Background : In 1980, WHO made a definition in which the term "impairment" as applied to the respiratory system is used to describe loss of lung function, "disability" the resulting diminution in exercise capacity. The measurement of pulmonary function during exercise would give us information about overall functional capacity and respiratory performance that would be lacking in tests performed at rest. We conducted this study to investigate the role of resting pulmonary function test and exercise test for assessing impairment/disability in patients with chronic airflow obstruction(CAO). Method : We studied 19 patients with CAO. The spirometry and body plethysmograph were performed in stable condition. And then patients performed a progressive incremental exercise test to a symptom-limited maximum using cycle ergometer. Patients were divided in two groups, severe and non-severe impairment, according to the resting PFTs and compaired each other. A patient was considered to be severely impaired if FVC < 50 %, FEV1 < 40 % or FEV1/FVC < 40 %. Results : 1) The airway obstruction and hypoxemia of severe impairment group were more severe and exercise performance was markedly reduced compairing to non-severe impairment group. 2) The severe impairment group showed ventilatory limitation during exercise test and the limiting symptomes ware dyspnea in 9/10 patients. 3) The impairment and disability of the patients with tuberculous destructed lung were most marked in patients with CAO. 4) The FEV1 was the most prevalent criterion for the determination of severe impairment based on resting PFTs and was the valuable best correlated to V02max(r=0.81, p < 0.001). 5) The sensitivity of exercise limits for predicting severe disability according to resting PFTs was 80 % and specificity 89 %. Conclusion : In patients with severe CAO, FEV1 is a good predictive of exercise performance and impairment measured by resting PFTs can predict a disability by exercise test.

Destruction appraisal system improved with the enactment of the 1999 Public Records Management Act has the strategic concepts to prevent loss of important records with prohibiting the destruction in creation organization of records. But destruction appraisal carried out in record center realistically has the big difference with destruction appraisal system intended by Public Records Management Act. Therefore this article intends to explore the importance of destruction appraisal system through a review of the record appraisal system, and investigates operation status of destruction appraisal system in record center and operational issues. And it intends to explore scheme for practical application of destruction appraisal system based on actual cases of destruction appraisal which operates as a model.

Lung volume reduction surgery(LVRS) has recently been advocated as an alternative or a bridge to lung transplantation for patients with evere dibbling emphysema. This procedure is a palliative treatment performed to alleviate the dyspnea of patients with emphysema and improve performance in the activities of daily living. The rationale of lung volume reduction for generalized emphysema is that the removing of the diseased and functionless lung may improve the function of remaining, less diseased lung. The factors critical to the success of LVRS are careful patient selection, accurate localization of target areas, meticulous anesthetic and operative technique, and intensive postoperative support. We have experienced a case of severe emphysema in a 59-year-old male patient. After selection process and pulmonary rehabilitation, the patient was treated with video-assisted thoracoscopic LVRS and the post-operative course was uneventful.

This study aims to suggest the basis and criterion for the data deletion guideline to make the information systems effective and reduce the cost of system management. To make a frame of the guideline, we researched the laws and policies of USA, UK and Australia and the domestic laws and regulations related with the deletion of records. From this paper research, we prepared the draft guideline and gathered the opinion about it. Through this research and survey, we produced out the guideline including the criteria, the process and the way of data deletion. Adopting the guideline to a sample organization, we couldn't find any problem in deleting the unused data.

Background : The effects of chemotherapy on pulmonary function are mainly a reduced diffusion capacity and a restrictive ventilatory impairment. Exercise can expose cardiovascular and pulmonary abnormalities not evident at rest. Exercise related cardiopulmonary function is important in patients with malignant disease as a determinant of quality of life. We performed this study to evaluate the changes of body composition and cadiopulmonary exercise perfoemance of patients with locally advanced, non-small cell, lung cancer (NSCLC) before and after chemotherapy. Methods : We evaluated resting pulmonary function, body composition, physiologic performance status, and cardiopulmonary exercise function in 11 patients with locally advanced NSCLC, at diagnosis and prior to the fourth cycle of chemotherapy. Results : After chemotherapy, 4 patients (36.4%) showed partial response and 7 (63.4%) had stable disease. After chemotherapy, diffusion capacity of the lung for carbon monoxide was reduced ($89.7{\pm}34.1%$, vs. $71.9{\pm}20.5%$) but not significantly. There were no significant changes in body composition or the state of physiologic performance after chemotherapy. There was a significant impairment of cardiopulmonary exercise tolerance in patients with NSCLC, evidenced by a reduction of maximal oxygen uptake ($VO_2$max, ml/kg/min, $17.9{\pm}2.6$ : $12.6{\pm}6.1$, <0.05) and $O_2$pulse ($O_2$ pulse, ml/beat, $7.0{\pm}1.7$, $5.2{\pm}2.1$, <0.05). Conclusion : Systemic chemotherapy resulted in a loss of cardiopulmonary exercise function in patients with locally advanced NSCLC within the short-term period, but not a physiologic change of body composition within the same period.

The Records Disposal Freeze Program will be introduced in June 2020 with the revision of the Public Records Act of South Korea. In the study, the issues of the program were identified through the analysis of domestic cases and the programs of other countries, and the improvement plans on the issues were suggested. For the analysis of the programs, seven factors which should be presented to implement the program were derived from the notices of disposal freeze by National Archives of Australia. Based on the factors, the programs were analyzed; the programs of South Korea, the United States of America, United Kingdom, Australia and New Zealand. As a result of analysis and comparison of the programs, five issues of Korean program were derived. The experts interviews were conducted to understand the perception and the perspective on the program of records managers and archivists. The improvement plans for the program of South Korea were suggested based on the analysis and comparison of the programs of five countries and experts interviews.
