Chronic obstructive pulmonary disease (COPD) results in high morbidity and mortality among patients both domestically and globally. The Korean clinical practice guideline for COPD was revised in 2014. It was drafted by the members of the Korean Academy of Tuberculosis and Respiratory Diseases, as well as participating members of the Health Insurance Review and Assessment Service, Korean Physicians' Association, and Korea Respiration Trouble Association. This revised guideline covers a wide range of topics, including the epidemiology, diagnosis, assessment, monitoring, management, exacerbation, and comorbidities of COPD in Korea. We drafted a guideline on COPD management by performing systematic reviews on the topic of management with the help of a meta-analysis expert. We expect this guideline will be helpful medical doctors treating patients with respiratory conditions, other health care professionals, and government personnel in South Korea.

Bone is a common site for metastatic spread from many kinds of malignancies. The morbidity associated with this metastatic spread can be significant, including severe pain. When it comes to spinal metastasis, occupying nearly 40% of skeletal metastases, the risks of complications, such as vertebral body collapse, nerve root impingement, or spinal cord compression, are also significant. Because of the necessity of preserving the integrity of the spinal column and the proximity of critical structures, surgical treatment has limitations when durable local control is desired. Radiotherapy, therefore, is often used as an adjunct treatment or as a sole treatment. A considerable limitation of standard radiotherapy is the reported recurrence rate or ineffective palliation of pain, either clinically or symptomatically. This may be due to limited radiation doses to tumor itself because of the proximity of critical structures. CyberKnife is an image-guided robotic radiosurgical system. The image guidance system includes a kilovoltage X-ray imaging source and amorphous silica detectors. The radiation delivery device is a mobile X-band linear accelerator (6 MV) mounted on a robotic arm. Highly conformal fields and hypofractionated radiotherapy schedules are increasingly being used as a means to achieve biologic dose escalation for body tumors. Therefore, we can give much higher doses to the targeted tumor volume with minimizing doses to the surrounding critical structures, resulting in more effective local control and less severe side effects, compared to conventional fractionated radiotherapy. A description of this technology and a review of clinical applications to bone metastases are detailed herein.

Purpose: The purpose of this study was to identify the attributes, antecedents, and consequences of post-intensive care syndrome. Methods: The study was conducted in accordance with Walker and Avant's conceptual analysis process. We searched the Medline, ProQuest, Google scholar, NANET (Korean National Assembly Library), and RISS (Korean Education and Research Information Service) databases resulting in 29 studies for in-depth review. Results: The attributes of post-intensive care syndrome include (1) new or worsening impairment persisting after discharge, (2) physical impairment, (3) psychological impairment, (4) cognitive impairment, and (5) symptom experience. The antecedents of the concept include a critical condition that requires intensive care, stressful events, immobility, sedation, delirium, insomnia, frailty, and invasive procedures. The consequences of post-intensive care syndrome are increased dependency in activities of daily life, decreased social interaction, delayed return to previous occupation, decreased quality of life, familial post-intensive care syndrome, and readmission/death. Conclusion: The concept of post-intensive care syndrome has multifaceted and integrative features. Further research needs to be conducted to develop a measurement tool that reflects the attributes of the concept and to develop multidisciplinary interventions to prevent post-intensive care syndrome.

Library and information science(LIS) research has been dominated by functionalistic orientation as one of the postulates of positivism. As a result, it has often been criticized that LIS research does not take into account the social, cultural, political, and economic contexts on which the theories and the practices of LIS are based. In this regard, this paper seeks to establish and apply critical inquiry through a review of the relevant aspects of critical theory and application of those insights to current research and practice in LIS. Connections of LIS research to relevant political, social and economic issues are particularly stressed.

Purpose : This study aims to develop the Forensic Nursing Competency Scale suitable to South Korea. Methods : The initial items were generated through literature review and interviews. Items were evaluated by experts for content and face validity. By conducting a pilot test, 74 measurement items were developed. In total, 333 copies of the questionnaire were analyzed regarding the validity and reliability of the study. Data were analyzed using SPSS 23.0 program and AMOS 18.0 program. Results : The study selected 53 questions after testing the content, face, and construct validity of the scale. The final 53 questions were composed of 15 sub-components in eight domains. These eight domains encompassed nursing practice, communication, critical thinking, human caring and relationships, evidence management, active information collection, professional development, and knowledge integration. Conclusions : In order to verify the effectiveness of the scale, future studies need to compare the forensic nursing competency in two groups to assess differences in these competency. Moreover, it is necessary to develop a forensic nursing educational program and validate its effectiveness by using this scale.

With a focus on different aspects of PMIS in construction projects, various sets of critical success factors (CSFs) have been suggested in the literature such as IS Success Model by various researchers. It is crucial to explore the relative importance and groupings of these factors. This paper aims to identify CSFs associated with Project Management Information System (PMIS) in construction projects, and explore their ranking and underlying relationship. CSFs for PMIS identified through a literature review, and consolidated by interviews and pilot studies with professionals in construction industry. A questionnaire instrument was sent out to experienced users (Construction Manager and Constructor) in Korea, and 253 completed questionnaires were retrieved. To increase the generalizability of the results, the respondents were spread across construction site. Using factor analysis and considering the high importance of the factor, CSFs were grouped into three dimensions. All these three groupings and their relationship were included in a framework for successful PMIS in construction projects. These findings help to clarify what the high prioritized factors are, and could also be used as an assessment tool to evaluate the performance of PMIS and thus help to identify areas for improvement.

The purpose of this study would like to investigate the critical success factors of the e-procurement which means on-line purchase of goods and services for organizations. This action represents one of the largest expense items in a firm's cost structure. In order to draw CSFs of e-procurement system, we have surveyed questionnaire to the related firms. The basic variables used in this survey are taken from many precedent researches in relation to the e-procurement. On the other hand, the research data is collected from companies which had used the MRO e-marketplace. Through factor analysis of those data, four-factor resulted as follows: (1) factor one suggests the rationalization of the firm's management of its suppliers; (2) factor two calls for redesigning affected business processes and influencing end-user/employee procurement-related behaviors; (3) factor three refers to carefully orchestrating an e-procurement technology planning process with one's suppliers and using intelligence in designing the software and mining the data it produces; and (4) factor four relates to selecting an e-procurement solution and/or simultaneously participating in a number of electronic environments supporting e-procurement. In conclusion, these four factors are regarded as critical success factors for the application of e-procurement system and then suppliers should take care the effective planning of e-procurement structure.

Extracorporeal Membrane Oxygenation (ECMO) support to tissue oxygenation has been shown to improve survival in patients with life threatening respiratory distress syndrome or cardiac failure. Extracorporeal life support such as ECMO, including extracorporeal $CO_2$ removal ($ECCO_2R$), is used as temporary support until successful recovery of organs. A recently published multicentre randomized controlled trial, known as the CESAR (conventional ventilation or extracorporeal membrane oxygenation for severe adult respiratory failure) trial, was the first trial to demonstrate the utility of ECMO in acute respiratory distress syndrome (ARDS). During the 2009 influenza A (H1N1) pandemic, there were many reports of patients with severe ARDS related to H1N1 infection treated with ECMO. These reports revealed a high survival rate and effectiveness of ECMO. In this review, we explain the indication of ECMO clinical application, the practical types of ECMO, and complications associated with ECMO. In addition, we explain recent new ECMO technology and management of patients during ECMO support.
