In this paper, mechatronics education in South Korea is analyzed and its improvement is proposed. For this purpose, discussion on the definition and evolution of mechatronics in South Korea, USA and EU is deployed first. It is revealed that most of the mechatronics education in USA and EU is remained in cross-disciplinary stage or curriculum stage, whereas that in South Korea is evolved to curriculum stage or organizational stage. The comparison of mechatronics curriculum between Korea and other countries and the problems of mechatronics education are included. The automation of machinery and factory plays one of major roles in mechatronics education in Korea, while mechatronics curriculum in USA and EU does not emphasize the automation. Mechatronics experiment in South Korea is organized to meet the National Qualification Test on mechatronics, and it is recommended to be more inventive. The way of improving the National Qualification Test of South Korea on mechatronics field is proposed. And, finally, efficient way of linking technical high school and university in mechatronics education is also proposed.

Although mechatronics education in a mechanical engineering curriculum is recently recognized as important, its experimental education has been done generally in the laboratory equipped with all the apparatus and could not be done at home by students. This paper introduces experimental educations on mechatronics, e.g., digital logic circuits, 7-segment LED drive, square wave generation, microcontroller programming using assembly and C languages, timer interrupt, and step motor drive using a small 5 V power supply, a breadboard, various electronic and electric components, a microcontroller and its programmer, a step motor, and a student's PC. In the developed mechatronics course, experimental educations are scheduled in parallel with content's lectures together, and cheap and economic experimental environment is prepared for students in which students can easily practice experimental works in advance or later at home by themselves.

The semiconductor and display equipment demands an ultra-fine precision of several nm to several ㎛, and the scale is getting smaller due to the explosive development. The manufacturing process equipment for such products with ultra-fine precision is very sensitive to ultra-small vibrations flowing from the floor, resulting in problems of production defects and yield degradation. The vibration criteria are a standard that regulates the vibration environment of the floor where such precision process equipment will be installed. The BBN vibration criteria defined the allowable vibration velocity level in the frequency domain with a flat and inclined line and presented a rating according to it. However, the actual vibration criteria have appeared with various magnitudes in the frequency domain according to the dynamic characteristics of individual equipment. In this study, the relationship between the relative motion of two major points in the equipment and the vibration magnitude of the floor is presented using the frequency response function of a simple 3-DOF model. It is describing the magnitudes according to the frequency of the floor vibration that guarantees the allowable relative motion and this can be used as the vibration criteria. In order to obtain the vibration criteria experimentally a method of extracting through a modal test was introduced and verified analytically. It provides vulnerable frequency and magnitude to floor vibration in consideration of the dynamic characteristics of individual equipment. And it is possible to know necessary to improve the dynamic characteristics of the equipment, and it can be used to check the vibration compatibility of the place where the equipment will be installed.

In this paper, we investigated the problems and solutions in the production of scaffolds using commercially available FDM 3D printers. We used ADRIGE TRIZ algorithm to systematically analyze the problems and suggest solutions. We printed scaffolds using suggested solutions. We measured the pore size and printing time of the scaffolds. We have confirmed that the printing precision is greater than 99% and the printing time is decreased by half. The suggested solutions proved its validity through experiments and showed satisfactory results.

In this paper, we have studied the deformation problem of the scaffold caused by the FDM type 3D printer. The DOE (Design of experiment) and 3SC was used to solve the deformation problem of the scaffold generated from the adhesion surface between the scaffold and the bed. The methodology was used to derive the solution and the experiment was conducted on the derived solution. As a result of evaluating the experimental results obtained for the solution, it was found that the deformation of the scaffold was much improved. By using the DOE, We were possible to derive the output condition of scaffold.

다음과 같은 결론을 얻었다. (1) 설문 응답자의 졸업년도, 학위, 담당업무별 분포조사로부터 연 구개발 및 설계업무 분야의 젊은 실무자급 의견이 대폭 수렴되고 있음을 알 수 있으며 최근 10 년간의 국내 기계공학교육에 대한 의견이 많이 반영되고 있다고 볼 수 있다. (2) 현 대학교육은 기초지식교육에 중점을 두고 있으며 이의 현장 활용도는 긍정적으로 받아들여지고 있으나 전 문지식교육을 위한 교육수준 향상이 요구되고 있다. 특히 실무현장에서 요청되는 메카트로닉스 및 생산관련 과목의 보강이 필요하며 졸업논문 및 설계의 실질적 운용과 재학중 현장실습의 효 율성 등이 재검토되어야겠다. (3) 이러한 요구를 수용하기 위해서는 교수, 시설, 실험실습 교 육의 확충을 위한 대학예산의 증가, 졸업학점제 등으로 대표되는 획일적 교육 행정의 개선, 신 기술 지식 및 현장응용성이 강한 응용과목 도입에 의한 교육내용의 보완, 프로젝트 과제화 및 세미나식 교육 등을 통한 교육방법의 재고 등이 선행되어야 한다. (4) 대학이 담당할 계속교육 및 산학협동의 요구가 증대되고 있는 실정이며 이를 위해서는 특정분야를 중심으로 한 실용성 높은 산학협동강좌의 적극적 개설 및 기업프로젝트 참여 등을 통한 현장문제 교육, 교육, 분석, 평가, 종보교환 등의 협의가 필요하며 대학의 산업체에 대한 적극적 관심과 산학협동을 위한 제도적 장치가 마련되어야겠다.

LPWA is a cost-effective and time-saving technology with wide coverage. However, the LPWA is an ISM band that uses UHF radio waves, and its performance is very poor indoors because of its strong linearity. But, because of the possibility of achieving high performance compared to other communication in the room, this paper has studied the indoor communication performance by applying LoRa in LPWA technologies. After installing the data receiving module on the 4th floor, the transmission module was placed at the end of the building from the same floor to the 1st floor, and the data was collected. As a results, it installed on the 1st floor can be collected data with 98 ~ 99% probability, and the lowest RSSI is about -116dBm. Thus, considering the specification of LoRa with a maximum reception sensitivity -136dBm when the spreading factor is 12, the application of LPWA in the industrial field can be fully considered.

The conventional paper retrieval is the keyword-based search and as a huge amount of data be published, this search becomes more difficult in retrieving information that user want to find. In order to search for information to the user's intent, we need to introduce semantic Web that represents semantics of Web document resources on the Internet environment as ontology and enables the computer to understand this ontology. Therefore, we describe a paper retrieval system through OWL(Ontology Web Language) ontology-based reason in this paper. We build the paper ontology based on OWL which is new popular ontology language for semantic Web and represent the correlation among diverse paper properties as the DL(description logic) query, and then this system infers the correct results from the paper ontology by using the DL query and makes it possible to retrieve information intelligently. Finally, we compared our experimental result with the conventional retrieval.
