웹 기반 토론 학습은 학습자들을 능동적이고 적극적으로 학습에 참여시킬 수 있으며, 학습자 중심의 활발한 상호작용과 학습 환경을 제공한다. 그러나 기존의 웹 기반 토론 학습을 살펴보면 게시판이나 자료실을 이용한 의사 교환 기능 위주의 학습 환경 조성과 토론 학습의 실태 조사 및 활성화 방안 중심의 연구가 많고, 동적인 토론 과정을 체계적으로 지원하는 시스템은 적은 편이다. 그리고 다양한 웹 기반 수업에서 토론은 부분적으로 혹은 전면적으로 학습자의 활동으로 등장하기는 하지만, 특정한 토론 수업 모형은 개발되어 있지 않은 실정이다. 따라서 대인간 상호작용을 활성화시키고, 토론 수업 모형의 단계와 구성 요소를 구체화한 체계적인 웹 기반 토론 학습 시스템을 개발할 필요성이 있다. 본 연구는 동적인 토론 학습 활동이 이루어질 수 있도록 지원하고, 토론의 단계를 구체적으로 제시한 Hill의 일반적인 토론 학습 모형을 적용하여 체계적인 웹 기반 토론 학습 시스템을 개발하고자 한다.

This paper deals with the implementation of a robust multivariable controller using DSP board and the application to real systems. The LQG/LTR (Linear Quadratic Gaussian with Loop Transfer Recovery) controller proposed by Doyle et al.[1,2] is adopted to design the control system. A helicopter propeller setup is taken as the controlled system in the current paper, and the mathematical model is derived to design the multivariable controller. The performance of the controller is evaluated via simulations, and implementation and application to the MIMO system shows that the control performances are satisfactory and superior to those of the PID controller.

Purpose: The purpose of this study is to evaluate how university hospital Institutional Review Boards (IRBs) in Korea classify risk when reviewing clinical trial protocols. Methods: IRB experts (IRB chairman, vice chairman, IRB administrator) in the university hospitals obtaining a Human research protection program (HRPP) or IRB accreditation in Korea were asked to fill out the Google Survey from September 1, 2020 to October 10, 2020. Result: Among the 23 responder hospitals, 8 were accredited by the American Association for Human Research Protection Program (AAHRPP) and 8 were accredited by the HRPP of Ministry of Food and Drug Safety (MFDS). Seven were accredited by Forum for Ethical Review Committees in Asia and the Western Pacific or Korea National Institution for Bioethics Policy. Thirteen of 23 hospitals (56.5%) had 4 levels (less than minimal, low, moderate, high risk), 4 hospitals had 3 levels (less than, slightly over, over than minimal risk), 1 hospital had 5 levels (4 levels plus required data safety monitoring board), and 1 hospital had 2 levels (less than, over than minimal risk) risk classification system. Thirteen of 23 hospitals (56.5%) had difficulty classifying the risk levels of research protocols. Fourteen hospitals (60.9%) responded that different standards among hospitals for risk level determination associated with clinical trials will affect the subject protection. Six hospitals (26.1%) responded that it will not. Three hospitals (13.0%) responded that it will affect the beginning of the clinical trial. To resolve differences in standards between hospitals, 14 hospitals (60.9%) responded that either the Korean Association of IRB or MFDS needs to provide a guideline for risk level determination in clinical trials: 5 hospitals (21.7%) responded education for IRB members and researchers is needed; 3 hospitals (13.0%) responded that difference among institutions needs to be acknowledged; and 1 hospital (4.3%) responded that there needs to be communication among IRB, investigator, and sponsor. Conclusion: After conducting a nationwide survey on how IRB in university hospital determines risk during review of clinical trials, it is reasonable to use 4-level risk classification (less than minimal, low, moderate, high risk); the most utilized method among hospitals. Moreover, personal information and conflict of interest associated with clinical trials have to be considered when reviewing clinical trial protocols.

