Considering the four arithmetical operations, the operations over some problems in the second half periods of Chosun Dynasty were dealt in the different dimensions were not reasonable and tile units of the dimensions were neglected. This paper aims to introduce some questionable solved problems related to tile equations higher than tile second degree.

A Note on the KC, UC and US Spaces

柳寅永 圓光大學校大學院 1981 學位論叢 Vol.6-2 No.-

Wilansky가 [3, p.265]에 "locally compact US가 반드시 T₂-공간이 되는가?"라고 문제를 제시하였다. 본 논문은 Wilansky의 문제가 일반적으로 진이 아님을 반례를 들어 증명하고 KC, UC, US 공간들 사이의 관계를 조사함을 목적으로 한다. 주요 정리는 다음과 같다. [정리1] T₂⇒KC⇒UC⇒US⇒T₂: 역 포함관계는 성립하지 않는다. [정리2] 제 1 가산공간에서는, T₂≡KC≡US이다. [정리3] X가 KC이면 X^(*), the one point compactification of X, 는 UC이다. [정리4] 각 X_(i)가 UC이면, Ⅱ_(i)X_(i)도 UC이다.

Doctoral professionals who majored Home Economics Education are relatively rare and recently have been produced in a limited number of institutions. The purpose of this paper was to analyze the Ph.D. Dissertation majored in Home Economics Education by research subjects and methods. Just twenty dissertations published in domestic universities were selected through internet search to be analyzed in this paper. This research showed five research subject areas of the dissertation such as core concepts and perspectives, curriculum, teaching and learning, teachers empowerment, and others. Each subject had three to five references and time difference in publication. The research subject related to concepts and perspectives was more likely to be studied in an early stage, followed by the subject of curriculum. The research subject became to be varied to teaching and learning and teachers empowerment areas. The research methods were associated with the research subject, as expected. Literature analysis was common in the subject on concepts and perspectives, curriculum, and textbook analysis, while survey was in teachers empowerment. Teaching and learning subject used various research methods together. Numerous dissertation with variety of research subjects and methods would be expected to be followed to develop research on Home Economics Education.

The purpose of this study was to examine depression and factors that influence depression in elderly people. The participants for this study were 97 elderly people living in Gyonggi Province, Korea. Data were collected from September 9 to 14, 2002 using a structured questionnaire. SPSS/WIN 10.0 was used to provide descriptive statistics, Pearson's correlation coefficient and stepwise multiple regression for data analysis. Of the 97 elderly people, 52 were found to have depression (53.6%). Depression showed a positive correlation with the number of chronic diseases (r=.304, p<.01) and negative correlations with self-reported health tatus (r=-.556, p<.001) and social support (r=-.381, p<.001). Depression was influenced by self- reported health status, economic status, and social support (R2= .453, F=21.49, p<.001). Based upon these results, it is suggested that mental health services which provide professional support and reduce depression are essential components of a health promotion service for elderly people and should be linked to social welfare service.

Linezolid Resistance in Methicillin-Resistant Staphylococcus aureus in Korea: High Rate of False Resistance to Linezolid by the VITEK 2 System

유인영,On-Kyun Kang,Hyang Jin Shim,허희재,Nam Yong Lee 대한진단검사의학회 2020 Annals of Laboratory Medicine Vol.40 No.1

As various linezolid resistance mechanisms have been identified in methicillin-resistant Staphylococcus aureus (MRSA), we investigated the molecular characteristics of MRSA with elevated linezolid minimum inhibitory concentrations (MICs), using the VITEK 2 system (bioMérieux, Marcy-l’Étoile, France). Twenty-seven MRSA isolates from 14 patients exhibiting linezolid MICs ≥8 μg/mL were examined by broth microdilution (BMD) test as well as by sequencing for mutations in the 23S rRNA gene or ribosomal proteins (L3, L4, and L22) and the presence of the optrA, cfr, and cfr(B) genes. Of the 27 isolates, four (14.8%) from one patient were confirmed as linezolid resistant by BMD and harbored a 23S rRNA T2500A mutation. The remaining 23 were confirmed as linezolid susceptible, indicating that the linezolid-resistant results were major errors generated by VITEK 2. The most commonly detected mutation (19/27, 70.4%), L3 Gly152Asp, was detected in only linezolid-susceptible isolates. No isolates contained optrA, cfr, or cfr(B) or any L4 or L22 protein alterations. Our results show that the 23S rRNA T2500A mutation was mainly associated with linezolid resistance, while the L3 Gly152Asp mutation was not related to linezolid resistance. A confirmatory test is recommended for VITEK 2 linezolid-resistant results owing to the high probability of false resistant results.

