 있게 함을 알 수 있다.

Generally, a PLM education program in university consists of lectures of theory, software lab and software development raining as an advanced subject. Most industries want more than these, such as practical problem solving capabilities, teamwork skills and engineering communications including human relationship, rhetoric, technical writing, presentation and etc. Problem-Based Learning is a problem-stimulated and student-centered teaming method, and an innovative education strategy for collaborative and self-directed learning by applying real world problems. Education paradigm changes from "teaching" to "learning" accomplished by team working, and students are encouraged to develop, present, explain and defense their ideas, suggestions or solutions of a problem, and the "cooperative teaming" proceeds spontaneously during team operations. Co-operative education program is an into-grated academic model and a structured educational program combining classroom learning with productive work experience in a field related to a student's academic or career goals. Based on the partnership between academic institutions and industries, students are engaged in real and productive "work" in the industry, in contrast with merely observing. In this paper, PBL with Co-op program is suggested as an effective approach for PLM education, and we made and operated a PBL-based education course with industry co-op program. The Co-op education in industry accompanied with the PBL course in university can improve practical problem solving capabilities of students, including modeling and management of P3R(Product, Process, resource and Plant) using commercial PLM software tools. By the result, we found this to be an effective strategy for helping students, professors and industries succeed in engineering education, especially PLM area.

The school classroom is a common living place where students spend 7 to 14 hours a day to prepare for their careers. Therefore, if the ventilation of the classroom is not properly performed, it may lead to the deterioration of learning ability due to the unclear air. The concentration of carbon dioxide in the classroom is reported to be high, and the increase in carbon dioxide concentration has a negative effect on the learner's academic performance. In this context, the purpose of this study is to propose a methodology for intelligent and responsive window opening-closing operation process that can reduce the concentration of $CO_2$ in the classroom in order to build a support space that can create an effective teaching-learning environment for adolescents. The specific objectives are as follows. First of all, we define the concept of window opening-closing operation. Secondly, twe develop the operation process of window opening-closing. Thirdly, we develop an algorithm for real-time window opening and closing (process) (Window Opening-Closing Operation Process). Finally, we verify the intelligent responsive window opening-closing operation process through developing examples of window opening-closing operation process using the parametric design program. This study is a preliminary study to develop algorithms necessary for window opening-closing operation. Based on the first-order algorithm, We simulated window opening-closing operations according to a hypothetical scenario. As a result, This study can show that the window is open and close depending on the $CO_2$ concentration, but the $CO_2$ concentration in the room is higher than outdoors. Consequentially, we suggest that it is necessary to develop an algorithm to supplement these results because window is often not working when the temperature difference between indoor and outdoor in winter is large.

The main purpose of this research is to find out whether curriculums of industrial engineering (IE) departments meet the demand of IE graduates working in various fields. The research was conducted as an online questionnaire survey selecting IE Graduates working in industries as practising engineers. 1,324 participants were validated among 1,477 participants. 13 fields were selected and used in the survey. Those were; 1) Mathematical statistics, 2) Computer, 3) Purchase, 4) Production system, 5) Logistics, 6) Marketing, 7) Monetary, 8) Experiment methods, 9) Operations Research (OR), 10) Human Factors, 11) Quality, 12) Engineering management, and 13) Information systems. Using the 5-scale Likert rating, each education subject was assessed both in terms of its usefulness in practices and the amount it being taught in school. As a result, courses such as motion/time study, linear programming that IE has traditionally focused showed less usefulness in practices while it is taught in relatively large amount in schools. However, courses such as 6 sigma, CRM which are closely related to industrial practices showed high usefulness in practices compared with low degree of teaching in school. This was the first ever large scalesurvey conducted for IE graduates in Korea. The result of survey displayed many helpful information on current status and future direction of IE education in Korea.

The purpose of this study is to analyze the 6th graders' understanding of the concepts of variable on various aspects of school algebra. For this purpose, the test of concepts of variable targeting a sixth-grade class was conducted and then two students were selected for in-depth interview. The level of mathematics achievement of the two students was not significantly different but there were differences between them in terms of understanding about the concepts of variable. The results obtained in this study are as follows: First, the students had little basic understanding of the variables and they had many cognitive difficulties with respect to the variables. Second, the students were familiar with only the symbol '${\Box}$' not the other letters nor symbols. Third, students comprehended the variable as generalizers imperfectly. Fourth, the students' skill of operations between letters was below expectations and there was the student who omitted the mathematical sign in letter expressions including the mathematical sign such as x+3. Fifth, the students lacked the ability to reason the patterns inductively and symbolize them using variables. Sixth, in connection with the variables in functional relationships, the students were more familiar with the potential and discrete variation than practical and continuous variation. On the basis of the results, this study gives several implications related to the early algebra education, especially the teaching methods of variables.
