본 연구의 목적은 기초건축교육의 활성화를 위한 전문교사 교수지도방안을 제기하는 것이다. 이를 위하여 본 연구 방법은 현재 국내에서 기초건축교육이 진행되고 있는 사설기관 중 한 곳을 선정하여 활동하고 있는 예비교사들을 대상으로 설문조사를 실시하였다. 연구 결과 기초건축교사는 첫째, 일반적인 건축의 전문적 지식 전달보다 기초건축교육이 가지고 있는 그 의미와 정당성을 바탕으로 수업에 임하는 자세가 필요하고, 수업을 진행하기에 앞서 기초건축교육을 위한 선행교육이 이루어져야 한다. 둘째, 프로그램 및 교수학습지도안은 교사들에게 맞도록 개선 또는 개발되어야 한다. 그리고 셋째, 기초건축교사는 건축 관련 지식뿐만 아니라 교육자로서의 지식과 자세가 요구된다. 마지막으로 향후 기초건축교사 양성을 위하여 기초건축교육의 프로그램 수정·보완 및 지속적인 연구가 필요할 것으로 판단된다. The purpose of this study is to give fundamental date to train professional teacher for the basic architectural education. For this study on the basic architectural education, the domestic literature review is conducted for action plan of basic architectural education. Foreign case studies, educational programs and textbook content development for basic architectural education were analyzed. In addition, this study through literature review, interviews and observation for training professional teacher were conducted. The methods of this study were to select one of the private institutions for the basic architectural education in the country and to survey for teaching learning scenario, teaching learning methods, teaching learning program, mutual communication to basic architectural teacher. As a result, first, basic architectural teacher has their attitude for basic architectural education rather than technical knowledge of architecture. In addition, the study for basic architectural education is conducted. Second, teaching learning program and teaching learning methods have to be modified to fit the teachers. Third, the basic architectural teacher should have not only architecture-related knowledge but also attitude and qualification as an educator. Finally, for training good architectural teacher, modification and supplementation of architectural education program and future study should be required.

This paper reviews several issues and drawbacks on institutional care for the elderly in LTC system. Under the law and operational guidelines, people in the first class and part of the second class based on care ratings are eligible to use institutional care. Current rating procedure has, however, revealed a lack of objectivity; accessibility for institutional facilities shows huge differences by local governments and residential regions; after national exam system has introduced, front-line workers at some regions are in short supply; 20% of co-payment rate also lays a burden on the low-class elderly. Several modifications are required to improve LTC care utilization, equal access, and better outcomes.

Purpose: The purpose of this study was to identify the sequential mediating effects of social support and self-efficacy in the relationship between focusing manner and quality of life in patients with chronic pain. Methods: The participants were 192 patients with chronic pain who visited a university hospital in D city from August 25, 2020 to October 27, 2020. The collected data were analyzed using SPSS for Windows version 26.0, and mediating effects were evaluated using the PROCESS macro model 6. Results: Social support(B=0.31; 95% CI=0.15~0.51) and self-efficacy(B=0.18; 95% CI=0.07~0.30) had mediating effects on the relationship between focusing manner and quality of life. Focusing manner did not directly affect quality of life; instead, social support and self-efficacy had sequential mediating effects on the relationship between focusing manner and quality of life(B=0.05; 95% CI=0.02~0.11). Conclusion: The findings of this study indicate that social support and self-efficacy are important factors related to quality of life in patients with chronic pain. It is also expected that enhancing social support and self-efficacy can further improve quality of life among chronic pain patients.

Fly ash dumped generally pollutes environment in the world. With the aim of sustainable development, the contribution of fly ash in concrete to the mechanical properties should be investigated. Variation of the modulus of elasticity of concrete is an important factor to evaluate the performance. In this study, the experiments were carried out over water-binder ratios of 0.34 and fly ash-binder ratios from 0% to 30%. The elasticity of modulus of high performance concrete replacing fly ash were determined on 7days and 28 days.

이민지,홍주완,윤송희,임현성 대한시과학회 2023 대한시과학회지 Vol.25 No.3
목적 : 4차 산업혁명이 진행됨에 따라 타각적 굴절검사값, 수차 및 동공크기 등을 이용하여 최적의 안경처방값을 도출해주는 머신러닝(machine learning)을 개발하고자 하였다. 방법: 시력에 영향을 줄 수 있는 안질환 및 전신질환이 없고 안구 수술 이력이 없는 근시안(1,000안)을 대상으로진행하였다. I-Profilerplus(Zeiss, Berlin, Germany)를 사용하여 타각적 굴절이상도(objective-refraction) 및안구수차(ocular wavefront-aberration), 동공 크기를 측정하였고, 자각적 굴절이상도(subjective-refraction)는Visuphor500(Zeiss, Berlin, Germany)를 사용하여 구면 굴절력(S, Diopter), 원주 굴절력(C, Diopter), 난시축(Ax, °)을 측정하였다. 측정 후, 파이썬(Python, version 3.10)을 이용하여 머신러닝 모델 생성 및 예측 성능을확인하였다. 결과: 자각적 굴절이상도에서 구면 굴절력에 영향을 미치는 요인은 타각적 구면 굴절력, defocus aberration, spherical aberration, trefoil aberration 순으로 높았고, 원주 굴절력에 영향을 미치는 요인은 타각적 원주 굴절력, defocus aberration, coma aberration, trefoil aberration 순으로 높았으며, 난시 축은 타각적 난시축만영향을 미치는 것으로 나타났다. 구면 굴절력, 원주 굴절력, 난시 축의 자각적 굴절이상도와 머신러닝 예상값은차이가 없는 것으로 나타났다(p=0.976, 0.948, and 0.349, respectively). 결론 : 자각적 굴절이상도를 예측하는 머신러닝 모델을 생성하였고, 해당 모델의 예측된 값과 자각적 굴절이상도와 유의한 차이가 없는 것을 통해 예측 정확도를 확인하였으며 앞으로 개인 맞춤형 처방을 위한 정확한 안경처방값을 도출하는데 기초자료가 될 수 있을 것으로 생각된다. Purpose : As the Fourth Industrial Revolution progresses, to develop machine learning to draw subjective prescription values by using objective refraction, ocular aberrations, and pupil size. Methods : Myopic subjects (1000 eyes) with no ocular or systemic diseases that could affect vision and no history of ocular surgery were participated. I-Profilerplus (Zeiss, Berlin, Germany) was used to measure objective refraction, ocular wavefront-aberration, and pupil size. For subjective-refraction, spherical refraction (S, diopters), astigmatic refraction (C, diopters), and astigmatic axis (Ax, °) were measured using a Visuphor500 (Zeiss, Berlin, Germany). After the measurements, the machine learning model was developed using Python (version 3.10) and checked its prediction performance. Results : In the subjective refraction, the factors affecting the spherical refractive power were the highest in the order of objective spherical refractive errors, defocus aberration, spherical aberration, and trefoil aberration had the highest impact on spherical refractive power, while objective cylindrical refractive errors, defocus aberration, coma aberration, and trefoil aberration had the highest impact on cylindrical refractive power. However, the astigmatic axis was affected only by objective astigmatic axis. There was no difference between subjective refractive errors and machine learning predicted refractive errors for spherical refraction, cylindrical refraction, and astigmatic axis(p=0.976, 0.948, and 0.349, respectively). Conclusion : A machine learning model that predicts the subjective refractive errors was developed, and the prediction accuracy was confirmed through there was no significant difference between the predicted refractive errors and the subjective refractive errors. Therefore, it is thought that it can be used as basic data to derive accurate eyeglass prescription for personalized prescriptions in the future.
