The subject study was targeted towards nutrition teacher (dietitian) of elementary, middle, and high schools in Seoul areal. In addition, this study was to investigate the current status of school foodservice securement facilities & equipments and to analyze the obstructive factors for executing the HACCP system. The aim of this study was to provide base-line data so that a more efficient & effective sanitary management system for school foodservise can be settled in. All surveys were distributed and collected via email. A total of 305 survey papers were collected and out of these, 300 school results were analyzed and the results are as follows. The order of the securement facilities & equipment furnished were pre-handing equipments>washing>cooking>inspection>facilities>storage>space area>distribution equipments. The awareness of obstructive factors in executing the HACCP system was a total of 3.17 points and the order was as follows. The general obstructive factors>obstructive factors in the cooking staff executing the HACCP system>collaboration between the school/team leaders and the budget supporting department>obstructive factors in the nutrition teacher (dietitian) executing the HACCP system. School foodservice securement facilities & equipments in Seoul area must be renovated and modernized so as to improve its current situation. Furthermore, leadership programs are necessary to enhance nutritionists' understanding of the HACCP system and the cooking staff's competencies in instructing and supervising.

Purpose: The purpose of the present study is to examine risk factors for unawareness of obstructive airflow limitation among adults with chronic obstructive pulmonary disease. Methods: Secondary data analysis was performed with the data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES; 2013-2014). The data were analyzed with the IBM SPSS 22.0 version using frequency, percentage, odds ratio, and logistic regression. Results: Ninety-eight percent of subject with a pulmonary function test score of $FEV_1/FVC$<0.7 (N=833) did not recognize that their lung function was impaired. The heavy drink, absence of tuberculosis or asthma diagnosis, and no symptom of expelling phlegm were identified as major risk factors for unawareness of airflow limitation. Conclusion: In order to increase awareness of airflow limitation and to prevent the worsening of the condition, the pulmonary function screening test should be provided to community residents including those who do not show symptoms of respiratory illness.

Purpose: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease. Methods: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital. Data was collected from June to October, 2005 using structured questionnaires, an oxygen saturation test, a 6-minute walking test, and a pulmonary function test. Results: Subjects had a slightly low degree of fatigue. The fatigue showed a significant correlation with emotion(r=.589, p= .000), dyspnea(r=.304, p= .001), self-efficacy(r=-.278, p= .002), and symptom experience(r=.238, p= .008). Emotion(34.7%) and dyspnea(5.8%) were significant predictors to explain fatigue. Conclusion: This study provides comprehensive understanding of the influencing factors on fatigue in patients with chronic obstructive pulmonary disease. Nursing interventions to decrease negative emotion and dyspnea for management of fatigue is suggested.

Chronic obstructive pulmonary disease (COPD) is a common airway disease that has considerable impact on disease burdens and mortality rates. A large number of articles on COPD are published within the last few years. Many aspects on COPD ranging from risk factors to management have continued to be fertile fields of investigation. This review summarizes 6 clinical articles with regards to the risk factors, phenotype, assessment, exacerbation, management and prognosis of patients with COPD which were being published last year in major medical journals.

The pathogenesis and mechanism of obstructive sleep apnea (OSA) has been under investigation for over 25 years, but its etiology and mechanism remains elusive. Skeletal (maxillary and/or mandibular hypoplasia or retrodisplacement, inferior displacement of hyoid) and soft tissue (increased volume of soft tissue, adenotonsillar hypertrophy, macroglossia, thickened lateral pharyngeal walls) factors, pharyngeal compliance (increased), pharyngeal muscle factors (impaired strength and endurance of pharyngeal dilators and fixators), sensory factors (impaired mechanoreceptor sensitivity, impaired pharyngeal dilator reflexes), respiratory control system factors (unstable respiratory control) and so on facilitate collapse upper airway. Therefore, OSA may be a heterogeneous disorder, rather than a single disease entity and various pathogenic factors contribute to the OSA varies person to person. As a result, patients may respond to different therapeutic approaches based on the predominant abnormality leading to the sleep-disordered breathing.

