  • Purpose: The purpose of this study was to assess insomnia and the quality of sleep, investigate the concordance between objective and self-report sleep patterns, and identify physiological, psychological, and situational factors influencing insomnia and sleep quality among firefighters. Methods: A descriptive, cross-sectional study was conducted with 103 firefighters in Korea. The collected data were analyzed using SPSS 23.0. Descriptive statistics, the independent t-test, and hierarchical logistic regression analysis were performed. Results: Insomnia was found in 66 (64.1 %) of the total subjects, and the average quality of sleep (PSQI) was 5.65 (SD=2.57). Total sleep time (401.00 minutes) and sleep latency (21.60 minutes) measured using self-reported scales were longer than the ones measured using objective measurements by approximately 48.70 and 17.10 minutes, respectively. Factors related to insomnia included the role as a paramedic (OR=4.28, 95% CI: 1.02~17.92), anxiety (OR=1.12, 95% CI: 1.01~1.24), and sedentary lifestyle (OR=0.85, 95% CI: 0.78~0.94), and factors related to sleep quality were physical illness status (OR=5.17, 95% CI: 1.53~17.51) and social support (OR=0.86, 95% CI: 0.78~0.95). Conclusion: The results show a high prevalence of insomnia, poor quality of sleep and the discrepancy between objective and subjective sleep patterns among firefighters. To promote sleep quality and health, early screening and treatment of anxiety and physical illness are required. It is necessary to conduct further studies examining the relationship between physical activity level and sleep.

  • Objective: The management for the stroke should ,given as soon as possible to be effect. But Patients with stroke symptoms commonly delay many hours before seeking medical attention. We evaluated the factors which are related to the time of hospital arrival after acute stroke. Method: Data were obtained from 317 patients admitted to our hospital within 72 hours of stroke onset. We assessed demographic variables, stoke subtype. referral routes. history of previous stroke, level of consciousness, distance from the place where stroke occurred to hospital, and the time interval between onset of stroke and arrival at the hospital. Results: Mean patient age was 65.99±9.57 years. The mean time interval between onset of stroke and hospital arrival was 17.26±18.69 hours and 128 (40.38%) patients arrived within 6 hours. The patients whoes stoke subtype was infarction, who arrived our hospital by way of other hospital, who had no suffered from previous stroke and who showed no impairement of consciousness was arrived at the hospital late(p<0.05). Conclusion: The majority of patients arrive at the hospital after prolonged delays for multiple reasons, and patients with milder symptoms, for whom treatment might be more effective, were less likely to arrive in time for therapy. Our study suggest that effective education about stroke to the patients and public would be highly necessary.

  • The main current in the pathology of oriental medicine is composed of etiologic factor, pathogenesis and clinical manifestation. The access of a disease is consist of etiologic factor, location of the lesion, nature of the disease and patient's condition. The nature of disease and the property of a drug are inseparably related to each other. The nature of disease is composed of six exogenous factors, cold and heat, deficiendy and excess, Yinyang and pain. Cold nature is divided into cold symptom due to excess and asthenia cold, fever nature is divided into sthenic fever and asthenic fever. According to the location, cold and heat can be subdivided into heat in the upper and cold in the lower, cold in the upper and heat in the lower, exterior cold and interior heat, exterior heat and interior cold. Yin syndrome characterized by hypofunction of the viscera is generated from insufficiency of yang-qi, excess of yin-coldness, deficiency of both qi and the blood.

  • This study examined the consciousness of husbands and wives on babies' cries and its factors which have impacts on their emotional perceptions. For this study, infants' cries were recorded with the participation of 136 pregnant women and 76 husbands, and they conducted self-evaluations regarding their emotional perceptions and personal characteristics. The stimulus used to exhibit the cries of infants were from eighteen recorded cry sample under three situations (hunger, pain, and mother's absence) with six healthy infants (three male and three female) who are over six months. Also, this study dealt with the relationship between emotional assessment and the personal characteristics of mothers and fathers. As a result, the experience of child-rearing has a positive influence on the emotional cry perceptions of husbands and wives, and there was no sex difference in their emotional cry perceptions. A change of recognition, "being parents," has impacts on emotional cry perceptions, but the major factors increasing these impacts depend on the physiological changes of pregnant women and their personal characteristics.

  • Purpose: This study was to investigate the factors influencing quality of life and difference of quality of life in a postmenopausal group compared to premenopausal women. Method: The subjects consisted of 213 women from 40 to 64 years old. The data were collected from June 1, 2003 to June 31, 2004 using structured questionnaires which included questions relating to demographic and obstetric background and 4 scales(climacteric symptoms scale, marital satisfaction scale, sex-role attitude scale, quality of life scale). Result: Comparing pre- and postmenopausal women, significant statistical differences were demonstrated in climacteric symptoms and sex-role attitude. However, quality of life was not different between pre- and postmenopausal women. In premenopausal women, marital satisfaction($32.7\%$) and educational level($8.0\%$) were significant predictors to explain quality of life. Marital satisfaction($12.9\%$) was significant predictor to explain quality of life in postmenopausal women. Conclusion: No difference of quality in life between pre- and postmenopausal women provides information for changing traditional approaches of menopause according to physiological changes as illness. In addition the study showed that it is necessary to use marital satisfaction information when developing nursing interventions to promote the quality of life.

  • The plastochron index (PI) provides possibility on studies of the effects of various environmental factors on morphological and physiological development of plants. The PI of Erickson and Michemlini(1957) could be used merely when leaf n is longer an leaf n+1 is smaller than the references length at any time. If both the lengths of leaf n and n+1 are smaller or longer than the reference length, it could not estimated. In this study, the PI of Erickson and Michelini was complemented and the linear patterns according to leaf arrangement was represented, PI is n-(lnLR-lnLn)/(lnLn-lnLn+1). And when both the lengths of leaf n and n+1 are longer than the length of reference, PI is n+1+(ln Ln+1-lnLR)/(lnLn-lnLn+1). The linear model of PI is changed by the various environmental factors and the linear patterns are different according to leaf arrangement. According to leaf arrangement, the equation of the general regression lines is Yin-(i-j)=a-(n-1)(q1+...+qi-1)-(q1+...+qj-1)+rt+$\varepsilon$. Where Y:the logarithmic of the leaf length in question, i:leaf number hang on the one node, n:the number counting from base, q:spacing on the Y-axis, j:0, 1, 2, ..., r:slope, t:time, $\varepsilon$:error.

  • This study examined the work environment and wearing conditions of industrial protective clothing in shipbuilding workshops. It also investigated the relationship between the wearing sensation of industrial protective clothing and overall comfort, according to work process. In addition, the work posture according to work process was evaluated based on ergonomic factors. The wearing rate of industrial protective clothing was 73.3%, 66.7%, and 60.1% for workers engaged in welding, grinding, and painting, respectively. The harmful work environment factors, listed from most harmful to least harmful, were found to be high temperature pyrogens, noxious fumes, organic solvents, UV rays, and heavy dust. The aspect of wearing performance of industrial protective clothing that was most related to user dissatisfaction was poor sweat absorbency. In terms of the correlation between the overall comfort and the wearing sensation of industrial protective clothing, the satisfaction was low shown in orders of physiological comfort, sensual comfort, and movement comfort.

  • Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.
