Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

S-277 Prognostic value of echocadiography for CKD patients with HF with reduced EF initiating hemodialysis

( Kyunghee Lim ),( Jin-oh Choi1 ) 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1

Background: Heart failure (HF) is highly prevalent in patients with chronic kidney disease (CKD). Among the CKD patients initiating hemodialysis, left ventricular (LV) systolic dysfunction was reported up to 15 %. The aim of this study was to evaluate value of echocardiography to determine adverse cardiac outcomes in CKD patients with heart failure with reduced ejection fraction (HFrEF). Methods: In this retrospective study, we surveyed 843 patients with both advanced CKD and HF who were starting hemodialysis in our hospital during the period 2005 - 2015. HFrEF was defined by LVEF ≤ 50 % with symptoms of HF. We inspected echocardiography, comorbidity, medication, laboratory findings in 94 patients with advanced CKD and HFrEF. The primary endpoint was comparison of echocardiographic parameters between hospitalization group and non-hospitaliztion group and secondary endpoints was all cause mortality in between two group. Results: 40 (42 %) patients were hospitalized caused by HF, and 18 (19.1 %) patients were deceased. Before initiation of hemodialysis, LV end-systolic (LVIDs) and end-diastolic diameter (LVIDd) were higher in patients with experience of hospitalization due to HF than patients without hospitalization (LVIDd: 60.5±8.14 mm vs 56.5±7.16, p=0.016) (LVIDs: 46.5±9.2 vs 41.7±8.0, p=0.01). Also There was a difference in relative wall thickness (RWT) between the two groups (0.334±0.073 vs 0.365±0.077, p=0.047) The 4.3-year survival rates of two group were 93.2% and 56.4 respectively by the Kaplan-Meier survival estimation (p=0.005). Conclusions: In CKD with HFrEF, LVIDs, LVIDd and RWT were strong predictors for adverse cardiac outcomes. Identification and measurement of LVIDs, LVIDd, RWT significantly improve risk stratification in high risk population

( Lee¸ Kyunghee ),( Heo¸ Youngjin ),( Han¸ Mihwa ),( Kim¸ Mijung ),( Choi¸ Hyunseok ) 한국정신간호학회 2021 정신간호학회지 Vol.30 No.3

Purpose: The aim of this study was to determine the reliability and validity of the metacognition rating scale (MCRS), which is a revised version of the existing metacognition questionnaire (MCQ) with anger and anxiety added. Methods: A survey was conducted on 591 nursing students at colleges in North and South Gyeongsang Provinces, South Korea. The collected data were processed for the reliability and validity of the MCRS through Cronbach’s α and confirmatory factor analysis using SPSS 26.0. Results: Cronbach’s α for the reliability of MCRS was calculated at .88, .86, .77, .74, and .66 for five subfactors. Among the five subfactors, the first, second, third, and fifth factors showed high correlation in each of six items. Factor 4 was highly correlated in 5 out of 6 questions. Conclusion: The data confirm that the MCQ revised to include anger and anxiety is both reliable and valid for nursing students. Therefore, this scale can be used to identify the maladaptive metacognition of nursing students in stressful situations.

중학교 과학 수업에서 교사와 학생의 언어적 상호작용 분석

최경희,박종윤,최병순,남정희,최경순,이기순 한국과학교육학회 2004 한국과학교육학회지 Vol.24 No.6

이 연구의 목적은 중학교 과학 수업에서 교사와 학생간의 언어적 상호작용이 실제로 어떻게 이루어지고 있는지를 관찰ㆍ분석하여 이에 대한 특징을 추출함으로써 과학 수업에서 교사와 학생간의 언어적 상호작용에 대한 기초 자료를 제공하는데 있다. 이를 위해 수업 분석 준거를 개발하였으며, 8명의 과학 교사의 수업 12차시를 관찰 및 녹화하였으며, 교사와의 면담을 실시하였다. 수업 분석 결과, 관찰한 과학 수업에서 교사와 학생간의 언어적 상호작용은 주로 교사의 단순 확인/기억 질문, 학생의 단답형 응답, 교사의 즉각적 피드백이 주를 이루었다. 교사가 사고 질문을 하고 지연 피드백을 부여 하는 경우 학생들이 자신의 생각을 드러내고 이를 기반으로 사고를 진전시켜 나갈 수 있었으나 이러한 사례는 그 수가 상당히 적었다. 교사들은 학생들의 사고를 유발하고 이를 진전시키기 위한 노력보다는 수업 내용을 논리적 흐름에 맞추어 체계적으로 제시하는 것에 더 큰 중점을 두는 경향이 있었다. 또한 관찰한 수업에서 교사가 시범 실험, 모형 혹은 실물 수업자료 등을 활용할 때 보다 많은 수의 학생들이 적극적으로 수업에 참여하여 자신의 생각을 드러내었으나 교사가 학생들의 생각을 바탕으로 학생들의 사고과정을 진전시켜 나가는 과정을 도모하지 않음으로써 학생들의 사고과정을 단절시키는 경우가 많았다. 따라서 수업 활동과 수업 자료 활용이 효과를 거두기 위해서는 각각의 활용에 있어서 학생들과 구체적으로 어떠한 상호 작용을 형성해야 하는지에 대해 연구가 이루어져야하며, 또한 교사는 교사의 질문이나 피드백이 학생들의 학습에 중요한 역할을 함을 인식해야 한다. The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.

