Chronic obstructive pulmonary disease (COPD) is characterized by a diverse array of pulmonary and nonpulmonary manifestations, but our understanding of COPD pathogenesis and the factors that influence its heterogeneity in disease presentation is poor. Despite this heterogeneity, treatment algorithms are primarily driven by a single measurement, forced expiratory volume in 1 second ($FEV_1$) as a percentage of its predicted value ($FEV_1%$). In 2011, a major shift in Global Initiative for Chronic Obstructive Lung Disease (GOLD) treatment recommendations was proposed that stratifies patients with COPD on the basis of symptoms and exacerbation history. This article reviews the work reported in 2013 that enlightens our understanding of COPD with respect to COPD classification systems, phenotype, biomarker, exacerbation, and management for patients with COPD.

Purpose: This study seeks to examine prevalence, risk factors, and quality of life of Korean adults with Chronic Obstructive Pulmonary Disease (COPD). Methods: From the database of the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV-1, 2008), the researchers selected 1,458 adults over the age of 45. The original study was a population-based epidemiological survey of health and nutrition with a stratified multistage clustered probability design. Prevalence of COPD was computed on the basis of the sampling weight. Data were analyzed using descriptive statistics, ${\chi}^2$ test, t-test and multiple logistic regression with the SPSS WIN 18.0 and SAS Ver. 9.1 program. Results: The prevalence of COPD was 18.0% among people older than 45 yr. The prevalence of current smokers was 19.7% in this population and 26.3% in individuals with COPD. Age, gender, education, and smoking levels were found to be risk factors for COPD. Significant difference in quality of life was founded between adults with COPD and the healthy controls. Conclusion: The results of this study indicate that COPD is a highly prevalent disease in Korea. To reduce the prevalence of COPD and improve health-related quality of life in patients with COPD, nursing interventions must focus on prevention of risk factors.

Purpose: The purpose of this study was to identify the factors influencing health-related quality of life (HRQOL) of patients with chronic obstructive pulmonary disease (COPD). Methods: A sample of 108 Patients diagnosed with COPD was recruited from outpatients, at a university hospital. Data were collected from February to April in 2016 using the St. George's Respiratory Questionnaire, the Hospital Anxiety-Depression Scale, and the COPD Self-efficacy scale. Results: The average score of HRQOL was 47.56 in patients with COPD. Results of the regression analysis showed that dyspnea phase (${\beta}$=.34, p<.001) and presence or absence of oxygen (${\beta}$=.20, p=.009), anxiety (${\beta}$=.29, p<.001), $FEV_1$ % predicted (${\beta}$=-.15, p=.014) were statistically significant in patients' HRQOL. Conclusion: The research findings show that dyspnea phase and anxiety among psychological factors were the most powerful factors that explain the HRQOL of COPD patients when the demographic and disease characteristics were controlled. Identification of quality of life-related factors should be used to inform targeted interventions, in order to improve HRQOL and help patients' cope.

1. Objectives: This study is to investigate the association of Sasang Constitution and chronic obstructive pulmonary disease(COPD). 2. Methods: One thousand five hundred forty five persons, more than 40 years old, participated in the community based cohort in Wonju City and Pyeongchang City of South Korea from October 29th in 2007 to February 26th in 2008. The diagnosis of COPD was confirmed by spirometry and based on the diagnostic criteria developed by GOLD (Global Initiative for Chronic Obstructive Lung Disease) standard. Relating items like height, weight, BMI(Body Mass Index), martial status, income, drinking, smoking and education were checked using questionnaires and Sasang Constitution was diagnosed by a specialist using PSSC(Phonetic System for Sasang Constitution), facial photos and check-up lists. 3. Results: There were 88 persons(5.7%) who had mild COPD. Old age(more than 60's) and male were significant risk factors of COPD. But smoking, drinking and Sasang Constitution were not risk factors of COPD. But there were many Soeumin who had mild COPD in terms of Sasang Constitution irrespective of sex. 4. Conclusions: Low BMI(<23kg/m2) and low income also were significant risk factors. And Sasang Constitution might be the variable to manage COPD patients, but more researches are needed.

Purpose: This study examined the validity and reliability of the Korean version of the Self-Care in Chronic Obstructive Pulmonary Disease Inventory (SC-COPDI) and the Chronic Obstructive Pulmonary Disease Self-Care Self-Efficacy Scale (SCES-COPD). The SC-COPDI consists of the Self-Care Maintenance Scale (SCMES), Self-Care Monitoring Scale (SCMOS), and Self-Care Management Scale (SCMAS). Methods: The original tool was translated using a back-translation process. Participants were 241 patients with COPD at the Chonnam National University Hospital in Korea. The construct validity was verified through confirmatory factor analysis, and reliability was verified using Cronbach's α. Results: The SCMES consisted of 10 items of three factors-one of four factors was deleted from the original tool. In the SCMOS, there were six items of two factors after two items were deleted from the original tool. The SCMAS consisted of the original 10 items of three factors. The SCES-COPD consisted of six items of two factors, with one item removed from the original tool. The model fit indices of all tools were good, and the construct validity was confirmed. Cronbach's α of SCMES was .72, SCMOS was .90, SCMAS was .81, and SCES-COPD was .85. Conclusion: The Korean version of SC-COPDI and SCES-COPD are valid and reliable instruments for measuring self-care in people with COPD. These instruments can be used in self-care studies of COPD patients in Korea.

