  • A military vehicle is driven at different usage modes with the army application and servicing conditions. For practical durability validation, DT(Development Test) on a new military vehicle should be run up to the durability target kilometers on test courses in the specified proving ground. Driving velocities with test courses at the endurance mode of DT are established definitely. However, OT(Operational Test) and initial endurance test of production car can't be performed only in the DT courses due to the development period limit. Therefore, this paper focuses on the method to analyze the relative road damages between the endurance test in DT and other endurance test. Road load acquisition tests on KLTV(Korean Light Tactical Vehicle) were implemented at 15 driving modes in off-road and cross-country courses of two tests. Wheel accelerations were processed through band-pass filter, and then the main frequency and maximum power of the signals were computed by PSD analysis. Finally, using the proving ground optimization based on RDS(Relative Damage Spectrum) characterization, the damage factors between off-roads of test courses were determined.

  • The purpose of this study was to evaluate the basic unit of irrigation water on golf courses in Jeju Island. The amounts of rainwater and groundwater used on 20 golf courses have been monitored for this study. The characteristics of rainwater and groundwater from the selected 20 golf courses were analyzed based on the existing data that had been collected for three consecutive years from 2006 to 2009. The range of monthly irrigation water (groundwater + rainwater) used was about $13,200\sim55,600\;m^3$/month, with average of $36,600\;m^3$/month. In the respects of the amount of annual water used, groundwater was recorded as $163,500\;m^3$/year, and rainwater was recorded as $275,400\;m^3$/year. Thus, the total annual irrigation water used was approximately $439,000\;m^3$/year. The correlation (R2) between golf course lot size and average amount of monthly irrigation water used was 0.65, and the monthly basic unit per golf course area ($1,000\;m^2$) was calculated as $60\;m^3$.

  • What is the "new paradigm"? It is impossible express it in one or two words, but if one had to; the closest might be the "holistic approach". The expression can be justified by the fact that the conclusions above lead to a greater intermixing of mathematics with engineering and natural sciences subjects, typically expressed in the form of examples of simplified real problems. They also lead to a greater intermixing of subjects within mathematics so that the courses should have less separation e.g. between symbolic and numerical mathematics. The conclusions also lead to the spreading the mathematics courses throughout all study years, not just the first two years. Of course, this should be done with great care in order to guarantee studies that are logically linked together. The new paradigm also means that the needs arising from industrial mathematics must be taken into account in the contents of engineering mathematics courses. Such topics are e.g. multivariate methods, statistics and use of mathematical software. What are we expected to gain from the paradigm shift? The primary benefit should be in obtaining more productive engineers equipped with a better degree of mathematical preparedness for engineering problems. But in addition, it should also promote more intensive use of applied mathematics and easier communication with professional mathematicians, often needed in complicated industrial problems.?Finally, it can be noted that the new paradigm is in harmony with the basic ideas of the CDIO (Conceive - Design - Implement - Operate) initiative for producing the next generation of engineers [1]. New ideas for engineering education can be found also in the homepage of SEFI (European Society for Engineering Education) [2].

  • 21세기 들어 온라인 테크놀로지의 활성화로 온라인 강좌와 웹기반 커뮤니케이션의 사용이 고등교육 분야에서 증가되어 왔다. 시간과 장소에 구애받지 않는 온라인 교육의 특성은 대학 캠퍼스를 국내외로 확대하고 대학교육의 수혜자도 일반인과 타대학 학생으로 확대할 수 있는 가능성을 열어주었다. 또한 학령인구의 감소, 대학 구조의 재편과 같은 변화도 온라인 교육에 대한 인식을 바꾸는 계기가 되었다. 본 논문에서는 K대학교 재학생, 고등학교 3학년 학생, 일반인을 대상으로 설문조사를 실시하여 온라인 강좌에 대한 만족도, 대형 온라인 강좌를 필요로 하는 영역, 현재 개설된 대형 온라인 강좌의 운영에 대한 학생들의 니즈 등에 대하여 살펴보았다. K대학교 재학생의 온라인 강좌에 대한 만족도는 높게 나타나고 있다. 다만, 각각의 온라인 강좌에 대한 만족도는 높으나 온라인 강좌의 체계 통일성을 높여야 함과 온라인 강좌를 원활하게 수강할 수 있는 환경 개선이 필요함을 알 수 있다. 고등학생의 경우 자연과학에 대한 선호도에서 일반인과 재학생에 비해 상당히 높게 나오고 있는데 수학, 물리와 같은 과목을 선수과목으로 하고 온라인 강좌로 만들어서 전공 수업에 대비하게 해야 할 필요성이 있다고 생각된다. 일반인의 경우 인문학 분야에 대한 선호도가 고등학생과 재학생에 비해 상당히 높게 나타나고 있는데 이는 교양함양이라는 강의 목적을 통해서도 확인할 수 있다.

