Background: Many chronic obstructive pulmonary disease (COPD) patients receiving monotherapy continue to experience symptoms, exacerbations and poor quality of life. This study aimed to assess the efficacy and safety of direct switch from once-daily tiotropium (TIO) 18 ㎍ to indacaterol/glycopyrronium (IND/GLY) 110/50 ㎍ once daily in COPD patients in Korea. Methods: This was a randomized, open-label, parallel group, 12-week trial in mild-to-moderate COPD patients who received TIO 18 ㎍ once daily for ≥12 weeks prior to study initiation. Patients aged ≥40 years, with predicted post-bronchodilator forced expiratory volume in 1 second (FEV₁) ≥50%, post-bronchodilator FEV₁/forced vital capacity <0.7 and smoking history of ≥10 pack-years were included. Eligible patients were randomized in a 1:1 ratio to either IND/GLY or TIO. The primary objective was to demonstrate superiority of IND/GLY over TIO in pre-dose trough FEV₁ at week 12. Secondary endpoints included transition dyspnea index (TDI) focal score, COPD assessment test (CAT) total score, and rescue medication use following the 12-week treatment, and safety assessment. Results: Of the 442 patients screened, 379 were randomized and 347 completed the study. IND/GLY demonstrated superiority in pre-dose trough FEV₁ versus TIO at week 12 (least squares mean treatment difference [Δ], 50 mL; p=0.013). Also, numerical improvements were observed with IND/GLY in the TDI focal score (Δ, 0.31), CAT total score (Δ, -0.81), and rescue medication use (Δ, -0.09 puffs/day). Both treatments were well tolerated by patients. Conclusion: A direct switch from TIO to IND/GLY provided improvements in lung function and other patient-reported outcomes with an acceptable safety profile in patients with mild-to-moderate airflow limitation.

Purpose : The purpose of this study was to determine factors that affect the quality of life (QoL) of people with diabetes. We hope to provide a basis for intervention strategies for health promotion and related research among patients with diabetes in the field of physical therapy. Methods : We selected individuals diagnosed with diabetes who were aged 19 years or higher by using data from the 2019 Korean Health Panel survey and analyzed the results of 1,527 people. The influencing factors were sex, age, household income, marital status, age, education level, subjective health status, body mass index (BMI), smoking, drinking, regular exercise, experience of depression and anxiety, suicidal thoughts, stress, and frequency of walking (days/week). Frequency analysis, descriptive statistics, independent sample t-test, one-way analysis of variance, and multiple regression analysis were performed. Results : The EQ-5D score for QoL was .87 ± .12, with pain and discomfort being the most detrimental to the QoL of people with diabetes. In terms of patients characteristics, the QoL was lower among participants who were female, older, and separated/widowed/divorced; had an education level below middle school; had a poor subjective health status; were non-smokers and drinkers; and did not walk and exercise regularly, experienced a lot of stress, and experienced depression and anxiety; and had suicidal thoughts (p<.001). Being separated/bereaved/divorced; experiencing a lot of stress, depression, and anxiety; and having suicidal thoughts were negatively associated with QoL in people with diabetes (p<.01). On the other hand, age of 65 years or younger; graduation from high school, fair or better subjective health, regular exercise and alcohol consumption, and walking (days/week) were positively associated with QoL (p<.05). Conclusion : Regarding the QoL of patients with diabetes, intervention strategies should be formulated by considering general characteristics and disease-related characteristics. Among the various factors affecting QoL, the number of walking and regular exercise were found to be the factors that improved the QoL of patients with diabetes. These results can be used as a basis for the education and management of patients with diabetes in the field of physical therapy.

