The purpose of this study was to classify subjective structure of observation experience toward delivery on nursing students. A Q-methodological approach that gives information about the way of analyzing the subjectivity of each item was used. Q population was performed for analyzing through interview and literature review. From this, ultimately, a final Q sample of 35 statements was obtained. The P sample sorted the Q sample for observation experience toward delivery. The collected data was analyzing using PC QUANL program, which revealed three distinctive types of delivery experience about nursing students. Type 1 is a sympathy towards delivery woman, type 2 is a requirement of care. And type 3 is a future of analogical inference of delivery type. In conclusion, it is needed not only to give high quality of nursing service but also to have a right job value based on proper understanding of patient. Also, it is recommended about education of nursing students for making right view of value based on the three types of delivery experience.

Concentration is one of the most important factor in learning ability. It is important to improve concentration for learning ability. Most digital kids have been accustomed to addictive media like games since childhood, so traditional methods of teaching and learning has been difficult to give interests for them. Therefore introducing a new teaching methods was inevitable for students with low concentration. This is an experiment to prove the hypothesis that the concentration training by certain serious game would be helpful for improving students' concentration. Not only some serious games but also meditation by music was effective to improve concentration in the experiment. Average people is hard to immerge in meditation. but some serious games involve fun factors like curiosity, challenges, competitions and rewards. Games are not more negative to young people, will be helpful to society in various forms.

With the development of information and communication technology, the possibility of utilizing 3D virtual reality in education has been sought. Especially, the screen composition in the virtual reality has the possibility of inducing the emotion of the user which may affect the learning. However, there is little research on what aspects of the screen can cause emotions. The purpose of this study is to analyze the user's perception of screen components inducing emotion in virtual reality learning environment. Using Multi Dimensional Scaling (MDS), the user's perception of the main screen in a representative virtual reality learning environment platform was investigated. As a result, the dimension of depth on the screen and the dynamics of the avatar related to the movement were confirmed. This study is meaningful to explore technical variables that can induce emotions among screen elements in virtual reality contents.

In this paper new air-cooling system utilizing Stirling engine was proposed for improving efficiency in solar photovoltaic power generation. The solar cell plate was equipped with semi-circular channel for air flow on the backside. Beta-type Stirling engine was installed on the plate and its flywheel was connected to a motor fan by a transmission belt. A forced convective air flow for heat radiation was generated by the operation of the self-starting Stirling engine. The performance tests for power generation of solar cell with or without the proposed air-cooling system were conducted under halogen lamp. From the experimental results, it was found that decline in output voltage of the solar cell with proposed cooling system was 25% less than that of the solar cell without cooling system.

Hopkins의 도약률(Sprung Rhythm)은 영어의 운율자질인 강세에 의한 엄격한 정형률을 고수하고 있다. 즉 약강 5보격이나 약강 6보격의 정형률을 지킨다고 Hopkins는 주장한다. 일반 독자나 운율비평가는 이를 인정한다. 문제는 시인의 음량(quantity) 기준에 의하여 강, 약 자리를 어떻게 충족시키고 있느냐 하는 점이다. 모든 비평가는 Hopkins의 음량 기준의 지나친 편의성과 임의성, 및 응통성?에 대하여 그의 음량 이론을 수용하려하지 않는다. 그러나 Kiparsky는 Hopkins의 설명에 따라 시인의 도약률을 분석하면 시인의 음량 이론이 이유 있음을 설명해 보인다. Kiparsky의 분석에서 문제점은 없는가? 만약 있다면 그것은 바로 Hopkins의 음량이론의 문제점이 될 것이다. 이 연구에서는 Hopkins의 편지 속의 설명은 실제로 독자의 낭송 속에서 어떻게 실현될 것인가 즉 '귀로 듣고 감상(ear and taste)'할 때 나타날 리듬형, 즉 낭송의 틀에 의한 분석을 시도하였다. 그것은 도약률이야 말로 읽히기 위한 것이며 '보는 시'가 아니라는 전제에서이다. 여기에서는 낭송에서 나타날 도약률의 음량과 장단, 즉 지속시간을 하나의 '낭송보(Textsetting for Sprung Rhythm)'에서 투사해 보고자 했다. 그 낭송보는 Hayes & Kan(1994)의 '어린이의 민속노래 보(Textsetting for Children's Folk Songs)'를 원용하였다. 약강 4,5,6보격, 강약 4,5,6보격의 일정한 강세 모습과 일정한 지속시간을 보여주는 도약률의 '낭송보'는 다음과 같다('약'자리와 '강'자리의 간격은 일정하게 보고 '강'의 돋들림은 격자로 더 높게 표시하였다). 이와 같은 낭송보는 독자, 즉 낭송자의 낭송 가능 범위를 그려 준다. 즉 약자리의 두개나 그 이상의 음절을 한꺼번에 낭송할 수 있음을 보여 준다. 그 음은 자연히 연음(slurring)이 되기 마련이다. 그러므로 이 연구는 다음과 같은 사실을 규명해 준다. 첫째, 어떤 시행도 규칙적인 박으로 낭송된다. 둘째, 음량은 박자에 의하여 좌우된다. 즉 강과 약자리의 일정한 지속시간의 범위 내에서는 몇 개의 음절도 낭송이 가능하다. 그것은 일정한 간격의 자리를 나타내는 격자로 결정된다. 따라서 모라(morae)의 개념보다도 박자의 개념으로 도약률은 낭송된다. 셋째, 모든 약자리와 강자리는 일정한 간격과 실제의 박(묵박도 포함)에 의하여 규칙적이다. 넷째, 외율음보는 격자의 길이내에서 낭송된다. 그러나 이 연구의 기본은 시인과 독자의 율형(Metrical Pattern)에 대한 의식과 의도(intention)가 전제된다. 이것은 이 연구의 문제임과 동시에 장점이다. 시율의 분석은 보는 율형이 아니라 읽고 낭송하는 율형으로 분석되어야 함을 보여 준 것이 이 연구의 기여이다.

