Uterine bleeding is a physiologic monthly event occuring during the reproductive period of the nonpregnant woman. As with any other physiologic event, normal women have different menstrual patterns and at times, it is difficult to define when normality ends and abnormality begins. Dysfunctional uterine bleeding is an all-inclusive term: its diagnosis usually bepends on the exclusion of local or systemic organic causes. The term dysfunctional refers to alterations in the physiologic mechanism controlling a multitude of cyclic events in the women's reproductive function. These mechanism are primarily neuroendocrine in nature. According to oriental medicine, the Metrorrhagia(崩漏) means an abnormal bleeding of femail genetalia, and is devided to bungjung and bungha. The etiological factors of metrorrhagia are heat of blood, asthenic coldness, asthenia of chong and ren channels, deficiency of blood, deficiency of vital energy, stagnated blood, and asthenia of spleen & stomach.

Purpose: This study was undertaken to identify stroke risk with risk factors and knowledge of stork in women with prehypertension. Methods: A total of 46 pre-hypertensive women in urban area aged 44.8 (SD 11.4) yr old in average were selected by a convenient sampling. Demographic data, risk factors, and knowledge of stroke were assessed through face to face interview. Stroke risk scores were calculated based on points given to age, systolic blood pressure, smoking, DM, and heart disease in Framingham stroke risk score. Data were analyzed by SPSS WIN 12.0 using descriptive statistics, two sample t-test, and Pearson's correlation coefficient. Results: The mean systolic blood pressure of participants was 133.11 mmHg, and HDL cholesterol was lower than the recommended level, although rest of physiologic risk factors were within normal. Of the participants, 82% did not do regular physical activity and 75% did not control fat intake persistently. Mean stroke risk points and knowledge scores were 4.48 and 29.15, respectively, which were significantly different between women with and without persistent controlling fat intake. Conclusion: Results indicate stroke prevention intervention for prehypertensive women should address comprehensively modifying lifestyle as well as physiologic factors, and information focusing on stroke risk factors and warning symptoms.

Mechanical factors in the human body are considered to play a dominant role in low back problems. Various spinal structures. including muscles, act in unison to resist the external load. An estimation of the muscle forces in this structure requires a knowledge of the orientation, location and area of cross-section of the muscles to complete the formulation of a truly three-dimensional mathematical model of the spine. The geometric parameters which are calculated were the line of action, the centroid and physiologic area of cross-section of each muscle as a function of the spinal level. This geometric data were obtained from CT scans of 11 subjects participating in this study.

Objective: This study was designed to identify factors affecting pilots' +Gz tolerance recovery from +Gz induced exhaustion. Background: +Gz tolerance of pilots has been considered as a crucial factor to fly the modern high performance fighter aircrafts. However, the factors affecting pilots' G-tolerance recovery from +Gz induced exhaustion have not been examined in the acceleration research community. Method: A centrifuge profile consisting of a high +Gz run for pilot's exhaustion and a low +Gz run for pilot's recovery and another high +Gz runs for pilot's second exhaustion was designed. The subjects' +Gz tolerance recovery ratio was measured by ratio of second high +Gz run time to the first high +Gz run time. The subjects' +Gz tolerance recovery rate was measured by dividing the subjects' +Gz tolerance recovery ratio by the low +Gz run time. The subjects' G-tolerance recovery rate was analyzed with respect to the subjects' personal factors including subjects' anthropometric and physiologic characteristics, flight time, flying aircraft type and so on. Results: The subjects' previous three-month flight hours (r=-0.336, p=0.039), six-month flight hours (r=-0.403, p=0.012) and one-year flight hours (r=-0.329, p= 0.044) correlated with the subjects' G-tolerance recovery rate. Conclusion: The subjects' G-tolerance recovery rate is clearly related to the subjects' previous flight hours. However, the subjects' anthropometric and physiologic characteristics do not show any statistically significant correlation with the subjects' G-tolerance recovery rate. Application: This research provides a safety critical insight to aviation community by identifying the factors to affect the gravity-induced loss of consciousness (GLOC) of pilots.

Purpose: The purpose of this study was to identify the sleep patterns of nursing students using self-report questionnaire and physiologic measurement, to examine the factors influencing sleep patterns in based on Spielman's model. Methods: Participants were 119 nursing students who were in the clinical practice period. Self-report questionnaires and actigraphy were used to collect the data. Data were analyzed using descriptive statistics, correlation and regression by the SPSS/WIN 21.0 programs. Results: When sleep was measured by self-report questionnaire, 84 students (70.6%) showed poor sleep quality. The mean sleep efficiency was 82.6%, and 67 students(56.3%) showed low sleep efficiency (less than 85.0%). The factors affecting subjective sleep pattern measured by KMLSEQ were circadian sleep type (${\beta}=.28$, ${\rho}=.003$) and alcohol (${\beta}=.20$, ${\rho}=.031$). The factors affecting total sleep time were sedentary behavior (${\beta}=-.27$, ${\rho}=.003$) and daytime sleepiness (${\beta}=-.33$, ${\rho}$<.001). Conclusion: Many nursing students in their clinical practice period expressed sleep disturbance. Factors affecting the perceived sleep measured by the self-report questionnaire and objective sleep evaluated by physiologic measures were different. The evening type of students perceived poor sleep quality, however, sedentary life style and daytime sleepiness resulted in short sleep time. Therefore, more studies measuring the objective sleep characteristics are needed using subjective and objective characteristics.

Neonates have large inter-individual variability in pharmacokinetic parameters of many drugs due to developmental differences. The aim of this study was to investigate the factors affecting the pharmacokinetic parameters of drugs, which are commonly used in critically ill neonates. Factors that reflect physiologic maturation such as gestational age, postnatal age, postconceptional age, birth weight, and current body weight were correlated with pharmacokinetic parameters in neonates, especially preterm infants. Comorbidity characteristics affecting pharmacokinetics in critically ill neonates were perinatal asphyxia, hypoxic ischemic encephalopathy, patent ductus arteriosus (PDA), and renal dysfunction. Administration of indomethacin or ibuprofen in neonates with PDA was associated with the reduced clearance of renally excreted drugs such as vancomycin and amikacin. Therapeutic hypothermia and extracoporeal membrane oxygenation were influencing factors on pharmacokinetic parameters in critically ill neonates. Dosing adjustment and careful monitoring according to the factors affecting pharmacokinetic variability is required for safe and effective pharmacotherapy in neonatal intensive care unit.
