본 연구는 코로나-19 상황에서 간호대학생의 임상실습을 대체하는 혼합실습 경험의 본질을 파악하기 위해 시도되었다. 2020년 12월 17일부터 2020년 12월 31일까지 간호대학생 8명을 대상으로 심층 인터뷰를 개별적으로 시행하여 자료 수집을 하였고 Colaizzi의 현상학적 분석 방법론을 적용하여 자료를 분석하였다. 간호대학생의 혼합실습 경험을 통해 '불안 속 수용하기', '전면에 드러난 자율성', '마음을 졸인 비대면 실습', '지식 채워나가기', '목표달성이 가능한 다양한 접근', '아쉬움이 남은 최선의 실습'의 6가지 범주가 나타났다. 감염병 대유행 상황에서 간호대학생은 혼합실습에 대한 불안과 우려를 가지고 임상실습 대체를 받아들였으며, 자기주도적인 학습을 통해 실습 적응 방법을 모색하고 임상실습의 목표를 달성하는 경험을 하였다.

We intend to illustrate how contemporary architects have conceptualized spaces with words. Language practice is so much important work for the contemporary architects as designing realistic building (material practice) As this point of view we need to interest in theses of architects which contains their unique ideas an characters. The purpose of this study is for understanding how contemporary japanese architects embody through special conception when day design the mixed wooden construction and for looking for the possibility of the development of it. As a result the mixed wooden construction candy understood as an expression form how an architects things about relationship between parts and parts, parts and the whole and the character of materials that consist it and such relationship is determined by the requirement of space.

Purpose: This study used an exploratory sequential approach (mixed methods) design to explore essential meaning through comparing and analyzing the experiences of nursing students in virtual simulation practice and high fidelity simulation practice education in parallel. Methods: The study participants were 20 nursing students, and data were collected through focus group meetings from July 17 to August 5, 2020, and via online quantitative data from November 10 to November 15, 2020. The qualitative data were analyzed using Giorgi's phenomenological method, and the quantitative data were analyzed using descriptive statistics, the Mann-Whitney U test, Kruskal-Wallis H test analysis of variance and Spearman's ρ correlation. Results: The comparison between the two simulation training experiences was shown in five contextual structures, as follows: (1) reflection of the clinical field, (2) thinking theorem vs. thinking expansion, (3) individual-centered learning vs. team-centered learning, (4) attitudes toward participating in practical training, (5) metacognition of personal competency as a prospective nurse, and (6) revisiting the method of practice training. There was a positive correlation between satisfaction with the practice and the clinical judgment ability of high fidelity simulation, which was statistically significant (r=.47, p=.036). Conclusion: Comparing the experiences between virtual simulation practice training and high fidelity simulation practice training, which has increased in demand due to the Coronavirus Disease-2019 pandemic, is meaningful as it provides practical data for introspection and reflection on in-campus clinical education.

The model using homogenization technique based on energy concept for the prediction of the failure criterion of staple fiber mixed soil was developed to increase the practice and the application of staple fiber as a reinforcement for improving soft ground and agrictural structures. Parameters of the model are aspect ration and volumetric ocntnet of fiber, cohesion and internal friction angle of soil, adhesiion intercept of soil and fiber. It is judged that the model developed in this study is applicable to the soil composed of clay, silt and sand mixed by linear types of fiber such as steel bar, steel fiber , natural fiber etc..

The model using homogenization technique based on energy concept for the prediction of the failure criterion of staple fiber mixed soil was developed to increase the practice and the application of staple fiber as a reinforcement for improving soft ground. Parameters of the model are aspect ratio and volumetric content of fiber, cohesion and internal friction angle of soil, adhesion intercept and interface friction angle of soil and fiber. It is considered that the model developed in this study is applicable to the soil composed of clay, silt and sand mixed by thread types of fiber such as steel bar, steel fiber, natural fiber etc.

