유비쿼터스 컴퓨팅 기술과 로봇 기술의 발달과 함께 지능형 로봇은 여러 분야에서 활용되고 있고, 점차 그 범위가 확대될 것으로 예견된다. 많은 서비스 로봇들 중에서 교육용 로봇을 이용한 r-Learning의 개념과 함께 다양한 필드 스터디가 이루어지고 있다. 현재 교사 보조 로봇은 곧 실용화를 앞두고 많은 HRI 연구가 요구되는데, 본 연구에서는 로봇의 교수 스타일에 따라 학생의 반응을 살펴보고자 하였다. 이를 위하여 초등학교 6학년 평균키의 양팔이 달린 교사보조 로봇 프로토 타입을 제작하고, 동일한 영어단원에 대하여 두 가지 교수 스타일(명랑, 진지)의 컨텐츠를 개발하여 탑재한 후 초등학생 3학년을 대상으로 흥미도, 성취도, 집중도가 어떻게 다른지를 실험 비교하였다. 실험 결과, 학생의 흥미도는 명랑한 로봇과 함께 수업한 집단이 높았지만, 성취도는 로봇의 스타일과 유의미한 관계가 없었으며, 집중도는 진지한 교수 스타일의 로봇과 함께한 그룹의 시간이 길었다. 이러한 결과는 교사보조 로봇의 컨텐츠를 제작함에 있어, 중요한 가이드라인이 될 것이다.

The Family Planning Program has teen intensively implemented in Korea by the national policy since 1962. However, the desired effective results were not fully obtained by many reasons such as the shortage of qualified workers, lack of eligible women's cooperation and understanding of the importance of family planning etc., The field family planning workers is classified into two categories along the governmental personnel order; the senior field worker and the assistant field worker. The former is qualified licensed nurse and the latter same as the former of a certified nurses-aid. These family planning worker's roles are somewhat in change not only in field education, distribution of contraceptions, administrating mother's class of assistant field workers but also responsible for the senior field workers such as recording, reporting and keeping statistics. Therefor, the desired success of family planning programming in Korea depends on family planning worker's professional abilities and activities in the field. In aiming to study on professional knowledge of the above two kinds of family planning workers, the following results were obtained through a field survey with question airs done as of October, 1970 in Kyonggi-Do. 1. Working term of the family planning workers in average were less than two years. The younger the assistant Field workers were, the earlier they left job. 2. The assistant field workers selected their job in order to the superficial rather than implementing job itself. 3. Most of the workers either in the health center or in the Up-Myun had a better understanding concerning with their job ; contraceptive methods, maintenance of equipment and drug keeping, and other administrative procedures, etc., 4. They had relatively better understanding and sufficient knowledge about contraception itself and application of it's methods and side effects in detail too, but less knowledges for the care after. 5. It was hard to Find out any differences in administrative knowledge and demographic understanding. 5. It is fully agreed upon that the longer the worker have experienced with the program, the more skilful she applied. 7. The worker who had training whether pre-service or insertive are working more effectively than the untrained. 8. The fundamental demographic knowledge is recommended to obtain for the workers in Kyonggi-Do.

본 연구는 교원양성기관 프로그램에서 교육실습이 아닌 형태의 현장실습을 포함한 수업을 통한 중등예비수학교사의 반성과 그 변화에 대해 살펴보는 것이 목적이다. 이를 위해 정규 수학수업에서 학습보조교사 활동을 한 중등예비수학교사 2인을 대상으로 사례연구를 진행하였다. 2015년도 1학기 수업에 참여한 중등예비수학교사들의 학습보조교사 활동 보고서 및 간담회 등의 자료를 통해 반성내용을 분석하였다. 연구 결과 학습보조교사 활동을 한 중등예비수학교사의 반성내용은 교사, 학생, 교과내용, 자기 자신 순으로 많은 것으로 나타났고 시간이 지남에 따라 학생에 대한 반성이 증가하는 것을 확인하였다. 또한 중등예비수학교사가 참여한 수업의 형태에 따라 반성내용의 비율도 달라짐을 확인하였다.