최근 미세먼지 농도가 올라감에 따라 사람들은 호흡기 질환에 큰 관심을 가지고 있다. 본 연구는 인구학적 및 임상적 특징을 통한 만성 폐쇄성 폐질환(chronic obstructive pulmonary disease)의 위험요인을 선별하고 이에 따른 노모그램을 구축하였다. 먼저 국민건강영양조사(KNHANES) 6기 (2013-2015)의 인구학적 및 임상적 특징, 폐기능 검사 결과를 사용하여 로지스틱 회귀분석을 실시 하였고 비전공자들도 분석 결과에 대한 해석을 쉽게 할 수 있도록 만성 폐쇄성폐질환의 위험 요 인을 시각화한 노모그램을 구축하였다. 또한 ROC curve와 Calibration plot을 이용하여 만성 폐쇄 성 폐질환의 노모그램을 검증하였다.

노모그램은 질병의 위험 요인과 예측 확률을 쉽게 이해할 수 있도록 시각적으로 표현하는 통계적 도구이다. 본 논문은 만성 폐쇄성 폐질환(chronic obstructive pulmonary disease)의 위험 요인을 이용하여 로지스틱 회귀모형과 순수 베이지안 분류기 모형의 노모그램을 구축하고 이를 비교하였다. 분석 데이터는 국민건강영양조사 6기(2013-2015)를 이용하여 진행하였다. 총 6개의 위험 요인을 이용하였다. 그리고 로지스틱 회귀모형, 순수 베이지안 분류기 모형과 각각의 구축 방법을 이용하여 만성 폐쇄성 폐질환의 노모그램을 제시하였다. 또한, 구축된 두 노모그램을 비교하여 유용성을 살펴보았다. 마지막으로 ROC curve와 Calibration plot을 통하여 각 노모그램을 검증하였다.

The purpose of this study was to report and discuss the diagnosis and treatment of obstructive atelectasis secondary to pus obstruction in a patient who had developed a maxillofacial abscess, and to review the literature on similar cases. Persistently discharging pus within the oral cavity can act as an aspirate, and may lead to obstructive atelectasis. Additionally, maxillofacial surgery patients should be carefully assessed for the presence of risk factors of obstructive atelectasis, such as, epistaxis after nasotracheal intubation, oral bleeding, and mucus secretion. Furthermore, patients with these risk factors should be continuously followed up by monitoring $SPO_2$, breath sounds, and chest x-ray.

본 연구는 성인 만성폐쇄성폐질환(Chronic Obstructive Pulmonary Disease, COPD) 환자의 인플루엔자 접종률과 접종에 영향을 미치는 요인을 파악하기 시행하였다. 2014년부터 2018년까지 5년간의 국민건강영양조사에 참여한 대상자 중 만 40세 이상이며 폐기능 검사 판정결과 폐쇄성환기장애(FEV1/FVC<0.7)로 나타난 2,370명을 대상으로 인플루엔자 예방접종률과 접종에 미치는 영향요인을 분석하였다. 민간강영양조사 데이터를 분석한 결과 만 40세 이상 성인 COPD 환자의 인플루엔자 예방접종률은 59.2%이었으며, 예방접종에 영향을 미치는 요인은 65세 이상, 낮은 경제수준, 과거흡연자이거나 비흡연자, 최근 2년 이내 건강검진을 받은 경우이었다. COPD가 있는 성인의 예방접종률을 높이기 위하여 인플루엔자 예방접종에 영향을 주는 요인들을 고려하여 예방접종률을 높이기 위한 방안을 모색해야 할 것이다.

Background: Chronic obstructive pulmonary disease (COPD) is sometimes complicated with pneumonia, but little is known about the risk factors that promote the development of pneumonia in COPD. These risk factors were evaluated in the present study. Methods: The data of 324 patients with COPD from a prospective multi-center observational cohort with obstructive lung disease were evaluated retrospectively. To identify risk factors for the development of pneumonia in COPD, the clinical and radiological data at enrollment and the time to the first episode of pneumonia were analyzed by Cox proportional hazard analysis. Results: The median follow-up time was 1,099 days and 28 patients (8.6%) developed pneumonia. The Cox analysis showed that post-bronchodilator forced expiratory volume in one second ($FEV_1$, % of predicted) and the computed tomography (CT) emphysema extent (inspiratory V950) were independent risk factors for the development of pneumonia (post-bronchodilator $FEV_1$: hazard ratio [HR], 0.97; 95% confidence interval [CI], 0.94-1.00; p=0.048 and inspiratory V950: HR, 1.04; 95% CI, 1.01-1.07; p=0.01). Conclusion: Emphysema severity measured by CT and post-bronchodilator $FEV_1$ are important risk factors for the development of pneumonia in COPD.