The purpose of this study was to serve as a basis for school health care of better quality, by making a comparative analysis of the health care satisfaction and attitude of elementary school students in consideration of their general characteristics and the presence or absence of nurse teacher. The subjects in this study were 919 selected six graders in 16 elementary schools in the city of Tongduchun, Koyang and Euijungbu, Yangju-kun and Yeunchun-kun. A survey was conducted with questionnaire designed for measurement of health care satisfaction and attitude. As a result of analyzing the data collected from June 1 through 15, 2000, the conclusions were as follows. 1) As for the general characteristics of the students investigated, the subjects included 513 boys(55.8%) and 406 girls(44.2%). The schools where 390(42.4%) students attended were located in municipal area, and the schools where 529(57.6%) students attended were located in kun area. 608(66.2%) students had a nurse teacher at their schools, while 311(33.8%) students had no nurse teacher. 498(54.2%) had an experience to use the health room this year, but 421(45.8%) had no such an experience. Their mean school life satisfaction was scored $3.42{\pm}.71$, above the average. And their health condition was rated $3.81{\pm}.87$, which implied they tended to be in good health. 2) The mean satisfaction at the health room operation was scored $3.33{\pm}.71$, above the medium level. What they were most satisfied with($4.02{\pm}1.08$) was, among the health room facilities, that there were beds. But they expressed the least satisfaction($2.83{\pm}1.17$) at the location of health room. The presence or absence of nurse teacher made a significant difference to their satisfactionat health room operation, because the students in schools with nurse teacher showed greater satisfaction($3.42{\pm}.72$) than the others in schools with no nurse teacher did($3.15{\pm}.66$). 3) Concerning their attitude to use the health room in case of disease or accident occurrence, a lot of students in schools with a nurse teacher, who had ever suffered from indigestion, headache or traumatic injury, used the health room. In schools with no nurse teacher, there was a tendency to talk to their class teachers(p<.001). The recognition of the necessity for health counseling was generally on a medium level. The counselor whom they wanted to discuss health problem with was family or friend in the largest cases. Few students discussed with class teachers in case there was a nurse teacher in school. Instead, some of them discussed with friend, family or nurse teacher, and there was a significant difference between them(p<.001). 4) The mean satisfaction at health, sanitation and environmental management was rated $3.20{\pm}.90$, above the average. The classroom lighting gave them the best satisfaction with $3.67{\pm}1.07$, but the satisfaction at toilet cleanness and disinfection was not good with $2.83{\pm}1.19$. By the presence or absence of nurse teacher, those who had a nurse teacher expressed better satisfaction at water supply facilities including hot water than the others who had no nurse teacher did(p<.001). But no significant difference was observed in the other items. 5) The health education satisfaction was rated $3.19{\pm}.99$, which was on a medium level. By item, the mean satisfaction level was $3.36{\pm}1.19$ at nurse teacher's explanation about treatment, $3.13{\pm}1.15$ at the frequency of health education, and $3.08{\pm}1.16$ at the explanation on the cause of disease. By the presence or absence of nurse teacher, the students with nurse teacher showed significantly better satisfaction at every factor0(p<.001). 6) Regarding health education attitude, their recognition of the need for school health education was scored $3.89{\pm}.96$. Those who had a nurse teacher felt it more necessary($3.96{\pm}.92$), yet the others who had no nurse teacher felt its necessity a little less($3.74{\pm}1.01$). The most preferred thing for them to learn in health education was first aid, followed by sex education, obesity prevention, safety accident prevention in school and outdoors, smoking-related health, good use of leisure time, and environmental pollution cause in the order named. According to the presence or absence of nurse teacher, there was a significant difference in sex education(p<.01), but no significant disparities were found in the other factors. The most preferred person who would offer health education was a lecturer from the outside(45.8%) and nurse teacher(45.4%). Their preference for class teacher as a person in charge of health education was just 8.8%. But the presence or absence of nurse teacher didn't produce any differences to their preference for a person in charge of health education.

