Background: Supporting the elderly population is presented as a social issue, and it affects age discrimination, which forms a negative perception and avoids the elderly. Since age discrimination lowers the quality of life of the elderly and hinders social unity, it may be important to research related factors. This study examined the physical function as a factor that influences discrimination experiences and aimed to identify the relationship between physical function factors and discrimination experiences. Methods: In this study, we analyzed 20,225 elderly from the 2014 and 2017 survey of living conditions and welfare needs of Korean older persons, conducted nationwide among older than 65 years. Physical function factors are activities of daily living, instrumental activities of daily living, sight discomfort, hearing discomfort, chewing discomfort, and leg strength as factors of interest. We performed multivariable logistic regression that reflected survey characteristics, adjusting for socio-demographic factors, health related factors, and social-support factors. Results: The number of elderly who faced discrimination experiences was 1,175 (5.8%). The results showed that the odds ratio of facing a discrimination experience in the dependent group was significantly higher compared to the independent group when being transferring out of the room (4.05; 95% confidence interval [CI], 1.50–10.88) and difficulty in hearing (1.25; 95% CI, 1.05–1.49). Even with respect to chewing ability, which was significant in models 1 and 2, they face more discrimination experiences (1.30; 95% CI, 1.11–1.53). Conclusion: These research results indicate that an important strategy for preventing age discrimination is to understand the physical function conditions of the elderly and promote the physical functions of the elderly related to transferring, hearing, and chewing; it is necessary to develop a practical intervention plan that considers these aspects. Keywords: Discrimination in the elderly; Discrimination experience; Physical function; Survey of living

실생활 맥락의 문장제에 대한 중학생들의 인식 조사 연구

이규희,이지현 대한수학교육학회 2021 수학교육학연구 Vol.31 No.4

This study aims to explore how ‘sensitively’ Korean middle school students consider realistic contexts while solving problematic problems. Six pairs of word problems were collectively administered to 85 students in third grade during a mathematics lesson, and follow-up interviews were conducted with 11 students. The survey found that the proportion of students who solved the problems by sensitively considering real-world knowledge was not high (22%). In the follow-up interviews, the students reported that they would think of mathematics separately from real-world situations. An analysis of the students’ reactions to real-life problems has implications for the practice of school mathematics regarding real-life word problems. 이 연구의 목적은 우리나라 중학생들이 실생활 맥락의 문장제를 해결하는 과정에서 실생활 맥락의 지식을 얼마나 예민하게 고려하는지, 또 그렇게 인식하는 이유가 무엇인지를 탐색하는 데 있다. 본 연구에서는 85명의 중학교 3학년 학생들에게 정형화된 실생활 맥락의 문장제와 불확실성을 내포한 실생활 맥락의 문장제를 해결하게 하고, 11명의 학생들을 대상으로 후속 인터뷰를 수행하였다. 설문 조사 결과, 실생활 맥락을 예민하게 고려하여 실생활 맥락의 문장제를 해결한 학생의 비율은 약 22%로 높지 않았다. 후속 인터뷰 결과, 대부분의 학생들이 실생활 맥락의 문장제와 현실 상황을 분리하여 사고하는 특징을 나타냈다. 본 연구에서 분석한 실생활 문장제에 대한 학생들의 비현실적 반응은 학교수학에서의 실생활 문장제 교수학습 관행에 시사점을 줄 수 있을 것이다.

이규희,URTNASAN ERDENEBAYAR,황상원,이희영,이정훈,고상백,육현 연세대학교의과대학 2022 Yonsei medical journal Vol.63 No.-

Purpose: We propose the Lifelog Bigdata Platform as a sustainable digital healthcare system based on individual-centric lifelog datasets and describe the standardization of lifelog and clinical data in its full-cycle management system. Materials and Methods: The Lifelog Bigdata Platform was developed by Yonsei Wonju Health System on the cloud to support digital healthcare and precision medicine. It consists of five core components: data acquisition system, de-identification of individual information, lifelog integration, analyzer, and service. We designed a gathering system into a dedicated virtual machine to save lifelog or clinical outcomes and established standard guidelines for maintaining the quality of gathering procedures. We used standard integration keys to integrate the lifelog and clinical data. Metadata were generated from the data warehouse after loading combined or fragmented data on it. We analyzed the de-identified lifelog and clinical data using the lifelog analyzer to prevent and manage acute and chronic diseases through providing results of statistics on analysis. Results: The big data centers were built in four hospitals and seven companies for integrating lifelog and clinical data to develop the Lifelog Bigdata Platform. We integrated and loaded lifelog big data and clinical data for 3 years. In the first year, we uploaded 94 types of data on the platform with a total capacity of 221 GB. Conclusion: The Lifelog Bigdata Platform is the first to combine lifelog and clinical data. The proposed standardization guidelines can be used for future platforms to achieve a virtuous cycle structure of lifelogging big data and an industrial ecosystem.

