Purpose: The purpose of this study was to identify social support and health status based on characteristics of leisure activity in middle-aged women. Methods: Participants were 148 middle-aged women living in the capital area. Data were collected through self-report questionnaires which were constructed to include leisure activity characteristics, social support and Brodman's CMI. Data were analyzed using t-test, and ANOVA, with SPSS/WIN 14.0. Results: Social support was different depending on leisure type, leisure partner, length of participation in present activity, regularity, and motivation to start activity. Health status was different depending on the length of participation in present activity, and regularity. Conclusion: Because social support and health status depend on characteristics of leisure activity, further study in nursing one how to resolve the physical, psychological, social and health problems that middle-aged women might experience through various leisure activities.

Background: Shoulder external rotation exercises are commonly used to improve the stabilizing ability of the infraspinatus. Although the side-lying wiper exercise (SWE) is the most effective shoulder external rotation exercise to maximize infraspinatus activity, the effect of adduction force on the infraspinatus and posterior deltoid has not been demonstrated. Objects: This study was conducted to investigate whether horizontal adduction force increases infraspinatus activity and decreases posterior deltoid activity. Methods: Twenty-eight healthy subjects (male: 21, female: 7; $age=23.5{\pm}1.8years$; $height=170.1{\pm}7.4cm$; $weight=69.4{\pm}9.6kg$) were recruited. Subjects were asked to perform the SWE under two conditions: (1) general SWE and (2) SWE with adduction force using pressure biofeedback. Surface electromyography (EMG) signals of the infraspinatus and posterior deltoid were recorded during SWE. Paired t-tests were used to compare the EMG activity of the infraspinatus and posterior deltoid between the two conditions. Results: Posterior deltoid muscle activity was significantly decreased following SWE with adduction force ($7.53{\pm}4.52%$) relative to general SWE ($11.68{\pm}8.42%$) (p<.05). However, there was no significant difference in the infraspinatus muscle activity between the SWE with adduction force ($28.33{\pm}12.16%$) and the general SWE ($26.54{\pm}13.69%$) (p>.05). Conclusion: Horizontal adduction force while performing SWE is effective at decreasing posterior deltoid activity.

When logistics system is integrated with production system and marketing system, it takes a very important role of the business management. In general, measurement of logistics cost in logistics system uses the conventional cost assignment method. However the conventional method may result in the incorrect cost because the overhead cost may be incorrectly assigned to the products. Activity-Based Costing(ABC) was proposed as an alternative method which will distribute the overhead cost to each cost obeject more accurately. ABC assigns cost to activities based on the amounts of resources used by resource driver, and assigns cost to cost objects based on the amount of activities driver. This study proposes two heuristic algorithms. The first algorithm selects the best activity driver for each cost object by using correlation analysis. The best activity driver is the one that minimizes the sum of loss cost and measurement cost of activity driver. The second algorithm selects the best number of activities by using correlation analysis. The pair of activities with the highest correlation are combined into one if the saving of measurement cost is no less than the loss due to inaccurate distribution of overhead cost. In order to demonstrate the procedure and validity of the algorithms, Real data of one year from a paper manufacturer are used.

Schisandra chinensis and its fruits have been used as a traditional herbal medicine to treat liver dysfunction, fatigue, and chronic coughs. Several in vitro and in vivo studies suggested that dibenzocyclooctadiene lignans present in Schisandra fruits strongly inhibit CYP3A4 activity. However, reports on the inhibitory potential of dietary Schisandra supplements against CYP3A activity are limited despite their increasing consumption as dietary supplements. In this study, we evaluated the CYP3A-inhibitory potential of four dietary Schisandra supplements in human liver microsomes. At a concentration of 0.05 mg/mL, Schisandra supplements from Nature's Way, Swanson, Planetary Herbals, and Only Natural inhibited CYP3A activity by 93.9, 70.8, 33.6, and 24.8%, respectively. Nature's Way, which exhibited the strongest inhibition against CYP3A, had the highest contents of gomisin B and gomisin C, which potently inhibit CYP3A activity. The in vivo pharmacokinetics of this product should be examined to determine whether the clinical relevance of inhibiting CYP3A activity by dietary Schisandra supplementation.

The purpose of this study was to examine the application of the Activity-based Costing(ABC) system to analyze the cost of nursing services in the delivery room in a major medical center.The results of this study are as follows;1. In order to calculate the cost of nursing activities, 67 activities of staff nurses on a delivery room were identified and classified as direct nursing activities(45.2%), the indirect activities(32.1%), general management activities(13.9%) and others(8.8%).2. Nursing cost in the delivery room was classified into activity cost(29.9%) and common cost(70.1%). Activity cost involved direct activity cost of staff nurses. The common costs were categorized into indirect activity & general management cost of staff nurses, management cost of the head nurse and activity cost of assistants.3. The final cost objects of nursing services in the delivery room were nursing service for women who had normal vaginal deliveries and nursing service for women who had preterm labor.The total cost of nursing service for a woman who had a normal vaginal delivery was 165,710 won (100.0%). The cost incurred through direct activity cost of staff nurses(58,242 won, 35.1%), indirect activity & general management cost of staff nurses (55,643 won, 33.6%), management cost of head nurse (16,211 won, 9.8%), activity cost of assistants (35,614 won, 21.5%).If the number of days of hospitalization was presumed to be 14 days, the total cost of nursing service for woman who had preterm labor would be 1,845,901 won (100.0%). The cost incurred by direct activity cost of staff nurses in the activity cost (341,349 won, 18.5%), indirect activity & general management cost of staff nurses in the common cost(779,002 won, 42.2%), management cost of head nurse(226,954won, 12.3%), activity cost of assistants in the common cost(498,596 won, 27.0%).In this study, the cost of the nursing services in the delivery room was calculated based on the ABC system. The results of this study showed that resources are assigned to the nursing activities in the delivery room and the mechanisms for assigning the cost of activities for nursing services.

Proteases are one of the most abundant classes of enzymes in living organisms and have been considered major targets for drug development. However, despite the ability to specifically cleave their substrates, many attempts to assay protease activity have generally relied upon the use of gel zymography or fluorophore-labeled peptide substrates, which is limited in rapid and multiplex analysis. Here we review the recent advances in nanoparticle (NP)-utilized assays of protease activity focused on in vitro and cell imaging-based approaches. Owing to large surface area and unprecedented physical properties of NPs, these approaches are anticipated to facilitate many applications related to protease activity-based disease diagnosis and drug discovery.