Supersonic coaxial jets are investigated numerically by using the axisymmetric, Wavier-Stokes equations which are solved using a fully implicit finite volume method. Three different kinds of coaxial nozzles are employed to understand the flow physics involved in the supersonic coaxial jets. Two convergent-divergent supersonic nozzles are designed to have the same Mach number 2.0, and used to compare the coaxial jet flows with those discharging from one constant-area nozzle. The impingement angle of the annular jets are varied. The primary pressure ratio is changed in the range from 2.0 to 10.0 and the assistant jet ratio from 1.0 to 3.0. The results obtained show that the fluctuations of the total pressure and Mach number along the jet axis are much higher in the constant-area nozzle than those in the convergent-divergent nozzles, and the constant-area nozzle lead to higher total pressure losses, compared with the convergent-divergent nozzles. The assistant jets from the annular nozzle affect the coaxial jet flows within the distance less than about ten times the nozzle throat diameter, but beyond it the coaxial jet is conical with self-similar velocity profiles. Increasing both the primary jet pressure ratio and the assistant jet pressure ratio produces a longer coaxial jet core.

Purpose: The purpose of this study was to, present basic data on the necessity of introducing assistant staff to support administrative tasks related to patient safety. Methods: This was a cross-sectional study. The participants (n=103) of this study were nurses, working at general and long-term care hospitals in Korea. Data were collected using structured questionnaires on August 29, 2019 and analyzed with SPSS 25.0. Specifically, data analysis was conducted using frequencies, mean and standard deviation, independent t-test, and X²-test. Results: Assistant staff was needed to support patient safety tasks, but this required nurses who could fully perform patient safety tasks by supplementing their work experience rather than employees who only support administrative tasks. This is because the hospital's patient safety management activities are difficult to distinguish between administrative tasks and patient safety tasks, and even nurses with five years of work experience, must be aware of the basic concepts and should have knowledge of patient safety and have gained experience in managing the patient safety activities. Conclusion: Hospitals are calling for an improvement in the system that increases the number of workers in charge of patient safety affairs and lowers their work experience, rather than the introduction of assistant staff who help with patient safety work.

이 연구에서는 A교육대학교 교육실습 중 수행되고 있는 소프트웨어교육의 현황과 제한점을 분석하였으며, 이를 해결하기 위해 기술지원 보조교사 인력을 투입하여 운영하였다. 운영 과정 중에 해당 실습 학교 담당 교사와 기술지원 보조교사를 대상으로 한 인터뷰를 진행하였다. 실습학교 교사의 만족도는 높았으며, 지속적으로 지원이 되기를 원하였다. 또한 보조교사의 역량 강화와 인력풀의 구축을 요구했다. 한편 보조교사는 팀티칭의 역할 분담을 명확하게 하고, 활동의 가이드가 제시되었으면 좋겠다는 의견을 제시했다. 이 연구를 통해 논의된 기술지원 보조교사 투입제도는 각 대학의 실습 제도와 상이할 수 있어 일반화에는 제한이 따를 수 있다. 따라서 향후 효율적인 실행 방법이 공유되어 소프트웨어교육이 활성화 될 수 있기를 기대한다.

본 논문에서는$CO_2$를 발생시키지 않고 물로부터 직접 수소를 제조하기 위하여 비열플라즈마를 이용하였다. 다중침-평판형(Multineedle-plate electrode geometry reacto: MPER)과 단일침-평판형(Needle-plate electrode geometry reactor: NPER) 두종류의 수소제조 반응기를 설계 제작하여 수소 발생에 미치는 영향에 대하여 실험하였다. 수소발생을 높이기 위해서는 강한 아크성 스트리머 방전 발생과 효과적인 수표면 방전을 위한 수표면 조건을 고려해야만 된다.

This paper describes the development of a 3-DOF laparoscopic assistant robot system with motor-controlled bending and zooming mechanisms using the voice command motion control and auto-tracking control. The system is designed with two major criteria: safety and adaptability. To satisfy the safety criteria we designed the robot with optimized range of motion. For adaptability, the robot is designed with compact size to minimize interference with the staffs in the operating room. The required external motions were replaced by the bending mechanism within the abdomen using flexible laparoscope. The zooming of the robot is achieved through in and out motion at the port where the laparoscope is inserted. The robot is attachable to the bedside using a conventional laparoscope holder with multiple DOF joints and is compact enough for hand-carry. The voice-controlled command input and auto-tracking control is expected to enhance the overall performance of the system while reducing the control load imposed on the surgeon during a laparoscopic surgery. The proposed system is expected to have sufficient safety features and an easy-to-use interface to enhance the overall performance of current laparoscopy.