'점'과 '선'에 관한 수학적 분석과 교과서 분석

이규희,Yi, Gyuhee 한국학교수학회 2021 韓國學校數學會論文集 Vol.24 No.1

본 연구에서는 '점'과 '선'을 '크기' 관념에 주목하여 수학적 분석을 하고, Euclid 기하의 관점에서 한국의 2015 개정 교육과정에 따른 중학교 수학 1의 기본도형 내용영역과 미국 기하(Geometry)의 교과서 서술을 비교하여 분석하였다. 첫째, '점'과 '선분'을 '크기' 관념에 주목하여 수학적으로 분석한 결과, 1) '무한소'의 인정과 배제, 2) '측도론'과 '집합론'에 따라 수학적 관점이 달라질 수 있음을 알 수 있었다. 둘째, '점'과 '선'에 관한 교과서의 서술을 Euclid 기하의 관점에서 분석한 결과, 1) 대부분의 한국의 2015 개정 교육과정에 따른 중학교 수학 1의 기본도형 내용영역에서는 '크기'가 있는 점과 선을 소개 혹은 직접 그리는 학습활동을 제시한 후, 점과 선의 '관계'를 서술하는 방식으로 전개하고 있었으나, 2) 대부분의 미국 기하 교과서에서는 크기가 있는 점과 선을 소개한 후, '무정의 용어'인 점과 선에 대하여 기하에서의 '점은 크기가 없고', '선은 두께가 없음'을 각각 명시적으로 서술하고 있음을 확인할 수 있었다. 이와 같은 고찰을 통해 본 연구에서는 한국의 2015 개정 교육과정에 따른 중학교 수학 1의 기본도형 내용영역에서의 점과 선에 관한 서술이 잠재적으로 Euclid 기하의 관점에 해당하지 않는 수학적 직관을 생성할 가능성이 있으므로 교수학습 과정에서 이에 대한 언어적 표현의 주의가 필요함을 제안하고자 한다. In this study, mathematical analysis is conducted by focusing to the 'size' of the 'point' and the 'line'. The textbook descriptions of the 'point' and the 'line' in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum and US geometry textbooks were compared and analyzed between. First, as a result of mathematical analysis of' 'the size of a point and a segment', it was found that the mathematical perspectives could be different according to 1) the size of a point is based on the recognition and exclusion of 'infinitesimal', and 2) the size of the segment is based on the 'measure theory' and 'set theory'. Second, as a result of analyzing textbook descriptions of the 'point' and the 'line', 1) in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum, after presenting a learning activity that draws a point with 'physical size' or line, it was developed in a way that describes the 'relationship' between points and lines, but 2) most of the US geometry textbooks introduce points and lines as 'undefined terms' and explicitly states that 'points have no size' and 'lines have no thickness'. Since the description of points and lines in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum may potentially generate mathematical intuitions that do not correspond to the perspective of Euclid geometry, this study suggest that attention is needed in the learning process about points and lines.

요양보호사의 직무스트레스가 고객지향성에 미치는 영향 - 본인인지건강수준의 조절효과

이규희,조경원 보건의료산업학회 2016 보건의료산업학회지 Vol.10 No.3

Objectives : This research analyzed the general characteristics of care workers and verified the correlation among self-perceived health, job stress and customer orientation. Methods : We conducted a survey from May 1st, to May 31st, 2015 of 260 care workers who are affiliated with elderly care facilities or home care facilities in Busan, Korea. Results : The more the workers were stressed about their organizational culture, the more they recognized psychological difficulties. However, there was no correlation between organizational culture and their tendency to be oriented toward customers. It was verified that the recognized psychological health has a positive regulation effect between customer orientation and job stress such as job skill requirement(p<0.01), job autonomy(p<0.01), and organizational culture(p<0.01). Conclusions : Because both suppliers and recipients of care services are aging, it is necessary for elderly care facilities to make a greater effort to minimize the physical and psychological losses of recipients.

Objectives: Analyze of the differences in financial characteristics and those between publicity and profitability. Analyze the differences in financial characteristics and those between publicity and profitability Methods : This study was conducted on 31 regional public hospitals nationwide using financial statements from 2015 and 2018. It compared operations in 2018 when the Moon Jae-in Care policy was implemented to enhance security with operations in 2015 without the policy. Results: Data from 2015 and 2018 were compared using multiple regression analysis to determine the factors that had an influence on medical profit on medical revenue. It was found that twice in 2015 and 2018, the ratio of labor versus medical costs and the ratio of material versus medical costs were positively affected. It was also found that in 2018, city funding per 100 beds was negatively affected. Conclusions: In order to improve the quality of health care, appropriate personnel should be hired and city funding should also be provided to secure public health care.

