This study was conducted to investigate academic self-efficacy, learning motivation, and self-directed learning which influence problem-solving ability in nursing students. A total of 217 third year students were recruited from two nursing colleges in Gwangju. Structured questionnaire was self-administered from March 2 to 31, 2012. In academic self-efficacy, there were significant differences in gender, high school type, character. Problem-solving ability showed statistically significant differences in curriculum usability after graduation. In multiple regression analysis, self-efficacy, learning motivation and self-directed learning were significant factors of problem-solving ability explaining 37.3% of the variables. In conclusion, self-efficacy, learning motivation, and self-directed learning had a positive effect on problem-solving ability in nursing students. To enhance problem-solving ability for nursing students, it is necessary to develop teaching program and curriculum for increasing academic self-efficacy, learning motivation, and self-directed learning.

코로나19로 인해 전 세계가 대 격변기에 있다. 경기 위축과 불확실성이 증대되고 있어 많은 기업과 가게 등 경제 주체들이 어려움을 겪고 있다. 이러한 상황에서 창업을 계획한다면 실패에 대한 많은 심리적 부담을 갖게 될 것이기에 더욱더 위험을 감수하고 위기를 기회로 활용하려는 창의적이고 적극적인 기업가의 태도가 필요하다. 따라서 본 연구는 기업가의 심리적 특성 변수라 할 수 있는 기업가정신과, 창업할 때 기업가가 갖고 있는 창업실패두려움 그리고, 창업자기효능감이 창업의도에 어떠한 영향을 미치는 지 알아보고자 한다. 본 연구에서는 기업가정신을 혁신성, 진취성, 위험감수성 세 가지 하위변수로 구분하였으며, 창업실패두려움도 재무적손실 두려움, 심리적손실 두려움, 경력손실 두려움으로 구분하여 각각의 하위변수들이 창업의도에 어떠한 영향을 미치는 지 알아보고자 한다. 또한 창업 상황에서 일종의 자신감이라 할 수 있는 창업자기효능감이 기업가정신과 창업의도 관계에서, 창업실패두려움과 창업의도관계에서 어떠한 매개적 역할을 하는 지 알아보고자 한다. 이를 통해 창업 분야에서 기업가정신과 창업실패두려움, 창업자기 효능감의 역할에 대한 학문적, 실무적 시사점을 도출하고자 한다.

The main purpose of this study was to develop a mobile platform that supported college students to become self-regulated learners, and to examine its effects on students' academic achievement and self-regulated learning abilities. For this purpose, a mobile platform was designed and developed through the steps of systems approach. All the sub-steps were monitored and pilot-tested. The mobile platform incorporated a number of features designed specifically for the self-regulation components, with the intention of enhancing students' academic achievement and self-regulated learning abilities. Finally, research results suggested that students were taking advantage of the mobile platform that supported students' self-regulated learning. There were statically significant differences in academic achievement according to the type of mobile platform, F(1,133)=1767.202, P<.001

High sensitivity magnetic sensor having foreign metal detection capability is proposed utilizing giant magneto-impedance effect. Strip sensor showed the increasing output voltage when the external magnetic field was applied along with strip from strip grounding point, although the initial DC voltage varied depending on the pointing direction of strip sensor. Proposed sensor was able to eliminate more than half of background noise using active noise filter to achive high sensitivity, and it showed the capability to detect magnetized foreign metal object independent of ambient electro-magnetic noise and earth magnet. In case of ferrous sphere, the metal detection up to 0.8mm diameter was experimentally demonstrated at 5mm distance from strip sensor.

Ship's auto pilot is must necessary the azimuth data, which is supported by a gyro, geomagnetism and GPS compass. The gyro compass is operation of stability & correct , therefore it is used by big size shipping because of high cost. The other side, medium and small size shipping are used the geomagnetism and GPS compass of low cost. This paper have studied that the two jobs are going on at the same time both of there's advantage. Which is asked the algorithm for stability azimuth data on reject methode the defect of respect with geomagnetism & GPS compass.

본 논문에서는 GAN 과 자기 지도 학습(self-supervised learning)을 통해 입력 얼굴 영상의 공간 해상도를 4 배 증가시키는 기법을 제안한다. 제안하는 기법은 변형된 StarGAN v2 구조의 생성자와 구분자를 사용하여 저해상도의 입력 영상만을 가지고 학습 과정을 거쳐 고해상도 영상을 복원하도록 자기 지도 학습을 수행한다. 제안하는 기법은 복원된 영상과 고해상도 영상 간의 손실을 줄이는 지도 학습이 가지고 있는 단점을 극복하고 입력 영상만을 가지고 영상 내부에 존재하는 특징을 학습하여 얼굴 영상에 대한 고해상도 영상을 복원한다. 제안하는 기법과 Bicubic 보간법과의 비교를 통해 우수성을 검증한다.

Most of light duty AGVs(AGCs) using tape of magnetic for the guide path have digital guidance magnetic sensor. Digital guidance magnetic sensor using magnet-tape is on/off type and has positioning error of magnet-tape as 10~50 mm. AGC using this sensor doesn't induce accurate position of magnet-line which is magnet-tape because of magnetic field which motor in AGC creates, outer magnetic field, earth's magnetic field, etc. AGC when driving wobbles due to this error and this error can cause path deviation. In this paper, we propose fuzzy inference system for improvement of bipolar analog magnetic guidance sensor performance. Fuzzy is suitable in term of fault tolerance, uncertainty tolerance, real-time operation, and Nonlinearity as compared with other algorithms. In previous research, we produced bipolar magnetic guidance sensor and we set the threshold in order to calculate digital values of magnet position. Fuzzy inference system is designed using outputs of Analog hall sensors. Magnet position calculated by digital method is improved by outputs of this system. In result, proposed method was verified by improving performance of magnetic guidance sensor.

Recently, ICT has emerged as an indispensable tool for teaching a variety of subjects in education systems. In this paper, we examine the effect of the instructional models for ICT on the practical ability in the application of information with relation to the levels of self-regulated learning strategies. Students were divided into 3 groups, according to the instructional model for ICT which were problem search learning, problem solution learning, and discussion learning. As an experimental tools, we did pretest using self-regulated learning strategies measurement questionnaire and did pretest and posttest using practical ability in the application of information measurement questionnaire. The results show that higher level of self-regulated teaming strategies group has high practical ability in the application of information than lower level group. Other interesting results are also provided.