YBCO 초전도 박막을 제조하기 위해 일반적으로 사용되는 RABiTS공정을 통해 제조된 양축 정렬된 Ni 선재 위에 직접 YBCO를 증착시키려는 시도가 많이 이루어졌다. Ni 위에 직접 증착시킨 YBCO 박막은 c-축으로 정렬되는 온도에서 Ni이 확산되어 YBCO와 반응하여 초전도 물성을 약화시킨다. 이것을 방지하기 위하여 완층층을 먼저 증착을 하는 연구를 시행하였다. 본 연구는 Ni-5at.%W(100) 기판위에 hot-wall type MOCVD (metal organic chemical vapor deposition)를 이용하여 증착을 실시하였다. 완층층으로는 Ni, YBCO와 각각 4.70%, 3.32%의 lattice mismatch를 갖는 $Yb_2O_3$를 선택하였으며, 증착 조건으로는 온도 $800\;{\sim}\;1000^{\circ}C$, 시간 3 ~ 10min, 증착압력 10 Torr의 조건에서 증착을 행하였다. $Yb_2O_3$를 형성하기 위해 산소를 이용하였으나 $Yb_2O_3$(200) 형성을 방해하는 NiO(111)이 형성되었다. 산소를 대신해 수증기를 이용하여 NiO 상이 없는 $Yb_2O_3$(200)을 형성하였다. 증착 시간과 수증기 압력에 따른 $Yb_2O_3$의 $I_{(200)}/(I_{(111)}+I_{(200)})$의 상대 회절강도비를 XRD (X-ray diffraction)를 이용하였고, 증착된 표면 형상은 SEM(scanning electron microscopy)을 통해 관찰하였다.

In order to shoot underwater, the photographer must be equipped with shooting equipment and enter into the water. Since the photographer directly enters the water, safety accidents occur frequently due to various obstacles or deep water in the water. The proposed underwater stereo photography technique can solve the safety accident problem caused by the entry of the photographer into the water by using the drone for underwater photographing. In addition, this technique has the advantage of obtaining underwater images at low cost. In this study, the angle of the proposed cam for stereoscopic photography was analyzed and the condition that the proper stereoscopic image can be viewed was defined as the distance from the floor of 18cm to the floor distance of 41.4cm. This provision is proposed to be used to adjust the height of the shooting area descended by the elevation chain of the water surface hovering drones.

This study was aimed to grasp online learning quality satisfaction in Dental Hygiene students. A survey was conducted targeting finally 228 dental hygiene students at a university in Gangwon Province from February 3, 2021 to February 17. As a result of analysis, the online class satisfaction by good instruction component was lower overall than importance. The learning environment satisfaction was lower than its importance. A difference between importance and satisfaction with online learning by detailed good instruction component showed a relatively big difference in systematic class, online learning environment, ability to convey the class contents. The need for online learning content was high in teaching material and VOD. The class operation type satisfaction was high in a non-real time class. Accordingly, a continuous effort is conceivably necessary for improving quality given the teaching-design establishment of online learning.
