Burden of disease analysis provides a unique perspective on health by integrating fatal and non-fatal outcomes, yet allows the outcome of two classes to be examined separately. Although many studies have shown the inequality in health outcomes across socioeconomic status (SES), an analysis and comparison of Disability Adjusted Life Year (DALY) between different socioeconomic groups has been rare. This paper calculates the DALY and analyzes the distribution of DALYs for different SES. This study draws from 3,278 cases from the survey on "The Livelihood and Welfare Needs of the Elderly (2004)". It first provides a comprehensive assessment of the burden of 10 chronic diseases of the elderly based on DALY. Then this paper analyzes inequalities in the burden of disease by the levels of SES such as education, income, family size, occupation, and subjective economic conditions. For the elderly, the burden of disease is the highest for hypertension, arthritis and cancer. DALY rate per 1,000 people for the most socio-economically disadvantaged group is expressed as a multiple of the standardized rate for the least disadvantaged group (Rate Ratios). Family size is strongly related to. the difference in the burden of disease between SES groups, and the elderly Who live alone have higher DALY rate than those who live with their family. Other significant variables related to SES groups include subjective economic conditions, occupation, elderly income, and household income.

At the preliminary survey of Seosan demonstration project for integration of family planning and maternal and child health service, 6 questions about morbid conditions of all household members were included. Definition of morbid condition used at the survey was self-conceived physical or mental infirmity which had been caused by diseases or accidents, resulting in obstacles to ordinary daily life for past 30 days. Analyzing those morbidity data, the following results were obtained. 1. The morbid person rate was 192.2 per 1,000 persons and the morbidity rate 214.2 per 1,000 persons. 2. The percentage of household which had at least one morbid person was 61.9% and average number of morbidity per one household was 1.1. 3. Analyzing the 1st morbid condition of the total 4,433 morbid persons, morbidity rate of male was 194.6 per 1,000 persons and that of female was 189.8 per 1,000 persons. 4. The highest age specific morbidity rate was that of $0{\sim}4$ years of age, and it was 304.3 per 1,000 persons. The lowest was that of $10{\sim}14$ years of age and the rate of 93.8 per 1,000 persons. 5. The following was the order of five major diseases which were classified according to 17 International Classification of Diseases. (1) Symptoms and Ill defined conditions : 17.3% (2) Disease of the Digestive system : 15.7% (3) Infections and Parasitic disease 14.3% (4) Disease of the Respiratory system : 13.7% (5) Disease of the Nervous system and sense organs : 9.4% 6. 30 leading morbid conditions were described in Table III-2 and which composed 70.6% of total morbid conditions. 7. The percentage of the morbid conditions of which duration was longer than 90 days was 40.5%. 8. Of the total 4,433 morbid persons, 4,394 morbid persons responded for the morbid condition management method. Of those, Hospital & clinic (35.3%), drug store (40.0%), herb drug store (3.6%), health center (2.2%) ware selected for the 1st place or method for management morbid condition, and 18.0% did not search for morbid condition management.

Platycodon grandiflorum and Codonopsis lanceolata have been considered as cash vegetables and alternative medicine plants in Korea. In a previous survey from 1998 to 2010, repeated cultivation of the plant increased root rot disease incidence and severity. The disease has been recognized as critically limiting factor for crop production. However, control method has not been established for the disease of P. grandiflorum and C. lanceolata. In this study, control efficacy of Tebuconazole EC, Trifloxystroim SC and grapefriut extract was evaluated on the root rot disease of these plants in two different field conditions. Three of different fungicide were non critical effect to the disease severity and the control value, but grapefriut seed extract (GSE) was more ability to control the disease in C. lanceolata. In most things, soil drainage was the most important to decrease the disease severity and to improve the control value.

Weather data for disease forecasts are usually derived from automated weather stations (AWS) that may be dispersed across a region in an irregular pattern. We have developed an alternative method to simulate local scale, high-resolution weather and plant disease in a grid pattern. The system incorporates a simplified mesoscale boundary layer model, LAWSS, for estimating local conditions such as air temperature and relative humidity. It also integrates special models for estimating of surface wetness duration and disease forecasts, such as the grapevine downy mildew forecast model, DMCast. The system can recreate weather forecasts utilizing the NCEP/NCAR reanalysis database, which contains over 57 years of archived and corrected global upper air conditions. The highest horizontal resolution of 0.150 km was achieved by running 5-step nested child grids inside coarse mother grids. Over the Finger Lakes and Chautauqua Lake regions of New York State, the system simulated three growing seasons for estimating the risk of grape downy mildew with 1 km resolution. Outputs were represented as regional maps or as site-specific graphs. The highest resolutions were achieved over North America, but the system is functional for any global location. The system is expected to be a powerful tool for site selection and reanalysis of historical plant disease epidemics.

Effect of potassium phosphonate on control of potato late blight was evaluated at two fields in Jeju island. The chemical showed 82.5% control value in field located at low seacoast with 100 m elevation, while dimethomorph copper oxychloride showed 75.9 % control value. However, its control value was only 40% in another field located at mid-hilly area with 300 m elevation, in which environmental conditions of high hummudity and often rainfall were favorable to the disease development. Application intervals of the phosphonate from 7 to 15 effectively suppressed the disease and did not show statistically different control values among the spraying intervals. Results indicated that phosphonate similarly or more effectively controls potato late blight than fungicide, however, its control value could be vared according to enviromental conditions for the disease development and 15-d spraying intervals ware sufficient to suppress ther disease.