  • Microelectronic product consumers may already be expecting another paradigm shift with smarter phones over smart phones, but the current status of microelectronic manufacturing engineering education (MMEE) in universities hardly makes up the pace for such a fast moving technology paradigm shift. The purpose of MMEE is to educate four-year university graduates to work in the microelectronics industry with up-to-date knowledge and self-motivation. In this paper, we present a comprehensive curriculum for a four-year university degree program in the area of microelectronics manufacturing. Three hands-on experienced-based courses are proposed, along with a methodology for undergraduate students to acquire hands-on experience, towards integrated circuits (ICs) design, fabrication and packaging, are presented in consideration of manufacturing engineering education. Semiconductor device and circuit design course for junior level is designed to cover how designed circuits progress to micro-fabrication by practicing full customization of the layout of digital circuits. Hands-on experienced-based semiconductor fabrication courses are composed to enhance students’ motivation to participate in self-motivated semiconductor fab activities by performing a series of collaborations. Finally, the Microelectronics Packaging course provides greater possibilities of mastered skillsets in the area of microelectronics manufacturing with the fabrication of printed circuit boards (PCBs) and board level assembly for microprocessor applications. The evaluation of the presented comprehensive curriculum was performed with a students’ survey. All the students responded with “Strongly Agree” or “Agree” for the manufacturing related courses. Through the development and application of the presented curriculum for the past six years, we are convinced that students’ confidence in obtaining their desired jobs or choosing higher degrees in the area of microelectronics manufacturing was increased. We confirmed that the hypothesis on the inclusion of handson experience-based courses for MMEE is beneficial to enhancing the motivation for learning.

  • 본 연구의 목적은 2022 개정 과학과 교육과정을 앞두고 고교학점제에 대비하여 과학과 융합선택과목의 재구조화 방안을 탐색하는 것이다. 본 연구는 2015 개정 과학과 교육과정의 경우 비(非)이공계열 진로적성을 지닌 소위 문과계열의 학생들의 과목선택권을 보장하지 못한다는 문제의식에서 출발하였다. 이를 위해 2015 개정 교육과정에서 비이공계열 진로적성을 지닌 학생들을 위한 과학과 선택과목이었던 과학사, 생활과 과학, 융합과학을 중심으로 2015 개정 교육과정 운영실태에 대한 학생들의 인식을 설문조사하고, 교사 12명과의 면담을 통해 이들 선택과목의 운영 실태와 개선 방안을 도출하였다. 과학사/생활과학/융합과학 과목은 2022 개정 교육과정에서 과학과 융합선택과목으로 분류, 개정될 예정이다. 연구결과에 따르면 고등학생들은 과학사/생활과학/융합과학을 교양 과학으로 인식하고 있으며, 개인적인 흥미와 노력 부족, 학습내용 자체의 어려움 등으로 이들 과목을 어려워하는 것으로 나타났다. 과학사/생활과학/융합과학 과목의 교육과정 운영 실태를 살펴보면 학생들은 주로 생활과과학을 선택하며, 과학사 과목의 경우 내용이 어려워서 교사도 학생도 기피하는 것으로 나타났다. 연구결과를 토대로 2022 개정 교육과정의 과학과 융합선택과목 재구조화 방안을 간학문적인 핵심개념을 중심으로 한 내용접근성이 높은 융합선택과목 개발, 인공지능(AI)이나 첨단과학 관련 핵심개념을 중심으로 한 융합선택과목 개발, 모듈단위로 구성된 융합선택과목 개발, 간학문적 융합선택과목을 지도할 수 있는 과학교사 전문성 개발지원 등의 측면에서 제안하였다.

  • Biomedical engineering is a discipline where engineering principles and techniques are applied to the medical field. Biomedical engineering lies between traditional engineering and medicine and is an inter-disciplinary field in its nature. Current Korean undergraduate biomedical engineering curriculum is a simple list of traditional engineering courses combined with basic medical/life science courses. There have been efforts to improve biomedical engineering education to reflect its inter-disciplinary nature. Enhanced software course for biomedical engineering is proposed as a part of effort to overhaul the undergraduate biomedical engineering curriculum. In this newly proposed course, students will learn MATLAB and LabVIEW, which are the most widely used software tools in biomedical engineering.

  • As the quality and level of life rise, many people are doing search for various pieces of information about tourism. In addition, users prefer the search methods reflecting individual opinions such as SNS and blogs to the official websites of tourist destination. Many of previous studies focused on a recommendation system for tourist courses based on the GPS information and past travel records of users, but such a system was not capable of recommending the latest tourist trends. This study thus set out to collect and analyze the latest SNS data to recommend tourist destination of high interest among users. It also aimed to propose an altered TSP algorithm to recommend the optimal routes to the recommended destination within an area and a system to recommend the optimal tourist courses by applying the Elasticsearch engine. The altered TSP algorithm proposed in the study used the location information of users instead of Dijkstra's algorithm technique used in previous studies to select a certain tourist destination and allowed users to check the recommended courses for the entire tourist destination within an area, thus offering more diverse tourist destination recommendations than previous studies.