A SMT mounter is a kind of equipment that mounts SMD parts quickly on the printed circuit board. By using linear motors, it is controlled with high speed and precision, which is similar to semi-conductor and display process equipment. It is necessarily used in an assembly process of an electronic device. Mobile devices such as a mobile phone and PDA are required to reduce mount areas due to the demands for high performance and small size. Hence, super small sized and complex mobile devices have been developed. To improve the productivity of the corresponding equipment, designs with large sized, high speed, and multidisciplinary functions have been consistently performed. Meanwhile, a design trend of large size and light-weight on SMT mounter causes a low natural frequency of systems and vibration problems at the high speed operation. In this paper, the dynamic characteristics of the SMD mounter system were investigated through a modal test and transmissibility test, and verified by finite element method. Also, various design improvement was performed to avoid the resonance phenomena.

The purpose of this research is to analyze ‘consumer education system in middle school’, whether it is suitably organized to help students make the right decision in their daily life as a rational consumer in this fast changing “the Informational Society”. We divided the consumer education of “the Informational Society” into 4 fields of studies(consumer information technique, decision making on purchasing, consumer financial management, and consumerism) and made specific analysis for this research. The “Technology & Home Economics” textbook which follows ‘The 7th curriculum’ conducted by “Korean Educational Board” Ministry of Education & Human Resources Development for first and second grade in middle school were used for this analysis. The results founded are as follows: first, for the curriculum analysis according to the 4 fields of consumer education, both the first and the second grade students' textbook had consumer information technique as the major portion of the consumer education. Second, as a result of the comparison between the two grade levels showed that the second grade level has higher portion of consumer education in “Home economics & Technology” textbook than the first grade level. Third, the present status of consumer education showed that the first grade level's consumer education was only limited in consumer information technique, but the second grade level's consumer education was ranging evenly throughout the 3 fields of consumer education: consumer information technique, decision making on purchasing and consumerism. These results of this study contribute to the development of an efficient and desirable curriculum for the adolescent' consumer education, specially for school consumer education, in “the Informational Society”.

The quantitative expansion of nursing schools has necessitated the qualitative improvement of nursing education, which requires the development of nursing education for clinical practice. To identify strategies for strengthening the educational capacity of clinical fields and nursing schools, this study first examined the current status of nursing education for clinical practice, and then proposed several prospective directions for education. Nursing clinical practice-related studies from several Korean and international electronic databases were reviewed. Insufficient training hospitals and lack of qualified clinical training instructors were the main problems found within nursing educational resources for clinical practice, while the simple practice contents based on observation and inadequate evaluations were the main problems found in nursing educational management for clinical practice. This study suggests better standards and educational accountability for training hospitals and programs to nurture human resources for clinical practice, as well as a variety of training methods to integrate practical training courses and the expansion of formation evaluation. Based on these results, it is necessary to establish governance for nursing education for clinical practice and clarify the role and standards of each practitioner, strengthen the educational role of the hospital, and improve the system. In addition, introducing various types of education methods and strengthening evaluation standards are needed in order to enhance nursing education for clinical practice.

This study aims at comparison and analyzing of marine officer license system for fishing vessels between South Korea and New Zealand. It is urgently required to establish Republic of Korea-New Zealand mutual certification system for marine officers who are on board ships within applicable area given that New Zealand will force foreign fishing vessels within New Zealand area to reflag from 2016 in accordance with the amendment of Fisheries Act. Secondly, to compare and analyze systems between two countries will contribute to the preparatory work related to ratification STCW-F convention as New Zealand already have completed law amendment to adapt the convention. Maritime law of New Zealand, Seafarers Act and Ship Personnel Act of Republic of Korea were compared and analyzed as references. The result showed that an improvement to corresponding level to the international convention and development of safety training by vessel type, and job descriptions according to the license class are needed to Republic of Korea system. Furthermore, it is suggested to prepare specialized training for deckhands as required in STCW-F convention and standard fishing vessel officer training record for designated institute of education. Therefore institutional complementarity and framework is required as it is expected that the nations of fishing in piscary demand to reflag Korean deep-sea fishing vessels or to ratify the STCW-F convention.