Background: This study investigated the prevalence and associated factors of musculoskeletal pain among professional dancers who experienced a lapse in group practice due to coronavirus disease 2019. Methods: General characteristics, practice time, region of musculoskeletal pain due to injury using the visual numeric scale (VNS), and causative motion were surveyed among professional dancers. Pain of VNS 0 to 3 was categorized as "no or minor," 4 to 6 was categorized as "moderate," and 7 to 10 was categorized as "severe." The causal motions of musculoskeletal pain were analyzed according to body region. Factors other than motion associated with pain were also analyzed. Results: In total, 368 participants were included. In the univariate analysis, age and practice time were positively associated with "moderate" pain. Practice time, dance experience, and postural accuracy were positively associated with "severe" pain, as was performing Korean traditional dance. In the multivariable analysis, practice time, group practice, and age were positively associated with pain of VNS 4 to 10, and practice time, group practice, and Korean traditional dance were positively associated with pain of VNS 7 to 10. Conclusion: Among the factors related to dancer training, practice time, group practice, and dance type affect the occurrence of pain.

본 연구의 목적은 임의효과(random effect)를 포함하는 혼합모형(mixed model)을 이용하여 흉고직경과 수고의 변화량을 평가하는데 있다. 강원도 굴참나무 임분을 대상으로 흉고직경과 수고를 조사하고 3년 후 동일 임분을 재조사하였다. 혼합모형에서 굴참나무의 흉고직경-수고 관계는 고정효과(fixed effect)이고 초기측정과 반복측정의 흉고직경과 수고 차이를 임의효과로 설정하였다. 임의효과에 따른 모형의 적합도를 검정하기 위하여 아카이케의 정보기준(akaike information criterion, AIC)을 참고하고 반복 측정에 따른 분산-공분산 행렬과 오차항을 산정하였다. 추정된 공분산은 -0.0291이고 오차항은 0.1007을 나타내었다. 분산-공분산 행렬을 이용한 임의효과가 포함된 모형의 AIC(=-215.5)는 고정효과를 고려한 모형의 AIC(=-154.4)에 비해 낮은 수치를 나타내었다. 이러한 결과는 범주형 자료의 임의효과가 모형 개발에 반영되는 결과인 것으로 조사되었다. 그러므로, 본 연구에서 적용된 혼합모형은 반복 측정 자료를 이용한 모형 개발에 활용이 가능한 것으로 판단된다.

Reliability demonstration tests (RDT's) are widely employed in design verification and process validation stages of industry. New mixed attribute-variable RDT plans that compromise demerits of the corresponding zero and zero or one failure plans which are common in practice are developed for the exponential distribution. The proposed mixed plans are compared with the typical RDT plans in terms of probability of acceptance and expected test termination time. A numerical example is provided to illustrate the mixed plans and a procedure to extend these plans to the Weibull distribution with known shape parameter is also presented.

Based on the theory of space perception, this paper concludes that the mixed reality application under the theory of space perception has a three-level definition of visual hierarchy and then analyzes the component elements of interface design and the classification mode of interface windows. Next, carry out case practice research through this theoretical definition, and finally conduct the survey and analysis of questionnaire data, verifying that the mixed reality interface design based on spatial perception theory meets the user experience elements of Usability, Availability, and Attraction. The conclusion is that the constituent elements of interface design and the window classification mode can provide specific and practical design specifications for mixed reality interface design, reduce the interaction cost of completing tasks, reduce users' cognitive load, and make it easier for users to receive interface information

The usage of mixed 2D and 3D CAD data of commercial CAD systems is required in the construction practice. Sometimes 3D wireframe model is required by end-users when 2D CAD data is delivered. However, current KOSDIC can not represent 3D CAD data, because it has been developed as a 2D drawing delivery standard. Therefore, this study is to provide exchange and sharing of mixed 2D and 3D CAD data that add 3D wireframe model in the KOSDIC. To achieve this purpose, the authors have investigated the 3D CAD entities of commercial CAD systems, and have analyzed STEP standards providing 3D wireframe model. The result, the authors have extracted 3D CAD common entities based wireframe model which shall be added in the KOSDIC. This study can be beneficial by using the developed data model for heterogeneous CAD systems, and by providing the representation of mixed 2D and 3D CAD data in construction practice such as GIS, piping system, and so forth.