Background: The Korean Obstructive Lung Disease (KOLD) Cohort Study is a prospective longitudinal study of patients with chronic obstructive pulmonary disease (COPD), asthma, or other unclassified obstructive lung diseases. It was designed to develop new classification models and biomarkers that predict clinically relevant outcomes for patients with obstructive lung diseases. Methods: Patients over 18 years old who have chronic respiratory symptoms and airflow limitations or bronchial hyper-responsiveness were enrolled at 17 centers in South Korea. After a baseline visit, the subjects were followed up every 3 months for various assessments. Results: From June 2005 to October 2013, a total of 477 subjects (433 [91%] males; 381 [80%] diagnosed with COPD) were enrolled. Analyses of the KOLD Cohort Study identified distinct phenotypes in patients with COPD, and predictors of therapeutic responses and exacerbations as well as the factors related to pulmonary hypertension in COPD. In addition, several genotypes were associated with radiological phenotypes and therapeutic responses among Korean COPD patients. Conclusion: The KOLD Cohort Study is one of the leading long-term prospective longitudinal studies investigating heterogeneity of the COPD and is expected to provide new insights for pathogenesis and the long-term progression of COPD.

Natural sleep pattern and its physiology in childhood are much different from those in adulthood. Several aspects of clinical evaluation for sleepiness in childhood are more difficult than in adulthood. These difficulties are due to several factors. First, excessive sleepiness in childhood do not always develop functional impairments. Second, objective test such as MSLT may not be reliable since it is hard to be certain that the child understand instructions. Third, sleepiness in children is often obscured by irritability. paradoxical hyperactivity, or behavioral disturbances. Anseguently, careful clinical evaluation is needed for the sleepy children. Usual causes of sleepiness in children are the disorders that induce insufficient sleep such as sleep apnea syndrome, schedule disorder, underlying medical and psychiatric disorder, and so forth. After excluding such factors, we can diagnose the hypersomnic disorders such as narcolepsy, Kleine-Levin syndrome, and idiopathic central nervous system hypersomnia. Among the variety of those causes of sleepiness, I reviewed the clinical difference of narcolepsy and obstructive sleep apnea syndrome in childhood compared with in adulthood. Recognition of the childhood narcolepsy is difficult because even severely sleepy children often do not develop pathognomic cataplexy and associated REM phenomena until much later. Since childhood narcolepsy give srise to many psychological, academical problem. Practicers should be concerned about these aspects. Childhood obstructive sleep apnea syndrome is different from adult obstructive sleep apnea syndrome too. Several aspects such as pathophysiology. clinical feature, diagnostic criteria, complication, management, and prognosis differ from those in the adult syndrome. An important feature of childhood obstructive sleep apnea syndrome is the variety of severe complications such as behavioral disorders, cognitive impairment, cardiovascular symptoms, developmental delay, and ever death. Fortunately, surgical interventions like adenotosillectomy or UPPP are more effective for Childhood OSA than adult form. CPAP is a "safe, effective, and well-tolerated" treatment modality too. So if early detection and proper management of childhood OSA were done, the severe complication would be prevented or ever cured.

Objectives: Alongside smoking, occupational exposure is an important risk factor for chronic obstructive pulmonary disease. The purpose of this study was to evaluate factors associated with occupational pulmonary function decline that can be used to create guidelines for the health management of shipyard workers Materials: This study analyzed spirometry from 10,597 male shipbuilding workers. Functional decline in spirometry was defined as FEV1/FVC <70% and logistic regression for work duration and occupational hazard exposure was performed Results: Among the subjects, 4.2% showed an obstructive pattern in pulmonary function. The odds ratios for hazard exposure were 1.67(indirect) and 3.54(direct), and for work duration 1.97(10-18 years), 2.29(19-27), and 5.02(28+). After adjusting for smoking and work-related factors, the odds ratios for work durations of over 10 years were 1.73(10-18 years), 1.99(19-27), and 4.09(28+), but for hazards exposure was 1.71(direct) alone after adjustment. Conclusions: Occupational COPD is insidious and chronic, and thus long-term hazard exposed(especially over 10 years) shipyard workers with functional decline in spirometry need to prevent and manage COPD. This study is important for establishing guidelines to manage hazard exposure among shipyard workers and prevent COPD.
