Background: Patients with chronic obstructive pulmonary disease (COPD) remain undiagnosed and potentially unknown until the more advanced stages of the disease. The rate of FEV1 decline was greater in patients with less severe disease than those with more severe disease. We aim to investigate the cost-effectiveness of inhaled treatment in early COPD. Methods: We reviewed the database of Korean adults recording less than 0.7 of FEV1/FVC from the Korean National Health and Nutritional Examination Survey (KNHANES) and Korean National Health Insurance (NHI) from 2007 to 2009. The early COPD was determined with more than 50% of FEV1. Results: 0f 1,919 patients who identified with early COPD in KNANES, 120 patients were confirmed that they visited hospital within the next year after diagnosis in NHI database. 58 (48%) patients were on inhaler for COPD. The others took oral medications. In patients using inhaler regularly, medical costs of outpatient clinic were significantly higher(P=0.012). However, totally medical costs including admission and emergency room were not different whether using inhaler or not. Multiple linear regression adjusting with age, sex, using inhaler, FEV1, income showed that smoking status was significant factors affecting the number of medical utilizations(β=4.26, P=0.008) and cost(β=658352, P=0.022). Conclusions: In early COPD patient, using inhaler did not cost more than taking the other type. The uncontrolled aggravating factors such as smoking increased directly medical costs in early COPD.

Liver Transplantation in Korea based on Big Data
( Jinkyeong Park ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1
Liver transplantation is the best and most common treatment for patients with end-stage liver disease. This mode of treatment gives the recipient a chance to have a new and almost normal liver, as well as freedom from previous disease. With the marked evolution in surgical and anaesthetic techniques, development of organ preservation solutions and advances in immunology, outcomes for liver transplantation have improved over time. As both knowledge and skills in this field develop, survival has increased, indications for transplantation have been broadened, and public awareness has been augmented with the hope of cure. However, great disparity exists between the need for liver organ grafts and available donors, such that waiting lists are growing and drop-out and mortality on waiting lists is increasing. After the first successful human liver transplantation in the world by Thomas E. Starzl in 1967, liver transplantation centres gradually increased in number; there are now liver transplantation centres throughout the world. As successes increased, worldwide acceptance followed and demand for liver transplantation was augmented as well; hence, the demand for liver transplantation increased exponentially with minimal increase in organ supply. To address this problem, Bismuth introduced the reduced-size graft in 1981. This innovation was followed by the introduction of the split-liver graft in 1988 by Pichlmayr. These methods helped alleviate some of the problems of organ shortage, but the continual demand for liver organ grafts remains and is increasing. The imbalance between organ supply and demand has prompted different solutions to prevent deaths from end-stage liver disease. The further advances in the field of LT in Korea requires unbiased and detailed information on the epidemiology of current LT in representative populations. The aim of this Study was thus to investigate the characteristics of LT recipients, as well as outcomes, in a comprehensive analysis of all LT recipients occurring in Korea in 2007-2015

The patients with chronic obstructive pulmonary disease (COPD) show various symptoms. In addition to breathlessness, cough and phlegm are the major symptoms. Although many clinical trials revealed that breathlessness is improved by inhaled therapy in COPD patients, the effect of these inhalers on cough or phlegm was not evaluated.The SUPER study demonstrated the improvement in lung function of the fluticasone/salmeterol (FSC) added to tiotropium statistically superior to that of tiotropium alone. We performed a post hoc analysis of the SUPER study with particular focus on cough and phlegm.At baseline, 89 (tiotropium +FSC vs tiotropium 22% vs 21%) patients complained that they suffered cough in most days a week. 106 (27% vs. 25%) patients did in a few days a week. 151 (38% vs 36%) patients did in only with chest infection. 134 (tiotropium +FSC vs tiotropium 33% vs 32%) patients complained that they suffered phlegm in most days a week. 126 (31% vs 30%) patients did in a few days a week. 101 (25% vs 25%) patients did in only with chest infection. At the end of study, 148(40% vs 32%) patients showed the improvement on cough, 190(43.1% vs 49.0%) patients had no change, and 74 (17% vs 19%) patients aggravated the cough. 42 (38% vs 31%) patients showed the improvement on phlegm, 76 (15% vs 22%) patients had no change, and 194 (47% vs 48%) patients aggravated the phlegm. In the patients suffered cough in most days a week at the baseline, tiotropium+FSC group had significantly more improvement in cough than tiotropium alone (76% vs 55%, p=0.047). There was no effect of phlegm between groups. In COPD patients presenting with cough, tiotropium combined FSC treatment was more helpful than tiotropium alone. However the effect of triple inhaled treatment about phlegm in COPD patients were similar to tiotropium alone.The patients with chronic obstructive pulmonary disease (COPD) show various symptoms.

