Background: Tracheobronchial suctioning using the closed suctioning system has physiological benefits for critically ill patients. Despite these benefits, there are concerns about increased colonization of tracheobronchial tree by pathogenic organisms. The cost is another hinder to the introduction of closed suction system. The aim of this study was to evaluate the incidence of colonization and ventilator associated pneumonia and the cost-effectiveness of closed suction compared with open suction. Methods: During separated one month period, patients admitted MICU were cared by multiple-use, open suction, single-use, open suction and multiple-use, closed suction method, consecutively. Costs, colonization of tracheobronchial tree by MRSA and the incidence of ventilator-associated pneumonia (VAP) were analyzed. Results: One-hundred and six patients were enrolled. Twenty patients were treated with multiple-use, open suction, while 42 and 44 patients were cared with single-use, open catheter and multiple-use, closed catheter, respectively. Colonization by MRSA and the incidence of VAP were not different among three ways of suctioning. The overall costs per patient per day for suctioning were $10.58 for multiple-use, open suction, $28.27 for single-use, open suction and $23.76 for multiple-use, closed suction. Conclusion: Multiple-use, closed suctioning, when suction catheters were changed every 48 hrs, has the similar incidence of colonization of MRSA and occurrence of VAP and is a cost-efficient way of endotracheal suction.

Customer retention is one of the major issues in life insurance industry, in which competition is increasingly fierce. There are many things for the life insurers to do many things to retain the customers. One of those things is to make sure to keep in touch with all customers. When an insurance-planner resigned, his/her customers must be taken care of by some planner-assistants. This article outlines the design of Contact Scheduling System (CSS) that supports planner-assistants for contacting the customers. Planner-assistants are unable to share the resigned insurance-planner's experience and knowledge regarding the customer relationship management. The CSS developed by employing both Classification And Regression Tree (CART) technique and Sequential Pattern Mining (SPM) technique has a two-stage process. In the first stage, it segments the customers into eight groups by CART model. Then it generates contact scheduling information consisting of contact-purpose, contact-interval and contact-channel, according to the segment's typical contact pattern. Contact-purpose is derived by schedule-driven, event-driven, or business-rule-driven. Schedule-driven contact is determined by SPM model. In the operation of CSS in a realistic situation, it shows a practicality in supporting planner-assistants to keep in touch with the customers efficiently and effectively.

Purpose: This exploratory study was to identify the use of complementary and alternative medicine(CAM) in women with breast cancer and to analyze which factor influence CAM use. Methods: 114 patients with breast cancer were identified and approached. The instrument used to gather data were the common types, main reasons and effects as well as stress, mood states and fatigue. Results: 42.7% of all participants reported the use of CAM. The most common types of CAM used were Phellinus linteus, elm tree, and vitamin C. The main reasons for CAM use were to boost the immune system and to prevent recurrence. Prayer, massage, Shitake mushroom, and Ganoderma lucidum were, identified as being more effective than others. 93.6% of the respondents informed their physicians of their use of CAM. Logistic regression analysis determined that stress, mood states, and duration after diagnosis were factors significantly associated with CAM use. Conclusion: CAM use is increasing among patients with breast cancer. Health care professionals are in the main position to identify what treatments patients are using and implement CAM therapies that can be helpful to relieve patient symptoms related to treatment and psychological distress.

Recently the Supreme Court held that "in cases in which a patient suffering from a mental disorder attempts to commit suicide, fails, and then succeeds in a subsequent attempt, the following circumstances must be present in order to acknowledge reasonable causation between the negligence of the hospital with regards to taking care of the patient and the death of the patient; there must have existed negligence on the part of the hospital with regards to their failure to stop the 1stsuicide attempt, injurious aftereffects must have been caused to the patient by the1stsuicide attempt, and said aftereffects must have been the main cause for the 2nd successful suicide attemtp." This, in effect, lessens the requirements of past holdings of the Supreme Court which held that "to acknowledge reasonable causation between the negligence of the hospital and the patient that commits suicide, the patient must have experienced such severe physical and mental suffering from the previous attempt so that they could not help but choose to commit suicide". The fact that the Supreme Court did not clearly state such changes in their view on this matter should be corrected. Also, the fact that the court only held the hospital liable for damages of less than 50 million won, only calculating damages up to the point when the deceased passed, is inadequate compared to other cases and should be corrected.

Living systems constantly suffer from atmospheric reactive oxygen species and also produce inevitably them by the course of metabolism. Therefore, antioxidants play important roles in protecting the systems from various diseased caused by them. In this study, we investigated various tinged autumnal leaves as antioxidant sources. Among the, the red leaf extracts of Acer Palmatum THUNBERG.(Aceraceae: maple tree) and Prunus Donarioum Sieb. Var. spontanea Makino(Rosaceae : cherry trees) showed the highest anti-oxidativities. The major antioxidants in their red leaves were isolated and identified as vitexin from maple leaves and isoscutellarein-4'-O-$\beta$-glucopyranoside from cherry leaves. Finally, we evaluated the efficacy of skin care products containing the extracts by human use study. As a result, the tinged leaves of maple and cherry trees were evaluated as good antioxidant sources on the bases of antioxidativities, cytotoxicities, cell proliferation effects and human use study.

Purpose: This study aims to examine spatial characteristics of emergency department Chronologically through case studies; and to consider the social implication of these spatial changes. Methods: In this study, a total of eight emergency departments, one for each period, were selected in order to analyze the spatial characteristics. The spatial maps of Space Syntax were employed for analyzing case studies. Results: The spatial configuration of emergency department has been changed from five or more emergency department specialties to four or less specialties such as psychiatric, pediatrics, emergency, and trauma. In the case of care initiation area, the concentrated arrangement mode was switched from the distributed arrangement mode. The spatial maps indicate that it can be seen that the tree structure changes to an annular structure emphasizing the connection between the spaces in the emergency department. This shows that the space efficiency, safe, visual control and flexibility in the planning of the emergency department are important factors affecting the spatial structure of the emergency department. Implications: In the future, it is expected that Korean emergency department will be more focused on efficiency, safe, visual control, and flexibility in the planning as in the case studies of the United States.