가정교과 교사의 수행평가에 대한 태도와 실시현황에 대한 연구

유인영,윤인경 한국가정과교육학회 2001 한국가정과교육학회지 Vol.13 No.1

The purpose of this research is to study the performance assessment made by high school home economics teachers : their awareness and attitudes toward the assessment correlate with the qualitative output of the executions of it. as well s to determine how their awareness and attitudes toward the assesment correlate with the qualitative output of the executions of their performance assessments. The research has yielded the following results : 1. The attitudinal score shows above average of 58.7/90. By the sub-factors. awareness of the characteristics of performance assessment is 20.6/30 : the favorable attitudinal score is at 20.0/30. the behavioral attention at 9.5/15. and the effects of performance assessment on the teachers and the classes at 8.6/15. 2. In a single semester. the highest frequency of executing performance assessment is between 1 to 2 times (58.7%). and practical skill test is proven to be the most frequently used category at 79.9%. 3. The correlation between the overall attitude on performance assessment and the quality of actual performance assessment executed is high. indicating superior quality of performance assessment. which is directly proportionate to the enhanced attitude of teachers on performance assessment.

백워드 디자인에 기반한 고등학교 ‘건강한 커플관계’ 교육과정(안) 개발

유인영,박미정 한국가정과교육학회 2019 한국가정과교육학회지 Vol.31 No.3

본 연구는 백워드 디자인에 기반하여 고등학교 가정교과의 ‘건강한 커플관계’ 교육과정(안)을 개발하는데 목적이 있다. 이에따라 문헌 분석을 통해 ‘건강한 커플관계’의 내용요소를 추출하고, 가정과교사 197명, 고등학생 154명을 대상으로 ‘건강한 커플관계’ 내용 요구도 조사를 하였다. 이를 바탕으로 백워드 교육과정 설계 모형으로 고등학교 가정교과의 ‘건강한 커플관계’ 교육과정(안)을 개발하여 전문가집단의 타당도 검증을 받았다. 본 연구의 결과로 첫째, ‘건강한 커플관계’ 내용 요소에 대하여 5점 리커트 척도로 요구도를 조사한 결과, 전체 내용 요소에대한 평균은 가정과 교사 4.39, 고등학생 4.02였으며, ‘데이트 폭력에 대한 이해’의 내용 요소가 교사 4.70, 학생 4.19로 두 집단에서모두 가장 높게 나타났다. 둘째, 고등학교 가정교과의 ‘건강한 커플관계’ 교육과정(안)은 교육과정 목표와 2개의 단원으로 구성되었고, 각 단원은 단원 목표, 세부 학습 주제 및 내용 요소, 평가계획, 수업계획을 포함하였다. 각 단원별에 대하여 템플릿을구성하여 총 2개의 템플릿을 구성하였다. 본 연구는 고교학점제 시행에 대비하여 고등학교 가정교과의 선택과목으로 ‘건강한 커플관계’ 교육과정(안)을 제안하고, 선택 과목 개설의 기반을 마련한 것에 의의가 있다. The purpose of this study is to develop a 'Healthy Couple Relationship' curriculum(plan) for high school home economics based on backward design. In this study, the content elements of 'Healthy Couple Relationship' were extracted through literature analysis, and the need for contents of 'Healthy Couple Relationship' was surveyed in 197 families of home economics teachers and 154 high school students. Based on this, the 'Healthy Couple Relationship' curriculum(plan) of high school home economics curriculum was developed as the backward design, and it was verified by the expert group. The results are as follows: First, when measured on a 5-point Likert scale, the mean scores of the need for content elements of 'Healthy Couple Relationship' was 4.39 for teachers, and 4.02 for students, respectively. The content elements of 'understanding dating violence' was 4.70 for teachers and 4.19 for students. Second, the developed 'Healthy Couple Relationship' curriculum consists of two templates, one for each unit, including curriculum goals, unit composition and unit goals, 8 learning subjects and content elements, evaluation plans including 24 lesson plans. In this study, it is meaningful to propose a "Healthy Couple Relationship" curriculum as an elective course in high school home economics curriculum in preparation for the high school credit system, and to lay the foundations for opening elective courses.