Objectives : OHIP-14 and EQ-5D were used, targeting the residents of farming communities to identify the elements that influence oral cavity's health and quality of life due to health and to identify the importance of oral cavity's health in order to increase health of adults' oral cavity and quality of life via improved health. Methods : This research was conducted from July 17th, 2010 to August 16th, 2010 targeting 600 residents in Goryeong-gun, Gyeongsangbuk-do, aging over 40. The data has been analyzed using Mann-Whitney U test, Kruskal-Wallis test and hierarchical multiple regression through SPSS Win Program 18.0 version. Results : 1. OHIP-14 and EQ-5D based on general characteristics showed lower oral health-related quality of life and health-related quality of life on the following cases: women (p=0.004, p<0.001), older (p<0.001, p<0.001), lower scholastic ability (p<0.001, p<0.001), lower average of average spending money (p<0.001, p<0.001), higher number of chronic disease (p<0.001, p<0.001), less drinking (p=0.012, p=0.008), lower perceived oral health and health status (p<0.001, p<0.001) and non smoking showed only EQ-5D (p<0.001). 2. OHIP-14 and EQ-5D based on oral health behavior showed lower oral health-related quality of life and health-related quality of life on the following cases: no periodic oral check-up (p<0.001, p<0.001), less experience of oral health education (p<0.001, p<0.001), horizontal tooth-brushing method(p<0.001, p<0.001) and lower frequency of tooth-brushing showed only OHIP-14 (p=0.042). OHIP-14 and EQ-5D based on oral health status and subjective oral symptom showed lower oral health-related quality of life and health-related quality of life on following cases: number of existing tooth less than 20 (p<0.001, p<0.001), the number of missing teeth more than 9 (p<0.001, p=0.044), DMFT (Decay, Missing, Filling Teeth) index more than 18 (p<0.001, p<0.001), wears denture (p<0.001, p<0.001), edentulous (p<0.001, p=0.002), have xerostomia (p<0.001, p<0.001) and have chewing discomfort (p<0.001, p<0.001). 3. Factors affecting OHIP-14 were gender, age, perceived oral health status, perceived health status, number of existing teeth, dental status, xerostomia and chewing discomfort, and the of reliability (how well it explains) the final model was 48.7%. EQ-5D showed relevance on gender, age, presence of chronic disease, perceived health status, xerostomia, chewing discomfort and oral health-related quality of life, and the reliability of the final model was 42.9%. Conclusions : In order to improve the quality of life of ruralists, oral health needs to be improved or remained by increasing the rate of possession of the existing teeth and preventing the loss of teeth. In order to do so, improvement of accessibility of dental clinic, change of direction from treatment-centered to prevention-centered health care system, development of oral health education program and various oral health care policies which would vitalize continuous oral health care system are considered to be necessary.

목적 본 연구는 중학생의 인구사회학적, 건강행태 특성별 성경험률과 그 영향요인을 파악하기 위해 수행되었다. 방법 제8차 청소년건강행태온라인조사 자료를 이용하여 중학생 37,297명을 분석에 이용하였으며, 다단계층화집락추출에 의한 자료이므로 청소년건강행태온라인조사에서 제시한 복합표본설계정보(층화, 집락, 가중치)를 반영하여 SPSS WIN 18.0 프로그램으로 분석하였다. 결과 남학생의 성경험은 주관적으로 인식하는 경제상태가 중간인 경우보다 높을 때 1.54배(95% CI [1.20, 1.96]), 낮을 때 1.43배(95% CI [1.08, 1.89]) 증가하였고, 양쪽 부모님이 모두 안 계실 때 2.68배(95% CI [1.82, 3.96]), 아르바이트 경험이 있는 경우 1.98배(95% CI [1.43, 2.74]) 성경험률이 증가하였다. 음주, 흡연, 약물을 할 경우 각각 2.35배(95% CI [1.79, 3.08]), 2.35배(95% CI [1.76, 3.14]), 4.17배(95% CI [2.81, 6.19]) 성경험이 증가하고 우울할 때 1.32배(95% CI [1.01, 1.71]), 자살생각이 있을 때 1.43배(95% CI [1.09, 1.89]), 성교육을 받지 않았을 때 1.67배(95% CI [1.35, 2.08]) 성경험률이 증가하였다. 여학생인 경우는 주관적으로 인식하는 경제상태가 중간인 경우보다 높을 때 1.87배(95% CI [1.30, 2.70]), 아르바이트 경험이 있는 경우 1.79배(95% CI [1.21, 2.67]) 성경험률이 증가하였다. 흡연을 할 경우 3.95배(95% CI [2.56, 6.10]), 약물을 사용할 경우 5.48배(95% CI [2.80, 10.74]) 성경험률이 증가하고 우울할 때 1.65배(95% CI [1.17, 2.31]), 스트레스가 조금인 경우보다 없을 때 2.30배(95% CI [1.18, 4.48]), 성교육을 받지 않았을 때 1.50배(95% CI [1.09, 2.07]) 성경험률이 증가하였다. 반면 부모학력이 중졸이하보다 고졸일 경우와 1학년보다 2학년의 경우 성경험률이 낮았다. 결론 남녀 중학생의 공통된 성경험 영향요인은 가정 경제수준, 아르바이트 경험, 현재 흡연, 약물사용, 우울, 성교육이었고, 남학생의 경우 양쪽 부모 동거 상태, 음주, 자살생각이 여학생과는 다른 관련 요인이었으며 여학생의 경우 부모학력, 스트레스, 학년이 남학생과는 다른 영향요인이었다. 성경험과 관련하여 남녀 학생별로 영향요인에 차이가 있기 때문에 남녀별로 차별화된 성건강 중재개발이 요구되며 성경험이 음주, 흡연, 약물 등의 문제행동과 함께 나타나므로 중학생의 성건강을 위해서는 단편적인 성교육 프로그램보다 정신건강 및 건강습관의 틀과 함께 접근해야 할 것으로 보인다.