Jinkyeong Jung,Hyunsook Yoon 한국응용언어학회 2010 응용 언어학 Vol.26 No.3
While there is a growing body of literature on the effects of teaching reading and writing together, there has not been much research on how reading preceded by writing affects reading comprehension, especially in the Korean context. The present study attempts to fill this research gap. 87 Korean university students who were divided into a control group and an experimental group participated in a reading class for TOEIC. The experimental group was engaged in writing tasks prior to reading comprehension tasks, while the control group was involved only in reading skills over 8 weeks. Both groups took the same pre- and post-reading tests and pre-writing test. The results show that performing writing tasks before reading comprehension tasks is a significant resource for improving college beginners’ reading skills, especially for low proficiency readers. Future research needs to be considered to uncover further practices and processes in connecting writing and reading in the Korean context.

The Influence of Asian Dust, Haze, Mist, and Fog on Hospital Visits for Airway Diseases
( Jinkyeong Park ),( Myoung Nam Lim ),( Yoonki Hong ),( Woo Jin Kim ) 대한결핵 및 호흡기학회 2015 Tuberculosis and Respiratory Diseases Vol.78 No.4
Background: Asian dust is known to have harmful effects on the respiratory system. Respiratory conditions are also influenced by environmental conditions regardless of the presence of pollutants. The same pollutant can have different effects on the airway when the air is dry compared with when it is humid. We investigated hospital visits for chronic obstructive pulmonary disease (COPD) and asthma in relation to the environmental conditions. Methods: We conducted a retrospective study using the Korean National Health Insurance Service claims database of patients who visited hospitals in Chuncheon between January 2006 and April 2012. Asian dust, haze, mist, and fog days were determined using reports from the Korea Meteorological Administration. Hospital visits for asthma or COPD on the index days were compared with the comparison days. We used two-way case-crossover techniques with one to two matching. Results: The mean hospital visits for asthma and COPD were 59.37 ± 34.01 and 10.04 ± 6.18 per day, respectively. Hospital visits for asthma significantly increased at lag0 and lag1 for Asian dust (relative risk [RR], 1.10; 95% confidence interval [CI], 1.01-1.19; p<0.05) and haze (RR, 1.13; 95% CI, 1.06-1.22; p<0.05), but were significantly lower on misty (RR, 0.89; 95% CI, 0.80-0.99; p<0.05) and foggy (RR, 0.89; 95% CI, 0.84-0.93; p<0.05) days than on control days. The hospital visits for COPD also significantly increased on days with Asian dust (RR, 1.29; 95% CI, 1.05-1.59; p<0.05), and were significantly lower at lag4 for foggy days, compared with days without fog (RR, 0.85; 95% CI, 0.75-0.97; p<0.05). Conclusion: Asian dust showed an association with airway diseases and had effects for several days after the exposure. In contrast to Asian dust, mist and fog, which occur in humid air conditions, showed the opposite effects on airway diseases, after adjusting to the pollutants. It would require more research to investigate the effects of various air conditions on airway diseases.
