Purpose: This study was to examine the change of stress and nursing needs in preterm labor women after hospitalization. Method: Forty seven women with preterm labor who were admitted in two university hospitals participated in the survey and they were completed the questionnaires on admission day and 5th day after admission. Questionnaires included in modified Antepartum Hospital Stressor Inventory (AHSI) and Nursing Needs for Preterm Labor. The collected data were analyzed by paired t-test and Pearson correlation test. Result: The stress level was not decreased significantly after hospitalization. Among them, the stresses about fetus and medical staff were decreased significantly after hospitalization, but those about pregnant women, husband and environment were increased significantly after hospitalization. The difference in the level of nursing needs between the two different days was not significant except the physical needs. The total level of stress and nursing needs were correlated significantly on the 5th day after hospitalization. Conclusion: These results indicate that stress and nursing needs of preterm labor women undergo changes after hospitalization. Therefore, development of the program being followed by stressors which change from day to day and further studies are required in order to examine the decreasing of the stress.

Purpose: To determine the effects of hand massage on nausea and vomiting, and anxiety in children with Iymphocytic leukemia receiving high dose chemotherapy. Method: The children were assigned to an experimental group(15) or a control group(15). All of the children were diagnosed with acute Iymphocytic leukemia and admitted for high dose chemotherapy at C University Medical Center in Seoul. The hand massage was performed for 10 minutes twice a day over three days. To measure the effects of hand massage, the Index of Nausea and Vomiting by Rhodes et al. and the State-Trait Anxiety Inventory for children by Spielberger were used. The level of anxiety was measured by systolic blood pressure, diastolic blood pressure, and pulse rate. Results: The score for nausea and vomiting decreased in the experimental group. State anxiety for the experimental group was significantly more positive than for the control group at the 2nd measurement. There was a significant difference in systolic blood pressure between the two groups. The level of diastolic blood pressure in the two groups decreased significantly over time. Conclusion: Hand massage could be effective in decreasing nausea and vomiting, state anxiety, pulse rate and blood pressure in children with acute leukemia receiving high dose chemotherapy.

Purpose: The purpose of this study was to examine the effects of music therapy on state anxiety and pain among patients undergoing burn dressing changes. Method: A convenience sample of 32 adult burn patients who were eligible and provided consent were included in the study which was a quasi-experimental study of a nonequivalent control group pretest-posttest design. Fifteen patients in the control group received the routine burn dressing changes but 17 patients in the experimental group listened to self-selected music through headphones connected to a CD player during burn dressing changes for three days. All subjects of the music group chose the type of music that would relax them. Before and after burn dressing changes, subjects completed the State Anxiety Inventory and self-report of pain scores. Result: There was a significant reduction in state anxiety before and after burn dressing changes in those who received music therapy in contrast to those who did not receive music therapy. The music group reported lower pain scores before and after burn dressing changes than did the non-music group. Conclusion: These findings indicate that music therapy composed of self-selected music is a valuable intervention for the treatment of pain and anxiety in patients undergoing burn dressing changes.

Biogenic Volatile Organic Compound (BVOC) emissions are estimated with BEIS3.12 (Biogenic Emissions Inventory System version 3.12) over the Seoul Metropolitan Area (SMA) and then used in CMAQ (Community Multiscale Air Quality) simulations for two high ozone episodes in 2004 and 2007 June. The first- and second-order sensitivity coefficients of ozone to BVOC emissions are estimated with High-order Decoupled Direct Method (HDDM) simulation in order to estimate the influence of BVOC emissions on ozone using the Zero-Out Contribution (ZOC) approach. ZOC analysis shows that relative contribution of BVOC emissions on daily maximum 1-hr ozone is as high as 30% for high ozone days above 100 ppb. However simulated isoprene concentrations were over-estimated by a factor of 2 when compared to the observations at the PAMS (Photochemical Air Monitoring Station) for the 2007 episode. When assumed that actual BVOC emissions are 50% less than estimated, the ZOC of BVOC emissions on daily maximum ozone drops by more than 10 ppb for the episode. The result indicates that uncertainty in BVOC emissions may have significant impact on high ozone prediction in the SMA.

Purpose: This study aimed to investigate the correlation between the health behaviors and the aggression in Korean high school students. Methods: This was a cross-sectional study conducted with a survey of 2,676 high school students. Aggression was measured in four categories (physical aggression, verbal aggression, anger and hostility) using the Aggression Questionnaire, a modified hostility inventory by Buss and Perry. Result: Univariate analysis showed that sex, smoking, alcohol, caffeine, pain pills and gastrointestinal drugs were significantly associated with aggression scores. Boys scored higher than girls in terms of physical and verbal aggression. With respect to the habit of self-medication, students who took pain pills in the last 30 days revealed higher scores in all four aggressive constructs. From multivariate analysis, it was found that alcohol, caffeine, smoking, pain pills, sex and gastrointestinal drugs were independently associated with total aggression score in the order of importance. Alcohol and caffeine, among these factors, had strong correlation with all aggressive characteristics. Conclusion: This study identified a consistent association between the aggression of the students and health behavioral factors, but causal relationship remains to be proven.