연속적 공변 상황에 대한 질적 그래프 구성 과제에서 드러난 예비교사들의 추론 양상 분석

이규희,이지현 대한수학교육학회 2020 수학교육학연구 Vol.30 No.3

In Middle School Mathematics 1 of the 2015 revised Korean mathematics curriculum, before the definition of a function, the task of constructing a qualitative graph of the relationship between two changing quantities has been newly proposed. In relation to the changes in the 2015 revised Korean mathematics curriculum, this study explored the reasoning of pre-service teachers revealed in the process of constructing a qualitative graph of the relationship between the two quantities that are continuously changing. Most pre-service teachers constructed graphs by focusing on the covariation than the correspondence on the relationship between the two quantities. Additionally, they successfully reasoned the global shape of the graph by forming the relationship between the two variables as a multiplicative object. However, many pre-service teachers showed difficulty in judging or not judging the differentiable at the point which changes the local shape of graph. Some pre-service teachers thought that the slope of the tangent at the inflection point was zero or invoked time even if it doesn't require. The results in this study suggest that 1) in a continuous covariation situation, the formation of a multiplicative object such as a slope is a critical factor in the process of constructing the global shape of the graph, 2) smooth continuous covariation reasoning is a critical factor in the process of constructing the local shape of the graph, 3) covariation reasoning has a level difference in the process of constructing the global and local shape of the qualitative graph. 2015 개정 교육과정의 중학교 수학 1에서는 함수의 정의 전, 변화하는 두 양의 관계를 질적 그래프로 구성하는 과제를 새롭게 제시하고 있다. 본 연구는 이와 같은 2015 함수 교육과정의 변화와 관련하여 연속적으로 변화하는 두 양의 관계를 질적 그래프로 구성하는 과정에서 드러난 예비교사들의 추론 양상을 탐색하였다. 대부분의 예비교사들은 두 양의 관계식을 세우기보다는 한 양의 변화에 따른 다른 양의 변화에 주목하여 그래프를 구성하였으며, 두 양의 관계를 곱셈적 대상으로 형성하여 그래프의 전체적 개형을 성공적으로 추론하였다. 그러나 그래프의 국소적 개형과 관련하여, 대부분의 예비교사들은 그래프의 국소적 개형이 바뀌는 점(곡선에서 직선으로 바뀌는 점, 변곡점)에서는 미분가능성을 고려하지 않았거나 고려하는 데 어려움을 겪었으며, 일부 예비교사들은 변곡점에서의 접선의 기울기는 이라고 생각하였다. 한편 시간이 등장하지 않는 두 양의 관계에 대한 질적 그래프를 구성할 때도 일부 예비교사들은 시간을 상기하여 추론하였다. 본 연구의 분석은 1) 기울기와 같은 곱셈적 대상의 형성이 연속적으로 변하는 두 양의 관계에 대한 질적 그래프의 전체적 개형 추론에 중요한 요소이다, 2) 그래프의 국소적 개형을 파악하는 데에는 매끄러운 연속 공변 추론이 결정적인 역할을 한다, 3) 질적 그래프의 전체적 개형과 국소적 개형을 구성하기 위한 공변 추론의 수준은 차이가 있음을 시사한다.

"평행사변형은 사다리꼴이다."에서 '이다'에 대한 고찰

이규희,최영기 대한수학교육학회 2016 학교수학 Vol.18 No.3

A word ‘is' in “A parallelogram is trapezoid.” is ambiguous and very rich when it comes to its meaning. In this paper, ‘is' as in everyday language will be identified as semantic primes that can be interpreted in different ways depending on context and situation, and meanings of ‘is' in mathematics will be discussed separately. Focusing on ‘identity', ‘is' will be reinterpreted in the view of equivalence relation and van Hieles' work. ‘Is’, as a mathematical sign, is thought to have a significant importance in producing mathematical ideas meaningfully. “평행사변형은 사다리꼴이다.”에서 ‘이다’는 애매하고 그 의미가 매우 풍부한 기호이다. 이 연구는 일상적 언어 ‘이다’가 문맥과 상황에 따라 다양하게 해석되는 의미원소임을 밝히고 수학에서 사용되는 ‘이다’의 의미를 구분하여 논의한다. 그리고 ‘동일성’의 관념에 주목하여, 수학적으로 ‘같음’을 나타내기 위해 사용되기도 하는 ‘이다’를 동치관계의 개념과 Van Hieles의 기하 사고 수준 이론으로 재해석하여 살펴본다. 수학적 기호로서 ‘이다’에 대한 분석 결과 ‘이다’는 수학적 아이디어를 의미 있게 생성하는 데 중요한 의의가 있다고 판단된다.
