Background: Truck driving is a highly sedentary occupation that places workers at risk for chronic health conditions, such as obesity and high blood pressure. The primary purpose of this study was to objectively describe truck drivers' typical physical activity (PA) patterns. Methods: We used ~7-10-day baseline PA actigraphy data samples from drivers in the Safety & Health Involvement For Truckers (SHIFT) study (n = 394). Driver PA patterns (e.g., average number of ≥10 minute Freedson bouts per week, time in bouts, and common days/times for PA) were summarized with descriptive analyses. We also compared objective accelerometer data to self-reports. Results: Drivers' weekly PA averaged 14.4 minutes (SD = 37.0), and most PA occurred between 5-6 pm on Tuesdays and Wednesdays. Drivers overestimated self-reported weekly exercise by over 60 min/week compared to accelerometer data. Conclusion: Our results suggest that objective PA assessment may be warranted over self-report when possible, and timing may be key in future PA intervention work with truck drivers.

A real-case incident occurred where a 9-meter-high segment of a pre-fabricated concrete separation wall unexpectedly collapsed. This collapse was triggered by improperly depositing excavated soil against the wall's back, a condition for which the wall segments were not designed to withstand lateral earth pressure, leading to a flexural failure. The event's analysis, integrating technical data and observational insights, revealed that internal forces at the time of failure significantly exceeded the wall's capacity per standard design. The Lattice Discrete Particle Model (LDPM) further replicates the collapse mechanism. Our approach involved defining various parameter sets to replicate the concrete's mechanical response, consistent with the tested compressive strength. Subsequent stages included calibrating these parameters across different scales and conducting full-scale simulations. These simulations carried out with various parameter sets, were thoroughly analyzed to identify the most representative failure mechanism. We developed an equation from this analysis that quickly correlates the parameters to the wall's load-carry capacity, aligned with the simulation. Additionally, our study examined the wall's post-peak behavior, extending up to the point of collapse. This aspect of the analysis was essential for preventing failure, providing crucial time for intervention, and potentially averting a disaster. However, the reinforced concrete residual state is far from being fully understood. While it's impractical for engineers to depend on the residual state of structural elements during the design phase, comprehending this state is essential for effective response and mitigation strategies after initial failure occurs.

Objective : The aim of the study was to investigate the application of nonpharmacological cognitive interventions in patients with dementia. Methods : We searched published studies in KISS, PubMed, and Sciencedirect databases from January 2013 to December 2017. The main keywords used were "Dementia" AND "Cognitive stimulation OR Cognitive rehabilitation OR Cognitive training" and a total of ten studies were selected for analysis from 753 searched articles. Results : Seven of the ten selected studies showed significant improvements in cognitive function after intervention, whereas three studies showed no improvement in cognitive function; however, activation of brain waves, improvement in the relationship between care givers and patients, improvement in the quality of life of care givers, and improvements in visual motor skills were shown. Mini-Mental State Examination(MMSE) was used as the assessment tool for identifying the effects of the cognitive function improvement, and in four studies the quality of life of dementia patients was measured as an intervention effect. The main subject of the cognitive intervention is patients with mild to moderate dementia. Conclusion : The results of this study can be used as a basis for the selection of intervention methods, as well as their duration and assessment, according to the characteristics of dementia patients.

Purpose: The purpose of this study was to examine the relationship between perceived health state, personality, situational barrier, health promoting behavior, to provide the basic data for health promoting intervention. Method: This study was designed as a descriptive correlation study. Data were 396 undergraduate students of one university in Chung-Buk. The instruments for this study were the modified health promoting behavior scale developed by Bak, Insuk(1995), and the modified perceived health state scale developed by Im, Meeyoung (1998), the modified personality scale developed by Park, Youngbae(1998), the modified situational barrier scale developed by Im, Meeyoung(1998). Result: The results of this study showed that the mean score for perceived health state 2.72, personality 3.35, situational barrier 2.72 and health promoting behavior 2.67. The health promoting behavior categories, scores for 'sanitary life'(3.08), 'self-actualization and interrelationship'(2.93) were higher than the mean score, whereas scores for 'healthy diet'(2.64), 'rest and sleep'(2.62), 'exercise and stress management'(2.49), and 'diet management' (2.25) were lower than the mean score. This study revealed the negative correlation between perceived health state, personality, situational barrier and health promoting behavior in undergraduate students. Conclusion: Perceived health state accounted for 16% and personality accounted for 21.3% of the variance in health promoting behavior in students. Therefore, health promoting programs that increase health state and personality should be developed to promote health behavior and to diminish situational barrier for students in Korea.