Pig chronic wasting disease, including porcine reproductive and respiratory syndrome (PRRS) and postweaning multisystemic wasting syndrome (PMWS), have made a continuous economic damage in pig farms. Airborne spread of livestock viruses are an important spread factor which is difficult to analyze due to invisible airflow and limitation of measurement. The objective of this study is to analyze airborne disease spread between buildings in the experimental pig farm by means of field experiment and computational fluid dynamics (CFD). The field experiments were conducted to capture airborne virus using air sampler and teflon filter along multi points in the experimental pig farm. The samples were tested in terms of virus detection resulting in positive reaction for PRRS and PCV-2 viruses, which can be a firm evidence of airborne virus spread. The CFD simulation model was developed by considering complex topography, wind conditions, building arrangement, and ventilation systems and was used to analyze airborne virus spread according to different wind conditions. The CFD computed result showed a possibility of airborne virus spread via livestock aerosol from infected pig house to neighboring pig houses according to wind directions. The CFD simulation technique is expected to provide significant data for estimating and making a counterplan against airborne disease spread.

Moyamoya-like vasculopathy develops in association with various systemic diseases and conditions, which is termed moyamoya syndrome. Relatively common diseases and conditions are related to moyamoya syndrome, including neurofibromatosis type 1, Down syndrome, thyroid disease, and cranial irradiation. Moyamoya syndrome shares phenotypical characteristics with idiopathic moyamoya disease. However, they differ in other details, including clinical presentations, natural history, and treatment considerations. The study of moyamoya syndrome can provide clinicians and researchers with valuable knowledge and insight. Although it is infrequently encountered in clinical practice, moyamoya-like vasculopathy can severely complicate outcomes for patients with various underlying diseases when the clinician fails to expect or diagnose moyamoya syndrome development. Furthermore, moyamoya syndrome could be used as a doorway to more enigmatic moyamoya disease in research. More comprehensive survey and investigation are required to uncover the secrets of all the moyamoya-like phenomena.

Purpose: The purpose of the present study was to explore the meaning of quality of life in patients with chronic cardiovascular disease. Methods: A grounded theory method guided data collection and analysis. A total of 16 adult outpatients with chronic cardiovascular disease was participated. Data were collected through individual in-depth interviews. All interviews were audio taped and transcribed verbatim. Coding was used to establish different concepts and categories. A theoretical sampling technique was used to obtain diverse data from many relevant categories. Results: Seven categories were extracted, and they divided into constructing and intervening factors of quality of life. Constructing factors were uncertainty, recovery in the sense of control and maintaining social life. Intervening factors were symptom experiences, social support, taking care of themselves, and reflecting life. 'Keeping restrictive conditions under control' was emerged as a core category. The meaning of quality of life in patients with cardiovascular was explained according to the levels of keeping restrictive conditions under control. Conclusion: The result of this study may contribute for health professionals to understand the quality of life in patients with cardiovascular disease.

The disease concept of interstitial lung disease with idiopathic pulmonary fibrosis at its core has been relied on for many years depending on morphological classification. The separation of non-specific interstitial pneumonia with a relatively good prognosis from usual interstitial pneumonia is also based on the perception that morphology enables predict the prognosis. Beginning with dust-exposed lungs, initially, interstitial pneumonia is classified by anatomical pathology. Diagnostic imaging has dramatically improved the diagnostic technology for surviving patients through the introduction of high-resolution computed tomography scan. And now, with the introduction of therapeutics, the direction of diagnosis is turning. It can be broadly classified into to make known the importance of early diagnosis, and to understand the importance of predicting the speed of progression/deterioration of pathological conditions. For this reason, the insight of "early lesions" has been discussed. There are reports that the presence or absence of interstitial lung abnormalities affects the prognosis. Searching for a biomarker is another prognostic indicator search. However, as is the case with many chronic diseases, pathological conditions that progress linearly are extremely rare. Rather, it progresses while changing in response to environmental factors. In interstitial lung disease, deterioration of respiratory functions most closely reflect prognosis. Treatment is determined by combining dynamic indicators as faithful indicators of restrictive impairments. Reconsidering the history being classified under the disease concept, the need to reorganize treatment targets based on common pathological phenotype is under discussed. What is the disease concept? That aspect changes with the discussion of improving prognosis.

The coronavirus pandemic, known as coronavirus disease 2019 (COVID-19), is an infectious respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus first identified in patients from Wuhan, China. Since December 2019, SARS-CoV-2 has spread swiftly around the world, infected more than 25 million people, and caused more than 800,000 deaths in 188 countries. Chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD) appear to be risk factors for COVID-19, however, their prevalence remains controversial. In fact, studies in China reported lower rates of chronic respiratory conditions in patients with COVID-19 than in the general population, while the trend is reversed in the United States and Europe. Although the underlying molecular mechanisms of a possible interaction between COVID-19 and chronic respiratory diseases remain unknown, some observations can help to elucidate them. Indeed, physiological changes, immune response, or medications used against SARS-CoV-2 may have a greater impact on patients with chronic respiratory conditions already debilitated by chronic inflammation, dyspnea, and the use of immunosuppressant drugs like corticosteroids. In this review, we discuss importance and the impact of COVID-19 on asthma and COPD patients, the possible available treatments, and patient management during the pandemic.