Purpose: The purpose of this study was to compare the effects of scrambler and transcutaneous electrical nerve stimulation therapy on pain, functional disability, and depression in patients with chronic low back pain. Methods: Twenty patients with chronic stroke were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed scrambler therapy. The control group performed electrical nerve stimulation therapy. Training was conducted once a day for 30 minutes, five days per week, for three weeks. The pain was measured using the numeric rating scale. Functional disability was measured using the Roland-Morris disability questionnaire. Depression was measured using the Beck depression inventory. Results: As a result of comparison between the groups, the experimental and control groups showed significant difference for pain, functional disability and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which scrambler therapy was applied, showed a more significant reduction in pain, functional disability and depression than the control group (p<0.05). Conclusion: Based on these results, scrambler therapy shows positive effects on pain, functional disability, and depression in patients with chronic low back pain.

Purpose: This study examined the effects of aquatic proprioceptive neuromuscular facilitation pattern exercise on the balance, gait ability, and depression in patients with chronic stroke. Methods: Thirty patients with chronic stroke were assigned randomly to an experimental (n=15) or control (n=15) group. The experimental group performed aquatic proprioceptive neuromuscular facilitation pattern exercise. The control group performed ground proprioceptive neuromuscular facilitation pattern exercise. Training was conducted once a day for 30 minutes, five days per week for six weeks. The balance ability was measured using the Berg balance scale. The gait ability was measured using the 10 Meter walk test. Depression was measured using the Beck depression inventory. Results: As a result of a comparison within groups, the experimental and control group showed a significant difference for balance, gait ability, and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which aquatic proprioceptive neuromuscular facilitation pattern exercise was applied, showed more significant changes in balance, gait ability, and depression than the control group (p<0.05). Conclusion: Based on these results, aquatic proprioceptive neuromuscular facilitation pattern exercise effectively improved the balance, gait ability and depression in patients with chronic stroke.

Purpose - We study whether the bullwhip effect is prevalent among Korean firms and how the characteristics of it differ from the ones in other countries. Design/methodology/approach - We obtained quarterly financial and operational information on KOSPI-listed firms in manufacturing, wholesale, and retail industries from 2013 to 2019. We explore the variation of the bullwhip effect across firms and validate hypotheses. Findings - First, we find that for the KOSPI-listed firms, the bullwhip effect is more prevalent compared with the production smoothing. We provide additional findings by using sub-samples of manufacturing firms, wholesaling and retailing firms, big-sized firms, small- and medium-sized firms, domestic-sales intensive firms, and export intensive firms. Second, we show that in general, the bullwhip effect of Korean firms increases with the days in inventory or the demand seasonality ratio. However, the persistence of demand shock does not affect the bullwhip effect of Korean firms. Research implications or Originality - We compare our results with those in other studies that use information on the U.S. and Chinese firms. Our findings show that factors explaining the bullwhip effect across Korean firms have similarities and differences compared with firms in the U.S. and Chinese firms.

Background: Occupational workers at altitudes are more prone to falls, leading to catastrophic outcomes. Acrophobia, height-related anxiety, and affected executive functions lead to postural instabilities, causing falls. This study investigated the effects of repeated virtual height exposure and training on cognitive processing and height-related anxiety. Methods: Twenty-eight healthy volunteers (age 20.48 ± 1.26 years; mass 69.52 ± 13.78 kg) were recruited and tested in seven virtual environments (VE) [ground (G), 2-story altitude (A1), 2-story edge (E1), 4-story altitude (A2), 4-story edge (E2), 6-story altitude (A3), and 6-story edge (E3)] over three days. At each VE, participants identified occupational hazards present in the VE and completed an Attitude Towards Heights Questionnaire (ATHQ) and a modified State-Trait Anxiety Inventory Questionnaire (mSTAIQ). The number of hazards identified and the ATHQ and mSTAIQ scores were analyzed using a 7 (VE; G, A1, A2, A3, E1, E2, E3) x 3 (DAY; DAY 1, DAY 2, DAY 3) factorial repeated measures analysis of variance. Results: The participants identified the lowest number of hazards at A3 and E3 VEs and on DAY 1 compared to other VEs and DAYs. ATHQ scores were lowest at G, A1, and E1 VEs. Conclusion: Cognitive processing is negatively affected by virtual altitudes, while it improves with short-term training. The features of virtual reality, such as higher involvement, engagement, and reliability, make it a better training tool to be considered in ergonomic settings. The findings of this study will provide insights into cognitive dual-tasking at altitude and its challenges, which will aid in minimizing occupational falls.