Severe acute respiratory syndrome (SARS) is an emerging infectious disease associated with a novel coronavirus (CoV) that was identified and molecularly characterized in 2003. Previous studies on various coronaviruses indicate that protein-protein interactions amongst various coronavirus proteins are critical for viral assembly and morphogenesis. It is necessary to elucidate the molecular mechanism of SARS-CoV replication and rationalize the anti-SARS therapeutic intervention. In this study, we employed an in vitro GST pull-down assay to investigate the interaction between the membrane (M) and the nucleocapsid (N) proteins. Our results show that the interaction between the M and N proteins does take place in vitro. Moreover, we provide an evidence that 12 amino acids domain (194-205) in the M protein is responsible for binding to N protein. Our work will help shed light on the molecular mechanism of the virus assembly and provide valuable information pertaining to rationalization of future anti-viral strategies.

The main objectives of this study were to analyze the concept of hope, so to provide basic data to develop a valid instrument to measure hope, and to develop hope enhancing nursing intervention a program for cancer patients. The hybrid model approach was applied in three phases, the theoretical phase, the empirical phase, and the analytic phase. The study was developed on universal attributes explaining generalized hope and specific hope, which were revealed in a comprehensive review of the literature. In the empirical phase, eight cancer patients undergoing chemotherapy were interviewed to reveal causes, motivation, and their resource of hope according to The Hope Assessment Guide (Farren, Herth, & Popovich, 1995). In the analytical phase, the results of the two previous stages of the study were compared. The results were as follows : In the theoretical phase, six dimensions of hope emerged; affective, cognitive, behavioral, affiliative, temporal and contextual dimension. The antecedent of hope was loss, crisis, uncertainity, and stress. The consequences were renewal, development of new methods, safety, peace and transcendental competence. In the empirical phase, these six dimensions emerged as theoretical phases were verified and specified as these descriptive terms: feeling, intention, expectation, activity, relation, future- orientation, reality and goal-setting. The antecedent factor of hope was occurrence or recurrence of cancer. The consequence of hope was ability to cope with real condition, feeling of safety and comfort, peace, development of new strategy and recovery of disease. The major content of hope in this phase was related to specific hope, but it was also influenced on by general hope. In the analytic phase, general and specific hope was renamed as trait and state hope. All attributes emerged at the empirical phases, and also emerged at the theoretical phase. However, cognitive and contextual dimensions were revised and specified. In conclusion, the concept of hope is divided into trait hope and state hope, and state hope is an anticipatory expectation that occurs at the time of a stressful stimulus, such as being diagnosed with cancer. Hope is a multidimensional dynamic energized mental state which has the dimensions of affective, cognitive, behavioral, affiliative, temporal and contextual. There should be further studies to develope the state and trait hope scale according to definition and attributes of hope investigated in this study. In addition, considering results of the empirical phase, the family is very a important factor as a resource of hope, so it is necessary to consider family in implementing a nursing intervention program to enhance hope.

The purpose of this study was to identify the effect of music therapy on state anxiety, perception of pain of dental patients. The subjects consisted of forty patients undergoing dental treatment at one dental clinic. Twenty eight of them were assigned to the experimental group, while twelve subjects to the control group. The data were collected from June 29 to August 1, 1998 by means of a state anxiety scale (by Spielberger) questionnaire and visual analog scale for pain measurement. The data were analysed with $X^2$-test, t-test, and paired t-test. The results are as follows 1) There were no significant differences between the experimental and the control group on the post treatment the state anxiety score. However, in the experimental group, the state anxiety score decreased significantly after music therapy(t=3.19, p=0.003). In the control group, the state anxiety score did not decrease significantly(t=1.65, p=0.126). Especially, high score group on the state anxiety was found to be of significant differences in the experimental group (t=3.09, p=0.007). 2) There were no significant differences between the experimental and the control group on the post treatment perception of pain. However, after music therapy, the experimental group had a lower post treatment perception of pain than the control group. 3) After music therapy, subjective response of the experimental group was one of relative contentment. From these results, it is concluded that music therapy as a nursing intervention can be effective in decreasing anxiety in dental patients.