Neurological Complications Resulting from Non-Oral Occupational Methanol Poisoning

Choi, Ji-Hyun,Lee, Seung Keun,Gil, Young-Eun,Ryu, Jia,Jung-Choi, Kyunghee,Kim, Hyunjoo,Choi, Jun Young,Park, Sun Ah,Lee, Hyang Woon,Yun, Ji Young The Korean Academy of Medical Sciences 2017 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.32 No.2

<P>Methanol poisoning results in neurological complications including visual disturbances, bilateral putaminal hemorrhagic necrosis, parkinsonism, cerebral edema, coma, or seizures. Almost all reported cases of methanol poisoning are caused by oral ingestion of methanol. However, recently there was an outbreak of methanol poisoning via non-oral exposure that resulted in severe neurological complications to a few workers at industrial sites in Korea. We present 3 patients who had severe neurological complications resulting from non-oral occupational methanol poisoning. Even though initial metabolic acidosis and mental changes were improved with hemodialysis, all of the 3 patients presented optic atrophy and ataxia or parkinsonism as neurological complications resulting from methanol poisoning. In order to manage it adequately, as well as to prevent it, physicians should recognize that methanol poisoning by non-oral exposure can cause neurologic complications.</P>

Seasonal occurrence of Grapholita dimorpha, new insect pest in apple orchards

KyungHee Choi,Dong-Hyuk Lee,Yugi Min 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10

Major fruit moths in commercial apple orchards are known as Carposina sasakii and Grapholita molesta. In addition, recently G. molesta is dominant species compared with C. sasakii in apple orcahrds. In case of Japan, the fruit damage occurred a lot unexpectedly in apple orchards of the northern Nagano during the harvesting season in 2004. As the result of identifying after emerging the larvae collected from the damaged fruit, Grapholita dimorpha was found out. The morphology of Grapholita dimorpha are almost similar to that of Grapholita molesta, and the shape of the damaged fruits was too similar to distinguish them. We installed sex pheromone traps of Grapholita dimorpha in apple orchards to check if there were Grapholita dimorpha in Korean apple orchards and to survey seasonal occurrence. As a result of survey by installing sex pheromone traps of G. dimorpha at one apple orchard in Uiseong-Gun and Gunwi-Gun area respectively, we could find high population density of G. dimorpha in sex pheromone traps. The peak of the first generation of G. dimorpha was dated in early May. The first generation occurrence of G. molesta in sex pheromone traps was lower than that of Grapholita molesta. However, it had higher occurrence of sex pheromone traps than G. molesta since it increased after mid and late July. Also, as a result of identifying in G. molesta traps, there were 673 G. molesta and 8 G. dimorpha. As a result of survey of 1,102 G. dimorpha in its sex pheromone traps, there were 1,099 G. dimorphaand 3 G. molesta.

A Study on Learning to Write English Interrogative Sentences

Kyunghee Choi 한국영어어문교육학회 2012 영어어문교육 Vol.18 No.2

This paper aims to discuss the effects of learning how to write English interrogative sentences. 122 students who participated in the study learned basic structural components of English questions and practiced writing questions by inversing the subject and the verb in a given declarative sentence. The participants were divided into two groups: Group 1 which was given a brief explanation of interrogative structures and practices, and Group 2 which was given the same explanation and practices in addition to an assignment for which they had to make one or two comprehension questions based on reading a passage. For the pre-tests and the post-tests, they took a TOEIC reading test with 40 questions and a structure test with 25 questions. The results of the tests show that both groups improved significantly in the two post-tests, benefiting from this learning method. However, the additional treatment for Group 2 did not seem to be highly effective. In the questionnaire survey, the participants think that the method of learning English questions has helped them better understand English grammar as well as interrogative structures. The participants were also divided into three different levels: high, intermediate, and low. The intermediate level group students benefited most from learning writing questions as the results of the post-test of the 25-questions test and the final exam of the course show.