배경: 본 연구는 1981년 11월부터 1997년 6월까지 관상동맥 우회술을 받은 500례의 협심증 환자를 대상으로 술전 진단, 수술방법, 수술사망률, 수술합병증, 술후 증상의 재발과 치료에 대해 알아보았다. 대상 및 방법: 500례 중 남자는 330례, 여자는 170례였고 평균 연령은 57.4$\pm$8.9세였다. 술전 환자의 평가를 위해 심전도, 심에코, MIBI scan, 내경동맥과 대퇴동맥에 대한 Duplex Sono, CK, LDH를 포함한 일반적인 혈액 검사, 관상동맥 조영술 등을 시행하였으며, 술후 부정맥과 심근경색증 등의 합병증에 대한 판정 지표로 삼았다. 결과: 술전 진단으로 불안정성 협심증이 282례 (56.4%), 안정성 협심증이 141례 (28.2%), 심근경색후 협심증이 58례 (11.6%), 급성 심근경색증이 8례 (1.6%), 이형 협심증이 7례 (1.4%), 경피적 관상동맥확장술 실패가 4례 (0.8%)였다. 술전 관상동맥 조영술 상 삼혈관 질환이 263례 (52.6%), 이혈관 질환이 93례 (18.6%), 단일혈관 질환이 71례 (14.2%)였으며, 좌주관상동맥 질환이 68례 (13.6%), 그외 5례(1.0%) 있었다. 환자들은 술전 여러 가지 관상동맥 질환의 위험인자들에 노출되어 있었으며 고혈압, 흡연, 비만, 당뇨 등의 빈도가 점차 증가하고 있었다. 수술은 대복재정맥 1143문합, 내흉동맥 442문합, 요골동맥 17문합, 위대망막 동맥 1문합으로 환자당 평균 3.2$\pm$1.2문합을 시행하였으며, 인공판막 치환술 또는 성형술이 동시에 시행된 경우가 31례 (6.2%), 관상동맥 내막절제술 또는 성형술이 27례 (5.4%), 좌주관상동맥 성형술이 13례 (2.6%), 내경동맥 내막절제술이 5례 (1.0%), Maze 술식이 3례 (0.6%), 기타 술식이 11례 (2.2%) 등에서 시행되었다. 수술시간은 대동맥차단 시간이 평균 99$\pm$67분이었다. 수술사망률은 6.8% (34/500)이었고, 여성, 심근경색증 \ulcorner과거력, 급성 심근경색증과 응급수술 등이 유의한 위험인자로 나타났다. 합병증으로서 부정맥 109례 (21.8%), 신경학적 합병증 27례 (5.4%), 출혈 25례 (5.0%), 수술전후 심근경색증 25례 (5.0%), 종격동염을 포함한 창상감염 20례 (4.0%), 저심박출증 18례 (3.6%), 급성 신부전증 12례 (2.4%), 폐렴 등의 기타 합병증이 10례(2.0%)있었다. 술후 추적기간은 평균 25$\pm$23개월이었으며, 증상의 재발로 인한 재수술은 5명의 환자에서 시행되었다. 결론: 수술경험의 축적, 심근보호법의 다양한 적용, 심기능 보조장치의 적극적인 사용으로 고위험군 환자의 증가에도 불구하고 수술사망률을 감소시킬 수 있으리라 기대된다.
